ITEM 1.  DESCRIPTION OF BUSINESS

BACKGROUND


     SpaceDev, Inc., consisting of one wholly owned subsidiary and one Division,
is a development-stage company organized under the laws of the State of Colorado
on December 23, 1996. It became a publicly traded company in October 1997 and is
currently trading on the Over-The-Counter Bulletin Board exchange under the
symbol "SPDV."

     SpaceDev's overall vision is to establish itself as the world's first
commercial space exploration and development company operating in "small space"
- - small spacecraft, small space transportation systems and focused, low-cost
mission solutions. SpaceDev believes it is pioneering a revolutionary
space-products business that has strong parallels to the early days of the
microcomputer revolution. The Company's approach is to provide small spacecraft
- - approximately 250 kg mass and less - and compatible small space transportation
vehicles to a growing market of commercial and government customers. SpaceDev
intends to use common commercial business practices, whenever possible, rather
than the government-driven processes that dominate the space industry. SpaceDev
seeks to avoid "re-inventing the wheel" on each project and instead intends to
rely on proven, "trailing-edge" technologies used in new ways, and relatively
innovative stable product and service offerings.

     Since its inception, a specific SpaceDev objective has been to be the first
company to successfully define, implement and execute commercial, low-cost
deep-space missions, i.e., missions to the Moon and beyond. All prior deep-space
missions to date - U.S. and foreign - have been government-defined and
relatively expensive. However, following trends from the space
telecommunications sector that began decades ago and more recently in the space
remote-sensing sector, commercial practices have begun to penetrate the
deep-space sector - already a multi-billion-dollar market worldwide. As these
commercial practices take hold and the results of NASA's "faster, better,
cheaper" initiatives bear fruit, total mission costs should decrease.

     SpaceDev's first entrant in this new arena, the Near Earth Asteroid
Prospector (NEAP) mission, was announced in 1997. The Company began offering
commercial Mars and lunar missions in 1999. Since then, the Company has been
actively marketing these missions as enabling products that could provide unique
information content to selected Internet, media, entertainment and education
markets.

     From the outset, the Company's strategy has been to rapidly build a
growing, horizontally integrated company that provides low-cost access to space
through profitable, fixed-price commercial sales. This buildup is fueled by
in-house growth and by strategic acquisitions. Selected space-business niches
will be targeted for acquisition and integration.

     A prime element of this strategy is a strong focus on small, capable,
low-cost satellites and launch systems addressing the deep space and
Earth-orbiting markets. Small satellites are also a key element of low-cost
Earth-orbiting missions, for which demand is rising. Analogous to the computer
field, such small satellites are often called "microsatellites" or
"micro-spacecraft," with their associated "micromissions."

     Another key aspect of SpaceDev's strategy is the hiring of individuals with
world-class experience and skills in the areas above, combined with strategic
acquisitions of companies successfully engaged in these markets. The Company
intends to gain maximum competitive advantage by developing and offering a
limited yet relevant suite of proprietary, open-standard small satellites,
launch systems and related subsystem components. This is how the Company intends
to avoid re-inventing the wheel on each project.

                                       4

THE COMPANY

     In February 1998, the Company acquired Integrated Space Systems (ISS, in
San Diego) ISS is now a wholly owned SpaceDev subsidiary. Most ISS employees are
former launch-vehicle engineers and managers who worked for General Dynamics in
San Diego. At ISS they perform aerospace-engineering services and R&D, with a
principal focus on launch-system and propulsion-module products. In August 1998
SpaceDev also acquired the patents and intellectual property produced by the
former American Rocket Company (AMROC), which specialized in hybrid rocket
technology (solid fuel and liquid or gas oxidizer) for small sounding rockets
and launch vehicles.

     In October 1998 the Company entered into an agreement with Space
Innovations Limited (SIL) in Newbury, England to acquire all of the shares of
SIL in exchange for shares of SpaceDev. By mutual and amicable agreement of both
parties, this transaction was rescinded in December 1999. The primary reason for
the rescission was the difficulties that SpaceDev and SIL encountered in working
with each other due to the new highly restrictive technology-transfer
regulations instituted by the United States.


     Commercial space missions are defined and offered by SpaceDev's Space
Missions Division, with support from ISS, and selected outside partner
organizations. In August 1998 SpaceDev hired two experts in the field of
low-cost spacecraft and space-mission development, Jan King and Rex Ridenoure;
together they form the core technical leadership of this Division.

     With the acquisition of ISS, SpaceDev's employee base increased to 20
employees in February 1998. This number is expected to increase to approximately
40 over the next 12 months. The Company is actively investigating further
strategic acquisitions.

     By 1998 the core SpaceDev team had refined the definition of the NEAP
mission to the degree that NASA formally recognized it as a "Mission of
Opportunity." Established scientists and engineers then began supporting the
concept with scientific-investigation proposals to NASA and commitments from
their home institutions, including three letters of intent for the design and
fabrication of science instruments. In late 1998 SpaceDev began the
approximately two-year process of working with NASA's Jet Propulsion Laboratory
(JPL) to secure scarce Deep Space Network (DSN) tracking time for the mission.
By the summer of 1999, JPL and NASA Headquarters formally agreed that NASA was
prepared to support the NEAP mission with the DSN. A firm contract for a ride on
NEAP was signed with a payload sponsor in mid-1999. Launch was planned for late
2001, with a rendezvous at the near-Earth asteroid Nereus in mid-2002. Multiple
back-up targets are available, if the mission schedule is required to slip. Due
to the number of factors involved and the Company's need for funding, there can
be no assurance that NEAP will be launched.

     Also in late 1998, SpaceDev began bidding on and winning
government-sponsored R&D contracts directly relevant to its strategic interests.
The Company competed with seven other industry teams to perform a mission and
spacecraft feasibility assessment study of proposed 200-kg Mars micromissions
and was one of five firms selected by JPL. The final report was delivered to JPL
in March 1999. A few months later JPL initiated a procurement action for at
least one such spacecraft, to be launched in 2003. For several reasons, the
Company decided not to compete for this NASA contract, but has continued
refining its baseline micromissions concept independent of NASA and JPL, and is
now offering lunar and Mars commercial deep-space missions based on this design.

                                       5
<PAGE>

     In mid-1999 SpaceDev's ISS subsidiary competitively won an R&D contract
from the U.S. Air Force Office of Space Launch to study a family of very small,
hybrid-based "micro" kick-motors for small-satellite orbital transfer
applications. At about the same time, ISS and Lockheed Martin Astronautics (LMA)
entered into a joint marketing agreement to sell packaged commercial launch
services involving two to four small satellites on LMA's Athena launch vehicle.

     In November 1999 the Space Missions Division was awarded a $4,995,868
million turnkey mission contract by the Space Sciences Laboratory (SSL) at
University of California, Berkeley (UCB). SpaceDev was competitively selected by
UCB/SSL to design, build, integrate, test and operate a small scientific,
Earth-orbiting spacecraft called CHIPSat.

     Also in November 1999 SpaceDev hired Charles Lloyd, a leader in the
commercial launch systems field, to be CEO of ISS and CFO for SpaceDev. Mr.
Lloyd brings to the Company extensive experience in corporate finance and
strategic planning as well as direct, recent experience with the development and
implementation of a global marketing and sales organization for commercial
launch systems.

BUSINESS PLAN

     SpaceDev's corporate goal is to increase the intrinsic value of the Company
by providing proprietary, reliable, low-cost access to space through innovative
solutions currently lacking in the marketplace. The Space Missions Division
intends to define and market proprietary, open standards-based, low-cost
space-mission solutions involving microsatellites and nanosatellites. ISS
continues to market its current products and services to the aerospace industry
as well as expand its offerings. SpaceDev intends to continue developing new
products and services the Company's management believes are needed in the
marketplace.

      SpaceDev is successfully implementing a strategic thrust to be perceived
and regarded as an experienced provider of small-satellite launch-integration
services. Its staff and some carefully selected external partners have a
combined experience base with such systems - direct experience in defining,
implementing and operating several dozen small-spacecraft missions - believed to
be equal to any in the industry. This allows the Company to identify launch
opportunities (whether on U.S. or foreign launchers), conceive and evaluate
small-satellite designs matched with those opportunities and to support the
design, development, test, integration, launch and operations of these
satellites.

     SpaceDev believes that a majority of its customers are drawn to the Company
because they are being underserved by the traditional aerospace industry. Most
of the companies that have been servicing this market - especially U.S.
companies - have recently redirected their efforts to larger systems, leaving a
relatively unpopulated market niche for SpaceDev to fill just as the demand for
small satellites is blossoming. The Company intends to continue to introduce new
and useful low-cost space products and services designed to meet customers'
needs, all with an aggressive and practical commercial approach.

     The Company's preferred space-mission implementation approach has the
following attributes atypical of projects done by traditional defense
contractors:

     o    SpaceDev-proprietary spacecraft and launch-vehicle interfaces
     o    SpaceDev-defined products and services from a catalog, rather than
          designs responding to government-supplied specifications
     o    A focus on "Small Space, " involving turnkey mission solutions and
          application of proven commercial business practices such as space
          insurance, competitive pricing and creative billing arrangements
     o    Relatively simple and elegant programmatic and technical solutions

                                       6
<PAGE>

     The Company believes that this business model emphasizing smaller
satellites, commercial approaches, technological simplicity, architectural and
interface standardization and horizontal integration ("whole product") provides
the following advantages:

     o    Enables small-space customers to contract for end-to-end mission
          solutions, reducing the need for and complexity of finding other
          contractors for different project tasks
     o    Creates an easy and convenient way for customers to contract for space
          missions and/or spacecraft subsystems
     o    Lowers total project costs and therefore provides greater value and
          increases return on investment for SpaceDev and its customers
     o    Creates barriers to entry and competition from competitors

     Though the Company prefers to define and execute complete space missions
for clients, it also offers customers space-delivery services (for
customer-supplied science or technology demonstration payloads);
science-instrument or technology-demonstration data-set products (from
SpaceDev-supplied payloads); integration and launch services (for a
customer-supplied spacecraft); and space hardware from commercial price lists
(for customer spacecraft).

     These features of the Company's business approach thus place it more into
the template that existed during the early days of the microcomputer revolution
rather than into the classical patterns of the existing government-dominated,
limited-profit margin, aerospace industry.

PRODUCTS AND SERVICES

     SpaceDev's products and services are grouped into three business areas:
Space Missions, Space Products and Engineering Services. Its business is not
seasonal to any significant extent; however, because it is a commercial
business, it follows normal industry trends.

     SPACE MISSIONS

     The Company's Space Missions Division offers commercial, standards-based
turnkey space missions for sale as products to a variety of customer bases
(government agencies, other countries, universities, corporations, consortia,
individuals, etc.). It is this product line for which SpaceDev was originally
formed, particularly in the deep-space arena.

     DEEP-SPACE MISSIONS. SpaceDev defined the NEAP mission in 1997-99 and has
been in the process of taking the necessary steps for project implementation. In
1998 NASA Headquarters recognized the project as a valid commercial "Mission of
Opportunity" for both its Discovery Program of solar-system exploration missions
and Mid-class Explorer ("MIDEX") program of space-science missions. This opened
the door for space scientists to submit proposals to NASA for science-instrument
development funding and for coverage of the fee that SpaceDev would charge the
scientist for an instrument ride on NEAP. Three proposals were submitted (two to
Discovery and one to MIDEX) in 1998, but none were selected nor funded. In
December 1998, SpaceDev funded JPL to evaluate the feasibility of supporting the
NEAP mission with NASA's DSN, and in October 1999 JPL and NASA headquarters
concurred that such support was feasible. From the mission-operations
standpoint, NASA now treats NEAP as a valid mission (an "Advanced Planning"
mission). NEAP is the first proposed commercial deep-space mission to be granted
this status.

                                       7
<PAGE>

     In December 1998, approximately fifteen months after SpaceDev announced the
feasibility of deep space missions costing less than $50 million, a SpaceDev-led
team was awarded a contract by JPL to assess the feasibility of sending
"micromissions" to Mars for less than $50M total mission cost each. These
missions would cost approximately one-third to one-fifth of recent Mars-mission
costs. An extensive final report was submitted to JPL the following March. This
work formed the basis for redefining the NEAP mission to be significantly
smaller and lower cost than the previous baseline and also prompted SpaceDev to
offer low-cost commercial lunar orbiter and Mars probe-carrier missions
employing a similar design. The Company marketed its commercial micromissions
concept during the summer of 1999 and by late fall was fielding inquiries from
various U.S. and foreign prospects.

     EARTH-ORBITING MISSIONS. A natural byproduct of the Company's focus on
small, low-cost spacecraft for commercial deep-space mission applications is the
in-house capability to design, build, market and sell similar concepts for
Earth-orbiting applications.

     In November 1999 the Space Missions Division was awarded a turnkey mission
contract by the Space Sciences Laboratory (SSL) at University of California,
Berkeley (UCB). SpaceDev was competitively selected by UCB/SSL's Dr. Michael
Hurwitz to design, build, integrate, test and operate a small spacecraft called
CHIPSat. The 85-kg microspacecraft will carry one science instrument, the Cosmic
Hot Interstellar Plasma Spectrometer, or CHIPS. CHIPS facilitates the
observation and diagnosis of the astrophysical environment in the void outside
our solar system and between the nearby stars in our galaxy. Dr. Hurwitz, the
CHIPS Principal Investigator, and his team are responsible for the overall
CHIPSat mission, designing and building the CHIPS instrument, and performing the
science-data analysis.

     CHIPSat is the first mission of NASA's low-cost University-Class Explorer
(UNEX) series to be approved for the implementation phase. SpaceDev started its
work on the CHIPSat project in November 1999 under the $4,995,868 million
commercial, fixed-price contract with UCB. Initial integration and testing of
the spacecraft's components are planned at the Company's headquarters in Poway
in late 2000. Launch at the Cape Canaveral Air Station on a Boeing Delta II is
expected in early 2002, followed by one year of mission operations to be
controlled at SpaceDev's Mission Control Center in Poway, California.

     SpaceDev believes that the CHIPSat contract establishes the Company as a
significant competitor in the small-satellite arena, and it expects this
perception to spread rapidly among NASA, DoD, university/R&D, and foreign and
commercial customer bases during the next several months.

     SPACE PRODUCTS

     SpaceDev's space-products business currently includes spacecraft and
related space systems; launch vehicles and propulsion modules.

       SPACECRAFT AND RELATED SPACE SYSTEMS. The Company is presently bidding on
several programs to supply spacecraft buses that would utilize the basic
elements of the CHIPSat and other proprietary spacecraft designs.

     LAUNCH VEHICLES AND PROPULSION MODULES. Currently, SpaceDev's ISS
subsidiary is performing design analyses and computer simulations of various
sounding rockets and launch vehicles that primarily use hybrid-propulsion
technology (based on the AMROC intellectual property). The Company anticipates
the possible spin-off of this activity from ISS once specific product lines are
defined and developed. Currently, however, no action has been taken to
accomplish such a spin-off.

     In mid-1999 ISS competitively won an R&D contract from the U.S. Air Force
Office of Space Launch to study the feasibility of building small, hybrid-based
"micro" kick-motors for small-satellite applications. The Secondary Payload
Orbital Transfer Vehicle (SPOTV) family has a multitude of possible on-orbit
uses and is now being marketed by SpaceDev as a part of its growing product
line.

                                       8

     ENGINEERING SERVICES

     SpaceDev corporate-level staff and staff in SMD and ISS are available for
supplying aerospace-related technical services to a variety of clients. ISS is
currently most actively engaged in such services.

     Most ISS employees are former launch systems engineers and managers at
General Dynamics in San Diego; many have extensive experience with the Atlas
family of launch vehicles and other large-scale rockets and launch facilities.
The ISS staff has core competencies in engineering design and analysis; system
modeling and simulation; instrumentation and testing; launch-site operations and
range safety; launch environments and transport; and mission and trajectory
design. Other skills include project planning and development; systems
engineering and pre-design engineering (e.g., definition of engineering
processes and methods); and systems integration.

     ISS has recently performed launch-vehicle design and testing support
services for the Atlas launcher program, Titan/Centaur program and the Kistler
Aerospace launcher development program. ISS has also provided launch-site
design, analysis, test and operations support for various U.S. launcher programs
and launch sites. Various engineering services have been supplied to over a
dozen unmanned spacecraft, manned spacecraft and Remotely Piloted Vehicles
(RPVs).

MARKET STRATEGIES

     SPACE MISSIONS

     The Company intends through its commercial deep-space and Earth-orbiting
missions to prove its viability and establish itself as the premier commercial
space-exploration and development company. Once it has established its
capabilities for insured, high-quality, fast turnaround and low-cost systems and
missions, the Company believes it will be able to effectively compete, develop
new markets and expand existing markets for space exploration and other
applications.

     The Company believes that its low-cost commercial missions can provide
unique information content to various traditionally unconventional space-mission
customers. In particular, the Company is actively seeking potential strategic
partners and customers who share SpaceDev's vision of the convergence of
commercial deep-space activities with selected Internet, media, entertainment
and education activities.

     DEEP-SPACE MISSIONS. Since all deep-space missions to date world-wide have
been defined and executed by various government agencies, SpaceDev's plan for
defining and executing such missions as a commercial venture places the Company
at the forefront of a new way of doing business in this arena. Under such
conditions, questions naturally arise within the space community about whether
the Company and its partners are capable of successfully performing in this
arena. The Company's approach is two-fold: (1) Selectively compete for
deep-space related work (R&D studies and development efforts as well as real
projects) against established space-systems companies, and (2) Define, develop
and execute space missions independently of government agencies. Inherent to the
latter approach is a concerted effort to define and cultivate alternative
sponsors for these missions, such as other commercial companies, research and
technology consortia, non-U.S. space interests, etc.

     SpaceDev's win of the JPL-funded Mars Micromissions study in 1998 is
representative of approach (1) above, while its efforts to define and promote
the NEAP mission fit approach (2) above.

                                       9
<PAGE>

     EARTH-ORBITING MISSIONS. The market situation in this arena has
similarities to the deep-space arena, but there are more competitors and a wider
variety and greater number of missions to consider as marketing targets. The
challenge here, as in the deep-space arena, is for the Company to rapidly
establish credibility by selectively competing for and winning R&D studies and
development efforts as well as real projects. The Company's commercial focus
works more easily with government-funded efforts if it performs the work on a
commercial basis for a Principal Investigator or task manager who interfaces
directly with the government sponsor(s). For non-governmental sponsors, the
Company prefers to deal directly with the customer(s).

     SPACE PRODUCTS

       SPACECRAFT AND RELATED SPACE SYSTEMS. In general, the Company believes
that any market target in the space-missions segment discussed above also
represents a potential customer for its space products (vs. turnkey missions).
This includes both the earth-orbiting and deep space markets.

     LAUNCH VEHICLES AND PROPULSION MODULES. SpaceDev addresses this market
segment with its ISS subsidiary. Small spacecraft are produced by government
agencies, universities and commercial companies throughout the United States,
Europe and Japan. These spacecraft represent significant science and
technology-demonstration opportunities that require exposure to the space
environment to fulfill their mission objectives. Annual launch rates for such
spacecraft are limited principally by the high cost of current launch vehicles.
These conditions result in many valuable experiments and payloads being left on
the ground.

     Recognizing this problem, government and commercial industry have been
performing research and development in an attempt to reduce the cost per
kilogram (or pound) to orbit for small spacecraft. Paul Coleman, president of
the Universities Space Research Association (USRA), has challenged the space
industry with launch-cost targets priced between $2.0M and $3.5M for a 300-kg
spacecraft. Clearly, today's commonly used launch-vehicle technologies cannot
achieve this goal. Launch service users have pinned their future hopes on
reusable launch vehicles, which appear to be ten years or more away from
day-to-day use, to lower launch costs.

     In the near term the only real hope for small spacecraft is to find an
alternative path to space using a secondary ride system such as the Ariane
Structure for Auxiliary Payloads (ASAP) or a low-cost launch system yet to be
developed. ISS retained key personnel critical in the development of General
Dynamics' Atlas Centaur launch vehicle. It is believed that this level of
experience has never before been available to the small launch-vehicle market.
ISS has also obtained the rights to the patents and intellectual property
produced by the former American Rocket Company (AMROC), which specialized in
hybrid rocket technology (solid fuel and liquid or gas oxidizer) in the design
of sounding rockets and launch vehicles.

     The ISS approach of combining large-vehicle expertise with the lower cost
inherent in hybrid rocket technology could give small payload customers new and
valuable capabilities at small-business savings. SpaceDev research has indicated
a very large university and government market, starving for cost-effective
access to space. ISS intends to put that expertise to work building a family of
orbital transfer vehicles and small launch vehicles using hybrid rocket
technology. The funds need to fully develop this family of vehicles have not yet
been secured and there is no guarantee that these funds can be raised.

     ENGINEERING SERVICES

     SpaceDev addresses this market segment principally with its ISS subsidiary,
though the SMD staff can be applied selectively to provide such services. The
current business base lies principally within the aerospace- engineering and
test-services market. ISS can be distinguished from its competitors by its
highly experienced personnel, who gained their knowledge and know-how during
years of employment with major aerospace companies (General Dynamics Space
Systems in particular). Contemporary space-market analysis indicates an overall
trend toward shrinking budgets. This could result in smaller spacecraft, rapid
turn-ons, shorter schedules and smaller project budgets. ISS is being groomed to
work within this environment. ISS intends to exploit its technologies, low-cost
focus, rapid turn-on capabilities and small-business assets to form teaming
arrangements, solicit business and win contracts.

     Currently no experienced small launch-vehicle company is known to offer
this service to space-vehicle contractors. ISS also offers experienced personnel
to launch-vehicle customers as a low-cost alternative to in-house capabilities.
ISS provides companies the ability to complete jobs where the work has surpassed
workforce capabilities or the task requires unique expertise, without having to
hire permanent employees.

COMPETITION

     SpaceDev believes that competition for sales of its products and services
is based on price, performance and other technical features, contracting
approach, reliability, scheduling, customization, and in some situations,
geography.

     SPACE MISSIONS

     The primary domestic competition for space missions in the targeted
SpaceDev markets comes from such companies as Orbital Sciences Corporation, Ball
Aerospace and Technology Corporation, Spectrum Astro, Inc., Space Dynamics
Laboratory and AeroAstro. Though Lockheed Martin Aerospace, TRW, Inc., Swales
Aerospace, GM Hughes Electronics and a few other companies and R&D organizations
are perhaps capable of mounting a competition in these markets, the Company is
not aware of any serious intent to do so. SpaceDev believes that it has made
much more substantial and significant progress compared to these firms in
defining business models and pursuing sales in the small, emerging commercial
deep-space and Earth-orbiting markets. In addition to private companies there
are certain universities in the United States that have the capability to
produce reasonably simple satellites.

     The clear competitor in the international arena is Surrey Satellite
Technology Limited in the UK. Swedish Space Corporation is also able to compete
in the small-satellite arena; they were named in November 1999 as the prime
contractor for ESA's SMART-1 technology-demonstration spacecraft to the Moon.

     The Company is not aware of any current direct and credible competition in
the field of commercial space exploration and development. Firms such as those
mentioned above and other R&D laboratories (e.g., JPL, Applied Physics
Laboratory, ISAS in Japan) have the technical knowledge and experience to design
and execute missions similar to NEAP and CHIPSat, but they are primarily
government agencies or contractors. SpaceDev management believes that federal
procurement regulations and accounting systems make it difficult if not
impossible for these companies and labs to compete on price with the Company.

     Governments and government programs like those in NASA, ESA and the
Japanese space agencies (NASDA and ISAS) have executed many missions over a
period of many years, but all of these are characterized by long lead times,
high expense, little flexibility, and generally uninsured payloads. It is
SpaceDev's opinion that NASA Administrator Dan Goldin has done an excellent job
in lowering the cost of NASA missions, but the cost has declined from billions
of dollars to hundreds of millions of dollars, whereas SpaceDev is targeting
missions costing tens of millions. With the overhead and culture of such
agencies and their defense contractors, it may be difficult for the
government-defined and managed programs to lower costs much more.

     The Company believes that government-driven programs pose very little
threat of competing on the basis of price, although governments have
considerably greater experience, and substantially greater financial, workforce
and facilities resources. The Company also believes that governments and their
legislatures will increasingly encourage and support private, routine commercial
space exploration due to budgetary pressures, private-sector job creation and
tax-revenue considerations.

                                       11

     SPACE PRODUCTS

     The trend in some sectors of the space industry to smaller, lower cost
spacecraft is creating a new market for smaller, cheaper, launch-on-demand space
systems. With respect to SpaceDev's initiatives into low-cost launch systems,
several competitors have already entered the top end of this small-satellite
market, including Lockheed Martin with its Athena launch vehicle and Orbital
Sciences Corporation with its Pegasus and Taurus. The launch costs of these
vehicles, beginning at approximately $16 million per launch, are considered by
many to be too expensive for university-class and micro-spacecraft missions,
resulting in low launch rates for these launch systems. Although these companies
have been operating longer than SpaceDev, the Company believes that it may be
able to effectively compete against them in the area of launching small
satellites for under $10 million. This, combined with what is perceived as the
rapid growth in the demand for mini and micro-satellites, has left the market
open for a low-cost, reliable, rapidly deployed family of launch vehicles.

      EXPENDABLE LAUNCH VEHICLES. Today's launch mainstays in the large
launch-vehicle class are the United States' Titan, European Ariane and Russian
Proton and Zenit. In the medium launch-vehicle class the United States' Atlas
and Delta rockets face heavy competition from around the world from the European
Space Agency, former Soviet States and more recently from Japan, China and
India. In the small launch-vehicle class the United States' Athena, Taurus and
Pegasus are dominant. Microcosm, Inc. has been working on the development of a
low-cost family of expendables called Scorpius, with first orbital launch not
expected before 2002. A common thread in the existing medium and small
launch-vehicle classes is that the United States' launch systems are
consistently more expensive than their foreign counterparts. SpaceDev believes
there is a great need for a low-cost (less than $10 million) U.S.-built and
controlled micro launch system. SpaceDev has not formally initiated a launch
vehicle program and might not in the future.

     RE-USABLE LAUNCH VEHICLES. There is only one partially re-usable launch
vehicle currently in use: the Space Shuttle (the "Space Transportation System,"
or STS). Over the past five years, a multitude of companies have been working on
a variety of designs to capture this market. The most notable attempts at
developing re-usable vehicles are the NASA co-sponsored X-33/Venture Star (with
a Lockheed Martin-led consortium), the X-34 (with an Orbital-led consortium) and
the X-38 (led by Boeing). Other commercial firms such as Kistler, Kelly, Roton,
and Pioneer Rocketplane are attempting to develop conceptually similar systems.

     ENGINEERING SERVICES

     There are a number of small to very large companies that supply engineering
services in the space arena. SpaceDev offers one unique capability in that it
has collocated in one area both launch and spacecraft engineers. This allows the
Company to provide efficient and coordinated responses to design issues that
almost always have both spacecraft and launch considerations.

REGULATION

     The Company's business activities are regulated by various agencies and
departments of the U.S. Government and, in certain circumstances, the
governments of other countries. Exports of the Company's products, services, and
technical information require licenses from the U.S. Department of State, which
recently published new regulations restricting the ability of U.S. based
companies to complete off-shore launches, or to export certain satellite
components and technical data to certain non-NATO countries. Commercial space
launches require licenses from the U.S. Department of Transportation.

                                       12
<PAGE>

     Command and telemetry frequency assignments for space missions are
regulated internationally by the International Telecommunications Union (ITU)
and in the U.S. by the Federal Communications Commission (FCC) and National
Telecommunications Information Agency (NTIA).

     In addition, the Company is required to obtain permits, licenses, and other
authorizations under federal, state, local and foreign statutes, laws or
regulations or other governmental restrictions relating to the environment or to
emissions, discharges or releases of pollutants, contaminants, petroleum or
petroleum products, chemicals or industrial, toxic or hazardous substances or
wastes into the environment including, without limitation, ambient air, surface
water, ground water, or land, or otherwise relating to the manufacture,
processing, distribution, use, treatment, storage, disposal, transport or
handling of pollutants, contaminants, petroleum or petroleum products, chemicals
or industrial, toxic or hazardous substances or wastes or the clean-up or other
remediation thereof.

     The failure of the Company to comply with any of the above mentioned
regulations could have material adverse effects.

EMPLOYEES

     As of the date of this registration statement, the Company, together with
ISS, employs approximately 25 persons full and part-time, of which most are
aerospace, mechanical and electrical engineers. The Company expects to hire
other personnel as necessary for product development, quality assurance, sales
and marketing and administration.

     SpaceDev does not have any collective bargaining agreements with its
employees and believes its employee relations are good. An employee
stock-incentive program and an employee stock-purchase program were approved at
the 1999 annual shareholders meeting and have been implemented.

INTELLECTUAL PROPERTY

     SpaceDev relies in part on patents, trade secrets and know-how to develop
and maintain its competitive position and technological advantage. The Company
intends to protect its intellectual property through a combination of license
agreements, trademark, servicemark, copyright, trade secret laws and other
methods of restricting disclosure and transferring title. There is no guarantee
that such applications will be granted. The Company has and intends to continue
entering into confidentiality agreements with its employees, consultants and
vendors; entering into license agreements with third parties; and generally
seeking to control access to and distribution of its intellectual property.

     In August 1998, SpaceDev acquired license to intellectual property
(including patents and trade secrets) from an individual who had acquired them
from the former American Rocket Company (AMROC), which specialized in hybrid
rocket technology. The Company issued warrants to this individual to purchase a
minimum of 100,000 and a maximum of 3,000,000 shares of its Common Stock over
the next 10 years, depending on the Company's annual revenues related to sales
of hybrid technology-based products.

     In 1999 the Company began preparing a new patent application addressing a
technological need in the small-satellite arena. It expects to submit the
application in early 2000.

OVERVIEW

     SpaceDev, Inc. is a development-stage company organized under the laws of
the State of Colorado on December 23, 1996. It became a publicly traded company
in October 1997 and is currently trading on the Over-The-Counter Bulletin Board
exchange under the symbol "SPDV."

     SpaceDev's overall vision is to establish itself as the world's first
commercial space exploration and development company operating in "small space"
- - small spacecraft, small space transportation systems and focused, low-cost
mission solutions. SpaceDev is pioneering a revolutionary space-products
business that has strong parallels to the early days of the microcomputer
revolution. The Company's approach is to provide small spacecraft -
approximately 250 kg mass and less - and compatible small launch vehicles to a
growing market of commercial and government customers. SpaceDev intends to use
common commercial business practices rather than the government-driven processes
that dominate the space industry. SpaceDev seeks to avoid "re-inventing the
wheel" on each project and instead intend to rely on proven, "trailing-edge"
technologies and relatively stable product and service offerings.

     During 1997 operating activities consisted largely of developing the
preliminary designs and mission analysis for the NEAP mission. During 1998,
SpaceDev acquired ISS and SIL. In 1998, operating activities included
engineering technical services work for aerospace customers and continued
development of NEAP preliminary designs and mission analysis. During 1999,
operating activities included preliminary design and conceptual studies for the
CHIPSat program, engineering technical services and continued work on the NEAP
mission. SpaceDev's employee base increased with the acquisition of ISS to 20
employees in February 1998.

      Effective December 17, 1999, SpaceDev. Inc. entered a "Mutual Release and
Rescission of Agreement" with the management of Space Innovations Limited (SIL)
to rescind the original acquisition of SIL by SpaceDev. Following general
acceptable accounting principles, SpaceDev Inc.'s 1998 Consolidated Financial
Statements have not been restated and include SIL as a wholly-owned subsidiary.
All interim financial statements for 1999 have been adjusted and will include
SIL under the equity method of accounting, as a consolidated entity since
control of SIL was only temporary. Goodwill related to the acquisition of SIL
was reclassified to investment in SIL and not eliminated on the consolidated
financial statements for 1999.

RESULTS OF OPERATIONS FOR THE FOUR-MONTH PERIOD ENDED DECEMBER 31, 1997 AND THE
FISCAL YEAR ENDED DECEMBER 31, 1998

         NET SALES

         For the four-month period ended December 31, 1997 the Company generated
no sales. In 1998, net sales consisted primarily of engineering technical
services to aerospace customers. Net sales were $2,093,254 in 1998.

         COST OF SALES

         Cost of sales primarily represents all costs directly associated with
individual contracts. Included in this category are direct labor and associated
fringe benefits, direct material and subcontracts, and direct travel. Cost of
sales was $1,152,813 (55.1% of net sales) for 1998 compared to no cost of sales
generated for 1997.


                                       14
<PAGE>


         SALES AND MARKETING

         The Company did not incur sales and marketing expenses for the period
ended December 31, 1997. Sales and marketing expense consists primarily of
direct marketing expenses, salaries and commissions. Sales and marketing expense
was $141,581 (6.8% of net sales) during 1998.

         RESEARCH AND DEVELOPMENT

         Research and development expense in 1998 was $700,921 compared to
$904,094 expended in 1997. The 1998 expense was incurred in the continued
development of the NEAP project and SIL's program to develop their MiniSIL and
small satellite projects. The 1997 expenses were primarily subcontractor and
consulting expenses related to the NEAP project. The Company expenses research
and development costs as they are incurred.

         GENERAL AND ADMINISTRATIVE

         General and administrative expense consist primarily of salaries for
administrative personnel, fees for outside consultants, goodwill allocation of
acquisition costs, depreciation, facilities related costs, insurance, legal and
accounting fees, and other overhead. General and administrative expense was
$2,001,507 (95.6% of net sales) during 1998 compared with no general and
administrative expenses for 1997. Amortization expenses associated with the
acquisition of ISS, SIL and the hybrid technology totaled $894,688 (44.7% of
total general and administrative). It is anticipated that overall general and
administrative expense will increase in the foreseeable future. General and
administrative expense as a percentage of net sales may fluctuate depending upon
the level of future net sales and the timing of additional investments in
general and administrative infrastructure.

         OTHER INCOME EXPENSE, (NET)

         Net interest expense of $6,074 during 1998 resulted from interest
incurred on a building mortgage and various leases of $87,270 and other income
of $93,154 from SIL's Grant contract with the UK government. The Company did not
incur interest expenses for the period ended 1997.

RESULTS OF OPERATIONS FOR NINE MONTHS ENDED SEPTEMBER 30, 1999

         NET SALES

         Net sales, for the nine months ended September 30, 1999, consisted
primarily of the sales for engineering technical services to various aerospace
customers. Net sales were $634,145 for the nine months ending September 30, 1999
compared with sales of $1,083,096 for the same period in 1998 (41.5% reduction).
This reduction in sales was a direct result of Integrated Space Systems' move
from the Small Disadvantage Business classification after being acquired. This
reclassification resulted in loss contract opportunities of approximately
$500,000. However, during this period, contracts with seven new customers were
initiated.

         Net sales are generated through either fixed price contracts or time
and material contracts. Sales recognition for time and material contracts is
recognized at time of work, while fixed price contracts are based on a percent
completion basis.

         On November 1, 1999, SpaceDev entered into a $4,995,868 firm fixed
price contract with the University of California at Berkeley. It is anticipated
that net revenues will increase in the year 2000 with this contract award.

                                       15
<PAGE>

         COST OF SALES

         Cost of sales primarily represents all costs directly associated with
individual contracts. Included in this category are direct labor and associated
fringe benefits, direct material and subcontracts, and direct travel. Cost of
sales for the nine-month period ended September 30, 1999 was $331,498 (52.3% of
net sales) compared to $493,268 (46% of net sales) for the first nine months of
1998.

         RESEARCH AND DEVELOPMENT

         Research and development expense for the nine-month period ended
September 30, 1999 was $67,816 compared to $173,754 for the first nine months in
1998 (61.0% reduction). These expenses were incurred in the continued
development of the NEAP project and other projects. The Company expenses
research and development costs as they are incurred.

         GENERAL AND ADMINISTRATIVE

         General and administrative expense consists primarily of salaries for
administrative personnel, fees for outside consultants, goodwill allocation of
acquisition costs, depreciation, facilities related costs, insurance, legal and
accounting fees, and other overhead. General and administrative expense for the
nine months ended September 30, 1999 was $1,896,045 (299% of net sales) compared
to $1,314,325 (121% of net sales) during first nine months of 1998. Amortization
expenses associated with the acquisition of Integrated Space Systems for the
nine months ending September 30, 1999 totaled $522,826 (24.3% of general and
administrative) compared to $462,078 in the same period in 1998 (35% of general
and administrative). SpaceDev anticipates that overall general and
administrative expense will increase in the foreseeable future; however, general
and administrative expense as a percentage of net sales may fluctuate depending
on the level of future net sales and the timing of additional investments in
general and administrative infrastructure.

         OTHER INCOME EXPENSE, (NET)

         Net interest expense of $500,541 for the nine-month period ended
September 30, 1999 was interest incurred on a building mortgage and various
leases of $220,680 and an equity loss in subsidiary of $280,127.

LIQUIDITY AND CAPITAL RESOURCES

     The Company's business strategy requires significant capital expenditures.
The Company will incur a substantial portion of these expenditures before it
generates significant sales. Combined with operating expenses, these capital
expenditures will result in a negative cash flow until the Company establishes
an adequate revenue-generating customer base. The Company expects losses through
2000 and does not expect to generate net positive cash flow from operations
sufficient to fund both operations and capital expenditures until the launch of
its first commercial spacecraft or launch vehicle. There is no assurance that
the Company will achieve or sustain any positive cash flow or profitability
thereafter.

     During the year ended December 31, 1999, the Company raised approximately
$900,000 through private sales of stock. After consummation of this offering,
the Company still requires substantial additional funds, currently estimated at
more than of $10,000,000 to implement its business strategies. The Company does
not have a commitment from any placement agent or underwriter to obtain
additional funds or to implement this or any additional public offering. The
Company hopes to raise additional capital through private or public offerings.
The expected proceeds from such offerings are expected to generate sufficient
funds to meet the Company's cash requirements for the next twelve months and to
allow the Company to begin to implement various business strategies. The Company
has raised $360,000 of funding through a recent registered offering in Colorado,
and anticipates that such capital, when coupled with revenues generated by
CHIPSat and the Company's general operations, may be sufficient to help maintain
operations until additional funding becomes available.

                                       16
<PAGE>

      The Company's ability to consummate any additional public offering or
otherwise obtain funds is subject to numerous factors beyond the Company's
control, including, without limitation, a receptive securities market and
appropriate governmental clearances. No assurances can be given that the Company
will be profitable, or that any additional public offering will occur, that the
Company will be successful in obtaining additional funds from any source or that
the Company will be successful in implementing an acceptable exit strategy on
behalf of its investors. Moreover, additional funds, if obtainable at all, may
not be available on terms acceptable to the Company when the Company needs such
funds or may be on terms which are significantly adverse to the Company's
current shareholders. The unavailability of funds when needed would have a
material adverse effect on the Company.

       The Company may also need to raise additional capital if, for example,
(i) significant delays occur in deploying its first deep-space mission due to
technical difficulties, launch, or satellite failure, or other reasons; (ii) the
Company does not enter into agreements with customers on the terms the Company
anticipates; (iii) the Company's net operating deficit increases because it
incurs significant unanticipated expenses; or (iv) the Company incurs additional
costs from modifying all or part of NEAP or its proposed hybrid-related systems
to meet changed or unanticipated market, regulatory, or technical requirements.
If these or other events occur, there is no assurance that the Company could
raise additional capital on favorable terms, on a timely basis or at all. A
substantial shortfall in funding would delay or prevent deployment of NEAP
and/or the hybrid-related systems.

RECENT DEVELOPMENTS

       In December 1999 the Company completed negotiations with SIL to rescind
the 1998 Share Acquisition Agreement between the parties and to arrange a more
mutually beneficial trading relationship between SIL and the Company. It was
unclear what effect recent regulations released by the U.S. Department of State
(restricting export of technical information) would have on the offshore
operations of SIL as a wholly owned subsidiary of the Company. Management
believed rescission of the agreement would allow the Company more flexibility in
its relationship with SIL. Although the long-term financial effects of the
rescission on the Company are unclear, management anticipates that, initially,
the rescission will have a positive net effect on the Company's balance sheet.

       In January 2000, the Company received preliminary approval from a
financial institution to refinance the $1.3 million first mortgage on the
company's office building. This refinancing changes the first mortgage from a
one-year term loan to a 25-year term loan and reduces the interest expense from
13% to 10%.

YEAR 2000 COMPLIANCE

     Many existing computer systems and applications, and other control devices
use only two digits to identify a year in the date field, without considering
the impact of the recent change in the century. Others do not correctly process
"leap year" dates. The Company has not experienced any technical difficulties as
a result of this problem, however, systems and applications could fail or create
erroneous results during the next six months. While the Company has evaluated
its products for year 2000 compliance and believes that each is substantially
year 2000 compliant, there can be no assurance that the Company's products are
or will ultimately be year 2000 compliant. In addition, the Company believes
that it is not possible to determine whether all of its customers' products into
which the Company's products are incorporated are year 2000 compliant because
the Company has little or no control over the design production and testing of
its customers' products.

                                       17
<PAGE>

     The Company relies on its systems, applications and devices in operating
and monitoring all major aspects of its business, including financial systems
(such as general ledger, accounts payable and payroll modules), customer
services, infrastructure, embedded computer chips, networks and
telecommunications equipment and end products. The Company could be affected
through disruptions in the operation of the enterprises with which the Company
interacts or from general widespread problems or an economic crisis resulting
from non-compliant year 2000 systems. Despite the Company's efforts to address
the year 2000 impact on its internal systems and business operations, there can
be no assurance that such impact will not result in a material disruption of its
business or have a material adverse effect on the Company's business, financial
condition or results of operations. Contingency plans include alternative
vendors and procedures. Remediation costs associated with the Year 2000 have
been minimal for the Company. SpaceDev believes such costs will continue to be
nominal through the next six months.

ITEM 3.  DESCRIPTION OF PROPERTY

     SpaceDev owns over 25,000 square feet of office, engineering and
manufacturing space in Poway, CA.

     In December 1998 the Company purchased its headquarters facility in the
Poway Industrial Park complex and proceeded to invest $300,000 in modifications
and improvements before moving in mid-May (SpaceDev corporate and ISS). Key uses
of the Poway facility are program and project conferences and meetings,
engineering design, engineering analysis, spacecraft assembly, avionics labs and
software labs and media outreach. By late 1999 the Company had defined plans for
outfitting the building with a 1,800 square foot clean-room facility to support
spacecraft integration and additional space for testing, an avionics test area,
machine shop and shipping/receiving area. Completion of these improvements is
expected in 2000. The Company also has plans for a Mission Control Center in the
Poway building and expects this to be completed in 2000. Avionics systems may be
built up from components and undergo system-level tests at this location prior
to shipment to other facilities. Because these improvements depend on the
Company obtaining adequate funding, there can be no assurance that they will be
completed as scheduled.

ITEM 4.  SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

     The following table provides information as December 31, 1999 concerning
the beneficial ownership of the Company's common stock by (i) each director,
(ii) each named executive officer, (iii) each shareholder known by the Company
to be the beneficial owner of more than 10% of its outstanding Common Stock, and
(iv) the directors and officers as a group. Except as otherwise indicated, the
persons named in the table have sole voting and investing power with respect to
all shares of Common Stock owned by them.

     The following is a summary of the business experience of the officers and
directors of the Company as well as other key employees.

     JAMES W. BENSON, age 54, is the founder of the Company, and has served as
its Chief Executive Officer and President since inception. Mr. Benson is also a
Director of the Company, a position he has held since October 1997. In 1984, Mr.
Benson founded Compusearch Corporation (later renamed Compusearch Software
Systems), in McLean, Virginia. The company was based on use of personal
computers to create full text indexes of massive government procurement
regulations and to provide fast full text searches for any word or phrase; the
first instance of large scale, commercial implementation of PC-based full text
searching, which later grew to encompass such systems as worldwide web search
engines. Seeing related opportunities in document and image management, Mr.
Benson started the award-winning ImageFast Software Systems in 1989, which later
merged with Compusearch. In 1995, Mr. Benson sold Compusearch and ImageFast, and
retired at age fifty. After months of research, Mr. Benson started SpaceDev LLC,
which was acquired by the Company in October 1997. Mr. Benson holds a Bachelor
of Science degree in Geology from the University of Missouri. He founded the
non-profit Space Development Institute and introduced the $5,000 Benson Prize
for Amateur Discovery of Near Earth Objects. He is also Vice-Chairman and
private sector representative on NASA's national Space Grant Review Panel and a
member of the American Society of Civil Engineers subcommittee on Near Earth
Object Impact Prevention and Mitigation.

     CHARLES H. LLOYD, age 49, has been retained as the Company's Chief
Financial Officer following resignation of that position by Thomas W. Brown on
November 3, 1999. Mr. Lloyd has also been named the CEO of the Company's ISS
subsidiary. Mr. Lloyd was formerly the CEO and President of International Launch
Services (ILS), a joint venture of Lockheed Martin Corporation, Khrunichev State
Research and Production Space Center and RSC Energia. During his tenure at ILS,
he was responsible for the development, expansion, and ongoing operation of the
joint venture. Lloyd aggressively marketed product lines globally, not only by
overcoming cultural barriers, but also by structuring the organization to
support multiple product and management requirements. He is credited with
developing strategic international relationships between the United States and
Russia, and with setting the industry standard for strict controls in the
transfer of technology. Lloyd and his team at ILS generated over a billion
dollars in new contracts and developed competitive markets in Asia, Europe, and
North America, all of which have provided increased revenues. Mr. Lloyd has
close to 20 years of senior management experience in high technology,
international service and manufacturing environments, with most of that time in
positions focused on operations management, marketing and finance and
administration. Prior to his employment with Lockheed and ILS, Mr. Lloyd held
several management positions at General Dynamics (GD). He was Vice President and
Managing Director, and responsible for the management and operations of General
Dynamics Commercial Launch Services. Prior to that, he was Vice President of
Finance and Controller of GD Space Systems, and Vice President of Finance and
Administration of GD Services Company. Mr. Lloyd began his career as a Senior
Financial Planning Analyst at Ford Motor Company in 1975. Mr. Lloyd holds a
Masters of Business Administration from the University of Michigan and earned
his Bachelor of Arts Degree in Finance from Virginia Polytechnic Institute and
State University.

     compensation.
(4)  James W. Benson purchased 100,000 shares for $.50 per share in December
     1998.
(5)  Certain of the employees listed above have earned compensation in excess of
     the actual amount paid during fiscal year ended 1999, pursuant to the terms
     of their various employment agreements, as discussed below. In 1999, Philip
     E. Smith was paid a salary of $43,388 and Thomas Brown was paid $68,454.
     These amounts are less than the amounts due to them under the provisions of
     their employment agreements. The Company is currently in negotiations with
     both Mr. Smith and Mr. Brown to determine the actual amount still due to
     them for services provided in 1999 and the form of payment. It is possible
     that all or a portion of the amount due will be paid to Mr. Smith and Mr.
     Brown on a deferred basis or in the form of non-cash consideration. It is
     anticipated that the final results of these negotiations will not have a
     material impact on the Company's financial results.

         During the last fiscal year and as of December 31, 1999, the Company
granted stock options to executive officers as set forth in the following table:

<PAGE>

     VOTING RIGHTS

       Each outstanding share of Common Stock is entitled to one vote. The

they so choose.

     Holders of Common Stock are not entitled to any preemptive rights.

     DIVIDENDS AND DISTRIBUTIONS

     Holders of Common Stock are entitled to receive such dividends as may be
declared by the directors out of funds legally available therefore and to share
pro rata in any distributions to holders of Common Stock upon liquidation or
otherwise. However, the Company has not paid cash dividends on its Common Stock,
and does not expect to pay such dividends in the foreseeable future.

PREFERRED STOCK

     The Articles of Incorporation authorize the Board of Directors to issue, by
resolution, 10,000,000 shares of preferred stock, in classes or series, having
such designations, powers, preferences, rights, and limitations as the Board of
Directors may from time to time determine. The conversion ratio is subject to
certain anti-dilution adjustments, and the holder of each share of preferred
stock is entitled to one vote for each share of common stock into which it would
convert. In 1997, 82,450 shares of Series B Convertible Preferred Stock were

ITEM 4.  RECENT SALES OF UNREGISTERED SECURITIES

     During 1997, the Company entered into a five-year employment agreement with
its president. As part of the employment agreement, the Company granted options
to the president to purchase up to 2,500,000 shares of the Company's $.0001 par
value restricted Common Stock. In accordance with APB 25, the Company recognized
$500,000 of compensation expense and $250,000 of deferred compensation. The
options are subject to vesting conditions and have exercise prices between $1.50
and $3.00 per share.

     On October 22, 1997, the Company entered into three agreements to grant
options to purchase common stock restricted under Securities Exchange Commission
Rule 144 in consideration for consulting services. The options were granted for
a total of 573,150 shares of the Company's $.0001 par value common stock with an
exercise price of $.07 per share. All of the options were exercisable at

Common Stock options. All of these options were exercised in 1998. The options
were issued pursuant to Rule 701 of the Securities Act. During 1998, the Company

with ISS, pursuant to which it issued 2,000,000 shares of its Common Stock under
Section 4(2) of the Securities Act in exchange for the outstanding shares of ISS
(then a privately held company). ISS is now a wholly owned subsidiary of the
Company. In addition to the issuance of shares, the ISS shareholders also
received two seats on the Board of Directors of the Company, and former
employees of ISS became employees of the Company; such employees to receive
performance options for an additional 300,000 shares.

     In August 1998, the Company secured intellectual property, including
patents and trade secrets, from an individual who had acquired them from
American Rocket Company (AMROC), an aerospace company active during the late
1980s and early 1990s. The consideration for the intellectual property was
warrants to purchase a minimum of 100,000 and a maximum of 3,000,000 shares of
the Company's Common Stock over the following 10-year period, depending on the
Company's annual revenues. The shares issued to AMROC, were issued pursuant to
the private offering exemption in Section 4(2) of the Securities Act. In return
for the exclusive royalty free right to use, sell and apply patents and other
technology developed by an individual, the Company issued warrants to purchase
25,000 shares of Common Stock at 50% of their fair market value on the date of
issuance. The warrants were issued pursuant to Section 4(2) of the Securities
Act. The individual will receive warrants to purchase a minimum of 75,000 shares
and a maximum of 3,000,000 shares of Common Stock at 50% of their fair market
value on the date of issuance. The number of shares varies with revenue
generated by the technology on specific dates.

     On October 1, 1998 the Company entered into a Common Stock Exchange
Agreement with SIL pursuant to Section 4(2) of the Securities Act. Upon
execution of the Agreement, the Company obtained all outstanding shares of SIL
(then a privately held company) and issued 1,000,000 shares of the Company's
Common Stock to the SIL shareholders. The Company also agreed to issue
additional shares of Common Stock valued at $1,000,000 to the SIL shareholders
in installments, with the final installment due on July 15, 2000. SIL
shareholders also received incentive stock options for 500,000 additional
shares. SIL became a wholly owned subsidiary as a result of this Agreement. In
December 1999, the Company and SIL negotiated a rescission of the Share
Acquisition Agreement.

     In 1998, the Company's Chief Executive Officer, James W. Benson, purchased
100,000 shares of the Company's common stock at a per share price of $0.50
pursuant to Section 4(2) of the Securities Act. All of these options have been
exercised, and the underlying shares have been issued with the appropriate
resale restrictions.

     During 1998, the Company entered agreements with sales, investor relations
and public relations firms to perform services for the Company. In return for
these services, the Company issued 92,190 shares of its Common Stock pursuant to
the exemption in Section 4(2) of the Securities Act and recorded expenses of
approximately $120,000.

     As part of an employment agreement with Jan King, the Company issued 5,000
shares of Common Stock as a signing bonus and recorded $8,750 of compensation
expense. The agreement renews annually and can be canceled by either party under
provisions of the agreement. Upon renewal of the agreement, the employee will
receive 5,000 shares of Common Stock annually for two years. The agreement also
includes 50,000 stock options with exercise prices of between $2 and $3 per
share. These options will vest upon future events occurring.

     In conjunction with the Common Stock Exchange Agreement between the Company
and SIL, the Company granted options to five key employees to purchase up to
350,000 shares of restricted Common Stock with exercise prices between $1.50 and
$3.50 per share. The vesting of these options is contingent on several future
events. Should these events occur, no options would vest. These options are
being issued pursuant to Rule 701 of the Securities Act. The option agreements
were rescinded in December 1999 as part of the mutual rescission and release
between the Company and the former SIL shareholders.

