ITEM 1.  BUSINESS

COMPANY BACKGROUND AND HISTORY

         SPACEHAB, Incorporated ("SPACEHAB" or the "Company") was incorporated
in 1984 and is the first company to commercially develop, own and operate both
pressurized habitable modules that provide space-based laboratory research
facilities and cargo services aboard the U.S. Space Shuttle system (the "Space
Shuttle" or "STS") and an unpressurized cargo carrier system. A SPACEHAB Single
Module, when installed in the payload bay of a Space Shuttle, more than doubles
the working and living space available to astronauts for research,
experimentation, habitation and storage. The Company presently offers its
SPACEHAB Modules in a single modular version (the "Single Module") and a double
modular version (the "Double Module"). The Company also offers an unpressurized
cargo carrier system, the "ICC" or "Integrated Cargo Carrier", and is currently
completing the construction of a research double module (the "Research Double
Module" or "RDM"). During the second half of fiscal year ("FY") 1998, the
Company initiated development activities for a new asset, a docking double
module (the "Docking Double Module" or "DDM"), that could be used by NASA to
provide more flexible re-supply services to the ISS and also maintain the ISS
in its proper orbit. The Docking Double Module is intended to carry logistics
and perform research on Space Shuttle missions to the ISS and to enable the
Space Shuttle to re-boost and reposition the ISS. All versions of the SPACEHAB
Modules can accommodate a combination of lockers, racks and soft stowage
arrangements, which are provided as a service primarily to NASA. SPACEHAB
Modules, which have been outfitted with systems to facilitate laboratory
research experiments in the near-weightless ("microgravity") environment of
space, are also capable of transporting food, clothing, equipment and other
vital supplies (collectively, "logistics") to the ISS. SPACEHAB also provides a
full range of pre- and post-flight experiment and payload processing services,
and in-flight operations support to assist astronauts and researchers, in space
and on the ground, in connection with the performance of experiments aboard
SPACEHAB Modules. From June 1993 through June 1999, SPACEHAB Modules have flown
thirteen successful missions on the Space Shuttle.

         To broaden the opportunities for companies to conduct space research,
SPACEHAB has established a "Microgravity Staircase" that provides a
comprehensive portfolio of ground-based, sub-orbital and space-based research
facilities. During FY 1998, SPACEHAB completed a series of marketing agreements,
asset acquisitions and joint ventures that now enable SPACEHAB to offer
researchers progressive exposure to the microgravity environment.

         The Company is committed to expanding its business with NASA while also
diversifying its revenue and customer base by targeting new and related space
services markets. On February 12, 1997, the operating assets and business of
Astrotech Space Operations, L.P. ("Astrotech") were acquired from Northrop
Grumman Corporation. Astrotech is the premier commercial provider of satellite
payload processing facilities in the United States providing launch site
preparation of flight-ready satellites to major



                                       1
<PAGE>   3
U.S. space launch companies and satellite manufacturers, including Lockheed
Martin Corporation ("Lockheed Martin"), Motorola Corporation ("Motorola"), The
Boeing Company ("Boeing") and Orbital Sciences Corporation ("Orbital Sciences").
The Astrotech acquisition diversified SPACEHAB's customer base to include
commercial customers of space satellite payload processing services and
broadened the Company's services to include services in support of manned as
well as unmanned space activities.

          SPACEHAB expanded its core business by acquiring Johnson Engineering
Corporation, ("JE") on July 1, 1998. With over 650 employees, JE performs
several critical services for NASA including flight crew support services,
operations, training and fabrication of mockups at NASA's Neutral Buoyancy
Laboratory ("NBL") and at NASA's Space Vehicle Mockup Facility ("SVMF"), where
astronauts train for both Space Shuttle and ISS missions. JE also designs and
fabricates flight hardware, such as flight crew equipment and crew quarters
habitability outfitting as well as providing stowage integration services. JE is
also responsible for configuration management of the ISS.

         SPACEHAB's fundamental business strategy is based on carefully
anticipating customer requirements, investing capital to develop space-flight
assets, contracting with established aerospace companies for engineering and
asset production while retaining ownership of these assets and providing
innovative, cost-effective solutions that meet customer requirements using
fixed-price service contracts. This strategy has been successful for the
Company in obtaining three significant contracts with NASA: a $184.2 million
Commercial Middeck Augmentation Module contract (the "CMAM Contract") for five
missions, a $91.5 million contract for four missions and three option missions
(all of which were exercised) to the Mir Space Station (the "Mir Contract") and
a $68.2 million Research and Logistics Mission Support Contract (the "REALMS
Contract") for four missions and six option missions. The REALMS Contract
provides an opportunity for the Company to provide similar services to
commercial customers. Contracts with commercial customers on STS-95 and
STS-107 are approximately $26.1 million.

         The CMAM Contract, signed in November 1990, required SPACEHAB to
furnish NASA with SPACEHAB module accommodations for experiments developed by
the Centers for the Commercial Development of Space ("CCDS") on five Space
Shuttle missions. The fifth and final CMAM mission was completed successfully
during September 1996.

         The basic Mir Contract signed in July 1995 required the Company to
provide Single and Double Module accommodations for the provision of logistics
resupply to the Mir Space Station on four Space Shuttle missions. The fourth
mission, STS-84, was completed successfully in May 1997. In addition, in
September 1996, the Company entered into agreements with the Japanese Space
Agency ("NASDA") and the European Space Agency ("ESA") (collectively, the
"NASDA/ESA Contract"). Pursuant to the NASDA/ESA Contract, SPACEHAB provided
hardware and integration and operations for scientific microgravity experiments
to NASDA and ESA aboard the Logistics Double Module on STS-84.

         In June 1997, NASA exercised all three options for additional missions
for $39.0 million under the Mir Contract. The Mir Contract options called for
two Logistics Double Module missions and one Single Module mission that were
successfully completed in September 1997, January 1998 and June 1998,
respectively.

         The REALMS Contract, signed in December 1997, requires that the Company
provide a single and a double research module to support microgravity research
payloads on two missions and two double logistics module flights to the ISS to
support outfitting of the ISS. STS-95, a research mission, flew in October 1998,
STS-96, a logistics mission, flew in May 1999. STS-101, a logistics mission, is
scheduled to fly in December 1999 and STS-107, a research mission, is scheduled
to fly in December 2000. The REALMS Contract provides an opportunity for the
Company to provide similar services to commercial customers on STS-95 and
STS-107. During FY 1998, the Company entered into agreements with NASDA, ESA,
the Canadian Space Agency ("CSA") and the Japanese Broadcasting Agency ("NHK")
(collectively, the "STS-95 Commercial Customers"). Pursuant to the agreements,
SPACEHAB provided hardware and integration and operations for scientific
microgravity experiments to the STS-95 Commercial Customers aboard the Single
Research Module on STS-95. The Company completed integration and



                                       2
<PAGE>   4
operations efforts for the STS-95 and STS-96 missions and began integration and
operations efforts for STS-101 and STS-107 during FY 1999 reporting $39.1
million in revenue for these missions under the percentage-of-completion revenue
recognition policy.

         JE operates under the Flight Crew Systems Development Contract (the
"FCSD Contract") with NASA, a $326.3 million multitask contract which commenced
in May 1993. JE performs several critical services for NASA including flight
crew support services, operations, training and fabrication of mockups at NASA's
Neutral Buoyancy Laboratory and at NASA's Space Vehicle Mockup Facility, where
astronauts train for both Space Shuttle and ISS missions. JE also designs and
fabricates flight hardware, such as flight crew equipment and crew quarters
habitability outfitting as well as providing stowage integration services. JE is
also responsible for configuration management of the ISS.

INDUSTRY OVERVIEW

         The U.S. space program encompasses four broad objectives: to advance
scientific research, to establish a permanent human presence in space, to
develop new technologies that contribute to U.S. economic growth and security
and to foster improved international relations through peaceful cooperation in
space with Europe, Japan, Russia and other nations. SPACEHAB is focused on two
markets: (i) microgravity and life sciences space research and (ii) space
support services such as space station logistics and resupply, ground operations
and payload processing and training.

         Microgravity and Life Sciences Space Research

         In orbit, the forces of inertia and gravity counterbalance each other,
thereby creating a condition of near weightlessness known as "microgravity." In
a microgravity environment, materials and living matter behave in fundamentally
different ways than they do on Earth. This phenomenon has stimulated worldwide
interest from scientists and commercial researchers who are seeking improved
ways to manipulate and process materials and to study biological processes that
cannot otherwise be achieved in ground-based laboratories.

         The demand for access to a microgravity environment can be divided into
two broad categories: scientific research and commercial applications. NASA and
other U.S. and international government research organizations provide support
for both basic scientific research and its commercial applications to determine
the fundamental effects that gravity has on physical processes.

         Space Support Services and Training

         Space support services include providing logistics and payload
processing support to NASA, other governments and commercial customers of the
Space Shuttle and the ISS. Permanently orbiting facilities such as the ISS
require reliable sources of logistics: food, clothing, equipment and supplies
that sustain the astronauts and enable them to conduct research. NASA's current
plans call for the Space Shuttle to be launched at least seven times per year
for the foreseeable future. As currently planned, the ISS will require
approximately five Space Shuttle logistics missions per year.

         In order to support the Space Shuttle and ISS operations, NASA requires
ground operations and payload support services before and after each mission.
Payload processing operations entail payload scheduling, mission planning,
safety/certification analysis, physical integration of the payload into its
carrier (such as SPACEHAB modules), the integration of the carriers into the
Space Shuttle's cargo bay, flight operations, technical data gathering and
synthesis, and launch and landing site activities. Space support services also
involve the provision of specialized services and support near launch sites for
commercial satellite manufacturers and launch services. These activities include
mechanical assembly or re-assembly, electrical check, calibration, liquid
propellant loading and related activities.

         A significant component of Space Support Services includes managing all
training operations and facility engineering at the NBL. NASA also requires
design and fabrication of full-scale mockups of the



                                       3
<PAGE>   5
ISS elements used in NBL and SVMF training and the development of hardware for
the ISS crew living quarters that is scheduled for launch in 2003.

PRODUCTS AND SERVICES

         SPACEHAB Single Modules are aluminum cylinders, measuring 10 feet in
length by 13.5 feet in diameter, that incorporate a patented design including a
truncated top and flat-end caps. These fully instrumented modules provide
experiment resources such as power, data management, thermal control and vacuum
venting. SPACEHAB Single Modules are employed primarily for research missions
such as the STS-95 flight that carried senator John Glenn back into space in
October 1998. In FY 1996, the Company completed a development program and
introduced the Logistics Double Module. This module was optimized to carry
logistics and was used by NASA to carry vital supplies to the astronauts and
cosmonauts who resided on the Russian space station Mir. SPACEHAB invested $12.5
million in the design, development, and production of the Logistics Double
Module. During FY 1997, in an effort to anticipate the need of customers, the
Company began the full-scale development and construction of its Research Module
with double module hardware, which when combined with a Single Module becomes
the RDM. The RDM is fully dedicated to microgravity research and is under
contract for the STS-107 mission which is scheduled to fly in December 2000.
Expenditures for the RDM through FY 1999 were $34.3 million. The Company
anticipates total expenditures of approximately $5.7 million to complete this
asset and place it into service. The Company expects that, in order to
completely realize its investment expenditures for the RDM, this module must be
used in seven missions of the RDM.

         The Company expects that the RDM will meet or exceed all of NASA's
projected requirements for dedicated microgravity and life sciences research
that had been performed by Spacelab, the U.S. government-owned habitable module,
which was retired after its final mission in April 1998. As a result of the
retirement of NASA's Spacelab, the Company believes that its flight-proven
modules position SPACEHAB to become the sole provider of crew-tended
microgravity research capabilities for the Space Shuttles. The Company also
initiated preliminary development activities for the DDM, which could be used by
NASA to maintain the ISS in the proper orbit while providing more flexible
re-supply services to the ISS utilizing the Space shuttle Columbia.

         SPACEHAB has addressed the need to carry unpressurized cargo to the ISS
by designing and developing the ICC. The ICC can be used singularly or in
combination with SPACEHAB Single or Double Modules to provide the optimum mix of
pressurized and unpressurized cargo on a single mission to the ISS. The ICC was
first flown on the first supply mission to the ISS, STS-96, in May 1999. In
order to more fully meet NASA's requirements for attached cargo, the Company has
initiated preliminary design efforts of a vertical carrier and other derivatives
with characteristics similar to the ICC.

         In 1998, the Company built on a foundation of existing microgravity
research capabilities by establishing a "Microgravity Staircase" that offers
researchers a broader array of services to tailor experiments to specific
microgravity environments and budgets. The Company entered into a joint venture
with Guigne' Technologies Ltd., to build the SpaceDRUMS (TM) facility, a
facility that uses acoustic energy to position samples inside an experiment
device for "containerless processing", which is scheduled to be the first
commercial research facility on the ISS.

         SPACEHAB's Astrotech payload processing business exclusively serves the
commercial satellite manufacturing and launch services industries in Florida and
at the Vandenberg Air Force Base in California. Although payload processing is
generally associated with the final preparation of a satellite or other space
payload for launch, it is also the first step in the launch process and requires
specialized facilities and support usually located at the launch site.
Astrotech's payload processing activities provide the necessary resources for
mechanical assembly or reassembly, electrical check, calibration, liquid
propellant loading and numerous other related activities. Additionally,
Astrotech's specialized facilities include, but are not limited to, clean rooms,
airlock systems, overhead crane systems, hazard-proof work areas and
environmentally controlled rooms.



                                       4
<PAGE>   6
         Astrotech completed the expansion of its Florida facility in 1998 to
add a new encapsulation high bay that enables parallel processing activities in
support of the new Atlas II and Delta III launch vehicle payloads. The expansion
also will support the small and medium classes of the Air Force's new Evolved
Expendable Launch Vehicle ("EELV"), which is scheduled to begin commercial
payload launch activities in 2001. Astrotech also completed an expansion of its
Vandenberg facility during 1998. Expenditures for these expansions were
approximately $4.0 million.

         In FY 1999, Astrotech acquired an additional 23.5 acres of land
adjoining its existing Florida site to support the planned construction of
additional payload processing facilities to support the increased projected
launch rate and larger sized payloads associated with the new EELV's being
developed by Boeing and Lockheed Martin under Air Force contracts. Astrotech
initially plans to support commercial payload launches on the Boeing Delta IV,
which is scheduled to begin operations in 2001. Expenditures for this expansion
in FY 1999 were approximately $1.1 million.

         Astrotech operates its payload processing services under exclusive
multiyear agreements with Lockheed Martin to support the processing of all
commercial Atlas payloads and with Boeing to support the processing of all Delta
payloads launched from Cape Canaveral Air Station, Florida and Vandenberg Air
Force Base, California. Astrotech also has a similar arrangement with Boeing to
support the processing of all Sea Launch payloads at Boeing's facility in Long
Beach, California.

         Astrotech continues its pursuit of a second major business area,
providing sounding rocket flight hardware and launch services. In December 1998,
Astrotech entered into a relationship with Alliant Tech Services, Inc., located
in Rocket Center, WV, to develop a new sounding rocket system, named the
"Oriole." Astrotech plans to market the Oriole to NASA in support of its
suborbital microgravity and scientific research programs, and to the Department
of Defense ("DoD") in support of its Theater High Altitude Air Defense ("THAAD")
target missile programs. The test launch of the Oriole is expected to occur in
December 1999.

         Astrotech also plans to pursue additional opportunities, including:
(i) providing payload processing facilities and services to new U.S. Government
customers in the defense and intelligence communities; (ii) supporting new space
launch facilities and related payload processing functions internationally and
(iii) expanding its sounding rocket services to include the provision of
microgravity research by developing research facilities and flight hardware.

         On July 1, 1998, SPACEHAB broadened its core business by acquiring
Johnson Engineering. JE performs several critical services for NASA including
flight crew support services, operations, training and fabrication of mockups at
NASA's Neutral Buoyancy Laboratory and at NASA's Space Vehicle Mockup Facility,
where astronauts train for both Space Shuttle and ISS missions. JE also designs
and fabricates flight hardware, such as flight crew equipment and crew quarters
habitability outfitting as well as providing stowage integration services. JE is
also responsible for configuration management of the ISS. JE's ability to
perform detailed design, fabrication, and operations complements the Company's
traditional strengths in conceptual design and program management. The
acquisition of JE provides many of the critical skills and capabilities used to
perform SPACEHAB services that currently are acquired through subcontracting
relationships.

         JE primarily operates under the FCSD Contract which is currently a
$326.3 million multitask cost-plus-award and incentive-fee contract. The
contract commenced in May 1993 and will conclude in April 2001 although NASA has
the option to exercise a one-year extension.

         The Company continues to pursue new business opportunities by
identifying customer requirements and creating and implementing innovative
technical solutions. The Company believes that the demand for microgravity and
life sciences research conducted on SPACEHAB Modules and demand for the use of
its modules for logistics support and other infrastructure services including
communications, power supply and refueling and reboosting services will increase
both during the assembly phase and after the ISS becomes fully operational. The
ISS is the largest engineering and scientific project ever undertaken. More



                                       5
<PAGE>   7
than a dozen nations, led by the United States, Russia, Japan and the European
Community, have spent over $25 billion to date and will spend over $90 billion
to develop, build, launch and operate the ISS. The ISS assembly began in late
1998. In addition, the Company also believes that the increasing demand for
satellites and the improvements in satellite technology will continue to provide
opportunities in the satellite launch services field.

COMPANY STRATEGY

         SPACEHAB's goal is to be recognized as a global market leader providing
products and services supporting the human space flight, logistics and satellite
launch industries. The Company seeks to achieve this goal through implementation
of the following strategy:

     1. Focusing on Quality of Service. SPACEHAB has had thirteen Shuttle
Missions to date, all of which have been completed successfully. The Company
intends to maintain and enhance its reputation for product reliability, process
innovation and performance excellence.

     2. Expanding Scope of Business. SPACEHAB continuously evaluates
opportunities to offer new products and services to its customer base and to
develop assets and acquire complementary, attractively valued businesses. For
example, the Company is in the process of constructing the Research Double
Module and developing the Docking Double Module and has developed and flown the
Integrated Cargo Carrier. Based on SPACEHAB's continuing involvement in
microgravity research and logistics Space Shuttle missions, and its close
interaction with NASA and other users of its SPACEHAB Module services, the
Company is well positioned to anticipate emerging requirements for new services
in the human space flight industry. In 1998, the Company built on its foundation
of microgravity research services by establishing a "Microgravity Staircase."
The Microgravity Staircase offers researchers a broader array of services to
tailor experiments to specific microgravity environments and budgets. With the
acquisition of Astrotech on February 12, 1997, the Company diversified its
revenue and customer base targeting new and related space services markets.
Astrotech is the premier commercial provider of satellite payload processing
facilities in the United States providing launch site preparation of
flight-ready satellites to major U.S. space launch companies and satellite
manufacturers. The acquisition of JE on July 1, 1998 complements SPACEHAB's
traditional strengths in conceptual design and program management while adding
skills in engineering, design and training critical to NASA as well as the
successful completion of the ISS.

     3. Maintaining Position as Low-Price Provider. The Company continues to
offer its payload processing and logistics support services to NASA and other
customers using SPACEHAB owned assets, on a fixed-price basis that the Company
believes is significantly lower than the cost-plus basis used by traditional
aerospace contractors. Through the focus and rigorous application of commercial
best practices in the development and operation of its hardware and facilities,
SPACEHAB substantially reduces the cost, time and complexity that burden
conventional government contractors providing services under cost-plus
contracts.

     JE performs services under a cost-plus award and incentive fee contract for
government services that is requested by and directed by NASA. This contract
form provides for the lowest cost to the government by requiring a separate
negotiation of the price for each task order, thereby allowing JE to implement
commercial best practices to reduce cost. JE's capabilities also provide a base
with which to pursue commercial opportunities.

     4. Continuing Entrepreneurial Initiative. The Company continues to develop
and offer innovative business arrangements to meet NASA and other customer
requirements. The Company has repeatedly taken the initiative to improve its
modules and payload processing services and to deploy new assets in anticipation
of customer needs. By focusing on the quality, cost and responsiveness of its
services, and by attracting and recruiting highly talented and experienced
personnel into its distinctly entrepreneurial organization, SPACEHAB seeks to
distinguish itself as an innovative and effective provider of commercial



                                       6
<PAGE>   8
space services while achieving higher contract profit margins for module
contracts than are customary in traditional government aerospace contracts.

     5. Leveraging International Strategic Alliances. The Company seeks to
create and maintain strategic alliances with key international players in the
space industry. Such relationships include Mitsubishi Corporation in Japan;
DaimlerChrysler Aerospace AG ("DASA"), Alenia Spazio S.p.A. ("Alenia") and
Intospace GmbH in Europe; and RSC Energia in Russia. On August 2, 1999, DASA
strengthened its strategic relationship with the Company by agreeing to purchase
a $12.0 million equity stake in SPACEHAB. The Company believes these alliances
have produced and will continue to produce business opportunities with these
partners, the governments of their respective countries and other industries
within those countries.

         Through the Company's contracts, it continues to implement its business
strategy by identifying customer requirements, creating innovative technical
solutions, raising private capital to develop assets and providing services
pursuant to those contracts.

         Approximately $85.8 million (or 79.7 percent) of the Company's FY 1999
revenue was generated from two NASA contracts - the REALMS Contract and the FCSD
Contract. While Astrotech, and the STS-95 and STS-107 commercial customer
contracts represented additional revenue sources, the Company anticipates that
revenue from NASA will continue to account for a significant amount of the
Company's revenue over the next several years. There are no assurances, however,
that NASA will require the Company's module services in the future. Therefore,
the Company's failure to execute new contracts with NASA would have a material
adverse effect on the Company's financial condition and results of operations.
Additionally, a significant portion of the revenue for JE is derived under
contracts with NASA. Accordingly, the Company continues to focus its efforts on
diversifying its customer base to include commercial companies, as evidenced
with the Astrotech acquisition.

RESEARCH AND DEVELOPMENT

         The Company believes that the timely development of new products and
enhancements to existing hardware are essential to maintaining its competitive
position. In the past three fiscal years, the Company has spent an aggregate of
approximately $9.7 million on research and development.

         Approximately $1.0 million of the Company's research and development
expenditures for FY 1999 were spent on the development of a new product line for
Astrotech, sounding rockets. In addition, $0.7 million was spent on various
studies conducted by third parties. In 1998 and 1997, approximately $1.9 million
and $0.7 million, respectively, was spent on the design, development and
qualification of the new SPACEHAB Universal Communications System ("SHUCS").
Beginning in FY 1996 and continuing throughout FY 1998, the Company had been
working on the development of this new proprietary module communications system
that will be independent of the Space Shuttle's existing data downlink. SPACEHAB
began capital asset construction of SHUCS in the fourth quarter of FY 1998. In
addition, in 1998, the Company spent approximately $0.6 million for research and
development of the ICC. SPACEHAB began capital asset construction of the ICC in
FY 1999. Completion of this asset expands the Company's product and service
lines to meet market requirements for low-cost unpressurized carriers for
research experiments and cargo. SPACEHAB developed the ICC to carry
unpressurized cargo to the ISS, based on a patented pallet technology (the
"Unpressurized Cargo Pallet" or "UCP"), which can be used independently or in
tandem with the SPACEHAB Single or Double Modules. The ICC's design is such that
it is located in what is ordinarily unused volume in the front of the Space
Shuttle's cargo bay. By expanding the capabilities of the Space Shuttle and by
offering flexibility in the mix of pressurized and unpressurized cargo carried
on each mission, the Company believes that the ICC could become the preferred
method for providing logistics and utilization resupply to the ISS. The Company
also incurred $1.3 million, $1.7 million and $0.4 million in other research and
development expenditures during fiscal years 1999, 1998 and 1997 respectively.

COMPETITION

         Currently, there are no other companies that compete directly with
SPACEHAB in providing pressurized module services that are carried aboard the
Space Shuttles. NASA had a government-owned and operated system, Spacelab, which
provided services similar to those provided by SPACEHAB modules. However, NASA
has terminated the Spacelab program with its final mission in April 1998. The
Company has commenced the design and construction of the Research Double Module
under a contract with Boeing (formerly McDonnell Douglas Aerospace). The
Research Double Module represents a commercial replacement for NASA's Spacelab.
The Company believes that this module will significantly outperform Spacelab in
terms of technology, capacity, functionality and cost-effectiveness.

         The Company's long-term strategy for growth is to provide research,
logistics, infrastructure and payload processing services to NASA and others
during the International Space Station era. This strategy could require the
Company to compete with commercial companies such as Lockheed-Martin, Boeing and
others who have existing NASA support contracts, greater financial resources and
manufacturing capabilities, and larger marketing, sales and technical
organizations than the Company. In FY 1997, SPACEHAB entered into an agreement
with United Space Alliance ("USA"), a Boeing and Lockheed Martin joint venture,
to expand the commercial use of the Space Shuttle fleet. Although this agreement
has expired, SPACEHAB and USA are continuing to pursue joint business
opportunities. SPACEHAB's existing strategic relationships with DASA, Mitsubishi
Corporation, Boeing and Alenia, may provide additional opportunities for
teaming and partnerships that management believes will enable the Company to
compete for market share.

         The Italian Space Agency has contracted to build three multi-purpose
logistics modules ("MPLM") intended for use in connection with the ISS. Although
the MPLM provides similar services as SPACEHAB's Modules for ISS logistics
missions, SPACEHAB believes that its Modules are complementary to the MPLM. Each
module is expected to be used for special situations, e.g.- the MPLM is expected
to be used when a requirement exists for heavy construction materials; when the
requirement exists for crew rotation, food, supplies and equipment, the Spacehab
modules would be used due in part to the flexibility and late access
capabilities of the SPACEHAB modules. Of the five planned or possible logistics
missions per year to the ISS, the Company expects that two or three will be
SPACEHAB missions with the remainder being MPLM missions.

         Astrotech's payload processing facilities are located in Florida and
California. At present, management believes that Astrotech's U.S. competition is
limited to the California Vandenberg Air Force Base launch site where a
competitor, California Commercial Spaceport, Inc. ("CCSI") is located. CCSI was
established by obtaining surplus U.S. Air Force facilities at the VAFB launch
complex before Astrotech established its facilities there and when no commercial
alternative was available. To the Company's knowledge, CCSI has won several
contracts to process NASA spacecraft for launch from VAFB. CCSI does not have
payload processing facilities in Florida, where the majority of U.S. commercial
satellite launches occur.

         JE's competitors include Boeing, Lockheed-Martin, United Space
Alliance, Raytheon Barrios Technologies, Hernandez Engineering, Cimarron and
Oceaneering Space & Thermal Systems.

BACKLOG

         A significant portion of the Company's revenue is currently generated
from its contracts with NASA that, similar to contracts with other agencies of
the U.S. government, contain provisions pursuant to which NASA may terminate the
contract "for convenience." The Company's contracts with NASA are conditioned by
its terms upon NASA receiving an adequate annual appropriation of funds from the
U.S. Congress. Failure to receive funds from Congress or a withdrawal by
Congress of prior appropriations would permit NASA to terminate its contracts
with SPACEHAB "for convenience." For the government's fiscal year 1999, both the
U.S. Senate and House of Representatives have authorized and approved an annual
appropriation of $13.7 billion for NASA, including $2.3 billion for the ISS,
indicating a




                                       8
<PAGE>   10
commitment by the government to the space industry. However, there can be no
assurance that the level of approved funding will be adequate for NASA to
complete all of the initiatives including those relating to the contracts with
the Company.

         SPACEHAB anticipates that a portion of future revenue will be derived
from contracts with entities other than agencies of the U.S. government that
will not be subject to federal contract regulations such as termination "for
convenience of the government" or federal government funding restrictions.
However, to the extent that such contracts require the use of the Space Shuttle
for transportation, these systems must be available and will have to be obtained
at a reasonable cost to SPACEHAB.

         As of June 30, 1999, the Company's contract backlog is estimated to be
approximately $167.3 million, of which $149.5 million represents U.S. government
backlog and $17.8 million represents non-U.S government contracts.

CERTAIN REGULATORY MATTERS

         The Company is subject to federal, state and local laws and regulations
designed to protect the environment and to regulate the discharge of materials
into the environment. The Company believes that its policies, practices and
procedures are properly designed to prevent unreasonable risk of environmental
damage and consequential financial liability to the Company. Compliance with
environmental laws and regulations and technology export requirements has not
had in the past, and, the Company believes, will not have in the future,
material effects on the capital expenditures, earnings or competitive position
of the Company.

EMPLOYEES

         As of June 30, 1999, the Company employed 745 regular employees, 28 of
whom are employed by the Astrotech subsidiary and 659 are employed by JE. Of
these 745 employees, 111 (approximately 15 percent) hold advanced degrees,
including 11 who hold doctorate degrees. Additionally, a significant number of
the Company's employees have experience in both the space industry and/or
governmental space agencies, with a special expertise in commercial space and
human space flight. None of the Company's employees are covered by collective
bargaining agreements. Underlying all of SPACEHAB's efforts has been the
dedication and skill of its personnel. The Company believes that the dedication
of its employees is critical to its success and that its relations with its
employees are excellent.

         The Company has never paid cash dividends. It is the present policy of
the Company to retain earnings to finance the growth and development of its
business and, therefore, the Company does not anticipate paying cash dividends
on its Common Stock in the foreseeable future.

         The Company has authorized 30,000,000 shares of Common Stock. At July
24, 1999, 11,229,646 shares of Common Stock were outstanding. The Company had
approximately 2,151 shareholders of record and beneficial holders of its Common
Stock on June 30, 1999.

         The Company has authorized and issued 975,000 shares of preferred
stock. On August 2, 1999, DASA, a shareholder, agreed to purchase an additional
$12.0 million equity stake in SPACEHAB representing 1,333,334 shares of Series B
Senior Convertible Preferred Stock. Under the agreement DASA purchased all of
SPACEHAB's 975,000 authorized and unissued shares of preferred stock. The other
358,334 shares of Series B Senior Convertible Preferred Stock will be issued
upon shareholder approval of a proposal to increase the number of authorized
shares of preferred stock that will be presented at the next stockholders
meeting scheduled for October 14, 1999. The preferred stock purchase will
increase DASA'S investment interest in SPACEHAB to approximately 11.5 percent.
The Series B Senior Convertible Preferred Stock is convertible at the holders'
option on the basis of one share of Preferred Stock for one share of Common
Stock, provides the holder to a right to vote on an "as converted" basis the
equivalent number of shares of Common Stock and has preference in liquidation,
dissolution or winding up of $9.00 per preferred share. No dividends are payable
on the convertible preferred shares.



SALES OF UNREGISTERED SECURITIES

         During FY 1999, the Company issued no unregistered securities.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS.

GENERAL

         SPACEHAB was incorporated in 1984 to commercially develop space habitat
modules to operate in the cargo bay of the Space Shuttles. SPACEHAB, along with
the Astrotech and JE subsidiaries define the Company.

         During FY 1998 the Company operated under two contracts with NASA.
First, the Mir Contract, with a total contract value of $91.5 million, including
$39.0 million for three Mir option missions that were flown in FY 1998. Second,
the REALMS Contract, with a total contract value of $44.9 million consisting of
three missions, two of which were flown in October of 1998 and in May of 1999.
The remaining mission to be flown under the REALMS Contract is scheduled for
December of 2000. This contract also provides SPACEHAB an opportunity to have
direct commercial relationships with other space agencies by providing them
research space in the modules. In fact, on the October 1998 flight, most of the
revenue recognized came from customers other than NASA. The Company's revenues
for FY 1998 were generated primarily from the Mir Contract, the REALMS Contract,
and through the Company's commercial customer contracts. The Company's revenues
for FY 1999 were generated primarily from the REALMS Contract, with an
additional mission scheduled for December 1999, and the FCSD Contract.

         SPACEHAB generates revenue by providing a turnkey service that includes
access to the modules and provides integration and operations support services
to scientists and researchers responsible for the experiments and/or logistics
supplies for module missions aboard the Space Shuttle System and under the FCSD
Contract. Under the CMAM and Mir Contracts, the Company recognized revenue only
at the completion of each Space Shuttle mission using Company assets.
Accordingly, the Company's quarterly revenue and profits fluctuated dramatically
based on NASA's launch schedule and will continue to do so for any contract for
which revenue is recognized only upon completion of a mission. For the REALMS
Contract and for new contract awards for which the capability to successfully
complete the contract can be demonstrated at contract inception, revenue
recognition under the percentage-of-completion method is being reported based on
costs incurred over the period of the contract. The percentage-of-completion
method results in the recognition of revenue over the period of contract
performance, thereby decreasing the quarter-by-quarter fluctuations of reported
revenue.

         The expenses associated with the operations of SPACEHAB are recorded
differently based on the type of expense. Costs of revenue include integration
and operations expenses associated with the performance of two types of efforts:
(i) sustaining engineering in support of all missions under a contract and (ii)
mission specific support. Expenses associated with sustaining engineering are
expensed as incurred. Mission specific expenses relating to the CMAM Contract
and the Mir Contract were deferred as assets and not expensed until the specific
Space Shuttle mission was flown and the related revenue was recognized. Costs
associated with the performance of the contracts using the
percentage-of-completion method of revenue recognition are expensed as incurred.
Costs associated with the cost-plus-award and incentive fee contracts are
expensed as incurred. Other costs of revenue include depreciation expense and
costs associated with the Astrotech payload processing facilities. Flight
related insurance covering transportation of the SPACEHAB Modules from
SPACEHAB's payload processing facility to the Space Shuttle, in-flight insurance
and third-party liability insurance are also included in costs of revenue and
are recorded as incurred. Marketing, general and administrative and interest and
other expenses are recognized when incurred.



                                       13
<PAGE>   15
         Astrotech revenue is derived from various multi-year fixed-price
contracts with satellite and launch vehicle manufacturers. The services and
facilities Astrotech provides to its customers support the final assembly,
checkout and countdown functions associated with preparing a satellite for
launch. This preparation includes: the final assembly and checkout of the
satellite, installation of the solid rocket motors, loading of the liquid
propellant, encapsulation of the satellite in the launch vehicle, transportation
to the launch pad and command and control of the satellite during pre-launch
countdown. Revenue provided by the Astrotech payload processing facilities is
recognized ratably over the occupancy period of the satellites in the Astrotech
facilities.

         Johnson Engineering's revenue is derived primarily from the FCSD
Contract which is a $326.3 million multitask contract which will conclude in
April 2001, although NASA has the option to exercise a one year extension. JE
performs services under a cost-plus award and incentive fee contract for
government services that is requested by and directed by NASA.

RESULTS OF OPERATIONS

         FY 1997 results include the operations of Astrotech subsequent to its
acquisition on February 12, 1997. In addition, FY 1999 results include JE that
was acquired July 1, 1998.

Fiscal Year Ended June 30, 1999 as Compared to the Fiscal Year Ended June 30,
1998

         Revenue. The Company's revenue increased approximately 68% to
approximately $107.7 million for the year ended June 30, 1999, as compared to
$64.1 million for the year ended June 30, 1998. For the year ended June 30,
1999, $39.1 million was recognized from the REALMS contract and related
commercial customers, $9.8 million from Astrotech, $58.4 million from JE and
$0.4 of miscellaneous revenue. Conversely, for the year ended June 30, 1998
revenue of $39.0 million was recognized from the Mir Contract, $14.3 million
from the REALMS Contract and related commercial customers and $10.8 million from
Astrotech. The decrease in module revenue from the year ended June 30, 1998 is
attributable to the delay in the ISS assembly. Astrotech's revenue declined from
the year ended June 30, 1998 due to launch vehicle failures which have been
subsequently corrected.

         Costs of Revenue. Costs of revenue for the year ended June 30, 1999,
increased 146% to $89.3 million, as compared to $36.3 million for the year ended
June 30, 1998. For the year ended June 30, 1999, $25.9 million of costs was for
integration and operation costs under the REALMS Contract and related commercial
customers, $4.6 million was for integration and operations at Astrotech, $53.8
million for cost of revenue at JE, and depreciation of $5.0 million. In
contrast, the primary costs of revenue for the year ended June 30, 1998, are
$19.2 million for integration and operation costs under the Mir Contract, $7.8
million under the REALMS Contract and related commercial customers, $4.4 million
for integration and operations at Astrotech, and depreciation of $4.9 million.

         Operating Expenses. Operating expenses increased by 21.0% to
approximately $18.2 million for the year ended June 30, 1999, as compared to
approximately $15.1 million for the year ended June 30, 1998. This increase is
due primarily to the inclusion of JE's operating expenses of approximately $2.5
million, staff additions and related expenses during the first half of the year
and increased consulting expenses partially offset by the decrease in R&D costs
of $0.7 million. Research and development costs for the year ended June 30, 1999
were $3.6 million, as compared to $4.3 million for the year ended June 30, 1998.
This decrease is due primarily to the completion of the ICC and SHUCS R&D
efforts partially offset by research and development expenses associated with
Astrotech's sounding rocket program.

         Interest Expense. Interest expense was approximately $7.4 million for
the year ended June 30, 1999, as compared with approximately $6.4 million for
the year ended June 30, 1998. The increased interest expense is due primarily to
a full year of interest expense on the $63.3 million of convertible notes as
compared to a partial year in 1998. $2.5 million of interest expense was
capitalized in 1999 as



                                       14
<PAGE>   16
compared to $2.0 million in 1998. Interest is capitalized based primarily on the
construction of the Company's modules and payload processing facilities.

         Interest Income. Interest and other income was approximately $1.6
million and $3.9 million for the years ended June 30, 1999 and 1998,
respectively. This decrease is due primarily to the Company's use of cash for
the purchase of JE and expenditures for property, plant and equipment and debt
payments. Interest income is earned by the Company through the short-term
investment of funds.

         Net Income (Loss) Net Loss. Net loss for the year ended June 30, 1999,
was approximately ($2.6) million, or ($0.23) per share (basic and fully diluted
EPS), on 11,184,742 shares as compared to $9.6 million, or $0.86 per share
(basic EPS), for the year ended June 30, 1998, on 11,154,271 shares and $0.84
per share, fully diluted, on 14,571,278 shares. Income tax expense (benefit) for
these periods was ($0.5) million and $2.5 million for the years ended June 30,
1999 and 1998, respectively. As of June 30, 1999, the Company had approximately
$19.7 million of available net operating loss carry-forwards expiring between
2006 and 2019 to offset future regular taxable income

         The effects of inflation and changing prices have not significantly
impacted the Company's revenue or income from continuing operations during FY
1999 and 1998.

Fiscal Year Ended June 30, 1998 as Compared to the Fiscal Year Ended June 30,
1997

         Revenue. The Company's revenue increased approximately 13% to
approximately $64.1 million for the year ended June 30, 1998 as compared to
$56.6 million for the year ended June 30, 1997. For the year ended June 30,
1998, $39.0 million was recognized from the Mir Contract, $14.3 million from the
REALMS Contract and related commercial customers, and $10.8 million from
Astrotech. Conversely, for the year ended June 30, 1997, $47.1 million was
recognized from the Mir Contract, $8.0 million from the CMAM contract, $4.0
million from the NASDA/ESA contract, and $2.9 million from Astrotech.

         Costs of Revenue. Costs of revenue for the year ended June 30, 1998,
increased 4% to $36.3 million, as compared to $35.0 million for the year ended
June 30, 1997. The primary components of costs of revenue for the year ended
June 30, 1998 are $19.2 million for integration and operation costs under the
Mir Contract, $7.8 million for costs under the REALMS Contract and related
commercial customers, $4.4 million for integrations and operations costs at
Astrotech, and depreciation of $4.9 million. In contrast, the primary costs of
revenue for the year ended June 30, 1997 are, $19.3 million of integration and
operation costs under the Mir Contract, $1.0 million under the CMAM Contract,
$3.6 million under the NASDA/ESA Contract, $1.3 million for integrations and
operations costs at Astrotech, and $9.8 million of depreciation. The decrease in
depreciation expense is attributable to the impact of extending the estimated
useful lives of the Company's modules to 2012. This change in accounting
estimate is treated prospectively and is based on current available information
from NASA, which extends the estimated useful life of the Space Shuttle program
to at least 2012.

