Incorporated by reference from registrant's definitive Proxy Statement for the Annual Meeting of Stockholders to be held May 14, 2003, which Proxy Statement will be filed not later than 120 days after the end of the fiscal year covered by this Annual Report on Form 10-K.

Forward Looking Information

        In response to the "safe harbor" provisions contained in the Private Securities Litigation Reform Act of 1995, Duratek, Inc. (the "Company") is including in this Annual Report on Form 10-K the following cautionary statements which are intended to identify certain important factors that could cause the Company's actual results to differ materially from those projected in forward-looking statements of the Company made by or on behalf of the Company. Many of these factors have been discussed in prior filings with the Securities and Exchange Commission.

        The Company's future operating results are largely dependent upon the Company's ability to manage its commercial waste processing operations, including obtaining commercial waste processing contracts and processing the waste under such contracts in a timely and cost-effective manner. In addition, the Company's future operating results are dependent upon the timing and awarding of contracts by the United States Department of Energy ("DOE") for the cleanup of other waste sites administered by it. The timing and award of such contracts by the DOE is directly related to the response of governmental authorities to public concerns over the treatment and disposal of radioactive, hazardous, mixed, and other wastes. The lessening of public concern in this area or other changes in the political environment could adversely affect the availability and timing of government funding for the cleanup of DOE and other sites containing radioactive and mixed wastes. Additionally, revenues from technical support services have in the past and continue to account for a substantial portion of the Company's revenues and loss of one or more technical support service contracts could adversely affect the Company's future operating results. Finally, a significant component of the Company's direct costs include the cost of disposal of materials in licensed landfills. The ability to reflect increased costs in pricing to customers, the availability of these licensed facilities, and any changes in the rate structures of such licensed facilities have the potential to affect the operating results of the Company.

        The Company's future operating results may fluctuate due to factors such as: the timing of new commercial waste processing contracts and duration of and amount of waste to be processed pursuant to those contracts; the acceptance and implementation of the Company's waste treatment technologies in the government and commercial sectors; the evaluation by the DOE and commercial customers of the Company's technologies versus other competing technologies as well as conventional storage and disposal alternatives; the timing of new government waste processing projects, including those pursued jointly with others; the duration of such projects; and the timing of commercial nuclear power plant outages and other large technical support services projects at its customers' facilities.

        An element of the Company's growth strategy is to continue to pursue strategic acquisitions that expand and complement the Company's business, technologies, and service offerings. Under the Company's amended credit facility, which was completed in February 2003, the Company is permitted to enter into certain acquisitions, as defined in the credit agreement, subject to certain conditions. If the Company does complete an acquisition, the Company's future operating results may be affected by the costs and timing of completion and integration of such an acquisition.

Part I

Item 1. Business

Overview

        Duratek, Inc., together with its wholly owned subsidiaries (the "Company" or "Duratek"), provides safe, secure radioactive materials disposition and nuclear facility operations for commercial and government customers. The Company possesses the breadth of capabilities, technologies, assets, facilities, and qualified personnel necessary to provide a full array of radioactive material characterization, processing, transportation, accident containment and restoration services, and final disposition. The Company operates through its five licensed commercial facilities and on-site at customer premises. The Company's 1,000-plus project managers and technical personnel strive to implement the optimal technology to meet each customer's needs. The Company's capabilities include both proprietary and other proven technologies, including over 120 Company owned patents that can be used independently or in tandem to safely manage and process customers' radioactive material for long-term disposition.

        The Company's operations are organized into three primary segments: (i) federal services, (ii) commercial services, and (iii) commercial processing and disposal. The Company's federal services operations provide on-site waste processing and disposal services, off-site waste disposition, on-site management of nuclear facility operations, and on-site clean up (remedial action) services on large government projects for the United States Department of Energy ("DOE") and other governmental entities. The Company's services include program development, project management, nuclear facility operation, waste characterization, packaging and shipping of waste, selected technical services, and site cleanup.

        The Company's commercial services operations provide waste treatment and disposition services to a diverse group of commercial clients, including nuclear power utilities. These services include water processing, nuclear waste handling and treatment, transportation, licensing, packaging, heavy hauling, disposal, and nuclear facility decontamination and decommissioning ("D&D"). The Company operates treatment systems in nearly two dozen nuclear power plants, owns and operates various types of waste treatment equipment, and provides on-site waste management and clean up services at customers' facilities. The Company also provides technical support services to its clients which include project management, radiological engineering, radiation protection support, and environmental consulting. These services are provided by approximately 300 engineers, project managers, and technicians.

        The Company conducts its commercial processing and disposal operations at its three facilities in Tennessee and at two facilities in South Carolina. At these facilities, the Company uses multiple technologies to process customer waste for final disposition. The Company's ability to integrate its waste treatment technologies enables it to handle a diversity of waste streams in a cost-effective manner. The Company also operates a low-level radioactive waste disposal landfill site in Barnwell, South Carolina, which is one of the few facilities in the United States permitted to accept commercially generated low-level radioactive waste.

        In June 2000, the Company acquired the nuclear services business of Waste Management, Inc., which business is referred to as Waste Management Nuclear Services ("WMNS"). WMNS consisted of three operating segments: (i) the federal services division which provided radioactive waste handling, transportation, treatment, packaging, storage, disposal, site cleanup, and project management services primarily for the DOE and other federal agencies, (ii) the commercial services division which provided radioactive waste handling and treatment, transportation, licensing, packaging, disposition, and D&D services primarily to nuclear utilities, and (iii) the commercial disposal division which operated the

1

commercial low-level radioactive waste disposal facility in Barnwell, South Carolina. The results of the operations of WMNS are included in the Company's results from the date of the acquisition.

Information about the Company's Operating Segments

        Financial information about the Company's operating segments is in Part II, Item 8, Notes to Consolidated Financial Statements, in note 17, Segment Reporting and Business Concentrations.

Federal Services

        The Company's federal services operations provide on-site and off-site waste processing and disposal services, off-site waste disposition, on-site management of nuclear facility operations, and on-site clean up (remedial action) services on large government projects for the DOE and other governmental entities. The Company's services include program development, project management, nuclear facility operation, waste characterization, packaging and shipping of waste, selected technical services, and site cleanup. The Company has over 18 years of experience in designing, constructing, and operating low-level radioactive waste systems and facilities and providing site cleanup services for the DOE and other governmental entities. The Company occasionally teams with other companies to pool resources, submit proposals, and execute projects on behalf of the Company's clients. In 2002, the Company established joint ventures for a large project at Rocky Flats and a significant, long-term project for the DOE in Tennessee.

        The Company derives revenues in its federal services operations principally through subcontracts with a combination of DOE contractors and subcontractors. Revenues derived from the Company's federal services operations represented approximately 46.4%, 42.9%, and 32.5% of the Company's total revenues during 2002, 2001, and 2000, respectively. A significant portion of these revenues in 2002 were related to work performed for Bechtel Hanford, Inc., Bechtel Jacobs Company LLC, and Flour Hanford, Inc.

        The Company's federal services operations have managed waste facility operations, generator services, packaging and transportation, and related support activities at the Hanford Site, Oak Ridge Reservation, Idaho National Engineering and Environmental Laboratory, Brookhaven National Laboratory, Los Alamos National Laboratory, Rocky Flats, and other DOE sites since 1986.

        The following is a brief summary of a significant ongoing project and two new projects awarded in 2002 relating to the federal services operations:

        Hanford Waste Treatment Plant.    In 2000, Bechtel National Incorporated ("BNI") was awarded the DOE's Hanford Washington Waste Treatment Plant contract for the design, procurement, construction, and commissioning of the waste treatment plant. The contract has a ten-year duration and the Company has a significant role in this project. Revenues from this contract in 2002 were $6.6 million.

        BNI has contracted with the Company to provide the vitrification technology required for the project through engineering design and technology development contracts. As part of the engineering contract, the Company is developing the designs of both the High Level Waste ("HLW") and Low Active Waste ("LAW") melters as well as preparing to support the purchase and construction of these units. The integration of these activities into the contractor's overall schedule is presently underway. The Company is also working with BNI to advance the design, as well as provide the staffing, to meet the demanding engineering schedule that is expected from BNI over the next several years.

        Under the technology development contract with BNI, there are two key elements: first, continued use of the pilot DuraMelter™ in Columbia, Maryland and second, the contractual use of the DuraMelter™ 1200 located at the Catholic University of America's Vitreous State Laboratory. These two pilot scale melters, combined with several smaller scale systems, continue to be used by the project to demonstrate effectiveness of the technology on various simulated waste streams, test materials of construction for operability and longevity, and for their overall use as developmental platforms for project system design.

        DUF₆.    In August 2002, Uranium Disposition Services, LLC ("UDS") was awarded a contract by the DOE to design, build, and operate facilities in Paducah, Kentucky and Portsmouth, Ohio to convert the DOE's inventory of depleted uranium hexafluoride (DUF₆) for reuse or disposal. UDS will also be responsible for maintaining the depleted uranium and product inventories and transporting depleted uranium from Oak Ridge, Tennessee to the Portsmouth, Ohio plant for conversion. UDS is a limited liability company formed by the Company, Framatome ANP Inc., and Burns and Roe Enterprises Inc. The Company provides executive management, financial management, and other support functions for UDS and accounts for its investment under the equity method. The estimated total revenue of this nine-year contract is $558 million. The Company owns 26% of UDS and profits and losses of UDS are shared in accordance with the ownership percentages.

        The DOE has a large inventory of DUF₆ material with 56,000, 198,000 and 450,000 metric tons currently stored at its facilities in Tennessee, Ohio, and Kentucky, respectively. DUF₆ is a material byproduct of weapons production activities that occurred over the years at the three facilities. The conversion plants will convert the DUF₆ material to triuranium octoxide (U3O8), which will be suitable

3

for use or disposal. UDS will operate these facilities for five years after construction has been completed.

        Salt Waste Processing.    In October 2002, the DOE selected a team comprised of the Company, Parsons Infrastructure and Technology Group, Inc., and General Atomics to perform one of two contracts to complete the conceptual design for a new Salt Waste Processing Facility ("SWPF") at the Savannah River Site near Aiken, South Carolina. The SWPF will be a pre-treatment plant to remove cesium from the DOE's inventory of 38 million gallons of highly radioactive waste stored in 49 tanks at the Savannah River Site. Additional processing through a high-level vitrification facility and a chemical stabilization facility, which already exist at the Savannah River Site, will be the final stabilization for the treated waste. This one-year contract is the first phase of the project and has estimated total revenues of approximately $10 million, of which the Company's portion is 30%. This contract is a cost plus fixed fee contract. The conceptual design phase involves providing a design plan for the operation of the new plant to meet the DOE's expectations for safety, compliance, and performance. If the team which includes the Company is awarded the second phase of the project, which is expected to result in total revenues estimated to be in excess of $300 million, the Company will be responsible for supporting the detailed design, construction, and start-up of the new facility.

Commercial Services

        The Company's commercial services operations provide waste treatment and disposition services to a diverse group of commercial clients, including nuclear power utilities. These services include water processing, nuclear waste handling and treatment, transportation, licensing, packaging, heavy hauling, disposal, and nuclear facility D&D. The Company operates treatment systems in nearly two dozen nuclear power plants, owns and operates various types of waste treatment equipment, and provides on-site waste management and clean up services at customers' facilities. The Company also provides technical support services to its clients including project management, radiological engineering, radiation protection support, and environmental consulting. These services are provided by approximately 300 engineers, project managers, and technicians. Revenues derived from commercial services operations represented approximately 22.3%, 25.7%, and 28.3% of the Company's total revenues during 2002, 2001, and 2000, respectively. A significant portion of these revenues in 2002 were related to work performed for Bechtel Power Corp.

        The following is a brief summary of some of the types of services provided to the Company's commercial clients:

        THERMEX™ and ALPS liquid waste processing services.    The Company provides on-site liquid waste processing services to nuclear power generators throughout the United States. About 60 million gallons of water are successfully processed each year at 15 nuclear reactor plants. The Company is the largest provider of contracted liquid waste processing services to the commercial nuclear utility industry. A number of patented technologies, including unique and technically advanced membrane systems, are used to provide this service. These services are environmentally responsible in that they minimize radioactive waste generation, minimize or eliminate liquid releases to the environment, and allow recycling of wastewater.

        Transportation Services.    Through a wholly owned subsidiary, Hittman Transport Services, Inc. ("Hittman"), the Company maintains a fleet of tractors, trailers, and shipping containers for transporting radioactive waste and radioactively contaminated equipment for processing and disposal. All of Hittman's vehicles are constantly monitored via satellite to optimize waste pickup and delivery scheduling. Hittman maintains terminal locations around the country that are located within range of 90% of the commercial nuclear power plants in the United States. Hittman's services are complemented by a fleet of 60 casks, which is the largest fleet of casks in the United States. Casks are engineered shipping containers that allow safe transport of both liquid and solid radioactive waste. Ten

4

of these casks are United States Nuclear Regulatory Commission ("NRC") licensed type "B" shipping casks which provide a unique capability to handle virtually any type of radioactive material. The Company's cask fleet is unique in that it contains the largest volume type "B" shipping cask, the 10-160B, which has also been licensed by the NRC to transport transuranic waste for the DOE.

        Site Decontamination and Decommissioning.    The Company has performed D&D services at over 60 facilities worldwide, including work at two nuclear power plants that have been completely decommissioned to NRC requirements. The Company has performed D&D services at the following commercial nuclear power plants: Fort St. Vrain Nuclear Generating Station, Humboldt Bay Power Plant Unit 3, Shoreham Nuclear Power Station, Rancho Seco Nuclear Station, and Trojan Nuclear Power Plant. The Company is currently performing D&D services under contracts for Connecticut Yankee's Haddam Nuclear Power Station, Consumers Energy Big Rock Point Nuclear Power Plant, Maine Yankee Atomic Power Company, and Yankee Rowe Nuclear Power Plant. In addition, D&D services are being provided for two university research reactors and a number of other commercial facilities. D&D services provided by the Company include site radiological surveys, instrument provision, waste characterization, decommissioning planning, remediation, health physics support, total waste management services, waste processing, and final surveys. The Company has technical personnel who have developed project techniques accepted by the NRC, radioactive material licenses, programs, procedures, equipment, and instrumentation to handle projects that range from small hot cells to large nuclear power stations. In addition, through its transportation and commercial waste processing operations, the Company offers its customers an integrated and comprehensive solution to their site D&D problems.

        Radiological Engineering Services.    The Company's technical personnel provide commercial and government customers with a variety of radiological engineering services, including development of health physics and emergency preparedness programs, MORT analysis, licensing, procurement, and training in radiological protection and radioactive waste transportation. Most of the Company's senior technical personnel that provide radiological engineering services are fully certified and have had extensive experience at operating nuclear power plants regulated by the NRC.

        Environmental Consulting Services.    The Company provides environmental consulting services to clients in the areas of environmental remediation, facility decommissioning, Occupational Safety and Health Act ("OSHA") and United States Environmental Protection Agency ("EPA") compliance audits, site characterization, licensing and permitting, and air quality and emission studies. The Company either supplies professionals and technical personnel to supplement client staffs or assumes responsibility for entire projects. Included among the Company's available personnel for such environmental consulting projects are chemical, civil, and environmental engineers, certified health physicists, chemists, toxicologists, safety and health experts, regulatory compliance specialists, remediation experts, radiological control technicians, hazardous material technicians, and decontamination experts.

Commercial Processing and Disposal

        The Company conducts its commercial processing and disposal operations at its three Tennessee locations: the Bear Creek Operations Facility in Oak Ridge, the Company's facility in Memphis, and the Gallaher Road Operations Facility in Kingston. The Company also operates two facilities in Barnwell, South Carolina: the Duratek Consolidation & Services Facility ("DCSF") and the Barnwell Low-Level Radioactive Waste Management Disposal Facility. The Bear Creek Operations Facility is the largest commercial waste processing facility for low-level radioactive waste in the United States and has the capability to handle over 60 million pounds of radioactive waste per year. The Company uses a combination of treatment technologies to process the waste to achieve significant volume and mass reduction before sending it for disposal. Accordingly, the Company believes its customers benefit from

5

significant cost savings through the reduction of disposal cost by first confirming the presence of radioactive material and then minimizing the volume and mass of waste. The technologies used at the Tennessee based processing operations include incineration, compaction, metal decontamination and recycling, and Green is Clean. The Memphis, Tennessee facility is equipped to receive, decontaminate, and cut large nuclear power plant components, reducing their disposal cost. In 2003, the Company has decided to include the results of the Memphis operations in its commercial services operations as this operation will support the transportation and technical support services. The DCSF was originally chartered to support the Department of Defense ("DOD") in preparation of materials for disposal. Continuing missions have supported military equipment decontamination and parts retrieval/recycling. The DCSF continues to provide flexible, rapid response capacities to national as well as international DOD projects, conflicts, and missions. The Company's ability to integrate its waste treatment technologies enables it to handle diverse forms of waste streams in a cost-effective manner.

        In the WMNS transaction, the Company acquired the operating rights to a commercial low-level radioactive waste disposal landfill site in Barnwell, South Carolina. This waste disposal landfill site is one of the few facilities in the United States permitted to accept commercially generated low-level radioactive waste. The site is owned by the State of South Carolina and leased to the Company under a long-term lease. The Company operates the site under a license granted by the State of South Carolina. The Barnwell facility pursues the disposal market for large nuclear components not suitable for volume reduction and ion exchange resins and wastes that are generated by nuclear power plants, hospitals, research laboratories, and industrial facilities. Effective July 1, 2000, the South Carolina General Assembly passed the Atlantic Interstate Low-Level Radioactive Waste Compact Implementation Act (the "Act"). The provisions of the Act extensively govern the relationship between the State of South Carolina and operators of facilities for the disposal of low-level radioactive waste ("LLRW") in a comprehensive economic regulatory program. The Act establishes a schedule of declining annual maximum volumes of LLRW from generators within and outside of the compact to be disposed of at the Barnwell facility in South Carolina. The maximum annual volume declines from 160,000 cubic feet to 35,000 cubic feet over an eight-year period. After this eight-year period, the site will remain open for waste from the three Atlantic Compact states only. Under the Act, the Company is reimbursed for allowable costs identified by the South Carolina Public Service Commission and incurred by the Company plus an operating margin of 29% on certain of those allowable costs. The results from July 1, 2000 forward are based on the economic regulation imposed by the Act.

        Revenues derived from the commercial processing and disposal operations are from the processing and treatment of customer waste streams, from the DCSF facility, and from the operations of the Barnwell waste disposal landfill site. Customers of the Company's commercial processing and disposal operations include electric utilities, government agencies, industrial facilities, laboratories, hospitals, and others. Revenues derived from the Company's commercial processing and disposal operations represented approximately 31.3%, 31.4%, and 39.2%, of the Company's total revenues in 2002, 2001, and 2000, respectively. A significant portion of these revenues in 2002 were related to work performed for Bechtel Power Corp.

        The Company has developed or acquired several waste treatment technologies for use on a variety of radioactive, mixed, and other waste streams. The following is a brief summary of the waste treatment technologies that are being utilized by the Company in its commercial processing and disposal operations:

        Incineration.    Incineration is the most cost-effective treatment for most dry active waste and is the preferred waste treatment technology of many of the Company's customers for non-hazardous solid waste, waste oils, and other waste liquids. The Company's two incinerators at its Bear Creek Operations Facility are the only two licensed commercial low-level radioactive waste incinerators in the United States. The Company's incinerators are capable of processing solid waste at up to 1,600 pounds per hour and up to 30 gallons of radioactive, non-hazardous waste oils simultaneously.

6

        Compaction.    Achieving maximum density is critical to cost-effective radioactive waste disposal at most burial sites. The Company's UltraCompactor™ at its Bear Creek Operations Facility is the nation's largest compactor available for low-level radioactive waste, capable of compacting both drums and boxes (up to 38 cubic feet) with the force of 10 million pounds. The UltraCompactor™ has a capacity of 70,000 cubic feet per month. Average volume reduction using the Company's compaction technology is approximately six times for dry active waste and eight times for asbestos. Typically, the waste processed utilizing this technology is dry active waste and includes paper, plastic, asbestos, metals, woods, and filters.

        Metal Decontamination and Recycling.    The Company's metals processing program at its Bear Creek Operations Facility provides a cost-effective solution for radioactively contaminated metals by using a combination of surveying, compaction, decontamination, and melting. The Company examines the metal and sorts it for processing based on its contamination level to achieve the most cost-effective process for final disposition. If it is cost-effective, the Company will volume reduce the metal using its UltraCompactor™ and send it to an appropriate low-level radioactive burial site. The Company's specialized decontamination equipment allows metal to be successfully decontaminated for landfill disposal. For metals that cannot be decontaminated, the Company may utilize its metal melting technology. The Company's 20 ton, 7,200 kW electric induction furnace operates exclusively for melting and beneficially reusing radioactive metal. All of the metal processed through the metal melt furnace is beneficially reused in the form of shield blocks and provided to various high-energy physics projects throughout the United States. These radioactive shield blocks are not released to the public and they are not released for commercial scrap metal recycling. The beneficial reuse of radioactive metal eliminates the liability for the original waste generator and saves resources by using radioactive metal instead of new metal that will eventually become radioactive.

        Green is Clean.    The Company's Green is Clean ("GIC") program is a multi-step, bulk assay and release process that is fully licensed and permitted for operation in Tennessee. The GIC process relies on advanced assay technology to determine the presence of radioactive materials in potentially "clean" waste generated within a radiologically controlled area or licensed facility. The GIC process greatly reduces the amount of radioactive waste burial by segregating "clean" solid waste from "radioactive" waste. Thus, radioactive burial space is saved for radioactive waste and customer costs for radiological operations and decommissioning projects are reduced. The Company also has a mobile version of the GIC bulk assay equipment that can be operated at a customer's site.

Sales and Marketing Strategy

        The Company's product and service offerings provide cost-effective waste management solutions for commercial and DOE low-level radioactive waste generators. The marketing and business development organization is centralized while direct sales is decentralized to more closely align activities with the specific operating segments of the Company. This approach has strengthened the Company's competitive position when pursuing commercial and DOE service contracts and waste remediation projects.

Environmental Matters

Environmental Laws and Regulations Creating a Demand for the Company's Waste Treatment Technologies

        Various environmental protection laws have been enacted and amended during recent decades in response to public concern over the environment. The operations of the Company's customers are subject to these evolving laws and the implementing regulations. The Company believes that the obligations to comply with the requirements of the following laws contribute to the demand for its services.