     During 1999, the Company entered into agreements with sales, investor
relations, public relations firms and an employee to perform services for the
Company. For the three and nine months ended September 30, 1999, the Company
issued 7,074 and 30,656 shares of its common stock and recorded expense of
approximately $11,000 and $164,000, respectively.

     All of the above referenced securities are restricted by Rule 144 of the
Securities Act of 1933.

     During 1998 and 1999, the Company issued 970,235 shares of its Common
Stock, priced at an average of $0.66 per share for a total amount of $634,412.
These shares were issued in reliance on the exemption from registration provided
by Rule 504 under Section 3(b) of the Securities Act.

      On August 26, 1999, the Colorado Securities Division made effective the
Company's registration statement on Form U-7 for offers and sales to Colorado
residents. The offering is for an aggregate amount of $350,000 in units of the
Company's $.0001 par value common stock and re-pricing warrants. Following
closing on the first $350,000 in units, the Company filed a post-effective
amendment to the Form U-7 registration statement to raise the aggregate amount
of the offering to $730,000. The post-effective amendment was made effective on
October 13, 1999. The Company sold $10,000 in units pursuant to the
post-effective amendment for an approximate price of $0.83 per share. The
Company made a decision to close this offering in December 1999.


ITEM 5.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     The Company's Articles of Incorporation contain a provision which, in
accordance with Colorado law, eliminates or limits the personal liability of
directors and officers of the Company for monetary damages for certain breaches
of their duty of care or other duty if he or she acted in good faith and in a
manner they believed to be in, or not opposed to, the best interests of the
Company, except that no indemnification shall be made in respect of any claim,
issue or matter as to which such person shall have been adjudged to be liable
for negligence or misconduct in the performance of his or her duty to the
Company unless otherwise determined by the court before which such action was
brought. The Company believes this provision is essential to maintain and
improve its ability to attract and retain competent directors. These
indemnification provisions do not reduce the exposure of directors and officers
to liability under federal and state securities laws, nor do they limit the
shareholders' ability to obtain injunctive relief or other equitable remedies
for a violation of a director's or officer's duty to the Company or its
shareholders, although such equitable remedies may not be an effective remedy in
certain circumstances.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers or persons controlling the
Company pursuant to the foregoing provisions, the Company is informed that it is
the opinion of the Securities and Exchange Commission that such indemnification
is against public policy and therefore unenforceable.

REPORT ON REVIEWED CONSOLIDATED FINANCIAL STATEMENTS



To the Board of Directors of
SPACEDEV, INC.

We have reviewed the accompanying consolidated balance sheet of SPACEDEV, INC.
AND SUBSIDIARY (the "Company") (see Note 1(c) to the consolidated financial
statements) as of September 30, 1999, and the related consolidated statements of
operations, stockholders' equity, and cash flows for the three and nine months
ended, in accordance with Statements on Standards for Accounting and Review
Services issued by the American Institute of Certified Public Accountants. All
information included in these consolidated financial statements is the
representation of the management of SPACEDEV, INC.

A review consists principally of inquiries of Company personnel and analytical
procedures applied to financial data. It is substantially less in scope than an
audit in accordance with generally accepted auditing standards, the objective of
which is the expression of an opinion regarding the consolidated financial
statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should
be made to the accompanying consolidated financial statements in order for them
to be in conformity with generally accepted accounting principles.

As discussed in Note 1(e) to the consolidated financial statements, the method
of accounting for its investment in SIL, a wholly-owned subsidiary, changed
effective January 1, 1999.

1.    SUMMARY OF         A summary of the Company's significant accounting
      SIGNIFICANT        policies consistently applied in the preparation of
      ACCOUNTING         the accompanying consolidated financial statements
      POLICIES           follows.

(a)   NATURE OF          SPACEDEV, INC. (the "Company") was incorporated under
      OPERATIONS         the laws of Colorado on December 23, 1996 as Pegasus
                         Development Group, Inc. (PDGI). The Company is engaged
                         in the commercial development of low cost satellites
                         and their subsystems, as well as engineering technical
                         services to major aerospace companies. The principal
                         markets of the Company are the United States and
                         Europe. See Note 11(a).

                         The principal activities from inception have been
                         organizational matters, the sale and issuance of shares
                         of its $.0001 par value common stock and $.001 par
                         value preferred stock as part of a public stock
                         offering and the execution of a stock acquisition
                         agreement.

                         PDGI was originally formed for the purpose of entering
                         the real estate industry. SpaceDev LLC was formed for
                         commercial space exploration. On October 22, 1997, the
                         PDGI acquired 100 percent, or 1,000,000 shares, of
                         SPACEDEV'S $.001 par value common stock from SpaceDev,
                         LLC in exchange for 82,450 shares of the Company's
                         $.001 par value convertible, preferred stock, pursuant
                         to a comprehensive plan of reorganization of PDGI.
                         Following the acquisition of SPACEDEV, SPACEDEV was
                         merged into PDGI and the name of the corporation was
                         changed to SPACEDEV, INC. After the reorganization, the
                         former stockholders of SPACEDEV owned a majority of the
                         outstanding common stock of the Company, after giving
                         effect to the conversion privilege of the preferred
                         stock which is convertible into 8,245,000 shares of
                         common stock.

                         For accounting purposes, the transaction has been
                         accounted for as a recapitalization of Company with the
                         Company as the acquirer (reverse acquisition). Since
                         SPACEDEV had, prior to the recapitalization, minimal
                         assets, the recapitalization has been accounted for as
                         the sale of 1,755,000 shares for net assets of $1,232.

                         The Company's preferred shares reflected in the
                         consolidated financial statements have been restated
                         based upon the exchange rates of preferred stock issued
                         in connection with the acquisition.

                                                                               9

                                                                  AND SUBSIDIARY
                                      NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
================================================================================

(b)   LIQUIDITY          The accompanying consolidated financial statements as
                         of September 30, 1999 and for the three and nine months
                         ended September 30, 1999 have been prepared assuming
                         the Company will continue as a going concern. However,
                         the Company has a negative working capital of
                         approximately $3,135,000 as of September 30, 1999 and
                         incurred a net loss of approximately $2,162,000 for the
                         nine months ended September 30, 1999. Subsequent to
                         September 1999, management intends to raise additional
                         equity financing to fund future operations and
                         commitments. There is no assurance that the new equity
                         will be sufficient to meet the Company's needs.
                         Additionally, there is no assurance that additional
                         equity financing needed to fund operations will be
                         consummated or obtained in sufficient amounts necessary
                         to meet the Company's needs.

                         The accompanying consolidated financial statements do
                         not include any adjustments to reflect the possible
                         future effects on the recoverability and classification
                         of assets or the amounts and classification of
                         liabilities that may result from the possible inability
                         of the Company to continue as a going concern.

(c)   PRINCIPLES OF      The consolidated financial statements include the
      CONSOLIDATION      accounts of the Company and its wholly-owned
                         subsidiary, Integrated Space Systems, Inc. (ISS) (a
                         California corporation). See Note 1(e). All significant
                         intercompany balances and transactions have been
                         eliminated in the consolidation.

(d)   USE OF             The preparation of financial statements in conformity
      ESTIMATES          with generally accepted accounting principles requires
                         management to make estimates and assumptions that
                         affect certain reported amounts and disclosures.
                         Accordingly, actual results could differ from those
                         estimates. Significant estimates used in preparing
                         these consolidated financial statements include those
                         assumed in computing the valuation allowance on
                         deferred tax assets. See Note 6. It is reasonably
                         possible that the significant estimates used will
                         change within the next year.

                                                                              10

                                                                  AND SUBSIDIARY
                                      NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
================================================================================

(e)   INVESTMENT IN      During October 1998, the Company acquired 100 percent
      SUBSIDIARY         of SIL (an entity in England). The transaction was
                         accounted for under the purchase method of accounting
                         with the aggregate of the purchase price in excess of
                         the fair market value of the assets acquired being
                         capitalized as goodwill. The cost of the acquired
                         entity was $3,100,000 which was all capitalized as
                         goodwill. Amortization expense was approximately
                         $258,000 for the three months ended December 31, 1998.

                         The Company issued 1,000,000 shares of restricted
                         common stock for the outstanding common stock of SIL.
                         As part of the acquisition, the Company was to issue
                         $1,000,000 of common stock in four semi-annual
                         installments over the next two years. As a result of
                         the Mutual Release and Rescission Agreement discussed
                         below, the acquisition price payable of $1,000,000 is
                         included as a current liability.

                         Under the Revenue and Profit Incentive Stock Option
                         Plan and the Profit Sharing Stock Issuance Plan, the
                         former stockholders of SIL also received options to
                         purchase up to 500,000 additional shares at a price to
                         be determined in the year of grant should certain
                         future events occur in each of the next three years.
                         During 1998, 100,000 options expired as the qualifying
                         events did not occur. Effective December 17, 1999, all
                         remaining options have been cancelled.

                         The consolidated statement of operations for the year
                         ended December 31, 1998 included the operating results
                         from this entity.

                         In December 1999, the Company entered into a Mutual
                         Release and Rescission of Agreement to rescind the
                         original acquisition of SIL effective October 1, 1998.
                         The accounts of SIL were originally included in the
                         consolidated balances of the consolidated financial
                         statements of the Company. Effective January 1, 1999,
                         the investment in SIL was accounted for under the
                         equity method.

                         As a result of the change in accounting for SIL,
                         approximately $2,842,000 of unamortized goodwill was
                         reclassified to investment in subsidiary. In addition,
                         the Company's consolidated net loss decreased by
                         approximately $258,000 and $775,000 for the three and
                         nine months ended September 30, 1999. The decreases
                         resulted from the reversal of goodwill amortization.

================================================================================

(f)   DEPRECIATION       Fixed assets are depreciated over their estimated
      AND                useful lives of three to eight years using the
      AMORTIZATION       straight-line method of accounting. Leasehold
                         improvements are amortized over the shorter of the
                         estimated useful lives of the assets or the remaining
                         lease term.

                         Goodwill and other intangible assets were created upon
                         the acquisition of the Company's subsidiaries.
                         Intangible assets are amortized over their assets
                         estimated future useful lives on a straight-line basis
                         over three to five years. Goodwill and other
                         intangibles are periodically reviewed for impairment
                         based on an assessment of future operations to ensure
                         they are appropriately valued in accordance with
                         Statement of Financial Accounting Standards No. 121,
                         "Accounting for the Impairment of Long-Lived Assets and
                         for Long-Lived Assets to be Disposed Of."

(g)   RESEARCH AND       The Company is actively engaged in new product
      DEVELOPMENT        development efforts. Research and development
                         expenditures relating to possible future products are
                         expensed as incurred. Total expense was approximately
                         $4,000 and $68,000 for the three and nine months ended
                         September 30, 1999, respectively.

(h)   ADVERTISING        The Company follows the policy of charging the costs of
                         advertising to expense as incurred. The Company did not
                         incur advertising expenses for either the three months
                         or nine months ended September 30 1999.

(i)   INCOME             Deferred income taxes are recognized for the tax
      TAXES              consequences in future years of differences between
                         the tax basis of assets and liabilities and their
                         financial reporting amounts at each period end based on
                         enacted tax laws and statutory tax rates applicable to
                         the periods in which the differences are expected to
                         affect taxable income. Valuation allowances are
                         established when necessary to reduce deferred tax
                         assets to the amount expected to be realized. Income
                         tax expense is the combination of the tax payable for
                         the period and the change during the period in deferred
                         tax assets and liabilities.

      STANDARDS          130, "Reporting Comprehensive Income." This Statement
                         was adopted in 1998. In accordance with the Statement,
                         comprehensive income is presented in the consolidated
                         statements of stockholders' equity for the three and
                         nine months ended September 30, 1999.

                         Statement of Financial Accounting Standards No. 133,

                         not in the past nor does it anticipate, that it will
                         engage in transactions involving derivative instruments
                         which will impact the consolidated financial
                         statements.

(k)   STOCK-BASED        In October 1995, the Financial Accounting Standards
      COMPENSATION       Board issued Statement of Financial Accounting

                         Compensation" (SFAS 123). The Company adopted SFAS 123
                         in 1997. The Company has elected to measure
                         compensation expense for its stock-based employee
                         compensation plans using the intrinsic value method
                         prescribed by APB Opinion 25, "Accounting for Stock
                         Issued to Employees" (APB 25) and has provided pro
                         forma disclosures as if the fair value based method
                         prescribed SFAS 123 has been utilized. See Note 8(d).

(l)   COMMON STOCK       The Company has valued its stock and stock options
      AND STOCK          issued to non-employees at fair value in accordance
      OPTIONS TO         with the accounting prescribed in SFAS 123 which states
      NON-EMPLOYEES      that all transactions in which goods or services are
                         received for the issuance of equity instruments shall
                         be accounted for based on the fair value of the
                         consideration received or the fair value of the equity
                         instruments issued, whichever is more reliably
                         measurable.

(m)   NET LOSS PER       Net loss per common share has been computed on the
      COMMON SHARE       basis of the weighted average number of shares
                         outstanding, according to the rules of Statement of
                         Financial Accounting Standards No. 128, "Earnings per
                         Share."

6.    INCOME             Deferred income taxes are provided for temporary
      TAXES              differences in recognizing certain income and expense
                         items for financial and tax reporting purposes. The
                         deferred tax asset of $1,494,000 as of September 30,
                         1999, consisted primarily of the income tax benefits
                         from net operating loss carryforwards and research and
                         development credits. A valuation allowance has been
                         recorded to fully offset the deferred tax asset as
                         realization of such asset is not assured. The valuation
                         allowance increased approximately $544,000 in the nine

7.    EMPLOYEE
      BENEFIT PLAN

(a)   PROFIT SHARING     During 1997, the Company adopted a 401(k) retirement
      401(K) PLAN        savings plan for its U.S. employees which allows each
                         eligible employee to voluntarily make pre-tax salary
                         contributions up to 15 percent of their compensation.
                         The Company may elect to make a matching contribution.
                         During the three and nine months ended September 30,
                         1999, the Company did not contribute to the Plan. The
                         total Company contribution and participant salary
                         reduction may not exceed 25 percent of the compensation

                         the option of the holder, into 100 shares of common
                         stock. The conversion ratio is subject to certain
                         anti-dilution adjustments, and the holder of each share
                         of preferred stock is entitled to one vote for each
                         share of common stock into which it would convert.
                         These shares were converted to 8,245,000 shares of
                         common stock on May 11, 1999.

(b)   COMMON             During 1999, the Company entered agreements with sales,
                         investor relations and public relations firms and
                         employees to perform services for the Company. For the
                         three and nine months ended September 30, 1999, the
                         Company issued 7,074 and 30,656 shares of its common
                         stock and recorded expense of approximately $11,000 and
                         $164,000, respectively.

                         During 1998, the Company entered a five-year employment
                         agreement with a key employee. The agreement renews
                         annually and can be canceled by either party under
                         provisions of the agreement. Upon renewal of the
                         agreement, the employee will receive 5,000 shares of
                         common stock annually for two years. The agreement also
                         includes 50,000 shares of stock these shares become

                         25,000 shares of common stock at 50 percent of their
                         fair market value on the date of issuance, in return
                         for the exclusive royalty free right to use, sell and
                         apply patents and other technology developed by an
                         individual. The individual will receive warrants to
                         purchase a minimum of 75,000 shares and a maximum of
                         3,000,000 shares of common stock at 50 percent of the
                         fair market value on the date of issuance. The number
                         of shares varies with revenue generated by the
                         technology on specific dates. At September 30, 1999,
                         the unissued warrants were not recorded as the future
                         exercise price of the warrants cannot be estimated.


(d)   STOCK              During 1997, the Company entered into a five-year
                         employment agreement with its president. As part of the

                         the president to purchase up to 2,500,000 shares of the

                         of compensation expense and $250,000 of deferred
                         compensation. The options are subject to vesting
                         conditions and have exercise prices between $1.50 and
                         $3.00 per share.

                         The Company has elected to account for its stock-based
                         compensation plans under APB 25. However, the Company
                         has computed, for pro forma disclosure purposes, the
                         value of all options granted during the three and nine
                         months ended September 30, 1999 using the minimum value
                         method as prescribed by SFAS 123. Under this method,
                         the Company used the risk-free interest rate at date of
                         grant, expected volatility, expected dividend yield and
                         the expected life of the options to determine the fair
                         value of options granted. The risk-free interest rates
                         ranged from 5.4 percent to 6.0 percent; expected
                         volatility of 100% and the dividend yield was assumed
                         to be zero, and the expected life of the options was
                         assumed to be five years based on the average vesting
                         period of options granted.

                         If the Company had accounted for these options in
                         accordance with SFAS 123, the total value of options
                         granted during the three and six months ended September
                         30, 1999 would be amortized on a pro forma basis over
                         the vesting period of the options. Thus, the Company's
                         consolidated net loss would have increased as reflected
                         in the following pro forma amounts:

      CREDIT RISK        The Company maintains cash balances at various
                         financial institutions primarily located in San Diego.

      OR LOSS            Segment profit or loss includes substantially all of
                         the segment's costs of production, distribution and
                         administration. The Company manages income taxes on a
                         global basis. Thus, management evaluates segment
                         performance based on profit or loss before income

12.   SETTLEMENT         In August 1998, the U.S. Securities and Exchange
      WITH U.S.          Commission (SEC) alleged that the Company and its
      SECURITIES AND     chairman made statements on the Internet regarding
      EXCHANGE           revenue and earnings estimates without a reasonable
      COMMISSION         basis and also misrepresented a financing agreement it
                         had with a broker-dealer.

                         During April 1999, the Company and its chairman agreed
                         to settle the SEC's charges. Neither party paid any
                         fines. Under the settlement, the Company neither
                         admitted nor denied wrongdoing. The Company and its
                         chairman agreed to be subject to stiffer sanctions for
                         any future violations.

13.   SUBSEQUENT         In November 1999, the Company entered an employment
      EVENT              agreement with a key employee. The agreement can be
                         terminated by either party under certain circumstances.
                         The agreement also includes stock options contingent on
                         future events as well as grants under the Company's
                         Incentive Stock Option Plan.

INDEPENDENT AUDITORS' REPORT


To the Board of Directors of
SPACEDEV, INC.

We have audited the accompanying consolidated balance sheet of SPACEDEV, INC.
AND SUBSIDIARIES (the "Company")(see Note 1(c) to the consolidated financial
statements) as of December 31, 1998, and the related consolidated statements of
operations, stockholders' equity, and cash flows for the year then ended. These
consolidated statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audit. We did not audit the financial statements of
SPACE INNOVATIONS LIMITED, a wholly-owned subsidiary, whose statements reflect
total assets constituting 20% of consolidated assets as of December 31, 1998,
and net sales constituting 36% of consolidated net sales for the three-month
period then ended. Those statements were audited by other auditors whose report
has been furnished to us, and our opinion, insofar as it related to the amounts
included for SPACE INNOVATIONS LIMITED is based solely on the report of other
auditors. The financial statements of SPACEDEV, INC. as of December 31, 1997
were audited by other auditors whose report dated January 30, 1998, expressed an
unqualified opinion on those statements.

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

In our opinion, based on our audit and the report of other auditors, the
consolidated financial statements referred to in the first paragraph present
fairly, in all material respects, the financial position of SPACEDEV, INC. AND
SUBSIDIARIES as of December 31, 1998, and the results of its operations and its
cash flows for the year then ended in conformity with generally accepted
accounting principles.

1.    SUMMARY OF         A summary of the Company's significant accounting
      SIGNIFICANT        policies consistently applied in the preparation of the
      ACCOUNTING         accompanying consolidated financial statements follows.
      POLICIES

(a)   NATURE OF          SPACEDEV, INC. (the "Company") was incorporated as
                         Pegasus Development Group, Inc. The Company is engaged
                         in the commercial development of low cost satellites
                         and their subsystems, as well as engineering technical
                         services to major aerospace companies. The principal
                         markets of the Company are 65% in the United States and
                         35% in Europe. (See Note 11(a))

                         The Company was incorporated under the laws of Colorado
                         on December 23, 1996 as Pegasus Development Group, Inc.
                         (PDGI). The principal activities from inception have
                         been organizational matters, the sale and issuance of
                         shares of its $.0001 par value common stock and $.001
                         par value preferred stock as part of a public stock
                         offering and the execution of a stock acquisition
                         agreement.

                         PDGI was originally formed for the purpose of entering
                         the real estate industry. However, on October 22, 1997,
                         the PDGI acquired 100 percent, or 1,000,000 shares, of
                         SpaceDev's $.001 par value common stock from SpaceDev,
                         LLC in exchange for 82,450 shares of the Company's
                         $.001 par value convertible, preferred stock, pursuant
                         to a comprehensive plan of reorganization of PDGI.
                         Following the acquisition of SpaceDev, SpaceDev was
                         merged into PDGI and the name of the corporation was
                         changed to SpaceDev, Inc. After the reorganization, the
                         former shareholders of SpaceDev owned a majority of the
                         outstanding common stock of the Company, after giving
                         effect to the conversion privilege of the preferred
                         stock which is convertible into 8,245,000 shares of
                         common stock.

                         For accounting purposes, the transaction has been
                         accounted for as a recapitalization of Company with the
                         Company as the acquirer (reverse acquisition). Since
                         SpaceDev had, prior to the recapitalization, minimal
                         assets, the recapitalization has been accounted for as
                         the sale of 1,755,000 shares for net assets of $1,232.

                         The Companys preferred shares reflected in the
                         consolidated financial statements have been restated
                         based upon the exchange rates of preferred stock issued
                         in connection with the acquisition.

                                                                               9

                                                                AND SUBSIDIARIES
                                      NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
================================================================================

(b)   LIQUIDITY          The accompanying consolidated financial statements as
                         of December 31, 1998 have been prepared assuming the
                         Company will continue as a going concern. However, the
                         Company has a negative working capital of $1,883,061 as
                         of December 31, 1998 and incurred net losses of
                         $1,909,642 and $904,991 for the periods ended December
                         31, 1998 and 1997, respectively. Subsequent to December
                         1998, management intends to raise additional equity
                         financing to fund future operations and commitments.
                         There is no assurance that the new equity will be
                         sufficient to meet the Company's needs. Additionally,
                         there is no assurance that additional equity financing
                         needed to fund operations will be consummated or
                         obtained in sufficient amounts necessary to meet the
                         Company's needs.

                         The accompanying consolidated financial statements do
                         not include any adjustments to reflect the possible
                         future effects on the recoverability and classification
                         of assets or the amounts and classification of
                         liabilities that may result from the possible inability
                         of the Company to continue as a going concern.


(c)   PRINCIPLES OF      The consolidated financial statements include the
      CONSOLIDATION      accounts of the Company and its wholly-owned
                         subsidiaries, Space Innovations Limited (SIL) (a United
                         Kingdom entity) and Integrated Space Systems, Inc.
                         (ISS) (a California corporation). All significant
                         intercompany balances and transactions have been
                         eliminated in the consolidation.

(d)   USE OF             The preparation of financial statements in conformity
                         with generally accepted accounting principles requires
                         management to make estimates and assumptions that
                         affect certain reported amounts and disclosures.
                         Accordingly, actual results could differ from those
                         estimates. Significant estimates used in preparing
                         these consolidated financial statements include those
                         assumed in computing the valuation allowance on
                         deferred tax assets (see Note 6). It is reasonably
                         possible that the significant estimates used will
                         change within the next year.

(e)   INVENTORY          Inventory consists mainly of raw materials and is
                         stated at the lower of cost (first-in, forst-out) or
                         market.

                                                                              10

                                                                AND SUBSIDIARIES

(f)   DEPRECIATION       Fixed assets are depreciated over their estimated
      AND                useful lives of three to eight years using the
      AMORTIZATION       straight-line method of accounting. Leasehold
                         improvements are amortized over the shorter of the
                         estimated useful lives of the assets or the remaining
                         lease term.

                         Goodwill and other intangible assets were created upon
                         the acquisition of the Company's subsidiaries.
                         Intangible assets are amortized over their assets
                         estimated future useful lives on a straight-line basis
                         over three to five years. Goodwill and other
                         intangibles are periodically reviewed for impairment
                         based on an assessment of future operations to ensure
                         they are appropriately valued in accordance with
                         Statement of Financial Accounting Standards No. 121,
                         "Accounting for the Impairment of Long-Lived Assets and
                         for Long-Lived Assets to be Disposed Of."

(g)   RESEARCH AND       The Company is actively engaged in new product
      DEVELOPMENT        development efforts. Research and development
                         expenditures relating to possible future products are
                         expensed as incurred. Total expense was approximately
                         $701,000 and $907,000 for 1998 and 1997, respectively.

(h)   ADVERTISING        The Company follows the policy of charging the costs of
                         advertising to expense as incurred. Advertising
                         expenses were approximately $11,400 for 1998.

(i)   INCOME             Deferred income taxes are recognized for the tax
      TAXES              consequences in future years of differences between the
                         tax basis of assets and liabilities and their financial
                         reporting amounts at each year end based on enacted tax
                         laws and statutory tax rates applicable to the periods
                         in which the differences are expected to affect taxable
                         income. Valuation allowances are established when
                         necessary to reduce deferred tax assets to the amount
                         expected to be realized. Income tax expense is the
                         combination of the tax payable for the year and the
                         change during the year in deferred tax assets and
                         liabilities.

(j)   FOREIGN            For the foreign subsidiary, assets and liabilities are
      CURRENCY           translated at the current year end exchange rate,
                         equity at the historical rate and income statement
                         items at the weighted average exchange rate for the
                         period. Resulting translation adjustments are made
                         directly to a separate component of stockholders
                         equity.

                                                                              11

                                                                AND SUBSIDIARIES

(k)   NEW                In 1997, the Financial Accounting Standards Board
      ACCOUNTING         issued Statement of Financial Accounting Standards No.
      STANDARDS          130, "Reporting Comprehensive Income." This Statement
                         was adopted in 1998. In accordance with the Statement,
                         comprehensive income is presented in the consolidated
                         statements of stockholders' equity for 1998 and 1997.

                         Statement of Financial Accounting Standards No. 133,
                         "Accounting for Derivatives Instrument and Hedging
                         Activities", established accounting and reporting
                         standards for derivative instruments. The Company has
                         not in the past nor does it anticipate, that it will
                         engage in transactions involving derivative instruments
                         which will impact the financial statements.

                         Statement of Position 98-5, "Accounting for Start-up
                         Costs", requires an entity to expense all start-up
                         related costs as incurred for fiscal years beginning
                         after December 15, 1998. The Company believes that this
                         statement will not have a material effect on the
                         Company's accounting for start-up costs.


(l)   STOCK-BASED        In October 1995, the Financial Accounting Standards
      COMPENSATION       Board issued Statement of Financial Accounting
                         Standards No. 123, "Accounting for Stock-Based
                         Compensation" (SFAS 123). The Company adopted SFAS 123
                         in 1997. The Company has elected to measure
                         compensation expense for its stock-based employee
                         compensation plans using the intrinsic value method
                         prescribed by APB Opinion 25, "Accounting for Stock
                         Issued to Employees" (APB 25) and has provided pro
                         forma disclosures as if the fair value based method
                         prescribed SFAS 123 has been utilized. See Note 8(d).

(m)   COMMON STOCK       The Company has valued its stock and stock options
      AND STOCK          issued to non-employees at fair value in accordance
      OPTIONS TO         with the accounting prescribed in SFAS 123 which states
      NON-EMPLOYEES      that all transactions in which goods or services are
                         received for the issuance of equity instruments shall
                         be accounted for based on the fair value of the
                         consideration received or the fair value of the equity
                         instruments issued, whichever is more reliably
                         measurable.

(n)   NET LOSS PER       Net loss per common share has been computed on the
      COMMON SHARE       basis of the weighted average number of shares
                         outstanding, according to the rules of Statement of
                         Financial Accounting Standards No. 128, "Earnings per
                         Share".

                                                                              12

                         Depreciation and amortization expense was approximately
                         $60,807 in 1998.

                         During 1998, the Company entered into construction
                         contracts on its new facility totaling approximately
                         $350,000.

3.    ACQUISITIONS       During 1998, the Company acquired 100% of the
                         outstanding common stock of two entities in San Diego
                         (ISS) and England (SIL) (see Note 8(b)). These
                         transactions were accounted for under the purchase
                         method of accounting with the aggregate of the purchase
                         price in excess of the fair market value of the assets
                         acquired being capitalized as goodwill. The cost of the
                         acquired entities was $5,725,000, of which $5,561,000
                         was capitalized as goodwill.

                         As part of the acquisition of SIL, the Company will
                         issue $1,000,000 of common stock in four semi-annual
                         installments over the next two years. The number of
                         shares issued will be determined on the then quoted
                         fair market value of its common stock. This amount was
                         recorded as acquisition price payable with $500,000 as
                         a current and $500,000 as a long-term liability.

                                                                              13

                         Subsequent to year end, these shares were converted to
                         8,245,000 shares of common stock.

(b)   COMMON             In 1998, the Company issued 2,000,000 and 1,000,000
      STOCK              shares of restricted common stock for 100% of the
                         outstanding stock of ISS and SIL, respectively. See
                         Note 3.

                         During 1998, the Company entered agreements with sales,
                         investor relations and public relations firms to
                         perform services for the Company. In return for these
                         services, the Company issued 92,190 shares of its
                         common stock and recorded expense of approximately
                         $120,000.

                         As part of a five-year employment agreement with a key
                         employee, the Company issued 5,000 shares of common
                         stock as a signing bonus and recorded $8,750 of
                         compensation expense. The agreement renews annually and
                         can be canceled by either party under provisions of the
                         agreement. Upon renewal of the agreement, the employee
                         will receive 5,000 shares of common stock annually for
                         two years. The agreement also includes 50,000 stock
                         options with exercise prices of between $2 and $3 per
                         share. These options will vest upon future events
                         occurring. See Note 8(d).

                         During 1998, the Company recorded approximately
                         $126,000 of compensation expense related to 348,000
                         shares of restricted common stock issued to the
                         president at less than fair market value.

                         During 1998, the Company issued 573,150 shares of
                         common stock upon the exercising of stock options.

                                                                              17

(c) WARRANTS             In return for the exclusive royalty free right to use,
                         sell and apply patents and other technology developed
                         by an individual, the Company issued warrants to
                         purchase 25,000 shares of common stock at 50% of their
                         fair market value on the date of issuance. The
                         individual will receive warrants to purchase a minimum
                         of 75,000 shares and a maximum of 3,000,000 shares of
                         common stock at 50% of the fair market value on the
                         date of issuance. The number of shares varies with
                         revenue generated by the technology on specific dates.
                         At December 31, 1998, the unissued warrants were not
                         recorded as the future exercise price of the warrants
                         cannot be estimated. See Note 3.

(d) STOCK OPTIONS

                         On October 22, 1997, the Company entered into three
                         agreements to grant options to purchase common stock
                         restricted under Securities Exchange Commission Rule
                         144 in consideration for consulting services. The
                         options were granted for a total of 573,150 shares of
                         the Company's $.0001 par value common stock with an
                         exercise price of $.07 per share. All of the options
                         were exercisable at December 31, 1997 and each option
                         was to expire on October 21, 2002. Based on the use of
                         the Black-Scholes option pricing model, the fair value
                         of the stock options issued for these services was
                         $221,333. As a result, the Company recognized $221,333
                         in consulting expense in 1998 related to the issuance
                         of the common stock options. All of these options were
                         exercised in 1998.

                         During 1997, the Company entered into a five-year
                         employment agreement with its president. As part of the
                         employment agreement, the Company granted options to
                         the president to purchase up to 2,500,000 shares of the
                         Company's $.0001 par value restricted common stock. In
                         accordance with APB 25, the Company recognized $500,000
                         of compensation expense and $250,000 of deferred
                         compensation. The options are subject to vesting
                         conditions and have exercise prices between $1.50 and
                         $3.00 per share.

                         During 1998, the Company granted options to five key
                         employees to purchase up to 350,000 shares of
                         restricted common stock with exercise prices between
                         $1.50 and $3.50 per share. The vesting of these options
                         are contingent on several future events. Should these
                         events not occur, no options would vest. Therefore,
                         these options were excluded from the pro forma amounts
                         shown below.

                                                                              18

                         The Company has elected to account for its stock-based
                         compensation plans under APB 25. However, the Company
                         has computed, for pro forma disclosure purposes, the
                         value of all options granted during 1998 and 1997 using
                         the minimum value method as prescribed by SFAS 123.
                         Under this method, the Company used the risk-free
                         interest rate at date of grant, expected volatility,
                         expected dividend yield and the expected life of the
                         options to determine the fair value of options granted.
                         The risk-free interest rates ranged from 5.4% to 6.0%;
                         expected volatility of 30% and a 0% dividend yield was
                         assumed to be zero, and the expected life of the
                         options was assumed to be five years based on the
                         average vesting period of options granted.

                         If the Company had accounted for these options in
                         accordance with SFAS 123, the total value of options
                         granted during 1998 and 1997 would be amortized on a
                         pro forma basis over the vesting period of the options.
                         Thus, the Company's consolidated net loss would have
                         increased as reflected in the following pro forma
                         amounts:

                         financial institutions primarily located in San Diego.
                         Accounts at these institutions are secured by the
                         Federal Deposit Insurance Corporation up to $100,000.
                         The Company has not experienced any losses in such
                         accounts. Management believes that the Company is not
                         exposed to any significant credit risk on cash and cash

(c)   CUSTOMER           During 1998, the Company had two major customers that
                         accounted for sales of approximately $1,142,000 or 55%
                         of consolidated revenue. At December 31, 1998, the
                         amount receivable from these customers was
                         approximately $122,000.

(b)   METHOD OF          Management evaluates the performance of its operating
      DETERMINING        segments separately to individually monitor the
      SEGMENT PROFIT     different factors affecting financial performance.
      OR LOSS            Segment profit or loss includes substantially all of
                         the segment's costs of production, distribution and
                         administration. The Company manages income taxes on a
                         global basis. Thus, management evaluates segment
                         performance based on profit or loss before income
                         taxes, exclusive of any significant gains or losses on
                         the disposition of investments or other assets. The
                         Company typically manages and evaluates equity
                         investments and related income on a segment level.

12.   SETTLEMENT         In August 1998, the U.S. Securities and Exchange
      WITH U.S.          Commission (SEC) alleged that the Company and its
      SECURITIES AND     chairman made statements on the Internet regarding
      EXCHANGE           revenue and earnings estimates without a reasonable
      COMMISSION         basis and also misrepresented a financing agreement it
                         had with a broker-dealer.

                         During April 1999, the Company and its chairman agreed
                         to settle the SEC's charges. Neither party paid any
                         fines. Under the settlement, the Company neither
                         admitted nor denied wrongdoing. The Company and its
                         chairman agreed to be subject to stiffer sanctions for
                         any future violations.

                              (viii) Voting powers, if any; and

                              (ix) Any other relative rights and preferences of
                     shares of such series, including, without limitation, any
                     restriction on an increase in the number of shares of any
                     series theretofore authorized and any limitation or
                     restriction of rights or powers to which shares of any
                     future series shall be subject.

          (b) Shares of Common Stock. The rights of holders of shares of common
      stock to receive dividends or share in the distribution of assets in the
      event of liquidation, dissolution or winding up of the affairs of the
      corporation shall be subject to the preferences, limitations and relative
      rights of the shares of preferred stock fixed in the resolution or
      resolutions which may be adopted from time to time by the Board of
      Directors of the corporation providing for the issuance of one or more
      series of shares of preferred stock.

          The capital stock, after the subscription price has been paid in,
shall not be subject to assessment to pay the debts of the corporation. Any
stock of the corporation may be issued for money, property, services rendered,
labor done, cash advances for the corporation or for any other assets of value

          The Board of Directors shall have power and authority to sell, lease,
exchange or otherwise dispose of all or substantially all the property or assets
of the corporation, including its goodwill, if not in the usual and regular
course of its business, upon such terms and conditions as the Board of Directors
may determine, provided that such sale shall be authorized or ratified by the
affirmative vote of the shareholders of at least a majority of the shares
entitled to vote thereon at a shareholders meeting called for that purpose, or
when authorized or ratified by the written consent of all the shareholders of
the shares entitled to vote thereon.

          The Board of Directors shall have the power and authority to merge or

                                   ARTICLE VI

          The following provisions are inserted for the management of the
business and for the conduct of the affairs of the corporation, and the same are
in furtherance of and not in limitation of the powers conferred by law.

          No contract or other transactions of the corporation with any other
person, firm or corporation, or in which this corporation is interested, shall
be affected or invalidated by (a) the fact that any one or more of the directors
or officers of this corporation is interested in or is a director or officer of
such other firm or corporation; or (b) the fact that any director or officer of
this corporation, individually or jointly with others, may be a party to or may
be interested in any such contract or transaction, so long as the contract or
transaction is authorized, approved or ratified at a meeting of the Board of
Directors by sufficient vote thereon by directors not interested therein, to
which such fact or relationship or interest has been disclosed, or so long as
the contract or transaction is fair and reasonable to the corporation. Each
person who may become a director or officer of the corporation is hereby
relieved from any liability that might otherwise arise by reason of his
contracting with the corporation for the benefit of himself or any firm or
corporation in which he may be in any way interested.

          The officers, directors and other members of management of this
corporation shall be subject to the doctrine of corporate opportunities only
insofar as it applies to business opportunities in which this corporation has
expressed an interest as determined from time to time by the corporation's Board
of Directors as evidenced by resolutions appearing in the corporation's minutes.
When such areas of interest are delineated, all such business opportunities
within such areas of interest which come to the attention of the officers,
directors and other members of management of this corporation shall be disclosed
promptly to this corporation and made available to it. The Board of Directors
may reject any business opportunity presented to it and thereafter any officer,
director or other member of management may avail himself of such opportunity.
Until such time as this corporation, through its Board of Directors, has
designated an area of interest, the

                                       5
<PAGE>

officers, directors and other members of management of this corporation shall be
free to engage in such areas of interest on their own and the provisions hereof
shall not limit the rights of any officer, director or other member of
management of this corporation to continue a business existing prior to the time
that such area of interest is designated by this corporation. This provision
shall not be construed to release any employee of the corporation (other than an
officer, director or member of management) from any duties which he may have to
the corporation.


                                   ARTICLE VII

          Each director and officer of the corporation shall be indemnified by
the corporation as follows:

                (a) The corporation shall indemnify any person who was or is a
          party, or is threatened to be made a party, to any threatened, pending
          or completed action, suit or proceeding, whether civil, criminal,
          administrative or investigative (other than an action by or in the
          right of the corporation), by reason of the fact that he is or was a
          director, officer, employee or agent of the corporation, or is
          otherwise serving at the request of the corporation as a director,
          officer, employee or agent of another corporation, partnership, joint
          venture, trust or other enterprise, against expenses (including
          attorneys' fees), judgments, fines and amounts paid in settlement,
          actually and reasonably incurred by him in connection with such
          action, suit or proceeding, if he acted in good faith and in a manner
          he reasonably believed to be in, or not opposed to, the best interests
          of the corporation, and, with respect to any criminal action or
          proceeding, had no reasonable cause to believe his conduct was
          unlawful. The termination of any action, suit or proceeding, by
          judgment, order, settlement, conviction upon a plea of nolo contendere
          or its equivalent, shall not of itself create a presumption that the
          person did not act in good faith and in a manner he reasonably
          believed to be in, or not opposed to, the best interests of the
          corporation and, with respect to any criminal action or proceeding,
          had reasonable cause to believe the action was unlawful.

                (b) The corporation shall indemnify any person who was or is a
          party, or is threatened to be made A party, to any threatened, pending
          or completed action or suit by or in the right of the corporation, to
          procure a judgment in its favor by reason of the fact that he is or
          was a director, officer, employee or agent of the corporation, or is
          or was serving at the request of the corporation as a director,
          officer, employee or agent of another corporation, partnership, joint
          venture, trust or other enterprise against expenses (including
          attorney's fees) actually and reasonably incurred by him in connection
          with the defense or settlement of such action or suit, if he acted in
          good faith and in a manner he reasonably believed to be in, or not
          opposed to, the best interests of the corporation, except that no
          indemnification shall be made in respect of any claim, issue or matter
          as to which such person shall have been adjudged to be liable for
          negligence or misconduct in the performance of his duty to the
          corporation, unless, and only to the extent that, the court in which
          such action or suit was brought shall determine upon application that,
          despite the adjudication of liability, but in view of all
          circumstances of the case, such person is fairly and reasonably
          entitled to indemnification for such expenses which such court deems
          proper.

                (c) To the extent that a director, officer, employee or agent of
          the corporation has been successful on the merits or otherwise in
          defense of any action, suit or proceeding referred to in Sections (a)
          and (b) of this Article, or in defense of any claim, issue or matter
          therein, he shall be indemnified against expenses

                                       6
<PAGE>

          (including attorneys' fees) actually and reasonably incurred by him in
          connection therewith.

                (d) Any indemnification under Section (a) or (b) of this Article
          (unless ordered by a court) shall be made by the corporation only as
          authorized in the specific case upon a determination that
          indemnification of the officer, director and employee or agent is
          proper in the circumstances, because he has met the applicable
          standard of conduct set forth in Section (a) or (b) of this Article.
          Such determination shall be made (i) by the Board of Directors by a
          majority vote of a quorum consisting of directors who were not parties
          to such action, suit or proceeding, or (ii) if such quorum is not
          obtainable or, even if obtainable, a quorum of disinterested directors
          so directs, by independent legal counsel in a written opinion, or
          (iii) by the affirmative vote of the holders of a majority of the
          shares of stock entitled to vote and represented at a meeting called
          for such purpose.

                (e) Expenses (including attorneys' fees) incurred in defending a
          civil or criminal action, suit or proceeding may be paid by the
          corporation in advance of the final disposition of such action, suit
          or proceeding, as authorized in Section (d) of this Article, upon
          receipt of an understanding by or on behalf of the director, officer,
          employee or agent to repay such amount, unless it shall ultimately be
          determined that he is entitled to be indemnified by the corporation as
          authorized in this Article.

                (f) The Board of Directors may exercise the corporation's power
          to purchase and maintain insurance on behalf of any person who is or
          was a director, officer, employee or agent of the corporation, or is
          or was serving at the request of the corporation as a director,
          officer, employee or agent of another corporation, partnership, joint
          venture, trust or other enterprise, against any liability asserted
          against him and incurred by him in any such capacity, or arising out
          of his status as such, whether or not the corporation would have the
          power to indemnify him against such liability under this Article.

                (g) The indemnification provided by this Article shall not be
          deemed exclusive of any other rights to which those seeking
          indemnification may be entitled under these Articles of Incorporation,
          the Bylaws, agreements, vote of the shareholders or disinterested
          directors, or otherwise, both as to action in his official capacity
          and as to action in another capacity while holding such office, and
          shall continue as to a person who has ceased to be a director,
          officer, employee or agent and shall inure to the benefit of the heirs
          and personal representatives of such a person.


                                  ARTICLE VIII

          The initial registered and principal office of said corporation shall
be located at 3351 South Magnolia Street, Denver, Colorado 80224, and the

the City and County of Denver, or any other place in the State of Colorado or
beyond the limits of the State of Colorado, in other states or territories of

          Whenever a compromise or arrangement is proposed by the corporation
between it and its creditors or any class of them, and/or between said
corporation and its shareholders or any class of them, any court of equitable
jurisdiction may, on the application in a summary way by said corporation, or by
a majority of its stock, or on the application of trustees in dissolution, order

<PAGE>

which shares are subject to agreements under which the Company has the option
or obligation to repurchase such shares: (i) at not greater than the fair market

Distribution shall be deemed to be the fair market value of such property as
determined in good faith by the Board.

               (c) PAYMENT ON CONVERSION. If the Company shall have any accrued
and unpaid dividends with respect to any Series B Stock, then immediately prior
to, and upon a conversion of any of the Series B Stock as provided in SECTION 5,
the Company shall, subject to the legal availability of funds and assets
therefor, pay in cash or Common Stock (or a combination thereof) to the holder
of the shares of Series B Stock being converted the full amount of any dividends
accrued and unpaid on such shares. Upon any such conversion, if the Board elects
to pay dividends with respect to any Series B Stock in Common Stock, the Board
shall determine in good faith the total fair market value of such shares, equal
to the balance of all accrued but unpaid dividends not paid in cash.

          3. LIQUIDATION RIGHTS. In the event of any liquidation, dissolution or
winding up of the Company, whether voluntary or involuntary, the funds and
assets of the Company that may be legally distributed to the Company's
shareholders (the "AVAILABLE FUNDS AND ASSETS") shall be distributed to
shareholders in the following manner:

               (a) LIQUIDATION. The holder of each share of Series B Stock then
issued and outstanding shall be entitled to be paid, out of the Available Funds
and Assets, ratably with any payment or distribution (or any setting apart of
any payment or distribution) of any Available Funds and Assets on any shares of
Common Stock, an amount per share equal to

                                       -2-

<PAGE>

the amount allocated to each share of Common Stock and then multiplied by 100,
plus all accrued and unpaid cumulative dividends thereon.

               (b) MERGER OR SALE OF ASSETS. A (i) consolidation or merger of
the Company with or into any other corporation or corporations in which the
holders of record of the Company's outstanding shares immediately before such
consolidation or merger do not, immediately after such consolidation or merger,
hold (by virtue of securities issued as consideration in such transaction or
otherwise) a majority of the voting power of the surviving Corporation of such
consolidation or merger; or (ii) sale of all or substantially all of the assets
of the Company, shall each be deemed to be a liquidation, dissolution or winding
up of the Company as those terms are used in this SECTION 3.

               (c) NON-CASH CONSIDERATION. If any assets of the Company
distributed to shareholders in connection with any liquidation, dissolution, or
winding up of the Company are other than cash, then the value of such assets
shall be their fair market value as determined by the Board, EXCEPT THAT any
securities to be distributed to shareholders in a liquidation, dissolution, or
winding up of the Company shall be valued as follows:

                    (i) The method of valuation of securities not subject to
investment letter or other similar restrictions on free marketability shall be
as follows:

                         (A) if the securities are then traded on a national
securities exchange or the Nasdaq NM (or a similar national quotation system),
then the value shall be deemed to be the average of the closing prices of the
securities on such exchange or system over the 30-day period ending three (3)
days prior to the distribution;

                         (B) if actively traded over-the-counter, then the value
shall be deemed to be the average of the closing bid prices over the 30-day
period ending three (3) days prior to the closing of such merger, consolidation
or sale;

                         (C) if there is no active public market, then the value
shall be the fair market value thereof, as determined in good faith by the
Board: and

                    (ii) The method of valuation of securities subject to
investment letter or other restrictions on free marketability shall be to make
an appropriate discount from the market value determined as above in
subparagraphs (c)(A), (B) or (C) of this Section to reflect the approximate fair
market value thereof, as determined in good faith by the Board.

          4. VOTING RIGHTS. A holder of a share of Series B Stock shall be
entitled to 100 votes for each vote allotted to the holder of one share of
Common Stock on any and all matters including the election of directors and
shall except as may be otherwise provided by law vote as a class with the
holders of outstanding Common Stock.

          5. CONVERSION RIGHTS. The issued and outstanding shares of Series B
Stock shall be convertible into Common Stock as follows:


                                       -3-
<PAGE>

               (a) OPTIONAL CONVERSION.

                    (i) At the option of the holder thereof, each share of
Series B Stock shall be convertible, at any time or from time to time into fully
paid and nonassessable shares of Common Stock as provided herein.

                    (ii) Each holder of Series B Stock who elects to convert the
same into shares of Common Stock shall surrender the certificate or certificates
therefor, duly endorsed, at the office of the Company or any transfer agent for
the Series B Stock or Common Stock, and shall give written notice to the Company
at such office that such holder elects to convert the same and shall state
therein the number of shares of Series B Stock being convened. Thereupon the
Company shall promptly issue and deliver at such office to such holder a
certificate or certificates for the number of shares of Common Stock to which
such holder is entitled upon such conversion. Such conversion shall be deemed to
have been made immediately prior to the close of business on the date of such
surrender of the certificate or certificates representing the shares of Series B
Stock to be converted, and the person entitled to receive the shares of Common
Stock issuable upon such conversion shall be treated for all purposes as the
record holder of such shares of Common Stock on such date.

               (b) CONVERSION RATE. Each share of Series B Stock shall be
convertible in accordance with SECTION 5(a) above into 100 shares of Common
Stock (the "CONVERSION RATE"). The Conversion Rate of the Series B Stock shall
be subject to adjustment from time to time as provided below.

               (c) ADJUSTMENT UPON COMMON STOCK EVENT. Upon the happening of a
Common Stock Event (as hereinafter defined), the Conversion Rate of the Series B
Stock shall, simultaneously with the happening of such Common Stock Event, be
adjusted by multiplying the Conversion Rate of the Series B Stock in effect
immediately prior to such Common Stock Event by a fraction, (i) the numerator of
which shall be the number of shares of Common Stock issued and outstanding
immediately prior to such Common Stock Event, and (ii) the denominator of which
shall be the number of shares of Common Stock issued and outstanding immediately
after such Common Stock Event, and the product so obtained shall thereafter be
the Conversion Rate for such Series B Stock. The Conversion rate for the Series
B Stock shall be readjusted in the same manner upon the happening of each
subsequent Common Stock Event. As used herein, the term "COMMON STOCK EVENT"
shall mean (x) the issue by the Company of additional shares of Common Stock as
a dividend or other distribution on outstanding Common Stock, (y) a subdivision
of the outstanding shares of Common Stock into a greater number of shares of
Common Stock, or (z) a combination of the outstanding shares of Common Stock
into a smaller number of shares of Common Stock.

               (d) ADJUSTMENTS FOR OTHER DIVIDENDS AND DISTRIBUTIONS. If at any
time or from time to time after the Original Issue Date the Company pays a
dividend or makes another distribution to the holders of the Common Stock
payable in securities of the Company other than shares of Common Stock, then in
each such event provision shall be made so that the holders of the Series B
Stock shall receive upon conversion thereof, in addition to the number of shares
of Common Stock receivable upon conversion thereof, the number of securities of
the Company which they would have received had their Series B Stock been
converted into Common Stock on the date of such event (or such record date, as
applicable) and had they

                                       -4-
<PAGE>

thereafter, during the period from the date of such event (or such record date,
as applicable) to and including the conversion date, retained such securities
receivable by them as aforesaid during such period, subject to all other
adjustments called for during such period under this SECTION 5 with respect to
the rights of the holders of the Series B Stock or with respect to such other
securities by their terms.

               (e) ADJUSTMENT FOR RECLASSIFICATION, EXCHANGE AND SUBSTITUTION.
If at any time or from time to time after the Original Issue Date the Common
Stock issuable upon the conversion of the Series B Stock is changed into the
same or a different number of shares of any class or classes of stock, whether
by recapitalization, reclassification or otherwise (OTHER THAN by a Common Stock
Event or a stock dividend, reorganization, merger, consolidation or sale of
assets provided for elsewhere in this Section 5), then in any such event each
holder of Series B Stock shall have the right thereafter to convert such stock
into the kind and amount of stock and other securities and property receivable
upon such recapitalization, reclassification or other change by holders of the
number of shares of Common Stock into which such shares of Series S Stock could
have been converted immediately prior to such recapitalization, reclassification
or change, all subject to further adjustment as provided herein or with respect
to such other securities or property by the terms thereof.

               (f) CERTIFICATE OF ADJUSTMENT. In each case of an adjustment or
readjustment of the Conversion Rate for the Series B Stock, the Company, at its
expense, shall cause its Chief Financial Officer to compute such adjustment or
readjustment in accordance with the provisions hereof and prepare a certificate
showing such adjustment or readjustment, and shall mail such certificate, by
first class mail, postage prepaid, to each record holder of the Series B Stock
at the holder's address as shown in the Company's books.

               (g) FRACTIONAL SHARES. No fractional shares of Common Stock shall
be issued upon any conversion of Series B Stock. In lieu of any fractional share
to which the holder would otherwise be entitled, the Company shall, at the
Company's option: (x) pay the holder cash equal to the product of such fraction
multiplied by the Common Stock's fair market value as determined in good faith
by the Board as of the date of conversion, or (y) round up to the nearest whole
share of Common Stock to be issued upon any such conversion.

