              NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
                                   (UNAUDITED)

                                December 31, 1999

NOTE 1 -- BASIS FOR PRESENTATION

The accompanying unaudited consolidated 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 information and footnotes
required by generally accepted accounting principles for complete financial
statements.

In the opinion of management, all adjustments (consisting of normal recurring
accruals) considered necessary for a fair presentation have been included.
Operating results for the quarter are not necessarily indicative of the results
that may be expected for the year ended September 30, 2000. For further
information, refer to the consolidated financial statements and footnotes
thereto included in the Company's annual report on Form 10-K for the year ended
September 30, 1999.

The preparation of the 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.

Certain prior period amounts have been reclassified to conform to current period
classifications.

NOTE 2 -- PER SHARE AMOUNTS

Per share amounts are based upon the weighted average number of shares of common
stock outstanding.

                                CUBIC CORPORATION
           ITEM 2 - MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                       CONDITION AND RESULTS OF OPERATIONS

                                December 31, 1999

RESULTS OF OPERATIONS

Revenues for the first quarter of fiscal 2000 were 17% higher than the first
quarter of fiscal 1999, as the result of higher sales in both the defense and
transportation segments and increased investment income, due to increased cash
available for investment. The increase in sales came primarily from ground
combat training systems in the defense segment and from the PRESTIGE contract in
the transportation segment. The increase in cash available for investment was
the result of nearly $50 million in positive cash flow from operating activities
in fiscal 1999 and another $17.5 million provided by operating activities in the
quarter ended December 31, 1999.

Operating profits in the defense segment increased as the result of the increase
in sales volume and as the result of somewhat higher margins from the JSTARS
product line, which continues to perform well. Operating profits in the
transportation segment also increased due to the increased sales volume,
however, the operating margins contributed by the PRESTIGE contract continue to
be modest as the program is still in its early stages of completion. In
addition, an improvement in operating profits resulted from the Company having
discontinued the video email product line in the fourth quarter of fiscal 1999.
The increase in other profits reflects the higher investment income, as
described above.

For the three-month period, selling, general and administrative expenses
increased modestly, in support of the higher sales volume, but decreased as a
percentage of sales. The increased spending resulted primarily from selling
costs in both the defense and transportation systems segments as proposal
activity related to new business prospects increased.


LIQUIDITY AND CAPITAL RESOURCES

The $17.5 million in cash provided by operating activities resulted primarily
from accelerated collections of accounts receivable in both the defense and
transportation segments. This included the collection of a significant portion
of the amounts related to contract claims in the transportation segment that had
been outstanding for more than a year. The amounts remaining in accounts
receivable subject to contract claims were not significant at December 31, 1999.

The Company's financial condition remains strong with working capital of $164
million and a current ratio of 3.1 to 1 at December 31, 1999. The Company
expects that cash on hand will be adequate to meet its short-term working
capital requirements for the foreseeable future. The backlog of orders at
December 31, 1999 was $843 million compared to $907 million at September 30,

YEAR 2000 ISSUE

The Company has completed its Year 2000 (Y2K) Project as scheduled and the
possibility of significant interruptions of normal operations has been reduced.
As of January 27, 2000, the Company's products, computing, and communications
systems have operated without any significant problems and the Company believes
that its systems have successfully made the Y2K transition. The Company is also
not aware of any of its major customers or third-party suppliers having
experienced significant Y2K related problems. However, there can be no assurance
that the Company has discovered all possible failure points. Factors
contributing to this uncertainty include possible failure to identify all
systems, unprepared third parties whose systems and operations impact the
Company, and other similar uncertainties. Contingency plans are complete and
will be implemented if required.

Through December 31, 1999, the Company expensed approximately $1,000,000 of
incremental Y2K remedial costs, consisting primarily of internal labor. The
Company currently does not expect to incur any significant additional Y2K
related costs, and any such costs will continue to be expensed as incurred.
