              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

                                 March 31, 2002
                      (in thousands, except per share data)

1.   The condensed consolidated balance sheet at March 31, 2002 and the
     consolidated statements of operations for the three and nine months ended
     March 31, 2002 and 2001 and the condensed consolidated statements of cash
     flows for the nine months ended March 31, 2002 and 2001 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 June 30, 2001 condensed consolidated balance
     sheet data was derived from the audited financial statements but does not
     include all disclosures required by accounting principles generally
     accepted in the United States of America. Certain footnote disclosures
     usually included in financial statements prepared in accordance with
     accounting principles generally accepted in the United States of America
     have been omitted. These financial statements should be read in conjunction
     with the financial statements and notes thereto included in the Company's
     Annual Report on Form 10-K, as amended, for the fiscal year ended June 30,
     2001.

     With respect to the unaudited financial information of TRC Companies, Inc.
     for the three and nine months ended March 31, 2002 and 2001, included
     herein, PricewaterhouseCoopers LLP reported that they have applied limited
     procedures in accordance with professional standards for a review of such
     information. However, their separate report dated May 8, 2002 appearing
     herein, states that they did not audit and they do not express an opinion
     on that unaudited financial information. Accordingly, the degree of
     reliance on their report on such information should be restricted in light
     of the limited nature of the review procedures applied.
     PricewaterhouseCoopers LLP is not subject to the liability provisions of
     Section 11 of the Securities Act of 1933 for their report on the unaudited
     financial information because that report is not a "report" or a "part" of
     the registration statement prepared or certified by PricewaterhouseCoopers
     LLP within the meaning of Sections 7 and 11 of the Act.

2.   In June 2001, the Financial Accounting Standards Board issued Statements of
     Financial Accounting Standards ("SFAS") No. 141, "Business Combinations",
     and SFAS No. 142, "Goodwill and Other Intangible Assets." SFAS 141 requires
     that all business combinations be accounted for under the purchase method
     and that certain acquired intangible assets in a business combination be
     recognized as assets apart from goodwill. SFAS 142 requires that ratable
     amortization of goodwill and other intangible assets with an indefinite
     life be replaced with periodic tests of impairment and that identifiable
     intangible assets other than goodwill be amortized over their useful lives.
     SFAS 141 is effective for all business combinations completed after June
     30, 2001. The Company elected to early adopt the provisions of SFAS 142
     effective July 1, 2001.

     The table below shows the effect on net income had SFAS 142 been adopted in
     prior periods.

     Unbilled Costs generally represent billable amounts recognized as revenue
     primarily in the last month of the period. Management expects that
     substantially all Unbilled Costs will be billed and collected within one
     year. The majority of Amounts Billed are expected to be collected within 60
     days from the invoice date. Retainage represents amounts billed but not
     paid by the customer which, pursuant to the contract is due at completion.

     Long-Term Insurance Receivable at March 31, 2002 and June 30, 2001 of
     $4,760 and $2,046, respectively, relate to unbilled costs on Exit Strategy
     contracts and represent amounts held by the insurance company until
     completion of certain milestones.

5.   The Company has entered into several long-term contracts under its Exit
     Strategy program under which the Company is obligated to complete the
     remediation of environmental conditions at a site for a fixed fee. The
     Company assumes the risk for remediation costs for pre-existing site
     environmental conditions and believes that through in-depth technical
     analysis, comprehensive cost estimation and creative remedial approaches it
     is able to execute pricing strategies which protect the Company's return on
     these projects. As additional protection, the Company obtains a finite risk
     cost cap insurance policy from rated insurance companies (e.g., American
     International Group) which provides coverage for cost increases arising
     from unknown or changed conditions up to a specified maximum amount
     significantly in excess of the estimated cost of remediation. Upon signing
     of the contract, the Company receives the fixed fee contract price of which
     a substantial portion is deposited in a restricted account held by the
     insurance company. The insurance company then pays the Company from the
     deposited funds as work is performed. The Company believes that it is
     adequately protected from risks on these projects and that adverse
     developments, if any, will not have a material impact on the Company's
     consolidated operating results, financial condition or cash flows.

