                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                               September 30, 1998


1.    The consolidated balance sheet at September 30, 1998 and the consolidated
      statements of operations and cash flows for the three months ended
      September 30, 1998 and 1997 are unaudited, but in the opinion of the
      Company, include all adjustments, consisting only of normal recurring
      accruals, necessary for a fair presentation of the results for the interim
      periods. The results of operations for the three months ended September
      30, 1998 are not necessarily indicative of the results to be expected for
      the full fiscal year. Certain footnote disclosures usually included in
      financial statements prepared in accordance with generally accepted
      accounting principles have been omitted. It is suggested that these
      financial statements be read in conjunction with the financial statements
      and notes thereto included in the Company's Annual Report to Shareholders
      for the fiscal year ended June 30, 1998.

2.    Earnings per share is computed in accordance with the provisions of
      Statement of Financial Standards No. 128, Earnings per Share. Basic
      earnings per share is based upon the weighted average common shares
      outstanding. Diluted earnings per share reflect the potential dilutive
      effect of outstanding stock options and warrants.

3.    The components of inventories were as follows:

                               TRC COMPANIES, INC.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  RESULTS OF OPERATIONS AND FINANCIAL CONDITION

                 Three Months Ended September 30, 1998 and 1997

Overview

TRC Companies, Inc. provides a broad range of environmental management,
engineering and remediation services to industry and government.

Results of Operations

The Company, in the course of providing its services, routinely subcontracts
drilling, laboratory analyses, construction equipment and other specialized
services. These costs are passed directly through to clients and, in accordance
with industry practice, are included in gross revenue. Because subcontractor
costs and direct charges can change significantly from project to project, the
Company also considers net service revenue as a measure of performance.

In July 1998, the Company completed the sale of its instrumentation business
which resulted in a gain that was not material. Management's discussion and
analysis of revenue and operating costs and expenses for the three months ended
September 30, 1998, is compared to the same period last year on a proforma basis
with the results of the instrumentation business excluded. Summarized
information for the three months ended September 30, 1998, the same period of
last year on a proforma basis with the results of the instrumentation business
excluded, and as previously reported for such period follows:

Gross revenue increased by 9.8% during the three months ended September 30, 1998
to $18.4 million, from $16.8 million in the same period last year. Net service
revenue increased by 5.6% during the three months ended September 30, 1998 to
$12.9 million, from $12.2 million in the same period last year. The increase in
revenue resulted primarily from continued growth in core businesses as the
market for the Company's services improves.

Direct labor and fringe benefit costs increased by 9.1% during the three months
ended September 30, 1998, as compared to the same period last year, primarily
due to the increase in revenue. Indirect costs and expenses decreased by 5.6%
during the three months ended September 30, 1998, as compared to the same period
last year. This improvement was primarily due to the continuation of programs to
increase staff utilization and reduce operational overhead.

General and administrative expenses decreased by 11.6% during the three months
ended September 30, 1998, as compared to the same period last year. This
decrease was the direct result of cost reduction efforts undertaken since the
fourth quarter of fiscal 1997.

Depreciation and amortization expense decreased by 5.2% during the three months
ended September 30, 1998, as compared to the same period last year. This
decrease was due to the comparative reduction in capital expenditures over the
last several fiscal years, combined with the effect of other equipment which
became fully depreciated.

The Company reported income from operations of $.9 million for the three months
ended September 30, 1998, up from $.3 million in the same period last year. The
continued improvement in operating performance was primarily due to the increase
in revenue and reductions in operational overhead.


                                      -8-


Interest expense decreased by 46.1% during the three months ended September 30,
1998, as compared to the same period last year. This decrease resulted primarily
from lower levels of debt outstanding.

The provisions for federal and state income taxes reflect an effective rate of
approximately 38% for the three months ended September 30, 1998 and 1997. The
Company believes that there will be sufficient taxable income in future periods
to enable utilization of the deferred tax benefits.

Impact of Inflation

The Company's operations have not been materially affected by inflation or
changing prices because of the short-term nature of many of its contracts, and
the fact that most contracts of a longer term are subject to adjustment or have
been priced to cover anticipated increases in labor and other costs.

Liquidity and Capital Resources

The Company relies on cash provided by operations and borrowings based upon the
strength of its balance sheet to fund operations. The Company's liquidity is
assessed in terms of its overall ability to generate cash to fund its operating
and investing activities, and to reduce debt. Of particular importance in the
management of liquidity are cash flows generated from operating activities,
acquisitions, capital expenditure levels and an adequate bank line of credit.

