                                     PART I

ITEM 1.   BUSINESS.

OVERVIEW

     The Company is a development stage enterprise organized in 1990 to design,
develop, manufacture and market propjet and jet aircraft intended primarily for
business use. The Company has obtained a type certificate ("Type Certificate")
from the Federal Aviation Administration ("FAA") with respect to a non-
pressurized, single-engine aircraft powered by a Pratt & Whitney propjet engine
(the "JETCRUZER 450"). The Company is modifying the JETCRUZER 450 to develop a
six-seat (including pilot), pressurized version of such aircraft for commercial
sale (the "JETCRUZER (TM)500") which, the Company anticipates, will takeoff and
land in less than 2,000 feet, be able to fly at 30,000 feet above sea level, and
have a high cruise speed of approximately 345 mph and a capability of flying
from Los Angeles to New York with only one stop.

     The Company began development of the JETCRUZER 450 in 1990 and obtained the
FAA Type Certificate approval in 1994. Throughout this period, the Company
engaged in design and engineering of the aircraft, as well as production of the
jigs, forms, tools, dies and molds necessary to manufacture the aircraft. The
first FAA conformed JETCRUZER 450 was completed in 1992. This aircraft was used
by the Company and the FAA to perform static (non-flight) testing. In late 1992
and 1993, two flight test aircraft were completed. These aircraft were flight
tested by the Company and the FAA from 1992 through 1994. The Company received
the FAA Type Certificate for the JETCRUZER 450 on June 14, 1994.

     Although the Company received preliminary written indications of interest
to purchase the aircraft, the Company decided that it would not obtain a
production certificate with regard to the JETCRUZER 450 or otherwise pursue
commercialization of that aircraft in part because the Type Certificate is
subject to certain limitations, which the Company believes reduce the commercial
viability of the JETCRUZER 450. Instead, the Company decided to amend the Type
Certificate to develop the JETCRUZER 500 for commercial sale. The JETCRUZER 500
is a modified version of the JETCRUZER 450 that the Company anticipates will not
be subject to the limitations imposed by the existing Type Certificate.

     The Company has FAA approval to amend its Type Certificate, rather than
obtain a new Type Certificate. The Company currently anticipates that it can
obtain an amendment to its Type Certificate during the last half of 2000 and
commence commercial production of such aircraft within the same time frame.
There can be no assurance, however, that obtaining the amendment will not take
longer than anticipated or that the Company will not experience unforeseen
expense or delay in certifying and commercializing its proposed aircraft.

     The Company has not generated any operating revenues to date and has
incurred losses from its operating activities including program development
costs of $5.6 million and $6.5 million in 1999 and 1998, respectively. The
Company believes it will continue to experience losses until such time as it
commences the sale of aircraft on a commercial scale. Research and development
expenses have consisted primarily of the costs of personnel, facilities,
materials and equipment required to conduct the Company's development
activities. Such expenses aggregated $31,527,000 from inception through December
31, 1999. Such expenses were incurred to develop the JETCRUZER 450, to obtain a
Type Certificate with respect thereto, and to begin the design of the JETCRUZER
500 and the STRATOCRUZER 1250 "See Other Aircraft".

INDUSTRY BACKGROUND

     The general aviation industry comprises essentially all nonmilitary
aviation activity other than scheduled and commercial airlines licensed by the
FAA and the Department of Transportation. General aviation aircraft are
frequently classified by their type and number of engines and include aircraft
with fewer than 20 seats. There are three different types of engines: piston,
propjet and turbofan (jet). Piston aircraft use an internal combustion engine to
drive a propeller and there may be one or two engines and propellers. Propjet
aircraft combine a jet turbine powerplant with a propeller geared to the main
shaft of the turbine and there may be one or two engines and propellers.
Turbofan aircraft use jet propulsion to power the aircraft. Although there are
usually two engines on general aviation turbofan aircraft, there may also be one
or three.

     Purchasers of general aviation aircraft include corporations, governments,
the military, the general public and fractional interest entities. A corporation
may purchase a general aviation aircraft for transporting its employees and
property. Many companies use an aircraft in their line of business, including
on-demand air taxi services, air ambulance services and freight and delivery
services. Governments and military organizations may purchase an aircraft for
the transportation of personnel, freight and equipment. Members of the general
public may purchase an aircraft for personal and/or business transportation,
freight, equipment and pleasure use. Fractional interest entities purchase one
or more aircraft and then sell interests in each aircraft to several persons or
entities. Each entity pays for its share of maintenance and operating costs and
its access to and use of the aircraft. Increased corporate earnings may
encourage corporations to acquire an aircraft. An aircraft must qualify under
FAA regulations in order to be used for certain purposes, and the ability of an
aircraft to so qualify will have a material affect on the potential market for
such aircraft.

     Currently, there are fewer than ten major manufacturers of general aviation
aircraft based in the United States. Piston aircraft make up the numerical
majority of aircraft delivered by these manufacturers, whereas propjets and jet
aircraft account for the majority of billings. Aircraft deliveries by United
States manufacturers have increased consistently with sales generating
approximately $3.1 billion in 1996, $4.8 billion in 1997,  $5.9 billion in 1998
and $7.9 billion in 1999.


STRATEGY

     The Company's objective is to become a worldwide market leader in the sale
and manufacture of small business aircraft. To achieve this objective, the
Company intends to focus on the performance, efficiency and safety of its
proposed aircraft, which will differentiate its aircraft from its competition.
The Company's strategy is to capitalize on a perceived lack of low-priced, high-
performance aircraft in the marketplace. The Company believes that its ability
to offer an aircraft which out performs competitive aircraft at a reduced cost
will enable the Company to penetrate the world business, private and government
aircraft markets. Additionally, the Company intends to expend substantial
resources on a worldwide sales and marketing program to position itself with
potential customers.

     The Company believes that aircraft sales are heavily dependent on the
quality and safety of a company's products. Accordingly, the Company intends to
maintain high quality and safety standards in all aspects of the design and
manufacture of its proposed aircraft. For example, the Company believes that
certain design features of the JETCRUZER 500, such as the canard wing, will make
the aircraft spin resistant and that the absence of wing flaps will make the
operation of the aircraft less susceptible to pilot error. In addition, the
Company believes that the reliability of the Company's component suppliers, such
as Pratt & Whitney, the engine manufacturer, will be viewed favorably by
potential customers.

     The Company believes that it will be able to offer aircraft at a
comparatively low price by containing the costs of obtaining FAA certification
and amendments to such certification as well as the costs of manufacturing. The
Company believes that it was able to obtain its Type Certificate for the
JETCRUZER 450 at a significantly lower cost than its competitors, with regard to
comparable aircraft, due, in part, to the Company's smaller size as compared to
its competitors, resulting in the Company's ability to contain administrative
costs and the overhead expenses allocable to the development process.
Additionally, the Company's Southern California location is home to a number of
workers from recently downsized aerospace and defense companies who the Company
was able to hire to assist in the certification of the JETCRUZER 450. These
employees provided the Company with an expertise in testing, certifying, tool
and jig manufacturing and other aspects of the certification process that would
not otherwise have been available to the Company.

     The Company believes that it will be able to control manufacturing costs by
producing most of the tooling, jigs, dies  and molds in-house required for the
manufacture of its aircraft. Also, because the Company produces the airframe and
most

                                       4
<PAGE>

of the associated components of its aircraft in-house, it will have greater
control over the production process; and the Company believes that this control
will also help keep construction and certification costs at reduced levels.


AIRCRAFT

     General. The Company's aircraft are based on a canard wing design in which
     -------
a smaller wing (the "canard") is installed in front of the aircraft's main wing.
The Company believes that this design provides for improved safety margins and
performance, including spin resistance and increased lift, and increased ride
comfort as compared to more conventional aircraft designs.

     The Company believes that the JETCRUZER 500 provides increased safety
margins, in part, because it will be certified under the latest safety
regulations adopted by the FAA. Additionally, the canard design, which provides
dual lifting surfaces, makes the JETCRUZER 500 resistant to spins. An airplane
may enter a spin when one main wing stalls (i.e. stops producing lift) before
the other. On the JETCRUZER 500, the canard wing will stall before the main rear
wing, thereby automatically lowering the aircraft's nose and increasing its
airspeed, thus preventing a stall of either of the main wings. Since the main
wing of the JETCRUZER 500 does not stall, it does not lose lift on one side
before the other and thus, in part, the aircraft is resistant to spins. The
JETCRUZER 500 has increased lift in part because the graphite composite fuselage
of the JETCRUZER 500 is lighter than a fuselage made of aluminum, used by most
of the Company's competitors, and the canard wing design provides an additional
lifting surface as compared to conventional aircraft. Generally, lighter weight
and additional lifting surfaces result in greater lifting capacity.

     Management also believes that the Company's aircraft will provide
performance advantages over competitors' models, including better handling
characteristics and increased speed. Based on the reports of its test pilots,
the Company also believes that the JETCRUZER 500 provides increased ride
comfort, and a quieter ride, than aircraft of a conventional design. The
JETCRUZER 500 will not require pilot licensing beyond that required for other
single-engine propjet aircraft.

     The fuselage of each aircraft is made of an advanced graphite
composite/nomex honeycomb sandwich with embedded aluminum and copper screen mesh
for lightning protection, which is processed in the Company's nitrogen-
pressurized autoclave. The canard wing on the JETCRUZER 500 is constructed of
aircraft aluminum. The main rear wing and the ailerons of all of the aircraft
are constructed of aircraft aluminum skin and spar and rib construction. Flaps
are not required on the JETCRUZER 500 because of the design and high lift
capabilities of the canard and the main wing. The engine and propeller of the
Company's JETCRUZER 500 aircraft are located at the rear of the fuselage, thus
providing passengers with a quieter ride.

     JETCRUZER500. The JETCRUZER 500 is a six-seat (including pilot), high
     ------------
performance single engine propjet with conventionally constructed wings made
from aluminum attached to a fuselage formed from a high-strength graphite nomex
honeycomb composite material. The aircraft has a canard configuration with two
lift-producing surfaces and no conventional wing flaps. The JETCRUZER 500 is
powered by a Pratt & Whitney PT6A-66A propjet engine located at the rear of the
aircraft. The JETCRUZER 500 is a modified version of the JETCRUZER 450.

     In June 1994, the FAA awarded the Company a Type Certificate for the
JETCRUZER 450, which is a non-pressurized propjet aircraft powered by a smaller
Pratt & Whitney engine. However, the Type Certificate is subject to a number of
FAA limitations that were imposed as a result of the aircraft's early stage of
development. For example, the maximum number of occupants was limited to five,
as compared to the six passenger (including pilot) design configuration of the
JETCRUZER 500, and the maximum operating speed was limited to 178 mph, as
compared to the approximately 345 mph design speed of the JETCRUZER 500. The
Company is amending the Type Certificate to remove these limitations in the
certification of the JETCRUZER 500.

     In order to amend the Type Certificate to include the JETCRUZER 500,
additional work is being performed on the aircraft by the Company, including
adding a larger fuselage, pressurization, environmental systems, de-icing
capability, and autopilot certification, all of which will be necessary to
produce the JETCRUZER 500 for commercial sale. Two model 500's have already been
produced and flown with the third anticipated to be completed in the second
quarter of 2000. The entire JETCRUZER program has almost a thousand hours of
flight testing. Several hundred additional hours of testing will be required to
obtain the amendment of the Type Certificate. The Company anticipates the
certification amendment will be received in the second half of 2000. There can
be no assurance, however, that obtaining the amendment will not take longer than
anticipated.

                                       5
<PAGE>

     Although no assurance can be given as to the performance characteristics of
any aircraft in its design phase, based on the performance of the JETCRUZER 450,
the Company believes that the JETCRUZER 500 will carry six passengers (including
pilot) and have a cruise speed of approximately 345 mph. The Company also
believes that the aircraft should be able to climb at approximately 2,600 feet
per minute, cruise at an altitude of 30,000 feet above sea level and travel from
Los Angeles to New York with only one stop. The interior of the aircraft will be
built either to a customer's specifications or in accordance with one of the
Company's standard configurations. These statistics reflect the overall
anticipated performance of the JETCRUZER 500. However, interior configuration,
optional equipment, weather conditions and flying weight will affect the
performance of an individual aircraft. The JETCRUZER 500 currently is available
for commercial sale at a base price of $1,495,000.


OTHER AIRCRAFT

     STRATOCRUZER(R)1250. The Company currently intends to further develop a
     -------------------
twin engine jet aircraft called the STRATOCRUZER 1250. The STRATOCRUZER 1250,
will be a canard aircraft with three flying surfaces powered by two
Williams/Rolls Royce FJ44-2 fan jets. It will seat up to 12 passengers, plus the
pilot. Based on its design and preliminary testing, it is anticipated that the
STRATOCRUZER 1250 will have a maximum cruise speed of approximately 500 mph, a
range of approximately 3,700 miles and a pressurized ceiling of 41,000 feet. The
STRATOCRUZER 1250 will be able to takeoff in less than 3,200 feet and land in
less than 3,000 feet. The instrumentation of the STRATOCRUZER 1250 will consist
of digital electronic avionics, including EFIS (an Electronic Flight
Instrumentation System, which includes color monitors on which flight instrument
data, weather radar, maps and other navigation information are available) and
GPS (Global Positioning System) navigation. The aircraft will be of lightweight
construction. The Company believes that the STRATOCRUZER 1250's comparatively
light weight, combined with, among other things, its additional lifting
surfaces, fuel efficient engines and aerodynamic design, will give the
STRATOCRUZER 1250 superior range and fuel efficiency compared to other twin
jets. The Company will be required to obtain a new FAA type certificate for the
STRATOCRUZER 1250.

     The STRATOCRUZER 1250 is in a very early stage of development, and the
completion of such development will also require substantial capital resources
beyond those which the Company currently possesses. Therefore, there can be no
assurance that the Company will obtain the capital resources necessary to
continue the development of the STRATOCRUZER 1250 or, if such resources are
obtained, successfully develop and certify the STRATOCRUZER 1250. Accordingly,
the Company cannot predict when, if ever, the STRATOCRUZER 1250 will be
available for commercial sale.


MANUFACTURING

     The Company has designed, produced or procured most of the equipment
necessary for production of the JETCRUZER 450 and has used that equipment to
certify the aircraft. The Company is in the process of obtaining and producing
additional sets of the equipment necessary for production of the JETCRUZER 500.
The Company will produce, in-house, substantially all of the tooling necessary
for the production of its aircraft, from master models to major jigs and
fixtures. The Company believes it has achieved, and will continue to achieve,
cost savings by manufacturing tooling in-house. Additionally, nearly all
airframe assemblies and parts are intended to be produced in-house, except for
special tasks such as spar milling and painting. The manufacturing process for
the Company's aircraft is highly technical and requires skilled assembly
technicians. The Company believes that a number of such skilled individuals are
available in Southern California in general, and in Long Beach in particular.
However, no assurance can be given that these individuals will in fact be
available to the Company.

     The equipment and procedures used by the Company for manufacturing must be
certified, and are subject to inspection and continuing oversight, by the FAA.

     The Company has a complete in-house computer design system, with
interactive, computer-aided design ("CAD") capabilities. The Company maintains
an Aircraft Quality Control System ("AQCS") designed to meet the requirements of
the military, the National Aeronautics and Space Administration ("NASA") and the
FAA. An AQCS is a system mandated and approved by the FAA to assure the
integrity and traceability of aircraft components, parts, and systems. It is
required as a condition to obtaining a type certificate and a production
certificate. All of the Company's precision tools and gauges are certified by
the National Bureau of Standards.

                                       6
<PAGE>

     The Company will manufacture the advanced graphite composite fuselage
structure used in the construction of its aircraft in its own computer-
controlled, nitrogen-pressurized autoclave. The autoclave was purchased new in
1990 and was used in the construction of the certification aircraft. It can
achieve temperatures of up to 650 degrees Fahrenheit and pressure of 150 pounds
per square inch. The graphite material is very strong and lightweight. In the
course of certifying the JETCRUZER 450, the Company believes it has demonstrated
to the FAA that the graphite material meets or exceeds all standards set by the
FAA for aircraft construction material. Use of the graphite composite material
simplifies the manufacturing process because, unlike metal construction, it
eliminates most riveting, which is a labor intensive, time consuming process.
The graphite sections are bonded together through a process which provides
strength equal to or greater than riveting. The metal wings of the aircraft are
attached to the composite portions of the airframe through a manufacturing
technique developed by the Company.


MARKETING, DISTRIBUTION AND SERVICE

     The Company has developed an in-house sales and marketing organization and
is marketing its aircraft in the United States and abroad through trade
publications, news releases, attendance at aircraft trade shows, and independent
distributors and agents.

     The Company's marketing and sales efforts to date have emphasized aircraft
trade shows, from which a significant amount of new aircraft orders have been
generated. The Company participates in numerous air shows, including the Paris
Air Show, the National Business Aircraft Association USA Show and the Singapore
Aerospace Show. Management believes that, in addition to sales generated
directly from such events, participation in trade shows introduces the Company's
aircraft to potential purchasers and increases overall awareness of the
Company's products. The Company also promotes general knowledge of the Company's
products by issuing press releases to aviation magazines and newspapers. The
Company also uses paid advertising in trade magazines, general interest flying
magazines and international business magazines to promote its products.

     Management anticipates that most of the Company's aircraft will be sold to
corporations for transportation of their personnel, guests and company property.
The Company has developed direct marketing programs to target such corporations.
The Company believes that its aircraft will also be attractive to customers
other than corporations and is addressing these markets as well. These markets
include current owners of single and twin engine aircraft who operate their own
aircraft for business purposes, governmental entities that use aircraft for
transportation, surveillance, mapping photography, forest fire detection, and
fractional use entities who purchase one or more aircraft and sell interests in
each aircraft to several persons or entities. The Company believes that the
relatively low purchase price, performance, safety and cost of operating its
aircraft will make them attractive to such purchasers. Other potential specialty
markets may include air freight and delivery services, on-demand air taxi
services and/or charter and air ambulance use.

