    This Registration Statement covers the registration of (i) up to 5,750,000
units ("Units"), including Units to be issued to cover over-allotments, if any,
each Unit consisting of one share of Class A Common Stock, $.0001 par value
("Common Stock"), of Advanced Aerodynamics & Structures, Inc., a Delaware
corporation (the "Company"), one redeemable Class A Warrant ("Class A Warrant")
and one redeemable Class B Warrant ("Class B Warrant"), for sale by the Company
in an underwritten public offering and (ii) an additional 3,500,000 Class A
Warrants (the "Selling Securityholders' Class A Warrants"), for sale by the
holders thereof (the "Selling Securityholders"), 3,500,000 Class B Warrants (the
"Selling Securityholders' Class B Warrants") underlying the Selling
Securityholders' Class A Warrants and 7,000,000 shares of Class A Common Stock
(the "Selling Securityholders' Stock") underlying the Selling Securityholders'
Class A Warrants and the Selling Securityholders' Class B Warrants, all for
resale from time to time by the Selling Securityholders subject to the
contractual restriction that the Selling Securityholders may not sell the
Selling Securityholders' Class A Warrants for specified periods after the
closing of the underwritten offering. The Selling Securityholders' Class A
Warrants, the Selling Securityholders' Class B Warrants and the Selling
Securityholders' Stock are sometimes collectively referred to herein as the
"Selling Securityholders' Securities."
 
    The complete Prospectus relating to the underwritten offering follows
immediately after this Explanatory Note. Following the Prospectus for the
underwritten offering are pages of the Prospectus relating solely to the Selling
Securityholders' Securities, including alternative front and back cover pages
and sections entitled "Concurrent Public Offering," "Plan of Distribution" and
"Selling Securityholders" to be used in lieu of the sections entitled
"Concurrent Offering" and "Underwriting" in the Prospectus relating to the
underwritten offering. Certain sections of the Prospectus for the underwritten
offering, such as "Use of Proceeds" and "Dilution," will not be used in the
Prospectus relating to the Selling Securityholders' Securities.

INFORMATION CONTAINED HEREIN IS SUBJECT TO COMPLETION OR AMENDMENT. A
REGISTRATION STATEMENT RELATING TO THESE SECURITIES HAS BEEN FILED WITH THE
SECURITIES AND EXCHANGE COMMISSION. THESE SECURITIES MAY NOT BE SOLD NOR MAY
OFFERS TO BUY BE ACCEPTED PRIOR TO THE TIME THE REGISTRATION STATEMENT BECOMES
EFFECTIVE. THIS PROSPECTUS SHALL NOT CONSTITUTE AN OFFER TO SELL OR THE
SOLICITATION OF AN OFFER TO BUY NOR SHALL THERE BE ANY SALE OF THESE SECURITIES
IN ANY STATE IN WHICH SUCH OFFER, SOLICITATION, OR SALE WOULD BE UNLAWFUL PRIOR
TO REGISTRATION OR QUALIFICATION UNDER THE SECURITIES LAWS OF ANY SUCH STATE.

PROSPECTUS
 
                                5,000,000 UNITS
                    ADVANCED AERODYNAMICS & STRUCTURES, INC.
            CONSISTING OF 5,000,000 SHARES OF CLASS A COMMON STOCK,
5,000,000 REDEEMABLE CLASS A WARRANTS AND 5,000,000 REDEEMABLE CLASS B WARRANTS
 
    Each unit ("Unit") offered by Advanced Aerodynamics & Structures, Inc. (the
"Company") consists of one share of Class A Common Stock, $.0001 par value (the
"Class A Common Stock"), one redeemable Class A Warrant (the "Class A Warrant")
and one redeemable Class B Warrant (the "Class B Warrant"). The Class A Warrants
and Class B Warrants (collectively, the "Warrants") will be transferable
separately immediately upon issuance. Each Class A Warrant entitles the holder
to purchase one share of Class A Common Stock and one Class B Warrant at an
exercise price of $6.50, subject to adjustment, until the fifth anniversary of
the date of this Prospectus. Each Class B Warrant entitles the holder to
purchase one share of Class A Common Stock at an exercise price of $8.75,
subject to adjustment, until the fifth anniversary of the date of this
Prospectus. The Class A Warrants and the Class B Warrants are subject to
redemption, commencing one year from the date of this Prospectus, by the Company
at a price of $.05 per Warrant on 30 days written notice if the closing bid
price of the Class A Common Stock for 30 consecutive trading days ending within
15 days of the notice of redemption of the Warrants averages in excess of $12.00
per share with respect to the Class A Warrants and $15.00 per share with respect
to the Class B Warrants (subject to adjustment in each case). See "Description
of Securities."
 
    The Class A Common Stock is one of four classes of the Company's Common
Stock (which are collectively referred to herein as the "Common Stock"). The
various classes of the Company's Common Stock are essentially identical, except
that the Class B Common Stock, $.0001 par value per share (the "Class B Common
Stock"), and the Class E-1 Common Stock, $.0001 par value per share (the "Class
E-1 Common Stock"), and the Class E-2 Common Stock, $.0001 par value per share
(the "Class E-2 Common Stock") have five votes per share and the Class A Common
Stock has one vote per share on all matters upon which stockholders may vote.
Each share of Class B Common Stock is convertible into one share of Class A
Common Stock at any time at the option of the holder and automatically upon the
sale or transfer thereof commencing 13 months after the date of this Prospectus.
Upon completion of this offering (the "Offering"), the holders of Class B Common
Stock and Class E-1 Common Stock and Class E-2 Common Stock (collectively, the
"Class E Common Stock") will control approximately 86% of the total voting power
of the Company and will therefore be able to elect all of the Company's
directors and control the Company. See "Description of Securities--Common
Stock."
 
    Prior to the Offering, there has been no public market for the Units, the
Common Stock, or the Warrants, and there can be no assurance that such a market
will develop after the completion of the Offering. The Company has filed an
application to list the Class A Common Stock, the Class A Warrants and the Class
B Warrants on the Nasdaq National Market and the Units on the Nasdaq SmallCap
Market. See "Underwriting" for a discussion of factors considered in determining
the initial public offering price. FOR INFORMATION CONCERNING A SECURITIES AND
EXCHANGE COMMISSION INVESTIGATION RELATING TO D.H. BLAIR INVESTMENT BANKING
CORP. (THE "UNDERWRITER"), SEE "RISK FACTORS" AND "UNDERWRITING."
 
    The registration statement of which this Prospectus is a part also covers
the offering for resale by certain securityholders (the "Selling
Securityholders") of 3,500,000 Class A Warrants (the "Selling Securityholders'
Class A Warrants"), 3,500,000 Class B Warrants (the "Selling Securityholders'
Class B Warrants") underlying the Selling Securityholders' Class A Warrants and
7,000,000 shares of Class A Common Stock issuable upon the exercise of the
Selling Securityholders' Class A and Class B Warrants. See "Concurrent
Securities Offering." The Selling Securityholders' Class A Warrants and the
securities underlying such warrants are sometimes collectively referred to in
this Prospectus as the "Selling Securityholders' Securities." The Company will
not receive any of the proceeds from the sale of the Selling Securityholders'
Securities. The Selling Securityholders' Class A Warrants are issuable upon the
closing of the Offering to the Selling Securityholders upon the automatic
conversion of 3,500,000 bridge warrants (the "Bridge Warrants") acquired by them
in the Company's private placement completed in August 1996 (the "Bridge
Financing"). The Selling Securityholders have agreed with the Company not to
sell the Selling Securityholders' Class A Warrants for at least 90 days after
the closing of the Offering and have agreed to sell only certain specified
percentages of such warrants during the period from 91 to 270 days after such
closing. In addition, the Selling Securityholders have agreed not to exercise
the Selling Securityholders' Class A Warrants for one year after the closing of
the Offering. See "Concurrent Securities Offering." Sales of any of the Selling
Securityholders' Securities, or even
<PAGE>
the potential of such sales at any time, may have an adverse effect on the
market prices of the securities offered hereby. Unless the context otherwise
requires, all references to the Warrants shall include the Selling
Securityholders' Warrants.

"DESCRIPTION OF SECURITIES."
 
                                  THE COMPANY
 
    The Company is a development stage company organized 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
United States Federal Aviation Administration ("FAA") with respect to a
non-pressurized, single-engine propjet aircraft powered by a Pratt & Whitney
engine (the "JETCRUZER 450"). The Company intends to modify the JETCRUZER-TM-
450 to develop a six-seat (including pilot), pressurized version of such
aircraft for commercial sale (the "JETCRUZER 500") which, the Company
anticipates, will takeoff and land in less than 1,000 feet, be able to fly at
approximately 30,000 feet above sea level, and have a high cruise speed of
approximately 350 mph and a range of approximately 1,600 miles.
 
    The Company believes that it will need to amend its current Type Certificate
to develop the JETCRUZER 500 for commercial sale as a result of certain design
changes and modifications required to be made to the aircraft to improve its
performance and capabilities and to remove a number of limitations imposed on
the Type Certificate by the FAA as a result of the aircraft's early stage of
development. The Company currently anticipates that it can obtain an amendment
to its Type Certificate during the approximately 18 to 24 months following the
Offering and commence commercial production of the JETCRUZER 500 soon
thereafter. There can be no assurance, however, that obtaining such amendment
will not take longer than anticipated, that the Company will not be required to
obtain a new type certificate for the aircraft, or that the Company will not
experience unforeseen expense or delay in certifying and commercializing the
JETCRUZER 500.
 
    The Company's proposed aircraft are based on a canard wing design in which a
smaller wing is installed in front of the aircraft's main wing. The Company
believes that this design provides for improved safety margins, including
increased lift, spin resistance and a lower stall speed, and increased ride
comfort as compared to more conventional aircraft designs. The engine and
propeller of the Company's aircraft are located at the rear of the fuselage,
thus providing the passengers with a quieter ride. In addition, the Company's
aircraft are designed to incorporate lightweight graphite composite in the
fuselage and aluminum in the main wings, which, when combined with the canard
wing, will, in the Company's opinion, enhance the performance of the aircraft by
increasing cruising distance and fuel efficiency and thereby lowering operating
expenses.
 
    The Company's objective is to become a market leader in the sale of small
business aircraft. To achieve this objective, the Company intends to focus on
the performance, efficiency and safety of its proposed aircraft. The Company's
strategy is to capitalize on a perceived current lack of relatively low-priced,
high-performance aircraft by developing, certifying, manufacturing and marketing
aircraft which outperform competitive aircraft at a reduced cost. 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 the market for its proposed aircraft will consist
primarily of foreign and domestic corporations, as well as, to a lesser extent,
private individuals and governmental entities. The
 
                                       3
<PAGE>
Company intends to develop direct marketing programs to target potential
customers and to market its aircraft through in-house sales representatives,
trade publications, aircraft trade shows and independent distributors and
agents.
 
    The Company has also initiated the development of two additional aircraft,
the JETCRUZER 650, a stretched twelve seat version of the JETCRUZER 500, and the
STRATOCRUZER-Registered Trademark- 1250, a twelve passenger twin engine jet
aircraft anticipated to fly at approximately 42,000 feet above sea level, have a
maximum cruise speed of 500 mph, and a range of 3,700 miles. The continued
development of these aircraft, including obtaining the requisite regulatory
approvals, will require substantial financing in addition to the proceeds
obtained from the Offering. Accordingly, there can be no assurance that such
aircraft will ever become available for commercial sale.
 
    The Company has incurred operating losses in each of its fiscal years to
date and expects that operating losses will continue for the foreseeable future.
No assurance can be given that the JETCRUZER 500, if successfully developed, or
any other aircraft which the Company may develop, will meet with market
acceptance or that the Company will achieve substantial sales revenue or operate
profitably.
 
    The Company's principal executive offices and design facilities are located
at 3060 Airport Way, Long Beach, California 90806. The Company's telephone
number is (310) 988-2088.
 
                              THE RECAPITALIZATION
 
    The Company was incorporated in Delaware in July 1996 and is the successor
by merger to Advanced Aerodynamics and Structures, Inc., a California
corporation incorporated in January 1990. Unless the context requires otherwise,
or as otherwise indicated, all references to the Company include the predecessor
company. Pursuant to the Agreement of Merger between the Company and its
predecessor, each share of the predecessor's common stock and preferred stock
outstanding prior to the merger was converted into approximately .056 shares of
Class B Common Stock, approximately .111 shares of Class E-1 Common Stock and
approximately .111 shares of Class E-2 Common Stock. The foregoing transactions
are collectively referred to in this Prospectus as the "Recapitalization." All
share and per share data set forth in this Prospectus have been restated to
reflect the Recapitalization.

                                  RISK FACTORS
 
    THE SECURITIES OFFERED HEREBY ARE HIGHLY SPECULATIVE IN NATURE AND INVOLVE A
HIGH DEGREE OF RISK, AND ONLY THOSE WHO CAN BEAR THE RISK OF THE LOSS OF THEIR
ENTIRE INVESTMENT SHOULD PURCHASE SUCH SECURITIES. PROSPECTIVE INVESTORS SHOULD
CAREFULLY CONSIDER, ALONG WITH THE OTHER INFORMATION CONTAINED IN THIS
PROSPECTUS, THE FOLLOWING CONSIDERATIONS AND RISKS IN EVALUATING AN INVESTMENT
IN THE COMPANY.
 
    DEVELOPMENT STAGE COMPANY; EARLY STAGE OF PRODUCT DEVELOPMENT; NO ASSURANCE
OF SUCCESS; NO COMMERCIAL OPERATIONS.  The Company is in the development stage
and has not commenced any commercial operations or received any operating
revenues. Potential investors should be aware of the problems, delays, expenses
and difficulties encountered by an enterprise in the Company's stage of
development, many of which may be beyond the Company's control. These include,
but are not limited to, unanticipated problems relating to product development,
testing, initial and continuing regulatory compliance, manufacturing costs,
production and assembly, the competitive and regulatory environment in which the
Company plans to operate, marketing problems and additional costs and expenses
that may exceed current estimates. The Company has been engaged primarily in
research and development since its inception and has not completed the
development of the JETCRUZER 500. There can be no assurance that the Company
will be able to successfully develop the JETCRUZER 500 or any of its other
proposed aircraft, that the Company will be granted, or if granted, will be able
to maintain the necessary regulatory approvals to produce and sell its proposed
aircraft, that the Company's aircraft will prove to be commercially viable or
successfully marketed, or that the Company will ever achieve significant
revenues. See "Plan of Operations" and "Business."
 
    ACCUMULATED DEFICIT; WORKING CAPITAL DEFICIT; HISTORY OF LOSSES; EXPECTATION
OF SUBSTANTIAL FUTURE LOSSES. To date, the Company has incurred significant
losses. At June 30, 1996, the Company had an accumulated deficit of
approximately $22,286,000 and a working capital deficit of approximately
$2,888,000. The Company incurred net losses of approximately $2,767,000 and
$1,688,000 for the fiscal years ended December 31, 1994 and 1995, respectively,
and has incurred a net loss of $1,346,000 for the six months ended June 30,
1996. Such losses have resulted principally from significant costs associated
with the design, development and certification of the JETCRUZER 450 aircraft.
The Company expects to incur further losses for the foreseeable future due to
significant costs associated with amending its FAA Type Certificate,
establishing manufacturing facilities capable of producing aircraft on a
commercial scale, manufacturing its proposed aircraft and obtaining the
necessary regulatory approvals relating thereto, and marketing and selling its
proposed aircraft. See "Business." There can be no assurance that sales of the
Company's aircraft will ever generate sufficient revenues to fund its continuing
operations, that the Company will generate positive cash flow from its
operations, or that the Company will attain or thereafter sustain profitability
in any future period. See "Plan of Operations" and "Use of Proceeds."
 
    UNCERTAINTY AS TO ABILITY TO CONTINUE AS A GOING CONCERN.  The report of the
Company's independent accountants contains an explanatory paragraph that
describes an uncertainty as to the ability of the Company to continue as a going
concern. Among the factors cited by the independent accountants as raising doubt
as to the Company's ability to continue as a going concern is the Company's need
for additional financing and that the Company has suffered recurring losses
during the development stage and has a working capital deficit and net
stockholders' deficit. See Report of Independent Accountants.
 
    UNCERTAINTY OF MARKET ACCEPTANCE OF AIRCRAFT; LACK OF ESTABLISHED MARKET FOR
AIRCRAFT.  The Company's business is dependent on market acceptance of its
proposed aircraft. To date, the Company has made only limited attempts to sell
its aircraft. There can be no assurance that, after the initiation of
significant marketing and sales efforts, the Company's aircraft will be accepted
by the marketplace. The Company's ability to successfully market the JETCRUZER
500 and any other aircraft it may develop will depend in part upon the Company
convincing potential customers of the price, performance and safety advantages
of its aircraft as compared to competitive aircraft having a more conventional
design and appearance. The canard design is unusual in the aircraft industry,
and there can be no assurance that potential customers
 
                                       8
<PAGE>
will accept such design. Historically, sales of other manufacturers' aircraft
having an unconventional design and appearance have been disappointing, although
such poor sales may be related to other factors. Further, as a new manufacturer
without an established reputation, the Company would be particularly vulnerable
to financial and reputational harm in the event of an occurrence that aroused
concern regarding the safety or airworthiness of the Company's aircraft,
including but not limited to, an accident or other incident involving an
aircraft manufactured by the Company. Although the Company has received
indications of interest to purchase the JETCRUZER 450 (which the Company no
longer intends to market and sell) and the JETCRUZER 500, a number of which are
supported by a nominal deposit, at any time prior to the commencement of the
manufacture of a customer's aircraft, the deposit will be returned at the
customer's request. See "Business--Competition" and "--Marketing, Distribution
and Service."
 
    REGULATORY UNCERTAINTY.  The Company intends to amend its Type Certificate
with respect to the JETCRUZER 450 to include the JETCRUZER 500, although there
can be no assurance that the FAA will not require application for a new type
certificate for the JETCRUZER 500. In addition, the Company will be required to
obtain an amendment to its Type Certificate or a new type certificate if and
when it proceeds with development of the JETCRUZER 650. The Company will be
required to obtain a new type certificate if and when it proceeds with
development of the STRATOCRUZER 1250. Obtaining a new or amended FAA type
certificate can be difficult, costly, and time consuming. There can be no
assurance that the Company will be successful in obtaining a new type
certificate or amendments to its existing Type Certificate for its proposed
aircraft, or that, if one or more new or amended type certificates are obtained,
they will not be subject to conditions which may adversely affect the use of the
proposed aircraft for their intended purpose. In the event that the FAA
determines that a new type certificate is required for any of the Company's
proposed aircraft (including the JETCRUZER 500), the time and cost of obtaining
such certification may be substantial, may render it impossible for the Company
to complete such certification and may have an adverse effect on the Company's
operations.
 
    The Company will also need to obtain an FAA production certificate for the
commercial production of its aircraft and airworthiness certificates for
individual aircraft upon the completion of manufacture. There can be no
assurance that the Company will be able to obtain a production certificate for
its planned aircraft models, or airworthiness certificates for individual
aircraft, and therefore there can be no assurance that the Company will be able
to produce and sell 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 was in doubt. If the FAA were to suspend or
revoke the Company's type or production certificate 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 requirement that the Company
develop appropriate design changes at the Company's expense. 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 liabilities. See "Business--Government
Regulation."
 
    LIMITED PRODUCTION CAPABILITIES; LACK OF MANUFACTURING EXPERIENCE.  The
Company has produced only three JETCRUZER 450 aircraft in the course of
obtaining its FAA Type Certificate and has not yet manufactured any other
aircraft or any aircraft on a commercial scale. The manufacture of aircraft is a
complex and exacting process and will require the Company to attract and retain
experienced personnel to develop a manufacturing capability and to comply with
extensive government standards with respect to its proposed aircraft and the
process by which they are manufactured. There can be no assurance that the
Company will be able to successfully implement large scale production
operations, attract and retain experienced personnel or obtain and maintain the
necessary regulatory approvals to commence and continue its manufacturing
operations. The Company intends to finance a substantial portion of the cost to
establish such a manufacturing facility through mortgage financing, industrial
development bonds and/or
 
                                       9
<PAGE>
other similar means. There can be no assurance, however, that the Company will
be able to obtain such financing in order to establish a facility capable of
producing the Company's proposed aircraft. See "Use of Proceeds," "Plan of
Operations" and "Business."
 
    LIMITED PRODUCT LINE; POSSIBLE FUTURE DECLINE IN SALES OF
AIRCRAFT.  Initially, the JETCRUZER 500 is intended to be the Company's only
product available for commercial sale. Accordingly, the operating results of the
Company and the future development of additional products will depend
substantially upon the successful sale of the Company's JETCRUZER 500, as to
which there can be no assurance. Moreover, if there is a downturn in the market
for general aviation aircraft due to economic, political or other reasons, the
Company would not be able to rely on sales of other products to offset the
downturn. For example, sales of personal and recreational aircraft declined
significantly during the 1980's and early 1990's, and it is possible that sales
of business aircraft could decline in the future. Furthermore, if a potential
purchaser is experiencing an economic downturn or is for any other reason
seeking to limit its capital expenditures, the high unit selling price of a new
aircraft may result in such potential purchaser deferring its purchase or
electing to purchase a pre-owned aircraft or a lower priced aircraft. Further,
since the Company intends to rely on the sale of a relatively small number of
high unit selling price aircraft to provide substantially all of its revenue,
small decreases in the number of aircraft delivered in any year may have a
material negative effect on the results of operations for that year. In
addition, small changes in the number and timing of deliveries of, and receipt
of payments on, new aircraft may have a material effect on the Company's
liquidity. See "Business--Industry Background" and "--Proposed Products."
 
    COMPETITION.  The Company's aircraft will compete with other aircraft that
have comparable characteristics and capabilities. Most of the Company's
competitors, including Cessna Aircraft Co. (maker of the Caravan), Socata (maker
of the TBM), Pilatus (maker of the PC-12), Raytheon Aircraft Co. (Beechcraft)
(maker of the King Air) and New Piper Aircraft Corp. (maker of the Malibu
Mirage), 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, and
such competitors may introduce such aircraft and aircraft changes prior to the
anticipated delivery of the Company's first aircraft, which is not expected for
at least two years. The Company's ability to compete effectively may be
adversely affected by the ability of these competitors to devote greater
resources to the sales and marketing of their products than are available to the
Company. In addition, the Company will need to convince potential customers of
the advantages of its aircraft as compared to competitors' aircraft having a
more conventional design and appearance. There can be no assurance that future
technological advances will not result in competitive aircraft with improved
characteristics and capabilities that could adversely affect the Company's
business. The Company's aircraft may also compete with used aircraft which
become available in the resale market at prices sufficiently lower to offset
deficits in performance, if any, as compared to the Company's aircraft. See
"Business-- Competition."
 
    NEED FOR ADDITIONAL FINANCING.  The Company believes that the net proceeds
from the Offering will be sufficient to meet its cash requirements for
approximately 18 to 24 months following consummation of the Offering; however,
there can be no assurance that the Company will not require additional financing
prior to that time or that, if required, additional financing will be available
on acceptable terms or at all. Specifically, if the FAA determines that a new
type certificate is required for the JETCRUZER 500, the time lost to obtain such
new type certificate may be substantial. In addition, following such 18 to 24
month period, if the Company has not completed the development of the JETCRUZER
500, received the required regulatory approvals, and successfully commenced
sales of its aircraft, the Company may need to obtain additional financing.
Further, the Company intends to rely on mortgage financing, industrial
development bonds or other similar financing in connection with the
establishment of a new manufacturing facility. The Company has no binding
commitments from any third parties to provide funds to the Company, and there
can be no assurance that additional financing will be available on terms
acceptable to
 
                                       10
<PAGE>
the Company, if at all. Failure to obtain such additional financing would have a
material adverse effect on the Company's business and prospects and could
require the Company to severely limit or cease its operations. See "Use of
Proceeds," "Plan of Operations" and the Financial Statements and the Notes
thereto.
 
    RELIANCE ON SINGLE SOURCE SUPPLIERS.  The Company will be dependent on
certain suppliers of products in order to manufacture its aircraft. In
particular, the Company will be dependent on Pratt & Whitney to supply the
propjet engine for the JETCRUZER 500. The Company has no contractual right to
obtain any specified number of engines from Pratt & Whitney. Should the
Company's ability to obtain the requisite number of engines be limited for any
lengthy period of time or the cost of such engines increase, the Company's
ability to produce and sell aircraft could be materially and adversely affected.
In addition, the failure of other 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. Further, a
significant amount of time has elapsed since the Company has obtained materials
and components from many of its suppliers. Accordingly, at such time as the
Company is ready to commence the manufacture of its aircraft, the prices to
obtain such materials and components may have changed and a number of suppliers
may need to be replaced. The Company's inability to obtain supplies to
manufacture its products would have a material adverse effect on the Company's
business prospects, operations and financial condition. See
"Business--Suppliers."
 
    INSURANCE AND PRODUCT LIABILITY EXPOSURE.  Because 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, the Company could be subject to lawsuits involving product liability
claims, which lawsuits may involve claims for substantial sums. Although the
Company intends to obtain comprehensive product liability insurance prior to the
commencement of commercial sales of its aircraft, such insurance can be
expensive, subject to various coverage exclusions and may not be obtainable by
the Company in the future on terms acceptable to the Company 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.
 
    FLUCTUATIONS IN QUARTERLY OPERATING RESULTS.  The Company expects to 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 due to, for example, unanticipated shipment rescheduling or
cancellations, supplier delays in the delivery of component parts or unexpected
manufacturing difficulties, could have a material and adverse effect on the
Company's financial position and results of operations for that quarter.
 
    In addition, the Company's intention to expand its manufacturing
capabilities and the need for continued investment by the Company in research,
development, engineering, and marketing will limit the Company's ability to
reduce expenses in response to any such decrease in sales. Moreover, because the
indications of interest received by the Company from potential customers will be
subject to cancellation or rescheduling by the customer prior to the
commencement of construction of the customer's aircraft, a backlog of orders at
any particular date will not necessarily be representative of actual sales for
any succeeding period. If the Company's anticipated level of revenues is not
achieved for a particular period, the Company's operating results could be
adversely affected by its inability to reduce costs. The impact of these and
other factors on the Company's operating results in any future period cannot be
accurately forecast. See "Plan of Operations."
 
    RISKS OF INTERNATIONAL OPERATIONS.  The Company intends to market and sell
its proposed aircraft to foreign customers. Accordingly, the Company will be
subject to all of the risks inherent in international operations, including work
stoppages, transportation delays and interruptions, political instability or
conflict between countries in which the Company may do business, foreign
currency fluctuations, economic
 
                                       11
<PAGE>
disruptions, differences in airworthiness and certification standards imposed by
foreign authorities, the imposition of tariffs and import and export controls,
changes in governmental policies (including United States trade policy) and
other factors, including other foreign laws and regulations, which could have an
adverse effect on the Company's business. With respect to international sales
that are denominated in U.S. dollars, an increase in the value of the U.S.
dollar relative to foreign currencies can increase the effective price of, and
reduce demand for, the Company's products relative to competitive products
priced in the local currency. These international trade factors may, under
certain circumstances, materially and adversely impact demand for the Company's
products or the Company's ability to sell its aircraft in particular countries
or deliver its products in a timely manner or at a competitive price, which in
turn may have an adverse impact on the Company's relationships with its
customers. In addition, foreign certification or equivalent approval is required
prior to importing an aircraft into a foreign country, and no assurance can be
given that the Company will receive such certification or equivalent approval in
any country. The Company's success will depend in part upon its ability to
obtain and maintain foreign certifications or equivalent approvals and manage
international marketing, sales and service operations. See "Business--Marketing,
Distribution and Service" and "--Government Regulation--Foreign Certi-
fication."
 
    DEPENDENCE ON KEY PERSONNEL; NEED FOR ADDITIONAL MANAGEMENT PERSONNEL.  The
Company's success to date has depended in large part on the skills and efforts
of Dr. Carl Chen, the Company's Chairman and Chief Executive Officer and, to a
lesser extent, on the skills and efforts of Mr. Gene Comfort, the Company's
Executive Vice President, and Mr. William Leeds, the Company's former Senior
Vice President, who has agreed to rejoin the Company upon the closing of the
Offering. See "Management-- Directors and Executive Officers." The Company's
future success will depend to a significant extent on its ability to identify
and hire certain other key employees on a timely basis. The Company is seeking
to hire personnel to complete its management team in connection with the
contemplated expansion of its operations. Competition for highly-skilled
business, product development, technical and other personnel is intense, and
there can be no assurance that the Company will be successful in recruiting new
personnel or in retaining any of its existing personnel. The Company will
experience increased costs in order to retain and attract skilled employees. The
Company's failure to attract additional qualified employees on a timely basis or
at all or to retain the services of key personnel could have a material adverse
effect on the Company's operating results and financial condition. See
"Management."
 
    LIMITED SALES AND MARKETING EXPERIENCE.  The Company's operating results
will depend to a large extent on its ability to successfully market and sell its
aircraft. The Company currently has limited marketing capabilities and needs to
hire additional sales and marketing personnel. The Company intends to use a
portion of the proceeds of the Offering to expand its marketing activities and
to hire additional sales and marketing personnel. There can be no assurance that
the Company will be able to recruit, train or retain qualified personnel to sell
and market its products or that it will develop a successful sales and marketing
strategy. The Company also has very limited marketing experience. There can be
no assurance that any marketing efforts undertaken by the Company will be
successful or will result in any significant sales of its products. See
"Business--Marketing, Distribution and Service" and "Management."
 
    RISKS OF PLANNED GROWTH.  The Company plans to significantly expand its
operations during the fourth quarter of 1996 and throughout 1997, which could
place a significant strain on its limited personnel, financial and other
resources. The Company intends to expand its manufacturing capabilities and
ultimately commence commercial manufacture of its aircraft. There can be no
assurance that the Company's efforts to conduct manufacturing activities will be
successful or that the Company will be able to satisfy commercial scale
production requirements on a timely and cost-effective basis. The Company's
ability to manage this growth, should it occur, would require significant
expansion of its engineering, production, marketing and sales capabilities and
personnel. There can be no assurance that the Company will be able to find
qualified personnel to fill such additional engineering, production, and sales
and marketing positions or be able to successfully manage a larger sales and
marketing organization. See "Business."
 
                                       12
<PAGE>
    CONTROL BY INSIDERS; OWNERSHIP OF SHARES HAVING DISPROPORTIONATE VOTING
RIGHTS.  Upon completion of the Offering, Dr. Carl Chen, the Company's Chairman
and Chief Executive Officer, and C.M. Cheng, a Director of the Company, will
beneficially own, or have voting control over, shares of the Company's capital
stock representing approximately 86% of the total voting power of the Company.
Accordingly, they will continue to be able to elect at least a majority of the
Company's directors and thereby direct the policies of the Company after
completion of the Offering. Furthermore, the disproportionate vote afforded the
shares of Class B Common Stock and Class E Common Stock could also serve to
impede or prevent a change of control of the Company. As a result, potential
acquirors may be discouraged from seeking to acquire control of the Company
through the purchase of Class A Common Stock, which could have a depressive
effect on the market price of the Company's securities. See "Principal
Stockholders."
 
    LIMITATION ON OFFICERS' AND DIRECTORS' LIABILITIES UNDER DELAWARE
LAW.  Pursuant to the Company's Certificate of Incorporation, and as authorized
under applicable Delaware law, directors and officers of the Company are not
liable for monetary damages for breach of fiduciary duty, except (i) in
connection with a breach of the duty of loyalty, (ii) for acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation of
law, (iii) for dividend payments or stock repurchases illegal under Delaware law
or (iv) for any transaction in which a director has derived an improper personal
benefit. See "Management--Limitation of Liability and Indemnification Matters."
 
    CHARGE TO INCOME IN THE EVENT OF CONVERSION OF PERFORMANCE SHARES.  The
Performance Shares will be subject to redemption by the Company at a price of
$.01 per share if the Company does not attain certain earnings or share price
levels. In the event the Company attains certain earnings or share price levels,
the Performance Shares will be automatically converted into shares of Class B
Common Stock. In the event any Performance Shares held by officers, directors,
employees or consultants of the Company are converted into Class B Common Stock,
compensation expense will be recorded for financial reporting purposes in an
amount equal to the fair value of the shares at the time such conversion occurs.
Therefore, in the event the Company attains any of the earnings thresholds or
the Company's Class A Common Stock meets certain minimum bid prices required for
the conversion of the Performance Shares, the Company will recognize a
substantial charge to earnings during the period in which such conversion occurs
as compensation expense to the Company, which would have the effect of
increasing the Company's loss or reducing or eliminating its earnings, if any,
at such time. Although the amount of compensation expense recognized by the
Company will not affect the Company's cash flow or liquidity, it may have a
depressive effect on the market price of the Company's securities. See
"Description of Securities--Common Stock."
 
    POSSIBLE ADVERSE EFFECTS OF AUTHORIZATION OF PREFERRED STOCK; ANTI-TAKEOVER
PROVISIONS.  The Company's Certificate of Incorporation authorizes the issuance
of a maximum of 5,000,000 shares of preferred stock on terms which may be fixed
by the Company's Board of Directors without stockholder action. The terms of any
series of preferred stock, which may include priority claims to assets and
dividends and special voting rights, could adversely affect the rights of
holders of the Common Stock. The issuance of preferred stock could make the
possible takeover of the Company or the removal of management of the Company
more difficult, discourage hostile bids or control of the Company in which
stockholders may receive premiums for their shares of Class A Common Stock or
otherwise dilute the rights of holders of Class A Common Stock. See "Description
of Securities--Preferred Stock."
 
    PORTION OF NET PROCEEDS TO BE USED TO REPAY BRIDGE NOTES; CHARGES ARISING
FROM DEBT DISCOUNT AND DEBT ISSUANCE COSTS.  Approximately $7,000,000 of the net
proceeds of the Offering will be used to repay in full the Bridge Notes. As a
result, the proceeds from the Offering available for the Company to meet its
ongoing operating needs and expansion plans will be correspondingly reduced. See
"Use of Proceeds." Upon completion of the Offering and repayment of the Bridge
Notes, a non-recurring charge of approximately $1,065,000 representing the
unamortized debt discount and issuance costs incurred in connection with the
Bridge Financing will be charged to operations in the quarter in which the
Offering is completed. See "Plan of Operations."
 
                                       13

    SHARES AVAILABLE FOR FUTURE SALE; REGISTRATION RIGHTS.  Future sales of
Common Stock by existing stockholders pursuant to Rule 144 under the Securities
Act of 1933, as amended (the "Securities Act"), pursuant to the Concurrent
Securities Offering or otherwise, could have an adverse effect on the price of
the Company's securities. Pursuant to the Concurrent Securities Offering,
3,500,000 Selling Securityholders' Class A Warrants and the underlying
securities have been registered for resale concurrently with the Offering,
subject to a contractual restriction that the Selling Securityholders not sell
any of the Selling Securityholders' Class A Warrants for at least 90 days from
the closing of the Offering and, during the period from 91 to 270 days after the
closing of the Offering, only sell specified percentages of such Selling
Securityholders' Class A Warrants. Upon the sale of the 5,000,000 Units offered
hereby, the Company will have outstanding 15,000,000 shares of Common Stock,
5,000,000 Class A Warrants and 5,000,000 Class B Warrants (15,750,000 shares of
Common Stock, 5,750,000 Class A Warrants and 5,750,000 Class B Warrants if the
Underwriter's over-allotment option is exercised in full). The shares of Class A
Common Stock, Class A Warrants and Class B Warrants sold in the Offering will be
freely tradeable without restriction under the Securities Act, unless acquired
by "affiliates" of the Company as that term is defined in the Securities Act.
The remaining 10,000,000 outstanding shares of Common Stock are "restricted
securities" within the meaning of Rule 144 under the Securities Act. Pursuant to
Rule 144, virtually all of these restricted shares would be eligible for resale
commencing 90 days following the date of this Prospectus. However, 2,000,000 of
the 10,000,000 outstanding shares are Class B Common Stock and thus may not be
sold until thirteen months after the date of this Prospectus. In addition, the
remaining 8,000,000 of the outstanding shares are Class E Common Stock, which
shares are not currently transferable and are subject to redemption by the
Company for a nominal consideration if the Company does not meet certain income
or stock price levels, and are convertible into Class B Common Stock if the
Company does meet such levels. The holders of the Unit Purchase Option have
certain demand and "piggyback" registration rights covering their securities.
The exercise of such rights could involve substantial expense to the Company.
Sales of Common Stock, or the possibility of such sales, in the public market
may adversely affect the market price of the securities offered hereby. See
"Concurrent Securities Offering," "Description of Securities," "Shares Eligible
for Future Sale" and "Underwriting."
 
    EFFECT OF OUTSTANDING OPTIONS AND WARRANTS.  Upon sale of the 5,000,000
Units offered hereby, the Company will have outstanding 5,000,000 Class A
Warrants to purchase 5,000,000 shares of Class A Common Stock and 5,000,000
Class B Warrants for $6.50 per share (subject to adjustment in certain
circumstances) and 5,000,000 Class B Warrants to purchase 5,000,000 shares of
Class A Common Stock at $8.75 per share (subject to adjustment in certain
circumstances) (or 5,750,000 Class A Warrants and 5,750,000 Class B Warrants if
the Underwriter's over-allotment option is exercised in full). In addition, the
Company will have outstanding 3,500,000 Selling Securityholders' Class A
Warrants to purchase 3,500,000 shares of Class A Common Stock and 3,500,000
Class B Warrants (which are exercisable for 3,500,000 shares of Class A Common
Stock), the Unit Purchase Option to purchase an aggregate of 2,000,000 shares of
Class A Common Stock assuming exercise of the underlying Warrants, and 500,000
shares of Class A Common Stock reserved for issuance under the Option Plan,
under which options to purchase 110,000 shares are outstanding at an exercise
price of $5.00 per share. Holders of such options and warrants may exercise them
at a time when the Company would otherwise be able to obtain additional equity
capital on terms more favorable to the Company. Moreover, while these options
are outstanding, the Company's ability to obtain financing on favorable terms
may be adversely affected. See "Management" and "Description of Securities."
 
    IMMEDIATE AND SUBSTANTIAL DILUTION.  Purchasers of the Units offered hereby
will incur immediate and substantial dilution in the proforma net tangible book
value of the Class A Common Stock included in the Units, estimated to be
approximately $3.65 per share or approximately 73% of the public offering price
per share (allocating no value to the Warrants). Additional dilution to public
investors, if any, may result to the extent that the Warrants, the Unit Purchase
Option or outstanding options and warrants are exercised at a time when the net
tangible book value per share of Common Stock exceeds the exercise price of any
such securities. See "Dilution."
 
                                       14
<PAGE>
    ARBITRARY DETERMINATION OF OFFERING PRICE; ABSENCE OF PUBLIC MARKET AND
POSSIBLE VOLATILITY OF STOCK PRICE. The initial public offering price of the
Units and the exercise prices and other terms of the Warrants have been
arbitrarily determined by negotiation between the Company and the Underwriter
and do not necessarily bear any relationship to the Company's assets, net worth
or other established criteria of value. The exercise and redemption prices of
the Warrants should not be construed to imply or predict any increase in the
market price of the Class A Common Stock. See "Underwriting." No public market
for the securities has existed prior to the Offering. No assurance can be given
that an active trading market in the Company's securities will develop after
completion of the Offering or, if developed, that it will be sustained. No
assurance can be given that the market price of the Company's securities will
not fall below the initial public offering price. The Company believes factors
such as quarterly fluctuations in financial results and announcements of new
technology or products or regulatory developments in the aircraft industry may
cause the market price of the Company's securities to fluctuate, perhaps
substantially. These fluctuations, as well as general economic conditions, such
as recessions or high interest rates, may adversely affect the market price of
the securities.
 
    POSSIBLE DELISTING OF SECURITIES FROM THE NASDAQ STOCK MARKET.  Although
application has been made to list the Company's Class A Common Stock, Class A
Warrants and Class B Warrants on The Nasdaq National Market and the Units on the
Nasdaq SmallCap Market, and the Company believes it will satisfy the listing
requirements of Nasdaq following completion of the Offering, the Company will
have to maintain certain minimum financial requirements for continued inclusion
on Nasdaq. If the Company is unable to satisfy Nasdaq's maintenance
requirements, the Company's securities may be delisted from Nasdaq. In such
event, trading, if any, in the Units, Class A Common Stock and Warrants would
thereafter be conducted in the over-the-counter markets in the so-called "pink
sheets" or the NASD's "Electronic Bulletin Board." Consequently, the liquidity
of the Company's securities could be impaired, not only in the number of
securities which could be bought and sold, but also through delays in the timing
of the transactions, reductions in the number and quality of security analysts'
and the news media's coverage of the Company, and lower prices for the Company's
securities than might otherwise be attained.
 
    RISK OF LOW-PRICE STOCKS.  If the Company's securities were to be delisted
from Nasdaq, they could become subject to Rule 15g-9 under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), which imposes additional
sales practice requirements on broker-dealers which sell such securities to
persons other than established customers and "accredited investors" (generally,
individuals with net worths in excess of $1,000,000 or annual incomes exceeding
$200,000, or $300,000 together with their spouses). For transactions covered by
this rule, a broker-dealer must make a special suitability determination for the
purchaser and have received the purchaser's written consent to the transaction
prior to sale. Consequently, the rule may adversely affect the ability of
broker-dealers to sell the Company's securities and may adversely affect the
ability of purchasers in the Offering to sell any of the securities acquired
hereby in the secondary market.
 
    Commission regulations define a "penny stock" to be any non-Nasdaq equity
security that has a market price (as therein defined) of less than $5.00 per
share or with an exercise price of less than $5.00 per share, subject to certain
exceptions. For any transaction involving a penny stock, unless exempt, the
rules require delivery, prior to any transaction in a penny stock, of a
disclosure schedule prepared by the Commission relating to the penny stock
market. Disclosure is also required to be made about commissions payable to both
the broker-dealer and the registered representative and current quotations for
the securities. Finally, monthly statements are required to be sent disclosing
recent price information for the penny stock held in the account and information
on the limited market in penny stocks.
 
    The foregoing penny stock restrictions will not apply to the Company's
securities if such securities are listed on Nasdaq and have certain price and
volume information provided on a current and continuing basis or if the Company
meets certain minimum net tangible assets or average revenue criteria. There can
be no assurance that the Company's securities will qualify for exemption from
these restrictions. In any event, even if the Company's securities were exempt
from such restrictions, it would remain subject to
 
                                       15
<PAGE>
Section 15(b)(6) of the Exchange Act, which gives the Commission the authority
to prohibit any person that is engaged in unlawful conduct while participating
in a distribution of a penny stock from associating with a broker-dealer or
participating in a distribution of a penny stock, if the Commission finds that
such a restriction would be in the public interest. If the Company's securities
were subject to the rules on penny stocks, the market liquidity for the
Company's securities could be severely adversely affected.
 
    CURRENT PROSPECTUS AND STATE REGISTRATION REQUIRED TO EXERCISE
WARRANTS.  The Warrants included in the Units offered hereby will be immediately
detachable and separately tradeable. Although the Units will not knowingly be
sold to purchasers in jurisdictions in which the Units are not registered or
otherwise qualified for sale, purchasers who reside in or move to jurisdictions
in which the securities underlying the Warrants are not so registered or
qualified during the period that the Warrants are exercisable may buy Units (or
the Warrants included therein) in the aftermarket. In this event, the Company
would be unable to issue securities to those persons desiring to exercise their
Warrants unless and until the underlying securities could be registered or
qualified for sale in the jurisdictions in which such purchasers reside, or
unless an exemption from such qualification exists in such jurisdictions. No
assurance can be given that the Company will be able to effect any such required
registration or qualification.
 
    Additionally, purchasers of the Units will be able to exercise the Warrants
included therein only if a current prospectus relating to the securities
underlying the Warrants is then in effect under the Securities Act and such
securities are qualified for sale or exempt from qualification under the
applicable securities or "blue sky" laws of the states in which the various
holders of the Warrants then reside. Although the Company has undertaken to use
reasonable efforts to maintain the effectiveness of a current prospectus
covering the securities underlying the Warrants, no assurance can be given that
the Company will be able to do so. The value of the Warrants may be greatly
reduced if a current prospectus covering the securities issuable upon the
exercise of the Warrants is not kept effective or if such securities are not
qualified or exempt from qualification in the states in which the holders of the
Warrants then reside.
 
    ADVERSE EFFECT OF POSSIBLE REDEMPTION OF WARRANTS.  The Warrants are subject
to redemption by the Company commencing one year from the date of this
Prospectus, on at least 30 days' prior written notice, if the average closing
bid price of the Class A Common Stock for 30 consecutive trading days ending
within 15 days of the date on which the notice of redemption is given exceeds
$12.00 per share with respect to the Class A Warrants and $15.00 per share with
respect to the Class B Warrants. If the Warrants are redeemed, holders of
Warrants will lose their right to exercise the Warrants, except during such
30-day notice of redemption period. Upon the receipt of a notice of redemption
of the Warrants, the holders thereof would be required to: (i) exercise the
Warrants and pay the exercise price at a time when it may be disadvantageous for
them to do so, (ii) sell the Warrants at the then current market price (if any)
when they might otherwise wish to hold the Warrants, or (iii) accept the
redemption price, which is likely to be substantially less than the market value
of the Warrants at the time of redemption. See "Description of Securities--
Redeemable Warrants."
 
    NO DIVIDENDS.  The Company has paid no dividends to its stockholders since
its inception and does not plan to pay dividends in the foreseeable future. The
Company intends to reinvest earnings, if any, in the development and expansion
of its business. See "Dividend Policy."
 
