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

         EXCEPT FOR THE HISTORICAL INFORMATION CONTAINED BELOW, THE MATTERS
DISCUSSED IN THIS SECTION ARE FORWARD-LOOKING STATEMENTS THAT INVOLVE A NUMBER
OF RISKS AND UNCERTAINTIES. OUR ACTUAL LIQUIDITY NEEDS, CAPITAL RESOURCES AND
OPERATING RESULTS MAY DIFFER MATERIALLY FROM THE DISCUSSION SET FORTH BELOW IN
THESE FORWARD-LOOKING STATEMENTS. FOR ADDITIONAL INFORMATION, REFER TO THE NOTES
TO CONSOLIDATED FINANCIAL STATEMENTS.

OVERVIEW

         Tetra Tech, Inc. is a leading provider of specialized management
consulting and technical services in three principal business areas: resource
management, infrastructure and communications. As a specialized management
consultant, we assist our clients in defining problems and developing
innovative and cost-effective solutions. Our management consulting services
are complemented by our technical services. These technical services, which
implement solutions, include research and development, applied science,
engineering and architectural design, construction management, and operations
and maintenance. Our clients include a diverse base of public and private
organizations located in the United States and internationally.

         Since our initial public offering in December 1991, we increased the
size and scope of our business and have expanded our service offerings
through a series of strategic acquisitions and internal growth. From fiscal
1991 through fiscal 2000, we generated a net revenue compounded annual growth
rate of approximately 35.8% and achieved a net income compounded annual
growth rate of approximately 37.2%.

         We derive our revenue from fees from professional services. Our
services are billed under various types of contracts with our clients,
including:

        -   fixed-price;

        -   fixed-rate time and materials;

        -   cost-reimbursement plus fixed fee; and

        -   cost-reimbursement plus fixed and award fee.

         In the course of providing our services, we routinely subcontract
services. These subcontractor costs are passed through to our clients and, in
accordance with industry practice, are included in our gross revenue. Because
subcontractor services can change significantly from project to project, we
believe net revenue, which is gross revenue less the cost of subcontractor
services, is a more appropriate measure of our performance.

         Our cost of net revenue includes professional compensation and
certain direct and indirect overhead costs such as rents, utilities and
travel. Professional compensation represents the majority of these costs. Our
selling, general and administrative (SG&A) expenses are comprised primarily
of our corporate headquarters' costs related to the executive offices,
corporate accounting, information technology, marketing, and bid and proposal
costs. These costs are generally unrelated to specific client projects. In
addition, we include amortization of certain intangible assets resulting from
acquisitions in SG&A expenses.

         We provide services to a diverse base of Federal, state and local

</TABLE>

    Our revenue and operating results fluctuate from quarter to quarter as a
result of a number of factors, such as:

    -   the seasonality of the spending cycle of our public sector clients
        and the spending patterns of our private sector clients;

    -   employee hiring and utilization rates;

    -   the number and significance of client engagements commenced and
        completed during a quarter;

    -   delays incurred in connection with an engagement;

    -   the ability of clients to terminate engagements without penalties;

    -   the size and scope of engagements;

    -   the timing and size of the return on investment capital; and

    -   general economic and political conditions.

Variations in any of these factors can cause significant variations in
operating results from quarter to quarter and could result in losses.

</TABLE>


FISCAL 2000 COMPARED TO FISCAL 1999

         NET REVENUE. Net revenue increased $166.0 million, or 38.4%, to
$598.1 million in fiscal 2000 from $432.1 million in fiscal 1999. All three
business segments and all four client sectors continued to show net revenue
increases in actual dollars. These increases were primarily attributable to
the expansion of our infrastructure services throughout the United States,
the continued expansion of new lines of service in our communications
business and companies acquired in fiscal 2000. As a percentage of net
revenue, an increase was realized in the private sector. We segregate from
our total revenue, revenue from companies acquired during the current fiscal
year as well as revenue recognized from acquired companies during the first
12 months following their respective effective dates of acquisition. Revenue
recognized from acquired companies during such first 12 months is referred to
as acquisitive revenue. Organic revenue is measured as total revenue less any
acquisitive revenue. Net revenue provided by companies acquired during fiscal
2000 totaled $32.7 million. Excluding this net revenue, we realized 30.9%
growth in our net revenue from fiscal 1999 to fiscal 2000. Acquisitive net
revenue for fiscal 2000 totaled $114.2 million. Excluding this net revenue,
we realized organic growth in our net revenue of 12.0%.

