BUSINESS. Tetra Tech, Inc. is a leading provider of specialized management consulting and technical services in three principal business areas: resource management, infrastructure and communications. As a specialized management consultant, we assist our clients in defining problems and developing innovative and cost-effective solutions. Our management consulting services are complemented by our technical services. These technical services, which implement solutions, include research and development, applied science, engineering and architectural design, construction management, and operations and maintenance. Our clients include a diverse base of public and private organizations located in the United States and internationally. Since our initial public offering in December 1991, we have increased the size and scope of our business and have expanded our service offerings through a series of strategic acquisitions and internal growth. As of the end of our last fiscal year, we had more than 3,600 employees worldwide, 3,500 of whom are located in North America in more than 100 locations. In addition, we have established a presence in Asia, South America and Europe. From fiscal 1991 through fiscal 1998, we generated a net revenue compounded annual growth rate of approximately 34.2%, and achieved a net income compounded annual growth rate of approximately 36.4%. INDUSTRY OVERVIEW Due to increased competition, changing regulatory environments and rapid technological advancement, many organizations face new and complex challenges. Increasingly, these organizations are turning to professional services firms to assist them with addressing these challenges. Since each industry presents its own unique set of challenges, organizations often seek professional service firms with industry-specific expertise to analyze their problems and develop appropriate solutions. These solutions are then implemented by firms possessing the required engineering and technical service capabilities. Each of the following three business areas faces its own unique set of problems: RESOURCE MANAGEMENT. The world's natural resources, including water, air and soil, are interdependent, creating a delicate balance. Factors such as agricultural and residential development, commercial construction and industrialization often upset this balance. Public concern over environmental issues, especially water quality and availability, has been a driving force behind numerous laws and regulations that are designed to prevent environmental degradation and mandate restorative measures. To comply with environmental laws and regulations, respond to public pressure and attain operating efficiencies, public and private organizations are increasing their focus on resource management. Two areas particularly affected by these trends are water management and waste management. - Water Management. Insufficient water supplies, concern over the cost, quality and availability of water and the need in many parts of the world to replace aging infrastructure used to capture, safeguard and distribute water are critical social and economic concerns. According to the U.S. Environmental Protection Agency (EPA), contamination of groundwater and surface water resulting from agricultural, residential, commercial and industrial development is one of the most serious environmental problems facing the United States. To alleviate these social and economic concerns, public and private organizations seek water management advice. According to the ENVIRONMENTAL BUSINESS JOURNAL, the size of the consulting, engineering services and wastewater treatment segments of the water management industry totaled more than $30 billion in 1997. - Waste Management. In the past, many waste disposal practices caused significant environmental damage. Since the 1970s, more stringent controls on municipal and industrial waste have been established by governments around the world to protect the environment. Recently, the Federal government has committed approximately $15 billion to various environmental initiatives in an attempt to curb pollution, accelerate toxic waste cleanups and 2 combat other forms of pollution. Organizations seek waste management advice to comply with complex and evolving environmental regulations, to minimize the economic impact of waste generation and disposal, and to realize significant costs savings through increased operating efficiencies. INFRASTRUCTURE. Continued population and economic growth places significant strain on an overburdened infrastructure, thereby requiring additional development. This development includes water and wastewater treatment plants, roads, pipelines, communication and power networks, and educational, recreational and correctional facilities. Additionally, as existing facilities age, they require upgrading or replacement. Further, the trend toward privatization of infrastructure is causing public and private organizations that develop and maintain these facilities to evaluate their cost structures and establish more efficient systems. These factors drive the need for development and planning services that are often provided by consulting firms. According to the ENGINEERING NEWS-RECORD, the market opportunity in the United States for technical services in infrastructure development including water and wastewater, transportation, hazardous waste, and educational, recreational and correctional facilities, ranges from $15 to $20 billion. COMMUNICATIONS. Technological change and government deregulation have spurred sweeping changes in the communications industry. Local and long-distance telephone companies, cable operators and wireless service providers are penetrating each other's markets and trying to establish a foothold in new markets created by new technologies. For example, traditional cable operators are installing advanced capabilities such as digital cable, cable modem, cable telephony and other high-speed data transmission services. At the same time, various service providers are consolidating in order to offer their subscribers a comprehensive set of services and to maintain dominance in their markets. As these trends continue, network service providers will increasingly turn to professional service firms for advice and assistance in planning, deploying and maintaining their communications networks. Organizations within each of the above business areas face unique problems but often lack the internal resources and experience necessary to identify issues and evaluate possible solutions. As a result, many of these organizations rely on advice from outside management consultants. Most consulting companies provide limited front-end problem assessment and solution design and require clients to engage other engineering and technical services companies to implement recommended solutions. A significant opportunity exists for consulting companies that not only develop, but also implement, solutions. These professional service firms are often in the best position to help clients respond to the challenges they face. THE TETRA TECH SOLUTION Tetra Tech provides the specialized management consulting services that assist clients in identifying industry-specific problems and defining appropriate solutions. We also provide the technical services required to implement these solutions. We believe that we are a leader in this market and that the following factors distinguish us from our competitors: UNDERSTANDING CLIENT NEEDS. The ability to identify client needs is essential to strategic planning and execution. Even before the proposal process begins, we assist our clients by helping them define their business objectives and strategies and identify issues that are critical to their success. We strive to develop numerous contacts at various levels within our clients' organizations to help us identify the key issues from a variety of perspectives. We believe that our long history and exposure to a broad client base increase our awareness of the issues being confronted by organizations and thereby help us identify and solve our clients' problems. CAPITALIZING ON OUR EXTENSIVE TECHNICAL EXPERIENCE. Since our inception in 1966, we have provided innovative consulting and engineering services, historically focusing on cost-effective solutions to water resource management and environmental problems. We have been successful in leveraging this 3 foundation of scientific and engineering capabilities into other areas, including infrastructure and communications. Our services are provided by a wide range of professionals including: archaeologists, biologists, chemical engineers, chemists, civil engineers, computer scientists, economists, electrical engineers, environmental engineers, environmental scientists, geologists, hydrogeologists, mechanical engineers, oceanographers and toxicologists. Because of the experience that we have gained from thousands of completed projects, we often are able to apply proven solutions to client problems without the time-consuming process of developing new approaches. OFFERING A FULL RANGE OF SERVICES. Our depth of consulting and technical skills allows us to respond to client needs at every phase of a project, including initial planning, research and development, applied science, engineering and architectural design, and construction management. Once a particular project is completed, we are able to offer our clients additional value-added services such as operations and maintenance. Our expertise across industries and our broad service offerings enable us to be a single source provider to our clients. PROVIDING BROAD GEOGRAPHIC COVERAGE AND LOCAL EXPERTISE. We believe that proximity to our clients is instrumental to understanding their needs and delivering comprehensive services. We have significantly broadened our geographic presence in recent years through strategic acquisitions and internal growth. Our historical geographic base was primarily in the western portion of the United States. However, we currently have operations in more than 40 states. We have also increased our international presence, and we now have operations in Canada, Taiwan, the Philippines, Argentina, Chile, Brazil and the Czech Republic. COMPANY STRATEGY Our objective is to become the leading provider of specialized management consulting and technical services in our chosen business areas. To achieve this objective, we plan to continue the following primary strategies that we believe have been integral to our success: IDENTIFY AND EXPAND INTO NEW BUSINESS AREAS. We use our management consulting services and certain of our technical services as an entry point to evaluate and to enter new business areas. After our consulting practice is established in a new business area, we can expand our operations by offering additional technical services. For example, based on our provision of site acquisition services to communications industry participants, we identified infrastructure services within the communications industry as an