QUIXOTE CORPORATION AND SUBSIDIARIES

Notes to Consolidated Financial Statements

(Unaudited)

1.     The accompanying unaudited consolidated financial statements present information in accordance with generally accepted accounting principles for interim financial
information and applicable rules of Regulation S-X. Accordingly, they do not include all information or footnotes required by generally accepted accounting principles for complete financial
statements. The June 30, 2002 consolidated balance sheet as presented was derived from audited financial statements. The interim financial statements and notes should be read in conjunction
with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended June 30, 2002. Management believes the financial
statements include all normal recurring adjustments necessary for a fair presentation of the results for the interim periods presented.

2.     The
provision for income taxes is based upon the estimated effective income tax rate for the year.

3.     Operating
results for the first nine months of fiscal 2003 are not necessarily indicative of the performance for the entire year. Historically, the Company's business is
seasonal with a higher level of sales in the Company's fourth fiscal quarter.

4.     The
computation of basic and diluted earnings per share is as follows:

|                                                   |         | Nine Months Ended March 31, |           | Three Months Ended March 31,

PART IFINANCIAL INFORMATION

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

CURRENT YEAR-TO-DATE VERSUS PRIOR YEAR-TO-DATE

The Company's sales for the first nine months of fiscal 2003 increased 21% to $75,472,000 compared to $62,279,000 for the first nine months last year. Sales for
the first nine months of fiscal 2002 were unusually low as the Company believes it was affected by generally weak economic conditions. Sales for the Protect and Direct segment increased 16% to
$53,822,000 from $46,370,000 primarily due to higher sales of the QuadGuard® family of crash cushions, truck-mounted attenuators and parts, which were partially offset by lower sales of
sand-filled barrels and the FreezeFree anti-icing system. Sales for the Inform segment increased 36% to $21,650,000 in the first nine months of fiscal 2003 from $15,909,000 for the same
period last year. The increase was primarily due to higher sales of advanced sensing systems and variable message signs, which were partially offset by lower sales of highway advisory radios. The
growth in sales of the sensing systems and variable message signs was due to shipments of two large contracts, including shipments of $2,800,000 in Ohio to supply weather and traffic sensing systems
and $550,000 in variable message signs and arrowboards in California. The increase was also due, to a lesser extent, to the acquisition of Surface Systems, Inc. (SSI) in August 2001,
which added $914,000 in sales for the first nine months not comparable to the prior year. Organic sales for this segment increased 30% for the first nine months of fiscal 2003. The Company's
international sales increased to $10,164,000 for the first nine months of fiscal 2003 from $6,229,000 last year primarily due to increased sales in Australia, Asia and Europe. A large portion of the
increase in international sales is due to an increase of $1,290,000 in sales of the Triton Barrier® product in Australia related to new legislation passed in Australia requiring positive
protection for all highway work zones.

The
gross profit margin for the first nine months of fiscal 2003 increased to 40.4% compared to 35.7% for the same period last year principally due to volume efficiencies associated with
the higher level of
sales for both segments. The increase in the gross profit margin for the Protect and Direct segment was partially offset by an unfavorable change in product mix with increased sales of lower margin
truck-mounted attenuators. The increase in the gross profit margin for the Inform segment was partially offset by an unfavorable change in product mix with increased sales of lower margin large
contract sales. The increase in the gross profit margin for the Inform segment was also offset by the lower gross margins generated at SSI as the first nine months of fiscal 2003 includes SSI's
seasonally lowest months of July and August which were not a part of fiscal 2002 results.

Research
and development expenditures remained consistent in the first nine months of fiscal 2003 at $1,543,000 compared to $1,561,000 last year. The Company continued with its work on
new products as well as upgrades and modifications to existing products including enhancements to its existing line of crash cushions.

Selling
and administrative expenses for the first nine months of fiscal 2003 increased to $20,986,000 compared to $17,087,000 for the same period last year. The increase was primarily
due to the increase in sales as well as $511,000 in additional selling and administrative expenses from SSI not comparable to the prior year. In addition, the Company incurred increased expenses
during the first nine months of fiscal 2003 compared to the same period last year relating to foreign currency losses, acquisition development efforts, certain employee related expenses and
non-recurring consulting work. As a percentage of sales, selling and administrative expenses slightly increased to 27.8% of sales for the first nine months of fiscal 2003 as compared to 27.4% for the
same period of the prior year.