     Pursuant to FAA regulations effective as of May 4, 1998, single-engine
aircraft may be used for commercial passenger revenue-paying flights (whether
on-demand charter or scheduled) in Instrument Flight Rules (IFR) conditions,
provided the pilot and the aircraft meet certain FAA certification, proficiency,
maintenance and additional equipment and airworthiness requirements. The Company
believes that the affect of this FAA resolution will be to open up new markets
for the JETCRUZER 500.

     The Company intends to provide referral assistance to customers who require
financing to complete the purchase of an aircraft from the Company. Overseas
sales may be financed through the United States Export/Import Bank ("EXIM"),
which may provide loans to qualified overseas customers, and through several
domestic banks. Additionally, EXIM may provide low-cost working capital loans to
the Company upon the receipt of evidence of export sales commitments.

     SERVICE. The Company's aircraft will be serviced primarily by fixed base
     -------
operations ("FBOs") authorized by the Company. FBOs are established aircraft
maintenance companies located at airports throughout the world which service
general aviation aircraft produced by virtually all major aircraft
manufacturers. If and when customers in a particular region or country begin to
acquire aircraft manufactured by the Company, an appropriate FBO for that area
will be identified and authorized by the Company after consultation with the
agent and/or distributor for that area. The Company will provide training and a
service manual to the employees of its authorized FBO's. Required parts and
repair materials will be air freighted to the FBO's as required. Maintenance and
repair of major systems included in the Company's aircraft, such as engines and
avionics, will be provided by the manufacturers of those systems.

SUPPLIERS

     The Company relies on various suppliers of materials and components which
are necessary to manufacture its aircraft. In particular, the engines and the
avionics are provided by outside manufacturers. These suppliers also produce
equipment for aircraft manufacturers other than the Company. Engines for the
JETCRUZER 500 are manufactured by Pratt & Whitney. Engines for the STRATOCRUZER
1250, if developed, will be manufactured by Williams/Rolls Royce. The Company
has contractual rights to engines from Pratt & Whitney. The failure of suppliers
or subcontractors to meet the Company's performance specifications, quality
standards or delivery standards or schedules could have a material adverse
effect on the Company's operations. Moreover, the Company's ability to
significantly increase its production rate following the introduction of the
JETCRUZER 500 could be limited by the ability or willingness of its key
suppliers to increase their delivery rates.


COMPETITION

     The JETCRUZER 500 will compete against several other types of aircraft,
including new and used single and multi-engine propjets and high-end piston
powered aircraft. Management believes its aircraft will be differentiated from
its  competition based primarily on the aircraft's price and performance. Single
engine propjets have only recently come into use in the general aviation
industry, and there are not many competitors in this category. Twin engine
propjets are far more common and vary significantly in size.

     Single engine propjet competition for the JETCRUZER consists of just three
aircraft. The Cessna Caravan is all metal and sells for $1.4 million and has a
high speed of 160 kts, a landing gear that does not retract, no pressurization
and is designed basically for freight use. Cessna delivered 700 Caravans in 7
years and received an order for 100 aircraft from one customer. The Company also
expects competition from the TBM 700. Made in France from metal, it has a
similar passenger capacity and performance to the JETCRUZER, but its $2.6
million price tag is almost double that of the JETCRUZER. The last competitor is
the Pilatus PC-12. Made in Switzerland from metal, it has a lower airspeed of
270 kts and sells for almost double the price of the JETCRUZER at $2.4 million.
All competitive aircraft are based on conventional designs, which are more than
30 years old, and are made from metal. JETCRUZER's prime advantage is its
design, lightweight graphite composites, high performance and is one of the
lowest priced propjets in the world.

     An additional competitor to the JETCRUZER 500 could be  the Malibu Mirage.
The Malibu Mirage is a single engine piston powered aircraft, rather than a
propjet. It is manufactured in the United States by The New Piper Aircraft Corp.
It has an airspeed of 267 miles per hour and a range of approximately 1,200
miles. The Company believes that piston aircraft such as the Mirage, and propjet
aircraft such as the JETCRUZER 500 compete for different customers based on
performance, speed and reliability. However, the price differential may induce
certain purchasers to select the lower-priced piston aircraft.

     The Company believes that the JETCRUZER 500 may compete with and compare
favorably to various twin engine propjets, such as the King Air C-90B, in
airspeed and passenger seating at a significantly lower purchase price and
operating cost. The King Air C-90B is a twin engine propjet of conventional
design which is manufactured in the United States by Raytheon Aircraft Co.
(Beechcraft). It has an airspeed of approximately 284 miles per hour and has
seven seats. Its approximate base price is $2,488,000. However, certain
customers may be reluctant to purchase a single-engine aircraft such as the
JETCRUZER 500 due to the perception of additional safety associated with twin-
engine aircraft.

     Most of the Company's competitors are substantially larger in size and have
far greater financial, technical, marketing, and other resources than the
Company. Certain of the Company's actual and potential competitors may have
technological capabilities or other resources that would allow them to modify
existing aircraft or develop alternative new aircraft which could compete with
the Company's aircraft. Therefore, there can be no assurance that future
technological changes or marketing initiatives on the part of its competitors
will not have a material adverse effect on the Company's ability to market its
aircraft.

     Additionally, indirect competition and potential sales will come from the
used aircraft market, both propjets and jets, which have sales prices near that
anticipated for the JETCRUZER 500. As the prices of new aircraft have increased,
buyers have turned in greater numbers to the used aircraft market. The Company,
however, believes that it may be able to attract

                                       8
<PAGE>

purchasers who might otherwise acquire a used aircraft by emphasizing the price,
performance and technology, of the Company's aircraft.

     PRODUCT LIABILITY AND INSURANCE. The failure of an aircraft manufactured by
     -------------------------------
the Company or any other mishap involving such an aircraft may result in
physical injury or death to the occupants of the aircraft or others, and
therefore, the Company could be subject to lawsuits involving product liability
claims. The Company intends to obtain product liability insurance for aircraft
purchased by customers before the delivery of the first customer's aircraft.
However, such insurance is expensive, subject to various exclusions and,
although the product liability insurance for manufacturers of general aviation
aircraft has become somewhat more available and less costly over the last two
years, there can be no assurance that such coverage will be available to the
Company on acceptable terms or at all. Further, should the Company become
involved in product liability litigation, the expenses and damages awarded could
be large and the scope of any coverage may be inadequate. The Company has
obtained other insurance as needed, including flight test insurance for its
pilots and aircraft used during the FAA certification process.

GOVERNMENT REGULATION

     The manufacture of aircraft is subject to extensive regulation by the FAA.
Both the finished product and the process of manufacturing itself must be
certified by the FAA, as must the type design. Failure to obtain or maintain all
required FAA certifications would have a material adverse effect on the
Company's operations.

     CERTIFICATION. On June 14, 1994, the Company obtained a Type Certificate
     -------------
from the FAA for the JETCRUZER 450. For an aircraft model to be manufactured for
sale, the FAA must issue a type certificate and production certificate for that
model; for an individual aircraft to be operated, the FAA must issue an
airworthiness certificate for that aircraft. Type certificates are issued by the
FAA when an aircraft model is determined to meet applicable performance, safety,
environmental, and other technical criteria. In the case of aircraft such as the
Company's which have one or more unconventional design characteristics for which
there are no applicable criteria, such criteria are developed and applied in the
course of the type certification process. More stringent airworthiness criteria
and additional equipment requirements become applicable if the aircraft will be
used in commercial passenger operations, whether on-demand charter or scheduled.
Production certificates are issued by the FAA after it determines that the type
certificate holder (or its licensee) has the facilities and quality control
capability to manufacture aircraft that will meet the design provisions of the
applicable type certificate. An airworthiness certificate is issued by the FAA
for a particular aircraft when it is certified to have been built in accordance
with specifications approved under the type certificate for that model; the
airworthiness certificate remains in effect so long as required maintenance,
repairs and upkeep are performed.

     The Company is in the process of amending its Type Certificate with respect
to the JETCRUZER 450 to include the JETCRUZER 500.  The Company will be required
to obtain a new type certificate if and when it proceeds with development of the
STRATOCRUZER 1250.

     Obtaining an amended FAA type certificate can be difficult, costly, and
time consuming. To date, the Company has accomplished, among other things, (a)
the filing of an appropriate application with the FAA, (b) development and
submission to the FAA of an appropriate design and substantiating data and
receipt of FAA approval that such design and data comply with applicable FAA
airworthiness standards, (c) development and receipt of FAA approval of a flight
test plan, and (d) construction of an initial prototype JETCRUZER 500 for use in
flight testing and construction of a flight test Jetcruzer 500, currently in
flight testing. The Company must accomplish the following before receiving an
amendment to its Type Certificate for the JETCRUZER 500: (a) successful
completion of conformity inspections requested by the FAA from time to time to
ensure compliance of the aircraft with the type design, (b) completion of the
JETCRUZER 500 fuselage for static tests and the completion of the JETCRUZER 500
for flight tests, (c) completion of Company flight tests and receipt of
precertification approval from the FAA, (d) completion of additional flight
tests under FAA supervision, (e) development and receipt of FAA approval of an
airplane flight manual, and (f) development and receipt of FAA approval of
maintenance and inspection requirements for the aircraft. Although the time
required to obtain an amended type certificate may vary, the Company believes
that it can obtain an amended certificate for the JETCRUZER 500 during the last
half of 2000.

     The Company intends to obtain a FAA production certificate for the
commercial production of its aircraft. In order to obtain a production
certificate, the Company must commence production of an aircraft and make
application for the certificate. The FAA will regularly inspect the Company's
facilities and procedures during the production process.

     When the initial aircraft is nearly complete, the Company must have
submitted all required materials, including a copy of the applicable quality
assurance manual. The FAA will then review the materials submitted and the
results of its

                                       9
<PAGE>

inspections and will either issue the production certificate or require that the
Company modify its quality assurance manual or the manufacturing process, or
both. While production will not necessarily stop during the review process, a
failure to receive a production certificate would likely delay the manufacturing
process. The time required to obtain a production certificate is identical to
and concurrent with the time required to manufacture the first commercially-
produced applicable aircraft; which the Company believes will be five to six
months in the case of the JETCRUZER 500. The Company expects to obtain the
production certificate during the last half of 2000.

     There can be no assurance that the Company will not encounter a delay in
obtaining a production certificate for its planned aircraft models or
airworthiness certificates for individual aircraft.

     The Company will also be subject to the risk of modification, suspension or
revocation of any FAA certificate it holds. Such modification, suspension, or
revocation could occur if, in the FAA's judgement, compliance with airworthiness
or safety standards by the Company is in doubt. If the FAA were to suspend or
revoke the Company's type or production certificates for an aircraft model,
sales of that model would be adversely affected or terminated. If, in the FAA's
judgement, an unsafe condition developed or was discovered after one or more of
the Company's aircraft had entered service, the FAA could issue an
"Airworthiness Directive," which could result in a regulatory obligation upon
the Company to develop appropriate design changes. Foreign authorities could
impose similar obligations upon the Company as to aircraft within their
jurisdiction. Any or all of the above occurrences could expose the Company to
substantial additional costs and/or liability.

     PRODUCT LIABILITY. In 1994, the United States Congress passed and the
     -----------------
President signed the General Aviation Revitalization Act of 1994 ("GARA"). GARA
provides protection for manufacturers of general aviation aircraft against
certain lawsuits for wrongful death or injuries resulting from an aircraft
accident. Except as set forth in GARA, and provided a period of 18 years has
passed from the date of delivery of the aircraft to the original purchaser or
retailer, no claim for damages resulting from personal injury or wrongful death
may be brought against the manufacturer of a general aviation aircraft. Although
GARA will not directly affect the Company until eighteen years from the date it
delivers its first aircraft, management believes that GARA will indirectly
benefit the Company immediately, in that it may encourage increased
manufacturing and sales of general aviation aircraft and this increased activity
may in turn result in an increased number of licensed pilots. Management
believes that a greater number of licensed pilots may provide an increased
market for the Company's aircraft. However, there can be no assurance that
Management's view of GARA's effects will prove to be correct.

     FOREIGN CERTIFICATION. In order for the Company to sell its aircraft in
     ---------------------
foreign countries, it must comply with each country's aircraft certification
process. Certain countries will accept as adequate the certification issued by
the FAA, while others impose additional requirements. In countries which do
require additional certification, the FAA certification often provides a
starting point from which such country begins its certification process. The
Company intends to begin certification processes in a foreign country once it
has received the amendment to the Type Certificate for the JETCRUZER 500 and has
finalized a sale or distributorship in that country. The Company has not yet
determined which foreign markets it will first address. Priorities in this area
will be established by the levels of interest in the Company's products of
dealers and distributors in the various foreign markets.


EMPLOYEES

     As of March 9, 2000 the Company had ninety-four full time employees. The
Company believes that its relations with its employees are good. The Company is
not a party to any collective bargaining agreement.


ITEM 2.    PROPERTIES.

     The Company leases approximately 10 acres of land located on the Long Beach
Airport in Long Beach, California. The lease commenced on January 14, 1998 and
has a term of 30 years with an option to renew for an additional 10 year term.
The lease also contains options to lease other airport properties. The current
monthly rent under the lease is $7,400.  The lease contains incremental
increases which escalate the monthly rent to approximately $15,600 after 5
years.

     The Company contracted Commercial Developments International/West
(Design/Builder) to design and build their approximately 200,000 square foot
manufacturing and headquarters facility (the "New Facility") on the above
mentioned leased property. The facility was substantially completed during 1998,
and on November 16, 1998, the Company moved into

                                       10
<PAGE>

the New Facility. The total cost for the New Facility, including its design,
construction, licenses, fees and change orders was approximately $9,700,000. The
Company believes the new facility will provide adequate capacity for the
foreseeable future.

     In June, 1999, the Company sold its 200,000 square-foot building and leased
it back. The sales price of the building was $9,800,000 and the term of the
lease is eighteen years plus an option to extend the lease for an additional ten
years.

     Monthly payments under the terms of the leaseback are approximately
$106,000 and will be adjusted annually, after the first year, for changes in the
Consumer Price Index, not to exceed 3% per annum. The rent for periods after the
eighteenth year will be at fair market rental value.



ITEM 3.    LEGAL PROCEEDINGS.

     As of March 15, 2000, there were no material pending legal proceedings to
which the Company was a party or to which any of its properties were subject.


ITEM 4.    SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     No matters were submitted to a vote of the security holders of the Company
during the fourth quarter of 1999.

ITEM 6. MANAGEMENT'S DISCUSSION AND ANALYSIS

     Certain statements concerning the Company's future cash and financing
requirements, the Company's ability to raise additional capital, the Company's
ability to obtain market acceptance of its aircraft, the Company's ability to
obtain regulatory approval for its aircraft, and the competitive market for
sales of small business aircraft and other statements contained herein regarding
matters that are not historical facts, are forward looking statements; actual
results may differ materially from those set forth in the forward looking
statements, which statements involve risks and uncertainties, including without
limitation those risks and uncertainties set forth in the Company's Registration
Statement on Form SB-2 (333-12273) under the heading "Risk Factors."

                               PLAN OF OPERATIONS

     The following discussion and analysis should be read in conjunction with
the financial statements and notes thereto appearing elsewhere in this report.

GENERAL

     The Company is a development stage enterprise organized to design, develop,
manufacture and market propjet and jet aircraft intended primarily for business,
corporate and government use and has been engaged principally in research and
development of its proposed aircraft. At inception in January 1990, the Company
acquired the assets of Aerodynamics & Structures, Inc. ("ASI"), a New Jersey
corporation engaged in the design of an aircraft prototype, in exchange for
139,407 shares of Class B Common Stock, 278,815 shares of Class E-1 Common
Stock, and 278,815 shares of Class E-2 Common Stock. In connection with this
exchange, the Company assumed liabilities of ASI in the amount of approximately
$400,000. In March 1990, the Company made application to the FAA for a Type
Certificate for the JETCRUZER 450, which Certificate was ultimately granted in
June 1994. The Company decided to amend the Type Certificate and is in the
process of developing the JETCRUZER 500 for commercial sale, which is a modified
version of the JETCRUZER 450, that the Company anticipates will not be subject
to the limitations imposed by the existing Type Certificate.

     The Company has not generated any operating revenues to date and has
incurred losses from its operating activities including program development
costs of $5.6 million and $6.5 million in 1999 and 1998, respectively. The
Company believes it will continue to experience losses until such time as it
commences the sale of aircraft on a commercial scale.

     Prior to commencing commercial deliveries, the Company will need to, among
other things, complete the development of the JETCRUZER 500, obtain the
requisite regulatory approvals, hire additional engineering and manufacturing
personnel and expand its sales and marketing efforts. The Company estimates that
the cost to complete development of the JETCRUZER 500 and obtain an amendment of
its FAA Type Certificate will be approximately $5,000,000. This amount includes
the cost of equipment and tooling, static and flight-testing of the aircraft,
and the employment of the necessary personnel to build and test the aircraft.
There can be no assurances, however, that the Company's cost to complete
development of the JETCRUZER 500 will not exceed $5,000,000.

     At such time, if ever, as the Company commences the commercial sale of its
aircraft, the Company will derive a substantial portion of its revenues from the
sale of a relatively small number of aircraft. As a result, a small reduction in
the number of aircraft shipped in a quarter could have a material adverse effect
on the Company's financial position and results of operations for that quarter.
The Company's policy is to collect progress payments during the construction of
aircraft and final payments upon the delivery of aircraft. Construction or
delivery delays near the end of a particular quarter, due to, for example,
shipment rescheduling, delays in the delivery of component parts or unexpected
manufacturing difficulties experienced by the Company, could cause the financial
results of the quarter to fall significantly below the Company's expectations
and could materially and adversely affect the Company's financial position and
results of operations for the quarter.

     During 2000 the Company intends to focus its efforts on the following
events:

     -   Passing the FAA pressurization test. One of the major differences
         between the JETCRUZER 500 and the JETCRUZER 450 is that the JETCRUZER
         500 is pressurized. After the JETCRUZER 500 passes the pressurization
         test, the Company believes that the remaining tests are tests that have
         previously been performed

                                       13
<PAGE>

         on the JETCRUZER 450 and, therefore, are more likely to be successful.
         While there can be no assurance, the Company believes that the
         pressurization test can be successfully completed in the first quarter
         of the year 2000.