    POSSIBLE ADVERSE EFFECT ON LIQUIDITY OF THE COMPANY'S SECURITIES DUE TO
INVESTIGATION BY THE SECURITIES AND EXCHANGE COMMISSION OF THE UNDERWRITER AND
D.H. BLAIR & CO.  The Securities and Exchange Commission (the "Commission") is
conducting an investigation concerning various business activities of the
Underwriter and D.H. Blair & Co., Inc. ("Blair & Co."), a selling group member
that will distribute substantially all of the Units offered hereby. The
investigation appears to be broad in scope, involving numerous aspects of the
Underwriter's and Blair & Co.'s compliance with the Federal securities laws and
compliance with the Federal securities laws by issuers whose securities were
underwritten by the Underwriter or Blair & Co., or in which the Underwriter or
Blair & Co. made over-the counter markets, persons associated with the
Underwriter or Blair & Co., such issuers and other persons. The Company has been
advised by the
 
                                       16
<PAGE>
Underwriter that the investigation has been ongoing since at least 1989 and that
it is cooperating with the investigation. The Underwriter cannot predict whether
this investigation will ever result in any type of formal enforcement action
against the Underwriter or Blair & Co. or, if so, whether any such action might
have an adverse effect on the Underwriter or the securities offered hereby. The
Company has been advised that Blair & Co. intends to make a market in the
securities following the Offering. An unfavorable resolution of the Commission's
investigation could have the effect of limiting such firm's ability to make a
market in the Company's securities, which could adversely affect the liquidity
or price of such securities. See "Underwriting."
 
    POSSIBLE RESTRICTIONS ON MARKET MAKING ACTIVITIES IN THE COMPANY'S
SECURITIES.  The Underwriter has advised the Company that Blair & Co. intends to
make a market in the Company's securities. Rule 10b-6 under the Exchange Act
will prohibit Blair & Co. from engaging in any market-making activities with
regard to the Company's securities for the period from nine business days (or
such other applicable period as Rule 10b-6 may provide) prior to any
solicitation by the Underwriter of the exercise of Warrants until the later of
the termination of such solicitation activity or the termination (by waiver or
otherwise) of any right that the Underwriter may have to receive a fee for the
exercise of Warrants following such solicitation. As a result, Blair & Co. may
be unable to provide a market for the Company's securities during certain
periods while the Warrants are exercisable. In addition, under applicable rules
and regulations under the Exchange Act, any person engaged in the distribution
of the Selling Securityholders' Warrants may not simultaneously engage in
market-making activities with respect to any securities of the Company for the
applicable "cooling off" period (at least two and possibly nine business days)
prior to the commencement of such distribution. Accordingly, in the event the
Underwriter or Blair & Co. is engaged in a distribution of the Selling
Securityholders' Warrants, neither of such firms will be able to make a market
in the Company's securities during the applicable restrictive period. Any
temporary cessation of such market-making activities could have an adverse
effect on the market prices of the Company's securities. See "Underwriting."

                                USE OF PROCEEDS
 
    The net proceeds from the sale of the 5,000,000 Units offered hereby, after
deducting the underwriting discount and commissions and other estimated expenses
of the Offering, are anticipated to be approximately $22,047,923 ($25,460,423 if
the Underwriter's over-allotment option is exercised in full). The Company
expects the net proceeds to be utilized approximately as follows:

(1) Represents the aggregate principal amount of Bridge Notes issued in the
    Bridge Financing completed by the Company in August 1996, together with
    estimated accrued interest through October 28, 1996. The Bridge Notes bear
    interest at the rate of 10% per annum and mature on the earlier of the
    closing of the Offering or August 30, 1997. The proceeds of the Bridge Notes
    were and are being used to repay bank and other outstanding indebtedness,
    loans from officers and directors, accrued compensation and past due
    accounts payable and for working capital. See "Plan of Operations" and
    "Certain Transactions."
 
(2) Represents the cost of obtaining an amendment of the Company's FAA Type
    Certificate to include the JETCRUZER 500, including the cost of equipment,
    tooling, dies, and jigs necessary to manufacture the JETCRUZER 500, the
    costs of static and flight testing, and the cost of hiring, training, and
    employing personnel necessary to obtain such amendment. The Company expects
    that certain of the equipment and tooling which will be acquired or created
    by the Company in amending its Type Certificate will also be used to
    manufacture the JETCRUZER 500 for commercial sale.
 
(3) Includes the purchase of additional production tools and the in-house
    duplication of existing tooling, jigs and dies for commercial production.
 
(4) Represents a portion of the costs of establishing an appropriate
    manufacturing facility. The Company estimates that the total cost of this
    facility will be approximately $7,000,000 and anticipates funding the
    remaining portion of such facility through mortgage financing, industrial
    development bonds and/ or other similar means. In the event that the Company
    is unable to fully fund the cost of such facility from such sources, it may
    be necessary to use the proceeds allocated to working capital for such
    purpose or the Company may determine to lease a facility until such funds
    become available. See "Plan of Operations."
 
(5) Includes the cost of sales materials, advertising, trade shows and hiring,
    training and employing additional sales and marketing personnel.
 
(6) Represents working capital reserves and general and administrative expenses,
    including those related to the financial and accounting functions of the
    Company, management information systems, insurance and hiring, training and
    employing administrative, financial, and accounting personnel.
 
    The foregoing represents the Company's best estimate of its allocation of
the net proceeds of the Offering during the next 18 to 24 months. This estimate
is based upon the current status of the Company's business and upon certain
assumptions, including, primarily, assumptions that the Company's development of
the JETCRUZER 500 will occur as projected and that the Company will obtain the
necessary regulatory
 
                                       18
<PAGE>
approvals on a timely basis. The amounts actually expended for each purpose set
forth above, other than repayment of the Bridge Notes, may vary significantly in
the event that any of these assumptions prove to be inaccurate. Future events,
including the problems, delays, expenses and difficulties frequently encountered
by development stage companies, changes in economic, regulatory or competitive
conditions or the Company's proposed business, the results of the Company's
sales and marketing activities, or the inability to obtain regulatory approvals
as anticipated, may make changes in the anticipated allocation of funds
necessary or desirable. The Company reserves the right to change its use of
proceeds in response to unanticipated events or opportunities. In addition, the
Company may use funds allocated to working capital to acquire or invest in
complementary businesses or products. The Company does not currently have any
plans, agreements, or commitments with respect to any possible acquisition.
 
    The Company anticipates, based on its current plans and assumptions
regarding its future operations, that the net proceeds of the Offering will be
sufficient to satisfy the Company's cash requirements for at least the next 18
to 24 months. If the Company's estimates prove to be incorrect, however, then
during such period, the Company may have to seek additional sources of
financing, reduce operating costs and/or curtail growth plans. In addition,
following such period, if the Company has not completed the development of the
JETCRUZER 500, received the required regulatory approvals, and commenced
commercial sales of the JETCRUZER 500, the Company may need to obtain additional
financing. No assurances can be given that additional sources of financing would
be available to the Company under those circumstances; and, if the Company were
unable to obtain needed financing, the Company's business would be materially
and adversely affected. See "Plan of Operations."
 
    Prior to their use, the net proceeds of the Offering will be invested in
short-term, high-grade interest-bearing investments or accounts. Any proceeds
received upon exercise of the Underwriter's over-allotment option, the Warrants
or the Selling Securityholders' Warrants will be added to working capital.
 
                                DIVIDEND POLICY
 
    The Company has not, to date, paid any dividends. The Company has no current
plans to pay dividends and intends to retain earnings, if any, for working
capital purposes. Any future determination as to the payment of dividends by the
Company will depend upon the Company's results of operations, capital
requirements, and financial condition and other factors deemed relevant by the
Company's Board of Directors.

                                    DILUTION
 
    THE FOLLOWING DISCUSSION AND TABLES ALLOCATE NO VALUE TO THE WARRANTS WHICH
ARE A PART OF THE UNITS.
 
    Dilution represents the difference between the initial public offering price
per share paid by the purchasers in the Offering and the net tangible book value
per share immediately after completion of the Offering. Pro forma net tangible
book value per share represents the net tangible assets of the Company (total
assets less total liabilities and intangible assets) divided by the number of
shares of Common Stock outstanding giving retroactive effect to the
Recapitalization in July 1996 and pro forma effect to the issuance in August
1996 of the Bridge Notes, net of debt discount. At June 30, 1996, the Company
had a pro forma net tangible book value deficit of $571,000, or approximately
$0.06 per share ($0.29 per share if the Performance Shares are excluded). After
giving effect to the issuance of the 5,000,000 Units offered hereby at an
assumed public offering price of $5.00 per Unit and the Company' s receipt of
the estimated net proceeds therefrom and the use of a portion of the net
proceeds to repay the Bridge Notes (including interest), the pro forma net
tangible book value of the Company, as adjusted at June 30, 1996, would be
$20,199,000, or approximately $1.35 per share ($2.89 per share if the
Performance Shares were excluded). This would result in an immediate dilution to
investors in the Offering of $3.65, or 73%, per share ($2.11, or 42%, per share
if the Performance Shares were excluded), and the aggregate increase in the pro
forma net tangible book value to present stockholders would be $1.41 per share
($3.18 per share if Performance Shares are excluded), as illustrated by the
following table:

</TABLE>
 
- ------------------------
 
(1) If the over-allotment option is exercised in full, the pro forma net
    tangible book value per share after the Offering would be approximately
    $1.56, resulting in dilution to new investors in the Offering of $3.44, or
    69%, per share.
 
    The following table sets forth on a pro forma basis the differences between
existing stockholders and new investors in the Offering with respect to the
number of shares of Common Stock purchased from the Company, the total
consideration paid to the Company and the average price per share paid by
existing stockholders and by new investors at an initial public offering price
of $5.00 per Unit:

BRIDGE FINANCING
 
    In August 1996, the Company completed the Bridge Financing of an aggregate
of $7,000,000 principal amount of Bridge Notes and 3,500,000 Bridge Warrants in
which it received net proceeds of approximately $6,195,000 (after expenses of
such offering). The Bridge Notes are payable, together with interest at the rate
of 10% per annum, on the earlier of one year from the issuance of the Bridge
Notes or the closing of the Offering. See "Use of Proceeds," "Plan of
Operations" and "Certain Transactions." Commencing in August 1997, the Bridge
Warrants entitle the holders thereof to purchase one share of Class A Common
Stock. However, the Bridge Warrants will be exchanged automatically on the
closing of the Offering for the Selling Securityholders' Warrants, each of which
will be identical to the Class A Warrants included in the Units offered hereby.
The Selling Securityholders' Warrants have been registered for resale in the
Registration Statement of which this Prospectus is a part, subject to the
contractual restriction that the Selling Securityholders have agreed not to
exercise the Selling Securityholders' Warrants for a period of one year from the
closing of the Offering and not to sell the Securityholders' Warrants except
after specified periods commencing 90 days after the closing date of the
Offering. See "Concurrent Securities Offering."

                               PLAN OF OPERATIONS
 
    The following discussion and analysis should be read in conjunction with the
financial statements and notes thereto appearing elsewhere in this Prospectus.
 
GENERAL
 
    The Company is a development stage enterprise organized to design, develop,
manufacture and market propjet and jet aircraft intended primarily for business
use. Since its inception, the Company has been engaged principally in research
and development of its proposed aircraft. 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. As a
result, the Company has not generated any operating revenues to date and has
incurred losses from such activities. The Company expects losses to continue
until such time, if ever, as its sales of aircraft generate sufficient revenues
to cover operating costs.
 
    At such time, if ever, as the Company commences the commercial sale of its
proposed 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 expects to receive progress payments during the
construction of aircraft and final payments upon the delivery of aircraft.
Therefore, construction or delivery delays near the end of a particular quarter,
due to, for example, shipment reschedulings, 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 the 18 to 24 months following the Offering, the Company intends to
focus its efforts in the following areas:
 
    - To complete the development of the JETCRUZER 500, including, among other
      things, adding a larger engine, pressurization, environmental systems,
      de-icing capability and autopilot certification. See "Business--Proposed
      Aircraft."
 
    - To obtain an amendment to its Type Certificate to include the JETCRUZER
      500, including the manufacture of FAA conformed models of the JETCRUZER
      500 and static and flight testing. See "Business--Government Regulation."
 
    - To establish an appropriate manufacturing facility capable of producing
      the JETCRUZER 500 on a commercial scale, including the establishment of a
      production line in such facility and the acquisition of production
      inventory and additional items of equipment, tooling and computer hardware
      and software systems. See "Business--Facilities."
 
    - To obtain a production certificate from the FAA and commence commercial
      production of the JETCRUZER 500. See "Business--Government Regulation."
 
    - To expand its sales and marketing staff and increase its marketing efforts
      with respect to the JETCRUZER 500. See "Business--Marketing, Distribution
      and Service."
 
    - To increase its engineering, manufacturing and administrative staff in
      anticipation of increased development and production activities. See
      "Business--Employees."
 
                                       24
<PAGE>
    The Company believes that the net proceeds of the Offering will be
sufficient to finance its plan of operations for at least the 18 to 24 months
following the Offering, based upon the current status of its business
operations, its current plans and current economic and industry conditions. See
"Use of Proceeds." If the Company's estimates prove to be incorrect, however,
then during such period the Company may have to seek additional sources of
financing, reduce operating costs and/or curtail growth plans. See "--Liquidity
and Capital Resources."
 
RESULTS OF OPERATIONS
 
    The Company has not generated any revenues from operations. For the period
from inception (January 26, 1990) through June 30, 1996, the Company incurred a
net loss of $22,286,000, $2,767,000 and $1,688,000 of which was incurred during
the years ended December 31, 1994 and December 31, 1995, respectively, and
$845,000 and $1,346,000 of which was incurred during the six months ended June
30, 1995 ("1995 six months") and June 30, 1996 ("1996 six months") respectively.
These 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.
 
    Research and development expenses have consisted primarily of the costs of
personnel, facilities and materials and equipment required to conduct the
Company's development activities. Such expenses aggregated $13,636,000 from
inception through June 30, 1996, $1,088,000 of which was incurred in 1994 and
none of which was incurred in 1995 or in the 1996 six months. 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, the JETCRUZER 650 and the
STRATOCRUZER. Research and development expenses will increase in the fourth
quarter of 1996 and in 1997 as the Company accelerates the development of the
JETCRUZER 500 and amends its Type Certificate with respect thereto.
 
    General and administrative expenses have consisted primarily of
administrative salaries and benefits, rent, marketing expenses, insurance and
other administrative costs. Such expenses aggregated $6,632,000 from inception
through June 30, 1996, $1,239,000 and $1,453,000 of which were incurred in 1994
and 1995, respectively, and $769,000 and $1,169,000 of which were incurred in
the 1995 six months and the 1996 six months, respectively. General and
administrative expenses have increased since 1994 primarily due to increased
compensation expenses payable to the Company's executive officers who were
engaged principally in capital raising and marketing activities. Such increases
were partially offset by decreases in rent, insurance, employee payroll and
other administrative costs occasioned by the Company's limited development
activities during the period. General and administrative expenses are expected
to increase substantially in the fourth quarter of 1996 and in 1997 due to the
addition of personnel and other resources to support increased administrative,
marketing, and development activities. See "--Liquidity and Capital Resources."
 
    Interest expense has consisted primarily of interest expended by the Company
for bank and private financing. Interest expense aggregated $1,373,000 from
inception through June 30, 1996, $156,000 and $262,000 of which were incurred in
1994 and 1995, respectively, and $103,000 and $185,000 of which were incurred in
the 1995 six months and the 1996 six months, respectively. See "--Liquidity and
Capital Resources."
 
    In 1994, the Company incurred a $357,000 loss on disposal of assets, which
was a result of the disposal of certain tooling equipment in connection with the
Company's relocation in September 1994.
 
    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, 1995, the Company had a federal tax net operating loss
carryforward of approximately $17,000,000 which, if unused, will expire in
varying amounts in years 2005 through 2010 and a state tax net operating loss
carryforward of approximately $3,000,000 which, if unused, will expire in
various amounts in years 1996 through 2000.

    At December 31, 1995, the Company had federal and state research and
development ("R&D") credit carryforwards of approximately $1,169,000 and
$468,000, respectively. The federal R&D credit carryforwards will expire in
years 2005 through 2010. The state R&D credit carryforwards can be carried
forward indefinitely. See Note 4 of Notes to Financial Statements.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    At June 30, 1996, the Company had a working capital deficit of $2,888,000,
an accumulated deficit of $22,286,000 and a negative net worth of $1,044,000.
Since its inception in January 1990, the Company has experienced continuing
negative cash flow from operations, which has resulted in the Company's
inability to pay certain existing liabilities in a timely manner. The Company
has financed its operations through private fundings of equity and debt.
 
    Prior to mid-1994, the activities of the Company were financed primarily by
(i) equity contributions from Mr. Song Gen Yeh and members of his immediate
family, who were at that time directors and principal stockholders of the
Company, in the aggregate amount of $7,280,000 and (ii) loans in the aggregate
amount of $10,728,000 from Mr. Yeh. The loans made by Mr. Yeh were repaid
through the issuance of 598,011 shares of Class B Common Stock, 1,196,021 shares
of Class E-1 Common Stock, and 1,196,021 shares of Class E-2 Common Stock of the
Company in June 1996. Additionally, in October 1993, the Company received a loan
of $60,000, bearing interest at a rate of 12%, from SIDA Corporation ("SIDA"), a
corporation then affiliated with Dr. Carl Chen, the President and Chief
Executive Officer and a Director of the Company; and, in February and July 1994,
the Company received loans in an aggregate amount of $565,000, bearing interest
at a rate of 12%, from four individuals who were at the time not affiliated with
the Company. One of such persons, C.M. Cheng, became a Director of the Company
in June 1996. These loans were repaid in September 1996 with the proceeds of the
Bridge Financing described below. See "Certain Transactions."
 
    In the second half of 1994, the Company's expenditures decreased because
capital constraints required a reduction of the Company's development
activities. The Company's capital requirements during that period were satisfied
primarily by a loan from General Bank in the principal amount of approximately
$550,000, bearing interest at the prime rate plus 1 1/2%, which loan was
guaranteed by the Small Business Administration, the California Export Finance
Office and Dr. Chen and secured by substantially all of the Company's assets.
The Company also received an additional $50,000 loan from SIDA.
 
    During 1995 and 1996, the Company's capital requirements were met by
additional advances of $350,000 pursuant to the bank loan described above and
loans by Dr. Chen, bearing interest at a rate of 12%, in the aggregate principal
amount of $562,000. In June 1996, $336,000 of indebtedness owed by the Company
to Dr. Chen was converted into 187,118 shares of Class B Common Stock, 374,236
shares of Class E-1 Common Stock, and 374,236 shares of Class E-2 Common Stock.
 
    In September 1996, the bank loan, in the aggregate principal amount of
$900,000 plus $15,000 in accrued interest, $226,000 of the principal amount owed
to Dr. Chen, together with interest thereon of $36,000, and the loan from SIDA,
in the aggregate principal amount of $110,000 plus $31,000 in accrued interest,
were repaid with the proceeds of the Bridge Financing described below. See
"Certain Transactions."
 
    In August 1996, the Company completed the Bridge Financing of $7,000,000
principal amount of Bridge Notes and 3,500,000 Bridge Warrants (which will
automatically convert to Class A Warrants upon completion of the Offering). See
"Bridge Financing" and "Concurrent Securities Offering." The net proceeds of the
Bridge Financing were approximately $6,195,000 after deducting commissions and a
non-accountable expense allowance aggregating $805,000 paid to the placement
agent and other expenses of the Bridge Financing. The net proceeds of the Bridge
Financing were and are being used to repay bank and other outstanding
indebtedness, loans from officers and directors, accrued compensation and past
due accounts payable and as working capital. The Company has allocated a portion
of the net proceeds of the
 
                                       26
<PAGE>
Offering to repay the Bridge Notes. See "Bridge Financing," "Certain
Transactions," and "Use of Proceeds." Additionally, the Company will recognize a
charge to operations of approximately $1,065,000, representing the combined
unamortized debt discount and issuance costs arising from the Bridge Financing,
in the quarter in which the Bridge Notes are repaid.
 
    The Company expects its cash requirements to increase in the future due to
higher expenses associated with product development, the scale-up of production
(including capital investment in production equipment), implementation of a
sales and marketing program, the hiring of personnel and other anticipated
operating activities. The Company also 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. See
"Business--Marketing, Distribution and Service."
 
    The Company expects that the net proceeds of the Offering will enable it to
meet its liquidity and capital requirements for at least 18 to 24 months
following completion of the Offering, although the Company's capital
requirements are subject to numerous contingencies associated with development
stage companies. Specifically, in the event that the FAA determines that a new
type certificate is required, or if delays are encountered in amending the
current Type Certificate, the time and cost of obtaining such certification may
be substantial, may render it impossible for the Company to complete such new or
amended certification and may therefore have a material and adverse effect on
the Company's operations. Further, following such 18 to 24 month period, if the
Company has not completed the development of the JETCRUZER 500, received the
required regulatory approvals and successfully commenced commercial sales of its
aircraft, the Company may require additional funding to fully implement its
proposed business plan. The Company has no commitments from any third parties
for any future funding, and there can be no assurance that the Company will be
able to obtain financing in the future from bank borrowings, debt or equity
financings or other sources on terms acceptable to the Company or at all. In the
event necessary financing were not obtained, the Company would be materially and
adversely affected and might have to cease or substantially reduce operations.
 
    The Company had no material capital commitments at June 30, 1996. Following
the Offering, the Company intends to hire a number of additional employees and
to establish a larger manufacturing facility, both of which will require
substantial capital resources. The Company anticipates that it will hire
approximately 50 employees over the next six months and 150 employees over the
next 24 months, including engineers and manufacturing technicians necessary to
produce its aircraft. See "Business-- Employees." Additionally, the Company
plans to acquire, build and/or improve a larger manufacturing facility. The
Company estimates that the total cost of such facility will be approximately
$7,000,000 and has allocated approximately $1,100,000 of the proceeds of the
Offering to fund a portion of such cost. The Company anticipates funding the
remaining portion of such cost through mortgage financing, industrial
development bonds and/or other similar means. There can be no assurance,
however, that such funding will be available on terms acceptable to the Company
or at all. In the event the Company is unable to fund fully the costs of the
facility from such sources, it may utilize a portion of the proceeds from the
Offering allocated to working capital for such purpose or it may lease a
facility until adequate funds become available. See "Use of Proceeds."
 
    The Report of Independent Accountants includes an explanatory paragraph
indicating that there is substantial doubt as to the Company's ability to
continue as a going concern. See Report of Independent Accountants.

CHARGE TO INCOME IN THE EVENT OF 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, compensation expense will be recorded for financial reporting
purposes in an amount equal to the fair value of the shares at the time such
conversion occurs. 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.

OVERVIEW
 
    The Company is a development stage company organized 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 intends to modify the JETCRUZER 450 to develop a
six-seat (including pilot), pressurized version of such aircraft for commercial
sale (the "JETCRUZER 500") which, the Company anticipates, will takeoff and land
in less than 1,000 feet, be able to fly at approximately 30,000 feet above sea
level, and have a high cruise speed of approximately 350 mph and a range of
approximately 1,600 miles.
 
    The Company believes it will need to amend its Type Certificate to develop
the JETCRUZER 500 for commercial sale as a result of certain design changes and
modifications required to be made to the aircraft to improve its performance and
capabilities and to remove a number of limitations imposed on the Type
Certificate by the FAA as a result of the aircraft's early stage of development.
The Company currently anticipates that it can obtain an amendment to its Type
Certificate during the approximately 18 to 24 months following the Offering and
commence commercial production of such aircraft soon thereafter. There can be no
assurance, however, that obtaining the amendment will not take longer that
anticipated, that the Company will not be required to obtain a new type
certificate for the JETCRUZER 500, or that the Company will not experience
unforeseen expense or delay in certifying and commercializing its proposed
aircraft.
 
INDUSTRY BACKGROUND
 
    The general aviation industry comprises essentially all nonmilitary aviation
activity other than scheduled and charter 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. 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. There may be one or two engines and propellers. Turbofan
aircraft use jet propulsion to power the aircraft. There are generally two
engines on general aviation turbofan aircraft, although there may also be one or
three.
 
    Purchasers of general aviation aircraft include (i) corporations, (ii)
governments, (iii) the military, (iv) the general public and (v) 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 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. See "Business--Government Regulation."
 
    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. In 1995, approximately 581 piston
aircraft were delivered for approximately $123 million in billings;
approximately 250 propjets were
 
                                       29
<PAGE>
delivered for billings of approximately $653 million; and approximately 246 jet
aircraft were delivered, generating billings of approximately $2 billion.
 
    Total shipments of general aviation aircraft manufactured in the United
States reached a peak in 1978, when approximately 18,000 aircraft were shipped.
The number of units delivered annually has decreased since that time as a result
of a number of factors, such as the cost of aviation fuel, high interest rates,
inflation and, most importantly, an increase in negligence and product liability
claims arising from accidents involving small, personal/recreational piston
aircraft and a resulting increase in the price of manufacturer's liability
insurance. Since 1986, the number of units delivered per year from United States
manufacturers has not exceeded 1,500, and fewer than 1,000 aircraft were
delivered from United States manufacturers in each of 1992, 1993 and 1994.
 
    Although the total number of general aviation aircraft manufactured in the
United States declined from 1978 to 1994, deliveries of more expensive propjet
and jet aircraft manufactured in the United States increased, resulting in a
less substantial decline in the total dollar value of shipments of aircraft
during such period and a substantial increase in the average price of each such
aircraft delivered from 1978 through 1994. Deliveries of more costly corporate
aircraft powered by propjet or jet engines were affected to a lesser extent by
the liability and insurance coverage problems encountered by piston aircraft. In
addition, on August 17, 1994, Congress enacted the General Aviation
Revitalization Act of 1994 ("GARA"). The GARA imposes an 18-year statute of
limitations on product liability suits involving airplane manufacturers and
suppliers. Although product liability suits will not disappear, nor is it likely
that settlements will be smaller, the Company believes that the reduction to 18
years of an original equipment manufacturer's exposure to lawsuits may lower
insurance costs for the industry which may result in increased sales of aircraft
and a corresponding increase in the number of licensed pilots. Shipments of all
types of general aviation aircraft manufactured in the United States increased
from 928 units in 1994 to 1,077 units in 1995.
 
STRATEGY
 
    The Company's objective is to become a worldwide market leader in the sale
of small business aircraft. To achieve this objective, the Company intends to
focus on the performance, efficiency and safety of its proposed aircraft. The
Company's strategy is to capitalize on a perceived current lack in the
marketplace of low-priced, high-performance aircraft. The Company believes that
its ability to offer an aircraft which outperforms competitive aircraft at a
reduced cost will enable the Company to penetrate the 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, 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 reasonable cost due to the selection of a management and
manufacturing team that had prior aircraft manufacture and FAA related
experience and its ability to control overhead expenses incurred in connection
with obtaining the Type Certificate. The Company believes that it will be able
to control manufacturing costs by producing most of the tooling, jigs, dies and
molds required for the manufacture of its aircraft in-house. Also, because the
Company will produce the airframe and most of the associated components of its
aircraft in-house, it will have greater control over the production process; and
the
 
                                       30
<PAGE>
Company believes that this control will also help keep construction and
certification costs at reduced levels.
 
PROPOSED AIRCRAFT
 
    GENERAL.
 
    The Company's proposed 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 performance and
safety margins, including increased lift, spin resistance and a lower stall
speed, and increased ride comfort as compared to more conventional aircraft
designs. Management also believes that the Company's aircraft will provide
performance advantages over competitors' models, including better stall and
handling characteristics, increased speed, smoother ride, greater fuel
efficiency and lower operating expenses. See "Business--Competition."
 
    The fuselage of each aircraft will be 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 (30 foot long by
10 foot diameter) nitrogen-pressurized autoclave. The canard wing on the
JETCRUZER will be constructed of aircraft aluminum; and the canard wing on the
STRATOCRUZER, if that aircraft is developed, will be constructed of the graphite
composite. The main rear wing and the ailerons of all of the aircraft will be
constructed of aircraft aluminum skin and spar and rib construction. Flaps are
not required on the JETCRUZER because of the design and high lift capabilities
of the canard and the main wing. The engine and propeller of the Company's
JETCRUZER aircraft are located at the rear of the fuselage, thus providing
passengers with a quieter ride.
 
    JETCRUZER-TM- 500.
 
    The JETCRUZER 500 is intended to be 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 is intended to have a canard
configuration with two lift-producing surfaces and no conventional wing flaps.
The JETCRUZER 500 will be powered by a Pratt & Whitney PT6A-42A, 1,132 ESHP
propjet engine located at the rear of the aircraft. The JETCRUZER 500 is
intended to be 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 which were imposed as a result of the aircraft's early stage of
development. For example, the maximum number of occupants is presently limited
to five, as compared to the six passenger (including pilot) design configuration
of the JETCRUZER 500, and the maximum operating speed is presently limited to
178 mph, as compared to the 350 mph design speed of the JETCRUZER 500. The
Company intends to amend the Type Certificate to remove these limitations in the
course of further development and certification of the JETCRUZER 500.
 
    In order to amend the Type Certificate to include the JETCRUZER 500, a
significant amount of work remains to be performed on the aircraft by the
Company, including adding pressurization, environmental systems, de-icing
capability and autopilot certification, all of which will be necessary to
produce the JETCRUZER 500 for commercial sale. The Company currently anticipates
obtaining the amendment to its Type Certificate during the approximately 18 to
24 months after the Offering. Although it has not yet submitted its application
for amendment, it has notified the FAA of its intention to do so. There can be
no assurance, however, that obtaining such an amendment will not take longer
than anticipated, that any of the FAA limitations will be removed or that such
removal will not, in the FAA's judgment, necessitate a new type certificate,
thereby causing unforeseen expense and delay in certifying the JETCRUZER 500.
See "--Government Regulation."
 
                                       31
<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), have a cruise speed of approximately 350 mph and a stall speed of
approximately 61 knots. The Company also believes that such aircraft should be
able to climb at approximately 2,600 feet per minute, cruise at an altitude of
approximately 30,000 feet above sea level, have a range of approximately 1,600
miles and takeoff and land in less than 1000 feet. 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.
 
    Although there can be no assurance, the Company currently anticipates that
the JETCRUZER 500 will be available for commercial sale at a price of
approximately $1,300,000 approximately two years following the date of this
Prospectus. However, since the Company has not yet completed development of the
JETCRUZER 500 and has not yet established a facility for manufacturing it on a
commercial scale, both of which may be subject to unforeseen delays, the date on
which the JETCRUZER 500 is actually available for sale and its initial purchase
price could change materially.
 
    To date, the Company has made only limited test marketing attempts to sell
its aircraft. Notwithstanding these limitations, the Company has received more
than 30 written indications of interest to purchase the JETCRUZER 450 and the
JETCRUZER 500. Because the Company believes that the improved performance
characteristics associated with the JETCRUZER 500 will make it a more desirable
aircraft than the JETCRUZER 450, the Company currently intends to initially
produce only the JETCRUZER 500. Accordingly, the Company has converted all but
two of the indications of interest in the JETCRUZER 450 into indications of
interest in the JETCRUZER 500. Generally, written indications of interest are
supported by a $10,000 deposit. However, each such deposit is refundable at the
request of the purchaser at any time until the commencement of construction of
the purchaser's particular aircraft. Accordingly, there can be no assurance that
any such indications of interest will lead to the sale of an aircraft.
 
OTHER PROPOSED AIRCRAFT
 
    JETCRUZER-TM- 650.
 
    The Company currently intends to develop the JETCRUZER 650. This aircraft
will be based on the JETCRUZER 450/500 design and will have the same engine and
components as the JETCRUZER 500. However, it is intended to have a longer
fuselage which will accommodate up to twelve passengers plus a pilot. To produce
the JETCRUZER 650, the Company will need either to amend its Type Certificate or
obtain a new type certificate, as determined by the FAA.
 
    The Company anticipates that the cruise speed of the JETCRUZER 650 will be
approximately 300 miles per hour, that it will takeoff in approximately 1,800
feet, climb at a rate of 1,200 to 1,600 feet per minute and have a maximum range
of approximately 1,250 miles. The Company currently plans to offer two versions
of the JETCRUZER 650: a pressurized corporate and on-demand charter passenger
aircraft, which will cruise at approximately 30,000 feet above sea level and
have a maximum passenger seating capacity of twelve, and a non-pressurized
version for use as a utility/freight aircraft which will cruise at a lower
altitude than the pressurized version.
 
    The JETCRUZER 650 is in a very early stage of development, and the
completion of such development and the certification of such aircraft will
require substantial capital resources beyond the proceeds obtained by the
Company in the Offering. There can be no assurance, however, that the Company
will obtain the resources necessary to continue the JETCRUZER 650 program, or if
such resources are obtained, successfully develop and certify the JETCRUZER 650.
Accordingly, the Company cannot predict when, if ever, the JETCRUZER 650 will be
available for commercial sale.
 
                                       32
<PAGE>
    STRATOCRUZER-REGISTERED TRADEMARK- 1250.
 
    The Company also currently intends to develop a twin engine jet aircraft to
be called the STRATOCRUZER 1250. The STRATOCRUZER, if developed, is expected to
be a canard aircraft with three flying surfaces powered by two Williams/Rolls
Royce FJ44-2 fanjets. It will be able to seat up to 12 passengers, plus the
pilot. Based on its design and preliminary testing, it is anticipated that the
STRATOCRUZER will have a maximum cruise speed of approximately 500 mph, a range
of approximately 3,700 miles and a pressurized ceiling of approximately 42,000
feet. The STRATOCRUZER will be able to takeoff in less than 3,200 feet and land
in less than 3,000 feet. The instrumentation of the STRATOCRUZER 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's comparatively light
weight, combined with, among other things, its additional lifting surfaces, fuel
efficient engines and aerodynamic design, will give the STRATOCRUZER 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.
 
    The STRATOCRUZER is in a very early stage of development, and the completion
of such development will also require substantial capital resources beyond those
to be obtained by the Company in the Offering. Therefore, there can be no
assurance that the Company will obtain the resources necessary to continue the
STRATOCRUZER program or, if such resources are obtained, successfully develop
and certify the STRATOCRUZER. Accordingly, the Company cannot predict when, if
ever, the STRATOCRUZER will be available for commercial sale.
 
MANUFACTURING
 
    The Company has designed and 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 intends to obtain or produce additional sets
of the equipment necessary for production of the JETCRUZER 500 with the proceeds
of the Offering and acquire and/or build a manufacturing facility capable of
producing the JETCRUZER 500. See "--Facilities." The Company intends to produce
in-house nearly all of the tooling necessary for the production of its aircraft,
from master models to major jigs and fixtures. The Company believes it achieves
cost savings by manufacturing tooling itself. Additionally, nearly all airframe
assemblies and parts are intended to be produced in-house, except for special
tasks such as hydroforming, spar milling and painting. The manufacturing process
for the Company's aircraft is highly technical and requires skilled assembly
technicians. The Company intends to rehire a number of employees who assisted
the Company in the development of the JETCRUZER 450 as well as a number of
additional employees. However, no assurance can be given that former employees
of the Company or other personnel with the required skills will in fact be
available to the Company. See "Business--Employees."
 
    The equipment and procedures used by the Company for manufacturing must be
certified, and are subject to inspection and continuing oversight by the FAA.
See "Business--Government Regulation."
 
    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 designed to meet the requirements of the
military, the National Aeronautics and Space Administration ("NASA") and the
FAA. All of the Company's precision tools and gauges are certified by the
National Bureau of Standards.
 
    The Company intends to manufacture the advanced graphite composite fuselage
structure used in the construction of its aircraft in its own
computer-controlled, nitrogen-pressurized autoclave. Although not operational at
this time, 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 and in the course of certifying
 
                                       33
<PAGE>
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, as opposed to metal construction, because 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
 
    MARKETING AND DISTRIBUTION.
 
    To date, the Company has conducted limited marketing activity and has
marketed its aircraft only through test advertisements and news releases in
trade publications. Following completion of the Offering, the Company intends to
use a portion of the proceeds of the Offering to develop an in-house sales
organization and market its aircraft in a number of different territories in the
United States and abroad through trade publications, aircraft trade shows, and
independent distributors and agents.
 
    The Company's efforts will emphasize aircraft trade shows, from which it
believes a significant amount of new aircraft sales are generated. The Company
intends to participate in, among others, 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 will help introduce the Company's aircraft
to other potential purchasers and help increase overall awareness of the
Company's products. The Company also intends to promote general knowledge of the
Company's products by issuing press releases to aviation magazines and
newspapers. The Company will also use 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 intends to develop direct marketing programs to target such
corporations. The Company believes that its aircraft will also be attractive to
customers other than corporations and intends to address these markets. 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 surveillance or mapping photography, forest fire detection, and
other purposes, 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
operations of 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.
 
    The Company intends to provide 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 several domestic banks, of
which at least one provides 20-year loans for corporate aircraft. 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
("FBO's") authorized by the Company. FBO's 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
 
                                       34
<PAGE>
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 will rely on certain suppliers of products necessary to
manufacture its aircraft, including a number of different suppliers of materials
and components. In particular, the engines and the avionics will be provided by
outside manufacturers. These suppliers also produce equipment for aircraft
manufacturers other than the Company. Engines for the JETCRUZER will be
manufactured by Pratt & Whitney. Engines for the STRATOCRUZER, if that aircraft
is developed, will be manufactured by Williams/Rolls Royce. The Company has no
contractual right to obtain any specified number of engines from Pratt & Whitney
or any other manufacturer. Should the Company's ability to obtain the requisite
number of engines be limited for any lengthy period of time or the cost of such
engines increase, the Company's ability to produce and sell aircraft could be
materially and adversely affected. In addition, the failure of other 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 that competition will be based primarily
on the aircraft's price, performance and operating cost. 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.
 
    The following table lists the number of seats (including pilot), estimated
price and high cruise speed of the aircraft which the Company considers to be
the principal competitors of the JETCRUZER 500.

</TABLE>
 
    There are currently only three single engine propjet aircraft on the market
in the JETCRUZER 500 category: the Socata TBM 700, the Pilatus PC-12 and the
Cessna Caravan. The TBM 700 is a pressurized, single engine propjet of
conventional design with a Pratt & Whitney engine. It is made in France and has
passenger capacity and performance similar to the JETCRUZER 500. Its base price
is approximately $2,607,000. The Pilatus PC-12 is also a single engine propjet
of conventional design with a Pratt & Whitney engine. The Pilatus PC-12 is made
in Switzerland, has an airspeed of 310 mph and has a base price of approximately
$2,315,000. The Cessna Caravan 208B has a base price of approximately $1,493,000
and is designed primarily for hauling freight at low altitude. Its high speed is
210 mph, its landing gear does not retract, and it is not pressurized. Each of
these competitive products is a standard, one lifting-wing aircraft built
primarily from aircraft aluminum, rather than graphite.
 
                                       35
<PAGE>
    Additional competition to the JETCRUZER 500 may be provided by 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. Its approximate base price is $755,000. 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
(particularly 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, and the proposed JETCRUZER 650,
if developed, 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 due to the perception of additional safety associated
with twin-engine aircraft. Additionally, single-engine aircraft are not
permitted by FAA regulations to be used for commercial passenger revenue-paying
flights (whether on-demand charter or scheduled) in instrument conditions.
However, single engine aircraft may currently be used for revenue-paying
on-demand charter and scheduled flights under VFR (visual flight rules) provided
the pilot and aircraft meet certain FAA certification, proficiency, maintenance
and additional equipment and airworthiness requirements. See "Governmental
Regulation."
 
    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 the Company's
ability to market its proposed aircraft will not be materially adversely
affected by future technological changes or marketing initiatives on the part of
its competitors.
 
    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 purchasers who might otherwise
acquire a used aircraft by emphasizing the price, performance, technology, fuel
efficiency and operational costs advantages 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 with regard to aircraft purchased by customers
commencing on 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. In the past it has obtained other
insurance as needed, including flight test insurance for the pilots and aircraft
used during the FAA certification process.
 
                                       36
<PAGE>
GOVERNMENT REGULATION
 
    The manufacture of aircraft is subject to extensive regulation by the
Federal Aviation Administration ("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 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 intends to amend its Type Certificate with respect to the
JETCRUZER 450 to include the JETCRUZER 500, although there can be no assurance
that the FAA will not require application for a new type certificate for the
JETCRUZER 500. In addition, the Company will be required to obtain a further
amendment to its Type Certificate or a new type certificate if and when it
proceeds with development of the JETCRUZER 650. The Company will be required to
obtain a new type certificate if and when it proceeds with development of the
STRATOCRUZER 1250. Obtaining a new or amended FAA type certificate can be
difficult, costly, and time consuming. There can be no assurance that the
Company will be successful in obtaining a new type certificate or amendments to
its existing Type Certificate for its planned aircraft models, or, if granted,
will not be subject to conditions which may adversely affect the use of the
planned aircraft models for their intended purpose or the Company's operations.
In the event that the FAA determines that a new type certificate is required for
any of the Company's planned aircraft models (including the JETCRUZER 500), the
time and cost of obtaining such certification may be substantial, may render it
impossible for the Company to complete such certification and may have an
adverse effect on the Company's operations.
 
    The Company will also need to obtain an 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 inspections and
will either issue the production certificate or require that the Company modify
either or both of its quality assurance manual or the manufacturing process.
While production does not necessarily stop during the review process, a failure
to receive a production certificate would likely delay the manufacturing
process.
 
    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.
 
                                       37
<PAGE>
    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 was 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 at the Company's expense.
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.
 
    GOVERNMENT ASSISTANCE.
 
    The Company may pursue government funding or assistance in establishing its
new manufacturing facility. The Company has previously negotiated with local and
state governments regarding incentives for locating the Company's facilities in
a certain state or locality, including facility construction, tax incentives and
employee training. If the Company is able to obtain such assistance or
financing, the Company may be subject to certain restrictions on its operations,
including an inability to relocate or to obtain certain types of financing.
 
    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 counties 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 foreign countries once it has received the amendment to the Type
Certificate for the JETCRUZER 500 and has finalized a sale or distributorship in
that country.
 
    FACILITIES.
 
    The Company's executive offices and research and limited manufacturing
facilities are located in an approximately 40,000 sq. ft. building near the Long
Beach, California airport pursuant to a month to month lease at a monthly rent
of $12,000. The Company has allocated a portion of the net proceeds of the
Offering to establish a larger facility to enable the Company to expand its
manufacturing capabilities as soon as a suitable location is found. The Company
presently has no other facilities.
 
                                       38
<PAGE>
    The Company has identified several possible locations for its manufacturing
facility. The Company believes that establishment of the manufacturing facility
will take approximately 5 to 7 months and that the municipality selected by the
Company as the site of its main manufacturing facility will provide assistance
with streamlining the permit process, local licensing and other requirements.
The Company believes the cost of establishing the facility will be approximately
$7,000,000, which the Company intends to fund in part with the proceeds of the
Offering and in part through mortgage financing, industrial development bonds,
or other similar means. The total anticipated size of the facility will be
approximately 220,000 square feet, with approximately 20,000 square feet of
office space and approximately 200,000 square feet of manufacturing space. In
the event that the Company is unable to fully fund the cost of such facility,
the Company may determine to lease a facility until such funds become available.
See "Use of Proceeds" and "Plan of Operations."
 
EMPLOYEES
 
    As of September 12, 1996, the Company had five 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.
 
    The Company will require highly skilled engineers and manufacturing
technicians to complete the design of and produce the JETCRUZER 500. The Company
believes that a number of such individuals are available in Southern California
in general, and the Long Beach area in particular, as a result of recent
downsizings by large aerospace and defense contractors. In the past, the Company
has obtained the majority of its employees from this pool. However, there can be
no assurance that these individuals will remain available or that the Company
will be able to fill all necessary positions with qualified personnel.
 
    The Company intends to hire employees as needed and believes that
approximately 50 employees will be hired within six months of the closing of the
Offering. Those employees will be needed to work on obtaining the amendment to
the Company's Type Certificate, as well as to plan and prepare for the Company's
relocation to a new manufacturing facility. The Company believes that it will
require a total of approximately 150 employees within 24 months of the closing
of the Offering to produce, manufacture, market and sell the JETCRUZER 500.
 
LEGAL PROCEEDINGS
 
    The Company is party to various lawsuits relating to routine matters
considered incidental to the operation of its business. Based on the amounts in
controversy and management's evaluation of the merits of the claims after
consultation with counsel, management does not believe that the outcome of such
litigation, in the aggregate, will have a material adverse effect on the
Company.
 
    In connection with the Recapitalization in July 1996, the stockholders of
the Company had the right, within thirty days of receiving notice of the merger
which was a part of the Recapitalization, to exercise dissenters' rights and
make written demand upon the Company to purchase their shares at fair market
value. The Company did not receive any such demands within such thirty-day
period. However, one stockholder, who presently owns slightly less than 5% of
the Company's outstanding Common Stock, forwarded a letter to the Company
claiming that he did not receive sufficient information in order to exercise his
rights and that therefore the time to exercise his rights should be extended. In
addition, such stockholder has asserted that his ownership interest in the
Company has been improperly diluted. Such stockholder threatened to commence
litigation against the Company. The Company has not received any communications
from such stockholder since the expiration of the time period for notification
of the exercise of dissenters' rights.
 
    The Company believes that it has complied with the statutory requirements
with respect to the Recapitalization as well as with respect to all issuances of
its capital stock. However, there can be no assurance as to whether such
stockholder will in fact assert any such claims against the Company or whether
any such claims will be successful. The Company does not believe, however, that
any adverse outcome of claims asserted against the Company by such stockholder
would have a material adverse effect on the Company.

    The Company entered into an eight-year employment agreement (the "Chen
Employment Agreement") with Dr. Carl Chen, the Company's, Chairman, Chief
Executive Officer and President, commencing in May 1996. The Chen Employment

deemed appropriate by the Board of Directors. The Company will maintain life
insurance coverage on Dr. Chen, and Dr. Chen may name the beneficiary of such
policy. The Chen Employment Agreement also provides that he will not compete
with the Company during the term of the Agreement and for eighteen months
thereafter and that, if Dr. Chen's employment is terminated by the Company
without cause (as defined therein), he will receive up to eighteen months'
salary as severance, payable monthly commencing on the thirtieth day following
such termination without cause.
 
STOCK OPTION PLAN
 
    The Board of Directors and the stockholders of the Company have adopted and
approved the 1996 Stock Option Plan ("Stock Option Plan"). The Stock Option Plan
provides for the grant of incentive stock options ("ISOs") within the meaning of
Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"), and
non-qualified stock options ("NQSOs") to certain employees, officers, directors,
consultants and agents of the Company. The purpose of the Stock Option Plan is
to attract and retain qualified employees, agents, consultants, officers and
directors.
 