         Operating Expenses. Operating expenses increased by 69% to
approximately $15.1 million for the year ended June 30, 1998, as compared to
approximately $8.9 million for the year ended June 30, 1997. This increase is
due primarily to staff additions, adding strength in engineering, design and
research and development capabilities and the inclusion of a full year of
Astrotech's operating expenses as opposed to approximately four months of
expenses in 1997 subsequent to the acquisition. Research and development costs
for the year ended June 30, 1998 were $4.3 million, as compared to $1.7 million
for the year ended June 30, 1997. The increase is due primarily to the Company's
efforts to develop space related assets including the ICC and the SHUCS, which
is being developed to provide reliable and Shuttle-independent data
communication channels that are responsive to payload user requirements.

         Interest Expense. Interest expense was approximately $6.4 million for
the year ended June 30, 1998, as compared with approximately $1.3 million for
the year ended June 30, 1997. The increase in interest expense was due to the
Company's issuance of its Subordinated Convertible Notes due 2007 and interest
costs from the use of a term note. There was also approximately $2.0 million and
$0.3 million of



                                       15
<PAGE>   17
interest capitalized during the year ended June 30, 1998, and year ended June
30, 1997, respectively. Interest is capitalized based primarily on the
construction of the Company's research double module and double module hardware.

         Interest Income. Interest and other income was approximately $3.9
million and $1.8 million for the years ended June 30, 1998 and 1997,
respectively. This increase is due to interest earned by the Company through the
short-term investment of funds raised by the Company's financing activities.

         Net Income. Net income for the year ended June 30, 1998 was
approximately $9.6 million, or $0.86 per share (basic EPS), on 11,154,271 shares
as compared to $13.8 million, or $1.24 per share (basic EPS), for the year ended
June 30, 1997, on 11,118,825 shares. Income tax expense for these periods was
$2.5 million and $3.0 million for the years ended June 30, 1998 and 1997,
respectively. As of June 30, 1998, the Company had approximately $7.9 million of
available net operating loss carry-forwards expiring between 2006 and 2009 to
offset future regular taxable income. Utilization of these net operating loss
carry-forwards may be subject to limitations in the event of significant changes
in the stock ownership of the Company. While there are no restrictions on
transfers or sales of shares of Common Stock that would prevent such a change
from occurring, there is no plan to initiate any such changes on ownership
resulting in the loss of these carry-forwards.

         The effects of inflation and changing prices have not significantly
impacted the Company's revenue or income from continuing operations during FY
1998 and 1997.

LIQUIDITY AND CAPITAL RESOURCES

    The Company has historically financed its capital expenditures, research and
development and working capital requirements with progress payments under its
various contracts, as well as with proceeds received from private debt and
equity offerings and borrowings under credit facilities. During December 1995,
SPACEHAB completed an initial public offering of Common Stock (the "Offering"),
which provided the Company with net proceeds of approximately $43.5 million. In
June 1997, the Company signed an agreement with a financial institution securing
a $10.0 million revolving line of credit (the "Revolving Line of Credit") that
the Company may use for working capital purposes. As of June 30, 1999, no
amounts were drawn on this line of credit that expires in October 1999. In July
1997, Astrotech obtained a five-year term loan (the "Term Loan Agreement"),
which is guaranteed by SPACEHAB, and provides for draws of up to $15.0 million
for general corporate purposes. As of June 30, 1999, the Company had drawn $15.0
million on this loan, $1.0 million of which was drawn in April of 1999, which
had an outstanding balance on that date of $10.1 million. On October 21, 1997,
the Company completed a private placement offering of convertible subordinated
notes (the "Notes Offering"), which provided the Company with net proceeds of
approximately $59.9 million which has been used, in part, for capital
expenditures associated with the development and construction of space related
assets, the purchase of JE, and for general corporate purposes. In December
1998, the Company amended its agreement with Alenia relative to subordinated
notes payable with an outstanding balance of $11.9 million. In exchange for
payment of $4.0 million of principal, Alenia agreed to reduce the annual
interest rate from 12 percent to 10 percent on the outstanding balance as of
January 1, 1999, and the interest payment due for the quarter ended December 31,
1998, was waived resulting in an effective interest rate of 8.75 percent. An
amended agreement with the senior debt holders under the Insurers' note requires
that an interest rate of 8.25 percent be applied to the senior debt with an
outstanding balance of $1.0 million as of June 30, 1999.

   Subsequent to June 30, 1999, DASA agreed to purchase a $12.0 million equity
stake in SPACEHAB. DASA has agreed to purchase 1.33 million shares of preferred
stock, convertible into common shares on a one for one basis, which will
increase DASA's investment interest in SPACEHAB to approximately 11.5 percent.
Under the agreement DASA purchased all of SPACEHAB's 975,000 authorized and
unissued preferred shares. The other 358,334 shares will be issued upon
shareholder approval of a proposal to increase the number of authorized
preferred shares that will be presented at the next shareholders meeting on
October 14, 1999. No dividends are payable on the preferred shares which are
convertible into common shares on a one-for-one basis.



                                       16
<PAGE>   18
    For the period ended June 30, 1999, the Company was in breach of certain
loan covenants of the term loan and line of credit facility. The covenants had
been negotiated prior to the acquisition of JE. While the Company had not drawn
against the line of credit, covenant waivers were requested and received, for
the year ended June 30, 1999, from both lending institutions. The Company
believes it will be in compliance with the covenants on a going forward basis.

         Cash Flows From Operating Activities. Cash provided by (used for)
operations for the years ended June 30, 1999, 1998 and 1997 was ($6.3) million,
$31.6 million and ($6.0) million, respectively. The significant changes between
1999 and 1998 were; the ($2.6) million loss due primarily to the delay in the
ISS assembly and a ($7.8) million change in deferred flight revenue due to the
decrease in progress payments for the missions under the REALMS Contract and
related commercial customers. Progress payments of $11.8 million were recorded
at the end of 1998 for missions STS-95 and STS-96. Those missions flew in 1999.
The reduction of those progress payments was partially offset by progress
payments for STS-107. The significant change between 1998 and 1997 was caused by
the timing of progress payments received by the Company under its contracts.
Under the Mir Contract, the REALMS Contract and the NASDA/ESA Contracts progress
payments are structured such that expenses incurred under these contracts are
billed as costs are incurred.

         Cash Flows Used in Investing Activities. For the years ended June 30,
1999, 1998 and 1997, cash flows used in investing activities were $58.6 million,
$23.1 million and $29.3 million, respectively. Expenditures during the year
ended June 30, 1999 were $24.7 million for the purchase of JE, $27.3 million of
expenditures for the various flight assets including the RDM and ICC system,
$4.2 million for the expansion of both SPACEHAB's payload processing facilities
and Astrotech's payload processing facilities and a $1.4 million investment in
the SpaceDRUMS joint venture. For the years ended June 30, 1998 and 1997, the
major items of investing were for the construction of the RDM, which began in
1997, and the purchase of Astrotech. The Company anticipates that it will spend
approximately $5.7 million in FY 2000, $40.0 million in the aggregate, to
complete the RDM during FY 2000.

         The Company expects to continue funding any additional capital
expenditures and working capital requirements from internally generated cash
flow, draw-downs on existing credit facilities and through future debt and/or
equity offerings.

         Cash Flows From Financing Activities. For the years ended June 30,
1999, 1998 and 1997, cash flows provided by (used for) financing activities were
($6.0) million, $70.9 million and ($2.6) million, respectively. During the year
ended June 1999, the Company made a principal payment of $4.0 million to Alenia,
paid $2.8 million and borrowed an additional $1.0 million under the Term Loan
Agreement. During the year ended June 30, 1998, the Company received net
proceeds of approximately $14.1 million and made payments of $2.1 million under
the Term Loan Agreement. In October 1997, the Company received net proceeds
after commissions and other expenses of approximately $59.9 million by
completing an offering of $55.0 million of its 8 percent Convertible
Subordinated Notes due 2007 as well as the underwriters' exercise of the
over-allotment for an additional $8.3 million for a total of $63.3 million.

         The Company believes that cash flows from the preferred share purchase
by DASA, the Convertible Notes Offering, the Term Loan Agreement, and the
Revolving Line of Credit will be sufficient to meet any cash flow requirements
from operations and other funding requirements for capital asset construction
and development for at least the next twelve months.

RECENT ACCOUNTING PRONOUNCEMENTS

         In 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities" ("SFAS 133").
SFAS 133 becomes effective June 15, 2000 and will require the Company to
disclose additional information on its hedging activities. The Company is
reviewing this standard; however, it is not expected that implementing this
Standard will significantly impact the Company.

YEAR 2000 READINESS DISCLOSURE STATEMENT

         The Year 2000 ("Y2K") issue is the result of computer programs that
were written using two digits rather than four to define the applicable year.
Any computer program that has date-sensitive software may recognize the date
using "00" as the year 1900 rather than the year 2000. This error could result
in systems failures and computational errors causing disruptions of operations,
including, among other things, the temporary inability to process transactions,
send invoices or engage in similar normal business activities.

         SPACEHAB has established a Y2K program to address both
information-technology ("IT") and non-IT problems that may exist within the
SPACEHAB system, including its vendors and customers, e.g.- NASA and the Space
Shuttle. SPACEHAB's Y2K program is divided into five major phases- Awareness and
Risk Assessment, Inventory and Risk Assessment, Repair, Replacement and
Renovation, Verification and Validation, and Implementation and Monitoring.

Phases

         AWARENESS AND RISK ASSESSMENT- This phase is intended to ensure the
establishment of the Y2K program and the awareness of potential risks and
issues. This phase involves communicating the status and progress of the Y2K
program within SPACEHAB and to third parties. SPACEHAB expects that this will be
an on-going activity.

         INVENTORY AND RISK ASSESSMENT- This phase involves taking inventory of
SPACEHAB hardware, software and infrastructure to identify those systems that
are and are not Y2K compatible. The emphasis is on those items, which are
believed by SPACEHAB to have a significant impact on the business from a
financial, legal or service perspective. While this process is ongoing, SPACEHAB
estimates that this phase is substantially complete for Company owned hardware
and software. SPACEHAB is continuing to survey third party vendors to determine
their state of readiness. NASA has informed SPACEHAB that the Space Shuttle, all
onboard systems, shuttle facilities and operations are Y2K compliant.

         REPAIR, REPLACEMENT AND RENOVATION- This phase, also known as
"conversion," is intended to ensure that the appropriate items identified in the
preceding phase are upgraded to meet the Y2K compliance criteria. Material
repairs, replacements and renovations are substantially complete for systems
that are under direct control of SPACEHAB. No assessment of completion dates are
available for those items for which third parties are responsible until the
completion of that portion of the Inventory and Risk Assessment phase.

         VERIFICATION AND VALIDATION- This phase ensures that critical
processes, systems and infrastructure are verified and tested to ensure Y2K
issues will not cause major disruptions in the on-going operations and business
of the Company. Verification and testing of systems under SPACEHAB's direct
control has been substantially completed by SPACEHAB personnel and personnel of
SPACEHAB's major subcontractor, Boeing.

         IMPLEMENTATION AND MONITORING- Y2K upgrades are and will be installed
into SPACEHAB's operating systems as necessary. Monitoring will be employed to
ensure that unforeseen Y2K critical items are appropriately prioritized for
correction. SPACEHAB's implementation and monitoring activities are ongoing.

State of Readiness

         While there is uncertainty inherent in the Y2K problem resulting in
large part from the uncertainty of the readiness of third party vendors,
SPACEHAB's progress towards completing risk assessment within the SPACEHAB
systems is expected to be completed before the end of 1999.

A) Based on an ongoing assessment, the Company has determined that the vast
majority of the hardware and software used in its administrative functions are
Y2K compliant. The computers that are not compliant are being replaced and the
replacement will be completed during 1999.

 B) Some computer hardware used in the operations function of SPACEHAB will
require upgrading. The computers at SPACEHAB's Payload Process Facility in
Florida used for ground support electrical testing ("GSE") are antiquated,
inefficient and are not Y2K compatible. A proposal has been submitted to upgrade
those systems during 1999 and work is progressing on the upgrade.

C) Surveys and/or questionnaires are being sent to those third parties that
might have an impact on SPACEHAB's business to determine their state of
readiness. Those third parties include; NASA, Boeing, Lockheed-Martin and the
various utility service companies serving our locations.

Costs

         The costs associated with required modifications to become Y2K
compliant are not expected to be material to SPACEHAB's financial position or
results of operations. The current estimate to become Y2K compliant is minimal,
approximately $0.2 million, for the replacement of all hardware and software.
This estimate excludes system enhancements, modifications and upgrades to
replace the inefficient and antiquated GSE equipment, which costs are estimated
to be $0.8 million. The costs of the Year 2000 program are being expensed as
incurred. Replacement of the GSE equipment will be capitalized. There was no
specific budget in FY 1999 or for FY 2000 for Y2K costs.

RISKS

         In a likely worse case scenario, the failure to correct a material Y2K
problem could result in an interruption in, or a failure of, certain normal
business activities or operations, including operations that are essential to
the provision of SPACEHAB's services. Due to the general uncertainty inherent
in the Y2K problem, resulting in major part from the state of readiness of
third parties, SPACEHAB is unable to determine at this time whether the
consequences of Y2K failures will have a material impact on SPACEHAB's results
of operations, liquidity or financial condition. Potential Y2K impacts from
third parties include the failure of utility companies and power grids and from
the customer owned IT systems that are located at Astrotech's payload
processing facilities.

Contingency Plans

         After gathering information from SPACEHAB's Y2K readiness program and
to prepare for the possibility that certain information systems or third parties
will not be Y2K compliant, SPACEHAB intends to develop appropriate contingency
plans. Based on third party responses to date, it appears that no significant
systems will be affected by the Y2K issue. The GSE at SPACEHAB's payload
processing facility in Florida, while not Y2K compliant, is still usable. The
only functionality of the GSE that is expected to be impaired is the printing of
the correct date on computer generated reports.

EXPECTATIONS RELATED TO YEAR 2000 ARE FORWARD LOOKING STATEMENTS AND SHOULD BE

INDEPENDENT AUDITORS' REPORT

The Board of Directors
SPACEHAB, Incorporated and Subsidiaries:

         We have audited the accompanying consolidated balance sheets of
SPACEHAB, Incorporated and subsidiaries (the Company) as of June 30, 1999 and
1998, and the related consolidated statements of operations, stockholders'
equity, and cash flows for each of the years in the three-year period ended June
30, 1999. These consolidated financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
consolidated financial statements based on our audits.

         We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

         In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of SPACEHAB,
Incorporated and subsidiaries as of June 30, 1999 and 1998, and the results of
their operations and their cash flows for each of the years in the three-year
period ended June 30, 1999, in conformity with generally accepted accounting
principles.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1)      DESCRIPTION OF THE COMPANY

                SPACEHAB, Incorporated (the Company) is the first company to
         commercially develop, own and operate habitable modules that provide
         space-based laboratory research facilities and cargo services aboard
         the U.S. Space Shuttle system. The Company currently owns and operates
         three pressurized laboratory and logistics supply modules, which
         significantly enhance the capabilities of the Space Shuttle fleet. The
         Company is currently constructing a new research module with associated
         double module hardware. The Company's modules are unique to the Space
         Shuttle fleet.

                To date, the Company has successfully completed thirteen
         missions aboard the Space Shuttle and substantially all of the
         Company's revenue has been generated under contracts with NASA. The
         Company's contracts are subject to periodic funding allocations by
         NASA. NASA's funding is dependent on receiving annual appropriations
         from the United States government. During the years ended June 30,
         1999, 1998 and 1997, approximately 80%, 68% and 88% of the Company's
         revenues were generated under U.S. Government contracts.

                On February 12, 1997, the Company acquired the assets and
         certain of the liabilities of Astrotech Space Operations, L.P.
         ("Astrotech"), a subsidiary of Northrop Grumman, a provider of
         commercial satellite launch processing services and payload processing
         facilities in the United States. These services are provided at the
         Astrotech facilities in Cape Canaveral, Florida and Vandenberg Air
         Force Base in California, and are provided to launch service providers
         on a fixed-price basis. Additionally, Astrotech provides management and
         consulting services to the Boeing Company for its Sea Launch program at
         the Boeing facility in Long Beach, California.

                On July 1, 1998, the Company acquired all of the outstanding
         shares of capital stock of Johnson Engineering Corporation ("JE"). JE
         performs several critical services for NASA including flight crew
         support services, operations, training and fabrication of mockups at
         NASA's Neutral Buoyancy Laboratory and at NASA's Space Vehicle Mockup
         Facility, where astronauts train for both Space Shuttle and ISS
         missions. JE also designs and fabricates flight hardware, such as
         flight crew equipment and crew quarters' habitability outfitting as
         well as providing stowage integration services. JE is also responsible
         for configuration management of the ISS.

(2)      SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         PRINCIPLES OF CONSOLIDATION AND BASIS OF PRESENTATION

                The consolidated financial statements include the accounts of
         SPACEHAB, Incorporated and its wholly owned subsidiaries Astrotech and
         JE. All significant intercompany transactions have been eliminated in
         consolidation.

         CASH AND CASH EQUIVALENTS

                For purposes of its consolidated statements of cash flows, the
         Company considers short-term investments with original maturities of
         three months or less to be cash equivalents. Cash equivalents are
         primarily made up of commercial paper investments recorded at cost,
         which approximates market value.

         PROPERTY AND EQUIPMENT

                Property and equipment are stated at cost. All furniture,
         fixtures and equipment are depreciated using the straight-line method
         over the estimated useful lives of the respective assets,



                                       25
<PAGE>   27
         which is generally five years. The Company's payload processing
         facilities are depreciated using the straight-line method over their
         estimated useful lives ranging from sixteen to forty-three years.

                Through June 30, 1997, the Company's flight modules were
         depreciated over a ten-year period using the straight-line method.
         Effective July 1, 1997, the Company extended the estimated useful lives
         of its space modules through 2012. This change in accounting estimate
         is treated prospectively and was based on then currently available
         information from NASA, which estimated the duration of the Space
         Shuttle program through at least 2012. As a result of this change in
         estimate, the Company's net income increased by $6.2 million for FY
         1998.

                The Company has adopted Statement of Financial Accounting
         Standards No. 121, Accounting for the Impairment of Long-lived Assets
         and for Long-lived Assets to be Disposed Of (Statement 121). Statement
         121 requires that long-lived assets to be held and used, including
         goodwill, be reviewed by the Company for impairment whenever events or
         circumstances indicate that the carrying amount of an asset may not be
         recoverable. An impairment loss is recognized when the undiscounted net
         cash flows associated with the asset are less than the asset's carrying
         amount. Impairment losses, if any, are measured as the excess of the
         carrying amount of the asset over its estimated fair value.

         GOODWILL

                The excess of the cost over the fair value of net tangible and
         identifiable intangible assets acquired in purchase business
         combinations has been assigned to goodwill. Goodwill is being amortized
         on a straight-line basis over twenty to twenty-five years.

         INVESTMENT IN JOINT VENTURES

                  The Company generally uses the equity method of accounting for
         its investments in, and earnings of, investees. In accordance with the
         equity method of accounting, the carrying amount of such an investment
         is initially recorded at cost and is increased to reflect the Company's
         share of the investee's income and is reduced to reflect the Company's
         share of the investee's losses. For those investments for which the
         Company has provided substantially all of the investee's funding, the
         Company uses the modified equity method of accounting whereby 100% of
         the investee's current period earnings or losses are recognized.

         STOCK-BASED COMPENSATION

                The Company has adopted Statement of Financial Accounting
         Standards No. 123, Accounting for Stock-based Compensation (Statement
         123), which encourages, but does not require, the recognition of
         stock-based employee compensation at fair value. The Company has
         elected to continue to account for stock-based employee compensation
         using the intrinsic value method as prescribed in Accounting Principles
         Board Opinion No. 25, Accounting for Stock Issued to Employees, and
         related interpretations. Accordingly, compensation cost for options to
         purchase common stock granted to employees is measured as the excess,
         if any, of the fair value of common stock at the date of the grant over
         the exercise price an employee must pay to acquire the common stock.

                Warrants to purchase common stock granted to other than
         employees as consideration for goods or services rendered are
         recognized at fair value.

         REVENUE RECOGNITION

                Prior to the REALMS contract (note 10), the Company recognized
         revenue upon completion of each module flight. Total contract price was
         allocated to each flight based on the amount of services the Company
         provided on the flight relative to the total services provided for


                                       26
<PAGE>   28
         all flights under contract. Obligations associated with a specific
         mission, e.g., integration services, were also recognized upon
         completion of the mission. Costs directly related to specific missions
         were deferred until the respective missions were completed.

                For all other contract awards for which the capability to
         successfully complete the contract can be reasonably assured and costs
         at completion can be reliably estimated at contract inception, revenue
         recognition under the percentage-of-completion method is being used
         based on costs incurred over the period of the contract. Revenue
         provided by Astrotech's payload processing services is recognized
         ratably over the occupancy period of the satellite while in the
         Astrotech facilities. Revenue provided by JE is primarily based on
         cost-plus award fee contracts, whereby revenue is recognized to the
         extent of costs incurred plus estimates of award fee revenues using the
         percentage-of-completion method. Award fees, which provide earnings
         based on the Company's contract performance as determined by NASA
         evaluations, are recorded when the amounts can be reasonably estimated,
         or are awarded. Changes in estimated costs to complete, provisions for
         contract losses and estimated amounts recognized as award fees are
         recognized in the period they become known.

         RESEARCH AND DEVELOPMENT

                Research and development costs are expensed as incurred.

         INCOME TAXES

                The Company recognizes income taxes under the asset and
         liability method. Under the asset and liability method, deferred tax
         assets and liabilities are recognized for the future tax consequences
         attributable to differences between the financial statement carrying
         amounts of existing assets and liabilities and their respective tax
         bases. Deferred tax assets and liabilities are measured using enacted
         tax rates expected to apply to taxable income in the years in which
         those temporary differences are expected to be recovered or settled.
         The effect on deferred tax assets and liabilities of a change in tax
         rates is recognized in income in the period that includes the enactment
         date.

         NET INCOME (LOSS) PER SHARE

                In December 1997, the Company adopted the provisions of
         Statement of Financial Accounting Standards No. 128, Earnings per
         Share, (Statement 128). Statement 128 supersedes Accounting Principles
         Board Opinion No. 15, Earnings per Share (APB 15) and its related
         interpretations, and promulgates new accounting standards for the
         computation and manner of presentation of the Company's earnings (loss)
         per share. The Company has restated previously reported annual earnings
         per share data in accordance with the provisions of Statement 128 (note
         14). The Company does not believe that the adoption of Statement 128
         had a material impact on the computation or manner of presentation of
         its earnings (loss) per share data as currently or previously presented
         under APB 15.

                Basic earnings (loss) per share are calculated by dividing net
         income (loss) by the weighted average number of common shares
         outstanding during the period.

                The computation of diluted earnings (loss) per share includes
         all common stock options and warrants and other common stock, to the
         extent dilutive, that potentially may be issued as a result of
         conversion privileges, including the convertible subordinated notes
         payable (note 8).

         COMPREHENSIVE INCOME

                During fiscal year 1999, the Company adopted the provisions of
         Statement of Financial Accounting Standards No. 130, Reporting
         Comprehensive Income ("SFAS No. 130"). SFAS No.



                                       27
<PAGE>   29
         130 requires the display of comprehensive income, which includes
         unrealized gains or losses on investments and accumulated foreign
         currency translation adjustments, if any. There were no such components
         of other comprehensive income for the years ended June 30, 1999, 1998
         or 1997.

         ACCOUNTING ESTIMATES

                The preparation of consolidated financial statements in
         conformity with generally accepted accounting principles requires
         management to make estimates and assumptions that affect the reported
         amounts of assets and liabilities and disclosure of contingent assets
         and liabilities at the date of the consolidated financial statements
         and the reported amounts of revenue and expenses during the reported
         periods. Actual results could differ from these estimates.

         RECLASSIFICATIONS

                Certain FY 1997 and 1998 amounts have been reclassified to
         conform to the fiscal 1999 consolidated financial statement
         presentation.

   (3)   STATEMENTS OF CASH FLOWS - SUPPLEMENTAL INFORMATION

                Cash paid for interest costs was approximately $5.4 million,
         $3.4 million and $1.3 million for the years ended June 30, 1999, 1998
         and 1997, respectively. The Company capitalized interest of
         approximately $2.5 million, $2.0 million and $0.3 million during the
         years ended June 30, 1999, 1998 and 1997, respectively, related to the
         module improvements and building in progress.

                The Company paid income taxes of approximately $0.4 million, $19
         thousand and $2.4 million for the years ended June 30, 1999, 1998 and
         1997, respectively.

                During FY 1997, the Company's convertible note payable, with a
         carrying value of approximately $1.2 million, was converted into 75,000
         shares of common stock (note 8).

   (5)   ACQUISITIONS

         JOHNSON ENGINEERING

                On July 1, 1998, the Company paid approximately $24.7 million,
         including transaction costs, to acquire all of the capital stock of JE.
         The business combination has been accounted for using the purchase
         method under Accounting Principles Board Opinion No. 16, Business
         Combinations, (APB Opinion 16). The purchase price has been allocated
         to the assets and liabilities acquired based on estimates of fair value
         as of the date of acquisition. Based on the allocation of the net
         assets acquired, goodwill of approximately $23.4 million was recorded.
         Such goodwill is being amortized on a straight-line basis over 25
         years. The purchase price has been allocated as follows (in thousands):

         ASTROTECH

                  The Company paid $20.1 million, including transaction costs,
         to acquire substantially all of the assets and certain of the
         liabilities of Astrotech. The purchase was effective on February 12,
         1997. The business combination was accounted for using the purchase
         method. The purchase price was allocated to the assets and liabilities
         acquired based on estimates of fair value as of the date of
         acquisition. Based on the allocation of the net assets acquired,
         goodwill of approximately $3.5 million was recorded and is being
         amortized on a straight line basis over twenty years.

   (6)   LOANS PAYABLE UNDER CREDIT AGREEMENT

                Prior to an August 1996 amendment, the Company's credit
         agreement consisted of a $6.5 million term loan bearing interest at 1
         percent per month and a $5.5 million non-interest-bearing term loan
         with several insurance companies. In addition, a revolving credit
         commitment with a subcontractor and former shareholder provided a
         maximum outstanding balance of $6.0 million and bore interest at a rate
         of 1 percent per month.

                In August 1996, the Company's credit agreement was amended.
         Under the amendment, the revolving credit commitment with a
         subcontractor and former shareholder was canceled. In exchange for the
         full satisfaction of the Company's term loans with the various
         insurance companies, the Company paid the insurance companies $2.5
         million and agreed to pay an additional $2.0 million under a new
         non-interest-bearing term loan. As of June 30, 1999, the remaining
         balance due under the term loan is due in installments of $0.33 million
         on each of August 1, 1999, 2000 and 2001. As a result of this amended
         and restated agreement, the Company recognized an extraordinary gain of
         $3.3 million, net of income taxes and other related expenses of $0.8
         million and $0.1 million, respectively, during the year ended June 30,
         1997.

                In conjunction with a payment of certain principal of notes
         payable due to Alenia Spazio S.p.A. in December 1998, see note 7, the
         annual interest rate on the outstanding balances was amended to be at
         8.25 percent per year. Aggregate interest cost incurred on the debts
         due under the various credit agreements was approximately $40 thousand
         , $0 and $0.1 million for the years ended June 30, 1999, 1998 and 1997
         respectively.

   (7)   NOTES PAYABLE TO SHAREHOLDER

                The Company issued subordinated notes for a portion of the
         amount due to Alenia Spazio S.p.A. (Alenia), a shareholder, under a
         previously completed construction contract for the Company's flight
         modules. In December 1998, the Company amended its agreement with
         Alenia Spazio S.p.A. relative to the subordinated notes payable with an
         outstanding principal balance of $11.9 million due in August 2001. In
         exchange for payment of $4.0 million of principal, Alenia agreed to
         waive the interest payment due for the quarter ended December 31, 1998
         and to reduce



                                       30
<PAGE>   32
         the annual interest rate on the subordinated notes from 12 to 10
         percent on the outstanding balance as of January 1, 1999. In addition,
         Alenia may elect to convert, in whole or part, the remaining principal
         amount into SPACEHAB equity, on terms and conditions to be agreed with
         SPACEHAB.

                The subordinated notes had aggregate outstanding balances of
         $7.9 million and $11.9 million at June 30, 1999 and 1998, respectively.
         The notes currently bear interest at an annual rate of 10 percent. No
         amount of principal or accrued interest on the notes is due until all
         amounts under the amended and restated credit agreement due to the
         various insurance companies (note 6) are repaid. As such, all principal
         payments are due under these notes on August 1, 2001. However, during
         fiscal 1998, the Company began paying interest quarterly. The Company
         paid $0.4 million of interest during the year ended June 30, 1999 and
         intends to continue to pay interest quarterly.

                Interest cost converted to additional principal on the notes to
         Alenia was approximately $0 and $0.7 million for the years ended June
         30, 1999 and 1998, respectively.

   (8)   OTHER LONG-TERM DEBT

         CONVERTIBLE NOTE PAYABLE

                On August 12, 1992, the Company issued a subordinated promissory
         note to an investment bank in the amount of $0.9 million, carrying
         interest at LIBOR plus 3 percent, and maturing six months after the
         payment of all other indebtedness due under the amended and restated
         credit agreement and the subordinated notes to Alenia. The note was
         convertible at the option of the holder into 75,000 shares of the
         Company's common stock at any time prior to maturity. On October 25,
         1996, the investment bank exercised its option to convert the note into
         the Company's common stock.

         CREDIT FACILITIES

                On June 16, 1997, the Company entered into a $10.0 million line
         of credit agreement with a financial institution. Outstanding balances
         on the line of credit accrue interest at either the lender's prime rate
         or a LIBOR-based rate. Certain assets of the Company collateralize this
         loan. The term of the agreement is through October 1999. Through June
         30, 1999, the Company has not drawn against the line of credit.

                On July 14, 1997, the Company's subsidiary, Astrotech, entered
         into another credit facility for loans of up to $15.0 million with a
         financial institution. The term of the agreement is through July 13,
         2002. This loan is collateralized by the assets of Astrotech and
         certain other assets of the Company, and is guaranteed by the Company.
         Interest accrues at LIBOR plus three percent. Principal and interest
         are payable on a quarterly basis. In April 1999, the Company borrowed
         an additional $1.0 million under this credit facility with the same
         terms, conditions and expiration date of the original loan. Principal
         payments of $3.1 million are due in FY 2000, 2001, and 2002 and
         principal payments of $0.8 million are due in FY 2003. At June 30,
         1999, the Company had an outstanding balance of $10.2 million under
         this credit facility and accrued interest of $0.2 million.

         COVENANT CHANGES

                For the period ended June 30, 1999, the Company was in breach of
         certain loan covenants of the term loan and line of credit facility.
         The covenants had been negotiated prior to the acquisition of JE. While
         the Company had not drawn against the line of credit, covenant waivers
         were requested and received, for the year ended June 30, 1999, from
         both lending institutions. The Company believes it will be in
         compliance with the covenants on a going forward basis.

         CONVERTIBLE SUBORDINATED NOTES

                In October 1997, the Company completed a private placement
         offering for $63.3 million of aggregate principal of unsecured 8
         percent Convertible Subordinated Notes due 2007. Interest is payable
         semi-annually. The notes are convertible into the common stock of the
         Company at a rate of $13.625 per share. This offering provided the
         Company with net proceeds of approximately $59.9 million to be used for
         capital expenditures associated with the development and construction
         of space related assets and for other general corporate purposes.

   (9)   FAIR VALUE OF FINANCIAL INSTRUMENTS

                The following table presents the carrying amounts and estimated
         fair values of the Company's financial instruments as of June 30, 1999
         and 1998 in accordance with Statement of Financial Accounting Standards
         No. 107, Disclosures about Fair Value of Financial Instruments (in

         The fair value of the Company's long-term debt is based on quoted
         market price or is estimated based on the current rates offered to the
         Company for debt of similar remaining maturities and other terms. The
         carrying amounts of cash and cash equivalents, receivables, and
         accounts payable and accrued expenses approximate their fair market
         value because of the relatively short duration of these instruments.

  (10)   NASA CONTRACTS

         MIR SPACE STATION CONTRACT

                On July 14, 1995, NASA and the Company completed final
         negotiations to provide the Company's flight modules and related
         integration services over four missions to the Russian Space Station
         Mir. The contract was subsequently amended which resulted in a total
         contract value of $91.5 million and the addition of three missions.

                During the years ended June 30, 1998 and 1997, the Company
         recognized $39.0 million and $41.7 million, respectively, of revenue
         under the Mir contract. Work under the Mir contract, as amended, was
         completed with its final mission in June 1998.

         RESEARCH AND LOGISTICS MODULE SERVICES CONTRACT

                On December 21, 1997, the Company entered into the Research and
         Logistics Module Services (REALMS) Contract to provide to NASA its
         flight modules and related integration services over three missions at
         an aggregate fixed price of $44.9 million. This contract provides for
         NASA to use the flight modules for both science and logistics missions.
         During 1999, NASA


                                       32
<PAGE>   34
         exercised an additional option mission and change orders thereby
         increasing the contract value to $68.2 million.

                During the years ended June 30, 1999 and 1998, the Company
         recognized $28.2 million and $14.3 million of revenue, respectively,
         under this contract.

         FLIGHT CREW SYSTEMS DEVELOPMENT CONTRACT ("FCSD")

                JE primarily operates under NASA's FCSD Contract which is
         currently a $326.3 million multi task cost plus-award and incentive fee
         contract. The contract commenced in May 1993 and will conclude in April
         2001. NASA has the option to exercise a one year extension. JE performs
         several critical services for NASA including flight crew support
         services, operations, training and fabrication of mockups at NASA's
         Neutral Buoyancy Laboratory and at NASA's Space Vehicle Mockup
         Facility, where astronauts train for both Space Shuttle and ISS
         missions. JE also designs and fabricates flight hardware, such as
         flight crew equipment and crew quarters habitability outfitting as well
         as providing stowage integration services. JE is also responsible for
         configuration management of the ISS.

  (11)   STOCKHOLDER RIGHTS PLAN

                On March 26, 1999, the Board of Directors adopted a Stockholder
         Rights Plan designed to deter coercive takeover tactics and to prevent
         a potential acquirer from gaining control of the Company without
         offering a fair price to all of the Company's stockholders. A dividend
         of one preferred share purchase right (a "Right") was declared on every
         share of Common Stock outstanding on April 9, 1999. Each Right under
         the Plan entitles the holder to buy one one-thousandth of a share of a
         new series of junior participating preferred stock for $35. If any
         person or group becomes the beneficial owner of 15 percent or more of
         common stock (with certain limited exceptions), then each Right (not
         owned by the 15 percent stockholder) will then entitle its holder to
         purchase, at the Right's then current exercise price, common shares
         having a market value of twice the exercise price. In addition, if
         after any person has become a 15 percent stockholder, and is involved
         in a merger or other business combination transaction with another
         person, each Right will entitle its holder (other than the 15 percent
         stockholder) to purchase, at the Right's then current exercise price,
         common shares of the acquiring company having a value of twice the
         Right's then current exercise price. The rights were granted to each
         shareholder of record on April 9, 1999. At any time before a person or
         group acquires a 15% position, SPACEHAB generally will be entitled to
         redeem the Rights at a redemption price of $0.01 per Right. The Rights
         will expire on April 9, 2009.

(12)     COMMON STOCK OPTION AND STOCK PURCHASE PLANS

         NON-QUALIFIED OPTIONS

                Non-qualified options are granted at the sole discretion of the
         Board of directors. Prior to the adoption of the 1994 Stock Incentive
         Plan (the 1994 Plan), stock options granted to the Company's officers
         and employees were part of their employment contract or offer. The
         number and price of the options granted was defined in the employment
         agreements and such options vest incrementally over a period of four
         years and generally expire within ten years of the date of grant.
         300,000 options were granted in fiscal year 1999 in connection with the
         acquisition of JE.

         THE 1994 PLAN

                Under the terms of the 1994 Plan, the number and price of the
         options granted to employees is determined by the Board of Directors
         and such options vest, in most cases, incrementally over a period of
         four years and expire no more than ten years after the date of grant.


                                       33
<PAGE>   35
         THE DIRECTORS' STOCK OPTION PLAN

                Prior to an amendment on October 21, 1997, each nonemployee
         member of the Board of Directors was annually granted options to
         purchase 5,000 shares of common stock at exercise prices equal to the
         fair market value on the date of grant. Subsequent to the amendment,
         each nonemployee member of the Board of Directors received a one-time
         grant of an option to purchase 10,000 shares of common stock. Further,
         each new nonemployee director after the amendment date shall receive a
         one-time grant of an option to purchase 10,000 shares. In addition,
         effective as of the date of each annual meeting of the Company's
         stockholders on or after the effective date, each nonemployee director
         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. Options under the Director's Plan vest after one year and
         expire seven years from the date of grant.

         1997 EMPLOYEE STOCK PURCHASE PLAN

                During the year ended June 30, 1998, the Company adopted an
         employee stock purchase plan that permits eligible employees to
         purchase shares of common stock of the Company at prices no less than
         85 percent of the current market price. Eligible employees may elect to
         participate in the plan by authorizing payroll deductions from one
         percent to ten percent of gross compensation for each payroll period.
         On the last day of each quarter, each participant's contribution
         account is used to purchase the maximum number of whole and fractional
         shares of common stock determined by dividing the contribution
         account's balance by the lesser of 85 percent of the price of a share
         of common stock on the first day of the quarter or the last day of a
         quarter. The maximum number of shares of common stock that may be
         purchased under the plan is 1,500,000. Through June 30, 1999, 73,614
         shares have been issued under the plan.

                The Company applies APB Opinion 25 and related interpretations
         in accounting for its plans. Accordingly, as all options have been
         granted at exercise prices equal to the fair market value as of the
         date of grant, no compensation cost has been recognized under these
         plans in the accompanying consolidated financial statements. Had
         compensation cost been determined consistent with Statement 123, the
         Company's net income and earnings per common share would have been
         reduced to the pro forma amounts indicated below (in thousands, except
         per share data):

                The fair value of each option granted is estimated on the date
         of grant using the Black-Scholes option-pricing model with the
         following weighted average assumptions used for grants in fiscal years
         1999, 1998 and 1997, respectively: 0.0 percent dividend growth;
         expected volatility ranging from 35 percent to 40 percent; risk-free
         interest rates ranging from 5.68 percent to 6.71 percent; and expected
         lives ranging from three to seven years.

                The effects of compensation cost as determined under Statement
         123 on net income in fiscal years 1999, 1998 and 1997 may not be
         representative of the effects on pro forma net income in future
         periods.

WARRANTS

                The Company also has 53,000 currently exercisable warrants
         outstanding to purchase the Company's common stock at $9.00 per share,
         with an expiration date of June 2002. The fair market value of these
         warrants was recognized at issuance. All such warrants were issued at
         exercise prices equivalent to, or in excess of, the determined fair
         market value of the Company's common stock at the date of issuance.

                As of June 30, 1998, current deferred tax assets of $151,000 are
         included in prepaid expenses and other current assets in the
         accompanying balance sheet.

                The net changes in the total valuation allowance for the years
         ended June 30, 1999, 1998 and 1997 were an increase of $0.2 million and
         decreases of $4.7 million and $2.1 million, respectively.

                At June 30, 1999, the Company had accumulated net operating
         losses of $19.7 million available to offset future regular taxable
         income. These operating loss carryforwards expire between the years
         2007 and 2019. Utilization of these net operating losses may be subject
         to limitations in the event of significant changes in stock ownership
         of the Company.

               Additionally, the Company has approximately $2.2 million and $3.3
         million of research and experimentation and alternative minimum tax
         credit carryforwards, respectively, available to offset future regular
         tax liabilities. The research and experimentation credits expire
         between the years 2000 and 2008; the alternative minimum tax credits
         carryforward indefinitely.

                In assessing the realizability of deferred tax assets,
         management considers whether it is more likely than not that some
         portion or all of the deferred tax assets are realizable. Management
         considers the scheduled reversal of deferred tax liabilities, projected
         future taxable income, and tax planning strategies in making this
         assessment. Based upon the level of projected future regular taxable
         income over the periods, which the deferred tax assets are deductible,
         management believes that the Company will realize the benefits of these
         deductions. As of June 30, 1999, the Company provided a valuation
         allowance of $169 thousand against deferred tax assets. The amount of
         the deferred tax assets considered realizable, however, could be
         reduced if estimates of future regular taxable income during the
         carryforward period are reduced.

