     The following summary is qualified in its entirety by the more detailed
information, including "Risk Factors" and the Consolidated Financial Statements
and Notes thereto, appearing elsewhere in this Prospectus. Except as otherwise
indicated, all information in this Prospectus assumes no exercise of the
Underwriters' over-allotment option and gives effect to the conversion of all
outstanding shares of the Company's Preferred Stock into Common Stock
automatically upon the completion of this offering. This Prospectus contains
forward-looking statements that involve risks and uncertainties. The Company's
actual results could differ materially from those anticipated in these
forward-looking statements as a result of certain factors, including those set
forth under "Risk Factors" and elsewhere in this Prospectus.
    
 
                                  THE COMPANY
 
   
     First Virtual Corporation provides a high quality, cost-effective Internet
video networking solution for the Next Generation Internet ("NGI") that
integrates video with voice and data, while leveraging existing network
infrastructures. The Company combines its expertise in real-time network systems
and video technology to extend the capabilities of Quality of Service ("QoS")
across existing network architectures, including Internet Protocol ("IP"),
Asynchronous Transfer Mode ("ATM") and Ethernet. A network based on an
architecture that supports QoS can simultaneously carry multiple video streams,
as well as voice and data. First Virtual's broad product line enables it to
deliver end-to-end solutions for a wide range of NGI applications, such as
distance learning, telemedicine, video marketing and video manufacturing. A
critical element of the Company's technology is its Multimedia Operating
Software ("MOS"), designed to guarantee network resources for real-time video
applications in the presence of voice and bursts of data packets on any network
capable of supporting QoS. The Company's high quality, easy-to-use video
networking systems are scaleable to multiple locations and thousands of users.
First Virtual's solution addresses its customers' requirement for high quality
interactive visual communications through a broad range of Internet video server
and video access products.
    
 
   
     The Internet was originally designed to support delay-tolerant data
transmission applications such as electronic mail. Until recently, the limited
bandwidth and QoS capabilities of this "first generation" Internet did not
support the implementation of interactive visual applications. The enhanced
communication enabled by interactive visual applications such as Internet video
networking can provide significant benefits in a broad range of environments.
These include distance learning, telemedicine, video marketing and video
manufacturing. As a result, the need for a "next generation" Internet to enable
end users at remote locations to learn and work across networks -- interactively
and in real time -- is becoming widely accepted. In response, network managers
have begun to implement Internet and Intranet networks with the considerably
greater bandwidth and support for QoS required to enable Internet video
networking applications. The Company collectively defines these implementations
of advanced networking infrastructures as the NGI. Current NGI implementations
include statewide ATM networks, campus and enterprise ATM backbones and ATM wide
area networks ("WANs") using T1, DS3 and OC3 links.
    
 
   
     The Company has global OEM relationships with Bay Networks, Inc. ("Bay
Networks") and Northern Telecom, Inc. ("Nortel") and has established
relationships with a number of VARs and systems integrators, including Bell
Atlantic Network Integration ("BANI"), British Telecommunications plc ("BT"),
Clover Communications, Inc., France Telecom, IBM Global Services, NEC
Corporation and Nippon Telephone and Telegraph ("NTT"). The Company has also
built a network of international distributors to sell, service and support its
products in more than 40 countries worldwide. The Company's solutions have been
deployed by a broad range of educational institutions, corporations and
government agencies, such as Virginia Tech (distance learning facilities); IBM
(headquarters facility in Armonk, New York); Peregrine Incorporated
(headquarters and multiple manufacturing facilities); and Shanghai Infoport
(government metropolitan network). In addition, the Company has recently
licensed technology from IBM to facilitate broadcast quality Internet video over
the NGI.

                                  RISK FACTORS
 
     This Prospectus contains forward-looking statements that involve risks and
uncertainties. The Company's actual results could differ materially from those
anticipated in these forward-looking statements as a result of certain factors,
including those set forth in the following risk factors and elsewhere in this
Prospectus. In addition to the other information in this Prospectus, the
following risk factors should be considered carefully in evaluating the Company
and its business before purchasing the Common Stock offered by this Prospectus.
 
LIMITED OPERATING HISTORY; CUMULATIVE LOSSES
 
   
     The Company has a limited operating history upon which an evaluation of the
Company and its prospects can be based. The Company was incorporated in October
1993 and first shipped its video networking products in 1995. The Company's
prospects must be considered in light of the risks, expenses and difficulties
encountered by companies in their early stage of development, particularly
companies in new and rapidly evolving markets and companies experiencing rapid
growth and expansion. To address these risks, the Company must, among other
things, continue to achieve market acceptance for its products, maintain
technological leadership, respond to evolving markets and competition and
attract, retain and motivate qualified employees. There can be no assurance that
the Company will be successful in addressing these risks. The Company has
incurred substantial net losses in each quarter since its inception. As of
December 31, 1997, the Company had an accumulated deficit of $14.5 million. In
addition, as of December 31, 1997, the Company had gross deferred tax assets of
approximately $5.8 million, consisting primarily of net operating loss
carryforwards. Based on a number of factors, including the lack of a history of
profits and the fact that the Company competes in a developing market that is
characterized by rapidly changing technology, management believes that it is
more likely than not that the Company will not be able to realize its deferred
tax assets, and thus a full valuation reserve has been recorded as of December
31, 1997. The Company's ability to achieve a consistent, profitable level of
operations depends on a number of factors, many of which are beyond the control
of the Company. There can be no assurance that the Company will be able to
achieve profitability. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
    
 
FLUCTUATIONS IN OPERATING RESULTS
 
   
     The Company has experienced, and will in the future experience,
fluctuations in revenues, gross margins and operating results. For example, the
Company adopted a strategy in the fourth quarter of 1996 to focus on a limited
number of substantial end-user projects, rather than on sales of a large number
of pilot and demonstration projects. The initial impact of this change in
strategy was a decrease in revenues from $3.9 million in the fourth quarter of
1996 to $2.7 million in the first quarter of 1997. Revenues increased during
each of the quarters in 1997, due primarily to higher revenues from large end
user projects sold through Bay Networks in the OEM channel. There can be no
assurance that revenues will continue to increase on a quarterly basis or at
all. The Company's gross margins have historically fluctuated from period to
period and are expected to continue to fluctuate in the future. Gross margins
are significantly influenced by a variety of factors, including product mix,
percentage of revenues derived from original equipment manufacturers ("OEMs")
versus distributors or resellers, pricing within the video networking industry
and the prices of significant components used in the Company's products.
    
 
     Various factors, in addition to those discussed above, contribute to the
fluctuations in revenues, gross margins and operating results, including
development of the market for video networking and for the Company's products,
the Company's success in developing, introducing and shipping new products and
product enhancements, the Company's success in accurately forecasting demand for
new orders (which may have short lead-times before required shipment), new
product introductions and price reductions by its competitors, production
volumes and quality levels, seasonality, changes in material costs, the efforts
of OEMs, distributors, resellers, contract manufacturers and component suppliers
on behalf of the Company, the Company's ability to attract, retain and motivate
qualified personnel, the
 
                                        6
<PAGE>   8
 
timing and amount of research and development and selling, general and
administrative expenditures, and general economic conditions.
 
   
     Further, a significant portion of the Company's expenses are fixed in
advance. The Company expects that operating expenses will increase in the future
to fund expanded operations. To the extent these increased expenses are not
accompanied by an increase in revenues, the Company's business, financial
condition and results of operations could be materially adversely affected. If
revenues or gross margins are below Company expectations in any given period,
the Company's inability to adjust operating expenses in response would adversely
affect operating results. Due to all the foregoing factors, it is likely that in
some future quarter, the Company's results of operations will be below the
expectations of public market analysts and investors. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
    
 
MARKET ACCEPTANCE OF VIDEO NETWORKING
 
     The Company's success depends on the market acceptance of video networking.
Potential end-users must accept video applications as a viable alternative to
face-to-face meetings and conventional classroom based learning. New
applications, such as the use of video in marketing, selling and manufacturing,
are in an early stage of development and have not been widely accepted to date.
Early video networking equipment designed for local area networks ("LANs")
suffered from poor video quality, as has traditional Integrated Services Digital
Network ("ISDN") based video conferencing, adversely affecting widespread
acceptance of video networking applications. The Company must overcome this
negative perception. Potential end-users must be educated in the use and
benefits of video networking. If video networking fails to achieve broad
commercial acceptance or such acceptance is delayed, the Company's business,
financial condition and results of operations would be materially adversely
affected. See "Business -- Industry Background."
 
   
DEPENDENCE ON ATM BACKBONE TECHNOLOGY AND THE NEXT GENERATION INTERNET
    
 
   
     Although ATM is becoming widely adopted as the backbone technology for NGI
networks, video networking over ATM networks is still an emerging market and the
NGI is still emerging. The Company currently derives a significant amount of its
revenues from its video networking products that function over the NGI and ATM
backbones, and sales of these video networking products are expected to continue
to account for a significant amount of the Company's revenues for the
foreseeable future. The Company's business strategy is based on the assumption
that ATM backbone technology will be a widely accepted networking backbone
solution. Accordingly, the Company's business, financial condition and results
of operations are dependent on continued growth and market acceptance of ATM
technology as a networking backbone, as well as on the widespread emergence of
the NGI. The market acceptance of ATM technology may be adversely influenced by
the availability, performance and price of competing technologies such as Fast
Ethernet and Gigabit Ethernet. There can be no assurance that there will be
continued growth and market acceptance of ATM technology or the Company's video
networking products. In the event that ATM backbone networks fail to achieve
broad commercial acceptance or in the event of the failure to achieve widespread
emergence of the NGI on a timely basis, or at all, the Company's business,
financial condition and results of operations could be materially adversely
affected.
    
 
DEPENDENCE ON DISTRIBUTION RELATIONSHIPS
 
   
     The Company currently focuses on sales through OEMs, distributors and
resellers ("distribution relationships"). The Company's future performance will
depend in large part on sales of its products through its distribution
relationships, such as Bay Networks, Nortel, and other key partners. During the
year ended December 31, 1997, Bay Networks was the Company's most significant
OEM, representing 64% of the Company's revenues. In November 1995, the Company
granted Bay Networks the worldwide non-exclusive right to market and sell
certain of the Company's products. In September 1996, the Company granted Bay
Networks the worldwide non-exclusive right to market and sell all of
    
                                        7
<PAGE>   9
 
   
the Company's current and future products under both the Company's and Bay
Networks' names. In May 1997, the Company granted similar rights to Nortel to
market the Company's products under the Company's name. In addition, in February
1998, the Company entered into a reference selling agreement with International
Business Machines ("IBM") pursuant to which IBM will refer customers to FVC or
recommend that FVC contact a particular customer. The Company expects, based on
its past experience, that new distribution relationships, such as the Nortel
relationship and the reference selling relationship with IBM, generally will not
result in significant sales in the short term, but only after a period during
which the Company trains the partners' sales forces and helps identify sales
opportunities. Agreements with Bay Networks, Nortel and other distribution
partners generally provide for discounts based on the Company's list prices, and
do not require minimum purchases. These agreements do not restrict development
or distribution of competitive products. Therefore, some of the entities which
distribute the Company's products may compete with the Company. The Company
cannot assure that an OEM, distributor or reseller will dedicate sufficient
resources or give sufficient priority to selling the Company's products. While
the Company plans to seek additional distribution relationships, these
relationships could compete with and adversely affect sales by the Company's
existing OEMs, distributors or resellers. The Company depends on its
distribution relationships for most customer support, and expends significant
resources to train its OEMs, distributors and resellers to support their
customers. These entities can generally terminate the distribution relationship
upon 30 days notice for a material breach. The loss of a distribution
relationship or a decline in the efforts of a material distributor could have a
material adverse effect on the Company's business, operating results and
financial condition. See "Business -- Marketing, Sales and Customer Support."
    
 
LIMITED NUMBER OF LARGE PROJECTS; LENGTHY SALES AND IMPLEMENTATION CYCLE
 
     The Company depends on a limited number of large end-user projects for a
majority of its revenues, which has resulted in, and may in the future result
in, significant fluctuations in quarterly revenues. For example, a sale to IBM's
corporate headquarters represented nine percent of the Company's revenues in the
second quarter of 1997. The Company expects that revenues from the sale of
products to large end-users will continue to account for a significant
percentage of its revenues in any particular quarter for the foreseeable future.
Additionally, a significant portion of the Company's sales of video networking
products has historically been to government-related agencies, such as military
and educational institutions, or third parties using the Company's products on
behalf of government agencies. Such government-related customers are often
subject to budgetary pressures and may from time to time reduce their
expenditures and/or cancel orders. The loss of any major customer, or any
reduction or delay in orders by such customer, or the failure of the Company or
its distribution partners to market its products successfully to new customers
could have a material adverse effect on the Company's business, financial
condition and results of operations. See "Business -- Customers and
Applications."
 
     Sales of the Company's products require an extended sales effort. The
Company must first train the entities with which it has distribution
relationships to market the Company's products. These entities then must
identify appropriate video networking opportunities and compete for prospective
customers' scarce management attention and resources. Since the Company's
products are often used as part of a larger project and must be installed
without adversely affecting the performance of the customer's existing network,
end-users often require time to decide whether to undertake the project. Due to
operating procedures in many large organizations, particularly government
agencies, an extended time period may elapse after key decision makers have
selected the Company's products and before a contract to purchase the Company's
products can be signed. As a result, the period from an initial sales call to an
end-user agreement typically ranges from six to twelve months, and can be
longer. Therefore, the timing of revenues may be unpredictable. This could have
a material adverse effect on the Company's business, financial condition and
results of operations.

<PAGE>   10
 
RAPID TECHNOLOGICAL CHANGE; DEPENDENCE ON NEW PRODUCTS
 
     The markets for the Company's products are characterized by rapid
technological change and evolving industry standards. The Company's success will
depend, in part, on its ability to maintain its technological leadership, to
enhance and expand its existing product offerings and to develop and introduce
in a timely manner new products which achieve market acceptance. The development
of new, technologically advanced products is a complex and uncertain process
requiring high levels of innovation, as well as the accurate anticipation of
technological and market trends. The Company has experienced delays in the
introduction of new products in the past and may in the future experience such
delays.
 
     As technology changes, the Company's success will also depend in part upon
its ability and the ability of its strategic partners to comply with evolving
industry standards. Transmission Control Protocol/Internet Protocol ("TCP/IP")
industry standards, such as H.323, Resource Reservation Protocol ("RSVP") and
Real-Time Protocol ("RTP"), are evolving. These standards potentially afford an
alternative to the Company's current video networking solutions. Industry
standards for Asynchronous Transfer Mode ("ATM"), such as H.321, LAN Emulation
("LANE"), Multi-Protocol Over ATM ("MPOA") and Private Network-Network Interface
("PNNI") are also still evolving. As standards evolve, the Company must modify
its products, or develop and support new versions of its products. The failure
of the Company's products to comply, or delays in achieving compliance, with
various evolving industry standards could delay introduction of the Company's
products, which could have a material adverse effect on the Company's business,
financial condition and results of operations. The Company's ability to compete
successfully is also dependent upon the continued compatibility and
interoperability of its products with products and architectures offered by
various vendors. The Company's business, financial condition and results of
operations would be materially adversely affected if it were to incur
significant delays or be unsuccessful in developing new products or
enhancements, if any such products or enhancements did not gain market
acceptance or if the Company is unable to effectively address the compatibility
and interoperability issues raised by technological changes in a timely manner,
or if a delay in the creation of industry standards resulted in customers
deciding not to deploy, or to delay deployment of, the Company's products. In
addition, there can be no assurance that products or technologies developed by
others will not render the Company's products noncompetitive or obsolete.
 
   
     From time to time, the Company may announce new products, capabilities or
technologies that have the potential to replace or shorten the life cycle of the
Company's existing product offerings. The announcement of product enhancements
or new product offerings could cause customers to defer purchasing the Company's
products. For example, the Company is currently developing products for
Ethernet/IP-based networks, such as the V-Gate 323, which may delay or defer
implementation of the Company's existing ATM-based products. The failure of the
Company to introduce new products or product enhancements effectively and on a
timely basis, customer delays in purchasing products in anticipation of new
product introductions and any inability of the Company to respond effectively to
technological changes, or to comply with the various existing and evolving
industry standards, or product announcements by competitors, could have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Business -- First Virtual's Products and Technology"
and "-- Research and Development."
    
 
   
DEPENDENCE ON SUPPLIERS
    
 
     Several of the critical components used in the Company's products,
including certain custom and programmable semiconductors, such as the Pisces
ASIC, the SESAR ASIC and an ATM adapter, are currently available only from
Lucent Technologies Inc. ("Lucent"), Integrated Telecom Technology, Inc. ("IgT")
and Integrated Device Technologies, Inc. ("IDT"), respectively. The Company does
not have long-term agreements with these suppliers, and they are not obligated
to provide components to the Company for any specific period, in any specific
quantity or at any specific price, except as may be provided in a particular
purchase order. Qualifying additional suppliers is a time consuming and
expensive process, and there is a greater likelihood of problems arising during
a transition period to a
 
                                        9
<PAGE>   11
 
new supplier. There can be no assurance that these existing suppliers will
continue to meet the Company's requirements for these components. Any
interruption in the supply of these components, or the inability of the Company
to procure these components from alternate sources at acceptable prices and
within a reasonable period of time, or any excessive rework costs associated
with defective components or process errors, would have a material adverse
effect on the Company's business, financial condition and results of operations.
 
     The Company uses a product sales forecast based on anticipated product
orders to determine its components requirements. As a result of the relatively
short lead-time on certain orders, however, this forecast may not be accurate.
Certain components used in the Company's products require an order lead time of
up to 16 weeks. Other components that currently are readily available may become
difficult to obtain in the future. Failure of the Company to predict accurately
its required quantities of these components could result in either shortages or
excess inventory of such components, as well as cause the Company to delay
shipments of its products in response to orders, which could have a material
adverse effect on the Company's business, financial condition and results of
operations. The Company has from time to time experienced shortages of certain
other key components. These component shortages have resulted in delays in the
shipment of the Company's products, and the component shortages have also
resulted in higher component costs. When these components are in short supply,
the Company must compete for them with companies that have greater purchasing
power and often have longer established relationships with their vendors. There
can be no assurance that the Company will not experience shortages in component
supplies in the future, which would have a material adverse affect on the
Company's business, financial condition and results of operations.
 
COMPETITION; INDUSTRY CONSOLIDATION
 
   
     The video networking industry is becoming increasingly competitive. As an
end-to-end high quality ATM-based video networking solution, First Virtual's
products face actual and potential competition in different market segments. The
Company's most direct competitors also currently offer video networking over
ATM, including FORE Systems, Inc. ("FORE") and Newbridge Networks Corporation
("Newbridge"). The Company's video networking products also compete with systems
based on other technologies, such as the ISDN-based video networking products
offered by Madge Networks, N.V. ("Madge"). The Company's video access products,
when sold by its distribution partners such as Bay Networks, are used to compete
with ATM-based infrastructure products sold by companies such as Cisco Systems,
Inc. ("Cisco") and 3Com Corporation ("3Com"). In the interactive video area, the
Company's technology licensing agreement with IBM is intended to result in
products which would compete with products sold by companies such as Newbridge
in the high-end H.310 videoconferencing market. In video storage, the Company's
V-Cache products face competition from companies which offer high-performance
servers that can store video, such as Silicon Graphics, Inc. ("SGI"), Starlight
Networks Inc. ("Starlight"), Sun Microsystems, Inc. ("Sun") and The Network
Connection ("TNC"). In the video broadcast area, the Company's products compete
with system and software products of companies which provide "streamed" video
over IP/Ethernet networks, such as Optivision, Inc. ("Optivision") and Precept
Software, Inc. ("Precept Software"). The Company faces potential competition
from large companies which have products in related areas, such as Intel
Corporation ("Intel") and Microsoft Corporation ("Microsoft"). The Company could
encounter new competition if companies which distribute First Virtual's
products, or whose interactive video equipment is used together with the
Company's products, develop or acquire video networking technologies or
products. There can be no assurance that the Company will be able to compete
successfully in this environment.
    
 
     Many of the Company's actual and potential competitors have greater name
recognition; a larger installed base of networking products and strong
relationships with end users; more extensive engineering, manufacturing,
marketing and distribution capabilities; and greater financial, technological
and personnel resources than the Company. The networking industry is undergoing
a period of consolidation in which companies, including some of the Company's
competitors, are participating in
 
                                       10
<PAGE>   12
 
business combinations, resulting in competitors with larger market shares,
customer bases, sales forces, product offerings and technology and marketing
expertise.
 
     The Company's principal method of competition is product performance. To
compete effectively, First Virtual must continue to offer an end-to-end
solution, provide high-performance products which comply with applicable
standards and are easy to use, and expand its product distribution channels
domestically and internationally. There can be no assurance that the Company
will be able to compete effectively on these bases.
 
     In addition, the Company expects price competition to escalate in the video
networking industry. Although the Company has rarely lowered product prices in
the past, anticipated competition may force the Company in the future to lower
product prices on a regular basis and add new products and features without
increasing prices. There can be no assurance that the Company will be able to
compete successfully in such a price competitive environment. If such pricing
pressures are not mitigated by cost reduction or changes in product mix, the
Company's business, financial condition and results of operations would be
materially adversely affected. See "Business -- Competition."
 
COMPLIANCE WITH INDUSTRY STANDARDS AND REGULATIONS
 
     The Company's products must meet a significant number of video, voice and
data communications regulations and standards, some of which are evolving as new
technologies are deployed. In the United States, the Company's products must
comply with various regulations defined by the Federal Communications Commission
and Underwriters Laboratories. Internationally, the Company's products must
comply with standards established by telecommunications authorities in various
countries, as well as with recommendations of the International
Telecommunications Union. The Company's products are currently in compliance
with applicable regulatory requirements. However, there can be no assurance that
such regulatory requirements will not in the future impose additional or
different regulations or standards on sales of the Company's products. In
addition, telecommunications service providers require that equipment connected
to their networks comply with their own standards, which may vary from industry
standards. A delay in obtaining, or the failure to obtain, certification of its
products domestically or in countries outside of the United States, or a delay
in or failure to comply with applicable regulatory requirements, could delay or
preclude the Company's marketing and sales efforts, which could have a material
adverse effect on the Company's business, financial condition and results of
operations.
 
     TCP/IP industry standards, such as H.323, RSVP and RTP, are evolving. These
standards potentially afford an alternative to the Company's current video
networking solution. Industry standards for ATM, such as H.321, LANE, MPOA and
PNNI, are also still evolving. As these standards evolve, the Company must
modify its products, or develop and support new versions of its products. The
failure of the Company's products to comply, or delays in achieving compliance,
with the various existing and evolving industry standards could delay
introduction of the Company's products, which could have a material adverse
effect on the Company's business, financial condition and results of operations.
 
     Government regulatory policies are likely to continue to have a major
impact on the pricing of services over existing and new public ATM network
infrastructures and, therefore, are expected to affect demand for applications
such as video networking. Tariff rates, whether determined autonomously by
telecommunications service providers or in response to regulatory directives,
may affect the cost effectiveness of deploying public ATM network services.
Tariff policies are under continuous review and are subject to change. User
uncertainty regarding future policies could decrease demand for
telecommunications products, including the Company's products, which would have
a material adverse effect on the Company's business, financial condition and
results of operations.
 
RELIANCE ON INTELLECTUAL PROPERTY
 
     The Company's success and ability to compete in the video networking
industry depends, in part, upon its ability to protect its proprietary
technology and to operate without infringing the proprietary rights of others.
The Company does not rely on patent protection for, and does not hold, any
patents relating to its products. The Company's adherence to industry-wide
technical standards and specifica-
 
                                       11
<PAGE>   13
 
tions may limit the Company's opportunities to provide proprietary product
features. The Company currently licenses certain technology from third parties
and plans to continue to do so in the future. The commercial success of the
Company will also depend, in part, on the Company not breaching its current and
future licenses of third-party technology used in certain of the Company's
products.
 
     The Company currently relies upon a combination of trade secret, copyright
and trademark laws and contractual restrictions to establish and protect
proprietary rights in its products. The Company also enters into confidentiality
and invention assignment agreements with its employees and enters into
non-disclosure agreements with its suppliers, distributors and customers to
limit access to and disclosure of its proprietary information. There can be no
assurance that these statutory and contractual arrangements will be sufficient
to deter misappropriation of the Company's proprietary technologies or that
independent third-parties will not develop similar or superior technologies. The
development of alternative technologies by third parties could adversely affect
the competitiveness of the Company's products. In addition, the laws of some
countries do not provide the same degree of protection of the Company's
proprietary information as do the laws of the United States.
 
     The Company is also subject to the risk of litigation alleging infringement
of third party intellectual property rights from both its licensed and
proprietary technology. A number of companies have developed technologies or
received patents on technologies that may be related to or be competitive with
the Company's technologies. The Company has not conducted a patent search
relating to the technology used in its products. In addition, since patent
applications in the United States are not publicly disclosed until the patent
issues, applications may have been filed which, if issued as patents, would
relate to the Company's products. Many of these companies have significantly
greater resources than the Company. Given the rapid development of technology in
the video networking industry, there can be no assurance that the Company's
existing or future products will not infringe upon the existing or future
proprietary rights of others. Further, the Company's lack of patents may inhibit
the Company's ability to negotiate or obtain licenses from or oppose patents of
third parties, if necessary. The Company could incur substantial costs in
defending itself and its customers against any such claims, regardless of the
merits of such claims. The Company may be required by contract or by statutory
implied warranties to indemnify its distribution partners and end-users against
third-party infringement claims. Parties making such claims may be able to
obtain injunctive or other equitable relief which could effectively block the
Company's ability to sell its products in the United States and abroad, and
could result in an award of substantial damages. In the event of a successful
claim of infringement, the Company, its customers and end-users may be required
to obtain one or more licenses from third parties. There can be no assurance
that the Company or its customers could obtain necessary licenses from third
parties at a reasonable cost, or at all. The defense of any lawsuit could result
in time-consuming and expensive litigation, damages, license fees, royalty
payments and restrictions on the Company's ability to sell its products, any of
which could have a material adverse effect on the Company's business, financial
condition, and results of operations. See "Business -- Intellectual Property."
 
DEPENDENCE ON THIRD PARTIES FOR MANUFACTURING
 
   
     The Company currently outsources the manufacturing of its products. The
Company relies on three vendors, Tanon Manufacturing, Inc. ("Tanon"), Empac
International Corporation ("Empac") and PCB Assembly Corporation ("PCB"), to
turnkey manufacture certain of its products. If one or more of these
manufacturers experiences quality or other problems, product shipments by the
Company may be delayed. The Company has experienced such delays in the past and
may in the future experience delays. If the Company is required to find
replacements for its manufacturers, such change in manufacturers could result in
short-term cost increases and delays in delivery, which could have a material
adverse effect on the Company's business, financial condition and results of
operations. The Company maintains a safety stock of critical components and
reserve inventory, which would not be sufficient to meet increases in demand
occurring simultaneously with delayed deliveries from manufacturers. There can
be no assurance that the Company will be able to negotiate acceptable
    
 
                                       12
<PAGE>   14
 
arrangements with its existing or any future manufacturers, or, if negotiated,
that such arrangements will be on terms favorable to the Company. See
"Business -- Manufacturing."
 
