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 THE 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 1998, we generated a net revenue compounded annual growth rate of approximately 34.2% and achieved a net income compounded annual growth rate of approximately 36.4%. We derive our gross revenues 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 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 government agencies, and private and international clients. The following table presents, for the periods indicated, the approximate percentage of our net revenue attributable to these client sectors: Percentage of Net Revenue ----------------------------------- Client Fiscal 1998 Fiscal 1997 Fiscal 1996 ------ ----------- ----------- ----------- Federal government................. 48.7% 52.3% 61.7% State and local government......... 12.7 14.8 16.6 Private............................ 35.4 29.2 20.1 International...................... 3.2 3.7 1.6 ----------- ----------- ----------- Total.............................. 100.0% 100.0% 100.0% ----------- ----------- ----------- ----------- ----------- ----------- RECENT ACQUISITIONS As a part of our growth strategy, we expect to pursue complementary acquisitions to expand our geographical reach and the breadth and depth of our service offerings. During fiscal 1998, we purchased ten companies in the following five separate transactions: - TETRA TECH NUS, INC.- In December 1997, we acquired, through our wholly-owned subsidiary Tetra Tech NUS, Inc. (NUS), the assets of certain environmental services businesses of Brown & Root, Inc. and Halliburton Corporation. The purchase was valued at approximately $25.2 million. NUS is a nationwide firm providing consulting, engineering and design services for the environmental remediation of contaminated air, water and soil conditions. - WHALEN/SENTREX LLC- In March 1998, our wholly-owned subsidiary Whalen Service Corps Inc. agreed to participate in a partnership with Sentrex Cen-Comm and ANTEC Corporation. The partnership purchased certain assets from ANTEC Corporation for a price of approximately $0.6 million. The partnership, Whalen/Sentrex LLC, a Colorado-based firm, provides nationwide design, engineering, information management and construction services to support advanced communication system upgrades to the broadband information transport industries. - C.D.C. ENGINEERING, INC.- In March 1998, we acquired C.D.C. Engineering, Inc. (CDE). The purchase was valued at approximately $1.5 million. CDE, a California-based consulting and engineering firm, specializes in civil engineering, transportation engineering, structural engineering and land surveying. - MCNAMEE, PORTER & SEELEY, INC.- In July 1998, we acquired McNamee, Porter & Seeley, Inc. (MPS). The purchase was valued at approximately $14.2 million. MPS, a Michigan-based firm, provides engineering services throughout the Midwest with expertise in the areas of water, industrial wastewater and process controls. - SENTREX GROUP OF COMPANIES- In September 1998, we acquired, through our wholly-owned subsidiary, Tetra Tech Canada Ltd., six Canadian corporations that are collectively referred to as the Sentrex Group of Companies (SGOC). The purchase was valued at approximately $19.2 million. SGOC provides engineering and technical services to the cable television, telephony and data networking industries. As a result of the SGOC acquisition, we now own 100% of Whalen/Sentrex LLC. RESULTS OF OPERATIONS The following table sets forth, for the periods indicated, certain operating information as a percentage of net revenue: Percentage Relationship to Net Revenue -------------------------------------- Fiscal Year Ended -------------------------------------- Oct. 4, Sept. 28, Sept. 29, 1998 1997 1996 ------- --------- -------- Net revenue............................. 100.0% 100.0% 100.0% Cost of net revenue..................... 75.2 73.9 75.8 ------- --------- -------- Gross profit............................ 24.8 26.1 24.2 Selling, general and administrative expenses............................. 11.4 13.2 13.2 ------- --------- -------- Income from operations.................. 13.4 12.9 11.0 Net interest income (expense)...........

