PART I. ITEM 1. BUSINESS GENERAL VTEL Corporation (VTEL, we or our) designs, manufactures, markets and supports visual communication systems. VTEL's product line is based on the latest microprocessor technology, a unique integration of hardware and software that provides features which are far beyond traditional video and audio conferencing. The use of open PC architecture and standard Microsoft(R) operating systems allows users to bring virtually any kind of data into a meeting or training environment. These new visual communications systems allow access and sharing of any information available on the World Wide Web, data that resides on an organization's Local Area Network or Intranet, or local PC files and software applications. The majority of our systems are built upon a system platform that is based on industry-standard, PC-compatible open hardware and software architecture. The PC-architecture also provides a natural pathway to connect VTEL's visual communication systems to either Internet Protocol (IP) networks or traditional telephone networks on a call by call basis through simple software commands. Our network management software uses industry standard protocols to allow large visual communications networks to be operated in the same manner currently used in traditional data networks, thereby leveraging the rapidly expanding network infrastructures being deployed in organizations throughout the world. VTEL's streaming video software allows users to "webcast" events live over an internal network or the Internet and store any multimedia content for convenient, on-demand playback. We offer a wide range of global professional services to assist customers in designing, installing, operating and supporting organizational visual communications networks worldwide. The cornerstone of VTEL's business strategy is to identify end-user customer markets that can most benefit from the advanced functionality of our multi-media visual communication systems and to focus a substantial portion of its sales and marketing efforts on these targeted markets. Consistent with this strategy, VTEL has targeted the manufacturing, education, government, health care, and financial institution market segments and certain portions of the general business market. VTEL primarily distributes its systems through third-party resellers which include major telecommunications providers and distributors such as Ameritech, Bell South, GTE, MCI, Norstan, PacBell, SBC, Sprint, US West and other value-added resellers. We have built an extensive marketing and sales organization to support our third-party resellers. This organization provides marketing programs; field support personnel including sales managers, system engineers, and business development managers; and personnel with industry expertise to implement our targeted market strategy. Since VTEL's inception, it has sold more than 30,000 visual communication systems. On May 23, 1997, shareholders of VTEL and Compression Labs, Incorporated, a Delaware corporation ("CLI"), approved the merger of VTEL-Sub, Inc., a Delaware corporation and direct wholly-owned subsidiary of VTEL (the "Merger"), with and into CLI, pursuant to an Agreement and Plan of Merger and Reorganization, with CLI becoming a direct wholly-owned subsidiary of VTEL. As a result of the Merger all of the outstanding common and preferred CLI shares were exchanged for a total of 8,424,741 shares of VTEL Common Stock. The acquisition was accounted for as a pooling of interests. On March 9, 1999, VTEL completed the acquisition of substantially all of the assets of Vosaic LLP, an Internet video software and technology company for $3.2 million in cash, stock and warrants. The transaction was accounted for as a purchase of assets. The acquisition involved the issuance of 1,149,000 shares (equivalent to approximately 5% of the outstanding shares of VTEL's stock as of March 9, 1999). VTEL acquired the core team, originally associated with the University of Illinois, who pioneered the first multimedia Web Browser, and has refined scalable video delivery technologies to stream and store video information securely with high Quality of Service (QoS). As part of VTEL's initiative to expand its international presence, we consummated the acquisition of certain of the assets of the videoconferencing division of one of our German resellers effective July 1, 1998. The 2

consideration paid by VTEL consisted of restricted stock, warrants, a note payable, and the assumption of certain payables and other liabilities for total consideration of approximately $1,871. In September 1998, VTEL compl- eted the acquisition of one of its French resellers through the issuance of res- tricted stock. VTEL's executive offices are located at 108 Wild Basin Road, Austin, Texas 78746, and its telephone number is (512) 437-2700. INDUSTRY BACKGROUND Visual communications systems enable users at remote locations to meet and share information face-to-face. A wide range of business or professional meetings, education and training classes, and technical or medical consultations make use of this innovative technology to reduce operating costs, improve customer services, reduce cycle times, and improve intra- or inter-company communications. A videoconference entails the transmission of video, audio and data signals between two or more locations over a network connection. Video, audio and data conferencing involves a large amount of digital information. In order to transmit this information over digital networks, the video, audio and data signals must be digitized and compressed without substantially reducing the information content. Improved compression algorithms reduce transmission costs by allowing more information to be sent over lower capacity digital networks. Improved quality and lower costs of videoconferencing systems and network services have made videoconferencing applications more attractive to a broader group of users worldwide. Also contributing to the wider use of videoconferencing is the increased availability of switched digital telephone service and the use of Internet Protocol networks, allowing a videoconference to be initiated with nearly the ease of a normal telephone call. The major change occurring in the industry today involves the evolutionary migration of telecommunications networks from circuit-switched technology (like traditional telephone lines) to packet-switched technology (Internet Protocol networks). We are ideally positioned to take advantage of this change because our underlying product technology is built upon an open PC architecture. In October 1999, VTEL introduced its new product line of Galaxy(TM) visual communication systems. The enhanced software included in the Galaxy(TM) line can accommodate and support customer migration to Internet Protocol networks easily because these endpoints can operate on either type network and move from one network architecture to another on a call by call basis through simple software commands. For many customers that previously purchased VTEL products, the migration to Internet Protocol network functionally can be accomplished through software upgrades to existing products. Videoconferencing systems are also becoming simpler to use. Current videoconferencing systems can be configured as "set-top" appliances or "roll-about" room systems that can be used without the need for trained operators or special room requirements. In general, the videoconferencing market can be grouped into four complementary categories: personal conferencing, set-top conferencing, workgroup conferencing, and group conferencing. The personal conferencing market is targeted at the individual. As such, solutions are typically priced in the $1,000 to $7,000 range. The set-top conferencing market is targeted at groups of two to three individuals. Systems in this market range from $4,995 to $9,000. The workgroup conferencing market is targeted at the project teams or executive offices that require collaborative data and software interaction. Solutions in this market range from $9,995 to $15,000. The group conferencing market is targeted at larger groups, typically eight or more individuals. Application uses vary greatly from boardrooms to large classrooms. These group systems are priced at $8,500 and above. Another factor contributing to the growth of videoconferencing is the continuing emergence of international industry standards designed to allow interoperability of videoconferencing systems manufactured by different vendors. The International Telecommunications Union ("ITU-T") sets international standards used by the industry. VTEL has been a leader in promoting standards across the industry and delivers standards-based products to its customers. 3

While technological advances and market receptivity have increased the use of videoconferencing, traditional audio and video videoconferencing alone lacks the functionality and effectiveness of face-to-face meetings in many applications. We believe that, for certain applications, users are seeking conferencing features, in addition to audio and video, that allow for the exchange of information and interaction through a variety of media. For example, engineers can communicate and solve problems more effectively by supplementing the videoconference with shared media, such as graphics with annotations, computer programs, document exchanges and whiteboards, which results in a better replication of the impact and effectiveness of a face-to-face meeting. VTEL has taken a leadership position in this form of high-value visual communication technology due to its open PC platform and flexible architecture. CORPORATE STRATEGY VTEL's primary focus is on high-value visual communication systems which provide high functionality tailored to the needs of our targeted markets. This results in a range of offerings from desktop to boardroom applications. The following are the components of VTEL's corporate strategy: PRODUCT DIFFERENTIATION. VTEL's strategy is to differentiate its products from the products marketed by its competitors. Key elements of this strategy are as follows: Open Architecture. VTEL's principal visual communication systems are built upon a system platform which integrates video, audio and data compression technologies in a PC-compatible open hardware and software architecture. This open architecture allows VTEL to accelerate the development process through the use of commonly available, low-cost hardware and software components and the incorporation of third-party technological developments. VTEL's PC-based system platforms are field-upgradable and easily accommodate software upgrades, thereby extending the useful life of the customer's investment and providing us with incremental revenues through these upgrade sales. In October 1999, we began shipping our Galaxy(TM) line of visual communication systems. The new line is distinguished by a new more intuitive user interface software (Vtouch TM) that offers the additional functionality of H.323 (or Internet Protocol) networking capability. Because VTEL's systems are PC-based, existing customers of our later generation ESA(TM) line of visual communication systems will be able upgrade to the latest features of the Galaxy(TM) line. Centralized Management and Administration. Using the industry standard Simple Network Management Protocol ("SNMP"), VTEL is able to centrally manage and administer large, distributed visual communication networks. VTEL's SmartVideoNet Manager product provides advanced functionality for management in the videoconferencing industry. It leverages the industry standard SNMP for statistics, controls, and alerts. These functions allow for centralized problem determination and resolution, thereby eliminating the requirement for on-site expert personnel to support the system. An additional benefit of SmartVideoNet Manager is the ability to establish video calls from a centralized console with no local user intervention. Using this, meeting participants simply arrive at the conference room or classroom and the video call is already in session waiting for their participation. Consistent Operating Platform. An important characteristic of each product in the family is the consistent use of standard Microsoft operating systems (Windows 95(R), Windows 98(R), Windows NT(R)). This consistency combines the PC-microprocessor architecture with a recognized software platform and provides a familiar look and feel for the user throughout the product family architecture. Windows operating systems support a wide variety of software and hardware applications that can be integrated into a videoconference as stand-alone features or as shared applications by visual communication users through our collaboration capability. Multi-media Functionality. VTEL's visual communication systems provide a wide range of functions that utilize a variety of media and more closely replicate the impact and effectiveness of face-to-face meetings. These functions, referred to by VTEL as visual communications technology, combine video and audio, document exchange, 4

shared whiteboard and computer application sharing. VTEL strives to make this functionality easily accessible to the user. Our Pen Pal Graphics and AppsView(TM) user interfaces were designed to make our group systems easier to use and are fully integrated on VTEL Team Conferencing and Leadership Conferencing systems. Galaxy's(TM) new Vtouch(TM) graphical user interface builds upon the success of these earlier efforts to provide even easier system operation. Both AppsView(TM) and Vtouch(TM) are customizable user interfaces that run on a Microsoft Windows(R)operating system. They integrate all application functions under a software defined interface which can be customized by the user to meet specific needs. Standards Compliance. VTEL believes the continued adoption and implementation of industry standards for interoperability are critical to the continued growth of the videoconferencing market. All of our visual communication systems and multipoint products comply with the leading ITU-T standards for videoconferencing. VTEL's platforms also comply with an extensive array of additional communications and computer industry standards, both formal and de facto (such as ISA, PCI, Intel x86, SNMP, and Microsoft Windows(R)), involving video, audio, graphics, communications, computers, peripherals, and network management. We have been an active participant on the relevant ITU-T committees and intend to continue to promote both acceptance of the standards by all vendors and formal compliance testing to assure interoperability. Network Integration Capabilities. The PC-based open architecture design of VTEL's products provides a natural pathway to connect our visual communication systems onto local area networks (LANs) and wide area networks (WANs), thereby leveraging the rapidly expanding network infrastructures being deployed in organizations throughout the world. We believe that not only will such networks continue to expand globally, but the capability to centrally manage large internationally dispersed networks will become a requirement for the successful establishment of such networks. We believe that development of network integration and network management capabilities will be an important success factor to our strategy. The VTEL Network Assured Program was initiated with the goal of ensuring interoperability between the various networking systems in the marketplace and VTEL's videoconferencing equipment. This program offers the customer, who must interface with the different major equipment vendors, the peace-of-mind they are seeking as they integrate multivendor equipment on a network. To facilitate an easy migration into the new realm of IP communications, VTEL is collaborating with vendors of network services including Cisco, GTE Network Services, IXC Communications and Ezenia! to enable seamless integration between VTEL's H.323-based product line and their product line. Service and Systems Integration Capabilities. VTEL's Global Services division offers installation, integration and support services to customers of its products. Most sales occur through resellers to the end users of our products. This offering of services enhances VTEL's resellers' ability to sell our visual communication systems and to generate additional revenues to VTEL from the sales of such services. During fiscal 1999 Global Services expanded the capabilities offered to our resellers by building application-specific systems that address individual users' needs. This service excelled where resellers expressed the need to deliver a system requirement that could be duplicated many times within a market or region. Projects were typically priced in the range of $100,000 to $300,000. The building of application-specific systems for a reseller further differentiates VTEL and its hardware/software solutions. VTEL intends to expand in this area in fiscal year 2000. TARGETED MARKETS. The cornerstone of VTEL's business strategy is to identify end-user customer markets that can most benefit from the advanced functionality of our multi-media visual communication systems, and to focus a substantial portion of our sales and marketing efforts on these targeted markets. Consistent with this strategy, VTEL has targeted the manufacturing, education, government, health care, and certain portions of the business market. VTEL continues to focus on those markets in which it has the highest potential for increasing its market share. We currently enjoy a leadership position in the education market with installations at secondary and higher education systems throughout the world. 5

DISTRIBUTION STRATEGY. VTEL believes that a well-executed distribution channel is critical to marketing success. VTEL currently relies on third party resellers to sell, install and support its visual communication systems in an effort to leverage the sales forces of the resellers that are already providing telecommunications and systems integration services to potential purchasers of visual communication systems. All major resellers maintain demonstration networks, with trained sales and support personnel. Consistent with its focus on its targeted market segments, we work with a number of VARs that specialize in specific applications, geographic areas and markets such as education, health care, project management and government procurement. Typically, VTEL's agreements with its resellers and VARs involve non-exclusive arrangements which may be canceled by either party at will and contain no minimum purchase requirements on the part of the resellers. VTEL also sells products directly to certain end-user customers, generally large global end user customers which have sophisticated global visual communication networks and require much more involvement to support the sale, installation and maintenance of the network. These sales are mostly completed through VTEL's Global Service division. PRODUCTS We offer a complete line of interoperable multi-media visual communication systems. VTEL differentiates its systems from competitive products by a high level of advanced functionality, such as presentation graphics and access to PC-based software and hardware peripherals. Because VTEL systems are based on open PC-architecture, and most functionality is contained in software, many system upgrades are accomplished via software, enabling customers to protect their investment in our systems. VTEL systems may be configured with LAN connections so that data and presentations may be created at an individual PC workstation, stored on the LAN and retrieved by the visual communication system for presentation or transfer to the remote location during a videoconference. Videoconferences can range from simple point-to-point connections between two locations of a single organization to connections between multiple locations of multiple organizations in several countries. VTEL's primary visual communication products are based upon one of three architectures, the SmartStation Architecture (SSA) for personal and workgroup visual communication, the Enterprise Series Architecture (ESA) for group conferencing, and the TurboCast(TM) Architecture for Internet targeted visual communications solutions. ENTERPRISE SERIES ARCHITECTURE PLATFORM. VTEL's Enterprise Series Architecture(TM) ("ESA") is the hardware and software platform for a family of products designed to meet the needs of large and small groups. The ESA platform is a PC-based, open architecture visual communication system configured around an Intel Pentium(TM) PC chassis containing the ESA(TM) video-audio processing boardset. The ESA(TM) system contains, in addition to the standard internal disk drive and 3.5 inch floppy drive, a CD-ROM drive as well as an expansion chassis which contains all the audio and video input/output ports. The ESA(TM) platform utilizes the Microsoft Windows(R) operating system as its software platform and incorporates either the AppsView(TM) software user interface and control system or its newly released Galaxy(TM) Vtouch(TM) software user interface and control system. Through AppsView(TM) or Vtouch(TM), the user controls all conference functions with on-screen software icons which may be customized for each user or application. The ESA platform contains open PC card slots for application-specific peripherals. The ESA(TM) platform supports industry standards for video, audio and data compression and is interoperable with any other system supporting the H.320 standard using the AppsView(TM) software, and both H.320 and H.323 using the Galaxy(TM) software . The platform operates over digital communication bandwidths transmitting at data rates from 56 Kbps to T1 or E1 rates in point-to-point and multipoint conferences. ESA connections can be made over public dial-up digital networks or private digital dedicated facilities. During fiscal 1999, ESA connectivity was expanded to include Internet Protocol networks through a hardware addition. ESA systems may also be upgraded to H.323 (Internet Protocol) with our new Galaxy(TM) software. 6

Configurations of the ESA(TM) platform with AppsView(TM) include VTEL's Team Conferencing(TM) ("TC") and Leadership Conferencing(TM) ("LC") Systems. These systems are single or dual monitor systems built on the ESA platform and designed to provide mid-range products for users seeking high quality video and audio and visual communication capability in a small to mid-sized group setting. Data rates from 56 Kbps to 512 Kbps are provided on all systems and high speed data rates up to T1 or E1 for the high end LC systems. The systems provide higher performance PC-based functionality through the use of the Intel Pentium(TM) microprocessor, inclusion of a CD-ROM drive, the Microsoft Windows(TM) operating system and the AppsView(TM) user interface. Product features include LAN connectivity, Internet access, both document and computer conferencing, 30 frame per second video and capability of including software applications designed for Microsoft Windows(TM) as part of the videoconference. The TC systems have suggested list prices of $11,700 to $40,995 and LC5000 configurations vary in price from $54,995 to $59,495 Configurations of the ESA(TM) hardware platform with Galaxy(TM) include several new Products: Galaxy Model 725, Galaxy Model 755, Galaxy Model 2500 and Galaxy Model 5500. This new family of products provide the competitive price performance characteristics required by customers across the wide range of group system applications. The products provide state of the art video and audio with high resolution slide capture and send graphics. The systems are H.323 capable for videoconferencing over Internet Protocol Networks and/or H.320 capable for videoconferencing over traditional circuit switched networks. Within this product family there are solutions that support single or dual monitor configurations, and data rates from 56kbps to 1920Kbps (T1/E1). All are supported by the new Vtouch(TM) graphical user interface. WG500. The WG500 is a series of workgroup visual communication systems targeted at the project team or executive office where the ability to share and interactively create a work product is required. As such, it is designed to utilize industry leading collaborative multi-media tools such as Microsoft NetMeeting(TM). Based on a high performance, multi-media PC platform, the WG500 fills the price-point and functionality gap between the personal desktop conferencing market and the large group conferencing market. The WG500 has suggested list prices of $9,995 to $14,995 SETTOP 250. The SETTOP 250 was the first business-class, set-top videoconferencing system in the industry priced under $5,000. Combining ease-of-use with high-quality features, the SETTOP 250 is the solution for enterprise users who require entry-level group conferencing with industry-standard voice and video. The SETTOP 250 includes an intuitive user interface, an easy, color-coded installation process, and comes in both 128 Kbps and 384 Kbps models. SMARTSTATION. The SmartStation(TM) converts a Windows-based PC into a videoconferencing system for personal use. Incorporating the performance of the ESA(TM) products with its high-quality audio and video, the SmartStation(TM) allows users to collaborate while still leveraging the power and versatility of their desktop PC. In one easy-to-install package, SmartStation(TM) includes VTEL's AppsView(TM) graphical conference control interface for consistent operation across many of VTEL's visual communication solutions. SmartStation(TM) supports data rates up to 384 Kbps for high-quality desktop conferencing and supports the T.120 standard for data collaboration by integrating Microsoft NetMeeting 2.0(TM). SMARTVIDEONET MANAGER(TM). SmartVideoNet Manager(TM) software is a tool designed to help customers simplify the administration of video networks and reduce the operating costs. Based on the Windows NT platform and utilizing the SNMP communications protocol, SmartVideoNet Manager(TM) leverages the PC-based architecture of our systems to allow customers to use their existing Intranet to provide continuous monitoring of their video network. SmartVideoNet Manager(TM) allows administrators to remotely control, configure, diagnose and troubleshoot VTEL systems, all from a PC console. NETWORK EQUIPMENT. VTEL carries an extensive line of equipment to optimize connectivity in a variety of network environments. In order to maximize communication effectiveness, many customers choose to purchase multipoint control units to link multiple users into a single meeting. The SmartLink 7