appropriate area into which we could expand our operations. EXPAND SERVICE OFFERINGS AND GEOGRAPHIC PRESENCE THROUGH ACQUISITIONS. We believe that acquisition opportunities exist that will allow us to continue our growth in selected business areas, broaden our service offerings and extend our geographic presence. We intend to make acquisitions that will enable us to consolidate our position in certain key business areas, such as communications, or further strengthen our position in our more established service offerings. We believe that our reputation and public company status make us an attractive partner and provide us with an advantage in pursuing acquisitions. FOCUS ON GOVERNMENT PROJECTS. We intend to continue marketing to government organizations and bidding for government projects to stay on the leading edge of policy development. This experience helps us identify market opportunities and enhances our ability to serve other public and private clients. Additionally, government contracts provide more predictable revenues than private sector contracts. MANAGE INTERNAL FINANCIAL CONTROLS. We take a disciplined approach to monitoring, managing and improving our return on investment in each of our business areas through the prompt billing and collection of accounts receivables, the negotiation of favorable contract terms and the management of our contract performance to prevent cost overruns. We believe that this approach to managing our 4 financial affairs enables us to improve our cash position and thereby fund acquisitions and internal growth. LEVERAGE EXISTING CLIENT BASE. Some of our clients engage us to provide limited services. We believe that we can increase our revenue by selling additional services to our existing client base. For example, we may be able to secure an operations and maintenance contract after working with a client on the design and construction phases of a facility. In addition, we believe that our ability to offer a full spectrum of services will allow us to grow our business and compete more effectively for larger projects. SERVICES We provide our clients with comprehensive management consulting and technical services that focus on our clients' industry-specific needs. We offer these services individually or as part of our full service approach to problem solving. We are currently performing services under 1,000 active contracts, ranging from small site investigations to large, complex infrastructure projects. Our service offerings include: - MANAGEMENT CONSULTING to assist clients in identifying and addressing operational and competitive problems they face within their industries; - RESEARCH AND DEVELOPMENT to formulate solutions to complex problems and develop advanced computer simulation techniques for modeling problems, ranging from microscopic to global; - APPLIED SCIENCE to assess all aspects of problems and develop practical and cost-effective solutions through the application of new technology and data interpretation; - ENGINEERING AND ARCHITECTURAL DESIGN to provide services from concept development and initial planning and design through project completion; - CONSTRUCTION MANAGEMENT to provide experienced and specialized construction managers to assist clients in minimizing the risk of cost overruns, delays and contractual conflicts; and - OPERATIONS AND MAINTENANCE to allow clients to outsource routine functions, permitting them to streamline contractor relationships and reduce operating costs. BUSINESS AREAS We provide our services in the following three principal business areas: resource management, infrastructure and communications. RESOURCE MANAGEMENT One of our major concentrations is water resource management, where we have a leadership position in understanding the interrelationships of water quality and human activities. We support high priority government programs for water quality improvement, environmental restoration, productive reuse of defense facilities and strategic environmental resource planning. We provide comprehensive services, including management consulting, research and development, applied science, engineering and architectural design, construction management, and operations and maintenance. Our service offerings in the resource management business area are focused on the following project areas: SURFACE WATER PROJECTS: Public concern with the quality of rivers, lakes and streams as well as coastal and marine waters and the ensuing legislative and regulatory response is driving demand for our services. Over the past 32 years, we have developed a specialized set of technical skills that positions us to compete effectively for surface water and watershed management projects. We provide water resource services to government clients such as the 5 EPA, the Department of Defense (DOD) and the Department of Energy (DOE), and to a broad base of private sector clients including those in the chemical, pharmaceutical, utility, aerospace and petroleum industries. We also provide surface water services to state and local agencies, particularly in the area of watershed management. GROUNDWATER PROJECTS: Groundwater is the source of drinking water for approximately 50% of the U.S. population and accounts for approximately 25% of all water consumed for residential, industrial and agricultural purposes. Our activities in the groundwater field are diverse and typically include projects such as investigating and identifying sources of chemical contamination, examining the extent of contamination, analyzing the speed and direction of contamination migration, and designing and evaluating remedial alternatives. In addition, we conduct monitoring studies to assess the effectiveness of groundwater treatment and extraction wells. WASTE MANAGEMENT PROJECTS: We currently provide a wide range of engineering and consulting services for hazardous waste contamination and remediation projects, from initial site assessment through design and implementation phases of remedial solutions. In addition, we perform risk assessments to determine the probability of adverse health effects that may result from exposure to toxic substances. We also provide waste minimization and pollution prevention services, and evaluate the effectiveness of innovative technologies and novel solutions to environmental problems. NUCLEAR ENVIRONMENTAL PROJECTS: The DOE's nuclear weapons plants and research laboratories face a wide variety of environmental challenges including groundwater and surface water contamination, hazardous waste management and environmental compliance. Our services include environmental impact analyses and documentation, environmental audits and risk assessments, regulatory compliance support, groundwater characterization, remedial investigation/feasibility studies, and project management and oversight. Our environmental analyses provide the DOE with information it requires in order to make decisions regarding the storage or disposition of surplus materials from dismantled nuclear weapon components. REGULATORY COMPLIANCE PROJECTS: Our regulatory compliance services include advising our clients on the full spectrum of regulatory requirements under the Resource Conservation and Recovery Act, the Clean Water Act, the Clean Air Act, the National Environmental Policy Act and other environmental laws. Although we provide services to both public and private clients, our current emphasis is on providing regulatory compliance services to the Army, Navy and Air Force. INFRASTRUCTURE In the infrastructure area, we focus on the development of water resource projects, institutional facilities, commercial, recreational and leisure facilities and transportation projects. These facilities are an essential part of everyday life and also sustain economic activity and the quality of life. Our engineers, architects and planners work in partnership with our clients to provide adequate infrastructure development within their financial constraints. We assist clients with infrastructure projects by providing management consulting, engineering and architectural design, construction management, and operations and maintenance. Our service offerings in the infrastructure business area are focused on the following project areas: WATER RESOURCE PROJECTS: Our technical services are applied to all aspects of water quantity and quality management ranging from stormwater management through drainage and flood control projects to major water and wastewater treatment plants. Our experience includes planning, design and construction services for drinking water projects, the design of water treatment facilities and reservoirs, and the design of distribution systems including pipelines and pump 6 stations. Our capabilities are also applied to specialized technical challenges associated with the design and construction of fisheries and hatcheries worldwide. INSTITUTIONAL FACILITIES PROJECTS: We provide architectural engineering and construction services for projects including site planning for land development, complete architectural design, interior design, civil/structural engineering and mechanical/electrical engineering of multi-story facilities. We have completed engineering and construction projects for a wide range of clients with specialized needs such as security systems, clean rooms, laboratories and emergency preparedness facilities. COMMERCIAL, RECREATIONAL AND LEISURE FACILITIES PROJECTS: We specialize in the planning and design of water-related entertainment and leisure facilities from theme park attractions to large marine aquariums. Our projects also include hotels, parks, visitor centers and marinas.

CLIENTS We have developed a diverse client base of hundreds of clients both in the public and private sectors. During fiscal 1998, the DOD, EPA and DOE accounted for 26.2%, 17.1% and 3.5%, respectively, of our net revenue. Although agencies of the Federal government are among our most significant clients, we often support multiple programs within a single Federal agency. Our private sector clients include companies in the chemical, mining, pharmaceutical, aerospace, automotive, petroleum, communications and utility industries. No private sector client accounted for more than 10% of our net revenue in fiscal 1998. 8 The following table presents a list of representative clients in our three primary business areas: REPRESENTATIVE CLIENTS - --------------------- ------------------------------------------------------------------------------------------- BUSINESS AREA FEDERAL GOVERNMENT STATE, COUNTY AND LOCAL PRIVATE - --------------------- ----------------------------- ----------------------------- ----------------------------- RESOURCE MANAGEMENT U.S. Environmental Protection California Department of Lockheed Martin Corporation; Agency; U.S. Air Force; U.S. Health Services; Washington Merck & Co.; General Electric Navy; U.S. Army; U.S. Coast Department of Ecology; Prince Company; Westwood Squibb Guard; U.S. Forest Service Georges County, Maryland; Pharmaceuticals, Inc.

