Notes To Condensed Consolidated Financial Statements

1. Basis of Presentation

The accompanying condensed consolidated balance sheet as of April 2, 2006, the condensed consolidated statements of operations for the three and six months ended April 2, 2006 and April 3, 2005, and the condensed consolidated statements of cash flows for the six months ended April 2, 2006 and April 3, 2005 of Tetra Tech, Inc. (the “Company”) are unaudited, and, in the opinion of management, include all adjustments necessary for a fair statement of the financial position and the results of operations for the periods presented.

The condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended October 2, 2005. Certain prior year amounts have been reclassified to conform to the current year presentation due to discontinued operations. The results of operations for the three and six months ended April 2, 2006 are not necessarily indicative of the results to be expected for the fiscal year ending October 1, 2006.

2. Discontinued Operations

The results for eXpert Wireless Solutions, Inc. (EWS), Vertex Engineering Services, Inc. (VES), Tetra Tech Canada Ltd. (TTC) and Whalen & Company, Inc. (WAC) were accounted for as discontinued operations in the condensed consolidated financial statements for all periods presented herein. On October 1, 2005, the Company completed the sale of EWS, an operating unit in the communications segment. The VES and TTC operations were considered to be held for sale in fiscal 2005, and thus were classified as discontinued operations in the fourth quarter of fiscal 2005. The Company ceased all revenue producing activities for WAC, an operating unit in the communications segment, and its operations were considered abandoned in the first quarter of fiscal 2006. As such, WAC was also accounted for as a discontinued operation in the financial statements beginning in that quarter.

In the first quarter of fiscal 2006, the Company entered into a stock purchase agreement to sell VES, an operating unit in the resource management segment. The Company completed negotiations regarding the final terms of the sale in March 2006. To date, the Company has received a net amount of $0.2 million in cash and $11.7 million in a promissory note that bears interest at 5% to 7% per annum over the payment term and matures on November 1, 2009. The promissory note receivable was included in current and non-current assets of discontinued operations on the condensed consolidated balance sheet as of April 2, 2006. Due to the minimal amount of net cash received, the Company determined that no sale occurred for accounting purposes. Therefore, the Company did not recognize any gain on the sale of VES during the six months ended April 2, 2006. The Company expects to recognize modest gains upon receipt of additional cash from VES.

In the first quarter of fiscal 2006, the Company sold TTC, an operating unit in the communications segment, for approximately $4.9 million. The Company received a payment in February 2006 in the amount of $1.0 million. The purchase price is payable pursuant to a promissory note that bears interest at 5% to 7% per annum over the payment term and matures on December 1, 2007. This note receivable was included in prepaid expenses and other current assets and in other assets on the condensed consolidated balance sheet as of April 2, 2006. In connection with the sale and upon receipt of a substantial downpayment, the Company recognized a net gain of $1.1 million, net of tax, in the quarter ended April 2, 2006.

The summarized, combined statements of operations for discontinued operations were as follows:

	Three Months Ended						Six Months Ended
	April 2, 2006			April 3, 2005			April 2, 2006			April 3, 2005
	(in thousands)

Revenue	$	64		$	(4,705	)	$	9,697		$	33,972

Loss before income tax benefit	(433		)	(40,410		)	(1,646		)	(38,648		)
Income tax benefit	(175		)	(14,521		)	(656		)	(13,802		)
Loss from operations, net of tax	(258		)	(25,889		)	(990		)	(24,846		)

Gain on sale of discontinued operations, net of tax	1,117			—			1,384			—

Income (loss) from discontinued operations, net of tax	$	859		$	(25,889	)	$	394		$	(24,846	)

In connection with the Company’s decision to exit the wireless communications business in the second quarter of fiscal 2005, the Company recorded a $23.5 million reduction in revenue, which more than offset the revenue generated by the other discontinued operations. As a result, revenue from discontinued operations for the second quarter of fiscal 2005 was negative.

The current assets of discontinued operations included net accounts receivable of $1.0 million and $23.8 million as of April 2, 2006 and October 2, 2005, respectively.

3. Goodwill and Intangibles

The changes in the carrying value of goodwill by segment for the six months ended April 2, 2006 were as follows:

	October 2, 2005		Goodwill Addition		April 2, 2006
	(in thousands)

Resource management	$	86,011	$	—	$	86,011
Infrastructure	73,164		905		74,069
Total	$	159,175	$	905	$	160,080

The goodwill addition of $0.9 million resulted from the January 2006 acquisition of assets of two engineering companies in the infrastructure segment for a combined purchase price of $1.8 million, which consisted of cash and notes payable. The acquisitions were accounted for as purchases. Accordingly, the purchase prices of the assets acquired were allocated to the assets and liabilities acquired based on their fair values. The excess of the purchase cost of the acquisitions over the fair value of the net tangible and identifiable intangible assets acquired was recorded as goodwill, and was included in goodwill on the condensed consolidated balance sheet as of April 2, 2006. These acquisitions were not considered material and the acquired businesses did not have a material impact on the Company’s financial position, results of operations or cash flows for the three and six months ended April 2, 2006.

The gross amounts and accumulated amortization of the Company’s acquired identifiable intangible assets with finite useful lives as of April 2, 2006 and October 2, 2005, included in intangible assets-net in the condensed consolidated balance sheets, were as follows:

	April 2, 2006					October 2, 2005
	Gross Amount		Accumulated Amortization			Gross Amount		Accumulated Amortization
	(in thousands)

Backlog	$	9,075	$	(3,890	)	$	8,900	$	(3,232	)

Identifiable intangible assets in the amount of $0.2 million were acquired during the six months ended April 2, 2006. Amortization expense for acquired identifiable intangible assets with finite useful lives was $0.7 million and $1.1 million for the six months ended April 2, 2006 and April 3, 2005, respectively. Estimated amortization expense for the remainder of fiscal 2006 and the succeeding five years is as follows:

(in thousands)
2006	$	679
2007	1,359
2008	1,293
2009	1,271
2010	583

4. Stock-Based Compensation

As of April 2, 2006 the Company had the following share-based compensation plans:

• 1989 Stock Option Plan – Key employees were granted options to purchase an aggregate of 1,490,112 shares of the Company’s common stock at prices ranging from 100% to 110% of market value on the date of grant. The 1989 Stock Option Plan terminated in 1999, except as to outstanding options. All options granted by the Company were at least 100% of market value at the date of grant. Those options vested at 25% per year and became exercisable beginning one year from the date of grant, became fully vested in four years, and terminate no later than ten years from the date of grant.

• 1992 Incentive Stock Plan – Key employees were granted options to purchase an aggregate of 7,202,147 shares of the Company’s common stock at prices not less than 100% of market value on the date of grant. The 1992 Incentive Stock Plan terminated in December 2002, except as to the outstanding options. All options granted were at market value at the date of grant. These options became exercisable one year from the date of grant, became fully vested no later than five years, and terminate no later than ten years from the date of grant.

• 1992 Stock Option Plan for Non-employee Directors – Non-employee directors were granted options to purchase an aggregate of 178,808 shares of the Company’s common stock at prices not less than 100% of market value on the date of grant. This plan terminated in December 2002, except as to the outstanding options. All options granted were at market value on the date of grant. These options are fully vested and terminate no later than ten years from the date of grant.

• 2003 Outside Director Stock Option Plan – Non-employee directors may be granted options to purchase an aggregate of up to 400,000 shares of the Company’s common stock at prices not less than 100% of the market value on the date of grant. All options granted were at the market value on the date of grant. These options vest and become exercisable on the first anniversary of the date of grant if the director has not ceased to be a director prior to such date, and terminate no later than ten years from the grant date.

• 2005 Equity Incentive Plan – Key employees may be granted options to purchase an aggregate of 3,580,702 shares of the Company’s common stock at prices not less than 100% of market value on the date of grant. This plan amended, restated and renamed the 2002 Stock Option Plan. All options granted were at market value on the date of grant. Options granted before March 6, 2006 vest at 25% on the first anniversary of the grant date, and the balance vests monthly thereafter, such that these options become fully vested no later than four years from the date of grant. These options terminate no later than ten years from the date of grant. Options granted on and after March 6, 2006 vest at 25% on each anniversary of the grant date. These options terminate no later than eight years from the grant date.

• Employee Stock Purchase Plan (Purchase Plan) – Purchase right to purchase common stock are granted to eligible full and part-time employees of the Company, and shares of common stock are issued upon exercise of the purchase rights. An aggregate of 2,373,290 shares may be issued pursuant to such exercise. The maximum amount that an employee can contribute during a

purchase right period is $5,000, and the minimum contribution per payroll period is $25. The exercise price of a purchase right is the lesser of 100% of the fair market value of a share of common stock 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.

Prior to October 3, 2005, the Company applied Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees, and related interpretations in accounting for these plans. No stock-based compensation expense was recognized in the Company’s results of operations prior to fiscal 2006, as the exercise price was equal to the market price of the Company’s stock on the date of grant. In addition, the Company did not recognize any stock-based compensation expense for the Purchase Plan as it was intended to qualify under Section 423 of the Internal Revenue Code of 1986, as amended.

In the fourth quarter of fiscal 2005, the Company’s Board of Directors approved accelerating the vesting of certain outstanding, unvested stock options awarded to employees under the Company’s stock option plans, other than its 2003 Outside Director Stock Option Plan, with exercise prices greater than $16.95, the closing price of the Company’s common stock on September 6, 2005. As a result of this vesting acceleration, options to purchase approximately 1.6 million shares of the Company’s common stock became fully vested and immediately exercisable. As the exercise price of all modified options was greater than the market price of the Company’s underlying common stock on the date of their modification, no compensation expense was recorded in accordance with APB 25. The decision to accelerate vesting of these options was made primarily to eliminate the accounting charge in connection with future compensation expense the Company would otherwise recognize in its statements of operations with respect to these accelerated options upon the adoption of Statement of Financial Accounting Standards (SFAS) No. 123 (revised 2004), Share-Based Payment (SFAS 123R).

Effective October 3, 2005, the Company adopted the fair value recognition provisions of SFAS 123R, requiring the Company to recognize expense related to the fair value of its stock-based compensation awards. The Company elected the modified prospective transition method as permitted by SFAS 123R. Under this transition method, stock-based compensation expense for the six months ended April 2, 2006 included: (a) compensation expense for all stock-based compensation awards granted prior to, but not yet vested as of, October 3, 2005, based on the grant date fair value estimated in accordance with the original provisions of SFAS No. 123, Accounting for Stock-Based Compensation (SFAS 123), and (b) compensation expense for all stock-based compensation awards granted subsequent to October 2, 2005, based on the grant date fair value estimated in accordance with SFAS 123R. Further, in accordance with the modified prospective transition method, financial results for prior periods were not adjusted.