    The total number of shares of Class A Common Stock with respect to which
options may be granted under the Stock Option Plan is 500,000. The shares
subject to, and available under, the Stock Option Plan may consist, in whole or
in part, of authorized but unissued stock or treasury stock not reserved for any
other purpose. Any shares subject to an option that terminates, expires or
lapses for any reason, and any shares purchased upon exercise of an option and
subsequently repurchased by the Company pursuant to the terms of the option,
become available for grant under the Stock Option Plan.
 
    The Stock Option Plan is administered by the Board of Directors of the
Company, which determines, in its discretion, among other things, the recipients
of grants, whether a grant will consist of ISOs or NQSOs, or a combination
thereof, and the number of shares of Class A Common Stock to be subject to such
option. The Board may, in its discretion, delegate its power, duties and
responsibilities under the Stock Option Plan to a committee consisting of two or
more directors. The exercise price for ISOs must be at least 100% of the fair
market value per share of Class A Common Stock on the date of grant, as
determined by the Board. ISOs are not transferable, other than by will or the
laws of descent and distribution. NQSOs may be transferred to the optionee's
spouse or lineal descendants, subject to certain restrictions. Options may be
exercised during the holder's lifetime only by the holder or his or her guardian
or legal representative.
 
    Options may be exercisable for a term determined by the Board, which may not
be less than one year or greater than 10 years from the date of grant. Options
may be exercised only while the original optionee has a relationship with the
Company which confers eligibility to be granted options or within 90 days after
termination of such relationship with the Company, or up to six months after
death or total and permanent disability. In the event the Company terminates its
relationship with the original optionee for cause (as defined in the Stock
Option Plan), all options granted to the optionee terminate immediately.
 
    The Stock Option Plan contains certain limitations applicable only to ISOs
granted thereunder to satisfy specific provisions of the Internal Revenue Code.
For example, the aggregate fair market value, as of the date of grant, of shares
as to which an ISO becomes exercisable for the first time by an optionee during
any calendar year may not exceed $100,000. In addition, if an optionee owns more
than 10% of the Company's stock at the time the individual is granted as ISO,
the exercise price per share cannot be less than 110% of the fair market value
per share and the term of the option cannot exceed five years.
 
    Options may be paid for in cash, by check or, in certain instances, by
delivering an assignment of shares of Class A Common Stock having a value equal
to the option price, or any combination of the foregoing, as stipulated in the
option agreement entered into between the Company and the optionee. At the
discretion of the Board, the Company may loan to the optionee some or all of the
purchase price of the shares acquired upon exercise of an option granted under
the Stock Option Plan.
 
                                       43
<PAGE>
    The Board may modify, suspend or terminate the Stock Option Plan; provided,
however, that certain material modifications affecting the Stock Option Plan
must be approved by the stockholders, and any change in the Stock Option Plan
that may adversely affect an optionee's rights under an option previously
granted under the Stock Option Plan requires the consent of the optionee.
 
    As of the date of this Prospectus, the Company had granted options to
purchase 110,000 shares of Class A Common Stock at an exercise price of $5.00
per share under the Stock Option Plan. See
"--Director Compensation" and "Certain Transactions."
 
LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
    The Company's Certificate of Incorporation eliminates in certain
circumstances the liability of directors of the Company for monetary damages for
breach of their fiduciary duty as directors. This provision does not eliminate
the liability of a director (i) for breach of the director's duty of loyalty to
the Company or its stockholders, (ii) for acts or omissions by the director not
in good faith or which involve intentional misconduct or a knowing violation of
law, (iii) for willful or negligent declaration of an unlawful dividend, stock
purchase or redemption, or (iv) for transactions from which the director derived
an improper personal benefit. Such limitation of liability does not affect the
availability of equitable remedies such as injunctive relief or rescission.
 
    The Company believes that it is the position of the Commission that, insofar
as the foregoing provision may be invoked to disclaim liability for damages
arising under the Securities Act, the provision is against public policy as
expressed in the Securities Act and is therefore unenforceable.
 
    The Company has entered into indemnification agreements ("Indemnification
Agreement(s)") with each of its directors and officers. Each such
Indemnification Agreement provides that the Company will indemnify the
indemnitee against expenses, including reasonable attorneys' fees, judgements,
penalties, fines and amounts paid in settlement actually and reasonably incurred
by him in connection with any civil or criminal action or administrative
proceeding arising out of his performance of his duties as a director or
officer, other than an action instituted by the director or officer. Such
indemnification is available if the indemnitee acted in good faith and in a
manner he reasonably believed to be in or not opposed to the best interests of
the Company, and with respect to any criminal action, had no reasonable cause to
believe his conduct was unlawful. The Indemnification Agreements also require
that the Company indemnify the director or other party thereto in all cases to
the fullest extent permitted by applicable law. Each Indemnification Agreement
permits the director or officer that is party thereto to bring suit to seek
recovery of amounts due under the Indemnification Agreement and to recover the
expenses of such suit if he is successful.

                              CERTAIN TRANSACTIONS
 
    From January 1990 through December 1993, Mr. Song Gen Yeh, who was at that
time a principal stockholder and director of the Company, advanced funds to the
Company in the aggregate amount of $10,478,000. In December 1993, the Company
entered into an agreement with Mr. Yeh to repay such advances through the
issuance of 584,074 shares of Class B Common Stock, 1,168,148 shares of Class
E-1 Common Stock, and 1,168,148 shares of Class E-2 Common Stock of the Company.
Such shares were issued to Mr. Yeh in June 1996. From 1994 through 1995, Mr. Yeh

such advances were repaid by the Company through the issuance of 13,937 shares
of Class B Common Stock, 27,873 shares of Class E-1 Common Stock, and 27,873
shares of Class E-2 Common Stock. Such shares were subsequently transferred to
Harpa Limited ("Harpa"), a Cayman Islands corporation the voting stock of which
is controlled by two of Mr. Yeh's children. C.M. Cheng, a director of the
Company, is the Director of Harpa and, as such, has the power to vote the shares
of the Company's Common Stock held by Harpa. See "Principal Stockholders."
 
    In January 1990, the Company entered into a five-year agreement (the
"Management Agreement") with SIDA Corporation ("SIDA"). Dr. Carl L. Chen, the
Chairman, Chief Executive Officer and President of the Company, was, at that
time, a principal stockholder of SIDA, and the other two stockholders of SIDA
were also, at that time, stockholders of the Company. The Management Agreement
provided for annual payments to SIDA of $140,000 for management services
provided to the Company. Such agreement expired by its terms in January 1995. As

together with accrued interest of $64,000 through August 30, 1996, was paid from
the proceeds of the Bridge Financing in September 1996. In October 1993 and
February 1994, the Company obtained loans from SIDA in the aggregate principal
amount of $110,000, bearing interest at 12%. These loans, together with accrued
interest of $31,000, were repaid from the proceeds of the Bridge Financing in
September 1996.
 
    In February and July 1994, the Company received loans in an aggregate
principal amount of $565,000, bearing interest at a rate of 12%, from four

together with accrued interest of $161,000, were repaid with the proceeds of the
Bridge Financing in September 1996.
 
    In December 1994, the Company entered into a New Management Agreement (the
"New Management Agreement") with Dr. Chen which took effect in January 1995.
Pursuant to the New Management Agreement, Dr. Chen agreed to serve as the
Company's President and Chief Executive Officer. The New Management Agreement
had a term of 10 years and provided that Dr. Chen was to receive a signing bonus
of 139,365 shares of Class B Common Stock, 278,730 shares of Class E-1 Common
Stock, and 278,730 shares of Class E-2 Common Stock, an annual salary of
$350,000, and additional annual compensation payable in 147,727 shares of Class
B Common Stock, 295,454 shares of Class E-1 Common Stock, and 295,454 shares of
Class E-2 Common Stock. In May 1996, Dr. Chen agreed to terminate the New
Management Agreement. Pursuant to the New Management Agreement and in connection
with its termination, the Company issued a total of 577,823 shares of Class B
Common Stock, 1,155,647 shares of Class E-1 Common Stock, and 1,155,647 shares
of Class E-2 Common Stock to Dr. Chen. At June 30, 1996, $130,000 remained
accrued and unpaid under the New Management Agreement. This amount was paid to
Dr. Chen with the proceeds of the Bridge Financing in September 1996.
 
    In May 1996 the Company entered into an Employment Agreement with Dr. Chen
pursuant to which he agreed to serve as its Chairman, Chief Executive Officer
and President. See "Management--Employment Agreement." As of August 31, 1996,
compensation of $67,000 was accrued and unpaid under this Agreement. This amount
was paid from the proceeds of the Bridge Financing in September 1996.
 
    From September 1995 through August 1996, Dr. Chen made loans bearing
interest at a rate of 12% to the Company in the aggregate principal amount of
$562,000. In May 1996, Dr. Chen agreed to convert
 
                                       45

$336,000 of these loans into 187,118 shares of Class B Common Stock, 374,236
shares of Class E-1 Common Stock, and 374,236 shares of Class E-2 Common Stock.
The remaining $226,000 principal amount of these loans, together with $36,000 of
accrued interest, was repaid with the proceeds of the Bridge Financing in
September 1996.
 
    In 1994 and 1995, the Company obtained loans from General Bank in the
aggregate principal amount of $900,000. This loan bore interest at the prime
rate plus 1.5% and had a maturity date of October 1996. Repayment of the loan
was guaranteed by the Small Business Administration, the California Export
Finance Office and Dr. Chen and was secured by substantially all the assets of
the Company. The total outstanding balance of the loan of approximately $915,000
(including accrued interest) was repaid from the proceeds of the Bridge
Financing in September 1996.
 
    In May 1996, the Company issued 17,460 shares of Class B Common Stock,
34,919 shares of Class E-1 Common Stock, and 34,919 shares of Class E-2 Common
Stock to Gene Comfort, its Executive Vice President, in consideration of Mr.

Selling Securityholders' Class A Warrants are identical to the Class A Warrants
included in the Units offered hereby and are being issued to the Selling
Securityholders on the closing of the Offering upon the automatic conversion of
all of the Company's outstanding Bridge Warrants. All of the Selling
Securityholders' Class A Warrants issued upon conversion of the Bridge Warrants,
the Class A Common Stock and Class B Warrants issuable upon exercise of such
Class A Warrants and the Class A Common Stock issuable upon exercise of the
Class B Warrants will be registered, at the Company's expense, under the
Securities Act and are expected to become tradeable on or about the closing of
the Offering, subject to a contractual restriction that such Selling
Securityholders' Class A Warrants and underlying securities may not be sold for
at least 90 days after the closing of the Offering; and, during the period from
91 to 270 days after such closing, only certain specified percentages of such
securities may be sold. The Selling Securityholders have also agreed with the
Company not to exercise their Selling Securityholders' Class A Warrants for a
period of one year following the closing of the Offering; provided, however,
that purchasers of such Selling Securityholders' Class A Warrants are not
subject to such restrictions on exercise. After the one-year period following
the closing of the Offering or following delivery of a notice of redemption by
the Company, the Selling Securityholders may exercise the Selling
Securityholders' Class A Warrants and sell the Class B Warrants and Class A
Common Stock issuable upon exercise of their warrants without restriction if a
current prospectus relating to such Class A Common Stock is in effect and the
securities are qualified for sale. The Company will not receive any proceeds
from the sale of the Selling Securityholders' Class A Warrants. Sales of Selling
Securityholders' Class A Warrants or the securities underlying such Class A
Warrants or even the potential of such sales could have an adverse effect on the
market prices of the Units, the Class A Common Stock and the Warrants. See
"Shares Eligible For Future Sale."
 
    There are no material relationships between any of the Selling
Securityholders and the Company, nor have any such material relationships
existed within the past three years. The Company has been informed by the
Underwriter that there are no agreements between the Underwriter and any Selling
Securityholder regarding the distribution of the Selling Securityholders'
Warrants or the underlying securities.
 
    The sale of the securities by the Selling Securityholders may be effected
from time to time in transactions (which may include block transactions by or
for the account of the Selling Securityholders) in the over-the-counter market
or in negotiated transactions, a combination of such methods of sale or
otherwise. Sales may be made at fixed prices which may be changed, at market
prices prevailing at the time of sale or at negotiated prices.
 
    Selling Securityholders may effect such transactions by selling their
securities directly to purchasers, through broker-dealers acting as agents for
the Selling Securityholders or to broker-dealers who may purchase shares as
principals and thereafter sell the securities from time to time in the
over-the-counter market, in negotiated transactions or otherwise. Such
broker-dealers, if any, may receive compensation in the form of discounts,
concessions or commissions from the Selling Securityholders or the purchasers
for whom such broker-dealers may act as agents or to whom they may sell as
principals or otherwise (which compensation as to a particular broker-dealer may
exceed customary commissions).
 
    Under applicable rules and regulations under the Exchange Act, any person
engaged in the distribution of the Selling Securityholders' Class A Warrants may
not simultaneously engage in market making activities with respect to any
securities of the Company for a period of at least two (and possibly nine)
business days prior to the commencement of such distribution. Accordingly, in
the event the Underwriter or Blair & Co. is engaged in a distribution of the
Selling Securityholders' Class A Warrants, neither of such firms will be able to
make a market in the Company's securities during the applicable restrictive
period. However, neither the Underwriter nor Blair & Co. has agreed to, nor is
either of them obligated to, act as
 
                                       48
<PAGE>
a broker-dealer in the sale of the Selling Securityholders' Class A Warrants,
and the Selling Securityholders may be required, and in the event Blair & Co. is
a market maker, will likely be required, to sell such securities through another
broker-dealer. In addition, each Selling Securityholder desiring to sell
Warrants will be subject to the applicable provisions of the Exchange Act and
the rules and regulations thereunder, including without limitation Rules l0b-6
and l0b-7, which provisions may limit the timing of the purchases and sales of
shares of the Company's securities by such Selling Securityholders.
 
    The Selling Securityholders and broker-dealers, if any, acting in connection
with sales of the Selling Securityholders' Class A Warrants or the securities
underlying such Warrants may deemed to be "underwriters" within the meaning of
Section 2(11) of the Securities Act, and any commission received by them and any
profit on the resale of such securities might be deemed to be underwriting
discounts and commissions under the Securities Act.

                           DESCRIPTION OF SECURITIES
 
    The following description of the capital stock of the Company and certain
provisions of the Company's Certificate of Incorporation and Bylaws is a summary
and is qualified in its entirety by the provisions of the Certificate of
Incorporation and Bylaws, which have been filed as exhibits to the Company's
Registration Statement of which this Prospectus is a part.
 
    The authorized capital stock of the Company currently consists of 45,000,000
shares of Class A Common Stock, $.0001 par value, 10,000,000 shares of Class B
Common Stock, $.0001 par value, 4,000,000 shares of Class E-1 Common Stock,
$.0001 par value, 4,000,000 shares of Class E-2 Common Stock, $.0001 par value,
and 5,000,000 shares of Preferred Stock, $.0001 par value. As of the date of
this Prospectus, there were outstanding 2,000,000 shares of Class B Common Stock
(held of record by four stockholders), 4,000,000 shares of Class E-1 Common
Stock (held of record by four stockholders), 4,000,000 shares of Class E-2
Common Stock (held of record by four stockholders), no shares of Class A Common
Stock and no shares of Preferred Stock.
 
UNITS
 
    Each Unit offered hereby consists of one share of Class A Common Stock, one
Class A Warrant and one Class B Warrant. At any time commencing on the date of
issuance until the fifth anniversary date of this Prospectus, each Class A
Warrant will be exercisable to purchase one share of Class A Common Stock and
one Class B Warrant and each Class B Warrant will be exercisable to purchase one
share of Class A Common Stock. The Common Stock and Warrants included in the
Units are immediately transferable separately upon issuance.
 
COMMON STOCK
 
    The Class A Common Stock, Class B Common Stock, Class E-1 Common Stock and
Class E-2 Common Stock are substantially identical, except that the holders of
Class A Common Stock have the right to cast one vote, and the holders of Class B
Common Stock, Class E-1 Common Stock, and Class E-2 Common Stock have the right
to cast five votes, for each share held of record on all matters submitted to a
vote of the holders of Common Stock, including the election of directors. The
Class A Common Stock, Class B Common Stock, Class E-1 Common Stock and Class E-2
Common Stock vote together as a single class on all matters on which
stockholders may vote, including the election of directors, except when voting
by class is required by applicable law. Holders of the Class A Common Stock,
Class B Common Stock, Class E-1 Common Stock and Class E-2 Common Stock have
equal ratable rights to dividends from funds legally available therefor, when,
as and if declared by the Board of Directors and are entitled to share ratably,
as a single class, in all of the assets of the Company available for
distribution to the holders of shares of Common Stock upon the liquidation,
dissolution or winding up of the affairs of the Company. Except as described
herein, no pre-emptive, subscription, or conversion rights pertain to the Common
Stock and no redemption or sinking fund provisions exist for the benefit
thereof. All outstanding shares of Common Stock are, and those shares of Class A
Common Stock offered hereby will be duly authorized, validly issued, fully paid
and nonassessable.
 
    As a consequence of their ownership of Common Stock and the enhanced voting
power of the Class B Common Stock, Class E-1 Common Stock, and Class E-2 Common
Stock, the current stockholders of the Company will continue to control a
majority of the voting power of the Company following completion of the Offering
and, accordingly, will be able to elect all of the Company's directors. This
difference in voting rights and consequent increase in the voting power of the
Class E-1 Common Stock, Class E-2 Common Stock and Class B Common Stock has an
anti-takeover effect, in that the existence of the Class E-1 Common Stock, Class
E-2 Common Stock and Class B Common Stock may make the Company a less attractive
target for a hostile takeover bid or render more difficult or discourage a
merger proposal, an
 
                                       50
<PAGE>
unfriendly tender offer, a proxy contest, or the removal of incumbent
management, even if such transactions were favored by the stockholders of the
Company other than the holders of Class E-1 Common Stock, Class E-2 Common Stock
and Class B Common Stock. Thus, the stockholders of the Company may be deprived
of an opportunity to sell their shares at a premium over prevailing market
prices in the event of a hostile takeover bid. Those seeking to acquire the
Company through a business combination will be compelled to consult first with
the holders of the Class E-1 Common Stock, Class E-2 Common Stock and Class B
Common Stock in order to negotiate the terms of such a business combination.
Additionally, any such proposed business combination would have to be approved
by the Board of Directors, which may be under the control of the holders of the
Class E-1 Common Stock, Class E-2 Common Stock and Class B Common Stock; and, if
stockholder approval were required, the approval of the holders of the Class E-1
Common Stock, Class E-2 Common Stock and Class B Common Stock would be necessary
before any such business combination could be consummated.
 
    PERFORMANCE SHARES
 
    The Company's Certificate of Incorporation provides that the Class E-1 and
the Class E-2 Common Stock is redeemable by the Company at a price of $.01 per
share unless the Company meets certain income or share price thresholds. If the
thresholds are met, the Performance Shares will be automatically converted into
shares of Class B Common Stock. The Performance Shares are not assignable or
transferable other than upon death, by operation of law, or to related parties
who agree to be bound by the restrictions on the Performance Shares set forth in
the Company's Certificate of Incorporation.
 
    (a) The 4,000,000 shares of outstanding Class E-1 Common Stock will be
automatically converted into Class B Common Stock if, and only if, one or more
of the following conditions are met:
 
        (i) the Company's net income before provision for income taxes and
    exclusive of any extraordinary earnings as audited and determined by the
    Company's independent public accountants (the "Minimum Pretax Income")
    amounts to at least $17.5 million for the fiscal year ending December 31,
    1998;
 
        (ii) the Minimum Pretax Income amounts to at least $22.5 million for the
    fiscal year ending December 31, 1999;
 
       (iii) the Minimum Pretax Income amounts to at least $28.5 million for the
    fiscal year ending December 31, 2000;
 
        (iv) the Minimum Pretax Income amounts to at least $36.0 million for the
    fiscal year ending on December 31, 2001;
 
        (v) the Minimum Pretax Income amounts to at least $45.0 million for the
    fiscal year ending on December 31, 2002;
 
        (vi) the Minimum Pretax Income amounts to at least $56.0 million for the
    fiscal year ending on December 31, 2003;
 
       (vii) commencing on the date of this Prospectus and ending 18 months
    after the date of this Prospectus, the Bid Price (as defined herein) of the
    Company's Class A Common Stock averages in excess of $14.00 per share
    (subject to adjustment in the event of any reverse stock splits or other
    similar events) for 30 consecutive business days; or
 
      (viii) commencing 18 months after the date of this Prospectus and ending
    36 months after the date of this Prospectus, the Bid Price (as defined
    herein) of the Company's Class A Common Stock averages in excess of $18.50
    per share (subject to adjustment in the event of any reverse stock splits or
    other similar events) for 30 consecutive business days.
 
                                       51
<PAGE>
    (b) The 4,000,000 shares of outstanding Class E-2 Common Stock will be
converted into Class B Common Stock if, and only if, at least one of the
following conditions is met.
 
        (i) the Minimum Pretax Income amounts to at least $21.875 million for
    the fiscal year ending on December 31, 1998;
 
        (ii) the Minimum Pretax Income amounts to at least $28.125 million for
    the fiscal year ending on December 31, 1999;
 
       (iii) the Minimum Pretax Income amounts to at least $35.625 million for
    the fiscal year ending on December 31, 2000;
 
        (iv) the Minimum Pretax Income amounts to at least $45.0 million for the
    fiscal year ending on December 31, 2001
 
        (v) the Minimum Pretax Income amounts to at least $56.25 million for the
    fiscal year ending on December 31, 2002;
 
        (vi) the Minimum Pretax Income amounts to at least $69.5 million for the
    fiscal year ending on December 31, 2003;
 
       (vii) commencing on the date of this Prospectus and ending 18 months
    after the date of this Prospectus, the Bid Price (as defined herein) of the
    Company's Class A Common Stock averages in excess of $18.00 per share
    (subject to adjustment in the event of any reverse stock splits or other
    similar events) for 30 consecutive business days; or
 
      (viii) commencing 18 months after the date of this Prospectus and ending
    36 months after the date of this Prospectus, the Bid Price (as defined
    herein) of the Company's Class A Common Stock averages in excess of $23.00
    per share (subject to adjustment in the event of any reverse stock splits or
    other similar events) for 30 consecutive business days.
 
    The Minimum Pretax Income amounts set forth above (i) shall be calculated
exclusive of any extraordinary earnings or charge, including, but not limited
to, any charge to income resulting from conversion of the Performance Shares and
(ii) shall be increased proportionately, with certain limitations, in the event
additional shares of Common Stock or securities convertible into, exchangeable
for or exercisable into Common Stock are issued after completion of the
Offering. The bid price amounts set forth above are subject to adjustment in the
event of any stock splits, reverse stock splits or other similar events.
 
    If none of the applicable Minimum Pretax Income or bid price levels set
forth above have been met by March 31, 2004, the Performance Shares will be
redeemable by the Company at a price of $.01 per share. The Company expects that
the conversion of Performance Shares owned by officers, directors, employees and
consultants of the Company will be deemed compensatory and, accordingly, will
result in a substantial charge to reportable earnings equal to the fair market
value of such shares on the date of conversion. Such charge could substantially
increase the loss or reduce or eliminate the Company's net income for financial
reporting purposes for the period or periods during which such shares are, or
become probable of being, converted. Therefore, although the amount of
compensation expense recognized by the Company will not affect the Company's
cash flow, it may have a negative effect on the market price of the Company's
securities.
 
    The restrictions on the Class E-1 Common Stock and Class E-2 Common Stock
were required by the Underwriter as a condition to this Offering. The Minimum
Pretax Income and bid price levels set forth above were determined by
negotiation between the Company and the Underwriter and should not be construed
to imply or predict any future earnings by the Company or any increase in the
market price of its securities.
 
                                       52
<PAGE>
    Bid Price shall mean the closing bid price of the Class A Common Stock as
quoted on the Nasdaq SmallCap Market or as reported by the National Quotation
Bureau, Inc. or the closing sales price of the Class A Common Stock if it is
listed on the Nasdaq National Market or a national stock exchange.
 
    The "Minimum Pretax Income" amounts set forth above assume the conversion
into Class B Common Stock of all of the shares of Class E Common Stock and the
conversion into Class A Common Stock of any outstanding Class B Common Stock and
any other securities which are convertible into Class A or Class B Common Stock
solely upon surrender of such convertible securities without the payment of any
additional consideration, but shall be increased proportionally to reflect the
issuance of any other additional shares, including any shares that may be issued
upon the exercise of any warrants or options presently outstanding or hereafter
granted, provided, however, that, with respect to any shares of Class A Common
Stock issued upon exercise of warrants subject to a registration statement
covering shares of Class A Common Stock (the "Registration Statement") filed
with the Commission (provided such Registration Statement is filed on or before
September 30, 1996), so long as any portion of the net proceeds received by the
Company upon such exercise is not utilized by the Company, but such proceeds
(the "Invested Proceeds") are instead invested in short-term high interest
bearing securities or accounts or securities issued or guaranteed by the United
States government, then the adjustment to the Minimum Pretax Income amounts set
forth above with respect to that number of warrants which generated such
Invested Proceeds shall be equal to 8% per annum multiplied by such amount of
Invested Proceeds. The Minimum Pretax Income shall be calculated exclusive of
any extraordinary earnings or extraordinary charges including, but not limited
to, any charge to income resulting from the conversion of shares of Class E
Common Stock.
 
    CLASS B COMMON STOCK
 
    Each share of Class B Common Stock is convertible at any time commencing
thirteen months following the date of this Prospectus at the option of the
holder into one share of Class A Common Stock. Shares of Class B Common Stock
will also automatically convert into an equivalent number of fully paid and
non-assessable shares of Class A Common Stock after such period upon the sale or
transfer of such shares of Class B Common Stock (other than a transfer to
another holder of Class B Common Stock) by the original record holder thereof or
upon the death of the holder thereof unless and to the extent that such shares
are acquired by another holder of Class B Common Stock.
 
REDEEMABLE WARRANTS
 
    The following is a brief summary of certain provisions of the Warrants, but
such summary does not purport to be complete and is qualified in all respects by
reference to the actual text of the Warrant Agreement between the Company, the
Underwriter, and American Stock Transfer and Trust Company (the "Transfer and
Warrant Agent"). A copy of the Warrant Agreement has been filed as an exhibit to
the Registration Statement of which this Prospectus is a part.
 
    CLASS A WARRANTS
 
    The holder of each Class A Warrant is entitled, upon payment of the exercise
price of $6.50, to purchase one share of Class A Common Stock and one Class B
Warrant. Unless previously redeemed, the Class A Warrants are exercisable at any
time after their issuance until the fifth anniversary of the date of this
Prospectus, provided that at such time a current prospectus relating to the
Class A Common Stock and the Class B Warrants underlying the Class A Warrants is
in effect and the underlying Class A Common Stock and the Class B Warrants are
qualified for sale or exempt from qualification under applicable state
securities laws. The Class A Warrants included in the Units offered hereby are
immediately transferable separately from the Class A Common Stock and the Class
B Warrants issued with such Class A Warrants as part of the Units. The Class A
Warrants are subject to redemption, as described below.
 
                                       53
<PAGE>
    CLASS B WARRANTS
 
    The holder of each Class B Warrant is entitled, upon payment of the exercise
price of $8.75, to purchase one share of Class A Common Stock. Unless previously
redeemed, the Class B Warrants are exercisable at any time after their issuance
until the fifth anniversary of the date of this Prospectus, provided that at
such time a current prospectus relating to the underlying Class A Common Stock
is then in effect and the Class A Common Stock underlying the Warrants is
qualified for sale or exempt from qualification under applicable state
securities laws. The Class B Warrants included in the Units offered hereby are
transferable separately from the Class A Common Stock and Class A Warrants
issued with such Class B Warrants as part of the Units, and the Class B Warrants
underlying the Class A Warrants will be transferable separately from the Class A
Common Stock received upon exercise of the Class A Warrants. The Class B
Warrants are subject to redemption, as described below.
 
    REDEMPTION
 
    Commencing one year from the date of this Prospectus, the 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. The Class B Warrants are subject to redemption by the Company commencing
one year from the date of this Prospectus, 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 $15.00 per
share. Holders of Warrants will automatically forfeit their rights to purchase
the shares of Class A Common Stock and/or Class B Warrants issuable upon
exercise of such Warrants unless the Warrants are exercised before the close of
business on the business day immediately prior to the date set for redemption.
All of the outstanding Warrants of a class, except for those underlying the Unit
Purchase Option, must be redeemed if any of that class are redeemed. A notice of
redemption shall be mailed to each of the registered holders of the Warrants by
first class mail, postage prepaid, upon 30 days' notice before the date fixed
for redemption. The notice of redemption shall specify the redemption price, the
date fixed for redemption, the place where the Warrant certificates shall be
delivered and the redemption price to be paid, and that the right to exercise
the Warrants shall terminate at 5:00 p.m. (New York City time) on the business
day immediately preceding the date fixed for redemption.
 
    GENERAL
 
    The Warrants may be exercised upon surrender of the certificate or
certificates therefor on or prior to the expiration or the redemption date (as
explained above) at the offices of the Company's warrant agent (the "Warrant
Agent") with the subscription form on the reverse side of the certificate or
certificates completed and executed as indicated, accompanied by payment (in the
form of a certified or cashier's check payable to the order of the Company) of
the full exercise price for the number of Warrants being exercised.
 
    The Warrants contain provisions that protect the holders thereof against
dilution by adjustment of the exercise price per share and the number of shares
issuable upon exercise thereof upon the occurrence of certain events, including
issuances of Class A Common Stock (or securities convertible, exchangeable or
exercisable into Class A Common Stock) at less than market value, stock
dividends, stock splits, mergers, sale of substantially all of the Company's
assets, and for other extraordinary events; provided, however, that no such
adjustment shall be made upon, among other things, (i) the issuance or exercise
of options or other securities under the Company's Stock Option Plan or other
employee benefit plans or (ii) the sale or exercise of outstanding options or
warrants or the Warrants offered hereby.
 
                                       54
<PAGE>
    The Company is not required to issue fractional shares of Class A Common
Stock and in lieu thereof will make a cash payment based upon the current market
value of such fractional shares. The holder of the Warrants will not possess any
rights as a stockholder of the Company unless and until he or she exercises the
Warrants.
 
PREFERRED STOCK
 
    The Preferred Stock may be issued in series, and shares of each series will
have such rights, preferences, and privileges as are fixed by the Board of
Directors in the resolutions authorizing the issuance of that particular series.
In designating any series of Preferred Stock, the Board of Directors may,
without further action by the holders of Common Stock, fix the number of shares
constituting the series and fix the dividend rights, dividend rate, conversion
rights, voting rights (which may be greater or lesser than the voting rights of
the Common Stock), rights and terms of redemption (including any sinking fund
provisions), and the liquidation preferences of the series of Preferred Stock.
The holders of any series of Preferred Stock, when and if issued, are expected
to have priority claims to dividends and to any distributions upon liquidation
of the Company, and they may have other preferences over the holders of the
Common Stock.
 
    The Board of Directors may issue series of Preferred Stock without action by
the holders of the Common Stock. Accordingly, the issuance of Preferred Stock
may adversely affect the rights of the holders of the Common Stock. In addition,
the issuance of Preferred Stock may be used as an "anti-takeover" device without
further action on the part of the holders of the Common Stock. The issuance of
Preferred Stock may also dilute the voting power of the holders of Common Stock,
in that a series of Preferred Stock may be granted enhanced per share voting
rights and the right to vote on certain matters separately as a class, and may
render more difficult the removal of current management, even if such removal
may be in the stockholders' best interest. The Company has no current plans to
issue any Preferred Stock.
 
UNIT PURCHASE OPTION
 
    Upon the closing of the Offering, the Company has agreed to grant to the
Underwriter the Unit Purchase Option to purchase up to 500,000 Units. The Units
issuable upon exercise of the Unit Purchase Option will, when so issued, be
identical to the Units offered hereby. The Unit Purchase Option cannot be
transferred, sold, assigned or hypothecated for two years, except to any officer
of the Underwriter or members of the selling group or their officers. The Unit
Purchase Option is exercisable during the three-year period commencing two years
from the date of this Prospectus 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. See "Underwriting."
 
REGISTRATION RIGHTS
 
    The Company has granted certain demand and piggyback registration rights to
the holder of the Unit Purchase Option relating to their options and the
underlying securities. See "Underwriting."
 
TRANSFER AGENT AND WARRANT AGENT
 
    American Stock Transfer & Trust Company, New York, New York, will serve as
Transfer Agent for the shares of Common Stock and Warrant Agent for the
Warrants.
 
CERTAIN STATUTORY AND CHARTER PROVISIONS UNDER THE DELAWARE GENERAL CORPORATION
  LAW
 
    Section 203 of the Delaware General Corporation Law provides, in general,
that a stockholder acquiring more than 15% of the outstanding voting shares of a
publicly-held Delaware corporation subject to the statute (an "Interested
Stockholder") may not engage in certain "Business Combinations" with the
corporation for a period of three years subsequent to the date on which the
stockholder became an
 
                                       55
<PAGE>
Interested Stockholder unless (i) prior to such date the corporation's board of
directors approved either the Business Combination or the transaction in which
the stockholder became an Interested Stockholder or (ii) upon consummation of
the Business Combination, the Interested Stockholder owns 85% or more of the
outstanding voting stock of the corporation (excluding shares owned by directors
who are also officers of the corporation or shares held by employee stock option
plans that do not provide employees with the right to determine confidentially
whether shares held subject to the plan will be tendered in a tender or exchange
offer), or (iii) the Business Combination is approved by the corporation's board
of directors and authorized at an annual or special meeting of stockholders, and
not by written consent, by the affirmative vote of at least two-thirds of the
outstanding voting stock of the corporation not owned by the Interested
Stockholder.
 
    Section 203 defines the term "Business Combination" to encompass a wide
variety of transactions with or caused by an Interested Stockholder in which the
Interested Stockholder receives or could receive a benefit on other than a pro
rata basis with other stockholders, including mergers, certain asset sales,
certain issuances of additional shares to the Interested Stockholder or
transactions in which the Interested Stockholder receives certain other
benefits.
 
    These provisions could have the effect of delaying, deferring or preventing
a change of control of the Company. The Company's stockholders, by adopting an
amendment to the Certificate of Incorporation or Bylaws of the Company, may
elect not to be governed by Section 203, effective twelve months after adoption.
Neither the Certificate of Incorporation nor the Bylaws of the Company currently
excludes the Company from the restrictions imposed by Section 203.
 
    The Delaware General Corporation Law permits a corporation through its
Certificate of Incorporation to eliminate the personal liability of its
directors to the Corporation or its stockholders for monetary damages for breach
of fiduciary duty of loyalty and care as a director with certain exceptions. The
exceptions include a breach of the director's duty of loyalty, acts or omissions
not in good faith or which involve intentional misconduct or knowing violation
of law, and improper personal benefit. The Company's Certificate of
Incorporation exonerates its directors from monetary liability to the fullest
extent permitted by this statutory provision.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Upon completion of the Offering, the Company will have outstanding 5,000,000
shares of Class A Common Stock (5,750,000 shares of Class A Common Stock if the
Underwriter's over-allotment option is exercised in full) 2,000,000 shares of
Class B Common Stock, 4,000,000 shares of Class E-1 Common Stock and 4,000,000
shares of Class E-2 Common Stock. All of the shares of Class A Common Stock
offered hereby will be freely tradeable without restriction or further
registration under the Securities Act, except for any shares purchased by any
person who is or thereby becomes an "affiliate" of the Company, which shares
will be subject to the resale limitations contained in Rule 144 promulgated
under the Securities Act, as described below.
 
    All of the 10,000,000 shares of Class B Common Stock, Class E-1 Common
Stock, and Class E-2 Common Stock currently outstanding (and the shares of Class
A Common Stock or Class B Common Stock, as the case may be, into which they are
convertible) are "restricted securities" within the meaning of Rule 144 under
the Securities Act and, in general, may not be sold unless they are registered
under the Securities Act or sold pursuant to Rule 144 or another exemption from
registration. Pursuant to Rule 144, virtually all of these restricted shares
would be eligible for resale commencing 90 days following the date of this
Prospectus. However, 2,000,000 of the 10,000,000 outstanding shares are Class B
Common Stock and thus may not be sold until thirteen months after the date of
this Prospectus. In addition, the remaining 8,000,000 of the outstanding shares
are Class E Common Stock, which shares are not currently tradeable and are
subject to redemption by the Company for a nominal consideration if the Company
does not meet certain income or stock price levels, and are convertible into
Class B Common Stock if the Company does meet such levels. See "Description of
Securities."
 
    In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated), including a person who may be deemed to be an
"affiliate" of the Company as that term is defined under the Securities Act, is
entitled to sell, within any three month period, the number of shares
beneficially owned for at least two years that does not exceed the greater of
(i) one percent of the number of the then outstanding shares of Class A Common
Stock, or (ii) the average weekly trading volume of the Class A Common Stock
during the four calendar weeks preceding such sale. Sales under Rule 144 are
also subject to certain requirements as to manner of sale, notice and the
availability of current public information about the Company. Furthermore, a
person who is not deemed to have been an affiliate of the Company during the
ninety days preceding a sale by such person and who has beneficially owned such
shares for at least three years is entitled to sell such shares without regard
to the volume, manner of sale and notice requirements.
 
    In addition, Rule 701 under the Securities Act provides an exemption from
the registration requirements of the Act for offers and sales of securities
issued pursuant to certain compensatory benefit plans or written contracts of a
company not subject to the reporting requirements of Section 13 or 15(d) of the
Exchange Act. Securities issued pursuant to Rule 701 are defined as restricted
securities for purposes of Rule 144. However, 90 days after the issuer becomes
subject to the reporting provisions of the Exchange Act, the Rule 144 resale
restrictions, except for the broker's transaction requirements, are inapplicable
for nonaffiliates. Affiliates are subject to all Rule 144 restrictions after
this 90-day period, but without the Rule 144 holding period requirement.
 
    Holders of the Class A Warrants included in the Units offered hereby
(assuming no exercise of the Underwriter's over-allotment option) will be
entitled to purchase an aggregate of 5,000,000 shares of Class A Common Stock
upon exercise of the Class A Warrants and holders of the Class B Warrants
offered hereby and underlying the Class A Warrants offered hereby will be
entitled to purchase an aggregate of 10,000,000 additional shares of Class A
Common Stock upon exercise of the Class B Warrants, in each case at any time
during the five-year period following the date of this Prospectus, provided that
the Company satisfies certain securities registration requirements with respect
to the securities underlying the Warrants.
 
                                       57
<PAGE>
    Up to 2,000,000 additional shares of Class A Common Stock may be purchased
by the Underwriter through the exercise of the Unit Purchase Option and the
Class A Warrants and Class B Warrants contained in and underlying the Unit
Purchase Option. Any and all of such shares of Class A Common Stock will be
tradeable without restriction, provided that the Company satisfies certain
securities registration requirements in accordance with the terms of the Unit
Purchase Option. The Underwriter also has demand and "piggyback" registration
rights with respect to the securities underlying the Unit Purchase Option. See
"Underwriting."
 
    The Company has also registered on behalf of the Selling Securityholders an
aggregate of 3,500,000 Selling Securityholders' Class A Warrants and the
securities underlying such Class A Warrants. The Selling Securityholders have
agreed not to sell their Selling Securityholder Class A Warrants or the
securities issuable on exercise thereof except pursuant to the restrictions set
forth below:

    The Selling Securityholders have also agreed with the Company not to
exercise the Selling Securityholders' Class A Warrants for a period of one year
following the closing of the Offering; provided, however, that purchasers of
such Selling Securityholders' Class A Warrants are not subject to this
restriction on exercise.
 
    The Company has adopted a Stock Option Plan and reserved 500,000 shares of
Class A Common Stock for issuance under the Plan. As of the date of this
Prospectus, the Company has granted options under the Plan to purchase 110,000
shares of Class A Common Stock. Such options vest in equal annual installments
over five years. See "Management--Stock Option Plan."
 
    Prior to the Offering, no public market for the Company's securities has
existed. Following the Offering, no predictions can be made of the effect, if
any, of future public sales of restricted shares or the availability of
restricted shares for sale in the public market. Moreover, the Company cannot
predict the number of shares of Class A Common Stock that may be sold in the
future pursuant to Rule 144 or Rule 701 because such sales will depend on, among
other factors, the market price of the Class A Common Stock and the individual
circumstances of the holders thereof. The availability for sale of substantial
amounts of Class A Common Stock acquired through the exercise of the Class A
Warrants and Class B Warrants, under Rule 144 or Rule 701, other options or the
Unit Purchase Option could adversely affect prevailing market prices for the
Company's securities.

                                  UNDERWRITING
 
    D.H. Blair Investment Banking Corp., the Underwriter, has agreed, subject to
the terms and conditions of the Underwriting Agreement, to purchase the
5,000,000 Units offered hereby from the Company on a "firm commitment" basis, if
any are purchased. It is expected that Blair & Co. will distribute as a selling
group member substantially all of the Units offered hereby. Blair & Co. is owned
by a corporation that is substantially owned by family members of J. Morton
Davis. Mr. Davis is the sole stockholder of the Underwriter.
 
    The Underwriter has advised the Company that it proposes to offer the Units
to the public at the public offering price set forth on the cover page of this
Prospectus. The Underwriter may allow to selected dealers who are members of the
National Association of Securities Dealers, Inc. (the "NASD") concessions not in
excess of $.      per Unit, of which not in excess of $.      per Unit may be
reallowed to other dealers who are members of the NASD. After commencement of
the offering, the public offering price, concession and the reallowance may be
changed by the Underwriter.
 
    The Company has agreed to indemnify the Underwriter against certain
liabilities, including liabilities under the Securities Act. The Company has
also agreed to pay to the Underwriter a nonaccountable expense allowance of 3%
of the gross proceeds derived from the sale of the Units offered hereby,
including any Units purchased pursuant to the Underwriter's over-allotment
option, $40,000 of which has been paid as of the date of this Prospectus.
 
    The Underwriter has informed the Company that it does not expect sales to
any discretionary accounts to exceed 5% of the Offering.
 
    The Company has granted to the Underwriter an option, exercisable during the
30-day period commencing on the date of this Prospectus, to purchase from the
Company at the public offering price, less underwriting discounts and
commissions, up to 750,000 additional Units for the purpose of covering
over-allotments, if any.
 
    The Company has agreed to sell to the Underwriter and its designees, for
nominal consideration, the Unit Purchase Option to purchase up to 500,000 Units
substantially identical to the Units being offered hereby, except that the
Warrants included therein are subject to redemption by the Company at any time
after the Unit Purchase Option has been exercised and the underlying Warrants
are outstanding. The Unit Purchase Option will be exercisable during the
three-year period commencing two years from the date of this Prospectus at an
exercise price of $6.50 per Unit, subject to adjustment in certain events to
protect against dilution, and is not transferable for a period of two years from
the date of this Prospectus except to officers of the Underwriter or to members
of the Underwriter's selling group. The Company has agreed to register the
securities issuable upon exercise thereof under the Securities Act on two
separate occasions (the first at the Company's expense and the second at the
expense of the holders of the Unit Purchase Option) during the five-year period
commencing one year from the date of this Prospectus. The Unit Purchase Option
includes a provision permitting the holder to elect a cashless exercise of the
Option. The Company has also granted certain piggyback rights to holders of the
Unit Purchase Option.
 
    The Underwriter has the right to designate one director for nomination to
the Company's Board of Directors for a period of five years from the completion
of the Offering. Such designee may be a director, officer, partner, employee or
affiliate of the Underwriter.
 
    During the five-year period from the closing of the Offering, in the event
the Underwriter originates any transaction, including mergers, acquisitions and
joint ventures, to which the Company is a party, the Underwriter will be
entitled to receive a finder's fee in consideration for origination of such
transaction. The fee is based on a percentage of the consideration paid in the
transaction, ranging from 7% of the first $1,000,000 to 2.5% of any
consideration in excess of $9,000,000.
 
                                       59
<PAGE>
    The Underwriter acted as placement agent in connection with the Bridge
Financing in August 1996 and, in connection therewith, received a placement
agent fee of $560,000 and a non-accountable expense allowance of $210,000.
 
    The Company has agreed not to solicit Warrant exercises other than through
the Underwriter, unless the Underwriter declines to make such solicitation. Upon
any exercise of the Class A or Class B Warrants after one year from the date of
this Prospectus, the Company will pay the Underwriter a fee of 5% of the
aggregate exercise price for Warrant exercises solicited by the Underwriter or
its representatives or agents, if (i) the market price of the Company's Class A
Common Stock on the date the Warrant is exercised is greater than the then
exercise price of the Warrants; (ii) the exercise of the Warrant was solicited
in writing by a member of the NASD; (iii) the Warrant is not held in a
discretionary account; (iv) disclosure of compensation arrangements was made
both at the time of the offering and at the time of exercise of the Warrants;
and (v) the solicitation of exercise of the Warrant was not in violation of Rule
10b-6 promulgated under the Exchange Act.
 
    Rule 10b-6 may prohibit Blair & Co. from engaging in any market making
activities with regard to the Company's securities for the period from two to
nine business days (or such other applicable period as Rule l0b-6 may provide)
prior to any solicitation by the Underwriter of the exercise of Warrants until
the later of the termination of such solicitation activity or the termination
(by waiver or otherwise) of any right that the Underwriter may have to receive a
fee for the exercise of Warrants following such solicitation. As a result, Blair
& Co. may be unable to provide a market for the Company's securities during
certain periods while the Warrants are exercisable.
 
    The Commission is conducting an investigation concerning various business
activities of the Underwriter and Blair & Co. The investigation appears to be
broad in scope, involving numerous aspects of the Underwriter's and Blair & Co's
compliance with the federal securities laws and compliance with the federal
securities laws by issuers whose securities were underwritten by the Underwriter
or Blair & Co., or in which the Underwriter or Blair & Co. made over-the-counter
markets, persons associated with the Underwriter or Blair & Co., such issuers
and other persons. The Company has been advised by the Underwriter that the
investigation has been ongoing since at least 1989 and that it is cooperating
with the investigation. The Underwriter cannot predict whether this
investigation will ever result in any type of formal enforcement action against
the Underwriter or Blair & Co. or, if so, whether any such action might have an
adverse effect on the Underwriter or the securities offered hereby. The Company
has been advised that Blair & Co. will make a market in the securities following
the Offering. An unfavorable resolution of the Commission's investigation could
have the effect of limiting such firm's ability to make a market in the
Company's securities, which could adversely affect the liquidity or price of
such securities.
 