  (14)   NET INCOME (LOSS) PER SHARE

                In December 1997, the Company adopted the provisions of
         Statement of Financial Accounting Standards (SFAS) No. 128, Earnings
         Per Share, which established new guidelines for the calculations of
         earnings (loss) per share. Earnings (loss) per share for all prior
         periods have been restated to reflect the provisions of this Statement.

                The following are reconciliations of the numerators and
         denominators of the basic and diluted earnings (loss) per share
         computations for "income (loss) before extraordinary item" and
         "extraordinary item" for the years ended June 30, 1999, 1998 and 1997

                Options and warrants to purchase 899,131 and 792,361 shares of
         common stock, at prices ranging from $7.50 to $24.00 per share were
         outstanding for the years ended June 30, 1998 and 1997, respectively.
         These were not included in the computations of diluted earnings per
         share because the options' and warrants' exercise prices were greater
         than the average market price of the common shares during the years
         ended June 30, 1998 and 1997.

                All options and warrants to purchase shares of common stock were
         excluded from the computations of diluted earnings (loss) per share for
         the year ended June 30, 1999, because the impact of such options and
         warrants is anti-dilutive.



  (15)   EMPLOYEE BENEFIT PLAN

                The Company has a defined contribution retirement plan, which
         covers all employees and officers. For the years ended June 30, 1999,
         1998 and 1997, the Company contributed $0.8 million, $0.1 million and
         $0.1 million, respectively, to the plan. The Company has the right, but
         not the obligation, to make contributions to the plan in future years
         at the discretion of the Company's Board of Directors.

  (16)   COMMITMENTS

         INTEGRATION AND OPERATIONS CONTRACTS

                On August 13, 1997, the Company initiated a letter agreement
         with The Boeing Company, a major subcontractor, for standard
         integration and operation services to the Company for future missions
         that were not already provided for under its contract for missions to
         the Mir Space Station. In August 1998, this letter agreement became a
         cost plus incentive fee contract whereby Boeing will provide
         integration and operations services required to successfully complete
         four research missions (one single module mission and three double
         module missions) and five logistics double module missions.
         Additionally, there are several tasks that are separately priced to
         yield a contract value of up to $42.3 million. As of June 30, 1999,
         $16.2 million has been incurred under this commitment.

         MODULE CONSTRUCTION CONTRACTS

                During fiscal year 1997, the Company entered into a $36.8
         million cost-plus-fee contract with Boeing to construct a new research
         module with associated double module hardware. The Company has taken
         initial delivery of the module and is in the process of completing its
         construction which is expected to be completed in the middle of fiscal
         year 2000. The Company has incurred approximately $32.9 million in
         construction costs through June 30, 1999.

                During FY 1999, the Company entered into a $4.6 million letter
         agreement with Boeing to initiate activities to support the fabrication
         of a double docking module. The letter contract period of performance
         is through August 1999. The Company plans to extend the letter
         agreement. The Company has incurred $1.0 million in costs through June
         30, 1999.

         JOINT VENTURE

                During June 1998, the Company entered into a joint venture
         agreement with Guigne Technologies Limited for the purpose of
         developing, fabricating, marketing and sales of SpaceDRUMS(TM)
         services. In accordance with the joint venture agreement, the Company
         has agreed to contribute, in exchange for a 50 percent interest in
         SpaceDRUMS(TM), an aggregate of $2.0 million of working capital to the
         joint venture at varying dates and amounts through October 1999. The
         Company's contributions will be in the form of an unsecured
         non-interest bearing note. Through June 30, 1999, the Company has made
         contributions of $1.4 million to the joint venture. During 1999, the
         joint venture entered into a $5.0 million contract with the Colorado
         School of Mines for the lease of the SpaceDRUMS(TM) facility.

                The Company does not have the ability to exclusively control the
         operational and financial policies of SpaceDRUMS, although the Company
         does exert significant influence and as such is recognizing its
         investment in SpaceDRUMS using the modified equity method of
         accounting. During the year ended June 30, 1999, SpaceDRUMS had no
         revenues and generated a net loss of approximately $0.001 million of
         which the Company recognized its proportionate share. SpaceDRUMS has
         total assets, total liabilities and total equity as of June 30, 1999:
         $3.7 million, $2.3 million and $1.4 million respectively. The carrying
         value of the investment in SpaceDRUMS is $1.4 million as of June 30,
         1999.

         LEASES

                The Company is obligated under capital leases for equipment and
         noncancelable operating leases for equipment, office space, storage
         space, and the land for a payload processing facility. Future minimum
         payments under these capital leases and noncancelable operating leases
         are as follows (in thousands):

                Rent expense for the years ended June 30, 1999, 1998 and 1997,

         respectively.

(17)     SEGMENT INFORMATION

                  The Company adopted SFAS No. 131, "Disclosure about Segments
         of an Enterprise and Related Information", as of June 30, 1999. SFAS
         No. 131 establishes annual and interim reporting standards for an
         enterprise's operating segments.

                  Based on its organization, the Company operates in three
         business segments; Astrotech, JE and SPACEHAB. Astrotech, acquired in
         February 1997, provides payload processing facilities to serve the
         satellite manufacturing and launch services industry. Astrotech
         currently provides launch site preparation of flight ready satellites
         to major U.S. space launch companies and satellite manufacturers. JE,
         acquired in July 1998, is primarily engaged in providing engineering
         services and products to the Federal Government and NASA, primarily
         under the Flight Crew Systems Development Contract (FCSD). SPACEHAB was
         founded to commercially develop space habitat modules to operate in the
         cargo bay of the Space Shuttles. SPACEHAB provides access to the
         modules and integration and integration and operations support services
         for both NASA and commercial customers.

                 The Company's chief operating decision maker utilizes both
         revenue and income before taxes, including allocated interest based on
         the investment in the segment, in assessing performance and making
         overall operating decisions and resource allocations. As such, other
         income/expense items including taxes and corporate overhead have not

                             SPACEHAB, INCORPORATED


                            1994 STOCK INCENTIVE PLAN
              (as amended and restated effective October 14, 1999)

                            1994 STOCK INCENTIVE PLAN
              (as amended and restated effective October 14, 1999)

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. Awards 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:

                                       1
<PAGE>   3
                           (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;

                           (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

                                       2
<PAGE>   4
                           (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 3,950,000 (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 assets, recapitalization, Stock
dividend, Stock split, spin-off, split-up, split-off, distribution of assets or
other change in corporate 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

                                       3
<PAGE>   5
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.

                           (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

                                       4
<PAGE>   6
Stock Option which are paid for using Restricted Stock or Performance Shares
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 provision 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.

                                       5
<PAGE>   7
                  7.2. The Committee may provide that a Stock Appreciation Right
may be exercised only within a 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 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, on 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 forefeiture, 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.

                                       6
<PAGE>   8
SECTION 9.             PERFORMANCE SHARES 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 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, his or her Performance Share award shall be forfeited.

                           (e) 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.

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 any 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,

                                       7
<PAGE>   9
any security for the loan, the terms on which the loan is to be repaid and the
conditions, if any, under 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.

                                       8
<PAGE>   10
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 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

                                       9
<PAGE>   11
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 any 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.

shareholders.

                    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

                  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.

                           (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.

                  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

                  5.       Reimbursement of Expenses

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,

                  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

                  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

                  THIS AGREEMENT SHALL BE GOVERNED BY, CONSTRUED, APPLIED AND
ENFORCED IN ACCORDANCE WITH THE LAWS OF THE DISTRICT OF COLUMBIA, EXCEPT THAT NO
DOCTRINE OF CHOICE OF LAW SHALL BE USED TO APPLY ANY LAW OTHER THAN THAT OF

                    EMPLOYMENT AND NON-INTERFERENCE AGREEMENT

                  This Employment and Non-Interference Agreement (this
"Agreement"), is dated as of March 1, 1999, by and between Michael E. Kearney
(the "Executive") and SPACEHAB, Incorporated, a Washington state 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, Marketing and Sales, and to
undertake such duties and responsibilities as may be reasonably assigned to
Executive from time to time by 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.

                  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
<PAGE>   2
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 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 within 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:

                           (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)

                                       3
<PAGE>   4
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) 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

                                       4
<PAGE>   5
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.

                  (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 $188,000 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 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 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

                  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

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.

and, as required, facilities, equipment and material necessary for accomplishing
this support function. These requirements apply to all current and future
programs involving the Flight Crew Support Division of the Johnson Space Center.

                  The activities to be supported are located at and near the
NASA Johnson Space Center (JSC) in Houston, Texas, and at the Marshall Space
Flight Center in Huntsville, Alabama. Technical support activities are currently
performed in the following JSC buildings: J9A/J9B, Mockup and Integration
Laboratory; J29, Weightless Environment Training Facility, Anthropometric and
Biomechanics Laboratory; J32E/J32T, Mockup and Trainer Support Shop; J220,
Mockup Assembly and Support Area; J15, Optics and 70mm Camera Laboratory,
Engineering Design Support Laboratory, Electronic Still Camera Laboratory, Laser
Anthropometric Mapping System Facility, Computer Facility, Graphics Analysis
Facility, Remote Operation Interaction Laboratory; J17, Hygiene and Housekeeping
Systems Development Laboratory, Tools and Diagnostics Laboratory, Small Format
Camera Laboratory, Human Computer Interaction Laboratory, Food Systems
Engineering Facility. Some engineering and management support personnel are
currently housed onsite. Offsite facilities may be required for support
activities consisting of technical interchange, planning and management
activities, research planning, performance and analysis, project management,
design/drafting, Crew Compartment Configuration Drawing production and archival,
Decal Laboratory and Lighting Laboratory operations, warehousing for temporary
storage of mockups and training articles, and secured (bonded) storage for
flight hardware components and materials and mission logistics hardware
complements. Federal Information Processing (FIP) resources and users requiring
support are located in all of these buildings and facilities. Technical support
activities performed at the Marshall Space Flight Center will be housed onsite
at that installation.

         Maintenance/repair of SFE that was designed and built by SHI will be
         the responsibility of SHI. Boeing shall be responsible to report
         hardware failures immediately to SHI via Material Review Record (MRR).
         To do this, Boeing will perform trouble shooting to locate problem to,
         but not within, the SFE component. Boeing support to SHI for trouble
         shooting within the SFE component and shipping or repairing the
         component will be authorized by task directive and is funded under the
         Studies/Services element of the statement of work (Reference Article 4

Article 15 - Exchange of Technical Information

During the term of this Contract, SHI and MDC, to the extent of their right to
do so, agree to exchange all such technical and management information as may
reasonably be required for each to perform its obligations hereunder. To the
extent that proprietary information of either party is disclosed, such
information or data which is (i) submitted in writing, must be designated by an
appropriate stamp, marking or legend thereon to be of proprietary or
confidential nature, or (ii) orally submitted, must be identified as proprietary
or confidential prior to disclosure and the disclosing party notifies the
receiving party, in writing, specifically identifying any such proprietary or
confidential information so orally submitted within thirty days after such oral
submission. Notwithstanding termination or expiration of this Contract, each
party will keep in confidence and prevent the disclosure of all such proprietary
information and data, whether technical or commercial, to any third party.
Neither party shall be liable for disclosure of any such proprietary information
or data, if such information:

A.       Was in the public domain at the time it was disclosed, or later becomes
         part of the public domain other than throughout the action of the party
         receiving it; or

B.       Was known to the party receiving it at the time of disclosure; or

C.       Is disclosed with the prior written approval of the other party; or

D.       Is disclosed by the party providing the same, to others, on a
         non-restricted basis; or

E.       Is disclosed inadvertently despite the exercise of the same degree of
         care that the receiving party takes to preserve or safeguard its own
         proprietary information; or

F.       Becomes known to the receiving party from a source other than the
         disclosing party without breach of this Section by the receiving party;
         or

G.       Is disclosed one (1) year after expiration or termination of this
         Contract; or

H.       Is disclosed to a government agency for certification or export license
         purposes, taking all reasonable precautions to prevent further
         disclosure by such agency.

Article 16 - Excusable Delays

                                       6
<PAGE>   10
Except for default of subcontractors at any tier, MDC shall not be in default
because of any failure to perform this Contract under its terms if the failure
arises from causes beyond the control and without the fault or negligence of
MDC. Examples of these causes include but are not limited to are (1) acts of God
or of the public enemy, (2) acts of Government in either its sovereign or
contractual capacity, (3) fires, (4) floods, (5) epidemics, (6) quarantine
restrictions, (7) strikes, (8) freight embargoes, and (9) unusually severe
weather. In each instance, the failure to perform must be beyond the control and
without the fault or negligence of MDC. "Default" includes failure to make
progress in the work so as to endanger performance.

MDC shall not be in default, if the failure to perform is caused by the failure
of a subcontractor at any tier to perform or make progress, and if the cause of
the failure was beyond the control of both MDC and subcontractor, and without
fault or negligence of either, unless (1) MDC knew of other sources to obtain
the subcontracted supplies or services from to meet schedule; (2) SHI ordered
MDC in writing to purchase these supplies or services from the other source; and
(3) MDC failed to comply reasonably with this order.

If SHI determined that any failure to perform results from one or more of the
causes above, the delivery schedule shall be revised, subject to the rights of
SHI under the Termination Clause of this Contract.

Article 17 - Changes

A.       SHI may at any time, by written order, and with such concurrence to not
         be unreasonably withheld from MDC, make changes within the general
         scope of this Contract in any one or more of the following:

         (1)      Description of services to be performed.

         (2)      Time of performance (i.e., hours of the day, days of the week,
                  etc.).

         (3)      Place of performance of the services.

         (4)      Drawings, designs, or specifications.

         (5)      Method of shipment or packing of supplies.

         (6)      Place of delivery.

         (7)      Types and amounts of SHI and/or Government-Furnished Property
                  to be provided.

B.       If any such change causes an increase or decrease in the estimated cost
         of, or the time required for, performance of any part of the work under
         this contract, whether or not changed by the order, or otherwise
         affects any other terms and conditions of this contract, SHI shall make
         an equitable adjustment in the (1) estimated cost, delivery or
         completion schedule, or both; (2) amount of fee; and (3) other affected
         terms and shall modify the contract accordingly.

C.       MDC shall assert its right to an adjustment under this clause within 60
         days from the date of receipt of the written order. However, if SHI
         decides that the facts justify it, SHI may receive and act upon a
         proposal submitted before final payment of the contract.

D.       Failure to agree to any adjustment shall be a dispute under the
         Disputes Clause. However, nothing in this clause shall excuse MDC from
         proceeding with the contract as changed.

E.       Notwithstanding the terms and conditions of paragraphs (a) and (b)
         above, the estimated cost of this contract and, if this contract is
         incrementally funded, the funds allotted for the performance of this
         contract, shall not be increased or considered to be increased except
         by specific written modification of the contract indicating the new
         contract estimated cost and, if this contract is incrementally funded,
         the new amount allotted to the contract. Until this modification is
         made,

                                       7
<PAGE>   11
         MDC shall not be obligated to continue performance or incur costs
         beyond the point established in the Limitation of Funds Clause of this
         Contract.

changed in any manner except by an instrument in writing hereto, executed by
both parties acting through their duly authorized representatives.

part, of the work called for by this contract for a period of up to 90 days
after the order is delivered to MDC, and for any further period to which the
parties may agree. The order shall be specifically identified as a stop-work

comply with its terms and take all reasonable steps to minimize the incurrence
of costs allocable to the work covered by the order during the period of work
stoppage.

         conduct such negotiations and defense without expense or liability to
         SHI as provided under Paragraph A. above.

                       AMENDED AND RESTATED EMPLOYMENT AND

                           NON-INTERFERENCE AGREEMENT


                  This Employment and Non-Interference Agreement (this
"Agreement"), is dated as of April 1, 1997 (the "Effective Date") and amended on
January 15, 1998 and January 15, 1999 by and between Dr. Shelley A. Harrison
(the "Executive") and SPACEHAB, Incorporated, a Washington corporation (the
"Company").


                              W I T N E S S E T H:

                  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 Chief Executive Officer of the Company and to
undertake such duties and responsibilities as may be reasonably assigned to
Executive from time to time by the Board of Directors of the Company, provided
however, that nothing herein shall require Executive to relocate his principal
residence from the Long Island, New York area.

         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 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.
<PAGE>   2
                  (b) During the Term of Employment, Executive shall devote such
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, provided however, that the Company acknowledges that Employee is a
General Partner in several venture capital funds and is a director, consultant
and/or advisor to certain companies and associations. The Company specifically
agrees that such current and future activities of the same general type and
scope are permitted under the terms of this Agreement and are not in derogation
of Employee's duties and obligations under this Agreement.

                  (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
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 the Effective
Date and shall continue for a term ending on March 31, 2002 (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 within ninety (90) days prior to the end of the
Initial Term or an Additional Term, as the case may be. Should Executive's
employment by the Company be earlier terminated pursuant to Section 3(b) or
3(c), 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

                                       2
<PAGE>   3
                  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:

                           (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 compensation or 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 for any proposal that would require the relocation of
                  Executive from the Long Island, New York area; provided,
                  however, that in the event the Executive's employment is
                  terminated following a Change in Control, the Executive shall
                  serve the Company as a consultant under the terms of the
                  Consulting and Non-Competition Agreement between the Executive
                  and the Company dated

                  Agreement"); 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.

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) [by the Company for any other reason or no reason] or

                  reduction], the Company will: (A) provide to the Executive all
                  payments, rights and benefits due as of the date of
                  termination under the terms of the Company's employee and

                  of termination, any earned but unpaid annual bonus for any
                  completed fiscal year, a pro rata portion of the annual bonus
                  for the year in which the termination occurs (determined by
                  multiplying the target annual bonus for the year of
                  termination by a fraction the numerator of which is the number
                  of days in the calendar year that precede the date of
                  termination and the denominator of which is 365), and any
                  unreimbursed business expenses or other amounts due to the

                  the Executive would be entitled to under Sections 4(a) and
                  4(b) for the period from effectiveness of termination through
                  the thirtieth month anniversary of termination; and (C) pay to
                  Executive (or his estate or representative) the benefits
                  described in Section 6 through the thirtieth month anniversary

                           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(h) and
                  Sections 8 and 9. If the Company makes the payments required

                  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 pay and provide to the Executive any Accrued
                  Rights and the Company will not be obligated to pay any
                  further amounts to Executive under this Agreement.

                           (iii) Notwithstanding the provisions of paragraphs

                  terminated following a Change in Control pursuant to Section
                  3(b)(v) [by the Company for any other reason or no reason] or

                  then-current base salary and (2) the average of the last three
                  annual bonuses paid to the Executive; and (C) pay to Executive
                  (or his estate or representative) the benefits described in
                  Section 6 through the thirty-sixth month anniversary of
                  termination.

                           If the Company makes the payments required by this

                  termination, other than any amounts under the Consulting and
                  Non-Competition 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),
Executive shall not be under a duty to seek to obtain alternative employment;
and if Executive thereafter obtains alternative employment, the Company's
payment obligations under Section 3(d), including its obligation to provide
insurance coverage, if any, will not be mitigated or reduced by Executive's
compensation under such alternative employment.

Company is obligated to make payments pursuant to Section 3(d), 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, other than

termination of employment, unless such termination is pursuant to Sections
3(b)(iii) of (iv) or 3(c)(iv) hereof.

                  (h) Termination of the Term of Employment will not terminate

                  7.       Parachute Tax Indemnity

                  (a) If it shall be determined that any amount paid,
distributed or treated as paid or distributed by the Company to or for the
Executive's benefit (whether paid or payable or distributed or distributable
pursuant to the terms of this Agreement or otherwise, but determined without
regard to any additional payments required under this Section 7) (a "Payment")
would be subject to the excise tax imposed by Section 4999 of the Internal
Revenue Code of 1986, as amended (the "Code") or any interest or penalties are
incurred by the Executive with respect to such excise tax (such excise tax,
together with any such interest and penalties, being hereinafter collectively

after payment by the Executive of all federal, state and local taxes (including
any interest or penalties imposed with respect to such taxes), including,
without limitation, any income taxes (and any interest and penalties imposed
with respect thereto) and Excise Tax imposed upon the Gross-Up Payment, the
Executive retains an amount of the Gross-Up Payment equal to the Excise Tax
imposed upon the Payments.

                  (b) All determinations required to be made under this Section
7, including whether and when a Gross-Up Payment is required and the amount of
such Gross-Up Payment and the assumptions to be utilized in arriving at such
determination, shall be made by a nationally recognized accounting firm (the
"Accounting Firm") which shall provide detailed supporting calculations both to
the Company and the Executive within 15 business days of the receipt of notice
from the Executive that there has been a Payment, or such earlier time as is
requested by the Company. The Accounting Firm shall be appointed jointly by two
other nationally recognized accounting firms, one of which is appointed by the
Executive and one of which is appointed by the Company for such purpose. The
Accounting Firm shall not be an accounting firm serving as accountant or auditor
for the individual, entity or group effecting the Change of Control. All fees
and expenses of the Accounting Firm shall be borne by the Company. Any Gross-Up
Payment, as determined pursuant to this Section 7, shall be paid by the Company
to the Executive within five days of the receipt of the Accounting Firm's
determination. Any determination by the Accounting Firm shall be binding upon
the Company and the Executive. As a result of the uncertainty in the application
of Section 4999 of the Code at the time of the initial determination by the
Accounting Firm hereunder, it is possible that Gross-Up Payments which will not
have been made by the Company should have been made ("Underpayment"), consistent
with the calculations required to be made hereunder. In the event that the
Company exhausts its remedies

                                       8
<PAGE>   9
pursuant to this Section 7 and the Executive thereafter is required to make a
payment of any Excise Tax, the Accounting Firm shall determine the amount of the
Underpayment that has occurred and any such Underpayment shall be promptly paid
by the Company to or for the Executive's benefit.

                  (c) The Executive shall notify the Company in writing of any
claim by the Internal Revenue Service that, if successful, would require the
payment by the Company of the Gross-Up Payment. Such notification shall be given
as soon as practicable but no later then ten business days after the Executive
is informed in writing of such claim and shall apprise the Company of the nature
of such claim and the date on which such claim is requested to be paid. The
Executive shall not pay such claim prior to the expiration of the 30-day period
following the date on which it gives such notice to the Company (or such shorter
period ending on the date that any payment of taxes with respect to such claim
is due). If the Company notifies the Executive in writing prior to the
expiration of such period that it desires to contest such claim, the Executive
shall: (i) give the Company any information reasonably requested by the Company
relating to such claim; (ii) take such action in connection with contesting such
claim as the Company shall reasonably request in writing from time to time,
including, without limitation, accepting legal representation with respect to
such claim by an attorney reasonably selected by the Company; (iii) cooperate
with the Company in good faith in order to effectively contest such claim; and
(iv) permit the Company to participate in any proceeding relating to such claim;
provided, however, that the Company shall bear and pay directly all costs and
expenses (including additional interest and penalties) incurred in connection
with such contest and shall indemnify and hold the Executive harmless, on an
after-tax basis, from any Excise Tax or income tax (including interest and
penalties with respect thereto) imposed as a result of such representation and
payment of costs and expense. Without limitation on the foregoing provisions of
this Section 7, the Company shall control all proceedings taken in connection
with such contest and, at its sole option, may pursue or forego any and all
administrative appeals, proceedings, hearings and conferences with the taxing
authority in respect of such claim and may, at its sole option, either direct
the Executive to pay the tax claimed and sue for a refund or contest the claim
in any permissible manner, and the Executive agrees to prosecute such contest to
a determination before any administrative tribunal, in a court of initial
jurisdiction and in one or more appellate courts, as the Company shall
determine; provided, however, that if the Company directs the Executive to pay
such claim and sue for a refund, the Company shall advance the amount of such
payment to the Executive, on an interest-free basis, and shall indemnify and
hold the Executive harmless, on an after-tax basis, from any Excise Tax or
income tax (including interest or penalties with respect thereto) imposed with
respect to such advance or with respect to any imputed income with respect to
such advance; and further provided that any extension of the statute of
limitations relating to payment of taxes for the Executive's taxable year with
respect to which such contested amount is claimed to be due is limited solely to
such contested amount. Furthermore, the Company's control of the contest shall
be limited to issues with respect to which a Gross-Up Payment would be payable
hereunder and the Executive shall be entitled to settle or contest, as the case
may be, any other issue raised by the Internal Revenue Service or any

                                       9
<PAGE>   10
other taxing authority, so long as such action does not have a material adverse
effect on the contest being pursued by the Company.

                  (d) If, after the Executive's receipt of an amount advanced by
the Company pursuant to this Section 7, the Executive becomes entitled to
receive any refund with respect to such claim, the Executive shall (subject to
the Company's complying with the requirements of this Section 7) promptly pay to
the Company the amount of such refund (together with any interest paid or
credited thereon after taxes applicable thereto). If, after the Executive's
receipt of an amount advanced by the Company pursuant to this Section 7, a
determination is made that the Executive shall not be entitled to any refund
with respect to such claim and the Company does not notify the Executive in
writing of its intent to contest such denial of refund prior to the expiration
of 30 days after such determination, then such advance shall be forgiven and
shall not be required to be repaid and the amount of such advance shall offset,
to the extent thereof, the amount of Gross-Up Payment required to be paid.


                  8.       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 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 11), 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 11). 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

                                       10
<PAGE>   11
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 8, 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 8 shall survive the termination
of this Agreement regardless of who terminates this Agreement, or the reasons
therefor.

                  9.       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, 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

                                       11
<PAGE>   12
                  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 9 would not
                  preclude him from earning a living with an entity that is not
                  a Competitive Business.

                  (b) The terms of this Section 9 shall survive termination of
this Agreement regardless of who terminates this Agreement, or the reasons
therefor.

                  10.      Inventions

                  (a) Each invention, improvement or discovery made or conceived
by Executive, either individually or with others, during the term of his
employment with the Company, which invention, improvement or discovery is
related to any of the lines of business or work of the Companies, any projected
or potential activities which the Companies have investigated or hereinafter
investigates, or which result from or are suggested by any service performed by
Executive for the Company, whether patentable or not, shall be promptly and
fully disclosed by Executive to the Company. Executive assigns each such
invention, improvement or discovery, and the patents thereof, or related
thereto, to the Company. Executive shall, during the term of his employment with
the Company and 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 shall at all times become and remain the exclusive property of
the Company. Executive represents that he does not claim ownership of any
inventions, improvements, formulae or discoveries which are excluded from this
Agreement.

                  (b) In the event an arbitrator or a court of competent
jurisdiction determines that Executive has breached his obligations in any
material respect under

                                       12
<PAGE>   13
Sections 8, 9, or this Section 10, 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.

                  13.      Previous Agreements; Executive's Representation

                  (a) Executive and the Company hereby cancel, void and render
without force and effect all prior employment or severance agreements between
Executive and the Company ("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. Further, this release and
discharge shall not apply in any respect to the Consulting and Non-Competition
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.

                  14.      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.

                  15.      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
<PAGE>   16
                  17.      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 9 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.

                  17.      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 8, 9, and 10 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.

                  18.      Successors

                  This Agreement shall be binding upon and shall inure to the
benefit of the Company, its successors and any person, firm, corporation or
other entity which succeeds to all or substantially all of the business, assets
or property of the Company. The Company will require any successor (whether
direct or indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business, assets or property of the Company, to
expressly assume and agree to perform this Agreement in the same manner and to
the same extent that the Company would be required to perform it if no such
succession had taken place. As used in this Agreement, the "Company" shall mean
the Company as hereinbefore defined and any successor to its business, assets or
property as aforesaid which executes and delivers an agreement provided for in
this Section 18 or which otherwise becomes bound by all the terms and provisions
of this Agreement by operation of law.

                  19.      Assignment; Third Parties

                  Neither Executive nor the Company may assign, transfer,
pledge,

                                       16
<PAGE>   17
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 are intended to be third party beneficiaries of, and have rights and
interests in respect of, Executive's agreements set forth in Sections 8, 9, and
10.

                  20.      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
and the Consulting and Non-Competition Agreement embody the entire agreement and
understanding of the parties hereto in respect of the subject matter of this
Agreement, and supersede and replace all prior Agreements, understandings and
commitments with respect to such subject matter.

                  21.      Method of Payment

                  Any lump-sum payments provided for in Section 3(d) shall be

                               SPACEHAB, INC. AND

                                 INTOSPACE GmbH

                          EUROPEAN MARKETING AGREEMENT
<PAGE>   2
This Agreement is made and entered into on this __ day of _________ 1998, by and
between SPACEHAB, Inc., a corporation organized under the laws of the State of
Washington, United States of America with its principal place of business
located at 1595 Spring Hill Road, Vienna, Virginia 22182 (hereinafter referred
to as "SPACEHAB") and INTOSPACE, GmbH, a corporation organized under the laws of
the Federal Republic of Germany with its principal offices located at
Sophienstrasse 6, D-30159 Hannover, Germany (hereinafter referred to as

Since 1989 SPACEHAB and INTOSPACE have maintained a close and mutually
beneficial relationship in marketing research payload flight opportunities on

SPACEHAB, following consultations with its European partners Alenia Aerospazio
and Daimler-Benz Aerospace, and INTOSPACE, following consultations with its
Steering Board, now seek to enhance their relationship by concluding a new
marketing Agreement to replace the "Exclusive European Broker Agreement" entered
into on February 15, 1989.

This Agreement is intended to focus INTOSPACE's marketing efforts on attracting
additional European customers for research payload flight opportunities on
SPACEHAB's Shuttle-based carriers, particularly customers from the industrial
and national government sectors. In so doing, SPACEHAB and INTOSPACE hope to
promote increased microgravity research and prepare for scientific and
commercial utilization of the International Space Station.

                    ARTICLE I -- RESPECTIVE RESPONSIBILITIES

     missions provided the Joint Office planned target budget (discussed in
     Article II, below) is reached.

- -    Promote SPACEHAB research payload flight opportunities to the European
     market through:

     -    Distribution of a bimonthly newsletter "INTOSPACEHAB"

     -    Participation in European exhibitions, workshops and symposia.

     -    Periodic presentations to key European government and industry
          decision-makers.

     activities.

              ARTICLE II -- JOINT EUROPEAN CUSTOMER SUPPORT OFFICE

In support of this marketing Agreement and as noted above, INTOSPACE will
establish a Joint SPACEHAB-INTOSPACE Customer Support Office in The Netherlands
as agreed in the Share Purchase Agreement dated ______.

The activities of the Joint Customer Support Office will begin operations on
September 1, 1998 and continue through June 2001. During the third year of
operations, INTOSPACE and SPACEHAB will review the current status and
accomplishments of the Joint Customer Support Office to determine whether and
under what conditions the Joint Office should be continued.

INTOSPACE and SPACEHAB will jointly recruit a manager for the Joint Office. In
this new capacity, the Joint Office manager will carry a business card
representing the Joint Customer Support Office.

To guide the operation of the Joint Customer Support Office, INTOSPACE and
SPACEHAB will prepare an office operations plan. This plan will include a
baseline office budget as well as a target budget for the three-year period. The
baseline and target budget figures will be based on the estimates developed by
INTOSPACE and SPACEHAB in March 1998. The office operations plan will also
elaborate on INTOSPACE's planned marketing activities on SPACEHAB's behalf. The
operations plan will be completed no later than August 30, 1998 and will be
reviewed annually in June.

INTOSPACE's Managing Director and SPACEHAB's Vice President for Marketing and
Sales will be jointly responsible for the overall direction of the Joint
Customer Support Office, and for approval review and changes to the joint office
operations plan. Both representatives must approve the annual office operations
plan, and any amendments thereto.

INTOSPACE will be responsible for providing office space and other necessary
services, and for all expenses associated with the operation of the Joint
Office. SPACEHAB's sole contribution to these expenses will be made through
SPACEHAB's purchase of INTOSPACE shares as set forth in Paragraph 1.4 of the
SPACEHAB/INTOSPACE Share Purchase Agreement dated _____________.

INTOSPACE and SPACEHAB will each maintain general liability insurance to cover
the acts of their respective employees who support the activities of the Joint
Customer Support Office and other related SPACEHAB marketing activities in
Europe.

                       ARTICLE III -- MARKETING TERRITORY

For the purposes of this Agreement, the marketing activities will be performed
in Europe, which shall be defined as the geographic territory of the member
nations of the European Union as of January 1, 1998 plus Switzerland and Norway.
These European Union member states are Austria, Belgium, Denmark, Finland,
France, Germany, Greece, Ireland, Italy, Luxembourg, The Netherlands, Portugal,
Spain, Sweden, and the United Kingdom.

                         ARTICLE IV -- NON-EXCLUSIVITY

INTOSPACE will be SPACEHAB's principal European Shuttle microgravity flight
opportunity marketing agent. In this role, INTOSPACE shall promote and market
research payload flight opportunities on SPACEHAB's shuttle-based carriers on a
non-exclusive basis throughout the European territory.
<PAGE>   5
SPACEHAB reserves the right to establish additional marketing arrangements with,
and to place contracts through, other European companies in order to expand its
marketing presence in Europe. SPACEHAB will consult with INTOSPACE prior to
concluding any new European marketing arrangements. SPACEHAB will also take into
account concrete, pre-existing business arrangements that INTOSPACE may have
made and, should these arrangements result in revenues, provide appropriate
compensation to INTOSPACE for its marketing efforts.

                          ARTICLE V -- MARKETING FEES

SPACEHAB shall pay INTOSPACE marketing fees as a percentage of the final sales
price actually received from contracts executed by SPACEHAB with customers in
the European territory in accordance with the following schedule:
<PAGE>   6
<TABLE>
<CAPTION>
                    CUSTOMER                           FEE BASIS            TOTAL FEE PAID
                    --------                           ---------            --------------
<S>                                                 <C>                     <C>
     All customers in the European territory        Basic fee                    2.5%
     European Space Agency                          Basic fee                    2.5%
     European national space agencies               Basic fee + 2.5%               5%
     European industry and European Union           Basic fee + 7.5%              10%
</TABLE>

The above fee schedule replaces the fee provisions of the February 1989
"Exclusive European Broker Agreement." Notwithstanding this change, INTOSPACE
will receive a marketing fee of 10% of the executed contract amounts to be paid
to SPACEHAB for the ESA contracts for the STS-95 mission and the planned STS-107
SPACEHAB mission (or its successor if the Shuttle flight assignment is altered)
where INTOSPACE has entered into a reservation agreement with SPACEHAB and has
already begun contract negotiations with ESA.

Recent NASA/ESA Space Station barter arrangements have resulted in lost business
revenues from ESA payloads on STS-95 and STS-107. Should any future ESA and NASA
barters result in lost revenues and should NASA compensate SPACEHAB for these
lost revenues, SPACEHAB will compensate INTOSPACE in accordance with the above
fee structure.

Marketing fees paid under this Agreement are based on percentages of the total
executed SPACEHAB/European customer contract amounts actually received by
SPACEHAB exclusive of any NASA Space Shuttle or other NASA charges. These fees
will be paid within thirty (30) days of the date SPACEHAB receives full cash
payment from the customer or at such times as may be mutually agreed between
INTOSPACE and SPACEHAB. Marketing fee payments will be made using electronic
fund transfers to a bank designated in writing by INTOSPACE.

               ARTICLE VI -- INDEPENDENT CONTRACTOR RELATIONSHIP

The parties to this Agreement are and shall remain independent contractors to
one another. Notwithstanding the above-described role of the Joint Customer
Support Office manager, SPACEHAB and INTOSPACE personnel performing work in
support of this contract will continue to be employees of their existing
organizations. INTOSPACE and SPACEHAB employees are not authorized to make
commitments or create express or implied obligations on behalf of the other
party.

SPACEHAB reserves the right, in its sole discretion, to refuse to enter into a
contractual agreement with customers solicited by INTOSPACE except that SPACEHAB
shall not unreasonably or arbitrarily refuse to enter into contracts solicited
by INTOSPACE.

Except as otherwise noted in this Agreement, each party shall bear its own costs
with respect to the performance of this Agreement. No claim for the
reimbursement of such costs shall be made.

                              ARTICLE VII -- TITLE

Title to, and ownership of, all tangible personal property and software supplied
to customers or users of SPACEHAB Shuttle-based carriers or utilized in the
course of business pursuant to this Agreement shall remain with and be vested in
the party supplying such property and in no event shall the other party acquire
any right, title or interest therein.
<PAGE>   7
The property of each party provided in connection with the use of SPACEHAB
Shuttle-based carriers shall be clearly marked as to ownership, and the other
party shall not remove, change or obscure any such markings as may properly
identify the title and ownership thereof.

Title to, and ownership of, all intellectual property such as patents,
copyrights and trade secrets which are incorporated in or related to property
supplied to customers or users of SPACEHAB Shuttle-based carriers or utilized in
the course of business pursuant to this agreement shall remain with and be
vested in the party supplying such property, and in no event shall the other
party acquire any right, title, license or interest therein.

                    ARTICLE VIII -- PROPRIETARY INFORMATION

During the term of this Agreement and for a period of five (5) years from the
termination of this Agreement, each party shall not communicate, divulge or in
any manner whatsoever, directly or indirectly, make known to any other person or
entity, or use to the benefit of any third parties, any trade secrets, business
and technical knowledge, processes of manufacturing, software or software
know-how, or other proprietary information of the other party or their
customers, or the knowledge such party obtains as a result of the performance of
this Agreement, and which was disclosed and identified in writing, or if
disclosed orally then confirmed in writing within thirty (30) days, as being the
proprietary information of such disclosing party.

Neither party shall have an obligation to disclose or grant to the other party
any right to the technology that it brings to this Agreement, or may acquire by
reason of the relationship of the parties under this Agreement.

ARTICLE IX -- FULL AGREEMENT WITHOUT DELEGATION, ASSIGNMENT OR ORAL MODIFICATION

This Agreement is the complete marketing agreement between SPACEHAB and
INTOSPACE. It replaces and supersedes the February 15, 1989 Exclusive European
Broker Agreement which hereafter is null and void. This Agreement also replaces
any other representations, communications and understandings, whether written or
oral, between SPACEHAB and INTOSPACE. No oral modification of this Agreement is
permissible. A course of dealing does not effect a waiver or modification unless
ratified in writing.

duties under this Agreement without the prior written consent of the other
party.

                                 LEASE AGREEMENT

STATE OF TEXAS

COUNTY OF HARRIS

         THIS LEASE AGREEMENT, made and entered into by and between J.A. BILLIPP
DEVELOPMENT CORPORATION, A TEXAS CORPORATION hereinafter referred to as
"Landlord" and JOHNSON ENGINEERING CORPORATION hereinafter referred to as
"Tenant".

                              W I T N E S S E T H :

         1. PREMISES AND TERM. In consideration of the obligation of Tenant to
pay rent as herein provided, and in consideration of the other terms, provisions
and covenants hereof, Landlord hereby demises and leases to Tenant, and Tenant
hereby takes from Landlord certain premises to be situated at _________________
Forge River, Houston, within the County of Harris, State of Texas, 77058, more
particularly described on Exhibit "A" attached hereto and incorporated herein by
reference, together with all rights, privileges, easements, appurtenances and
amenities belonging to or in any way pertaining to the premises and together
with the building, more particularly described in the plans and specifications
of the premises which are or will be signed and initialed by the parties for
identification and attached hereto as Exhibit "B" (the "Plans") and incorporated
herein by referenced reference of building design and construction documents,
consisting of not less than 27,064 square feet of rentable area and other
improvements situated or to be situated upon said premises (the said real
property, building and improvements being hereinafter referred to as the
"Premises"). The Plans shall include the leasehold improvements to be
constructed by Landlord in the Premises. The rentable area for the entire
building is expected to be 108,300 square feet. The rentable area of the
Premises for purposes of this agreement shall be deemed to be 27,064 square
feet, however, the actual rentable area may be adjusted upward, after final
Tenant space planning is complete, as mutually agreed by Landlord and Tenant.

         TO HAVE AND TO HOLD the same for a term commencing on the "Commencement
Date", as hereinafter defined, and ending one hundred eight (108) months
thereafter, subject to the provisions of Paragraph 28 herein, provided, however,
that in the event the "Commencement Date" is a date other than the first day of
a calendar month, said term shall extend for said number of months in addition
to the remainder of the calendar month following the "Commencement Date".

