PART I

Item 1. Business

We are a leading supplier of integrated software and services to the process industries, which consist of oil and gas, petroleum, chemicals, pharmaceuticals and other industries that manufacture and produce products from a chemical process. Our software and services are designed to improve a variety of business activities, including plant and process design, economic evaluation, production, production planning and scheduling, and managing operational performance. These solutions help our customers improve their competitiveness and profitability by increasing revenues, reducing operating costs, reducing working capital requirements and decreasing capital expenditures.

We offer two principal product lines: engineering & innovation, and plant operations/supply chain. Each of these product lines accounted for approximately one-half of our total revenues in our fiscal year ended June 30, 2004.

•: Our engineering & innovation solutions are desktop applications and services that help companies design and improve their plants and processes. Our customers use our engineering software and services to improve the way they develop and deploy manufacturing assets to improve return on capital. They can use our engineering products to design and manage intellectual property in order to reduce cost of investment, improve physical plant operating performance and bring new products to market more quickly. Our flagship engineering products include Aspen Plus, HYSYS and Aspen Zyqad.
•: Our plant operations/supply chain solutions allow process manufacturers to operate their plants and supply chains more efficiently, from customer demand through manufacturing to the delivery of the finished product. Our manufacturing/supply chain software and services are designed to enable companies to run their supply chains and plants more efficiently, helping them make better- informed, more profitable decisions. These solutions help companies make decisions that can reduce fixed and variable costs in the plant, improve product yields, procure the right raw materials and evaluate opportunities for cost savings and efficiencies in their enterprise-wide supply chain. Our flagship manufacturing supply chain products include DMC Plus, Aspen MIMI, Aspen PIMS and Aspen IP.21.

To address challenges facing companies in the process industries, we are developing solutions specifically targeted at the emerging Enterprise Operations Management, or EOM, market. The EOM market bridges the gap between enterprise IT business systems and plant floor systems. Our EOM solutions broaden the scope of optimization across the entire enterprise by linking engineering, plant and business systems to improve visibility of a company's enterprise-wide operations. Much like the enterprise resource planning, or ERP, market evolved from providing individual, best-in-class applications to providing a streamlined integrated solution suite, the EOM market is evolving out of the industry's need to have a more integrated solution to manage day-to-day operations. The foundation of our EOM solutions is derived from our engineering and plant operations/supply chain solutions and are designed to help companies obtain real-time operational data and to forecast or simulate the economic impact of potential decisions. The Aspen Operations Manager Suite is a key element of our EOM solution and provides functionality such as role-based visualization, performance scorecarding, event management and integration infrastructure. Companies can use our EOM solutions to help quickly determine the most profitable action and gain operational efficiencies.

Our customer base of over 1,500 process manufacturers includes 46 of the world's 50 largest chemical companies, 23 of the world's 25 largest petroleum refiners, 19 of the world's 20 largest pharmaceutical companies and 17 of the world's 20 largest engineering and construction firms that serve the process industries. We have established a network of strategic relationships to leverage our internal sales and marketing efforts, enhance the breadth of our solutions and expand our

implementation capabilities. This network includes relationships with systems integrators such as Accenture and technology providers such as Intergraph, Microsoft, Schlumberger and UOP.

Industry Background

The process industries consist of oil and gas, petroleum, chemicals, pharmaceutical and other industries that provide products from a chemical process. Process manufacturers face a number of significant challenges, including volatile raw materials prices, overcapacity, environmental and regulatory requirements, and managing complex global businesses.

To succeed in an increasingly competitive global environment, process manufacturers must simultaneously reduce costs and increase efficiency, responsiveness and customer satisfaction. Because process manufacturing tends to be asset-intensive, increases in profitability in these industries depend substantially upon reducing the costs of raw materials, energy and capital. Given the large production volumes typical in the process industries and the relatively low profit margins characteristic of many sectors within the process industries, even relatively small reductions in raw material or energy requirements or small improvements in input costs, throughput or product yields can significantly increase the profitability of the process manufacturing enterprise.

We believe that the process industries pose significant challenges because of the complex activities and supply chains required to purchase raw materials, manufacture products, and deliver final products to customers. Factors that make it difficult for these companies to optimize these processes and make optimal economic decisions include the following:

•: products are manufactured in continuous processes that are unpredictable and difficult to model;
•: production sequence and raw material specification both have a major impact on feasibility and profitability;
•: multiple, interdependent products are made simultaneously, making production planning complicated;
•: manufacturing plants are sophisticated and extremely capital intensive; and
•: transportation logistics are complex.

Historically, technology solutions have played a major role in helping process companies to drive productivity improvements. In the 1980s, this increase in efficiency came from the use of distributed control systems, or DCS, to automate the management of plant hardware. Process manufacturers initially automated their production processes by deploying DCS, which used computer hardware systems, communication networks and industrial instruments to measure, record and automatically control process variables.

In the 1990s, productivity was enhanced by the adoption of ERP systems to streamline administrative functions. Process manufacturers have automated key business processes by implementing ERP systems, which are software solutions that optimize the flow of business information across the enterprise. Although DCS and ERP solutions can be important components of a solution to improve manufacturing enterprise performance, they do not incorporate either the detailed chemical engineering knowledge essential to optimize the design and operation of related manufacturing processes or the plant performance data required to support more intelligent real-time decision making.

Following multiple mergers and acquisitions among process manufacturing companies, the global operations of process manufacturers became more complicated and difficult to manage, since they were managing more plant assets than ever before. As these companies expand, they require enterprise information technology, or IT, solutions that provide clear visibility to support mission-critical business decisions and that enable operational improvement across the entire organization.

With the widespread adoption of ERP systems, many companies are capturing a significant amount of information about their operational performance. However, ERP is acting as a "cash register" for their businesses and telling them what has happened in the past. Although these systems are improving information flow and streamlining transactions, their influence on day-to-day operational activities is limited. Our EOM solutions provide decision support tools that use real-time plant information to determine the best economic alternative for the enterprise. These decisions cannot be adequately made by simply analyzing historical data from our ERP or from disparate software applications that are not integrated together. By modeling future operational behavior, using consistent data and models of their facilities, we are able to show our customers the path to capturing economic value and materially improve profitability.

To optimize performance, process manufacturers are demanding tools that enable them to improve their highly complex production methods and processes. To meet these objectives, intelligent decision-support products must provide an accurate understanding of a plant's capabilities, as well as accurate planning and collaborative forecasting information.

As process manufacturers have become more adept at using products that optimize individual engineering and plant operations/supply chain business processes, they increasingly are seeking additional performance improvements by integrating these products, both with one another and with DCS, ERP and other enterprise systems, to provide real-time, intelligent decision support. To achieve these objectives, companies are implementing plant operations/supply chain solutions to integrate related business processes across a single production facility. Companies are also implementing integrated manufacturing/supply chain solutions to extend the solutions across multiple plants within an enterprise, by adding planning and scheduling functionality and extending integration beyond the enterprise walls.

Process manufacturers look to optimize their supply chains by reducing cycle times substantially, adjusting production quickly to meet changing customer requirements, synchronize key business processes with plants and customers across numerous geographies and time zones, and quote delivery dates more accurately and reliably. Traditional solutions and emerging software integration vendors lack the deep process knowledge essential to solve the complex problems faced by process manufacturers attempting to achieve true optimization of their enterprises, from design to production to management of the extended supply chain.

The AspenTech Advantage

Process manufacturers use our solutions to improve their competitiveness, not only by reducing raw material and energy use, cycle time, inventory cost and time to market, but increasingly by synchronizing and streamlining key business processes. Our competitive advantage is based on the following key attributes:

Substantial process industry expertise. By developing software for the process industries for more than 20 years, we believe we have amassed the world's largest collection of process industry domain knowledge to develop and implement our products. Our founders and executives have pioneered many of the most significant advances that today are considered industry-standard software applications across a wide variety of engineering, manufacturing and supply chain applications. Our services and development staff are well qualified to deliver value to our customers based on the practical experience gained from supporting IT installations for more than 1,500 process manufacturers worldwide.

This significant base of chemical engineering expertise, process manufacturing experience and industry know-how serves as the foundation for the proprietary solution methods, physical property models and data estimation techniques embedded in our software solution. We continually enhance our software applications through extensive interaction with our customers, some of which have worked with our products over the past twenty years. To complement our software expertise, we have

assembled a staff of approximately 400 project engineers to provide implementation, advanced process control, real-time optimization, supply chain management and other consulting services. We believe this consulting team is the largest of any competitive independent solution provider. Our expertise spans a number of the process industry's vertical markets, from oil and gas, chemicals, petrochemicals and refining to pharmaceuticals, specialty chemicals and polymers, and others.

Large and valuable customer base. We view our customer base of more than 1,500 process manufacturers as an important strategic asset and as evidence of one of the strongest franchises in the industry. We count among our customers 46 of the world's 50 largest chemical companies, 23 of the world's 25 largest petroleum refiners, and 19 of the world's 20 largest pharmaceutical companies. We also have numerous leading customers in other vertical markets. In addition, 17 of the 20 largest engineering and construction firms that serve these industries use our design software. These relationships enable us to identify and develop or acquire solutions that best meet the needs of our customers, and they are a valuable part of our efforts to penetrate the process industries with new software solutions. We believe that our customer base is underpenetrated in the use of strategic enterprise-wide products, particularly for our plant operations/supply chain products. As process manufacturers increasingly focus on integration and optimization of their extended supply chains, we expect many of our existing customers to be among the first to implement our newly-developed enterprise solutions.

Rapid, high return on investment. We believe that customers purchase our products because our products provide rapid, demonstrable and significant returns on investment. Because of the large production volumes and relatively low profit margins typical in many of the process industries, even small improvements in productivity can generate substantial recurring benefits. First-year savings can exceed the software and implementation costs of our products. Our integrated solution, whether applied across a plant, an enterprise or an extended supply chain, can yield even greater returns. In addition, our products generate important organizational efficiencies and operational improvements, the dollar benefits of which can be difficult to quantify.

Complete, integrated solution. While some vendors offer stand-alone products that compete with one or more of our products, we believe we are the only provider that offers a comprehensive solution to process manufacturers that addresses key business processes across the enterprise and trading partners. Our solutions can be used on a stand-alone basis, integrated with one another or integrated with third-party applications. Customers can initially choose to implement a point solution or our integrated solution, which is scalable as the customer's needs evolve. A key part of this integration and scalability is enabled by our Operations Manager Suite, which is an important differentiator from our competitors. Our plant operations/supply chain offering integrates multiple business processes within a single plant, across the enterprise and with customers, suppliers and other trading partners. The breadth of our solutions expand the overall value we can bring to our customers and represent an important source of competitive differentiation.

Strategy

Our strategy is to leverage our position as a technology leader with both our engineering and plant operations/supply chain solutions and to deliver new, innovative solutions that will create economic value for our customers. To implement this strategy we intend to:

Profitably grow existing products into an integrated suite of scalable vertical industry solutions. We intend to increase the growth and profitability of our existing engineering and plant operations/supply chain product lines. Through the continued development of an integrated suite of scalable vertical industry modules built around key industry business processes, we believe that we will be able to provide a broader set of capabilities and deliver a higher value proposition to existing and prospective

customers. We recently launched our Aspen Oil & Gas vertical market solution, which combines several of our key technologies to provide an integrated solution to the upstream oil and gas industry.

Establish AspenTech as the Enterprise Operations Management solution provider of choice. As a result of the broad array of products we offer in our engineering & innovation and plant operations/supply chain product lines, we believe we are in a unique position to offer fully integrated solutions that use consistent data and models to provide enhanced visibility and decision-making based on accurate, real-time information. These systems can offer existing and new customers a virtual "operational cockpit" to monitor their key performance indicators, running their businesses using a true picture of their operations rather than estimates based on historical data. With these integrated solutions, we are enabling companies to embrace new strategies, creating demand-driven supply chains, lowering cost of IT ownership and being more responsive to market changes. The Aspen Operations Manager Suite, launched in 2003, is a key element of our EOM solution.

Invest selectively in new, high-value solutions. We intend to invest selectively in a few new solutions that unlock new sources of value for customers in all segments of the process industries. To deliver value in the EOM market, we are introducing a few targeted applications that incorporate technology from both our engineering and manufacturing/supply chain product lines. These applications include:

•: Aspen Oil & Gas Asset Optimization: a solution for the oil and gas industry that provides a single asset model framework enabling a consolidated analysis from the refinery back to product development;
•: Aspen Petroleum Planning & Scheduling: an integrated solution that improves planning and scheduling production at refineries;
•: Aspen Chemicals Performance Management: a solution that provides plant information visibility and performance management for a broad arrange of chemical manufacturers; and
•: Aspen RefSYS: a solution that enables refinery-wide modeling via a single asset model framework with an initial focus on off-line operations analysis and optimization, with extensions planned for on-line optimization with capabilities to maintain consistency with planning, scheduling and closed-loop blending.

Provide an open architecture, easy-to-integrate solution that lowers IT lifecycle cost of ownership. A key component of our EOM strategy is to develop and deploy an open architecture application platform that allows for easier integration between our applications and between third-party applications, provides consistent data and models across the enterprise and enhances workflow. Customer benefits of our application platform include lower integration and maintenance costs, enhanced interoperability between a wide variety of applications, including ours, tightened linkage between operational decisions and financial impact by the use of consistent models and improved business process execution by enhanced workflow. We have a current commercial release of the application platform in the marketplace.

Continue to forge strong relationships with strategic alliance partners. Alliance partners are an important part of our strategy to help us accelerate our time to bring products to market and provide us with additional resources to implement enterprise solutions. We have invested considerable time and resources into our alliance with Accenture to create new enterprise-enabled products for the process industry market. We believe that the success of these products will be an important driver of our future growth prospects. We also have technology alliances with Intergraph, Microsoft, Schlumberger and UOP. We intend to continue to work with a select number of strategic alliance partners that will help us deliver our vision of enterprise value to our key process industry customers.

Products: Software and Services

We provide software and services that enable our customers to make improvements across their enterprises. Our engineering software products are used on the engineer's desktop and typically require a minimal amount of services. These solutions are typically sold on a term basis and represented approximately 68% of our fiscal 2004 software license revenues. Our plant operations/supply chain products are used throughout the plant and across the supply chain and typically are services-intensive due to their complex nature. These solutions represented approximately 50% of our fiscal 2004 total revenue.

Our major global process industry customers are increasingly looking to partner with a few strategic software providers that can help them operate efficiently and profitably. To ensure that we continue as one of these core software providers, we are focusing our development efforts on completing the transformation of our stand-alone, point technologies into products that can be configured into scalable, enterprise-enabled solutions.

We design our products to capture process knowledge in a consistent, accurate and reliable form based on models that customers can use as the basis for decision making. These models and the associated knowledge captured in the supporting IT systems provide real-time, intelligent decision support across the entire process manufacturing enterprise. Our software products can be linked with a customer's existing ERP products and DCS to further improve a customer's ability to gather, analyze and use this information across the process manufacturing life cycle.

Engineering. In the process industries, maximizing profit begins with optimal design. Process manufacturers must be able to address a variety of challenging questions relating to strategic planning, collaborative engineering and de-bottlenecking and process improvement—from where they should locate their facilities, to how they can make their products at the lowest cost, to what is the best way to operate for maximum efficiency. To address these issues, they must improve asset optimization to enable faster, better execution of complex projects. Our engineering solutions help companies maximize their return on plant assets and enable collaboration with engineers on common models and projects. These products form the foundation for optimizing process manufacturers' supply chains and manufacturing facilities. By using our products to create and capture knowledge in the form of models, information can be re-used across the business. Profit improvements result from:

•: reduced capital and operating costs;
•: reduced time to ramp-up manufacturing;
•: lowered manufacturing cost base and increased asset utilization;
•: increased production flexibility and agility; and
•: efficient execution of capital projects.

Our flagship engineering products include Aspen Plus, HYSYS and Aspen Zyqad. Our engineering tools are based on an open environment and are implemented on Microsoft's operating systems. Implementation of our engineering products does not typically require substantial consulting services, although services may be provided for customized model designs and process synthesis.

Plant Operations/supply chain. Our plant operations/supply chain products focus on optimizing companies' day-to-day process industry activities, enabling them to make smarter, more profitable decisions—from choosing the right raw materials, to improving plant performance, to delivering finished product in the most cost-effective manner. We have several product families in the plant operations/supply chain product line that are specifically tailored to the business processes of each of our vertical markets.

The ever-changing nature of the process industries means new profit opportunities can appear at any time. To identify and seize these opportunities, process manufacturers must be able to increase their access to data and information across the value chain, optimize planning and collaborate across the value chain, and detect and exploit supply chain opportunities. Our plant operations/supply chain products help companies develop their optimal operating plans based on real-time demand and market trends. Some of the benefits from these products include improved responses to customer requirements, decreased planning costs, reduced inventory-carrying costs and decreased response times.

The process industries' typical production cycle offers many opportunities for optimizing profits. Process manufacturers must be able to address a wide range of issues driving execution efficiency and cost, from selecting the right feedstock and raw materials, to production scheduling, to identifying the right balance among customer satisfaction, costs and inventory. Our manufacturing/supply chain products support the execution of the optimal operating plan in real-time and include the key functions of sourcing, making and delivering physical products to customers.

In the process industries, the selection of the right raw material has a significant impact on product quality and profitability. Because many products in the process industries can be made from a variety of raw materials using different techniques, there typically is far greater complexity in process manufacturing than in discrete manufacturing. In this environment, process manufacturers must be able to make quick decisions as to which feedstock is the most profitable. Our manufacturing/supply chain product line helps to capture economic value for customers by increasing margins from optimal feedstock selection, reducing raw material and logistics costs and reducing inventory-carrying costs.

In order to take advantage of the emerging EOM market, we have developed a suite of modular vertical EOM solutions to address the major challenges of various process industries. We have also developed a new suite called Aspen Operations Manager Suite, to enable real-time performance management through seamless integration between our solutions, existing enterprise IT systems and third-party applications. The Aspen Operations Manager Suite provides functionality such as role-based visualization, performance scorecarding, event management and an integration infrastructure. Key customers for the Aspen Operations Manager suite include Dupont, Conoco Phillips and Shell Oil.

Services

We offer implementation, advanced process control, real-time optimization and other consulting services in order to provide our customers with complete solutions. These services are primarily associated with the implementation of our plant operations/supply chain solutions. Customers have historically used our engineering solutions without implementation assistance. However, we are beginning to offer more engineering-related services to customers, so services relating to engineering may represent a higher percentage of our consulting revenue in the future. Customers that purchase plant operations/supply chain products frequently require implementation assistance from us and our partners.

Customers who obtain consulting services from us typically engage us to provide such services over periods of up to 24 months. We generally charge customers for consulting services, ranging from supply chain to on-site advanced process control and optimization services, on a fixed-price basis or time-and-materials basis.

As of September 1, 2004, we employed a staff of approximately 400 project engineers to provide consulting services to our customers. We believe this large team of experienced and knowledgeable project engineers provides an important source of competitive differentiation. We primarily hire as project engineers individuals who have obtained doctoral or master's degrees in chemical engineering or a related discipline or who have significant relevant industry experience. Our employees include experts in fields such as thermophysical properties, distillation, adsorption processes, polymer processes,

industrial reactor modeling, the identification of empirical models for process control or analysis, large-scale optimization, supply distribution systems modeling and scheduling methods.

Historically, most licensees of our planning and scheduling products and a limited number of licensees of our process information management and supply chain management systems have obtained implementation consulting services from third-party vendors. Our strategy is to continue to develop and expand relationships with third-party consultants in order to provide a secondary channel of consulting services.

Partnerships

Our strategy is to establish partnerships with a few select companies that offer a complementary set of technologies, services and industry expertise that help us deliver integrated EOM solutions to process manufacturers. Historically, most of our license sales have been generated through our direct sales force. A key strategic initiative is to increase the amount of our software license sales that are derived from partners. Companies such as Accenture, Intergraph, Microsoft, Schulumberger and UOP can help us deliver compelling, differentiated solutions to the marketplace and can help us accelerate our growth within our target markets.

Technology and Product Development

Our base of chemical engineering expertise, process manufacturing experience and industry know-how serves as the foundation for the proprietary solution methods, physical property models and industry-specific business process knowledge embedded in our software solutions. Our software and services solutions combine three of our core competencies:

•: We support sophisticated empirical models generated from advanced mathematical algorithms developed by our employees. In addition, we support rigorous models of chemical manufacturing processes and the equipment used in those processes. We have used these advanced algorithms to develop proprietary models that provide highly accurate representations of the chemical and physical properties of a broad range of materials typically encountered in the chemicals, petroleum and other process industries.
•: We develop software that models key customer manufacturing and business processes and automates the workflow of these processes. This software integrates our broad product line so that the data used in manufacturing processes are seamlessly passed between the applications used in each step of the business processes.
•: We have invested significantly in supply chain software, which embeds sophisticated technology allowing customers to optimize their extended supply chain activities. In addition, this software embeds key knowledge about the details of how manufacturing and supply chain operations function in the process industries.

Our product development activities are currently focused on strengthening the integration of our key products, expanding the set of business processes our software covers, exploiting web technology, and enhancing and simplifying the user interfaces. During fiscal 2002, 2003 and 2004, we incurred research and development costs of $74.5 million, $65.1 million and $59.1 million, respectively, which represented 23.2%, 20.2% and 18.1% of total revenue, respectively. As of September 1, 2004, we employed a product development staff of approximately 390 people.

Customers

Our software solutions are installed at the facilities of more than 1,500 customers worldwide. The following table sets forth a partial selection of our customers from which we generated at least $300,000 of revenues in fiscal 2003 or 2004. For fiscal 2004, the percentage our license revenue derived from specific vertical markets were as follows: 35% from refining and oil and gas, 30% from chemicals, 20% from engineering and construction design firms, and 15% from other segments of the process industries, the largest of which were pharmaceutical and consumer package goods.

Sales and Marketing

We employ a value-based sales approach, offering our customers a comprehensive suite of software and service products that enhance the efficiency and productivity of their process manufacturing operations. We have increasingly focused on selling our products as a strategic investment by our customers and therefore target our principal sales efforts at senior management levels, including chief executive officers and senior decision makers in manufacturing, operations and technology. We believe our development of new enterprise-enabled products and our alliance with Accenture will help us to continue to focus and deliver our message to the chief executive, chief financial and chief information officers of our customers.

Because the complexity and cost of our products often result in extended sales cycles, we believe that the development of long-term, consultative relationships with our customers is essential to a successful selling strategy. To develop these relationships, we have organized our worldwide sales around our two solution sets, engineering and manufacturing/supply chain, as well as focusing on a select number of worldwide strategic accounts.

In order to market the specific functionality and other complex technical features of our software products, each sales account manager and global account manager works with specialized teams of technical sales engineers and product specialists organized for each sales and marketing effort. Our technical sales engineers typically have advanced degrees in chemical engineering or related disciplines and actively consult with a customer's plant engineers. Product specialists share their detailed knowledge of the specific features of our software solutions as they apply to the unique business processes of different vertical industries.

We currently have three direct sales offices in cities in the United States and 21 direct sales offices in cities outside of the United States, including Barcelona, Beijing, Brussels, Calgary, Cambridge (England), Dusseldorf, Singapore and Tokyo. In geographic areas of lower customer concentration, we use sales agents and other resellers to leverage our direct sales force and to provide local coverage and first-line support. Our overall sales force, which consists of quota carrying sales account managers, sales services personnel, business support engineers, partner organization personnel, industry business unit professionals, marketing personnel and support staff, consisted of approximately 320 persons on September 1, 2004.

We supplement our direct sales efforts with a variety of marketing initiatives, including public relations activities, campaigns to promote awareness among industry analysts, user groups and our bi-annual conference, AspenWorld. AspenWorld has become a prominent forum for industry participants, including process manufacturing executives and analysts, to discuss emerging technologies and process industry technologies and to attend seminars led by industry experts. We will hold our next AspenWorld conference from October 11 through 15, 2004.

We also license our software products at a substantial discount to universities that agree to use our products in teaching and research. We believe that students' familiarity with our products will stimulate future demand once the students enter the workplace. Currently, more than 650 universities use our software products in undergraduate instruction.

Competition

Our markets are highly competitive and are characterized by rapid technological change. We expect the intensity of competition in our markets to increase in the future as existing competitors enhance and expand their product and service offerings and as new participants enter the market. Increased competition may result in price reductions, reduced profitability and loss of market share. We cannot assure you that we will be able to compete successfully against existing or future competitors. Some of our customers and companies with which we have strategic relationships also are, or in the future may be, competitors of ours.

