                         Notes to Financial Statements
                                  (unaudited)

1.  GENERAL

In the opinion of the Company's management, the accompanying unaudited financial
statements include all adjustments (which include only normal recurring
adjustments) necessary for a fair presentation of the financial position of the
Company at September 30, 1999 and the results of operations and cash flows for
the nine months ended September 30, 1999 and September 30, 1998 respectively and
for the period from January 26, 1990 to September 30, 1999.  Although the
Company believes that the disclosures in these financial statements are adequate
to make the information presented not misleading, certain information and
footnote disclosures normally included in financial statements prepared in
accordance with generally accepted accounting  principles have been condensed or
omitted pursuant to the rules and regulations of the Securities and Exchange
Commission. Results of operations for interim periods are not necessarily
indicative of results of operations to be expected for any other interim period
or the full year.

The financial information in this quarterly report should be read in conjunction
with the audited December 31, 1998 financial statements and notes thereto
included in the Company's annual report filed on Form 10-KSB.

The Company is a development stage enterprise. On December 3, 1996, the Company
successfully completed an initial public offering to finance the continued
development, manufacture and marketing of its product to achieve commercial
viability. The net proceeds of the offering were and will be used to amend its
Federal Aviation Administration ("FAA") Type Certificate for technical revisions
to its product, to obtain a FAA Production Certificate for its product, to repay
borrowings under a bridge loan, to expand the Company's sales and marketing
efforts, to establish a new manufacturing facility, and to acquire production
materials and additional tooling and equipment.

2.  NET LOSS PER COMMON SHARE

The Company's net loss per common share was computed based on the weighted
average number of shares of common stock outstanding during the nine-month
periods ended September 30, 1999 and 1998 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. There is no difference
between the loss per common share amounts computed for basic and dilutive
purposes because the impact of options and warrants outstanding are anti-
dilutive.

3.  SALE AND LEASEBACK TRANSACTION

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

                                       7
<PAGE>

As part of this transaction, the Company and AP-Long Beach Airport LLC have
entered into an agreement pursuant to which AP-Long Beach Airport LLC has:
subleased the land to the Company subject to the terms at the original land
lease agreement which was assigned to AP Long Beach Airport LLC and leased the
manufacturing hangar facility and finished office space to the Company for an
original term of 18 years. The monthly rent under this facility lease is
approximately $106,000. The Company has an option to extend the original term
for an additional ten years. The monthly rent payable during this additional ten
year term would be the market rental value, as agreed by the parties or as
determined by a third party appraiser or broker. The $306,000 gain on the sale
of the facility, which was deferred, is being amortized over the 18-year lease
term.

4.  INDUSTRIAL DEVELOPMENT BONDS

On August 5, 1997, the Company entered into a loan agreement in connection with
industrial development bonds (IDB) issued by the California Economic Development
Financing Authority. The Company had established in the trustee's favor a bank
letter of credit for the principle amount of  $8,500,000, plus 45 days accrued
interest on the bonds, which was secured by $8,500,000 of Company restricted
cash. The Company had used the proceeds from the IDBs to finance the
construction and installation of the 200,000 square foot manufacturing facility
and related manufacturing equipment.

On June 1, 1999, the Company retired all the industrial development bonds using
the restricted cash previously held as security for the IDB.

5.  CONVERSION OF SHARES

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

6.  ACCOUNTING PRONOUNCEMENTS

The FASB issued SFAS No. 133, "Accounting for Derivative Instruments and Hedging
Activities," which is effective for fiscal years beginning after June 15, 2000,
as amended. SFAS No. 133 establishes accounting and reporting standards for
derivative instruments. The statement requires that every derivative instruments
be recorded in the balance sheet as either an asset or liability measured at its
fair value, and that changes in the derivative's fair value be recognized
currently in earnings unless specific hedge accounting criteria are met.
Management believes that the adoption of SFAS No. 133 will not have a material
effect on the Company's financial statements.

ITEM 2.  PLAN OF OPERATIONS

  Certain statements contained in this report, including statements concerning
the Company's future cash and financing requirements, the Company's ability to
obtain market acceptance of its aircraft, the Company's ability to obtain
regulatory approval for its aircraft, and the competitive market for sales of
small business aircraft and other statements contained herein regarding matters
that are not historical facts, are forward looking statements; actual results
may differ materially from those set forth in the forward  looking statements,
which statements involve risks and uncertainties, including without limitation
to those risks and uncertainties set forth in the Company's Registration
Statement on Form SB-2 (No. 333-12273) under the heading "Risk Factors."

  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 March 1990, the Company made
application to the FAA for a Type Certificate for the JETCRUZER 450, which
Certificate was ultimately granted in June 1994. The Company has not generated
any operating revenues to date and has incurred losses from such activities. The
Company believes it will continue to experience losses until such time as it
commences the sale of aircraft on a commercial scale.

  Prior to commencing commercial sales of the JETCRUZER 500, the Company will
need to, among other things, complete the development of the aircraft, obtain
the requisite regulatory approvals, hire additional engineering and
manufacturing personnel and expand its sales and marketing efforts.  The Company
estimates that the cost to complete development of the JETCRUZER 500 and obtain
an amendment of its FAA Type Certificate will be approximately $5,000,000.  This
amount includes the cost of equipment and tooling, static and flight testing of
the aircraft and the employment of the necessary personnel to build and test the
aircraft.

  The Company expects to receive progress payments during the construction of
aircraft and final payments upon the delivery of aircraft.  However, the Company
believes it will continue to experience losses until such time as it commences
the sale of aircraft on a commercial scale.

  During the balance of 1999, the Company intends to focus its efforts in the
following areas:

 .  Completion of the development of the JETCRUZER 500, including, among other
   things, pressurization, environmental systems, de-icing capability and
   autopilot certification.