         Gross revenue increased $228.1 million, or 40.3%, to $794.6 million
in fiscal 2000 from $566.5 million in fiscal 1999. In fiscal 2000,
subcontractor costs comprised 24.7% of gross revenue compared to 23.7% for
fiscal 1999.

         COST OF NET REVENUE. Cost of net revenue increased $125.5 million,
or 38.3%, to $452.9 million in fiscal 2000 from $327.3 million in fiscal
1999. As a percentage of net revenue, cost of net revenue decreased from
75.8% in fiscal 1999 to 75.7% in fiscal 2000. Professional compensation, the
largest component of our cost of net revenue, rose as the number of our
employees increased by 677, or 12.4%, to 6,120 in fiscal 2000 from 5,443 in
fiscal 1999. However, excluding the 681 employees provided from acquired
companies, the number of our employees remained flat. Gross profit increased
$40.5 million, or 38.7%, to $145.2 million in fiscal 2000 from $104.7 million
in fiscal 1999. Included in our net revenue and gross profit was $2.00
million and $1.75 million relating to reversals of previously established
allowances for disallowed costs in fiscal 2000 and fiscal 1999, respectively.
(See Note 3 of Notes to Consolidated Financial Statements.) As a percentage
of net revenue, gross profit increased from 24.2% in fiscal 1999 to 24.3% in
fiscal 2000.

         SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. SG&A expenses,
exclusive of amortization expense, increased $20.0 million, or 45.1%, to
$64.5 million in fiscal 2000 from $44.5 million in fiscal 1999. This increase
was primarily attributable to expenses associated with the automation of our
corporate business systems and processes, business development activities and
higher administrative costs associated with acquired companies. As a
percentage of net revenue, SG&A expenses, exclusive of amortization expense,
increased to 10.8% in fiscal 2000 from 10.3% in fiscal 1999. The amortization

                                       7

<PAGE>

expense related to acquisitions increased $1.7 million, or 33.5%, to $6.5
million in fiscal 2000 from $4.8 million in fiscal 1999.

         NET INTEREST EXPENSE. Net interest expense increased $3.9 million,
or 124.1%, from $3.1 million in fiscal 1999 to $7.0 million in fiscal 2000.
This increase was primarily attributable to increased borrowings on our
credit facility in order to fund working capital and investing needs of
acquisitions as well as increase in interest rates. In fiscal 2000,
borrowings on our credit facility averaged $95.4 million compared to $44.6
million in fiscal 1999.

         INCOME TAX EXPENSE. Income tax expense increased $3.6 million, or
15.5%, to $26.8 million in fiscal 2000 from $23.2 million in fiscal 1999.
This increase was due to higher income before income taxes and a change in
our effective tax rate. During fiscal 2000, we performed an extensive review
of our current tax position and certain tax strategies which could
potentially reduce our effective tax rate. As a result of this review, we
have determined that we are entitled to certain tax credits for fiscal 2000
as well as certain prior years. These credits are primarily responsible for
the reduction in our effective tax rate to 39.8% in fiscal 2000 from 44.3% in
fiscal 1999. We expect our future effective tax rate to be approximately
42.0%.

FISCAL 1999 COMPARED TO FISCAL 1998

         NET REVENUE. Net revenue increased $134.5 million, or 45.2%, to
$432.1 million in fiscal 1999 from $297.6 million in fiscal 1998. All four
client sectors continued to show net revenue increases in actual dollars.
These increases were primarily attributable to the expansion of our
infrastructure services throughout the United States, the continued expansion
of new lines of service in our communications business and companies acquired
in fiscal 1999. As a percentage of net revenue, increases were realized in
the state and local sector, the private sector and the international sector.
Net revenue from the companies acquired in fiscal 1999 totaled $61.5 million.
Excluding the net revenue from these companies, we realized 24.5% growth in
our net revenue. Acquisitive net revenue for fiscal 1999 totaled $117.3
million. Excluding this net revenue, we realized organic growth in our net
revenue of 5.8%.

         Gross revenue increased $183.6 million, or 47.9%, to $566.5 million
in fiscal 1999 from $382.9 million in fiscal 1998. In fiscal 1999,
subcontractor costs comprised 23.7% of gross revenue compared to 22.3% for
fiscal 1998.