Many of our competitors have greater financial, marketing and other resources than we have in a particular market segment or overall. Competitors with greater financial resources may be able to offer lower prices, additional products or services, or other incentives that we cannot match or offer. These competitors may be in a stronger position to respond quickly to new technologies and may be able to undertake more extensive marketing campaigns. They also may adopt more aggressive pricing policies and make more attractive offers to potential customers, employees and strategic partners.

Many of our competitors have established, and in the future may establish, cooperative relationships with third parties to improve their product offerings and to increase the availability of

their products to the marketplace. In addition, competitors may make strategic acquisitions to increase their ability to gain market share or improve the quality or marketability of their products. These cooperative relationships and strategic acquisitions could reduce our market share, require us to lower our prices, or both.

Our primary competitors differ between our two principal product areas:

•: Our engineering software competes with products of businesses such as Simulation Sciences (a division of Invensys), Chemstations, Shell Global Solutions, Honeywell, ABB, MDC Technology, Aveva Group (formerly Cadcentre), WinSim (formerly ChemShare) and Process Systems Enterprise. As we expand our engineering solutions into the collaborative process lifecycle management market and the EOM market, we may face competition from companies that we have not typically competed against in the past, such as Agile, Parametric Technology, SAP, Honeywell, ABB, Invensys, Siemens and EDS.
•: Our manufacturing/supply chain software competes with products of companies such as Honeywell, Invensys, ABB, Siemens, Rockwell, i2 Technologies, Manugistics and components of SAP's supply chain offering.

In addition, we face competition in all areas of our business from large companies in the process industries that have internally developed their own proprietary software solutions.

We believe the key competitive differentiator in our industry is the value, or return on investment, that our software and services provide. We seek to develop and offer an integrated suite of targeted, high-value vertical industry solutions that can be implemented with relatively limited service requirements. We believe this approach provides us with a competitive advantage over many of our competitors, which offer software products that are more service-based. The principal competitive factors in our industry also include:

•: breadth and depth of technology;
•: domain expertise of sales and service personnel;
•: extent of consistent global support;
•: performance and reliability;
•: price; and
•: time to market.

In addition, we are currently in the process of trying to settle a complaint filed against us by the Federal Trade Commission, or FTC. The FTC matter is discussed below under "Factors that may affect our operating results and stock price—Risks Related to Our Business." The settlement has not received, and may not receive, final approval from the FTC and the impact on our competitive environment from this potential settlement is unlikely to be known until several months after the settlement has officially been approved.

Intellectual Property

We regard our software as proprietary and rely on a combination of copyright, patent, trademark and trade secret laws, license and confidentiality agreements, and software security measures to protect our proprietary rights. We have obtained or applied for patent protection in the United States with respect to some of our intellectual property, but generally do not rely on patents as a principal means of protecting intellectual property. We have registered or applied to register some of our significant trademarks in the United States and in selected other countries.

We generally enter into non-disclosure agreements with our employees and customers, and historically have restricted access to our software products' source codes, which we regard as proprietary information. In a few cases, we have provided copies of the source codes for products to customers solely for the purpose of special product customization and have deposited copies of the source codes for products in third-party escrow accounts as security for ongoing service and license obligations. In these cases, we rely on non-disclosure and other contractual provisions to protect our proprietary rights.

The laws of many countries in which our products are licensed may not protect our products and intellectual property rights to the same extent as the laws of the United States. The laws of many countries in which we license our products protect trademarks solely on the basis of registration. We currently possess a limited number of trademark registrations in selected foreign jurisdictions and have applied for foreign copyright and patent registrations, which correspond to the United States trademarks, copyrights and patents described above, to protect our products in foreign jurisdictions where we conduct business.

The steps we have taken to protect our proprietary rights may not be adequate to deter misappropriation of our technology or independent development by others of technologies that are substantially equivalent or superior to our technology. Any misappropriation of our technology or development of competitive technologies could harm our business. We could incur substantial costs in protecting and enforcing our intellectual property rights.

Moreover, from time to time third parties may assert patent, trademark, copyright and other intellectual property rights to technologies that are important to our business. In such an event, we may be required to incur significant costs in litigating a resolution to the asserted claims. The outcome of any litigation might require that we pay damages or obtain a license of a third party's proprietary rights in order to continue licensing our products as currently offered. If such a license were required, it might not be available on terms acceptable to us, or at all.

We believe that the success of our business depends more on the quality of our proprietary software products, technology, processes and know-how than on trademarks, copyrights or patents. While we consider our intellectual property rights to be valuable, we do not believe that our competitive position in the industry is dependent simply on obtaining legal protection for our software products and technology. Instead, we believe that the success of our business depends primarily on our ability to maintain a leadership position in developing our proprietary software products, technology, information, processes and know-how. Nevertheless, we attempt to protect our intellectual property rights with respect to our products and development processes through trademark, copyright and patent registrations, both foreign and domestic, whenever appropriate as part of our ongoing research and development activities.

Employees

As of September 1, 2004, we had a total of 1,550 full-time employees. None of our employees is represented by a labor union, except that approximately 21 employees of Hyprotech UK Ltd belong to Prospect Union. We have experienced no work stoppages and believe that our employee relations are good.

Factors that may affect our operating results and stock price

Investing in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described below before purchasing our common stock. The risks and uncertainties described below are not the only ones facing our company. Additional risks and uncertainties may also impair our business operations. If any of the following risks actually occur, our business, financial condition or results of operations would likely suffer. In that case, the trading price of our common stock could fall, and you may lose all or part of the money you paid to buy our common stock.

Risks Related to Our Business

The FTC has filed a complaint against us with respect to our acquisition of Hyprotech, and an adverse outcome would have a material adverse effect on our business, operating results and financial position.

On August 7, 2003, the staff of the FTC filed a civil administrative complaint alleging that our acquisition of Hyprotech in May 2002 was anticompetitive in violation of Section 5 of the Federal Trade Commission Act and Section 7 of the Clayton Act. On July 15, 2004 the FTC announced that it had accepted a proposed consent decree for public comment. The public comment period ended August 13, 2004, and the FTC is currently considering whether to make the proposed consent decree final. For a further description of the background and proceedings for this matter, please see "Item 3. Legal Proceedings—FTC Complaint" below.

If the proposed consent decree is not approved by the FTC and is returned to litigation, and our acquisition of Hyprotech is determined to have violated the law, we would be subject to one of a variety of possible remedies, any of which would materially limit our ability to operate under our current business plan and would have a material adverse affect on our operating results and financial position.

We understand that the FTC has typically prevailed in merger challenges, and that, if this matter returns to litigation, there is a substantial probability that the FTC would prevail in its challenge to our acquisition of Hyprotech. Because of the length of the appeals process, the outcome of this matter may not be determined for several years. The likely outcome of this matter is not estimable at this time.

If the FTC were to prevail in this challenge, it could seek to impose one of a variety of remedies, any of which would have a material adverse effect on our ability to continue to operate under our current business plan and on our results of operations and financial position. These potential remedies include reversal of the Hyprotech acquisition such that we would no longer own Hyprotech or any of its assets, or mandatory licensing of Hyprotech software products and our other engineering software products to one or more companies, which could include one of our competitors. Potential remedies could also include creation of a new competitor through the divestiture of certain of our engineering software products, assets, technology, employees, and customer agreements. The price we would receive from a buyer or licensee is likely to be less than the price we originally paid.

In addition, Hyprotech products have become material to our business, including for example HYSYS.Process and HYSYS.Dynamics, and Hyprotech technologies have been incorporated into products that are material to our business strategy, including for example RefSYS. Moreover, former Hyprotech personnel now hold a variety of positions throughout our company, and we may experience a disruption of our operations if we were to lose the services of some of these personnel as a result of the enforcement of a remedy.

If the proposed consent decree is approved in present form or in amended form, there is no assurance that we will be able to complete a transaction within the time periods of the consent decree, and if a transaction is completed by us or by a trustee appointed by the FTC, there could be negative, adverse effects on our operations.

The FTC may approve the consent decree in its current form or it may request amendments to the consent decree. We are not required to accept amendments, but the FTC's approval of a consent decree may be dependent on amending it. If the consent decree is approved in its current form, we will have 60 or 90 days to complete a transaction. If we do not close a transaction within the applicable period then the FTC may appoint a trustee to find a buyer for approval by the FTC. If an FTC-approved acquirer closes a transaction with us under the terms of the consent decree, then there will be adverse effects on our operations, including, the loss of our current operator training business, the creation of a new competitor that acquires the divested assets, increased costs in supporting the products for the FTC-approved acquirer under a two year support agreement, and other terms and conditions that may be negotiated with an FTC-approved acquirer.

The FTC investigation and the related proceeding have had, and will continue to have, adverse effects on our operations.

The FTC investigation and the related proceeding have had, and will continue to have, the following adverse effects:

•: The attention of our senior management personnel has been, and will continue to be, diverted from our business operations.
•: Uncertainties resulting from the FTC action and proceedings may harm our ability to compete in the marketplace, including our ability to negotiate license renewals with our customers.
•: The cost of defending the proceeding has been, and, if the consent decree is not approved, is likely to continue to be substantial and could significantly reduce our cash flow and adversely impact our operating results.

As of the filing date of this report, we have accrued $17.9 million to cover the cost of (1) professional service fees associated with our cooperation in the FTC's investigation since its commencement on June 7, 2002, and (2) estimated future professional services fees relating to the initial proceeding and our preparation in advance of such proceeding. If these estimates are insufficient to cover all future costs relating to the proceeding, we may need to accrue additional amounts, which may have a material adverse effect on our results of operations.

Our lengthy sales cycle makes it difficult to predict quarterly revenue levels and operating results.

Because license and implementation fees for our software products are substantial and the decision to purchase our products typically involves members of our customers' senior management, the sales process for our solutions is lengthy and can exceed one year. Accordingly, the timing of our license revenues is difficult to predict, and the delay of an order could cause our quarterly revenues to fall substantially below our expectations and those of public market analysts and investors. Moreover, to the extent that we succeed in shifting customer purchases away from individual software products and toward more costly integrated suites of software and services, our sales cycle may lengthen, which could increase the likelihood of delays and cause the effect of a delay to become more pronounced. Delays in sales could cause significant shortfalls in our revenues and operating results for any particular period.

Fluctuations in our quarterly revenues, operating results and cash flow may cause the market price of our common stock to fall.

Our revenues, operating results and cash flow have fluctuated in the past and may fluctuate significantly in the future as a result of a variety of factors, many of which are outside of our control, including:

•: demand for our products and services;
•: our customers' purchasing patterns;

•: the length of our sales cycle;
•: changes in the mix of our license revenues and service revenues;
•: the timing of introductions of new solutions and enhancements by us and our competitors;
•: seasonal weakness in the first quarter of each fiscal year (which for us is the quarter ended September 30), primarily caused by a slowdown in business in some of our international markets;
•: the timing of our investments in new product development;
•: the mix of domestic and international sales;
•: changes in our operating expenses; and
•: fluctuating economic conditions, particularly as they affect companies in the oil and gas, chemicals, petrochemicals and petroleum industries.

We ship software products within a short period after receipt of an order and typically do not have a material backlog of unfilled orders for software products. Consequently, revenues from software licenses in any quarter are substantially dependent on orders booked and shipped in that quarter. Historically, a majority of each quarter's revenues from software licenses has come from license agreements that have been entered into in the final weeks of the quarter. Therefore, even a short delay in the consummation of an agreement may cause our revenues to fall below expectations of public market analysts and investors for that quarter.

Since our expense levels are based in part on anticipated revenues, we may be unable to adjust our spending quickly enough to compensate for any revenue shortfall and any revenue shortfall would likely have a disproportionately adverse effect on our operating results. We expect that the factors listed above will continue to affect our operating results for the foreseeable future. Because of the factors listed above, we believe that period-to-period comparisons of our operating results are not necessarily meaningful and should not be relied upon as indications of future performance.

If, due to one or more of the foregoing factors or an unanticipated cause, our operating results fail to meet the expectations of public market analysts and investors in a future quarter, the market price of our common stock would likely decline.

We derive a majority of our total revenues from customers in the oil and gas, chemicals, petrochemicals and petroleum industries, which are highly cyclical, and our operating results may suffer if these industries experience an economic downturn.

We derive a majority of our total revenues from companies in the oil and gas, chemicals, petrochemicals and petroleum industries. Accordingly, our future success depends upon the continued demand for manufacturing optimization software and services by companies in these process manufacturing industries. The oil and gas, chemicals, petrochemicals and petroleum industries are highly cyclical and highly reactive to the price of oil, as well as general economic conditions. In the past, worldwide economic downturns and pricing pressures experienced by oil and gas, chemical, petrochemical and petroleum companies have led to consolidations and reorganizations. These downturns, pricing pressures and restructurings have caused delays and reductions in capital and operating expenditures by many of these companies. These delays and reductions have reduced demand for products and services like ours. A recurrence of these industry patterns, as well as general domestic and foreign economic conditions and other factors that reduce spending by companies in these industries, could harm our operating results in the future.

If economic conditions and the markets for our products do not improve, sales of our product lines, particularly our manufacturing and supply chain product suites, will be adversely affected.

Adverse changes in the economy and continuing global uncertainty have caused delays and reductions in information technology spending by our customers and a consequent deterioration of the markets for our products and services, particularly our manufacturing/supply chain product suites. If these adverse economic conditions continue or worsen, we will experience further reductions, delays, and postponements of customer purchases that will negatively impact our revenue and operating results. If economic and political conditions and the market for our products do not improve and our revenues decline, our business could be harmed, and we may not be able to further reduce our costs to align them with these decreased revenues.

If we do not compete successfully, we may lose market share.

Our markets are highly competitive. Our engineering software competes with products of businesses such as Simulation Sciences (a division of Invensys), Chemstations, Shell Global Solutions, Honeywell, ABB, MDC Technology, Aveva Group (formerly Cadcentre), WinSim (formerly ChemShare) and Process Systems Enterprise. Our manufacturing/supply chain software competes with products of companies such as Honeywell, Invensys, ABB, Rockwell, i2 Technologies, Manugistics and components of SAP's supply chain offering. As we expand our engineering solutions into the collaborative process lifecycle management market and the EOM market, we may face competition from companies that we have not typically competed against in the past or competition from companies in areas where we have not competed in the past, such as Agile, Parametric Technology, SAP, Honeywell, ABB, Invensys, Siemens and EDS. We also face competition in all areas of our business from large companies in the process industries that have internally developed their own proprietary software solutions.

Many of our competitors have greater financial, marketing and other resources than we have. In addition, many of our competitors have established, and may in the future continue to establish, cooperative relationships with third parties to improve their product offerings and to increase the availability of their products to the marketplace. In addition, competitors may make strategic acquisitions to increase their ability to gain market share or improve the quality or marketability of their products. These cooperative relationships and strategic acquisitions could reduce our market share, require us to lower our prices, or both. Increased competition may result in price reductions, reduced profitability and loss of market share. We cannot assure you that we will be able to compete successfully against existing or future competitors.

In addition, the FTC has accepted for public comment, but not yet made final, a proposed consent decree that would require us to divest our operator training business, the AXSYS business, and rights to the Hyprotech product line, maintain certain technical standards with respect to the Hyprotech product line for 5 years, and provide the FTC-approved acquirer of rights to the Hyprotech product line with all releases for the Hyprotech products for 2 years. If the consent decree is approved we could face competition from the FTC-approved acquirer.

If we do not continue to make the technological advances required by the marketplace, our business could be seriously harmed.

Enterprises are requiring their application software vendors to provide greater levels of functionality and broader product offerings. Moreover, competitors continue to make rapid technological advances in computer hardware and software technology and frequently introduce new products, services and enhancements. We must continue to enhance our current product line and develop and introduce new products and services that keep pace with increasingly sophisticated customer requirements and the technological developments of our competitors. Our business and

operating results could suffer if we cannot successfully respond to the technological advances of others or if our new products or product enhancements and services do not achieve market acceptance.

Under our business plan, we are investing significantly in the development of new business process products that are intended to anticipate and meet the emerging needs of our target market. We are focusing significantly on development of these new products, which means we will not invest as substantially in the continued enhancement of our current products. We cannot assure you that our new product development will result in products that will meet market needs and achieve significant market acceptance.

If we are unable to successfully market our products to senior executives of potential customers, our revenue growth may be limited.

With the development of our integrated manufacturing/supply chain solutions and our EOM solutions, we frequently must focus on selling the strategic value of our technology to the highest executive levels of customer organizations, typically the chief executive officer, chief financial officer or chief information officer. If we are not successful at selling and marketing to senior executives, our revenue growth and operating results could be materially and adversely affected.

If we are unable to develop or maintain relationships with strategic partners, our revenue growth may be harmed.

An element of our growth strategy is to strategically partner with a few select third-party implementation partners that market and integrate our products. If our current partners terminate their existing relationships with us, or if we do not adequately train a sufficient number of systems integrator partners, or if potential partners focus their efforts on integrating or co-selling competing products to the process industries, our future revenue growth could be limited and our operating results could be materially and adversely affected. If our partners fail to implement our solutions for our customers properly, the reputations of our products and services and our company could be harmed and we might be subject to claims by our customers. We intend to continue to establish business relationships with technology companies to accelerate the development and marketing of our products and services. To the extent that we are unsuccessful in maintaining our existing relationships and developing new relationships, our revenue growth may be materially and adversely affected.

We may suffer losses on fixed-price engagements.

We derive a substantial portion of our total revenues from service engagements and a significant percentage of these engagements have been undertaken on a fixed-price basis. Under these fixed-price engagements, we bear the risk of cost overruns and inflation, and as a result, any of these engagements may be unprofitable. In the past, we have had cost overruns on fixed-price service engagements. In addition, to the extent that we are successful in shifting customer purchases to our integrated suites of software and services and we price those engagements on a fixed-price basis, the size of our fixed-price engagements may increase, which could cause the impact of an unprofitable fixed-price engagement to have a more pronounced impact on our operating results.

Our business may suffer if we fail to address the challenges associated with international operations.

We derived approximately one-half of our total revenues from customers outside the United States in each of the fiscal years ended June 30, 2002, 2003 and 2004. We anticipate that revenues from customers outside the United States will continue to account for a significant portion of our total revenues for the foreseeable future. Our operations outside the United States are subject to additional risks, including:

•: unexpected changes in regulatory requirements, exchange rates, tariffs and other barriers;

•: political and economic instability;
•: less effective protection of intellectual property;
•: difficulties in managing distributors and representatives;
•: difficulties in staffing and managing foreign subsidiary operations;
•: difficulties and delays in translating products and product documentation into foreign languages;
•: difficulties and delays in negotiating software licenses compliant with accounting revenue recognition requirements in the United States;
•: difficulties in collecting trade accounts receivable in other countries; and
•: potentially adverse tax consequences.

The impact of future exchange rate fluctuations on our operating results cannot be accurately predicted. In recent years, we have increased the extent to which we denominate arrangements with international customers in the currencies of the countries in which the software or services are provided. From time to time we have engaged in, and may continue to engage in, hedges of a significant portion of installment contracts denominated in foreign currencies. Any hedging policies implemented by us may not be successful, and the cost of these hedging techniques may have a significant negative impact on our operating results.

We may not be able to protect our intellectual property rights, which could make us less competitive and cause us to lose market share.

We regard our software as proprietary and rely on a combination of copyright, patent, trademark and trade secret laws, license and confidentiality agreements, and software security measures to protect our proprietary rights. We have registered or have applied to register several of our significant trademarks in the United States and in certain other countries. We generally enter into non-disclosure agreements with our employees and customers, and historically have restricted access to our software products' source codes, which we regard as proprietary information. In a few cases, we have provided copies of the source code for some of our products to customers solely for the purpose of special product customization and have deposited copies of the source code for some of our products in third-party escrow accounts as security for ongoing service and license obligations. In these cases, we rely on non-disclosure and other contractual provisions to protect our proprietary rights.

The steps we have taken to protect our proprietary rights may not be adequate to deter misappropriation of our technology or independent development by others of technologies that are substantially equivalent or superior to our technology. Any misappropriation of our technology or development of competitive technologies could harm our business, and could force us to incur substantial costs in protecting and enforcing our intellectual property rights. The laws of some countries in which our products are licensed do not protect our products and intellectual property rights to the same extent as the laws of the United States.

Third-party claims that we infringe upon the intellectual property rights of others may be costly to defend or settle and could damage our business.

We cannot be certain that our software and services do not infringe issued patents, copyrights, trademarks or other intellectual property rights of third parties. Litigation regarding intellectual property rights is common in the software industry, and we may be subject to legal proceedings and claims from time to time, including claims of alleged infringement of intellectual property rights of third parties by us or our licensees concerning their use of our software products and integration technologies and services. Although we believe that our intellectual property rights are sufficient to

allow us to market our software without incurring liability to third parties, third parties may bring claims of infringement against us. Because our software is integrated with our customers' networks and business processes, as well as other software applications, third parties may bring claims of infringement against us, as well as our customers and other software suppliers, if the cause of the alleged infringement cannot easily be determined. Such claims may be with or without merit. Claims of alleged infringement may have a material adverse effect on our business and may discourage potential customers from doing business with us on acceptable terms, if at all. Defending against claims of infringement may be time-consuming and may result in substantial costs and diversion of resources, including our management's attention to our business. Furthermore, a party making an infringement claim could secure a judgment that requires us to pay substantial damages. A judgment could also include an injunction or other court order that could prevent us from selling our software or require that we re-engineer some or all of our products. Claims of intellectual property infringement also might require us to enter costly royalty or license agreements. We may be unable, however, to obtain royalty or license agreements on terms acceptable to us or at all. Our business, operating results and financial condition could be harmed significantly if any of these events occurred, and the price of our common stock could be adversely affected. Furthermore, former employers of our current and future employees may assert that our employees have improperly disclosed confidential or proprietary information to us. In addition, we have agreed, and may agree in the future, to indemnify certain of our customers against claims that our software infringes upon the intellectual property rights of others. We could incur substantial costs in defending ourselves and our customers against infringement claims. In the event of a claim of infringement, we, as well as our customers, may be required to obtain one or more licenses from third parties, which may not be available on acceptable terms, if at all. Defense of any lawsuit or failure to obtain any such required licenses could harm our business, operating results and financial condition and the price of our common stock. In addition, although we carry general liability insurance, our current insurance coverage may not apply to, and likely would not protect us from, all liability that may be imposed under these types of claims.

Because some of our software products incorporate technology licensed from, or provided by, third parties, the loss of our right to use that technology or defects in that third party technology could harm our business.

Some of our software products contain technology that is licensed from, or provided by, third parties. Any significant interruption in the supply or support of any such third-party software could adversely affect our sales, unless and until we can replace the functionality provided by the third-party software. Because some of our software incorporates software developed and maintained by third parties, we depend on these third parties to deliver and support reliable products, enhance our current software, develop new software on a timely and cost-effective basis and respond to emerging industry standards and other technological changes. In other instances we provide third-party software with our current software, and we depend on these third parties to deliver reliable products, provide underlying product support and respond to emerging industry standards and other technological changes. The failure of these third parties to meet these criteria could harm our business.

Our software is complex and may contain undetected errors.

Like many other complex software products, our software has on occasion contained undetected errors or "bugs." Because new releases of our software products are initially installed only by a selected group of customers, any errors or "bugs" in those new releases may not be detected for a number of months after the delivery of the software. These errors could result in loss of customers, harm to our reputation, adverse publicity, loss of revenues, delay in market acceptance, diversion of development resources, increased insurance costs or claims against us by customers.

We may be subject to significant expenses and damages because of liability claims.

The sale and implementation of certain of our software products and services, particularly in the areas of advanced process control and optimization, may entail the risk of product liability claims. Our software products and services are often integrated with our customers' networks and software applications and are used in the design, operation and management of manufacturing processes at large facilities, often for mission critical applications. Any errors, defects, performance problems or other failure of our software could result in significant claims against us for damages or for violations of environmental, safety and other laws and regulations. In addition, the failure of our software to perform to customer expectations could give rise to warranty claims. Our agreements with our customers generally contain provisions designed to limit our exposure to potential product liability claims. It is possible, however, that the limitation of liability provisions in our agreements may not be effective as a result of federal, state or local laws or ordinances or unfavorable judicial decisions. A substantial product liability claim against us could materially and adversely harm our operating results and financial condition. Even if our software is not at fault, a product liability claim brought against us could be time consuming, costly to defend and harmful to our operations. In addition, although we carry general liability insurance, our current insurance coverage may be insufficient to protect us from all liability that may be imposed under these types of claims.