    Prior to the Offering, there has been no market for any of the securities
offered hereby. Accordingly, the initial public offering price of the Units and
the exercise prices and other terms of the Warrants have been determined by
negotiations between the Company and the Underwriter and are not necessarily
related to the Company's assets, net worth or other established criteria of
value. Factors considered in determining such prices and terms, in addition to
prevailing market conditions, include the history of, and prospects for, the
industry in which the Company competes, the Company's management, the Company's
financial condition, the Company's capital structure and such other factors as
were deemed relevant.
 
                                 LEGAL MATTERS
 
    The validity of the securities offered hereby will be passed upon for the
Company by Luce, Forward, Hamilton & Scripps LLP, San Diego, California. The
statements herein relating to federal aviation regulatory matters will be passed
upon by Boros & Garofalo, P.C., Washington, D.C. Certain legal matters will be
passed upon for the Underwriter by Bachner, Tally, Polevoy & Misher LLP, New
York, New York.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and
 
  Stockholders of Advanced Aerodynamics
  & Structures, Inc.
  (A Development Stage Enterprise)
 
    In our opinion, the accompanying balance sheet and the related statements of
operations, of stockholders' deficit, and of cash flows present fairly, in all
material respects, the financial position of Advanced Aerodynamics & Structures,
Inc. (a Development Stage Enterprise) at December 31, 1995, and the results of
its operations and its cash flows for the years ended December 31, 1994 and 1995
and for the period from January 26, 1990 (inception) to December 31, 1995, in
conformity with generally accepted accounting principles. 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 of these statements in accordance with
generally accepted auditing standards which 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,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.
 
    The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 1 to the
financial statements, the Company has suffered recurring losses during the
development stage and has a working capital deficit and a stockholders' deficit
that raise substantial doubt about its ability to continue as a going concern.
Management's plans in regard to these matters are also described in Note 1. The
financial statements do not include any adjustments that might result from the
outcome of this uncertainty.

                         NOTES TO FINANCIAL STATEMENTS
 
1. THE COMPANY
 
    Advanced Aerodynamics & Structures, Inc. (the "Company" or "AASI") was
incorporated in California on January 26, 1990. The 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; the
Company's ability to manufacture aircraft to its present design is dependent on
its having access to such engines.
 
    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. The Company's
aforementioned common and preferred shares were converted into approximately
619,588, 1,239,177 and 1,239,177 shares, respectively, upon reincorporation of
the Company into Class B, Class E-1 and Class E-2 Common Stock as part of the
July 1996 recapitalization described below.
 
    In July 1996, the Company reincorporated by merging with a newly formed
corporation in Delaware (the "reincorporation"). In connection with the
reincorporation, the Company (i) increased the authorized capital of the Company
to 63,000,000 shares of $.0001 par value common stock, of which 45,000,000 are
designated Class A Common Stock, 10,000,000 are designated Class B Common Stock,
4,000,000 are designated Class E-1 Common Stock and 4,000,000 are designated
Class E-2 Common Stock (Note 7) and (ii) authorized 5,000,000 shares of $.0001
par value preferred stock. All issued and outstanding shares of common and
preferred stock at the time of the reincorporation were exchanged into
approximately .0557 shares of Class B common stock, approximately .1115 shares
of Class E-1 common stock and approximately .1115 shares of Class E-2 common
stock (the "recapitalization"). All share and per share data have been
retroactively restated to reflect the recapitalization.

stockholders' deficit of $12,280,000 at December 31, 1995. The Company expects
to continue to incur losses for the foreseeable future due to the significant
costs anticipated to be incurred with the development, certification,
manufacture and marketing of its product. In August 1996, the Company completed
a private placement of bridge financing (Note 8). Success of future operations
is dependent upon, among other things, the Company's ability to obtain necessary
additional capital and appropriate government certification for the commercial
production of its aircraft. The Company intends to actively pursue the
contemplated initial public offering (Note 8) to develop, manufacture and market
its product to achieve commercial viability. In the event the proposed public
offering is not consummated, the Company intends to limit expenditures and seek
alternative sources of financing. The net proceeds of the offering, if
consummated, will be used to amend its Federal Aviation Administration ("FAA")
Type Certificate for technical revisions to its product, establish a production
line and obtain a FAA Production Certificate for its product, repay borrowings
under a bridge loan (Note 8), expand the Company's sales and marketing efforts,
establish a new manufacturing facility, and acquire production materials and
additional tooling and equipment.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
1. THE COMPANY (CONTINUED)
    The Company is subject to all of the risks inherent in a new business
enterprise and the likelihood of the success of the Company must be considered
in light of the difficulties and delays frequently encountered in connection
with a new business. These matters raise substantial doubt about the Company's
ability to continue as a going concern. The financial statements do not include
any adjustments that might result from the outcome of this uncertainty.
 
    NET LOSS PER SHARE
 
    The Company's net loss per share was computed based on the weighted average
number of shares of common stock outstanding during the years ended December 31,
1994 and 1995 and the six months ended June 30, 1995 and 1996 and excludes all
outstanding shares of Class E-1 and Class E-2 Common Stock because the
conditions for the lapse of restrictions on such shares have not been satisfied
(Note 7).
 
    Pursuant to Securities and Exchange Commission Staff Accounting Bulletin No.
83, stock options and warrants granted and common shares issued since July 1,
1995 other than Class E-1 and Class E-2 Common Stock have been included as
outstanding in net loss per share computations for all periods presented using
the treasury stock method and the expected public offering price per share.
 
    UNAUDITED INTERIM INFORMATION
 
    The information presented as of June 30, 1996, and for the six months ended
June 30, 1995 and 1996, has not been audited. In the opinion of management, the
unaudited interim financial statements include all adjustments, consisting only
of normal recurring adjustments, necessary to present fairly the results for the
interim periods presented. The information disclosed in the notes to the
financial statements as of such date and for such periods are also unaudited.
 
2. 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.
 
    PROPERTY AND EQUIPMENT
 
    Property and equipment are stated at cost and are depreciated using the
straight-line method over their estimated useful lives of five to ten years.
Leasehold improvements are amortized over the shorter of their estimated useful
lives or the term of the lease.
 
    OTHER INCOME
 
    Other income consists primarily of sales of aircraft engines used for
testing.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    PREPAID EXPENSES AND OTHER CURRENT ASSETS
 
    Prepaid expenses and other current assets consist primarily of deposits for
aircraft engines.
 
    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, all or some portion
of, such deferred tax assets will not be realized.
 
    USE OF 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.
 
    FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The Company's financial instruments consist primarily of a certificate of
deposit, prepaid expenses and other current assets, accounts payable, accrued
and other current liabilities, and short-term loans. The carrying value of these
financial instruments approximates fair value due to their short-term nature.
 
    NEW ACCOUNTING PRONOUNCEMENTS
 
    The Financial Accounting Standards Board ("FASB") issued Statement No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
Be Disposed Of" ("SFAS No. 121"). SFAS No. 121 was adopted by the Company
effective January 1, 1996. The adoption of SFAS No. 121 did not have a material
impact on the Company's financial position, results of operations or liquidity.
 
    The FASB issued Statement No. 123, "Accounting for Stock-Based Compensation"
("SFAS No. 123"). SFAS No. 123 establishes an alternative method of accounting
for stock-based compensation plans and must be adopted in the Company's 1996
financial statements. The Company intends to adopt only the disclosure
provisions for stock compensation and does not expect that the adoption of SFAS
No. 123 will have a material impact on the Company's financial position, results
of operations or liquidity.

4. INCOME TAXES
 
    The temporary differences and carryforwards which give rise to the Company's
net deferred tax assets at December 31, 1995 of $7,675,000 were subject to a
full valuation allowance because their realization is not likely. The primary
components of the temporary differences consisted of net operating loss and
research and development credits carryforwards.
 
    At December 31, 1995, the Company had Federal tax net operating loss ("NOL")
carryforwards of approximately $17 million which will, if unused, expire in
varying amounts in years 2005 through 2010. The Company also had California
franchise tax NOL carryforwards of approximately $3 million which will, if
unused, expire in various amounts in years 1996 through 2000.
 
    At December 31, 1995, the Company had Federal and California research and
development ("R&D") credit carryforwards of approximately $1,169,000 and
$468,000, respectively. The Federal R&D credit carryforwards will expire in
years 2005 through 2010. The California R&D credit carryforwards can be carried
forward indefinitely.
 
    Utilization of the net operating loss and tax credit carryforwards may be
subject to an annual limitation if a change in the Company's ownership should
occur as defined by Section 382 of the Internal Revenue Code.
 
    As a result of the Company's operating losses, no income tax provision has
been recorded.
 
5. DEBT AND RELATED PARTY TRANSACTIONS
 
    As of December 31, 1995, the loan from SIDA Corporation (Note 6) of $110,000
and the loans from non-affiliated individuals aggregating $565,000 are payable
on demand and bear interest at 12% per annum. One of these individuals
subsequently became a director of the Company in June 1996.
 
    The loan from officer amounting to $160,000 at December 31, 1995 increased
to $336,000 in April 1996 which was subsequently converted in May 1996 to
187,118 shares of Class B Common Stock and 374,236 shares each of Class E-1 and
Class E-2 Common Stock. An additional $191,000 was advanced subsequent to such
conversion and was outstanding at June 30, 1996. Interest payable accrued at 12%
per annum and amounted to $22,000 at June 30, 1996.
 
    The note payable to bank matures in October 1996, bears interest of prime
rate plus 1.5% (10% per annum at December 31, 1995) and is guaranteed by the
United States Small Business Administration, the

California Export Finance Office and the Company's President, and secured by
substantially all of the Company's assets.
 
    On December 23, 1993, the Company entered into an agreement with a
stockholder to convert the advances from such stockholder aggregating
$10,478,000 at that date to 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 to equity. In 1994 the stockholder provided additional advances
aggregating $250,000, which were converted to 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. Imputed interest on all advances, based on prevailing market rates, of
$23,000 in 1995, $11,000 in 1994 and $799,000 for the period from January 26,
1990 (inception) to December 31, 1995 was charged to expense and credited to
additional paid-in capital.
 
6. COMMITMENTS, CONTINGENCIES AND EMPLOYMENT AGREEMENTS
 
    In January 1990, the Company entered into a five-year management services
agreement (the "1990 Agreement") with SIDA Corporation, the stockholders of
which are also minority stockholders of the Company. During the period from
January 26, 1990 (inception) to December 31, 1995, the Company incurred $700,000
of service fees ($140,000 and $12,000 in 1994 and 1995, respectively) pursuant
to this agreement. As of December 31, 1995, the unpaid service fee of $259,000
and interest of $31,000, accrued at 12% per annum, are included in accrued
liabilities and interest payable, respectively, in the accompanying balance
sheet.
 
    In January 1995, the 1990 Agreement expired and was replaced by a new
management services agreement (the "1995 Agreement") entered into with the
Company's President on December 29, 1994 for an original term of ten years. The
1995 Agreement provides for an annual base compensation of $350,000 to be paid
to the Company's President, a $250,000 signing incentive payable in shares of
common stock and additional common stock to be earned for services performed.
Pursuant to the 1995 Agreement, the unpaid base compensation of $323,000 and
interest of $39,000, accrued at 12% per annum, are included in accrued
liabilities and interest payable, respectively, in the accompanying balance
sheet at December 31, 1995. The liability for signing incentive of $250,000 and
additional compensation for services performed of $367,000 that was ultimately
paid in the form of shares of common stock was included in accrued liabilities
at December 31, 1995. Unpaid base compensation of $300,000 was subsequently
converted to shares of Class B, Class E-1 and Class E-2 Common Stock as
discussed below.
 
    In May 1996, the 1995 Agreement was terminated and renegotiated (see below).
The following shares of Class B, Class E-1 and Class E-2 Common Stock were
issued to the Company's President pursuant to the terms of the 1995 Agreement
and in consideration of the termination thereof:

6. COMMITMENTS, CONTINGENCIES AND EMPLOYMENT AGREEMENTS (CONTINUED)
    Stock compensation cost of $250,000, $367,000 and $559,000 in 1994, 1995 and
the six months ended June 30, 1996, respectively, was charged to expense based
on the fair value of the stock awarded by reference to an independent appraisal.
 
    In May 1996, the Company entered into an employment agreement with the
Company's President, which replaced the terminated 1995 Agreement. This
employment agreement 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.
 
    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 the six months ended June 30, 1996 based on the fair value of the stock
awarded by reference to an independent appraisal.
 
    The Company leases its office and warehouse facility for approximately
$12,000 per month on a month-to-month basis.
 
    In the ordinary course of business, the Company is generally subject to
claims, complaints, and legal actions. The litigation process is inherently
uncertain and it is possible that the resolution of such matters might have a
material adverse effect upon the financial position of the Company. However, in
the opinion of management, such matters are not expected to have a material
adverse effect on the Company's financial position, results of operations or
liquidity.
 
7. STOCKHOLDERS' EQUITY
 
    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, (ii) Class B Common
Stock cannot be transferred or sold for thirteen months following the effective
date of the 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.
 
    CLASS E-1 AND E-2 COMMON STOCK
 
    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, 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 exceeds $17.5 million in 1998, $22.5
million in 1999, $28.5 million in 2000, $36.0 million in 2001, $45.0 million in
2002 and $56.0 million in 2003. Class E-2 Common Stock shares may be converted
if pretax income exceeds $21.875 million in 1998, $28.125 million in 1999,
$35.625 million in 2000, $45.0 million in 2001, $56.25 million in 2002 or $69.5
million in 2003. With respect to market price levels, the

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
7. STOCKHOLDERS' EQUITY (CONTINUED)
Class E-1 Common Stock shares may be converted if, commencing at the effective
date of the public offering (see Note 8) and ending 18 months thereafter, the
bid price of the Company's Class A Common Stock averages in excess of $14.00 per
share for 30 consecutive business days, or commencing 18 months after the
effective date and ending 36 months after the effective date, the bid price
averages $18.50 per share for 30 consecutive business days. Class E-2 Common
Stock shares may be converted if commencing at the effective date of the public
offering and ending 18 months thereafter, the bid price of the Company's Class A
Common Stock averages in excess of $18.00 per share for 30 consecutive business
days or commencing 18 months after such date and ending 36 months after such
date, the bid price 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.
 
    STOCK OPTION PLAN
 
    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. Under the Plan, the Company may grant options with respect to
500,000 shares of the Class A Common Stock. The options are to be granted at not
less than fair market value, vest immediately and may be exercised for a period
of one to ten years as determined by the Board of Directors. In September 1996,
options to purchase 110,000 shares of Class A Common Stock were granted at an
exercise price of $5 per share.
 
8. PROPOSED PUBLIC OFFERING
 
    On May 13, 1996, the Company entered into a letter of intent, as amended on
July 23, 1996, with an underwriter (the "Underwriter") whereby the Underwriter
has agreed in principle to act as an underwriter in an initial public offering
of units (the "Units"). Each Unit will be comprised of one share of the
Company's Class A Common Stock, one Class A Warrant and one Class B Warrant.
Upon exercise, 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.
 
    On August 30, 1996, the Company completed a private placement of an
aggregate of $7,000,000 principal amount of notes (the "Bridge Notes") and
3,500,000 warrants (the "Bridge Warrants") in which it received net proceeds of
approximately $6,195,000 (after expenses of issuance). The Bridge Notes are
payable, together with cash interest at the rate of 10% per annum, on the
earlier of one year from the issuance of the Bridge Notes or the closing of the
proposed public offering discussed above. Each Bridge Warrant will be
exercisable for a period commencing one year from the date of issuance and
expiring approximately two years thereafter, and entitles the holder thereof to
purchase one share of Class A Common Stock at an exercise price of $3.00 per
share if the Company does not consummate the proposed public offering. In the
event the Company completes the proposed offering and such offering includes
warrants or Class A Warrants, each Bridge Warrant will automatically convert on
the closing date of the public offering into one warrant or Class A Warrant (a
"Public Warrant") which is identical in all respects

to the Class A Warrant sold in the public offering, except that purchasers of
the Bridge Notes acquiring the Bridge Warrants have agreed (i) not to exercise
the Public Warrants for a period of one year from the closing date of the public
offering and (ii) not to sell publicly the Public Warrants except as provided in
certain lock-up provisions which expire between 90 and 270 days after the
closing date of the public offering. The fair value of the Bridge Warrants,
together with the cost of issuance (approximately $805,000), will be treated as
additional interest expense over the term of the Bridge Notes.

PROSPECTUS
                    ADVANCED AERODYNAMICS & STRUCTURES, INC.
 
                     3,500,000 Redeemable Class A Warrants
                   3,500,000 Redeemable Class B Warrants and
                    7,000,000 Shares of Class A Common Stock
 
    This Prospectus relates to 3,500,000 redeemable Class A Warrants (the
"Selling Securityholders' Warrants" or the "Class A Warrants") of Advanced
Aerodynamics & Structures, Inc., a Delaware corporation (the "Company"), issued
to certain investors upon the conversion of warrants issued to such investors
(the "Selling Securityholders") in a private placement by the Company completed
in August 1996 (the "Bridge Financing"), the 3,500,000 redeemable Class B
Warrants (the "Class B Warrants") issuable upon exercise of the Class A
Warrants, and the 7,000,000 shares of Class A Common Stock, $.0001 par value, of
the Company (the "Class A Common Stock") underlying the Class A Warrants and
Class B Warrants. See "Selling Securityholders and Plan of Distribution." Each
Class A Warrant entitles the holder to purchase one share of Class A Common
Stock and one Class B Warrant at an exercise price of $6.50, subject to
adjustment, until the fifth anniversary of the date of this Prospectus. Each
Class B Warrant entitles the holder to purchase one share of Class A Common
Stock at an exercise price of $8.75, subject to adjustment, until the fifth
anniversary of the date of this Prospectus. The Class A Warrants and the Class B
Warrants are subject to redemption, commencing one year from the date of this
Prospectus, by the Company at $.05 per Warrant on 30 days' written notice if the
closing bid price of the Class A Common Stock for 30 consecutive trading days
ending within 15 days of the notice of redemption of the Warrants averages in
excess of $12.00 per share with respect to the Class A Warrants and $15.00 per
share with respect to the Class B Warrants (subject to adjustment in each case).
See "Description of Securities."
 
    The Selling Securityholders have agreed not to exercise the Selling
Securityholders' Warrants for a period of one year from the closing of the
Offering and not to sell the Selling Securityholders' Warrants for a period of
90 days after the closing of the Offering and to sell only certain specified
percentages of such warrants during the period from 91 to 270 days after such
closing. However, purchasers of such warrants in permitted sales will be
entitled to exercise such warrants immediately.
 
    The securities offered by this Prospectus may be sold from time to time by
the Selling Securityholders, or by their transferees. The distribution of the
securities offered hereby may be effected in one or more transactions that may
take place in the over-the-counter market, including ordinary brokers'
transactions, privately negotiated transactions or through sales to one or more
dealers for resale of such securities as principals, at market prices prevailing
at the time of sale, at prices related to such prevailing market prices or at
negotiated prices. Usual and customary or specifically negotiated brokerage fees
or commissions may be paid by the Selling Securityholders.
 
    The Selling Securityholders and intermediaries through whom such securities
are sold may be deemed "underwriters" within the meaning of the Securities Act
of 1933, as amended (the "Securities Act"), with respect to the securities
offered, and any profits realized or commission received may be deemed
underwriting compensation. The Company has agreed to indemnify the Selling
Securityholders against certain liabilities, including liabilities under the
Securities Act.
 
    The Company will not receive any of the proceeds from the sale of securities
by the Selling Securityholders. In the event the Warrants are fully exercised,
the Company will receive gross proceeds of $53,375,000. See "Selling
Securityholders and Plan of Distribution."
 
    On September 19, 1996, the Company filed a registration statement under the
Securities Act with the Securities and Exchange Commission (the "Commission")
relating to a public offering by the Company (the "Offering") of 5,000,000
Units, each Unit consisting of one share of Class A Common Stock, one Class A
Warrant and one Class B Warrant. The Company will receive approximately
$22,047,000 in net proceeds from the sale of the Units (assuming no exercise of
the Underwriter's over-allotment option) after payment of underwriting discounts
and commissions and estimated expenses of the Offering.

(1) Does not include shares of Class A Common Stock and Class B Warrants
    issuable upon exercise of the Class A Warrants and the shares of Class A
    Common Stock issuable upon exercise of the Class B Warrants. The Selling
    Securityholders have agreed not to exercise the Class A Warrants offered
    hereby for a period of one year after the closing of the Offering.
 
                              PLAN OF DISTRIBUTION
 
    The sale of the securities by the Selling Securityholders may be effected
from time to time in transactions (which may include block transactions by or
for the account of the Selling Securityholders) in the over-the-counter market
or in negotiated transactions, a combination of such methods of sale or
otherwise. Sales may be made at fixed prices which may be changed, at market
prices prevailing at the time of sale, or at negotiated prices.
 
    Selling Securityholders may effect such transactions by selling their
securities directly to purchasers, through broker-dealers acting as agents for
the Selling Securityholders or to broker-dealers who may purchase shares as
principals and thereafter sell the securities from time to time in the
over-the-counter market, in negotiated transactions or otherwise. Such
broker-dealers, if any, may receive compensation in the form of discounts,
concessions or commissions from the Selling Securityholders or the purchasers
for whom such broker-dealers may act as agents or to whom they may sell as
principals or otherwise (which compensation as to a particular broker-dealer may
exceed customary commissions).
 
                                      A-4
<PAGE>
    Each Selling Securityholder has agreed (i) not to sell, transfer or
otherwise dispose of publicly the Selling Securityholder Warrants except after
the time periods and in the percentage amounts set forth below, on a cumulative
basis, and (ii) not to exercise the Selling Securityholder Warrants for a period
of one year after the closing of the Offering. Purchasers of the Selling
Securityholder Warrants will not be subject to such restrictions.

    Under applicable rules and regulations under the Exchange Act, any person
engaged in the distribution of the Selling Securityholders' Warrants may not
simultaneously engage in market making activities with respect to any securities
of the Company for a period of at least two (and possibly nine) business days
prior to the commencement of such distribution. Accordingly, in the event the
Underwriter of the Company's initial public offering or D.H. Blair & Co., Inc.
("Blair & Co.") is engaged in a distribution of the Selling Securityholders'
Warrants, neither of such firms will be able to make a market in the Company's
securities during the applicable restrictive period. However, neither the
Underwriter nor Blair & Co. has agreed to, nor is either of them obligated to,
act as a broker-dealer in the sale of the Selling Securityholders' Warrants, and
the Selling Securityholders may be required, and in the event Blair & Co. is a
market maker, will likely be required, to sell such securities through another
broker-dealer. In addition, each Selling Securityholder desiring to sell
Warrants will be subject to the applicable provisions of the Exchange Act and
the rules and regulations thereunder, including without limitation, Rules 10b-6
and 10b-7, which provisions may limit the timing of the purchases and sales of
shares of the Company's securities by such Selling Securityholders.
 
    The Selling Securityholders and broker-dealers, if any, acting in connection
with such sales may be deemed to be "underwriters" within the meaning of Section
2(11) of the Securities Act and any commission received by them and any profit
on the resale of the securities by them might be deemed to be underwriting
discounts and commissions under the Securities Act.
 
                           CONCURRENT PUBLIC OFFERING
 
    On the date of this Prospectus, a Registration Statement under the
Securities Act was declared effective with respect to an underwritten offering
of 5,000,000 Units by the Company (5,750,000 Units if the Underwriter's
over-allotment option is exercised in full), each Unit consisting of one share
of Class A Common Stock, one Class A Warrant and one Class B Warrant.

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 24.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    Reference is made to Section 145 of the General Corporation Law of the State
of Delaware. As permitted by Delaware law, the Company's Certificate of
Incorporation contains an article limiting the personal liability of directors.
The Certificate of Incorporation provides that a director of the Company shall
not be personally liable for any damages from any breach of fiduciary duty as a
director, except for liability based on a judgment or other final adjudication
adverse to him establishing that his acts or omissions were committed in bad
faith or were the result of active or deliberate dishonesty and were material to
the cause of action so adjudicated, or that he personally gained a financial
profit or other advantage to which he was not legally entitled. The Company's
Certificate of Incorporation and Bylaws also provide for indemnification of all
officers and directors of the Company to the fullest extent permitted by law.
 
    The Company has entered into Indemnification Agreements ("Indemnification
Agreements") with each of Dr. Carl Chen, Gene Comfort, Sandra Andre, C.M. Cheng
and Steve Gorlin (collectively, the "Indemnitees"). The Indemnification
Agreements permit the Company to indemnify the Indemnitees for liabilities and
expenses arising from certain actions taken by the Indemnitees for or on behalf
of the Company and require indemnification in certain circumstances.
 
ITEM 25.  OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION
 
    The following table sets forth the estimated expenses to be incurred in
connection with the offering, other than underwriting discounts, commissions and

ITEM 26.  RECENT SALES OF UNREGISTERED SECURITIES
 
    The following discussion gives retroactive effect to the Recapitalization
effected by the Registrant in July 1996. The Registrant has sold and issued the
following securities during the past three years.
 
    In September 1996, the Registrant issued options to purchase 25,000 shares
of Class A Common Stock to each of Gene Comfort, C.M. Cheng, William Leeds and
Steve Gorlin and options to purchase 5,000 shares of Class A Common Stock to
each of Chom Kruesopon and Sandra Andre under the Registrant's 1996 Stock Option
Plan. These options are exercisable at a price of $5.00 per share and vest in
equal annual installments over five years. Messrs. Comfort, Cheng and Gorlin are
members of the Registrant's
 
                                      II-1
<PAGE>
Board of Directors; Mr. Leeds is currently a consultant to the Registrant and
has agreed to become a Senior Vice President of the Company following the
closing of the Offering; Ms. Kruesopon is an employee of the Registrant; Ms.
Andre is the Registrant's Chief Financial Officer; and Mr. Comfort is the
Registrant's Executive Vice President and Secretary. The securities were issued
in reliance on Section 4(2) of the Securities Act, and no commissions or
discounts were paid.
 
    In August 1996, in connection with the Bridge Financing, the Registrant
issued 140 units, each unit consisting of a note in the principal amount of
$50,000 and warrants to purchase 25,000 shares of Class A Common Stock at an
exercise price of $3.00 per share (the "Bridge Warrants") to 166 accredited
investors for an aggregate purchase price of $7,000,000. The Bridge Warrants
will be converted on the closing of the Offering into 3,500,000 Class A
Warrants. D.H. Blair Investment Banking Corp. acted as the placement agent for
the Bridge Financing and, in that capacity, received a commission of $560,000
and a $210,000 nonaccountable expense allowance. The securities were issued in
reliance on Section 4(2) of the Securities Act.
 
    In May 1996, the Registrant agreed to issue 577,823 shares of Class B Common
Stock, 1,155,647 shares of Class E-1 Common Stock and 1,155,647 shares of Class
E-2 Common Stock to Dr. Carl Chen, the Chairman. Chief Executive Officer and
President of the Registrant, pursuant to, and in connection with the termination
of, the New Management Agreement effective as of January 29, 1995 between the
Registrant and Dr. Chen. The shares were issued to Dr. Chen in June 1996 in
reliance on Section 4(2) of the Securities Act, and no commissions or discounts
were paid.
 
    In May 1996, the Registrant agreed to issue 187,118 shares of Class B Common
Stock, 374,236 shares of Class E-1 Common Stock, and 374,236 shares of Class E-2
Common Stock to Dr. Chen in exchange for the cancellation of loans in the
aggregate amount of $336,000. The shares were issued in June 1996 in reliance on
Section 4(2) of the Securities Act, and no commissions or discounts were paid.
 
    In May 1996, the Registrant authorized the issuance of 17,460 shares of
Class B Common Stock, 34,919 shares of Class E-1 Common Stock and 34,919 shares
of Class E-2 Common Stock to Gene Comfort, its Executive Vice President, in
consideration for Mr. Comfort's services to the Company. The securities were
issued on June 26, 1996 in reliance on Section 4(2) of the Securities Act, and
no commissions or discounts were paid.
 
    In December 1993, the Registrant and Mr. Song Gen Yeh, who was at the time a
principal stockholder and director of the Registrant, agreed that the Registrant
would issue 584,074 shares of Class B Common Stock, 1,168,148 shares of Class
E-1 Common Stock, and 1,168,148 shares of Class E-2 Common Stock of the Company
to Mr. Yeh in repayment of advances made by Mr. Yeh to the Company in the
aggregate amount of $10,478,000. Such shares were issued to Mr. Yeh in June
1996. Also in June 1996, Mr. Yeh was issued 13,937 shares of Class B Common
Stock, 27,873 shares of Class E-1 Common Stock, and 27,873 shares of Class E-2
Common Stock of the Registrant in repayment of $250,000 in additional advances
made by Mr. Yeh to the Company. The foregoing shares were issued in reliance
upon Section 4(2) of the Securities Act, and no commissions or discounts were
paid. In August 1996, Mr. Yeh transferred all of the shares of the Registrant
held by him to Harpa Limited, a corporation organized under the laws of the
Cayman Islands ("Harpa"). C.M. Cheng, a director of the Registrant, is the
Director of Harpa and thus has voting control of the shares of the Registrant
held by Harpa. The voting control of Harpa is held equally by Shih Jen Yeh and
Chyao Chi Yeh, who are sons of Song Gen Yeh.

ITEM 28.  UNDERTAKINGS
 
    The Registrant hereby undertakes:
 
    (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement: (i) to include any
prospectus required by Section 10(a)(3) of the Securities Act; (ii) to reflect
in the prospectus any facts or events arising after the effective date of the
registration statement (or the most recent post-effective amendment thereof)
which, individually or in the aggregate, represent a fundamental change in the
information in the registration statement; and (iii) to include any additional
or changed material information with respect to the plan of distribution.
 
    (2) For the purpose of determining any liability under the Securities Act,
each post-effective amendment that contains a form of prospectus shall be deemed
to be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.
 
    (3) To remove from registration by means of post-effective amendment any of
the securities being registered which remain unsold at the termination of the
offering.
 
                                      II-3
<PAGE>
    (4) To provide to the underwriter at the closing specified in the
underwriting agreements certificates in such denominations and registered in
such names as required by the underwriter to permit prompt delivery to each
purchaser.
 
    (5) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding in connection with
the securities being registered), the registrant will, unless in the opinion of
its counsel the matter has been settled by controlling precedent, submit to a
court of appropriate jurisdiction the question whether such indemnification by
it is against public policy as expressed in the Securities Act and will be
governed by the final adjudication of such issue.
 
    (6) The undersigned Registrant hereby undertakes that it will:
 
        (a) For determining any liability under the Securities Act, treat the
    information omitted from the form of prospectus filed as part of this
    Registration Statement in reliance upon Rule 430A and contained in a form of
    prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4), or
    497(h) under the Securities Act as part of this registration statement as of
    the time it was declared effective.
 
        (b) For determining any liability under the Securities Act, treat each
    post-effective amendment that contains a form of prospectus as a new
    registration statement for the securities offered in the registration
    statement, and the offering of such securities at that time as the initial
    BONA FIDE offering of those securities.

(the "Underwriter"), an aggregate of 5,000,000 Units, each unit being
hereinafter referred to as a "Unit" and consisting of one share of Class A
Common Stock, par value $.0001 per share, ("Shares"), one redeemable Class A

Warrant").  Each Class A Warrant is exercisable to purchase one share of Common

___________, 2001.  Each Class B Warrant is exercisable to purchase one share of
Class A Common Stock at a price of $8.75 from __________ , 1996 to ___________ ,
2001.  The Class A Warrants and Class B Warrants are collectively referred to as
the "Warrants".  The Warrants are subject to redemption, in certain instances
commencing one year from the date of this Agreement.  In addition, the Company
proposes to grant to the Underwriter the option referred to in Section 2(b) to
purchase all or any part of an aggregate of 750,000 additional Units.  Unless
the context otherwise indicates, the term "Units" shall include the 750,000
additional Units referred to above.

         The aggregate of 5,000,000 Units to be sold by the Company, together
with all or any part of the 750,000 Units which the Underwriter has the option
to purchase, and the Shares and the Warrants comprising such Units, are herein
called the "Units." The Class A Common Stock of the Company to be outstanding
after giving effect to the sale of the Shares is herein called the "Class A
Common Stock." The Shares and Warrants included in the Units (including the
Units which the Underwriter has the option to purchase) are herein collectively
called the "Securities."


<PAGE>

         You have advised the Company that you desire to purchase the Units.
The Company confirms the agreements made by it with respect to the purchase of
the Units by you as follows:

         1.   REPRESENTATIONS AND WARRANTIES OF THE COMPANY.  The Company
represents and warrants to, and agrees with, the Underwriter that:

              (a)  A registration statement (File No. 33-  ) on Form SB-2
relating to the public offering of the Units, including a form of prospectus
subject to completion, copies of which have heretofore been delivered to you,
has been prepared by the Company in conformity with the requirements of the
Securities Act of 1933, as amended (the "Act"), and the rules and regulations
(the "Rules and Regulations") of the Securities and Exchange Commission (the
"Commission") thereunder, and has been filed with the Commission under the Act
and one or more amendments to such registration statement may have been so
filed.  After the execution of this Agreement, the Company will file with the
Commission either (i) if such registration statement, as it may have been
amended, has been declared by the Commission to be effective under the Act,
either (A) if the Company relies on Rule 434 under the Act, a Term Sheet (as
hereinafter defined) relating to the Units that shall identify the Preliminary
Prospectus (as hereinafter defined) that it supplements containing such
information as is required or permitted by Rules 434, 430A and 424(b) under the
Act or (B) if the Company does not rely on Rule 434 under the Act a prospectus
in the form most recently included in an amendment to such registration
statement (or, if no such amendment shall have been filed, in such registration
statement), with such changes or insertions as are required by Rule 430A under
the Act or permitted by Rule 424(b) under the Act and in the case of either
clause (i)(A) or (i)(B) of this sentence, as have been provided to and approved
by you prior to the execution of this Agreement, or (ii) if such registration
statement, as it may have been amended, has not been declared by the Commission
to be effective under the Act, an amendment to such registration statement,
including a form of prospectus, a copy of which amendment shall be furnished to
and approved by you prior to the execution of this Agreement.

         As used in this Agreement, the term "Registration Statement" means
such registration statement, as amended at the time when it was or is declared
effective, including all financial schedules and exhibits thereto and including
any information omitted therefrom pursuant to Rule 430A under the Act and
included in the Prospectus (as hereinafter defined); the term "Preliminary
Prospectus" means each prospectus subject to completion filed with such
registration statement or any amendment thereto (including the prospectus
subject to completion, if any, included in the Registration Statement or any
amendment thereto at the time it was or is declared effective); the term
"Prospectus" means (A) if the Company relies on Rule 434 under the Act, the Term
Sheet relating to the Shares and Warrants that is first filed pursuant to Rule
424(b)(7) under the Act, together with the Preliminary Prospectus identified
therein that such Term Sheet supplements; (B) if the Company does not rely on
Rule 434 under the Act, the prospectus first filed with the Commission pursuant
to Rule 424(b) under the Act or (C) if the Company does not rely on Rule 434
under the Act and if no prospectus is required to be filed pursuant to said
Rule 424(b), such term means the prospectus included in the Registration


                                         -2-

<PAGE>

Statement; except that if such registration statement or prospectus is amended
or such prospectus is supplemented, after the effective date of such
registration statement and prior to the Option Closing Date (as hereinafter
defined), the terms "Registration Statement" and "Prospectus" shall include such
registration statement and prospectus as so amended, and the term "Prospectus"
shall include the prospectus as so supplemented, or both, as the case may be;
and the term "Term Sheet" means any term sheet that satisfies the requirements
of Rule 434 under the Act.  Any reference to the "date" of a Prospectus that
includes a Term Sheet shall mean the date of such Term Sheet.

              (b)  The Commission has not issued any order preventing or
suspending the use of any Preliminary Prospectus.  At the time the Registration
Statement becomes effective and at all times subsequent thereto up to and on the
Closing Date (as hereinafter defined) or the Option Closing Date, as the case
may be, (i) the Registration Statement and Prospectus will in all respects
conform to the requirements of the Act and the Rules and Regulations; and
(ii) neither the Registration Statement nor the Prospectus will include any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary to make statements therein not misleading;
provided, however, that the Company makes no representations, warranties or
agreements as to information contained in or omitted from the Registration
Statement or Prospectus in reliance upon, and in conformity with, written
information furnished to the Company by or on behalf of the Underwriter
specifically for use in the preparation thereof.  It is understood that the
statements set forth in the Prospectus on page 2 with respect to stabilization,
under the heading "Underwriting" and the identity of counsel to the Underwriter
under the heading "Legal Matters" constitute the only information furnished in
writing by or on behalf of the Underwriter for inclusion in the Registration
Statement and Prospectus, as the case may be.

              (c)  The Company has been duly incorporated and is validly
existing as a corporation in good standing under the laws of the jurisdiction of
its incorporation, with full power and authority (corporate and other) to own
its properties and conduct its business as described in the Prospectus and is
duly qualified to do business as a foreign corporation and is in good standing
in all other jurisdictions in which the nature of its business or the character
or location of its properties requires such qualification, except where failure
to so qualify will not materially affect the Company's business, properties or
financial condition.

              (d)  The authorized, issued and outstanding capital stock of the
Company as of June 30, 1996 is as set forth in the Prospectus under
"Capitalization"; the shares of issued and outstanding capital stock of the
Company set forth thereunder have been duly authorized, validly issued and are
fully paid and non-assessable; except as set forth in the Prospectus, no
options, warrants, or other rights to purchase, agreements or other obligations
to issue, or agreements or other rights to convert any obligation into, any
shares of capital stock of the Company have been granted or entered into by the
Company; and the capital stock conforms to all statements relating thereto
contained in the Registration Statement and Prospectus.

<PAGE>

              (e)  The Units and the Shares are duly authorized, and when
issued and delivered pursuant to this Agreement, will be duly authorized,
validly issued, fully paid and nonassessable and free of preemptive rights of
any security holder of the Company.  Neither the filing of the Registration
Statement nor the offering or sale of the Units as contemplated in this
Agreement gives rise to any rights, other than those which have been waived or
satisfied, for or relating to the registration of any shares of Common Stock,
except as described in the Registration Statement.

         The Warrants have been duly authorized and, when issued and delivered
pursuant to this Agreement, will have been duly executed, issued and delivered
and will constitute valid and legally binding obligations of the Company
enforceable in accordance with their terms and entitled to the benefits provided
by the warrant agreement pursuant to which such Warrants are to be issued (the
"Warrant Agreement"), which will be substantially in the form filed as an
exhibit to the Registration Statement.  The shares of Class A Common Stock
issuable upon exercise of the Warrants have been reserved for issuance upon the
exercise of the Warrants and when issued in accordance with the terms of the
Warrants and Warrant Agreement, will be duly and validly authorized, validly
issued, fully paid and non-assessable and free of preemptive rights and no
personal liability will attach to the ownership thereof.  The Warrant Agreement
has been duly authorized and, when executed and delivered pursuant to this
Agreement, will have been duly executed and delivered and will constitute the
valid and legally binding obligation of the Company enforceable in accordance
with its terms.  The Warrants and the Warrant Agreement conform to the
respective descriptions thereof in the Registration Statement and Prospectus.

         The Shares and the Warrants contained in the Unit Purchase Option have
been duly authorized and, when duly issued and delivered, such Warrants will
constitute valid and legally binding obligations of the Company enforceable in
accordance with their terms and entitled to the benefits provided by the Unit
Purchase Option.  The Shares included in the Unit Purchase Option (and the
shares of Common Stock issuable upon exercise of such Warrants) when issued and
sold, will be duly authorized, validly issued, fully paid and non-assessable and
free of preemptive rights and no personal liability will attach to the ownership
thereof.

              (f)  This Agreement, the Unit Purchase Option and the M/A
Agreement have been duly and validly authorized, executed and delivered by the
Company.  The Company has full power and lawful authority to authorize, issue
and sell the Units to be sold by it hereunder on the terms and conditions set
forth herein, and no consent, approval, authorization or other order of any
governmental authority is required in connection with such authorization,
execution and delivery or with the authorization, issue and sale of the Units or
the Unit Purchase Option, except such as may be required under the Act or state
securities laws.

              (g)  Except as described in the Prospectus, the Company is not in
violation, breach or default of or under, and consummation of the transactions
herein contemplated and the fulfillment of the terms of this Agreement will not

mortgage, deed of trust, loan agreement or other agreement or instrument to
which the Company is a party or by which the Company may be bound or to which

result in any violation of the provisions of the articles of incorporation or
the by-laws of the Company, as amended, or any statute or any order, rule or
regulation applicable to the Company of any court or of any regulatory authority
or other governmental body having jurisdiction over the Company.

              (h)  Subject to the qualifications stated in the Prospectus, the

under which the Company is the lessor or sublessor of properties or assets or
under which the Company holds properties or assets as lessee or sublessee as
described in the Prospectus are in full force and effect, and, except as
described in the Prospectus, the Company is not in default in any material
respect with respect to any of the terms or provisions of any of such leases or
subleases, and no claim has been asserted by anyone adverse to rights of the
Company as lessor, sublessor, lessee or sublessee under any of the leases or
subleases mentioned above, or affecting or questioning the right of the Company

such lease or sublease except as described or referred to in the Prospectus; and
the Company owns or leases all such properties described in the Prospectus as

              (j)  The financial statements, together with related notes, set

recent Preliminary Prospectus) or the Registration Statement present fairly the
financial position and results of operations and changes in cash flow position
of the Company on the basis stated in the Registration Statement, at the
respective dates and for the respective periods to which they apply.  Said
statements and Schedules and related notes have been prepared in accordance with
generally accepted accounting principles applied on a basis which is consistent
during the periods involved.  The information set forth under the captions
"Dilution", "Capitalization", and "Selected Financial Data" in the Prospectus
fairly present, on the basis stated in the Prospectus, the information included
therein.  The pro forma financial information filed as part of the Registration
Statement or included in the Prospectus (or preliminary prospectus) has been

to pro forma financial statements, and includes all adjustments necessary to
present fairly the pro forma financial condition and results


                                         -5-

of operations at the respective dates and for the respective periods indicated
and all assumptions used in preparing such pro forma financial statements are
reasonable.

              (k)  Subsequent to the respective dates as of which information
is given in the Registration Statement and Prospectus (or, if the Prospectus is
not in existence, the most recent Preliminary Prospectus), the Company has not
incurred any liabilities or obligations, direct or contingent, not in the
ordinary course of business, or entered into any transaction not in the ordinary
course of business, which is material to the business of the Company, and there
has not been any change in the capital stock of, or any incurrence of short-term
or long-term debt by, the Company or any issuance of options, warrants or other
rights to purchase the capital stock of the Company or any adverse change or any
development involving, so far as the Company can now reasonably foresee a
prospective adverse change in the condition (financial or other), net worth,
results of operations, business, key personnel or properties of it which would
be material to the business or financial condition of the Company and the
Company has not become a party to, and neither the business nor the property of
the Company has become the subject of, any material litigation whether or not in
the ordinary course of business.

              (l)  Except as set forth in the Prospectus, there is not now
pending or, to the knowledge of the Company, threatened, any action, suit or
proceeding to which the Company is a party before or by any court or
governmental agency or body, which might result in any material adverse change

properties of the Company, nor are there any actions, suits or proceedings
related to environmental matters or related to discrimination on the basis of
age, sex, religion or race; and no labor disputes involving the employees of the
Company exist or are imminent which might be expected to adversely affect the
conduct of the business, property or operations or the financial condition or
results of operations of the Company.

              (m)  Except as disclosed in the Prospectus, the Company has filed
all necessary federal, state and foreign income and franchise tax returns and
has paid all taxes shown as due thereon; and there is no tax deficiency which
has been or to the knowledge of the Company might be asserted against the
Company.

              (n)  The Company has sufficient licenses, permits and other
governmental authorizations currently required for the conduct of its business
or the ownership of its properties as described in the Prospectus and is in all
material respects complying therewith and owns or possesses adequate rights to
use all material patents, patent applications, trademarks, service marks,
trade-names, trademark registrations, service mark registrations, copyrights and
licenses necessary for the conduct of such business and had not received any
notice of conflict with the asserted rights of others in respect thereof.  To
the best knowledge of the Company, none of the activities or business of the
Company are in violation of, or cause the Company to violate, any law, rule,
regulation or order of the United States, any state, county or locality, or of
any agency or body of the United States or of any state, county or locality, the
violation of which would have a material adverse impact upon the condition
(financial or otherwise), business, property, prospective results of operations,
or net worth of the Company.

         3.   COVENANTS OF THE COMPANY.  The Company covenants and agrees with
the Underwriter that:

              (a)  The Company will use its best efforts to cause the
Registration Statement to become effective as promptly as possible.  If
required, the Company will file the Prospectus or any Term Sheet that
constitutes a part thereof and any amendment or supplement thereto with the
Commission in the manner and within the time period required by Rules 434 and
424(b) under the Act.  Upon notification from the Commission that the
Registration Statement has become effective, the Company will so advise you and
will not at any time, whether before or after the effective date, file the
Prospectus, Term Sheet or any amendment to the Registration Statement or
supplement to the Prospectus of which you shall not previously have been advised
and furnished with a copy or to which you or your counsel shall have objected in
writing or which is not in compliance with the Act and the Rules and
Regulations.  At any time prior to the later of (A) the completion by the
Underwriter of the distribution of the Units contemplated hereby (but in no
event more than nine months after the date on which the Registration Statement
shall have become or been declared effective) and (B) 25 days after the date on
which the Registration Statement shall have become or been declared effective,
the Company will prepare and file with the Commission, promptly upon your
request, any amendments or supplements to the Registration Statement or
Prospectus which, in your opinion, may be necessary or advisable in connection
with the distribution of the Units.