Net revenue increased $106.8 million, or 56.0%, to $297.6 million in fiscal 1998 from $190.8 million in fiscal 1997. All four client sectors continued to show net revenue increases in actual dollars. These increases were attributable to increases in our existing Federal government contracts, the introduction of new lines of service in our communications business and to companies acquired in fiscal 1998. As a percentage of net revenue, increases were realized in the private sector. Net revenue from the companies acquired in fiscal 1998 totaled $72.0 million. Excluding the net revenue from these companies, we realized 18.2% growth in our net revenue. Gross revenue increased $136.2 million, or 55.2%, to $382.9 million in fiscal 1998 from $246.8 million in fiscal 1997. In fiscal 1998, subcontractor costs comprised 22.3% of gross revenue compared to 22.7% for fiscal 1997. COST OF NET REVENUE. Cost of net revenue increased $82.9 million, or 58.8%, to $223.9 million in fiscal 1998 from $141.0 million in fiscal 1997. As a percentage of net revenue, cost of net revenue increased from 73.9% in fiscal 1997 to 75.2% in fiscal 1998. This increase was primarily attributable to higher costs of Federal government contracts, as well as costs incurred in connection with the additional net revenue from the acquired companies. Professional compensation, the largest component of our cost of net revenue, rose as the number of our employees increased by 1,400, or 61.9%, to 3,662 in fiscal 1998 from 2,262 in fiscal 1997. Excluding the employees provided from acquired companies, our number of employees increased by 265, or 11.7%. Gross profit increased $24.0 million, or 48.1%, to $73.7 million in fiscal 1998 from $49.8 million in fiscal 1997. However, as a percentage of net revenue, gross profit decreased from 26.1% in fiscal 1997 to 24.8% in fiscal 1998, primarily due to a change in the relative mix of our Federal government contracts. SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. SG&A expenses increased $8.7 million, or 34.7%, to $33.9 million in fiscal 1998 from $25.2 million in fiscal 1997. This increase was primarily attributable to additional headquarters' costs associated with centralizing corporate functions as well as additional amortization expense relating to acquired companies. As a percentage of net revenue, SG&A expenses decreased from 13.2% in fiscal 1997 to 11.4% in fiscal 1998 due to operating efficiencies. The amortization expenses related to acquisitions increased $1.4 million, or 89.1%, to $3.0 million in fiscal 1998 from $1.6 million in fiscal 1997. NET INTEREST EXPENSE. Net interest expense increased from less than $0.1 million to $1.9 million from fiscal 1997 to fiscal 1998. This increase was primarily attributable to the financing and working capital needs of certain acquisitions. INCOME TAX EXPENSE. Income tax expense increased $5.6 million, or 54.2%, to $15.9 million in fiscal 1998 from $10.3 million in fiscal 1997. This increase was due to higher income before income taxes and an increase in our effective tax rate from 42.0% in fiscal 1997 to 43.6% in fiscal 1998. This increase was primarily attributable to amortization amounts which were not tax deductible. FISCAL 1997 COMPARED TO FISCAL 1996 NET REVENUE. Net revenue increased $29.8 million, or 18.5%, to $190.8 million in fiscal 1997 from $161.0 million in fiscal 1996. This increase in net revenue was primarily attributable to revenue associated with companies acquired in fiscal 1997 which totaled $24.6 million. Despite the weakened condition of the environmental industry, which was impacted by the decrease in Federal government activity, we attained a 3.2% growth in our net revenue, excluding revenue related to acquired companies. Gross revenue increased $26.7 million, or 12.1%, to $246.8 million in fiscal 1997 from $220.1 million in fiscal 1996. In fiscal 1997, subcontractor costs were 22.7% of gross revenue, compared to 26.8% for fiscal 1996. This decrease was due to the nature of the projects undertaken. COST OF NET REVENUE. Cost of net revenue increased $18.9 million, or 15.5%, to $141.0 million in fiscal 1997 from $122.1 million in fiscal 1996. This increase was primarily attributable to costs incurred in connection with the additional net revenue from the acquired companies. As a percentage of net revenue, cost of net revenue decreased from 75.8% in fiscal 1996 to 73.9% in fiscal 1997. Professional compensation, the largest component of our cost of net revenue, rose as the number of employees increased by 363, or 19.1%, to 2,262 in fiscal 1997 from 1,899 in fiscal 1996. Excluding the employees provided from acquired companies, our number of employees remained relatively flat. Gross profit increased $10.8 million, or 27.8%, to $49.8 million in fiscal 1997 from $39.0 million in fiscal 1996, primarily due to efficiencies in operations, acquisitions and higher profit margins realized in the acquired businesses in the communications industry. SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. SG&A expenses increased $4.0 million, or 18.6%, to $25.2 million in fiscal 1997 from $21.2 million in fiscal 1996. However, as a percentage of net revenue, SG&A expenses remained flat at 13.2% for fiscal 1997. The amortization of intangible assets relating to acquisitions increased $0.4 million, or 29.8%, to $1.6 million in fiscal 1997 from $1.2 million in fiscal 1996. NET INTEREST EXPENSE. Net interest expense decreased $0.8 million to less than $0.1 million in fiscal 1997 due to the reduction of the average outstanding borrowings from fiscal 1996 to fiscal 1997. INCOME TAX EXPENSE. Income tax expense increased $3.4 million, or 50.6%, to $10.3 million in fiscal 1997 from $6.9 million in fiscal 1996. Our effective tax rate increased from 40.4% in fiscal 1996 to 42.0% in fiscal 1997. This increase was primarily attributable to amortization amounts which were not tax deductible. UNAUDITED QUARTERLY OPERATING RESULTS The following tables set forth certain unaudited quarterly operating results for each of our last three fiscal years ended September 29, 1996, September 28, 1997 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.