In fiscal 1998, 27.3%, 30.6% and 42.1% of our net revenue was derived from fixed-price, fixed-rate time and materials, and cost-reimbursement plus fixed fee and award fee contracts, respectively. Under a fixed-price contract, the client agrees to pay a specified price for our performance of the entire contract. Fixed-price contracts carry certain inherent risks, including risks of losses from underestimating costs, delays in project completion, problems with new technologies and economic and other changes that may occur over the contract period. Consequently, the profitability of fixed-price contracts may vary substantially. The amount of the fee received for a cost-reimbursement and award fee contract partially depends upon the government's discretionary periodic assessment of our performance on that contract. Our various clients determine which type of contract we enter into for a particular engagement. Some contracts made with the Federal government are subject to annual approval of funding. Federal government agencies may impose spending restrictions that limit the continued funding of our existing contracts with the Federal government and may limit our ability to obtain additional contracts. These limitations, if significant, could have a material adverse effect on us. To date, spending limitations have not had a significant effect on us. All contracts made with the Federal government may be terminated by the government at any time, with or without cause. 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 may prevent us in certain cases from bidding for or performing contracts resulting from or relating to certain work we have performed for the government. In addition, services performed for a private client may create conflicts of interest that preclude or limit our ability to obtain work for another private organization. We attempt to identify actual or potential conflicts of interest and to minimize the 9 possibility that such conflicts would affect our work under current contracts or our ability to compete for future contracts. We have, on occasion, declined to bid on a project because of an existing potential conflict of interest. However, we have not experienced disqualification during a bidding or award negotiation process by any government or private client as a result of a conflict of interest. Our contracts with the Federal government are subject to audit by the government, primarily by the Defense Contract Audit Agency (DCAA). The DCAA generally seeks to (1) identify and evaluate all activities which either contribute to, or have an impact on, proposed or incurred costs of government contracts; (2) evaluate the contractor's policies, procedures, controls and performance; and (3) prevent or avoid wasteful, careless and inefficient production or service. To accomplish this, the DCAA examines our internal control systems, management policies and financial capability, evaluates the accuracy, reliability and reasonableness of our cost representations and records, and assesses compliance by us with Cost Accounting Standards and defective-pricing clauses found within the Federal Acquisition Regulations. The DCAA also performs the annual review of our overhead rates and assists in the establishment of our final rates. This review focuses on the allowability of cost items and the allowability and applicability of Cost Accounting Standards. The DCAA also audits cost-based contracts, including the close-out of those contracts. The DCAA also reviews all types of proposals, including those of award, administration, modification and repricing. Factors considered are our cost accounting system, estimating methods and procedures, and specific proposal requirements. Operational audits are also performed by the DCAA. A review of our operations at every major organizational level that has a significant effect on the performance of future government contracts is also conducted during the proposal review period. During the course of its audit, the DCAA may disallow costs if it determines that we improperly accounted for such costs in a manner inconsistent with Cost Accounting Standards. Under a government contract, only those costs that are reasonable, allocable and allowable are recoverable. A disallowance of costs by the DCAA could have a material adverse effect on us. In September 1995, we acquired PRC Environmental Management, Inc. (EMI). The Defense Contract Audit Agency (DCAA) recently completed an audit of EMI for the fiscal years 1987 through 1995. As a result of the completed audit and our negotiations with the DCAA, the DCAA disallowed approximately $2.9 million in costs. Because we were aware of these issues prior to completing the acquisition, we established a sufficient reserve and, consequently, the disallowance did not have a material adverse effect on our business. Due to the severity of the legal remedies available to the government, including the required payment of damages and/or penalties, criminal and civil sanctions, and debarment, we maintain controls to avoid the occurrence of fraud and other unlawful activity. In addition, we maintain preventative audit programs to ensure appropriate control systems and mitigate control weaknesses. We provide our services under contracts, purchase orders or retainer letters. Our policy provides that, where possible, all contracts will be in writing. We bill all of our clients periodically based on costs incurred, on either an hourly-fee basis or on a percentage of completion basis, as the project progresses. Generally, our contracts do not require that we provide performance bonds. A performance bond, issued by a surety company, guarantees the contractor's performance under the contract. If the contractor defaults under the contract, the surety will, in its discretion, step in to finish the job or pay the client the amount of the bond. If the contractor does not have a performance bond and defaults in the performance of a contract, the contractor is responsible for all damages resulting from the breach of contract. These damages include the cost of completion, together with possible consequential damages such as lost profits. To date, we have not incurred material damages beyond the coverage of any performance bond. 10 Most of our agreements permit termination by the clients upon payment of fees and expenses through the date of the termination. MARKETING We utilize both a centralized corporate marketing department and local marketing groups within each of our operating units. Our corporate marketing department assists management in establishing our business plan, our target markets and an overall marketing strategy. The corporate marketing department also identifies and tracks the development of large Federal programs, positions us for new business areas, selects appropriate partners, if any, for new projects and assists in the bid process for new projects. We market throughout the organizations we target, focusing primarily on senior representatives in government organizations and senior management in private companies. In addition, the corporate marketing department supports marketing activities firm-wide by coordinating corporate promotional and professional activities, including appearances at trade shows, direct mailings, telemarketing and public and media relations. We also perform marketing activities through our local offices. We believe that these offices have a greater understanding of local environmental issues, laws and regulations and, therefore, can better target their marketing activities. These marketing activities are coordinated by full time marketing staff located in certain of our offices. These activities include meetings with potential clients and state, county and municipal regulators, presentations to civic and professional organizations and seminars on current regulatory topics. COMPETITION The market for our services is highly competitive. We compete with many other firms, ranging from small local firms to large national firms that may have greater financial and marketing resources. We perform a broad spectrum of engineering and consulting services across the resource management, infrastructure and communications business areas. Services within these business areas are provided to a client base which includes Federal agencies, such as the DOD, the DOE, the Department of the Interior, the EPA and the U.S. Postal Service, state and local agencies, and the private sector. Our competition varies and is a function of the business areas in which, and client sectors for which, we perform our services. The range of competitors for any one procurement can vary from 10 to 100 firms, depending upon the relative value of the project, the financial terms and risks associated with the work, and any restrictions placed upon competition by the client. Historically, clients have chosen among competing firms based primarily on the quality and timeliness of the firm's service. However, we believe that price has become an increasingly important competitive factor. We believe that if this trend continues it could have a material