Operating
profit increased to $7,979,000 for the first nine months of fiscal 2003 from $3,612,000 for the same period last year.

11

---

Interest
expense decreased to $637,000 from $949,000 in the first nine months of fiscal 2003 due to the lower level of average long-term debt outstanding and to lower interest rates.

During
the first nine months of last fiscal year, the Company recorded other income of $830,000 related to the gain on sale of certain assets of its non-highway plastic product line.

Income
taxes for the first nine months of fiscal 2003 were $2,519,000 reflecting a 34% effective income tax rate compared to a 36% effective income tax rate for the same period last
year. The decline in effective rate is due to, among other things, continued federal and state tax planning opportunities and the expected utilization of certain state tax benefits. The Company
expects its effective income tax rate to remain at 34% for fiscal 2003.

Earnings
from continuing operations for the first nine months of fiscal 2003 were $4,889,000, or $0.61 per diluted share, compared to $2,253,000, or $0.28 per diluted share, for the
first nine months last year. Net earnings for the first nine months of fiscal 2003 increased to $4,889,000, or $0.61 per diluted share, from $2,445,000, or $0.30 per diluted share, for the same period
last year. Net earnings for the first nine months of last fiscal year included a gain from discontinued operations of $192,000, net of income taxes, or $.02 per diluted share, due to the favorable
outcome of a legal settlement.

CURRENT YEAR QUARTER VERSUS PRIOR YEAR QUARTER

The Company's sales for the third quarter of fiscal 2003 increased 17% to $25,205,000 compared to $21,507,000 for the third quarter last year. Sales for the third
quarter of fiscal 2002 were unusually low as the Company believes it was affected by generally weak economic conditions. Sales for the Protect and Direct segment increased 10% to $17,836,000 from
$16,228,000 primarily due to higher sales of the QuadGuard® family of crash cushions and truck-mounted attenuators, which were partially offset by lower sales of parts. Sales for the
Inform segment increased 40% to $7,369,000 in the third quarter of fiscal 2003 from $5,279,000 for the third quarter last year. The increase was primarily due to higher sales in all of the major
product lines including weather, sensing system, advisory radio and variable message sign products. The growth in sales of the sensing system products was partially due to the remaining shipment of
$600,000 on the large contract to Ohio to supply weather and traffic sensing systems. The Company's international sales increased to $3,579,000 for the third quarter of fiscal 2003 from $2,297,000
last year due to increased sales in Australia, Asia and Canada. The increase in international sales is primarily due to an increase of $870,000 in sales of the Triton Barrier® product in
Australia related to the new legislation passed in Australia requiring positive protection for all highway work zones.

The
gross profit margin for the third quarter of fiscal 2003 increased to 39.9% compared to 35.4% for the third quarter last year principally due to volume efficiencies associated with
the higher level of sales for both segments. The increase in the gross profit margin for the Protect and Direct segment was partially offset by an unfavorable change in product mix with increased
sales of lower margin truck-mounted attenuators. The increase in the gross profit margin for the Inform segment was partially offset by an unfavorable change in product mix with increased sales of
lower margin large contract sales.

Research
and development expenditures remained consistent in the third quarter of fiscal 2003 at $635,000 compared to $667,000 last year. The Company continued with its work on new
products as well as upgrades and modifications to existing products.

Selling
and administrative expenses for the third quarter of fiscal 2003 increased to $6,877,000 compared to $5,815,000 for the third quarter last year. The increase was primarily due to
the increase in sales. In addition, the Company incurred increased expenses during the third quarter of fiscal 2003 compared to the same period last year relating to foreign currency losses and
certain employee related expenses. As a percentage of sales, selling and administrative expenses remained consistent at 27.3% of

12

---

sales
for the third quarter of fiscal 2003 as compared to 27.0% of sales for the third quarter of fiscal 2002.

Operating
profit increased to $2,537,000 for the third quarter of fiscal 2003 from $1,126,000 for the third quarter last year.

Interest
expense decreased to $187,000 from $240,000 in the third quarter of fiscal 2003 due to the lower level of average long-term debt outstanding and to lower interest rates.