                                       -9-

6.   One Exit Strategy contract entered into by the Company also involved the
     Company entering into a consent decree with government authorities and
     assuming the obligation for the settling responsible parties' environmental
     remediation liability for the site. The Company's expected remediation cost
     is fully funded by the contract price received and is fully insured by a
     finite risk cost cap insurance policy for amounts significantly in excess
     of the estimated cost of remediation. Accordingly, the Company has recorded
     the Environmental Remediation Liability for the site with offsetting
     recoverables from the insurance company. In general, the Insurance
     Recoverable and Environmental Remediation Liability amounts for these items
     will be equivalent and will reduce over time as this Exit Strategy project
     is completed. For example, the Long-Term Environmental Remediation
     Liability of $1,237 at March 31, 2002, equals the Long-Term Insurance
     Recoverable - Environmental Remediation of $1,237. Also, the current
     Environmental Remediation Liability of $1,866 at March 31, 2002 is matched
     by the Insurance Recoverable - Environmental Remediation of $2,005, which
     includes that liability as well as other amounts payable to the Company
     under the insurance policy.

7.   On October 15, 2001, the Company completed the acquisition of the
     SITE-Blauvelt group of companies ("SITE"). SITE is a transportation
     infrastructure firm headquartered in Mt. Laurel, New Jersey with offices in
     a number of other states. The purchase price of $22,940 (after closing
     adjustments but before contingent consideration) consisted of approximately
     870,000 shares of the Company's common stock and resulted in Goodwill of
     $18,958 being recorded in accordance with SFAS 141. Additionally,
     intangible assets acquired were recorded and are immaterial to the
     Company's financial condition. The significant assets and liabilities
     acquired were Accounts Receivable of $16,712, Debt of $5,663 and Deferred
     Income Tax Liabilities of $5,952. The Company may make additional payments
     if certain financial goals are achieved in each of the next three years.
     The acquisition has been accounted for using the purchase method of
     accounting in accordance with SFAS 141.

     In addition to the SITE acquisition, the Company completed the acquisition
     of several other companies during the nine months ended March 31, 2002. The
     gross purchase price for these acquisitions was approximately $13,390
     (before contingent consideration) consisting of a combination of cash and
     shares of the Company's common stock. As a result of these acquisitions,
     Goodwill of $10,567 was recorded in accordance with SFAS 142. Additionally,
     intangible assets acquired were recorded and are immaterial to the
     Company's financial condition. These acquisitions have also been accounted
     for using the purchase method of accounting in accordance with SFAS 141.

     The following unaudited pro forma information for the nine months ended
     March 31, 2002 and 2001 presents summarized results of operations as if
     current and prior year acquisitions had occurred at the beginning of the
     periods presented after giving effect to adjustments, including goodwill
     and intangible asset amortization, increased interest expense on
     acquisition borrowings and related income tax effects:

     The unaudited pro forma financial information may not be indicative of the
     results that would have occurred had the acquisitions taken place at the
     beginning of the periods presented, nor be indicative of the results that
     will be obtained in the future.

     The Company also made additional purchase price payments during the nine
     months ended March 31, 2002 related to acquisitions completed in the last
     several years, resulting in additional Goodwill of $8,548 being recorded in
     accordance with SFAS 142. The Company also recorded adjustments to purchase
     price allocation for an acquisition completed in fiscal 2001 resulting in
     additional Goodwill of $189.

8.   Billings in Advance of Revenue Earned represents amounts collected in
     accordance with contractual terms, in advance of when the work is
     performed. These advance payments primarily relate to the Company's Exit
     Strategy program.

9.   The Company maintains a bank financing arrangement which currently provides
     a $32,000 revolving credit facility to assist in funding various operating
     and investing activities. Borrowings under the agreement bear interest at
     the banks' base rate or the Eurodollar rate plus or minus applicable
     margins, are collateralized by all Accounts Receivable of the Company and
     are due and payable in March 2005 when the agreement expires. The agreement
     contains various covenants including, but not limited to, restrictions
     related to net worth, EBITDA, leverage, asset sales, mergers and
     acquisitions, creation of liens and dividends on common stock (other than
     stock dividends).