     -   Completing Company high-speed cruise flight-testing to assure customers
         of the JETCRUZER 500's speed.

     -   The commencement of JETCRUZER 500 production. Upon the successful
         completion of the pressurization and Company speed tests, the Company
         immediately will commence production of the first JETCRUZER 500 planes.
         The Company anticipates that production will start in lots of 4 planes
         per month.

     -   The start of progress payment collections. As the Company starts the
         production process, each customer whose plane is being built will be
         requested to make an initial progress payment, as specified in the
         customer's purchase contract. The Company believes that this event will
         be the start of positive cash flow.

     -   Obtaining Type Inspection Authorization (TIA). This event marks the end
         of Company flight tests and means that the FAA will test the plane,
         using its pilots. The Company believes that this event will occur
         around the middle of year 2000.

     -   Obtaining an amended Type Certificate (TC) for the Jetcruzer 500 from
         the FAA. This means that the Company may deliver planes to its
         customers. The Company believes that this event will occur toward the
         end of year 2000.

     -   Delivering the first JETCRUZER 500. With the delivery of its first
         plane, the Company will record its first sales revenue and cost of
         goods sold.

     -   Obtaining a production certificate from the FAA. This will allow use of
         the Company's specified inspectors during the production and delivery
         processes of the JETCRUZER 500. This certification should quickly
         follow the receipt of the TC.

         The Company entered into a subscription agreement for the sale of up to
$10,000,000 of 5% Cumulative Convertible Series A Preferred Stock, of which the
Company received net proceeds of $4,550,000. Additionally, the Company signed a
letter of intent to sell and leaseback manufacturing equipment. This transaction
will generate an additional $1,000,000.

       The Company's management believes that its current working capital with
the additional funding obtained in March 2000 will be sufficient to finance its
plan of operations through the end of the third quarter, at which time positive
cash flow from customer progress payments is expected to have commenced as well
as receipt of the remaining $5,000,000 of the Preferred Stock funding will have
occurred. However, there can be no assurances that the current timetable for
completion of the development and certification of the aircraft will not be
delayed beyond the current fiscal year. If the Company's estimates prove to be
incorrect, or additional sources of financing prove to be unavailable, if
needed, the Company will have to curtail its development plans.

</TABLE>

     The Company has not generated any revenues from operations.. The Company's
losses have resulted primarily from expenditures made in connection with the
research and development of the Company's proposed aircraft and general and
administrative activities. During 1996 the Company incurred an extraordinary
loss of $942,000, resulting from the retirement of debt at the time of its
December 1996 IPO.

     Interest income consisted primarily of earnings derived from the unused
proceeds of the 1999 sale and leaseback of the Company's 200,000 square foot
building.  Interest income aggregated $2,743,000 from inception through December
31, 1999, $927,000 and $373,000 of which was earned in 1998 and 1999,
respectively.

     Research and development expenses have consisted primarily of the costs of
personnel, facilities, materials and equipment required to conduct the Company's
development activities. Such expenses aggregated $31,527,000 from inception
through December 31, 1999. Such expenses were incurred to develop the JETCRUZER
450, to obtain a Type Certificate with respect thereto, and to begin the design
of the JETCRUZER 500, and the STRATOCRUZER 1250.

     General and administrative expenses have consisted primarily of
administrative salaries and benefits, rent, marketing expenses, insurance and
other administrative costs. Such expenses aggregated $17,878,000 from inception
through December 31, 1999, $4,658,000 and $3,186,000 of which were incurred in
1998 and 1999, respectively. General and administrative expenses have increased
since 1997 primarily due to the addition of personnel and other resources needed
to support increased administrative, marketing, and development activities.

     Interest expense has consisted primarily of interest expended by the
Company for bank and private financing. Interest expense aggregated $3,345,000
from inception through December 31, 1999, $352,000 and $992,000 of which were
incurred in 1998 and 1999, respectively.

     The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes." The
Company has incurred net losses in each year since its inception and
consequently has paid no federal or state income taxes.

     At December 31, 1999, the Company has a United States federal and
California state tax net operating loss carryforwards of approximately
$47,900,000 and $15,200,000, respectively, which, if unused, will expire in
varying amounts in the years 1999 through 2018.

     At December 31, 1999, the Company had federal and state research and
development ("R&D") credit carryforwards of approximately $ 1,356,000 and
$542,000, respectively. The federal R&D credit carryforwards will expire in the
years 2004 through 2009. The state R&D credit carryforwards can be carried
forward indefinitely. See Note 5 of Notes to Financial Statements.

LIQUIDITY AND CAPITAL RESOURCES

     At December 31, 1999, the Company had working capital of $1,731,000 and
stockholders' equity of $1,604,000. Since its inception in January 1990, the
Company has experienced continuing negative cash flow from operations, which,
prior to the December 1996 IPO, resulted in the Company's inability to pay
certain existing liabilities in a timely manner. The Company has financed its
operations through private funding of equity and debt and through the proceeds
generated from its December 1996 initial public offering.

     The Company expects to continue to incur losses until such time, if ever,
as it obtains regulatory approval for the JETCRUZER 500 and related production
processes and market acceptance for its proposed aircraft at selling prices and
volumes which provide adequate gross profit to cover operating costs and
generate positive cash flow. The Company's working capital requirements will
depend upon numerous factors, including the level of resources devoted by the
Company to the scale-up of manufacturing and the establishment of sales and
marketing capabilities and the progress of the Company's research and
development program for the JETCRUZER 500 and other proposed aircraft.

     The Company's management team has developed a financial plan to address its
working capital requirements. The Company entered into a subscription agreement
for the sale of up to $10,000,000 of 5% Cumulative Convertible Series A
Preferred Stock, of which the Company received net proceeds of $4,550,000.
Additionally, the Company signed a letter of intent to sell and leaseback
manufacturing equipment. This transaction will generate an additional
$1,000,000.

     The remaining $5,000,000 in Preferred Stock funding will not occur until
certain criteria have been met, including passing the pressurization test for
the fuselage structure and completion of the registration of 200% of the Common
Stock underlying the convertible Preferred Stock subscription. It is anticipated
that the remaining proceeds will be received in two installments; $2 million in
the second quarter and the final $3 million in the third quarter, upon the
commencement of production of the aircraft.

     While there is no assurance that additional financing will be available,
the Company's management believes that it has developed a financial plan that,
if executed successfully, will substantially improve the Company's ability to
meet its working capital requirements. This financial plan includes the
commencement of production and the collection of progress payments to assist
with the working capital requirements. However, there can be no assurances that
the current timetable for completion of the development and certification of the
aircraft and commencement of production will not be delayed beyond the current
fiscal year. If the Company's estimates prove to be incorrect, or additional
sources of financing prove to be unavailable, if needed, the Company will have
to curtail its development plans.

     In November 1998 the Company moved into its manufacturing and headquarters
facility. The primary financing for this project was the Company's obligation
under a loan agreement related to proceeds received from $8,500,000 in the
issuance of Industrial Development Bonds (IDB) by the California Economic
Development Financing Authority (the "Authority"). The Company was required to
provide cash collateral to The Sumitomo Bank, Limited (the "Bank") in the amount
of $8,500,000 for a stand-by letter of credit in favor of the holders of the
IDBs which was to expire on August 5, 2002, if not terminated earlier by the
Company or the Bank. The IDBs were retired in 1999 and the stand-by letter of
credit in favor of the holders of the IDBs was terminated by the Company.

     In June, 1999, the Company sold its 200,000 square-foot building to The
Abbey Company and leases it back. The purchase price of the building was
$9,800,000 and the term of the lease is eighteen years plus an option to extend
the lease for an additional ten years. Monthly payments under the terms of the
leaseback are approximately $106,000 and will be adjusted annually, after the
first year, for changes in the Consumer Price Index, not to exceed 3% per annum.
The rent for periods after the eighteenth year would be at fair market rental
value.

     The Company leases approximately 10 acres of land located on the Long Beach
Airport in Long Beach, California. The lease commenced on January 14, 1999 and
has a term of 30 years with an option to renew for an additional 10 years. The
lease also contains options to lease other airport properties. An escalation
clause in the lease increases the monthly rent to $7,400 beginning July 1999.
The lease contains incremental increases that escalate the monthly rent to
approximately $15,600 after 5 years.

<PAGE>

     The Company had no material capital commitments at December 31, 1999, other
than discussed elsewhere in this report. The Company intends to hire a number of
additional employees, which will require substantial capital resources. The
Company anticipates that it will hire up to 200 employees over the next twelve
months, including engineers and manufacturing technicians necessary to produce
its aircraft.

SEASONALITY

The Company believes its business is not seasonal.

IMPACT OF YEAR 2000

In prior years, the Company discussed the nature and progress of its plans to
become Year 2000 ready. In late 1999, the Company completed it remediation and
testing of systems. As a result of those planning and implementation efforts,
the Company experienced no significant disruptions in mission critical
information technology and non-information technology systems and believes those
systems successfully responded to the Year 2000 date change. Amounts expensed by
the Company during 1999 in connection with remediating its systems were
immaterial. The Company is not aware of any material problems resulting from
Year 2000 issues, either with its products, its internal systems, or the
products and services of third parties. The Company will continue to monitor its
mission critical computer applications and those of its suppliers and vendors
throughout the year 2000 to ensure that any latent Year 2000 matters that may
arise are addressed promptly.


CONVERSION OF PERFORMANCE SHARES

     In the event the Company attains certain earnings thresholds or the
Company's Class A Common Stock meets certain minimum bid price levels, the Class
E Common Stock will be converted into Class B Common Stock. In the event any
such converted Class E Common Stock is held by officers, directors, employees or
consultants, the maximum compensation expense recorded for financial reporting
purposes will be an amount equal to the fair value of the shares converted at
the time of such conversion which value cannot be predicted at this time.
Therefore, in the event the Company attains such earnings thresholds or stock
price levels, the Company will recognize a substantial charge to earnings during
the period in which such conversion occurs, which would have the effect of
increasing the Company's loss or reducing or eliminating its earnings, if any,
at that time. In the event the Company does not attain these earnings thresholds
or minimum bid price levels, and no conversion occurs, no compensation expense
will be recorded for financial reporting purposes.

To the Board of Directors
Advanced Aerodynamics & Structures, Inc.

     We have audited the accompanying balance sheet of Advanced Aerodynamics &
Structures, Inc. (a development stage enterprise) as of December 31, 1999, and
the related statements of operations, stockholders' equity, and cash flows for
the two years then ended, and for the period from January 26, 1990 (inception)
through December 31, 1999. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

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

     In our opinion the financial statements referred to above present fairly,
in all material respects, the financial position of Advanced Aerodynamics &
Structures, Inc., at December 31, 1999, and the results of its operations and
its cash flows for each of the two years then ended and the period from January
26, 1990 (inception) through December 31, 1999, in conformity with accounting
principles generally accepted in the United States.

     The accompanying financial statements have been prepared assuming Advanced
Aerodynamics & Structures, Inc. will continue as a going concern. As more fully
described in Note 2, the Company has incurred recurring losses and its working
capital at December 31, 1999 has been substantially depleted. These conditions
raise substantial doubt about the Company's ability to continue as a going
concern. Management's plans in regard to these matters are also described in
Note 2. The 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 outcome
of this uncertainty.

   Company is in the development stage of designing a multi-purpose light
   aircraft. The present design of the aircraft is based on Pratt & Whitney-
   designed engines. Since its inception, the Company has been engaged primarily
   in research and development of its proposed aircraft the JETCRUZER 500, for
   commercial sale. The Company is in the process of obtaining its Federal
   Aviation Administration ("FAA") Type Certificate for technical revisions to
   its aircraft for commercial sale.

   During 1996 the Company successfully completed its  initial public offering
   of 6,900,000 units, including the exercise of the overallotment option. Each
   unit sold is composed on one share of Class A common stock one class A
   warrant and one class B warrant. The net proceeds of the offering of
   $30,411,000 were  used to  finance the continued development, manufacture and
   marketing of its product to achieve commercial viability.

2. FINANCIAL RESULTS AND LIQUIDITY

   The Company is currently in the process of developing their product and
   obtaining appropriate certification from the Federal Aviation
   Administration. To date, the Company has generated no sales revenue and none
   is projected until the Company can begin commercial production of their
   product and. the certification process is complete Prior to commencing
   commercial sales, the Company will need to, among other things, complete the
   development of the JETCRUZER 500 and obtain the requisite regulatory
   approvals. The Company incurred program development costs to date of
   approximately $30,000,000 and has recorded a cumulative net loss of
   $50,412,000. Based upon the Company's current development spending levels,
   current working capital is insufficient to meet the Company's needs over the
   current year.

   The Company's management team has been developing a financial plan to address
   its working capital requirements. As discussed in Note 4, the Company entered
   into a subscription agreement for the sale of up to $10,000,000 of 5%
   Cumulative Convertible Series A Preferred Stock, of which the Company
   received net proceeds of $4,550,000. Additionally, The Company signed a
   letter of intent to sell and leaseback manufacturing equipment. This
   transaction will generate an additional $1,000,000.

   Going forward, however, significant amounts of additional cash will be needed
   to continue the Company's development activities and ultimately production.
   The remaining $5,000,000 in Preferred Stock funding will not occur until
   certain criteria have been met, including passing the pressurization test for
   the fuselage structure and completion of the registration of 200% of the
   Common Stock underlying the Convertible Preferred Stock. It is anticipated
   that the remaining proceeds will be received in two installments; $2 million
   in the second quarter and the final $3 million in the third quarter.
   Additionally, the commencement of production and the collection of progress
   payments starting in the third quarter is imperative to the success of
   managements' financial plan to meet its working capital requirements.
   There can be no assurances that the current timetable for completion of the
   development and certification of the aircraft will not be delayed beyond the
   current fiscal year.

   While there is no assurance that additional financing will be available, the
   Company's management believes that it has developed a financial plan that, if
   executed successfully, will substantially improve the Company's ability to
   meet its working capital requirements and ultimate production.

   The Company's Independent Auditors have included a "going concern" emphasis
   paragraph in their audit report accompanying the 1999 financial statements.
   The paragraph states that the recurring losses and working capital depletion
   of Advanced Aerodynamics & Structures, Inc. raises substantial doubt about
   the Company's ability to continue as a going concern and cautions that the
   financial statements do not include any adjustments that might result from
   the outcome of this uncertainty.

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

   RESEARCH AND DEVELOPMENT COSTS

   All costs incurred in the design, testing, and certification of aircraft
   being developed by the Company (including cost of in-process research and
   development acquired) are expensed as incurred.

   PREOPERATING COSTS

   Preoperating costs are expensed as incurred.

   ADVERTISING EXPENSE

   Advertising costs are expensed as incurred. Advertising expense was $97,000
   and $75,000 for the years ended December 31, 1999 and 1998, respectively.

   CASH EQUIVALENTS

   Cash equivalents represent short-term, highly liquid instruments that have
   original maturities of three months or less and are readily convertible to
   cash. Such investments consist primarily of a money market account, short
   term government funds, and short term commercial paper. The cost of such
   investments approximates fair value at December 31, 1999.

   CONCENTRATION OF CREDIT RISK

   Financial instruments, which potentially subject the Company to
   concentrations of credit risk, consist principally of cash, cash equivalents
   and short term investments. The Company maintains its financial instruments
   with major financial institutions. At times, cash balances held by financial
   institutions were in excess of federal limits. The Company by policy, limits
   the amount of credit exposure to anyone financial institution, and does not
   consider itself to have any significant concentrations of credit risk.

   FAIR VALUE OF FINANCIAL INSTRUMENTS

   The fair value of substantially all financial instruments of the Company
   approximates their carrying value in the aggregate due to their short-term
   maturity and/or prevailing market interest rates.

   SHORT TERM INVESTMENTS
   The Company's investment strategies consider safety of principal,
   availability of funds and maximum return on investment.

   Management determines the appropriate classification of debt securities at
   the time of purchase and reevaluates such designation as of each balance
   sheet date. Debt securities are classified as held-to-maturity when the
   Company has the positive intent and ability to hold the securities to
   maturity. Held-to-maturity securities are stated at amortized cost, adjusted
   for amortization of premiums and accretion of discounts to  maturity. Such
   amortization is included in investment income. Interest on  securities
   classified as held-to-maturity is included in investment income.

   Debt securities for which the Company does not have the intent or ability to
   hold to maturity are classified as "available for sale"  and are reported at
   their fair market value as determined by the quoted market  price. During the
   year ended December 31, 1999, the Company incurred $32,000 in gross
   unrealized losses on debt securities classified as "available for sale",
   which has been reported as comprehensive loss in the statement of
   shareholders' equity. The tax effect of these losses is immaterial to the
   financial statements.

                   NOTES TO FINANCIAL STATEMENTS (Continued)

   PROPERTY, PLANT AND EQUIPMENT

   Property, plant and equipment are stated at cost and are depreciated using
   the straight-line method over their estimated useful lives of 5-10 years  for
   machinery and equipment, 3-5 years for office furniture and equipment and 18
   years for the building acquired under a capital lease. Leasehold improvements
   are amortized over the shorter of their estimated useful lives or the term of
   the lease. Included in depreciation expense is the amortization of assets
   acquired under capital leases.

   INCOME TAXES

   Income taxes are accounted for under an asset and liability approach that
   requires the recognition of deferred tax assets and liabilities for the
   expected future tax consequences of events that have been recognized in the
   Company's financial statements or tax returns. A valuation allowance is
   established to reduce deferred tax assets if it is more likely than not that
   all or some portion of such deferred tax assets will not be realized.

   STOCK BASED COMPENSATION

   The Company grants stock options with an exercise price equal to at least the
   fair value of the stock at the date of grant as determined by the Board of
   Directors.

   The Company has elected to follow Accounting Principles Board Opinion No. 25,
   "Accounting for Stock Issued to Employees" (APB 25) and related
   Interpretations in accounting for its employee stock based compensation plans
   which is an inhinsic value based method.  Under APB 25, because the exercise
   price of the Company's employee stock options equals or exceeds the market
   price of the underlying stock on the date of grant, no compensation expense
   is recognized.