As a result of adopting SFAS 123R on October 3, 2005, the Company’s income from continuing operations before income tax expense for the three and six months ended April 2, 2006 included $1.2 million and $2.2 million charges for stock-based compensation expense, respectively. These charges reduced both basic and diluted earnings per share from continuing operations by $0.02 and $0.04 for the three and six months ended April 2, 2006, respectively.

There was no tax benefit associated with the compensation costs resulting from the adoption of SFAS 123R for the current period because incentive stock options were granted. The Company may receive future tax benefits when these options are exercised. The options granted in March 2006 are non-qualified stock options, and an associated tax benefit of $0.1 million was reflected in net income for the three and six months ended April 2, 2006.

Prior to the adoption of SFAS 123R, the Company reported all tax benefits resulting from the exercise of stock options as operating cash flows in its statements of cash flows. In accordance with SFAS 123R, the Company will present excess tax benefits from the exercise of stock options as financing cash flows. For the three and six months ended April 2, 2006, no excess tax benefits were recognized.

The table below illustrates the effect on net loss and loss per share as if the Company had applied the fair value recognition provisions of SFAS 123 to stock-based compensation for the three and six months ended April 3, 2005:

	Three Months Ended			Six Months Ended

Exercisable on April 2, 2006	3,636		$	17.21	5.8	$	12,393

Included in the options granted during the period ended April 2, 2006 is an award of 20,000 shares of restricted stock, which has a grant date fair value of $0.3 million and vests over a three-year period.

For the three and six months ended April 2, 2006, no shares were issued under the Purchase Plan.

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between the Company’s closing stock price on the last trading day of the first and second quarters of fiscal 2006, respectively, and the exercise price, times the number of shares) that would have been received by the option holders if they had exercised their options on January 1, 2006 and April 2, 2006. This amount will change based on the fair market value of the Company’s stock. As of April 2, 2006, approximately $13.3 million of total unrecognized stock-based compensation cost was expected to be recognized over a weighted-average period of 2.9 years.

The weighted-average fair value of stock options granted during the three months ended April 2, 2006 and April 3, 2005 was $8.29 and $7.79, respectively. The weighted-average fair value of stock options granted during the six months ended April 2, 2006 and April 3, 2005 was $8.23 and $7.97, respectively. The aggregate intrinsic value of options (the amount by which the market price of the stock on a specific valuation date exceeded the market price of the stock on the date of grant) exercised during the three months ended April 2, 2006 and April 3, 2005 was

$1.4 million and $0.9 million, respectively, and during the six months ended April 2, 2006 and April 3, 2005 was $2.0 million and $2.2 million, respectively.

The fair value of the Company’s stock options was estimated on the date of grant using the Black-Scholes option pricing model. The following assumptions were used in completing the model:

	Six Months Ended
Black-Scholes Options Valuations Assumptions	April 2, 2006	April 3, 2005
Dividend yield	0.0%	0.0%
Expected stock price volatility	42.8%	55.9%
Risk-free rate of return, annual	3.7% - 4.8%	3.7% - 4.2%
Expected life (in years)	4.5 - 6.1	4.7

For purposes of the Black-Scholes model, forfeitures were estimated based on historical experience. For the quarter ended April 2, 2006, the Company based its expected stock price volatility on its market-based implied volatility, including historical implied volatility behavior, to construct a volatility term structure to equal the contractual terms of the options. Prior to October 3, 2005, the Company’s expected stock price volatility was based on historical experience. The Company’s risk-free rate of return was based on constant maturity rates provided by the U.S. Treasury. The expected life was based on historical experience.

Net cash proceeds from the exercise of stock options were $2.0 million and $1.3 million for the three months ended April 2, 2006 and April 3, 2005, respectively, and $3.0 million and $2.2 million for the six months ended April 2, 2006 and April 3, 2005, respectively. The Company’s policy is to issue shares from its authorized shares upon the exercise of stock options. The income tax benefit realized from stock option exercises for the three months ended April 2, 2006 and April 3, 2005 was $0.3 million and $0.2 million, respectively, and for the six months ended April 2, 2006 and April 3, 2005 was $0.5 million and $0.3 million, respectively.

5. Earnings (Loss) Per Share

Basic earnings (loss) per share (EPS) excludes dilution and is computed by dividing net income (loss) available to common stockholders by the weighted average number of common shares and the weighted average number of shares of exchangeable stock (exchangeable shares) of the Company’s former subsidiary, TTC, outstanding for the period. The exchangeable shares were non-voting and 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. As of April 3, 2005, all exchangeable shares (as adjusted for stock splits), were converted into the Company’s common stock. Diluted EPS is computed by dividing net income (loss) by the weighted average number of common shares outstanding, the weighted average number of exchangeable shares, and dilutive potential common shares for the period. The Company includes as potential common shares the weighted average dilutive effects of outstanding stock options using the treasury stock method. However, due to a net loss for the three and six months ended April 3, 2005, the potential common shares are excluded since their inclusion would be anti-dilutive.

The following table sets forth the number of weighted average shares used to compute basic and diluted EPS:

	Three Months Ended					Six Months Ended
	April 2, 2006		April 3, 2005			April 2, 2006		April 3, 2005
	(in thousands, except per share data)

Numerator:
Income (loss) from continuing operations	$	8,105	$	(97,944	)	$	16,593	$	(91,084	)
Income (loss) from discontinued operations	859		(25,889		)	394		(24,846		)
Net income (loss)	$	8,964	$	(123,833	)	$	16,987	$	(115,930	)

Income (loss) from discontinued operations	0.02		(0.46		)	0.01		(0.44		)
Net income (loss)	$	0.16	$	(2.19	)	$	0.30	$	(2.05	)

Diluted earnings (loss) per share:
Income (loss) from continuing operations	$	0.14	$	(1.73	)	$	0.29	$	(1.61	)
Income (loss) from discontinued operations	0.02		(0.46		)	—		(0.44		)
Net income (loss)	$	0.16	$	(2.19	)	$	0.29	$	(2.05	)

For the three and six months ended April 2, 2006, 2.7 million and 3.8 million options were excluded from the calculation of dilutive potential common shares, respectively. These options were not included in the computation of dilutive potential common shares because the assumed proceeds per share exceeded the average market price per share for that period. Therefore, their inclusion would have been anti-dilutive. For the three and six months ended April 3, 2005, 5.4 million options were excluded from the calculations of dilutive potential common shares because their inclusion would have been anti-dilutive due to the net loss for the periods.

6. Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. Cash and cash equivalents totaled $39.6 million and $26.9 million as of April 2, 2006 and October 2, 2005, respectively.

7. Accounts Receivable – Net

Net accounts receivable consisted of the following as of April 2, 2006 and October 2, 2005:

	April 2, 2006			October 2, 2005
	(in thousands)

Billed	$	184,074		$	201,996
Unbilled	135,135			136,886
Contract retentions	8,862			7,908
Total accounts receivable – gross	328,071			346,790

Allowance for doubtful accounts	(30,345		)	(41,885		)
Total accounts receivable – net	$	297,726		$	304,905

Billings in excess of costs on uncompleted contracts	$	44,097		$	48,560

Billed accounts receivable represent amounts billed to clients that have not been collected. Unbilled accounts receivable represent revenue recognized but not yet billed pursuant to contract terms or billed after the accounting cut-off date. Substantially all unbilled receivables as of April 2, 2006 are expected to be billed and collected within 12 months. Contract retentions represent amounts withheld by clients until certain conditions are met or the project is completed, which may be several months or years. Allowances for doubtful accounts have been determined through reviews of specific amounts determined to be uncollectible and potential write-offs as a result of debtors that have filed for bankruptcy protection, plus an allowance for other amounts for which some potential loss is determined to be probable based on current events and circumstances.

The billed receivables related to federal government contracts were $61.5 million and $74.8 million as of April 2, 2006 and October 2, 2005, respectively. The federal government unbilled receivables were $49.3 million and $40.4 million as of April 2, 2006 and October 2, 2005, respectively. Other than the federal government, no single client accounted for more than 10% of the Company’s accounts receivable as of April 2, 2006 and October 2, 2005.

8. Reportable Segments

The Company currently manages its business in three reportable segments: resource management, infrastructure and communications. The Company’s management established these segments based upon the services provided, the different marketing strategies associated with these services and the specialized needs of their respective clients. The resource management segment provides engineering and consulting services primarily addressing water quality and availability, environmental restoration, productive reuse of defense facilities and strategic environmental resource planning. The infrastructure segment provides engineering, systems integration, program management and construction management services for the development, upgrading and replacement of civil security and communications infrastructure. The communications segment provides engineering, permitting, site acquisition and construction management services to state and local governments, telecommunications companies and cable operators.

As a result of the Company’s decision to exit the wireless communications business, the remaining portion of the communications business, known as the wired business, will represent a relatively small part of the Company’s overall business in future periods. The wired business serves clients and performs services that are similar in nature to those of the infrastructure business. These clients include state and local governments, telecommunications companies and cable operators, and the services include engineering, permitting, site acquisition and construction management. During the first quarter of fiscal 2006, the Company developed and started implementing the initial phase of a plan to combine operating units and re-align its management structure. In the second quarter of fiscal 2006, the Company continued to implement the plan by re-aligning finance leadership, defining strategic and mid-year plan objectives, and analyzing management information reporting requirements. The Company expects to continue this implementation during the remainder of fiscal 2006, and will continue to assess the impact, if any, of this plan on its reportable segment requirements.

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. The Company’s management evaluates the performance of these reportable segments based upon their respective income from operations before the effect of any acquisition-related amortization. All inter-company balances and transactions are eliminated in consolidation.

The following tables set forth summarized financial information concerning the Company’s reportable segments:

9. Major Clients

For the three months ended April 2, 2006 and April 3, 2005, the Company generated 10.8% and 14.5% of its revenue, respectively, from the U.S. Army Corps of Engineers. For the six months ended April 2, 2006 and April 3, 2005, the Company generated 8.8% and 12.8% of its revenue, respectively, from the U.S. Army Corps of Engineers. All three segments reported revenue from state and local government and commercial clients. Only resource management and infrastructure segments reported revenue from the federal government.

The following table presents revenue by client sector:

	Three Months Ended				Six Months Ended
	April 2, 2006		April 3, 2005		April 2, 2006		April 3, 2005
	(in thousands)
Client Sector
Federal government	$	160,901	$	156,984	$	335,351	$	310,371
State and local government	53,486		42,952		111,405		95,614

Total	$	318,892	$	297,517	$	660,084	$	607,183

10. Comprehensive Income

The Company includes two components in its comprehensive income: net income (loss) during a period and other comprehensive income. Other comprehensive income consists of translation gains and losses from subsidiaries with functional currencies different than the Company’s reporting currency.