         COST OF NET REVENUE. Cost of net revenue increased $103.5 million,
or 46.2%, to $327.3 million in fiscal 1999 from $223.9 million in fiscal
1998. As a percentage of net revenue, cost of net revenue increased from
75.2% in fiscal 1998 to 75.8% in fiscal 1999. This increase was primarily
attributable to higher costs incurred from the acquired companies.
Professional compensation, the largest component of our cost of net revenue,
rose as the number of our employees increased by 1,781, or 48.6%, to 5,443 in
fiscal 1999 from 3,662 in fiscal 1998. Excluding the employees provided from
acquired companies, our number of employees increased by 74, or 2.0%. Gross
profit increased $31.0 million, or 42.1%, to $104.7 million in fiscal 1999
from $73.7 million in fiscal 1998. Included in our fiscal 1999 net revenue
and gross profit was $1.75 million relating to the reversal of previously
established allowances for disallowed costs. (See Note 3 of Notes to
Consolidated Financial Statements.) However, as a percentage of net revenue,
gross profit decreased from 24.8% in fiscal 1998 to 24.2% in fiscal 1999,
primarily due to lower margins of acquired companies.

         SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. SG&A expenses
increased $15.4 million, or 45.4%, to $49.3 million in fiscal 1999 from
$33.9 million in fiscal 1998. This increase was primarily attributable to
additional headquarters' costs associated with centralizing corporate
functions, other corporate initiatives, costs associated with year 2000
compliance, as well as additional amortization expense relating to acquired
companies. As a percentage of net revenue, SG&A expenses remained at

                                       8

<PAGE>

11.4%. The amortization expense related to acquisitions increased $1.8
million, or 63.1%, to $4.8 million in fiscal 1999 from $3.0 million in fiscal
1998.

         NET INTEREST EXPENSE. Net interest expense increased $1.2 million,
or 64.1%, from $1.9 million to $3.1 million from fiscal 1998 to fiscal 1999.
This increase was primarily attributable to the financing and working capital
needs of certain acquisitions.

         INCOME TAX EXPENSE. Income tax expense increased $7.3 million, or
45.6%, to $23.2 million in fiscal 1999 from $15.9 million in fiscal 1998.
This increase was due to higher income before income taxes and an increase in
our effective tax rate from 43.6% in fiscal 1998 to 44.3% in fiscal 1999.
This increase was primarily attributable to increased amounts of
non-deductible goodwill resulting from our business acquisitions.

UNAUDITED QUARTERLY OPERATING RESULTS
         The following tables set forth certain unaudited quarterly operating
results for each of our last three fiscal years ended October 1, 2000,
October 3, 1999 and October 4, 1998. This data is also expressed as a
percentage of net revenue for the respective quarters. The information has
been derived from unaudited consolidated financial statements that, in our
opinion, reflect all adjustments, consisting only of normal recurring
adjustments, necessary for a fair presentation of such quarterly information.
The operating results for any quarter are not necessarily indicative of the
results to be expected for any future period.

LIQUIDITY AND CAPITAL RESOURCES

         As of October 1, 2000, our working capital was $154.3 million, an
increase of $68.0 million from $86.3 million on October 3, 1999, of which
cash and cash equivalents totaled $7.6 million at October 1, 2000. In fiscal
2000, $12.2 million was used in operating activities and $42.3 million was
used in investing activities, of which $27.5 million was related to business
acquisitions. In fiscal 1999, $30.3 million was provided by operating
activities and $57.7 million was used in investing activities, of which $50.7
million was related to business acquisitions. In both fiscal years 2000 and
1999, cash provided by/used in operating activities was affected by the
structure of certain transactions. One of our acquisition structures is to
assign accounts receivable to the former owners at the time of the
transaction in lieu of cash consideration. This structure allows us to reduce
our cash used in investing activities. However, cash must be invested in
future periods to finance the working capital needs of the acquired company.
In fiscal 2000, in the EWS and DCI acquisitions, accounts receivable in the
aggregate amount of $3.9 million were assigned to the former owners.
Collections on assigned receivables totaled $10.7 million. If we had not
assigned these receivables at the time of acquisition, cash used in operating
activities could have been $1.5 million. In fiscal 1999, in the BAHA
Communications, Inc. and Cosentini Associates, Inc. acquisitions, accounts
receivable in the aggregate amount of $19.4 million were assigned to the
former owners. Collections on these receivables during fiscal 1999 totaled
$9.3 million. If we had not assigned these receivables at the time of
acquisition, cash provided by operating activities in fiscal 1999 could have
been $39.6 million. Our capital expenditures during fiscal years 2000 and
1999 were approximately $14.7 million and $7.0 million, respectively. Capital
expenditures were primarily for the replacement of field equipment, the
enhancement of computer equipment and office expansion.