Implementation of our products can be difficult and time-consuming, and customers may be unable to implement our products successfully or otherwise achieve the benefits attributable to our products.

Our products are intended to work with complex business processes. Some of our software, such as customized scheduling applications and integrated supply chain products, must integrate with the existing computer systems and software programs of our customers. This can be complex, time-consuming and expensive. As a result, some customers may have difficulty in implementing or be unable to implement these products successfully or otherwise achieve the benefits attributable to these products. Customers may also make claims against us relating to the functionality, performance or implementation of this software. Delayed or ineffective implementation of the software products or related services may limit our ability to expand our revenues and may result in customer dissatisfaction, harm to our reputation and may result in customer unwillingness to pay the fees associated with these products.

If we are not successful in attracting and retaining management team members and other highly qualified individuals in our industry, we may not be able to successfully implement our business strategy.

Our ability to establish and maintain a position of technology leadership in the highly competitive software market depends in large part upon our ability to attract and retain highly qualified managerial, sales and technical personnel. Several of our executive officers have not entered into an employment agreements with us. In the future, we may experience the departure of senior executives due to competition for talent from start-ups and other companies. Our future success depends on a continued, successful management transition and will also depend on our continuing to attract, retain and motivate highly skilled employees. Competition for employees in our industry is intense. We may be unable to retain our key employees or attract, assimilate or retain other highly qualified employees in the future. We have from time to time in the past experienced, and we expect to continue to experience in the future, difficulty in hiring and retaining highly skilled employees with appropriate qualifications.

Our common stock may experience substantial price and volume fluctuations.

The equity markets have from time to time experienced extreme price and volume fluctuations, particularly in the high technology sector, and those fluctuations have often been unrelated to the operating performance of particular companies. In addition, factors such as our financial performance, announcements of technological innovations or new products by us or our competitors, as well as

market conditions in the computer software or hardware industries, may have a significant impact on the market price of our common stock.

In the past, following periods of volatility in the market price of a public company's securities, securities class action litigation has often been instituted against companies. This type of litigation could result in substantial costs and a diversion of management's attention and resources.

Our common stockholders may experience further dilution as a result of provisions contained in our outstanding Series D convertible preferred stock and warrants.

The terms of our outstanding securities may result in substantial dilution to existing common stockholders. In August 2003, we issued 300,300 shares of Series D-1 convertible preferred stock, or Series D-1 preferred, and delivered cash and 63,064 shares of Series D-2 convertible preferred stock, or Series D-2 preferred, in consideration for the surrender of all of our outstanding Series B-I and B-II convertible preferred stock, or Series B preferred. Each share of our Series D-1 preferred and Series D-2 preferred, which we refer to collectively as Series D preferred, is currently convertible, at the holder's option, into 100 shares of our common stock and may be converted into additional shares of our common stock upon certain events as a result of antidilution provisions in our charter. In addition, we issued warrants to purchase up to 7,267,286 shares of common stock, which we refer to as the WD warrants, and exchanged existing warrants to purchase 791,044 shares of common stock for warrants to purchase 791,044 shares of common stock, which we refer to as the WB warrants. The WD warrants and WB warrants are currently exercisable for an aggregate of 8,058,330 shares of our common stock and may be converted into additional shares upon certain events as a result of antidilution provisions in the warrants. The Series D preferred, together with the WD warrants and WB warrants, were issued to several investment partnerships managed by Advent International Corporation and to holders of our Series B preferred. We refer to these transactions as the Series D financing.

In addition to the Series D preferred and the WD and WB warrants, we currently have additional warrants outstanding that are exercisable to purchase 1,023,474 shares of common stock at an exercise price of $9.76 per share and 9,720 shares of common stock at an exercise price of $120.98. Our common stockholders would be subject to substantial dilution if the Series D preferred is converted into common stock or if our outstanding warrants are exercised for common stock.

Each share of Series D preferred is entitled to a cumulative dividend of 8.0% of the stated value per share of such Series D preferred per year, payable at the discretion of the board of directors or upon conversion of the Series D preferred to common stock or redemption of the Series D preferred. Accumulated dividends, when and if declared by our board, could be paid in cash or, subject to specified conditions, common stock. If we elect to pay dividends in shares of common stock, we will issue a number of shares of common stock equal to the quotient obtained by dividing the dividend payment by the volume weighted average of the sale prices of the common stock on the Nasdaq National Market for 20 consecutive trading days, ending on the fourth trading day prior to the required dividend payment date.

We are obligated to register for public sale shares of common stock issuable pursuant to our outstanding Series D preferred and warrants, and sales of those shares may result in a decrease in the price of our common stock.

We have granted rights to require that we register under the Securities Act the shares of common stock issuable upon the conversion of, or as dividends on, the Series D preferred and upon the exercise of either the WB warrants or WD warrants:

•: Series D-1 preferred. The holders of the Series D-1 preferred have the right to demand that we file on their behalf up to four registration statements covering shares of common stock issuable

upon (a) conversion of the Series D-1 preferred and (b) exercise of the WD warrants issued to the holders of the Series D-1 preferred.

•: Series D-2 preferred. We previously filed a registration statement that covers all of the shares of common stock issuable upon (a) conversion of the Series D-2 preferred and (b) exercise of the WB and WD warrants issued to the initial holders of the Series D-2 preferred.

In addition, to the extent we elect to pay dividends on the Series D preferred in shares of our common stock, we are required to register such shares. Any sale of common stock into the public market by the holders of the Series D preferred pursuant to a registration statement could cause a decline in the trading price of our common stock.

Our repayment obligations under our convertible debentures or the repurchase of our convertible debentures in the open market could have a material adverse effect on our financial condition.

In June 1998, we completed a convertible debt offering of $86,250,000 in aggregate principal amount of our 5¹/4% convertible subordinated debentures due June 15, 2005, which we refer to as the convertible debentures. We set aside $45,000,000 of the Series D financing proceeds to redeem or repurchase, at or prior to maturity, a portion of the convertible debentures. Even assuming we apply all of the set-aside proceeds to redeem the convertible debentures, we will still be required to dedicate a substantial portion of our cash flows from operations, including from the sale of receivables, to repay the principal of and interest on the remaining convertible debentures. As of September 1, 2004, we had repurchased convertible debentures in the aggregate principal amount of $29,505,000. We may choose to repurchase additional convertible debentures in the open market, subject to compliance with applicable laws and approval of our board of directors. We cannot guarantee, however, that we will be able to effect these repurchases at favorable prices. Our further repurchases of convertible debentures will reduce the cash we have available to fund operations, research and product development, capital expenditures and other general corporate purposes. We have incurred net losses in the past and may incur losses in the future that may impair our ability to generate the cash required to meet our obligations under the convertible debentures. If we cannot generate sufficient cash to meet these obligations, we may be required to incur additional indebtedness or raise additional capital.

We may need to raise additional capital in the future and may not be able to secure adequate funds on terms acceptable to us or at all.

We expect that our current cash balances, cash-equivalents, short-term investments, proceeds from sales of installment contracts, funds available under our bank line of credit, and cash flows from operations will be sufficient to meet our working capital and capital expenditure requirements for at least the next twelve months. We may need to obtain additional financing thereafter or earlier, however, if our current plans and projections prove to be inaccurate or our expected cash flows prove to be insufficient to fund our operations because of lower-than-expected revenues, unanticipated expenses, including those related to the FTC proceedings or their outcome, or other unforeseen difficulties.

Our sales of receivables are an important part of our cash management program. Historically, we have had arrangements to sell long-term contracts to two financial institutions, General Electric Capital Corporation and Fleet Business Credit Corporation, and in December 2003 we entered into a third such arrangement with Silicon Valley Bank. These contracts represent amounts due over the life of existing term licenses. During fiscal 2004, our installments receivable balance decreased to $89.2 million at June 30, 2004 from $108.1 million at June 30, 2003. Under the three arrangements, we sold installments receivable of $97.4 million during the fiscal year ended June 30, 2004. Our ability to continue these arrangements or replace them with similar arrangements is important to maintain adequate funding.

Our ability to obtain additional financing will depend on a number of factors, including market conditions, our operating performance and investor interest. These factors may make the timing, amount, terms and conditions of any financing unattractive. In addition, the uncertain outcome of the FTC complaint impairs our ability to obtain additional financing. Until this complaint is resolved, or if any resolution is materially adverse to us, we expect our ability to obtain additional financing will be substantially impaired. If adequate funds are not available or are not available on acceptable terms, we may have to forego strategic acquisitions or investments, reduce or defer our development activities, or delay our introduction of new products and services. Any of these actions may seriously harm our business and operating results.

The holders of our Series D preferred and WB and WD warrants own a substantial portion of our capital stock that may afford them significant influence over our affairs.

As of June 30, 2004, the Series D preferred (as converted to common stock) represented 42.3% of our outstanding common stock and the WB and WD warrants were exercisable for a number of shares representing 9.4% of our outstanding common stock (ignoring certain limitations on the ability to convert such shares or exercise such warrants). As a result, the holders of the Series D preferred and the WB and WD warrants, if acting together, would have the ability to delay or prevent a change in control of our company that may be favored by other stockholders and otherwise exercise significant influence over all corporate actions requiring stockholder approval, irrespective of how our other stockholders may vote, including:

•: any amendment of our certificate of incorporation or bylaws;
•: the approval of some mergers and other significant corporate transactions, including a sale of substantially all of our assets; or
•: the defeat of any non-negotiated takeover attempt that might otherwise benefit the public stockholders.

In addition, the holders of the Series D-1 preferred have elected four of our board members. Accordingly, the holders of our Series D-1 preferred may be able to exert substantial influence over matters submitted for board approval.

Our corporate documents and provisions of Delaware law may prevent a change in control or management that stockholders may consider desirable.

Section 203 of the Delaware General Corporation Law and our charter and by-laws contain provisions that might enable our management to resist a takeover of our company. These provisions could have the effect of delaying, deferring, or preventing a change in control of our company or a change in our management that stockholders may consider favorable or beneficial. These provisions could also discourage proxy contests and make it more difficult for you and other stockholders to elect directors and take other corporate actions. These provisions could also limit the price that investors might be willing to pay in the future for shares of our common stock.

Item 2. Properties

Our principal offices occupy approximately 110,000 square feet of office space in Cambridge, Massachusetts. The lease of this office space expires on September 30, 2012. We have agreements to sub-lease 10,000 square feet of this space that expire through April 2008, and are actively seeking to sub-lease an additional 20,000 square feet of this space. We also lease space for our Houston, Texas facilities. This lease encompasses approximately 150,000 square feet and expires March 1, 2012. In June 2004 we executed a buy-out of this lease, and in August 2004 we entered into a new lease in Houston that encompasses approximately 90,000 square feet and expires in July 2016. In addition to these two facilities we and our subsidiaries also own or lease office space in Carlsbad, California; Rockville, Maryland; New Providence, New Jersey; Midlothian, Virginia; Bothell, Washington; LaHulpe, Belgium; Calgary, Alberta, Canada; Cambridge, England; Warrington, England; Didcot, England; Tokyo, Japan; Best, The Netherlands; Singapore; Beijing, China; Barcelona, Spain; and other locations where additional sales and customer support offices are located. We believe that our existing and planned facilities are adequate for our needs for the foreseeable future and that, if additional space is needed, such space will be available on acceptable terms.

Item 3. Legal Proceedings

FTC Complaint

In May 2002, we acquired Hyprotech Ltd. and related subsidiaries of AEA Technology plc, an English private limited company, for a purchase price of £67.5 million. In June 2002, we received a letter from the FTC notifying us that it had commenced an investigation of the competitive effects of the Hyprotech acquisition. Because the acquisition was not reportable under the Hart-Scott-Rodino Act, the FTC had not conducted any pre-merger review of the Hyprotech acquisition. In September 2002, after we had supplied certain background information, the FTC issued a document subpoena and a Civil Investigative Demand, or CID. We responded to the subpoena, the CID, second requests for information and interviews that were subsequently issued over the period from October 2002 through March 2003. On August 7, 2003, the FTC announced that it had authorized its staff to file a civil administrative complaint alleging that our acquisition of Hyprotech was anti-competitive in violation of Section 5 of the Federal Trade Commission Act and Section 7 of the Clayton Act. The FTC staff filed its complaint the same day.

On July 15, 2004, the FTC announced that it had accepted a proposed consent decree for public comment. The public comment period ended August 13, 2004, and the FTC is currently considering whether to make the proposed consent decree final. The FTC may approve the proposed consent decree in its current form, require amendments to the proposed consent decree as a condition to approval, or reject the proposed consent decree and return the case to litigation or drop the case altogether. There is no time period within which the FTC must make its decision. A copy of the complaint, as well as information regarding the complaint and general information about the FTC's administrative procedures and possible remedies resulting from FTC merger challenges, can be found on the FTC's website at www.ftc.gov.

If the FTC approves the proposed consent decree in its current form, then we would be allowed to complete a sale to an FTC-approved buyer within 90 days of the order becoming final if we have entered into a definitive agreement with a potential buyer and submitted an application for approval of that buyer to the FTC within 5 days of the order being approved. If we have not identified a potential buyer, than we will have 60 days from the date on which the order becomes final to complete the sale required by the order. If we fail to close a transaction within the 60 or 90 day timeframes, then the FTC may appoint a trustee who will be empowered to find an acquirer of the assets offered under the consent decree. The trustee will have an initial one year period to complete the sale. This period may be extended at the FTC's discretion for up to two additional years.

Under the terms of the published proposed consent decree we would sell our operator training services business and rights to the Hyprotech product line to an FTC-approved buyer, maintain certain technical standards with respect to the Hyprotech product line for 5 years, and provide the FTC-approved buyer of rights to the Hyprotech product line with all releases for the Hyprotech products for 2 years. The proposed consent decree provides for us to obtain rights to the Hyprotech products from the FTC-approved buyer. The Hyprotech product AXSYS was sold to Bentley Systems, Inc. in accordance with the terms of the proposed consent decree. More detail on our specific obligations under the proposed consent decree is available on the FTC's website at http://www.ftc.gov/os/adjpro/d9310/040715do.pdf.

If the FTC rejects the proposed consent decree it would likely return the case to litigation. An administrative law judge would adjudicate the complaint in a trial-type proceeding. We are uncertain as to the length of the proceeding, but it could last in excess of a month. After the presentation of all of the evidence, the administrative law judge would issue a written opinion. The timing of the issuance of the opinion is uncertain and could take up to several months after the proceeding is concluded. Any decision of the administrative law judge may be appealed to the Commissioners of the FTC by either the FTC staff or us. If a majority of the FTC Commissioners were to determine that we violated applicable law, we would have the right to appeal to a U.S. Court of Appeals. Appeals to U.S. Courts of Appeals are often lengthy proceedings and generally extend for a year or two. The FTC staff and we would have the right to petition the U.S. Supreme Court for review of any Court of Appeals decision. The Supreme Court accepts very few cases each year, and it is uncertain whether they would accept our case for review.

If the FTC were to prevail in this challenge, it could seek to impose a wide variety of remedies, any of which would have a material adverse effect on our ability to continue to operate under our current business plans and on our results of operations. These potential remedies include the divestiture of Hyprotech, as well as mandatory licensing of Hyprotech software products and other engineering software products to one or more of our competitors. As of the filing date of this report, we have accrued $17.9 million to cover the cost of (1) professional service fees associated with our cooperation in the FTC's investigation since its commencement on June 7, 2002, and (2) estimated future professional services fees relating to the initial proceeding and our preparation in advance of such proceeding.

Litigation

On May 31, 2002, we acquired the capital stock of Hyprotech from AEA Technology plc. AEA is engaged in arbitration proceedings in England over a contract dispute with KBC Advanced Technologies PLC, an English technology and consulting services company. The dispute remains in arbitration and concerns alleged breaches by each party of an agreement to develop and market a product known as HYSYS.Refinery. We indemnified AEA under the Sale and Purchase Agreement with AEA dated May 10, 2002 against any costs, damages or expenses in respect of a claim brought by KBC alleging damages due to AEA's (a) failure to comply with its contractual obligations after the acquisition, (b) breach of non-competition clauses with respect to activities occurring after the acquisition, (c) breach of certain obligations to KBC under its agreement by virtue of the acquisition, or (d) execution of the acquisition agreement. On March 31, 2003, the arbitrator delivered a partial decision in the arbitration, as a result of which we have not received any request under the indemnification agreement, nor do we expect to receive one. On April 22, 2004 the arbitrator delivered a further partial decision stating that (a) the contract between AEA and KBC had been terminated and that AEA and Hyprotech were in breach of the non-compete provisions contained in that agreement, and (b) for a period of three years from the date of the award, Hyprotech shall not directly or indirectly sell or market a product which competes with HYSYS.Refinery. A further hearing is scheduled for December 2004, at which the arbitrator will determine whether there has been a breach

by Hyprotech of obligations relating to confidentiality. We believe that no such breach occurred. We are working with AEA in the resolution of this matter. It is too early to determine the likely outcome of this matter.

In addition, on September 11, 2002, KBC filed a separate complaint in state district court in Houston, Texas against us and Hyprotech. KBC's claim alleges tortious interference with contract and existing business relations, tortious interference with prospective business relationships, conversion of intellectual property and civil conspiracy. KBC has requested actual and exemplary damages, costs and interest. We believe the causes of action to be without merit and will defend the case vigorously. Also, we have filed a counterclaim against KBC requesting actual and punitive damages and attorney fees. A trial date has been set for January 19, 2004. On August 25, 2003, KBC filed an additional complaint in the state district court in Houston, Texas against us and Hyprotech alleging breach of non-compete provisions and requesting injunctive relief preventing sale of our product Aspen RefSYS. We believe the causes of action to be without merit and will defend the case vigorously. On September 15, 2003, the court set aside the application for injunction pending resolution of the arbitration in London. Following the London arbitrator's award of April 22, 2004 in relation to the non-compete, on May 7, 2004, the Houston court agreed to enter a judgment in Texas against Hyprotech on exactly the same terms as the arbitrator's award against Hyprotech. The Houston court further stated that KBC may not bring any further claims against Hyprotech in Houston and that all such claims are reserved for the arbitrator in London. KBC has applied to the Houston court to have re-instated its application for injunctive relief against the Company. A hearing is scheduled for September 15, 2004 in Houston to resolve KBC's application. As of the filing date of this report, we have accrued $5.9 million to cover the cost of (1) professional service fees associated with our legal defense since its commencement and (2) estimated future costs relating to the matter.

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

No matter was submitted to a vote of our security holders during the fourth quarter of fiscal 2004.

Dividends

We have never declared or paid cash dividends on our common stock.

In addition, under the terms of our January 2003 loan arrangement with Silicon Valley Bank, we are prohibited from paying any dividends on our stock, with the exception of dividends paid in common stock or dividends on our preferred stock paid in cash, provided that we are not in default under the loan arrangement. Any future determination relating to our dividend policy will be made at the discretion of our board of directors and will depend on a number of factors, including our future earnings, capital requirements, financial condition and future prospects and such other factors as the board of directors may deem relevant.

Under this statement, goodwill and certain other intangible assets determined to have an indefinite life were no longer amortized as of the date of adoption. General and administrative costs for the years ended June 30, 2000 and 2001 include amortization of goodwill and acquired assembled workforce of $0.9 million and $2.6 million, respectively.

Service and other revenues and cost of service and other for the year ended June 30, 2000 do not reflect a reclassification for the reimbursement of out-of-pocket expenses, as required by Emerging Issues Task Force Issue No. 01-14, "Income Statement Characterization of Reimbursements Received for "Out-of-Pocket' Expenses Incurred". It is impracticable to do so, as the information was not compiled during this period. The amounts included in service and other revenues and cost of service and other for the years ended June 30, 2001, 2002, 2003 and 2004 were $16.3 million, $18.8 million, $19.0 million and $16.9 million, respectively.

Basic and diluted net income (loss) per share and weighted average shares outstanding in the preceding table have been computed as described in note 2(i) to the consolidated financial statements included elsewhere in this Form 10-K. We have never declared or paid cash dividends on our common stock.

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

Overview

Since our founding in 1981, we have developed and marketed software and services to companies in the process industries. In addition to internally generated growth, we have acquired a number of businesses, including Hyprotech on May 31, 2002. We acquired Hyprotech in a transaction accounted for as a purchase. Our operating results include the operating results of Hyprotech only for periods subsequent to the date of acquisition.

We typically license our engineering solutions for terms of three to five years and license our manufacturing/supply chain solutions for terms of 99 years. See "Item 1. Business—Products: Software and Services."

Software license revenues, including license renewals, consists principally of revenues earned under fixed-term and perpetual software license agreements and is generally recognized upon shipment of the software if collection of the resulting receivable is probable, the fee is fixed or determinable, and vendor-specific objective evidence, or VSOE, of fair value exists for all undelivered elements. We determine VSOE based upon the price charged when the same element is sold separately. Maintenance and support VSOE represents a consistent percentage of the license fees charged to customers. Consulting services VSOE represents standard rates, which we charge our customers when we sell our consulting services separately. For an element not yet being sold separately, VSOE represents the price established by management having the relevant authority when it is probable that the price, once established, will not change before the separate introduction of the element into the marketplace. Revenues under license arrangements, which may include several different software products and

services sold together, are allocated to each element based on the residual method in accordance with American Institute of Certified Public Accountants, Statement of Position, or SOP, 98-9, "Software Revenue Recognition, with Respect to Certain Transactions." Under the residual method, the fair value of the undelivered elements is deferred and subsequently recognized when earned. We have established sufficient VSOE for professional services, training and maintenance and support services. Accordingly, software license revenues are recognized under the residual method in arrangements in which software is licensed with professional services, training and maintenance and support services. We use installment contracts as a standard business practice and have a history of successfully collecting under the original payment terms without making concessions on payments, products or services.

Maintenance and support services revenues are recognized ratably over the life of the maintenance and support contract period. Maintenance and support services include telephone support and unspecified rights to product upgrades and enhancements. These services are typically sold for a one-year term and are sold either as part of a multiple element arrangement with software licenses or are sold independently at time of renewal. We do not provide specified upgrades to our customers in connection with the licensing of our software products.

Service revenues from fixed-price contracts are recognized using the proportional performance method, measured by the percentage of costs (primarily labor) incurred to date as compared to the estimated total costs (primarily labor) for each contract. When a loss is anticipated on a contract, the full amount thereof is provided currently. Service revenues from time-and-expense contracts and consulting and training revenues are recognized as the related services are performed. Services that have been performed but for which billings have not been made are recorded as unbilled services, and billings that have been recorded before the services have been performed are recorded as unearned revenue in the accompanying consolidated balance sheets. In accordance with the Emerging Issues Task Force Issue No. 01-14, "Income Statement Characterization of Reimbursements Received for "Out-of-Pocket' Expenses Incurred," reimbursement received for out-of-pocket expenses is recorded as revenue and not as a reduction of expenses.

We license our software in U.S. dollars and several foreign currencies. We hedge material foreign currency-denominated installments receivable with specific hedge contracts in amounts equal to those installments receivable. Historically, we experience minor foreign currency exchange gains or losses due to foreign exchange rate fluctuations, the impact of which have typically not been material. We do not expect fluctuations in foreign currencies to have a significant impact on either our revenues or our expenses in the foreseeable future.

Significant Events—Year ended June 30, 2004

On August 14, 2003, we issued and sold 300,300 shares of Series D-1 preferred. We also delivered cash and 63,064 shares of Series D-2 preferred in consideration for the surrender of all of our outstanding Series B preferred. Each share of Series D preferred is currently convertible, at the holder's option, into 100 shares of our common stock and may be converted into additional shares of our common stock upon certain events as a result of antidilution provisions in our charter. In addition, we issued WD warrants to purchase up to 7,267,286 shares of common stock at a purchase price of $3.33 per share, and exchanged existing warrants to purchase 791,044 shares of common stock for WB warrants to purchase 791,044 shares of common stock at a purchase price of $4.08 per share.

During fiscal 2004, we used proceeds from the Series D financing and the sale of installments receivable to repurchase and retire $29.5 million of our convertible debentures. In addition, we also paid $8.2 million to settle our remaining obligation to Accenture.

In December 2003, we executed a Non-Recourse Receivables Purchase Agreement with Silicon Valley Bank, pursuant to which we have the ability to sell receivables to the bank through January 1, 2005. Under the terms of this agreement, the total outstanding balance of sold receivables may not exceed $35.0 million at any one time. We have agreed to act as the bank's agent for collection of the sold receivables.