7

        The Atomic Energy Act of 1954 ("AEA") and the Energy Reorganization Act of 1974 (the "ERA") authorize the NRC to regulate the receipt, possession, use, and transfer of radioactive materials, including "source material," "special nuclear material," and "byproduct material." Pursuant to its authority under the AEA, the NRC has adopted regulations that address the management, treatment, and disposal of low-level radioactive waste, and that require the licensing of low-level radioactive waste disposal sites by NRC or NRC Agreement States.

        The processing, storage, and disposal of high-level nuclear waste are subject to the requirements of the Nuclear Waste Policy Act, as amended by the Nuclear Waste Policy Act Amendments. These statutes regulate the disposal of high-level nuclear waste by establishing procedures and schedules for siting geologic repositories for such waste. The NRC has issued regulations that address the storage and disposal of high-level nuclear waste.

        The Uranium Mill Tailings Radiation Control Act ("UMTRCA") and the Uranium Mill Tailings Remedial Action Amendments Act are intended to protect public health and the environment from hazards associated with uranium ore milling wastes at active and inactive uranium mills. UMTRCA designates specific inactive mill sites for remedial action, and gives the DOE the responsibility for carrying out remedial actions at these sites.

        The Low-Level Radioactive Waste Policy Act of 1980 ("LLRWPA") and the Low-Level Radioactive Waste Policy Amendments Act of 1985 ("LLRWPA Amendments") address the siting of new low-level radioactive waste disposal facilities. Each state is responsible for providing capacity for commercial low-level radioactive waste generated within its borders. The LLRWPA also encourages groups of states to enter into compacts providing for the development and operation of low-level radioactive waste disposal facilities. At the present time, state compacts have opened no new radioactive waste disposal facilities.

        The Resource Conservation and Recovery Act of 1976 ("RCRA"), as amended by the Hazardous and Solid Waste Amendments of 1984 ("HSWA"), provides a comprehensive framework for the regulation of the generation, transportation, treatment, storage, and disposal of hazardous waste. The intent of RCRA is to control hazardous wastes from the time they are generated until they are properly recycled or treated and disposed. RCRA prohibits improper hazardous waste disposal and imposes criminal and civil liability for failure to comply with its requirements. RCRA requires that hazardous waste generators, transporters, and operators of hazardous waste treatment, storage, and disposal facilities meet strict standards set by government agencies. In certain circumstances, RCRA also requires operators of treatment, storage, and disposal facilities to obtain and comply with RCRA permits. The Land Disposal Restrictions developed under the HSWA prohibit land disposal of specified wastes unless these wastes meet or are treated to meet Best Demonstrated Available Technology ("BDAT") treatment standards, unless certain exemptions apply.

        The Toxic Substances Control Act ("TSCA") provides the EPA with the authority to regulate over 60,000 commercially produced chemical substances. The EPA may impose requirements involving manufacturing, record keeping, reporting, importing, and exporting. The TSCA also established a comprehensive regulatory program for PCBs, which is analogous to the RCRA program for hazardous waste.

        The Clean Water Act, as amended, establishes standards, permits, and procedures for controlling the discharge of pollutants from wastewater sources.

        The Clean Air Act of 1970, as amended (the "Clean Air Act"), empowers the EPA and the states to establish and enforce ambient air quality standards and limits of emissions of pollutants from facilities. This has resulted in tight control over emissions from technologies like incineration.

        The Comprehensive Environmental Response, Compensation and Liability Act of 1980 ("CERCLA" or "Superfund"), and subsequent amendments under the Superfund Amendments and

8

Reauthorization Act ("SARA"), as implemented by the National Contingency Plan, provide for the investigation and remediation of sites containing hazardous substances. The Superfund program's regulations require that any remediation of hazardous substances meet applicable and relevant and/or appropriate regulatory requirements. Superfund also establishes strict and retroactive liability for parties who generated or transported hazardous substances, or owned and/or operated the sites containing them. This creates a strong incentive for proper management and disposal of hazardous waste.

        The Emergency Planning and Community Right to Know Act of 1986 ("EPCRA") requires companies to submit emergency and hazardous inventory forms to state and local agencies for all materials requiring a material safety data sheet under OSHA. EPCRA requires full disclosure of environmental releases to the public and contributes to public awareness and activism regarding corporate environmental management issues. To the extent a generator's waste can be reported as being recycled, public pressure may be eliminated or significantly reduced.

        The Pollution Prevention Act of 1990 establishes pollution prevention as a national objective, naming it a primary goal wherever feasible. The act states that if pollution cannot be prevented, materials should be recycled in an environmentally safe manner.

        Under the mandate of the Federal Facility Compliance Act ("FFCA"), the DOE is currently engaged in a program to treat and dispose of the mixed waste currently stored at its facilities. The FFCA required DOE to develop and comply with treatment and disposal plans for each of its facilities and charges the DOE with developing treatment and disposal capacity for these wastes where it does not currently exist. The plans must also address the need to treat and dispose of mixed wastes generated from the remediation of contaminated DOE sites.

Environmental Laws and Regulations Affecting the Use of the Company's Waste Treatment Technologies

        To the extent that the Company is engaged in the storage, processing, or disposal of mixed waste, the radioactive components are subject to the NRC regulations promulgated under the AEA, while the EPA, under RCRA, regulates the hazardous components of the waste. To the extent that these regulations have been delegated to the states, the state may also regulate mixed waste.

        Pursuant to the mandate of the AEA, NRC regulations and guidance address the classification and management of low-level radioactive waste. The NRC regulations also govern the technical, monitoring, and safety-related aspects of developing and operating low-level radioactive waste disposal facilities. Pursuant to its authority under the AEA, the NRC also has established licensing requirements and operating procedures for such facilities. The NRC requirements address siting criteria, site stability, the development and implementation of institutional controls for the facility (e.g., access restrictions, environmental monitoring, and site maintenance), facility operation, financial assurance, closure, and site stabilization. The Company's facilities implement NRC requirements through Agreement States' regulations and facility radioactive material licenses. The NRC has delegated this licensing authority to numerous state agencies, including agencies in those states in which the Company's facilities and operations are located.

        Under RCRA, wastes are classified as hazardous either because they are specifically listed as such or because they display certain hazardous characteristics. Under current regulations, waste residues derived from listed hazardous wastes are considered hazardous wastes unless they are delisted through a formal rulemaking process that may last a few months to several years. For this reason, waste residue that is generated by the treatment of listed hazardous wastes, such as waste treated with the Company's vitrification technologies, may be considered a hazardous waste without regard to the fact that this waste residue may be environmentally benign. Subsequent management of such waste residue would be subject to full RCRA regulation, including the prohibition against land disposal without treatment in compliance with BDAT. In some cases, there is no current technology to treat mixed wastes, although

9

EPA policy places these wastes on a low enforcement priority. The Company's ownership and operation of treatment facilities also exposes the Company to potential liability for cleanup of releases of hazardous wastes under RCRA.

        Operators of hazardous waste treatment, storage, and disposal facilities are required to obtain RCRA Part-B permits from the EPA or from states authorized to implement the RCRA program. The Company has developed procedures to ensure compliance with RCRA permit provisions at the Bear Creek Operations Facility, including procedures for ensuring appropriate waste acceptance and scheduling, waste tracking, manifesting and reporting, and employee training.

        When the Company engages in the transportation of hazardous materials, such as radioactive materials, it is subject to the requirements of the Hazardous Materials Transportation Act, as amended by the Hazardous Materials Transportation Uniform Safety Act. Pursuant to these statutes, the United States Department of Transportation regulates the transportation of hazardous materials in commerce. Shippers and carriers of radioactive materials must comply with both the general requirements for hazardous materials transportation and with specific requirements for the transportation of radioactive materials.

        CERCLA effectively imposes strict, joint, and several retroactive liabilities upon owners or operators of facilities where a release of hazardous substances has occurred, on parties who generated hazardous substances that were released at such facilities, and on parties who arranged for the transportation of hazardous substances to such facilities. The Company's ownership and operation of vitrification, storage, and incineration facilities on-site expose the Company to potential liability under CERCLA for releases of hazardous substances into the environment at those sites. In the event that off-site storage or disposal facilities utilized by the Company for final disposition of the glass and other residues from the Company's vitrification, incineration, and other treatment processes are subject to cleanup under CERCLA, the Company could incur liability as a generator of such materials or by virtue of having arranged for their transportation and disposal. The Company designs its DuraMelter™ and other processes to minimize the potential for release of hazardous substances into the environment. In addition, the Company has developed plans to manage and minimize the risk of CERCLA or RCRA liability, including the training of operators, use of operational controls, and structuring of its relationships with the entities responsible for the handling of waste materials and by-products.

        The Company's facilities may have to obtain permits under the Clean Water Act, the Clean Air Act, and corresponding state statutes. The necessity to obtain such permits depends upon the facility's location and the expected emissions from the facility. Additional state licenses or approvals may also be required. Further, many of the federal regulatory authorities described in this section have been delegated to state agencies; accordingly, the Company holds the required licenses, permits and other approvals from numerous states.

        The Clean Air Act imposes stringent requirements upon owners and operators of facilities that emit pollutants into the air. The Company believes that its treatment systems effectively trap particulates and prevent hazardous emissions from being released into the air, the release of which would violate the Clean Air Act. The Clean Air Act may require permits prior to the construction and operation of the Company's facilities, and may require additional emission controls and restrictions on materials stored, used, and incinerated at existing or proposed facilities.

        The Clean Water Act establishes standards, permits, and procedures for controlling the discharge of pollutants from wastewater sources. The Company believes that DuraMelters™ generally will not be subject to the water pollution control requirements of the Clean Water Act because DuraMelters™ are designed to have no residual wastewater discharge. However, the Clean Water Act's standard permits and procedures are potentially applicable to all other water discharged from, or reused at, facilities owned or operated by the Company.

10

        OSHA provides for the establishment of standards governing workplace safety and health requirements, including setting permissible exposure levels for hazardous chemicals that may be present in mixed wastes. The Company is required to follow OSHA standards, including the preparation of material safety data sheets, hazardous response training, and process safety management. The NRC has set regulatory standards for worker protection and public exposure to radioactive materials or wastes.

Competition

        In its federal services and commercial services operations, the Company's competitors range from major national and regional environmental service and consulting firms that have large environmental remediation staffs to small local firms. Many of the major national and regional environmental service and consulting firms have greater financial, management, and marketing resources than the Company. The availability of skilled technical personnel, quality of performance, safety, diversity of services, and price are the key competitive factors in this market.

        The market for the Company's waste treatment services is characterized as the packaging, transportation, treatment, stabilization, and disposal of certain radioactive, hazardous, and mixed wastes. The Company is aware of competition from several large companies that have substantially greater financial and technical resources and numerous other smaller companies. Any of such companies may possess or develop alternate technologies superior to those of the Company. The predominant waste treatment and disposal methods include direct landfill disposal, on-site containment/processing, and incineration, or other thermal treatment methods. Competition is based primarily on cost, regulatory, and permit restrictions, technical performance, dependability, and environmental integrity. The Company believes that it will be able to compete favorably on the basis of these factors. The Company also believes that it has several competitive advantages over its competitors, including its proprietary waste treatment technologies, its comprehensive approach to waste treatment, demonstrated commercial success of its technologies, reputation for providing quality service to its customers, and its low-level radioactive waste disposal landfill site.

Research and Development Activities

        The Company does not conduct or fund its own research and development activities. In connection with various Company contracts or subcontracts, The Vitreous State Laboratory of The Catholic University of America in Washington, D.C. ("VSL") conducts research and development under fixed price and cost reimbursable contracts. Under these contracts, the research is supervised by Drs. Macedo and Litovitz and all inventions and discoveries are owned by them and licensed to the Company under an exclusive license agreement.

        For waste cleanup projects in which the VSL's technical services are utilized by the Company, the Company reimburses the VSL on a time and expense basis and includes the estimated cost for such services in its formal bid proposal. The VSL is a not-for-profit institution, therefore it does not include fees or percentage profits in its cost estimates.

Patents and Other Intellectual Property Rights

        The Company owns a number of patents and related trademarks pertaining to the detection, storage, decontamination, processing, and handling of radioactive and hazardous waste materials that are necessary for its business. Specifically, the issued and active patents owned by the Company relate to steam reforming, vitrification, grouting, waste water treatment, metal decontamination, nuclear waste packaging and storage modules, ion-exchange materials and processes, heat exchangers, decontamination of materials and equipment, and assaying of materials that are used in its commercial waste processing operations. As a result of various acquisitions and internal technology development, the Company owns rights in 56 U.S. patents, 70 foreign patents, and 11 pending foreign patent

11

applications. Pursuant to an agreement with Westinghouse Electric Corporation ("Westinghouse"), now Viacom, Inc., the Company has granted Westinghouse a non-exclusive royalty free license to practice the technologies covered by certain of the patents acquired by the Company. From time to time, the Company acquires or licenses technologies from third parties that complement its existing waste processing technologies. In February 2000, the Company entered into an exclusive license agreement in the radioactive field for the patents and intellectual property rights to the desorber technology from the inventor of this technology. The agreement provides for a royalty free right to the technology for a three-year period ending in February 2003, after which the Company could extend the right for an annual fee. In February 2003, the Company decided not to exercise the rights to the technology.

        The Company licenses the patents and intellectual property rights to its proprietary vitrification and ion-exchange technologies from the inventors of such technologies. Drs. Macedo and Litovitz, the inventors, license the patents and the proprietary rights to such technologies to the Company under an exclusive license agreement. The exclusive license agreement expires upon the expiration of the last patent covered by the license agreement, which is currently in the year 2019. The exclusive license agreement, which currently encompasses 13 U.S. patents, 15 foreign patents, and 1 pending foreign patent application, also includes any process patents or technology rights related to the licensed field which is subsequently developed by the VSL or Drs. Macedo and Litovitz. The Catholic University of America has agreed that all patents and technologies developed at the VSL belong to Drs. Macedo and Litovitz and not to the University. In turn, Drs. Macedo and Litovitz exclusively license the vitrification and ion exchange technology rights and patents developed at the VSL to the Company.

        The Company requires each of its employees to enter into standard agreements pursuant to which each employee agrees to keep confidential all proprietary information of the Company and to assign to the Company all rights in any proprietary information or technology developed by the employee during his or her employment or made thereafter as a result of any inventions conceived or work done during such employment. Despite these precautions, it may be possible for a third party to copy or otherwise obtain and use the Company's technology without authorization or to develop similar technology independently. In addition, effective patent and trade secret protection may be unavailable or limited in certain foreign countries.

        DURATEK®, ALPS®, CNSI®, and Chem-Nuclear® are some of the 18 registered trademarks held by the Company and DuraMelter™ is a common law trademark.

Employees

        As of December 31, 2002, the Company employed approximately 1,280 employees, of which approximately 84 are temporary field-assigned employees performing services for clients. The Company contracts with most of the field-assigned personnel on an as-needed basis and such personnel are not regular, full-time employees of the Company. The Company reduced its staff at its Bear Creek Operations facility by approximately 120 employees in 2002 in order to increase efficiency within its commercial processing group. To date, the Company has been successful in attracting and retaining qualified technical personnel and believes that its relations with its employees are good.

Financial Information About Geographic Areas

        The Company's revenues are substantially derived from domestic operations. Results of international operations are not significant.

Available Information

        The Company was incorporated in Delaware in 1982. The Company's principal executive offices are located at 10100 Old Columbia Road, Columbia, Maryland 21046. The Company's telephone number is (410) 312-5100 and its website address is www.Duratekinc.com. The Company makes its

12

annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and amendments to these reports available on its website free of charge as soon as practicable after they are filed with the Securities and Exchange Commission.

Item 2. Properties

        The Company leases approximately 35,000 square feet of office space in Columbia, Maryland, which it uses as its administration and general corporate offices. The initial lease term expires on December 31, 2006. In addition, the Company leases approximately 23,000 square feet of office space in Columbia, South Carolina and approximately 15,000 square feet of office space in Lakewood, Colorado. Both of these lease terms expire on December 31, 2005.

        The Company owns real property assets, including approximately 50 acres of land in Oak Ridge, Tennessee, upon which the primary waste processing operations are located, an additional 50 acre parcel in Oak Ridge, Tennessee, at which additional waste processing operations are conducted and a 13.5 acre site in Memphis, Tennessee where large component projects are conducted.

        The Company also maintains the operating rights to the Barnwell disposal operation in Barnwell, South Carolina. This facility operates a commercial low-level radioactive waste disposal landfill site that is owned by the State of South Carolina, and leased to the Company under a long-term lease. The lease term expires on April 5, 2075.

Item 3. Legal Proceedings

        In May 2000, Toxgon Corporation ("Toxgon") filed a complaint for patent infringement against BNFL, Inc. ("BNFL") and the Company in the U.S. District Court for the Eastern District of Washington. In the complaint, Toxgon alleged, among other things, that BNFL and the Company infringed the claims of one of its U.S. patents. In August 2000, BNFL and the Company, in lieu of filing an answer, filed a motion to dismiss Toxgon's complaint for lack of subject matter jurisdiction. In September 2002, the District Court granted BNFL's and the Company's motion to dismiss.

        Toxgon filed a Notice of Appeal in the Ninth Circuit in October 2000. The issue on appeal was whether the District Court erred in dismissing the case for lack of subject matter jurisdiction. The Ninth Circuit transferred the case to the United States Court of Appeals for the Federal Circuit ("CAFC") in March 2002. In December 2002, the CAFC vacated the District Court's dismissal for lack of subject matter jurisdiction and remanded the action to the District Court for further proceedings. Toxgon filed an amended complaint in the District Court in November 2002, prior to the decision from the CAFC. The Company's answer to the amended complaint was filed on January 30, 2003. The Company believes that Toxgon's claims are frivolous and without merit.

        On June 22, 2001, the Company and two of its executive officers were sued in Federal District Court in Baltimore, Maryland by an individual stockholder on behalf of himself and other similarly situated stockholders of the Company. The putative class action suit alleges that certain statements and information included in the Company's press releases and in the periodic reports filed by it with the Securities and Exchange Commission contained materially false and misleading information in violation of the federal securities laws. The Company filed a motion to dismiss the complaint. In response, the plaintiff filed an amended complaint which mooted the Company's motion to dismiss. The Company then filed a motion to dismiss the amended complaint, which the plaintiff opposed. In orders dated April 26, 2002, the District Court granted the motion to dismiss in its entirety and entered judgment in favor of the Company and the executive officers. On or about May 24, 2002, the plaintiff filed a notice of appeal. The appeal is currently pending in the United States Court of Appeals for the Fourth Circuit. The parties have completed their briefing and oral arguments are expected to be heard in May 2003.

        On December 2, 1999, the Company's wholly owned subsidiary, Scientific Ecology Group, Inc. ("SEG") (now named Duratek Services, Inc.), was named as a defendant in an adversary proceeding in the United States Bankruptcy Court for the District of Massachusetts. The Chapter 11 Trustee, on behalf of the debtor Molten Metal Technology, Inc. ("MMT") and its creditors, filed an adversary "Complaint to Avoid Fraudulent Transfer" naming as defendants Viacom Inc., the successor to CBS Corporation and Westinghouse Electric Corporation ("Westinghouse"), and SEG. The complaint alleges that the sale of Westinghouse's interest in a joint venture to MMT resulted in a fraudulent conveyance. The primary allegations against SEG are that MMT's release of SEG from obligations to pay $8 million to equalize capital expenditures and additional amounts for MMT's share of profits, and MMT's assumption of at least $1.5 million of SEG's liabilities, are avoidable because MMT did not receive reasonably equivalent value for the transfers. The complaint purports to state four bankruptcy and five common law counts. The Company intends to vigorously contest MMT's allegations on the basis that MMT did in fact receive reasonably equivalent value for its transfers. In addition, the Company may have a right of indemnification from Westinghouse pursuant to the relevant purchase agreement. It is too early in the litigation to provide an accurate assessment of the Company's liability, if any. Westinghouse has agreed to assume all litigation costs associated with the defense of the case, but has reserved the right to challenge the Company's claim for indemnification for any settlement or judgment that may arise from the case. Westinghouse has moved to dismiss the complaint filed by the Chapter 11 Trustee. While Westinghouse's motion to dismiss was pending, the Chapter 11 Trustee sought to amend its complaint and that motion was granted. After the amended complaint was filed, Westinghouse filed a motion to dismiss the common law counts and the Court granted that motion.

        In addition, from time to time, the Company is a party to litigation or administrative proceedings relating to claims arising from its operations in the normal course of business. Management of the Company, on the advice of counsel, believes that the ultimate resolution of such litigation or administrative proceedings currently pending against the Company is unlikely, either individually or in the aggregate, to have a material adverse effect on the Company's results of operations or financial condition.

Item 4. Submission of Matters to a Vote of Security Holders

        The Company did not submit any matters to a stockholder vote during the last quarter of the fiscal year ended December 31, 2002.

Part II

Item 5. Market for Registrant's Common Equity and Related Stockholder Matters

        The Company's Common Stock is quoted on the NASDAQ National Market under the symbol "DRTK". The following table sets forth, for the periods indicated, the high and low sale prices of the Common Stock. The last reported sale price of the Common Stock on the NASDAQ National Market on March 17, 2003 was $8.05.

		Price Range of Common Stock
		High		Low
Year ended December 31, 2002:
	4th quarter	$	9.71	$	5.90
	3rd quarter		7.50		5.31
	2nd quarter		7.15		4.80
	1st quarter		5.09		2.77
Year ended December 31, 2001:
	4th quarter	$	7.60	$	3.91
	3rd quarter		6.15		4.00
	2nd quarter		5.15		2.50
	1st quarter		8.00		2.63

        As of March 17, 2003, there were 1,562 holders of record of the Common Stock and the Company estimates that there were approximately 4,200 beneficial holders.

        The Company has never declared or paid a cash dividend on its Common Stock and was prohibited from paying dividends under its bank credit facility in 2001 and 2002. The Company may not pay dividends on any of the Common Stock unless the Company has paid all accumulated dividends on all of the outstanding shares of 8% Cumulative Convertible Redeemable Preferred Stock (the "Convertible Preferred Stock"). As of December 31, 2002, the Company had accrued dividends of approximately $2.5 million on the outstanding shares of the Convertible Preferred Stock. On February 28, 2003, the Company's Bank Credit Facility (the "Facility") was amended. The amended Facility permits the Company to restart the payment of preferred dividends on the Company's Convertible Preferred Stock in 2003 and pay accrued dividends in 2004, subject to the satisfaction of certain conditions set forth in the amended Facility. The Company will pay dividends on the Convertible Preferred Stock out of funds legally available in accordance with the terms of the Convertible Preferred Stock, which require the payment of quarterly dividends of approximately $315,000 or $2.00 per share. The Company currently intends to retain earnings primarily for working capital and development of waste treatment technologies and therefore does not anticipate paying any cash dividends on its Common Stock in the foreseeable future. See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources."