   ACCOUNTING  ESTIMATES

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

   ACCOUNTING PRONOUNCEMENTS

   In the current year, the Company adopted the provisions of Statement of
   Position (SOP) 98-1, Accounting For the Costs of Computer Software Developed
   For or Obtained For Internal Use.  SOP 98-1 requires the capitalization and
   amortization of qualified computer software for internal use. There has been
   no impact to the Company's earnings or financial position due to adoption of
   SOP 98-1.

   In April 1999, the AICPA issued SOP 98-5, "Reporting on the Costs of Start-
   up Activities," which is effective for fiscal years beginning after December
   15, 1999. SOP 98-5 provides guidance on the financial reporting of start-up
   cost and organization costs and require such costs to be expensed as
   incurred. Management believes that the adoption of SOP 98-5 will not have a
   material effect on the Company's financial statements.

   In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
   Instruments and Hedging Activities ."As amended, SFAS No. 133 establishes
   accounting and reporting standards for derivative instruments.  The effective
   date of the pronouncement was delayed to fiscal years beginning after June
   18, 2000 and is effective for interim periods in the year of adoption.   The
   statement requires that every derivative instrument be recorded in the
   balance sheet as either an asset or liability measured at its fair value, and
   that changes in the derivative's fair value be recognized currently in
   earnings unless specific hedge accounting criteria are met. Management
   believes that the adoption of SFAS No. 133 will not have

   a material effect on the Company's financial statements, because the Company
   does not have any derivative instruments as of December 31, 1999.

4. PREFERRED STOCK SUBSCRIPTION

   On March 6, 2000, the Company  received $4,550,000 in net proceeds related to
   an agreement to issue up to 100,000 shares of  5% Cumulative Convertible
   Series A Preferred Stock with a par value of $.0001 for the aggregated
   purchase price of $10 million and Common Stock Purchase Warrants to purchase
   Class A Common Stock at an above market price. For consideration received in
   the initial funding, the Company issued 50,000 shares of Preferred stock and
   650,000 Warrants and paid $450,000 in commissions and legal fees.
   Additionally, as consideration for the transaction a Special Warrant to
   purchase up to 25,000 shares Class A Common Stock was issued. The remaining
   $5,000,000 in funding will not occur until certain criteria have been met,
   including passing the pressurization test for the fuselage structure and
   completion of the registration of 200% of the Common Stock underlying the
   Convertible Preferred Stock. Terms for the Special Warrant are similar to the
   terms of the Warrants issued with the Preferred Stock.

   Holders of the Preferred Stock are entitled to receive cash dividends,
   payable quarterly and have preferential liquidation rights above all other
   issuances of common stock for an amount equal to the stated value.  The
   Preferred stock and unpaid dividends are convertible into shares of Common
   stock equal to an amount determined by the market value at the date of close
   of the common stock, adjusted for changes in the market price prior to the
   conversion.  The Preferred stockholders do not have voting rights.  The
   Warrants are callable in installments after the registration is effective.
   The Company has reserved 4,000,000 of its Class A Common Stock for the
   conversion of the Preferred Stock.

5. PROPERTY, PLANT AND EQUIPMENT

   Property and equipment consist of the following:


       Building                                               $ 9,800,000

                                                              ===========

   As described in note 13, the building is held under a capital lease.  In
   addition, included in office furniture and equipment and machinery and
   equipment are assets acquired under capital leases in the amount of $272,000
   and $33,000 respectively.

6  INCOME TAXES

   Deferred income taxes reflect the net tax effects of temporary differences
   between the carrying amounts of assets and liabilities for financial
   statements purposes and the amounts used for income tax purposes. Significant
   components of the Company's deferred tax liabilities and assets as of
   December 31, 1999 are as follows:

8.   RELATED PARTY TRANSACTIONS

     In 1995 and through August 1996, an officer of the Company made loans to
     the Company in the aggregate principal amount of $562,000 bearing interest
     at 12% per annum. In May 1996, $336,000 of such loans were converted into
     187,118 shares of Class B Common Stock and 374,236 shares each of Class E-1
     and Class E-2 Common Stock. The remaining $226,000 principal amount of
     these loans, together with accrued interest of $36,000, was repaid with the
     proceeds of bridge notes.

     On December 23, 1993, the Company entered into an agreement with a
     stockholder to convert advances from such stockholder aggregating
     $10,478,000 at that date into 584,074 shares of Class B Common Stock, and
     1,168,148 shares each of Class E-1 and Class E-2 Common Stock. The Company
     issued these shares in June 1996. Interest expense was not recorded on
     these advances subsequent to December 23, 1993 due to the intent to convert
     the advances into stockholders' equity. In 1994, the stockholder provided
     additional advances aggregating $250,000, which were converted into 13,937
     shares of Class B Common Stock and 27,873 shares each of Class E-1 and
     Class E-2 Common Stock in June 1996. Based on prevailing market rates,
     imputed interest of $11,000 in 1996, and $810,000 for the period from
     January 26, 1990 (inception) to December 31, 1996 on the advances was
     charged to expense and credited to additional paid-in capital.

     In May 1996, the Company entered into an employment agreement with the
     Company's President, which extends to April 30, 2004 and provides for an
     annual salary of $200,000. If the employment agreement is terminated by the
     Company without cause, the President may be entitled to receive up to
     eighteen months' salary as severance payment. In consideration of the
     termination of a previous employment agreement the Company issued 577,823,
     1,155,647 and 1,155,647 shares of Class B, Class E-1 and Class E-2 common
     stock, respectively, to the Company's President.

     Also in May 1996, an officer of the Company was awarded 17,460 shares of
     Class B Common Stock and 34,919 shares each of Class E-1 and Class E-2
     Common Stock for services rendered. Compensation cost of $31,000 was
     charged to expense in 1996 based on the fair value of the stock awarded by
     reference to an independent appraisal.

9.   COMMITMENTS AND CONTINGENCIES

     In the ordinary course of business, the Company is generally subject to
     claims, complaints, and legal actions. At December 31, 1999, the Company is
     not a party to any action which would have a material impact on its,
     financial condition, operations, or cash flows.

     The Company leases approximately 10 acres of land located on the Long Beach
     Airport in Long Beach, California. The lease commenced on January 14, 1998
     and has a term of 30 years with an option to renew for an additional 10
     year term. The lease also contains options to lease other airport
     properties. The current monthly rent under the lease is $7,400. The lease
     contains incremental increases which escalate the monthly rent to
     approximately $15,600 after 5 years. The aggregate minimum payments under
     the lease have been included in the table below.

     In addition, as described in Note 13; in May 1999 the Company entered into
     an agreement with a third party to sell its manufacturing and
     administrative facility and lease it back under a capital lease. The lease
     term is for 18 years plus an option to extend the lease for an additional
     10 years. Monthly payments under this lease are approximately $106,000 and
     will be adjusted annually, after the first year, for changes in the
     Consumer Price Index, subject to a maximum of 3%.

     Future minimum lease payments applicable to non-cancelable operating leases
     and capital leases as of December 31, 1999, are as follows:

     years ended December 31, 1999 and 1998, respectively.

10.  STOCKHOLDERS' EQUITY

     Upon formation of AASI, an aircraft prototype and related proprietary
     technology were contributed by Aerodynamics and Structures, Inc. ("ASI") in
     exchange for 2,500,764 AASI common shares with a fair value of $250,000. In
     connection with this exchange, the Company also assumed ASI's liabilities
     of approximately $400,000. Three other individuals contributed technical
     information in exchange for 1,113,740 AASI common shares with a fair value
     of $111,000. Such technology and prototype acquired were immediately
     expensed as in- process research and development. Finally, certain
     investors contributed $7,500,000 in cash in exchange for 7,500,000 shares
     of convertible preferred stock of AASI. ASI was subsequently liquidated and
     its sole asset, investment in AASI common shares, was distributed to ASI's
     stockholders. Upon reincorporation of the Company, the Company's
     aforementioned common and preferred shares were converted into
     approximately 619,588, 1,239,177 and 1,239,177 shares, respectively, of
     Class B, Class E-1 and Class E-2 Common Stock.

     The rights and privileges of holders of Class A, Class B, Class E-1 and
     Class E-2 Common Stock are substantially the same on a share-for-share
     basis, except that: (i) the holder of each outstanding share of Class A
     Common Stock is entitled to one vote and the holder of each outstanding
     share of Class B, Class E-1 and Class E-2 Common Stock is entitled to five
     votes;

                   NOTES TO FINANCIAL STATEMENTS (Continued)

     and (ii) Class B Common Stock cannot be transferred or sold for thirteen
     months following the effective date of the initial public offering, after
     which time the Class B Common Stock may be converted at any time at the
     option of the holder into one share of Class A Common Stock.

     In February of 1998 a shareholder of the Company converted 99,676 shares of
     Class B common Stock to 99,676 shares of Class A Common Stock. The
     conversion resulted in an increase in Class A Common Stock to 6,999,676 and
     a decrease in the number of outstanding shares of Class B Common Stock to
     1,900,324. This transaction had no impact on losses per common share as
     both classes of shares are included in the calculation of weighted average
     number of common stock outstanding.

     All shares of Class E-1 and Class E-2 Common Stock ("Performance Shares")
     are not transferable or assignable and may be converted into shares of
     Class B Common Stock in the event income before provision for income taxes,
     exclusive of any extraordinary earnings or losses, reaches certain targets
     over the next seven years, or if the market price of the Class A Common
     Stock reaches specified levels over the next three years. With respect to
     targeted earnings, Class E-1 Common Stock shares may be converted if pretax
     income $28.5 million in 2000, $36.0 million in 2001, $45.00 million in 2002
     and $56.0 million in 2003. Class E-2 Common Stock shares may be converted
     if pretax income exceeds, $35.6million in 2000, $45.0 million in 2001, $563
     million in 2002 or $69.5 million in 2003. With respect to market price
     levels, the Class E-1 Common Stock shares may be converted if, commencing
     18 months after December 3, 1996 and ending 36 months thereafter, the bid
     price of the Company's Class A Common Stock averages $18.50 per share for
     30 consecutive business days. Class E-2 Common Stock shares may be
     converted if commencing 18 months after December 3, 1996 and ending 36
     months thereafter, the bid price of the Company's Class A Common Stock
     averages in excess of $23.00 for 30 consecutive business days. All
     Performance Shares that have not been converted by March 31, 2004 may be
     redeemed by the Company for $.01 per share. For accounting purposes, the
     Performance Shares are treated in a manner similar to a variable stock
     option award. As a consequence, a compensation charge will be recorded in
     an amount equal to the then fair value of any Performance Shares that are
     ultimately converted into Class B Common Stock.

     Upon the closing of the Initial Public Offering, the Company granted to the
     Underwriter Unit Purchase Option to purchase up to 600,000 Units. The Units
     issuable upon exercise of the Unit Purchase Option will, when so issued, be
     identical to the Units. The Unit Purchase Option cannot be transferred,
     sold, assigned or hypothecated for three years, except to any officer of
     the Underwriter or member of the selling group or their officers. The Unit
     Purchase Option is exercisable during the two-year period commencing three
     years from December 6, 1996 at an exercise price of $6.50 per Unit (130% of
     the initial public offering price) subject to adjustment under certain
     circumstances. The holders of the Unit Purchase Option have certain demand
     and piggyback registration rights.

     The Company has reserved approximately 39,400,000 shares of Class A Common
     Stock for future issuance for the following conversions: 1,900,000 shares
     issuable upon the conversion of Class B common stock currently outstanding;
     8,000,000 shares issuable upon the conversion of Class B common stock
     should the 4,000,000 shares of Class E-1 and E-2 common stock, respectively
     be converted into shares of Class B common stock; 27,700,000 shares
     issuable upon the exercise of purchase warrants; and 1,800,000 shares
     issuable upon the exercise of a 600,000 unit purchase option by the
     Company's underwriter. In addition, the Company has reserved 8,000,000
     shares of Class B common stock for future issuance upon the conversion of
     4,000,000 shares of Class E-1 and E-2 common stock respectively.

11.  WARRANTS

     The Class A Warrants entitle the holder to purchase one share of Class A
     Common Stock and one Class B Warrant. Each Class B Warrant entitles the
     holder to purchase one share of Class A Common Stock. Class A Warrants and
     Class B Warrants may be exercised at an exercise price of $6.50 and $8.75,
     respectively, at anytime until December 3, 2001. Currently Class A Warrants
     are subject to redemption by the Company, upon 30 days written notice, at a
     price of $.05 per Warrant, if the average closing bid price of the Class A
     Common Stock for any 30 consecutive trading days ending within 15 days of
     the date on which the notice of redemption is given shall have exceeded
     $12.00 per share. Currently Class B Warrants are subject to redemption by
     the Company upon 30 days written notice, at a price of $.05 per Warrant, if
     the average closing bid price of the Class A Common Stock for any 30
     consecutive trading days ending within 15 days of the date on which the
     notice of redemption

     Upon closing of the public offering previously issued bridge warrants were
     converted into one Class A Warrant ("Public Warrant") which is identical in
     all respects to the Class A Warrant. The fair value of the Bridge Warrants
     ($473,000), together with the cost of issuance (approximately $805,000),
     has been treated as additional interest expense over the term of the Bridge
     Notes.

12.  STOCK OPTIONS

     In July 1996, the Company's Board of Directors approved the Stock Option
     Plan (the "Plan"). The Plan provides for the grant of incentive and non-
     qualified stock options to certain employees, officers, directors,
     consultants, and agents of the Company. In March 1998, the Board of
     Directors amended the Plan by authorizing the Company the ability to grant
     additional options for up to 500,000 shares of Class A Common Stock. Under
     the Plan, the Company may grant options with respect to a total of
     1,000,000 shares of the Class A Common Stock. The options are to be granted
     at not less than fair market value, vest in equal annual installments over
     five years and may be exercised for a period of one to ten years as
     determined by the Board of Directors.

     Had the Company accounted for stock options granted in 1998 and 1999 using
     the fair value method at the date of grant as prescribed by Statement of
     financial Accounting Standards No. 123, additional compensation expense
     would have been recorded and the pro form effects would have been as
     follows:

<TABLE>

</TABLE>

     The fair value for these options was estimated at the date of grant using a
     Black-Scholes option pricing model with the following weighted-average
     assumptions: risk-free interest rates of 5.02% and 6.81% for 1998 and 1999,
     respectively; dividend yields of 0% for 1998 and 1999; volatility factors
     of the expected market price of the Company's common stock of .878 and .863
     for 1998 and 1999, respectively; and a weighted average expected life of
     the option of 10 years for both 1998 and 1999, respectively.

                   NOTES TO FINANCIAL STATEMENTS (Continued)

     The Black-Scholes option valuation model was developed for use in
     estimating the fair value of traded options which have no vesting
     restrictions and are fully transferable. In addition, option valuation
     models require the input of highly subjective assumptions including the
     expected stock price volatility. Because the Company's employee stock
     options have characteristics significantly different from those of traded
     options, and because changes in the subjective input assumptions can
     materially affect the fair value estimate, in management's opinion, the
     existing models do not necessarily provide a reliable single measure of the
     fair value of employee stock options.

     The weighted average fair value of options granted during 1998 and 1999 was
     $.73 and $2.22, per option, respectively. The weighted average exercise
     price for 1997 and 1999 was $5.00. The weighted average remaining
     contractual life of options outstanding is 8.75 years and 8.06 years for
     1998 and 1999, respectively.

     At December 31, 1999, options to purchase 175,000 shares of Class A Common
     Stock were available for future grants and 588,000 shares of Class A Common
     Stock were reserved for the exercise of options. Transactions under the
     Plan during the year ended December 31, 1998 and 1999 are summarized as

     On August 5, 1997, the Company entered into a loan agreement in connection
     with industrial development bonds (IDB) issued by the California Economic
     Development financing Authority. The Company has established in the
     trustee's favor a bank letter of credit for the principle amount of
     $8,500,000 plus 45 days accrued interest on the bonds, which is secured by
     $8,500,000 of Company restricted cash. The bonds mature August 1, 2027 at
     which time all outstanding amounts become due and payable. The Company has
     used the proceeds for the IDBs to finance the construction and installation
     of the 200,000 square foot manufacturing facility and related manufacturing
     equipment which the Company moved into on November 16, 1998. On June 1,
     1999, the Company retired all the industrial development bonds using the
     restricted cash previously held as security for the IDB.

                   NOTES TO FINANCIAL STATEMENTS (Continued)

14.  SALE AND LEASEBACK TRANSACTION

     Pursuant to an Agreement dated May 19, 1999, the Company sold to AP-Long
     Beach Airport LLC its leasehold interest in real property located at 3205
     Lakewood Boulevard, Long Beach, California, together with the manufacturing
     hangar facility (approximately 205,000 square feet) and finished office
     space (approximately 22,000 square feet) owned by the company
     (collectively, the "Property". The cash sales price was $9,800,000.

     As part of this transaction, the Company and AP-Long Beach Airport LLC
     entered into an agreement to sublease the land to the Company subject to
     the terms at the original land lease agreement which was assigned to AP
     Long Beach Airport LLC, and lease the manufacturing hangar facility and
     finished office space to the Company for term of 18 years. The $246,000
     deferred gain on the sale of the facility is being amortized over the 18
     year lease term.

15.  BENEFIT PLAN

     The Company has a 401(k) savings plan and a profit sharing plan, covering
     substantially all full time employees. The Company may make discretionary
     contributions, under the profit sharing plan, as authorized by the Board of
     Directors. The Company has not made any profit sharing contributions to the
     Plan.

16.  PER SHARE INFORMATION

     In February 1997, the FASB issued Statement 128, talks "Earnings per
     Share", It replaces the presentation of primary Earnings per share with a
     presentation of basic earnings per share which excludes any dilutive
     effects of options, warrants and convertible securities, and is computed by
     dividing income available to common stockholders by the weighted-average
     number of common shares outstanding for the period. The statement is
     effective for financial statements issued for periods ending after December
     15, 1997. Previously reported net losses per share were reported based on
     weighted average common stock outstanding and therefore the amounts are the
     same as under FAS No. 128.