In June 2004, we executed a plan to reduce our operating costs, primarily involving the closure of certain facilities. This resulted in a restructuring charge totaling $15.9 million, included in restructuring charges and FTC legal costs (as described below).

Summary of Restructuring Accruals

Fiscal 2004

In June 2004, we initiated a plan to reduce our operating expenses in order to better align our operating cost structure with the current economic environment and to improve our operating margins. The plan to reduce operating expenses resulted in the consolidation of facilities, headcount reductions, and the termination of operating contracts. These actions resulted in an aggregate restructuring charge of $23.8 million, recorded in the fourth quarter of fiscal 2004.

As of June 30, 2004, there was $13.3 million remaining in accrued expenses relating to the remaining severance obligations and lease payments. During the year ended June 30, 2004, the following activity was recorded (in thousands):

	Closure/ Consolidation of Facilities and Contract exit costs			Employee Severance, Benefits, and Related Costs			Asset Impairments			Total
Restructuring charge	$	20,984		$	1,046		$	1,776		$	23,806

Expected final payment date		February 2007			December 2004

Fiscal 2003

In October 2002, we initiated a plan to further reduce operating expenses in response to first quarter revenue results that were below expectations and to general economic uncertainties. In addition, we revised revenue expectations for the remainder of the fiscal year and beyond, primarily related to the manufacturing/supply chain product line, which has been affected the most by the current economic conditions. The plan to reduce operating expenses resulted in headcount reductions, consolidation of facilities, and discontinuation of development and support for certain non-critical products. These actions resulted in an aggregate restructuring charge of $16.1 million, recorded during the three months ended December 31, 2002. In June 2003 we reviewed our estimates to this plan and recorded a $12.0 million increase to the accrual, primarily due to revisions of the facility sub-lease assumptions, as well as increases to severance and other costs. During fiscal 2004, we recorded a $0.8 decrease to the accrual related to revised assumptions associated with lease exit costs and severance obligations, and recorded a payment of $4.1 million associated with the buyout of a remaining lease obligation.

As of June 30, 2004, there was $7.7 million remaining in accrued expenses relating to the remaining severance obligations and lease payments. During the year ended June 30, 2004, the following activity was recorded (in thousands):

		Closure/ Consolidation of Facilities			Employee Severance, Benefits, and Related Costs			Impairment of Assets and Disposition costs			Total
Accrued expenses, June 30, 2003		$	13,799		$	2,731		$	1,580		$	18,110

Expected final payment date			December 2010			April 2005			April 2005

Fiscal 2002

In the fourth quarter of fiscal 2002, we initiated a plan to reduce operating expenses and to restructure operations around our two primary product lines, engineering software and manufacturing/supply chain software. We reduced worldwide headcount by approximately 10%, or 200 employees, closed and consolidated facilities, and disposed of certain assets, resulting in an aggregate restructuring charge of $14.4 million. During fiscal 2004, we recorded a $0.8 decrease to the accrual related to revised assumptions associated with lease exit costs and severance obligations, and recorded a payment of $0.7 million associated with the buyout of a remaining lease obligation. As of June 30, 2004, there was $2.0 million remaining in accrued expenses relating to the remaining severance obligations and lease payments. During the year ended June 30, 2004, the following activity was recorded (in thousands):

		Closure/ Consolidation of Facilities			Employee Severance, Benefits, and Related Costs			Total
Accrued expenses, June 30, 2003		$	4,206		$	1,688		$	5,894

Accrued expenses, June 30, 2004		$	1,827		$	130		$	1,957

Expected final payment date			December 2010			April 2005

Fiscal 2001

In the third quarter of fiscal 2001, the revenues realized were below expectations as customers delayed spending in the widespread slowdown in information technology spending and the deferral of late-quarter purchasing decisions. At that time, we also reduced our revenue expectations for the fourth quarter of fiscal year 2001 and for the fiscal year 2002. Based on the reduced revenue expectations, management evaluated the business plan and made significant changes, resulting in a restructuring plan for our operations. This restructuring plan included a reduction in headcount, a substantial decrease in

discretionary spending and a sharpening of our e-business focus to emphasize our marketplace solutions. The restructuring plan resulted in a pre-tax charge totaling $7.0 million. During June 2004, the remaining balance of the accrual was paid, as we executed a buy-out of our remaining lease obligation. During the year ended June 30, 2004, the following activity was recorded (in thousands):

		Closure/ Consolidation of Facilities
Accrued expenses, June 30, 2003		$	740
	Fiscal 2004 payments		(412	)

	Adjustment—Facility lease buyout		(328	)

Accrued expenses, June 30, 2004		$	—

Fiscal 1999

In the fourth quarter of fiscal 1999, we undertook certain actions to restructure our business. The restructuring resulted from a lower than expected level of license revenues which adversely affected fiscal year 1999 operating results. The license revenue shortfall resulted primarily from delayed decision making driven by economic difficulties among customers in certain of our core vertical markets. The restructuring plan resulted in a pre-tax restructuring charge totaling $17.9 million. As of June 30, 2004, there was $0.5 million remaining in the accrued expenses relating to the restructuring. During the year ended June 30, 2004, the following activity was recorded (in thousands):

		Closure/ Consolidation of Facilities

Critical Accounting Estimates and Judgments

Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of our financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures. We base our estimates on historical experience and various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. The significant accounting policies that we believe are the most critical to aid in fully understanding and evaluating our reported financial results include the following:

•: Revenue recognition for both software licenses and fixed-fee consulting services,
•: Impairment of long-lived assets, goodwill and intangible assets,
•: Accrual of legal fees associated with outstanding litigation,
•: Accounting for income taxes, and
•: Allowance for doubtful accounts.

Revenue Recognition—Software Licenses

We recognize software license revenue in accordance with SOP No. 97-2, "Software Revenue Recognition", as amended by SOP No. 98-4 and SOP No. 98-9, as well as the various interpretations and clarifications of those statements. These statements require that four basic criteria must be satisfied before software license revenue can be recognized:

•: persuasive evidence of an arrangement between ourselves and a third party exists;
•: delivery of our product has occurred;
•: the sales price for the product is fixed or determinable; and
•: collection of the sales price is probable.

Our management uses its judgment concerning the satisfaction of these criteria, particularly the criteria relating to the determination of whether the fee is fixed and determinable and the criteria relating to the collectibility of the receivables, particularly the installments receivable, relating to such sales. Should changes and conditions cause management to determine that these criteria are not met for certain future transactions, all or substantially all of the software license revenue recognized for such transactions could be deferred.

Revenue Recognition—Consulting Services

We recognize revenue associated with fixed-fee service contracts in accordance with the proportional performance method, measured by the percentage of costs (primarily labor) incurred to date as compared to the estimated total costs (primarily labor) for each contract. When a loss is anticipated on a contract, the full amount of the anticipated loss is provided currently. Our management uses its judgment concerning the estimation of the total costs to complete the contract, considering a number of factors including the experience of the personnel that are performing the services and the overall complexity of the project. We have a significant amount of experience in the estimation of the total costs to complete a contract and have not typically recorded material losses related to these estimates. We do not expect the accuracy of our estimates to change significantly in the future. Should changes and conditions cause actual results to differ significantly from management's estimates, revenue recognized in future periods could be adversely affected.

Impairment of Long-lived Assets, Goodwill and Intangible Assets

In accordance with Statement of Financial Accounting Standards, or SFAS, No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets," we review the carrying value of long-lived assets when circumstances dictate that they should be reevaluated, based upon the expected future operating cash flows of our business. These future cash flow estimates are based on historical results, adjusted to reflect our best estimate of future markets and operating conditions, and are continuously reviewed based on actual operating trends. Historically, actual results have occasionally differed from our estimated future cash flow estimates. In the future, actual results may differ materially from these estimates, and accordingly cause a full impairment of our long-lived assets.

In accordance with SFAS No. 142, "Goodwill and Other Intangible Assets," we conduct at least an annual assessment on January 1st of the carrying value of our goodwill assets. We obtain a third-party valuation of the reporting units associated with the goodwill assets, which is based on either estimates of future income from the reporting units or estimates of the market value of the units, based on comparable recent transactions. These estimates of future income are based upon historical results, adjusted to reflect our best estimate of future markets and operating conditions, and are continuously reviewed based on actual operating trends. Historically, actual results have occasionally differed from our estimated future cash flow estimates. In the future, actual results may differ materially from these

estimates. In addition, the relevancy of recent transactions used to establish market value for our reporting units is based on management's judgment.

During the year ended June 30, 2004, we recorded $4.2 million in charges related to the impairment of certain long-lived assets and technology related intangible and computer software development assets. The timing and size of future impairment charges involves the application of management's judgment and estimates and could result in the impairment of all or substantially all of our long-lived assets, intangible assets and goodwill, which totaled $73.4 million as of June 30, 2004.

Accrual of Legal Fees Associated with Outstanding Litigation

We accrue estimated future legal fees associated with outstanding litigation for which management has determined that it is probable that a loss contingency exists. This requires management to estimate the amount of legal fees that will be incurred in the defense of the litigation. These estimates are based heavily on our expectations of the scope, length to complete and complexity of the claims. Historically, as these factors have changed after our original estimates, we have adjusted our estimates accordingly. In the future, additional adjustments may be recorded as the scope, length or complexity of outstanding litigation changes.

Accounting for Income Taxes

As part of the process of preparing our consolidated financial statements we are required to estimate our income taxes in each of the jurisdictions in which we operate. This process involves estimating our actual current tax liabilities together with the assessment of temporary differences resulting from differing treatment of items, such as deferred revenue, for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within our consolidated balance sheet. Tax assets also result from net operating losses, research and development tax credits and foreign tax credits. We must then assess the likelihood that our deferred tax assets will be recovered from future taxable income and to the extent we believe that recovery is not likely, we must establish a valuation allowance. To the extent we establish a valuation allowance or increase or decrease this allowance in a period, the impact will be included in the tax provision in our statement of operations.

Significant management judgment is required in determining our deferred tax assets and liabilities and any valuation allowance recorded against these amounts. The valuation allowance is based on our estimates of taxable income by jurisdiction in which we operate and the period over which our deferred tax assets will be recoverable. In the event that actual results differ from these estimates or we adjust these estimates in future periods we may need to establish an additional valuation allowance which could result in a tax provision equal to the carrying value of our deferred tax assets. During the year ended June 30, 2004, we recorded a $14.6 million valuation allowance against our U.S. domiciled net deferred tax assets. This charge, however, had no impact on our cash flows.

Allowance for Doubtful Accounts

We make judgments as to our ability to collect outstanding receivables and provide allowances for the portion of receivables for which collection is doubtful. Provisions are made based upon a specific review of all significant outstanding invoices. In determining these provisions, we analyze our historical collection experience and current economic trends. If the historical data we use to calculate the allowance provided for doubtful accounts do not reflect the future ability to collect outstanding receivables, additional provisions for doubtful accounts may be required for all or substantially all of certain receivable balances.

Comparison of Fiscal 2004 to Fiscal 2003

Revenues. Revenues are derived from software licenses, consulting services and maintenance and training. Total revenues for fiscal 2004 increased 0.9% to $325.7 million from $322.7 million in fiscal 2003. Total revenues from customers outside the United States were $186.5 million or 57.3% of total revenues and $172.5 million or 53.5% of total revenues for fiscal 2004 and 2003, respectively. The geographical mix of revenues can vary from period to period.

Software license revenues represented 46.8% and 43.3% of total revenues for fiscal 2004 and 2003, respectively. Revenues from software licenses in fiscal 2004 increased 8.9% to $152.3 million from $139.9 million in fiscal 2003. Software license revenues are attributable to software license renewals covering existing users, the expansion of existing customer relationships through licenses covering additional users, licenses of additional software products, and, to a lesser extent, to the addition of new customers. This increase is primarily due to a modest increase in demand for products from our manufacturing/supply chain product line, as well as a modest increase in revenues from our customers

in the chemical manufacturing industry. For fiscal 2004, approximately 70% and 30% of our license revenue was derived from products in the engineering product line and manufacturing/supply chain product line, respectively, as compared to approximately 75% and 25%, respectively, in fiscal 2003.

Revenues from service and other consist of consulting services, post-contract support on software licenses, training and sales of documentation. Revenues from service and other for fiscal 2004 decreased 5.2% to $173.4 million from $182.9 million for fiscal 2003. This decrease is attributable primarily to the consulting services business. Consulting services decreased due to a year over year $2.1 million decline in reimbursable expenses, and due to the general low-level of licenses of our manufacturing/supply chain products during the two most recent fiscal years. Our consulting services are more heavily linked to the implementation of our manufacturing/supply chain products than they are to our engineering products.

Cost of Software Licenses. Cost of software licenses consists of royalties, amortization of previously capitalized software costs, costs related to delivery of software, including disk duplication and third-party software costs, printing of manuals and packaging. Cost of software licenses for fiscal 2004 increased 11.9% to $15.6 million from $13.9 million in fiscal 2003. Cost of software licenses as a percentage of revenues from software licenses increased to 10.2% for fiscal 2004 from 10.0% for fiscal 2003. The cost increase is primarily due to an increase in royalty costs of $0.9 million and amortization of computer software development costs of $0.9 million. The increase in royalties is attributable to higher license revenues and the increase in the amortization of computer software development costs is due to two significant product releases, AES 12.1 and AMS 6.0, during the first part of this fiscal year.

Cost of Service and Other. Cost of service and other consists of the cost of execution of application consulting services, technical support expenses and the cost of training services. Cost of service and other for fiscal 2004 decreased 7.0% to $99.4 million from $106.9 million for fiscal 2003. Cost of service and other, as a percentage of revenues from service and other, decreased to 57.3% for fiscal 2004 from 58.4% for fiscal 2003. The decrease in cost is primarily due to decreased payroll costs of $2.5 million related to reductions in headcount, as well as a decrease in reimbursable expenses of $2.1 million. The costs of service and other as a percentage of service and other revenues are generally consistent from period to period, showing a modest decrease as our utilization rates have increased.

Amortization of Technology Related Intangible Assets. Amortization of technology related intangible assets consists of the amortization from intangible assets obtained in acquisitions. These assets are generally being amortized over a period of three to five years. Amortization expense for fiscal 2004 decreased 11.5% to $7.3 million from $8.2 million for fiscal 2003. The decrease is primarily due to the discontinued amortization of $5.3 million of intangible assets for which an impairment was recorded in the three months ended December 31, 2002.

Impairment of Technology Related Intangible and Computer Software Development Assets. Impairment of technology related intangible and computer software development assets consists of impairment charges related to assets that are directly involved in the production of revenue. In the fourth quarter of fiscal 2004, we recorded an impairment charge of $3.3 million related to management's decision to discontinue development of certain next generation manufacturing supply chain products. Management's decision was based on concerns about the future revenue projections for these products, and the assessment of costs remaining to bring these products to market. In fiscal 2003, we recorded an impairment charge of $8.7 million related to computer software development costs and intangible assets that were related to products that management had decided would not be sold or determined that their carrying values were in excess of their fair values. The assets that will no longer be used were identified by management's decisions to either discontinue future development efforts associated with certain products. The carrying values of the remaining assets were compared to the fair values of those assets resulting in an impairment. The fair values were determined by forecasting the future net cash flows associated with the products.

Selling and Marketing. Selling and marketing expenses for fiscal 2004 decreased 6.0% to $99.5 million from $105.9 million for fiscal 2003, while decreasing as a percentage of total revenues to 30.6% from 32.8%. The decrease is primarily due to a decrease in advertising costs of $5.0 million related to AspenWorld, which took place in fiscal 2003, and a decrease in payroll and benefit costs of $0.8 million attributable to the headcount reductions effected in the October 2002 restructuring plan.

Research and Development. Research and development expenses consist of personnel and outside consultancy costs required to conduct our product development efforts. Research and development expenses for fiscal 2004 decreased 9.2% to $59.1 million from $65.1 million for fiscal 2003, and decreased as a percentage of total revenues to 18.2% from 20.2%. The decrease is primarily attributable to a $1.7 million decrease in depreciation and amortization related to assets written-off in December 2002, a $1.0 million decrease in salary and benefit costs associated with the reductions in headcount from the October 2002 restructuring plan, a $1.0 million decrease in consulting costs, and a $0.7 million decrease in travel costs.

We capitalized software development costs that amounted to 11.4% of our total research and development costs during fiscal 2004, as compared to 14.6% in fiscal 2003. These percentages will vary from quarter to quarter, depending upon the stage of development for the various projects in a given period. This decrease is primarily due to the completion of product development activity related to two significant product releases during the first part of fiscal 2004.

General and Administrative. General and administrative expenses consist primarily of salaries of administrative, executive, financial and legal personnel, outside professional fees and amortization of identifiable intangibles. General and administrative expenses for fiscal 2004 increased 11.4% to $31.7 million from $28.5 million for fiscal 2003, and increased as a percentage of total revenues to 9.7% from 8.8%. This increase is due to a $6.5 million increase in legal costs associated with legal defense and loss contingencies associated with the KBC litigation and with the settlement of other litigation. This is offset by a $3.0 million decrease in salary and benefit costs associated with the reductions in headcount from the October 2002 restructuring plan.

Long Lived Asset Impairment Charges. In fiscal 2004, this amount consisted of $1.0 million in impairment charges based on our decisions to discontinue certain internal capital projects that had previously been put on hold. In addition, certain fixed assets that supported research and development efforts were considered impaired as a result of the product consolidation decisions made in the April 2004 product review. In October 2002, we determined that the goodwill should be tested for impairment as a result of lowered revenue expectations and the overall decline in our market value. This amounted to a $74.7 million aggregate impairment charge, recorded in the fiscal 2003 accompanying consolidated statement of operations. Concurrent with the goodwill impairment review, we determined that several other assets were also impaired. This resulted in an additional $31.4 million in impairment charges in fiscal 2003, related to the intellectual property purchased from Accenture in February 2002, internal capital projects and fixed assets.

Restructuring Charges and FTC Legal Costs. During fiscal 2004, we recorded $20.8 million in restructuring charges and FTC legal costs. Of this amount, $23.8 million is associated with a June 2004 restructuring plan, which is offset by $7.9 million in adjustments to prior restructuring accruals and deferred rent balances, and $4.9 million is FTC legal costs, related to the FTC challenge of our acquisition of Hyprotech.

In June 2004, we initiated a plan to reduce our operating expenses in order to better align our expense structure with the current economic environment and to improve our operating margins. This plan coincided with a reduction in our revenue projections for fiscal 2005. The plan to reduce operating expenses resulted in the consolidation of facilities, headcount reductions, and the termination of operating contracts. These actions resulted in an aggregate restructuring charge of $23.8 million. This is

offset by $7.9 million in adjustments to the prior restructuring accruals and deferred rent balances, primarily related to the buy-out of the remaining obligation for our Houston facility, of which portions had previously been vacated and included in previous restructuring plans. The components of the restructuring plan are as follows:

Closure/consolidation of facilities: Approximately $21.0 million of the restructuring charge relates to the termination of facility leases and other lease related costs. The facility leases had remaining terms ranging from several months to eight years. The amount accrued is an estimate of the remaining obligation under the lease or actual costs to buy-out leases, reduced by expected income from the sublease of the underlying properties.

Employee severance, benefits and related costs: Approximately $1.0 million of the restructuring charge relates to the reduction in headcount. Approximately 35 employees, or 2% of the workforce, were eliminated under the restructuring plan. A majority of the employees were located in North America, although Europe was affected, as well. All business units were affected, including services, sales and marketing, research and development, and general and administrative.

Impairment of assets: Approximately $1.8 million of the restructuring charge relates to charges associated with the impairment of fixed assets associated with the closed/consolidated facilities. These assets were reviewed for impairment in accordance with SFAS No. 144, and were considered to be impaired because their carrying values were in excess of their fair values. The fair values were determined based on a quoted market price from a third party.

Interest Income. Interest income is generated from investment of excess cash in short-term investments and from the license of software pursuant to installment contracts. Under these installment contracts, we offer a customer the option to make annual payments for its term licenses instead of a single license fee payment at the beginning of the license term. Historically, a substantial majority of the asset optimization customers have elected to license these products through installment contracts. Included in the annual payments is an implicit interest rate established by us at the time of the license. As we sell more perpetual licenses for value chain solutions, these sales are being paid for in forms that are generally not installment contracts. If the mix of sales moves away from installment contracts, interest income in future periods will be reduced.

We sell a portion of the installment contracts to unrelated financial institutions. The interest earned by us on the installment contract portfolio in any one year is the result of the implicit interest rate established by us on installment contracts and the size of the contract portfolio. Interest income was $7.4 million for fiscal 2004 as compared to $8.5 million in fiscal 2003. This decrease primarily is due to the aggressive collection of receivables and the increased sale of receivables, resulting in the decrease of installments receivable balance.

Interest Expense. Interest expense was incurred under our convertible debentures, amounts owed to Accenture, and capital lease obligations. Interest expense in fiscal 2004 decreased to $4.9 million from $7.1 million in fiscal 2003. This decrease in interest expense results from the elimination of interest bearing debt, such as the payment of the obligation to Accenture in August 2003 and the repurchase and retirement of a portion of the convertible debentures in September 2003, January 2004, March 2004 and May 2004.

Foreign currency exchange gain (loss). Foreign currency exchange gains and losses are primarily incurred through the revaluation of receivables denominated in foreign currencies. In fiscal 2004 we recorded a foreign currency exchange gain of $0.4 million, compared to a $0.1 million loss in fiscal 2003. This increase was due to favorable exchange rate fluctuations and effective hedging of foreign receivable balances.

Income (Loss) on Equity in Joint Ventures and Realized Gain (Loss) on Sales of Assets. Income (loss) on equity in joint ventures and realized gain (loss) on sales of assets was a $0.5 million gain in fiscal 2004 as compared to $0.5 million loss in fiscal 2003. This increase is due primarily to a $0.5 million gain on the sale of receivables and a $0.2 million gain on the sale of land in Houston, Texas.

Provision for/Benefit from Income Taxes. We recorded a provision for income taxes of $20.2 million for fiscal 2004. The provision for fiscal 2004 includes a $14.6 million valuation allowance against U.S. domiciled net deferred tax assets and a $5.6 million provision primarily related to foreign taxes. We provided a full valuation allowance against the net operating losses generated during fiscal 2003 and 2004.

Under SFAS No. 109, a deferred tax asset related to the future benefit of a tax loss carryforward should be recorded unless we make a determination that it is "more likely than not" that such deferred tax asset would not be realized. Accordingly, a valuation allowance would be provided against the deferred tax asset to the extent that we cannot demonstrate that it is "more likely than not" that the deferred tax asset will be realized. In determining the amount of valuation allowance required, we consider numerous factors, including historical profitability, estimated future taxable income, the volatility of the historical earnings, and the volatility of earnings of the industry in which we operate. We periodically review our deferred tax asset to determine if such asset is realizable. In fiscal 2004, we concluded, in accordance with SFAS No. 109, that we should record a valuation allowance on a significant portion of our deferred tax asset under the "more likely than not" test and therefore increased the amount of the valuation allowance. See Note 10 of Notes to Consolidated Financial Statements.

Comparison of Fiscal 2003 to Fiscal 2002

Revenues. Total revenues for fiscal 2003 increased 0.7% to $322.7 million from $320.6 million in fiscal 2002. Total revenues from customers outside the United States were $172.5 million or 53.5% of total revenues and $146.9 million or 45.8% of total revenues for fiscal 2003 and 2002, respectively. The geographical mix of revenues can vary from period to period.

Software license revenues represented 43.3% and 41.8% of total revenues for fiscal 2003 and 2002, respectively. Revenues from software licenses in fiscal 2003 increased 4.4% to $139.9 million from $133.9 million in fiscal 2002. Greater software license revenues in fiscal 2003 were driven by the inclusion of software license revenue associated with Hyprotech, offset by an overall decline in demand for our manufacturing/supply chain products. Revenues and expenses associated with Hyprotech are included in our results from operations from the May 31, 2002 date of acquisition; for fiscal 2002 this includes the month of June 2002 and for fiscal 2003 this includes the full fiscal year.

Revenues from service and other for fiscal 2003 decreased 2.1% to $182.9 million from $186.7 million for fiscal 2002. This decline in revenue is reflective of a decrease in consulting revenue, partially offset by the inclusion of maintenance revenue associated with Hyprotech. The decline in consulting revenue primarily is related to the decline in demand for our manufacturing/supply chain software products, along with which we typically sell consulting projects.

