Overview

        We provide an integrated performance optimization software suite that enables global enterprises to capture customer intelligence and optimize workforce performance. Our solution is comprised of Voice over Internet Protocol ("VoIP") telephony, compliance, high-volume and business-driven recording solutions, as well as performance analysis and e-learning applications. Our eQuality® software suite delivers an integrated system for continuous performance improvement in multimedia customer interaction centers, Internet Protocol ("IP") telephony and back office environments to enhance the customer experience. These applications are designed to enhance the quality of customer interactions across multiple communications media, including the telephone, e-mail and the Internet, and are used primarily in the organization's contact center(s). Our enterprise collaboration architecture allows contact center management to share information gathered in the contact center with other departments that service the customer, as well as throughout the organization. The result is a proactive management tool for optimizing customer relationship management ("CRM"), improving communication among departments, and fine-tuning workflow, processes and quality of service from within the contact center and throughout the enterprise. As a result, we believe our customers are able to generate additional revenue opportunities, improve profitability, enhance customer retention, reduce employee turnover and improve their overall customer service.

        Our eQuality software suite is designed to enable customer contact centers within a company to capture, evaluate and analyze complete customer interactions through multiple media, identify performance gaps and then apply targeted electronic learning for continuous performance improvement. The eQuality software records a customer sales/service representative's ("CSR"s) voice interactions with a customer as well as the CSR's corresponding computer desktop activities, such as data entry, screen navigation and data retrieval. By capturing both voice and computer desktop activity and synchronizing them during replay, a company can observe and analyze complete customer interactions as they actually occurred. Supporting the need for Web-based customer interactions, the eQuality software suite also enables companies to capture, evaluate and analyze e-mail, Web interactions and guided browser sessions. In addition, the eQuality software suite allows companies to selectively capture, evaluate and analyze customer interactions on any of these mediums based on

1

business criteria that they define, such as key customers, important marketing campaigns and new product introductions.

        We sell our software solutions through a combination of our direct sales force and an indirect sales channel consisting of systems integrators, distributors, resellers and Original Equipment Manufacturers ("OEM"). We provide our solutions to an extensive base of large companies with multiple contact centers including Accor, Alliant Energy, American Airlines, Ameritrade, AT&T, Bristol Myers Squibb, British Telecom, Cable & Wireless, Canon Oceania, Centrica, Compaq Computer, Continental Airlines, Federal Express, GlaxoSmithKline, The Hartford Financial Services Group, Hertz, HSBC, Lloyds TSB, Medco Health Solutions, Inc., Mercedes Benz, Nokia, PacifiCorp, Pitney Bowes, Royal & Sun Alliance, Starwood Hotels & Resorts Worldwide, Target, Telstra, Verizon, Visa, Volkswagen, Wells Fargo Bank and Xerox. Our indirect sales channel is strategically focused on small to medium-sized businesses ("SMBs"), generally with single-site contact centers. Transactions with SMBs tend to be small in size and generate less revenue to us on an individual basis; therefore, it is more cost effective for our indirect sales channel to execute these orders.

Industry Background

        Developing and maintaining long-term customer relationships is critical to the success of a business operating in the competitive global marketplace. Because the Internet enables consumers to easily evaluate products and prices from a wide range of geographically dispersed vendors and quickly change vendors at relatively low cost, it is difficult for businesses to retain long-term relationships with their customers. Personal contact is essential to enabling a high quality customer experience. The integration and optimization of customer contacts across all channels of communication has become both a strategic and tactical business requirement. In response to these circumstances, companies adopt CRM initiatives to increase the longevity and profitability of their customer relationships, and continue to develop CRM software applications to automate and evaluate key sales, marketing and customer service processes and improve the effectiveness of their customer interactions. According to IT industry analysts at Gartner, Inc., "Organizations are moving to customer-centric models where efficiency is not as important as effectiveness. They demand accuracy and speed."

        The focus of CRM applications is to improve companies' internal sales, marketing and customer service processes and, resulting response to the competitive pressures generated from the Internet and e-commerce, to improve their ability to identify and address their customers' needs. Companies recognize that improving customer satisfaction and enhancing employee skills is an integral part of their goals to foster customer relationships and increase customer intimacy. We believe that companies, with a better understanding of the characteristics and preferences of their customers, will be able to customize their product and service offerings more effectively, which can result in increased customer retention. In addition, these companies will be able to better identify opportunities to sell complementary or higher-end products and to more accurately forecast customer demand.