     The following table sets forth the computation of basic loss per share:

Warrants is binding upon the Company and enforceable, except as otherwise
described in this Subscription Agreement, regardless of the dilution such
issuance may have on the ownership interests of other shareholders of the
Company.

              -------------

              ----------------------
affiliates, nor any person acting on its or their behalf, has directly or
indirectly made any offers or sales of any security or solicited any offers to
buy any security under circumstances that would cause the offering of the
Securities pursuant to this Agreement to be integrated with prior offerings by
the Company for purposes of the 1933 Act or any applicable stockholder approval
provisions, including, without limitation, under the rules and regulations of
The NASDAQ National Market ("NASDAQ National Market"), as applicable, nor will
the Company or any of its affiliates or subsidiaries take any action or steps
that would cause the offering of the Securities to be integrated with other

              -------

written notice from NASDAQ that its Common Stock will be delisted from NASDAQ or
that the Common Stock does not meet all requirements for the continuation of
such listing.

              ------------------------------

resale subject to an effective registration statement after the Securities are
registered under the Act.  The Company agrees to cooperate with the Subscriber

provide legal opinions necessary to allow such resales provided the Company and
its counsel receive reasonably requested representations from the Subscriber and
selling broker, if any.

Agreement to be entered into by the Company, Subscriber and an Escrow Agent. The
Company will also issue and deliver to the Placement Agents as additional
compensation Placement Warrants designated on Schedule B hereto. The Commissions
and Placement Warrants will be issued to the Placement Agents only when, as, and

               ------------------------
the Subscriber as follows:

               (a)  The Company will advise the Subscriber, promptly after it
receives notice of issuance by the Securities and Exchange Commission, any state
securities commission or any other regulatory authority of any stop order or of
any order preventing or suspending any offering of any securities of the
Company, or of the suspension of the qualification of the common stock of the

<PAGE>

          (b) The Company shall promptly secure the listing of the Company
Shares, and Common Stock issuable upon the exercise of the Warrants and
Placement Warrants upon each national securities exchange, or automated
quotation system, if any, upon which shares of common stock are then listed
(subject to official notice of issuance) and shall maintain such listing so long
as any other shares of common stock of the Company shall be so listed. The
Company will use its best efforts to maintain the listing and trading of its
Common Stock on NASDAQ National Market, and will comply in all respects with the
Company's reporting, filing and other obligations under the bylaws or rules of
the National Association of Securities Dealers ("NASD") and such exchanges, as
applicable. The Company will provide the Subscriber copies of all notices it
receives notifying the Company of the actual delisting of the Common Stock on
any exchange or quotation system on which the Common Stock is listed.

          (c) The Company shall notify the SEC, NASD and applicable state
authorities, in accordance with their requirements, of the transactions
contemplated by this Agreement, and shall take all other necessary action and
proceedings as may be required and permitted by applicable law, rule and
regulation, for the legal and valid issuance of the Securities to the Subscriber
and Placement Agents and promptly provide copies thereof to Subscriber.

          (d) Until at least two (2) years after the effectiveness of the
Registration Statement on Form SB-2 or such other Registration Statement
described in Section 10.1(iv) hereof, the Company will (i) cause its Common
Stock to continue to be registered under Sections 12(b) or 12(g) of the Exchange
Act, (ii) comply in all respects with its reporting and filing obligations under
the Exchange Act, (iii) comply with all reporting requirements that is
applicable to an issuer with a class of Shares registered pursuant to Section

take any action or file any document (whether or not permitted by the Act or the
Exchange Act or the rules thereunder) to terminate or suspend such registration
or to terminate or suspend its reporting and filing obligations under said Acts
until the later of (y) two (2) years after the effective date of the
Registration Statement on Form SB-2 or such other Registration Statement
described in Section 10.1(iv) hereof, or (z) the sale by the Subscribers and
Placement Agents of all the Company Shares issuable by the Company pursuant to
this Agreement.  Until at least two (2) years after the Warrants and Placement
Warrants have been exercised, the Company will use its commercial best efforts
to continue the listing or trading of its Common Stock on NASDAQ National Market
and will comply in all respects with the Company's reporting, filing and other
obligations under the bylaws or rules of the NASD and NASDAQ.

          (e) The Company and Subscriber agree that until the Company either
obtains shareholder approval of the issuance of the Securities and Put
Securities (as defined herein), or an exemption from NASDAQ's corporate
governance rules as they may apply to the Securities and Put Securities, and an
opinion of counsel reasonably acceptable to Subscriber that NASDAQ's corporate
governance rules do not conflict with nor may result in a delisting of the
Company's common stock from the NASDAQ National Market upon the conversion of
the Preferred Stock and exercise of the Warrants and Placement Warrants and
Conversion of the Put Stock and exercise of the Put Warrants and Put Placement
Warrants (the "Approval"), the Subscriber may not receive upon conversion of the
Preferred Stock and exercise of the Warrants nor may the Placement Agents

                                       8
<PAGE>

receive upon exercise of the Placement Warrants more than the number of Company
Shares designated on the signature page hereof and on Schedule B hereof
("Section 7.1(e) Shares") upon conversion of the Preferred Stock and/or exercise
of the Warrants and Placement Warrants.  The Company represents that this number
together with the aggregate of such amounts designated for all investors in the
initial $5,000,000 offering to which this Subscription Agreement relates, and
Common Stock issuable upon exercise of the Warrants and Placement Warrants is
not greater than 19.9% of the shares of Company's common stock outstanding on
the Closing Date.  The Company covenants to obtain the Approval required
pursuant to the NASDAQ's corporate governance to allow conversion of all the
Preferred Stock and dividends thereon and exercise of all the Warrants and
Placement Warrants.  The Company further covenants to file the preliminary proxy
statement relating to the Approval with the Commission on or before forty-five
days after the Closing Date ("Proxy Filing Date").  The Company further
covenants to obtain the Approval no later than ninety days after the Closing
Date ("Approval Date").  The Company's failure to file the proxy on or before
the Proxy Filing Date or the Company's failure to obtain the Approval on or
before the Approval Date (either being an "Approval Default") shall be deemed an
Event of Default pursuant to Section 8 of the Certificate of Designation, but
only to the extent the Preferred Stock, and dividends thereon that may not be
converted due to the Company's failure to obtain such Approval.

               (f) The Company undertakes to use the proceeds of the
Subscriber's funds for working capital purposes and expenses of this offering.

          7.2. Covenant of the Subscriber.  The Subscriber covenants that the
               --------------------------
Subscriber nor any of its affiliates will not engage in short sales of the
common stock of the Company at a time when the last reported bid of the common
stock as reported by NASDAQ National Market is less than $7.00 per share.

          8.   Covenants of the Company and Subscriber Regarding
               -------------------------------------------------
               Idemnifications.
               ----------------

               (a) The Company agrees to indemnify, hold harmless, reimburse and
defend Subscriber against any claim, cost, expense, liability, obligation, loss
or damage (including reasonable legal fees) of any nature, incurred by or
imposed upon Subscriber which results, arises out of or is based upon (i) any
misrepresentation by Company or breach of any warranty by Company in this
Agreement or in any Exhibits or Schedules attached hereto, or Reports or other
Written Information; or (ii) any breach or default in performance by Company of
any covenant or undertaking to be performed by Company hereunder, or any other
agreement entered into by the Company and Subscribers relating hereto.

               (b) Subscriber agrees to indemnify, hold harmless, reimburse and
defend the Company at all times against any claim, cost, expense, liability,
obligation, loss or damage (including reasonable legal fees) of any nature,
incurred by or imposed upon the Company which results, arises out of or is based
upon (a) any misrepresentation by Subscriber in this Agreement or in any
Exhibits or Schedules attached hereto; or (b) any breach or default in
performance by Subscriber of any covenant or undertaking to be performed by
Subscriber hereunder, or any other agreement entered into by the Company and
Subscribers relating hereto.

                                       9
<PAGE>

               (c) The procedures set forth in Section 10.6 shall apply to the
indemnifications set forth in Sections 8(a) and 8(b) above.

          9.1. Conversion/Liquidated Damages.
               -----------------------------

               (a) The Preferred Stock and accrued dividends will be convertible
according to the procedure set forth in the Certificate of Designation.

               (b) The Company understands that a delay in the delivery of the
Company Shares after Conversion, and delivery of Preferred Stock certificates
representing the unconverted balance of a Preferred Stock certificate tendered
for conversion beyond the date described for such delivery set forth in the
Certificate of Designation, or late delivery of a Mandatory Redemption Payment
(as defined herein), as the case may be, (each of the foregoing a "Delivery
Date") could result in economic loss to the Subscriber.  As compensation to the
Subscriber for such loss, the Company agrees to pay late payments to the
Subscriber for late delivery of Shares upon Conversion and late delivery of a
Preferred Stock certificate for the unconverted portion of Preferred Stock or
late delivery of a Mandatory Redemption Payment, in the amount of $100 per
business day after the Delivery Date for each $10,000 of Stated Value of
Preferred Stock being converted and Preferred Stock certificate remaining
undelivered or Mandatory Redemption Payment not paid.  The Company shall pay any
payments incurred under this Section in immediately available funds upon demand.
Furthermore, in addition to any other remedies which may be available to the
Subscriber, in the event that the Company fails for any reason to effect
delivery of the Shares within three business days after the Delivery Date, the
Subscriber will be entitled to revoke the relevant Notice of Conversion by
delivery of a notice of revocation to the Company whereupon the Company and the
Subscriber shall each be restored to their respective positions immediately
prior to the delivery of such notice of revocation, except that late payment
charges described above shall be payable through the date notice of revocation
is given to the Company.

               (c) Nothing contained herein or in any document referred to
herein or delivered in connection herewith shall be deemed to establish or
require the payment of a rate of interest or other charges in excess of the
maximum permitted by applicable law. In the event that the rate of interest or
dividends required to be paid or other charges hereunder exceed the maximum
permitted by such law, any payments in excess of such maximum shall be credited
against amounts owed by the Company to the Subscriber and thus refunded to the
Company.

          9.2. Mandatory Redemption.  In the event the Company may not issue
               --------------------
Shares on a Delivery Date because such issuance and delivery would be contrary
to NASDAQ's Corporate Governance Rules, or after the occurrence and during the
pendency of an Approval Default, or for any other reason (except in relation to
the Shares not deliverable pursuant to Section 9.3 of this Subscription
Agreement), then at the Subscriber's election, the Company must pay to the
Subscriber on the Delivery Date a sum of money determined by the greater of (i)
multiplying the Stated Value of Preferred Stock not convertible by 110% together
with accrued but unpaid dividends thereon; or (ii) the closing bid price of the
common stock as reported by the NASDAQ National Market or the principal exchange
or market where traded for the Delivery Date multiplied by the amount of Shares
not deliverable, together with accrued but unpaid dividends thereon, ("Mandatory
Redemption

                                       10
<PAGE>

Payment"). The Mandatory Redemption Payment must be received by the Subscriber
on the same date as the Company Shares otherwise deliverable. Upon receipt of
the Mandatory Redemption Payment, the corresponding Preferred Stock will be
cancelled and no longer outstanding, and if the Holder is in possession of the
corresponding Preferred Stock, same will be returned to the Company.

          9.3. Maximum Conversion.  The Company and Subscriber shall not be
               ------------------
entitled to convert on a Conversion Date of that amount of the Preferred Stock
in connection with that number of shares of Common Stock which would be in
excess of the sum of (i) the number of shares of Common Stock beneficially owned
by the Subscriber and its affiliates on a Conversion Date, and (ii) the number
of shares of Common Stock issuable upon the conversion of the Preferred Stock
with respect to which the determination of this proviso is being made on a
Conversion Date, which would result in beneficial ownership by the Subscriber
and its affiliates of more than 9.99% of the outstanding shares of Common Stock
of the Company.  For the purposes of the proviso to the immediately preceding
sentence, beneficial ownership shall be determined in accordance with Section
13(d) of the Securities Exchange Act of 1934, as amended, and Regulation 13d-3
thereunder, except as otherwise provided in clause (i) of such proviso.  The
Subscriber may revoke the restriction described in this paragraph upon 75 days
prior notice to the Company.  The Subscriber may allocate which of the equity of
the Company deemed beneficially owned by the Subscriber shall be included in the
9.9% amount described above and which shall be allocated to the excess above
9.99%.

          9.4. Injunction - Posting of Bond.  In the event a Subscriber shall
               ----------------------------
elect to convert Preferred Stock and/or accrued dividends, the Company may not
refuse conversion based on any claim that such Subscriber or any one associated
or affiliated with such Subscriber has been engaged in any violation of law, or
for any other reason unless, an injunction from a court, on notice, restraining
and or enjoining conversion of all or part of said Preferred Stock and/or
dividends shall have been sought and obtained and the Company posts a surety
bond for the benefit of such Subscriber in the amount of 150% of the amount of
the stated value of the Preferred Stock which is subject to the injunction,
which bond shall remain in effect until the completion of arbitration/litigation
of the dispute and the proceeds of which shall be payable to such Subscriber to
the extent it obtains judgment.

          9.5. Buy-In.  In addition to any other rights available to the
               ------
Subscriber, if the Company fails to deliver to the Subscriber Company Shares
issuable upon conversion of Preferred Stock and/or dividends by the Delivery
Date and if after the Delivery Date the Subscriber purchases (in an open market
transaction or otherwise) shares of common stock to deliver in satisfaction of a
sale by such Subscriber of the Company Shares which the Subscriber anticipated
receiving upon such conversion (a "Buy-In"), then the Company shall pay in cash
to the Subscriber (in addition to any remedies available to or elected by the
Subscriber) the amount by which (A) the Subscriber's total purchase price
(including brokerage commissions, if any) for the shares of common stock so
purchased exceeds (B) the aggregate stated value of the Preferred Stock for
which such conversion was not timely honored, together with interest thereon at
a rate of 15% per annum, accruing until such amount and any accrued interest
thereon is paid in full (which amount shall be paid as liquidated damages and
not as a penalty).  For example, if the Subscriber purchases shares of common
stock having a total purchase price of $11,000 to cover a Buy-In with respect to
an attempted conversion of $10,000 of stated value of Preferred Stock and/or
dividends, the Company

                                       11
<PAGE>

shall be required to pay the Subscriber $1,000, plus interest. The Subscriber
shall provide the Company written notice indicating the amounts payable to the
Subscriber in respect of the Buy-In.

          10.1.  Registration Rights.  The Company hereby grants the following
                 -------------------
registration rights to holders of the Securities.

                 (i)  On one occasion, for a period commencing 61 days after the
Closing Date, but not later than three years after the Closing Date, the
Company, upon a written request therefor from any record holder or holders of
more than 50% of the aggregate of the Company's Shares issued and issuable upon
Conversion of the Preferred Stock issued in the Company's offering of up to
$5,000,000 of stated value of Preferred Stock on the same terms and conditions
as in this Subscription Agreement (the Securities and securities issued or
issuable by virtue of ownership of the Securities, including the Put Securities,
are the "Registrable Securities"), shall prepare and file with the SEC a
registration statement under the Act covering the Registrable Securities which
are the subject of such request, unless such Registrable Securities are the
subject of an effective registration statement. In addition, upon the receipt of
such request, the Company shall promptly give written notice to all other record
holders of the Registrable Securities that such registration statement is to be
filed and shall include in such registration statement Registrable Securities
for which it has received written requests within 10 days after the Company
gives such written notice. Such other requesting record holders shall be deemed
to have exercised their demand registration right under this Section 10.1(i). As
a condition precedent to the inclusion of Registrable Securities, the holder
thereof shall provide the Company with such information as the Company
reasonably requests. The obligation of the Company under this Section 10.1(i)
shall be limited to one registration statement.

                 (ii) If the Company at any time proposes to register any of its
securities under the Act for sale to the public, whether for its own account or
for the account of other security holders or both, except with respect to
registration statements on Forms S-4, S-8 or another form not available for
registering the Registrable Securities for sale to the public, provided the
Registrable Securities are not otherwise registered for resale by the Subscriber
or Holder pursuant to an effective registration statement, each such time it
will give at least 30 days' prior written notice to the record holder of the
Registrable Securities of its intention so to do. Upon the written request of
the holder, received by the Company within 30 days after the giving of any such
notice by the Company, to register any of the Registrable Securities, the
Company will cause such Registrable Securities as to which registration shall
have been so requested to be included with the securities to be covered by the
registration statement proposed to be filed by the Company, all to the extent
required to permit the sale or other disposition of the Registrable Securities
so registered by the holder of such Registrable Securities (the "Seller"). In
the event that any registration pursuant to this Section 10.1(ii) shall be, in
whole or in part, an underwritten public offering of common stock of the
Company, (i) Seller shall enter into the underwriting agreement with the
underwriter, and (ii) the number of shares of Registrable Securities to be
included in such an underwriting may be reduced by the managing underwriter if
and to the extent that the Company and the underwriter shall reasonably be of
the opinion that such inclusion would adversely affect the marketing of the
securities to be sold by the Company therein; provided, however, that the
Company shall notify the Seller in writing of any such reduction.
Notwithstanding the forgoing provisions, the Company may

                                       12
<PAGE>

withdraw any registration statement referred to in this Section 10.1(ii) without
thereby incurring any liability to the Seller.

          (iii) If, at the time any written request for registration is
received by the Company pursuant to Section 10.1(i), the Company has determined
to proceed with the actual preparation and filing of a registration statement
under the 1933 Act in connection with the proposed offer and sale for cash of
any of its securities for the Company's own account, such written request shall
be deemed to have been given pursuant to Section 10.1(ii) rather than Section
10.1(i), and the rights of the holders of Registrable Securities covered by such
written request shall be governed by Section 10.1(ii) except that the Company or
underwriter, if any, may not withdraw such registration or limit the amount of
Registrable Securities included in such registration.