         (a) The "Commencement Date" shall be the date upon which the leased
Premises shall have been substantially completed in accordance with the plans
and specifications mutually agreed to by Landlord and Tenant, hereinafter
referred to as the Commencement Date, which is anticipated to be approximately
March 15, 1994, but to be not less than eleven (11) months after Tenant gives
written notice to Landlord that
<PAGE>   2
Tenant has received the NASA Related Contract (hereinafter defined) award (the
"Award Notice"). Landlord shall notify Tenant in writing as soon as Landlord
deems said Premises to be completed and ready for occupancy as aforesaid. The
phrase "substantially completed", or derivative thereof as used herein shall be
used to describe that degree of completion as is necessary to allow Tenant to
enter upon and take possession of the Premises for the uses and purposes stated
herein, notwithstanding the fact that certain "punch list" type items may still
need to be completed. After such Commencement Date, Tenant shall, upon demand,
execute and deliver to Landlord a letter of acceptance of delivery of the
Premises provided, or as soon as, Landlord's architect certifies the Premises
have been substantially completed. In the event of any dispute as to substantial
completion of work performed or required to be performed by Landlord, the
certificate of Landlord's architect shall be conclusive.

         (b) If Landlord is unable to tender possession of the Premises to
Tenant on the Commencement Date due to any reason caused by the acts or
omissions or delays of Tenant, its agents, employees or contractors after Tenant
has given Landlord the Award Notice, then Landlord shall notify Tenant in
writing of these events and the Commencement Date shall be postponed until the
Leasehold Improvements are complete, and such postponement shall operate to
extend the expiration date specified in Section 1 in order to give full effect
to the stated duration of the term of this Lease. In this event, however, the
commencement of installments of base rental and payment of other amounts due as
provided herein shall not be postponed and shall become due and payable
commencing eleven (11) months after Tenant has given Landlord the Award Notice.

         (c) If Landlord is unable to tender possession of the Premises to
Tenant on the Commencement Date for any reason (specifically including any
delays caused in the awarding of the NASA Related Contract) other than that
specified in Paragraph 1(b) above, then the Commencement Date (and commencement
of installments of base rental and payment of other amounts due as provided
herein) shall be postponed until the Leasehold Improvements are completed, and
such postponement shall operate to extend the expiration date specified in
Section 1 in order to give full effect to the stated duration of the term of
this Lease; provided, however, that in the event Landlord is unable to tender
possession of the Premises to Tenant for any such reason not specified in
Paragraph 1(b) above before the expiration of sixty (60) days after expiration
of the eleven (11) month period after Tenant has given Landlord the Award
Notice, then Tenant, shall have the right to terminate this Lease by giving
Landlord written notice of such termination.

         (d) Landlord shall promptly notify Tenant in writing of any delay in
the Commencement Date which in the opinion of Landlord is caused for any reason
specified in Paragraph 1(b). Tenant shall promptly notify Landlord in writing of
any delay in the Commencement Date which in the opinion of Tenant is caused for
any reason specified in Paragraph 1(c). Any delay in the Commencement Date
resulting from the acts or omissions of Landlord or Tenant of which the other
party does not give such delaying party written notification shall not be
included in the ninety (90) day period referred to in Paragraph 1(c) hereof.
Landlord shall notify Tenant in advance and secure Tenant's approval to proceed
if any change requested by Tenant will result in a delay.


                                       2
<PAGE>   3
The Plans shall not be changed except pursuant to a written change order or
other written request, executed by Tenant and approved by Landlord. Any such
change may only be requested or made on behalf of Tenant by Mr. Dale R. Johnson,
or any other representative of Tenant designated to Landlord in writing.

         (e) Tenant's taking possession of the Premises shall be deemed
conclusive evidence that as of the date of taking possession thereof, the
Premises are in good order and satisfactory condition, except for latent defects
and such matters as to which Tenant gave Landlord written notice on or before
the Commencement Date; provided however, Landlord agrees that Tenant will have
thirty (30) days from the date Tenant takes occupancy of the Premises to inspect
and request any reasonable changes or repairs in defective workmanship to the
Premises, but such right shall not delay the Commencement Date or the payment of
installments of base rental or other amounts due hereunder.

         2.       RENT AND SECURITY DEPOSIT.

         (a) As part of the consideration for the execution of this Lease, and
for the lease and use of the Premises, Tenant covenants and agrees and promises
to pay as rental to Landlord or Landlord's assignees, a sum of $20,975 per month
($9.30/SF/Yr.) in months 1 - 52; and $22,555 per month ($10.00/SF/Yr.) in months
53 - 100. The first such monthly installment in the amount of $20,975 shall be
due and payable on the date of execution of this agreement, which shall be
credited toward the first monthly installment due on the Commencement Date, and
each monthly installment as stated above shall be due and payable in advance,
without demand, deduction or set off, on or before the first day of each
succeeding calendar month during the hereby demised term, except that the rental
payment for any fractional month at the commencement of the lease term shall be
prorated.

         (b) In addition, Tenant agrees to deposit with Landlord on the date
that Tenant gives written notice to Landlord to not renew or to terminate this
lease agreement, and at least four months prior to the expiration of the lease
term, the sum of twenty-two Thousand Five Hundred Fifty-Five and 00/100 Dollars
($22,555.00), which sum shall be held by Landlord, without obligation for
interest, as security for the performance of Tenant's covenants and obligations
under this Lease, it being expressly understood and agreed that such deposit is
not an advance rental deposit or a measure of Landlord's damages in case of
Tenant's default. Upon the occurrence of any event of default by Tenant,
Landlord may without prejudice to any other remedy provided herein or provided
by law, use such funds to the extent necessary to make good any arrears of rent
or other payments due Landlord hereunder, and any other damage, injury, expense
or liability caused by such event of default. Although the security deposit
shall be deemed the property of the Landlord, all or any remaining balance of
such deposit shall be returned by Landlord to Tenant at such time after
termination of this Lease that all Tenant's obligations under this Lease have
been fulfilled.

         (c) Tenant agrees to pay to Landlord, as additional rental, all charges
for any service, goods, or materials furnished by Landlord at Tenant's request
which are


                                       3
<PAGE>   4
not required to be furnished by Landlord under this Lease, (as well as all other
sums payable by Tenant hereunder), within thirty (30) days after Landlord
renders a statement therefor to Tenant. All past due installments of rent and
additional rental amounts shall bear interest from the date due until paid at
the rate of Texas Commerce Bank Prime Rate plus three percent (3%) per annum.
Additionally, if Landlord incurs any expenses or costs as a result of Tenant's
failure to pay any installment of rent or additional rental amount when due,
then Tenant shall immediately upon receipt of notice of such expense or cost
from Landlord reimburse Landlord for such amount.

         3. USE. The Premises shall be used only for the purpose of business
offices, receiving, storing, shipping, light manufacturing and selling (other
than retail) products, materials, merchandise and services made and/or
distributed by Tenant, photography laboratory, and for any other lawful and
permitted purposes. Tenant shall conduct such activities in such a manner as to
not constitute a violation of the covenants and deed restrictions of Bay Terrace
Subdivision and Friendswood Development Company. Outside storage, including,
without limitation, trucks and other vehicles, is prohibited without Landlord's
prior written consent. Tenant shall at its own cost and expense obtain any and
all licenses and permits necessary for any use of the Premises. Tenant shall
comply with all governmental laws, ordinances and regulations applicable to the
use of the Premises, and shall promptly comply with all governmental orders and
directives for the correction, prevention and abatement of nuisances in or upon,
or connected with the Premises, all at Tenant's sole expense. Tenant shall not
permit any objectionable or unpleasant odors, smoke, dust, gas, noise or
vibrations to emanate from the Premises. Without Landlord's prior written
consent, Tenant shall not receive, store or otherwise handle any product,
material or merchandise which is explosive or highly inflammable. Tenant will
not permit the Premises to be used for any purpose which would render the
property or liability insurance thereon void or the insurance risk more
hazardous or cause the State Board of Insurance or other insurance authority to
disallow any sprinkler credits.

         4.       TAXES AND OTHER ASSESSMENTS.

         (a) Tenant agrees to pay to Landlord or directly to the various taxing
authorities, before they become delinquent, Tenant's prorata share of all taxes
(both general and special), assessments or governmental charges of any kind and
nature whatsoever (hereinafter collectively referred to as the "taxes"), levied
or assessed against the Premises or any part thereof before they become
delinquent. Taxes are deemed to be additional rentals payable by Tenant and are
subject to the provisions of Paragraph 2(b) above.

         (b) If at any time during the term of this Lease, the present method of
taxation shall be changed so that in lieu of the whole or any part of any taxes,
assessments, levies or charges levied, assessed or imposed on the Premises
thereon there shall be levied, assessed or imposed on Landlord a capital levy or
other tax directly on the rents received therefrom and/or a franchise tax,
assessment, levy or charge measured by or based, in whole or in part upon such
rents for the Premises, then all such taxes,


                                       4
<PAGE>   5
assessments, levies or charges or the part thereof so measured or based, shall
be deemed to be included within the term "taxes" for the purposes hereof.

         (c) Any payment to be made pursuant to this Paragraph 4 with respect to
the real estate tax year in which this Lease commences or terminates shall bear
the same ratio to the payment which would be required to be made for the full
tax year as that part of such tax year covered by the term of this Lease bears
to a full tax year.

         (d) The Landlord shall have the right to employ a tax consulting firm
to attempt to assure a fair tax burden on the Premises within the applicable
taxing jurisdictions. Tenant shall reimburse Landlord for the cost of such
service, which shall not exceed $400/Yr., unless otherwise agreed by and between
Landlord and Tenant.

         (e) Tenant may, at its sole cost and expense, in its own name and/or in
the name of Landlord, dispute and contest any Taxes, appraisals, or valuations.
Landlord, as owner of the demised Premises, agrees to lend friendly assistance
to Tenant in connection with all matters pertaining to Taxes hereunder,
including, without limitation, joining in any proceedings instituted by Tenant
in respect thereof, provided Tenant indemnifies and holds Landlord harmless from
any costs incurred by Landlord in respect thereof.

         (f) Tenant agrees to pay to Landlord all owners' association (Clear
Lake City Community Association) annual assessments (currently covers
maintenance and repair of public recreational facilities, street medians and
subdivision entrance ways and ambulance service) and any special assessments
levied or assessed against the Premises or any part thereof before they become
delinquent. Tenant may elect to make such payments payable directly to the
appropriate assessment authorities and Landlord shall give written notice to
Tenant within five (5) days after receipt of assessment payments from Tenant
that such payments have been forwarded to the appropriate assessment
authorities. Any sums paid by Landlord on behalf of Tenant shall be deemed to be
additional rental owed by Tenant to Landlord and shall be due and payable on
demand by Landlord together with interest thereon at the rate of Texas Commerce
Bank Prime Rate plus three percent (3%) per annum if not received from Tenant
within thirty (30) days from the date the invoice is received from Landlord.

         5.       REPAIRS AND MAINTENANCE.

         (a) After completion by Landlord of the building and the leasehold
improvements specified in Exhibit "B", Tenant shall at its own cost and expense
keep, maintain and take good care of the Premises and, except as expressly
provided in Paragraph 11(b) hereof, make all necessary repairs thereto, interior
and exterior, ordinary and extraordinary, and shall suffer no waste or nuisance,
however, Tenant shall not be responsible for latent construction or material
defects. Landlord will be responsible only for repairs required to maintain the
structural integrity of the building foundation, concrete wall panels and steel
structure, unless such repairs are required as a result of Tenant damage. Any
material and/or equipment warranties or guarantees provided by the construction
contractor will be administered by Landlord for the benefit of Tenant. At


                                       5
<PAGE>   6
the end of the term or other termination of this Lease, Tenant shall deliver the
Premises with all improvements thereon in good repair and condition, reasonable
wear and tear only excepted. Tenant may request Landlord to complete any or all
of these Tenant maintenance or repair responsibilities and will reimburse
Landlord for Landlord's direct cost of such maintenance or repair.

         (b) Tenant at its own cost and expense shall be responsible for its
prorata share of the maintenance and care of the building and grounds around the
building on the Premises, including the regular mowing of grass, care of shrubs
and general landscaping and will keep the parking areas, driveways, alleys and
the whole of the Premises in a clean and sanitary condition. Landlord will
administer these services, and Tenant shall reimburse Landlord for Tenant's
prorata share of Landlord's direct cost and expense.

         (c) Tenant at its own cost and expense shall enter into a regularly
scheduled preventive maintenance/service contract with a maintenance contractor
for servicing all hot water, heating and air conditioning systems and equipment
within the Premises. The service contract will include all services suggested by
the equipment manufacturer within the operation/maintenance manual and will
become effective (and a copy thereof delivered to Landlord) within thirty (30)
days of the date Tenant takes possession of the Premises.

         (d) The Landlord shall provide a ten (10) year manufacturer's guaranty
for the building roof system from Owens-Corning Fiberglass Corporation (or
equal). The guaranty will be administered by Landlord for the benefit of
Tenant(s).

         6. ALTERATIONS. Tenant shall not make any alterations, additions or
improvements to the Premises without the prior written consent of Landlord.
Tenant may, without the consent of Landlord, but at its own cost and expense and
in a good workmanlike manner make such minor alterations, additions or
improvements or erect, remove or alter such partitions, or erect such shelves,
bins, machinery and trade fixtures as it may deem advisable, without altering
the basic character of the building or improvements and without overloading or
damaging such building or improvements, and in each case complying with all
applicable governmental laws, ordinances, regulations, and other requirements.
All alterations, additions, improvements and partitions erected by Tenant shall
be and remain the property of Tenant during the term of the Lease. Unless
otherwise mutually-agreed by Landlord and Tenant, such improvements shall become
the property of the Landlord as of the date of the end of the term of this Lease
(as such term may be extended pursuant to any renewals, extensions or holdover
period) and shall be delivered up to the Landlord with the Premises and Tenant
shall have no obligation to restore the premises to their original condition.
All shelves, bins, machinery and trade fixtures installed by Tenant will be
removed by Tenant prior to the termination of this Lease, unless otherwise
agreed by Landlord. All such removals and restoration shall be accomplished in
good workmanlike manner so as not to damage the primary structure or structural
qualities of the building and other improvements situated on the Premises.


                                       6
<PAGE>   7
         7. SIGNS. Tenant shall have the right to install signs upon the
exterior of the building only when first approved in writing by Landlord and
subject to any applicable governmental laws, ordinances, regulations, deed
restrictions and other requirements. Tenant shall remove all such signs upon the
termination of this Lease. Such installations and removals shall be made in such
manner as to avoid injury to or defacement of the building and other
improvements. Tenant shall repair any injury or defacement, including without
limitation discoloration, caused by such installation and/or removal, if so
required by Landlord. Landlord will provide an allowance of up to $3,000 for the
installation of a building or monument sign as specified by Tenant.

         8. INSPECTION. Subject to Tenant's reasonable security regulations,
Landlord and Landlord's agent and representatives shall have the right to enter
and inspect the Premises at any reasonable time during business hours, for the
purpose of ascertaining the condition of the Premises after receiving prior
permission from Tenant. During the period that is six (6) months prior to the
end of the term hereof, Landlord and Landlord's agents and representatives shall
have the right, with the prior consent of Tenant, to enter the Premises at any
reasonable time during business hours for the purpose of showing the Premises
and shall have the right to erect on the Premises a suitable sign indicating
that the Premises are available for lease. Tenant shall give written notice to
Landlord at least thirty (30) days prior to vacating the Premises and shall
arrange to meet with Landlord for a joint inspection of the Premises prior to
vacating.

         9. UTILITIES. Landlord agrees to provide water, electricity, and
telephone service connections to the Premises; but Tenant shall pay all charges
incurred for any utility services used on or from the Premises, and any
maintenance charges for utilities, and shall furnish all replacement electric
light bulbs and tubes. Landlord shall in no event be liable for any interruption
or failure of utility services on the Premises.

         10.      ASSIGNMENT AND SUBLETTING.

         (a) Neither Tenant nor Tenant's legal representatives or successors in
interest by operation of law or otherwise shall assign this Lease or sublease
the leased Premises or any part thereof, or mortgage, pledge or hypothecate its
leasehold interest or grant any concession or license within the leased Premises
without the prior written permission of Landlord (which permission shall not be
unreasonably withheld or delayed), and any attempt to do any of the foregoing
without the prior express written permission of Landlord shall be void and of no
effect. Notwithstanding the foregoing, Landlord's consent shall not be required
for the assignment or subletting, in whole or in part, of the Leased Premises to
any parent, subsidiary, division or affiliate of Tenant, or any corporation in
or with which any of the foregoing may be duly merged, converted or consolidated
under any statutory proceeding, or to NASA (National Aeronautics & Space
Administration); provided, however, Tenant shall give Landlord written notice
prior to any such assignment or subletting, and any such assignment or
subletting by Tenant shall not serve to release Tenant from primary liability
hereunder.

         (b) Notwithstanding that the prior written permission of Landlord to
any of the aforesaid transactions may have been obtained, the following shall
apply:


                                       7
<PAGE>   8
                  (1) In the event of an assignment, contemporaneously with the
         granting of Landlord's aforesaid consent, Tenant shall cause the
         assignee to expressly assume in writing and agree to perform all of the
         covenants, duties and obligations of Tenant hereunder.

                  (2) A signed counterpart of all instruments relative thereto
         (executed by all parties to such transaction with the exception of
         Landlord) shall be submitted by Tenant to Landlord prior to or
         contemporaneously with the request for Landlord's written consent
         thereto (it being understood that no such instrument shall be effective
         without the written consent of Landlord).

                  (3) No usage of the leased Premises different from the usage
         herein provided to be made by Tenant shall be permitted, and all other
         terms and provision of this Lease shall continue to apply after any
         such assignment or subleasing.

         11.      INSURANCE; FIRE AND CASUALTY DAMAGE.

         (a) Landlord agrees to maintain property insurance covering the
Premises in an amount not less than 90% (or such greater percentage as may be
necessary to comply with the provisions of any co-insurance clauses of the
policy) of the "replacement cost" thereof as such term is defined in the
Replacement Cost Endorsement to be attached thereto, insuring against the perils
of Fire, Lightning, Extended Coverage, Vandalism and Malicious Mischief,
extended by Special Extended Coverage Endorsement to insure against all other
Risks of Direct Physical Loss, such coverage and endorsements to be as defined,
provided and limited in the standard bureau forms prescribed by the insurance
regulatory authority for the State of Texas for use by insurance companies
admitted in Texas for the writing of such insurance on risks located within
Texas. Such insurance shall cover those risks of loss that a reasonable and
prudent property owner of a like or similar building located in Clear Lake City
or Houston, Texas would insure against, including liability and loss of rents
coverage. Subject to the provisions of subparagraphs 11(b), 11(c) and 11(g)
below, such insurance shall be for the sole benefit of Landlord. Tenant shall
reimburse Landlord Tenant's prorata share for Landlord's direct cost of
maintaining such property insurance.

         (b) Tenant shall provide, at Tenant's own expense, all insurance
coverage necessary or desirable to cover Tenant's goods, furniture or other
property placed in the leased Premises, and Tenant shall further maintain
comprehensive general liability insurance to include coverage for its business
operations, independent contractors, contractual and products coverage for its
business operations, independent contractors, contractual and products coverage,
with limits for bodily injury liability of not less than $1,000,000 and limits
for property damage of not less than the greater of $100,000 or the full
insurable value of Tenant's property. Landlord shall not be obligated to insure
any portion of the leased Premises consisting of tenant improvements other than
the Leasehold Improvements, or any of Tenant's goods, fixtures, furniture or
other property placed or incorporated in the leased Premises.


                                       8
<PAGE>   9
         (c) If the Premises should be damaged or destroyed by any peril covered
by the insurance to be provided by Landlord under subparagraph 11(a) above,
Tenant shall give immediate notice thereof to Landlord and Landlord shall at its
sole cost and expense, but only to the extent insurance proceeds are available,
thereupon proceed with reasonable diligence to rebuild and repair the Premises
to substantially the condition in which they existed prior to such damage or
destruction, except that Landlord shall not be required to rebuild, repair or
replace any part of the partitions, fixtures, additions and other improvements
which may have been placed in, on or about the Premises by Tenant.

         (d) If at any time during the Lease term, the leased Premises or any
portion of the building shall be damaged or destroyed by fire or other casualty
in such a manner as to require substantial alteration or reconstruction of the
building or the leased Premises, and such alterations or reconstruction cannot
be completed within 180 days from the date of the damage, then Landlord or
Tenant shall have the election to terminate this Lease.

         (e) In the event Tenant elects not to terminate the Lease, rental shall
abate proportionately during the period and to the extent that the leased
Premises are unfit for use by Tenant in the ordinary conduct of its business. If
Landlord and Tenant mutually agree that Landlord is able to repair and restore
the leased Premises or the building within the time provided in Subparagraph
11d) above, this Lease shall continue in full force and effect and such repairs
will be made within a reasonable time thereafter, subject to delays arising from
shortages of labor or material, acts of God, war or other conditions beyond
Landlord's reasonable control. In the event that this Lease is terminated as
herein provided, Landlord shall refund to Tenant any prepaid rent (as of the
date of damage or destruction) less any sum then owing Landlord by Tenant.

         (f) If the Premises should be damaged or destroyed by a casualty other
than a peril covered by the insurance to be provided under subparagraph 11(a)
above, and the casualty or loss was the result of willful misconduct or gross
negligence by Tenant or Tenant's employees, agents, guests, customers,
representatives or invitees, Tenant shall at its sole cost and expense thereupon
proceed with reasonable diligence to rebuild and repair the Premises to
substantially the condition in which they existed prior to such damage or
destruction, in accordance with the original plans and specifications for the
building and Premises.

         (g) Notwithstanding anything herein to the contrary, in the event the
holder of any indebtedness secured by a mortgage or deed of trust covering the
Premises requires that the insurance proceeds be applied to such indebtedness as
a result of total loss or constructive total loss of the Premises, then the
Landlord shall have the right to terminate this Lease by delivering written
notice of termination to Tenant within fifteen (15) days after such requirement
is made by any such holder, whereupon all rights and obligations hereunder shall
cease and terminate. The insurance proceeds arising out of any loss which is not
a total loss or a constructive total loss shall be applied by Landlord in the
manner prescribed in subparagraph 11(c) above.

         (h) Each of Landlord and Tenant hereby releases the other from any and
all liability or responsibility to the other or anyone claiming through or under
them by way of subrogation or otherwise for any loss or damage to property
caused by fire or any other perils insured in policies of insurance covering
such property, even if such loss or damage shall have been caused by the fault
or negligence of the other party, or anyone for whom such party may be
responsible, provided, however, that this release shall be applicable and in
force and effect only with respect to loss or damage occurring during such times
as the releasor's policies shall contain a clause or endorsement to the effect
that any such release shall not adversely affect or impair said policies or
prejudice the right of the releasor to recover thereunder and then only to the
extent of the insurance proceeds payable under such policies. Each of Landlord
and Tenant agrees that it will request its insurance carriers to include in its
policies such a clause or endorsement. If extra cost shall be charged therefor,
each party shall advise the other thereof and of the amount of the extra cost,
and the other party, at its election, may pay the same, but shall not be
obligated to do so.

         12. LIABILITY. Landlord shall not be liable to Tenant or Tenant's
employees, agents, patrons or visitors, or to any other person whomsoever, for
any injury to person or damage to property on or about the Premises, caused by
the negligence or misconduct of Tenant, its agents, servants or employees, or of
any other person entering upon the Premises under express or implied invitation
of Tenant, or caused by the buildings and improvements located on the Premises
becoming out of repair, or caused by leakage of gas, oil, water or steam or by
electricity emanating from the Premises, or due to any cause whatsoever. Tenant
shall procure and maintain throughout the term of this Lease a policy or
policies of insurance, at its sole cost and expense, insuring both Landlord and
Tenant against all claims, demands, or actions arising out of or in connection
with: (i) the Premises; (ii) the condition of the Premises; and (iii) Tenant's
operations in and maintenance and use of the Premises. The limits of such policy
or policies should have a combined single limit of not less than $1,000,000 per
person and per occurrence in respect of injury to persons (including death) and
not less than $100,000 per occurrence in respect of property damage or
destruction, including loss of use thereof. All such policies shall be procured
by Tenant from responsible insurance companies satisfactory to Landlord.
Certificates of Insurance for each such policies, shall be delivered to
Landlord, upon Landlord's written request. Not less than fifteen (15) days prior
to the expiration date of any such policies, new Certificates of Insurance shall
be delivered to Landlord upon Landlord's written request. Such policies shall
further provide that not less than thirty (30) days written notice shall be
given to Landlord before such policy may be cancelled or changed to reduce
insurance provided thereby.

         13. CONDEMNATION/EMINENT DOMAIN. If there shall be taken by
condemnation or by exercise of the power of eminent domain during the term of
this Lease any substantial part of the leased Premises, the building or the
land, either Tenant or Landlord may elect to terminate this Lease or continue
same in effect. If both Landlord and Tenant may mutually elect to continue this
Lease in effect, the base rental shall be reduced in proportion to the area of
the leased Premises taken, if any, and Landlord shall repair any damage to the
leased Premises or the building which results from such taking. All sums awarded
or agreed upon between Landlord and the


                                       10
<PAGE>   11
condemning authority for the taking of the interest of Landlord or Tenant,
whether as damages or as compensation, will be the property of Landlord, without
prejudice, except for claims of Tenant against the condemning authority on
account of the unamortized cost of improvements which have been paid for by
Tenant or relocation assistance, as applicable. If this Lease should be
terminated under any provisions of this Paragraph 13, base rental and other sums
payable hereunder, shall be payable up to the date that possession is taken by
the taking authority, and Landlord will refund to Tenant any prepaid unaccrued
rent, less any sum then owing by Tenant to Landlord. Should such partial taking
render the remaining portion of the Leased Premises unusable for the conduct of
Tenant's business, then Tenant shall have the right to terminate this Lease.

         14. HOLDING OVER. Tenant will, at the termination of this Lease by
lapse of time or otherwise, yield up immediate possession to Landlord. If
Landlord agrees in writing that Tenant may hold over after the expiration or
termination of this Lease, unless the parties hereto otherwise agree in writing
on the terms of such holding over, the hold over tenancy shall be subject to
termination by Landlord at any time upon not less than five (5) days advance
written notice, or by Tenant at any time upon not less than thirty (30) days
advance written notice, and all of the other terms and provisions of this Lease
shall be applicable during that period, except that Tenant shall pay Landlord
from time to time upon demand, as rental for the period of any hold over, an
amount equal to one and one-half (1-1/2) times rent in effect on the expiration
or termination date, computed on a daily basis for each day of the hold over
period. No holding over by Tenant, whether with or without consent of Landlord,
shall operate to extend this Lease except as otherwise expressly provided. The
preceding provisions of this Paragraph 14 shall not be construed as Landlord's
consent for Tenant to hold over.

         15. QUIET ENJOYMENT. Landlord covenants that it now has, or will
acquire before Tenant takes possession of the Premises, good title to the
Premises, free and clear, of all liens and encumbrances, excepting only the lien
for current taxes not yet due, such mortgage or mortgages as are permitted by
the terms of this Lease, zoning ordinances and other building and fire
ordinances and governmental regulations relating to the use of such property,
and easements, restrictions and other conditions of record. Landlord represents
and warrants that it has full right and authority to enter into this Lease and
that Tenant upon paying the rental herein set forth and performing its other
covenants and agreements herein set forth, shall peaceably and quietly enjoy the
Premises for the term hereof without hindrance or molestation from any person,
subject to the terms and provisions of this Lease.

         16. EVENTS OF DEFAULT. The following events shall be deemed to be
events of default by Tenant under this Lease:

         (a) Tenant shall fail to pay any installment of the rent hereby
reserved when due, or any other payment or reimbursement to Landlord required
herein, and such failure shall continue for a period of ten (10) days from the
date of written notification from Landlord to Tenant delivered to address
herein.


                                       11
<PAGE>   12
         (b) Tenant shall become insolvent, or shall make a transfer in fraud of
creditors, or shall make an assignment for the benefit of creditors.

         (c) Tenant shall file a petition, voluntary or involuntary, under any
section or chapter of the National Bankruptcy Act, as amended, or under any
similar law or statute of the United States or any State thereof, or Tenant
shall be adjudged bankrupt, or insolvent in proceedings filed against Tenant
thereunder.

         (d) A receiver or trustee shall be appointed for all or substantially
all of the assets of Tenant.

         (e) Tenant shall fail to comply with any term, provision or covenant of
this Lease (other than the foregoing in this Paragraph 16), and shall not
undertake good faith efforts to cure such failure within twenty (20) days after
written notice thereof to Tenant.

         17. REMEDIES. Upon the occurrence of any of such events of default
described in Paragraph 16 hereof, Landlord shall have the option to pursue any
one or more of the following remedies without any notice or demand whatsoever:

         (a) Terminate this Lease, after first giving thirty (30) days written
notice to Tenant at its Houston address, in which event Tenant shall immediately
surrender the Premises to Landlord, and if Tenant fails so to do, Landlord may,
without prejudice to any other remedy which it may have for possession or
arrearage in rent, enter upon and take possession of the Premises and Tenant
agrees to pay to Landlord on demand the amount of any loss and damage which
Landlord may suffer by reason of such termination, whether through inability to
relet the Premises on satisfactory terms or otherwise.

         (b) Enter upon and take possession of the Premises; and relet the
Premises and receive the rent therefor; and Tenant agrees to pay to the Landlord
on demand any deficiency that may arise by reason of such reletting. In the
event Landlord is successful in reletting the Premises at a rental in excess of
that agreed to be paid by Tenant pursuant to the terms of this Lease, Landlord
and Tenant each mutually agree that Tenant shall not be entitled, under any
circumstances, to such excess rental, and Tenant does hereby specifically waive
any claim to such excess rental.

         (c) Enter upon the Premises, and do whatever Tenant is obligated to do
under the terms of this Lease; and Tenant agrees to reimburse Landlord on demand
for any expenses which Landlord may incur in thus effecting compliance with
Tenant's obligations under this Lease.

         (d) Alter locks and other security devices at the Premises.

         (e) Receive payment from Tenant, in addition to any sum provided to be
paid above, for any and all of the following expenses for which Tenant shall be
considered liable:


                                       12
<PAGE>   13
                  1. Broker's fees incurred by Landlord in connection with
         reletting the whole or any part of the Premises;

                  2. The cost of repairing, altering, remodeling or otherwise
         putting the Premises into condition, acceptable to a new tenant or
         tenants, plus a reasonable charge to cover overhead;

                  3. The cost of removing and storing Tenant's or other
         occupants' property; and

                  4. All reasonable expenses incurred by Landlord in enforcing
         Landlord's remedies.

         In the event Tenant fails to pay and installment of rent hereunder as
and when such installment is due, to help defray the additional cost to
Landlord for processing such late payments Tenant shall pay to Landlord on
demand a late charge in an amount equal to five percent (5%) of such
installment; and the failure to pay such amount within thirty (30) days after
receipt of written demand notice from Landlord to Tenant shall be an event of
default hereunder. The provision for such late charge shall be in addition to
all of Landlord's other rights and remedies hereunder or at law and shall not be
construed as liquidated damages or as limiting Landlord's remedies in any
manner.

         Pursuit of any of the foregoing remedies shall not preclude pursuit of
any of the other remedies herein provided or any other remedies provided by law,
nor shall pursuit of any remedy herein provided constitute a forfeiture or
waiver of any rent due to Landlord hereunder or of any damages accruing to
Landlord by reason of the violation of any of the terms, provisions and
covenants herein contained. No act or thing done by the Landlord or its agents
during the term hereby granted shall be deemed a termination of this Lease or an
acceptance of the surrender of the Premises, and no agreement to terminate this
Lease or to accept a surrender of said Premises shall be valid unless in writing
and signed by Landlord. No waiver by Landlord of any violation or breach of any
of the terms, provisions and covenants herein contained shall be deemed or
construed to constitute a waiver of any other violation or breach of any of the
other terms, provisions and covenants herein contained. Landlord's acceptance of
the payment of rental or other payments hereunder after the occurrence of an
event of default shall not be construed as a waiver of such default, unless
Landlord so notifies Tenant in writing. Forbearance by Landlord to enforce one
or more of the remedies herein provided upon an event of default shall not be
deemed or construed to constitute a waiver of such default or of any subsequent
default. If, on account of any breach or default by Tenant in Tenant's
obligations under the terms and conditions of this Lease, it shall become
necessary or appropriate for Landlord to employ or consult with an attorney
concerning any of Landlord's rights or remedies hereunder or to enforce or
defend any of the Landlord's rights or remedies hereunder, Tenant agrees to pay
any reasonable attorney's fees so incurred.

<PAGE>   14
         18.      SUBORDINATION AND LANDLORD'S MORTGAGEE.

         (a) This Lease Agreement shall be automatically subject to and
subordinated, at Landlord's option, to any lease wherein Landlord is the tenant
and to any lien of any mortgage or deed of trust, provided Landlord delivers to
Tenant a non-disturbance agreement executed by Landlord's mortgagee(s) in a form
reasonably acceptable to Tenant, Landlord, and Landlord's mortgagee(s). Although
no instrument or act on the part of the Tenant shall be necessary to effectuate
such subordination, the Tenant will, nevertheless, execute and deliver such
further instruments, including reasonable non-material amendments to this Lease,
subordinating this Lease to the lien of any such lease or mortgage, as may be
required by the lessor or mortgagee(s), provided that any such instrument Tenant
is requested to execute, shall contain a reasonable non-disturbance and
attornment agreement by the lessor or mortgagee requesting subordination.

         (b) Tenant will, at such time or times as Landlord or Landlord's
mortgagee may request, sign a certificate stating whether this Lease is in full
force and effect; whether any amendments or modifications exist; whether there
are any defaults hereunder; and such other information and agreements, as may be
reasonably requested.

         19.      LANDLORD'S DEFAULT.

         (a) In the event Landlord should default in any of its obligations
hereunder, Tenant shall simultaneously give Landlord and Landlord's mortgagee
written notice specifying such default and Landlord shall thereupon have thirty
(30) days (plus an additional reasonable period as may be required in the
exercise by Landlord of due diligence) in which to cure any such default. In
addition, Landlord's mortgagee shall have the right (but not the obligation) to
cure or remedy such default during the period that is permitted to Landlord
hereunder, plus an additional period of thirty (30) days, and Tenant will accept
such curative or remedial action taken by Landlord's mortgagee with the same
effect as if such action had been taken by Landlord.

         (b) Upon the failure of Landlord or Landlord's mortgagee to cure such
default in accordance with the provisions of Paragraph 19(a) hereof, Tenant
shall be authorized and empowered to pay any such items for and on behalf of
Landlord, and the amount of any item so paid by Tenant for and on behalf of
Landlord, together with any interest or penalty required to be paid in
connection therewith, shall be payable on demand by Landlord to Tenant.

         20. ASSIGNMENT BY LANDLORD. Landlord shall have the right to assign or
transfer, in whole or in part every feature of its rights and obligations
hereunder and the Premises provided such assignee or transferee recognizes and
agrees to be bound by the terms of this Lease. Such assignments or transfers may
be made to a corporation, trust, trust company, individual or group of
individuals, and howsoever made shall be in all things respected and recognized
by Tenant.


                                       14
<PAGE>   15
         21. DISCLAIMER. This Lease and the obligation of Tenant to pay rent
hereunder and perform all of the other covenants and agreements hereunder on the
part of the Tenant to be performed shall not be affected, impaired or executed
because Landlord is unable to fulfill any of its covenants and obligations under
this Lease, expressly or impliedly to be performed by Landlord, if Landlord is
prevented or delayed from doing so by reason of strikes, labor troubles,
accident, or by any reason or cause whatsoever reasonably beyond Landlord's
control. Reasons beyond Landlord's control shall include, but not be limited to,
laws, governmental preemption in connection with a National Emergency or by any
reason of any rule, order or regulation of any governmental agency, federal
state, county or municipal authority or any department or subdivision thereof,
or by reason of the conditions of supply and demand which have been or are
affected by war or other emergency. In the event Landlord is unable to fulfill
any of its covenants and obligations under this Lease for reasons beyond its
control, such that Tenant's ability to use the Premises for its intended purpose
is partially or wholly impaired, and this condition continues for a period of
sixty (60) consecutive days, after receipt of written notice to Landlord from
Tenant, then Tenant's obligation to pay rent hereunder shall partially or wholly
abate until such condition is cured, at which time Tenant's obligation to pay
rent hereunder shall resume.

         22. MECHANIC'S LIENS. Tenant shall have no authority, express or
implied, to create or place any lien or encumbrance, of any kind or nature
whatsoever, upon, or in any manner to bind, the interest of Landlord in the
Premises for any claim in favor of any person dealing with Tenant, including
those who may furnish materials or perform labor for any construction or
repairs, and each such claim shall affect and each such lien shall attach to, if
at all, only the leasehold interest granted to Tenant by this instrument. Tenant
covenants and agrees that it will pay or cause to be paid all sums legally due
and payable by it on account of any labor performed or materials furnished in
connection with any work performed on the Premises on which any lien is or can
be validly and legally asserted against its leasehold interest in the Premises
or the improvements thereon, and that it will save and hold Landlord harmless
from any and all loss, cost or expense based on or arising out of asserted
claims or liens against the leasehold estate or against the right, title and
interest of the Landlord in the Premises or under the terms of this Lease.

         23. NOTICES. Each provision of this instrument or of any applicable
governmental laws, ordinances, regulations and other requirements with reference
to the sending, mailing or delivery of any notice or the making of any payment

shall have the right to renew and extend this Lease with respect to all of the
leased Premises, for one (1) renewal term of up to sixty (60) months (such term
being hereinafter referred to as the "Renewal Term"), commencing upon the
expiration of the initial one hundred eight (108) month term of this Lease. The

<PAGE>   20
         (b) In order to exercise such renewal option, Tenant shall advise
Landlord in writing of its intention to renew not less than six (6) months prior
to the expiration of the initial term of the Lease.

         (c) During the Renewal Term of this Lease, the renewal Premises shall
be leased by Tenant on an "as is" basis, unless otherwise agreed upon in
writing, and Landlord shall not be obligated to make any alterations or install
or modify any improvements therein. The leasing of the Premises during any
Renewal Term hereof shall be upon the same terms and conditions as are set forth
in this Lease.

         28. EARLY TERMINATION PROVISION. Only in the event that Tenant no
longer has the NASA "Flight Crew Systems Development Contract" (FCSDC) or its
equivalent being more fully described in Exhibit "C" attached hereto ("NASA
Related Contract"), Tenant shall have the right after five (5) years from the
date of commencement of the NASA Related Contract, but not less than fifty-two
(52) months from the Lease Commencement Date, to wholly (but not partially)
terminate this Lease with no further rental payments or obligations, after first
giving four (4) months prior written notice to Landlord ("First Right to
Terminate"). Similarly, if Tenant no longer has the NASA Related Contract or its
equivalent, Tenant shall also have the right after eight (8) years from the date
of commencement of the NASA Related Contract, to wholly (but not partially)
terminate this Lease with no further rental payments or obligations, after first
giving four (4) months prior written notice to Landlord ("Second Right to
Terminate").

         29. EXPANSION OPTIONS. After receiving written notice from Landlord of
its intent to lease to a third-party tenant, Tenant shall have the first right,
prior to building completion, to lease up to 4,050 square feet (one 135' X 30'
bay) immediately adjacent to the Premises, with the expansion lease term to
coincide with the primary Lease term. Landlord shall provide a Tenant
improvement allowance of $16.00 per square foot for this expansion space, with
the annual base rental rate for the expansion space to be the same as the annual
base rental rate for the primary Premises.

         30. PARKING. In accordance with Clear Lake City Development Guidelines
and Friendswood Development Company requirements, Landlord shall provide a
minimum of 4.5 automobile parking spaces per 1,000 square feet of Tenant lease
area.

         31. OPERATING EXPENSES AND BUILDING MANAGEMENT. Notwithstanding Tenant
obligations as stated herein, Landlord shall agree to perform all building and
property maintenance and management functions on behalf of Tenant, and Tenant
shall reimburse Landlord for Landlord's cost of providing these services. In
this regard, Landlord shall guarantee Tenant that for the initial Lease year the
cost of building/grounds maintenance and services, janitorial and trash removal,
and property management shall not exceed $1.50 per square foot in the aggregate.
Tenant acknowledges that it will continue to be responsible for its prorata
share of property taxes, owners association fees, extended coverage building
insurance, electrical service and water service, which shall be invoiced by the
Landlord and paid directly by the Tenant.