adverse effect on our operating margins and profitability. We believe that our principal competitors include, in alphabetical order, Black & Veatch LLP; Brown & Caldwell; Castle Tower Corporation; Camp, Dresser & McKee; CH2M Hill Companies Ltd., Dames & Moore Group; EA Engineering, Science & Technology, Inc.; Earth Tech, Inc.; ICF Kaiser International, Inc.; IT Group Inc.; Mastec, Inc.; Montgomery Watson; OSP Consultants, Inc.; Roy F. Weston, Inc.; and URS Greiner Corporation. BACKLOG At October 4, 1998, our gross revenue backlog was approximately $405.0 million, compared to $217.5 million at September 28, 1997. We include in gross revenue backlog only those contracts for which funding has been provided and work authorizations have been received. We estimate that approximately $329.6 million of the gross revenue backlog at October 4, 1998 will be recognized during fiscal 1999. No assurance can be given that all amounts included in backlog will ultimately be realized, even if evidenced by written contracts. For example, certain of our contracts with the Federal 11 government and other clients are terminable at will. If any of these clients terminate their contracts prior to completion, we would not recognize revenue. ENVIRONMENTAL LEGISLATION Our clients have become subject to an increasing number of frequently overlapping Federal, state and local laws concerned with the protection of the environment, as well as regulations promulgated by administrative agencies pursuant to these laws. We provide services with respect to Federal environmental laws, and regulations including: the Clean Water Act; the Resource Conservation and Recovery Act; CERCLA; the National Environmental Policy Act; the Safe Drinking Water Act; and other laws. POTENTIAL LIABILITY AND INSURANCE Our business activities could expose us to potential liability under various environmental laws such as CERCLA. In addition, we occasionally contractually assume liability under indemnification agreements. We cannot predict the magnitude of such potential liabilities. We currently maintain comprehensive general liability, umbrella and professional liability insurance policies. These policies are "claims made" policies. This means that only claims made during the term of the policy are covered. If we terminate our policies and do not obtain retroactive coverage, we would be uninsured for claims made after termination even if based on events or acts that occurred during the term of the policy. We obtain insurance coverage through a broker who is experienced in the engineering field. The broker, together with our Risk Manager, periodically review the adequacy of our insurance programs. However, because there are various exclusions and retentions under our insurance policies, there can be no assurance that all potential liabilities will be covered by our insurance. Further, in the event we expand our services into new markets, we may not be able to obtain insurance coverage for such activities or, if insurance is obtained, the dollar amount of any liabilities incurred could exceed our insurance coverage. We evaluate the risk associated with uninsured claims. If we determine that an uninsured claim has potential liability, we establish an appropriate reserve. A reserve is not established if we determine that the claim has no merit. Our historic levels of insurance coverage and reserves have been adequate. However, a partially or completely uninsured claim, if successful and of significant magnitude, could have a material adverse effect on our business. EMPLOYEES At October 4, 1998, we had 3,662 total employees or 3,077 full-time equivalent employees. Of the 3,662 total employees, 2,144 are professionals. Our professional staff includes archaeologists, biologists, chemical engineers, chemists, civil engineers, computer scientists, economists, electrical engineers, environmental engineers, environmental scientists, geologists, hydrogeologists, mechanical engineers, oceanographers, toxicologists and project managers. Our ability to retain and expand our staff of qualified professionals will be an important factor in determining our future growth and success. Three employees of one of our subsidiaries will be represented by a labor organization. Management considers its relations with our employees to be good. In addition, we supplement our consultants on certain engagements with independent contractors. We believe that the practice of retaining independent contractors on a per engagement basis provides us with significant flexibility in adjusting professional personnel levels in response to changes in demand for our services. 12 RISK FACTORS SOME OF THE INFORMATION IN THIS ANNUAL REPORT ON FORM 10-K CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE SUBSTANTIAL RISKS AND UNCERTAINTIES. YOU CAN IDENTIFY THESE STATEMENTS BY FORWARD-LOOKING WORDS SUCH AS "MAY," "WILL," "EXPECT," "ANTICIPATE," "BELIEVE," "ESTIMATE" AND "CONTINUE" OR SIMILAR WORDS. YOU SHOULD READ STATEMENTS THAT CONTAIN THESE WORDS CAREFULLY BECAUSE THEY: (1) DISCUSS OUR FUTURE EXPECTATIONS; (2) CONTAIN PROJECTIONS OF OUR FUTURE OPERATING RESULTS OR OF OUR FUTURE FINANCIAL CONDITION; OR (3) STATE OTHER "FORWARD-LOOKING" INFORMATION. WE BELIEVE IT IS IMPORTANT TO COMMUNICATE OUR EXPECTATIONS TO OUR INVESTORS. THERE MAY BE EVENTS IN THE FUTURE, HOWEVER, THAT WE ARE NOT ACCURATELY ABLE TO PREDICT OR OVER WHICH WE HAVE NO CONTROL. THE RISK FACTORS LISTED IN THIS SECTION, AS WELL AS ANY CAUTIONARY LANGUAGE IN THIS ANNUAL REPORT ON FORM 10-K, PROVIDE EXAMPLES OF RISKS, UNCERTAINTIES AND EVENTS THAT MAY CAUSE OUR ACTUAL RESULTS TO DIFFER MATERIALLY FROM THE EXPECTATIONS WE DESCRIBE IN OUR FORWARD-LOOKING STATEMENTS. YOU SHOULD BE AWARE THAT THE OCCURRENCE OF ANY OF THE EVENTS DESCRIBED IN THESE RISK FACTORS AND ELSEWHERE IN THIS ANNUAL REPORT ON FORM 10-K COULD HAVE A MATERIAL ADVERSE EFFECT ON OUR BUSINESS, FINANCIAL CONDITION AND OPERATING RESULTS AND THAT UPON THE OCCURRENCE OF ANY OF THESE EVENTS, THE TRADING PRICE OF OUR COMMON STOCK COULD DECLINE. RISKS ASSOCIATED WITH OUR ACQUISITION STRATEGY A significant part of our growth strategy is to acquire other companies that complement our lines of business or that broaden our geographic presence. During fiscal 1998, we purchased ten companies in five separate transactions. We expect to continue to acquire companies as an element of our growth strategy. Acquisitions involve certain risks that could cause our actual growth or operating results to differ from our expectations or the expectations of security analysts. For example: - We may not be able to identify suitable acquisition candidates or to acquire additional companies on favorable terms; - We compete with others to acquire companies. We believe that this competition will increase and may result in decreased availability 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 fail to successfully integrate or manage these acquired companies due to differences in business backgrounds or corporate cultures; - These acquired companies may not perform as we expect; - We may find it difficult to provide a consistent quality of service across our geographically diverse operations; and - 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. In addition, our acquisition strategy may divert management's attention away from our primary service offerings, result in the loss of key clients or personnel and expose us to unanticipated liabilities. 13 Finally, acquired companies that derive a significant portion of their revenues from the Federal government and that do not follow the same cost accounting policies and billing procedures as we do may be subject to larger cost disallowances for greater periods than we are. 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. FLUCTUATIONS IN OUR QUARTERLY OPERATING RESULTS Our quarterly revenues, expenses and operating results may fluctuate significantly because of a number of factors, including: - The seasonality of the spending cycle of our public sector clients, notably the Federal government; - Employee hiring and utilization rates; - The number and significance of client engagements commenced and completed during a quarter; - Delays incurred in connection with an engagement; - The ability of our clients to terminate engagements without penalties; - The size and scope of engagements; - The timing and size of the return on investment capital; and - General economic and political conditions. Variations in any of these factors could cause significant fluctuations in our operating results from quarter to quarter and could result in net losses. POTENTIAL VOLATILITY OF OUR STOCK PRICE The trading price of our common stock has fluctuated widely. In addition, in recent years the stock market has experienced extreme price and volume fluctuations. 