Cost of Software Licenses. Cost of software licenses for fiscal 2003 increased 17.6% to $13.9 million from $11.8 million in fiscal 2002. Cost of software licenses as a percentage of revenues from software licenses increased to 10.0% for fiscal 2003 from 8.8% for fiscal 2002. These increases are primarily the result of a $3.3 million increase in royalties, primarily related to a royalty arrangement with Accenture, which was effective as of the beginning of fiscal 2003, under which we pay royalties on the licensing of certain manufacturing/supply chain products.

Cost of Service and Other. Cost of service and other for fiscal 2003 decreased 10.9% to $106.9 million from $120.0 million for fiscal 2002. Cost of service and other, as a percentage of

revenues from service and other, decreased to 58.4% for fiscal 2003 from 64.3% for fiscal 2002. This decrease in absolute dollars is due to a decrease in consulting costs of $3.5 million and a decrease in salary and related costs of $4.5 million related to the reductions in headcount reflected in the restructuring charges of May 2002 and October 2002. The decrease as a percentage of service and other revenues was due to the headcount reductions, as well as the increase of revenues from software maintenance as a percentage of service and other revenue, a service that provides higher margins than consulting services.

Amortization of Technology Related Intangible Assets. Amortization expense for fiscal 2003 increased 38.7% to $8.2 million from $5.0 million for fiscal 2002. The increase is primarily due to the intangible assets acquired as part of the Hyprotech acquisition in May 2002.

Impairment of technology related intangible and computer software development assets. In fiscal 2003, we recorded an impairment charge of $8.7 million related to computer software development costs and intangible assets that were related to products that management had decided would not be sold or determined that their carrying values were in excess of their fair values. The assets that will no longer be used were identified by management's decisions to either discontinue future development efforts associated with certain products. The carrying values of the remaining assets were compared to the fair values of those assets resulting in an impairment. The fair values were determined by forecasting the future net cash flows associated with the products. In fiscal 2002, we recorded an impairment charge of $1.2 million related to prepaid royalty fees associated with a discontinued product.

Selling and Marketing. Selling and marketing expenses for fiscal 2003 decreased 8.1% to $105.9 million from $115.2 million for fiscal 2002, while decreasing as a percentage of total revenues to 32.8% from 35.9%. The decreases are attributable to salary and related costs of $8.2 million associated with the headcount reductions reflected in the restructuring charges of May 2002 and October 2002, and $2.6 million associated with travel and entertainment costs, partially offset by $4.9 million in costs associated with our October 2002 AspenWorld conference, which occurs bi-annually, the inclusion of costs associated with Hyprotech, increases in certain foreign-based sales expenses where currencies strengthened as compared to the US dollar, and an increase in sales commissions related to significantly higher license revenues in the three months ended September 30, 2002 as compared to the three months ended September 30, 2001.

Research and Development. Research and development expenses for fiscal 2003 decreased 12.6% to $65.1 million from $74.5 million for fiscal 2002, and decreased as a percentage of total revenues to 20.2% from 23.2%. These decreases are attributable to a $4.5 million decrease in salary and related costs related to the effect of reductions in headcount reflected in the restructuring charges of May 2002 and October 2002, partially offset by the inclusion of costs associated with Hyprotech and increases in certain foreign-based research and development expenses where currencies strengthened as compared to the US dollar.

We capitalized software development costs that amounted to 14.6% of our total research and development costs during fiscal 2003, as compared to 11.7% in fiscal 2002. This increase is due to product development activity related to the Accenture co-development alliance, as well as a smaller level of overall research and development spending.

General and Administrative. General and administrative expenses for fiscal 2003 decreased 2.6% to $28.5 million from $29.2 million for fiscal 2002, and decreased as a percentage of total revenues to 8.8% from 9.1%. These decreases are due to a $2.4 million decrease in salary and related costs related to the reductions in headcount reflected in the restructuring charges of May 2002 and October 2002, offset by increases to our bad debt reserve and the inclusion of general and administrative costs associated with Hyprotech.

Long Lived Asset Impairment Charges. In October 2002, we determined that the goodwill should be tested for impairment as a result of lowered revenue expectations and the overall decline in our market value. This amounted to a $74.7 million aggregate impairment charge, recorded in the fiscal 2003 accompanying consolidated statement of operations. Concurrent with the goodwill impairment review, we determined that several other assets were also impaired. This resulted in an additional $31.4 million in impairment charges in fiscal 2003, related to the intellectual property purchased from Accenture in February 2002, internal capital projects and fixed assets.

Restructuring Charges and FTC Legal Costs. During fiscal 2003, we recorded $41.1 million in restructuring charges and FTC legal costs. Of this amount, $28.1 million is associated with an October 2002 restructuring plan, and $13.0 million is FTC legal costs. In October 2002, we initiated a plan to further reduce operating expenses in response to first quarter revenue results that were below expectations and to general economic uncertainties. In addition, we revised revenue expectations for the remainder of the fiscal year and beyond, primarily related to the manufacturing/supply chain product line, which had been affected the most by the current economic conditions. The plan to reduce operating expenses resulted in headcount reductions, consolidation of facilities, and discontinuation of development and support for certain non-critical products. These actions resulted in an aggregate restructuring charge of $16.1 million, recorded during the three months ended December 31, 2002. In June 2003 we reviewed our estimates to this plan and recorded a $12.0 million increase to the accrual, primarily due to revisions of the facility sub-lease assumptions, as well as increases to severance and other costs.

Interest Income. Interest income was $8.5 million for fiscal 2003 as compared to $6.8 million in fiscal 2002. This increase primarily is due to the increase of installment contracts associated with Hyprotech.

Interest Expense. Interest expense in fiscal 2003 increased to $7.1 million from $5.6 million in fiscal 2002. This increase primarily is due to interest on the amounts owed to Accenture.

Foreign currency exchange loss. Foreign currency exchange loss in fiscal 2003 decreased to $0.1 million from $1.1 million in fiscal 2002. This decrease was due to the implementation of a more effective hedging policy for Hyprotech's receivables. In fiscal 2002, an effective hedging policy had not yet been implemented.

Income (Loss) on Equity in Joint Ventures and Realized Gain on Sales of Investments. Income (loss) on equity in joint ventures and realized gain on sales of investments was a $0.5 million loss in fiscal 2003 as compared to $0.2 million in income in fiscal 2002. The loss in fiscal 2003 is related to losses in the joint ventures, caused by the general economic slowdown during the year.

Provision for/Benefit from Income Taxes. We provided a full valuation against the foreign and domestic benefit generated during fiscal 2003 and recorded a provision for income taxes of $2.4 million for fiscal 2002. The provision for fiscal 2002 represents income taxes on income generated in certain foreign jurisdictions where we did not have operating loss carryforwards. We generated significant U.S. tax loss carryforwards during both fiscal 2003 and 2002. The provision for fiscal 2002 was comprised of an income tax provision related to foreign subsidiaries, a benefit from income taxes and an offsetting increase in the tax valuation.

Quarterly Results

Our operating results and cash flow have fluctuated in the past and may fluctuate significantly in the future as a result of a variety of factors, including purchasing patterns, timing of introductions of new solutions and enhancements by us and our competitors, and fluctuating economic conditions. Because license fees for our software products are substantial and the implementation of our solutions often requires the services of our engineers over an extended period of time, the sales process for our

solutions is lengthy and can exceed one year. Accordingly, software revenues are difficult to predict, and the delay of any order could cause our quarterly revenues to fall substantially below expectations. Moreover, to the extent that we succeed in shifting customer purchases away from point solutions and toward integrated solutions, the likelihood of delays in ordering may increase and the effect of any delay may become more pronounced.

We ship software products within a short period after receipt of an order and usually do not have a material backlog of unfilled orders of software products. Consequently, revenues from software licenses, including license renewals, in any quarter are substantially dependent on orders booked and shipped in that quarter. Historically, a majority of each quarter's revenues from software licenses has been derived from license agreements that have been consummated in the final weeks of the quarter. Therefore, even a short delay in the consummation of an agreement may cause revenues to fall below expectations for that quarter. Since our expense levels are based in part on anticipated revenues, we may be unable to adjust spending in a timely manner to compensate for any revenue shortfall and any revenue shortfall would likely have a disproportionately adverse effect on net income. We expect that these factors will continue to affect our operating results for the foreseeable future.

The following table presents selected quarterly consolidated statement of operations data for fiscal 2003 and 2004. These data are unaudited but, in our opinion, reflect all adjustments necessary for a fair presentation of these data in accordance with accounting principles generally accepted in the United States of America.

Liquidity and Capital Resources

In fiscal 2004, operating activities provided $40.7 million of cash primarily due to income from operations, excluding non-cash charges, our commitment to both the aggressive collection of receivables and the increased sale of receivables, partially offset by the continuing cash payments related to the ongoing proceedings in connection with the anti-trust claims filed by the FTC with respect to our acquisition of Hyprotech, and our previous restructuring charges. In fiscal 2002 and 2003, operating activities used $8.0 million and provided $21.6 million of cash, respectively.

In fiscal 2004, investing activities used $8.0 million of cash primarily as a result of the capitalization of computer software development costs and the ordinary purchases of property and equipment, partially offset by the proceeds from the sale of land in December 2003. In fiscal 2002 and 2003, investing activities used $102.3 million and provided $7.5 million of cash, respectively.

In fiscal 2004, financing activities provided $22.2 million of cash primarily due to the proceeds from the Series D financing, partially offset by pay-off of amounts owed to Accenture and repurchase and retirement of $29.5 million of the convertible debentures. In fiscal 2002 and 2003, financing activities provided $107.1 million and used $11.6 million of cash, respectively.

Historically, we have financed our operations principally through cash generated from public offerings of our convertible debentures and common stock, private offerings of our preferred stock and common stock, operating activities, and the sale of installment contracts to third parties.

In August 2003, we issued and sold 300,300 shares of Series D-1 preferred, along with WD warrants to purchase up to 6,006,006 shares of common stock, for an aggregate purchase price of $100.0 million. Concurrently, we paid $30.0 million and issued 63,064 shares of Series D-2 preferred, along with WB and WD warrants to purchase up to 1,261,280 shares of common stock, to repurchase all of the outstanding Series B preferred. The Series D preferred earns cumulative dividends at an annual rate of 8%, that are payable when and if declared by the board, in cash or, subject to certain conditions, common stock. Each share of Series D preferred currently is convertible into 100 shares of common stock, subject to anti-dilution and other adjustments. As a result, the shares of Series D preferred currently are convertible into an aggregate of 36,336,400 shares of common stock. The Series D preferred is subject to redemption at the option of the holders as follows: 50% on or after August 14, 2009 and 50% on or after August 14, 2010.

An aggregate of $45 million of working capital may be used to repay a portion of our convertible debentures at or prior to maturity. During the year ended June 30, 2004, we repurchased and retired a face value of $29.5 million of these convertible debentures.

Historically, we have had arrangements to sell long-term installments receivable to two financial institutions, General Electric Capital Corporation and Fleet Business Credit Corporation. These contracts represent amounts due over the life of existing term licenses. During fiscal 2002, 2003 and 2004, we sold $42.7 million, $66.7 million and $54.9 million of installments receivable, respectively. As of June 30, 2004, there was approximately $50 million in additional availability under the arrangements. We expect to continue to have the ability to sell installments receivable, as the collection of the sold receivables will reduce the outstanding balance, and the availability under the arrangements can be increased. At June 30, 2004, we had a partial recourse obligation that was within the range of $1.4 million to $4.1 million.

In December 2003, we executed a Non-Recourse Receivables Purchase Agreement with Silicon Valley Bank, pursuant to which we have the ability to sell receivables to the bank through January 1, 2005. Under the terms of this agreement the total outstanding balance of sold receivables may not exceed $35 million at any one time. We will act as the bank's agent for collection of the sold receivables. During the year ended June 30, 2004, we sold receivables for aggregate proceeds of $42.5 million under this agreement and as of June 30, 2004 there was $5.0 million in remaining

availability. We may in the future establish new arrangements to sell additional installment contracts to other financial institutions and increase our cash position.

In January 2003, we executed a Loan Arrangement with Silicon Valley Bank. This arrangement provides a line of credit of up to the lesser of (i) $15.0 million or (ii) 70% of eligible domestic receivables, and a line of credit of up to the lesser of (i) $10.0 million or (ii) 80% of eligible foreign receivables. The lines of credit bear interest at the bank's prime rate (4.00% at June 30, 2004). We are required to maintain a $4.0 million compensating cash balance with the bank, or be subject to an unused line fee and collateral handling fees. The lines of credit will initially be collateralized by nearly all of our assets, and upon achieving certain net income targets, the collateral will be reduced to a lien on our accounts receivable. We are required to meet certain financial covenants, including minimum tangible net worth, minimum cash balances and an adjusted quick ratio. As of June 30, 2004, there were $11.9 million in letters of credit outstanding under the line of credit, and there was $7.4 million available for future borrowing. On September 10, 2004, we executed an amendment to the Loan Arrangement that adjusted the terms of certain financial covenants, and cured a default of the tangible net worth covenant as of June 30, 2004. The Loan Arrangement expires in January 2005, and we are currently in negotiations with the bank to amend and extend the agreement.

As of June 30, 2004, we had cash and cash-equivalents totaling $107.7 million. Our commitments as of June 30, 2004 consisted primarily of the maturity of the convertible debentures on June 15, 2005, royalty commitments owed to Accenture, capital lease obligations, and leases on our headquarters and other facilities. Other than these, there were no other commitments for capital or other expenditures. Our obligations related to these items at June 30, 2004 are as follows (in thousands):

	2005		2006		2007		2008		2009		Thereafter		Total

We believe our current cash balances, availability of sales of our installment contracts, availability under the Silicon Valley Bank line of credit and cash flows from our operations will be sufficient to meet our working capital and capital expenditure requirements for at least the next 12 months. However, we may need to obtain additional financing thereafter or earlier, if our current plans and projections prove to be inaccurate or our expected cash flows prove to be insufficient to fund our operations because of lower-than-expected revenues, unanticipated expenses or other unforeseen difficulties, due to normal operations or FTC-related costs. In addition, we may seek to take advantage of favorable market conditions by raising additional funds from time to time through public or private security offerings, debt financings, strategic alliances or other financing sources. Our ability to obtain additional financing will depend on a number of factors, including market conditions, our operating performance and investor interest. These factors may make the timing, amount, terms and conditions of any financing unattractive. They may also result in our incurring additional indebtedness or accepting stockholder dilution. If adequate funds are not available or are not available on acceptable terms, we may have to forego strategic acquisitions or investments, reduce or defer our development activities, or delay our introduction of new products and services. Any of these actions may seriously harm our business and operating results.

Inflation

Inflation has not had a significant impact on our operating results to date and we do not expect inflation to have a significant impact during fiscal 2005.

New Accounting Pronouncements

In April 2003, the Financial Accounting Standards Board, or FASB, issued SFAS No. 149, "Amendment of Statement 133 on Derivative Instruments and Hedging Activities." This pronouncement amends and clarifies financial accounting and reporting for derivative instruments, including certain derivative instruments embedded in other contracts (collectively referred to as derivatives) and for hedging activities under SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities." The provisions of this statement are effective for transactions that are entered into or modified after June 30, 2003. The adoption of SFAS No. 149 did not have a material effect on our consolidated financial position or results of operations.

In January 2003, the FASB issued Interpretation No. 46 (FIN 46), "Consolidation of Variable Interest Entities," which clarifies the application of Accounting Research Bulletin No. 51, "Consolidated Financial Statements," relating to consolidation of certain entities. In December 2003 the FASB revised FIN 46. First, FIN 46 will require identification of our participation in variable interest entities (VIE), which are defined as entities with a level of invested equity that is not sufficient to fund future activities to permit them to operate on a stand alone basis, or whose equity holders lack certain characteristics of a controlling financial interest. For entities identified as VIE, FIN 46 sets forth a model to evaluate potential consolidation based on an assessment of which party to the VIE, if any, bears a majority of the exposure to its expected losses, or stands to gain from a majority of its expected returns. FIN 46 also sets forth certain disclosure regarding interests in VIE that are deemed significant, even if consolidation is not required. Certain provisions of FIN 46, as revised, relating to the consolidation of special-purpose entities are effective for periods ending after December 15, 2003. The adoption of these provisions did not have an impact on our financial position, results of operations or cash flows. The remaining provisions of FIN 46, as revised, relating to the consolidation or disclosure of all other VIE are effective for periods ending after March 15, 2004. The adoption of these provisions did not have an impact on our financial position, results of operations or cash flows.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

Information relating to quantitative and qualitative disclosure about market risk is set forth in notes 2(c), 2(d), 2(h), 2(j) and 11 to our consolidated financial statements included elsewhere in this Form 10-K and below under the captions "Investment Portfolio" and "Foreign Exchange Hedging."

Investment Portfolio

We do not use derivative financial instruments in our investment portfolio. We place our investments in instruments that meet high credit quality standards, as specified in our investment policy guidelines. In addition, we limit the amount of credit exposure to any one issuer and the types of instruments approved for investment. We do not expect any material loss with respect to our investment portfolio. The following table provides information about our investment portfolio. For investment securities, the table presents principal cash flows and related weighted average interest rates by expected maturity dates.

Impact of Foreign Currency Rate Changes

During fiscal 2004, the U.S. dollar weakened against currencies for countries in which we have local operations, primarily in Europe, Canada and the Asia-Pacific region. The translation of our foreign entities' assets and liabilities did not have a material impact on our consolidated operating results. Foreign exchange forward contracts are only purchased to hedge certain customer installments receivable amounts denominated in a foreign currency.

Foreign Exchange Hedging

We enter into foreign exchange forward contracts to reduce our exposure to currency fluctuations on customer installments receivable denominated in foreign currencies. The objective of these contracts is to limit the impact of foreign currency exchange rate movement on our operating results. We do not use derivative financial instruments for speculative or trading purposes. We had $19.9 million of foreign exchange forward contracts denominated in Japanese, British, Swiss, Singapore and Euro currencies which represented underlying customer installments receivable transactions at the end of fiscal 2004. At each balance sheet date, the foreign exchange forward contracts and the related installments receivable denominated in foreign currencies are revalued based on the current market exchange rates. Resulting gains and losses are included in earnings or deferred as a component of other comprehensive income. These deferred gains and losses are recognized in income in the period in which the underlying anticipated transaction occurs. Gains and losses related to these instruments for fiscal 2004 were not material to our financial position. We do not anticipate any material adverse effect on our consolidated financial position, operating results or cash flows resulting from the use of these instruments. There can be no assurance, however, that these strategies will be effective or that transaction losses can be limited or forecasted accurately.

The following table provides information about our forward contracts, at the end of fiscal 2004, to sell foreign currencies for U.S. dollars. All of these contracts relate to customer accounts and installments receivable. The table presents the value of the contracts in U.S. dollars at the contract exchange rate as of the contract maturity date. The average contract rate approximates the weighted

average contractual foreign currency exchange rate and the forward position in U.S. dollars approximates the fair value on the contract at the end of fiscal 2004.

Currency	Average Contract Rate	Forward Amount in U.S. Dollars		Contract Origination Date	Contract Maturity Date

Euro	0.84	$	10,431	Various: Oct 03-Jun 04	Various: Jul 04-Jul 05

In addition, in May 2002, as part of the acquisition of Hyprotech, we initiated loans with two of our foreign subsidiaries. The two loans, denominated in British pounds and Canadian dollars, were intended to be a natural hedge against foreign currency risk associated with installment receivable contracts acquired with Hyprotech that were denominated in a currency other than their functional currency. The loan denominated in British pounds was repaid in December 2003 and the loan denominated in Canadian dollars was repaid in January 2004.

Item 8. Financial Statements and Supplementary Data

Our consolidated financial statements are listed in the Index to Consolidated Financial Statements filed in Item 15(a)(i) as part of this Form 10-K.

Item 9. Changes in and Disagreements With Accountants On Accounting and Financial Disclosure

None.

Item 9A. Controls and Procedures

Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, which we refer to as the Exchange Act) as of June 30, 2004. As part of the evaluation we considered the report to our audit committee by our independent auditors, Deloitte & Touche, LLP, of a "material weakness" and a "reportable condition" under standards established by the American Institute of Certified Public Accountants regarding certain elements of our system of internal controls. Our independent auditors noted a material weakness with respect to our accounting for income taxes, due to errors in the computations of the provision for sales taxes, the domestic and foreign provision for income taxes, and the computation and classification of deferred income taxes. They also cited a reportable condition with respect to our property record-keeping processes that did not constitute a material weakness.

In designing and evaluating our disclosure controls and procedures, our management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and our management necessarily applied its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on this evaluation, our chief executive officer and chief financial officer concluded that, as of June 30, 2004, as a result of the material weakness in our internal controls over financial reporting described in our auditors report, our disclosure controls and procedures were not effective with respect to our accounting for income taxes and required implementation of the changes discussed below. We have evaluated the impact of the internal control weakness and reportable condition discussed above. Based on our evaluation, we do not believe that the control weakness and reportable condition noted above led to any material misstatements in the consolidated financial statements included in this report.

The following initiatives are being taken to address the material weakness and reportable condition described above and were based on the recommendations of our independent auditors in their letter to our audit committee:

•: hiring of a new tax director;
•: creation of an internal audit department and hiring of a director of internal audit; and
•: purchase and implementation of a fixed asset accounting and tracking system, along with completion of a full physical inventory of all property and equipment.

While we are in the process of taking the foregoing steps, and, in addition, are developing and implementing a formal set of internal controls and procedures for financial reporting in accordance with the SEC's proposed rules to adopt the internal control report requirements included in Section 404 of the Sarbanes-Oxley Act of 2002, in order to address the adequacy of our disclosure controls and procedures, the efficacy of the steps we have taken to date and the steps we are still in the process of completing is subject to continued management review supported by confirmation and testing by management and by our internal and external auditors. As a result, additional changes will be made to our internal controls and procedures.

Other than the foregoing initiatives, no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during the fiscal quarter ended June 30, 2004 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Aspen Technology, Inc.:
Cambridge, Massachusetts

We have audited the accompanying consolidated balance sheets of Aspen Technology, Inc. and subsidiaries (the "Company") as of June 30, 2003 and 2004, and the related consolidated statements of operations, stockholders' equity and comprehensive income (loss), and cash flows for each of the three years in the period ended June 30, 2004. Our audits also included the financial statement schedule listed in the Index at Item 15(a)(2). These financial statements and the financial statement schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements and the financial statement schedule based on our audits.

We conducted our audits in accordance with standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of the Company as of June 30, 2003 and 2004, and the results of its operations and its cash flows for each of the three years in the period ended June 30, 2004, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects the information set forth therein.

ASPEN TECHNOLOGY, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) Operations

Aspen Technology, Inc. (the Company) and its subsidiaries is a leading supplier of integrated software and services to the process industries, which consist of petroleum, chemicals, pharmaceutical and other industries that provide products from a chemical process. The Company develops two types of software to design, operate, manage and optimize its customers' key business processes- engineering software and manufacturing/supply chain software.

(2) Significant Accounting Policies

(a) Principles of Consolidation

The accompanying consolidated financial statements include the results of operations of the Company and its wholly owned subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation.

(b) Management Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

(c) Cash and Cash Equivalents and Short-Term Investments

Cash and cash equivalents consist of short-term, highly liquid investments with original maturities of three months or less.

Securities purchased to be held for indefinite periods of time, and not intended at the time of purchase to be held until maturity, are classified as available-for-sale securities. Unrealized gains and losses have been accounted for as a component of comprehensive income (loss). Realized investment gains and losses were not material in fiscal 2002, 2003 or 2004.

Cash and cash equivalents as of June 30, 2003 and 2004 were as follows (in thousands):

			June 30, 2003				June 30, 2004
Description		Contracted Maturity	Total Market Value		Total Amortized Cost		Total Market Value		Total Amortized Cost
Cash and cash equivalents:
Cash and cash equivalents		N/A	$	22,412	$	22,412	$	75,498	$	75,498
Money market funds		0-3 months		29,155		29,155		32,179		32,179

	Total cash and cash equivalents		$	51,567	$	51,567	$	107,677	$	107,677

(d) Derivative Instruments and Hedging

The Company follows the provisions of Statement of Financial Accounting Standards (SFAS) No. 133, "Accounting for Derivative Instruments and Hedging Activities." SFAS No. 133, as amended by SFAS No. 138, requires that all derivatives, including foreign currency exchange contracts, be

F-9

recognized on the balance sheet at fair value. Derivatives that are not hedges must be adjusted to fair value through earnings. If a derivative is a hedge, depending on the nature of the hedge, changes in the fair value of the derivative are either offset against the change in fair value of assets, liabilities or firm commitments through earnings or recognized in other comprehensive income until the hedged item is recognized in earnings. The ineffective portion of a derivative's change in fair value is immediately recognized in earnings.