For the three and six months ended April 2, 2006, comprehensive income was $8.2 million and $16.2 million, respectively. For the three and six months ended April 3, 2005, comprehensive loss was $124.1 million and $115.7 million, respectively. For both the three and six months ended April 2, 2006, the Company realized a net translation loss of $0.7 million. For the three and six months ended April 2, 2005, the Company realized a net translation loss of $0.3 million and a net translation gain of $0.2 million, respectively.

11. Litigation

The Company is subject to certain claims and lawsuits typically filed against the engineering, consulting and construction profession, alleging primarily professional errors or omissions. The Company carries professional liability insurance, subject to certain deductibles and policy limits, against such claims. However, in some actions, parties are seeking damages that exceed the Company’s insurance coverage or for which the Company is not insured. Management’s opinion is that the resolution of its current claims will not have a material adverse effect on the Company’s financial position, results of operations or cash flows.

The Company continues to be involved in the contract dispute with Horsehead Industries, Inc., doing business as Zinc Corporation of America (ZCA). In April 2002, a Washington County Court in Bartlesville, Oklahoma dismissed with prejudice the Company’s counter-claims relating to receivables due from ZCA and other costs. In December 2002, the Court rendered a judgment for $4.1 million and unquantified legal fees against the Company in this dispute. In February 2004, the Court quantified the previous award and ordered the Company to pay approximately $2.6 million in ZCA’s attorneys’ and consultants’ fees and expenses, together with post-judgment interest.

The Company has posted bonds and filed appeals with respect to the earlier judgments. On December 27, 2004, the Court of Civil Appeals of the State of Oklahoma rendered a decision relating to certain aspects of the Company’s appeals. In its decision, the Court vacated the $4.1 million verdict against the Company. In addition, the Court upheld the dismissal of the Company’s counter-claims. The Court has not yet ruled on the status of ZCA’s attorneys’ and consultants’ fees and expenses. Several legal alternatives remain available to both parties including appeals to the Oklahoma Supreme Court. On January 18, 2005, both the Company and ZCA filed petitions for rehearing with the Oklahoma Court of Civil Appeals. Although the Company’s legal counsel in these matters continues to believe that a favorable outcome is reasonably possible, final outcome of these matters cannot yet be accurately predicted. As a result, the Company continues to maintain $4.1 million in accrued liabilities relating to

the original judgment, and a $2.6 million accrual for ZCA’s attorneys’ and consultants’ fees and expenses. Once the legal proceedings relating to ZCA are finally resolved, accruals will be adjusted accordingly.

12. Lease Exit Costs

In connection with the continuing consolidation of certain operations, and in accordance with SFAS No. 146, Accounting for Costs Associated with Exit or Disposal Activities, the Company recorded certain charges related to the abandonment of certain leased facilities in fiscal 2004 and 2005. These amounts were recorded as selling, general and administrative expenses and are expected to be fully paid by December 2013. These facilities are no longer in use, and the estimated costs are net of reasonably estimated sublease income. During the first quarter of fiscal 2006, the Company reached a favorable settlement relating to a lease for premises previously vacated. Consequently, the Company adjusted the lease exit accrual by $0.8 million to account for this change. The Company did not record any additional charges in the first half of fiscal 2006 as there were no other charges required to be accrued by SFAS No. 146.

The following is a summary of lease exit accrual activity:

	October 2, 2005		Reserve Utilization			April 2, 2006
	(in thousands)

Resource management	$	260	$	(60	)	$	200
Infrastructure	3,020		(1,210		)	1,810
Total	$	3,280	$	(1,270	)	$	2,010

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q, including Management’s Discussion and Analysis of Financial Condition and Results of Operations, contains forward-looking statements regarding future events and our future results that are subject to the safe harbor provisions created under the Securities Act of 1933 and the Securities Exchange Act of 1934. These statements are based on current expectations, estimates, forecasts and projections about the industries in which we operate and the beliefs and assumptions of our management. Words such as “expects,” “anticipates,” “targets,” “goals,” “projects,” “intends,” “plans,” “believes,” “seeks,” “estimates,” “continues,” “may,” variations of such words, and similar expressions are intended to identify such forward-looking statements. In addition, any statements that refer to projections of our future financial performance, our anticipated growth and trends in our businesses, and other characterizations of future events or circumstances are forward-looking statements. Readers are cautioned that these forward-looking statements are only predictions and are subject to risks, uncertainties and assumptions that are difficult to predict, including those identified below, as well as under the heading “Risk Factors,” and elsewhere herein. Therefore, actual results may differ materially and adversely from those expressed in any forward-looking statements. We undertake no obligation to revise or update any forward-looking statements for any reason.

OVERVIEW

We are a leading provider of consulting, engineering and technical services focused on water resource management and civil, security and communications infrastructure. We serve our clients by defining problems and developing innovative and cost-effective solutions. These services span the lifecycle of a project and include research and development, applied science and technology, engineering design, program management, construction, construction management, and operations and maintenance.

Since our initial public offering in December 1991, we have increased the size and scope of our business, expanded our service offerings and diversified our client base and the markets we serve through strategic acquisitions and internal growth. We expect to focus on internal growth, and to continue to pursue complementary acquisitions that expand our geographic reach and increase the breadth and depth of our service offerings to address existing and emerging markets. As of April 2, 2006, we had approximately 7,000 full-time equivalent employees worldwide, located primarily in North America in approximately 250 locations.

In the first half of fiscal 2006, we sold one operating unit in the communications segment and one operating unit in the resource management segment. We also discontinued the operations of another operating unit in the communications segment. See “Acquisitions and Divestitures” below. The results from these operating units have been reported as discontinued operations for all the reporting periods. Accordingly, the following discussions generally reflect summary results from our continuing operations unless otherwise noted. However, the net income and net income per share discussions include the impact of discontinued operations.

Our results of operations for the first half of fiscal 2006 were impacted by the adoption of Statement of Financial Accounting Standards (SFAS) No. 123 (revised 2004), Share-Based Payment (SFAS 123R) which requires us to recognize a non-cash expense related to the fair value of our stock-based compensation awards. Under the fair value recognition provisions of SFAS 123R, stock-based compensation cost is estimated at the grant date based on the value of the award and is recognized as expense ratably over the requisite service period of the award. Determining the appropriate fair value model and calculating the fair value of stock-based awards at the grant date requires judgment, including estimates of stock price volatility, forfeiture rates and expected option life. We elected to use the modified prospective transition method of adoption, which requires us to include this stock-based compensation charge in our results of operations beginning in the first quarter of 2006 without adjusting prior periods to include stock-based compensation expense. As a result of adopting SFAS 123R on October 3, 2005, our income from continuing operations before income tax expense for the three and six months ended April 2, 2006 included charges of $1.2 million and $2.2 million for stock-based compensation expense, respectively.

We derive our revenue from fees for professional and technical services. As a service company, we are labor-intensive rather than capital-intensive. Our revenue is driven by our ability to attract and retain qualified and productive employees, identify business opportunities, secure new and renew existing client contracts, provide outstanding services to our clients and execute projects successfully. Our income is derived from our ability to

generate revenue and collect cash under our contracts in excess of our subcontractor costs, other contract costs, and selling, general and administrative (SG&A) expenses.

We provide our services to a diverse base of federal, and state and local government agencies, as well as commercial and international clients. The following table presents the approximate percentage of our revenue, net of subcontractor costs, by client sector:

	Three Months Ended				Six Months Ended
	April 2, 2006		April 3, 2005		April 2, 2006		April 3, 2005
Client Sector
Federal government	45.9	%	49.6	%	45.4	%	47.7	%
State and local government	18.6		14.2		18.6		15.9
Commercial	34.9		36.2		35.3		36.0
International	0.6		—		0.7		0.4
	100.0	%	100.0	%	100.0	%	100.0	%

We currently manage our business in three reportable segments: resource management, infrastructure and communications. Management established these segments based upon the services provided, the different marketing strategies associated with these services and the specialized needs of their respective clients. Our resource management segment provides engineering and consulting services primarily addressing water quality and availability, environmental restoration, productive reuse of defense facilities and strategic environmental resource planning. Our infrastructure segment provides engineering, systems integration, program management and construction management services for the development, upgrading and replacement of civil security and communications infrastructure. Our communications segment provides engineering, permitting, site acquisition and construction management services to state and local governments, telecommunications companies and cable operators.

As a result of our decision to exit the wireless communications business, the remaining portion of the communications business, known as our wired business, will represent a relatively small part of our overall business in future periods. Our wired business serves clients and performs services that are similar in nature to those of our infrastructure business. These clients include state and local governments, telecommunications companies and cable operators, and the services include engineering, permitting, site acquisition and construction management. During the first quarter of fiscal 2006, we developed and started implementing the initial phase of a plan to combine operating units and re-align the management structure. In the second quarter of fiscal 2006, we continued to implenment the plan by re-aligning finance leadership, defining strategic and mid-year plan objectives, and analyzing management information reporting requirements. We expect to continue this implementation during the remainder of fiscal 2006, and will continue to assess the impact, if any, of this plan on our reportable segment requirements.

The following table presents the approximate percentage of our revenue, net of subcontractor costs, by reportable segment:

	Three Months Ended				Six Months Ended
	April 2, 2006		April 3, 2005		April 2, 2006		April 3, 2005
Reportable Segment
Resource management	62.3	%	63.8	%	62.3	%	63.3	%
Infrastructure	33.0		33.0		32.9		33.2
Communications	4.7		3.2		4.8		3.5
	100.0	%	100.0	%	100.0	%	100.0	%

Contract revenue and contract costs are recorded primarily using the percentage-of-completion (cost-to-cost) method. Under this method, revenue is recognized in the ratio that contract costs incurred bear to total estimated costs. Revenue and profit on these contracts are subject to revision throughout the duration 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.

Our services are billed under three principal types of contracts: fixed-price, time-and-materials, and cost-plus. The following table presents the approximate percentage of our revenue, net of subcontractor costs, by contract type:

	Three Months Ended				Six Months Ended
	April 2, 2006		April 3, 2005		April 2, 2006		April 3, 2005
Contract Type
Fixed-price	21.8	%	30.6	%	28.1	%	32.1	%
Time-and-materials	51.4		51.0		48.9		48.9
Cost-plus	26.8		18.4		23.0		19.0
	100.0	%	100.0	%	100.0	%	100.0	%

In the course of providing our services, we routinely subcontract services. Generally, these subcontractor costs are passed through to our clients and, in accordance with industry practice and generally accepted accounting principles (GAAP) in the United States, are included in revenue. Because subcontractor services can change significantly from project to project, changes in revenue may not be indicative of our business trends. Accordingly, we also report revenue less the cost of subcontractor services, and our discussion and analysis of financial condition and results of operations uses revenue, net of subcontractor costs, as the point of reference.