MANAGEMENT OF GROWTH; DEPENDENCE ON THIRD PARTY OUTSOURCING
 
   
     The Company's growth, both in sales and in the number of its employees, has
placed, and is expected to continue to place, a significant strain on its
managerial, financial and personnel resources. The Company presently has fewer
than 75 full-time employees. The Company's ability to compete effectively and to
manage future growth, if any, will require the Company to continue to improve
its financial and management controls, reporting systems and procedures on a
timely basis, to expand, train and manage its employees, and to respond rapidly
to customer needs, including providing support for the Company's products. There
can be no assurance that the Company will be able to compete effectively and
manage future growth.
    
 
     The Company currently outsources certain human resources and financial
responsibilities. The Company's accounting and data processing functions are
performed by KPMG Peat Marwick LLP ("KPMG"). While the Company has experienced
turnover with respect to the persons providing the services on behalf of KPMG,
such turnover has not had a material impact on the Company's operations. There
can be no assurance that such turnover will not have a material impact in the
future, or that such relationship will not be terminated by KPMG. As part of the
responsibilities of becoming a public company, the Company may need to transfer
certain finance functions back to the Company or transition from KPMG to another
service provider, both of which may have a material adverse effect on the
Company's business, financial condition and results of operations. In addition,
the Company may in the future acquire additional businesses, products or
technologies. There can be no assurance that the Company will be able to manage
its expansion or integrate the operations of any businesses, products or
technologies it may in the future acquire. The failure to do so could materially
adversely affect the Company's business, financial condition and results of
operations.
 
DEPENDENCE ON KEY PERSONNEL; ABILITY TO ATTRACT AND RETAIN PERSONNEL
 
     The Company's success to date has been significantly dependent on the
contributions of a number of its key personnel, including Ralph Ungermann,
President and Chief Executive Officer, Allwyn Sequeira, Vice President,
Engineering and Chief Technical Officer and James O. Mitchell, Vice President,
Operations and Chief Financial Officer. The loss of the services of Messrs.
Ungermann, Sequeira or Mitchell could have a material adverse effect on the
Company. The Company's success also depends, to a significant extent, upon other
key employees, consultants and advisors. The loss of the services of one or more
of these key employees or consultants and advisors could have a material adverse
effect on the Company. None of the Company's employees, including its senior
management, is bound by an employment or non-competition agreement, and the
Company does not maintain "key person" life insurance on any employee.
 
     The Company believes that its future success will also depend upon its
ability to attract and retain additional highly-skilled technical, managerial,
manufacturing, sales and marketing personnel. Competition for such personnel is
intense. There can be no assurance that the Company will be able to anticipate
accurately, or to obtain, the personnel that it may require in the future. The
failure to obtain personnel, when necessary, could have a material adverse
effect on the Company's business, financial condition and results of operations.
See "Management."
 
RISK OF PRODUCT DEFECTS
 
     Products as complex as those offered by the Company frequently contain
undetected errors or defects, especially when first introduced or when new
versions or enhancements are released. Despite product testing by the Company
and its customers, the Company has in the past shipped product releases with
some defects, and has discovered other errors in its products after their
commercial shipment. Certain providers of the hardware and software used in the
Company's products in the past have changed their specifications, adversely
affecting the performance of the Company's products. For example, in the third
quarter of 1997, a semiconductor device supplier changed the design of its chip
 
                                       13
<PAGE>   15
 
without notifying the Company, halting production of certain of the Company's
products until the board incorporating this chip could be redesigned and
adversely affecting the Company's revenues for the quarter. There can be no
assurance that, despite testing by the Company and by current and potential
customers, defects and errors will not be found in new products or in new
versions or enhancements of existing products after commencement of commercial
shipments, or that the Company will not have to devote significant financial
resources and personnel to correct the defects. In addition, although the
Company currently carries product liability insurance in the aggregate amount of
$2 million, there can be no assurance that such insurance would be adequate in
the event of a product liability claim brought against the Company as a result
of any such defects or that the Company will be able to maintain such insurance.
A product liability claim brought against the Company could have a material
adverse effect upon the Company's business, financial condition and results of
operations. In addition, the Company's products incorporate and are used with
third party products. Defects, including those of third parties, discovered in
the future could result in adverse customer reaction, negative publicity
regarding the Company and its products, delays in implementation of the
Company's products, or delays in or failure to achieve market acceptance of the
Company's products, any of which could have a material adverse effect upon the
Company's business, financial condition and results of operations.
 
RISK OF INTERNATIONAL SALES AND CURRENCY FLUCTUATIONS
 
   
     Sales outside of North America accounted for approximately 36% and 20% of
the Company's revenues for the years ended December 31, 1996 and 1997,
respectively. There can be no assurance that revenues from international sales
will continue to constitute a significant portion of the Company's business. A
decline in international sales could have a material adverse effect on the
Company's business, financial condition and results of operations. In addition,
while the Company's current products are designed to meet relevant regulatory
requirements in markets outside of the United States in which they are sold, any
inability to obtain any such required regulatory approvals on a timely basis
could have a material adverse effect on the Company. Conducting business outside
of the United States is subject to certain risks, including seasonality, longer
payment cycles, changes in regulatory requirements and tariffs, reduced
protection of intellectual property rights, difficulties in distribution, the
burden of complying with a variety of foreign laws and political or economic
constraints on international trade or instability. There can be no assurance
that any of these factors will not have a material adverse effect on the
Company's business, financial condition and results of operations.
    
 
     All of the Company's sales are denominated in United States dollars.
Therefore, an increase in the value of the dollar relative to local currency
could increase the price in local currencies of the Company's products in
markets outside of the United States and make the Company's products relatively
more expensive than competitive products denominated in local currencies, which
could materially adversely affect the Company's business, financial condition
and results of operations.
 
ABSENCE OF PRIOR PUBLIC MARKET; VOLATILITY OF STOCK PRICE
 
     Prior to this offering there has been no public market for the Company's
Common Stock, and there can be no assurance that an active market will develop
or be maintained. The initial public offering price will be negotiated between
the Company and the representatives of the Underwriters and may not be
indicative of future market prices. See "Underwriting" for information related
to the method of determining the initial public offering price. The market price
of the shares of the Company's Common Stock, like that of the common stock of
many other high technology companies, is likely to be highly volatile. Factors
such as the Company's operating results, developments in the Company's
relationships with strategic partners, developments affecting the Company's
strategic partners, regulatory action or regulatory approval with respect to the
Company, its competitors or their products, announcements of new products by the
Company or its competitors, developments related to proprietary rights by the
Company or its competitors, changes in the recommendation of securities analysts
with respect to the Company's Common Stock, and market conditions for high
 
                                       14
<PAGE>   16
 
technology stocks in general may cause the market price of the Company's Common
Stock to fluctuate, perhaps substantially. The Company expects that operating
results will fluctuate from quarter to quarter and that such fluctuations may be
substantial. In addition, in recent years the stock market in general, and the
shares of high technology companies in particular, have experienced extreme
price fluctuations. Fluctuations in operating results, as well as these broad
market and industry fluctuations, may have a material adverse effect on the
market price of the Company's Common Stock.
 
CONTROL BY EXISTING STOCKHOLDERS
 
   
     After this offering, the Company's named executive officers, directors and
principal stockholders will beneficially own approximately 7,636,657, or 49.9%,
of the outstanding shares of Common Stock (48.7% if the underwriters'
overallotment option is exercised in full). As a result, such persons may have
the ability to effectively control the Company and direct its affairs and
business, including the election of directors and approval of significant
corporate transactions. Such concentration of ownership may also have the effect
of delaying, deferring or preventing a change in control of the Company, and
making certain transactions more difficult or impossible absent the support of
such stockholders, including proxy contests, mergers involving the Company,
tender offers, open-market purchase programs or other purchases of Common Stock
that could give stockholders of the Company the opportunity to realize a premium
over the then prevailing market price for shares of Common Stock. See "Principal
and Selling Stockholders."
    
 
BENEFITS OF THE OFFERING TO CURRENT STOCKHOLDERS
 
   
     This offering will provide substantial benefits to current stockholders of
the Company. Consummation of this offering is expected to create a public market
for the Common Stock held by the Company's current stockholders, including
directors and executive officers of the Company. Current stockholders paid
approximately $15.7 million for an aggregate of approximately 12,830,627 shares
of Common Stock as of March 31, 1998, of which the Company's directors,
executive officers and their respective affiliates beneficially own
approximately 7,671,657, or 58.6%, of the outstanding Common Stock prior to this
offering. This offering will result in a combined gross unrealized gain (not
including any realized gain by any such persons as Selling Stockholders) to such
stockholders in the aggregate amount of approximately $148.8 million, assuming
an initial public offering price of $13.00 per share. See "-- Absence of Prior
Public Market; Volatility of Stock Price," and "Dilution."
    
 
ANTI-TAKEOVER EFFECTS OF CERTAIN CHARTER PROVISIONS AND DELAWARE LAW
 
   
     Upon completion of this offering, the Company's Board of Directors will
have the authority to issue up to 5,000,000 shares of Preferred Stock and to
determine the price, rights, preferences and privileges of those shares without
any further vote or action by the Company's stockholders. The rights of the
holders of Common Stock will be subject to, and may be adversely affected by,
the rights of the holders of any Preferred Stock that may be issued in the
future. Any such issuance, while providing desirable flexibility in connection
with possible acquisitions and other corporate purposes, could affect adversely
the voting power of holders of Common Stock and the likelihood that such holders
will receive payments upon liquidation. Additionally, the issuance of Preferred
Stock could have the effect of making it more difficult for a third party to
acquire a majority of the outstanding voting stock of the Company and may
discourage bids for the Common Stock at a premium over the market price of the
Common Stock and may affect adversely the market price of and the voting and
other rights of the holders of the Common Stock. In addition, the Company is
subject to the anti-takeover provisions of Section 203 of the Delaware General
Corporation Law, which prohibits the Company from engaging in a "business
combination" with an "interested stockholder" for a period of three years after
the date of the transaction in which the person became an interested
stockholder, unless the business combination is approved in a prescribed manner.
The application of Section 203 could have the effect of delaying or preventing a
change of control of the Company. The Company's Certificate of Incorporation
also provides for staggered terms for the members of the Board of Directors.
These provisions, and
    
 
                                       15
<PAGE>   17
 
other provisions of the Certificate of Incorporation, the Company's Bylaws and
Delaware corporate law, may have the effect of deterring hostile takeovers or
delaying or preventing changes in control or management of the Company,
including transactions in which stockholders might otherwise receive a premium
for their shares over then current market prices.
 
SHARES ELIGIBLE FOR FUTURE SALE; REGISTRATION RIGHTS
 
   
     Sales of a substantial number of shares of Common Stock in the public
market following this offering could adversely affect the market price for the
Company's Common Stock. The number of shares of Common Stock available for sale
in the public market is limited by (i) restrictions under the Securities Act of
1933, as amended (the "Securities Act"), and (ii) 180-day lock-up agreements
pursuant to which all directors, officers and other stockholders of the Company
have agreed not to sell or otherwise dispose of any of their shares without the
prior written consent of BancAmerica Robertson Stephens or, in certain
instances, the Company. The Company has agreed with BancAmerica Robertson
Stephens not to release any stockholder from any lock-up agreement between the
stockholder and the Company without the prior written consent of BancAmerica
Robertson Stephens. 12,505,006 shares and an additional 691,504 shares issuable
upon exercise of outstanding vested options will be eligible for sale 180 days
after the date of this Prospectus upon expiration of the lock-up agreements and
in compliance with certain limitations set forth in the Securities Act. An
additional 145,621 of the outstanding shares will become eligible for sale at
various times after 180 days after the date of this Prospectus, over a period of
less than one year, pursuant to Rule 144 and Rule 701 under the Securities Act.
Additionally, 854,158 of the outstanding shares, that would otherwise be
eligible for sale as set forth above, are contractually restricted shares
subject to rights of repurchase in favor of the Company that expire at various
dates through July 25, 2001 pursuant to vesting requirements. After this
offering, the holders of approximately 10,749,153 shares of Common Stock and
warrants to purchase 185,936 shares of Common Stock will be entitled to certain
demand and piggyback registration rights with respect to registration of such
shares under the Securities Act. If such holders, by exercising their demand or
piggyback registration rights, cause a large number of securities to be
registered and sold in the public market, such sales could have an adverse
effect on the market price for the Company's Common Stock. If the Company were
to include in a Company initiated registration shares held by such holders
pursuant to the exercise of their piggyback registration rights, such sales may
have an adverse effect on the Company's ability to raise needed capital. See
"Shares Eligible For Future Sale" and "Description of Capital
Stock -- Registration Rights."
    
 
NO SPECIFIC PLAN FOR SIGNIFICANT PORTION OF PROCEEDS
 
     The Company currently has no specific plans for a significant portion of
the net proceeds of the offering. As a consequence, the Company's management
will have the discretion to allocate this portion of the net proceeds of this
offering to uses that the stockholders may not deem desirable, and there can be
no assurance that these proceeds can or will be invested to yield a significant
return. Substantially all of the proceeds of the offering will be invested in
short-term, interest-bearing, investment grade securities for an indefinite
period of time. See "Use of Proceeds."
 
FUTURE CAPITAL NEEDS; UNCERTAINTY OF ADDITIONAL FINANCING
 
     The Company currently anticipates that its available cash resources
combined with the net proceeds of this offering, together with funds from the
Company's existing line of credit, will be sufficient to meet its presently
anticipated working capital and capital expenditure requirements for at least
the next 12 months. Thereafter, the Company may need to raise additional funds.
The Company may need to raise additional funds sooner in order to fund more
rapid expansion, to develop new or enhanced services, to respond to competitive
pressures or to acquire complementary businesses or technologies. If additional
funds are raised through the issuance of equity securities, the percentage
ownership of the stockholders of the Company will be reduced, stockholders may
experience additional dilution, or such equity securities may have rights,
preferences or privileges senior to those
 
                                       16
<PAGE>   18
 
of the holders of the Company's Common Stock. There can be no assurance that
additional financing will be available when needed on terms favorable to the
Company or at all. If adequate funds are not available or are not available on
acceptable terms, the Company may be unable to develop or enhance its services,
take advantage of future opportunities or respond to competitive pressures,
which could have a material adverse effect on the Company's business, financial
condition or operating results. See "Dilution" and "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources."
 
DILUTION; ABSENCE OF DIVIDENDS
 
   
     The initial public offering price will be substantially higher than the
book value per share of Common Stock. Assuming an initial public offering price
of $13.00 per share, investors purchasing shares of Common Stock in this
offering will incur immediate, substantial dilution of $11.17 per share in the
net tangible book value of Common Stock. Additional dilution will occur upon the
exercise of outstanding options and warrants. See "Dilution." The Company has
never declared or paid any cash dividends and does not anticipate paying cash
dividends in the foreseeable future. The Company's loan and security agreement
and capital equipment leases prohibit the payment of dividends without the
consent of the respective lenders. See "Dividend Policy."
    
 
   
YEAR 2000 COMPLIANCE
    
 
   
     The Company uses a significant number of computer software programs and
operating systems in its internal operations. The use of computer programs that
rely on two-digit date programs to perform computations and decision-making
functions may cause computer systems to malfunction in the year 2000 and lead to
significant business delays and disruptions. While the Company believes that its
software applications are year 2000 compliant, to the extent that these software
applications contain source code that is unable to appropriately interpret the
upcoming calendar year 2000, some level of modification or possible replacement
of such source code or applications will be necessary. The Company is still
analyzing its software applications and, to the extent they are not fully year
2000 compliant, the costs necessary to update software or potential systems
interruptions may have a material adverse effect on the Company's business,
financial condition and results of operations. Furthermore, there can be no
assurance that the Company's suppliers and vendors are or will be year 2000
compliant. Failure of the Company's suppliers and vendors to achieve year 2000
compliance could have a material adverse effect on the Company's business,
financial condition and results of operations.

                                USE OF PROCEEDS
 
   
     The net proceeds to the Company from the sale of the shares of Common Stock
offered hereby are estimated to be $25.7 million ($30.1 million if the
underwriters' over-allotment option is exercised in full) at an assumed initial
public offering price of $13.00 per share after deducting underwriting discounts
and commissions and estimated offering expenses payable by the Company. The
Company will not receive any proceeds from the sale of Common Stock by the
Selling Stockholders.
    
 
   
     The Company intends to use approximately $5.2 million of the net proceeds
of the offering for the repayment of outstanding indebtedness, including $1.1
million to repay indebtedness to Hambrecht & Quist Guaranty Finance, LLC. See
"Underwriting." The balance of the net proceeds of the offering are expected to
be used for research and development activities, working capital and general
corporate purposes. These corporate purposes may include the purchase of
technology assets and licenses. The Company has no present understandings,
commitments or arrangements with respect to the purchase of any technology
assets or licenses, and the amount and timing of these expenditures will depend
on numerous factors, including the progress of the Company's research programs
and its ability to attract additional strategic partners. Pending application of
the net proceeds of the offering as described above, the Company intends to
invest such proceeds in short-term, investment-grade, interest-bearing financial
instruments.
    
 
     The Company anticipates that its existing resources, together with the net
proceeds of this offering, and projected interest income, will enable the
Company to maintain its current and planned operations through at least the next
12 months. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Liquidity and Capital Resources."
 
                                DIVIDEND POLICY
 
   
     The Company has never declared or paid any cash dividends on its capital
stock. The Company currently intends to retain any future earnings to finance
the growth and development of its business and therefore does not anticipate
paying any cash dividends in the foreseeable future. The Company's loan and
security agreement and capital equipment leases prohibit the payment of
dividends without the respective lenders' consent.

                                 CAPITALIZATION
 
   
     The following table sets forth as of December 31, 1997, (i) actual
capitalization of the Company as of December 31, 1997, (ii) the pro forma
capitalization of the Company giving effect to the conversion of all outstanding
shares of Preferred Stock into Common Stock and (iii) the pro forma
capitalization as adjusted to give effect to the receipt by the Company of the
estimated net proceeds from the sale of the 2,220,000 shares of Common Stock
offered hereby at an assumed initial public offering price of $13.00 per share,
after deduction of underwriting discounts and estimated offering expenses
payable by the Company, and the application of the estimated net proceeds
therefrom to repay borrowings outstanding as of December 31, 1997 of $3.2
million ($5.2 million as of March 31, 1998). This table should be read in
conjunction with "Management's Discussion and Analysis of Financial Condition
and Results of Operations" and the Consolidated Financial Statements and Notes
thereto included elsewhere in this Prospectus.

                                    DILUTION
 
   
     The pro forma net tangible book value of the Company as of December 31,
1997 was approximately $1,909,000, or $0.15 per share of Common Stock. Pro forma
net tangible book value per share is determined by dividing the net tangible
book value (tangible assets less total liabilities) of the Company by the number
of shares of Common Stock outstanding at that date, including shares of Common
Stock from the conversion of the Preferred Stock immediately prior to the
consummation of the offering. Without taking into account any other changes in
the net tangible book value after December 31, 1997, other than to give effect
to the receipt by the Company of the estimated net proceeds from the sale of
2,220,000 shares of Common Stock offered by the Company hereby at an assumed
initial public offering price of $13.00 per share (after deduction of
underwriting discounts and estimated offering expenses payable by the Company),
the pro forma net tangible book value of the Company as of December 31, 1997,
would have been $27.6 million, or $1.83 per share, respectively. This represents
an immediate increase in the pro forma net tangible book value of $1.68 per
share to existing stockholders and an immediate dilution of $11.17 per share to
new public investors. The following table illustrates this per share dilution:

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following Management's Discussion and Analysis of Financial Condition
and Results of Operations contains forward-looking statements that involve risks
and uncertainties. The Company's actual results could differ materially from
those anticipated in these forward-looking statements as a result of certain
factors, including those set forth under "Risk Factors" and elsewhere in this
Prospectus. The following discussion should be read in conjunction with the
Consolidated Financial Statements and Notes thereto included elsewhere in this
Prospectus.
 
OVERVIEW
 
     First Virtual provides a high quality, cost-effective video networking
solution that integrates video with voice and data, while leveraging existing
network infrastructures. The Company was incorporated in California in October
1993 and reincorporated in Delaware in December 1997. The Company first shipped
its video networking products in 1995.
 
   
     The Company has a limited operating history upon which an evaluation of the
Company and its prospects can be based. The Company has incurred net losses
since inception and, as of December 31, 1997, had an accumulated deficit of
$14.5 million. The Company has in the past, and may from time to time in the
future, experience quarterly fluctuations in revenues and operating results. The
Company adopted a strategy in the fourth quarter of 1996 to focus on a limited
number of substantial end-user projects, rather than on the implementation of a
large number of evaluation and demonstration projects. The initial impact of
this change of strategy was a decrease in revenues from $3.9 million in the
fourth quarter of 1996 to $2.7 million in the first quarter of 1997. The
Company's focus on a limited number of large end-user projects has resulted in,
and may in the future result in, significant fluctuations in quarterly revenues.
Furthermore, a significant portion of the Company's expenses are fixed in
advance. If revenues are below Company expectations in any given period, the
Company's inability to adjust operating expenses in response to such decreased
revenues would affect operating results.
    
 
     Gross margins are significantly influenced by a variety of factors,
including product mix, percentage of revenues derived from OEMs versus
distributors or resellers, pricing within the video networking industry and the
prices of significant components used in the Company's products. The Company
generally recognizes higher margins from video products and value added switch
modules and lower margins from base model V-Switches and adapter cards. The
Company's gross margins have fluctuated from period to period and are expected
to continue to do so in the future.
 
   
     The Company sells its products worldwide through OEM partners, distributors
and resellers. The Company established strategic relationships with Bay Networks
in November 1995 and Nortel in May 1997. In November 1995, the Company granted
Bay Networks the worldwide non-exclusive right to market and sell certain of the
Company's products. In September 1996, the Company granted Bay Networks the
worldwide non-exclusive right to market and sell all of the Company's current
and future products, under both the Company's and Bay Networks' names. In May
1997, the Company granted similar rights to Nortel to market the Company's
products under the Company's name. Sales through Bay Networks represented 29%
and 64% of the Company's revenues in 1996 and 1997, respectively. Sales by
Nortel have not been significant to date. The Company also plans to enter into
additional distribution agreements. See "Risk Factors -- Dependence on
Distribution Relationships."
    
 
     The Company recognizes revenues upon shipment of products to customers,
provided that no significant obligations remain and collectability is probable.
The OEM partners generally have no rights of return and have historically
carried limited amounts of inventories of the Company's products. Agreements
with certain distribution partners contain price protection provisions and
certain return rights. Accordingly, the Company records a provision for
estimated future returns and price protection upon revenue recognition. To date,
returns and charges for price protection have not been material.
                                       22
<PAGE>   24
 
   
     Direct sales from shipments to customers outside of North America accounted
for approximately 36.0% and 20.0% of the Company's revenues in 1996 and 1997,
respectively. The Company expects that direct sales from shipments to customers
outside of North America will continue to represent a significant portion of its
future revenues. In addition, the Company believes that a small portion of its
sales through Bay Networks and other distribution partners is sold to
international end-users. Revenues from the Company's international operations
are subject to various risks. To date, the Company has not engaged in any
foreign currency hedging activity. See "Risk Factors -- Risk of International
Sales and Currency Fluctuations."
    
 
     The Company outsources certain functions to independent service providers.
The Company's products are manufactured primarily by Tanon and accounting and
data processing functions are performed by KPMG.

     The following table sets forth certain items from the Company's

     YEARS ENDED DECEMBER 31, 1996 AND 1997
    
 
   
     Revenues. Revenues increased 55.2%, from $12.1 million in 1996 to $18.8
million in 1997. The increase in revenues resulted from wider acceptance of the
Company's products as a result of marketing efforts of the Company and its
strategic partners. Sales through Bay Networks increased 236.0%, from $3.5
million in 1996 to $11.9 million in 1997.
    
 
     Gross Profit. Gross profit consists of revenues less the cost of revenues,
which consists primarily of costs associated with the manufacture of the
Company's products by Tanon and other manufacturers and related costs of
freight, inventory obsolescence, royalty and warranty. These manufacturers
procure the majority of materials, except for certain key components which the
Company purchases from third party vendors.
 
   
     Gross profit increased 49.7%, from $5.5 million in 1996 to $8.3 million in
1997. Gross margin (gross profit as a percentage of revenues) remained
relatively constant, decreasing from 45.9% in 1996 to 44.2% in 1997.
    
 
   
     Research and Development. Research and development expenses consist
primarily of personnel costs, cost of contracts and outside consultants,
supplies and material expenses, equipment depreciation and overhead costs.
Research and development expenses increased 85.0%, from $2.9 million in 1996 to
$5.4 million in 1997. The increase was the result of hiring additional engineers
and consultants for product development and non-cash compensation charges
relating to the Company's employee stock plans, which
    
 
                                       23
<PAGE>   25
 
   
increased from $174,000 in 1996 to $506,000 in 1997. The Company believes that
research and development expenses will continue to increase for the foreseeable
future. However, such expenses will fluctuate depending on various factors,
including the status of development projects.
    
 
   
     Selling, General and Administrative. Selling, general and administrative
expenses include personnel and related overhead costs for sales, marketing,
finance, human resources and general management. Such expenses also include
costs of outside contractors, advertising, trade shows and other marketing and
promotional expenses. Selling, general and administrative expenses increased
43.2%, from $4.9 million in 1996 to $7.0 million in 1997. As a percentage of
total revenues, selling, general and administrative expenses decreased from
40.4% in 1996 to 37.2% in 1997. The increase in absolute dollars was the result
of expanding the Company's sales and marketing infrastructure, in addition to
higher marketing and selling costs and to non-cash compensation charges relating
to the Company's employee stock plans, which increased from $165,000 in 1996 to
$631,000 in 1997. The decrease as a percentage of revenues was due to the
increase in revenues in 1997. The Company anticipates that selling, general and
administrative expenses will continue to increase in absolute dollars in the
foreseeable future as the Company expands its selling and marketing efforts and
incurs the administrative costs associated with being a publicly-held company.
    
 
   
     Income Taxes. As of December 31, 1997, the Company had net operating loss
carryforwards for federal tax purposes of approximately $13.0 million. These
carryforwards, if not utilized to offset future taxable income, will expire at
various dates beginning in 2008. Under the ownership change limitations provided
by the Internal Revenue Code of 1986, as amended, the amount of and benefit from
the net operating losses that can be carried forward may be impaired or limited
in certain circumstances. See Note 5 of Notes to Consolidated Financial
Statements. As of December 31, 1997, the Company had gross deferred tax assets
of approximately $5.8 million. The Company has incurred losses since inception.
The Company believes that, based on the history of such losses and other
factors, the weight of available evidence indicates that it is more likely than
not that it will not be able to realize its deferred tax assets, and thus a full
valuation reserve has been recorded as of December 31, 1997.
    
 
   
     YEARS ENDED DECEMBER 31, 1995 AND 1996
    
 
   
     Revenues. The Company's revenues increased from $3.7 million in 1995 to
$12.1 million in 1996. The increase primarily resulted from development of the
market for, and increased acceptance of, the Company's products.
    