               (h) RESERVATION OF STOCK ISSUABLE UPON CONVERSION. The Company
shall at all times reserve and keep available out of its authorized but unissued
shares of Common Stock, solely for the purpose of effecting the conversion of
the shares of the Series B Stock, such number of its shares of Common Stock as
shall from time to time be sufficient to effect the conversion of all
outstanding shares of the Series B Stock; and if at any time the number of
authorized but unissued shares of Common Stock shall not be sufficient to effect
the conversion of all then outstanding shares of the Series B Stock, the Company
will take such corporate action as may, in the opinion of its counsel, be
necessary to increase its authorized but unissued shares of Common Stock to such
number of shares as shall be sufficient for such purpose.


                                      -5-
<PAGE>

               (i) NOTICES. Any notice required by the provisions of this
SECTION 5 to be given to the holders of shares of the Series B Stock shall be
deemed given upon the earlier of actual receipt or deposit in the United States
mail, by certified or registered mail, return receipt requested, postage
prepaid, addressed to each holder of record at the address of such holder
appearing on the books of the Company.

               (j) NO IMPAIRMENT. The Company shall not avoid or seek to avoid
the observance or performance of any of the terms to be observed or performed
hereunder by the Company, but shall at all times in good faith assist in
carrying out all such action as may be reasonably necessary or appropriate in
order to protect the conversion rights of the holders of the Series B Stock
against impairment.

          6. MISCELLANEOUS.

               (a) NO REISSUANCE OF SERIES B STOCK. No share or shares of Series
B Stock acquired by the Company by reason of redemption, purchase, conversion or
otherwise shall be reissued, and all such shares shall be canceled, retired and
eliminated from the shares which the Company shall be authorized to issue.

               (b) CONSENT TO CERTAIN TRANSACTIONS. Each holder of shares of
Series B Stock shall, by virtue of its acceptance of a stock certificate
evidencing Series B Stock, be deemed to have consented, to all Permitted
Repurchases.

provided for in the Articles are represented at a meeting, a majority of the
shares present may adjourn the meeting without further notice for a period which
shall not exceed 60 days. At such adjourned meeting, at which a quorum shall be
present, any business may be transacted which might have been transacted at the

shareholders present may continue to transact business until adjournment,
notwithstanding any departures of shareholders during the meeting which leave

          Section 7. VOTING OF SHARES. Each outstanding share entitled to vote
shall be entitled to one vote upon each matter submitted to a vote at a meeting
of shareholders.

          Section 8. PROXIES. At all meetings of shareholders, a shareholder may
vote by proxy executed in writing by the shareholder or by his duly authorized
attorney-in-fact. Such proxy shall be filed with the secretary of the Company
before or at the time of the meeting. No proxy shall be valid after 11 months
from the date of its execution, unless otherwise provided in the proxy. No
telegraphic proxies shall be valid. No proxies with printed or typed signatures
shall be valid.

          Section 9. VOTING OF SHARES BY CERTAIN HOLDERS. Shares standing in the
name of another corporation may be voted by agent or proxy as the Bylaws of
such corporation may prescribe or, in the absence of such provision, as the
board of directors of such corporation may determine.

majority of the shares entitled to vote for the election of directors of such
other corporation is held by the Company, shall be voted at any meeting or
counted in determining the total number of outstanding shares at any given time.

          Shares held by an administrator, executor, guardian or conservator may
be voted by him, either in person or by proxy, without a transfer of such shares
into his name. Shares standing in the name of a trustee may be voted by him,
either in person or by proxy, but no trustee shall be entitled to vote shares
held by him without a transfer of the shares into his name.

          Shares standing in the name of a receiver may be voted by such
receiver and shares held by or under the control of a receiver may be voted by
such receiver, without the transfer thereof into his name if authority so to do
is contained in an appropriate order of the court by which the receiver was
appointed.

          A shareholder whose shares are pledged shall be entitled to vote such
shares until the shares have been transferred into the name of the pledgee, and
thereafter the pledgee shall be entitled to vote the shares so transferred.

          Section 10. ACTION BY CONSENT OF ALL SHAREHOLDERS. Any action required
to be taken, or which may be taken at a meeting of the shareholders may be taken
without a meeting, if a consent in writing, setting forth the action so taken,
shall be signed by all of the shareholders entitled to vote with respect to the
subject matter thereof. Such written consent or consents shall be filed with the
minutes of the Company. Such action by written consent of all entitled to vote
shall have the same force and effect as a unanimous vote of such shareholders.

shareholders, appoint one or more inspectors to act at such meeting or any
adjournment thereof. If the inspectors shall not be so appointed or if any of
them shall fail to appear or act, the chairman of the meeting may appoint
inspectors. Each inspector, before entering upon the discharge of his duties,
shall take and sign an oath faithfully to execute the duties of inspector at
such meeting with strict impartiality and according to the best of his ability.

power of each, the number of shares represented at the meeting, the existence of

consents, hear and determine all challenges and questions arising in connection
with the right to vote, count and tabulate all votes, ballots or consents,

may be paid their expenses, if any, for attendance at each meeting of the Board
and may be paid a fixed sum for attendance at each meeting of the Board and a

          Section 12. PRESUMPTION OF ASSENT. A director of the Company who is

substantially all of the property and assets of the Company otherwise than in
the usual and regular course of its business, recommending to the shareholders a
voluntary dissolution of the Company or a revocation thereof, or amending the
Bylaws. The designation of such committees and the delegation thereto of
authority shall not operate to relieve the Board, or any member thereof, of any
responsibility imposed by law.

a committee designated in accordance with this Section of the Bylaws, may be
taken without a meeting, if a consent in writing setting forth the action so
taken shall be signed by all those entitled to vote with respect to the subject

          A Certificate signed or impressed with the facsimile signature of an

organized, the name of the person to whom the Securities are issued, the
designation of the series, if any, and the par value of each share represented
by the Certificate, or a statement that the shares are without par value. The
name and address of the person to whom the Securities represented hereby are
issued, the number of Securities, and date of issue, shall be entered on the
Security transfer books of the Company. All Certificates surrendered to the
Company for transfer shall be canceled and no new Certificate shall be issued
until the former Certificate for a like number of shares shall have been
surrendered and canceled, except that, in case of a lost, destroyed or mutilated
Certificate, a new one may be issued therefor upon such terms and indemnity to
the Company as the Board may prescribe.

made only on the security transfer books of the Company by the holder of record
thereof, by his legal representative who shall furnish proper evidence of
authority to transfer, or by his attorney authorized by a power of attorney
which was duly executed and filed with the secretary of the Company and a

be the owner thereof for all purposes.

          Whenever any notice is required to be given to any shareholder or
director of the Company under the provisions of these Bylaws or under the
provisions of the Articles or under the provisions of the applicable laws of the
State of Colorado, a waiver thereof in writing, signed by the person or persons
entitled to such notice, whether before, at or after the time stated therein,

                  UNIFORMITY OF INTERPRETATION AND SEVERABILITY
                  ---------------------------------------------

          These Bylaws shall be so interpreted and construed as to conform to
the Articles and the statutes of the State of Colorado or of any other state in
which conformity may become necessary by reason of the qualification of the
Company to do business in such foreign state, and where conflict between these
Bylaws and the Articles or a statute has arisen or shall arise, the Bylaws shall
be considered to be modified to the extent, but only to the extent, conformity
shall require. If any Bylaw provision or its application shall be deemed invalid
by reason of the said nonconformity, the remainder of the Bylaws shall remain
operable in that the provisions set forth in the Bylaws are severable.

         2.  Tax Consequences.

             2.1. TAX STATUS OF OPTION. This Option is not intended to be an
Incentive Stock Option within the meaning of Section 422(b) of the Code. The
Optionee should consult with the Optionee's own tax advisor regarding the tax
effects of this Option.

             2.2. ELECTION UNDER SECTION 83(b) OF THE CODE. If the Optionee
exercises this Option to purchase shares of Stock that are both nontransferable
and subject to a substantial risk of forfeiture, the Optionee understands that
the Optionee should consult with the Optionee's tax advisor regarding the
advisability of filing with the Internal Revenue Service an election under
Section 83(b) of the Code, which must be filed no later than thirty (30) days
after the date on which the Optionee exercises the Option. Shares acquired upon
exercise of the Option are nontransferable and subject to a substantial risk of
forfeiture if, for example, (a) they are unvested and are subject to a right of
the Company to repurchase such shares at the Optionee's original purchase price
if the Optionee's Service terminates or (b) the Optionee is subject to a
restriction on transfer to comply with "Pooling-of-Interests Accounting" rules.
Failure to file an election under Section 83(b), if appropriate, may result in
adverse tax consequences to the Optionee. The Optionee acknowledges that the
Optionee has been advised to consult with a tax advisor prior to the exercise of
the Option regarding the tax consequences to the Optionee of the exercise of the
Option. AN ELECTION UNDER SECTION 83(b) MUST BE FILED WITHIN 30 DAYS AFTER THE
DATE ON WHICH THE OPTIONEE PURCHASES UNITS. THIS TIME PERIOD CANNOT BE EXTENDED.
THE OPTIONEE ACKNOWLEDGES THAT TIMELY FILING OF A SECTION 83(b) ELECTION IS THE
OPTIONEE'S SOLE RESPONSIBILITY, EVEN IF THE OPTIONEE REQUESTS THE COMPANY OR ITS
REPRESENTATIVE TO FILE SUCH ELECTION ON HIS OR HER BEHALF.

         3.  ADMINISTRATION. All questions of interpretation concerning this
Option Agreement shall be determined by the Board, including any duly appointed
Committee of the Board. All determinations by the Board shall be final and
binding upon all persons having an interest in the Option. Any officer of the
Company shall have the authority to act on behalf of the Company with respect to
any matter, right, obligation, or election which is the responsibility of or
which is allocated to the Company herein, provided the officer has apparent
authority with respect to such matter, right, obligation, or election.

         4.  EXERCISE OF THE OPTION.

             4.1. RIGHT TO EXERCISE. Except as otherwise provided herein, the
Option shall be exercisable on and after the Initial Vesting Date and prior to
the termination of the Option (as provided in Section 6) in an amount not to
exceed the Number of Option Shares multiplied by the Vested Ratio less the
number of shares previously acquired upon exercise of the Option, subject to the
Optionee's agreement that any shares purchased upon exercise are subject to the
Company's repurchase rights set forth in Section 11 and Section 12. In no event
shall the Option be exercisable for more shares than the Number of Option
Shares.

             4.2. METHOD OF EXERCISE. Exercise of the Option shall be by written
notice to the Company which must state the election to exercise the Option, the
number of whole shares for which the Option is being exercised and such other
representations and agreements as to the Optionee's investment intent with
respect to such shares as may be required pursuant to the provisions of this
Option Agreement. The written notice must be signed by the Optionee and must be
delivered in person, by certified or registered mail, return receipt requested,
by confirmed facsimile transmission, or by such other means as the Company may
permit, to the Chief Financial Officer of the Company, or other authorized
representative of the Company, prior to the termination of the Option as set
forth in Section 6, accompanied by full payment of the aggregate Exercise Price
for the number of shares being purchased. The Option shall be deemed to be
exercised upon receipt by the Company of such written notice, the aggregate
Exercise Price, and, if required by the Company, such executed agreement.

                                       3
<PAGE>

             4.3. PAYMENT OF EXERCISE PRICE. Payment of the aggregate Exercise
Price for the number of shares of Stock for which the Option is being exercised
shall be made in cash, by check, or cash equivalent.

             4.4. TAX WITHHOLDING. At the time the Option is exercised, in whole
or in part, or at any time thereafter as requested by the Company, the Optionee
hereby authorizes withholding from payroll and any other amounts payable to the
Optionee, and otherwise agrees to make adequate provision for, any sums required
to satisfy the federal, state, local and foreign tax withholding obligations of
the Company, if any, which arise in connection with the Option, including,
without limitation, obligations arising upon (i) the exercise, in whole or in
part, of the Option, (ii) the transfer, in whole or in part, of any shares
acquired upon exercise of the Option, (iii) the operation of any law or
regulation providing for the imputation of interest, or (iv) the lapsing of any
restriction with respect to any shares acquired upon exercise of the Option. The
Optionee is cautioned that the Option is not exercisable unless the tax
withholding obligations of the Company are satisfied. Accordingly, the Optionee
may not be able to exercise the Option when desired even though the Option is
vested, and the Company shall have no obligation to issue a certificate for such
shares except as provided for herein.

             4.5. CERTIFICATE REGISTRATION. Any certificate for the shares as to
which the Option is exercised shall be registered in the name of the Optionee,
or, if applicable, in the names of the heirs of the Optionee.

             4.6. RESTRICTIONS ON GRANT OF THE OPTION AND ISSUANCE OF SHARES.
The grant of the Option and the issuance of shares of Stock upon exercise of the
Option shall be subject to compliance with all applicable requirements of
federal, state or foreign law with respect to such securities. The Option may
not be exercised if the issuance of shares of Stock upon exercise would
constitute a violation of any applicable federal, state or foreign securities
laws or other law or regulations or the requirements of any stock exchange or
market system upon which the Stock may then be listed. In addition, the Option
may not be exercised unless (i) a registration statement under the Securities
Act shall at the time of exercise of the Option be in effect with respect to the
shares issuable upon exercise of the Option or (ii) in the opinion of legal
counsel to the Company, the shares issuable upon exercise of the Option may be
issued in accordance with the terms of an applicable exemption from the
registration requirements of the Securities Act. THE OPTIONEE IS CAUTIONED THAT
THE OPTION MAY NOT BE EXERCISED UNLESS THE FOREGOING CONDITIONS ARE SATISFIED.
ACCORDINGLY, THE OPTIONEE MAY NOT BE ABLE TO EXERCISE THE OPTION WHEN DESIRED
EVEN THOUGH THE OPTION IS VESTED. The inability of the Company to obtain from
any regulatory body having jurisdiction the authority, if any, deemed by the
Company's legal counsel to be necessary to the lawful issuance and sale of any
shares subject to the Option shall relieve the Company of any liability in
respect of the failure to issue or sell such shares as to which such requisite
authority shall not have been obtained. As a condition to the exercise of the
Option, the Company may require the Optionee to satisfy any qualifications that
may be necessary or appropriate, to evidence compliance with any applicable law
or regulation and to make any representation or warranty with respect thereto as
may be requested by the Company.

             4.7. FRACTIONAL SHARES. The Company shall not be required to issue
fractional shares upon the exercise of the Option.

         5.  NONTRANSFERABILITY OF THE OPTION. The Option may be exercised
during the lifetime of the Optionee only by the Optionee or the Optionee's
guardian or legal representative and may not be assigned or transferred in any
manner except by will or by the laws of descent and distribution. Following the
death of the Optionee, the Option, to the extent provided in Section 7, may be
exercised by the Optionee's legal representative or by any person empowered to
do so under the deceased Optionee's will or under the then applicable laws of
descent and distribution.

                                       4

         6.  TERMINATION OF THE OPTION. The Option shall terminate and may no
longer be exercised on the first to occur of (a) the Option Expiration Date, (b)
the last date for exercising the Option following termination of the Optionee's
Service as described in Section 7, or (c) a transfer of control to the extent
provided in Section 8.

         7.  EFFECT OF TERMINATION OF SERVICE.

             7.1. OPTION EXERCISABILITY.

                  (a) DISABILITY. If the Optionee's Service with the Company is
terminated because of the Disability of the Optionee, the Option, to the extent
unexercised and exercisable on the date on which the Optionee's Service
terminated, may be exercised by the Optionee (or the Optionee's guardian or
legal representative) at any time prior to the expiration of twelve months after
the date on which the Optionee's Service terminated, but in any event no later
than the Option Expiration Date.

                  (b) DEATH. If the Optionee's Service with the Company is
terminated because of the death of the Optionee, the Option, to the extent
unexercised and exercisable on the date on which the Optionee's Service
terminated, may be exercised by the Optionee (or the Optionee's legal
representative or other person who acquired the right to exercise the Option by
reason of the Optionee's death) at any time prior to the expiration of twelve
months after the date on which the Optionee's Service terminated, but in any
event no later than the Option Expiration Date.

                  (c) OTHER TERMINATION OF SERVICE. If the Optionee's Service
with the Company terminates for any reason, except Disability or death, the
Option, to the extent unexercised and exercisable by the Optionee on the date on
which the Optionee's Service terminated, may be exercised by the Optionee within
three months after the date on which the Optionee's Service terminated, but in
any event no later than the Option Expiration Date.

             7.2. EXTENSION IF EXERCISE PREVENTED BY LAW. Notwithstanding the
foregoing, if the exercise of the Option within the applicable time periods set
forth in Section 7.1 is prevented by the provisions of Section 4.6, the Option
shall remain exercisable until three months after the date the Optionee is
notified by the Company that the Option is exercisable, but in any event no
later than the Option Expiration Date.

             7.3. LEAVE OF ABSENCE. For purposes of Section 7.1, the Optionee's
Service with the Company shall not be deemed to terminate if the Optionee takes
any military leave, sick leave, or other bona fide leave of absence approved by
the Company of ninety (90) days or less. In the event of a leave of absence in
excess of ninety (90) days, the Optionee's Service shall be deemed to terminate
on the ninety-first (91st) day of such leave unless the Optionee's right to
re-employment with the Company remains guaranteed by statute or contract.

         8.  ADJUSTMENTS.

             8.4. ADJUSTMENTS IN OPTION. Subject to Section 8.2, in the event
that the outstanding shares of the common stock are changed into or exchanged
for a different number or kind of shares of the Company or other securities of
the Company or a successor entity by reason of merger, consolidation, corporate
reorganization, recapitalization, reclassification, stock split-up, stock
dividend, combination of shares, or otherwise, the board, or the governing body
of any successor entity, shall make an appropriate and equitable adjustment in
the number and kind of Option Shares as to which the Option is then unexercised
in order that, after such event, the Option Shares as to which the Option is
then unexercised shall represent the same potential ownership interest in the
Company (or that part of a successor entity which consists of the Company)
immediately after such event as they represent immediately before such event.
The adjustment shall be made without change in the total price applicable to any
then unexercised portion of the Option (except for any change in the aggregate
price resulting from rounding-off of share quantities or prices) and with any
necessary corresponding adjustment in the purchase price per share. In no event
shall the Option Shares include any fractional share or other security but any
fractions resulting from any adjustment shall be rounded to the nearest whole
share. Any adjustment by the board or governing body shall be conclusive and
shall bind the Optionee, the Company, any successor entity, and any other
interested persons.

                                       5
<PAGE>

             8.2. ACCELERATION OF EXERCISABILITY. In the event of any merger or
consolidation of the Company into another corporation, exchange of all or
substantially all of the assets of the company for the securities of another
corporation, acquisition by another corporation of fifty percent (50%) or more
of the Company's then outstanding voting stock, or liquidation or dissolution of
the Company ("transfer of control"), the board, or the governing body of any
successor entity, shall either make the adjustment contemplated by Section 8.1
or provide, on such terms and conditions as it deems appropriate, that at some
time prior to the effective date of such event, the Option shall become
exercisable as to all Option Shares, notwithstanding that the Option may not yet
have become fully exercisable under Section 4.1. At least ten (10) days prior to
the effective date of merger, consolidation, exchange, acquisition, liquidation,
or dissolution, the Company or successor entity shall give the Optionee notice
of such event, advising the Optionee of the Board's or Committee's determination
under this Section 8.2. The Board or Committee may make such determinations and
adopt such rules and conditions as it, in its absolute discretion, deems
appropriate in connection with any adjustment pursuant to Section 8.1 or
acceleration of exercisability under this Section 8.2, including, but not by way
of limitation, provisions to insure that any adjustment or acceleration shall be
conditioned on the consummation of the contemplated corporate transaction.


         9.  RIGHTS AS A SHAREHOLDER, EMPLOYEE OR CONSULTANT. The Optionee shall
have no rights as a shareholder with respect to any shares covered by the Option
until the date of the issuance of a certificate for the shares for which the
Option has been exercised (as evidenced by the appropriate entry on the books of
the Company or of a duly authorized transfer agent of the Company). No
adjustment shall be made for dividends, distributions or other rights for which
the record date is prior to the date of such exercise, except as provided in
Section 8. Nothing in this Option Agreement shall confer upon the Optionee any
right to continue in the Service of the Company or interfere in any way with any
right of the Company to terminate the Optionee's Service as an Employee or
Consultant, as the case may be, at any time.

         10. RIGHT OF FIRST REFUSAL. The following right of first refusal is in
addition to any transfer restrictions that may exist by reason of the Articles
of Incorporation or Bylaws of the Company.

             10.5. GRANT OF RIGHT OF FIRST REFUSAL. Except as provided in
Section 11.7 below, in the event the Optionee, the Optionee's legal
representative, or other holder of shares acquired upon exercise of the Option
proposes to sell, exchange, transfer, pledge, or otherwise dispose of any shares
acquired upon exercise of the Option (the "TRANSFER SHARES") to any person or
entity, including, without limitation, any shareholder of the Company, the
Company shall have the right to repurchase the Transfer Shares under the terms
and subject to the conditions set forth in this Section 11 (the "RIGHT OF FIRST
REFUSAL").

             10.6. NOTICE OF PROPOSED TRANSFER. Prior to any proposed transfer
of the Transfer Shares, the Optionee shall give a written notice (the "TRANSFER
NOTICE") to the Company describing fully the proposed transfer, including the
number of Transfer Shares, the name and address of the proposed transferee (the
"PROPOSED TRANSFEREE") and, if the transfer is voluntary, the proposed transfer
price, and containing such information necessary to show the bona fide nature of
the proposed transfer. In the event of a bona fide gift or involuntary transfer,
the proposed transfer price shall be deemed to be the Fair Market Value of the
Transfer Shares, as determined by the Board in good faith. If the Optionee
proposes to transfer any Transfer Shares to more than one Proposed Transferee,
the Optionee shall provide a separate Transfer Notice for the proposed transfer
to each Proposed Transferee. The Transfer Notice shall be signed by both the
Optionee and the Proposed Transferee and must constitute a binding commitment of
the Optionee and the Proposed Transferee for the transfer of the Transfer Shares
to the Proposed Transferee subject only to the Right of First Refusal.

                                       6
<PAGE>

             10.7. BONA FIDE TRANSFER. If the Company determines that the
information provided by the Optionee in the Transfer Notice is insufficient to
establish the bona fide nature of a proposed voluntary transfer, the Company
shall give the Optionee written notice of the Optionee's failure to comply with
the procedure described in this Section 11, and the Optionee shall have no right
to transfer the Transfer Shares without first complying with the procedure
described in this Section 11. The Optionee shall not be permitted to transfer
the Transfer Shares if the proposed transfer is not bona fide.

             10.8. EXERCISE OF RIGHT OF FIRST REFUSAL. If the Company determines
the proposed transfer to be bona fide, the Company shall have the right to
purchase all, but not less than all, of the Transfer Shares (except as the
Company and the Optionee otherwise agree) at the purchase price and on the terms
set forth in the Transfer Notice by delivery to the Optionee of a notice of
exercise of the Right of First Refusal within thirty (30) days after the date
the Transfer Notice is delivered to the Company. The Company's exercise or
failure to exercise the Right of First Refusal with respect to any proposed
transfer described in a Transfer Notice shall not affect the Company's right to
exercise the Right of First Refusal with respect to any proposed transfer
described in any other Transfer Notice, whether or not such other Transfer
Notice is issued by the Optionee or issued by a person other than the Optionee
with respect to a proposed transfer to the same Proposed Transferee. If the
Company exercises the Right of First Refusal, the Company and the Optionee shall
thereupon consummate the sale of the Transfer Shares to the Company on the terms
set forth in the Transfer Notice within sixty (60) days after the date the
Transfer Notice is delivered to the Company (unless a longer period is offered
by the Proposed Transferee). In the event the Transfer Notice provides for the
payment for the Transfer Shares other than in cash, the Company shall have the
option of paying for the Transfer Shares by the present value cash equivalent of
the consideration described in the Transfer Notice. For purposes of the
foregoing, cancellation of any indebtedness of the Optionee to the Company shall
be treated as payment to the Optionee in cash to the extent of the unpaid
principal and any accrued interest canceled.

             10.9. FAILURE TO EXERCISE RIGHT OF FIRST REFUSAL. If the Company
fails to exercise the Right of First Refusal in full (or to such lesser extent
as the Company and the Optionee otherwise agree) within the period specified in
Section 11.4 above, the Optionee may conclude a transfer to the Proposed
Transferee of the Transfer Shares on the terms and conditions described in the
Transfer Notice, provided such transfer occurs not later than six months
following delivery to the Company of the Transfer Notice. The Company shall have
the right to demand further assurances from the Optionee and the Proposed
Transferee (in a form satisfactory to the Company) that the transfer of the
Transfer Shares was actually carried out on the terms and conditions described
in the Transfer Notice. No Transfer Shares shall be transferred on the books of
the Company until the Company has received such assurances, if so demanded, and
has approved the proposed transfer as bona fide. Any proposed transfer on terms
and conditions different from those described in the Transfer Notice, as well as
any subsequent proposed transfer by the Optionee, shall again be subject to the
Right of First Refusal and shall require compliance by the Optionee with the
procedure described in this Section 11.

             10.10. TRANSFEREES OF TRANSFER SHARES. All transferees of the
Transfer Shares or any interest therein, other than the Company, shall be
required as a condition of such transfer to agree in writing (in a form
satisfactory to the Company) that such transferee shall receive and hold such
Transfer Shares or interest therein subject to all of the terms and conditions
of this Option Agreement, including this Section 11 providing for the Right of
First Refusal with respect to any subsequent transfer. Any sale or transfer of
any shares acquired upon exercise of the Option shall be void unless the
provisions of this Section 11 are met.

                                       7
<PAGE>

             10.11. TRANSFERS NOT SUBJECT TO RIGHT OF FIRST REFUSAL. The Right
of First Refusal shall not apply to any transfer or exchange of the shares
acquired upon exercise of the Option if such transfer or exchange is in
connection with an Ownership Change Event. If the consideration received
pursuant to such transfer or exchange consists of stock of the Company, such
consideration shall remain subject to the Right of First Refusal unless the
provisions of Section 11.9 below result in a termination of the Right of First
Refusal.

             10.12. ASSIGNMENT OF RIGHT OF FIRST REFUSAL. The Company shall have
the right to assign the Right of First Refusal at any time, whether or not there
has been an attempted transfer, to one or more persons as may be selected by the
Company.

             10.13. EARLY TERMINATION OF RIGHT OF FIRST REFUSAL. The other
provisions of this Option Agreement notwithstanding, the Right of First Refusal
shall terminate and be of no further force and effect upon (a) the occurrence of
a transfer of control, unless the successor entity assumes the Company's rights
and obligations under the Option or substitutes a substantially equivalent
option for the successor entity's stock for the Option, or (b) the existence of
a public market for the class of shares subject to the Right of First Refusal. A
"PUBLIC MARKET" shall be deemed to exist if (i) such stock is listed on a
national securities exchange (as that term is used in the Exchange Act) or (ii)
such stock is traded on the over-the-counter market and prices therefor are
published daily on business days in a recognized financial journal.

         11. SHARE REPURCHASE OPTION.

             11.14. GRANT OF REPURCHASE OPTION. Except as provided in Section
12.4 below, in the event of the occurrence of any Repurchase Event, as defined
below, the Company shall have the right to repurchase the shares acquired by the
Optionee pursuant to the Option (the "REPURCHASE SHARES") under the terms and
subject to the conditions set forth in this Section 12 (the "SHARE REPURCHASE
OPTION"). Each of the following events shall constitute a "REPURCHASE EVENT":

                  (a) Termination of the Optionee's Service with the Company for
any reason or no reason, with or without cause, including death or Disability.
The Repurchase Period, as defined below, shall commence on the date of
termination of the Optionee's Service.

                  (b) The Optionee, the Optionee's legal representative, or
other holder of shares acquired upon exercise of the Option attempts to sell,
exchange, transfer, pledge, or otherwise dispose of any Repurchase Shares
without complying with the provisions of Section 11. The Repurchase Period, as
defined below, shall commence on the date the Company receives actual notice of
such attempted sale, exchange, transfer, pledge or other disposition.

                  (c) The receivership, bankruptcy or other creditor's
proceeding regarding the Optionee or the taking of any of the Optionee's Shares
by legal process, such as a levy of execution. The Repurchase Period, as defined
below, shall commence on the date the Company receives actual notice of the
commencement of pendency of the receivership, bankruptcy or other creditor's
proceeding or the date of such taking, as the case may be. The Fair Market Value
of the Repurchase Shares shall be determined as of the last day of the month
preceding the month in which the proceeding involved commenced or the taking
occurred.

             11.15. EXERCISE OF SHARE REPURCHASE OPTION. The Company may
exercise the Share Repurchase Option by written notice to the Optionee, the
Optionee's legal representative, or other holder of the Repurchase Shares, as
the case may be, during the Repurchase Period. The "REPURCHASE PERIOD" shall be
the period commencing at the time set forth in Section 12.1 above and ending on
the later of (a) the date ninety (90) days after the commencement of the
Repurchase Period or (b) the date ninety (90) days after the Option is last
exercised. If the Company fails to give notice during the Repurchase Period, the
Share Repurchase Option shall terminate (unless the Company and the Optionee
have extended the time for the exercise of the Share Repurchase Option) unless
and until there is a subsequent Repurchase Event. Notwithstanding a termination
of the Share Repurchase Option, the remaining provisions of this Option
Agreement shall remain in full force and effect, including, without limitation,
the Right of First Refusal set forth in Section 11. If there is a subsequent
Repurchase Event, the Share Repurchase Option shall again become exercisable as
provided in this Section 12. The Share Repurchase Option must be exercised, if
at all, for all of the Repurchase Shares, except as the Company and the Optionee
otherwise agree.

             11.16. PAYMENT FOR REPURCHASE SHARES. In the event of a voluntary
termination of employment by the Optionee or a termination "for cause" by the
Company, the repurchase price per share being repurchased by the Company
pursuant to the Share Repurchase Option shall be an amount equal to the LESSER
of (a) the Optionee's original cost per share, as adjusted pursuant to Section
8.1, or (b) the Fair Market Value of the shares determined as of the date of the
Repurchase Event (except as otherwise provided in Section 12.1(c) above) by the
Board in good faith. In the event of any other Repurchase Event, the repurchase
price per share being repurchased by the Company pursuant to the Share
Repurchase Option shall be an amount equal to the GREATER of the amounts set
forth in clause (a) or (b) from the preceding sentence. Payment by the Company
to the Optionee shall be made in cash on or before the last day of the
Repurchase Period, except that if the total payment due is in excess of $25,000,
the Company may elect to pay the repurchase price by delivery of a promissory
note payable in four equal annual installments, the first due on or before the
last day of the Repurchase Period, with interest payable at the prime rate of
interest on the date of the Repurchase Event. For purpose of the foregoing,
cancellation of any indebtedness of the Optionee to the Company shall be treated
as payment to the Optionee in cash to the extent of the unpaid principal and any
accrued interest canceled. For purposes of this paragraph, "for cause" shall
mean termination by reason of (i) conviction of a felony, (ii) repeated
inattention to the Optionee's responsibilities as an employee following written
notice from the Company and a reasonable time to cure such problems, or (iii)
willful breach of any of the employee's confidentiality obligations.

             11.17. TRANSFERS NOT SUBJECT TO SHARE REPURCHASE OPTION. The Share
Repurchase Option shall not apply to any transfer or exchange of shares acquired
upon exercise of the Option if such transfer or exchange is in connection with
an Ownership Change Event. If the consideration received pursuant to such
transfer or exchange consists of stock of the Company, such consideration will
remain subject to the Share Repurchase Option unless the provisions of Section
12.6 below result in a termination of the Share Repurchase Option.

             11.18. ASSIGNMENT OF SHARE REPURCHASE OPTION. The Company shall
have the right to assign the Share Repurchase Option at any time, whether or not
such option is then exercisable, to one or more persons as may be selected by
the Company.

             11.19. EARLY TERMINATION OF SHARE REPURCHASE OPTION. The other
provisions of this Option Agreement notwithstanding, the Share Repurchase Option
shall terminate and be of no further force and effect upon (a) the occurrence of
a transfer of control, unless the successor entity assumes the Company's rights
and obligations under the Option or substitutes a substantially equivalent
option for the successor entity's stock for the Option, or (b) the existence of
a public market, as defined in Section 11.9, for the securities subject to the
Share Repurchase Option.

         12. DISTRIBUTIONS SUBJECT TO OPTION AGREEMENT. If, from time to time,
there is any stock dividend, stock split or other change, as described in
Section 8.1, in the character or amount of any of the outstanding stock or
ownership interests of the entity which is subject to the provisions of this
Option Agreement, then in such event any and all new, substituted or additional
securities to which the Optionee is entitled by reason of the Optionee's
ownership of the shares acquired upon exercise of the Option shall be
immediately subject to the Right of First Refusal and the Share Repurchase
Option with the same force and effect as the shares subject to the Right of
First Refusal and the Share Repurchase Option immediately before such event.

         13. LEGENDS. The Company may at any time place legends referencing the
Right of First Refusal, the Share Repurchase Option and any applicable federal,
state or foreign securities law restrictions on all certificates representing
shares subject to the provisions of this Option Agreement. The Optionee shall,

EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT."

             13.21. "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A
RIGHT OF FIRST REFUSAL OPTION IN FAVOR OF THE CORPORATION OR ITS ASSIGNEE SET
FORTH IN AN AGREEMENT BETWEEN THE CORPORATION AND THE REGISTERED HOLDER, OR SUCH
HOLDER'S PREDECESSOR IN INTEREST, A COPY OF WHICH IS ON FILE AT THE PRINCIPAL

         14. PUBLIC OFFERING. The Optionee hereby agrees that in the event of
any underwritten public offering of stock, including an initial public offering
of stock, made by the Company pursuant to an effective registration statement
filed under the Securities Act, the Optionee shall not offer, sell, contract to
sell, pledge, hypothecate, grant any option to purchase or make any short sale
of, or otherwise dispose of any shares of stock of the Company or any rights to
acquire stock of the Company for such period of time from and after the

The foregoing limitation shall not apply to shares registered in the public
offering under the Securities Act. The Optionee shall be subject to this Section
provided and only if the officers and directors of the Company are also subject
to similar arrangements.

                      Attachment I: Stock Option Agreement


                                 SPACEDEV, INC.

                             STOCK OPTION AGREEMENT

         Pursuant to the Grant Notice and this Stock Option Agreement, the
Company has granted you an option to purchase the number of shares of the
Company's common stock ("Common Stock") indicated in the Grant Notice at the
exercise price indicated in the Grant Notice. Defined terms not explicitly
defined in this Stock Option Agreement but defined in the Plan shall have the
same definitions as in the Plan.

         The details of this option are as follows:

         1. VESTING. Subject to the limitations contained herein, this option
will vest as provided in the Grant Notice, provided that vesting will cease upon
the termination of your Continuous Service.

         2. METHOD OF PAYMENT. Payment of the exercise price by cash (or check)
is due upon exercise of all or any part of this option which has become
exercisable by you. Notwithstanding the foregoing, this option may be exercised
pursuant to a program developed under Regulation T as promulgated by the Federal
Reserve Board which, prior to the issuance of Common Stock, results in either
the receipt of cash (or check) by the Company or the receipt of irrevocable
instructions to pay the aggregate exercise price to the Company. Payment of the
exercise price may also be made by a combination of the above methods.

         3. EXERCISE FOR MINIMUM NUMBER OF SHARES. The minimum number of shares
with respect to which this option may be exercised at any one time is one
hundred (100), except (a) as to an installment subject to exercise, as set forth
in paragraph 1, which amounts to fewer than one hundred (100) shares, in which
case, as to the exercise of that installment, the number of such shares in such
installment shall be the minimum number of shares, and (b) with respect to the
final exercise of this option, this minimum shall not apply. This option may
only be exercised for whole shares.

         4. SECURITIES LAW COMPLIANCE. Notwithstanding anything to the contrary
contained herein, this option may not be exercised unless the shares issuable
upon exercise of this option are then registered under the Securities Act or, if
such shares are not then so registered, the Company has determined that such
exercise and issuance would be exempt from the registration requirements of the
Securities Act.

         5. TERM.

         (a) The term of this option commences on the Date of Grant (as
specified in the Grant Notice) and expires upon the earliest of:

             (i) the Expiration Date indicated in the Grant Notice;

             (ii) the tenth (10th) anniversary of the Date of Grant; or

             (iii) ninety (90) days after the termination of your Continuous
Service for any reason other than Disability or death, provided that if during
any part of such ninety (90) day period the option is not exercisable solely
because of the condition set forth in paragraph 4 (Securities Law Compliance),

                                       2
<PAGE>

in which event the option shall not expire until the earlier of the Expiration
Date or until it shall have been exercisable for an aggregate period of ninety
(90) days after the termination of Continuous Service.

         (b) Notwithstanding the foregoing:

             (i) If your Continuous Service terminates due to your Disability,
then this option will continue to the extent of vested by unexercised options
options for a period of twelve (12) months after the date such service was
terminated, but no later than the Expiration Date.

             (ii) If your Continuous Service terminates due to (x) your death,
or (y) your Disability and you subsequently die prior to the Expiration Date,
then this option shall immediately become fully vested and exercisable for all
of the option shares as of the date of your death. This option will then expire
on the earlier occurring of either the Expiration Date or twelve (12) months
after the date of your death.

         (c) If this option is designated an incentive stock option, then to
obtain the federal income tax advantages associated with an "incentive stock
option," the Code requires that at all times beginning on the Date of Grant and
ending on the day three (3) months before the date of exercise, you must be an
employee of the Company or a "parent corporation" or a "subsidiary corporation"
(as those terms are defined in Section 424 of the Code), except in the event of
your death or your Disability. The Company has provided for extended
exercisability of this option under certain circumstances for your benefit, but
does not represent or guarantee that this option will necessarily be treated as
an "incentive stock option."

         6. EXERCISE.

         (a) You may exercise the vested portion of this option during its term
by delivering a notice of exercise (in a form designated by the Company)
together with the exercise price to the Secretary of the Company, or to such
other person as the Company may designate, during regular business hours,
together with such additional documents as the Company may then require pursuant
to the Plan.

         (b) By exercising this option you agree that as a condition to any
exercise of this option, the Company may require you to enter an arrangement
providing for the payment by you to the Company of any tax withholding
obligation of the Company arising by reason of (1) the exercise of this option;
(2) the lapse of any substantial risk of forfeiture to which the shares are
subject at the time of exercise; or (3) the disposition of shares acquired upon
such exercise.

         (c) If this option is an incentive stock option, then by exercising
this option you agree to notify the Company in writing within fifteen (15) days
after the date of any disposition of any of the shares of the Common Stock
issued upon exercise of this option that occurs within two (2) years after the
Date of Grant or within one (1) year after such shares of Common Stock are
transferred upon exercise of this option.

         7. TRANSFERABILITY. This option is not transferable, except by will or
by the laws of descent and distribution or pursuant to a domestic relations
order as defined by the Code or Title I of the Employee Retirement Income
Securities Act of 1974, as amended (a "DRO"), or the rules thereunder, and is
exercisable during your life only by you or any transferee pursuant to a DRO.

         8. OPTION NOT A SERVICE CONTRACT. This option is not an employment or
service contract and nothing in this option shall be deemed to create in any way
whatsoever any obligation on your part to continue in the service of the Company
or an Affiliate, or of the Company or an Affiliate to continue your service with
the Company or the Affiliate. In addition, nothing in this option shall obligate

                                       3
<PAGE>

the Company or any Affiliates, their stockholders, Board of Directors, Officers
or Employees to continue any relationship as a Director or Consultant for the
Company or any Affiliate.

         9. NOTICES. Any notices provided for in this option or the Plan shall
be given in writing and shall be deemed effectively given upon receipt or, in
the case of notices delivered by the Company to you, five (5) days after deposit
in the United States mail, postage prepaid, addressed to you at the last address
you provided to the Company.

         10. GOVERNING PLAN DOCUMENT. This option is subject to all the
provisions of the Plan, the provisions of which are hereby made a part of this
option, and is further subject to all interpretations, amendments, rules and
regulations which may from time to time be promulgated and adopted pursuant to
the Plan. In the event of any conflict between the provisions of this option and
those of the Plan, the provisions of the Plan shall control.

THE SHARES OF COMMON STOCK ISSUABLE UPON EXERCISE HEREOF HAVE NOT BEEN

Warrant No. RPW-____

                      Original Issue Date: _________, 1999

         THIS CERTIFIES THAT, if the average share price of the common stock,
par value $.0001 (the "COMMON STOCK") of SpaceDev, Inc., a Colorado corporation
(the "COMPANY"), for the 150-day period immediately following the Original Issue
Date hereof is less than the purchase price per share (the "VESTING DATE"), the
person stated below (the "HOLDER"), for value received, is entitled to purchase,
on the terms and conditions hereinafter set forth, at any time or from time to
time during the Exercise Period, but not thereafter, a number of shares of the
Common Stock determined in accordance with Section 2 hereof, at a price per
share equal to the purchase price of $_______ less the average market price, as
defined below, divided by the average market price and multiplied by the number
of shares of Common Stock purchased (the "EXERCISE PRICE"). Each share of Common
Stock as to which this Repricing Warrant is exercisable is a "REPRICING SHARE"
and all such shares are collectively referred to as the "REPRICING SHARES." This
Repricing Warrant shall remain attached to the shares of Common Stock issued to
Holder on the Original Issue Date (the "PURCHASED COMMON SHARES"), until
exercise of this Repricing Warrant, at which time it shall automatically detach.

         SECTION 1. DEFINITIONS. The following capitalized terms are not defined
elsewhere in this Repricing Warrant, and are used herein with the meanings
thereafter ascribed:

              "AVERAGE MARKET PRICE" means the greater of (i) the average
Closing Bid Price of the Common Stock for the ten trading days immediately prior
to the exercise of this Repricing Warrant or (ii) $1.25.

Common Stock on the NASDAQ National Market (the "NASDAQ-NM") as reported by
Bloomberg Financial Markets ("BLOOMBERG"), or, if the NASDAQ-NM is not the
principal trading market for the Common Stock, the last closing bid price of the
Common Stock on the principal securities exchange or trading market where the
Common Stock is listed or traded as reported by Bloomberg, or if the foregoing
do not apply, the last closing bid price of the Common Stock in the
over-the-counter market on the pink sheets or bulletin board for the Common
Stock as reported by Bloomberg, or, if no closing bid price is reported for the
Common Stock by Bloomberg, the last closing trade price of the Common Stock as
reported by Bloomberg. If the Closing Bid Price cannot be calculated for the
Common Stock on such date on any of the foregoing bases, the Closing Bid Price
of the Common Stock on such date shall be the fair market value as reasonably
determined in good faith by the Board of Directors of the Company (all as
appropriately adjusted for any stock dividend, stock split, or other similar
transaction during such period);

                                        1

         SECTION 2. DETERMINATION OF NUMBER OF REPRICING SHARES. The number of
Repricing Shares issuable upon exercise of this Repricing Warrant shall be
determined on the Repricing Date. The number of Repricing Shares shall be equal
to: the number of Purchased Common Shares MULTIPLIED BY a fraction, (a) the
numerator of which is the Repricing Price MINUS the Average Market Price and (b)
the denominator of which is the Average Market Price. In the case of a dispute
as to the determination of the Average Market Price or the arithmetic
calculation of the Exercise Price, the Company shall promptly issue to such
Holder(s) the number of shares of Common Stock that is not disputed and shall
submit the disputed determinations or arithmetic calculations to the holder via
facsimile within three (3) business days of receipt of such holder's Conversion
Notice. If such Holder(s) and the Company are unable to agree upon the
determination of the Average Market Price or arithmetic calculation of the
Exercise Price within two (2) business days of such disputed determination or
arithmetic calculation being submitted to the Holder, then the Company shall
within one (1) business day submit via facsimile (A) the disputed determination
of the Average Market Price to an independent, reputable investment bank or (B)

                   (b) This Warrant may, at the option of the Holder, be
         converted into Common Stock in whole but not in part, if and only if
         the value of one share of Common Stock on the Effective Date (as
         defined in Section 3(c) hereof) is greater than the Exercise Price, by
         delivery to the Company at the address designated in Section 3(a) above
         or to any transfer agent for the Common Stock, on or before 5:00 p.m.
         Eastern Time on the Expiration Date, (i) a written notice of Holder's
         election to convert this Warrant (the "CONVERSION NOTICE"), properly
         executed and completed by the registered Holder or an authorized
         officer thereof, AND (ii) this Repricing Warrant (the items specified
         in (i) and (ii) are collectively the "CONVERSION MATERIALS"). The
         number of shares of Common Stock issuable upon conversion of this
         Repricing Warrant is equal to the quotient of (x) the product of the
         number of Repricing Shares then issuable upon exercise of this Warrant
         (assuming an exercise for cash) MULTIPLIED BY the difference between
         (A) the Average Market Price MINUS (B) the then effective Exercise
         Price DIVIDED BY (C) the Average Market Price. Any fraction resulting
         from the calculation of the number of Repricing Shares then issuable in
         a conversion of this Repricing Warrant shall be truncated.

                   (c) Upon timely receipt of the Exercise Materials or
         Conversion Materials (whichever is applicable), the Company shall, as
         promptly as practicable, and in any event within five (5) business days
         after its receipt of the Exercise Materials or Conversion Materials,
         execute or cause to be executed and delivered to Holder a certificate
         or certificates representing the number of Repricing Shares specified
         in the Exercise Notice or if Holder delivered a Conversion Notice, the
         number of shares of Common Stock issuable upon conversion of this
         Warrant (whichever is applicable), together with cash in lieu of any
         fraction of a share, and, (x) if the Warrant is exercised in full, a
         copy of this Warrant marked "Exercised," or (y) if the Warrant is
         partially exercised, a copy of this Warrant marked "Partially
         Exercised" together with a new Warrant on the same terms for the
         unexercised balance of the Repricing Shares, or (z) if the Warrant is
         converted, a copy of this Warrant marked "Converted." The stock
         certificate or certificates shall be registered in the name of the
         registered Holder of this Warrant or such other name or names as shall
         be designated in the Exercise Notice or Conversion Notice. The date on
         which the Warrant shall be deemed to have been exercised or converted
         (the "EFFECTIVE DATE"), and the date the person in whose name any
         certificate evidencing the Common Stock issued upon the exercise or
         conversion hereof is issued shall be deemed to have become the Holder
         of record of such shares, shall be the date the Corporation receives
         the Exercise Materials or Conversion Materials, irrespective of the
         date of delivery of a certificate or certificates evidencing the Common
         Stock issued upon the exercise or conversion hereof, except that, if
         the date on which the Exercise Materials or Conversion Materials are
         received by the Company is a date on which the stock transfer books of
         the Company are closed, the Effective Date shall be the date the
         Company receives the Exercise Materials or Conversion Materials, and
         the date such person shall be deemed to have become the holder of the
         Common Stock issued upon the exercise or conversion hereof shall be the
         next succeeding date on which the stock transfer books are open. All
         shares of Common Stock issued upon the exercise or conversion of this
         Warrant will, upon issuance, be fully paid and nonassessable and free
         from all taxes, liens, and charges with respect thereto.

                   (d) If the Company shall fail to issue to Holder within five
         (5) business days following the date of receipt by the Company or the
         Transfer Agent of the Exercise Materials or the Conversion Materials, a
         certificate for the number of shares of Common Stock to which such
         holder is entitled upon such holder's exercise or conversion of this
         Warrant, in addition to all other available remedies which such holder
         may pursue hereunder and under this Warrant and the Purchase Agreement
         between the Company and the initial holder of the Warrant (the
         "PURCHASE AGREEMENT") including indemnification pursuant to Section 7
         thereof, the Company shall pay additional damages to such Holder on
         each day after the Effective Date, an amount equal to 1.0% of the
         product of (A) the number of Repricing Shares not issued to Holder and
         to which Holder is entitled MULTIPLIED BY (B) the Closing Bid Price of
         the Common Stock on the Effective Date. Such damages shall be computed
         daily and are due and payable daily.

                                        3
<PAGE>

                   (e) The Company may, in lieu of issuing the Repricing Shares,
         pay Holder an amount equal to the number of Repricing Shares issuable
         on the Effective Date (assuming an exercise for cash) MULTIPLIED BY the
         Average Market Price (the "PAYMENT AMOUNT"). In such event, the Company
         shall be obligated to provide notice to Holder of its intention to pay
         the Payment Amount, and must deliver the Payment Amount to Holder
         within seven (7) business days following the Effective Date. If the
         Company shall fail to deliver the Payment Amount within seven (7)
         business days after the Effective Date, in addition to all other
         available remedies which Holder may pursue at law or equity, including
         indemnification pursuant to Section 7 of the Purchase Agreement, the
         Company shall pay additional damages to Holder on each day after the
         Effective Date, until the Payment Amount has been paid, in an amount
         equal to one percent (1.0%) of the Payment Amount. Such damages shall
         be computed daily and are due and payable daily.

         SECTION 4. ADJUSTMENTS TO REPRICING SHARES. The number of Repricing
Shares issuable upon the exercise hereof shall be subject to adjustment as
follows:

                   (a) In the event the Company is a party to a consolidation,
         share exchange, or merger, or the sale of all or substantially all of
         the assets of the Company to any person, or in the case of any
         consolidation or merger of another corporation into the Company in
         which the Company is the surviving corporation, and in which there is a
         reclassification or change of the shares of Common Stock of the
         Company, this Warrant shall after such consolidation, share exchange,
         merger, or sale be exercisable for the kind and number of securities or
         amount and kind of property of the Company or the corporation or other
         entity resulting from such share exchange, merger, or consolidation, or
         to which such sale shall be made, as the case may be (the "SUCCESSOR
         COMPANY"), to which a holder of the number of shares of Common Stock
         deliverable upon the exercise (immediately prior to the time of such
         consolidation, share exchange, merger, or sale) of this Warrant would
         have been entitled upon such consolidation, share exchange, merger, or
         sale; and in any such case appropriate adjustments shall be made in the
         application of the provisions set forth herein with respect to the
         rights and interests of the registered Holder of this Warrant, such
         that the provisions set forth herein shall thereafter correspondingly
         be made applicable, as nearly as may reasonably be, in relation to the
         number and kind of securities or the type and amount of property
         thereafter deliverable upon the exercise of this Warrant. The above
         provisions shall similarly apply to successive consolidations, share
         exchanges, mergers, and sales. Any adjustment required by this Section
         4(a) because of a consolidation, share exchange, merger, or sale shall
         be set forth in an undertaking delivered to the registered Holder of
         this Warrant and executed by the Successor Company which provides that
         the Holder of this Warrant shall have the right to exercise this
         Warrant for the kind and number of securities or amount and kind of
         property of the Successor Company or to which the holder of a number of
         shares of Common Stock deliverable upon exercise (immediately prior to
         the time of such consolidation, share exchange, merger, or sale) of
         this Warrant would have been entitled upon such consolidation, share
         exchange, merger, or sale. Such undertaking shall also provide for
         future adjustments to the number of Repricing Shares and the Exercise
         Price in accordance with the provisions set forth in this Section 4.

                   (b) In the event the Company should at any time, or from time
         to time after the Original Issue Date, fix a record date for the
         effectuation of a stock split or subdivision of the outstanding shares
         of Common Stock or the determination of holders of Common Stock
         entitled to receive a dividend or other distribution payable in
         additional shares of Common Stock, or securities or rights convertible
         into, or entitling the holder thereof to receive directly or
         indirectly, additional shares of Common Stock (hereinafter referred to
         as "COMMON STOCK EQUIVALENTS") without payment of any consideration by
         such holder for the additional shares of Common Stock or the Common
         Stock Equivalents (including the additional shares of Common Stock
         issuable upon exercise or exercise thereof), then, as of such record
         date (or the date of such dividend, distribution, split, or subdivision
         if no record date is fixed), the number of Repricing Shares issuable
         upon the exercise hereof shall be proportionately increased and the
         Exercise Price shall be appropriately decreased by the same proportion
         as the increase in the number of outstanding Common Stock Equivalents
         of the Company resulting from the dividend, distribution, split, or
         subdivision. Notwithstanding the preceding sentence, no adjustment
         shall be made to decrease the Exercise Price below $.01 per Share.

                                        4
<PAGE>

                   (c) In the event the Company should at any time or from time
         to time after the Original Issue Date, fix a record date for the
         effectuation of a reverse stock split, or a transaction having a
         similar effect on the number of outstanding shares of Common Stock of
         the Company, then, as of such record date (or the date of such reverse
         stock split or similar transaction if no record date is fixed), the
         number of Repricing Shares issuable upon the exercise hereof shall be
         proportionately decreased and the Exercise Price shall be appropriately
         increased by the same proportion as the decrease of the number of
         outstanding Common Stock Equivalents resulting from the reverse stock
         split or similar transaction.