Our other contract costs include professional compensation and related benefits, together with certain direct and indirect overhead costs such as rents, utilities and travel. Professional compensation represents the majority of these costs. Our SG&A expenses are comprised primarily of marketing and bid and proposal costs, and our corporate headquarters’ costs related to the executive offices, corporate finance, accounting, administration and information technology. Most of these costs are unrelated to specific client projects and can vary as expenses are incurred to support corporate activities and initiatives.

Our revenue, expenses and operating results may fluctuate significantly from quarter to quarter as a result of numerous factors, including:

• Unanticipated changes in contract performance that may affect profitability, particularly with contracts that are fixed-price or have funding limits;

• The seasonality of the spending cycle of our public sector clients, notably the federal government, and the spending patterns of our commercial sector clients;

• Budget constraints experienced by our federal, state and local government clients;

• Acquisitions or the integration of acquired companies;

• Divestiture or discontinuance of operating units;

• Employee hiring, utilization and turnover rates;

• The number and significance of client contracts commenced and completed during a quarter;

• Creditworthiness and solvency of clients;

• The ability of our clients to terminate contracts without penalties;

• Delays incurred in connection with a contract;

• The size, scope and payment terms of contracts;

• Contract negotiations on change orders and collections of related accounts receivable;

• The timing of expenses incurred for corporate initiatives;

• Reductions in the prices of services offered by our competitors;

• Costs related to threatened or pending litigation;

• Changes in accounting rules; and

• General economic or political conditions.

We experience seasonal trends in our business. Our revenue is typically lower in the first quarter of our fiscal year, primarily due to the Thanksgiving, Christmas and, in certain years, New Year’s holidays that fall within the first quarter. Many of our clients’ employees, as well as our own employees, take vacations during these holidays. This results in fewer billable hours worked on projects and, correspondingly, less revenue recognized. Our revenue is typically higher in the second half of the fiscal year, due to weather conditions during spring and summer that result in higher billable hours. In addition, our revenue is typically higher in the fourth quarter of the fiscal year due to the federal government’s fiscal year-end spending. However, we do not anticipate this typical increase in year-end federal spending in fiscal 2006, especially in domestic programs, primarily due to the diversion of federal funding toward military actions in Iraq and elsewhere.

TREND ANALYSIS

General. To improve the profitability of our operations, we substantially completed the wind-down and divestiture of non-core businesses in the second quarter of fiscal 2006. Consequently, our operating results for the second quarter of fiscal 2006 reflect continued improvement compared to the same quarter last year. In comparing the second quarters of fiscal 2006 and 2005, it is important to note that revenue and income from operations for the fiscal 2005 period were comparatively low due to various charges, including the goodwill impairment in that quarter as described below. Consequently, the revenue growth rates for fiscal 2006 as compared to fiscal 2005 are significantly higher than the underlying business trends would indicate. In the third and fourth quarters of fiscal 2006, we expect moderate revenue growth from both federal, and state and local government clients, as well as revenue growth from commercial clients that is consistent with the general trends of the U.S. economy.

Federal Government. In the second quarter of fiscal 2006, we experienced slight revenue growth in our federal government business compared to the same quarter last year. The growth was primarily due to an increase in U.S. Department of Energy (DOE) work, together with U.S. Department of Defense (DoD) projects in Iraq. The growth was partially offset by reduced workload with other federal clients, such as the Federal Aviation Administration (FAA) and the National Aeronautics and Space Administration (NASA). Overall, we believe that our federal government business will experience slight growth in fiscal 2006 due in part to the unexploded ordnance (UXO) project in Iraq and increased Base Realignment and Closure (BRAC) spending.

State and Local Government. Our state and local government business experienced growth in the second quarter of fiscal 2006 compared to the same quarter last year. This was due in large part to increased workload under various civil infrastructure and fiber-to-the-premises projects. Most states are forecasting budget surpluses in fiscal 2006, and we believe that our revenue from state and local government clients will continue to grow through the remainder of fiscal 2006.

Commercial. In the second quarter of fiscal 2006, our commercial business also contributed to our revenue growth due to an upturn in the U.S. economy. Capital spending and discretionary environmental project funding increased in the first half of fiscal 2006, and we believe this improvement will continue through the second half of the year. In the longer term, we believe our commercial business will continue to follow the general trends of the U.S. economy.

ACQUISITIONS AND DIVESTITURES

Acquisitions. In the second quarter of fiscal 2006, one of our infrastructure operating units acquired the net assets of two engineering companies for a combined purchase price of $1.8 million. The purchase price consisted of cash and notes payable, and the acquisitions were accounted for as purchases. Accordingly, the purchase price of the net assets acquired was allocated to assets and liabilities acquired based on fair values. The excess of the purchase price over the fair value of the net tangible and identifiable intangible assets resulted in goodwill of $0.9 million. These acquisitions were not considered material and the acquired businesses did not have a material impact on our Company’s financial position, results of operations or cash flows for the three and six months ended April 2, 2006.

Divestitures. In the second quarter of fiscal 2006, we finalized an agreement to sell Vertex Engineering Services, Inc. (VES), an operating unit in the resource management segment. In the first quarter of fiscal 2006, we sold Tetra Tech Canada Ltd. (TTC), an operating unit in the communications segment. In addition, we ceased all revenue producing activities for Whalen & Company, Inc. (WAC), an operating unit in the communications segment. Accordingly, these three operating units have been reported as discontinued operations for all reporting periods. For the three months ended April 2, 2006 and April 3, 2005, discontinued operations did not generate a significant amount of revenue. For the six months ended April 2, 2006 and April 3, 2005, discontinued operations generated a total of $9.7 million and $34.0 million of revenue, respectively.

RESULTS OF OPERATIONS

Overall, our results for the second quarter of fiscal 2006 improved over those of the second quarter last year. The improvement resulted primarily from the wind-down of our non-core businesses and our focus on project performance to enhance the profitability of our future results. The results for the second quarter of fiscal 2005 included goodwill and other intangible asset impairment charges, lease exit costs, long-lived asset impairment charges, contract losses and bad debt expense. The results in fiscal 2006 did not reflect similar charges.

For the three and six months ended April 2, 2006, revenue increased $21.4 million, or 7.2%, and $52.9 million, or 8.7%, compared to the three and six months ended April 3, 2005, respectively. Overall, we experienced a broad-based revenue growth in both periods. Our federal government business with the EPA, DoD and DOE continued to increase, particularly with the work related to Hurricane Katrina, Iraqi reconstruction and UXO. Our state and local workload also experienced growth in civil infrastructure and fiber-to-the-premises projects. To a lesser extent, our commercial business increased due to an upturn in the U.S. economy.

For the three and six months ended April 2, 2006, revenue, net of subcontractor costs, increased $16.8 million, or 7.6%, and $20.7 million, or 4.6%, compared to the three and six months ended April 3, 2005, respectively, for the reasons described above. In addition, we experienced higher subcontracting requirements due to a change in our project mix related to our federal work compared to the same periods last year, particularly with the Iraqi reconstruction projects in the first quarter.

For the three and six months ended April 2, 2006, other contract costs decreased $8.0 million, or 4.0%, and $11.2 million, or 2.9%, compared to the three and six months ended April 3, 2005, respectively. The decrease resulted from our stronger emphasis on project and overhead cost controls and contract risk management. As a result, we improved the alignment of costs to our revenue base through significant reductions in project cost overruns and, to a lesser extent, overhead costs. The decrease was partially offset by increased costs to support revenue growth. For the three and six months ended April 2, 2006, as a percentage of revenue, net of subcontractor costs, other contract costs were 80.4% and 80.5%, respectively, compared to 90.2% and 86.8% for the three and six months ended April 3, 2005.

For the three and six months ended April 2, 2006, gross profit increased $24.8 million, or 114.4%, and $31.9 million, or 54.1%, compared to the three and six months ended April 3, 2005, respectively. The increase resulted primarily from the exit of certain non-core businesses, contract risk management, overhead efficiency, as well as the broad-based revenue growth. In addition, we did not experience contract charges similar to those in the second quarter of fiscal 2005. For the three and six months ended April 2, 2006, as a percentage of revenue, net of subcontractor costs, gross profit was 19.6% and 19.5%, respectively, compared to 9.8% and 13.2% for the three and six months ended April 3, 2005.

For the three and six months ended April 2, 2006, SG&A expenses decreased $7.6 million, or 20.1%, and $3.6 million, or 5.9%, compared to the three and six months ended April 3, 2005, respectively. In fiscal 2005, we incurred significant bad debt expenses, lease exit costs, asset impairment charges, legal expenses and, to a lesser

extent, charges related to the requirements of the Sarbanes-Oxley Act of 2002, and the amendment of our debt arrangements. These charges were not incurred, or were significantly lower, in the current fiscal year. The overall decrease was partially offset by higher SG&A expenses resulting from the growth of our business and increased marketing and business development costs. In addition, we adopted SFAS 123R under which we recognized $1.2 million and $2.2 million of stock-based compensation expense for the three and six months ended April 2, 2006, respectively. For the three and six months ended April 2, 2006, as a percentage of revenue, net of subcontractor costs, SG&A expenses were 12.8% and 12.3% compared to 17.2% and 13.7% for the three and six months ended April 3, 2005, respectively. Our SG&A expenses may continue to vary as we continue implementation of our ERP system and fund growth initiatives in fiscal 2006.

Based on a significant adverse change in the business environment, loss of key personnel and planned reduction of business activities in our infrastructure segment, we concluded in the second quarter of fiscal 2005 that an interim goodwill impairment analysis was required. Further, because of the immediate change in financial condition and results from the infrastructure segment, the more permanent nature of these changes, and our decision in the second quarter of fiscal 2005 to reduce the size of the infrastructure business, we did not believe it was appropriate to wait three months until July 1, 2005 to perform the annual goodwill analysis. In the second quarter of fiscal 2005, we performed an interim test of goodwill for impairment in our infrastructure segment as prescribed by SFAS No. 142, Goodwill and Other Intangible Assets, which included a downward forecast of our future operating income and cash flows. As a result, we recognized a non-cash impairment charge of $105.6 million related to goodwill and other intangible assets. No impairment charge was recognized in the current fiscal year.

For the three and six months ended April 2, 2006, net interest expense decreased $1.0 million, or 34.5%, and $1.2 million, or 22.9%, compared to the three and six months ended April 3, 2005, respectively. The decrease resulted from lower borrowings and increased interest income, partially offset by an increase in interest rates. The lower borrowings were primarily a result of positive cash flow from operations.