Multimedia Conference SERVER(TM) ("MCS") is the hub of a videoconferencing meeting, allowing interactive communications with up to 48 participants. The SmartLink MCS(TM) provides translation capabilities for a number of line rates and video and audio algorithms to ensure maximum flexibility. Additionally, the SmartLink MCS(TM) is manageable through SmartVideoNet Manager(TM). SmartLink MCS(TM) configurations range in price from $19,480 to more than $150,000 for advanced configurations. TURBOCAST. The TurboCast(TM) software allows customers to capture, store, distribute, and view media streams across the Internet and to be accessed by clients using standard web browsers. The TurboCast solution consists of three principal components: Studio, Reflector, and Viewer. The Studio and Reflectors work together to capture and distribute live or stored multimedia content. The TurboCast Viewer, implemented as a lightweight Java(R) applet, allows a media stream to play directly within browsers such as Microsoft Internet Explorer(R) and Netscape Navigator(R), without downloading additional software. Since TurboCast(TM) can be used with any Java(R)-enabled browser, broadcasts can be viewed on PC, Macintosh and Unix systems as well as some Java(R)-based hand-held consumer devices. Current TurboCast products include: TurboCast Studio which allows events to be captured for live broadcasts or time-shifted replays using a standard video camera and PC or VTEL's Enterprise Series videoconferencing systems. PRODUCT DEVELOPMENT VTEL's product development strategy is to design and develop core systems capabilities and leverage the availability of hardware peripherals and application software from third parties and to efficiently integrate such third party resources into its systems. Additionally, with the acquisition of the Internet streaming technology obtained with the purchase of Vosaic, we intend to continue to introduce products that incorporate streaming technology. To the extent that market needs cannot be met by available third party resources, we may undertake the development of such resources. The following represent development efforts that have been undertaken by VTEL: SOFTWARE SYSTEM PLATFORM. The SmartStation(TM) Architecture and ESA(TM) hardware platforms support our proprietary software architectures. The characteristics of our products are developed and implemented primarily through software, facilitating upgrades for users and the rapid incorporation of new technologies. Upgrades are modular in nature, allowing additional licensed program products to be added incrementally to the user's basic system. Our software products are developed primarily in "C", a commonly-used, high-level programming language, to provide future portability to other hardware platforms. Development resources are being applied to the creation of new system software and program products for increased functionality and flexibility of the platform. PERSONAL VISUAL COMMUNICATION SYSTEMS. Increased performance of semiconductor processors specifically designed for video and image processing allow for the cost-effective design and packaging of small group visual communication systems and high functionality personal desktop systems that are compatible with small and large group visual communication systems. We introduced the SmartStation(TM) visual communication cardset which was developed utilizing the capability of our visual communication software ported to a suitable hardware platform. The principal hardware-related resource commitment in the development process is the effort to find and test boardset candidates for suitability for VTEL's software. AUDIO COMPRESSION/ECHO CANCELLATION. Audio quality is an important element in any video conference. At lower transmission rates, the amount of bandwidth allocated to audio decreases, thereby requiring audio compression algorithms to maintain acceptable audio quality. VTEL produces its own proprietary, integrated echo canceller to improve audio quality. We offer audio compression capability at allocated bandwidths of 8, 12, 32 and 74 Kbps through audio subsystems. VIDEO/IMAGE COMPRESSION. VTEL's continuing video compression development activity is focused on the refinement of both H.320 and H.323 algorithms for higher resolution video capabilities and the integration of that technology. Shortly following the merger with CLI in 1997, VTEL announced 8

StandardsPlus(TM) Video which provides improved video quality using industry standards. Significant video quality improvements using industry technology standards were achieved via a collaborative development effort between VTEL engineers in Austin and Sunnyvale. NETWORK MANAGERS. In the summer of 1997, VTEL introduced the industry's first standards-based management and administration platform for distributed visual communication networks. Using the SNMP standard, SmartVideoNet ManagerTM allows VTEL customers to centrally control their visual communication network for functions such as problem determination, problem resolution, call setup and conference statistics. Using this management framework, conference support can be provided centrally with no requirement for local user intervention, even for networks with hundreds of visual communication system endpoints. INTERNET TECHNOLOGIES. In 1999 VTEL launched several development initiatives aimed at harnessing the emerging power of the Internet with its associated technologies. The Internet will benefit VTEL on several fronts. First, as a widely distributed and accessible "data network", the Internet eventually will surpass in usage any data communication infrastructure based on dedicated transmission media, initial bandwidth limitations notwithstanding. By acquiring Vosaic, a University of Illinois-based Internet start-up, in 1999, VTEL has begun to aggressively address the need to adapt its core video-conferencing expertise to this new transmission medium. Second, as an increasingly popular e-commerce infrastructure, the Internet offers unprecedented access to new markets and customers without the need to rely on intermediaries. By expanding its video-conferencing products from hardware - software combination products into pure software solutions that can run on any personal computer, VTEL can also harness the Internet as a distribution and sales channel for its new generation of products without the need for storing and shipping physical hardware. Sales, marketing, and distribution of its products can all occur via the Internet. VTEL's Internet products will be launched in several waves, all relying on the same bandwidth optimizing technology and no-download viewing capabilities. The first wave of products will be aimed at one-way streaming of mostly archived, but in some cases also live visual content. A video-mail type product will thus lead the way with the associated server and hosting infrastructure. This product will be closely followed by a wave of visual applications aimed at several specific OEM opportunities as well as the distance learning market in general. The subsequent wave of products will expand the interactive capabilities of the first thus broadening their market applicability. PRODUCT SUPPORT AND EXPANSION OF SUPPORT CAPABILITIES Currently, end-user support and installation of our products are provided by resellers and VARs, by Dictaphone in the United States, Fujitsu/Bell Atlantic and ICL Sorbus (a wholly-owned subsidiary of Fujitsu/Bell Atlantic) in most foreign markets as third-party service providers or directly by VTEL in order to provide a comprehensive service offering for its worldwide customer base. We train the service employees of Dictaphone, Fujitsu/Bell Atlantic and ICL Sorbus and VTEL's resellers on diagnostics and service of its products. Dictaphone, Fujitsu/Bell Atlantic and ICL Sorbus and the reseller service network are supported by trained technicians at VTEL's Technical Assistance Center. In order to meet all of its service commitments, we currently employ our own field service engineers as well as maintain contracts with third party Certified ISO technicians. COMPETITION The videoconferencing industry is highly competitive. VTEL believes that the principal competitive factors in the industry are product architecture, ease of use, video and audio quality, functionality, service and support, market visibility, and price. We face competition from a number of companies that market communications systems for videoconferencing. Currently in the United States, PictureTel Corporation, Sony Corporation, Nippon Electric Corporation, 9

Polycom Corporation, and Tandberg ASA, among others, are marketing roll-about group videoconferencing systems and multipoint control units. Internationally, videoconferencing systems are available from, among others, British Telecommunications plc., PictureTel Corporation, Sony Corporation, Nippon Electric Corporation, Mitsubishi, Ltd., Fujitsu, Ltd., Panasonic Ltd., Polycom Corporation, and Tandberg ASA. Certain of our competitors have devoted significant resources to the development and marketing of person-to-person visual communications products, such as desktop videoconferencing systems, set-top systems, and software-based internet/intranet visual communications systems, which may help to increase awareness in the value of visual communications products while also resulting in increased competition. Microsoft has introduced visual components to its NetMeeting Release 2.0(TM) product. We intend to continue to focus on large-, small-, and work-group visual communication systems, in addition to gateways and other products, where we believe we can add significant value through software, user interfaces, integrated environments, and applications designed to meet the needs of its targeted markets. Additionally, we recognize that as streaming technology proliferates over the Internet, there will be increased competition directed toward our Internet products. Our competitors and many of our potential competitors are more established, benefit from greater market recognition, and have greater financial, technological, production, and marketing resources than we do. It is possible for these factors to have an adverse impact on our competitive position. MANUFACTURING VTEL's manufacturing operations consist of integration and testing of subsystems and assemblies. Our manufacturing strategy is to contract work to established vendors, with VTEL fulfilling the quality and materials management functions. Substantially all of the integrated circuits, subsystems and assemblies used in our products are made to our specifications by third parties under contract. We establish the relationship with the component vendors, qualifies the vendors and arranges for shipment to VTEL or directly to the vendor responsible for the next level of integration. Systems must pass several levels of testing, including testing with current-release software, prior to shipment. Our manufacturing quality system was initially certified in December 1994 as meeting the standards of ISO 9002 as set by the International Standards Organization. VTEL has passed subsequent audits with only minimal corrective action needed. We rely on outside vendors for supplying substantially all of our electronic components, subsystems and assemblies. Although we use standard parts and components for our products that are generally available from multiple vendors, certain components are currently available only from sole sources and embody such parties' proprietary technology. We depend upon our suppliers to deliver products that are free from defects, competitive in functionality and price and consistent with our specifications and delivery schedules. The failure of a supplier to provide such products could delay or interrupt our manufacture and delivery of products and thereby adversely affect our business and operating results. We endeavor to mitigate the potential adverse effect of supply interruptions by carefully qualifying vendors on the basis of quality and dependability and by maintaining adequate inventories of certain components. However, there can be no assurance that such components will be readily available when needed. Similarly, excessive rework costs associated with defective components or process errors could adversely affect our business and operating results. We do not have contracts with many of our suppliers ensuring continued availability of key components. VTEL attempts to forecast orders and to purchase certain long lead-time components in advance of receipt of purchase orders from customers to enable us to provide timely deliveries to customers when customer orders are received. In addition, from time to time we enter into development arrangements with other third parties to develop and incorporate new features and functions into our products. As such, we are dependent upon these third parties to fulfill their respective obligations under these development arrangements, and failure of these third parties to do so could have a material adverse effect on our results of operations. 10

PATENTS AND TRADEMARKS VTEL has 24 patents issued by the United States Patent and Trademark Office and 15 patent applications pending related to our technology. There can be no assurance that the pending patents will be issued or that issued patents can be defended successfully. However, we do not consider patent protection crucial to our success. We believe that, due to the rapid pace of technological change in the videoconferencing industry, legal protection for our products are less significant than factors such as our use of an open architecture, the success of our distribution strategy, the ongoing product innovation and the knowledge, ability and experience of our employees. VTEL has been issued two trademarks and two service marks by the United States Patent and Trademark Office covering the "VTEL" mark and our logo as well as trademarks and service marks issued by certain foreign countries and entities. Applications for other trademarks are currently pending both in the United States and abroad. EMPLOYEES At July 31, 1999, we employed 617 full-time employees as follows: NUMBER OF FUNCTION EMPLOYEES Sales and marketing 224 Research and development 113 Service, support and systems integration 143 Manufacturing 50 Finance and administration 87 ============= Total 617 ============= Our continued success will depend, in large part, on our ability to attract and retain trained and qualified personnel who are in great demand throughout the industry. None of our employees are represented by a labor union. We believe that our employee relations are good. VTEL's development, management of its growth and other activities de- pend on the efforts of key management and technical employees. Competition for such personnel is intense. We use incentives, including competitive compensation and stock option plans, to attract and retain well-qualified employees. There can be no assurance, however, that we will continue to attract and retain personnel with the requisite capabilities and experience. The loss of one or more of our key management or technical personnel also could have a material and adverse affect. VTEL generally does not have employment agreements with its key management personnel or technical employees. Our future success is also dependent upon our ability to effectively attract, retain, train, motivate and manage our employees. Failure to do so could have a material adverse effect on our business and operating results. EXECUTIVE OFFICERS Our executive officers are as follows: 11

PROPERTIES VTEL's headquarters, product development, and sales and marketing facility leases approximately 139,000 square feet in Austin, Texas under a lease which expires in March 2013. During fiscal 1999, we reduced the workforce of VTEL (see Restructuring Activities in Item 7.) and as a result were able to sublet approximately 15,000 square feet during the later part of fiscal 1999 and the first quarter of fiscal 2000. We believe that the remaining facilities are adequate to meet our current requirements, and that suitable additional space will be available, as needed, to accommodate further physical expansion of corporate and development operations and for additional sales and marketing offices. VTEL occupies approximately 60,000 square feet of a facility that is situated in a light industrial area in Austin, Texas where our manufacturing, training and spare parts depot are located. VTEL's manufacturing facilities and equipment are currently utilized generally on a one-shift per day basis. Should additional manufacturing capacity be needed during the next year, we believe that it could provide the necessary manufacturing capacity through the addition of work shifts or subcontractors and additional warehouse space. VTEL leases 52,500 square feet in Sunnyvale, California under a lease that expires in April 2008. We have a research and development group in our Sunnyvale location. As a result of its restructuring activities, VTEL has sublet approximately 5,200 square feet at its Sunnyvale location. VTEL's Professional Services group occupies a facility of approximately 41,000 square feet in the Philadelphia, Pennsylvania vicinity which is leased through June 2006. ITEM 3. LEGAL PROCEEDINGS VTEL is the defendant or plaintiff in various actions which arose in the normal course of business. In the opinion of management, the ultimate disposition of these matters will not have a material adverse affect on our financial condition or results of operations. Our wholly owned subsidiary, CLI, was previously involved in a legal dispute with Philips Electronics North America Corporation ("Philips"). On May 25, 1999, we announced a compromise settlement agreement between Philips and CLI. The settlement agreement, valued at less than $900,000, stipulates payment by CLI in the form of cash and a future payment under a note, for $250,000 (see Note 8 in the Consolidated Financial Statements), as well as warrants for VTEL common stock. These amounts had previously been accrued as part of the reserve for contingent liabilities related to the merger (see Note 1 in the Consolidated Financial Statements). In addition, the settlement mutually releases each party from all future claims, demands and causes of action. ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS None 13

PART II. ITEM 5. MARKET FOR THE REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS Since April 7, 1992, VTEL's Common Stock has been traded in the NASDAQ-National Market System under the symbol "VTEL". The following table sets forth the range of high and low closing prices for each fiscal quarter of 1997, 1998 and 1999: FISCAL YEAR FISCAL YEAR FISCAL YEAR 1997 1998 1999 HIGH LOW HIGH LOW HIGH LOW 1st Quarter $ 10.625 $ 6.625 $ 8.875 $ 5.438 $ 5.875 $ 2.875 2nd Quarter $ 11.000 $ 8.250 $ 8.438 $ 5.625 $ 4.750 $ 2.500 3rd Quarter $ 8.625 $ 4.875 $ 7.688 $ 5.250 $ 9.250 $ 2.000 4th Quarter $ 7.125 $ 5.500 $ 7.063 $ 4.750 $ 6.500 $ 4.000 VTEL has not paid cash dividends on its Common Stock and presently intends to continue a policy of retaining earnings for reinvestment in its business. ITEM 6. SELECTED FINANCIAL DATA The following table sets forth consolidated financial data for VTEL as of the dates and for the periods indicated. All such data reflects the Merger with CLI on May 23, 1997, which was accounted for as a pooling of interests. The consolidated operations data for the years ended July 31, 1997, 1998 and 1999 has been derived from the audited consolidated financial statements of VTEL included elsewhere herein. The consolidated operations data for the year ended December 31, 1995 and the seven months ended July 31, 1996 has been derived from the audited consolidated financial statements of VTEL not included herein. The consolidated balance sheet data as of July 31, 1998 and 1999 has been derived from the audited consolidated financial statements of VTEL included elsewhere herein. The consolidated balance sheet data as of December 31, 1995 and July 31, 1996 and 1997 have been derived from the audited consolidated financial statements of VTEL not included herein. The consolidated financial data as of July 31, 1995 and for the seven months then ended have been derived from the unaudited consolidated financial statements of VTEL not included herein. The unaudited consolidated financial data include all adjustments, consisting of normal recurring adjustments, which VTEL considers necessary for a fair presentation of its financial position as of such dates and the results of operations and cash flows for such periods. The selected financial data should be read in conjunction with the consolidated financial statements of VTEL and "Management's Discussion and Analysis of Financial Condition and Results of Operations." The Restatement of the Consolidated Financial Information combines the financial information of VTEL and CLI giving retroactive effect to the merger as if the two companies had operated as a single company for all periods presented. However, the two companies operated independently prior to the merger that was consummated in May 1997 and the historical changes and trends in the financial condition and results of operations of these two companies resulted from independent activities. 14

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS OF THE COMPANY On May 23, 1997, shareholders of VTEL and CLI approved the merger of VTEL-Sub, Inc., a Delaware corporation and direct wholly-owned subsidiary of VTEL ("Merger Sub"), with and into CLI, pursuant to an Agreement and Plan of Merger and Reorganization (the "Merger Agreement"), with CLI becoming a direct wholly-owned subsidiary of VTEL (the "Merger"). The restatement of the consolidated financial information for the year ended July 31, 1997 combines the financial information of VTEL and CLI giving retroactive effect to the Merger as if the two companies had operated as a single company for the entire year. The following discussion of the consolidated operations and financial condition of VTEL should be read in conjunction with our consolidated financial statements and related notes thereto included elsewhere herein. The restatement of the consolidated financial information combines the financial information of VTEL and CLI giving retroactive effect to the Merger as if the two companies had operated as a single company for all periods presented. However, the two companies operated independently prior to the Merger that was consummated in May 1997 and the historical changes and trends in the financial condition and results of operations of these two companies resulted from independent activities. Nonetheless, the following Management's Discussion and Analysis of Financial Condition and Results of Operations attempts to relate the activities which resulted in the changes in financial condition and results of operations of the combined company, taking into consideration that a trend or change in the historical results of the combined entity was caused by many events related to each individual company operating independently as competitors. The financial information presented on a historical restated basis is not indicative of the financial condition and results of operations that may have been achieved in the past or will be achieved in the future had the companies operated as a single entity for the periods presented. The following discussion of the consolidated operations and financial condition of VTEL should be read in conjunction with our consolidated financial statements and related notes thereto included elsewhere herein. RESULT OF OPERATIONS The following table sets forth for the fiscal periods indicated the percentage of revenues represented by certain items in VTEL's consolidated statement of operations: 15

FOR THE YEARS ENDED JULY 31, 1997 1998 1999 Revenues 100.0% 100.0% 100.0% Gross margin 39.1 47.3 44.4 Selling, general and administrative 34.2 36.1 40.1 Research and development 12.8 11.1 11.8 Total operating expenses 62.9 46.8 54.7 Other income, net 0.6 1.1 0.1 Net income (loss) from continuing operations (23.2) 1.5 (10.3) Net income (loss) (27.3)% 1.5% (10.3)% FOR THE YEARS ENDED JULY 31, 1997, 1998, AND 1999 Revenues Consolidated revenues decreased from $191.0 million in fiscal 1997 to $179.7 million in fiscal 1998 and to $151.6 million in fiscal 1999. Revenues for the year ended July 31, 1998 decreased in comparison with revenues for the year ended July 31, 1997 due to Merger transition issues. During the year ended July 31, 1998, we combined the sales forces of VTEL and CLI, migrated to a single product platform by eliminating the former CLI platform, and combined the management and operations of the two companies into a single organization. The primary reason for the decrease in revenues during fiscal 1999 was the result of a decrease in unit sales of our large group visual communications systems. The decline in revenues is also attributed to delays or shifts in purchasing decisions of customers resulting from new product announcements by VTEL and its competitors. We have determined that trends presented by our customer base indicate shifts of capital spending. It appears that customers may be delaying their purchase decision for large group systems while they evaluate the impact of converting from videoconferencing systems which currently run on digital (ISDN) type phone lines to systems which run on Internet Protocol (IP) packet based networks. We anticipate that this trend will reverse itself as we release products in fiscal 2000 that provide an IP network solution. We differentiate our operations between product and service. We feel that our service capabilities set us apart from our competitors. Service revenues have continued to increase over the last three fiscal years, and for the years ended July 31, 1997, 1998, and 1999, services have represented 21%, 25% and 30%, respectively, of total revenues. Margins associated with our service operations have continued to increase, for the years ended July 31, 1997, 1998 and 1999, gross margins for services increased to 28%, 36% and 37%, respectively. International sales as a percentage of total consolidated product revenues were, 26%, 24% and 22% for the years ended July 31, 1997, 1998, and 1999. These revenue percentages represent export sales from our domestic operations, as well as sales from our foreign subsidiaries. The general decline in international sales over the three year period can be attributed to many factors including the economic decline in the Far East and competition from foreign producers of competing videoconferencing systems in Europe as well as the Far East. 16