                   (d) In the event the Company should at any time or from time
         to time after the Original Issue Date, fix a record date for a
         reclassification of its Common Stock, then, as of such record date (or
         the date of the reclassification if no record date is set), this
         Warrant shall thereafter be convertible into such number and kind of
         securities as would have been issuable as the result of such
         reclassification to a holder of a number of shares of Common Stock
         equal to the number of Repricing Shares issuable upon exercise of this
         Warrant immediately prior to such reclassification, and the Exercise
         Price shall be unchanged.

                   (e) The Company will not, by amendment of its Certificate of
         Incorporation or through reorganization, consolidation, merger,
         dissolution, issue, or sale of securities, sale of assets or any other
         voluntary action, void or seek to avoid the observance or performance
         of any of the terms of the Warrant, but will at all times in good faith
         assist in the carrying out of all such terms and in the taking of all
         such actions as may be necessary or appropriate in order to protect the
         rights of the Holder against dilution or other impairment. Without
         limiting the generality of the foregoing, the Company (x) will not
         create a par value of any share of stock receivable upon the exercise
         of the Warrant above the amount payable therefor upon such exercise,
         and (y) will take all such action as may be necessary or appropriate in
         order that the Company may validly and legally issue fully paid and
         non-assessable shares upon the exercise of the Warrant.

                   (f) When any adjustment is required to be made in the number
         or kind of shares purchasable upon exercise of the Warrant, or in the
         Exercise Price, the Company shall promptly notify the Holder of such
         event and of the number of shares of Common Stock or other securities
         or property thereafter purchasable upon exercise of the Warrants and of
         the Exercise Price, together with the computation resulting in such
         adjustment.

                   (g) The Company covenants and agrees that all Repricing
         Shares which may be issued will, upon issuance, be validly issued,
         fully paid, and non-assessable. The Company further covenants and
         agrees that the Company will at all times have authorized and reserved,
         free from preemptive rights, a sufficient number of shares of its
         Common Stock to provide for the exercise of the Warrant in full.

         SECTION 5. NO STOCKHOLDER RIGHTS. This Warrant shall not entitle the
Holder hereof to any voting rights or other rights as a stockholder of the
Company.

         SECTION 6. TRANSFER OF SECURITIES.

                   (a) This Warrant and the Repricing Shares and any shares of
         capital stock received in respect thereof, whether by reason of a stock
         split or share reclassification thereof, a stock dividend thereon, or
         otherwise, shall not be transferable except upon compliance with the
         provisions of the Securities Act of 1933, as amended (the "SECURITIES
         ACT"), and applicable state securities laws with respect to the
         transfer of such securities. The Holder of this Warrant, by acceptance
         of this Warrant, agrees to be bound by the provisions of Section 4
         hereof and to indemnify and hold harmless the Company against any loss
         or liability arising from the disposition of this Warrant or the
         Repricing Shares issuable upon exercise hereof or any interest in
         either thereof in violation of the provisions of this Warrant.

                   (b) Each certificate for the Repricing Shares and any shares
         of capital stock received in respect thereof, whether by reason of a
         stock split or share reclassification thereof, a stock dividend thereon
         or otherwise, and each certificate for any such securities issued to
         subsequent transferees of any such certificate shall (unless otherwise
         permitted by the provisions hereof) be stamped or otherwise imprinted
         with a legend in substantially the following form:

         Legend for Repricing Shares or other shares of capital stock:

         THE SHARES OF COMMON STOCK ISSUABLE UPON EXERCISE  HEREOF HAVE NOT BEEN
         REGISTERED  UNDER  THE  SECURITIES  ACT OF  1933,  AS  AMENDED,  OR ANY
         APPLICABLE  STATE  SECURITIES  LAW AND NEITHER MAY BE SOLD OR OTHERWISE
         TRANSFERRED  UNTIL (I) A REGISTRATION  STATEMENT  UNDER SUCH SECURITIES
         ACT AND  SUCH  APPLICABLE  STATE  SECURITIES  LAWS  SHALL  HAVE  BECOME
         EFFECTIVE WITH REGARD THERETO,  OR (II) THE COMPANY SHALL HAVE RECEIVED
         A WRITTEN  OPINION OF COUNSEL  ACCEPTABLE  TO THE COMPANY TO THE EFFECT
         THAT  REGISTRATION  UNDER SUCH SECURITIES ACT AND SUCH APPLICABLE STATE
         SECURITIES  LAWS IS NOT  REQUIRED  IN  CONNECTION  WITH  SUCH  PROPOSED
         TRANSFER.

         SECTION 7. PIGGYBACK REGISTRATION RIGHTS.

                   (a) If the Company shall at any time following the Vesting
         Date commence file a registration statement under the Securities Act
         with respect to a public offering of its securities (other than on
         Forms S-8, S-14 or S-15 or other similar form inappropriate to
         registration of the Repricing Shares), and pursuant to the then
         applicable rules and regulations under the Securities Act , a secondary
         offering of the Repricing Shares by the Holder may be combined with
         such public offering in a single registration. The Company shall, in
         every such instance give reasonable written notice thereof to Holder
         thirty (30) or more days prior to the filing of such registration
         statement, and shall upon the written request of Holder made within
         fifteen (15) days of the mailing of said written notice by the Company,
         include in such registration statement such number of Repricing Shares
         as Holder may request. Any such registration statement shall remain
         effective for a period of not less than one hundred, twenty (120) days,
         or the Exercise Period, following its effective date. The inclusion of
         such Repricing Shares in any registration statement shall be without
         any expense to Holder, other than fees and expenses of counsel to
         Holder and any underwriting discounts and commissions. Neither the
         delivery of such notice by the Company nor such request by Holder shall
         in any way obligate the Company to file such registration statement,
         and notwithstanding the filing of such registration statement, the
         Company may, at any time prior to the effective date thereof, determine
         not to offer the securities to which such registration statement
         relates, without liability to the Holder. In the even the Company fails
         to receive written notice from the Holder within fifteen (15) days of
         the mailing of said written notice by the Company, then the Company
         shall treat such failure as having the same force and effect as if
         Holder had advised the Company that Holder does not intend to include
         any Repricing Shares in such registration statement.

                                        6
<PAGE>

                   (b) Notwithstanding the provisions of Subsection (a) above,
         if the offering subject to any registration statement referred to in
         Subsection (a) is made by the Company and is underwritten, and if the
         underwriter makes a written determination prior to the effectiveness of
         such registration statement and so requests and such request is based
         upon the opinion of the underwriter that the sale of the Repricing
         Shares to be registered on such registration statement by Holder
         pursuant to Subsection (a) will materially and adversely interfere with
         such planned offering, then: (i) Holder shall agree not to sell any
         Repricing Shares, whether pursuant to such registration statement or
         otherwise, for a period not to exceed ninety (90) days following the
         effective date of such registration statement, and the Company shall,
         at the expiration of the ninety (90) day period, at its expense,
         maintain the currency of the registration statement and take such other
         steps as may be required to permit Holder to sell the Repricing Shares
         pursuant to such registration statement for an additional period of
         ninety (90) days following expiration of such ninety (90) day period;
         provided, however, that the Company shall have no duty to file any
         amendment to any such registration statement at any time that the
         Company reasonably believes that disclosure of the information required
         to be included in such amendment would be premature or contrary to the
         best interests of the Company and its security holders; and (ii) Holder
         shall agree that the Repricing Shares shall be sold through such
         underwriter in the same manner as the other securities that are the
         subject of the registration, and shall pay to such underwriter a
         commission in respect of such Repricing Shares at the same rate as the
         commission to be paid to such underwriter in respect of the other
         securities that are the subject of such registration.

                   If securities are proposed to be offered for sale pursuant to
         such registration statement by other selling security holders of the
         Company, and the total number of securities to be offered by Holder and
         such other selling security holders is required to be reduced pursuant
         to a request from the underwriter (which request shall be made only for
         the reasons and in the manner set forth above in this Subsection (b)),
         then the number of Repricing Shares to be offered by Holder pursuant to
         such registration statement shall equal the number that bears the same
         ratio to the maximum number of securities that the underwriter believes
         may be included for all the selling security holders (including the
         Holder) as the original number of Repricing Shares proposed to be sold
         by Holder bears to the total original number of securities proposed to
         be offered by Holder and the other selling security holders. In no
         event shall there be a reduction in the number of shares of any
         securities offered by the Company pursuant to the registration
         statement referred to in Subsection (a) above.

                   (c) The Company shall use its best efforts to cause any
         registration statement covering all or any portion of the Repricing
         Shares to become effective as promptly as possible and, if any stop
         order shall be issued in connection therewith, to use its best efforts
         to obtain removal of such order. The Company shall furnish the selling
         Holder with copies of preliminary prospectuses (together with any
         supplements thereto) and other documents necessary or incidental to the
         offering being made by Holder in such quantities as Holder may
         reasonably request. Holder agrees to cooperate in all respects with the
         Company in effectuating the foregoing. The obligations of the Company
         to Holder hereunder are expressly conditioned on the timely furnishing
         in writing by Holder to the Company of such information concerning
         Holder and the terms of Holder's proposed offering as the Company may
         reasonably request.

<PAGE>

                   (d) In connection with any registration of all or any portion
         of the Repricing Shares, the Company shall, without any expense to
         Holder (other than fees and expenses of counsel to Holder and any
         underwriting discounts or commissions), prepare and file such documents
         as may be necessary to register or qualify the Repricing Shares under
         the securities or blue sky laws of such states as Holder shall
         reasonably request, and use its best efforts to do any and all other
         acts and things, consistent with its existing business practices, that
         may reasonably be necessary or advisable to enable the Holder to
         consummate a public sale in such states of such Repricing Shares;
         provided, however, that in connection with any registration statement
         files pursuant to Subsection (a) above, the Company shall be required
         to make the Repricing Shares eligible for public offering and sale only
         in such state (including the District of Columbia) as any other
         securities of the Company included in such registration statement are
         eligible for public offering and sale. In no event shall the Company be
         obligated to qualify to do business in any state where it is not so
         qualified at the time of filing such documents or to take any action
         which would subject it to unlimited service of process in any state
         where it is not so subject at such time. The Company shall keep any
         such filing current for the time period it is obligated to keep any
         registration statement current pursuant to Subsections (a) or (b).

                   (e) The provisions of this Section 7 shall apply to the
         extent provided herein if the Company chooses to file an offering
         statement under Regulation A promulgated under the Act.

                   (f) The Company agrees that until the Repricing Shares have
         been sold under a registration statement or pursuant to Rule 144 under
         the Act, it shall keep current in filing all materials required to be
         filed with the U.S. Securities and Exchange Commission in order to
         permit holders of the Repricing Shares, if they otherwise comply with
         the requirements of Rule 144, to sell Repricing Shares under such Rule.

         SECTION 8. MISCELLANEOUS.

                   (a) The terms of this Warrant shall be binding upon and shall
         inure to the benefit of any successors or assigns of the Company and of
         the holder or holders hereof and of the Common Stock issued or issuable
         upon the exercise hereof.

                   (b) Except as otherwise provided herein, this Warrant and all
         rights hereunder are transferable by the registered holder hereof in
         person or by duly authorized attorney on the books of the Company upon
         surrender of this Warrant, properly endorsed, to the Company. The
         Company may deem and treat the registered holder of this Warrant at any
         time as the absolute owner hereof for all purposes and shall not be
         affected by any notice to the contrary.

                   (c) Notwithstanding any provision herein to the contrary,
         Holder hereof may not exercise, sell, transfer, or otherwise assign
         this Warrant unless the Company is provided with an opinion of counsel
         satisfactory in form and substance to the Company, to the effect that
         such exercise, sale, transfer, or assignment would not violate the
         Securities Act or applicable state securities laws.

                   (d) This Warrant may be divided into separate Warrants
         covering one share of Common Stock or any whole multiple thereof, for
         the total number of shares of Common Stock then subject to this Warrant
         at any time, or from time to time, upon the request of the registered
         holder of this Warrant and the surrender of the same to the Company for
         such purpose. Such subdivided Warrants shall be issued promptly by the
         Company following any such request and shall be of the same form and
         tenor as this Warrant, except for any requested change in the name of
         the registered holder stated herein.

             THE TRANSFER OF THIS WARRANT IS SUBJECT TO RESTRICTIONS
                CONTAINED HEREIN. THIS WARRANT HAS BEEN ISSUED IN
               RELIANCE UPON THE REPRESENTATION OF THE HOLDER THAT
                IT HAS BEEN ACQUIRED FOR INVESTMENT PURPOSES AND
                   NOT WITH A VIEW TOWARDS THE RESALE OR OTHER
                 DISTRIBUTION THEREOF. NEITHER THIS WARRANT NOR
                  THE SHARES ISSUABLE UPON THE EXERCISE OF THIS

                          Common Stock Purchase Warrant

                                August    , 1998
                                       ---

THIS CERTIFIES that, pursuant to the signed and executed License Agreement dated
August 5, 1998 by and between ___________, (the "Holder") and SPACEDEV, INC., a
Colorado corporation (hereinafter called the "Corporation"), the Holder shall
receive Warrants entitling the Holder to purchase from the Corporation its
Common Stock under the following terms and conditions:

                  NUMBER OF SHARES: Holder shall be entitled to subscribe and
                  purchase the following shares of SpaceDev Common stock:

                  1.   Upon the execution of License Agreement, the Holder
                       shall be entitled to purchase 25,000 shares.

                  2.   For the next three anniversaries of the License
                       Agreement, the Holder shall entitled to purchase the
                       greater of (i) 25,000 shares or (ii) one share for
                       each One Hundred Twenty-five dollars ($125) in
                       revenue earned from the sale of the Technology as
                       referenced in the License Agreement.

                  3.   For the fourth through the tenth anniversary of the
                       License Agreement, the Holder is entitled to purchase
                       25,000 shares per year.

                  STRIKE PRICE: Holder shall be entitled to exercise the
                  warrants at the strike price equal to fifty percent (50%) of
                  the average SpaceDev Common Stock closing price for the five
                  business days prior to the date the shares are to be
                  exercised.

                                       1
<PAGE>

                  MAXIMUM LIMITATION: Under no event shall the Warrants entitle
                  the Holder, in cumulative, to purchase more than (i) three
                  million (3,000,000) shares; or (ii) six million dollars
                  ($6,000,000) in Recognized Value. Recognized Value shall be
                  defined as the cumulative difference between the then current
                  full market value of the shares for which warrants have been
                  issued or exercised, as traded on the exchange on the date
                  that the warrants are first exercisable; and the price
                  actually paid for the stock (or if the warrants have not been
                  exercised, the price Summit would have paid for the stock on
                  the first day the warrants could be exercised), multiplied by
                  the number of shares for which warrants have been issued or
                  exercised.

                                    SECTION 1
                               EXERCISE OF WARRANT
                               -------------------

         The rights represented by this Warrant may be exercised by the Holder,
in whole at any time or from time to time in part, but not as to a fractional
share of Common Stock, by the completion of the purchase form attached hereto
and by the surrender of this Warrant (properly endorsed) at the office of the
Corporation as it may designate by notice in writing to the Holder hereof at the
address of the Holder appearing on the books of the Corporation, and by payment
to the Corporation of the Warrant Price in cash or by certified or official bank
check, for each share being purchased.

         In the event of any exercise of the rights represented by this Warrant,
a certificate or certificates for the shares of Common Stock so purchased,
registered in the name of the Holder, or its nominee or other party designated
in the purchase form by the Holder hereof, shall be delivered to the Holder
within thirty (30) business days after the date in which the rights represented
by this Warrant shall have been so exercised; and, unless this Warrant has
expired or has been exercised in full, a new Warrant representing the number of
shares (except a remaining fractional share), if any, with respect to which this
Warrant shall not then have been exercised shall also be issued to the Holder
within such time.

         The person in whose name any certificate for shares of Common Stock is
issued upon exercise of this Warrant shall for all purposes be deemed to have
become the Holder of record of such shares on the date on which this Warrant was
surrendered and payment of the Warrant Price, except that, if the date of such
surrender and payment is a date on which the stock transfer books of the
Corporation are closed, such person shall be deemed to have become the Holder of
such shares at the close of business on the next succeeding date on which the
stock transfer books are open. No fractional shares shall be issued upon
exercise of this Warrant and no payment or adjustment shall be made upon any
exercise on account of any cash dividends on the Common Stock issued upon such
exercise. If any fractional interest in a share of Common Stock would, except
for the provision of this Section 1, be delivered upon such exercise, the
Corporation, in lieu of delivery of a fractional share thereof, shall pay to the

                                       2
<PAGE>

Holder an amount in cash equal to the current market price of such fractional
share as determined in good faith by the Board of Directors of the Corporation
(the "Board").

                                    SECTION 2
                  STOCK SPLITS, CONSOLIDATION, MERGER AND SALE
                  --------------------------------------------

         In the event the outstanding shares of Common Stock shall be split,
combined or consolidated, by dividend, reclassification or otherwise, into a
greater or lesser number of shares of Common Stock, the Warrant Price in effect
immediately prior to such combination or consolidation and the number of shares
purchasable under this Warrant shall, concurrently with the effectiveness of
such combination or consolidation, be proportionately adjusted.

         If there shall be effected any consolidation or merger of the
Corporation with another corporation, or a sale of all or substantially all of
the Corporation's assets to another corporation, and if the holders of Common
Stock shall be entitled pursuant to the terms of any such transaction to receive
stock, securities or assets with respect to or in exchange for Common Stock,
then, as a condition of such consolidation, merger or sale, lawful and adequate
provisions shall be made whereby the Holder of this Warrant shall thereafter
have the right to receive, upon the basis and upon the terms and conditions
specified herein and in lieu of the shares of Common Stock immediately
theretofore receivable upon the exercise of such Warrant, such shares of stock,
securities or assets as may be issuable or payable with respect to or in
exchange for a number of outstanding shares of such Common Stock equal to the
number of shares of such Common Stock immediately theretofore so receivable had
such consolidation, merger or sale not taken place, and in any such case
appropriate provisions shall be made with respect to the rights and interests of
the Holder to the end that the provisions hereof shall thereafter be applicable,
as nearly as may be, in relation to any shares of stock, securities or assets
thereafter deliverable upon the exercise of this Warrant.

         (a) STOCK TO BE RESERVED. The Corporation will at all times reserve and
         keep available out of its authorized Common Stock, solely for the
         purpose of issue upon the exercise of this Warrant as herein provided,
         such number of shares of Common Stock as shall then be issuable upon
         the exercise of this Warrant. The Corporation shall from time to time
         in accordance with applicable law increase the authorized amount of its
         Common Stock if at any time the number of shares of Common Stock
         remaining unissued and available for issuance shall not be sufficient
         to permit exercise of this Warrant. The Corporation covenants that all
         shares of Common Stock which shall be so issued shall be duly and
         validly issued and fully paid and nonassessable and free from all
         taxes, liens and charges with respect to the issue thereof, and,
         without limiting the generality of the foregoing, the Corporation will
         take all such action as may be necessary to assure that all such shares
         of Common Stock may be so issued without violation of any applicable

                                       3
<PAGE>

         law or regulation, or of any requirements of any national securities
         exchange upon which the Common Stock of the Corporation may be listed.

         (b) ISSUE TAX. The issuance of certificates for shares of Common Stock
         upon exercise of this Warrant shall be made without deduction to the
         Holders of this Warrant for any issuance tax in respect thereof
         provided that the Corporation shall not be required to pay any tax
         which may be payable in respect of any transfer involved in the
         issuance and delivery of any certificate in a name other than that of
         Holder of this Warrant.

         (c) CLOSING OF BOOKS. The Corporation will at no time close its
         transfer books against the transfer of the shares of Common Stock
         issued or issuable upon the exercise of this Warrant in any manner
         which interferes with the timely exercise of this Warrant.

                                    SECTION 3
                             NOTICES OF RECORD DATES
                             -----------------------

In the event of:

         (1)      any taking by the Corporation of a record of the Holders of
                  any class of securities for the purpose of determining the
                  Holders thereof who are entitled to receive any dividend or
                  other distribution (other than cash dividends out of earned
                  surplus), or any right to subscribe for, purchase or otherwise
                  acquire any shares of stock of any class or any other
                  securities or property, or to receive any other right;

         (2)      any capital reorganization of the Corporation, any
                  reclassification, or recapitalization of the capital stock of
                  the Corporation, or any transfer of all or substantially all
                  the assets of the Corporation to, or consolidation or merger
                  of the Corporation with or into any other corporation; or

         (3)      any voluntary or involuntary dissolution, liquidation or
                  winding-up of the Corporation;

then and in each such event the Corporation will give notice to the Holder of
this Warrant specifying (i) the date on which any such record is to be taken for
the purpose of such dividend, distribution or right and stating the amount and
character of such dividend, distribution or right, and (ii) the date on which
any such reorganization, reclassification, recapitalization, transfer,
consolidation, merger, dissolution, liquidation or winding-up is to take place,
and the time, if any is to be fixed, as of which the Holders of record of Common
Stock will be entitled to exchange their shares of Common Stock for securities
or other property deliverable upon such reorganization, reclassification,
recapitalization, transfer, consolidation, merger, dissolution, liquidation or
winding-up. Such notice shall be given at least 10 days and not more than 90

                                       4
<PAGE>

days prior to the date therein specified, and such notice shall state that the
action in question or the record date is subject to the effectiveness of a
registration statement under the Securities Act of 1933 or to a favorable vote
of shareholders, if either is required.

                                    SECTION 4
                      NO SHAREHOLDER RIGHTS OR LIABILITIES
                      ------------------------------------

         This Warrant shall not entitle the Holder hereof to any voting rights
or other rights as a shareholder of the Corporation. No provision hereof, in the
absence of affirmative action by the Holder hereof to purchase shares of Common
Stock, and no mere enumeration hereon of the rights or privileges of the Holder
hereof, shall give rise to any liability of such Holder for the Warrant Price or
as a shareholder of the Corporation, whether such liability is asserted by the
Corporation or by creditors of the Corporation.

notice to the Corporation of such Holder's intention to effect such transfer.

and/or Warrant Shares may be effected without registration under the Securities
Act, or (ii) a "no action" letter from the U.S. Securities and Exchange
Commission (the "Commission") to the effect that the transfer of such securities
without registration will not result in a recommendation by the staff of the
Commission that enforcement action be taken with respect thereto, whereupon the

accordance with the terms of the notice delivered by the Holder to the
Corporation. Each new certificate evidencing the Warrant and/or Warrant Shares
so transferred shall bear the appropriate restrictive legends set forth in
Section 5 above, except that such certificate shall not bear such restrictive

required in order to establish or assist in compliance with any provisions of
the Securities Act or any applicable state securities laws.

      such breach or breaches for which the SIL Warrantors are liable exceeds
      $15,000, in which event a claim in respect of the excess over $15,000 may
      be made;

(c)   the maximum liability of each SIL Warrantor in respect of the aggregate of
      all the claims made by SpaceDev in respect of any breach of this Agreement
      shall not exceed five hundred thousand dollars ($500,000).

2.26  SpaceDev may not bring any claim for breach of the provisions of this
      Agreement unless written notice of the claim shall have been given to the
      SIL Warrantors accompanied by reasonable particulars of the claim,
      including the amount of the claim:

(a)   in the case of any claim under the Warranties under Article 2, within 12
      months of the date of this Agreement; and

(b)   in the case of any other claim, within 3 months of the date of this
      Agreement, provided that the liability of the SIL Warrantors in respect of
      any Warranty Claim shall absolutely terminate if proceedings in respect of
      it have not been commenced within 2 months of service of notice of that
      claim.

                                       16
<PAGE>

2.27  The SIL Warrantors shall not be liable and no claim or claims shall be
      made against them in respect of any Warranty Claim:

(a)   if the fact, omission, circumstance or occurrence giving rise to or
      forming the basis of the claim has been fairly disclosed to SpaceDev in
      the Disclosure Letter;

(b)   to the extent that provision or allowance for the matter or liability has
      been made in the Financial Statements or is otherwise taken account of, or
      reflected in, the Financial Statements;

(c)   to the extent that the claim would not have arisen but for a change in
      legislation made after the date of this Agreement (whether relating to
      taxation, rates of taxation or otherwise) or the withdrawal of any
      extra-statutory concession previously made by the IRS or other taxing
      authority (whether or not the change purports to be effective
      retrospectively in whole or in part);

(d)   if the matter giving rise to the claim is provided for under the terms of
      this Agreement or carried out in the implementation of it;

(e)   to the extent the liability of the SIL Warrantors in respect of the claim
      is affected by any voluntary act (other than in the ordinary course of
      business of SIL) of SpaceDev or of SIL carried out on, or after the date
      of this Agreement;

(f)   if the claim arises from any act, matter or thing done or omitted to be
      done by SpaceDev or SIL at the request or with the approval of SpaceDev;

(g)   if the claim arises from SpaceDev or SIL disclaiming any part of the
      benefit of capital or other allowances against taxation claimed or
      proposed to be claimed on or before the date of this Agreement of which
      particulars have been given to SpaceDev; or

(h)   if the claim arises from any change in accounting policy or practice of
      SpaceDev or SIL introduced or having effect after Closing.

2.28  If SpaceDev becomes aware of a matter which could give rise to a claim
      under the other provisions of this Agreement, the SIL Warrantors shall not
      be liable in respect of it unless written notice of the relevant facts is
      given by SpaceDev to the SIL Warrantors as soon as reasonably practicable
      and in any event within 30 days of SpaceDev becoming aware of those facts.

2.29  Without prejudice to SpaceDev's duty to mitigate any loss in respect of
      any breach of the Warranties, any damages for such breach shall be
      assessed on the basis of the diminution in value of the SIL Shares (which
      value shall not be taken to be greater than the Consideration) directly
      attributable to the breach in question (after taking into account all
      compensating factors) and not on the basis of the loss of or cost to SIL
      in respect of the matter giving rise to the claim.

                                       17
<PAGE>

2.30  Without prejudice to any duty it may have at common law or otherwise,
      SpaceDev shall use all reasonable endeavors to mitigate any loss or damage
      which it may suffer in consequence of any breach by the SIL Warrantors of
      the Warranties or other provisions of this Agreement.

2.31  If in respect of any matter which could give rise to a breach of the
      Warranties SpaceDev or SIL is entitled to claim under any policy of
      insurance (or would have been so entitled had it maintained in force the
      insurance cover current at Closing) no such matter shall be the subject of
      a claim unless and until the SpaceDev or SIL shall have made a claim
      against its insurers and the amount of such claim (or of any claim which
      could have been made had such policies or their equivalents been
      maintained in effect after Closing) shall then reduce or extinguish any
      such claim.

2.32  If any claim for breach of any of the Warranties is based upon a liability
      of SIL which is contingent only, the SIL Warrantors shall not be liable to
      make any payment to SpaceDev or to SIL unless and until such contingent
      liability becomes an actual liability and is discharged.

2.33  If any of the SIL Warrantors makes any payment by way of damages in
      respect of a Warranty Claim (the "DAMAGES PAYMENT") and within 12 months
      of the making of the Damages Payment SIL or SpaceDev receives any benefit
      otherwise than from that SIL Warrantor which it would not have received
      but for the circumstance giving rise to the claim in respect of which the
      Damages Payment was made, SpaceDev shall, once it or SIL has received such
      benefit, forthwith repay to that SIL Warrantor the Damages Payment in so
      far as it does not exceed the value of the benefit recovered from the
      third party.

2.34  Any liability of the SIL Warrantors will take account of any corresponding
      savings or benefits accruing to SpaceDev or SIL as a result of the
      circumstances giving rise to the Warranty Claim. If any provision in the
      Financial Statements for taxation proves to be an over-provision, the
      amount of the over-provision will be set off against any liability of the
      Warrantors under this Agreement.

2.35  Subject to the other provisions of this Article 2, it is hereby agreed
      that each individual SIL Warrantor shall have no liability in respect of
      any claim made by SpaceDev for breach of any of the provisions of this
      Agreement if such claim or claims shall have arisen by reason of fraud,
      dishonesty or deliberate non-disclosure on the part of any other SIL
      Warrantor.

2.36  Notwithstanding Article 2.35 none of the SIL Warrantors shall, as between
      each other be liable to make a contribution in respect of any payment made
      or agreed to be made by any other SIL Warrantors in respect of any claim
      under, or in respect of, any breach of this Agreement unless such SIL
      Warrantor has been adequately consulted in the course of negotiations
      following the notification of any such claim and has been joined as a
      party to any proceedings in which that claim has been made.

                                       18
<PAGE>

2.37  Any amount paid by the SIL Warrantors in respect of any claim under this
      Agreement shall be deemed to be a reduction in the purchase consideration
      for the SIL Shares.

2.38  The liability of each individual SIL Warrantor in respect of any claim
      made by SpaceDev for breach of the SIL Warranties or any other provisions
      of this Agreement shall not exceed the proportion set out below against
      the name of that SIL Warrantor of the amount of any such claim or claims.

      $2,500,000 maximum liability to SpaceDev and to the extent of $500,000
      maximum liability to Guarantor) to the SIL Shareholders that except as
      fairly disclosed in the letter to the SIL Shareholders dated the same date

      (a)  the SpaceDev Warranties are the only representations, warranties or
           other assurances of any kind given by or on behalf of the SpaceDev
           Warrantors and on which the SIL Shareholders may rely in entering
           into this Agreement;

      (b)  no other statement, promise or forecast made by or on behalf of the
           SpaceDev Warrantors may form the basis of, or be pleaded in
           connection with, any claim by the SIL Shareholders under or in
           connection with this Agreement; and

      (c)  at the time of entering into this Agreement the SIL Shareholders are
           not aware of any matter or thing which is inconsistent with the
           SpaceDev Warranties or constitutes a breach of any of them.

3.7    Financial Statements; Changes; Contingencies.
       ---------------------------------------------

                                       20
<PAGE>

      (a)  FINANCIAL STATEMENTS. SpaceDev has delivered to the SIL Shareholders
           the unaudited December 31, 1997 balance sheet for SpaceDev and the
           related statements of income for the 12 months then ended. All such
           interim financial statements have been prepared in accordance with
           GAAP consistently applied during the periods covered (except as
           disclosed therein), the statements of income present fairly the
           results of operations of SpaceDev for the respective periods covered,
           and the balance sheets present fairly the financial condition of
           SpaceDev as of their respective dates, except that such financial
           statements may omit footnote disclosures required by GAAP to the
           extent the content thereof would not materially differ in nature or
           amount from those disclosures reported in the most recent audited
           period, and year-end adjustments to the extent not material.
           Notwithstanding the foregoing, all such financial statements reflect
           all material adjustments (which consist only of normal recurring
           adjustments not material in amount) necessary for a fair
           presentation.

      (b)  NO MATERIAL ADVERSE CHANGES. Since the Statement Date, whether in the
           ordinary course of business, there has not been, occurred or arisen:

           1.   any change in or event affecting SpaceDev, its business or the
                Common Stock of SpaceDev that has had or may reasonably be
                expected to have a Material Adverse Effect.

           2.   any agreement (other than a Material Contract listed in the
                Disclosure Letter), condition, action or omission which would be
                proscribed by (or require consent under) section 4.3 had it
                existed, occurred or arisen after the date of this Agreement,

           3.   any strike or other labor dispute, or

           4.   any casualty, loss, damage or destruction whether or not covered
                by insurance or any material property of SpaceDev.

      (c)  NO OTHER LIABILITIES OR CONTINGENCIES. SpaceDev does not have any
           material liabilities of any nature, whether accrued, absolute,
           contingent or otherwise, and whether due or to become due, probable
           of assertion or not, that, in accordance with GAAP applied on a
           consistent basis, should have been but were not reflected or
           disclosed in the financial statements (including the notes thereto)
           referred to in subsection 3.7(a) and (b) above, except liabilities
           which were incurred after Statement Date, in the ordinary course of
           business which do not exceed $10,000 exclusive of current payroll and
           payroll taxes for the payroll period ending immediately prior to
           Closing.

3.8    Authorization; No Conflicts.
       ----------------------------

The execution, delivery and performance of this Agreement and or related
agreements by SpaceDev and the Guarantor have been duly and validly authorized
by the Board of Directors of SpaceDev and by all other necessary corporate
action on the part of SpaceDev and by the Guarantor. SpaceDev and the Guarantor
have the full capacity, right, power and authority to enter into this Agreement
and any related agreements to which they are parties. The execution, delivery
and performance of this Agreement by SpaceDev and the Guarantor and the
execution, delivery and performance of any related agreements or contemplated
transactions by SpaceDev and the Guarantor will not violate, or constitute a
breach or default (whether upon lapse of time and/or the occurrence of any act
or event or otherwise) under, the Articles of Incorporation or by-laws of
SpaceDev or any Material Contract, result in the imposition of any Encumbrance
against any asset or properties of SpaceDev, or violate any Law. The
consummation of the transactions contemplated by this Agreement does not, to the
knowledge of SpaceDev and the Guarantor require any filings under the
Hart-Scott-Rodino Act.

3.14   Tax and Other Reports and Regulatory Matters
       --------------------------------------------

The United States Securities and Exchange Commission (SEC) has issued an Order
Instituting Proceedings for a Cease and Desist order to be issued against
SpaceDev alleging the Company has made statement contained in press releases and
on the Company's web site including information published by the Company
relating to its projected revenues and earnings, the nature and status of the
Company's relationship with the National Aeronautics and Space Administration,
and the nature of the Company's relationship with an underwriter which violate
the securities laws. The SEC has requested an order issued against the Company
to cease and desist making these and similar statements. The Company disagrees
with the SEC's position and believes their position is without merit. A hearing
will be held before an Administrative Law Judge to determine the merits of the
allegations made by the SEC. The Company has issued a news release relating to
these matters which, along with the Order Instituting Proceedings issued by the
SEC are contained in the Disclosure Letter. The SIL Shareholders agree that they
have not relied on any information published by SpaceDev or any information
which is contained in the SEC Order Instituting Proceedings. The SIL
Shareholders have completed their own independent investigation of SpaceDev
prior to entering into this Agreement and have received and reviewed all
information they feel necessary regarding the SEC matter during their
investigation.

3.15   The liability of the SpaceDev Warrantors under this Agreement shall be
       limited as follows:
       -------------------

      (a)  there shall be disregarded for all purposes any breach of this
           Agreement unless the amount of damages to which the SIL Shareholders
           would otherwise be entitled is an amount in excess of $15,000;

      (b)  the SIL Shareholders shall not be entitled to recover any damages in
           respect of any breach or breaches of the SpaceDev Warranties unless
           the aggregate loss or damage amount in respect of all such breach or
           breaches for which the SpaceDev Warrantors are liable exceeds
           $15,000, in which event a claim in respect of the excess over $15,000
           may be made;

      (c)  the maximum liability of SpaceDev in respect of the aggregate of all
           the claims made by the SIL Shareholders in respect of any breach of
           this Agreement shall not exceed two million five hundred thousand
           dollars ($2,500,000). The maximum liability of the Guarantor in
           respect of the aggregate of all the claims made by the SIL
           Shareholders in respect of any breach of this Agreement shall not
           exceed five hundred thousand dollars ($500,000).

3.16  SpaceDev may not bring any claim for breach of the provisions of this
      Agreement unless written notice of the claim shall have been given to the
      SpaceDev Warrantors accompanied by reasonable particulars of the claim,
      including the amount of the claim:

      (a)  in the case of any claim under the SpaceDev Warranties, within 12
           months of the date of this Agreement; and

      (b)  in the case of any other claim, within 3 months of the date of this
           Agreement, provided that the liability of the SpaceDev Warrantors in
           respect of any SpaceDev Warranty Claim shall absolutely terminate if
           proceeding in respect of it have not been commenced with 2 months of
           service of notice of that claim.

                                       23
<PAGE>

3.17  The SpaceDev Warrantors shall not be liable and no claim or claims shall
      be made against them in respect of any SpaceDev Warranty Claim:

      (a)  if the fact, omission, circumstance or occurrence giving rise to or
           forming the basis of the claim has been fairly disclosed to the SIL
           Shareholders in the SpaceDev Disclosure Letter;

      (b)  to the extent that provision or allowance for the matter or liability
           has been made in the SpaceDev Financial Statements or is otherwise
           taken account of, or reflected in, the SpaceDev Financial Statements;

      (c)  to the extent that the claim would not have arisen but for a change
           in legislation made after the date of this Agreement (whether
           relating to taxation, rates of taxation or otherwise) or the
           withdrawal of any extra-statutory concession previously made by the
           IRS or other taxing authority (whether or not the change purports to
           be effective retrospectively in whole or in part);

      (d)  if the matter giving rise to the claim is provided for under the
           terms of this Agreement or carried out in the implementation of it;

      (e)  to the extent the liability of the SpaceDev Warrantors in respect of
           the claim is affected by any voluntary act (other than in the
           ordinary course of business of SpaceDev) of SpaceDev or of SIL
           carried out on, or after the date of this Agreement;

      (f)  if the claim arises from any act, matter or thing done or omitted to
           be done by SpaceDev or SIL at the request or with the approval of
           SIL;

      (g)  if the claim arises from SpaceDev or SIL disclaiming any part of the
           benefit of capital or other allowances against taxation claimed or
           proposed to be claimed on or before the date of this Agreement of
           which particulars have been given to SIL; or

      (h)  if the claim arises from any change in accounting policy or practice
           of SpaceDev or SIL introduced or having effect after Closing.

3.18  If the SIL Shareholders become aware of a matter which could give rise to
      a claim under the other provisions of this Agreement, the SpaceDev
      Warrantors shall not be liable in respect of it unless written notice of
      the relevant facts is given by the SIL Shareholders to the SpaceDev
      Warrantors as soon as reasonably practicable and in any event within 30
      days of the SIL Shareholders becoming aware of those facts.

                                       24
<PAGE>

3.19  Without prejudice to the SIL Shareholders' duty to mitigate any loss in
      respect of any breach of the SpaceDev Warranties, any damages for such
      breach shall be assessed on the basis of the diminution in value of the
      SpaceDev Shares (which value shall not be taken to be greater than the
      Consideration) directly attributable to the breach in question (after
      taking into account all compensating factors) and not on the basis of the
      loss of or cost to SpaceDev in respect of the matter giving rise to the
      claim.

3.20  Without prejudice to any duty they may have at common law or otherwise,
      the SIL Shareholders shall use all reasonable endeavors to mitigate any
      loss or damage which they may suffer in consequence of any breach by the
      SpaceDev Warrantors of the SpaceDev Warranties or other provisions of this
      Agreement.

3.21  If in respect of any matter which could give rise to a breach of the
      SpaceDev Warranties the SIL Shareholders, SpaceDev or SIL is entitled to
      claim under any policy of insurance (or would have been so entitled had it
      maintained in force the insurance cover current at Closing) no such matter
      shall be the subject of a claim unless and until the SpaceDev or SIL shall
      have made a claim against its insurers and the amount of such claim (or of
      any claim which could have been made had such policies or their
      equivalents been maintained in effect after Closing) shall then reduce or
      extinguish any such claim.

3.22  If any claim for breach of any of the SpaceDev Warranties is based upon a
      liability of SpaceDev which is contingent only, the SpaceDev Warrantors
      shall not be liable to make any payment to the SIL Shareholders unless and
      until such contingent liability becomes an actual liability and is
      discharged.

3.23  If any of the SpaceDev Warrantors makes any payment by way of damages in
      respect of a SpaceDev Warranty Claim (the "DAMAGES PAYMENT") and within 12
      months of the making of the Damages Payment SIL or SpaceDev receives any
      benefit otherwise than from that SpaceDev Warrantor which it would not
      have received but for the circumstance giving rise to the claim in respect
      of which the Damages Payment was made, the SIL Shareholders shall, once
      they or SIL have received such benefit, forthwith repay to that SpaceDev
      Warrantor the Damages Payment in so far as it does not exceed the value of
      the benefit recovered from the third party.

3.24  Any liability of the SpaceDev Warrantors will take account of any
      corresponding savings or benefits accruing to SpaceDev or SIL as a result
      of the circumstances giving rise to the SpaceDev Warranty Claim. If any
      provision in the SpaceDev Financial Statements for taxation proves to be
      an over-provision, the amount of the over-provision will be set off
      against any liability of the SpaceDev Warrantors under this Agreement.

3.25  Subject to the other provisions of this Article 3, it is hereby agreed
      that each SpaceDev Warrantor shall have no liability in respect of any
      claim made by the SIL Shareholders for breach of any of the provisions of
      this Agreement if such claim or claims shall have arisen by reason of
      fraud, dishonesty or deliberate non-disclosure on the part of any other
      SpaceDev Warrantor.

SPECIFIC MATTERS

The following specific matters are disclosed. References in the margin are to
the Warranties contained in the corresponding clause numbers in Article 2 of the
Agreement. A document number in square parentheses is the number of the Due
Diligence Document or Disclosure Document listed in Schedule 1 or 2 to this
letter respectively:


2.7(a) FINANCIAL STATEMENTS.
       ---------------------

          DISPUTE WITH BEGBIES TRAYOR
          ---------------------------

          The 1997 financial accounts are only at 'draft' status because of an
          unresolved dispute between SIL and Begbies Traynor, who are the joint
          administrative receivers of Satellites International Limited, the
          company whose assets and business were purchased by SIL in June 1996.
          Schedule 2 Disclosure Documents [1] and [2] refer. As part of the
          original agreement. SIL purchased the goodwill of the company under a
          complex formula, where the goodwill was defined as the amount of
          excess profit accruing from the total of all pre-existing contracts
          over and above a predefined threshold. SIL made payments to the
          receiver over a period of time in respect of this expected goodwill,
          amounting to (pound)21,197. However, as time went on, it became
          apparent that there was no excess profit and hence no goodwill.
          Accordingly, SIL has demanded that the (pound)21,197 paid to the
          receiver should be repaid. At the time of disclosure, the current
          position is that the receiver has refused to pay back this amount. It
          is possible that in order to reduce legal charges, a compromise may be
          reached in due course, whereby the receiver pays back only a portion
          of the amount in dispute. The resolution of this matter has a direct
          bearing on the financial accounts for 1997.


          CASH FLOW SITUATION
          -------------------

          As explained in the Business, Plans, Schedule 1 documents [1] and [2],
          SIL has long been in need of a cash flow buffer, with an amount of
          (pound)300k being suggested as appropriate to the type of business
          undertaken by the company. One of the principal factors taken into
          account by the SIL shareholders in pursuing the Agreement with
          SpaceDev was the undertaking by SpaceDev to provide such a buffer.
          Prior to completion of the Agreement, SpaceDev has provided $80k as an
          unsecured loan. On completion of the Agreement, SIL has an immediate
          need of a further $150k in order to help smooth out the uneven cash
          flow which is inherent in this type of business. Both these amounts
          are seen as part of the $2M which will be provided by SpaceDev over
          the acquisition period.


<PAGE>

          BANK OVERDRAFT FACILITY
          -----------------------

          SIL has recently changed bankers to Lloyds Bank in Newbury. The bank
          has agreed an unsecured overdraft facility of (pound)50,000 in
          accordance with the overdraft facility letter included in Schedule 2,
          Document [3]. At present the Bank has agreed verbally to increase the
          overdraft to (pound)100k until the end of September 1998. There is
          currently no agreement for this increase to be retained beyond this
          date. This is one of the reasons for the cash injection requirement
          described above.

          FINANCIAL FORECASTS
          -------------------

          The financial forecasts included in the Business Plans, Schedule 1
          Documents [1] and [2], are based on an assessment of the potential
          market for SIL's products and do not necessarily reflect what is
          likely to be achieved due to the constraints resulting from limited
          resources in terms of manpower, equipment and facilities. The cash
          infusion from SpaceDev should minimise these constraints.



2.7(b)    NO MATERIAL ADVERSE CHANGES
          ---------------------------
          CONTRACT CHANGES
          ----------------

          There have been a number of changes to current contracts, mostly

          expected to be, contentious, but for completeness the contracts
          involved are:

          certain material assets of the Company against overdue 1997/8 PAYE and
          National Insurance payments. This order was satisfied and fully
          discharged in August 1998. The Tax Office has agreed to provide
          written confirmation that this has been done. This confirmation will
          be sent to SpaceDev as soon as it is available.


          TAX AUDIT
          ---------

          HM Customs and Excise and Inland Revenue Tax Inspectors have carried
          out their standard statutory tax audits following the Management
          Buy-Out of the original company, Satellites International Limited, in
          June 1996. No anomalies were found or recorded.

                                                                BY FAX AND BY DX

Dear Sirs

SATELLITES INTERNATIONAL LIMITED (IN ADMINISTRATIVE RECEIVERSHIP)

We act for Space Innovations Limited ("SIL"). who purchased the assets and
business of Satellites International Limited ("the Company") on 30 May 1996 from
your clients, D.R.F Sapte and F.E Watson of Begbies Traynor, acting as joint
administrative receivers of the Company.

A dispute has arisen between our respective clients as to the consideration to
be paid for the goodwill of the Company. It is our client's position that the
goodwill of the Company has nil value and therefore the full amount of
(pound)21,196.94 which it has paid on account of the purchase of the goodwill
should be reimbursed by your client.

THE RELEVANT CONTRACTUAL CAUSES

THE SALE AGREEMENT

By an Agreement dated 30 May 1996 between the Company and a shelf company which
is now SIL ("the Sale Agreement"), the Company agreed to transfer to our client
such right, title and interest as it might have in the Company and certain of
the Company's assets. The Vendor is defined as the Company acting by its Joint
Administrative Receivers and the Purchaser is the shelf company which is now
SIL. The following clauses of the Sale Agreement are relied on by our client:

(i) Clause 1.1:-

          ""Assets" Collectively the Contracts, the Goodwill,..."

(ii) Clause 2.1:-



                                                                  Continued..../


<PAGE>

          "Subject to the provisions of this Agreement, the Vendor shall sell,
          and the Purchaser shall purchase, with effect from the Transfer Date,
          such right title and interest as the Vendor may have in the Business
          and the Assets..."

(iii) Clause 3.1:-

          "The consideration for the sale, and purchase, and for the licences
          and other facilities mentioned below; shall be agreed between the
          Vendor and the Purchaser or, failing that, under clause 24 and; when
          so agreed or determined, shall be payable by the Purchaser on demand
          by the Vendor."

THE SUPPLEMENTAL AGREEMENT

By a Supplemental Agreement dated 6 June 1996 between the Company and the same
shelf company which is now SIL ("the Supplemental Agreement"), the method by
which the goodwill of the Company would be calculated and purchased was agreed.
The following clauses of the Supplemental Agreement are relied on by our client:

(i) Clause 2:-

    ""New contracts Vendor's Amounts"         The lesser of(pound)20,000 and an
                                              amount equal to the aggregate of
                                              the amount set out in column 8
                                              (WIP) of the final schedule
                                              prepared by the Purchaser to
                                              Clause 3.1.2 of Schedule 1
                                              hereto in the form of the pro
                                              forma calculation set out in
                                              Schedule 3 hereto: ["NCVA"]"

""Vendor's Amounts"                           The lesser of (pound)43,590 and an
                                              amount equal to the aggregate of
                                              the amounts to be set out in
                                              column 8 (WIP) of the final
                                              schedule prepared by the
                                              Purchaser pursuant to Clause
                                              3.1.1 of Schedule 1 hereto in the
                                              form of the pro forma
                                              calculation set out in Schedule 2
                                              hereto, ["VA"]"

The NCVA and the VA are therefore to be calculated pursuant to the pro forma
calculations respectively set out in Schedules 2 and 3 to the Supplemental
Agreement on the basis of the aggregate amounts set out in column 8 (WIP) of the
final schedules.

                                      -2-                         Continued..../

               3.1.2 a Schedule in the form of Schedule 3 showing the position
               as at the previous month end including the position on the New
               Contract's Performance Costs".

           This is consistent with the definitions of NCVA and VA set out above.

(iii)     The consideration for the Sale and Purchase of the Goodwill of the
          Company is calculated under Clause 2.2 as follows:

               "In respect of the Goodwill the sum of (pound)1 plus the Vendor's
               Amounts as at 30 November 1997 and plus the New Contracts
               Vendor's Amounts as at 30 November 1997 subject to and as
               calculated and payable in accordance with Schedule 1 hereto".

          In addition, Schedule 1 Clause 2 provides that:-

               "The Purchaser shall pay to the Vendor as consideration for the
               Goodwill (pound)1 plus a sum equal to the aggregate at the
               Vendor's Amounts as at 30 November 1997 and the New Contracts
               Vendor's Amounts as at 30 November 1997 calculated and payable in
               accordance with Clause 4 of this Schedule 1"

OUR CLIENT'S CLAIM

1.        CLAUSE 2.2

It is our view that, Clause 2.2 is subject to Schedule 1 Clause 2. Therefore,
even though Clause 2.2 does not explicitly state that the goodwill of the
Company is comprised of the sum of (pound)1 plus a sum equal to the aggregate
value of the NCVA and VA as at 30 November 1997, this is implicit because
Schedule 1 Clause 2.2 provides for an aggregation of the NCVA and the VA as at
that date.

It is also our view that either or both the NCVA or the VA may have a negative
value on the basis that the pro forma calculations set out in Schedules 2 and 3
of the Supplemental Agreement in relation to the NCVA and the VA respectively
contain negative values for a number of the amounts shown in column 8 (WIP) of
those Schedules.

The final schedule for the NCVA prepared pursuant to Clause 2 of the
Supplemental Agreement shows the aggregate of the figures in column 8 (WIP) as
(pound)42,021.


                                      -3-                         Continued..../


<PAGE>

However, the amount for the NCVA has been capped at (pound)20,000 by that
Clause.

The final schedule for the VA prepared pursuant to Clause 2 of the Supplemental
Agreement shows the aggregate of the figures in column 8 (WIP) as minus
(pound)22,843. As set out above, it is possible for this amount to be a negative
value.

The sum equal to the aggregate of these two amounts ((pound)20,000 + minus
(pound)22,343) is minus (pound)2,843.

The consideration for the purchase of the goodwill of the Company pursuant to
Clause 2,2 is therefore calculated as follows:

          consideration provided for                          (pound)
          in clauses 2,2 and
          Schedule 1 Clause 2                                      1

          sum equal to the aggregate
          of the NCVA and VA as at
          30 November 1997                                    (2,843)

          TOTAL                                               (2,842)

It is therefore our client's position that the Company has no goodwill and that
the consideration for the purchase of the goodwill of the Company pursuant to
Clause 2.2 is nil.


2.        SCHEDULE 1 CLAUSE 4

As set out above Schedule 1 Clause 2 provides that the sum equal to the
aggregate of the NCVA and VA is:-

          "Calculated and payable in accordance with Clause 4 of Schedule 1."

Schedule 1 Clause 4.1.1 provides that:-

          "The Purchaser shall make payments on account to the Vendor in six
          equal three monthly installments, the first such instalment being paid
          on 12 September 1996, and the subsequent instalments being paid at
          three monthly intervals thereafter."

Schedule 1 Clause 4.1.2 provides that:

         "The amount of each instalment shall be (pound)3,632.50 in respect of
         the Vendor's Amount and (pound)1,666.66 in respect of the New Contracts
         Vendor's Amounts".

Schedule 1 Clause 4.1.3 provides that:

          "The balance of the Vendor's Amounts and the New Contracts Vendor's
          Amounts shall be paid by the Purchaser to the Vendor or reimbursed by
          the Vendor to the Purchaser (as appropriate) on the date 28 days after
          the last of

                                       -4-

<PAGE>

          the six three month periods referred to above".

Schedule 1 Cause 4.2 then sets out a number of factors which may affect the
payment of the instalments under Schedule 1 Clause 4.1. The only provision of
Schedule 1 Clause 4.2 which our client relies upon is 4.2.1:

          "if either of the schedules produced by the Purchaser pursuant to
          clauses 3.1.1 and 3.1.2 of this Schedule 1show a position where the
          aggregate total of column 8 is less than (pound)21,795 in the case of
          that produced pursuant to clause 3.1.1 or is less than (pound)10,000
          in the case of that produced pursuant to clause 3.1.2, the Purchaser
          shall be entitled to suspend payment of the relevant instalments."

Pursuant to this clause our client withheld two instalments to be paid under
Schedule 1 Clause 4.1.2.

It is our view that the provisions for payment of the NCVA and the VA in
Schedule 1 Clauses 4.1 and 4.2 are consistent with the method of calculating the
consideration for the purchase of the goodwill of the Company under Clause 2.2
and Schedule 1 Clause 2.