Cash flows used in operating activities during the three months ended September
30, 1998 were approximately $2 million. The cash generated by net income and the
non-cash charges against income for depreciation and amortization was offset by
growth in accounts receivable and the timing of payments to subcontractors
associated with the growth in revenue in the current and prior three month
periods, and by the increase in prepaid expenses relative to the fiscal 1999
liability insurance program.

Investing activities provided approximately $2.5 million during the three months
ended September 30, 1998 consisting of approximately $2.8 million from the sale
of the Company's instrumentation business in July 1998, partially offset by
capital expenditures for equipment to support business growth of approximately
$.2 million. The Company expects to make capital expenditures of approximately
$.5 million during the remainder of fiscal 1999.

The Company maintains a bank financing arrangement to assist in funding various
operating and financing activities. The Company has available a $10 million
revolving credit facility secured by accounts receivable which expires July
2001. Borrowings under the agreement bear interest at the bank's base rate or
the Eurodollar rate plus 1 3/4% The agreement requires the Company to meet
certain financial ratios. At September 30, 1998, outstanding borrowings pursuant
to the agreement were $2.6 million, at an average interest rate of 7.6%. The
Company intends to repay the outstanding balance over the next several months
from available cash flow.


                                      -9-


At September 30, 1998, the Company had outstanding a $3,500,000 subordinated
note due July 1, 1999, issued in March 1994 in connection with the acquisition
of Environmental Solutions, Inc. and subsequently amended in July 1997. Interest
on the note accrues at the greater of the interest rate paid on the Company's
bank debt or 7 3/4%. The Company also had outstanding at September 30, 1998 a
$.5 million 7 3/4% subordinated note issued in connection with the purchase of
Hydro-Geo Consultants, Inc. in March 1998. The note is repayable in five equal
installments beginning in March 1999.

The Company expects to increase its available cash flow over the remainder of
fiscal 1999, primarily from operations and from reductions in working capital
derived mainly from the collection of accounts receivable. The cash generated
from operations, the cash on hand at September 30, 1998 and available borrowings
under the bank line of credit will be sufficient to meet the Company's cash
requirements for the remainder of fiscal 1999.

Year 2000 Compliance

The Company recognizes the need to ensure that its critical management,
financial and operating systems will recognize and process transactions for the
year 2000 and beyond. As a result, all computer systems and applications are
being reviewed and, where appropriate, detailed plans have been, or are being,
developed and implemented on a schedule intended to permit the Company's systems
to be fully compliant with year 2000 requirements.

Systems critical to our business operations which have been identified as non
year 2000 compliant are either being replaced or upgraded through program
modifications. Our objective is to have our upgraded and replaced systems
operational by June 30, 1999. In addition to our in-house efforts, we are asking
certain vendors, major customers, service suppliers, communication providers,
banks and other financial institutions whose systems failures could have a
significant impact on our business operations to verify their year 2000
readiness.

The costs specific to the year 2000 issue are not expected to have a material
impact on the Company's future operating results, financial condition or cash
flows. Although the Company expects to be fully year 2000 compliant on a timely
basis, if the Company's critical suppliers and customers do not address this
issue successfully, year 2000 issues could potentially have a material impact on
the Company's operations and financial condition.

The Company is currently developing contingency plans to be implemented as part
of its efforts to identify and mitigate any year 2000 issues. These plans will
be completed by June 30, 1999.

New Accounting Standards

In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 131, Disclosures about Segments of an
Enterprise and Related Information, which establishes new standards for
reporting information about operating segments in annual and interim financial
statements. The standard also requires descriptive information about the way the
operating segments are determined, the products and services provided by the
segments and the nature of differences between reportable segment measurements
and those used for the consolidated enterprise. This standard will be effective
for the Company in fiscal 1999. 


                                      -10-


Adoption in interim financial statements is not required until the year after
initial adoption; however, comparative prior period information is required.
Adoption is not expected to have a material impact on the financial position or
results of operations of the Company.

Forward-Looking Statements

This report contains forward-looking statements that describe the Company's
business prospects. These statements involve risks and uncertainties including,
but not limited to, regulatory uncertainty, government funding, level of demand
for the Company's services, industry-wide competitive factors and political,
economic or other conditions. Furthermore, market trends are subject to changes
which could adversely affect future results.