Income
taxes for the third quarter of fiscal 2003 were $803,000 reflecting a 34% effective income tax rate compared to a 36% effective income tax rate for the third quarter last year.

Net
earnings for the third quarter increased to $1,558,000, or $0.20 cents per diluted share, compared to $569,000, or $.07 cents per diluted share, for the third quarter last year.

LIQUIDITY AND CAPITAL RESOURCES

The Company had cash and cash equivalents of $897,000 as of March 31, 2003 and access to additional funds of $20,500,000 under an unsecured revolving
credit agreement which currently expires on October 31, 2004. The Company believes that this credit facility is an important source of liquidity. The credit agreement provides for a $40 million
credit facility and contains both fixed and floating interest rate options, at the prime rate or lower, and contains affirmative and negative covenants including requirements that the Company maintain
certain financial ratios and be profitable each year. The agreement may be renewed one additional year on each anniversary date upon mutual consent of the Company and the banks. At any time before the
facility expires, the Company may elect to convert the loan to a four-year term with equal quarterly principal payments due throughout the term to amortize the loan in full. The Company is currently
in compliance with all covenants in this agreement.

Operating
activities were a source of cash for the Company for the first nine months of fiscal 2003 providing $9,906,000.

Investing
activities used cash of $1,957,000 during the first nine months of fiscal 2003 including $1,512,000 for capital expenditures and $445,000 for patent expenditures.

Financing
activities used cash of $8,880,000 during the first nine months of fiscal 2003. The Company paid a net $3,000,000 against its outstanding revolving credit facility. The payment
of the Company's semi-annual cash dividend used cash of $2,486,000. In addition, the Company used cash of $876,000 for the payment of notes payable due in connection with the acquisition of Roadway
Safety Service, Inc. and National Signal, Inc. The Company also paid $3,024,000 to purchase 164,000 shares of its own common stock for the treasury. Offsetting these cash
payments, the Company received cash of $506,000 from the exercise of common stock options.

For
the remainder of fiscal 2003, the Company anticipates needing less than $1,000,000 in additional cash for capital expenditures. For 2003 and into 2004, the Company may also need
additional cash as it continues to consider acquiring businesses that complement its existing operations. Also, the Company will require additional investments in working capital to maintain growth.
The Company may also need additional funds to repurchase its own common stock from time to time. These expenditures will be financed either through the Company's invested cash, cash generated from its
operations or from borrowings available either under the Company's revolving credit facility or from the renegotiation of a new credit facility. The Company believes that additional funds would be
available from its banks if needed. The Company believes these sources of cash are sufficient for all planned operating, investing and capital requirements.

CRITICAL ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) requires
management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements.
Management's estimates also affect the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Note 2 to the Company's
June 30, 2002 consolidated financial statements includes a summary of the significant accounting policies, methods and estimates used in the preparation of the Company's consolidated financial
statements. In the opinion of management, the Company does not have any individual accounting policy or use any individual estimate that is critical to the preparation of its consolidated financial
statements. In most instances, the Company must use an accounting policy or
method because it is the only policy or method permitted under U.S. GAAP. The following is a summary of the more significant accounting policies, methods and estimates used by the Company:

Revenue
Recognition: Revenues are recognized when either title and risk of loss of products has been transferred to unaffiliated customers or services have been rendered, with
appropriate provision for uncollectible accounts.

Income
Taxes: The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax
returns. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates
in effect for the year in which the differences are expected to reverse. In addition, the amount of any future tax benefits are reduced by a valuation allowance to the extent such benefits are not
expected to be fully realized.

Long-Lived
Assets: Long-lived assets include such items as goodwill, patents, product rights and equity method investments. Long-lived assets held and used by the Company are reviewed
for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. For purposes of evaluating the recoverability of long-lived assets, the
Company assesses the possibility of obsolescence, demand, new technology, competition, and other pertinent economic factors and trends that may have an impact on the value or remaining lives of these
assets. Goodwill and other indefinite-lived intangible assets are tested for impairment at least annually using the discounted cash flow method. Patents and product rights are amortized on a
straight-line basis over the life of the patent or agreement.

In
the preparation of the Company's financial statements, certain normal and recurring estimates are made including estimates in determining the allowance for doubtful accounts
receivable, inventory valuation reserves, valuation allowance on deferred tax assets and health care liabilities. These estimates are made using management's best judgement given relevant factors and
available data. These estimates may differ from actual results.