Schedule 1 Clause 4.1.2 differentiates between the amount of each instalment to
be paid for the NCVA and the VA respectively. This does not prevent the
aggregation of the two amounts once the final schedules have been produced
pursuant to Clause 2. Further, Schedule 1 Clause 4.1.3 provides that the balance
of the VA and the NCVA shall be paid by the Purchaser to the Vendor or
reimbursed by the Vendor to the Purchaser "as appropriate". The use of the word
"balance" in the singular implies that one amount will either be paid by the
Purchaser or reimbursed by the Vendor when the final schedules have been
produced. The words "as appropriate" suggest that a further payment will be made
by the Purchaser if the balance of the NCVA and the VA is more than the amount
paid on account or that the Vendor will reimburse the Purchaser where the amount
paid on account is more than the balance of the NCVA and the VA. This Supports
our view that the NCVA and the VA are to be aggregated to calculate the
consideration to be paid under clause 2.2.;

THE GROUNDS FOR OUR CLIENT'S CLAIM

It is our view that our client is entitled to reimbursement of the full amount
of (pound)21,196.64 which they have paid on account for the purchase of the
goodwill of the Company.

There are two grounds on which our client's claim for the reimbursement of the
full amount paid on account is based:-

          (i)     As the goodwill of the Company is nil, as calculated above,
                  your client is under a contractual obligation pursuant to
                  Schedule 1 Clause 4.1.3 to reimburse to our client the full
                  amount it has paid on account of the purchase of the goodwill.
                  Your client is in breach of that obligation.

          (ii)    Pursuant to Clause 2,1 of the. Sale Agreement your client is
                  under a

                                       -5-


<PAGE>

                  contractual obligation to sell its right, title and interest
                  in the assets of the Company, which includes its goodwill. Our
                  client has paid (pound)21,196.64 on account of the purchase of
                  the goodwill. The Company has no goodwill therefore our client
                  has received nothing in return for this payment. Your client
                  is therefore in breach of its obligations under, inter alia,
                  Clause 2.1 of the Sale Agreement.

Please confirm that within 14 days of the date of this letter that your client
will reimburse the full amount of (pound)21,196.64 to our client plus interest
under Clause 7 of the Supplemental Agreement. In the event that we do not
receive your confirmation by the above time limit we will advise our client to
commence proceedings against your client. -

Yours faithfully

File No. 3-9668



In the Matter of                             ORDER INSTITUTING PUBLIC
Spacedev, Inc.                               CEASE-AND-DESIST
and James W. Benson,                         PROCEEDINGS PURSUANT TO
                                             SECTION 8A OF THE
Respondents.                                 SECURITIES ACT OF 1933
                                             AND SECTION 21C
                                             OF THE SECURITIES
                                             EXCHANGE ACT OF 1934

                                       I.

          The Securities and Exchange Commission ("Commission") deems it
appropriate and in the public interest that public cease-and-desist proceedings
be, and they hereby are, instituted pursuant to Section 8A of the Securities Act
of 1933 ("Securities Act") and Section 21C of the Securities Exchange Act of
1934 ("Exchange Act") against Spacedev, Inc. ("Spacedev") and James W. Benson
("Benson").

                                       II.

          As the result of an investigation, the Division of Enforcement ("the
Division") alleges that:

A. Spacedev, Inc. is a publicly-held Colorado corporation headquartered in San
Diego, California. Spacedev is the surviving corporation of the October 1997
merger between a privately-held, Colorado-based holding company named Spacedev,
LLC, and a Colorado shell company named Pegasus Development Group, Inc. In
approximately April 1998, Spacedev made a public offering of its stock pursuant
to Rule 504 of Regulation D under the Securities Act. At all relevant times
Spacedev's common stock was quoted on the OTC Bulletin Board.

B. James W. Benson, age 53, who maintains residences in both Virginia and
Colorado, has been chairman of Spacedev's board of directors since the company's
inception.



<PAGE>

C. Spacedev proposes to engage in the business of commercial space exploration
and development. The company intends to construct and launch an unmanned
spacecraft (the Near Earth Asteroid Prospector or "NEAP") to a targeted near
earth asteroid for the purpose of collecting scientific data. Spacedev intends
to obtain revenue from this project by selling space on the NEAP module to
scientists seeking to transport their own instruments to the asteroid, and by
selling data obtained by instruments attached to the NEAP module by Spacedev.
Spacedev plans to launch the NEAP module no earlier than 2000.

D. From about January 1998 through June 1998, Benson and Spacedev violated
Section 17(a) of the Securities Act and Section 10(b) of the Exchange Act and
Rule l0b-5 thereunder in that, directly or indirectly, in or in connection with
the offer, purchase or sale of securities by use of the means or
instrumentalities of transportation or communication in interstate commerce or
by use of the mails, they employed devices, schemes or artifices to defraud;
obtained money or property by means of untrue statements of material facts or
omissions to state material facts necessary in order to make the statements
made, in the light of the circumstances under which they were made, not
misleading or engaged in transactions, practices, or courses of business which
would or did operate as a fraud or deceit upon the sellers and purchasers of
securities, namely common stock of Spacedev.

E. As a part of and in furtherance of the conduct described above in
subparagraph II.D., from approximately January 1998 through June 1998, in press
releases, a newsletter, and over the internet, Spacedev and Benson made untrue
statements of material facts and omitted to state material facts to the public,
to investors and to prospective investors, including those in the Rule 504
offering. In this regard, Spacedev and Benson:

          1. Projected for 1998 revenues of $l0 million and earnings of $2
million. These projections had no reasonable basis and were false and misleading
because Benson and Spacedev did not disclose numerous contingencies to its
revenue projections, such as the need for approval of its potential customers'
projects by the National Aeronautics and Space Administration ("NASA");

          2. Falsely stated that Spacedev had an agreement with NASA for the use
of its Deep Space Network, a satellite communication system necessary to
accomplish Spacedev's NEAP mission; and

          3. Misrepresented the nature of Spacedev's financing agreement with a
broker-dealer, and continued to publicly assert the existence of the agreement
after it was terminated.

                                      III.

          In view of the allegations made by the Division, the Commission deems
it necessary and appropriate in the public interest that public cease and desist
proceedings be instituted to determine:

A. Whether the allegations set forth in Section II hereof are true and, in
connection therewith, to afford the Respondents an opportunity to establish any
defenses to such allegations; and

                                       2


<PAGE>


B. Whether, pursuant to Section 8A of the Securities Act and Section 21C of the
Exchange Act, the Respondents should be ordered to cease and desist from
committing or causing violations of and any future violations of Section 17(a)
of the Securities Act and Section 10(b) of the Exchange Act and Rule 10b-5
thereunder.

                                       IV.

          IT IS HEREBY ORDERED that a public hearing for the purpose of taking
evidence on the questions set forth in Section III hereof be convened not
earlier than thirty (30) days and not later than sixty (60) days from service of
this Order, at a time and place to be fixed, and before an Administrative Law
Judge to be designated, by further Order as provided by Rule 200 of the
Commission's Rules of Practice, 17 C.F.R. ss. 201.200.

          IT IS FURTHER ORDERED that Respondents file an Answer to the

                  SPACEDEV CEO ISSUES STATEMENT ON SEC INQUIRY

San Diego, CA - Jim Benson, SpaceDev (OTC BB: SPDV) founder and president,
responded today to a Securities and Exchange Commission (SEC) administrative
proceeding filed on Thursday, August 6, 1998.

"SpaceDev was disappointed to learn that the SEC has decided to institute an
administrative proceeding," said Mr. Benson. "While the Company disagrees with
the views expressed by the SEC in its Order Instituting Proceedings, the Company
had attempted to resolve the issues raised by the SEC through a settlement. The
Company now intends to vigorously contest the SEC's allegations."

Mr. Benson compared today's action by the SEC to "shooting at ants with an
elephant gun," and expressed confidence that ultimately the SEC's case would be
dismissed and that the Company would be vindicated.

SpaceDev, the world's first commercial space exploration and development
company, intends to launch the first privately financed spacecraft to land on
another planetary body. SpaceDev is selling rides for scientific instruments to
governments and companies to transport their instruments and experiments,
through deep space to a near earth asteroid. SpaceDev intends to sell the data
acquired by its instruments as commercial products. Colorado-based SpaceDev has
offices in San Diego, CA and Washington, D.C.

EXCEPT FOR HISTORICAL FINANCIAL INFORMATION CONTAINED HEREIN, THE MATTERS SET
FORTH IN THIS RELEASE ARE FORWARD-LOOKING STATEMENTS THAT ARE DEPENDENT ON
CERTAIN RISKS AND UNCERTAINTIES INCLUDING BUT NOT LIMITED TO SUCH FACTORS AS
MARKET DEMAND PRICING, AND CHANGES IN WORLDWIDE ECONOMIC CONDITIONS.

                   MUTUAL RELEASE AND RESCISSION OF AGREEMENT


         This MUTUAL RELEASE AND RESCISSION OF AGREEMENT, (the "Agreement")
executed on December 17, 1999, between:

         (i)    Space Innovations Limited, a company incorporated in England and
                Wales, ("SIL") of The Paddock,  Hambridge Road, Newbury,
                Berkshire RG14, England;

         (ii)   Persons whose names and address are shown in Exhibit A ("Former
                SIL Shareholders");

         (iii)  SpaceDev, Inc., a company incorporated in Colorado, U.S.A.,
                ("SpaceDev") of 13855 Stowe Dr., Poway, California, U.S.A.; and

         (iv)   James W. Benson, an individual

         The purposes of this Agreement is intended to effect the extinguishment
of obligations as herein designated.

                                    RECITALS

         WHEREAS, Disputes and differences have arisen between the above
referenced Parties with respect to that certain agreement in writing entered
into between the parties on or about October 1, 1998, and entitled "Common Stock
Exchange Agreement" (hereinafter the "Stock Agreement"). Said Stock Agreement is
incorporated by reference, and is hereby made a part of this release;

         WHEREAS, The parties desire to resolve their disputes and differences,
and wish to express their interest in working to cooperatively develop mutually
beneficial and positive future working relations;

         WHEREAS, The parties recognize that the principal basis for the
disputes and differences underlying this Agreement relate to statutory and
regulatory rules, including those statutes and regulations concerning the
transfer of technology overseas and as between parent and subsidiary
corporations, which adversely effect the ability of the Parties to realize the
benefits contemplated upon execution of the Stock Agreement;

         WHEREAS, The parties have agreed to execute this Agreement in
settlement of such disputes and differences with the intent to allow SpaceDev
and SIL to separately continue their business and operations.

         WHEREAS, The parties accept that various aspects of the Stock Agreement
have not been performed including the fact that SpaceDev has not been registered
as the holder of the shares in SIL and SpaceDev has not delivered shares to
former SIL shareholders in accordance with the Stock Agreement. Also SIL shares
have not been forwarded to SpaceDev in accordance with the Stock Agreement.

                                    ARTICLE 1
                                     RELEASE

         1.1 In consideration of the mutual relinquishment of their respective
legal rights with reference to the above-mentioned disputes and differences, and
in consideration of the execution of this mutual release, covenants by the
parties and the payment of Two-Hundred and Eight Thousand pounds
((pound)208,000.00 U.K.) according to the terms of the Secured Promissory Note
attached as Exhibit B and incorporated herein by this reference, each Party
expressly releases the other, together with its officers, directors, employees,
trustees, successors, assigns, agents, employees and legal representatives, from
all liability for claims and demands arising out of the Stock Agreement or out
of the management or operation of SpaceDev or SIL up to the date of this
Agreement.

         1.2 The Parties acknowledge that they may hereafter discover facts in
addition to or different from those which they now know or believe to be true
with respect to the Stock Agreement, or the subject matter of this Agreement,
but it is their intention to fully and finally and forever settle and release
all matters, disputes and differences, known and unknown, suspected and
unsuspected, which now exist, may exist or heretofore have existed between them.
In furtherance of this intention, the releases herein shall be and will remain
in effect as full and complete general releases, except as otherwise provided
herein, notwithstanding the discovery or existence of any such additional or
different facts.

                                    ARTICLE 2
                      RESCISSION OF CONTRACT AND COVENANTS

         2.4 All proprietary information, IPR and all technical documentation
previously supplied to SpaceDev or SIL and copies thereof, shall be returned to
the originating party within ten (10) days from the date first written above.

                               GENERAL PROVISIONS

         3.1 In entering and making this Agreement, the Parties assume the risk
of any mistake of fact or law. If the Parties, or any of them, should later
discover that any fact they relied upon in entering this Agreement is not true,
or that their understanding of the facts or law was incorrect, the Parties shall
not be entitled to seek rescission of this Agreement by reason thereof. This
Agreement is intended to be final and binding upon the Parties regardless of any
mistake of fact or law.

         3.2 Neither the negotiation nor the execution of this Agreement, nor
anything contained or incorporated herein shall be deemed or otherwise alleged
to constitute, any admission or concession of liability or wrongdoing on the
part of any Party, or any other form of admission with respect to any matter,
thing or dispute whatsoever. Any such liability or wrongdoing is expressly
denied.

         3.3 Each Party warrants that it is represented by competent counsel
with respect to this Agreement and all matters covered by it, and it has been
fully advised by said counsel with respect to its rights and obligations and
with respect to the execution of this Agreement. SIL and the former SIL
Shareholders are not conversant on California Laws.

         3.4 Each Party warrants that no promise, inducement or agreement not
expressed herein has been made in connection with this Agreement. This Agreement
constitutes the entire agreement between the Parties and supercedes and replaces
all prior negotiations or proposed agreements, written or oral.

         3.5 This Agreement may not be altered, amended, modified or otherwise
changed in any respect whatsoever except by a writing duly executed by an
authorized representative of each of the Parties.

         3.6 The language of this Agreement shall be construed as a whole,
according to its fair meaning and intendment, and not strictly for or against
any Party, regardless of who drafted or was principally responsible for drafting
the Agreement or any specific term or condition hereof. This Agreement shall be
deemed to have been drafted by all Parties, and no Party shall urge otherwise.

                                       3
<PAGE>

         3.7 The headings in this Agreement are for convenience only. They in no
way limit, alter or affect the meaning of this Agreement.

         3.8 This Agreement shall be construed and enforced pursuant to the laws
of the State of California and SpaceDev warrants that this Agreement is assumed
enforceable under California laws.

         3.9 Should any provision of this Agreement be held illegal, such
illegality shall not invalidate the whole of this Agreement; instead, the
Agreement shall be construed as if it did not contain the illegal part, and the
rights and obligations of the Parties shall be construed and enforced
accordingly.

         3.10 This Agreement may be executed in multiple originals, each of
which is equally admissible in evidence and shall be deemed to be one and the
same instrument. This Agreement shall not take effect until each Party has
signed a counterpart. It shall only be necessary to produce one of such
counterpart in making proof of this Agreement. It is further agreed that a
facsimile signature shall be deemed an original.

         3.11 Each Party shall pay its own expenses incident to the transaction
contemplated by this Agreement, including but not limited to the fees, expenses
and disbursements of their respective advisors, accountants and counsel.
Further, each Party shall pay its own costs, including any regulatory costs, tax
or duty associated with the transfer or cancellation of any shares contemplated
by this Agreement.

         3.12 Each Party represents and warrants that it has the full power and
authority to enter into this Agreement and to perform all transactions, duties
and obligations herein set forth. Each signatory to this Agreement who signs on
behalf of a Party represents and warrants that he or she has the authority to
sign on behalf of that Party.

         3.13 Each Party recognizes that certain Former SIL Shareholders who are
intended signatories to this Agreement currently live abroad, outside of the
United States and/or the United Kingdom. Further, each Party recognizes that
receipt of the signatures from said Former SIL Shareholders may delay execution
of the agreement by all Parties, and that accordingly provisions are
appropriately made to address and ameliorate the effects of any delay.
Therefore, the following additional representations and agreements are made.

                  a) SIL represents, by and through the signature of its agent
below, that all Former SIL Shareholders approve of this Agreement, including all
those Former SIL Shareholders living abroad and/or those whose signatures are
not obtained by Friday, December 17, 1999. Further, SIL represents it will
exercise its best efforts to secure the signatures of all Former SIL
Shareholders, including those living abroad, and that said signatures shall be
obtained by SIL, at its expense, no later than 12:00 am Greenwich, England time
December 24, 1999. Until such time as SIL is able to obtain signatures from all
Former SIL Shareholders, SIL agrees that it will not recapitalize, or offer any

                                       4
<PAGE>

shares of its stock for sale without the express written consent SpaceDev.
Such consent from SpaceDev shall not be unreasonably withheld.

                  b) Each Party signing this Agreement, whether such signature
is provided in an individual or representative capacity, agrees to be bound and
beholden to the Agreement as against every other Party who has signed this
Agreement, notwithstanding the absence of the signature(s) of one or more Former
SIL Shareholders; provided however that this provision shall remain ineffective
until SIL, SpaceDev and a majority of Former SIL Shareholders have signed this
Agreement.

         3.14 On or about the execution date of this Agreement, SpaceDev shall
issue a press release or make a public statement concerning the mutual release
and rescission of the Stock Agreement which shall be previously agreed by SIL as
to its contents and wording. Neither party shall make any announcement of such
transaction or disclose the existence of and/or particulars of any negotiations
related thereto, including, but not limited to, the terms, conditions, or other
facts related to this Agreement or the Stock Agreement without the express
written approval and consent of the other parties. The former SIL Shareholders
hereby authorize SIL to give such consent on their behalf. Notwithstanding the
above condition, should SpaceDev reasonably believe that any information
regarding this Agreement or its prior dealings with SIL must be disclosed due to
SEC Regulations or Rulings, in the sole interpretation of SpaceDev, then
SpaceDev shall be entitled to make any such required public announcement without
the requirement of written consent of SIL. Notwithstanding the above condition,
should SIL reasonably believe that any information regarding this Agreement or
its prior dealings with SpaceDev must be disclosed due to any United Kingdom
Regulations or Rulings, in the sole interpretation of SIL, then SIL shall be
entitled to make any such required public announcement without the requirement
of written consent of SpaceDev.

         3.15 Upon the execution of this Agreement, the Parties agree that it
shall not make any defamatory or disparaging statements, either orally or in
writing, about the parties to this Agreement, its businesses, products and
services or officers or directors of the parties or affiliates or subsidiaries.
The word "disparage" shall mean making comments to a person not a party to this
Agreement which would be actionable under legal principles of defamation or
which may materially cause damage to the reputation of a party to this
Agreement.

         IN WITNESS HEREOF, each of the parties hereto has caused this Agreement
to be executed by its duly authorized officers as of the day and year first
written above.

make the required payment within thirty (30) days, then, without further notice
to Maker, Holder may declare the Note due in full and take the appropriate
action deemed by Holder to be in its best interest to enforce the terms of this
Note. Waiver of the right to so accelerate the maturity of obligations hereunder
will be effective only if set forth in a written instrument signed by Holder;
failure to exercise, or delay in exercising, the right will not be construed as
a waiver of the right.

assess. Maker acknowledges that a sum equal to 4% of the late payment is, under
the circumstances existing at the time this Note is made, a reasonable late
charge, and Maker will pay the late charge when due. The late charge will become
immediately due ten (10) days after the mailing to Maker, or any other person
known by Holder to be liable for the payment of this Note, of written notice of
the delinquency of the payment.

judicial action or nonjudicial proceeding commenced by any person concerning
this Note. Maker will pay reasonable attorneys' fees.

and working papers produced or developed by the Auditors or management in

such reports and working papers for prior periods for which any tax liability of
SpaceDev has not been finally determined or barred by applicable statutes of
limitation. Since October 31, 1997, there has been no change in any of the
significant accounting policies, practices or procedures of SpaceDev.

                  (b) NO MATERIAL ADVERSE CHANGES. Except as set forth at end of

                  Material Adverse Effect.

                         ii.    any agreement, condition, action or omission
                  which would be proscribed by (or require consent under)

                  of this Agreement,

                         iii.   any strike or other labor dispute, or

                         iv.    any casualty, loss, damage or destruction

                  (c) NO OTHER LIABILITIES OR CONTINGENCIES. To the best of
SpaceDev's knowledge, SpaceDev does not have any liabilities of any nature,

Closing Date, all Tax Returns required to be filed by it on or before the
Closing Date and has paid all Taxes due for all periods ending on or before

delivered to the ISS Shareholders, for all Taxes relating to operations through,
or property owned on or before, the date of the most recent of such financial
statements. No liability for Taxes has arisen since such date other than in the
ordinary course of SpaceDev's business. All required Tax Returns including
amendments to date, have been prepared in good faith without negligence or
willful misrepresentation and are complete and accurate in all material
respects. No Governmental Entity has, during the past two years, examined or is
in the process of examining any Tax Returns of SpaceDev. No Governmental Entity

thereunder to the extent that such obligations to perform have accrued; and no

default thereunder by SpaceDev or, to the best knowledge of SpaceDev, by any
other party or obligor with respect thereto, has occurred or as a result of this
Agreement or performance will occur. Consummation of the transactions
contemplated by this Agreement will not (and will not give any Person a right
to) terminate or modify any rights of, or accelerate or augment any obligation
of SpaceDev under any Material Contract.

Actions has or might reasonably be expected to have a Material Adverse Effect,

of the transactions contemplated by this Agreement. There is no matter as to
which SpaceDev has received any notice, claim or assertion, or, to the best
knowledge of SpaceDev, which otherwise has been threatened against or affecting
any director, officer, employee, agent or representative of SpaceDev or any
other Person, in connection with which any such Person has or may reasonably be

from the date of this Agreement to the Closing Date and (ii) any failure of
SpaceDev or ISS, as the case may be, to comply with or satisfy, in any material
respect, any covenant, condition or agreement to be complied with or satisfied
by it under this Agreement. Except as provided in Section 7.4, no such

the conditions to their respective obligations hereunder.

connection with the transactions contemplated by this Agreement, ISS and the ISS
Shareholders and SpaceDev shall each use best efforts to obtain such Approval
prior to the Closing Date.

                      TERMINATION OF OBLIGATIONS; SURVIVAL

         7.1      Termination of Agreement.
                  -------------------------

                  Anything herein to the contrary notwithstanding, this
Agreement and the transactions contemplated by this Agreement shall terminate if
the Closing does not occur on or before the close of business on February 18,
1998, unless extended by mutual consent in writing of SpaceDev and the ISS
Shareholders and otherwise may be terminated at any time before the Closing as
follows and in no other manner:

                  (a) MUTUAL CONSENT. By mutual consent in writing of SpaceDev
and the ISS Shareholders.

                  (b) CONDITIONS TO SPACEDEV'S PERFORMANCE NOT MET. By
SpaceDev's written notice to the ISS Shareholders if any event occurs or
conditions exists which would render impossible the satisfaction of one or more
conditions to the obligations of SpaceDev to consummate the transactions
contemplated by this Agreement as set forth in Section 6.1 or 6.2.

                  (c) CONDITIONS TO THE ISS SHAREHOLDERS' PERFORMANCE NOT MET.
By the ISS Shareholders' written notice to SpaceDev if any event occurs or
condition exists which would render impossible the satisfaction of one or more
conditions to the obligation of the ISS Shareholders to consummate the
transactions contemplated by this Agreement as set forth in Section 6.1 or 6.3.

                  (d) INACCURATE INFORMATION. By SpaceDev if any material
information expressly required by this Agreement or the Disclosure Schedule to
be delivered by or on behalf of ISS and the ISS Shareholders to SpaceDev is
inaccurate or incomplete in any material respect.

                  (e) MATERIAL BREACH. By SpaceDev or the ISS Shareholders if
there has been a material misrepresentation or other material breach by the
other party in its representations, warranties and covenants set forth herein;

         7.2      Effect of Termination.
                  ----------------------

                  In the event that this Agreement shall be terminated pursuant
to Section 7.1, all further obligations of the parties under this Agreement
shall terminate without further liability of any party to another; provided that
the obligations of the parties contained in Article 8, Section 9.9 and Section
9.12 shall survive any such termination. A termination under Section 7.1 shall
not relieve any party of any liability for a breach of, or for any
misrepresentation under, this Agreement, or be deemed to constitute a waiver of
any available remedy (including specific performance if available) for any such
breach or misrepresentation.

         7.3      Survival of Representations and Warranties.
                  -------------------------------------------

                  The representations and warranties contained in or made
pursuant to this Agreement shall survive the Closing and expire at the end of 18
full calendar months after the Closing, except that (i) the representations and
warranties contained in Section 2.1, 2.2, 2.8, 2.17, 3.1, 3.2 and 3.3 shall
survive the Closing and shall remain in full force and effect indefinitely, (ii)
the representations and warranties contained in Section 2.4 and 3.8 shall
continue through the expiration of the applicable statute of limitations as the
same may be extended (or, if a claim has been asserted prior to such expiration,
until 90 days after the date of its final resolution), and (iii) if a claim or
notice is given under Article 8 with respect to any representation or warranty
prior to the applicable expiration date, such representation or warranty shall
continue, with respect to the facts or circumstances giving rise to such claim,
indefinitely until such claim is finally resolved.

         7.4      Effect of Closing Over Known Unsatisfied Conditions.
                  ----------------------------------------------------

                  If, with actual knowledge of the failure of any condition or
breach of any representation and warranty, either SpaceDev or any of the ISS
Shareholders elects to proceed with the Closing, the condition that is
unsatisfied at the Closing Date shall be deemed to be waived and the electing
party shall so acknowledge by a writing delivered at the Closing; provided,
however, that the foregoing provision shall not limit any party's right not to
waive any condition or right to condition any waiver hereunder upon mutually
acceptable conditions. Such decision and writing shall constitute a waiver of
any liability for breach of or misrepresentation under this Agreement, but only
with respect to, and such waiver shall be limited to the extent of, the facts or
circumstances, actually known by the electing party, giving rise to or in
respect of such waived condition.

<PAGE>

         8.1      Obligations of SpaceDev.
                  ------------------------

                  SpaceDev shall indemnify and hold harmless the ISS
Shareholders from and against any and all Losses of the ISS Shareholders,
directly or indirectly, as a result of, or based upon or arising from:

                  (a) any inaccuracy in or breach or nonperformance of any of
the representations,  warranties, covenants or agreements made by SpaceDev in or
pursuant to this Agreement; or

                  (b) any other matter as to which SpaceDev in other provisions
of this Agreement has agreed to indemnify the ISS Shareholders.

         8.2      Obligations of the ISS Shareholders.
                  ------------------------------------

                  ISS shall indemnify and hold harmless SpaceDev, its officers,
directors, employees, affiliates, agents and assigns (collectively "SpaceDev
Persons") from and against any Losses of the SpaceDev Persons, directly or
indirectly, as a result of, or based upon or arising from, any inaccuracy in or
breach or nonperformance of any of the representations, warranties, covenants or
agreements made by the ISS Shareholders in or pursuant to this Agreement.

         8.3      Procedure.
                  ----------

                  (a) NOTICE. Any party seeking indemnification with respect to
any Loss shall give notice to the Indemnifying Party.

                  (b) DEFENSE. If any claim, demand or liability is asserted by
any third party against any Indemnified Party, the Indemnifying Party shall,
upon the written request of the Indemnified Party, defend any actions or
proceedings brought against the Indemnified Party in respect of matters embraced
by the indemnity, but the Indemnified Party shall have the right to conduct and
control the defense, compromise or settlement of any Indemnifiable Claim if the
Indemnified Party chooses to do so, on behalf of and for the account and risk of
the Indemnifying Party who shall be bound by the result so obtained to the
extent provided herein; provided, however, that the Indemnified Party shall not
settle or compromise any Indemnifiable Claim without the written consent of the
Indemnifying Party, which consent shall not be unreasonably withheld. If, after
a request to defend any action or proceeding, the Indemnifying Party neglects to
defend the Indemnified Party, a recovery against the latter suffered by it in
good faith, is conclusive in its favor against the Indemnifying Party; provided,
however, that, if the Indemnifying Party has not received reasonable notice of
the action or proceeding against the Indemnified Party, or is not allowed to
control its defense, judgment against the Indemnified Party is only presumptive
evidence against the Indemnifying Party. The parties shall cooperate in the
defense of all third party claims which may give rise to Indemnifiable Claims
hereunder. In connection with the defense of any claim, each party shall make
available to the party controlling such defense, any books, records or other
documents within its control that are reasonably requested in the course of such
defense.

<PAGE>

                  (c) TAX ADJUSTMENTS. Any amount payable by the Indemnifying
Party to or on behalf of an Indemnified Party in respect of a Loss shall be
adjusted as follows:

                           (i) If such Indemnified Party is liable for any
                  additional Taxes as a result of the payment of amounts in
                  respect of an Indemnifiable Claim, the Indemnifying Party will
                  pay to the Indemnified Party in addition to such amounts in
                  respect of the Loss within 10 days after being notified by the
                  Indemnified Party of the payment of such liability (x) an
                  amount equal to such additional Taxes (the "Tax Reimbursement
                  Amount") plus (y) any additional amounts required to pay
                  additional Taxes imposed with respect to the Tax Reimbursement
                  Amount and with respect to amounts payable under this clause
                  (y), with the result that the Indemnified Party shall have
                  received from the Indemnifying Party, net of the payment of
                  Taxes, an amount equal to the Loss.

                           (ii) The Indemnified Party shall reimburse the
                  Indemnifying Party an amount equal to the net reduction in any
                  year in the liability for payment of Taxes (that are based
                  upon or measured by income) of the Indemnified Party or any
                  member of a consolidated or combined tax group of which the
                  Indemnified Party is, or was at any time, part, which
                  reduction has been actually realized with respect to any
                  period after the Closing Date and which reduction would not
                  have been realized but for the amounts paid (or any audit
                  adjustment or deficiency with respect thereto, if applicable)
                  in respect of a Loss, or amounts paid by the Indemnified Party
                  pursuant to this paragraph (a "net Tax Benefit"). The amount
                  of any Net Tax Benefit shall be paid not later than 15 days
                  after the date on which such Net Tax Benefit shall be
                  realized.

                  (d) INTEREST. Any amounts payable by the Indemnifying Part to
or on behalf of an Indemnified Party in respect of a Loss shall be paid together
with interest on such amount, from and including date of Loss to the date of
payment, at a rate equal to the Prime Rate; provided, however, that such
interest shall not be payable with respect to Losses which include an interest
factor.

         8.4      Notice of Discovered Liabilities.
                  ---------------------------------

                  The Parties hereto agree to notify each other of any
liabilities, claims or misrepresentations, breaches or other matters covered by
this Article 8 upon discovery or receipt of notice thereof whether before or
after Closing.

         8.5      Not Exclusive Remedy.
                  ---------------------

                  This Article 8 shall not be deemed to preclude or otherwise

event, the Indemnifying Party shall be responsible for the full amount of any
Loss.

Rights"). The License Rights may only be canceled pursuant to the termination of
this Agreement as provided in Section 8 hereof.

          4. THE CONSIDERATION.
             ------------------

             4.1. In exchange for the license and transfer of Technology as
provided herein, SpaceDev shall pay the following Consideration (the
"Consideration") to Voorhees:

                  4.1.1. WARRANTS ON EXECUTION. On the execution of this
Agreement, SpaceDev shall issue to Voorhees Warrants to purchase twenty-five
thousand (25,000) shares of SpaceDev common stock, par value $.0001 per share
(the "Common Stock").

                  4.1.2. CONTINUING WARRANTS. For the first three (3) years of
this Agreement, Voorhees shall receive the greater of the Warrants described in
subparagraphs 4.1.2.1 or 4.1.2.2 below. Commencing with the fourth year of this
Agreement, Voorhees shall only receive the Warrants described in subparagraph
4.1.2.1 below.

                         4.1.2.1. REVENUE WARRANTS. A warrant to purchase one
(1) share of Common Stock for each one hundred and twenty-five dollars ($125.00)
in Revenue (as defined herein) earned by SpaceDev from the license, sale, use or
other disposition of the Technology. For purposes of this Agreement, "Revenue"
shall mean the income (as determined pursuant to GAAP) received from the
license, sale, use or other disposition of the Technology whether or not
pursuant to the terms of any oral or written agreement, contract or relationship
(a "Contact") between SpaceDev and a third party in which the Technology is part
of the product or service provided. SpaceDev agrees to set forth in each
Contact, if written, a line item description of each product or service sold and
the price charged for each line item setting out the price for the sale or use
of the Technology. The calculation of Revenue will be completed each calendar
quarter, commencing on the first full calendar quarter after the execution of
this Agreement, based on a review of all Contracts by SpaceDev, and if so
requested, by Voorhees.

                         4.1.2.2. ANNUAL WARRANTS. Warrants to purchase
twenty-five thousand (25,000) shares of SpaceDev Common Stock on the first three
(3) annual anniversaries of the execution of this Agreement.

             4.2. MAXIMUM CONSIDERATION. The total Consideration paid pursuant
to this Agreement shall not exceed (1) Warrants to purchase three million
(3,000,000) shares of Common Stock, or (ii) six million dollars ($6,000,000) in
Recognized Value. "Recognized Value" shall mean the sum of (a) the cumulative
difference between the Market Price (as defined herein) of the Common Stock and
the Strike Price (as defined herein) for each Warrant then owned by Voorhees,
and (b) the cumulative difference between the Market Price on the date of

                                        2
<PAGE>

exercise and the Strike Price for each Warrant previously exercised by Voorhees.
The parties will compute the Recognized Value each time Warrants are due to be
issued under this Agreement to determine if the Maximum Consideration has been
reached. "Market Price" shall mean the average of the daily closing prices of
the Common Stock on the Nasdaq Stock Exchange or such other national or regional
stock exchange or over the counter market on which the Common Stock is then
traded for the ten (10) trading days prior to the date on which the Market Price
is being determined. In the event that Recognized Value or Market Price shall be
determined in connection with a Change in Control (as defined herein) the Market
Price shall be determined as of the date ninety (90) days prior to public
knowledge of such Change in Control.

             4.3. MAXIMUM PAYOUT TERM. The Consideration shall be deemed paid in
full and all sums due to Voorhees under this Agreement shall be deemed satisfied
on the tenth anniversary of this Agreement, even if the Maximum Consideration
described in Section 4.2 has not been paid by this date.

             4.4. TERMS OF THE WARRANTS. All of the Warrants issued pursuant to
this Agreement shall be substantially in the form attached hereto as SCHEDULE B.
All Warrants issued under this Agreement will be immediately exercisable and
will expire on the fifth anniversary of their issuance. The exercise price for
the Warrants (the "Strike Price") shall be an amount equal to fifty percent
(50%) of the Market Price on the date such Warrant is issued.

             4.5. PROTECTION AGAINST DILUTION. The Strike Price for the shares
of Common Stock and number of shares of Common Stock issuable upon exercise of
the Warrants is subject to adjustment from time to time as provided in the
Warrant attached hereto as Schedule B.

             4.6. FUTURE EQUITY FINANCING. In the event SpaceDev seeks
additional equity financing in the public or private market at a price below the
Strike Price with respect to any Warrants then owned by Voorhees, SpaceDev
agrees to allow Voorhees a right to participate in that financing up to
Voorhees's percentage ownership in the Company on a fully diluted basis.

             4.7. STATUTORY WARNING. THE WARRANTS THAT ARE BEING ISSUED BY
SPACEDEV AS THE CONSIDERATION FOR THIS AGREEMENT ARE SECURITIES AS DEFINED BY
THE SECURITIES ACT OF 1933, AS AMENDED. THE WARRANTS AND THE COMMON STOCK THAT

          6. WARRANTIES.

             6.1. SpaceDev acknowledges that it has conducted a thorough review
of all aspects of the Technology. Voorhees makes no representations or
warranties concerning the Technology and licenses and transfers the Technology
to SpaceDev all faults. Voorhees shall have no duty to indemnify SpaceDev with
respect to the Technology or with respect to any use that SpaceDev may make
thereof.

          7. CONFIDENTIAL TREATMENT OF INFORMATION.

             7.1. SpaceDev covenants and agrees that any of the trade secrets

containing Confidential Information which SpaceDev may receive shall be returned
to Voorhees upon request. To that end, and without limiting the generality of
the foregoing provision, SpaceDev agrees to cause all written materials and
other documents relating to or containing Confidential Information, including
all sketches, drawings, reports and notes, and all copies, reprints, and
reproductions, to be plainly marked to indicate the secret and confidential

             8.1. TERMINATION BY VOORHEES. Voorhees reserves the right in his
sole discretion to cancel this Agreement and terminate all License Rights
granted hereunder if SpaceDev has not received Revenue (as defined herein) in
the sum of three million five hundred thousand dollars ($3,500,000) on or before

Voorhees a number of Warrants or shares of Common Stock equal to the difference
between 3,000,000 shares and the number of shares of Common Stock issuable upon
exercise of the Warrants then owned by Voorhees or previously exercised by
Voorhees. "Change in Control" shall mean any reorganization or consolidation of
SpaceDev with, or any merger of SpaceDev with or into, another entity (other

or an agent, shareholder or investor of any other corporation, directly or
indirectly, own, manage, operate, join, control or participate in the ownership,
management, operation, or control of, or consult with, or permit the use of
their name by, or be conducted in any manner with, any technology which directly
or indirectly competes with the Technology.

             10.2. The provisions of and enforcement of this section 10 will be

<PAGE>

               3.2. In the event of any exercise of the rights represented by
this Warrant, a certificate or certificates for the shares of Common Stock so
purchased, registered in the name of the Holder, or its nominee or other party

Holder within sixty (60) business days after the date in which the rights
represented by this Warrant shall have been so exercised; and, unless this
Warrant has expired or has been exercised in full, a new Warrant representing
the number of shares (except a remaining fractional share), if any, with respect
to which this Warrant shall not then have been exercised shall also be issued to
the Holder within such time.

               3.3. The person in whose name any certificate for shares of
Common Stock is issued upon exercise of this Warrant shall for all purposes be
deemed to have become the Holder of record of such shares on the date on which
this Warrant was surrendered and payment of the Warrant Price, except that, if

books of the Corporation are closed, such person shall be deemed to have become
the Holder of such shares at the close of business on the next succeeding date
on which the stock transfer books are open. No fractional shares shall be issued
upon exercise of this Warrant and no payment or adjustment shall be made upon
any exercise on account of any cash dividends on the Common Stock issued upon

          4. PROTECTION AGAINST DILUTION. The Exercise Price for the Common
Stock and number of shares of Common Stock issuable upon exercise of the
Warrants is subject to adjustment from time to time as follows:

               4.1. DIVIDENDS, SUBDIVISIONS, RECLASSIFICATIONS, ETC. In case at
any time or from time to time after the date of this Warrant, the Corporation
shall (i) take a record of the holders of the Common Stock for the purpose of
entitling them to receive a dividend or a distribution on the Common Stock
payable in Common Stock or other class of securities, (ii) subdivide or
reclassify its outstanding shares of Common Stock into a greater number of
shares, or (iii) combine or reclassify its outstanding Common Stock into a
smaller number of shares, then, and in each such case, the Exercise Price in
effect at the time of the record date for such dividend or distribution or the
Effective date of such subdivision, combination or reclassification shall be
adjusted in such a manner that the Exercise Price for the shares issuable upon
exercise of the Warrants immediately after such event shall bear the same ratio
to the Exercise Price in effect immediately prior to any such event as the total
number of shares of Common Stock outstanding immediately prior to such event
shall bear to the total number of shares of Common Stock outstanding immediately
after such event.

                                        2
<PAGE>

               4.2. ADJUSTMENT OF NUMBER OF SHARES PURCHASABLE. When any
adjustment is required to be made in the Exercise Price under this Section 4,
(i) the number of shares of Common Stock issuable upon exercise of the Warrants
shall be changed (upward to the nearest full share) to the number of shares
determined by dividing (x) an amount equal to the number of shares issuable
pursuant to the exercise of the Warrants immediately prior to the adjustment
multiplied by the Exercise Price in effect immediately prior to the adjustment,
by (y) the Exercise Price in effect immediately after such adjustment, and (ii)
upon exercise of the Warrant, the holder will be entitled to receive the number
of shares or other securities referred to in Section 4.1 that such holder would
have received had the Warrant been exercised prior to the events referred to in
Section 4.1.

               4.3. ADJUSTMENT FOR REORGANIZATION, CONSOLIDATION, MERGER, ETC.
In case of any reorganization or consolidation of the Corporation with, or any
merger of the Corporation with or into, another entity (other than a
consolidation or merger in which the Corporation is the surviving corporation)
or in case of any sale or transfer to another entity of the majority of assets
of the Corporation, the entity resulting from such reorganization or
consolidation or surviving such merger or to which such sale or transfer shall
be made, as the case may be, shall make suitable provision (which shall be fair
and equitable to the holders of Warrants) and shall assume the obligations of
the Corporation hereunder (by written instrument executed and mailed to each
holder of the Warrants then outstanding) pursuant to which, upon exercise of the
Warrants, at any time after the consummation of such reorganization,
consolidation merger or conveyance, the holder shall be entitled to receive the
shares or other securities or property that such holder would have been entitled
to upon consummation if such holder had exercise the Warrants immediately prior
thereto, all subject to further adjustment as provided in this Section 4.

               4.4. CERTIFICATE AS TO ADJUSTMENTS. In the event of adjustment as
herein provided in paragraphs of this Section 4, the Corporation shall promptly
mail to each Warrant holder a certificate setting forth the Exercise Price and
number of shares of Common Stock issuable upon exercise after such adjustment
and setting forth the kind and amount of share so other securities or property
into which the Warrants shall be exercisable after any adjustment of the
Exercise Price as provided herein.

               4.5. MINIMUM ADJUSTMENT. Notwithstanding the foregoing, no
certificate as to adjustment of the Exercise Price hereunder shall be made if
such adjustment results in a change in the Exercise Price then in effect of less
than two cents ($0.02) and any adjustment of less than two cents ($0.02) of any
Exercise Price shall be carried forward and shall be made at the time of and
together with any subsequent adjustment that, together with the adjustment or
adjustments so carried forward, amounts to two cents ($0.02) or more; provided
however, that upon the exercise of a Warrant, the Corporation shall have made
all necessary adjustments (to the nearest cent) not theretofore made to the
Exercise Price up to and including the date upon which such Warrant is
exercised.

               4.6. NO IMPAIRMENT. The Corporation shall not, by amendment of
its organizational documents or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities, or any other
action, avoid or seek to avoid the

                                        3
<PAGE>

observance or performance of any of the terms of the Warrants, but will at all
times in good faith take any and all action as may be necessary in order to
protect the rights of the holders of the Warrants against impairment. The
Corporation will at all times reserve and keep available out of its authorized
Common Stock, solely for the purpose of issue upon the exercise of this Warrant
as herein provided, such number of shares of Common Stock as shall then be
issuable upon the exercise of this Warrant and other Warrants owned by the
Holder. The Corporation shall from time to time in accordance with applicable
law increase the authorized amount of its Common Stock if at any time the number
of shares of Common Stock remaining unissued and available for issuance shall
not be sufficient to permit exercise of this Warrant and other Warrants owned by
the Holder. The Corporation covenants that all shares of Common Stock which
shall be so issued shall be duly and validly issued and fully paid and
nonassessable and free from all taxes, liens and charges with respect to the
issue thereof, and, without limiting the generality of the foregoing, the
Corporation will take all such action as may be necessary to assure that all
such shares of Common Stock may be so issued without violation of any applicable
law or regulation, or of any requirements of any national securities exchange
upon which the Common Stock of the Corporation may be listed.

               4.7. The issuance of certificates for shares of Common Stock upon
exercise of this Warrant shall be made without deduction to the Holders of this
Warrant for any issuance tax in respect thereof provided that the Corporation
shall not be required to pay any tax which may be payable in respect of any
transfer involved in the issuance and delivery of any certificate in a name
other than that of Holder of this Warrant.

               4.8. The Corporation will at no time close its transfer books
against the transfer of the shares of Common Stock issued or issuable upon the
exercise of this Warrant in any manner which interferes with the timely exercise
of this Warrant

          5. NOTICE OF RECORD DATES.

               5.1. In the event of:

                    (a) Any taking by the Corporation of a record of the Holders
of any class of securities for the purpose of determining the Holders thereof
who are entitled to receive any dividend or other distribution (other than cash

otherwise acquire any shares of stock of any class or any other securities or
property, or to receive any other right;

                    (b) Any capital reorganization of the Corporation, any
reclassification, or recapitalization of the capital stock of the Corporation,

this Warrant specifying (i) the date on which any such record is to be taken for
the purpose of such dividend, distribution or right and stating the amount and

any such reorganization, reclassification, recapitalization, transfer,
consolidation, merger, dissolution, liquidation or winding-up is to take place,
and the time, if any is to be fixed, as of which the Holders of record of Common
Stock will be entitled to exchange their shares of Common Stock for securities
or other property deliverable upon such reorganization, reclassification,

winding-up. Such notice shall be given at least 10 days and not more than 90
days prior to the date therein specified, and such notice shall state that the
action in question or the record date is subject to the effectiveness of a
registration statement under the Securities Act of 1933 or to a favorable vote
of shareholders, if either is required.

          6. REGISTRATION RIGHTS.

               6.1. REGISTRATION OF THE COMMON STOCK. At the request of the
holder, the Corporation agrees to file with the Securities and Exchange
Commission (the "Commission") at the Holder's expense a shelf registration
statement under Rule 415 of the Securities Act or other appropriate registration
statement if a shelf registration is not available under the Securities Act (a
"Registration Statement"), covering the resale of the Warrants and all of the
shares of the Common Stock that may be issued upon exercise of the Warrants
("Warrant Shares") in the event that holders of at least 50,000 Warrants (or
Warrant Shares) request such registration. The holders of Warrants and/or
Warrant Shares may also request "piggyback" registration of their Warrants and
Warrant Shares. Upon any of such requests, the Corporation will:

                    (a) provide written notice (the "Notice") of such request
within 10 days of the receipt of such request to each holder of Warrants and/or
Warrant Shares not a party to the request;

                    (b) use its best efforts to have such Registration Statement
declared effective and to keep it effective for a period of 180 days (the
"Effective Period");

                    (c) give each holder of Warrants and/or Warrant Shares,
their underwriters, if any, and their counsel and accountants a reasonable
opportunity to participate in the preparation of the Registration Statement and
give such persons reasonable access to its books, records, officers and
independent public accountants;

                    (d) furnish to each holder of Warrants and/or Warrant Shares
such numbers of copies of prospectuses, and supplements or amendments thereto,
and such other documents as such holder reasonably requests;

                    (e) register or qualify the securities covered by the
Registration Statement under the securities or blue sky laws of such
jurisdictions within the United States as any holder of Warrants and/or Warrant
Shares shall reasonably request, and do such other reasonable acts and things as
may be required of it to enable such holders to consummate the sale or other
disposition in such jurisdictions of the Warrants and/or Warrant Shares;

                                        5
<PAGE>

                    (f) furnish, at the request of the holders of Warrants
and/or Warrant Shares, on the date Warrant Shares are delivered to the
Underwriters for sale pursuant to such registration, or, if such Warrants and/or
Warrant Shares are not being sold through underwriters, on the date the
Registration Statement with respect to such Warrants and/or Warrant Shares
becomes effective, (A) a securities opinion of counsel representing the
Corporation for the purposes of such registration covering such legal matters as
are customarily included in such opinions and (B) letters of the firm of
independent public accountants that certified the financial statements included
in the Registration Statement, addressed to the underwriters, covering
substantially the same matters as are customarily covered in accountants'
letters delivered to underwriters in underwritten public offerings of securities
and such other financial matters as such holders (or the underwriters, if any)
may reasonably request;

                    (g) otherwise use its best efforts to comply with all
applicable rules and regulations of the Commission;

                    (h) enter into and perform an underwriting agreement with
respect to the sale of the holders' Warrant Shares with the managing
underwriter, if any, selected by the Holder, containing customary (A) terms of
offer and sale of the securities, payment provisions, underwriting discounts and
commissions and (B) representations, warranties, covenants, indemnities, terms
and conditions; and

                    (i) keep the holders of the Warrants and/or Warrant Shares
advised as to the initiation and progress of the registration.

          The Corporation further agrees to supplement or make amendments to
each Registration Statement, if required by the rules, regulations or
instructions applicable to the registration form utilized by the Corporation or
by the Securities Act or rules and regulations thereunder for such Registration
Statement. Notwithstanding the foregoing, if for any reason the effectiveness of
a Registration Statement is delayed or suspended or it ceases to be available
for sales of Warrants and/or Warrant Shares thereunder, the Effective Period
shall be extended by the aggregate number of days of such delay, suspension or
unavailability.

               6.2. LISTING ON SECURITIES EXCHANGE. If the Corporation shall
list or maintain the listing of any shares of Common Stock on any securities
exchange or national market system, it will at its expense and as necessary to
permit the registration and sale of the Warrants and/or Warrant Shares
hereunder, list thereon, maintain and, when necessary, increase such listing to
include such Warrants and/or Warrant Shares.

               6.3. REGISTRATION NOT REQUIRED. Notwithstanding the foregoing,
the Corporation shall not be required to file or maintain the effectiveness of a
registration statement relating to Warrants and/or Warrant Shares after the
first date upon which, in the opinion of counsel to the Holder, all of the
Warrants and/or Warrant Shares covered thereby could be sold by the holders
thereof in any period of three months pursuant to Rule 144 under the Securities
Act, or any successor rule thereto.

               6.4. INDEMNIFICATION.

                                        6
<PAGE>

                    (a) In connection with the Registration Statement, the
Corporation agrees to indemnify holders of Warrants and/or Warrant Shares within
the meaning of Section 15 of the Securities Act, against all losses, claims,
damages, liabilities and expenses (including reasonable costs of investigation)
caused by any untrue, or alleged untrue, statement of a material fact contained
in the Registration Statement, preliminary prospectus or prospectus (as amended
or supplemented if the Corporation shall have furnished any amendments or
supplements thereto) or caused by any omission or alleged omission, to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, except insofar as such losses, claims,
damages, liabilities or expenses are caused by any untrue statement, alleged
untrue statement, omission, or alleged omission based upon information furnished
to the Corporation by the holders of Warrants and/or Warrant Shares expressly
for use therein. The Corporation and each officer, director and controlling
person of the Corporation shall be indemnified by each holder of Warrants and/or
Warrant Shares covered by the Registration Statement for all such losses,
claims, damages, liabilities and expenses (including reasonable costs of
investigation) caused by any such untrue, or alleged untrue, statement or any
such omission, or alleged omission, based upon information furnished to the
Corporation by the holders of Warrants and/or Warrant Shares expressly for use
therein in a writing signed by the holder.

                    (b) Promptly upon receipt by a party indemnified under this
Section 6.4 of notice of the commencement of any action against such indemnified
party in respect of which indemnity or reimbursement may be sought against any
indemnifying party under this Section 6.4, such indemnified party shall notify
the Corporation in writing of the commencement of such action, but the failure
to so notify the Corporation shall not relieve it of any liability that it may
have to any indemnified party otherwise than under this Section 6.4 unless such
failure shall materially adversely affect the defense of such action. In case
notice of commencement of any such action shall be given to the Corporation as
above provided, the Corporation shall be entitled to participate in and, to the
extent it may wish, jointly with any other indemnifying party similarly
notified, to assume the defense of such action at its own expense, with counsel
chosen by it and reasonably satisfactory to such indemnified party. The
indemnified party shall have the right to employ separate counsel in any such
action and participate in the defense thereof, but the fees and expenses of such
counsel (other than reasonable costs of investigation) shall be paid by the
indemnified party unless (i) the Corporation agrees to pay the same, (ii) the
Corporation fails to assume the defense of such action with counsel reasonably
satisfactory to the indemnified party or (iii) the named parties to any such
action (including any impleaded parties) have been advised by such counsel that
representation of such indemnified party and the Corporation by the same counsel
would be inappropriate under applicable standards of professional conduct (in
which case the Corporation shall not have the right to assume the defense of
such action on behalf of such indemnified party). No indemnifying party shall be
liable for any settlement entered into without its consent.