        To understand and improve customer relationships, a company must first improve its specific business processes that involve direct customer interaction. Frequently, a company's direct customer interactions occur through contact centers. These contact centers traditionally are staffed by CSRs, who process a steady flow of outbound or inbound telephone calls relating to the company's products and services. The technical infrastructure of a contact center typically consists of supervisor and agent workstations linked to a central telephone switch and a common computer system.

        Contact centers are multi-functional, multi-channel customer interaction centers. Multi-channel customer contact centers conduct outbound calls for functions such as collections and product sales, or manage inbound calls, for purposes such as product support, order processing or customer service. They also handle multiple tasks effectively that involve interaction across a growing number of customer touch-points, including telephone, e-mail and the Web. According to Gartner, Inc., the

2

average cost of a Web-based self-service inquiry is a fraction of the cost of a call handled by a call center employee, illustrating why companies consider the deployment of Web-based self-service options a priority in their future customer care plans.

        Customer service is no longer a separate and distinct business function but an integrated set of business processes. Many organizations today have business plans that include creating a positive, consistent customer experience across channels and functions. Providing quality customer experiences remains an important goal for most organizations today. This focus is extending to many areas of the business as they embrace the technology to help identify the root cause of customer frustration.

        Companies have increased their focus on developing and improving the efficiency of their contact center operations. The current business environment is focused on performance improvement, particularly optimum customer service levels. Companies want to improve productivity and data quality, as well as audit capabilities needed to ensure adherence to processes, such as regulatory compliance and fraud reduction. By focusing on performance optimization, companies can better identify barriers and breakdowns, such as where and why errors occur, so they can make adjustments, often before errors affect customers. Our software enables these companies to help improve the quality and productivity of back office functions, such as customer administration and billing, while concentrating on providing high quality customer service. Using business rules, companies can automatically capture transactions placed into unique contact folders for specific business functions, and be notified when the specific business condition exists. Organizations can evaluate operational effectiveness, spot trends and implement tactics to improve performance. Desktop recording captures the screen navigation and exact keystrokes on employee desktops, so users can replay and evaluate transactions just as they occurred. Advanced recording capabilities enable users to define and maintain individual screen-based triggers, so they can capture specific business functions based on the values of individual fields within an application. Recording and reviewing transactions can provide valuable insight into the effectiveness of particular areas of the organization and its impact on the customer experience. By capturing sample transactions, companies can assess the ease with which staff completes processes and the effectiveness of systems. According to Datamonitor plc, quality monitoring (also known as quality management) is projected to grow on an average basis of 12 percent annually from 2003 to 2008.

        Certain companies might need to record 100% of all transactions for fraud detection or regulatory compliance. For example, companies may record all orders processed beyond a certain transaction amount or capture 100% of high-risk situations for audit purposes. According to DMG Consulting LLC, compliance recording (also known as logging) is projected to grow from 10 to 15 percent annually over the next few years.

        The convergence of voice and data communications technologies is changing the landscape of today's telecommunications infrastructure. VoIP is enabling smaller organizations to access application functionality previously afforded only by large organizations and is giving larger customers greater flexibility in their infrastructure, resulting in improved operational efficiency and significant cost savings. IP telephony is enabling the development of enterprise-wide contact management systems, which integrate the vast amounts of information from customers, suppliers or other third parties at every touch point or department primarily, but not exclusively, for the contact center. Interactions with customers and suppliers can include enormous amounts of valuable information that, if made available to the right people within an organization, may dramatically improve the service offered to customers. The information contained in telephone calls had previously been difficult to disseminate once captured.

        Our VoIP product consists of a recording subsystem that works with a variety of IP telephony contact center products that converts phone calls sent over those systems into stored audio files. These files can then be stored, archived, replayed and analyzed with our other eQuality products. Our technology is also capable of capturing other information related to a VoIP call, such as the time of the

3

call, dialed digits and date of the call for the purpose of providing the user with a simple method of cataloging and searching for VoIP recorded calls. VoIP call recording shipments are projected to grow on an average basis of 39 percent annually from 2003 to 2008, according to Tern Systems, Inc.

The eQuality Solution

        We provide business-driven multi-media recording, performance analysis and e-learning applications that are designed to enhance the quality of customer interactions across multiple communications media. As a result, we believe our customers are able to generate additional revenue opportunities, improve profitability, reduce employee turnover, enhance customer retention and improve overall customer satisfaction. We believe our eQuality suite of software and services provide the following key business benefits:

•

Increases revenue opportunities. The eQuality solution enables companies to analyze complete customer interactions, incorporating data from their existing databases and systems. As a result, companies are able to customize their sales and marketing efforts to individual customer preferences or tendencies, improve the selling techniques of their CSRs and sell additional complementary or higher-end products and services to their existing customers. Consequently, we believe companies deploying our solution can generate additional revenue opportunities.