FUTURE OUTLOOK

The Company has been affected by the general slowdown in U.S. highway safety construction spending for the Company's products. The Company believes this is due
principally to revenue shortfalls and budget deficits at the state level where the majority of states are currently operating at a deficit. Federal spending on highways for the government's fiscal
year ending September 30, 2003 has been approved at approximately $32 billion consistent with federal spending last year. The current six-year federal highway bill (TEA-21) expires on
September 30, 2003. The next highway funding bill is currently under consideration by the federal government and it is uncertain as to what the future federal governmental spending levels will
be. Currently, the Company is encouraged by recent improvements in shipments, order flow and backlog. However, given the current uncertain economic

14

---

conditions
and state budget deficits, the Company remains cautious about its prospects for 2003 and into 2004.

The
Company experiences fluctuation in its gross profit margin from quarter to quarter primarily due to sales volume related to seasonality, variability in product mix and changes in the
competitive environment. In addition, the Company has acquired complementary businesses over the past several years and, as part of its strategy, may continue to acquire complementary businesses. The
gross profit margins of certain acquired product lines are lower than the Company's historical gross profit margin, which is adversely affecting the Company's gross profit margin. Additional
acquisitions may have a continuing adverse impact on the Company's gross profit margin. The Company is also experiencing rigorous competition in its variable message sign and weather sensing system
product lines. The Company does not believe these trends will improve in the near future.

FORWARD LOOKING STATEMENTS

Various statements made within the Management's Discussion and Analysis of Financial Condition and Results of Operations and elsewhere in this report constitute
"forward-looking statements" for purposes of the SEC's "safe harbor" provisions under the Private Securities Litigation Reform Act of 1995 and Rule 3b-6 under the Securities Exchange Act of
1934, as amended. Any statement that addresses expectations or projections about the future, including statements about the Company's strategy for growth, product development, market position,
expenditures and financial results, are forward-looking statements.

Investors
are cautioned that all forward-looking statements involve risks and uncertainties, including those detailed in the Company's public filings with the SEC, news releases and
other communications, which speak only as of the dates of those filings or communications. There can be no assurance that actual results will not differ materially from the Company's expectations.
Factors which could cause materially different results include, among others, uncertainties related to continued federal and state
funding for highways and risks related to reductions in government expenditures; the introduction and acceptance of the Company's products and services; the successful completion and integration of
acquisitions; an unfavorable change in product sales mix; seasonality along with the extent and timing of the award of large contracts; the cyclical nature of the Company's governmental markets;
competitive and pricing pressures; increasing raw material costs; excess manufacturing capacity; weather conditions; acts of war and terrorist activities; the possible impairment of intangible assets;
and general economic conditions.

ITEM 3.    Quantitative and Qualitative Disclosures about Market Risk

There have been no material changes in the information provided in Item 7.A. of the Company's Annual Report on Form 10-K for the year ended
June 30, 2002.

ITEM 4.    Controls and Procedures

Disclosure
controls and procedures are controls and other procedures that are designed to ensure that information required to be disclosed in the reports that are filed or submitted
under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission's rules and forms. Disclosure controls and
procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in the reports that are filed under the Exchange Act is accumulated and
communicated to management, including the principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. Under the supervision of
and with the participation of management, including the principal executive officer and principal financial officer, the

15

---

Company
has evaluated the effectiveness of the design and operation of its disclosure controls and procedures within 90 days of the filing date of this quarterly report, and, based on its evaluation,
our principal executive officer and principal financial officer have concluded that these controls and procedures are effective.

Although
the Company believes its pre-existing disclosure controls and procedures were adequate to enable it to comply with current disclosure obligations, the Company implemented minor
changes, primarily to formalize and document procedures already in place. The Company has also established a disclosure committee, which consists of certain members of the Company's management. The
Company is currently in the process of further reviewing, documenting and refining its disclosure controls and procedures, including internal controls and procedures, in order to enhance their
effectiveness.

There
have been no significant changes in internal controls or in other factors that could significantly affect these controls subsequent to the date of the evaluation described above,
including any corrective actions with regard to significant deficiencies and material weaknesses.
