                     NOTES TO CONDENSED FINANCIAL STATEMENTS
                           (Unaudited, 000's omitted)
                                 June 30, 2002

NOTE A - BASIS OF PRESENTATION

         The accompanying unaudited condensed financial statements have been
         prepared in accordance with generally accepted accounting principles
         for interim financial information and with the instructions to Form
         10-Q and Article 10 of Regulation S-X. Accordingly, they do not
         include all of the information and footnotes required by generally
         accepted accounting principles for complete financial statements. In
         the opinion of management, all adjustments (consisting solely of normal
         recurring accruals) considered necessary for a fair presentation have
         been included. Operating results for the six-month period ending June
         30, 2002 are not necessarily indicative of the results that may be
         expected for the year ended December 31, 2002. For further information,
         refer to the financial statements and footnotes thereto included in the
         Company's annual report on Form 10-K for the year ended December 31,
         2001.

NOTE B - INCOME TAXES

         Income taxes are provided on an interim basis based upon management's
         estimate of the annual effective tax rate. The income tax rate in 2001
         is not comparable to the current year rate due to the termination of
         the intercompany tax sharing agreement in September 2001 when Minnesota
         ASE acquired 51% of the Company's outstanding stock from Celsius Inc.

Item 2.  Management's Discussion and Analysis of Financial Condition
         And Results of Operations

In addition to historical information, this Quarterly Report contains
forward-looking statements. The forward-looking statements are subject to
certain risks and uncertainties that could cause actual results to differ
materially from those reflected in such forward-looking statements. Factors that
might cause a difference include, but are not limited to, general economic
conditions, the condition of the aerospace industry, signing of future
contracts, competitive factors and other risks detailed from time to time in the
Company's reports to the SEC, including the report on Form 10-K for the year end
December 31, 2001. Actual results may vary materially from those anticipated.

Results of Operations

Second quarter 2002 (All dollar amounts are in thousands.)

Worldwide revenue for second quarter 2002 totaled $10,973 which was a 80%
increase from $6,093 in second quarter of last year. Net income for second
quarter was $525 as compared to the second quarter loss of $96 last year.

Backlog of orders as of June 30, 2002 was $26,201 as compared with $29,483 and
$27,303 as of December 31, 2001 and June 30, 2001, respectively. This 4%
decrease from second quarter 2001 is mostly the result of the conversion of
backlog to revenue on the large Singapore wind tunnel project. The total orders
received during the second quarter were $6,300.

The strong revenue increase experienced by the Company was mostly attributable
to the increase in orders in process, resumption of normal activities on the
Singapore wind tunnel project since receipt of the export license in early
September 2001 and success in new initiatives in new markets. The improvement
in net income in the second quarter was mostly due to increased revenues. Also,
interest expense was reduced as a result of lower interest rates and lower debt
levels.

Cost of earned revenue for second quarter of 2002, which includes manufacturing
and engineering costs, was 78% of revenue as compared to 73% during the same
period of last year. This increase is mostly the result of work shifting to
slightly lower margin projects in the wind tunnel portion of the business during
the second quarter 2002.

The Company recognizes revenue and profit as work on long-term contracts
progresses using the percentage-of-completion method of accounting, which relies
on estimates of total expected contract revenues and costs. The Company follows
this method since reasonably dependable estimates of the revenue and costs
applicable to various stages of a contract can be made. Because the financial
reporting of these contracts depends on estimates, which are assessed
continually during the term of the contract, recognized revenues and profit are
subject to revisions as the contract progresses to completion. Revisions in
profit estimates are reflected in the period in which the facts that give rise
to the revision become known. Accordingly, favorable changes in estimates result
in additional profit recognition, and unfavorable changes in estimates result in
the reversal of previously recognized revenue and profits. When estimates
indicate a loss under a contract, cost of revenue is charged with a provision
for such loss. As work progresses under a loss contract, revenue continues to be
recognized, and a portion of the contract costs incurred in each period is
charged to the contract loss reserve.

Selling, general and administrative expenses of $1,474 were 13% of revenues
during second quarter 2002 as compared to $1,399 and 23% during the same period
of last year. The increase of $75 is mostly related to higher corporate legal
fees.

Research and development expenses were $105 during second quarter of 2002 as
compared to $137 in the same period in 2001. This decrease of $32 or 23% is
mostly related to the focus of certain resources in second quarter 2002 on
project work rather than on R&D activities. During the remainder of 2002,
additional R & D will be incurred for continued enhancements to the ASE2000,
aero-acoustic analysis and new product initiatives.

Interest expense of $86 was incurred during the second quarter 2002 as compared
to $189 from the same period in the prior year. The average rate of interest on
short-term borrowings was lower partially as a result of the interest rate
reductions experienced during latter portion of 2001 and partially due to the
new bank agreements. Also, the average amount of borrowings outstanding has
decreased in the second quarter 2002 as compared to the second quarter of last
year mostly due to the Company's ability to resume normal invoicing activities
on the Singapore wind tunnel project after the receipt of the export license.