For the three and six months ended April 2, 2006, income tax expense increased $33.0 million, or 123.3%, and $34.7 million, or 157.4%, compared to the three and six months ended April 3, 2005, respectively. The increase was primarily due to the recognition of income in the current fiscal year compared to the loss in the prior year. The tax rate increased to 43.3% for the six months ended April 2, 2006 from 19.5% for the same period last year. The change in the tax rate was primarily due to the non-deductibility of the majority of the goodwill impairment charge recognized in fiscal 2005 and, to a lesser extent, the SFAS 123R expense for incentive stock options incurred in fiscal 2006.

For the three months ended April 2, 2006 and April 3, 2005, income from discontinued operations was $0.9 million and loss from discontinued operations was $25.9 million, respectively. For the six months ended April 2, 2006 and April 3, 2005, income from discontinued operations was $0.4 million and loss from discontinued operations was $24.8 million, respectively. In connection with the sale of a discontinued operation, we recognized a net gain of $1.1 million and $1.4 million for the three and six months ended April 2, 2006, respectively. Discontinued operations generated an insignificant amount of revenue for the three months ended April 2, 2006 and April 3, 2005. Discontinued operations generated $9.7 million and $34.0 million of revenue for six months ended April 2, 2006 and April 3, 2005, respectively.

For the three and six months ended April 2, 2006, revenue, net of subcontractor costs, increased $7.2 million, or 5.1%, and $8.4 million, or 3.0%, compared to the three and six months ended April 3, 2005, respectively. The growth was primarily due to increased work with state and local government, commercial and federal clients, particularly the DOE and the U.S. Environmental Protection Agency (EPA). The increase was partially offset by the wind-down of an operating unit that had performed construction work outside of the segment’s normal scope of services, together with a decline in our DoD work due to increased subcontracting requirements for Iraqi reconstruction.

For the three and six months ended April 2, 2006, other contract costs decreased $1.7 million, or 1.4%, and $1.4 million, or 0.6%, compared to the three and six months ended April 3, 2005, respectively. The decrease was primarily due to the recognition of contract losses in the prior year from one operating unit that performed fixed-price construction work. The decrease was partially offset by increased costs to support revenue growth. To a lesser extent, the decrease was also offset by a loss reserve for the completion of certain fixed-price projects. We guaranteed performance for these projects on behalf of a third-party company under a U.S. Small Business Administration program, and that company was financially unable to complete the projects on schedule and budget. For the three months ended April 2, 2006, the charges totaled $2.8 million, of which $1.2 million was recorded to SG&A expense since it represented bad debt expense on accounts receivable. For the three and six months ended April 2, 2006, as a percentage of revenue, net of subcontractor costs, other contract costs were 80.9% and 81.0%, compared to 86.3% and 83.8% for the three and six months ended April 3, 2005, respectively.

For the three and six months ended April 2, 2006, gross profit increased $8.9 million, or 46.1%, and $9.8 million, or 21.4%, compared to the three and six months ended April 3, 2005, respectively, for the reasons described above. For the three and six months ended April 2, 2006, as a percentage of revenue, net of subcontractor costs, gross profit was 19.1% and 19.0%, compared to 13.7% and 16.2% for the three and six months ended April 3, 2005, respectively.

For the three and six months ended April 2, 2006, revenue, net of subcontractor costs, increased $5.5 million, or 7.6%, and $5.6 million, or 3.8%, compared to the three and six months ended April 3, 2005, respectively. The increase resulted primarily from the growth in state and local government work in fiscal 2006. In addition, we experienced a revenue decline in fiscal 2005 caused by the closing and consolidation of non-performing operations. The increase was partially offset by the revenue decline in commercial work and federal business with the FAA and NASA.

For the three and six months ended April 2, 2006, other contract costs decreased $6.0 million, or 8.8%, and $8.9 million, or 6.7%, compared to the three and six months ended April 3, 2005, respectively. The decrease was primarily due to increased emphasis on contract risk management and the reduction of workforce and fixed facility costs. The decrease was partially offset by the increased costs to support revenue growth. For the three and six months ended April 2, 2006, as a percentage of revenue, net of subcontractor costs, other contract costs were 79.5% and 79.9%, compared to 93.8% and 88.9% for the three and six months ended April 3, 2005, respectively.

For the three and six months ended April 2, 2006, gross profit increased $11.6 million, or 257.1%, and $14.5 million, or 88.0%, compared to the three and six months ended April 3, 2005, respectively, for the reasons described above. For the three and six months ended April 2, 2006, as a percentage of revenue, net of subcontractor costs, gross profit was 20.5% and 20.1%, compared to 6.2% and 11.1% for the three and six months ended April 3, 2005, respectively.

For the three and six months ended April 2, 2006, revenue, net of subcontractor costs, increased $4.1 million, or 58.4%, and $6.7 million, or 42.3%, compared to the three and six months ended April 3, 2005, respectively. The increase resulted from the growth in our fiber-to-the-premises projects. In addition, we experienced revenue reduction in the second quarter of fiscal 2005 as we consolidated and closed facilities that performed civil construction work.

For the three and six months ended April 2, 2006, other contract costs decreased $0.3 million, or 3.0%, and $1.0 million, or 5.1%, compared to the three and six months ended April 3, 2005, respectively. In fiscal 2005, we incurred costs related to our exit from non-core businesses, including loss contract charges and lease impairment costs. These costs were not incurred in fiscal 2006. The decrease was partially offset by the increased costs to support revenue growth. For the three and six months ended April 2, 2006, as a percentage of revenue, net of subcontractor costs, other contract costs were 80.1% and 79.7%, compared to 130.7% and 119.6% for the three and six months ended April 3, 2005, respectively.

For the three and six months ended April 2, 2006, gross profit increased $4.4 million, or 202.9%, and $7.7 million, or 247.4%, compared to the three and six months ended April 3, 2005, respectively, for the reasons described above. For the three and six months ended April 2, 2006, as a percentage of revenue, net of subcontractor

costs, gross profit was 19.9% and 20.3%, compared to gross loss of 30.7% and 19.6% for the three and six months ended April 3, 2005, respectively.

Liquidity and Capital Resources

The following discussion generally reflects the impact of both continuing and discontinued operations unless otherwise noted.

Working Capital. As of April 2, 2006, our working capital was $135.4 million, an increase of $13.8 million from $121.6 million as of October 2, 2005. This increase was primarily related to our business growth and the net income generated during the six months ended April 2, 2006. Cash and cash equivalents totaled $39.6 million as of April 2, 2006, compared to $26.9 million as of October 2, 2005.

Operating and Investing Activities. For the six months ended April 2, 2006, net cash of $15.1 million was provided by operating activities and $4.2 million was used in investing activities. For the six months ended April 3, 2005, net cash of $10.2 million was provided by operating activities and $10.7 million was used in investing activities. The improvement resulted from the successful management of our cash flow through better contract payment terms and timely project billings and collections. Our net accounts receivable from continuing operations decreased $7.2 million, or 2.4%, to $297.7 million as of April 2, 2006 from $304.9 million as of October 2, 2005.

Capital Expenditures. Our capital expenditures for the six months ended April 2, 2006 and April 3, 2005 were $5.9 million and $5.5 million, respectively. This increase resulted from investment in our growing businesses, partially offset by lower capitalized costs associated with our ERP system, which is now mid-way through the implementation phase.

Debt Financing. We have a credit agreement with several financial institutions, which was amended in July 2004, December 2004, May 2005 and March 2006 (Credit Agreement). The Credit Agreement provides a revolving credit facility (Facility) of up to $150.0 million. As part of the Facility, we may request standby letters of credit up to the aggregate sum of $100.0 million. The Facility matures on July 21, 2009, or earlier at our discretion, upon payment of all amounts due under the Facility.

As of April 2, 2006, we had no borrowings under the Facility. Standby letters of credit under the Facility totaled $11.6 million as of that date.

In May 2001, we issued two series of senior secured notes in the aggregate amount of $110.0 million (Senior Notes) under a note purchase agreement that was amended in September 2001, April 2003, December 2004, May 2005 and March 2006 (Note Purchase Agreement). The Series A Notes, in the original amount of $92.0 million, are payable semi-annually and mature on May 30, 2011. The Series B Notes, in the original amount of $18.0 million, are payable semi-annually and mature on May 30, 2008. Based on our satisfaction of certain covenant compliance criteria, the Series A Notes and Series B Notes currently bear interest at 7.28% and 7.08% per annum, respectively.

As of April 2, 2006, the outstanding principal balance on the Senior Notes was $89.7 million. Scheduled principal payments of $16.7 million are due on May 30, 2006 and, accordingly, were included in current portion of long-term obligations. The remaining $73.0 million was included in long-term obligations as of April 2, 2006.

The May 2005 amendments to the Credit Agreement and Note Purchase Agreement revised our financial covenants and increased the restrictions on our ability to incur other debt, repurchase stock, engage in acquisitions or dispose of assets. Specifically, the maximum leverage ratio (defined as the ratio of funded debt to adjusted EBITDA) is 2.5x for the quarter ended April 2, 2006 and 2.25x for each quarter thereafter. As of April 2, 2006, our leverage ratio was 1.34x. Our minimum net worth is defined as the sum of (a) base net worth, (b) 50% of positive net income since April 3, 2005, and (c) 100% of net cash proceeds of any equity issued since April 3, 2005. As of the quarter ended April 2, 2006, our minimum net worth covenant was $268.4 million and actual net worth was $326.8 million.

Further, these agreements contain other restrictions, including but not limited to, the creation of liens and the payment of dividends on our capital stock (other than stock dividends). Borrowings under the Credit Agreement and Note Purchase Agreement are secured by our accounts receivable, the stock of certain of our subsidiaries and our cash, deposit accounts, investment property and financial assets. There were no significant changes to the Credit Agreement or Facility since October 2, 2005. Although we

were not in compliance with certain financial covenants during fiscal 2005 before the May 2005 amendments, we have met all compliance requirements from May 2005 through April 2, 2006. We expect to be in compliance over the next 12 months.

Capital Requirements. We expect that internally generated funds, our existing cash balances and borrowing capacity under the Credit Agreement will be sufficient to meet our capital requirements for the next 12 months.

Acquisitions. We continuously evaluate the marketplace for strategic acquisition opportunities. Historically, due to our reputation, size, geographic presence and range of services, we have had numerous opportunities to acquire both privately-held companies and subsidiaries or divisions of publicly-held companies. Once an opportunity is identified, we examine the effect an acquisition may have on our long-range business strategy, as well as on our results of business operations. Generally, we proceed with an acquisition if we believe that the acquisition will have a positive effect on future operations and could strategically expand our service offerings. As successful integration and implementation are essential to achieve favorable results, no assurance 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 may acquire other businesses that we believe are synergistic and will ultimately increase our revenue and net income, strengthen our strategic goals, provide critical mass with existing clients, and further expand our lines of service. These factors may contribute to a purchase price that results in a recognition of goodwill.