 
     Gross Profit. Gross profit increased from $796,000 in 1995 to $5.5 million
in 1996. Gross margin increased from 21.7% in 1995 to 45.9% in 1996. The
increase in gross profit and gross margin resulted from cost reductions
associated with higher volume of product shipments. Additionally, gross profit
and gross margin in 1995 were adversely affected by higher costs associated with
initial production runs of the Company's products.
 
   
     Research and Development. Research and development expenses increased from
$2.6 million in 1995 to $2.9 million in 1996. The increases in research and
development expenses were primarily a result of increased headcount and
associated expenses incurred to develop, expand and enhance the Company's
products. Research and development expenses for 1996 also include non-cash
compensation charges relating to the Company's employee stock plans of $174,000.
    
 
   
     Selling, General and Administrative. Selling, general and administrative
expenses increased from $3.6 million in 1995 to $4.9 million in 1996. The
increases in selling, general and administrative expenses were primarily due to
an increase in headcount, and in marketing, advertising, travel and related
overhead costs incurred by the Company to manage and support its efforts to
develop the market for its products and support its growth. Selling, general and
administrative expenses for 1996 also include non-cash compensation charges
relating to the Company's employee stock plans of $165,000.

     Income Taxes. No provision for income taxes has been recorded, as the
Company has incurred losses since inception.
 
QUARTERLY RESULTS
 
   
     The following table sets forth selected unaudited consolidated statement of

     Revenues increased during each of the first three quarters in 1996 due to
increased shipments of the Company's products. The Company's quarterly revenues
are affected by the size and timing of orders received by customers. During the
fourth quarter of 1996, the Company adopted a strategy of focusing on a limited
number of substantial end-user projects, rather than on sales of a large number
of demonstration projects. The initial impact of the change of strategy was a
decrease in revenues from $3.9 million in the quarter ended December 31, 1996 to
$2.7 million in the quarter ended March 31, 1997. Revenues increased during each
of the quarters in 1997, due primarily to higher revenues from large end-user
projects sold through Bay Networks in the OEM channel. Gross margins ranged from
39.7% to 53.4% during the periods presented, due primarily to product mix and
mix of sales through OEM versus distributors. In particular, during the quarter
ended December 31, 1996, the gross margin increased as a result of sales to
end-users of high margin products. During the quarter ended September 30, 1997,
gross margins were adversely impacted by a higher concentration of OEM sales and
the timing of shipments of certain lower margin products. During the quarter
ended December 31, 1997, gross margins improved primarily due to shipments of
certain higher margin products. Operating expenses generally increased during
the periods presented due to costs associated with increased headcount and
marketing and selling expenses incurred by the Company.
    
 
     The Company has in the past experienced, and believes that it may from time
to time experience, fluctuations in revenues and operating results from quarter
to quarter due to a combination of factors, many of which are outside of the
Company's control. See "Risk Factors -- Fluctuations in Operating Results."
 
STOCK BASED COMPENSATION
 
   
     With respect to certain stock options and restricted stock grants made
during 1996 and 1997, the Company is recognizing compensation charges of $2.1
million. The Company recognized $339,000 and $1.1 million of the compensation
charges in 1996 and 1997, respectively, and will recognize the remainder over
the related vesting period. The future compensation charges are subject to
reduction for any employee who terminates employment prior to the expiration of
such employee's vesting period. See Note 8 of Notes to Consolidated Financial
Statements.
    
 
   
YEAR 2000 COMPLIANCE
    
 
   
     The widespread use of computer programs that rely on two-digit date
programs to perform computations and decision-making functions may cause
computer systems to malfunction in the year 2000 and lead to significant
business delays and disruptions. First Virtual has addressed the issue of year
2000 compliance in both its internal information systems and its products. The
Company also has made inquiries regarding the year 2000 issue of its suppliers
and vendors. Based upon such inquiries, the Company does not believe year 2000
compliance issues will have a material adverse impact upon its business.
However, failure of the Company's suppliers and vendors to achieve year 2000
compliance could have a material adverse effect on the Company's business,
financial condition and results of operations.
    
 
LIQUIDITY AND CAPITAL RESOURCES
 
   
     Since inception through December 31, 1997, the Company has financed its
operations primarily through private placements of equity securities, raising an
aggregate of approximately $14.8 million, net of issuance costs. As of December
31, 1997, the Company had cash and cash equivalents of $2.5 million and working
capital of $1.9 million.
    
 
   
     The Company has used cash in its operating activities primarily to fund
losses of $14.5 million incurred through December 31, 1997, and to finance its
working capital needs.
    
 
   
     The Company has not made significant outlays for capital expenditures since
inception because of its strategy to outsource manufacturing and certain other
functions. From inception through December 31, 1997, the Company's capital
expenditures aggregated $1.4 million and have consisted primarily of purchases
of computers, related equipment, furniture and fixtures.
    
 
                                       26
<PAGE>   28
 
   
     The Company has a working capital line of credit with a bank which provides
for borrowings of up to $3.0 million. Borrowings under the line of credit bear
interest at the bank's prime rate (8.5% at December 31, 1997) plus 0.75%, are
secured by certain assets of the Company and are limited to certain percentages
of the Company's accounts receivable and inventory balances. As of December 31,
1997, borrowings under this line aggregated $1.3 million ($2.2 million as of
March 31, 1998) and an additional approximately $500,000 was available to the
Company. The line expires in April 1998, and requires the Company to comply with
certain financial ratios and covenants and limits the Company's ability to pay
dividends. As of December 31, 1997, the Company was not in compliance with
certain financial covenants contained in the line of credit agreement. The bank
waived the Company's noncompliance with these covenants as of December 31, 1997.
    
 
   
     In February 1998, the Company agreed in principle to enter into a
transaction with Hambrecht & Quist Guaranty Finance, LLC ("Guaranty Finance"),
whereby Guaranty Finance would loan the Company up to $5 million. Under the
related agreements which were executed on March 12, 1998, (i) Guaranty Finance
agreed to lend the Company up to $5 million at an interest rate of 12% per
annum, $1.1 million of which was loaned to the Company on March 13, 1998 (the
"Loan") and (ii) Guaranty Finance purchased from the Company for $1,250 a
warrant to purchase 125,000 shares of the Company's Common Stock at a purchase
price of $8.00 per share. The Company has an option to repurchase up to 62,500
shares dependent on the level of borrowings over the term of the financing
arrangement. The warrant is exercisable through March 1, 2003. The Company paid
a $100,000 fee to Guaranty Finance in consideration for entering into the
aforementioned loan transaction.
    
 
   
     The Company anticipates that $5.2 million of the net proceeds of this
offering will be used to pay its outstanding indebtedness, including $2.2
million for borrowings under the working capital line of credit and $1.1 million
for the outstanding balance of the Loan.
    
 
     The Company believes that the net proceeds from this offering, together
with existing sources of liquidity, will provide adequate cash to fund its
operations for at least the next twelve months. Thereafter, if cash generated by
operations is insufficient to satisfy the Company's liquidity requirements, the
Company may be required to sell additional equity or debt securities or increase
its lines of credit. The sale of additional equity or convertible debt
securities may result in additional dilution to the Company's stockholders.

OVERVIEW
 
   
     First Virtual Corporation provides a high quality, cost-effective Internet
video networking solution for the Next Generation Internet that integrates video
with voice and data, while leveraging existing network infrastructures. The
Company combines its expertise in real-time network systems and video technology
to extend the capabilities of QoS across existing network architectures,
including IP, ATM and Ethernet. A network based on an architecture that supports
QoS can simultaneously carry multiple video streams, as well as voice and data.
First Virtual's broad product line enables it to deliver end-to-end solutions
for a wide range of NGI applications, such as distance learning, telemedicine,
video marketing and video manufacturing. A critical element of the Company's
technology is its MOS software, designed to guarantee network resources for
real-time video applications in the presence of voice and bursts of data packets
on any network capable of supporting QoS. The Company's high quality,
easy-to-use video networking systems are scaleable to multiple locations and
thousands of users. First Virtual's solution addresses its customers'
requirement for high quality interactive visual communications through a broad
range of Internet video server and video access products.
    
 
   
     The Internet was originally designed to support delay-tolerant data
transmission applications such as electronic mail. Until recently, the limited
bandwidth and QoS capabilities of this "first generation" Internet did not
support the implementation of interactive visual applications. The enhanced
communication enabled by interactive visual applications such as Internet video
networking can provide significant benefits in a broad range of environments.
These include distance learning, telemedicine, video marketing and video
manufacturing. As a result, the need for a "next generation" Internet to enable
end users at remote locations to learn and work across networks -- interactively
and in real time -- is becoming widely accepted. In response, network managers
have begun to implement Internet and Intranet networks with the considerably
greater bandwidth and support for QoS required to enable Internet video
networking applications. The Company collectively defines these implementations
of advanced networking infrastructures as the NGI. Current NGI implementations
include statewide ATM networks, campus and enterprise ATM backbones and ATM WANs
using T1, DS3 and OC3 links.
    
 
   
     The Company has global OEM relationships with Bay Networks and Nortel and
has established relationships with a number of VARs and systems integrators,
including BANI, BT, Clover Communications, Inc., France Telecom, IBM Global
Services, NEC Corporation and NTT. The Company has also built a network of
international distributors to sell, service and support its products in more
than 40 countries worldwide. The Company's solutions have been deployed by a
broad range of educational institutions, corporations and government agencies,
such as Virginia Tech (distance learning facilities); IBM (headquarters facility
in Armonk, New York); Peregrine Incorporated (headquarters and multiple
manufacturing facilities); and Shanghai Infoport (government metropolitan
network). In addition, the Company has recently licensed technology from IBM to
facilitate broadcast quality Internet video over the NGI.
    
 
   
INDUSTRY BACKGROUND
    
 
   
     In recent years, deployment of the communications infrastructure that
constitutes the Internet has evolved to meet the requirements of new and
emerging Internet applications. The Internet was originally designed to support
delay-tolerant data transmission applications such as electronic mail. Until
recently, the limited bandwidth and QoS capabilities of this "first generation"
Internet did not support the delivery of applications such as interactive visual
communications. Specifically, because the technologies employed by first
generation Internet infrastructure were unable to differentiate between bursty
data transmissions and broadcast video streams, the first generation Internet
could not support high quality video networking applications. This situation
limited the deployment and use of interactive applications that allow end users
to simultaneously utilize high quality video and data applications.
    
 
   
     The need for a "next generation" Internet to enable end users at remote
locations to work and learn across the network -- interactively and in real
time -- is becoming widely accepted. The
    
 
                                       28
<PAGE>   30
 
   
enhanced communication enabled by high quality video networking can provide
significant benefits in a broad range of environments. All levels of educational
institutions can utilize distance learning facilities to enable experts to teach
in any classroom. Businesses can hold high quality, face-to-face meetings
without time consuming travel. Sales professionals can deliver presentations to
prospective customers in many cities in a single day. Hospitals can deploy
telemedicine to enable a team of doctors in different locations to diagnose and
treat patients remotely. Manufacturing companies can achieve efficiencies by
offering real-time instruction and support for workers on the factory floor.
    
 
   
     Network managers have responded to the need to implement these types of
applications by deploying Intranet and Internet networks with considerably
greater support for bandwidth and QoS. Additional bandwidth permits greater
application scaleability and QoS provides the predictable latency essential for
quality Internet video. Bell Atlantic, driven by demands for multi-service
networks, incorporated voice, data and video capabilities into its core network
infrastructure. Similarly, the Federal Government has provided funding since
early 1997 for the deployment of a next generation Internet for applications
such as distance learning. Additionally, Internet2, an Internet Engineering Task
Force initiative, has provided new ways to implement QoS in an Internet Protocol
("IP") environment. Further, corporations are implementing high bandwidth
QoS-capable, video-enabled Intranets for learning and working in real time
across their networks. Together, these implementations of advanced networking
initiatives comprise what the Company defines as the NGI.
    
 
   
     The initial NGI networks are being deployed as statewide ATM networks.
ATM-based transport for WANs allows implementation of high bandwidth networks
based on architectures that support QoS, simultaneous multiple video streams,
voice and data. Local area networks ("LANs") are typically based on Ethernet
running the IP protocol and provide a means of connecting end-user equipment
onto the NGI.
    
 
   
     To achieve broad market acceptance, a video networking solution for the NGI
must offer high quality interactive video and access to live and stored video
while seamlessly integrating voice and data traffic. An effective video
networking solution must also be scaleable, easy to use, cost-effective, and
leverage an organization's existing investment in video equipment and in other
network infrastructures, including the ability to extend ATM QoS characteristics
to Ethernet and IP networks.

  A Case Study: Video in Distance Learning
 
   
     First Virtual recently sold a multi-site video network that enabled a major
university in the eastern United States to implement a "virtual classroom"
environment across a statewide ATM-based NGI network. The university had
experienced rapidly escalating communications costs due to the increasing use of
data, voice and video applications over a separate network for each type of
traffic. The move to an NGI network, made available by the university's local
carriers, enabled the university to deploy all applications on an integrated
network at a much lower cost. The university purchased video networking
equipment from the Company, including V-Switches, V-Rooms and V-NICs, as well as
T1 WAN equipment, at aggregate revenues to First Virtual of approximately
$220,000. The Company's products are being used to create a virtual classroom
environment that links all parts of the statewide campus, enabling delivery of
live lectures to students across an ATM network. First Virtual's equipment
enables VTEL interactive video equipment to operate at high data rates,
providing very high quality video transmission. Additionally, the university is
currently investing in the Company's V-Caster product to enable lectures to be
stored and replayed across the network.
    
 
  A Case Study: Video in Manufacturing
 
   
     A major United States auto parts manufacturer recently implemented a
multi-location, 1000-plus user video network to enable it to move faster than
its global competitors. The manufacturer implemented an extensive video network
based on the Company's V-Switch and V-NIC products, at aggregate revenues to
First Virtual of approximately $700,000. The auto parts manufacturing business
has experienced great pressure on its product cycle times, which have moved from
years to months in the last decade. The manufacturer implemented an extensive
ATM network based on the Company's V-Switch ATM infrastructure products to allow
simultaneous delivery of video and data. The Chief Executive Officer and other
executives of this company use First Virtual's video networking products to
collaborate face-to-face and make business decisions in real time. This end-user
implemented an NGI infrastructure to allow video and data to be carried
simultaneously on the network without slowing data transfer or compromising
video quality. This customer is currently investing in First Virtual's V-Cache
products to enable its executives to make more compelling presentations and to
implement factory floor learning.
    
 
MARKETING, SALES AND CUSTOMER SUPPORT
 
   
     First Virtual markets its products to business customers, government users
and educational providers through its internal sales force and indirect sales
channels. The Company's internal sales force uses the Company's video technology
to directly qualify and stimulate end-user demand, as well as to manage the
Company's strategic relationships with its OEMs, VARs and systems integrators. A
large portion of the Company's sales to date have been fulfilled through the
Company's OEMs, including Bay Networks. Sales through Bay Networks represented
approximately 29% of the Company's total sales in 1996 and 64% in 1997. These
OEMs in turn work with leading systems integrators to install the Company's
products. Systems integrators qualified to install First Virtual's products
include BANI, BT, Clover Communications, Inc., EDS, France Telecom, GTE
Corporation, NTT, IBM Global Services, Inc. and NEC Corporation.
    
 
     The Company has a formal training program in place to train its OEMs' and
resellers' sales personnel. This program focuses on developing their ability to
feature First Virtual's video products as a key part of a differentiated
offering. First Virtual also highlights the potential for its OEMs and resellers
to use the Company's product to seed sales of the OEMs' and resellers'
respective core networking products.
 
   
     In addition to its global OEM relationships with Bay Networks and Nortel,
the Company maintains a network of distributors in Europe and Asia licensed to
sell its products under the First Virtual name. The Company's international
distributors are known as First Virtual France, operated by Tekelec Airtronic
GmbH; and First Virtual Asia, Korea and the United Kingdom, operated by private
    
 
                                       36

companies. In the years ended December 31, 1996 and 1997, approximately 36% and
20%, respectively, of the Company's sales were generated from customers outside
of North America.
    
 
     First Virtual provides service and support to its customers through its
OEMs, distributors and resellers in more than 40 countries worldwide. The
Company employs a support model that trains its business partners to enable them
to identify and resolve basic problems (level one and level two support). The
Company provides level three technical support to its OEMs and VARs.
 
   
     First Virtual's service strategy for a majority of its product line is
predicated on designing products with extensive diagnostic capabilities. These
remote diagnostic capabilities often allow the Company's Technical Support
Center personnel to cost-effectively service its products without requiring
on-site service visits. First Virtual generally warrants its products to be free
of defects in materials and workmanship for periods ranging from three to 36
months from date of shipment. To date, warranty expense and product returns have
not been material.
    
 
RESEARCH AND DEVELOPMENT
 
   
     Since its inception, First Virtual has recognized that a strong technical
base is essential to its long-term success and has made a substantial investment
in research and development. To date, the Company has aggressively brought a
wide range of products into the marketplace. First Virtual intends to make
substantial investments in product development and to participate in the
development of industry standards. The Company monitors changing customer needs
and works closely with its OEM partners, end-user customers and market research
organizations to track changes in the marketplace, including emerging industry
standards in both networking and video. The Company intends to maintain its
focus on broadening its product line to include emerging video technologies,
such as MPEG-II at the high end and IP video at the low end. As part of this
strategy, First Virtual's near term development efforts include commercial
introduction of the V-Gate323 and First Virtual's V-Locator products.
    
 
   
     The Company's research and development expenditures totaled $2.6 million,
$2.9 million and $5.4 million for the years ended December 31, 1995, 1996 and
1997, respectively. As of March 31, 1998, 35 full-time employees were engaged in
research and product development. First Virtual performs its research and
product development activities at its headquarters. The Company also hires
engineers located in India on a contract basis from time to time. First Virtual
is seeking to hire additional skilled development engineers, which are currently
in short supply. The Company's business, operating results and financial
condition could be adversely affected it if encounters delays in hiring required
engineers.
    
 
COMPETITION
 
     The video networking industry is becoming increasingly competitive. First
Virtual believes that its principal competitive advantage in the video
networking market is the Company's ability to provide easy to use,
cost-effective, high quality video networking solutions that integrate video
with voice and data, while leveraging existing network infrastructures. Working
at the intersection of the video and networking markets provides First Virtual
with the potential to establish strategic relationships with a wide range of
companies. However, this also results in competition from many companies in
certain segments of the video networking area.
 
   
     As an end-to-end high quality ATM-based video networking solution, First
Virtual's products face actual and potential competition in different market
segments. The Company's most direct competitors also currently offer video
networking over ATM, including FORE and Newbridge. The Company's video
networking products also compete with systems based on other technologies, such
as the ISDN-based video networking products offered by Madge. First Virtual's
video access products, when sold by its distribution partners such as Bay
Networks, are used to compete with ATM-based infrastructure products sold by
companies such as Cisco and 3Com. In the interactive video area, the Company's
technology licensing agreement with IBM is intended to result in products which
may compete with
    
                                       37
<PAGE>   39
 
   
products sold by companies such as Newbridge in the high-end H.310 interactive
video market. In video storage, the Company's V-Cache products face competition
from companies which offer high-performance servers that can store video, such
as SGI, Starlight, Sun and TNC. In the video broadcast area, First Virtual's
products also compete with systems and software products of companies which
provide "streamed" video over IP/Ethernet networks, such as Optivision and
Precept Software. The Company faces potential competition from large companies
which have products in related areas, such as Microsoft and Intel. The Company
could encounter new competition if companies which distribute First Virtual's
products, or whose interactive video equipment are used together with the
Company's products, develop or acquire video networking technologies or
products. There can be no assurance that the Company will be able to compete
successfully in this environment.
    
 
     Many of the Company's actual and potential competitors have greater name
recognition; a larger installed base of networking products and strong
relationships with end users; more extensive engineering, manufacturing,
marketing and distribution capabilities; and greater financial, technological
and personnel resources than First Virtual. The networking industry is
undergoing a period of consolidation in which companies, including some of the
Company's competitors, are participating in business combinations, creating
competitors with larger market shares, customer bases, sales forces, product
offerings and technology and marketing expertise.
 
     The Company's principal method of competition is product performance. To
compete effectively, First Virtual must continue to offer an end-to-end
solution, provide high-performance products which comply with applicable
standards and are easy to use, and expand its product distribution channels
domestically and internationally. There can be no assurance that the Company
will be able to compete effectively on these bases.
 
     In addition, the Company expects price competition to escalate in the video
networking industry. Although First Virtual has rarely lowered product prices in
the past, anticipated competition may force it in the future to lower product
prices on a regular basis and add new products and features without increasing
prices. There can be no assurance that the Company will be able to compete
successfully in such a price competitive environment. If such pricing pressures
are not mitigated by cost reduction or changes in product mix, the Company's
business, financial condition and results of operations would be materially
adversely affected. See "Risk Factors -- Competition; Industry Consolidation."
 
MANUFACTURING
 
   
     First Virtual uses third-party manufacturers to perform materials planning,
production scheduling, mechanical assembly, board testing, system integration,
burn-in and final system testing of its products. The Company currently
outsources manufacturing to Tanon, Empac and PCB as turnkey manufacturers of
certain of its products. The Company's operations staff develops manufacturing
strategies and qualifies manufacturing processes and suppliers. First Virtual
and its contract manufacturers work together to reduce manufacturing costs and
to resolve quality control issues. The manufacturer ships the products directly
to the customer, without any further testing by the Company. First Virtual's
contract manufacturers are IS0 9002 qualified. The Company's manufacturing
strategy enables it to leverage the manufacturing capabilities of its
third-party manufacturers, while allowing the Company to focus on its core
competencies of rapid product development and deployment. If one or more of
First Virtual's manufacturers experiences quality or other problems, product
shipments by the Company may be delayed. The Company has experienced such delays
in the past and may in the future experience delays. If the Company is required
to find replacements for its manufacturers, such change in manufacturers could
result in short-term cost increases and delays in delivery, which could have a
material adverse effect on the Company's business, financial condition and
results of operations. First Virtual maintains a safety stock of critical
components and reserve inventory, which would not be sufficient to meet
increases in demand occurring simultaneously with delayed deliveries from
manufacturers. There can be no assurance that the Company will be able to
negotiate acceptable arrangements with its existing or any future manufacturers,
or, if negotiated, that such arrangements
    
 
                                       38
<PAGE>   40
 
will be on terms favorable to the Company. See "Risk Factors -- Dependence on
Third Parties for Manufacturing."
 
INTELLECTUAL PROPERTY
 
   
     First Virtual believes that its future success depends primarily upon its
ability to rapidly bring new products to market to enable it to remain at the
forefront of high quality video networking. The Company's success and ability to
compete in the networking industry also depends, in part, upon its ability to
protect its proprietary technology and operate without infringing the
proprietary rights of others.
    
 
     The Company does not rely on patent protection for, and does not hold any
patents relating to, its products. In addition, First Virtual's adherence to
industry-wide technical standards and specifications may limit its opportunities
to provide proprietary product features capable of protection. The Company
currently relies upon a combination of trade secret, copyright and trademark
laws and contractual restrictions to establish and protect proprietary rights in
its products. First Virtual also enters into confidentiality and invention
assignment agreements with its employees and enters into non-disclosure
agreements with its suppliers, distributors and customers to limit access to and
disclosure of its proprietary information. There can be no assurance that these
statutory and contractual arrangements will be sufficient to deter
misappropriation of the Company's proprietary technologies or that independent
third-parties will not develop similar or superior technologies. The development
of alternative technologies by third parties could adversely affect the
competitiveness of the Company's products. In addition, the laws of some
countries do not provide the same degree of protection of First Virtual's
proprietary information as do the laws of the United States.
 
     The commercial success of First Virtual will also depend, in part, on its
ability to obtain licenses to third-party technology and on its not breaching
its existing and future licenses of third-party technology used in certain of
First Virtual's products. The Company entered into a license agreement for
certain technology with Advanced Telecommunications Modules Limited ("ATML") in
February 1994. The agreement provides First Virtual with a perpetual
non-exclusive license to certain ATML technology. The agreement can be
terminated by either party upon 60 days notice for material breach. In addition,
the Company entered into a non-exclusive technology license agreement with IBM
in October 1997 for IBM's VAN technology. The Company plans to integrate this
technology into its video networking systems. This agreement may be terminated
by IBM for material breach by First Virtual. In addition, IBM has the right to
acquire any First Virtual intellectual property based on the licensed technology
under certain circumstances, including a material breach by the Company.
 
     The Company is also subject to the risk of litigation alleging infringement
of third party intellectual property rights. A number of companies have
developed technologies or received patents on technologies that may be related
to or be competitive with First Virtual's technologies. The Company has not
conducted a patent search relating to the technology used in its products. In
addition, since patent applications in the United States are not publicly
disclosed until the patent issues, applications may have been filed which, if
issued as patents, would relate to the Company's products. Many of these
companies have significantly greater resources than the Company. Given the rapid
development of technology in the video networking industry, there can be no
assurance that First Virtual's existing or future products will not infringe
upon the existing or future proprietary rights of others. Further, the Company's
lack of patents may inhibit its ability to negotiate cross-licenses or oppose
patents of third parties, if necessary. The Company could incur substantial
costs in defending itself and its customers against any such claims, regardless
of the merits of such claims. The Company may be required by contract or by
statutory implied warranties to indemnify its distribution partners and
end-users against third-party infringement claims. Parties making such claims
may be able to obtain injunctive or other equitable relief which could
effectively block the Company's ability to sell its products in the United
States and abroad, and could result in an award of substantial damages. In the
event of a successful claim of infringement, the Company, its customers and
end-users may be required to obtain one or more licenses from third parties.
There can be no assurance that the
                                       39
<PAGE>   41
 
Company or its customers could obtain necessary licenses from third parties at a
reasonable cost, or at all. The defense of any lawsuit could result in
time-consuming and expensive litigation, damages, license fees, royalty payments
and restrictions on the Company's ability to sell its products, any of which

BOARD COMPOSITION
 
     The Company currently has authorized six directors. In accordance with the
terms of the Company's Certificate of Incorporation, effective upon the closing
of this offering, the terms of office of the Board of Directors will be divided
into three classes: Class I, whose term will expire at the annual meeting of
stockholders to be held in 1998; Class II, whose term will expire at the annual
meeting of stockholders to be held in 1999; and Class III, whose term will
expire at the annual meeting of stockholders to be held in 2000. The Class I
directors are Mr. Torresi and Mr. Falotti, the Class II directors are Mr. Norman
and Mr. Douglas, and the Class III directors are Mr. Ungermann and Mr. Swartz.
At each annual meeting of stockholders after the initial classification, the
successors to directors whose term will then expire will be elected to serve
from the time of election and
                                       42
<PAGE>   44
 
qualification until the third annual meeting following election. In addition,
the Company's Certificate of Incorporation provides that the authorized number
of directors may be changed only by resolution of the Board of Directors. Any
additional directorships resulting from an increase in the number of directors
will be distributed among the three classes so that, as nearly as possible, each
class will consist of one-third of the directors. This classification of the
Board of Directors may have the effect of delaying or preventing changes in
control or management of the Company. Although directors of the Company may be
removed for cause by the affirmative vote of the holders of a majority of the
Common Stock, the Company's Certificate of Incorporation provides that holders
of two-thirds of the Common Stock must vote to approve the removal of a director
without cause. There are no family relationships among any of the directors and
executive officers of the Company.
 