          (iv)  The Company shall file with the Commission within 60 days of the
Closing Date (the "Filing Date"), and use its reasonable commercial efforts to
cause to be declared effective a Form SB-2 registration statement (or such other
form that it is eligible to use) within 90 days of the Closing Date in order to
register the Registrable Securities for resale and distribution under the Act.
The registration statement described in this paragraph must be declared
effective by the Commission within 120 days of the Closing Date (as defined
herein) ("Effective Date").  The Company will register not less than a number of
shares of Common Stock in the aforedescribed registration statement that is
equal to 200% of the Company Shares issuable at the Conversion Price that would
be in effect on the Closing Date or the date of filing of such registration
statement, whichever is greater, assuming the conversion of all the Preferred
Stock and Put Stock set forth in the signature page hereto, and one share of
common stock for each common share issuable upon exercise of the Warrants,
Placement Warrants, Put Warrants and Put Commission Warrants.  The Registrable
Securities shall be reserved and set aside exclusively for the benefit of the
Subscriber and Placement Agents, as the case may be, and not issued, employed or
reserved for anyone other than the Subscriber and Placement Agents.  Such
registration statement will be promptly amended or additional registration
statements will be promptly filed by the Company as necessary to register
additional Company Shares to allow the public resale of all Common Stock
included in and issuable by virtue of the Registrable Securities.  No securities
of the Company other than the Registrable Securities will be included in the
registration statement described in this Section 10.1(iv).

          10.2. Registration Procedures. If and whenever the Company is
                -----------------------
required by the provisions hereof to effect the registration of any shares of
Registrable Securities under the Act, the Company will, as expeditiously as
possible:

                (a) prepare and file with the Commission a registration
statement with respect to such securities and use its best efforts to cause such
registration statement to become and remain effective for the period of the
distribution contemplated thereby (determined as herein provided), and promptly
provide to the holders of Registrable Securities copies of all filings and
Commission letters of comment;

                (b) prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective
until the latest of: (i) six months after the exercise period of the Warrants
and Placement Warrants; or (ii) two years after the Closing Date, and

                                       13
<PAGE>

comply with the provisions of the Act with respect to the disposition of all of
the Registrable Securities covered by such registration statement in accordance
with the Seller's intended method of disposition set forth in such registration
statement for such period;

                 (c) furnish to the Seller, and to each underwriter if any, such
number of copies of the registration statement and the prospectus included
therein (including each preliminary prospectus) as such persons reasonably may
request in order to facilitate the public sale or their disposition of the
securities covered by such registration statement;

                 (d) use its best efforts to register or qualify the Seller's
Registrable Securities covered by such registration statement under the
securities or "blue sky" laws of such jurisdictions as the Seller and in the
case of an underwritten public offering, the managing underwriter shall
reasonably request, provided, however, that the Company shall not for any such
purpose be required to qualify generally to transact business as a foreign
corporation in any jurisdiction where it is not so qualified or to consent to
general service of process in any such jurisdiction;

                 (e) list the Registrable Securities covered by such
registration statement with any securities exchange on which the Common Stock of
the Company is then listed;

                 (f) immediately notify the Seller and each underwriter under
such registration statement at any time when a prospectus relating thereto is
required to be delivered under the Act, of the happening of any event of which
the Company has knowledge as a result of which the prospectus contained in such
registration statement, as then in effect, includes an untrue statement of a
material fact or omits to state a material fact required to be stated therein or
necessary to make the statements therein not misleading in light of the
circumstances then existing;

                 (g) make available for inspection by the Seller, any
underwriter participating in any distribution pursuant to such registration
statement, and any attorney, accountant or other agent retained by the Seller or
underwriter, all publicly available, non-confidential financial and other
records, pertinent corporate documents and properties of the Company, and cause
the Company's officers, directors and employees to supply all publicly
available, non-confidential information reasonably requested by the seller,
underwriter, attorney, accountant or agent in connection with such registration
statement.

          10.3.  Provision of Documents.
                 ----------------------

                    (a) At the request of the Seller, provided a demand for
registration has been made pursuant to Section 10.1(i) or a request for
registration has been made pursuant to Section 10.1(ii), the Registrable
Securities will be included in a registration statement filed pursuant to this
Section 10.

                    (b) In connection with each registration hereunder, the
Seller will furnish to the Company in writing such information and
representation letters with respect to itself and the proposed distribution by
it as reasonably shall be necessary in order to assure compliance with federal
and applicable state securities laws. In connection with each registration
pursuant to Section

                                       14
<PAGE>

10.1(i) or 10.1(ii) covering an underwritten public offering, the Company and
the Seller agree to enter into a written agreement with the managing underwriter
in such form and containing such provisions as are customary in the securities
business for such an arrangement between such underwriter and companies of the
Company's size and investment stature.

          10.4.  Non-Registration Events.  The Company and the Subscriber agree
                 -----------------------
that the Seller will suffer damages if any registration statement required under
Section 10.1(i) or 10.1(ii) above is not filed within 60 days after request by
the Holder and not declared effective by the Commission within 120 days after
such request [or the Filing Date and Effective Date, respectively, in reference
to the Registration Statement on Form SB-2 or such other form described in
Section 10.1(iv)], and maintained in the manner and within the time periods
contemplated by Section 10 hereof, and it would not be feasible to ascertain the
extent of such damages with precision.  Accordingly, if (i) the Registration
Statement described in Sections 10.1(i) or 10.1(ii) is not filed within 60 days
of such request, or is not declared effective by the Commission on or prior to
the date that is 120 days after such request, or (ii) the registration statement
on Form SB-2 or such other form described in Section 10.1(iv) is not filed on or
before the Filing Date or not declared effective on or before the sooner of the
Effective Date, or within five days of receipt by the Company of a communication
from the Commission that the registration statement described in Section
10.1(iv) will not be reviewed, or (iii) any registration statement described in
Sections 10.1(i), 10.1(ii) or 10.1(iv) is filed and declared effective but shall
thereafter cease to be effective (without being succeeded immediately by an
additional registration statement filed and declared effective) for a period of
time which shall exceed 30 days in the aggregate per year but not more than 20
consecutive calendar days (defined as a period of 365 days commencing on the
date the Registration Statement is declared effective) (each such event referred
to in clauses (i), (ii) and (iii) of this Section 10.4 is referred to herein as
a "Non-Registration Event"), then, for so long as such Non-Registration Event
shall continue, the Company shall pay in cash as Liquidated Damages to each
holder of any Registrable Securities an amount equal to two (2%) percent per
month or part thereof after the first thirty days, of the pendency of such Non-
Registration Event, of the stated value of the Preferred Stock, whether or not
converted, and of the aggregate amount of the exercise prices of the Warrants
and Placement Warrants, whether or not exercised, then owned of record by such
holder as of the occurrence of such Non-Registration Event.  Payments to be made
pursuant to this Section 10.4 shall be due and payable immediately upon demand
in immediately available funds.  In the event a Mandatory Redemption payment is
demanded from the Company by the Holder of Preferred Stock, pursuant to Section
9.2 of this Subscription Agreement, then the Liquidated Damages described in
this Section 10.4 shall no longer accrue on the portion of the Purchase Price
underlying the Mandatory Redemption Payment, from and after the date the Holder
receives the Mandatory Redemption Payment.  It shall be deemed a Non-
Registration Event to the extent that any Shares into which Preferred Stock and
Put Stock (if issued) are convertible, assuming complete conversion of all
Preferred Stock, and Put Stock (if issued) and dividends thereon, are not
included in an effective registration statement as of and after the Effective
Date at the Conversion Price in effect from and after the Effective Date.

          10.5.  Expenses.  All expenses incurred by the Company in complying
                 --------
with Section 10, including, without limitation, all registration and filing
fees, printing expenses, fees and disbursements of counsel and independent
public accountants for the Company, fees and expenses

                                       15
<PAGE>

(including reasonable counsel fees) incurred in connection with complying with
state securities or "blue sky" laws, fees of the National Association of
Securities Dealers, Inc., transfer taxes, fees of transfer agents and
registrars, and costs of insurance are called "Registration Expenses". All
underwriting discounts and selling commissions applicable to the sale of
Registrable Securities, including any fees and disbursements of any special
counsel to the Seller, are called "Selling Expenses". The Seller shall pay the
fees of its own additional counsel, if any.

                 The Company will pay all Registration Expenses in connection
with the registration statement under Section 10. All Selling Expenses in
connection with each registration statement under Section 10 shall be borne by
the Seller and may be apportioned among the Sellers in proportion to the number
of shares sold by the Seller relative to the number of shares sold under such
registration statement or as all Sellers thereunder may agree.

          10.6.  Indemnification and Contribution.
                 --------------------------------

                    (a) In the event of a registration of any Registrable
Securities under the Act pursuant to Section 10, the Company will indemnify and
hold harmless the Seller, each officer of the Seller, each director of the
Seller, each underwriter of such Registrable Securities thereunder and each
other person, if any, who controls such Seller or underwriter within the meaning
of the 1933 Act, against any losses, claims, damages or liabilities, joint or
several, to which the Seller, or such underwriter or controlling person may
become subject under the Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon any untrue statement or alleged untrue statement of any material fact
contained in any registration statement under which such Registrable Securities
was registered under the Act pursuant to Section 10, any preliminary prospectus
or final prospectus contained therein, or any amendment or supplement thereof,
or arise out of or are based upon the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, and will reimburse the Seller, each such
underwriter and each such controlling person for any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability or action; provided, however, that the
Company will not be liable in any such case if and to the extent that any such
loss, claim, damage or liability arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission so made in
conformity with information furnished by any such Seller, the underwriter or any
such controlling person in writing specifically for use in such registration
statement or prospectus.

                    (b) In the event of a registration of any of the Registrable
Securities under the Act pursuant to Section 10, the Seller will indemnify and
hold harmless the Company, and each person, if any, who controls the Company
within the meaning of the Act, each officer of the Company who signs the
registration statement, each director of the Company, each underwriter and each
person who controls any underwriter within the meaning of the Act, against all
losses, claims, damages or liabilities, joint or several, to which the Company
or such officer, director, underwriter or controlling person may become subject
under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
the registration statement

                                       16
<PAGE>

under which such Registrable Securities were registered under the Act pursuant
to Section 10, any preliminary prospectus or final prospectus contained therein,
or any amendment or supplement thereof, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, or
the Seller's failure to comply with prospectus delivery requirements, and will
reimburse the Company and each such officer, director, underwriter and
controlling person for any legal or other expenses reasonably incurred by them
in connection with investigating or defending any such loss, claim, damage,
liability or action, provided, however, that the Seller will be liable hereunder
in any such case if and only to the extent that any such loss, claim, damage or
liability arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission made in reliance upon and in
conformity with information pertaining to such Seller, as such, furnished in
writing to the Company by such Seller specifically for use in such registration
statement or prospectus, and provided, further, however, that the liability of
the Seller hereunder shall be limited to the proportion of any such loss, claim,
damage, liability or expense which is equal to the proportion that the public
offering price of the Registrable Securities sold by the Seller under such
registration statement bears to the total public offering price of all
securities sold thereunder, but not in any event to exceed the gross proceeds
received by the Seller from the sale of Registrable Securities covered by such
registration statement.

               (c) Promptly after receipt by an indemnified party hereunder of
notice of the commencement of any action, such indemnified party shall, if a
claim in respect thereof is to be made against the indemnifying party hereunder,
notify the indemnifying party in writing thereof, but the omission so to notify
the indemnifying party shall not relieve it from any liability which it may have
to such indemnified party other than under this Section 10.6(c) and shall only
relieve it from any liability which it may have to such indemnified party under
this Section 10.6(c) if and to the extent the indemnifying party is prejudiced
by such omission. In case any such action shall be brought against any
indemnified party and it shall notify the indemnifying party of the commencement
thereof, the indemnifying party shall be entitled to participate in and, to the
extent it shall wish, to assume and undertake the defense thereof with counsel
satisfactory to such indemnified party, and, after notice from the indemnifying
party to such indemnified party of its election so to assume and undertake the
defense thereof, the indemnifying party shall not be liable to such indemnified
party under this Section 10.6(c) for any legal expenses subsequently incurred by
such indemnified party in connection with the defense thereof other than
reasonable costs of investigation and of liaison with counsel so selected,
provided, however, that, if the defendants in any such action include both the
indemnified party and the indemnifying party and the indemnified party shall
have reasonably concluded that there may be reasonable defenses available to it
which are different from or additional to those available to the indemnifying
party or if the interests of the indemnified party reasonably may be deemed to
conflict with the interests of the indemnifying party, the indemnified parties
shall have the right to select one separate counsel and to assume such legal
defenses and otherwise to participate in the defense of such action, with the
reasonable expenses and fees of such separate counsel and other expenses related
to such participation to be reimbursed by the indemnifying party as incurred.
The indemnifying party shall not be liable for amounts paid in settlement by the
indemnified party unless the indemnifying party has consented to the settlement,
which consent shall not be unreasonably withheld.

                                       17
<PAGE>

                    (d) In order to provide for just and equitable contribution
in the event of joint liability under the Act in any case in which either (i)
the Seller, or any controlling person of the Seller, makes a claim for
indemnification pursuant to this Section 10.6 but it is judicially determined
(by the entry of a final judgment or decree by a court of competent jurisdiction
and the expiration of time to appeal or the denial of the last right of appeal)
that such indemnification may not be enforced in such case notwithstanding the
fact that this Section 10.6 provides for indemnification in such case, or (ii)
contribution under the Act may be required on the part of the Seller or
controlling person of the Seller in circumstances for which indemnification is
provided under this Section 10.6; then, and in each such case, the Company and
the Seller will contribute to the aggregate losses, claims, damages or
liabilities to which they may be subject (after contribution from others) in
such proportion so that the Seller is responsible only for the portion
represented by the percentage that the public offering price of its securities
offered by the registration statement bears to the public offering price of all
securities offered by such registration statement, provided, however, that, in
any such case, (A) the Seller will not be required to contribute any amount in
excess of the public offering price of all such securities offered by it
pursuant to such registration statement; and (B) no person or entity guilty of
fraudulent misrepresentation (within the meaning of Section 10(f) of the Act)
will be entitled to contribution from any person or entity who was not guilty of
such fraudulent misrepresentation.

          11.1. Obligation To Purchase.
                ----------------------

                    (a) The Subscriber agrees to purchase from the Company

Placement Warrants are referred to as the "Put Securities".) The Holders of the
Put Securities are granted all the rights, undertakings, remedies, liquidated

procedures set forth in Sections 9.1, 9.2, 9.3, 9.4, 9.5, and the registration
rights described in Section 10 hereof.

                    (b) The agreement to purchase the Put Securities is

as any effect on the business, operations, properties, prospects, or financial
condition of the Company that is material and adverse to the Company and its
subsidiaries and affiliates, taken as a whole, and/or any condition,
circumstance, or situation that would prohibit or otherwise interfere with the
ability of the Company to enter into and perform any of its obligations under
this Agreement, or any other agreement entered into or to be entered into in
connection herewith, in any material respect.

               (vi)   The execution and delivery to the Subscriber of a
certificate signed by the Company's chief executive officer representing the
truth and accuracy of all the Company's representations and warranties contained
in this Subscription Agreement as of the Put Date, and Put Closing Date and

satisfaction of all contingencies and conditions required for the exercise of
the Put.

               (vii)  The Company's continued listing on and compliance at all
times after the date hereof with the listing requirements of the NASDAQ National

               (viii) The Company's not having received notice from the NASDAQ
National Market (or any principal market on which the Company's common stock is
listed for trading) that the Company is not in compliance with the requirements
for continued listing.

               (ix)   The execution by the Company and delivery to the
Subscriber of all documents reasonably necessary to memorialize the rights and
obligations of each of the parties in relation to the Put.

Federal Aviation Administration certifying such tests results.

               (xi)   The average closing bid price of the Common Stock as
reported by NASDAQ National Market for the three trading days preceding a Put
Date is not less than 150% of the average closing bid price of the Common Stock
as reported by the NASDAQ National Market

                                       19
<PAGE>

for the three trading days preceding the Closing Date, provided that this
condition shall apply only to the portion of the Put Purchase Price payable up
to 90 days after the Actual Effective Date.


          11.2.  Exercise of Put.
                 ---------------

                 (a) The Company's right to exercise the Put commences on the
actual effective date of the registration statement described Section 10.1(iv)
hereof in relation to all the Securities and Put Securities ("Actual Effective
Date") and expires fifteen (15) business days thereafter ("Put Exercise
Period").

                 (b) The Put may be exercised by the Company by the giving to
the Subscriber of a written notice of exercise ("Put Notice") during the Put
Exercise Period in relation to the subject Put Securities. The date a Put Notice
is given is a Put Date. Each Put Notice must be accompanied by the (i) officer's
certificate described in Section 11.1(b)(vi) above; (ii) the original legal
opinion described in Section 7.1(e); (iii) a legal opinion relating to the Put
Securities in form reasonably acceptable to Subscriber; and (iv) proof of
effectiveness of the registration statement in which the Securities and Put
Securities are registered together with five copies of the prospectus relating
to the Securities and Put Securities.

                 (c) Unless otherwise agreed to by the Subscribers, Put Notices
must be given to all Subscribers in proportion to the amounts agreed to be
purchased by all Subscribers undertaking to purchase Put Shares in the initial
$5,000,000 installment of the aggregate $10,000,000 offering to which this and
other Subscription Agreements relate. The aggregate amount of all Put Notices
may not exceed $5,000,000. In the event the Company does not exercise the Put
during the Put Exercise Period for the entire Put amount, then the Subscriber
may exercise the Put on behalf of the Company in relation only to such
Subscriber, by giving notice to the Company of such exercise during the seven
(7) business days following the Put Exercise Period.

                 (d) After receipt by Subscriber of a Put Notice and the items
set forth in Section 11.2(b) above the Subscriber must pay an amount equal to
40% of the Purchase Price set forth on the signature page hereto within thirty
days after the Actual Effective Date, and an amount equal to 60% of the Purchase

hereto.