VTEL primarily sells its products through resellers. For the years ended July 31, 1997, 1998 and 1999 reseller sales were 75%, 77% and 80% of product sales, respectively. One of VTEL's initiatives is to grow revenues from non-U.S. markets. Non-U.S. operations are subject to certain risks inherent in conducting business abroad including price and currency exchange fluctuations and restrictive government actions. We believe our foreign currency exposure to be relatively low as foreign sales are predominantly in U.S. dollars. We use currency hedging programs that utilize foreign currency forward contracts on a limited basis and review the credit worthiness of our customers to mitigate foreign currency exchange and credit risk. There can be no assurance that our foreign currency hedging program will effectively hedge foreign currency exchange risk (see also "Market Risk" below). While we strive for consistent revenue growth, there can be no assurance that consistent revenue growth or profitability can be achieved. Consistent with many companies in the technology industry, our business model is characterized by a very high degree of operating leverage. Our expense levels are based, in part, on our expectations as to future revenue levels, which are difficult to predict partly due to VTEL's strategy of distributing its products primarily through resellers. Because expense levels are based on our expectations as to future revenues, our expense base is relatively fixed in the short term. If revenue levels are below expectations, operating results may be materially and adversely affected and net income is likely to be disproportionately adversely affected. In addition, our quarterly and annual results may fluctuate as a result of many factors, including price reductions, delays in the introduction of new products, delays in purchase decisions due to new product announcements by VTEL or its competitors, cancellations or delays of orders, interruptions or delays in supplies of key components, changes in reseller base, customer base, business or product mix and seasonal patterns and other shifts of capital spending by customers. There can be no assurance that we will be able to increase or even maintain our current level of revenues on a quarterly or annual basis in the future. Gross margin Gross margins were 39%, 47% and 44% for the years ended July 31, 1997 ,1998, and 1999 respectively. During the year ended July 31, 1997 VTEL's restated combined revenues consisted of a higher proportion of revenues from CLI, which resulted in a lower gross margin on a combined basis. The higher proportion of product revenues from the large group visual communications systems using the ESA platform resulted in a higher blended gross margin for the year ended July 31, 1998 as compared to the year ended July 31, 1998. The lower gross margin percentage for the year ended July 31, 1999 was the result of the shift by our customers to the purchase of lower margin product segments as well as lower average sales prices brought on by competitive price pressure. Gross product margins were also adversely affected by excess manufacturing capacity as unit sales were lower than initially anticipated. As we continue to grow our Global Services division, the associated service and systems integration revenues which generally carry a lower gross margin than our product revenues, may contribute to overall downward gross margin pressure. While many customers continue to delay the purchase of higher cost large group systems, some are shifting to the purchase of lower cost small group systems in order to maintain their visual communications networks with only a moderate continued investment during the perceived industry transition. We believe this transition will be driven by the shift to visual communications systems which function within an IP network environment. As such, we anticipate that lower gross margins will be offset by stronger unit sales as IP networks proliferate. We expect gross margin pressures due to price competitiveness in the industry, shifts in the product sales mix and anticipated offerings of new products, which may carry a lower gross margin. We expect that overall price competitiveness in the industry will continue to become more intense as users of visual communication systems attempt to balance performance, functionality and cost. Our gross margin is subject to fluctuation based on pricing, production costs and sales mix. 17

Selling, general and administrative Selling, general and administrative expenses of $60.9 million in fiscal 1999 decreased by 6% from $64.8 million in fiscal 1998, which decreased by 1% from $65.4 million in fiscal 1997. Selling, general and administrative expenses were 34%, 36% and 40% of revenues for the years ended July 31, 1997, 1998 and 1999. Selling, general and administrative expenses as a percentage of revenue increased from the year ended July 31, 1997 to the year ended July 31, 1998. The proportionate increase was due to investments made during the year ended July 31, 1998 related to marketing and branding campaigns which were designed to provide brand awareness for VTEL's products and to establish VTEL as an industry leader in visual communications. Additionally, Merger transition issues related to the combination of the sales forces of VTEL and CLI contributed to an increase in selling, general and administrative expenses without a proportionate increase in revenues. Selling, general and administrative expenses as a percentage of revenue increased from the year ended July 31, 1998 to the year ended July 31, 1999 despite a decline in total expenses. VTEL's expense levels were based, in part, on expectations as to revenue levels. Because expense levels were based on our expectations of future revenues, our expense base is relatively fixed in the short term. For this reason, the selling, general and administrative expenses were higher, as a percentage of revenues, for fiscal 1999 as compared to prior periods. Research and development expense Research and development expenses of $18.0 million in fiscal 1999 decreased by 9.5% from $19.9 million in fiscal 1998, which decreased by 18.7% from $24.5 million in 1997. Research and development expenses were 12.8%, 11.1% and 11.8% of revenues for the years ended July 31, 1997, 1998, and 1999. Merger-related expenses recorded during the year ended July 31, 1997 included a $3.2 million charge for the write-off of capitalized research and development cost incurred by CLI for products that were discontinued subsequent to the Merger. Efficiencies were realized by combining the research and development efforts of VTEL and CLI subsequent to the Merger and the Company migrated to a single product platform by eliminating CLI's product platform. The research and development capabilities of both companies were then focused on a single platform such that Company could make a larger investment in its ESA(TM) platform while reducing the overall research and development expenses of the combined companies. Additionally, during the year ended July 31, 1998, we capitalized $0.98 million of software development costs related to new product developments resulting in a reduction in research and development expenses recorded during the year. The decrease in research and development expense from the year ended July 31, 1998 to the year ended July 31, 1999 reflects the capitalization of software development costs totaling $6.4 million. Research and development projects being capitalized are related to the new user interface software included with our next generation of video conferencing systems and software for video conferencing solutions over IP networks. In October 1999, the user interface software was released with our new Galaxy(TM) line of visual communication systems. Software development costs are capitalized after a product is determined to be technologically feasible and is in the process of being developed for market. At the time of release, the capitalized software will be amortized over the estimated economic life of the related projects. During the year ended July 31, 1999, research and development expenses included a charge for in-process research and development related to the acquired assets of Vosaic (see "Acquisition" below). As part of the valuation associated with Vosaic, we recorded a charge to research and development expense of $474,000. The charge is based on our estimate of purchase price associated with research and development on projects that were in-process at the time of acquisition. The charge for research and development that was in-process relates to the next generation video streaming product that was approximately 20% complete at the date of acquisition. The market for VTEL's products is characterized by rapidly changing technology, evolving industry standards and frequent product introductions. New products are generally characterized by increased functionality and better picture quality at lower bandwidths and at reduced prices. The introduction of 18

products, by either VTEL or its competitors, embodying new technology and the emergence of new industry standards may render existing products obsolete and unmarketable. Our ability to successfully develop and introduce on a timely basis new and enhanced products that embody new technology, anticipate and incorporate evolving industry standards and achieve levels of functionality and prices acceptable to the market will be a significant factor in VTEL's ability to grow and to remain competitive. Although the percentage of revenues invested in research and development may vary from period to period, VTEL is committed to investing in its research and development programs. Merger and other expense Merger and other expense decreased from $29.4 million in fiscal 1997 to a $1.5 million credit to income in fiscal 1998 and a $0.2 million credit to income in fiscal 1999. Merger and other expenses of $29.4 million recorded during fiscal 1997 consisted of transaction expenses of $5.7 million and restructuring and other expenses of $23.7 million. See Note 1 to the Consolidated Financial Statements. In connection with the Merger, we made the decision to discontinue the CLI product-line and made the transition to a single product platform, VTEL's Enterprise Series Architecture (ESA) platform. We also made the decision to reduce duplicate operating functions, which resulted in a reduction in the workforce of CLI. The merger transition plan also resulted in a charge in fiscal 1997 for the obsolescence of all the remaining CLI inventory related to the discontinued products ($3.5 million) and the impairment of excess and unproductive assets ($9.0 million). Asset impairment was determined by estimating the lower of the asset's carrying amount or fair value less cost to sell. Management determined that, based on unanticipated favorable events that occurred during fiscal 1998, including resolution of certain litigation and other matters, a reversal of certain accruals totaling $2.6 million should be recorded in fiscal 1998. Separately, a charge of $1.0 million was recorded to reflect the final write-off and disposal costs of remaining discontinued CLI inventory, which had previously been held for sale. During the year ended July 31, 1999, the final significant contingent liabilities, involving litigation in which CLI was a defendant, were either settled or dismissed in court. Final Merger related payments totaling $1.3 million were paid during 1999. In addition, we recorded a note payable to Philips Electronics North America Corporation for $0.3 million as part of terms of that settlement agreement. Since no determinable contingent liabilities remained in relation to the Merger, the final balance of accrued liabilities totaling $0.2 million were returned as a credit to the Consolidated Statement of Operations. Restructuring Activities In November 1998, management adopted a restructuring plan that is intended to match the size and complexity of the organization with our planned path. The plan included the involuntary reduction of 138 employees in 1999. Terminations were generally made in all departments, including manufacturing, sales, management and accounting, and were effective immediately for most employees upon announcement. We also made the decision to reduce operating costs by exiting other activities and reducing related overhead costs. These activities included the closure of certain field sales offices and our Sunnyvale, California spare parts depot. As a result of the restructuring, we recorded a charge of $3.1 million during the year ended July 31, 1999. As of July 31, 1999, substantially all of the termination and severance benefits had been paid. The transition of the spare parts depot in Sunnyvale was completed during 1999. The following schedule summarizes the components and activities of the restructuring plan: BALANCE RESTRUCTURING EXPENDITURES ACCRUED AT CHARGE INCURRED JULY 31, 1999 Termination and severance benefits $ 2,311 $ 2,293 $ 18 Facility closure and other (primarily non-cancelable lease obligations) 769 769 - ------- ------- ---- $ 3,080 $ 3,062 $ 18 ======= ======= ==== 19

Interest income and expense Interest income was $2.7 million, $1.2 million and $.8 million for the years ended July 31, 1997, 1998, and 1999, respectively. Changes in interest income are based on interest rates earned on invested cash and cash balances available for investment. The decrease in interest income during fiscal 1998 is the result of the reduced cash balances due to Merger related expenditures incurred and primarily is the result of reduced cash balances due to operating losses during fiscal 1999. Interest expense was $1.6 million, $0 and $0.9 million for the years July 31, 1997, 1998 and 1999 respectively. Interest expense for the year ending July 31, 1997 relates almost entirely to VTEL's wholly-owned subsidiary, CLI, which relied on lines of credit to fund working capital and capital investment requirements. No interest expense was incurred during fiscal 1998 as we repaid all outstanding debt prior to July 31, 1997. Interest expense during fiscal 1999 relates to borrowings under our line of credit as well as interest paid on notes payable. Income taxes We have experienced substantial changes in ownership as defined by the Internal Revenue Code. These changes result in annual limitations of the amount of net operating loss carryforward generated prior to each change which can be utilized to offset future taxable income. As a result of the ownership change at CLI at the date of the Merger, a portion of CLI's net operating loss carryforward generated prior to the Merger will never be available to offset future taxable income due to the effect of the annual limitation and the expiration of the related net operating losses. Therefore, the unavailable portion of the net operating loss carryforward is not considered in determining the deferred tax asset at July 31, 1999. At July 31, 1999, VTEL had total domestic net operating loss carryforwards of $113,948 ($40,530 and $73,418 for VTEL and CLI, respectively). The portions of these carryforwards available for utilization during fiscal 2000 (in consideration of the annual limitations) are $83,048. Additional net operating losses created prior to the changes in control of $2,574 become available in each subsequent year and accumulate if not used until such net operating losses expire. Due to the uncertainty surrounding the timing of realizing the benefits of our favorable tax attributes in future tax returns, we have placed a full valuation allowance against our net deferred tax asset. Accordingly, no deferred tax benefit has been recorded for the years ended July 31, 1997, 1998 and 1999. Discontinued operation In November 1995, VTEL's wholly-owned subsidiary, CLI, adopted a plan to discontinue operation of its broadcast products division and focus its efforts and resources in developing and marketing videoconferencing products. In June 1996, CLI completed the sale of certain assets of its broadcast products division. During the year ended July 31, 1997, CLI revised the amount of loss associated with disposing of the broadcast products division and recorded an additional charge of $7.8 million, primarily due to additional at-risk receivables that were subsequently identified (see Note 7 to the Consolidated Financial Statements). No activity related to discontinued operation was recorded in either fiscal 1998 or 1999. 20

Net income (loss) VTEL generated a net loss from continuing operations of $44.3 million for the year ended July 31, 1997. In fiscal 1998, we recorded net income from continuing operations of $2.8 million. For the year ended July 31, 1999 we generated a net loss of $15.6 million. The large net loss incurred for the year ended July 31, 1997 was due substantially to charges of $29.4 million taken related to the Merger (see Note 1 to the Consolidated Financial Statements). We generated net income during fiscal 1998 as a result of a reduction of operating expenses which was greater than the decline in revenues and several nonrecurring events. Additionally, we generated income of approximately $1.3 million (net of expenses) from a planned non-recurring real estate transaction which eliminated duplicate corporate headquarter facilities. Due to the favorable resolution of certain Merger-related issues during the year ended July 31, 1998, we were able to record a net credit to income of approximately $1.5 million due to the reversal of certain Merger and other accruals that were recorded as of July 31, 1997. The loss generated during fiscal 1999 was the result of lower revenues due to a decline in the demand for large group video conferencing systems. Since expense levels are based to a large extent on revenue expectations we experienced significant losses during the first and second quarters of the year after which we were able to complete its restructuring (see "Restructuring Activities") and align more closely its expense levels with projected revenue. Other factors affecting results of operations VTEL's future results of operations and financial condition could be impacted by the following factors, among others: trends in the videoconferencing market segment, introduction of new products by competitors, increased competition due to the entrance of other companies into the videoconferencing market segment especially more established companies with greater resources than ours, delay in the introduction of higher performance products, market acceptance of new products introduced by VTEL, price competition, interruption of the supply of low-cost products from third-party manufacturers, changes in general economic conditions in any of the countries in which we do business, adverse legal disputes and delays in purchases relating to federal government procurement. Due to the factors noted above and elsewhere in Management's Discussion and Analysis of Financial Condition and Results of Operations, our past earnings and stock price have been, and future earnings and stock price potentially may be, subject to significant volatility, particularly on a quarterly basis. Past financial performance should not be considered a reliable indicator of future performance and investors are cautioned in using historical trends to anticipate results or trends in future periods. Any shortfall in revenue or earnings from the levels anticipated by securities analysts could have an immediate and significant effect on the trading price of VTEL's Common Stock in any given period. Also, we participate in a highly dynamic industry which often contributes to the volatility of VTEL's Common Stock price. On October 1, 1999, VTEL filed Form 8-K in which we restated our Consolidated Statement of Operations for the quarters ended October 31, 1998, January 31, 1999 and April 30, 1999. The restatements are attributed to non-cash adjustments made to certain depreciation and amortization accounts, inventory accounts, and to the reversal of final acceptance revenues for certain Chinese orders in which final cash payment has not yet been received. The unaudited quarterly financial results are included in Note 15 of the accompanying Consolidated Financial Statements. 21

Further, this Annual Report on Form 10-K contains forward-looking statements, within the meaning of the Private Securities Litigation Reform Act of 1995, that relate to future results or events and are based on our current expectations. There are many factors that affect our business and results of operations, all of which involve risks and uncertainties that could cause actual results to differ materially from those reflected in those forward-looking statements, including the risks discussed above and elsewhere herein. Liquidity and capital resources At July 31, 1999, we had working capital of $28.1 million, including $12.1 million in cash, cash equivalents and short-term investments. Cash used by operating activities was $15.2 million for the year ended July 31, 1997. Cash provided by operating activities was $19.8 million for the year ended July 31, 1998. Cash used by operating activities was $10.7 million for the year ended July 31, 1999. Changes in cash from operating activities are primarily the result of the net losses or income generated and changes in working capital, primarily increases and decreases in accounts receivable, inventories and accounts payable. Cash provided by investing activities was $23.3 million for the year ended July 31, 1997 as compared to cash used in investing activities of $10.6 million for the year ended July 31, 1998. During fiscal 1997, cash provided by investing activities was primarily due to the net sale of investments to finance our operations during the period, which included large cash requirements associated with the Merger. During fiscal 1998 cash used in investing activities was primarily the result of expenditures related to leasehold improvements in Austin and Sunnyvale, the implementation of its Enterprise Resource Planning System, our transaction processing and financial accounting system, and purchases of equipment. During fiscal 1999, we used $4.6 million in investing activities that were spent primarily to complete the acquisition of property and equipment and capitalize the costs associated with the research and development of our next generation of visual communication products. These were partially offset by the net sale and maturity of short-term investments. Cash used by financing activities was $5.1 million for the year ended July, 31 1997 as compared to cash provided by financing activities of $1.5 million for the year ended July 31, 1998 and cash provided by financing activities of $8.0 million for the year ended July 31, 1999. Cash used in financing activities during fiscal 1997 was primarily the result of the purchase of treasury stock by VTEL and the repayment of debt by our wholly-owned subsidiary, CLI, offset by the sale of preferred stock by CLI during the year ended July 31, 1997. Cash provided by financing activities for the year ended July 31, 1998 relates to the issuance of stock under VTEL's stock option and stock purchase plans (see Note 10 to our Consolidated Financial Statements). Cash provided by financing activities for the year ended July 31, 1999 relate to borrowing under our line of credit and is offset by the purchase of treasury stock and payments on notes payable. During fiscal 1997, we purchased 455,200 shares of our Common Stock for approximately $3.7 million. All of the repurchased shares were reissued during fiscal 1997 to fulfill requirements for VTEL's Common Stock. In February 1997, we terminated the stock repurchase program. During fiscal 1999 we initiated a new stock repurchase program and repurchased 526,000 shares of our Common Stock for $2.3 million. The repurchased shares have been used to fulfill requirements for VTEL's stock including stock option exercises or stock issuances under business combination transactions. No additional share repurchases are currently planned, although we are authorized to repurchase up to 1,474,000 additional shares. VTEL has a $20.0 million revolving line of credit with a banking syndi- cate. We have issued a letter of credit totaling $1.2 million under our revolving line of credit as a lease deposit on one of our facilities. At July 31, 1999 we have drawn $11.2 million under the syndicated line of credit. The line of credit is subject to loan covenants that require the maintenance of certain financial ratios. In the event we are unable to maintain these ratios in the future; additional advances under the line of credit may not be available. VTEL's principal sources of liquidity at July 31, 1999 consist of $12.1 million of cash, cash equivalents and short-term investments, amounts available under our revolving line of credit and the ability to generate cash from operations. 22

Legal Matters VTEL is the defendant or plaintiff in various actions which arose in the normal course of business. In the opinion of management, the ultimate disposition of these matters will not have a material adverse affect on our financial condition or results of operations. Our wholly owned subsidiary, CLI, was previously involved in a legal dispute with Philips Electronics North America Corporation ("Philips"). On May 25, 1999, we announced a compromise settlement agreement between Philips and CLI. The settlement agreement, valued at less than $900,000 stipulates payment by CLI in the form of cash and a future payment under a note for $250,000 (see Note 8 in the Consolidated Financial Statements), as well as warrants for VTEL common stock. These amounts had previously been accrued as part of the reserve for contingent liabilities related to the merger (See Note 1 in the Consolidated Financial Statements). In addition, the settlement mutually releases each party from all future claims, demands and causes of action. Impact of Year 2000 Many computer systems may experience problems handling dates beyond the year 1999. Therefore, some computer hardware and software will need to be modified prior to the Year 2000 in order to remain functional. Prior to April 1999, we believed that our products were Year 2000 compliant with minor exceptions due to the incorporation of third party software such as Microsoft Windows(TM) which is Year 2000 compliant with minor exceptions. In April 1999, Microsoft announced that upgrades would be made available that will make Microsoft Windows(TM) Year 2000 compliant. The ability to make Windows(TM) compliant favorably affects VTEL customers who are using older video conferencing systems that run on Windows 95, 98 and NT(TM) software. We believe that all our products being shipped are Year 2000 compliant. Additionally, previous shipments of our current products can be made Year 2000 compliant through software patches or upgrades. While we are not currently aware of any other Year 2000 compliance issues with our products, no assurances can be made that problems will not arise such as customer problems with other software programs, operating systems or hardware that disrupt their use of their products. There can be no assurances that such disruption would not negatively impact costs and revenues in future years. The Enterprise Resource Planning System was acquired in 1998. We have been assured by the vendor of our Enterprise Resource Planning System that the system is Year 2000 compliant. On August 1, 1999, the system began processing transactions in our fiscal year 2000. We began assessing Year 2000 issues and Year 2000 testing of other management information systems during fiscal 1998. We presently believe that with modifications to existing software and conversions to new software, the Year 2000 issue can be mitigated. It is not anticipated that there will be a significant increase in costs as much of the Year 2000 activities will be a continuation of the on-going process to improve all of our systems. We have estimated the total costs of Year 2000 compliance and related contingency planning to be $200,000. We have not accrued any amounts related to the expected costs as we intend to expense Year 2000 costs as they are incurred. We have plans to complete our internal risk assessment of Year 2000 issues and expect to complete our review of significant vendors and key business partners by November 15, 1999. Through the implementation of our Year 2000 compliant Enterprise Resource Planning Software and review of all computer hardware on our premises we are optimistic about our ability to continue to be able to conduct business on January 1, 2000. However, other factors that are beyond our control could potentially have a material effect on future financial results. Specific factors that might cause a material impact include, but are not limited to, electrical power outages that would disrupt operations, failure by third parties to timely convert their systems, and similar uncertainties. In addition, Year 2000 issues may impact our customer's ability to purchase products and therefore materially impact our future revenue stream. To the extent these potential revenue reductions cannot be anticipated and/or we cannot reduce operating expenses correspondingly, then we may experience severe unfavorable financial impact to our net income. We have asked our employees to be available during the transition period into 2000 as an additional measure to address any unexpected Year 2000 issues. Recent Accounting Pronouncements In June 1998, the Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standards (SFAS) No. 133, "Accounting for Derivative Instruments and Hedging Activities." SFAS No. 133 establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts (collectively referred to as derivatives) and for hedging activities. SFAS No. 133 requires the recognition of all derivatives as either assets or liabilities in the statement of financial position and the measurement of those instruments at fair value. We are required to adopt this standard in the first quarter of fiscal 2001. We expect that the adoption of SFAS No. 133 will not have a material impact on our financial position or our results of operations. 23