Effective January 1, 2002, the Company adopted the provisions of Statement of Financial Accounting Standards ("SFAS") No. 142, Goodwill and Other Intangible Assets. Under SFAS No. 142, the Company is no longer amortizing goodwill but rather testing such assets for impairment on annual basis. If the Company had been required to adopt the provisions of the pronouncement effective as of January 1, 1998, net income (loss) and diluted net income (loss) per share for the years ended December 31, 2001, 2000, 1999, and 1998 would have been $(2.9) million and $(0.21), $(9.3) million and $(0.69), $11.6 million and $0.57 and $(3.6) million and $(0.27), respectively.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

        The following discussion should be read in conjunction with the Company's consolidated financial statements and the notes thereto that follow in this Form 10-K. In the fourth quarter of 2002, the Company decided to reclassify costs associated with the support of direct operations, which were previously included as selling, general and administrative expenses, to cost of revenues. The corresponding amounts for all periods presented have been reclassified to conform to this presentation.

Overview

        Duratek, Inc., together with its wholly owned subsidiaries (the "Company" or "Duratek"), provides safe, secure radioactive materials disposition and nuclear facility operations for commercial and government customers. The Company's operations are organized into three primary segments: (i) Federal Services, (ii) Commercial Services, and (iii) Commercial Processing and Disposal.

        The Company's Federal Services operations primarily provide on-site waste processing and disposal services, off-site waste disposition, on-site management of nuclear facility operations, and on-site clean up (remedial action) services on large government projects for the United States Department of Energy ("DOE") and other governmental entities. The Company's services include program development, project management, nuclear facility operation, waste characterization, packaging and shipping of waste, selected technical services, and site cleanup. Revenues derived from the Company's Federal Services operations represented approximately 46.4%, 42.9%, and 32.5% of the Company's total revenues during 2002, 2001, and 2000, respectively.

        The Company's Commercial Services operations provide waste treatment and disposition services to a diverse group of commercial clients, including nuclear power utilities. These services include water processing, nuclear waste handling and treatment, transportation, licensing, packaging, heavy hauling, disposal, and nuclear facility decontamination and decommissioning ("D&D"). Revenues derived from Commercial Services operations represented approximately 22.3%, 25.7%, and 28.3% of the Company's total revenues during 2002, 2001, and 2000, respectively.

        The Company conducts its Commercial Processing and Disposal operations at its three Tennessee locations: the Bear Creek Operations Facility in Oak Ridge, the Company's facility in Memphis, and the Gallaher Road Operations Facility in Kingston. The Company also operates two facilities in Barnwell, South Carolina: the Duratek Consolidation & Services Facility ("DCSF") and the Barnwell Low-Level Radioactive Waste Management Disposal Facility. The technologies used at the Tennessee based processing operations include incineration, compaction, metal decontamination and recycling, and Green is Clean. Revenues derived from the Company's Commercial Processing and Disposal operations

17

represented approximately 31.3%, 31.4%, and 39.2% of the Company's total revenues in 2002, 2001, and 2000, respectively.

        The Company incurred a substantial operating loss in 2000 primarily as a result of operational problems experienced at the Company's Bear Creek Facility and the Company's Memphis facility during the fourth quarter of 2000. The operational problems at these facilities and related losses on two significant contracts also adversely affected the Company's results for 2001, particularly in the first and fourth quarters of the year. The 2001 results included a $1.0 million provision for loss on a large component project and a $3.6 million accrual for costs associated with various high radiation customer waste. The Company's management has aggressively addressed these operational issues. Among other things, the Company has strengthened management resources and reporting, implemented personnel changes, modified waste processing, storage, transportation and burial methods, and improved cost accounting systems utilized at its commercial waste processing facilities. While management believes that these efforts were effective in 2002 and will prevent reoccurrence of the events that led to losses in its commercial waste processing operations in 2000 and 2001, no assurance can be given that some or all of the factors that led to these losses might not have a material adverse effect on future results of operations.

        The Company's future operating results will be affected by, among other things, the duration of commercial waste processing contracts and amount of waste to be processed by the Company's commercial waste processing operations pursuant to these contracts and the timing and scope of DOE waste treatment projects.

        In June 2000, the Company acquired the nuclear services business of Waste Management, Inc. which business is referred to as WMNS. The acquisition was accounted for under the purchase method of accounting.

Critical Accounting Policies

        The Company's accounting policies are described in Note 2 of Notes to Consolidated Financial Statements in Item 8. Management's discussion and analysis of its financial condition and results of operations are based upon the Company's consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). The preparation of these financial statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, the Company evaluates its estimates, including those related to cost to complete long-term contracts, the cost to D&D facilities and equipment, the recoverability of long-lived assets including goodwill, and contingencies and litigation. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results may differ from those estimates.

        Critical accounting policies are those that are both important to the presentation of the Company's financial condition and results of operations and require management's most difficult, complex, or subjective judgments. The Company's most critical accounting policies, which relate to revenue recognition, D&D liabilities, and recoverability of long-lived assets including goodwill, are discussed below.

Revenue Recognition

Commercial Waste Processing

        The commercial waste processing operations have short-term and long-term contracts with commercial companies to provide waste processing services. The Company's services are primarily

18

provided under fixed-unit price contracts. Under the fixed-unit price contracts, revenue is recognized as waste is processed. The Company records the associated costs with out-bound transportation, burial, and secondary waste processing as the related waste is processed. The Company's fixed-unit price contracts provide for additional customer billings if the characterization of the waste received is different from contract specifications or for certain increases in burial costs, both of which are estimated at the time of waste processing.

Contract Revenue and Cost Recognition

        The Federal Services and Commercial Services operations have long-term contracts to provide engineering and technical support services to the Federal government and its agencies and to commercial companies. The Company's services are provided under time-and-materials, cost-plus-fixed-fee and fixed-price contracts. Under time-and-materials contracts the Company records revenues based on hours incurred at agreed upon contractual rates. For cost-plus-fixed-fee contracts the Company records revenue based upon costs incurred and a proportionate amount of the fixed-fee or percentage stipulated in the contract. For fixed-price contracts, the Company recognizes revenue based upon applying the ratio of current cumulative costs incurred to total estimated cost at completion. The Company considers the nature of the work involved in determining whether such measures are appropriate. Cumulative revenues recognized may be less or greater than cumulative costs and profits billed at any point in time during a contract's term. The resulting difference is recognized as costs and estimated earnings in excess of billings on uncompleted contracts, a current asset, or unearned revenues, a current liability. Contracts typically provide for billing of costs incurred and estimated earnings on a monthly or quarterly basis. The estimates of revenues and expenses on client contracts change periodically in the normal course of business and due to contract modifications. The Company receives award fees on certain Federal government contracts which are accrued when estimable and collection is reasonably assured. Provisions for estimated losses on individual contracts are made in the period in which the loss was identified. Contract acquisition costs are expensed as incurred.

        Any estimation process, including that used in preparing contract estimates, involves inherent risk. The Company reduces the inherent risk relating to revenue and cost estimates through corporate policy, approval and monitoring processes, which includes a detailed monthly review and status report to management of all significant contracts with such risk.

D&D Liabilities

        The Company has responsibility related to the cost to D&D the facilities and equipment in Tennessee and South Carolina and equipment used at customer sites in the Commercial Services operations. Such costs will generally be paid upon closure of such facilities or disposal of such equipment. (See Note 9 of Notes to Consolidated Financial Statements).

        Similarly, under its license granted by the State of South Carolina and the Atlantic Interstate Low-Level Radioactive Waste Compact Implementation Act, the Company will be obligated for costs associated with the ultimate closure of the Barnwell Low-Level Radioactive Waste Disposal Facility in South Carolina and its buildings and equipment located at the Barnwell site. The Company has recorded accruals related to these D&D liabilities.

        In June 2001, the FASB issued SFAS No. 143, Accounting for Asset Retirement Obligations. SFAS No. 143 requires the Company to record the fair value of an asset retirement obligation ("ARO") as a liability in the period in which it incurs a legal obligation associated with the retirement of tangible long-lived assets that result from the acquisition, construction, development and/or normal use of the assets. The Company is also required to record a corresponding asset that is depreciated over the life of the asset. Subsequent to the initial measurement of the ARO, the ARO will be adjusted at the end of each period to reflect the passage of time and changes in the estimated future cash flows underlying

19

the obligation. The Company adopted SFAS No. 143 on January 1, 2003, as required, and recognized the following changes to the Company's consolidated financial statements: increase property, plant and equipment by $5.6 million and increase facility and equipment D&D liabilities by $9.5 million. The pre-tax difference of $3.9 million ($2.4 million after tax) was recognized as a cumulative effect of a change in accounting principle in the Company's first quarter results.

        Management updates its closure and remediation cost estimates for D&D on an annual basis. These estimates are based on current technology, regulations, and burial rates. Management is unable to reasonably estimate the impact that changes in technology, regulations, and burial rates will have on the ultimate costs. Changes in these factors could have a material impact on these estimates.

Recoverability of Long-Lived Assets, Including Goodwill

        The Company has made significant business acquisitions for which it has recorded the fair value of long-lived assets acquired and related goodwill and other intangible assets. The Company reviews long-lived assets and certain identifiable intangibles for impairment whenever events or circumstances indicate the carrying value of such assets may not be recoverable.

        The Company adopted the provisions of SFAS No. 142, Goodwill and Other Intangible Assets, and SFAS No. 144, Accounting for Impairment or Disposal of Long-Lived Assets, on January 1, 2002. Under the provisions of SFAS No. 142, goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but rather tested for impairment at least annually. SFAS No. 142 also requires that intangible assets with estimable useful lives be amortized over their respective useful lives and reviewed for impairment in accordance with the SFAS No. 144. As of December 31, 2002, the Company had $70.8 million of goodwill and $5.7 million of intangible assets with estimable useful lives on its consolidated balance sheet. The Company does not have any other intangible assets with indefinite useful lives.

        In connection with SFAS No. 142's transitional goodwill impairment evaluation, the Statement required the Company to perform an assessment of whether there was an indication that goodwill was impaired on the date of adoption. The Company was required to identify its reporting units and determine the carrying value of each reporting unit by assigning the assets and liabilities, including existing goodwill and intangible assets, to those reporting units. The carrying amount of each reporting unit was then compared with the determined fair value of each reporting unit. For each reporting unit, the determined fair value exceeded the carrying value and the second step of the impairment test was not required. The Company will test its goodwill for impairment annually, or more frequently if events and circumstances indicate an impairment, under the provisions of SFAS No. 142.

        In accordance with SFAS No. 144, long-lived assets, such as property, plant and equipment and purchased intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount of excess carrying value over fair value.

Results of Operations

        The table below sets forth certain consolidated statement of operations information as a percentage of revenues for the years ended December 31, 2002, 2001, and 2000. Certain amounts for 2001 and 2000 have been reclassified to conform to the presentation for 2002. In the fourth quarter of 2002, the Company decided to reclassify costs associated with the support of direct operations, which

20

were previously included as selling, general and administrative expenses, to cost of revenues. The corresponding amounts for all periods presented have been reclassified to conform to this presentation.

(in thousands)		2002			2001			2000
Revenues		$	291,536		$	279,173		$	228,542

	Net income (loss) attributable to common stockholders	$	12,486		$	(4,601	)	$	(10,555	)

        As previously indicated, the Company adopted the provisions of SFAS No. 142, Goodwill and Other Intangible Assets. Under SFAS No. 142, the Company is no longer amortizing goodwill, rather goodwill is tested for impairment at least annually. During 2002, the Company tested its goodwill as required by SFAS No. 142 and concluded that no impairment charge was required. If the provisions of SFAS No. 142 were in effect in 2001 and 2000, the Company's net loss would have been $2.9 million and $9.3 million, respectively.

Year Ended December 31, 2002 Compared to Year Ended December 31, 2001.

        Revenues increased by $12.3 million, or 4.4%, from $279.2 million in 2001 to $291.5 million in 2002. The increase in revenues is comprised of revenue increases of $15.3 million in Federal Services and $3.5 million in Commercial Processing and Disposal, offset by a revenue decrease of $6.5 million in Commercial Services. The increase in Federal Services revenues is primarily due to $17.3 million relating to increased work scope and the award of new work primarily relating to the K25/K27 Gaseous Diffusion Plant in Oak Ridge, Tennessee, the waste removal operations at the Hanford 100 area, work performed on the Hanford River Protection Program ("RPP") Vitrification projects, operation of a waste disposal facility at Hanford, Washington, and increased waste shipments at the Los Alamos National Laboratories. In addition, incremental revenues of $2.1 million were recognized in 2002 from a consolidated joint venture related to work performed to clean up and close an environmental technology site in Colorado. Partially offsetting these increases was a decrease of $4.4 million relating to revenues recognized in 2001 from the sale of limited rights to the Company's vitrification technology.

        Commercial Services revenues decreased by $6.5 million in 2002 due to the sale in April 2001of the technical support services business and by $3.4 million in the radiological engineering services business due to the completion of a large contract in 2001 relating to non-utility clean up and emergency response. Partially offsetting these decreases was an increase in revenues of $3.3 million from the site D&D business due to an increase in the volume of work on an existing contract.

21

        The increase in Commercial Processing and Disposal revenues was primarily the result of a $7.1 million increase in revenues from a large component project in Memphis and $1.6 million in revenues recognized by the Barnwell low-level radioactive waste disposal facility relating to a decision by the South Carolina Public Service Commission to allow a portion of the amortization expense of the Barnwell operating rights as a reimbursable allowable cost. The incremental revenues recognized during 2002 include an adjustment to record revenue for the reimbursement of this amortization expense since July 1, 2000, the date that the decision by the South Carolina Public Service Commission went into effect. Partially offsetting these increases were a $3.8 million decrease in revenues from the commercial processing operations in Tennessee, primarily due to a change in the processed waste mix and lower processing volume, and a $1.4 million decrease in revenues from the Barnwell low-level radioactive waste disposal facility and the Duratek Consolidation & Services Facility due to lower volumes of waste received in 2002.

        Gross profit increased by $20.7 million, or 49.6%, from $41.7 million in 2001 to $62.4 million in 2002. As a percentage of revenues, gross profit increased from 14.9% in 2001 to 21.4% in 2002. Gross profit from Federal Services increased by $0.2 million, or 0.6%, from $25.6 million in 2001 to $25.8 million in 2002. This increase is primarily attributable to the increase in revenues, offset by the gain in 2001 of $4.2 million on the sale of limited rights to the Company's vitrification technology.

        Gross profit from Commercial Services decreased by $1.0 million, or 5.5%, from $18.3 million in 2001 to $17.3 million in 2002. This decrease in gross profit was primarily due to the decrease in revenues from the radiological engineering services business, from the technical support services business that was sold in April 2001, and the completion of a large contract in 2001 relating to non-utility clean up and emergency response, partially offset by an increase in gross profit from the site D&D business.

        Gross profit from Commercial Processing and Disposal increased by $21.5 million, from a negative gross profit of $2.1 million in 2001 to gross profit of $19.4 million in 2002. This increase was primarily due to a decrease in labor expense as a result of a reduction in the work force, losses recognized in 2001 on two significant contracts, a decrease in transportation expense due to the increased use of rail transportation, lower material expense, a more favorable mix of waste than previously estimated on a significant high radiation project completed in 2002, and lower burial expense relating to the commercial processing operations. In addition, the $1.6 million in revenues recognized by the Barnwell low-level radioactive waste disposal facility on the amortization of Barnwell operating rights also contributed to the increase.

        Selling, general and administrative expenses decreased by $1.4 million, or 4.0%, from $35.0 million in 2001 to $33.6 million in 2002. As a percentage of revenues, selling, general and administrative expenses decreased from 12.5% in 2001 to 11.5% in 2002. The decrease in selling, general and administrative expenses is primarily attributable to a reduction in marketing expense, partially offset by higher personnel related expenses.

        Interest expense, net of interest income, decreased by $5.0 million from $10.4 million in 2001 to $5.5 million in 2002. The decrease was the result of the lower average borrowings and lower interest rates.

        During 2002, the Company incurred income tax expense of $9.7 million, compared to an income tax benefit of $0.7 million in 2001 as a result of the Company's 2001 operating loss. The Company's effective tax rate for 2001 was a benefit of 19.8% compared with an expense of 41.0% in 2002.

Year Ended December 31, 2001 Compared to Year Ended December 31, 2000.

        Revenues increased by $50.6 million, or 22.2%, from $228.5 million in 2000 to $279.2 million in 2001. The increase in revenues is comprised of revenue increases of $45.3 million in Federal Services

22

and $6.8 million in Commercial Services, offset by a revenue decrease of $1.8 million in Commercial Processing and Disposal. The increase in revenues from Federal Services is primarily the result of an increase of $34.3 million in revenues from the federal services business of WMNS, which was acquired in June 2000, and an increase of $8.9 million from the Hanford River Protection Project.

        The increase in revenues from Commercial Services is primarily the result of an increase in revenues of $21.2 million from environmental consulting and D&D services, partially offset by a $11.8 million decrease in revenues from the sale of the staff augmentation business and a $3.4 million decrease in revenues from the sale of the computer consulting services business. The staff augmentation business, which had revenues of $6.4 million and $18.2 million in 2001 and 2000, respectively, was sold in June 2001 for an amount approximating book value. The computer consulting services business, which had revenues of $3.4 million in 2000, was sold in November 2000.

        The decrease in revenues from Commercial Processing and Disposal is the result of a $4.7 million decrease in revenues from commercial processing services at the Company's processing facilities located in Tennessee (which includes the Bear Creek and Memphis facilities) and a $1.9 million loss reserve recognized in 2001 on a significant contract, offset by a $4.4 million increase in revenues from the Barnwell low-level radioactive waste disposal facility, to which the Company acquired the operating rights as part of the WMNS acquisition.

        Gross profit increased by $16.6 million, or 66.4%, from $25.1 million in 2000 to $41.7 million in 2001. As a percentage of revenues, gross profit increased from 11.0% in 2000 to 14.9% in 2001. The increase in gross profit percentage was the result of operational problems at the Company's Bear Creek and Memphis facilities in 2000 that were not as significant in 2001, together with the positive effects of the sale of limited rights to the Company's vitrification technology. The increase in the amount of gross profit is comprised of an increase of $11.1 million in Federal Services and an increase of $10.2 million in Commercial Services, which was partially offset by a decrease of $4.7 million in Commercial Processing and Disposal.

        The $11.1 million increase in Federal Services gross profit is primarily the result of a $4.3 million increase from the federal services business acquired from WMNS and a $4.2 million increase from the sale of limited rights to the Company's vitrification technology.

        Commercial Services gross profit increased by $10.2 million in 2001 compared to 2000. The increase is related to an increase in environmental consulting, and D&D services.

        Commercial Processing and Disposal gross profit decreased by $4.7 million in 2001 compared to 2000. The decrease in gross profit is primarily related to a $4.8 million decrease in gross profit from the Memphis facility a $1.7 million decrease in gross profit from the recognition of a loss on a large component steam generator project, and a $0.9 million relating to the Barnwell low-level radioactive waste disposal facility and the Duratek Consolidation and Services Facility, partially offset by an increase in gross profit of $2.7 million from the Bear Creek Facility. In 2001, the Company's Management had begun to aggressively address the operational problem experiences at the Company's Tennessee processing facility in 2000. Despite these efforts, the gross profit at the Tennessee processing facilities was negatively affected in 2000 and 2001 due to a series of operational issues, including delays in implementing new waste processing strategies and increased labor, transportation and burial costs, and related losses recognized in 2001 on two significant contracts. Included in the 2001 results are accruals of $3.6 million for processing, transportation and disposal of various high radiation customer waste. These accruals are included in waste processing and disposal liabilities in the Company's consolidated balance sheets.

        Selling, general and administrative expenses increased by $5.0 million, or 16.8%, from $30.0 million in 2000 to $35.0 million in 2001. As a percentage of revenues, selling, general and administrative expenses decreased from 13.1% in 2000 to 12.5% in 2001. Selling, general and administrative expenses

23

incurred by WMNS in 2001 were approximately $11.2 million compared to $7.3 million in 2000. The remaining increase in selling, general and administrative expenses is primarily due to activities supporting higher revenues.

        Interest expense, net, increased by $1.6 million from 2000 to 2001. The increase was the result of increased borrowings to fund working capital needs and the acquisition of WMNS together with higher borrowing rates as a result of amendments to the Company's credit facility.

        During 2001, the Company recognized an income tax benefit of $0.7 million as a result of the Company's operating loss. As of December 31, 2001, the Company had a net operating loss carryforward of approximately $12.1 million for Federal tax purposes. The Company's effective tax rate for 2001 was a benefit of 19.8% compared with a benefit of 36.2% in 2000. The effective tax rate for 2001 was significantly less than 2000 due to the non-deductibility of goodwill, primarily associated with the 2000 WMNS acquisition.

Liquidity and Capital Resources

        During 2002, the Company's operating activities provided net cash of $37.1 million. The net cash provided by operating activities in 2002 was primarily generated by $25.6 million in income from operations before depreciation and amortization and the reduction in the investment in working capital of $11.5 million. During 2001 and 2000, the Company's operating activities provided net cash of $13.3 million and $8.0 million, respectively. The net cash provided by operating activities in 2001 was primarily generated by $11.3 million in income from operations before depreciation and amortization and the reduction in the investment in working capital of $4.5 million. The net cash provided by operating activities in 2000 was primarily generated from operations of the Barnwell low-level radioactive disposal facility in South Carolina. Under South Carolina law, the Company is required to bill customers based on the amounts agreed to with the State. On an annual basis, following the State's year-end of June 30, the Company remits amounts billed to customers and collected of the waste disposal site less the amount earned by the Company as revenue for operating the site during such fiscal year (see Note 2 of Notes to Consolidated Financial Statements).

        During 2002, the Company used $2.8 million in net cash for investing activities consisting primarily of $2.6 million for purchases of property and equipment. During 2001, the Company used $2.4 million in net cash for investing activities consisting primarily of purchases of property and equipment of $4.2 million. During 2000, the Company used net cash of $76.1 million for investing activities, including $68.7 million in the acquisition of WMNS and $14.9 million for purchases of property and equipment, which were partially offset by the net proceeds received by the Company from the sale of DuraTherm of $7.6 million in February 2000.

        Net cash provided by operating activities in 2002 were used principally to repay borrowings under the Company's revolving credit facility and to pay down long-term debt. Under the terms of the June 8, 2000 purchase agreement between the Company and WMI, WMI provided short-term project financing at a fixed rate of 9.0% to the Company for the design and construction phase of a project, which was completed in March 2002. In 2002, the Company repaid all of the borrowings, plus accrued interest, with cash generated from the project.