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 operating results; - Changes in environmental legislation; - Changes in investors' and analysts' perception of the business risks and conditions of our business; - Broader market fluctuations; and - General economic or political conditions. MANAGEMENT OF GROWTH We are growing rapidly. Our 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 operational, financial and human resource 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 14 management to manage our growth effectively or the inability of our employees to achieve anticipated performance or utilization levels, could have a material adverse effect on our business. RELIANCE ON KEY PERSONNEL AND QUALIFIED PROFESSIONALS 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 the principal stockholders of each of the companies we have acquired, we generally do not have non-compete or employment agreements with key employees who were not equity holders of these companies. We do not maintain key-man life insurance policies on any of our executive officers or senior managers. 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. DEPENDENCE UPON EXISTING LAWS AND REGULATIONS A significant amount of our resource management business is generated either directly or indirectly as a result of existing Federal and state governmental laws, regulations and programs. Any changes in these laws or regulations that reduce funding or affect the sponsorship of these programs could reduce the demand for our services and could have a material adverse effect on our business. CONCENTRATION OF REVENUES Agencies of the Federal government are among our most significant clients. During fiscal 1998, approximately 46.8% of our net revenue was derived from three federal agencies as follows: 26.2% of our net revenue was derived from the Department of Defense (DOD), 17.1% from the Environmental Protection Agency (EPA), and 3.5% from the Department of Energy (DOE). Some of our contracts with Federal government agencies require annual funding approval and may be terminated at their discretion. A reduction in spending by Federal government agencies could limit the continued funding of our existing contracts with them and could limit our ability to obtain additional contracts. These limitations, if significant, could have a material adverse effect on our business. Additionally the failure of clients to pay significant amounts due us for our services could adversely affect our business. For example, we recently received notification from a federal government agency that we are entitled to payments in excess of our billings. However, the agency involved must obtain specific funding approval for amounts owed to us and there can be no assurance this funding approval will be obtained. RISKS ASSOCIATED WITH GOVERNMENTAL AUDITS Our contracts with the Federal government and other governmental agencies are subject to audit. Most of these audits are conducted by the Defense Contract Audit Agency (DCAA), which reviews our overhead rates, operating systems and cost proposals. The DCAA may disallow costs if it determines that we accounted for these costs incorrectly or in a manner inconsistent with Cost Accounting Standards. A disallowance of costs by the DCAA, or other governmental auditors, could have a material adverse effect on our business. In September 1995, we acquired PRC Environmental Management, Inc. (EMI). EMI also contracts with Federal government agencies and such contracts are also subject to the same governmental audits. The DCAA has completed audits of EMI's contracts for the fiscal years 1987 15 through 1995. As a result of these audits and our negotiations with the DCAA, the DCAA disallowed approximately $2.9 million in costs. FIXED PRICE CONTRACTS We enter into various contracts with our clients, including fixed-price contracts. In fiscal 1998, approximately 27.3% of our net revenue was derived from fixed-price contracts. Fixed-price contracts protect clients and expose us to a number of risks. These risks include underestimation of costs, problems with new technologies, unforeseen costs or difficulties, delays beyond our control and economic and other changes that may occur during the contract period. If we incur losses under fixed-price contracts it could have a material adverse effect on our business. DEPENDENCE ON SUBCONTRACTORS 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 fiscal 1998, subcontractor costs comprised 22.3% of our gross revenue. The absence of qualified subcontractors with whom we have a satisfactory relationship could adversely affect the quality of our service and our ability to perform under some of our contracts. SIGNIFICANT COMPETITION We provide specialized management consulting and technical services to a broad range of public and private 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 national firms which have greater financial and marketing resources than we do. We focus primarily on the resource management, infrastructure and communications business areas. We provide services to our clients which include Federal, state and local agencies, and organizations in the private sector. We compete for projects and engagements with a number of competitors which can vary from 10 to 100 firms. Historically, clients have chosen among competing firms based on the quality and timeliness of the firm's service. We believe, however, that price has become an increasingly important factor. We believe that our principal competitors include, in alphabetical order, Black & Veatch LLP; Brown & Caldwell; Castle Tower Corporation; Camp, Dresser & McKee; CH2M Hill Companies Ltd.; Dames & Moore Group; EA Engineering, Science & Technology, Inc.; Earth Tech, Inc.; ICF Kaiser International, Inc.; IT Group Inc.; Mastec, Inc.; Montgomery Watson; OSP Consultants, Inc.; Roy F. Weston, Inc.; and URS Greiner Corporation. POTENTIAL LIABILITY AND INSURANCE Our services involve significant risks of professional and other liabilities which may substantially exceed the fees we derive from our services. Our business activities could expose us to potential liability under various environmental laws such as the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA). In addition, we sometimes contractually assume liability under indemnification agreements. We cannot predict the magnitude of such potential liabilities. We currently maintain comprehensive general liability, umbrella and professional liability insurance policies. We believe that our insurance policies are adequate for our business operations. These policies are "claims made" policies. Thus, only claims made during the term of the policy are covered. If we terminate our policies and do not obtain retroactive coverage, we would be uninsured for claims made after termination even if these claims are based on events or acts that occurred during 16 the term of the policy. Our insurance may not protect us against liability because our policies typically have various exclusions and retentions. In addition, if we expand into new markets, we may not be able to obtain insurance coverage for such activities or, if insurance is obtained, the dollar amount of any liabilities incurred could exceed our insurance coverage. A partially or completely uninsured claim, if successful and of significant magnitude, could have a material adverse affect on our business. CONFLICTS OF INTEREST 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 contracts resulting from or relating to certain work we have performed for the government. In addition, services performed for a private 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. RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS In fiscal 1998, approximately 3.2% of our net revenue was derived from the international marketplace. 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. If our international revenue increases, our exposure to foreign currency fluctuations will also increase. We have entered into forward exchange contracts to address foreign currency fluctuations. YEAR 2000 We are working to resolve the potential impact of the year 2000 on our business operations and the ability of our computerized information systems to accurately process information that may be date-sensitive. Any of our programs that recognize a date using "00" as the year 1900 rather than the year 2000 could result in errors or system failures. We utilize a number of computer programs across our entire operation. The primary information technology systems we utilize are the accounting and financial and human resource information management systems. We began our risk assessment in 1995. Since that time we have procured and implemented certain accounting and financial reporting systems as well as contract administration and billing systems that have been certified as year 2000 compliant by our vendors. Currently, approximately 72% of our gross revenue is recognized on these year 2000 compliant systems. We believe that our financial and accounting and human resource management information systems will be year 2000 compliant in a timely manner and will not be materially impacted by the year 2000. We may fail, however, in updating our various systems to be year 2000 compliant in a timely manner. We have extensive business with the Federal government. Should the Federal government, especially the Department of Defense (DOD), experience significant business interruptions relating to non-year 2000 compliance, our business could be materially impacted. To the extent that other third parties which we rely upon, such as banking institutions, clients and vendors, are unable to address their year 2000 issues in a timely manner, our business could be materially impacted. We believe that the worst case scenario relating to the year 2000 would be an extensive period of time in which the Federal government and other third parties could not process payments promptly, in addition to our financial institutions not being able to supply us with our working capital needs. 