In April 1998, the American Institute of Certified Public Accountants issued Statement of Position (SoP) No. 98-5, "Reporting on the Costs of Start-up Activities", which provides guidance on the financial reporting of start-up costs and organization costs. It requires costs of start-up activities and organization costs to be expensed as incurred. The SoP is effective for VTEL on August 1, 1999. We estimate that the effect of adopting the SoP to be approximately $0.1 million which will be recorded as a cumulative change in accounting principle as reported in the results of operations during the first quarter of fiscal 2000. ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK We identify our principal market risks as foreign currency exchange rate fluctuations and interest rate risk related to long-term debt obligations. Foreign currency exchange rate fluctuations are mostly related to the settlement of net intercompany receivables due from our foreign subsidiaries. The amount of risk is mitigated by the practice of requiring where possible the repayment of such receivables in U.S. currency. In the normal course of business, we employ established policies and procedures to manage these risks. We use proceeds from debt obligations to support general corporate purposes including capital expenditures and working capital needs. Interest rate exposure is related to borrowings under the $20 million revolving line of credit facility. Interest rate exposure with regard to our investments is minor due to the short term nature of our maturities. Foreign Exchange Risk Our objective in managing our exposure to foreign currency exchange rate fluctuations is to reduce the impact of adverse fluctuations in earnings and cash flows associated with foreign currency exchange rate changes. Accordingly, we utilize forward contracts to hedge our foreign currency exposure on firm commitments. The principal currencies hedged during fiscal year 1999 were the German mark, the Euro and Australian dollar. We monitor our foreign currency exchange exposures to ensure the overall effectiveness of our foreign currency hedge positions. However, there can be no assurance our foreign currency hedging activities will offset the impact of substantial fluctuations in currency exchange rates on our results of operations and financial position. The following are summarized market risks of forward contracts at July 31, 1999 by foreign currencies in which we do business: (Thousands except contract rates) Notional Average Unrealized Settlement Contract Gain Functional Currency Amount Rate (Loss) - ------------------------------- ----------------- -------------- ------------- Euros $ 2,261 1.07 $ (19) Australian Dollars 452 0.65 1 ------- ---- ----- $ 2,713 $ (18) ======= ===== * * *

VTEL CORPORATION NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Amounts in thousands, except share and per share data unless otherwise noted) - -------------------------------------------------------------------------------- 1. THE COMPANY VTEL Corporation ("VTEL" or the "Company") designs, manufactures, markets, services and supports integrated, multi-media visual communication systems which operate over private and switched digital communication networks. VTEL distributes its systems to a domestic and international marketplace through a reseller network and directly to end-user customers. On May 23, 1997, shareholders of VTEL and Compression Labs, Incorporated, a Delaware corporation ("CLI"), approved the merger (the "Merger") of VTEL-Sub, Inc., a Delaware corporation and direct wholly-owned subsidiary of VTEL ("Merger Sub"), with and into CLI, pursuant to an Agreement and Plan of Merger and Reorganization (the "Merger Agreement"), with CLI becoming a direct wholly-owned subsidiary of VTEL. The acquisition was accounted for as a pooling of interests and accordingly, the consolidated financial statements have been restated for the period ended July 31, 1997 to include the accounts of CLI. Revenues, net income (loss) from continuing operations and net income (loss) of the separate companies for the 1997 period were as follows: VTEL CLI TOTAL ----------- ------------- ------------- YEAR ENDED JULY 31, 1997 * Revenues $124,438 $ 66,585 $191,023 Net loss from continuing operations ** 556 (44,827) (44,271) Net loss (508) (51,546) (52,054) * Information for CLI is through the date of the Merger, May 23, 1997. ** Includes loss of $29,397 related to the merger. In connection with the Merger, the Company recorded merger and other expenses of $29,397 during the year ended July 31, 1997 as follows: TRANSACTION EXPENSES: Investment banking fees $ 2,391 Legal and accounting fees 1,600 Other 1,663 ---------- 5,654 ---------- RESTRUCTURING AND OTHER: Asset impairments 12,469 Reserve for contingent liabilities 5,271 Severance and termination benefits 3,457 Other 2,546 ---------- 23,743 ---------- Total $ 29,397 ========== In connection with the Merger in 1997, the Company made the decision to discontinue the CLI product-line and made the transition to a single product platform, VTEL's Enterprise Series Architecture (ESA) platform. The Company also made the decision to reduce duplicate operating functions, which resulted in a reduction in the workforce of CLI. These activities resulted in the obsolescence of all of the remaining CLI inventory related to the discontinued products and the impairment of excess and unproductive assets resulting from the merger transition plan. Asset impairment was determined by estimating the lower of the asset's carrying amount or fair value less cost to sell. 32

VTEL CORPORATION NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Amounts in thousands, except share and per share data unless otherwise noted) - -------------------------------------------------------------------------------- The restructuring activities related to the Merger involved the involuntary termination of approximately 150 employees over the period from May 23, 1997 (the date of the Merger) to November 30, 1997. The major components of the asset impairment recorded at July 31, 1997 are as follows: Write-down of recorded value of discontinued CLI inventory due to discontinuance of the CLI product line $ 3,500 Write-off of capitalized software development costs due to 3,200 discontinuance of the CLI product line Write-off of purchased software deemed redundant as a 1,300 result of the Merger Write-off of unproductive CLI assets (primarily furniture, 2,800 fixtures, equipment and leasehold improvements) due to workforce reduction subsequent to the Merger Reserve for uncollectible receivables related to sales of 1,669 products which were subsequently discontinued and no longer supported ---------- Total $ 12,469 ========== Contingent liabilities of $5.2 million accrued at July 31, 1997 reflect amounts accrued for the discharge of pending and threatened litigation against the Company's wholly-owned subsidiary, CLI, and amounts accrued to discharge known and probable vendor disputes related to CLI. These amounts include management's estimate of the probably costs expected to be incurred to settle, discharge or litigate the matters. Other restructuring charges of $2.5 million include $1.6 million related to the cancellation of purchase commitments that had no future economic benefit to the discontinued CLI product-line and costs associated with the closure of redundant facilities. Changes to accrued merger and other and the reserve for asset impairments during the year ended July 31, 1999 were as follows: BALANCE AT PAID IN DISPOSALS REVERSED BALANCE AT JULY 31, FISCAL IN FISCAL IN FISCAL JULY 31, 1998 1999 1999 1999 1999 ASSET IMPAIRMENTS $ 382 $ - $ 382 $ - $ - ============ =========== ============ ============ ============ ACCRUED MERGER AND OTHER EXPENSES: Reserve for contingent liabilities $ 1,484 $ 1,249 $ - $ 235* $ - Severance and termination benefits 257 257 - - - ------------ ----------- ------------ ------------ ------------ $ 1,741 $ 1,506 $ - $ 235 $ - ============ =========== ============ ============ ============ * During the fiscal year ended July 31, 1999, the remaining litigation claims involving CLI were either dismissed in court or settled with the plaintiff. The remaining reserves for contingent liabilities were credited to income. 33

VTEL CORPORATION NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Amounts in thousands, except share and per share data unless otherwise noted) - -------------------------------------------------------------------------------- 2. SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The consolidated financial statements have been prepared in accordance with generally accepted accounting principles and include the accounts of VTEL's wholly owned subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation. Preparation of the consolidated financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that 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. The more significant estimates made by management include the provision for doubtful accounts receivable, inventory write-downs for potentially excess or obsolete inventory, warranty reserves, the valuation allowance for the gross deferred tax asset, contingency reserves, lives of fixed assets and the amortization period for intangible assets. Actual amounts could differ from the estimates made. Management periodically evaluates estimates used in the preparation of the financial statements for continued reasonableness. Appropriate adjustments, if any, to the estimates used are made prospectively based upon such periodic evaluation. Revenue Recognition Product revenues, recorded net of discounts, are recognized at the time a product is shipped or services are performed and the Company has no significant further obligations to the customer. Customer prepayments are deferred until product shipment has occurred or services have been rendered and there are no significant further obligations to the customer. Service revenues are recognized at the time the services are rendered and the Company has no significant further obligations to the customer. Revenues for extended warranty contracts are recorded over the contract period. The Company records an allowance to reduce sales revenue by an amount which reflects management's estimate of potential future sales returns, exchanges, customer stock rotations or price protection discounts. Warranty Costs The Company generally warrants its products against hardware defects for one year from the date of installation but not to exceed fifteen months from date of shipment. A warranty is provided for software defects for ninety days from the date of installation. The Company provides currently for the estimated costs which may be incurred in the future under the warranty program. Software Development Costs Costs incurred in connection with the development of software products are accounted for in accordance with Statement of Financial Accounting Standards ("SFAS") No. 86, "Accounting for the Costs of Computer Software to Be Sold, Leased or Otherwise Marketed." Costs incurred prior to the establishment of technological feasibility are charged to research and development expense. Amortization of capitalized software begins upon initial product shipment. 34

VTEL CORPORATION NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Amounts in thousands, except share and per share data unless otherwise noted) - -------------------------------------------------------------------------------- Software development costs are amortized (a) over the estimated life of the related product (generally thirty months), using the straight-line method or (b) based on the ratio of current revenues from the related products to total estimated revenues for such products, whichever is greater. The Company capitalized internal software development costs of $1,622, $984 and $6,367 for the years ended July 31, 1997, 1998 and 1999, respectively. Amortization of such costs was $1,827, $50 and zero for the years ended July 31, 1997, 1998 and 1999, respectively. In connection with the Merger, the Company recorded an impairment charge of $3,218 related to capitalized software development costs during the year ended July 31, 1997 due to the elimination of the product line to which the capitalized software development costs related. Cash and Equivalents Cash and equivalents include cash and investments in liquid money market accounts. Short-term Investments Short-term investments are carried at market value, which approximates cost, at the balance sheet date. Short-term investments consist of funds primarily invested in mortgage-backed securities guaranteed by the U.S. government, government securities and commercial paper. Investment securities generally have maturities of less than one year. The Company accounts for investment securities under SFAS No. 115, "Accounting for Certain Investments in Debt and Equity Securities." SFAS No. 115 requires investment securities to be classified as held-to-maturity, trading or available-for-sale based on the characteristics of the securities and the activity in the investment portfolio. At July 31, 1998 and 1999, all investment securities are classified as available-for-sale. No unrealized gains or losses have been recorded as a separate component of equity for the current period or prior year as market values approximate cost due to the short-term nature of the investments. Inventories Inventories are stated at the lower of cost (weighted average cost which approximates the first-in, first-out method) or market. Cost includes the acquisition of purchased components, parts and sub-assemblies, labor and overhead. Property and Equipment Property and equipment is recorded at cost. Internal support equipment is video teleconferencing equipment used internally for purposes such as sales and marketing demonstrations, Company meetings, testing, troubleshooting customer problems, and engineering, and is recorded at manufactured cost. Depreciation and amortization are provided using the straight-line method over the estimated economic lives of the assets, ranging from two to ten years, or over the lease term or life of the improvement of the respective assets, as applicable. Repair and maintenance costs are expensed as incurred. The Company periodically reviews the estimated economic lives of property and equipment and will make adjustments according to the latest information available. In accordance with Statement of Position ("SoP") 98-1, "Accounting for the Costs of Computer Software Developed or Obtained for internal Use," the Company capitalized $0.8 million of internal costs associated with the implementation of the Oracle Enterprise Resource Planning Software System, the Company's management resource planning, transaction processing and financial accounting system, during the year ended July 31, 1998. 35

VTEL CORPORATION NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Amounts in thousands, except share and per share data unless otherwise noted) - -------------------------------------------------------------------------------- Intangible Assets Intangible assets include the goodwill that results from various acquisitions of the Company (see Note 3) as well as other intangibles, including acquired technology. Goodwill is associated with the acquisition of the Company's Global Services unit, Vosaic and its subsidiaries in France and Germany. Amortization periods for the intangibles associated with these acquisitions range from 3 to 15 years. In accordance with Accounting Principles Board Opinion ("APB") No. 17, "Intangible Assets," the Company periodically evaluates the amortization period associated with the acquired intangible assets based upon anticipated periods of future benefit. The Company evaluates factors such as loss of employees with key or unique skills, the Company's ability to continue to successfully utilize the specialized knowledge acquired and other relevant factors which could require revision of the estimate of the amortization period. Appropriate adjustments, if any, to the amortization period will be made prospectively based upon such periodic evaluation. Accumulated amortization of intangibles was $2,554 and $3,817 at July 31, 1998 and 1999. Foreign Currency Translation The financial statements of the Company's foreign subsidiaries are measured using the local currency as the functional currency. Accordingly, assets and liabilities of the subsidiaries are translated at current rates of exchange at the balance sheet date. The resultant gains or losses from translation are included in a separate component of stockholders' equity. Income and expense from the subsidiaries are translated using monthly average exchange rates. Income Taxes The Company accounts for income taxes under SFAS No. 109, "Accounting for Income Taxes," which requires the liability method of accounting for income taxes. Under the liability method, deferred taxes are determined based on the difference between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse. Net Income (Loss) Per Share The Company reports earnings per share under SFAS No. 128, "Earnings Per Share." Under SFAS No. 128, basic earnings per share is based on the weighted effect of all common shares issued and outstanding, and is calculated by dividing net income available to common stockholders by the weighted average shares of common stock outstanding during the period. Diluted earnings per share is calculated by dividing net income available to common stockholders by the weighted average number of common shares used in the basic earnings per share calculation plus the number of common shares that would be issued assuming conversion of all potentially dilutive shares outstanding. All historical earnings per share data have been restated to conform to the current year presentation. The calculation of the number of weighted average shares outstanding for basic and dilutive earnings (loss) per share for each of the periods presented is as follows: FOR THE YEARS ENDED JULY 31, 1997 1998 1999 Weighted average shares Outstanding - basic 22,255 23,057 23,509 ------- ------- ------- Effect of Dilutive Securities: Stock options - 400 - Warrants to purchase common stock - 1 - ------- ------- ------- Dilutive potential common shares - 401 - ------- ------- ------- Weighted average shares outstanding - diluted 22,255 23,458 23,509 ======= ======= ======= Antidilutive securities 3,648 1,764 4,457 ======= ======= ======= 36

Net loss applicable to common stock for the year ended July 31, 1997 is computed by increasing the net loss from continuing operations by $2,527 which represents a deemed dividend related to the 20% conversion discount on Series C Preferred Stock measured at the date of original issuance. Concentration of Credit Risk The Company sells its products to various companies across several industries, including third-party resellers. The Company performs ongoing credit evaluations of its customers and maintains reserves for potential credit losses. The Company requires advanced payments or secured transactions when deemed necessary. Fair Value of Financial Instruments The carrying amount of the Company's financial instruments, including cash and equivalents, short-term investments and short-term trade receivables, payables, and debt, approximates fair value. The fair value of the Company's foreign currency forward contracts is determined at July 31, 1998 and 1999 based on quoted market rates. The carrying amount of short-term investments approximates fair value because of the short maturity and nature of these instruments. The Company places its cash in investment quality financial instruments and limits the amount invested in any one institution or in any type of instrument. The Company has not experienced any significant losses on its investments. Long-lived Assets The Company evaluates its long-lived assets and intangibles based on guidance provided by SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of." SFAS No. 121 established accounting standards for the impairment of long-lived assets, certain identifiable intangibles, and goodwill related to those assets to be held and used for long-lived assets and certain identifiable intangibles to be disposed of. The Company believes no impairment exists at July 31, 1999. Employee Stock Plans The Company determines the fair value of grants of stock, stock options and other equity instruments issued to employees in accordance with SFAS No. 123, "Accounting and Disclosure of Stock-Based Compensation." SFAS No. 123 encourages, but does not require, companies to recognize compensation expense for grants of stock, stock options, and other equity instruments to employees based on their estimated fair market value on the date of grant. The Company has opted to continue to apply the existing accounting rules contained in APB No. 25, "Accounting for Stock Issued to Employees." As such, SFAS No. 123 has had no effect on the Company's financial position or results of operations. The Company records unearned compensation related to stock options that are issued at exercise prices which are below the fair market value of the underlying stock on the measurement date. Such unearned compensation is amortized ratably over the vesting period of the related stock options. Treasury Stock The Company accounts for its treasury stock purchases and issuances using the cost method. 37

VTEL CORPORATION NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Amounts in thousands, except share and per share data unless otherwise noted) - -------------------------------------------------------------------------------- Comprehensive Income During fiscal 1999, the Company adopted SFAS No. 130, "Reporting Comprehensive Income." SFAS No.130 establishes standards for reporting comprehensive income and its components. The Company's comprehensive income (loss) is shown on the Company's Statement of Changes in Stockholders' Equity and is comprised of net income (loss) and foreign currency translation adjustments. Segment Information The Company adopted SFAS No. 131, "Disclosures about Segments of an Enterprise and Related Information," in the fiscal year ended July 31, 1999. SFAS No. 131 supersedes SFAS No. 14, "Financial Reporting for Segments of a Business Enterprise," replacing the "industry segment" approach with the "management" approach. The management approach designates the internal organization that is used by management for making operating decisions and assessing performance as the source of the Company's reportable segments. SFAS No. 131 also requires disclosures about products and services, geographic areas and major customers. The adoption of SFAS No. 131 did not affect the Company's results of operations or financial position, but did affect the disclosure of segment information as and has been used for all years presented in these financial statements (Note 14). Recent Accounting Pronouncements In June 1998, Financial Accounting Standards Board (FASB) issued SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities." SFAS No. 133 establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts (collectively referred to as derivatives) and for hedging activities. SFAS No. 133 requires the recognition of all derivatives as either assets or liabilities in the statement of financial position and the measurement of those instruments at fair value. The Company is required to adopt this standard in the first quarter of fiscal 2001. The Company expects that the adoption of SFAS No. 133 will not have a material impact on it financial position or its results of operations. In April 1998, American Institute of Certified Public Accountants issued SoP No. 98-5, "Reporting on the Costs of Start-up Activities", which provides guidance on the financial reporting of start-up costs and organization costs. It requires costs of start-up activities and organization costs to be expensed as incurred. The SoP is effective for the Company on August 1, 1999. The Company estimates that the effect of adopting the SoP to be approximately $100 which will be recorded as a cumulative change in accounting principle in the results of operations during the first quarter of fiscal 2000. 3. ACQUISITIONS The Company consummated the acquisition of certain of the assets of the videoconferencing division of one of its German resellers effective July 1, 1998. The consideration paid by the Company consisted of restricted stock, warrants, a note payable, and the assumption of certain payables and other liabilities totaling approximately $1,871. During fiscal 1999, the Company completed the acquisition of one of its French resellers primarily through the issuance of restricted stock for approximately $826.