Inflation. 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 due to the average duration of our projects and our ability to negotiate prices as contracts end and new contracts begin. However, current general economic conditions may impact our client base, and, as such, may impact our clients’ creditworthiness and our ability to collect cash to meet our operating needs.

Financial Market Risks

We currently utilize no material derivative financial instruments that expose us to significant market risk. We are exposed to interest rate risk under our Credit Agreement. Effective as of April 3, 2005, we may borrow on our Facility, at our option, at either (a) a base rate (the greater of the federal funds rate plus 0.50% per annum or the bank’s reference rate) plus a margin which ranges from 0.65% to 1.225% per annum, or (b) a eurodollar rate plus a margin which ranges from 1.65% to 2.25% per annum.

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 July 21, 2009 or earlier at our discretion upon payment in full of loans and other obligations.

Our outstanding Senior Notes bear interest at a fixed rate. As of February 14, 2006, the Series A Notes bear interest at 7.28% per annum and are payable at $13.1 million per year through May 2011. As of February 14, 2006, the Series B Notes bear interest at 7.08% per annum and are payable at $3.6 million per year through May 2008. If interest rates increased by 1.0% per annum, the fair value of the Senior Notes could decrease by $2.5 million. If interest rates decreased by 1.0% per annum, the fair value of the Senior Notes could increase by $2.6 million.

We currently anticipate repaying $17.8 million of our outstanding indebtedness in the next 12 months, of which $16.7 million is for scheduled principal payments on the Senior Notes and $1.1 million is related to other debt. Assuming we do repay the remaining $1.1 million ratably during the next 12 months and no borrowings under the Facility for the next 12 months, our annual interest expense could increase or decrease by $0.01 million when our average interest rate increases or decreases by 1% per annum. However, there can be no assurance that we will, or will be able to, repay our debt in the prescribed manner. In addition, we could incur additional debt under the Facility to meet our operating needs or to finance future acquisitions.

RISK FACTORS

Set forth below and elsewhere in this Report and in other documents we file with the SEC are risks and uncertainties that could cause actual results to differ materially from the results contemplated by the forward-looking statements contained in this Report.

Our quarterly and annual operating results may fluctuate significantly, which could have a negative effect on the price of our common stock

Our quarterly and annual revenue, expenses and operating results may fluctuate significantly because of a number of factors, including:

• Unanticipated changes in contract performance that may affect profitability, particularly with contracts that are fixed-price or have funding limits;

• The seasonality of the spending cycle of our public sector clients, notably the federal government, and the spending patterns of our commercial sector clients;

• Budget constraints experienced by our federal, state and local government clients;

• Acquisitions or the integration of acquired companies;

• Divestiture or discontinuance of operating units;

• Employee hiring, utilization and turnover rates;

• The number and significance of client contracts commenced and completed during the quarter;

• Creditworthiness and solvency of clients;

• The ability of our clients to terminate contracts without penalties;

• Delays incurred in connection with a contract;

• The size, scope and payment terms of contracts;

• Contract negotiations on change orders and collections of related accounts receivable;

• The timing of expenses incurred for corporate initiatives;

• Reductions in the prices of services offered by our competitors;

• Threatened or pending litigation;

• The impairment of our goodwill;

• Changes in accounting rules; and

• General economic or political conditions.

Variations in any of these factors could cause significant fluctuations in our operating results from quarter to quarter and could result in net losses.

We derive the majority of our revenue from government agencies, and any disruption in government funding or in our relationship with those agencies could adversely affect our business

In the second quarter of fiscal 2006, we derived approximately 64.5% of our revenue, net of subcontractor costs, from contracts with federal, state and local government agencies. Federal government agencies are among our most significant clients. These agencies generated 45.9% of our revenue, net of subcontractor costs, in the second quarter of fiscal 2006 as follows: 25.4% from the DoD, 7.2% from the EPA, 6.2% from the DOE, and 7.1% from various other federal agencies. A significant amount of this revenue is derived under multi-year contracts, many of which are appropriated on an annual basis. As a result, at the beginning of a project, the related contract may be only partially funded, and additional funding is normally committed only as appropriations are made in each subsequent year. Our backlog includes only the projects that have funding appropriated.

The demand for our government-related services is generally related to the level of government program funding. Accordingly, the success and further development of our business depends, in large part, upon the continued funding of these government programs and upon our ability to obtain contracts under these programs. There are several factors that could materially affect our government contracting business, including the following:

• Changes in and delays or cancellations of government programs, requirements or appropriations;

• Budget constraints or policy changes resulting in delay or curtailment of expenditures relating to the services we provide;

• Re-competes of government contracts;

• The timing and amount of tax revenue received by federal, state and local governments;

• Curtailment of the use of government contracting firms;

• The increasing preference by government agencies for contracting with small and disadvantaged businesses;

• Competing political priorities and changes in the political climate with regard to the funding or operation of the services we provide;

• The adoption of new laws or regulations affecting our contracting relationships with the federal, state or local governments;

• Unsatisfactory performance on government contracts by us or one of our subcontractors, negative government audits, or other events that may impair our relationship with the federal, state or local governments;

• A dispute with or improper activity by any of our subcontractors; and

• General economic or political conditions.

These and other factors could cause government agencies to delay or cancel programs, to reduce their orders under existing contracts, to exercise their rights to terminate contracts or not to exercise contract options for renewals or extensions. Any of these actions could have a material adverse effect on our revenue or timing of contract payments from these agencies.

The loss of key personnel or our inability to attract and retain qualified personnel could significantly disrupt our business

We depend upon the efforts and skills of our executive officers, senior managers and consultants. With limited exceptions, we do not have employment agreements with any of these individuals. The loss of the services of any of these key personnel could adversely affect our business. Although we have obtained non-compete agreements from certain principals and stockholders of companies we have acquired, we generally do not have non-compete or employment agreements with key employees who were once equity holders of these companies. Further, many of our non-compete agreements have expired. We do not maintain key-man life insurance policies on any of our executive officers or senior managers. In addition, our consolidation efforts within our infrastructure business and our shift to a more centralized structure for the operation of our overall business have resulted, and could result further, in the loss of key employees.

Our future growth and success depends on our ability to attract and retain qualified scientists and engineers. The market for these professionals is competitive and we may not be able to attract and retain such professionals. We typically grant these employees stock options and a reduction in our stock price could impact our ability to retain these professionals.

Our use of the percentage-of-completion method of accounting could result in reduction or reversal of previously recorded revenue and profits

We account for most of our contracts on the percentage-of-completion method of accounting. Generally, our use of this method results in recognition of revenue and profit ratably over the life of the contract, based on the proportion of costs incurred to date to total costs expected to be incurred. The effect of revisions to revenue and estimated costs, including the achievement of award and other fees, is recorded when the amounts are known and can be reasonably estimated. Such revisions could occur in any period and their effects could be material. The

uncertainties inherent in the estimating process make it possible for actual costs to vary from estimates, including reductions or reversals of previously recorded revenue and profit, and such differences could be material.

The value of our common stock could continue to be volatile

Our common stock has experienced substantial price volatility. In addition, the stock market has experienced extreme price and volume fluctuations that have affected the market price of many companies and that have often been unrelated to the operating performance of these companies. The overall market and the price of our common stock may continue to fluctuate greatly. The trading price of our common stock may be significantly affected by various factors, including:

• Quarter-to-quarter variations in our financial results, including revenue, profits, day sales in receivables, backlog, and other measures of financial performance or financial condition;

• Announcements by us or our competitors of significant events, including acquisitions;

• Resolution of threatened or pending litigation;

• Changes in investors’ and analysts’ perceptions of our business or any of our competitors’ businesses;

• Investors’ and analysts’ assessments of reports prepared or conclusions reached by third parties;

• Changes in environmental legislation;

• Investors’ perceptions of our performance of services in countries in which the U.S. military is engaged, including Afghanistan and Iraq;

• Broader market fluctuations; and

• General economic or political conditions.

Additionally, volatility or a lack of positive performance in our stock price may adversely affect our ability to retain key employees, many of whom are granted stock options, the value of which is dependent on the performance of our stock price.

Our failure to properly manage projects may result in additional costs or claims

Our engagements often involve large-scale, complex projects. The quality of our performance on such projects depends in large part upon our ability to manage the relationship with our clients, and to effectively manage the project and deploy appropriate resources, including third-party contractors and our own personnel, in a timely manner. If we miscalculate the resources or time we need to complete a project with capped or fixed fees, or the resources or time we need to meet contractual milestones, our operating results could be adversely affected. Further, any defects or errors, or failures to meet our clients’ expectations, could result in claims for damages against us. Our contracts generally limit our liability for damages that arise from negligent acts, errors, mistakes or omissions in rendering services to our clients. However, we cannot be sure that these contractual provisions will protect us from liability for damages in the event we are sued.

Over the past two fiscal years, we have experienced significant project cost overruns on the performance of fixed-price construction work, other than that associated with our federal government projects. We have bid on and accepted contracts with unfavorable terms and conditions; performed on projects without properly defined scopes; maintained low levels of productivity and entered into projects that were outside our normal scope of services. Although we have implemented procedures intended to address these issues, no assurance can be given that we will not experience project management issues in the future.

There are risks associated with our acquisition strategy that could adversely impact our business and operating results

A significant part of our growth strategy is to acquire other companies that complement our lines of business or that broaden our technical capabilities and geographic presence. We expect to continue to acquire companies as an element of our growth strategy; however, our ability to make acquisitions is more restricted under the May 2005 amendments to our Credit Agreement and Note Purchase Agreement. Acquisitions involve certain known and unknown risks that could cause our actual growth or operating results to differ from our expectations or the expectations of securities analysts. For example:

• We may not be able to identify suitable acquisition candidates or to acquire additional companies on acceptable terms;

• We compete with others to acquire companies which may result in decreased availability of, or increased price for, suitable acquisition candidates;

• We may not be able to obtain the necessary financing, on favorable terms or at all, to finance any of our potential acquisitions;

• We may ultimately fail to consummate an acquisition even if we announce that we plan to acquire a company;

• We may not be able to retain key employees of an acquired company which could negatively impact that company’s future performance;

• We may fail to successfully integrate or manage these acquired companies due to differences in business backgrounds or corporate cultures;

• If we fail to successfully integrate any acquired company, our reputation could be damaged. This could make it more difficult to market our services or to acquire additional companies in the future; and

• These acquired companies may not perform as we expect and we may fail to realize anticipated revenue and profits.

In addition, our acquisition strategy may divert management’s attention away from our primary service offerings, result in the loss of key clients or key employees, and expose us to unanticipated problems or legal liabilities, including responsibility as a successor-in-interest for undisclosed or contingent liabilities of acquired businesses or assets.