•

Improves profitability. The eQuality solution improves the overall quality of companies' interactions with their customers, which reduces the costs associated with customer turnover. By providing CSRs with better training, companies can improve their efficiency by reducing their average customer response time, which results in a reduced total number of CSRs needed to handle the same volume of customer interactions and decreased telephony charges and other multi-media communication charges. As a result, we believe companies are able to improve profitability by deploying the eQuality solution to reduce customer turnover and CSR costs.



•

Reduces employee turnover. The eQuality solution enables the evaluation and analysis of an individual CSR's performance, which companies can use to customize incentives for rewarding CSRs. We believe these customized incentives, together with effective feedback and training, leads to increased CSR job satisfaction, retention of high quality CSRs and reduced costs related to CSR turnover. According to Forrester Research, the contact center average turnover rate ranges from 30% to 60% annually, and the costs to recruit, interview and train new CSRs are often as high as $10,000 per agent, depending on the level of skills required.



•

Enhances customer retention. The eQuality solution helps companies to develop more intimate knowledge of their customers, which should improve the overall quality of the information used to market products and services to customers. We believe that the Internet and e-commerce has increased the importance customers place on high-quality and consistent customer service. It is imperative that companies retain all of their customers, in order to improve the return on their investment in business development. We believe companies that deliver excellent service to their customers will develop longer-term, more profitable customer relationships.



•

Identify process breakdowns. By taking performance management to the back office, branch or remote office environments, companies can quickly identify process breakdowns, root causes for call volume spikes in the contact center and catalysts driving customer frustration. The eQuality solution is designed to help improve the quality and productivity of back office functions—such as order fulfillment, claims processing and billing—enabling companies to optimize customer service in the back office, as well as in traditional contact center and IP environments.

        We believe that we are able to provide key business benefits through the innovative features of our eQuality solution, which include the following:

•

Enables synchronized replay of voice and computer desktop data;

•

Provides an integrated, closed-loop environment for applying organizational learning;



•

Integrates with third-party software and hardware;



•

Provides an open architecture that scales to support small to large installations; and



•

Enables rapid deployment.

Our Strategy

        Our objective is to be a leading provider of software and services to global enterprises to help them improve everything from contact center customer interactions to underlying back office processes in order to optimize their workforce performance and capture customer intelligence by recording and analyzing customer interactions across multiple communications media, including telephone, e-mail and the Internet. Key elements of our strategy include the following:

•

Extend the breadth and depth of product offerings. We intend to continue to invest in research and development to enhance our current software suite and build or purchase new software applications (as with the Blue Pumpkin Software, Inc. ("Blue Pumpkin") acquisition in January 2005) to address the growing needs of companies that seek to better manage their customer relationships across multiple communications media, and improve their efficiency and effectiveness. We also intend to extend our Web-based capabilities, such as the recording and analyzing of integrated e-commerce, e-mail and voice interactions. The Blue Pumpkin acquisition expands our software and services by adding forecasting, scheduling, adherence and planning applications. Additionally, we expect to expand the number of third-party applications with which our software can integrate.



•

Increase sales to new and existing customers. A majority of our existing customers are large companies that have multiple contact centers. While we have been successful in penetrating these customers and installing our software at more than one contact center, we have many customers for whom we have not yet installed our software at all contact centers. We intend to capitalize on the success of our initial installations by emphasizing the scalability and rapid deployment of our software to increase the number of installations at existing customers' sites that have not yet installed our software. We also plan to continue pursuing new customer accounts with multiple contact centers through our existing sales force and our network of strategic relationships.



•

Expand international presence. We currently maintain sales forces in Australia, Brazil, Canada, China, Japan, Mexico, the Netherlands, South Africa and the United Kingdom as well as in the United States. We plan to expand our direct and indirect sales channels in these regions, with particular attention to areas that are actively adopting CRM and contact center software solutions.



•

Expand our indirect sales channel. We intend to expand and increase the strength of our indirect sales channel by continuing to enter into reseller, distributor, systems integrator and OEM arrangements with key vendors in the contact center workforce optimization market. We also intend to expand our network of business alliances, because we believe the demand for our software will increase as it becomes compatible with an increasing number of CRM, enterprise resource planning and Internet infrastructure applications. In addition, we believe the indirect sales channel is key to our success internationally and with SMBs.