         We have a credit agreement with a bank (the "Credit Agreement")
which provides us with a revolving credit facility (the "Facility") of $150.0
million. The Facility matures on March 17, 2005 or earlier at our discretion
upon payment in full of loans and other obligations. Throughout fiscal 2000,
maximum borrowings under the Facility were $128.5 million. At October 1,
2000, borrowings and standby letters of credit totaled $110.0 million and
$1.7 million, respectively.

         In conjunction with our investment strategy, we continuously
evaluate the marketplace for strategic acquisition opportunities. Once an
opportunity is identified, we examine the effect an acquisition may have on
the business environment, as well as on our results of operations. We proceed
with an acquisition if we determine that the acquisition is anticipated to
have an accretive effect on future operations or could expand our service
offerings. As successful integration and implementation are essential to
achieve favorable results, no assurances can be given that all acquisitions
will provide accretive results. Our strategy is to position ourselves to
address existing and emerging markets. We view acquisitions as a key
component of our growth strategy, and we intend to use both cash and our
securities, as we deem appropriate, to fund such acquisitions.

         We believe our operations have not been and, in the foreseeable
future, are not expected to be materially adversely affected by inflation or
changing prices.

RECENTLY ISSUED FINANCIAL STANDARDS

         In June 1998, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards (SFAS) No. 133, ACCOUNTING FOR
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES, which was amended by SFAS No.
138, ACCOUNTING FOR CERTAIN DERIVATIVE INSTRUMENTS AND CERTAIN HEDGING
ACTIVITIES. These Statements required derivatives to be measured at fair
value and to be recorded as assets or liabilities on the balance sheet. The
accounting for gains or losses resulting from changes in the fair values of
those derivatives would be dependent upon the use of the derivative and
whether it qualifies for hedge accounting. These Statements are effective for
all fiscal quarters of fiscal years beginning after June 15, 2000. We will
adopt these Statements in fiscal year 2001 and believe that the adoption of
SFAS No. 133 and SFAS No. 138 will have no material impact on our results of
operations or financial position.

         In December 1999, the Securities and Exchange Commission issued
Staff Accounting Bulletin (SAB) No. 101, REVENUE RECOGNITION, which outlines
the basic criteria that must be met to recognize revenue and provides
guidance for disclosures related to revenue recognition policies. SAB No. 101
requires companies to report any changes in revenue recognition as a
cumulative change in accounting principle at the time of implementation in
accordance with Accounting Principles Board Opinion No. 20, ACCOUNTING
CHANGES. SAB No. 101, as amended, is effective no later than the fourth
quarter of fiscal years beginning after December 15, 1999. We will adopt SAB
No. 101 in fiscal year 2001. We believe our existing revenue recognition
policies and procedures are in compliance with SAB No. 101, and that the
adoption of SAB No. 101 will have no material impact on our results of
operations or financial position.

MARKET RISKS

      We do not currently utilize any material derivative financial
instruments which expose us to significant market risk. We are exposed to
cash flow risk due to interest rate fluctuations with respect to our
long-term debt. At our option, we borrow on our Facility (a) at a base rate
(the greater of the federal funds rate plus 0.50% or the bank's reference
rate) or (b) at a eurodollar rate plus a margin which ranges from 0.75% to
1.25%. Borrowings at the base rate have no designated term and may be repaid
without penalty anytime prior to the Facility's maturity date. Borrowings at
a eurodollar rate have a term no less than 30 days and no greater than 90
days. Typically, at the end of such term, such borrowings may be rolled over
at our discretion into either a borrowing at the base rate or a borrowing at
a eurodollar rate with similar terms, not to exceed the maturity date of the
Facility. The Facility matures on March 17, 2005 or earlier at our discretion
upon payment in full of loans and other obligations. Accordingly, we classify
total outstanding debt between current liabilities and long-term obligations
based on anticipated payments within and beyond one year's period of time. We
presently anticipate repaying $26.0 million of our long-term obligations in
fiscal 2001. Assuming we pay our long-term debt in the amounts of $26.0
million, $31.0 million, $37.0 million and $17.5 million for the next four
years ratably throughout each year, and our average interest rate on our
long-term debt increases or decreases by one percentage point, our interest
expense could increase or decrease by $0.9 million, $0.6 million, $0.3
million and $0.1 million in fiscal 2001, 2002, 2003 and 2004, respectively.
However there can be no assurance that we will, or will be able to, repay our
debt in the prescribed manner or obtain alternate financing. We could incur
additional debt under this credit facility or our operating results could be
worse than we expect.