-------- -------- -------- Net income 7.5% 6.3% 7.3% 6.7% -------- -------- -------- -------- -------- -------- -------- -------- Our revenues and operating results fluctuate from quarter to quarter as a result of a number of factors, such as: (1) the seasonality of the spending cycle of our public sector clients, notably the Federal government; (2) employee hiring and utilization rates; (3) the number and significance of client engagements commenced and completed during a quarter; (4) delays incurred in connection with an engagement; (5) the ability of clients to terminate engagements without penalties; (6) the size and scope of engagements; (7) the timing and size of the return on investment capital; and (8) 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. LIQUIDITY AND CAPITAL RESOURCES We expect that internally generated funds, our existing cash balances, and availability under the Credit Agreement will be sufficient to meet our capital requirements through the end of fiscal 1999. As of October 4, 1998, our working capital was $77.0 million, an increase of $34.5 million from $42.5 million on September 28, 1997, of which cash and cash equivalents totaled $4.9 million. In fiscal 1998, we augmented cash used in operations with borrowings under our credit facility. In fiscal 1998, $6.6 million was used in operating activities and $41.3 million was used in investing activities, of which $37.8 million was related to business acquisitions. In fiscal 1997, we generated $1.1 million from operating activities and used $3.8 million in investing activities, of which $1.2 million was related to business acquisitions. The decreases in cash provided from operating activities in fiscal 1998 and fiscal 1997 primarily resulted from the payment of liabilities assumed in connection with the fiscal 1998 acquisitions of approximately $6.4 million, as well as the acquisitions of Whalen & Company, Inc. in fiscal 1997 and McNamee, Porter & Seeley, Inc. in fiscal 1998. In these acquisitions we agreed that we would not acquire the accounts receivable. As a result, we experienced a lag in cash flow to fund the business' operations. As an ongoing effort, we attempt to increase our efficiencies in the timing of billings and the collection of receivables. Our capital expenditures during fiscal years 1998, 1997, and 1996 were approximately $3.5 million, $2.6 million and $2.4 million, respectively. The expenditures were primarily for computer equipment, leasehold improvements and office expansion. We have a credit agreement with a bank (the "Credit Agreement") which, as of October 4, 1998, provided us with a revolving credit facility (the "Facility") of $70.0 million. The Credit Agreement provides for mandatory reductions of $5.0 million on December 15, 1998 and December 15, 1999. We amended the Credit Agreement during fiscal 1998 in order to accommodate the fiscal 1998 acquisitions, as well as to position ourselves to pursue future acquisitions. The Facility matures on December 15, 2000 or earlier at our discretion upon payment in full of loans and other obligations. Throughout fiscal 1998, maximum borrowings under the Facility were $49.0 million. At October 4, 1998, borrowings and standby letters of credit totaled $47.0 million and $2.2 million, respectively. 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. However, 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, we do not expect to be materially adversely affected by inflation or changing prices. RECENTLY ISSUED FINANCIAL STANDARDS In February 1997, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standard (SFAS) No. 128, EARNINGS PER SHARE, which we adopted in fiscal year 1998. The Statement replaces the presentation of primary EPS with a presentation of basic EPS, which excludes dilution and is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for the period. The Statement also requires the dual presentation of basic and diluted EPS on the face of the income statement for all companies with complex capital structures and requires a reconciliation of the numerator and denominator of the basic EPS computation to the numerator and denominator of the diluted EPS computation. Diluted EPS is computed similarly to fully diluted EPS pursuant to APB Opinion No. 15. EPS has been retroactively restated to reflect the requirements of SFAS No. 128. In June 1997, the FASB issued SFAS No. 130, REPORTING COMPREHENSIVE INCOME. The Statement is effective for fiscal years beginning after December 15, 1997. The Statement establishes standards for reporting and display of comprehensive income and its components (revenues, expenses, gains and losses) in a full set of general-purpose financial statements. The Statement requires that all items that are required to be recognized under accounting standards as components of comprehensive income be reported in a financial statement that is displayed with the same prominence as other financial statements. We will adopt this Statement in fiscal year 1999. In June 1997, the FASB issued SFAS No. 131, DISCLOSURES ABOUT SEGMENTS OF AN ENTERPRISE AND RELATED INFORMATION. The Statement is effective for fiscal years beginning after December 15, 1997. The Statement establishes standards for the way that public business enterprises report information about operating segments as well as related disclosures about products and services, geographic areas, and major clients. The Statement also requires that a public business report descriptive information about the way that the operating segments were determined, the products and services provided by the operating segments, differences between the measurements used in reporting segment information and those used in the enterprise's general-purpose financial statements, and changes in the measurement of segment amounts from period to period. The Statement need not be applied to interim financial statements in the initial year of its application. We have not completed our analysis of the effect of SFAS No. 131 on our financial statements. We will adopt this Statement in fiscal year 1999. In June 1998, the FASB issued SFAS No. 133, ACCOUNTING FOR DERIVATIVES AND HEDGING ACTIVITIES. The Statement is effective for all fiscal quarters of fiscal years beginning after June 15, 1999. The Statement requires companies to recognize all derivative instruments on their balance sheet as either assets or liabilities measured at fair value. The Statement also specifies a new method of accounting for hedging transactions, prescribes the type of items and transactions that may be hedged, and specifies detailed criteria to be met to qualify for hedge accounting. We will adopt this Statement in fiscal year 2001. MARKET RISKS We currently utilize no 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 December 15, 2000 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 debt based on anticipated payments within and beyond one year's period of time. We presently anticipate repaying our long-term debt in the amounts of $14,065,000, $15,546,000 and $18,000,000 in fiscal 1999, 2000 and 2001, respectively. Assuming we pay our long-term debt in such amounts ratably throughout the year, and our average interest rate on our long-term debt increases or decreases by one percentage point, our interest expense would increase or decrease by $406,000, $258,000 and $90,000 in fiscal 1999, 2000 and 2001, respectively. However, there can be no assurance that the Company will, or will be able to, repay its long-term debt in the manner described. For example, we could incur additional debt under this credit facility or our operating results could be worse than we expect. YEAR 2000 We are working to resolve the potential impact of the year 2000 on our business operations and the ability of our computerized information systems to accurately process information that may be date-sensitive. Any of our programs that recognize a date using "00" as the year 1900 rather than the year 2000 could result in errors or system failures. We utilize a number of computer programs across our entire operation. The primary information technology (IT) systems we utilize are (1) the accounting and financial systems which include general ledger, accounts payable, accounts receivable, billing and collection, fixed assets, job cost accounting and payroll, and (2) human resource information management systems. We do not believe we have a material amount of non-IT systems on which we rely. We have established both a year 2000 review committee and a year 2000 action team. The purpose of the review committee is to develop and communicate our year 2000 plan to achieve our year 2000 compliance mission. The purpose of the action team is to identify, remediate and implement plans to resolve our year 2000 related issues. Through the review committee and the action team, we are in the process of completing our full assessment of all issues relating to the year 2000. We have developed questionnaires regarding year 2000 readiness to be used internally and externally. We have completed our internal assessment and we are in the process of assessing the year 2000 issues of our clients and vendors. Based on the information collected to date, we do not believe that the cost of addressing our year 2000 issues will have a material adverse impact on our financial position. We plan to devote all resources required to resolve any significant year 2000 issues in a timely manner. STATE OF READINESS We began our risk assessment in 1995. Since that time we have procured and implemented certain accounting and financial reporting systems as well as contract administration and billing systems that have been certified as year 2000 compliant by our vendors. Currently, approximately 72% of our gross revenue is recognized on these year 2000 compliant systems. We have successfully converted 7 of our 18 operating units to these year 2000 compliant systems. We are planning to convert four additional operating units by July 1999. The operating units that will not be converted to the systems currently in place are in the process of upgrading their existing systems to a year 2000 compliant version or will procure and implement a year 2000 compliant software. In all cases, we believe that our financial and accounting systems will be year 2000 compliant in a timely manner and will not be materially impacted by the year 2000. We are currently installing a year 2000 compliant human resource information management system. Ten operating units including our corporate units will be supported by this system. The anticipated completion date is April 1999. We plan to convert the remaining operating units following April 1999. In all cases, we believe that our human resource management information systems will be year 2000 compliant in a timely manner and will not be materially impacted by the year 2000. We have expended or obligated approximately $2.6 million on the procurement of these systems, the conversion of data from legacy systems to these systems, and on the implementation and testing of these systems. We have extensive business with the Federal government. Should the Federal government, specifically the Department of Defense, experience significant business interruptions relating to non-year 2000 compliance, we could be materially impacted. To the extent that other third parties upon which we rely, such as banking institutions, clients and vendors, are unable to address their year 2000 issues in a timely manner, we could be materially impacted. We believe that the worst case scenario relating to the year 2000 would be an extensive period of time in which the Federal government and other third parties could not process payments promptly. RISKS We believe the risks associated with non-year 2000 compliance include: (1) our inability to invoice and process payments, (2) our inability to produce accurate and timely financials, (3) the impact on our cash flow and working capital needs, (4) the impact on our profitability, and (5) our liability to third parties for not meeting contracted deliverables. CONTINGENCY PLANS We currently do not have formal contingency plans for the failure of our financial and accounting systems. We have substantial experience in the conversion process from multiple legacy systems to our current year 2000 certified systems. We have an experienced and dedicated staff to perform the functions identified and are reasonably confident that the projected conversions will be accomplished as projected. We currently do not have formal contingency plans for the failure of our human resource information management system. Our implementation strategy is to install the system as simply as possible, with little customization. Our vendor supports our implementation strategy and has agreed to a financial penalty if the implementation is not achieved within three months, or by April 1999. If the implementation is not achieved by April 1999, we believe there will still be sufficient time to meet the year 2000 deadline. We maintain, as a matter of policy and practice, mitigation plans in the event of systems failure which includes regular backup of historical information. INDEPENDENT AUDITORS' REPORT Tetra Tech, Inc.: We have audited the accompanying consolidated balance sheets of Tetra Tech, Inc. and its subsidiaries as of October 4, 1998 and September 28, 1997, and the related consolidated statements of income, stockholders' equity, and cash flows for each of the three years in the period ended October 4, 1998. 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 generally accepted auditing standards. 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 4, 1998 and September 28, 1997, and the results of their operations and their cash flows for each of the three years in the period ended October 4, 1998 in conformity with generally accepted accounting principles.

TETRA TECH, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS FISCAL YEARS ENDED OCTOBER 4, 1998, SEPTEMBER 28, 1997 AND SEPTEMBER 29, 1996 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 and its wholly-owned subsidiaries. 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 year 1998 contained 53 weeks. Fiscal years 1997 and 1996 contained 52 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 revenues 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 are 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. Contract revenue under Federal government contracts and subcontracts accounted for approximately 48.7%, 52.3% and 61.7%, of net contract revenue for the years ended October 4, 1998, September 28, 1997 and September 29, 1996, 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. LONG-LIVED ASSETS - The Company reviews the recoverability of long-lived assets to determine if there has been any impairment. 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. Long-lived assets as of October 4, 1998 and September 28, 1997 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 4, 1998 and September 28, 1997 was $6,490,000 and $3,522,000, 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 - Due to the Company's complex capital structure, the Company presents both basic and diluted Earnings Per Share (EPS). Basic 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 net income 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 share for share for the Company's common stock. The redeemable preferred stock has 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. Basic and diluted EPS reflect, on a retroactive basis, a 5-for-4 stock split effected in the form of a 25% stock dividend, wherein one additional share of stock was issued on September 15, 1998 for each four shares outstanding as of the record date of July 27, 1998. FAIR VALUE OF FINANCIAL INSTRUMENTS - CASH AND CASH EQUIVALENTS, ACCOUNTS RECEIVABLE, UNBILLED RECEIVABLES AND ACCOUNTS PAYABLE- The carrying amounts approximate fair value because of the short maturities of these instruments. REVOLVING CREDIT FACILITY - The carrying amount 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 temporary cash investments and accounts receivable. 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 4, 1998, approximately 44% 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 customer 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 generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. ACCOUNTING PRONOUNCEMENTS - In February 1997, the Financial Acounting Standards Board (FASB) issued Statement of Financial Accounting Standard (SFAS) No. 128, EARNINGS PER SHARE, which the Company adopted in fiscal year 1998. The Statement replaces the presentation of primary EPS with a presentation of basic EPS, which excludes dilution and is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for the period. The Statement also requires the dual presentation of basic and diluted EPS on the face of the income statement for all companies with complex capital structures and requires a reconciliation of the numerator and denominator of the basic EPS computation to the numerator and denominator of the diluted EPS computation. Diluted EPS is computed similarly to fully diluted EPS pursuant to APB Opinion No. 15. EPS has been retroactively restated to reflect the requirements of SFAS No. 128. In June 1997, the FASB issued SFAS No. 130, REPORTING COMPREHENSIVE INCOME. The Statement is effective for fiscal years beginning after December 15, 1997. The Statement establishes standards for reporting and display of comprehensive income and its components (revenues, expenses, gains and losses) in a full set of general-purpose financial statements. This Statement requires that all items that are required to be recognized under accounting standards as components of comprehensive income be reported in a financial statement that is displayed with the same prominence as other financial statements. The Company will adopt this Statement in fiscal year 1999. In June 1997, the FASB issued SFAS No. 131, DISCLOSURES ABOUT SEGMENTS OF AN ENTERPRISE AND RELATED Information. The Statement is effective for fiscal years beginning after December 15, 1997. The Statement establishes standards for the way that public business enterprises report information about operating segments as well as related disclosures about products and services, geographic areas, and major clients. The Statement also requires that a public business report descriptive information about the way that the operating segments were determined, the products and services provided by the operating segments, differences between the measurements used in reporting segment information and those used in the enterprise's general-purpose financial statements, and changes in the measurement of segment amounts from period to period. The Statement need not be applied to interim financial statements in the initial year of its application. The Company has not yet completed its analysis of the effect of SFAS No. 131 on its financial statements. The Company will adopt this Statement in fiscal year 1999. In June 1998, the FASB issued SFAS No. 133, ACCOUNTING FOR DERIVATIVES AND HEDGING ACTIVITIES. The Statement is effective for all fiscal quarters of all fiscal years beginning after June 15, 1999. The Statement requires companies to recognize all derivative instruments on their balance sheet as either assets or liabilities measured at fair value. The Statement also specifies a new method of accounting for hedging transactions, prescribes the type of items and transactions that may be hedged, and specifies detailed criteria to be met to qualify for hedge accounting. The Company does not anticipate that the adoption of SFAS No. 133 will have a material effect on the Company's financial statements. The Company will adopt this Statement in fiscal year 2001. 2.

NUS provides consulting, engineering and design services for the environmental remediation of contaminated air, water and soil conditions. The purchase price has been valued at approximately $25,217,000, as adjusted, and consisted of cash. On July 11, 1997, the Company acquired 100% of the capital stock of CommSite Development Corporation (CDC), a wireless telecommunications site development service firm. The purchase has been valued at approximately $5,702,000 consisting of cash and 397,598 shares of Company common stock, as adjusted based on CDC's Net Asset Value on July 11, 1997 as described in the related purchase agreement. On June 11, 1997, the Company acquired 100% of the capital stock of Whalen & Company, Inc. and Whalen Service Corps Inc. (collectively, WAC). WAC, a wireless telecommunications firm, provides a full range of wireless telecommunications site development services for PCS, cellular, ESMR, air-to-ground, microwave, paging, fiber optic and switching centers technology. The purchase has been valued at approximately $41,738,000 consisting of cash and 4,549,750 shares of Company common stock. Initially, the Company issued 1,231,840 shares of redeemable preferred stock. The shares of redeemable preferred stock were subsequently converted into common stock prior to the stock split which occurred on December 1, 1997. The common and preferred stock were issued in a private placement and had a combined value of $31,972,000. On the business day prior to the merger, WAC distributed to its stockholders (i) cash in the amount of $4,138,000 and (ii) accounts receivable having a net value of $18,456,000. On March 20, 1997, the Company acquired 100% of the capital stock of SCM Consultants, Inc. (SCM), a consulting and engineering firm providing design of irrigation, water and wastewater systems, as well as facility and infrastructure engineering services, to state and local government, private and industrial clients.

On November 7, 1995, the Company acquired 100% of the capital stock of KCM, Inc. (KCM), an engineering services firm specializing in areas of water quality, water and wastewater systems, surface water management, fisheries and facilities. The purchase was valued at approximately $13,373,000, consisting of cash and 1,234,744 shares of Company common stock issued in a private placement. 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 market 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 balance sheets. The Company values stock exchanged in acquisitions based on extended restriction periods and economic factors specific to the Company's circumstances. During fiscal 1998, stock exchanged in acquisitions was discounted by 15%. During fiscal 1997, the discount on stock exchanged in acquisitions ranged from 16% to 28%. During fiscal 1996, stock exchanged in the acquisition was discounted by 26%. The results of operations of each of the companies acquired have been included in the Company's financial statements from their respective acquisition effective dates as set forth in the related purchase agreements. The effect of unaudited pro forma operating results of the SGOC, CDE, SCM, FLO and IWA acquisitions, had they been acquired on September 30, 1996, is not material. The following table presents summarized unaudited pro forma operating results assuming that the Company had acquired MPS, NUS, CDC and WAC on September 30, 1996: Fiscal Year Ended ----------------------------------------------------------- Oct. 4, 1998 Sept. 28, 1997 ----------------------------------------------------------- Gross revenue $ 429,591,000 $ 420,294,000 Income before income tax expense 37,958,000 33,637,000 Net income 21,446,000 19,510,000 Basic earnings per share $ 0.76 $ 0.72 Diluted earnings per share 0.73 0.69 Weighted average shares common outstanding: Basic 28,176,000 26,977,000 Diluted 29,397,000 28,262,000 3. ACCOUNTS RECEIVABLE Accounts receivable consisted of the following at October 4, 1998 and September 28, 1997: Oct. 4, 1998 Sept. 28, 1997 --------------- --------------- Billed accounts receivable............................... $ 71,745,000 $ 31,435,000 --------------- --------------- Unbilled accounts receivable: Billable amounts not invoiced, amounts billable at stipulated stages of completion of contract work, and unbilled amounts pending negotiation or receipt of contract modifications................ 58,384,000 31,626,000 Costs and fee retention billable upon audit of total contract costs .................................. 11,278,000 13,326,000 --------------- --------------- Total unbilled accounts receivable ...................... 69,662,000 44,952,000 --------------- --------------- Allowance for uncollectible accounts: Allowance for doubtful accounts..................... (2,911,000) (1,346,000) Allowance for disallowed costs ..................... (9,774,000) (9,807,000) --------------- --------------- Total allowance for uncollectible accounts.............. (12,685,000) (11,153,000) --------------- --------------- Total ................................................... $ 128,722,000 $ 65,234,000 --------------- --------------- --------------- --------------- 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, however, 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). EMI likewise contracts with the Federal government. At the time of acquisition, audits had not been performed for years beyond 1986. As of September 1998, audits and negotiations relating to the EMI contracts for years 1987 through 1995 had been completed, and cost disallowances as a result of audits totaled approximately $2,900,000. It has been determined by the Federal government that for these periods the Company is entitled to payments, however, the collectibility of such payments cannot be assured as each agency must obtain separate funding approval. 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 potential loss has been 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 4, 1998, the Company has approximately $5,200,000 under retainage provisions of contracts and approximately $2,166,000 of accounts receivable which may not be realized within one year. 4. INCOME TAXES Income tax expense for the years ended October 4, 1998, September 28, 1997 and September 29, 1996 consisted of the following: Fiscal Year Ended ------------------------------------------------------- Oct. 4, Sept. 28, Sept. 29, 1998 1997 1996 ------------- ------------- ------------- Current: Federal............................ $ 15,284,000 $ 9,220,000 $ 5,849,000 State.............................. 3,535,000 2,291,000 1,462,000 Deferred .............................