                 (e) Maximum Put Exercise. The Company may not give the
                     --------------------
Subscriber a Put Notice in connection with that amount of Put Securities which
could be converted as of the Put Date into a number of shares of Common Stock
which would be in excess of the sum of (i) the number of shares of Common Stock
beneficially owned by the Subscriber and its affiliates on such Put Date, and
(ii) the number of shares of Common Stock issuable upon the conversion of the
Put Stock and exercise of the Put Warrants with respect to which the

being made on a Put Date, which would result in beneficial ownership by the
Subscriber and its affiliates of more than 9.99% of the outstanding shares of
Common Stock of the Company on such Put Date. For the purposes of the proviso to
the immediately preceding sentence, beneficial ownership shall be determined in
accordance with Section 13(d) of the Securities Exchange Act of 1934, as
amended, and Regulation 13d-3 thereunder.

          11.3.  Put Commission.  The Placement Agents identified on Schedule B
                 --------------
hereto shall receive aggregate finder's fees in connection with the closing of
the Put of cash equal to nine (9%) percent of the Put Purchase Price and Put
Commission Warrants as set forth on Schedule B hereto. Collectively, the
foregoing are referred to as Put Commissions.  Put Commissions shall be payable
only in connection with the Put Purchase Price actually paid by a Subscriber.

          12.    Reset.  In the event the average closing bid price of the
                 -----
Company Shares as reported by the NASDAQ National Market or such other principal
exchange where the Company Shares are listed for trading ("Closing Bid Price")
for the three trading days preceding the first anniversary of the Closing Date
("Initial Price") is less than 200% of the Closing Bid Price for the three
trading days prior to the issue date of Preferred Stock who receive Preferred
Stock in the Company's initial offering of Preferred Stock, then the Company
will issue to the Subscriber within ten business days after the first
anniversary of the Closing Date the number of Company Shares determined by
subtracting (the Purchase Price divided by the Initial Price) from (the Purchase
Price divided by 90% of the Initial Price) ("Additional Shares"). The Subscriber
is granted the demand and piggy-back registration rights described in Section
10.1(i) and 10.1(ii) hereof in relation to the Additional Shares. The holding
period of the Additional Shares for purposes of Rule 144 of the Securities Act
of 1933 shall be deemed to have begun on the Closing Date. Failure to timely
deliver the Additional Shares shall be deemed an Event of Default pursuant to
Section 8 of the Certificate of Designation.

          13.    Offering Restrictions.  Until 120 days after the Actual
                 ---------------------
Effective Date, the Company agrees not to issue any equity, convertible debt or
other securities at a per common share equivalent price less than the Closing
Ask price of the Company's common stock in effect as of the date of such
issuance as reported by NASDAQ National Market or such other principal market or
exchange where the Company's common stock is listed for trading. The restriction
described in this Section 13 shall not apply if the Subscriber fails to timely
pay to the Company funds payable in connection with a Put exercise.

               (c) Except as provided in clause (d) below, if the Company's
Common Stock is not publicly traded, then as the Holder and the Company agree or
in the absence of agreement by arbitration in accordance with the rules then
standing of the American Arbitration Association, before a single arbitrator to
be chosen from a panel of persons qualified by education and training to pass on
the matter to be decided.

               (d) If the Determination Date is the date of a liquidation,
dissolution or winding up, or any event deemed to be a liquidation, dissolution
or winding up pursuant to the Company's charter, then all amounts to be payable
per share to holders of the Common Stock pursuant to the charter in the event of
such liquidation, dissolution or winding up, plus all other amounts to be
payable per share in respect of the Common Stock in liquidation under the
charter, assuming for the purposes of this clause (d) that all of the shares of
Common Stock then issuable upon exercise of all of the Warrants are outstanding
at the Determination Date.

          1.5. Company Acknowledgment. The Company will, at the time of the
               ----------------------
exercise of the Warrant, upon the request of the holder hereof acknowledge in
writing its continuing obligation to afford to such holder any rights to which
such holder shall continue to be entitled after such exercise in accordance with
the provisions of this Warrant. If the holder shall fail to make any such
request, such failure shall not affect the continuing obligation of the Company
to afford to such holder any such rights.

          1.6. Trustee for Warrant Holders. In the event that a bank or trust
               ---------------------------
company shall have been appointed as trustee for the holders of the Warrants
pursuant to Subsection 3.2, such bank or trust company shall have all the powers
and duties of a warrant agent appointed pursuant to Section 12 and shall accept,
in its own name for the account of the Company or such successor person as may
be entitled thereto, all amounts otherwise payable to the Company or such
successor,

                                       3
<PAGE>

as the case may be, on exercise of this Warrant pursuant to this Section 1.

          1.7. Exercise by Telecopier.  The exercise date of this Warrant will
               ----------------------
be deemed to be the date the form of subscription attached as Exhibit A is
delivered by telecopier to the Company at its principal office or at the office
of its Warrant Agent (as provided in Section 12) provided that the original form
of subscription and payment are delivered within five business days of
telecopier delivery of the form of subscription.

     2.1. Delivery of Stock Certificates, etc. on Exercise. The Company agrees
          ------------------------------------------------
that the shares of Common Stock purchased upon exercise of this Warrant shall be
deemed to be issued to the holder hereof as the record owner of such shares as
of the close of business on the date on which this Warrant shall have been
surrendered and payment made for such shares as aforesaid. As soon as
practicable after the exercise of this Warrant in full or in part, and in any
event within three business days thereafter, the Company at its expense
(including the payment by it of any applicable issue taxes) will cause to be
issued in the name of and delivered to the holder hereof, or as such holder
(upon payment by such holder of any applicable transfer taxes) may direct in
compliance with applicable Securities Laws, a certificate or certificates for
the number of duly and validly issued, fully paid and nonassessable shares of
Common Stock (or Other Securities) to which such holder shall be entitled on
such exercise, plus, in lieu of any fractional share to which such holder would
otherwise be entitled, cash equal to such fraction multiplied by the then Fair
Market Value of one full share, together with any other stock or other
securities and property (including cash, where applicable) to which such holder
is entitled upon such exercise pursuant to Section 1 or otherwise.

     2.2. Cashless Exercise.
          ------------------

          (a) Payment may be made either in (a) cash or by certified or official
bank check or checks payable to the order of the Company equal to the applicable
aggregate Purchase Price, (ii) by delivery of Warrants, Common Stock and/or
Common Stock receivable upon exercise of the Warrants in accordance with Section
(b) below, or (iii) by a combination of any of the foregoing methods) for the
number of Common Shares specified in such form (as such exercise number shall be
adjusted to reflect any adjustment in the total number of shares of Common Stock
issuable to the holder per the terms of this Warrant) and the holder shall
thereupon be entitled to receive the number of duly authorized, validly issued,
fully-paid and non-assessable shares of Common Stock (or Other Securities)
determined as provided herein.

          (b) Notwithstanding any provisions herein to the contrary, if the Fair
Market Value of one share of Common Stock is greater than the Purchase Price (at
the date of calculation as set forth below), in lieu of exercising this Warrant
for cash the holder may elect to receive shares equal to the value (as
determined below) of this Warrant (or the portion thereof being cancelled) by
surrender of this Warrant at the principal office of the Company together with
the properly endorsed Subscription Form in which event the Company shall issue
to the holder a number of shares of Common Stock computed using the following
formula:

                                       4
<PAGE>

               X=Y (A-B)
                    ---
                     A
               -------

        Where  X=  the number of shares of Common Stock to be issued to the
                   holder

               Y=  the number of shares of Common Stock purchasable under the
                   Warrant or, if only a portion of the Warrant is being
                   exercised, the portion of the Warrant being exercised (at the
                   date of such calculation)

               A=  the Fair Market Value of one share of the Company's Common
                   Stock (at the date of such calculation)

               B=  Purchase Price (as adjusted to the date of such calculation)

     3. Adjustment for Reorganization, Consolidation, Merger, etc.
        ---------------------------------------------------------

        3.1.  Reorganization, Consolidation, Merger, etc. In case at any time
              ------------------------------------------
or from time to time, the Company shall (a) effect a reorganization, (b)
consolidate with or merge into any other person, or (c) transfer all or
substantially all of its properties or assets to any other person under any plan
or arrangement contemplating the dissolution of the Company, then, in each such
case, as a condition to the consummation of such a transaction, proper and
adequate provision shall be made by the Company whereby the holder of this
Warrant, on the exercise hereof as provided in Section 1 at any time after the
consummation of such reorganization, consolidation or merger or the effective
date of such dissolution, as the case may be, shall receive, in lieu of the
Common Stock (or Other Securities) issuable on such exercise prior to such
consummation or such effective date, the stock and other securities and property
(including cash) to which such holder would have been entitled upon such
consummation or in connection with such dissolution, as the case may be, if such
holder had so exercised this Warrant, immediately prior thereto, all subject to
further adjustment thereafter as provided in Section 4.

        3.2.  Dissolution. In the event of any dissolution of the Company
              -----------
following the transfer of all or substantially all of its properties or assets,
the Company, prior to such dissolution, shall at its expense deliver or cause to
be delivered the stock and other securities and property (including cash, where
applicable) receivable by the holders of the Warrants after the effective date
of such dissolution pursuant to this Section 3 to a bank or trust company having
its principal office in New York, NY, as trustee for the holder or holders of
the Warrants.

        3.3.  Continuation of Terms. Upon any reorganization, consolidation,
              ---------------------
merger or transfer (and any dissolution following any transfer) referred to in
this Section 3.3, this Warrant shall continue in full force and effect and the
terms hereof shall be applicable to the shares of stock and other securities and
property receivable on the exercise of this Warrant after the consummation of
such reorganization, consolidation or merger or the effective date of
dissolution following any such

                                       5
<PAGE>

transfer, as the case may be, and shall be binding upon the issuer of any such
stock or other securities, including, in the case of any such transfer, the
person acquiring all or substantially all of the properties or assets of the
Company, whether or not such person shall have expressly assumed the terms of
this Warrant as provided in Section 4. In the event this Warrant does not
continue in full force and effect after the consummation of the transaction
described in this Section 3.3, then only in such event will the Company's
securities and property (including cash, where applicable) receivable by the
holders of the Warrants be delivered to the Trustee as contemplated by Section
3.2.

     4.  Extraordinary Events Regarding Common Stock. In the event that the
         -------------------------------------------
Company shall (a) issue additional shares of the Common Stock as a dividend or
other distribution on outstanding Common Stock, (b) subdivide its outstanding
shares of Common Stock, or (c) combine its outstanding shares of the Common
Stock into a smaller number of shares of the Common Stock, then, in each such
event, the Purchase Price shall, simultaneously with the happening of such
event, be adjusted by multiplying the then Purchase Price by a fraction, the
numerator of which shall be the number of shares of Common Stock outstanding
immediately prior to such event and the denominator of which shall be the number
of shares of Common Stock outstanding immediately after such event, and the
product so obtained shall thereafter be the Purchase Price then in effect. The
Purchase Price, as so adjusted, shall be readjusted in the same manner upon the
happening of any successive event or events described herein in this Section 4.
The number of shares of Common Stock that the holder of this Warrant shall
thereafter, on the exercise hereof as provided in Section 1, be entitled to
receive shall be increased to a number determined by multiplying the number of
shares of Common Stock that would otherwise (but for the provisions of this
Section 4) be issuable on such exercise by a fraction of which (a) the numerator
is the Purchase Price that would otherwise (but for the provisions of this
Section 4) be in effect, and (b) the denominator is the Purchase Price in effect
on the date of such exercise.

     5.  Certificate as to Adjustments. In each case of any adjustment or
         -----------------------------
readjustment in the shares of Common Stock (or Other Securities) issuable on the
exercise of the Warrants, the Company at its expense will promptly cause its
Chief Financial Officer or other appropriate designee to compute such adjustment
or readjustment in accordance with the terms of the Warrant and prepare a
certificate setting forth such adjustment or readjustment and showing in detail
the facts upon which such adjustment or readjustment is based, including a
statement of (a) the consideration received or receivable by the Company for any
additional shares of Common Stock (or Other Securities) issued or sold or deemed
to have been issued or sold, (b) the number of shares of Common Stock (or Other
Securities) outstanding or deemed to be outstanding, and (c) the Purchase Price
and the number of shares of Common Stock to be received upon exercise of this
Warrant, in effect immediately prior to such adjustment or readjustment and as
adjusted or readjusted as provided in this Warrant. The Company will forthwith
mail a copy of each such certificate to the holder of the Warrant and any
Warrant agent of the Company (appointed pursuant to Section 10 hereof).

     6.  Reservation of Stock, etc. Issuable on Exercise of Warrant; Financial
         ---------------------------------------------------------------------
Statements. The Company will at all times reserve and keep available, solely for
- ----------
issuance and delivery on the exercise of the Warrants, all shares of Common
Stock (or Other Securities) from time to time issuable on the

                                       6
<PAGE>

exercise of the Warrant. This Warrant entitles the holder hereof to receive
copies of all financial and other information distributed or required to be
distributed to the holders of the Company's Common Stock.

     7.  Assignment; Exchange of Warrant. Subject to compliance with applicable
         -------------------------------
Securities laws, this Warrant, and the rights evidenced hereby, may be
transferred by any registered holder hereof (a "Transferor") with respect to any
or all of the Shares. On the surrender for exchange of this Warrant, with the
Transferor's endorsement in the form of Exhibit B attached hereto (the
Transferor Endorsement Form") and together with evidence reasonably satisfactory
to the Company demonstrating compliance with applicable Securities Laws, the
Company at its expense but with payment by the Transferor of any applicable
transfer taxes) will issue and deliver to or on the order of the Transferor
thereof a new Warrant or Warrants of like tenor, in the name of the Transferor
and/or the transferee(s) specified in such Transferor Endorsement Form (each a
"Transferee"), calling in the aggregate on the face or faces thereof for the
number of shares of Common Stock called for on the face or faces of the Warrant
so surrendered by the Transferor.

     8.  Replacement of Warrant. On receipt of evidence reasonably satisfactory
         ----------------------
to the Company of the loss, theft, destruction or mutilation of this Warrant
and, in the case of any such loss, theft or destruction of this Warrant, on
delivery of an indemnity agreement or security reasonably satisfactory in form
and amount to the Company or, in the case of any such mutilation, on surrender
and cancellation of this Warrant, the Company at its expense will execute and
deliver, in lieu thereof, a new Warrant of like tenor.

     9.  Registration Rights/ Shareholder Approval.  The holder of this Warrant
         -----------------------------------------
has been granted certain registration rights by the Company.  These registration
rights are set forth in a Subscription Agreement entered into by the Company and
Subscribers of the Company's Series A 5% Preferred Stock at or prior to the
issue date of this Warrant.  The terms of the Subscription Agreement are
incorporated herein by this reference.  The holder of this Warrant may not
exercise his rights hereunder to purchase some or all of the Common Stock
issuable upon exercise of this Warrant until the Company obtains the Approval,
as defined in the Subscription Agreement.  Upon (i) after the occurrence and
during the pendency of a Non-Registration Event as described in the Subscription
Agreement, from and after the Effective Date (as defined in the Subscription
Agreement); or (ii) after the occurrence and during the pendency of an Approval
Default, then, within five days after written demand to the Company from the
Holder, the Company will pay to the Holder of this Warrant, in lieu of
delivering Common Stock, a sum equal to the closing ask price of the Company's
Common Stock on the NASDAQ National Market or such other principal trading
market for the Company's Common Stock on the trading date immediately preceding
the date notice is given by the Holder, less the Purchase Price of this Warrant,
for each share of Common Stock designated in such notice from the Holder.

     10. Call Option.  The Company shall have the option to "call" the Warrants
         -----------
(the "Warrant Call"), in accordance with and governed by the following:

                                       7
<PAGE>

          (a) The Company shall exercise the Warrant Call by giving to each
Warrant Holder a written notice of call (the "Call Notice") during the period in
which the Warrant Call may be exercised.

          (b) The Company's right to exercise the Warrant Call shall commence
with the Actual Effective Date, as defined in Section 11.2(a) of the
Subscription Agreement and thereafter, shall be coterminous with the exercise
period of the Warrants for a maximum of 50% of the Common Stock issuable upon
the exercise of this Warrant (the "Warrant Shares"), provided, that the
registration statement is effective at the date the Call Notice is given and
through the period ending 14 business days thereafter.  In no event may the
Company exercise the Warrant Call at any time unless the Warrant Shares to be
delivered upon exercise of the Warrant, will be upon delivery, immediately
resalable, without restrictive legend and upon such resale freely transferable
on the transfer books of the Company.

          (c) Unless otherwise agreed to by the Warrant Holder, the Call Notices
must be given to all Warrant Holders who receive Warrants similar to this
Warrant on or about the same issue date as this Warrant in proportion to the
amounts of Common Stock which can be purchased by the respective Warrant Holders
in accordance with the respective Warrant held by each.

          (d) The Company may give a Call Notice in connection with up to 25% of
the Common Stock issuable upon exercise of this Warrant provided the closing bid
price of the Common Stock as reported by the NASDAQ National Market for each of
the thirty days prior to the giving of the Call Notice ("Lookback Period") is
200% of the Purchase Price and the average daily trading volume of the Common
Stock during the Lookback Period is not less than 150,000 Common Shares.  A Call
Notice may be given for an additional 25% of the Common Stock issuable upon
exercise of this Warrant provided the average daily trading volume during the
Lookback Period is at least 250,000 Common Shares.

          (e) The respective Warrant Holders shall exercise their Warrant rights
and purchase the appropriate Warrant Shares and pay for same within 14 business
days of the date of the Call Notice.  If the Warrant Holder fails to timely pay
the funds required by the Warrant Call, the Company may elect to cancel a
corresponding amount of this Warrant.

          (f) The Company may not exercise the right to Call this Warrant or any
part of it after the occurrence of a Non-Registration Event or Approval Default,
as defined in the Subscription Agreement, unless same were subject to cure and
cured during the stated cure period.