                          INDEPENDENT AUDITORS' REPORT



Tetra Tech, Inc.:

         We have audited the accompanying consolidated balance sheets of
Tetra Tech, Inc. and its subsidiaries as of October 1, 2000 and October 3,
1999, and the related consolidated statements of income, stockholders'
equity, and cash flows for each of the three years in the period ended
October 1, 2000. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

         We conducted our audits in accordance with auditing standards
generally accepted in the United States of America. Those standards require
that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. An audit also includes assessing the
accounting principles used and significant estimates made by management, as
well as evaluating the overall financial statement presentation. We believe
that our audits provide a reasonable basis for our opinion.

         In our opinion, such consolidated financial statements present
fairly, in all material respects, the financial position of Tetra Tech, Inc.
and its subsidiaries as of October 1, 2000 and October 3, 1999, and the
results of their operations and their cash flows for each of the three years
in the period ended October 1, 2000 in conformity with accounting principles
generally accepted in the United States of America.

                                TETRA TECH, INC.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                       FISCAL YEARS ENDED OCTOBER 1, 2000,
                       OCTOBER 3, 1999 AND OCTOBER 4, 1998

1.       SIGNIFICANT ACCOUNTING POLICIES

         BUSINESS - Tetra Tech, Inc. (the "Company") provides specialized
management consulting and technical services in three principal business
areas: resource management, infrastructure and communications. The Company's
management consulting services are complemented by its technical services.
These technical services, which implement solutions, include research and
development, applied science, engineering and architectural design,
construction management, and operations and maintenance.

         PRINCIPLES OF CONSOLIDATION - The consolidated financial statements
include the accounts of the Company, its wholly-owned subsidiaries and its
majority-owned subsidiary Tetra Tech Canada Ltd. All significant intercompany
balances and transactions have been eliminated in consolidation.

         FISCAL YEAR - The Company reports results of operations based on 52-
or 53-week periods ending near September 30. Fiscal years 2000 and 1999
contained 52 weeks. Fiscal year 1998 contained 53 weeks.

         CONTRACT REVENUE AND COSTS - In the course of providing its
services, the Company routinely subcontracts for services. These costs are
passed through to clients and, in accordance with industry practice, are
included in the Company's gross revenue. Because subcontractor services can
change significantly from project to project, changes in gross revenue may
not be indicative of business trends. Accordingly, the Company also reports
net revenue, which is gross revenue less the cost of subcontractor services.
Contract revenue and contract costs on both cost-type and fixed-price-type
contracts are recorded using the percentage-of-completion (cost-to-cost)
method. Under this method, contract revenue on long-term contracts is
recognized in the ratio that contract costs incurred bear to total estimated
costs. Costs and income on long-term contracts are subject to revision
throughout the lives of the contracts and any required adjustments are made
in the period in which the revisions become known. Losses on contracts are
recorded in full as they are identified.

         Selling, general and administrative costs are expensed in the period
incurred.

         Net revenue under Federal government contracts and subcontracts
accounted for approximately 29.1%, 39.1% and 48.7% of net revenue for the fiscal
years ended October 1, 2000, October 3, 1999 and October 4, 1998, respectively.

         CASH AND CASH EQUIVALENTS - Cash equivalents include all investments
with initial maturities of 90 days or less.

         PROPERTY AND EQUIPMENT - Property and equipment are recorded at cost
and are depreciated over their estimated useful lives using the straight-line
method. Expenditures for maintenance and repairs are expensed as incurred.

         Generally, estimated useful lives range from three to ten years for
equipment, furniture and fixtures. Leasehold improvements are amortized on a
straight-line basis over the shorter of their estimated useful lives or the
remaining terms of the leases.

                                      18

<PAGE>


         LONG-LIVED ASSETS - Management's policy regarding long-lived assets
is to evaluate the recoverability of its assets when the facts and
circumstances suggest that the assets may be impaired. This assessment is
performed based on the estimated undiscounted cash flows compared with the
carrying value of the assets. If the future cash flows (undiscounted and
without interest charges) are less than the carrying value, a writedown would
be recorded to reduce the related asset to its estimated fair value.

         Intangible assets as of October 1, 2000 and October 3, 1999 consist
principally of goodwill resulting from business acquisitions which is being
amortized over periods ranging from 15 to 30 years. The accumulated
amortization of intangible assets as of October 1, 2000 and October 3, 1999
was $17.8 million and $11.3 million, respectively.

