ITEM 1. BUSINESS.

           This discussion contains forward-looking statements that involve
risks and uncertainties. Please review the information in light of the risk
factors and other cautionary statements identifying important factors that could
cause actual results to differ materially from those in the forward-looking
statements. In particular, please see "Risk Factors."

OVERVIEW

           Our company is a Multimedia Service Provider ("MSP") that intends to
deliver broadband interactive services at speeds of up to 45 Mbps through our
SatExpress satellite and terrestrial based network. We plan to offer broadcast,
multicast and high-speed Internet access services to, among others, high-end
consumers and corporate users that wish to extend their Internet and Intranet
connectivity to remote locations through Virtual Private Networks ("VPNs").

           We were incorporated on April 8, 1996 under the laws of the State of
North Carolina. During 1996 we were not yet operational and conducted no
business activity. Our operations commenced January 7, 1997, when we acquired
the assets and technology of Temasek Telephone, Inc. We initially focused on
developing multiplexers and high-speed Digital Subscriber Line ("DSL") devices
for Internet use.

           In May 1998, we made strategic changes in our business and focused on
acquiring additional technologies to bolster our satellite communication
development expertise. In September 1998, we acquired the assets of SatCom Media
Corporation after it had filed for bankruptcy, and have since developed our
SatExpress high-speed services.

           We plan to introduce our high-speed services to selected vertical
markets in the U.S. in the fourth quarter of 1999. We also intend to pursue
international markets to implement our services. Within the next 18 months, we
plan to deploy multiple Network Operating Centers ("NOCs") which will access
multiple satellites to provide a high-speed global network and implement
e-commerce, Intranet and bandwidth on demand applications for small business,
corporate and institutional users.

STRATEGY

           As the Internet takes on increased importance as an information
source and e-commerce vehicle, we anticipate large growth in the demand for
high-speed, cost-effective Internet access and broadband services. Today,
business customers must choose between low-speed analog connections, complex
Integrated Services Digital Network ("ISDN") dial access, cost-prohibitive T1
leased-line services or distance limited DSL services for their data services.
The greatest challenge for service providers offering these high-speed data
access solutions for business customers has been the inconsistent service of
local exchange carriers as the third-party connectivity for the last mile
solution. Our SatExpress network avoids the local access bottleneck and is
intended to provide the lucrative "middle-market" a solution for their
high-speed communication needs.

           We plan to expand solutions for broadband applications by leveraging
technologies for Internet Protocol ("IP") encapsulation and encryption,
conditional access, hybrid spread spectrum, error-correction, modulation and
radio frequency ("RF") techniques. Through these enabling technologies we plan
to deliver content and provide low cost, high-speed Internet access, broadcast
and multicast services via satellite for selected consumer, commercial and
vertical market applications.

           Our objective is to establish NOCs to deliver our services by
co-locating our equipment with major carriers, Competitive Local Exchange
Carriers ("CLECs") or teleports that have backbone fiber networks and


<PAGE>   3

local loop access. Strategic alliances and joint ventures with leading
manufacturers, communications companies, enterprise organizations, content
providers and internet service providers ("ISPs") are intended to maximize
market penetration and optimize network technologies for interactive broadband
applications. VPNs will be established on a shared Hub basis to take advantage
of economies of scale and provide services for the small and medium sized
business that cannot afford or do not have the expertise to operate their own
networks.

PRODUCT SERVICES

SATEXPRESS NETWORK

           Our SatExpress network is designed to deliver up to 45 Mbps of motion
picture quality video with embedded IP video/voice/data traffic to the desktop
PC or television. The system uses the internationally accepted DVB/MPEG-2 and
Internet TCP/IP standards to interface with legacy systems. The return
(upstream) path can be either terrestrial or a 64-384 Kbps satellite link that
lets the user bypass terrestrial networks and transport voice, video, and data
content entirely over the satellite.

SATEXPRESS HUB

           The Hub is the central controller of the SatExpress network. The Hub
communicates with the satellite, manages the network, performs accounting and
billing services tailored to customer requirements, originates content, and
provides end-users access to public networks and the World Wide Web. Hub
equipment will be co-located with carriers and teleports to establish NOCs.
Video servers, cache, multicast and other application servers will be installed
in the NOC, which shall be scaleable for linear growth.

           A NOC can provide traffic reports and throughput statistics for each
customer in support of service-level agreements. If a subscriber regularly hits
peak utilization rates, the NOC can then migrate the user upon request to a
higher speed service, at a correspondingly higher billing rate.

           The SatExpress Hub consists of the following equipment:

           -    The satellite uplink and downlink equipment including an antenna
                and RF radio;

           -    The gateway equipment including the video processing equipment,
                IP encoders, IP gateway, modulators, demodulators, MPEG
                encoders, a network management system, a billing and encryption
                system; and

           -    The servers and service delivery and monitoring equipment.

           We currently have a Hub which is located at our corporate facility
and is used for development and customer evaluation purposes. Our first
commercial Hub will be co-located at Level 3, in Sunnyvale California. Level 3
operates a national, dual OC-3 Internet backbone in the U.S. that rides on a
fiber-optic SONET infrastructure. Installation of the Level 3 Hub began in
September 1999 and we began providing initial commercial services there in
October 1999.

SPACE SEGMENT

           We intend to provide our satellite services through existing Ku band
satellites. We have entered into an agreement with Satelites Mexicanos S.A. de
C.V. ("Satmex") to acquire two 36 MHz Ku band transponders on the Satmex 5
satellite over the next five years. This relationship is intended to provide the
initial capacity to cover contemplated services to be offered in the U.S. and
South America. We also intend to



                                      -2-
<PAGE>   4

take advantage of the Loral Global Alliance worldwide network of satellite
services, of which Satmex is a member. The Loral Global Alliance provides a
network of regional and global operators including Satmex, EuropeStar and Loral
Skynet. Additional capacity can be acquired from satellite owner/operators as
services are required.

CUSTOMER PREMISE EQUIPMENT

           Each location subscribing to our services will require configurations
of the following equipment:

           1.   Outdoor Unit ("ODU"):

                -    Antenna and a low noise block amplifier; and

                -    Radio.

           2.   Indoor Unit ("IDU"):

                -    Set-top Box for applications such as the consumer market
                     for content multicast and high-speed Internet access; and

                -    Enterprise Unit (for applications such as the corporate
                     market for VPN Intranet applications).

           In each case the basic broadcast, multicast and Internet access
services will be available.

           We will utilize the off-the-shelf 2-way satellite return channel and
are developing a low cost, more intelligent, commercial quality Ku band
terminal. As currently envisioned, our terminal will consist of a low cost,
compact, 2-watt Ku-band transmitter/receiver and GPS receiver mounted to a 0.6
or 1.2 meter dish, the digital electronics for both the forward and return
communications links, TCP/IP interfaces to end-user equipment, and a processor
for data transport and networking protocols.

CUSTOMER EQUIPMENT SUPPLY

           We intend to purchase off the shelf customer equipment for the ODU
and IDU units. Several suppliers have been selected for initial delivery
configurations. Discussions are ongoing for custom requirements with selected
vendors to meet our future needs.

CUSTOMER EQUIPMENT INSTALLATION

           Third party installation companies will be used to install the
customer equipment. Our own service and support engineers will install initial
customer demonstration units and will train the third party installers.

CONTENT

           Content will be aggregated at our Hub, and delivered as multicast or
broadcast services direct to the customer or stored on our video servers for
scheduled or on demand delivery. Strategic alliance partners and other content
providers shall be responsible for obtaining the rights to additional content.



                                      -3-

THIRD PARTY APPLICATIONS

           Application software packages such as movies on demand ("MOD") are
being developed by strategic partners for selected vertical markets. Other
software packages for applications such as distance learning and video
conferencing may also be developed.

REGULATIONS

           We have FCC transmission license approval for the Hub currently
located at our facility and the Level 3 co-location facility planned to be
operational in October 1999. It is the responsibility of one of our
subcontractors to obtain any necessary approvals both in the U.S. and
internationally as new Hubs are deployed and new satellites are included in the
network for delivering services.

INTELLECTUAL PROPERTY

           We have attempted to select the "best of breed" technology available
from outside vendors and to integrate their products into our current network,
which has a terrestrial line from the customer to our Hub, and satellite from
the Hub to the customer.

           To reduce costs, improve efficiency, increase performance and serve
areas that do not have high-speed terrestrial services we are currently
developing a proprietary system. We intend to implement direct sequence spread
spectrum waveforms specifically developed for wideband applications. As
currently envisioned, the system will use a special form of synchronous
Frequency Division Multiple Access ("FDMA") and Code Division Multiple Access
("CDMA") integrated with Global Positioning System ("GPS") timing for maximum
satellite bandwidth utilization. The RF requirement will be implemented through
a low cost 2-watt Ku band radio.

           The external specifications and feasibility simulation studies have
been completed for the development system. The CDMA modems and controllers,
including the application specific integrated circuit ("ASIC") chip design will
be implemented through a contract with a third party end-to-end design house. A
third party company will develop the Ku band radio to our specifications. Two
patent applications have been prepared and we intend to submit these
applications to the U.S. Patent and Trademark Office.

HIGH-SPEED SERVICES

           Today's home users and small to medium-sized businesses desire the
same speed and services that large companies enjoy. But these users require a
cost-effective solution that is easy to install and which operates
transparently, without any intervention or ongoing technical support
requirements.

           For users without access to cable modems or analog DSL, and who also
want the capability to receive high quality video, a satellite connection is an
attractive option. We have created the SatExpress network to provide direct
video broadcast ("DVB") compliant television quality video broadcast and
multicast services, Internet TCP/IP voice, data and video streaming media and
web content. The network shall be integrated with existing wireline networks to
provide high-performance, interactive high-speed services, and provide DVB video
to the desktop or television simultaneously with TCP/IP data on the PC.

           Dial-up access solutions are too slow to support the latest broadband
applications. ISDN's dial-up 128 kbps is often cumbersome and inadequate,
high-speed leased-line alternatives are cost-prohibitive for most small and
medium-sized businesses, and DSL service has a distance limitation. SatExpress
gives the user the benefits of a leased line, including instant network access,
at a substantially lower cost.



                                      -4-
<PAGE>   6

           As enabled by our leading edge technology, the SatExpress network is
designed to support virtually all computers and workstations through the use of
TCP/IP interfaces to PCs and Ethernet LANs. Internet data is broadcast directly
to a standard satellite television dish and receiver at speeds of up to 45 Mbps,
bypassing the local exchange carrier.

           We provide an end-to-end IP solution for the broadband requirements
of our customers. Through programs with providers such as Level 3, we can
include terrestrial lines as part of our global network solution. Contracts and
the necessary equipment are in place to deliver the following services beginning
in October 1999 through the SatExpress network:

           -    High-speed Internet access;

           -    Multicast IP data and video; and

           -    Video Broadcast.

           We intend to offer additional services including VPN, Intranet, and
value added applications such as movies on demand, distance learning and video
conferencing beginning in the fourth quarter of 1999.

VIRTUAL PRIVATE NETWORKS ("VPNs")

           Low cost high-speed services have become a competitive requirement
for today's "push" and "pull" business applications, including Intranets,
Extranets, Virtual Private Networks ("VPNs"), email, electronic commerce, Web
hosting, video conferencing, collaborative computing, multimedia and more. The
corporate TCP/IP Intranet has become the information highway along which
business is conducted.

           The Extranet serves as an extension of the Intranet to external
business partners. In order to expedite information flow and order processing, a
limited trust is defined and established between the networked computer
resources of two or more companies. This arrangement is a secured hybrid link
between the relatively unsecured Internet and the secured Intranet. The Wide
Area Networking ("WAN") internetworking is a fixed or virtual link, depending
upon traffic volume. With the improvement in IP security, including firewalls
and VPN tools, Extranets are emerging as the preferred interconnectivity vehicle
between business partners.

           Our Intranet/Extranet market solutions will target business and
government users. We envision that our solutions will support the ongoing
transformation of communication networks within large and medium sized
businesses, including employee training and communication, division to
headquarters ordering and logistics tracking, customer support, marketing and ad
distribution, and international cross-border communication. The standardization
brought by electronic distribution for business-to-business communication has
found its way into internal company use to communicate between various corporate
platforms.

           Some illustrative uses of our corporate Intranet/Extranet services
are product announcements, promotional announcements with visual displays and ad
layouts, product placement and shelving diagrams. Our services are intended to
include delivery information and tracking, just-in-time inventory response to
logistics and problems, and collaborative forecasting and control of imports and
exports. These service areas facilitate reduction of delivery lead times and
inventory that result in substantial cost savings to our business and government
end users.

DISTANCE LEARNING

           For distance learning applications, SatExpress will enable an
instructor located at his home site, equipped with the latest teaching aids, to
broadcast a live teaching session to students located in remote classrooms or
offices thousands of miles away. In the classrooms or at their desktop, students
will be able to watch the teacher on a television screen or computer monitor and
ask or respond via video conferencing, IP text window, or IP Voice call
interaction. The teacher can remotely control the video camera in the classroom
to zoom in or pan the classroom. The teacher can take the classroom to an
Internet Website, representing the subject discussed, by hyperlinking to the
site, thus facilitating further instructional interactivity. The students can
also take web-based tests with real-time interaction with the remote teacher.
Enhanced features such as file transfer of instructional notes that have been
converted into electronic form via voice recognition software, as well as help
desks, fax, and remote printing are a few of the service features delivered by
SatExpress. The distance learning capability provided through SatExpress can
enhance learning productivity and help reduce training costs.

MARKETS AND CUSTOMERS

           We intend to offer the following high-speed services beginning in
October 1999:

           -    Multiple business and dwelling units; and

           -    Manufacturing companies.

           We intend to develop our customers through vertical market channels
such as integrators, consulting companies, marketing companies, trade
associations, broadband data service providers, content providers, CLECs that
wish to enhance their data service offerings and ISPs that are developing
application packages and targeting special markets and corporate users. We
intend to pursue other vertical markets, including the small and medium size
corporate Intranet market beginning in the fourth quarter of 1999.

REVENUE RECOGNITION POLICIES

           We anticipate that revenues will be generated from the following
sources:

           -    Providing internet access on a monthly fee basis;

           -    Delivering data and video content;

           -    Providing maintenance and support services; and

           -    Selling and installing equipment for use on customers' premises.

           We anticipate that revenues will be recognized as follows:

           -    Internet access revenue as billed on a monthly basis;

           -    Data and video content based on usage;

           -    Maintenance and support contracts over the applicable
                contractual period; and

           -    Customer premise equipment upon installation.

COMPETITION

           Our competition comes from both satellite and terrestrial network
solution providers. Currently, major fiber and cable suppliers and carriers are
striving to complete next generation terrestrial data network infrastructures at
a cost of several trillion US dollars. A very small percentage of the existing
local exchange carrier copper wire can support the Asychronous Digital
Subscriber Line ("ADSL") rates that are provided by the modems themselves. The
key to rapid deployment of new services is to provide a "last mile" bypass of
this wiring infrastructure. The SatExpress product line bypasses the local
exchange carrier via satellite.

           We do not compete directly with terrestrial service suppliers, but
instead, compliment them by delivering services that they cannot provide due to
"last mile" or critical technology limitations. SatExpress is particularly
attractive to distributed enterprises or at sites in sparsely populated areas
with limited terrestrial telecommunication infrastructure because satellite
network connections can be established in a fraction of the time and generally
at a fraction of the cost of terrestrial networks.

RESEARCH AND DEVELOPMENT

           Our product service development and engineering efforts focus on the
design and development of new technologies and product services to increase the
speed and efficiency of satellite communications and our ability to be an MSP.
Our research and development expenses for the period from April 1996 (inception)
to December 31, 1996, the years ended December 31, 1997 and 1998 and the six
months ended June 30, 1999 were $0, $306,637, $507,082 and $1,756,038.

EMPLOYEES

           As of June 30, 1999, we employed 17 employees and two independent
contractors located in our Sunnyvale, California headquarters. Our employees are
not covered by any collective bargaining agreements. We believe that its current
employee relations are satisfactory. There is significant competition in the San
Francisco Bay Area for employees with the managerial, technical, marketing,
sales and other skills required to operate our business. Our future success will
depend in significant part upon its ability to attract, retain and motivate
employees.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

           This Registration Statement contains forward-looking statements, the
accuracy of which involves risks and uncertainties. We use words such as
"anticipates," "believes," "plans," "expects," "future," "intends," and similar
expressions to identify forward-looking statements. The discussion and analysis
of financial condition and results of operations is based upon and should be
read in conjunction with the financial statements of the Company and the notes
thereto included elsewhere in this Registration Statement, as well as the
information contained under the headings, "Business" and "Risk Factors."

OVERVIEW

           Our company is a Multimedia Service Provider ("MSP") that intends to
deliver broadband interactive services at speeds of up to 45 Mbps through our
SatExpress satellite and terrestrial based network. We plan to offer broadcast,
multicast and high-speed Internet access services to high-end consumers and
corporate users that wish to extend their Internet and Intranet connectivity to
remote locations through Virtual Private Networks ("VPNs"). The market for the
Company's product services is rapidly evolving and is characterized by an
increasing number of new technologies, which include both satellite and
terrestrial network solution providers. The Company and its prospects must be
considered in light of the risks, expenses and difficulties encountered by
companies in the new and rapidly evolving market for our product services. See
"Risk Factors," generally.

           We have experienced net losses from operations of $12,566,127 or
$0.57 per share (basic and diluted), since inception in April, 1996 through June
30, 1999. We anticipate that we will continue to incur net losses into the
fourth quarter of 1999. These losses have developed mainly from our activities
to develop our product services and establish brand recognition through the
development of a viable sales channel.

           We intend our revenue to be generated from the sale of high speed
Internet access, the delivery of content and the provision of installation
maintenance and support services. We intend to market to various channels,
including multiple business and dwelling units and manufacturing companies. Our
policy is to recognize revenue as earned on either monthly or yearly bases or as
usage charges are incurred. We expect to provide allowance for returns and price
adjustments at the point of revenue recognition.

           We originally began operations by developing multiplexers and
high-speed DSL devices for Internet use. In May 1998, we made the strategic
decision to abandon the sales and marketing efforts behind our MUX-6 Multiplexer
and DigiCop internet connector products to pursue other lines of business. We
have written down all of the finished inventory and the parts and raw materials
related to these product services to their estimated net realizable value.

           We continue to expend substantial resources on sales and marketing in
our attempts to establish our product services as a viable alternative in the
MSP market. There can be no assurances, however, that we will achieve or sustain
profitability or positive cash flow from our operations. See "Risk Factors--We
Have a Limited Operating History," "--We May Have Insufficient Capital For
Future Operations", and "--We Face Obstacles Relating To Market Acceptance and
Distribution".

           Sales and marketing expenses consist primarily of compensation, costs
of promotional material, travel and advertising. Since inception in April 1996
through June 30, 1999, sales and marketing expenses have been $5,436,324. During
1997 and 1998, we expended considerable resources in Asia in an attempt to
establish a distribution channel and secure contracts with vendors for the MUX-6
and DigiCop product, which included governments and private companies. Our sales
and marketing expenses will grow rapidly as we



                                      -9-
<PAGE>   12

expand the sales and marketing efforts nationwide and internationally. We expect
to hire additional sales personnel in the fourth quarter of 1999.

           General and administrative expenses consist primarily of costs
associated with the internal costs of pursuing capital investment in the
Company, accounting and human resources needs, professional expenses, leasing of
facilities, insurance, legal, depreciation expenses, and compensation. Since
inception in April 1996 through June 30, 1999, general and administrative
expenses amounted to $3,418,469.

           As of December 31, 1998, we had operating loss carry forwards of
approximately $5,845,000 for federal purposes and $2,922,000 for state purposes.
The federal and state net operating loss carry forwards expire on various dates
through 2018. We have provided full valuation allowance against our deferred tax
assets, consisting primarily of net operating loss carry forwards, because of
the uncertainty regarding their realization. Further, such net operating loss
carry forwards could be subject to limitations due to changes in our ownership
resulting from equity financings.

RESULTS OF OPERATIONS

SIX MONTHS ENDED JUNE 30, 1999 AND 1998

           Revenue. We have not recognized any revenues for the years ended
December 31, 1997 and 1998 and the six months ended June 30, 1999.

           Research and development expenses. Research and development expenses
were $1,756,038 for the six months ended June 30, 1999, an increase from $30,888
for the six months ended June 30, 1998. Research and development expenses for
June 30, 1998 related to DigiCop and June 30, 1999 related primarily to the
effort to complete the development and testing of the DVB/IP network, including
compensation costs of approximately $1,300,000 related to the issuance of
warrants.

           Sales and marketing expenses. Sales and marketing expenses were
$3,134,146 for the six months ended June 30, 1999, an increase from $213,949 for
the six months ended June 30, 1998. This increase resulted primarily from the
hiring of additional sales and marketing personnel and the sales and marketing
to develop the business, including compensation costs of approximately
$1,300,000 related to the issuance of warrants.

           General and administrative expenses. General and administrative
expenses were $1,710,247 for the six months ended June 30, 1999, an increase
from $344,884 for the six months ended June 30, 1998. This increase resulted
from costs associated with raising additional capital, costs related to
operating in a larger overall facility and costs of hiring additional personnel,
including compensation costs of approximately $1,300,000 related to the issuance
of warrants.

YEARS ENDED DECEMBER 31, 1998 AND 1997

           Revenue. We have not recognized any revenues for the years ended
December 31, 1997 and 1998.

           Research and development expenses. Research and development costs in
1998 were $507,082, an increase from $306,637 in 1997. This increase was
primarily due to the purchase, in the fourth quarter of 1998, of certain
technologies in the form of in-process research and development, from SatCom
Media Corporation. Related expenses of $406,000 were charged to research and
development because the technology acquired and related products were in the
early stages of development and had not yet achieved technological feasibility.
The change from 1997 to 1998, net of the $406,000 charge, decreased due to the
fact



                                      -10-
<PAGE>   13

that in 1997 the DigiCop product incurred extensive development costs while the
significant costs related to the DVB/IP network did not begin until the first
quarter of 1999.

           Sales and marketing expenses. Sale and marketing expenses were
$586,529 in 1998, a decrease from $1,715,649 in 1997. This decrease was
primarily due to the significant costs incurred in 1997 in an attempt to secure
contracts and commitments in Asia. The costs included consulting fees related to
establishing a contract with the Republic of China for our multiplexer product.
Sales and marketing expenses for 1998 related primarily to the attempt to sell
our multiplexer product and Digicop products through the third quarter.

           General and administrative expenses. General and administrative
expenses were $1,188,071 in 1998, an increase from $520,151 in 1997. This
increase was primarily due to increases in the number of administrative
personnel, professional services fees and facility expenses to support the
growth of our operations.

           In January 1997 we acquired certain assets and rights to the MUX-6
multiplexer product from Temasek Telephone, Inc. Temasek Telephone, Inc. was
deemed to be a predecessor corporation, and accordingly, their statement of
operations and cash flow for the year ended December 31, 1996 are included
herein. There was little activity by the predecessor corporation in 1996, due to
lack of capital. The expenses primarily related to personnel, business
development and facilities costs.

LIQUIDITY AND CAPITAL RESOURCES

           Our principal sources of liquidity as of June 30, 1999 consisted of
$19,383,419 in cash and cash equivalents.

           Since inception in April 1996, we have financed ourselves primarily
through private equity financing. During the years ended December 31, 1997 and
1998, we received proceeds from the sale of stock of approximately $4,536,000.
During the six months ended June 30, 1999, we received net proceeds of
approximately $24,100,000 from the sale of common and preferred stock.

           Cash utilized by operating activities was $1,408,697 in the six
months ended June 30, 1999, $2,357,027 in the year ended December 31, 1998 and
$1,205,354 in the year ended December 31, 1997. The cash utilized in each of
these periods was due to net losses, as well as working capital required to fund
our growth in operations.

           Cash used in investing activities consisted primarily of capital
expenditures and advances to shareholders of $4,098,645 in the six months ended
June 30, 1999, $872,025 in the year ended December 31, 1998 and $138,359 in the
year ended December 31, 1997.

           Cash provided by financing activities was $24,885,100 for the six
months ended June 30, 1999, and $1,344,740 and $3,233,686 for the years ended
December 31, 1997 and 1998, respectively. Cash provided by financing activities
has been provided primarily from the sale of common and preferred stock.

           We believe our existing cash balances will be sufficient to meet our
cash requirements at least through the next twelve months. However, we may be
required, or could elect, to seek additional funding prior to that time. Our
future capital requirements will depend on many factors, including the rate of
revenue growth, the timing and extent of spending to support development efforts
and expansion of sales and marketing, the timing of introductions of new product
services and enhancements to existing product services, and marketing acceptance
of our product services. We cannot assure you that additional equity or debt
financing, if required, will be available on acceptable terms or at all.

YEAR 2000 COMPLIANCE

           Many computers, software, and other equipment are coded to accept
only two digit entries in the date code field. Beginning in the year 2000, these
code fields will need to accept four digit entries to distinguish between the
year 2000 and 21st century dates from other 20th century dates. As a result,
computer systems and/or software products used by many companies may need to be
upgraded to solve this problem.

           Assessment. The year 2000 problem affects the computers, software,
and other equipment that we use, operate or maintain for our operations.
Accordingly, we are in the process of evaluating our year 2000 readiness and
currently believe that our systems are compliant. We expect to be able to
resolve any significant year 2000 problems with third-party suppliers of
components; however we cannot assure you that these suppliers will resolve any
or all year 2000 problems before the occurrence of a material disruption to the
operation of our business. Any failure of these third parties to timely resolve
year 2000 problems with their systems could harm our business.

           Internal Infrastructure. We rely on the general communications
infrastructure maintained by the established telecommunications companies to
transmit our data to a NOC uplink site, to uplink to a satellite, and for
rebroadcast by the satellite to our customers. Accordingly, if the
telecommunications companies and satellite operators do not have their systems
year 2000 compliant, then we and our customers could suffer the consequences of
the failure of one or more components of the telecommunications infrastructure
in common with other users. The consequences could be that customers will refuse
to pay for our product services and we could suffer a decline in revenues. In
addition, costs would go up as we would seek to mitigate any problems.

           Systems other than information technology systems. In addition to
computers and related systems, software applications and telecommunications
systems, the operation of office and facilities equipment, such as fax machines,
telephone switches, security systems, and other common devices may be affected
by the year 2000 problem. We are currently assessing the potential effect and
costs of remediating the year 2000 problem on our office equipment and our
facilities.

           Product Services. We intend to evaluate our product services for year
2000 problems. To date, we are not aware of any problems with our existing
product services prior to releasing them to customers. We currently do not
expect any significant year 2000 problems to arise with our product services.

           We believe that we will not incur significant costs in connection
with any required modifications, upgrades or replacements of our internal
systems. We do not believe that the year 2000 problem will have a material
adverse effect on our business or operating results. In addition, we have not
deferred any material information technology projects as a result of our year
2000 problem activities.

           Most likely consequences of year 2000 problems. We expect to identify
and resolve all year 2000 problems that could adversely affect our business
operations. However, we believe that it is not possible to determine with
complete certainty that all year 2000 problems affecting us have been identified
and corrected. The number of devices that could be affected and the interactions
among these devices are simply too numerous. In addition, no one can predict the
how many year 2000 problem-related failures will occur or the severity, duration
or financial consequences of the year 2000 related failures. In general, we
believe that that any year 2000 problems will occur in the telecommunications
infrastructure. As a result, we believe that the following consequences are
possible:

           -    a significant number of operational inconveniences and
                inefficiencies for us, our contract manufacturers and our
                customers that will divert management's time and attention and
                financial resources from ordinary business activities;



                                      -12-
<PAGE>   15

           -    business disputes or penalties due to year 2000 related
                problems; and

           -    business disputes alleging that we failed to comply with the
                terms of contracts or industry standards of performance, some of
                which could result in litigation or contract termination.

           Contingency plans. We have only made generalized contingency plans
for year 2000 contingencies. If such problems occur which interrupt our services
to our customers, we intend to immediately seek to obtain such services from
telecommunications companies that are able to continue offering services. We may
also seek to replace on an accelerated basis, any affected equipment or
software. We may also have increased work hours for our personnel and hire
additional contract personnel to correct any year 2000 problems on an
accelerated basis.

           Disclaimer. The discussion of our efforts and expectations relating
to year 2000 compliance are forward-looking statements. Our ability to achieve
year 2000 compliance and the level of incremental costs associated therewith,
could be adversely affected by, among other things, availability and cost of
programming and testing resources third party suppliers' ability to modify
proprietary software, and unanticipated problems identified in the ongoing
compliance review.

                                  RISK FACTORS

           You should carefully consider the risks described below before making
an investment decision. The risks and uncertainties described below are not the
only ones we face. If any of the following risks actually occur, our business,
financial condition or results of operations could be materially and adversely
affected. In such case, the trading price of our common stock could decline, and
investors may lose all or part of their investment.

           This Form 10 Registration Statement also contains forward-looking
statements that involve risks and uncertainties. Our actual results could differ
materially from those anticipated in these forward-looking statements as a
result of certain factors, including the risks faced by us described below and
elsewhere herein.

WE HAVE A LIMITED OPERATING HISTORY

           Because we recently began operations, it is difficult to evaluate our
business and our prospects. Our revenue and income potential is unproven and our
business model is still emerging. We were incorporated on April 8, 1996 and did
not begin any activity until 1997 and have a limited operating history.
Furthermore, our prospects must be evaluated in light of the risks,
uncertainties, expenses and difficulties frequently encountered by companies in
the early stage of their development. We may not be successful in addressing
these risks and our business strategy may not be successful. These risks include
our ability to:

           -    develop new product services equal to or superior to those of
                our competitors;

           -    develop and maintain strong relationships with key customers;

           -    execute our sales and marketing strategy;

           -    expand our market share;

           -    expand our domestic and international operations;

           -    reduce our costs of equipment used to provide services;

           -    increase our gross margins;

           -    respond to competitive pressures; and

           -    continue to attract, retain and motivate highly qualified
                personnel, particularly in the areas of engineering, sales and
                marketing.

WE HAVE A HISTORY OF LOSSES AND EXPECT FUTURE LOSSES

           We have incurred losses since we commenced operations in April, 1996.
We incurred net losses of $2,539,237 in 1997, $3,549,096 in 1998 and $6,477,794
for the six months ended June 30, 1999. As of June 30, 1999 we had an
accumulated deficit of $12,566,127. We have not achieved profitability and we
cannot be certain that we will realize sufficient revenue to achieve
profitability. Even if we do achieve profitability, we cannot make any
assurances that we can sustain or increase profitability on a quarterly or
annual basis in the future. If revenue grows slower than we anticipate, if gross
margins do not improve or if operating expenditures exceed our expectations or
cannot adjust accordingly, we may continue to experience



                                      -14-
<PAGE>   17

significant losses on a quarterly basis. Accordingly, we are dependent upon the
successful completion of future capital infusions to continue operations. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."

WE EXPECT TO CONTINUE TO EXPERIENCE NEGATIVE CASH FLOW FROM OPERATIONS AND MAY
BE UNABLE TO MEET OUR FUTURE CAPITAL REQUIREMENTS THROUGH THE ISSUANCE OF
ADDITIONAL SECURITIES

           Since inception in April, 1996, we have experienced negative cash
flow from operations and we expect to continue to experience negative cash flow
from operations for the foreseeable future. Therefore, we have relied primarily
on issuances of equity securities to fund our operations to date. We currently
anticipate that our existing cash balances and net proceeds from recent equity
offerings will be sufficient to meet our anticipated needs for working capital
and capital expenditures through at least the next 12 months. We may need to
raise additional funds if our estimates of revenue, working capital and/or
capital expenditure requirements change or prove inaccurate or in order for us
to respond to unforeseen technological or marketing hurdles or to take advantage
of unanticipated opportunities. We cannot be certain that additional financing,
through the issuance of equity securities or otherwise, will be available to us
on favorable terms when required, or at all. Furthermore, if we raise additional
funds through the issuance of equity, equity-related or debt securities, such
securities may have rights, preferences or privileges senior to those of the
rights of our common and preferred stock and our stockholders may experience
additional dilution. If adequate funds are not available, or are not available
on acceptable terms, we may not be able to take advantage of market
opportunities, develop new product services or otherwise respond to competitive
pressures which could adversely affect our ability to achieve and sustain
positive cash flow and profitability in the future. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations."

OUR FINANCIAL RESULTS FROM PERIOD TO PERIOD MAY FLUCTUATE AS A RESULT OF SEVERAL
FACTORS, ANY OF WHICH COULD ADVERSELY AFFECT OUR STOCK PRICE

           We believe that period to period comparisons of our operating results
are not a good indication of our future performance. It is possible that in some
future periods our operating results may be below the expectations of public
market analysts and investors. In this event, the price of our common stock may
fall. Our revenue and operating results may vary significantly from period to
period due to a number of factors, many of which are not in our control. These
factors include:

           -    continued market acceptance of our product services;

           -    fluctuations in demand for our product services;

           -    variations in the timing of orders;

           -    the timing of new product and service introductions by us or our
                competitors;

           -    the mix of product services sold and the mix of distribution
                channels through which they are sold;

           -    our ability to obtain sufficient supplies of sole or limited
                source components for our product services;

           -    unfavorable changes in the prices of the components we purchase;

           -    our ability to achieve required cost reductions;

           -    our ability to attain and maintain quality levels for our
                product services; and



                                      -15-
<PAGE>   18

           -    our ability to integrate new technologies we develop or acquire
                into our product services.

           We cannot assure you that we will be able to sustain or improve our
gross margins in the future, or that we will be able to offset future price
declines with cost reductions. As a result, we may experience substantial period
to period fluctuations in future operating results and declines in gross
margins. A variety of factors affect our gross margins, including the following:

           -    the type of distribution channel through which we sell our
                product services;

           -    the volume of product services offered and sold;

           -    our product service sales mix;

           -    the average selling prices of our product services; and

           -    the effectiveness of our cost reduction efforts.

           We also anticipate that orders for our product services may vary
significantly from period to period. As a result, operating expenditures and
inventory levels in any given period could be disproportionately high. In some
circumstances, customers may delay purchasing our current product services in
favor of next-generation product services, which could affect our operating
results in any given period. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations" for detailed information on our
period to period operating results.

THE MARKET IN WHICH WE SELL OUR PRODUCT SERVICES IS INTENSELY COMPETITIVE AND
OUR BUSINESS WOULD BE ADVERSELY AFFECTED IF WE FAIL TO DEVELOP OR RETAIN MARKET
SHARE OR OTHERWISE FAIL TO SUCCESSFULLY COMPETE IN THIS MARKET

           Many of our competitors are substantially larger than we are and have
significantly greater financial, sales and marketing, technical, manufacturing
and other resources and more established distribution channels. These
competitors may be able to respond more rapidly to new or emerging technologies
and changes in customer requirements or devote greater resources to the
development, promotion and sale of their product services than we can.
Furthermore, some of our competitors may make strategic acquisitions or
establish cooperative relationships among themselves or with third parties to
increase their ability to rapidly gain market share by addressing the needs of
our prospective customers. These competitors may enter our existing or future
markets with solutions that may be less expensive, provide higher performance or
additional features or be introduced earlier than our solutions. Given the
market opportunity in the MSP market, we also expect that other companies may
enter our market with better product services and technologies. If any
technology that is competing with ours is more reliable, faster, less expensive
or has other advantages over our technology, then the demand for our product
services would decrease, which would seriously harm our business.

           We expect our competitors to continue to improve the performance of
their current product services and introduce new product services or new
technologies as industry standards and customer requirements evolve that may
supplant or provide lower cost alternatives to our product services. Successful
new product service introductions or enhancements by our competitors could
reduce the sales or market acceptance of our product services, perpetuate
intense price competition or make our product services obsolete. To be
competitive, we must continue to invest significant resources in research and
development, sales and marketing and customer support. We cannot be sure that we
will have sufficient resources to make such investments or that we will be able
to make the technological advances necessary to be competitive. As a



                                      -16-
<PAGE>   19

result, we may not be able to compete effectively against our competitors. Our
failure to maintain and enhance our competitive position within the market may
seriously harm our business.

           Increased competition is likely to result in price reductions,
reduced gross margins, longer sales cycles and loss of market share, any of
which would seriously harm our business and results of operations. We cannot be
certain that we will be able to compete successfully against current or future
competitors or that competitive pressures will not seriously harm our business.

IF WE FAIL TO ENHANCE OUR EXISTING PRODUCT SERVICES OR DEVELOP AND INTRODUCE NEW
PRODUCT SERVICES AND FEATURES IN A TIMELY MANNER TO MEET CHANGING CUSTOMER
REQUIREMENTS AND EMERGING INDUSTRY STANDARDS, OUR ABILITY TO GROW OUR BUSINESS
WILL SUFFER

           The MSP market is characterized by rapidly changing technologies and
short product life cycles. Our future success will depend in large part upon our
ability to:

           -    identify and respond to emerging technological trends in the
                market;

           -    develop and maintain competitive product services;

           -    enhance our product services by adding innovative features that
                differentiate our product services from those of our
                competitors;

           -    bring product services to market on a timely basis at
                competitive prices;

           -    respond effectively to new technological changes or new product
                service announcements by others; and

           -    respond to emerging broadband access technologies such as DSL,
                wireless and cable modems.

           We will not be competitive unless we continually introduce new
product services and product service enhancements that meet these emerging
standards. In the future we may not be able to effectively address the
compatibility and interoperability issues that arise as a result of
technological changes and evolving industry standards.

           The technical innovations required for us to remain competitive are
inherently complex, require long development cycles and are dependent in some
cases on sole source suppliers. We will be required to continue to invest in
research and development in order to attempt to maintain and enhance our
existing technologies and product services, but we may not have the funds
available to do so. Even if we have sufficient funds, these investments may not
serve the needs of customers or be compatible with changing technological
requirements or standards. Most development expenses must be incurred before the
technical feasibility or commercial viability of new or enhanced product
services can be ascertained. Revenue from future product services or product
service enhancements may not be sufficient to recover the associated development
costs.

WE DEPEND ON OUR KEY PERSONNEL WHO MAY NOT CONTINUE TO WORK FOR US

           Our future success depends in large part upon the continued services
of our key technical, sales and senior management personnel, none of whom is
bound by an employment agreement. The loss of any of our senior management or
other key research, development, sales and marketing personnel, particularly if
lost to competitors, could harm our business. In particular, the services of
Edward Tan, President and Chief Executive Officer, Ronald Everoski, Chief
Technical Officer and Vice President of Research and



                                      -17-
<PAGE>   20

Development and Douglas Hanson, Vice President of Sales and Marketing, would be
difficult to replace. We do not maintain "key person" life insurance for any of
our personnel. See "Directors and Executive Officers" for more detailed
information on our key personnel.

IF WE ARE NOT SUCCESSFUL IN EXPANDING OUR BUSINESS IN INTERNATIONAL MARKETS, OUR
GROWTH WILL SUFFER

           We intend to expand our operations domestically and internationally,
and will seek to expand the range of our product services and penetrate new
geographic markets; however, we have no experience in effectuating rapid
expansion or in managing operations which are geographically dispersed. Although
we believe we have an adequate infrastructure, there can be no assurance that
our current management, personnel and other corporate infrastructure will be
adequate to manage our growth.

           As part of our strategy to address the global needs of our customers
and partners, we have committed significant resources to expanding our
international sales and support channels in advance of revenue. We cannot assure
you that our efforts to develop international sales and support channels will be
successful. Moreover, international sales are subject to a number of risks,
including changes in foreign government regulations and communications
standards, export license requirements, tariffs and taxes, other trade barriers,
difficulty in collecting accounts receivable, difficulty in managing foreign
operations, and political and economic instability. To the extent our customers
may be impacted by currency devaluations or general economic crises, the ability
of these customers to purchase our product services could be adversely affected.
Payment cycles for international customers are typically longer than those for
customers in the United States. We cannot assure you that foreign markets for
our product services will not develop more slowly than currently anticipated. In
addition, if the relative value of the U.S. dollar in comparison to the currency
of our foreign customers should increase, the resulting effective price increase
of our product services to these foreign customers could result in decreased
sales.

           We anticipate that our foreign sales will generally be invoiced in
U.S. dollars and, accordingly, we do not currently plan to engage in foreign
currency hedging transactions. However, as we expand our international
operations, we may allow payment in foreign currencies and exposure to losses in
foreign currency transactions may increase. We may choose to limit any currency
exposure through the purchase of forward foreign exchange contracts or other
hedging strategies. We cannot assure you that any currency hedging strategy we
may adopt would be successful in avoiding exchange-related losses.



                                      -18-
<PAGE>   21

OUR PRODUCT SERVICES MUST COMPLY WITH COMPLEX GOVERNMENT REGULATIONS WHICH MAY
PREVENT US FROM SUSTAINING OUR REVENUE OR ACHIEVING PROFITABILITY

           In the United States, our product services must comply with various
regulations and standards defined by the Federal Communications Commission and
Underwriters Laboratories. Internationally, product services that we develop may
be required to comply with standards established by telecommunications
authorities in various countries as well as with recommendations of the
International Telecommunications Union. If we fail to obtain timely domestic or
foreign regulatory approvals or certificates, we would not be able to sell our
product services where these regulations apply, which may prevent us from
sustaining our revenue or achieving profitability.

IF INTERNET USAGE DECLINES OR THE INTERNET INFRASTRUCTURE IS NOT ADEQUATELY
MAINTAINED AND EXPANDED, DEMAND FOR OUR PRODUCT SERVICES MAY DECLINE

           The Internet has recently begun to develop and is rapidly evolving.
As a result, the commercial market for product services designed to enable
high-speed access to the Internet has only recently begun to develop. Our
success will depend in large part on increased use of the Internet and other
networks based on Internet protocol by corporate telecommuters and small
offices. Critical issues concerning the commercial use of the Internet remain
unresolved and are likely to affect the development of the market for our
product services. These issues include security, reliability, cost, ease of
access, government regulation and quality of service. The adoption of the
Internet for commerce and communications, particularly by enterprises that have
historically relied upon alternative means of commerce and communications,
generally requires the acceptance of a new method of conducting business and
exchanging information. The recent growth in the use of the Internet has caused
frequent periods of performance degradation that have prompted efforts to
upgrade the Internet infrastructure. Any perceived degradation in the
performance of the Internet as a whole could undermine the benefits of our
product services. Potentially increased performance and other benefits provided
by our product services and the product services of others are ultimately
limited by, and are reliant upon, the speed and reliability of the Internet
backbone itself. Consequently, the emergence and growth of the market for our
product services will depend on improvements being made to the entire Internet
infrastructure to alleviate overloading and congestion.

IF WE ARE UNABLE TO ADEQUATELY PROTECT OUR INTELLECTUAL PROPERTY RIGHTS OTHER
COMPANIES MAY USE OUR INTELLECTUAL PROPERTY TO DEVELOP COMPETITIVE PRODUCT
SERVICES THAT MAY REDUCE DEMAND FOR OUR PRODUCT SERVICES

           We currently rely on a combination of copyright, trademark and trade
secret laws and restrictions on disclosure to protect our intellectual property
rights. We have two pending U.S. trademark applications.

           We also enter into confidentiality or license agreements with our
employees, consultants and corporate partners, and control access to and
distribution of our software, documentation and other proprietary information.
Despite our efforts to protect our proprietary rights, unauthorized parties may
attempt to copy or otherwise obtain and use our product services or technology.
We cannot assure you that these precautions will prevent misappropriation or
infringement of our intellectual property. Monitoring unauthorized use of our
product services is difficult, and we cannot assure you that the steps we have
taken will prevent misappropriation of our technology, particularly in foreign
countries where the laws may not protect our proprietary rights as fully as in
the United States.



                                      -19-
<PAGE>   22

WE MAY BE SUBJECT TO INTELLECTUAL PROPERTY INFRINGEMENT CLAIMS THAT ARE COSTLY
TO DEFEND AND COULD LIMIT OUR ABILITY TO USE CERTAIN TECHNOLOGIES IN THE FUTURE

           Our industry is characterized by the existence of a large number of
patents and frequent claims and related litigation regarding patent and other
intellectual property rights. In particular, leading companies in the data
communications and networking markets have extensive patent portfolios with
respect to modem and networking technology. From time to time, third parties,
including these leading companies, have asserted and may assert exclusive
patent, copyright, trademark and other intellectual property rights to
technologies and related standards that are important to us. We expect that we
may increasingly be subject to infringement claims as the numbers of product
services and competitors in the small office market for shared Internet access
solutions grow and the functionality of product services overlaps.

           We may in the future initiate claims or litigation against third
parties for infringement of our proprietary rights to determine the scope and
validity of our proprietary rights. Any such claims, with or without merit,
could be time-consuming, result in costly litigation and diversion of technical
and management personnel, or require us to develop non-infringing technology or
enter into royalty or licensing agreements. Such royalty or licensing
agreements, if required, may not be available on acceptable terms, if at all. In
the event of a successful claim of infringement and our failure or inability to
develop non-infringing technology or license the proprietary rights on a timely
basis, our business would be harmed.

WE FACE A NUMBER OF UNKNOWN RISKS ASSOCIATED WITH TRYING TO BECOME YEAR 2000
COMPLIANT

           Some computers, software, and other equipment include computer code
in which calendar year data is abbreviated to only two digits. As a result of
this design decision, some of these systems could fail to operate or fail to
produce correct results if "00" is interpreted to mean 1900, rather than 2000.
As a result, computer systems and software used by many companies and
governmental agencies may need to be upgraded to comply with year 2000
requirements or risk system failure or miscalculations causing disruptions of
normal business activities. These problems are widely expected to increase in
frequency and severity as the year 2000 approaches, and are commonly referred to
as the "year 2000 problem." We have just begun to identify measures to address
the issues arising from the year 2000 problem and therefore the risks associated
with being year 2000 compliant are unknown. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Year 2000
Compliance."

INSIDERS HAVE SUBSTANTIAL CONTROL OVER AMERICAN MULTIPLEXER CORPORATION THAT
COULD DELAY OR PREVENT A CHANGE IN OUR CORPORATE CONTROL

           Our executive officers, and directors and their affiliates will, in
the aggregate, own approximately 24% our outstanding common stock. As a result,
our officers, directors and affiliates will have the ability to influence the
election of our board of directors and the outcome of corporate actions
requiring stockholder approval. This concentration of ownership may have the
effect of delaying or preventing a change in our corporate control. We do not
have cumulative voting in the election of directors; and the minority
shareholders will not be able to elect any director to our Board of Directors.

FUTURE SALES OF OUR COMMON STOCK MAY CAUSE OUR STOCK PRICE TO DECLINE

           Sales of a substantial number of shares of common stock after this
offering could adversely affect the market price of our common stock and could
impair our ability to raise capital through the sale of additional equity
securities. As of June 30, 1999 we had 37,353,566 shares of common stock
outstanding.



                                      -20-
<PAGE>   23

WE MAY HAVE INSUFFICIENT CAPITAL FOR FUTURE OPERATIONS

           We anticipate, based on current proposed plans and assumptions
relating to its operations, that current cash reserves, together with projected
cash flow from operations, will be sufficient to satisfy our contemplated cash
requirements through the fourth quarter of 2000. Thereafter, we will require
substantial additional financial resources to fund our operations. The expansion
into new product areas will also require substantial financial funding. The
failure to acquire additional funding when required will have a material adverse
effect on the our business prospects.

WE FACE OBSTACLES RELATING TO MARKET ACCEPTANCE AND DISTRIBUTION

           We are at an early stage of development and our earnings growth
depends primarily upon market acceptance of our product services. There can be
no assurance that our product service development efforts will progress further
with respect to any potential new product services or that they will be
successfully completed. In addition, there can be no assurance that our
potential new product services will be capable of being produced in commercial
quantities at reasonable costs or that these potential product services, if
introduced, will be successfully marketed or will achieve customer acceptance.

           We do not have sufficient experience in marketing our product
services to determine the optimum distribution methods. Accordingly, we might be
in a position requiring change in our sales, distribution, and marketing
strategies and implementation.

WE WILL BE DEPENDENT ON NEW PRODUCTS AND PRODUCT ENHANCEMENT INTRODUCTIONS,
PRODUCT DELAYS MAY NEGATIVELY AFFECT OUR BUSINESS

           Our success in our business depends on, among other things, the
timely introduction of successful new product services or enhancements of
existing product services to replace declining revenues from product services at
the latter stage of a product service cycle. Consumer preferences for product
services are difficult to predict, and few product services achieve sustained
market acceptance. If revenues from new product services or enhancements do not
replace declining revenues from existing product services, our business,
operating results and financial condition could be materially adversely
affected. The process of developing broadband services is extremely complex and
is expected to become more complex. A significant delay in the introduction of
one or more new product services or enhancements could have a material adverse
effect on our ultimate success of such product services and on our business,
operating results and financial condition.

WE ARE PARTICIPATING IN A DEVELOPING MARKET, NEW ENTRANTS MAY DOMINATE THE
MARKET SEGMENT

           The MSP market is rapidly evolving and is characterized by an
increasing number of market entrants who have introduced or developed product
services. Although we currently believe that the diverse segments of the market
will provide opportunities for more than one supplier of product services
similar to ours, it is possible that a single supplier may dominate one or more
market segment.

WE FACE SUBSTANTIAL COMPETITION FROM OTHER COMPANIES

           We compete with many other companies. We will face competition from
numerous sources, including terrestrial and satellite-based online and Internet
service providers and others with the technical capabilities and expertise which
would encourage them to develop and commercialize competitive product services.
Certain of such competitors have substantially greater financial, technical,
marketing, distribution, personnel and other resources than we do. Increased
competition, resulting from, among other things, the timing of competitive
product service releases and the similarity of such product services to ours,
may result in significant price competition, any of which could have a material
adverse effect on our business, operating



                                      -21-
<PAGE>   24

results or financial condition. Current and future competitors with greater
financial resources than we have may be able to undertake more extensive
marketing campaigns, adopt more aggressive pricing policies and make higher
offers or guarantees to partners and customers than we can. There can be no
assurance that we will have the resources required to respond effectively to the
market or technological changes or to compete successfully with current or
future competitors or that competitive pressures we face will not materially and
adversely affect our business, operating results or financial condition.

ITEM 3. PROPERTIES.

           The Company is headquartered in Sunnyvale, California, where it
leases approximately 12,400 square feet of space in a single building. The lease
for the Company's facility expires on November 30, 2003 and the Company has an
option to extend the term for an additional five year period at such time,
provided that it is not then in default of any material provisions of its lease.
The Company believes that its facility provides adequate space for its
anticipated needs.

ITEM 4. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT.

           The following table sets forth certain information with respect to
the beneficial ownership of the Company's voting stock as of June 30, 1999 by
(i) all persons known by the Company to beneficially own more than 5% of any
class of the Company's voting securities, (ii) each director and Named Executive
Officer of the Company and (iii) all directors and executive officers of the
Company as a group. As of June 30, 1999, the Company had outstanding 200,000
shares of Series A Preferred Stock and 37,353,566 shares of common stock.

           Beneficial ownership is determined in accordance with the rules of
the Securities and Exchange Commission and includes voting or investment power
with respect to the securities. The address for each listed director and officer
is c/o American Multiplexer Corporation, 575 North Pastoria Avenue, Sunnyvale,
California 94086. Except as indicated by footnote, and subject to applicable
community property laws, the persons named in the table have sole voting and
investment power with respect to all shares of stock shown as beneficially owned
by them. The number of shares of common stock outstanding used in calculating
the percentage for each listed person includes the shares of common stock
underlying options or warrants held by such person that are exercisable within
60 days of June 30, 1999, but excludes shares of common stock underlying options
or warrants held by any other person.

held on all matters upon which shareholders have the right to vote. The
Company's common shareholders are entitled to such dividends as may be declared
from time to time by the board of directors out of funds legally available for
that purpose. Upon a dissolution, the Company's common shareholders are entitled
to share pro rata in our assets remaining after payment in full of all of our
liabilities and obligations, including payment of the liquidation preference if
any, of any preferred stock then outstanding.

           The Company's common shareholders have dissenters' rights to
appraisal with respect to their shares as provided by statute in connection with
certain types of merger or share exchange transactions. Dissenters' rights are
also available with respect to certain sales of all or substantially all of our
property and certain amendments to our articles of incorporation that materially
and adversely affect certain enumerated rights of a dissenter's shares. The
Company's common shareholders do not have any preemptive rights, redemption
privileges, sinking fund privileges or conversion rights.

PREFERRED STOCK

           The Company's preferred shareholders receive one vote for each
preferred share held on all matters upon which the Company's shareholders have
the right to vote. The Company's preferred shareholders are entitled to receive,
in addition to all dividends offered to holders of the Company's common stock,
when, if and as declared by the Board of Directors, out of funds legally
available therefore and in preference to any dividends on common stock: (i) in

shall accrue to holders of preferred stock until declared by the Board of
Directors. Each share of the Company's preferred stock is convertible at any
time, at the option of the holder thereof, into two (2) shares of the Company's
common stock.

           The Company's Articles of Incorporation provide that the Company's
directors shall not have personal liability arising out of action by or in the
right of the Company or otherwise for monetary damages for breach of any duty as
a director; except as to (i) acts or omissions that such director at the time of
such breach knew of believed were clearly in conflict with the best interests of
the Company, (ii) any liability under Section 55-8-33 of the North Carolina
Business Corporation Act (the "NCBCA") or any successor provision, (iii) any
transaction from which such director derived an improper personal benefit, or
(iv) acts or omissions occurring prior to the date of the effectiveness of the
Articles of Incorporation. "Improper personal benefit" is defined so as not to
include a director's reasonable compensation or other reasonable incidental
benefit for or on account of his or her services as a director, officer,
employee, independent contractor, attorney, or consultant of the Company.

           In general, Sections 55-8-50 through 55-8-58 of the NCBCA allow a
corporation to indemnify its directors, officers, employees or agents under
nonexclusive statutory and nonstatutory schemes of indemnification. Under the
statutory scheme, a corporation may, with certain exceptions, indemnify a



                                      -29-

director, officer, employee or agent of the corporation who was, is, or is
threatened to be made, a party to any threatened, pending, or completed legal
action, suit or proceeding, whether civil, criminal, administrative or
investigative, because of the fact that such person is or was a director,
officer, agent or employee of the corporation, or is or was serving at the
request of the corporation as a director, officer, employee or agent of another
corporation or enterprise. This indemnity may include the obligation to pay any
judgment, settlement, penalty, fine (including an excise tax assesses with
respect to an employee benefit plan) and reasonable expenses incurred in
connection with a proceeding (including counsel fees), but no such
indemnification may be granted unless such director, officer, agent or employee
(i) conducted himself in good faith, (ii) reasonably believed (x) that any
action taken in his official capacity with the corporation was in the best
interest of the corporation or (y) that in all other cases his conduct at least
was not opposed to the corporation's best interest, and (iii) in the case of any
criminal proceeding, had no reasonable cause to believe his conduct was
unlawful. Whether a director has met the requisite standard of conduct for the
type of indemnification set forth above is determined by the board of directors,
a committee of directors, special legal counsel or the shareholders in
accordance with Section 55-8-55. A corporation may not indemnify a director
under the statutory scheme in connection with a proceeding by or in the right of
the corporation in which the director was adjudged liable to the corporation or
in connection with a proceeding in which a director was adjudged liable on the
basis of having received an improper personal benefit.

           Section 55-8-57 of the NCBCA permits a corporation to include in its
articles of incorporation or bylaws a provision indemnifying any of its
directors, officers, employees or agents against liability and expenses
(including attorneys' fees) in any proceeding (including proceedings brought by
or on behalf of the corporation) arising out of their status as such or their
activities in any of the foregoing capacities; provided, however, that a
corporation may not indemnify or agree to indemnify a person against liability
or expenses such person may incur on account of activities that were clearly in
conflict with the best interests of the corporation. The Company's bylaws
provide for indemnification to the fullest extent permitted under the NCBCA.

           Sections 55-8-52 and 55-8-56 of the NCBCA require a corporation,
unless its articles of incorporation provide otherwise, to indemnify a director
or officer who has been wholly successful, on the merits or otherwise, in the
defense of any proceeding to which such director or officer was a party. Unless
prohibited by the Articles of Incorporation, a director or officer also may make
application and obtain court-ordered indemnification if the court determines
that such director or officer is fairly and reasonably entitled to such
indemnification as provided in Sections 55-8-54 and 55-8-56. The Company's
Articles of Incorporation do not contain any prohibition of this type of
indemnification.

           Section 55-8-57 of the NCBCA provides that a corporation may purchase
and maintain insurance on behalf of any individual who is or was a director,
officer, employee or agent of the corporation against certain liabilities
incurred by such persons, whether or not the corporation is otherwise authorized
by the NCBCA to indemnify such party. Our directors and officers are not
currently covered under such directors' and officers' insurance policies.

           The foregoing summaries of North Carolina law dealing with
indemnification of directors and officers are not intended to be complete
descriptions of the relevant statutory provisions. They are qualified in their
entirety by reference to Sections 55-8-50 through 55-8-58 of the NCBCA, which
contain the specific indemnification provisions.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

Board of Directors
American Multiplexer Corporation

           We have audited the accompanying balance sheets of American
Multiplexer Corporation (a development stage company), successor to Temasek
Telephone, Inc., as of December 31, 1997 and 1998 and the related statements of
operations, stockholders' equity and cash flows for each of the three years in
the period ended December 31, 1998, and for the period January 1, 1997 through
December 31, 1998. 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 American Multiplexer
Corporation (a development stage company), successor to Temasek Telephone, Inc.,
as of December 31, 1997 and 1998, and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 1998, and for
the period January 1, 1997 through December 31, 1998, in conformity with
generally accepted accounting principles.

                          NOTES TO FINANCIAL STATEMENTS

                           December 31, 1998 and 1997
           (information relating to the period January 1, 1999 through
                           June 30, 1999 is unaudited)

NOTE A - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

           American Multiplexer Corporation (the "Company"), a development stage
company, was incorporated on April 16, 1996 and had no activities through
December 31, 1996. In January 1997, the Company commenced operations through the
issuance of 17,919,802 shares of common stock in exchange for certain assets and
rights to the product, the MUX-6 Multiplexer. The Multiplexer was designed to
expand underground cable capacity by allowing six different telephone numbers to
be carried on a single pair of copper wire. In 1998, the Company abandoned the
marketing of the MUX-6 Multiplexer and has refocused its efforts in the area of
satellite communications.

           The Company is now a Multimedia Service Provider ("MSP") that will
provide high speed Internet access and broadband interactive services for
consumers through the SatExpress network via Internet Service Providers
("ISP's").

           A summary of the Company's significant accounting policies follows:

Basis of Presentation

With the acquisition of certain assets and rights of the product, the MUX-6,
Temasek Telephone, Inc. was deemed to be a predecessor corporation, and
accordingly, their statements of operations and cash flows for the year ended
December 31, 1996 are included in these financial statements.

The accompanying financial statements have been prepared in conformity with
generally accepted accounting principles, which contemplate continuation of the
Company as a going concern. However, the Company is a development stage company
and has not generated any revenues and has net losses since inception through
December 31, 1998 and such losses continued through the unaudited six-month
period ended June 30, 1999. Subsequent to December 31, 1998, the Company issued
shares of common and preferred stock resulting in net proceeds of approximately
$24,000,000. The Company's continued existence is ultimately dependent upon its
ability to use the funds to develop and market the SatExpress network and the
success of future operations. There can be no assurance that the Company will
achieve profitability or positive cash flow from operations.

Cash and Cash Equivalents

              All liquid investments instruments with an original maturity of
   three months or less are considered cash and cash equivalents.

              The Company maintains cash balances at financial institutions,
   which are insured by the Federal Deposit Insurance Corporation up to
   $100,000. The Company has not experienced any losses in such cases and
   believes it is not exposed to significant risk or loss.

                           June 30, 1999 is unaudited)


NOTE A - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Inventory

           Inventory is stated at the lower of cost (first-in, first-out method)
or market. All inventory as of December 31, 1998, was reduced to salvage value
as it related to products that are no longer being developed.

Property and Equipment

           Property and equipment are recorded at cost and are depreciated on a
straight-line basis over their estimated lives of three to ten years. All
capital expenditures less than $500 are expensed as incurred. Maintenance and
repairs are charged to operations as incurred.

Research and Development

           Research and development costs are expensed as incurred.

Income Taxes

           Income taxes are accounted for under the liability method. Under this
method, deferred tax assets and liabilities are determined based on differences
between the financial statement carrying amounts of existing assets and
liabilities and their respective tax basis. Deferred tax assets and liabilities
are measured using current enacted tax rates. A valuation allowance is
established if it is more likely than not that some portion or all of the
deferred tax assets will not be realized.

Fair Value of Financial Instruments

The fair value of cash, accounts receivable, notes receivable, accounts payable
and accrued liabilities approximate carrying value due to the short-term nature
of such instruments.

Long-Lived Assets

The Company has adopted Statement of Financial Accounting Standards ("SFAS") No.
121, Accounting For The Impairment of Long-Lived Assets and For Long-Lived
Assets To Be Disposed Of, which requires that long-lived assets and certain
identifiable intangibles be reviewed for impairment whenever events or changes
indicate that the carrying amount of an asset may not be recoverable. The
Company's policy is to review the recoverability of all intangible assets at a
minimum on an annual basis, and in addition whenever events or changes indicate
that the carrying amount of an asset may not be recoverable.

                    NOTES TO FINANCIAL STATEMENTS (continued)

                           December 31, 1998 and 1997
           (information relating to the period January 1, 1999 through
                           June 30, 1999 is unaudited)


NOTE A - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Basic and Diluted Net Loss Per Share

           Basic loss per share is computed by dividing net income by the
weighted average common shares outstanding for the period. Diluted loss per
share reflects the potential dilution that could occur if securities or other
contracts to issue common stock were exercised or converted into common stock.
However, due to the Company's' net loss position for all periods presented,
diluted loss per share excludes common equivalent shares, as their effect is
anti-dilutive. The weighted average common shares outstanding used to compute
net loss per share for the year ended December 31, 1996 was based on the shares
issued in January 1997 in exchange for the net assets acquired.

Stock-Based Compensation

           The Company accounts for stock-based awards to employees using the
intrinsic value method in accordance with Accounting Principle Board Opinion No.
25, "Accounting For Stock Issued to Employees."

Stock Pricing

           All per share sales prices for the Company's common and preferred
stock were approved by the Board of Directors of the Company.

Recently Issued Accounting Standards

           In June 1997, the Financial Accounting Standards Board ("FASB")
issued SFAS No. 130, "Reporting Comprehensive Income," which requires an
enterprise to report, by major components and as a single total, the change in
its net assets during the period from non-owned sources and SFAS No. 131,
"Disclosures About Segments of an Enterprise and Related Information," which
establishes annual and interim reporting standards for an enterprise's business
segments and related disclosures about its products, services, geographic areas
and major customers. The Company has no comprehensive income items to report for
the period from January 1, 1997 (inception) to December 1998, or for the
six-month period ended June 30, 1999. The Company currently has no reportable
segments under SFAS No. 131.

           In June 1998, the FASB issued SFAS No. 133, "Accounting for
Derivative Instruments and Hedging Activities," which defines derivatives,
requires that all derivatives be carried at fair value, and provides for hedge
accounting when certain conditions are met. SFAS No. 133, as amended by SFAS No.
137, is effective for the Company in fiscal 2002. Although the Company has not
fully assessed the implications of SFAS Nos. 133 and 137, the Company does not
believe that the adoption of this statement will have a material impact on the
Company's financial position or results of operations.

Use of Estimates

           In preparing financial statements in conformity with generally
accepted accounting principles, management is required to make estimates and
assumptions that affect the reported amounts of assets and

NOTE C - PURCHASE OF CERTAIN ASSETS

           During November 1998, the Company purchased certain assets from a
company that was controlled by the courts under Chapter 7 bankruptcy
proceedings. The total purchase price was $805,000. Of this amount, $505,000 was
paid in November 1998, and the balance was paid by June 30, 1999. The purchase
price was allocated among equipment, furniture and in-process research and
development.

           At the time of purchase, the Company determined that the
technological feasibility of the purchased research and development had not yet
been established and that such technology had no future alternative uses. As
such, the Company expensed all of the purchased in-process research and
development.

           At December 31, 1998, the Company had federal and state net operating
loss carryforwards of approximately $5,845,000 and $2,922,000, respectively,
available to offset future taxable income. The Company's federal and state net
operating loss carryforwards expire through 2018 and 2003, respectively.

           The Tax Reform Act of 1986 limits the use of net operating loss and
tax credit carryforwards in certain situations where changes occur in the stock
ownership of a company. If the Company should have an ownership change, as
defined, utilization of the carryforwards could be restricted.

NOTE E - RELATED PARTY TRANSACTIONS

           An interest free demand note receivable, in the amount of $100,000,
was issued to a stockholder on June 5, 1997. The outstanding balance of the note
was $100,000 at December 31, 1997. The note was repaid during 1998.

           A demand note receivable, in the amount of $125,000, was issued to a
stockholder on November 30, 1998. The note was repaid in January 1999.

           In March 1999, a demand note receivable in the amount of $250,000,
bearing interest at 9% per annum, was issued to a stockholder.

           In June 1999, the Company loaned a stockholder of the Company the sum
of $3,375,000. The amount due is in the form of a note receivable that is due
and payable, with interest, on December 31, 1999. The note bears interest at 9%
per annum. Certain of the funds were used to purchase common stock of the
Company. Accordingly, the note receivable from shareholder at June 30, 1999 has
been included in stockholders' equity.

NOTE F - PREFERRED STOCK

           The Company has authorized the issuance of 10,000,000 shares of
Series A Preferred Stock ("the Preferred shares"). The Preferred shares have no
par value and may be converted into two shares of the Company's common stock at
any time subsequent to issuance. The Preferred shares are entitled to cumulative
dividends, payable only when, if and as declared by the Board of Directors of
the Company, which are cumulative, at a rate of $1.50, $2.50 and $3.50 per share
for the years ending December 31, 2000, 2001 and 2002, respectively.
Additionally, Preferred shareholders are entitled to the full amount of any
common stock dividends. The preferred shares have full voting privileges with
regard to matters submitted to the shareholders for a vote and, with proper
notice, have the right to cumulate votes for the election of Directors of the
Company. In calculating the loss per share effect of the preferred dividends,
the total of all cumulative dividends have been allocated over the period from
the date of issuance through December 31, 2002.

NOTE G - STOCK WARRANTS

           In November 1998 the Company issued warrants for the purchase of
3,000,000 shares of common stock to three employees of the Company. The exercise
price of each warrant is $1.00 per share of common stock. Warrants to purchase
1,500,000 shares of common stock that are exercisable upon the Company's common
stock price reaching certain price levels and warrants to purchase 1,500,000
shares of common stock are exercisable upon the Company reaching certain
milestones related to the development and marketing of certain product lines and
service. Once the contingencies have been satisfied, the warrants can be
exercised over three years. These warrants will be accounted for under variable
plan accounting.

           In May 1999, the Company issued warrants to purchase 6,000,000 shares
of common stock to an officer of the Company. Each warrant entitles the holder
to purchase one share of common stock at $5.06 per share, which is equal to the
fair value per share of common stock at the date of issue. The warrants are
exercisable at any time through May 14, 2004.

NOTE H - STOCK OPTION PLAN

           In February 1999, the Board of Directors approved a stock option plan
(the "Plan") intended to qualify as an incentive stock option plan as defined in
Section 422 of the Internal Revenue Code. The Plan is accounted for under the
provisions of APB No. 25 and generally provides that exercise prices will not be
less than fair market value per share on the date the option is granted. Options
granted prior to adoption of the Plan were issued at fair market value.
Therefore, no compensation cost has been recognized for the options granted. The
options are exercisable cumulatively, to the extent of 25% on the one-year
anniversary date and an additional 1/36 on the last day of each calendar month.

           Had compensation cost for the options granted been determined based
on the fair value of the options at the grant dates consistent with the method
prescribed in SFAS No. 123, Accounting for Stock-Based Compensation, the
Company's net losses would have been increased to the pro forma amounts
indicated below.

NOTE I - RETIREMENT PLAN

             On January 1, 1999, the Company adopted the AMC 401(k) Plan (the
"Plan") which is a standardized profit sharing and trust under section 401(k) of
the Internal Revenue Code. The Plan allows for employees with at least six
months of service, to contribute to the Plan the maximum amount of salary as
permitted under Section 401(k). The Company may make discretionary contributions
to the Plan. All such contributions are 100% vested at the time the contribution
is made. Employees can borrow against their account balances for hardship or
financial necessity for a minimum of $1,000 and a maximum of $50,000. Upon the
retirement age of 60, employees receive a lump sum distribution of their account
value.

NOTE J - COMMITMENTS

           The Company is presently leasing office space under leases expiring

shall be located at such place, within or without the State of North Carolina,
as shall be determined from time to time by the Board of Directors and as shall
have been so designated most recently in the annual report of the Corporation
or amendment thereto, filed with the North Carolina Secretary of State pursuant
to the North Carolina Business Corporation Act.

        Section 1.2 REGISTERED OFFICE. The Corporation shall maintain a
registered office in the State of North Carolina as required by law, which may
be, but need not be, identical with the principal office.

        Section 1.3 OTHER OFFICES. The Corporation may have offices at such
other places, either within or without the State of North Carolina, as the
Board of Directors may from time to time determine, or as the affairs of the
Corporation may require.

                                   ARTICLE II

                            MEETINGS OF SHAREHOLDERS

        Section 2.1 PLACE OF MEETINGS. All meetings of shareholders shall be
held at the principal office of the Corporation, or at such other place, either
within or without the State of North Carolina, as shall be designated by the
Board of Directors or the Chief Executive Officer of the Corporation.

        Section 2.2 ANNUAL MEETINGS. The annual meeting of the shareholders
shall be held each year at such date and time as shall be designated by the
Board of Directors or the Chief Executive Officer of the Corporation, for the
purpose of electing directors of the Corporation and for the transaction of
such other business as may be properly brought before the meeting.

        Section 2.3 SUBSTITUTE ANNUAL MEETING. If the annual meeting shall not
be held on the day provided for by these Bylaws, a substitute meeting may be
called in accordance with the provisions of Section 2.4. A meeting so called
shall be designated and treated for all purposes as the annual meeting.

<PAGE>   2
     Section 2.4 SPECIAL MEETINGS. Special Meetings of the shareholders may be
called at any time by or at the request of the Chief Executive Officer or the
Board of Directors. Unless the Corporation is a "public corporation" (as defined
in the North Carolina Business Corporation Act), a special meeting of the
shareholders shall also be called upon the written demand or demands of the
holders of at least ten percent (10%) of all votes entitled to be cast on any
issue proposed to be considered at such meeting pursuant to such demand or
demands, provided such demand or demands describe the purpose or purposes for
which said special meeting is to be held and are signed, dated and delivered to
the Secretary of the Corporation. Notice of a special meeting called at the
demand of shareholders shall be given within thirty (30) days after the date of
receipt by the Secretary of the demand or demands requiring the call of such
special meeting.

     Section 2.5 NOTICE OF MEETINGS. Written or printed notice stating the
date, time and place of the meeting shall be given not less than ten (10) nor
more than sixty (60) days before the date thereof, either personally or by
mail, at the direction of the person or persons calling the meeting, to each
shareholder entitled to vote at such meeting and each other shareholder
entitled to notice pursuant to the Articles of Incorporation or applicable law.

     In the case of a special meeting, the notice of meeting shall specifically
state the purpose or purposes for which the meeting is called. In the case of
an annual meeting, the notice of meeting need not specifically state the
purpose or purposes thereof or the business to be transacted thereat unless
such statement is expressly required by the provisions of these Bylaws or by
applicable law.

If a meeting is adjourned for 120 days after the date fixed for the original
meeting, or if a new record date is fixed for the adjourned meeting, or if the
date, time and place for the adjourned meeting is not announced prior to
adjournment, then notice of the adjourned meeting shall be given as in the case
of an original meeting; otherwise, it is not necessary to give any notice of
the adjourned meeting other than by announcement at the meeting at which the
adjournment is taken.

     A shareholder's attendance at a meeting constitutes a waiver by such
shareholder of (1) objection to lack of notice or defective notice of the
meeting, unless the shareholder at the beginning of the meeting objects to
holding the meeting or transacting business at the meeting, and (b) objection
to consideration of a particular matter at the meeting that is not within the
purpose or purposes described in the notice of the meeting, unless the
shareholder objects to considering the matter before it is voted upon.

     Section 2.6 RECORD DATE. For the purpose of determining shareholders
entitled to notice of or to vote at any meeting of


                                      -2-
<PAGE>   3
shareholders or any adjournment thereof, or in order to make a determination of
shareholders for any other proper purpose, the Board of Directors may fix in
advance a date as the record date for one or more voting groups for any such
determination of shareholders, such record date in any case to be not more than
seventy (70) days immediately preceding the date of the meeting or the date on
which the particular action, requiring such determination of shareholders, is to
be taken.

     If no record date is fixed for the determination of shareholders entitled
to notice of or to vote at a meeting of shareholders, the close of business on
the day before the date on which notice of the meeting is first mailed to
shareholders shall be the record date for such determination of shareholders.

     A determination of shareholders entitled to notice of or to vote at a
shareholders' meeting is effective for any adjournment of the meeting unless the
Board of Directors fixes a new record date for the adjourned meeting, which it
must do if the meeting is adjourned to a date more than 120 days after the date
fixed for the original meeting.

     Section 2.7 SHAREHOLDERS' LIST. Not later than two (2) business days after
the date that notice of a meeting of shareholders is first given, the Secretary
or other officer or person having charge of the stock transfer books of the
Corporation shall prepare an alphabetical list of the shareholders entitled to
notice of such meeting, with the address of and number of shares held by each,
arranged by voting group (and by class or series of shares within each voting
group), which list shall be kept on file at the principal office of the
Corporation (or such other place in the city where the meeting is to be held as
may be identified in the notice of the meeting) for the period commencing two
(2) business days after notice of the meeting is first given and continuing
through such meeting, and which list shall be available for inspection by any
shareholder, or his or her agent or attorney, upon his or her demand, at any
time during regular business hours. This list shall also be produced and kept
open at the time and place of the meeting and shall be subject to inspection by
any shareholder, or his or her agent or attorney, during the whole time of the
meeting and any adjournment thereof.

     Section 2.8 QUORUM. The holders of shares entitled to a majority of votes
entitled to be cast by a voting group (as described in Section 2.10), present
in person or represented by proxy, shall constitute a quorum of such voting
group at all meetings of shareholders for purposes of acting on any matter for
which action by such voting group is required. If there is no quorum at the
opening of a meeting of shareholders, such meeting may be adjourned from time to
time by the vote of a majority of the shares voting on the motion to adjourn;
and, at any adjourned meeting at which a quorum is present, any business may be



                                      -3-
<PAGE>   4
transacted which might have been transacted at the original meeting.

     Once a share is represented for any purpose at a meeting, it is deemed
present for quorum purposes for the remainder of the meeting and for any
adjournment thereof unless a new record date is or must be set for that
adjourned meeting.

     Section 2.9 ORGANIZATION. Each meeting of shareholders shall be presided
over by the Chief Executive Officer, or, in the absence or at the request of
the Chief Executive Officer, by such other officer as the Chief Executive
Officer or the Board of Directors may designate, or in their absence and in the
absence of such designation, by any person selected to preside by plurality
vote of the shares represented and entitled to vote at the meeting, with each
share having the same number of votes to which it would be entitled on any
other matter on which all shares represented and entitled to vote at the
meeting would be entitled to vote. The Secretary, or in the absence or at the
request of the Secretary, any person designated by the person presiding at the
meeting, shall act as secretary of the meeting.

     Section 2.10 VOTING OF SHARES. Except as otherwise provided in the
Articles of Incorporation of the Corporation, each outstanding share,
regardless of class, having the right to vote on a matter or matters submitted
to a vote at a meeting of shareholders shall be entitled to one vote on each
such matter. A shareholder may vote in person or by proxy.

     Except in the election of directors (as provided for in Section 3.4), if a
quorum of a voting group exists, action on a matter by such voting group is
approved by such voting group if the votes cast within such voting group
favoring the action exceed the votes cast within such voting group opposing the
action, unless a greater number of affirmative votes is required by law or the
Articles of Incorporation or a Bylaw adopted by the shareholders. If the
Articles of Incorporation, a Bylaw adopted by the shareholders or applicable
law provides for voting on a matter by two or more voting groups, action is
taken on that matter only when approved by each of those voting groups counted
separately; provided, that action may be taken by one voting group on a matter
even though no action is taken at the same time by another voting group
entitled to vote on the matter.

     Voting on all matters including the election of directors shall be by
voice vote or by a show of hands unless, as to any matter, the holders of
shares entitled to at least twenty-five percent (25%) of the votes of shares
represented at the meeting and entitled to vote on that matter shall demand,
prior to the voting on such matter, a ballot vote on such matter.

     As used in these Bylaws, the term "voting group" means all


                                      -4-
<PAGE>   5
shares of one or more classes or series that, under the Articles of
Incorporation or applicable law, are entitled to vote and be counted together
collectively on a matter at a meeting of shareholders. All shares entitled by
the Articles of Incorporation or applicable law to vote generally on the matter
are for that purpose a single voting group. So long as the Corporation shall
have only one class of shares outstanding and the voting rights of all shares
of such class are identical, then all such outstanding shares shall constitute
a single voting group and the sole voting group, except to the extent that
applicable law or the Articles of Incorporation requires that any of such
shares be treated as a separate voting group.

     Section 2.11 ACTION WITHOUT MEETING. Any action required or permitted to
be taken at a meeting of the shareholders may be taken without a meeting if one
or more written consents, describing the action so taken, shall be signed by
all of the persons who would be entitled to vote upon such action at a meeting,
whether before or after the action so taken, and shall be delivered to the
Corporation to be included in the corporate minute book or be filed with the
corporate record. Such consent has the same effect as a meeting vote and may be
described as such in any document. In the case of any action proposed to be so
taken by written consent that, if to be taken at a meeting, would require that
notice to be given to nonvoting shareholders, the Corporation shall give such
nonvoting shareholders written notice of the proposed action at least ten (10)
days before the action is taken, which notice shall contain or be accompanied
by the same material that, under applicable law, would have been required to be
sent to nonvoting shareholders in a notice of such a meeting.

     Section 2.12 INFORMAL ACTION BY SHAREHOLDERS. Any action which may be
taken at a meeting of the shareholders may be taken without a meeting if a
consent in writing, describing forth the action so taken, shall be signed by
all of the persons who would be entitled to vote upon such action at a meeting,
and filed with the Secretary of the Corporation to be kept in the corporate
minute book.

                                  ARTICLE III

                                   DIRECTORS

     Section 3.1 GENERAL POWERS. All corporate powers of the Corporation shall
be exercised by or under the authority of, and the business affairs of the
Corporation shall be managed under the direction of, the Board of Directors.

     Section 3.2 NUMBER, TERM AND QUALIFICATIONS. The number of directors of
this Corporation shall consist of such number, not less than three (3) nor more
than seven (7), as shall be determined


                                      -5-


<PAGE>   6
from time to time by resolution of the shareholders or the Board of Directors.
No such resolution reducing the number of directors below the number of
directors then in office shall of itself have the effect of removing any
director prior to the expiration of such director's term of office. Any
positions on the Board of Directors created by an increase in the number of
directors pursuant to such a resolution and not filled by the shareholders
shall be treated as vacancies to be filled by and in the discretion of the
Board of Directors. The number of directors fixed pursuant to such a resolution
shall be deemed to be the number of directors prescribed by these Bylaws.

     The terms of initial directors and the term of any director elected to
fill a vacancy shall expire at the next shareholders' meeting at which
directors are elected. Otherwise, the term of each director shall be the period
from the effective date of his or her election to the next annual meeting of
shareholders. Notwithstanding the stated terms of directors, a director shall
continue to serve after expiration of his or her stated term until his or her
successor is elected and qualifies or there is a decrease in the number of
directors eliminating his or her position, and a director shall cease to serve
as such and his or her position shall be deemed vacant upon his or her death,
resignation, removal of disqualification.

     Directors need not be residents of the State of North Carolina or
shareholders of the Corporation.

     Section 3.3 ELECTION OF DIRECTORS. Except as provided in Section 3.6,
directors other than the initial directors shall be elected at the annual
meeting of shareholders.

     Section 3.4 VOTING FOR DIRECTORS. Directors shall be elected by a
plurality of the votes cast by the shares entitled to vote in the election of
directors at a meeting at which a quorum is present. Except as provided in the
Articles of Incorporation or required by applicable law, shareholders have no
right to cumulate their votes for directors.

     Section 3.5 REMOVAL. Except as otherwise provided in the Articles of
Incorporation or by applicable law, a director may be removed from office with
or without cause by a vote of shareholders of the voting group entitled to
elect such directors, provided a quorum exists and the number of votes cast in
favor of such removal exceeds the number of votes cast against such removal. A
director may not be removed by the shareholders at a meeting unless the notice
of the meeting states that a purpose of the meeting is removal of such
director. If any directors are so removed, new directors may be elected at the
same meeting.

     Section 3.6 VACANCIES. A vacancy occurring in the Board of Directors,
including positions not filled by the shareholders or


                                      -6-
<PAGE>   7
those resulting from an increase in the number of directors, may be filled by a
majority of the remaining directors, though less than a quorum, or by the sole
remaining director. The shareholders may elect a director at any time to fill
any vacancy not filled by the directors.

     Section 3.7 COMPENSATION. The Board of Directors, in its discretion, may
compensate directors for their services as such and may provide for the payment
of all expenses incurred by the directors in attending regular and special
meetings of the Board or of any Committee or in the performance of their other
duties as directors. Nothing herein contained, however, shall be construed to
preclude any director from serving the Corporation in any other capacity and
receiving compensation therefor.

     Section 3.8 COMMITTEES. The Board of Directors, by resolution adopted by a
majority of the number of directors then in office, may designate and appoint
from among its members one or more Committees, each consisting of two or more
directors, who shall serve as members of such Committee at the pleasure of the
Board of Directors. Each such Committee, to the extent provided in such
resolution, shall have and may exercise all of the authority of the Board of
Directors in the management of the Corporation, except that no such Committee
shall have authority to: (a) authorize dividends or other distributions not
permitted by applicable law to be authorized by a Committee; (b) approve or
propose to shareholders action that applicable law requires to be approved by
shareholders; (c) fill vacancies on the Board of Directors or on any Committee;
(d) amend the Articles of Incorporation; (e) adopt, amend or repeal bylaws; (f)
approve a plan of merger not requiring shareholder approval; (g) authorize or
approve reacquisition of shares, except according to a formula or method
prescribed by the Board of Directors; (h) authorize or approve reacquisition of
shares, except according to a formula or method prescribed by the Board of
Directors; (h) authorize or approve the issuance or sale or contract for sale
of shares, or determine the designation and relative rights, preferences and
limitations of a class or series of shares (except that the Board of Directors
may authorize a Committee or a senior executive officer to do so within limits
specifically prescribed by the Board of Directors); or (i) amend or repeal any
resolution of the Board of Directors that by its terms provides that it is not
so amendable or repealable. Nothing herein shall preclude the Board of
Directors from establishing and appointing any committee, whether of directors
or otherwise, not having or exercising the authority of the Board of Directors.

                                   ARTICLE IV

                             MEETINGS OF DIRECTORS

same place as, the annual meeting or substitute annual meeting of shareholders.
In addition, the Board of Directors may provide, by resolution, the time and
place, either within or without the State of North Carolina, for the holding of
additional regular meetings.

     Section 4.2 SPECIAL MEETINGS. Special meetings of the Board of Directors
may be called by or at the request of the Chairman of the Board (if there shall
be a person holding such office), the Chief Executive Officer or any two
directors. Such meetings may be held within or without the State of North
Carolina.

     Section 4.3 NOTICE OF MEETINGS.  Regular meetings of the Board of
Directors may be held without notice.

     The person or persons calling a special meeting of the Board of Directors
shall, at least two days before the meeting, give notice thereof by any usual
means of communication. Such notice need not specify the purpose for which the
meeting is called.

     A director's attendance at or participation in a meeting shall constitute
a waiver by such director of notice of such meeting, unless the director at the
beginning of the meeting (or promptly upon his or her arrival) objects to
holding the meeting or to the transaction of business at the meeting and does
not thereafter vote for or assent to action taken at the meeting.

     Section 4.4 QUORUM. A majority of the number of directors fixed or
prescribed by these Bylaws shall be required for, and shall constitute, a
quorum for the transaction of business at any meeting of the Board of Directors.

     Section 4.5 MANNER OF ACTING. Except as otherwise provided in these Bylaws
or required by applicable law, the affirmative vote of a majority of the
directors present at a meeting of the Board of Directors shall be the act of
the Board of Directors, if a quorum is present when the vote is taken.

     Section 4.6 ORGANIZATION. Each meeting of the Board of Directors shall be
presided over by the Chairman of the Board (if there shall be a person holding
such office), or, in the absence or at the request of the Chairman of the
Board, by the Chief Executive Officer, and in their absence or at their
request, by any person selected to preside by vote of a majority of the
directors present. The Secretary, or in the absence or at the request of the
Secretary, any person designated by the person presiding at the meeting, shall
act as secretary of the meeting.

     Section 4.7 ACTION WITHOUT MEETING. Action required or permitted to be
taken by the Board of Directors or a Committee at a meeting may be taken
without a meeting if one or more written consents describing the action taken
are signed by each of the directors or members of the Committee, as the case
may be, whether before or after the action so taken, and filed with corporate


                                      -8-
<PAGE>   9

records or the minutes of the proceedings of the Board or Committee. Action so
taken is effective when the last consent specifies a different effective date.
Such consent has the effect of a meeting vote and may be described as such in
any document.

     Section 4.8  PARTICIPATION BY CONFERENCE TELEPHONE. Any one or more
directors or members of a Committee may participate in a meeting of the Board
of Directors or Committee by means of a conference telephone or similar
communications device that allows all persons participating in the meeting to
simultaneously hear each other during the meeting, and such participation in a
meeting shall be deemed presence in person at such meeting.

such Vice Presidents, Assistant Secretaries, Assistant Treasurers and other

more officers is required. The title of any officer may include any additional
designation descriptive of such officer's duties as the Board of Directors may
prescribe.

     Section 5.2  APPOINTMENT AND TERM. The officers of the Corporation shall
be appointed from time to time by the Board of Directors; provided, that the
Board of Directors may authorize a duly appointed officer to appoint one or
more other officers or assistant officers, other than appointment of the Chief

Operating Officer. Each officer shall serve as such at the pleasure of the
Board of Directors.

     Section 5.3  REMOVAL. Any officer may be removed by the Board of Directors

and authority of the Chief Executive Officer and shall also, when present,
preside over meetings of the Board of Directors. If there is a Chairman of the
Board but such Chairman of the Board is not also designated as the Chief

<PAGE>   11
the President shall be the Chief Operating Officer and shall have all of the
duties and authority of that office. If the President shall be the Chief
Executive Officer and no other officer shall have been designated by the Board
of Directors as the Chief Operating Officer, then the President shall also have
all of the duties and authority of the Chief Operating Officer. The President
shall also have such other duties and authority as may be prescribed from time
to time by the Board of Directors.

     Section 5.9  VICE PRESIDENT.  The Vice President, and if there be more

                         CONTRACTS, LOANS AND DEPOSITS

     Section 6.1 CONTRACTS. The Board of Directors may authorize any officer or
officers, agent or agents, to enter into any contract or execute and deliver
any document or instrument on behalf of the Corporation, and such authority may
be general or confined to specific instances. Any resolution of the Board of
Directors authorizing the execution of documents by the proper officers of the
Corporation or by the officers generally and not specifying particular officers
shall be deemed to authorize such execution by the Chief Executive Officer, the

                               SHARE CERTIFICATES

     Section 7.1 CERTIFICATES FOR SHARES. Unless the Board of Directors
authorizes the issue of some or all of the shares of any or all classes or
series without certificates, certificates representing shares of the
Corporation shall be issued, in such form as the Board of Directors shall
determine, to every shareholder for the fully paid shares owned by him. These
certificates shall be signed by the Chief Executive Officer, the Chief
Operating Officer, the Chairman of the Board, the Assistant Secretary, the
Treasurer or an Assistant Treasurer, either manually or in facsimile (provided
that certificates bearing facsimile signatures of both officers shall be
manually countersigned by a registrar, transfer agent or other authenticating
agent). They shall be consecutively numbered or otherwise identified; and the
name and address of the persons to whom they are issued, with the number of
shares and date of issue, shall be entered on the stock transfer books of the
Corporation.

     Section 7.2 TRANSFER OF SHARES. Transfer of shares represented by
certificates shall be made on the stock transfer books of the Corporation only
upon the surrender of the certificates for the shares sought to be transferred
by the record holder thereof or by his duly authorized agent, transferee or
legal representative, or as otherwise provided by applicable law. All
certificates surrendered for transfer shall be canceled before new certificates
for the transferred shares shall be issued.

     Section 7.3 LOST CERTIFICATES. The Board of Directors may authorize the
issuance of a new share certificate in place of a certificate claimed to have
been lost, destroyed or wrongfully taken, upon receipt of an affidavit of such
fact from the person claiming the loss or destruction. When authorizing such
issuance of a new certificate, the Board may require the claimant to give the
Corporation a bond in such sum and with such sureties as it may direct to
indemnify the Corporation against loss from any claim with respect to the
certificate claimed to have been lost, destroyed or wrongfully taken; or the
Board may, by resolution reciting that the circumstances justify such action,
authorize the issuance of the new certificate without requiring such a bond
with respect to a certificate claimed to have been lost or destroyed. Any such
authorization by the Board of Directors may be general or confined to specific
instances. Nothing herein shall require the Board of Directors to authorize the
issuance of any such replacement certificate under any circumstances in which
the Corporation is not required to issue such certificate, this provision being
permissible and not mandatory.

declare, and the Corporation may pay, dividends on its outstanding shares in
the manner and upon the terms and conditions provided by law and the Articles
of Incorporation of the Corporation. The Board of Directors may fix in advance

two concentric circles between or within which are name of the Corporation, the
state of incorporation, the year of incorporation and the word "SEAL." The seal

officer to represent the corporate seal of the Corporation, in which case such
seal shall be as effective as the corporate seal in the form herein prescribed.

     Section 9.3 NOTICE AND WAIVER OF NOTICE. Except as otherwise provided in
the Articles of Incorporation or these Bylaws, any notice permitted or required
to be given pursuant to these Bylaws may be given in any manner permitted by

the Corporation's current record of shareholders.

     Whenever any notice is required to be given to any shareholder or director
under the provisions of the North Carolina Business Corporation Act under the
provisions of the Articles of Incorporation or Bylaws of the corporation, a
waiver thereof in writing signed by the person or persons entitled to such
notice and included in the minutes or filed with the corporate records, whether
done before or after the time stated in the notice, shall be equivalent to the
giving of such notice.

     Section 9.4 FISCAL YEAR. The fiscal year of the Corporation shall be fixed

     Section 9.5 INDEMNIFICATION. Any person who at any time serves or has

including reasonable attorneys' fees, actually and necessarily incurred by him
or her in connection with any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative, whether
formal or informal, and whether or not brought by or on behalf of the
Corporation, arising out of his or her status as such director, or his or her
status as an officer, employee or agent of the Corporation, or his or her

trustee, employee or agent of any other corporation, partnership, joint
venture, trust or other enterprise or as a trustee or administrator under an
employee benefit plan, or his or her activities in any of the foregoing
capacities, and (b) any liability incurred by him, including without
limitation, satisfaction of any judgment, money decree, fine (including any
excise tax assessed with respect to an employee benefit plan), penalty or
settlement, for which he or she may have become liable in connection with any
such action, suit or proceeding.

     The Board of Directors of the Corporation shall take all such action as
may be necessary and appropriate to authorize the Corporation to pay the
indemnification required by this Bylaw, including without limitation, to the
extent necessary, (a) making a good faith evaluation of the manner in which the
claimant for indemnity acted and of the reasonable amount of indemnity due him
or her and (b) giving notice to and obtaining approval by the shareholders of
the Corporation.

     Expenses incurred by a director in defending an action, suit or proceeding
may be paid by the Corporation in advance of the final disposition of such
action, suit or proceeding upon receipt of an undertaking by or on behalf of
the director to pay such amount unless it shall ultimately be determined that
he or she is entitled to be indemnified by the Corporation against such


                                      -17-
<PAGE>   18

expenses.

     Any person who at any time after the adoption of this Bylaw serves or has
served as a director of the Corporation shall be deemed to be doing or to have
done so in reliance upon, and as consideration for, the right of indemnification
provided herein, and any modification or repeal of these provisions for
indemnification shall be prospective only and shall not affect any rights or
obligations existing at the time of such modification or repeal. Such right
shall inure to the benefit of the legal representatives of any such person,
shall not be exclusive of any other rights to which such person may be entitled
apart from the provisions of this Bylaw, and shall not be limited by the
provisions for indemnification in Section 55-8-51 through 55-8-56 or the North
Carolina Business Corporation Act or any successor statutory provisions. Any
person who is entitled to indemnification by the Corporation hereunder shall
also be entitled to reimbursement of reasonable costs, expenses and attorneys'
fees incurred in obtaining such indemnification.

therefor that the Corporation may, but need not, establish pursuant to
applicable law. All personal pronouns used in these Bylaws shall include
persons of any gender. All terms used herein and not specifically defined
herein but defined in the North Carolina Business Corporation Act shall have

the context otherwise requires.

Articles of Incorporation or by applicable law, these Bylaws may be amended or
repealed and new bylaws may be adopted by action of the Board of Directors or
the shareholders.

the first day of the last calendar month of the term hereof Tenant shall pay
to Landlord as rent for the period from said first day of said last calendar
month to and including the last day of the term hereof that proportion of the
monthly rent hereunder which the number of days between said first day of said
last calendar month and the last day of the term hereof bears to THIRTY (30).

     C. Late Charge. Notwithstanding any other provision of this Lease, if
Tenant is in default in the payment of rental as set forth in this Paragraph 4
when due, or any part thereof, Tenant agrees to pay Landlord, in addition to
the delinquent rental due, a late charge for each rental payment in default
TEN (10) DAYS. Said late charge shall equal TEN PERCENT (10%) of each rental
payment so in default.

     D. Additional Rent: Beginning with the commencement date of the term of
this Lease, Tenant shall pay to Landlord or to Landlord's designated agent in
addition to the Basic Rent and as Additional Rent the following:

     a) All Taxes relating to the Premises as set forth in Paragraph 9, and
     b) All insurance premiums relating to the Premises, as set forth in
Paragraph 12, and
     c) All charges, costs and expenses, which Tenant is required to pay
hereunder, together with all interest and penalties, costs and expenses
including reasonable attorneys' fees and legal expenses, that may accrue thereto
in the event of Tenant's failure to pay such amounts, and all damages,
reasonable costs and expenses which Landlord may incur by reason of default of
Tenant or failure on Tenant's part to comply with the terms of this Lease. In
the event of nonpayment by Tenant of Additional Rent, Landlord shall have all

agent (1) within FIVE (5) DAYS after presentation of invoice from Landlord or
Landlord's agent setting forth such Additional Rent and/or (ii) at the option of

monthly expenditure for such Additional Rent items,


                                      -2-
<PAGE>   3
which estimated amount shall be reconciled at the end of each calendar year as
compared to Landlord's actual expenditure for said Additional Rent Items, with
Tenant paying to Landlord, upon demand, any amount of actual expenses expended
by Landlord in excess of said estimate amount, or Landlord refunding to Tenant
(providing Tenant is not in default in the performance of any of the terms,
covenants and conditions of this Lease) any amount of estimated payments made
by Tenant in excess of Landlord's actual expenditures for said Additional Rent
Items.

     The respective obligations of Landlord and Tenant under this paragraph
shall survive the expiration or other termination of the term of this Lease,
and if the term hereof shall expire or shall otherwise terminate on a day other
than the last day of a calendar year, the actual Additional Rent incurred for
the calendar year in which the term hereof expires or otherwise terminates
shall be determined and settled on the basis of the statement of Additional
Rent for such calendar year and shall be prorated in the proportion which the
number of days in such calendar year preceding such expiration or termination
bears to 365.

     E.  PLACE OF PAYMENT OF RENT AND ADDITIONAL RENT.  A Basic Rent hereunder
and all payments hereunder for Additional Rent shall be paid to Landlord at the
office of Landlord at:

              SCP-I, 2100 BRYANT STREET, PALO ALTO, CA 94301-3906
          TELEPHONE: (650) 329-9182          FACSIMILE: (650) 329-8410

or such other person or to such other place as Landlord may from time to time

     F.  SECURITY DEPOSIT.  CONCURRENTLY WITH TENANT'S EXECUTION OF THIS LEASE,
TENANT SHALL DEPOSIT WITH LANDLORD THE SUM OF TWENTY-SIX THOUSAND FIVE HUNDRED
AND 00/100 DOLLARS ($26,500.00) IN ADDITION TO THE FIRST MONTH'S RENT AS STATED
IN PARAGRAPH 4(a), ABOVE. ON FEBRUARY 1, 1999, TENANT SHALL DEPOSIT
WITH LANDLORD THE SUM OF TWENTY-SIX THOUSAND FIVE HUNDRED AND 00/100 DOLLARS
($26,500.00) IN ADDITION TO THE FEBRUARY 1, 2000 RENT AS STATED IN PARAGRAPH
4(a), ABOVE FOR A TOTAL SECURITY DEPOSIT OF FIFTY-THREE THOUSAND AND 00/100
DOLLARS ($53,000.00). Said sum shall be held by Landlord as a Security Deposit
for the faithful performance by Tenant of all the terms, covenants and
conditions of this Lease to be kept and performed by Tenant during the term
hereof. If Tenant defaults with respect to any provision of this Lease,
including, but not limited to, the provisions relating to the payment of rent
and any of the monetary sums due herewith, Landlord may (but shall not be
required to) use, apply or retain all or any part of this Security Deposit for
the payment of any other amount which Landlord may spend by reason of Tenant's
default or to compensate Landlord for any other loss or damage which Landlord
may suffer by reason of Tenant's default. If any portion of said Deposit is so
used or applied, Tenant shall, within TEN (10) DAYS after written demand
therefor, deposit cash with Landlord in the amount sufficient to restore the
Security Deposit to it's original amount. Tenant's failure to do so shall be a
material breach of this Lease. Landlord shall not be required to keep this
Security Deposit from its general funds, and Tenant shall not be entitled to
interest on such Deposit. If Tenant fully and faithfully performs every
provision of this Lease to be performed by it, the Security Deposit or any
balance thereof shall be returned to Tenant (or at Landlord's option, to the
last assignee of Tenant's interest hereunder) at the expiration of the Lease
term and after Tenant has vacated the Premises. In the event of termination of
Landlord's interest in this Lease, Landlord shall transfer said Deposit to
Landlord's successor in interest whereupon Tenant agrees to release Landlord
from liability for the return of such Deposit or the accounting therefor.

     5.   ACCEPTANCE AND SURRENDER OF THE PREMISES:  By entry hereunder, Tenant
accepts the Premises as being in good and sanitary order, condition and repair
and accepts the building and improvements included in the Premises in their
present condition and without representation or warranty by Landlord as to the
condition of such building or as to the use or occupancy which may be made
thereof. Any exceptions to the foregoing must be by written agreement executed
by Landlord and Tenant. Tenant agrees on the last day of the Lease term, or on
the sooner termination of this Lease, to surrender the Premises promptly and
peaceably to Landlord in good condition and repair (damage by Acts of God, fire,
normal wear and tear excepted), with all interior walls painted, or cleaned so
that they appear freshly painted, and repaired and replaced, if damaged; all
floors cleaned and waxed; all carpets cleaned and shampooed; all broken, marred
or nonconforming ceiling tiles replaced; all windows washed; the air
conditioning and heating systems serviced by a reputable and licensed service
firm and in good operating condition and repair; the plumbing and electrical
systems and lighting in good order and repair, including replacement of any
burned out or broken light bulbs or ballasts; the lawn and shrubs in good
condition including the replacement of any dead or damaged plantings; the
sidewalk, driveways and parking areas in good order, condition and repair;
together with all alterations, additions and improvements which may have been
made in, to or on the Premises (except moveable trade fixtures installed at the
expense of Tenant) except that Tenant shall ascertain from Landlord within
THIRTY (30) DAYS before the end of the term of this Lease whether Landlord
desires to have the Premises or any part or parts thereof restored to their
condition and configuration as when the Premises were delivered to Tenant and if
Landlord shall so desire, then Tenant shall restore said Premises or such part
or parts thereof before the end of this Lease at Tenant's sole cost and expense.
Tenant, on or before the end of the term or sooner termination of this Lease,
shall remove all of the Tenant's personal property and trade fixtures from the
Premises, and all property not so removed on or before the end of the term or
sooner termination of this Lease shall be deemed abandoned by Tenant and title
to same shall thereupon pass to Landlord without compensation to Tenant.
Landlord may, upon termination of this Lease, remove all moveable furniture and
equipment so abandoned by Tenant, at Tenant's sole cost, and repair any damage
caused by such removal at Tenant's sole cost. If the Premises are not
surrendered at the end of the term or sooner termination of this Lease, Tenant
shall indemnify Landlord against loss or liability resulting from the delay by
Tenant in so surrendering the Premises including, without limitation, any claims
made by any succeeding tenant founded, on such delay. Nothing contained herein
shall be construed as an extension of the term hereof or as a consent of
Landlord to any holding over by Tenant. The voluntary or other surrender of this
Lease or the Premises by Tenant or a mutual cancellation of this Lease shall not
work as a merger and, at the option of Landlord, shall either terminate all or
any existing subleases or subtenancies or operate as an assignment to Landlord
of all or any such subleases or subtenancies.

6.   ALTERATIONS AND ADDITIONS:  Tenant shall not make, or suffer to be made,
any alteration or addition to the Premises, or any part thereof, without the
written consent of Landlord first had and obtained by Tenant (such consent not
to be unreasonably withheld), but at the cost of Tenant, and any addition to, or
alteration of, the Premises, except moveable furniture and trade fixtures, shall
at once become a part of the Premises and belong to Landlord. Landlord reserves
the right to approve all contractors and mechanics proposed by Tenant to make
such alterations and additions. Tenant shall retain title to all moveable
furniture and trade fixtures placed in the Premises. All heating, lighting,
electrical, air conditioning, partitioning, drapery, carpeting, and floor
installations made by Tenant, together with all property that has become an
integral part of the Premises, shall not be deemed trade fixtures. Tenant agrees
that it will not proceed to make such alterations or additions, without having

                                      -3-
<PAGE>   4

obtained consent from Landlord to do so, and until FIVE (5) DAYS from the
receipt of such consent, in order that Landlord may post appropriate notices to
avoid any liability to contractors or material suppliers for payment for
Tenant's Improvements. Tenant will at all times permit such notices to be posted
and to remain posted until the completion of work. Tenant shall, if required by
Landlord, secure at Tenant's own cost and expense, a completion and lien
indemnity bond, satisfactory to Landlord, for such work. Tenant further
covenants and agrees that any mechanic's lien filed against the Premises for
work claimed to have been done for, or materials claimed to have been furnished
to Tenant, will be discharged by Tenant, by bond or otherwise, within TEN (10)
DAYS after the filing thereof, at the cost and expense of Tenant. Any exceptions
to the foregoing must be made in writing and executed by both Landlord and
Tenant.

7. TENANT MAINTENANCE: Tenant shall, at its sole cost and expense, keep and
maintain the Premises (including appurtenances) and every part thereof in a high
standard of maintenance and repair, or replacement, and in good and sanitary
condition. Tenant's maintenance and repair responsibilities herein referred to
include, but are not limited to, janitorization, all windows (interior and
exterior), window frames, plate glass and glazing (destroyed by accident or act
of third parties), truck doors, plumbing systems (such as water and drain lines,
sinks, toilets, faucets, drains showers and water fountains), electrical systems
(such as panels, conduits, outlets, lighting fixtures, lamps, bulbs, tubes and
ballasts), heating and air conditioning systems (such as compressors, fans, air
handlers, ducts, mixing boxes, thermostats, time clocks, boilers, heaters,
supply and return grills), structural elements and exterior surfaces of the
building, store fronts, roofs, downspouts, all interior improvements within the
premises including but not limited to wall coverings, window coverings, carpet,
floor coverings, partitioning, ceilings, doors (both interior and exterior),
including closing mechanisms, latches, locks, skylights (if any), automatic fire
extinguishing systems, and elevators and all other interior improvements of any
nature whatsoever, and all exterior improvements including but not limited to
landscaping, sidewalks, driveways, parking lots including striping and sealing,
sprinkler systems, lighting, ponds, fountains, waterways, and drains. Tenant
agrees to provide carpet shields under all rolling chairs or to otherwise be
responsible for wear and tear of the carpet caused by such rolling chairs if
such wear and tear exceeds that caused by normal foot traffic in surrounding
areas. Areas of excessive wear and tear shall be replaced at Tenant's sole
expense upon Lease termination. Tenant hereby waives all rights under, and
benefits of, Subsection 1 of Section 1932 and Section 1941 and 1942 of the
California Civil Code and under any similar law, statute or ordinance now or
hereafter in effect. In the event any of the above maintenance responsibilities
apply to any other tenant(s) of Landlord where there is common usage with other
tenant(s), such maintenance responsibilities and charges shall be allocated to
the leased Premises by square footage or other equitable basis as calculated and
determined by Landlord.

8. UTILITIES: Tenant shall pay promptly, as the same become due, all charges for
water, gas, electricity, telephone, telex and other electronic communication
service, sewer service, waste pick-up and any other utilities, materials or
services furnished directly to or used by Tenant on or about the Premises during
the term of this Lease, including, without limitation, any temporary or
permanent utility surcharge or other exactions whether or not hereinafter
imposed. In the event the above charges may apply to any other tenant(s) of
Landlord where there is common usage with other tenant(s), such charges shall be
allocated to the leased Premises by square footage or other equitable basis as
calculated and determined by Landlord.

     Landlord shall not be liable for and Tenant shall not be entitled to any
abatement or reduction of rent by reason of any interruption or failure of
utility services to the Premises when such interruption or failure is caused by
accident, breakage, repair, strikes, lockouts, or other labor disturbances or
labor disputes of any nature, or by any other cause, similar or dissimilar,
beyond the reasonable control of Landlord.

     Tenant shall indemnify Landlord for any payment for any utilities, which
Landlord pays on Tenant's behalf.

9. TAXES:

     A. As Additional Rent and in accordance with Paragraph 4D of this Lease,
Tenant shall pay to Landlord, or if Landlord so directs, directly to the Tax
Collector, all Real Property Taxes relating to the Premises. In the event the
Premises leased hereunder consist of only a portion of the entire tax parcel,
Tenant shall pay to Landlord Tenant's proportionate share of such real estate
taxes allocated to the leased Premises by square footage or other reasonable
basis as is calculated and determined by Landlord. If the tax billing pertains
100% to the leased Premises, and Landlord chooses to have Tenant pay said real
estate taxes directly to the Tax Collector, then in such event it shall be the
responsibility of Tenant to obtain the tax and assessment bills and pay, prior
to delinquency, the applicable real property taxes and assessments pertaining to
the leased Premises, and failure to receive a bill for taxes and/or assessments
shall not provide a basis for cancellation of or non-responsibility for payment
of penalties for nonpayment or late payment by Tenant. The term "Real Property
Taxes", as used herein, shall mean (i) all taxes, assessments, levies and other
charges of any kind or nature whatsoever, general and special, foreseen and
unforeseen (including all installments of principal and interest required to pay
any general or special assessments for public improvements and any increases
resulting from reassessments caused by any change in ownership of the Premises)
now or hereafter imposed by any governmental or quasi-governmental authority or
special district having the direct or indirect power to tax or levy assessments,
which are levied against, or with respect to the value, occupancy or use of, all
or any portion of the Premises (as now constructed or as may at any time
hereafter be constructed, altered, or otherwise changed) or Landlord's interest
therein; any improvements located within the Premises (regardless of ownership);
the fixtures, equipment and other property of Landlord, real or personal, that
are an integral part of and located in the Premises; or parking areas, public
utilities, or energy within the Premises; (ii) all charges, levies or fees
imposed by reason of environmental regulation or other governmental control of
the Premises; and (iii) all costs and fees (including reasonable attorneys'
fees) incurred by Landlord in reasonably contesting any Real Property Tax and in
negotiating with public authorities as to any Real Property Tax. If at any time
during the term of this Lease the taxation or assessment of the Premises
prevailing as of the commencement date of this Lease shall be altered so that in
lieu of or in addition to any Real Property Tax described above there shall be
levied, assessed or imposed (whether by reason of a change in the method of
taxation or assessment, creation of a new tax or charge, or any other cause) an
alternate or additional tax or charge (i) on the value, use or occupancy of the
Premises or Landlord's interest therein or (ii) on or measured by the gross
receipts, income or rentals from the Premises, on Landlord's business of leasing
the Premises, or computed in any manner with respect to the operation of the
Premises, then any such tax or charge, however designated, shall be included
within the meaning of the term "Real Property Taxes" for purposes of this Lease.
If any Real Property Tax is based upon property or rents unrelated to the
Premises, then only that part of such Real Property tax that is fairly allocable
to the Premises shall be included within the meaning of the term "Real Property
Taxes". Notwithstanding the foregoing, the term "Real Property Taxes" shall not
include estate, inheritance, gift or franchise taxes of Landlord or the federal
or state net income tax imposed on Landlord's income from all sources.

                                      -4-

<PAGE>   5

     B. TAXES ON TENANT'S PROPERTY. Tenant shall be liable for and shall pay
TEN (10) DAYS before delinquency, taxes levied against any personal property or
trade fixtures placed by Tenant in or about the Premises. If any such taxes on
Tenant's personal property or trade fixtures are levied against Landlord or
Landlord's property or if the assessed value of the Premises is increased by the
inclusion therein of a value placed upon such personal property or trade
fixtures of Tenant and if Landlord, after written notice to Tenant, pays the
taxes based on such increased assessment, which Landlord shall have the right to
do regardless of the validity thereof, but only under proper protest if
requested by Tenant, Tenant shall upon demand, as the case may be, repay to
Landlord the taxes so levied against Landlord, or the proportion of such taxes
resulting from such increase in the assessment; provided that in any such event
Tenant shall have the right, in the name of Landlord and with Landlord's full
cooperation, to bring suit in any court of competent jurisdiction to recover the
amount of such taxes so paid under protest, and any amount so recovered shall
belong to Tenant.

10.  LIABILITY INSURANCE: Tenant, at Tenant's expense, agrees to keep in force
during the term of this Lease a policy of comprehensive general liability
insurance for bodily injury and property damage occurring in, or about the
Premises, including parking and landscaped areas, in the amount of TWO MILLION
DOLLARS ($2,000,000.00) combined single limit. Such insurance shall be primary
and noncontributory as respects any insurance carried by Landlord. The policy
or policies effecting such insurance shall name Landlord as additional
insureds, and shall insure any liability of Landlord, contingent or otherwise,
as respects acts or omissions of Tenant, its agents, employees or invitees or
otherwise by any conduct or transactions of any of said persons in or about or
concerning the Premises, including any failure of Tenant to observe or perform
any of its obligations hereunder; shall be issued by an insurance company
admitted to transact business in the State of California; and shall provide
that the insurance effected thereby shall not be canceled, except upon THIRTY
(30) DAYS' prior written notice to Landlord. A copy of said policy should be
delivered to Landlord. If, during the term of this Lease, in the considered
opinion of Landlord's Lender, insurance advisor, or counsel, the amount of
insurance described in this Paragraph 10 is not adequate, Tenant agrees to
increase said coverage to such reasonable amount as Landlord's Lender,
insurance advisor, or counsel shall deem adequate.

11. TENANT'S PERSONAL PROPERTY INSURANCE AND WORKERS' COMPENSATION INSURANCE:
Tenant shall maintain a policy or policies of fire and property damage
insurance in "all risk" form with a sprinkler leakage endorsement insuring the
personal property, inventory, trade fixtures, and leasehold improvements within
the leased Premises for the full replacement value thereof. The proceeds from
any of such policies shall be used for the repair or replacement of such items
so insured.

     Tenant shall also maintain a policy or policies of workers' compensation
insurance and any other employee benefit insurance sufficient to comply with
all laws.

12. PROPERTY INSURANCE: Landlord shall purchase and keep in force, and as
Additional Rent and in accordance with Paragraph 4D of this Lease, Tenant shall
pay to Landlord Tenant's proportionate share (allocated to the leased Premises
by square footage or other equitable basis as calculated and determined by
Landlord) of the cost of, policy or policies of insurance covering loss or
damage to the Premises (excluding routine maintenance and repairs and
incidental damage or destruction caused by accidents or vandalism for which
Tenant is responsible under Paragraph 7) in the amount of the full replacement
value thereof, providing protection against those perils included within the
classification of "all risks" insurance and flood and/or earthquake insurance,
if available, plus a policy of rental income insurance in the amount of ONE
HUNDRED PERCENT (100%) PERCENT of TWELVE (12) MONTHS' Basic Rent, plus sums
paid as Additional Rent. If such insurance cost is increased due to Tenant's
use of the Premises, Tenant agrees to pay Landlord the full cost of such
increase. Tenant shall have no interest in nor any right to the proceeds of any
insurance procured by Landlord for the Premises.

     Landlord and Tenant do each hereby respectively release the other, to the
extent of insurance coverage of the releasing party, from any liability for
loss or damage caused by fire or any of the extended coverage casualties
included in the releasing party's insurance policies, irrespective of the cause
of such fire or casualty; provided, however, that if the insurance policy of
either releasing party prohibits such waiver, then this waiver shall not take
effect until consent to such waiver is obtained. If such waiver is so
prohibited, the insured party affected shall promptly notify the other party
thereof.

13. INDEMNIFICATION: Landlord shall not  be liable to Tenant and Tenant hereby
waives all claims against Landlord for any injury to or death of any person or
damage to or destruction of property in or about the Premises by or from any
cause whatsoever, including, without limitation, gas, fire, oil, electricity or
leakage of any character from the roof, walls, basement or other portion of the
Premises but excluding, however, the negligence of Landlord, its agents,
servants, employees, invitees, or contractors of which negligence Landlord has
knowledge and reasonable time to correct. Except as to injury to persons or
damage to property the principal cause of which is the negligence of Landlord,
Tenant shall hold Landlord harmless from and defend Landlord against any and
all expenses, including reasonable attorneys' fees, in connection therewith,
arising out of any injury to or death of any person or damage to or destruction
of property occurring in, on or about the Premises, or any part thereof, from
any cause whatsoever.

14. COMPLIANCE: Tenant at its sole cost and expense, shall promptly comply with
all laws, statutes, ordinances and governmental rules, regulations or
requirements now or hereafter in effect; with the requirements of any board of
fire underwriters or other similar body now or hereafter constituted; and with
any direction or occupancy certificate issued pursuant to law by any public
office; provided, however, that no such failure shall be deemed a breach of the
provisions if Tenant, immediately upon notification, commences to remedy or
rectify said failure. The judgment of any court of competent jurisdiction or
the admission of Tenant in any action against Tenant, whether by Landlord be a
party thereto or not, that Tenant has violated any such law, statute, ordinance
or governmental rule, regulation, requirement, direction or provision, shall be
conclusive of that fact as between Landlord and Tenant. Tenant shall, at its
own cost and expense, comply with any and all requirements pertaining to said
Premises, of any insurance organization or company, necessary for the
maintenance of reasonable fire and public liability insurance covering
requirements pertaining to said Premises, of any insurance organization or
company, necessary for the maintenance of reasonable fire and public liability
insurance covering the Premises.

15. LIENS: Tenant shall keep the Premises free from any liens arising out of
work performed, materials furnished or obligation incurred by Tenant. In the
event that Tenant shall not, within TEN (10) DAYS following the imposition of
such lien, cause the same to be released of record, Landlord shall have, in
addition to all other remedies


                                      -5-

<PAGE>   6
provided herein and by law, the right, but no obligation, to cause the same to
be released by such means as it shall deem proper, including payment of the
claim giving rise to such lien. All sums paid by Landlord for such purpose, and
all expenses incurred by it in connection therewith, shall be payable to
Landlord by Tenant on demand with interest at the prime rate of interest as
quoted by the Bank of America.

16. ASSIGNMENT AND SUBLETTING: Tenant shall not assign, transfer, or hypothecate
the leasehold estate under this Lease, or any interest therein, and shall not
sublet the Premises, or any part thereof, or any right or privilege appurtenant
thereto, or suffer any other person or entity to occupy or use the Premises, or
any portion thereof, without, in each case, the prior written consent of
Landlord which consent will not be unreasonably withheld. As a condition for
granting this consent to any assignment, transfer, or subletting, Landlord may
require that Tenant agrees to pay Landlord, as additional rent, all rents or
additional consideration received by Tenant from its assignees, transferees, or
subtenants in excess of the rent payable by Tenant to Landlord hereunder. Tenant
shall, by NINETY (90) DAYS' written notice, advise Landlord of its intent to
assign or transfer Tenant's interest in the Lease or sublet the Premises or any
portion thereof for any part of the term hereof. Within THIRTY (30) DAYS after
receipt of said written notice, Landlord may, in its sole discretion, elect to
terminate this Lease as to the portion of the Premises described in Tenant's
notice on the date specified in Tenant's notice by giving written notice of such
election to terminate. If no such notice to terminate is given to Tenant within
said THIRTY (30) DAY period, Tenant may proceed to locate an acceptable
sublessee, assignee, or other transferee for presentment to Landlord for
Landlord's approval, all in accordance with the terms, covenants, and conditions
of this Paragraph 16. If Tenant intents to sublet the entire Premises and
Landlord elects to terminate this Lease, this Lease shall be terminated on the
date specified in Tenant's notice. If, however, this Lease shall terminate
pursuant to the foregoing with respect to less than all the Premises, the rent,
as defined and reserved hereinabove shall be adjusted on a pro rata basis to the
number of square feet retained by Tenant, and this Lease as so amended shall
continue in full force and effect. In the event Tenant is allowed to assign,
transfer or sublet the whole or any part of the Premises, with the prior written
consent of Landlord, no assignee, transferee or subtenant shall assign or
transfer this Lease, either in whole or in part, or sublet the whole or any part
of the Premises, without also having obtained the prior written consent of
Landlord. A consent of Landlord to one assignment, transfer, hypothecation,
subletting, occupation or use by any other person shall not release Tenant from
any of Tenant's obligations hereunder and be deemed to be a transfer,
hypothecation, subletting, occupation or use without such consent shall be void
and shall constitute a breach of this Lease by Tenant and shall, at the option
of Landlord exercised by written notice to Tenant, terminate this Lease. The
leasehold estate under this Lease shall not, or shall any interest therein, be
assignable for any purpose by operation of law without the written consent of
Landlord. As a condition to its consent, Landlord may require Tenant to pay all
expenses in connection with the assignment, and Landlord may require Tenant's
assignee or transferee (or other assignees or transferees) to assume in writing
all of the obligations under this Lease and for Tenant to remain liable to
Landlord under this Lease.

17. SUBORDINATION AND MORTGAGES: In the event Landlord's title or leasehold
interest is now or hereafter encumbered by a deed of trust, upon the interest of
Landlord in the land and buildings in which the demised Premises are located, to
secure a loan from a lender (hereinafter referred to as "Lender") to Landlord,
Tenant shall, at the request of Landlord or Lender, execute in writing an
agreement subordinating its rights under this Lease to the lien of such deed of
trust, or, if so requested, agreeing that the lien of Lender's deed of trust
shall be or remain subject and subordinate to the rights of Tenant under this
Lease. Tenant hereby irrevocably appoints Landlord the attorney in fact of
Tenant to execute, deliver and record any such instrument or instruments for and
in the name and on behalf of Tenant. Notwithstanding any such subordination,
Tenant's possession under this Lease shall not be disturbed if Tenant is not in
default and so long as Tenant shall pay all rent and observe and perform all of
the provisions set forth in this Lease.

18. ENTRY BY LANDLORD: Landlord reserves, and shall at all reasonable times
have, the right to enter the Premises to inspect them; to perform any services
to be provided by Landlord hereunder; to make repairs or provide any services to
a contiguous tenant(s); to submit the Premises to prospective purchasers,
mortgagors or tenants; to post notices of non-responsibility; and to alter,
improve or repair the Premises or other parts of the building, all without
abatement of rent, and may erect scaffolding and other necessary structures in
or through the Premises where reasonably required by the character of the work
to be performed; provided, however, that the business of Tenant shall be
interfered with to the least extent that is reasonably practical. Any entry to
the Premises by Landlord for the purposes provided for herein shall not be
construed or deeded to be a forcible or unlawful entry into or a detainer of the
Premises or an eviction, actual or constructive, of Tenant from the Premises or
any portion thereof.

19. BANKRUPTCY AND DEFAULT: The commencement of a bankruptcy action or
liquidation action or reorganization action or insolvency action or an
assignment of or by Tenant for the benefit of creditors, or any similar action
undertaken by Tenant, or the insolvency of Tenant, shall, at Landlord's option,
constitute a breach of this Lease by Tenant. If the trustee or receiver
appointed to serve during a bankruptcy, liquidation, reorganization, insolvency
or similar action elects to reject Tenant's unexpired Lease, the trustee or
receiver shall notify Landlord in writing of its election within THIRTY (30)
DAYS after an order for relief in a liquidation action or within THIRTY (30)
DAYS after the commencement of any action.

          Within thirty (30) DAYS after court approval of the assumption of this
Lease, the trustee or receiver shall cure (or provide adequate assurance to the
reasonable satisfaction of Landlord that the trustee or receiver shall cure) any
and all previous defaults under the unexpired Lease and shall compensate
Landlord for all actual pecuniary loss and shall provide adequate assurance of
future performance under said Lease to the reasonable satisfaction of Landlord.
Adequate assurance of future performance, as used herein, includes, but shall
not be limited to: (i) assurance of source and payment of rent, and other
consideration due under this Lease; (ii) assurance that the assumption or
assignment of this Lease will not breach substantially any provision, such as
radius, location, use, or exclusivity provision, in any agreement relating to
the above described Premises.

          Nothing contained in this section shall affect the existing right of
Landlord to refuse to accept an assignment upon commencement of or in connection
with a bankruptcy, liquidation, reorganization or insolvency action or an
assignment of Tenant for the benefit of creditors or other similar act. Nothing
contained in this Lease shall be construed as giving or granting or creating an
equity in the demised Premises to Tenant. In no event shall the leasehold estate
under this Lease, or any interest therein, be assigned by voluntary or
involuntary bankruptcy proceeding without the prior written consent of Landlord.
In no event shall this Lease or any rights or privileges hereunder be an asset
of Tenant under any bankruptcy, insolvency or reorganization proceedings.

          The failure to perform or honor any covenant, condition or
representation made under this Lease shall constitute a default hereunder by
Tenant upon expiration of the appropriate grace period hereinafter provided.


                                      -6-
<PAGE>   7
Tenant shall have a period of FIVE (5) DAYS from the date of written notice from
Landlord within which to cure any default in the payment of rental or adjustment
thereto. Tenant shall have a period of TEN (10) DAYS from the date of written
notice from Landlord within which to cure any other default under this Lease.
Upon an uncured default of this Lease by Tenant, Landlord shall have the
following rights and remedies in addition to any other rights or remedies
available to Landlord at law or in equity:

     (a)  The rights and remedies provided for by California Civil Code Section
1951.2, including but not limited to, recovery of the net worth at the time of
award of the amount by which the unpaid rent for the balance of the term after
the time of award exceeds the amount of rental loss for the same period that
Tenant proves could be reasonably avoided, as computed pursuant to subsection
(b) of said section 1951.2. Any proof by Tenant under subparagraphs (2) and (3)
of Section 1951.2 of the California Civil Code of the amount of rental loss that
could be reasonably avoided shall be made in the following manner: Landlord and
Tenant shall each select a licensed real estate broker in the business of
renting property of the same type and use as the Premises and in the same
geographic vicinity. Such two real estate brokers shall select a third licensed
real estate broker, and the three licensed real estate brokers so selected shall
determine the amount of the rental loss that could be reasonably avoided from
the balance of the term of this Lease after the time of award. The decision of
the majority of said licensed real estate brokers shall be final and binding
upon the parties hereto.

     (b)  The rights and remedies provided by California Civil Code Section
1951.4 which allows Landlord to continue the Lease in effect and to enforce all
of its rights and remedies under this Lease, including the right to recover rent
as it becomes due, for so long as Landlord does not terminate Tenant's right to
possession. Acts of maintenance or preservation, efforts to re-let the Premises,
or the appointment of a receiver upon Landlord's initiative to protect its
interest under this Lease shall not constitute a termination of Tenant's right
to possession.

     (c)  The right to terminate this Lease by giving notice to Tenant in
accordance with applicable law.

     (d)  The right and power, as attorney-in-fact for Tenant, to enter the
Premises and remove therefrom all persons and property, to store such property
in a public warehouse or elsewhere at the cost of and for the account of Tenant,
and to sell such property and apply such proceeds therefrom pursuant to
applicable California law. Landlord, as attorney-in-fact for Tenant, may from
time to time sublet the Premises or any part thereof for such term or terms
(which may extend beyond the term of this Lease) and at such rent and such other
terms as Landlord in its reasonable sole discretion may deem advisable, with the
right to make alterations and repairs to the Premises. Upon each subletting, (i)
Tenant shall be immediately liable to pay Landlord, in addition to indebtedness
other than the rent due hereunder, the reasonable cost of such subletting,
including, but not limited to, reasonable attorneys' fees, and any real estate
commissions actually paid, and the cost of such reasonable alterations and
repairs incurred by Landlord and the amount, if any, by which the rent hereunder
for the period of such subletting (to the extent such period does not exceed the
term hereof) exceeds the amount to be paid as rent for the Premises for such
period or (ii) at the option of Landlord, rents received from such subletting
shall be applied in payment of future rent as the same becomes due hereunder. If
Tenant has been credited with any rent to be received by such subletting under
option (i) and such rent shall not be promptly paid to Landlord by the
subtenant(s), or if such rentals received from such subletting under option (ii)
during any month be less that to be paid during that month by Tenant hereunder,
Tenant shall pay any such deficiency to Landlord. Such deficiency shall be
calculated and paid monthly. For all purposes set forth in this subparagraph
(d), Landlord is hereby irrevocably appointed attorney-in-fact for Tenant, with
power of substitution. No taking possession of the Premises by Landlord, as
attorney-in-fact for Tenant, shall be construed as an election on its part to
terminate this Lease unless a written notice of such intention be given to
Tenant. Notwithstanding any such subletting without termination, Landlord may at
any time hereafter elect to terminate this Lease for such previous breach.

     (e)  The right to have a receiver appointed for Tenant upon application by
Landlord, to take possession of the Premises and to apply any rental collected
from the Premises and to exercise all other rights and remedies granted by
Landlord as attorney-in-fact for Tenant pursuant to subparagraph (d), above.

20.  ABANDONMENT: Tenant shall not vacate or abandon the Premises at any time
during the term of this Lease; and if Tenant shall abandon, vacate or surrender
the Premises, or be dispossessed by the process of law, or otherwise, any
personal property belonging to Tenant and left on the Premises shall be deemed
to be abandoned, at the option of Landlord, except such property as may be
mortgaged to Landlord.

21.  DESTRUCTION: In the event the Premises are destroyed in whole or in part
from any cause, except for routine maintenance and repairs and incidental damage
and destruction caused from vandalism and accidents for which Tenant is
responsible under Paragraph 7, Landlord may, at its option:

     (a)  Rebuild or restore the Premises to their condition prior to the
damage or destruction, or

     (b)  Terminate this Lease.

     If Landlord does not give Tenant notice in writing within THIRTY (30) DAYS
from the destruction of the Premises of its election to either rebuild and
restore them, or to terminate this Lease, Landlord shall be deemed to have
elected to rebuild or restore them, in which event Landlord agrees, at its
expense, promptly to rebuild or restore the Premises to their condition prior to
the damage or destruction. Tenant shall be entitled to a reduction in rent while
such repair is being made in the proportion that the area of the Premises
rendered untenantable by such damage bears to the total area of the Premises. If
Landlord does not complete the rebuilding or restoration within ONE HUNDRED
EIGHTY (180) DAYS following the date of destruction (such period of time to be
extended for delays caused by the fault or neglect of Tenant or because of Acts
of God, acts of public agencies, labor disputes, strikes, fires, freight
embargoes, rainy or stormy weather, inability to obtain materials, supplies or
fuels, acts of contractors or subcontractors, or delay of the contractors or
subcontractors due to such causes or other contingencies beyond the control of
Landlord), then Tenant shall have the right to terminate this Lease by giving
FIFTEEN (15) DAYS' prior written notice to Landlord. Notwithstanding anything
herein to the contrary, Landlord's obligation to rebuild or restore shall be
limited to the building and interior improvements constructed by Landlord as
they existed as of the commencement date of the Lease and shall not include
restoration of Tenant's trade fixture, equipment, merchandise, or any
improvements, alterations or additions made by Tenant to the Premises, which
Tenant shall forthwith replace or fully repair at Tenant's sole cost and expense
provided this Lease is not cancelled according to the provisions above.

     Unless this Lease is terminated pursuant to the foregoing provisions, this
Lease shall remain in full force and effect. Tenant hereby expressly waives the
provisions of Section 1932, Subdivision 2, in Section 1933, Subdivision 4 of the
California Civil Code.

     In the event that the building in which the Premises are situated is
damaged or destroyed to the extent of not less than 33-1/3% of the replacement
cost thereof, Landlord may elect to terminate this Lease, whether the Premises
be injured or not. In the event Tenant causes the destruction of the Premises,
Tenant shall pay the deductible portion of Landlord's insurance proceeds.

                                                                         Maude 2



22. EMINENT DOMAIN: If all or any part of the Premises shall be taken by any
public or quasi-public authority under the power of eminent domain or
conveyance in lieu thereof, this Lease shall terminate as to any portion of the
Premises so taken or conveyed on the date when title vests in the condemnor,
and Landlord shall be entitled to any and all payment, income, rent, award, or
any interest therein whatsoever which may be paid or made in connection with
such taking or conveyance, and Tenant shall have no claim against Landlord or
otherwise for the value of any unexpired term of this Lease. Notwithstanding
the foregoing paragraph, any compensation specifically awarded Tenant for loss
of business, Tenant's personal property, moving cost or loss of goodwill, shall
be and remain the property of Tenant.

      If any action or proceeding is commenced for such taking of the Premises
or any part thereof, then Landlord shall have the right to terminate this Lease
by giving Tenant written notice thereof within SIXTY (60) DAYS of the date or
receipt of said written advice, or commencement of said action or proceeding,
or taking conveyance, which termination shall take place as of the first to
occur of the last day of the calendar month next following the month in which
such notice is given or the date on which title to the Premises shall vest in
the condemnor.

      In the event of such a partial taking or conveyance of the Premises, if
the portion of the Premises taken or conveyed is so substantial that the Tenant
can no longer reasonably conduct its business, Tenant shall have the privilege
of terminating this Lease within SIXTY (60) DAYS from the date of such taking
or conveyance, upon written notice to Landlord of its intention to do so, and
upon giving of such notice this Lease shall terminate on the last day of the
calendar month next following the month in which such notice is given, upon
payment by Tenant of the rent from the date of such taking or conveyance to the
date of termination.

      If a portion of the Premises is taken by condemnation or conveyance in
lieu thereof and neither Landlord nor Tenant shall terminate this Lease as
provided herein, this Lease shall continue in full force and effect as to the
part of the Premises not so taken or conveyed, and the rent herein shall be
apportioned as of the date of such taking or conveyance so that thereafter the
rent to be paid by Tenant shall be in the ratio that the area of the portion of
the Premises not so taken or conveyed bears to the total area of the Premises
prior to such taking.

23. SALE OR CONVEYANCE BY LANDLORD: In the event of a sale or conveyance of the
Premises or any interest therein, by any owner of the reversion then
constituting Landlord, the transferor shall thereby be released from any
further liability upon any of the terms, covenants or conditions (express or
implied) herein contained in favor of Tenant, and in such event, insofar as
such transfer is concerned, Tenant agrees to look solely to the responsibility
of the successor in interest of such transferor in and to the Premises and this
Lease. This Lease shall not be affected by any such sale or conveyance, and
Tenant agrees to attorn the successor in interest of such transferor.

24. ATTORNMENT TO LENDER OR THIRD PARTY: In the event the interest of Landlord
in the land and buildings in which the leased Premises are located (whether
such interest of Landlord is a fee title interest or a leasehold interest) is
encumbered by deed of trust, and such interest is acquired by the lender or any
third party through judicial foreclosure or by exercise of a power of sale at
private trustee's foreclosure sale, Tenant hereby agrees to attorn to the
purchaser at any such foreclosure sale and to recognize such purchaser as the
Landlord under this Lease. In the event the lien of the deed of trust securing
the loan from a Lender to Landlord is prior and paramount to the Lease, this
Lease shall nonetheless continue in full force and effect for the remainder of
the unexpired term hereof, at the same rental hereinreserved and upon all the
other terms, conditions and covenants herein contained.

25. HOLDING OVER: Any holding over by Tenant after expiration or other
termination of this Lease with the written consent of Landlord delivered to
Tenant shall not constitute a renewal or extension of the Lease or give Tenant
any rights in or to the leased premises except as expressly provided in this
Lease. Any holding over after the expiration or other termination of the term
of this Lease, with consent of Landlord, shall be construed to be a tenancy
from month-to-month, on the same terms and conditions herein specified insofar
as applicable except that the monthly rent shall be increased to an amount
equal to ONE HUNDRED FIFTY PERCENT (150%) of the monthly rent required during
the last month of the Lease term.

26. CERTIFICATE OF ESTOPPEL: Tenant shall at any time upon not less than TEN
(10) DAYS' prior written notice to Landlord execute, acknowledge and deliver to
Landlord a statement in writing (i) certifying that this Lease is unmodified
and in full force and effect (or, if modified, stating the nature of such
modification and certifying that this Lease, as so modified, is in full force
and effect) and the date to which the rent and other charges are paid in
advance, if any, and (ii) acknowledging that there are not, to Tenant's
knowledge, any uncured defaults on the part of Landlord hereunder, or
specifying such defaults, if any, are claimed. Any such statement may be
conclusively relied upon by any prospective purchaser or encumbrancer of the
Premises. Tenant's failure to deliver such statement within such time shall be
conclusive upon Tenant that this Lease is in full force and effect, without
modification except as may be represented by Landlord, that there are no
uncured defaults in Landlord's performance, and that not more than one month's
rent has been paid in advance.

27. CONSTRUCTION CHANGES: It is understood that the description of the Premises
and the location of ductwork, plumbing and other facilities therein are subject
to such minor changes as Landlord and Landlord's architect determines to be
desirable in the course of construction of the Premises, and no such changes
shall affect this Lease or entitle Tenant to any reduction of rent hereunder or
result in any liability of Landlord to Tenant. Landlord does not guarantee the
accuracy of any drawings supplied to Tenant and verification of the accuracy of
such drawings rests with Tenant.

28. RIGHT OF LANDLORD TO PERFORM: All terms, covenants and conditions of this
Lease to be performed or observed by Tenant shall be performed or observed by
Tenant and Tenant's sole cost and expense and without any reduction of rent. If
Tenant shall fail to pay any sum of money, or other rent, required to be paid
by it hereunder or shall fail to perform any other term or covenant hereunder
on its part to be performed, and such failure shall continue for FIVE (5) DAYS
after written notice thereof by Landlord, Landlord, without waiving or
releasing Tenant from any obligation of Tenant hereunder, may, but shall not be
obliged to, make any such payment or perform any such other term or covenant on
Tenant's part to be performed. All sums so paid by Landlord and all necessary
costs of such performance by Landlord together with interest thereon at the
rate of the prime rate of interest per annum as quoted by the Bank of America
from the date of such payment on performance by Landlord, shall be paid (and
Tenant covenants to make such payment) to Landlord on demand by Landlord, and
Landlord shall have

                                                 575 N. Pastoria Ave., Sunnyvale
                                                                         Maude 2


(in addition to any other right or remedy of Landlord) the same rights and
remedies in the event of nonpayment by Tenant as in the case of failure by
Tenant in the payment of rent hereunder.

29. ATTORNEYS' FEES:
      A. In the event that Landlord should bring suit for the possession of the
Premises, for the recovery of any sum due under this Lease, or because of the
breach of any provision of this Lease, or for any other relief against Tenant
hereunder, then all costs and expenses, including reasonable attorneys' fees,
incurred by the prevailing party therein shall be paid by the other party,
which obligation on the part of the other party shall be deemed to have accrued
on the date of the commencement of such action and shall be enforceable whether
or not the action is prosecuted to judgment.

      B. Should Landlord be named as a defendant in any suit brought against
Tenant in connection with or arising out of Tenant's occupancy hereunder,
Tenant shall pay to Landlord its costs and expenses incurred in such suit,
including reasonable attorneys' fees.

30. WAIVER: The waiver by either party of the other party's failure to perform
or observe any term, covenant or condition herein contained to be performed or
observed by such waiving party shall not be deemed to be a waiver of such term,
covenant or condition or of any subsequent failure of the party failing to
perform or observe the same or any other such term, covenant or condition
therein contained, and no custom or practice which may develop between the
parties hereto during the term hereof shall be deemed a waiver of, or in any
way affect, the right of either party to insist upon performance and observance
by the other party in strict accordance with the terms hereof.

31. NOTICES: All notices, demands, requests, advices or designations which may
be or are required to be given by either party to the other hereunder shall be
in writing. All notices, demands, requests, advices or designations by
Landlord to Tenant shall be sufficiently given, made or delivered if personally
served on Tenant by leaving the same at the Premises or if sent by United
States certified or registered mail, postage prepaid, addressed to Tenant at
the Premises. All notices, demands, requests, advices or designations by Tenant
to Landlord shall be sent by United States certified or registered mail,
postage prepaid, addressed to Landlord at its offices at:

              SCP-I, 2100 BRYANT STREET, PALO ALTO, CA 94301-3906
             TELEPHONE: (650) 329-9182    FACSIMILE: (650) 329-8410

Each notice, request, demand, advice or designation referred to in this
paragraph shall be deemed received on the date of the personal service or
mailing thereof in the manner herein provided, as the case may be.

32. EXAMINATION OF LEASE: Submission of the instrument for examination or
signature by Tenant does not constitute a reservation of or option for a lease,
and this instrument is not effective as a lease or otherwise until its
execution and delivery by both Landlord and Tenant.

33. DEFAULT BY LANDLORD: Landlord shall not be in default unless Landlord fails
to perform obligations required of Landlord within a reasonable time, but in no
event earlier than THIRTY (30) DAYS after written notice by Tenant to Landlord
and to the holder of any first mortgage or deed of trust covering the Premises
whose name and address shall have heretofore been furnished to Tenant in
writing, specifying wherein Landlord has failed to perform such obligations;
provided, however, that if the nature of Landlord's obligations is such that
more than THIRTY (30) DAYS are required for performance, then Landlord shall
not be in default if Landlord commences performance within such THIRTY (30) DAY
period and thereafter diligently prosecutes the same to completion.

34. CORPORATE AUTHORITY: If Tenant is a corporation (or a partnership), each
individual executing this Lease on behalf of said corporation (or partnership)
represents and warrants that he is duly authorized to execute and deliver this
Lease on behalf of said corporation (or partnership) in accordance with the
by-laws of said corporation (or partnership in accordance with the partnership
agreement) and that this Lease is binding upon said corporation (or
partnership) in accordance with its terms. If Tenant is a corporation, Tenant
shall, within THIRTY (30) DAYS after execution of this Lease, deliver to
Landlord a certified copy of the resolution of the Board of Directors of said
corporation authorizing or ratifying the execution of this Lease.

35. LIMITATION OF LIABILITY: In consideration of the benefits accruing
hereunder, Tenant and all successors and assigns covenant and agree that, in
the event of any actual or alleged failure, breach or default hereunder by
Landlord:

      (a) the sole and exclusive remedy shall be against Landlord and
Landlord's assets;
      (b) no partner of Landlord shall be sued or named as a party in any suit
or action (except as may be necessary to secure jurisdiction of the
partnership);
      (c) no service of process shall be made against any partner of Landlord
(except as may be necessary to secure jurisdiction of the partnership);
      (d) no partner of Landlord shall be required to answer or otherwise plead
to any service of process;
      (e) no judgment will be taken against any partner of Landlord;
      (f) any judgment taken against any partner of Landlord may be vacated and
set aside at any time without hearing;
      (g) no writ of execution will ever be levied against the assets of any
partner of Landlord;
      (h) these covenants and agreements are enforceable by both Landlord and
also by any partner of Landlord.

      Tenant agrees that each of the foregoing covenants and agreements shall
be applicable to any covenant or agreement either expressly contained in this
Lease or imposed by statute or at common law.

36. SIGNS: No sign, placard, picture, advertisement, name or notice shall be
inscribed, displayed or printed or affixed on or to any part of the outside of
the Premises or any exterior windows of the Premises without the written
consent of Landlord first had and obtained and Landlord shall have the right to
remove any such sign, placard, picture, advertisement, name or notice without
notice to and at the expense of Tenant. If Tenant is allowed to

<PAGE>   10
                                                 575 N. Pastoria Ave., Sunnyvale
                                                                         Maude 2

print or affix or in any way place a sign in, on, or about the Premises, upon
expiration or sooner termination of this Lease, Tenant at Tenant's sole cost
and expense shall both remove such sign and repair all damage in such a manner
as to restore all aspects of the appearance of the Premises to the condition
prior to the placement of said sign.

     All approved signs or lettering on outside doors shall be printed,
painted, affixed or inscribed at the expense of Tenant by a person approved of
by Landlord.

     Tenant shall not place anything or allow anything to be placed near the
glass of any window, door partition or wall, which may appear unsightly from
outside the Premises.

37. HAZARDOUS MATERIALS/USE OF PREMISES:

     A. As used herein, the term "Hazardous Material" shall mean any substance
or material which has been determined by any state, federal or local
governmental authority to be capable of posing a risk of injury to health,
safety or property, including all of those materials and substances designated
as hazardous or toxic by the city in which the Premises are located, the U.S.
Environmental Protection Agency, the Consumer Product Safety Commission, the
Food and Drug Administration, the California Water Resources Control Board, the
Regional Water Quality Control Board, San Francisco Bay Region, the California
Air Resources Board, CAL/OSHA Standards Board, California Department of Food and
Agriculture, the California Department of Health Services, and any federal
agencies that have overlapping jurisdiction with such California agencies, or
any other governmental agency now or hereafter authorized to regulate materials
and substances in the environment. Without limiting the generality of the
foregoing, the term "Hazardous Material" shall include all of those materials
and substances defined as "Toxic Materials" in Sections 66680 through 66685 of
Title 22 of the California Administrative Code, Division 4, Chapter 30, as the
same shall be amended from time to time, or any other materials requiring
remediation under federal, state or local statutes, ordinances, regulations or
policies.

     B. Tenant agrees not to introduce any Hazardous Material in, on or
adjacent to the Premises without complying with all applicable federal, state
and local laws, rules, regulations, policies and authorities relating to the
storage, use or disposal, and cleanup of Hazardous Materials, including, but
not limited to, the obtaining of proper permits.

     C. Tenant shall immediately notify Landlord of any inquiry, test,
investigation, or enforcement proceeding by or against Landlord or the Premises
concerning a Hazardous Material. Tenant acknowledges that Landlord, as the
owner of the Premises, shall have the right, at its election, in its own name
or as a Tenant's agent, to negotiate, defend, approve, and appeal, at Tenant's
expense, any action taken or order issued with regard to a Hazardous Material
by an applicable governmental authority.

     D. If Tenant's storage, use or disposal of any Hazardous Material in, on
or adjacent to the Premises results in any contamination of the Premises, the
soil or surface or groundwater requiring remediation under federal, state or
local statutes, ordinances regulations or policies, Tenant agrees to cleanup
the contamination. Tenant further agrees to indemnify, defend and hold Landlord
harmless from and against any claims, suits, causes of action, costs, fees,
including attorneys' fees and costs, arising out of or in connection with any
cleanup work, inquiry or enforcement proceeding in connection therewith, and
any Hazardous Materials currently or hereafter used, stored or disposed of by
Tenant or its agents, employees, contractors or invitees on or about the
Premises.

     E. Notwithstanding any other right or entry granted to Landlord under this
Lease, Landlord shall have the right to enter the Premises or to have
consultants enter the Premises throughout the term of this Lease for the
purpose of determining: (1) whether the Premises are in conformity with
federal, state and local statutes, regulations, ordinances and policies
including those pertaining to the environmental condition of the Premises, (2)
whether Tenant has complied with this Paragraph (37) and the Lease, and (3) the
corrective measures, if any, required of Tenant to ensure the safe use, storage
and disposal of Hazardous Materials, or to remove Hazardous Materials in
accordance with applicable laws. Tenant agrees to provide access and reasonable
assistance for such inspections. Such inspections may include, but are not
limited to, entering the Premises or adjacent property with drill rigs or other
machinery for the purpose of obtaining laboratory samples. Landlord shall not
be limited in the number of such inspections during the term of this Lease. If
such consultants determine that Tenant has contaminated the Premises with
Hazardous Materials used, stored or caused to be used or stored by Tenant,
Tenant shall reimburse Landlord for the cost of such inspections within TEN
(10) DAYS of receipt of a written statement thereof. Tenant shall, in a timely
manner, at its expense, remove such Hazardous Materials or otherwise comply
with the recommendations of such consultants to the reasonable satisfaction of
Landlord and any applicable governmental agencies. The right granted to
Landlord herein to inspect the Premises shall not create a duty on Landlord's
part to inspect the Premises, or liability of Landlord for Tenant's use,
storage or disposal of Hazardous Materials, it being understood that Tenant
shall be solely responsible for all liability in connection therewith.

     F. Tenant shall surrender the Premises to Landlord upon the expiration or
earlier termination of this Lease free of Hazardous Materials used, stored or
caused to be used or stored by Tenant on the Premises, and in a condition which

requirements as may be imposed by Landlord with respect to those Hazardous
Materials used, stored or caused to be used or stored by Tenant.

     H. Tenant agrees to provide Landlord with a Hazardous Material audit or
list as to any Hazardous Materials Tenant used, stored, disposed of or caused

within FIVE (5) DAYS of the written request by Landlord for said audit.

38. "ZERO-TOLERANCE" DRUG CLAUSE:

occupancy of the demised Premises, not to cause, permit or allow the use of any
controlled or illegal substances on the Premises, including, without implied
limitation, those substances defined by virtue of Health & Safety Code of the
State of California Section 11007.

     Tenant covenants and agrees that any such activity on more than one
occasion shall constitute a nuisance and Landlord will be entitled, but not
limited, to all remedies provided for under California Code of Civil Procedure,
Section 1164(4). Tenant acknowledges that such prohibited activity will, at the
sole discretion of Landlord, result in

                                6,000,000 SHARES

                        AMERICAN MULTIPLEXER CORPORATION

                       WARRANT TO PURCHASE COMMON SHARES

                                 MAY 14th 1999



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.

          THIS IS TO CERTIFY THAT, for value received, Edward S C Tan, President
and CEO of American Multiplexer Corporation, ("the holder") is entitled to
purchase from American Multiplexer Corporation (the "Company"), a corporation
organized under the laws of North Carolina, at any time or from time to time
during the period (the "Exercise Period") commencing on the date hereof (the
"Commencement Date") until 5:00 p.m., California Time, on May 14th, 2004 (the
"Expiration Date"), up to 6,000,000 fully paid and non-assessable common shares,
no par value, of the Company (the "Common Shares"), as now constituted, all per
share in accordance with the terms and provisions hereof. The number of Common
Shares to be received upon the exercise of this Warrant and the price to be paid
for each Common Share shall be adjusted from time to time as hereinafter set
forth. The Common Shares or other securities or property deliverable upon such
exercise, as adjusted from time to time, are hereinafter sometimes referred to
as "Warrant Shares" and the exercise price of a Common Share in effect at any
time and as adjusted from time to time is hereinafter sometimes referred to as
the "Exercise Price". Unless the context otherwise requires, the term "Warrant"
or "Warrants" as used herein includes this Warrant and any other Warrant or
Warrants which may be issued pursuant to the provisions of this Warrant, whether
upon transfer, assignment, partial exercise, divisions, combinations, exchange,
or otherwise, and the term- "Holder" includes any transferee or transferees or
assignee or assignees of the Holder named above, all of whom shall be subject to
the provisions of the Warrant, and, when used with reference to Warrant Shares,
means the holder or holders of such Warrant Shares.

     Subject to Paragraph 5 hereof, this Warrant is exercisable at a purchase
price of $1.00 per share (the "Exercise Price").

          The Common Shares issuable upon exercise of this Warrant have not been
registered with the Securities and Exchange Commission. This Warrant was
originally issued pursuant to and in satisfaction of all the work put in by
Edward Tan including bringing in funds for the company.

1. EXERCISE OF WARRANTS

     The purchase rights represented by this Warrant are exercisable from time
to time at the option of the Holder hereof; in whole or in part (but not as to
fractional Common Shares), during the Exercise Period until 5:00 p.m. California
time on the Expiration Date by presentation and surrender to Company at its
principal office, with the warrant exercise form attached hereto, duly executed
and
<PAGE>   2
accompanied by payment (either in cash or by certified or official bank check,
payable to the order of the Company) of the Exercise Price for the number of the
Warrant Shares specified in such form. In case of the purchase of fewer than all
of the Common Shares purchasable under this Warrant, the Company shall cancel
this Warrant upon the surrender thereof and shall execute and deliver a new
Warrant of like tenor, dated the date hereof; for the balance of the Common
Shares purchasable hereunder. Each person in whose name any certificate for
Common Shares is issued shall, for all purposes, be deemed to have become the
Holder of record of such shares on the date of exercise of this Warrant,
irrespective of the date of delivery of such certificate, except that if the
stock transfer books of the Company are closed on such exercise date, such
person shall be deemed to have become the Holder of record of such shares at the
close of business on the next succeeding date on which the stock transfer books
are open. The Company shall take all actions necessary to ensure that all Common
Shares issued upon the exercise of this Warrant are, when they are issued as
provided herein, duly and validly authorized and issued, fully paid and
non-assessable.

     2.   ISSUANCE OF STOCK CERTIFICATES

          The issuance of certificates for Common Shares upon the exercise of
this Warrant shall be made without charge to the Holder hereof and such
certificates shall be issued in the name of; or in such names as may be directed
by, the Holder hereof; provided, however, that the Company shall not be required
to pay any transfer tax that may be payable in respect of any transfer involved
in the issuance and delivery of any such certificate in a name other than that
of the Holder, and the Company shall not be required to issue or deliver such
certificates unless or until the person or person requesting the issuance
thereof shall have paid to the Company the amount of such transfer tax or shall
have established to the satisfaction of the Company that such transfer tax has
been paid or that no such tax is due.

     3.   RIGHTS OF HOLDER

          Nothing in this Warrant shall be construed as conferring upon the
Holder hereof any rights as shareholder of the Company. No provision of this
Warrant, in the absence of affirmative action by the Holder to purchase Common
Shares, and no mere enumeration herein of the rights or privileges of the
Holder, shall give rise to any liability of the holder for the Exercise Price or
as a shareholder of the Company, whether such liability is asserted by the
Company or by creditors thereof.
<PAGE>   3
     4.   RESTRICTIONS ON TRANSFERABILITY: REDEMPTION

          Any such assignment shall be effected by the Holder (i) executing the
form of assignment at the end hereof and (ii) surrendering this Warrant for
cancellation at the office or agency of the Company, accompanied by a
certificate (signed by the holder, or an officer of the Holder if the Holder is
a corporation), stating that each transferee is a permitted transferee under
this paragraph 4; whereupon the Company shall issue, in the name or names
specified by the Holder (including the Holder) a new Warrant or Warrants of
like tenor and representing in the aggregate rights to purchase the same number
of Common Shares as are purchasable hereunder.

     5.   ADJUSTMENT OF EXERCISE PRICE AND WARRANT SHARES PURCHASABLE

          (a) The Exercise Price at which Common Shares shall be purchasable,
as set forth in Section 1 hereof; shall be $1.00 per share, subject to
adjustment from time to time, if the Company shall declare a dividend payable
in Common Shares, subdivide or combine the outstanding Common Shares, the
Exercise Price shall be adjusted (to the nearest whole cent) to that price
determined by multiplying the Exercise Price in effect immediately prior to
such event by a fraction (i) the numerator of which shall be the number of
Common Shares outstanding immediately prior to such event and (ii) the
denominator of which shall be the number of Common Shares outstanding
immediately after such event. Appropriate readjustment of the Exercise Price
shall be made if any dividend referred to above shall be abandoned.

          (b) In the event of an adjustment of the Exercise Price, the number
of Common Shares (or reclassified stock) issuable upon exercise of this Warrant
after such adjustment shall be equal to the number determined by dividing (i)
an amount equal to the product of (1) the number of Common Shares issuable upon
exercise of this Warrant immediately prior to such adjustment, and (2) the
Exercise Price immediately prior to such adjustment; by (ii) the Exercise Price
immediately after such adjustment.

          (c) In the event of any reorganization or reclassification of the
outstanding Common Shares (other than a change in par value, or from par value
to no par value, or from no par value to par value, or as a result of a
subdivision or combination) or in the event of any consolidation of the Company
with, or merger of the Company with, another entity after which no securities
of the Company will be publicly held, or in the event of any sale, lease or
conveyance of all, or substantially all, of the property, assets, business and
goodwill of the Company as an entity, the Holder of this Warrant shall
thereupon or thereafter, at any time after the Commencement Date and prior to
the Expiration Date, have the right, but not the obligation, to exercise this
Warrant. Upon such exercise, the Holder shall have the right to purchase and/or
receive the kind and amount of stock and other securities, cash or other
property receivable upon such reorganization, reclassification, consolidation,
merger or sale by a holder of the number of Common Shares which the Holder of
this Warrant would have received had he exercised this Warrant immediately
prior to such reorganization, reclassification, consolidation, merger or sale,
at a price equal to the aggregate Exercise Price then in effect pertaining

<PAGE>   4
to this Warrant (the kind, amount and price of such stock and other securities
to be subject to adjustment as herein provided). After any such reorganization,
reclassification, consolidation, merger or sale which shall result in any cash
distribution in excess of the Exercise Price provided for by this Warrant, the
Holder of this Warrant may at his option exercise the same without making
payment of the Exercise Price and in such case the Company shall upon the
distribution to said Holder, consider that said Exercise Price has been paid in
full to it and in making settlement to said Holder, shall deduct from the
amount payable to such Holder an amount equal to such Exercise Price.

          (d)  In the event the Company shall, at any time after the
Commencement Date and prior to the Expiration Date and prior to the exercise
thereof dissolve, liquidate or wind up its affairs, the Holder of this Warrant
shall thereupon or thereafter at any time be entitled, but not obligated, to
exercise this Warrant, and upon the exercise thereof; to receive, in lieu of
the Common Shares of the Company which he would have been entitled to receive,
the same kind and amount of assets as would have been issued, distributed or
paid to him upon any such dissolution, liquidation or winding up with respect
to such Common Shares of the Company, had he been the holder of record of such
Common Shares receivable upon the exercise of this Warrant on the record date
for the determination of those entitled to receive any such liquidating
distribution. After any such dissolution, liquidation or winding up which shall
result in any cash distribution in excess of the Exercise Price provided for by
this Warrant, the Holder of this Warrant may at his option exercise the same
without making payment of the Exercise Price, and in such case the Company
shall upon the distribution to said Holder consider that said Exercise Price
has been paid in full to it and in making settlement to said Holder shall
deduct from the amount payable to such Holder an amount equal to such Exercise
Price.

          (e) Irrespective of any adjustments in the Exercise Price or the
number or kind of shares purchasable upon exercise of this Warrant, this
Warrant may continue to express the same price and number and kind of shares as
when originally issued.

          (f) The Company may retain a firm of independent public accountants
of recognized standing (who may be any such firm regularly employed by the
Company) to make any computation required under this Section, and a Certificate
signed by such firm shall be conclusive evidence of the correctness of any
computation made under this Paragraph.

          (g) Notwithstanding anything contained herein to the contrary, no
adjustment of the Exercise Price or the number of shares issuable upon exercise
of this Warrant shall be made for any action taken by the Company pursuant to
written agreements in existence on the original issue date of this Warrant.

     6.   OFFICER'S CERTIFICATE

          Whenever the Exercise Price shall be adjusted as required by the
provisions of Paragraphs, the Company shall forthwith file in the custody of
its Secretary or an Assistant Secretary at its principal office and, in the
event it shall have informed the Holder that an agent has been designated as an
agent for the exercise or transfer of this Warrant, with such warrant transfer
agent, an


<PAGE>   5
officer's certificate showing the adjusted Exercise Price determined as therein
provided, setting forth in reasonable detail the facts requiring such
adjustment, including a statement of the number of additional Common Shares, if
any, the consideration for such shares, determined as provided in Paragraph 5,
and such other facts as shall be necessary to show the officer's certificate
shall be made available at all reasonable times for inspection by the Holder of
this Warrant and the Company shall, forthwith after each such adjustment, mail
copy of such certificate to such Holder by certified mail, return receipt
requested.

     7.   NOTICES TO WARRANT HOLDER

          So long as this Warrant shall be outstanding, (i) if the Company
shall pay any dividend or make any distribution upon the Common Shares
otherwise than in cash and out of earned surplus, or (ii) if the Company shall
offer to the holders of Common Shares for subscription or purchase by them any
shares of any class or any other rights, or (iii) if there shall be any
reclassification of the capital stock of the Company, consolidation or merger
of the Company with or into another corporation, sale, lease or transfer of all
or substantially all of the property and assets of the Company, or voluntary or
involuntary dissolution, liquidation or winding up of the Company shall be
effected, then in any such event, the Company shall cause to be mailed by
certified mail to the Holder, at least thirty days prior to the date specified
in (x) or (y) below, as the case may be, a notice containing a brief
description of the proposed action and stating the date or expected date on
which (x) a record is to be taken for the purpose of such dividend distribution
or rights, or (y) such reclassification, reorganization, consolidation, merger,
conveyance, lease or transfer, dissolution, liquidation or winding up is to
take place and the date, if any, is to be fixed, or expected date as of which
the holders of Common Shares of record shall be entitled to exchange their
Common Shares for securities or other property deliverable upon such
reclassification, reorganization, consolidation, merger, conveyance, lease or
transfer, dissolution, liquidation or winding up.

     8.   REGISTRATION

          8.1 Definitions. For purposes of this paragraph 8:

          (a) The term "Act" means the Securities Act of 1933, as amended;

          (b) The terms "register", "registered" and "registration" refer to a
registration effected by preparing and filing a registration statement in
compliance with the Act and the declaration or ordering of effectiveness of
such registration statement;

          (c) The term "Registrable Securities" means this Warrant, the Warrant
Shares and any capital stock of the Company issued as a dividend or other
distribution with respect to, or in exchange or in replacement of; this Warrant
and/or the Warrant Shares; and

          (d) The term "Holder" means any holder of this Warrant and/or Warrant
Shares.


<PAGE>   6
          (e) The term "Warrant" shall mean this Warrant with all other
purchase warrants of like tenor, (differing, however, as to date, identity of
holders and number of shares purchasable) originally issued simultaneously with
the original predecessor of this Warrant.

          8.2 Piggy-back. During the three-year period commencing on the
Commencement Date of this Warrant and ending on the Expiration Date of this
Warrant, the Company shall advise each holder of Warrants or Warrant Shares, at
least thirty (30) days prior to any date on which the Company proposes to
register any of its equity securities under the Act on a registration form
usable for resales (other than on Form S-8 or other form similar thereto
relating to employee benefit plans or Form S-4 or similar forms used in
connection with business combinations). Upon the written request of any Holder
given within twenty (20) days after receipt of any such notice by the Company,
the Company shall use its best efforts to cause to be registered under the Act
all of the Registrable Securities that each such Holder has requested be
registered.

          Notwithstanding the foregoing, if the underwriter of such offering
determines that the total amount of securities which it and any other persons
or entities intend to include in such offering would adversely affect the
success of such offering, then the amount or kind of securities to be offered
by the holders of Warrant Shares and the holders of any other securities (the
"Other Securities") seeking to have such securities included in such
registration statement pursuant to the incidental registration rights of such
other holders shall be determined as follows: (i) there shall first be included
all Registrable Securities sought to be registered by holders thereof before
any Other Securities are included in such registration statement and there
shall then be included the Other Securities, and (ii) in the event that all
Registrable Securities cannot be so included, there shall be included
Registrable Securities pro rata to the extent necessary to reduce the total
amount recommended by such underwriters or excluded in their entirety, as the
case may be. In addition, if such registration statement relates to an
underwritten public offering and the number of shares to be offered is reduced
by the underwriter(s) subsequent to the initial filing thereof with the
Securities and Exchange Commission, the number of Registrable Securities to be
registered under such registration statement will be reduced pro rata.

          Further, the Company shall have the right at any time it shall have
given written notice pursuant to this Paragraph 8.2 (irrespective of whether a
written request for inclusion of Registrable Securities shall have been made)
to elect not to file any such proposed registration statement, or to withdraw
the same after the filing thereof.

          8.3  Covenants with Respect to Registration. In connection with any
registration under Paragraph 8.2, the Company covenants and agrees as follows:

               (a)  The Company shall use its best efforts to have any
registration statement declared effective remain effective for a period
adequate for all Holders to dispose of their Registrable Securities; provided,
however, that in connection with any proposed registration (i) intended to
permit an offering of any securities from time to time (i.e., a so-called
"shelf registration"), the Company shall in no event be obligated to cause any
such registration to remain effective for more


<PAGE>   7
than two hundred seventy (270) days, or (ii) covering the resales of the
Warrant Shares which are underwritten, the Company shall in no event be
obligated to cause any such registration to remain effective for longer than
the expiration of the distribution period of the Warrant Shares.

            (b)   The Company shall, to the extent provided for in this
agreement, prepare and file with the Securities and Exchange Commission ("SEC")
such amendments and supplements to such registration statement and the
prospectus used in connection with such registration statement as may be
necessary to comply with the provisions of the Act with respect to the
disposition of all securities covered by such registration statement.

            (c)   The Company shall furnish to the Holders such numbers of
copies of a prospectus, including a preliminary prospectus, in conformity with
the requirements of the Act, and such other documents as they may reasonably
request in order to facilitate the disposition of Registrable Securities owned
by them.

further provided that (anything in this Agreement to the contrary
notwithstanding with respect to the bearing of expenses) if any jurisdiction
in which the securities shall be qualified shall required that expenses

      8.5   Expenses. The Company shall pay all expenses incurred in connection
with a registration pursuant to the paragraph, including without limitation all

                      AMERICAN MULTIPLEXER(TM) CORPORATION

                        INCENTIVE STOCK OPTION AGREEMENT

     American Multiplexer(TM) Corporation, a California corporation (the
"Company"), has granted to ________________________ (the "Optionee"), an option
(the "Option") to purchase a total of _________________________ (_____________)
shares of Common Stock (the "Shares") of the Company on the terms and
conditions set forth below.

1.   Nature of the Option. This Option is intended to qualify as an Incentive
     Stock Option as defined in Section 422 of the Code.

2.   Exercise Price. The exercise price is __________________ for each share of
     Common Stock, which price is not less than the fair market value per share
     of the Common Stock on the date of grant.

3.   Exercise of Option. This Option shall be exercisable during its term as
     follows:

          (i)       Right to Exercise

               (a)  This Option shall be exercisable cumulatively, to the extent
                    of 25% on the one-year anniversary of the optionee's hire
                    date, and an additional 1/36 of the Shares on the last day
                    of each calendar month thereafter.

               (b)  Stock Acceleration

               There is stock ownership acceleration for the completion of
               agreed upon milestones in development, marketing, and sales. If
               milestones per the business plan are met, the ISO stock ownership
               will accelerate to vesting 50% of shares at completion of
               SatExpress Beta Field trials and completion of the Digicop-2
               development. The remaining 50% is proposed to accelerate with the
               launch of the SatExpress and DSL products into the full market
               place. The issued restricted stock warrants will accumulate at
               30% at start of any SatExpress Equipment Sales and the remaining
               20% at the completion of SatExpress Beta Field trials. An AMC
               Warrant agreement will be defined in a separate agreement.
               Otherwise, the ISO shares will vest normally at 25% per year as
               per section 3 (I)(a).

               (c)  This Option may not be exercised for a fraction of a share.

               (d)  Rights of Survivorship

               In the event of the optionee's death, disability or other
               termination of employment, other than cause, the rights to
               exercise the options will be transferable to the optionee's
               beneficiary or other designatee defined by the optionee.

     (ii) Merger, Consolidation or Sale of Assets. In the event of a proposed
sale of all or substantially all of the assets of the Company, or the merger of
the Company with or into another corporation, the Company shall provide
Optionee with written notice of such transaction not later


1998-99 American Multiplexer(TM) Corp. Confidential-Stock Option Agreement
                                                                     Page 1 of 4
<PAGE>   2
than thirty (30) days prior to the projected date of such transaction.
Notwithstanding the vesting provisions of Section 3(i)(a)(b) above, after
delivery of such notice Optionee may exercise this Option to the full extent.
After delivery of such notice, the optionee can, upon providing notice,
accelerate vesting at 100% on or prior to the date of such transaction and may
condition his exercise upon the occurrence of the transaction. Whether or not
so exercised, this Option agreement shall terminate immediately upon the
consummation of such proposed sale, merger or offering.

(iii)     Method of Exercise of Options. This Option shall be exercisable by
written notice which shall state the election to exercise the Option, the
number of Shares in respect of which the Option is being exercised, and such
other representations. Such written notice shall be signed by the Optionee and
shall be delivered in person or by certified mail to the Secretary of the
Company or designee. The written notice shall be deemed to be exercised upon
receipt by the Company of such written notice accompanied by the exercise price
at the fair market value at the time of exercise. Exhibit A contains the form
that should be used.

No shares will be issued pursuant to the exercise of an Option unless such
issuance and such exercise shall comply with all relevant provisions of law and
the requirements of any stock exchange upon which the Shares may then be
listed. Assuming such compliance, for income tax purposes the Shares shall be
considered transferred to the Optionee on the date on which the Option is
exercised with respect to such Shares.

4.   Method of Payment. Payment of the exercise price shall be by cash, check,
     or delivery of Common Stock of the Company that has been vested by the
     Optionee. The value of such common stock shall have a fair market value
     equal to the exercise price payable with respect to the exercise hereof or
     any combination of such methods of payment.

5.   Termination of Status as an Employee. In the event of termination of
     Optionee's status as an employee, he may, but only within one
     hundred-eighty (180) days after date of such termination, exercise this
     option to the extent that he was entitled to exercise it at the date of
     such termination. To the extent that he was not entitled to exercise this
     option at the date of such termination, or if he does not exercise this
     Option within the time specified herein, the Option shall terminate.

6.   Disability of Optionee. Notwithstanding the provisions of Section 5 above,
     in the event of termination of Optionee's status as an employee as a result
     of disability, he may, but only within six months from the date of
     termination of employment, exercise his Option to the extent he was
     entitled to exercise it at the date of such termination. To the extent that
     he was not entitled to exercise the Option at the date of termination, or
     if he does not exercise such Option within the time specified herein, the
     Option shall terminate.

7.   Death of Optionee. In the event of the death of Optionee, the Option may be
     exercised, at any time within six months following the date of death, by
     Optionee's estate, spouse or by a person who acquired the right to exercise
     the Option by bequest or inheritance but only to the extent of the right to
     exercise that has accrued at the date of death of the Optionee. To the
     extent that an Optionee was not entitled to exercise the Option at the date
     of his death, or if the Optionee's estate or legatee does not exercise the
     Option within the time specified herein, the Option shall terminate.

                                                                     Page 2 of 4

<PAGE>   3
8.    Non-Transferability of Option. This Option may not be transferred in any
      manner otherwise than by will or by the laws of descent or distribution
      and may be exercised during the lifetime of Optionee only by him. The
      terms of this Option shall be binding upon the executors, administrators,
      heirs, successors and assigns of the Optionee.

9.    Term of Option. This Option may not be exercised more than ten (10) years
      from the date of grant of this Option, and may be exercised during such
      term only in accordance with the Plan and the terms of this Option.

10.   Early Disposition of Stock. Optionee understands that if he disposes of
      any Shares received under this Option within two years after the date of
      this Agreement or within one year after such Shares were transferred to
      him, he will be treated for federal income tax purposes as having received
      ordinary income at the time of such disposition in an amount generally
      measured by the difference between the price paid for the Shares and the
      lower of the fair market value of the Shares at the date of the exercise
      or the fair market value of the Shares at the date of the disposition.
      Optionee understands that if he disposes of such Shares at any time after
      the expiration of such two-year and one-year holding periods, any gain on
      such sale will be taxed as long-term capital gain.

                     AMERICAN MULTIPLEXER(TM) CORPORATION,
                       RESTRICTED STOCK WARRANT AGREEMENT


      American Multiplexer(TM) Corporation, a California corporation (the
"Company"), has granted to Douglas R. Hanson (the "Warrantee"), a warrant (the
"Warrant") to purchase a total of One Million (1,000,000) shares of Common
Stock (the "Shares") of the Company on the terms and conditions set forth below.

1.    Nature of the Warrant: This Warrant is intended to qualify according to
      SEC rules.

2.    Exercise Price: The exercise price will be $1.00 per share.

3.    Right to Exercise Warrant: The Warrant is granted by the Company based on
      the intent of the Parties to the Warrant for the company to enter into a
      new business and to accomplish certain goals and objectives some of which
      are identified in the Descriptive Memorandum (c)1998. Warrantee shall
      accumulate the right to exercise the shares of the Warrant based on a) the
      Company's stock increasing in price over time, and/or b) the Company's
      achievement of certain milestones as identified herein. Said rights may be
      exercised independently based on the following set of conditions:

            (a)   Stock Price. The right to exercise up to 50% of the warrant
      (500,000 shares) is based on the following stock price milestones (with a
      base of 20 million shares in the company), whereby the stock maintains an
      average price on the OTC BB or other market for a period of 30 days:

            Stock Price @ $1.00 per share - 100,000 shares exercisable
            Stock Price @ $3.00 per share - 100,000 shares exercisable
            Stock Price @ $5.00 per share - 100,000 shares exercisable
            Stock Price @ $10.00 per share - 100,000 shares exercisable
            Stock Price @ $20.00 per share - 100,000 shares exercisable

            The above stock prices will be adjusted downward proportionally if
      the base of 20 million shares increases in the future.

            (b)   Marketing and Technical Milestones. The right to exercise up
      to 50% of the warrant (500,000 shares) is based on the Company achieving
      the following marketing, sales and engineering milestones. The achievement
      of the milestones is subject to the availability of funding to support the
      development and sales efforts as specified herein., and is based on time
      following the expenditure of said funds. If the funding is delayed, the
      technical or marketing milestone date is also delayed, but such change in
      milestone date does not cancel or void the Warrant.

     delivery of such notice, the warrantee can, upon providing notice,
     accelerate vesting at 100% of the full value of the warrant on or prior to
     the date of such transaction and may condition his exercise upon the
     occurrence of the transaction. Whether or not so exercised, this Warrant
     agreement shall terminate immediately upon the consummation of such
     proposed sale, merger or offering.

6.   Method of Exercise of Warrants. This Warrant shall be exercisable by
     written notice which shall state the election to exercise the Warrant, the
     number of Shares in respect of which the Warrant is being exercised, and
     such other representations. Such written notice shall be signed by the
     Warrantee and shall be delivered in person or by certified mail to the
     Secretary of the Company or designee. The written notice shall be deemed to
     be exercised upon receipt by the Company of such written notice accompanied
     by the exercise price at the fair market value at the time of exercise.
     Exhibit A contains the form that should be used. No shares will be issued
     pursuant to the exercise of an Warrant unless such issuance and such
     exercise shall comply with all relevant provisions of law and the
     requirements of any stock exchange upon which the Shares may then be
     listed. Assuming such compliance, for income tax purposes the Shares shall
     be considered transferred to the Warrantee on the date on which the Warrant
     is exercised with respect to such Shares.

7.   Method of Payment. Payment of the exercise price shall be by cash, check,
     or delivery of Common Stock of the Company that has been vested by the
     Warrantee. The value of such common stock shall have a fair market value at
     least equal to the exercise price payable with respect to the exercise
     hereof or any combination of such methods of payment.

8.   Termination of Status as an Employee.

          a)   Termination without Cause: In the event of termination without
     cause of the warrantee's status as an employee, the full value of this
     warrant will be exercisable.

          b)   Termination with Cause. In the event of termination with cause of
     Warrantee's status as an employee, he may, but only within one
     hundred-eighty (180) days after date of such termination, exercise this
     warrant to the extent that he was entitled to exercise it at the date of
     such termination. To the extent that he was not entitled to exercise this
     warrant at the date of such termination, or if he does not exercise this
     Warrant within the time specified herein, the Warrant shall terminate.

9.   Disability of Warrantee. Notwithstanding the provisions of Section 8 above,
     in the event of termination of Warrantee's status as an employee as a
     result of disability, he may, but only within six months from the date of
     termination of employment, exercise his Warrant to the extent he was
     entitled to exercise it at the date of such termination. To the extent that
     he was not entitled to exercise the Warrant at the date of termination, or
     if he does not exercise such Warrant within the time specified herein, the
     Warrant shall terminate.

10.  Death of Warrantee. In the event of the death of Warrantee, the Warrant may
     be exercised, at any time within six months following the date of death, by
     Warrantee's estate, spouse or by a person who acquired the right to
     exercise the Warrant by bequest or inheritance but only to the extent of
     the right

                                                                     Page 2 of 4

     to exercise that has accrued at the date of death of the Warrantee. To the
     extent that Warrantee was not entitled to exercise the Warrant at the date
     of his death, or if the Warrantee's estate or legatee does not exercise the
     Warrant within the time specified herein, the Warrant shall terminate.

11.  Transferability of Warrant. This Warrant may not be transferred in any
     manner otherwise than by will or by the laws of descent or distribution and
     may be exercised during the lifetime of Warrantee only by him. The terms of
     this Warrant shall be binding upon the executors, administrators, heirs,
     successors and assigns of the Warrantee.

12.  Term of Warrant. This Warrant may not be exercised more than ten (10) years
     from the date of grant of this Warrant, and may be exercised during such
     term only in accordance with the Plan and the terms of this Warrant.

13.  Early Disposition of Stock. Warrantee understands that if he disposes of
     any Shares received under this Warrant within two years after the date of
     this Agreement or within one year after such Shares were transferred to
     him, he will be treated for federal income tax purposes as having received
     ordinary income at the time of such disposition in an amount generally
     measured by the difference between the price paid for the Shares and the
     lower of the fair market value of the Shares at the date of the exercise or
     the fair market value of the Shares at the date of disposition. Warrantee
     understands that if he disposes of such Shares at any time after the
     expiration of such two-year and one-year holding periods, any gain on such
     sale will be taxed as long-term capital gain.