 .  Obtaining 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.

 .  Establishing a production line and acquiring production inventory and
   additional items of equipment, tooling and computer hardware and software
   systems.

 .  Obtaining a production certificate from the FAA and commencing commercial
   production of the JETCRUZER 500.

 .  Increasing its engineering, manufacturing and administrative staff in
   anticipation of increased development and production activities.

  The Company believes that the remaining net proceeds from its December 1996
initial public offering ("IPO"), and the proceeds of the sale and lease back of
the New Facility, will be sufficient to finance its plan of operations for at
least the next nine months, based upon the current status of its business
operations, its current plans and current economic and industry conditions.  If
the Company's estimates prove to be incorrect, then during such period the
Company may have to seek additional sources of financing, reduce operating costs
and/or curtail growth plans.

LIQUIDITY AND CAPITAL RESOURCES

  At September 30, 1999, the Company had working capital of $3,944,000 and
stockholders' equity of $3,858,000. Since its inception in January 1990, the
Company has experienced continuing negative cash flow from operations, which,
prior to the December 1996 IPO, resulted in the Company's inability to pay
certain existing liabilities in a timely manner. The Company has financed its
operations through private funding of equity and debt and its December 1996 IPO.

  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.

  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.

  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 were
automatically converted to Class A Warrants upon completion of the IPO). 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 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 used a portion of the
net proceeds of the IPO to repay the Bridge Notes. Additionally, in 1996, the
Company recognized an extraordinary loss of approximately $942,000, representing
the combined unamortized debt discount and issuance costs arising from the
Bridge Financing, in the quarter in which the Bridge Notes were repaid.

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

  The Company expects that the remaining net proceeds of the December 1996 IPO,
and the proceeds of the sale and lease back of the New Facility will enable it
to meet its liquidity and capital requirements for at least the next nine
months, by which time the Company expects to have commenced commercial
production, started collection of customer progress payments and increased sales
of the JETCRUZER 500. Such proceeds will be used and have been used primarily
for amendment of the Type Certificate, the purchase of equipment and tooling and
sales and marketing. The Company's capital requirements are subject to numerous
contingencies associated with development stage companies. Specifically 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 amended certification and may
therefore have a material and adverse effect on the Company's operations.
Further, if the Company has not completed the development of the JETCRUZER 500,
received the required regulatory approvals and successfully commenced commercial
production of its aircraft by the third quarter of 2000, 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 was not
obtained, the Company would be materially and adversely affected and might have
to substantially reduce operations.

  The Company's 200,000 square foot manufacturing and headquarters facility (the
"New Facility") was sold for $9,800,000 on May 19, 1999 and subsequently leased
back for a term of 18 years, with an option to extend for a additional 10 years.
The primary financing for the construction of the facility was the Company's
obligation under a loan agreement related to proceeds received from $8,500,000
in the issuance of Industrial Development Bonds (IDB) by the California Economic
Development Financing Authority (the "Authority"). The Company was required to
provide cash collateral to Sumitomo Bank, Limited (the "Bank") in the amount of
$8,500,000 for a stand-by letter of credit in favor of the holders of the IDBs.

  On June 1, 1999, the Company retired all the industrial development bonds,
using the restricted cash previously held as security for the IDB.

  As part of the sale-leaseback transaction described in Note 3 of the Financial
Statements, the Company assigned to AP-Long Beach Airport LLC its lease for
approximately 10 acres of land located on the Long Beach Airport in Long Beach,
California. This lease commenced on January 14, 1998, was for a term of 30
years, with an option to renew for an additional 10 years, and also contained
options to lease other airport properties. Also as part of the sale-leaseback
transaction, the Company entered into a sublease with AP-Long Beach Airport LLC
on the same terms as the assigned lease. The monthly rent under the sublease is
currently $7,400. The sublease contains incremental increases that escalate the
monthly rent to approximately $15,600 after 5 years.

  The Company has purchased a new integrated manufacturing, production and cost
control computer system, to support future Company growth and production
requirements. The system has been certified as Year 2000 compliant. Management
expects to have the new system installed and running during second half of 2000
and estimates the associated costs to be immaterial to the Company's operations.

  The Company had no material capital commitments at September 30, 1999, other
than discussed in this report. The Company intends to hire a number of
additional employees, which will require substantial capital resources. The
Company anticipates that it will hire up to 200 employees over the next twelve
months, including engineers and manufacturing technicians necessary to produce
its aircraft.

YEAR 2000 COMPLIANCE

  Management believes it has an effective program in place to resolve the Year
2000 issue in a timely manner. As noted below, the Company has not yet completed
all necessary phases of the Year 2000 program.

  In May 1998, the Company signed a contract with Baan Business Systems of
California for license and implementation of the Baan ERP system. The Company
has received assurances from Baan that the hardware and software is Year 2000
compliant. Training and implementation began in the 3rd quarter of 1998 and is
scheduled to be completed in the 2nd half of 2000. Although the Company does not
perceive any problems with its new computer system, the failure of the new
hardware and software package to be Year 2000 compliant might result in
significant unexpected costs, which would have a material adverse effect on the
Company's results of operations. The Company has completed its assessment of its
major vendors and has concluded there is no significant Year 2000 problem with
such vendors or their products.

  The Company is currently assessing various other vendors, which it plans to
utilize when production of the JETCRUZER 500 begins. The process of evaluation
includes both the significance of the vendors to the Company's operation and
their exposure to the Year 2000 problem. The Company does not anticipate any
material costs in completing its Year 2000 program.

  The Company currently has no contingency plans in place in the event it does
not complete all phases of the Year 2000 program. The Company plan is currently
to evaluate the status of completion and will determine whether such a plan is
necessary.

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