         INCOME TAXES - The Company files a consolidated federal income tax
return and combined California franchise tax reports, as well as other
returns which are required in the states in which the Company does business,
which include the Company and its subsidiaries. Income taxes are recognized
for (a) the amount of taxes payable or refundable for the current period, and
(b) deferred income tax assets and liabilities for the future tax
consequences of events that have been recognized in the Company's financial
statements or income tax returns. The effects of income taxes are measured
based on enacted tax laws and rates.

         EARNINGS PER SHARE - Basic Earnings Per Share (EPS) excludes
dilution and is computed by dividing the income available to common
stockholders by the weighted average number of common shares outstanding for
the period. Diluted EPS is computed by dividing income available to common
stockholders by the weighted average number of common shares outstanding and
dilutive potential common shares. The Company includes as potential common
shares the weighted average number of shares of exchangeable stock of a
subsidiary, the weighted average number of shares of redeemable preferred
stock and the weighted average dilutive effects of outstanding stock options.
The exchangeable stock of a subsidiary is non-voting and is exchangeable on a
one to one basis, as adjusted for stock splits and stock dividends subsequent
to the original issuance, for the Company's common stock. The redeemable
preferred stock had voting and dividend rights substantially similar to those
of common. The redeemable preferred stock outstanding at September 28, 1997
was converted to common stock during the fiscal year ended October 4, 1998.

         FAIR VALUE OF FINANCIAL INSTRUMENTS - The carrying amounts of cash
and cash equivalents, accounts receivable, unbilled receivables and accounts
payable approximate fair value because of the short maturities of these
instruments. The carrying amount of the revolving credit facility and other
long-term debt approximates fair value because the interest rates are based
upon variable reference rates.

         CONCENTRATION OF CREDIT RISK - Financial instruments which subject
the Company to credit risk consist primarily of cash and cash equivalents,
accounts receivable and unbilled receivables. The Company places its
temporary cash investments with high credit quality financial institutions
and, by policy, limits the amount of investment exposure to any one financial
institution. As of October 1, 2000, approximately 10.2% of accounts
receivable was due from various agencies of the Federal government. The
remaining accounts receivable are generally diversified due to the large
number of organizations comprising the Company's client base and their
geographic dispersion. The Company performs ongoing credit evaluations of its
clients and maintains an allowance for potential credit losses.

         USE OF ESTIMATES - The preparation of financial statements in
conformity with accounting principles generally accepted in the United States
of America 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

                                     19

<PAGE>


financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.

         ACCOUNTING PRONOUNCEMENTS - In June 1998, the Financial Accounting
Standards Board issued Statement of Financial Accounting Standards (SFAS)
No. 133, ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES, which
was amended by SFAS No. 138, ACCOUNTING FOR CERTAIN DERIVATIVE INSTRUMENTS
AND CERTAIN HEDGING ACTIVITIES. These Statements required derivatives to be
measured at fair value and to be recorded as assets or liabilities on the
balance sheet. The accounting for gains or losses resulting from changes in
the fair values of those derivatives would be dependent upon the use of the
derivative and whether it qualifies for hedge accounting. These Statements
are effective for all fiscal quarters of fiscal years beginning after June
15, 2000. The Company will adopt these Statements in fiscal year 2001 and
believe that the adoption of SFAS No. 133 and SFAS No. 138 will have no
material impact on its results of operations or financial position.

         In December 1999, the Securities and Exchange Commission issued
Staff Accounting Bulletin (SAB) No. 101, REVENUE RECOGNITION, which outlines
the basic criteria that must be met to recognize revenue and provides
guidance for disclosures related to revenue recognition policies. SAB No. 101
requires companies to report any changes in revenue recognition as a
cumulative change in accounting principle at the time of implementation in
accordance with Accounting Principles Board (APB) Opinion No. 20, ACCOUNTING
CHANGES. SAB No. 101, as amended, is effective no later than the fourth
quarter of fiscal years beginning after December 15, 1999. The Company will
adopt SAB No. 101 in fiscal year 2001. The Company believes its existing
revenue recognition policies and procedures are in compliance with SAB No.
101, and that the adoption of SAB No. 101 will have no material impact on its
results of operations or financial position.

         All of the acquisitions above have been accounted for as purchases
and accordingly, the purchase prices of the businesses acquired have been
allocated to the assets and liabilities acquired based upon their fair
values. The excess of the purchase cost of the acquisitions over the fair
value of the net assets acquired was recorded as goodwill and is included in
Intangible Assets - Net in the accompanying condensed consolidated balance
sheets. The Company historically valued stock exchanged in acquisitions based
on extended restriction periods, high volatility in the trading price of the
Company's common stock and other economic factors specific to the Company's
circumstances. During the first three fiscal quarters of fiscal 2000 and all
of fiscal 1999 and fiscal 1998, stock exchanged in acquisitions was
discounted by 15%. The results of operations of each of the companies
acquired have been included in the Company's financial statements from the
effective acquisition dates.