                                       20
<PAGE>   21
         Landlord will allow Tenant to audit Landlord's books and records
relating to the operating expenses and building management during normal
business hours after a written request to Landlord describing which expenses
Tenant wishes to examine. Landlord will use its best efforts to obtain services,
including building maintenance, management, and property insurance that are
competitively priced and of the quality befitting a Class "A" office/technical
building in the Clear Lake area.

         32. NASA CONTRACT AWARD. All terms of this Lease Agreement shall be
subject to Landlord receiving written notice from Tenant confirming that Tenant
has been awarded the NASA Related Contract for a contract term (including NASA
options) of at least nine (9) years, and confirming the final square footage of
the Premises and the commencement date of the NASA Related Contract. Unless
otherwise agreed by Landlord and Tenant, if Tenant has not provided such written
notice prior to April 30, 1993, Landlord and Tenant may agree in good faith to
adjust the Commencement Date and/or the Base Rental Rates and/or the building
size stated herein, if required to satisfy possible changes in development
schedule and/or interest rates and/or project financing requirements. If both
parties are unable to reach a mutually-acceptable Lease Agreement amendment,
Landlord may either proceed with the terms of the Lease Agreement as stated
herein, or Landlord may terminate the Lease Agreement with no further
obligation. In this event, Landlord shall return the full amount of the Tenant's
first rental payment which is payable upon execution of this Lease Agreement,
less one-half (1/2) of the amount of Landlord's project design and development
expense; provided, however, Tenant's prorata share shall not exceed $1,600.00.

         In the event that the NASA Related Contract terms are such that Tenant
requires more than 31,114 square feet of rentable area, or less than 27,064
square feet of rentable area initially, to accomplish the scope of work on the
NASA Related Contract, Landlord may terminate this Lease Agreement and neither
party will have any further obligations under this Lease Agreement. In this
event, Landlord shall return the full amount of the Tenant's first rental
payment which is payable upon execution of this Lease Agreement, less one-half
(1/2) of the amount of Landlord's project design and development expense;
provided, however, Tenant's prorata share shall not exceed $1,600.00. This
termination would not preclude Landlord and Tenant from mutually agreeing to a
revision to this Lease Agreement or a new lease agreement for a substantially
smaller or larger lease area than defined in Paragraph 1.

         33. TENANT IMPROVEMENT BUILD-OUT ALLOWANCE. Included in the base rental
is a $16.50 per square foot build-out allowance to be provided by Landlord for
"Tenant Improvements", as indicated on the preliminary architectural drawing
(floor plan) dated October 14, 1992, attached hereto as Exhibit "D" and
incorporated herein by reference, which may be revised as mutually agreed by
Landlord and Tenant before final construction documents are prepared for
construction purposes. If, the cost for the Tenant Improvements exceeds $16.50
per square foot, Tenant shall have the option, in its sole discretion, to
either: (i) mutually agree with Landlord as to the excess cost of the Tenant
Improvements, and equally amortize said excess cost over the first fifty-two
(52) months of the Lease term in addition to the monthly base rental for the
Premises, provided Landlord is able to increase its construction loan and
permanent


                                       21
<PAGE>   22
financing amount; or (ii) pay directly for the excess cost of the Tenant
Improvements over the $16.50 per square foot build-out allowance.

         34. BROKERAGE. Landlord and Tenant each represent that it has not dealt
with any real estate broker or agent in connection with this Lease or its
negotiation other than Cole-Gross Company. Landlord and Tenant shall each
indemnify and hold the other harmless from and against any and all expenses,
judgments and reasonable attorneys' fees incurred in defending the claim of any
other agent or broker who alleges that Landlord or Tenant dealt with him in
connection with this Lease. Landlord shall pay a commission to Cole-Gross
Company in accordance with a separate written commission agreement.

EXECUTED this 30th

         THIS THIRD AMENDMENT TO LEASE AGREEMENT (the "Third Amendment") is
entered into effective as of the 20th day of February, 1997, by and between
J.A. BILLIPP DEVELOPMENT CORPORATION, a Texas corporation (hereinafter referred
to as "Landlord") and JOHNSON ENGINEERING CORPORATION (hereinafter referred to
as "Tenant").

         WHEREAS, Landlord and Tenant entered into that certain Lease Agreement
dated April 30, 1993, as amended by First Amendment to Lease Agreement dated
September 22, 1993, and as amended by Second Amendment to Lease Agreement dated
August 1, 1994 (the "Lease"), demising a portion of the improvements (the
"Premises") located on that certain real property located at 555 Forge River
Drive, in the City of Webster, Harris County, Texas (the "Property"), both the
Premises and the Property being more particularly described in the Lease; and

         WHEREAS, Landlord and Tenant desire to amend the Lease in order to
expand the size of the Premises and to modify certain other terms of the Lease;

         NOW, THEREFORE, based upon the mutual promises and covenants contained
herein and other good and valuable consideration, the receipt and sufficiency
of which is hereby acknowledged, Landlord and Tenant hereby agree as follows:

1.  Approximately 7,890 SF or rentable area ("Second Expansion Area") is added
    to the Premises as of the date of substantial completion of the tenant
    improvements, as documented by Landlord's architect, Munson Kennedy
    Architects. The commencement date for rental payments and all other lease
    obligations relating to the Second Expansion Area shall be the earlier of
    such date of substantial completion or July 15, 1997 ("Second Expansion Area
    Commencement Date"). The Second Expansion Area Commencement Date will be
    confirmed and documented by a separate letter agreement between Landlord and
    Tenant.

2.  The 7,890 SF Second Expansion Area increases the total rentable area of the
    Premises to approximately 39,004 SF.

3.  Attached as Exhibit A to this Third Amendment, is a building floor plan
    showing the delineated 7,890 SF Second Expansion Area, and an approximately
    4,500 SF area marked "Short-term Storage Area" which is contiguous to the
    Second Expansion Area.

4.  Landlord shall provide an allowance of up to One Hundred Thirty-Four
    Thousand Seven Hundred Fifty and No/100 Dollars ($134,750.00) for the
    construction of the tenant improvements within the Second Expansion Area, to
    include all office and technical/storage area finish, heating and air
    conditioning, separate electrical service, mini-blinds, permit fees, sales
    tax costs, etc., in accordance with construction documents mutually approved
    by Landlord and Tenant. Landlord shall provide an additional allowance of
    up to Nine Thousand Eight Hundred Sixty-Two and 50/100 Dollars ($9,862.50)
    for the architectural and engineering

                                       2

<PAGE>   27
     services and construction documents associated with the facility design and
     construction. Upon completion of construction drawings, Landlord agrees to
     competitively bid the tenant improvements construction work to at least two
     (2) qualified general contractors as mutually agreed by Landlord and
     Tenant, one of whom may be selected by Tenant. All contractors must be
     pre-approved by Landlord prior to being allowed to bid on the construction
     contract. Landlord will give Tenant a preliminary estimate of the total
     costs for designing and constructing the tenant improvements associated
     with the Second Expansion Area as soon as possible after preliminary design
     is complete. If the actual total cost of design and construction is greater
     than the sum of the two respective allowances provided, Tenant shall pay to
     Landlord that amount which exceeds the stated allowances within twenty (20)
     days after receipt of Landlord invoice, or as otherwise mutually agreed
     prior to commencement of tenant improvements construction.

5.   The monthly rental as defined in Section 2(a) of the Lease, and as further
     modified in the First Amendment to Lease Agreement and Second Amendment to
     Lease Agreement, shall be increased by Five Thousand Six Hundred Fifty-Five
     and No/100 Dollars ($5,655.00) per month beginning on the Second Expansion
     Area Commencement Date. Any partial month will be prorated based upon the
     number of days then remaining in the month. Thereafter, the total monthly
     rental for the 39,004 SF will be Twenty-Nine Thousand Seven Hundred
     Sixty-Nine and No/100 Dollars ($29,679.00) per month for the current lease
     term period through October 31, 1998, and Thirty-One Thousand Five Hundred
     Eighty-Five and No/100 Dollars ($31,585.00) per month for the period
     November 1, 1998 through June 30, 2003.

6.   Landlord shall provide, at Landlord's sole cost, a thirty-foot (30')
     flagpole to be located as mutually agreed by Landlord and Tenant in the
     vicinity of the parking area near the Tenant main entry to the building, of
     which the Premises is a part. The single flagpole and U.S. Flag will be
     comparable to the flagpoles located at the east end of the building.

7.   Tenant shall have the use of the Short-term Storage Area at no charge until
     such time as this area is either leased to Tenant on a longer-term basis,
     or is leased to a third-party tenant, or is otherwise required for use by
     Landlord. Landlord shall give Tenant at least thirty (30) days prior
     written notice before requiring Tenant to vacate the Short-term Storage
     Area. At any time prior to such notice, Landlord and Tenant may agree to a
     longer-term lease of all or a portion of the Short-term Storage Area as
     may be available, with lease terms to be mutually agreed at the time of the
     lease expansion. Until such formal lease agreement amendment incorporates
     all or a portion of the Short-term Storage Area within the total rentable
     area of the Premises, this Short-Term Storage Area is provided "as-is" and
     with no services, warranties, or finish to be provided by Landlord. Tenant
     shall make no alterations or improvements in the Short-term Storage Area
     without prior written approval from Landlord.

8.     In the event that Tenant exercises its right to terminate the Lease
       pertaining to the expanded 39,004 SF Lease Premises, under the conditions
       and procedures outlined in Paragraph 28 of the Lease Agreement, Tenant
       shall nevertheless be obligated to make all lease payments and expenses
       reimbursements (to include Tenant's proportionate share of property
       taxes, insurance, common area maintenance ["CAM"] costs) for the Second
       Expansion Area for a minimum of thirty-six (36) months after the Second
       Expansion Area Commencement Date.

9.     Except as expressly provided herein, all other terms, covenants and
       conditions of the Lease shall remain the same, in full force and effect,
       and are hereby ratified and confirmed by Landlord and Tenant.

EXECUTED effective as of the date first written above.

     completed by Landlord, but not later than April 1, 1998 unless mutually

       facility design and construction ("A & E Allowance Provided by
       Landlord"). Upon completion of construction drawings, Landlord agrees to
       competitively bid the tenant improvements construction work to at least
       two (2) qualified general contractors. If the actual total cost of design
       and construction is greater than the total sum of the Standard Tenant
       Finish Allowance Provided by Landlord and the A & E Allowance Provided by
       Landlord ("Over Allowance Cost"), Tenant shall pay to Landlord the Over
       Allowance Cost within twenty (20) days after receipt of Landlord invoice,
       or as otherwise mutually agreed prior to commencement of tenant
       improvement construction.

6.     Within five (5) days after the construction cost bid amounts are given to
       Tenant by Landlord, Tenant may elect to have Landlord provide an
       additional Fifty Thousand and No/100 Dollars ($50,000.00) tenant finish
       allowance ("Additional $50,000.00 Landlord Allowance") which would
       decrease the payment due Landlord for the Over Allowance Cost described
       in Paragraph 5 above by Fifty Thousand and No/100 Dollars ($50,000.00)
       and would concurrently increase the base monthly rental as described
       below.

7.     The monthly rental as defined in Section 2(a) of the Lease, and as
       further modified in the First Amendment to Lease Agreement, Second
       Amendment to Lease Agreement, and Third Amendment to Lease Agreement
       ("Prior Base Monthly Rental"), shall be increased as follows beginning on
       the Third Expansion Area Commencement Date. Any partial month rentals due
       for the Third Expansion Area will be prorated based upon the number of
       days then remaining in the month.

This Lease Agreement made and entered into on this the 19th day of February,
1998, between Nassau Development Company, "Lessor" whose address for purposes
hereof is 18100 Upper Bay Road, Suite A, Houston, Texas 77058, acting by and
through its duly authorized representative, and Johnson Engineering Inc.,
"Lessee" whose address in Houston, Texas, for purposes hereof is 18100 Upper Bay
Road, Suite 207, Houston, Texas 77058.


                              W I T N E S S E T H:

                                       I.

I.A      LEASED PREMISES

(1) Subject to and upon the terms, provisions and conditions hereinafter set
forth, and each in consideration of the duties, covenants and obligations of the
other hereunder, Lessor has leased, demised and rented to Lessee the following
described premises, suites 204, 207 and 220 (herein referred to as "Leased
Premises") which is a total of 3,952 rentable square feet, situated in B. XII,
the "Building," located at 18100 Upper Bay Road, Suite 207, Houston, Harris
County, Texas.

(2) The number of square feet of gross rentable area comprising the building of
which the Leased Premises are situated in shall be 24,148 square feet unless
enlarged or reduced by written amendment or addendum hereto.

                                      II.

II.A     TERM

Subject to and upon the terms and conditions set forth herein, or in any exhibit
or addendum hereto, this lease shall continue in force for a term of one year,
beginning on the 1st of March, 1998. This Lease will expire on February 28,
1999.

II.B     USE

The Leased Premises are to be used and occupied by Lessee solely for the
purposes of conducting its business of aerospace engineering. Provided, however,
that Lessee may



<PAGE>   4
not use the Leased Premises in such a way as to interfere with
the use and enjoyment of other tenants or which is otherwise inconsistent with
the terms of this Agreement.

II.C     BASE RENTAL RATE

The base rental shall be $9.60 per square foot per year ($.80 per square foot
per month) for each square foot of gross rentable area then being leased by
Lessee under the terms and provisions hereof. ($3,161.60 Dollars of Rent per
Month).

II.D     SECURITY DEPOSIT

[text cut off] Lessee shall timely discharge in full all its obligation under
this Agreement, the security deposit shall be returned to Lessee thirty (30)
days after the expiration of the term of this Agreement. In the event of
transfer of this Agreement by Lessor, Lessor shall have the right to transfer
the security deposit to the transferee in which event Lessor shall have no
further obligation to Lessee for return of the security deposit.

II.E     RENTAL ESCALATION

(1) The term "Lease Year," as used herein, shall mean the fiscal year ending
March 31 of the year in which this Lease Agreement is entered into and any
subsequent fiscal year(s) during the initial term hereof and any extensions or
renewals hereof. In any Lease Year in which the Basic Costs (as defined in
paragraph II.F below) for maintaining and operating the Building, of which the
leased premises are a part, exceed the amount of FIVE AND 00/100 Dollars ($5.00)
per square foot of rentable area then leased by Lessee for that year (the "Base
Stop"), Lessee shall pay as additional rent the amount equal to Lessee's
proportionate share of the amount of the Basic Costs that exceed the Base Stop.
Lessee's "proportionate share" of the amount of Basic Costs that exceed the Base
Stop shall be the same percentage of the amount of Basic Costs over the Base
Stop as is equal to the percentage which the gross rentable area then leased by
Lessee in the Building bears to the total gross rentable area contained in the
Building.

(2) Lessor may submit to Lessee, and Lessee agrees to pay, a bill or invoice as
frequently as each month for one-twelfth (1/12) of the estimated annual amount
as may be ascertained by Lessor to be due by Lessee under this Article.
Alternatively, Lessor may submit to Lessee (at Lessor's sole discretion), and
Lessee agrees to pay, a bill or invoice as frequently as each month for the
actual increase in Basic Costs over the amount of the Base Stop for that month
and any preceding months for which rental escalation is due under this Article.
In the event of such billing or invoicing as provided hereunder by Lessor,
Lessee agrees and covenants to pay such additional amount contemporaneously with
the Base Rental on the first day of each calendar month, monthly in advance.

(3) Following the close of each Lease Year, Lessor shall determine the Basic
Costs for such Lease Year and give written notice thereof to Lessee which notice
shall also contain or be accompanied by a computation of additional rental, if
any, paid by Lessee as above provided and the balance, if any, then owing by
Lessee. In the event a balance is owing

                                       2

<PAGE>   5
by Lessee, same shall be paid by Lessee within ten (10) days of such notice. In
the event the computation for such Lease Year reflects a negative balance, same
shall be refunded by Lessor to Lessee within ten (10) days of such notice
provided that in no event shall the rental to be paid by Lessee for the leased
premises during the term of this Lease Agreement, and any extensions or renewals
hereof, ever be less than the base rental stated in Paragraph II.C of this Lease
Agreement. Lessee shall receive no benefit for a decrease in Basic Costs or the
amount of Basic Costs below the Base Stop for any calendar or fiscal year, or
any part thereof, during the term of this Lease Agreement, or any extensions and
renewals thereof. For the last Lease Year, Lessee shall only pay for such Lease
Year that portion of its proportionate share of the amount of Basic Costs that
exceed the Base Stop as the number of calendar days in the last Lease Year that
this Lease Agreement is in effect bears to 365.

II.F     BASIC COSTS FOR ESCALATION

(1) "Basic Costs" as said term is used herein shall consist of the operating
expenses of the Building, which shall be computed on the accrual basis. All
operating expenses shall be determined in accordance with generally accepted
accounting principles which shall be consistently applied. The term "operating
expenses" as used herein shall mean all expenses, costs and disbursements (but
not replacement of capital investment items) of every kind and nature which

                  assessments attributable to the Building or its operation
                  excluding, however, federal and state taxes on income.

    (g)           Cost of repairs and general maintenance. (The costs of repairs
                  and general maintenance shall exclude alterations attributable
                  solely to tenants of the Building other than Lessee.)

    (h)           Management fees not to exceed five (5%) percent of the base

(2) Lessee at its expense shall have the right at all reasonable times to audit
Lessor's book and records relating to this lease for any year or years for which
additional rental payments become due.

demand. Additional rental for Lessee's share of Lessor's increased costs in
accordance with the escalation formula shall be due and payable quarterly as

         (a)    Hot and cold water at those points of supply provided for
                general use of other tenants in the Building, central heat and
                air conditioning in season, at such times as Lessor normally
                furnishes these services to other tenants in the Building, and
                at such temperatures and in such amounts as are considered by
                Lessor to be standard, such service on Saturdays, Sundays and
                legal holidays to be furnished only upon the request of Lessee,
                who


                                       4

<PAGE>   7
                shall bear the entire cost thereof; janitorial service on a
                five (5) day week basis, electric lighting service for all
                public areas and special service areas of the Building in the
                manner and to the extent deemed by Lessor to be standard; but
                failure by Lessor to any extent to furnish these defined
                services, or any cessation thereof, resulting from causes beyond
                the control of Lessor, shall not render Lessor liable in any
                respect for damages to either person or property, not be
                construed as an eviction of Lessee, nor work an abatement of
                rent, nor relieve Lessee from fulfillment of any covenant
                or agreement hereof.  Should any of the equipment or machinery
                break down, or for any cause cease to function properly, Lessor
                shall use reasonable diligence to repair same promptly, but
                Lessee shall have no claim for rebate of rent or damages on
                account of any interruptions in service occasioned thereby or
                resulting therefrom.

    (b)         Proper electrical facilities to furnish sufficient power for
                typewriters, voice writers, calculating machines and other
                machines of similar low electrical consumption; provided,
                however, that Lessee shall bear the utility costs, air
                conditioning costs and costs to install appropriate meters to
                determine such costs occasioned by electro-data processing
                machines and similar machines of high electrical consumption.
                Such machines of high electrical consumption shall not be
                installed within the Building without the prior written
                consent of Lessor.

III.B    PEACEFUL ENJOYMENT

(1) Lessee shall, any may peacefully have, hold and enjoy the Leased Premises,
subject to the other terms hereof, provided that Lessee pays the rental herein
recited and performs all of its covenants, duties and agreements herein
contained.

at the times and in the manner herein provided.

IV.B     REPAIRS BY LESSOR

Premises during the term of this lease, except such repairs as may be required

repairs to walls, floors, corridors, windows, and other structures and Building
equipment within and serving the Leased Premises, and such additional
maintenance as may be necessary because of damages by persons other than Lessee,
its invites, visitors, or anyone acting at its direction or on its behalf; and
as may be necessary solely because of the negligence of Lessor at its expense
beginning not more than fifteen (15) days after written notice thereof by
Lessee.

IV.C     REPAIRS BY LESSEE
(1) At its own cost and expense, Lessee shall repair or replace any damage or
injury done to the Building, or any part thereof, caused by Lessee, its agents,
employees, invitees, or visitors; provided however, if Lessee fails to make such
repairs or replacements promptly Lessor may, at its option, make such repairs or
replacements, and Lessee shall repay the costs thereof to Lessor on demand.
Lessee's indemnity obligation hereunder shall survive regardless of whether
Lessor is or is alleged to have caused or contributed to such damages through
its actions or interactions constituting negligence, or giving rise to strict
liability or statutory liability. Lessee agrees to keep the Leased Premises and
the Building free at all times of any mechanics' and materialmen's liens or
other liens arising from such repair or replacement, including, but not limited
to, posting bond to obtain a release of any such lien.

IV.D     CARE OF THE LEASED PREMISES

(1) Lessee shall not commit or allow any waste or damage to be committed on any
portion of the Leased Premises, and at the termination of this lease, by lapse
of time or otherwise, shall deliver up said Leased Premises to Lessor in as good
condition as at date of original possession by Lessee, ordinary wear and tear
excepted, and upon such termination of this lease, Lessor shall have the right
to re-enter and resume possession of the Leased Premises.

IV.E     ASSIGNMENT OR SUBLEASE

(1) Lessee shall not assign this Agreement or sublet the Leased Premises, or any
part thereof, without first obtaining the written consent of Lessor, however
Lessor agrees that it will not unreasonably or arbitrarily refuse to give such
permission or consent. No assignment or sublease of the Leased Premises shall be
valid or binding upon Lessor without such consent. In no event shall any such
assignment or sublease ever release Lessee from any obligation or liability
hereunder.

IV.F     ALTERATIONS, ADDITIONS AND IMPROVEMENTS

(1) Lessee shall not permit the Leased Premises to be used for any other purpose
than that stated in the use clause hereof, or make or allow to be made any
alterations [text cut off].

(2) The cost of any alterations, physical additions, or improvements shall be
borne and paid for solely by Lessee. Lessee agrees to keep the Leased Premises
and the Building free at all times of any mechanics' and materialmen's liens or
other liens arising from such alterations, physical additions or improvements
including, but not limited to, posting a bond to obtain a release of any such
lien. Lessor shall have the right to insist on adequate security by way of
insurance, bonding or other means, prior to any modification or alteration to
ensure compliance with this clause.


                                       6


<PAGE>   9
(3) Though all alterations, physical additions, or improvements made by Lessee
become the property of Lessor upon the termination of this lease, Lessor may
require that Lessee remove any or all alterations, additions, and improvements
installed or made by Lessee, and any other property placed on the premises by
Lessee, upon termination of the lease. In the event that Lessor requires Lessee
to remove all such alterations, additions, or improvements, Lessee shall bear
and pay the cost of such removal and shall repair any damage to the premises
caused by such removal and, absent express written permission of Lessor, to
restore the Leased Premises to its original condition, reasonable wear and tear
excepted.

IV.G     LEGAL USE AND VIOLATIONS OF INSURANCE COVERAGE

(1) Lessee shall not occupy or use, or permit any portion of the Leased Premises
to be occupied or used for any business or purpose which is unlawful,
disreputable or deemed to be extra-hazardous on account of fire, or permit
anything to be done which would in any way increase the rate of fire insurance
coverage on said Building and/or its contents.

IV.H     LAWS AND REGULATIONS; RULES OF BUILDING

(1) Lessee shall comply with all laws, ordinances, orders, rules and regulations
(state, federal, municipal and other agencies or bodies having any jurisdiction
thereof) relating to the use, condition or occupancy of the Leased Premises.
Lessee will comply with the rules of the Building adopted by Lessor which are
set forth as Exhibit "B" attached hereto to be initialed by the parties hereto,
and made a part hereof as fully as though set forth herein. Lessor shall have
the right at all times to change such rules and regulations or to amend them in
any reasonable manner as may be deemed advisable by Lessor for the safety, care
and cleanliness of the Leased Premises and for preservation of good order
therein, all of which changes and amendments will be sent by Lessor to Lessee in
writing and shall be thereafter carried out and observed by Lessee.

IV.I     ENTRY FOR REPAIRS AND INSPECTION

(1) Lessee shall permit Lessor, its agents or representatives to enter into and
upon any part of the Leased Premises at all reasonable hours to inspect same or
to clean, make repairs, alterations or additions thereto, as Lessor may deem
necessary or desirable, and Lessee shall not be entitled to any abatement or
reduction of rent by reason thereof.

IV.J     NUISANCE

(1) Lessee shall conduct its business and control its agents, employees,
invitees, and visitors in such manner as not to create any nuisance, or
interfere with, annoy or disturb any other tenant or Lessor in his operation of
the Building.

IV.K     ASSIGNMENT

(1) Lessor shall have the right to transfer and assign, in whole or in part, all
of its rights and


                                       7

<PAGE>   10
IV.L     DEFAULT

(1) Default on the part of the Lessee on paying said rent or any installment
thereof, as herein above provided, or default on Lessee's part in keeping or
performing any other term, covenant or condition of this lease such as to create
a breach thereof, shall authorize Lessor, at its sole option at any time after
such default, and after ten (10) days' written notice thereof to Lessee, to
declare this lease terminated, and upon the occurrence of any one or more of
such defaults, Lessor immediately, or at any time thereafter, may re-enter said
premises and remove all persons therefrom with or without legal process, and
without prejudice to any of its other legal rights. All claims for damages by
reason of such re-entry are expressly waived, as also are all claims for damages
by reason of any distress warrants or proceedings by way of sequestration which
Lessor may employ to recover said rents or possession of said premises;
provided, that Lessor shall not have the right to declare this lease terminated,
if, within ten (10) days after notice of any default, Lessee corrects the
default. Provided, however, that nothing herein shall restrict Lessor's rights
at law or equity to recover possession of the Leased Premises in the event of
multiple or repeated defaults, if consistent with the laws of this state.

(2) If Lessee defaults, Lessor shall be entitled to recover damages, including,
but not limited to, the total of all payments owing and unpaid as of the date of
the default, plus interest from the date due until paid at the greatest possible
non-usurious rate permitted by law (provided that if no usury statute shall
apply, past due rent and other payments shall bear interest at eighteen percent
(18%) per annum from the due date until paid); the costs of re-entry and
reletting, including without limitation the cost of any clean-up, reasonable
refurbishing, removal of Lessee's property and fixtures; other expenses caused
by Lessee's failure to quit the premises and leave the same in the required
condition; reasonable attorney's fees, including those incurred at trial and all
appeals; court costs; expert witness fees; advertising costs; and the difference
between (i) the annual base rent and all of Lessee's other obligations under
this lease and (ii) the actual annual base rent received by the landlord for the
period commencing with the date of the default and continuing through the
termination date. Damages shall survive the termination of this lease.

(3) Pursuit of any of the above-stated remedies by Lessor after a default by
Lessee shall not preclude pursuit of any other remedies provided in this lease
or applicable law, nor shall pursuit of any remedy constitute a forfeiture or
waiver of any payment due to Lessor.

IV.M     WAIVER

(1) Failure of Lessor to declare any default immediately upon occurrence
thereof, or delay in taking any action in connection therewith, shall not waive
such default, but Lessor shall have the right to declare any such default at any
time and take such action as might be lawful or authorized hereunder, either in
law or in equity.

<PAGE>   11
IV.N     BANKRUPTCY BY LESSEE

(1) If voluntary bankruptcy proceedings are instituted by Lessee, or if Lessee
is adjudged a bankrupt, or if Lessee makes an assignment for the benefit of its
creditors, or if execution is issued against it, or if the interest of Lessee
hereunder passes by operation of law to any person other than Lessee, this lease
may, at the option of Lessor, be terminated by notice mailed by registered mail
and addressed to Lessee.

IV.O     AD VALOREM TAXES

(1) Lessor shall pay all ad valorem taxes which accrue against the Building
during the term of this lease. Lessee shall pay all ad valorem and similar taxes
levied upon or applicable to all personal property within the Leased Premises
and improvements in excess of building standard improvements.

IV.P     CASUALTY INSURANCE

(1) Lessor shall, at all times during the term of this lease, at its expense,
maintain a policy or policies of insurance issued by and binding upon some
insurance company, insuring the Building against loss or damage by fire,
explosion, or other hazards and contingencies for the full insurable value
thereof; provided that Lessor shall not insure any goods, property, or supplies
not owned by Lessor and/or covered lease which Lessee may bring or obtain upon
the Leased Premises, or any additional improvements which Lessee may construct
thereon. If the annual premiums charged Lessor for such casualty insurance
exceed the standard premium rates because the nature of Lessee's operation
results in extra-hazardous exposure, then Lessee shall upon receipt of
appropriate premium invoices reimburse Lessor for any such increases covering in
such premiums.

(2) Lessee shall be responsible for providing, at Lessee's own expense, all
insurance coverage necessary for protection against loss or damage from fire,
theft, or other casualty of Lessee's goods, furniture, leasehold improvements,
equipment, files and all other property placed in the Leased Premises and
liability insurance covering the Leased Premises.

IV.Q     INDEMNITY

(1) Lessee agrees to and does hereby hold harmless and unconditionally indemnify
Lessor, its agent, officers, directors, employees, representatives, invitees,
guests, and contractors (collectively referred to in this paragraph as "Lessor")
against and for all costs, expenses, claims, liability, and damages of every
nature (including, but not limited to attorney's fees, court costs, expert
witness fees and interest) which Lessor may at any time suffer, sustain or
become liable for by reason of any and all accidents, damages, losses or
injuries resulting in personal injury, death and/or loss of or damage to any
property in any manner arising from or related to, in whole or in part, the
presence, conduct of business or any act or omission of Lessee, its agents,
officers, directors, employees, representatives, invitees, guests, contractors
or any parties contracting or conducting business with Lessee. Lessee agrees to
hold Lessor harmless for such costs,


                                       9


<PAGE>   12
expenses, claims, liability and damages even if same arise or are alleged to
arise in any manner from any negligent act or omission of Lessor, or any act for
which Lessor could be liable under theories of strict or statutory liability,
excepting only that arising from the sole negligence of Lessor. In case of any
action or proceeding brought against Lessor by reason of such claim, Lessee,
upon notice from Lessor, shall defend such action or proceeding by counsel of
Lessor's own choosing.

                                       V.

V.A      CONDEMNATION AND LOSS OR DAMAGE

(1) If the Leased Premises shall be taken or condemned in whole or in part for
any public purpose, this lease shall, at the option of either party, forthwith
cease and terminate; and Lessor or Lessee shall not be liable or responsible to
each other for any loss or damage to any property or person occasioned by theft,
fire, act of God, public enemy, injunction, riot, strike, insurrection, war,
court order, requisition, or order of [text cut off on bottom of page]
governmental body or authority beyond the control of Lessor or Lessee, as the
case may be, or for any damage or inconvenience which may arise through repair
or alteration of any part of the Building, or failure to make any such repairs,
or from any cause whatever, unless caused solely by Lessor's or Lessee's gross
negligence, as the case may be, except as may be herein otherwise expressly
provided.

V.B      LESSOR'S LIEN FOR RENT

(1) Lessor shall have, at all times, a valid security interest to secure payment
of all rentals and other sums of money becoming due under this Lease from
Lessee, and to secure payment of any damages or loss that Lessor may suffer by
reason of the breach by Lessee of any covenant, agreement or condition contained
in this Lease, upon all goods, wares, equipment, fixtures, furniture, and other
personal property of Lessee which is now on the premises or which is placed on
the premises at some later date, and all proceeds from them. This property shall
not be removed from the premises without the consent of Lessor until all
arrearages in rent and all other sums of money then due to Lessor under this
Lease have been paid and discharged, and all the covenants, agreements, and
conditions of this Lease have been fully complied with and performed by Lessee.
Upon the occurrence of an event of* default by Lessee, Lessor may, in addition
to any other remedies provided in this Lease or by law, after giving reasonable
notice of the intent to take possession and giving an opportunity for a hearing
on the issue, enter upon the premises and take possession of any and all goods,
wares, equipment, fixtures, furniture, and other personal property of Lessee
situated on the premises without liability for trespass or conversion, and sell
the same at public or private sale, with or without having the property at the
sake, after giving Lessee reasonable notice of the time and place of

*    Upon the occurrence of an event of default by Lessee, Lessor shall not take
     possession of any government owned goods, wares, equipment, furniture, and
     other kinds of government property situated on the premises.


                                       10

<PAGE>   13
any public sale or of the time after which any private sale is to be made.
Lessor or its assigns may purchase any items to be sold at such a sale unless
they are prohibited from doing so by law. Unless otherwise provided by law, and
without intending to exclude any other manner of giving Lessee reasonable
notice, the requirement of reasonable notice shall be met if such notice is
given at least twenty-one (21) days before the time of the sale. The proceeds
from any such dispositions, less any and all expenses connected with the taking
of possession, holding and selling of the property (including reasonable
attorney's fees and other expenses), shall be applied as a credit against the
indebtedness secured by the security interest granted in this section. Any
surplus shall be paid to Lessee or as otherwise required by law; and Lessee
shall pay any deficiencies immediately. Upon request by Lessor, Lessee agrees to
execute and deliver to Lessor a financing statement in form sufficient to
perfect the security interest of Lessor in the aforementioned property and
proceeds under the provisions of the Uniform Commercial Code in force in the
State of Texas. The statutory lien for rent is not waived, the security interest
granted in this article being in additions and supplementary, to that lien.

V.C      ABANDONMENT

(1) In the event the Leased Premises are abandoned by Lessee, Lessor shall have
the right, but not the obligation, to relet same for the remainder of the term
provided for herein; and if the rent received through such reletting does not at
least equal the rent provided for herein, Lessee shall pay and satisfy any
deficiency between the amount of the rent so provided for and that received
through reletting, and, in addition thereto, shall pay all expenses incurred in
connection with any such reletting, including, but not limited to, the cost of
restoring premises to its prior condition. Nothing herein shall be construed as
in any way denying Lessor the right in the event of abandonment of said premises
or other breach of this Agreement by Lessee, to treat the same as an entire
breach and at Lessor's option immediately sue for the entire breach of this
Agreement and any and all damages which Lessor suffers thereby.

V.D      HOLDING OVER

(1) In the event of holding over by Lessee after expiration of termination of
this lease, Lessee shall pay as liquidated damages double rent on a per diem
basis, for the entire holdover period. No holding over by Lessee after the term
of this lease, either with or without consent and acquiescence of Lessor, shall
operate to extend the lease for a longer period than one (1) month; and any
holding over with the consent of Lessor in writing shall thereafter constitute
this lease a lease from month to month.

V.E      FIRE CLAUSE

(1) In the event of a fire in the Leased Premises, Lessee shall immediately give
notice thereof to Lessor, if the Leased Premises, through no fault or neglect of
Lessee, its agents, employees, invitees or visitors, shall be partially
destroyed by fire or other casualty so as to render the premises untenantable,
the rental herein shall cease thereafter until such time as the Leased Premises
are made tenantable by Lessor. In the event of the total destruction of the
Leased Premises without fault or neglect of Lessee, its agents,


                                       11

<PAGE>   14
employees, invitees or visitors, or if from such cause the same shall be so
damaged that Lessor shall decide not to rebuild, then all rent owed up to the
time of such destruction or termination shall be paid by Lessee and thenceforth
this lease shall cease and come to an end. If such damage is due to the fault or
neglect of Lessee, then all repairs shall be at Lessee's expense and there shall
be no abatement of rent. This obligation shall survive regardless of whether
Lessor is or is alleged to be concurrently negligent in connection with said
damages.

V.F      ESTOPPEL CERTIFICATE

(1) The Lessee agrees, at any time and from time to time, upon not less than
fifteen (15) business days' prior notice from the Lessor, to execute,
acknowledge and deliver to the Lessor a statement in writing (1) certifying that
this Lease is unmodified and in full force and effect (or if there have been
modifications, that this Lease is in full force and effect as modified and
stating the modifications); (2) stating the dates to which the rent and other
charges hereunder have been paid by the Lessee; (3) stating whether or not the
Lessee has knowledge that the Lessor is in default in the performance of any
covenant, agreement or condition contained in this Lease, and, if the Lessee has
knowledge of such a default, specifying each such default and (4) stating the
address to which notices to the Lessee shall be sent. Prior to the commencement
of or during the term of this Lease the Lessor shall, if requested by the
Lessee, deliver an estoppel certificate, in the substance and form described
above, relative to the status of this Lease and/or any ground lease, underlying
lease and/or mortgage encumbering the building, parking facility or land.

V.G      ATTORNEY'S FEE

(1) In the event Lessee makes default in the performance of any of the terms,
covenants, agreements or conditions contained in this lease such as to create a
breach thereof, and Lessor places the enforcement of this lease, or any part
thereof, or the collection of any rent due, or to become due hereunder, or
recovery of the possession of the Leased Premises in the hands of an attorney,
or files suit upon the same, Lessee agrees to pay Lessor its reasonable
attorney's fees, court costs, expert witness fees, and other costs of collection
as may be reasonably incurred by Lessor.

V.H      ALTERATION

(1) Lessor and Lessee agree that this Agreement supersedes all prior oral or
written agreements and may not be altered, changed or amended, except by an
instrument in writing, signed by both parties hereto.

V.I      WAIVER OF SUBROGATION RIGHTS

(1) Anything in this lease to the contrary notwithstanding, Lessee hereto hereby
waives any and all rights of recovery, claim, action or cause of action, against
Lessor, its agents, officers, employees and representatives for any loss or
damage that may occur to the premises hereby demised, or any improvements
thereto, or said Building of which the Leased Premises are a part, or any
improvements thereto, by reason of fire, the elements,


                                       12

<PAGE>   15
or any other cause which could be insured against under the terms of
standard fire and extended coverage or liability insurance policies, regardless
of cause or origin, including negligence, strict liability or statutory
liability of the Lessor, its agents, officers, employees and representatives.

V.J      NOTICES

(1) Any and all notices or other communication required or permitted by this
lease to be served on or given to either party to this lease by the other party
hereto shall be in writing and shall be deemed duly served and given when
personally delivered to the party to whom it is directed, or in lieu of such

This Lease Agreement made and entered into on this the 26th day of January,

II.B     USE

The Leased Premises are to be used and occupied by Lessee solely for the

the terms of this Agreement.


<PAGE>   20
II.C     BASE RENTAL RATE

The base rental rate shall be $9.60 per square foot per year ($.80 per square
foot per month) for each square foot of gross rentable area then being leased by
Lessee under the terms and provisions hereof. ($2,366.40 Dollars of Rent per
Month).

II.D     SECURITY DEPOSIT

Lessee has deposited with Lessor the sum of TWO THOUSAND THREE HUNDRED SIXTY SIX
& 40/100 DOLLARS ($2,366.40) as security for the faithful performance by Lessee
of its obligations under this Lease Agreement. In the event Lessee defaults in
any of its obligations hereunder, it is agreed Lessor, at its option without
notice to Lessee may use, apply or retain the whole or any part of the funds so
deposited as security to the extent required to discharge any such obligation of
Lessee and in the event such sum shall be insufficient to discharge such
obligation, Lessee shall remain liable for the balance of any such sum remaining
after application of the security deposit. In the event Lessee shall timely
discharge in full all its obligation under this Agreement, the security deposit
shall be returned to Lessee thirty (30) days after the expiration of the term of
this Agreement. In the event of transfer of this Agreement by Lessor, Lessor
shall have the right to transfer the security deposit to the transferee in which
event Lessor shall have no further obligation to Lessee for return of the
security deposit.

II.E     RENTAL ESCALATION

(1) The term "Lease Year", as used herein, shall mean the fiscal year ending
March 31 of the year in which this Lease Agreement is entered into and any
subsequent fiscal year(s) during the initial term hereof and any extensions or
renewals hereof. In any Lease Year in which the Basic Costs (as defined in
paragraph II.F below) for maintaining and operating the Building, of which the
leased premises are a part, exceed the amount of FIVE AND XX/100 Dollars ($5.00)
per square foot of rentable area then leased by Lessee for that year (the "Base
Stop"), Lessee shall pay as additional rent the amount equal to Lessee's
proportionate share of the amount of the Basic Costs that exceed the Base Stop.
Lessee's "proportionate share" of the amount of Basic Costs that exceed the Base
Stop shall be the same percentage of the amount of Basic Costs over the Base
Stop as is equal to the percentage which the gross rentable area then leased by
Lessee in the Building bears to the total gross rentable area contained in the
Building.