              As soon as the Company is advised thereof, the Company will
advise you, and confirm the advice in writing, of the receipt of any comments of
the Commission, of the


                                         -9-

<PAGE>

effectiveness of any post-effective amendment to the Registration Statement, of
the filing of any supplement to the Prospectus or any amended Prospectus, of any
request made by the Commission for amendment of the Registration Statement or
for supplementing of the Prospectus or for additional information with respect
thereto, of the issuance by the Commission or any state or regulatory body of
any stop order or other order or threat thereof suspending the effectiveness of
the Registration Statement or any order preventing or suspending the use of any
preliminary prospectus, or of the suspension of the qualification of the Units
for offering in any jurisdiction, or of the institution of any proceedings for
any of such purposes, and will use its best efforts to prevent the issuance of
any such order, and, if issued, to obtain as soon as possible the lifting
thereof.

              The Company has caused to be delivered to you copies of each
Preliminary Prospectus, and the Company has consented and hereby consents to the
use of such copies for the purposes permitted by the Act.  The Company
authorizes the Underwriter and dealers to use the Prospectus in connection with
the sale of the Units for such period as in the opinion of counsel to the
Underwriter the use thereof is required to comply with the applicable provisions
of the Act and the Rules and Regulations.  In case of the happening, at any time
within such period as a Prospectus is required under the Act to be delivered in
connection with sales by an underwriter or dealer of any event of which the
Company has knowledge and which materially affects the Company or the securities
of the Company, or which in the opinion of counsel for the Company or counsel
for the Underwriter should be set forth in an amendment of the Registration
Statement or a supplement to the Prospectus in order to make the statements
therein not then misleading, in light of the circumstances existing at the time
the Prospectus is required to be delivered to a purchaser of the Units or in
case it shall be necessary to amend or supplement the Prospectus to comply with
law or with the Rules and Regulations, the Company will notify you promptly and
forthwith prepare and furnish to you copies of such amended Prospectus or of
such supplement to be attached to the Prospectus, in such quantities as you may
reasonably request, in order that the Prospectus, as so amended or supplemented,
will not contain any untrue statement of a material fact or omit to state any
material facts necessary in order to make the statements in the Prospectus, in
the light of the circumstances under which they are made, not misleading.  The
preparation and furnishing of any such amendment or supplement to the
Registration Statement or amended Prospectus or supplement to be attached to the
Prospectus shall be without expense to the Underwriter, except that in case any
Underwriter is required, in connection with the sale of the Units to deliver a
Prospectus nine months or more after the effective date of the Registration
Statement, the Company will upon request of and at the expense of the
Underwriter, amend or supplement the Registration Statement and Prospectus and
furnish the Underwriter with reasonable quantities of prospectuses complying
with Section 10(a)(3) of the Act.

              The Company will comply with the Act, the Rules and Regulations
and the Securities Exchange Act of 1934 and the rules and regulations thereunder
in connection with the offering and issuance of the Units.

              (b)  The Company will use its best efforts to qualify to register
the Units for sale under the securities or "blue sky" laws of such jurisdictions
as the Underwriter may designate and will make such applications and furnish
such information as may be required for that purpose and to comply with such
laws, provided the Company shall not be required to qualify as a foreign
corporation or a dealer in securities or to execute a general consent of service
of process in any jurisdiction in any action other than one arising out of the
offering or sale of the Units.  The Company will, from time to time, prepare and
file such statements and reports as are or may be required to continue such
qualification in effect for so long a period as the Underwriter may reasonably
request.

              (c)  If the sale of the Units provided for herein is not
consummated for any reason caused by the Company, the Company shall pay all
costs and expenses incident to the performance of the Company's obligations
hereunder, including but not limited to, all of the expenses itemized in
Section 8, including the accountable expenses of the Underwriter.

              (d)  The Company will use its best efforts to (i) cause a
registration statement under the Securities Exchange Act of 1934 to be declared
effective concurrently with the completion of this offering and will notify the
Underwriter in writing immediately upon the effectiveness of such registration
statement, and (ii) if requested by the Underwriter, to obtain a listing on the
Pacific Stock Exchange and to obtain and keep current a listing in the Standard
& Poors or Moody's Industrial OTC Manual.

              (e)  For so long as the Company is a reporting company under
either Section 12(g) or 15(d) of the Securities Exchange Act of 1934, the
Company, at its expense, will furnish to its stockholders an annual report
(including financial statements audited by independent public accountants), in
reasonable detail and at its expense, will furnish to you during the period
ending five (5) years from the date hereof, (i) as soon as practicable after the
end of each fiscal year, a balance sheet of the Company and any of its
subsidiaries as at the end of such fiscal year, together with statements of
income, surplus and cash flow of the Company and any subsidiaries for such
fiscal year, all in reasonable detail and accompanied by a copy of the
certificate or report thereon of independent accountants; (ii) as soon as
practicable after the end of each of the first three fiscal quarters of each
fiscal year, consolidated summary financial information of the Company for such

reports (financial or other) mailed to security holders; (iv) as soon as they
are available, a copy of all non-confidential reports and financial statements
furnished to or filed with the Commission or any securities exchange or
automated quotation system on which any class of securities of the Company is
listed; and (v) such other information as you may from time to time reasonably
request.

              (f)  In the event the Company has an active subsidiary or
subsidiaries, such financial statements referred to in subsection (e) above will
be on a consolidated basis to the extent the accounts of the Company and its
subsidiary or subsidiaries are consolidated in reports furnished to its
stockholders generally.

Units for the purposes set forth under "Use of Proceeds" in the Prospectus, and
will file such reports with the Commission with respect to the sale of the Units

Statement to become effective in compliance with the Act and without any lapse
of time between the effectiveness of any such post-effective amendments and
cause a copy of each Prospectus, as then amended, to be delivered to each holder
of record of a Warrant and to furnish to the Underwriter and dealer as many
copies of each such Prospectus as the Underwriter or dealer may reasonably
request.  The Company shall not call for redemption any of the Warrants unless a
registration statement covering the securities underlying the Warrants has been
declared effective by the Commission and remains current at least until the date

the aggregate exercise price of the Warrants, of which 1% may be reallowed to
the dealer who solicited the exercise (which may also be D.H. Blair Investment
Banking Corp.) if (i) the market price of the Company's Common Stock is greater
than the exercise price of the Warrants on the date of exercise; (ii) the
exercise of the Warrant was solicited in writing by a member of the National
Association of Securities Dealers, Inc., (iii) the Warrant is not held in a
discretionary account; (iv) the disclosure of compensation arrangements has been
made in documents provided to customers, both as part of the original offering
and at the time of exercise, and (v) the solicitation of the Warrant was not in
violation of Rule 10b-6 promulgated under the Securities Exchange Act of 1934,
as amended.  The Company agrees not to solicit the exercise of any Warrants
other than through D.H. Blair Investment Banking Corp. and will not authorize
any other dealer to engage in such solicitation without the prior written
consent of D.H. Blair Investment Banking Corp.

              (v)  For a period of five (5) years from the Effective Date the
Company (i) at its expense, shall cause its regularly engaged independent

the Underwriter shall have the right, but not the obligation, to designate one
director of the Board of Directors of the Company and (ii) the Company shall
engage a public relations firm acceptable to the Underwriter.

              (y)  The Company shall, for a period of six years after date of
this Agreement, submit which reports to the Secretary of the Treasury and to
stockholders, as the Secretary may require, pursuant to Section 1202 of the
Internal Revenue Code, as amended, or regulations promulgated thereunder, in
order for the Company to qualify as a "small business" so that stockholders may
realize special tax treatment with respect to their investment in the Company.

              (z)  With respect to the Selling Stockholders, the Company will
send all post-effective amendments or prospectus supplements disclosing actual
price and selling terms to the NASD concurrently with the filing thereof with
the Commission.  The Company will notify the Underwriter and the NASD if the
Company becomes aware that any 5% or greater stockholder of the Company becomes
an affiliated or associated person of an NASD member participating in the
distribution of this offering.

              reason to believe that the Registration Statement or any
              amendment thereto at the time it became effective or as of the
              Closing Dates contained any untrue statement of a material fact
              required to be stated therein or omitted to state any material
              fact required to be stated therein or necessary to make the
              statements therein not misleading or that the Prospectus or any
              supplement thereto contains any untrue statement of a material
              fact or omits to state a material fact necessary in order to make
              statements therein, in light of the circumstances under which
              they were made, not misleading (except, in the case of both the
              Registration Statement and any amendment thereto and the
              Prospectus and any supplement thereto, for the financial
              statements, notes thereto and other financial information and
              schedules contained therein, as to which such counsel need

              character required to be summarized or described therein or to be
              filed as exhibits thereto which are not so summarized, described
              or filed;

              state or foreign securities or Blue Sky laws and registration

              Closing Date pursuant to Section 4(b) and (c) hereof, except that
              such opinion, where appropriate, shall cover the Option Units.

              (iii)     At the Option Closing Date there shall have been
              delivered to you a certificate of the Chairman of the Board or
              the President and the

              principal financial or accounting officer of the Company, dated
              the Option Closing Date, in form and substance satisfactory to
              Bachner, Tally, Polevoy & Misher LLP, counsel to the Underwriter,
              substantially the same in scope and substance as the certificate
              furnished to you at the First Closing Date pursuant to
              Section 4(f) hereof.

               (iv)     At the Option Closing Date there shall have been
              delivered to you a letter in form and substance satisfactory to
              you from Price Waterhouse LLP, dated the Option Closing Date and
              addressed to the Underwriter confirming the information in their
              letter referred to in Section 4(f) hereof and stating that
              nothing has come to their attention during the period from the
              ending date of their review referred to in said letter to a date
              not more than five business days prior to the Option Closing
              Date, which would require any change in said letter if it were
              required to be dated the Option Closing Date.

                (v)     All proceedings taken at or prior to the Option Closing
              Date in connection with the sale and issuance of the Option Units
              shall be satisfactory in form and substance to you, and you and
              Bachner, Tally, Polevoy & Misher LLP, counsel to the Underwriter,
              shall have been furnished with all such documents, certificates,
              and opinions as you may request in connection with this
              transaction in order to evidence the accuracy and completeness of
              any of the representations, warranties or statements of the
              Company or its compliance with any of the covenants or conditions
              contained herein.

              (h)  No action shall have been taken by the Commission or the
NASD the effect of which would make it improper, at any time prior to the
Closing Date, for members of the NASD to execute transactions (as principal or
agent) in the Units, Common Stock or the Warrants and no proceedings for the
taking of such action shall have been instituted or shall be pending, or, to the
knowledge of the Underwriter or the Company, shall be contemplated by the
Commission or the NASD.  The Company represents that at the date hereof it has
no knowledge that any such action is in fact contemplated by the Commission or
the NASD.  The Company shall have advised the Underwriter of any NASD
affiliation of any of its officers, directors, stockholders or their affiliates.

              (i)  If any of the conditions herein provided for in this Section
shall not have been fulfilled as of the date indicated, this Agreement and all
obligations of the Underwriter under this Agreement may be cancelled at, or at
any time prior to, each Closing Date by the Underwriter.  Any such cancellation
shall be without liability of the Underwriter to the Company.

         5.   CONDITIONS OF THE OBLIGATIONS OF THE COMPANY.  The obligation of
the Company to sell and deliver the Units is subject to the condition that at
the Closing Dates, no


                                         -22-

<PAGE>

stop orders suspending the effectiveness of the Registration Statement shall
have been issued under the Act or any proceedings therefor initiated or
threatened by the Commission.

              If the condition to the obligations of the Company provided for
in this Section have been fulfilled on the First Closing Date but are not
fulfilled after the First Closing Date and prior to the Option Closing Date,
then only the obligation of the Company to sell and deliver the Units on
exercise of the option provided for in Section 2(b) hereof shall be affected.

         6.   INDEMNIFICATION.

              (a)  The Company agrees to indemnify and hold harmless the
Underwriter and each person, if any, who controls the Underwriter within the
meaning of the Act against any losses, claims, damages or liabilities, joint or
several (which shall, for all purposes of this Agreement, include, but not be
limited to, all reasonable costs of defense and investigation and all attorneys'
fees), to which the Underwriter or such controlling person may become subject,
under the Act or otherwise, and will reimburse, as incurred, such Underwriter
and such controlling persons for any legal or other expenses reasonably incurred
in connection with investigating, defending against or appearing as a third
party witness in connection with any losses, claims, damages or liabilities,
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 (A) the Registration Statement, any
Preliminary Prospectus, the Prospectus, or any amendment or supplement thereto,
(B) any blue sky application or other document executed by the Company
specifically for that purpose or based upon written information furnished by the
Company filed in any state or other jurisdiction in order to qualify any or all
of the Units under the securities laws thereof (any such application, document
or information being hereinafter called a "Blue Sky Application"), or arise out
of or are based upon the omission or alleged omission to state in the
Registration Statement, any Preliminary Prospectus, Prospectus, or any amendment
or supplement thereto, or in any Blue Sky Application, a material fact required
to be stated therein or necessary to make the statements therein not misleading;
provided, however, that the Company will not be liable in any such case to the
extent, but 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
written information furnished to the Company by or on behalf of the Underwriter
specifically for use in the preparation of the Registration Statement or any
such amendment or supplement thereof or any such Blue Sky Application or any
such preliminary Prospectus or the Prospectus or any such amendment or
supplement thereto.  This indemnity will be in addition to any liability which
the Company may otherwise have.

              (b)  The Underwriter will indemnify and hold harmless the
Company, each of its directors, each nominee (if any) for director named in the
Prospectus, each of its officers who have signed the Registration Statement, and
each person, if any, who controls the Company within the meaning of the Act,
against any losses, claims, damages or liabilities (which shall, for all
purposes of this Agreement, include, but not be limited to, all costs of defense
and


                                         -23-

<PAGE>

investigation and all attorneys' fees) to which the Company or any such
director, nominee, officer 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, any Preliminary Prospectus, the Prospectus, or any amendment or
supplement thereto, or arise out of or are based upon the omission or the
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, in each case to the
extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was made in the Registration
Statement, any Preliminary Prospectus, the Prospectus, or any amendment or
supplement thereto (i) in reliance upon and in conformity with written
information furnished to the Company by you specifically for use in the
preparation thereof and (ii) relates to the transactions effected by the
Underwriter in connection with the offer and sale of the Units contemplated
hereby.  This indemnity agreement will be in addition to any liability which the
Underwriter may otherwise have.

              (c)  Promptly after receipt by an indemnified party under this
Section of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Section, notify in writing the indemnifying party of the commencement
thereof; but the omission so to notify the indemnifying party will not relieve
it from any liability which it may have to any indemnified party otherwise than
under this Section.  In case any such action is brought against any indemnified
party, and it notifies the indemnifying party of the commencement thereof, the
indemnifying party will be entitled to participate in, and, to the extent that
it may wish, jointly with any other indemnifying party similarly notified, to
assume the defense thereof, subject to the provisions herein stated, with
counsel reasonably satisfactory to such indemnified party, and after notice from
the indemnifying party to such indemnified party of its election so to assume
the defense thereof, the indemnifying party will not be liable to such
indemnified party under this Section for any legal or other expenses
subsequently incurred by such indemnified party in connection with the defense
thereof other than reasonable costs of investigation.  The indemnified party
shall have the right to employ separate counsel in any such action and to
participate in the defense thereof, but the fees and expenses of such counsel
shall not be at the expense of the indemnifying party if the indemnifying party
has assumed the defense of the action with counsel reasonably satisfactory to
the indemnified party; provided that if the indemnified party is an Underwriter
or a person who controls such Underwriter within the meaning of the Act, the
fees and expenses of such counsel shall be at the expense of the indemnifying
party if (i) the employment of such counsel has been specifically authorized in
writing by the indemnifying party or (ii) the named parties to any such action
(including any impleaded parties) include both such Underwriter or such
controlling person and the indemnifying party and in the judgment of the
Underwriter, it is advisable for the Underwriter or controlling persons to be
represented by separate counsel (in which case the indemnifying party shall not
have the right to assume the defense of such action on behalf of such
Underwriter or such controlling person, it being understood, however, that the
indemnifying party shall not, in connection with any one such action or separate
but substantially similar or related actions in the same jurisdiction arising
out of the same general allegations or


                                         -24-

<PAGE>

circumstances, be liable for the reasonable fees and expenses of more than one
separate firm of attorneys for the Underwriter and controlling persons, which
firm shall be designated in writing by you).  No settlement of any action
against an indemnified party shall be made without the consent of the
indemnifying party, which shall not be unreasonably withheld in light of all
factors of importance to such indemnifying party.

         7.   CONTRIBUTION.

              In order to provide for just and equitable contribution under the
Act in any case in which the Underwriter makes claim for indemnification
pursuant to Section 6 hereof 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
the express provisions of Section 6 provide for indemnification in such case, or
(ii) contribution under the Act may be required on the part of the Underwriter,
then the Company and each person who controls the Company, in the aggregate, and
the Underwriter shall contribute to the aggregate losses, claims, damages or
liabilities to which they may be subject (which shall, for all purposes of this
Agreement, include, but not be limited to, all reasonable costs of defense and
investigation and all reasonable attorneys' fees) in either such case (after
contribution from others) in such proportions that the Underwriter is
responsible in the aggregate for that portion of such losses, claims, damages or
liabilities represented by the percentage that the underwriting discount per
Unit appearing on the cover page of the Prospectus bears to the public offering
price appearing thereon, and the Company shall be responsible for the remaining
portion, provided, however, that (a) if such allocation is not permitted by
applicable law then the relative fault of the Company and the Underwriter and
controlling persons, in the aggregate, in connection with the statements or
omissions which resulted in such damages and other relevant equitable
considerations shall also be considered.  The relative fault shall be determined
by reference to, among other things, whether in the case of an untrue statement
of a material fact or the omission to state a material fact, such statement or
omission relates to information supplied by the Company, or the Underwriter and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such untrue statement or omission.  The Company and the
Underwriter agree that it would not be just and equitable if the respective
obligations of the Company and the Underwriter to contribute pursuant to this
Section 7 were to be determined by pro rata or per capita allocation of the
aggregate damages (even if the Underwriter in the aggregate were treated as one
entity for such purpose) or by any other method of allocation that does not take
account of the equitable considerations referred to in the first sentence of
this Section 7.  No person guilty of a fraudulent misrepresentation (within the
meaning of Section 11(f) of the Act) shall be entitled to contribution from any
person who is not guilty of such fraudulent misrepresentation.  As used in this
paragraph, the word "Company" includes any officer, director, or person who
controls the Company within the meaning of Section 15 of the Act.  If the full
amount of the contribution specified in this paragraph is not permitted by law,
then the Underwriter and each person who controls the Underwriter shall be
entitled to contribution from the Company, its officers, directors and
controlling persons to the full extent permitted by law.  The foregoing
contribution agreement shall in no way affect the contribution


                                         -25-

<PAGE>

liabilities of any persons having liability under Section 11 of the Act other
than the Company and the Underwriter.  No contribution shall be requested with
regard to the settlement of any matter from any party who did not consent to the
settlement; provided, however, that such consent shall not be unreasonably
withheld in light of all factors of importance to such party.

         8.   COSTS AND EXPENSES.

              (a)  Whether or not this Agreement becomes effective or the sale
of the Units to the Underwriter is consummated, the Company will pay all costs
and expenses incident to the performance of this Agreement by the Company
including, but not limited to, the fees and expenses of counsel to the Company
and of the Company's accountants; the costs and expenses incident to the

supplemented, or the Term Sheet, the fee of the NASD in connection with the
filing required by the NASD relating to the offering of the Units contemplated
hereby; all expenses, including reasonable fees and disbursements of counsel to
the Underwriter, in connection with the qualification of the Units under the
state securities or blue sky laws which the Underwriter shall designate; the
cost of printing and furnishing to the Underwriter copies of the Registration

Agreement and the Blue Sky Memorandum, any fees relating to the listing of the
Units, Class A Common Stock and Warrants on the Nasdaq National Market or any
other securities exchange, the cost of printing the certificates representing
the securities comprising the Units, the fees of the transfer agent and warrant
agent the cost of publication of at least three "tombstones" of the offering (at
least one of which shall be in national business newspaper and one of which
shall be in a major New York newspaper) and the cost of preparing at least four
hard cover "bound volumes" relating to the offering, in accordance with the
Underwriter's request.  The Company shall pay any and all taxes (including any
transfer, franchise, capital stock or other tax imposed by any jurisdiction) on
sales to the Underwriter hereunder.  The Company will also pay all costs and
expenses incident to the furnishing of any amended Prospectus or of any
supplement to be attached to the Prospectus as called for in Section 3(a) of
this Agreement except as otherwise set forth in said Section.

              (b)  In addition to the foregoing expenses the Company shall at
the First Closing Date pay to D.H. Blair Investment Banking Corp., a
non-accountable expense allowance of $750,000 of which $40,000 has been paid.
In the event the overallotment option is exercised, the Company shall pay to
D.H. Blair Investment Banking Corp. at the Option Closing Date an additional
amount equal to 3% of the gross proceeds received upon exercise of the
overallotment option.  In the event the transactions contemplated hereby are not
consummated by reason of any action by the Underwriter (except if such
prevention is based upon a breach by the Company of any covenant, representation
or warranty contained herein or because any other condition to the Underwriter's
obligations hereunder required to be fulfilled by the Company is not fulfilled)
the Company shall be liable for the accountable expenses of the Underwriter,
including legal fees up to a maximum of $40,000.  In the event the transactions
contemplated hereby are not consummated by reason of any action of the Company
or because of a breach by


                                         -26-

<PAGE>

the Company of any covenant, representation or warranty herein, the Company
shall be liable for the accountable expenses of the Underwriter, including legal
fees, up to a maximum of $540,000.

              (c)  No person is entitled either directly or indirectly to
compensation from the Company, from the Underwriter or from any other person for
services as a finder in connection with the proposed offering, and the Company
agrees to indemnify and hold harmless the Underwriter, against any losses,
claims, damages or liabilities, joint or several (which shall, for all purposes
of this Agreement, include, but not be limited to, all costs of defense and
investigation and all attorneys' fees), to which the Underwriter or person may
become subject insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon the claim of any
person (other than an employee of the party claiming indemnity) or entity that
he or it is entitled to a finder's fee in connection with the proposed offering
by reason of such person's or entity's influence or prior contact with the
indemnifying party.

         9.   EFFECTIVE DATE.

              The Agreement shall become effective upon its execution except
that you may, at your option, delay its effectiveness until 11:00 A.M., New York

Registration Statement, or at such earlier time after the effective date of the
Registration Statement as you in your discretion shall first commence the
initial public offering by the Underwriter of any of the Units.  The time of the
initial public offering shall mean the time of release by you of the first
newspaper advertisement with respect to the Units, or the time when the Units
are first generally offered by you to dealers by letter or telegram, whichever
shall first occur.  This Agreement may be terminated by you at any time before

14 and 15 hereof, may be terminated at any time prior to the First Closing Date,
and the option referred to in Section 2(b) hereof, if exercised, may be
cancelled at any time prior to the Option Closing Date, by you if in your
judgment it is impracticable to offer for sale or to enforce contracts made by
the Underwriter for the resale of the Units agreed to be purchased hereunder by
reason of (i) the Company having sustained a material loss, whether or not
insured, by reason of fire, earthquake, flood, accident or other calamity, or
from any labor dispute or court or government action, order or decree;
(ii) trading in securities on the New York Stock Exchange, the American Stock

been received by the Company of the threat of any such proceeding or action,
which could materially adversely affect the Company; (vii) except as
contemplated by the Prospectus, the Company is merged or consolidated into or
acquired by another company or group or there exists a binding legal commitment

legislative body or federal or state agency or other authority of any act, rule

Representative to have a material impact on the business, financial condition or
financial statements of the Company or the market for the securities offered
pursuant to the Prospectus; (ix) any adverse change in the financial or
securities markets beyond normal market fluctuations having occurred since the
date of this Agreement, or (x) any material adverse change having occurred,
since the respective dates of which information is given in the Registration
Statement and Prospectus, in the earnings, business prospects or general
condition of the Company, financial or otherwise, whether or not arising in the
ordinary course of business.

              (b)  If you elect to prevent this Agreement from becoming
effective or to terminate this Agreement as provided in this Section 10 or in
Section 9, the Company shall be promptly notified by you, by telephone or
telegram, confirmed by letter.

         11.  UNIT PURCHASE OPTION.

              At or before the First Closing Date, the Company will sell to

          (B)  Class B Common Stock

               (1)  Subject to the limitations of subparagraph (6) below, all
               outstanding shares of Class B Common Stock, at the election of
               the holder thereof, shall be convertible into an equal number of
               fully paid and nonassessable shares of Class A Common Stock by
               delivery of written notice by the holder of such shares of Class
               B Common Stock to this corporation, or its transfer agent, of his
               or her election together with the certificate(s) representing the
               shares to be converted (and shall reflect any previously declared
               stock splits, dividends or recapitalizations of Class A Common
               Stock).  Thereupon, the corporation, or its transfer agent, as
               the case may be, shall exchange such certificate(s) for a
               certificate or certificates representing an equal number of
               shares of Class A Common Stock.  Shares of Class B Common Stock
               shall be deemed to have been converted immediately prior to the
               close of business on the day upon which the corporation, or its
               transfer agent, receives the certificate for such shares for
               conversion.  The person entitled to receive the Class A Common
               Stock issuable upon such conversion shall be treated for all
               purposes as the record holder of such Class A Common Stock at
               such time.

               (2)  Except as provided in subparagraph (3) below, upon the sale,
               assignment, transfer, conveyance, or other disposition, whether
               voluntary, by

               operation of law or otherwise (a "Transfer"), of shares of Class
               B Common Stock, other than a transfer to another holder of Class
               B Common Stock, the shares so transferred shall, by virtue of
               such Transfer, automatically be converted into an equal number of
               fully paid and nonassessable shares of Class A Common Stock.

               (3)  Upon the death of any holder of Class B Common Stock, the
               shares of Class B Common Stock so held as of the date of death of
               the deceased stockholder shall be automatically converted into an
               equal number of fully paid and nonassessable shares of Class A
               Common Stock unless and to the extent that any of such shares are
               purchased by another holder of Class B Common Stock on or prior
               to 90 days from a date that a legal representative is duly
               appointed by a court of competent jurisdiction, or 120 days from
               such date if within such 90-day period another holder of Class B
               Common Stock has exercised any right to purchase shares of Class
               B Common Stock held by such legal representative.  If there
               should be only one holder of Class B Common Stock, effective
               immediately upon his death, the shares of Class B Common Stock so
               held as of the date of death shall be automatically converted
               into an equal number of fully paid and nonassessable shares of
               Class A Common Stock.

               into Class A Common Stock pursuant to subparagraphs (2) and (3)
               above, until surrender as hereinafter provided, each outstanding
               certificate, which prior to such conversion represented shares of
               Class B Common Stock, shall be deemed for all purposes to
               evidence ownership of the number of shares of Class A Common
               Stock into which the shares of Class B Common Stock shall have
               been converted.  Upon surrender to this corporation, or its
               transfer agent, for cancellation of the certificate or
               certificates representing such shares, the holder thereof shall
               be entitled to receive a certificate or certificates representing
               the number of shares of Class A Common Stock to which such holder
               is entitled.

               (5)  With respect to any shares of Class B Common Stock converted
               into Class A Common Stock pursuant to subparagraphs (1), (2) or
               (3) above, such converted shares of Class B Common Stock shall,
               after the date of conversion, have the status of authorized but
               unissued shares of Class B Common Stock, but may not be reissued.

               (6)  Holders of Class B Common Stock shall be prohibited, without
               prior written consent of this corporation, from selling,
               assigning, transferring, conveying, converting pursuant to
               subparagraph (1) above, or otherwise disposing of their shares of
               Class B Common Stock for thirteen (13) months

                         at the place where the principal office of the
                         corporation is located.  The notice shall state the
                         date for redemption and the Redemption Price and shall
                         require the holder to surrender to the corporation, on

                    (b)  On or after the date fixed for redemption, each holder
                         of shares of Class E Common Stock called for redemption
                         shall, if those shares are certificated, surrender the
                         certificate evidencing the shares to the corporation at
                         the place designated in the redemption notice and shall
                         at that time be entitled to receive payment of the
                         Redemption Price.  If less 

                                       13
<PAGE>

                         than all shares represented by any surrendered
                         certificate are redeemed, a new certificate for the
                         unredeemed shares shall be issued.  If the redemption
                         notice is duly given and if sufficient funds are
                         available on the date fixed for redemption to pay the
                         Redemption Price, then, whether or not the certificates
                         evidencing the shares of Class E Common Stock to be
                         redeemed are surrendered, all rights with respect to
                         those shares so called for redemption shall cease and
                         terminate as of the date fixed for redemption, except
                         the right of the holders to receive the Redemption
                         Price, without interest, on surrender of their
                         certificates, if those shares are certificated.

               (9)  The "Minimum Pretax Income" amounts set forth above assume
               the  the conversion into Class B Common Stock of all of the
               shares of Class E Common Stock and the conversion into Class A
               Common Stock of any outstanding shares of Class B Common Stock
               and any other securities which are convertible into Class A
               Common Stock solely upon surrender of such convertible securities
               without the payment of any additional consideration, but shall be
               increased proportionally to reflect the issuance of any other
               additional shares, including any shares that may be issued upon
               the exercise of any warrants or options presently outstanding or
               hereafter granted, provided, however, that, with respect to any
               shares of Class A Common Stock issued 

                                       14
<PAGE>

               upon exercise of warrants initially subject to the Registration
               Statement, so long as any portion of the net proceeds received by
               the corporation upon such exercise is not utilized by the
               Company, but such proceeds (the "Invested Proceeds") are instead
               invested in short-term, high grade interest bearing securities or
               accounts or securities issued or guaranteed by the United States
               government, then the adjustment to the Minimum Pretax Income
               amounts set forth above with respect to that number of warrants
               which generated such Invested Proceeds shall be equal to 8% per
               annum multiplied by such amount of Invested Proceeds.  The
               Minimum Pretax Income shall be calculated exclusive of any
               extraordinary earnings or extraordinary charges, including, but
               not limited to, any charge to income resulting from the
               conversion of  shares of Class E Common Stock (all as audited and
               determined by the corporation's independent public accountants).

     5.   The board of directors is authorized to make, alter or repeal the
bylaws of the corporation.  Election of directors need not be by written ballot.

     6.   The provisions set forth in this Article 6 and in Article 4(B) and
4(C) of this Certificate of Incorporation may not be repealed or amended in any
respect unless such action is approved by the affirmative vote of the holders of
all of the outstanding shares of the Common Stock of the corporation.

of Long Beach, State of California, or at such place as may be fixed from time
to time by the board of directors, or at such other place either within or
without the State of Delaware as shall be designated from time to time by the
board of directors and stated in the notice of the meeting.  Meetings of

    Section 2.  Annual meetings of stockholders, commencing with the year 1997,

    Section 3.  The officer who has charge of the stock ledger of the
corporation shall prepare and make, at least ten days before every meeting of

directors, or by the chairman of the board, or by the president, or at the
request in writing of stockholders owning at least ten percent of the entire
capital stock of the corporation issued and outstanding and entitled to vote.
Such request shall state the purpose or purposes of the proposed meeting.

    Section 5.  Business transacted at any special meeting of stockholders
shall be limited to the purposes stated in the notice.

    Section 6.  Written notice of any meeting of stockholders stating the
place, date and hour of the meeting and the purpose or purposes for which the

(60) days before the date of the meeting, to each stockholder entitled to vote
at such meeting.   Any notice of stockholders' meeting or report to stockholders
shall be deemed to have been given at the time when delivered personally or
deposited in the mail (first class, postage pre-paid) or sent by other means of
written communication.  An affidavit of mailing of any notice or report in
accordance with the provisions of the General Corporation Law of Delaware
(DGCL), executed by the Secretary, assistant secretary or any transfer agent,
shall be prima facie evidence of the giving of the notice or report.

    Section 7.  Upon request in writing, delivered to such officers by any
persons entitled to call a meeting of stockholders, it shall be the duty of the
chairman of the board, the president, a vice president or the secretary, to
cause notice to be given to the stockholders entitled to vote that a meeting
will be held at a time requested by the person or persons calling the meeting,
not less than thirty-five (35) nor more than sixty (60) days after receipt of
the request.  If such notice shall not be given within twenty (20) days after
the date of receipt of such request, the person of persons entitled to call the
meeting may give notice of the meeting in the manner provided in Section 8 of
Article II of these Bylaws.

    Section 8.  Notice of each annual or special meeting of stockholders shall
be given in writing and shall specify the place, the date and the hour of the
meeting, and (1) in the case of a special meeting, the general nature of the
business to be transacted at the meeting, or (2) in the case of the annual
meeting, those matters which the board of directors, at the time of the mailing
of the notice, intends to present for action by the stockholders, but, any
proper matter may be presented at the annual meeting for such action.

    Section 9.  Notice of a stockholders' meeting or any report to he
stockholders shall be given either personally, or by sending a copy thereof

                                          2

<PAGE>

books of the corporation, or given by the stockholder to the corporation for the
purposes of notice; or, if no such address appears or is given, notice shall be
deemed to have been given if addressed to the stockholder at the place where the
principal executive office of the corporation is located or if published at
least once in a newspaper having general circulation in the county in which the
principal executive office is located.  If any notice or report addressed to the
stockholder at the address of such stockholder appearing on the books of the
corporation is returned to the corporation by the United States Postal Service
marked to indicate that the United States Postal Service is unable to deliver
the notice or report to the stockholder at such address, all future notices or
reports shall be deemed to have been duly given without further mailing if the
same shall be available for the stockholder upon written demand of the
stockholder at the principal executive office of the corporation for a period of
one year from the date of the giving of the notice or report to all other
stockholders.

    Section 10.  The holders of a majority of the stock issued and outstanding
and entitled to vote thereat, present in person or represented by proxy, shall
constitute a quorum at all meetings of the stockholders for the transaction of
business except as otherwise provided by statute or by the certificate of
incorporation.  Whenever under the DGCL, shares are disqualified from voting on
any matter, they shall not be considered outstanding for the determination of a
quorum at any meeting to act upon that matter.  The stockholders present at a
duly called or held meeting at which a quorum is present may continue to
transact business until adjournment notwithstanding the withdrawal of enough
stockholders to leave less than a quorum, if any action taken (other than
adjournment) is approved by at least a majority of the shares required to
constitute a quorum.  If, however, such quorum shall not be present or
represented at any meeting of the stockholders, the stockholders entitled to
vote thereat, present in person or represented by proxy, shall have power to
adjourn the meeting from time to time, without notice other than announcement at
the meeting, until a quorum shall be present or represented.  At such adjourned
meeting at which a quorum shall be present or represented any business may be
transacted which might have been transacted at the meeting as originally
notified.  If the adjournment is for more than thirty days, or if after the
adjournment a new record date is fixed for the adjourned meeting, a notice of
the adjourned meeting shall be given to each stockholder of record entitled to
vote at the meeting.

    Section 11.  When a quorum is present at any meeting, the vote of the
holders of a majority of the stock having voting power present in person or
represented by proxy shall decide any question brought before such meeting,
unless the question is one upon which by express provision of the statutes or of
the certificate of incorporation, a different vote is required in which case
such express provision shall govern and control the decision of such question.

    Section 12.  Unless otherwise provided in the certificate of incorporation
each stockholder shall at every meeting of the stockholders be entitled to one
vote in person or by proxy for each share of the capital stock having voting
power held by such stockholder, but in the election of directors, cumulative
voting shall prevail, that is to say, each stockholder shall have the right to
cast as many votes in the aggregate as shall equal the number of voting shares
so held by him, multiplied by the number of directors to be elected at such
election, and he may cast the whole


                                          3

<PAGE>

number of such votes for one or more candidates.  Directors shall not be elected
in any other manner, unless such cumulative voting be unanimously waived by all
stockholders present, in person or by proxy, and such waiver is permitted by
law.  No proxy shall be voted on after three years from its date, unless the
proxy provides for a longer period.

    Section 13.  Unless otherwise provided in the certificate of incorporation,
any action required to be taken at any annual or special meeting of stockholders
of the corporation, or any action which may be taken at any annual or special
meeting of such stockholders, may be taken without a meeting, without prior
notice and without a vote, if a consent in writing, setting forth the action so
taken, shall be signed by the holders of outstanding stock having not less than
the minimum number of votes that would be necessary to authorize or take such
action at a meeting at which all shares entitled to vote thereon were present
and voted.  Prompt notice of the taking of the corporate action without a
meeting by less than unanimous written consent shall be given to those
stockholders who have not consented in writing.

    Section 14.  The stockholders shall have the power by a vote of the holders
of shares at any regular meeting or special meeting expressly called for that
purpose, to remove any director from office with or without cause.  Such meeting
shall be held at any place prescribed by law or at any other place which may be
permissible under law, and which is designated in the notice of the special
meeting.  If less than the entire board is to be removed, no one of the
directors may be removed if the votes cast against his removal would be
sufficient to elect him if then cumulatively voted at an election of the entire
board of directors.



                                     ARTICLE III
                                      DIRECTORS

    Section 1.  Each director shall be a natural person who is at least twenty-
one years of age.  A director need not be a stockholder, a citizen of the United
States, or a resident of the State of Delaware unless required by law or the
Certificate of Incorporation.

    Section 2.  The number of directors which shall constitute the whole board
shall be not less than three (3) nor more than seven (7).  The first board shall
consist of five (5) directors.  Thereafter, within the limits above specified,
the number of directors shall be determined by resolution of the board of
directors or by a majority of the outstanding shares of the corporation.  The
directors shall be elected at the annual meeting of the stockholders, except as
provided in Section 3 of this Article, and each director elected shall hold
office until his successor is elected and qualified.  Directors need not be
stockholders.

    Section 3.  Any director may resign effective upon giving written notice to
the chairman of the board, the president, the secretary or the board of
directors of the corporation, unless the notice specifies a later time for
effectiveness of such resignation.  If a resignation of a director is


                                          4

<PAGE>

effective at a future time, a successor may be elected to take office when the
resignation becomes effective.

    Section 4.  Vacancies and newly created directorships resulting from any
increase in the authorized number of directors may be filled by a majority of
the directors then in office, though less than a quorum, or by a sole remaining
director, and the directors so chosen shall hold office until the next annual
election and until their successors are duly elected and shall qualify, unless
sooner displaced.  If there are no directors in office, then an election of
directors may be held in the manner provided by statute.  If, at the time of
filling any vacancy or any newly created directorship, the directors then in
office shall constitute less than a majority of the whole board (as constituted
immediately prior to any such increase), the Court of Chancery may, upon
application of any stockholder or stockholders holding at least ten percent of
the total number of the shares at the time outstanding having the right to vote
for such directors, summarily order an election to be held to fill any such
vacancies or newly created directorships, or to replace the directors chosen by
the directors then in office.

    Section 5.  The business of the corporation shall be managed by or under
the direction of its board of directors which may exercise all such powers of
the corporation and do all such lawful acts and things as are not by statute or
by the certificate of incorporation or by these bylaws directed or required to
be exercised or done by the stockholders.



                          MEETINGS OF THE BOARD OF DIRECTORS

    Section 6.  The board of directors of the corporation may hold meetings,
both regular and special, either within or without the State of Delaware.

    Section 7.  Immediately following each annual meeting of the stockholders,
the newly elected board of directors shall hold a regular meeting at the place
where said annual meeting has been held or at such other place as shall be fixed
by the board of directors.  No notice of such meeting shall be necessary to the
newly elected directors in order legally to constitute the meeting, provided a
quorum shall be present.  In the event such meeting is not held at the time and
place so fixed by the board of directors, the meeting may be held at such time
and place as shall be specified in a notice given as hereinafter provided for
special meetings of the board of directors, or as shall be specified in a
written waiver signed by all of the directors.

    Section 8.  Regular meetings of the board of directors may be held without
notice at such time and at such place as shall from time to time be determined
by the board.

    Section 9.  Special meetings of the board may be called by the president on
five (5) days' notice delivered by mail or 48 hours' notice delivered
personally, by telephone or by facsimile communication.  Special meetings shall
be called by the chairman of the board or president, or


                                          5

<PAGE>

by the president or secretary in like manner and in like notice on the written
request of any two directors.

    Section 10.  Notice of a meeting need not be given to any director who
signs a written waiver of notice, whether before or after the meeting, or who
attends the meeting without protesting, prior thereto or at its commencement,
the lack of notice to such director.  No director who so protests shall be
considered present at any such meeting.  The transactions of any meeting of the
board of directors, however called and noticed or wherever held, are as valid as
though had at a meeting duly held after regular call and notice if a quorum is
present, and if, either before or after the meeting, each of the directors not
present (including each director who protested lack of notice) signs a written
waiver of notice, a consent to holding the meeting or an approval of the minutes
thereof.  All such waivers, consents and approvals shall be filed with the
corporate records or made a part of the minutes of the meeting.

    Section 11.  At all meetings a majority of the board of directors shall
constitute a quorum for the transaction of business and the act of a majority of
the directors present at any meeting at which there is a quorum shall be the act
of the board of directors, except as may be otherwise specifically provided by
statute or by the certificate of incorporation.  A meeting at which a quorum is
initially present may continue to transact business notwithstanding the
withdrawal of directors, so long as any action taken is approved by at least a
majority of the required quorum for such meeting.  If a quorum shall not be
present at any meeting of the board of directors the directors present thereat
may adjourn the meeting from time to time, without notice other than
announcement at the meeting, until a quorum shall be present; provided, however,
if the meeting is adjourned for more than two days, at least two (2) days'
notice by mail or 24 hours' notice delivered personally or by telephone or
telegraph, stating the time and place at which the meeting will reconvene, shall
be given to each director who was not present at the time of the adjournment.

    Section 12.  Unless otherwise restricted by the certificate of
incorporation or these bylaws, any action required or permitted to be taken at
any meeting of the board of directors or of any committee thereof may be taken
without a meeting, if all members of the board or committee, as the case may be,
consent thereto in writing, and the writing or writings are filed with the
minutes of proceedings of the board or committee.

    Section 13.  Unless otherwise restricted by the certificate of
incorporation or these bylaws, members of the board of directors, or any
committee designated by the board of directors, may participate in a meeting of
the board of directors, or any committee, by means of conference telephone or
similar communications equipment by means of which all persons participating in
the meeting can hear each other, and such participation in a meeting shall
constitute presence in person at the meeting.

<PAGE>

                               COMMITTEES OF DIRECTORS

    Section 14.  The board of directors may, by resolution passed by a majority
of the whole board, designate one or more committees, each committee to consist
of one or more of the directors of the corporation.  The board may designate one
or more directors as alternate members of any committee, who may replace any
absent or disqualified member at any meeting of the committee.

    In the absence or disqualification of a member of a committee, the member
or members thereof present at any meeting and not disqualified from voting,
whether or not he or they constitute a quorum, may unanimously appoint another
member of the board of directors to act at the meeting in the place of any such
absent or disqualified member.

    Any such committee, to the extent provided in the resolution of the board
of directors, shall have and may exercise all the powers and authority of the
board of directors in the management of the business and affairs of the
corporation, and may authorize the seal of the corporation to be affixed to all
papers which may require it; but no such committee shall have the power or
authority in reference to amending the certificate of incorporation, (except
that a committee may, to the extent authorized in the resolution or resolutions
providing for the issuance of shares of stock adopted by the board of directors
as provided in Section 151(a) fix any of the preferences or rights of such
shares relating to dividends, redemption, dissolution, any distribution of
assets of the corporation or the conversion into, or the exchange of such shares
for, shares of any other class or classes or any other series of the same or any
other class or classes of stock of the corporation) adopting an agreement of
merger or consolidation, recommending to the stockholders the sale, lease or
exchange of all or substantially all of the corporation's property and assets,
recommending to the stockholders a dissolution of the corporation or a
revocation of a dissolution, or amending the bylaws of the corporation; and,
unless the resolution or the certificate of incorporation expressly so provide,
no such committee shall have the power or authority to declare a dividend or to
authorize the issuance of stock or to adopt a certificate of ownership and
merger.  Such committee or committees shall have such name or names as may be
determined from time to time by resolution adopted by the board of directors.

    Section 15.  Each committee shall keep regular minutes of its meetings and
report the same to the board of directors when required.

                              COMPENSATION OF DIRECTORS

    Section 16.  Unless otherwise restricted by the certificate of
incorporation or these bylaws, the board of directors shall have the authority
to fix the compensation of directors.  The directors may be paid their expenses,
if any, of attendance at each meeting of the board of directors and may be paid
a fixed sum for attendance at each meeting of the board of directors or a stated
salary as director.  No such payment shall preclude any director from serving
the corporation in any


                                          7

<PAGE>

other capacity and receiving compensation therefor.  Members of special or
standing committees may be allowed like compensation for attending committee
meetings.

    Section 1.  Whenever, under the provisions of the statutes or of the
certificate of incorporation or of these bylaws, notice is required to be given

corporate seal of the corporation and he, or an assistant secretary, shall have
authority to affix the same to any instrument requiring it and when so affixed,

corporation.

    Section 16.  If required by the board of directors, he shall give the
corporation a bond (which shall be renewed every six years) in such sum and with
such surety or sureties as shall be satisfactory to the board of directors for
the faithful performance of the duties of his office and for the restoration to
the corporation, in case of his death, resignation, retirement or removal from
office, of all books, papers, vouchers, money and other property of whatever
kind in his possession or under his control belonging to the corporation.

                                      ARTICLE VI
                               CERTIFICATES FOR SHARES

    Section 1.  The corporation shall not issue shares of stock except for
money paid, labor done or property actually received; provided, however, that
shares may be issued in consideration of valid bona fide antecedent debts.  No
note or obligation given by any stockholder, whether secured by deed of trust,
mortgage or otherwise shall be considered as payment of any part of any share or
shares.