Our Products

        The eQuality suite of products is comprised of the following applications, listed below and described by function. Prior to 2003, the vast majority of our software revenues were derived from our eQuality Balance and eQuality ContactStore products. During 2004 and 2003, approximately 18% and 13%, of our orders included products other than eQuality Balance™ and eQuality ContactStore and related products. As a result of our reliance on a limited number of products, any factors affecting the markets for those products could adversely affect our business, financial condition and results of operations. We believe our future success will depend on our ability to continue to enhance our current product offerings, such as our eQuality Office offering to avoid their obsolescence while we concurrently develop and introduce new products and offerings that keep pace with competitive and technological advances.

CAPTURE AND RETRIEVE

        eQuality ContactStore.    eQuality ContactStore records 100% of voice conversations between CSRs and their customers, along with the corresponding computer desktop activity, such as the CSR keystrokes and data input. This application is designed for organizations with high-volume recording requirements, including compliance recording and/or sales verification, in either traditional or IP telephony environments. eQuality ContactStore Plus provides a single solution for capturing customer intelligence. Users can record 100% of customer interactions, and then proactively organize them, based on business rules they define, into designated contact folders for easy access and replay. eQuality ContactStore Express is designed specifically for the needs of SMBs, branch offices or departments, providing a 100% recording solution that requires minimal technical skills to deploy and use.

        eQuality Balance™.    eQuality Balance records multimedia interactions, including traditional voice, Web chat, instant messaging, guided browser sessions and e-mail, based on user-defined business rules. The CSR's voice interaction with a customer can be synchronized with the CSR's corresponding computer desktop activities, such as data entry, screen navigation and data retrieval. This enables companies to evaluate the performance of CSRs, determine whether the necessary technology resources for customer support are available to the CSRs and ascertain whether the CSRs are making effective and efficient use of these resources. Supervisors can use this information to train CSRs, improve company systems and resources designed to support CSRs and enhance the quality of the services being delivered to customers.

        eQuality Evaluation™.    The eQuality Evaluation application facilitates the review, evaluation and scoring of CSRs, providing an immediate summary of a CSR's performance. Using eQuality Evaluation, CSR supervisors can build custom evaluation forms that are designed to collect information about aspects of a CSR's performance that are most important to them. Supervisors and others can input information regarding a CSR's performance into the form, which is then collected in a database. The collected information can be retrieved, presented in a summary format, analyzed and ultimately used to measure and improve a CSR's performance. eQuality Evaluation can reveal problem areas, issues, trends and opportunities. Supervisors and others with access to eQuality Evaluation can review CSRs' performance and determine opportunities to increase their skill levels through training. Supervisors can compare CSRs' performance to current goals and develop more realistic future goals. eQuality Evaluation has historically been, and will continue to be, licensed together with the eQuality Balance application.

        eQuality Office.    The eQuality Office offering is a combination of eQuality Balance, eQuality Evaluation, eQuality Focus and eQuality Producer, which helps companies audit critical business functions to better understand the inter-departmental impact back office functions have on customer service and satisfaction. eQuality Office also helps companies address specific "root causes" of

6

customer contacts into the contact center, enabling them to uncover data entry errors, compliance issues and ineffective processes.

REPORT AND ANALYZE

        eQuality Analysis™.    The eQuality Analysis application provides a more comprehensive analysis of customer interaction and CSR performance by bridging the disparate information systems of a company. Using eQuality Analysis, a company can combine data derived from eQuality Evaluation with data obtained from a company's other business systems, such as CRM and enterprise resource planning software and integrated telephony applications. Combining multiple sources of data from within the company into a common analysis and reporting system allows for a more thorough evaluation of CSR and overall contact center performance. Recognizing the importance of multi-channel contact centers, we have designed eQuality Analysis to integrate with business systems that collect data from a broad range of communications media. With its performance scorecard, contact center managers can obtain a quick, streamlined view of performance relative to strategic organizational objectives. The software leverages a variety of industry-accepted, best-practice key performance indicators ("KPIs") contained in eQuality Analysis and includes pre-defined KPIs as a foundation to build customized measures. Users can view data and drill up and down into an area of interest. eQuality Analysis produces a wide array of user-defined summary (historical and trend) and detailed analysis (adherence, productivity, quality and others) in a report, graph or exported medium. The solution's reporting, dynamic analysis and performance scorecard capabilities provide organizations with business intelligence that can lead to increased revenue, heightened service quality and improved operational efficiencies.