(2) Lessor may submit to Lessee, and Lessee agrees to pay, a bill or invoice as
frequently as each month for one-twelfth (1/12) of the estimated annual amount
as may be ascertained by Lessor to be due by Lessee under this Article.
Alternatively, Lessor may submit to Lessee (at Lessor's sole discretion), and
Lessee agrees to pay, a bill or invoice as frequently as each month for the
actual increase in Basic Costs over the amount of the Base Stop for that month
and any preceding months for which rental escalation is due under this Article.
In the event of such billing or invoicing as provided hereunder by Lessor,
Lessee agrees, and covenants to pay such additional amount contemporaneously
with the Base Rental on the first day of each calendar month, monthly in
advance.


                                       2

<PAGE>   21
(3) Following the close of each Lease Year, Lessor shall determine the Basic
Costs for such Lease Year and give written notice thereof to Lessee which notice
shall also contain or be accompanied by a computation of additional rental, if
any, paid by Lessee as above provided and the balance, if any, then owing by
Lessee. In the event a balance is owing by Lessee, same shall be paid by Lessee
within ten (10) days of such notice. In the event the computation for such Lease
Year reflects a negative balance, same shall be refunded by Lessor to Lessee
within ten (10) days of such notice provided that in no event shall the rental
to be paid by Lessee for the leased premises during the term of this Lease
Agreement, and any extensions or renewals hereof, ever be less than the base
rental stated in Paragraph II.C of this Lease Agreement. Lessee shall receive no
benefit for a decrease in Basic Costs or the amount of Basic Costs below the
Base Stop for any calendar or fiscal year, or any part thereof, during the term
of this Lease Agreement, or any extensions and renewals thereof. For the last
Lease Year, Lessee shall only pay for such Lease Year that portion of its
proportionate share of the amount of Basic Costs that exceed the Base Stop as
the number of calendar days in the last Lease Year that this Lease Agreement is
in effect bears to 365.

<PAGE>   23
               such times as Lessor normally furnishes these services to
               other tenants in the Building, and at such temperatures and in
               such amounts as are considered by Lessor to be standard, such
               service on Saturdays, Sundays and legal holidays to be furnished
               only upon the request of Lessee, who shall bear the entire cost
               thereof; janitorial service on a five (5) day week basis,
               electric lighting service for all public areas and special
               service areas of the Building in the manner and to the extent
               deemed by Lessor to be standard; but failure by Lessor to any
               extent to furnish these defined services, or any cessation
               thereof, resulting from causes beyond the control of Lessor,
               shall not render Lessor liable in any respect for damages to
               either person or property, nor be construed as an eviction of
               Lessee, nor work an abatement of rent, nor relieve Lessee from
               fulfillment of any covenant or agreement hereof. Should any of
               the equipment or machinery break down, or for any cause cease to
               function properly, Lessor shall use reasonable diligence to
               repair same promptly, but Lessee shall have no claim for rebate

               machines of similar low electrical consumption; provided,
               however, that Lessee shall bear the utility costs, air
               conditioning costs and costs to install appropriate meters to

               Such machines of high electrical consumption shall not be
               installed within the Building without the prior written consent
               of Lessor.

III.B    PEACEFUL ENJOYMENT

damages by persons other than Lessee, its invites, visitors, or anyone acting at

injury done to the Building, or any part thereof, caused by Lessee, its agents,

such repairs or replacements promptly Lessor may, at its option, make such
repairs or replacements, and Lessee shall repay the costs thereof to Lessor on
demand. Lessee's indemnity obligation hereunder shall survive regardless of
whether Lessor is or is alleged to have caused or contributed to such damages
through its actions or interactions constituting negligence, or giving rise to
strict liability or statutory liability. Lessee agrees to keep the Leased

termination of this lease by lapse of time or otherwise; provided, however, this
clause shall not apply to moveable equipment or furniture owned by Lessee.

become the property of Lessor upon the termination of this lease, Lessor may
require that Lessee remove any or all alterations, additions, or improvements

Lessee will comply with the rules of the Building adopted by Lessor which are
set forth as Exhibit "B" attached hereto to be initialed by the parties hereto,

IV.J     NUISANCE

declare this lease terminated, and upon the occurrence of any one or more of
such defaults, Lessor immediately, or at any time thereafter may re-enter said
premises and remove all persons therefrom with or without legal process, and
without prejudice to any of its other legal rights. All claims for damages by
reason of such re-entry are expressly waived, as also are all claims for damages
by reason of any distress warrants or proceedings by way or sequestration which
Lessor may employ to recover said rents or possession of said premises;
provided, that Lessor shall not have the right to declare this lease terminated
if within ten (10) days after notice of any default, Lessee corrects the
default. Provided, however, that nothing herein shall restrict Lessor's rights
at law or equity to recover possession of the Leased Premises in the event of
multiple or repeated defaults, if consistent with the laws of this state.

(2) If Lessee defaults, Lessor shall be entitled to recover damages, including,
but not limited to, the total of all payments owing and unpaid as of the date of

<PAGE>   27
(3) Pursuit of any of the above-stated remedies by Lessor after a default by
Lessee shall not preclude pursuit of any other remedies provided in this lease
or applicable law, nor shall pursuit of any remedy constitute a forfeiture or
waiver of any payment due to Lessor.

IV.M     WAIVER

(1) Failure of Lessor to declare any default immediately upon occurrence
thereof, or delay in taking any action in connection therewith, shall not waive
such default, but Lessor shall have the right to declare any such default at any
time and take such action as might be lawful or authorized hereunder, either in
law or in equity.

IV.N     BANKRUPTCY BY LESSEE

(1) If voluntary bankruptcy proceedings are instituted by Lessee, or if Lessee
is adjudged a bankrupt, or if Lessee makes an assignment for the benefit of its
creditors, or if execution is issued against it, or if the interest of Lessee

thereof, provided that Lessor shall not insure any goods, property, or supplies
not owned by Lessor and/or covered lease which lessee may bring or obtain upon
the Leased Premises, or any additional improvements which Lessee may construct
thereon. If the annual premiums charged Lessor for such casualty insurance
exceed the standard premium rates because the nature of Lessee's operation
results in extra-hazardous exposure, then Lessee shall upon receipt of
appropriate premium invoices reimburse Lessor for any such increases covering in
such premiums.

(2) Lessee shall be responsible for providing, at Lessee's own expense, all
insurance coverage necessary for protection against loss or damage from fire,

hold Lessor harmless for such costs, expenses, claims, liability and damages
even if same arise or are alleged to arise in any manner from any negligent act
or omission of Lessor, or any act for which Lessor could be liable under
theories of strict or statutory liability, excepting only that arising from the
sole negligence of Lessor. In case of any action or proceeding brought against
Lessor by reason of such claim, Lessee, upon notice from Lessor, shall defend
such action or proceeding by counsel of Lessor's own choosing.

unless caused solely by Lessor's or Lessee's gross negligence, as the case may
be, except as may be herein otherwise expressly provided.

V.B      LESSOR'S LIEN FOR RENT

(1) Lessor shall have at all times, a valid security interest to secure payment
of all rentals and other sums of money due under this Lease from Lessee, and to
secure payment of any damages or loss that Lessor may suffer by reason of the
breach by Lessee of any covenant, agreement or condition contained in this
Lease, upon all goods, wares, equipment, fixtures, furniture, and other personal
property of Lessee which is now on the premises or which is placed on the
premises at some later date, and all proceeds from them. This property shall not
be removed from the premises without the consent of Lessor until all arrearages
in rent and all other sums of money then due to Lessor under this Lease have
been paid and discharged, and all the covenants, agreements, and conditions of
this Lease have been fully complied with and performed by Lessee. Upon


                                       10

<PAGE>   29
the occurrence of an event of* default by Lessee, Lessor may, in addition to any
other remedies provided in this Lease or by law, after giving reasonable notice
of the intent to take possession and giving an opportunity for a hearing on the
issue, enter upon the premises and take possession of any and all goods, wares,
equipment, fixtures, furniture, and other personal property of Lessee situated
on the premises without liability for trespass or conversion, and sell the same
at public or private sale, with or without having the property at the sale,
after giving Lessee reasonable notice of the time and place of any public sale
or of the time after which any private sale is to be made. Lessor or its assigns
may purchase any items to be sold at such a sale unless they are prohibited from
doing so by law. Unless otherwise provided by law, and without intending to
exclude any other manner of giving Lessee reasonable notice, the requirement of
reasonable notice shall be met if such notice is given at least twenty-one (21)
days before the time of the sale. The proceeds from any such dispositions, less
any and all expenses connected with the taking of possession, holding and
selling of the property (including reasonable attorney's fees and other
expenses), shall be applied as a credit against the indebtedness secured by the
security interest granted in this section. Any surplus shall be paid to Lessee
or as otherwise required by law; and Lessee shall pay any deficiencies
immediately. Upon request by Lessor, Lessee agrees to execute and deliver to
Lessor a financing statement in form sufficient to perfect the security interest
of Lessor in the aforementioned property and proceeds under the provisions of
the Uniform Commercial Code in force in the State of Texas. The statutory lien
for rent is not waived, the security interest granted in this article being in
additions and supplementary, to that lien.

V.C      ABANDONMENT

(1) In the event the Leased Premises are abandoned by Lessee, Lessor shall have
the right, but not the obligation, to relet same for the remainder of the term
provided for herein; and if the rent received through such reletting does not at
least equal the rent provided for herein, Lessee shall pay and satisfy any
deficiency between the amount of the rent so provided for and that received
through reletting, and, in addition thereto, shall pay all expenses incurred in
connection with any such reletting including but not limited to the cost of
restoring premises to its prior condition. Nothing herein shall be construed as
in any way denying Lessor the right in the event of abandonment of said premises
or other breach of this Agreement by Lessee, to treat the same as an entire
breach and at Lessor's option immediately sue for the entire breach of this
Agreement and any and all damages which Lessor suffers thereby.

V.D      HOLDING OVER

(1) In the event of holding over by Lessee after expiration of termination of
this lease, Lessee shall pay as liquidated damages double rent on a per diem
basis, for the entire

*    Upon the occurrence of an event of default by Lessee, Lessor shall not take
     possession of any government owned goods, wares, equipment, furniture, and
     other kinds of government property situated on the premises.

                                       11

<PAGE>   30
holdover period. No holding over by Lessee after the term of this lease, either
with or without consent and acquiescence of Lessor, shall operate to extend the
lease for a longer period than one (1) month; and any holding over with the
consent of Lessor in writing shall thereafter constitute this lease a lease from
month to month.

V.E      FIRE CLAUSE

(I) In the event of a fire in the Leased Premises, Lessee shall immediately give
notice thereof to Lessor, if the Leased Premises, through no fault or neglect of
Lessee, its agents, employees, invitees or visitors, shall be partially
destroyed by fire or other casualty so as to render the premises untenantable,
the rental herein shall cease thereafter until such time as the Leased Premises
are made tenantable by Lessor. In the event of the total destruction of the
Leased Premises without fault or neglect of Lessee, its agents, employees,
invitees or visitors, or if from such cause the same shall be so damaged that
Lessor shall decide not to rebuild, then all rent owed up to the time of such
destruction or termination shall be paid by Lessee and thenceforth this lease
shall cease and come to an end. If such damage is due to the fault or neglect of
Lessee, then all repairs shall be at Lessee's expense and there shall be no
abatement of rent. This obligation shall survive regardless of whether Lessor is
or is alleged to be concurrently negligent in connection with said damages.

V.F      ESTOPPEL CERTIFICATE

(1) The Lessee agrees, at any time and from time to time, upon not less than
fifteen (15) business days' prior notice from the Lessor, to execute,
acknowledge and deliver to the Lessor a statement in writing (1) certifying that
this Lease is unmodified and in full force and effect (or if there have been
modifications, that this Lease is in full force and effect as modified and
stating the modifications); (2) stating the dates to which the rent and other
charges hereunder have been paid by the Lessee; (3) stating whether or not the
Lessee has knowledge that the Lessor is in default in the performance of any
covenant, agreement or condition contained in this Lease, and, if the Lessee has
knowledge of such a default specifying each such default; and (4) stating the
address to which notices to the Lessee shall be sent. Prior to the commencement
of or during the term of this Lease the Lessor shall, if requested by the
Lessee, deliver an estoppel certificate, in the substance and form described
above, relative to the status of this Lease and/or any ground lease, underlying
lease and/or mortgage encumbering the building, parking facility or land.

V.G      ATTORNEY'S FEE

(1) In the event Lessee makes default in the performance of any of the terms,
covenants, agreements or conditions contained in this lease such as to create a
breach thereof, and Lessor places the enforcement of this lease, or any part
thereof, or the collection of any rent due, or to become due hereunder, or
recovery of the possession of the Leased Premises in the hands of an attorney,
or files suit upon the same, Lessee agrees to pay Lessor its reasonable
attorney's fees, court costs, expert witness fees, and other costs of collection
as may be reasonably incurred by Lessor.

V.H      ALTERATION

written agreements and may not be altered, changed or amended, except by an
instrument in writing, signed by both parties hereto.

This lease shall be binding upon and inure to the benefit of the heirs, personal

                               ARTICLE 2.00 RENT

2.01. BASE RENT. Lessee agrees to pay monthly as base rent during the term of
this Lease the sum of money set forth in section 1.04 of this Lease, which
amount shall be payable to Lessor at
<PAGE>   2
the address shown above. One monthly installment of rent shall be due and
payable on the date of execution of this Lease by Lessee for the first month's
rent and a like monthly installment shall be due and payable on or before the
first day of each calendar month succeeding the commencement date or completion
date during the term of this Lease; provided, if the commencement date or the
completion date should be a date other than the first day of a calendar month,
the monthly rental set forth above shall be prorated to the end of that calendar
month, and all succeeding installments of rent shall be payable on or before the
first day of each succeeding calendar month during the term of this Lease.
Lessee shall pay, as additional rent, all other sums due under this Lease.

2.02. OPERATING EXPENSES. In the event Lessor's operating expenses for the
building and/or project of which the leased premises are a part shall, in any
calendar year during the term of this Lease, exceed the sum of $1997 Base Year
Operating Expenses, including taxes and insurance per square foot, taxes, and
insurance. Lessee agrees to pay as additional rent lessee's pro rata share of
such excess operating expenses. Lessee occupies 17,920 square feet of space in a
project totaling 140,762 square feet (12.73%). Lessor may invoice Lessee monthly
for Lessee's pro rata share of the estimated operating expenses for each
calendar year, which amount shall be adjusted each year based upon anticipated
operating expenses. Within nine months following the close of each calendar
year, Lessor shall provide Lessee an accounting showing in reasonable detail all
computations of additional rent due under this section. In the event the
accounting shows that the total of the monthly payments made by Lessee exceeds
the amount of additional rent due by Lessee under this section, the accounting
shall be accompanied by a refund. In the event the accounting shows that the
total of the monthly payments made by Lessee is less than the amount of
additional rent due by Lessee under this section, the account shall be
accompanied by an invoice for the additional rent. Notwithstanding any other
provision in this Lease, during the year in which the Lease terminates, Lessor,
prior to the termination date, shall have the option to invoice Lessee for
Lessee's pro rata share of the excess operating expenses based upon the previous
year's operating expenses. If this Lease shall terminate on a day other than the
last day of a calendar year, the amount of any additional rent payable by Lessee
applicable to the year in which such termination shall occur shall be prorated
on the ratio that the number of days from the commencement of the calendar year
to and including the termination date bears to 365. Lessee shall have the right,
at its own expense and within a reasonable time, to audit Lessor's books
relevant to the additional rent payable under this section. Lessee agrees to pay
any additional rent due under this section within ten days following receipt of
the invoice or accounting showing additional rent due.

2.03. DEFINITION OF OPERATING EXPENSES. The term "operating expenses" includes
all expenses incurred by Lessor with respect to the maintenance and operation of
the building of which the leased premises are a part, including, but not limited
to, the following: maintenance, repair and replacement costs; security;
management fees, wages and benefits payable to employees of Lessor whose duties
are directly connected with the operation and maintenance of the building; all
services, utilities, supplies, repairs, replacements or other expenses for
maintaining and operating the common parking and plaza areas; the cost,
including interest, amortized over its useful life, of any capital improvement
made to the building by Lessor after the date of this Lease which is required
under any governmental law or regulation that was not applicable to the building
at the time it was constructed; the cost, including interest, amortized over its
useful life, of installation of any device or other equipment which improves the
operating efficiency of any


                                       2
<PAGE>   3
system within the leased premises and thereby reduces operating expenses; all
other expenses which would generally be regarded as operating and maintenance
expenses which would reasonably be amortized over a period not to exceed five
years; all real property taxes and installments of special assessments,
including dues and assessments by means of deed restrictions and/or owners'
associations which accrue against the building of which the leased premises are
a part during the term of this Lease; and all insurance premiums Lessor is
required to pay or deems necessary to pay, including public liability insurance,
with respect to the building. The term operating expenses does not include the
following: repairs, restoration or other work occasioned by fire, wind, the
elements or other casualty; income and franchise taxes of Lessor; expenses
incurred in leasing to or procuring of lessees, leasing commissions, advertising
expenses and expenses for the renovating of space for new lessees; interest or
principal payments on any mortgage or other indebtedness of Lessor; compensation
paid to any employee of Lessor above the grade of property manager, any
depreciation allowance or expense; or operating expenses which are the
responsibility of Lessee.

2.04. LATE PAYMENT CHARGE. Other remedies for nonpayment of rent withstanding,
if the monthly rental payment is not received by Lessor on or before the tenth
day of the month for which the rent is due, or if any other payment due Lessor
by Lessee is not received by Lessor on or before the tenth day of the month next
following the month in which Lessee was invoiced, a late payment charge of five
percent of such past due amount shall become due and payable in addition to such
amounts owed under this Lease.

2.05. INCREASE IN INSURANCE PREMIUMS. If an increase in any insurance premiums
paid by Lessor for the building is caused by Lessee's use of the leased premises
in a manner other than as set forth in section 1.06, or if Lessee vacates the
leased premises and causes an increase in such premiums, then Lessee shall pay
as additional rent the amount of such increase to Lessor.

2.06. SECURITY DEPOSIT. The security deposit set forth above shall be held by
Lessor for the performance of Lessee's covenants and obligations under this
Lease, it being expressly understood that the deposit shall not be considered an
advance payment of rental or a measure of Lessor's damage in case of default by
Lessee. Upon the occurrence of any event of default by Lessee or breach by
Lessee of Lessee's covenants under this Lease, Lessor may, from time to time,
without prejudice to any other remedy, use the security deposit to the extent
necessary to make good any arrears of rent, or to repair any damage or injury,
or pay any expense or liability incurred by Lessor as a result of the event of
default or breach of covenant, and any remaining balance of the security deposit
shall be returned by Lessor to Lessee upon termination of this Lease. If any
portion of the security deposit is so used or applied, Lessee shall upon ten
days written notice from Lessor, deposit with Lessor by cash or cashier's check
an amount sufficient to restore the security deposit to its original amount. The
security deposit shall transfer and be the responsibility of any new Owner or
transferee.

2.07. HOLDING OVER. In the event that the Lessee does not vacate the leased
premises upon the expiration or termination of this Lease, Lessee shall be a
tenant at will for the holdover period and all of the terms and provisions of
this Lease shall be applicable during that period, except that Lessee shall pay
Lessor as base rental for the period of such holdover an amount equal to one and
one-half times the base rent which would have been payable by Lessee had the
holdover period been a part of the original term of this Lease. Lessee agrees to
vacate and deliver the


                                       3
<PAGE>   4
leased premises to Lessor upon Lessee's receipt of notice from Lessor to vacate.
The rental payable during the holdover period shall be payable to Lessor on
demand. No holding over by Lessee, whether with or without the consent of
Lessor, shall operate to extend the term of this Lease.

                         ARTICLE 3.00 OCCUPANCY AND USE

3.01. USE. Lessee warrants and represents to Lessor that the leased premises
shall be used and occupied only for the purpose as set forth in section 1.06.
Lessee shall occupy the leased premises, conduct its business and control its
agents, employees, invitees and visitors in such a manner as is lawful,
reputable and will not create a nuisance. Lessee shall not permit any operation
which emits any odor or matter which intrudes into other portions of the
building, use any apparatus or machine which makes undue noise or causes
vibration in any portion of the building or otherwise interfere with, annoy or
disturb any other lessee in its normal business operations or Lessor in its
management of the building. Lessee shall neither permit any waste on the lease
premises nor allow the leased premises to be used in any way which would, in the
opinion of Lessor, be extra hazardous on account of fire or which would in any
way increase or render void the fire insurance on the building. Lessee warrants
to Lessor that the insurance questionnaire (filled out by Lessee, signed and
presented to Lessor prior to the execution of this Lease) accurately reflects
Lessee's original intended use of the leased premises. The insurance
questionnaire is made a part of this Lease by reference as though fully copied
herein. If at any time during the term of this Lease the State Board of
Insurance or other insurance authority disallows any of Lessor's sprinkler
credits or imposes any additional penalty or surcharge in Lessor's insurance
premiums because of Lessee's original or subsequent placement or use of storage
racks or bins, method of storage or nature of Lessee's inventory or any other
act of Lessee, Lessee agrees to pay as additional rent the increase (between
fire walls) in Lessor's insurance premiums.

3.02. SIGNS. No sign of any type or description shall be erected, placed or
painted in or about the leased premises or project except those signs submitted
to Lessor in writing and approved by Lessor in writing, and which signs are in
conformance with Lessor's sign criteria established for the project.

3.03. COMPLIANCE WITH LAWS, RULES AND REGULATIONS. Lessee, at Lessee's sole cost
and expense, shall comply with all laws, ordinance, orders, rules and
regulations of state, federal, municipal or other agencies or bodies having
jurisdiction over use, condition and occupancy of the leased premises. Lessee
will comply with the rules and regulations of the building adopted by Lessor
which are set forth on a schedule attached to this Lease. Lessor shall have the
right at all times to change and amend the rules and regulations in any
reasonable manner as may be deemed advisable for the safety, care, cleanliness,
preservation of good order and operation or use of the building or the lease
premises. All changes and amendments to the rules and regulations of the
building will be sent by Lessor to Lessee in writing and shall thereafter be
carried out and observed by Lessee.

3.04. WARRANTY OF POSSESSION. Lessor warrants that it has the right and
authority to execute this Lease, and Lessee, upon payment of the required rents
and subject to the terms, conditions, covenants and agreements contained in this
Lease, shall have possession of the leased premises


                                       4
<PAGE>   5
during the full term of this Lease as well as any extension or renewal thereof.
Lessor shall not be responsible for the acts or omissions of any other lessee or
third party that may interfere with Lessee's use and enjoyment of the leased
premises. In the event of sale or transfer of building, Tenant's lease shall not
be disturbed.

3.05. INSPECTION. Lessor or its authorized agents shall at any and all
reasonable times have the right to enter the leased premises with reasonable
notice to inspect the same, to supply janitorial service or any other service to
be provided by Lessor, to show the leased premises to prospective purchasers or
lessees, and to alter improve or repair the leased premises or any other portion
of the building. Lessee hereby waives any claim for damages for injury or
inconvenience to or interference with Lessee's business, any loss of occupancy
or use of the leased premises, and any other loss occasioned thereby. Lessor
shall at all times have and retain a key with which to unlock all of the doors
in, upon and about the leased premises. Lessee shall not change Lessor's lock
system or in any other manner prohibit Lessor from entering the leased premises.
Lessor shall have the right to use any and all means which Lessor may deem
proper to open any door in an emergency without liability therefor.

                       ARTICLE 4.00 UTILITIES AND SERVICE

4.01. BUILDING SERVICES. Lessor shall provide the normal utility serve
connections to the building. Lessee shall pay the cost of all utility services,
including, but not limited to, initial connection charges, all charges for gas,
electricity, water, sanitary and storm sewer service, and for all electric
lights. However, in a multi-occupancy building, Lessor may provide water to the
leased premises, in which case Lessee agrees to pay to Lessor its pro rata share
of the cost of such water. Lessee shall pay all costs caused by Lessee
introducing excessive pollutants or solids other than ordinary human waste into
the sanitary sewer system, including permits, fees and charges levied by any
governmental subdivision for any such pollutants or solids. Lessee shall be
responsible for the installation and maintenance of any dilution tanks, holding
tanks, settling tanks, sewer sampling devices, sand traps, grease traps or
similar devices as may be required by any governmental subdivision for Lessee's
use of the sanitary sewer system. If the leased premises are in a
multi-occupancy building, Lessee shall pay all surcharges levied due to Lessee's
use of sanitary sewer or waste removal services insofar as such surcharges
affect Lessor or other lessees in the building. Lessor shall not be required to
pay for any utility services, supplies or upkeep in connection with the leased
premises or building.

<PAGE>   6
liable to Lessee, except as expressly provided in this Lease, for any damage or
inconvenience; and Lessee shall not be entitled to any abatement or reduction of
rent by reason of any repairs, alterations or additions made by Lessor under
this Lease. Roof shall be free of any leakage upon Tenant's occupancy or a
reasonable time thereafter.

condition, including, but not limited to, heating, ventilating and air
conditioning systems, down spouts, fire sprinkler system, dock bumpers, lawn
maintenance, pest control and extermination, trash pick-up and removal, and
painting the building and exterior doors. Lessee shall repair and pay for any
damage caused by any act or omission of Lessee or Lessee's agents, employees,
invitees, licensees or visitors. If the leased premises are in a multi-occupancy
building or project, Lessor shall perform, on behalf of Lessee, lawn
maintenance, painting, and trash pick-up and removal; Lessee agrees to pay
Lessor, as additional rent, Lessee's pro rata share of the cost of such services
within ten days from receipt of lessor's invoice, or Lessor may by monthly
invoice direct Lessee to prepay the estimated costs for the current calendar
year, and such amount shall be adjusted annually. If the leased premises are
served by rail, Lessee agrees, if requested by the railroad, to enter into a
joint maintenance agreement with the railroad and bear its pro rata share of the
cost of maintaining the railroad ____. If Lessee fails to make the repairs or
replacements promptly as required herein, Lessor may, at its option, make the
repairs and replacements and the cost of such repairs and replacements shall be
charged to Lessee as additional rent and shall become due and payable by Lessee
within ten days from receipt of Lessor's invoice. Costs incurred under this
section are the total responsibility of Lessee and do not constitute operating
expense under section 2.02.

5.03. REQUEST FOR REPAIRS. All requests for repairs or maintenance that are the
responsibility of Lessor pursuant to any provision of this Lease must be made in
writing to Lessor at the address in section 1.05. If Landlord does not repair
within a reasonable time, Tenant shall make repairs and seek reimbursement from
Landlord or offset future rent due.

5.04. LESSEE DAMAGES. Lessee shall not allow any damage to be committed on any
portion of the leased premises or building, and at the termination of this
Lease, by lapse of time or otherwise, Lessee shall deliver the leased premises
to Lessor in as good condition as existed at the commencement date of this
Lease, ordinary wear and tear excepted. The cost and expense of any repairs
necessary to restore the condition of the leased premises shall be borne by
Lessee.

5.05. MAINTENANCE CONTRACT. Lessee shall, at its sole cost and expense, during
the term of this Lease maintain a regularly scheduled preventative maintenance
service contract with a maintenance contractor for the servicing of all hot
water, heating and air conditioning systems and equipment within the leased
premises. The maintenance contractor and contract must be approved by Lessor and
must include all services suggested by the equipment manufacturer.

                   ARTICLE 6.00 ALTERATIONS AND IMPROVEMENTS

6.01. LESSOR IMPROVEMENTS. If construction to the leased premises is to be
performed by Lessor prior to or during Lessee's occupancy, Lessor will complete
the construction of the improvements to the leased premises, in accordance with
plans and specifications agreed to by Lessor and Lessee, which plans and
specifications are made a part of this Lease by reference.


                                       6
<PAGE>   7
Lessee shall execute a copy of the plans and specifications and change orders,
if applicable, setting forth the amount of any costs to be borne by Lessee
within seven days of receipt of the plans and specifications. In the event
Lessee fails to execute the plans and specifications and change order within the
seven day period, Lessor may, at its sole option, declare this Lease cancelled
or notify Lessee that the base rent shall commence on the completion date even
though the improvements to be constructed by Lessor may not be complete. Any
changes or modifications to the approved plans and specifications shall be made
and accepted by written change order or agreement signed by Lessor and Lessee
and shall constitute an amendment to this Lease.

6.02. LESSEE IMPROVEMENTS. Lessee shall not make or allow to be made any
alterations or physical additions in or to the leased premises without first
obtaining the written consent of Lessor. Any alterations, physical additions or
improvements to the leased premises made by Lessee shall at once become the
property of Lessor and shall be surrendered to Lessor upon the termination of
this Lease; provided, however, Lessor, at its option, may require Lessee to
remove any physical additions and/or repair any alterations in order to restore
the leased premises to the condition existing at the time Lessee took
possession, all costs and removal and/or alterations to be borne by Lessee. This
clause shall not apply to moveable equipment or furniture owned by Lessee, which
may be removed by Lessee at the end of the term of this Lease if Lessee is not
then in default and if such equipment and furniture are not then subject to any
other rights, liens and interest of Lessor.

                      ARTICLE 7.00 CASUALTY AND INSURANCE

7.01. SUBSTANTIAL DESTRUCTION. If the leased premises should be totally
destroyed by fire or other casualty, or if the leased premises should be damaged
so that rebuilding cannot reasonably be completed within ninety working days
after the date of written notification by Lessee to Lessor of the destruction,
this Lease shall terminate and the rent shall be abated for the unexpired
portion of the Lease, effective as of the date of the written notification.

7.02. PARTIAL DESTRUCTION. If the leased premises should be partially damaged by
fire or other casualty, and rebuilding or repairs can reasonably be completed
within ninety working days from the date of written notification by Lessee to
Lessor of the destruction, this Lease shall not terminate, and Lessor shall at
its sole risk and expense proceed with reasonable diligence to rebuild or repair
the building or other improvements to substantially the same condition in which
they existed prior to the damage. If the leased premises are to be rebuilt or
repaired and are untenantable in whole or in part following the damage, and the
damage or destruction was not caused or contributed to by act or negligence of
Lessee, its agents, employees, invitees or those for whom Lessee is responsible,
the rent payable under this Lease during the period for which the leased
premises are untenantable shall be adjusted to such an extent, as may be fair
and reasonable under the circumstances. In the event that Lessor fails to
complete the necessary repairs or rebuilding within ninety working days from the
date of written notification by Lessee to Lessor of the destruction, Lessee may
at its option terminate this Lease by delivering written notice of termination
to Lessor, whereupon all rights and obligations under this Lease shall cease to
exist.


                                       7
<PAGE>   8
7.03. PROPERTY INSURANCE. Lessor shall at all times during the term of this
Lease maintain a policy or policies of insurance with the premiums paid in
advance, issued by and binding upon some solvent insurance company, insuring the
building against all risk of direct physical loss in an amount equal to at least
ninety percent of the full replacement cost of the building structure and its
improvements as of the date of the loss; provided, Lessor shall not be obligated
in any way or manner to insure any personal property (including, but not limited
to, any furniture, machinery, goods or supplies) of Lessee upon or within the
leased premises, any fixtures installed or paid for by Lessee upon or within the
leased premises, or any improvements which Lessee may construct on the leased
premises. Lessee shall have no right in or claim to the proceeds of any policy
of insurance maintained by Lessor even if the cost of such insurance is borne by
Lessee as set forth in article 2.00.

7.04. WAIVER OF SUBROGATION. Anything in this Lease to the contrary
notwithstanding, Lessor and Lessee hereby waives and release each other of and
from any and all right of recovery, claim, action or cause of action, against
each other, their agents, officers and employees, for any loss or damage that
may occur to the leased premises, improvements to the building of which the
leased premises are a part, or personal property within the building, by reason
of fire or the elements, regardless of cause or origin, including negligence of
Lessor or Lessee and their agents, officers and employees. Lessor and Lessee
agree immediately to give their respective insurance companies which have issued
policies of insurance covering all risk of direct physical loss, written notice
of the terms of the mutual waivers contained in this section, and to have the
insurance policies properly endorsed, if necessary, to prevent the invalidation
of the insurance coverages by reason of the mutual waivers.

7.05. HOLD HARMLESS. Lessor shall not be liable to Lessee's employees, agents,
invitees, licensees, or to any other person, for an injury to person or damage
to property on or about the leased premises caused by any act or omission of
Lessee, its agents, servants or employees, or of any other person entering upon
the leased premises under express or implied invitation by Lessee, or caused by
the improvements located on the leased premises becoming out of repair, the
failure or cessation of any service provided by Lessor (including security
service and devices), or caused by leakage of gas, oil, water or steam or by
electricity emanating from the leased premises. Lessee agrees to indemnify and
hold harmless Lessor of and from any loss, attorney's fees, expenses or claims
arising out of any such damage or injury.

                           ARTICLE 8.00 CONDEMNATION

8.01. SUBSTANTIAL TAKING. If all or a substantial part of the leased premises
are taken for any public or quasi-public use under any governmental law,
ordinance or regulation, or by right of eminent domain or by purchase in lieu
thereof, and the taking would prevent or materially interfere with the use of
the leased premises for the purpose for which it is then being used, this Lease
shall terminate and the rent shall be abated during the unexpired portion of
this Lease effective on the date physical possession is taken by the condemning
authority. Lessee shall have no claim to the condemnation award or proceeds in
lieu thereof.

8.02. PARTIAL TAKING. If a portion of the leased premises shall be taken for any
public or quasi-public use under any governmental law, ordinance or regulation,
or by right of eminent domain or by purchase in lieu thereof, and this Lease is
not terminated as provided in section 8.01 above,


                                       8
<PAGE>   9
Lessor shall at Lessor's sole risk and expense, restore and reconstruct the
building and other improvements on the leased premises to the extent necessary
to make it reasonably tenantable. The rent payable under this Lease during the
unexpired portion of the term shall be adjusted to such an extent as may be fair
and reasonable under the circumstances. Lessee shall have no claim to the
condemnation award or proceeds in lieu thereof.

                      ARTICLE 9.00 ASSIGNMENT OR SUBLEASE

9.01. LESSOR ASSIGNMENT. Lessor shall have the right to sell, transfer or
assign, in whole or in part, its rights and obligations under this Lease and in
the building. Any such sale, transfer or assignment shall operate to release
Lessor from any and all liabilities under this Lease arising after the date of
such sale, assignment or transfer, except Security Deposit shall be transferred
to the new party.

9.02. LESSEE ASSIGNMENT. Lessee shall not assign, in whole or in part, this
Lease, or allow it to be assigned, in whole or in part, by operation of law or
otherwise (including without limitation by transfer of a majority interest of
stock, merger, or dissolution, which transfer of majority interest of stock,
merger or dissolution shall be deemed an assignment) or mortgage or pledge the
same, or sublet the leased premises, in whole or in part, without the prior
written consent of Lessor, and in no event shall any such assignment or sublease
ever release Lessee or any guarantor from any obligation or liability hereunder.
No assignee or sublessee of the leased premises or any portion thereof may
assign or sublet the leased premises or any portion thereof. Landlord shall not
unreasonably withhold consent to Sublease.

9.03. CONDITIONS OF ASSIGNMENT. If Lessee desires to assign or sublet all or any
part of the leased premises to an outside third party, it shall so notify Lessor
at least thirty days in advance of the date on which Lessee desires to make such
assignment or sublease. Lessee shall provide Lessor with a copy of the proposed
assignment or sublease and such information as Lessor might request concerning
the proposed sublessee or assignee to allow Lessor to make informed judgments as
to the financial condition, reputation, operations and general desirability of
the proposed sublessee or assignee. Within fifteen days after Lessor's receipt
of Lessee's proposed assignment or sublease and all required information
concerning the proposed sublessee or assignee, Lessor shall have the following
options: (1) cancel this Lease as to the leased premises or portion thereof
proposed to be assigned or sublet; (2) consent to the proposed assignment or
sublease, and, if the rent due and payable by any assignee or sublessee under
any such permitted assignment or sublease (or a combination of the rent payable
under such assignment or sublease plus any bonus or any other consideration or
any payment incident thereto) exceeds the rent payable under this Lease for such
space, Lessee shall pay to Lessor all such excess rent and other excess
consideration within ten days following receipt thereof by Lessee; or (3)
refuse, with reasonable cause, to consent to the proposed assignment or
sublease, which refusal shall be deemed to have been exercised unless Lessor
gives Lessee written notice providing otherwise. Upon the occurrence of an event
of default, if all or any part of the leased premises are then assigned or
sublet, Lessor, in addition to any other remedies provided by this Lease or
provided by law, may, at its option, collect directly from the assignee or
sublessee all rents becoming due to Lessee by reason of the assignment or
sublease, and Lessor shall have a security interest in all properties on the
leased premises to secure payment of such sums. Any collection directly by


                                       9
<PAGE>   10
Lessor from the assignee or sublessee shall not be construed to constitute a
novation or a release of Lessee or any guarantor from the further performance of
its obligations under this Lease.

9.04. RIGHTS OF MORTGAGEE. Lessee accepts this Lease subject and subordinate to
any recorded mortgage or deed of trust lien presently existing or hereafter
created upon the building or project and to all existing recorded restrictions,
covenants, easements and agreements with respect to the building or project.
Lessor is hereby irrevocably vested with full power and authority to subordinate
Lessee's interest under this Lease to any first mortgage or deed of trust lien
hereafter placed on the leased premises, and Lessee agrees upon demand to
execute additional instruments subordinating this Lease as Lessor may require.
If the interest of Lessor under this Lease shall be transferred by reason of
foreclosure or other proceedings for enforcement of any first mortgage or deed
of trust on the leased premises, Lessee shall be bound to the transferee
(sometimes called the "Purchaser") at the option of the Purchaser, under the
terms, covenants and conditions of this Lease for the balance of the term
remaining, including any extensions or renewals, with the same force and effect
as if the Purchaser were Lessor under this Lease, and, if requested by the
Purchaser, Lessee agrees to attorn to the Purchaser, including the first
mortgagee under any such mortgage if it be the Purchaser, as its Lessor.

9.05. ESTOPPEL CERTIFICATES. Lessee agrees to furnish, from time to time, within
ten days after receipt of a request from Lessor or Lessor's mortgagee, a
statement certifying, if applicable, the following: Lessee is in possession of
the leased premises; the leased premises are acceptable; the Lease is in full
force and effect; the Lease is unmodified; Lessee claims no present charge,
lien, or claim of offset against rent; the rent is paid for the current month,
but is not prepaid for more than one month and will not be prepaid for more than
one month in advance; there is no existing default by reason of some act or
omission by Lessor; and such other matters as may be reasonably required by
Lessor or Lessor's mortgagee. Lessee's failure to deliver such statement, in
addition to being a default under this Lease, shall be deemed to establish
conclusively that this Lease is in full force and effect except as declared by
Lessor, that Lessor is not in default of any of its obligations under this
Lease, and that Lessor has not received more than one month's rent in advance.

                              ARTICLE 10.00 LIENS

10.01. LANDLORD'S LIEN. As security for payment of rent, damages and all other
payments required to be made by this Lease, Lessee hereby grants to Lessor a
lien upon all property of Lessee now or subsequently located upon the leased
premises. If Lessee abandons or vacates any substantial portion of the leased
premises or is in default in the payment of any rentals, damages or other
payments required to be made by this Lease or is in default of any other
provision of this Lease, Lessor may enter upon the leased premises, by picking
or changing locks if necessary, and take possession of all or any part of the
personal property, and may sell all or any part of the personal property at a
public or private sale, in one or successive sales, with or without notice, to
the highest bidder for cash, and, on behalf of Lessee, sell and convey all or
part of the personal property to the highest bidder, delivering to the highest
bidder all of Lessee's title and interest in the personal property sold. The
proceeds of the sale of the personal property shall be applied by Lessor toward
the reasonable costs and expenses of the sale, including attorney's fees, and
then toward the payment of all sums then due by Lessee to Lessor under the terms
of


                                       10
<PAGE>   11
this Lease. Any excess remaining shall be paid to Lessee or any other person
entitled thereto by law.