Forward foreign exchange contracts are used primarily by the Company to hedge certain balance sheet exposures resulting from changes in foreign currency exchange rates. Such exposures primarily result from portions of the Company's installment receivables that are denominated in currencies other than the U.S. dollar, primarily the Japanese Yen and the British Pound Sterling. These foreign exchange contracts are entered into to hedge recorded installments receivable made in the normal course of business, and accordingly are not speculative in nature. As part of its overall strategy to manage the level of exposure to the risk of foreign currency exchange rate fluctuations, the Company hedges the majority of its installments receivable denominated in foreign currencies.

In addition, in May 2002, as part of the acquisition of Hyprotech Ltd. and related subsidiaries of AEA Technology plc (collectively, Hyprotech), the Company initiated loans with two foreign subsidiaries. The two loans, denominated in British pounds and Canadian dollars, were intended to be a natural hedge against foreign currency risk associated with installment receivable contracts acquired with Hyprotech that were denominated in a currency other than their functional currency. The loan denominated in British pounds was repaid in December 2003 and the loan denominated in Canadian dollars was repaid in January 2004.

At June 30, 2004, the Company had effectively hedged $19.9 million of installments receivable and accounts receivable denominated in foreign currency. The Company does not hold or transact in financial instruments for purposes other than to hedge foreign currency risk. The gross value of the long-term installments receivable that were denominated in foreign currency was $25.2 million at June 30, 2003 and $21.7 million at June 30, 2004. The installments receivable held as of June 2004 mature at various times through November 2009. There have been no material gains or losses recorded relating to hedge contracts for the periods presented.

The Company records its foreign currency exchange contracts at fair value in its consolidated balance sheet and the related gains or losses on these hedge contracts are recognized in earnings. Gains and losses resulting from the impact of currency exchange rate movements on forward foreign exchange contracts are designated to offset certain accounts and installments receivable and are recognized as other income or expense in the period in which the exchange rates change and offset the foreign currency losses and gains on the underlying exposures being hedged. During fiscal 2002, 2003 and 2004 the net gain recognized in the consolidated statements of operations was not material. A small portion of the forward foreign currency exchange contract is designated to hedge the future interest income of the related receivables. The ineffective portion of a derivative's change in fair value is recognized currently through earnings regardless of whether the instrument is designated as a hedge. The gains and losses resulting from the impact of currency rate movements on forward currency exchange contracts are recognized in other comprehensive income for this portion of the hedge. During fiscal 2004, net loss deferred in other comprehensive income was not material.

The following table provides information about the Company's foreign currency derivative financial instruments outstanding as of June 30, 2004. The information is provided in U.S. dollar amounts, as

F-10

presented in the Company's consolidated financial statements. The table presents the notional amount (at contract exchange rates) and the weighted average contractual foreign currency rates:

Currency		Notional Amount		Estimated Fair Value*		Average Contract Rate
		(In thousands)
Euro		$	10,431	$	10,700	0.84
Japanese Yen			5,697		5,644	108.05
Canadian Dollar			2,649		2,721	1.37
British Pound Sterling			1,129		1,205	0.59

	Total	$	19,906	$	20,270

Payments on the hedged receivables due during fiscal 2005 equal $19.8 million.

*: The estimated fair value is based on the estimated amount at which the contracts could be settled based on the spot rates as of June 30, 2004. The market risk associated with these instruments resulting from currency exchange rate movements is expected to offset the market risk of the underlying installments being hedged. The credit risk is that the Company's banking counterparties may be unable to meet the terms of the agreements. The Company minimizes such risk by limiting its counterparties to major financial institutions. In addition, the potential risk of loss with any one party resulting from this type of credit risk is monitored. Management does not expect any loss as a result of default by other parties. However, there can be no assurances that the Company will be able to mitigate market and credit risks described above.

(e) Depreciation and Amortization

The Company provides for depreciation and amortization, primarily computed using the straight-line method, by charges to operations in amounts estimated to allocate the cost of the assets over their estimated useful lives, as follows:

Asset Classification		Estimated Useful Life
Building and improvements		7-30 years
Computer equipment		3 years
Purchased software		3-5 years
Furniture and fixtures		3-10 years
Leasehold improvements		Life of lease or asset, whichever is shorter

Depreciation expense was $15.1 million, $16.4 million and $13.1 million for the years ended June 30, 2002, 2003 and 2004, respectively. During the year ended June 30, 2004, the Company began the process of conducting a physical inventory of all its property and leasehold improvements. During the inventory process, a number of fully depreciated assets were identified as no longer being in service. As a result, the Company removed from the property and leasehold improvement accounts cost and accumulated depreciation of approximately $52.0 million. Since the assets had been fully depreciated, there was no material impact on the statement of operations.

F-11

(f) Revenue Recognition

The Company recognizes revenue in accordance with Statement of Position (SOP) No. 97-2, "Software Revenue Recognition," as amended and interpreted. License revenue, including license renewals, consists principally of revenue earned under fixed-term and perpetual software license agreements and is generally recognized upon shipment of the software if collection of the resulting receivable is probable, the fee is fixed or determinable, and vendor-specific objective evidence (VSOE) of fair value exists for all undelivered elements. The Company determines VSOE based upon the price charged when the same element is sold separately. Maintenance and support VSOE represents a consistent percentage of the license fees charged to customers. Consulting services VSOE represents standard rates that the Company charges its customers when the Company sells its consulting services separately. For an element not yet being sold separately, VSOE represents the price established by management having the relevant authority when it is probable that the price, once established, will not change before the separate introduction of the element into the marketplace. Revenue under license arrangements, which may include several different software products and services sold together, are allocated to each element based on the residual method in accordance with SOP 98-9, "Modification of SOP 97-2, Software Revenue Recognition, with Respect to Certain Transactions." Under the residual method, the fair value of the undelivered elements is deferred and subsequently recognized when earned. The Company has established sufficient VSOE for professional services, training and maintenance and support services. Accordingly, software license revenues are recognized under the residual method in arrangements in which software is licensed with professional services, training and maintenance and support services. The Company uses installment contracts as a standard business practice and has a history of successfully collecting under the original payment terms without making concessions on payments, products or services.

Maintenance and support services are recognized ratably over the life of the maintenance and support contract period. Maintenance and support services include telephone support and unspecified rights to product upgrades and enhancements. These services are typically sold for a one-year term and are sold either as part of a multiple element arrangement with software licenses or are sold independently at time of renewal. The Company does not provide specified upgrades to its customers in connection with the licensing of its software products.

Service revenues from fixed-price contracts are recognized using the proportional performance method, measured by the percentage of costs (primarily labor) incurred to date as compared to the estimated total costs (primarily labor) for each contract. When a loss is anticipated on a contract, the full amount thereof is provided currently. Service revenues from time and expense contracts and consulting and training revenue are recognized as the related services are performed. Services that have been performed but for which billings have not been made are recorded as unbilled services, and billings that have been recorded before the services have been performed are recorded as unearned revenue in the accompanying consolidated balance sheets. In accordance with the Emerging Issues Task Force (EITF) Issue No. 01-14, "Income Statement Characterization of Reimbursements Received for "Out-of-Pocket' Expenses Incurred," reimbursement received for out-of-pocket expenses is recorded as revenue and not as a reduction of expenses.

F-12

(g) Computer Software Development Costs

Certain computer software development costs are capitalized in the accompanying consolidated balance sheets. Capitalization of computer software development costs begins upon the establishment of technological feasibility. In accordance with SFAS No. 86, "Accounting for the Costs of Computer Software to be Sold, Leased, or otherwise Marketed", the Company defines the establishment of technological feasibility as the completion of a detail program design. Amortization of capitalized computer software development costs is provided on a product-by-product basis using the straight-line method, beginning upon commercial release of the product, and continuing over the remaining estimated economic life of the product, not to exceed three years. Total amortization expense charged to operations was approximately $4.6 million, $5.1 million and $6.5 million in fiscal 2002, 2003 and 2004, respectively. During the years ended June 30, 2003 and 2004, the Company recorded impairment charges associated with the capitalized computer software development costs of certain products, totaling $2.9 million and $3.3 million, respectively (see Note 2(m)).

(h) Foreign Currency Translation

The financial statements of the Company's foreign subsidiaries are translated in accordance with SFAS No. 52, "Foreign Currency Translation". The determination of functional currency is based on the subsidiaries' relative financial and operational independence from the Company. Foreign currency exchange gains or losses for certain wholly owned subsidiaries are credited or charged to the accompanying consolidated statements of operations since the functional currency of the subsidiaries is the U.S. dollar. Foreign currency transaction gains or losses are credited or charged to the accompanying consolidated statements of operations as incurred. Gains and losses from foreign currency translation related to entities whose functional currency is their local currency are credited or charged to the accumulated other comprehensive income (loss) account, included in stockholders' equity in the accompanying consolidated balance sheets.

(i) Net Income (Loss) per Share

Basic earnings per share was determined by dividing net income (loss) attributable to common shareholders by the weighted average common shares outstanding during the period. Diluted earnings per share was determined by dividing net income (loss) attributable to common shareholders by diluted weighted average shares outstanding. Diluted weighted average shares reflects the dilutive effect, if any, of potential common shares. To the extent their effect is dilutive, potential common shares include common stock options and warrants, based on the treasury stock method, convertible debentures and preferred stock, based on the if-converted method, and other commitments to be settled in common stock. The calculations of basic and diluted net income (loss) per share attributable to common

F-13

shareholders and basic and diluted weighted average shares outstanding are as follows (in thousands, except per share data):

	Years Ended June 30,
	2002			2003			2004
Net income (loss) attributable to common shareholders	$	(83,466	)	$	(170,017	)	$	(35,048	)

Weighted average potential common shares		—			—			—

Diluted weighted average shares outstanding		32,308			38,476			40,575

Basic net income (loss) per share attributable to common shareholders	$	(2.58	)	$	(4.42	)	$	(0.86	)

Diluted net income (loss) per share attributable to common shareholders	$	(2.58	)	$	(4.42	)	$	(0.86	)

The following potential common shares were excluded from the calculation of dilutive weighted average shares outstanding as their effect would be anti-dilutive (in thousands):

		Years Ended June 30,
		2002	2003	2004
Convertible preferred stock		3,135	3,135	36,336
Options and warrants		11,000	9,965	21,457
Convertible debt		1,628	1,628	1,071

Preferred stock dividend, to be settled in common stock		116	121	1,197

	Total	17,428	16,008	60,061

(j) Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk are principally cash and cash equivalents, short-term investments, accounts receivable and installments receivable. The Company places its cash and cash equivalents and investments in highly rated institutions. Concentration of credit risk with respect to receivables is limited to certain customers (end users and distributors) to which the Company makes substantial sales. To reduce risk, the Company routinely assesses the financial strength of its customers, hedges specific foreign installments receivable and routinely sells its installments receivable to financial institutions with limited recourse and without recourse. As a result, the Company believes that the accounts and installments receivable credit risk exposure is limited. As of June 30, 2003 and 2004, the Company had no customers that represented 10% of total accounts and installments receivable.

(k) Allowance for Doubtful Accounts

The Company makes judgments as to its ability to collect outstanding receivables and provide allowances for the portion of receivables when it is probable that a loss has been incurred. Provisions

F-14

are made based upon a specific review of all significant outstanding invoices and an analysis of historical write-off rates. In determining these provisions, the Company analyzes its historical collection experience and current economic trends.

(l) Financial Instruments

Financial instruments consist of cash and cash equivalents, short-term investments, accounts receivable, installments receivable, foreign exchange contracts and the Company's 5¹/4% convertible subordinated debentures due June 15, 2005 (the Debentures). The estimated fair value of these financial instruments approximates their carrying value and, except for accounts receivable and installments receivable, is based primarily on market quotes.

(m) Intangible Assets, Goodwill and Impairment of Long-Lived Assets

Intangible assets subject to amortization consist of the following at June 30, 2003 and 2004 (in thousands):

		June 30, 2003				June 30, 2004
Asset Class	Estimated Useful Life	Gross Carrying Amount		Accumulated Amortization		Gross Carrying Amount		Accumulated Amortization
Acquired technology	3-5 years	$	44,352	$	17,980	$	44,737	$	25,434
Uncompleted contracts	4 years		1,936		1,619		2,005		1,888
Trade name	10 years		766		569		758		644
Other	3-12 years		246		186		232		195

		$	47,300	$	20,354	$	47,732	$	28,161

Aggregate amortization expense for intangible assets subject to amortization was $5.3 million, $7.4 million and $7.6 million for the years ended June 30, 2002, 2003 and 2004, respectively, and is expected to be $7.4 million, $7.2 million and $5.0 million in each of the next three fiscal years, respectively.

F-15

The changes in the carrying amount of the goodwill by reporting unit for the years ended June 30, 2003 and 2004 were as follows (in thousands):

		Reporting Unit
Asset Class		License			Consulting Services			Maintenance and Training		Total
Carrying amount as of June 30, 2002		$	67,913		$	5,296		$	11,049	$	84,258
	Purchase price adjustment—Hyprotech acquisition		1,407			88			264		1,759

	Effect of exchange rates used for translation		3			8			73		84

Carrying amount as of June 30, 2003			2,358			147			11,828		14,333
	Goodwill acquired during fiscal 2004		—			366			—		366
	Effect of exchange rates used for translation		6			—			31		37

Carrying amount as of June 30, 2004		$	2,364		$	513		$	11,859	$	14,736

In October 2002, management determined that goodwill should be tested for impairment as a result of the following factors:

•: The Company experienced a significant decline in demand for products in its manufacturing/supply-chain product line beginning at the end of the quarter ended September 30, 2002 and continuing through the end of the quarter ended December 31, 2002. While these products had been underperforming for several quarters, the lack of demand during this quarter was significant. Discussions with potential customers revealed that investment in this area would not be forthcoming in the near future and purchases would continue to be delayed indefinitely. As a result, management reduced revenue projections for several of these products. The underperforming manufacturing/supply-chain products included Aspen Metals, PetroVantage, Aspen Bulk, Aspen Buy & Sell, AEP and MIMI.
•: There was a significant decline in the fair market value of the Company's common stock and thus its market capitalization. The Company's market capitalization was approximately $260 million on July 1, 2002. By December 31, 2002, the market capitalization had decreased to a low of approximately $108 million. In addition, during this six month period the Company's market capitalization reached a low of approximately $22 million on October 11, 2002.

An independent third party valued the Company's three reporting units: license, consulting services, and maintenance and training. The valuation was based on an income approach, using a five-year present value calculation of income, and a market approach, using comparable company valuations. Based on this analysis, it was determined that the full values of the goodwill associated with the license reporting unit and consulting services reporting unit were impaired. This resulted in a $74.7 million aggregate impairment charge included on the accompanying consolidated statement of operations as long-lived asset impairment charges. It was also determined that the fair value of the maintenance and training reporting unit exceeded its carrying value, resulting in no impairment of its goodwill. At December 31, 2003, the Company conducted its annual impairment test and determined that goodwill was not impaired. The Company's next annual impairment test will occur on December 31, 2004.

F-16

The Company evaluates it long-lived assets, which include property and leasehold improvements, intangible assets and capitalized software development costs for impairment as events and circumstances indicate that the carrying amount may not be recoverable and at a minimum at each balance sheet date. The Company evaluates the realizability of its long-lived assets based on profitability and undiscounted cash flow expectations for the related asset or subsidiary.

Fiscal 2004—During the fourth quarter of fiscal 2004, the Company completed a comprehensive review of its product offerings, in an effort to reduce duplicative efforts and cut costs. As a result, management decided to discontinue development of certain products, which resulted in an impairment of technology related intangible and computer software development assets of $3.3 million, related to the impairment of certain computer software development costs. These products were considered part of the next-generation manufacturing/supply chain products. Management's decision was based on concerns about the future revenue projections for these products, and the assessment of costs remaining to bring these products to market.

During the fourth quarter of fiscal 2004, the Company recorded long-lived asset impairment charges of $1.0 million. This was partially due to management's decision, as part of the Company's June 2004 cost-cutting initiatives that resulted in the June 2004 restructuring plan, to discontinue certain internal capital projects that had previously been put on hold. In addition, certain fixed assets that supported research and development efforts were considered impaired as a result of the consolidation decisions made in the fourth quarter product offering review.

Fiscal 2003—Concurrent with the restructuring plan and goodwill impairment test that was initiated in October 2002, as discussed previously, the Company cancelled certain internal capital projects and discontinued development and support for certain non-critical products, resulting in the evaluation of the realizibility of long-lived assets and the recording of an impairment charge related to various long-lived assets. The Company recorded an impairment of technology related intangible and computer software development assets of $8.7 million, and long-lived asset impairment charges of $31.4 million. The impairment of technology related intangible and computer software development assets consisted of computer software development costs and intangible assets that were considered to be impaired because they will either no longer be used or their carrying values were in excess of their fair values. The assets that will no longer be used were identified by management's decisions to discontinue future development efforts associated with certain products. The carrying values of the remaining assets were compared to the fair values of those assets resulting in an impairment. The fair values were determined by forecasting the future net cash flows associated with the products.

The long-lived asset impairment charges primarily consisted of a $23.6 million charge related to the intellectual property purchased from Accenture in February 2002. The fair value of this asset was determined by forecasting the future net cash flows associated with the asset and then was compared to its carrying value. This intellectual property is used primarily in the development of manufacturing/supply chain software products, within the license line of business. The revenue expectations for the manufacturing/supply chain product line were significantly reduced by management, which prompted the review for impairment. The remaining $7.8 million charge consisted of fixed assets and internal capital projects that were considered to be impaired because they will either no longer be used or their carrying values were in excess of their fair values. The assets that will no longer be used were identified by management's decisions to discontinue future development efforts associated with certain products. The carrying values of the remaining assets were compared to the fair values of those assets resulting

F-17

in an impairment. The fair values were determined by forecasting the future net cash flows associated with the products.

Fiscal 2002—In June 2002, with the intent of lowering operating costs, the Company made a decision to standardize with a single provider for certain software products that are sold along with the Company's products. This decision resulted in the impairment of $1.2 million of prepaid royalty fees, which was recorded in the accompanying consolidated statement of operations as impairment of technology related intangible and computer software development assets.

(n) Comprehensive Income (Loss)

Comprehensive income (loss) is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. Comprehensive income (loss) is disclosed in the accompanying consolidated statements of stockholders' equity and comprehensive income (loss). The components of accumulated other comprehensive income (loss) as of June 30, 2003 and 2004 are made up of cumulative translation adjustments.

(o) Fair Value of Stock Options

The Company issues stock options to its employees and outside directors and provides employees the right to purchase stock pursuant to stockholder approved stock option and employee stock purchase plans, which are described more fully in Note 8. The Company accounts for these plans under the recognition and measurement principles of Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees", and has elected the disclosure-only alternative under SFAS No. 123 "Accounting for Stock-Based Compensation," as amended by SFAS No. 148. No material stock-based employee compensation cost is reflected in net income (loss), as all options granted under those plans had an exercise price equal to the market value of the underlying common stock on the date of grant.

For pro forma disclosures, the estimated fair value of the options is amortized over the vesting period, typically four years, and the estimated fair value of the stock purchases is amortized over the six-month purchase period. The following table illustrates the effect on net income and earnings per

F-18

share if the Company had applied the fair value recognition provisions of FASB Statement No. 123 to stock-based employee compensation (in thousands, except per share data):

			2002			2003			2004

The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model with the following assumptions used for grants during the applicable period:

	2002			2003			2004
Risk free interest rates		3.91-4.39	%		2.78-4.15	%		3.27-3.50	%

Expected volatility		72	%		125	%		99	%
Weighted average fair value per option	$	8.00		$	2.63		$	2.51

(p) Income Taxes

Deferred income taxes are recognized based on temporary differences between the financial statement and tax bases of assets and liabilities. Deferred tax assets and liabilities are measured using the statutory tax rates and laws expected to apply to taxable income in the years in which the temporary differences are expected to reverse. Valuation allowances are provided against net deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income and the timing of the temporary differences becoming deductible. Management considers, among other available information, scheduled reversals of deferred tax liabilities, projected future taxable income, limitations of availability of net operating loss carryforwards, and other matters in making this assessment.

Income taxes are provided on undistributed earnings of foreign subsidiaries where such earnings are expected to be remitted to the U.S. parent company. The Company determines annually the amount of unremitted earnings of foreign subsidiaries to invest indefinitely in its non-U.S. operations. Unrecognized provisions for taxes on undistributed earnings of foreign subsidiaries, which are considered permanently invested, are not material to the Company's consolidated financial position or results of operations.

F-19

(q) Legal Fees

The Company accrues estimated future legal fees associated with outstanding litigation for which management has determined that it is probable that a loss contingency exists. Liabilities for loss contingencies arising from claims, assessments, litigation and other sources are recorded when it is probable that a liability has been incurred and the amount of the claim assessment or damages can be reasonably estimated.

(r) Advertising costs

The Company charges advertising costs to expense as the costs are incurred. In some cases, in accordance with Accounting Principles Board (APB) Opinion No. 28, "Interim Financial Reporting," the advertising costs are amortized over several interim periods within a fiscal year, if the benefits to the expenditure extend beyond the period in which the costs are incurred. The Company recorded advertising expenses of $11.9 million, $14.1 million and $4.0 million during the years ended June 30, 2002, 2003 and 2004, respectively. As of June 30, 2003 and 2004, the Company had $0.3 million and $0.8 million in prepaid advertising on the accompanying consolidated balance sheets.

(s) Recently Issued Accounting Pronouncements

In April 2003, the FASB issued SFAS No. 149, "Amendment of Statement 133 on Derivative Instruments and Hedging Activities." This pronouncement amends and clarifies financial accounting and reporting for derivative instruments, including certain derivative instruments embedded in other contracts (collectively referred to as derivatives) and for hedging activities under SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities." The provisions of this statement are effective for transactions that are entered into or modified after June 30, 2003. The adoption of SFAS No. 149 did not have a material effect on the Company's consolidated financial position or results of operations.

In January 2003, the FASB issued Interpretation No. 46 (FIN 46), "Consolidation of Variable Interest Entities," which clarifies the application of Accounting Research Bulletin No. 51, "Consolidated Financial Statements," relating to consolidation of certain entities. In December 2003, the FASB revised FIN 46. As revised, FIN 46 will require identification of the Company's participation in variable interest entities (VIE), which are defined as entities with a level of invested equity that is not sufficient to fund future activities to permit them to operate on a stand alone basis, or whose equity holders lack certain characteristics of a controlling financial interest. For entities identified as VIE, FIN 46 sets forth a model to evaluate potential consolidation based on an assessment of which party to the VIE, if any, bears a majority of the exposure to its expected losses, or stands to gain from a majority of its expected returns. FIN 46 also sets forth certain disclosure regarding interests in VIE that are deemed significant, even if consolidation is not required. Certain provisions of FIN 46, as revised, relating to the consolidation of special-purpose entities are effective for periods ending after December 15, 2003. The adoption of these provisions did not have an impact on the Company's financial position, results of operations or cash flows. The remaining provisions of FIN 46, as revised, relating to the consolidation or disclosure of all other VIE are effective for periods ending after March 15, 2004. The adoption of these provisions did not have an impact on the Company's financial position, results of operations or cash flows.

F-20

(t) Reclassifications

Certain amounts in the Company's consolidated balance sheets and consolidated statements of operations and cash flows have been reclassified to conform to the current presentation.

•: Amortization expenses from technology related intangible assets totaling $5.0 million and $8.2 million in the years ended June 30, 2002 and 2003, respectively, have been reclassified from general and administrative expenses to cost of revenues.
•: Charges related to the impairment of technology related intangible assets and computer software development assets totaling $1.2 million and $8.7 million in the years ended June 30, 2002 and 2003, respectively, have been reclassified from restructuring charges and FTC legal costs to cost of revenues.
•: Asset impairment charges totaling $31.4 million in the year ended June 30, 2003 have been reclassified from restructuring charges and FTC legal costs to long-lived asset impairment charges.

(3) Restructuring and Other Charges

(a) Fiscal 2004

During fiscal 2004, the Company recorded $20.8 million in restructuring charges and FTC legal costs. Of this amount, $23.8 million is associated with a June 2004 restructuring plan, which is offset by $7.9 million in adjustments to prior restructuring accruals and deferred rent balances, and $4.9 million is FTC legal costs.