    Section 2.       The certificates for shares of stock of the corporation
shall be numbered, shall be in such form as may be prescribed by the board of
directors in conformity with law, and shall be entered in the stock books of the
corporation or association to whom each certificate is issued.  Each certificate
shall have printed, typed or written thereon the name of the person, firm,
partnership, corporation or association to whom it is issued, and number of
shares represented thereby and shall be signed by the chairman of the board (if
any) or the president or a vice president, and the treasurer or an assistant
treasurer or the secretary or an assistant secretary of the corporation and
sealed with the seal of the corporation, which seal may be facsimile, engraved
or printed.  If the corporation has a registrar, a transfer agent, or a transfer
clerk who actually signs such certificates, the signature of any of the other
officers above mentioned may be facsimile, engraved or printed.  In case any
such officer who has signed or whose shall have ceased to be such officer before
such certificate is issued, such certificate may nevertheless be issued by the
corporation with the same effect as if such officer were an officer at the date
of its issue.


                                  LOST CERTIFICATES

    Section 3.  In case of the loss or destruction of any certificate for
shares of stock of the corporation, upon due proof of the registered owner
thereof or his representatives, by affidavit of such loss or otherwise, the
president and secretary may issue a duplicate certificate (plainly marked
"duplicate") in its place, upon the corporation being fully indemnified
therefor.  Either of such officer may request the posting of an indemnity bond
in favor of the corporation whenever and to the extent that they deem
appropriate as a precondition to the issuance of any duplicate certificate.


                                  TRANSFER OF STOCK

    Section 4.  Transfers of shares of stock shall be made on the stock record
or transfer books of the corporation only by the person named in the stock
certificate, or by his attorney lawfully constituted in writing, and upon
surrender of the certificate therefor.  The stock record book and other transfer
records shall be in the possession of the secretary (or other person appointed
and empowered by the board to do so) or of a transfer agent or clerk for the
corporation.  The


                                          12

<PAGE>

corporation, by resolution of the board, may from time to time appoint a
transfer agent, and, if desired, a registrar, under such arrangements and upon
such terms and conditions as the board deems advisable; but until and unless the
board appoints some other person, firm or corporation as its transfer agent (and
upon the revocation of any such appointment, thereafter until a new appointment
is similarly made) the secretary of the corporation (or other person appointed
and empowered by the board) shall be the transfer agent or clerk of the
corporation, without the necessity of any formal action of the board, and the
secretary or other person shall perform all of the duties thereof.


                                  FIXING RECORD DATE

    Section 5.  In order that the corporation may determine the stockholders
entitled to notice of or to vote at any meeting of stockholders or any
adjournment thereof, or to express consent to corporate action in writing
without a meeting, or entitled to receive payment of any dividend or other
distribution or allotment of any rights, or entitled to exercise any rights in
respect of any change, conversion or exchange of stock or for the purpose of any
other lawful action, the board of directors may fix, in advance, a record date,
which shall not be more than sixty nor less than ten days before the date of
such meeting, nor more than sixty days prior to any other action. A
determination of stockholders of record entitled to notice of or to vote at a
meeting of stockholders shall apply to any adjournment of the meeting: provided,
however, that the board of directors may fix a new record date for the adjourned
meeting.  If the board of directors does not set a record date for the
determination of the stockholders entitled to notice of, and to vote at, the
meeting, and any adjournment of the meeting, the record date shall be the date
that is twenty days previous to the meeting; except that, if prior to the
meeting written waivers of notice of the meeting are signed and delivered to the
corporation by all of the stockholders of record at the time the meeting is
convened, only the stockholders who are stockholders of record at the time the
meeting is convened shall be entitled to vote at the meeting, and any
adjournment of the meeting.


                              FRACTIONAL SHARE INTEREST

    Section 6.  The corporation may issue fractions of a share and it may issue
a certificate for a fractional share, or by action of the board of directors,
may issue in lieu thereof scrip or other evidence of ownership which shall
entitle the holder to receive a certificate for a full share upon the surrender
of such scrip or other evidence of ownership aggregating a full share.  A
certificate for a fractional share shall (but scrip or other evidence of
ownership shall not, unless otherwise provided by resolution of the board of
directors) entitle the holder to all of the rights of a stockholder, including
without limitation the right to exercise any voting right, or to receive
dividends thereon or to participate in any of the assets of the corporation in
the event of liquidation.  The board of directors may cause such scrip or
evidence of ownership (other than a certificate for a fractional share) to be
issued subject to the condition that the shares for which such scrip or evidence
of ownership is exchangeable may be sold by the corporation and the


                                          13

<PAGE>

proceeds thereof distributed to the holders of such scrip or evidence of
ownership, or subject to any other condition which the board of directors may
deem advisable.


                               REGISTERED STOCKHOLDERS

    Section 7.  The corporation shall be entitled to recognize the exclusive
right of a person registered on its books as the owner of shares to receive
dividends, and to vote as such owner, and to hold liable for calls and
assessments a person registered on its books as the owner of shares, and shall
not be bound to recognize any equitable or other claim to or interest in such
share or shares on the part of any other person, whether or not it shall have
express or other notice thereof, except as otherwise provided by the laws of
Delaware.


                                     ARTICLE VII
                                   INDEMNIFICATION

    Section 1.  Each person who is or was a director or officer of the
corporation or is or was serving at the request of the corporation as a director
or officer of another corporation (including the heirs, personal
representatives, or estate of such person) shall be indemnified by the
corporation as a matter of right to the full extent permitted or authorized by
the laws of the State of Delaware, as now in effect and as hereafter amended,
against any liability, judgment, fine, amount paid in settlement, cost and
expense (including attorneys' fees) asserted or threatened against and incurred
by such person (other than in an action by or in right of the corporation) in
his capacity as or arising out of his status as a director or officer of the
corporation or, if serving at the request of the corporation, as a director or
officer of another corporation, if he acted in good faith and in a manner he
reasonably believed to be in, or not opposed to, the best interests of the
corporation, and, with respect to any criminal action or proceeding, he had no
reason to believe his conduct was unlawful.  The termination of any action, suit
or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo
contendere or its equivalent, shall not, of itself, create a presumption that
the person did not act in good faith and in a manner which he reasonably
believed to be in, or not opposed to, the best interests of the corporation,
and, with respect to any criminal action or proceeding, he had no reason to
believe his conduct was unlawful.

    Section 2.  The corporation shall also indemnify any person who was or is a
party, or is threatened to be made a party to any threatened, pending or
completed action or suit by or in the right of the corporation to procure a
judgment in its favor by reason of the fact that he is nor was a director or
officer of the corporation or, if serving at the request of the corporation, as
a director or officer of another corporation, against expenses (including
attorneys' fees) actually and reasonably incurred by him in connection with the
defense or settlement of such action or suit, if he acted in good faith and in a
manner he reasonably believed to be in, or not opposed to, the best interests of
the corporation.  Notwithstanding the foregoing, no such indemnification shall
be


                                          14

<PAGE>

made in respect of any claim, issue or matter as to which such person shall have
been adjudged to be liable for negligence or misconduct in the performance of
his duty to the corporation, unless, and only to the extent that the court in
which such action or suit was brought shall determine upon application that,
despite the adjudication of liability, but in view of all the circumstances of
the case, such person is fairly and reasonably entitled to indemnity for such
expenses as the court shall deem proper.

    Section 3.  The indemnification provided by this Article shall not be
exclusive of any other rights to which those indemnified may be entitled under
any other by-law provision or under any agreement, vote or stockholders or
disinterested directors or otherwise, and shall not limit in any way right which
the corporation may have to make different or further indemnifications with
respect to the same or different persons or classes of persons.

    Section 4.  Any indemnification provided by this Article (unless ordered by
a Court) shall be made by the corporation only upon a determination that
indemnification of the director or officer is proper in the circumstances
because he has met the applicable standard of conduct set forth herein.  Such
determination shall be made: (1) by the board of directors upon a majority vote
of a quorum consisting of directors who were not parties to such action, suit or
proceeding; or (2) if such a quorum is not obtainable, or even if so obtainable,
a majority of directors who were not parties to such action, suit or proceeding
so directs, by independent legal counsel in a written opinion; or (3) by the
stockholders.

    Section 5.  Expenses incurred by an officer or director of the corporation
in defending a civil or criminal action, suit or proceeding may be paid by the
corporation in advance of the final disposition of such action, suit or
proceeding, as authorized in the manner set forth in the immediately preceding
paragraph, upon receipt of a written promise by or on behalf of the director or
officer to repay such amount in the event it shall ultimately be determined that
he is not entitled to be indemnified by the corporation under the provisions of
this Article.

    Section 6.  The corporation may purchase and maintain insurance on behalf
of any person who is or was a director or officer of the corporation or, if
serving at the request of the corporation, who is or was serving as a director
or officer of another corporation, against any liability asserted against him
and incurred by him in any such capacity, or arising out of his status as such,
whether or not the corporation would have the power to indemnify him against
such liability under the provisions of this Article.

    Section 7.  No person shall be liable to the corporation for any loss,
damage, liability or expense suffered by it on account of any action taken or
omitted to be taken by him as a director or officer of the corporation or of any
other corporation which he serves as a director or officer at the request of the
corporation, if such person (i) exercised the same degree of care and skill as a
prudent man would have exercised under the circumstances in the conduct of his
own affairs, or (ii) took or omitted to take such action in reliance upon advice
of counsel for the corporation, or of such other corporation, which he had no
reasonable grounds to disbelieve.


                                          15

<PAGE>

    Section 8.  To the extent that the foregoing provisions concerning
indemnification and liability conflict with any provisions of the Certificate of
Incorporation, the said Certificate shall control.


                                     ARTICLE VIII
                                  GENERAL PROVISIONS
                                      DIVIDENDS

    Section 1.  Dividends upon the capital stock of the corporation, subject to
the provisions of the certificate of incorporation, if any, may be declared by
the board of directors at any regular or special meeting, pursuant to law.
Dividends may be paid in cash, in property, or in shares of the capital stock,
subject to the provisions of the certificate of incorporation.

    Section 2.  Before payment of any dividend, there may be set aside out of
any funds of the corporation available for dividends such sum or sums as the
directors from time to time, in their absolute discretion, think proper as a
reserve or reserves to meet contingencies, or for equalizing dividends, or for
repairing or maintaining any property of the corporation, or for such other
purpose as the directors shall think conducive to the interest of the
corporation, and the directors may modify or abolish any such reserve in the
manner in which it was created.


                                EXECUTION OF CONTRACTS

    Section 3.  The board of directors, except as in these bylaws otherwise
provided, may authorize any officer or officers or agent or agents to enter into
any contract or execute any instrument in the name of and on behalf of the
corporation.  Such authority may be generally, or confined to specific
instances.  Unless so authorized by the board of directors, no officer, agent or
employee shall have any power or authority to bind the corporation by any
contract or engagement or to pledge its credit, or to render it liable for any
purpose or in any amount; provided, however, that nothing contained in this
section 3 shall be construed to prevent any officer of the corporation from
performing his regular duties in the ordinary course of business pursuant to the
authority granted to said officer by Article V of these Bylaws.

    Section 4.  All shares of any other corporation standing in the name of
this corporation shall be voted, represented, and all rights incidental thereto
exercised as directed by written consent or resolution of the board of directors
expressly referring thereto.  In general, such rights shall be delegated by the
board of directors, under express instructions from time to time as to such
exercise thereof, the president, or any vice president, and the secretary or any
assistant secretary of this corporation, or any other person expressly appointed
by the board of directors.  Such authority may be exercised by the designated
officers in person, or by any other person authorized so to do by proxy, or
power of attorney, duly executed by such officers.

                            TRANSFER AGENTS AND REGISTRARS

    Section 5.  The board of directors may appoint one or more transfer agents
or transfer clerks, and one or more registrars, who may be the same person, and

Articles of Incorporation, the board of directors is expressly empowered to

    Section 1.  These bylaws may be altered, amended or repealed or new bylaws
may be adopted by the stockholders or by the board of directors, when such power

<PAGE>

         SECTION 4.     EXERCISE.

         (a)  Each Warrant may be exercised by the Registered Holder thereof at
any time on or after the Initial Exercise Date, but not after the Warrant
Expiration Date, upon the terms and subject to the conditions set forth herein
and in the applicable Warrant Certificate.  A Warrant shall be deemed to have
been exercised immediately prior to the close of business on the Exercise Date
and the person entitled to receive the securities deliverable upon such exercise
shall be treated for all purposes as the holder of those securities upon the
exercise of the Warrant as of the close of business on the Exercise Date.  As
soon as practicable on or after the Exercise Date, the Warrant Agent shall
deposit the proceeds received from the exercise of a Warrant and shall notify
the Company in writing of the exercise of the Warrants.  Promptly following, and
in any event within five days after the date of such notice from the Warrant
Agent, the Warrant Agent, on behalf of the Company, shall cause to be issued and
delivered by the Transfer Agent, to the person or persons entitled to receive
the same, a certificate or certificates for the securities deliverable upon such
exercise, (plus a Warrant Certificate for any remaining unexercised Warrants of
the Registered Holder) unless prior to the date of issuance of such certificates
the Company shall instruct the Warrant Agent to refrain from causing such
issuance of certificates pending clearance of checks received in payment of the
Purchase Price pursuant to such Warrants.  Notwithstanding the foregoing, in the
case of payment made in the form of a check drawn on an account of Blair or such
other investment banks and brokerage houses as the Company shall approve in
writing to the Warrant Agent, certificates shall immediately be issued without
prior notice to the Company or any delay.  Upon the exercise of any Warrant and
clearance of the funds received, the Warrant Agent shall promptly remit the
payment received for the Warrant (the "Warrant Proceeds") to the Company or as
the Company may direct in writing, subject to the provisions of Sections 4(b)
and 4(c) hereof.

         (b)  If, at the Exercise Date in respect of the exercise of any
Warrant after      , 1997, (i) the market price of the Company's Class A Common
Stock is greater than the then Purchase Price of the Warrant, (ii) the exercise
of the Warrant was solicited by a member of the National Association of
Securities Dealers, Inc.  ("NASD") as designated in writing on the Warrant
Certificate Subscription Form, (iii) the Warrant was not held in a discretionary
account, (iv) disclosure of compensation arrangements was made both at the time
of the original offering and at the time of exercise; and (v) the solicitation
of the exercise of the Warrant was not in violation of Rule 10b-6 (as such rule
or any successor rule may be in effect as of such time of exercise) promulgated
under the Securities Exchange Act of 1934, then the Warrant Agent,
simultaneously with the distribution of the Warrant Proceeds to the Company
shall, on behalf of the Company, pay from the Warrant Proceeds, a fee of 5% (the
"Blair Fee") of the Purchase Price to Blair (of which a portion may be reallowed
by Blair to the dealer who solicited the exercise, which may also be Blair or
D.H.  Blair & Co., Inc.).  In the event the Blair Fee is not received within
five days of the date on which the Company receives Warrant Proceeds, then the
Blair Fee shall begin accruing interest at an annual rate of prime plus four
(4)%, payable by the Company to Blair at the time Blair receives the Blair Fee.
Within five days after exercise the Warrant Agent shall send to Blair a copy of
the reverse side of each Warrant exercised.  Blair shall reimburse the Warrant
Agent, upon request, for its reasonable expenses relating to


                                         -5-

<PAGE>

compliance with this section 4(b).  In addition, Blair and the Company may at
any time during business hours, examine the records of the Warrant Agent,
including its ledger of original Warrant Certificates returned to the Warrant
Agent upon exercise of Warrants.  The provisions of this paragraph may not be
modified, amended or deleted without the prior written consent of Blair.

         (c)  In order to enforce the provisions of Section 4(b) above, in the
event there is any dispute or question as to the amount or payment of the Blair
Fee, the Warrant Agent is hereby expressly authorized to withhold payment to the
Company of the Warrant Proceeds unless and until the Company establishes an
escrow account for the purpose of depositing the entire amount of the Blair Fee,
which amount will be deducted from the net Warrant Proceeds to be paid to the
Company.  The funds placed in the escrow account may not be released to the
Company without a written agreement from Blair that the required Blair Fee has
been received by Blair.

         SECTION 5.     RESERVATION OF SHARES; LISTING; PAYMENT OF TAXES; ETC.

         (a)  The Company covenants that it will at all times reserve and keep
available out of its authorized Class A Common Stock, solely for the purpose of
issue upon exercise of Warrants, such number of shares of Class A Common Stock
as shall then be issuable upon the exercise of all outstanding Warrants.  The
Company covenants that all shares of Class A Common Stock which shall be
issuable upon exercise of the Warrants shall, at the time of delivery, be duly
and validly issued, fully paid, nonassessable and free from all taxes, liens and
charges with respect to the issue thereof, (other than those which the Company
shall promptly pay or discharge) and that upon issuance such shares shall be
listed on each national securities exchange, on which the other shares of
outstanding Class A Common Stock of the Company are then listed or shall be
eligible for inclusion in the Nasdaq National Market or the Nasdaq SmallCap
Market if the other shares of outstanding Class A Common Stock of the Company
are so included.

         (b)  The Company covenants that if any securities to be reserved for
the purpose of exercise of Warrants hereunder require registration with, or
approval of, any governmental authority under any federal securities law before
such securities may be validly issued or delivered upon such exercise, then the
Company will in good faith and as expeditiously as reasonably possible, endeavor
to secure such registration or approval.  The Company will use reasonable
efforts to obtain appropriate approvals or registrations under state "blue sky"
securities laws.  With respect to any such securities, however, Warrants may not
be exercised by, or shares of Class A Common Stock issued to, any Registered
Holder in any state in which such exercise would be unlawful.

         (c)  The Company shall pay all documentary, stamp or similar taxes and
other governmental charges that may be imposed with respect to the issuance of
Warrants, or the issuance or delivery of any shares or Class B Warrants upon
exercise of the Class A Warrants, or the issuance or delivery of any shares upon
exercise of the Class B Warrants; provided, however,


                                         -6-

<PAGE>

that if the shares of Class A Common Stock or Class B Warrants, as the case may
be, are to be delivered in a name other than the name of the Registered Holder
of the Warrant Certificate representing any Warrant being exercised, then no
such delivery shall be made unless the person requesting the same has paid to
the Warrant Agent the amount of transfer taxes or charges incident thereto, if
any.

         (d)  The Warrant Agent is hereby irrevocably authorized to requisition
the Company's Transfer Agent from time to time for certificates representing
shares of Class A Common Stock issuable upon exercise of the Warrants, and the
Company will authorize the Transfer Agent to comply with all such proper
requisitions.  The Company will file with the Warrant Agent a statement setting
forth the name and address of the Transfer Agent of the Company for shares of
Class A Common Stock issuable upon exercise of the Warrants.

         SECTION 6.     EXCHANGE AND REGISTRATION OF TRANSFER.

         (a)  Warrant Certificates may be exchanged for other Warrant
Certificates representing an equal aggregate number of Warrants of the same
class or may be transferred in whole or in part.  Warrant Certificates to be
exchanged shall be surrendered to the Warrant Agent at its Corporate Office, and
upon satisfaction of the terms and provisions hereof, the Company shall execute
and the Warrant Agent shall countersign, issue and deliver in exchange therefor
the Warrant Certificate or Certificates which the Registered Holder making the
exchange shall be entitled to receive.

         (b)  The Warrant Agent shall keep at its office books in which,
subject to such reasonable regulations as it may prescribe, it shall register
Warrant Certificates and the transfer thereof in accordance with its regular
practice.  Upon due presentment for registration of transfer of any Warrant
Certificate at such office, the Company shall execute and the Warrant Agent
shall issue and deliver to the transferee or transferees a new Warrant
Certificate or Certificates representing an equal aggregate number of Warrants.

         (c)  With respect to all Warrant Certificates presented for
registration or transfer, or for exchange or exercise, the subscription form on
the reverse thereof shall be duly endorsed, or be accompanied by a written
instrument or instruments of transfer and subscription, in form satisfactory to
the Company and the Warrant Agent, duly executed by the Registered Holder or his
attorney-in-fact duly authorized in writing.

         (d)  A service charge may be imposed by the Warrant Agent for any
exchange or registration of transfer of Warrant Certificates.  In addition, the
Company may require payment by such holder of a sum sufficient to cover any tax
or other governmental charge that may be imposed in connection therewith.

         (e)  All Warrant Certificates surrendered for exercise or for exchange
in case of mutilated Warrant Certificates shall be promptly cancelled by the
Warrant Agent and thereafter retained by the Warrant Agent until termination of
this Agreement or resignation as


                                         -7-

<PAGE>

Warrant Agent, or, with the prior written consent of Blair, disposed of or
destroyed, at the direction of the Company.

         (f)  Prior to due presentment for registration of transfer thereof,
the Company and the Warrant Agent may deem and treat the Registered Holder of
any Warrant Certificate as the absolute owner thereof and of each Warrant
represented thereby (notwithstanding any notations of ownership or writing
thereon made by anyone other than a duly authorized officer of the Company or
the Warrant Agent) for all purposes and shall not be affected by any notice to
the contrary.  The Warrants, which are being publicly offered in Units with
shares of Class A Common Stock pursuant to the Underwriting Agreement, will be
immediately detachable from the Class A Common Stock and transferable separately
therefrom.

         SECTION 7.     LOSS OR MUTILATION.  Upon receipt by the Company and
the Warrant Agent of evidence satisfactory to them of the ownership of and loss,
theft, destruction or mutilation of any Warrant Certificate and (in case of
loss, theft or destruction) of indemnity satisfactory to them, and (in the case
of mutilation) upon surrender and cancellation thereof, the Company shall
execute and the Warrant Agent shall ( in the absence of notice to the Company
and/or Warrant Agent that the Warrant Certificate has been acquired by a bona
fide purchaser) countersign and deliver to the Registered Holder in lieu thereof
a new Warrant Certificate of like tenor representing an equal aggregate number
of Class A Warrants or Class B Warrants.  Applicants for a substitute Warrant
Certificate shall comply with such other reasonable regulations and pay such
other reasonable charges as the Warrant Agent may prescribe.

         SECTION 8.     REDEMPTION.

         (a)  Subject to the provisions of paragraph 2(g) hereof, on not less
than thirty (30) days notice given at any time after         , 1997 (the
"Redemption Notice"), to Registered Holders of the Warrants being redeemed, the
Warrants may be redeemed, at the option of the Company, at a redemption price of
$0.05 per Warrant, provided the Market Price of the Class A Common Stock
receivable upon exercise of such Warrants shall exceed $12.00 with respect to
the Class A Warrants and $15.00 with respect to the Class B Warrants (the
"Target Prices"), subject to adjustment as set forth in Section 8(f), below.
Market Price shall mean (i) the average closing bid price of the Class A Common
Stock, for thirty (30) consecutive business days ending on the Calculation Date
as reported by Nasdaq, if the Class A Common Stock is traded on the Nasdaq
SmallCap Market, or (ii) the average last reported sale price of the Class A
Common Stock, for thirty (30) consecutive business days ending on the
Calculation Date, as reported by the primary exchange on which the Class A
Common Stock is traded, if the Class A Common Stock is traded on a national
securities exchange, or by Nasdaq, if the Class A Common Stock is traded on the
Nasdaq National Market.  All Warrants of a class must be redeemed if any of that
class are redeemed, provided that the Warrants underlying the Unit Purchase
Option may only be redeemed in compliance with and subject to the terms and
conditions of the Unit Purchase Option.  For purposes of this Section 8, the
Calculation Date shall mean a date within 15 days of the mailing of the
Redemption Notice.  The date fixed for redemption of the Warrants is referred


                                         -8-

<PAGE>

to herein as the "Redemption Date".  The Class B Warrant Redemption Date may not
be earlier than thirty-one (31) days after the Class A Warrant Redemption Date.

         (b)  If the conditions set forth in Section 8(a) are met, and the
Company desires to exercise its right to redeem the Warrants, it shall request
Blair to mail a Redemption Notice to each of the Registered Holders of the
Warrants to be redeemed, first class, postage prepaid, not later than the
thirtieth day before the date fixed for redemption, at their last address as
shall appear on the records maintained pursuant to Section 6(b).  Any notice
mailed in the manner provided herein shall be conclusively presumed to have been
duly given whether or not the Registered Holder receives such notice.

         (c)  The Redemption Notice shall specify (i) the redemption price,
(ii) the Redemption Date, (iii) the place where the Warrant Certificates shall
be delivered and the redemption price paid, (iv) that Blair will assist each
Registered Holder of a Warrant in connection with the exercise thereof and (v)
that the right to exercise the Warrant shall terminate at 5:00 P.M.  (New York
time) on the business day immediately preceding the Redemption Date.  No failure
to mail such notice nor any defect therein or in the mailing thereof shall
affect the validity of the proceedings for such redemption except as to a
Registered Holder (a) to whom notice was not mailed or (b) whose notice was
defective.  An affidavit of the Warrant Agent or of the Secretary or an
Assistant Secretary of Blair or the Company that notice of redemption has been
mailed shall, in the absence of fraud, be prima facie evidence of the facts
stated therein.

         (d)  Any right to exercise a Warrant shall terminate at 5:00 P.M.
(New York time) on the business day immediately preceding the Redemption Date.
On and after the Redemption Date, Registered Holders of the Warrants shall have
no further rights except to receive, upon surrender of the Warrant, the
Redemption Price.

         (e)  From and after the Redemption Date, the Company shall, at the
place specified in the Redemption Notice, upon presentation and surrender to the
Company by or on behalf of the Registered Holder thereof of one or more Warrant
Certificates evidencing Warrants to be redeemed, deliver or cause to be
delivered to or upon the written order of such Registered Holder a sum in cash
equal to the Redemption Price of each such Warrant.  From and after the
Redemption Date and upon the deposit or setting aside by the Company of a sum
sufficient to redeem all the Warrants called for redemption, such Warrants shall
expire and become void and all rights hereunder and under the Warrant
Certificates, except the right to receive payment of the Redemption Price, shall
cease.

         (f)  If the shares of the Company's Common Stock are subdivided or
combined into a greater or smaller number of shares of Common Stock, the Target
Prices shall be proportionally adjusted by the ratio which the total number of
shares of Common Stock outstanding immediately prior to such event bears to the
total number of shares of Common Stock to be outstanding immediately after such
event.


                                         -9-

<PAGE>

         SECTION 9.     ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF SHARES OF
                        CLASS A COMMON STOCK OR WARRANTS.

         (a)  (1)  Subject to the exceptions referred to in Section 9(g) below,
in the event the Company shall, at any time or from time to time after the date
hereof, sell any shares of Common Stock for a consideration per share less than
the Market Price of the Class A Common Stock (as defined in Section 8, except
that for purposes of Section 9, the Calculation Date shall mean the date of the
sale or other transaction referred to in this Section 9) on the date of the sale
(any such sale being herein called a "Change of Shares"), then, and thereafter
upon each further Change of Shares, the Purchase Price in effect immediately
prior to such Change of Shares shall be changed to a price (including any
applicable fraction of a cent) determined by multiplying the Purchase Price in
effect immediately prior thereto by a fraction, the numerator of which shall be
the sum of the number of shares of Common Stock outstanding immediately prior to
the issuance of such additional shares and the number of shares of Common Stock
which the aggregate consideration received (determined as provided in subsection
9(f)(F) below) for the issuance of such additional shares would purchase at the
Market Price and the denominator of which shall be the sum of the number of
shares of Common Stock outstanding immediately after the issuance of such
additional shares.  Such adjustment shall be made successively whenever such an
issuance is made.

              Upon each adjustment of the Purchase Price pursuant to this
Section 9, the total number of shares of Class A Common Stock purchasable upon
the exercise of each Class A Warrant or each Class B Warrant, as applicable,
shall (subject to the provisions contained in Section 9(a)(2) hereof) be such
number of shares (calculated to the nearest tenth) purchasable at the Purchase
Price in effect immediately prior to such adjustment multiplied by a fraction,
the numerator of which shall be the Purchase Price in effect immediately prior
to such adjustment and the denominator of which shall be the Purchase Price in
effect immediately after such adjustment.

              (2)  The Company may elect, upon any adjustment of the Purchase
Price hereunder, to adjust the number of Class A Warrants or Class B Warrants
outstanding, in lieu of the adjustment in the number of shares of Class A Common
Stock purchasable upon the exercise of each Warrant as hereinabove provided, so
that each Class A Warrant outstanding after such adjustment shall represent the
right to purchase one share of Class A Common Stock and one Class B Warrant, and
each Class B Warrant outstanding after such adjustment shall represent the right
to purchase one share of Class A Common Stock.  Each Warrant held of record
prior to such adjustment of the number of Warrants shall become that number of
Warrants (calculated to the nearest tenth) determined by multiplying the number
one by a fraction, the numerator of which shall be the Purchase Price in effect
immediately prior to such adjustment and the denominator of which shall be the
Purchase Price in effect immediately after such adjustment.

         (b)  In case the Company shall (i) declare and pay a dividend or make
a distribution on its outstanding shares of Common Stock in shares of Common
Stock,


                                         -10-

<PAGE>

(ii) subdivide or reclassify its outstanding shares of Common Stock into a
greater number of shares, or (iii) combine or reclassify its outstanding shares
of Common Stock into a smaller number of shares, the Purchase Price in effect at
the time of the record date for such dividend or distribution or of the
effective date of such subdivision, combination or reclassification shall be
adjusted so that it shall equal the price determined by multiplying the Purchase
Price by a fraction, the numerator of which shall be the number of shares of
Common Stock outstanding immediately prior to such action, and the denominator
of which shall be the number of shares of Common Stock outstanding after giving
effect to such action.  Such adjustment shall be made successively whenever any
event listed above shall occur.  Whenever the Purchase Price is adjusted
pursuant to this Subsection (b), the number of Class A Warrants or Class B
Warrants outstanding shall be adjusted so that each Class A Warrant outstanding
after such adjustment shall represent the right to purchase one share of Class A
Common Stock and one Class B Warrant, and each Class B Warrant outstanding after
such adjustment shall represent the right to purchase one share of Class A
Common Stock.  Each Warrant held of record prior to such adjustment of the
number of Warrants shall become that number of Warrants (calculated to the
nearest tenth) determined by multiplying the number one by a fraction, the
numerator of which shall be the Purchase Price in effect immediately prior to
such adjustment and the denominator of which shall be the Purchase Price in
effect immediately after such adjustment.

         (c)  In case of any reclassification, capital reorganization or other
change of outstanding shares of Common Stock, or in case of any consolidation or
merger of the Company with or into another corporation (other than a
consolidation or merger in which the Company is the continuing corporation and
which does not result in any reclassification, capital reorganization or other
change of outstanding shares of Common Stock), or in case of any sale or
conveyance to another corporation of the property of the Company as, or
substantially as, an entirety (other than a sale/leaseback, mortgage or other
financing transaction), the Company shall cause effective provision to be made
so that each holder of a Warrant then outstanding shall have the right
thereafter, by exercising such Warrant, to purchase the kind and number of
shares of stock or other securities or property (including cash) receivable upon
such reclassification, capital reorganization or other change, consolidation,
merger, sale or conveyance by a holder of the number of shares of Common Stock
that might have been purchased upon exercise of such Warrant immediately prior
to such reclassification, capital reorganization or other change, consolidation,
merger, sale or conveyance.  Any such provision shall include provision for
adjustments that shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Section 9.  The Company shall not effect any
such consolidation, merger or sale unless prior to or simultaneously with the
consummation thereof the successor (if other than the Company) resulting from
such consolidation or merger or the corporation purchasing assets or other
appropriate corporation or entity shall assume, by written instrument executed
and delivered to the Warrant Agent, the obligation to deliver to the holder of
each Warrant such shares of stock, securities or assets as, in accordance with
the foregoing provisions, such holders may be entitled to purchase and the other
obligations of the Company under this Agreement.  The foregoing provisions shall
similarly apply to successive reclassifications, capital reorganizations and
other changes of outstanding shares of Common Stock and to successive
consolidations, mergers, sales or conveyances.

         (d)  Irrespective of any adjustments or changes in the Purchase Price
or the number of shares of Class A Common Stock purchasable upon exercise of the
Warrants, the Warrant Certificates theretofore and thereafter issued shall,
unless the Company shall exercise its option to issue new Warrant Certificates
pursuant to Section 2(f) hereof, continue to express the Purchase Price per
share, the number of shares purchasable thereunder and the Redemption Price
therefor as the Purchase Price per share, and the number of shares purchasable
and the Redemption Price therefor were expressed in the Warrant Certificates
when the same were originally issued.

         (e)  After each adjustment of the Purchase Price pursuant to this
Section 9, the Company will promptly prepare a certificate signed by the
Chairman or President, and by the Treasurer or an Assistant Treasurer or the
Secretary or an Assistant Secretary, of the Company setting forth:  (i) the
Purchase Price as so adjusted, (ii) the number of shares of Class A Common Stock
purchasable upon exercise of each Warrant after such adjustment and, if the
Company shall have elected to adjust the number of Warrants, the number of
Warrants to which the Registered Holder of each Warrant shall then be entitled,
and the adjustment in Redemption Price resulting therefrom, and (iii) a brief
statement of the facts accounting for such adjustment.  The Company will
promptly file such certificate with the Warrant Agent and cause a brief summary
thereof to be sent by ordinary first class mail to Blair and to each Registered
Holder of Warrants at his last address as it shall appear on the registry books
of the Warrant Agent.  No failure to mail such notice nor any defect therein or
in the mailing thereof shall affect the validity thereof except as to the holder
to whom the Company failed to mail such notice, or except as to the holder whose
notice was defective.  The affidavit of an officer of the Warrant Agent or the
Secretary or an Assistant Secretary of the Company that such notice has been
mailed shall, in the absence of fraud, be prima facie evidence of the facts
stated therein.

         (f)  For purposes of Section 9(a) and 9(b) hereof, the following
provisions (A) to (F) shall also be applicable:

              (A)  The number of shares of Common Stock outstanding at any
         given time shall include shares of Common Stock owned or held by or
         for the account of the Company and the sale or issuance of such
         treasury shares or the distribution of any such treasury shares shall
         not be considered a Change of Shares for purposes of said sections.

              (B)  No adjustment of the Purchase Price shall be made unless
         such adjustment would require an increase or decrease of at least $.10
         in the Purchase Price; provided that any adjustments which by reason
         of this clause (B) are not required to be made shall be carried
         forward and shall be made at the time of and together with the next
         subsequent adjustment which, together with any adjustment(s) so
         carried forward, shall require an increase or decrease of at least
         $.10 in the Purchase Price then in effect hereunder.

              (C)  In case of (1) the sale by the Company for cash (or as a
         component of a unit being sold for cash) of any rights or warrants to
         subscribe for or purchase, or any options for the purchase of, Common
         Stock or any securities convertible into or exchangeable for Common
         Stock without the payment of any further consideration other than
         cash, if any (such securities convertible, exercisable or exchangeable
         into Common Stock being herein called "Convertible Securities"), or
         (2) the issuance by the Company, without the receipt by the Company of
         any consideration therefor, of any rights or warrants to subscribe for
         or purchase, or any options for the purchase of, Common Stock or
         Convertible Securities, in each case, if (and only if) the
         consideration payable to the Company upon the exercise of such rights,
         warrants or options shall consist of cash, whether or not such rights,
         warrants or options, or the right to convert or exchange such
         Convertible Securities, are immediately exercisable, and the price per
         share for which Common Stock is issuable upon the exercise of such
         rights, warrants or options or upon the conversion or exchange of such
         Convertible Securities (determined by dividing (x) the minimum
         aggregate consideration payable to the Company upon the exercise of
         such rights, warrants or options, plus the consideration, if any,
         received by the Company for the issuance or sale of such rights,
         warrants or options, plus, in the case of such Convertible Securities,
         the minimum aggregate amount of additional consideration, other than
         such Convertible Securities, payable upon the conversion or exchange
         thereof, by (y) the total maximum number of shares of Common Stock
         issuable upon the exercise of such rights, warrants or options or upon
         the conversion or exchange of such Convertible Securities issuable
         upon the exercise of such rights, warrants or options) is less than
         the Market Price of the Class A Common Stock on the date of the
         issuance or sale of such rights, warrants or options, then the total
         maximum number of shares of Common Stock issuable upon the exercise of
         such rights, warrants or options or upon the conversion or exchange of
         such Convertible Securities (as of the date of the issuance or sale of
         such rights, warrants or options) shall be deemed to be outstanding
         shares of Common Stock for purposes of Sections 9(a) and 9(b) hereof
         and shall be deemed to have been sold for cash in an amount equal to
         such price per share.

              (D)  In case of the sale by the Company for cash of any
         Convertible Securities, whether or not the right of conversion or
         exchange thereunder is immediately exercisable, and the price per
         share for which Common Stock is issuable upon the conversion or
         exchange of such Convertible Securities (determined by dividing (x)
         the total amount of consideration received by the Company for the sale
         of such Convertible Securities, plus the minimum aggregate amount of
         additional consideration, if any, other than such Convertible
         Securities, payable upon the conversion or exchange thereof, by (y)
         the total maximum number of shares of Common Stock issuable upon the
         conversion or exchange of such Convertible Securities) is less than
         the Market Price of the Class A Common Stock on the date of the sale
         of such Convertible Securities, then the total


                                         -13-

<PAGE>

         maximum number of shares of Common Stock issuable upon the conversion
         or exchange of such Convertible Securities (as of the date of the sale
         of such Convertible Securities) shall be deemed to be outstanding
         shares of Common Stock for purposes of Sections 9(a) and 9(b) hereof
         and shall be deemed to have been sold for cash in an amount equal to
         such price per share.

              (E)  In case the Company shall modify the rights of conversion,
         exchange or exercise of any of the securities referred to in (C) or
         (D) above or any other securities of the Company convertible,
         exchangeable or exercisable for shares of Common Stock, for any reason
         other than an event that would require adjustment to prevent dilution,
         so that the consideration per share received by the Company after such
         modification is less than the Market Price on the date prior to such
         modification, the Purchase Price to be in effect after such
         modification shall be determined by multiplying the Purchase Price in
         effect immediately prior to such event by a fraction, of which the
         numerator shall be the number of shares of Common Stock outstanding on
         the date prior to the modification plus the number of shares of Common
         Stock which the aggregate consideration receivable by the Company for
         the securities affected by the modification would purchase at the
         Market Price and of which the denominator shall be the number of
         shares of Common Stock outstanding on such date plus the number of
         shares of Common Stock to be issued upon conversion, exchange or
         exercise of the modified securities at the modified rate.  Such
         adjustment shall become effective as of the date upon which such
         modification shall take effect.  On the expiration of any such right,
         warrant or option or the termination of any such right to convert or
         exchange any such Convertible Securities referred to in Paragraph (C)
         or (D) above, the Purchase Price then in effect hereunder shall
         forthwith be readjusted to such Purchase Price as would have obtained
         (a) had the adjustments made upon the issuance or sale of such rights,
         warrants, options or Convertible Securities been made upon the basis
         of the issuance of only the number of shares of Common Stock
         theretofore actually delivered (and the total consideration received
         therefor) upon the exercise of such rights, warrants or options or
         upon the conversion or exchange of such Convertible Securities and (b)
         had adjustments been made on the basis of the Purchase Price as
         adjusted under clause (a) for all transactions (which would have
         affected such adjusted Purchase Price) made after the issuance or sale
         of such rights, warrants, options or Convertible Securities.

              (F)  In case of the sale for cash of any shares of Common Stock,
         any Convertible Securities, any rights or warrants to subscribe for or
         purchase, or any options for the purchase of, Common Stock or
         Convertible Securities, the consideration received by the Company
         therefore shall be deemed to be the gross sales price therefor without
         deducting therefrom any expense paid or incurred by the Company or any
         underwriting discounts or commissions or concessions paid or allowed
         by the Company in connection therewith.

         (g)  No adjustment to the Purchase Price of the Warrants or to the
number of shares of Common Stock purchasable upon the exercise of each Warrant
will be made, however,

              (i)    upon the exercise of any of the options presently
         outstanding under the Company's Stock Option Plan (the "Plan") for
         officers, directors and certain other key personnel of the Company; or

              (ii)   upon the issuance or exercise of any other securities
         which may hereafter be granted or exercised under the Plan or under
         any other employee benefit plan of the Company; or

              (iii)  upon the sale or exercise of the Warrants, including
         without limitation the sale or exercise of any of the Warrants
         comprising the Unit Purchase Option or upon the sale or exercise of
         the Unit Purchase Option; or

              (iv)   upon the sale of any shares of Common Stock or Convertible
         Securities in a firm commitment underwritten public offering,
         including, without limitation, shares sold upon the exercise of any
         overallotment option granted to the underwriters in connection with
         such offering; or

              (v)    upon the issuance or sale of Common Stock or Convertible
         Securities upon the exercise of any rights or warrants to subscribe
         for or purchase, or any options for the purchase of, Common Stock or
         Convertible Securities, whether or not such rights, warrants or
         options were outstanding on the date of the original sale of the
         Warrants or were thereafter issued or sold; or

              (vi)   upon the issuance or sale of Common Stock upon conversion
         or exchange of any Convertible Securities, whether or not any
         adjustment in the Purchase Price was made or required to be made upon
         the issuance or sale of such Convertible Securities and whether or not
         such Convertible Securities were outstanding on the date of the
         original sale of the Warrants or were thereafter issued or sold.

         (h)  As used in this Section 9, the term "Common Stock" shall mean and
include the Company's Class A Common Stock authorized on the date of the
original issue of the Units and shall also include any capital stock of any
class of the Company thereafter authorized which shall not be limited to a fixed
sum or percentage in respect of the rights of the holders thereof to participate
in dividends and in the distribution of assets upon the voluntary liquidation,
dissolution or winding up of the Company; provided, however, that the shares
issuable upon exercise of the Warrants shall include only shares of such class
designated in the Company's Certificate of Incorporation as Class A Common Stock
on the date of the original issue of the Units or (i), in the case of any
reclassification, change, consolidation, merger, sale or conveyance of the
character referred to in Section 9(c) hereof, the stock, securities or property
provided for in such section or (ii), in the case of any reclassification or
change in the outstanding shares of


                                         -15-

<PAGE>

Class A Common Stock issuable upon exercise of the Warrants as a result of a
subdivision or combination or consisting of a change in par value, or from par
value to no par value, or from no par value to par value, such shares of Common
Stock as so reclassified or changed.

         (i)  Any determination as to whether an adjustment in the Purchase
Price in effect hereunder is required pursuant to Section 9, or as to the amount
of any such adjustment, if required, shall be binding upon the holders of the
Warrants and the Company if made in good faith by the Board of Directors of the
Company.

         (j)  If and whenever the Company shall grant to the holders of Common
Stock, as such, rights or warrants to subscribe for or to purchase, or any
options for the purchase of, Common Stock or securities convertible into or
exchangeable for or carrying a right, warrant or option to purchase Common
Stock, the Company shall concurrently therewith grant to each Registered Holder
as of the record date for such transaction of the Warrants then outstanding, the
rights, warrants or options to which each Registered Holder would have been
entitled if, on the record date used to determine the stockholders entitled to
the rights, warrants or options being granted by the Company, the Registered
Holder were the holder of record of the number of whole shares of Class A Common
Stock then issuable upon exercise (assuming, for purposes of this Section 9(j),
that exercise of Warrants is permissible during periods prior to the Initial
Warrant Exercise Date) of his Warrants.  Such grant by the Company to the
holders of the Warrants shall be in lieu of any adjustment which otherwise might
be called for pursuant to this Section 9.

         SECTION 10.    FRACTIONAL WARRANTS AND FRACTIONAL SHARES.

         (a)  If the number of shares of Class A Common Stock purchasable upon
the exercise of each Warrant is adjusted pursuant to Section 9 hereof, the
Company nevertheless shall not be required to issue fractions of shares, upon
exercise of the Warrants or otherwise, or to distribute certificates that
evidence fractional shares.  With respect to any fraction of a share called for
upon the exercise of any Warrant, the Company shall pay to the Holder an amount
in cash equal to such fraction multiplied by the current market value of such
fractional share, determined as follows:

              (1)  If the Class A Common Stock is listed on a national
         securities exchange or admitted to unlisted trading privileges on such
         exchange or is traded on the Nasdaq National Market, the current
         market value shall be the last reported sale price of the Class A
         Common Stock on such exchange or market on the last business day prior
         to the date of exercise of this Warrant or if no such sale is made on
         such day, the average of the closing bid and asked prices for such day
         on such exchange or market; or

              (2)  If the Class A Common Stock is not listed or admitted to
         unlisted trading privileges on a national securities exchange or is
         not traded on the Nasdaq National Market, the current market value
         shall be the mean of the last reported


                                         -16-

<PAGE>

         bid and asked prices reported by the Nasdaq SmallCap Market or, if not
         traded thereon, by the National Quotation Bureau, Inc.  on the last
         business day prior to the date of the exercise of this Warrant; or

              (3)  If the Class A Common Stock is not so listed or admitted to
         unlisted trading privileges and bid and asked prices are not so
         reported, the current market value shall be an amount determined in
         such reasonable manner as may be prescribed by the Board of Directors
         of the Company.

         SECTION 11.    WARRANT HOLDERS NOT DEEMED STOCKHOLDERS.  No holder of
Warrants shall, as such, be entitled to vote or to receive dividends or be
deemed the holder of Class A Common Stock that may at any time be issuable upon
exercise of such Warrants for any purpose whatsoever, nor shall anything
contained herein be construed to confer upon the holder of Warrants, as such,
any of the rights of a stockholder of the Company or any right to vote for the
election of directors or upon any matter submitted to stockholders at any
meeting thereof, or to give or withhold consent to any corporate action (whether
upon any recapitalization, issue or reclassification of stock, change of par
value or change of stock to no par value, consolidation, merger or conveyance or
otherwise), or to receive notice of meetings, or to receive dividends or
subscription rights, until such holder shall have exercised such Warrants and
been issued shares of Common Stock in accordance with the provisions hereof.

         SECTION 12.    RIGHTS OF ACTION.  All rights of action with respect to
this Agreement are vested in the respective Registered Holders of the Warrants,
and any Registered Holder of a Warrant, without consent of the Warrant Agent or
of the holder of any other Warrant, may, in his own behalf and for his own
benefit, enforce against the Company his right to exercise his Warrants for the
purchase of shares of Common Stock in the manner provided in the Warrant
Certificate and this Agreement.