        eQuality Vision.    eQuality Vision enables the rapid search and retrieval of recorded customer interactions. With the solution's powerful data visualization capabilities, contact center management can pinpoint and view contacts of interest. Through its color-coding classification of calls based on nature and outcome, patterns and trends, key areas of interest are identifiable, providing unique visualization that allows users to search through contact recordings and focus on those of interest.

        eQuality CallMiner.    eQuality CallMiner extracts key information from recorded calls, either key words or phrases, using speech recognition. It evaluates each call and stores the relevant information in a data mart for detailed analysis and flags calls of interest for in-depth review.

        eQuality Focus.    eQuality Focus monitors desktop activities and provides graphical reports to illustrate which applications employees use, including how they use them, when and for how long. With this information, contact center management can gain an analytical view of desktop workflow, as well as whether business applications and productivity tools are correctly configured for optimum use.

LEARN AND TRAIN

        eQuality Now™.    The eQuality Now application delivers ongoing training tailored to CSR competencies, which helps companies build customer loyalty through a more highly skilled and motivated workforce. The electronic learning management software integrates with leading on-line learning products focused on CSR soft and hard skills. By recording customer interactions, evaluating CSR performance, and then using eQuality Now to prioritize training, contact centers have an integrated, closed-loop solution for applying organizational learning. The result is an effective environment for continuous performance improvement that helps companies ensure their customers receive consistent service across all touch-points.

        eQuality Courseware.    eQuality Courseware enhances the skills of CSRs with targeted learning that is delivered to the CSRs' desktops. eQuality Courseware includes a series of 35 lessons in seven contact center skill tracks.

7

        eQuality Producer.    eQuality Producer is a customized contact center e-learning solution that leverages real-life scenarios agents encounter on a daily basis to create company-specific content. eQuality Producer enables organizations to address skill deficiencies with e-learning based on actual customer interactions. Once produced, the content is readily available, creating a dynamic learning environment in which CSRs simulate customer contacts.

Services

        Our services organization, the Witness Services Network, provides an integrated implementation, training and business consulting methodology that supports an effective and rapid deployment of the eQuality suite enabling organizations to more quickly realize the benefits of our solution.

        The Witness Services Network addresses a wide variety of issues through these offerings.

•

The Witness Consulting Network is comprised of professional services, systems integration and business consulting services that enable customers to fully optimize our eQuality software suite, including evaluations of current technology in order to provide recommendations to our customers on processes that will enable them to achieve their organizational goals. Our implementation professionals work with the customer to build a solid technical infrastructure that supports the eQuality suite of applications. An initial implementation engagement is typically completed within 30 to 60 days from the date the software agreement is signed by a new customer, and involves the planning, configuration, testing and implementation of our software. Since the detailed project planning occurs during installation at the first site, we can typically implement our software at a customer's additional sites in five to seven days. Generally, the actual software installation takes three to five days. We utilize an interactive, Web-based project management system for deploying our software, Implementation Performance Management Online ("IPMO"). IPMO provides online access to information and updates, including project status, timelines, meeting logs, training and related documentation, which help facilitate communication and further streamline project management and implementation. Our business consulting services provide a series of workshops that focus on specific contact center business processes, performance optimization, calibration techniques, business utilization, business rule development and high-impact coaching. Our business consulting services enable our customers to identify and link key business drivers with CSR skills and behaviors, providing a blueprint for implementing a successful performance optimization strategy.



•

The Witness Learning Network encompasses our education services that are designed to teach customers, resellers and partners how to use our products and includes centralized training at Witness University, on-site training at the customer location, as well as certification programs, which can be accessed online. Training services include end-user coach training and system administration.



•

The Witness Support Network, including our Customer Interaction Center, provides support services for our customers that include regular software upgrades, access to a knowledgebase of product-related information, and 24 × 7 telephone, e-mail and online support. We provide a three-tiered support system in order to ensure the most effective and efficient support resolution. In addition, our customers can choose from two level support services plans depending on their support needs.

Customers

        Our customers include large Fortune 100 companies and small companies with a varying number of contact center sites and/or other business environments. Our customers come from the banking and finance, insurance, outsourcing, technology, retail, telecommunications, travel, hospitality, healthcare, automotive, publishing and utility industries. As of December 31, 2004, we had licensed our software to

8

approximately 1,400 customers at approximately 2,800 sites. To date, customer installations have ranged from small business IP deployments at a single-site contact center having 25 CSRs, to customers with 32 contact centers having an aggregate of approximately 16,000 CSRs. No individual customer accounted for 10% or more of our revenue in 2004, 2003 and 2002.