17 Additional risks associated with non-year 2000 compliance include: - Our inability to invoice and process payments; - Our inability to produce accurate and timely financials; - The impact on our profitability; and - Our potential liability to third parties for not meeting contracted deliverables. IMPACT OF ANTI-TAKEOVER PROVISIONS ON OUR STOCK PRICE Our certificate of incorporation and by-laws and the Delaware General Corporation Law include provisions that may be deemed to have anti-takeover effects. These anti-takeover effects could delay or prevent a takeover attempt that you or our other stockholders might consider in your or their best interests. In addition, our board of directors is authorized to issue, without obtaining stockholder approval, up to 2,000,000 shares of preferred stock and to determine the price, rights, preferences and privileges of such shares without any further stockholder action. The existence of this "blank-check" preferred stock could make more difficult or discourage an attempt to obtain control of us by means of a tender offer, merger, proxy contest or otherwise. In the future, we may adopt other measures that may have the effect of delaying, deferring or preventing an unsolicited takeover, even if such a change in control were at a premium price or favored by a majority of unaffiliated stockholders. Certain of these measures may be adopted without any further vote or action by the stockholders. 18 ITEM 2. PROPERTIES. Our corporate headquarters facilities are located in Pasadena, California. These facilities contain approximately 25,000 square feet of office space, and are subject to leases which expire beyond the year 2001. We lease office space in approximately 112 locations in the United States. We also rent some additional office space on a month-to-month basis. We believe that our existing facilities are adequate to meet current requirements and that suitable additional or substitute space will be available as needed to accommodate any expansion of operations. 19 PART II ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS. OVERVIEW Tetra Tech, Inc. is a leading provider of specialized management consulting and technical services in three principal business areas: resource management, infrastructure and communications. As a specialized management consultant, we assist our clients in defining problems and developing innovative and cost-effective solutions. Our management consulting services are complemented by our technical services. These technical services, which implement solutions, include research and development, applied science, engineering and architectural design, construction management, and operations and maintenance. Our clients include a diverse base of public and private organizations located in the United States and internationally. Since our initial public offering in December 1991, we have increased the size and scope of our business and have expanded our service offerings through a series of strategic acquisitions and internal growth. From fiscal 1991 through fiscal 1998, we generated a net revenue compounded annual growth rate of approximately 34.2%, and achieved a net income compounded annual growth rate of approximately 36.4%. We derive our gross revenues from fees from professional services. Our services are billed under various types of contracts with our clients, including: - Fixed-price; - Fixed-rate time and materials; - Cost-reimbursement plus fixed fee; and - Cost-reimbursement plus fixed and award fee. In the course of providing our services, we routinely subcontract services. These subcontractor costs are passed through to clients and, in accordance with industry practice, are included in our gross revenue. Because subcontractor services can change significantly from project to project, we believe net revenue, which is gross revenue less the cost of subcontractor services, is a more appropriate measure of our performance. Our cost of net revenue includes professional compensation and certain direct and indirect overhead costs such as rents, utilities and travel. Professional compensation represents the majority of these costs. Our selling, general and administrative (SG&A) expenses are comprised primarily of our corporate headquarters' costs related to the executive offices, corporate accounting, information technology, marketing, and bid and proposal costs. These costs are generally unrelated to specific client projects. In addition, we include amortization of certain intangible assets resulting from acquisitions in SG&A expenses. 20 We provide services to a diverse base of Federal, state and local government agencies, and private and international clients. The following table presents, for the periods indicated, the approximate percentage of our net revenue attributable to these client sectors: PERCENTAGE OF NET REVENUE ------------------------------------- CLIENT FISCAL 1996 FISCAL 1997 FISCAL 1998 - --------------------------------------------- ----------- ----------- ----------- Federal government........................... 61.7% 52.3% 48.7% State and local government................... 16.6 14.8 12.7 Private...................................... 20.1 29.2 35.4 International................................ 1.6 3.7 3.2 ----- ----- ----- Total........................................ 100.0% 100.0% 100.0% ----- ----- ----- ----- ----- ----- RECENT ACQUISITIONS As a part of our growth strategy, we expect to pursue complementary acquisitions to expand our geographical reach and the breadth and depth of our service offerings. During fiscal 1998, we purchased ten companies in the following five separate transactions: TETRA TECH NUS, INC. -- In December 1997, we acquired, through our wholly-owned subsidiary Tetra Tech NUS, Inc. (NUS), the assets of certain environmental services businesses of Brown & Root, Inc. and Halliburton Corporation. The purchase was valued at approximately $25.2 million. NUS is a nationwide firm providing consulting, engineering and design services for the environmental remediation of contaminated air, water and soil conditions. WHALEN/SENTREX LLC -- In March 1998, our wholly-owned subsidiary Whalen Service Corps Inc. agreed to participate in a partnership with Sentrex Cen-Comm and ANTEC Corporation. The partnership purchased certain assets from ANTEC Corporation for a price of approximately $0.6 million. The partnership, Whalen/Sentrex LLC, a Colorado-based firm, provides nationwide design, engineering, information management and construction services to support advanced communication system upgrades to the broadband information transport industries. C.D.C. ENGINEERING, INC. -- In March 1998, we acquired C.D.C. Engineering, Inc. (CDE). The purchase was valued at approximately $1.5 million. CDE, a California-based consulting and engineering firm, specializes in civil engineering, transportation engineering, structural engineering and land surveying. MCNAMEE, PORTER & SEELEY, INC. -- In July 1998, we acquired McNamee, Porter & Seeley, Inc. (MPS). The purchase was valued at approximately $14.2 million. MPS, a Michigan-based firm, provides engineering services throughout the Midwest with expertise in the areas of water, industrial wastewater and process controls. SENTREX GROUP OF COMPANIES -- In September 1998, we acquired, through our subsidiary, Tetra Tech Canada Ltd., six Canadian corporations that are collectively referred to as the Sentrex Group of Companies (SGOC). The purchase was valued at approximately $19.2 million. SGOC provides engineering and technical services to the cable television, telephony and data networking industries. As a result of the SGOC acquisition, we now own 100% of Whalen/Sentrex LLC. 21 RESULTS OF OPERATIONS The following table sets forth, for the periods indicated, certain operating information as a percentage of net revenue: PERCENTAGE RELATIONSHIP TO NET REVENUE ------------------------------------- FISCAL YEAR ENDED ------------------------------------- SEPT. 29, SEPT. 28, OCT. 4, 1996 1997 1998 ----------- ----------- ----------- Net revenue......................................... 100.0% 100.0% 100.0% Cost of net revenue................................. 75.8 73.9 75.2 ----- ----- ----- Gross profit........................................ 24.2 26.1 24.8 Selling, general and administrative expenses........ 13.2 13.2 11.4 ----- ----- ----- Income from operations.............................. 11.0 12.9 13.4 Net interest income (expense).......................