         SECTION 13.    AGREEMENT OF WARRANT HOLDERS.  Every holder of a
Warrant, by his acceptance thereof, consents and agrees with the Company, the
Warrant Agent and every other holder of a Warrant that:

         (a)  The Warrants are transferable only on the registry books of the
Warrant Agent by the Registered Holder thereof in person or by his attorney duly
authorized in writing and only if the Warrant Certificates representing such
Warrants are surrendered at the office of the Warrant Agent, duly endorsed or
accompanied by a proper instrument of transfer satisfactory to the Warrant Agent
and the Company in their sole discretion, together with payment of any
applicable transfer taxes; and

         (b)  The Company and the Warrant Agent may deem and treat the person
in whose name the Warrant Certificate is registered as the holder and as the
absolute, true and lawful owner of the Warrants represented thereby for all
purposes, and neither the Company nor the Warrant Agent shall be affected by any
notice or knowledge to the contrary, except as otherwise expressly provided in
Section 7 hereof.

<PAGE>

         SECTION 14.    CANCELLATION OF WARRANT CERTIFICATES.  If the Company
shall purchase or acquire any Warrant or Warrants, the Warrant Certificate or
Warrant Certificates evidencing the same shall thereupon be delivered to the
Warrant Agent and cancelled by it and retired.  The Warrant Agent shall also
cancel the Warrant Certificate or Warrant Certificates following exercise of any
or all of the Warrants represented thereby or delivered to it for transfer or
exchange.

         SECTION 15.    CONCERNING THE WARRANT AGENT.  The Warrant Agent acts
hereunder as agent and in a ministerial capacity for the Company, and its duties
shall be determined solely by the provisions hereof.  The Warrant Agent shall
not, by issuing and delivering Warrant Certificates or by any other act
hereunder be deemed to make any representations as to the validity, value or
authorization of the Warrant Certificates or the Warrants represented thereby or
of any securities or other property delivered upon exercise of any Warrant or
whether any stock issued upon exercise of any Warrant is fully paid and
nonassessable.

              The Warrant Agent shall not at any time be under any duty or
responsibility to any holder of Warrant Certificates to make or cause to be made
any adjustment of the Purchase Price or the Redemption Price provided in this
Agreement, or to determine whether any fact exists which may require any such
adjustments, or with respect to the nature or extent of any such adjustment,
when made, or with respect to the method employed in making the same.  It shall
not (i) be liable for any recital or statement of facts contained herein or for
any action taken, suffered or omitted by it in reliance on any Warrant
Certificate or other document or instrument believed by it in good faith to be
genuine and to have been signed or presented by the proper party or parties,
(ii) be responsible for any failure on the part of the Company to comply with
any of its covenants and obligations contained in this Agreement or in any
Warrant Certificate, or (iii) be liable for any act or omission in connection
with this Agreement except for its own negligence or wilful misconduct.

              The Warrant Agent may at any time consult with counsel
satisfactory to it (who may be counsel for the Company) and shall incur no
liability or responsibility for any action taken, suffered or omitted by it in
good faith in accordance with the opinion or advice of such counsel.

              Any notice, statement, instruction, request, direction, order or
demand of the Company shall be sufficiently evidenced by an instrument signed by
the Chairman of the Board, President, any Vice President, its Secretary, or
Assistant Secretary, (unless other evidence in respect thereof is herein
specifically prescribed).  The Warrant Agent shall not be liable for any action
taken, suffered or omitted by it in accordance with such notice, statement,
instruction, request, direction, order or demand believed by it to be genuine.

              The Company agrees to pay the Warrant Agent reasonable
compensation for its services hereunder and to reimburse it for its reasonable
expenses hereunder; it further agrees to indemnify the Warrant Agent and save it
harmless against any and all losses, expenses and liabilities, including
judgments, costs and counsel fees, for anything done or omitted by the


                                         -18-

<PAGE>

Warrant Agent in the execution of its duties and powers hereunder except losses,
expenses and liabilities arising as a result of the Warrant Agent's negligence
or wilful misconduct.

              The Warrant Agent may resign its duties and be discharged from
all further duties and liabilities hereunder (except liabilities arising as a
result of the Warrant Agent's own negligence or wilful misconduct), after giving
30 days' prior written notice to the Company.  At least 15 days prior to the
date such resignation is to become effective, the Warrant Agent shall cause a
copy of such notice of resignation to be mailed to the Registered Holder of each
Warrant Certificate at the Company's expense.  Upon such resignation, or any
inability of the Warrant Agent to act as such hereunder, the Company shall
appoint a new warrant agent in writing.  If the Company shall fail to make such
appointment within a period of 15 days after it has been notified in writing of
such resignation by the resigning Warrant Agent, then the Registered Holder of
any Warrant Certificate may apply to any court of competent jurisdiction for the
appointment of a new warrant agent.  Any new warrant agent, whether appointed by
the Company or by such a court, shall be a bank or trust company having a
capital and surplus, as shown by its last published report to its stockholders,
of not less than $10,000,000 or a stock transfer company that is a registered
transfer agent under the Securities Exchange Act of 1934.  After acceptance in
writing of such appointment by the new warrant agent is received by the Company,
such new warrant agent shall be vested with the same powers, rights, duties and
responsibilities as if it had been originally named herein as the Warrant Agent,
without any further assurance, conveyance, act or deed; but if for any reason it
shall be necessary or expedient to execute and deliver any further assurance,
conveyance, act or deed, the same shall be done at the expense of the Company
and shall be legally and validly executed and delivered by the resigning Warrant
Agent.  Not later than the effective date of any such appointment the Company
shall file notice thereof with the resigning Warrant Agent and shall forthwith
cause a copy of such notice to be mailed to the Registered Holder of each
Warrant Certificate.

              Any corporation into which the Warrant Agent or any new warrant
agent may be converted or merged or any corporation resulting from any
consolidation to which the Warrant Agent or any new warrant agent shall be a
party or any corporation succeeding to the trust business of the Warrant Agent
shall be a successor warrant agent under this Agreement without any further act,
provided that such corporation is eligible for appointment as successor to the
Warrant Agent under the provisions of the preceding paragraph.  Any such
successor warrant agent shall promptly cause notice of its succession as warrant
agent to be mailed to the Company and to the Registered Holder of each Warrant
Certificate.

              The Warrant Agent, its subsidiaries and affiliates, and any of
its or their officers or directors, may buy and hold or sell Warrants or other
securities of the Company and otherwise deal with the Company in the same manner
and to the same extent and with like effects as though it were not Warrant
Agent.  Nothing herein shall preclude the Warrant Agent from acting in any other
capacity for the Company or for any other legal entity.

         SECTION 16.    MODIFICATION OF AGREEMENT.  Subject to the provisions
of Section 4(b), the parties hereto and the Company may by supplemental
agreement make any

cure any ambiguity or to correct any defective or inconsistent provision or

resulting from a subsequent public offering of Company securities which includes
Class A or Class B Warrants having the same terms and conditions as the Class A
or Class B Warrants, respectively, originally covered by or subsequently added
to this Agreement under this Section 16; or (iii) that they may deem necessary
or desirable and which shall not adversely affect the interests of the holders
of Warrant Certificates; PROVIDED, HOWEVER, that this Agreement shall not
otherwise be modified, supplemented or altered in any respect except with the
consent in writing of the Registered Holders of Warrant Certificates
representing not less than 50% of the Warrants then outstanding; and PROVIDED,
FURTHER, that no change in the number or nature of the securities purchasable
upon the exercise of any Warrant, or the Purchase Price therefor, or the
acceleration of the Warrant Expiration Date, shall be made without the consent
in writing of the Registered Holder of the Warrant Certificate representing such
Warrant, other than such changes as are specifically prescribed by this
Agreement as originally executed or are made in compliance with applicable law.

         SECTION 17.    NOTICES.  All notices, requests, consents and other
communications hereunder shall be in writing and shall be deemed to have been

construed in accordance with the laws of the State of New York, without
reference to principles of conflict of laws.

         SECTION 19.    BINDING EFFECT.  This Agreement shall be binding upon
and inure to the benefit of the Company and, the Warrant Agent and their
respective successors and assigns, and the holders from time to time of Warrant
Certificates .  Nothing in this Agreement is intended or shall be construed to
confer upon any other person any right, remedy or claim, in equity or at law, or
to impose upon any other person any duty, liability or obligation.

         SECTION 20.    TERMINATION.  This Agreement shall terminate at the
close of business on the earlier of the Warrant Expiration Date or the date upon
which all Warrants (including the warrants issuable upon exercise of the Unit
Purchase Options) have been exercised, except that the Warrant Agent shall
account to the Company for cash held by it and the provisions of Section 15
hereof shall survive such termination.

               OF CLASS A COMMON STOCK AND REDEEMABLE CLASS B WARRANTS

                       Advanced Aerodynamics & Structures, Inc.


         This certifies that FOR VALUE RECEIVED __________________ or
registered assigns (the "Registered Holder") is the owner of the number of Class
A Warrants ("Class A Warrants") specified above.  Each Class A Warrant
represented hereby initially entitles the Registered Holder to purchase, subject
to the terms and conditions set forth in this Warrant Certificate and the
Warrant Agreement (as hereinafter defined), one fully paid and nonassessable
share of Class A Common Stock, $.0001 value ("Class A Common Stock"), of
Advanced Aerodynamics & Structures, Inc., a Delaware corporation (the
"Company"), and one Class B Warrant of the Company at any time between _______,
1996, and the Expiration Date (as hereinafter defined), upon the presentation
and surrender of this Warrant Certificate with the Subscription Form on the
reverse hereof duly executed, at the corporate office of American Stock Transfer
& Trust Company as Warrant Agent, or its successor (the "Warrant Agent"),
accompanied by payment of $6.50 (the "Purchase Price") in lawful money of the
United States of America in cash or by official bank or certified check made
payable to the Company.

         This Warrant Certificate and each Class A Warrant represented hereby
are issued pursuant to and are subject in all respects to the terms and
conditions set forth in the Warrant Agreement (the "Warrant Agreement"), dated
_________ __, 1996, by and among the Company, the Warrant Agent and D.H.  Blair

         In the event of certain contingencies provided for in the Warrant

and Class B Warrants subject to purchase upon the exercise of each Class A
Warrant represented hereby are subject to modification or adjustment.

         Each Class A Warrant represented hereby is exercisable at the option

cancel this Warrant Certificate upon the surrender hereof and shall execute and
deliver a new Warrant Certificate or Warrant Certificates of like tenor, which
the Warrant Agent shall countersign, for the balance of such Class A Warrants.

         The term "Expiration Date" shall mean 5:00 P.M.  (New York time) on
____________ ___, 2001, or such earlier date as the Class A Warrants shall be
redeemed.  If such date shall in the State of New York be a holiday or a day on

not a holiday or a day on which banks are authorized to close.

         The Company shall not be obligated to deliver any securities pursuant
to the exercise of the Class A Warrants represented hereby unless a registration
statement under the Securities Act of 1933, as amended, with respect to such
securities is effective.  The Company has covenanted and agreed that it will
file a registration statement and will use its best efforts to cause the same to
become effective and to keep such registration statement current while any of
the Class A Warrants are outstanding.  The Class A Warrants represented hereby
shall not be exercisable by a Registered Holder in any state where such exercise
would be unlawful.

         This Warrant Certificate is exchangeable, upon the surrender hereof by
the Registered Holder at the corporate office of the Warrant Agent, for a new
Warrant Certificate or Warrant Certificates of like tenor representing an equal
aggregate number of Class A Warrants, each of such new Warrant Certificates to
represent such number of Class A Warrants as shall be designated by such
Registered Holder at the time of such surrender.  Upon due presentment with any
applicable transfer fee per certificate in addition to any tax or other
governmental charge imposed in connection therewith, for registration of
transfer of this Class A Warrant Certificate at such office, a new Warrant
Certificate or Warrant Certificates representing an equal aggregate number of
Class A Warrants will be issued to the transferee in exchange therefor, subject
to the limitations provided in the Warrant Agreement.

         Prior to the exercise of any Class A Warrant represented hereby, the
Registered Holder shall not be entitled to any rights of a stockholder of the
Company, including, without limitation, the right to vote or to receive
dividends or other distributions, and shall not be entitled to receive any
notice of any proceedings of the Company, except as provided in the Warrant
Agreement.

         The Class A Warrants represented hereby may be redeemed at the option
of the Company, at a redemption price of $.05 per Class A Warrant at any time
after ___________ __, 1997, provided the Market Price (as defined in the Warrant
Agreement) for the  Class A Common Stock shall exceed $12.00 per share.  Notice
of redemption shall be given not later than the thirtieth day before the date
fixed for redemption, all as provided in the Warrant Agreement.  On and after
the date fixed for redemption, the Registered Holder shall have no rights with
respect to the Class A Warrants represented hereby except to receive the $.05
per Class A Warrant upon surrender of this Warrant Certificate.

         Prior to due presentment for registration of transfer hereof, the
Company and the Warrant Agent may deem and treat the Registered Holder as the
absolute owner hereof and of each Class A Warrant represented hereby
(notwithstanding any notations of ownership or writing hereon made by anyone
other than a duly authorized officer of the Company or the Warrant Agent) for
all purposes and shall not be affected by any notice to the contrary.

         The Company has agreed to pay a fee of 5% of the Purchase Price upon
certain conditions as specified in the Warrant Agreement upon the exercise of
the Class A Warrants represented hereby.

         This Warrant Certificate shall be governed by and construed in
accordance with the laws of the State of New York.

                                 UNIT PURCHASE OPTION
                                Dated:  _______, 1996.


         THIS CERTIFIES THAT______________ (herein sometimes called the
"Holder") is entitled to purchase from Advanced Aerodynamics & Structures, Inc.,
a Delaware corporation (hereinafter called the "Company"), at the prices and
during the periods as hereinafter specified, up to _______ (_______) Units
("Units"), each Unit consisting of one share of the Company's Class A Common
Stock, $.0001 par value, as now constituted ("Class A Common Stock"), one
Class A warrant ("Class A Warrants") and one Class B warrant ("Class B
Warrants").  Each Class A Warrant is exercisable to purchase one share of Class
A Common Stock and one Class B Warrant at an exercise price of $6.50 from
_______, 1996 to _______ , 2001, and each Class B Warrant is exercisable to
purchase one share of Class A Common Stock at an exercise price of $8.75 until
_______, 2001.  The Class A Warrants and Class B Warrants are herein
collectively referred to as the "Warrants."

         The Units have been registered under a Registration Statement on
Form SB-2, (File No. 33-_______ ) declared effective by the Securities and
Exchange Commission on _______ (the "Registration Statement").  This Option,
together with options of like tenor, constituting in the aggregate options (the
"Options") to purchase 500,000 Units, subject to adjustment in accordance with
Section 8 of this Option (the "Option Units"), was originally issued pursuant to
an underwriting agreement between the Company and D.H. Blair Investment Banking
Corp., as underwriter (the "Underwriter") in connection with a public offering
(the "Offering") of 5,000,000 Units (the "Public Units") through the
Underwriter, in consideration of $_______ received for the Options.

         Except as specifically otherwise provided herein, the Class A Common
Stock and the Warrants issued pursuant to the option herein granted (the
"Option") shall bear the same terms and conditions as described under the
caption "Description of Securities" in the Registration Statement, and the
Warrants shall be governed by the terms of the Warrant Agreement dated as of
_______, 1996 executed in connection with such public offering (the "Warrant
Agreement"), and except that (i) the holder shall have registration rights under
the Securities Act of 1933, as amended (the "Act"), for the Option, the Class A
Common Stock and the Warrants included in the Option Units, and the shares of
Class A Common Stock underlying the Warrants, as more fully described in
Section 6 of this Option and (ii) the Warrants issuable upon exercise of the
Option will be subject to redemption by the Company pursuant to the Warrant
Agreement at any time after the Option has been exercised and the Warrants
underlying the Option Units are outstanding.  Any such redemption shall be on
the same terms and


<PAGE>

conditions as the Warrants included in the Public Units (the "Public Warrants").
The Company will list the Class A Common Stock underlying this Option and, at
the Holder's request the Warrants, on the Nasdaq National Market, the Nasdaq
SmallCap Market or such other exchange or market as the Class A Common Stock or
Public Warrants may then be listed or quoted.  In the event of any extension of
the expiration date or reduction of the exercise price of the Public Warrants,
the same changes to the Warrants included in the Option Units shall be
simultaneously effected.

         1.   The rights represented by this Option shall be exercised at the
prices, subject to adjustment in accordance with Section 8 of this Option ("the
"Exercise Price"), and during the periods as follows:

                   (a)  During the period from _______, 1996 to _______, 1998
              inclusive, the Holder shall have no right to purchase any Option
              Units hereunder, except that in the event of any merger,
              consolidation or sale of all or substantially all the capital
              stock or assets of the Company or in the case of any statutory
              exchange of securities with another corporation (including any
              exchange effected in connection with a merger of another
              corporation into the Company) subsequent to _______, the Holder
              shall have the right to exercise this Option and the Warrants
              included herein at such time and receive the kind and amount of
              shares of stock and other securities and property (including
              cash) which a holder of the number of shares of Class A Common
              Stock underlying this Option and the Warrants included in this
              Option would have owned or been entitled to receive had this
              Option been exercised immediately prior thereto.

                   (b)  Between _______, 1998 and _______,2001 inclusive, the
              Holder shall have the option to purchase Option Units hereunder
              at a price of $_______ per Unit.  For purposes of the adjustments
              under Section 8 hereof, the Per Share Exercise Price shall be
              deemed to be $_______, subject to further adjustment as provided
              in such Section 8.

                   (c)  After _________, 2001 the Holder shall have no right to
              purchase any Units hereunder.

         2.   (a)  The rights represented by this Option may be exercised at
any time within the period above specified, in whole or in part, by (i) the
surrender of this Option (with the purchase form at the end hereof properly
executed) at the principal executive office of the Company (or such other office
or agency of the Company as it may designate by notice in writing to the Holder
at the address of the Holder appearing on the books of the Company); and
(ii) payment to the Company of the exercise price then in effect for the number
of Option Units specified in the above-mentioned purchase form together with
applicable stock transfer taxes, if any.  This Option shall be deemed to have
been exercised, in whole or in part to the extent specified, immediately prior
to the close of business on the date this Option is surrendered and


                                         -2-

<PAGE>

payment is made in accordance with the foregoing provisions of this Section 2,
and the person or persons in whose name or names the certificates for shares of
Class A Common Stock and Warrants shall be issuable upon such exercise shall
become the holder or holders of record of such Class A Common Stock and Warrants
at that time and date.  The certificates for the Class A Common Stock and
Warrants so purchased shall be delivered to the Holder as soon as practicable
but not later than ten (10) days after the rights represented by this Option
shall have been so exercised.

              (b)  At any time during the period above specified, during which
this Option may be exercised, the Holder may, at its option, exchange this
Option, in whole or in part (an "Option Exchange"), into the number of Option
Units determined in accordance with this Section (b), by surrendering this
Option at the principal office of the Company or at the office of its stock
transfer agent, accompanied by a notice stating such Holder's intent to effect
such exchange, the number of Option Units into which this Option is to be
exchanged and the date on which the Holder requests that such Option Exchange
occur (the "Notice of Exchange").  The Option Exchange shall take place on the
date specified in the Notice of Exchange or, if later, the date the Notice of
Exchange is received by the Company (the "Exchange Date").  Certificates for the
shares of Class A Common Stock and Warrants issuable upon such Option Exchange
and, if applicable, a new Option of like tenor evidencing the balance of the
Option Units remaining subject to this Option, shall be issued as of the
Exchange Date and delivered to the Holder within seven (7) days following the
Exchange Date.  In connection with any Option Exchange, this Option shall
represent the right to subscribe for and acquire the number of Option Units
(rounded to the next highest integer) equal to (x) the number of Option Units
specified by the Holder in its Notice of Exchange up to the maximum number of
Option Units subject to this option (the "Total Number") less (y) the number of
Option Units equal to the quotient obtained by dividing (A) the product of the
Total Number and the existing Exercise Price by (B) the Fair Market Value.
"Fair Market Value" shall mean first, if there is a trading market as indicated
in Subsection (i) below for the Units, such Fair Market Value of the Units and
if there is no such trading market in the Units, then Fair Market Value shall
have the meaning indicated in Subsections (ii) through (v) below for the
aggregate value of all shares of Class A Common Stock and Warrants which
comprise a Unit:

              (i)    If the Units are listed on a national securities exchange
         or listed or admitted to unlisted trading privileges on such exchange
         or listed for trading on the Nasdaq National Market or the Nasdaq
         SmallCap Market, the Fair Market Value shall be the average of the
         last reported sale prices or the average of the means of the last
         reported bid and asked prices, respectively, of the Units on such
         exchange or market for the twenty (20) business days ending on the
         last business day prior to the Exchange Date; or

              (ii)   If the Class A Common Stock or Warrants are listed on a
         national securities exchange or admitted to unlisted trading
         privileges on such exchange or listed for trading on the Nasdaq
         National Market or the Nasdaq SmallCap Market, the Fair Market Value
         shall be the average of the last reported sale prices or the


                                         -3-

<PAGE>

         average of the means of the last reported bid and asked prices,
         respectively, of Class A Common Stock or Warrants, respectively, on
         such exchange or market for the twenty (20) business days ending on
         the last business day prior to the Exchange Date; or

              (iii)  If the Class A Common Stock or Warrants are not so listed
         or admitted to unlisted trading privileges, the Fair Market Value
         shall be the average of the means of the last reported bid and asked
         prices of the Class A Common Stock or Warrants, respectively, for the
         twenty (20) business days ending on the last business day prior to the
         Exchange Date; or

              (iv)   If the Class A Common Stock is not so listed or admitted
         to unlisted trading privileges and bid and asked prices are not so
         reported, the Fair Market Value shall be an amount, not less than book
         value thereof as at the end of the most recent fiscal year of the
         Company ending prior to the Exchange Date, determined in such
         reasonable manner as may be prescribed by the Board of Directors of
         the Company; or

              (v)    If the Warrants are not so listed or admitted to unlisted
         trading privileges, and bid and asked prices are not so reported for
         Warrants, then Fair Market Value for the Warrants shall be an amount
         equal to the difference between (i) the Fair Market Value of the
         shares of Class A Common Stock and Warrants which may be received upon
         the exercise of the Warrants, as determined herein, and (ii) the
         Warrant Exercise Price.

         3.   Neither this Option nor the underlying securities shall be
transferred, sold, assigned, or hypothecated for a period of two years
commencing on the effective date of the Registraton Statement except that they
may be transferred to successors of the Holder, and may be assigned in whole or
in part to any person who is an officer of the Holder, any member participating
in the selling group relating to the Offering or any officer of such selling
group member.  Any such assignment shall be effected by the Holder (i) executing
the form of assignment at the end hereof and (ii) surrendering this Option for
cancellation at the office or agency of the Company referred to in Section 2
hereof, accompanied by a certificate (signed by an officer of the Holder if the
Holder is a corporation), stating that each transferee is a permitted transferee
under this Section 3 hereof; whereupon the Company shall issue, in the name or
names specified by the Holder (including the Holder) a new Option or Options of
like tenor and representing in the aggregate rights to purchase the same number
of Option Units as are purchasable hereunder.

         4.   The Company covenants and agrees that all shares of Class A
Common Stock which may be issued as part of the Option Units purchased hereunder
and the Class A Common Stock which may be issued upon exercise of the Warrants
will, upon issuance, be duly and validly issued, fully paid and nonassessable
and no personal liability will attach to the holder thereof.  The Company
further covenants and agrees that during the periods within which this


                                         -4-

<PAGE>

Option may be exercised, the Company will at all times have authorized and
reserved a sufficient number of shares of its Class A Common Stock to provide
for the exercise of this Option and that it will have authorized and reserved a
sufficient number of shares of Class A Common Stock for issuance upon exercise
of the Warrants included in the Option Units.

         5.   This Option shall not entitle the Holder to any voting rights or
any other rights, or subject to the Holder to any liabilities, as a stockholder
of the Company.

         6.   (a)  The Company shall advise the Holder or its transferee,
whether the Holder holds the Option or has exercised the Option and holds Option
Units or any of the securities underlying the Option Units, by written notice at
least four weeks prior to the filing of any post-effective amendment to the
Registration Statement or of any new registration statement or post-effective
amendment thereto under the Act covering any securities of the Company, for its
own account or for the account of others, and will for a period of seven years
from the effective date of the Registration Statement, upon the request of the
Holder, include in any such post-effective amendment or registration statement,
such information as may be required to permit a public offering of the Option,
all or any of the Option Units, the Class A Common Stock or Warrants included in
the Option Units or the Class A Common Stock issuable upon the exercise of the
Warrants (the "Registrable Securities").

              (b)  If D.H. Blair Investment Banking Corp., D.H. Blair & Co.,
Inc. or J. Morton Davis (each, a "Majority Holder") shall give notice to the
Company at any time to the effect that such holder desires to register under the
Act this Option, the Option Units or any of the underlying securities contained
in the Option Units under such circumstances that a public distribution (within
the meaning of the Act) of any such securities will be involved then the Company
will promptly, but no later than two weeks after receipt of such notice, file a
post-effective amendment to the current Registration Statement or a new
registration statement on Form S-1 or such other form as the holder requests
pursuant to the Act, to the end that the Option, the Option Units and/or any of
the securities underlying the Option Units may be publicly sold under the Act as
promptly as practicable thereafter and the Company will use its best efforts to
cause such registration to become and remain effective (including the taking of
such steps as are necessary to obtain the removal of any stop order); provided,
that such holder shall furnish the Company with appropriate information in
connection therewith as the Company may reasonably request in writing.  A
Majority Holder may, at its option, request the filing of a post-effective
amendment to the current Registration Statement or a new registration statement
under the Act on one occasion during the four year period beginning one year
from the effective date of the Registration Statement.  The Holder may, at its
option request the registration of the Option and/or any of the securities
underlying the Option in a registration statement made by the Company as
contemplated by Section 6(a) or in connection with a request made pursuant to
this Section 6(b) prior to acquisition of the Option Units issuable upon
exercise of the Option and even though the Holder has not given notice of
exercise of the Option.  A Majority Holder may, at its option, request such
post-effective amendment or new registration statement during the described
period with respect to the Option, the Option Units as a unit, or separately as
to the Class A Common Stock and/or Warrants included in the Option Units and/or
the Class A


                                         -5-

<PAGE>

Common Stock issuable upon the exercise of the Warrants, and such registration
rights may be exercised by a Majority Holder prior to or subsequent to the
exercise of the Option.

         Within ten days after receiving any such notice pursuant to this
Section 6(b), the Company shall give notice to the other holders of the Options,
advising that the Company is proceeding with such post-effective amendment or
registration statement and offering to include therein the securities underlying
the Options of the other holders, provided that they shall furnish the Company
with such appropriate information (relating to the intentions of such holders)
in connection therewith as the Company shall reasonably request in writing.  In
the event the registration statement is not filed within the period specified
herein and in the event the registration statement is not declared effective
under the Act prior to ________, 2001, then, at the holders' request, the
Company shall purchase the Options from the holder for a per option price equal
to the difference between (i) the Fair Market Value of the Class A Common Stock
on the date of notice multiplied by the number of shares of Class A Common Stock
issuable upon exercise of the Option and the underlying Warrants and (ii) the
average per share purchase price of the Option and each share of Class A Common
Stock underlying the Option.  All costs and expenses of the first such
post-effective amendment or new registration statement under this paragraph 6(b)
shall be borne by the Company, except that the holders shall bear the fees of
their own counsel and any underwriting discounts or commissions applicable to
any of the securities sold by them.  If the Company determines to include
securities to be sold by it in any registration statement originally requested
pursuant to this Section 6(b), such registration shall instead be deemed to have
been a registration under Section 6(a) and not under this Section 6(b).

         The Company will maintain such registration statement or
post-effective amendment current under the Act for a period of at least six
months (and for up to an additional three months if requested by the Holder)
from the effective date thereof.

              (c)  Whenever pursuant to Section 6 a registration statement
relating to any Registrable Securities is filed under the Act, amended or
supplemented, the Company shall (i) supply prospectuses and such other documents
as the Holder may request in order to facilitate the public sale or other
disposition of the Registrable Securities, (ii) use its best efforts to register
and qualify any of the Registrable Securities for sale in such states as such
Holder designates, (iii) furnish indemnification in the manner provided in
Section 7 hereof, (iv) notify each Holder of Registrable Securities at any time
when a prospectus relating thereto is required to be delivered under the
Securities Act, of the happening of any event as a result of which the
prospectus included in such registration statement, as then in effect, contains
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 and, at the request of any such Holder, prepare and furnish to such
Holder a reasonable number of copies of a supplement to or an amendment of such
prospectus as may be necessary so that, as thereafter delivered to the
purchasers of such Registrable Securities, such prospectus shall not included an
untrue statement of a material fact or omit to state material fact required to
be stated therein or necessary to make the statements therein not misleading and
(v) do any and all other acts and things which may be necessary or desirable to
enable such Holders to consummate the public sale or other disposition of the


                                         -6-

<PAGE>

Registrable Securities, The Holder shall furnish appropriate information in
connection therewith and indemnification as set forth in Section 7.

              (d)  The Company shall not permit the inclusion of any securities
other than the Registrable Securities to be included in any registration
statement filed pursuant to Section 6(b) hereof without the prior written
consent of a Majority Holder.

              (e)  The Company shall furnish to each Holder participating in
the offering and to each underwriter, if any, a signed counterpart, addressed to
such Holder or underwriter, of (i) an opinion of counsel to the Company, dated
the effective date of such registration statement (or, if such registration
includes an underwritten public offering, an opinion dated the date of the
closing under the underwriting agreement), and (ii) if such registration
includes an underwritten public offering, a "cold comfort" letter dated the
effective date of such registration statement and dated the date of the closing
under the underwriting agreement signed by the independent public accountants
who have issued a report on the Company's financial statements included in such
registration statement, in each case covering substantially the same matters
with respect to such registration statement (and the prospectus included
therein) and, in the case of such accountants' letter, with respect to events
subsequent to the date of such financial statements, as are customarily covered
in opinions of issuer's counsel and in accountants' letters delivered to
underwriters in underwritten public offerings of securities.

              (f)  The Company shall deliver promptly to each Holder
participating in the offering requesting the correspondence and memoranda
described below and to the managing underwriter copies of all correspondence
between the Commission and the Company, its counsel or auditors and all
memoranda relating to discussions with the Commission or its staff with respect
to the registration statement and permit each Holder and underwriter to do such
investigation, upon reasonable advance notice, with respect to information
contained in or omitted from the registration statement as it deems reasonable
necessary to comply with applicable securities laws or rules of the National
Association of Securities Dealers, Inc.  ("NASD").  Such investigation shall
include access to non-confidential books, records and properties and
opportunities to discuss the business of the Company with its officers and
independent auditors, all to such reasonable extent and at such reasonable times
as any such Holder shall reasonably request.

         7.   (a)  Whenever pursuant to Section 6 a registration statement
relating to the Registrable Securities is filed under the Act, amended or
supplemented, the Company will indemnify and hold harmless each holder of the
Registrable Securities covered by such registration statement, amendment or
supplement (such holder being hereinafter called the "Distributing Holder"), and
each person, if any, who controls (within the meaning of the Act) the
Distributing Holder, and each underwriter (within the meaning of the Act) of
such securities and each person, if any, who controls (within the meaning of the
Act) any such underwriter, against any losses, claims, damages or liabilities,
joint or several, to which the Distributing Holder, any such controlling person
or any such underwriter may become subject, under the Act or


                                         -7-

<PAGE>

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 such registration
statement or any preliminary prospectus or final prospectus constituting a part
thereof or any amendment or supplement thereto, or arise out of or are based
upon the 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 Distributing Holder and each such controlling person and underwriter for any
legal or other expenses reasonably incurred by the Distributing Holder or such
controlling person or underwriter 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 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 said
registration statement, said preliminary prospectus, said final prospectus or
said amendment or supplement in reliance upon and in conformity with written
information furnished by such Distributing Holder specifically for use in the
preparation thereof.

              (b)  If requested by the Company prior to the filing of any
registration statement covering the Registrable Securities, each Distributing
Holder will agree, severally but not jointly, to indemnify and hold harmless the
Company against any losses, claims, damages or liabilities to which the Company
may become subject, under the Act or otherwise, insofar as such losses, claims,
damages or liabilities arise out of or are based upon any untrue or alleged
untrue statement of any material fact contained in said registration statement,
said preliminary prospectus, said final prospectus, or said amendment or
supplement, or arise out of or are based upon the omission or the alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, in each case to the
extent, but only to the extent that such untrue statement or alleged untrue
statement or omission or alleged omission was made in said registration
statement, said preliminary prospectus, said final prospectus or said amendment
or supplement in reliance upon and in conformity with written information
furnished by such Distributing Holder specifically for use in the preparation
thereof; except that the maximum amount which may be recovered from the
Distributing Holder pursuant to this Section 7 or otherwise shall be limited to
the amount of net proceeds received by the Distributing Holder from the sale of
the Registrable Securities.

              (c)  Promptly after receipt by an indemnified party under this
Section 7 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against any indemnifying
party, give the indemnifying party notice of the commencement thereof; but the
omission so to notify the indemnifying party will not relieve it from any
liability which it may have to any indemnified party otherwise than under this
Section 7.

              (d)  In case any such action is brought against any indemnified
party, and it notifies an indemnifying party of the commencement thereof, the
indemnifying party will be entitled to participate in, and, to the extent that
it may wish, jointly with any other indemnifying party similarly notified to
assume the defense thereof, with counsel reasonably


                                         -8-

<PAGE>

satisfactory to such indemnified party, and after notice from the indemnifying
party to such indemnified party of its election so to assume the defense
thereof, the indemnifying party will not be liable to such indemnified party
under this Section 7 for any legal or other expenses subsequently incurred by
such indemnified party in connection with the defense thereof other than
reasonable costs of investigation.

         (8)  In addition to the provisions of Section 1(a) of this Option, the
Exercise Price in effect at any time and the number and kind of securities
purchasable upon the exercise of the Options shall be subject to adjustment from
time to time upon the happening of certain events as follows:

              (a)  In case the Company shall (i) declare a dividend or make a
         distribution on its outstanding shares of Common Stock in shares of
         Common Stock, (ii) subdivide or reclassify its outstanding shares of
         Common Stock into a greater number of shares, or (iii) combine or
         reclassify its outstanding shares of Common Stock into a smaller
         number of shares, the Exercise Price in effect at the time of the
         record date for such dividend or distribution or of the effective date
         of such subdivision, combination or reclassification shall be adjusted
         so that it shall equal the price determined by multiplying the
         Exercise Price by a fraction, the denominator of which shall be the
         number of shares of Common Stock outstanding after giving effect to
         such action, and the numerator of which shall be the number of shares
         of Common Stock outstanding immediately prior to such action.  Such
         adjustment shall be made successively whenever any event listed above
         shall occur.

              (b)  Whenever the Exercise Price payable upon exercise of each
         Option is adjusted pursuant to Subsection (a) above, (i) the number of
         shares of Class A Common Stock included in an Option Unit shall
         simultaneously be adjusted by multiplying the number of shares of
         Class A Common Stock included in Option Unit immediately prior to such
         adjustment by the Exercise Price in effect immediately prior to such
         adjustment and dividing the product so obtained by the Exercise Price,
         as adjusted and (ii) the number of shares of Class A Common Stock or
         other securities issuable upon exercise of the Warrants included in
         the Option Units and the exercise price of such Warrants shall be
         adjusted in accordance with the applicable terms of the Warrant
         Agreement.

              (c)  Whenever the Exercise Price is adjusted, as herein provided,
         the Company shall promptly but no later than 10 days after any request
         for such an adjustment by the Holder, cause a notice setting forth the
         adjusted Exercise Price and adjusted number of Option Units issuable
         upon exercise of each Option and, if requested, information describing
         the transactions giving rise to such adjustments, to be mailed to the
         Holders, at the address set forth herein, and shall cause a certified
         copy thereof to be mailed to its transfer agent, if any.  The Company
         may retain a firm of independent certified public accountants selected


                                         -9-

<PAGE>

         by the Board of Directors (who may be the regular accountants employed
         by the Company) to make any computation required by this Section 8,
         and a certificate signed by such firm shall be conclusive evidence of
         the correctness of such adjustment.

              (d)  In the event that at any time, as a result of an adjustment
         made pursuant to Subsection (a) above, the Holder of this Option
         thereafter shall become entitled to receive any shares of the Company,
         other than Class A Common Stock, thereafter the number of such other
         shares so receivable upon exercise of this Option shall be subject to
         adjustment from time to time in a manner and on terms as nearly
         equivalent as practicable to the provisions with respect to the Class
         A Common Stock contained in Subsections (a) to (c), inclusive above.

              (e)  In case any event shall occur as to which the other
         provisions of this Section 8 or Section 1(a) hereof are not strictly
         applicable but as to which the failure to make any adjustment would
         not fairly protect the purchase rights represented by this Option in
         accordance with the essential intent and principles hereof then, in
         each such case, the Holders of Options representing the right to
         purchase a majority of the Option Units may appoint a firm of
         independent public accountants reasonably acceptable to the Company,
         which shall give their opinion as to the adjustment, if any, on a
         basis consistent with the essential intent and principles established
         herein, necessary to preserve the purchase rights represented by the
         Options.  Upon receipt of such opinion, the Company will promptly mail
         a copy thereof to the Holder of this Option and shall make the
         adjustments described therein.  The fees and expenses of such
         independent public accountants shall be borne by the Company.

         9.   This Agreement shall be governed by and in accordance with the
laws of the State of New York, without giving effect to the principles of
conflicts of law thereof.

         IN WITNESS WHEREOF, Advanced Aerodynamics & Structures, Inc. has
caused this Option to be signed by its duly authorized officers under its
corporate seal, and this Option to be dated ____________, 1996.

Re:  Registration Statement on Form SB-2
 
Ladies and Gentlemen:
 
    We are counsel for Advanced Aerodynamic & Structures, Inc., a Delaware
corporation ("AASI"), in connection with its proposed public offering under the
Securities Act of 1933, as amended, of 5,000,000 units ("Units") consisting of
5,000,000 shares of Class A Common Stock, 5,000,000 of Class A Warrants and
5,000,000 Class B Warrants (5,750,000 Units if the overallotment option is
exercised in full), through a Registration Statement on Form SB-2 as to which
this opinion is a part, to be filed with the Securities and Exchange Commission
(the "Commission").
 
    In connection with rendering our opinion as set forth below, we have
reviewed and examined originals or copies of such corporate records and other
documents and have satisfied ourselves as to such other matters as we have
deemed necessary to enable us to express our opinion hereinafter set forth.
 
    Based upon the foregoing, it is our opinion that:
 
    The Shares covered by the Registration Statement, when issued in accordance
with the terms and conditions set forth therein, will be duly authorized,
validly issued, fully paid, and non-assessable Shares of Common Stock.
 
    The shares of Common Stock being registered for the account of the Selling
Stockholders are duly authorized, validly issued, fully paid and nonassessable
shares of Common Stock.
 
    The shares of Common Stock underlying the Warrants covered by the
Registration Statement, when issued in accordance with the terms and conditions
set forth therein, will be duly authorized, validly issued, fully paid, and
nonassessable.
 
    We hereby consent to the filing of this opinion as an Exhibit to the
Registration Statement and to the reference to this firm under the caption
"Legal Matters" in the Prospectus included in the Registration Statement.
 
                                        Very truly yours,

                              INDEMNIFICATION AGREEMENT


    THIS INDEMNIFICATION AGREEMENT (the "Agreement") is made and effective as
of this 16th day of July, 1996, between Advanced Aerodynamics & Structures,
Inc., a Delaware corporation (the "Company"), and ________________________
("Indemnitee"), an Agent (as defined below) of the Company.

    A.   The Company and Indemnity are aware of the substantial growth in the 
number of lawsuits filed against corporate Agents in connection with their
activities in such capacities and by reason of their status as such.

    B.   The Company and Indemnitee recognize that the cost of defending
against such lawsuits, whether or not meritorious, is typically beyond the
financial resources of most Agents of the Company and often outweighs the
benefits of serving as an Agent of the Company.

    C.   The Company has investigated the availability of liability insurance
to provide its Agents with adequate protection against the foregoing legal risks
and potential liabilities.  It has concluded that, whether or not it shall at
any time purchase such insurance, it is in the best interests of the Company and
its shareholders to contract with its directors, officers and other Agents (as
determined by the Board of Directors of the Company), including indemnitee, to
indemnify them to the fullest extent permitted by law against personal liability
for actions taken in the performance of their duties to the Company.

    D.   Section 145 of the Delaware General Corporation Law, which sets forth
certain provisions relating to mandatory and permissive indemnification of
officers, directors and other Agents of a Delaware corporation by such
corporation, requires indemnification in certain circumstances, permits it in
other circumstances, and prohibits it in some circumstances.

    E.   The Board of Directors of the Company has determined, after due
consideration and investigation of this Agreement and various other options
available, that the following Agreement is reasonable, prudent and necessary to
promote and ensure the best interests of the Company and its shareholders.  This
Agreement is intended to: (i) induce and encourage highly experienced and
capable persons, such as indemnitee, to serve as Agents of the Company;
(ii) encourage such persons to resist what they consider to be unjustifiable
suits and claims made against them in connection with the performance of their
duties to the Company, secure in knowledge that certain expenses, costs, and
liabilities incurred by them in their defense of such litigation will be borne
by the Company and that they will receive the maximum protection against such
risks and liabilities as legally may be made available to them; and
(iii) encourage directors to exercise their best business judgment regarding
matters which come before the Board of Directors without undue concern for the
risk that claims may be made against them on account thereof.

    F.   The Company desires to have Indemnitee serve as Agent of the Company
free from concern about unpredictable, inappropriate or unreasonable legal risks
and personal liabilities by


<PAGE>

reason of his actions or inactions in the performance of his duties to the
Company and its shareholders.  Indemnitee desires to serve as an officer,
director or other Agent of the Company, provided, and on the express condition,
that he is furnished with the indemnity set forth herein.

    NOW, THEREFORE, the Company and Indemnitee hereby agree as follows:

    1.   DEFINITIONS.  For the purposes of this Agreement, the following
definitions shall apply:

         1.1  For the purposes of this Agreement, Indemnitee shall be deemed to
have been acting as an "AGENT" if he was (i) acting in his capacity as a
director or officer of the Company or a member of a committee of the Board of
Directors of the Company, (ii) serving as a director or officer of any other
enterprise at the request of Company, whether or not he was serving in such
capacity at the time any liability or expense is incurred for which
Indemnification or reimbursement can be provided under this Agreement, or
(iii) serving the Company in an agency capacity that the Board of Directors
determines is sufficient to warrant the provision of indemnity pursuant to this
Agreement.

         1.2  "APPLICABLE STANDARD" means that Indemnitee acted in good faith
and in a manner he reasonable believed to be in or not opposed to the best
interests of both the Company and its shareholders; except that in a criminal
proceeding Indemnitee must also have had no reasonable cause to believe that his
conduct was unlawful.  The termination of any Proceeding by judgment, order,
settlement, conviction or upon a plea of nolo contendere or its equivalent shall
not, of itself, create any presumption, or establish, that Indemnitee did not
meet the "Applicable Standard."

         1.3  "EXPENSES" include, without limitation, expenses of Proceedings
(as defined below), including investigations or appeals, court costs, attorneys'
fees and disbursements and any expenses of attempting to establish a right to
Indemnification under law, the Company's Articles of Incorporation, the
Company's Bylaws or this Agreement. Except as is expressly prohibited by
applicable law, "Expenses" shall include the amounts of any judgments, fines or
penalties actually levied against Indemnitee or amounts paid in settlement of a
Proceeding by or on behalf of Indemnitee. With regard to legal fees, the Company
shall have the right to designate, or approve the employment of, counsel for
Indemnitee as a precondition to the requirement to indemnify against Expenses of
such legal counsel.

         1.4  "FINES" shall include any excise tax assessed with respect to any
employee benefit plan.

         1.5  "INDEPENDENT LEGAL COUNSEL" shall include any firm of attorneys
selected by lot from a list consisting of firms which meet minimum size criteria
and other reasonable criteria established by the Board of Directors of the
Company, so long as such firm has not


                                          2

<PAGE>

represented the Company, Indemnitee, any entity controlled by Indemnitee, or any
party adverse to the Company, within the preceding 24 calendar months.

         1.6  "NOT INCONSISTENT WITH THE BEST INTERESTS OF THE COMPANY AND ITS
SHAREHOLDERS" as referred to in this Agreement means that a person has acted in
good faith and in a manner he reasonably believes to be in the interests of the
Company's subsidiaries or affiliates and their respective shareholders, or in
the interests of the participants and beneficiaries of an employee benefit plan.

         1.7  "OTHER ENTERPRISE" shall include employee benefit plans,
committees, subsidiaries and affiliates of the Company.

         1.8  "PROCEEDING" shall include any threatened, pending or completed
action, suit or proceeding (including any appeals therefrom), whether brought in
the name of the Company or otherwise, whether of a civil, criminal,
administrative or investigative nature, and whether in a court or arbitration,
or before or involving a governmental, administrative or private entity
(including, but not limited to, an investigation by the Company or its Board of
Directors), including, but not limited to, actions, suits or proceedings brought
under and/or predicated upon the Securities Act of 1933, as amended, and/or the
Securities Exchange Act of 1934, as amended, and/or their respective state
counterparts, and/or any rule or regulation promulgated thereunder, in which
Indemnitee may be or may have been involved as a party or otherwise (other than
as plaintiff against the Company), by reason of the fact that Indemnitee is or
was an Agent of the Company, by reason of any action taken by him or of any
inaction on his part while acting as such Agent, or by reason of attempting to
establish a right to indemnity under law, the Company's Articles of
Incorporation, the Company's Bylaws or this Agreement.

         1.9  "SERVING AT THE REQUEST OF THE COMPANY" shall include any service
as an Agent of the Company which imposes duties on, or involves services by,
such Agent with respect to any of the Company's subsidiaries, affiliates,
employee benefit plans, such plan's participants or beneficiaries or any other
enterprise.

    2.   AGREEMENT TO SERVE.  Indemnitee agrees to serve or continue to serve
as a director, officer and/or other Agent of the Company at the will of the
Company or under separate contract, as the case may be, for so long as he is
duly elected or appointed, until such time as he tenders his resignation in
writing.