               6.5. CONTRIBUTION.

                    (a) If for any reason the indemnification provisions
contemplated by Section 6.5 are either unavailable or insufficient to hold
harmless an indemnified party in respect

                                        7
<PAGE>

of any losses, claims, damages or liabilities referred to therein, then the
party that would otherwise be required to provide indemnification or the
indemnifying party (in either case, for purposes of this Section 6.5, the
"Indemnifying Party") in respect of such losses, claims, damages or liabilities,
shall contribute to the amount paid or payable by the party that would otherwise
be entitled to indemnification or the indemnified party (in either case, for
purposes of this Section 6.5, the "Indemnified Party") as a result of such
losses, claims, damages, liabilities or expense, in such proportion as is
appropriate to reflect the relative fault of the Indemnifying Party and the
Indemnified Party, as well as any other relevant equitable considerations. The
relative fault of the Indemnifying Party and Indemnified Party shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or omission or alleged omission to state a
material fact related to information supplied by the Indemnifying Party or
Indemnified Party, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The amount paid or payable by a party as a result of the losses, claims,
damages, liabilities and expenses referred to above shall be deemed to include
any legal or other fees or expenses reasonably incurred by such party. In no
event shall any holder of Warrants and/or Warrant Shares covered by the
Registration Statement be required to contribute an amount greater than the
dollar amount of the proceeds received by such holder from the sale of Warrants
and/or Warrant Shares pursuant to the registration giving rise to the liability.

                    (b) The parties hereto agree that it would not be just and
equitable if contribution pursuant to this Section 6.5 were determined by pro
rata allocation (even if the holders or any underwriters or all of them were
treated as one entity for such purpose) or by any other method of allocation
that does not take account of the equitable considerations referred to in the
immediately preceding paragraph. No person or entity determined to have
committed a fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any person or entity
who was not guilty of such fraudulent misrepresentation.

                    (c) The contribution provided for in this Section 6.5 shall
survive the termination or exercise of this Warrant and shall remain in full
force and effect regardless of any investigation made by or on behalf of any
Indemnified Party.

          7. NO SHAREHOLDER RIGHTS OR LIABILITIES. This Warrant shall not
entitle the Holder hereof to any voting rights or other rights as a shareholder
of the Corporation. No provision hereof, in the absence of affirmative action by
the Holder hereof to purchase shares of Common Stock, and no mere enumeration
hereon of the rights or privileges of the Holder hereof shall give rise to any
liability of such Holder for the Warrant Price or as a shareholder of the
Corporation, whether such liability is asserted by the Corporation or by
creditors of the Corporation.

          8. REPRESENTATIONS OF HOLDER. The Holder hereby represents and
acknowledges to the Corporation that:

                                        8

               8.1. This Warrant, the Common Stock issuable upon exercise of
this Warrant, and any securities issued with respect to either of them by way of
a stock dividend or stock split or in connection with a recapitalization,
merger, consolidation or other reorganization will be "restricted securities" as
such term is used in the rules and regulations under the Securities Act and that
such securities have not been and will not be registered under the Securities
Act or any state securities law, and that such securities must be held
indefinitely unless registration is effected or transfer can be made pursuant to

of this Warrant or the Common Stock of the Corporation issuable upon exercise of
this Warrant, and it has no intention of selling such securities in a public
distribution in violation of the federal securities laws or any applicable state
securities laws; provided that nothing contained herein will prevent Holder from
transferring such securities in compliance with the terms of this Warrant and
the applicable federal and state securities laws;

               8.5. He is an "accredited investor" within the meaning of
paragraph (a) of Rule 501 of Regulation D promulgated by the Securities and

and business information through disclosure meetings or otherwise, and has had

it will not exercise the Warrant unless the same is true with respect to its
decision to exercise;

               8.7. He has the knowledge and experience in financial and
business matters to be capable of evaluating the merits and risks of this
investment and to protect its own interest;

               8.8. He acknowledges that an investment in the Corporation and
this Warrant involves a high degree of risk; and

               8.9. This Warrant, or any substitution warrant, issued to Holder
(or his assigns) is subject to the following legend condition:

          "THE TRANSFER OF THIS WARRANT IS SUBJECT TO RESTRICTIONS CONTAINED
          HEREIN. THIS WARRANT HAS BEEN ISSUED IN RELIANCE UPON THE
          REPRESENTATION OF THE HOLDER THAT IT HAS BEEN ACQUIRED FOR INVESTMENT
          PURPOSES AND NOT WITH A VIEW TOWARDS THE RESALE OR OTHER DISTRIBUTION
          THEREOF. NEITHER THIS WARRANT


                                        9
<PAGE>

          NOR THE SHARES ISSUABLE UPON THE EXERCISE OF THIS WARRANT HAVE BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933."

               8.10. The Corporation may affix the following legend (in addition
to any other legend(s), if any, required by applicable state corporate and/or
securities laws) to certificates for shares of Common Stock (or other
securities) issued upon exercise of this Warrant ("Warrant Shares"):

          "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933 AS AMENDED OR ANY STATE
          SECURITIES LAW, AND MAY NOT BE SOLD, TRANSFERRED OR ASSIGNED IN THE
          ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT OR AN OPINION OF THE
          COMPANY'S COUNSEL THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT"

          9. NOTICE OF PROPOSED TRANSFERS. The Holder of this Warrant, by
acceptance hereof, agrees to comply in all respects with the provisions of this
agreement. Prior to any proposed transfer of this Warrant or any Warrant Shares,
unless there is in effect a registration statement under the Securities Act of
1933, as amended (the "Securities Act") covering the proposed transfer, the
Holder of such securities shall give written notice to the Corporation of such
Holder's intention to effect such transfer. Each such notice shall describe the
manner and circumstances of the proposed transfer in sufficient detail, and
shall be accompanied (except in transactions in compliance with Rule 144) by
either (1) a written opinion of legal counsel who shall be reasonably
satisfactory to the Corporation addressed to the Corporation and reasonably
satisfactory in form and substance to the Corporation's counsel, to the effect
that the proposal transfer of the Warrant and/or Warrant Shares may be effected
without registration under the Securities Act, or (ii) a "no action" letter from
the U.S. Securities and Exchange Commission (the "Commission") to the effect
that the transfer of such securities without registration will not result in a
recommendation by the staff of the Commission that enforcement action be taken
with respect thereto, whereupon the Holder of such securities shall be entitled
to transfer such securities in accordance with the terms of the notice delivered
by the Holder to the Corporation. Each new certificate evidencing the Warrant
and/or Warrant Shares so transferred shall bear the appropriate restrictive
legends set forth herein, except that such certificate shall not bear such
restrictive legend if, in the opinion of counsel for the Corporation, such
legend is not required in order to establish or assist in compliance with any
provisions of the Securities Act or any applicable state securities laws.

          10. LOST, STOLEN, MUTILATED OR DESTROYED WARRANT. If this Warrant is
lost, stolen, mutilated or destroyed, the Corporation may, on such terms as to
indemnity or otherwise as it may in its discretion reasonably impose (which
shall, in the case of a mutilated Warrant, include the surrender thereof), issue
a new Warrant of like denomination and tenor as the Warrant so lost, stolen,
mutilated or destroyed. Any such new Warrant shall constitute an original
contractual obligation of the Corporation, whether or not the allegedly lost,
stolen, mutilated or destroyed. The Warrant shall be at any time enforceable by

of this Warrant, the Corporation may deem and treat the Holder as the absolute

provisions of this Section 9 for the giving of notice.

          13. GOVERNING LAW. The validity, interpretation and performance of
this Warrant shall be governed by the laws of the Commonwealth of Virginia
without regard to principles of conflicts of laws.

          14. SUCCESSORS, ASSIGNS. Subject to the restrictions on transfer by

for any reason be declared invalid, such decision shall not affect the validity
of any remaining portion, which remaining portion shall remain in force and
effect as if this Warrant had been executed with the invalid portion thereof
eliminated, and it is hereby declared the intention of the parties hereto that
they would have executed the remaining portion of this Warrant without including
therein any such part which may, for any reason, be hereafter declared invalid,

          16. GENDER AND NUMBER. In this Warrant, the masculine, feminine and

WHEREAS, SpaceDev can provide the below defined Statement of Work and University
is desirous of said Statement of Work; and,

WHEREAS it is has been approved by the Federal Sponsoring Agency, National
Aeronautics and Space Administration (NASA), and deemed in the best interest of
the University;

NOW, THEREFORE, the parties, in consideration of the following mutual covenants
and undertakings and other good and valuable consideration, hereby agree as
follows:


BACKGROUND
- ----------

The Cosmic Hot Interstellar Plasma Spectrometer (CHIPS) is a NASA sponsored
University-class Explorer space flight mission. CHIPS will map the sky in 50
degree x 26 degree "resels" in the scientifically critical but virtually
unexplored extreme ultraviolet (EUV) band between 90 and 260 angstrom. The CHIPS
spectrograph will be carried aboard a dedicated mini-satellite (CHIPSat) to be
developed by SpaceDev, Inc. and launched as a secondary payload aboard a
Delta-II booster with a Global Positioning Satellite primary payload. Although
this configuration differs from the flight implementation envisioned in the
original proposal, the scientific goals are unchanged and the data products are
improved.

The University of California Berkeley Space Sciences Laboratory has received
NASA Research Grant Number NAG5-5213 to perform the CHIPS mission. The
University's Principal Investigator for CHIPS is Dr. Mark V. Hurwitz.

The University's largest subcontractor (First Tier) under this grant is
SpaceDev, Incorporated (SpaceDev). SpaceDev shall be responsible for
manufacturing and supplying the spacecraft bus for the CHIPS scientific payload.
During the concept study period, a NASA review committee reviewed and approved
SpaceDev as the spacecraft provider to CHIPS.

                                        1

B/C/D/E periods of the CHIPS mission. Under this agreement, and as defined in
this SOW, SpaceDev is required to provide the specified spacecraft bus along
with associated services and defined deliverables to the University in support
of NASA Research Grant NAG5-5213 entitled: COSMIC HOT INTERSTELLAR PLASMA
SPECTROMETER (CHIPS).

1.1    SCOPE OF WORK

The scope of the work encompasses all effort required by SpaceDev to design,

ARTICLE I - The materials, supplies or services covered by this order shall be
furnished by Seller subject to all the terms and conditions set forth in this
order including the following, which Seller, in accepting this order, agrees to
be bound by and to comply with in all particulars and no other terms or
conditions shall be binding upon the parties unless hereafter accepted by them
in writing. Written acceptance or shipment of all or any portion of the
materials or supplies, or the performance of all or any portion of the services,
covered by this order shall constitute unqualified acceptance of all its terms
and conditions. The terms of any proposal referenced to in this order are
included and made a part of the order only in the extent it specifies the
materials, supplies, or services ordered, the price therefor, and the delivery
thereof, and then only to the extent that such terms are consistent with the
terms and conditions of this order.

ARTICLE 2 - INSPECTION. The services, materials and supplies furnished shall be
exactly as specified in this order free from all defects in Seller's
performance, design, workmanship and materials, and, except as otherwise
provided in this order, shall be subject to inspection and test by University at
all times and places. If, prior to final acceptance, any services and any
materials and supplies furnished therewith are found to be incomplete, or not as
specified, University may reject them, require Seller to correct them without
charge, or require delivery of such materials, supplies, or services at a
reduction in price which is equitable under the circumstances. If Seller is
unable or refuses to correct such items within a time deemed reasonable by
University, University may terminate the order in whole or in part, Seller shall
bear all risks as to rejected services and, in addition to any costs for which
Seller may become liable to University under other provisions of this order,
shall reimburse University for all transportation costs, other related costs
incurred, or payments to Seller in accordance with the terms of this order for
unaccepted services and materials and supplies incidental thereto.
Notwithstanding final acceptance and payment, Seller shall be liable for latent
defects, fraud or such gross mistakes as amount to fraud.

ARTICLE 3 - CHANGES. University may make changes within the general scope of
this order in drawings and specifications for specially manufactured supplies,
place of delivery, method of shipment or packing of the order by giving notice
to Seller and subsequently confirming such changes in writing. If such changes
affect the cost of or the time required for performance of this order, an
equitable adjustment in the price or delivery or both shall be made. No change
by Seller shall be allowed without written approval of University. Any claim of
Seller for an adjustment under this Article must be made in writing within
thirty (30) days from the date of receipt by Seller of notification of such
change unless University waives this condition in writing. Nothing in this
Article shall excuse Seller from proceeding with performance of the order as
changed hereunder.

ARTICLE 4 - TERMINATION
A. University may, by written notice stating the extent and effective date,
cancel and/or terminate this order for convenience in whole or in part, at any
time. University shall pay Seller as full compensation for performance until
such termination:
(1) the unit or pro rata order price for the performed and accepted portion; and
(2) a reasonable amount, not otherwise recoverable from other sources by Seller
as approved by University, with respect to the unperformed or unaccepted portion
of this order, provided compensation hereunder shall in no event exceed the
total order price.
B. University may by written notice terminate this order for Seller's default,
in whole or in part, at any time, if Seller refuses or fails to comply with the
provisions of this order, or so fails to make progress as to endanger
performance and does not cure such failure within a reasonable period of time,
or fails to perform the services within the time specified or any written
extension thereof. In such event, University may purchase or otherwise secure
services and, except as otherwise provided herein, Seller shall be liable to
University for any excess costs occasioned University thereby. If, after notice
of termination for default, University determines that the Seller was not in
default or that the failure to perform this order was due to causes beyond the
control and without the fault or negligence of Seller (including, but not
restricted to, acts of God or of the public enemy, acts of University, acts of
Government, fires, floods, epidemics, quarantine restrictions, strikes, freight
embargoes, unusually severe weather, and delays of a subcontractor or supplier
due to such causes and without the fault or negligence of the subcontractor or
supplier), termination shall be deemed for the convenience of University, unless
University shall determine that the services covered by this order were
obtainable by Seller from other sources in sufficient time to meet the required
performance schedule.
C. If University determines that Seller has been delayed in the work due to
causes beyond the control and without the fault or negligence of Seller,
University may extend the time for completion, of the work called for by this
order, when promptly applied for in writing by Seller; any extension granted
shall be effective only if given in writing. If such delay is due to failure of
University, not caused or contributed to by Seller, to perform services or
deliver property in accordance with the terms of the order, the time and price
of the order shall be subject to change under the Changes Article. Sole remedy
of Seller in event of delay by failure of University to perform shall, however,
be limited to any money actually and necessarily expended in the work during the
period of delay, solely by reason of the delay. No allowance will be made for
anticipated profits.
D. The rights and remedies of University provided in this Article shall not be

out of this order, or receipts in full in lieu thereof as University may
require, and if required in either case, an affidavit that as far as it has

University all monies that the latter may be compelled to pay in discharging
such lien or claim, including all costs and reasonable attorneys' fees.

skilled in the work assigned to him or her, and shall devote only its

assigned to work under this order.

                                                       STOCK OPTION PLAN OF 1999


         1.       PURPOSE OF THE PLAN.
                  --------------------

                  a. Under the Stock Option Plan of 1999 (the "Plan") of
                  SpaceDev Inc. (the "Company"), Incentive Stock Options,
                  Supplemental Stock Options, and Stock Bonuses may be granted
                  to eligible persons to purchase shares of the Company's common
                  stock. The Plan is designed to enable the Company to attract,
                  retain and motivate its directors, officers, employees, and
                  Affiliates (as defined below) by providing for or increasing
                  the proprietary interest in the Company.

                  b. The word "Affiliate" as used in the Plan means any parent
                  corporation or subsidiary corporation of the Company, as those
                  terms are defined in Sections 424(e) and (f), respectively, of
                  the Internal Revenue Code of 1986, as amended ("the Code").

                  c. The Company intends that the rights issued under the Plan
                  ("Stock Awards") shall, in the discretion of the Board of
                  Directors of the Company (the "Board") or any committee to
                  which responsibility for administration of the Plan has been
                  delegated pursuant to subparagraph 2.c., be either (i) stock
                  options granted pursuant to paragraph 5 hereof, including
                  incentive stock options as that term is used in Section 422 of
                  the Code ("Incentive Stock Options"), or options which do not
                  qualify as Incentive Stock Options ("Supplemental Stock
                  Options") (together hereinafter referred to as "Options"), or
                  (ii) stock bonuses or rights to purchase restricted stock
                  granted pursuant to paragraph 6 hereof. All Options shall be
                  separately designated Incentive Stock Options or Supplemental
                  Stock Options at the time of grant, and in such form as issued
                  pursuant to paragraph 5, and a separate certificate or
                  certificates shall be issued for shares purchased on exercise
                  of each type of Option. An Option designated as a Supplemental
                  Stock Option shall not be treated as an Incentive Stock
                  Option.

         2.       ADMINISTRATION.
                  ---------------

                  a. The Plan shall be administered by the Board unless and
                  until the Board delegates administration to a committee, as
                  provided in subparagraph 2.c.

                  b. The Board shall have the power, subject to, and within the
                  limitations of, the express provisions of the Plan:

                           Stock Awards; when and how Stock Awards shall be
                           granted; whether a Stock Award will be an Incentive
                           Stock Option, a Supplemental Stock Option, a stock
                           bonus, a right to purchase restricted stock, or a
                           combination of the foregoing; the provisions of each
                           Stock Award granted (which need not be identical),
                           including the time or times when a person shall be
                           permitted to purchase or receive stock pursuant to a
                           Stock Award; and the number of shares with respect to
                           which Stock Awards shall be granted to each such
                           person.

                           (ii) To construe and interpret the Plan and Stock
                           Awards granted under it, and to establish, amend, and
                           revoke rules and regulations for its administration.
                           The Board, in the exercise of this power, may correct
                           any defect, omission, or inconsistency in the Plan or
                           in any Stock Award, in a manner and to the extent it
                           shall deem necessary or expedient to make the Plan
                           fully effective.

                           (iii) To amend the Plan as provided in paragraph 15.

                           (iv) Generally, to exercise such powers and to
                           perform such acts as the Board deems necessary or
                           expedient to promote the best interests of the
                           Company.

                  c. The Board may delegate administration of the Plan to a
                  committee composed of not fewer than two (2) members (the
                  "Committee"), both of the members of which Committee shall be
                  disinterested persons, if required and as defined by the
                  provisions of subparagraph 2.d. If administration is delegated
                  to a Committee, the Committee shall have, in connection with
                  the administration of the Plan, the powers theretofore
                  possessed by the Board, subject, however, to such resolutions,
                  not inconsistent with the provisions of the Plan, as may be
                  adopted from time to time by the Board. The Board may abolish
                  the Committee at any time and revest in the Board the
                  administration of the Plan. From time to time, the Board of
                  Directors may increase the size of the Committee and appoint
                  additional members thereof, remove members (with or without
                  cause) and appoint new member in substitution therefor, or
                  fill vacancies however caused.

                  d. The term "disinterested person," as used in the Plan, shall
                  mean a director: (i) who was not during the one (1) year prior
                  to service as an administrator of the Plan granted or awarded
                  equity securities pursuant to the Plan or any other plan of
                  the Company or any of its affiliates entitling the
                  participants therein to acquire equity securities of the
                  Company or any of its affiliates; or (ii) who is otherwise
                  considered to be a "disinterested person" in accordance with
                  Rule 16b-3 promulgated under the Securities Exchange Act of
                  1934, as amended (the "Exchange Act"), or any other rules,
                  regulations, or interpretations of the Securities and Exchange
                  Commission. Any such person shall otherwise comply with the
                  requirements of Rule 16b-3 promulgated under the Exchange Act.

                  e. Any requirement that an administrator of the Plan be a
                  "disinterested person" shall not apply if the Board or the
                  Committee expressly declares that such requirement shall not
                  apply.

         3.       SHARES SUBJECT TO THE PLAN.
                  ---------------------------

                  a. Subject to the provisions of paragraph 11 relating to
                  adjustments upon changes in stock, the stock that may be
                  issued pursuant to Stock Awards granted under the Plan shall
                  not exceed in the aggregate One Million (1,000,000) shares of
                  the Company's common stock. If any Stock Award granted under
                  the Plan shall for any reason expire or otherwise terminate
                  without having been exercised in full, the stock not purchased
                  under such Stock Award shall again become available for the
                  Plan.

                  b. The stock subject to the Plan may be unissued shares or
                  reacquired shares, bought on the market or otherwise.

                  c. An Incentive Stock Option may be granted to an eligible
                  person under the Plan only if the aggregate fair market value
                  (determined at the time the Option is granted) of the stock
                  with respect to which incentive stock options (as defined in
                  the Code) are exercisable for the first time by such optionee
                  during any calendar year under all Incentive Stock Option
                  plans of the Company and its Affiliates does not exceed One
                  Hundred Thousand Dollars ($100,000). If it is determined that
                  an entire Option or any portion thereof does not qualify for
                  treatment as an Incentive Stock Option by reason of exceeding
                  such maximum, such Option or the applicable portion shall be
                  considered a Supplemental Stock Option.

         4.       ELIGIBILITY.
                  ------------

                  a. Incentive Stock Options may be granted only to full time
                  (minimum 35 hours per week) employees (including officers) of
                  the Company or its Affiliates. A director of the Company shall
                  not be eligible to receive Incentive Stock Options unless such
                  director is also an employee (including an officer) of the
                  Company or any Affiliate. Stock Awards other than Incentive
                  Stock Options may be granted only to employees (including
                  officers) of, directors of, or consultants to the Company or
                  its Affiliates.

                  b. A director shall in no event be eligible for the benefits
                  of the Plan unless at the time discretion is exercised in the
                  selection of the director as a person to whom Stock Awards may
                  be granted, or in the determination of the number of shares
                  which may be covered by Stock Awards granted to the director:
                  (i) the Board has delegated its discretionary authority over
                  the Plan to a Committee which consists solely of
                  "disinterested persons" as defined in subparagraph 2.d. or
                  (ii) the Plan otherwise complies with the requirements of Rule
                  16b-3 promulgated under the Exchange Act, as from time to time
                  in effect. The Board shall otherwise comply with the
                  requirements of Rule 16b-3 promulgated under the Exchange Act,
                  as from time to time in effect. This subparagraph 4.b. shall
                  not apply if the Board or Committee expressly declares that it
                  shall not apply.

<PAGE>

                  c. No person shall be eligible for the grant of an Option
                  under the Plan if, at the time of grant, such person owns (or
                  is deemed to own pursuant to Section 424(d) of the Code) stock
                  possessing more than ten percent (10%) of the total combined
                  voting power of all classes of stock of the Company or of any
                  of its Affiliates unless the exercise price of such Option is
                  at least one hundred ten percent (110%) of the fair market
                  value of such stock at the date of grant and the term of the
                  Option does not exceed five (5) years from the date of grant.

         5.       OPTION PROVISIONS
                  -----------------

                  Each Option shall be in such form and shall contain such terms
         and conditions the Board or the Committee shall deem appropriate. The
         provisions of separate Options need not be identical, but each Option
         shall include (through incorporation of provisions hereof by reference
         in the Option or otherwise) the substance of each of the following
         provisions:

                  a. No Option shall be exercisable after the expiration of ten
                  (10) years from the date it was granted.

                  b. The exercise price of each Incentive Stock Option shall be
                  not less than one hundred percent (100%) of the fair market
                  value of the stock subject to the Option on the date the
                  Option is granted. The exercise price of each Supplemental
                  Stock Option shall be not less than eighty-five (85%) of the
                  fair market value of the stock subject to the Option on the
                  date the Option is granted.

                  c. The purchase price of stock acquired pursuant to an Option
                  shall be paid, to the extent permitted by applicable statutes
                  and regulations, either (i) in cash at the time the Option is
                  exercised, or (ii) at the discretion of the Board or the
                  Committee, either at the time of the grant or exercise of the
                  Option, (A) by delivery to the Company of other common stock
                  of the Company, (B) according to a deferred payment or other
                  arrangement (which may include, without limiting the
                  generality of the foregoing, the use of other common stock of
                  the Company) with the person to whom the Option is granted or
                  to whom the Option is transferred pursuant to subparagraph
                  5(d), or (C) in any other form of legal consideration that may
                  be acceptable to the Board or the Committee.

                  In the case of any deferred payment arrangement, interest
                  shall be payable at least annually and shall be charged at
                  the minimum rate of interest necessary to avoid the
                  treatment as interest, under any applicable provisions of
                  the Code, of any amounts other than amounts stated to be
                  interest under the deferred payment arrangement.

                  d. An Option shall not be transferable except by will or by
                  the laws of descent and distribution, and shall be exercisable
                  during the lifetime of the person to whom the Option is
                  granted only by such person.

            TO THE MOON, ASTEROIDS AND MARS, AND BEYOND TO THE STARS

<PAGE>

                  e. The total number of shares of stock subject to an Option
                  may, but need not, be allotted in periodic installments (which
                  may, but need not, be equal). From time to time during each of
                  such installment periods, the Option may become exercisable
                  ("vest") with respect to some or all of the shares allotted to
                  that period, and may be exercised with respect to some or all
                  of the shares allotted to such period and/or any prior period
                  as to which the Option was not fully exercised. During the
                  remainder of the term of the Option (if its term extends
                  beyond the end of the installment periods), the Option may be
                  exercised from time to time with respect to any shares then
                  remaining subject to the Option. The provisions of this
                  subparagraph 5(e) are subject to any Option provisions
                  governing the minimum number of shares as to which an Option
                  may be exercised.

                  f. The Company may require any optionee, or any person to whom
                  an Option is transferred under subparagraph 5(d), as a
                  condition of exercising any such Option, (1) to give written
                  assurances satisfactory to the Company as to the optionee's
                  knowledge and experience in financial and business matters
                  and/or to employ a purchaser representative reasonably
                  satisfactory to the Company who is knowledgeable and
                  experienced in financial and business matters, and that he or
                  she is capable of evaluating, alone or together with the
                  purchaser representative, the merits and risks of exercising
                  the Option; and (2) to give written assurances satisfactory to
                  the Company stating that such person is acquiring the stock
                  subject to the Option for such person's own account and not
                  with any present intention of selling or otherwise
                  distributing the stock. These requirements, and any assurances
                  given pursuant to such requirements, shall be inoperative if
                  (i) the issuance of the shares upon the exercise of the Option
                  has been registered under and then currently effective
                  registration statement under the Securities Act of 1933, as
                  amended (the "Securities Act"), or (ii) as to any particular
                  requirement, a determination is made by counsel for the
                  Company that such requirement need not be met in the
                  circumstances under the then applicable securities laws.

                  g. An Option shall terminate three (3) months after
                  termination of the optionee's employment or relationship as a
                  consultant or director with the Company or an Affiliate,
                  unless (i) such termination is due to such person's permanent
                  and total disability, within the meaning of Section 422(c)(6)
                  of the Code, in which case the Option may, but need not,
                  provide that it may be exercised at any time within one (1)
                  year following such termination of employment or relationship
                  as a consultant or director; or (ii) the optionee dies while
                  in the employ of or while serving as a consultant or director
                  to the Company or an Affiliate, or within not more than three
                  (3) months after termination of such relationship, in which
                  case the Option may, but need not, provide that it may be
                  exercised at any time within eighteen (18) months following
                  the death of the optionee by the person or person to whom the
                  optionee's rights under such Option pass by will or by the
                  laws of descent and distribution; or (iii) the Option by its
                  terms specifies either (a) that it shall termination sooner
                  than three (3) months after termination of the optionee's
                  employment or relationship as a consultant or director or (b)
                  that it may be exercised more than three (3) months after
                  termination of the relationship wit the Company or an
                  Affiliate. This subparagraph 5(g) shall not be construed to
                  extend the term of any Option or to permit anyone to exercise
                  the Option after expiration of its term, nor shall it be
                  construed to increase the number of shares as to which any
                  Option is exercisable form the amount exercisable on the date
                  of termination of the optionee's employment or relationship as
                  a consultant or director.

            TO THE MOON, ASTEROIDS AND MARS, AND BEYOND TO THE STARS

<PAGE>

                  h. The Option may, but need not, include a provision whereby
                  the optionee may elect at any time during the term of his or
                  her employment or relationship as a consultant or director
                  with the Company or any Affiliate to exercise the Option as to
                  any part or all of the shares subject to the Option prior to
                  the stated vesting date of the Option or of any installment or
                  installments specified in the Option. Any shares so purchased
                  from any unvested installment or Option may be subject to a
                  repurchase right in favor of the Company or to any other
                  restriction the Board or the Committee determines to be
                  appropriate.

                  i. In the event an optionee shall cease to be employed by or
                  serve as a consultant or director to the Company or an
                  Affiliate, for any reason or no reason, with our without
                  cause, the Company shall have the right, at any time within
                  180 days after the date the optionee ceases to be an employee
                  of or a consultant or director to the Company, to purchase
                  from the optionee or his personal representative, as the case
                  may be, at the then current fair market value (the "FMV"), as
                  hereinafter defined, up to the number of shares of common
                  stock purchased by optionee upon exercise of any vested
                  Options (the "repurchase Option"); provided, however, that, in
                  the event of termination of the optionee's employment or
                  relationship as a consultant or director to the Company or an
                  Affiliate as described in paragraph 5(g) hereof, the Company
                  shall have the right to exercise the Repurchase Option at any
                  time within 90 days following the expiration of the exercise
                  period as set forth therein. Notwithstanding anything to the
                  contrary, this subparagraph 5(i) shall not apply to Options
                  granted after the closing of the initial public offering
                  pursuant to an effective registration statement under the
                  Securities Act covering the offer and sale of common stock to
                  the public.

                  For the purpose of the foregoing paragraph, the FMV of the
                  common stock shall be deemed to be (i) if traded on a

                  closing price of the security on the date of termination, (ii)
                  if actively traded over-the-counter, the closing ask price on
                  the date of termination, or (iii) if there is no active public
                  market, such price that is reasonably determined by the Board
                  of Directors.

                  (j) To the extent provided by the terms of an Option, the
                  optionee may satisfy any federal, state or local tax

                  otherwise issuable to the participant as a result of the
                  exercise of the Option a number of shares having a fair market
                  value less than or equal to the amount of the withholding tax
                  obligation; or (3) delivering to the Company owned and
                  unencumbered shares of the common stock having a fair market
                  value less than or equal to the amount of the withholding tax

         6.       TERMS OF STOCK BONUSES AND PURCHASES OF RESTRICTED STOCK.
                  ---------------------------------------------------------

                  Each stock bonus or restricted stock purchase agreement shall
         be in such form and shall contain such terms and conditions as the
         Board or the Committee shall deem appropriate. The terms and conditions
         of stock bonus or restricted stock purchase agreements may change from
         time to time, and the terms and conditions of separate agreements need
         not be identical, but each stock bonus or restricted stock purchase
         agreement shall include (through incorporation of provisions hereof by
         reference in the agreement or otherwise) the substance of each of the
         following provisions as appropriate:

                  a. The purchase price under each stock purchase agreement
                  shall be such amount as the Board and Committee shall
                  determine and designate in such agreement. Notwithstanding the
                  foregoing, the Board or the Committee may determine that
                  eligible participants in the Plan may be awarded stock
                  pursuant to a stock bonus agreement in consideration for past
                  services actually rendered to the Company or for its benefit.

                  b. No rights under a stock bonus or restricted stock purchase
                  agreement shall be assignable by any participant under the
                  Plan, either voluntarily or by operation of law, except where
                  such assignment is required by law or expressly authorized by
                  the terms of the applicable stock bonus or restricted stock
                  purchase agreement.

                  c. The purchase price of stock acquired pursuant to a stock
                  purchase agreement shall be paid either: (i) in cash at the
                  time of purchase; (ii) at the discretion of the Board of the
                  Committee, according to a deferred payment or other
                  arrangement with the person to whom the stock is sold; or
                  (iii) in any other form of legal consideration that may be
                  acceptable to the Board or the Committee in their discretion.
                  Notwithstanding the foregoing, the Board or the Committee to
                  which administration of the Plan has been delegated may award
                  stock pursuant to a stock bonus agreement in consideration for
                  past services actually rendered to the Company or for its
                  benefit.

                  d. Shares of stock sold or awarded under the Plan may, but
                  need not, be subject to a repurchase option in favor of the
                  Company in accordance with a vesting schedule to be determined
                  by the Board or the Committee.

                  e. In the event a person ceases to be an employee of or ceases
                  to serve as a consultant to the Company or an Affiliate, the
                  Company may repurchase or otherwise reacquire any or all of
                  the shares of stock held by that person which have not vested
                  as of the date of termination under the terms of the stock
                  bonus or restricted stock purchase agreement between the
                  Company and such person.

         7.       COVENANTS OF THE COMPANY
                  ------------------------

                  a. During the terms of the Stock Awards granted under the
                  Plan, the Company shall keep available at all times the number
                  of shares of stock required to satisfy such Stock Awards.

                  b. The Company shall seek to obtain from each regulatory
                  commission or agency having jurisdiction over the Plan such
                  authority as may be required to issue and sell shares of stock
                  under the Stock Awards granted under the Plan; provided,
                  however, that this undertaking shall not require the Company
                  to register under the Securities Act wither the Plan, any
                  Stock Award granted under the Plan or any stock issued or
                  issuable pursuant to any such Stock Award.

                  If, after reasonable efforts, the Company is unable to obtain
                  from any such regulatory commission or agency the authority
                  which counsel for the Company deems necessary for the lawful
                  issuance and sale of stock under the Plan, the Company shall
                  be relieved from any liability for failure to issue and sell
                  stock upon exercise of such Stock Awards unless and until such
                  authority is obtained.

         8.       USE OF PROCEEDS FROM STOCK.
                  ---------------------------

                  Proceeds from the sale of stock pursuant to Stock Awards under
         the Plan shall constitute general funds for the Company.

         9.       MISCELLANEOUS.
                  --------------

                  a. The Board or the Committee shall have the power to
                  accelerate the time during which a Stock Award may be
                  exercised or the time during which a Stock Award or any part
                  thereof will vest, notwithstanding the provisions in the Stock
                  Award state the time during which it may be exercised or the
                  time during which it will vest.

                  b. Neither an optionee nor any person to whom an Option is
                  transferred under subparagraph 5(d) shall be deemed to be the
                  holder of, or to have any of the rights of a holder with
                  respect to, any shares subject to such Option unless and until
                  such person has satisfied all requirements for exercise of the
                  Option pursuant to its terms.

                  c. Throughout the term of any Option granted pursuant to the
                  Plan, the Company shall make available to the holder of such
                  Option, not later than one hundred twenty (120) days after the
                  close of each of the Company's fiscal years during the Option
                  term, upon request, such financial and other information
                  regarding the Company as comprises the annual report to the
                  stockholders of the Company provided for in the bylaws of the
                  Company.

<PAGE>

                  d. Nothing in the Plan or any instrument executed or Stock
                  Award granted pursuant thereto shall confer upon any eligible
                  employee, consultant, director, or holder of Stock Awards
                  under the Plan any right to continue in the employ of the
                  Company or any Affiliate (or to continue acting as a
                  consultant or director) or shall affect the right of the
                  Company or any Affiliate to terminate the employment or
                  consulting relationship or directorship of any eligible
                  employee, consultant, director or holder of Stock Awards under
                  the Plan with or without cause. In the event that a holder of
                  Stock Awards is permitted or otherwise entitled to take a
                  leave of absence, the Company shall have the unilateral right
                  to (i) determine whether such leave of absence will be treated
                  as a termination of employment or relationship as consultant
                  or director for purposes of paragraphs 5(g) or 6(e) hereof and
                  corresponding provisions of any outstanding Stock Awards, and
                  (ii) suspend or otherwise delay the time or times at which
                  exercisability or vesting would otherwise occur with respect
                  to any outstanding Stock Awards under the Plan.

         10.      CANCELLATION AND RE-GRANT OF OPTIONS.
                  -------------------------------------

                  The Board or the Committee shall have the authority to effect,
         at any time and from time to time, with the consent of the affected
         optionees, (i) the repricing of any or all outstanding Options under
         the Plan and/or (ii) the cancellation of any or all outstanding Options
         under the Plan and the grant in substitution therefor of new Options
         under the Plan covering the same or different number of shares of
         common stock, but having an exercise price per share not less than
         eighty-five percent (85%) of the fair market value (one hundred percent
         (100%) of the fair market value in the case of an Incentive Stock
         Option or, in the case of a 10% stockholder (as defined in subparagraph
         4(c), not less than on hundred and ten percent (110%) of the fair
         market value) per share of common stock on the new grant date.

         11.      ADJUSTMENTS UPON CHANGES IN STOCK.
                  ----------------------------------

                  a. If any change is made in the stock subject to the Plan, or
                  subject to any Stock Award granted under the Plan (through
                  merger, consolidation, reorganization, recaptitalization,
                  stock dividend, dividend in property other than cash, stock
                  split, liquidating dividend, combination of shares, exchange
                  of shares, change incorporate structure or otherwise), the
                  Plan and outstanding Stock Awards will be appropriately
                  adjusted in the class(es) and maximum number of shares subject
                  to the Plan and the class(es) and number of shares and price
                  per share of stock subject to outstanding stock awards.

                  b. In the event of: (1) a dissolution or liquidation of the
                  Company; (2) a merger or consolidation in which the Company is
                  not the surviving corporation; or (3) a reverse merger in
                  which the Company is the surviving corporation but the shares
                  of the Company's common stock outstanding immediately
                  preceding the merger are converted by virtue of the merger
                  into other property, whether in the form of securities, cash
                  or otherwise then to the extent permitted by applicable law:
                  (i) any surviving corporation shall assume any Stock Awards
                  outstanding under the Plan or shall substitute similar Stock
                  Awards for those outstanding under the Plan, or (ii) such
                  Stock Awards shall continue in full force and effect. In the
                  event any surviving corporation refuses to assume or continue
                  such Stock Awards, or to substitute similar Stock Awards for
                  those outstanding under the Plan, then, with respect to Stock
                  Awards held by persons then performing services as employees
                  or as consultants or directors for the Company, as the case
                  may be, the time during which such Stock Awards become vested
                  or may be exercised shall be accelerated and the Stock Awards
                  terminated if not exercised prior to such event.

         12.      RIGHTS IN SHARES BEFORE ISSUANCE AND DELIVERY.
                  ----------------------------------------------

                  No person shall be entitled to the privileges of stock
         ownership unless and until such shares have been issued to such person.

         13.      REQUIREMENTS OF LAW AND OF STOCK EXCHANGES.
                  -------------------------------------------

                  By accepting the Incentive Shares, the Issuee shall represent
         for himself or herself and his or her transferees by will or the laws
         of descent and distribution that, unless a registration statement under
         the Securities Act of 1933 is in effect as to the shares issued under
         this Plan, any and all shares so issued shall be received for his or
         her personal account and not with a view to or for sale in connection
         with any distribution.

                  No certificate or certificates for the Incentive Shares shall
         be issued and delivered prior to the admission of such shares to
         listing on notice of issuance on any stock exchange on which shares of
         that class are then listed, nor unless and until, in the opinion of
         counsel for the Company, such securities may be issued and delivered
         without causing the Company to be in violation of or incur any
         liability under any federal, state or other securities law, any
         requirement of any securities exchange listing agreement to which the
         Company may be a party, or any other requirement of law or of any
         regulatory body having jurisdiction over the Company.

         14.      RESTRICTED SHARES WITH LEGEND.
                  ------------------------------

                  The Company Shares are restricted securities within the
         meaning of the United States federal securities laws. The certificates
         evidencing the Shares received pursuant to this Plan shall bear a
         legend substantially as follows:

         "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
         SECURITIES ACT OF 1933, AS AMENDED (THE "ACT") OR ANY STATE OR
         SECURITIES LAWS AND NEITHER THESE SECURITIES NOR ANY INTEREST THEREIN
         MAY BE OFFERED, SOLD, TRANSFERRED, PLEDGED, HYPOTHECATED OR OTHERWISE
         DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT
         UNDER THE ACT OR SUCH STATE LAWS, OR PURSUANT TO AN EXEMPTION FROM
         REGISTRATION UNDER THE ACT."

         15.      AMENDMENT OF THE PLAN.
                  ----------------------

                  a. The Board at any time, and from time to time, may amend the
                  Plan. However, except as provided in paragraph 11 relating to
                  adjustments upon changes in stock, no amendment shall be
                  effective unless approved by the stockholders of the Company
                  within twelve (12) months before or after the adoption of the
                  amendment, where the amendment will:

                                    approval in order for the Plan to satisfy
                                    the requirements of Section 422(b) of the
                                    Code or to comply with the requirements of

                           (iii)    Modify the Plan in any other way if such
                                    modification requires stockholder approval
                                    in order for the Plan to satisfy the
                                    requirements of Section 422(b) of the Code
                                    or to comply with the requirements of 16b-3

                  b. It is expressly contemplated that the Board may amend the
                  Plan in any respect the Board deems necessary or advisable to
                  provide optionees with the maximum benefits provided or to be
                  provided under the provisions of the Code and the regulations
                  promulgated thereunder relating to employee Incentive Stock
                  Options and/or to bring the Plan and/or Incentive Stock

                  c. Rights and obligations under any Stock Award granted before
                  amendment of the Plan shall not be altered or impaired by any
                  amendment of the Plan unless (i) the Company requests the
                  consent of the person to whom the Stock Award was granted and
                  (ii) such person consents in writing.

                  d. The Board shall have the authority necessary to adopt such
                  modifications, procedures, and subplans as may be necessary or
                  desirable to comply with provisions of the laws of foreign
                  countries in which the company of its Subsidiaries may operate
                  to assure the viability of the benefits from Options granted
                  to Employees employed in such countries and to meet the
                  objectives of the Plan.

                  b. Rights and obligations under any Stock Award granted while
                  the Plan is in effect shall not be altered or impaired by
                  suspension or termination of the Plan, except with the consent
                  of the person to whom the Stock Award was granted.

         17.      EFFECTIVE DATE OF PLAN
                  ----------------------

                  The Plan shall become effective as determined by the Board,

                                  ATTACHMENT I

                         TERMS OF INCENTIVE STOCK OPTION


         The grant hereunder is in connection with and in furtherance of the
Company's compensatory benefit plan for participation of the Company's employees
(including officers) and is intended to comply with the provisions of Rule 701
promulgated by the Securities and Exchange Commission under the Securities Act
of 1933, as amended (the "Act").

         The details of your option are as follows:

1.   The total number of shares of Common Stock subject to this option is set
     forth on the first page of the Incentive Stock Option Agreement. Subject to
     the limitations contained herein, this option shall be exercisable with
     respect to each installment indicated in the Vesting Schedule on the first
     page of the Incentive Stock Option Agreement on or after the date of
     vesting applicable to such installment.

2.       a. The Exercise Price of this option is set forth on the first page of
         the Incentive Stock Option Agreement and is not less than the fair
         market value of the Common Stock on the date of grant of this option.

         b. Payment of the Exercise Price per share is due in full in cash
         (including bank check) upon exercise of all or any part of each
         installment which has become exercisable by you; provided, however,
         that if at the time of exercise the Company's Common Stock is publicly
         traded and quoted regularly in the Wall Street Journal, payment of the
         exercise price, to the extent permitted by applicable statutes and
         regulations, may be made by delivery of already-owned shares of Common
         Stock, or a combination of cash and already-owned Common Stock. Such
         Common Stock (i) shall be valued at its fair market value on the date
         of exercise, (ii) if originally acquired from the Company, must have
         been owned by you for at least six (6) months, and (iii) must be owned
         free and clear of any liens, claims, encumbrances, or security
         interests. Notwithstanding the foregoing, this option may be exercised
         pursuant to a program developed under Regulation T as promulgated by
         the Federal Reserve Board which results in the receipt of cash (or bank
         check) by the Company prior to the issuance of Common Stock.

3.   The minimum number of shares with respect to which this option may be
     exercised at any time is One Thousand (1,000) except (a) as to an
     installment subject to exercise, as set forth in paragraph 1, which amounts
     to fewer than One Thousand (1,000) shares, in which case, as to the
     exercise of that installment, the number of shares in such installment
     shall be the minimum number of shares, and (b) with respect to the final
     exercise of this option, this paragraph 3 shall not apply.

4.   Notwithstanding anything to the contrary contained herein, this option may
     not be exercised unless the shares issuable upon exercise of this option
     are then registered under the Act or, if such shares are not then so
     registered, the Company has determined that such exercise and issuance
     would be exempt from the registration requirements of the Act.

<PAGE>

5.   The term of this option commences on the date hereof and, unless sooner
     terminated as set forth below or in the Plan, terminates on the Expiration
     Date (which date shall be no more than ten (10) years from the date this
     option is granted). This option shall terminate prior to the expiration of
     its terms as follows: three (3) months after the termination of your
     employment with the Company or an affiliate of the Company (as defined in
     the Plan) for any reason or for no reason unless:

                  a. such termination of employment is due to your permanent and
                  total disability (within the meaning of Section 422(c)(6) of
                  the Code), in which event the option shall terminate on the
                  earlier of the termination date set forth above or one (1)
                  year following such termination of employment; or

                  b. such termination is due to your death, in which event the
                  option shall terminate on the earlier of the termination date
                  set forth above or eighteen (18) months after your death; or

                  c. during any part of such three (3) month period the option
                  is not exercisable solely because of the condition set forth
                  in paragraph 4 above, in which event the option shall not
                  terminate until the earlier of the termination date set forth
                  above or until it shall have been exercisable for an aggregate
                  period of three (3) months after the termination of
                  employment; or

                  d. exercise of the option within three (3) months after
                  termination of your employment with the Company or with an
                  affiliate would result in liability under section 16(b) of the
                  Securities and Exchange Act of 1934, in which case the option
                  will terminate on the earlier of the termination date set
                  forth above, the tenth (10th) day after the last date upon
                  which exercise would result in such liability, or six (6)
                  months and ten (10) days after the termination of your
                  employment with the Company or an affiliate.

         However, this option may be exercised following termination of
employment only as to that number of shares as to which it was exercisable on
the date of termination of employment under the provisions of paragraph 1 of
this option.

6. a. This option may be exercised, to the extent specified above, by delivering
a notice of exercise (in a form designated by the Company) together with the
exercise price to the Secretary of the Company, or to such other person as the
Company may designate, during regular business hours, together with such
additional documents as the Company may then require pursuant to subparagraph
5(f) of the Plan.

    b. By exercising this option, you agree that:

                  (i) the Company may require you to enter an arrangement
                  providing for the payment by you to the Company of any tax
                  withholding obligation of the Company arising by reason of the
                  exercise of this option; the lapse of any substantial risk of
                  forfeiture to which the shares are subject at the time of
                  exercise; or the disposition of shares acquired upon such
                  exercise; and
<PAGE>

                  (ii) you will notify the Company in writing within fifteen
                  (15) days after the date of any disposition of any of the
                  shares of the Common Stock issued upon exercise of this option
                  that occurs within two (2) years after the date of this option
                  grant or within one (1) year after such shares of Common Stock
                  are transferred upon exercise of this option.

7.   This option is not transferable, except by will or by the laws of descent
     and distribution, and is exercisable during your life only by you.

8.   This option is not an employment contract, and nothing in this option shall
     be deemed to create in any way whatsoever any obligation on your part to
     continue in the employ of the Company, or of the Company to continue your
     employment with the Company.

9.   Any notices provided for in this option or the Plan shall be given in
     writing and shall be deemed effectively given upon receipt or, in the case
     of notices delivered by the Company to you, five (5) days after deposit in
     the United States mail, postage prepaid, addressed to you at the address
     specified herein or at such other address as you hereafter designate by
     written notice to the Company.

10.  This option is subject to all the provisions of the Plan, a copy of which
     is attached hereto, and its provisions are hereby made a part of this
     provisions, including without limitation the provisions of paragraph 5 of
     the Plan relating to option provisions, and is further subject to all
     interpretations, amendments, rules, and regulations, which may from time to
     time be promulgated and adopted pursuant to the Plan. In the event of any
     conflict between the provisions of this option and those of the Plan, the
     provisions of the Plan shall control.

          This EMPLOYMENT AGREEMENT (the "Agreement") is entered into as of the
24th day of November, 1997, by and between Pegasus Development Group, Inc., a

forth herein, the Company hereby employs Employee,

                                      -1-
<PAGE>

and Employee hereby accepts such employment with the Company, as the President
and Chief Executive Officer of PSDM, and his duties shall be consistent with
such positions.

          2. TERM OF EMPLOYMENT. The term of Employee's employment under this
Agreement shall commence on and as of the date hereof and shall continue
hereafter for a period of 60 months, subject to early termination as provided
for elsewhere in this Agreement. The "term" of this Agreement shall mean and
refer to such 60-month period (or any earlier termination thereof pursuant to
Paragraph 5 hereof).

          3. EXTENT OF SERVICE. During the term hereof, Employee agrees to
devote, during regular business hours, his full time to the performance of his
duties hereunder, it being the intent of the parties hereto that Employee shall
devote his best efforts to furthering, promoting and developing the business and

the Company hereunder, the Company shall pay Employee an aggregate annual salary
for and with respect to each year (annual periods ending with the anniversary
date of the date of this Agreement) during the term hereof as follows:

                                      -2-

justified, may pay to Employee a cash bonus and/or common stock for and with
respect to such year.

             (b) The Company will also provide Employee with a reasonable

hereunder, including travel, lodging and reasonable entertainment expenses,
promptly after presentation to the Company of receipts or other documents
evidencing the incurrence of such expenses.

             (c) The Company hereby grants to Employee options to purchase up to

2,500,000
- ---------------

All options shall expire 60 months from the date of this Agreement.

          5. TERMINATION OF EMPLOYMENT FOR GOOD CAUSE. The Company may terminate
the employment of Employee for "good cause" by giving written notice thereof to
Employee. For the purposes of this Agreement, "good Cause" shall mean only
Employee's (i) drug, alcohol or other substance abuse during regular business
hours or to such extent as to materially affect the performance of his duties
hereunder, (ii) commission of a crime directly related to his employment
hereunder, (iii) conviction of a felony involving moral turpitude, (iv) gross
negligence, gross mismanagement or


                                      -4-
<PAGE>

material willful misconduct in the management of the business and affairs of the
Company or failure to perform such duties as may reasonably be directed by the
Board of Directors and as may be reasonably consistent with the duties and
obligations of Employee's office, or (v) breach of any material provision of
this Agreement. In the event the employment of the Employee is terminated
pursuant to this Paragraph 5, the Company shall have no further liability to
Employee other than for compensation earned but not yet paid. In the event the
company contends that it had good cause to terminate the employment of Employee
pursuant to clause (i), (ii) or (iii) of this Paragraph 5, the Company shall
specify in said written notice the effective date of termination of Employee's
employment, which date may, in the Company's sole discretion, be the date of
such notice. In the event the Company contends that it has good cause to
terminate the employment of Employee pursuant to clause (iv) or (v) of this
Paragraph 5, the Company shall set forth in said written notice reasonable
details of Employee's acts or conduct which the Company alleges constitutes a
willful and gross mismanagement of business and affairs of the Company or a
breach of material provision of this Agreement, as the case may be. The written
notice Shall also specify what, if anything, Employee could do to cure or
eliminate the alleged "good cause" for termination if the matter is susceptible
of cure. If Employee performs the required services or modifies Employee's
performance to correct the matters complained of within sixty (60) days of
receipt of the notice, Employee's breach will be deemed cured. However, if the


                                      -5-
<PAGE>


nature of the matters complained of are such that more than sixty (60) days are
reasonably required to correct the matters complained of, then his breach will
be deemed cured if he commences to correct such matters within the sixty (60)
day period and thereafter diligently prosecutes such correction to completion,
but not to exceed one additional sixty (60) day period. If Employee does not
modify his performance to correct or commence to correct the matter complained
of within the sixty (60) day period or any extension thereof, the Company shall
have the right to terminate this Agreement at the end of such sixty (60) day
period or any extension thereof. It is understood that Employee's performance
hereunder shall not be deemed unsatisfactory solely on the basis of any economic
performance of the Company because such performance will depend in part on a
variety of factors over which Employee has little control.

          6. TERMINATION BY DEATH OR INCAPACITY. The Company may terminate the
employment of Employee by written notice to Employee if, during the term of this
Agreement, Employee shall become incapable of fulfilling his obligations
hereunder because of injury or physical or mental illness which shall exist or
may reasonably be anticipated to exist for a period of six (6) consecutive
months or for an aggregate of six (6) months during any twelve (12) month
period. The death of Employee shall automatically terminate the term of
Employee's employment. In the event the employment of Employee is terminated by
Employee's death or by the Company

                                      -6-
<PAGE>

pursuant to this Paragraph 6 because of injury or physical or mental illness,
the Company shall pay Employee, or Employee's heir(s) (in the event of death),
all compensation of Employee earned but not yet paid up to and through the day
upon which Employee's death occurs or this Agreement is terminated by the
Company due to Employee's incapacity, as applicable, or in accordance with any
written policy applicable to other executives of the Company in effect at the
time of Employee's death or incapacity, if more favorable.