Sales and Marketing

        We sell our software through a combination of a direct sales force and an indirect sales channel consisting of systems integrators, distributors, resellers and OEMs. As of December 31, 2004, our sales organization operated in 26 offices throughout the United States and in Australia, Brazil, Canada, China, Japan, Mexico, the Netherlands, and the United Kingdom.

        Our direct sales force is responsible for pursuing qualified leads generated internally and also qualified leads provided by companies with which we have formal or informal referral arrangements. Our direct sales cycle typically begins with the qualification of a sales lead or the request for a proposal from a prospective customer. The sales lead, or request for a proposal, is followed by an assessment of the customer's requirements, a formal proposal, presentations and product demonstrations, site visits to an existing customer using the software, and contract negotiation. The initial sales cycle can vary substantially from customer to customer but typically lasts six months, and is considered completed with the signing of the contract. Historically, most of our customers have increased their use of the software to expand the number of CSR seats and applications at existing sites and to license additional contact centers, with a lesser incremental sales effort required for these follow-on orders.

        To expand the coverage and support of our direct sales force, we sell our products through our indirect sales channels. We identify prospective indirect sales channel participants based on the markets they serve and the desirability of their client bases as users of our products. Each of our relationships with channel participants is memorialized in a written agreement, none of which is individually material to our business. We enter into referral agreements with strategic partners, such as systems integrators, that identify customer referrals or sales leads and support us in the sales process in exchange for a referral fee that is paid upon completion of an end-user sale. Systems integrators are information technology ("IT") consulting service companies who recommend our products during client engagements.

        Our distributor agreements grant third parties the right to sub-license our software directly to end-users and through other resellers, and if certified by us, to provide installation and support services within a specified territory. By entering into a distributor agreement, distributors are able to purchase our products at a discount, which varies depending upon the volume of business they transact and their level of involvement in providing installation and support services.

        Our reseller agreements grant third parties the right to sub-license our software directly to end-users, and if certified by us, to provide installation and support services within a specified territory. Resellers are also generally entitled to purchase products from us at a discount based on the volume of business they do, their level of participation in the sales and pre-sales process and their level of involvement in providing installation and support services. Through OEM agreements, we co-develop products, which are sold by the OEM as part of their portfolio of products. Our distributor, reseller and OEM agreements are not exclusive and may be terminated by either party at any time.

        To support our indirect sales channel, we provide sales training, sales and marketing program support, collateral marketing materials, demonstration tools and ongoing relationship management so that our sales channel participants can more effectively educate potential customers about the benefits of our solution. In addition, we provide training to our distributors and resellers to enable them to provide installation services and end-user training for our products. Our sales channel participants can also access a "partner portal" on our Web site, where they can download marketing materials,

9

descriptions of our products, technical product information and educational materials, which facilitate meaningful sales and service.

        We also use a variety of marketing programs to build brand name awareness, as well as to attract potential customers. These programs include market research, product and strategy updates with industry analysts, public relations activities, direct mail and relationship marketing programs, seminars, trade shows, advertising, speaking engagements and Web site marketing. To support sales efforts, the marketing organization also produces marketing materials, including brochures, data sheets and other technical descriptions, presentations and demonstrations. As of December 31, 2004, we had 148 employees in our sales and marketing organization.

Research and Development

        We believe our software development capabilities are essential to our strategy of enhancing our core technology, developing additional applications, incorporating that technology and maintaining the competitiveness of our software. We devote a substantial portion of our resources to developing new software and features, extending and improving our software technology, debugging and quality testing our products and researching new technological initiatives in our market. We believe that our future success depends in part upon our ability to continue to enhance existing software, respond to changing customer requirements and develop and introduce new or enhanced software that incorporates new technological developments and emerging industry standards.

        As of December 31, 2004, we had 233 people (including 145 contractors located in the Asia-Pacific region) engaged in research and development activities. In April 2004, we began implementing a strategic initiative to significantly expand and improve our development capabilities by transitioning a portion of our development function to the Asia-Pacific region. As of December 31, 2004, we doubled our development capacity by adding the personnel in the Asia Pacific region and incurring approximately $4.5 million for equipment and duplicative ramp-up, salaries, training and severance costs associated with the development transition. Research and development expenditures for the years ended December 31, 2004, 2003, and 2002 were $20.9 million, $18.0 million and $15.1 million, respectively. We anticipate that our research and development costs as a percentage of total revenue will decrease in 2005 as compared to 2004.