     11.  Maximum Exercise.  The Holder shall not be entitled to exercise, on an
          ----------------
exercise date, this Warrant in connection with that number of shares of Common
Stock which would be in excess of the sum of (i) the number of shares of Common
Stock beneficially owned by the Holder and its affiliates on an exercise date,
and (ii) the number of shares of Common Stock issuable upon the exercise of this
Warrant with respect to which the determination of this proviso is being made on
an exercise date, which would result in beneficial ownership by the Holder and
its affiliates of more

                                       8
<PAGE>

than 9.99% of the outstanding shares of Common Stock of the Company on such
exercise date. For the purposes of the proviso to the immediately preceding
sentence, beneficial ownership shall be determined in accordance with Section
13(d) of the Securities Exchange Act of 1934, as amended, and Regulation 13d-3
thereunder. Subject to the foregoing, the Holder shall not be limited to
aggregate exercises which would result in the issuance of more than 9.99%. The
restriction described in this paragraph may be revoked upon 75 days prior notice
from the Holder to the Company. The Holder may allocate which of the equity of
the Company deemed beneficially owned by the Holder shall be included in the
9.9% amount described above and which shall be allocated to the excess above
9.99%.

     12.  Warrant Agent.  The Company may, by written notice to the each holder
          -------------
of the Warrant, appoint an agent for the purpose of issuing Common Stock (or
Other Securities) on the exercise of this Warrant pursuant to Section 1,
exchanging this Warrant pursuant to Section 7, and replacing this Warrant
pursuant to Section 8, or any of the foregoing, and thereafter any such
issuance, exchange or replacement, as the case may be, shall be made at such
office by such agent.

     13.  Transfer on the Company's Books.  Until this Warrant is transferred on
          -------------------------------
the books of the Company, the Company may treat the registered holder hereof as
the absolute owner hereof for all purposes, notwithstanding any notice to the
contrary.

     14.  Notices, etc.  All notices and other communications from the Company
          ------------
to the holder of this Warrant shall be mailed by first class registered or
certified mail, postage prepaid, at such address as may have been furnished to
the Company in writing by such holder or, until any such holder furnishes to the
Company an address, then to, and at the address of, the last holder of this
Warrant who has so furnished an address to the Company.

     15.  Miscellaneous. This Warrant and any term hereof may be changed,
          -------------
waived, discharged or terminated only by an instrument in writing signed by the
party against which enforcement of such change, waiver, discharge or termination
is sought. This Warrant shall be construed and enforced in accordance with and
governed by the laws of New York.  Any dispute relating to this Warrant shall be
adjudicated in New York State.  The headings in this Warrant are for purposes of
reference only, and shall not limit or otherwise affect any of the terms hereof.

writing its continuing obligation to afford to such holder any rights to which
such holder shall continue to be entitled after such exercise in accordance with
the provisions of this Warrant. If the holder shall fail to make any such
request, such failure shall not affect the continuing obligation of the Company
to afford to such holder any such rights.

          1.6. Trustee for Warrant Holders. In the event that a bank or trust
               ---------------------------
company shall have been appointed as trustee for the holders of the Warrants
pursuant to Subsection 3.2, such bank or trust company shall have all the powers
and duties of a warrant agent appointed pursuant to Section 12 and shall accept,
in its own name for the account of the Company or such successor person as may

           1.7. Exercise by Telecopier.  The exercise date of this Warrant will
                ----------------------

of subscription and payment are delivered within five business days of
telecopier delivery of the form of subscription.

     2.1.  Delivery of Stock Certificates, etc. on Exercise. The Company agrees
           ------------------------------------------------
that the shares of Common Stock purchased upon exercise of this Warrant shall be
deemed to be issued to the holder hereof as the record owner of such shares as
of the close of business on the date on which this Warrant shall have been
surrendered and payment made for such shares as aforesaid. As soon as
practicable after the exercise of this Warrant in full or in part, and in any
event within three business days thereafter, the Company at its expense
(including the payment by it of any applicable issue taxes) will cause to be
issued in the name of and delivered to the holder hereof, or as such holder
(upon payment by such holder of any applicable transfer taxes) may direct in
compliance with applicable Securities Laws, a certificate or certificates for
the number of duly and validly issued, fully paid and nonassessable shares of
Common Stock (or Other Securities) to which such holder shall be entitled on
such exercise, plus, in lieu of any fractional share to which such holder would
otherwise be entitled, cash equal to such fraction multiplied by the then Fair
Market Value of one full share, together with any other stock or other
securities and property (including cash, where applicable) to which such holder
is entitled upon such exercise pursuant to Section 1 or otherwise.

     2.2.  Cashless Exercise.
           ------------------

           (a) Payment may be made either in (a) cash or by certified or
official bank check or checks payable to the order of the Company equal to the
applicable aggregate Purchase Price, (ii) by delivery of Warrants, Common Stock
and/or Common Stock receivable upon exercise of the Warrants in accordance with
Section (b) below, or (iii) by a combination of any of the foregoing methods)
for the number of Common Shares specified in such form (as such exercise number
shall be adjusted to reflect any adjustment in the total number of shares of
Common Stock issuable to the holder per the terms of this Warrant) and the
holder shall thereupon be entitled to receive the number of duly authorized,
validly issued, fully-paid and non-assessable shares of Common Stock (or Other
Securities) determined as provided herein.

           (b) Notwithstanding any provisions herein to the contrary, if the
Fair Market Value of one share of Common Stock is greater than the Purchase
Price (at the date of calculation as set forth below), in lieu of exercising
this Warrant for cash the holder may elect to receive shares equal to the value
(as determined below) of this Warrant (or the portion thereof being cancelled)
by surrender of this Warrant at the principal office of the Company together
with the properly endorsed Subscription Form in which event the Company shall
issue to the holder a number of shares of Common Stock computed using the
following formula:

                                       4
<PAGE>

               X=Y (A-B)
                    ---
                     A
               -------

         Where X=  the number of shares of Common Stock to be issued to the
                   holder

               Y=  the number of shares of Common Stock purchasable under the
                   Warrant or, if only a portion of the Warrant is being
                   exercised, the portion of the Warrant being exercised (at the
                   date of such calculation)

               A=  the Fair Market Value of one share of the Company's Common
                   Stock (at the date of such calculation)

               B=  Purchase Price (as adjusted to the date of such calculation)

     3.  Adjustment for Reorganization, Consolidation, Merger, etc.
         ---------------------------------------------------------

         3.1.  Reorganization, Consolidation, Merger, etc. In case at any time
               ------------------------------------------
or from time to time, the Company shall (a) effect a reorganization, (b)
consolidate with or merge into any other person, or (c) transfer all or
substantially all of its properties or assets to any other person under any plan
or arrangement contemplating the dissolution of the Company, then, in each such
case, as a condition to the consummation of such a transaction, proper and
adequate provision shall be made by the Company whereby the holder of this
Warrant, on the exercise hereof as provided in Section 1 at any time after the
consummation of such reorganization, consolidation or merger or the effective
date of such dissolution, as the case may be, shall receive, in lieu of the
Common Stock (or Other Securities) issuable on such exercise prior to such
consummation or such effective date, the stock and other securities and property
(including cash) to which such holder would have been entitled upon such
consummation or in connection with such dissolution, as the case may be, if such
holder had so exercised this Warrant, immediately prior thereto, all subject to
further adjustment thereafter as provided in Section 4.

         3.2.  Dissolution. In the event of any dissolution of the Company
               -----------
following the transfer of all or substantially all of its properties or assets,
the Company, prior to such dissolution, shall at its expense deliver or cause to
be delivered the stock and other securities and property (including cash, where
applicable) receivable by the holders of the Warrants after the effective date
of such dissolution pursuant to this Section 3 to a bank or trust company having
its principal office in New York, NY, as trustee for the holder or holders of
the Warrants.

         3.3.  Continuation of Terms. Upon any reorganization, consolidation,
               ---------------------
merger or transfer (and any dissolution following any transfer) referred to in
this Section 3.3, this Warrant shall continue in full force and effect and the
terms hereof shall be applicable to the shares of stock and other securities and
property receivable on the exercise of this Warrant after the consummation of
such reorganization, consolidation or merger or the effective date of
dissolution following any such

                                       5
<PAGE>

transfer, as the case may be, and shall be binding upon the issuer of any such
stock or other securities, including, in the case of any such transfer, the
person acquiring all or substantially all of the properties or assets of the
Company, whether or not such person shall have expressly assumed the terms of
this Warrant as provided in Section 4. In the event this Warrant does not
continue in full force and effect after the consummation of the transaction
described in this Section 3.3, then only in such event will the Company's
securities and property (including cash, where applicable) receivable by the
holders of the Warrants be delivered to the Trustee as contemplated by Section
3.2.

     4.   Extraordinary Events Regarding Common Stock. In the event that the
          -------------------------------------------
Company shall (a) issue additional shares of the Common Stock as a dividend or
other distribution on outstanding Common Stock, (b) subdivide its outstanding
shares of Common Stock, or (c) combine its outstanding shares of the Common
Stock into a smaller number of shares of the Common Stock, then, in each such
event, the Purchase Price shall, simultaneously with the happening of such
event, be adjusted by multiplying the then Purchase Price by a fraction, the
numerator of which shall be the number of shares of Common Stock outstanding
immediately prior to such event and the denominator of which shall be the number
of shares of Common Stock outstanding immediately after such event, and the
product so obtained shall thereafter be the Purchase Price then in effect. The
Purchase Price, as so adjusted, shall be readjusted in the same manner upon the
happening of any successive event or events described herein in this Section 4.
The number of shares of Common Stock that the holder of this Warrant shall
thereafter, on the exercise hereof as provided in Section 1, be entitled to
receive shall be increased to a number determined by multiplying the number of
shares of Common Stock that would otherwise (but for the provisions of this
Section 4) be issuable on such exercise by a fraction of which (a) the numerator
is the Purchase Price that would otherwise (but for the provisions of this
Section 4) be in effect, and (b) the denominator is the Purchase Price in effect
on the date of such exercise.

     5.   Certificate as to Adjustments. In each case of any adjustment or
          -----------------------------
readjustment in the shares of Common Stock (or Other Securities) issuable on the
exercise of the Warrants, the Company at its expense will promptly cause its
Chief Financial Officer or other appropriate designee to compute such adjustment
or readjustment in accordance with the terms of the Warrant and prepare a
certificate setting forth such adjustment or readjustment and showing in detail
the facts upon which such adjustment or readjustment is based, including a
statement of (a) the consideration received or receivable by the Company for any
additional shares of Common Stock (or Other Securities) issued or sold or deemed
to have been issued or sold, (b) the number of shares of Common Stock (or Other
Securities) outstanding or deemed to be outstanding, and (c) the Purchase Price
and the number of shares of Common Stock to be received upon exercise of this
Warrant, in effect immediately prior to such adjustment or readjustment and as
adjusted or readjusted as provided in this Warrant. The Company will forthwith
mail a copy of each such certificate to the holder of the Warrant and any
Warrant agent of the Company (appointed pursuant to Section 10 hereof).

     6.   Reservation of Stock, etc. Issuable on Exercise of Warrant; Financial
          ---------------------------------------------------------------------
Statements. The Company will at all times reserve and keep available, solely for
- ----------
issuance and delivery on the exercise of the Warrants, all shares of Common
Stock (or Other Securities) from time to time issuable on the

                                       6

copies of all financial and other information distributed or required to be
distributed to the holders of the Company's Common Stock.

     7.  Assignment; Exchange of Warrant. Subject to compliance with applicable
         -------------------------------
Securities laws, this Warrant, and the rights evidenced hereby, may be
transferred by any registered holder hereof (a "Transferor") with respect to any
or all of the Shares. On the surrender for exchange of this Warrant, with the
Transferor's endorsement in the form of Exhibit B attached hereto (the
Transferor Endorsement Form") and together with evidence reasonably satisfactory
to the Company demonstrating compliance with applicable Securities Laws, the
Company at its expense but with payment by the Transferor of any applicable
transfer taxes) will issue and deliver to or on the order of the Transferor
thereof a new Warrant or Warrants of like tenor, in the name of the Transferor
and/or the transferee(s) specified in such Transferor Endorsement Form (each a
"Transferee"), calling in the aggregate on the face or faces thereof for the
number of shares of Common Stock called for on the face or faces of the Warrant
so surrendered by the Transferor.

     8.  Replacement of Warrant. On receipt of evidence reasonably satisfactory
         ----------------------
to the Company of the loss, theft, destruction or mutilation of this Warrant
and, in the case of any such loss, theft or destruction of this Warrant, on
delivery of an indemnity agreement or security reasonably satisfactory in form
and amount to the Company or, in the case of any such mutilation, on surrender
and cancellation of this Warrant, the Company at its expense will execute and
deliver, in lieu thereof, a new Warrant of like tenor.

     9.  Registration Rights/ Shareholder Approval.  The holder of this Warrant
         -----------------------------------------
has been granted certain registration rights by the Company.  These registration
rights are set forth in a Subscription Agreement entered into by the Company and
Subscribers of the Company's Series A 5% Preferred Stock at or prior to the
issue date of this Warrant.  The terms of the Subscription Agreement are
incorporated herein by this reference.  The holder of this Warrant may not
exercise his rights hereunder to purchase some or all of the Common Stock
issuable upon exercise of this Warrant until the Company obtains the Approval,
as defined in the Subscription Agreement.  Upon (i) after the occurrence and
during the pendency of a Non-Registration Event as described in the Subscription
Agreement, from and after the Effective Date (as defined in the Subscription
Agreement); or (ii) after the occurrence and during the pendency of an Approval
Default, then, within five days after written demand to the Company from the
Holder, the Company will pay to the Holder of this Warrant, in lieu of
delivering Common Stock, a sum equal to the closing ask price of the Company's
Common Stock on the NASDAQ National Market or such other principal trading
market for the Company's Common Stock on the trading date immediately preceding
the date notice is given by the Holder, less the Purchase Price of this Warrant,
for each share of Common Stock designated in such notice from the Holder.

     10. Call Option.  The Company shall have the option to "call" the Warrants
         -----------
(the "Warrant Call"), in accordance with and governed by the following:

                                       7
<PAGE>

          (a) The Company shall exercise the Warrant Call by giving to each
Warrant Holder a written notice of call (the "Call Notice") during the period in
which the Warrant Call may be exercised.

          (b) The Company's right to exercise the Warrant Call shall commence
with the Actual Effective Date, as defined in Section 11.2(a) of the
Subscription Agreement and thereafter, shall be coterminous with the exercise
period of the Warrants for a maximum of 50% of the Common Stock issuable upon
the exercise of this Warrant (the "Warrant Shares"), provided, that the
registration statement is effective at the date the Call Notice is given and
through the period ending 14 business days thereafter.  In no event may the
Company exercise the Warrant Call at any time unless the Warrant Shares to be
delivered upon exercise of the Warrant, will be upon delivery, immediately
resalable, without restrictive legend and upon such resale freely transferable
on the transfer books of the Company.

          (c) Unless otherwise agreed to by the Warrant Holder, the Call Notices
must be given to all Warrant Holders who receive Warrants similar to this
Warrant on or about the same issue date as this Warrant in proportion to the
amounts of Common Stock which can be purchased by the respective Warrant Holders
in accordance with the respective Warrant held by each.

          (d) The Company may give a Call Notice in connection with up to 25% of
the Common Stock issuable upon exercise of this Warrant provided the closing bid
price of the Common Stock as reported by the NASDAQ National Market for each of
the thirty days prior to the giving of the Call Notice ("Lookback Period") is
200% of the Purchase Price and the average daily trading volume of the Common
Stock during the Lookback Period is not less than 150,000 Common Shares.  A Call
Notice may be given for an additional 25% of the Common Stock issuable upon
exercise of this Warrant provided the average daily trading volume during the
Lookback Period is at least 250,000 Common Shares.

          (e) The respective Warrant Holders shall exercise their Warrant rights
and purchase the appropriate Warrant Shares and pay for same within 14 business
days of the date of the Call Notice.  If the Warrant Holder fails to timely pay
the funds required by the Warrant Call, the Company may elect to cancel a
corresponding amount of this Warrant.

          (f) The Company may not exercise the right to Call this Warrant or any
part of it after the occurrence of a Non-Registration Event or Approval Default,
as defined in the Subscription Agreement, unless same were subject to cure and
cured during the stated cure period.

     11.  Maximum Exercise.  The Holder shall not be entitled to exercise, on an
          ----------------
exercise date, this Warrant in connection with that number of shares of Common
Stock which would be in excess of the sum of (i) the number of shares of Common
Stock beneficially owned by the Holder and its affiliates on an exercise date,
and (ii) the number of shares of Common Stock issuable upon the exercise of this
Warrant with respect to which the determination of this proviso is being made on
an exercise date, which would result in beneficial ownership by the Holder and
its affiliates of more

                                       8
<PAGE>

than 9.99% of the outstanding shares of Common Stock of the Company on such
exercise date. For the purposes of the proviso to the immediately preceding
sentence, beneficial ownership shall be determined in accordance with Section
13(d) of the Securities Exchange Act of 1934, as amended, and Regulation 13d-3
thereunder. Subject to the foregoing, the Holder shall not be limited to
aggregate exercises which would result in the issuance of more than 9.99%. The
restriction described in this paragraph may be revoked upon 75 days prior notice
from the Holder to the Company. The Holder may allocate which of the equity of
the Company deemed beneficially owned by the Holder shall be included in the
9.9% amount described above and which shall be allocated to the excess above
9.99%.

     12.  Warrant Agent.  The Company may, by written notice to the each holder
          -------------
of the Warrant, appoint an agent for the purpose of issuing Common Stock (or
Other Securities) on the exercise of this Warrant pursuant to Section 1,
exchanging this Warrant pursuant to Section 7, and replacing this Warrant
pursuant to Section 8, or any of the foregoing, and thereafter any such
issuance, exchange or replacement, as the case may be, shall be made at such
office by such agent.

          -------------------------------
the books of the Company, the Company may treat the registered holder hereof as
the absolute owner hereof for all purposes, notwithstanding any notice to the
contrary.

     14.  Notices, etc.  All notices and other communications from the Company
          ------------
to the holder of this Warrant shall be mailed by first class registered or
certified mail, postage prepaid, at such address as may have been furnished to
the Company in writing by such holder or, until any such holder furnishes to the
Company an address, then to, and at the address of, the last holder of this
Warrant who has so furnished an address to the Company.

     15.  Miscellaneous. This Warrant and any term hereof may be changed,
          -------------
waived, discharged or terminated only by an instrument in writing signed by the
party against which enforcement of such change, waiver, discharge or termination