          7. NONCOMPETITION; NONSOLICITATION; CONFIDENTIAL INFORMATION.

             (a) Employee covenants and agrees that, during the term of this
Agreement, he will not, directly or indirectly, whether individually or as an
officer, director, employee or consultant, become employed by, or become a
partner in or a stockholder owning more than one percent (1%) of, any business
which is engaged in the similar business of commercializing outer space and
other related consulting or any other business which is similar to or
competitive with the business now or at any time during the term of this
Agreement being conducted by the Company, including any of its subsidiaries.

             (b) Employee acknowledges that it is the policy of the Company to
maintain as secret and confidential all valuable and

                                      -7-

<PAGE>

unique information heretofore or hereafter acquired, developed or used by the
Company relating to the business, operations, employees, tenants, vendors,
Consultants and/or clients of the Company, which gives the Company a competitive
advantage in its industry, including, without limitation, information about net
costs, profits, markets, suppliers, key personnel, bidding and pricing policies,
operational methods, engineering and technical processes and other business
affairs and methods and other information not readily available to the public
and plans for future developments, operating manuals, financial statements,
forecasts and operating data and business plans (all such information is
hereinafter referred to as "Confidential Information"). Employee recognizes that
the services to be performed by Employee are special and unique, and that by
reason of his duties, he will acquire Confidential Information. Employee
recognizes that all such Confidential Information is the property of the
Company. In consideration of the Company's entering into this Agreement,
Employee agrees that: (i) Employee shall never, directly or indirectly, use,
publish, disseminate or otherwise disclose any Confidential Information obtained
during his employment by the Company (whether obtained prior to, during or after
the term of this Agreement) without the prior written consent of the Company's
Board of Directors; and (ii) during the term of this Agreement, he shall
exercise all due and diligent precautions to protect the integrity of the
Company's vendor, consultant, and customer lists and sources thereof,
statistical data and

                                      -8-
<PAGE>

compilations, agreements, contracts, manuals or other documents embodying any
Confidential Information. Upon termination of Employee's employment by the
Company and at any other time upon request of the Company, he shall return all
such documents (and copies thereof) embodying any Confidential Information in
his possession or control. Employee agrees that the provisions of this
subparagraph (b) are reasonable and necessary to protect the proprietary rights
of the Company in the Confidential Information and its trade secrets, goodwill
and reputation. The provisions of this subparagraph (b) shall not apply to
Confidential information (i) which is known generally to the public, (ii) which
otherwise comes into the public domain without the fault of Employee, (iii)
which Employee obtains from sources other than the Company, or (vi) which the
Company purchases or obtains in connection with any acquisitions of companies or
assets.

             (c) For a period of one year after the termination of this
Agreement for any reason (or for such a lesser period of time as may be
determined by a court of law or equity to be a reasonable limitation on
Employee), Employee shall not solicit, directly or indirectly, any director,
officer or employee of the Company to discontinue that individual's status of
employment with the company, nor to become employed in any activity similar to
or competitive with the business of the company being conducted at the time of
termination of this Agreement within a radius of 2,500 miles of Denver,
Colorado, nor will he solicit or cause or


                                      -9-
<PAGE>


authorize, directly or indirectly to be solicited, for or on behalf of himself
or any third party, from others who are vendors or customers of the Company, any
business which is competitive with the Company within a radius of 2,500 miles of
Denver, Colorado.

             (d) If the covenants contained in this Paragraph 7 are violated, or
threatened to be violated, Employee acknowledges and agrees that such violation
or threatened violation will cause irreparable damage to the Company, that the
remedy at law of the Company will be inadequate and that the Company shall, in
addition to, but not in limitation of, any other rights or remedies available at
law or in equity, be entitled to temporary and permanent injunctive relief
and/or specific performance without the necessity of proving actual damage.

             (e) The parties hereto acknowledge that the provisions of this
Paragraph 7 shall survive the termination of this Agreement.

          8. EMPLOYEE'S RIGHTS AND BENEFITS PERSONAL. Except as may herein
otherwise be specifically provided, the rights, benefits and obligations of
Employee under this agreement are personal to Employee, and no such rights or
benefits shall be subject to voluntary or involuntary alienation, assignment or
transfer.

          11. EFFECT OF HEADINGS. The subject headings of this Agreement are
included for purposes of convenience only, and shall not affect the construction
or interpretation of any of its provisions.

          12. ARBITRATION; ATTORNEYS' FEES. Any controversy or claim arising out
of or to this Agreement, or the breach hereof, shall be resolved by
JAMS/ENDispute in accord with its rules and regulations and judgment on the
award so rendered may be entered in any court having jurisdiction thereof. Any
such proceeding shall be had in Denver, Colorado. If any action or proceeding is
brought to enforce any provisions of this Agreement, the prevailing party shall
be entitled to its costs and expenses in connection therewith, including without
limitation reasonable attorneys' fees.

          13. INJUNCTIVE RELIEF. Employee hereby recognizes, acknowledges and
agrees that in the event of any breach by Employee of any of his covenants,
agreements, duties or obligations hereunder, the Company would suffer great and
irreparable harm,


                                      -12-

<PAGE>

injury and damage, the Company would encounter extreme difficulty in attempting
to prove the actual amount of damages suffered by the Company as a result of
such breach, and the company would not be reasonably or adequately compensated
by an award of damages in any action at law. Employee therefore acknowledges and
agrees that, in addition to any other remedy the Company may have at law, in
equity, by statute or otherwise, in the event of any breach by Employee of any
of his covenants, agreements, duties or obligations hereunder, the Company shall
be entitled to seek and receive temporary, preliminary and permanent injunctive
and other equitable relief from any court of competent jurisdiction to enforce
any of the rights of the Company, or any of the covenants, agreements, duties or
obligations of Employee hereunder, and/or otherwise to prevent the violation of
any of the terms or provisions hereof, all without the necessity of proving the
amount of any actual damage to the Company or any affiliate thereof resulting
therefrom; provided, however, that nothing contained in this Section 13 shall be
deemed or construed in any manner whatsoever as a waiver by the Company of any
of the rights which the Company may have against Employee at law, in equity, by
statute or otherwise arising out of, in connection with or resulting from the
breach by Employee of any of his covenants, agreements, duties or obligations
hereunder.


          14. APPLICABLE LAW. The validity, interpretation and enforcement of
this Agreement shall be governed by the laws of the


                                      -13-
<PAGE>

State of Colorado except that the Federal Arbitration Act shall govern any
arbitration proceeding.

          15. COUNTERPARTS. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which when
taken together shall constitute one and the same Agreement.

          16. SEVERABILITY. If any provision of this Agreement shall be declared
invalid, illegal and/or unenforceable, such provision shall be severed and the
remaining provisions shall continue in full force and effect.

          17. SUCCESSOR AND ASSIGNS. The provisions hereof shall inure to the
benefit of, be binding upon, and be enforceable by the successors and assigns of
the Company.

          18. ASSIGNMENT; SUCCESSORS; AFFILIATES. The Company may assign this
Agreement (or the interest of the Company herein) to any affiliate of the
Company or to any entity which is a party to a merger, reorganization, or
consolidation with the Company or to a subsidiary of the Company or to an entity
or entities acquiring substantially all of the assets of the Company or of any
division with respect to which Employee is providing services (providing any
such assignee assumes the Company's obligation under the Agreement). Employee
shall, if requested by the Company, perform

                                      -14-
<PAGE>

Employee's services and duties, as specified in this Agreement, to or for the
benefit of any affiliate of the Company, including, without limitation, any
parent or subsidiary of the Company or any other subsidiary of any parent of the
Company. Upon such assignment, acquisition, merger, consolidation, or
reorganization, the term "Company" as used herein shall be deemed to refer to
such assignee or such successor entity. Employee shall not have the right to
assign Employee's interest in this Agreement, any rights under this Agreement or
any duties imposed under this Agreement nor shall Employee (or Employee's
spouse, heirs, beneficiaries, administrators or executors) have the right to
pledge, hypothecate or otherwise encumber Employee's right to receive
compensation hereunder without the consent of the Company.

          19. FURTHER ASSURANCES. The Company and Employee each agree to execute
and deliver any and all additional instruments and to perform any and all
additional acts deemed by either party to be


                                      -15-

necessary or proper to carry into effect the terms, conditions and provisions of

                              EMPLOYMENT AGREEMENT
                              --------------------

         This EMPLOYMENT AGREEMENT (the "Agreement") is entered into as of the
7th day of February, 1998, by and between Integrated Space Systems, Inc., a
California corporation (the "Company"), and Thomas W. Brown ("Employee").

                                 RECITALS

         A. The Company is principally engaged in the business of providing
engineering analysis, design, test support and field engineering for
aerospace-related projects.
         B. Effective this date, SpaceDev, Inc., a Colorado corporation ("SPDV")
has acquired all of the issued and outstanding capital stock of the Company (the
"Acquisition"). In connection with and as a material condition to completion of
the Acquisition, certain shareholders and management employees of the Company,
including Employee, have agreed to enter into employment agreements with the
Company.
         C. The Company desires to retain Employee as Chief Financial Officer of
the Company, and Employee desires to accept such employment on the terms and
conditions set forth herein.
         NOW, THEREFORE, based upon the following covenants, conditions and
promises the parties hereto do hereby agree as follows:

                                      -1-
<PAGE>

         1. EMPLOYMENT AND DUTIES. Subject to the terms and conditions set forth
herein, the Company hereby employs Employee, and Employee hereby accepts such
employment with the Company, as the Chief Financial Officer of the Company, and
his duties shall be consistent with such positions.
         2. TERM OF EMPLOYMENT. The term of Employee's employment under this
Agreement shall commence on and as of the date hereof and shall continue
hereafter for a period of 36 months, subject to early termination as provided
for elsewhere in this Agreement. The "term" of this Agreement shall mean and
refer to such 36-month period (or any earlier termination thereof pursuant to
Section 5 hereof).
         3. EXTENT OF SERVICE. During the term hereof, Employee agrees to and
shall devote his full time to the performance of his duties hereunder, it being
the intent of the parties hereto that Employee shall devote his best efforts to
furthering, promoting and developing the business, activities and interests of
the Company. Employee acknowledges that the "interests of the Company" include
the business, activities and interests of SPDV, its subsidiaries and affiliates,
and as a result, Employee may also be requested by the Chief Executive Officer
or Board of Directors of the Company to undertake various management
responsibilities on a full- or part-time basis for or on behalf of SPDV for all
or part of the term.
         4. COMPENSATION. As compensation for the services which Employee is to
render hereunder, the Company shall pay Employee the following aggregate annual
salary for and with respect to each year (annual periods ending with the
anniversary date of the date of this Agreement) during the term hereof: $60,000
for the first year, $80,000 for the second year and $100,000 for the third year.

                                      -2-
<PAGE>

Employee's salary during each of such years shall be paid in accordance with the
normal payroll practices of the Company. At the end of each year during the term
hereof, the Board of Directors of the Company may review the compensation of
Employee hereunder and if it, in its sole discretion, believes it to be
justified, may pay to Employee a cash bonus for and with respect to such year.
                  (a) The Company will provide Employee with such fringe
benefits as are within the Company's policy as approved by the Board of
Directors of the Company. The Company shall also reimburse Employee for expenses
reasonably incurred by him in carrying out his duties hereunder, including
travel, lodging and reasonable entertainment expenses, promptly after
presentation to the Company of receipts or other documents evidencing the
incurrence of such expenses providing that such expenses have been approved in
advance by the Chief Executive Officer of the Company or are otherwise
consistent with policy on such matters as established by the Company's Board of
Directors.
                  (b) The Company shall cause SPDV to grant to Employee options
to purchase shares of common stock of SPDV in the amounts and upon the terms set
forth in Exhibit A attached hereto and incorporated herein by this reference.

         5. TERMINATION OF EMPLOYMENT FOR GOOD CAUSE. The Company may terminate
the employment of Employee for "good cause" by giving written notice thereof to
Employee. For the purposes of this Agreement, "good cause" shall mean only
Employee's (i) drug, alcohol or other substance abuse during regular business

                                      -3-
<PAGE>

hours or to such extent as to materially affect the performance of his duties
hereunder, (ii) commission of a crime directly related to his employment
hereunder, (iii) conviction of a felony involving moral turpitude, (iv)
negligence, gross mismanagement or willful misconduct in the management of the
business and affairs of the Company or failure to perform such duties as may
reasonably be directed by the Board of Directors and as may be reasonably
consistent with the duties and obligations of Employee's office, or (v) breach
of any material provision of this Agreement. In the event the employment of the
Employee is terminated pursuant to this Section 5, the Company shall have no
further liability to Employee other than for compensation earned but not yet
paid. In the event the Company contends that it had good cause to terminate the
employment of Employee pursuant to clause (i), (ii) or (iii) of this Section 5,
the Company shall specify in said written notice the effective date of
termination of Employee's employment, which date may, in the Company's sole
discretion, be the date of such notice. In the event the Company contends that
it has good cause to terminate the employment of Employee pursuant to clause
(iv) or (v) of this Section 5, the Company shall set forth in said written
notice reasonable details of Employee's acts or conduct which the Company
alleges constitutes a willful and gross mismanagement of business and affairs of
the Company or a breach of material provision of this Agreement, as the case may
be. The written notice shall also specify what, if anything, Employee could do
to cure or eliminate the alleged "good cause" for termination if the matter is
susceptible of cure. If Employee performs the required services or modifies
Employee's performance to correct the matters complained of within sixty (60)
days of receipt of the notice, Employee's breach will be deemed cured. However,

                                      -4-
<PAGE>

if the nature of the matters complained of are such that more than sixty (60)
days are reasonably required to correct the matters complained of, then his
breach will be deemed cured if he commences to correct such matters within the
sixty (60) day period and thereafter diligently prosecutes such correction to
completion, but not to exceed one additional sixty (60) day period. If Employee
does not modify his performance to correct or commence to correct the matter
complained of within the sixty (60) day period or any extension thereof, the
Company shall have the right to terminate this Agreement at the end of such (60)
day period or any extension thereof. It is understood that Employee's
performance hereunder shall not be deemed unsatisfactory solely on the basis of
any economic performance of the Company because such performance will depend in
part on a variety of factors over which Employee has little control.
         6. TERMINATION BY DEATH OR INCAPACITY. The Company may terminate the
employment of Employee by written notice to Employee if, during the term of this
Agreement, Employee shall become incapable of fulfilling his obligations
hereunder because of injury or physical or mental illness which shall exist or
may reasonably be anticipated to exist for a period of six (6) consecutive
months or for an aggregate of six (6) months during the term hereof. The death
of Employee shall automatically terminate the term of Employee's employment. In
the event the employment of Employee is terminated by Employee's death or by the
Company pursuant to this Section 6 because of injury or physical or mental
illness, the Company shall pay Employee, or Employee's heir(s) (in the event of
death), all compensation of Employee earned but not yet paid up to and through
the day upon which Employee's death occurs or this Agreement is terminated by

                                      -5-
<PAGE>

the Company due to Employee's incapacity, as applicable, or in accordance with
any written policy applicable to other executives of the Company in effect at
the time of Employee's death or incapacity, if more favorable.
         7. TERMINATION WITHOUT CAUSE. The Company may terminate the employment
of Employee without cause at any time in which event Employee and the Company
agree that the sole amounts due and owing to Employee hereunder (whether as
"severance pay" or otherwise) shall be $100,000, $70,000 or $60,000 for a
termination of employment without cause during year one, year two or year three
of the term, respectively.
         8. NONCOMPETITION; NONSOLICITATION; CONFIDENTIAL INFORMATION.
         (a) Employee covenants and agrees that, during the term he will not,
directly or indirectly, whether individually or as an officer, director,
employee or consultant, become employed by, or become a partner in or a
stockholder owning more than one percent (1%) of, any business which is engaged
in the business of providing aerospace engineering services and other related
consulting or any other business which is similar to or competitive with the
business now or at any time during the term of this agreement being conducted by
SPDV and/or the Company.

         (b) Employee acknowledges that it is the policy of the Company (for
purposes of this subsection 8 (b) the term ACompany@ shall also, refer to SPDV,
any subsidiary, parent or other affiliate of the Company or of SPDV) to maintain
as secret and confidential all valuable and unique information heretofore or
hereafter acquired, developed or used by the Company relating to the business,
operations, employees and/or clients of the Company, including SPDV, which gives

                                      -6-
<PAGE>

the Company a competitive advantage in its industry, including, without
limitation: information about net costs, profits, markets, suppliers,
technology, key personnel and consultants, pricing policies, operational
methods, designs, technical and systems processes, relationships with
universities, the National Aeronautics and Space Administration and other
governmental agencies, and other business affairs and methods and other
information not readily available to the public, plans for future developments,
operating manuals, financial statements, forecasts and operating data and
business plans (all such information is hereinafter referred to as "Confidential
Information"). Employee recognizes and acknowledges that the services heretofore
performed by Employee and those to be performed by Employee are special and
unique, and that by reason of his duties, he has acquired and will acquire
Confidential Information. Employee recognizes that all such Confidential
Information is the property of the Company. In consideration of the Company's
entering into this Agreement, Employee agrees that: (i) Employee shall never,
directly or indirectly, use, publish, disseminate or otherwise disclose any
Confidential Information obtained during his employment by the Company (whether
obtained prior to, during or after the term of this Agreement) without the prior
written consent of the Company's Board of Directors; and (ii) during the term of
this Agreement, he shall exercise all due and diligent precautions to protect
the integrity of the Company's designs, processes, systems, know-how,
statistical data and compilations, agreements, contracts, manuals or other
documents embodying any Confidential Information. Upon termination of Employee's

                                      -7-
<PAGE>

employment by the Company and at any other time upon request of the Company, he
shall return all such documents (and copies thereof) embodying any Confidential
Information in his possession or control. Employee agrees that the provisions of
this subparagraph (b) are reasonable and necessary to protect the proprietary
rights of the Company in the Confidential Information and its trade secrets,
goodwill and reputation. The provisions of this subparagraph (b) shall not apply
to Confidential Information (i) which is known generally to the public, (ii)
which otherwise comes into the public domain without the fault of Employee, or
(iii) which Employee obtains from sources other than the Company.
         (c) For a period of 36 months after the termination of this Agreement
for any reason other than a termination by the Company under Section 7 (or for
such a lesser period of time as may be determined by a court of law or equity to
be a reasonable limitation on Employee), Employee shall not: (i) solicit,
directly or indirectly, any director, officer or employee of the Company to
discontinue that individual's status of employment with the Company; (ii) become
employed in any activity similar to or competitive with the business of the
Company or of SPDV being conducted at the time of termination of this Agreement
anywhere in the world; or (iii) solicit or cause or authorize, directly or
indirectly to be solicited, for or on behalf of himself or any third party, from
customers, clients, consultants or other providers of goods and services (all of
whom are collectively referred to as "Company Clients") of the Company or of
SPDV, any business which is competitive with the Company or with SPDV anywhere
in the world. "Clients" shall also include persons whom or entities which the
Company has identified and targeted (at or prior to the date of termination of
this Agreement) as intended customers or clients of SPDV:

                                      -8-
<PAGE>

         (d) In the event of a termination by the Company under Section 7 of
this agreement clauses (ii) and (iii) of subsection 8 (c) above shall be
adjusted as follows:
                  (1) Employee shall not, for a period of 18 months following
such termination: (i) become an officer or director, or maintain an ownership
interest of more than one percent in any company that is directly competitive
with the business of SPDV; or (ii) be employed by or consult to any business
which is directly competitive with SPDV anywhere in the world. Nothing set forth
herein shall prevent Employee following termination of this Agreement from
securing any engineering related employment at any aerospace or other company,
or division thereof, which is not competitive with the business of SPDV.
                  (2) Employee shall not, for a period of 24 months following
such termination solicit or cause or authorize directly or indirectly to be
solicited for or on behalf of himself or any third party any customer of SPDV to
provide to that customer goods or services directly competitive with the goods
or services provided to that customer by SpaceDev. Nothing set forth herein
shall prevent Employee following termination of this Agreement from securing any
engineering related employment at any aerospace or other company, or division
thereof, which is not competitive with or providing services to SPDV.
         (e) If the covenants contained in this Section 8 are violated, or
threatened to be violated, Employee acknowledges and agrees that such violation
or threatened violation will cause irreparable damage to the Company and SPDV,
that the remedy at law of the Company or of SPDV will be inadequate and that the
Company and SPDV shall, in addition to, but not in limitation of, any other
rights or remedies available at law or in equity, be entitled to temporary and

                                      -9-
<PAGE>

permanent injunctive relief and/or specific performance without the necessity of
proving actual damage.
         (f) Employee acknowledges that the provisions of this Section 8 are
fair and equitable and are required in connection with the Acquisition and
continued employment hereunder. The parties hereto acknowledge that the
provisions of this Section 8 shall survive the termination of this Agreement.
         9. EMPLOYEE'S RIGHTS AND BENEFITS PERSONAL. Except as may herein
otherwise be specifically provided, the rights, benefits and obligations of
Employee under this Agreement are personal to Employee, and no such rights or
benefits shall be subject to voluntary or involuntary alienation, assignment or
transfer.
         10. ENTIRE AGREEMENT; MODIFICATION; WAIVER. This Agreement constitutes
the entire agreement between the parties pertaining to the subject matter
contained in it and supersedes all prior written or oral agreements,
representations, understandings and/or discussion between the parties relating
thereto. No supplement, modification or amendment of this Agreement shall be
binding unless executed in writing by the party making the waiver.
         11. NOTICES. Any notice required or permitted hereunder shall be given
in writing and shall be conclusively deemed effectively given upon personal
delivery, or three (3) business days after deposit in the United States mail, by
registered or certified mail (or air mail, if notice shall be sent outside the

         12. EFFECT OF HEADINGS. The subject headings of this Agreement are
included for purposes of convenience only, and shall not affect the construction
or interpretation of any of its provisions.
         13. ARBITRATION; ATTORNEYS' FEES. Any controversy or claim arising out
of or to this Agreement, or the breach hereof, shall be resolved by
JAMS/ENDispute in accord with its rules and regulations and judgment on the
award so rendered may be entered in any court having jurisdiction thereof. Any
such proceeding shall be had in the County of San Diego, State of California. If
any action or proceeding is brought to enforce any provisions of this Agreement,
the prevailing party shall be entitled to its costs and expenses in connection

<PAGE>

agreements, duties or obligations hereunder, the Company would suffer great and
irreparable harm, injury and damage, the Company would encounter extreme
difficulty in attempting to prove the actual amount of damages suffered by the
Company as a result of such breach, and the Company would not be reasonably or
adequately compensated by an award of damages in any action at law. Employee
therefore acknowledges and agrees that, in addition to any other remedy the
Company may have at law, in equity, by statute or otherwise, in the event of any
breach by Employee of any of his covenants, agreements, duties or obligations
hereunder, the Company shall be entitled to seek and receive temporary,
preliminary and permanent injunctive and other equitable relief from any court
of competent jurisdiction to enforce any of the rights of the Company, or any of
the covenants, agreements, duties or obligations of Employee hereunder, and/or
otherwise to prevent the violation of any of the terms or provisions hereof, all
without the necessity of proving the amount of any actual damage to the Company
or any affiliate thereof resulting therefrom; PROVIDED, HOWEVER, that nothing
contained in this Section 14 shall be deemed or construed in any manner
whatsoever as a waiver by the Company of any of the rights which the Company may
have against Employee at law, in equity, by statute or otherwise arising out of,
in connection with or resulting from the breach by Employee of any of his
covenants, agreements, duties or obligations hereunder.
         15. APPLICABLE LAW. The validity, interpretation and enforcement of
this Agreement shall be governed by the laws of the State of California except
that the Federal Arbitration Act shall govern any arbitration proceeding.

         16. COUNTERPARTS. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which when
taken together shall constitute one and the same Agreement.
         17. SEVERABILITY. If any provision of this Agreement shall be declared
invalid, illegal and/or unenforceable, such provision shall be severed and the
remaining provisions shall continue in full force and effect.
         18. SUCCESSOR AND ASSIGNS. The provisions hereof shall inure to the
benefit of, be binding upon, and be enforceable by the successors and assigns of
the Company.
         19. ASSIGNMENT; SUCCESSORS; AFFILIATES. The Company may assign this
Agreement (or the interest of the Company herein) to any affiliate of the
Company or to any entity which is a party to a merger, reorganization, or
consolidation with the Company or to a subsidiary of the Company or to an entity
or entities acquiring substantially all of the assets of the Company or of any

specified in this Agreement, to or for the benefit of any affiliate of the
Company, including, without limitation, any parent or subsidiary of the Company

Agreement, any rights under this Agreement or any duties imposed under this
Agreement nor shall Employee (or Employee's spouse, heirs, beneficiaries,

                                      -13-

administrators or executors) have the right to pledge, hypothecate or otherwise
encumber Employee's right to receive compensation hereunder without the consent
of the Company.

<PAGE>

         2. VESTING AND TERM OF OPTION. This Option is not exercisable in any
part until one (1) year after the Date of Grant, and then only upon achievement
of the Triggering Events set forth below:

         (a) After the Company has constructed, completed and tested its first
spacecraft and certified that it is "ready to launch," the Option shall vest in
the Grantee to the extent of 20,000 shares optioned hereunder at an exercise
price of $1.50 per share;

         (b) When the Company has generated $750,000 in pretax profits in any
one fiscal year from customers and business developed from the Integrated Space

services, the Option shall vest in the Grantee to the extent of an additional
20,000 shares optioned hereunder at an exercise price of $ 2.00 per share;

         (c) On the successful launch of the Company's first Spacecraft, the

Option shall vest in the Grantee to the extent of an additional 20,000 shares
optioned hereunder at an exercise price of $3.50 per share;

         Upon the occurrence of any Triggering Event, subject to the other
provisions of this Option, Grantee may exercise this Option for all or any
portion of the number of shares optioned for which the Option is then vested.
Subject to the other provisions hereof, each Option shall have a total term of
seven (7) years from Date of Grant, and upon expiration of such seven (7) year
term, any Option not exercised in full shall expire and may thereafter no longer
be exercised.

         3. RESTRICTIONS ON EXERCISE. The following additional restrictions
shall apply to the exercise of the Option:

                  (a) TERMINATION OF EMPLOYMENT. If the Grantee's employment by
the Company or any of its subsidiaries is terminated for any reason other than
death, only that portion of this Option exercisable at the date of such
termination of employment may thereafter be exercised, and it may not be
exercised more than three (3) months after such date of termination nor after
the expiration date of this Option, whichever date is sooner, unless such

                                                            Page 2
<PAGE>

termination is due to the Grantee's permanent and total disability, in which
case such period of three (3) months shall be extended to one (1) year. In all
other respects, this Option shall terminate upon such termination of employment.

                  (b) DEATH OF GRANTEE. If the Grantee shall die during the term
of this Option, the Grantee's legal representative or representatives, or the
person or persons entitled to do so under the Grantee's last will and testament
or under applicable intestate law, shall have the right to exercise this Option,
but only for the number of shares as to which the Grantee was entitled to
exercise this Option in accordance with Section 2 hereof on the date of his
death, and such right shall expire and this Option shall terminate one (1) year
after the date of the Grantee's death or on the expiration date of this Option,
whichever date is sooner. In all other respects, this Option shall terminate
upon such termination of employment.

         4. NON-TRANSFERABLE. The Grantee may not transfer this Option except by
will or the laws of descent and distribution. This Option shall not be otherwise
transferable, assigned, pledged, hypothecated or disposed of in any way, whether
by operation of law or otherwise, and shall be exercised during the Grantee's
lifetime only by the Grantee or his guardian or legal representative.

         5. ADJUSTMENTS AND CORPORATE REORGANIZATIONS. If the outstanding shares
of the class then subject to this Option are increased or decreased, or are
changed into or exchanged for a different number or kind of shares or
securities, as a result of one or more reorganizations, recapitalizations, stock
splits, reverse stock splits, stock dividends or the like, appropriate
adjustments shall be made in the number and/or kind of shares or securities for
which the unexercised portions of this Option may thereafter be exercised, all
without any change in the aggregate exercise price applicable to the unexercised
portions of this Option, but with a corresponding adjustment in the exercise
price per share or other unit. No fractional share of stock shall be issued
under this Option or in connection with any such adjustment. Such adjustments
shall be made by or under authority of the Company's Board of Directors whose
determinations as to what adjustments shall be made, and the extent thereof,
shall be final, binding and conclusive.

            Upon the dissolution or liquidation of the Company, or upon a
reorganization, merger or consolidation of the Company as a result of which the
outstanding securities of the class then subject to this Option are changed into
or exchanged for cash or property or securities not of the Company's issue, or
upon a sale of substantially all the property of the Company to, or the
acquisition of stock representing more than eighty percent (80%) of the voting
power of the stock of the Company then outstanding by another corporation or
person, this Option shall terminate, unless provision be made in writing in
connection with such transaction for the assumption of options theretofore
granted, or the substitution for such options of any options covering the stock
of a successor corporation, or a parent or subsidiary thereof, which appropriate
adjustments as to the number and kind of shares and prices, in which event this
Option shall continue in the manner and under the terms so provided. If this
Option shall terminate pursuant to the foregoing sentence, the Grantee shall

                                                            Page 3
<PAGE>

have the right, at such time prior to the consummation of the transaction
causing such termination to exercise the unexercised portions of this Option.

         6. MANNER OF EXERCISE. This Option may be exercised by the Grantee or
other person then entitled to exercise it by giving four (4) business days'
written notice of exercise to the Company specifying the number of shares to be
purchased and the total purchase price, accompanied by a check to the order of
the Company in payment of such price. If the Company is required to withhold on
account of any present or future tax imposed as a result of such exercise, the
notice of exercise shall be accompanied by a check to the order of the Company
in payment of the amount of such withholding.

         7. ALTERNATIVE PAYMENT WITH STOCK. Notwithstanding the foregoing
provisions requiring payment by check, payment of such purchase price or any
portion thereof may be made with shares of stock of the same class as the shares
then subject to this Option, if shares of that class are then publicly traded
(as defined below), such shares to be credited toward such purchase price on the
valuation basis set forth below, in which event the stock certificates
evidencing the shares so to be used shall accompany the notice of exercise and
shall be duly endorsed or accompanied by duly executed stock powers to transfer
the same to the Company; provided, however, that such payment in stock instead
of cash shall not be effective and shall be rejected by the Company if (i) the
Company is then prohibited from purchasing or acquiring shares of the class of
its stock thus tendered to it, or (ii) the right or power of the person
exercising the Option to deliver such shares in payment of said purchase price
is subject to the prior interests of any other person (excepting the Company),
as indicated by legends upon the certificate(s) or as known to the Company. For
purposes of this paragraph: (a) "publicly traded" shares are those which are
listed or admitted to unlisted trading privileges on a national securities
exchange or as to which bid and offer quotations are reported in the automated
quotation system ("NASDAQ") operated by the National Association of Securities
Dealers, Inc. ("NASD") and (b) for credit toward the purchase price, shares so
surrendered shall be valued as of the day immediately preceding the delivery to
the Company of the certificate(s) evidencing such shares (or, if such day is not
a trading day in the U.S. securities markets, on the nearest preceding trading
day), on the basis of the closing price of stock of the class as reported with
respect to the market (or the composite of the markets, if more than one) in
which such shares are then traded or, if no such closing prices are reported,
the lowest independent offer quotation reported therefor in Level 2 of NASDAQ,
or, if no such quotations are reported, on the basis of the most nearly
comparable valuation method acceptable to the Company.

         8. RIGHTS IN SHARES BEFORE ISSUANCE AND DELIVERY. No person shall be
entitled to the privileges of stock ownership in respect of any shares issuable
upon exercise of this Option, unless and until such shares have been issued to
such person as fully paid shares.

         9. REQUIREMENTS OF LAW AND OF STOCK EXCHANGES. By accepting this
Option, the Grantee represents and agrees for himself and his transferees by
will or the laws of descent and distribution that, unless a registration
statement under the Securities Act of 1933 is in effect as to shares purchased

                                                            Page 4
<PAGE>

upon any exercise of this Option, (i) any and all shares so purchased shall be
acquired for his personal account and not with a view to or for sale in
connection with any distribution, and (ii) each notice of the exercise of any
portion of this Option shall be accompanied by a representation and warranty in
writing, signed by the person entitled to exercise the same, that the shares are
being so acquired in good faith for his personal account and not with a view to
or for sale in connection with any distribution.

                  No certificate or certificates for shares of stock purchased
upon exercise of this Option shall be issued and delivered prior to the
admission of such shares to listing on notice of issuance on any stock exchange
on which shares of that class are then listed, nor unless and until, in the
opinion of counsel for the Company, such securities may be issued and delivered
without causing the Company to be in violation of or incur any liability under
any federal, state or other securities law, any requirement of any securities
exchange listing agreement to which the Company may be a party, or any other
requirement of law or of any regulatory body having jurisdiction over the
Company.

         10. EMPLOYMENT BY THE COMPANY. Nothing contained in this Option shall
be construed to confer upon Grantee any right to be continued in the employ of
the Company or any of its subsidiaries, or to limit the right of the Company or
any subsidiary to retire, request the resignation of or discharge Grantee as an
employee at any time, with or without cause.

         11. STOCK OPTION PLAN. This Option is subject to, and the Company and
the Grantee agree to be bound by, all of the terms and conditions of any Plan
adopted by the Board of Directors and Shareholders for this Option to qualify
under a corporate Stock Purchase Plan Option or Incentive Stock Option as
defined in Internal Revenue Code sections 421, 422, 423, provided that no such
plan adopted by the Company shall deprive Grantee, without his consent, of this
Option or any of his rights hereunder. If all or any part of the Options shall
not qualify under any such future Plan adopted by the Company the Options shall
nevertheless be valid and carried into effect. The Board of Directors of the
Company or its Committee established for the purpose of adopting such a Plan is
vested with final authority to adopt, interpret and construe any such Plan. A
copy of any such Plan, and any future amendments thereto, shall be distributed
to the Grantee immediately upon adoption and be available for inspection during
business hours by the Grantee or other persons entitled to exercise this Option
at the Company's principal office.

         12. RESTRICTED STOCK. Grantee agrees, recognizes, and acknowledges that
any stock issued to him pursuant to his exercise of this Option shall be subject
to the terms and conditions as may be issued by the Securities and Exchange
Commission in connection with future public offering of the stock of the
Company.

         13. NOTICES. Any notice to be given to the Company shall be addressed
to the Company in care of its Secretary at its principal office, and any notice
to be given to the Grantee shall be addressed to him at the address given
beneath his signature hereto or at such other address as the Grantee may

                                                            Page 5
<PAGE>

hereafter designate in writing to the Company. Any such notice shall be deemed
duly given when enclosed in a properly sealed envelope addressed as aforesaid,
registered or certified mail, and deposited, postage and registry or
certification fee prepaid, in a post office or branch post office regularly
maintained by the United States Postal Service.







         IN WITNESS WHEREOF, the Company has granted this Option on the Date of
Grant specified above.

                              --------------------

         This EMPLOYMENT AGREEMENT (the "Agreement") is entered into as of the
7th day of February, 1998, by and between Integrated Space Systems, Inc., a
California corporation (the "Company"), and Philip Smith ("Employee").

                                 RECITALS

         A. The Company is principally engaged in the business of providing
engineering analysis, design, test support and field engineering for
aerospace-related projects.
         B. Effective this date, SpaceDev, Inc., a Colorado corporation ("SPDV")
has acquired all of the issued and outstanding capital stock of the Company (the
"Acquisition"). In connection with and as a material condition to completion of
the Acquisition, certain shareholders and management employees of the Company,
including Employee, have agreed to enter into employment agreements with the
Company.
         C. The Company desires to retain Employee as Chief Operating Officer of
the Company, and Employee desires to accept such employment on the terms and
conditions set forth herein.
         NOW, THEREFORE, based upon the following covenants, conditions and
promises the parties hereto do hereby agree as follows:

                                       -1-
<PAGE>

         1. EMPLOYMENT AND DUTIES. Subject to the terms and conditions set forth
herein, the Company hereby employs Employee, and Employee hereby accepts such
employment with the Company, as the Chief Operating Officer of the Company, and
his duties shall be consistent with such positions.
         2. TERM OF EMPLOYMENT. The term of Employee's employment under this
Agreement shall commence on and as of the date hereof and shall continue
hereafter for a period of 36 months, subject to early termination as provided
for elsewhere in this Agreement. The "term" of this Agreement shall mean and
refer to such 36-month period (or any earlier termination thereof pursuant to
Section 5 hereof).
         3. EXTENT OF SERVICE. During the term hereof, Employee agrees to and
shall devote his full time to the performance of his duties hereunder, it being
the intent of the parties hereto that Employee shall devote his best efforts to
furthering, promoting and developing the business, activities and interests of
the Company. Employee acknowledges that the "interests of the Company" include
the business, activities and interests of SPDV, its subsidiaries and affiliates,
and as a result, Employee may also be requested by the Chief Executive Officer
or Board of Directors of the Company to undertake various management
responsibilities on a full- or part-time basis for or on behalf of SPDV for all
or part of the term.
         4. COMPENSATION. As compensation for the services which Employee is to
render hereunder, the Company shall pay Employee the following aggregate annual
salary for and with respect to each year (annual periods ending with the
anniversary date of the date of this Agreement)during the term hereof: $60,000
for the first year, $90,000 for the second year and $110,000 for the third year.

<PAGE>

Employee's salary during each of such years shall be paid in accordance with the
normal payroll practices of the Company. At the end of each year during the term
hereof, the Board of Directors of the Company may review the compensation of
Employee hereunder and if it, in its sole discretion, believes it to be
justified, may pay to Employee a cash bonus for and with respect to such year.
                  (a) The Company will provide Employee with such fringe
benefits as are within the Company's policy as approved by the Board of
Directors of the Company. The Company shall also reimburse Employee for expenses
reasonably incurred by him in carrying out his duties hereunder, including
travel, lodging and reasonable entertainment expenses, promptly after
presentation to the Company of receipts or other documents evidencing the
incurrence of such expenses providing that such expenses have been approved in
advance by the Chief Executive Officer of the Company or are otherwise
consistent with policy on such matters as established by the Company's Board of
Directors.
                  (b) The Company shall cause SPDV to grant to Employee options
to purchase shares of common stock of SPDV in the amounts and upon the terms set
forth in Exhibit A attached hereto and incorporated herein by this reference.
         5. TERMINATION OF EMPLOYMENT FOR GOOD CAUSE. The Company may terminate
the employment of Employee for "good cause" by giving written notice thereof to
Employee. For the purposes of this Agreement, "good cause" shall mean only

hereunder, (ii) commission of a crime directly related to his employment
hereunder, (iii) conviction of a felony involving moral turpitude, (iv)

business and affairs of the Company or failure to perform such duties as may
reasonably be directed by the Board of Directors and as may be reasonably
consistent with the duties and obligations of Employee's office, or (v) breach
of any material provision of this Agreement. In the event the employment of the
Employee is terminated pursuant to this Section 5, the Company shall have no
further liability to Employee other than for compensation earned but not yet
paid. In the event the Company contends that it had good cause to terminate the
employment of Employee pursuant to clause (i), (ii) or (iii) of this Section 5,
the Company shall specify in said written notice the effective date of
termination of Employee's employment, which date may, in the Company's sole
discretion, be the date of such notice. In the event the Company contends that
it has good cause to terminate the employment of Employee pursuant to clause
(iv) or (v) of this Section 5, the Company shall set forth in said written
notice reasonable details of Employee's acts or conduct which the Company
alleges constitutes a willful and gross mismanagement of business and affairs of
the Company or a breach of material provision of this Agreement, as the case may
be. The written notice shall also specify what, if anything, Employee could do
to cure or eliminate the alleged "good cause" for termination if the matter is
susceptible of cure. If Employee performs the required services or modifies
Employee's performance to correct the matters complained of within sixty (60)
days of receipt of the notice, Employee's breach will be deemed cured. However,
if the nature of the matters complained of are such that more than sixty (60)
days are reasonably required to correct the matters complained of, then his
breach will be deemed cured if he commences to correct such matters within the

                                      -4-
<PAGE>

sixty (60) day period and thereafter diligently prosecutes such correction to
completion, but not to exceed one additional sixty (60) day period. If Employee
does not modify his performance to correct or commence to correct the matter
complained of within the sixty (60) day period or any extension thereof, the
Company shall have the right to terminate this Agreement at the end of such (60)
day period or any extension thereof. It is understood that Employee's
performance hereunder shall not be deemed unsatisfactory solely on the basis of
any economic performance of the Company because such performance will depend in
part on a variety of factors over which Employee has little control.
         6. TERMINATION BY DEATH OR INCAPACITY. The Company may terminate the
employment of Employee by written notice to Employee if, during the term of this
Agreement, Employee shall become incapable of fulfilling his obligations
hereunder because of injury or physical or mental illness which shall exist or
may reasonably be anticipated to exist for a period of six (6) consecutive
months or for an aggregate of six (6) months during the term hereof. The death
of Employee shall automatically terminate the term of Employee's employment. In
the event the employment of Employee is terminated by Employee's death or by the
Company pursuant to this Section 6 because of injury or physical or mental
illness, the Company shall pay Employee, or Employee's heir(s) (in the event of
death), all compensation of Employee earned but not yet paid up to and through
the day upon which Employee's death occurs or this Agreement is terminated by
the Company due to Employee's incapacity, as applicable, or in accordance with
any written policy applicable to other executives of the Company in effect at
the time of Employee's death or incapacity, if more favorable.

                                      -5-
<PAGE>

         7. TERMINATION WITHOUT CAUSE. The Company may terminate the employment
of Employee without cause at any time in which event Employee and the Company
agree that the sole amounts due and owing to Employee hereunder (whether as
"severance pay" or otherwise) shall be $100,000, $70,000 or $60,000 for a
termination of employment without cause during year one, year two or year three
of the term, respectively.
         8. NONCOMPETITION; NONSOLICITATION; CONFIDENTIAL INFORMATION.
         (a) Employee covenants and agrees that, during the term he will not,
directly or indirectly, whether individually or as an officer, director,
employee or consultant, become employed by, or become a partner in or a
stockholder owning more than one percent (1%) of, any business which is engaged
in the business of providing aerospace engineering services and other related
consulting or any other business which is similar to or competitive with the
business now or at any time during the term of this agreement being conducted by
SPDV and/or the Company.
         (b) Employee acknowledges that it is the policy of the Company (for
purposes of this subsection 8 (b) the term "Company" shall also, refer to SPDV,
any subsidiary, parent or other affiliate of the Company or of SPDV) to maintain
as secret and confidential all valuable and unique information heretofore or
hereafter acquired, developed or used by the Company relating to the business,
operations, employees and/or clients of the Company, including SPDV, which gives
the Company a competitive advantage in its industry, including, without
limitation: information about net costs, profits, markets, suppliers,
technology, key personnel and consultants, pricing policies, operational
methods, designs, technical and systems processes, relationships with
universities, the National Aeronautics and Space Administration and other

                                      -6-
<PAGE>

governmental agencies, and other business affairs and methods and other
information not readily available to the public, plans for future developments,
operating manuals, financial statements, forecasts and operating data and
business plans (all such information is hereinafter referred to as "Confidential
Information"). Employee recognizes and acknowledges that the services heretofore
performed by Employee and those to be performed by Employee are special and
unique, and that by reason of his duties, he has acquired and will acquire
Confidential Information. Employee recognizes that all such Confidential
Information is the property of the Company. In consideration of the Company's
entering into this Agreement, Employee agrees that: (i) Employee shall never,
directly or indirectly, use, publish, disseminate or otherwise disclose any
Confidential Information obtained during his employment by the Company (whether
obtained prior to, during or after the term of this Agreement) without the prior
written consent of the Company's Board of Directors; and (ii) during the term of
this Agreement, he shall exercise all due and diligent precautions to protect
the integrity of the Company's designs, processes, systems, know-how,
statistical data and compilations, agreements, contracts, manuals or other
documents embodying any Confidential Information. Upon termination of Employee's
employment by the Company and at any other time upon request of the Company, he
shall return all such documents (and copies thereof) embodying any Confidential
Information in his possession or control. Employee agrees that the provisions of
this subparagraph (b) are reasonable and necessary to protect the proprietary
rights of the Company in the Confidential Information and its trade secrets,
goodwill and reputation. The provisions of this subparagraph (b) shall not apply

                                      -7-
<PAGE>

to Confidential Information (i) which is known generally to the public, (ii)
which otherwise comes into the public domain without the fault of Employee, or
(iii) which Employee obtains from sources other than the Company.
         (c) For a period of 36 months after the termination of this Agreement
for any reason other than a termination by the Company under Section 7 (or for
such a lesser period of time as may be determined by a court of law or equity to
be a reasonable limitation on Employee), Employee shall not: (i) solicit,
directly or indirectly, any director, officer or employee of the Company to
discontinue that individual's status of employment with the Company; (ii) become
employed in any activity similar to or competitive with the business of the
Company or of SPDV being conducted at the time of termination of this Agreement
anywhere in the world; or (iii) solicit or cause or authorize, directly or
indirectly to be solicited, for or on behalf of himself or any third party, from
customers, clients, consultants or other providers of goods and services (all of
whom are collectively referred to as "Company Clients") of the Company or of
SPDV, any business which is competitive with the Company or with SPDV anywhere
in the world. "Clients" shall also include persons whom or entities which the
Company has identified and targeted (at or prior to the date of termination of
this Agreement) as intended customers or clients of SPDV
         (d) In the event of a termination by the Company under Section 7 of
this agreement clauses (ii) and (iii) of subsection 8 (c) above shall be
adjusted as follows:
                  (1) Employee shall not, for a period of 18 months following
such termination: (i) become an officer or director, or maintain an ownership
interest of more than one percent in any company that is directly competitive

                                      -8-
<PAGE>

with the business of SPDV; or (ii) be employed by or consult to any business
which is directly competitive with SPDV anywhere in the world. Nothing set forth
herein shall prevent Employee following termination of this Agreement from
securing any engineering related employment at any aerospace or other company,
or division thereof, which is not competitive with the business of SPDV.
                  (2) Employee shall not, for a period of 24 months following
such termination solicit or cause or authorize directly or indirectly to be
solicited for or on behalf of himself or any third party any customer of SPDV to
provide to that customer goods or services directly competitive with the goods
or services provided to that customer by SpaceDev. Nothing set forth herein
shall prevent Employee following termination of this Agreement from securing any
engineering related employment at any aerospace or other company, or division
thereof, which is not competitive with or providing services to SPDV.
         (e) If the covenants contained in this Section 8 are violated, or
threatened to be violated, Employee acknowledges and agrees that such violation
or threatened violation will cause irreparable damage to the Company and SPDV,
that the remedy at law of the Company or of SPDV will be inadequate and that the
Company and SPDV shall, in addition to, but not in limitation of, any other
rights or remedies available at law or in equity, be entitled to temporary and
permanent injunctive relief and/or specific performance without the necessity of
proving actual damage.
         (f) Employee acknowledges that the provisions of this Section 8 are
fair and equitable and are required in connection with the Acquisition and
continued employment hereunder. The parties hereto acknowledge that the
provisions of this Section 8 shall survive the termination of this Agreement.

         9. EMPLOYEE'S RIGHTS AND BENEFITS PERSONAL. Except as may herein
otherwise be specifically provided, the rights, benefits and obligations of
Employee under this Agreement are personal to Employee, and no such rights or
benefits shall be subject to voluntary or involuntary alienation, assignment or
transfer.

the entire agreement between the parties pertaining to the subject matter
contained in it and supersedes all prior written or oral agreements,
representations, understandings and/or discussion between the parties relating
thereto. No supplement, modification or amendment of this Agreement shall be
binding unless executed in writing by the party making the waiver.
         11. NOTICES. Any notice required or permitted hereunder shall be given
in writing and shall be conclusively deemed effectively given upon personal
delivery, or three (3) business days after deposit in the United States mail, by
registered or certified mail (or air mail, if notice shall be sent outside the
United States), return receipt requested, postage prepaid, or two (2) days after
delivery to a nationally known air courier or delivery company, addressed to the

         If to Employee, to:                Philip Smith

         12. EFFECT OF HEADINGS. The subject headings of this Agreement are
included for purposes of convenience only, and shall not affect the construction
or interpretation of any of its provisions.
         13. ARBITRATION; ATTORNEYS' FEES. Any controversy or claim arising out
of or to this Agreement, or the breach hereof, shall be resolved by
JAMS/ENDispute in accord with its rules and regulations and judgment on the
award so rendered may be entered in any court having jurisdiction thereof. Any
such proceeding shall be had in the County of San Diego, State of California. If
any action or proceeding is brought to enforce any provisions of this Agreement,
the prevailing party shall be entitled to its costs and expenses in connection
therewith, including without limitation reasonable attorneys' fees.
         14. INJUNCTIVE RELIEF. Employee hereby recognizes, acknowledges and
agrees that in the event of any breach by Employee of any of his covenants,
agreements, duties or obligations hereunder, the Company would suffer great and
irreparable harm, injury and damage, the Company would encounter extreme
difficulty in attempting to prove the actual amount of damages suffered by the
Company as a result of such breach, and the Company would not be reasonably or
adequately compensated by an award of damages in any action at law. Employee
therefore acknowledges and agrees that, in addition to any other remedy the
Company may have at law, in equity, by statute or otherwise, in the event of any

                                      -11-
<PAGE>

breach by Employee of any of his covenants, agreements, duties or obligations
hereunder, the Company shall be entitled to seek and receive temporary,
preliminary and permanent injunctive and other equitable relief from any court
of competent jurisdiction to enforce any of the rights of the Company, or any of
the covenants, agreements, duties or obligations of Employee hereunder, and/or
otherwise to prevent the violation of any of the terms or provisions hereof, all
without the necessity of proving the amount of any actual damage to the Company
or any affiliate thereof resulting therefrom; PROVIDED, HOWEVER, that nothing
contained in this Section 14 shall be deemed or construed in any manner
whatsoever as a waiver by the Company of any of the rights which the Company may
have against Employee at law, in equity, by statute or otherwise arising out of,
in connection with or resulting from the breach by Employee of any of his
covenants, agreements, duties or obligations hereunder.
         15. APPLICABLE LAW. The validity, interpretation and enforcement of
this Agreement shall be governed by the laws of the State of California except
that the Federal Arbitration Act shall govern any arbitration proceeding.
         16. COUNTERPARTS. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which when
taken together shall constitute one and the same Agreement.
         17. SEVERABILITY. If any provision of this Agreement shall be declared
invalid, illegal and/or unenforceable, such provision shall be severed and the
remaining provisions shall continue in full force and effect.
         18. SUCCESSOR AND ASSIGNS. The provisions hereof shall inure to the

                                      -12-

benefit of, be binding upon, and be enforceable by the successors and assigns of
the Company.
         19. ASSIGNMENT; SUCCESSORS; AFFILIATES. The Company may assign this
Agreement (or the interest of the Company herein) to any affiliate of the
Company or to any entity which is a party to a merger, reorganization, or
consolidation with the Company or to a subsidiary of the Company or to an entity
or entities acquiring substantially all of the assets of the Company or of any
division with respect to which Employee is providing services (providing any
such assignee assumes the Company's obligation under the Agreement). Employee
shall, if requested by the Company, perform Employee's services and duties, as
specified in this Agreement, to or for the benefit of any affiliate of the
Company, including, without limitation, any parent or subsidiary of the Company
or any other subsidiary of any parent of the Company. Upon such assignment,
acquisition, merger, consolidation, or reorganization, the term "Company" as
used herein shall be deemed to refer to such assignee or such successor entity.
Employee shall not have the right to assign Employee's interest in this
Agreement, any rights under this Agreement or any duties imposed under this
Agreement nor shall Employee (or Employee's spouse, heirs, beneficiaries,
administrators or executors) have the right to pledge, hypothecate or otherwise
encumber Employee's right to receive compensation hereunder without the consent
of the Company.
         20. FURTHER ASSURANCES. The Company and Employee each agree to execute
and deliver any and all additional instruments and to perform any and all
additional acts deemed by either party to be necessary or proper to carry into
effect the terms, conditions and provisions of this Agreement.

two (2) consecutive fiscal years from customers or business developed from the
Integrated Space Systems' ("ISS") base of business and/or business developed
from such base or services (and not from any other business of the Company), the
Option shall vest in the Grantee to the extent of an additional 20,000 shares
optioned hereunder at an exercise price of $ 3.50 per share;

         Upon the occurrence of any Triggering Event, subject to the other
provisions of this Option, Grantee may exercise this Option for all or any
portion of the number of shares optioned for which the Option is then vested.
Subject to the other provisions hereof, each Option shall have a total term of
seven (7) years from Date of Grant, and upon expiration of such seven (7) year
term, any Option not exercised in full shall expire and may thereafter no longer
be exercised.