Competition

        Our software and services compete in the emerging market for products that record and analyze customer interactions and provide electronic learning applications. This market is intensely competitive and experiences rapid changes in technology. We believe that we compete effectively and that we enjoy a competitive advantage based upon (1) the functionality and quality of our products, (2) the ease of use and ability of our products to operate with a variety of hardware and software products, (3) our ability as a single vendor to offer a full suite of applications, (4) our ability to implement our products quickly, (5) the responsiveness of our customer support, and (6) our reputation in the marketplace. Our competitors include:

•

quality monitoring suppliers to the call and contact center industry, which historically have been companies that develop voice-only recording software;



•

time division multiplexing and IP switch vendors that traditionally bundle competitive solutions;



•

traditional call logging vendors that have historically focused on providing products that record all phone conversations made by or to the user, including emergency services, such as 911, and verification and liability users, such as trading floors and stockbrokers;



•

electronic learning vendors that have historically provided a point solution that delivers training to customer service representatives;

10

•

reporting and business intelligence vendors that have historically provided a point solution focused on providing contact center performance reports to management;



•

systems integrators and consulting firms which design and develop custom systems and perform custom integration; and



•

new, larger or more established entities that may acquire, invest in or form joint ventures with providers of recording or performance enhancing software solutions, such as vendors of CRM products, computer telephony companies and computer hardware, software and networking companies.

        In addition, we have developed, and intend to continue to develop, relationships with companies that resell our software, companies that integrate the software with their technology and products and companies that provide us with customer referrals or leads. Some of these companies have similar, and often more established, relationships with our competitors, and may recommend the products and services of competitors to customers instead of our software and services. In addition, through their relationships with us, these companies could learn about our software and the market for our software and services and could develop and sell competing products and services.

        The principal competitive factors in our market include:

•

product performance, reliability and features;



•

user scalability and open architecture;



•

third-party integration;



•

quality and speed of product implementation;



•

ease-of-use for customers;



•

analytic capabilities of the product;



•

how quickly new products and product enhancements can be brought to market;



•

customer support; and



•

pricing of products and services.

        Our success will depend on our ability to compete effectively based on these factors. Further, we expect that competition will increase as other established and emerging companies enter our market and as new products, services and technologies are introduced. Increased competition may result in price reductions, lower gross margins and loss of market share. This could materially and adversely affect our business, financial condition and results of operations.

Proprietary Rights

        General.    Our success depends to a significant degree on the legal protection of our software and other proprietary technology rights. We rely on a combination of patent, trade secret, copyright and trademark laws and confidentiality and non-disclosure agreements with employees and third parties to establish and protect our proprietary rights. These measures may not be sufficient to protect proprietary rights, and we cannot be certain that third parties will not misappropriate our technology and use it for their own benefit. Also, most of these protections do not preclude our competitors from independently developing products with functionality or features substantially equivalent or superior to our software. Any failure to protect our intellectual property could have a material adverse effect on our business.

        Licenses.    Our licenses are designed to prohibit unauthorized use, copying and disclosure of our software technology. When we license our software to customers, we require license agreements

11

containing confidentiality terms customary in the industry in order to protect our proprietary rights in the software. These agreements generally warrant that the software will materially comply with written documentation. We assert that we own the software we distribute and have not violated the intellectual property rights of others. We license our products in a format that does not permit the users to change the software code. In addition, because we treat the source code for our products as a trade secret, all employees and third parties who require access to the source code are first required to sign non-disclosure agreements.

        Patents.    As of December 31, 2004, we had five U.S. and three international patents, and 15 patent applications pending in the U.S. and five patent applications pending internationally. There is no guarantee that the pending applications will result in issued patents or, if issued, will provide us with any competitive advantages. We cannot assure you that we will file further patent, trademark or copyright applications, that any future applications will be approved, that any existing or future patents, trademarks or copyrights will adequately protect our intellectual property or that any existing or future patents, trademarks or copyrights will not be challenged by third parties.