Net revenue increased $106.8 million, or 56.0%, to $297.6 million in fiscal 1998 from $190.8 million in fiscal 1997. All four client sectors continued to show net revenue increases in actual dollars. These increases were attributable to increases in our existing Federal government contracts, the introduction of new lines of service in our communications business and to companies acquired in fiscal 1998. As a percentage of net revenue, increases were realized in the private sector. Net revenue from the companies acquired in fiscal 1998 totaled $72.0 million. Excluding the net revenue from these companies, we realized 18.2% growth in our net revenue. Gross revenue increased $136.2 million, or 55.2%, to $382.9 million in fiscal 1998 from $246.8 million in fiscal 1997. In fiscal 1998, subcontractor costs comprised 22.3% of gross revenue compared to 22.7% for fiscal 1997. COST OF NET REVENUE. Cost of net revenue increased $82.9 million, or 58.8%, to $223.9 million in fiscal 1998 from $141.0 million in fiscal 1997. As a percentage of net revenue, cost of net revenue increased from 73.9% in fiscal 1997 to 75.2% in fiscal 1998. This increase was primarily attributable to higher costs of Federal government contracts, as well as costs incurred in connection with the additional net revenue from the acquired companies. Professional compensation, the largest component of our cost of net revenue, rose as the number of our employees increased by 1,400 or 61.9%, to 3,662 in fiscal 1998 from 2,262 in fiscal 1997. Excluding the employees provided from acquired companies, our number of employees increased by 265, or 11.7%. Gross profit increased $24.0 million, or 48.1%, to $73.7 million in fiscal 1998 from $49.8 million in fiscal 1997. However, as a percentage of net revenue, gross profit decreased from 26.1% in fiscal 1997 to 24.8% in fiscal 1998, primarily due to a change in the relative mix of our Federal government contracts. SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. SG&A expenses increased $8.7 million, or 34.7%, to $33.9 million in fiscal 1998 from $25.2 million in fiscal 1997. This increase was primarily attributable to additional headquarters' costs associated with centralizing corporate functions as well as additional amortization expense relating to acquired companies. As a percentage of net revenue, SG&A expenses decreased from 13.2% in fiscal 1997 to 11.4% in fiscal 1998 due to operating efficiencies. The 22 amortization expenses related to acquisitions increased $1.4 million, or 89.1%, to $3.0 million in fiscal 1998 from $1.6 million in fiscal 1997. NET INTEREST EXPENSE. Net interest expense increased from less than $0.1 million to $1.9 million from fiscal 1997 to fiscal 1998. This increase was primarily attributable to the financing and working capital needs of certain acquisitions. INCOME TAX EXPENSE. Income tax expense increased $5.6 million, or 54.2% to $15.9 million in fiscal 1998 from $10.3 million in fiscal 1997. This increase was due to higher income before income taxes and an increase in our effective tax rate from 42.0% in fiscal 1997 to 43.6% in fiscal 1998. This increase was primarily attributable to amortization amounts which were not tax deductible. FISCAL 1997 COMPARED TO FISCAL 1996 NET REVENUE. Net revenue increased $29.8 million, or 18.5%, to $190.8 million in fiscal 1997 from $161.0 million in fiscal 1996. The increase in net revenue was primarily attributable to revenue associated with companies acquired in fiscal 1997 which totaled $24.6 million. Despite the weakened condition of the environmental industry, which was impacted by the decrease in Federal government activity, we attained a 3.2% growth in our net revenue, excluding revenue related to acquired companies. Gross revenue increased $26.7 million, or 12.1%, to $246.8 million in fiscal 1997 from $220.1 million in fiscal 1996. In fiscal 1997, subcontractor costs were 22.7% of gross revenue, compared to 26.8% for fiscal 1996. This decrease was due to the nature of the projects undertaken. COST OF NET REVENUE. Cost of net revenue increased $18.9 million, or 15.5%, to $141.0 million in fiscal 1997 from $122.1 million in fiscal 1996. This increase was primarily attributable to costs incurred in connection with the additional net revenue from the acquired companies. As a percentage of net revenue, cost of net revenue decreased from 75.8% in fiscal 1996 to 73.9% in fiscal 1997. Professional compensation, the largest component of our cost of net revenue, rose as the number of employees increased by 363, or 19.1%, to 2,262 in fiscal 1997 from 1,899 in fiscal 1996. Excluding the employees provided from acquired companies, our number of employees remained relatively flat. Gross profit increased $10.8 million, or 27.8%, to $49.8 million in fiscal 1997 from $39.0 million in fiscal 1996, primarily due to efficiencies in operations, acquisitions and higher profit margins realized in the acquired businesses in the communications industry. SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. SG&A expenses increased $4.0 million, or 18.6%, to $25.2 million in fiscal 1997 from $21.2 million in fiscal 1996. However, as a percentage of net revenue, SG&A expenses remained flat at 13.2% for fiscal 1997. The amortization of intangible assets relating to acquisitions increased $0.4 million, or 29.8%, to $1.6 million in fiscal 1997 from $1.2 million in fiscal 1996. NET INTEREST EXPENSE. Net interest expense decreased $0.8 million to less than $0.1 million in fiscal 1997 due to the reduction of the average outstanding borrowings from fiscal 1996 to fiscal 1997. INCOME TAX EXPENSE. Income tax expense increased $3.4 million, or 50.6%, to $10.3 million in fiscal 1997 from $6.9 million in fiscal 1996. Our effective tax rate increased from 40.4% in fiscal 1996 to 42.0% in fiscal 1997. This increase was primarily attributable to amortization amounts which were not tax deductible. UNAUDITED QUARTERLY OPERATING RESULTS The following tables set forth certain unaudited quarterly operating results for each of our last three fiscal years ended September 29, 1996, September 28, 1997 and October 4, 1998. This data is also expressed as a percentage of net revenue for the respective quarters. The information has been derived from unaudited consolidated financial statements that, in our opinion, reflect all adjustments, consisting 23 only of normal recurring adjustments, necessary for a fair presentation of such quarterly information.

Variations in any of these factors can cause significant variations in operating results from quarter to quarter and could result in losses. 24 LIQUIDITY AND CAPITAL RESOURCES As of October 4, 1998, our working capital was $77.0 million, an increase of $34.5 million from $42.5 million on September 28, 1997, of which cash and cash equivalents totaled $4.9 million. In fiscal 1998, we augmented cash used in operations with borrowings under our credit facility. In fiscal 1998, $6.6 million was used in operating activities and $41.3 million was used in investing activities, of which $37.8 million was related to business acquisitions. In fiscal 1997, we generated $1.1 million from operating activities and used $3.8 million in investing activities, of which $1.2 million was related to business acquisitions. The decreases in cash from operating activities in fiscal 1998 and fiscal 1997 primarily resulted from the payment of liabilities assumed in connection with fiscal 1998 acquisitions of approximately $6.4 million as well as the acquisitions of Whalen & Company, Inc. in fiscal 1997 and McNamee, Porter & Seeley, Inc. in fiscal 1998. In these acquisitions we agreed that we would not acquire the accounts receivable. As a result, we experienced a lag in cash flow to fund the business' operations. As an ongoing effort, we attempt to increase our efficiencies in the timing of billings and the collection of receivables. Our capital expenditures during fiscal years 1996, 1997, and 1998 were approximately $2.4 million, $2.6 million and $3.5 million, respectively. The expenditures were primarily for computer equipment, leasehold improvements and office expansion. We have a credit agreement with a bank (the "Credit Agreement") which, as of October 4, 1998, provided us with a revolving credit facility (the "Facility") of $70.0 million. The Credit Agreement provides for mandatory reductions of $5.0 million on December 15, 1998 and December 15, 1999. We amended the Credit Agreement during fiscal 1998 in order to accommodate the fiscal 1998 acquisitions as well as to position ourselves to pursue future acquisitions. The Facility matures on December 15, 2000 or earlier at our discretion upon payment in full of loans and other obligations. Throughout fiscal 1998, maximum borrowings under the Facility were $49.0 million. At October 4, 1998, borrowings and standby letters of credit totaled $47.0 million and $2.2 million, respectively. We expect that internally generated funds, our existing cash balances, proceeds from this offering and availability under the Credit Agreement will be sufficient to meet our capital requirements through the end of fiscal 1999. We continuously evaluate the marketplace for strategic acquisition opportunities. Once an opportunity is identified, we examine the effect an acquisition may have on the business environment, as well as on our results of operations. We proceed with an acquisition if we determine that the acquisition is anticipated to have an accretive effect on future operations. However, as successful integration and implementation are essential to achieve favorable results, no assurances can be given that all acquisitions will provide accretive results. Our strategy is to position ourselves to address existing and emerging markets. We view acquisitions as a key component of our growth strategy, and we intend to use both cash and our securities, as we deem appropriate, to fund such acquisitions. We believe our operations have not been and, in the foreseeable future, we do not expect to be materially adversely affected by inflation or changing prices. RECENTLY ISSUED FINANCIAL STANDARDS In February 1997, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standard (SFAS) No. 128, EARNINGS PER SHARE, which we adopted in fiscal year 1998. The Statement replaces the presentation of primary EPS with a presentation of basic EPS, which excludes dilution and is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for the period. The Statement also requires the dual presentation of basic and diluted EPS on the face of the income statement for all companies with complex capital structures and requires a reconciliation of the numerator and denominator of the basic EPS computation to the numerator and denominator of the diluted EPS computation. Diluted EPS is computed similarly to fully diluted EPS pursuant to APB Opinion No. 15. EPS has been retroactively restated to reflect the requirements of SFAS No. 128. 