         The effect of unaudited pro forma operating results of the LCI, ENG,
ESA, DCI and BTL acquisitions, had they been acquired on October 5, 1998, is
not material.

         The following table presents summarized unaudited pro forma
operating results assuming that the Company had acquired MFG, CPC, DCC, BCI,
UCC, ASL, CAA, PDR, EUC, EWS, FHC and RAI on October 5, 1998:

</TABLE>

         The accounts receivable valuation allowance includes amounts to
provide for doubtful accounts and for the potential disallowance of billed
and unbilled costs. The Company's contracts with the Federal government are
subject to audit by the government, primarily the Defense Contract Audit
Agency (DCAA), which reviews the Company's overhead rates, operating systems
and cost proposals. During the course of its audit, the DCAA may disallow
costs if it determines that the Company improperly accounted for such costs
in a manner inconsistent with Cost Accounting Standards. Historically, the
Company has not had any material cost disallowances by the DCAA as a result
of audit, except for disallowances of acquired receivables as further
described. There can be no assurance that DCAA audits will not result in
material cost disallowances in the future.

         On September 15, 1995, the Company acquired Tetra Tech EM Inc. (EMI)
which contracts with the Federal government. At the time of acquisition,
audits had not been performed for years beyond 1986 and reserves for
disallowances relating to those unaudited years were adjusted to reflect the
estimated ultimate disallowances relating to those receivables. As of October
3, 1999, audits and negotiations relating to the EMI contracts for years 1987
through 1995 were complete, and cost disallowances as a result of these
audits totaled approximately $4.4 million. Beyond the $4.4 million in cost
disallowances, there remained uncollected receivables of $2.1 million.
Although it was determined that the Company was entitled to payments,
collectibility of such amounts was not assured as each Federal agency must
obtain separate funding approval. The reserves established for these
receivables exceeded the disallowances and the uncollected amounts by $1.75
million. Accordingly, this amount was taken into income in fiscal 1999.
During fiscal 2000, the Company collected $2.0 million and reversed
previously established reserves related to these receivables. As of October
1, 2000, substantially all of these outstanding receivables have been
collected and all reserves relating to these receivables have been reversed.

         Allowances to provide for doubtful accounts have been determined
through reviews of specific amounts determined to be uncollectible, plus a
general allowance for other amounts for which some

                                      23

potential loss is determined to be probable based on current events and
circumstances. Given the above, management believes that the resolution of
these matters will not have a material adverse effect on the Company's
financial position or results of operations.

         As of October 1, 2000, the Company had approximately $4.2 million
under retainage provisions of contracts.

4.       INCOME TAXES

5.       LONG-TERM OBLIGATIONS

         The Company has a credit agreement (as amended, the "Credit
Agreement") with a bank to support its working capital and acquisition needs.
The Credit Agreement provides a revolving credit facility of $150.0 million
and matures on March 17, 2005 or earlier at the discretion of the Company
upon payment in full of loans and other obligations.

         Interest on borrowings under the Credit Agreement is payable at the
Company's option (a) at a base rate (the greater of the federal funds rate
plus 0.50% or the bank's reference rate) as defined in the Credit Agreement
or (b) at a eurodollar rate plus a margin which ranges from 0.75% to 1.25%.
The weighted average interest rate on outstanding borrowings under the Credit
Agreement at October 1, 2000 was 7.71%.

         Borrowings under the Credit Agreement are secured by the Company's
accounts receivable and the stock of the Company's subsidiaries.

         The Credit Agreement contains various covenants including, but not
limited to, restrictions related to tangible net worth, net income,
additional indebtedness, asset sales, mergers and acquisitions, creation of
liens, and dividends on capital stock (other than stock dividends).

         As of October 1, 2000, outstanding borrowings totaled $110.0 million
and standby letters of credit totaled $1.7 million.

         At October 1, 2000, approximately $1.5 million of additional debt
existed from acquired companies. The weighted average interest rate on these
outstanding borrowings at October 1, 2000 was 7.99%. This debt is primarily
related to pre-acquisition borrowings to facilitate equipment purchases. The
Company intends to repay these amounts prior to the end of their term and
terminate all such agreements.

