WHALEN & COMPANY, INC. NOTES TO FINANCIAL STATEMENTS YEARS ENDED DECEMBER 31, 1996, 1995 AND 1994 1. SIGNIFICANT ACCOUNTING POLICIES DESCRIPTION OF BUSINESS - Whalen & Company, Inc.

The Company has consulting experience in PCS, cellular, ESMR, wireless, air-to-ground, microwave, paging, fiber optic and switching center systems. The Company provides services in North America, South America, Asia, Australia and Europe. FINANCIAL STATEMENT 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. Significant estimates include a provision for doubtful accounts. Actual results could differ from estimates. CASH AND EQUIVALENTS - Cash and equivalents include cash and highly liquid debt instruments with original maturities of three months or less. ACCOUNTS RECEIVABLE - Accounts receivable includes billed and unbilled accounts receivable. Total unbilled accounts receivable were $6,794,000 and $3,061,000 as of December 31, 1996 and 1995, respectively. CONCENTRATION OF CREDIT RISK - Financial instruments which potentially subject the Company to concentrations of credit risk consist primarily of cash and equivalents and accounts receivable. The Company places its cash and equivalents for safekeeping with high-credit-quality financial institutions. The Company performs ongoing credit evaluations of its customers and generally requires that customers remit payment for billed revenue within 30 days. The Company maintains reserves for estimated credit losses. See Note 7 concerning significant customers. PROPERTY AND EQUIPMENT - Property and equipment are stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets ranging from two to seven years. REVENUE RECOGNITION - The Company recognizes management fee revenue as project management and consulting services are performed in accordance with customer contracts. The recognition of revenue related to per-site fees is deferred until milestones in the Company's customer contracts have been met and collection is reasonably assured. Per-site fees in 1996 include $8,407,000 from a single customer of which $2,511,000 were related to 1995 and had been deferred as of December 31, 1995 due to the uncertainty of collection as of that date. REIMBURSABLE EXPENSES - Certain expenses incurred by the Company are passed on to customers in accordance with customer contract agreements. The Company records the expense and reimbursement on a gross basis. The amounts included in management fees and field operating expenses were $6,861,000, $7,122,000 and $6,128,000 in 1996, 1995 and 1994, respectively.

INCOME TAXES - The Company's stockholder elected to be taxed as an S corporation under the provisions of the Internal Revenue Code. Under these provisions, the Company does not pay federal corporate income taxes on its taxable income.

TETRA TECH, INC. AND WHALEN & COMPANY, INC. NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (In thousands) 1. PERIODS PRESENTED On June 11, 1997, Tetra Tech, Inc. ("Tetra Tech") purchased 100% of the capital stock of Whalen & Company, Inc. and Whalen Service Corps Inc. (collectively, "WAC") for approximately $43,070 consisting of cash and Tetra Tech common and preferred stock. The common and preferred stock was issued in a private placement and had a combined value of approximately $33,304. Tetra Tech's stock was valued based upon the extended restriction period and economic factors specific to Tetra Tech's circumstances which resulted in a fair valuation approximately 28% below the then prevailing market price. The Unaudited Pro Forma Condensed Consolidated Statements of Operations have been prepared by combining the separate historical financial statements of Tetra Tech and WAC for the year ended September 29, 1996 and the nine months ended June 29, 1997. The historical statements of operations for WAC included in the Unaudited Pro Forma Condensed Consolidated Statement of Operations for the year ended September 29, 1996 represent the results of operations for the year ended December 31, 1996. The historical statement of operations for WAC included in the Unaudited Pro Forma Condensed Consolidated Statement of Operations for the nine months ended June 29, 1997 represents the results of operations for the period October 1, 1996 through May 31, 1997. The Statement of Operations for the period June 1, 1997 through June 29, 1997 for WAC is reflected in the historical Condensed Consolidated Statement of Operations of Tetra Tech for the period ended June 29, 1997. An Unaudited Pro Forma Condensed Consolidated Balance Sheet has not been prepared as WAC is included in the Unaudited Condensed Consolidated Balance Sheet at June 29, 1997 for Tetra Tech, Inc. as filed in Tetra Tech's Quarterly Report on Form 10-Q for the period ended June 29, 1997. 2. PRO FORMA ADJUSTMENTS RELATED TO THE ACQUISITION The adjustments to Cost of Net Revenue of $1,726 and $3,542 and the adjustments to Selling, General and Administrative Expenses of $547 and $1,947 for the year ended September 29, 1996 and the nine months ended June 29, 1997, respectively, represent salary and bonus expense adjustments for WAC employees and WAC's principal stockholder. Prior to the acquisition, WAC was an S corporation and made distributions to its principal stockholder in lieu of increased salary and bonus. Immediately prior to the acquisition, WAC declared a one-time bonus of approximately $5,000 for certain employees as a result of terms negotiated in the acquisition. The pro forma adjustments reflect the net effect of the bonus that would have been recognized under Tetra Tech's established bonus policy, net of the bonuses declared by WAC, and the terms of the Employment Agreement between Tetra Tech and the principal stockholder for each of the periods provided. The adjustments to Selling, General and Administrative Expenses of $1,317 and $987 for the year ended September 29, 1996 and the nine months ended June 29, 1997, respectively, represent the amortization of intangible assets resulting from the acquisition. The intangible assets are amortized on a straight-line basis over thirty years. The adjustments to Interest Expense of $700 and $263 for the year ended September 29, 1996 and the nine months ended June 29, 1997, respectively, represent expense on borrowings under Tetra Tech, Inc.'s existing credit facility that relate to the acquisition of WAC. Such adjustments are based upon the average interest rates and terms of the credit facility for the periods presented. The adjustments to Income Tax Expense of $4,239 and $1,992 for the year ended September 29, 1996 and the nine months ended June 29, 1997, respectively, represent the income tax effect of the pro forma adjustments (since WAC was, as indicated above, an S corporation taxpayer) and an adjustment to reflect the consolidated effective income tax rate. 3. EARNINGS PER SHARE The adjustments to Shares Used in Per Share Calculations of 2,912 shares and 2,866 shares for the year ended September 29, 1996 and the nine months ended June 29, 1997, respectively, represent the number of additional shares that would have been outstanding had the shares issued in the acquisition been outstanding for the entire periods reflected. The unaudited pro forma consolidated Net Income Per Common Share was computed by dividing the pro forma consolidated Net Income by the pro forma weighted average number of common shares and common stock equivalents outstanding for each period.