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. At October 4, 1998, the Credit Agreement provided a revolving credit facility of $70,000,000. The Credit Agreement provides for mandatory reductions of $5,000,000 on December 15, 1998 and December 15, 1999. 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 at October 4, 1998 was 6.34375%. Borrowings under the Credit Agreement are secured by the Company's accounts receivable and the stock of five 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). The Credit Agreement matures on December 15, 2000 or earlier at the discretion of the Company upon payment in full of loans and other obligations. As of October 4, 1998, outstanding borrowings totaled $47,000,000 and standby letters of credit totaled $2,207,000. 6. EXCHANGEABLE STOCK OF A SUBSIDIARY In connection with the SGOC acquisition, the Company issued 920,354 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 whereas a holder of Exchangeable Shares shall be 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 causing to be delivered to such holder one share of the Company's common stock for each Exchangeable Share presented and surrendered, plus (b) a dividend amount, if any. The Exchangeable Shares cannot be put back to the Company for cash. 7. STOCKHOLDERS' EQUITY On September 14, 1998, a Special Meeting of the Stockholders (the "Special Meeting") was held. During the Special Meeting, the stockholders approved a proposal to amend the Company's Certificate of Incorporation to increase the number of authorized shares of common stock, $.01 par value per share, from 30,000,000 to 50,000,000. On September 15, 1998, the Company paid a five-for-four split of the Company's common stock, effected in the form of a 25% stock dividend, payable on September 15, 1998 to the stockholders of record on July 27, 1998. All agreements concerning stock options and other commitments payable in shares of the Company's common stock are affected by the five-for-four split. All references to number of shares (except shares authorized), stock options, share prices and per share information in the consolidated financial statements have been adjusted to reflect the stock split on a retroactive basis. Pursuant to the Company's 1989 Stock Option Plan, key employees may be granted options to purchase an aggregate of 953,672 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 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 4,609,375 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 Non-employee Director Plan, non-employee directors may be granted options to purchase an aggregate of 114,438 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 878,906 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 4, 1998, option activity was as follows: Number Weighted Average of Options Exercise Price -------------- ----------------- Balance, October 1, 1995........................ 1,565,270 $ 5.82 Granted.................................... 644,667 11.36 Exercised..................................

Accordingly, no compensation expense has been recognized for its stock-based compensation plans. Pro forma net income and net income per share had the Company accounted for stock options issued to employees in accordance with SFAS No. 123, ACCOUNTING FOR STOCK-BASED COMPENSATION, are as follows: Fiscal Year Ended -------------------------------------------------------------- Oct. 4, 1998 Sept. 28, 1997 Sept. 29, 1996 ------------------- ------------------- ------------------ Net income-as reported.............................. $ 20,586,000 $ 14,256,000 $ 10,105,000 Net income-pro forma................................ 18,980,000 13,059,000 9,598,000 Basic earnings per share-as reported................ $ 0.74 $ 0.61 $ 0.46 Diluted earnings per share-as reported.............. 0.71 0.58 0.45 Basic earnings per share-pro forma.................. 0.68 0.56 0.44 Diluted earnings per share-pro forma................ 0.65 0.53 0.43 The pro forma effects of applying SFAS No. 123 may not be representative of the effects on reported net income and net income per share for future years since options vest over several years and additional awards are made each year.