BOARD COMMITTEES
 
   
     The Audit Committee of the Board of Directors, currently consisting of
Messrs. Douglas and Norman, reviews the internal accounting procedures of the
Company and consults with and reviews the services provided by the Company's
independent accountants. The Compensation Committee of the Board of Directors,
currently consisting of Messrs. Swartz and Torresi, reviews and recommends to
the Board of Directors the compensation and benefits of all officers of the
Company and reviews general policies relating to compensation and benefits of
employees of the Company.
    
 
DIRECTOR COMPENSATION
 
     The Company does not currently compensate directors for services in such
capacity, but directors may be reimbursed for certain expenses in connection
with attendance at Board and Committee meetings. The Company may compensate
non-employee directors in the future.
 
   
     All of the Company's non-employee directors are entitled to receive
non-discretionary annual stock option grants under the Company's 1997
Non-Employee Directors' Stock Option Plan (the "Directors' Plan"), adopted in
September 1997 (the "Effective Date"). Under the Directors' Plan, each current
non-employee director was automatically granted an option to purchase 10,000
shares of Common Stock upon the Effective Date. Messrs. Torresi, Douglas,
Swartz, Norman and Falotti were each granted an option to purchase 10,000 shares
of the Company's Common Stock at an exercise price of $11.00 per share. Each new
non-employee director who is subsequently elected for the first time will
automatically be granted an option to purchase 30,000 shares of Common Stock at
the time he or she is first elected to the Board of Directors. Each non-employee
director will additionally be granted an option to purchase 10,000 shares of
Common Stock on each anniversary of each such director's original grant under
the Directors' Plan. Options granted under the Directors' Plan are granted at
the fair market value of the Common Stock on the date of grant. Options granted
to non-employee directors under the Directors' Plan have a 10-year term and will
vest over a period of five years, with 10% of the shares vesting after six
months and the remaining shares vesting ratably on a daily basis thereafter. See
"Stock Plans -- 1997 Non-Employee Directors' Stock Option Plan."

(1) 10% of the options generally become exercisable six months after the vesting
    commencement date and .0548% each day thereafter for 54 months. The term of
    each option granted is generally the earlier of (i) ten years or (ii) 30
    days after termination of the holder.
 
   
(2) Based on an aggregate of 1,285,144 options granted to employees, consultants
    and directors, including the Named Executive Officers, of the Company during
    the fiscal year ended December 31, 1997 (includes 499,500 options which were
    cancelled and replaced with lower-priced options in February 1998).
    
 
   
(3) The exercise price per share of each option was equal to the fair market
    value of the Common Stock on the date of grant as determined by the Board of
    Directors.
    
 
   
(4) The 5% and 10% assumed annual rates of compounded stock price appreciation
    are mandated by rules of the Securities and Exchange Commission. There can
    be no assurance provided to any executive officer or any other holder of the
    Company's securities that the actual stock price appreciation over the
    option term will be at the assumed 5% or 10% levels or at any other defined
    level. Unless the market price of the Common Stock appreciates over the
    option term, no value will be realized from the option grants made to the
    executive officers. The potential realizable value is calculated by assuming
    that the assumed initial public offering price of $13.00 per share
    appreciates at the indicated rate for the entire term of the option and that
    the option is exercised at the exercise price and sold on the last day of
    its term at the appreciated price. The potential realizable value
    computation is net of the applicable exercise price, but does not take into
    account applicable federal or state income tax consequences and other
    expenses of option exercises or sales of appreciated stock. Messrs.
    Mitchell's, Sequeira's, McMillan's and Nielsen's options each have ten-year
    terms.

STOCK PLANS
 
   
     1997 Equity Incentive Plan. The Company's 1997 Equity Incentive Plan (the
"Incentive Plan"), to be effective upon the closing of the offering, was adopted
by the Board of Directors in October 1997 as an amendment and restatement of the
Company's 1996 Stock Option Plan, 1996 Stock Option Plan No. 2 (collectively,
the "1996 Plans") and the Company's 1993 Employee, Consultant and Director Stock
Purchase Plan (the "1993 Plan"). Except with respect to then outstanding stock
purchase grants and options, the 1996 Plans and the 1993 Plan, in their
respective current forms, will terminate upon the effectiveness of the Incentive
Plan. Upon effectiveness of the offering, no further grants will be made under
the 1996 Plans as currently in effect. Future stock and option grants to
employees, directors and consultants will be made under the successor Incentive
Plan. Outstanding options and grants under the 1996 Plans will continue to be
governed by their existing terms, which generally contain substantially the same
terms and conditions as those described below for the Incentive Plan. As of
March 31, 1998, the total number of authorized shares under the Incentive Plan
is 4,625,000 shares of Common Stock, of which approximately 1,178,466 shares
will be available for grant under the Incentive Plan upon its effectiveness.
    
 
     The Incentive Plan provides for the grant of incentive stock options under
the Internal Revenue Code of 1986, as amended (the "Code"), to employees
(including officers and employee-directors) and nonstatutory stock options,
restricted stock purchase awards and stock bonuses to employees, directors and
consultants. The Incentive Plan is administered by the Board of Directors or a
committee appointed by the Board, which determines recipients and types of
awards to be granted, including the exercise price, number of shares subject to
the award and the exercisability thereof.
 
     The terms of stock options granted under the Incentive Plan generally may
not exceed 10 years. The exercise price of options granted under the Incentive
Plan is determined by the Board of Directors, provided that the exercise price
for an incentive stock option cannot be less than 100% of the fair market value
of the Common Stock on the date of the option grant and the exercise price for a
nonstatutory stock option cannot be less than 85% of the fair market value of
the Common Stock on the date of option grant. Options granted under the
Incentive Plan vest at the rate specified in the option agreement. No stock
option may be transferred by the optionee other than by will or the laws of
descent or distribution, provided that a nonstatutory stock option may be
transferable if provided in the option agreement, and provided further that an
optionee may designate a beneficiary who may exercise the option following the
optionee's death. An optionee whose relationship with the Company or any related
corporation ceases for any reason (other than by death or permanent and total
disability) may exercise options in the 30-day period following such cessation
(unless such options terminate or expire sooner or later by their terms).
Options may be exercised for up to twelve months after an optionee's
relationship with the Company and its affiliates ceases due to disability and up
to
 
                                       46
<PAGE>   48
 
eighteen months after an optionee's relationship with the Company and its
affiliates ceases due to death (unless such options expire sooner or later by
their terms).
 
     No incentive stock option may be granted to any person who, at the time of
the grant, owns (or is deemed to own) stock possessing more than 10% of the
total combined voting power of the Company or any affiliate of the Company,
unless the option exercise price is at least 110% of the fair market value of
the stock subject to the option on the date of grant, and the term of the option
does not exceed five years from the date of grant. The aggregate fair market
value, determined at the time of grant, of the shares of Common Stock with
respect to which incentive stock options are exercisable for the first time by
an optionee during any calendar year (under all such plans of the Company and
its affiliates) may not exceed $100,000. Upon the expiration of the transition
rule extending the effective date of Code Section 162(m) for newly public
companies, no person shall be eligible to receive options under the Incentive
Plan covering more than 500,000 shares in any calendar year.
 
     Shares subject to stock awards that have expired or otherwise terminated
without having been exercised in full (or vested in the case of restricted stock
awards) shall again become available for the grant of awards under the Incentive
Plan, including shares subject to currently outstanding options and restricted
stock issued under the 1993 Plan and the 1996 Plans.
 
     The Board of Directors has the authority to reprice outstanding options and
to offer optionees the opportunity to replace outstanding options with new
options for the same or a different number of shares.
 
     Restricted stock purchase awards granted under the Incentive Plan may be
accompanied by a
repurchase option in favor of the Company in accordance with a vesting schedule
and at a price determined by the Board of Directors. Restricted stock purchases
must be at a price equal to at least 85% of the stock's fair market value on the
award date, but stock bonuses may be awarded without a purchase payment. Rights
under a stock bonus or restricted stock bonus agreement may not be transferred
other than by will, the laws of descent and distribution or a qualified domestic
relations order while the stock awarded pursuant to such an agreement remains
subject to the agreement.
 
     Upon a change in control of the Company, any options shall remain
outstanding, be assumed by the acquiror or be substituted with similar options.
In the event the acquiror refuses to assume, substitute or continue any options,
then vested options shall be terminated if not exercised prior to the change of
control. For purposes of this Incentive Plan, "change in control" means: any
consolidation or merger of the Company with or into any other entity or person,
or any other corporate reorganization, in which the Company is not the
continuing or surviving entity, or any transaction or series of related
transactions by the Company in which in excess of 50% of the Company's voting
power is transferred, or any sale, lease, license or other disposition of all or
substantially all of the assets of the Company.
 
   
     As of March 31, 1998, 46,395 shares of Common Stock had been issued upon
the exercise of options granted under the 1996 Plans, options to purchase
2,344,103 shares of Common Stock at a weighted average exercise price of $5.48
were outstanding and 1,095,323 shares remained available for future grant under
the 1996 Plans. As of March 31, 1998, 3,235,079 shares (net of repurchases) of
Common Stock had been issued under the 1993 Plan and 59,921 shares remained
available for future grant under the 1993 Plan. The Incentive Plan will
terminate in October 2007 unless sooner terminated by the Board of Directors.
    
 
     Employee Stock Purchase Plan. In October 1997, the Company's Board of
Directors approved the Employee Stock Purchase Plan (the "Purchase Plan")
covering an aggregate of 150,000 shares of Common Stock. The Purchase Plan is
intended to qualify as an employee stock purchase plan within the meaning of
Section 423 of the Code. Under the Purchase Plan, the Board of Directors may
authorize participation by eligible employees, including officers, in periodic
offerings following the adoption of the Purchase Plan. The offering period for
any offering will be no more than 27 months.
 
     Under the Purchase Plan, employees are eligible to participate if they are
employed by the Company or an affiliate of the Company designated by the Board
of Directors and are employed at
                                       47
<PAGE>   49
 
least 20 hours per week and five months per year. Employees who participate in
an offering will have the right to purchase up to the number of shares of Common
Stock purchasable with a percentage designated by the Board of Directors, up to
15%, of an employee's earnings withheld pursuant to the Purchase Plan and
applied, on specified dates determined by the Board of Directors, to the
purchase of shares of Common Stock. The price of Common Stock purchased under
the Purchase Plan will be equal to 85% of the lower of the fair market value of
the Common Stock on the commencement date of each offering period or the
relevant purchase date. Employees may end their participation in the offering at
any time during the offering period, and participation ends automatically on
termination of employment with the Company.
 
     In the event of certain changes of control, the Company and the Board of
Directors has discretion to provide that each right to purchase Common Stock
will be assumed or an equivalent right substituted by the successor corporation,
or the Board may shorten the offering period and provide for all sums collected
by payroll deductions to be applied to purchase stock immediately prior to the
change in control. The Purchase Plan will terminate at the Board's discretion.
 
     1997 Non-Employee Directors' Stock Option Plan. In September 1997, the
Company's Board of Directors adopted the Directors' Plan to provide for the
automatic grant of options to purchase shares of Common Stock to non-employee
directors of the Company. The Directors' Plan is administered by the Board,
unless the Board delegates administration to a Committee comprised of members of
the Board.
 
   
     The Directors' Plan provides for the issuance of up to 250,000 shares of
Common Stock. The Directors' Plan provides that each current non-employee
director will automatically be granted an option to purchase 10,000 shares of
Common Stock upon the Effective Date of the Plan, and each person who is
subsequently elected for the first time to be a non-employee director will
automatically be granted an option to purchase 30,000 shares of Common Stock
upon the date of his or her election to the Company's Board of Directors. In
addition, on each anniversary of each directors' initial grant under the
Directors' Plan, each non-employee director will automatically be granted an
option to purchase an additional 10,000 shares of Common Stock. Options under
the Directors' Plan have a 10-year term and will vest over a period of five
years, with 10% of the shares subject to the option vesting on the date six
months following the grant date and the remaining shares vesting ratably on a
daily basis over the next four and one half years. The exercise price of options
under the Directors' Plan must equal the fair market value of the Common Stock
on the date of grant. Options granted under the Directors' Plan are generally
nontransferable. Unless otherwise terminated by the Board of Directors, the
Directors' Plan will terminate in September 2007.
    
 
   
     As of March 31, 1998, options to purchase 50,000 shares of Common Stock
with a weighted average exercise price of $11.00 per share were outstanding
under the Directors' Plan.
    
 
     1997 Restricted Stock Bonus Plan. In October 1997, the Board of Directors
of the Company adopted a stock bonus plan (the "1997 Restricted Stock Bonus
Plan"). The 1997 Restricted Stock Bonus Plan allows the Company to award Common
Stock to certain employees, directors, and consultants of the Company, in
consideration for services rendered to the Company. The 1997 Restricted Stock
Bonus Plan is administered by the Board, which determines recipients and the
terms of awards to be granted, including the number of shares subject to the
award.
 
     Stock bonuses granted under the 1997 Restricted Stock Bonus Plan are
granted pursuant to a reacquisition option in favor of the Company, in
accordance with a vesting schedule. Rights under a stock bonus agreement may not
be transferred other than by will, the laws of descent and distribution or a
domestic relations order, during such period as the stock awarded pursuant to
such an agreement remains subject to a reacquisition option.
 
     Upon certain changes in control of the Company, all outstanding awards
under the 1997 Restricted Stock Bonus Plan subject to a reacquisition option
shall either be assumed or substituted by the
 
                                       48
<PAGE>   50
 
surviving entity. If the surviving entity determines not to assume or substitute
such awards, then the awards subject to a reacquisition option shall be
terminated prior to such change in control.
 
   
     There are currently an aggregate of 9,750 shares of Common Stock authorized
for issuance under the 1997 Restricted Stock Bonus Plan. Shares of Common Stock
subject to outstanding restricted stock bonus awards that have been reacquired
by the Company again become available for the grant of stock bonuses under the
plan. As of March 31, 1998, an aggregate of 9,000 shares of Common Stock,
subject to a repurchase option in favor of the Company, were outstanding
pursuant to the 1997 Restricted Stock Bonus Plan.
    
 
     The 1997 Restricted Stock Bonus Plan will terminate upon the closing of the
offering.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
   
     The Company's Bylaws provide that the Company will indemnify its directors
and executive officers and may indemnify its other officers, employees and other
agents to the fullest extent permitted by Delaware law. The Company is also
empowered under its Bylaws to enter into indemnification contracts with its
directors and officers and to purchase insurance on behalf of any person it is
required or permitted to indemnify. Pursuant to this provision, the Company will
enter into indemnification agreements with each of its directors and executive
officers.
    
 
     The Company has obtained officer and director liability insurance with
respect to liabilities arising out of certain matters, including matters arising
under the Securities Act. In addition, the Company's Certificate of
Incorporation provides that, to the fullest extent permitted by Delaware law,
the Company's directors will not be liable for monetary damages for breach of
the directors' fiduciary duty of care to the Company and its stockholders. This
provision in the Certificate of Incorporation does not eliminate the duty of
care, and in appropriate circumstances, equitable remedies such as an injunction
or other forms of non-monetary relief would remain available under Delaware law.
Under current Delaware law, a director's liability to the Company or its
stockholders may not be limited with respect to any breach of the director's
duty of loyalty to the Company or its stockholders, for acts or omissions not in
good faith or involving intentional misconduct, for knowing violations of law,
for any transaction from which the director derived an improper personal
benefit, for improper transactions between the director and the Company, and for
improper distributions to stockholders and loans to directors and officers. This
provision also does not affect a director's responsibilities under any other
laws, such as the federal securities laws or state or federal environmental
laws.
 
     There is no pending litigation or proceeding involving a director or
officer of the Company as to which indemnification is being sought, nor is the
Company aware of any pending or threatened litigation that may result in claims
for indemnification by any director or officer.

                          DESCRIPTION OF CAPITAL STOCK
 
     Upon completion of this offering, the authorized capital stock of the
Company will consist of 35,000,000 shares of Common Stock, $.001 par value, and
5,000,000 shares of Preferred Stock, $.001 par value.
 
COMMON STOCK
 
   
     As of March 31, 1998, there were 12,830,627 shares of Common Stock
outstanding held of record by 149 stockholders, after giving effect to the
conversion of all outstanding shares of Preferred Stock into Common Stock upon
the closing of this offering. Based upon the number of shares outstanding as of
that date and giving effect to the issuance of the 2,220,000 shares of Common
Stock offered by the Company hereby, there will be 15,050,627 shares of Common
Stock outstanding on the closing of this offering.
    
 
     The holders of Common Stock are entitled to one vote for each share held of
record on all matters submitted to a vote of the stockholders. The holders of
Common Stock are entitled to receive ratably such dividends as may be declared
by the Board of Directors out of funds legally available therefor. See "Dividend
Policy." In the event of a liquidation, dissolution or winding up of the
Company, holders of the Common Stock are entitled to share ratably in all assets
remaining after payment of liabilities. Holders of Common Stock have no
preemptive rights and no right to convert their Common Stock into any other
securities. There are no redemption or sinking fund provisions applicable to the
Common Stock. All outstanding shares of Common Stock are, and all shares of
Common Stock to be outstanding upon completion of this offering will be, fully
paid and nonassessable.
 
PREFERRED STOCK
 
   
     The Board of Directors has the authority, without further action by the
stockholders, to issue up to 5,000,000 shares of Preferred Stock, $.001 par
value, in one or more series and to fix the rights, preferences, privileges and
restrictions thereof, including dividend rights, conversion rights, voting
rights, terms of redemption, liquidation preferences, sinking fund terms and the
number of shares constituting any series or the designation of such series,
without any further vote or action by stockholders. The issuance of Preferred
Stock could adversely affect the voting power of holders of Common Stock and the
likelihood that such holders will receive dividend payments and payments upon
liquidation and could have the effect of delaying, deferring or preventing a
change in control of the Company. Other than pursuant to the warrants described
in Note 7 of Notes to Consolidated Financial Statements, the Company has no
present plan to issue any shares of Preferred Stock.
    
 
   
WARRANTS
    
   
    
 
   
     As of March 31, 1998, in connection with a capital equipment lease and loan
and security agreements, the Company had outstanding warrants to purchase 60,936
shares of Series D Preferred Stock, and an outstanding warrant to purchase
125,000 shares of Common Stock in connection with a loan financing, at exercise
prices of $8.00 per share. The warrants expire at various times from 3.0 to 5.0
years following the closing of this offering. Each warrant contains provisions
for the adjustment of the exercise price and the aggregate number of shares
issuable upon the exercise of the warrant under certain circumstances, including
stock dividends, stock splits, reorganizations, reclassifications,
consolidations and certain dilutive sales of the securities for which the
warrant is exercisable at prices below the then existing exercise price. Each
warrant may be exercised, without the payment of cash, for the number of shares
of Preferred Stock or Common Stock, as applicable, purchasable, at the current
market value of the Preferred Stock or Common Stock, as applicable, by the
difference between the aggregate exercise price of the warrant and the value, at
the current market price per share of Preferred Stock or Common Stock, as
applicable, of the aggregate number of shares purchasable under the warrant.
Upon the closing of the offering, the warrants to purchase Series D Preferred
Stock will
    
 
                                       53
<PAGE>   55
 
become warrants exercisable to purchase the same number of shares of Common
Stock at an exercise price of $8.00 per share.
 
   
REGISTRATION RIGHTS
    
 
   
     Following this offering, holders (or their permitted transferees)
("Holders") of approximately 10,749,153 shares of Common Stock and warrants to
purchase 185,936 shares of Common Stock (assuming the conversion of all
outstanding Preferred Stock upon the closing of this offering) will be entitled
to certain rights with respect to the registration of their shares under the
Securities Act. Under the terms of that certain Amended and Restated Investor
Rights Agreement dated April 1, 1998 (the "Investor Rights Agreement"), if the
Company proposes to register any of its securities under the Securities Act,
either for its own account or the account of others, subject to certain
restrictions, the Holders are entitled to notice of such registration and are
entitled to include all or part of their shares of Common Stock; provided, among
other conditions, that the underwriters of any offering have the right to limit
the number of such shares included in such registration or exclude such shares
entirely. The Holders may also require the Company, beginning one year after the
date of this Prospectus, on not more than two occasions, to file a registration
statement under the Securities Act at the Company's expense with respect to
their shares of Common Stock, and the Company is required to use its best
efforts to effect such registration, subject to certain conditions and
limitations. Further, the Holders may also require the Company, at the Company's
expense, to register all or a portion of their shares of Common Stock on Form
S-3 when such form becomes available to the Company, subject to certain
conditions and limitations.
    
 
DELAWARE LAW AND CERTAIN CHARTER PROVISIONS
 
     The Company is subject to the provisions of Section 203 of the Delaware
General Corporation Law, an anti-takeover law. In general, the statute prohibits
a publicly-held Delaware corporation from engaging in a "business combination"
with an "interested stockholder" for a period of three years after the date of
the transaction in which the person became an interested stockholder, unless the
business combination is approved in a prescribed manner. For purposes of Section
203, a "business combination" includes a merger, asset sale or other transaction
resulting in a financial benefit to the interested stockholder, and an
"interested stockholder" is a person who, together with affiliates and
associates, owns (or within three years prior, did own) 15% or more of the
corporation's voting stock.
 
     The Company's Certificate of Incorporation and Bylaws also require that,
effective upon the closing of this offering, any action required or permitted to
be taken by stockholders of the Company must be effected at a duly called annual
or special meeting of the stockholders and may not be effected by a consent in
writing. In addition, special meetings of the stockholders of the Company may be
called only by the Board of Directors, the Chairman of the Board, the Chief
Executive Officer of the Company or by any person or persons holding shares
representing at least 50% of the outstanding capital stock. The Company's
Certificate of Incorporation also provides for the classification of the Board
of Directors into three classes, only one of which will be elected at each
annual meeting, and specifies that the authorized number of directors may be
changed only by resolution of the Board of Directors. These provisions, which
require the vote of stockholders holding at least two-thirds of the outstanding
shares to amend, may have the effect of deterring hostile takeovers or delaying
changes in control or management of the Company. See "Management -- Board
Composition."
 
TRANSFER AGENT AND REGISTRAR
 
     American Securities Transfer & Trust, Inc. has been appointed as the
transfer agent and registrar for the Company's Common Stock.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Prior to this offering, there has not been any public market for the Common
Stock of the Company. Further sales of substantial amounts of Common Stock in
the open market may adversely affect the market price of the Common Stock
offered hereby. Furthermore, since only a limited number of shares will be
available for sale shortly after this offering because of certain contractual
and legal restrictions on resale described below, sales of Common Stock in the
market after the restrictions lapse could adversely affect the prevailing market
price and the ability of the Company to raise equity capital in the future.
 
   
     Upon completion of this offering, based on the number of shares outstanding
as of March 31, 1998, the Company will have outstanding an aggregate of
15,050,627 shares of Common Stock assuming (i) the issuance by the Company of
shares of Common Stock offered hereby, (ii) no issuance of 185,936 shares of
Common Stock relating to outstanding warrants, (iii) no exercise of exercisable
vested options (as of March 31, 1998) to purchase 461,570 shares of Common
Stock, and (iv) no exercise of the Underwriters' over-allotment option to
purchase 360,000 shares of Common Stock. Of these shares, 2,400,000 shares sold
in this offering will be freely tradable without restriction or further
registration under the Securities Act, except for shares held by "affiliates" of
the Company as that term is defined in Rule 144 under the Securities Act (whose
sales would be subject to certain limitations and restrictions described below)
and the regulations promulgated thereunder.
    
 
   
     The remaining 12,650,627 outstanding shares of the Company's Common Stock
were sold by the Company to officers, directors, employees, consultants and
other stockholders of the Company in reliance on exemptions from the
registration requirements of the Securities Act and are "restricted" securities
within the meaning of Rule 144 and Rule 701 under the Securities Act. 12,505,006
of these shares and an additional 691,504 shares issuable upon exercise of
outstanding vested options will be eligible for sale 180 days after the date of
this Prospectus upon expiration of the lock-up agreements described below and in
compliance with certain limitations set forth in the Securities Act. An
additional 145,621 of the outstanding shares will become eligible for sale at
various times after 180 days after the date of this Prospectus. Additionally,
854,158 of the outstanding shares, that would otherwise be eligible for sale as
set forth above, are contractually restricted shares subject to rights of
repurchase in favor of the Company that expire at various dates through July 25,
2001 pursuant to monthly vesting.
    
 
   
     Each officer, director and other stockholders of the Company, who together
hold an aggregate of 12,650,627 shares of Common Stock and exercisable vested
options to purchase 461,570 shares of Common Stock not being sold in the
offering, have agreed with the representatives of the Underwriters or the
Company for a period of 180 days after the date of this Prospectus, they will
not, directly or indirectly, offer, sell, contract to sell, grant any option to
sell or otherwise dispose of, directly or indirectly, any shares of Common Stock
or securities convertible into or exchangeable for, or any rights to purchase or
acquire, Common Stock, without the prior written consent of BancAmerica
Robertson Stephens or, in certain instances, the Company. The Company has agreed
with BancAmerica Robertson Stephens not to release any stockholder from any
lock-up agreement between the stockholder and the Company without the consent of
BancAmerica Robertson Stephens.
    
 
     In general, under Rule 144 as currently in effect, beginning 180 days after
the date of this Prospectus, an affiliate of the Company, or person (or persons
whose shares are aggregated) who has beneficially owned restricted securities
that were not acquired from the Company or an affiliate of the Company within
the previous one year, will be entitled to sell in any three-month period a
number of shares that does not exceed the greater of (i) 1% of the then
outstanding shares of the Company's Common Stock or (ii) the average weekly
trading volume of the Company's Common Stock in the Nasdaq National Market
during the four calendar weeks immediately preceding the date on which notice of
the sale is filed with the Securities and Exchange Commission. Sales pursuant to
Rule 144 are subject to certain requirements relating to manner of sale, notice
and availability of current public information about the Company. A person (or
person whose shares are aggregated) who is not deemed
 
                                       55
<PAGE>   57
 
to have been an affiliate of the Company at any time during the 180 days
immediately preceding the sale and who beneficially owns restricted securities
is entitled to sell such shares pursuant to Rule 144(k) without regard to the
limitations described above; provided that at least two years have elapsed since
the later of the date the shares were acquired from the Company or from an
affiliate of the Company.
 
     An employee, officer or director of or consultant to the Company who
purchased or was awarded shares or options to purchase shares pursuant to a
written compensatory plan or contract is entitled to rely on the resale
provisions of Rule 701 under the Securities Act, which permits affiliates and
non-affiliates to sell their Rule 701 shares without having to comply with Rule
144's holding period restrictions, in each case commencing 180 days after the
date of this Prospectus. In addition, non-affiliates may sell Rule 701 shares
without complying with public information, volume and notice provisions of Rule
144.
 
     The Company intends to file a registration statement under the Securities
Act to register 4,625,000, 250,000 and 150,000 shares of Common Stock reserved
for issuance under the Incentive Plan, Directors' Plan and the Purchase Plan,
respectively, thus permitting the resale of such shares by nonaffiliates in the
public market without restriction under the Securities Act. Such registration
statement will become effective immediately upon filing.
 