        Trademarks and service marks.    As of December 31, 2004, we had seven registered trademarks and one trademark application pending in the U.S. We also claim common law protections for other marks we use in our business. Competitors and other companies could adopt similar marks, or try to prevent us from using our marks, consequently impeding our ability to build brand identity and possibly leading to customer confusion. We are aware of certain uses, U.S. trademark registrations, and U.S. trademark applications for our "eQuality" trademark and its variations that predate our use and the April 30, 2002 issuance of the U.S. registration for our trademark eQuality®. It is possible that the owner of legal rights resulting from one or more of these prior uses, U.S. trademark registrations, or U.S. trademark applications will bring legal action to challenge our registration of and/or our continued use of the trademark eQuality®, and may also seek compensation for damages resulting from our use of our registered trademark if such challenging party prevails on such a claim. As a result, we cannot assure you that our registration of this trademark will be undisturbed, or that this use will not result in liability for trademark infringement, trademark dilution, and/or unfair competition.

Item 2. Properties

        Our principal administrative, marketing, product development, training and support facilities are located in Roswell, Georgia, a suburb of Atlanta, where we lease approximately 96,400 square feet under a lease that expires in 2007. We occupy approximately 26,000 square feet in Leatherhead, United Kingdom under a lease that expires in 2014, which includes administrative, marketing, product development and support facilities. In addition, we lease a total of 30 offices in the United States, Australia, Brazil, Canada, China, Japan, Mexico, the Netherlands, Singapore and the United Kingdom. We believe our facilities are adequate for our current and expected near-term requirements.

Item 3. Legal Proceedings

        From time to time we may be involved in legal proceedings and/or litigation arising in the ordinary course of our business.

        On December 11, 2002, we filed in the United States District Court for the Northern District of Georgia, Atlanta Division, a lawsuit against Knowlagent, Inc. ("Knowlagent"), which is the assignee of the United States Patent Nos. 6,324,282 B1 and 6,459,787 B2. Knowlagent has accused our eQuality Now software of infringing the above patents. We filed suit seeking a declaration that we did not and do not infringe either of the two patents listed above, as well as a declaration that the above patents are invalid and unenforceable. We also filed a claim requesting that if the patents are found to be valid, that one of our own employees be named the rightful inventor of the patents. We also requested monetary damages in an amount equal to the amount that Knowlagent has received from its use of the above patents. On December 31, 2002, Knowlagent filed its answer to our complaint as well as two counterclaims, alleging that we infringe and contribute to the infringement by others of the above patents; Knowlagent seeks both monetary damages and an injunction in connection with its counterclaim. We are currently in the discovery phase of the lawsuit and believe that any adverse outcome would not have a material impact on our financial position, results of operations or cash flows.

        On July 20, 2004, STS Software Systems Ltd. ("STS Software"), a wholly-owned subsidiary of NICE Systems, Ltd. ("NICE Ltd."), filed a patent infringement suit in the U.S. District Court for the Southern District of New York against us ("New York Action"). The New York Action asserts that our products, including eQuality ContactStore for IP, infringe U.S. Patent No. 6,122,665 ("the "665 patent"). On the same day, we filed a declaratory judgment action against STS Software in the U.S. District Court for the Northern District of Georgia ("Georgia Action"). We seek a declaration from the court that we have not infringed any valid claim of the "665 patent. By Order entered December 16, 2004, Judge Koeltl of the U.S. District Court for the Southern District of New York granted our motion to transfer the New York Action to the Northern District of Georgia, which has now consolidated the former New York Action with the Georgia Action. The case has not yet been set on a discovery calendar and is at the most preliminary stage. We currently believe that any adverse outcome would not have a material impact on our financial position, results of operations or cash flows.

        On August 30, 2004, we filed in the United States District Court for the Northern District of Georgia, Atlanta Division, a lawsuit against NICE Systems, Inc. ("NICE Inc."), a wholly-owned subsidiary of NICE Ltd., alleging patent infringement. Specifically, we have alleged that NICE products, including the NiceUniverse products that include screen capture and synchronized screen and voice capture technologies, infringe claims of U.S. Patent Nos. 5,790,798 ("the "798 Patent") and 6,510,220 ("the "220 Patent"), both entitled "Method and Apparatus for Simultaneously Monitoring Computer User Screen and Telephone Activity from a Remote Location." We have sought an injunction and money damages for NICE's infringement of these two patents. NICE Inc. has answered and counterclaimed for declaratory judgments of non-infringement and invalidity. This suit is at the most preliminary stage.

        We are not party to any litigation or other legal proceedings that we believe could have a material adverse effect on our financial position, results of operations or cash flows.

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

        No matters were submitted to a vote of security holders during the fourth quarter ended December 31, 2004.

Trading plans provide for sales, subject to price restrictions, daily limits and other contingencies, of shares of our common stock.