         3. RESTRICTIONS ON EXERCISE. The following additional restrictions
shall apply to the exercise of the Option:

                  (a) TERMINATION OF EMPLOYMENT. If the Grantee's employment by
the Company or any of its subsidiaries is terminated for any reason other than
death, only that portion of this Option exercisable at the date of such
termination of employment may thereafter be exercised, and it may not be
exercised more than three (3) months after such date of termination nor after
the expiration date of this Option, whichever date is sooner, unless such
termination is due to the Grantee's permanent and total disability, in which
case such period of three (3) months shall be extended to one (1) year. In all
other respects, this Option shall terminate upon such termination of employment.

                  (b) DEATH OF GRANTEE. If the Grantee shall die during the term
of this Option, the Grantee's legal representative or representatives, or the
person or persons entitled to do so under the Grantee's last will and testament
or under applicable intestate law, shall have the right to exercise this Option,

                                                            Page 2
<PAGE>

but only for the number of shares as to which the Grantee was entitled to
exercise this Option in accordance with Section 2 hereof on the date of his
death, and such right shall expire and this Option shall terminate one (1) year
after the date of the Grantee's death or on the expiration date of this Option,
whichever date is sooner. In all other respects, this Option shall terminate
upon such termination of employment.

         4. NON-TRANSFERABLE. The Grantee may not transfer this Option except by
will or the laws of descent and distribution. This Option shall not be otherwise
transferable, assigned, pledged, hypothecated or disposed of in any way, whether
by operation of law or otherwise, and shall be exercised during the Grantee's
lifetime only by the Grantee or his guardian or legal representative.

         5. ADJUSTMENTS AND CORPORATE REORGANIZATIONS. If the outstanding shares
of the class then subject to this Option are increased or decreased, or are
changed into or exchanged for a different number or kind of shares or
securities, as a result of one or more reorganizations, recapitalizations, stock
splits, reverse stock splits, stock dividends or the like, appropriate
adjustments shall be made in the number and/or kind of shares or securities for
which the unexercised portions of this Option may thereafter be exercised, all
without any change in the aggregate exercise price applicable to the unexercised
portions of this Option, but with a corresponding adjustment in the exercise
price per share or other unit. No fractional share of stock shall be issued
under this Option or in connection with any such adjustment. Such adjustments
shall be made by or under authority of the Company's Board of Directors whose
determinations as to what adjustments shall be made, and the extent thereof,
shall be final, binding and conclusive.

            Upon the dissolution or liquidation of the Company, or upon a
reorganization, merger or consolidation of the Company as a result of which the
outstanding securities of the class then subject to this Option are changed into
or exchanged for cash or property or securities not of the Company's issue, or
upon a sale of substantially all the property of the Company to, or the
acquisition of stock representing more than eighty percent (80%) of the voting
power of the stock of the Company then outstanding by another corporation or
person, this Option shall terminate, unless provision be made in writing in
connection with such transaction for the assumption of options theretofore
granted, or the substitution for such options of any options covering the stock
of a successor corporation, or a parent or subsidiary thereof, which appropriate
adjustments as to the number and kind of shares and prices, in which event this
Option shall continue in the manner and under the terms so provided. If this
Option shall terminate pursuant to the foregoing sentence, the Grantee shall
have the right, at such time prior to the consummation of the transaction
causing such termination to exercise the unexercised portions of this Option.

         6. MANNER OF EXERCISE. This Option may be exercised by the Grantee or
other person then entitled to exercise it by giving four (4) business days'
written notice of exercise to the Company specifying the number of shares to be
purchased and the total purchase price, accompanied by a check to the order of
the Company in payment of such price. If the Company is required to withhold on

                                                            Page 3
<PAGE>

account of any present or future tax imposed as a result of such exercise, the
notice of exercise shall be accompanied by a check to the order of the Company
in payment of the amount of such withholding.

         7. ALTERNATIVE PAYMENT WITH STOCK. Notwithstanding the foregoing
provisions requiring payment by check, payment of such purchase price or any
portion thereof may be made with shares of stock of the same class as the shares

surrendered shall be valued as of the day immediately preceding the delivery to
the Company of the certificate(s) evidencing such shares (or, if such day is not

day), on the basis of the closing price of stock of the class as reported with
respect to the market (or the composite of the markets, if more than one) in

comparable valuation method acceptable to the Company.

         8. RIGHTS IN SHARES BEFORE ISSUANCE AND DELIVERY. No person shall be

         9. REQUIREMENTS OF LAW AND OF STOCK EXCHANGES. By accepting this
Option, the Grantee represents and agrees for himself and his transferees by

upon any exercise of this Option, (i) any and all shares so purchased shall be
acquired for his personal account and not with a view to or for sale in
connection with any distribution, and (ii) each notice of the exercise of any

consultant has been or will be prevented from properly performing his duties
under this Agreement for more than sixty (60) days in any twelve month period as
a result of any physical or mental incapacity then, to the extent permitted by
law, SPDV may terminate the Period of Employment upon two (2) weeks' advance

period; thereafter, all obligations of SPDV under this Agreement shall cease.
Nothing in this Section shall affect King's rights under any applicable SPDV
corporate disability plan, if one exists at the time of Kings' termination.

(c) By Employer Not For Cause. At any time, SPDV may terminate King for any
reason, with or without cause, by providing King thirty (30) days' advance
written notice. SPDV shall have the option, in its complete discretion, to
terminate King at any time prior to the end of such notice period, provided SPDV
pays and delivers to King all compensation and shares of stock due and owing
through the last day actually worked, plus an amount equal to the base salary
and shares of stock under Section 3 King would have earned through the balance
of the above notice period; thereafter, all of SPDV's obligations under this
Agreement shall cease. SPDV may dismiss King without cause notwithstanding
anything to the contrary contained in or arising from any statements, policies,
or practices of SPDV relating to the employment, discipline, or termination of
its employees.

(d) By Employer For Cause. At any time, and without prior notice, SPDV may
terminate King for Cause (as defined below). SPDV shall pay and deliver to King
all compensation and shares of stock then due and owing; thereafter, all of
SPDV's obligations under this Agreement shall cease. Termination shall be for
"Cause" if King: (1) acts in bad faith and to the detriment of SPDV; (2) refuses
or fails to act in accordance with any specific appropriate direction or order
of SPDV; (3) exhibits in regard to his employment unfitness or unavailability
for service, misconduct, dishonesty, habitual neglect, or incompetence; (4) is
convicted of a crime. If termination is due to King's disability, Section 4(b)
above shall control, and not this subsection on termination for Cause.

<PAGE>

(e) By Employee Not for Cause. At any time, King may terminate his employment
for any reason, with or without cause, by providing SPDV thirty (30) days'
advance written notice. SPDV shall have the option, in its complete discretion,
to make King's termination effective at any time prior to the end of such notice
period, provided SPDV pays and delivers to King all compensation, including
stock earned under Section 3, due and owing through the last day actually
worked, plus an amount equal to the base salary King would have earned through
the balance of the above notice period, not to exceed thirty (30) days;
thereafter, all of SPDV's obligations under this Agreement shall cease.

(f) By Employee for Good Reason. King may terminate, without liability, the
Period of Employment for Good Reason (as defined below), provided King gives
SPDV thirty (30) days' advance written notice of the reason for termination and
his intent to terminate this Agreement. So long as the reason is not SPDV's
failure to pay the salary due under subsection 3 (a) above or failure to issue
the stock pursuant to subsection 3(b) above. SPDV shall have an opportunity
during the 30 day notice period to correct the condition constituting Good
Reason. If the condition is remedied within this period, King's notice to
terminate shall be rescinded automatically; if not remedied, termination shall
become effective upon expiration of the above notice period. King shall have the
right to terminate this agreement with 48 hours notice to SPDV in the event SPDV
fails to pay the consideration due under subsections 3(a) or 3(b) above. In any
event of termination under this subsection SPDV shall pay King all compensation
due and owing through the last day actually worked, plus a lump-sum severance
payment equal to one (1) month base salary, which payments shall be in lieu of
any damages under this Agreement for any alleged breach. The parties agree that
at the time of the making of this agreement the damages which King may suffer as
a result of the Good Reason not being cured by SPDV are speculative, unknown and
difficult or impossible to determine. They agree at this time the one months
severance pay is a reasonable estimate at the time this contract is made to
compensate King as Liquidated Damages for all damages which King would suffer as
a result of a breach of this agreement. After making such payment of one months
severance pay, all of SPDV's obligations under this Agreement, and all payment
obligations of the Company shall cease. SPDV shall also have the option, in its
complete discretion, to make King's termination effective at any time prior to
the end of the notice period, provided that SPDV pays King all compensation due
and owing through the balance of the notice period (not to exceed thirty (30)
days), in addition to the payment of six (6) months' then current base salary.
King shall be entitled to exercise his right to terminate this Agreement for
Good Reason only if he gives the required notice not more than ten (10) days
after the occurrence of the event that is the basis for the Good Reason.

Termination shall be for "Good Reason" if: (1) there is a material and adverse
change in King's position, duties, responsibilities, or status with SPDV; (2)
there is a reduction in King's salary then in effect, other than a reduction
comparable to reductions generally applicable to similarly situated employees of

<PAGE>

SPDV; (3) there is a material reduction in King's benefits, other than a
reduction comparable to reductions generally applicable to similarly situated
employees of SPDV; or (4) SPDV materially breaches this Agreement. King shall
not be entitled to terminate this Agreement for Good Reason if an event occurs
that would otherwise constitute Good Reason, except that it results from a
change in SPDV's status as defined in Section 4(g).

(g) Change in Employer Status. To the extent permitted by law, SPDV, in its sole
discretion, may terminate the Period of Employment (in which case all of SPDV's
obligations under this Agreement shall cease after payment of all compensation
due and owing) upon any formal action of SPDV's management to terminate SPDV's
existence or otherwise wind up its affairs, to sell all or substantially all of
its assets, or to merge with or into another entity.

(h)  Termination Obligations.

         (1) King agrees that all property, including, without limitation, all

fully cooperate with SPDV in all matters relating to the winding up of pending
work on behalf of SPDV and the orderly transfer of work to other employees of

                  services to SPDV, which are protected by a separate
                  non-disclosure agreement, currently in effect.

         c)       Any information received by King without any wrong doing from
                  someone outside the Company who obtained that information in a
                  lawful manner and who does not have any obligation to keep the
                  information confidential or proprietary.

(b) General Restrictions on Use. During the Period of Employment, King shall use
Proprietary Information, and shall disclose Proprietary Information, only for
the benefit of SPDV and as is necessary to carry out his responsibilities under
this Agreement. Following termination, King shall neither, directly or
indirectly, use any Proprietary Information nor disclose any Proprietary
Information, except as expressly and specifically authorized in writing by SPDV
for a period of three years after termination. The publication of any
Proprietary Information through literature or speeches must be approved in
advance in writing by SPDV.

(c) Location and Reproduction. King shall maintain at his work station and/or
any other place under his control only such Proprietary Information as he has a
current "need to know." King shall return to the appropriate person or location
or otherwise properly dispose of Proprietary Information once that need to know
no longer exists. King shall not make copies of or otherwise reproduce

<PAGE>

Proprietary Information unless there is a legitimate business need for
reproduction.

(d) Prior Actions and Knowledge. King represents and warrants that from the time
of his first contact with SPDV, he has held in strict confidence all Proprietary
Information and has not disclosed any Proprietary Information, directly or
indirectly, to anyone outside of SPDV, or used, copied, published, or summarized
any Proprietary Information, except to the extent otherwise permitted in this
Agreement.

(e) Third-Party Information. King acknowledges that SPDV has received and in the
future will receive from third parties their Proprietary information subject to
a duty on SPDV's part to maintain the confidentiality of such information and to
use it only for certain limited purposes. King agrees that he owes SPDV and such
third parties, during the Period of Employment and thereafter, a duty to hold
all such Proprietary information in the strictest confidence and not to disclose
or use it except as necessary to perform his obligations hereunder and as is
consistent with SPDV's agreement with such third parties.

(f) Competitive Activity. King acknowledges that the pursuit of the activities
forbidden by this subsection would necessarily involve the use or disclosure of
Proprietary Information in breach of the preceding subsections, but that proof
of such a breach would be extremely difficult. To forestall such disclosure,
use, and breach, and in consideration of the employment under this Agreement,
King agrees that for a period of one (1) year after termination of the Period of
Employment, he shall not, directly or indirectly, (1) divert or attempt to
divert from SPDV (or any Affiliate) any business of any kind in which it is
engaged, including, without limitation, the solicitation of or interference with
any of its customers; (2) employ or solicit for employment any person currently
employed by SPDV (or any subsidiary of SPDV); or (3) engage in any business
activity that is or may be competitive with SPDV (or any subsidiary of SPDV) in
any state where SPDV conducts its business, unless King can prove that any
action taken in contravention of this subsection was done without the use in any
way of Proprietary Information.

6.  Inventions and Ideas.

(a) Defined; Statutory Notice. The term "Invention/Idea" includes any and all
ideas, processes, trademarks, service marks, inventions, technology, computer
hardware or software, original works of authorship, designs, formulas,
discoveries, patents, copyrights, products, and all improvements, know-how,
rights, and claims related to the foregoing, that are conceived, developed, or
reduced to practice by King (alone or with others), during the Period of
Employment, except to the extent that California Labor Code Section 2870
lawfully prohibits the assignment of rights in such intellectual property.

<PAGE>

King acknowledges that he understands that this definition includes only those
rights that may be lawfully assigned pursuant to California Labor Code Section
2870, which provides:

    "(a) Any provision in an employment agreement which provides that an
employee shall assign, or offer to assign, any of his or her rights in an
invention to his or her employer shall not apply to an invention that the
employee developed entirely on his or her own time without using the employer's
equipment, supplies, facilities, or trade secret information except for those
inventions that either:

          (1) Relate at the time of conception or reduction to practice of the
invention to the employer's business, or actual or demonstrably anticipated
research or development of the employer; or

          (2) Result from any work performed by the employee for the employer.

(b) To the extent a provision in an employment agreement purports to require an
employee to assign an invention otherwise excluded from being required to be
assigned under subdivision (a), the provision is against the public policy of
this state and is unenforceable."

Nothing in this Agreement is intended to expand the scope of protection provided
King by Sections 2870 through 2872 of the California Labor Code.

(c) Disclosure. King agrees to maintain adequate and current written records on
the development of all Invention/Ideas and to disclose promptly to SPDV all
Invention/Ideas and relevant records, which records will remain the sole
property of SPDV. King further agrees that all information and records
pertaining to any ideas, processes, trademarks, service marks, inventions,
technology, computer hardware or software, original works of authorship,
designs, formulas, discoveries, patents, copyrights, products, and all
improvements, know-how, rights, and claims related to the foregoing
("Intellectual Property"), that King does not believe to be an Invention/Idea,
but that is conceived, developed, or reduced to practice by King (alone or with
others) during the Period of Employment (or during the post-employment period
set forth in Section 6(e) below), shall be disclosed promptly to SPDV (such
disclosure to be received in confidence). SPDV shall examine such information to
determine if in fact the Intellectual Property is an Invention/Idea subject to
this Agreement.

(d) Assignment. King agrees to assign to SPDV his entire right, title, and
interest (throughout the United States and in all foreign countries), free and
clear of all liens and encumbrances, in and to each Invention/Idea, which shall
be the sole property of SPDV, whether or not patentable. In the event any
Invention/Idea is deemed by SPDV to be patentable or otherwise registrable, King
shall assist SPDV (at its expense) in obtaining letters patent or other
applicable registrations thereon and shall execute all documents and do all
other things necessary or proper thereto (including testifying at SPDV's

<PAGE>

expense) and to vest SPDV, or any entity or person specified by SPDV, with full
and perfect title thereto or interest therein. At SPDV's expense, King shall
also take any action necessary or advisable in connection with any
continuations, renewals, or reissues thereof or in any related proceedings or
litigation. Should SPDV be unable to secure King's signature on any document
necessary to apply for, prosecute, obtain, or enforce any patent, copyright, or
other right or protection relating to any Invention/Idea, whether due to King's
mental or physical incapacity or any other cause, King irrevocably designates
and appoints SPDV and each of its duly authorized officers and agents as King's
agent and attorney in fact, to act for and in King's behalf and stead and to
execute and file any such document, and to do all other lawfully permitted acts
to further the prosecution, issuance, and enforcement of patents, copyrights, or
other rights or protections with the same force and effect as if executed,
delivered, and/or done by King.

(e) Exclusions. Except as described in Exhibit A1 attached to this Agreement, to
the best of King's knowledge, there is no existing contract in conflict with
this Agreement and there is no contract to assign any Intellectual Property that
is now in existence between King and any other person or entity.

(f) Post-Termination Period. Because of the difficulty of establishing when any
Intellectual Property is first conceived or developed by King, or whether it
results from access to Proprietary Information or SPDV's equipment, supplies,
facilities, or data, King agrees that any Intellectual Property shall be
presumed to be an Invention/Idea, if reduced to practice by King or with the aid
of King within one (1) year after termination of the Period of Employment. King
can rebut the above presumption if he proves that the Intellectual Property (1)
was developed entirely on King's own time without using SPDV's equipment,
supplies, facilities, or trade secret information; (2) was not conceived or
reduced to practice during the Period of Employment, or, if conceived or reduced
to practice during this period, did not, at the time of conception or reduction
to practice, relate to SPDV's business or actual or demonstrably anticipated
research or development; and (iii) did not result from any work performed by
King for SPDV.

7.  Arbitration.

(a) Arbitrable Claims. Disputes between King (and his attorneys, successors, and
assigns) and SPDV (and its Affiliates, shareholders, directors, officers,
employees, agents, successors, attorneys, and assigns) relating in any manner
whatsoever to the employment or termination of King, with the exception of a
breach by King of any responsibility under Section 5, 6 or 15 of this agreement,
but including, without limitation, all disputes regarding the duties of the
parties arising under this Agreement, ("Arbitrable Claims") shall be resolved by
arbitration. All persons and entities specified in the preceding sentence (other

- ---------------
1     Exhibit A is included as a separate document, forwarded with these
modifications to the Employment Agreement

<PAGE>

than SPDV and King) shall be considered third-party beneficiaries of the rights
and obligations created by this Section on Arbitration. Arbitrable Claims shall
include, but are not limited to, contract (express or implied) and tort claims
of all kinds, as well as all claims based on any federal, state, or local law,
statute, or regulation, excepting only claims under applicable workers'
compensation law and unemployment insurance claims. Arbitration shall be final
and binding upon the parties and shall be the exclusive remedy for all
Arbitrable Claims, except that SPDV may, at its option, seek injunctive relief
and damages in court of law or equity for any breach of Sections 5 and 6, or
under the provisions of Section 15 of this Agreement. Subject to the foregoing
sentence, THE PARTIES HEREBY WAIVE ANY RIGHTS THEY MAY HAVE TO TRIAL BY JURY IN
REGARD TO ARBITRABLE CLAIMS.

(b) Procedure. Arbitration of Arbitrable Claims shall be in accordance with the
Employment Dispute Resolution Rules of the American Arbitration Association
("AAA Employment Rules"), except as provided otherwise in this Agreement. Prior
to resorting to arbitration, the complaining party must first exhaust the
procedures specified in any SPDV Employment Manual. Arbitration shall be
initiated by providing written notice to the other party with a statement of the
claim(s) asserted, the facts upon which the claim(s) are based, and the remedy
sought. This notice shall be provided to the other party within six (6) months
of the acts or omissions complained of. Any claim not initiated within this
limitation period shall be null and void. EACH PARTY WAIVES ALL RIGHTS UNDER
STATUTES OF LIMITATIONS OF DIFFERENT DURATION. In any arbitration, the burden of
proof shall be allocated as provided by applicable law. Either party may bring
an action in court to compel arbitration under this Agreement and to enforce an
arbitration award. Otherwise, neither party shall initiate or prosecute any
lawsuit or administrative action in any way related to any Arbitrable Claim. All
arbitration hearings under this Agreement shall be conducted in San Diego,
California. The provisions of California Code of Civil Procedure section 1280
et. seq. shall govern the interpretation and enforcement of this Section 7.

(c) Arbitrator Selection and Authority. All disputes involving Arbitrable Claims
shall be decided by a single arbitrator. The arbitrator shall be selected by
mutual agreement of the parties within thirty (30) days of the effective date of
the notice initiating the arbitration. If the parties cannot agree on an
arbitrator, then the complaining party shall notify the AAA and request
selection of an arbitrator in accordance with the AAA Employment Rules. The
arbitrator shall have the authority to award equitable relief, damages, costs,
and fees as provided by law for the particular claim(s) asserted. The fees of
the arbitrator shall be split between both parties equally. The arbitrator shall
have exclusive authority to resolve all Arbitrable Claims, including, but not
limited to, any claim that all or any part of this Agreement is void or
unenforceable.

(d) Confidentiality. All proceedings and all documents prepared in connection
with any Arbitrable Claim shall be confidential and, unless otherwise required
by law, the subject matter thereof shall not be disclosed to any person other

<PAGE>

than the parties to the proceedings, their counsel, witnesses and experts, the
arbitrator, and, if involved, the court and court staff. All documents filed
with the arbitrator or with a court shall be filed under seal. The parties shall
stipulate to all arbitration and court orders necessary to effectuate fully the
provisions of this subsection concerning confidentiality.

(e) Continuing Obligations. The rights and obligations of King and SPDV set
forth in this Section on Arbitration shall survive the termination of King's
employment and the expiration of this Agreement.

8. Notices. Any notice under this Agreement must be in writing and shall be
effective upon delivery by hand, upon facsimile transmission to the number
provided below (if one is provided), or three (3) business days after deposit in
the United States mails, postage prepaid, certified or registered, and addressed
to SPDV or to King at the corresponding address below. King shall be obligated
to notify SPDV in writing of any change in his address. Notice of change of
address shall be effective only when done in accordance with this Section.

                  SPDV's Notice Address:

                  SpaceDev Inc.
                  Attn: President

                  San Diego, California 92126

                  King's Notice Address:

                  Jan A. King
                  8444 Capricorn Way, Apt. 69
                  San Diego, California 92126

9. Action by SPDV. All actions required or permitted to be taken under this
Agreement by SPDV, including, without limitation, exercise of discretion,
consents, waivers, and amendments to this Agreement, shall be made and
authorized only by the President or by his or her representative specifically
authorized to fulfill these obligations under this Agreement.

10. Integration. This Agreement is intended to be the final, complete, and
exclusive statement of the terms of King's employment by SPDV. This Agreement
may not be contradicted by evidence of any prior or contemporaneous statements
or agreements. To the extent that the practices, policies, or procedures of
SPDV, now or in the future, apply to King and are inconsistent with the terms of
this Agreement, the provisions of this Agreement shall control.

11. Amendments; Waivers. This Agreement may not be modified, amended, or
terminated except by an instrument in writing, signed by each of the parties. No

<PAGE>

failure to exercise and no delay in exercising any right, remedy, or power under
this Agreement shall operate as a waiver thereof, nor shall any single or
partial exercise of any right, remedy, or power under this Agreement preclude
any other or further exercise thereof, or the exercise of any other right,
remedy, or power provided herein or by law or in equity.

12. Assignment; Successors and Assigns. King agrees that he will not assign,
sell, transfer, delegate, or otherwise dispose of, whether voluntarily or
involuntarily, or by operation of law, any rights or obligations under this
Agreement. Any such purported assignment, transfer, or delegation shall be null
and void. Nothing in this Agreement shall prevent the consolidation of SPDV
with, or its merger into, any other entity, or the sale by SPDV of all or
substantially all of its assets, or the otherwise lawful assignment by SPDV of
any rights or obligations under this Agreement. Subject to the foregoing, this
Agreement shall be binding upon and shall inure to the benefit of the parties
and their respective heirs, legal representatives, successors, and permitted
assigns, and shall not benefit any person or entity other than those
specifically enumerated in this Agreement.

13. Severability. If any provision of this Agreement, or its application to any
person, place, or circumstance, is held by an arbitrator or a court of competent
jurisdiction to be invalid, unenforceable, or void, such provision shall be
enforced to the greatest extent permitted by law, and the remainder of this
Agreement and such provision as applied to other persons, places, and
circumstances shall remain in full force and effect.

14. Attorneys' Fees. In any legal action, arbitration, or other proceeding
brought to enforce or interpret the terms of this Agreement, the prevailing
party shall be entitled to recover reasonable attorneys' fees and costs and the
fees and costs of any arbitration itself.

15. Injunctive Relief. If (1) King refuses to perform the responsibilities
outlined in Section 2 on Position and Responsibilities within the agreed upon
Period of Employment, and King has no right to terminate the employment
relationship pursuant to Section 4 on Termination of Employment, or (2) King
breaches or threatens to breach any of the covenants in Section 5 on Proprietary
Information and Section 6 on Inventions and Ideas, the parties acknowledge that
the damage or imminent damage to SPDV's business or its goodwill would be
irreparable and extremely difficult to estimate, making any remedy at law or in
damages inadequate. Accordingly, SPDV shall be entitled to injunctive relief or
other equitable remedy provided by a court of equity against King in the event
of any breach or threatened breach of such provisions by King, in addition to
any other relief (including damages) available to SPDV under this Agreement or
under law.

16. Governing Law. This Agreement shall be governed by and construed in
accordance with the law of the State of California. Venue for any dispute shall
be in San Diego County California.

<PAGE>

17. Interpretation. This Agreement shall be construed as a whole, according to
its fair meaning, and not in favor of or against any party. By way of example
and not in limitation, this Agreement shall not be construed in favor of the
party receiving a benefit nor against the party responsible for any particular
language in this Agreement.

18. Employee Acknowledgment. King acknowledges that he has had the opportunity
to consult legal counsel in regard to this Agreement, that he has read and
understands this Agreement, that he is fully aware of its legal effect
(including notice of his statutory rights under Section 2870 of the California
Labor Code, as set forth in the above Section on Inventions and Ideas), and that
he has entered into it freely and voluntarily and based on his own judgment and
not on any representations or promises other than those contained in this
Agreement.

The parties have duly executed this Agreement as of the date first written
above.

                                    EXHIBIT A

               PATENTS/INVENTIONS AND OTHER INTELLECTUAL PROPERTY
                                 OF JAN A. KING
                       EXCLUDED FROM EMPLOYMENT AGREEMENT

The following are patents or inventions not patented, but reduced to practice
and works authored by me that I consider excluded from my SpaceDev employment
agreement:

 Method and Apparatus for Deploying a Satellite Network, U.S. Patent 5199672,
     dated April 6, 1993.  NOTE: This patent has been fully assigned to Orbital
     Sciences Corp. of Dulles, VA.

Development of the Microsat Spacecraft Concept. A technology developed jointly
     by me and the Radio Amateur Satellite Corp. (AMSAT). This technology has
     been reduced to practice in 1989 and has been contributed by me to AMSAT,
     however, the rights to the technology remain with me and others who
     developed the technology. The technology is being held as a trade secret.
     AMSAT has sub licensed the technology to industry and to non-profit
     organizations.

M/N Series Resonant Orbits. A body of knowledge developed in a series of papers
     written by me. The papers describe the properties of a family of orbits
     most suitable when used for communications and certain remote sensing
     satellites.

Inverse Pseudolite Position Determination. A method of using a GPS Pseudolite in
     a reverse roll as a means of tracking lost or stolen objects. The technique
     uses the GPS constellation and sites similar to cellular radio base
     stations to locate a TAG carrying a pseudolite transmitter. The transmitter
     transmits a CDMA code identical to that of the GPS constellation (C/A
     only). The technique was invented by myself, Michael Carpenter and Gordon
     Hardman. The invention is currently being held as a trade secret. A similar
     technique seems to have been developed by the United States Air Force and
     the University of Vancouver, B.C.. A patent may or may not be filed by the
     inventors based on whether we can claim the invention.

Alternative Method of Spectrum Allocation and Assignment Coupled with a Spectrum
     Use Measurement System. This is a method of assigning users of the radio
     spectrum to channels, based on priority and demand and not based on the
     category of service concept (as is currently done). The technique is
     intended to capitalize on various changes taking place in
     telecommunications today, on a national and global basis. These include the
     increasing utilization of Spread Spectrum technology (CDMA) and the
     practice of "selling" radio spectrum to certain categories of users. In
     order to make such a scheme practical, a land/air/space based monitoring
     system would be utilized. This approach to monitoring the use of the radio
     spectrum would avoid spectrum "warehousing" and illegal usage of frequency
     bands. Both practices are common today. This technique was developed by Mr.
     Gordon Hardman, Mr. Bruce Ferguson and myself and is being kept as a trade
     secret at this time.

         This Employment Agreement (the "Agreement"), dated as of November 2,
1999, is between Integrated Space Systems, Inc. (referred to as the "Company" or
"ISS") a wholly owned subsidiary of SpaceDev, Inc., a Colorado corporation, and
Charles H. Lloyd ("Executive").

                                    RECITALS

         WHEREAS, Executive has the experience to provide services to Company of
an extraordinary character which gives such services a unique value, the loss of
which cannot be reasonably or adequately compensated in damages in an action at
law.

         WHEREAS, Company desires to retain the services of Executive, and
Executive desires to be employed by Company for the term of this Agreement.

         NOW AND THEREFORE, in consideration of the mutual representation and
covenants, the parties agree as follows:

1.       PERIOD OF EMPLOYMENT.

         BASIC TERM. Company shall employ Executive to render services to
Company in the position and with the duties and responsibilities described in
Section 2 for the period (the "Period of Employment") commencing on the date of
this Agreement and ending upon the date of termination in accordance with
Section 4.

2.       POSITION AND RESPONSIBILITIES.

         (a) POSITION. Executive accepts employment with Company as Chief
Executive Officer and shall perform all services appropriate and related to
raising equity financing for ISS, overseeing the development of the Micro Launch
Vehicle, preparing ISS for an Initial Public Offering, and as such other
services as may be assigned by Company. Executive shall devote his best efforts
and full-time attention to the performance of his duties. Executive shall be
subject to the direction of Company, which shall retain full control of the
means and methods by which he performs the above services and of the place(s) at
which all services are rendered. Executive shall report to the Chairman of the
Board of Directors of Company. Executive shall be expected to travel if
necessary or advisable in order to meet the obligations of his position.

         (b) OTHER ACTIVITY. Except upon the prior written consent of
Company, Executive (during the Period of Employment) shall not (i) accept any
other employment; or (ii) engage, directly or indirectly, in any other business,
commercial, or professional activity (whether or not pursued for pecuniary
advantage) that is or may be competitive with Company, that might create a
conflict of interest with Company, or that otherwise might interfere with the
business of Company, or any Affiliate. An "Affiliate" shall mean any person or
entity that directly or indirectly controls, is controlled by, or is under
common control with Company. So that Company may be aware of the extent of any
other demands upon Executive's time and attention, Executive shall disclose in
confidence to Company the nature and scope of any other business activity in
which he is or becomes engaged during the Period of Employment.

                                       1
<PAGE>

         (c) REPRESENTATIONS. Executive represents and warrants (i) that he
is fully qualified and competent to perform the responsibilities for which he is
being hired pursuant to the terms of this Agreement; and (ii) that Executive's
execution of this Agreement, his employment with Company, and the performance of
his proposed duties under this Agreement shall not violate any obligations he
may have to any former employer (or other person or entity), including any
obligations with respect to proprietary or confidential information of any other
person or entity.

         (d) INDEMNIFICATION. Executive agrees to indemnify Company, its
officers, directors and affiliates for all cost and expenses including out of

3.       COMPENSATION AND BENEFITS.

         (a) COMPENSATION. In consideration of the services to be rendered
under this Agreement, Company shall pay Executive a base salary of Sixty
Thousand Dollars ($60,000) for the first twelve (12) months of this Agreement,
payable pursuant to the Company's established payroll procedures, and as may be
amended, by Company in its sole discretion, during the Period of Employment. In
the event this Agreement is in effect beginning the first anniversary date of
this Agreement, Company shall pay executive a base salary of Two Hundred
Thousand Dollars ($200,000) per year. Thereafter Company shall review annually
Executive's compensation in accordance with Company's established administrative
practice for adjusting salaries for similarly situated employees.

         (b) STOCK OPTIONS OR CASH BONUS. As additional consideration for
the services to be rendered under this Agreement and to provide Executive with
additional incentive to raise equity financing for the Company, Executive may
elect either of the following two methods:

                  (i)      SpaceDev shall provide stock options to Executive
                           upon the execution of this Agreement in the amount
                           not to exceed 200,000 common shares of SpaceDev with
                           an exercise price equal to the value at the date of
                           grant and subject to forfeiture and vesting. The
                           stock options shall vest upon the Company raising and
                           acquiring a minimum equity financing of Three Million
                           Dollars with a maxim equity financing of Ten Million
                           Dollars ($10,000,000) within the first nine (9)
                           months of Executive's employment. For each One
                           Million Dollars ($1,000,000) in equity financing
                           obtained by the Company, Executive's stock options
                           representing 20,000 common shares of Space will vest
                           and shall not be subject to forfeiture. In the event,
                           the Company does not receive any funds or receives
                           funds less than the Three Million Dollars within the
                           first nine months of Executive's employment, then
                           that portion of stock options which have not vested,
                           shall be immediately forfeited and cancelled. OR

                           percent (2%) of the equity financing acquired by the
                           Company within the first nine months of Executive
                           employment. Cash bonus payment, which shall not
                           exceed $200,000, shall be paid to Executive when
                           Company receives funds in excess of Three Millions
                           Dollars ($3,000,000). In the event, the Company does
                           not receive any funds or receives funds less than the
                           Three Million Dollars within the first nine months of
                           Executive's employment, then no cash bonus shall

         The stock options issued to Executive under this section shall be
subject to the terms and conditions of the Plan. Executive acknowledges that he
has received and had an opportunity to review the Plan.

         (d) BENEFITS. Executive shall be entitled to vacation leave in
accordance with Company's standard policies. As Executive becomes eligible
therefor, Executive shall have the right to participate in and to receive
benefits from all present and future benefit plans specified in Company's
policies and generally made available to similarly situated employees of
Company. The amount and extent of benefits to which Executive is entitled shall
be governed by the specific benefit plan, as amended. Executive also shall be
entitled to any benefits or compensation tied to termination as described in
Section 4. Nothing stated in this Agreement shall prevent Company from changing
or eliminating any benefit during the Period of Employment as Company, in its
sole discretion, may deem necessary or desirable. No statement concerning
benefits or compensation to which Executive is entitled shall alter in any way
the term of this Agreement, any renewal thereof, or its termination. All
compensation and comparable payments to be paid to Executive under this
Agreement shall be less withholdings required by law.

         (e) EXPENSES. Company shall reimburse Executive for reasonable travel
and other business expenses incurred by Executive in the performance of his
duties, in accordance with Company's policies, as they may be amended in
Company's sole discretion.

4.       TERMINATION OF EMPLOYMENT.

         (a) BY DEATH. The Period of Employment shall terminate automatically
upon the death of Executive. Company shall pay to Executive's beneficiaries or
estate, as appropriate, any compensation and benefits then due and owing,
including payment for accrued unused vacation, if any. Thereafter, all
obligations of Company under this Agreement shall cease. Nothing in this Section
shall affect any entitlement of Executive's heirs to the benefits of any life
insurance plan or other applicable benefits.

                                       3
<PAGE>

         (b) BY DISABILITY. If, by reason of any physical or mental incapacity,
Executive has been or will be prevented from properly performing his duties
under this Agreement for more than ninety (90) days in any one (1) year period,
then, to the extent permitted by law, Company may terminate the Period of
Employment upon two (2) weeks' advance written notice. Company shall pay
Executive all compensation to which he is entitled up through the last business
day of the notice period; thereafter, all obligations of Company under this
Agreement shall cease. Nothing in this Section shall affect Executive's rights
under any applicable Company disability plan.

         (c) BY EMPLOYER NOT FOR CAUSE. At any time, Company may terminate
Executive for any reason, with or without cause, by providing Executive sixty
(60) days written notice. Company shall have the option, in its complete
discretion, to terminate Executive at any time prior to the end of such notice
period, provided Company pays Executive all compensation and benefits due and
owing through the above notice period. In the event this Agreement is in effect
after Executive's one year anniversary, then in addition to the compensation and
benefits due and owing, Company shall pay Executive a severance in the amount of
Eight Thousand Dollars ($8,000) per month payable over a twelve month period;
Upon termination, all of Company's obligations under this Agreement shall cease.
Company may dismiss Executive without cause notwithstanding anything to the
contrary contained in or arising from any statements, policies, or practices of
Company relating to the employment, discipline, or termination of its employees.

         (d) BY EMPLOYER FOR CAUSE. At any time, and without prior notice,
Company may terminate Executive for Cause (as defined below). Company shall pay
Executive all compensation then due and owing; thereafter, all of Company's
obligations under this Agreement shall cease. Termination shall be for "Cause"
if Executive: (i) acts in bad faith and to the detriment of Company; (ii)
refuses or fails to act in accordance with any specific direction or order of
Company; (iii) exhibits in regard to his employment unfitness or unavailability
for service, unsatisfactory performance, misconduct, dishonesty, habitual
neglect, or incompetence; (iv) is convicted of a crime involving dishonesty,
breach of trust, or physical or emotional harm to any person; (v) is selected
for layoff pursuant to a bona fide reduction in force; or (vi) breaches any
material term of this Agreement. If termination is due to Executive's
disability, Section 4(b) above shall control, and not this subsection on
termination for Cause.

         (e) BY EMPLOYEE NOT FOR CAUSE. At any time, Executive may terminate his
employment for any reason, with or without cause, by providing Company thirty
(30) days' written notice. Company shall have the option, in its complete
discretion, to make Executive's termination effective at any time prior to the
end of such notice period, provided Company pays Executive all compensation due
and owing through the last day actually worked, plus an amount equal to the base
salary Executive would have earned through the balance of the above notice
period, not to exceed thirty (30) days; thereafter, all of Company's obligations
under this Agreement shall cease.

                                       4
<PAGE>

         (f) BY EMPLOYEE FOR GOOD REASON. Executive may terminate, without
liability, the Period of Employment for Good Reason (as defined below), provided
Executive gives Company thirty (30) days' advance written notice of the reason
for termination and his intent to terminate this Agreement. During this period,
Company shall have an opportunity to correct the condition constituting Good
Reason. If the condition is remedied within this period, Executive's notice to
terminate shall be rescinded automatically; if not remedied, termination shall
become effective upon expiration of the above notice period. In this event,
Company shall pay Executive all compensation due and owing through the last day
actually worked, plus a lump-sum payment equal to six (6) months' base salary,
which payments shall be in lieu of any damages under this Agreement for any
alleged breach. Thereafter, all of Company's obligations under this Agreement
shall cease. Company shall also have the option, in its complete discretion, to
make Executive's termination effective at any time prior to the end of the
notice period, provided that Company pays Executive all compensation due and
owing through the balance of the notice period (not to exceed thirty (30) days),
in addition to the payment of six (6) months' base salary described above.
Executive shall be entitled to exercise his right to terminate this Agreement
for Good Reason only if he gives the required notice not more than forty-five
(45) days after the occurrence of the event that is the basis for the Good
Reason.

         Termination shall be for "Good Reason" if: (i) there is a material and
adverse change in Executive's position, duties, responsibilities, or status with
Company; (ii) there is a reduction in Executive's salary then in effect, other
than a reduction comparable to reductions generally applicable to similarly
situated employees of Company; (iii) there is a material reduction in
Executive's benefits, other than a reduction comparable to reductions generally
applicable to similarly situated employees of Company; or (iv) Company
materially breaches this Agreement. Executive shall not be entitled to terminate
this Agreement for Good Reason if an event occurs that would otherwise
constitute Good Reason, except that it results from a change in Company's status
as defined in Section 4(g).

         (g) CHANGE IN EMPLOYER STATUS. To the extent permitted by law, Company,
in its sole discretion, may terminate this Agreement (in which case all of
Company's obligations under this Agreement shall cease after payment of all
compensation due and owing) upon any formal action of Company's management to
terminate Company's existence or otherwise wind up its affairs, to sell all or
substantially all of its assets, or to merge with or into another entity.

         (h) TERMINATION OBLIGATIONS.

                  (i) Executive agrees that all property, including, without
         limitation, all equipment, tangible Proprietary Information (as defined
         below), documents, books, records, reports, notes, contracts, lists,
         computer disks (and other computer-generated files and data), and
         copies thereof, created on any medium and furnished to, obtained by, or
         prepared by Executive in the course of or incident to his employment,
         belongs to Company and shall be returned promptly to Company upon
         termination of the Period of Employment.

                  (ii) All benefits to which Executive is otherwise entitled
         shall cease upon Executive's termination, unless explicitly continued
         either under this Agreement or under any specific written policy or
         benefit plan of Company.

                                       5
<PAGE>

                  (iii) Upon termination of the Period of Employment, Executive
         shall be deemed to have resigned from all offices and directorships
         then held with Company or any Affiliate.

                  (iv) The representations, indemnification and warranties
         contained in this Agreement shall survive the termination of the Period
         of Employment and the expiration of this Agreement.

                  (v) Following any termination of the Period of Employment,
         Executive shall fully cooperate with Company in all matters relating to
         the winding up of pending work on behalf of Company and the orderly
         transfer of work to other employees of Company. Executive shall also
         cooperate in the defense of any action brought by any third party
         against Company that relates in any way to Executive's acts or
         omissions while employed by Company.

5.       PROPRIETARY INFORMATION.

         (a) DEFINED. "Proprietary Information" is all information and any idea
in whatever form, tangible or intangible, pertaining in any manner to the
business of Company, or any Affiliate, or its employees, clients, consultants,
or business associates, which was produced by any employee of Company in the
course of his or her employment or otherwise produced or acquired by or on
behalf of Company. All Proprietary Information not generally known outside of
Company's organization, and all Proprietary Information so known only through
improper means, shall be deemed "Confidential Information." Without limiting the
foregoing definition, Proprietary Information and Confidential Information shall
include, but not be limited to: (i) teaching and development techniques,
processes, confidential or secret designs, and trade secrets; (ii) information
about costs, profits, markets, sales, and lists of customers or clients; (iii)
business, marketing, and strategic plans; (iv) employee personnel files and
compensation information; and (v) research, systems, protocols, programs, plans,
and devices and software. Executive should consult any Company procedures
instituted to identify and protect certain types of Confidential Information,
which are considered by Company to be safeguards in addition to the protection
provided by this Agreement. Nothing contained in those procedures or in this
Agreement is intended to limit the effect of the other.

         (b) CONFIDENTIALITY. Executive will not disclose any Proprietary
Information to any third party for any reason whatsoever. Executive will not
disclose any Proprietary Information to any person unless that person is a
director, officer, Executive, advisor or representative of Company who needs
such information for the purpose of evaluating any possible transaction (it
being understood that those directors, officers, employees, advisors and
representatives shall be informed by Executive of the confidential nature of the
Proprietary Information and shall be directed by Executive to treat such
information confidentially). In any event, no Proprietary Information shall be
disclosed without the prior written consent of Company. Executive will not
utilize any Proprietary Information he receives for the benefit of anyone other
than Company. Executive will promptly and fully disclose to Company the name of
any person receiving any Proprietary Information of Company. This Section
5(b)shall survive the termination of employment and Executive agrees that this
agreement shall remain in full force and effect for a period of one (1) year
after termination of employment with Company. In the event of a breach of this
Section 5(b), Executive acknowledges that, in addition to any other damages,
Company reserves the right to seek injunctive relief in a court of equity
against Executive, and/or any other parties to prevent further breaches from
occurring and/or minimize Company's damages due to a breach subsequent to the
time Company discovers the breach has occurred. Nothing in this Section 5(b)
shall be construed to constitute the grant of a license to Executive under any
trademark, patent, patent application, or Proprietary Information.

                                       6
<PAGE>

         (c) COMPETITIVE ACTIVITY. Executive acknowledges that the pursuit of
the activities forbidden by this section would necessarily involve the use or
disclosure of Confidential Information in breach of the preceding subsections,
but that proof of such a breach would be extremely difficult. To forestall such
disclosure, use, and breach, and in consideration of the employment under this
Agreement, Executive agrees that for a period of one (1) year after termination
of the Period of Employment, he shall not, directly or indirectly, (i) divert or
attempt to divert from Company (or any Affiliate) any business of any kind in
which it is engaged, including, without limitation, the solicitation of or
interference with any of its customers; (ii) employ, solicit for employment, or
recommend for employment any person employed by Company (or any Affiliate); or
(iii) engage in any business activity that is or may be competitive with Company
(or any Affiliate) in any state where Company conducts its business, unless
Executive can prove that any action taken in contravention of this subsection
was done without the use in any way of Confidential Information.

         (d) COMPANY MANUAL. Employee acknowledges that he has received a copy
of the SpaceDev Employee Manual ("Manual") and has read and agrees to comply
with the terms and conditions contained in the Manual. Employee further
understands that violation of any provision of the Manual shall be cause for
immediate termination of this Agreement and constitute "For Cause" as described
in section 4 (d) above


6.       PRIOR KNOWLEDGE AND INFORMATION.

         Executive acknowledges that he may have certain proprietary information
that was obtained during the course of his former employment or business
dealings with other third parties. Executive agrees and represents that he will
not use or disclose, and that Company has not requested that Executive use or
disclose, any third party proprietary information which would be in violation of
any laws. Furthermore, Executive agrees to indemnify Company for the cost,
expenses and loss related to any action or claim arising from the
misappropriation of proprietary information of third parties.

7.       ARBITRATION.

         (a) ARBITRABLE CLAIMS. All disputes between Executive (and his
attorneys, successors, and assigns) and Company (and its Affiliates,
shareholders, directors, officers, employees, agents, successors, attorneys, and
assigns) relating in any manner whatsoever to the employment or termination of
Executive, including, without limitation, all disputes arising under this
Agreement, ("Arbitrable Claims") shall be resolved by arbitration. All persons
and entities specified in the preceding sentence (other than Company and
Executive) shall be considered third-party beneficiaries of the rights and
obligations created by this Section on Arbitration. Arbitrable Claims shall
include, but are not limited to, contract (express or implied) and tort claims
of all kinds, as well as all claims based on any federal, state, or local law,
statute, or regulation, excepting only claims under applicable workers'
compensation law and unemployment insurance claims. Arbitration shall be final
and binding upon the parties and shall be the exclusive remedy for all
Arbitrable Claims, except that Company may, at its option, seek injunctive
relief and damages in court for any breach of Sections 5 and 6 of this
Agreement. Subject to the foregoing sentence, THE PARTIES HEREBY WAIVE ANY
RIGHTS THEY MAY HAVE TO TRIAL BY JURY IN REGARD TO ARBITRABLE CLAIMS.

         (b) PROCEDURE. Arbitration of Arbitrable Claims shall be in
accordance with the Employment Dispute Resolution Rules of the American
Arbitration Association ("AAA Employment Rules"), except as provided otherwise
in this Agreement. Prior to resorting to arbitration, the complaining party must
first exhaust the procedures specified in the Company Employment Manual Section
3.4. Arbitration shall be initiated by providing written notice to the other
party with a statement of the claim(s) asserted, the facts upon which the
claim(s) are based, and the remedy sought. This notice shall be provided to the
other party within six (6) months of the acts or omissions complained of. Any
claim not initiated within this limitation period shall be null and void. EACH
PARTY WAIVES ALL RIGHTS UNDER STATUTES OF LIMITATIONS OF DIFFERENT DURATION. In
any arbitration, the burden of proof shall be allocated as provided by
applicable law. Either party may bring an action in court to compel arbitration
under this Agreement and to enforce an arbitration award. Otherwise, neither
party shall initiate or prosecute any lawsuit or administrative action in any
way related to any Arbitrable Claim. All arbitration hearings under this
Agreement shall be conducted in San Diego, California. The Federal Arbitration
Act shall govern the interpretation and enforcement of this Section 7.

          (c) ARBITRATOR SELECTION AND AUTHORITY. All disputes involving
Arbitrable Claims shall be decided by a single arbitrator. The arbitrator shall
be selected by mutual agreement of the parties within thirty (30) days of the
effective date of the notice initiating the arbitration. If the parties cannot
agree on an arbitrator, then the complaining party shall notify the AAA and
request selection of an arbitrator in accordance with the AAA Employment Rules.
The arbitrator shall have the authority to award equitable relief, damages,
costs, and fees as provided by law for the particular claim(s) asserted. The
fees of the arbitrator shall be split between both parties equally. The
arbitrator shall have exclusive authority to resolve all Arbitrable Claims,
including, but not limited to, any claim that all or any part of this Agreement
is void or unenforceable.

         (d) CONFIDENTIALITY. All proceedings and all documents prepared in
connection with any Arbitrable Claim shall be confidential and, unless otherwise
required by law, the subject matter thereof shall not be disclosed to any person
other than the parties to the proceedings, their counsel, witnesses and experts,
the arbitrator, and, if involved, the court and court staff. All documents filed
with the arbitrator or with a court shall be filed under seal. The parties shall
stipulate to all arbitration and court orders necessary to effectuate fully the
provisions of this subsection concerning confidentiality.

         (e) CONTINUING OBLIGATIONS. The rights and obligations of
Executive and Company set forth in this Section on Arbitration shall survive the
termination of Executive's employment and the expiration of this Agreement.

the Chairman of the Board of Directors or by his or her representative
specifically authorized to fulfill these obligations under this Agreement.

10.      INTEGRATION.

     This Agreement is intended to be the final, complete, and exclusive
statement of the terms of Executive's employment by Company. This Agreement may
not be contradicted by evidence of any prior or contemporaneous statements or
agreements. To the extent that the practices, policies, or procedures of
Company, now or in the future, apply to Executive and are inconsistent with the
terms of this Agreement, the provisions of this Agreement shall control.

                                       9
<PAGE>

11.      AMENDMENTS; WAIVERS.

         This Agreement may not be modified, amended, or terminated except by an
instrument in writing, signed by each of the parties. No failure to exercise and
no delay in exercising any right, remedy, or power under this Agreement shall
operate as a waiver thereof, nor shall any single or partial exercise of any
right, remedy, or power under this Agreement preclude any other or further
exercise thereof, or the exercise of any other right, remedy, or power provided
herein or by law or in equity.

12.      ASSIGNMENT; SUCCESSORS AND ASSIGNS.

         Executive agrees that he will not assign, sell, transfer, delegate, or
otherwise dispose of, whether voluntarily or involuntarily, or by operation of
law, any rights or obligations under this Agreement. Any such purported
assignment, transfer, or delegation shall be null and void. Nothing in this
Agreement shall prevent the consolidation of Company with, or its merger into,
any other entity, or the sale by Company of all or substantially all of its
assets, or the otherwise lawful assignment by Company of any rights or
obligations under this Agreement. Subject to the foregoing, this Agreement shall
be binding upon and shall inure to the benefit of the parties and their
respective heirs, legal representatives, successors, and permitted assigns, and
shall not benefit any person or entity other than those specifically enumerated
in this Agreement.

13.      SEVERABILITY.

         If any provision of this Agreement, or its application to any person,
place, or circumstance, is held by an arbitrator or a court of competent
jurisdiction to be invalid, unenforceable, or void, such provision shall be
enforced to the greatest extent permitted by law, and the remainder of this
Agreement and such provision as applied to other persons, places, and
circumstances shall remain in full force and effect.

14.      ATTORNEYS' FEES.

         In any legal action, arbitration, or other proceeding brought to
enforce or interpret the terms of this Agreement, the prevailing party shall be
entitled to recover reasonable attorneys' fees and costs.

15.      INJUNCTIVE RELIEF.

         If (i) Executive refuses to perform the responsibilities outlined in
Section 2 on Position and Responsibilities within the agreed upon Period of
Employment, and Executive has no right to terminate the employment relationship
pursuant to Section 4 on Termination of Employment, or (ii) Executive breaches
or threatens to breach any of the covenants in Section 5 on Proprietary
Information and Section 6 on Prior Knowledge and Information, the parties
acknowledge that the damage or imminent damage to Company's business or its
goodwill would be irreparable and extremely difficult to estimate, making any
remedy at law or in damages inadequate. Accordingly, Company shall be entitled
to injunctive relief against Executive in the event of any breach or threatened
breach of such provisions by Executive, in addition to any other relief
(including damages) available to Company under this Agreement or under law.

                                       10

receiving a benefit nor against the party responsible for any particular
language in this Agreement.

counsel in regard to this Agreement, that he has read and understands this