    3.   INDEMNITY.  To the extent permitted by applicable law, as it now
exists or may hereafter be amended, the Company shall indemnify Indemnitee if
Indemnitee is made a party to, or threatened to be made a party to, or otherwise
involved in, any Proceeding by reason of the fact that Indemnitee is or was an
Agent of the Company.  This indemnity shall apply, and be limited, to all
Expenses actually and reasonably incurred by Indemnitee in connection with the
defense or settlement of the Proceeding, unless: (i) it is determined pursuant
to Section 6 of this Agreement or by the court before which such Proceeding was
brought, that Indemnitee did not meet the


                                          3

<PAGE>

Applicable Standard; or (ii) the Proceeding was settled or otherwise disposed of
without court approval.

    4.   EXPENSES OF SUCCESSFUL DEFENSE.  Notwithstanding any other provision
of this Agreement, to the extent that Indemnitee has been successful on the
merits in defense of any Proceeding or in defense of any claim, issue or matter
therein, including the dismissal of an action or portion thereof without
prejudice, Indemnitee shall be indemnified against all Expenses actually and
reasonably incurred in connection therewith.

    5.   ADVANCES OF EXPENSES.  The Expenses incurred by Indemnitee in any
Proceeding shall be advanced by the Company at any time and from time to time
prior to the final disposition of such Proceeding at the written request of
Indemnitee, but only if Indemnitee shall provide the Company with an undertaking
agreement in which Indemnitee agrees to repay such advances. in a manner that is
not inconsistent with this Agreement, if and to the extent that it ultimately
determined that Indemnitee is not entitled to indemnification as provided
herein. Any advance required hereunder shall be deemed to have been approved by
the Board of Directors of the Company to the extent this Agreement was so
approved.  In determining whether or not to make an advance hereunder, the
ability of Indemnitee to repay shall not be a factor.  However, in a Proceeding
brought by the Company directly, in its own right (as distinguished from an
action brought derivatively or by any receiver or trustee), the Company shall
have discretion whether or not to make the advances called for hereby if
Independent Legal Counsel advises in writing that the Company has probable cause
to believe, and the Company does believe, that Indemnitee did not act in good
faith with regard to the subject matter of the Proceeding or a material portion
thereof.

    6.   RIGHT OF INDEMNITEE TO INDEMNIFICATION UPON APPLICATION; PROCEDURE
UPON APPLICATION.  Any indemnification or advance under Sections 4 and/or 5
hereof shall be made no later than 20 days after receipt of a written request of
Indemnitee in accordance with Section 10 hereof. In all other cases,
indemnification shall be made by the Company only if authorized in the specific
case, upon a determination that indemnification of the Agent is proper under the
circumstances and the terms of this Agreement by:  (i) a majority vote of a
quorum of the Board of Directors (or a duly constituted committee thereof),
consisting of directors who are not parties to such Proceeding; (ii) if such a
quorum of directors is not obtainable, by Independent Legal Counsel;
(iii) approval of the shareholders, with Indemnitee's shares not being entitled
to vote thereon; or (iv) the court in which such Proceeding is or was pending
upon application made by the Company, Indemnitee or any person rendering
services in connection with Indemnitee's defense, whether or not the Company
opposes such application.

    If Indemnitee seeks to enforce his rights hereunder, the person or entity
making such determination shall presume that Indemnitee is entitled to
indemnification and the burden of proving that indemnification or advances are
not appropriate shall be on the Company.  Neither the failure of the Company
(including its Board of Directors or Independent Legal Counsel) to have made a
determination prior to the commencement of such action that indemnification or


                                          4

<PAGE>

advances are proper in the circumstances because Indemnitee has met the
Applicable Standard of conduct, nor an actual determination by the Company
(including its Board of Directors or Independent Legal Counsel) that Indemnitee
has not met such Applicable Standard of conduct, shall be a defense to the
action or create a presumption that Indemnitee has not met the Applicable
Standard of conduct. Indemnitee's Expenses incurred in connection with
successfully establishing his right to indemnification or advances, in whole or
in part, in any such Proceeding shall also be indemnified by the Company;
provided, however, that if Indemnitee is only partially successful, the Company
shall indemnify Indemnitee to the extent that Indemnitee has been partially
successful.

    The Company's obligations to advance expenses or provide indemnity
hereunder shall be deemed satisfied to the extent of any payments made by an
insurer on behalf of the Company or Indemnitee.

    7.   AGREEMENT TO BE LIBERALLY CONSTRUED.  The purpose of this Agreement is
to induce Indemnitee either to serve the Company in one or more of the
capacities described in Section 1.1 hereof, or to induce Indemnitee to continue
to serve in one or more such capacities. The Company acknowledges that, but for
this Agreement and the expectation by Indemnitee that the Company will perform
each and every one of its obligations hereunder, Indemnitee may not consent to
serve or to continue to serve the Company in such capacities.  Therefore, it is
the intention of the Company and Indemnitee that this Agreement be liberally
construed so as to achieve its purpose, subject to Section 9 hereof, of
protecting Indemnitee from and against Expenses, judgments, fines or penalties
arising from a Proceeding against Indemnitee in his capacity as Agent. The
Company agrees that it will not do or fail to do any act which might prevent or
hinder the performance by the Company of its obligations under this Agreement.
The Company agrees that its obligations hereunder will survive (A) any actual or
purported termination of this Agreement by the Company or its successors whether
by operation of law or otherwise, and (B) termination of the Indemnitee's
services to the Company, whether such services were terminated by the Company or
the Indemnitee, with respect to any Proceeding, whether or not such Proceeding
is made, threatened or commenced before or after the actual or purported
termination of this Agreement or the termination of the Indemnitee's services to
the Company.

    8.   AGREEMENT NOT EXCLUSIVE.  The indemnification provided by this
Agreement shall not be deemed exclusive of any other rights to which Indemnitee
may be entitled under the Articles of Incorporation, the Bylaws, any agreement,
any vote of shareholders or disinterested directors, the Delaware General
Corporation Law, or otherwise, both as to action or inaction in his official
capacity and as to action or inaction in another capacity while holding such
office.  The indemnification under this Agreement shall continue as to
Indemnitee even though he may have ceased to be an Agent and shall inure to the
benefit of the heirs, devisees, executors, administrators and other personal
representatives of Indemnitee.

    9.   LIMITATIONS.  The Company shall not be liable under this Agreement to
make any payment or advance in connection with any claim made against
Indemnitee:


                                          5

<PAGE>

         9.1  to the extent paid under an insurance policy;

         9.2  for which Indemnitee is indemnified by the Company otherwise than
pursuant to this Agreement;

         9.3  based upon or attributable to the Agent gaining in fact any
personal profit or advantage to which he was not legally entitled;

         9.4  for an accounting of profits made from the purchase or sale by
the Agent of securities of the Company within the meaning of Section 16(b) of
the Securities Exchange Act of 1934 and amendments thereto or similar provisions
of any state statutory law or common law; or

         9.5  for omissions or acts as to which indemnification is not
permitted under applicable law.

    10.  NOTICES.  Indemnitee shall give to the Company notice in writing
within 30 days after he becomes aware of any claim made against him for which he
believes, or should reasonably believe, indemnification will or could be sought
under this Agreement; provided, however, that the failure to so notify the
Company shall not relieve the Company of any liability which it may have to
Indemnitee (i) under this Agreement, unless the failure to so notify shall have
materially prejudiced the Company's rights hereunder and (ii) otherwise than
under this Agreement.

    All notices, requests, demands and other communications (collectively
"notices") provided for under this Agreement shall be in writing (including
communications by telephone, telex or telecommunication facilities providing
facsimile transmission) and mailed (postage prepaid and return receipt
requested), telegraphed, telexed, transmitted or personally served to the
Company at its main office, Attention: President, and to Indemnitee at the
address set forth at the end of this Agreement, or at such other address as any
party affected may designate in a written notice to the other parties in
compliance with this section.  All such notices shall be effective when
transmitted or personally delivered.

    No Expenses for which indemnity is sought hereunder shall be incurred
without the Company's consent, which consent shall not be unreasonably withheld.

    11.  CHOICE OF LAW.  This Agreement shall be interpreted and enforced in
accordance with the laws of the State of Delaware, including applicable statutes
of limitation and other procedural statutes.

    12.  CHOICE OF FORUM.  The Company and Indemnitee agree that any action
instituted by or on behalf of the Company, Indemnitee or any other person under
this Agreement or to enforce or interpret any provision of this Agreement shall
be brought only in the state courts of


                                          6

<PAGE>

the State of Delaware, and in no other court.  The parties agree, and will at
such time agree, to the exclusive jurisdiction and exclusive venue of such
court, and to personal service upon the Company and Indemnitee by such court for
the purpose of such action, and will not attempt to transfer or remove such
action to another court.

    13.  ATTORNEYS' FEES.  If any legal action is necessary to enforce the
terms of this Agreement, the prevailing party shall be entitled to recover, in
addition to other amounts to which the prevailing party may be entitled, actual
attorneys' fees and court costs as may be awarded by the court.

    14.  AMENDMENTS.  Provisions of this Agreement may be waived, altered,
amended or repealed in whole or in part only by the written consent of all
parties hereto.

    15.  PARTIES IN INTEREST.  Nothing in this Agreement, whether express or
implied, is intended to confer any rights or remedies under or by reason of this
Agreement to any persons other than the parties to it and their respective
successors and assigns (including the heirs, devisees, executors,
administrators or other legal representatives of Indemnitee), nor is anything in
this Agreement intended to relieve or discharge the obligation or liability of
any third persons to any party hereto. Furthermore, no provision of this
Agreement shall give any third persons any right of subrogation or action
against any party here to.

    16.  SEVERABILITY.  If any portion of this Agreement shall be deemed by a
court of competent jurisdiction to be unenforceable, the remaining portions
shall be valid and enforceable. If this Agreement or any portion hereof is
invalidated on any ground by any court of competent jurisdiction, then the
Company shall nevertheless indemnify Indemnitee as to Expenses with respect to
any Proceeding to the fullest extent permitted by any applicable portion of this
Agreement by any other applicable law.

    17.  SUCCESSORS AND ASSIGNS.  All terms and conditions of this Agreement
shall be binding upon and shall inure to the benefit of the parties and their
respective transferees, successors and assigns, including without limitation the
heirs, devisees, executors, administrators or other legal representatives of
Indemnitee; provided, however, that this Agreement and all rights, privileges,
duties and obligations of the parties, may not be assigned or delegated by any
party without the prior written consent of the other parties.

    18.  COUNTERPARTS.  This  Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

    19.  ENTIRE AGREEMENT.  Except as provided in Section 8 hereof, this
Agreement represents and contains the entire agreement and understanding between
and among the parties, and all previous statements or understandings, whether
express or implied, oral or written, relating to the subject matter hereof are
fully and completely extinguished and superseded by this

Agreement.  This Agreement shall not be altered or varied except by a writing
signed by all of the parties hereto.

    IN WITNESS WHEREOF, the undersigned have executed this Agreement as of the
date first above written.

                       ADVANCED AERODYNAMICS & STRUCTURES, INC.
                                1996 STOCK OPTION PLAN

    1.   PURPOSE.  This Stock Option Plan (the "Plan") is intended to serve as
an incentive to, and to encourage stock ownership by, certain eligible
participants rendering services to Advanced Aerodynamics & Structures, Inc., a
Delaware corporation, and certain affiliates as set forth below (the
"Corporation"), so that they may acquire or increase their proprietary interest
in the Corporation and to encourage them to remain in the service of the
Corporation.

    2.   ADMINISTRATION.

         2.1  COMMITTEE.  The Plan shall be administered by a committee of one
or more outside directors appointed by the Board of Directors of the Corporation
(the "Committee").  The Committee shall select one of its members as Chairman
and shall appoint a Secretary, who need not be a member of the Committee.  The
Committee shall hold meetings at such times and places as it may determine and
minutes of such meetings shall be recorded.  Acts by a majority of the Committee
in a meeting at which a quorum is present and acts approved in writing by a
majority of the members of the Committee shall be valid acts of the Committee.

         2.2  FORMULA GRANTS TO NON-EMPLOYEE DIRECTORS.  Notwithstanding the
other provisions of this Plan regarding the grant of options, options shall be
granted to non-employee Directors of the Corporation as follows:

              2.2.1     Options to acquire 25,000 shares of Stock (as defined
below) shall be granted to each such Director of the Corporation within six
months after taking office as a member of the Board of Directors of the
Corporation.  Such options shall vest and become exercisable in 5,000 share
intervals on each anniversary of the date of grant commencing on the first such
anniversary.

              2.2.2     The exercise price for options granted pursuant to this
Section 2.2 shall be the fair market value of the Stock, as determined by the
Committee, on the date of grant, unless a higher price is required by applicable
securities or tax laws.

              2.2.3     This Section 2.2 shall not be modified more often than
once every six months, except as may be necessary or advisable to comport with
the requirements of any applicable law or regulation.

         2.3  TERM.  If the Board of Directors selects a Committee, the members
of the Committee shall serve on the Committee for the period of time determined
by the Board of Directors and shall be subject to removal by the Board of
Directors at any time.  The Board of Directors may terminate the function of the
Committee at any time and resume all powers and authority previously delegated
to the Committee.


<PAGE>

         2.4  AUTHORITY.  The Committee shall have sole discretion and
authority to grant options under the Plan to eligible participants rendering
services to the Corporation or any "parent" or "subsidiary" of the Corporation,
as defined in Section 424 of the Internal Revenue Code of 1986, as amended (the
"Code") ("Parent or Subsidiary"), at such times, under such terms and in such
amounts as it may decide.  For purposes of this Plan and any Stock Option
Agreement (as defined below), the term "Corporation" shall include any Parent or
Subsidiary, if applicable.  Subject to the express provisions of the Plan, the
Committee shall have complete authority to interpret the Plan, to prescribe,
amend and rescind the rules and regulations relating to it, to determine the
details and provisions of any Stock Option Agreement, to accelerate any options
and to make all other determinations necessary and advisable for the
administration of the Plan.

         2.5  TYPE OF OPTION.  The Committee shall have full authority and
discretion to determine, and shall specify, whether the eligible individual will
be granted options intended to qualify as incentive options under Section 422 of
the Code ("Incentive Options") or options which are not intended to qualify
under Section 422 of the Code ("Non-Qualified Options"); provided, however, that
Incentive Options shall only be granted to employees of the Corporation, or a
Parent or Subsidiary thereof, and shall be subject to the special limitations
set forth herein attributable to Incentive Options.

         2.6  INTERPRETATION.  The interpretation and construction by the
Committee of any provisions of the Plan or of any option granted under the Plan
shall be final and binding on all parties having an interest in the Plan or any
option granted hereunder.  No member of the Committee shall be liable for any
action or determination made in good faith with respect to the Plan or any
option granted under the Plan.

    3.   ELIGIBILITY.

         3.1  GENERAL.  All directors, officers, employees of and certain
persons rendering services to the Corporation relative to the Corporation's
management, operation or development shall be eligible to receive options under
the Plan.  The selection of recipients of options shall be within the sole and
absolute discretion of the Committee.  No person shall be granted an Incentive
Option under this Plan unless such person is an employee of the Corporation on
the date of grant.  No person shall be granted an option under this Plan unless
such person has executed the grant representation letter set forth on
Exhibit "A," as such Exhibit may be amended by the Committee from time to time.


                                          2

<PAGE>


         3.2  TERMINATION OF ELIGIBILITY.

              3.2.1     If an optionee ceases to be employed by the
Corporation, is no longer an officer or member of the Board of Directors of the
Corporation, or no longer performs services for the Corporation for any reason
(other than for "cause," as hereinafter defined, or such optionee's death), any
vested option granted hereunder to such optionee shall expire on the 90th day
after the occurrence giving rise to such termination of eligibility (or 1 year
in the event an optionee is "disabled," as defined in Section 22(e)(3) of the
Code) or upon the date it expires by its terms, whichever is earlier.  Any
option that has not vested in the optionee as of the date of such termination
shall immediately expire and shall be null and void.  The Committee shall, in
its sole and absolute discretion, decide whether an authorized leave of absence
or absence for military or governmental service, or absence for any other
reason, shall constitute termination of eligibility for purposes of this
Section.

              3.2.2     If an optionee ceases to be employed by the
Corporation, is no longer an officer or member of the Board of Directors of the
Corporation, or no longer performs services for the Corporation and such
termination is as a result of "cause," as hereinafter defined, then all options
granted hereunder to such optionee shall expire on the date of the occurrence
giving rise to such termination of eligibility or upon the date it expires by
its terms, whichever is earlier, and such optionee shall have no rights with
respect to any unexercised options.  For purposes of this Plan, "cause" shall
mean an optionee's personal dishonesty, misconduct, breach of fiduciary duty,
incompetence, intentional failure to perform stated obligations, willful
violation of any law, rule, regulation or final cease and desist order, or any
material breach of any provision of this Plan, any Stock Option Agreement or any
employment agreement.

         3.3  DEATH OF OPTIONEE AND TRANSFER OF OPTION.  In the event an
optionee shall die, an option may be exercised (subject to the condition that no
option shall be exercisable after its expiration and only to the extent that the
optionee's right to exercise such option had accrued at the time of the
optionee's death) at any time within six months after the optionee's death by
the executors or administrators of the optionee or by any person or persons who
shall have acquired the option directly from the optionee by bequest or
inheritance.  Any option that has not vested in the optionee as of the date of
death or termination of employment, whichever is earlier, shall immediately
expire and shall be null and void.  No option shall be transferable by the
optionee other than by will or the laws of intestate succession.

         3.4  LIMITATION ON INCENTIVE OPTIONS.  No person shall be granted any
Incentive Option to the extent that the aggregate fair market value of the Stock
(as defined below) to which such options are exercisable for the first time by
the optionee during any calendar year (under all plans of the Corporation as
determined under Section 422(d) of the Code) exceeds $100,000.


                                          3

<PAGE>

         3.5  LIMITATION ON NUMBER OF OPTIONS.  No person shall be granted in
any calendar year options to acquire more than 50,000 shares of Stock.

    4.   IDENTIFICATION OF STOCK.  The Stock, as defined herein, subject to the
options shall be shares of the Corporation's authorized but unissued or acquired
or reacquired Class A Common Stock (the "Stock").  The aggregate number of
shares subject to outstanding options shall not exceed 500,000 shares of Stock
(subject to adjustment as provided in Section 6).  If any option granted
hereunder shall expire or terminate for any reason without having been exercised
in full, the unpurchased shares subject thereto shall again be available for
purposes of this Plan.

    5.   TERMS AND CONDITIONS OF OPTIONS.  Any option granted pursuant to the
Plan shall be evidenced by an agreement ("Stock Option Agreement") in such form
as the Committee shall from time to time determine, which agreement shall comply
with and be subject to the following terms and conditions:

         5.1  NUMBER OF SHARES.  Each option shall state the number of shares
of Stock to which it pertains.

         5.2  OPTION EXERCISE PRICE.  Each option shall state the option
exercise price, which shall be determined by the Committee; provided, however,
that (i) the exercise price of any Incentive Option shall not be less than the
fair market value of the Stock, as determined by the Committee, on the date of
grant of such option, (ii) the exercise price of any Incentive Option granted to
an employee who owns more than 10% of the total combined voting power of all
classes of the Corporation's stock, as determined for purposes of Section 422 of
the Code, shall not be less than 110% of the fair market value of the Stock, as
determined by the Committee, on the date of grant of such option, and (iii) the
exercise price of any Non-Qualified Option shall not be less than the fair
market value of the Stock, as determined by the Committee, on the date of grant
of such option.

         5.3  TERM OF OPTION.  The term of an option granted hereunder shall be
determined by the Committee at the time of grant, but shall not exceed ten years
from the date of the grant.  The term of any Incentive Option granted to an
employee who owns more than 10% of the total combined voting power of all
classes of the Corporation's stock, as determined for purposes of Section 422 of
the Code, shall in no event exceed five years from the date of grant.  All
options shall be subject to early termination as set forth in this Plan.  In no
event shall any option be exercisable after the expiration of its term.

         5.4  METHOD OF EXERCISE.  An option shall be exercised by written
notice to the Corporation by the optionee (or successor in the event of death)
and execution by the optionee of an exercise representation letter in the form
set forth on Exhibit "B," as such Exhibit may be amended by the Committee from
time to time.  Such written notice shall state the number of shares with respect
to which the option is being exercised and designate a time, during normal


                                          4

<PAGE>

business hours of the Corporation, for the delivery thereof ("Exercise Date"),
which time shall be at least 30 days after the giving of such notice unless an
earlier date shall have been mutually agreed upon.  At the time specified in the
written notice, the Corporation shall deliver to the optionee at the principal
office of the Corporation, or such other appropriate place as may be determined
by the Committee, a certificate or certificates for such shares.
Notwithstanding the foregoing, the Corporation may postpone delivery of any
certificate or certificates after notice of exercise for such reasonable period
as may be required to comply with any applicable listing requirements of any
securities exchange.  In the event an option shall be exercisable by any person
other than the optionee, the required notice under this Section shall be
accompanied by appropriate proof of the right of such person to exercise the
option.

         5.5  MEDIUM AND TIME OF PAYMENT.  The option exercise price shall be
payable in full on or before the option Exercise Date in any one of the
following alternative forms:

              5.5.1     Full payment in cash or certified bank or cashier's
check;

              5.5.2     A Promissory Note (as defined below);

              5.5.3     Full payment in shares of Stock or other securities of
the Corporation having a fair market value on the Exercise Date in the amount
equal to the option exercise price;

              5.5.4     A combination of the consideration set forth in
Sections 5.4.1, 5.4.2 and 5.4.3 equal to the option exercise price; or

              5.5.5     Any other method of payment complying with the
provisions of Section 422 of the Code with respect to Incentive Options,
provided the terms of payment are established by the Committee at the time of
grant and any other method of payment established by the Committee with respect
to Non-Qualified Options.

    5.6  FAIR MARKET VALUE.  The fair market value of a share of Stock on any
relevant date shall be determined in accordance with the following provisions:

              5.6.1     If the Stock or other security of the Corporation at
the time is neither listed nor admitted to trading on any stock exchange nor
traded in the over-the-counter market, then the fair market value shall be
determined by the Committee after taking into account such factors as the
Committee shall deem appropriate.

              5.6.2     If the Stock or other security of the Corporation is
not at the time listed or admitted to trading on any stock exchange but is
traded in the over-the-counter market, the fair market value shall be the mean
between the highest bid and lowest asked prices (or, if such information is
available, the closing selling price) of one share of Stock or other security of
the Corporation on the date in question in the over-the-counter market, as such
prices


                                          5

<PAGE>

are reported by the National Association of Securities Dealers through its
NASDAQ system or any successor system.  If there are no reported bid and asked
prices (or closing selling price) for the Stock or other security of the
Corporation on the date in question, then the mean between the highest bid price
and lowest asked price (or the closing selling price) on the last preceding date
for which such quotations exist shall be determinative of fair market value.

              5.6.3     If the Stock or other security of the Corporation is at
the time listed or admitted to trading on any stock exchange, then the fair
market value shall be the closing selling price of one share of Stock or other
security of the Corporation on the date in question on the stock exchange
determined by the Committee to be the primary market for the Stock or other
security of the Corporation, as such price is officially quoted in the composite
tape of transactions on such exchange.  If there is no reported sale of Stock or
other security of the Corporation on such exchange on the date in question, then
the fair market value shall be the closing selling price on the exchange on the
last preceding date for which such quotation exists.

         5.7  PROMISSORY NOTE.  Subject to the requirements of applicable state
or Federal law or margin requirements, and if provided in the Stock Option
Agreement, payment of all or part of the purchase price of the Stock may be made
by delivery of a full recourse promissory note ("Promissory Note").  The
Promissory Note shall be executed by the optionee, made payable to the
Corporation and bear interest at such rate as the Committee shall determine, but
in no case less than the minimum rate which will not cause under the Code (i)
interest to be imputed, (ii) original issue discount to exist, or (iii) any
other similar results to occur.  Unless otherwise determined by the Committee,
interest on the Note shall be payable in quarterly installments on March 31,
June 30, September 30 and December 31 of each year.  A Promissory Note shall
contain such other terms and conditions as may be determined by the Committee;
provided, however, that the full principal amount of the Promissory Note and all
unpaid interest accrued thereon shall be due not later than five years from the
date of exercise.  The Corporation may obtain from the optionee a security
interest in all shares of Stock issued to the optionee under the Plan for the
purpose of securing payment under the Promissory Note and may retain possession
of the stock certificates representing such shares in order to perfect its
security interest.

         5.8  RIGHTS AS A SHAREHOLDER.  An optionee or successor shall have no
rights as a shareholder with respect to any Stock underlying any option until
the date of the issuance to such optionee of a certificate for such Stock.  No
adjustment shall be made for dividends (ordinary or extraordinary, whether in
cash, securities or other property) or distributions or other rights for which
the record date is prior to the date such Stock certificate is issued, except as
provided in Section 6.

         5.9  MODIFICATION, EXTENSION AND RENEWAL OF OPTIONS.  Subject to the
terms and conditions of the Plan, the Committee may modify, extend or renew
outstanding options granted under the Plan, or accept the surrender of
outstanding options (to the extent not exercised) and authorize the granting of
new options in substitution therefor.

         5.10  VESTING AND RESTRICTIONS.  The Committee shall have complete
authority and discretion to set the terms, conditions, restrictions, vesting
schedules and other provisions of any option in the applicable Stock Option
Agreement.  In addition, the Committee shall have complete authority to require
conditions and restrictions on any Stock issued pursuant to this Plan.

         5.11  OTHER PROVISIONS.  The Stock Option Agreements shall contain
such other provisions as the Committee shall deem advisable.

    6.   ADJUSTMENTS UPON CHANGES IN CAPITALIZATION.

         6.1  SUBDIVISION OR CONSOLIDATION.  Subject to any required action by
shareholders of the Corporation, the number of shares of Stock covered by each
outstanding option, and the exercise price thereof, shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Stock of
the Corporation resulting from a subdivision or consolidation of shares or the
payment of a stock dividend (but only on the Stock) or any other increase or
decrease in the number of such shares effected without receipt of consideration
by the Corporation.  Any fraction of a share subject to option that would
otherwise result from an adjustment pursuant to this Section shall be rounded
downward to the next full number of shares without other compensation or
consideration to the holder of such option.

         6.2  CAPITAL TRANSACTIONS.  Upon a sale or exchange of all or
substantially all of the assets of the Corporation, a merger or consolidation in
which the Corporation is not the surviving corporation, a merger, reorganization
or consolidation in which the Corporation is the surviving corporation and
shareholders of the Corporation exchange their stock for securities or property,
a liquidation of the Corporation, or similar transaction ("Capital
Transaction"), this Plan and each option issued under this Plan, whether vested
or unvested, shall terminate, unless such options are assumed by a successor
corporation in a merger or consolidation or otherwise determined by the
Committee, 15 days prior to such Capital Transaction; provided, however, that
unless the outstanding options are assumed by a successor corporation in a
merger or consolidation, subject to terms approved by the Committee, all
optionees will have the right, until 15 days prior to such Capital Transaction,
to exercise all vested options.  Notwithstanding the foregoing, in the event
there is a merger or consolidation where the Corporation is not the surviving
corporation, all options granted under this Plan shall vest 30 days prior to
such merger or consolidation unless such options are assumed by the successor
corporation in such merger or consolidation.  The Committee may (but shall not
be obligated to) (i)  accelerate the vesting of any option or (ii) apply the
foregoing provisions, including but not limited to termination of this Plan and
options granted pursuant to the Plan, in the event there is a sale of 51% or
more of the stock of the Corporation in any two year period or a transaction
similar to a Capital Transaction.

         6.3  ADJUSTMENTS.  To the extent that the foregoing adjustments relate
to stock or securities of the Corporation, such adjustments shall be made by the
Committee, whose determination in that respect shall be final, binding and
conclusive.


                                          7

<PAGE>


         6.4  ABILITY TO ADJUST.  The grant of an option pursuant to the Plan
shall not affect in any way the right or power of the Corporation to make
adjustments, reclassifications, reorganizations or changes of its capital or
business structure or to merge, consolidate, dissolve, liquidate, sell or
transfer all or any part of its business or assets.

         6.5  NOTICE OF ADJUSTMENT.  Whenever the Corporation shall take any
action resulting in any adjustment provided for in this Section, the Corporation
shall forthwith deliver notice of such action to each optionee, which notice
shall set forth the number of shares subject to the option and the exercise
price thereof resulting from such adjustment.

         6.6  LIMITATION ON ADJUSTMENTS.  Any adjustment, assumption or
substitution of an Incentive Option shall comply with Section 425 of the Code,
if applicable.

    7.   NONASSIGNABILITY.  Options granted under this Plan may not be sold,
pledged, assigned or transferred in any manner other than by will or by the laws
of intestate succession, and may be exercised during the lifetime of the
optionee only by such optionee.  Any transfer in violation of this provision
shall void such option, and any Stock Option Agreement entered into by the
optionee and the Corporation regarding such option shall be void and have no
further force or effect.  No option shall be pledged or hypothecated in any way,
nor shall any option be subject to execution, attachment or similar process.

    8.   NO RIGHT OF EMPLOYMENT.  Neither the grant nor exercise of any option
nor anything in this Plan shall impose upon the Corporation or any other
corporation any obligation to employ or continue to employ any optionee.  The
right of the Corporation and any other corporation to terminate any employee
shall not be diminished or affected because an option has been granted to such
employee.

    9.   TERM OF PLAN.  This Plan is effective on the date the Plan is adopted
by the Board of Directors and options may be granted pursuant to the Plan from
time to time within a period of ten (10) years from such date, or the date of
any required shareholder approval required under the Plan, if earlier.
Termination of the Plan shall not affect any option theretofore granted.

    10.  AMENDMENT OF THE PLAN.  The Board of Directors of the Corporation may,
subject to any required shareholder approval, suspend, discontinue or terminate
the Plan, or revise or amend it in any respect whatsoever with respect to any
shares of stock at that time not subject to options.

    11.  APPLICATION OF FUNDS.  The proceeds received by the Corporation from
the sale of Stock pursuant to options may be used for general corporate
purposes.

    12.  RESERVATION OF SHARES.  The Corporation, during the term of this Plan,
shall at all times reserve and keep available such number of shares of Stock as
shall be sufficient to satisfy the requirements of the Plan.


                                          8

<PAGE>


    13.  NO OBLIGATION TO EXERCISE OPTION.  The granting of an option shall not
impose any obligation upon the optionee to exercise such option.

    14.  APPROVAL OF BOARD OF DIRECTORS AND SHAREHOLDERS.  The Plan shall not
take effect until approved by the Board of Directors of the Corporation.  This
Plan shall be approved by a vote of the shareholders within 12 months from the
date of approval by the Board of Directors.  In the event such shareholder vote
is not obtained, all options granted hereunder, whether vested or unvested,
shall be null and void.

    15.  WITHHOLDING TAXES.  Notwithstanding anything else to the contrary in
this Plan or any Stock Option Agreement, the exercise of any option shall be
conditioned upon payment by such optionee in cash, or other provisions
satisfactory to the Committee, of all local, state, federal or other withholding
taxes applicable, in the Committee's judgment, to the exercise or to later
disposition of shares acquired upon exercise of an option (including any
repurchase of an option or Stock).

    16.  PARACHUTE PAYMENTS.  Any outstanding option under the Plan may not be
accelerated to the extent any such acceleration of such option would, when added
to the present value of other payments in the nature of compensation which
becomes due and payable to the optionee would result in the payment to such
optionee of an excess parachute payment under Section 280G of the Code.  The
existence of any such excess parachute payment shall be determined in the sole
and absolute discretion of the Committee.

    17.  SECURITIES LAWS COMPLIANCE.  Notwithstanding anything contained
herein, the Corporation shall not be obligated to grant any option under this
Plan or to sell, issue or effect any transfer of any Stock unless such grant,
sale, issuance or transfer is at such time effectively (i) registered or exempt
from registration under the Securities Act of 1933, as amended (the "Act"), and
(ii) qualified or exempt from qualification under the California Corporate
Securities Law of 1968 and any other applicable state securities laws.  As a
condition to exercise of any option, each optionee shall make such
representations as may be deemed appropriate by counsel to the Corporation for
the Corporation to use any available exemption from registration under the Act
or qualification under any applicable state securities law.

    18.  RESTRICTIVE LEGENDS.  The certificates representing the Stock issued
upon exercise of options granted pursuant to this Plan will bear the following
legends giving notice of restrictions on transfer under the Act and this Plan,
as follows:

         (a)  THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ISSUED
              OR TRANSFERRED IN A TRANSACTION WHICH WAS NOT REGISTERED
              UNDER THE SECURITIES ACT OF 1933, AS AMENDED, IN RELIANCE

              OF THESE SHARES SHALL

              ISSUER SHALL NOT BE REQUIRED TO GIVE ANY EFFECT TO ANY SUCH
              TRANSACTION UNLESS (A) SUCH TRANSACTION SHALL HAVE BEEN DULY
              REGISTERED UNDER THE ACT OR (B) THE ISSUER SHALL HAVE FIRST
              RECEIVED AN OPINION OF COUNSEL SATISFACTORY TO IT THAT SUCH
              REGISTRATION IS NOT REQUIRED.

         (b)  Any other legends required by applicable state securities laws as
              determined by the Committee.

    19.  NOTICES.  Any notice to be given under the terms of the Plan shall be
addressed to the Corporation in care of its Secretary at its principal office,
and any notice to be given to an optionee shall be addressed to such optionee at
the address maintained by the Corporation for such person or at such other
address as the optionee may specify in writing to the Corporation.

    As adopted by the Board of Directors on July 16, 1996.

remedies available to it at law, in equity or as set forth in this Agreement,
the Company shall have the right, upon written notice to the Employee, to
immediately terminate his employment (a "Termination With Cause") hereunder,
without any further liability or obligation to him hereunder or otherwise in
respect of his employment, other than its obligation to pay accrued but unpaid
Base Salary and vacation time as of the date of termination.  If the Employee
resigns, this Agreement shall  immediately terminate and the Company shall have
no further liability or obligation to Employee hereunder or otherwise in respect
of his employment, other than its obligation to pay accrued but unpaid Base
Salary and vacation time as of the date of resignation.

    4.02  TERMINATION OF EMPLOYMENT WITHOUT CAUSE.  Notwithstanding any
provision to the contrary herein, the Company may at any time, in its sole and
absolute discretion and for any or no reason, terminate the employment of the
Employee hereunder; PROVIDED, that if such termination is not a Termination With
Cause, the Company shall pay and/or provide the Employee as follows:

         (a)  any accrued but unpaid Base Salary as of the date of  the
termination as and when such amount is due and payable hereunder.

         (b)  provided Employee has not accepted employment with another
employer (as provided below), Employer shall pay monthly to Employee one-twelfth
(1/12) of the Base Salary in effect as of the date of such termination (the
"Severance Payments") for a period not to exceed the lesser of (i) the remainder
of the initial term of this Agreement or (ii) eighteen months (the "Severance
Period"), with the first payment being made on the thirtieth (30th) day
following such date of


                                          2

<PAGE>

termination and with each subsequent payment being made on the same day of each
successive month.  The obligation of the Company to provide the Benefits shall
continue for six months following the date of such termination without cause,
PROVIDED, that the Company may, at its option,  pay for and acquire insurance
which will provide to Employee the Benefits for the duration of the Severance
Period.

    Notwithstanding the foregoing paragraph (b), the Severance Period,
Severance Payments and the provision of Benefits shall terminate when (i) the
Employee has secured new employment with a base salary equal to or greater than
the Base Salary in effect as of the date of termination or (ii) the Employee
enters into direct or indirect competition with Employer, as set forth in
Section 5.03.  If the Employee accepts new employment with a base salary (the
"New Salary") less than the Base Salary in effect as of the date of termination
and the Severance Period set forth above has not expired, the Company, in lieu
of the remaining Severance Payments to be made, shall pay the Employee the
difference between the total amount of the remaining Severance Payments due and
the total amount of New Salary payable during the remaining applicable Severance
Period.

    (c)  a cash payment immediately upon the date of termination equal to the
Employee's Base Salary on a daily basis (computed on a 260 workday year) in
effect on the date of termination multiplied by the number of accrued and unused
vacation days at the date of termination.

    (d)  Notwithstanding the foregoing, if any amounts due to Employee pursuant
to this Agreement are determined to be "Parachute Payments" as such term is
defined in Section 280G of the Internal Revenue Code of 1986, as amended (the
"Code"), and the regulations promulgated thereunder, then the total compensation
paid to Employee pursuant to this Agreement, together with any other payment or
the value of any benefit received or to be received by the Employee which is
treated as a Parachute Payment shall not exceed 2.99 times the Employee's Base
Amount (as such term is defined in Section 280G of the Code).  In the event a
reduction of the payments set forth in this Agreement is required pursuant to
this Section, the Employee may select the compensation which will be reduced in
order to fall within the 2.99 times Base Amount limitation.

    4.03  DEATH; DISABILITY.  The Employee's employment hereunder shall
terminate (x) upon his death or (y) if the Employee becomes Disabled (as such
term is hereinafter defined), at the election of the Company by written notice
to the Employee.  In the event of a termination of the Employee's employment for
death or Disability, the Company shall pay the Employee (or his legal
representatives, as the case may be) as follows:

         (a)  any accrued but unpaid compensation for Base Salary as of the
date of death or termination for Disability, as and when such amounts are due
and payable hereunder;

         (b)  a cash payment payable on the date of termination equal to the
Employee's Base Salary on a daily basis (computed on a 260 workday year) in
effect on the date of death or termination, multiplied by the number of accrued
and unused vacation days at the date of such termination; and


                                          3

<PAGE>

         (c)  in the event the Employee is Disabled, the Company will continue
to pay Base Salary and Benefits for the Employee for a period of six (6) months,
until and unless the Employee obtains other employment with a comparable base
salary within such period, PROVIDED, that the Company may, at its option, pay
for and acquire insurance which will provide to Employee the Base Salary and
Benefits for the duration of the Severance Period.

    For the purpose of this Agreement, the Employee shall be deemed to be
"Disabled" or have a "Disability" if he has been unable to perform his duties
hereunder for three (3) consecutive months or ninety (90) days in any twelve
(12) consecutive month period, as determined in good faith by the Board of
Directors of the Company.

    The Employee acknowledges that the payments referred to in this 
Section 4.03 constitute the only payments to which the Employee (or his legal
representatives, as the case may be) shall be entitled to receive from the
Company hereunder in the event of a termination of his employment for death or
Disability, and that except for such payments the Company shall have no further
liability or obligation to him (or his legal representatives, as the case may
be) hereunder or otherwise in respect of his employment.

Company and shall be promptly and fully disclosed by the Employee to the
Company.  The Employee shall perform all necessary acts (including, without
limitation, executing and delivering any confirmatory assignments, documents or
instruments requested by the Company) to vest title to any such Inventions in
the Company and to enable the Company, at its expense, to secure and maintain
domestic and/or foreign patents or any other rights for such Inventions.

    5.02  NON-DISCLOSURE.  The Employee shall not, at any time during the Term

procedure used by the Company which is not, specifically, a matter of public
knowledge; or (b) any information relating to the operations or financial status
of the Company (including, without limitation, all financial data and sources of
financing), which information is not specifically a matter of public knowledge;
or (c) any information of a confidential nature obtained as a result of his
present or future relationship with the Company, which information is not
specifically a matter of public knowledge; or (d) the name, address or other
information relating to any customer or supplier


                                          4

<PAGE>

of the Company; or (e) any other trade secrets of the Company.  Promptly upon
the expiration or termination of the Employee's employment hereunder for any
reason, the Employee (or his personal representative's as the case may be) shall
surrender to the Company all documents, drawings, work papers, lists, memoranda,
records and other data (including all copies) constituting or pertaining in any
way to any of the foregoing information.

    5.03  NON-SOLICITATION.  The Employee shall not, during the Term, and for
an eighteen (18) month period following the date of a resignation by Employee or
a Termination With Cause or without cause, interfere with or disrupt or attempt
to disrupt Employer's business relationship with its customers or suppliers or
solicit any of the employees of Employer to leave the employ of Employer.

    5.04  NON-COMPETITION.  Upon the termination of this Agreement pursuant to
the terms hereof or pursuant to any right of cancellation or termination
provided herein, or for any other reason whatsoever, Employee will not engage in
any business in competition with that of Employer within any state or territory
of the United States in which Employer is doing business or has actually
investigated doing business, nor directly or indirectly perform services for any
person, firm or corporation engaged in such a competitive business in such
territory for a period of eighteen (18) months following such termination of
employment.

    5.05  BREACH OF PROVISIONS.  If the Employee breaches any of the provisions
of this Article V, or in the event that any such breach is threatened by the
Employee, in addition to and without limiting or waiving any other remedies
available to the Company at law or in equity, the Company shall be entitled to
immediate injunctive relief in any court, domestic or foreign, having the
capacity to grant such relief, to restrain any such breach or threatened breach
and to enforce the provisions of this Article V.  The Employee acknowledges and
agrees that there is no adequate remedy at law for any such breach or threatened
breach and, in the event that any action or proceeding is brought seeking
injunctive relief, the Employee shall not use as a defense thereto that there is
an adequate remedy at law.

    5.06  REASONABLE RESTRICTIONS.  The parties acknowledge that the foregoing
restrictions,  as well as the duration and the territorial scope thereof as set
forth in this Article V, are under all of the circumstances reasonable and
necessary for the protection of the Company and its business.

    5.07  DEFINITION.  For purposes of this Article V, the term "Company" shall

                                 AGREEMENT OF MERGER


    AGREEMENT OF MERGER ("Agreement"), dated as of this 16th day of July, 1996,
pursuant to Section 252 of the General Corporation Law of Delaware, between
Advanced Aerodynamics and Structures, Inc., a Delaware corporation ("AASI
Delaware"), and Advanced Aerodynamics and Structures, Inc, a California
corporation ("AASI California").

    WHEREAS, AASI California desires to reincorporate under the laws of the
State of Delaware through merger into a newly-formed Delaware corporation

    NOW THEREFORE, the corporations, parties to this Agreement, in
consideration of their respective covenants and promises set forth in this
Agreement do hereby agree and prescribe the terms and conditions of said merger
and mode of carrying the same into effect as follows:


    FIRST:  As of the effective date hereof, AASI Delaware (the "Surviving
Corporation") hereby merges with AASI California (the "Merged Corporation") and
the Merged Corporation shall be and hereby is merged into the Surviving
Corporation which shall be the surviving corporation.


    SECOND:  The Certificate of Incorporation of the Surviving Corporation, in
effect on the date of the merger provided for in this Agreement, shall continue
in full force and effect as the Certificate of Incorporation of the corporation
surviving this merger.


    THIRD:  The manner of converting the outstanding shares of the capital
stock of the merged Corporation into the shares of the Surviving Corporation
shall be as follows:


    (a)   As of the effective date of this merger, each share of the issued and
outstanding common and preferred stock of the Merged Corporation shall be
converted into .278729717 shares of the common stock of the Surviving
Corporation, 20% of which shall be shares of Class B Common Stock, 40% of which
shall be shares of Class E-1 Common Stock, and 40% of which shall be shares of
Class E-2 Common Stock of the Surviving Corporation.


<PAGE>

    (b)   After the effective date of this merger, each holder of an
outstanding certificate representing shares of common or preferred stock of the
Merged Corporation shall surrender the same to the Surviving Corporation and
each such holder shall be entitled upon such surrender to receive one or more
certificates evidencing the number of shares of common stock of the Surviving
Corporation provided for in this Agreement.  Until so surrendered, any
certificates evidencing previously outstanding shares of the stock of the Merged
Corporation to be converted into the stock of the Surviving Corporation as
provided herein, may be treated by the Surviving Corporation for all corporate
purposes as evidencing the ownership of shares of the Surviving Corporation as
though said surrender and exchange had taken place.


    FOURTH:  The terms and conditions of the merger are as follows:

    (a)   The Bylaws of the Surviving Corporation as they shall exist on the
effective date of this merger shall be and remain the bylaws of the Surviving
Corporation until the same shall be altered, amended or repealed as therein
provided.

    (b)   The directors and officers of the Surviving Corporation shall
continue in office until the next annual meeting of stockholders and until their
successors shall have been elected and qualified.

    (c)   This merger shall become effective upon filing of a Certificate of
Merger with the Secretary of State of Delaware.

    (d)   Upon the merger becoming effective, the separate corporate existence
of the Merged Corporation shall cease, and the Surviving Corporation shall
possess all of the rights, privileges, powers and franchises of the Merged
Corporation of a public as well as a private nature, and be subject to all of
the restrictions, disabilities, liabilities and duties of the Merged
Corporation; all of the rights, privileges, powers and franchises of the Merged
Corporation, and




                                          2

<PAGE>

all property, real, personal and mixed, and all debts due to the Merged
Corporation on whatever account, as well as all other things in action or
belonging to the Merged Corporation shall be vested in the Surviving
Corporation; and all property, rights, privileges, powers and franchises, and
all other interests of the Merged Corporation shall be thereafter the property
of the Surviving Corporation.  All corporate acts, plans, policies, agreements,
arrangements, approvals and authorizations of the Merged Corporation, its
shareholders, Board of Directors and committees thereof, officers and agents
which were valid and effective immediately prior to the effective date of the
merger, shall be taken for all purposes as the acts, plans, policies,
agreements, arrangements, approval and authorizations of the Surviving
Corporation, and shall be as effective and binding thereon as the same were with
respect to the Merged Corporation.  The employees and agents of the Merged
Corporation shall become the employees and agents of the Surviving Corporation.
From and after the effective date of the merger, the Surviving Corporation shall
consent to service of process within the State of California in any proceeding
for enforcement of any obligation of the Merged Corporation, as well as for
enforcement of any obligation of the Merged Corporation arising from the merger,
and shall irrevocably appoint the Secretary of State of California as its agent
to accept service of process in any such suit or other proceeding.

    FIFTH:  Anything herein or elsewhere to the contrary notwithstanding, this
Agreement may be terminated and abandoned by the Board of Directors of any
constituent corporation at any time prior to the date of filing the Certificate
of Merger Agreement with the Secretary of State of the State of Delaware.