10.  On December 19, 2001 the Company completed a private placement of $15,000
     of a newly designated class of Preferred Stock with Fletcher International,
     Ltd., an affiliate of Fletcher Asset Management, Inc. ("Fletcher") of New
     York City. The Preferred Stock is convertible into TRC common stock at a
     conversion price of $37.66 per share. TRC also granted Fletcher the right,
     commencing on December 15, 2002 and ending on December 14, 2003, to
     purchase up to 10,000 shares of one or more additional series of Preferred
     Stock under similar terms and conditions at a price of $1,000 per share.
     The Preferred Stock issued to Fletcher has a five-year term with a 4%
     annual dividend, which is payable at TRC's option in either cash or common
     stock. TRC will have the right to redeem the Preferred Stock for cash once
     the price of its common stock reaches certain predetermined levels.
     Following 48 months of issuance, the Preferred Stock is redeemable by
     Fletcher in common stock. On the five-year expiration date, any shares of
     Preferred Stock still outstanding are to be mandatorily redeemed, at TRC's
     option, in either cash or shares of common stock. The Preferred Stock was
     recorded net of issuance costs of $419.

     common stock. The additional shares were distributed on March 5, 2002 in
     the form of a 50% stock dividend to shareholders of record on February 19,
     2002. The accompanying financial statements and notes thereto have been
     adjusted to reflect the stock split.

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

               Three and Nine Months Ended March 31, 2002 and 2001

OVERVIEW

The Company is a leading provider of technical, financial risk management and
construction services to industry and government primarily in the United States
market. The Company's main focus is in the areas of infrastructure improvements
and expansions, environmental management and power development and conservation.

RESULTS OF OPERATIONS

The Company derives its revenue from fees for providing engineering and
consulting services. The types of contracts with our customers and the
approximate percentage of net service revenue from each contract type are as
follows:

          -    Time and material                        51%
          -    Fixed price or lump sum                  32%
          -    Cost-type with various fee arrangements  17%

In the course of providing its services the Company routinely subcontracts
drilling, laboratory analyses, construction equipment and other services. These
costs are passed directly through to customers and, in accordance with industry
practice, are included in Gross Revenue. Because Subcontractor Costs and Direct
Charges can vary significantly from project to project, the Company considers
Net Service Revenue (NSR), which is Gross Revenue less Subcontractor Costs and
Direct Charges, as its primary measure of revenue growth.

The following table presents the percentage relationships of certain items in
the consolidated statements of operations to NSR:

The year-to-year NSR growth trend realized for each of the past 19 quarters has
continued for the three months ended March 31, 2002. NSR increased by 53%
to $49.0 million, compared to $32.1 million in the same period last year. For
the nine months ended March 31, 2002, NSR increased by 50% to $131.4 million,
compared to $87.9 million in the same period last year.

NSR from acquired companies is considered part of acquisition growth during the
twelve months from the date acquired. Approximately 87% and 71% of the NSR
growth for the three and nine month periods, respectively, was from
acquisitions, while as discussed below operating income growth for these same
periods was greatest from organic (existing business) activities. These
characteristics are due to:

     -    The relatively larger size of the two recently acquired companies,
          compared to the Company's typical smaller size acquisitions.
     -    The seasonality of the largest acquisition (SITE-Blauvelt), which
          added significant NSR with relatively small operating income during
          the winter period.
     -    Increased margins provided by the Company's organic business
          activities.

Management's goal continues to be to provide a reasonable balance between
organic and acquisition growth over a several year period.

Cost of Services increased 52% and 49% on a year-to-year basis during the three
and nine month periods, respectively, as a direct result of the Company's
increased revenues. However, as a percentage of NSR, Cost of Services decreased
from 81.2% to 81.1% and 81.2% to 80.7% on a year-to-year basis during the three
and nine month periods, respectively. These reductions were primarily the result
of increased margins for the services performed.

General and Administrative Expenses (G&A) increased approximately 33% and 32% on
a year-to-year basis during the three and nine month periods, respectively,
primarily from additional costs required to support the Company's growth.
However, as a percentage of NSR, G&A expenses decreased from 3.1% to 2.7% and
3.2% to 2.8% on a year-to-year basis during the three and nine month periods,
respectively. These decreases are due to the Company's ability to obtain and
manage the increased revenue without adding a proportional amount of overhead.
This decrease results in higher margins for all services performed.

Depreciation and Amortization expense decreased by approximately 9% and 13%,
respectively, during the three and nine month periods, compared to the prior
year. These decreases were primarily due to the Company's early adoption of SFAS
142, "Goodwill and Other Intangible Assets". In accordance with SFAS 142, the
Company no longer amortizes Goodwill. The decrease associated with the adoption
of SFAS 142 was, however, partially offset by an increase in depreciation
expense associated with equipment acquired through acquisitions.