In June 2004, the Company initiated a plan to reduce its operating expenses in order to better align its operating cost structure with the current economic environment and to improve its operating margins. This plan coincided with a reduction in management's revenue projections for fiscal 2005. The plan to reduce operating expenses resulted in the consolidation of facilities, headcount reductions, and the termination of operating lease contracts. These actions resulted in an aggregate restructuring charge of $23.8 million. The $7.9 million in adjustments to the prior restructuring accruals and deferred rent balances is primarily related to the buy-out of the Company's remaining lease obligation for its Houston facility, of which portions had previously been vacated by the Company and included in previous restructuring plans. The components of the restructuring plan are as follows (in thousands):

		Closure/ Consolidation of Facilities and Contract exit costs			Employee Severance, Benefits, and Related Costs			Impairment of Assets			Total
Restructuring charge		$	20,984		$	1,046		$	1,776		$	23,806
	Fiscal 2004 payments		(8,435	)		(280	)		—			(8,715	)
	Impairment of assets		—			—			(1,776	)		(1,776	)

Accrued expenses, June 30, 2004		$	12,549		$	766		$	—		$	13,315

Expected final payment date			February 2007			December 2004

F-21

Employee severance, benefits and related costs: Approximately $1.0 million of the restructuring charge relates to the reduction in headcount. Approximately 35 employees, or 2% of the workforce, were eliminated under the restructuring plan implemented by management. A majority of the employees were located in North America, although Europe was affected, as well. All business units were affected, including services, sales and marketing, research and development, and general and administrative.

Impairment of assets: Approximately $1.8 million of the restructuring charge relates to charges associated with the impairment of fixed assets associated with the closed and consolidated facilities. These assets were reviewed for impairment in accordance with SFAS No. 144, and were considered to be impaired because their carrying values were in excess of their fair values. The fair values were determined based on a quoted market price from a third party.

(b) Fiscal 2003

During fiscal 2003, the Company recorded $41.1 million in restructuring charges and FTC legal costs. Of this amount, $28.1 million is associated with an October 2002 restructuring plan, and $13.0 million is FTC legal costs, related to the FTC challenge of the Company's acquisition of Hyprotech.

In October 2002, management initiated a plan to further reduce operating expenses in response to first quarter revenue results that were below expectations and general economic uncertainties. In addition, management revised revenue expectations for the remainder of the fiscal year and beyond, primarily related to the manufacturing/supply chain product line, which has been affected the most by the current economic conditions. The plan to reduce operating expenses resulted in headcount reductions, consolidation of facilities, and discontinuation of development and support for certain non-critical products. These actions resulted in an aggregate restructuring charge of $16.1 million, recorded during the three months ended December 31, 2002. In June 2003, the Company reviewed its estimates to this plan and recorded a $12.0 million increase to the accrual, primarily due to revisions of

F-22

the facility sub-lease assumptions, as well as increases to severance and other costs. The components of the restructuring plan are as follows (in thousands):

		Closure/ Consolidation of Facilities			Employee Severance, Benefits, and Related Costs			Impairment of Assets and Disposition Costs			Total
Restructuring charge		$	17,347		$	10,028		$	714		$	28,089
	Net recovery/impairment of assets		—			—			866			866
	Fiscal 2003 payments		(3,548	)		(7,297	)		—			(10,845	)

Accrued expenses, June 30, 2003			13,799			2,731			1,580			18,110
	Fiscal 2004 payments		(2,567	)		(2,170	)		(770	)		(5,507	)
	Adjustment—Facility lease buyout		(4,122	)		—			—			(4,122	)
	Adjustment—Revised assumptions		(385	)		(269	)		(134	)		(788	)

Accrued expenses, June 30, 2004		$	6,725		$	292		$	676		$	7,693

Expected final payment date			December 2010			April 2005			April 2005

Closure/consolidation of facilities: Approximately $17.4 million of the restructuring charge relates to the termination of facility leases and other lease related costs. Of this amount, approximately $8.7 million was recorded in the three months ended December 31, 2002 and approximately $8.7 million was recorded as a result of the June 2003 increase to the accrual. The facility leases had remaining terms ranging from several months to eight years. The amount accrued is an estimate of the remaining obligation under the lease or actual costs to buy-out leases, reduced by expected income from the sublease of the underlying properties. The June 2003 increase to the accrual is primarily due to revised estimates related to sublease assumptions, as actual sublease rates have been significantly less than originally estimated and the Company has experienced delays contracting with sub-lessors. In June 2004, the remaining accrual associated with one of the leased facilities was paid, as the Company executed a buy-out of the remaining facility lease obligation as part of the June 2004 restructuring plan. The adjustments to the accrual that occurred in fiscal 2004 relate to revisions made to sublease assumptions.

Employee severance, benefits and related costs: Approximately $10.0 million of the restructuring charge relates to the reduction in headcount. Of this amount, approximately $8.2 million was recorded in the three months ended December 31, 2002 and approximately $1.8 million was recorded as a result of the June 2003 increase to the accrual. Approximately 400 employees, or 20% of the workforce, were eliminated under the restructuring plan implemented by management. All geographic regions and business units were affected, including services, sales and marketing, research and development, and general and administrative. The adjustments to the accrual that occurred in fiscal 2004 relate to revisions of estimates of severance terms and benefit levels.

Impairment of assets and disposition costs: Approximately $0.7 million of the restructuring charge relates to charges associated disposing of certain products and assets. This consisted of costs related to preparing certain development groups for divestment or closure, offset by a gain related to the cancellation of a note payable to a European government. The note payable was related to the research and development group that was divested as part of the restructuring plan. The adjustments to the

F-23

accrual that occurred in fiscal 2004 relate to revisions of estimates of ongoing costs of disposal activities.

(c) Fiscal 2002

In the third quarter of fiscal 2002, revenues were lower than expectations as customers delayed spending due to the general weakness in the economy. The Company reduced revenue expectations for the fourth quarter and for the fiscal year 2003. Based upon the impact of these reduced revenue expectations, management evaluated the Company's current business and made significant changes, resulting in a restructuring plan for its operations. This restructuring plan included a reduction in headcount, tighter cost controls, and the close-down and consolidation of facilities. The restructuring charge is broken down as follows (in thousands):

		Closure/ Consolidation of Facilities			Employee Severance, Benefits, and Related Costs			Total
Restructuring charge		$	4,901		$	8,285		$	13,186
	Fiscal 2002 payments		—			(1,849	)		(1,849	)

Accrued expenses, June 30, 2002			4,901			6,436			11,337
	Fiscal 2003 payments		(695	)		(4,748	)		(5,443	)

Accrued expenses, June 30, 2003			4,206			1,688			5,894
	Fiscal 2004 payments		(1,302	)		(1,060	)		(2,362	)
	Adjustment—Facility lease buyout		(727	)		—			(727	)

Accrued expenses, June 30, 2004		$	1,827		$	130		$	1,957

Expected final payment date			December 2010			April 2005

Closure/consolidation of facilities: Approximately $4.9 million of the restructuring charge relates to the termination of facility leases and other lease-related costs. The facility leases had remaining terms ranging from several months to nine years. The amount accrued is an estimate of the actual costs to buy-out leases or to sublease the underlying properties. In June 2004, the remaining accrual associated with one of the leased facilities was paid, as the Company executed a buy-out of the remaining facility lease obligation as part of the June 2004 restructuring plan. The adjustments to the accrual that occurred in fiscal 2004 relate to revisions made to sublease assumptions, as actual sublease rates have been significantly less than originally estimated and the Company has experienced delays contracting with sub-lessors.

Employee severance, benefits and related costs: Approximately $8.3 million of the restructuring charge relates to the reduction in headcount. Approximately 200 employees, or 10% of the workforce, were eliminated under the changes to the business plan implemented by management. Business units impacted included sales and marketing, services, research and development, and general and administrative, across all geographic areas. The adjustments to the accrual that occurred in fiscal 2004 relate to revisions of estimates of severance terms and benefit levels.

F-24

Write-off of assets: Approximately $1.2 million of the restructuring charge relates to the write-off of prepaid royalties related to third-party software products that the Company will no longer support and sell.

(d) Fiscal 2001

In the third quarter of fiscal 2001 the revenues realized by the Company were reduced from the Company's expectations as customers delayed spending in the widespread slowdown in information technology spending and the deferral of late-quarter purchasing decisions. The Company reduced its revenue expectations for the fourth quarter and for the fiscal year 2002 until revenue visibility and predictability improved. Based on these reduced revenue expectations Company management evaluated the business plan and made significant changes, resulting in a restructuring plan for the Company's operations. This restructuring plan included a reduction in headcount, a substantial decrease in discretionary spending and a sharpening of the Company's e-business focus to emphasize its marketplace solutions, and resulted in a pre-tax restructuring charge totaling $7.0 million. The restructuring charge is broken down as follows (in thousands):

		Closure/ Consolidation of Facilities			Employee Severance, Benefits, and Related Costs			Write-off of Assets			Total
Restructuring charge		$	2,774		$	3,148		$	1,047		$	6,969
	Write-off of asset		—			—			(1,047	)		(1,047	)

	Adjustment—Facility lease buyout		(328	)		—			—			(328	)

Accrued expenses, June 30, 2004		$	—		$	—		$	—		$	—

Closure/consolidation of facilities: Approximately $2.8 million of the restructuring charge relates to the termination of facility leases and other lease-related costs. The facility leases had remaining terms ranging from one month to six years. The amount accrued reflects the Company's best estimate of the actual costs to buy out the leases in certain cases of the net cost to sublease the properties in other cases. Included in this amount is the write-off of certain assets, primarily leasehold improvements. The adjustments to the accrual that occurred in fiscal 2002 relate to revisions made to sublease assumptions, as actual sub-lease rates have been significantly less than originally estimated and the Company has experienced delays contracting with sub-lessors. In June 2004, the remaining accrual was paid, as the Company executed a buy-out of the remaining facility lease obligation as part of the June 2004 restructuring plan.

F-25

Employee severance, benefits and related costs: Approximately $3.2 million of the restructuring charge relates to the reduction in workforce. Approximately 100 employees, or 5% of the workforce, were eliminated under the changes to the business plan implemented by Company management. Areas impacted included sales and marketing, services, general and administrative, and research and development.

Write-off of assets: Approximately $1.0 million of the restructuring and other charges relates to the impairment of an investment in certain e-business initiatives that the Company will no longer support as a direct consequence of the change in business plan.

(e) Fiscal 1999

In the fourth quarter of fiscal 1999, the Company experienced a significant slow down in certain of its businesses due to difficulties that customers in its core vertical markets of refining, chemicals and petrochemicals were experiencing. These markets were experiencing a significant decrease in pricing for their products, which significantly reduced their revenues and related cash inflows. In turn, these companies began to reduce their capital spending and lengthened the evaluation and decision-making cycle for purchases. The impact of this on the Company was dramatic, lowering license revenues from expected levels by a significant amount. Based on these reduced revenues, Company management made significant changes to the business plan, resulting in a restructuring plan. The restructuring plan

F-26

resulted in a pre-tax restructuring charge totaling $17.9 million. The restructuring and other charges are broken down as follows (in thousands):

		Closure/ Consolidation of Facilities			Employee Severance, Benefits, and Related Costs			Write-off of Assets			Other			Total
Restructuring and other charges		$	10,224		$	4,324		$	3,060		$	259		$	17,867

Expected final payment date			December 2004

Closure/consolidation of facilities: Approximately $10.2 million of the restructuring charge relates to the termination of facility leases and other lease-related costs. The facility leases had remaining terms ranging from one month to six years. The amount accrued reflects the Company's best estimate of actual costs to buy out the leases in certain cases or the net cost to sublease the properties in other cases. Included in this amount is the write-off of certain assets, primarily building and leasehold improvements and adjustments to certain obligations that relate to the closing of facilities. The adjustment to the accrual during fiscal 2002 is due to revisions in some of the original sublease assumptions, as actual sub-lease terms have been longer than originally estimated.

Employee severance, benefits and related costs: Approximately $4.3 million of the restructuring charge relates to the reduction in workforce. Approximately 200 employees, or 12% of the workforce, were eliminated as the Company rationalized its product and service offerings against customer needs in various markets.

Write-off of assets: Approximately $3.1 million of the restructuring and other charge relates to the write-off of certain assets that had been determined to be of no further value to the Company as a direct consequence of the change in the business plans that have been made as a result of the restructuring. These business plan changes are the result of management's assessment and

F-27

rationalization of certain non-core products and activities acquired in recent years. The write-off was based on management's assessment of the current fair value of certain assets, including intangible assets, and their resale value, if any.

(4) Acquisitions and Dispositions

The Company recorded a loss on the sale of the net assets of $0.9 million, which was included in the restructuring and other charge as discussed Note 3.

(c) Acquisitions During Fiscal Year 2002

On May 31, 2002, the Company acquired Hyprotech, a market leader in providing software and service solutions designed to improve profitability and operating performance for process industry clients by simulating plant design and operations. The Company acquired 100% of the outstanding capital of Hyprotech for a purchase price of approximately $105.0 million, consisting of $96.6 million in cash and $8.4 million in transaction costs.

In December 2002, the Company made adjustments to the purchase price allocation associated with the acquisition. These consisted of various adjustments to the opening balance sheet to accrue for certain obligations and contingencies and to write-off certain assets. These adjustments resulted in an approximately $1.8 million increase to goodwill.

The following table represents selected unaudited pro forma combined financial information for the Company and Hyprotech, assuming the companies had combined at the beginning of fiscal 2002 (in thousands, except per share data):

Pro forma results are not necessarily indicative of either actual results of operations that would have occurred had the acquisition been made at the beginning of fiscal 2002 or of future results.

On April 30, 2002, the Company acquired 100% of Richardson Engineering Services, Inc. (Richardson) and Skelton & Plummer Project Engineering, PTY Limited (S&P). Richardson is a provider of construction cost estimation software and data, while the group of employees acquired from S&P will expand the scope of sales and service in sub-Saharan Africa.

These acquisitions were accounted for as purchase transactions, and accordingly, the results of operations from the dates of acquisition are included in the Company's consolidated statements of operations commencing as of the acquisition dates. Total purchase price for these acquisitions was approximately $3.2 million, consisting of $3.1 million in cash and $0.1 million in acquisition-related costs.

The purchase prices were allocated to the fair market value of assets acquired and liabilities assumed, as follows (in thousands):

Description		Amount			Life
Goodwill		$	2,111		—
Acquired technology			1,510		5 years

			3,621
Net fair value of tangible assets acquired, less liabilities assumed			(445	)

	Total purchase price	$	3,176

Pro forma information related to these acquisitions is not presented, as the effect of these acquisitions was not material.

(d) Purchase Price Allocation

Allocation of the purchase prices for all acquisitions were based on estimates of the fair value of the net assets acquired. The fair market value of significant intangible assets acquired was based on independent appraisals. In making each of these purchase price allocations, the Company considered present value calculations of income, an analysis of project accomplishments and remaining outstanding items and an assessment of overall contributions, as well as project risks. The values assigned to purchased in-process technology were determined by estimating the costs to develop the acquired technologies into commercially viable products, estimating the resulting net cash flows from the projects, and discounting the net cash flows to their present values. The revenue projections used to value the in-process research and development were based on estimates of relevant market sizes and growth factors, expected trends in technology, and the nature and expected timing of new product introductions by the Company and its competitors. The resulting net cash flows from the projects are based on estimates of cost of sales, operating expenses, and income taxes from the projects. The rates utilized to discount the net cash flows to their present value were based on estimated costs of capital calculations. Due to the nature of the forecasts and the risks associated with the projected growth and profitability of the developmental projects, discount rates of 20 to 40 percent were considered appropriate for the in-process research and development. Risks related to the completion of technology under development include the inherent difficulties and uncertainties in achieving technological feasibility, anticipated levels of market acceptance and penetration, market growth rates and risks related to the impact of potential changes in future target markets.

(5) Line of Credit

In January 2003, the Company executed a Loan Arrangement with Silicon Valley Bank. This arrangement provides a line of credit of up to the lesser of (i) $15.0 million or (ii) 70% of eligible domestic receivables, and a line of credit of up to the lesser of (i) $10.0 million or (ii) 80% of eligible foreign receivables. The lines of credit bear interest at the bank's prime rate (4.00% at June 30, 2004). The Company is required to maintain a $4.0 million compensating cash balance with the bank, or be subject to an unused line fee and collateral handling fees. The lines of credit will initially be collateralized by nearly all of the assets of the Company, and upon achieving certain net income targets, the collateral will be reduced to a lien on the accounts receivable. The Company is required to meet certain financial covenants, including minimum tangible net worth, minimum cash balances and an adjusted quick ratio. The Company capitalized $0.3 million in costs associated with the origination of the Loan Arrangement, which are being amortized to interest expense over the life of the agreement. The Loan Arrangement expires in January 2005.

As of June 30, 2004, there were $11.9 million in letters of credit outstanding under the line of credit, and there was $7.4 million available for future borrowing. As of June 30, 2004, the Company was in default of the tangible net worth covenant. On September 10, 2004, the Company executed an amendment to the Loan Arrangement that adjusted the terms of certain financial covenants, and cured the default as of June 30, 2004. The Loan Arrangement expires in January 2005, and the Company is currently in negotiations with the bank to amend and extend the agreement.

2007		224
2008		183
2009		181
Thereafter		401

	$	60,547

The mortgage payable of the UK subsidiary and the capital lease obligations are collateralized by the property and equipment to which they relate.

In June 1998, the Company sold $86.3 million of the Debentures to qualified institutional buyers. The Debentures are convertible into shares of the Company's common stock at any time prior to June 15, 2005, unless previously redeemed or repurchased, at a conversion price of $52.97 per share, subject to adjustment in certain events. Interest on the Debentures is payable on June 15 and December 15 of each year. The Debentures are redeemable in whole or part at the option of the Company at any time on or after June 15, 2001 at the following redemption prices expressed as a percentage of principal plus accrued interest through the date of redemption:

12 Months Beginning June 15 of	Redemption Price
2001	103.00	%
2002	102.25	%
2003	101.50	%
2004	100.75	%

F-32

In the event of a change of control, as defined, each holder of the Debentures may require the Company to repurchase the Debentures, in whole or in part, for cash or, at the Company's option, for common stock (valued at 95% of the average last reported sale prices for the 5 trading days immediately preceding the repurchase date) at a repurchase price of 100% of the principal amount of the Debentures to be repurchased, plus accrued interest to the repurchase date. The Debentures are unsecured obligations subordinate in right of payment to all existing and future senior debt of the Company, as defined, and effectively subordinate in right of payment to all indebtedness and other liabilities of the Company's subsidiaries. The Company has filed a shelf registration statement in respect of the Debentures and common stock issuable upon conversion thereof.

In connection with the sale and issuance of the Debentures, the Company incurred approximately $3.9 million of issuance costs. These costs have been classified as other assets in the accompanying consolidated balance sheets and are being amortized, as interest expense, over the term of the Debentures. The Company recorded interest expense associated with these debentures of $5.1 million, $5.1 million and $4.5 million in the years ended June 30, 2002, 2003 and 2004, respectively.

During fiscal 2004, the Company used a portion of the proceeds from the Series D-1 and Series D-2 redeemable convertible preferred stock financing to repurchase and retire $29.5 million of the Debentures.

(7) Preferred Stock

The Company's Board of Directors is authorized, subject to any limitations prescribed by law, without further stockholder approval, to issue, from time to time, up to an aggregate of 10,000,000 shares of preferred stock in one or more series. Each such series of preferred stock shall have such number of shares, designations, preferences, voting powers, qualifications and special or relative rights or privileges, which may include, among others, dividend rights, voting rights, redemption and sinking fund provisions, liquidation preferences and conversion rights, as shall be determined by the Board of Directors in a resolution or resolutions providing for the issuance of such series. Any such series of preferred stock, if so determined by the Board of Directors, may have full voting rights with the common stock or limited voting rights and may be convertible into common stock or another security of the Company.

Series B redeemable convertible preferred stock

In February and March 2002, the Company sold 40,000 shares of Series B-I convertible preferred stock (Series B-I Preferred), and 20,000 shares of Series B-II convertible preferred stock (Series B-II Preferred and, collectively with Series B-I Preferred, the Series B Preferred) together with (i) warrants to purchase 507,584 shares of common stock at an initial exercise price of $23.99 per share and (ii) warrants to purchase 283,460 shares of common stock at an initial exercise price of $20.64 per share, to three institutional investors for an aggregate purchase price of $60.0 million. The Company received approximately $56.6 million in net cash proceeds after closing costs.

The Company allocated the net consideration received from the sale of the Series B Preferred between the Series B Preferred and the warrants on the basis of the relative fair values at the date of issuance, allocating $8.0 million to the warrants. The warrants are exercisable at any time prior to the fifth anniversary of their issue date. The fair value of the common shares into which the Series B Preferred was convertible on the date of issuance exceeded the proceeds allocated to the Series B

F-33

Preferred by $3.2 million, resulting in a beneficial conversion feature that was recognized as an increase in additional paid-in-capital and as a discount to the Series B Preferred. This additional discount was immediately accreted through a charge to accumulated deficit in fiscal 2002. The remaining discount on the Series B Preferred was being accreted to its redemption value over the earliest period of redemption.

The Series B Preferred accrued dividends at an annual rate of 4% that were payable quarterly, commencing June 30, 2002, in either cash or common stock, at the Company's option (subject to the satisfaction of specified conditions). During fiscal 2003, the Company issued 731,380 shares of common stock in settlement of its dividend obligations through March 31, 2003. In July 2003, the Company issued 120,740 shares of common stock in settlement of its dividend obligations for the three months ended June 30, 2003.

In June 2003, the Company amended the terms of the Series B Preferred in conjunction with the Series D-1 and Series D-2 redeemable convertible preferred stock financing. This amendment gave the holders of the Series B Preferred the right to redeem their Series B Preferred shares for cash in certain circumstances that were outside of the Company's control. As a result of this redemption feature, the carrying value of the Series B Preferred was reclassified outside of stockholders' equity on the accompanying consolidated balance sheet. In August 2003, the Company repurchased all of the outstanding shares of Series B Preferred.

Series D redeemable convertible preferred stock

In August 2003, the Company issued and sold 300,300 shares of Series D-1 redeemable convertible preferred stock (Series D-1 Preferred), along with warrants to purchase up to 6,006,006 shares of common stock at a price of $3.33 per share, in a private placement to several investment partnerships managed by Advent International Corporation for an aggregate purchase price of $100.0 million. Concurrently, the Company paid cash of $30.0 million and issued 63,064 shares of Series D-2 convertible preferred stock (Series D-2 Preferred), along with warrants to purchase up to 1,261,280 shares of common stock at a price of $3.33 per share, to repurchase all of the outstanding Series B Preferred. In addition, the Company exchanged existing warrants to purchase 791,044 shares of common stock at an exercise price ranging from $20.64 to $23.99 held by the holders of the Series B Preferred, for new warrants to purchase 791,044 shares of common stock at an exercise price of $4.08. These transactions are referred to collectively as the Series D Preferred financing.

The Company incurred $10.7 million in costs related to the issuance of the Series D-1 and D-2 Preferred (together, the Series D Preferred) and allocated the net proceeds received between the Series D Preferred and the warrants on the basis of the relative fair values at the date of issuance, allocating $15.5 million of proceeds to the warrants. The warrants are exercisable at any time prior to the seventh anniversary of their issue date. The remaining discount on the Series D Preferred is being accreted to its redemption value over the earliest period of redemption.

The value of total consideration paid to the holders of the Series B Preferred, consisting of cash, Series D-2 Preferred and warrants, was less than the carrying value of the Series B Preferred at the time of retirement. This resulted in a gain of $6.5 million, which the Company recorded in the accretion of preferred stock discount and dividend line of the accompanying consolidated condensed statement of operations.

F-34

Each share of Series D Preferred is entitled to vote on all matters in which holders of common stock are entitled to vote, receiving a number of votes equal to the number of shares of common stock into which it is then convertible. In addition, holders of Series D-1 Preferred, as a separate class, are entitled to elect a certain number of directors, based on a formula as defined in the series D Preferred Certificate of Designations. The holders of the Series D-1 Preferred are entitled to elect a number of the Company's directors calculated as a ratio of the Series D-1 Preferred voting power as compared to the total voting power of the Company's common stock. The Series D-1 Preferred holders have elected four of the Company's current directors.