Income tax expense was $270 for the second quarter 2002 as compared to $0 for
the second quarter of 2001. Income taxes are provided on an interim basis based
upon management's estimate of the annual effective tax rate. The income tax rate
in 2001 is not comparable to the current year rate due to the termination of the
intercompany tax sharing agreement in September 2001. Through September 25,
2001, Aero Systems was included in the consolidated federal income tax return of
Celsius Inc., which owned 80% of the Company's outstanding stock. The Company's
income tax provision was calculated and presented on a separate return basis.
As a result of the acquisition of 51% of Aero Systems's stock by Minnesota ASE,
LLC, Celsius Inc. now owns less than 80% of Aero Systems and, accordingly, is no
longer able to include Aero Systems in its consolidated federal income tax
return.

Financial Condition

Accounts receivable at the end of second quarter 2002 was $6,013 as compared
with the year end balance of $4,730. This increase of $1,283 was due mainly to
the timing of project billing milestones resulting in several large invoices
outstanding at the end of the second quarter of 2002.

Costs and estimated earnings in excess of billings on uncompleted contracts at
the end of second quarter 2002 was $5,664, which is an increase of $787 or 16%
as compared with the year-end 2001 balance. The Company recognizes profit on
long-term projects on the percentage of completion basis, which permits earned
revenue to be recognized prior to the time that progress payments are billed.
When this occurs, amounts are added to this asset account for the recognition of
earned revenue prior to the billing of progress payments. The increase since
year-end is due to the timing of billing milestones related to the contracts.
Billings are a function of contract terms and do not necessarily relate to the
percentage of completion of a project.

Notes payable balances totaled $300 as compared to the year-end 2001 balance of
$2,000, which is a decrease of $1,700 or 85%. This decrease is primarily the
result of the timing of project expenditures as compared to invoicing milestones
resulting in the repayment of the bank line of credit down to $0 and $1,735 of
cash on hand at the end of the second quarter.

Accounts payable and accrued expenses totaling $8,143 at the end of second
quarter 2002 increased $2,605 or 47% as compared to the year-end 2001 balance.
This was primarily due to an increase in accrued job costs relating to ongoing
projects.

Billings in excess of costs and estimated earnings on uncompleted contracts at
the end of second quarter 2002 increased $1,464 to $3,155 compared to the
year-end 2001 balance of $1,691. The increase since year-end is due to the
timing of billing milestones related to contracts. Billings are a function of
contract terms and do not necessarily relate to the percentage of completion of
a project.

Liquidity and Capital Resources

The Company has consistently relied upon bank credit lines during recent years
as a source of its working capital resources and liquidity. During the third
quarter 2001, Celsius Inc. sold 51% of the total outstanding shares of common
stock of ASE to Minnesota ASE, LLC. Related to this transaction, the Company has
secured new bank financing agreements for operating funds and future letter of
credit needs. These new agreements are asset based collateral agreements, with
the funds available under these agreements determined by the available securable
assets at any point in time, up to a maximum of $6,000 of operating funds, and
$3,000 of letter of credit funds. Also related to the transaction, Celsius Inc.
has agreed to continue to hold certain existing bank guarantees until maturity
that were previously provided to a few of the Company's customers, and Celsius
Inc. has provided a three year $1,500 loan to the Company at 8% per year, which
is subordinated debt under the new bank agreement. The Company has provided an
indemnification agreement to Celsius Inc. to secure Celsius Inc.'s interest in
the above items. The average funds available and amounts outstanding on the
operating line and letter of credit during the second quarter 2002 were $281
outstanding on $2,897 available and $2,480 outstanding on $3,000 available,
respectively.

At the end of the second quarter 2002, the Company had notes payable balances of
$300 current and $1,500 long term. The current notes payable balance of $300
consisted of $300 of interim loans provided by Minnesota ASE, LLC. The $300 note
to Minnesota ASE, LLC is at 8% per year and does not have a stated maturity
date. The Company believes that these bank lines of credit, along with cash
flows from continuing operations, are adequate to support the Company's cash
needs for the immediate future.

Capital expenditures during the second quarter 2002 were $146 as compared to
$152 for the same period of last year. Additional capital expenditures will be
used to acquire additional equipment for research and development projects,
facility improvements and desktop upgrades. We expect the total capital
expenditures for the year ending December 31, 2002 to approximate the year ended
December 31, 2001.

Market Risk

The Company operates on a global basis and, during an average year, generates
approximately 50% of its revenues from international customers. This trend has
continued for the last five years as foreign airlines and government agencies
purchase products that ASE designs and produces. Most of the Company's contracts
are denominated in U.S. dollars. However, a few of them are denominated in the
customer's local currency. Therefore, the Company has entered into foreign
exchange forward contracts having maturities within the next eighteen months.
The face amounts represent U.S. dollar equivalents of a non-U.S. dollar
denominated forward contract. The amounts at risk are not material, and the
Company has the financial ability to generate cash flows to offset the expected
gains or losses when the contracts mature. The Company is also subject to
interest rate risk. The Company has not hedged its exposure to interest rate
fluctuations; however, a 10% increase or decrease in interest rates would not
have a material effect on the Company's results of operations, fair values, or
cash flows.

Forward-Looking Information

Highly competitive market conditions have minimized the margins on new
contracts. Productivity improvements and cost reduction programs are continually
being initiated to increase margins.

Looking ahead throughout the remainder of 2002, the amount of business in
backlog and the number of proposals outstanding should continue to provide a
solid base for the remainder of the year.