Income from Operations increased from approximately $4.1 million to $7.1 million
(72%) during the three month period and from approximately $11.1 million to
$19.4 million (75%) during the nine month period as compared to the same periods
in the prior year. Approximately 56% and 66% of the increase for the three and
nine month periods, respectively, was from organic growth. The remaining 44% and
34% of the Income from Operations growth was from acquisitions completed

                                      -13-
<Page>

during the past twelve months. The improvement in operating income performance
was primarily due to:

     -    The Company's focus toward higher margin, economically driven markets;
     -    The growth in revenue, without comparable increases in overhead; and
     -    The favorable impact resulting from the adoption of SFAS 142.

The favorable organic growth percentages reflect the Company's successful
efforts to obtain higher margin revenue for its services, and management's
objective to maintain a reasonable balance between organic and acquisition
related growth.

Interest Expense decreased during the three and nine month periods, as compared
to the same periods last year, primarily due to lower average interest rates.
The Company's percentage of debt to capitalization ratio continues to remain
relatively low, reflecting management's conservative debt philosophy.

The provision for federal and state income taxes reflects an effective rate of
38.3% in the three and nine months compared to effective rates of 38% and 37.4%,
respectively, in the same periods last year. The increases were primarily due to
an increase in the federal income tax rate bracket as a result of the Company's
income growth. The Company believes that there will be sufficient taxable income
in future periods to enable utilization of available deferred income 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 primarily relies on cash from operations and financing activities,
including borrowings based upon the strength of its balance sheet, to fund
operations. As discussed below, the cash generated from operations, the cash on
hand at March 31, 2002 and available borrowings under the credit facility will
be sufficient to meet the Company's cash requirements for currently anticipated
activities. 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 flow from operating activities was $3.4 million for the three months ended
March 31, 2002. Management expects that a similar result will be realized for
the fourth fiscal quarter.

Operating cash flow for the nine months ended March 31, 2002, was $.9 million,
compared to $12.8 million for the same period last year. This variation in
year-to-year operating cash flows was primarily the result of changes in
Billings in Advance of Revenue Earned, which fluctuate primarily

                                      -14-
<Page>

depending on the number of new Exit Strategy contracts entered into during each
period. Billings in Advance of Revenue Earned primarily represents amounts
collected in accordance with contractual terms, in advance of when the work is
performed on Exit Strategy contracts. These prepayments provide the Company with
an advance source of cash for one to several years. During periods when the
amount of prepayments from new Exit Strategy contracts exceeds the amount of
revenue recognized as work is performed on the contracts, Billings in Advance of
Revenue Earned will increase and thereby provide operating cash flow. For
instance, during the nine months ended March 31, 2001, the increase in Billings
in Advance of Revenue Earned contributed $8.1 million towards the total cash
provided by operating activities. However, during periods when the amount of
revenue recognized from work performed exceeds the amount of prepayments from
new Exit Strategy contracts, Billings in Advance of Revenue Earned will decrease
and reduce operating cash flow. During the nine months ended March 31, 2002, the
decrease in Billings in Advance of Revenue Earned reduced operating cash flow by
$4.6 million.

Operating cash flows are also increased by noncash charges for Depreciation
and Amortization (i.e., $2.3 million for the nine month period ended March
31, 2002), and typically decreased by Accounts Receivable associated with the
Company's revenue growth (i.e., $5.0 million for the nine month period). Over
time, operating cash flows can be either increased or decreased by changes in
the Long-Term Insurance Receivable. For the nine month period, operating cash
flows decreased by the $2.7 million increase in the Long-Term Insurance
Receivable. Overall Accounts Receivable and Long-Term Receivable
characteristics for the Company are discussed in the following paragraphs.

Accounts Receivable includes both: (1) billed receivables associated with
invoices submitted for work previously completed and (2) unbilled receivables
(work in progress). The unbilled receivables are primarily related to work
performed in the last month of the reporting period. The magnitude of the
Accounts Receivable for a professional services company is typically evaluated
as days sales outstanding (DSO), which is calculated by dividing both current
and long-term receivables by the most recent six months average daily Gross
Revenue, adjusted to include Gross Revenue from acquired entities to the extent
it is not already included in the Company's Gross Revenue. At March 31, 2002,
the Company's DSO was approximately 115 days. DSO would have been 109 days at
March 31, 2002 if the SITE acquisition were excluded from the calculation. This
compares favorably to DSO of 112 days at June 30, 2001. Management's long-term
goal is to reduce DSO to 100-105 days.