        Net cash provided by operating activities in 2001 were used principally to repay borrowings under the Company's revolving credit facility and pay down long-term debt. During 2000, net cash used in investing activities were funded with $8.0 million provided by operating activities and $68.5 million from financing activities, principally from borrowings under the Company's revolving credit facility and long-term debt.

        At December 31, 2002, the Company's amended credit facility consisted of a five year $40.0 million revolving line of credit (which included temporary limits from $15.0 million to $35.0 million to meet

24

certain working capital requirements of the Company), a five year $50.0 million term loan, and a six and one-half year $40.0 million term loan. The term loans must be repaid in an amount equal to 50% of excess cash flows, as defined in the credit agreement. Borrowings under the credit facility bear interest at LIBOR plus an applicable margin or, at the Company's option, the prime rate plus an applicable margin. The applicable margin is determined based on the Company's performance and can range from 2.75% to 5.0% for LIBOR based borrowings and 1.75% to 4.0% for prime based borrowings. The facility requires the Company to maintain certain financial ratios and restricted the payment of dividends on the Company's common stock and preferred stock and the Company's ability to make acquisitions. At December 31, 2002, the Company had accrued dividends of $2.5 million on its outstanding convertible redeemable preferred stock, which are included in other noncurrent liabilities on the consolidated balance sheets.

        As of December 31, 2002, the Company had no outstanding borrowings under its revolving line of credit facility, $22.4 million of five year term loans bearing interest at LIBOR plus 3.25% (4.65%) and $38.8 million of six and one-half year term loans bearing interest at LIBOR plus 3.75% (5.15%).

        In accordance with the terms of the March 2002 amendment to the Company's bank credit agreement, the amount of available borrowings under the revolving line of credit after February 28, 2003 would be determined by the Company's lenders. On February 28, 2003, the bank credit agreement was amended to reset the amount of available borrowings under the revolving line of credit as well as to adjust certain covenants. Such covenants included several financial ratios and financial and operational requirements, which are measured on a monthly, quarterly, or annual basis. The amendment required a fee of approximately $115,000 and the payment of certain other fees and expenses. Under the amendment, the Company has no temporary limits under the $40.0 million revolving line of credit. In addition, the amended facility permits the Company to restart the payment of dividends on the Company's 8% Cumulative Convertible Redeemable Preferred Stock (the "Convertible Preferred Stock") in 2003, pay accrued dividends on the convertible redeemable preferred stock in 2004, and make permitted acquisitions, subject to the satisfaction of certain conditions set forth in the amended credit agreement. At March 1, 2003, after giving effect to this amendment, $34.4 million of additional borrowings were available under the revolving credit portion of the credit facility.

        The following table summarizes the Company's contractual cash obligations as of December 31, 2002 (in 000's):

	Less than 1 Year		1-3 Years		4-5 Years		After 5 Years		Total
Long-term debt	$	10,400	$	36,566	$	14,183	$	—	$	61,149
Capital leases		349		286		59		—		694
Operating leases		3,348		4,600		920		1		8,869
Convertible preferred stock dividends		1,260		2,520		—		—		3,780

        The Company has issued and outstanding 157,525 shares of Convertible Preferred Stock that is initially convertible into the Company's common stock at a conversion price of $3.00 per share and, if not previously converted, the Company is required to redeem the outstanding Convertible Preferred Stock on February 5, 2004 for $100 per share plus accrued and unpaid dividends, unless such date is extended with the approval of the holders of the Convertible Preferred Stock.

        The Company believes that cash flows from operations, cash resources at December 31, 2002 and, if necessary, borrowings available under its credit facility will be sufficient to meet its operating needs, including the quarterly preferred dividend payments of approximately $315,000 for at least the next twelve months.

New Accounting Pronouncements

        In November 2002, the Emerging Issues Task Force reached a consensus on Issue No. 00-21 Revenue Arrangements with Multiple Deliverables ("EITF 00-21"). EITF 00-21 addresses the accounting, for contractual arrangements in which multiple revenue-generating activities are performed. In some situations, the different revenue-generating activities (deliverables) are sufficiently separable and there exists sufficient evidence of fair values to account separately for the different deliverables (that is, there are separate units of accounting). In other situations, some or all of the different deliverables are interrelated closely or there is not sufficient evidence of fair value to account separately for the different deliverables. EITF 00-21 addresses when and, if so, how an arrangement involving multiple deliverables should be divided into separate units of accounting. EITF 00-21 is effective for the Company for contracts executed after June 30, 2003. The Company is in the process of determining the impact that EITF 00-21 will have on its consolidated financial statements.

        In November 2002, the FASB issued Interpretation No. 45, Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness to Others. This Interpretation elaborates on the disclosures to be made by a guarantor in its interim and annual financial statements about its obligations under guarantees issued. The Interpretation also clarifies that a guarantor is required to recognize, at inception of a guarantee, a liability for the fair value of the obligation undertaken. The initial recognition and measurement provisions of the Interpretation are applicable to guarantees issued or modified after December 15, 2002 and are not expected to have a material effect on the Company's consolidated financial statements. The disclosure requirements were effective for 2002 and are included in the notes to the consolidated financial statements that follow this Form 10-K.

        In December 2002, the FASB issued SFAS No. 148, Accounting for Stock-Based Compensation—Transition and Disclosure. This Statement amends SFAS No. 123, Accounting for Stock-Based Compensation, to provide alternative methods of transition for a voluntary change to the fair value method of accounting for stock-based employee compensation. In addition, this Statement amends the disclosure requirements of SFAS No. 123 to require prominent disclosures in both annual and interim financial statements. Certain of the disclosure modifications are required for fiscal years ending after December 15, 2002 and are included in the notes to the consolidated financial statements that follow in this Form 10-K.

        In January 2003, the FASB issued Interpretation No. 46, Consolidation of Variable Interest Entities, an interpretation of Accounting Research Bulletin No. 51. This Interpretation addresses the consolidation by enterprises of variable interest entities as defined in the Interpretation. The application of this Interpretation is not expected to have a material effect on the Company's consolidated financial statements.

Item 7A. Quantitative and Qualitative Disclosure about Market Risk

        The Company's major market risk relates to changing interest rates. At December 31, 2002, the Company had floating rate debt outstanding under its bank credit facility of $22.4 million bearing interest at LIBOR plus 3.25% (4.65%), and $38.8 million bearing interest at LIBOR plus 3.75% (5.15%). Average outstanding borrowings under the bank credit facility were $71.6 million during 2002. The Company currently has not entered into any derivative instruments to hedge its exposure to changing interest rates but may do so in the future. In addition, the Company does not have any foreign currency or commodity risk.

DURATEK, INC. AND SUBSIDIARIES

Notes to Consolidated Financial Statements

December 31, 2002, 2001, and 2000
(in thousands of dollars, except per share amounts)

(1)  Description of Business

        Duratek, Inc., together with its wholly owned subsidiaries (the "Company" or "Duratek"), provides safe, secure radioactive materials disposition and nuclear facility operations for commercial customers and government contractors. The Company possesses the capabilities, technologies, assets, facilities, and qualified personnel necessary to provide a full array of radioactive material characterization, processing, transportation, accident containment and restoration services, and final disposition. The Company operates through its five licensed commercial facilities and on-site at customer premises. The Company's 1,000-plus project managers and technical personnel strive to implement the optimal technology to meet each customer's needs. The Company's capabilities include both proprietary and other proven technologies, including over 120 Company owned patents, that can be used independently or in tandem to safely manage and process customers' radioactive material for long-term disposition.

(2)  Summary of Significant Accounting Policies

(a) Principles of Consolidation

        The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. Investments in joint ventures in which the Company does not have control or majority ownership are accounted for under the equity method. All significant intercompany balances and transactions have been eliminated in consolidation.

(b) Accounts Receivable

        Accounts receivable are recorded at the invoiced amount and generally do not bear interest. The allowance for doubtful accounts is the Company's best estimate of the amount of probable credit losses in the Company's existing accounts receivable. The Company determines the allowance based on historical experience and review of specific accounts. Account balances are written off against the allowance after all means of collection have been exhausted and recovery is considered remote.

(c) Cost and Estimated Earnings in Excess of Billings on Uncompleted Contracts, Unearned Revenue and Retainage

        Cost and estimated earnings in excess of billings on uncompleted contracts represent amounts recognized as revenue that have not been billed. Unearned revenue represents amounts billed and collected for which revenue has not been recognized. Contracts typically provide for the billing of costs incurred and estimated earnings on a monthly or quarterly basis. Retainage represents contractual amounts held in lieu of posting performance bonds and will be collected either upon meeting a predetermined milestone or upon completion of the contract. As of December 31, 2002 and 2001, retainage was $7,168 and $4,236, respectively, of which $2,199 as of the December 31, 2002 will be collected within the next 12 months and is included in prepaid expense and other current assets in the consolidated balance sheets.

33

(d) Property, Plant and Equipment

        Property, plant, and equipment are stated at cost. Equipment under capital leases are stated at the present value of minimum lease payments.

        Depreciation on plant and equipment is calculated on the straight-line method over the estimated useful lives of the assets. The estimated useful lives are: buildings 30 to 45 years, machinery and equipment 5 to 12 years, and furniture and fixtures 7 years. Equipment held under capital leases and leasehold improvements are amortized under the straight-line method over the shorter of the lease term or estimated useful life of the asset. Total depreciation and amortization of property, plant, and equipment for the years ended December 31, 2002, 2001 and 2000 was $8,929, $9,235 and $6,436, respectively. Maintenance and repairs that do not extend the lives of the assets are expensed as incurred.

(e) Impairment of Property and Purchased Intangibles

        In accordance with Statement of Financial Accounting Standards ("SFAS") No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, long-lived assets such as property, plant, and equipment and purchased intangibles subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized for the excess of carrying amount over the fair value of the asset.

(f) Goodwill and Other Intangible Assets

        Goodwill represents the excess of costs over fair value of assets of businesses acquired. The Company adopted the provisions of SFAS No. 142, Goodwill and Other Intangible Assets, as of January 1, 2002. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but instead tested for impairment at least annually in accordance with the provisions of SFAS No. 142. SFAS No. 142 also requires that intangible assets with estimable useful lives be amortized over their respective estimated useful lives, and reviewed for impairment in accordance with SFAS No. 144.

        Goodwill is tested annually for impairment, or more frequently if events and circumstances indicate that the asset might be impaired. An impairment loss is recognized to the extent that the carrying amount exceeds the asset's fair value.

        Prior to the adoption of SFAS No. 142, goodwill was amortized on a straight-line basis over the expected periods to be benefited, generally 30 years, and assessed for recoverability by determining whether the amortization of the goodwill balance over its remaining life could be recovered through undiscounted future operating cash flows of the acquired operation (see note 5).

34

(g) Revenue Recognition

Commercial Waste Processing

        The commercial waste processing operations have short-term and long-term contracts with commercial companies to provide waste processing services. The Company's services are primarily provided under fixed-unit price contracts. Under the fixed-unit price contracts, revenue is recognized as waste is processed. The Company records the associated costs with out-bound transportation, burial, and secondary waste processing as the related waste is processed. The Company's fixed-unit price contracts provide for additional customer billings if the characterization of the waste received is different from contract specifications or for certain increases in burial costs, both of which are estimated at the time of waste processing.

Contract Revenue and Cost Recognition

        The Federal Services and Commercial Services operations have long-term contracts to provide engineering and technical support services to the Federal government and its agencies and to commercial companies. The Company's services are provided under time-and-materials, cost-plus-fixed-fee and fixed-price contracts. Under time-and-materials contracts the Company records revenues based on hours incurred at agreed upon contractual rates. For cost-plus-fixed-fee contracts the Company records revenue based upon costs incurred and a proportionate amount of the fixed-fee or percentage stipulated in the contract. For fixed-price contracts, the Company recognizes revenue based upon applying the ratio of current cumulative costs incurred to total estimated cost at completion. The Company considers the nature of the work involved in determining whether such measures are appropriate. Cumulative revenues recognized may be less or greater than cumulative costs and profits billed at any point in time during a contract's term. The resulting difference is recognized as costs and estimated earnings in excess of billings on uncompleted contracts, a current asset, or unearned revenues, a current liability. Contracts typically provide for billing of costs incurred and estimated earnings on a monthly or quarterly basis. The estimates of revenues and expenses on client contracts change periodically in the normal course of business and due to contract modifications. The Company receives award fees on certain Federal government contracts which are accrued when estimable and collection is reasonably assured. Provisions for estimated losses on individual contracts are made in the period in which the loss was identified. Contract acquisition costs are expensed as incurred.

        Any estimation process, including that used in preparing contract estimates involves inherent risk. The Company reduces the inherent risk relating to revenue and cost estimates through corporate policy, approval and monitoring processes.

Disposal

        Revenues from the disposal operation, related to the Company's operating rights agreement with the State of South Carolina, are recognized as allowable costs are incurred plus 29% on certain of those allowable costs. Under the Atlantic Interstate Low-Level Radioactive Waste Compact Implementation Act (the "Act"), the Company is reimbursed for allowable costs identified by the South Carolina Public Service Commission. The Act requires that the Company bill customers based on amounts agreed upon with the State. The difference between the amounts

35

billed to its customers and collected and the amount earned by the Company as revenue under the Act is remitted to the State.

(h) Income Taxes

        Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

(i) Stock Option Plan

        The Company applies the intrinsic-value-based method of accounting prescribed by Accounting Principles Board ("APB") Opinion No. 25, Accounting for Stock Issued to Employees, and related interpretations including Financial Accounting Standards Board ("FASB") Interpretation No. 44, Accounting for Certain Transactions involving Stock Compensation, issued in March 2000, to account for its fixed-plan stock options. Under this method, compensation expense is recorded on the date of grant only if the current market price of the underlying stock exceeds the exercise price. SFAS No. 123, Accounting for Stock-Based Compensation and SFAS No. 148, Accounting for Stock Based Compensation-Transition and Disclosure, established accounting and disclosure requirements using a fair-value-based method of accounting for stock-based employee compensation plans. As allowed by SFAS No. 123, the Company has elected to continue to apply the intrinsic-value-based method of accounting described above, and has adopted only the disclosure requirements of SFAS Nos. 123 and 148. The following table illustrates the effect on net income (loss) if the fair-value-based method had been applied to all outstanding and unvested awards in each year:

	2002		2001			2000
Net income (loss) attributable to common stockholders	$	12,486	$	(4,601	)	$	(10,555	)
Income impact of assumed conversions — preferred stock dividends and charges for accretion		1,279		—			—
Net income attributable to common stockholders assuming conversion		13,765		(4,601	)		(10,555	)
Add stock-based employee compensation expense included in reported net income, net of tax		31		31			64
Deduct total stock-based employee compensation expense determined under fair-value-based method for all awards, net of tax		1,048		984			905
Pro forma net income (loss)	$	12,748	$	(5,554	)	$	(11,396	)
Pro forma net income (loss) per diluted common share	$	0.67	$	(0.41	)	$	(0.85	)

36

        The fair value of each stock option granted is estimated on the date of grant using the Black-Scholes option pricing model with the following weighted average assumption used for grants in 2002, 2001 and 2000:

	2002	2001	2000
Risk free interest rate	2.78-3.83%	5.5%	6.6%
Expected volatility	64%	64%	63%
Expected life	4 years	4 years	4 years
Contractual life	5 to 10 years	5 to 10 years	5 to 10 years
Expected dividend yield	0%	0%	0%
Fair value of options granted	$3.25	$3.06	$6.57

(j) Fair Value of Financial Instruments

        The estimated fair value of financial instruments, including accounts receivable, accounts payable, and long-term debt, approximate carrying values.

(k) New Accounting Pronouncements

        In November 2002, the Emerging Issues Task Force reached a consensus on Issue No. 00-21 Revenue Arrangements with Multiple Deliverables("EITF 00-21"). EITF 00-21 addresses the accounting, for contractual arrangements in which multiple revenue-generating activities are performed. In some situations, the different revenue-generating activities (deliverables) are sufficiently separable and there exists sufficient evidence of fair values to account separately for the different deliverables (that is, there are separate units of accounting). In other situations, some or all of the different deliverables are interrelated closely or there is not sufficient evidence of fair value to account separately for the different deliverables. EITF 00-21 addresses when and, if so, how an arrangement involving multiple deliverables should be divided into separate units of accounting. EITF 00-21 is effective for the Company for contracts executed after June 30, 2003. The Company is in the process of determining the impact that EITF 00-21 will have on its consolidated financial statements.

        In November 2002, the FASB issued Interpretation No. 45, Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness to Others. This Interpretation elaborates on the disclosures to be made by a guarantor in its interim and annual financial statements about its obligations under guarantees issued. The Interpretation also clarifies that a guarantor is required to recognize, at inception of a guarantee, a liability for the fair value of the obligation undertaken. The initial recognition and measurement provisions of the Interpretation are applicable to guarantees issued or modified after December 15, 2002 and are not expected to have a material effect on the Company's consolidated financial statements. The disclosure requirements are effective for 2002.

        In December 2002, the FASB issued SFAS No. 148, Accounting for Stock-Based Compensation—Transition and Disclosure, an amendment of FASB No. 123. This Statement amends SFAS No. 123 to provide alternative methods of transition for a voluntary change to the fair value method of accounting for stock-based employee compensation. In addition, this Statement amends the disclosure requirements of SFAS No. 123 to require prominent disclosures in both annual and

37

interim financial statements. Certain of the disclosure modifications are required for 2002 and are included in note 2(i).

        In January 2003, the FASB issued Interpretation No. 46, Consolidation of Variable Interest Entities. This Interpretation addresses the consolidation by enterprises of variable interest entities as defined in the Interpretation. The application of this Interpretation is not expected to have a material effect on the Company's consolidated financial statements.

(l) Research and Development

        The Company does not conduct or fund its own research and development activities. In connection with various Company contracts or subcontracts, The Vitreous State Laboratory of The Catholic University of America in Washington, D.C. ("VSL") conducts research and development under fixed price and cost reimbursable contracts. Under these contracts all inventions and discoveries are owned by the research scientists of the VSL and licensed to the Company under an exclusive license agreement.

        For waste cleanup projects in which the VSL's technical services are utilized by the Company, the Company reimburses the VSL on a time and expense basis and includes the estimated cost for such services in its formal bid proposal. The VSL is a not-for-profit institution, therefore it does not include fees or percentage profits in its cost estimates.

(m) Interest Expense, Net

        Interest expense presented in the Company's consolidated statement of operations is net of interest income. Interest income is not material to the results of the Company and therefore are not separately presented.

(n) Use of Estimates

        The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management of the Company to make estimates and judgments that affect the reported amounts of assets and liabilities and disclosures of contingencies at the date of the financial statements and revenues and expenses recognized during the reporting period. Significant estimates and judgments made by management include: (i) the amount of waste processing and disposal liabilities, (ii) the cost to decontaminate and decommission ("D&D") facilities and equipment, (iii) the cost to complete long-term contracts, (iv) recovery of long-lived assets, including goodwill, and (v) contingencies and litigation. Actual results could differ significantly from those estimates.

(o) Reclassifications

        Certain amounts for 2001 and 2000 have been reclassified to conform to the presentation for 2002. In the fourth quarter of 2002, the Company decided to reclassify costs associated with the support of direct operations, which were previously included as selling, general and administrative expenses, to cost of revenues. The corresponding amounts for all periods presented have been reclassified to conform to this presentation

38

(3)  Net Income (Loss) Per Share

        Basic net income (loss) per share is calculated by dividing net income (loss) attributed to common stockholders by the weighted average number of common shares outstanding for the period. Diluted net income (loss) per share is calculated by dividing net income (loss) by the diluted weighted average common shares, which reflect the potential dilution of stock options, convertible redeemable preferred stock, and restricted stock units that could share in the earnings of the Company. The reconciliation of amounts used in the computation of basic and diluted net income (loss) per share for the years ended December 31, 2002, 2001, and 2000 consist of the following:

			2002		2001			2000
Numerator:
	Net income (loss) attributable to common stockholders		$	12,486	$	(4,601	)	$	(10,555	)
	Plus: Income impact of assumed conversions—preferred stock dividends and charges for accretion			1,279		—			—
	Net income (loss) attributable to common stockholders assuming conversion		$	13,765	$	(4,601	)	$	(10,555	)
Denominator:
	Weighted-average shares outstanding			13,504		13,449			13,432
Effect of dilutive securities:
	Incremental shares from assumed conversion of:
		Employee stock options		260		—			—
		Restricted stock		95		—			—
		Convertible redeemable preferred stock		5,251		—			—
				5,606		—			—
	Diluted weighted average common shares outstanding			19,110		13,449			13,432
Basic net income (loss) per share			$	0.92	$	(0.34	)	$	(0.79	)
Diluted net income (loss) per share			$	0.72	$	(0.34	)	$	(0.79	)

        The effects on weighted average shares outstanding of options to purchase common stock and other potentially dilutive securities of the Company that were not included in the computation of diluted net income (loss) per share at December 31, 2002, 2001 and 2000 because the effect would have been anti-dilutive were, in thousands, 709, 6,483, and 6,812 shares, respectively.

39

(4)  Property, Plant and Equipment

        Property, plant and equipment at December 31, 2002 and 2001 consisted of the following:

	2002		2001
Land and land improvements	$	2,867	$	2,816
Buildings		40,827		40,776
Machinery and equipment		54,689		54,793
Leasehold improvements, furniture and fixtures		4,987		5,885
Construction in progress		493		397
		103,863		104,667
Less accumulated depreciation and amortization		34,576		28,784
	$	69,287	$	75,883

        Machinery and equipment under capital leases was $1,899, with accumulated depreciation of $1,174, and $1,899, with accumulated depreciation of $895, as of December 31, 2002 and 2001, respectively.

(5)  Goodwill and Other Intangible Assets

        Under SFAS No. 142, the Company is no longer amortizing goodwill, rather goodwill is tested for impairment at least annually. During 2002, the Company tested its goodwill in accordance with the standard and concluded that no impairment charge was required.

        The following table reconciles previously reported net income (loss) as if the provisions of SFAS No. 142 were in effect in 2001 and 2000.