10.02. UNIFORM COMMERCIAL CODE. This Lease is intended as and constitutes a
security agreement within the meaning of the Uniform Commercial Code of the
state in which the leased premises are situated. Lessor, in addition to the
rights prescribed in this Lease, shall have all of the rights, titles, liens and
interests in and to Lessee's property, now or hereafter located upon the leased
premises, which may be granted a secured party, as that term is defined, under
the Uniform Commercial Code to secure to Lessor payment of all sums due and the
full performance of all Lessee's covenants under this Lease. Lessee will on
request execute and deliver to Lessor a financing statement for the purpose of
perfecting Lessor's security interest under this Lease or Lessor may file this
Lease or a copy thereof as a financing statement. Unless otherwise provided by
law and for the purpose of exercising any right pursuant to this section, Lessor
and Lessee agree that reasonable notice shall be met if such notice is given by
ten days written notice, certified mail, return receipt requested, to Lessor or
Lessee at the addresses specified herein.

10.03. LANDLORD'S LIEN. Landlord's lien shall subordinate to Tenant's first
lienholders and shall not apply to contents owned by outside parties.

                       ARTICLE 11.00 DEFAULT AND REMEDIES

11.01. DEFAULT BY LESSEE. The following shall be deemed to be events of default
by Lessee under this Lease: (1) Lessee shall fail to pay when due any
installment of rent or any other payment required pursuant to this Lease; (2)
Lessee shall abandon any substantial portion of the leased premises; (3) Lessee
shall fail to comply with any term, provision or covenant of this Lease, other
than the payment of rent, and the failure is not cured within ten days after
written notice to Lessee; (4) Lessee shall file a petition or be adjudged
bankrupt or insolvent under any applicable federal or state bankruptcy or
insolvency law or admit that it cannot meet its financial obligations as they
become due; or a receiver or trustee shall be appointed for all or substantially
all of the assets of Lessee; or Lessee shall make a transfer in fraud of
creditors or shall make an assignment for the benefit of creditors; or (5)
Lessee shall do or permit to be done any act which results in a lien being filed
against the leased premises or the building and/or project of which the leased
premises are a part.

11.02. REMEDIES FOR LESSEE'S DEFAULT. Upon the occurrence of any event of
default set forth in this Lease, Lessor shall have the option to pursue any one
or more of the remedies set forth herein without any notice or demand. (1)
Lessor may enter upon and take possession of the leased premises, by picking or
changing locks if necessary, and lock out, expel or remove Lessee and any other
person who may be occupying all or any part of the leased premises without being
liable for any claim for damages, and relet the leased premises on behalf of
Lessee and receive the rent directly by reason of the reletting. Lessee agrees
to pay Lessor on demand any deficiency that may arise by reason of any reletting
of the leased premises; further, Lessee agrees to reimburse Lessor for any
expenditures made by it in order to relet the leased premises, including, but
not limited to, remodeling and repair costs. (2) Lessor may enter upon the
leased premises, by picking or changing locks if necessary, without being liable
for any claim for damages, and do whatever Lessee is obligated to do under the
terms of this Lease. Lessee agrees to reimburse Lessor on demand for any
expenses which Lessor may incur in effecting


                                       11
<PAGE>   12
compliance with Lessee's obligations under this Lease; further, Lessee agrees
that Lessor shall not be liable for any damages resulting to Lessee from
effecting compliance with Lessee's obligations under this Lease caused by the
negligence of Lessor or otherwise. (3) Lessor may terminate this Lease, in which
event Lessee shall immediately surrender the leased premises to Lessor, and if
Lessee fails to surrender the leased premises, Lessor may, without prejudice to
any other remedy which it may have for possession or arrearages in rent, enter
upon and take possession of the leased premises, by picking or changing locks if
necessary, and lock out, expel or remove Lessee and any other person who may be
occupying all or any part of the lease premises without being liable for any
claim for damages. Lessee agrees to pay on demand the amount of all loss and
damage which Lessor may suffer by reason of the termination of this Lease under
this section, whether through inability to relet the leased premises on
satisfactory terms or otherwise. Notwithstanding any other remedy set forth in
this Lease, in the event Lessor has made rent concessions of any type or
character, or waived any base rent, and Lessee fails to take possession of the
leased premises on the commencement or completion date or otherwise defaults at
any time during the term of this Lease, the rent concessions, including any
waived base rent, shall be cancelled and the amount of the base rent or other
rent concessions shall be due and payable immediately as if no rent concessions
or waiver of any base rent had ever been granted. A rent concession or waiver of
the base rent shall not relieve Lessee of any obligation to pay any other charge
due and payable under this Lease including without limitation any sum due under
section 2.02. Notwithstanding anything contained in this Lease to the contrary,
this Lease may be terminated by Lessor only by mailing or delivering written
notice of such termination to Lessee, and no other act or omission of Lessor
shall be construed as a termination of this Lease.

                           ARTICLE 12.00 DEFINITIONS

12.01. ABANDON. "Abandon" means the vacating of all or a substantial portion of
the leased premises by Lessee, whether or not Lessee is in default of the rental
payments due under this Lease.

12.02. ACT OF GOD OR FORCE MAJEURE. An "act of God" or "force majeure" is
defined for purposes of this Lease as strikes, lockouts, sit downs, material or
labor restrictions by any governmental authority, unusual transportation delays,
riots, floods, washouts, explosions, earthquakes, fire, storms, weather
(including wet grounds or inclement weather which prevents construction), acts
of the public enemy, wars, insurrections and any other cause not reasonably
within the control of Lessor and which by the exercise of due diligence Lessor
is unable, wholly or in part, to prevent or overcome.

12.03. BUILDING OR PROJECT. "Building" or "project" as used in this Lease means
the building and/or project described in section 1.02, including the leased
premises and the land upon which the building or project is situated.

12.04. COMMENCEMENT DATE. "Commencement date" shall be the date set forth in
section 1.03. The commencement date shall constitute the commencement of the
term of this Lease for all purposes, whether or not Lessee has actually taken
possession.


                                       12
<PAGE>   13
12.05. COMPLETION DATE. "Completion Date" shall be the date on which the
improvements erected and to be erected upon the leased premises shall have been
completed in accordance with the plans and specifications described in article
6.00. The completion date shall constitute the commencement of the term of this
Lease for all purposes, whether or not Lessee has actually taken possession.
Lessor shall use its best efforts to establish the completion date as the date
set forth in section 1.03. In the event that the improvements have not in fact
been completed as of that date, Lessee shall notify Lessor in writing of its
objections. Lessor shall have a reasonable time after delivery of the notice in
which to take such corrective action as may be necessary and shall notify Lessee
in writing as soon as it deems such corrective action has been completed and the
improvements are ready for occupancy. Upon completion of construction, Lessee
shall deliver to Lessor a letter accepting the leased premises as suitable for
the purposes for which they are let and the date of such letter shall constitute
the commencement of the term of this Lease. Whether or not Lessee has executed
such letter of acceptance, taking possession of the leased premises by Lessee
shall be deemed to establish conclusively that the improvements have been
completed in accordance with the plans and specifications, are suitable for the
purposes for which the leased premises are let, and that the leased premises are
in good and satisfactory condition as of the date possession was so taken by
Lessee, except for latent defects, if any.

13.01. WAIVER. Failure of Lessor to declare an event of default immediately upon
its occurrence, or delay in taking any action in connection with an event of
default, shall not constitute a waiver of the default, but Lessor shall have the
right to declare the default at any time and take such action as is lawful or
authorized under this Lease. Pursuit of any one or more of the remedies set
forth in article 11.00 above shall not preclude pursuit of any one or more of
the other remedies provided elsewhere in this Lease or provided by law, nor
shall pursuit of any remedy constitute forfeiture or waiver of any rent or
damages accruing to Lessor by reason of the violation of any of the terms,
provisions or covenants of this Lease. Failure by Lessor to enforce one or more
of the remedies provided upon an event of default shall not be deemed or
construed to constitute a waiver of the default or of any other violation or
breach of any of the terms, provisions and covenants contained in this Lease.

13.02. ACT OF GOD. Lessor shall not be required to perform any covenant or
obligation in this Lease, or be liable in damages to Lessee, so long as the
performance or non-performance of the covenant of obligation is delayed, caused
or prevented by an act of God, force majeure or by Lessee.

13.03. ATTORNEY'S FEES. In the event Lessee defaults in the performance of any
of the terms, covenants, agreements or conditions contained in this Lease and
Lessor places in the hands of an attorney the enforcement of all or any part of
this Lease, the collection of any rent due or to become due or recovery of the
possession of the lease premises, Lessee agrees to pay Lessor's costs of
collection, including reasonable attorney's fees for the services of the
attorney, whether suit is actually filed or not.

<PAGE>   14
13.04. SUCCESSORS. This Lease shall be binding upon and inure to the benefit of
Lessor and Lessee and their respective heirs, personal representatives,
successors and assigns. It is hereby convenanted and agreed that should Lessor's
interest in the leased premises cease to exist for any reason during the term of
this Lease, then notwithstanding the happening of such event this Lease
nevertheless shall remain unimpaired and in full force and effect, and Lessee
hereunder agrees to attorn to the then owner of the leased premises.

13.05. RENT TAX. If applicable in the jurisdiction where the leased premises are
situated, Lessee shall pay and be liable for all rental, sales and use taxes or

                                  DEED OF LEASE

         THIS DEED OF LEASE (the "Lease") made as of December 16, 1998, between
WASHINGTON DESIGN CENTER L.L.C., a Delaware limited liability company
("Landlord"), and SPACEHAB, INCORPORATED, a Washington corporation ("Tenant").

         In consideration of the mutual promises set forth below, the parties
agree as follows:

                                   ARTICLE I

                           PREMISES; LANDLORD'S RIGHTS

         1.01 Premises. Subject to the terms and conditions hereof, Landlord
hereby leases to Tenant and Tenant hereby leases from Landlord Suite 814,
containing approximately 15,499 rentable square feet as indicated on the floor
plan attached hereto as Exhibit A- 1 (the "Premises"), of the building
constructed on the land identified in the legal description attached hereto as
Exhibit A-2 (the "Land"), known by street address as 300 D Street, S.W.,
Washington, D.C. (the "Building"). The "Property" consists of the Land and the
Building, together with all present and future easements, additions, expansions,
improvements and other rights appurtenant thereto. In addition to the exclusive
right to use and occupy the Premises subject to the terms hereof, Tenant shall,
subject to the terms hereof, have nonexclusive access to such portions of the
Property which are designated by Landlord as common areas and which are
reasonably required for the access to and use of the Premises (e.g., main lobby
entrances, common elevators, and the corridors, elevator lobby and restrooms on
the floor on which the Premises is located). Tenant shall have no other rights
to any portion of the Property other than as expressly set forth herein.
Landlord and Tenant agree that the rentable area of the Premises set forth above
shall be conclusive for all purposes of this Lease.

         1.02 Landlord's Rights. Landlord retains the exclusive right to use or
modify in any manner whatsoever all Property other than the Premises located
outside of the interior walls, ceiling and floor of the Premises, Building
systems, and structural parts of the Building. For example, Landlord may: (1)
change the name or the street address of the Building, (2) install or replace
any signs located outside the Premises; (3) regulate window treatments, fighting
fixtures and similar items visible from the common areas or exterior of the
Building; (4) regulate the finishing of services [including utilities and
telephone (but not including the telephone equipment within Tenant's Premises or
the servicer used by Tenant provided that such servicer shall have no right to
install equipment or fines of any type in the Building except within the
Premises) at commercially reasonable rates] to the Building or any occupant
thereof, (5) grant any person the exclusive right to conduct any business or
render any service in the Building, provided that such exclusive right shall not
operate to exclude Tenant from any use expressly permitted herein; and (6)
regulate the movement of individuals and property into and throughout the
Building outside the Premises, provided that the exercise of such rights does
not unreasonably limit access to the Premises or Tenant's right to conduct its
business and operate the Premises in its discretion (subject to the other terms
of this Lease). Landlord also retains the right to demolish that portion of the
Building which does not contain the Premises and to erect new improvements on
the Land, so long as such demolition and construction does not interfere with
and interrupt Tenant's use of the Premises; provided that, Landlord shall not
demolish the restrooms on the floor on which the Premises are located, the
existing means of access to the Premises, or any systems


                                       1
<PAGE>   6
which provide HVAC, electricity, plumbing or other services to the Premises,
unless Landlord makes arrangements for substitute facilities or services for the
same.

         1.03 Roof-Top Rights. Provided Tenant first executes and delivers to
Landlord the License Agreement attached hereto as Exhibit I, Tenant shall have
the right to utilize a portion of the roof of the Building for purposes of
installing and operating one or more satellite dishes or antennas, subject to
and in accordance with the terms of said Exhibit I.

                                   ARTICLE II

                             TERM; COMMENCEMENT DATE

         2.01 Term. The initial term of this Lease (the "Initial Term") shall
commence upon the date of this Lease (the "Commencement Date") and shall end at
11:59 p.m. on the day preceding the ninth (9th) anniversary of the Rent
Commencement Date as defined herein or any earlier date on which this Lease is
terminated (the "Expiration Date"). The Initial Term, together with the Renewal
Term (if any), is referred to herein as the "Term."

         2.02 Commencement Date. Landlord shall deliver all available portions
of the Premises to Tenant upon the execution hereof, and shall use reasonable
efforts to deliver the remainder of the Premises on or before January 20, 1998.
If Landlord fails to tender possession of the entire Premises to Tenant by
January 20, 1998, Landlord shall not be subject to liability, nor shall this
Lease be void or voidable in whole or in part, but in such event the Tenant
shall be entitled to one (1) additional day of rent abatement with regard to the
Premises for each day of delay in the tender of the Premises or any portion
thereof not tendered by January 20, 1998 which is not due to the acts or
omissions of Tenant or Tenant's agents, employees or contractors. The Premises
shall be provided to tenant in an "as is" condition pursuant to Section 7.01.
Upon delivery of the remainder of the Premises, Tenant shall execute and deliver
to Landlord a Declarations to Date of Delivery and Acceptance of Premises,
substantially in the form of Exhibit C attached hereto, confirming the
Commencement Date and delivery of the entire Premises.

         2.03 Commencement of Work. Tenant shall be permitted, subject to the
terms hereof, to commence construction of the Tenant Work (as herein defined)
and installation of telephones, computers, fixtures, furniture, etc., in the
Premises upon delivery thereof.

         2.04 Tenant Allowance. Landlord will provide Tenant with and allowance
(the "Tenant Allowance") of up to Three Hundred Nine Thousand Nine Hundred
Eighty Dollars ($309,980.00) for any construction, architectural, design, MEP
and cabling costs incurred in connection with the Tenant Work, Landlord will
reimburse Tenant for such costs incurred by the Tenant (not to exceed the amount
of the Tenant Allowance) upon completion of Tenant Work and Tenant providing
Landlord copies of paid bills supporting the amount of Tenant Allowance
requested and appropriate lien waiver and releases of liens. After final
completion of the Tenant Work and full payment of all costs incurred in
connection therewith, if directed by Tenant any unused Tenant Allowance shall be
applied to Tenant's rent obligations under this Lease next due after Tenant
provides written notice to Landlord to so apply the Tenant Allowance or
remaining portion thereof.

         2.05 Renewal Option. Subject to the terms and conditions hereof, Tenant
is hereby granted one (1) option (the "Renewal Option") to extend the Term for
an additional period of five (5) years (the "Renewal Term"), to commence at the
expiration of the Initial Term provided Tenant notifies


                                       2
<PAGE>   7
Landlord in writing of its intent to exercise the Renewal Option a minimum of
nine (9) months prior to the Expiration Date, and further provided that if
Tenant is in default on the date of giving such notice, said notice shall be
totally ineffective, or if Tenant is in default beyond the applicable notice and
cure period(s) (if any) pursuant to Section 18.02 on the last day of the Initial
Term at Landlord's option the Renewal Term shall not commence and this Lease
shall terminate at the end of the Initial Term. It is mutually agreed that all
provisions of the Lease, unless otherwise provided, will remain in full force
and effect for the Renewal Term (including the pass through of increases in
Operating Expenses and Real Estate Taxes which shall continue uninterrupted) and
further provided that Base Rent shall be the prevailing fair rental value of the
Premises as determined in accordance with this Section 2.05 at the time the
Renewal Term is to commence. Landlord shall notify Tenant of its determination
of fair rental value within thirty (30) days after Tenant exercises its Renewal
Option. If Tenant does not agree with Landlord's determination of fair rental
value, Tenant shall advise Landlord and each party shall designate in writing,
within ten (10) days after the expiration of the aforementioned thirty (30) day
period, an MAI or similarly accredited appraiser having at least 10 years
experience in the appraisal of commercial real estate in the Metropolitan
Washington, D.C. area, for the purpose of determining fair rental value. The
appraiser may not be affiliated in any respect with either Landlord or Tenant or
their respective affiliates. Within fifteen (15) days after the designation of
the appraisers, the two appraisers so designated shall designate a third
appraiser of the same qualifications. The appraisers so designated, shall within
forty-five (45) days after the date the third appraiser is designated, determine
the fair rental value of the Premises, taking into consideration all relevant
factors (including, but not limited to, that the Tax Base Year and the Operating
Expense Base Year are not being updated). If the three appraisers are unable to
agree upon the fair rental value, then the fair rental value of the Premises
shall be the average of the two closest appraisals.

                                  ARTICLE III

                             USE; LEGAL REQUIREMENTS

         3.01 Use. The Premises shall be used solely for general office purposes
and not in violation of any Legal Requirements (as defined in Section 3.02
hereof. Tenant shall not carry on or permit any activities which might: (1)
invalidate or increase the costs of any insurance coverages carried with respect
to the Building; (2) involve the storage, use or disposal of medical or
hazardous wastes or substances or the creation of an environmental hazard; or
(3) impair or interfere with (i) the structure of the Building or the operation
of Building systems, (ii) the character, reputation or appearance of the
Building as a first-class office building, (iii) the furnishing of services
(including utilities and telephone) to any portion of the Building or (iv) the
enjoyment by other occupants of the Building of the benefits of such occupancy
(for example, free of noise, odors or vibration emanating from the Premises).
The Premises shall not be used for the purposes of so-called "office suites,"
schools, governmental agencies, employment agencies, medical treatment
facilities, or any commercial or retail activities (other than general office
purposes as set forth above). Tenant shall at no expense to Landlord comply with
all Legal Requirements imposing any duty on Tenant or, to the extent
responsibility for the action required by such Legal Requirement is allocated to
Tenant hereunder with respect to the Premises and the use or occupation thereof
by Tenant.

         3.02 Legal Requirements. "Legal Requirements" means: (1) all laws,
statutes, ordinances, rules, regulations, directives and orders of federal
state, county or municipal authorities, whether now or hereafter in effect which
may be applicable to any portion of the Property, the use or operation thereof
or any interest therein; and (2) all requirements, obligations and conditions of
all instruments of record (as described on Exhibit K attached hereto and made a
part hereof) pertaining to any portion of


                                       3
<PAGE>   8
the Property, the use or operation thereof or any interest therein, now or
hereafter of record; provided that "Legal Requirements" shall exclude any
affirmative obligations imposed by any instrument placed of record after the
date hereof which exceed the Tenant's obligations hereunder or which conflict
with Tenant's rights hereunder.

                                   ARTICLE IV

                           BASE RENT; ADDITIONAL RENT

         4.01 Rent Generally. Each reference herein to "rent" shall unless
otherwise specified, mean the aggregate amount of "Base Rent" and "additional
rent" payable at any time or from time to time hereunder. Each item of rent
shall accrue continuously from the Rent Commencement Date until the Expiration
Date, and Tenant's obligation to pay the same shall survive termination of
Tenant's right of possession to the Premises and the end of the Term.

         4.02 Base Rent.

                  (a) From December 28, 1998 (the "Rent Commencement Date") and
during each of the Lease Years (as defined below), the "Base Rent" shall be Four
Hundred Sixty-eight Thousand Eight Hundred Forty-four and 75/100 Dollars
($468,844.75) annually (the annual Base Rent being the product of 15,499
rentable square feet times $30.25 per rentable square foot), payable by Tenant,
without demand therefor, in advance on the first day of each calendar month in
equal installments of Thirty-nine Thousand Seventy and 40/100 Dollars
($39,070.40); provided that the first installment of Base Rent shall be due upon
the execution of this Lease. Commencing on the first day of the sixth Lease
Year, Base Rent shall increase by $1.00 per square foot above the then escalated
amount of Base Rent. Notwithstanding the provisions of this subparagraph (a)
provided Tenant is not in default hereunder, Base Rent shall abate for the
ninety (90) day period commencing on the Rent Commencement Date.

                  (b) Commencing with the first day of the second Lease Year (as
defined below) and the first day of each Lease Year thereafter, with the
exception of the sixth Lease Year, Base Rent shall increase by an amount equal
to 2% of the Base Rent payable for the immediately preceding Lease Year, said
increase to be payable in equal monthly installments as aforesaid. The Base Rent
as so adjusted shall be the new Base Rent.

                  (c) "Lease Year" shall mean the twelve-month period beginning
on the first day of a calendar month occurring on or immediately after the Rent
Commencement Date, and each twelve-month period thereafter beginning on the
anniversary of such first day. If the Commencement Date is other than the first
day of a calendar month or this Lease terminates other than on the last day of a
calendar month, the Base Rent for each such partial calendar month shall be
prorated on the basis of 1/365 of the then current annual Base Rent.

         4.03 Additional Rent. All amounts, other than the Base Rent, payable by
Tenant hereunder or under any other agreement between Landlord and Tenant
relating to the Premises or Tenant's use or occupancy thereof shall be deemed to
be "additional rent." Each item of additional rent shall be payable immediately
upon Landlord's demand, unless otherwise expressly provided for herein.
Landlord's failure to make demand upon Tenant during the Term for any item of
additional rent (including rent adjustments provided for in Article V hereof)
shall not operate as a waiver of Landlord's right to demand or Tenant's
obligation to pay such additional rent, so long as Landlord makes such demand


                                       4
<PAGE>   9
within two (2) years after the date such amounts were originally due in
accordance with the terms hereof The determination of any item of additional
rent shall result in no decrease in the Base Rent. Whenever an item of
additional rent is to be determined based upon the amount of Base Rent, such
amount shall be determined pursuant to Section 4.02 hereof with no reduction for
credits, abatements or concessions.

         4.04 Rent Payments; No Waiver. Tenant shall pay all rents in lawful
money of the United States by good check (subject to collection) drawn to
Landlord's order on a national bank, and delivered to Landlord, c/o Merchandise
Mart Properties, Inc., 222 Merchandise Mart Plaza, Room 470, Chicago, Illinois
60654. Landlord's acceptance of rent with the knowledge of an existing default
hereunder shall not constitute a waiver thereof. Each rent payment shall be on
account of rents longest past due, and Landlord's acceptance of less than the
full amount of rent then due shall not constitute a waiver of any unpaid rent.
No writing accompanying any check or payment of rent shall constitute an accord
and satisfaction and Landlord may accept and endorse such check or payment
without limiting Landlord's right to recover the balance of such rent or pursue
any other remedy hereunder.

         4.05 Moratorium. If by virtue of any Legal Requirement the amount of
rent which Landlord may collect hereunder is limited, Tenant shall remain liable
for all rent provided for hereunder and such rent shall continue to accrue. When
such limitation is no longer in effect, Tenant shall promptly pay all accrued
and unpaid rent upon Landlord's demand, so long as Landlord makes such demand
within two (2) years after the date such amounts were originally due in
accordance with the terms hereof

         4.06 No Conditions. Tenant's covenant to pay rent is independent of all
other covenants and conditions, except for Landlord's covenant of quiet
enjoyment set forth in Section 13.01. Notwithstanding any other provision hereof
Tenant shall pay in full each item of rent when due without any demand (unless
expressly provided for herein), deduction or set-off, except with respect to
unused Tenant Allowance pursuant to Section 2.04 above and regardless of any
counterclaim.

                                   ARTICLE V

                                RENT ADJUSTMENTS

         5.01 Real Estate Taxes.

                  (a) In addition to the Base Rent, Tenant shall, in monthly
installments pursuant to Section 5.04 hereof pay to Landlord as additional rent
an amount (the "Tax Adjustment") equal to four and one tenth percent (4.1%),
subject to adjustment as provided for below ("Tenant's Share of Real Estate Tax
Increases"), of the amount by which Real Estate Taxes (as defined below) for the
then current Tax Year exceed Real Estate Taxes for the Tax Base Year. "Tax Year"
shall mean the 12-month, District of Columbia tax year commencing each October 1
and ending the following September 30. "Tax Base Year" shall mean the Tax Year
commencing October 1, 1998 and ending September 30, 1999. If the Tax Year
changes and the effect of the change can be reasonably determined, Landlord may
adjust Real Estate Taxes for the Tax Base Year to produce Tax Adjustments
substantially equivalent to those which would have been calculated without a
change in the Tax Year. Real Estate Taxes shall be calculated for each Tax Year,
including the Tax Base Year as if the building was at least 95% occupied.

                  (b) "Real Estate Taxes" shall mean all taxes, rates and
assessments, general and special foreseen or unforeseen of every kind and nature
which Landlord shall pay or become obligated


                                       5
<PAGE>   10
to pay because of or in any way connected with the ownership, leasing or
operation of the Property, including general real estate taxes, assessments,
impositions and governmental charges (including vault fees and transit or other
special district assessments) levied on or charged against the real estate or
personal property used in connection with the operation of the Property, or on
the right or privilege of leasing real estate or on the rentals or other
receipts from the Property (or on the value of the leases thereon), or on the
value of improvements made to the Property at any time for any purpose, or in
any way attributable to the ownership, leasing or operation of the Property.
Real Estate Taxes shall include all reassessments in connection with the sale or
lease of any portion of the Property, and all fees, costs and expenses
(including reasonable attorneys' fees and expenses) that Landlord incurs
contesting or attempting to reduce or limit Real Estate Taxes. The amount of any
tax refunds shall be applied as a credit to Real Estate Taxes for the relevant
Tax Year. If a refund is applicable to the Tax Base Year, Real Estate Taxes for
the Tax Base Year shall be reduced thereby, and Tax Adjustments shall be
recalculated. If the system of real estate taxation is changed or any new tax or
assessment is imposed or levied on the Property in lieu of any item of Real
Estate Taxes presently imposed or levied on real estate or fixtures in the
District of Columbia, Real Estate Taxes shall include the new tax, assessment
and levy. Real Estate Taxes shall not include any net income, inheritance or
estate taxes.

         5.02 Operating Expenses.

                  (a) In addition to the Base Rent, Tenant shall, in monthly
installments pursuant to Section 5.04 hereof pay to Landlord as additional rent
an amount (the "Operating Expense Adjustment") equal to four and one tenth
percent (4.1%) ("Tenant's Share of Operating Expense Increases") of the amount
by which Operating Expenses (as defined below) for the then current calendar
year exceed Operating Expenses for the calendar year commencing the January 1,
1999 (the "Operating Expense Base Year"). Operating Expenses shall be calculated
for each calendar year as if the Building was not less than 95% occupied.

                  (b) "Operating Expenses" shall mean all expenses, costs and
disbursements of every kind and nature paid, incurred, or otherwise arising
because of or in any way connected with the management, maintenance, servicing
repair and/or operation of the Property (including the costs of electrical
service, HVAC, cleaning, employee salaries, withholding and other taxes and
employee benefits, water and sewerage, landscaping, maintenance and service
contracts, security systems, management fees (not to exceed four percent)
equipment rental and all other usual and customary costs of operating and
maintaining a first-class office building in downtown Washington, D.C.).
Operating Expenses shall not include: (1) interest payments; (2) ground rental;
(3) depreciation; or (4) capital expenditures other than (i) those capital
expenditures incurred to reduce Operating Expenses and (ii) those capital
expenditures incurred to comply with any Legal Requirement to the extent such
compliance is not required as of the date hereof Landlord agrees to amortize the
cost of any capital expenditure (together with interest thereon at nine percent)
over the shorter of (i) the useful life thereof as determined under generally
accepted accounting principles, or (ii) the depreciation period permitted by the
Internal Revenue Code and only the portion of such amortization allocable to
each year shall be included in Operating Expenses for such year.

         5.03 Payments of Rent Adjustments. Commencing on the first day of the
month immediately following a notice from Landlord setting forth the then
cur-rent estimated Tax Adjustment and/or Operating Expense Adjustment
(collectively, "Rent Adjustments"), as estimated by Landlord from time to time,
Tenant shall pay monthly installments on account of Rent Adjustments. The amount
of each such installment shall equal the aggregate unpaid balance of the then
current estimated Rent Adjustments, divided by the number of months remaining in
the Lease Year. If upon the final determination of Rent Adjustments for each
Lease Year, the total installments paid on account of Rent


                                       6
<PAGE>   11
Adjustments do not equal the total actual amount of Rent Adjustments, Tenant
shall pay any balance due within thirty (30) days after receiving Landlord's
demand therefor, or, if applicable, Landlord shall credit against the next
payment of Base Rent due hereunder the amount of any overpayment.

         5.04 Audit Rights by Tenant. If Tenant disputes any Operating Expenses
or Real Estate Taxes statement, Tenant must provide Landlord with specific
written objections within 30 days after receiving the statement (failing which,
the statement will be deemed conclusive). Within 30 days after receiving these
objections, Landlord will either adjust the disputed statement in response to
Tenant's objection(s) and credit any overpayment to Tenant as stated above, or
notify Tenant that it believes Tenant's objection is without merit. If Tenant
timely disputes a statement and Landlord notifies Tenant that Tenant's objection
is without merit, Tenant may -- if Tenant is not then in default beyond any
applicable cure period -- cause a nationally recognized independent, certified
public accountant ("CPA") to audit the supporting data for the disputed
statement. However, Tenant may not exercise its audit right unless the audit
commences within 20 days after Landlord notifies Tenant that Tenant's objection
is without merit, nor may Tenant audit any statement more than once. The CPA
must sign a confidentiality statement in form acceptable to Landlord. Each audit
under this Section 5.04 must be conducted at Landlord's property manager's
District of Columbia office. If Landlord does not agree with the audit results
of the CPA Tenant selects, Landlord and Tenant will endeavor to resolve their
differences (failing which, the dispute will be conclusively determined based on
an independent audit by a third-party CPA selected by the parties or, failing
agreement, appointed by the American Arbitration Association or any recognized
successor thereto upon application by either party). The parties will make any
necessary adjustments in accordance with the third-party CPA audit. Tenant must
pay all costs and expenses of Tenant's audit (including, but not limited to,
reasonable copying charges). In addition, Tenant must pay the costs incurred in
connection with the third-party CPA audit (including, but not limited to,
reasonable copying charges) unless the amounts paid by Tenant to Landlord for
the year in question exceeded the amounts to which Landlord was entitled by more
than 5%, in which event Landlord will pay the costs incurred in connection with
the third-party CPA audit. If the third-party CPA audit shows Tenant has
underpaid Operating Expenses or Real Estate Taxes (or both), in addition to
paying to Landlord the underpayment amount and bearing the third-party CPA audit
costs, Tenant must reimburse Landlord upon demand for all reasonable costs,
expenses and fees incurred by Landlord in connection with such dispute. Tenant
has no right to withhold or reduce any performance by Tenant under the Lease
pending or based upon any audit under this Section 5.04.

of and allow no damage (other than ordinary wear and tear) to the Premises, and
shall keep the Premises in clean, safe and sanitary condition. Tenant shall
segregate, store and dispose of trash and garbage in the manner Landlord
reasonably specifies. Tenant shall promptly notify Landlord of the occurrence of
any event or the existence of any condition that may adversely affect the
Premises or the Building or the occupancy, use or operation thereof If the
Building or the Premises are damaged by Tenant its employees, agents,
contractors, licensees or invitees (including any damage in connection with the
making of an Alteration or Tenant's surrender of the Premises), Tenant shall
promptly notify Landlord and, except to the extent such damage is covered by
nominal and customary extended coverage fire and casualty insurance, shall pay
to Landlord upon demand as additional rent all actual documented costs
(including attorneys' fees and expenses and Landlord's customary overhead,
profit and costs of general conditions) Landlord incurs for the repair and
restoration of the same. Tenant shall promptly remove from all common areas in
or around the Property Tenant's property and items placed or delivered there on
Tenant's behalf

                                  ARTICLE VIII

                       TENANT'S ALTERATIONS AND EQUIPMENT

         8.01 Alterations; Equipment. Except as expressly permitted herein,
Tenant shall not, without in each instance obtaining Landlord's prior consent,
make or permit any Alteration. "Alteration" shall mean any alteration,
installation, removal or improvement of any nature with respect to the Premises
or the Building, or any installation, removal or operation in the Premises of
any equipment or machinery, except for office equipment which (1) is normally
used in modem offices for general office use, and (2) does not (i) require
electrical power in excess of the power requirements for office tenants of the
Building (it being understood that Tenant's connected load for fighting and
outlets shall not exceed five (5) watts per square foot of the Premises); (ii)
require changes to the electrical, water, plumbing, or HVAC systems, (iii) be so
heavy as to create any risk of structural damage to the Building, or (iv) cause
any unreasonable noise, vibration or odor to be transmitted to the structure of
the Building or outside the Premises.

         8.02 Landlord's Consent. Landlord shall not unreasonably withhold,
delay or condition its consent to the making of any Alteration. Landlord shall
not be obligated to give its consent if Landlord believes in good faith that
there is a significant risk that the Alteration (x) would not be made in a
manner comparable in workmanship and quality with the reputation and character
of the Building as a first-class office building, or (y) would materially
adversely affect (i) the structure or the appearance of the Building or the
operation of Budding systems, (ii) Landlord's ability to rent the Premises at
the end of the Term to other tenants at then current market rates, or (iii) the
enjoyment by other occupants of the Building of the benefits of such occupancy.
Landlord's consent to an Alteration, if given, shall be subject in each instance
to the following conditions:

                  (1) Landlord acknowledges that it has approved Tenant's
preliminary plans for the Premises. At least ten (10) days prior to commencing
work, Tenant shall submit to Landlord final plans and specifications therefor
which are consistent with the preliminary plans previously approved by Landlord
and sufficient to obtain a building permit therefor, together with detailed
background


                                       8
<PAGE>   13
information, references and, with respect to contractors and subcontractors,
current financial statements, about the architects, engineers, contractors and
subcontractors to be utilized, and full information regarding the materials to
be used, and Tenant shall promptly submit for Landlord's approval every material
change to the work, the scope of the work or the plans and/or specifications
therefor. A "material charge" shall mean any change which (i) requires a
building permit or permit modification (ii) involves the Building mechanical,
electrical, plumbing, HVAC or other systems, (iii) is likely to adversely affect
any other tenant or occupant of the Building, or (iv) will cost in excess of Two
Thousand Five Hundred Dollars ($2,500.00) to implement. The work shall be
performed by persons and pursuant to plans, specifications and change orders
that Landlord shall have approved (such approval not to be unreasonably withheld
or delayed) and in accordance with all Legal Requirements and requirements of
Landlord's insurance carriers, and Tenant shall at no expense to Landlord insure
continuous compliance with the same and, upon demand, promptly submit to
Landlord satisfactory evidence of such performance (including all permits,
approvals and certificates required therefor). If in connection with making any
Alteration any conflict arises for any reason whatsoever between any persons
under Tenant's direct or indirect control engaged in making the Alteration and
Landlord's contractors, subcontractors or other persons performing work for
Landlord, Tenant shall take all reasonable actions necessary to eliminate such
conflict.

                  (2) All architects and engineers shall continuously carry
errors and omissions insurance in such reasonable amounts as Landlord may
specify, and all contractors and subcontractors shall continuously carry such
amounts of workers' compensation, employer's liability and
commercial/comprehensive general liability insurance as Landlord may reasonably
specify, and, upon demand, Tenant shall furnish Landlord with certificates
evidencing such insurance coverages.

                  (3) Upon completion of the Alteration, Tenant shall furnish
Landlord with enforceable releases of all claims and waivers of all liens
executed by each contractor, subcontractor and material supplier involved in
making the Alteration and paid invoices with respect to the costs thereof. If in
connection with the work any mechanic's materialman's lien is filed against any
portion of the Property, Tenant shall at no expense to Landlord cause such lien
to be released of record within ten (10) days after notice thereof.

                  (4) In connection with the making of the Alteration or the
maintenance or repair thereof, Landlord shall have no obligation to modify,
install or replace any structural component or system contained in the Building
or bear any cost.

                  (5) At the time Landlord consents to any Alteration,
improvements, fixtures and other property, Landlord shall advise Tenant what
Alterations, improvements, fixtures and other property must be removed by Tenant
before the end of the Term.

         10.01 Prohibited Leasehold Transfers.

                  (a) Except as expressly permitted herein, Tenant shall not,
without in each instance obtaining Landlord's prior consent, make or permit any
Leasehold Transfer. "Leasehold Transfer" shall mean, whether voluntarily or by
operation of law, the assignment, transfer, subleasing or encumbering of any
portion of Tenant's rights to and interest in this Lease or the Premises,
including permitting any person to use or occupy any portion of the Premises
(except in connection with Tenant's use of the Premises permitted herein). The
transfer (however effected) of a "controlling ownership interest" in a person
(defined to mean an ownership interest in whatever form by which the holder
thereof exercises effective control over the management and policies of such
person) shall be deemed to be a Leasehold Transfer if such person holds any
interest in this Lease or the Premises; provided that, this sentence shall not
apply to transfers of a controlling ownership interest in any corporation while
the stock of such corporation is publicly traded on the New York or American
Stock Exchanges or while listed in the NASDAQ National Market.



                                       10
<PAGE>   15
                  (b) Any apparent Leasehold Transfer made without Landlord's
consent shall be void. Nevertheless, without waiving any of Tenant's obligations
hereunder or the failure to obtain Landlord's consent Landlord may collect from
any person occupying the Premises in connection with an attempted Leasehold
Transfer all rent due with respect to the portion of the Premises occupied
thereby, and apply the same to the satisfaction of Tenant's obligations
hereunder.

         10.02 Landlord's Consent.

                  (a) In seeking Landlord's consent to a Leasehold Transfer,
Tenant shall at least twenty (20) days before the anticipated effective date of
the Leasehold Transfer submit: (1) the proposed terms and conditions of the
Leasehold Transfer; (2) all relevant information about the proposed transferee;
and (3) satisfactory evidence that the Leasehold Transfer will result in the
Premises being used only as permitted pursuant to Article III hereof.

                  (b) Landlord shall not unreasonably withhold, delay or
condition its consent to any Leasehold Transfer. The reasonableness of any
decision by Landlord to withhold, delay or condition its consent shall be
evaluated in light of all of the relevant circumstances. Landlord shall not be
obligated to give its consent if (i) any event exists which constitutes or which
with the lapse of time or the giving of notice would constitute a material
default hereunder, (ii) Landlord has pursuant to Section 10.03 hereof exercised
its recapture right with respect to the Leasehold Transfer, (iii) the Leasehold
Transfer would result in the Premises being used for a purpose prohibited
hereunder, or (iv) if the Leasehold Transfer is to be effectuated during the
last two (2) years of the Initial Term or the Renewal Term, the rent under the
Leasehold Transfer would be less than the rental rate at which Landlord is then
offering to lease comparable space in the Building. Landlord's consent to a
Leasehold Transfer, if given, shall be subject in each instance to the following
conditions:

                           (1) Tenant shall remain fully and primarily liable
for the performance of all of Tenant's obligations hereunder, whenever such
performance may be required. The transferee with respect to the Leasehold
Transfer shall be subject to any defaults by Tenant hereunder and bound by all
of the terms and conditions of this Article X. Landlord's consent to any
Leasehold Transfer shall not constitute consent to any other or subsequent
Leasehold Transfer, except in each case as permitted herein.

                           (2) Within five (5) days after Tenant receives
Landlord's consent thereto and prior to the effective date of the Leasehold
Transfer, Tenant shall deliver to Landlord a fully executed and acknowledged
instrument in form and substance satisfactory to Landlord, providing for: (i)
the Leasehold Transfer on substantially the same terms and conditions previously
submitted to Landlord; (ii) the transferee's unconditional agreement to be bound
by, and to hold the Premises subject to, all of the terms and conditions hereof
and, if the Leasehold Transfer involves an assignment of all or a portion of the
Premises, to assume a of Tenant's obligations hereunder with respect thereto;
and (iii) an effective date of the Leasehold Transfer not later than six (6)
months after the execution of such instrument. The Leasehold Transfer shall be
effective only in accordance with the terms and conditions of such instrument.
Landlord and Tenant may amend this Lease at any time, and Landlord may take any
other action in connection herewith, and Landlord shall not be obligated to give
any notice to or obtain the consent of any Leasehold Transfer transferee for any
reason whatsoever. The transferee shall automatically be bound by the terms and
conditions of this Lease as amended by Landlord and Tenant at any time.