   
     As of the date of this Prospectus, warrants to purchase an aggregate of
185,936 shares of Common Stock were outstanding, all of which are subject to the
180-day lock-up.
    
 
   
     In addition, after this offering, the holders of approximately 10,749,153
shares of Common Stock and warrants to purchase 185,936 shares of Common Stock
(assuming the conversion of all outstanding Preferred Stock upon the closing of
this offering) will be entitled to certain rights with respect to registration
of such shares under the Securities Act. Registration of such shares under the
Securities Act would result in such shares becoming freely tradable without
restriction under the Securities Act (except for shares purchased by affiliates
of the Company, which will be subject to certain restrictions) immediately upon
the effectiveness of such registration. See "Description of Capital Stock --
Registration Rights."

     The Representatives have advised the Company and the Selling Stockholders
that the Underwriters propose to offer the shares of Common Stock to the public
at the initial public offering price set forth on the cover page of this
Prospectus and to certain dealers at such price less a concession of not more
than $          per share, of which $          may be reallowed to other
dealers. After the public offering, the initial public offering price,
concession and reallowance to dealers may be reduced by the Representatives. No
such reduction shall change the amount of proceeds to be received by the Company
as set forth on the cover page of this Prospectus.
    
 
   
     The Company has granted to the Underwriters an option, solely to cover
over-allotments, exercisable during the 30-day period after the date of this
Prospectus, to purchase up to 360,000 additional shares of Common Stock at the
same price per share as will be paid for the 2,400,000 shares that the
Underwriters have agreed to purchase. To the extent that the Underwriters
exercise such option, each of the Underwriters will have a firm commitment to
purchase approximately the same percentage of such additional shares that the
number of shares of Common Stock to be purchased by it shown in the above table
represents as a percentage of the 2,400,000 shares offered hereby. If purchased,
such additional shares will be sold by the Underwriters on the same terms as
those on which the 2,400,000 shares are being sold.
    
 
     The Underwriting Agreement contains covenants of indemnity among the
Underwriters, the Company and the Selling Stockholders against certain civil
liabilities, including liabilities under the Securities Act and liabilities
arising from breaches of representations and warranties contained in the
Underwriting Agreement.
 
     Each officer and director and certain holders of shares of the Company's
Common Stock have agreed with the Representatives, for a period of 180 days
after the date of this Prospectus (the "Lock-Up Period"), subject to certain
exceptions, not to offer to sell, contract to sell, or otherwise sell, dispose
of, loan, pledge or grant any rights with respect to any shares of Common Stock,
any options or warrants to purchase any shares of Common Stock, or any
securities convertible into or exchangeable for shares of Common Stock owned as
of the date of this Prospectus or thereafter acquired directly by such holders
or with respect to which they have or hereafter acquire the power of
disposition, without the prior written consent of BancAmerica Robertson
Stephens. However, BancAmerica Robertson Stephens may, in its sole discretion
and at any time without notice, release all or any portion of the securities
subject to lock-up agreements. There are no agreements between the
Representatives and any of the Company's stockholders providing consent by the
Representatives to the sale of shares prior
 
                                       57
<PAGE>   59
 
to the expiration of the Lock-Up Period. The Company has agreed that during the
Lock-Up Period, the Company will not, subject to certain exceptions, without the
prior written consent of BancAmerica Robertson Stephens, (i) consent to the
disposition of any shares held by stockholders prior to the expiration of the
Lock-Up Period or (ii) issue, sell, contract to sell or otherwise dispose of,
any shares of Common Stock, any options or warrants to purchase any shares of
Common Stock or any securities convertible into, exercisable for or exchangeable
for shares of Common Stock, other than the Company's sale of shares in this
offering, the issuance of Common Stock upon the exercise of outstanding options
and warrants and the Company's issuance of options and stock under existing
stock option and stock purchase plans. See "Shares Eligible for Future Sale."
 
     The Representatives have advised the Company that they do not intend to
confirm sales to any accounts over which they exercise discretionary authority.
 
   
     In February 1998, the Company agreed in principle to enter into a
transaction with Hambrecht & Quist Guaranty Finance, LLC ("Guaranty Finance"),
whereby Guaranty Finance would loan the Company up to $5 million. Under the
related agreements which were executed on March 12, 1998, (i) Guaranty Finance
agreed to lend the Company up to $5 million at an interest rate of 12% per
annum, $1.1 million of which was loaned to the Company on March 13, 1998 (the
"Loan") and (ii) Guaranty Finance purchased from the Company for $1,250 a
warrant to purchase 125,000 shares of the Company's Common Stock at a purchase
price of $8.00 per share. The Company has an option to repurchase up to 62,500
shares dependent on the level of borrowings over the term of the financing
arrangement. The warrant is exercisable through March 1, 2003. The Company paid
a $100,000 fee to Guaranty Finance in consideration for entering into the
aforementioned loan transaction. The Company anticipates that $1.1 million of
the net proceeds of this offering will be used to pay the outstanding balance of
the Loan. The majority equity holder of each of Guaranty Finance and Hambrecht &
Quist LLC is Hambrecht & Quist Group.
    
 
     Prior to this offering, there has been no public market for the Common
Stock of the Company. Consequently, the initial public offering price for the
Common Stock offered hereby will be determined through negotiations between the
Company and the Representatives. Among the factors to be considered in such
negotiations are prevailing market conditions, certain financial information of
the Company, market valuations of other companies that the Company and the
Representatives believe to be comparable to the Company, estimates of the
business potential of the Company, the present state of the Company's
development and other factors deemed relevant.
 
     The Representatives have advised the Company that, pursuant to Regulation M
under the Securities Act, certain persons participating in the offering may
engage in transactions, including stabilizing bids, syndicate covering
transactions or the imposition of penalty bids, which may have the effect of
stabilizing or maintaining the market price of the Common Stock at a level above
that which might otherwise prevail in the open market. A "stabilizing bid" is a
bid for or the purchase of the Common Stock on behalf of the Underwriters for
the purpose of fixing or maintaining the price of the Common Stock. A "syndicate
covering transaction" is the bid for or the purchase of the Common Stock on
behalf of the Underwriters to reduce a short position incurred by the
Underwriters in connection with the offering. A "penalty bid" is an arrangement
permitting the Representatives to reclaim the selling concession otherwise
accruing to an Underwriter or syndicate member in connection with the offering
if the Common Stock originally sold by such Underwriter or syndicate member is
purchased by the Representatives in a syndicate covering transaction and has
therefore not been effectively placed by such Underwriter or syndicate member.
The Representatives have advised the Company that such transactions may be
effected on the Nasdaq National Market or otherwise and, if commenced, may be
discontinued at any time.
 
   
     Of the 2,220,000 shares to be sold by the Company, a portion may be offered
directly to corporate partners of the Company (the "Direct Purchasers") at the
price to the public indicated on the cover page of this Prospectus (the "Direct
Placement"). This purchase would be pursuant to an agreement between the Company
and the Direct Purchasers and not pursuant to the Underwriting Agreement.

The Underwriters would not receive any fees or commissions in connection with
the Direct Placement.
    
 
                                 LEGAL MATTERS
 
   
     The validity of the Common Stock offered hereby will be passed upon for the
Company by Cooley Godward LLP ("Cooley Godward"), Palo Alto, California. Certain
legal matters in connection with this offering will be passed upon for the
Underwriters by Wilson Sonsini Goodrich & Rosati, Professional Corporation, Palo
Alto, California. As of the date of this Prospectus, certain members and
associates of Cooley Godward own through an investment partnership an aggregate
of 98,958 shares of Common Stock of the Company.
    
 
                                    EXPERTS
 
   
     The consolidated financial statements of the Company as of December 31,
1996 and 1997 and for each of the three years in the period ended December 31,
1997 included in this Prospectus have been so included in reliance on the report
of Price Waterhouse LLP, independent accountants, given on the authority of said
firm as experts in auditing and accounting.
    
 
                             CHANGE OF ACCOUNTANTS
 
     On July 19, 1996, as a result of a decision by the Company to outsource to
KPMG its accounting and data processing functions, KPMG resigned as the
Company's independent accountants. On November 1, 1996, Price Waterhouse LLP was
engaged as the Company's independent accountants. The resignation of KPMG and
appointment of Price Waterhouse LLP was approved by the Company's Board of
Directors. Prior to November 1, 1996, the Company had not consulted with Price
Waterhouse LLP on items which included the Company's accounting principles or
the form of audit report to be issued on the Company's financial statements.
 
     The reports of KPMG on the financial statements of the Company for the two
years ended December 31, 1994 and 1995, did not contain an adverse opinion or a
disclaimer of opinion and were not qualified or modified as to uncertainty,
audit scope, or accounting principles.
 
     In connection with the audits by KPMG of the two years of the Company ended
December 31, 1995, and during the subsequent interim period through July 19,
1996, there were no disagreements between the Company and KPMG on any matter of
accounting principles or practice, financial statement disclosure or auditing
scope or procedures, which if not solved to the satisfaction of KPMG, would have
caused them to make reference to the matter in their report. KPMG has not
audited or reported on any financial statements of the Company subsequent to
December 31, 1995.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders of
First Virtual Corporation
 
   
     In our opinion, the accompanying consolidated balance sheets and the
related consolidated statements of operations, of stockholders' equity and of
cash flows present fairly, in all material respects, the financial position of
First Virtual Corporation and its subsidiary at December 31, 1996 and 1997 and
the results of their operations and their cash flows for each of the three years
in the period ended December 31, 1997, in conformity with generally accepted
accounting principles. 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 of these
statements in accordance with generally accepted auditing standards which
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, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.

                           FIRST VIRTUAL CORPORATION
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1 -- THE COMPANY AND A SUMMARY OF ITS SIGNIFICANT ACCOUNTING POLICIES:
 
  The Company
 
   
     First Virtual Corporation (the "Company") was incorporated in California in
October 1993 and reincorporated in Delaware in December 1997. The Company
develops, manufactures and markets video networking systems for use in business,
government and educational environments.
    
 
   
     In October 1997, the Company's Board of Directors authorized, and the
stockholders subsequently approved, the reincorporation of the Company in
Delaware, which was effected on December 2, 1997. All per share amounts have
been adjusted in the accompanying consolidated financial statements to reflect
the reincorporation in Delaware. The Board also authorized and the stockholders
subsequently approved, an increase in the authorized shares of Common Stock to
35,000,000 and a decrease in the authorized shares of Preferred Stock to
5,000,000 to be effective upon the closing of the offering contemplated by this
prospectus (the "Offering").
    
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements, and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
   
  Principles of Consolidation
    
 
     The consolidated financial statements include the accounts of the Company
and its wholly owned subsidiary. All significant intercompany accounts and
transactions have been eliminated.
 
  Cash Equivalents
 
     The Company considers all highly liquid investments with a maturity of
three months or less when purchased to be cash equivalents.
 
  Inventory
 
     Inventory is stated at the lower of cost or market, cost being determined
using the first-in, first-out method.
 
  Restricted Cash
 
   
     As of December 31, 1996 and 1997, the Company's other assets included
restricted cash of $135,000, representing collateral for an outstanding letter
of credit, which expires April 28, 1998.
    
 
  Property and Equipment
 
     Property and equipment are stated at cost. Depreciation is computed using
the straight-line method over the estimated useful lives of the assets,
generally three years. Leasehold improvements are amortized using the
straight-line method over the shorter of the estimated useful lives of the
assets or the remaining lease term.

                           FIRST VIRTUAL CORPORATION
 
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
  Long-Term Assets
 
     The Company periodically reviews the recoverability of long-term assets
whenever events or changes in circumstances indicate that the carrying amount of
an asset might not be recoverable.
 
  Revenue Recognition
 
     Revenues are recognized upon shipment of product to customers, provided no
significant obligations remain and collectibility is probable. Revenues from
sales to certain of the Company's distributors are subject to agreements
allowing rights of return and price protection. Accordingly, the Company
provides for estimated future returns and credits for price protection upon
revenue recognition. Such reserves are estimated based upon historical rates of
returns and allowances, distributor inventory levels, the Company's estimates of
expected sell-through by distributors and other related factors. Actual results
could differ from these estimates.
 
     Advance payments received from customers are recorded as deferred revenue
and are recognized as revenue upon shipment of product.
 
     The Company on occasion receives nonrecurring engineering funding for
development projects. Revenues from such funding are recognized over the term of
the respective contract using the percentage of completion method. Amounts
received under such projects have not been material to date.
 
     A provision is made upon revenue recognition for the estimated cost to
repair or replace products under warranty arrangements. The Company provides a
limited amount of telephone technical support to customers. These activities are
generally considered insignificant customer support obligations and related
costs are accrued upon revenue recognition.
 
  Software Development Costs
 
     Software development costs incurred prior to the establishment of
technological feasibility are included in research and development and are
expensed as incurred. Software development costs incurred subsequent to the
establishment of technological feasibility through the period of general market
availability of the product are capitalized, if material. To date, all software
development costs have been expensed as incurred.
 
  Stock-Based Compensation
 
   
     The Company accounts for employee stock-based compensation using the
intrinsic value method prescribed in Accounting Principles Board Opinion (APB)
No. 25, "Accounting for Stock Issued to Employees," and related Interpretations.
Options and warrants granted to non-employees are accounted for using the fair
value method prescribed by Statement of Financial Accounting Standards No. 123
(FAS 123), "Accounting for Stock-Based Compensation." The Company also provides
additional pro forma disclosures as required under FAS 123. (See Note 8)
    
 
  Income Taxes
 
     Income taxes are accounted for using an asset and liability approach. The
asset and liability approach requires the recognition of taxes payable or
refundable for the current year and deferred tax liabilities and assets for the
future tax consequences of events that have been recognized in the Company's
financial statements or tax returns. The measurement of current and deferred tax
liabilities and assets are based on provisions of currently enacted tax law; the
effects of future changes in tax laws

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
or rates are not anticipated. The measurement of deferred tax assets is reduced,
if necessary, by the amount of any tax benefits that, based on available
evidence, are not expected to be realized.
 
   
  Net Loss Per Share
    
 
   
     The Company has adopted the provisions of Statement of Financial Accounting
Standards No. 128, "Earnings Per Share" (FAS 128). FAS 128 requires the Company
to report both basic earnings (loss) per share, which is based on the
weighted-average number of common shares outstanding excluding contingently
issuable or returnable shares such as shares of unvested restricted Common
Stock, and diluted earnings (loss) per share, which is based on the
weighted-average number of common shares outstanding and dilutive potential
common shares outstanding. As a result of the losses incurred by the Company
during 1995, 1996 and 1997, all potential common shares were anti-dilutive and
excluded from the diluted net loss per share calculations.
    
 
   
     The following table summarizes securities outstanding as of each period end
which were not included in the calculation of diluted net loss per share since
their inclusion would be anti-dilutive:

     Unvested restricted Common Stock represents stock that has been issued but
which is subject to repurchase to the extent the holder does not remain
associated with the Company until such shares are vested. Each share of
Preferred Stock is convertible into one share of Common Stock. The Preferred
Stock warrants are exercisable at $8.00 per share and expire at various times
from 3 to 4.3 years following the closing of an initial public offering. The
stock options outstanding at December 31, 1996 and 1997 had a weighted average
exercise price of $2.60 and $5.71, respectively, and expire beginning in July
2001 through December 2007.
    
 
   
  Pro Forma Stockholders' Equity (unaudited)
    
 
   
     If the Offering contemplated by this prospectus is consummated, all shares
of Preferred Stock outstanding at the closing date will automatically convert
into an aggregate of 8,040,153 shares of Common Stock. The pro forma effect of
such conversion has been reflected in the accompanying unaudited pro forma
stockholders' equity as of December 31, 1997.
    
 
   
  Pro Forma Net Loss Per Share (unaudited)
    
 
   
     Pro forma net loss per share for 1997 has been computed assuming the
conversion of 8,040,153 shares of Preferred Stock outstanding as of December 31,
1997 into shares of Common Stock which will occur upon completion of the

     Financial instruments that potentially subject the Company to significant
concentrations of credit risk consist principally of cash, cash equivalents and
trade accounts receivable. The Company places its cash and cash equivalents
primarily in market rate accounts with high quality financial institutions. The
Company sells its products to original equipment manufacturers, distributors,
value added resellers and end-user customers throughout the world. The Company

its customers' financial condition and generally requires no collateral from its
customers. The Company provides an allowance for uncollectible accounts
receivable based upon the expected collectibility of such receivables. To date,
the Company has not experienced any significant bad debts.
 
   
     In 1995, revenues from two customers represented 24% and 17% of total
revenues. In 1996 and 1997, revenues from one customer represented 29% and 64%
of total revenues, respectively.
    
 
     The following table summarizes the percentage of total revenues accounted
for by shipments to customers outside North America:

     At December 31, 1996, outstanding receivables from two customers
represented 27% and 10% of accounts receivable. At December 31, 1997,
outstanding receivables from three customers represented 39%, 18% and 15% of
accounts receivable.
    
 
  Fair Value of Financial Instruments
 
     The carrying amount of cash and cash equivalents and other current assets
and liabilities such as accounts receivable, accounts payable and accrued
liabilities, as presented in the financial statements, approximates fair value
based on the short-term nature of these instruments. The recorded amount of
long-term debt approximates fair value as the actual interest rates approximate
current competitive rates.
 
  New Accounting Pronouncements
 
   
     In June 1997, the Financial Accounting Standards Board issued Statements of
Financial Accounting Standards No. 130 "Reporting Comprehensive Income" (FAS
130) and No. 131 "Disclosures about Segments of an Enterprise and Related
Information" (FAS 131). The Company currently believes that FAS 130 and 131 will
not have any material impact on its financial statement reporting requirements.
    
 
  Dependence on Suppliers
 
     The Company's ability to timely deliver its products is dependent upon the
availability of quality components and subsystems used in these products. The
Company depends in part upon subcontractors to manufacture, assemble and deliver
certain items in a timely and satisfactory manner. The Company obtains certain
components and subsystems from single or a limited number of sources. A
significant interruption in the delivery of such items could have a material
adverse effect on the Company's financial condition and results of operations.

Interest on borrowings is set at the bank's prime rate (8.5% at December 31,
1997) plus 0.75%. Among other provisions, the Company is required to maintain
certain financial covenants and is prohibited from paying dividends. The line of

approximately $500,000 was available to the Company. At December 31, 1997, the
Company was not in compliance with certain covenants, for which the bank issued
a waiver.

     Based on a number of factors, including the lack of a history of profits
and the fact that the Company competes in a developing market that is
characterized by rapidly changing technology, management believes that the
weight of available evidence indicates that it is more likely than not that the
Company will not be able to realize its deferred tax assets and thus a full
valuation allowance has been provided at December 31, 1996 and 1997.
    
 
   
     At December 31, 1997, the Company had federal net operating loss

Common Stock and Preferred Stock based upon the number of shares of Common Stock
held by each, assuming conversion of all Preferred Stock, until the holders of
Preferred Stock receive two times their original per share preference.
Thereafter, the remaining assets will be distributed to the holders of Common
Stock.
 
  Voting Rights
 
     The holders of Preferred Stock have one vote for each share of Common Stock
into which such Preferred Stock may be converted.
 
  Conversion
 
   
     Each share of Preferred Stock is convertible at any time into one share of
Common Stock at the option of the holder, subject to adjustment for dilution.
Such conversion is automatic upon the earlier of the date specified by vote,
written consent or agreement of holders of at least two-thirds of such series
then outstanding or immediately upon the closing date of a public offering of
the Company's Common Stock for which the aggregate net proceeds exceed
$10,000,000 and the per share offering price equals or exceeds $8.00, subject to
adjustment for dilution. At December 31, 1997, a total of 8,040,153 shares of
Common Stock have been reserved for issuance upon conversion of the Preferred
Stock.
    
 
  Series D Preferred Stock Warrants
 
   
     During 1997, the Company issued warrants to purchase 60,936 shares of its
Series D Preferred Stock at $8.00 per share in conjunction with certain
financing arrangements. The warrants are exercisable immediately and expire at
various times from 3 to 4.3 years following the closing of an initial public
offering. Upon closing of the Offering these warrants will become warrants to
purchase the same number of shares of Common Stock at an exercise price of $8.00
per share. As of December 31, 1997, no warrants had been exercised. The
aggregate value of these warrants was estimated by the Company, using the
Black-Scholes model, at approximately $233,000 and is being expensed as
additional cost of financing over the term of the related borrowings.
    
 
NOTE 8 -- STOCK PLANS:
 
  1993 Employee, Consultant and Director Stock Purchase Plan
 
   
     In December 1993, the Company adopted a stock purchase plan (the "1993
Plan"). As of December 31, 1997, a total of 3,295,000 shares of Common Stock had
been authorized for issuance of stock purchase rights awarded under the 1993
Plan. The 1993 Plan, which expires in 2003 unless terminated earlier, is
administered by the Board of Directors and provides for the granting of rights
to purchase the Company's Common Stock. All awards have been made at a purchase
price equal to at least 100% of the fair value of the stock as determined by the
Board of Directors on the date of grant. Stock purchase rights granted under the
1993 Plan must be exercised at the time of grant. Common Stock issued under the
1993 Plan generally vests 10% after six months and ratably each month over the
remaining fifty-four month period, provided that the grantee remains associated
with the Company. In the event that the grantee's continuous status as an
employee, director or consultant terminates, the Company has the right to
repurchase all unvested shares of Common Stock issued upon exercise of an award
at a repurchase price equal to the original issuance price of such shares. As of
December 31, 1997, a total of 3,787,068 shares of the Company's Common Stock had
been issued under the 1993 Plan, 504,084 shares had been repurchased or
cancelled pursuant to the Company's repurchase rights, and approximately
1,198,127 shares were subject to the Company's right of repurchase.

  1996 Stock Purchase Bonus Plan
 
   
     In February 1996, the Company adopted an employee stock purchase bonus plan
(the "1996 Plan") and reserved 125,000 shares of Series C Preferred Stock
("Series C") for issuance to eligible employees upon the exercise of stock
purchase rights awarded under the 1996 Plan. The 1996 Plan, which expires in
2006 unless terminated earlier, is administered by the Board of Directors and
provides for the grant of rights to purchase shares of Series C at a purchase
price equal to 100% of the fair value of the stock as determined by the Board of
Directors on each offering date. Offering periods begin on the first day of the
second month following the end of each calendar quarter (the "Offering Date")
and end ten business days later. On each Offering Date, eligible employees are
granted the right to purchase the number of shares of Series C purchasable with
up to 100% of such employee's bonus amount attributable to the calendar quarter
ended immediately prior to the Offering Date. Each offering contains a single
purchase date occurring ten business days following the Offering Date of such
offering. During 1996 and 1997, the Company issued 81,260 shares and 20,518
shares, respectively, of Series C at prices ranging from $4.00 to $11.00 per
share under the 1996 Plan.
    
 
  1996 Stock Option Plans
 
   
     The Company has two stock option plans which were adopted in 1996 (the
"Stock Option Plans"). The Stock Option Plans, which expire in 2006, provide for
the grant of incentive stock options and nonstatutory stock options to
employees, directors and consultants. The Board of Directors may, at its
discretion, terminate the Stock Option Plans at any time. As of December 31,
1997, 3,485,821 shares of Common Stock had been authorized under the Stock
Option Plans. Options granted under the Stock Option Plans are for periods not
to exceed ten years, and must be issued at prices not less than 100% and 85% for
incentive and nonstatutory stock options, respectively, of the fair value of the
stock, as determined by the Board of Directors on the date of grant. Options
granted to stockholders who own greater than 10% of the outstanding stock are
for periods not to exceed five years and must be issued at prices not less than
110% of the fair value of the stock, as determined by the Board of Directors on
the date of grant. Options granted under the Stock Option Plans are exercisable
immediately and generally vest 10% after six months and ratably each month over
the remaining fifty-four month period, provided that the optionee remains
associated with the Company. In the event that the optionee's continuous status
as an employee, director or consultant terminates, the Company has the right to
repurchase all unvested shares of Common Stock issued upon exercise of an option
at a repurchase price equal to the exercise price of such shares. Additionally,
all unvested options terminate and any vested options must be exercised within
30 days.
    
 
   
     In October 1997, the Board of Directors and stockholders approved the
consolidation and restatement of the Company's 1993 Plan and Stock Option Plans
into the 1997 Equity Incentive Plan to be effective upon the closing of the
Offering. Under the restated plan, 4,625,000 shares of Common Stock may be
issued pursuant to stock awards.
    
 
  1997 Non-Employee Directors' Stock Option Plan
 
   
     In September 1997, the Company's Board of Directors approved the 1997
Non-Employee Director's Stock Option Plan (the "Directors' Plan") and reserved
250,000 shares of the Company's Common Stock for issuance thereunder.
    
 
   
     The Directors' Plan provides for the grant of options to purchase 30,000
shares of Common Stock to each director upon initial election to the Board of
Directors and subsequent automatic grants of options to purchase 10,000 shares
of Common Stock on each anniversary of a previous grant. An initial grant of
10,000 shares was made to each of the five non-employee directors of the Company
in September 1997 upon inception of the Directors' Plan, at a price of $11.00
per share.

  1997 Restricted Stock Bonus Plan
    
 
   
     In October 1997, the Company's Board of Directors adopted a stock bonus
plan (the "1997 Restricted Stock Bonus Plan"). The 1997 Restricted Stock Bonus
Plan provides for the award of Common Stock to certain employees, directors and
consultants in consideration for services rendered to the Company. The 1997
Restricted Stock Bonus Plan is administered by the Board, which determines
recipients and the terms of awards to be granted, including the number of shares
subject to the award. Stock bonuses granted under the 1997 Restricted Stock
Bonus Plan are granted pursuant to a reacquisition option in favor of the
Company, in accordance with a vesting schedule.
    
 
   
     An aggregate of 9,750 shares of Common Stock were authorized for issuance
under the 1997 Restricted Stock Bonus Plan. Shares of Common Stock subject to
outstanding restricted stock bonus awards that are reacquired by the Company
again become available for the grant of stock bonuses under the plan. As of
December 31, 1997, an aggregate of 9,000 shares of Common Stock were outstanding
pursuant to the 1997 Restricted Stock Bonus Plan, subject to a reacquisition
option in favor of the Company. The 1997 Restricted Stock Bonus Plan will
terminate upon the closing of an initial public offering of the Company's Common
Stock.
    
 
   
     Option activity under the Stock Option Plans and the Directors' Plan is
summarized as follows:

granted under the Company's various stock option plans during 1996 and 1997 was
$0.64 and $1.56, respectively. The minimum value of each option was estimated on
the date of grant with the following assumptions for grants during 1996 and
1997: annual dividend yield of 0.0% for both periods; risk-free annual interest
rates of 5.97% to 6.64% and 5.84% to 6.61%, respectively; and an expected option
term of five years for both periods.
    
 
   
  1997 Employee Stock Purchase Plan
    
 
   
     The Company's 1997 Stock Purchase Plan (the "Purchase Plan") was approved
by the Board of Directors and stockholders in October 1997 and will become
effective upon the closing of the Offering. Under the Purchase Plan a total of
150,000 shares of Common Stock have been reserved for issuance to participating
employees who meet eligibility requirements.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
     The Purchase Plan permits eligible employees to purchase Common Stock
through payroll deductions, which may not exceed 15% of an employee's base
compensation, including commissions, bonuses and overtime, at a price equal to
85% of the fair market value of the Common Stock at the beginning of each
offering period or the end of the purchase period, whichever is lower.
 