	2002		2001			2000
Net income (loss) attributable to common stockholders	$	12,486	$	(4,601	)	$	(10,555	)
Add back goodwill amortization, net of tax		—		1,722			1,305
Adjusted net income (loss) attributable to common stockholders	$	12,486	$	(2,879	)	$	(9,250	)
Reported diluted net income (loss) per common share	$	0.72	$	(0.34	)	$	(0.79	)
Adjusted diluted net income (loss) per common share	$	0.72	$	(0.21	)	$	(0.69	)

        Other intangibles subject to amortization consist principally of amounts assigned to operating rights related to the Barnwell, South Carolina low-level radioactive waste disposal facility, covenants not-to-compete, and costs incurred to obtain patents. The Barnwell operating rights are being amortized on a straight-line basis over the remainder of the eight-year life of the facility. Covenants not to compete and patent amounts are being amortized over 10 and 17 years, respectively, on a straight-line basis. Other intangible assets, net of accumulated amortization as of December 31, 2002 and 2001 were $5,675 and $7,936, respectively. Aggregate amortization expense for 2002, 2001, and 2000 was $1,654, $3,593, and $2,473, respectively. Anticipated amortization expense for the next five years is $984 per year.

40

(6)  Long-Term Debt

        Long-term debt at December 31, 2002 and 2001 consisted of the following:

		2002		2001
Bank Credit Facility:
	Borrowings under revolving line of credit	$	—	$	12,500
	Term loans		61,149		71,800
			61,149		84,300
	Less: current portion of long-term debt		10,400		10,400
		$	50,749	$	73,900

        At December 31, 2002, the Company's Bank Credit Facility (the "facility") consisted of a five year $40,000 revolving line of credit (which included temporary limits from $15,000 to $35,000 to meet certain working capital requirements), a five year $50,000 term loan, and a six and one-half year $40,000 term loan. The term loans must be repaid in an amount equal to 50% of excess cash flows, as defined in the credit agreement. Borrowings under the facility bear interest at LIBOR plus an applicable margin or, at the Company's option, the prime rate plus an applicable margin. The applicable margin is determined based on the Company's performance and can range from 2.75% to 5.0% for LIBOR based borrowings and 1.75% to 4.0% for prime based borrowings. The facility requires the Company to maintain certain financial ratios and restricted the payment of dividends on the Company's common and preferred stock and the Company's ability to make acquisitions. At December 31, 2002, the Company had accrued dividends of $2,520 on its outstanding convertible redeemable preferred stock. The $40,000 revolving line of credit and the $50,000 term loan expires on June 8, 2005. The $40,000 term facility expires on December 8, 2006. The maturity dates may be accelerated based on certain conditions, as defined in the agreement.

        As of December 31, 2002, the Company had no outstanding borrowings under its revolving line of credit, $22,400 of five year term loans bearing interest at LIBOR plus 3.25% (4.65%) and $38,749 of six and one-half year term loans bearing interest at LIBOR plus 3.75% (5.15%). As of December 31, 2001, the Company had outstanding borrowings under its credit facility of $12,500 bearing interest at prime plus 3.0% (7.75%), $32,500 bearing interest at LIBOR plus 4.0% (5.91%) and $39,300 bearing interest at LIBOR plus 4.5% (6.41%).

        On February 28, 2003, the facility was amended to reset the amount of available borrowings under the revolving line of credit as well as to adjust certain covenants. Such covenants included several financial ratios and financial and operational requirements, which are measured on a monthly, quarterly, or annual basis. Under the amendment, the Company has no temporary limits under the $40,000 revolving line of credit and allows the Company to restart the payment of dividends on the Company's convertible redeemable preferred stock in 2003, pay accrued dividends on the convertible redeemable preferred stock in 2004, and make permitted acquisitions, subject to the satisfaction of certain conditions set forth in the amendment. As of March 1, 2003, after giving effect to this amendment, $34,400 of additional borrowings were available under the revolving line of credit.

        Aggregate maturities of long-term debt as of December 31, 2002 are as follows:

2003	$	10,400
2004		15,075
2005		21,491
2006		14,183
	$	61,149

41

        The Company paid interest of $4,230, $8,139, and $6,945 during the years ended December 31, 2002, 2001 and 2000, respectively.

(7)  Accrued Expenses and Other Current Liabilities

        Accrued expenses and other current liabilities at December 31, 2002 and 2001 consisted of the following:

	2002		2001
Salaries and related expenses	$	10,501	$	5,272
Amount due to the State of South Carolina		13,175		18,093
Contract costs—subcontractors		12,089		12,373
Other accrued expenses		7,850		3,739
	$	43,615	$	39,477

        The amount due to the State of South Carolina is payable by July 30 of the following year, pursuant to the provisions of the Act (see note 2(g)).

(8)  Waste Processing and Disposal Liabilities

        The Company's waste processing technologies create waste by products ("secondary waste"), which generally require further processing and disposal. The Company accrues the estimated costs of burial and transportation based on anticipated processing methods, characterization of the waste, and current disposal sites and rates. The ultimate cost of disposal will depend on the actual contamination of the waste, volume reduction, activity, and disposal density. At December 31, 2002 and 2001, the Company had accrued $4,491 and $5,262, respectively, related to secondary waste.

        In addition, the Company had accrued $5,445 and $8,899 for processed customer waste awaiting burial at December 31, 2002 and 2001, respectively, based on contractual rates, which are negotiated annually. The Company's accrual at December 31, 2001 included $3,652 for estimated costs to process and dispose of certain high radiation customer waste in excess of related contract revenue.

(9)  Facility and Equipment D&D

        The Company has responsibility related to the cost to D&D the facilities and equipment in Tennessee and South Carolina and equipment used at customer sites in the Commercial Services operations. Such costs will generally be paid upon closure of such facilities or disposal of such equipment.

        Similarly, the Company will be obligated for costs associated with the ultimate closure of the Barnwell Low-Level Radioactive Waste Disposal Facility in South Carolina and its buildings and equipment located at the Barnwell site. The Company has recorded accruals related to these D&D liabilities as follows:

(a) Tennessee Facilities

        Prior to the adoption of SFAS No. 143 on January 1, 2003, the Company had estimated the cost to D&D its commercial waste processing facilities and equipment in Tennessee to be approximately $21,177 and had been accruing such costs over 25 years, which is the facilities' estimated useful life.

        During the years ended December 31, 2002, 2001 and 2000, the Company recognized D&D expense of $553, $544, and $826, respectively. As of December 31, 2002 and 2001, the Company's liabilities for D&D were $7,613 and $7,263, respectively.

42

        The Company has purchased insurance to fund the Company's obligation to clean and remediate its Tennessee facilities upon closure. The Company is accounting for these insurance policies using deposit accounting, whereby a portion of the premiums paid are viewed as funding to cover the Company's obligation and is capitalized as a deposit asset. The remainder of the premium is being charged to earnings in the period in which the premiums are paid. As of December 31, 2002 and 2001, the deposit asset was $1,209 and $932, respectively, and is included in other assets in the consolidated balance sheets. Related insurance expense for the years ended December 31, 2002, 2001 and 2000 was $627, $439, and $386, respectively. In addition, in 2002, the Company was required to place $1,000 in escrow relating to the insurance policy for the Bear Creek Operations Facility.

(b) Barnwell Low-Level Radioactive Waste Disposal Facility

        Effective July 6, 2000, the State of South Carolina passed into law the Act (see note 2(g)) that, in addition to the new rate-controlled structure, also establishes annual volume limits on waste that can be accepted at the site for disposal. The maximum annual volume declines from 160,000 cubic feet to 35,000 cubic feet over an eight-year period. At the end of the eight-year period, the site will remain open for receipt of waste from only the three Atlantic Compact states (New Jersey, Connecticut, and South Carolina). The Company operates the site under a license granted by the State of South Carolina. In order to fund the site closure obligation, the State of South Carolina has required the Company to establish a trust fund to cover such costs. At December 31, 2002 and 2001, the trust fund held cash and securities of $19,693 and $18,640, respectively. Under the terms of the Act, the Company's obligation to D&D the Barnwell site is effectively limited to the amount in the trust fund. Accordingly, the Company has recorded a D&D liability for the same amount as the balance in the trust fund.

(c) Other Buildings and Equipment

        The Company owns several buildings located in South Carolina and certain waste treatment equipment located at various commercial nuclear utilities throughout the United States that will require remediation at the end of their useful lives. The Company estimates the cost to remediate the buildings and equipment to be approximately $2,300. As of December 31, 2002 and 2001, the Company's D&D recorded liability was $2,008 and $1,813, respectively. The State of South Carolina has required the Company to post a letter of credit and surety bond with respect to the estimated remediation costs of $1,521 for the buildings.

        In June 2001, the FASB issued SFAS No. 143, Accounting for Asset Retirement Obligations. SFAS No. 143 requires the Company to record the fair value of an asset retirement obligation ("ARO") as a liability in the period in which it incurs a legal obligation associated with the retirement of tangible long-lived assets that result from the acquisition, construction, development and/or normal use of the assets. The Company is also required to record a corresponding asset that is depreciated over the life of the asset. Subsequent to the initial measurement of the ARO, the ARO will be adjusted at the end of each period to reflect the passage of time and changes in the estimated future cash flows underlying the obligation. The Company adopted SFAS No. 143 on January 1, 2003, as required, and recognized the following changes to the Company's consolidated financial statements: increase property, plant and equipment by $5,553 and increase facility and equipment D&D liabilities by $9,473. The pre-tax difference of $3,920 ($2,352 after tax) was recognized as a cumulative effect of a change in accounting principle in the Company's first quarter results.

        Management updates its D&D estimates on an annual basis. These estimates are based on current technology, regulations, and burial rates. Management is unable to reasonably estimate the impact that changes in technology, regulations, and burial rates will have on the ultimate costs. Changes in these factors could have a material impact on these estimates.

43

(10) 8% Cumulative Convertible Redeemable Preferred Stock

        In January 1995, the Company issued 160,000 shares of 8% Cumulative Convertible Redeemable Preferred Stock, par value $.01 per share (the "Convertible Preferred Stock") and an option (the "Carlyle Option") to purchase up to an additional 1,250,000 shares of the Company's common stock, at any time prior to January 24, 1999 for $3.75 per share to investment partnerships sponsored and controlled by The Carlyle Group ("Carlyle") for $16,000. During 1998, Carlyle exercised its option to purchase 1,206,809 shares of common stock for $4,526. The Convertible Preferred Stock is initially convertible into the Company's common stock at a conversion price of $3.00 per share and, if not previously converted, the Company is required to redeem the outstanding Convertible Preferred Stock on February 5, 2004 for $100 per share plus accrued and unpaid dividends, unless such date is extended with the approval of the holders of the Convertible Preferred Stock. Subject to restrictions in the Bank Credit Facility, the Company is required to pay quarterly dividends on the Convertible Preferred Stock (see note 6). As of December 31, 2002 and 2001, the Company had accrued dividends of $2,520 and $1,260, which are included in other noncurrent liabilities on the consolidated balance sheet. During 2000, holders converted 2,475 shares of Convertible Preferred Stock into 82,500 shares of common stock.

        The proceeds, net of offering expenses of $1,310, from the issuance of the Convertible Preferred Stock and Carlyle Option were $14,690, of which $14,410 was allocated to the Convertible Preferred Stock and $280 was allocated to the fair value of the Carlyle Option. The difference between the carrying value of the Convertible Preferred Stock and the redemption value has been accreted through charges to stockholders' equity.

        The estimated fair value of the Convertible Preferred Stock at December 31, 2002 approximated its carrying value.

(11) Stock Compensation

(a) Stock Option Plan

        In May 2000, the Company's stockholders approved the 1999 Stock Option and Incentive Plan (the "Plan") which authorizes a committee of the Board of Directors to grant various types of incentive awards (including incentive stock options, non-qualified options, stock appreciation rights, restricted shares, and performance units on shares) to directors, officers, and employees of the Company for issuance of up to 5,000,000 shares of common stock in the aggregate. At December 31, 2002, there were 3,442,470 additional shares available for grant under the Plan. The Company granted options in 1999 and prior years pursuant to the 1984 Stock Option Plan. No further grants will be made under this plan. At December 31, 2002, the Company had 3,442,470 shares reserved for grants of stock options and 1,983,239 outstanding.

44

        Changes in options outstanding are as follows:

	Weighted average exercise price		Number of shares
December 31, 1999	$	7.91	816,800
Granted		7.94	552,600
Exercised		5.88	(875	)
Terminated and expired		9.76	(65,875	)
December 31, 2000		7.82	1,302,650
Granted		4.02	310,000
Exercised		5.65	(12,500	)
Terminated and expired		12.91	(77,000	)
December 31, 2001		6.81	1,523,150
Granted		4.41	537,000
Exercised		5.75	(57,411	)
Terminated and expired		6.30	(19,500	)
December 31, 2002	$	6.19	1,983,239

        The following table summarizes information about outstanding and exercisable options at December 31, 2002:

Outstanding				Exercisable
Range of exercise price	Number outstanding	Weighted average remaining contractual life	Weighted average exercise price	Number exercisable	Weighted average exercise price
$  3.92 – $  5.88	1,341,439	7.58 years	$  4.81	500,263	$  5.53
$  8.13 – $  8.75	445,000	7.43 years	$  8.44	179,800	$  8.44
$10.13 – $10.63	196,800	4.89 years	$10.52	196,800	$10.52
	1,983,239			876,863

        Certain options issued in 2000, granted to executive officers of the Company, have exercise prices that were less than the fair value of the Company's common stock on the date of grant. The difference of $269 has been recorded as deferred compensation and is being recognized over the vesting period. During the years ended December 31, 2002, 2001, and 2000, the Company recognized compensation expense of $54, $54, and $108, respectively.

(b) Restricted Stock Units

        Upon approval of the Plan by the stockholders in May 2000, two of the Company's senior executives were granted 157,930 restricted stock units. The units vest over a four-year period. Upon vesting, the executive has the right to receive common stock in exchange for such units. The Company has accounted for this plan as a compensatory fixed plan under APB Opinion No. 25, which resulted in a compensation charge of approximately $1,323 of which $264, $264, and $529 were recognized during the years ended December 31, 2002, 2001, and 2000, respectively.

45

(12) Income Taxes

        The provision (benefit) for income taxes for the years ended December 31 consists of the following:

		2002		2001			2000
Current:
	State	$	691	$	457		$	624

        The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities at December 31, 2002 and 2001 are presented below:

			2002			2001
Deferred tax assets:
	Accounts and notes receivable principally due to allowance for doubtful accounts		$	764		$	650
	Waste processing and disposal liabilities			118			1,762

	Net operating loss carryforwards			1,794			6,161
	Alternative minimum tax credit carryforwards			2,303			418

				7,961			11,522

		Net deferred tax assets		7,489			10,868
Deferred tax liabilities:
	Plant, equipment, and intangibles principally due to differences in depreciation and amortization			(7,970	)		(6,311	)
	Net deferred tax assets (liabilities)		$	(481	)	$	4,557

        In assessing the realizability of deferred tax assets, management considered whether it was more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of the deferred tax assets is dependent upon the generation of future taxable income during periods in which temporary differences become deductible. Management considered income taxes paid during the previous two years and projected future taxable income in making this assessment. Based upon the level of historical taxable income and projections for future taxable income over the periods in which the temporary differences are deductible, management has deemed a valuation allowance of $472 and $654 as necessary at December 31, 2002 and 2001, respectively. During 2002, the Company decreased its valuation allowance by $182.

        The Company paid income taxes of $5,144, $1,382, and $5,052 in the years ended December 31, 2002, 2001, and 2000, respectively.

(13) Business Acquisition

        On June 8, 2000, the Company acquired the nuclear services business of Waste Management, Inc. ("WMI") through the purchase of all the outstanding capital stock of Waste Management Federal Services, Inc. ("WMFS") from Rust International, Inc. ("Rust") and all of the outstanding membership interests of Chem-Nuclear Systems, LLC ("Chem-Nuclear") from Chemical Waste Management, Inc. ("CWM") and CNS Holdings, Inc. ("CNS") for $68,758 in cash including $2,008 of transaction costs. The acquisition was accounted for under the purchase method of accounting. The aggregate purchase price in excess of the estimated fair value of tangible assets and identifiable intangible assets of $50,916 was allocated to goodwill. Operations of Waste Management Nuclear Services since June 8, 2000 are included in the Company's consolidated statements of operations.

(14) Short Term Borrowings

        Under the terms of the June 8, 2000 purchase agreement between the Company and WMI, WMI provided short-term project financing at a fixed rate of 9.0% to the Company for the design and construction phase of a project, which was completed in March 2002. In 2002, the Company repaid all

47

of the borrowings, plus accrued interest, with cash generated from the project. As of December 31, 2001, borrowings outstanding were $7,763.

(15) Profit Investment Plan

        The Company maintains a Profit Investment Plan for employees. The Profit Investment Plan permits pre-tax contributions to the Profit Investment Plan by participants pursuant to Section 401(k) of the Internal Revenue Code of 1% to 14% of base compensation. The Company matches 25% of the participants' eligible contributions based on a formula set forth in the Profit Investment Plan and may make additional matching contributions. Employer contributions vest at a rate of 20% per year of service. The Company's matching contributions were $1,247, $1,186 and $953 for the years ended December 31, 2002, 2001, and 2000, respectively.

(16) Related Party Transactions

        At December 31, 2002 and 2001, two of the Company's executive officers held loans of $672 and $735, respectively. The loans bear interest at 5% and are due December 31, 2009. These loans are included in other noncurrent assets in the accompanying consolidated balance sheets.

        In 2000, BNFL, Inc. ("BNFL") was considered a related party due to the convertible feature of a $10,000 convertible debenture with BNFL. This debenture expired in November 2000. The Company recognized revenues of approximately $22,000 in 2000, under subcontracts with BNFL related to their work performed on the DOE's Hanford River Protection and Idaho Advanced Mixed Waste Treatment Projects.

        On June 22, 2001, the Company filed suit against BNFL in the Circuit Court for Fairfax County, Virginia alleging that BNFL breached a Settlement Agreement dated April 20, 2001, under which BNFL was to make a $3,000 payment to the Company on or before May 28, 2001. On July 11, 2001, BNFL sued the Company in the Circuit Court for Howard County, Maryland alleging that "acts of default" had occurred under a $10,000 debenture issued by the Company to BNFL on November 7, 1995, therefore accelerating the Company's obligation to repay the debenture. The Company counterclaimed in the amount of $3,800, unrelated to the Company's claims in its lawsuit against BNFL. Additionally, on August 16, 2001, the Company filed a demand for binding arbitration against BNFL with the American Arbitration Association concerning certain claims against BNFL arising out of various contracts and agreements with BNFL.

        On December 12, 2001, the Company entered into a Settlement and Mutual Release Agreement with BNFL providing for the dismissal of litigation and arbitration between the two companies that began in June 2001. In order to resolve their differences without further resort to litigation or arbitration, BNFL transferred to the Company a net payment of $1,250, which represented a $14,394 payment by BNFL to the Company less a $13,144 payment by the Company to BNFL. The parties agreed to file consent motions and proposed orders asking for the dismissal of the lawsuits and arbitration with prejudice, except for certain issues related to the question of indemnification with respect to an alleged patent infringement matter. As part of the settlement and in consideration of the payment referred to above, the $10,000 debenture issued by the Company to BNFL was cancelled.

(17) Segment Reporting and Business Concentrations

        The Company has three primary segments: (i) Federal Services, (ii) Commercial Services, and (iii) Commercial Processing and Disposal. The following is a brief description of each of the segments:

(a) Federal Services ("FS")

        FS provides on-site waste processing and disposal services, off-site waste disposition, on-site management of nuclear facility operations, and on-site clean up (remedial action) services on large government projects for the Department of Energy ("DOE") and other governmental entities. The Company's services include program development, project management, nuclear facility operation, waste characterization, packaging and shipping of waste, selected technical services, and site cleanup.

(b) Commercial Services ("CS")

Intercompany revenues have been eliminated in the Federal Services and Commercial Services segments. Revenues by segment represents revenues earned based on third party billings to customers.

50

(d) Business Concentrations

        The Company's revenues are derived primarily from subcontracts and utility companies through a combination of DOE contractors and subcontractors. During the years ended December 31, 2002, 2001 and 2000, revenues from DOE contractors and subcontractors represented approximately 50%, 44%, and 44% of consolidated revenues, respectively. No commercial customer represented more than 10% of consolidated revenues for the years ended December 31, 2002, 2001, and 2000.

        Accounts receivable and costs and estimated earnings in excess of billing on uncompleted contracts relating to DOE contractors and subcontractors amounted to $8,900 and $6,539 at December 31, 2002 and $17,544 and $18,792 at December 31, 2001, respectively.

        The CPD segment is primarily reliant upon a single provider for its burial services for both customer and secondary waste disposal.

(18) Commitments and Contingencies

(a) Leases

        The Company has several noncancellable leases which cover real property, machinery and equipment, and certain manufacturing facilities. Such leases expire at various dates with, in some cases, options to extend their terms. Several of the leases contain provisions for rent escalation based primarily on increases in real estate taxes and through operating costs incurred by the lessor. Rent expense was $3,588, $5,715, and $5,338 for the years ended December 31, 2002, 2001, and 2000, respectively. The Company has certain capital leases for equipment.

        The following is a schedule of future minimum annual lease payments for all operating and capital leases with initial or remaining lease terms greater than one year at December 31, 2002:

		Operating		Capital
2003		$	3,348	$	349
2004			2,670		160
2005			1,930		126
2006			805		59
2007			115		—
Thereafter			1		—
	Future minimum lease payments	$	8,869		694
Less: portion representing interest					63
Less: current portion of capital lease obligation					315
	Long-term portion of capital lease obligation			$	316

        The long-term portion of capital lease obligation is included in other noncurrent liabilities in the accompanying consolidated balance sheets.

(b) Financial Insurance Instruments

        The Company is required to post from time to time financial assurance instruments to meet contractual obligations. In addition, the Company has entered into certain indemnification agreements with the providers of the surety instruments, which would require funding if the Company failed to perform under the contracts being insured and the Surety bond issuer was obligated to make payment to the insured parties. As of December 31, 2002, the Company had

51

outstanding assurance instruments of $16,831, which expire at the respective contract completion dates, and is not in default or material breach of any contract that requires the financial assurance.

(c) Legal Proceedings

        In May 2000, Toxgon Corporation ("Toxgon") filed a complaint for patent infringement against BNFL, Inc. ("BNFL") and the Company in the U.S. District Court for the Eastern District of Washington. In the complaint, Toxgon alleged, among other things, that BNFL and the Company infringed the claims of one of its U.S. patents. In August 2000, BNFL and the Company, in lieu of filing an answer, filed a motion to dismiss Toxgon's complaint for lack of subject matter jurisdiction. In September 2002, the District Court granted BNFL's and the Company's motion to dismiss.