RESTRUCTURING ACTIVITIES In November 1998, management adopted a restructuring plan that was intended to match the size and complexity of the organization with the planned path of the Company. The plan included the involuntary reduction of 138 employees in fiscal 1999. Terminations were generally made in all departments, including manufacturing, sales, management and accounting, and were effective immediately for most employees upon announcement. The Company also made the decision to reduce operating costs by exiting other activities and reducing related overhead costs. These activities included the closure of certain field sales offices and its Sunnyvale, California spare parts depot. As a result of the restructuring, the Company recorded a charge of $3.1 million during the year ended July 31, 1999. As of July 31, 1999, substantially all of the termination and severance benefits had been paid. The transition of the spare parts depot in Sunnyvale was completed during 1999. The following schedule summarizes the components and activities of the restructuring plan: BALANCE RESTRUCTURING EXPENDITURES ACCRUED AT EXPENSE INCURRED JULY 31, 1999 Termination and severance benefits $ 2,311 $ 2,293 $ 18 Facility closure and other (primarily non-cancelable lease obligations) 769 769 - -------- -------- ------ $ 3,080 $ 3,062 $ 18 ======== ======== ====== 7. DISCONTINUED OPERATION On June 27, 1996, CLI completed the sale of certain assets of its broadcast products division to another company in exchange for $12,500 in cash and the assumption of $2,000 in liabilities. The purchaser assumed past warranty obligations associated with the product family covered by the sale. With the exception of the accounts receivable, CLI disposed of the remaining assets of the division to a separate buyer. During the year ended July 31, 1997, the Company recorded a provision for probable losses to fully reserve the remaining accounts receivable of the discontinued operation that were considered to be uncollectible. Such provision is reflected in the accompanying consolidated statement of operations in the net loss from discontinued operations. No revenues from discontinued operation were recorded during the years ended July 31, 1997, 1998 or 1999. 40

LINE OF CREDIT On May 5, 1999, the Company executed a credit agreement with a banking syndicate which established a $20,000 revolving line of credit. Under the line of credit, the Company may borrow up to 80% of eligible accounts receivable. The credit agreement also provides that the Company may request the issuance of letters of credit up to a maximum of $10,000 and foreign exchange contracts up to a maximum of $10,000. Each of the aforementioned provisions are subject to certain limitations. Any amounts outstanding under the credit agreement will bear interest at the prime rate plus 0.5% (8.5 % at July 31, 1999) or, at the option of the Company, LIBOR plus 3.25% (9.05% at July 31, 1999) The interest rates may decline if the Company achieves consecutive profitable quarters. All such advances and accrued interest under the credit agreement will be payable on the maturity date of May 4, 2001. The Company pays an annual commitment fee of 0.375% on its unused line of credit. 41

VTEL CORPORATION NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Amounts in thousands, except share and per share data unless otherwise noted) - -------------------------------------------------------------------------------- Any amounts outstanding under the credit agreement will be secured by substantially all of the Company's assets. The credit agreement requires that the Company maintain certain financial ratios and other covenants. The Company has issued a letter of credit totaling $1,200 under the line of credit as a lease deposit on one of its facilities. At July 31, 1999, the Company had drawn $11,200 under the credit line. 10. STOCKHOLDERS' EQUITY General In May 1997, VTEL issued 155,040 shares of Common Stock, at the fair market value, to Intel in lieu of repayment of the remaining $901 advance under the Development Agreement (see Note 11) that was unused at that time. On March 9, 1999, the Company completed the acquisition of substantially all of the assets of Vosaic LLP, an Internet video software and technology company which involved the issuance of 1,149,000. Of these shares, 200,000 are to be held in escrow and an additional 350,000 warrants remain unearned pending the completion of certain obligations by Vosaic (see Note 3). Share Repurchase Program During fiscal 1997, the Company purchased 455,200 shares of its Common Stock for approximately $3.7 million. All of the repurchased shares were reissued during fiscal 1997 to fulfill requirements for the Company's Common Stock. In February 1997, the Company terminated the stock repurchase program. During fiscal 1999, the Company initiated a new stock repurchase program and repurchased 526,000 shares of its Common Stock for $2.3 million. The repurchased shares have been be used to fulfill requirements for the Company's stock including stock option exercises or stock issuances under business combination transactions. No additional share repurchases are currently planned, although the Company is authorized to repurchase up to 1,474,000 additional shares. Stock Subscriptions Receivable During fiscal 1999, the Company loaned certain employees of the Company amounts to either purchase shares of the Company's stock on the open market, exercise options or participate in the employee stock purchase program. Receivables with recourse totaling $150 that are related to the exercise of options and the participation of the employee stock purchase program have been classified as a reduction of additional paid-in capital. Receivables with recourse totaling $750 related to the purchase of shares on the open market have been classified as other long-term assets. CLI Redeemable Convertible Preferred Stock On October 25, 1996, CLI completed a private placement of 350,000 shares of Class C Preferred Stock and stock warrants for the purchase of 375,000 shares of CLI Common Stock for approximately $7,000, before certain issuance costs, pursuant to a purchase agreement with an institutional investor. The preferred stock was exchanged for 1,102,500 shares of VTEL Common Stock and both the number and exercise price of the warrants were converted into warrants for the purchase of VTEL Common Stock based on the exchange ratio of 0.46 in connection with the Merger. The converted warrants, totaling 172,500 VTEL shares, have an exercise price of $12.39 and expire in October 2001. Stock and Stock Option Plans VTEL has three stock option plans, the 1989 Stock Option Plan (the "1989 Plan"), the 1996 Stock Option Plan (the "1996 Plan") and the 1992 Director Stock Option Plan (the "1992 Plan"). The 1989 Plan and the 1996 Plan both provide for the issuance of non-qualified and incentive stock options to employees and consultants of the Company. Stock options are generally granted at 42

VTEL CORPORATION NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Amounts in thousands, except share and per share data unless otherwise noted) - -------------------------------------------------------------------------------- the fair market value at the time of grant, and the options generally vest ratably over 48 months and are generally exercisable for a period of ten years beginning with date of grant. The 1992 Plan provides for the issuance of stock options to nonemployee directors at the fair market value at the time of grant. Effective June 1999, the 1989 Plan expired whereby the company can no longer grant options under the Plan, however, options previously granted remain outstanding. Such options vest ratably over 36 months and are exercisable for a period of ten years beginning with the date of the grant. CLI had employee and director stock option plans prior to the merger with VTEL. On May 23, 1997, all options outstanding under these plans were converted into options for Common Stock of VTEL. Both the number of shares subject to option and the per share exercise price under each option were adjusted by the exchange ratio of 0.46. The Company applies APB No. 25 and related interpretations in accounting for its stock option plans. Accordingly, no compensation cost is recognized for its stock option plans unless options are issued at exercise prices which are below the market price on the measurement date. Had compensation cost for the Company's stock option plans been determined based on the fair market value at the grant dates for awards under those plans consistent with the method provided by SFAS No. 123, the Company's net loss and net loss per share would have been reflected by the following pro forma amounts for the years ended July 31, 1997, 1998 and 1999: FOR THE YEARS ENDED JULY 31, 1997 1998 1999 Net income (loss) As reported $ (52,054) $ 2,779 $ (15,565) Pro forma $ (55,276) $(1,589) $ (20,023) Basic and diluted net income (loss) per common share As reported $ (2.45) $ 0.12 $ (0.66) Pro forma $ (2.60) $ (0.07) $ (0.85) The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions used for grants the years ended July 31, 1997, 1998 and 1999: FOR THE YEARS ENDED JULY 31, 1997 1998 1999 Dividend yield - - - Expected volatility 92.31% 63.12% 67.67% Risk-free rate of return 5.90% 5.52% 6.14% Expected life 5.12 years 5.65 years 6.26 years 43

However, stock issued upon exercise of a stock option is subject to repurchase by the Company at the exercise price until the option vesting period has elapsed. At July 31, 1999, options to purchase 2,140,615 shares were vested. At July 31, 1999, 30,540 unvested options had been exercised. Employee Stock Purchase Plan On April 29, 1993, VTEL adopted an Employee Stock Purchase Plan ("Employee Plan") which enables all employees to acquire VTEL stock under the plan. The Employee Plan authorizes the issuance of up to 950,000 shares of VTEL's Common Stock. The Employee Plan allows participants to purchase shares of the Company's Common Stock at a price equal to the lesser of (a) 85% of the fair market value of the Common Stock on the date of the grant of the option or (b) 85% of the fair market value of the Common Stock at the time of exercise. Common Stock issued under the Employee Plan totaled 105,549 shares, 158,073 shares and 203,118 shares respectively, for the years ended July 31, 1997, 1998 and 1999. 44

The 1998 Plan authorizes the issuance of up to 1,000,000 shares of VTEL's Common Stock.to be used to reward, incent and retain its employees. Shares of restricted stock issued under the 1998 Plan were 80,000 for the year ended July 31, 1999. 11. DEVELOPMENT AND LICENSE AGREEMENT On October 22, 1993, VTEL entered into a Development and License Agreement (the "Development Agreement") with Intel Corporation ("Intel"), pursuant to which the companies agreed to engage in a series of development efforts with respect to video compression software as well as other video technology such as processes and designs. The agreement contains certain provisions for licensing agreements and royalties between the two companies for the use of the technology developed under the agreement. The initial term of the Development Agreement has renewed until December 31, 1999 and will continue to automatically renew thereafter for successive terms of one year unless written notice is given by either party six months prior to the expiration of the initial term or any successor term. VTEL was advanced $3,000 under the agreement to be used for the initial reimbursements of research and development costs incurred by VTEL in performing the work specified in the Development Agreement. During the year ended July 31, 1997, the Company reduced gross research and development expenses by approximately $5 for reimbursable research and development costs under the terms of the Development Agreement. No reductions of research and development expenses were recorded during the years ended July 31, 1998 and 1999 as a result of the Development Agreement. In May 1997, VTEL issued 155,040 shares of Common Stock, at the fair market value, to Intel in lieu of repayment of the remaining $901 advance that was unused at that time. As of July 31, 1999, the Company had no research and development activities in process or planned related to the Development Agreement. 45

FEDERAL INCOME TAXES Under the provisions of SFAS No. 109, the components of the net deferred tax amount are as follows: JULY 31, 1998 1999 DEFERRED TAX ASSETS: Net operating loss carryforwards $ 29,140 $ 38,742 Research and development credit carryforwards 3,458 4,379 Minimum tax credit carryforwards 110 110 Inventory and warranty provisions 1,246 1,921 Charitable contributions 22 40 Compensation accruals 635 306 Depreciation 630 - Deferred revenue 1,796 713 Accrued expenses 841 - Accounts receivable 3,163 292 Other 558 545 ---------- ---------- Gross deferred tax asset 41,599 47,048 ---------- ---------- DEFERRED TAX LIABILITIES: Capitalized software (274) (220) Depreciation - (453) ---------- ---------- Gross deferred tax liability (274) (673) ---------- ---------- Valuation allowance (41,325) (46,375) ---------- ---------- Net deferred tax asset $ - $ - ========== ========== The Company's net operating loss carryforwards expire in varying amounts from 1999 through 2019. Research and development tax credit carryforwards expire in varying amounts from 1999 through 2019. Minimum tax credit carryforwards do not expire and carry forward indefinitely. Net operating losses related to the Company's foreign subsidiaries (totaling $ 7,222) are available to offset future foreign taxable income. The Company has experienced substantial changes in ownership as defined by the Internal Revenue Code. These changes result in annual limitations of the amount of net operating loss carryforward generated prior to each change which can be utilized to offset future taxable income. As a result of the ownership change at CLI at the date of the Merger, a portion of CLI's net operating loss carryforward generated prior to the Merger will never be available to offset future taxable income due to the effect of the annual limitation and the expiration of the related net operating losses. At July 31, 1999, the Company had total domestic net operating loss carryforwards of $113,948 ($40,530 and $73,418 for VTEL and CLI, respectively). The portions of these carryforwards available for utilization during fiscal 2000 (in consideration of the annual limitations) are $83,048. Additional net operating losses created prior to the changes in control of $2,574 become available in each subsequent year and accumulate if not used until such net operating losses expire. Due to the uncertainty surrounding the timing of realizing the bene- its of its favorable tax attributes in future tax returns, the Company has placed a valuation allowance against its net deferred tax asset. Accordingly, no deferred tax benefits have been recorded for the years ended July 31, 1997, 1998, and 1999. 13. COMMITMENTS AND CONTINGENCIES Lease Commitments VTEL leases furniture and equipment, manufacturing facilities and office space under noncancelable leases which expire at various dates through 2013. Certain leases obligate VTEL to pay property taxes, maintenance and repair costs. 46

VTEL CORPORATION NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Amounts in thousands, except share and per share data unless otherwise noted) - -------------------------------------------------------------------------------- Future minimum lease payments under all operating leases as of July 31, 1999 were as follows: FISCAL YEAR ENDING: 2000 $ 7,289 2001 7,115 2002 6,647 2003 5,830 2004 5,435 Thereafter 32,380 ----------- $ 64,696 =========== Total rent expense under all operating leases for the years ended July 31, 1997, 1998 and 1999 was $4,601, $4,301 and $4,520 respectively. During the year ended July 31, 1998, the Company completed the planned elimination of duplicate headquarter facilities by terminating the lease for the former CLI headquarters. The landlord paid the Company a $1,800 termination fee which is recorded (net of termination expenses) as Other Income in the accompanying Statement of Operations. In connection with the acquisition of certain of the assets of the videoconferencing division of one of its German resellers, (see Note 3), the Company entered into a five year licensing agreement pursuant to which the Company will pay a license fee equal to 4% of the revenues generated by the acquired assets with a minimum annual fee of $281 to $393 and a maximum annual fee of $786. Contingencies The Company is the defendant or plaintiff in various actions which arose in the normal course of business. In the opinion of management, the ultimate disposition of these matters will not have a material adverse affect on our financial condition, results of operation or cash flows. The Company was previously involved in a legal dispute with Philips Electronics North America Corporation ("Philips"). On May 25, 1999, the Company announced a compromise settlement agreement between Philips and CLI. The settlement agreement, valued at less than $900, stipulates payment by CLI in the form of cash and a future payment under a note of $250 (See Note 8), as well as warrants for VTEL common stock. These amounts had previously been accrued as part of the reserve for contingent liabilities related to the merger (See Note 1). In addition, the settlement mutually releases each party from all future claims, demands and causes of action. 14. SEGMENT INFORMATION In 1999, the company adopted SFAS 131. The Company manages its business primarily on a products and services basis. The Company's reportable segments are Products and Services/Other. The Products segment provides multi-media visual communication (commonly referred to as videoteleconferencing) products to customers primarily through a network of resellers, and to a lesser extent directly to end-users. The Services/Other segment provides custom integrated systems, installations and product support services to customers. The accounting policies of the segments are the same as those described in Note 2. The Company evaluates the performance of its segments and allocates resources to them based on revenue and operating income; however, there is a charge to allocate corporate operating expenses to the segments. The prior year's segment information has been restated to present the Company's reportable segments. The table below presents segment information about revenue from unaffiliated customers, depreciation and operating income for the three years ended July 31, 1999: 47

Such Issuing Lender shall give telephonic or facsimile notice to the Lenders of the receipt and amount of any draft presented under any Letter of Credit and the date on which payment thereon will be made, and each of the Lenders shall, by 2:00 p.m. Central Time on the date such payment is to be made under such Letter of Credit, pay to such Issuing Lender in immediately available funds, an amount equal to the product of (A) such Lender's Commitment Percentage times (B) the amount of such payment to be made by the Issuing Lender to the beneficiary under such Letter of Credit.

reimburse each Lender for any and all fees, costs and expenses relating thereto or arising in connection therewith. (c) Borrower shall not permit the total gross amount of all Exchange Contracts on which delivery is to be effected and settlement allowed on any one (1) Business Day to be more than Two Million and No/100 Dollars ($2,000,000.00) ("Settlement Limit") nor shall Borrower permit the total gross amount of all Exchange Contracts to which Borrower is a party, outstanding at any one time, to exceed the lesser of the (i) Contract Limit and (ii) lesser of (A) the Committed Revolving Line minus all outstanding Credit Extensions and (B) the Borrowing Base minus all outstanding Credit Extensions. Notwithstanding the above, however, the amount which may be settled on any one (1) Business Day may be increased above the Settlement Limit up to, but in no event to exceed, the amount of the Contract Limit under either of the following circumstances: (i) if there is sufficient availability under the Committed Revolving Line in the amount of the Foreign Exchange Reserve as of each Determination Date, provided that Servicing Agent and Lenders in advance shall reserve the full amount of the Foreign Exchange Reserve against the Committed Revolving Line; or (ii) if there is insufficient availability under the Committed Revolving Line, as to settlements on any one (1) Business Day, provided that Servicing Agent and Lenders, in their sole discretion, may: (A) verify good funds overseas prior to crediting Borrower's deposit account with the applicable Lender (in the case of Borrower's sale of foreign currency); or (B) debit Borrower's deposit account with the applicable Lender prior to delivering foreign currency overseas (in the case of Borrower's purchase of foreign currency). (d) In the case of Borrower's purchase of foreign currency, Borrower in advance shall instruct Servicing Agent or the applicable Lender upon settlement either to treat the settlement amount as an Advance under the Committed Revolving Line, or to debit Borrower's account for the amount settled. (e) Borrower shall execute all standard form applications and agreements of the applicable Lender in connection with the Exchange Contracts and, without limiting any of the terms of such applications and agreements, Borrower will pay all standard fees and charges of the applicable Lender in connection with the Exchange Contracts. (f) WITHOUT LIMITING ANY OF THE OTHER TERMS OF THIS AGREEMENT OR ANY SUCH STANDARD FORM APPLICATIONS AND AGREEMENT OF LENDERS OR SERVICING AGENT, BORROWER AGREES TO INDEMNIFY LENDERS AND SERVICING AGENT AND HOLD THEM HARMLESS, FROM AND AGAINST ANY AND ALL CLAIMS, DEBTS, LIABILITIES, DEMANDS, OBLIGATIONS, ACTIONS, COSTS AND EXPENSES (INCLUDING, WITHOUT LIMITATION, ATTORNEYS' FEES OF COUNSEL OF LENDERS' CHOICE), OF EVERY NATURE AND DESCRIPTION WHICH IT MAY SUSTAIN OR INCUR, BASED UPON, ARISING OUT OF, OR IN ANY WAY RELATING TO ANY OF THE EXCHANGE CONTRACTS OR ANY TRANSACTIONS RELATING THERETO OR CONTEMPLATED THEREBY OTHER THAN SUCH LOSSES, COSTS, EXPENSES OR LIABILITIES BASED 15

UPON OR ARISING OUT OF THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE SERVICING AGENT OR SUCH LENDER. (g) Simultaneously with any Lender's entering into with Borrower any Exchange Contract ("Applicable Lender"), such Applicable Lender shall be deemed, without further action, to have sold to each other Lender, and each such other Lender shall be deemed, without further action by any party hereto, to have purchased from such Applicable Lender, participation interest (which participation shall be nonrecourse to such Applicable Lender) equal to such other Lender's Commitment Percentage at such time in such Exchange Contract and all of the Obligations related to such Exchange Contract; provided, that no such Lender shall be obligated to participate in a particular Exchange Contract if such Exchange Contract was issued or honored solely as a result of such Applicable Lender's gross negligence or willful misconduct. Each Lender acknowledges and agrees that its obligation to acquire participations in each Exchange Contract, as well as its obligation to make the payments specified in this Section 2.1.3 and the right of such Applicable Lender to receive the same in the manner specified herein, are absolute and unconditional and shall not be affected by any circumstances whatsoever, including without limitation, the occurrence and continuance of an Event of Default hereunder, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. (h) The Applicable Lender with respect to any Exchange Contract shall review, on behalf of the Lenders, all documents presented under such Exchange Contract. Promptly after it shall have ascertained that all accompanying documents presented under such Exchange Contract appear on their face to be in conformity with the terms and conditions of such Exchange Contract, such Applicable Lender shall effect delivery or allow settlement thereof. Such Applicable Lender shall give telephonic or facsimile notice to the Lenders of the amount and the date on which delivery is to be effected or settlement allowed, and each of the Lenders shall, by 2:00 p.m. Central Time on the date such delivery is to be effected or settlement allowed under such Exchange Contract, pay in immediately available funds, an amount equal to the product of (A) such Lender's Commitment Percentage times (B) the amount of such payment to be made by the Applicable Lender under such Exchange Contract. Any Lender failing to timely deliver its requisite portion of any such payment shall deliver the same to the Applicable Lender as soon as possible thereafter, together with interest on such amount for each day from the due date for such payment to the date of payment by such Lender to the Applicable Lender of such amount at a rate of interest per annum equal to the Federal Funds Effective Rate for such period. Each Lender hereby absolutely and unconditionally assumes, as primary obligor and not as a surety, and agrees to pay and discharge, and to indemnify and hold the Applicable Lender harmless from liability and respect of, such Lender's pro rata share (based on such Lender's Commitment Percentage) of any amounts owing by such Lender to the Applicable Lender in accordance with the immediately preceding sentence. 2.2 Overadvances. If, at any time or for any reason, the amount of Obligations owed by Borrower pursuant to Section 2.1.1, 2.1.2 and 2.1.3 of this Agreement is greater than the lesser of (i) the Committed Revolving Line and (ii) the Borrowing Base, Borrower shall immediately pay to Servicing Agent, in cash, for the ratable benefit of Lenders, the amount of such excess. 16