25 In June 1997, the FASB issued SFAS No. 130, REPORTING COMPREHENSIVE INCOME. The Statement is effective for fiscal years beginning after December 15, 1997. The Statement establishes standards for reporting and display of comprehensive income and its components (revenues, expenses, gains and losses) in a full set of general-purpose financial statements. This Statement requires that all items that are required to be recognized under accounting standards as components of comprehensive income be reported in a financial statement that is displayed with the same prominence as other financial statements. We will adopt this Statement in fiscal year 1999. In June 1997, the FASB issued SFAS No. 131, DISCLOSURES ABOUT SEGMENTS OF AN ENTERPRISE AND RELATED INFORMATION. The Statement is effective for fiscal years beginning after December 15, 1997. The Statement establishes standards for the way that public business enterprises report information about operating segments as well as related disclosures about products and services, geographic areas, and major clients. The Statement also requires that a public business report descriptive information about the way that the operating segments were determined, the products and services provided by the operating segments, differences between the measurements used in reporting segment information and those used in the enterprise's general-purpose financial statements, and changes in the measurement of segment amounts from period to period. The Statement need not be applied to interim financial statements in the initial year of its application. We have not completed our analysis of the effect of SFAS No. 131 on our financial statements. We will adopt this Statement in fiscal year 1999. In June 1998, the FASB issued SFAS No. 133, ACCOUNTING FOR DERIVATIVES AND HEDGING ACTIVITIES. The Statement is effective for all fiscal quarters of fiscal years beginning after June 15, 1999. The Statement requires companies to recognize all derivative instruments on their balance sheet as either assets or liabilities measured at fair value. The Statement also specifies a new method of accounting for hedging transactions, prescribes the type of items and transactions that may be hedged, and specifies detailed criteria to be met to qualify for hedge accounting. We will adopt this Statement in fiscal year 2001. MARKET RISKS We currently utilize no material derivative financial instruments which expose us to significant market risk. We are exposed to cash flow risk due to interest rate fluctuations with respect to our long-term debt. At our option, we borrow on our Facility (a) at a base rate (the greater of the federal funds rate plus 0.50% or the bank's reference rate) or (b) at a eurodollar rate plus a margin which ranges from 0.75% to 1.25%. Borrowings at the base rate have no designated term and may be repaid without penalty anytime prior to the Facility's maturity date. Borrowings at a eurodollar rate have a term no less than 30 days and no greater than 90 days. Typically, at the end of such term, such borrowings may be rolled over at our discretion into either a borrowing at the base rate or a borrowing at a eurodollar rate with similar terms, not to exceed the maturity date of the Facility. The Facility matures on December 15, 2000 or earlier at our discretion upon payment in full of loans and other obligations. Accordingly, we classify total outstanding debt between current liabilities and long-term debt based on anticipated payments within and beyond one year's period of time. Without giving effect to the use of the proceeds we receive from the sale of our common stock in this offering, we presently anticipate repaying our long-term debt in the amounts of $14,065,000, $15,546,000 and $18,000,000 in fiscal 1999, 2000 and 2001, respectively. Assuming we pay our long-term debt in such amounts ratably throughout the year, and our average interest rate on our long-term debt increases or decreases by one percentage point, our interest expense would increase or decrease by $406,000, $258,000 and $90,000 in fiscal 1999, 2000 and 2001, respectively. However, there can be no assurance that we will, or will be able to, repay our long-term debt in the manner described. For example, we could incur additional debt under the Facility or our operating results could be worse than we expect. YEAR 2000 We are working to resolve the potential impact of the year 2000 on our business operations and the ability of our computerized information systems to accurately process information that may be date-sensitive. 26 Any of our programs that recognize a date using "00" as the year 1900 rather than the year 2000 could result in errors or system failures. We utilize a number of computer programs across our entire operation. The primary information technology (IT) systems we utilize are (1) the accounting and financial systems which include general ledger, accounts payable, accounts receivable, billing and collection, fixed assets, job cost accounting and payroll and (2) human resource information management systems. We do not believe we have a material amount of non-IT systems on which we rely. We have established both a year 2000 review committee and a year 2000 action team. The purpose of the review committee is to develop and communicate our year 2000 plan to achieve our year 2000 compliance mission. The purpose of the action team is to identify, remediate and implement plans to resolve our year 2000 related issues. Through the review committee and the action team, we are in the process of completing our full assessment of all issues relating to the year 2000. We have developed questionnaires regarding year 2000 readiness to be used internally and externally. We have completed our internal assessment and we are in the process of assessing the year 2000 issues of our clients and vendors. Based on the information collected to date, we do not believe that the cost of addressing our year 2000 issues will have a material adverse impact on our financial position. We plan to devote all resources required to resolve any significant year 2000 issues in a timely manner. STATE OF READINESS We began our risk assessment in 1995. Since that time we have procured and implemented certain accounting and financial reporting systems as well as contract administration and billing systems that have been certified as year 2000 compliant by our vendors. Currently, approximately 72% of our gross revenue is recognized on these year 2000 compliant systems. We have successfully converted seven of our 18 operating units to these year 2000 compliant systems. We are planning to convert four additional operating units by July 1999. The operating units that will not be converted to the systems currently in place are in the process of upgrading their existing systems to a year 2000 compliant version or will procure and implement year 2000 compliant software. In all cases, we believe that our financial and accounting systems will be year 2000 compliant in a timely manner and will not be materially impacted by the year 2000. We are currently installing a year 2000 compliant human resource information management system. Ten operating units including our corporate units will be supported by this system. The anticipated completion date is April 1999. We plan to convert the remaining operating units following April 1999. In all cases, we believe that our human resource management information systems will be year 2000 compliant in a timely manner and will not be materially impacted by the year 2000. We have expended or obligated approximately $2.6 million on the procurement of these systems, the conversion of data from legacy systems to these systems, and on the implementation and testing of these systems. We have extensive business with the Federal government. Should the Federal government, specifically the Department of Defense, experience significant business interuptions relating to non-year 2000 compliance, we could be materially impacted. To the extent that other third parties upon which we rely, such as banking institutions, clients and vendors, are unable to address their year 2000 issues in a timely manner, we could be materially impacted. We believe that the worst case scenario relating to the year 2000 would be an extensive period of time in which the Federal government and other third parties could not process payments promptly. 27 RISKS We believe the risks associated with non-year 2000 compliance include: - Our inability to invoice and process payments; - Our inability to produce accurate and timely financials; - The impact on our cash flow and working capital needs; - The impact on our profitability; and - Our potential liability to third parties for not meeting contracted deliverables. CONTINGENCY PLANS We currently do not have formal contingency plans for the failure of our financial and accounting systems. We have substantial experience in the conversion process from multiple legacy systems to our current year 2000 certified systems. We have an experienced and dedicated staff to perform the functions identified and are reasonably confident that the projected conversions will be accomplished as projected. We currently do not have formal contingency plans for the failure of our human resource information management system. Our implementation strategy is to install the system as simply as possible, with little customization. Our vendor supports our implementation strategy and has agreed to a financial penalty if the implementation is not achieved within three months, or by April 1999. If the implementation is not achieved by April 1999, we believe there will still be sufficient time to meet the year 2000 deadline. We maintain, as a matter of policy and practice, mitigation plans in the event of systems failure which include regular backup of historical information. 28 PART III ITEM 11.