The Series D Preferred earns cumulative dividends at an annual rate of 8%, which are payable when and if declared by the Board of Directors, in cash or, subject to certain conditions, common stock. As of June 30, 2004, the Company has accrued $8.7 million in dividends on the Series D Preferred.

Each share of Series D Preferred is convertible at any time into a number of shares of common stock equal to its stated value divided by the then-effective conversion price. The stated value is currently $333.00 per share and is subject to adjustment in the event of any stock dividend, stock split, reverse stock split, recapitalization, or like occurrences. The current conversion price is $3.33 per share. As a result, each share of Series D Preferred currently is convertible into 100 shares of common stock, and in the aggregate, the Series D Preferred currently is convertible into 36,336,400 shares of common stock. The Series D Preferred have anti-dilution rights that will adjust the conversion ratio downwards in the event that the Company issues certain additional securities at a price per share less than the conversion price then in effect.

The Series D Preferred is subject to redemption at the option of the holders as follows: 50% on or after August 14, 2009 and 50% on or after August 14, 2010. The shares will be redeemed for cash at a price of $333.00 per share, plus accumulated but unpaid dividends.

In the accompanying consolidated statements of operations, the accretion of preferred stock discount and dividend consist of the following (in thousands):

(8) Common Stock

(a) Common stock financing

In May 2002, the Company issued and sold 4,166,665 shares of common stock together with warrants to purchase common stock to a group of institutional investors and two individuals, for an aggregate purchase price of $50 million. The net proceeds from this transaction were $48.0 million. The Company issued warrants with five-year lives to purchase up to 750,000 additional shares of common stock at a price of $15.00 per share and also issued a second class of warrants that entitled the investors to purchase, on or prior to July 28, 2002, up to 2,083,333 shares of common stock at a price of $13.20, together with five year warrants to purchase an additional 375,000 shares of common stock at a price of $15.60. The second class of warrants expired unexercised.

(b) Warrants

In connection with the August 1997 acquisition of NeuralWare, Inc., the Company converted warrants to purchase NeuralWare common stock into warrants to purchase 10,980 shares of the Company's common stock. Warrants to purchase 1,260 shares have expired through June 30, 2004. All remaining warrants are currently exercisable with an exercise price of $120.98 per share.

In connection with the February and March 2002 sales of Series B Preferred, the Company issued warrants with five-year lives to purchase 791,044 shares of common stock at an exercise price ranging from $20.64 to $23.99 per share, as noted above in Note 9. In August 2003, in conjunction with the Series D Preferred financing, these warrants were exchanged for new warrants to purchase 791,044 shares of common stock at an exercise price of $4.08 per share. As of June 30, 2004, none of these warrants had been exercised.

In connection with the May 2002 sale of common stock to private investors, the Company issued warrants to purchase up to 3,208,333 shares of common stock, as noted above in Note 10(a). During fiscal 2003 the second class of warrants to purchase up to 2,458,333 shares of common stock expired unexercised. In August 2003, the remaining warrants were canceled, and new warrants were issued to purchase 1,152,665 shares at an exercise price of $9.76 per share, due to the impact of the Series D Preferred financing on the warrants' anti-dilution provisions. In January 2004, warrants to purchase 129,191 shares of common stock were exercised in a cashless exercise, resulting in the issuance of 17,922 shares of common stock. As of June 30, 2004, warrants to purchase 1,023,474 shares of common stock at an exercise price of $9.76 were exercisable.

In connection with the August 2003 Series D Preferred financing, the Company issued warrants with seven-year lives to purchase 7,267,286 shares of common stock at an exercise price of $3.33 per share. As of June 30, 2004, none of these warrants had been exercised.

(c) Stock Options

In December 2000, the shareholders approved the establishment of the 2001 Stock Option Plan (the 2001 Plan), which provides for the issuance of incentive stock options and nonqualified options. Under the 2001 Plan the Board of Directors may grant stock options to purchase up to an aggregate of 4,000,000 shares of common stock. At July 1, 2002, July 1, 2003 and July 1, 2004, the 2001 Plan was expanded to cover an additional 5% of the outstanding shares on the preceding June 30, rounded down to the neared number divisible by 10,000. In no event, however, may the number of shares subject to incentive options under the 2001 Option Plan exceed 8,000,000 unless the 2001 Plan is amended, and

F-36

approved, by the shareholders. As of June 30, 2004, there were 278,470 shares of common stock available for grant under the 2001 Plan. On July 1, 2004, the total number of shares of common stock issuable under the 2001 stock option plan increased by 2,080,000.

In November 1995, the Board of Directors approved the establishment of the 1995 Stock Option Plan (the 1995 Plan) and the 1995 Directors Stock Option Plan (the 1995 Directors Plan), which provided for the issuance of incentive stock options and nonqualified options. Under these plans, the Board of Directors may grant stock options to purchase up to an aggregate of 3,827,687 (as adjusted) shares of common stock. In December 1996, the shareholders of the Company approved the establishment of the 1996 Special Stock Option Plan (the 1996 Plan). This plan provides for the issuance of incentive stock options and nonqualified options to purchase up to 500,000 shares of common stock. The exercise price of options are granted at a price not less than 100% of the fair market value of the common stock on the date of grant. Stock options become exercisable over varying periods and expire no later than 10 years from the date of grant. As of June 30, 2004, there were 459,560 shares of common stock available for grant under the 1995 Plan, 472,579 shares available for grant under the 1995 Directors Plan, and 50,648 shares available for grant under the 1996 Plan.

(d) Employee Stock Purchase Plans

In October 1997, the Company's Board of Directors approved the 1998 Employee Stock Purchase Plan, under which the Board of Directors may grant stock purchase rights for a maximum of 1,000,000 shares through September 30, 2007. In December 2000 and 2003, the shareholders voted to increase the number of shares eligible under the 1998 Employee Stock Purchase Plan by 2,000,000 and 3,000,000 shares, respectively.

Participants are granted options to purchase shares of common stock on the last business day of each semi-annual payment period for 85% of the market price of the common stock on the first or last business day of such payment period, whichever is less. The purchase price for such shares is paid through payroll deductions, and the current maximum allowable payroll deduction is 10% of each eligible employee's compensation. Under the plan, the Company issued 313,337, 759,771 and 976,960 shares during fiscal 2002, 2003 and 2004, respectively. As of June 30, 2004, there were 3,149,530 shares available for future issuance under the 1998 Employee Stock Purchase Plan as amended. In addition, on July 1, 2004, the Company issued 210,241 shares under the 1998 Employee Stock Purchase Plan.

(e) Stockholder Rights Plan

During fiscal 1998, the Board of Directors of the Company adopted a Stockholder Rights Agreement (the Rights Plan) and distributed one Right for each outstanding share of Common Stock. The Rights were issued to holders of record of Common Stock outstanding on March 12, 1998. Each share of Common Stock issued after March 12, 1998 will also include one Right, subject to certain

F-38

limitations. Each Right when it becomes exercisable will initially entitle the registered holder to purchase from the Company one one-hundredth (1/100th) of a share of Series A Preferred Stock at a price of $175.00 (the Purchase Price).

The Rights will become exercisable and separately transferable when the Company learns that any person or group has acquired beneficial ownership of 15% or more of the outstanding Common Stock or on such other date as may be designated by the Board of Directors following the commencement of, or first public disclosure of an intent to commence, a tender or exchange offer for outstanding Common Stock that could result in the offeror becoming the beneficial owner of 15% or more of the outstanding Common Stock. In such circumstances, holders of the Rights will be entitled to purchase, for the Purchase Price, a number of hundredths of a share of Series A Preferred Stock equivalent to the number of shares of Common Stock (or, in certain circumstances, other equity securities) having a market value of twice the Purchase Price. Beneficial holders of 15% or more of the outstanding Common Stock, however, would not be entitled to exercise their Rights in such circumstances. As a result, their voting and equity interests in the Company would be substantially diluted if the Rights were to be exercised.

The Rights expire in March 2008, but may be redeemed earlier by the Company at a price of $.01 per Right, in accordance with the provisions of the Rights Plan.

The Company amended the Rights Plan in June 2003 so that the terms of the Rights Plan would not be applicable to the securities issued as part of the Series D preferred financing or to any securities issued in the future pursuant to the preemptive rights granted as part of this financing.

In fiscal 2001, restricted stock covering 94,500 shares of the Company's common stock was issued. The restricted stock is subject to vesting terms whereby the entire amount will vest upon the earlier of seven years from the date of grant or the attainment of certain performance goals, as defined.

Consideration of $3.00 per share was received for these shares, resulting in deferred compensation of $1.5 million based on the fair market value on the date of issuance of the restricted stock. Of this deferred compensation, $0.1 million and $0.2 million was expensed in fiscal 2001 and fiscal 2002, respectively. The consideration received was in the form of secured promissory notes from the holders of the restricted stock. These notes are subject to interest at an annual rate of 5.07%, are due seven years from the date of issuance and are secured by the restricted stock. The interest under these notes is subject to full recourse against the personal assets of the holders of the restricted stock.

In May 2002, the holders of the restricted stock were terminated from their employment with the Company. At the time of termination, the performance goals had not been attained, and none of the restricted stock had vested. In accordance with the terms of the restricted stock agreements, the Company repurchased the stock at the original purchase price of $3.00 per share. The Company recorded an entry to reverse the $1.2 million of unamortized deferred compensation and $0.3 million of the previously recognized compensation expense associated with the stock.

(9) Income Taxes

The Company accounts for income taxes under the provisions of SFAS No. 109, "Accounting for Income Taxes." Under the liability method specified by SFAS No. 109, a deferred tax asset or liability is

As of June 30, 2004, the Company had net operating loss (NOL) carryforwards for U.S. federal and state income tax purposes of approximately $72 million and $39 million, respectively, and foreign net operating loss carryforwards of approximately $20 million. The Company had federal tax credits and state tax credits of approximately $20 million and $3 million, respectively. The tax credits and NOL carryforwards expire at various dates from 2005 through 2024. The Company has determined that it underwent an ownership change (as defined under section 382 of the Internal Revenue Code of 1986, as amended) during the year ended June 30, 2004. As such, the recognition of the Company's federal NOLs and tax credits may be limited. Moreover, an ownership change might have also occurred under the laws of certain states and foreign countries in which the Company has generated NOLs and tax credits. Accordingly, it is possible that these NOL and tax credits could also be limited under rules similar to those of section 382. Due to the uncertainty surrounding the realization and timing of these tax attributes, the Company has recorded a valuation allowance of approximately $78.3 million and $92.4 million as of June 30, 2003 and 2004, respectively.

Certain amounts on the above tables have been reclassified to conform to the current presentation.

(10) Operating Leases

The Company leases its facilities and various office equipment under noncancellable operating leases with terms in excess of one year. Rent expense charged to operations was approximately

F-41

$12.3 million, $13.9 million and $11.7 million for the years ended June 30, 2002, 2003 and 2004, respectively. Future minimum lease payments under these leases as of June 30, 2004 are as follows (in thousands):

(11) Sale of Installments Receivable

Installments receivable represent the present value of future payments related to the financing of noncancellable term and perpetual license agreements that provide for payment in installments, generally over a one- to five-year period. A portion of each installment agreement is recognized as interest income in the accompanying consolidated statements of operations. The interest rates utilized for the years ended June 30, 2002, 2003, and 2004 ranged from 7.0% to 9.0%.

The Company has arrangements to sell certain of its installments receivable to two financial institutions. The Company sold, with limited recourse, certain of its installment contracts for aggregate proceeds of $66.7 million and $54.9 million during fiscal 2003 and 2004, respectively. The financial institutions have certain recourse to the Company upon nonpayment by the customer under the installments receivable. The amount of recourse is determined pursuant to the provisions of the Company's contracts with the financial institutions. Collections of these receivables reduce the Company's recourse obligations, as defined. Generally, no gain or loss is recognized on the sale of the receivables due to the consistency of the discount rates used by the Company and the financial institutions.

At June 30, 2004, there was approximately $50 million of additional availability under the arrangements. The Company expects that there will be continued ability to sell installments receivable, as the collection of the sold receivables will reduce the outstanding balance and the availability under the arrangements can be increased. The Company's potential recourse obligation related to these contracts is within the range of $1.4 million to $4.1 million. In addition, the Company is obligated to pay additional costs to the financial institutions in the event of default by the customer.

In December 2003, the Company entered into an arrangement to sell certain of its accounts receivable to a third financial institution, Silicon Valley Bank, pursuant to which the Company has the ability to sell receivables through January 1, 2005. Under this agreement, the total outstanding balance of sold receivables may not exceed $35.0 million at any one time. The Company has agreed to act as the bank's agent for collection of the sold receivables. During the year ended June 30, 2004, the Company sold receivables for aggregate proceeds of $42.5 million under this agreement. As of June 30, 2004 there was $5.0 million in availability.

(12) Commitments and Contingencies

(a) FTC complaint

On August 7, 2003, the FTC announced that it has authorized its staff to file a civil administrative complaint alleging that the acquisition of Hyprotech in May 2002 was anticompetitive and seeking to declare the acquisition in violation of Section 5 of the FTC Act and Section 7 of the Clayton Act. On July 15, 2004 the FTC announced that it had accepted a proposed consent decree for public comment. The public comment period ended August 13, 2004, and the FTC is currently considering whether to make the proposed consent decree final.

If the FTC approves the proposed consent decree in its current form, then the Company would be allowed to complete a sale to an FTC-approved buyer within 90 days of the order becoming final if it has entered into a definitive agreement with a potential buyer and submitted an application for approval of that buyer to the FTC within 5 days of the order being approved. If the Company has not identified a potential buyer, than it will have 60 days from the date on which the order becomes finale to complete the sale required by the order. If the Company fails to close a transaction within the 60 or 90 day timeframes, then the FTC may appoint a trustee who will be empowered to find an acquirer of the assets offered under the consent decree. The trustee will have an initial one year period to complete the sale. This period may be extended at the FTC's discretion for up to two additional years.

Under the terms of the published proposed consent decree the Company would sell its operator training services business and rights to the Hyprotech product line to an FTC-approved buyer, maintain certain technical standards with respect to the Hyprotech product line for 5 years, and provide the FTC-approved buyer of rights to the Hyprotech product line with all releases for the Hyprotech products for 2 years. The proposed consent decree provides for the Company to obtain rights to the Hyprotech products from the FTC-approved buyer. The Hyprotech product AXSYS was sold to Bentley Systems, Inc. in accordance with the terms of the proposed consent decree.

If the FTC does not approve a consent decree then it will likely return the case to litigation where an administrative law judge will adjudicate the complaint in a trial-type proceeding if the Company does not reach a settlement with the FTC prior to the conclusion of this proceeding. Any decision of the administrative law judge may be appealed to the commissioners of the FTC by either the FTC staff or the Company. Upon appeal, the commissioners will issue their own decision and order after reviewing legal briefs and hearing oral arguments. If the FTC commissioners rule against the Company, it may file a petition for review in a federal circuit court of appeals. If the court of appeals affirms the FTC's ruling, then the court will enter its own order of enforcement. Any decision of the court of appeals may be appealed by either the FTC, or by the Company, to the U.S. Supreme Court. The Company disagrees with the FTC that the acquisition of Hyprotech is anticompetitive and, if the matter returns to litigation, it intends to defend the proceedings vigorously.

It is not certain whether the FTC will approve the proposed consent decree in its present form or in an amended form acceptable to the Company. If the FTC approves a consent decree it is not certain whether the Company could successfully identify an acquirer acceptable to the FTC or negotiate acceptable terms. If the Company does not successfully close a transaction within the time periods set forth in the consent decree, then a trustee would be appointed by the FTC who could have up to three years to close a transaction. If the FTC does not approve a consent decree and the case is returned to litigation, then, because of the additional time to prepare for a trial, and the length of the appeals process, the final outcome of this matter may not be determined for several years. If the FTC were to prevail in this challenge, it could seek to impose a wide variety of remedies, some of which would have

F-43

a material adverse effect on the Company's ability to continue to operate under its current business plan and on its results of operations. These potential remedies include the divestiture of Hyprotech, as well as mandatory licensing of Hyprotech software products and other engineering software products to one or more of the Company's competitors. As of June 30, 2004, the Company had accrued $17.9 million to cover the cost of (1) professional service fees associated with its cooperation in the FTC's investigation since its commencement on June 7, 2002, and (2) estimated future professional services fees relating to negotiation of the proposed consent decree and implementation of the terms of a final consent decree.

(b) Litigation

On May 31, 2002, the Company acquired the capital stock of Hyprotech from AEA Technology plc. AEA is engaged in arbitration proceedings in England over a contract dispute with KBC Advanced Technologies PLC, an English technology and consulting services company. The dispute remains in arbitration and concerns alleged breaches by each party of an agreement to develop and market a product known as HYSYS.Refinery. The Company indemnified AEA under the Sale and Purchase Agreement with AEA dated May 10, 2002 against any costs, damages or expenses in respect of a claim brought by KBC alleging damages due to AEA's (a) failure to comply with its contractual obligations after the acquisition, (b) breach of non-competition clauses with respect to activities occurring after the acquisition, (c) breach of certain obligations to KBC under its agreement by virtue of the acquisition, or (d) execution of the acquisition agreement. On March 31, 2003, the arbitrator delivered a partial decision in the arbitration, as a result of which the Company has not received any request under the indemnification agreement, nor does it expect to receive one. On April 22, 2004 the arbitrator delivered a further partial decision stating that (a) the contract between AEA and KBC had been terminated and that AEA and Hyprotech were in breach of the non-compete provisions contained in that agreement, and (b) for a period of three years from the date of the award, Hyprotech shall not directly or indirectly sell or market a product which competes with HYSYS.Refinery. A further hearing is scheduled for December 2004, at which the arbitrator will determine whether there has been a breach by Hyprotech of obligations relating to confidentiality. The Company believes that no such breach occurred. The Company is working with AEA in the resolution of this matter. It is too early to determine the likely outcome of this matter.

In addition, on September 11, 2002, KBC filed a separate complaint in state district court in Houston, Texas against the Company and Hyprotech. KBC's claim alleges tortious interference with contract and existing business relations, tortious interference with prospective business relationships, conversion of intellectual property and civil conspiracy. KBC has requested actual and exemplary damages, costs and interest. The Company believes the causes of action to be without merit and will defend the case vigorously. Also, the Company has filed a counterclaim against KBC requesting actual and punitive damages and attorney fees. A trial date has been set for January 19, 2004. On August 25, 2003, KBC filed an additional complaint in the state district court in Houston, Texas against the Company and Hyprotech alleging breach of non-compete provisions and requesting injunctive relief preventing sale of the Company's product Aspen RefSYS. The Company believes the causes of action to be without merit and will defend the case vigorously. On September 15, 2003, the court set aside the application for injunction pending resolution of the arbitration in London. Following the London arbitrator's award of April 22, 2004 in relation to the non-compete, on May 7, 2004, the Houston court agreed to enter a judgment in Texas against Hyprotech on exactly the same terms as the arbitrator's

F-44

award against Hyprotech. The Houston court further stated that KBC may not bring any further claims against Hyprotech in Houston and that all such claims are reserved for the arbitrator in London. KBC has applied to the Houston court to have re-instated its application for injunctive relief against the Company. A hearing is scheduled for September 15, 2004 in Houston to resolve KBC's application. As of the filing date of this report, the Company has accrued $5.9 million to cover the cost of (1) professional service fees associated with our legal defense since its commencement and (2) estimated future costs relating to the matter.

(c) Other

The Company has entered into agreements with two executive officers providing for the payment of cash and other benefits in certain events of their voluntary or involuntary termination within three years following a change of control. Payment under these agreements would consist of a lump sum equal to approximately three times each executive's annual taxable compensation. The agreements also provide that the payments would be increased in the event that it would subject the officer to excise tax as a parachute payment under the Internal Revenue Code. The increase would be equal to the additional tax liability imposed on the executive as a result of the payment. The Company has entered into a substantially similar agreement with a third executive officer, except that payment under this agreement would consist of a lump sum equal to approximately (i) twice this executive's annual taxable compensation if he is terminated within the first year following a change of control and (ii) this executive's annual taxable compensation if he is terminated within the second or third year following a change of control.

The Company has also entered into agreements with four executive officers, providing for severance payments in the event that the executive is terminated by the Company other than for cause. Payments under one of these agreements consist of continuation of base salary for a period of 18 months, payments under two of these agreements consist of continuation of base salary for a period of 12 months, and payments under the fourth agreement consist of continuation of base salary for a period of six months.

(13) Retirement and Profit Sharing Plans

The Company maintains a defined contribution retirement plan under Section 401(k) of the Internal Revenue Code covering all eligible employees, as defined. Under the plan, a participant may elect to defer receipt of a stated percentage of his or her compensation, subject to limitation under the Internal Revenue Code, which would otherwise be payable to the participant for any plan year. The Company may make discretionary contributions to this plan, including making matching contributions equal to 25% of pretax employee contributions up to a maximum of 6% of an employee's salary. During the fiscal years ended June 30, 2002, 2003 and 2004, the Company made matching contributions of approximately $1.3 million, $0.1 million and $1.0 million, respectively.

(14) Joint Ventures and Other Investments

In May 1993, the Company entered into an Equity Joint Venture agreement with China Petrochemical Technology Company to form a limited liability company governed by the laws of the People's Republic of China. This joint venture has the nonexclusive right to distribute the Company's

F-45

products within the People's Republic of China. The Company invested $0.3 million on August 6, 1993, which represents a 25% equity interest in the joint venture as of June 30, 2004.

In November 1993, the Company invested approximately $0.1 million in a Cyprus-based company, representing approximately a 14% equity interest. In December 1995, the Company exercised its option to increase its equity interest to 22.5%, acquiring additional shares for approximately $0.1 million. In fiscal 2001, a third party invested in the entity and purchased a portion of the existing shareholders' equity interests. As a result of this transaction, the Company's equity interest increased to 31.58%.

The Company is accounting for the above two investments using the equity method. The net investments of approximately $0.7 million and $0.3 million are included in other assets in the accompanying consolidated balance sheets as of June 30, 2003 and 2004, respectively. In the accompanying consolidated statements of operations for the years ended June 30, 2002, 2003, and 2004, the Company has recognized losses of approximately $0.2 million, $0.5 million and $0.3 million, respectively, as its portion of the losses from these joint ventures. The Company does not have any commitments to provide additional funding to these entities.

In November 2000, the Company invested $0.6 million in a global chemical B2B e-commerce site supporting major chemical companies in Asia. This investment entitles the Company to a minority interest in the B2B company and is accounted for using the cost method and, accordingly, is being valued at cost unless a permanent impairment in its value occurs or the investment is liquidated. As of June 30, 2004, the Company has determined that an other than temporary impairment has not occurred. This investment is included in other assets in the accompanying consolidated balance sheet as of June 30, 2003 and 2004.

(16) Related Party Transactions

A director of the Company provided advisory services to the Company as a director of PetroVantage during fiscal 2002 and 2003. The Company made payments of $32,000 to the director as compensation for services rendered during fiscal 2002 and no payments in fiscal 2003. Separately, during fiscal 2003, the director provided general consulting services to the Company, for which the Company made payments totaling approximately $230,000 during the year.

(17) Segment and Geographic Information

The Company follows the provisions of SFAS No. 131, "Disclosures about Segments of an Enterprise and related Information," which establishes standards for reporting information about operating segments in annual financial statements and requires selected information about operating segments in interim financial reports issued to stockholders. It also established standards for disclosures about products and services, and geographic areas. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision making group, in deciding how to allocate resources and in assessing performance. The Company's chief operating decision maker is the Chief Executive Officer of the Company.

The Company is organized geographically and by line of business. The Company has three major line of business operating segments: license, consulting services and maintenance and training. The Company also evaluates certain subsets of business segments by vertical industries as well as by product categories. While the Executive Management Committee evaluates results in a number of different ways, the line of business management structure is the primary basis for which it assesses financial performance and allocates resources.

The license line of business is engaged in the development and licensing of software. The consulting services line of business offers implementation, advanced process control, real-time optimization and other consulting services in order to provide its customers with complete solutions. The maintenance and training line of business provides customers with a wide range of support services that include on-site support, telephone support, software updates and various forms of training on how to use the Company's products.

The accounting policies of the line of business operating segments are the same as those described in the summary of significant accounting policies. The Company does not track assets or capital

F-47

expenditures by operating segments. Consequently, it is not practical to show assets, capital expenditures, depreciation or amortization by operating segments.

The following table presents a summary of operating segments (in thousands):