6.       STOCKHOLDERS' EQUITY

         In February 1999, the Company, along with certain selling
stockholders, offered a total of 3,968,750 shares of its common stock through
a public offering. The Company offered 1,250,000 shares and received
approximately $22.2 million in net proceeds which were used for the partial
repayment of outstanding indebtedness under the Company's revolving credit
facility.

         In connection with the ENG and SGOC acquisitions, the Company issued
an aggregate of 953,960 shares of exchangeable stock of its subsidiary, Tetra
Tech Canada Ltd. (the "Exchangeable Shares"), a corporation existing under
the laws of the Province of Ontario, Canada. The Exchangeable Shares are
non-voting but carry exchange rights under which a holder of Exchangeable
Shares is entitled, at any time after five months from the date of issue of
the Exchangeable Shares, to require the Company to redeem all or any part of
the Exchangeable Shares for an amount per share equal to (a) the current
market price of a share of the Company's common stock, which shall be
satisfied in full by the Company's delivery to such holder of one share of
its common stock for each Exchangeable Share presented and surrendered, plus
(b) a dividend amount or dividend shares, if any. The Exchangeable Shares
cannot be put back to the Company for cash.

         Pursuant to the Company's 1989 Stock Option Plan, key employees may
be granted options to purchase an aggregate of 1,192,090 shares of the
Company's common stock at prices ranging from 85% to 100% of the market value
on the date of grant. All options granted to date by the Company have been at
100% of the market value as determined by the Board of Directors at the date
of grant. These options

                                      25

<PAGE>

become exercisable beginning one year from date of grant, become fully vested
in four years and terminate ten years from the date of grant.

         The Company also has a 1992 Incentive Stock Plan under which key
employees may be granted options to purchase an aggregate of 5,761,718 shares
of the Company's common stock at prices not less than the market value on the
date of grant. From such date of grant, these options become exercisable
after one year, are fully vested no later than five years after grant and
terminate no later than ten years after grant.

         Pursuant to the Company's 1992 Stock Option Plan for Nonemployee
Directors, non-employee directors may be granted options to purchase an
aggregate of 143,047 shares of the Company's common stock at prices not less
than the market value on the date of grant. These options vest and become
exercisable when, and only if, the optionee continues to serve as a director
until the Annual Meeting following the year in which the options were granted.

         The Company also has an Employee Stock Purchase Plan (the "Purchase
Plan") which provides for the granting of Purchase Rights to purchase common
stock to regular full and part-time employees or officers of the Company and
its subsidiaries. Under the Purchase Plan, shares of common stock will be
issued upon exercise of the Purchase Rights. Under the Purchase Plan, an
aggregate of 1,098,632 shares may be issued pursuant to the exercise of
Purchase Rights. The maximum amount that an employee can contribute during a
Purchase Right Period is $4,000, and the minimum contribution per payroll
period is $25.

         Under the Purchase Plan, the exercise price of a Purchase Right will
be the lesser of 100% of the fair market value of such shares on the first
day of the Purchase Right Period or 85% of the fair market value on the last
day of the Purchase Right Period. For this purpose, the fair market value of
the stock is its closing price as reported on the Nasdaq Stock Market on the
day in question.

         During the three years in the period ended October 1, 2000, option
activity was as follows:

10.      CONTINGENCIES

         The Company is subject to certain claims and lawsuits typically
filed against the engineering and consulting professions, primarily alleging
professional errors or omissions. The Company carries professional liability
insurance, subject to certain deductibles and policy limits against such
claims. Management is of the opinion that the resolution of these claims will
not have a material adverse effect on the Company's financial position and
results of operations.

11.      OPERATING SEGMENTS

         The Company's management has organized its operations into three
operating segments: Resource Management, Infrastructure, and Communications.
The Resource Management operating segment provides specialized environmental
engineering and consulting services primarily relating to water quality and
water availability to both public and private organizations. The
Infrastructure operating segment provides engineering services to provide
additional development, as well as upgrading and replacement of existing
infrastructure to both public and private organizations. The Communications
operating segment provides a comprehensive set of services including network
planning, engineering, site acquisition, construction and construction
management, and operations and maintenance services to telecommunications
companies, wireless service providers and cable operators. Management has
established these operating segments based upon the services provided, the
different marketing strategies, and the specialized needs of the clients. The
Company accounts for inter-segment sales and transfers as if the sales and
transfers were to third parties, that is, by applying a negotiated fee onto
the cost of the services performed. Management evaluates the performance of
these operating segments based upon their respective income from operations
before the effect of any acquisition-related amortization and any fee from
inter-segment sales and transfers.

         The following tables set forth (in thousands) summarized financial
information on the Company's reportable segments:
