ITEM 1.  BUSINESS.

                                  INTRODUCTION

     Xybernaut Corporation, a Delaware corporation (the "Company"), is engaged
in the research, development and commercialization of mobile computing and
communication systems along with related software solutions designed to enhance
personal productivity and improve the accuracy, timeliness and utilization of
captured data. The Company's current mobile computing and communications product
is the Mobile Assistant(R) IV (MA IV(R)) model.

     The MA IV is a wearable Pentium(R) PC which combines the speed, memory,
processing, multimedia and communications capabilities of a desktop personal
computer ("PC") in a lightweight, user-supported unit with hands-free operation
and simultaneous user mobility. The MA IV is a combination of hardware and
software designed to be worn on the body to perform complex and time consuming
tasks such as remote video teleconferencing, installation, maintenance, repair
and inspection of complex technological and mechanical systems, retrieval and
analysis of medical information from remote locations, and coordination of
remote commercial and industrial activities, or military field operations.

     The MA IV incorporates technologically advanced optional features such as
real-time, two-way video and audio communications through radio frequency
transmissions or integrated cellular linkups, global positioning system tracking
capabilities and access to information through the Internet and World Wide Web.
The head-mounted display ("HMD") unit includes a two-way audio system and
optional built-in video camera, weighs approximately l5 ounces and presents a
desk-top quality full VGA color image that is approximately equivalent to that
of a 15" VGA monitor at a distance of two feet. An optional light-weight, 6.4
inch, full VGA color, flat panel display ("FPD"), with integrated digitizer, is
offered for users who either do not desire an HMD, do not need to be hands-free
to perform their job, or need to capture signatures and other forms-related
data. The body-worn computing unit is designed to allow operation in
environmental conditions in which conventional portable computers could not
previously operate, weighs less than two pounds and is designed to run software
applications designed for Microsoft(R) Windows(R) 3.11, Windows 95, 98, Windows
NT(TM), DOS, SCO UNIX(R) and LINUX.

     The Company currently offers a multi-media development toolkit and the
linkAssist(TM) software package, which is designed to get user documentation up
and running on the Mobile Assistant(R), or any PC, quickly by providing a
windows-style graphical user interface ("GUI") and the ability to link data
stored in most formats in most locations without disturbing the original data.
This software can also be used on conventional desktop or laptop computers and
features automatic speech enablement of hyperlinks across platforms, formats,
and media. The Company has also established a professional services group to
provide custom solutions development for its customers and to provide needs
assessment and implementation assistance for solutions involving wearable
applications.

     The Company's executive and administrative offices are located at 12701
Fair Lakes Circle, Fairfax, Virginia 22033. Its telephone number is (703)
631-6925, and its e-mail address for investor inquiries is
[email protected].

                           FORWARD-LOOKING STATEMENTS

     To keep investors informed of the Company's future plans and objectives,
this Annual Report on Form 10-KSB (and other reports and statements issued by
the Company and its officers from time to time) contain certain statements
concerning the Company's future results, future performance, intentions,
objectives, plans and expectations that are or may be deemed to be
"forward-looking statements." The Company's ability to do this has been fostered
by the Private Securities Litigation Reform Act of 1995 which provides a "safe
harbor" for forward-looking statements to encourage companies to provide
prospective information so long as those statements are accompanied by
meaningful cautionary statements identifying important factors that could cause
actual results to differ materially from those discussed in the statement. Such
forward-
                                        2
<PAGE>   3

looking statements are subject to a number of known and unknown risks and
uncertainties that, in addition to general economic and business conditions,
could cause the Company's actual results, performance, and achievements to
differ materially from those described or implied in the forward-looking
statements. Factors that could cause or contribute to such differences include,
but are not limited to, the Company's ability to profit from the Mobile
Assistant(R) as expected (see "Products and Product Development"), the Company's
ability to meet competition (see "Competition"), the Company's ability to
maintain superior technological capability, foreseeing changes and continuing to
identify, develop and commercialize innovative and competitive products and
systems (see "Research and Development"), the Company's ability to penetrate
different markets and successfully expand its market base (see "Marketing and
Sales"), the Company's ability to attract and retain technologically qualified
personnel, particularly in the areas of research and development (see
"Employees"), and the Company's ability to generate cash flows and obtain
financing to support its operations and growth (see "Management's Discussion and
Analysis of Financial Condition and Results of Operations" in Item 7 of this
Annual Report on Form 10-KSB).

                               INDUSTRY OVERVIEW

     There has been an ongoing evolution to personalize the computer by moving
it physically closer to the user, from mainframes, to distributed systems, to
desktops, to notebooks and now to wearable systems. The commercialization of
mobile computing products combined with significant increases in the number and
scope of software applications has resulted in a multi-billion dollar market. In
addition, the rapid growth in the World Wide Web of the Internet has resulted in
computers increasingly being used as communication tools as well as computing
tools. Advances in wireless communications have accelerated this convergence of
computing and communications as cell phones and personal digital assistants
("PDAs") have added computing or wireless communicating capabilities to serve as
such convergence devices for mobile use. Wireless local area networks ("LANs")
now operate at sufficient speeds to allow the Company's MA IV to function as
"just another node on the network" by running existing desktop applications in a
wireless mode on a network with little to no modification.

     The Company believes that users looking for mobile computing and
communications capabilities through cellular phones, pagers, PDAs, portable
email devices and portable computers will increasingly demand that one device
provide these capabilities rather than the many devices that are currently
required. The Company believes that its wearable PC products are uniquely suited
to meet this demand, that limited-capability or special-purpose devices will
eventually be replaced by wearable PCs that provide consistent interfaces and
full functionality no matter whether they are used in an office, travel, home or
automobile environment. The Company believes that the potential to develop a
substantial market for its mobile computing and communication hardware and
software products is demonstrated by the substantial historic and projected
growth in all forms of mobile computing and communication devices.

     In conjunction with this personalization of hardware has come a
personalization of software to provide the user with the information they need
to perform the task at hand and the expansion of Enterprise Resource Planning
("ERP") systems that extend computing capabilities across an organization, not
just within certain functions of the organization. A recent study by IDC on
wearable computers stated that approximately half of the workers at large U.S.
companies do not work at a fixed location and do not have access to their
company's information technology as they move around. A study by the Gartner
Group concluded that 137 million workers worldwide do not work at a fixed
location. The Company believes that its products and services are ideally
positioned to provide information access to this pool of workers, and allow the
companies in this situation to leverage their existing investment in information
technology to this "other half" of their workforce. Further, the Company
believes that its products and services are also ideally suited to capture the
growing consumer interest in computing and communications devices.

                               BUSINESS STRATEGY

     The Company's objective is to be the leading provider of hands-free mobile
computing and communication systems, along with related solutions and software
to enhance productivity in a wide variety of applications. To achieve this
objective, the Company intends to pursue the following strategies:

     LEVERAGE CORE COMPETENCIES.  The Company believes its core competencies,
which have been developed since its inception, are the integration and
adaptation of innovative computer hardware and software technologies into
hands-free, mobile computing and communications solutions that enhance end user
productivity. The Company will seek to expand applications for its technologies
and to capitalize on the breadth of its expertise by developing new hardware and
software products. Consistent with this strategy, the Company will continue to
focus on the integration of hands-free mobile computing hardware with internally
developed, licensed or acquired software applications and hardware products. To
leverage these core competencies, the Company has established a number of
strategic alliances and intends to continue to have its strategic partners play
a significant role in executing the Company's manufacturing, service, sales and
marketing functions, under close coordination with Company management. The
Company intends to remain focused, able to react quickly to market needs and
world economic changes. The Company believes that this structure will allow the
Company to expand its revenues without the need to add internal resources in
direct proportion to increases in revenues.

     DEVELOP AND STRENGTHEN STRATEGIC ALLIANCES.  The Company has established
and intends to continue to establish strategic alliances with world-class
partners to provide the execution capabilities required by the Company in such
areas as product development, manufacturing, sales, distribution and marketing.
The benefits that the Company receives from these associations include access to
a larger potential customer base, complementary technologies, reduced capital
investment through utilization of outside resources, and access to manufacturing
expertise and efficiencies of world-class manufacturers.

     The Company has entered into distribution and support agreements with En
Pointe Technologies, Academic Distributing, PAMAS and D&H Distributing.
Additionally, large systems integrators, such as DynCorp, provide both
implementation support for Xybernaut customers worldwide as well as place our
products within their own client bases. The Company has been pursuing, and will
continue to pursue, additional strategic associations to enhance its product
offerings and expand its marketing activities.

     In addition to these marketing and supporting strategic relationships, the
Company has signed agreements and is executing additional relationships with
organizations such as the Softwarezentrum Boeblingen/ Sindelfingen e.V. (SBS) in
Europe with over 30 software companies serving as a development center for
Linux, speech and wearable applications, and companies in the USA and Asia for
development and field testing of application-specific solutions for industry.

     STRENGTHEN PATENT AND INTELLECTUAL PROPERTY.  The Company has developed a
portfolio of over 470 patent applications granted or pending worldwide as the
base for its intellectual property for wearable computing and communications and
related software solutions (see "Patents"). The Company intends to continue
building and strengthening this portfolio, which it considers to be one of its
most significant assets and potential revenue sources.

     PROVIDE CUSTOM SOFTWARE SOLUTIONS FOR DIVERSE CUSTOMER NEEDS.  The Company
intends to continue acquiring, developing or licensing software that enables its
customers to more rapidly create customized software applications for use with
the Mobile Assistant Series and on conventional PCs. This software will be
designed to provide prepackaged application expertise that incorporates the end
user's existing programs, procedures and technical documentation to the greatest
extent possible. This will permit the cost-effective development of
productivity-enhancing software applications by customers. To date, revenue from
the sales of software products have not been material, however, the Company
believes that revenue from software will become an important contributor to
operating margins in the future.

     PENETRATE TARGET MARKETS USING SELECTED CHANNELS.  The Company intends to
continue penetrating its target markets through its direct sales force,
licensing and the effective use of VARs (Value-Added Resellers), ISVs
(Independent Software Vendors) and distributor channels that demonstrate
comprehensive
                                        4
<PAGE>   5

market knowledge in their sectors. The objective of the direct sales force is to
establish initial sales and relationships with customers and then turn them over
to the appropriate outside channel for development. The Company believes that by
combining the established customer base of VARs, ISVs, and distributors with the
benefits provided by the Company's products and services, sales can be
accelerated much faster than by using a direct sales force alone. Through the
use of its strategic partners, the Company intends to leverage internal
marketing and sales resources to achieve more rapid foreign and domestic market
penetration. The Company also intends to continue marketing directly to key
national accounts in order to build multiple reference accounts for its
distributors to use to quickly expand their own world wide sales. These
reference accounts will also provide the Company's research and development
organization with valuable direct feedback from customers for future product
development. The Company expects large computer and equipment manufacturers will
desire to enter the wearable or user-supported computing marketplace, and that
it will have numerous opportunities to license its intellectual property. Such
licensing, the Company believes, will yield significant revenue as well as
accelerated market penetration of mobile computing hardware and software.

     ACHIEVE AND MAINTAIN TECHNOLOGY LEADERSHIP.  The Company is committed to
achieving and maintaining technological superiority of the Mobile Assistant
Series and its other mobile computing hardware and software products through the
continuous reassessment of product performance and the utilization and
integration of state-of-the-art hardware and software technologies. The Company
believes that the substantial time, effort and resources expended in developing
the Mobile Assistant Series has resulted in a set of core competencies which
provides the Company with a solid foundation in the hands-free, mobile computing
industry. The Company intends to maintain this advantage through ongoing
research and development, which will ensure that the Mobile Assistant Series
will continue to provide a full range of computing and communications
capabilities, such as two-way wireless video communication and access to the
Internet, intranets, remote databases and other computerized reference
resources. The Company also intends to pursue joint developments with its
strategic partners and licensing of its intellectual property to build and
market new technology. The current MA IV Series, for example, was the result of
the Company's successful relationships with Fujitsu, Sony Digital Products,
Hitachi, Shimadzu, Toshiba, JAE and NEC, all under the direction of the
Company's staff.

     COMMITMENT TO OPEN ARCHITECTURE.  The Company utilizes standard PC hardware
and software architectures and designs its products using open systems
technologies, including industry standard operating systems. This open approach
has allowed the Company to readily incorporate state-of-the-art wireless
communications, GPS, sensor and other capabilities as soon as they are available
for use in laptops, especially when these capabilities are provided using
industry-standard PCMCIA cards. In addition, this strategy has allowed the
Company to take advantage of developments in operating systems, such as new
generations of Windows and Linux, and applications software, such as speech.

                        PRODUCTS AND PRODUCT DEVELOPMENT

     In order to address the market for body-worn mobile computing and
communication systems, the Mobile Assistant Series has been designed to provide
hands-free wearable operation of computing and communications capabilities on a
"when-needed, where-needed" basis. The hardware used in the MA IV features:

     - Intel Pentium(R) processor with 512 KB Level Two (L2) cache, Synchronous
       DRAM (SDRAM) currently ranging from 32 Megabytes (MB) to 192 MB, an
       internal hard disk of up to 8.1 Gigabytes (GB) with a complete array of
       USB, serial, parallel, monitor, keyboard, power and replicator ports.

     - Protected internal dual PCMCIA (PC Card) readers, a sealed enclosure to
       allow use in a wide range of environmental conditions,
       advanced-technology, hot-swappable lithium-ion battery and charger,
       integrated pointing device, built-in sound system for speech recognition
       and generation, and a wrist-mounted miniature keyboard.

     - Head Mounted and/or Flat Panel Displays with a head-mounted camera to
       allow for real-time, two-way audio/video teleconferencing. The MA IV uses
       a lightweight HMD with 640 X 480 pixels (VGA

                                        5
<PAGE>   6

       color). It is anticipated that this display will be offered in color SVGA
       800 X 600, and XGA 1280 X 1024 pixel resolutions, and eventually in color
       resolutions comparable to those planned for high-definition TV. The
       Active Matrix Liquid Crystal Display (AMLCD) used in the head mounted
       display is currently approximately one square inch in size and uses
       advanced optics to present an image to the user that is equivalent to a
       15" desktop monitor at a distance of two feet. The MA IV uses an optional
       light-weight, 6.4 inch, full VGA color FPD with integrated digitizer,
       which is offered for users who do not desire a HMD or do not need to be
       100% hands-free. The FPD can also be speech-activated and contain a
       built-in speaker.

     - Mini-port replicator for mobile use and a full port replicator for
       complete desk-top functionality.

     - Compatibility with MS-DOS, Windows 3.11, Windows 95 and 98, Windows NT,
       SCD, UNIX and LINUX operating systems.

     The Mobile Assistant Series are full-featured PCs that can be readily used
as a desktop PC and can incorporate a wide range of capabilities including
portable CD-ROM readers, bar code readers, battery-operated printers, still and
motion video cameras, global positioning technologies, cellular and radio
frequency communications and interfaces for medical, test and sensor equipment.

     HANDS-FREE CONTROL.  From the origination of the concept for wearable
computers, the Company has believed that hands-free control of the computer is
essential to realizing the maximum benefits of wearable computing and
communications. The original method of hands-free control was speech
recognition. The Mobile Assistant supports state-of-the-art speech recognition
software and hardware to allow for hands-free operation using spoken commands in
most languages. The combination of voice recognition and body-worn displays
provide the user of the Mobile Assistant with hands-free access to information
and the ability to apply this information to operations and tasks with direct
lines of sight and tactile access. User-independent speech generally requires
little or no training and is ideal for command-and-control applications to
operate the computer from menu-driven software. User-dependent speech systems
generally require some training to provide for a wider usable vocabulary and the
ability to offer dictation. The MA IV currently comes with IBM Via Voice(R) but
can operate most user-dependant and user-independent software systems designed
for PC use. The selection of which speech system to use is generally driven by
the application requirements. In addition to speech control, the Company has
included brain-wave activation, eye tracking and motion tracking in its patents
as alternative approaches to speech for hands-free control.

     FLAT PANEL DISPLAY.  The MA IV uses an optional light-weight, 6.4 inch,
full VGA color FPD with integrated digitizer. It is offered for users who do not
desire an HMD or do not require full hands-free operation. The FPD can also be
speech-activated and contains a built-in speaker.

     COMPUTER SOFTWARE FOR MOBILE, BODY-WORN AND DESK-TOP USE.  Currently, the
Company offers linkAssist, which is designed to get user documentation up and
running on the Mobile Assistant quickly, and which can also be used on
conventional desktop or laptop computers. The Company's linkAssist software
allows users to quickly and easily link information together regardless of the
format of the data or where it is stored, avoiding the need to change, convert
or re-enter and verify the existing information in any manner, or to use the
detailed HTML tagging process. The linked words or phrases can then be activated
by voice automatically, with no development work required by the author of the
documentation or databases, allowing a subject-matter expert to develop
applications with little training. In addition to linkAssist, the Company offers
a multi-media development (MMD) kit, which allows customers to develop
applications using video, audio, text and graphics.

     DEVELOPMENT OF FUTURE PRODUCTS.  The Company's approach to development of
future products is to establish functional requirements, specifications and
design criteria internally, then to take those criteria to potential development
partners under non-disclosure agreements to evaluate the ability of that
development partner to meet the Company's needs. The Company is in discussions
with IBM and a number of other world-class technology companies regarding
collaboration on its next-generation of wearable computers. The Company's
selection criteria for partners to develop this next-generation will be based on
pricing, the ability to provide reliable, advanced technology, production
capacity and reputation in the worldwide markets for

                                        6
<PAGE>   7

technology products. It is expected that future products will allow the Company
to directly address segments of the consumer market.

                              MARKETING AND SALES

MARKETS

     The Company's current marketing efforts are designed to increase awareness
of, and demand for, its products in the commercial, industrial and military
markets while establishing a base for the Company's plans to enter consumer
interests. The following are examples of selected horizontal and vertical
markets that are being addressed by the Company:

          COMMERCIAL MAINTENANCE AND REPAIRS.  Information from the United
     States Bureau of Labor Statistics and Bureau of Census indicates that as of
     1996 there were more than 5,460,000 commercial mechanics and technicians in
     the United States, all of which the Company believes are potential users of
     the Mobile Assistant Series and its other products. There are many sources
     of savings available from use of the Mobile Assistant Series and the
     Company's other products in maintenance and repair operations. For example,
     less formal training is required for a similar level of performance, the
     time required for diagnostic and repair tasks is reduced as "just in time"
     refreshers and improved technical information can be provided, and
     personnel can address a wider range of complex tasks or products with the
     same level of basic training. While these savings can be realized in most
     industries, the Company anticipates that these savings will be most
     immediate and apparent in those industries that require a large investment
     in equipment and machinery, including industries such as manufacturing,
     transportation, aerospace, telecommunications, automotive, construction,
     power generation, health services, agriculture and the military.
     Accordingly, a reduction measured in minutes or hours of downtime in these
     industries can, in the Company's view, provide ample cost justification for
     a Mobile Assistant. The telecommunications industry is expected to be a
     prime candidate for mobile computing systems given the industry's complex
     technologies, increased competition and assets spread over a wide
     geographic area. The Mobile Assistant can provide needed knowledge to
     workers in virtually any location. Locations may include the top of a
     telephone pole, a remote relay station or in a conduit tunnel. Crew
     locations can be monitored and coordinated in the field with the Mobile
     Assistant through optional global positioning system technology and
     telecommunication capability. Crews at remote locations can consult with
     experts using the Company's two-way audio and/or video communications
     products.

          HEALTH SERVICES.  According to the National Center for Health
     Statistics, in 1995 the United States spent approximately 13.6% of the U.S.
     Gross Domestic Product, or approximately $1 trillion on healthcare, with an
     estimated 25% of such expenses consumed by administrative expenses.
     According to the National Center for Health Statistics, United States,
     1994, the United States has over 6,000 hospitals and over 540 health
     maintenance organizations. According to the United States Department of
     Labor, in 1994 there were approximately 4,714,000 healthcare workers in the
     United States. The Company believes that many of the current processing and
     data systems used in healthcare, both in institutions and in the field, are
     not well developed or integrated and that hands-free mobile computing
     systems could reduce expenses and increase efficiency in this industry. The
     Mobile Assistant is believed to present great potential in field medical
     operations by providing on-board and remote diagnostics, audio and/or video
     communication with doctors for emergency procedures, and transmission of
     locations for helicopter pickup through global positioning systems
     integrated into the Mobile Assistant. Another anticipated benefit of the
     Company's hands-free mobile computing technologies is that fewer healthcare
     personnel will be needed to perform complex tasks. By providing remote
     delivery of medical information ("telemedicine"), the Company's hands-free
     mobile computing systems can become a key component within both managed
     care and telemedicine organizations, which are two key submarkets
     developing within the healthcare industry.

          PUBLIC SECTOR.  The Company has demonstrated the ability of its
     technology to aid in law enforcement, transportation, fire protection,
     emergency services, inspection and control of national borders.

          EDUCATION.  The Company believes that its mobile computing systems are
     well suited for educational applications. The Mobile Assistant is
     especially suited for distance learning as well as hands-free applications,
     such as laboratory work, field research and dissections, and has the
     potential to serve as a mobile student workstation. In addition, it can
     provide an ideal computing and control platform for special education and
     handicapped needs.

          MILITARY.  There are several current and potential military
     applications for the Company's hands-free mobile computing systems,
     including intelligence, maintenance and field operations. The military has
     long been an early adopter of advanced weapons technologies and as a
     result, was one of the first sectors to experience problems with the
     ability of personnel to maintain, diagnose and repair the advanced
     technology employed in both weapons and equipment. The downsizing of the
     United States military and related budget constraints have compounded these
     problems. As a result, even greater pressure will be placed upon the
     military to maintain its equipment and weapons platforms with fewer
     personnel. The Company believes that most of the estimated 700,000 military
     maintenance personnel in the United States could be made more efficient and
     productive by the Company's hands-free mobile computing systems.

     The United States military's increasingly sophisticated weapon systems
require volumes of operational and technical manuals and have dramatically
increased the importance of, and reliance on, maintenance. For example, the
United States Army has purchased the Mobile Assistant and has tested its use in
the maintenance and repair of the AH64 Apache Attack helicopter and M1A1 battle
tank. The Apache can send and receive maintenance data via an industry standard
electrical interface that can be read by an optional interface for the Mobile
Assistant. Operating and performance data can be downloaded directly from the
Apache, and the Mobile Assistant can be used to diagnose existing and potential
maintenance and repair problems. The Company anticipates that manufacturers of
complex military and commercial equipment increasingly will incorporate
integrated data collection and transmission capabilities into their technologies
to reduce downtime, repair and maintenance related costs.

     The ability to deliver information to soldiers in combat field operations
is the focus of several development programs sponsored by the United States
Military to simulate combat maneuvers using body-worn computing components,
including those provided by the Company, to determine effectiveness for use in
coordinating troop locations and movements, determining enemy locations, and
using global positioning systems to provide coordinates for artillery,
helicopter pickup and air support.

     The Company has already sold systems to the United States Military, and
expects that its sales partners will sell heavily into the armed services both
in the USA and overseas.

  MARKETING

     Because the Company's products are frequently combined with products and
services from other companies to form integrated information systems, the
Company believes that it is more effective to sell through distributors, systems
integrators, industrial and commercial equipment manufacturers, independent
software vendors and VARs with defined market niche expertise and presence, as
well as directly to end users. In conjunction with the introduction of the MA
IV, the Company established arrangements with specialized distributors for
higher volume distribution of the MA IV. The Company believes that by forming
relationships with these partners the Company can then reach end users more
rapidly in a variety of industries while minimizing the internal resources
required to reach these end users.

     The Company has offered detailed in-house training sessions to prepare and
update personnel for field sales and training. In addition, the Company has
developed comprehensive sales and operations manuals to be used by these
channels and end users. The Company's marketing and sales employees are
responsible for implementing direct marketing plans and sales programs, and
coordinating sales activities with sales and

                                        8
<PAGE>   9

marketing and service partners. The fulfillment of orders will be accomplished
mainly through distribution partners, regardless of which entity effects the
actual sales.

  SALES AND BACKLOG

     As of December 31, 1999 the Company had a negligible backlog of orders.
While the Company had several blanket purchase orders from customers outstanding
at that time, it does not include these amounts in backlog until specific orders
are received under these blanket purchase orders. Given the Company's current
inventory position, most orders are filled within a short period after the
receipt of the order and management does not feel that backlog is an appropriate
measure of demand at this time. Customers who have placed orders in the past
include, among others, Boeing, Lucent, Niagara Mohawk, DaimlerChrysler, Dyncorp,
BOC Gas, NTT (Nippon Telegraph and Telephone), Fujitsu, Mitsubishi, Lockheed
Martin and the United States Army. Purchase orders are generally cancelable by
the customers without penalty and are not binding upon the customer.

  LICENSE GRANTED TO THE COMPANY BY DATA DISK

     During 1997, the Company entered into a series of agreements with Data-Disk
Technology, Inc., a Virginia-based company, that produces a memory product known
as the Data Disk that consists of a non-volatile memory chip encapsulated in a
rugged polymer casing slightly smaller than a soldier's "dogtag" that is highly
resistant to temperature and environmental conditions. The Company's management
believes that the Data Disk provides an ideal storage medium for body-worn
computer applications, especially those that involve a large number of people,
inspection sites or equipment. These tags can be used to store information such
as medical history, repair history or other data unique to an individual or a
piece of equipment and from which information can be read by inserting the tag
into a reader that fits in the existing PC card slots on the Mobile Assistant.
Under the agreement with Data Disk, the Company received an exclusive, perpetual
worldwide license to use and sell present and future Data Disk technology for
user-supported (wearable) computing applications.

                                 KEY SUPPLIERS

     The Company has entered into design, production, supply and support
agreements with many companies in the USA and overseas for, and in support of,
its products. They include Fujitsu, Sony Digital Products, Hitachi, Shimadzu,
JAE, Toshiba, NEC, Multicosm, IBM, Hokubu Tsushin, the SBS, and others (See
"Production").

     Although the Company believes there are multiple sources for many parts and
components, the Company currently depends heavily on its suppliers. While
management believes that the Company could adapt to any supply interruptions,
such occurrences could necessitate changes in product design or assembly methods
for the Mobile Assistant Series and cause the Company to experience temporary
delays or interruptions in supply while such changes are incorporated. Further,
because the order time for certain components may range up to approximately four
months, the Company also could experience delays or interruptions in supply in
the event the Company is required to find a new supplier for any of these
components. Any disruptions in supply of necessary parts and components from the
Company's key suppliers could have a material adverse effect on the Company's
results of operations. Any future shortage or limited allocation of components
for the Company's products could have a material adverse effect on the Company.

                                   PRODUCTION

     The Company commenced fullscale production of the MA IV in the quarter
ended December 31, 1998. The Company has manufacturing agreements with Sony
Digital Products, a subsidiary of Sony Corporation based in Nagano, Japan, and
Hokubu Tsushin for the manufacture of the MA IV. Shimadzu Corporation, a
supplier of head-mounted displays and other commercial technology products based
in Kyoto, Japan, has

                                        9
<PAGE>   10

developed and manufactured a color HMD for use with the MA IV. Most of the parts
and components for the Mobile Assistant are existing PC components that are
available in high quantity from multiple vendors.

                                   WARRANTIES

     The Company currently provides customers with warranty terms that are
competitive with those of the local market. In the U.S., the warranty is
generally one year for parts and six months for labor. Warranty services for the
MA IV is an integrated offering by several vendors. Our distribution partners
are generally responsible for user and software support. The Company currently
provides call center support internally but intends to outsource its call-center
support to a third party service firm.

                                  COMPETITION

     Several other companies are engaged in the manufacture and development of
body-mounted or hand-held computing systems, which can also compete with the
Mobile Assistant Series, including CDI, Teltronics, Inc. (a subsidiary of
Interactive Solutions Inc.), ViA Inc., Texas Microsystems, Telxon, Symbol,
Norand, Raytheon and others. The Company believes that as the markets for mobile
computing and communications converge, that its competitors will consist of
these companies as well as companies that offer mobile computing devices with
wireless communications capabilities and from companies that offer wireless
communications devices with computing capabilities. Companies with mobile
computing devices that are adding wireless communications capabilities include
Palm, Inc., a subsidiary of 3 Com, and manufacturers of notebook and handheld
computers such as Fujitsu, Mitsubishi, Toshiba, Compaq, and Sharp. Companies
with wireless communications devices that offer computing capabilities include
Motorola, Nokia, and Ericsson. Some of these devices are manufactured by major
domestic and foreign computer manufacturers which possess far more resources
than the Company and can be expected to compete vigorously with the Company for
the market in which the Mobile Assistant Series is directed. There can be no
assurance the Company will be able to compete successfully against its
competitors, or competing products, or that the competitive pressures faced by
the Company will not adversely affect its financial performance. However, the
Company believes that the entry into the market for wearable PCs by reputable,
large computer and communications manufacturers will accelerate the validation
of the market for wearable PCs. In addition, the Company believes that its
intellectual property and patent position is such that the Company is in a
strong position to command royalties from such companies.

                             INTELLECTUAL PROPERTY

     The Company relies on a combination of patent, trade secret, copyright and
trademark laws and contractual restrictions to establish and protect its
proprietary rights. The Company has entered into confidentiality and invention
assignment agreements with its employees, and enters into non-disclosure
agreements with its suppliers, VARs, OEMs and actual and potential customers to
limit access to and disclosure of its proprietary information. The Company has
registered a number of trademarks on the Principal Register of the United States
Patent and Trademark Office ("Patent Office"), including its Mobile Assistant
and Xybernaut trademarks, and with the patent and trademark offices in several
other countries.

     In addition, the Company has a total of 25 patent applications in the
United States, with thirteen patents granted and twelve patents pending, and
over 450 corresponding applications granted or pending in over 26 countries
outside the United States, for a total of over 470 patent applications granted
or pending worldwide. Of the patents granted in the United States, four are
design patents that cover a specific design of a wearable system or its
components and the remaining nine are utility patents that cover the concepts in
the patents regardless of specific execution or design. The Company believes
that these patents are a valuable asset of the Company and will present
significant opportunities for royalty revenues in the future. The most
significant utility patents for the Company are described below. All inventions
made by employees of the Company, including those described below, are assigned
to the Company by agreement with the employee upon the initiation of employment
with the Company. The Company retains full title to these patents regardless of
the

                                       10

inventor's employment status with the Company. The sections in quotations below
are taken directly from the relevant patents. Complete detail on the patents can
be found on the U.S. Patent Office website at http://www.uspto.gov, then
searching by patent number or by "Xybernaut."

     U.S. PATENT 5,305,244, "HANDS-FREE, USER-SUPPORTED PORTABLE
COMPUTERS."  The application was made on April 6, 1992 and the patent was issued
on April 19, 1994. This patent describes "A compact, self-contained computing
apparatus is provided which is completely supported by a user for hands-free
retrieval and display of information for the user." This patent has been
successfully upheld in two challenges to the validity of the patent
(re-examination) at the Patent Office that were initiated by a competitor of the
Company.

     U.S. PATENT 5,844,824, "HANDS-FREE PORTABLE COMPUTER AND SYSTEM."  The
original application was made on October 2, 1995 and the patent was issued on
December 1, 1998. This patent describes "a body-worn, hands-free computer
system. The system does not rely upon a keyboard input or activation apparatus
but rather has various activation means all of which are hands-free. The system
can be used with other systems, other system components and communication
apparatus. Also, various components of the present system can be body worn or
placed in a disconnected location if desired." Specifically, this patent covers:

     - A NUMBER OF HANDS-FREE ACTIVATION MEANS, including speech, eye-tracking,
       head tracking, arm tracking, muscle and brain-wave activation;

     - WIRELESS COMMUNICATIONS AND COMPUTING, "wherein said computer apparatus
       has means for communicating and interacting with a communication means
       selected from the group consisting of cellular telephones, hard line
       telephones, infrared transceivers, two-way radio means and mixtures
       thereof;"

     - A VARIETY OF MODES OF OPERATION, from having the display, computer and
       activation means in one housing worn by the user, to having a number of
       users with head-mounted displays with a wireless connection to a single
       computer to form a local area network for workgroups;

     - WIRELESS NETWORKING AND INTERNET ACCESS, "It goes without saying that the
       mobile computer of this invention may be interfaced with or used in
       connection with any desired computer local networks such as Novel, Banyan
       or Arcnet or wide area networks such as "Internet' or the like;"

     - INTEGRATED VOICE/DATA OPERATION, "This [feature] allows for the passing
       of voice input signals from the apparatus of this invention through to
       the telephone system while maintaining voice-activated computer control
       of the telephone system. The interface may be integrated within the
       computer apparatus of this invention, attached to it during manufacture
       or user installed. This approach provides seamless switching between
       voice and data transmission and reception between one or more distant
       locations without distracting from the task being performed by the
       individual using the computer apparatus of the present invention;"

     - DIFFERENT TYPES OF PROCESSOR, "It will be appreciated by those of
       ordinary skill in the art that while an Intel 80386 or faster processor
       is preferred, any other central processor or microprocessor, either

       available presently or in the future;"

     - VIRTUAL REALITY APPLICATIONS, "While the preferred display screen is a
       single screen positioned in front of the left or right eye, a binocular,
       head-mounted display (HMD) having two or more screens can be used. This
       can be immersive (all top and side visions obscured so that the user can
       only see the images on the screens) or as part of the user's vision so
       that the user can look over or under the displays. Such devices have
       utility in the new technology of virtual reality or where stereoscopic
       viewing is needed to relate to the displayed information;"

     - FULL VIDEO CAPABILITIES, including remote teleconferencing: "Video Camera

       units that would perform activities or sense and monitor a patient's
       bodily status and function for the patient in a hands-free environment."

     U.S. PATENT 5,948,047, "DETACHABLE COMPUTER STRUCTURE."  The original
application was made on August 29, 1996 and the patent was issued on September
7, 1999. U.S. PATENT 5,999,952, "CORE COMPUTER UNIT." The original application
was made on January 20, 1998 and the patent was issued on December 7, 1999. U.S.
PATENT 6,029,183, "TRANSFERABLE CORE COMPUTER." The original application was
made on August 15, 1997 and the patent was issued on February 22, 2000.

     These three issued patents, and others pending, cover various aspects of
what the Company calls "core computing," or the use of a small device about the
size of a current PDA that contains a processor, non-volatile storage and other
components that docks into various enclosures to function as a notebook,
desktop, home, wearable computing/communicating device, automobile or embedded
computer. This core computer allows the user to always have his or her preferred
operating system, graphical user interface, applications software and data
available in almost any environment without the need to synchronize these items
among multiple computers in multiple locations. For example, whether the user is
answering email at home, in the office, in a car or while walking around, the
same email settings, wireless communication settings, address book, past emails
and email strings would be available in each of these environments. A field
technician would be able to keep technical information, communication settings,
daily work logging, etc., available whether the technician was on top of a
telephone pole, in a service truck, in the office, or at home.

     The Company believes that users will increasingly demand a single device to
handle their range of computing, communications, and task needs such as
schedules, telephone numbers, or to-do lists, rather than having separate PDAs,
notebook computers, cellular telephones, pagers, etc., to handle these
functions. By separating the computing functions from the input and output
functions, the core computing concept allows for standard cores to be
mass-produced at a low cost, and allows the functionality of the enclosure to be
tailored to the environment, applications requirements and the desired price
level. The rate of obsolescence is substantially higher for the elements within
the core, namely the processor and the nonvolatile storage, than for the
input/output devices, such as monitors, CD-ROMs, keyboards, and modems. This
approach allows the user to upgrade the processor and storage capabilities of
the computer without having to replace other functions typically integrated
within a desktop or a laptop computer today. In this matter, the core computer
becomes a truly "personal computer" for the user.

     The Company believes that initially the core computer will interface with
the enclosures by means of physical contact. Eventually, the Company believes
that the interface with the enclosures and the user's environment will be done
by radio frequency signals, such as those proposed for the Bluetooth wireless
standard developed to connect computing devices. These developments position the
Company with the products and intellectual property to be at the forefront of
the pervasive computing movement, in which the users have the ability to
constantly interact with their environment and represents the complete
convergence of communications and computing capabilities.

     For example, travelers could insert their core computer into an enclosure
in the bed stand of their hotel room upon arrival. The core would then interact
with the hotel computer so the room can be set to the preferred temperature
setting, order room service, and arrange for a wake-up call. In addition, the
room computer could ask if the traveler wanted the next day's plane reservations
confirmed, then check the airline's web site to confirm the flight and the
traveler's reservations. The core could then obtain directions to the locations
of scheduled meetings in the area and interact with the hotel computer system to
provide a list of recommended restaurants, entertainment events, or sporting
events for the traveler. The traveler might then take the core in a rented
enclosure with an integrated global positioning system and take a guided tour of
the
                                       12
<PAGE>   13

city, directing the traveler to the location of preferred restaurants or
entertainment events, provide history or background, or allow the traveler to
view listings of companies within the city, sorted by various criteria, to
develop potential list of sales prospects.

     In this pervasive computing concept, the Company believes that users will
demand a consistent interface regardless of whether the user is computing,
communicating, or interacting with the environment. The various interfaces,
settings, and limits on Web sites or graphical content that can be presented by
the variety of devices on the market today present a hindrance to use as the
user must constantly adjust settings for the different environments, or carry
multiple devices to handle different situations. The Company believes that the
wearable and core concepts alleviate this problem by providing a single device
that can be used to accommodate all of the user's requirements.

     The Company has notified several of its competitors of the existence of one
or more of its patents, which the Company's counsel believes may have been
infringed. The Company intends to take any and all appropriate measures,
including legal action, necessary to maintain and enforce its rights under the
patents held by the Company and to recover any damages suffered as a result of
any alleged infringement.

     Most of the Company's revenue for the year ended December 31, 1999 and 1998
was derived from the sale of products included within the scope of the patents.

     Notwithstanding the foregoing, there can be no assurance that the Company's
pending patent applications will issue as patents, that any issued patent will
provide the Company with significant competitive advantages or that challenges
will not be instituted against the validity or enforceability of any patent held
by the Company. The cost of litigation to uphold the validity and prevent
infringement of patents can be substantial. There also can be no assurance that
others will not independently develop similar or more advanced products, design
patentable alternatives to the Company's products or duplicate the Company's
trade secrets. The Company may in some cases be required to obtain licenses from
third-parties or to redesign its products or processes to avoid infringement.
The Company also relies on trade secrets and proprietary technology and enters
into confidentiality agreements with its employees and consultants. The Company
has implemented a trade secret management program to further protect the
Company's trade secrets and proprietary information. There can be no assurance
that the obligation to maintain the confidentiality of such trade secrets or
proprietary information will not be breached by employees or consultants or that
the Company's trade secrets or proprietary technology will not otherwise become
known or be independently developed by competitors in such a manner that the
Company has no practical recourse.

                            RESEARCH AND DEVELOPMENT

     Research and development expenditures for the years ended December 31, 1999
and 1998 and were $2,462,752 and $2,870,808 respectively. These expenditures
consist primarily of personnel engaged in the research and design of new
hardware products, test components, consulting fees, equipment and purchased
software costs required to conduct the Company's development activities.

     The Company expects that as it shifts more of the applied research to its
partners, and focuses instead on basic research to and the establishment of
product requirements and specifications, it will not require increases in
research and development expenditures commensurate with the level of new product
development and introduction. During the second half of fiscal 1999, research
and development expenditures declined over the first half of fiscal 1999 and
last half of fiscal 1998, as the MA IV was finalized during those earlier
periods in design and development activities for the Company's next generation
of products had not yet begun.

                           EMPLOYEES AND CONSULTANTS

     As of December 31, 1999, the Company had 78 full-time and 13 part-time
employees, and had consulting arrangements with eight individuals or firms for
advice and assistance on selected technical and business issues. Of the
Company's full-time employees, 5 are executive officers, 20 are technical and
administrative support employees, 18 are engaged in research and development,
and 35 are engaged in sales, marketing and

                                       13
<PAGE>   14

customer service. None of the Company's employees are represented by a labor
organization and management believes that the Company's relations with its
employees are good. Company employees manage the affairs of the Company and
direct the Company's partners for manufacturing, sales and customer support.

lease requires monthly rent of $10,936.

ITEM 3.  LEGAL PROCEEDINGS.

     On March 19, 1998, Matrix Corporation ("Matrix") filed a complaint against
the Company in the United States District Court, Eastern District of North
Carolina, alleging that: Matrix has been damaged by a purported breach of an
agreement between the two companies concluded in December 1997 (the "December
Agreement"), and that the Company should return all goods shipped by Matrix
under both the December Agreement and a prior agreement concluded in June 1997
(the "June Agreement"). The Company and its legal counsel filed a counterclaim
against Matrix stating that Matrix failed to perform to the requirements of both
the June Agreement and the December Agreement and that the Company has been
damaged by this failure to perform. The trial for the case was completed in
August 1999 and on September 22, 1999 the District Court rendered a judgment
against the Company. The Company paid approximately $875,000 to Matrix in the
quarter ending December 31, 1999, in full settlement of this legal proceeding
and, as part of the settlement, received approximately 150 systems and
components for its 133P model. At December 31, 1999, the Company accrued
$150,000 in legal fees incurred in connection with this lawsuit. These amounts
are included in the Company's general and administrative expenses in the related
periods.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

ITEM 6.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

                                    OVERVIEW

     The Company was founded in October 1990 and commenced operations in
November 1992 to develop, manufacture and sell wearable computing and
communications systems solutions and software. In July 1996, the Company
successfully completed the IPO of its common stock and warrants. The Company's
stock is currently traded on the NASDAQ SmallCap Market and the Company intends
to apply for listing on the Nadaq National Market in the near future.

                                       15

     The first commercial product in the Mobile Assistant series of wearable
PCs, the Mobile Assistant I, was introduced in 1994 and used "486" based
technology. The Mobile Assistant II was introduced in January 1997 and used
"586" based technology. The Mobile Assistant III used a Pentium processor
running at 133 MHz and was introduced during the third quarter of 1997. In the
fourth quarter of 1998, the Company commenced production of the fourth system in
this product development program, the Mobile Assistant IV ("MA IV"), which uses
a Pentium chipset known as the "Tillamook" that runs at 233 MHz.

     Additional software products are being developed and are planned for
development for use on the Mobile Assistant and other personal computers. The
Company currently offers linkAssist(TM), a software product which provides a
"windows" style graphical user interface with speech navigation that allows data
stored in almost any format, such as commonly-used word processing, spreadsheet,
data base, graphics or media files, to be linked to virtually any application
without altering the original data.

     Since inception, the Company has financed its operations primarily through
private and public sales of equity securities, borrowings under notes and loans,
and to a lesser extent, cash generated from operations. In 1999 and 1998, the
Company received net proceeds of $19,272,368 and $10,426,712, respectively, from
the public and private placements of its equity securities and $3,039,315 and
$1,250,000, respectively, from borrowings under notes and loans.

     Historically, the Company has derived its revenues from sales of the Mobile
Assistant Series, consulting services related to the Mobile Assistant, licensing
of its intellectual property and application software for the Mobile Assistant
and other computer platforms. During the years ended December 31, 1999 and 1998,
the Company derived substantially all of its revenues from sales of the Mobile
Assistant. In the future, the Company expects to derive additional revenues from
licensing, services, and the sale of software and additional optional components
of the Mobile Assistant Series. Cost of sales include the cost of components for
the Mobile Assistant Series, inventory obsolescence charges, amortization of
tooling costs and fulfillment and shipping costs.

     The Company has incurred operating losses throughout 1999 and expects such
losses to continue in the near term as it expands its product development and
marketing capabilities. At December 31, 1999, the Company had an accumulated
deficit of $48,140,128. The achievement of profitability is primarily dependent
upon the continued development and commercial acceptance of the Company's
products, the successful management of the business and management's ability to
strategically focus the Company. There can be no assurance as to whether or when
profitable operations will occur. In addition, the Company is experiencing
negative cash flow from operations and it is expected that it will continue to
experience negative cash flows through 2000 and potentially thereafter.

     The Company's independent accountant's report on its financial statements
as of and for the years ended December 31, 1999 and 1998 contains an explanatory
paragraph that the Company's historical operating losses and limited capital
resources raise substantial doubt about its ability to continue as a going
concern. The Company may require substantial additional funds in the future, and
there can be no assurance that any independent accountant's report on the
Company's future financial statements will not include a similar explanatory
paragraph if the Company is unable to raise sufficient funds or generate
sufficient cash flow from operations to cover the costs of its operations.

     The Company intends to continue to make expenditures on research and
development of additional hardware and software products. Research and
development activities consist primarily of personnel engaged in the research
and design of new products and test components, consulting fees and equipment
costs required to conduct the Company's development activities. Software
development costs are expensed as incurred until technological feasibility is
established in accordance with Statement of Financial Accounting Standards No.
86, "Accounting for the Costs of Computer Software to be Sold, Leased or
Otherwise Marketed," after which any additional costs are capitalized until the
software is ready for release. Through December 31, 1999 the costs eligible for
capitalization under SFAS 86 were immaterial and were not capitalized. Research
and development expenses for the years ended December 31, 1999 and 1998 were
$2,462,752 and $2,870,808, respectively, none of which were capitalized.

                                       16

     The Company's consolidated financial statements, for all periods presented,
include the results of operations of Tech Virginia, a wholly-owned subsidiary
that supplies software and consulting services to the United States government
and others, Xybernaut K.K., the wholly-owned operating subsidiary in Japan and
Xybernaut GmbH, the wholly-owned operating subsidiary in Germany. The
consolidated financial statements contain eliminations for all material
transactions among the Company and these wholly-owned subsidiaries for all
periods presented.

     The Company's consolidated financial statements contain a provision for
income tax expense operations outside the United States. Subject to realization,
the Company has generated net operating losses in the U.S. that can be used to
offset taxable operating income in the future. The Company's future operations,
if profitable, will be subject to income tax expense not previously incurred by
the Company (see Note 9 to Consolidated Financial Statements). At December 31,
1999, the Company had approximately $43,665,000 and $1,100,000 of net operating
loss carry forwards for U.S. federal and foreign income tax purposes,
respectively. The U.S. losses begin to expire in 2010 and the losses from
foreign operations do not expire. The use of the U.S. carryforwards may be
limited in any one year under Internal Revenue Code Section 382 if significant
ownership changes occur.

YEAR 2000 ISSUE

     The year 2000 issue is the result of computer programs being written using
two digits rather than four to define the applicable year. Any of the Company's
computer programs that have date-sensitive software may recognize a date using
"00" as the year 1900 rather than the year 2000. This could result in a system
failure or miscalculations causing disruptions of operations, including, a
temporary inability to process transactions, send invoices, or engage in similar
normal business activities.

     The Company utilized both internal and external resources to test,
reprogram or replace, as needed, the computing and communications hardware and
software for year 2000 modifications. Based on this evaluation, modifications
were made to the Company's computer system and it was determined that these
systems will properly utilize dates beyond December 31, 1999. As such, the
Company is compliant with the year 2000 issue. As a result of the testing, the
old phone system was determined not to be year 2000 compliant. In December 1999
the existing phone system was replaced with one that provides enhanced
capabilities and is year 2000 compliant. The cost to purchase and install the
new phone system was approximately $75,000. Outside of the phone system, the
cost of testing and modifying the Company's computer systems to obtain year 2000
compliance was less than $10,000 in the aggregate.

     The Company has contacted all of its significant suppliers and large
customers to determine the possible effect on our operations of their inability
or failure to remediate their own year 2000 issues. While the Company does not
believe that our significant suppliers and customers have potential problems
with the year 2000 issue, there can be no guarantee that the systems of our
customers and suppliers were timely converted successfully to avoid the year
2000 issue, or that any failure to successfully avoid the year 2000 issue by
another company, or a conversion that is incompatible with our systems, would
not have material adverse effect on our operations. The Company does not believe
that it has exposure to contingencies related to the year 2000 issue for the
Company's products. The Company did not experience any significant product or
system failures or miscalculations related to the year 2000 issue on or since
January 1, 2000.

     The estimates of the date of completion and the cost of the Company's year
2000 project are based on the best available estimates, which were derived
utilizing numerous assumptions of future events, including the continued
availability of certain resources, third party modification plans and other
factors. The final costs and results of the Company's year 2000 project could
differ materially from estimates due to the lack of availability and cost of
personnel trained in this area, the ability to locate and correct all relevant
computer codes, and similar uncertainties.

</TABLE>

              YEARS ENDED DECEMBER 31, 1999 AND DECEMBER 31, 1998

     REVENUES.  Revenues for the year ended December 31, 1999 were $3,340,272,
an increase of $2,464,712, or 281.5%, compared to $875,560 for the year ended
December 31, 1998. Product revenues for the year ended December 31, 1999 were
$3,301,899, an increase of $2,428,313 or 278.0%, compared to $873,586 for the
corresponding period in 1998. This increase was related to the higher unit sales
of the MA IV in 1999 relative to the unit sales of predecessor models in the
prior year. Consulting, licensing and other revenues for the year ended December
31, 1999 were $38,373, an increase of $36,399, or 1,843.9%, compared to $1,974
for the corresponding period in 1998, resulting from consulting revenues
realized by the Company's Professional Services Group, which was formed during
fiscal 1999.

     COST OF SALES.  The cost of sales for the year ended December 31, 1999 was
$2,854,456, an increase of $580,001 or 25.5%, compared to $2,274,455 for the
year ended December 31, 1998. In 1999, the Company recognized charges of
approximately $304,000 related to the amortization of capitalized tooling costs
for products sold. Additionally, in 1998, the Company recognized charges of
approximately $455,000 related to the write-off of certain capitalized tooling
costs related to the 133P Systems. In 1999 and 1998, the Company recognized
charges to decrease the carrying value of inventory by $120,000 and $770,557,
respectively, to reflect the loss of value of older products and technologies.
The cost of sales as a percentage of revenues for the year ended December 31,
1999 was 72.8% before related charges and was 85.5% after related charges,
compared to 119.8% before related charges and 259.8% after related charges for
the year ended December 31, 1999.

     SALES AND MARKETING EXPENSES.  Sales and marketing expenses for the year
ended December 31, 1999 was $8,377,811, an increase of $3,889,315 or 86.7%,
compared to $4,488,496 for the year ended December 31, 1998. The increase
resulted primarily from increases in consulting expenses related to additional
marketing programs to support the launch of the MA IV, personnel and
infrastructure costs related to support sales, marketing and customer service,
and expenses related to sales activities at the Company's subsidiaries in Japan
and Germany.

                                       18
<PAGE>   19

     GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
for the year ended December 31, 1999 were $6,469,922, an increase of $2,083,023
or 47.5%, compared to $4,386,899 for the year ended December 31, 1998. This
increase was related to legal settlements and related fees in 1999 of
$1,700,463, an increase of $1,215,651, compared to $484,813 in 1998, as well as
administrative expenses related to the increased development and sales activity
related to the MA IV and the establishment and staffing of operations in Japan
and Germany.

     RESEARCH AND DEVELOPMENT EXPENSES.  Research and development expenses for
the year ended December 31, 1999 were $2,462,752, a decrease of $408,056, or
14.2%, compared to $2,870,808 for the year ended December 31, 1998. This
decrease was related to the higher level of development expenditures during 1998
related to the MA IV and the substantial completion of these development
activities by the first quarter of fiscal 1999.

     INTEREST AND OTHER INCOME, NET.  Other income for the year ended December
31, 1999 was $78,095, an increase of $44,485, or 132.4%, compared to $33,610 for
the year ended December 31, 1998. This increase is primarily the result of
interest and other miscellaneous income from the Company's subsidiaries, which
were formed in 1999.

     PROVISION FOR INCOME TAXES.  The Company has accrued $29,223 for an income
tax provision in 1999 related to income earned by the Company's foreign
subsidiaries. The Company's U.S. operations had a net loss in 1999 and,
therefore, no provision for U.S. income taxes was made.

     DIVIDEND ON CONVERTIBLE PREFERRED STOCK, DEEMED DIVIDEND ACCRETION ON
CONVERTIBLE PREFERRED STOCK. For the year ended December 31, 1999, the amount of
dividends on preferred stock was $311,714, an increase of $252,411 or 425.6%,
compared to $59,303 in 1998. In accordance with the Emerging Issues Task Force
report from the Securities and Exchange Commission titled "Accounting for the
Issuance of Convertible Preferred Stock and Debt Securities with a Nondetachable
Conversion Feature," the value of the beneficial conversion feature on the
Company's convertible preferred stock issuances was recognized during the
appropriate periods. Additional paid-in capital is reduced by the amount of
accretion and preferred stock is increased by the amount of accretion, resulting
in no impact on the overall amount of stockholders' equity. The amount of this
accretion for the year ended December 31, 1999 was $1,507,376, an increase of
$599,887 or 66.1%, compared to $907,489 in 1998. The dividends and accretion for
the year ended December 31, 1999 related to the Series C, Series D and Series E
Convertible Preferred Stock and for the year ended December 31, 1998 related to
the Series A, Series B and Series C Convertible Preferred Stock.

     NET LOSS ATTRIBUTABLE TO HOLDERS OF COMMON STOCK.  As a result of the
factors described above, the net loss attributable to holders of common stock
for the year ended December 31, 1999 was $18,594,887 an increase of $4,516,607
or 32.1% compared to $14,078,280 for the year ended December 31, 1998.

                        LIQUIDITY AND CAPITAL RESOURCES

     From its inception until the completion of the IPO, the Company financed
its operations through the private sale of its securities, vendor credit,
short-term loans received from management, stockholders and others. During and
subsequent to the IPO, the Company has financed its operations from public and
private sales of its common and preferred stock, borrowings from financial
institutions and management, proceeds from the exercise of warrants and sales of
its products and services.

     On July 18, 1996, the Company completed its IPO and sold 2,415,000 Units at
a price of $5.50 per Unit. Each Unit consisted of one share of common stock and
one warrant to purchase a share of common stock at $9.00 (the "Unit"). Gross
proceeds from the sale of the Units were $13,282,500 and net proceeds after
expenses were $10,842,487.

     On April 13, 1998, the Company entered into an Equity Line of Credit
Agreement (the "Equity Line Agreement") with a private investor. Under the terms
of the Equity Line Agreement, the Company issued 840,124 shares of common stock
at a price per share of $1.27 per share and obtained the right to require the
investor to purchase an additional $10,000,000 worth of common stock at 90% of
the Company's common stock market price (the "Put Rights"). Pursuant to the
terms of the Equity Line Agreement, the Company issued warrants to purchase a
total of 60,000 shares of common stock at a price per share ranging from $1.76
to $2.81, issued 50,000 shares of common stock which could not be traded prior
to April 13, 1999 and paid $60,000 in cash. Upon exercise of a Put Right, the
Company was required to pay issuance costs of approximately 5.5% of the gross
proceeds in cash and issue shares of common stock equal to 5% of the number of
shares issued in the transaction.

     On May 22, 1998, the Company issued 375 shares of Series C Convertible
Preferred Stock (the "Series C Preferred Stock") for gross proceeds of $375,000
and 110,294 shares of common stock for additional gross proceeds of $375,000. As

     In June 1998, the Company completed a $1,000,000 private placement of
common stock in which 153,846 restricted shares, as defined in Rule 144
promulgated under the Securities Act, were issued at a price of $6.50 per share.

     In June 1998, the Company amended the Equity Line Agreement and exercised a
Put Right in the aggregate principal amount of $3,000,000. In connection with
such action, the Company issued 545,454 shares of common stock which were
subject to restrictions on resale during a nine-month period which has
subsequently lapsed. In addition, the Company issued five-year warrants to
purchase up to 300,000 shares of common stock at a price of $5.25 per share. The
amendment contained certain repricing features which, as a result of market
fluctuations in the Company's common stock, required the Company to issue an
additional 94,004 shares of its common stock without receiving additional
compensation. The Company has no further obligation to issue additional shares
related to these repricing features.

     In October 1998, the Company entered into a financing agreement with an
investor pursuant to which the Company sold $2,600,000 of common stock to the
investor during the period from October 8, 1998 to November 12, 1998. The
Company issued 593,201 shares of common stock at prices ranging from $4.04 to
$5.72 under this financing agreement. In addition, the Company issued three
warrants to purchase up to 12,500 shares of common stock each, at prices of
$9.09, $9.58 and $13.05 per share, respectively. These warrants are exercisable
at any time starting six months after the closing and ending five years after
closing. The placement agent for this transaction received a cash fee of 6%.

investor pursuant to which the Company sold $1,595,000 of common stock to the
investor. The Company issued 290,000 shares of common stock at $5.50 per share
under this financing agreement. Such shares were subject to repricing under
certain circumstances. Subsequently the Company issued an additional 150,000
shares upon the occurrence of certain repricing events.

     On December 17, 1998, the Company borrowed $1,250,000 from two financial
institutions. The maturity date of the debt was January 29, 1999 and interest
was at 12% per annum. On January 29, 1999, the Company

                                       20
<PAGE>   21

exercised separate Put Rights under the Equity Line Agreement. In connection
with such Put Rights, the Company issued 841,356 shares of common stock at
prices ranging from $4.08 to $4.46, repaid the $1,250,000 borrowed from the two
financial institutions and received proceeds of $2,110,000. In addition, the
Company issued a warrant to purchase 100,000 shares of common stock at an
exercise price of $6.00 per share and a warrant to purchase 100,000 shares of
common stock at an exercise price of $5.50 per share.

     On March 10, 1999, the Company issued the first tranche of 5,000 shares of
its Series D Convertible Preferred Stock (the "Series D Preferred Stock") for
gross proceeds of $5,000,000. The Company issued an additional 5,000 shares of
Series D Preferred Stock for gross proceeds of $5,000,000 following the
effectiveness of a registration statement covering the resale of the common
stock issuable upon conversion of the Series D Preferred Stock. In connection
with these issuances, the investors received warrants to purchase 20 shares of
common stock for each share of Series D Preferred Stock purchased. The warrants
have an exercise price of $6.09 per share and a term of three years. The Series
D Preferred Stock had a 5% cumulative dividend which is payable, in cash or
through the issuance of common stock, upon the conversion of the Series D
Preferred Stock into common stock. The Series D Preferred Stock may be converted
into shares of common stock by dividing the dollar amount of Series D Preferred
Stock outstanding by the lesser of 100% of the average of the three lowest
closing bids for the common stock during the twenty trading days prior to
conversion or $4.88, the closing bid price of the common stock on the trading
day immediately preceding the closing date of this private placement. The
Company may redeem the Series D Preferred Stock at any time for a premium to
face value that varies depending on the timing of redemption. In connection with
this private placement, the Company issued an additional 500 shares of Series D
Preferred Stock to a finder. As of December 31, 1999, holders of the Series D
Preferred Stock had converted 6,000 shares into 4,059,399 shares of common
stock, which included payment of all accrued dividends on these 6,000 shares of
Series D Preferred Stock. Additionally, during the fourth quarter of 1999, the
Company received notices from the investors to convert 4,000 shares of Series D
Preferred Stock into common stock. In January 2000, the Company converted these
4,000 shares of Series D Preferred Stock, along with related dividends, into
4,039,033 shares of common stock. Subsequent to these conversions, 500 shares of
Series D Preferred Stock were issued and outstanding.

     On May 12, 1999, the Company issued 2,000 shares of Series E Convertible
Preferred Stock (the "Series E Preferred Stock") for gross proceeds of
$2,000,000. In connection with this issuance, the investor received warrants to
purchase a total of 50,000 shares of common stock. The warrants have an exercise
price of $4.65 per share and a term of three years. The Series E Preferred Stock
has a 5% cumulative dividend which is payable, in cash or through the issuance
of common stock, upon the conversion of the Series E Preferred Stock. The
Company may redeem the Series E Preferred Stock at any time at a premium to face
value that varies depending on the timing of the redemption, as long as the
price of the common stock is above certain levels. Holders of the Series E
Preferred Stock may convert these securities into shares of common stock at the
lesser of 94% of the average of the three lowest closing bids for the common
stock during the twenty trading days prior to conversion, or $3.72, the closing
bid price of the common stock on the trading day immediately preceding the
closing date of this private placement. In connection with this private
placement, the Company issued an additional 100 shares of Series E Preferred
Stock were issued to a finder. As of December 31, 1999, the Series E Preferred
Stock investor had converted all of its 2,000 shares of Series E Preferred
Stock, along with related dividends, into 1,627,481 shares of common stock.

     On various dates during 1999, the Company borrowed $583,500 from several
officers of the Company pursuant to non-interest bearing promissory notes or
agreements. All of these borrowings had been repaid at December 31, 1999 except
for $10,000, which was repaid in February 2000.

     In August 1999, the Company entered into a financing agreement with a
lender under which the Company receives 80% of an identified accounts receivable
balance upon presentation to the lender of certain documentation supporting the
underlying sale. The Company receives the remaining 20%, net of a fee paid to
the lender, upon collection by the lender of the original accounts receivable
balance. The lender has recourse to the Company for any uncollected accounts
receivable balances. The Company paid $60,000 in initial placement fees
associated with this facility, all of which was amortized during 1999. During
the year ended

                                       21
<PAGE>   22

December 31, 1999, the Company received $456,315 in proceeds and incurred $9,698
in interest expense related to this facility. The Company owed $24,254 on this
facility at December 31, 1999.

     On September 21, 1999, the Company completed a $100,000 private placement
of common stock in which 135,000 restricted shares, as defined in Rule 144
promulgated under the Securities Act, were issued.

     During October 1999 through December 1999, the Company borrowed $1,000,000
from an investor pursuant to a secured promissory note. In connection with this
borrowing, the Company issued warrants to purchase 1,000,000 shares of its
common stock at $1.00 per share. On December 31, 1999, the cashless conversion
of these warrants into 1,000,000 shares of the Company's common stock was used
as consideration to fully repay the loan.

     During October 1999 through December 1999, the Company issued 545,000
shares of its common stock to investors who exercised warrants granted in
connection with previous financings for proceeds of $838,513.

     On November 19, 1999, the Company completed a $3,000,000 private placement
of common stock in which 1,000,000 shares were issued.

     On December 2, 1999, the Company entered into a financing facility with IBM
Global Finance (the "IBM Facility"). Borrowings under the IBM Facility are
secured by the Company's equipment, inventory and accounts receivable balances.
The Company paid $60,000 in initial placement fees, which are being amortized
over the six-month period ending May 31, 2000. Under the terms of the facility,
the Company borrowed $1,000,000 under a term loan and was extended a $3,000,000
credit line to finance customer purchases upon presentation to the lender of
certain documentation supporting the underlying sales. The borrowing under the
term loan accrues interest at the prime rate (8.5% at December 31, 1999) plus
2.5% per annum and is to be repaid in three equal installments in February,
April and June, 2000. Borrowings under the credit line accrue interest at up to
the prime rate plus 2.75%, depending on certain characteristics of the
underlying Company sales being financed such as the type of customer and the age
of the accounts receivable balance. The Company owed $1,000,000 at December 31,
1999 and incurred $9,167 in interest expense during 1999 associated with the IBM
Facility.

     Subsequent to December 31, 1999, the Company has raised approximately
$13,187,000 through the issuance of common stock, borrowings, and the exercise
of warrants granted in connection with previous financings.

     For the year ended December 31, 1999, the Company's operating activities
used cash of $15,803,023. This was primarily the result of a $16,775,797 net
loss and cash used by inventory of $3,989,991, offset by a net increase in
accounts payable and accrued expenses of $4,028,612 and depreciation and
amortization of $1,409,249. Cash used in investing activities for the year ended
December 31, 1999 was $2,236,684 which included $959,073 for the acquisition of
property and equipment, $349,250 related to obtaining and maintaining patents,
$120,000 in capitalized loan costs and $808,545 in capitalized tooling costs.
Proceeds from the Company's financing activities for the year ended December 31,
1999 were $19,056,622, which primarily consisted of $11,418,621 from the
issuance of the Company's Series D and Series E Preferred Stock, net of related
fees, $6,009,834 from the issuance of the Company's common stock, $1,838,513
from the exercise of warrants, and $3,039,315 of proceeds from notes and loans,
offset by payments on notes and loans totaling $3,255,061. As a result of the
above, cash and cash equivalents on hand as of December 31, 1999 was $2,031,143,
an increase of $1,106,494 from the $924,629 of cash on hand as of December 31,
1998.

     For the year ended December 31, 1998, the Company's operating activities
used cash of $10,699,000. This was primarily the result of a $13,111,488 net
loss and a net increase in inventories of $835,795. These were offset by a net
increase in accounts payable and accrued expenses of $1,242,766, a non-cash
obsolescence inventory charge of $770,557, depreciation and amortization of
$503,143 and a non-cash charge for tooling costs of $455,449. Cash used in
investing activities for the year ended December 31, 1998 was $985,899, which
included $448,744 in capitalized tooling costs, $313,109 related to obtaining
and maintaining patents and $256,358 for the acquisition of property and
equipment. Proceeds from the Company's financing activities for the year ended
December 31, 1998 were $11,657,182 which primarily consisted of $9,186,659 from
the issuance of common stock, $1,240,053 from the issuance of the Company's
Series B and Series C Preferred Stock, net of related fees, and $1,250,000 of
proceeds from notes and loans. As a result of the above, cash and
                                       22
<PAGE>   23

cash equivalents on hand as of December 31, 1998 was $924,649, a decrease of
$27,717 from the $952,366 of cash on hand as of December 31, 1997.

     At December 31, 1999, the Company had informal agreements with several of
its suppliers to take shipments of additional inventory of parts and components
during the first half of 2000. While the timing and amount of these shipments
may be adjusted, the total amount of inventory and related payment under these
agreements could be approximately as much as $1,500,000 to $2,000,000.

     The Company anticipates that its working capital requirements and operating
expenses will increase as the Company expands production and sales of the Mobile
Assistant Series, expands its full sales, service and marketing functions, and
develops the support structure for these activities. The timing of increases in
personnel and other expenses, the amount of working capital consumed by
operations, marketing and rollout expenses for the Mobile Assistant Series, and
competitive pressures on gross margins will impact the magnitude and timing of
the Company's cash requirements. Management is currently exploring financing
alternatives to supplement the Company's cash position. Potential sources of
additional financing include private equity financings, mergers, strategic
investments, strategic partnerships or various forms of debt financings. If
additional funds are raised by the Company through the issuance of equity
securities, the percentage of ownership of the then current stockholders of the
Company will be reduced. The Company's management believes that the combination
of cash on hand, operating cash flow, and outside funding will provide
sufficient liquidity to meet the Company's cash requirements until at least
March 2001. However, there can be no assurance that the Company can or will
obtain sufficient funds from operations or from closing additional financings on
terms acceptable to the Company.

     The Company's independent accountant's report on its financial statements
as of and for the years ended December 31, 1999 and 1998 contains an explanatory
paragraph that the Company's historical operating losses and limited capital
resources raise substantial doubt about its ability to continue as a going
concern. The Company may require substantial additional funds in the future, and
there can be no assurance that any independent accountant's report on the
Company's future financial statements will not include a similar explanatory
paragraph if the Company is unable to raise sufficient funds or generate
sufficient cash from operations to cover the costs of its operations.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and
Stockholders of Xybernaut Corporation

     We have audited the accompanying consolidated balance sheets of Xybernaut
Corporation as of December 31, 1999 and 1998, and the related consolidated
statements of operations, stockholders' equity, and cash flows for the years
then ended. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

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

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Xybernaut Corporation as of
December 31, 1999 and 1998, and the results of its operations and its cash flows
for the years then ended in conformity with generally accepted accounting
principles.

     The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 1 to the
financial statements, the Company has incurred recurring losses from operations
and will require additional capital to fund its operations. These matters raise
substantial doubt about the Company's ability to continue as a going concern.
Management's plans in regard to these matters are also described in Note 1. The
financial statements do not include any adjustments that might result from the
outcome of this uncertainty.

                             XYBERNAUT CORPORATION

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. BUSINESS AND FINANCING

  THE COMPANY

     Xybernaut Corporation (the "Company") was incorporated in Virginia as
Contemporary Products & Services, Inc. in October 1990 and changed its name to
Computer Products & Services, Inc. in November 1992. In April 1996, the Company
merged with Xybernaut Corporation, a Delaware corporation, in order to change
its name and reincorporate in Delaware. On July 18, 1996, the Company completed
its Initial Public Offering ("IPO"). Since the commencement of operations in
November 1992, the Company has engaged in the research, development and
commercialization of hardware and software products for wearable computing and
communications. The Company's current mobile computing product is the Mobile
Assistant IV model (the "MA IV(R)"), which is a full-function, body-worn,
voice-controlled computer with a body-worn video display. Additional hardware
and software products are planned for development and use on the Mobile
Assistant series and subsequent proprietary products.

  FINANCING

     The Company has incurred significant recurring losses from operations since
inception and will require additional capital to fund its operations and meet
its ongoing obligations for 2000 and potentially beyond. Management believes
they will be successful in their efforts to obtain such financing and subsequent
to year-end has raised approximately $13,187,000 (see Note 13). There can be no
assurance that the Company will not incur additional losses or will not require
significant amounts of additional capital. The accompanying consolidated
financial statements have been prepared assuming the Company will continue as a
going concern. If the Company is unable to obtain sufficient additional
financing, it will be required to reduce discretionary spending in order to
maintain its operations at a reduced level. Management believes that it will be
able to reduce discretionary spending if required. The accompanying financial
statements do not include any adjustments that might result from the outcome of
these uncertainties.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  PRINCIPLES OF CONSOLIDATION

     The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries: Xybernaut GmbH (Boblingen, Germany),
Xybernaut K.K. (Yokohoma, Japan) and Tech Virginia (Fairfax, Virginia). All
significant intercompany accounts and transactions have been eliminated in the
consolidation. Net gains and losses resulting from foreign exchange transactions
have not been material.

  USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS

     The preparation of 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. Actual results could differ from those estimates.

  CASH AND CASH EQUIVALENTS

     The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.

  INVENTORY

     Inventory consists primarily of component parts held for resale and
allocated tooling costs and is comprised principally of finished goods.
Inventory is stated at the lower of cost or market, cost being

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED:
determined on a first-in, first-out basis. Management periodically assesses the
need to provide for obsolescence of inventory and adjusts carrying values to
their net realizable value when required. As of December 31, 1999 and 1998, the
allowance to reduce inventory balances to net realizable value was $120,000 and
$770,557, respectively. The reserve at December 31, 1999 represents the
Company's estimate of the loss of value of certain of the older peripherals and
components of the MA IV. In the event that sales do not materialize, an
adjustment may be necessary to write down the carrying value of inventory. The
reserve at December 31, 1998 represents the full reduction of all inventory
amounts related to the Company's products prior generations of products.

  PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost and are depreciated on a
straight-line basis over the estimated useful lives of the assets, as follows:

<TABLE>
<S>                                                           <C>
Furniture and fixtures......................................    5 years
Equipment...................................................  3-5 years
Leasehold improvements......................................    3 years
Demonstration units.........................................    1 year
</TABLE>

     Expenditures for maintenance and repairs are expensed directly to the
appropriate operating account as incurred. Expenditures determined to represent
additions and betterments are capitalized.

  TOOLING COSTS

     Capitalized tooling costs consist of payments made to third-party vendors
for reimbursement of their products and services that are used in the design and
manufacturing of the Company's proprietary products. Tooling costs are amortized
into cost of sales expense based upon the ratio of units sold in a given period
to total units expected to be produced and sold. In 1998, the Company recognized
charges of approximately $455,000 related to the write-off of certain
capitalized tooling costs related to the Company's products prior to the MA IV.

  SOFTWARE DEVELOPMENT COSTS

     Software development costs are included in research and development and are
expensed as incurred. Statement of Financial Accounting Standards No. 86
requires the capitalization of certain software development costs once
technological feasibility is established, which the Company defines as the
completion of a working model. The capitalized cost is then amortized on a
straight-line basis over the estimated product life, or on the ratio of current
revenues to total projected product revenues, whichever is greater. To date, the
period between achieving technological feasibility and the general availability
of such software has been short and software development costs qualifying for
capitalization have not been significant. Accordingly, the Company has not
capitalized any software development costs. Since the Company is currently in
the planning and development phase for software toolkits, no costs have been
capitalized to date.

  PATENT COSTS

     Patent costs consist of legal fees, filing fees and other direct costs
incurred in obtaining patents and are amortized on a straight-line basis over a
five-year period and are presented as general and administrative expenses in the
accompanying consolidated statements of operations. Amortization expense related
to the patents was $206,701 and $136,906 during 1999 and 1998, respectively.
Costs associated with the upkeep and maintenance of existing patents are
expensed as incurred.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED:
  START-UP COSTS

     The Company expenses start-up and organization costs as incurred in
accordance with Statement of Position 98-5, "Reporting on Costs of Start-Up
Activities."

  IMPAIRMENT OF LONG-LIVED ASSETS

     Management of the Company monitors the carrying value of long-lived assets
for potential impairment on an on-going basis. Potential impairment would be
determined by comparing the carrying value of these assets with their related,
expected future net cash flows. Should the sum of the related, expected future
net cash flows be less than the carrying value, management would determine
whether an impairment loss should be recognized. An impairment loss would be
measured by the amount by which the carrying value of the asset exceeds the
future discounted cash flows. No such impairment losses were recorded during
1999 or 1998.

  REVENUE RECOGNITION AND WARRANTIES

     The Company recognizes revenues upon shipment to end-users pursuant to a
valid purchase order ("sell-to accounting"). Shipments to distributors are
accounted for using "sell-through accounting," under which revenue is recognized
when the distributor ships to an end-user, until such time as an adequate
history of shipments and returns from distributors can be developed to allow for
revenue to be recognized upon shipment offset by an allowance for returns.
Shipments to distributors are treated as revenue upon shipment only if shipped
pursuant to a separate purchase order that stipulates that the products are for
demonstration or testing by the distributor and that the obligation to pay is
binding and not subject to contingencies.

     The Company generally provides a one-year warranty on parts and a six-month
warranty on labor. A provision for estimated future warranty costs is recorded
at the time of shipment. However, the Company's suppliers for the significant
components of the MA IV, including the computing unit, flat panel display, head
mounted display, and batteries, provide the Company with similar warranties. The
Company recorded warranty expense of $36,204 and $59,678 during 1999 and 1998,
respectively, and had a warranty reserve of $100,781 and $64,577 at December 31,
1999 and 1998, respectively.

  RESEARCH AND DEVELOPMENT PROGRAMS

     Research and development costs are charged to operations as incurred,
including the cost of components purchased for testing and product development
that are saleable but are intended for development work only.

  INCOME TAXES

     Deferred income tax assets and liabilities are computed annually for
differences between the financial statement and income tax bases of assets and
liabilities that will result in taxable or deductible amounts in the future.
Such deferred income tax asset and liability computations are based on enacted
tax laws and rates applicable to periods in which the differences are expected
to affect taxable income. Income tax expense is the tax payable or refundable
for the period plus or minus the change during the period in deferred income tax
assets and liabilities. The provision for income taxes in 1999 results from the
operations of the Company's international subsidiaries.

  NET LOSS PER SHARE

     Basic earnings (or loss) per share is based on the weighted average number
of outstanding shares of common stock. Diluted earnings per share adjusts the
weighted average for the potential dilution that could occur if stock options,
warrants or other convertible securities were exercised or converted into common
stock.

                                       F-8
<PAGE>   33
                             XYBERNAUT CORPORATION

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED:
For all periods presented herein, diluted earnings per share is the same as
basic earnings per share for the Company because the effects of such items were
anti-dilutive given the losses incurred in such periods.

  ISSUANCE OF EQUITY SECURITIES FOR SERVICES

     Periodically, the Company issues shares of common stock and options to
purchase shares of common stock to vendors and consultants in return for goods
or services. These transactions are recorded at either the fair value of the
securities issued or at the fair value of goods received or services performed,
whichever is more reliably measured.

  ESCROWED SHARES

     Escrowed shares are considered issued and outstanding and reported as such
on the combined balance sheets until their cancellation. At December 31, 1999,
all escrowed shares had been cancelled. Since the Company has reported losses,
the loss per share for the Company is calculated using outstanding shares less
shares held in escrow to avoid antidilution. Therefore, the cancellation of
shares from escrow does not affect the reported losses per share.

  FAIR VALUE OF FINANCIAL INSTRUMENTS

     The carrying amounts of financial instruments including cash and cash
equivalents, accounts receivable and accounts payable approximated fair value as
of December 31, 1999 and 1998, because of the relatively short maturity of these
instruments. The carrying value of the notes and loans payable approximated fair
value as of December 31, 1999 and 1998, based upon market prices for the same or
similar debt issues.

  FOREIGN CURRENCY TRANSLATION

     Assets and liabilities of the Company's foreign subsidiaries are translated
at the exchange rate on the balance sheet date. Translation adjustments
resulting from this process are charged or credited to equity. Revenues and
expenses are translated at average exchange rates prevailing during the year.
Gains and losses on foreign currency transactions are included in nonoperating
revenues and expenses.

  RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities." In 1999, the
required implementation date of SFAS No. 133 was delayed to fiscal years
beginning after June 15, 2000. SFAS 133 requires that all derivative instruments
be recorded on the balance sheet at their fair value. Changes in the fair value
of derivatives are recorded each period in current earnings or other
comprehensive income, depending on whether a derivative is designated as part of
a hedge transaction and, if it is, the type of hedge transaction. Currently the
Company does not utilize derivative instruments, but may elect to do so to hedge
foreign currency exposure if such exposure becomes significant. The adoption of
SFAS 133 is not expected to have a significant effect on the Company's results
of operations or its financial position. The Company will adopt SFAS 133 for the
year ending December 31, 2001.

  RECLASSIFICATIONS

     Certain 1998 balances and disclosures have been reclassified to conform to
the 1999 presentation.

5. NOTES PAYABLE

     On December 17, 1998, the Company borrowed $1,250,000 from two financial
institutions. The maturity date of the debt was January 29, 1999 and interest
was at 12% per annum. On January 29, 1999, the Company repaid the principal and
accrued interest through the issuance of common stock.

     On various dates during 1999, the Company borrowed a total of $583,000 from
several officers of the Company pursuant to non-interest bearing promissory
notes or agreements. All of these borrowings had been repaid at December 31,
1999 except for $10,000, which was repaid in February 2000.

     In August 1999, the Company entered into a financing agreement with a
lender under which the Company receives 80% of an accounts receivable balance
upon presentation to the lender of certain documentation supporting the
underlying sale. The Company receives the remaining 20%, net of a fee paid to
the lender, upon collection by the lender of the original accounts receivable
balance. The lender has recourse to the Company for any uncollected accounts
receivable balance. The Company paid $60,000 in initial placement fees
associated with this facility, all of which was amortized during 1999. During
the year ended December 31, 1999, the Company received $456,315 in proceeds and

5. NOTES PAYABLE, CONTINUED:
     Between October 1999 and December 1999, the Company borrowed $1,000,000
from an investor pursuant to a secured promissory note. On December 31, 1999,
the cashless conversion of warrants issued in connection with this borrowing was
used as consideration to fully repay the loan.

     On December 2, 1999, the Company entered into a financing facility with IBM
Global Finance (the "IBM Facility"). Borrowings under the IBM Facility are
secured by the Company's equipment, inventory and accounts receivable balances.
The Company paid $60,000 in initial placement fees, which are being amortized
over the six-month period ending May 31, 2000. Under the terms of the facility,
the Company borrowed $1,000,000 under a term loan and was extended a $3,000,000
credit line to finance customer purchases upon presentation to the lender of
certain documentation supporting the underlying sales. The borrowing under the
term loan accrues interest at up to the prime rate (8.5% at December 31, 1999)
plus 2.5% per annum and is to be repaid in three equal installments in February,
April and June, 2000. Borrowings under the credit line accrue interest up to the
prime rate plus 2.75%, depending on certain specifics of the underlying Company
sales being financed, such as the type of customer and the age of the accounts
receivable balance. The Company owed $1,000,000 at December 31, 1999 and
incurred $9,167 in interest expense during 1999 associated with the IBM
Facility.

common stock, upon the conversion of the Series D Preferred Stock into common
stock. The Series D Preferred Stock may be converted into shares of common stock
by dividing the dollar amount of Series D Preferred Stock outstanding by the
lesser of 100% of the average of the three lowest closing bids for the common
stock during the twenty trading days prior to conversion or $4.88, the closing
bid price of the common stock on the trading day immediately preceding the
closing date of this private placement. The Company may redeem the Series D
Preferred Stock at any time for a premium to face value that varies depending on
the timing of redemption. In connection with this private placement, the Company
issued an additional 500 shares of Series D Preferred Stock to a finder. As of
December 31, 1999, holders of the Series D Preferred Stock had converted 6,000
shares into 4,059,399 shares of common stock, which included payment of all

Additionally, during the fourth quarter of 1999, the Company received notices
from the investors to convert 4,000 shares of Series D Preferred Stock into
common stock. In January 2000, the Company converted these 4,000 shares of
Series D Preferred Stock, along with related dividends, into 4,039,033 shares of
common stock. Subsequent to these conversions, 500 shares of Series D Preferred
Stock remain issued and outstanding.

     On May 12, 1999, the Company issued 2,000 shares of Series E Preferred
Stock for gross proceeds of $2,000,000. In connection with this issuance, the
investor received warrants to purchase a total of 50,000 shares of common stock.
The warrants had an exercise price of $4.65 per share and a term of three years.
The Series E Preferred Stock has a 5% cumulative dividend which is payable, in
cash or through the issuance of common stock, upon the conversion of the Series
E Preferred Stock. The Company may redeem the Series E Preferred Stock at any
time at a premium to face value that varies depending on the timing of the
redemption, as long as the price of the common stock is above certain levels.
Holders of the Series E Preferred Stock may convert these securities into shares
of common stock at the lesser of 94% of the average of the three lowest closing
bids for the common stock during the twenty trading days prior to conversion, or
$3.72, the closing bid price of the common stock on the trading day immediately
preceding the closing date of this private placement. In connection with this
private placement, the Company issued an additional 100 shares of Series E
Preferred Stock to a finder. As of December 31, 1999, the Series E Preferred
Stock investor had converted all of its 2,000 shares of Series E Preferred

common stock into which its various convertible preferred stock issuances can be
converted except for the 500 shares of Series D Preferred Stock and the 100
shares of Series E Preferred Stock which were issued to finders in connection
with the respective private placements. As of January 2000, the SEC has declared
effective all such registration statements.

     The Company's preferred stock issues have included nondetachable conversion
features that are considered to be "in the money" at the date of issuance (a
"beneficial conversion feature"). The beneficial conversion was recognized as a
return to the preferred stockholders over the minimum period in which the
preferred stockholders could realize the maximum beneficial conversion. As a
result of the accumulated deficit, the value of the preferred stock was not
allocated between par value and additional paid-in capital and the accretion of
the value allocated to the beneficial conversion on the preferred stock and the
related dividends is recorded against additional paid-in capital. At December
31, 1999, all of the value associated with the beneficial conversion features
has been fully accreted against additional paid-in capital.

  COMMON STOCK

     On April 13, 1998, the Company entered into an Equity Line of Credit
Agreement (the "Equity Line Agreement") with a private investor. Under the terms
of the Equity Line Agreement, the Company issued 840,124 shares of common stock
at $1.27 per share and obtained the right to require the investor to purchase an
additional $10,000,000 worth of common stock at 90% of the Company's common
stock market price (the "Put Rights"). Upon exercise of a Put Right, the Company
was required to pay issuance costs of approximately 5.5% of the gross proceeds
in cash and issue shares of common stock equal to 5% of the number of shares
issued in the transaction. Pursuant to the terms of the agreement, the Company
issued warrants to purchase a total of 60,000 shares of common stock at a price
per share ranging from $1.76 to $2.81, issued 50,000 shares of common stock
which could not be traded prior to April 13, 1999 and paid $60,000 in cash.

     In July 1998, the Company amended the Equity Line Agreement to allow for
the sale of 545,454 shares of common stock for $5.50 per share and issued
five-year warrants to purchase up to 300,000 shares of common stock at a price
of $5.25 per share. The amendment contained certain repricing features which, as
a result of market fluctuations in the Company's common stock, required the
Company to issue an additional 94,004 shares of common stock without receiving
additional compensation. The Company has no further obligation to issue
additional shares related to these repricing features.

     On May 22, 1998, concurrent with the sale of the Company's Series C
Preferred Stock, the Company issued 110,294 shares of common stock for $3.40 per
share.

     In January 1999, the Company exercised additional Put Rights in which it
issued 841,356 shares of common stock at prices ranging from $4.08 to $4.46 for
cash proceeds of $2,110,000 and for use as consideration for the repayment of
certain notes payable. In addition, the Company issued a warrant to purchase
100,000 shares of common stock at an exercise price of $5.50 per share and a
warrant to purchase 100,000 shares of common stock at an exercise price of $6.00
per share.

     In November 1998, the Company sold 290,000 shares of common stock for $5.50
per share to a private investor. The terms of the purchase agreement allowed for
an adjustment to the purchase price per share based on market fluctuations in
the Company's common stock. Based on events in December 1998, the Company was
required to issue an additional 150,000 shares of common stock to this investor
without receiving additional compensation. The Company has no further obligation
to issue additional shares related to these repricing features.

of these warrants into 1,000,000 shares of the Company's common stock was used
as consideration to fully repay the loan.

     In the quarter ended December 1999, the Company issued 545,000 shares of
its common stock to investors who exercised warrants granted in connection with
previous financings for proceeds of $838,513.

     Exclusive of the expired warrants issued in connection with the Company's
IPO and the conversion of debentures during 1996 and 1997 discussed above, the
Company has issued warrants to purchase 3,510,560 shares of its common stock in
connection with the Company's various financings at prices that range from $1.00
to $18.00 per share. At December 31, 1999, the Company had warrants outstanding
to purchase 1,842,700 shares of its common stock at prices that range from $1.50
to $18.00 per share. Subsequent to year-end, certain of these warrants were
exercised at an average price of $4.51 per share, resulting in the issuance of
1,565,200 shares of common stock.

  ESCROWED SHARES

     As a condition to the Company's IPO, a representative of the several
underwriters required certain of the Company's stockholders to deposit a total
of 1,800,000 shares of common stock (the "Escrowed Shares") in escrow pursuant
to an escrow agreement.

     The Escrowed Shares were to be released over a three-year period in the
event the Company's gross revenues and earnings (loss) per share for the
12-month periods ending September 30, 1997, 1998 and 1999 equaled or exceeded
certain per share targets or if the Company's stock price exceeded a certain per
share target price. If such targets were not met, certain amounts of the
Escrowed Shares were to be returned to the Company for each period and canceled.

6. STOCKHOLDERS' EQUITY, CONTINUED:
     The Company did not meet the targets for escrow release for the periods
ending September 30, 1997, 1998 or 1999. As a result, 300,000, 750,000 and
750,000 shares, respectively, were canceled from the escrow pool and returned to
the Company, resulting in a reduction of 2.1%, 3.6% and 3.1% of the outstanding
shares of common stock on each of the cancellations, respectively.

     Since the Company has reported losses, the loss per share for the Company
is calculated using outstanding shares less shares held in escrow to avoid
anti-dilution. Therefore, the cancellation of shares from escrow does not affect
the reported loss per share.

7. STOCK OPTIONS

     On April 18, 1996, the Board of Directors approved, effective January 1,
1996, the Company's 1996 Omnibus Stock Incentive Plan (the "1996 Plan"). At the
annual meeting of stockholders on August 28, 1997, the Company's stockholders
approved the 1997 Stock Incentive Plan (the "1997 Plan"). At the annual meeting
of stockholders on December 28, 1999, the Company's stockholders approved the
1999 Stock Incentive Plan (the "1999 Plan").

     Under these plans, the Company may grant incentive stock options,
non-qualified stock options, stock appreciation rights and shares of common
stock to officers, directors, employees and others. The Company's stock options
are generally exercisable in five equal annual installments beginning one year
after the date of grant. Under the terms of these plans, no stock option may be
granted at less than the fair market value of the Company's common stock on the
date of grant.

     The 1996 Plan, the 1997 Plan and the 1999 Plan authorize the issuance of
650,000, 1,650,000 and 3,000,000 shares of the Company's common stock,
respectively. At December 31, 1999, 650,000, 1,573,466, and 2,537,845 of the
shares authorized under the 1996 Plan, the 1997 Plan and the 1999 Plan,
respectively, are outstanding.

7. STOCK OPTIONS, CONTINUED:
     The Company complies with the disclosure-only provisions of Statement of
Financial Accounting Standards No. 123, "Accounting for Stock Based
Compensation." In accordance with the provisions of SFAS No. 123, the Company
applies APB Opinion 25 and related interpretations in accounting for its plans
and, accordingly, does not recognize compensation expense.

     Had compensation expense for the Company's plan been determined based on
the fair value at the grant date for plan awards consistent with the provisions
of SFAS No. 123, the Company's net loss and net loss per common and common
equivalent shares outstanding would have been the pro forma amounts indicated
below:

     The weighted-average fair values of each option at the date of grant for
1999 and 1998 was $1.53 and $0.67, respectively, and were estimated on the date
of grant using the Black-Scholes option-pricing model with the following
weighted-average assumptions used in 1999 and 1998: dividend yield of 0%;
expected volatility of 70% in 1999 and 60% in 1998; risk-free interest rate of
5.49% in 1999 and 5.20% in 1998; and expected lives of 3 years.

8. SEGMENT AND ENTERPRISE WIDE REPORTING

     The Company has adopted SFAS No. 131, "Disclosures About Segments of an
Enterprise and Related Information," in the fiscal year ended December 31, 1999.
SFAS No. 131 requires certain financial and supplementary information to be
disclosed on an annual and interim basis of each reportable segment of an
enterprise. SFAS No. 131 also establishes standards for related disclosures
about products and services, geographic areas and major customers. Operating
segments are defined as components of an enterprise about which separate
discrete financial information is evaluated regularly by the chief operating
decision maker or decision making group, in deciding how to allocate resources
and assess performance. The financial information disclosed herein, materially
represents all of the financial information related to the Company's principal
operating segments as a provider of wearable computers. The Company established
foreign subsidiaries in both Germany and Japan in January 1999.

     Revenues by geographical destination as a percentage of total revenues for
the year ended December 31, 1999 are as follows:

9. SIGNIFICANT VENDOR

     One manufacturer currently supplies a significant portion of the Company's
production parts and components. Management believes other manufacturers could
provide the parts and components on similar terms. However, a delay in supply of
the necessary parts and components, as a result of a change in supplier, could
have a material adverse effect on the Company's results of operations.

10. INCOME TAXES

     For the years ended December 31, 1999 and 1998 no income tax benefit has
been provided because the losses could not be carried back and realization of
the benefit of the net operating losses carried forward was not assured. In
1999, the Company recognized approximately $29,000 in income tax expense related
to foreign operations.

     At December 31, 1999, the Company had approximately $43,665,000 and
$1,100,000 of net operating loss carryforwards for U.S. federal and foreign
income tax purposes, respectively. The U.S. losses begin to expire in 2010 and
the losses from foreign operations do not expire. The use of the U.S.
carryforwards may be limited in any one year under Internal Revenue Code Section
382 if significant ownership changes occur.

Agreement"), and that the Company should return all goods shipped by Matrix
under both the December Agreement and a prior agreement concluded in June 1997

THESE SECURITIES AND THE SECURITIES ISSUABLE UPON THEIR EXERCISE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933 AND MAY NOT BE TRANSFERRED UNLESS
COVERED BY AN EFFECTIVE REGISTRATION STATEMENT UNDER SAID ACT, A "NO ACTION"
LETTER FROM THE SECURITIES AND EXCHANGE COMMISSION WITH RESPECT TO SUCH
TRANSFER, A TRANSFER MEETING THE REQUIREMENTS OF RULE 144 OF THE SECURITIES AND
EXCHANGE COMMISSION, OR AN OPINION OF COUNSEL SATISFACTORY TO THE ISSUER TO THE
EFFECT THAT ANY SUCH TRANSFER IS EXEMPT FROM SUCH REGISTRATION.

                             XYBERNAUT CORPORATION

                         COMMON STOCK PURCHASE WARRANT

         1.       Issuance. In consideration of good and valuable
consideration, the receipt of which is hereby acknowledged by Xybernaut
Corporation, a Delaware corporation (the "Company"), Crystalite Investments
Ltd., or registered assigns (the "Holder") is hereby granted the right to
purchase at any time until 5:00 P.M., New York City time, on October 1, 2004
(the "Expiration Date"), Five Hundred Thousand (500,000) fully paid and
nonassessable shares of the Company's Common Stock, par value $.01 per share
(the "Common Stock") at an initial exercise price of $1.01 per share (the
"Exercise Price"), subject to further adjustment as set forth in Section 6
hereof.

         2.       Exercise of Warrants. This Warrant is exercisable in whole or
in part at the Exercise Price per share of Common Stock payable hereunder,
payable in cash or by certified or official bank check, or by "cashless
exercise", by means of tendering this Warrant Certificate to the Company to
receive a number of shares of Common Stock equal in Market Value to the
difference between the Market Value of the shares of Common Stock issuable upon
exercise of this Warrant and the total cash exercise price thereof. Upon
surrender of this Warrant Certificate with the annexed Notice of Exercise Form
duly executed, together with payment of the Exercise Price for the shares of
Common Stock purchased, the Holder shall be entitled to receive a certificate
or certificates for the shares of Common Stock so purchased. For the purposes
of this Section 2, "Market Value" shall be an amount equal to the average
closing bid price of a share of Common Stock for the ten (10) days preceding
the Company's receipt of the Notice of Exercise Form duly executed multiplied
by the number of shares of Common Stock to be issued upon surrender of this
Warrant Certificate.

         3.       Reservation of Shares. The Company hereby agrees that at all
times during the term of this Warrant there shall be reserved for issuance upon
exercise of this Warrant such number of shares of its Common Stock as shall be
required for issuance upon exercise of this Warrant (the "Warrant Shares").

         4.       Mutilation or Loss of Warrant. Upon receipt by the Company of
evidence satisfactory to it of the loss, theft, destruction or mutilation of
this Warrant, and (in the case of

<PAGE>   2

loss, theft or destruction) receipt of reasonably satisfactory indemnification,
and (in the case of mutilation) upon surrender and cancellation of this
Warrant, the Company will execute and deliver a new Warrant of like tenor and
date and any such lost, stolen, destroyed or mutilated Warrant shall thereupon
become void.

         5.       Rights of the Holder. The Holder shall not, by virtue hereof,
be entitled to any rights of a stockholder in the Company, either at law or
equity, and the rights of the Holder are limited to those expressed in this
Warrant and are not enforceable against the Company except to the extent set
forth herein.

         6.       Protection Against Dilution.

                  6.1      Adjustment Mechanism. If an adjustment of the
Exercise Price is required pursuant to this Section 6, the Holder shall be
entitled to purchase such number of additional shares of Common Stock as will
cause (i) the total number of shares of Common Stock Holder is entitled to
purchase pursuant to this Warrant, multiplied by (ii) the adjusted purchase
price per share, to equal (iii) the dollar amount of the total number of shares
of Common Stock Holder is entitled to purchase before adjustment multiplied by
the total purchase price before adjustment.

                  6.2      Capital Adjustments. In case of any stock split or
reverse stock split, stock dividend, reclassification of the Common Stock,
recapitalization, merger or consolidation, or like capital adjustment affecting
the Common Stock of the Company, the provisions of this Section 6 shall be
applied as if such capital adjustment event had occurred immediately prior to
the date of this Warrant and the original purchase price had been fairly
allocated to the stock resulting from such capital adjustment; and in other
respects the provisions of this Section shall be applied in a fair, equitable
and reasonable manner so as to give effect, as nearly as may be, to the
purposes hereof. A rights offering to stockholders shall be deemed a stock
dividend to the extent of the bargain purchase element of the rights.

         7.       Transfer to Comply with the Securities Act; Registration
Rights.

         (a) This Warrant has not been registered under the Securities Act of
1933, as amended, (the "Act") and has been issued to the Holder for investment
and not with a view to the distribution of either the Warrant or the Warrant
Shares. Neither this Warrant nor any of the Warrant Shares or any other
security issued or issuable upon exercise of this Warrant may be sold,
transferred, pledged or hypothecated in the absence of an effective
registration statement under the Act relating to such security or an opinion of
counsel satisfactory to the Company that registration is not required under the
Act. Each certificate for the Warrant, the Warrant Shares and any other
security issued or issuable upon exercise of this Warrant shall contain a
legend on

                                       2

<PAGE>   3

the face thereof, in form and substance satisfactory to counsel for the
Company, setting forth the restrictions on transfer contained in this Section.

         (b) The Company hereby grants to the Holder piggyback registration
rights with respect to the Warrant Shares. In the event the Company is filing a
Registration Statement for itself or on behalf of any of its shareholders, the
Company shall notify the Holder in writing reasonably in advance of such filing
(but at least five business days) and give the Holder the opportunity to
include all or any party of the Warrant Shares (whether or not previously
issued, to the extent permissible under the Act or any regulation promulgated
thereunder. Upon the Holder's notification that the Holder desires to have all
or any portion of the Warrant Shares included in such registration, the Company
shall, at no cost or expense to the Holder, include or cause to be included in
such registration statement the Warrant Shares so identified by the Holder.

         (c) In addition to the registration rights referred to in the
preceding provisions of Section (b), effective after the expiration of the
effectiveness of the Registration Statement as contemplated by the Registration
Rights Agreement, the Holder shall have demand piggy-back registration rights
with respect to the Warrant Shares then held by the Holder or then subject to
issuance upon exercise of this Warrant (collectively, the "Remaining Warrant
Shares"), subject to the conditions set forth below. If, at any time after the
Registration Statement has ceased to be effective, the Company participates
(whether voluntarily or by reason of an obligation to a third party) in the
registration of any shares of the Company's stock, the Company shall give
written notice thereof to the Holder and the Holder shall have the right,
exercisable within ten (10) business days after receipt of such notice, to
demand inclusion of all or a portion of the Holder's Remaining Warrant Shares
in such registration statement.

         8.       Notices. Any notice or other communication required or
permitted hereunder shall be in writing and shall be delivered personally,
telegraphed, telexed, sent by facsimile transmission or sent by certified,

of $1.78 per share and shall have a term of three (3) years.

               (b) In consideration of the Executive's execution and delivery of
this Agreement, upon the execution and delivery of this Agreement the Company
shall make a cash payment of $50,000 (the "Signing Bonus"). By this Agreement,
the Company confirms that its prior grant to the Executive of options to
purchase 300,000 shares of the Company's Common Stock at an exercise price equal
to the average of the closing price for the Company's Common Stock on October 1,
1999 and having a term of seven (7) years, which was ratified by the Company's
Board of Directors on December 27, 1999.

               (c) At the sole discretion of the Board of Directors of the
Company the Executive may be paid, in cash, Common Stock, options to purchase
Common Stock, Stock Appreciation Rights ("SAR's") or any combination thereof, an
annual bonus in such an amount, if any, and based upon such criteria as the
Board of Directors of the Company may from time to time consider appropriate
(the "Discretionary Bonus"). In addition, this Agreement shall confirm the prior
grant to the Executive, in recognition of the Executive's past services to the
Company, of a grant to the Executive of options to purchase 100,000 shares of
the Company's Common Stock at an exercise price equal to the closing price of
the Company's Common Stock on December 3, 1999. The options granted pursuant to
this Section 4(b) shall be vested as of the date hereof, and shall be subject to
the terms and provisions of the Company's 1997 Stock Option Plan, the Company's
1999 Stock Option Plan or any subsequently enacted stock option plan, as
applicable, except that they may be exercised in any amount at any time after
being vested until three (3) years from date of termination of employment and
shall be irrevocable during that period. Should there not be sufficient options
available or usable under said stock option Plans then, the Company will use its
best efforts to cause a new stock option plan to be adopted which will cover
such options. If no new stock option plan is adopted, the Company will grant
SAR's or make a cash payment to the Executive of substantially similar value,
within one hundred eighty (180) days from the date that it is determined that a
sufficient number of options are not available.

               (d) As additional consideration for Executive's services to the
Company hereunder, the Company shall pay Executive an annual bonus (the
"Performance Bonus"), based upon the Company's performance during the Employment
Term, commencing with the fiscal year from January 1, 2000 through December 31,
2000, and for each fiscal year during the Employment Term thereafter, if earned,
in the form of options to purchase shares of the


                                       5


<PAGE>   6
Company's Common Stock, in an amount equal to the greater of (i) one and
one-half percent (1.5%) of the Revenue Goal (as hereinafter defined), if the
Revenue Goal is attained; or (ii) two percent (2%) of the increase, if any, in
the Market Cap from January 1 through December 31 of the applicable fiscal year
during the Employment Term. For purposes hereof, the term "Revenue Goal" shall
mean eighty-five percent (85%) of the Company's revenue goal for each fiscal
year during the Employment Term occurring after the first year of the Employment
Term, as set forth in its business plan for such year; provided that for the
fiscal year from January 1, 2000 through December 31, 2000 the Revenue Goal
shall be $20,000,000. For purposes hereof, the Market Cap Test shall be based on
the average of the number of shares outstanding and closing prices for the
Company's Common Stock for the thirty (30) days ended December 31 of the
applicable year, compared to the comparable thirty (30) day period in the prior
year. The calculation of whether any Performance Bonus is due for any fiscal
year during the Employment Term occurring thereafter, as applicable, shall be
made by the Board of Directors promptly after the end of the fiscal year in
respect of the Market Cap test and upon the Company's issuance of its audited
annual financial statements in respect of the Revenue Goal test. The Performance
Bonus, if earned, shall be paid in the form of options to purchase shares of the
Company's Common Stock valued at an exercise price equal to the average of the
closing market price of the shares of the Company's Common Stock for the thirty
(30) days prior to the end of the applicable fiscal year. Any options issued in
respect of the Performance Bonus shall be subject to the terms and provisions of
the Company's 1999 Stock Option Plan or, if no shares are available under such
Plan, or any subsequently enacted stock option plan, as applicable, except that
they may be exercised in any amount, at any time after being vested until three
(3) years from date of termination of employment and are irrevocable during that
period. Should there not be sufficient options available or usable under said
Stock Option Plans, the Company will use its best efforts to cause a new stock
option plan to be adopted which will cover the options subject to the
Performance Bonus. If no new stock option plan is adopted, the Company will
grant SAR's or make a cash payment to the Executive of substantially similar
value, within one hundred eighty (180) days from the date that it is determined
that a sufficient number of options are not available.

               (e) Notwithstanding anything set forth in Section 4(c), in no
event shall the options granted to the Executive, if any, as the Performance
Bonus with respect to any fiscal year during the Employment Term exceed the
greater of (i) options exercisable into 500,000 shares of Common Stock or (ii)
1.5% of the Company's outstanding shares of capital stock.

               (f) Should there be a Change of Control of the Company or any
other transaction in which the Company is not the surviving entity during the
Employment Term, then as part of that transaction, the Company will require the
surviving entity to modify the Agreement in an equitable manner to provide the
Executive the same type of benefits that he is entitled to earn pursuant to
Section 4(c) of this Agreement.

               (g) All options granted to the Executive pursuant to the
Agreement or referred to herein, to the extent permitted by applicable law,
shall be transferable and assignable. Any


                                       6


<PAGE>   7
unvested options granted to the Executive hereunder shall fully vest upon a
Change in Control or upon a termination of this Agreement by the Executive for
Good Reason.

               Section 5. Benefits, Vacation. (a) During the Employment Term,
the Executive shall be entitled to such insurance and health and medical
benefits as are generally made available to the senior executives of the
Company, as a group, pursuant to such plans as are from time to time maintained
by the Company; provided, however, that the Executive shall be required to
comply with the conditions of coverage attendant to such plans.

               (b) During each contract year of the Employment Term, the
Executive shall be entitled to six (6) weeks of vacation. The Executive shall
take vacation at such time or times as the Executive desires, subject to the
concurrence of the Company based upon the then current business needs and
activities of the Company. Vacation shall accrue if unused during the term of
employment.

               (c) During the Employment Term, the Executive shall be eligible
to participate in the profit sharing and other benefit plans that the Company
from time to time makes available to the senior executives of the Company as a
group, subject to the terms, provisions and conditions of such plans, including,
without limitation, any vesting periods and eligibility criteria.

               (d) During the Employment Term, the Company shall pay to the
Executive a non-accountable expense allowance of $1,500 per month. In addition,
the Company shall also pay reasonable legal and estate planning expenses of
Executive in an amount not to exceed $5,000 for each calendar year during the
Employment Term. The amounts paid and/or provided for in this Section 5(d) shall
be reported by the Company on Internal Revenue Service Form 1099.

               (e) The Company agrees to maintain in full force and effect the
life insurance policy in the face amount aggregating Two Million Dollars
($2,000,000.00), which are made payable to such beneficiary or beneficiaries who
are designated by the Executive. The Company shall pay all premiums due on such
policies during the Employment Term. After the termination or expiration of the
Employment Term, at the request of the Executive, the Company shall assign such
insurance policies to the Executive.

               Section 6. Business Expenses. The Executive shall be entitled to
reimbursement for ordinary, necessary and reasonable business expenses actually
incurred by the Executive during the Employment Term in the performance of the
Executive's duties hereunder, if supported by such reasonable documentation as
may be required by the Company in accordance with the Company's policies.

               Section 7. Termination of Employment Term. (a) In the event of
the death of the Executive during the Employment Term, the Executive's
employment hereunder shall automatically terminate as of the date of death;
provided, however, that the Executive's estate or


                                       7


<PAGE>   8
legal representative, as the case may be, shall be entitled to receive, and the
Company shall pay, any accrued and unpaid Salary for a two (2) year period
following the date of death, any Performance Bonus that would be payable for the
two (2) year period in which the Executive died which are properly owing to the
Executive pursuant to Section 6 hereof.

               (b) In the event of the Executive's Incapacity, the Company may,
in its sole discretion, terminate the Executive's employment hereunder upon
written notice to the Executive; provided, however, that the Executive or the
Executive's legal representative, as the case may be, shall be entitled to
receive, and the Company shall pay, (i) any accrued and unpaid Salary for a two
(2) year period from the date of termination, less any amounts received by the
Executive under any disability insurance policy maintained by the Company; and
(ii) any Performance Bonus that would be payable for the two (2) year period
after the Executive's employment is terminated due to Incapacity and
reimbursement of business expenses which are properly owing to the Executive
pursuant to Section 6 hereof, through the date of termination; provided that in
no event shall the amount of the Performance Bonus be less than fifty percent
(50%) of what it would have been for the entire year.

               (c) The Company shall have the right to terminate the Executive's
employment under this Agreement at any time for Cause upon written notice to the
Executive. In the event the Executive's employment hereunder is terminated by
the Company for Cause, the Company shall only be obligated to pay accrued and
unpaid Salary through the date of termination and the Company shall pay any
accrued and unreimbursed business expenses which are properly owing to the
Executive pursuant to Section 6 hereof through the date of termination.

               (d) The Company shall have the right to terminate the Executive's
employment hereunder Without Cause at any time upon ten (10) days' prior written
notice to the Executive. If the Company terminates the Executive's employment
hereunder Without Cause, the Company shall (i) continue to pay Salary to the
Executive provided for hereunder for a period equal to the greater of (x) 2
years from the date of termination and (y) the remaining period of the
Employment Term and (ii) pay any unreimbursed business expenses which are
properly owing to the Executive pursuant to Section 6 hereof through the date of
termination. In addition, should the Executive's employment hereunder be
terminated Without Cause, the Company shall pay to the Executive the Performance
Bonus, if any, for the entire contract year in which the termination of the
Executive's employment with the Company hereunder occurs and for the contract
year following the year in which the termination occurred. The Executive shall
not be under any obligation to mitigate the Company's obligation pursuant to
this Section 7(d) by securing other employment or otherwise.

employment with the Company hereunder for Good Reason, upon not less than thirty
(30) days prior written notice to the Company. Should the Executive terminate

<PAGE>   9
               (f) The failure of the Company to continue the employment of the
Executive upon expiration of the entire three (3) year Employment Term shall not
be considered a termination of employment for purposes of this Agreement. The
Company's obligations with respect to the Performance Bonus for the last year of
the Employment Term, if any, shall survive the expiration of this Agreement.

               Section 8. Inventions. Any Inventions originated or conceived by
the Executive related to the Company's business, during his employment by the
Company or any Affiliate of the Company or with the use or assistance of the
facilities, materials or personnel of the Company or any Affiliate of the
Company, either solely or jointly with others, during the period of employment
with the Company or any Affiliate of the Company shall be the sole and exclusive
property of the Company. The Executive hereby irrevocably assigns and transfers
to the Company and agrees to transfer and assign to the Company all of his
right, title and interest in and to all Inventions, and to applications for
patents and patents granted upon such Inventions and to all copyrightable
material related thereto developed by the Executive or under his supervision.
The Executive agrees for himself and his heirs and personal representatives,
upon the request of the Company and at the Company's expense, to do such acts,
to execute such documents and instruments and to participate in such legal
proceedings as from time to time may be necessary or required to apply for,
secure, maintain, reissue, extend or defend the worldwide rights of the Company
in the Inventions.

               Section 9. Restrictions Respecting Competing Businesses,
Confidential Information, etc. The Executive acknowledges and agrees that by
virtue of the Executive's position and involvement with the business and affairs
of the Company, the Executive will develop substantial expertise and knowledge
with respect to all aspects of the Company's business, affairs and operations
and will have access to all significant aspects of the business and operations
of the Company and to Confidential and Proprietary Information.

               (a) The Executive hereby covenants and agrees that, during the
Employment Term and thereafter, unless otherwise authorized by the Company in
writing, the Executive shall not, directly or indirectly, under any
circumstance: (i) disclose to any other Person (other than in the regular course
of business of the Company) any Confidential and Proprietary Information, other
than pursuant to applicable law, regulation or subpoena or with the prior
written consent of the Company; (ii) act or fail to act so as to impair the
confidential or proprietary nature of any Confidential and Proprietary
Information; (iii) use any Confidential and Proprietary Information other than

cause or assist in the inception or continuation of, any such disclosure,
impairment or use of any Confidential and Proprietary Information. Following the
Employment Term, the Executive shall return all documents, records and other
items containing any Confidential and Proprietary Information to the Company
(regardless of the medium in which maintained or stored), without retaining any
copies, notes or excerpts thereof, or at the request of the Company, shall
destroy such documents, records and items (any such destruction to be certified
by the Executive to the Company in writing).

               (b) The Executive covenants and agrees that, while the Executive
is employed by the Company and for one (1) year after the Executive ceases to be
employed by the Company, if the Executive (i) voluntarily terminates his
employment with the Company for Good Reason or (ii) is terminated by the Company
for Cause, the Executive shall not, directly or indirectly, manage, operate or
control, any Competing Business or, directly or indirectly, induce or influence
any customer or other Person that has a business relationship with the Company,
or any Affiliate of the Company, to discontinue or reduce the extent of such
relationship; provided that in the case of a termination by the Executive
pursuant to clause (i) the Company at all times continues to pay the amounts
owing to the Executive pursuant to Section 7(b) hereof. For purposes of this
Agreement, the Executive shall be deemed to be directly or indirectly
interested in a business if he is engaged or interested in that business as a
stockholder, director, officer, Executive, agent, partner, individual
proprietor, consultant, advisor or otherwise, but not if the Executive's
interest is limited solely to the ownership of not more than 5% of the
securities of any class of equity securities of a corporation or other Person
whose shares are listed or admitted to trade on a national securities exchange
or are quoted on NASDAQ or a similar means if NASDAQ is no longer providing
such information.

               (c) While the Executive is employed by the Company and for one
(1) year after the Executive ceases to be an employed by the Company, the
Executive shall not, directly or indirectly, solicit to employ for himself or
others any employee of the Company or any Affiliate of the Company who was an
employee of the Company or any Affiliate of the Company as of the date of the
termination of the Executive's employment with the Company, or to solicit any
such employee to leave such employee's employment or join the employ of another,
then or at a later time; provided that the foregoing shall not apply to any
family member of the Executive who is employed by the Company or any such
Affiliate or the Executive's administrative assistant.

               (d) The parties agree that nothing in this Agreement shall be
construed to limit or negate the common law of torts, confidentiality, trade
secrets, fiduciary duty and obligations where such laws provide the Company with
any broader, further or other remedy or protection than those provided herein.

               (e) Because the breach of any of the provisions of this Section 9
will result in immediate and irreparable injury to the Company for which the
Company will not have an adequate remedy at law, the Company shall be entitled,
in addition to all other rights and remedies, to seek a degree of specific
performance of the restrictive covenants contained in this Section 9 and to a
temporary and permanent injunction enjoining such breach, without posting bond
or furnishing similar security.

               Section 10. Severability. Each term and provision of this
Agreement is severable; the invalidity, illegality or unenforceability or
modification of any term or provision of this Agreement shall not affect the
validity, legality and enforceability of the other terms and


                                       10


<PAGE>   11
provisions of this Agreement, which shall remain in full force and effect. Since
it is the desire and intent of the parties that the provisions of this Agreement
be enforced to the fullest extent permissible under the laws and public policies
applied in each jurisdiction in which enforcement is sought, should any
particular provision of this Agreement be deemed invalid, illegal or
unenforceable, the same shall be deemed reformed and amended to delete that
portion that is adjudicated to be invalid, illegal or unenforceable and the
deletion shall apply only with respect to the operation of such provision and to
the extent of such provision and, to the extent that a provision of this
Agreement would be deemed unenforceable by virtue of its scope, but may be made
enforceable by limitation thereon, each party agrees that this Agreement shall
be reformed and amended so that the same shall be enforceable to the fullest
extent permissible under the laws and public policies applied in the
jurisdiction in which enforcement is sought.

               Section 11. Assignment. This Agreement and the rights and
obligations of the parties hereto shall bind and inure to the benefit of each of
the parties hereto, the heirs, executors, administrators and legal
representatives of the Executive and the successors and permitted assigns of the
Company. Neither this Agreement nor any rights or benefits hereunder may be
assigned by the Executive or the Company without the prior written consent of
the other party hereto, except that the Company may assign any of its rights or
obligations hereunder to any other Person which purchases all or substantially
all of the common stock or assets of the Company or is the successor to the
Company by merger, consolidation or other similar transaction.

               Section 12. Amendment; Entire Agreement. This Agreement may not
be modified, amended, altered or supplemented except by a written agreement
executed by the parties hereto. This Agreement contains the entire agreement and
understanding of the parties hereto with respect to the subject matter of this
Agreement and supersedes all prior and/or contemporaneous agreements and
understandings of any kind and nature (whether written or oral) between the
parties with respect to such subject matter, all of which are merged herein.

               Section 13. Waivers. Waiver by either party of either breach of
or failure to comply with any provision of this Agreement by the other party
shall not be construed as, or constitute, a continuing waiver of such provision,
or a waiver of any other breach of, or failure to comply with, any other
provision of this Agreement, any such waiver must be in writing to be limited to
the specific matter and instance for which it is given. No waiver of any such
breach or failure or of any term or condition of this Agreement shall be
effective unless in a written instrument and signed by the waiving party and
delivered, in the manner required for notices generally, to the affected party.

                              EMPLOYMENT AGREEMENT


               EMPLOYMENT AGREEMENT dated as of January 1, 2000 (this
"Agreement"), by and between STEVEN A. NEWMAN (the "Executive"), and XYBERNAUT
CORPORATION, a Delaware Corporation (the "Company").

               WHEREAS, the Company desires to employ the Executive as the

employment with the Company in the aforementioned capacity, all upon the terms
and provisions, and subject to the conditions set forth in this Agreement.

               NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements contained herein, and other good and valuable
consideration, the receipt and legal sufficiency of which are hereby
acknowledged, the parties hereby agree as follows:

               Section 1. Definitions. As used in this Agreement the following
terms shall have the meanings set forth in this Section 1:

               (a) "Affiliate" of any Person means any stockholder or person or
entity controlling, controlled by under common control with such Person, or any
director, officer or key executive of such Person or any of their respective
relatives. For purposes of this definition, "control," when used with respect to
any Person, means the power to direct the management and policies of such
Person, directly or indirectly, whether through the ownership of voting
securities, by contract or otherwise; and the terms "controlling" and
"controlled" have meanings that correspond to the foregoing.

               (b) "Cause" shall mean (i) the Company being subjected to any
criminal liability under any applicable law as a result of any action or
inaction on the part of the Executive, which the Executive did not, at the time,
reasonably believe to be in the best interests of the Company; (ii) the
conviction or admission of the Executive of, or plea by the Executive of nolo
contendre to, a felony or crime involving moral turpitude which the Board of

               Section 4. Compensation.

               (a) In consideration of the performance of all of the duties and
obligations to be performed by the Executive hereunder, the Company agrees to
pay, and the Executive agrees to accept, for the first year of the Employment
Term a salary (the "Salary") at an annual rate of $225,000, payable in
accordance with the Company's regular payroll practices as from time to time in
effect, less all withholdings and other deductions required to be deducted in

adjusted to be at an annual rate of $225,000, any differential owing to the
Executive as a result of such adjustment shall be paid to the Executive promptly
after the execution and delivery of this Agreement. After the first year during

increased by the lesser of (i) 10% and (ii) the percentage increase, if any, in
the CPI for each year just completed measured for the entire twelve (12) month

Washington, D.C. metropolitan area prepared by the Bureau of Labor Statistics of
the U.S. Department of Labor, or if such index is not then being published, by

the parties may agree upon. By this Agreement, the Company confirms its prior
grant to the Executive, of options to purchase shares of the Company's Common
Stock in respect of a salary deferral applicable to the Executive for the period
from September 1, 1999 through December 31, 1999, on the same basis as the other
employees of the Company. Such options vest immediately upon the grant, shall
have an exercise price of $1.78 per share and shall have a term of three (3)
years.

               (b) In consideration of the Executive's execution and delivery of
this Agreement, upon the execution and delivery of this Agreement the Company
shall make a cash payment of $50,000.00 (the "Signing Bonus"). By this
Agreement, the Company confirms its prior grant to the Executive of options to
purchase 300,000 shares of the Company's Common Stock at an exercise price equal
to the closing price for the Company's Common Stock on October 1, 1999 and
having a term of seven (7) years, which was ratified by the Company's Board of
Directors on December 27, 1999.

               (c) At the sole discretion of the Board of Directors of the
Company the Executive may be paid, in cash, Common Stock, options to purchase
Common Stock, Stock Appreciation Rights ("SAR's") or any combination thereof, an
annual bonus in such an amount, if any, and based upon such criteria as the
Board of Directors of the Company may from time to time consider appropriate
(the "Discretionary Bonus"). The minimum amount of the cash portion of the
Discretionary Bonus for fiscal year 2000 shall be $100,000, which minimum amount
shall be paid within five (5) business days after the Executive's request
therefor. In addition, this Agreement shall confirm the prior grant to the
Executive's, in recognition of the Executive's past services to the Company, of
a grant to the Executive of options to purchase 100,000 shares of the Company's
Common Stock at an exercise price equal to the closing price of the Company's
Common Stock on December 3, 1999, which grant was ratified by the


                                      -5-


<PAGE>   6
Company's Board of Directors on December 27, 1999. The options granted as part
of the Discretionary Bonus shall be vested as of the date hereof, and shall be
subject to the terms and provisions of the Company's 1997 Stock Option Plan, the
Company's 1999 Stock Option Plan or any subsequently enacted stock option plan,
as applicable, except that they may be exercised in any amount at any time after
being vested until three (3) years from date of termination of employment and
shall be irrevocable during that period. Should there not be sufficient options
available or usable under said stock option Plans then, the Company will use its
best efforts to cause a new stock option plan to be adopted which will cover
such options. If no new plan is adopted, the Company will grant SAR's or make a
cash payment to the Executive of substantially similar value, within one hundred
eighty (180) days from the date that it is determined that a sufficient number
of options are not available.

               (d) As additional consideration for Executive's services to the
Company hereunder, the Company shall pay Executive an annual bonus (the
"Performance Bonus"), based upon the Company's performance during the Employment
Term, commencing with the fiscal year from January 1, 2000 through December 31,
2000, and for each fiscal year during the Employment Term thereafter, if earned,
in the form of options to purchase shares of the Company's Common Stock, in an
amount equal to the greater of (i) one and one-half percent (1.5%) of the
Revenue Goal (as hereinafter defined), if the Revenue Goal is attained; or (ii)
two percent (2%) of the increase, if any, in the Market Cap from January 1
through December 31 of the applicable fiscal year during the Employment Term.
For purposes hereof, the term "Revenue Goal" shall mean eighty-five percent
(85%) of the Company's revenue goal for each fiscal year during the Employment
Term occurring after the first year of the Employment Term, as set forth in its
business plan for such year; provided that for the fiscal year from January 1,
2000 through December 31, 2000 the Revenue Goal shall be $20,000,000. For
purposes hereof, the Market Cap Test shall be based on the average of the number
of shares outstanding and closing prices for the Company's Common Stock for the
thirty (30) days ended December 31 of the applicable year, compared to the
comparable thirty (30) day period in the prior year. The calculation of whether
any Performance Bonus is due for any fiscal year during the Employment Term
occurring thereafter, as applicable, shall be made by the Board of Directors
promptly after the end of the fiscal year in respect of the Market Cap test and
upon the Company's issuance of its audited annual financial statements in
respect of the Revenue Goal test. The Performance Bonus, if earned, shall be
paid in the form of options to purchase shares of the Company's Common Stock
valued at an exercise price equal to the average of the closing market price of
the shares of the Company's Common Stock for the thirty (30) days prior to the
end of the applicable fiscal year. Any options issued in respect of the
Performance Bonus shall be subject to the terms and provisions of the Company's
1999 Stock Option Plan or, if no shares are available under such Plan, or any
subsequently enacted stock option plan, as applicable, except that they may be
exercised in any amount, at any time after being vested until three (3) years
from date of termination of employment and are irrevocable during that period.
Should there not be sufficient options available or usable under said Stock
Option Plans, the Company will use its best efforts to cause a new stock option
plan to be adopted which will cover the options subject to the Performance
Bonus. If no new plan is adopted, the Company will grant SAR's or make a cash


                                      -6-


<PAGE>   7
payment to the Executive of substantially similar value, within one hundred
eighty (180) days from the date that it is determined that a sufficient number
of options are not available.

               (e) Notwithstanding anything set forth in this Section 4(d), in
no event shall the options granted to the Executive, if any, as the Performance
Bonus with respect to any fiscal year during the Employment Term exceed the
greater of (i) options exercisable into 500,000 shares of Common Stock or (ii)
1.5% of the Company's outstanding shares of capital stock.

               (f) Should there be a Change of Control of the Company or any
other transaction in which the Company is not the surviving entity during the
Employment Term, then as part of that transaction, the Company will require the
surviving entity to modify the Agreement in an equitable manner to provide the
Executive the same type of benefits that he is entitled to earn pursuant to
Section 4(d) of this Agreement.

               (g) All options granted to the Executive pursuant to this
Agreement or referred to herein, to the extent permitted by applicable law,
shall be transferable and assignable. Any unvested options granted to the
Executive hereunder shall fully vest upon a Change of Control or upon a
termination of this Agreement by the Executive for Good Reason.

               Section 5. Benefits, Vacation.

               (a) During the Employment Term, the Executive shall be entitled

attendant to such plans.

               (b) During each contract year of the Employment Term, the

modification of any term or provision of this Agreement shall not affect the
validity, legality and enforceability of the other terms and provisions of this

the fullest extent permissible under the laws and public policies applied in

adjudicated to be invalid, illegal or unenforceable and the deletion shall apply

provision and, to the extent that a provision of this Agreement would be deemed
unenforceable by virtue of its scope, but may be made enforceable by limitation
thereon, each party agrees that this Agreement shall be reformed and amended so

laws and public policies applied in the jurisdiction in which enforcement is
sought.

     4.   REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE BUYERS. Each of the

bankruptcy or other laws affecting the enforcement of creditors' rights
generally;

          (b)   The Buyers have received and carefully reviewed copies of the
Public Documents (as hereinafter defined). No representations or warranties have
been made to the Buyers by the Company, the officers or directors of the
Company, or any agent, employee or affiliate of any of them, except as
specifically set forth herein or as set forth in the other documents expressly
referred to herein. Each of the Buyers understands that no Federal, state, local
or foreign governmental body or regulatory authority has made any finding or
determination relating to the fairness of an investment in the Shares and that
no Federal, state, local or foreign governmental body or regulatory authority
has recommended or endorsed, or will recommend or endorse, any investment in the

information or representations made by third parties;

          (c)   Each of the Buyers understands that the Shares are being offered
and sold to it in reliance on specific provisions of Federal and state

applicable securities laws and (ii) has not offered or sold any of the Shares
and has no present intention or agreement to divide the Shares with others for
purposes of selling, offering, distributing or otherwise disposing of any of the

registration under the Securities Act, by virtue of Section 4(2) and Regulation
D promulgated under the Securities Act. Each of the Buyers understands that the
shares of Common Stock purchased



                                       -2-

<PAGE>   3

hereunder have not been, and may never be, registered under the Securities Act;
that the Shares cannot be sold, transferred, assigned, pledged or subjected to
any lien or security interest unless they are first registered under the
Securities Act and such state and other securities laws as may be applicable or
in the opinion of counsel for the Company an exemption from registration under
the Shares Act is available (and then the Shares may be sold, transferred,
assigned, pledged or subjected to a lien or security interest only in compliance
with such exemption and all applicable state and other securities laws); and
that the following legends will be placed upon the certificate for the Shares:

          "The Shares represented by this certificate have not been registered
          under the Securities Act of 1933, as amended (the "Securities Act"),
          and may not be offered for sale, sold or otherwise transferred,
          pledged or subjected to any lien or security interest, in the absence
          of an effective registration statement under the Securities Act or a
          written opinion of counsel for the Company that the Shares may be
          offered for sale, sold, transferred, pledged or subjected to a lien or
          security interest pursuant to an exemption under the Securities Act
          and such state and other securities laws as may be applicable."

financial and business matters as to be capable of evaluating the merits and
risks of an investment in the Company; and (ii) recognizes that such Buyer's
investment in the Company involves a high degree of risk; and

          (h)   Each of the Buyers is capable of evaluating the risks and merits
of an investment in the Shares by virtue of its experience as an investor and
its knowledge, experience, and sophistication in financial and business matters
and such Buyer is capable of bearing the entire loss of its investment in the
Shares.

          (i)   None of the Buyers is a registered broker-dealer or an affiliate
of a registered broker-dealer.

     5.   REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE COMPANY. The Company

<PAGE>   4

collectively with the Form 10-KSB, the "Public Documents"). The Public Documents
at the time of their filing did not include any untrue statement of a material
fact or omit to state any material fact necessary in order to make the
statements contained therein, in light of the circumstances under which they
were made, not misleading;

          (c)   The Shares, when paid for by the Buyers, shall be duly
authorized and validly issued and when issued and delivered, will be fully paid
and nonassessable;

          (d)   This Agreement has been duly authorized, validly executed and
delivered on behalf of the Company and is a valid and binding agreement and

this Agreement and the other agreements and documents contemplated hereby and to
perform its obligations hereunder and thereunder;

          (e)   The execution and delivery of this Agreement, the issuance of
the Shares and the consummation of the transactions contemplated by this
Agreement by the Company, will not conflict with or result in a breach of or a
default under any of the terms or provisions of, the Company's certificate of
incorporation or by-laws, or of any material provision of any indenture,
mortgage, deed of trust or other material agreement or instrument to which the
Company is a party or by which it or any of its material properties or assets is
bound, any material provision of any law, statute, rule, regulation, or any
existing applicable decree, judgment or order by any court, Federal or state
regulatory body, administrative agency, or other governmental body having
jurisdiction over the Company, or any of its material properties or assets or
will result in the creation or imposition of any material lien, charge or
encumbrance upon any material property or assets of the Company or any of its
subsidiaries pursuant to the terms of any agreement or instrument to which any
of them is a party or by which any of them may be bound or to which any of their
property or any of them is subject;

          (f)   Except as disclosed herein, and based upon the representations
and warranties of the Buyers set forth herein, no authorization, approval,
filing with or consent of any governmental body is required for the issuance and
sale of the Shares to the Buyers pursuant to this Agreement;

          (g)   There is no action, suit or proceeding before or by any court or
governmental agency or body, domestic or foreign, now pending against or
affecting the Company, or any of its properties, which would reasonably be
anticipated to result in a Material Adverse Effect, except as disclosed to the
Buyers or set forth in the Public Documents;

          (h)   Subsequent to the dates as of which information is given in the
Public Documents, except as contemplated herein, the Company has not incurred

and there has not been any change in its capitalization or any Material Adverse
Effect; and

          (i)   The Company has sufficient title and ownership of all
trademarks, service marks, trade names, copyrights, patents, trade secrets and
other proprietary rights necessary for

the Public Documents without any conflict with or infringement of the rights of
others. Except as set forth in the Public Documents, there are no material
outstanding options, licenses or agreements of any kind relating to the
foregoing, nor is the Company bound by or party to any material options,
licenses or agreements of any kind with respect to the trademarks, service

person, to which any such indemnified party may become subject under the
Securities Act, or under any other statute, at common law or otherwise, insofar

     WHEREAS, to induce the Investors to execute and deliver the Purchase
Agreement, the Company has agreed to provide certain registration rights under
the Securities Act of 1933, as amended, and the rules and regulations
thereunder, or any similar successor statute (collectively, the "Securities
Act"), with respect to the Shares;

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
contained herein and other good and valuable consideration, the receipt and

the Company; or (b) any material engagement or activity by the Company which
would, in the good faith determination of the Board of Directors of the Company,

          (iii) "Register," "Registered," and "Registration" refer to
registration effected by preparing and filing a Registration Statement or
Statements in compliance with the Securities Act and pursuant to Rule 415 under
the Securities Act or any successor rule providing for offering securities on a

          (v)   "Registration Statement" means a registration statement of the

     (b)  Capitalized terms used herein and not otherwise defined herein shall

     2.   REGISTRATION.

     (a)  MANDATORY REGISTRATION. The Company shall prepare and file with the
SEC on or before November 30, 1999 (the "Filing Date") a Registration Statement
on Form S-3 (or such other applicable form), registering for resale by the
Investors all of the Shares, or an amendment to any pending Company Registration
Statement on Form S-3 (or such other applicable form) and such Registration
Statement or amended Registration Statement shall state that, in accordance with
Rule 457 under the Securities Act, it also covers such indeterminate number of
additional shares of Common Stock as may become issuable to prevent dilution
resulting from stock splits, or stock dividends, and the Company shall use its
best efforts to cause the Registration Statement to be declared effective by
December 15, 1999 but in no event later than ninety (90) days after the Filing
Date. Notwithstanding the foregoing, if 500,000 freely tradable shares of Common
Stock have been delivered to the Investors prior to the filing of a Registration
Statement, then the Filing Date shall be within ten (10) days after the 1999
Annual Meeting of Stockholders of the Company, which is scheduled to occur on
December 21, 1999, but in no event later than December 31, 1999. If the Company
is notified orally or in writing by the SEC that the SEC has no comments with
respect to the Registration Statement (the "SEC Notice"), the Company shall use
its best efforts to cause the Registration Statement to be declared effective no
later than five (5) business days after receipt of the SEC Notice.

     (b)  Payments by the Company.

          (i)   If the Registration Statement covering the Registrable
Securities required to be filed by the Company pursuant to Section 2(a) hereof
has not been filed by the Filing Date (the "Required Filing Date") and/or has
not been declared effective by the earlier of (i) five (5) business days after
the Company receives the SEC Notice and (ii) ninety (90) days after the Filing
Date (the "Required Effective Date") (except as provided by the last sentence of
Section 2(a) with respect to the registration of additional shares of Common
Stock), then the Company will make payments to the Investors in such amounts and
at such times as shall be determined pursuant to this Section 2(b).

          (ii)  The amount to be paid by the Company to the Investors as



                                        2

<PAGE>   3

liquidated damages for such failure and not as a penalty shall be equal to one
percent (1%) of the purchase price paid by the Investors for all shares of
Common Stock purchased and then outstanding pursuant to the Purchase Agreement
for the initial thirty (30) day period until the Registration Statement has been
filed and/or declared effective, which shall be pro rated for such periods less
than thirty (30) days and two percent (2%) of the purchase price paid by the
Investors for each thirty (30) day period thereafter until the Registration
Statement has been filed and/or declared effective (which shall be also pro
rated, as aforesaid) (the "Periodic Amount"). The liquidated damages shall be
paid by the Company in cash upon demand.

          (iii) The parties acknowledge that the damages which may be incurred
by the Investors if the Registration Statement is not filed by the Required
Filing Date or if the Registration Statement has not been declared effective by
the Required Effective Date may be difficult to ascertain. The parties agree
that the Periodic Amount represents a reasonable estimate on the part of the
parties, as of the date of this Agreement, of the amount of such damages.

          (iv)  Notwithstanding the foregoing, the amounts payable by the
Company pursuant to this provision shall not be payable to the extent any delay
in the effectiveness of the Registration Statement occurs because of an act of,
or a failure to act or to act timely by the Investors or its counsel, or as a
result of force majeure, or in the event all of the Registrable Securities may
be sold pursuant to Rule 144 (without volume limitation) or another available
exemption under the Act. The payment of such liquidated damages shall not
relieve the Company from its obligations to register the Registrable Securities.
If the Company does not pay the liquidated damages in a timely fashion set forth
herein, it will pay to the Investors the reasonable costs of collection,
including attorneys fees, in addition to the liquidated damages.

     3.   OBLIGATIONS OF THE COMPANY. In connection with the registration of the
Registrable Securities, the Company shall do each of the following.

     (a)  Prepare promptly and file with the SEC not later than the Filing Date,

become effective the earlier of (i) five (5) business days after receipt of the
SEC Notice and (ii) ninety (90) days after the Filing Date and keep the
Registration Statement effective at all times until the earliest (the

necessary to make the statements therein, in light of the circumstances in which
they were made, not misleading;

     (b)  Prepare and file with the SEC such amendments (including
post-effective amendments) and supplements to the Registration Statement and the
prospectus used in connection with the Registration Statement as may be
necessary to keep the Registration

circumstances under which they were made, not misleading, or (z) the occurrence
or existence of any pending corporate development that, in the reasonable
discretion of the Company, makes it appropriate to suspend the availability of
the Registration Statement, and promptly to prepare and file a supplement or
amendment to the Registration Statement to correct such untrue statement or
omission, and deliver two (2) copies of such supplement or amendment to the
Investors or such additional copies as the Investors may reasonably request;
provided that, for not more than twenty (20) days (or a total of not more than
forty-five (45) days in any twelve (12) month period, the Company may delay the
disclosure of material non-public information concerning the Company (as well as
prospectus or Registration Statement updating) the disclosure of which at the
time is not, in the good faith opinion of the Company, the best interests of the
Company and in the opinion of counsel to the Company (an "Allowed Delay");
provided, further, that the Company shall promptly (i) notify the Investors in

     (a)  It shall be a condition precedent to the obligations of the Company to

                                        5

<PAGE>   6

Registrable Securities held by it, as shall be reasonably requested by the

may reasonably request. At least two (2) business days prior to the first
anticipated filing date of the Registration Statement, the Company shall notify
each Investor of the information the Company requires from such Investor (the

file the Registration Statement without including Registrable Securities of such
Non-Responsive Investor;

     (b)  Each Investor by such Investor's acceptance of the Registrable
Securities agrees to cooperate with the Company as reasonably requested by the
Company in connection with the preparation and filing of the Registration
Statement hereunder, unless such Investor has notified the Company in writing of

Securities from the Registration Statement; and

     (c)  Each Investor agrees that, upon receipt of any notice from the Company
of the happening of any event of the kind described in Section 3(e), 3(f) or

Registrable Securities pursuant to the Registration Statement covering such
Registrable Securities until such Investor's receipt of the copies of the
supplemented or amended prospectus contemplated by Section 3(e), 3(f) or 3(k)
and, if so directed by the Company, such Investor shall deliver to the Company
(at the expense of the Company) or destroy (and deliver to the Company a
certificate of destruction) all copies in such Investor's possession, of the
prospectus covering such Registrable Securities current at the time of receipt
of such notice.

     5.   EXPENSES OF REGISTRATION. All reasonable expenses, other than
underwriting discounts and commissions incurred in connection with
registrations, filings or qualifications pursuant to Section 3, but including,
without limitation, all registration, listing, and qualifications fees, printers
and accounting fees, the fees and disbursements of counsel for the Company,
shall be borne by the Company.

     6.   INDEMNIFICATION. In the event any Registrable Securities are included
in a Registration Statement under this Agreement:

     (a)  To the extent permitted by law, the Company will indemnify and hold
harmless each Investor who holds such Registrable Securities, the directors, if
any, of such Investor, the officers and agents, if any, of such Investor, each
person, if any, who controls any Investor within the meaning of the Securities
Act or the Exchange Act (each, an "Indemnified Person" or "Indemnified Party"),
against any losses, claims, damages, liabilities or expenses (joint or several)
incurred (collectively, "Claims") to which any of them may become subject under
the Securities Act, the Exchange Act or otherwise, insofar as such Claims (or
actions or proceedings, whether commenced or threatened, in respect thereof)
arise out of or are based upon any of the following statements, omissions or
violations in the Registration Statement, or any post-effective amendment
thereof, or any prospectus included therein: (i) any untrue statement or alleged
untrue statement of a material fact contained in the Registration Statement or
any



                                        6

<PAGE>   7

post-effective amendment thereof or the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, (ii) any untrue statement or alleged untrue
statement of a material fact contained in the final prospectus (as amended or
supplemented, if the Company files any amendment thereof or supplement thereto
with the SEC) or the omission or alleged omission to state therein any material
fact necessary to make the statements made therein, in light of the
circumstances under which the statements therein were made, not misleading or
(iii) any violation or alleged violation by the Company of the Securities Act,
the Exchange Act, any state securities law or any rule or regulation under the
Securities Act, the Exchange Act or any state securities law (the matters in the
foregoing clauses (i) through (iii) being, collectively, "Violations"). Subject
to clause (b) of this Section 6, the Company shall reimburse the Investors,
promptly as such expenses are incurred and are due and payable, for any legal
fees or other reasonable expenses incurred by them in connection with
investigating or defending any such Claim. Notwithstanding anything to the
contrary contained herein, the indemnification agreement contained in this
Section 6(a) shall not (I) apply to a Claim arising out of or based upon a
Violation which occurs in reliance upon and in conformity with information
furnished in writing to the Company by or on behalf of any Indemnified Person
expressly for use in connection with the preparation of the Registration
Statement or any such amendment thereof or supplement thereto, if such
prospectus was timely made available by the Company pursuant to Section 3(c)
hereof; (II) be available to the extent such Claim is based on a failure of the
Investors to deliver or cause to be delivered the prospectus made available by
the Company; or (III) apply to amounts paid in settlement of any Claim if such
settlement is effected without the prior written consent of the Company, which
consent shall not be unreasonably withheld. Each Investor will indemnify the
Company and its officers, directors and agents against any claims arising out of
or based upon a Violation which occurs in reliance upon and in conformity with
information furnished in writing to the Company, by or on behalf of such
Investor, expressly for use in connection with the preparation of the
Registration Statement, subject to such limitations and conditions as are
applicable to the Indemnification provided by the Company to this Section 6.
Such indemnity shall remain in full force and effect regardless of any
investigation made by or on behalf of the Indemnified Person and shall survive
the transfer of the Registrable Securities by the Investors pursuant to Section
9.

     (b)  Promptly after receipt by an Indemnified Person or Indemnified Party
under this Section 6 of notice of the commencement of any action (including any
governmental action), such Indemnified Person or Indemnified Party shall, if a
Claim in respect thereof is to be made against any indemnifying party under this
Section 6, deliver to the indemnifying party a written notice of the
commencement thereof and the indemnifying party shall have the right to
participate in, and, to the extent the indemnifying party so desires, jointly
with any other indemnifying party similarly noticed, to assume control of the
defense thereof with counsel mutually satisfactory to the indemnifying party and
the Indemnified Person or the Indemnified Party, as the case may be. In case any
such action is brought against any Indemnified Person or Indemnified Party, and
it notifies the indemnifying party of the commencement thereof, the indemnifying
party will be entitled to participate in, and, to the extent that it may wish,
jointly with any other indemnifying party similarly notified, assume the defense
thereof, subject to the provisions herein stated and after notice from the
indemnifying party to such Indemnified Person or Indemnified Party of its
election so to assume the defense thereof, the indemnifying party will not be
liable to such Indemnified Person or Indemnified Party under this Section 6 for
any legal



                                        7

<PAGE>   8

or other reasonable out-of-pocket expenses subsequently incurred by such
Indemnified Person or Indemnified Party in connection with the defense thereof
other than reasonable costs of investigation, unless the indemnifying party
shall not pursue the action of its final conclusion. The Indemnified Person or
Indemnified Party shall have the right to employ separate counsel in any such
action and to participate in the defense thereof, but the fees and reasonable
out-of-pocket expenses of such counsel shall not be at the expense of the
indemnifying party if the indemnifying party has assumed the defense of the
action with counsel reasonably satisfactory to the Indemnified Person or
Indemnified Party. The failure to deliver written notice to the indemnifying
party within a reasonable time of the commencement of any such action shall not
relieve such indemnifying party of any liability to the Indemnified Person or
Indemnified Party under this Section 6, except to the extent that the
indemnifying party is prejudiced in its ability to defend such action. The
indemnification required by this Section 6 shall be made by periodic payments of
the amount thereof during the course of the investigation or defense, as such
expense, loss, damage or liability is incurred and is due and payable.

     7.   CONTRIBUTION. To the extent any indemnification by an indemnifying
party is prohibited or limited by law, the indemnifying party agrees to make the
maximum contribution with respect to any amounts for which it would otherwise be
liable under Section 6 to the fullest extent permitted by law; provided,
however, that (a) no contribution shall be made under circumstances where the
maker would not have been liable for indemnification under the fault standards
set forth in Section 6; (b) no seller of Registrable Securities guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any seller of Registrable
Securities who was not guilty of such fraudulent misrepresentation; and (c)
contribution by any seller of Registrable Securities shall be limited in amount
to the net amount of proceeds received by such seller from the sale of such
Registrable Securities.

     8.   REPORTS UNDER EXCHANGE ACT. With a view to making available to the
Investors the benefits of Rule 144 promulgated under the Securities Act or any
other similar rule or regulation of the SEC that may at any time permit the
Investors to sell securities of the Company to the public without registration
("Rule 144"), the Company agrees to:

     (a)  make and keep public information available, as those terms are
understood and defined in Rule 144;

     (b)  file with the SEC in a timely manner all reports and other documents
required of the Company under the Securities Act and the Exchange Act; and

     (c)  furnish to each Investor so long as such Investor owns Registrable
Securities, promptly upon request, (i) a written statement by the Company that
it has complied with the reporting requirements of Rule 144, the Securities Act
and the Exchange Act, (ii) a copy of the most recent annual or quarterly report
of the Company and such other reports and documents so filed by the Company and
(iii) such other information as may be reasonably requested to permit the
Investors to sell such securities pursuant to Rule 144 without registration.

     9.   ASSIGNMENT OF THE REGISTRATION RIGHTS. The rights to have the Company
register Registrable Securities pursuant to this Agreement shall be
automatically assigned by the



                                        8

<PAGE>   9

Investors to any transferee of the Registrable Securities only if: (a) the
Investors agree in writing with the transferee or assignee to assign such
rights, and a copy of such agreement is furnished to the Company within a
reasonable time after such assignment, (b) the Company is, within a reasonable
time after such transfer or assignment, furnished with written notice of (i) the
name and address of such transferee or assignee and (ii) the securities with
respect to which such registration rights are being transferred or assigned, (c)
immediately following such transfer or assignment the further disposition of
such securities by the transferee or assignee is restricted under the Securities
Act and applicable state securities laws, and (d) at or before the time the
Company received the written notice contemplated by clause (b) of this sentence
the transferee or assignee agrees in writing with the Company to be bound by all
of the provisions contained herein. In the event of any delay in filing or
effectiveness of the Registration Statement as a result of such assignment, the
Company shall not be liable for any damages arising from such delay, or the
payments set forth in Section 2(b) hereof.

     10.  AMENDMENT OF REGISTRATION RIGHTS. Any provision of this Agreement may
be amended and the observance thereof may be waived (either generally or in a
particular instance and either retroactively or prospectively), only with the
written consent of the Company and the Investors. Any amendment or waiver
effected in accordance with this Section 10 shall be binding upon the Investor
and the Company.

     11.  MISCELLANEOUS. (a) A person or entity is deemed to be a holder of
Registrable Securities whenever such person or entity owns of record such
Registrable Securities. If the Company receives conflicting instructions,
notices or elections from two or more persons or entities with respect to the
same Registrable Securities, the Company shall act upon the basis of
instructions, notice or election received from the registered owner of such
Registrable Securities.

     (b)  Notices required or permitted to be given hereunder shall be in

                                ESCROW AGREEMENT

        ESCROW AGREEMENT (the "Escrow Agreement") made as of the 19th day of
November, 1999, by and among XYBERNAUT CORPORATION, a Delaware corporation with
offices at 12701 Fair Lakes Circle, Suite 550, Fairfax, Virginia 22033 (the
"Company"), BALMORE FUNDS, S.A., a corporation organized under the laws of the
British Virgin Islands, with offices at c/o Trident Trust Company (BVI) Limited,
Trident Chambers, Road Town, Tortola, British Virgin Islands and AUSTOST ANSTALT
SCHAAN, a corporation organized under the laws of Liechtenstein corporation,
with offices at Ladstrasse 163, 9494 Furstentums, Vaduz, Liechtenstein
(together, the "Purchasers"), and PARKER CHAPIN FLATTAU & KLIMPL, LLP, a New
York limited liability partnership with offices at 1211 Avenue of the Americas,
New York, New York 10027, as escrow agent (the "Escrow Agent").

                              W I T N E S S E T H:

     WHEREAS, the Company desires to raise capital for general working capital
purposes and acquisitions;

     WHEREAS, the Company and the Purchasers have agreed that, in order to raise
capital, the Company shall issue and sell to the Purchasers an aggregate of
1,000,000 shares of the Company's common stock, $0.01 par value per share (the
"Common Stock"), for an aggregate purchase price of $3,000,000.00 (the "Sale");

     WHEREAS, pursuant to the Sale, the Company will enter into a Purchase
Agreement dated as of November 19, 1999 (the "Purchase Agreement") with the
Purchasers; and

     WHEREAS, the Purchase Agreement contemplates that all funds shall be paid
into escrow and the original certificates representing the Common Stock (the
"Certificates") shall be held in escrow prior to the Closing Date (as defined in
the Purchase Agreement) and the Escrow Agent has agreed to receive, hold and pay
such funds and to receive such Certificates upon the terms and subject to the
conditions hereinafter set forth.

     NOW, THEREFORE, in consideration of the mutual covenants herein contained,
and for other good and valuable consideration, the receipt and sufficiency of
which is hereby acknowledged, the parties to this Escrow Agreement hereby agree
as follows:

          1.    Defined Terms. Capitalized terms used and not otherwise defined
herein shall have the meanings respectively assigned to them in the Purchase
Agreement.

          2.    Escrow of Funds. At or prior to the Closing Date, the following
shall occur: (a) the Purchasers shall remit by wire transfer the Purchase Price
to the Escrow Agent pursuant to this Escrow Agreement as payment in full for the
Common Stock (the "Escrow Amount"); (b) the Company shall deliver or cause to be
delivered to Escrow Agent the




<PAGE>   2

Certificates registered in the name of the Purchasers (or any nominee designated
by the Purchasers within three days before the Closing Date), free and clear of
all liens, claims, charges and encumbrances. The Escrow Agent shall hold the
Escrow Amount and the Certificates and shall deliver them or redeliver them to
the Company or to the Purchasers, as applicable, only in accordance with the
terms and conditions of this Escrow Agreement.

          3.    Investment of Funds. The Escrow Agent shall invest the monies in
the Escrow Amount in an interest bearing bank account with, or certificates of
deposit or time deposits with maturities of no more than thirty (30) days issued
by, a domestic commercial bank or such other bank or other financial institution
as it normally holds such funds.

          4.    Release of Funds. (a) The Escrow Agent shall release the Escrow
Amount and the Certificates upon receipt, at any time, of instructions from the
Company and the Purchasers directing the manner in which the return or other
distribution of the funds in the Escrow Amount and the Certificates are to be
made.

          (b)   Immediately following notification to the Escrow Agent by the
Company and the Purchasers that each of the conditions precedent to the Closing
has been satisfied or waived, the Company shall be paid the Escrow Amount and
the Purchasers shall receive the Certificates.

          (c)   If no Closing occurs and the Escrow Agent does not receive joint
instructions of the Company and the Purchasers regarding an extension of the
Closing Date, the Escrow Agent shall promptly thereafter return the Escrow
Amount to the Purchasers and the Certificates to the Company.

          (d)   Any interest earned on the Escrow Amount shall be paid to the
party receiving the Escrow Amount.

          5.    Further Assurances. The Company and the Purchasers agree to do
such further acts and to execute and deliver such statements, assignments,
agreements, instruments and other documents as the Escrow Agent from time to
time reasonably may request in connection with the administration, maintenance,
enforcement or adjudication of this Escrow Agreement in order (a) to give the
Escrow Agent confirmation and assurance of the Escrow Agent's rights, powers,
privileges, remedies and interests under this Escrow Agreement and applicable
law, (b) to better enable the Escrow Agent to exercise any such right, power,
privilege, remedy or interest, or (c) to otherwise effectuate the purpose and
the terms and provisions of this Escrow Agreement, each in such form and
substance as may be reasonably acceptable to the Escrow Agent.

          6.    Conflicting Demands. If conflicting or adverse claims or demands
are made or notices served upon the Escrow Agent with respect to the escrow
provided for herein, the Company and the Purchasers agree that the Escrow Agent
shall refuse to comply with any such claim or demand and withhold and stop all
further performance of this escrow so long as such disagreement shall continue.
In so doing, the Escrow Agent shall not be or become liable for damages, losses,
costs, expenses or interest to any or any other person for its failure to



                                       -2-

<PAGE>   3

comply with such conflicting or adverse demands. The Escrow Agent shall be
entitled to continue to so refrain and refuse to so act until such conflicting
claims or demands shall have been finally determined by a court or arbitrator of
competent jurisdiction or shall have been settled by agreement of the parties to
such controversy, in which case the Escrow Agent shall be notified thereof in a
notice signed by such parties. The Escrow Agent may also elect to commence an
interpleader or other action for declaratory judgment for the purpose of having
the respective rights of the claimants adjudicated, and may deposit with the
court all funds held hereunder pursuant to this Escrow Agreement; and if it so
commences and deposits, the Escrow Agent shall be relieved and discharged from
any further duties and obligations under this Escrow Agreement.

          7.    Disputes. Each of the parties hereto hereby covenants and agrees
that the Federal or state courts located in the Borough of Manhattan, State of
New York shall have jurisdiction over any dispute with the Escrow Agent or
relating to this Escrow Agreement.

          8.    Expenses of the Escrow Agent. The Company agrees to pay any and
all out-of-pocket costs and expenses incurred by the Escrow Agent in connection
with all waivers, releases, discharges, satisfactions, modifications and
amendments of this Escrow Agreement, the administration and holding of the
Escrow Amount and the investment of such funds, and the enforcement, protection
and adjudication of the parties' rights hereunder by the Escrow Agent,
including, without limitation, the out-of-pocket disbursements and expenses of
the Escrow Agent itself and those of other attorneys it may retain, if any. The
Company shall be liable to the Escrow Agent for any expenses payable by the
Escrow Agent.

          9.    Reliance on Documents and Experts. The Escrow Agent shall be
entitled to rely upon any notice, consent, certificate, affidavit, statement,
paper, document, writing or communication (which to the extent permitted
hereunder may be by telegram, cable, telex, telecopier, or telephone) reasonably
believed by it to be genuine and to have been signed, sent or made by the proper
person or persons, and upon opinions and advice of legal counsel (including
itself or counsel for any party hereto), independent public accountants and
other experts selected by the Escrow Agent and mutually acceptable to each of
the Company and the Purchasers. The Escrow Agent shall not be responsible to
review the Certificates other than to confirm that it has been signed or to
determine the clearance of checks received for the Escrow Amount.

          10.   Status of the Escrow Agent, Etc. The Escrow Agent is acting
under this Escrow Agreement as a stakeholder only. No term or provision of this
Escrow Agreement is intended to create, nor shall any such term or provision be
deemed to have created, any joint venture, partnership or attorney-client
relationship between or among the Escrow Agent and the Company or the
Purchasers. This Escrow Agreement shall not be deemed to prohibit or in any way
restrict the Escrow Agent's representation of the Company, who may be advised by
the Escrow Agent on any and all matters pertaining to this Escrow Agreement. To
the extent the Company has been represented by the Escrow Agent, the Company
hereby waives any conflict of interest and irrevocably authorizes and directs
the Escrow Agent to carry out the terms and provisions of this Escrow Agreement
fairly as to all parties, without regard to any such representation and
irrespective of the impact upon the Company. The Escrow Agent's only duties are
those expressly set forth in this Escrow Agreement, and each of the Company and
the



                                       -3-

<PAGE>   4

Purchasers authorize the Escrow Agent to perform those duties in accordance with
its usual practices in holding funds of its own or those of other escrows. The
Escrow Agent may exercise or otherwise enforce any of its rights, powers,
privileges, remedies and interests under this Escrow Agreement and applicable
law or perform any of its duties under this Escrow Agreement by or through its
partners, employees, attorneys, agents or designees.

          11.   Exculpation. The Escrow Agent and its designees, and their
respective partners, employees, attorneys and agents, shall not incur any
liability whatsoever for the investment or disposition of funds or the taking of
any other action in accordance with the terms and provisions of this Escrow
Agreement, for any mistake or error in judgment, for compliance with any
applicable law or any attachment, order or other directive of any court or other
authority (irrespective of any conflicting term or provision of this Escrow
Agreement), or for any act or omission of any other person selected with
reasonable care and engaged by the Escrow Agent in connection with this Escrow
Agreement (other than for such Escrow Agent's or such person's own acts or
omissions breaching a duty owed to the claimant under this Escrow Agreement and
amounting to gross negligence or willful misconduct as finally determined
pursuant to applicable law by a governmental authority having jurisdiction); and
each of the Company and the Purchasers hereby waives any and all claims and
actions whatsoever against the Escrow Agent and its designees, and their
respective partners, employees, attorneys and agents, arising out of or related
directly or indirectly to any and all of the foregoing acts, omissions and
circumstances. Furthermore, the Escrow Agent and its designees, and their
respective partners, employees, attorneys and agents, shall not incur any
liability (other than for a person's own acts or omissions breaching a duty owed
to the claimant under this Escrow Agreement and amounting to willful misconduct
as finally determined pursuant to applicable law by a governmental authority
having jurisdiction) for other acts and omissions arising out of or related
directly or indirectly to this Escrow Agreement or the Escrow Amount; and each
of the Company and the Purchasers hereby expressly waives any and all claims and
actions (other than those attributable to a person's own acts or omissions
breaching a duty owed to the claimant and amounting to gross negligence or
willful misconduct as finally determined pursuant to applicable law by a
governmental authority having jurisdiction) against the Escrow Agent and its
designees, and their respective partners, employees, attorneys and agents,
arising out of or related directly or indirectly to any and all of the foregoing
acts, omissions and circumstances.

          12.   Indemnification. The Escrow Agent and its designees, and their
respective partners, employees, attorneys and agents, shall be indemnified,
reimbursed, held harmless and, at the request of the Escrow Agent, defended, by
the Company from and against any and all claims, liabilities, losses and
expenses (including, without limitation, the reasonable disbursements, expenses
and fees of their respective attorneys) that may be imposed upon, incurred by,
or asserted against any of them, arising out of or related directly or
indirectly to this Escrow Agreement or the Escrow Amount, except such as are
occasioned by the indemnified person's own acts and omissions breaching a duty
owed to the claimant under this Escrow Agreement and amounting to willful
misconduct as finally determined pursuant to applicable law by a governmental
authority having jurisdiction.

          13.   Notices. Any notice required or permitted hereunder shall be
given in writing (unless otherwise specified herein) and shall be deemed

at its option, elect to resign its duties as Escrow Agent under this Escrow

covenants and other agreements made by or on behalf of each of the Company and
the Purchasers in this Escrow Agreement shall inure to the benefit of any
successor escrow agent hereunder; provided, however, that nothing herein shall

its rights or obligations hereunder to any other person (whether or not an
affiliate of the Company or the Purchasers) without the written consent of each
of the other parties nor to authorize or permit the Escrow Agent to assign any
of its duties or obligations hereunder except as provided in Section 17 hereof.

rights whatsoever as a shareholder of the Company, unless and to the extent
converted in accordance with the terms hereof.

       10.    The obligation of the Company for payment of principal, interest

Common Stock or any combination thereof, an annual bonus for the Company's
fiscal years of 2001 and 2002, in such an amount, if any, and based upon such
criteria as the Board of Directors of the Company Compensation Committee may
from time to time consider appropriate based upon the Executive's performance
during each such year (the "Discretionary Bonus"). The options granted pursuant
to this Section 4(b) shall be vested as of the date hereof, and shall be
subject to all of the terms and provisions of the Company's 1997 Stock Option
Plan, the Company's 1999 Stock Option Plan or any subsequently enacted stock
option plan, as applicable, except that they may be exercised in any amount at
any time after being vested until three (3) years from date of termination of
employment and shall be irrevocable during that period. Should there not be
sufficient options available or useable under said stock option Plans then,
unless otherwise agreed to by the Executive, the Company will nonetheless issue
said options to Executive, outside of said Plans, and register the shares of
Common Stock underlying the options within 180 days of their being issued.

         (d)      As additional consideration for Executive's services to the
Company hereunder, the Company shall pay Executive an annual bonus (the
"Performance Bonus"), based upon the Company's performance during the
Employment Term, commencing with the fiscal year from January 1, 2000 through
December 31, 2000, and for each fiscal year during the Employment Term
thereafter, if earned, in the form of options to purchase shares of the
Company's Common Stock, in an amount equal to one quarter of one percent
(0.25%) of the Revenue Goal (as hereinafter defined), if the Revenue Goal is
attained; or (ii) three-eighths of one percent (0.375%) of the increase, if
any, in the Market Cap from January 1 through December 31 of the applicable
fiscal year during the Employment Term. For purposes hereof, the term "Revenue
Goal" shall mean eighty-five percent (85%) of the Company's revenue goal for
each fiscal year during the Employment Term occurring after the Initial Period,
as set forth in its business plan for such year; provided that for the fiscal
year from January 1, 2000 through December 31, 2000 the Revenue Goal shall be
$20,000,000. For purposes hereof, the Market Cap Test shall be based on the
average of the number of shares outstanding and closing prices for the
Company's Common Stock for the thirty (30) days ended December 31 of the
applicable year compared to the same thirty (30) day period in the prior year.
The calculation of whether any Performance Bonus is due for any fiscal year
during the Employment Term occurring thereafter, as applicable, shall be made
by the Board of Directors promptly after the end of the fiscal year in respect
of the Market Cap test and upon the Company's issuance of its audited annual
financial statements in respect of the Revenue Goal test. The Performance
Bonus, if earned, shall be paid in the form of options to purchase shares of
the Company's Common Stock valued at an exercise price equal to the average of
the closing market price of the shares of the Company's Common Stock for the
thirty (30) days prior to the end of the applicable fiscal year. Any options
issued in respect of the Performance Bonus shall be subject to all of the terms
and provisions of the Company's 1999 Stock Option Plan or, if no shares are
available under such

                                       6

<PAGE>   7

Plan, or any subsequently enacted stock option plan, as applicable, except that
they may be exercised in any amount, at any time after being vested until three
(3) years from date of termination of employment and are irrevocable during
that period. Should there not be sufficient options available or useable under
said Stock Option Plan, the Company will use its best efforts to cause a new
Stock Option Plan to be adopted which cover the shares.

         (e)      Notwithstanding anything set forth in Section 4(c), in no
event shall the options granted to the Executive, if any, as the Performance
Bonus with respect to any fiscal year during the Employment Term exceed the
greater of (i) options exercisable into 100,000 shares of Common Stock or (ii)
one third of one percent (0.33%) of the Company's outstanding shares of capital
stock.

         (f)      Should there be a Change of Control of the Company or any
other transaction in which the Company is not the surviving entity during the
Employment Term, then as part of that transaction, the Company will require the
surviving entity to modify the Agreement in an equitable manner to provide the
Executive the same type of benefits that he is entitled to earn pursuant to
Section 4(c) of this Agreement.

         Section 5. Benefits, Vacation. (a) During the Employment Term, the
Executive shall be entitled to such insurance and health and medical benefits
as are generally made available to the senior executives of the Company, as a
group, pursuant to such plans as are from time to time maintained by the
Company; provided, however, that the Executive shall be required to comply with
the conditions of coverage attendant to such plans.

         (b)      During each contract year of the Employment Term, the
Executive shall be entitled to four (4) weeks of vacation. The Executive shall
take vacation at such time or times as the Executive desires, subject to the
concurrence of the Company based upon the then current business needs and
activities of the Company. Vacation shall accrue if unused during the term of
employment.

         (c)      During the Employment Term, the Executive shall be eligible
to participate in the profit sharing and other benefit plans that the Company
from time to time makes available to the senior executives of the Company as a
group, subject to the terms, provisions and conditions of such plans,
including, without limitation, any vesting periods and eligibility criteria.

         (d)      During the Employment Term, the Company shall pay to the
Executive a monthly car and non-accountable expense allowance of $2,250 per
month. In addition, the Company shall also pay reasonable legal and estate
planning expenses of Executive in an amount not to exceed $2,500 for each
calendar year during the Employment Term. The amounts paid and/or provided for
in this Section 5(d) shall be reported by the Company on Internal Revenue
Service Form 1099.

         (e)      The Company agrees to maintain in full force and effect the
life insurance policy in the face amount aggregating seven hundred and fifty
thousand dollars ($750,000.00), which are made payable to such beneficiary or
beneficiaries who are designated by the Executive. The Company shall pay all

Company shall assign such insurance policies to the Executive.

         Section 6. Business Expenses. The Executive shall be entitled to

         Section 7. Termination of Employment Term. (a) In the event of the
death of the Executive during the Employment Term, the Executive's employment
hereunder shall automatically terminate as of the date of death; provided,
however, that the Executive's estate or legal representative, as the case may
be, shall be entitled to receive, and the Company shall pay, any accrued and
unpaid Salary for a two (2) year period following the date of death, any
Performance Bonus that would be payable for the one (1) year period in which
the Executive died which are properly owing to the Executive pursuant to
Section 6 hereof.

         (b)      In the event of the Executive's Incapacity, the Company may,
in its sole discretion, terminate the Executive's employment hereunder upon
written notice to the Executive; provided, however, that the Executive or the
Executive's legal representative, as the case may be, shall be entitled to
receive, and the Company shall pay, (i) any accrued and unpaid Salary for a two
(2) year period from the date of termination, less any amounts received by the
Executive under any disability insurance policy maintained by the Company; and
(ii) any Performance Bonus that would be payable for the one (1) year period
after the Executive's employment is terminated due to Incapacity and

pursuant to Section 6 hereof, through the date of termination; provided that in
no event shall the amount of the Performance Bonus be less than fifty percent

         (c)      The Company shall have the right to terminate the Executive's
employment under this Agreement at any time for Cause upon written notice to
the Executive. In the event the Executive's employment hereunder is terminated

accrued and unreimbursed business expenses which are properly owing to the
Executive pursuant to Section 6 hereof through the date of termination.

         (d)      The Company shall have the right to terminate the Executive's

and (y) the remaining period of the Employment Term and (ii) pay any
unreimbursed business expenses which are properly owing to the Executive
pursuant to Section 6 hereof through the date of termination. In addition,

Company shall pay to the Executive the Performance Bonus, if any, for the
entire contract year in which the termination of the Executive's employment
with the Company hereunder occurs and for the contract year following the year
in which the termination occurred. The Executive shall not be under any
obligation to mitigate the Company's obligation pursuant to this Section 7(d)
by securing other employment or otherwise.

         (e)      The Executive shall have the right to terminate his
employment with the Company hereunder for Good Reason, upon not less than

Without Cause.

         (f)      The failure of the Company to continue the employment of the
Executive upon expiration of the entire three (3) year Employment Term shall
not be considered a termination of employment for purposes of this Agreement.
The Company's obligations with respect to the Performance Bonus for the last
year of the Employment Term, if any, shall survive the expiration of this
Agreement.

         Section 8. Inventions. Any Inventions originated or conceived by the
Executive related to the Company's business during his employment by the
Company or any Affiliate of the Company or with the use or assistance of the
facilities, materials or personnel of the Company or any Affiliate of the
Company, either solely or jointly with others, during the Employment Term shall

irrevocably assigns and transfers to the Company and agrees to transfer and
assign to the Company all of his right, title and interest in and to all
Inventions, and to applications for patents and patents granted upon such
Inventions and to all copyrightable material related thereto developed by the
Executive or under his supervision. The Executive agrees for himself and his
heirs and personal representatives, upon the request of the Company and at the
Company's expense, to do such acts, to execute such documents and instruments
and to participate in such legal proceedings as from time to time may be
necessary or required to apply for, secure, maintain, reissue, extend or defend
the worldwide rights of the Company in the Inventions. The Executive here
grants to the Company a power of attorney, which is irrevocable and coupled
with an interest, to execute any such documents and instruments if the
Executive is unable or fails to do so, after the request by the Company as
provided in the immediately preceding sentence. The Executive shall have no

Company, the Executive will

                                       9

<PAGE>   10

develop substantial expertise and knowledge with respect to all aspects of the
Company's business, affairs and operations and will have access to all
significant aspects of the business and operations of the Company and to
Confidential and Proprietary Information. The Executive acknowledges and agrees
that the Company will be damaged if the Executive were to breach any of the
provisions of this Section 9 or if the Executive were to disclose or make
unauthorized use of any Confidential and Proprietary Information. Accordingly,
the Executive expressly acknowledges and agrees that the Executive is
voluntarily entering into this Agreement and that the terms, provisions and
conditions of this Section 9 are fair and reasonable and necessary to
adequately protect the Company.

         (a)      The Executive hereby covenants and agrees that, during the
Employment Term and thereafter, unless otherwise authorized by the Company in
writing, the Executive shall not, directly or indirectly, under any
circumstance: (i) disclose to any other Person (other than in the regular
course of business of the Company) any Confidential and Proprietary
Information, other than pursuant to applicable law, regulation or subpoena or
with the prior written consent of the Company; (ii) act or fail to act so as to
impair the confidential or proprietary nature of any Confidential and
Proprietary Information; (iii) use any Confidential and Proprietary Information
related to the Company's business other than for the sole and exclusive benefit
of the Company; or (iv) offer or agree to, or cause or assist in the inception
or continuation of, any such disclosure, impairment or use of any Confidential
and Proprietary Information. Following the Employment Term, the Executive shall
return all documents, records and other items containing any Confidential and
Proprietary Information to the Company (regardless of the medium in which
maintained or stored), without retaining any copies, notes or excerpts thereof,
or at the request of the Company, shall destroy such documents, records and
items (any such destruction to be certified by the Executive to the Company in
writing).

         (b)      The Executive covenants and agrees that, while the Executive
is employed by the Company and for one (1) year after the Executive ceases to
be employed by the Company, if the Executive (i) voluntarily terminates his
employment with the Company for Good Reason or (ii) is terminated by the
Company for Cause, the Executive shall not, directly or indirectly, manage,
operate or control, or participate in the ownership, management, operation or
control of, or otherwise become interested in (whether as an owner,
stockholder, partner, lender, consultant, Executive, agent, supplier,
distributor or otherwise) any Competing Business or, directly or indirectly,
induce or influence any customer or other Person that has a business
relationship with the Company, or any Affiliate of the Company, to discontinue
or reduce the extent of such relationship; provided that in the case of a
termination by the Executive pursuant to clause (i) the Company at all times
continues to pay the amounts owing to the Executive pursuant to Section 7(b)
hereof. For purposes of this Agreement, the Executive shall be deemed to be
directly or indirectly interested in a business if he is engaged or interested
in that business as a stockholder, director, officer, Executive, agent,
partner, individual proprietor, consultant, advisor or otherwise, but not if
the Executive's interest is limited solely to the ownership of not more than 5%
of the securities of any class of equity securities of a corporation or other
Person whose shares are listed or admitted to trade on a national securities
exchange or are quoted on NASDAQ or a similar means if NASDAQ is no longer
providing such information.

         (c)      While the Executive is employed by the Company and for one
(1) year after the Executive ceases to be an employed by the Company, the
Executive shall not, directly or indirectly, solicit to employ for himself or
others any employee of the Company or any Affiliate of the Company who was an
employee of the Company or any Affiliate of the Company as of the date of the
termination of the Executive's employment with the Company, or to solicit any
such employee to leave such employee's employment or join the employ of
another, then or at a later time; provided that the foregoing shall not apply
to any family member of the Executive who is employed by the Company or any
such Affiliate or the Executive's administrative assistant.

         (d)      The parties agree that nothing in this Agreement shall be
construed to limit or negate the common law of torts, confidentiality, trade
secrets, fiduciary duty and obligations where such laws provide the Company
with any broader, further or other remedy or protection than those provided
herein.

         (e)      Because the breach of any of the provisions of this Section 9
may result in immediate and irreparable injury to the Company for which the
Company may not have an adequate remedy at law, the Company shall be entitled,
in addition to all other rights and remedies, to a decree of specific
performance of the restrictive covenants contained in this Section 9 and to a
temporary and permanent injunction enjoining such breach, without posting a
bond or furnishing similar security.

         Section 10. Severability. Each term and provision of this Agreement is
severable; the invalidity, illegality or unenforceability or modification of
any term or provision of this Agreement shall not affect the validity, legality
and enforceability of the other terms and provisions of this Agreement, which
shall remain in full force and effect. Since it is the desire and intent of the
parties that the provisions of this Agreement be enforced to the fullest extent
permissible under the laws and public policies applied in each jurisdiction in
which enforcement is sought, should any particular provision of this Agreement
be deemed invalid, illegal or unenforceable, the same shall be deemed reformed
and amended to delete that portion that is adjudicated to be invalid, illegal
or unenforceable and the deletion shall apply only with respect to the
operation of such provision and to the extent of such provision and, to the
extent that a provision of this Agreement would be deemed unenforceable by
virtue of its scope, but may be made enforceable by limitation thereon, each
party agrees that this Agreement shall be reformed and amended so that the same
shall be enforceable to the fullest extent permissible under the laws and
public policies applied in the jurisdiction in which enforcement is sought.

of the parties hereto shall bind and inure to the benefit of each of the
parties hereto, the heirs, executors, administrators and legal representatives
of the Executive and the successors and permitted assigns of the Company.
Neither this Agreement nor any rights or benefits hereunder may be assigned by

obligations hereunder to any other Person which purchases all or substantially
all of the common stock or assets of the