2.3 Interest Rates, Payments, and Calculations. (a) LIBOR Option/Interest Rate. Except as set forth in Section 2.3(b), any and all Advances shall bear interest, on the average daily balance thereof, at a per annum rate equal to, at Borrower's option and subject to the terms hereof, the Prime Rate plus one-half percent (0.5%) or the rate specified in the LIBOR Supplement. (b) Default Rate. All Obligations shall bear interest, from and after the occurrence, and during the continuance, of an Event of Default, at the "Default Interest Rate." The Default Interest Rate shall be the interest rate applicable immediately prior to the occurrence of the Event of Default plus five (5) percentage points but in no event more than the Maximum Lawful Rate or at a rate that would cause the total interest contracted for, charged or received by any Lender to exceed the Maximum Lawful Amount. (c) Payments. Interest hereunder shall be due and payable on each Payment Date. Any interest not paid when due shall be compounded by becoming a part of the Obligations, and such interest shall thereafter accrue interest at the rate then applicable hereunder. (d) Computation. (i) Changes. In the event the Prime Rate is changed from time to time hereafter, the applicable rate of interest hereunder shall be increased or decreased effective as of 12:01 a.m. on the day the Prime Rate is changed, by an amount equal to such change in the Prime Rate. (ii) Spreading of Interest. Because of the possibility of irregular periodic balances of principal, the fluctuating nature of the interest rate, or premature payment, the total interest that will accrue under this Agreement cannot be determined in advance. Lenders do not intend to contract for, charge or receive more than the Maximum Lawful Rate or Maximum Lawful Amount permitted by applicable state or federal law, and to prevent such an occurrence Lenders and Servicing Agent and Borrower agree that all amounts of interest, whenever contracted for, charged or received by Lenders or Servicing Agent, with respect to the loan of money evidenced by the Loan Documents, shall be spread, prorated or allocated over the full period of time the Obligations are unpaid, including the period of any renewal or extension thereof. If the maturity of the Obligations is accelerated for any reason whether as a result of a lawsuit or an Event of Default or otherwise prior to the full stated term, the total amount of interest contracted for, charged or received to the time of such demand shall be spread, prorated or allocated along with any interest thereafter accruing over the full period of time that the Obligations thereafter remain unpaid for the purpose of determining if such interest exceeds the Maximum Lawful Amount. (iii) Excess Interest. At maturity (whether by acceleration or otherwise) or on earlier final payment of the Obligations, each Lender shall compute the total amount of interest that has been contracted for, charged or received by such Lender or payable by Borrower hereunder to such Lender and compare such amount to the Maximum Lawful Amount that could have been contracted for, charged or received by such Lender. If such computation reflects that the total amount of interest that has been contracted for, charged or received by such Lender or payable by Borrower to such Lender exceeds the Maximum Lawful Amount, then such Lender shall apply such excess to the reduction of the principal balance owing to it and not to the payment of interest; 17

or if such excess interest exceeds the unpaid principal balance owing to such Lender, such excess shall be refunded to Borrower. This provision concerning the crediting or refund of excess interest shall control and take precedence over all other agreements between Borrower and Lenders so that under no circumstances shall the total interest contracted for, charged or received by any Lender exceed the Maximum Lawful Amount. (iv) Daily Computation of Interest. To the extent permitted by applicable law, the Lenders at their option may either (i) calculate the per diem interest rate or amount based on the actual number of days in the year (365 or 366, as the case may be), and charge that per diem interest rate or amount each day, or (ii) calculate the per diem interest rate or amount as if each year has only 360 days, and charge that per diem interest rate or amount each day for the actual number of days of the year (365 or 366 as the case may be). If the Loan Documents call for monthly payments, the Lenders at their option may determine the payment amount based on the assumption that each year has only 360 days and each month has 30 days. In no event shall Lenders compute the interest in a manner that would cause Lenders to contract for, charge or receive interest that would exceed the Maximum Lawful Rate or the Maximum Lawful Amount. The foregoing notwithstanding, all Lenders shall calculate per diem interest in the same manner at all times, and in no event shall the method of daily computation of interest vary between or among any of the Lenders. (v) Revolving Loan Accounts and Usury Ceiling. In no event shall Chapter 346 of the Texas Finance Code, as supplemented by the Texas Credit Code ("Texas Finance Code") (which regulates certain revolving loan accounts and revolving tri-party accounts) apply to this Agreement or Borrower's payment obligations hereunder. To the extent that Chapter 303 of the Texas Finance Code, is applicable to this Agreement, the "weekly ceiling" specified in such Chapter 303 is the applicable ceiling; provided that, if any applicable law permits greater interest, the law permitting the greatest interest shall apply. (e) Borrowing Procedures. (i) Whenever Borrower desires an Advance, Borrower will notify Servicing Agent by facsimile transmission or telephone no later than 1:00 p.m. Central time, one (1) Business Day before the Business Day on which a Prime Rate Advance is to be made and 2:00 p.m. Central Time on the Business Day that is three (3) Business Days prior to the Business Day a LIBOR rate Advance is to be made. Servicing Agent shall promptly deliver such notice to the Lenders, and each Lender shall make its applicable Advance available on the proposed date thereof by paying such amount in immediately available funds not later than 2:00 p.m. Central Time to Servicing Agent. Any Lender failing to timely deliver its requisite portion of any such payment shall deliver the same to Servicing Agent as soon as possible thereafter, together with interest on such amount for each day from the due date for such payment to the date of payment by such Lender to Servicing Agent of such amount at a rate of interest per annum equal to the Federal Funds Effective Rate for such period. Each such notification by Borrower shall be promptly confirmed by a Payment/Advance Form in substantially the form of Exhibit B hereto or a LIBOR rate Advance Form as attached to the LIBOR Supplement. Servicing Agent is authorized to make Advances under this Agreement or under the LIBOR Supplement, based upon instructions received from a Responsible Officer or a designee of a Responsible Officer, or without instructions if in Servicing Agent's discretion such Advances are necessary to meet Obligations which have become due and remain unpaid. Servicing Agent and 18

Lenders shall be entitled to rely on any telephonic notice given by a person whom Servicing Agent or Lenders reasonably believe to be a Responsible Officer or a designee thereof, and BORROWER SHALL INDEMNIFY AND HOLD SERVICING AGENT AND THE LENDERS HARMLESS FROM AND AGAINST ANY DAMAGES OR LOSS SUFFERED BY SERVICING AGENT OR EITHER LENDER AS A RESULT OF SUCH RELIANCE OTHER THAN SUCH LOSSES, COSTS, EXPENSES OR LIABILITIES BASED UPON OR ARISING OUT OF THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE SERVICING AGENT OR SUCH LENDER. (ii) Whenever Borrower desires the issuance of a Letter of Credit, Borrower will notify the applicable Issuing Lender (and the Servicing Agent, if the Servicing Agent is not the applicable Issuing Lender) by facsimile transmission no later than 1:00 p.m. Central time, five (5) Business Days before the Business Day on which the Letter of Credit is to be issued. The applicable Issuing Lender shall promptly deliver such notice to the other Lenders and shall promptly confirm to the other Lenders the actual issuance of such requested Letter of Credit once issued. 2.4 Crediting Payments. Prior to the occurrence of an Event of Default, Servicing Agent shall credit a wire transfer of funds, check or other item of payment paid by Borrower to Servicing Agent, when received, to such deposit account or Obligation as Borrower specifies. After the occurrence, and during the continuance, of an Event of Default, the receipt by Servicing Agent of any wire transfer of funds, check, or other item of payment, whether directed to Borrower's deposit account with Servicing Agent or to the Obligations or otherwise, shall be immediately applied to conditionally reduce Obligations, but shall not be considered a payment in respect of the Obligations unless such payment is of immediately available federal funds or unless and until such check or other item of payment is honored when presented for payment. Notwithstanding anything to the contrary contained herein, any wire transfer or payment received by Servicing Agent after 2:00 p.m. Central time shall be deemed to have been received by Servicing Agent as of the opening of business on the immediately following Business Day. Whenever any payment to Servicing Agent under the Loan Documents would otherwise be due (except by reason of acceleration) on a date that is not a Business Day, such payment shall instead be due on the next Business Day, and additional fees or interest, as the case may be, shall accrue and be payable for the period of such extension. 2.5 Fees. Borrower shall pay to Servicing Agent the following: (a) Facility Fee. (i) A facility fee equal to One Hundred Thousand and No/100 Dollars ($100,000.00) which fee shall be fully earned and non-refundable and which shall be payable to Servicing Agent, for the pro rata benefit of the Lenders based on their respective Commitment Percentage, in four equal quarterly installments of Twenty-Five Thousand and No/100 Dollars ($25,000.00) beginning on the date hereof and on August 5, 1999, November 5, 1999 and May 5, 2000. (ii) On the last day of each February, May, August and November during the term through the Revolving Maturity Date, as well as on the Revolving Maturity Date, a fee equal to .375% of the Committed Revolving Line (based on actual days elapsed in a 360 day year) minus the average daily balance of all outstanding Advances for the preceding fiscal quarter (i.e., Borrower's 19

quarters ending in January, April, July, and October); provided the amount of such fee shall be decreased by One Thousand One Hundred Twenty-Five and No/100 Dollars ($1,125.00) for the fiscal quarter ending April 30, 1999, July 31, 1999 and October 31, 1999 to properly reflect Borrower's current credit with SVB of Three Thousand Three Hundred Seventy-Five and No/100 Dollars ($3,375.00). Servicing Agent shall apportion the foregoing fees pro rata between Lenders based upon their respective Commitment Percentages, and SVB's portion of such fees shall be reduced by One Thousand One Hundred Twenty-Five and No/100 Dollars ($1,125.00) for the above described fiscal quarters to account for SVB's prior receipt of the foregoing monies from Borrower and to insure that each Lender receives it full .375% fee based on its respective Commitment Percentage. (b) Financial Examination and Appraisal Fees. If an Event of Default has occurred and is continuing, Borrower shall pay each Lender's customary fees and out-of-pocket expenses for Lenders' audits of Borrower's Accounts, and for each appraisal of Collateral and financial analysis and examination of Borrower performed from time to time by Servicing Agent or its agents or any Lender; provided, however, that the fees for the Lenders' audits of Borrower's Accounts prior to the occurrence of an Event of Default shall not exceed Two Thousand and No/100 Dollars ($2,000.00) per annum without the prior approval of Borrower. Provided further, if no Event of Default exists, (i) all such audits conducted by Lenders at Borrower's expense shall be performed by one (1) audit team and shall not be conducted more often than once each calendar year, and (ii) all such other audits conducted by Servicing Agent or any Lender at the expense and cost of Servicing Agent or such Lender, as applicable, shall not be conducted more often than eleven (11) times during any calendar year. Any verification of any of Borrower's Accounts sent to any account debtor of Borrower while no Event of Default has occurred which is then continuing shall be on a form which is reasonably acceptable to Borrower and the Servicing Agent or the applicable Lender. (c) Lenders' Expenses. Upon demand from Servicing Agent, including, without limitation, upon the date hereof, all Lenders' Expenses incurred through the date hereof, including reasonable attorneys' fees and expenses (with respect to audit fees, such fees shall be subject to the limitation set forth in Section 2.5(b) above), and, after the date hereof, all Lenders' Expenses, including reasonable attorneys' fees and expenses, as and when they become due. 2.6 Additional Costs. In case any law, regulation, treaty or official directive or the interpretation or application thereof by any court or any governmental authority charged with the administration thereof or the compliance with any guideline or request of any central bank or other governmental authority (whether or not having the force of law): (a) subjects Servicing Agent or any Lender to any tax with respect to payments of principal or interest or any other amounts payable hereunder by Borrower or otherwise with respect to the transactions contemplated hereby (except for taxes on the overall net income of Servicing Agent or such Lender imposed by the United States of America or any political subdivision thereof); (b) imposes, modifies or deems applicable any deposit insurance, reserve, special deposit, capital adequacy or similar requirement against assets held by, or deposits in or for the account of, or loans by, Servicing Agent or any Lender; or 20

(c) imposes upon Servicing Agent or any Lender any other condition with respect to its performance under this Agreement, and the result of any of the foregoing is to increase the cost to Servicing Agent or such Lender, reduce the income receivable by or rate of return on capital of Servicing Agent or such Lender or impose any expense upon Servicing Agent or such Lender with respect to the Obligations, Servicing Agent or such Lender shall notify Borrower thereof. Borrower agrees to pay to Servicing Agent or such Lender the amount of such increase in cost, reduction in income or rate of return on capital or additional expense as and when such cost, reduction or expense is incurred or determined, upon presentation by Servicing Agent or such Lender of a statement of the amount and setting forth Servicing Agent's or such Lender's calculation thereof, all in reasonable detail, provided, however, that notwithstanding anything herein to the contrary, (a) Borrower shall not be the only borrower of such Lender subject to this type of provision which is requested to pay such amounts for the applicable period and (b) Borrower shall not be liable for any such costs incurred by such Lender more than one hundred eighty (180) days prior to the date of the applicable notice given hereunder. 2.7 Term. Except as otherwise set forth herein, this Agreement shall become effective on the Closing Date and, subject to Section 14.6, shall continue in full force and effect for a term ending on the Revolving Maturity Date. Notwithstanding the foregoing, pursuant to and subject to Section 9.1 below, Lenders shall have the right to terminate their obligation to make Credit Extensions under this Agreement immediately upon the occurrence and during the continuance of an Event of Default with notice thereof to Borrower; provided however, if the Event of Default is an Insolvency Default, then the obligation to make Credit Extensions shall automatically terminate without notice of any kind. Notwithstanding termination of this Agreement, Servicing Agent's Lien on the Collateral shall remain in effect for so long as any Obligations are outstanding. Borrower shall have the right to terminate this Agreement without premium or penalty with notice to Servicing Agent if there are no outstanding Obligations, which Obligations shall include, without limitation, and for purposes of clarification, all four installment payments of the facility fee set forth in Section 2.5(a)(i) above, owing to Servicing Agent or any Lender. 2.8 Pro Rata Treatment. (a) Except to the extent otherwise provided herein, (i) each Credit Extension from the Lenders hereunder shall be made and each payment of Obligations shall be made and applied for the account of the Lenders, and each termination or reduction of the Commitments of the Lenders shall be applied, pro rata, according to each Lender's Commitment Percentage; (ii) each payment or prepayment by the Borrower of principal of or interest on Advances shall be made to the Servicing Agent for the account of the Lenders pro rata in accordance with the respective unpaid principal amounts of such Advances held by the Lenders; (iii) the Lenders (other than the Issuing Lender) shall purchase from the applicable Issuing Lender participations in the Letters of Credit, to the extent of their respective Commitment Percentage, upon issuance by an Issuing Lender of each Letter of Credit as otherwise provided for herein; and (iv) the Lenders (other than the Applicable Lender) shall purchase from the Applicable Lender participations in the applicable Exchange Contracts entered into by such Applicable Lender, to the extent of their respective Commitment Percentage, upon such Applicable Lender entering into an Exchange Contract as otherwise provided for herein. 21

(b) Unless the Servicing Agent shall have been notified in writing by any Lender prior to the date of a proposed Advance that such Lender will not make the amount that would constitute such Lender's Commitment Percentage of such Advance on such date available to the Servicing Agent, the Servicing Agent may assume that such Lender has made such amount available to the Servicing Agent on such date, and the Servicing Agent may, in reliance upon such assumption and subject to the terms and conditions of this Agreement, make such amount available to the Borrower. Any Lender failing to timely deliver its requisite portion of such Advance shall deliver the same to the Servicing Agent as soon as possible thereafter, together with interest on such amount for each day from the due date for such payment to the date of payment by such Lender to the Servicing Agent of such amount at a rate of interest per annum equal to the Federal Funds Effective Rate for such period. In addition, the Borrower hereby agrees that upon demand by the Servicing Agent, the Borrower shall reimburse the Servicing Agent for any such amount which any Lender has failed to timely deliver to the Servicing Agent, but which the Servicing Agent may have previously made available to the Borrower in accordance with the other provisions of this Section 2.8(b). If a requested Advance shall not occur on any date specified by the Borrower as set forth in the Payment/Advance Form because all of the conditions for such Advance set forth herein or in any of the other Loan Documents shall have not been met, the Servicing Agent shall return the amounts so received from the Lenders in respect of such requested Advance to the applicable Lenders as soon as practicable. 2.9 Sharing of Payments, etc. Borrower agrees that, in addition to (and without limitation of) any right of set-off, bankers' lien or counterclaim a Lender may otherwise have, each Lender shall be entitled after the occurrence of an Event of Default which is continuing, at its option, to offset balances held by it for the account of the Borrower at any of its offices against any principal of or interest on any of such Lender's Obligations of the Borrower hereunder which is not paid when due (regardless of whether such balances are then due to the Borrower), in which case it shall promptly notify the Borrower and the Servicing Agent thereof, provided, that such Lender's failure to give such notice shall not affect the validity thereof. If a Lender shall obtain payment of any principal of or interest on any Obligation then due to such Lender hereunder, through the exercise of any right of set-off, banker's lien, counterclaim or similar right, or otherwise, it shall promptly purchase from the other Lenders participations in Obligations of the Borrower hereunder of the other Lenders in such amounts, and make such other adjustments from time to time as shall be equitable to the end that all the Lenders shall share the benefit of such payment (net of any expenses which may be incurred by such Lender in obtaining or preserving such benefit) pro rata in accordance with their respective Commitment Percentage. To such end, all the Lenders shall make appropriate adjustments among themselves (by the resale of participations sold or otherwise) if such payment is rescinded or must otherwise be restored. Borrower agrees, to the fullest extent it may effectively do so under applicable law, that any Lender so purchasing a participation in the Obligations hereunder of the other Lenders may exercise all rights of set-off, bankers' lien, counterclaim or similar rights with respect to such participation as fully as if such Lender were a direct holder of said Obligations in the amount of such participation. Nothing contained herein shall require any Lender to exercise any such right or shall affect the right of any Lender to exercise, and retain the benefits of exercising, any such right with respect to any other indebtedness or obligation of Borrower. 22

3. CONDITIONS OF LOANS 3.1 Conditions Precedent to Initial Credit Extension. The obligation of Lenders to make the initial Credit Extension is subject to the condition precedent that Lenders shall have received, in form and substance satisfactory to Lenders, the following: (a) this Agreement and the Revolving Notes, all duly executed by Borrower; (b) a certificate of the Secretary of Borrower with respect to certificate of incorporation, by-laws, incumbency and resolutions authorizing the execution and delivery of this Agreement and all other Loan Documents to be executed by Borrower; (c) evidence reasonably necessary to confirm a first priority perfected Lien (subject only to Permitted Liens) has been granted by Borrower in favor of Servicing Agent for the benefit of Lenders against all Collateral, including, without limitation, UCC-1 financing statements covering the Collateral and in favor of Servicing Agent on behalf of and for the benefit of Lenders and UCC-3 termination statements or assignments in favor of Servicing Agent on behalf of and for the benefit of the Lenders from each Person that has a security interest in the Collateral or any part thereof; (d) insurance certificate; (e) payment of the fees and Lenders' Expenses then due specified in Section 2.5 hereof; (f) Certificate of Foreign Qualification (if applicable); (g) the Amended and Restated LIBOR Supplement; (h) an intellectual property security agreement covering the Intellectual Property; and (i) such other documents, and completion of such other matters, as Lenders may reasonably deem necessary or appropriate. 3.2 Conditions Precedent to all Credit Extensions. The obligation of Lenders to make each Credit Extension, including the initial Credit Extension, is further subject to the following conditions: (a) timely receipt by Servicing Agent of the Payment/Advance Form or the LIBOR rate Advance Form as provided in Section 2.1, if applicable; (b) satisfaction of the terms and conditions contained in the LIBOR Supplement, if applicable; (c) the representations and warranties contained in Section 5 shall be true and correct in all material respects on and as of the date of such Payment/Advance Form or the 23

