              NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS



1.   The accompanying statements are unaudited and have been prepared by ECC
     pursuant to the rules and regulations of the Securities and Exchange
     Commission. The June 30, 1997 consolidated balance sheet was derived from
     audited financial statements but does not include all disclosures required
     by generally accepted accounting principles. In the opinion of management
     the accompanying unaudited consolidated financial statements contain all
     adjustments, consisting of only normal recurring adjustments, necessary to
     present fairly the consolidated financial position, results of operations
     and cash flows for the interim period presented. These unaudited
     consolidated financial statements should be read in conjunction with the
     consolidated financial statements and footnotes thereto in the Company's
     1997 Annual Report to Shareholders.


2.   Loss per common share is computed by dividing net loss by the weighted
     average number of common shares outstanding during the period without
     giving effect to the exercise of outstanding stock options assumed
     converted to common stock due to these incremental shares being
     anti-dilutive.

     Earnings per common share is computed by dividing net income by the
     weighted average number of common shares outstanding during the period
     after giving effect to the exercise of outstanding stock options assumed
     converted to common stock.

3.   The Company did not comply with the minimum fixed charge coverage ratio at
     September 30, 1997 under its Term Loan and Revolving Credit Agreement and,
     accordingly, has received an irrevocable waiver with respect to such
     covenant from its bank lender. The Company made the two final required
     payments on its term loan totaling $2,250,000 during the first quarter of
     fiscal year 1998.

     Due to the pending re-negotiation of the Revolving Credit Agreement, the
     Company's bank lenders extended the expiration date to October 1, 1998. As
     such, the amount originally due on September 30, 1998 continues to be
     classified as long-term debt on the Consolidated Balance Sheets at
     September 30, 1997.

4.   In February 1997, the Financial Accounting Standards Board ("FASB") issued
     Statement of Financial Accounting Standards No. 128, "Earnings Per Share"
     ("SFAS 128"). SFAS 128 specifies new standards designed to improve the
     earnings per share ("EPS") information provided in financial statements by
     simplifying the existing computational guidelines, revising the disclosure
     requirements, and increasing the comparability of EPS data on an
     international basis. Changes made to simplify the EPS computation include:
     eliminating the presentation of primary EPS and replacing it with basic
     EPS, with the principal difference being that common stock equivalents are
     not considered in computing basic EPS. The statement is effective for
     periods ending after December 15, 1997, with prior periods restated to
     comply with the new standard at that time. If the new standard had been
     effective for the periods ended September 30, 1997 and 1996, there would
     have been no significant change in (loss)/earnings per share as presented
     in the accompanying Consolidated Statements of Operations.

5.   On September 25, 1997, the Company announced a tentative agreement with
     Maytag Corporation for the purchase for cash by Maytag of the technology,
     fixed assets, inventory and trade receivables of the Company's vending
     operation. The agreement is subject to final negotiations and a definitive
     agreement between the parties. The proposed sale is currently expected to
     be completed during the second quarter of fiscal year 1998. It is currently
     anticipated that proceeds from the sale of the vending operation will be
     used to reduce the Company's debt.

     Operating results have been segregated in the accompanying consolidated
     statements of operations. Net losses of the discontinued operation were
     $721,000 for the three-month period ended September 30, 1997. This compares
     to a $526,000 net loss for the three-month period ended September 30, 1996.
     The net loss for the three-month period ended September 30, 1997 was
     included as a component of discontinued operations in the Company's June
     30, 1997 consolidated financial statements. Discontinued operations at June
     30, 1997 included and continue to represent managements' best estimates of
     the amounts expected to be realized on the proposed sale of the vending
     operation, the costs directly associated with the disposal of the
     operation, as well as the operating losses expected to be incurred during 
     the phase-out period. There can be no assurance that the actual amounts 
     will not exceed management's estimates or that such actual amounts will not
     have a material adverse effect on the Company's financial condition and 
     results of operations.