                           (3) Tenant hereby assigns to Landlord the rents due
from the transferee and authorizes the transferee to pay such rents directly to
Landlord, at Landlord's option, upon the


                                       11
<PAGE>   16
occurrence of any default by Tenant under this Lease, whereupon Landlord may,
without waiving any of Tenant's obligations hereunder, collect and apply such
rents to the satisfaction of such obligations.

                           (4) Tenant shall promptly reimburse Landlord upon
demand for all reasonable costs (including reasonable attorney's fees and
expenses) Landlord incurs in connection with the Leasehold Transfer and the
transferee thereunder.

                           (5) Tenant shall promptly pay Landlord as additional
rent fifty percent (50%) of all of the consideration for the Leasehold Transfer.
"Consideration" shall mean (i) all rents in excess of the rents payable by
Tenant hereunder with respect to the space subject to the Leasehold Transfer,
and all profits in connection with the Leasehold Transfer (including, but not
limited to, all proceeds from the sale or rental of Tenant's fixtures, leasehold
improvements, equipment, furniture, furnishings and other personal property, to
the extent the price or rent paid therefor exceeds the fair market value or the
fair rental value, as the case may be, of the fixtures, improvements, equipment,
furniture, furnishings or other personal property so sold or rented), less (ii)
all reasonable out-of-pocket expenses Tenant incurs in effecting the Leasehold
Transfer. Upon demand, Tenant's chief financial officer shall promptly certify
to Landlord accountings setting forth the character, amount and date of receipt
or expenditure of each item of consideration and expense, and submit such
supporting documentation as Landlord may reasonably request.

         10.03 Recapture. Landlord may, with respect to each Leasehold Transfer
for which Landlord's consent is required, elect to: (1) become Tenant's
subtenant with respect to the space subject to the proposed Leasehold Transfer,
or (2) terminate Tenant's leasehold interest in such space, in either case
effective thirty (30) days after Landlord notifies Tenant of Landlord's exercise
of its recapture right with respect to the Leasehold Transfer. With respect to a
Leasehold Transfer for which Tenant has requested Landlord's consent, Landlord
shall so notify Tenant within twenty (20) days after receiving Tenant's request
or Landlord shall be deemed to have declined to exercise its recapture right
with respect to such Leasehold Transfer. If Landlord declines to exercise its
recapture right with respect to a Leasehold Transfer, Landlord's consent to the
Leasehold Transfer shall nonetheless be required. If Landlord exercises its
recapture right with respect to a Leasehold Transfer: (i) Landlord may at
Tenant's expense reconfigure the Premises to provide public access to the
recaptured space; and (ii) Tenant shall promptly execute and deliver to Landlord
(x) if Landlord elects to sublet the space, a sublease in a form reasonably
satisfactory to Landlord and providing that Landlord shall be required during
the term of the sublease to abate all rents accruing with respect to the space,
or (y) if Landlord elects to terminate Tenant's leasehold interest in the space,
an amendment hereto in a form reasonably satisfactory to Landlord and providing
for such termination. Landlord may, without incurring any liability to Tenant,
lease or sublet the recaptured space to any person (including any person which
Tenant proposed as a transferee under a Leasehold Transfer).

                                   ARTICLE XI

                              RIGHT OF FIRST OFFER

         11.01 Right of First Offer. Provided no Event of Default has occurred
under this Lease, and subject to the right of Landlord to renew the lease of any
tenant currently leasing space on the eighth (8th) floor on the date of this
Lease, Tenant shall have the right of first offering to lease contiguous office
space located on the eighth (8th) floor of the Building (the "Additional
Premises"). Such right shall arise whenever, during the Term the Landlord wishes
to lease the Additional Premises. Landlord shall provide Tenant with not less
than thirty (30) days written notice ("Landlord's Notice") setting forth the
date the Additional Premises will be


                                       12
<PAGE>   17
available. Tenant shall exercise its right of first offering (if at all) by
written notice ("Tenant's Notice"), delivered to Landlord not later than twenty
(20) days after delivery of Landlord's Notice to Tenant, and agreeing to lease
the Additional Premises commencing on the date the Additional Premises are
available as set forth in Landlord's Notice. In the event the Tenant's Notice is
not timely given, Tenant shall be deemed to have waived its right of first
offering and Landlord may proceed to lease the Additional Premises to third
parties. Prior to the commencement of the term for the Additional Premises,
Tenant agrees to execute an amendment to this Lease incorporating the Additional
Premises into this Lease as part of the Premises on the following terms and
conditions:

                  (a) If the Tenant exercises its right of first offer for the
Additional Premises during the first three Lease Years the terms and conditions
applicable to the Additional Premises shall be the same terms and conditions as
the terms of this Lease including rental rates. The term for the Additional
Premises will be co-terminous with the Term under this Lease. The Tenant
allowance shall be prorated based on the number of months remaining in the first
three Lease Years.

                  (b) If the Tenant takes the Additional Premises during the
last six Lease Years, the rental rate, Tenant allowance and other terms
applicable to the Additional Premises (other than Lease Term, which will be
co-terminous with the Lease Term for the Premises) will be subject to the then
current market terms and conditions for similar space within the Building
(taking into consideration the applicable Lease Term).

                                  ARTICLE XII

                               SURRENDER; HOLDOVER

         12.01 Surrender of the Premises.

                  (a) At the end of the Term Tenant shall deliver to Landlord
exclusive possession of the Premises, broom clean and in "as is" condition on
the Commencement Date, ordinary wear and tear excepted; provided, however, that
Tenant shall remove from the Premises and the Building all property specified in
subsection (b) below. The delivery of keys to the Premises to anyone (including
delivery of the keys to Landlord so that Landlord may sublet the Premises for
Tenant) shall not terminate this Lease or effect a surrender of the Premises.

                  (b) Tenant may not, without Landlord's consent, remove any
Alterations, other improvements to the Premises or fixtures (including all such
improvements and fixtures existing on the Commencement Date), which cannot be
removed without damage to the Premises or the Building. Tenant shall, at no
expense to Landlord and subject to Article VIII hereof, remove any Alteration,
improvements, fixtures and other property which, pursuant to Section 8.02(5)
Landlord has advised Tenant must be removed before the end of the Term. Where
furnished by Tenant or at its expense, all moveable furnishings and trade
fixtures shall remain Tenant's property, which Tenant may at no expense to
Landlord remove before the end of the Term. Alterations, improvements, fixtures
and other property, which Tenant is required pursuant to Section 8.02(5) or
permitted to remove from the Premises and which remain on the Premises after the
end of the Term, shall be deemed to be abandoned, and Landlord may, at Tenant's
expense and without incurring any liability (as a bailee or otherwise) to
Tenant, remove and dispose of the same in any fashion.



                                       13
<PAGE>   18
                  (c) Upon demand, Tenant shall promptly pay to Landlord as
additional rent all reasonable direct costs (including reasonable attorneys'
fees and expenses), Landlord incurs in connection with the removal of property
from the Premises and the Building and the disposal thereof pursuant hereto, and
the repair of any damage to the Premises or the Building occasioned thereby.

         12.02 Holdover. If Tenant fails to surrender the Premises at the end of
the Term, at Landlord's option the Tenant shall become a month-to-month tenant
subject to all of the terms and conditions hereof, except that Tenant shall on
account of such tenancy pay in advance on the first day of each calendar month,
without demand therefor, a monthly rental equal to the greater of (i) two
hundred percent (200%) of the aggregate amount of Base Rent plus Rent
Adjustments in effect immediately preceding the end of the Lease Term, or (ii)
the fair market rental value of the Premises, prorated on a monthly basis;
provided that, notwithstanding the foregoing, during the first (1st) ninety (90)
days of any such monthly tenancy, Tenant shall pay a monthly rental equal to the
greater of (i) one hundred fifty percent (150%) of the aggregate amount of Base
Rent plus Rent Adjustments in effect immediately preceding the end of the Lease
Term, or (ii) the fair market rental value of the Premises. Such tenancy may be
terminated by either party upon thirty (30) days prior notice. During such
tenancy Landlord may with respect to any default hereunder exercise all rights
and remedies provided for herein. Notwithstanding the foregoing, any time prior
to Landlord's acceptance of rent from Tenant as a monthly tenant hereunder,
Landlord, at its option, may forthwith re-enter and take possession of the
Premises by any means permitted by law, TENANT HEREBY WAIVING ANY NOTICE TO
QUIT; provided, however, that (i) Tenant shall pay Landlord as damages (but not
as rent) the greater of the fair market value rent for the Premises or two (2)
times (1.5 times, during the first 90 days of such holdover) the Base Rent plus
all Additional Rent payable for the last month of the Term, for each month or
portion thereof that Tenant remains in possession following the Expiration Date,
and (ii) Tenant shall defend, indemnify and hold Landlord harmless from and
against any and all claims, losses, liabilities or damages resulting from
Tenant's failure to surrender possession of the Premises on the Expiration Date
(including, but not limited to, claims made by any succeeding tenant).

                                  ARTICLE XIII

                         QUIET ENJOYMENT; SUBORDINATION

         13.01 Covenant of Quiet Enjoyment. Subject to all of the terms and
conditions of this Lease, Tenant's interest in this Lease and possession of the
Premises shall not be terminated during the Term by Landlord or any person
claiming an interest in the Premises, the Building or the Land through Landlord.
Neither Landlord's inability to perform Landlord's obligations hereunder
(including the furnishing of utilities and HVAC) by virtue of any circumstance
beyond Landlord's reasonable control nor the taking of any action in or around
the Premises permitted hereunder, shall constitute an actual or constructive
eviction of Tenant in whole or in part or provide any grounds (including an
interruption or reduction in Tenant s business) for an abatement of rent or for
Landlord's liability; provided that, notwithstanding the foregoing, if Landlord
fails to provide HVAC or electric service to the Premises for a period in excess
of five (5) consecutive business days, Landlord agrees to thereafter abate the
Rent payable hereunder for so long as Tenant cannot and in fact does not use the
Premises as a result of such failure.

         13.02 Subordination.

                  (a) This Lease shall be automatically subordinate to and bound
by each underlying lease, deed of trust and mortgage (including all advances
made thereunder at any time), and all amendments thereto and renewals,
extensions, modifications, consolidations, replacements and transfers thereof
(whether by sale, assignment, foreclosure or otherwise), now or hereafter
affecting any portion of the Land, the Building or the Premises (in each case, a
"Superior Instrument"). Tenant may not terminate this Lease, and this Lease
shall remain in effect upon any sale or assignment or foreclosure upon, any
portion of the Property pursuant to any Superior Instrument, or upon the
termination of any Superior Instrument. Notwithstanding any other provision
hereof, no holder of a Superior Instrument shall be liable for any act, omission
or default of Landlord, subject to any offsets, claims or defenses which Tenant
may have against Landlord, bound by any rent that Tenant paid to Landlord more
than one (1) month in advance, or bound by any amendment, waiver or termination
of this Lease, unless consented to by such holder in writing. If by virtue of
Landlord's default Tenant may obtain an abatement of rent remedy such default or
terminate this Lease, Tenant shall not exercise such right(s) unless Tenant
first notifies each holder of a Superior Instrument (which notice may be given
simultaneously with any notice Tenant gives to Landlord), which has furnished
Tenant with its address, and such holder fails to initiate promptly and use
reasonable efforts to cure such Landlord's default. If in connection with any
financing of any portion of the Property or improvements thereto the holder of a
Superior Instrument requires modifications to this Lease, Tenant shall not
unreasonably withhold, delay or condition Tenant's consent to such
modifications, so long as such modifications do not increase the rents payable
by Tenant hereunder, reduce or extend the Term, reduce or increase the area of
the Premises, or materially adversely affect Tenant's rights and obligations
hereunder. The holder of a Superior Instrument may subordinate such Instrument
to this Lease at any time and Tenant hereby consents to such subordination. Upon
request Tenant shall execute, acknowledge and deliver in recordable form such
instruments effecting such subordination.

                  (b) Upon request of the holder or beneficiary of any Superior
Instrument (each a "Lender"), Tenant shall agree in writing that no action taken
by such holder or beneficiary to enforce said Superior Instrument shall
terminate this Lease or invalidate or constitute a breach of any of the
provisions hereof and Tenant will attorn to such Lender, or to any purchaser of
the Budding or Property at any foreclosure sale or sale in lieu of foreclosure,
for the balance of the Term of this Lease and on all other terms and conditions
herein set forth. Tenant, by entering into this Lease, covenants and agrees that
(a) upon the written direction of Lender it shall pay all rents arising under
this Lease as directed by such Lender; and (b) in the event such Lender enforces
its rights under the Superior Instrument due to a default by Landlord this Lease
is not extinguished by a foreclosure of the Superior Instrument, and Tenant will
upon request of any person succeeding to the interest of Landlord in the
Property ("successor in interest") as the result of said enforcement,
automatically attorn to such successor in interest, without any change in terms
or other provisions of this Lease; provided, however, that said successor in
interest shall not be: (i) bound by any payment of rent or additional rent for
more than one month in advance, except payments in the nature of security (but
only to the extent such payments have been delivered to such successor in
interest); (ii) bound by any modifications to the Lease (including, but not
limited to, any agreement providing for early termination or cancellation of the
Lease) made without any requisite consent of the Lender or any such successor in
interest; (iii) liable for damages for any act or omission of any prior landlord
(including, but not limited to, Landlord); or (iv) subject to any offsets or
defenses which Tenant might have against any prior landlord (including, but not
limited to, Landlord). Notwithstanding the foregoing, Tenant shall retain any
rights it may have to proceed against the original Landlord.

<PAGE>   20
         13.03 Subordination, Attornment and Non-Disturbance Agreement; Estoppel
Certificate. Within ten (10) days after demand therefor by Landlord, the holder
or beneficiary of any Superior Instrument or any of their successors in
interest, Tenant shall execute, acknowledge and deliver in recordable form: (1)
a Subordination, Attornment and Non-Disturbance Agreement and/or (2) an estoppel
certificate substantially in the form of Exhibit G attached hereto.

                                  ARTICLE XIV

                         FIRE OR CASUALTY; CONDEMNATION

         14.01 Fire or Casualty.

                  (a) The occurrence of any fire or other casualty shall
constitute no basis for the termination of this Lease or any abatement of rent,
except as expressly provided for herein. If the Building is damaged by fire or
other casualty (whether or not the Premises are damaged) and if Landlord obtains
a reasonable professional estimate that the cost of restoring the Building would
exceed fifty percent (50%) of the full insurable value of the Building, Landlord
may, by notice to Tenant within sixty (60) days after such fire or other
casualty, terminate this Lease without incurring any liability to Tenant. If
Landlord fails so to notify Tenant, Landlord shall use reasonable efforts to
repair the Building (including the restoration of the demising walls of the
Premises and Building services to the outside perimeter of the Premises) with
reasonable dispatch, allowing for the adjustment and settlement of insurance
claims, the preparation of plans and specifications, the obtaining of
governmental approvals and certificates, the obtaining of contractors and
laborers and any other delay. So long as Landlord restores the Building so it is
suitable for substantially the same uses, Landlord shall not be obligated to
duplicate the original construction or design of the Building. Landlord shall
not be obligated to repair, restore or replace: (1) any property within the
Premises; (2) any damage that occurs during the last year of the Term (as
extended, if at all, pursuant to the exercise of any Renewal Option); or (3) any
damage for the repair of which insurance proceeds are not available. Tenant
shall cooperate fully with all repairs made to the Building (including removing
Tenant's moveable property and trade fixtures from the Premises as soon as
practicable to clear the way therefor).

                  (b) Rents hereunder shall be abated during the period and
to the extent that a material portion of the Premises is rendered untenantable
because of a fire or other casualty. If more than thirty percent (30%) of the
Premises is rendered untenantable by fire or other casualty and Landlord cannot,
given Tenant's full cooperation, substantially complete such repairs so that the
Premises are rendered substantially tenantable within one hundred eighty (180)
days after such fire or other casualty, then Tenant may, by notice to Landlord,
terminate this Lease with thirty (30) days of the date of such casualty.

         14.02 Condemnation.

                  (a) The occurrence of any condemnation or taking pursuant to
the exercise of the power of eminent domain, or any sale in lieu thereof, shall
constitute no basis for the termination of this Lease or any abatement of rent,
except as expressly provided for herein. If the entire Premises are lawfully
condemned or taken, this Lease shall terminate as of the date title vests


                                       16
<PAGE>   21
pursuant to such condemnation or taking, and Tenant shall have no claim for the
value of the unexpired portion hereof. If fifteen percent (15%) or more of the
Premises, or the means of access thereto, are lawfully condemned or taken,
Tenant may, by notice to Landlord within thirty (30) days after the date title
vest pursuant to such condemnation or taking, terminate this Lease. If any
portion of the Premises is lawfully condemned or taken and this Lease is not
terminated as provided herein, Tenant shall be entitled to a rent abatement with
respect thereto, commencing the date title vests pursuant to such condemnation
or taking. However, if any portion of the Premises is condemned or taken without
compensation to effect compliance with any Legal Requirement and if such
compliance is Tenant's obligation hereunder, Tenant shall be entitled to no rent
abatement. If only a portion of the Building is lawfully condemned or taken and
if such condemnation or taking would permit Landlord to terminate leases with
respect to a significant portion of the leased space in the Building, Landlord
may, by notice to Tenant within thirty (30) days after the date title vests
pursuant to such condemnation or taking, terminate this Lease (whether or not
the Premises are affected by such condemnation or taking).

                  (b) Landlord shall receive the entire award made in each
proceeding in connection with the condemnation or taking of the Building, the
Premises or any portion thereof (including any award made for the value of
Tenant's interest in this Lease or the Premises), and Tenant hereby assigns to
Landlord any and all right, title and interest Tenant may have now or in the
future to any such award or any part thereof Tenant may pursue a separate claim
against the condemning authority, so long as such claim does not in any way
diminish the award or compensation payable to or recoverable by Landlord in
connection with such taking or condemnation.

                                   ARTICLE XV

                   LANDLORD'S ACCESS, REPAIRS AND ALTERATIONS

         15.01 Access, Repairs; Alterations. Tenant shall furnish Landlord with
keys and other means of effecting entry into all portions of the Premises at all
times. Upon prior notice to Tenant Landlord may enter the Premises from time to
time to: (1) inspect, maintain, clean, repair, make alterations to and install
equipment in the Premises (and for such purposes Landlord may bring into and
store in the Premises reasonable quantities of equipment and materials); (2)
comply with the demand of any person submitting reasonable evidence of a lawful
purpose and a legal entitlement to access to the Premises; (3) show the Premises
to potential purchasers and mortgagees of the Building; and (4) within the last
twelve (12) months of the Term, show the Premises to prospective tenants.
Landlord may change the arrangement and location of entrances, passageways,
doorways, corridors, elevators, stairways, toilets and other parts of the
Premises and the Building, so long as doing so will not substantially or
materially adversely interfere with Tenant's access to the Premises. In any
emergency, Landlord may without notice enter the Premises by any and all means
which are reasonable under the circumstances and take all necessary or desirable
measures to resolve the emergency. In resolving an emergency, Landlord shall not
be liable for any damage to Tenant's property, so long as such damage is not
caused by Landlord's gross negligence or willful misconduct in taking actions
permitted by this Section, Landlord shall use reasonable efforts to accommodate
Tenant, but shall not be obligated to incur overtime or premium costs.

                                  ARTICLE XVI

                     INSURANCE; WAIVER OF CLAIMS; INDEMNITY

         16.01 Insurance Generally.

                  (a) Throughout the Term, Landlord and Tenant shall each obtain
and maintain in effect the insurance coverages specified in this Article, by
virtue of insurance policies underwritten only


                                       17
<PAGE>   22
by solvent insurance companies authorized to do business in the District of
Columbia. The insurance policies that Tenant is required to carry hereunder
shall: (1) be written as primary coverage and not contributing with or in excess
of any coverages Landlord may carry, (2) contain an endorsement requiring each
insurer to provide thirty (30) days prior written notice to Landlord before any
cancellation or material change in the type or amount of any coverage
thereunder, and (3) designate Landlord as an "additional insured" and, at
Landlord's request, if available, include a standard mortgagee clause for the
benefit of any person holding an insurable interest in the Premises or the
Building.

                  (b) Tenant shall give Landlord prompt notice and a detailed
description of each event which might constitute the basis for a material claim
under any of the insurance policies required to be carried hereunder. Tenant
shall cooperate fully with Landlord in prosecuting and resolving all such
claims. Whether or not Tenant fully complies with all of the provisions of this
Article, the description of required insurance policies and related maximum
coverage amounts set forth herein shall not operate to limit Tenant's liability
under any provision of this Lease. On an annual basis, if requested by Landlord,
Tenant shall promptly furnish Landlord certificates evidencing the insurance
coverages required to be maintained hereunder and the payment of premiums
therefor.

                  (c) Tenant shall not act or fail to act, or permit any person
under Tenant's reasonable control to act or fad to act, in any way which might
invalidate or reduce any coverages or increase the premiums therefor under any
insurance policies required to be carried hereunder or carried by Landlord with
respect to the Property or the use or operation thereof. If any insurance
carrier or board of underwriters determines that any such coverage shall be
invalidated or reduced or premiums therefor shall be increased as a direct or
indirect result of any act or omission of Tenant or any person under Tenant's
reasonable control (whether or not such act or omission would otherwise
constitute a default hereunder), Tenant shall promptly pay to Landlord as
additional rent the costs of securing comparable coverages and the increased
premiums.

                  (d) Each party hereunder shall, at its own expense, cause each
insurance policy that it obtains in connection with this Lease, the Premises or
the Building to contain an endorsement providing that: (1) the issuer of such
policy waives all rights of subrogation against the other party; and (2) such
policy shall not be invalidated if the insured, prior to a loss, waives in
writing all rights of recovery against any person for losses covered by such
policy.

         16.02 Casualty Insurance. Tenant shall maintain a
commercial/comprehensive general liability policy with a limit of at least
$3,000,000 per occurrence and $3,000,000 in the general aggregate and the
following coverages: (1) a broad form, commercial liability endorsement; (2)
endorsements covering premises/operations, independent contractors and host
liquor liability; and (3) a broad form contractual liability endorsement
insuring the performance of Tenant's indemnification obligations hereunder.

         16.03 Property Insurance. Tenant shall carry all risk property
insurance in such amounts as shall be sufficient to cover the repair,
restoration and replacement of all Alterations, other improvements to the
Premises and fixtures (including all such improvements and fixtures existing on
the Commencement Date). Tenant shall carry such other insurance as Tenant may
deem necessary or desirable to protect Tenant's property located in or around
the Premises. Landlord shall have no obligation to insure the Premises or
Tenant's property. Landlord shall obtain and maintain all risk property
insurance in an amount equal to the full replacement cost of the Building.



                                       18
<PAGE>   23
         16.04 Waiver of Claim. Each party hereunder hereby waives all rights of
recovery against the other party for any claim, loss, injury or expense in
connection with any property damage or loss, to the extent such claims are
covered by casualty insurance maintained (or required hereby to be maintained)
by the injured party, each party hereby agreeing to look only to its insurance
policies for recovery in respect of any such property damage or suffered by it.
Notwithstanding anything herein contained to the contrary, Landlord shall not be
liable for any claim, loss, injury or expense (including any claim for
compensation for reduction in the value of Tenant's leasehold or interest in the
Premises, inconvenience or annoyance to Tenant, injury to Tenant's business or
property, or, except as expressly set forth herein, rent abatement in connection
with Landlord's taking any action permitted hereunder) in connection with this
Lease, the Property, or Tenant's use or occupancy of the Premises. In any event
Landlord's aggregate liability in connection with this Lease, the Property and
Tenant's use and occupancy of the Premises shall be limited as set forth in
Section 19.10 and in no event shall Landlord be liable for any indirect or
consequential damages for any reason whatsoever.

         16.05 Indemnity. Subject to the provisions of Section 16.04 above,
Tenant hereby indemnifies and shall hold harmless and defend Landlord, its
partners, directors, officers, employees, contractors and agents against all
claim, liabilities, losses, injuries and expenses (including attorneys' fees and
expenses and the costs of investigating and/or settlement claims) arising
directly or indirectly out of. (1) the occurrence of any event within the
Premises; (2) any act or omission of Tenant, its employees or agents, or any
contractor performing work in or to, or any licensee operating within, the
Premises; (3) alterations to, or installation or operation of equipment in, any
portion of the Building or the Premises by Tenant or a Leasehold Transfer
transferee; (4) any breach of Tenant's representations, warranties or covenants
hereunder, or (5) any act or failure to act by Tenant or any Leasehold Transfer
transferee invalidating or reducing any coverages under any insurance policies
required to be carried hereunder or carried by Landlord with respect to the
Property or the use or operation thereof. The foregoing indemnity shall not be
applicable insofar as Landlord incurs a loss or expense through its gross
negligence or willful misconduct. The provisions of this Section shall survive
termination of Tenant's right of possession to the Premises and the end of the
Term.

         16.06 Landlord's Insurance. Landlord agrees to carry broad form fire
and casualty insurance with respect to the Budding, in such amounts and form as
required by Landlord's mortgagee with respect to the Building from time to time,
but in all events in an amount sufficient to satisfy any insurance requirements.

                                 ARTICLE XVIII

                     INSOLVENCY; EVENTS OF DEFAULT; REMEDIES

         18.01 Events of Insolvency.

                  (a) "Event of Insolvency" means: (1) Tenant (including, with
respect to Events of Insolvency, any guarantor of Tenant's obligations
hereunder) becomes bankrupt or insolvent under any applicable federal, state or
local state or rule of law (collectively, "Insolvency Laws"); (2) Tenant files a
petition, or acquiesces in a petition filed, under any Insolvency Law; (3) an
involuntary petition is filed against Tenant under any Insolvency Law, which is
neither dismissed within sixty (60) days after such filing or results in the
issuance of an order for relief against Tenant whichever occurs earlier; (4) a
receiver or trustee is appointed for, or a foreclosure action is instituted
upon, all or a substantial portion of Tenant's property or assets; or (5) Tenant
makes or consents to an assignment or other conveyance in trust for the benefit
of creditors.

                  (b) This Lease shall not be considered an asset of Tenant's
estate in bankruptcy or insolvency. Upon an Event of Insolvency, Landlord may by
notice to Tenant terminate this Lease; provided that Tenant shall remain liable
for all rents and other damages payable hereunder without prejudice to
Landlord's right in any proceeding under any Insolvency Law to prove and obtain
as liquidated damages the maximum such amount permitted thereby; and provided,
further, that if, by virtue of any Insolvency Law, Landlord is not permitted to
enforce such termination, the following provisions shall apply, to the extent
enforceable:

                           (1) If there is an uncured default under this Lease,
no receiver or trustee may assume and retain, or assign, this Lease unless at
the time of such assumption or assignment the receiver or trustee (x) cures such
default or provides adequate assurance to Landlord's reasonable satisfaction
that such default will be cured promptly, (y) compensates, or provides adequate
assurance to Landlord's reasonable satisfaction that such receiver or trustee
will promptly compensate, Landlord for any actual pecuniary loss incurred by
Landlord as a result of such default, and (z) provides adequate assurance to
Landlord's reasonable satisfaction of the future performance of all of Tenant's
obligations under this Lease.

                           (2) No receiver or trustee may require Landlord to
furnish any services or supplies required to be furnished under this Lease
unless (x) Landlord is compensated therefor before such services or supplies are
furnished, or (y) such receiver or trustee assumes this Lease as provided in
clause (1) above.

         18.02 Events of Default. The occurrence of an Event of Default shall
constitute a breach of Tenant's obligations hereunder. "Event of Default" shall
mean any of the following:

                  (a) the failure to pay Landlord an installment of Base Rent or
any Rent Adjustment within five (5) days after notice to Tenant of the failure
to make such payment when due, or the failure to make any other payment of
additional rent within five (5) days after Landlord's second demand therefor,

                  (b) the transfer by operation of law or otherwise of any
portion of Tenant's interest herein or in any portion of the Premises to any
person other than as expressly permitted hereunder,



                                       20
<PAGE>   25
                  (c) by virtue of Tenant's interest herein or occupancy of the
Premises or any act or omission of Tenant, its employees, agents, contractors,
invitees or licensees, or any transferee under a Leasehold Transfer, any portion
of the Property or Landlord's interest therein becomes subject to any claim,
lien or other encumbrance which is not irrevocably released and removed of
record at no expense to Landlord within thirty (30) days thereafter,

                  (d) the failure to maintain insurance in the amounts and
coverages required to be maintained by Tenant hereunder,

                  (e) the abandonment or vacating of the Premises for a
continuous period of thirty (30) days or more, except as expressly permitted
hereunder, provided that, abandonment of the Premises shall not be deemed an
Event of Default if (i) Tenant notifies Landlord in writing of Tenant's intent
to vacate or abandon not less than thirty (30) days in advance, (ii) Tenant
obtains and provides to Landlord prior to vacating all necessary endorsements
required to ensure that Tenant's insurance with respect to the Premises shall
remain in full force and effect notwithstanding such abandonment, (iii) Tenant
takes all commercially reasonable steps necessary to secure the Premises against
unauthorized entry during the period of such vacancy or abandonment, and (iv)
Tenant indemnifies Landlord against any claim, cost, damage, expense, fee,
liability or suit arising from or out of, or in connection with, such vacating
or abandonment.

                  (f) the occurrence of any breach of any of Tenant's
representations, warranties or covenants hereunder (excluding the Events of
Default described above) or of a material breach under any other agreement
between Landlord and Tenant relating to the Premises or under any other lease
between Tenant and Landlord: (1) which breach is not cured within thirty (30)
days thereafter, or (2) if such breach cannot be cured with reasonable efforts
within such thirty-day period and if extending the cure period will not (i)
subject Landlord to the risk of a civil claim or criminal liability or the
Property to any claim or encumbrance, or (ii) result in the termination or
impairment of any Superior Instrument, the failure of Tenant to initiate the
cure thereof within such thirty-day period and to continuously and diligently
prosecute the same to completion; or

                  (g) the occurrence more than twice in any twelve-month period
of any event which would have constituted an Event of Default but for the curing
thereof within the applicable grace period provided for herein.

         18.03 Remedies; Waivers.

                  (a) In the event of any breach of any of Tenant's
representations, warranties or covenants hereunder, Landlord may pursue any and
all remedies available at law or in equity. Upon demand, Tenant shall pay
Landlord as additional rent: (1) all damages, losses and expenses Landlord
reasonably incurs as the result of each such breach, including (i) reasonable
attorneys' fees and expenses in enforcing Landlord's rights and remedies
hereunder, and (ii) in connection with any attempt by Landlord to re-let the
Premises, attorneys' fees and expenses, advertising costs, brokerage
commissions, lease concessions, improvement allowances, architects' and
engineers' fees and expenses; and (2) the aggregate amount of all abatements of
Base Rent, tenant allowances under the Work Letter and all other concessionary
payments to Tenant.

                  (b) Upon the occurrence of an Event of Insolvency or Event of
Default, Landlord may, without incurring any liability to Tenant: (1) by notice
to Tenant terminate this Lease; or (2) with or without terminating this Lease
and without notice to Tenant to quit or making a demand for rent or possession
(such notices and demands being hereby waived by Tenant), enter into and take


                                       21
<PAGE>   26
possession of the Premises pursuant to summary dispossession proceedings or any
other action at law. Without limiting whatsoever any of its rights and remedies
hereunder, Landlord may retain all monies (including the Security Deposit) that
Tenant has paid, and shall credit the same against rents payable hereunder.
Landlord shall use reasonable efforts to re-let the Premises for Tenant's
benefit, in which event Landlord shall credit against rent payable hereunder,
but only to the extent thereof, the rent Landlord collects on or before the
Expiration Date from such reletting.

                  (c) Landlord may initiate legal proceedings against Tenant at
any time and from time to time to recover any and all rent due hereunder, and
the bringing of any such proceedings shall not preclude Landlord from bringing,
simultaneously and in the future, other proceedings against Tenant in connection
with this Lease. No provision of this Lease shall be deemed to require Landlord
to postpone any legal or equitable proceedings until the end of the Term. Tenant
hereby waives all rights of redemption available under any present or future
law, regardless of the grounds that might support any claim to such rights.
Landlord and Tenant hereby waive trial by jury in any action, proceeding or
counterclaim arising in connection with this Lease, the relationship of Landlord
and Tenant, or Tenant's use or occupancy of the Premises.

         18.04 Intentionally Deleted.

         18.05 Late Payments; Interest. Tenant shall promptly pay to Landlord as
additional rent with respect to any amount due hereunder and not paid interest
accruing at an annual rate equal to the lesser of eighteen percent (18%) and the
maximum rate, if any, that Landlord may charge Tenant under applicable law (the
"Interest Rate"), from the date upon which such amount is due (as specified
herein with respect to installment payments and, with respect to other rent
payments, as specified in Landlord's demand to Tenant for payment as provided
for herein). If Tenant shall fail to pay any installment of Base Rent, Real
Estate Taxes, Operating Expenses, or annual Base Rent Adjustments when due and
payable as provided for herein, a five percent (5%) late charge shall be added
to each such late installment.

         18.06 Landlord's Right to Cure Defaults. Upon a breach of any of
Tenant's obligations hereunder, Landlord may, at Tenant's expense and without
limiting Tenant's liability for such breach and without incurring any liability
to Tenant, take all necessary or desirable actions (including entering the
Premises) to cure such breach. Upon demand, Tenant shall pay to Landlord as
additional rent (1) all direct and indirect costs (including the fees and
disbursements of attorneys, architects and engineers and Landlord's customary
overhead, profit and costs of general conditions) Landlord incurs in taking such
actions, together with (2) interest thereon, which interest shall accrue at the
Interest Rate from the date Landlord incurs such costs.

                                  MISCELLANEOUS

         19.01 Rules and Regulations. Tenant shall comply, and cause all persons
under Tenant's reasonable control to comply, with the rules and regulations set
forth in Exhibit H attached hereto and such additional rules and regulations as
Landlord may reasonably adopt (collectively, the "Rules and Regulations"). If

Landlord's failure to enforce the Rules and Regulations against any such tenant
shall not constitute a waiver of Tenant's obligations hereunder.

         19.02 Brokerage. Tenant represents and wan-ants that neither it nor its

Lease or the transactions contemplated hereby. Landlord shall have no obligation
to compensate the Brokers, other than the compensation Landlord shall pay to
Landlord's Broker pursuant to the separate agreement between Landlord's Broker
and Landlord. By executing this Lease, Tenant's Broker releases Landlord from
all claims whatsoever in connection with the negotiation and execution of this
Lease and all options Tenant may exercise hereunder. Tenant's Broker agrees to
look to Landlord's Broker for compensation pursuant to a separate agreement
between Landlord's Broker and Tenant's Broker.

         19.03 Transfers of Title. If title to the Building or any other portion
of the Property is transferred or the leasehold estate in the entire Building
becomes vested in another person (whether voluntarily or by operation of law),
thereafter and upon notice to Tenant and the delivery of the Security Deposit if
any, to the transferee, the transferor shall be entirely released from and
relieved of all existing and future covenants, obligations and liabilities
hereunder so long as transferee is obligated to perform all of Landlord's
obligations hereunder. The provisions of this Section shall be self-executing
and deemed to be a covenant running with the land.

19.10(b), for the performance of Landlord's obligations under this Lease and for
the satisfaction of any right of Tenant for the collection of any claim,
judgment or other judicial determinations (whether at law or in equity) or
arbitration award requiring the payment of money, and neither MMPI nor any of
its agents, incorporators, shareholders, beneficiaries, trustees, officers,
directors, employees, partners, principals (disclosed or nondisclosed) or
affiliates or any of their respective assets or property shall be subject to any
claim, judgment, levy, lien, execution, attachment or other enforcement
procedure (whether at law or in equity) for the satisfaction of Tenant's rights
and remedies under or with respect to this Lease or under law, or Tenant's use
and occupancy of the Premises or any liability or obligation of Landlord to
Tenant. The limitation of MMPI's liability under this Lease, including any
waiver of subrogation rights, shall apply with equal force and effect to, and as
a limitation on and a waiver of any liability of MMPI.

of any partners, beneficiaries, managers, members, stockholders, officers,
employees or agents of Landlord) shall be subject to levy, execution or other
procedures for the satisfaction of Tenant's remedies. No personal liability is
assumed by, nor shall at any time be asserted or enforceable against Landlord,

members, any successor owner or their respective successors or assigns or the

or partners thereof, or the agents or employees of any of them on account of
this Lease or any covenant, undertaking or agreement of Landlord in this Lease
contained.

         19.11 Affirmative Action Program. Tenant acknowledges receipt of a copy
of Section III of the Affirmative Action Program submitted with respect to the
Building (the same being attached hereto as Exhibit J). Tenant is not a party to
this program and this Lease is not subject to the terms thereof. Nonetheless,
Landlord encourages Tenant to utilize the procedures contained in said Section
III regarding the dissemination of employment information.

         IN WITNESS WHEREOF, each of the undersigned has caused its duly
authorized representative to execute this Lease under seal as of the date first
written above.

cleanliness of the leased premises, provided same are in writing and are not in
conflict with this lease.

or destroyed or rendered partially unfit for occupancy by fire or other

defaults in the performance of any obligations or covenants herein, Landlord may

                  (b) Successors and Assigns. With respect to Seller, this
Agreement shall not be assignable; provided, however, that any representations
and warranties that survive Closing pursuant to the terms hereof shall be
binding on Seller's successors and assigns. This Agreement shall be binding upon
and shall inure to the benefit of Buyer and its heirs, personal representatives,
successors and assigns.

                  (c) Entire Agreement; Governing Law. This Agreement contains
the entire understanding of the parties with respect to the subject matter
hereof, supersedes all prior or other negotiations, representations,
understandings and agreements of, by or among the parties, express or implied,
oral or written, which are fully merged herein. The express terms of this
Agreement control and supersede any course of performance and/or customary
practice inconsistent with any such terms. Any agreement hereafter made shall be
ineffective to change, modify, discharge or effect an abandonment of this
Agreement unless such agreement is in writing and signed by the party against
whom enforcement of such change, modification, discharge or abandonment is
sought. This Agreement shall be governed by and construed under the laws of the
State of Florida.

                  (d) Provisions Separable. The provisions of this Agreement are
independent of and separable from each other, and no provision shall be affected
or rendered invalid or unenforceable by virtue of the fact that for any reason
any other provision may be invalid or unenforceable in whole or in part.

                  (e) Gender, etc. Words used in this Agreement, regardless of
the number and gender specifically used, shall be deemed and construed to
include any other number, singular or plural, and any other gender, masculine,
feminine or neuter, as the context indicates is appropriate.

                  (f) Counterparts. This Agreement may be executed in any number
of counterparts, each of which shall be deemed to be an original as against any
party whose signature appears thereon, and all of which shall together
constitute one and the same instrument. This Agreement shall be binding when one
or more counterparts hereof, individually or taken together, shall bear the
signatures of all of the parties reflected on this Agreement as the signatories.

                  (g) No Waiver. Neither the failure nor any delay on the part
of either party to this Agreement to exercise any right, remedy, power or
privilege under this Agreement shall operate as a waiver thereof, nor shall any
single or partial exercise of any right, remedy, power or privilege preclude any
other or further exercise of the same or of any other right, remedy, power or
privilege, nor shall any waiver of any right, remedy, power or privilege with
respect to any occurrence be construed as a waiver of any such right, remedy,
power or privilege with respect to any other occurrence. No waiver shall be
effective unless it is in writing and is signed by the party asserted to have
granted such waiver.

                  (h) Interpretation. No provision of this Agreement is to be
interpreted for or against either party because that party or that party's legal
representative or counsel drafted such provision.

counted, including Saturdays, Sundays and holidays; provided, however, that if
the final day of any time period provided in this Agreement shall end on a
Saturday, Sunday or legal holiday, then the final day shall extend to 5:00 p.m.
of the next full business day. For the purposes of this Section, the term
"holiday" shall mean a day other than a Saturday or Sunday on which banks in the
state in which the Property is located are or may elect to be closed.

and void and neither party shall have any further rights or obligations under