LIBOR rate Advance Form and on the effective date of each Credit Extension as though made at and as of each such date, and no Event of Default shall have occurred and be continuing, or would result from such Credit Extension; and (d) receipt by Servicing Agent of a subordination of lien from each and every Person who leases real property to Borrower and at which location Borrower now or hereafter maintains Inventory with a value of Two Million Five Hundred Thousand and No/100 Dollars ($2,500,000.00) or greater (but in any event at Borrower's locations in Austin, Texas and King of Prussia, Pennsylvania), or evidence satisfactory to Servicing Agent and Lenders in their sole and absolute discretion of the waiver of such landlord's liens from such Person or Persons. The making of each Credit Extension shall be deemed to be a representation and warranty by Borrower on the date of such Credit Extension as to the accuracy of the facts referred to in Section 3.2(c). 4. CREATION OF SECURITY INTEREST 4.1 Grant of Security Interest. Borrower grants and pledges to Servicing Agent on behalf of and for the benefit of Lenders a continuing security interest in all presently existing and hereafter acquired or arising Collateral and all proceeds thereof, in order to secure prompt payment of any and all Obligations and in order to secure prompt performance by Borrower of each of its covenants and duties under the Loan Documents. Except as set forth in the Schedule, such security interest constitutes a valid, first priority security interest in the presently existing Collateral, and will constitute a valid, first priority security interest in Collateral acquired after the date hereof. Notwithstanding termination of this Agreement, Servicing Agent's Lien on the Collateral shall remain in effect for so long as any Obligations are outstanding. 4.2 Delivery of Additional Documentation Required. Borrower shall from time to time execute and deliver to Servicing Agent, at the request of Servicing Agent or any Lender, all Negotiable Collateral, all financing statements and other documents that Servicing Agent or any Lender may reasonably request, in form reasonably satisfactory to Requisite Lenders, to perfect and continue perfected Servicing Agent's security interests in the Collateral and in order to fully consummate all of the transactions contemplated under the Loan Documents. 4.3 Right to Inspect. Subject to the provisions of Section 2.5(b), including without limitation, any limitation with respect to the number of inspections or audits prior to the occurrence and continuance of an Event of Default, any Lender (through any of its officers, employees, or agents) shall have the right, upon reasonable prior notice (except that such prior notice shall not be required upon the occurrence and during the continuance of an Event of Default), from time to time during Borrower's usual business hours, so long as Borrower's normal business operations are not unreasonably disrupted, to inspect Borrower's Books and to make copies thereof and to check, test, audit and appraise the Collateral in order to verify Borrower's financial condition or the amount, condition of, or any other matter relating to, the Collateral, including Borrower's Accounts. 24

4.4 Single Loan. All of the Obligations of Borrower to Servicing Agent or Lenders arising under or in connection with this Agreement, or any of the Loan Documents, shall constitute one general obligation of Borrower and shall be secured by all of the Collateral. 5. REPRESENTATIONS AND WARRANTIES Borrower represents and warrants as follows: 5.1 Due Organization and Qualification. Borrower and each Subsidiary of Borrower is a corporation duly existing and in good standing under the laws of its state of incorporation and qualified and licensed to do business in, and is in good standing in, any state in which the conduct of its business or its ownership of property requires that it be so qualified, except for states as to which failure to so qualify would not have a Material Adverse Effect. 5.2 Due Authorization; No Conflict. The execution, delivery, and performance of the Loan Documents are within Borrower's powers, have been duly authorized, and are not in conflict with nor constitute a breach of any provision contained in Borrower's Certificate of Incorporation or By-laws, nor will they constitute an event of default under any material agreement to which Borrower is a party or by which Borrower is bound. Borrower is not in default under any agreement to which it is a party or by which it is bound, which default could have a Material Adverse Effect. 5.3 No Prior Encumbrances. Borrower has good and indefeasible title to the Collateral, free and clear of Liens, except for Permitted Liens. Except as disclosed in the Schedule, Borrower has not acquired any part of the Collateral from an assignor outside the ordinary course of such assignor's business. 5.4 Bona Fide Eligible Accounts. The Eligible Accounts are bona fide existing obligations. The service or property giving rise to such Eligible Accounts has been performed or delivered to the account debtor or to the account debtor's agent for immediate shipment to and unconditional acceptance by the account debtor. Borrower has not received notice of actual or imminent Insolvency Proceeding of any account debtor whose Accounts are included in any Borrowing Base Certificate as an Eligible Account. 5.5 Merchantable Inventory. All Inventory is in all material respects of good and marketable quality, free from all material defects. 5.6 Name; Location of Chief Executive Office. Except as disclosed in the Schedule, Borrower has not done business and will not without at least thirty (30) days prior written notice to Servicing Agent do business under any name other than that specified on the signature page hereof or in the Schedule. The chief executive office of Borrower is located at the address indicated in Section 10 hereof. 5.7 Litigation. Except as set forth in the Schedule, there are no actions or proceedings pending, or, to Borrower's knowledge, threatened by or against Borrower or any 25

Subsidiary of Borrower before any court or administrative agency in which an adverse decision could result in damages or costs to Borrower of One Million and No/100 Dollars ($1,000,000.00) or more or have a Material Adverse Effect. 5.8 No Material Adverse Change in Financial Statements. All consolidated financial statements related to Borrower and any Subsidiary of Borrower that have been delivered by Borrower to Servicing Agent or any Lender fairly present in all material respects Borrower's consolidated financial condition as of the date thereof and Borrower's consolidated results of operations for the period then ended. There has not been a material adverse change in the consolidated financial condition of Borrower since the date of the most recent of such financial statements submitted to Lenders or Servicing Agent on or about the Closing Date. 5.9 Solvency. Borrower is solvent and able to pay its debts (including trade debts) as they mature. 5.10 Regulatory Compliance. Borrower and each Subsidiary of Borrower has met the minimum funding requirements of ERISA with respect to any employee benefit plans subject to ERISA. No event has occurred resulting from Borrower's or any of its Subsidiary's failure to comply with ERISA that is reasonably likely to result in Borrower's or any such Subsidiary's incurring any liability that could have a Material Adverse Effect. Borrower is not an "investment company" or a company "controlled" by an "investment company" within the meaning of the Investment Company Act of 1940. Borrower is not engaged principally, or as one of its important activities, in the business of extending credit for the purpose of purchasing or carrying margin stock (within the meaning of Regulations G, T and U of the Board of Governors of the Federal Reserve System). Borrower and each of its Subsidiaries have complied with all the provisions of the Federal Fair Labor Standards Act, the noncompliance with which would cause a Material Adverse Effect. Neither Borrower nor any of its Subsidiaries has violated any statutes, laws, ordinances or rules applicable to it, violation of which could have a Material Adverse Effect. 5.11 Environmental Condition. None of Borrower's or any of its Subsidiary's properties or assets has ever been used by Borrower or any such Subsidiary or, to the best of Borrower's knowledge, by previous owners or operators, in the disposal of, or to produce, store, handle, treat, release, or transport, any hazardous waste or hazardous substance other than in accordance with applicable law; to the best of Borrower's knowledge, none of Borrower's nor any of its Subsidiary's properties or assets has ever been designated or identified in any manner pursuant to any environmental protection statute as a hazardous waste or hazardous substance disposal site, or a candidate for closure pursuant to any environmental protection statute; no lien, resulting in a Material Adverse Effect, arising under any environmental protection statute has attached to any revenues or to any real or personal property owned by Borrower or any Subsidiary of Borrower; and neither Borrower nor any of its Subsidiaries has received a summons, citation, notice, or directive from the Environmental Protection Agency or any other federal, state or other governmental agency concerning any action or omission by Borrower or any Subsidiary of Borrower resulting in the release, or other disposition of hazardous waste or hazardous substances into the environment. 5.12 Taxes. Borrower and each Subsidiary of Borrower has filed or caused to be filed all tax returns required to be filed on a timely basis except where failure to do so would not 26

reasonably be expected to result in a Material Adverse Effect, and has paid, or has made adequate provision for the payment of, all taxes reflected therein in accordance with GAAP. 5.13 Subsidiaries. Borrower does not own any stock, partnership interest or other equity securities of any Person, except for Permitted Investments. 5.14 Government Consents. Borrower and each Subsidiary of Borrower has obtained all consents, approvals and authorizations of, made all declarations or filings with, and given all notices to, all governmental authorities that are necessary for the continued operation of Borrower's and each such Subsidiary's business as currently conducted, the failure of which to obtain would have a Material Adverse Effect on Borrower's financial condition, operations or business. 5.15 Full Disclosure. No representation, warranty or other statement made by Borrower in any certificate or written statement furnished to Servicing Agent or any Lender contains any untrue statement of a fact or omits to state a fact necessary in order to make the statements contained in such certificates or statements not misleading, except which would not result in a Material Adverse Effect. 5.16 Intellectual Property. Borrower is the sole owner of the Intellectual Property Collateral, except for non-exclusive licenses granted by Borrower to its customers in the ordinary course of business. To the best of Borrower's knowledge, each of the Patents is valid and enforceable, and no part of the Intellectual Property Collateral has been judged invalid or unenforceable, in whole or in part, and no claim has been made that any part of the Intellectual Property Collateral violates the rights of any third party other than as disclosed on the Schedule. Except for and upon the filing with the United States Patent and Trademark Office with respect to the Patents and Trademarks and the Register of Copyrights with respect to the Copyrights and Mask Works necessary to perfect the security interests created hereunder and under the Intellectual Property Security Agreement of even date herewith, and except as has been already made or obtained, no authorization, approval or other action by, and no notice to or filing with, any United States governmental authority or United States regulatory body is required either (i) for the grant by Borrower of the security interest granted hereby and in the Loan Documents or for the execution, delivery or performance of Loan Documents by Borrower in the United States or (ii) for the perfection in the United States or the exercise by Servicing Agent and Lenders of their rights and remedies hereunder. 5.17 No Subordinated Debt. No Subordinate Debt is outstanding hereunder, nor has any Subordinated Debt been previously approved by Required Lenders, as of the date hereof. 5.18 Year 2000 Reprogramming. Any reprogramming required to permit the proper functioning in and following the year 2000, of the Borrower's and its Subsidiaries' material (a) computer systems and (b) equipment containing embedded microchips (including systems and equipment supplied by others or with which the Borrower's or any of its Subsidiaries' systems interface), the failure of which to have completed could reasonably be expected to result in a Material Adverse Effect, and the testing of all such systems and equipment as so reprogrammed, will be substantially completed by September 30, 1999. The cost to the Borrower and its Subsidiaries of such reprogramming and testing of the reasonably foreseeable consequences of year 2000 to the 27

Borrower and its Subsidiaries (including, without limitation, reprogramming errors and the failure of others' systems or equipment) will not result in an Event of Default or a Material Adverse Effect. Except for such of the reprogramming referred to in the preceding sentence as may be necessary, the computer and management information systems of the Borrower and its Subsidiaries are and, with ordinary course upgrading and maintenance, will continue to be, sufficient to permit the Borrower and its Subsidiaries to conduct its business without any Material Adverse Effect. 6. AFFIRMATIVE COVENANTS Borrower covenants and agrees that, until payment in full of all outstanding Obligations, and for so long as Lenders may have any Commitment to make a Credit Extension hereunder, Borrower shall do all of the following: 6.1 Good Standing. Borrower shall maintain its and each of its Subsidiaries' corporate existence and good standing in its jurisdiction of incorporation and maintain qualification in each jurisdiction in which the failure to so qualify could have a Material Adverse Effect. Borrower shall maintain, and shall cause each of its Subsidiaries to maintain in force, to the extent consistent with prudent management of Borrower's business, all licenses, approvals and agreements, the loss of which could have a Material Adverse Effect. Notwithstanding the foregoing, (a) Borrower may dissolve a Subsidiary of Borrower so long as the assets of the Subsidiary remain with Borrower or a wholly-owned Subsidiary of Borrower; and (b) any wholly-owned Subsidiary of Borrower may merge or consolidate with another wholly-owned Subsidiary of Borrower; and (c) any wholly-owned Subsidiary of Borrower may merge or consolidate with Borrower so long as Borrower is the surviving corporation. 6.2 Government Compliance.

Within twenty (20) days after the last day of each month, Borrower shall deliver to Servicing Agent and each Lender then holding not less than one-third of the total Commitments of the Lenders a Borrowing Base Certificate signed by a Responsible Officer in substantially the form of Exhibit C hereto, together with aged listings of accounts receivable and accounts payable and, with the monthly financial statements, a Compliance Certificate signed by a Responsible Officer in substantially the form of Exhibit D hereto. 6.4 Inventory; Returns.

Borrower shall make, and shall cause each Subsidiary of Borrower to make, due and timely payment or deposit of all material federal, state, and local taxes, assessments, or contributions required of it by law, and will execute and deliver to Servicing Agent, on demand if an Event of Default has occurred and is continuing, appropriate certificates attesting to the payment or deposit thereof (provided that Borrower shall confirm such payment in connection with any compliance certificates regularly submitted hereunder); and Borrower will make, and will cause each Subsidiary of Borrower to make, timely payment or deposit of all material tax payments and withholding taxes required of it by applicable laws, including, but not limited to, those laws concerning F.I.C.A., F.U.T.A., state disability, and local, state, and federal income taxes, and will, upon request if an Event of Default has occurred and is continuing, furnish Servicing Agent with proof satisfactory to Servicing Agent and Lenders indicating that Borrower and Subsidiary of Borrower has made such payments or deposits; provided that Borrower or a Subsidiary of Borrower need not make any payment if the amount or validity of such payment does not result in a Material Adverse Effect or is (i) contested in good faith by appropriate proceedings and (ii) is reserved against (to the extent required by GAAP) by Borrower. 29

6.6 Insurance. (a) Borrower, at its expense, shall keep the Collateral insured against loss or damage by fire, theft, explosion, sprinklers, and all other hazards and risks, and in such amounts, as ordinarily insured against by other owners in similar businesses conducted in the locations where Borrower's business is conducted on the date hereof. Borrower shall also maintain insurance relating to Borrower's ownership and use of the Collateral in amounts and of a type that are customary to businesses similar to Borrower's. (b) All such policies of insurance shall be in such form, with such companies, and in such amounts as are reasonably satisfactory to Servicing Agent and Requisite Lenders.

Borrower shall maintain, as of the last day of the fiscal quarter ending April 30, 1999 and the fiscal quarter ending July 31, 1999, a ratio of Quick Assets to Current Liabilities, less the then current portion of deferred maintenance revenue, of at least 1.30 to 1.0. Borrower shall maintain, as of the last day of the fiscal quarter ending October 31, 1999, a ratio of Quick Assets to Current Liabilities, less the then current portion of deferred maintenance revenue, of at least 1.40 to 1.0.

If any material portion of Borrower's assets is attached, seized, subjected to a writ or distress warrant, or is levied upon, or comes into the possession of any trustee, receiver or person acting in a similar capacity and such attachment, seizure, writ or distress warrant or levy has not been removed, discharged or rescinded within thirty (30) days, or if Borrower is enjoined, restrained, or in any way prevented by court order from continuing to conduct all or any material part of its business affairs, or if a judgment or other claim becomes a lien or encumbrance upon any material portion of Borrower's assets, or if a notice of lien, levy, or assessment is filed of record with respect to any of Borrower's assets by the United States Government, or any department, agency, or instrumentality thereof, or by any state, county, municipal, or governmental agency, and the same is not paid within thirty (30) days after Borrower receives notice thereof, provided that none of the foregoing shall constitute an Event of Default where such action or event is stayed or an adequate bond has been posted pending a good faith contest by Borrower (provided that no Credit Extensions will be required to be made during such cure period). 8.5 Insolvency. If an Insolvency Proceeding is commenced by Borrower or if an Insolvency Proceeding is commenced against Borrower (in either case, an "Insolvency Default") and such Insolvency Proceeding commenced against Borrower is not dismissed or stayed within forty-five (45) days (provided that no Advances or Credit Extensions will be made prior to the dismissal of such Insolvency Proceeding). 8.6 Other Agreements. If there is a default in any agreement to which Borrower is a party with a third party or parties resulting in a right by such third party or parties, whether or not exercised, to accelerate the maturity of any Indebtedness in an amount in excess of One Million and No/100 Dollars ($1,000,000) or that could have a Material Adverse Effect. 8.7 Subordinated Debt.

Any of the following shall occur: (1) a Reportable Event shall have occurred with respect to a Plan; (2) the filing by the Borrower, any ERISA Affiliate, or an administrator of any Plan of a notice of intent to terminate such Plan in a "distressed termination" under the provisions of Section 4041 of ERISA; (3) the receipt of notice by the Borrower, any ERISA Affiliate or an administrator of a Plan that the PBGC has instituted proceedings to terminate (or appoint a trustee to administer) such a Plan; (4) and other event or condition exists which might, in the opinion of the Servicing Agent, constitute grounds under the provisions of Section 4042 of ERISA for the termination of or the appointment of a trustee to administer any Plan by the PBGC; (5) a Plan shall fail to maintain a minimum funding standard required by Section 412 of the IRC for any plan year or a waiver of standard is sought or granted under the provisions of Section 412(d) of the IRC; (6) the Borrower or any ERISA Affiliate has incurred, or is reasonably likely to incur, a liability under the provisions of Section 4062, 4036, 4046 or 4201 of ERISA; (7) the Borrower or any ERISA Affiliate fails to pay the full amount of an installment required under Section 412(m) of the IRC; or (8) the occurrence of any other event or condition with respect to any Plan which would constitute an event of default or default under any other agreement entered into by the Borrower or any ERISA Affiliate. 9. SERVICING AGENT'S AND LENDERS' RIGHTS AND REMEDIES 9.1 Rights and Remedies. Upon the occurrence and during the continuance of an Event of Default, Servicing Agent may, at its election, or shall, upon request of Requisite Lenders, without notice of its election and without demand, do any one or more of the following, all of which are authorized by Borrower: (a) Declare all Obligations, whether evidenced by this Agreement, by any of the other Loan Documents, or otherwise, immediately due and payable (provided that upon the occurrence of an Event of Default described in Section 8.5 all Obligations shall become immediately due and payable without any action by Servicing Agent or Lenders); (b) Cease advancing money or extending credit to or for the benefit of Borrower under this Agreement or under any other agreement between or among Borrower or Servicing Agent or any Lender; (c) With the continuation of an Event of Default for sixty (60) days or more, settle or adjust disputes and claims directly with account debtors for amounts, upon terms and in whatever order that Servicing Agent, with the approval of Requisite Lenders, reasonably considers advisable; (d) Without notice to or demand upon Borrower, make such payments and do such acts as Servicing Agent or Requisite Lenders in good faith consider necessary or reasonable to protect Servicing Agent's security interest in the Collateral. Borrower agrees to assemble the Collateral if Servicing Agent or Requisite Lenders so require, and to make the Collateral available to Servicing Agent as Servicing Agent or Requisite Lenders may designate. Borrower authorizes Servicing Agent, on behalf of each Lender, to enter the premises where the Collateral is located, to 38

take and maintain possession of the Collateral, or any part of it, and to pay, purchase, contest, or compromise any encumbrance, charge, or lien which in the Requisite Lenders' reasonable determination appears to be prior or superior to its security interest and to pay all expenses incurred in connection therewith. With respect to any of Borrower's premises, Borrower hereby grants Servicing Agent, on behalf of and for the benefit of Lenders, a license to enter such premises and to occupy the same, without charge, in order to exercise any of Lenders' rights or remedies provided herein, at law, in equity or otherwise; (e) Without notice to Borrower, set off and apply to the Obligations any and all (i) balances and deposits of Borrower held by any Lender or Servicing Agent, or (ii) indebtedness at any time owing to or for the credit or the account of Borrower owed or owing by any Lender or Servicing Agent; (f) Ship, reclaim, recover, store, finish, main- tain, repair, prepare for sale, advertise for sale, and sell (in the manner provided for herein) the Collateral. Servicing Agent is hereby granted a non-exclusive, royalty-free license or other right, solely pursuant to the provisions of this Section 9.1, to use, without charge, Borrower's labels, Patents, Copyrights, Mask Works, rights of use of any name, trade secrets, trade names, Trademarks, service marks, and advertising matter, or any property of a similar nature, as it pertains to the Collateral, in completing production of, advertising for sale, and selling any Collateral and, in connection with Servicing Agent's exercise of its rights under this Section 9.1, Borrower's rights under all licenses and all franchise agreements shall inure to Servicing Agent's benefit; (g) Sell the Collateral at either a public or private sale, or both, by way of one or more contracts or transactions, for cash or on terms, in such manner and at such places (including Borrower's premises) as Servicing Agent determines is commercially reasonable, and apply the proceeds thereof to the Obligations in whatever manner or order it deems appropriate; (h) Servicing Agent, on behalf of all Lenders, may credit bid and purchase at any public sale, or at any private sale as permitted by law; and (i) Any deficiency that exists after disposition of the Collateral as provided above will be paid immediately by Borrower. 9.2 Power of Attorney. Effective only upon the occurrence and during the continuance of an Event of Default, Borrower hereby irrevocably appoints Servicing Agent on behalf of and for the benefit of Lenders (and any of Servicing Agent's designated officers, or employees) as Borrower's true and lawful attorney to: (a) endorse Borrower's name on any checks or other forms of payment or security that may come into Servicing Agent's or Lenders' possession relating to the Collateral or any part thereof; (b) sign Borrower's name on any invoice or bill of lading relating to any Account, drafts against account debtors, schedules and assignments of Accounts, verifications of Accounts, and notices to account debtors; (c) make, settle, and adjust all claims under and decisions with respect to Borrower's policies of insurance relating to the Collateral or any part thereof; (d) settle and adjust disputes and claims respecting the Accounts directly with account debtors, for amounts and upon terms which Servicing Agent or Lenders determines to be reasonable; (e) modify, in its sole discretion, any intellectual property security agreement entered into between Borrower and Servicing Agent, without first obtaining Borrower's approval of or signature to such 39