Further, acquisitions may also cause us to:

• Issue common stock that would dilute our current stockholders’ ownership percentage;

• Assume liabilities, including environmental liabilities;

• Record goodwill that will be subject to impairment testing and potential periodic impairment charges;

• Incur amortization expenses related to certain intangible assets;

• Lose existing or potential contracts as a result of conflict of interest issues;

• Incur large and immediate write-offs; or

• Become subject to litigation.

Finally, acquired companies that derive a significant portion of their revenue from the federal government and that do not follow the same cost accounting policies and billing practices as we do may be subject to larger cost disallowances for greater periods than we typically encounter. If we fail to determine the existence of unallowable costs and establish appropriate reserves in advance of an acquisition, we may be exposed to material unanticipated liabilities, which could have a material adverse effect on our business.

Downturns in the financial markets and reductions in state and local government budgets could negatively impact the capital spending of our clients and adversely affect our revenue and operating results

Downturns in the capital markets can impact the spending patterns of certain clients. Our state and local government clients may face budget deficits that prohibit them from funding new or existing projects. In addition, our existing and potential clients may either postpone entering into new contracts or request price concessions. Difficult financing and economic conditions may cause some of our clients to delay payments for services we perform, thereby increasing the average number of days our receivables are outstanding. Further, these conditions may result in the inability of some of our clients to pay us for services that we have already performed. If we are not able to reduce our costs quickly enough to respond to the revenue decline from these clients, our operating results may be adversely affected. Accordingly, these factors affect our ability to forecast with any accuracy our future revenue and earnings from business areas that may be adversely impacted by market conditions.

If we are not able to successfully manage our growth strategy, our business and results of operations may be adversely affected

Our expected future growth presents numerous managerial, administrative, operational and other challenges. Our ability to manage the growth of our operations will require us to continue to improve our management information systems and our other internal systems and controls. In addition, our growth will increase our need to attract, develop, motivate and retain both our management and professional employees. The inability of our management to effectively manage our growth or the inability of our employees to achieve anticipated performance could have a material adverse effect on our business.

Adverse resolution of an Internal Revenue Service examination process may harm our financial results

We are currently under examination by the Internal Revenue Service (IRS) for fiscal years 1997 through 2004. The major issue raised by the IRS relates to the research and experimentation (R&E) credits that we recognized during the years under examination. The amount of credits recognized for financial statement purposes represents the amount that we estimate will be ultimately realizable. Should the IRS determine that the amount of R&E credits to which we are entitled is more or less than the amount recognized, we will recognize an adjustment to the income tax accounts in the period in which the determination is made. This may have a material adverse effect on our financial results.

If we do not successfully implement our new enterprise resource planning system, our cash flows may be impaired and we may incur further costs to integrate or upgrade our systems

In fiscal 2004, we began implementation of a new company-wide enterprise resource planning (ERP) system, principally for accounting and project management. During fiscal 2006, we plan to convert several of our large operating units to our ERP system. In the event we do not complete the project successfully, we may experience difficulty in accurately and timely reporting certain revenue and cost data. During the ERP implementation process, we have experienced reduced cash flows due to temporary delays in issuing invoices to our clients, which has adversely affected the timely collection of cash. It is also possible that the cost of completing this project could exceed our current projections and negatively impact future operating results.

Our international operations expose us to risks such as foreign currency fluctuations and different business cultures, laws and regulations

During the second quarter of fiscal 2006, we derived approximately 0.6% of our revenue, net of subcontractor costs, from international clients. Some contracts with our international clients are denominated in foreign currencies. As such, these contracts contain inherent risks including foreign currency exchange risk and the risk associated with expatriating funds from foreign countries. In addition, certain expenses are also denominated in foreign currencies. If our revenue and expenses denominated in foreign currencies increases, our exposure to foreign currency fluctuations may also increase. We periodically enter into forward exchange contracts to mitigate such foreign currency exposures.

In addition, the different business cultures associated with international operations may not be fully appreciated before we sign an agreement, and thereby expose us to risk. Likewise, we need to understand prior to signing a contract international laws and regulations, such as foreign tax and labor laws, and U.S. laws and regulations applicable to companies engaging in business outside of the U.S., such as the Foreign Corrupt Practices Act. For these reasons, pricing and executing international contracts is more difficult and carries more risk than pricing and executing domestic contracts. Our experience has also shown that it is typically more difficult to collect on international work that has been performed and billed.

Our revenue from commercial clients is significant, and the credit risks associated with certain of these clients could adversely affect our operating results

In the second quarter of fiscal 2006, we derived approximately 34.9% of our revenue, net of subcontractor costs, from commercial clients. We rely upon the financial stability and creditworthiness of these clients. To the extent the credit quality of these clients deteriorates or these clients seek bankruptcy protection, our ability to collect our receivables, and ultimately our operating results, may be adversely affected. Periodically, we have experienced bad debt losses.

As a government contractor, we are subject to a number of procurement rules and regulations and other public sector liabilities, any deemed violation of which could lead to fines or penalties or lost business

We must comply with and are affected by laws and regulations related to the formation, administration and performance of government contracts. For example, we must comply with Federal Acquisition Regulations, the Truth in Negotiations Act, Cost Accounting Standards and DoD security regulations, as well as many other rules and regulations. These laws and regulations affect how we do business with our clients and, in some instances, impose added costs on our business. A violation of these laws and regulations could result in the imposition of fines and penalties against us or the termination of our contracts. Moreover, as a federal government contractor, we must maintain our status as a responsible contractor. Failure to do so could lead to suspension or debarment, making us ineligible for federal government contracts and potentially ineligible for state and local government contracts.

Most of our government contracts are awarded through a regulated competitive bidding process, and the inability to complete existing government contracts or win new government contracts over an extended period could harm our operations and adversely affect our future revenue

Most of our government contracts are awarded through a regulated competitive bidding process. Some government contracts are awarded to multiple competitors, which increases overall competition and pricing pressure and may require us to make sustained post-award efforts to realize revenue under the government contracts. In addition, government clients can generally terminate or modify their contracts at their convenience. Moreover, even if we are qualified to work on a new government contract, we might not be awarded the contract because of existing government policies designed to protect small businesses and underrepresented minority contractors. The inability to complete existing government contracts or win new government contracts over an extended period could harm our operations and adversely affect our future revenue.

A negative government audit could result in an adverse adjustment of our revenue and costs, could impair our reputation, and could result in civil and criminal penalties

Government agencies, such as the Defense Contract Audit Agency, routinely audit and investigate government contractors. These agencies review a contractor’s performance under its contracts, cost structure and compliance with applicable laws, regulations and standards. If the agencies determine through these audits or reviews that we improperly allocated costs to specific contracts, they will not reimburse us for these costs. Therefore, an audit could result in substantial adjustments to our revenue and costs.

Further, although we have internal controls in place to oversee our government contracts, no assurance can be given that these controls are sufficient to prevent isolated violations of applicable laws, regulations and standards. If the agencies determine that we or one of our subcontractors engaged in improper conduct, we may be subject to civil or criminal penalties and administrative sanctions, payments, fines and suspension or prohibition from doing business with the government, any of which could materially affect our financial condition. In addition, we could suffer serious harm to our reputation.

Our business and operating results could be adversely affected by our inability to accurately estimate the overall risks, revenue or costs on a contract

We generally enter into three principal types of contracts with our clients: fixed-price, time-and-materials, and cost-plus. Under our fixed-price contracts, we receive a fixed price irrespective of the actual costs we incur and, consequently, we are exposed to a number of risks. These risks include underestimation of costs, problems with new technologies, unforeseen costs or difficulties, delays beyond our control, price increases for materials, and economic and other changes that may occur during the contract period. Under our time-and-materials contracts, we are paid for labor at negotiated hourly billing rates and for other expenses. Profitability on these contracts is driven by billable headcount and cost control. Many of our time-and-materials contracts are subject to maximum contract values and, accordingly, revenue relating to these contracts is recognized as if these contracts were fixed-price contracts. Under our cost-plus contracts, some of which are subject to contract ceiling amounts, we are reimbursed for allowable costs and fees, which may be fixed or performance-based. If our costs exceed the contract ceiling or are not allowable under the provisions of the contract or any applicable regulations, we may not be able to obtain reimbursement for all such costs.

Accounting for a contract requires judgments relative to assessing the contract’s estimated risks, revenue and costs, and on making judgments on other technical issues. Due to the size and nature of many of our contracts, the estimation of overall risk, revenue and cost at completion is complicated and subject to many variables. Changes in underlying assumptions, circumstances or estimates may also adversely affect future period financial performance. If we are unable to accurately estimate the overall revenue or costs on a contract, then we may experience a lower profit or incur a loss on the contract.

Our backlog is subject to cancellation and unexpected adjustments, and is an uncertain indicator of future operating results

Our backlog as of April 2, 2006 was approximately $941.1 million. We cannot guarantee that the revenue projected in our backlog will be realized or, if realized, will result in profits. In addition, project cancellations or scope adjustments may occur, from time to time, with respect to contracts reflected in our backlog. For example, certain of our contracts with the federal government and other clients are terminable at the discretion of the client with or without cause. These types of backlog reductions could adversely affect our revenue and margins. Accordingly, our backlog as of any particular date is an uncertain indicator of our future earnings.

The consolidation of our client base could adversely impact our business

Recently, there has been consolidation within our current and potential commercial client base, particularly in the telecommunications industry. Future consolidation activity could have the effect of reducing the number of our current or potential clients, and lead to an increase in the bargaining power of our remaining clients. This potential increase in bargaining power could create greater competitive pressures and effectively limit the rates we charge for our services. As a result, our revenue and margins could be adversely affected.

If our partners fail to perform their contractual obligations on a project, we could be exposed to legal liability, loss of reputation and profit reduction or loss on the project

We occasionally enter into subcontracts, joint ventures and other contractual arrangements so that we can jointly bid and perform on a particular project. Success on these joint projects depends in large part on whether our partners fulfill their contractual obligations satisfactorily. If any of our partners fails to satisfactorily perform their contractual obligations as a result of financial or other difficulties, we may be required to make additional investments and provide additional services in order to make up for our partner’s shortfall. If we are unable to adequately address our partner’s performance issues, then our client could terminate the joint project, exposing us to legal liability, loss of reputation and reduced profit or loss on the project. We recorded loss reserves for the completion of certain fixed-price projects in the second quarter of fiscal 2006. We guaranteed performance for these projects on behalf of a third-party company under a U.S. Small Business Administration program, and that company was financially unable to complete the projects on schedule and budget.

Our inability to find qualified subcontractors could adversely affect the quality of our service and our ability to perform under certain contracts

Under some of our contracts, we depend on the efforts and skills of subcontractors for the performance of certain tasks. Our reliance on subcontractors varies from project to project. In the second quarter of fiscal 2006, subcontractor costs comprised 25.5% of our revenue. The absence of qualified subcontractors with which we have a satisfactory relationship could adversely affect the quality of our service and our ability to perform under some of our contracts.