NOTE 9 -- NOTES RECEIVABLE FROM STOCKHOLDERS:
 
   
     During the period from January 1994 through October 1996, the Company made
full recourse loans to certain executives and employees pursuant to the
Company's 1993 Plan. The loans bear interest at rates ranging from 4.92% to
7.96% per annum and interest on the notes accrues monthly. The loans are due on
the earlier of various dates during 1998 through 2001 or termination of
employment.
    
 
   
NOTE 10 -- SUBSEQUENT EVENTS
    
 
   
     In early February 1998, after considering various factors including the
input provided by the Company's investment bankers, the Board of Directors of
the Company approved a plan under which 499,500 options previously granted at
prices of $10.20 and $11.00 to employees (excluding officers) were exchanged for
options at $8.50 per share, which the Board concluded was the fair value of the
Company's Common Stock at that time.
    
 
   
     In February 1998, the Company agreed in principle to enter into a
transaction with Hambrecht & Quist Guaranty Finance, LLC ("Guaranty Finance")
whereby Guaranty Finance would loan the Company up to $5 million. Under the
related agreements which were executed on March 12, 1998, (i) Guaranty Finance
agreed to lend the Company up to $5 million at an interest rate of 12% per
annum, $1.1 million of which was loaned to the Company on March 13, 1998 (the
"Loan") and (ii) Guaranty Finance purchased from the Company for $1,250 a
warrant to purchase 125,000 shares of the Company's Common Stock at a purchase
price of $8.00 per share. The Company has an option to repurchase up to 62,500
shares dependent on the level of borrowings over the term of the financing
arrangement. The warrant is exercisable through March 1, 2003. The Company paid
a $100,000 fee to Guaranty Finance in consideration for entering into the
aforementioned loan transaction. The Loan agreement expires on December 31, 1998
at which time any outstanding borrowings must be repaid.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
    
 
     The Registrant's Certificate of Incorporation provides that directors of
the Registrant shall not be personally liable to the Registrant or its
stockholders for monetary damages for breach of fiduciary duty as a director, to
the fullest extent permitted by the General Corporation Law of the State of
Delaware. The Registrant's Bylaws provide for indemnification of officers and
directors to the full extent and in the manner permitted by Delaware law.
Section 145 of the Delaware General Corporation Law makes provision for such
indemnification in terms sufficiently broad to cover officers and directors
under certain circumstances for liabilities arising under the Securities Act of
1933, as amended (the "Securities Act").
 
     The Registrant intends to enter into indemnification agreements with each
director and certain executive officers which provide indemnification under
certain circumstances for acts and omissions which may not be covered by any
directors' and officers' liability insurance.
 
     The form of Underwriting Agreement, filed as Exhibit 1.1 to the
Registration Statement, provides for indemnification of the Registrant and its
controlling persons against certain liabilities under the Securities Act.

ITEM 17. UNDERTAKINGS
 
     A. The Registrant hereby undertakes to provide to the underwriters at the
closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.
 
     B. Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers, and controlling persons of the
Registrant pursuant to the provisions described in Item 14 above, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question of whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
 
     C. The Registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities
     Act, the information omitted from the form of prospectus filed as part of
     this registration statement in reliance upon Rule 430A and contained in a
     form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     registration statement as of the time it was declared effective.
 
          (2) For purposes of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of prospectus shall
     be deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.

                          CERTIFICATE OF INCORPORATION
                                       OF
                        FIRST VIRTUAL MERGER CORPORATION


                                       I.

           The name of the corporation is:

                        First Virtual Merger Corporation

                                       II.

           The address of the registered office of the corporation in the State
of Delaware is 9 East Loockerman Street, City of Dover, County of Kent, and the
name of the registered agent of the corporation in the State of Delaware at such
address is National Registered Agents, Inc.

                                      III.

           The purpose of the corporation is to engage in any lawful act or
activity for which a corporation may be organized under the General Corporation
Law of the State of Delaware.

                                       IV.

           A. This corporation is authorized to issue two classes of stock to be
designated, respectively, Preferred Stock ("Preferred Stock") and Common Stock
("Common Stock"). The total number of shares of capital stock this corporation
shall have authority to issue is Forty Million (40,000,000). The total number of
shares of Preferred Stock this corporation shall have authority to issue is Ten
Million (10,000,000). The total number of shares of Common Stock this
corporation shall have authority to issue is Thirty Million (30,000,000). The
Preferred Stock and the Common Stock each shall have a par value of one tenth of
one cent ($.001) per share.

           B. Four Million (4,000,000) of the authorized shares of Preferred
Stock are hereby designated "Series A Preferred Stock" (the "Series A
Preferred"). Two Million Two Hundred Thousand (2,200,000) of the authorized
shares of Preferred Stock are hereby designated "Series B Preferred Stock" (the
"Series B Preferred"). One Million Three Hundred Seventy-Five Thousand
(1,375,000) of the authorized shares of Preferred Stock are hereby designated
"Series C Preferred Stock" (the "Series C Preferred"). Six Hundred Eighty-Seven
Thousand Five Hundred (687,500) of the authorized shares of Preferred Stock are
hereby designated "Series D Preferred Stock" (the "Series D Preferred"). The
Series A Preferred, Series B Preferred, Series C Preferred, and Series D
Preferred are collectively referred to as the "Series A, B, C, and D Preferred."




                                       1.
<PAGE>   2

           The remaining shares of Preferred Stock may be issued from time to
time in one or more series. The Board of Directors of the corporation (the
"Board of Directors") is expressly authorized to provide for the issue of all or
any of the remaining shares of the Preferred Stock in one or more series, and to
fix the number of shares and to determine or alter for each such series, such
voting powers, full or limited, or no voting powers, and such designations,
preferences, and relative, participating, optional, or other rights and such
qualifications, limitations, or restrictions thereof, as shall be stated and
expressed in the resolution or resolutions adopted by the Board of Directors
providing for the issue of such stock (a "Preferred Stock Designation") and as
may be permitted by the Delaware General Corporation Law. The Board of Directors
is also expressly authorized to increase or decrease (but not below the number
of shares of such series then outstanding) the number of shares of any series,
including the Series A Preferred, Series B Preferred, Series C Preferred, and
Series D Preferred, within the limits set forth above, subsequent to the issue
of shares of that series. In case the number of shares of any such series shall
be so decreased, the stock constituting such decrease shall resume the status
that it had prior to the adoption of the resolution originally fixing the number
of shares of such series.

           C. The powers, preferences, rights, restrictions, and other matters
relating to the Series A, B, C, and D Preferred are as follows:

               1.   DIVIDENDS.

                    (a) The holders of Series A, B, C, and D Preferred shall be
entitled to receive dividends at the rate of (i) with respect to the Series A
Preferred, $0.05 per share (as adjusted for any stock dividends, combinations or
splits with respect to such stock) per annum, payable out of funds legally
available therefor, (ii) with respect to the Series B Preferred, $0.15 per share
(as adjusted for any stock dividends, combinations or splits with respect to
such stock) per annum, payable out of funds legally available therefor, (iii)
with respect to the Series C Preferred, $0.40 per share (as adjusted for any
stock dividends, combinations or splits with respect to such stock) per annum,
payable out of funds legally available therefor, and (iv) with respect to the
Series D Preferred, $0.80 per share (as adjusted for any stock dividends,
combinations or splits with respect to such stock) per annum, payable out of
funds legally available therefor. Such dividends shall be payable only when, as,
and if declared by the Board of Directors and shall be noncumulative.

           No dividends (other than those payable solely in the Common Stock of
the corporation) shall be paid on any Common Stock of the corporation during any
fiscal year of the corporation until dividends at the aforesaid rates (as
adjusted for any stock dividends, combinations or splits with respect to such
shares) on the Series A, B, C, and D Preferred shall have been paid or declared
and set apart during that fiscal year, and no dividends shall be paid on any
share of Common Stock unless a dividend (including the amount of any dividends
paid pursuant to the above provisions of this Section C. 1) is paid with respect
to all outstanding shares of Series A, B, C, and D Preferred in an amount for
each such share of Series A, B, C, and D Preferred equal to or greater than the
aggregate amount of such dividends for all shares of Common Stock into which
each such share of Series A, B, C, and D Preferred could then be converted.



                                       2.

<PAGE>   3

           No right shall accrue to holders of Series A, B, C, and D Preferred
by reason of the fact that dividends on said stock are not declared in any prior
year, nor shall any undeclared or unpaid dividend bear or accrue any interest.

                    (b) In the event the corporation shall declare a
distribution (other than any distribution described in Section C.2 or C.4)
payable in securities of other persons, evidences of indebtedness issued by the
corporation or other persons, assets (excluding cash dividends) or options or
rights to purchase any such securities or evidences of indebtedness, then, in
each such case the holders of Series A, B, C, and D Preferred shall be entitled
to a proportionate share of any such distribution as though the holders of
Series A, B, C, and D Preferred were the holders of the number of shares of
Common Stock of the corporation into which the respective shares of Series A, B,
C, and D Preferred are convertible as of the record date fixed for the
determination of the holders of Common Stock of the corporation entitled to
receive such distribution.

               2.   LIQUIDATION PREFERENCE.

                    (a) In the event of any liquidation, dissolution or winding
up of the corporation, whether voluntary or involuntary, the holders of the
Series A Preferred, the holders of Series B Preferred, the holders of Series C
Preferred, and the holders of Series D Preferred shall be entitled to receive,
prior and in preference to any distribution of any of the assets or surplus
funds of the corporation to the holders of the Common Stock by reason of their
ownership thereof and in proportion to the liquidation preference of any other
outstanding series of Preferred Stock, the amount of $0.50 (the "Series A
Original Issue Price"), $1.50 (the "Series B Original Issue Price"), $4.00 (the
"Series C Original Issue Price"), and $8.00 (the "Series D Original Issue
price"), respectively (as adjusted for any stock dividends, combinations or
splits with respect to such stock), plus all accrued or declared but unpaid
dividends on such stock for each share of Series A, B, C, and D Preferred then
held by such holders. If upon the occurrence of such event, the assets and funds
thus distributed among the holders of Series A, B, C, and D Preferred shall be
insufficient to permit the payment to such holders of the full aforesaid
preferential amount, then the entire assets and funds of the corporation legally
available for distribution shall be distributed ratably among the holders of
Series A, B, C, and D Preferred in proportion to the preferential amount each
such holder is otherwise entitled to receive.

                    (b) After payment to the holders of Series A, B, C, and D
Preferred of the amounts set forth in Section C.2(a) above, the entire remaining
assets and funds of the corporation legally available for distribution, if any,
shall be distributed among the holders of the Common Stock and Series A, B, C,
and D Preferred in proportion to the shares of Common Stock then held by them
and the shares of Common Stock which they then have the right to acquire upon
conversion of the shares of Series A, B, C, and D Preferred then held by them,
up to a total return to the holders of Series A Preferred, Series B Preferred,
Series C Preferred, and Series D Preferred of two times the Series A Original
Issue Price, Series B Original Issue Price, Series C Original Issue Price, and
Series D Original Issue Price, respectively.





                                       3.
<PAGE>   4

                    (c) For purposes of this Section C.2, (i) any acquisition
of the corporation by means of merger or other form of corporate reorganization
in which outstanding stock of the corporation is exchanged for securities or
other consideration issued, or caused to be issued, by the acquiring corporation
or its subsidiary (other than a mere reincorporation transaction) or (ii) a sale
of all or substantially all of the assets of the corporation, shall be treated
as a liquidation, dissolution or winding up of the corporation and shall entitle
the holders of Series A, B, C, and D Preferred and Common Stock to receive at
the closing in cash, securities or other property (valued as provided in Section
C.2(d) below) amounts as specified in Sections C.2(a) and C.2(b) above.

                    (d) Whenever the distribution provided for in this
Section C.2 shall be payable in securities or property other than cash, the
value of such distribution shall be the fair market value of such securities or
other property.

               3.   VOTING RIGHTS; DIRECTORS.

                    (a) Each holder of shares of Series A, B, C, and D
Preferred shall be entitled to the number of votes equal to the number of shares
of Common Stock into which such shares of Series A, B, C, and D Preferred could
be converted and shall have voting rights and powers equal to the voting rights
and powers of the Common Stock (except as otherwise expressly provided herein or
as required by law, voting together with the Common Stock as a single class) and
shall be entitled to notice of any stockholders' meeting in accordance with the
Bylaws of the corporation. Fractional votes shall not, however, be permitted and
any fractional voting rights resulting from the above formula (after aggregating
all stock into which shares of Series A, B, C, and D Preferred held by each
holder could be converted) shall be rounded to the nearest whole number (with
one-half being rounded upward). Each holder of Common Stock shall be entitled to
one (1) vote for each share of Common Stock held.

                    (b) In addition to any other vote or consent required
herein or by law, the vote or written consent of the holders of at least
two-thirds (2/3) of the outstanding shares of Series A Preferred shall be
necessary for any amendment, alteration, or repeal of any provision of the
Articles of Incorporation or the Bylaws of the Company (including any filing of
a Certificate of Determination), that affects adversely the voting powers,
preferences, or other special rights or qualifications, limitations, or
restrictions of the Series A Preferred.

                    (c) In addition to any other vote or consent required
herein or by law, the vote or written consent of the holders of at least
two-thirds (2/3) of the outstanding shares of Series B Preferred shall be
necessary for any amendment, alteration, or repeal of any provision of the
Articles of Incorporation or the Bylaws of the Company (including any filing of
a Certificate of Determination), that affects adversely the voting powers,
preferences, or other special rights or qualifications, limitations, or
restrictions of the Series B Preferred.

                    (d) In addition to any other vote or consent required
herein or by law, the vote or written consent of the holders of at least
two-thirds (2/3) of the outstanding shares of Series C Preferred shall be
necessary for any amendment, alteration, or repeal of any provision of the
Articles of Incorporation or the Bylaws of the Company (including any filing





                                       4.
<PAGE>   5
of a Certificate of Determination), that affects adversely the voting powers,
preferences, or other special rights or qualifications, limitations, or
restrictions of the Series C Preferred.

                    (e) In addition to any other vote or consent required
herein or by law, the vote or written consent of the holders of at least
two-thirds (2/3) of the outstanding shares of Series D Preferred shall be
necessary for any amendment, alteration, or repeal of any provision of the
Articles of Incorporation or the Bylaws of the Company (including any filing of
a Certificate of Determination), that affects adversely the voting powers,
preferences, or other special rights or qualifications, limitations, or
restrictions of the Series D Preferred.

               4.   CONVERSION. The holders of Series A, B, C, and D Preferred
shall have conversion rights as follows (the "Conversion Rights"):

                    (a) RIGHT TO CONVERT. Each share of Series A Preferred,
Series B Preferred, Series C Preferred, and Series D Preferred shall be
convertible, at the option of the holder thereof, at any time after the date of
issuance of such share, at the office of the corporation or any transfer agent
for such stock, into such number of fully paid and nonassessable shares of
Common Stock as is determined by dividing the Series A Original Issue Price,
Series B Original Issue Price, Series C Original Issue Price, and Series D
Original Issue Price, respectively, by the Conversion Price applicable to the
Series A Preferred, Series B Preferred, Series C Preferred, and Series D
Preferred, respectively, determined as hereinafter provided, in effect on the
date the certificate is surrendered for conversion. The price at which shares of
Common Stock shall be deliverable upon conversion of shares of Series A
Preferred (the "Series A Conversion Price") shall initially be $0.50 per share
of Common Stock. The price at which shares of Common Stock shall be deliverable
upon conversion of shares of Series B Preferred (the "Series B Conversion
Price") shall initially be $1.50 per share of Common Stock. The price at which
shares of Common Stock shall be deliverable upon conversion of shares of Series
C Preferred (the "Series C Conversion Price") shall initially be $4.00 per share
of Common Stock. The price at which shares of Common Stock shall be deliverable
upon conversion of shares of Series D Preferred (the "Series D Conversion
Price") shall initially be $8.00 per share of Common Stock. Such initial Series
A Conversion Price, Series B Conversion Price, and Series C Conversion Price,
and Series D Conversion Price shall be adjusted as hereinafter provided.

                    (b) AUTOMATIC CONVERSION. Each share of Series A Preferred,
Series B Preferred, Series C Preferred, and Series D Preferred shall
automatically be converted into shares of Common Stock at the then-effective
Series A Conversion Price, Series B Conversion Price, Series C Conversion Price,
and Series D Conversion Price, respectively, upon the earlier of (i) the date
specified by vote or written consent or agreement of holders of at least
two-thirds (2/3) of the shares of such series then outstanding, or (ii)
immediately upon the closing of the sale of the corporation's Common Stock in a
firm commitment, underwritten public offering registered under the Securities
Act of 1933, as amended (the "Securities Act"), other than a registration
relating solely to a transaction under Rule 145 under such Act (or any successor
thereto) or to an employee benefit plan of the corporation, at a public offering
price (prior to underwriters' discounts and expenses) equal to or exceeding
$8.00 per share of Common Stock (as adjusted for any stock dividends,
combinations or splits with respect to such stock) and the






                                       5.
<PAGE>   6

aggregate proceeds to the corporation and/or any selling stockholders (after
deduction for underwriters' discounts) of which exceed $10,000,000.

                    (c) MECHANICS OF CONVERSION.

                         (i) Before any holder of Series A, B, C, or D
Preferred shall be entitled to convert the same into shares of Common Stock,
such holder shall surrender the certificate or certificates therefor, duly
endorsed, at the office of the corporation or of any transfer agent for such
stock, and shall give written notice to the corporation at such office that such
holder elects to convert the same and shall state therein the name or names in
which such holder wishes the certificate or certificates for shares of Common
Stock to be issued. The corporation shall, as soon as practicable thereafter,
issue and deliver at such office to such holder of Series A, B, C, or D
Preferred, a certificate or certificates for the number of shares of Common
Stock to which such holder shall be entitled as aforesaid. Such conversion shall
be deemed to have been made immediately prior to the close of business on the
date of surrender of the shares of Series A, B, C, or D Preferred to be
converted, and the person or persons entitled to receive the shares of Common
Stock issuable upon such conversion shall be treated for all purposes as the
record holder or holders of such shares of Common Stock on such date.

                         (ii) If the conversion is in connection with an
underwritten offering of securities pursuant to the Securities Act, the
conversion may, at the option of any holder tendering shares of Series A, B, C,
or D Preferred for conversion, be conditioned upon the closing with the
underwriters of the sale of securities pursuant to such offering, in which event
the person(s) entitled to receive the Common Stock upon conversion of Series A,
B, C, or D Preferred shall not be deemed to have converted such Series A, B, C,
or D Preferred until immediately prior to the closing of such sale of
securities.

                    (d) ADJUSTMENTS TO THE SERIES A CONVERSION PRICE, SERIES B
CONVERSION PRICE, SERIES C CONVERSION PRICE, AND SERIES D CONVERSION PRICE FOR
CERTAIN DILUTING ISSUES.

                         (i) SPECIAL DEFINITIONS. For purposes of this
Section C.4(d), the following definitions apply:

                             (1) "Option" shall mean rights, options, or
         warrants to subscribe for, purchase or otherwise acquire either Common
         Stock or Convertible Securities (defined below).

                             (2) "Original Issue Date" shall mean the date on
         which a share of Series D Preferred Stock was first issued.

                             (3) "Convertible Securities" shall mean any
         evidences of indebtedness, shares (other than Common Stock, Series A,
         Series B, Series C, and Series D Preferred) or other securities
         convertible into or exchangeable for Common Stock.




                                       6.
<PAGE>   7

                             (4) "Additional Shares of Common Stock" shall mean
         all shares of Common Stock issued (or, pursuant to Section C.4(d)(iii),
         deemed to be issued) by the corporation after the Original Issue Date,
         other than shares of Common Stock issued or issuable:

                                 (A) upon conversion of shares of Series A, B, 
         C, and D Preferred;

                                 (B) to officers, directors or employees of, or
         consultants to, the corporation pursuant to stock option or stock
         purchase plans or agreements on terms approved by the Board of
         Directors;

                                 (C) to leasing companies or financial 
         institutions providing leasing or debt financing to the Company, but
         not exceeding 200,000 shares of Common Stock, subject to adjustment for
         all subdivisions and combinations;

                                 (D) as a dividend or distribution on Series
         A, B, C, and D Preferred; or

                                 (E) for which adjustment of the Series A
         Conversion Price, Series B Conversion Price, Series C Conversion Price,
         and Series D Conversion Price is made pursuant to Section C.4(e).

                         (ii) NO ADJUSTMENT OF THE SERIES A CONVERSION PRICE,
SERIES B CONVERSION PRICE, SERIES C CONVERSION PRICE, OR SERIES D CONVERSION
PRICE. Any provision herein to the contrary notwithstanding, no adjustment in
the Series A Conversion Price, the Series B Conversion Price, the Series C
Conversion Price or the Series D Conversion Price shall be made in respect of
the issuance of Additional Shares of Common Stock unless the consideration per
share (determined pursuant to Section C.4(d)(v) hereof) for an Additional Share
of Common Stock issued or deemed to be issued by the corporation is less than
the Series A Conversion Price, Series B Conversion Price, Series C Conversion
Price, or Series D Conversion Price, respectively, in effect on the date of, and
immediately prior to, such issue.

                        (iii) DEEMED ISSUE OF ADDITIONAL SHARES OF COMMON
STOCK. In the event the corporation at any time or from time to time after the
Original Issue Date shall issue any Options or Convertible Securities or shall
fix a record date for the determination of holders of any class of securities
then entitled to receive any such Options or Convertible Securities, then the
maximum number of shares (as set forth in the instrument relating thereto
without regard to any provisions contained therein designed to protect against
dilution) of Common Stock issuable upon the exercise of such Options or, in the
case of Convertible Securities and Options therefor, the conversion or exchange
of such Convertible Securities and Options therefor, the conversion or exchange
of such Convertible Securities, shall be deemed to be Additional Shares of
Common Stock issued as of the time of such issue or, in case such a record date
shall have been fixed, as of the close of business on such record date, provided
that in any such case in which Additional Shares of Common Stock are deemed to
be issued:




                                       7.
<PAGE>   8

                             (1) no further adjustments in the Conversion Price
         for the Series A, B, C, or D Preferred shall be made upon the
         subsequent issue of Convertible Securities or shares of Common Stock
         upon the exercise of such Options or conversion or exchange of such
         Convertible Securities;

                             (2) if such Options or Convertible Securities by
         their terms provide, with the passage of time or otherwise, for any
         increase or decrease in the consideration payable to the corporation,
         or decrease or increase in the number of shares of Common Stock
         issuable, upon the exercise, conversion or exchange thereof, the Series
         A Conversion Price, Series B Conversion Price, Series C Conversion
         Price, or Series D Conversion Price computed upon the original issue
         thereof (or upon the occurrence of a record date with respect thereto),
         and any subsequent adjustments based thereon, shall, upon any such
         increase or decrease becoming effective, be recomputed to reflect such
         increase or decrease insofar as it affects such Options or the rights
         of conversion or exchange under such Convertible Securities (provided,
         however, that no such adjustment of the Series A Conversion Price,
         Series B Conversion Price, Series C Conversion Price, or Series D
         Conversion Price shall affect Common Stock previously issued upon
         conversion of the Series A, B, C, or D Preferred);

                             (3) upon the expiration of any such Options or any
         rights of conversion or exchange under such Convertible Securities
         which shall not have been exercised, the Series A Conversion Price, the
         Series B Conversion Price, the Series C Conversion Price, and the
         Series D Conversion Price computed upon the original issue thereof (or
         upon the occurrence of a record date with respect thereto), and any
         subsequent adjustments based thereon, shall, upon such expiration, be
         recomputed as if:

                                 (A) in the case of Convertible Securities or
         Options for Common Stock, the only Additional Shares of Common Stock
         issued were the shares of Common Stock, if any, actually issued upon
         the exercise of such Options or the conversion or exchange of such
         Convertible Securities and the consideration received therefor was the
         consideration actually received by the corporation for the issue of all
         such Options, whether or not exercised, plus the consideration actually
         received by the corporation upon such exercise, or for the issue of all
         such Convertible Securities as the additional consideration, if any,
         actually received by the corporation upon such conversion or exchange;
         and

                                 (B) in the case of Options for Convertible
         Securities, only the Convertible Securities, if any, actually issued
         upon the exercise thereof were issued at the time of issue of such
         Options, and the consideration received by the corporation for the
         Additional Shares of Common Stock deemed to have been then issued was
         the consideration actually received by the corporation for the issue of
         all such Options, whether or not exercised, plus the consideration
         deemed to have been received by the corporation (determined pursuant to
         Section C.4(d)) upon the issue of the Convertible Securities with
         respect to which such Options were actually exercised;




                                       8.


<PAGE>   9

                             (4) no readjustment pursuant to clause (2) or (3)
         above shall have the effect of increasing the Series A Conversion
         Price, the Series B Conversion Price, the Series C Conversion Price, or
         the Series D Conversion Price to an amount which exceeds the lower of
         (a) the Series A Conversion Price, Series B Conversion Price, the
         Series C Conversion Price, or the Series D Conversion Price,
         respectively, on the original adjustment date, or (b) the Series A
         Conversion Price, Series B Conversion Price, Series C Conversion Price,
         or Series D Conversion Price, respectively, that would have resulted
         from any issuance of Additional Shares of Common Stock between the
         original adjustment date and such readjustment date;

                             (5) in the case of any Options which expire by
         their terms not more than 30 days after the date of issue thereof, no
         adjustment of the Series A Conversion Price, Series B Conversion Price,
         Series C Conversion Price, or Series D Conversion Price, shall be made
         until the expiration or exercise of all such Options, whereupon such
         adjustment shall be made in the same manner provided in clause (3)
         above.

                         (iv) ADJUSTMENT OF CONVERSION PRICE UPON ISSUANCE OF
ADDITIONAL SHARES OF COMMON STOCK. In the event this corporation, at any time
after the Original Issue Date, shall issue Additional Shares of Common Stock
(including Additional Shares of Common Stock deemed to be issued pursuant to
Section C.4(d)(iii)) without consideration or for a consideration per share less
than the Conversion Price for any series of Preferred Stock in effect on the
date of and immediately prior to such issue, then and in such event, the
Conversion Price for such series shall be reduced, concurrently with such issue,
to a price (calculated to the nearest cent) determined by multiplying the
Conversion Price for such series of Preferred Stock by a fraction, the numerator
of which shall be the number of shares of Common Stock outstanding immediately
prior to such issue plus the number of shares of Common Stock which the
aggregate consideration received by the corporation for the total number of
Additional Shares of Common Stock so issued would purchase at such Conversion
Price for such series of Preferred Stock in effect immediately prior to such
issuance, and the denominator of which shall be the number of shares of Common
Stock outstanding immediately prior to such issue plus the number of such
Additional Shares of Common Stock so issued. For the purpose of the above
calculation, the number of shares of Common Stock outstanding immediately prior
to such issue shall be calculated on a fully diluted basis, as if all shares of
Series A, B, C, and D Preferred and all Convertible Securities had been fully
converted into shares of Common Stock immediately prior to such issuance and any
outstanding Options had been fully exercised immediately prior to such issuance
(and the resulting securities fully convertible into shares of Common Stock, if
so convertible) as of such date, but not including in such calculation any
additional shares of Common Stock issuable with respect to shares of Series A,
B, C, and D Preferred, Convertible Securities, or outstanding Options, solely as
a result of the adjustment of the respective Conversion Prices (or other
conversion ratios) resulting from the issuance of the Additional Shares of
Common Stock causing the adjustment in question.