modification, for the sole purpose of amending Exhibit A, Exhibit B, Exhibit C, and Exhibit D, thereof, as appropriate, to include reference to any right, title or interest in any Copyrights, Patents, Trademarks or Mask Works acquired by Borrower after the execution hereof or deleting any reference to any right, title or interest in any Copyrights, Patents, Trademarks, or Mask Works in which Borrower no longer has or claims any right, title or interest; (f) transfer the Intellectual Property Collateral into the name of Servicing Agent or a third party to the extent permitted under the Code; and (g) to file, in its sole discretion, one or more financing or continuation statements and amendments thereto, relative to any of the Collateral without the signature of Borrower where permitted by law; and provided Servicing Agent may exercise such power of attorney to sign the name of Borrower on any of the documents described in Section 4.2 regardless of whether an Event of Default has occurred. The appointment of Servicing Agent as Borrower's attorney in fact, and each and every one of Servicing Agent's rights and powers, being coupled with an interest, is irrevocable until all of the Obligations have been fully repaid and performed and Lenders' obligation to provide Credit Extensions hereunder is terminated. 9.3 Accounts Collection. Upon the occurrence and during the continuance of an Event of Default, Servicing Agent may notify any Person owing funds to Borrower of Servicing Agent's security interest in such funds. Borrower shall collect all amounts owing to Borrower on behalf of Servicing Agent, receive in trust all payments as Servicing Agent's and Lenders' trustee, and if required by Section 6.12, immediately deliver such payments to Servicing Agent in their original form as received from the account debtor, with proper endorsements for deposit. 9.4 Lenders' Expenses. If Borrower fails to pay any amounts or furnish any required proof of payment due to third persons or entities, as required under the terms of this Agreement, then Servicing Agent or Requisite Lenders may do any or all of the following: (a) make payment of the same or any part thereof; (b) set up such reserves under the Committed Revolving Line as Servicing Agent or Requisite Lenders deems necessary to protect Lenders from the exposure created by such failure; or (c) obtain and maintain insurance policies of the type discussed in Section 6.6 of this Agreement, and take any action with respect to such policies as such Lender deems prudent. Any amounts so paid or deposited by Servicing Agent or any Lender shall constitute Lenders' Expenses, shall be immediately due and payable, and shall bear interest at the then applicable rate hereinabove provided, and shall be secured by the Collateral. Any payments made by any Lender or Servicing Agent shall not constitute an agreement by such Lender or Servicing Agent to make similar payments in the future or a waiver by such Lender or Servicing Agent of any Event of Default under this Agreement. 9.5 Lenders' Liability for Collateral. So long as Lenders comply with reasonable banking practices, no Lender shall in any way or manner be liable or responsible for: (a) the safekeeping of the Collateral; (b) any loss or damage thereto occurring or arising in any manner or fashion from any cause; (c) any diminution in the value thereof; or (d) any act or default of any carrier, warehouseman, bailee, forwarding agency, or other person whomsoever other than such losses, costs, expenses or liabilities based upon or arising out of the gross negligence or willful misconduct of the Servicing Agent or such Lender. All risk of loss, damage or destruction of the Collateral shall be borne by Borrower. 9.6 Remedies Cumulative. Lenders' rights and remedies under this Agreement, the Loan Documents, and all other agreements shall be cumulative. Lenders shall have all other rights 40

and remedies, not expressly set forth herein, and as provided under the Code, by law, or in equity. No exercise by Lenders of one right or remedy shall be deemed an election, and no waiver by Lenders of any Event of Default on Borrower's part shall be deemed a continuing waiver. No delay by Lenders shall constitute a waiver, election, or acquiescence by it. No waiver by Lenders shall be effective unless made in a written document signed by all Lenders and Servicing Agent and then shall be effective only in the specific instance and for the specific purpose for which it was given. 9.7 Demand; Protest. Borrower waives demand, protest, notice of protest, notice of default or dishonor, notice of payment and nonpayment, notice of any default, notice of intent to accelerate, notice of acceleration, nonpayment at maturity, release, compromise, settlement, extension, or renewal of accounts, documents, instruments, chattel paper, and guarantees at any time held by Lenders or Servicing Agent on which Borrower may in any way be liable. 10.

EACH OF BORROWER, SERVICING AGENT AND LENDERS HEREBY SUBMIT TO THE EXCLUSIVE JURISDICTION OF THE STATE AND FEDERAL COURTS LOCATED IN THE COUNTY OF TRAVIS, STATE OF TEXAS. 12. PARTICIPATION 12.1 Participation Interest. Any Lender may at any time sell to one or more commercial banks or other Persons not Affiliates of Borrower ("Participant") participating interests in any Credit Extensions, the Commitment of such Lender and the other interests of such Lender ("Original Lender") hereunder and under the other Loan Documents; provided, however, that (i) the Original Lender's obligations under this Agreement shall remain unchanged, (ii) the Original Lender shall remain solely responsible for the performance of such obligations, (iii) Borrower shall continue to deal solely and directly with the Original Lender in connection with the Original Lender's rights and obligations under the Agreement and the other Loan Documents, and (iv) no Lender shall transfer or grant any participating interest under which the Participant shall have rights to approve any amendment to, or any consent or waiver with respect to, this Agreement or any other Loan Document. 12.2 No Obligation. Neither Lender shall have any obligation, implied or express, to assign, delegate, sell, offer to sell, purchase, offer to purchase or otherwise transfer in any way to any other party hereunder or any third party any participating interest hereunder or any or all of the Advances, the Commitments or the other rights and obligations of such Lender hereunder. 42

13. THE SERVICING AGENT 13.1 Appointment, Powers and Immunities. 13.1.1 Each Lender hereby appoints SVB as Servicing Agent hereunder and under the other Loan Documents and each Lender hereby irrevocably authorizes Servicing Agent to act hereunder and thereunder as Servicing Agent of such Lender. Servicing Agent agrees to act as such upon the express conditions contained in this Section 13. In performing its functions and duties under this Agreement and under the other Loan Documents, Servicing Agent shall act solely as Servicing Agent of Lenders and does not assume and shall not be deemed to have assumed any obligation towards or relationship of agency or trust with or for Borrower. 13.1.2 Each Lender irrevocably authorizes Servicing Agent to take such actions on such Lender's behalf and to exercise such powers hereunder as are specifically delegated to Servicing Agent by the terms hereof, together with such powers as are reasonably incidental thereto. Servicing Agent shall have only those duties which are specified in this Agreement and it may perform such duties by or through its agents, representatives or employees. In performing its duties hereunder on behalf of Lenders, Servicing Agent shall exercise the same care which it would exercise in dealing with loans made for its own account, but it shall not be responsible to any Lender for the execution, effectiveness, genuineness, validity, enforceability, collectability or sufficiency of all or any of the Loan Documents, or for any representations, warranties, recitals or statements made herein or therein or made in any written or oral statement or in any financial or other statements, instruments, reports, certificates or any other documents furnished or delivered in connection herewith or therewith by Servicing Agent to any Lender or by or on behalf of Borrower to Servicing Agent or any Lender, or be required to ascertain or inquire as to the performance or observances of any of the terms, conditions, provisions, covenants or agreements contained herein or therein or as to the use of the proceeds of the Advances of amounts drawn under the Letters of Credit. Servicing Agent shall not be responsible for insuring the Collateral or for the payment of any taxes, assessments, charges or any other charges or liens of any nature whatsoever upon the Collateral or otherwise for the maintenance of the Collateral, except in the event Servicing Agent enters into possession of a part or all of the Collateral, in which event Servicing Agent shall preserve the part in its possession. Unless the officers of Servicing Agent acting in their capacity as officers of Servicing Agent on Borrower's account have actual knowledge thereof or have been notified in writing thereof by Lenders, Servicing Agent shall not be required to ascertain or inquire as to the existence or possible existence of any Event of Default. Neither Servicing Agent nor any of its officers, directors, employees, representatives or agents shall be liable to Lenders for any action taken or omitted hereunder or under any of the other Loan Documents or in connection herewith or therewith unless caused by its or their gross negligence or willful misconduct. No provision of this Agreement or of any other Loan Document shall be deemed to impose any duty or obligation on Servicing Agent to perform any act or to exercise any power in any jurisdiction in which it shall be illegal, or shall be deemed to impose any duty or obligation on Servicing Agent to perform any act or exercise any right or power if such performance or exercise (i) would subject Servicing Agent to a tax in a jurisdiction where it is not then subject to a tax or (ii) would require Servicing Agent to qualify to do business in any jurisdiction where it presently is not so qualified. Without prejudice to the generality of the foregoing, no Lender shall have any right of action whatsoever against Servicing Agent as a result of Servicing Agent acting or (where so instructed) refraining from acting under this Agreement or under any of the other Loan Documents in accordance with the instructions of Lenders. Unless 43

otherwise directed by the Requisite Lenders under Section 9.1 or any other applicable provision of this Agreement, Servicing Agent shall be entitled to refrain from exercising any power, discretion or authority vested in it under this Agreement unless and until it has obtained written instructions of any Lender. The agency hereby created shall in no way impair or affect any of the rights and powers of, or impose any duties or obligations upon Servicing Agent in its individual capacity. 13.2 Representations and Warranties: No Responsibility for Inspection. Each Lender represents and warrants that it has made its own independent investigation of the financial condition and affairs of Borrower in connection with the making of the Advances and issuance of the Letters of Credit hereunder and has made and shall continue to make its own appraisal of the creditworthiness of Borrower. Servicing Agent shall have no duty or responsibility either initially or on a continuing basis to make any such investigation or any such appraisal on behalf of Lenders or to provide any Lender with any credit or other information (other than information obtained under the provisions of this Agreement which Servicing Agent shall make available to each Lender upon request by such Lender) with respect thereto whether coming into its possession before the date hereof or any times or times thereafter and shall further have no responsibility with respect to the accuracy of or the completeness of the information provided to Lenders. With respect to its participation in the Advances and the Letters of Credit hereunder, Servicing Agent shall have the same rights and powers hereunder as any other Lender and may exercise the same rights and powers as though it were not performing the duties and functions delegated to it hereunder and the term "Lender" or "Lenders" or any similar term shall unless the context clearly indicates otherwise include Servicing Agent in its individual capacity. Servicing Agent and each of its affiliates may accept deposits from, lend money to and generally engage in any kind of business with Borrower as if it were not Servicing Agent. 13.3 Reliance by Servicing Agent. 13.3.1 Servicing Agent may consult, and any opinion or legal advice of such counsel who are not employees of Servicing Agent or Borrower or any Affiliate of Borrower shall be full and complete authorization and protection in respect of any action taken or suffered by Servicing Agent hereunder or under any other Loan Documents in accordance therewith. Servicing Agent shall have the right at any time to seek instructions concerning the administration of the Collateral from any court of competent jurisdiction. 13.3.2 Servicing Agent may rely, and shall be fully protected in acting, upon any resolution, statement, certificate, instrument, opinion, report, notice, request, consent, order, bond or other paper or document that it has no reason to believe to be other than genuine and to have been signed or presented by the proper party or parties or, in the case of cables, telecopies and telexes, to have been sent by the proper party or parties. In the absence of its gross negligence or willful misconduct, Servicing Agent may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to Servicing Agent and conforming to the requirements of this Agreement or any of the other Loan Documents. 13.3.3 Except as specifically provided for herein, Servicing Agent shall not be under any obligation to exercise any of the rights or powers granted to Servicing Agent by this Agreement and the other Loan Documents at the request or direction of any Lender unless Servicing 44

Agent shall have been provided by such Lender adequate security and indemnity against the costs, expenses and liabilities that may be incurred by it in compliance with such request or direction. 13.4 Delegation of Duties. Servicing Agent may execute any of the powers hereof and perform any duty hereunder either directly or by or through its agents or attorneys-in-fact. Servicing Agent shall be entitled to advice of counsel concerning all matters pertaining to such powers and duties. Servicing Agent shall not be responsible for the negligence or misconduct of any agents or attorneys-in-fact selected by it without gross negligence or willful misconduct on the part of Servicing Agent. 13.5 Right to Indemnity. EACH OF LENDERS SEVERALLY, BUT NOT JOINTLY, AGREES (A) TO INDEMNIFY AND HOLD SERVICING AGENT (AND ANY PERSON ACTING ON BEHALF OF SERVICING AGENT) HARMLESS FROM AND AGAINST AND (B) PROMPTLY ON RECEIPT BY EACH LENDER OF SERVICING AGENT'S STATEMENT, TO REIMBURSE SERVICING AGENT, ACCORDING TO SUCH LENDER'S PRO RATA SHARE OF THE AGGREGATE COMMITMENTS, TO THE EXTENT SERVICING AGENT SHALL NOT OTHERWISE HAVE BEEN REIMBURSED BY BORROWER ON ACCOUNT OF AND FOR, ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES (INCLUDING, WITHOUT LIMITATION, THE FEES AND DISBURSEMENTS OF COUNSEL AND OTHER ADVISORS) OR DISBURSEMENTS OF ANY KIND AND NATURE WHATSOEVER WITH RESPECT TO SERVICING AGENT'S PERFORMANCE OF ITS DUTIES UNDER THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; PROVIDED, HOWEVER, THAT NO LENDER SHALL BE LIABLE FOR THE PAYMENT TO SERVICING AGENT OF ANY PORTION OF SUCH LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES OR DISBURSEMENTS RESULTING SOLELY FROM SERVICING AGENT'S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. SUCH REIMBURSEMENT SHALL NOT IN ANY RESPECT RELEASE BORROWER FROM ANY LIABILITY OR OBLIGATION. IF ANY INDEMNITY FURNISHED TO SERVICING AGENT FOR ANY PURPOSE SHALL, IN THE OPINION OF SERVICING AGENT, BE INSUFFICIENT OR BECOME IMPAIRED, SERVICING AGENT MAY CALL FOR ADDITIONAL INDEMNITY AND CEASE, OR NOT COMMENCE, TO DO THE ACTS INDEMNIFIED AGAINST UNTIL SUCH ADDITIONAL INDEMNITY IS FURNISHED. 13.6 Resignation and Appointment of Successor Servicing Agent. (a) Servicing Agent may resign at any time by giving thirty (30) days prior written notice thereof to Lenders and Borrower: provided, however, that the retiring Servicing Agent shall continue to serve until a successor Servicing Agent shall have been selected and approved pursuant to this Section 13.6. Upon any such notice, Servicing Agent shall have the right to appoint a successor Servicing Agent; provided, however, that if such successor shall not be a Lender under this Agreement, such appointment shall be subject to the consent of Requisite Lenders. At any time other than during the existence of an Event of Default, in each case, such appointment shall be subject to the prior consent of Borrower (such consent to not be unreasonably withheld, delayed or conditioned). (b) Servicing Agent agrees at all times to abide by the terms and conditions of this Agreement and at all times to maintain the minimum regulatory capital requirements, as set by the Federal Reserve Board, for an adequately capitalized depository institution, and Servicing Agent undertakes and agrees to notify each Lender promptly of any failure by Servicing Agent to 45

maintain such minimum regulatory capital requirements. If Servicing Agent ever defaults in the performance of its duties and obligations under this Agreement and such default remains uncured and continues for more than thirty (30) days after written notice of such default is given to Servicing Agent by any Lender, or if Servicing Agent ever allows its regulatory capital requirements to fall below the minimum regulatory capital requirements for an adequately capitalized depository institution, any Lender which is not also acting as the Servicing Agent hereunder may remove such Servicing Agent from acting as Servicing Agent hereunder and appoint a successor Servicing Agent (which may be the Lender so removing the Servicing Agent) by delivering written notice thereof to the Borrower, the Servicing Agent being removed hereunder and any other Lenders, if any; provided, however, that if such successor Servicing Agent shall not be a Lender hereunder, such appointment shall be subject to the prior approval of Borrower (such consent to not be unreasonably withheld, conditioned or delayed), so long as no Event of Default is then occurring hereunder. (c) Upon the acceptance of any appointment as an Servicing Agent hereunder by a successor Servicing Agent, such successor Servicing Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring or removed Servicing Agent, and the retiring or removed Servicing Agent shall be discharged from its duties and obligations under this Agreement. After any retiring or removed Servicing Agent's resignation or removal hereunder as Servicing Agent, the provisions of this Section 13 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Servicing Agent under this Agreement. 13.7 Conflicts. SVB and its affiliates may accept deposits from, lend money to, act as trustee under indentures of, act as merchant banker in any transaction for, and generally engage in any kind of business with, Borrower and any person who may do business with or own securities of Borrower, all as if SVB were not Servicing Agent and without any duty to account therefor to Lenders or to disclose to Lenders confidential information which SVB may receive from Borrower in connection with such other activity or business. 13.8 No Obligations of Borrower. Nothing contained in this Section 13 shall be deemed to impose upon Borrower any obligation in respect of the due and punctual performance by Servicing Agent of its obligations to Lenders under any provision of this Agreement, and Borrower shall have no liability to Servicing Agent or any Lender in respect of any failure by Servicing Agent or any Lender to perform any of their respective obligations to each other under this Agreement. Without limiting the generality of the foregoing sentence, where any provision of this Agreement relating to the payment of any amounts due and owing under the Loan Documents provides that such payments shall be made by Borrower to Servicing Agent for the account of Lenders, Borrower's obligations to Lenders in respect of such payments shall be deemed to be satisfied upon the making of such payments to Servicing Agent in the manner provided by this Agreement. 13.9 Amendments in Writing; Integration. This Agreement cannot be amended or terminated nor may any provision be waived except by a writing signed by the Requisite Lenders, Servicing Agent and Borrower. Any such waiver shall be effective only in the specific instance and for the specific purpose for which given. As between Borrower, on the one hand, the Lenders and Servicing Agent on the other hand, all prior agreements, understandings, representations, warranties, and negotiations between the parties 46

hereto with respect to the subject matter of this Agreement, if any, are merged into this Agreement and the Loan Documents. 14. GENERAL PROVISIONS 14.1 Successors and Assigns. This Agreement shall bind and inure to the benefit of the respective successors and permitted assigns of each of the parties; provided, however, that neither this Agreement nor any rights hereunder may be assigned by Borrower without each Lender's prior written consent, which consent may be granted or withheld in each Lender's sole discretion. 14.2 INDEMNIFICATION. BORROWER SHALL, INDEMNIFY, DEFEND, PROTECT AND HOLD HARMLESS SERVICING AGENT AND EACH LENDER AND EACH'S RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES, AND AGENTS AGAINST: (A) ALL OBLIGATIONS, DEMANDS, CLAIMS, AND LIABILITIES CLAIMED OR ASSERTED BY ANY OTHER PARTY IN CONNECTION WITH THE TRANSACTIONS CONTEMPLATED BY THE LOAN DOCUMENTS; AND (B) ALL LOSSES OR LENDER'S EXPENSES INCLUDING WITHOUT LIMITATION REASONABLE ATTORNEYS' FEES AND EXPENSES, IN ANY WAY SUFFERED, INCURRED, OR PAID BY SERVICING AGENT OR ANY LENDER AS A RESULT OF OR IN ANY WAY ARISING OUT OF, FOLLOWING, OR CONSEQUENTIAL TO TRANSACTIONS BY AND AMONG LENDERS, SERVICING AGENT AND BORROWER WHETHER UNDER THE LOAN DOCUMENTS, OR OTHERWISE INCLUDING ANY LENDER'S OR SERVICING AGENT'S NEGLIGENCE BUT EXCLUDING LOSSES CAUSED BY SERVICING AGENT OR ANY LENDER'S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. 14.3 Time of Essence. Time is of the essence for the performance of all obligations set forth in this Agreement. 14.4 Severability of Provisions. Each provision of this Agreement shall be severable from every other provision of this Agreement for the purpose of determining the legal enforceability of any specific provision. If any term, provision, covenant, or condition of this Agreement is held by a court of competent jurisdiction to be invalid, void, or unenforceable, the remainder of the provisions shall remain in full force and effect and shall in no way be affected, impaired, or invalidated and this Agreement shall be construed as if such invalid, void or unenforceable provision had never been contained herein. 14.5 Counterparts. This Agreement may be executed in any number of counterparts and by different parties on separate counterparts, each of which, when executed and delivered, shall be deemed to be an original, and all of which, when taken together, shall constitute but one and the same Agreement. 14.6 Survival. All covenants, representations and warranties made in this Agreement shall continue in full force and effect so long as any Obligations remain outstanding. The obligations of Borrower to indemnify Lenders and Servicing Agent with respect to the expenses, damages, losses, costs and liabilities described in Section 14.2 shall survive until all applicable statute of limitations periods with respect to actions that may be brought against Lenders or Servicing Agent have run. 47