        Toxgon filed a Notice of Appeal in the Ninth Circuit in October 2000. The issue on appeal was whether the District Court erred in dismissing the case for lack of subject matter jurisdiction. The Ninth Circuit transferred the case to the United States Court of Appeals for the Federal Circuit ("CAFC") in March 2002. In December 2002, the CAFC vacated the District Court's dismissal for lack of subject matter jurisdiction and remanded the action to the District Court for further proceedings. Toxgon filed an amended complaint in the District Court in November 2002, prior to the decision from the CAFC. The Company's answer to the amended complaint was filed on January 30, 2003. The Company believes that Toxgon's claims are frivolous and without merit.

        On June 22, 2001, the Company and two of its executive officers were sued in Federal District Court in Baltimore, Maryland by an individual stockholder on behalf of himself and other similarly situated stockholders of the Company. The putative class action suit alleges that certain statements and information included in the Company's press releases and in the periodic reports filed by it with the Securities and Exchange Commission contained materially false and misleading information in violation of the Federal securities laws. The Company filed a motion to dismiss the complaint. In response, the plaintiff filed an amended complaint which mooted the Company's motion to dismiss. The Company then filed a motion to dismiss the amended complaint, which the plaintiff opposed. In orders dated April 26, 2002, the District Court granted the motion to dismiss in its entirety and entered judgment in favor of the Company and the executive officers. On or about May 24, 2002, the plaintiff filed a notice of appeal. The appeal is currently pending in the United States Court of Appeals for the Fourth Circuit. The parties have completed their briefing and oral arguments are expected to be heard in May 2003.

        On December 2, 1999, the Company's wholly owned subsidiary, Scientific Ecology Group, Inc. ("SEG") (now named Duratek Services, Inc.), was named as a defendant in an adversary proceeding in the United States Bankruptcy Court for the District of Massachusetts. The Chapter 11 Trustee, on behalf of the debtor Molten Metal Technology, Inc. ("MMT") and its creditors, filed an adversary "Complaint to Avoid Fraudulent Transfer" naming as defendants Viacom Inc., the successor to CBS Corporation and Westinghouse Electric Corporation ("Westinghouse"), and SEG. The complaint alleges that the sale of Westinghouse's interest in a joint venture to MMT resulted in a fraudulent conveyance. The primary allegations against SEG are that MMT's release of SEG from obligations to pay $8 million to equalize capital expenditures and additional amounts for MMT's share of profits, and MMT's assumption of at least $1.5 million of SEG's liabilities, are avoidable because MMT did not receive reasonably equivalent value for the transfers. The complaint purports to state four bankruptcy and five common law counts. The Company intends to vigorously contest MMT's allegations on the basis that MMT did in fact receive reasonably equivalent value for its transfers. In addition, the Company may have a right of indemnification from Westinghouse pursuant to the relevant purchase agreement. It is too early in the litigation to provide an accurate assessment of the Company's liability, if any. Westinghouse has agreed to assume all litigation costs associated with the defense of the case, but has reserved the right to

52

challenge the Company's claim for indemnification for any settlement or judgment that may arise from the case. Westinghouse has moved to dismiss the complaint filed by the Chapter 11 Trustee. While Westinghouse's motion to dismiss was pending, the Chapter 11 Trustee sought to amend its complaint and that motion was granted. After the amended complaint was filed, Westinghouse filed a motion to dismiss the common law counts and the Court granted that motion.

        In addition, from time to time, the Company is a party to litigation or administrative proceedings relating to claims arising from its operations in the normal course of business. Management of the Company, on the advice of counsel, believes that the ultimate resolution of such litigation or administrative proceedings currently pending against the Company is unlikely, either individually or in the aggregate, to have a material adverse effect on the Company's results of operations or financial condition.

REVOLVING CREDIT FACILITY

        SECTION 2.1Revolving Credit Loans.     Subject to the terms and conditions of this Agreement, each Lender severally agrees to make Revolving Credit Loans to the Borrowers on a joint and several basis from time to time from the Closing Date through the Revolving Credit Maturity Date as requested by the Company on behalf of the Borrowers in accordance with the terms of Section 2.3; provided, that (a) each Lender's Revolving Credit Commitment Percentage of the sum of the aggregate amount of all outstanding Revolving Credit Loans, Swingline Loans and L/C Obligations shall at no time exceed such Lender's Revolving Credit Commitment and (b) no borrowing of Revolving Credit Loans shall be made if, immediately after giving effect thereto, the aggregate principal amount of Revolving Credit Loans then outstanding plus (i) all outstanding Swingline Loans plus (ii) the aggregate principal amount of all outstanding L/C Obligations would exceed the then applicable Borrowing Limit. Each Revolving Credit Loan by a Lender shall be in a principal amount equal to such Lender's Revolving Credit Commitment Percentage of the aggregate principal amount of Revolving Credit Loans requested on such occasion. Subject to the terms and conditions hereof, the Borrowers may borrow, repay and reborrow Revolving Credit Loans hereunder until the Revolving Credit Maturity Date.

        SECTION 2.2Swingline Loans.     

        (a)Availability.    Subject to the terms and conditions of this Agreement, the Swingline Lender agrees to make Swingline Loans to the Borrowers from time to time from the Closing Date through, but not including, the Swingline Termination Date; provided, that the Swingline Lender shall have no obligation to make any Swingline Loan, if, after giving effect to any amount requested, (a) the aggregate principal amount of all Swingline Loans then outstanding would exceed the Swingline Commitment or (b) the aggregate principal amount of all Revolving Credit Loans then outstanding plus the aggregate principal amount of all Swingline Loans then outstanding plus the L/C Obligations then outstanding would exceed the then applicable Borrowing Limit.

        (b)Refunding.    

        (i)    If not earlier repaid by the Borrowers, Swingline Loans shall be refunded by the Lenders on demand by the Swingline Lender. Such refundings shall be made by the Lenders in accordance with their respective Revolving Credit Commitment Percentages and shall thereafter be reflected as Revolving Credit Loans of the Lenders on the books and records of the Administrative Agent. Each Lender shall fund its respective Revolving Credit Commitment Percentage of Revolving Credit Loans as required to repay Swingline Loans outstanding to the Swingline Lender upon demand by the Swingline Lender but in no event later than 2:00 p.m. (Charlotte time) on the next succeeding Business Day after such demand is made. No Lender's obligation to fund its respective Revolving Credit Commitment Percentage of a Swingline Loan shall be affected by any other Lender's failure to fund its Revolving Credit Commitment Percentage of a Swingline Loan, nor shall any Lender's Revolving Credit Commitment Percentage be increased as a result of any such

19

failure of any other Lender to fund its Revolving Credit Commitment Percentage of a Swingline Loan.

        (ii)  The Borrowers shall pay to the Swingline Lender on demand the amount of such Swingline Loans to the extent amounts received from the Lenders pursuant to Section 2.2(b)(i) are not sufficient to repay in full the outstanding Swingline Loans requested or required to be refunded. In addition, each Borrower hereby authorizes the Administrative Agent to charge any account maintained with the Swingline Lender (up to the amount available therein) in order to immediately pay the Swingline Lender the amount of such Swingline Loans to the extent amounts received from the Lenders are not sufficient to repay in full the outstanding Swingline Loans requested or required to be refunded. If any portion of any such amount paid to the Swingline Lender shall be recovered by or on behalf of the Borrowers from the Swingline Lender in bankruptcy or otherwise, the loss of the amount so recovered shall be ratably shared among all the Lenders in accordance with their respective Revolving Credit Commitment Percentages (unless the amounts so recovered by or on behalf of the Borrowers pertain to a Swingline Loan extended after the occurrence and during the continuance of an Event of Default of which the Administrative Agent has received actual notice and which such Event of Default has not been waived by the Required Lenders or the Lenders, as applicable).

        (iii)    Each Lender acknowledges and agrees that its obligation to refund Swingline Loans in accordance with the terms of this Section 2.2 is absolute and unconditional and shall not be affected by any circumstance whatsoever, including, without limitation, non-satisfaction of the conditions set forth in Article VI. Further, each Lender agrees and acknowledges that if prior to the refunding of any outstanding Swingline Loans pursuant to this Section 2.2, one of the events described in Section 12.1(j) or (k) shall have occurred, each Lender will, on the date the applicable Revolving Credit Loan would have been made, purchase an undivided participating interest in the Swingline Loan to be refunded in an amount equal to its Revolving Credit Commitment Percentage of the aggregate amount of such Swingline Loan. Each Lender will immediately transfer to the Swingline Lender, in immediately available funds, the amount of its participation and upon receipt thereof the Swingline Lender will deliver to such Lender a certificate evidencing such participation dated the date of receipt of such funds and for such amount. Whenever, at any time after the Swingline Lender has received from any Lender such Lender's participating interest in a Swingline Loan, the Swingline Lender receives any payment on account thereof, the Swingline Lender will distribute to such Lender its participating interest in such amount (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender's participating interest was outstanding and funded).

References herein to "issue" and derivations thereof with respect to Letters of Credit shall also include extensions or modifications of any Existing Letters of Credit, unless the context otherwise requires.

        SECTION 3.2Procedure for Issuance of Letters of Credit.     The Borrowers may from time to time request that the Issuing Lender issue a Letter of Credit by delivering to the Issuing Lender at the Administrative Agent's Office an Application therefor, completed to the satisfaction of the Issuing Lender, and such other certificates, documents and other papers and information as the Issuing Lender may request. Upon receipt of any Application, the Issuing Lender shall process such Application and the certificates, documents and other papers and information delivered to it in connection therewith in accordance with its customary procedures and shall, subject to Section 3.1 and Article VI hereof, promptly issue the Letter of Credit requested thereby (but in no event shall the Issuing Lender be

23

required to issue any Letter of Credit earlier than three (3) Business Days after its receipt of the Application therefor and all such other certificates, documents and other papers and information relating thereto) by issuing the original of such Letter of Credit to the beneficiary thereof or as otherwise may be agreed by the Issuing Lender and the Borrowers. The Issuing Lender shall promptly furnish to the Borrowers a copy of such Letter of Credit and promptly notify each Lender of the issuance and upon request by any Lender, furnish to such Lender a copy of such Letter of Credit and the amount of such Lender's L/C Participation therein.

        (c)  The Borrowers shall also pay all normal costs and expenses of the Issuing Lender in connection with the issuance, transfer or other administration of the Letters of Credit.

        (d)  The Administrative Agent shall, promptly following its receipt thereof, distribute to the Issuing Lender and the L/C Participants all commissions received by the Administrative Agent in accordance with their respective Revolving Credit Commitment Percentages.

        SECTION 3.4L/C Participations.

Each L/C Participant unconditionally and irrevocably agrees with the Issuing Lender that, if a draft is paid under any Letter of Credit for which the Issuing Lender is not reimbursed in full by the Borrowers in accordance with the terms of this Agreement, such L/C Participant shall pay to the Issuing Lender upon demand at the Issuing Lender's address for notices specified herein an amount equal to such L/C Participant's Revolving Credit Commitment Percentage of the amount of such draft, or any part thereof, which is not so reimbursed.

        (b)  Upon becoming aware of any amount required to be paid by any L/C Participant to the Issuing Lender pursuant to Section 3.4(a) in respect of any unreimbursed portion of any payment made by the Issuing Lender under any Letter of Credit, the Issuing Lender shall notify each L/C Participant of the amount and due date of such required payment and such L/C Participant shall pay to the Issuing Lender the amount specified on the applicable due date. If any such amount is paid to the Issuing Lender after the date such payment is due, such L/C Participant shall pay to the Issuing Lender on demand, in addition to such amount, the product of (i) such amount, times (ii) the daily average Federal Funds Rate as determined by the Administrative Agent during the period from and including the date such payment is due to the date on which such payment is immediately available to the Issuing Lender, times (iii) a fraction the numerator of which is the number of days that elapse during such period and the denominator of which is 360. A certificate of the Issuing Lender with respect to any

24

amounts owing under this Section 3.4(b) shall be conclusive in the absence of manifest error. With respect to payment to the Issuing Lender of the unreimbursed amounts described in this Section 3.4(b), if the L/C Participants receive notice that any such payment is due (A) prior to 1:00 p.m. (Charlotte time) on any Business Day, such payment shall be due that Business Day, and (B) after 1:00 p.m. (Charlotte time) on any Business Day, such payment shall be due on the following Business Day.

        (c)  Whenever, at any time after the Issuing Lender has made payment under any Letter of Credit and has received from any L/C Participant its Revolving Credit Commitment Percentage of such payment in accordance with this Section 3.4, the Issuing Lender receives any payment related to such Letter of Credit (whether directly from any Borrower or otherwise), or any payment of interest on account thereof, the Issuing Lender will distribute to such L/C Participant its pro rata share thereof; provided, that in the event that any such payment received by the Issuing Lender shall be required to be returned by the Issuing Lender, such L/C Participant shall return to the Issuing Lender the portion thereof previously distributed by the Issuing Lender to it.

        SECTION 3.5Reimbursement Obligation of the Borrowers.     In the event of any drawing under any Letter of Credit, the Borrowers jointly and severally agree to reimburse (either with the proceeds of a Revolving Credit Loan as provided for in this Section 3.5 or with funds from other sources), in same day funds, the Issuing Lender on each date on which the Issuing Lender notifies the Borrowers of the date and amount of a draft paid under any Letter of Credit for the amount of (a) such draft so paid and (b) any amounts referred to in Section 3.3(c) incurred by the Issuing Lender in connection with such payment. Unless the Borrowers shall immediately notify the Issuing Lender that the Borrowers intend to reimburse the Issuing Lender for such drawing from other sources or funds, the Borrowers shall be deemed to have timely given a Notice of Revolving Credit/Swingline Borrowing to the Administrative Agent requesting that the Lenders make a Revolving Credit Loan bearing interest at the Base Rate on such date in the amount of (a) such draft so paid and (b) any amounts referred to in Section 3.3(c) incurred by the Issuing Lender in connection with such payment, and the Lenders shall make a Revolving Credit Loan bearing interest at the Base Rate in such amount, the proceeds of which shall be applied to reimburse the Issuing Lender for the amount of the related drawing and costs and expenses. Each Lender acknowledges and agrees that its obligation to fund a Revolving Credit Loan in accordance with this Section 3.5 to reimburse the Issuing Lender for any draft paid under a Letter of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including, without limitation, non-satisfaction of the conditions set forth in Section 2.3(a) or Article VI. If the Borrowers have elected to pay the amount of such drawing with funds from other sources and shall fail to reimburse the Issuing Lender as provided above, the unreimbursed amount of such drawing shall bear interest at the rate which would be payable on any outstanding Base Rate Loans which were then overdue from the date such amounts become payable (whether at stated maturity, by acceleration or otherwise) until payment in full.

        SECTION 3.6Obligations Absolute.     The obligations of the Borrowers under this Article III (including without limitation the Reimbursement Obligation) shall be irrevocable, absolute and unconditional under any and all circumstances and irrespective of any set-off, counterclaim or defense to payment which the Borrowers may have or have had against the Issuing Lender or any beneficiary of a Letter of Credit. The Borrowers also agree with the Issuing Lender that the Issuing Lender and the L/C Participants shall not be responsible for, and the Reimbursement Obligation of the Borrowers under Section 3.5 shall not be affected by, among other things, the validity or genuineness of this Agreement, any documents or of any endorsements thereon, even though such documents shall in fact prove to be invalid, fraudulent or forged, or any dispute between or among the Borrowers and any beneficiary of any Letter of Credit or any other party to which such Letter of Credit may be transferred or any claims whatsoever of a Borrower against any beneficiary of such Letter of Credit or any such transferee or the application or misapplication of the proceeds or any Letter of Credit by any beneficiary thereunder. The Issuing Lender shall not be liable for any error, omission, interruption or

25

delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Letter of Credit, except for errors or omissions caused by the Issuing Lender's gross negligence or willful misconduct. The Borrowers agree that any action taken or omitted by the Issuing Lender under or in connection with any Letter of Credit or the related drafts or documents, if done in the absence of gross negligence or willful misconduct and in accordance with the standards of care specified in the Uniform Customs and, to the extent not inconsistent therewith, the UCC as in effect in the State of New York from time to time shall be binding on the Borrowers and shall not result in any liability of the Issuing Lender or any L/C Participant to the Borrowers. The responsibility of the Issuing Lender to the Borrowers in connection with any draft presented for payment under any Letter of Credit shall, in addition to any payment obligation expressly provided for in such Letter of Credit, be limited to determining that the documents (including each draft) delivered under such Letter of Credit in connection with such presentment are in conformity with such Letter of Credit.

        SECTION 3.7Effect of Application.     To the extent that any provision of any Application related to any Letter of Credit is inconsistent with the provisions of this Article III, the provisions of this Article III shall apply.

GENERAL LOAN PROVISIONS

        SECTION 5.1Interest.     

        (a)Interest Rate Options.    Subject to the provisions of this Section 5.1, at the election of the Company on behalf of the Borrowers, the aggregate principal balance of any Revolving Credit Note and any Term Loan Note shall bear interest at (i) the Base Rate plus the Applicable Margin as set forth in Section 5.1(c) or (ii) the LIBOR Rate plus the Applicable Margin as set forth in Section 5.1(c); provided that the LIBOR Rate shall not be available until three (3) Business Days after the Closing Date. The Swingline Note shall bear interest at the Base Rate plus the Applicable Margin as set forth in Section 5.1(c). The Borrowers shall select the rate of interest and Interest Period, if any, applicable to any Loan at the time a Notice of Revolving Credit/Swingline Borrowing is given pursuant to Section 2.3(a) or a Notice of Term Loan Borrowing is given pursuant to Section 4.2 or at the time a Notice of Conversion/Continuation is given pursuant to Section 5.2. Each Loan or portion thereof bearing interest based on the Base Rate (other than Swingline Loans) shall be a "Base Rate Loan", each Loan or portion thereof bearing interest based on the LIBOR Rate shall be a "LIBOR Rate Loan." Any Loan or any portion thereof as to which the Borrowers have not duly specified an interest rate as provided herein shall be deemed a Base Rate Loan.

        (b)Interest Periods.    In connection with each LIBOR Rate Loan, the Company on behalf of the Borrowers, by giving notice at the times described in Section 5.1(a), shall elect an interest period (each, an "Interest Period") to be applicable to such LIBOR Rate Loan, which Interest Period shall be a period of one (1), two (2), three (3), or six (6) months with respect to each LIBOR Rate Loan; provided that:

        (i)    the Interest Period shall commence on the date of advance of or conversion to any LIBOR Rate Loan and, in the case of immediately successive Interest Periods, each successive Interest Period shall commence on the date on which the next preceding Interest Period expires;

        (ii)  if any Interest Period would otherwise expire on a day that is not a Business Day, such Interest Period shall expire on the next succeeding Business Day; provided, that if any Interest Period with respect to a LIBOR Rate Loan would otherwise expire on a day that is not a Business Day but is a day of the month after which no further Business Day occurs in such month, such Interest Period shall expire on the next preceding Business Day;

29

        (iii)  any Interest Period with respect to a LIBOR Rate Loan that begins on the last Business Day of a calendar month (or on a day for which there is no numerically corresponding day in the calendar month at the end of such Interest Period) shall end on the last Business Day of the relevant calendar month at the end of such Interest Period;

        (iv)  no Interest Period shall extend beyond the Revolving Credit Termination Date, the Term A Loan Maturity Date or the Term B Loan Maturity Date, as applicable, and Interest Periods shall be selected by the Borrowers so as to permit the Borrowers to make mandatory reductions of the Revolving Credit Commitment pursuant to Section 2.6(b) and the quarterly principal installment payments pursuant to Section 4.3 without payment of any amounts pursuant to Section 5.9; and

        (v)  there shall be no more than seven (7) Interest Periods in effect at any time.

        (c)Applicable Margin.    The Applicable Margin provided for in Section 5.1(a) with respect to the Loans (the "Applicable Margin") shall be based upon the Leverage Ratio as set forth in the table below and shall be determined and adjusted quarterly on the date (each a "Calculation Date") ten (10) Business Days after the date by which the Borrowers are required to provide an Officer's Compliance Certificate for the most recently ended fiscal quarter of the Borrowers and their Subsidiaries; provided, that with respect to the period commencing on the Effective Date and ending on the next Calculation Date to occur after the Effective Date, the calculation of the Applicable Margin shall be based on the most recent Officer's Compliance Certificate received by the Administrative Agent and Lenders prior to the Effective Date. Notwithstanding the foregoing, if the Borrowers fail to provide the Officer's Compliance Certificate as required by Section 8.2 for the most recently ended fiscal quarter of the Borrowers and their Subsidiaries preceding the applicable Calculation Date, the Applicable Margin from such Calculation Date shall be based on Pricing Level 1 (as shown below) until such time as an appropriate Officer's Compliance Certificate is provided, at which time the Pricing Level shall be determined by reference to the Leverage Ratio as of the last day of the most recently ended fiscal quarter of the Borrowers preceding such Calculation Date. The Applicable Margin shall be effective from one Calculation Date until the next Calculation Date. Any adjustment in the Applicable Margin shall be applicable to all Extensions of Credit then existing or subsequently made or issued.

		Revolving Credit and Term A Loan Facilities Applicable Margin Per Annum		Term B Loan Facility Applicable Margin Per Annum
Level	Leverage Ratio	Base Rate +	LIBOR Rate +	Base Rate +	LIBOR Rate +
1	Greater than or equal to 3.00 to 1.00.	3.50%	4.50%	4.00%	5.00%

5	Less than 1.50 to 1.00.	1.75%	2.75%	2.25%	3.25%

        Notwithstanding the foregoing, the Leverage Ratios set forth in this Section 5.1(c) are for pricing purposes only and shall not be deemed to permit the Leverage Ratio to exceed the maximum amounts permitted under this Agreement. The Applicable Margins set forth in this Section 5.1(c) represent base pricing subject to increase as set forth in Section 5.1(d).

        (d)Default Rate.    Subject to Section 12.3, at the discretion of the Administrative Agent and Required Lenders upon the occurrence and during the continuance of an Event of Default, (i) the

30

Borrowers shall no longer have the option to request LIBOR Rate Loans or Swingline Loans, (ii) all outstanding LIBOR Rate Loans shall bear interest at a rate per annum two percent (2%) in excess of the rate then applicable to LIBOR Rate Loans, as applicable, until the end of the applicable Interest Period and thereafter at a rate equal to two percent (2%) in excess of the rate then applicable to Base Rate Loans (calculated at the highest Applicable Margin), and (iii) all outstanding Base Rate Loans and Swingline Loans shall bear interest at a rate per annum equal to two percent (2%) in excess of the rate then applicable to Base Rate Loans. Interest shall continue to accrue on the Notes after the filing by or against any Borrower of any petition seeking any relief in bankruptcy or under any act or law pertaining to insolvency or debtor relief, whether state, federal or foreign.

        (e)Interest Payment and Computation.    Interest on each Base Rate Loan and Swingline Loans shall be payable in arrears on the last Business Day of each calendar quarter commencing June 30, 2000; and interest on each LIBOR Rate Loan shall be payable on the last day of each Interest Period applicable thereto, and if such Interest Period extends over three (3) months, at the end of each three (3) month interval during such Interest Period. Interest on LIBOR Rate Loans and all fees payable hereunder shall be computed on the basis of a 360-day year and assessed for the actual number of days elapsed and interest on Base Rate Loans shall be computed on the basis of a 365/66-day year and assessed for the actual number of days elapsed.

        (f)Maximum Rate.    In no contingency or event whatsoever shall the aggregate of all amounts deemed interest hereunder or under any of the Notes charged or collected pursuant to the terms of this Agreement or pursuant to any of the Notes exceed the highest rate permissible under any Applicable Law which a court of competent jurisdiction shall, in a final determination, deem applicable hereto. In the event that such a court determines that the Lenders have charged or received interest hereunder in excess of the highest applicable rate, the rate in effect hereunder shall automatically be reduced to the maximum rate permitted by Applicable Law and the Lenders shall at the Administrative Agent's option (i) promptly refund to the Borrowers any interest received by Lenders in excess of the maximum lawful rate or (ii) shall apply such excess to the principal balance of the Obligations. It is the intent hereof that the Borrowers not pay or contract to pay, and that neither the Administrative Agent nor any Lender receive or contract to receive, directly or indirectly in any manner whatsoever, interest in excess of that which may be paid by the Borrowers under Applicable Law.

        SECTION 5.2Notice and Manner of Conversion or Continuation of Loans.     Provided that no Event of Default has occurred and is then continuing, the Borrowers shall have the option to convert at any time following the third Business Day after the Closing Date all or any portion of its outstanding Base Rate Loans (other than Swingline Loans) in a principal amount equal to $2,000,000 or any whole multiple of $500,000 in excess thereof into one or more LIBOR Rate Loans and (b) upon the expiration of any Interest Period, (i) convert all or any part of its outstanding LIBOR Rate Loans in a principal amount equal to $1,000,000 or a whole multiple of $250,000 in excess thereof into Base Rate Loans or (ii) continue such LIBOR Rate Loans as LIBOR Rate Loans. Whenever the Borrowers desire to convert or continue Loans as provided above, the Company on behalf of the Borrowers shall give the Administrative Agent irrevocable prior written notice in the form attached as Exhibit F (a "Notice of Conversion/Continuation") not later than 11:00 a.m. (Charlotte time) three (3) Business Days before the day on which a proposed conversion or continuation of such Loan is to be effective specifying (A) the Loans to be converted or continued, and, in the case of any LIBOR Rate Loan to be converted or continued, the last day of the Interest Period therefor specifying the Credit Facility to which such Loan relates, (B) the effective date of such conversion or continuation (which shall be a Business Day), (C) the principal amount of such Loans to be converted or continued, and (D) the Interest Period to be applicable to such converted or continued LIBOR Rate Loan.

Upon receipt by the Administrative Agent of each such payment, the Administrative Agent shall distribute to each Lender at its address for notices set forth herein its pro rata share of such payment in accordance with such Lender's Revolving Credit Commitment Percentage, Term A Loan Percentage and/or Term B Loan Percentage, as applicable (except as specified below) and shall wire advice of the amount of such credit to each Lender. Each payment to the Administrative Agent of the Issuing Lender's fees or L/C Participants' commissions shall be made in like manner, but for the account of the Issuing Lender or the L/C Participant, as the case may be.

        SECTION 5.5Crediting of Payments and Proceeds.     In the event that the Borrowers shall fail to pay any of the Obligations when due and the Obligations have been accelerated pursuant to Section 12.2, all payments received by the Lenders upon the Notes and the other Obligations and all net proceeds from the enforcement of the Obligations shall be applied first to all expenses then due and payable by the Borrowers hereunder, then to all indemnity obligations then due and payable by the Borrowers hereunder, then to all Administrative Agent's and Issuing Lender's fees then due and payable, then to all commitment and other fees and commissions then due and payable, then to accrued and unpaid interest on the Swingline Note to the Swingline Lender, then to the principal amount outstanding under the Swingline Note to the Swingline Lender, then to accrued and unpaid interest on the other Notes and the Reimbursement Obligation (pro rata in accordance with all such amounts due), then to the principal amount of the other Notes and Reimbursement Obligation and any termination payments due in respect of a Hedging Agreement with any Lender (which such Hedging Agreement is permitted hereunder and required or requested by the Required Lenders) (pro rata in accordance with all such amounts due) and then to the cash collateral account described in Section 12.2(b) hereof to the extent of any L/C Obligations then outstanding, then to any termination payments due in respect of a Hedging Agreement with any Lender (which such Hedging Agreement is permitted, but not required or requested by the Required Lenders), in that order.

        SECTION 5.6Adjustments.     If any Lender (a "Benefited Lender") shall at any time receive any payment of all or part of the Obligations owing to it, or interest thereon, or if any Lender shall at any time receive any collateral in respect of the Obligations owing to it (whether voluntarily or involuntarily, by set-off or otherwise) in a greater proportion than any such payment to and collateral received by any other Lender, if any, in respect of the Obligations owing to such other Lender, or interest thereon, such Benefited Lender shall purchase for cash from the other Lenders such portion of each such other Lender's Extensions of Credit, or shall provide such other Lenders with the benefits of any such collateral, or the proceeds thereof, as shall be necessary to cause such Benefited Lender to share the excess payment or benefits of such collateral or proceeds ratably with each of the Lenders; provided, that if all or any portion of such excess payment or benefits is thereafter recovered from such

33

Benefited Lender, such purchase shall be rescinded, and the purchase price and benefits returned to the extent of such recovery, but without interest. The Borrowers agree that each Lender so purchasing a portion of another Lender's Extensions of Credit may exercise all rights of payment (including, without limitation, rights of set-off) with respect to such portion as fully as if such Lender were the direct holder of such portion.

        SECTION 5.7Nature of Obligations of Lenders Regarding Extensions of Credit; Assumption by the Administrative Agent.     The obligations of the Lenders under this Agreement to make the Loans and issue or participate in Letters of Credit are several and are not joint or joint and several. Unless the Administrative Agent shall have received notice from a Lender prior to a proposed borrowing date that such Lender will not make available to the Administrative Agent such Lender's ratable portion of the amount to be borrowed on such date (which notice shall not release such Lender of its obligations hereunder), the Administrative Agent may assume that such Lender has made such portion available to the Administrative Agent on the proposed borrowing date in accordance with Sections 2.3(b) and 4.2, and the Administrative Agent may, in reliance upon such assumption, make available to the Borrowers on such date a corresponding amount. If such amount is made available to the Administrative Agent on a date after such borrowing date, such Lender shall pay to the Administrative Agent on demand an amount, until paid, equal to the product of (a) the amount not made available by such Lender in accordance with the terms hereof, times (b) the daily average Federal Funds Rate during such period as determined by the Administrative Agent, times (c) a fraction the numerator of which is the number of days that elapse from and including such borrowing date to the date on which such amount not made available by such Lender in accordance with the terms hereof shall have become immediately available to the Administrative Agent and the denominator of which is 360. A certificate of the Administrative Agent with respect to any amounts owing under this Section 5.7 shall be conclusive, absent manifest error. If such Lender's Revolving Credit Commitment Percentage, Term A Loan Percentage or Term B Loan Percentage, as applicable, of such borrowing is not made available to the Administrative Agent by such Lender within three (3) Business Days after such borrowing date, the Administrative Agent shall be entitled to recover such amount made available by the Administrative Agent with interest thereon at the rate per annum applicable to Base Rate Loans hereunder, on demand, from the Borrowers. The failure of any Lender to make its Revolving Credit Commitment Percentage, Term A Loan Percentage or Term B Loan Percentage, as applicable, of any Loan available shall not relieve it or any other Lender of its obligation, if any, hereunder to make its Revolving Credit Commitment Percentage, Term A Loan Percentage or Term B Loan Percentage, as applicable, of such Loan available on such borrowing date, but no Lender shall be responsible for the failure of any other Lender to make its Revolving Credit Commitment Percentage, Term A Loan Percentage or Term B Loan Percentage, as applicable, of such Loan available on the borrowing date.

        SECTION 5.8Changed Circumstances.     

        (a)Circumstances Affecting LIBOR Rate Availability.    If with respect to any Interest Period the Administrative Agent or any Lender (after consultation with Administrative Agent) shall determine that, by reason of circumstances affecting the foreign exchange and interbank markets generally, deposits in eurodollars, in the applicable amounts are not being quoted via Dow Jones Market Screen 3750 or offered to the Administrative Agent or such Lender for such Interest Period, then the Administrative Agent shall forthwith give notice thereof to the Borrowers. Thereafter, until the Administrative Agent notifies the Borrowers that such circumstances no longer exist, the obligation of the Lenders to make LIBOR Rate Loans and the right of the Borrowers to convert any Loan to or continue any Loan as a LIBOR Rate Loan shall be suspended, and the Borrowers shall repay in full (or cause to be repaid in full) the then outstanding principal amount of each such LIBOR Rate Loan together with accrued interest thereon, on the last day of the then current Interest Period applicable to such LIBOR Rate Loan or convert the then outstanding principal amount of each such LIBOR Rate Loan to a Base Rate Loan as of the last day of such Interest Period.

34

        (b)Laws Affecting LIBOR Rate Availability.    If, after the date hereof, the introduction of, or any change in, any Applicable Law or any change in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender (or any of their respective Lending Offices) with any request or directive (whether or not having the force of law) of any such Governmental Authority, central bank or comparable agency, shall make it unlawful or impossible for any of the Lenders (or any of their respective Lending Offices) to honor its obligations hereunder to make or maintain any LIBOR Rate Loan, such Lender shall promptly give notice thereof to the Administrative Agent and the Administrative Agent shall promptly give notice to the Borrowers and the other Lenders. Thereafter, until the Administrative Agent notifies the Borrowers that such circumstances no longer exist, (i) the obligations of the Lenders to make LIBOR Rate Loans and the right of the Borrowers to convert any Loan or continue any Loan as a LIBOR Rate Loan shall be suspended and thereafter the Borrowers may select only Base Rate Loans hereunder, and (ii) if any of the Lenders may not lawfully continue to maintain a LIBOR Rate Loan to the end of the then current Interest Period applicable thereto as a LIBOR Rate Loan, the applicable LIBOR Rate Loan shall immediately be converted to a Base Rate Loan for the remainder of such Interest Period.

        (c)Increased Costs.    If, after the date hereof, the introduction of, or any change in, any Applicable Law, or in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any of the Lenders (or any of their respective Lending Offices) with any request or directive (whether or not having the force of law) of such Governmental Authority, central bank or comparable agency:

        (i)    shall subject any of the Lenders (or any of their respective Lending Offices) to any tax, duty or other charge with respect to any Note, Letter of Credit or Application or shall change the basis of taxation of payments to any of the Lenders (or any of their respective Lending Offices) of the principal of or interest on any Note, Letter of Credit or Application or any other amounts due under this Agreement in respect thereof (except for changes in the rate of tax on the overall net income of any of the Lenders or any of their respective Lending Offices imposed by the jurisdiction in which such Lender is organized or is or should be qualified to do business or such Lending Office is located); or

        (ii)  shall impose, modify or deem applicable any reserve (including, without limitation, any imposed by the Board of Governors of the Federal Reserve System), special deposit, insurance or capital or similar requirement against assets of, deposits with or for the account of, or credit extended by any of the Lenders (or any of their respective Lending Offices) or shall impose on any of the Lenders (or any of their respective Lending Offices) or the foreign exchange and interbank markets any other condition affecting any Note; and the result of any of the foregoing is to increase the costs to any of the Lenders of maintaining any LIBOR Rate Loan or issuing or participating in Letters of Credit or to reduce the yield or amount of any sum received or receivable by any of the Lenders under this Agreement or under the Notes in respect of a LIBOR Rate Loan or Letter of Credit or Application, then such Lender shall promptly notify the Administrative Agent, and the Administrative Agent shall promptly notify the Borrowers of such fact and demand compensation therefor and, within fifteen (15) days after such notice by the Administrative Agent, the Borrowers shall pay to such Lender such additional amount or amounts as will compensate such Lender or Lenders for such increased cost or reduction. The Administrative Agent will promptly notify the Borrowers of any event of which it has knowledge which will entitle such Lender to compensation pursuant to this Section 5.8(c); provided, that the Administrative Agent shall incur no liability whatsoever to the Lenders or the Borrowers in the event it fails to do so. The amount of such compensation shall be determined, in the applicable Lender's sole discretion, based upon the assumption that such Lender funded its Revolving Credit

35

Commitment Percentage, Term A Loan Percentage or Term B Loan Percentage, as applicable, of the LIBOR Rate Loans in the London interbank market and using any reasonable attribution or averaging methods which such Lender deems appropriate and practical. A certificate of such Lender setting forth the basis for determining such amount or amounts necessary to compensate such Lender shall be forwarded to the Borrowers through the Administrative Agent and shall be conclusively presumed to be correct save for manifest error.

        SECTION 5.9Indemnity.     The Borrowers hereby indemnify each of the Lenders against any loss or expense which may arise or be attributable to each Lender's obtaining, liquidating or employing deposits or other funds acquired to effect, fund or maintain any Loan (a) as a consequence of any failure by the Borrowers to make any payment when due of any amount due hereunder in connection with a LIBOR Rate Loan, (b) due to any failure of the Borrowers to borrow on a date specified therefor in a Notice of Borrowing or Notice of Continuation/Conversion or make a prepayment after giving notice thereof to the Administrative Agent or (c) due to any payment, prepayment or conversion of any LIBOR Rate Loan on a date other than the last day of the Interest Period therefor. The amount of such loss or expense shall be determined, in the applicable Lender's sole discretion, based upon the assumption that such Lender funded its Revolving Credit Commitment Percentage, Term A Loan Percentage or Term B Loan Percentage, as applicable, of the LIBOR Rate Loans in the London interbank market and using any reasonable attribution or averaging methods which such Lender deems appropriate and practical. A certificate of such Lender setting forth the basis for determining such amount or amounts necessary to compensate such Lender shall be forwarded to the Borrowers through the Administrative Agent and shall be conclusively presumed to be correct save for manifest error.

        SECTION 5.10Capital Requirements.     If after the date hereof either (a) the introduction of, or any change in, or in the interpretation of, any Applicable Law or (b) compliance with any guideline or request from any central bank or comparable agency or other Governmental Authority (whether or not having the force of law), has or would have the effect of reducing the rate of return on the capital of, or has affected or would affect the amount of capital required to be maintained by, any Lender or any corporation controlling such Lender as a consequence of, or with reference to the Commitments and other commitments of this type, below the rate which the Lender or such other corporation could have achieved but for such introduction, change or compliance, then within five (5) Business Days after written demand by any such Lender, the Borrowers shall pay to such Lender from time to time as specified by such Lender additional amounts sufficient to compensate such Lender or other corporation for such reduction. A certificate as to such amounts submitted to the Borrowers and the Administrative Agent by such Lender, shall, in the absence of manifest error, be presumed to be correct and binding for all purposes.

        SECTION 5.11Taxes.     

        (a)Payments Free and Clear.    Any and all payments by the Borrowers hereunder or under the Notes or the Letters of Credit shall be made free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholding, and all liabilities with respect thereto excluding, (i) in the case of each Lender and the Administrative Agent, income and franchise taxes imposed by the jurisdiction under the laws of which such Lender or the Administrative Agent (as the case may be) is organized or is or should be qualified to do business or any political subdivision thereof, (ii) in the case of each Lender, income and franchise taxes imposed by the jurisdiction of such Lender's Lending Office or any political subdivision thereof and (iii) any United States federal income tax that is imposed on, or required to be deducted from, a payment hereunder (or under the Notes or Letters of Credit) by reason of a failure to comply with the requirements of Section 5.11(e) (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as "Taxes"). If the Borrowers shall be required by law to deduct or withhold any Taxes from or in respect of any sum payable hereunder or under any Note or Letter of Credit to any Lender or the Administrative Agent, (A) the sum payable shall be increased as may be

36

necessary so that after making all required deductions or withholdings (including deductions or withholdings applicable to additional sums payable under this Section 5.11) such Lender or the Administrative Agent (as the case may be) receives an amount equal to the amount such party would have received had no such deductions or withholdings been made, (B) the Borrowers shall make such deductions or withholdings, (C) the Borrowers shall pay the full amount deducted to the relevant taxing authority or other authority in accordance with applicable law, and (D) the Borrowers shall deliver to the Administrative Agent evidence of such payment to the relevant taxing authority or other Governmental Authority in the manner provided in Section 5.11(d).

        (b)Stamp and Other Taxes.    In addition, the Borrowers shall pay any present or future stamp, registration, recordation or documentary taxes or any other similar fees or charges or excise or property taxes, levies of the United States or any state or political subdivision thereof or any applicable foreign jurisdiction which arise from any payment made hereunder or from the execution, delivery or registration of, or otherwise with respect to, this Agreement, the Loans, the Letters of Credit, the other Loan Documents, or the perfection of any rights or security interest in respect thereto (hereinafter referred to as "Other Taxes").

        (c)Indemnity.    The Borrowers shall indemnify each Lender and the Administrative Agent for the full amount of Taxes and Other Taxes (including, without limitation, any Taxes and Other Taxes imposed by any jurisdiction on amounts payable under this Section 5.11) paid by such Lender or the Administrative Agent (as the case may be) and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted. Such indemnification shall be made within thirty (30) days from the date such Lender or the Administrative Agent (as the case may be) makes written demand therefor.

        (d)Evidence of Payment.    Within thirty (30) days after the date of any payment of Taxes or Other Taxes, the Borrowers shall furnish to the Administrative Agent, at its address referred to in Section 14.1, the original or a certified copy of a receipt evidencing payment thereof or other evidence of payment satisfactory to the Administrative Agent.

        (e)Delivery of Tax Forms.    Each Lender organized under the laws of a jurisdiction other than the United States or any state thereof shall deliver to the Borrowers, with a copy to the Administrative Agent, on the Closing Date or concurrently with the delivery of the relevant Assignment and Acceptance, as applicable, (i) two United States Internal Revenue Service Forms W-8ECI or Forms W-8BEN, as applicable (or successor forms) properly completed and certifying in each case that such Lender is entitled to a complete exemption from withholding or deduction for or on account of any United States federal income taxes, and (ii) an Internal Revenue Service Form W-8BEN or W-8ECI or successor applicable form, as the case may be, to establish an exemption from United States backup withholding taxes. Each such Lender further agrees to deliver to the Borrowers, with a copy to the Administrative Agent, a Form W-8BEN or W-8ECI, or successor applicable forms or manner of certification, as the case may be, on or before the date that any such form expires or becomes obsolete or after the occurrence of any event requiring a change in the most recent form previously delivered by it to the Borrowers, certifying in the case of a Form W-8BEN or W-8ECI that such Lender is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes (unless in any such case an event (including without limitation any change in treaty, law or regulation) has occurred prior to the date on which any such delivery would otherwise be required which renders such forms inapplicable or the exemption to which such forms relate unavailable and such Lender notifies the Borrowers and the Administrative Agent that it is not entitled to receive payments without deduction or withholding of United States federal income taxes) and, in the case of a Form W-8BEN or W-8ECI, establishing an exemption from United States backup withholding tax.

37

        (f)Survival.    Without prejudice to the survival of any other agreement of the Borrowers hereunder, the agreements and obligations of the Borrowers contained in this Section 5.11 shall survive the payment in full of the Obligations and the termination of the Commitments.

        SECTION 5.12Security.     The Obligations of the Borrowers shall be secured as provided in the Security Documents.

REPRESENTATIONS AND WARRANTIES OF THE BORROWERS

        SECTION 7.1Representations and Warranties.     To induce the Administrative Agent and Lenders to enter into this Agreement and to induce the Lenders to make Extensions of Credit, each Borrower hereby represents and warrants to the Administrative Agent and Lenders both before and after giving effect to the transactions contemplated hereunder that:

        (a)Organization; Power; Qualification.    Each Borrower and each Subsidiary thereof is duly organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation or formation, has the power and authority to own its properties and to carry on its business as now being and hereafter proposed to be conducted and is duly qualified and authorized to do business in each jurisdiction in which the character of its properties or the nature of its business requires such qualification and authorization, except where the failure to be duly qualified and authorized will not have a Material Adverse Effect. The jurisdictions in which each Borrower and each Subsidiary thereof are organized and qualified to do business as of the Closing Date are described on Schedule 7.1(a).

        (b)Ownership.    Each Subsidiary of each Borrower as of the Closing Date is listed on Schedule 7.1(b). As of the Closing Date, the capitalization of each Borrower and each Subsidiary thereof consists

38

of the number of shares, authorized, issued and outstanding, of such classes and series, with or without par value, described on Schedule 7.1(b). All outstanding shares have been duly authorized and validly issued and are fully paid and nonassessable. The shareholders of the Subsidiaries of each Borrower and the number of shares owned by each as of the Closing Date are described on Schedule 7.1(b). As of the Closing Date, there are no outstanding stock purchase warrants, subscriptions, options, securities, instruments or other rights of any type or nature whatsoever, which are convertible into, exchangeable for or otherwise provide for or permit the issuance of capital stock of any Borrower or any Subsidiary thereof, except as described on Schedule 7.1(b).

        (c)Authorization of Agreement, Loan Documents and Borrowing.    Each Borrower and each Subsidiary thereof has the right, power and authority and has taken all necessary corporate and other action to authorize the execution, delivery and performance of this Agreement and each of the other Loan Documents to which it is a party in accordance with their respective terms. This Agreement and each of the other Loan Documents have been duly executed and delivered by the duly authorized officers of each Borrower and each of its Subsidiaries party thereto, and each such document constitutes the legal, valid and binding obligation of each Borrower or its Subsidiary party thereto, enforceable in accordance with its terms, except as such enforcement may be limited by bankruptcy, insolvency, reorganization, moratorium or similar state or federal debtor relief laws from time to time in effect which affect the enforcement of creditors' rights in general and the availability of equitable remedies.

        (d)Compliance of Agreement, Loan Documents and Borrowing with Laws, Etc.    The execution, delivery and performance by each Borrower and each Subsidiary thereof of the Loan Documents to which each such Person is a party, in accordance with their respective terms, the Extensions of Credit hereunder, the granting of the Liens under the Security Documents and the transactions contemplated hereby do not and will not, by the passage of time, the giving of notice or otherwise, (i) require any Governmental Approval or violate any Applicable Law relating to any Borrower or any Subsidiary thereof, (ii) conflict with, result in a breach of or constitute a default under (A) the articles of incorporation, bylaws or other organizational documents of any Borrower or any Subsidiary thereof or (B) any indenture, agreement or other instrument to which such Person is a party or by which any of its properties may be bound or any Governmental Approval relating to such Person which could reasonably be expected to have a Material Adverse Effect, or (iii) result in or require the creation or imposition of any Lien upon or with respect to any property now owned or hereafter acquired by such Person other than Liens arising under the Loan Documents.

        (e)Compliance with Law; Governmental Approvals.    Each Borrower and each Subsidiary thereof (i) has all Governmental Approvals required by any Applicable Law for it to conduct its business, each of which is in full force and effect, is final and not subject to review on appeal and is not the subject of any pending or, to the best of its knowledge, threatened attack by direct or collateral proceeding, and (ii) is in compliance with each Governmental Approval applicable to it and in compliance with all other Applicable Laws relating to it or any of its respective properties, in each case except to the extent that any such lack of Governmental Approval or failure to comply would not have a Material Adverse Effect.

        (f)Tax Returns and Payments.    Each Borrower and each Subsidiary thereof has duly filed or caused to be filed all federal, state, material local and other tax returns required by Applicable Law to be filed, and has paid, or made adequate provision for the payment of, all federal, state, local and other taxes, assessments and governmental charges or levies upon it and its property, income, profits and assets which are due and payable. Except as set forth on Schedule 7.1(f) and except for claims for taxes which are being contested in good faith and as to which adequate reserves are maintained in accordance with GAAP, no Governmental Authority has asserted any Lien or other claim against any Borrower or Subsidiary thereof with respect to unpaid taxes which has not been discharged or resolved. The charges, accruals and reserves on the books of each Borrower and each Subsidiary thereof in

39

respect of federal, state, material local and other taxes for all Fiscal Years and portions thereof since the organization of such Borrower and each Subsidiary thereof are in the judgment of each such Borrower adequate, and each such Borrower does not anticipate any additional taxes or assessments for any of such years.

        (g)Intellectual Property Matters.    Each Borrower and each Subsidiary thereof owns or possesses rights to use all franchises, licenses, copyrights, copyright applications, patents, patent rights or licenses, patent applications, trademarks, trademark rights, trade names, trade name rights, copyrights and rights with respect to the foregoing which are required to conduct its business. No event has occurred which permits, or after notice or lapse of time or both would permit, the revocation or termination of any such rights, and no Borrower nor any Subsidiary thereof is liable to any Person for infringement under Applicable Law with respect to any such rights as a result of its business operations.

        (h)Environmental Matters.    In the ordinary course of its business, each Borrower conducts an ongoing review of the effect of Environmental Laws on the business, operations and properties of such Borrower and its Subsidiaries, in the course of which it identifies and evaluates associated liabilities and costs (including, without limitation, any capital or operating expenditures required for clean-up or closure of properties presently or previously owned, any capital or operating expenditures required to achieve or maintain compliance with environmental protection standards imposed by law or as a condition of any license, permit or contract, any related constraints on operating activities, including any periodic or permanent shutdown of any facility or reduction in the level of or change in the nature of operations conducted at any such facility, any costs or liabilities in connection with off-site disposal of wastes or Hazardous Substances, and any actual or potential liabilities to third parties, including employees, and any related costs and expenses). On the basis of this review, each Borrower has concluded that such associated liabilities and costs, including the costs of compliance with Environmental Laws, could not reasonably be expected to have a Material Adverse Effect.

        (i)ERISA.    

        (i)    As of the Closing Date, no Borrower nor any ERISA Affiliate maintains or contributes to, or has any obligation under, any Employee Benefit Plans other than those identified on Schedule 7.1(i);

        (ii)  Each Borrower and each ERISA Affiliate is in material compliance with all applicable provisions of ERISA and the regulations and published interpretations thereunder with respect to all Employee Benefit Plans except for any required amendments for which the remedial amendment period as defined in Section 401(b) of the Code has not yet expired. Other than as set forth on Schedule 7.1(i), each Employee Benefit Plan that is intended to be qualified under Section 401(a) of the Code has been determined by the Internal Revenue Service to be so qualified, and each trust related to such plan has been determined to be exempt under Section 501(a) of the Code. No liability has been incurred by any Borrower or any ERISA Affiliate which remains unsatisfied for any taxes or penalties with respect to any Employee Benefit Plan or any Multiemployer Plan;

        (iii)  Other than as set forth on Schedule 7.1(i), no Pension Plan has been terminated, nor has any accumulated funding deficiency (as defined in Section 412 of the Code) been incurred (without regard to any waiver granted under Section 412 of the Code), nor has any funding waiver from the Internal Revenue Service been received or requested with respect to any Pension Plan, nor has any Borrower or any ERISA Affiliate failed to make any contributions or to pay any amounts due and owing as required by Section 412 of the Code, Section 302 of ERISA or the terms of any Pension Plan prior to the due dates of such contributions under Section 412 of the Code or Section 302 of ERISA, nor has there been any event requiring any disclosure under Section 4041(c)(3)(C) or 4063(a) of ERISA with respect to any Pension Plan;

40

        (iv)  No Borrower nor any ERISA Affiliate has: (A) engaged in a nonexempt prohibited transaction described in Section 406 of the ERISA or Section 4975 of the Code, (B) incurred any liability to the PBGC which remains outstanding other than the payment of premiums and there are no premium payments which are due and unpaid, (C) failed to make a required contribution or payment to a Multiemployer Plan, or (D) failed to make a required installment or other required payment under Section 412 of the Code;

        (j)Margin Stock.    No Borrower nor any Subsidiary thereof is engaged principally or as one of its activities in the business of extending credit for the purpose of "purchasing" or "carrying" any "margin stock" (as each such term is defined or used in Regulation U of the Board of Governors of the Federal Reserve System). No part of the proceeds of any of the Loans or Letters of Credit will be used for purchasing or carrying margin stock or for any purpose which violates, or which would be inconsistent with, the provisions of Regulation T, U or X of such Board of Governors.

        (k)Government Regulation.    No Borrower nor any Subsidiary thereof is an "investment company" or a company "controlled" by an "investment company" (as each such term is defined or used in the Investment Company Act of 1940, as amended) and no Borrower nor any Subsidiary thereof is, or after giving effect to any Extension of Credit will be, subject to regulation under the Public Utility Holding Company Act of 1935 or the Interstate Commerce Act, each as amended, or any other Applicable Law which limits its ability to incur or consummate the transactions contemplated hereby.

        (l)Material Contracts.    Schedule 7.1(l) sets forth a complete and accurate list of all Material Contracts of the Borrowers and their Subsidiaries in effect as of the Closing Date not listed on any other Schedule hereto; other than as set forth in Schedule 7.1(l), each such Material Contract is, and after giving effect to the consummation of the transactions contemplated by the Loan Documents will be, in full force and effect in accordance with the terms thereof. The Borrowers and their Subsidiaries have delivered or made available to the Administrative Agent a true and complete copy of each Material Contract required to be listed on Schedule 7.1(l) or any other Schedule hereto.

        (m)Employee Relations.    Each Borrower and each Subsidiary thereof has a stable work force in place and is not, as of the Closing Date, party to any collective bargaining agreement nor has any labor union been recognized as the representative of its employees except as set forth on Schedule 7.1(m). No Borrower knows of any pending, threatened or contemplated strikes, work stoppage or other collective labor disputes involving its employees or those of its Subsidiaries, which would have a Material Adverse Effect.

        (n)Financial Statements.    The financial statements delivered on the Closing Date are complete and correct in all material respects and fairly present the assets, liabilities and financial position of the Borrowers and their Subsidiaries as at such dates, and the results of the operations and changes of financial position for the periods then ended. All such financial statements, including the related schedules and notes thereto, have been prepared in accordance with GAAP, except (i) for deviations from GAAP disclosed in the WMNS Purchase Agreement and (ii) in the case of the unaudited financial statements referred to above, for the omission of footnotes and ordinary year end adjustments). The Borrowers and their Subsidiaries have no Debt, obligation or other unusual forward

41

or long-term commitment which is not reflected in accordance with GAAP in the foregoing financial statements or in the notes thereto.

        (o)No Material Adverse Change.    Since December 31, 1999, there has been no material adverse change in the properties, business, operations, or condition (financial or otherwise) of the Borrowers and their Subsidiaries taken as a whole and no event has occurred or condition arisen that could reasonably be expected to have a Material Adverse Effect, except as previously disclosed in materials filed with the Securities and Exchange Commission after December 31, 1999 and prior to the Effective Date.

        (p)Solvency.    As of the Closing Date and after giving effect each Extension of Credit made hereunder, the Company and its Subsidiaries, taken as a whole, will be Solvent.

        (q)Titles to Properties.    Each Borrower and each Subsidiary thereof has such title to the real property owned by it as is necessary or desirable to the conduct of its business and valid and legal title to all of its personal property and assets, including, but not limited to, those reflected on the balance sheets of the Borrowers and their Subsidiaries delivered pursuant to Section 7.1(n), except those which have been disposed of by any Borrower or any Subsidiary thereof subsequent to such date which dispositions have been in the ordinary course of business or as otherwise expressly permitted hereunder.

        (r)Liens.    None of the properties and assets of any Borrower or any Subsidiary thereof is subject to any Lien, except Permitted Liens. No financing statement under the Uniform Commercial Code of any state which names any Borrower or any Subsidiary thereof or any of their respective trade names or divisions as debtor and which has not been terminated, has been filed in any state or other jurisdiction and no Borrower nor any Subsidiary thereof has signed any such financing statement or any security agreement authorizing any secured party thereunder to file any such financing statement, except to perfect Permitted Liens.

        (s)Debt and Guaranty Obligations.    Schedule 7.1(s) is a complete and correct listing of all Debt and Guaranty Obligations of each Borrower and each Subsidiary thereof as of the Closing Date in excess of $750,000. Each Borrower and each Subsidiary thereof have performed and are in compliance with all of the terms of such Debt and Guaranty Obligations and all instruments and agreements relating thereto, and no default or event of default, or event or condition which with notice or lapse of time or both would constitute such a default or event of default on the part of any Borrower or any Subsidiary thereof exists with respect to any such Debt or Guaranty Obligation.

        (t)Litigation.    Except for matters existing on the Closing Date and set forth on Schedule 7.1(t), there are no actions, suits or proceedings pending nor, to the knowledge of any Borrower, threatened against or in any other way relating adversely to or affecting any Borrower or any Subsidiary thereof or any of their respective properties in any court or before any arbitrator of any kind or before or by any Governmental Authority which, if adversely determined could reasonably be expected to have a Material Adverse Effect, and which are reasonably likely to be determined adversely to the Borrower or such Subsidiary.

        (u)Absence of Defaults.    No event has occurred or is continuing which constitutes a Default or an Event of Default.

        (v)Accounts.    Each Account shown on the most recent Borrowing Base Certificate is, as of the date of the Borrowing Base Certificate, qualified to be in the Borrowing Base.

        (w)  [Intentionally omitted.]

        (x)Accuracy and Completeness of Information.    All written information, reports and other papers and data other than financial projections produced by or on behalf of each Borrower and each Subsidiary thereof and furnished to the Lenders were, at the time the same were so furnished,

42

complete and correct in all material respects to the extent necessary to give the recipient a true and accurate knowledge of the subject matter. No document furnished or written statement other than financial projections made to the Administrative Agent or the Lenders by any Borrower or any Subsidiary thereof in connection with the negotiation, preparation or execution of this Agreement or any of the Loan Documents contains or will contain any untrue statement of a fact material to the creditworthiness of any Borrower or any Subsidiary thereof or omits or will omit to state a material fact necessary in order to make the statements contained therein not misleading. No Borrower is aware of any facts which it has not disclosed in writing to the Administrative Agent having a Material Adverse Effect, or insofar as any Borrower can now foresee, could reasonably be expected to have a Material Adverse Effect.

        SECTION 7.2Survival of Representations and Warranties, Etc.     All representations and warranties set forth in this Article VII and all representations and warranties contained in any certificate, or any of the Loan Documents (including but not limited to any such representation or warranty made in or in connection with any amendment thereto) shall constitute representations and warranties made under this Agreement. All representations and warranties made under this Agreement shall be made or deemed to be made at and as of the Closing Date, shall survive the Closing Date and shall not be waived by the execution and delivery of this Agreement, any investigation made by or on behalf of the Lenders or any borrowing hereunder.

ARTICLE VIII

        SECTION 13.1Appointment.     Each of the Lenders hereby irrevocably designates and appoints Wachovia as Administrative Agent and as Collateral Agent of such Lender, in each case, under this Agreement and the other Loan Documents for the term hereof and each such Lender irrevocably authorizes each of Wachovia as Administrative Agent and as Collateral Agent for such Lender, to take such action on its behalf under the provisions of this Agreement and the other Loan Documents and to exercise such powers and perform such duties as are expressly delegated to such Agent by the terms of this Agreement and such other Loan Documents, together with such other powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary elsewhere in this Agreement or such other Loan Documents, neither Agent shall have any duties or responsibilities, except those expressly set forth herein and therein, or any fiduciary relationship with any Lender, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or the other Loan Documents or otherwise exist against any Agent. Any reference to the Agent in this Article XIII shall be deemed to refer to the Administrative Agent or Collateral Agent, as applicable, solely in its capacity as Administrative Agent or Collateral Agent, as applicable, and not in its capacity as a Lender.

        SECTION 13.2Delegation of Duties.     The Agents may execute any of their respective duties under this Agreement and the other Loan Documents by or through agents or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties. No Agent shall be responsible for the negligence or misconduct of any agents or attorneys-in-fact selected by such Agent with reasonable care.

        SECTION 13.3Exculpatory Provisions.     Neither Agent nor any of such Agent's officers, directors, employees, agents, attorneys-in-fact, Subsidiaries or Affiliates shall be (a) liable for any action lawfully taken or omitted to be taken by it or such Person under or in connection with this Agreement or the other Loan Documents (except for actions occasioned solely by its or such Person's own gross negligence or willful misconduct), or (b) responsible in any manner to any of the Lenders for any recitals, statements, representations or warranties made by any Borrower or any Subsidiary thereof or any officer thereof contained in this Agreement or the other Loan Documents or in any certificate, report, statement or other document referred to or provided for in, or received by such Agent under or in connection with, this Agreement or the other Loan Documents or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or the other Loan Documents or for any failure of any Borrower or any Subsidiary thereof to perform its obligations hereunder or thereunder. No Agent shall be under any obligation to any Lender to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement, or to inspect the properties, books or records of the Borrowers or any of their Subsidiaries.

        SECTION 13.4Reliance by the Agents.     The Agents shall be entitled to rely, and shall be fully protected in relying, upon any note, writing, resolution, notice, consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype message, statement, order or other document or conversation believed by such Agent to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including, without limitation, counsel to the Borrowers), independent accountants and other experts selected by such Agent. The Agents may deem and treat the payee of any Note as the owner thereof for all purposes unless such Note shall have been transferred in accordance with Section 14.10 hereof. The Agents shall be fully justified in failing or refusing to take any action under this Agreement and the other Loan Documents unless such Agent shall first receive such advice or concurrence of the Required Lenders (or, when expressly required hereby or by the relevant other Loan Document, all the Lenders) as it deems appropriate or it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such

63

action except for its own gross negligence or willful misconduct. The Agents shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement and the Notes in accordance with a request of the Required Lenders (or, when expressly required hereby, all the Lenders), and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders and all future holders of the Notes.

        SECTION 13.5Notice of Default.     No Agent shall be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder unless it has received notice from a Lender or the Borrowers referring to this Agreement, describing such Default or Event of Default and stating that such notice is a "notice of default". In the event that any Agent receives such a notice, it shall promptly give notice thereof to the other Agent and to the Lenders. The Agents shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Required Lenders; provided that unless and until such Agent shall have received such directions, such Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of the Lenders, except to the extent that other provisions of this Agreement expressly require that any such action be taken or not be taken only with the consent and authorization or the request of the Lenders or Required Lenders, as applicable.

        SECTION 13.6Non-Reliance on the Agents and Other Lenders.     Each Lender expressly acknowledges that neither Agent nor any of such Agent's officers, directors, employees, agents, attorneys-in-fact, Subsidiaries or Affiliates has made any representations or warranties to it and that no act by any Agent hereinafter taken, including any review of the affairs of the Borrowers or any of their Subsidiaries, shall be deemed to constitute any representation or warranty by such Agent to any Lender. Each Lender represents to each Agent that it has, independently and without reliance upon any Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, financial and other condition and creditworthiness of the Borrowers and their Subsidiaries and made its own decision to make its Loans and issue or participate in Letter of Credit hereunder and enter into this Agreement. Each Lender also represents that it will, independently and without reliance upon any Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigation as it deems necessary to inform itself as to the business, operations, property, financial and other condition and creditworthiness of the Borrowers and their Subsidiaries. Except for notices, reports and other documents expressly required to be furnished to the Lenders by an Agent hereunder or by the other Loan Documents, no Agent shall have any duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, property, financial and other condition or creditworthiness of the Borrowers or any of their Subsidiaries which may come into the possession of any Agent or any of its respective officers, directors, employees, agents, attorneys-in-fact, Subsidiaries or Affiliates.

        SECTION 13.7Indemnification.     The Lenders agree to indemnify each Issuing Lender and each of the Administrative Agent, Collateral Agent, Documentation Agent and Syndication Agent in its respective capacity as such and (to the extent not reimbursed by the Borrowers and without limiting the obligation of the Borrowers to do so), ratably according to the respective amounts of their Revolving Credit Commitment Percentage, Term A Loan Percentage and/or Term B Loan Percentage, as applicable, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever which may at any time (including, without limitation, at any time following the payment of the Notes or any Reimbursement Obligation) be imposed on, incurred by or asserted against any Agent in any way relating to or arising out of this Agreement or the other Loan Documents, or any documents contemplated by or referred to

64

herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by any Agent under or in connection with any of the foregoing; provided that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting solely from such Agent's bad faith, gross negligence or willful misconduct. The agreements in this Section 13.7 shall survive the payment of the Notes, any Reimbursement Obligation and all other amounts payable hereunder and the termination of this Agreement.

        SECTION 13.8The Agents in Their Individual Capacity.     Each Agent and its respective Subsidiaries and Affiliates may make loans to, accept deposits from and generally engage in any kind of business with the Borrowers as though such Agent were not an Agent hereunder. With respect to any Loans made or renewed by it and any Note issued to it and with respect to any Letter of Credit issued by it or participated in by it, such Agent shall have the same rights and powers under this Agreement and the other Loan Documents as any Lender and may exercise the same as though it were not an Agent, and the terms "Lender" and "Lenders" shall include the Agent in its individual capacity, if applicable.

        SECTION 13.9Resignation of the Agents; Successor Agents.     Subject to the appointment and acceptance of a successor as provided below, any Agent may resign at any time by giving notice thereof to the Lenders and the Borrowers. Upon any such resignation, the Required Lenders shall have the right to appoint a successor Agent, which successor shall have minimum capital and surplus of at least $500,000,000. If no successor Agent shall have been so appointed by the Required Lenders and shall have accepted such appointment within thirty (30) days after such Agent's giving of notice of resignation, then such Agent may, on behalf of the Lenders, appoint a successor Agent, which successor shall have minimum capital and surplus of at least $500,000,000. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations hereunder. After any retiring Agent's resignation hereunder as Agent, the provisions of this Section 13.9 shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as Agent.

        SECTION 13.10Documentation Agent and Syndication Agent.     The Documentation Agent and the Syndication Agent, each in its respective capacity as Documentation Agent or Syndication Agent, shall have no duties or responsibilities under this Agreement or any other Loan Document.

        (c)  To the extent any Borrower is required, by reason of its Obligations hereunder, to pay to the Administrative Agent and the Lenders an amount greater than the amount of Loans actually made available to or for the account of such Borrower, such Borrower shall have an enforceable right of contribution against the remaining Borrowers, and the remaining Borrowers shall be jointly and severally liable, for repayment of the full amount of such excess payment. Subject only to the subordination provided in the following subsection (f), such Borrower further shall be subrogated to any and all rights of the Administrative Agent and the Lenders against the remaining Borrowers to the extent of such excess payment.

73

        (d)  To the extent that any Borrower would, but for the operation of this Section 14.19 and by reason of its Obligations hereunder or its obligations to other Subsidiaries under this Section 14.19, be rendered insolvent for any purpose under Applicable Law, each of the Borrowers hereby agrees to indemnify such Borrower in an amount at least equal to the amount necessary to prevent such Borrower from having been rendered insolvent by reason of the incurring of any such obligations.

        (e)  To the extent that any Borrower would, but for the operation of this Section 14.19, be rendered insolvent under any Applicable Law by reason of its incurring of obligations to any other Borrower under the foregoing subsections (c) and (d) above, such Borrower shall, in turn, have rights of contribution and indemnity, to the full extent provided in the foregoing subsections (c) and (d) above, against the remaining Borrowers, such that all Obligations of all of the Borrowers hereunder and under this Section 14.19 shall be allocated in a manner such that no Borrower shall be rendered insolvent for any purpose under Applicable Law by reason of its incurring of such obligations.

        (f)    The rights of any Borrower to contribution, subrogation and indemnity under this Section 14.19 or under Applicable Law shall in all events and all respects be subject and subordinate to the rights of the Administrative Agent and the Lenders under this Agreement and subject to the prior full, final and indefeasible payment to the Administrative Agent and the Lenders of all Obligations and no such right may be exercised until all of such Obligations have been fully, finally and indefeasibly paid and such payments are in no event subject to avoidance under Title 11 of the United States Code or any other Applicable Law.

        SECTION 14.20Inconsistencies with Other Documents; Independent Effect of Covenants.     

        (a)  In the event there is a conflict or inconsistency between this Agreement and any other Loan Document, the terms of this Agreement shall control; provided, that any provision of the Security Documents which imposes additional burdens on any Borrower or any Subsidiary thereof or further restricts the rights of any Borrower or any Subsidiary thereof or gives the Agents or Lenders additional rights shall not be deemed to be in conflict or inconsistent with this Agreement and shall be given full force and effect.

        (b)  The Borrowers expressly acknowledge and agree that each covenant contained in Articles IX, X, or XI hereof shall be given independent effect. Accordingly, the Borrowers shall not engage in any transaction or other act otherwise permitted under any covenant contained in Articles IX, X, or XI if, before or after giving effect to such transaction or act, the Borrowers shall or would be in breach of any other covenant contained in Articles IX, X, or XI.