                         (v) DETERMINATION OF CONSIDERATION. For purposes of
this Section C.4(d), the consideration received by the corporation for the
issuance of any Additional Shares of Common Stock shall be computed as follows:




                                       9.
<PAGE>   10


                             (1) CASH AND PROPERTY. Such consideration shall:

                                 (A) Insofar as it consists of cash, be
         computed at the aggregate amount of cash received by the corporation
         excluding amounts paid or payable for accrued interest or accrued
         dividends;

                                 (B) insofar as it consists of property other
         than cash, be computed at the fair value thereof at the time of such
         issue, as determined in good faith by the Board of Directors; and

                                 (C) in the event Additional Shares of Common
         Stock are issued together with other stock or securities or other
         assets of the corporation for consideration which covers both, be the
         proportion of such consideration so received, computed as provided in
         clauses (A) and (B) above, as determined in good faith by the Board of
         Directors.

                             (2) OPTIONS AND CONVERTIBLE SECURITIES. The
         consideration per share received by the corporation for Additional
         Shares of Common Stock deemed to have been issued pursuant to Section
         C.4(d)(iii), relating to Options and Convertible Securities shall be
         determined by dividing:

                                 (A) the total amount, if any, received or
         receivable by the corporation as consideration for the issue of such
         Options or Convertible Securities, plus the minimum aggregate amount of
         additional consideration (as set forth in the instruments relating
         thereto, without regard to any provision contained therein designed to
         protect against dilution) payable to the corporation upon the exercise
         of such Options or the conversion or exchange of such Convertible
         Securities, or in the case of Options for Convertible Securities, the
         exercise of such Options for Convertible Securities and the conversion
         or exchange of such Convertible Securities by

                                 (B) the maximum number of shares of Common
         Stock (as set forth in the instruments relating thereto, without regard
         to any provision contained therein designed to protect against the
         dilution) issuable upon the exercise of such Options or conversion or
         exchange of such Convertible Securities.

                    (e) ADJUSTMENTS TO CONVERSION PRICES FOR STOCK DIVIDENDS
AND FOR COMBINATIONS OR SUBDIVISIONS OF COMMON STOCK. In the event that this
corporation at any time or from time to time after the Original Issue Date shall
declare or pay, without consideration, any dividend on the Common Stock payable
in Common Stock or in any right to acquire Common Stock for no consideration, or
shall effect a subdivision of the outstanding shares of Common Stock into a
greater number of shares of Common Stock (by stock split, reclassification or
otherwise than by payment of a dividend in Common Stock or in any right to
acquire Common Stock), or in the event the outstanding shares of Common Stock
shall be combined or consolidated, by reclassification or otherwise, into a
lesser number of shares of Common Stock, then the Conversion Price for any
series of Preferred Stock in effect immediately prior to such event shall,
concurrently with the effectiveness of such event, be proportionately decreased
or 






                                      10.
<PAGE>   11

increased, as appropriate. In the event that this corporation shall declare or
pay, without consideration, any dividend on the Common Stock payable in any
right to acquire Common Stock for no consideration, then the corporation shall
be deemed to have made a dividend payable in Common Stock in an amount of shares
equal to the maximum number of shares issuable upon exercise of such rights to
acquire Common Stock.

                    (f) ADJUSTMENTS FOR RECLASSIFICATION AND REORGANIZATION. If
the Common Stock issuable upon conversion of Series A, B, C, or D Preferred
shall be changed into the same or a different number of shares of any other
class or classes of shares, whether by capital reorganization, reclassification
or otherwise (other than a subdivision or combination of shares provided for in
Section C.4(e) above or a merger or other reorganization referred to in Section
C.2(c) above), the Series A Conversion Price, the Series B Conversion Price, the
Series C Conversion Price, and the Series D Conversion Price then in effect
shall, concurrently with the effectiveness of such reorganization or
reclassification, be proportionately adjusted so that the Series A Preferred,
the Series B Preferred, the Series C Preferred, and the Series D Preferred,
respectively, shall be convertible into, in lieu of the number of shares of
Common Stock which the holders would otherwise have been entitled to receive, a
number of shares of such other class or classes of stock equivalent to the
number of shares of Common Stock that would have been subject to receipt by the
holders upon conversion of the Series A Preferred, Series B Preferred, Series C
Preferred, and Series D Preferred, respectively, immediately before that change.

                    (g) NO IMPAIRMENT. The corporation will not, by amendment
of its Articles of Incorporation or through any reorganization, transfer of
assets, consolidation, merger, dissolution, issue or sale of securities or any
other voluntary action, avoid or seek to avoid the observance or performance of
any of the terms to be observed or performed hereunder by the corporation, but
will at all times in good faith assist in the carrying out of all the provisions
of this Section C.4 and in the taking of all such action as may be necessary or
appropriate in order to protect the Conversion Rights of the holders of Series
A, B, C, and D Preferred against impairment.

                    (h) CERTIFICATE AS TO ADJUSTMENTS. Upon the occurrence of
each adjustment or readjustment of any Conversion Price pursuant to this Section
C.4, the corporation at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and prepare and furnish to each
holder of Series A, B, C, and D Preferred a certificate executed by the
corporation's Chief Executive Officer or Chief Financial Officer setting forth
such adjustment or readjustment and showing in detail the facts upon which such
adjustment or readjustment is based. The corporation shall, upon the written
request at any time of any holder of Series A, B, C, and D Preferred, furnish or
cause to be furnished to such holder a like certificate setting forth (i) such
adjustments and readjustments, (ii) the Conversion Price for such series at the
time in effect, and (iii) the number of shares of Common Stock and the amount,
if any, of other property which at the time would be received upon the
conversion of such series.

                    (i) NOTICES OF RECORD DATE. In the event that the
corporation shall propose at any time: (i) to declare any dividend or
distribution upon its Common Stock, whether





                                      11.
<PAGE>   12

in cash, property, stock or other securities, whether or not a regular cash
dividend and whether or not out of earnings or earned surplus; (ii) to offer for
subscription pro rata to the holders of any class or series of its stock any
additional shares of stock of any class or series or other rights; (iii) to
effect any reclassification or recapitalization of its Common Stock outstanding
involving a change in the Common Stock; or (iv) to merge or consolidate with or
into any other corporation, or sell, lease or convey all or substantially all of
its assets, or to liquidate, dissolve or wind up; then, in connection with each
such event, the corporation shall send to the holders of Series A, B, C, and D
Preferred:

                             (1) at least twenty (20) days' prior written
         notice of the date on which a record shall be taken for such dividend,
         distribution or subscription rights (and specifying the date on which
         the holders of Common Stock shall be entitled thereto) or for
         determining rights to vote, if any, in respect of the matters referred
         to in (iii) and (iv) above; and

                             (2) in the case of the matters referred to in 
         (iii) and (iv) above, at least twenty (20) days' prior written notice
         of the date when the same shall take place (and specifying the date on
         which the holders of Common Stock shall be entitled to exchange their
         Common Stock for securities or other property deliverable upon the
         occurrence of such event).

                    (j) ISSUE TAXES. The corporation shall pay any and all
issue and other taxes that may be payable in respect of any issue or delivery of
shares of Common Stock on conversion of Series A, B, C, and D Preferred pursuant
hereto; provided, however, that the corporation shall not be obligated to pay
any transfer taxes resulting from any transfer requested by any holder in
connection with any such conversion.

                    (k) RESERVATION OF SHARES ISSUABLE UPON CONVERSION. The
corporation shall at all times reserve and keep available out of its authorized
but unissued shares of Common Stock, solely for the purpose of effecting the
conversion of the shares of the Series A, B, C, and D Preferred, such number of
its shares of Common Stock as shall from time to time be sufficient to effect
the conversion of all outstanding shares of Series A, B, C, and D Preferred; and
if at any time the number of authorized but unissued shares of Common Stock
shall not be sufficient to effect the conversion of all then outstanding shares
of Series A, B, C, and D Preferred, the corporation will take such corporate
action as may, in the opinion of its counsel, be necessary to increase its
authorized but unissued shares of Common Stock to such number of shares as shall
be sufficient for such purpose, including, without limitation, engaging in best
efforts to obtain the requisite stockholder approval of any necessary amendment
to this Certificate of Incorporation.

                    (l) FRACTIONAL SHARES. No fractional share shall be issued
upon the conversion of any share or shares of Series A, B, C, or D Preferred.
All shares of Common Stock (including fractions thereof) issuable upon
conversion of more than one share of Series A, B, C, or D Preferred by a holder
thereof shall be aggregated for purposes of determining whether the conversion
would result in the issuance of any fractional share. If, after the
aforementioned aggregation, the conversion would result in the issuance of a
fraction of a share





                                      12.
<PAGE>   13

of Common Stock, the corporation shall, in lieu of issuing any fractional share,
pay the holder otherwise entitled to such fraction a sum in cash equal to the
fair market value of such fraction on the date of conversion (as determined in
good faith by the Board of Directors).

                    (m) NOTICES. Any notice required by the provisions of this
Section C.4 to be given to the holders of shares of Series A, B, C, or D
Preferred shall be deemed given if deposited in the United States mail, postage
prepaid, or if sent by facsimile or delivered personally by hand or nationally
recognized courier addressed to each holder of record at such holder's address
or facsimile number appearing on the books of the corporation.

               5.   INCREASING COMMON STOCK.

                    The number of authorized shares of Common Stock may be
increased or decreased (but not below the number of shares of Common Stock then
outstanding) by an affirmative vote of the holders of a majority of the
outstanding shares of Common Stock of the corporation.

               6.   NO REISSUANCE OF SERIES A, B, C, AND D PREFERRED.

                    Any share or shares of Series A, B, C, and D Preferred
acquired by the corporation by reason of redemption, purchase, conversion or
otherwise shall be restored to the status of authorized but unissued shares of
Preferred Stock.


                                       V.

         A. For the management of the business and for the conduct of the
affairs of the corporation, and in further definition, limitation and regulation
of the powers of the corporation, of its directors and of its stockholders or
any class thereof, as the case may be, it is further provided that:

               (1) The management of the business and the conduct of the
affairs of the corporation shall be vested in its Board of Directors. The number
of directors which shall constitute the whole Board of Directors shall be fixed
exclusively by one or more resolutions adopted by the Board of Directors.

               (2) Subject to the rights of the holders of any series of
Preferred Stock to elect additional directors under specified circumstances,
following the closing of the initial public offering pursuant to an effective
registration statement under the Securities Act of 1933, as amended, covering
the offer and sale of Common Stock to the public (the "Initial Public
Offering"), the directors shall be divided into three classes designated as
Class I, Class II and Class III, respectively. Directors shall be assigned to
each class in accordance with a resolution or resolutions adopted by the Board
of Directors. At the first annual meeting of stockholders following the closing
of the Initial Public Offering, the term of office of the Class I directors
shall expire and Class I directors shall be elected for a full term





                                      13.
<PAGE>   14

of three years. At the second annual meeting of stockholders following the
closing of the Initial Public Offering, the term of office of the Class II
directors shall expire and Class II directors shall be elected for a full term
of three years. At the third annual meeting of stockholders following the
closing of the Initial Public Offering, the term of office of the Class III
directors shall expire and Class III directors shall be elected for a full term
of three years. At each succeeding annual meeting of stockholders, directors
shall be elected for a full term of three years to succeed the directors of the
class whose terms expire at such annual meeting.

           Notwithstanding the foregoing provisions of this Article, each
director shall serve until his successor is duly elected and qualified or until
his death, resignation or removal. No decrease in the number of directors
constituting the Board of Directors shall shorten the term of any incumbent
director.

               (3) Subject to the rights of the holders of any series of
Preferred Stock, the Board of Directors or any individual director may be
removed from office at any time (i) with cause by the affirmative vote of the
holders of a majority of the voting power of all the then-outstanding shares of
voting stock of the corporation, entitled to vote at an election of directors
(the "Voting Stock") or (ii) without cause by the affirmative vote of the
holders of at least sixty-six and two-thirds percent (66 2/3%) of the voting
power of all the then-outstanding shares of the Voting Stock.

               (4) Subject to the rights of the holders of any series of
Preferred Stock, any vacancies on the Board of Directors resulting from death,
resignation, disqualification, removal or other causes and any newly created
directorships resulting from any increase in the number of directors, shall,
unless the Board of Directors determines by resolution that any such vacancies
or newly created directorships shall be filled by the stockholders, except as
otherwise provided by law, be filled only by the affirmative vote of a majority
of the directors then in office, even though less than a quorum of the Board of
Directors, and not by the stockholders. Any director elected in accordance with
the preceding sentence shall hold office for the remainder of the full term of
the director for which the vacancy was created or occurred and until such
director's successor shall have been elected and qualified.

         B.    (1) Subject to paragraph (h) of Section 43 of the Bylaws, and
notwithstanding the fact that some lesser percentage may be specified law, the
Bylaws may be altered or amended or new Bylaws adopted by the affirmative vote
of at least sixty-six and two-thirds percent (66-2/3%) of the voting power of
all of the then-outstanding shares of the Voting Stock. The Board of Directors
shall also have the power to adopt, amend, or repeal Bylaws.

               (2) The directors of the corporation need not be elected by 
written ballot unless the Bylaws so provide.

               (3) No action shall be taken by the stockholders of the
corporation except at an annual or special meeting of stockholders called in
accordance with the Bylaws or by written consent of stockholders in accordance
with the Bylaws prior to the closing of the Initial Public Offering. Following
the closing of the Initial Public Offering no action shall be taken by the
stockholders by written consent.

<PAGE>   6

circumstances surrounding the proposed disposition, and (B) if reasonably

        THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
        SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD OR TRANSFERRED,
        ASSIGNED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER SUCH
        ACT OR UNLESS THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL OR OTHER
        EVIDENCE, SATISFACTORY TO THE COMPANY AND ITS COUNSEL, THAT SUCH

        THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED
        PURSUANT TO REGULATION S OF THE SECURITIES ACT OF 1933 AND MAY NOT BE
        SOLD, MORTGAGED, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED EXCEPT

unlegended certificates at the request of any Holder thereof if the Holder shall
have obtained an opinion, at such Holder's expense, of counsel (which counsel
may be counsel to the Company) reasonably acceptable to the Company to the
effect that the securities proposed to be disposed of may lawfully be so
disposed of without registration, qualification or legend.

                      (c) Each Regulation S Purchaser is aware that the Company
will, and the Company agrees that Company shall, to the extent required by
Regulation S, refuse to register any transfer of the Shares purchased by such
Purchaser that is not made in accordance with Regulation S.



                                       4.

<PAGE>   7
                      (d) Any legend endorsed on an instrument pursuant to
applicable state securities laws and the stop-transfer instructions with respect
to such securities shall be removed upon receipt by the Company of an order of
the appropriate blue sky authority authorizing such removal.

               1.3    REQUESTED REGISTRATION.

                      (a)    REQUEST FOR REGISTRATION.  If the Company shall 
receive from Initiating Holders at any time or times not earlier than the
earlier of (i) five years after the date of this Agreement or (ii) one year
after the effective date of the first registration statement filed by the
Company covering an underwritten offering of any of its securities to the
general public, a written request that the Company effect any registration with
respect to all or a part of the Registrable Securities having an aggregate
offering price, net of underwriting discounts and expenses, equal to or
exceeding $10.00 per share of Common Stock (as adjusted for any stock dividends,
combinations or splits with respect to such shares) and the aggregate proceeds
of which (after deduction for underwriter's discounts and expenses related to
the issuance) exceed $10,000,000 the Company will:

                             (i)    promptly give written notice of the proposed
registration to all other Holders; and

                             (ii) as soon as practicable, use its best efforts
to effect such registration (including, without limitation, filing
post-effective amendments, appropriate qualifications under applicable blue sky
or other state securities laws, and appropriate compliance with the Securities
Act) and as would permit or facilitate the sale and distribution of all or such
portion of such Registrable Securities as are specified in a written request
received by the Company within ten (10) days after such written notice from the
Company is mailed or delivered.

        The Company shall not be obligated to effect, or to take any action to
effect, any such registration pursuant to this Section 1.3:

                                    (A)     In any particular jurisdiction in 
which the Company would be required to execute a general consent to service of
process in effecting such registration, qualification, or compliance, unless the
Company is already subject to service in such jurisdiction and except as may be
required by the Securities Act;

                                    (B)     After the Company has initiated two 
such registrations pursuant to this Section 1.3(a) (counting for these purposes
only registrations which have been declared or ordered effective and pursuant to
which securities have been sold and registrations which have been withdrawn by
the Holders as to which the Holders have not elected to bear the Registration
Expenses pursuant to Section 1.5 hereof and would, absent such election, have
been required to bear such expenses);



                                       5.

<PAGE>   8

                                    (C) During the period starting with the date
sixty (60) days prior to the Company's good faith estimate of the date of filing
of, and ending on a date one hundred eighty (180) days after the effective date
of, a Company-initiated registration; provided that the Company is actively
employing in good faith all reasonable efforts to cause such registration
statement to become effective;

                                    (D) If the Initiating Holders propose to
dispose of shares of Registrable Securities which may be immediately registered
on Form S-3 pursuant to a request made under Section 1.6 hereof;

                                    (E) If the Initiating Holders do not request
that such offering be firmly underwritten by underwriters selected by the
Initiating Holders (subject to the consent of the Company, which consent will
not be unreasonably withheld); or

                                    (F)     If the Company and the Initiating 
Holders are unable to obtain the commitment of the underwriter described in
clause (E) above to firmly underwrite the offer.

                      (b) Subject to the foregoing clauses (A) through (F), the
Company shall file a registration statement covering the Registrable Securities
so requested to be registered as soon as practicable after receipt of the
request or requests of the Initiating Holders; provided, however, that if (i) in
the good faith judgment of the Board of Directors of the Company, such
registration would be seriously detrimental to the Company and the Board of
Directors of the Company concludes, as a result, that it is essential to defer
the filing of such registration statement at such time, and (ii) the Company
shall furnish to such Holders a certificate signed by the Chief Executive
Officer of the Company stating that in the good faith judgment of the Board of
Directors of the Company, it would be seriously detrimental to the Company for
such registration statement to be filed in the near future and that it is,
therefore, essential to defer the filing of such registration statement, then
the Company shall have the right to defer such filing (except as provided in
clause (C) above) for a period of not more than one hundred eighty (180) days
after the receipt of the request of the Initiating Holders, and, provided
further, that the Company shall not defer its obligation in this manner more
than once in any twelve-month period.

        The registration statement filed pursuant to the request of the
Initiating Holders may, subject to the provisions of Sections 1.3(b) and 1.14
hereof, include other securities of the Company, with respect to which
registration rights have been granted, and may include securities of the Company
being sold for the account of the Company.

                      (c) UNDERWRITING. The right of any Holder to registration
pursuant to Section 1.3 shall be conditioned upon such Holder's participation in
such underwriting and the inclusion of such Holder's Registrable Securities in
the underwriting (unless otherwise mutually agreed by a majority in interest of
the Initiating Holders and such Holder with respect to such participation and
inclusion) to the extent provided herein. A Holder may elect to include in such
underwriting all or a part of the Registrable Securities such Holder holds.



                                       6.

<PAGE>   9
                      (d) PROCEDURES. If the Company shall request inclusion in
any registration pursuant to Section 1.3 of securities being sold for its own
account, or if other persons shall request inclusion in any registration
pursuant to Section 1.3, the Initiating Holders shall, on behalf of all Holders,
offer to include such securities in the underwriting and may condition such
offer on their acceptance of the further applicable provisions of this Section 1
(including Section 1.13). The Company shall (together with all Holders and other
persons proposing to distribute their securities through such underwriting)
enter into an underwriting agreement in customary form with the representative
of the underwriter or underwriters selected for such underwriting by a majority
in interest of the Initiating Holders, which underwriters are reasonably
acceptable to the Company. Notwithstanding any other provision of this Section
1.3, if the representative of the underwriters advises the Initiating Holders in
writing that marketing factors require a limitation on the number of shares to
be underwritten, the number of shares to be included in the underwriting or
registration shall be allocated as set forth in Section 1.14 hereof. If a person
who has requested inclusion in such registration as provided above does not
agree to the terms of any such underwriting, such person shall be excluded
therefrom by written notice from the Company, the underwriter or the Initiating
Holders. Any Registrable Securities or other securities excluded or withdrawn
from such underwriting shall also be withdrawn from such registration. If shares
are so withdrawn from the registration and if the number of shares to be
included in such registration was previously reduced as a result of marketing
factors pursuant to this Section 1.3(d), then the Company shall offer to all
Holders who have retained rights to include securities in the registration the
right to include additional securities in the registration in an aggregate
amount equal to the number of shares so withdrawn, with such shares to be
allocated among such Holders requesting additional inclusion in accordance with
Section 1.14.

               1.4    COMPANY REGISTRATION.

                      (a)    If the Company shall determine to register any of
its securities either for its own account or the account of a security holder or
holders exercising their respective demand registration rights (other than
pursuant to Section 1.3 or 1.6 hereof), other than a registration relating
solely to employee benefit plans, or a registration relating solely to a Rule
145 transaction, or a registration on any registration form that does not permit
secondary sales, the Company will:

                             (i)    promptly give to each Holder written notice
thereof; and

                             (ii) use its best efforts to include in such
registration (and any related qualification under blue sky laws or other
compliance), except as set forth in Section 1.4(b) below, and in any
underwriting involved therein, all the Registrable Securities specified in a
written request or requests, made by any Holder and received by the Company
within ten (10) days after the written notice from the Company described in
clause (i) above is mailed or delivered by the Company. Such written request may
specify all or a part of a Holder's Registrable Securities.



                                       7.

<PAGE>   10
                      (b) UNDERWRITING. If the registration of which the Company
gives notice is for a registered public offering involving an underwriting, the
Company shall so advise the Holders as a part of the written notice given
pursuant to Section l.4(a)(i). In such event, the right of any Holder to
registration pursuant to this Section 1.4 shall be conditioned upon such
Holder's participation in such underwriting and the inclusion of such Holder's
Registrable Securities in the underwriting to the extent provided herein. All
Holders proposing to distribute their securities through such underwriting shall
(together with the Company and the other holders of securities of the Company
with registration rights to participate therein distributing their securities
through such underwriting) enter into an underwriting agreement in customary
form with the representative of the underwriter or underwriters selected by the
Company.

        Notwithstanding any other provision of this Section 1.4, if the
representative of the underwriters advises the Company in writing that marketing
factors require a limitation on the number of shares to be underwritten, the
representative may (subject to the limitations set forth below) exclude all
Registrable Securities from, or limit the number of Registrable Securities to be
included in, the registration and underwriting. The Company shall so advise all
Holders of securities requesting registration, and the number of shares of
securities that are entitled to be included in the registration and underwriting
shall be allocated first to the Company for securities being sold for its own
account and thereafter as set forth in Section 1.14. If any person does not
agree to the terms of any such underwriting, such person shall be excluded
therefrom by written notice from the Company or the underwriter. Any Registrable
Securities or other securities excluded or withdrawn from such underwriting
shall also be withdrawn from such registration.

        If shares are so withdrawn from the registration or if the number of
shares of Registrable Securities to be included in such registration was
previously reduced as a result of marketing factors, the Company shall then
offer to all persons who have retained the right to include securities in the
registration the right to include additional securities in the registration in
an aggregate amount equal to the number of shares so withdrawn, with such shares
to be allocated among the persons requesting additional inclusion in accordance
with Section 1.14 hereof.

               1.5 EXPENSES OF REGISTRATION. All Registration Expenses incurred
in connection with any registration, qualification or compliance pursuant to
Sections 1.4 and 1.6 hereof, and the first two registrations pursuant to Section
1.3 hereof and reasonable fees of one counsel for the selling stockholders in
the case of registrations pursuant to Section 1.3 shall be borne by the Company;
provided, however, that if the Holders bear the Registration Expenses for any
registration proceeding begun pursuant to Section 1.3 and subsequently withdrawn
by the Holders registering shares therein, such registration proceeding shall
not be counted as a requested registration pursuant to Section 1.3 hereof.
Furthermore, in the event that a withdrawal by the Holders is based upon
material adverse information relating to the Company that is different from the
information known or available (upon request from the Company or otherwise) to
the Holders requesting registration at the time of their request for
registration under Section 1.3, such registration shall not be treated as a
counted registration for purposes of Section 1.3 hereof, even though the Holders
do not bear the Registration Expenses for such registration. All Selling
Expenses relating to securities so registered shall be borne by the



                                       8.

<PAGE>   11

Holders of such securities pro rata on the basis of the number of shares of
securities so registered on their behalf, as shall any other expenses in
connection with the registration required to be borne by the Holders of such
securities.

               1.6    REGISTRATION ON FORM S-3.

                      (a)    After its initial public offering, the Company 
shall use its best efforts to qualify for registration on Form S-3 or any
comparable or successor form or forms. After the Company has qualified for the
use of Form S-3, in addition to the rights contained in the foregoing provisions
of this Section 1, the Holders of Registrable Securities shall have the right to
request registrations on Form S-3 (such requests shall be in writing and shall
state the number of shares of Registrable Securities to be disposed of and the
intended methods of disposition of such shares by such Holder or Holders),
provided, however, that the Company shall not be obligated to effect any such
registration if (i) the Holders, together with the holders of any other
securities of the Company entitled to inclusion in such registration, propose to
sell Registrable Securities and such other securities (if any) on Form S-3 at an
aggregate price to the public of less than $1,000,000; or (ii) in the event that
the Company shall furnish the certification described in paragraph 1.3(b)(ii)
(but subject to the limitations set forth therein); or (iii) in a given
twelve-month period, the Company has effected one (1) such registration in such
period; or (iv) it is to be effected more than five (5) years after the
Company's initial public offering.

                      (b) If a request complying with the requirements of
Section 1.6(a) hereof is delivered to the Company, the provisions of Sections
1.3(a) and Section 1.3(b) hereof shall apply to such registration. If the
registration is for an underwritten offering, the provisions of Sections 1.3(c)
and 1.3(d) hereof shall apply to such registration.