Changes in existing environmental laws, regulations and programs could reduce demand for our environmental services, which could cause our revenue to decline

A significant amount of our resource management business is generated either directly or indirectly as a result of existing federal and state laws, regulations and programs related to pollution and environmental protection. Accordingly, a relaxation or repeal of these laws and regulations, or changes in governmental policies regarding the funding, implementation or enforcement of these programs, could result in a decline in demand for environmental services that may have a material adverse effect on our revenue.

Our industry is highly competitive and we may be unable to compete effectively

We provide specialized consulting, engineering and technical services in the areas of resource management, infrastructure and communications to a broad range of government and commercial sector clients. The market for our services is highly competitive and we compete with many other firms. These firms range from small regional firms to large international firms. Some of our competitors have achieved substantially more market penetration in certain markets in which we compete. In addition, some of our competitors have substantially more experience, financial resources and/or financial flexibility than we do.

We compete for projects and engagements with a number of competitors that can vary from one to 100 firms. Historically, clients have chosen among competing firms based on technical capabilities, the quality and timeliness of the firm’s service, and geographic presence. If competitive pressures force us to make price concessions or otherwise reduce prices for our services, then our revenue and margins will decline and our results from operations would be harmed.

Restrictive covenants in our Credit Agreement and Note Purchase Agreement relating to our senior secured notes may restrict our ability to pursue certain business strategies

Our Credit Agreement and Note Purchase Agreement relating to our senior secured notes restrict our ability to, among other things:

• Incur additional indebtedness;

• Create liens securing debt or other encumbrances on our assets;

• Make loans or advances;

• Pay dividends or make distributions to our stockholders;

• Purchase or redeem our stock;

• Repay indebtedness that is junior to indebtedness under our Credit Agreement and Note Purchase Agreement;

• Acquire the assets of, or merge or consolidate with, other companies; and

• Sell, lease or otherwise dispose of assets.

Our Credit Agreement and Note Purchase Agreement also require that we maintain certain financial ratios, which we may not be able to achieve. We failed to meet these required financial ratios at the end of the second quarter of fiscal 2005. We obtained waivers of the technical defaults caused by these failures and amendments to these agreements in May 2005. The covenants in these agreements may impair our ability to finance future operations or capital needs or to engage in certain business activities.

Our services expose us to significant risks of liability and it may be difficult to obtain or maintain adequate insurance coverage

Our services involve significant risks of professional and other liabilities that may substantially exceed the fees we derive from our services. Our business activities could expose us to potential liability under various environmental laws and under workplace health and safety regulations. In addition, we sometimes assume liability by contract under indemnification agreements. We cannot predict the magnitude of such potential liabilities.

We obtain insurance from third parties to cover our potential risks and liabilities. It is possible that we may not be able to obtain adequate insurance to meet our needs, may have to pay an excessive amount for the insurance coverage we want, or may not be able to acquire any insurance for certain types of business risks.

Our liability for damages due to legal proceedings may harm our operating results or financial condition

We are a party to lawsuits in the normal course of business. Various legal proceedings are currently pending against us and certain of our subsidiaries alleging, among other things, breach of contract or tort in connection with the performance of professional services. We cannot predict the outcome of these proceedings with

certainty. In some actions, parties are seeking damages that exceed our insurance coverage or for which we are not insured. If we sustain damages that exceed our insurance coverage or that are not covered by insurance, there could be a material adverse effect on our business, operating results or financial condition.

Our failure to implement and comply with our safety program could adversely affect our operating results or financial condition

Our safety program is a fundamental element of our overall approach to risk management, and the implementation of the safety program is a significant issue in our dealings with our clients. We maintain an enterprise-wide group of health and safety professionals to help ensure that the services we provide are delivered safely and in accordance with standard work processes. Unsafe job sites and office environments have the potential to increase employee turnover, increase the cost of a project to our clients, expose us to types and levels of risk that are fundamentally unacceptable, and raise our operating costs. The implementation of our safety processes and procedures are monitored by various agencies and rating bureaus, and may be evaluated by certain clients in cases in which safety requirements have been established in our contracts. If we fail to meet these requirements, or to properly implement and comply with our safety program, there could be a material adverse effect on our business, operating results or financial condition.

Our inability to obtain adequate bonding could have a material adverse effect on our future revenues and business prospects

Many of our clients require bid and performance and surety bonds. These bonds indemnify the client should we fail to perform our obligations under the contract. If a bond is required for a particular project and we are unable to obtain an appropriate bond, we cannot pursue that project. In some instances, we are required to partner with a small or disadvantaged business to pursue certain federal or state contracts. In connection with these partnerships, we are sometimes required to utilize our bonding capacity to cover all of the payment and performance obligations under the contract with the client. We have a bonding facility but, as is typically the case, the issuance of bonds under that facility is at the surety’s sole discretion. Moreover, due to events that can negatively affect the insurance and bonding markets, bonding may be more difficult to obtain or may only be available at significant additional cost. There can be no assurance that bonds will continue to be available to us on reasonable terms. Our inability to obtain adequate bonding and, as a result, to bid on new work could have a material adverse effect on our future revenues and business prospects.

We may be precluded from providing certain services due to conflict of interest issues

Many of our clients are concerned about potential or actual conflicts of interest in retaining management consultants. Federal government agencies have formal policies against continuing or awarding contracts that would create actual or potential conflicts of interest with other activities of a contractor. These policies, among other things, may prevent us from bidding for or performing government contracts resulting from or relating to certain work we have performed. In addition, services performed for a commercial or government client may create a conflict of interest that precludes or limits our ability to obtain work from other public or private organizations. We have, on occasion, declined to bid on projects because of these conflicts of interest issues.

Changes in accounting for equity-related compensation could impact the way we use stock-based compensation to attract and retain employees

On October 2, 2005, we adopted Statement of Financial Account Standards (SFAS) No. 123 (revised 2004), Share-Based Payment (SFAS 123R), which requires the measurement and recognition of compensation expense for all stock-based compensation based on estimated fair values. As a result, our operating results for the second quarter of fiscal 2006 contain, and our operating results for future periods will contain, a charge for stock-based compensation related to employee stock options and the Employee Stock Purchase Plan. The application of SFAS 123R requires the use of an option-pricing model to determine the fair value of share-based payment awards. This determination of fair value is affected by our stock price as well as assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to, our expected stock price volatility over the term of the awards, and actual and projected employee stock option exercise behaviors. Option-pricing models were developed for use in estimating the value of traded options that have no vesting or hedging restrictions and are fully transferable. Because our employee stock options have certain characteristics that are significantly different from traded options, and because changes in the subjective assumptions can materially affect the estimated

value, in management’s opinion the existing valuation models may not provide an accurate measure of the fair value of our employee stock options. As a result of the adoption of SFAS 123R, our earnings for the second quarter of fiscal 2006 were lower than they would have been if we were not required to adopt SFAS 123R. The adoption of SFAS 123R will have an impact of approximately $4 million to $6 million on our results of operations in fiscal 2006.

Compliance with changing regulation of corporate governance and public disclosure will result in additional expenses

Changing laws, regulations and standards relating to corporate governance and public disclosure, including the Sarbanes-Oxley Act of 2002, new Securities and Exchange Commission (SEC) regulations, and Nasdaq Stock Market rules, are creating additional disclosure and other compliance requirements for us. We are committed to maintaining high standards of corporate governance and public disclosure. As a result, we intend to invest appropriate resources to comply with evolving standards, and this investment may result in increased general and administrative expenses and a diversion of management time and attention from revenue-generating activities to compliance activities.

Problems such as computer viruses or terrorism may disrupt our operations and harm our operating results

Despite our implementation of network security measures, our servers are vulnerable to computer viruses, break-ins and similar disruptions from unauthorized tampering with our computer systems. Any such event could have a material adverse effect on our business, operating results and financial condition. In addition, the effects of war or acts of terrorism could have a material adverse effect on our business, operating results and financial condition. The terrorist attacks on September 11, 2001 disrupted commerce and intensified uncertainty regarding the U.S. economy and other economies. The continued threat of terrorism and heightened security and military action in response to this threat, or any future acts of terrorism, may cause further disruptions and create further uncertainties. To the extent that such disruptions or uncertainties result in delays or cancellations of customer contracts, our business, operating results and financial condition could be materially and adversely affected.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Please refer to the information we have included under the heading “Financial Market Risks” in Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations, which is incorporated herein by reference.

Item 4. Controls and Procedures

Evaluation of disclosure controls and procedures and changes in internal control over financial reporting. As of April 2, 2006, we carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures. Based on our management’s evaluation (with the participation of our principal executive officer and principal financial officer), our principal executive officer and principal financial officer have concluded that, as of the end of the period covered by this Report, our disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act), were effective.

Changes in internal control over financial reporting. There was no change in our internal control over financial reporting during our second quarter of fiscal 2006 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

We are subject to certain claims and lawsuits typically filed against the engineering, consulting and construction profession, alleging primarily professional errors or omissions. We carry 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 our financial position, results of operations or cash flows.

We continue to be involved in the contract dispute with Horsehead Industries, Inc., doing business as Zinc Corporation of America (ZCA). In April 2002, a Washington County Court in Bartlesville, Oklahoma dismissed with prejudice our counter-claims relating to receivables due from ZCA and other costs. In December 2002, the Court rendered a judgment for $4.1 million and unquantified legal fees against us in this dispute. In February 2004, the Court quantified the previous award and ordered us to pay approximately $2.6 million in ZCA’s attorneys’ and consultants’ fees and expenses, together with post-judgment interest.

We have posted bonds and filed appeals with respect to the earlier judgments. On December 27, 2004, the Court of Civil Appeals of the State of Oklahoma rendered a decision relating to certain aspects of our appeals. In its decision, the Court vacated the $4.1 million verdict against us. In addition, the Court upheld the dismissal of our counter-claims. The Court has not yet ruled on the status of ZCA’s attorneys’ and consultants’ fees and expenses. Several legal alternatives remain available to both parties including appeals to the Oklahoma Supreme Court. On January 18, 2005, both we and ZCA filed petitions for rehearing with the Oklahoma Court of Civil Appeals. Although our legal counsel in these matters continues to believe that a favorable outcome is reasonably possible, final outcome of these matters cannot yet be accurately predicted. As a result, we continue to maintain $4.1 million in accrued liabilities relating to the original judgment, and a $2.6 million accrual for ZCA’s attorneys’ and consultants’ fees and expenses. Once the legal proceedings relating to ZCA are finally resolved, accruals will be adjusted accordingly.