Funding and risk management for Exit Strategy projects is frequently provided by
a finite risk cost cap insurance policy issued by the Company's insurer,
American International Group (AIG). The policy provides risk protection against
potential increases in the cost of the project. The Company generally receives
the contract price as a prepayment from its customer and a substantial portion
of that prepayment is deposited with AIG pursuant to the policy. AIG then
pays the Company from the deposited funds as work is performed. The Long-Term
Insurance Receivable is associated with amounts held by AIG for work
performed but which are currently not yet payable under the terms of the
policy. These amounts will be paid as the Company completes certain project
milestones (e.g., completion of capital improvements). The effect on periodic
operating cash flows will vary depending upon the mix of work performed but
not yet payable and amounts released.

                                      -15-
<Page>

As a result of these factors, some periods will have a high operating cash flow
to Net Income relationship. In others, this relationship will be lower. Over
longer periods the effect should tend to be normalized with an overall positive
operating cash flow trend.

Investing activities used cash of approximately $18.1 million during the nine
months ended March 31, 2002, primarily consisting of $14 million for
acquisitions and earnout payments and $3 million in capital expenditures for
additional information technology and other equipment to support business
growth. During the remainder of fiscal 2002, the Company expects to make
acquisition earnout payments of about $3.2 million and capital expenditures of
approximately $1 million.

Financing activities provided cash of approximately $19.5 million during the
nine months ended March 31, 2002 to support operating and investing activities.
The private placement of a new class of preferred stock on December 19, 2001,
provided $14.6 million (net of issuance costs) and the remaining $4.9 million
was primarily provided by net borrowings from the Company's credit facilities.
During the same period, cash increased from $.8 million at June 30, 2001 to $3.1
million at March 31, 2002.

In March 2002 the Company entered into a new banking arrangement with First
Union National Bank. The agreement provides for a revolving credit facility of
$40 million to provide flexible funding for various short-term operating and
investing activities. The initial availability under the facility is $32
million and is expected to be raised to the agreement amount of $40 million
by June 30, 2002. Borrowings under the agreement bear interest at the banks'
base rate or the Eurodollar rate plus or minus applicable margins and are due
and payable in March 2005 when the agreement expires. At March 31, 2002,
outstanding borrowings pursuant to the agreement were $25.1 million, at an
average interest rate of 3.6%.

We expect that the cash generated from operations, the cash on hand at March 31,
2002 and available borrowings under the revolving credit facility will be
sufficient to meet the Company's cash requirements for currently anticipated
activities. If in the future the Company pursues acquisitions in which the
potential cash consideration approaches or exceeds the availability of current
sources, the Company would either increase its lending facility or pursue
additional financing. The Company plans to maintain its conservative debt
philosophy.

NEW ACCOUNTING GUIDANCE

In June 2001, the Financial Accounting Standards Board issued SFAS No. 143,
"Accounting for Asset Retirement Obligations." The standard requires that legal
obligations associated with the retirement of tangible long-lived assets be
recorded at fair value when incurred and is effective July 1, 2002 for the
Company. The Company is currently reviewing the provisions of SFAS 143 to
determine if and how it applies to the Company.

In August 2001, the Financial Accounting Standards Board issued SFAS No. 144,
"Accounting for the Impairment or Disposal of Long-Lived Assets." The standard
provides guidance on the accounting for the impairment or disposal of long-lived
assets and is effective July 1, 2002 for the Company. The Company is currently
reviewing the provisions of SFAS 144 to determine if and how it applies to the
Company.

In April 2002, the Financial Accounting Standards Board issued SFAS 145,
"Rescission of FASB Statements No. 4, 44, and 64, Amendment of FASB Statement
No. 13, and Technical Corrections." The standard provides guidance on the
accounting for leases and amends other existing authoritative pronouncements
and is generally effective July 1, 2002 for the Company. The Company is
currently reviewing the provisions of SFAS 145 to determine if and how it
applies to 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.

ITEM 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company's exposure to market risk for changes in interest rates relates
primarily to borrowings under the Company's revolving credit agreement with a
commercial bank. These borrowings bear interest at variable rates and the fair
value of this indebtedness is not significantly affected by changes in market
interest rates. An effective increase or decrease of 10% in the current
effective interest rate under the revolving credit agreement would not have a
material effect on the Company's consolidated operating results, financial
condition or cash flows.