                    ECC INTERNATIONAL CORP. AND SUBSIDIARIES
                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS


     OVERVIEW

     This Quarterly Report on Form 10-Q contains forward-looking statements
     within the meaning of Section 21E of the Securities Exchange Act of 1934,
     as amended. For this purpose, any statements contained herein that are not
     statements of historical fact may be deemed to be forward-looking
     statements. Without limiting the foregoing, the words "believes,"
     "anticipates," "plans," "expects," and similar expressions are intended to
     identify forward-looking statements. There are a number of factors that
     could cause the Company's actual results to differ materially from those
     indicated by such forward-looking statements. These factors include,
     without limitation, those set forth below under the caption "Certain
     Factors that May Affect Future Operating Results."

a)   MATERIAL CHANGES IN FINANCIAL CONDITION.

     During the three-month period ended September 30, 1997, the Company's
     principal sources of cash were billings and receipts on costs and estimated
     earnings in excess of billings on completed contracts and advances on
     contracts in the UK subsidiary. The principal uses of these and existing
     funds were to make the final payments on the term loan, to finance the
     increase in inventories and to fund improvements to the Orlando facility.

     Accounts receivable increased primarily due to billings in late September
     on two large F18 contracts. Payment on these billings was received in the
     second quarter of fiscal year 1998.

     Costs and estimated earnings in excess of billings on completed contracts
     decreased due to the completion or near completion of several contracts in
     the domestic training division.

     Work in process inventory increased primarily due to unabsorbed overhead.
     Overhead is absorbed on an annualized projected rate. Management expects
     that volume during the remaining fiscal 1998 quarters will support the
     currently budgeted overhead rate.

     Finished goods inventory decreased as a result of the sale of vending units
     inventoried at June 30, 1997.

     Prepaid expenses and other increased primarily due to the federal tax
     benefit recorded during the first quarter of fiscal year 1998 for federal
     net operating losses realized in that period.

     Accrued expenses increased as a result of accruals for payroll related
     expenditures, including profit sharing contributions and employee stock
     purchases. In addition, accruals for marketing representative commissions
     and fees increased during the first quarter of fiscal year 1998.

     The increase in capital in excess of par was primarily the result of
     employee stock bonuses issued during the first quarter of fiscal year 1998.


<PAGE>   9

     The Company did not comply with the minimum fixed coverage ratio at
     September 30, 1997 under its Term Loan and Revolving Credit Agreement.
     Accordingly, the Company has received irrevocable waivers from its bank
     lenders with respect to this covenant. The Company made the two final
     required payments on its term loan totaling $2,250,000 during the first
     quarter of fiscal year 1998.

     Due to the pending re-negotiation of the Revolving Credit Agreement, the
     Company's bank lenders extended the expiration date to October 1, 1998. As
     such, the amount originally due on September 30, 1998 continues to be
     classified as long-term debt on the Consolidated Balance Sheets at
     September 30, 1997.

     During the remainder of fiscal year 1998, the Company anticipates spending
     approximately $2.1 million for new machinery and equipment and to continue
     to refurbish the Orlando facility.

     Other than as stated above, the Company currently has no other material
     commitments for capital expenditures. Management believes that with funds
     available under its loan facility and its projected cash flows the Company
     will have sufficient resources to meet current and future operating
     commitments.

b)   MATERIAL CHANGES IN RESULTS OF OPERATIONS.

     Continuing Operations

     Net sales decreased for the three-month period ended September 30, 1997 as
     compared to the same period ended September 30, 1996. The decrease in net
     sales is primarily the result of several domestic training division
     contracts with reduced activity as they are complete or near completion.
     Sales volume in the UK subsidiary also decreased substantially over the
     corresponding period in the prior fiscal year as the activity on its two
     major contracts has declined as they are expected to be completed during
     fiscal year 1998. In addition, there have been no significant contract
     awards in the UK subsidiary over the past fiscal year.

     Overall gross margin as a percentage of sales increased marginally for the
     three-month period ended September 30, 1997 versus the same period ended
     September 30, 1996.

     The domestic training division was awarded a large Javelin multi-year
     contract as well as several additions to other ongoing contracts late in
     the first quarter of fiscal year 1998. However, significant work did not
     commence on these contracts until the second quarter of fiscal year 1998
     and therefore no revenues were realized which could have partially or fully
     offset the decline in sales during the first quarter of fiscal year 1998.
     While cost reduction initiatives continue, overhead and S,G&A levels have
     not decreased proportionate to the decrease in sales volume. Management
     anticipates that the award of the large Javelin multi-year contract,
     additions to several ongoing contracts, combined with further cost
     reduction initiatives, will result in improved results during fiscal year
     1998.

     Systems development expense increased for the three-month period ended
     September 30, 1997 versus the corresponding period in the previous fiscal
     year. The increase is primarily the result of efforts in the domestic
     training division to develop and/or enhance technologies and processes in
     order to remain competitive in the industry.

     Interest expense decreased for the three-month period ended September 30,
     1997 versus the corresponding period in the previous fiscal year. The
     decrease is a result of the final payments totaling $2,250,000 made on the
     Company's term loan during the first quarter of fiscal year 1998.

     Discontinued Operations

     On September 25,1997, the Company announced a tentative agreement with
     Maytag Corporation for the purchase for cash by Maytag of the technology,
     fixed assets, inventory and trade receivables of the Company's vending
     operation. The agreement is subject to final negotiations and a definitive
     agreement between the parties. The proposed sale is currently expected to
     be completed during the second quarter of fiscal year 1998. It is currently
     anticipated that proceeds from the sale of the vending operation will be
     used to reduce the Company's debt.

     Operating results have been segregated in the accompanying consolidated
     statements of operations. Net losses for the discontinued operation were
     $721,000 for the three-month period ended September 30, 1997. This compares
     to a $526,000 net loss for the three-month period ended September 30, 1996.
     The net loss for the three-month period ended September 30, 1997 was
     included as a component of discontinued operations in the Company's June
     30, 1997 consolidated financial statements. Discontinued operations at June
     30, 1997 included and continue to represent managements' best estimates of
     the amounts expected to be realized on the proposed sale of the vending
     operation, the costs directly associated with the disposal of the
     operation, as well as the operating losses expected to be incurred during
     the phase-out period. There can be no assurance that the actual amounts
     will not exceed management's estimates or that such actual amounts will not
     have a material adverse effect on the Company's financial condition and
     results of operations.

c)   CERTAIN FACTORS THAT MAY AFFECT FUTURE OPERATING RESULTS.

     The following important factors, among others, could cause actual results
     to differ materially from those indicated by forward-looking statements
     made in this Quarterly Report on Form 10-Q and presented elsewhere by
     management from time to time. All forward-looking statements included in
     this document are based on information available to the Company on the date
     hereof, and the Company assumes no obligation to update any such
     forward-looking statements.

     A number of uncertainties exist that could affect the Company's future
     operating results, including, without limitation, general economic
     conditions, changes in government spending, cancellation of weapons
     programs, delays in contract awards, delays in the acceptance process of
     contract deliverables, the Company's continued ability to develop and
     introduce products, the introduction of new products by competitors,
     pricing practices of competitors, the cost and availability of parts and
     the Company's ability to control costs.

     To date, a substantial portion of the Company's revenues have been
     attributable to long-term contracts with various government agencies. As a
     result, any factor adversely affecting procurement of long-term government
     contracts could have a material adverse effect on the Company's financial
     condition and results of operations.

     On September 25, 1997, the Company announced a tentative agreement with
     Maytag Corporation whereby Maytag would acquire the technology, fixed
     assets, inventory and trade receivables of ECC Vending Corp. The agreement
     is subject to final negotiations and a definitive agreement between the
     parties.



<PAGE>   11



     Because of these and other factors, past financial performance should not
     be considered an indication of future performance. The Company's future
     quarterly operating results may vary significantly, depending on factors
     such as the timing of contract awards. Investors should not use historical
     trends to anticipate future results and should be aware that the trading
     price of the Company's Common Stock may be subject to wide fluctuations in
     response to quarterly variations in operating results and other factors,
     including those discussed above.