               1.7 REGISTRATION PROCEDURES. In the case of each registration
effected by the Company pursuant to Section 1, the Company will keep each Holder
advised in writing as to the initiation of each registration and as to the
completion thereof. At its expense, the Company will use its best efforts to:

                      (a)    Keep such registration effective for a period of 
one hundred twenty (120) days or until the Holder or Holders have completed the
distribution described in the registration statement relating thereto, whichever
first occurs; provided, however, that (i) such 120-day period shall be extended
for a period of time equal to the period the Holder refrains from selling any
securities included in such registration at the request of an underwriter of
Common Stock (or other securities) of the Company; and (ii) in the case of any
registration of Registrable Securities on Form S-3 which are intended to be
offered on a continuous or delayed basis, such 120-day period shall be extended,
if necessary, to keep the registration statement effective until all such
Registrable Securities are sold, provided that Rule 145, or any successor rule
under the Securities Act, permits an offering on a continuous or delayed basis,
and provided further that applicable rules under the Securities Act governing
the obligation to file a post-effective amendment permit, in lieu of filing a
post-effective amendment that (I) includes any prospectus required by Section
10(a)(3) of the Securities Act or (II) reflects facts or events



                                       9.

representing a material or fundamental change in the information set forth in
the registration statement, the incorporation by reference of information
required to be included in (I) and (II) above to be contained in periodic
reports filed pursuant to Section 13 or 15(d) of the Exchange Act in the
registration statement;

                      (b) Prepare and file with the Commission 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 Securities Act with respect to the disposition of all
securities covered by such registration statement;

                      (c) Furnish such number of prospectuses and other
documents incident thereto, including any amendment of or supplement to the
prospectus, as a Holder from time to time may reasonably request;

                      (d) Cause all such Registrable Securities registered
pursuant hereunder to be listed on each securities exchange on which similar
securities issued by the Company are then listed;

                      (e) Provide a transfer agent and registrar for all
Registrable Securities registered pursuant to such registration statement and a
CUSIP number for all such Registrable Securities, in each case not later than
the effective date of such registration;

                      (f) Otherwise use its best efforts to comply with all
applicable rules and regulations of the Commission, and make available to its
security holders, as soon as reasonably practicable, an earnings statement
covering the period of at least twelve months, but not more than eighteen
months, beginning with the first month after the effective date of the
Registration Statement, which earnings statement shall satisfy the provisions of
Section 11(a) of the Securities Act; and

                      (g) In connection with any underwritten offering pursuant
to a registration statement filed pursuant to Section 1.3 hereof, the Company
will enter into an underwriting agreement in form reasonably necessary to effect
the offer and sale of Common Stock, provided such underwriting agreement
contains customary underwriting provisions and provided further that if the
underwriter so requests the underwriting agreement will contain customary
contribution provisions.

               1.8    INDEMNIFICATION.

                      (a)    The Company will indemnify each Holder, each of its
officers, directors and partners, legal counsel, and accountants and each person
controlling such Holder within the meaning of Section 15 of the Securities Act,
with respect to which registration, qualification, or compliance has been
effected pursuant to this Section 1, and each underwriter, if any, and each
person who controls within the meaning of Section 15 of the Securities Act any
underwriter, against all expenses, claims, losses, damages, and liabilities (or
actions, proceedings, or settlements in respect thereof) arising out of or based
on any untrue statement



                                       10.

<PAGE>   13

(or alleged untrue statement) of a material fact contained in any prospectus,
offering circular, or other document (including any related registration
statement, notification, or the like) incident to any such registration,
qualification, or compliance, or based on any omission (or alleged omission) to
state therein a material fact required to be stated therein or necessary to make
the statement therein not misleading, or any violation by the Company of the
Securities Act or any rule or regulation thereunder applicable to the Company
and relating to action or inaction required of the Company in connection with
any such registration, qualification, or compliance, and will reimburse each
such Holder, each of its officers, directors, partners, legal counsel, and
accountants and each person controlling such Holder, each such underwriter, and
each person who controls any such underwriter, for any legal and any other
expenses reasonably incurred in connection with investigating and defending or
settling any such claim, loss, damage, liability, or action, provided that the
Company will not be liable in any such case to the extent that any such claim,
loss, damage, liability, or expense arises out of or is based on any untrue
statement or omission based upon written information furnished to the Company by
such Holder or underwriter and stated to be specifically for use therein. It is
agreed that the indemnity agreement contained in this Section 1.8(a) shall not
apply to amounts paid in settlement of any such loss, claim, damage, liability,
or action if such settlement is effected without the consent of the Company
(which consent has not been unreasonably withheld).

                      (b) Each Holder will, if Registrable Securities held by
such Holder are included in the securities as to which such registration,
qualification, or compliance is being effected, indemnify the Company, each of
its directors, officers, partners, legal counsel, and accountants and each
underwriter, if any, of the Company's securities covered by such a registration
statement, each person who controls the Company or such underwriter within the
meaning of Section 15 of the Securities Act, each other such Holder and Other
Stockholder, and each of their officers, directors, and partners, and each
person controlling such Holder or Other Stockholder, against all claims, losses,
damages and liabilities (or actions in respect thereof) arising out of or based
on any untrue statement (or alleged untrue statement) of a material fact
contained in any such registration statement, prospectus, offering circular, or
other document, or any omission (or alleged omission) to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and will reimburse the Company and such Holders, Other
Stockholders, directors, officers, partners, legal counsel, and accountants,
persons, underwriters, or control persons for any legal or any other expenses
reasonably incurred in connection with investigating or defending any such
claim, loss, damage, liability, or action, in each case to the extent, but only
to the extent, that such untrue statement (or alleged untrue statement) or
omission (or alleged omission) is made in such registration statement,
prospectus, offering circular, or other document in reliance upon and in
conformity with written information furnished to the Company by such Holder and
stated to be specifically for use therein provided, however, that the
obligations of such Holder hereunder shall not apply to amounts paid in
settlement of any such claims, losses, damages, or liabilities (or actions in
respect thereof) if such settlement is effected without the consent of such
Holder (which consent shall not be unreasonably withheld); and provided that in
no event shall any indemnity under this Section 1.8 exceed the gross proceeds
from the offering received by such Holder.



                                       11.

<PAGE>   14

                      (c) Each party entitled to indemnification under this
Section 1.8 (the "Indemnified Party") shall give notice to the party required to
provide indemnification (the "Indemnifying Party") promptly after such
Indemnified Party has actual knowledge of any claim as to which indemnity may be
sought, and shall permit the Indemnifying Party to assume the defense of such
claim or any litigation resulting therefrom, provided that counsel for the
Indemnifying Party, who shall conduct the defense of such claim or any
litigation resulting therefrom, shall be approved by the Indemnified Party
(whose approval shall not unreasonably be withheld), and the Indemnified Party
may participate in such defense at such party's expense, and provided further
that the failure of any Indemnified Party to give notice as provided herein
shall not relieve the Indemnifying Party of its obligations under this Section
1, to the extent such failure is not prejudicial. No Indemnifying Party, in the
defense of any such claim or litigation, shall, except with the consent of each
Indemnified Party, consent to entry of any judgment or enter into any settlement
that does not include as an unconditional term thereof the giving by the
claimant or plaintiff to such Indemnified Party of a release from all liability
in respect to such claim or litigation. Each Indemnified Party shall furnish
such information regarding itself or the claim in question as an Indemnifying
Party may reasonably request in writing and as shall be reasonably required in
connection with defense of such claim and litigation resulting therefrom.

                      (d) If the indemnification provided for in this Section
1.8 is held by a court of competent jurisdiction to be unavailable to an
Indemnified Party with respect to any loss, liability, claim, damage, or expense
referred to therein, then the Indemnifying Party, in lieu of indemnifying such
Indemnified Party hereunder, shall contribute to the amount paid or payable by
such Indemnified Party as a result of such loss, liability, claim, damage, or
expense in such proportion as is appropriate to reflect the relative fault of
the Indemnifying Party on the one hand and of the Indemnified Party on the other
in connection with the statements or omissions that resulted in such loss,
liability, claim, damage, or expense as well as any other relevant equitable
considerations. The relative fault of the Indemnifying Party and of the
Indemnified Party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Indemnifying Party or by the Indemnified Party and the parties'
relative intent, knowledge, access to information, and opportunity to correct or
prevent such statement or omission.

                      (e)    Notwithstanding the foregoing, to the extent that
the provisions on indemnification and contribution contained in the underwriting
agreement entered into in connection with the underwritten public offering are
in conflict with the foregoing provisions, the provisions in the underwriting
agreement shall control.

               1.9 INFORMATION BY HOLDER. Each Holder of Registrable Securities
shall furnish to the Company such information regarding such Holder and the
distribution proposed by such Holder as the Company may reasonably request in
writing and as shall be reasonably required in connection with any registration,
qualification, or compliance referred to in this Section 1.



                                       12.

<PAGE>   15

               1.10 LIMITATIONS ON SUBSEQUENT REGISTRATION RIGHTS. From and
after the date of this Agreement, the Company shall not, without the prior
written consent of a majority in interest of the Holders, enter into any
agreement with any holder or prospective holder of any securities of the Company
giving such holder or prospective holder any registration rights the terms of
which are more favorable than the registration rights granted to the Holders
hereunder.

               1.11 RULE 144 REPORTING. With a view to making available the
benefits of certain rules and regulations of the Commission that may permit the
sale of the Restricted Securities to the public without registration, the
Company agrees to use its best efforts to:

                      (a)    Make and keep public information regarding the 
Company available as those terms are understood and defined in Rule 144 under
the Securities Act, at all times from and after ninety (90) days following the
effective date of the first registration under the Securities Act filed by the
Company for an offering of its securities to the general public;

                      (b) File with the Commission in a timely manner all
reports and other documents required of the Company under the Securities Act and
the Exchange Act at any time after it has become subject to such reporting
requirements;

                      (c) So long as a Holder owns any Restricted Securities,
furnish to the Holder forthwith upon written request a written statement by the
Company as to its compliance with the reporting requirements of Rule 144 (at any
time from and after ninety (90) days following the effective date of the first
registration statement filed by the Company for an offering of its securities to
the general public), and of the Securities Act and the Exchange Act (at any time
after it has become subject to such reporting requirements), a copy, of the most
recent annual or quarterly report of the Company, and such other reports and
documents so filed as a Holder may reasonably request in availing itself of any
rule or regulation of the Commission allowing a Holder to sell any such
securities without registration.

               1.12 TRANSFER OR ASSIGNMENT OF REGISTRATION RIGHTS. The rights to
cause the Company to register securities granted to a Holder by the Company
under this Section 1 may be transferred or assigned by a Holder only to a
transferee or assignee of not less than 50,000 shares of Registrable Securities
(as presently constituted and subject to subsequent adjustments for stock
splits, stock dividends, reverse stock splits, and the like), provided that the
Company is given written notice at the time of or within a reasonable time after
said transfer or assignment, stating the name and address of the transferee or
assignee and identifying the securities with respect to which such registration
rights are being transferred or assigned, and, provided further, that the
transferee or assignee of such rights assumes in writing the obligations of such
Holder under this Section 1.
                                                  
               1.13 "MARKET STAND-OFF" AGREEMENT. Each Holder hereby agrees
that such Holder shall not offer to sell, contract to sell or otherwise sell,
dispose of, loan, pledge or grant any rights with respect to (collectively, a
"Disposition") any shares of Common Stock, any options or warrants to purchase
any shares of Common Stock or any securities convertible into or exchangeable
for shares of Common Stock of the Company (collectively, "Securities") held by
such Holder (other than those included in the registration) for a period
specified by the representative of the underwriters of Common Stock (or other
securities) of the Company not to exceed one hundred eighty (180) days
following the effective date of a registration statement of the Company filed
under the Securities Act (the "Lock-Up Period"); provided that:

               (i) such agreement shall apply only to the Company's first such
registration statement; and

               (ii) all Holders and officers and directors of the Company enter
into similar agreements.

               The foregoing restriction is expressly agreed to preclude the
holder of the Securities from engaging in any hedging or other transaction that
is designed to or reasonably expected to lead to or result in a Disposition of
Securities during the Lock-Up Period even if such Securities would be disposed
of by someone other than the undersigned. Such prohibited hedging or other
transactions would include, without limitation, any short sale (whether or not
against the box) or any purchase, sale or grant of any right (including without
limitation any put or call option) with respect to any Securities or with
respect to any security (other than a broad-based market basket or index) that
includes, relates to or derives any significant part of its value from
Securities.

               Each Holder agrees to execute and deliver such other agreements
as may be reasonably requested by the Company or the underwriter which are
consistent with the foregoing or which are necessary to give further effect
thereto. In addition, if requested by the Company or the representative of the
underwriters of Common Stock (or other securities) of the Company, each Holder
shall provide, within ten (10) days of such request, such information as may be
required by the Company or such representative in connection with the
completion of any public offering of the Company's securities pursuant to a
registration statement filed under the Securities Act. The obligations
described in this Section 1.13 shall not apply to a registration relating
solely to employee benefit plans on Form S-1 or Form S-8 or similar forms that
may be promulgated in the future, or a registration relating solely to a
Commission Rule 145 transaction on Form S-4 or similar forms that may be
promulgated in the future. The Company may impose stop-transfer instructions
with respect to the shares of Common Stock (or other securities) subject to the
foregoing restriction until the end of said one hundred eighty (180) day period.

               1.14 ALLOCATION OF REGISTRATION OPPORTUNITIES. In any
circumstance in which all of the Registrable Securities and other shares of
Common Stock of the Company (including shares of Common Stock issued or issuable
upon conversion of shares of any currently unissued series of Preferred Stock of
the Company) with registration rights (the "Other Shares") requested to be
included in a registration on behalf of the Holders or other selling
stockholders cannot be so included as a result of limitations of the aggregate
number of shares of Registrable Securities and Other Shares that may be so
included, the number of shares of Registrable Securities and Other Shares that
may be so included shall be allocated among the Holders and other selling
stockholders requesting inclusion of shares pro rata on the basis of the number
of shares of Registrable Securities and Other Shares that would be held by such
Holders and other selling stockholders, assuming conversion; provided, however,
so that such allocation shall not operate to reduce the aggregate number of
Registrable Securities and Other Shares to be included in such registration, if
any Holder or other selling stockholder does not request inclusion of the
maximum number of shares of Registrable Securities and Other Shares allocated to
such person pursuant to the above-described procedure, the remaining portion of
such person's allocation shall be reallocated among those requesting Holders and
other selling stockholders whose allocations did not satisfy their requests pro
rata on the basis of the number of shares of Registrable Securities and Other
Shares which would be held by such Holders and other selling stockholders,
assuming conversion, and this procedure shall be repeated until all of the
shares of Registrable Securities and Other Shares which may be included in the
registration on behalf of the Holders and other selling stockholders have been
so allocated. The Company shall not limit the number of Registrable Securities
to be included in a registration pursuant to this Agreement in order to include
shares held by stockholders with no registration rights or to include founder's
stock or any other shares of stock issued to employees, officers, directors, or
consultants pursuant to the Company's 1993 Stock Purchase Plan except to the
extent necessary for the repayment of promissory notes issued to the Company by
holders of Common Stock issued to such holders under the 1993 Stock Purchase
Plan, or with respect to registrations under


                                       14.

<PAGE>   17

Section 1.6 hereof, in order to include in such registration securities
registered for the Company's own account.

               1.15 DELAY OF REGISTRATION. No Holder shall have any right to
take any action to restrain, enjoin, or otherwise delay any registration as the
result of any controversy that might arise with respect to the interpretation or
implementation of this Section 1.

               1.16   TERMINATION OF REGISTRATION RIGHTS.

                      (a)    Except as set forth in subparagraph (b) below, the 
right of any Holder to request registration or inclusion in any registration
pursuant to Section 1.3, 1.4 or 1.6 shall terminate on the closing of the first
Company initiated registered public offering of Common Stock of the Company, if
all shares of Registrable Securities held or entitled to be held upon conversion
by such Holder may immediately be sold under Rule 144 during any 90-day period,
or on such date after the closing of the first Company-initiated registered
public offering of Common Stock of the Company as all shares of Registrable
Securities held or entitled to be held upon conversion by such Holder may
immediately be sold under Rule 144 during any 90-day period.

                      (b) The provisions of subparagraph (a) shall not apply to
any Holder who owns more than two percent (2%) of the Company's outstanding
stock until the earlier of (i) such time as such Holder owns less than two
percent (2%) of the outstanding stock of the Company, or (ii) the expiration of
three years after the closing of the first registered public offering of Common
Stock of the Company.

        2. COVENANTS OF THE COMPANY.

               The Company hereby covenants and agrees, so long as any Holder
owns any Registrable Shares, as follows:

               2.1 BASIC FINANCIAL INFORMATION. The Company will furnish the
following reports to each Holder:

                      (a)    As soon as practicable after the end of each fiscal
year of the Company, and in any event within ninety (90) days thereafter, a
consolidated balance sheet of the Company and its subsidiaries, if any, as at
the end of such fiscal year, and consolidated statements of income and cash
flows of the Company and its subsidiaries, if any, for such year, prepared in
accordance with generally accepted accounting principles consistently applied
and setting forth in each case in comparative form the figures for the previous
fiscal year, all in reasonable detail and certified by independent public
accountants of recognized national standing selected by the Company, and a
Company-prepared comparison to the Company's operating plan for such year.

                      (b) As soon as practicable after the end of the first,
second, and third quarterly accounting periods in each fiscal year of the
Company, and in any event within



                                       15.

<PAGE>   18

forty-five (45) days thereafter, a consolidated balance sheet of the Company and
its subsidiaries, if any, as of the end of each such quarterly period, and
consolidated statements of income and cash flows of the Company and its
subsidiaries, if any, for such period and for the current fiscal year to date,
prepared in accordance with generally accepted accounting principles
consistently applied and setting forth in comparative form the figures for the
corresponding periods of the previous fiscal year and to the Company's operating
plan then in effect and approved by its Board of Directors, subject to changes
resulting from normal year-end audit adjustments, all in reasonable detail,
except that such financial statements need not contain the notes required by
generally accepted accounting principles.

               2.2    ADDITIONAL INFORMATION AND RIGHTS.

                      (a)    The Company will permit any Holder, so long as such
Holder (or its representative) owns at least 500,000 Shares, or such number of
shares of Common Stock issued upon conversion of 500,000 or more Shares, or any
combination thereof (as presently constituted and subject to subsequent
adjustment for stock splits, stock dividends, reverse stock splits,
recapitalizations and the like) and to each Holder which represents that it is a
"venture capital operating company" for purposes of Department of Labor
Regulation Section 2510.3-101, who requests them (a "Significant Holder") (or a
representative of any Significant Holder) to visit and inspect any of the
properties of the Company, including its books of account and other records (and
make copies thereof and take extracts therefrom), and to discuss its affairs,
finances and accounts with the Company's officers and its independent public
accountants, all at such reasonable times and as often as any such person may
reasonably request.

                      (b) The Company will deliver to each Significant Holder,
who so requests in writing, annually (and in any event no later than ten (10)
days after adoption by the Board of Directors of the Company) the financial plan
of the Company, in such manner and form as approved by the Board of Directors of
the Company, which financial plan shall include at least a projection of income
and a projected cash flow statement for each month in such fiscal year and a
projected balance sheet as of the end of each fiscal quarter in such fiscal
year. Any material changes in such business plan shall be delivered to each
Significant Holder as promptly as practicable after such changes have been
approved by the Board of Directors of the Company.

                      (c) The Company will deliver to each Significant Holder,
who so requests in writing, within thirty (30) days after the end of each month,
a consolidated balance sheet of the Company and its subsidiaries, if any, as at
the end of each month, and consolidated statements of income and cash flows of
the Company and its subsidiaries, if any, for such month.

                      (d) The provisions of Section 2.1 and this Section 2.2
shall not be in limitation of any rights which any Holder or Significant Holder
may have with respect to the books and records of the Company and its
subsidiaries, or to inspect their properties or discuss their affairs, finances
and accounts, under the laws of the jurisdictions in which they are
incorporated.



                                       16.

<PAGE>   19

                      (e) Anything in Section 2 to the contrary notwithstanding,
no Holder or Significant Holder by reason of this Agreement shall have access to
any trade secrets or classified information of the Company. Each Significant
Holder hereby agrees to hold in confidence and trust and not to misuse or
disclose any confidential information provided pursuant to this Section 2.2. The
Company shall not be required to comply with this Section 2.2 in respect of any
Holder whom the Company reasonably determines to be a competitor or an officer,
employee, director or greater than 10% stockholder of a competitor. For purposes
of this Section 2.2, AT&T Venture Company, L.P. ("AT&T Ventures") shall not be
considered a competitor of the Company; provided, however, that AT&T Ventures
hereby agrees not to disclose any confidential information of the Company to any
other person or entity.

                      (f) Each Holder who represents to the Company that such
Holder is a "venture capital operating company" for purposes of Department of
Labor Regulation Section 2510.3-101 shall in addition have the right to consult
with and advise the officers of the Company as to the management of the Company.

               2.3 TERMINATION OF RIGHTS. In lieu of the rights granted to
Holders under Section 2.2 of this Agreement, from the date the Company becomes
subject to the reporting requirements of the Exchange Act, the Company will
provide to any Holder who requests such in writing, copies of the Company's
annual reports on Form 10-K and quarterly reports on Form 10-Q.

        3.     MISCELLANEOUS.

               3.1 GOVERNING LAW. This Agreement shall be governed in all
respects by the laws of the State of California as applied to agreements among
California residents entered into and to be performed entirely within
California.

               3.2 SUCCESSORS AND ASSIGNS. Except as otherwise expressly
provided herein, the provisions hereof shall inure to the benefit of, and be
binding upon, the successors, assigns, heirs, executors and administrators of
the parties hereto.

               3.3 ENTIRE AGREEMENT; AMENDMENT; WAIVER. This Agreement
(including the Exhibits hereto) constitutes the full and entire understanding
and agreement between the parties with regard to the subjects hereof and
thereof. Neither this Agreement nor any term hereof may be amended, waived,
discharged or terminated, except by a written instrument signed by the Company
and the holders of at least fifty percent (50%) of the Registrable Securities
and any such amendment, waiver, discharge or termination shall be binding on all
the Holders, but in no event shall the obligation of any Holder hereunder be
materially increased, except upon the written consent of such Holder.

               3.4 ADDITIONAL SERIES C PURCHASERS. Any person who has purchased
or who purchases shares of the Company's Series C Preferred Stock pursuant to
the Company's 1996 Employee Stock Purchase Bonus Plan may execute a counterpart
copy of this Agreement and



                                       17.

<PAGE>   20

shall thereupon become an "Employee Shareholder" and an "Investor" under this
Agreement, and shall have the rights and obligations of an "Investor" hereunder
and thereunder.

               3.5 NOTICES, ETC. All notices and other communications required
or permitted hereunder shall be in writing and shall be mailed by first-class
mail, postage prepaid, sent by facsimile or delivered personally by hand or
nationally or internationally recognized courier (as the case may be) addressed
(a) if to a Holder, as indicated on the list of Holders attached hereto as
Exhibit A, Exhibit B, Exhibit C, Exhibit D, Exhibit E, or Exhibit F or at such
other address or facsimile number as such Holder or permitted assignee shall
have furnished to the Company in writing, or (b) if to the Company, at such
address or facsimile number as the Company shall have furnished to each Holder
in writing. All such notices and other written communications shall be effective
on the date of mailing, facsimile transfer or delivery.

               3.6 DELAYS OR OMISSIONS. No delay or omission to exercise any
right, power or remedy accruing to any Holder, upon any breach or default of the
Company under this Agreement shall impair any such right, power or remedy of
such Holder nor shall it be construed to be a waiver of any such breach or
default, or an acquiescence therein, or of or in any similar breach or default
thereafter occurring; nor shall any waiver of any single breach or default be
deemed a waiver of any other breach or default therefore or thereafter
occurring. Any waiver, permit, consent or approval of any kind or character on
the part of any Holder of any breach or default under this Agreement or any
waiver on the part of any Holder of any provisions or conditions of this
Agreement must be made in writing and shall be effective only to the extent
specifically set forth in such writing. All remedies, either under this
Agreement or by law or otherwise afforded to any Holder, shall be cumulative and
not alternative.

               3.7 RIGHTS; SEPARABILITY. Unless otherwise expressly provided
herein, a Holder's rights hereunder are several rights, not rights jointly held
with any of the other Holders. In case any provision of the Agreement shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

               3.8 INFORMATION CONFIDENTIAL. Each Holder acknowledges that the
information received by such Holder pursuant hereto may be confidential and for
such Holder's use only, and Holder will not use such confidential information in
violation of the Exchange Act or reproduce, disclose or disseminate such
information to any other person (other than its employees or agents having a
need to know the contents of such information, and its attorneys), except in
connection with the exercise of rights under this Agreement, unless the Company

video products in conjunction with IBM's ATM based hardware and services
offerings.

IBM shall have the right, but not the obligation, to refer customers to FVC or
recommend that FVC contact a particular customer in marketing situations where
IBM believes there may be a demand for a FVC video solution.

Each party shall sell their respective products pursuant to their own terms,
conditions and warranties. Neither party shall be considered an agent, reseller
or remarketer of the other party and neither party will make any statement or
representation to any customer or other third party that would imply or suggest
that the other party has any obligation to the customer concerning the selling
party's products.

2. COMPENSATION BY FVC

FVC by IBM or to customers where IBM recommended that FVC contact the customer
as set forth in Section 1 above FVC shall pay IBM as set forth below. For
purposes of this Section sales shall include follow-on sales made to the
customer for a period of [*] after the initial sale.
FVC shall pay IBM as follows:

Debtor hereby assigns and pledges to Secured Party, and hereby grants to Secured
Party a security interest in and to the Collateral to secure the payment and
performance of all financial obligations of Debtor to Secured Party, however and
whenever arising, including the Loan Obligations (the "Secured Obligations").

               Section 3.2  Security Interest Absolute.
All rights of Secured Party and security interests granted hereunder, and all
obligations of Debtor hereunder, shall be absolute and unconditional,
irrespective of:

    (i)      any lack of validity or enforceability of this Agreement or any of
             the other Related Documents;

    (ii)     any change in the time, manner or place of payment of, or in any
             other term of, all or any of the Secured Obligations, or any other

             Agreement or any other of the Related Documents, including, without
             limitation, any increase in the Secured Obligations resulting from
             the extension of additional credit to Debtor, or any of its
             Affiliates, or otherwise;

    (iii)    subject to compliance with applicable laws, any manner of

             manner of sale or other disposition of any Collateral for all or 
             any of the Secured Obligations or any other assets of Debtor or any
             of its Affiliates; and

under the Related Documents remain unfulfilled, (b) be binding upon Debtor, its
successors and assigns, and (c) inure to the benefit of, and be enforceable by,

any Related Documents with respect to such released Collateral.

               Section 3.4  Limited Authorization.
Debtor hereby authorizes Secured Party to file one or more financing statements,
filings, reports, security agreements or continuation statements in respect
thereof, and amendments thereto, relating to all or any part of the Collateral

as its attorney in fact and authorizes it, if an Event of Default has occurred
and is continuing, to execute any and all financing statements on Debtor's
behalf solely to the extent necessary or advisable to perfect, continue or give
notice of the security interest granted to Security Party hereunder in any of
the Collateral. A photocopy or other reproduction of this Agreement or any
financing statement covering the Collateral or any part thereof shall be
sufficient as a financing statement where permitted by law.

        SECTION 4.  REPRESENTATIONS AND WARRANTIES.
Debtor represents and warrants to Secured Party as of the date of this Agreement
the following:

               Section 4.1.  Capacity.
Debtor is duly organized, validly existing and in good standing under the laws
of the State of Delaware, and in every other state where failure to so qualify
is reasonably likely to have a MAE.. Debtor has full power, authority, and legal
right to own its properties and assets and to conduct its business as presently
conducted. Debtor does not have any Subsidiaries, other than First Virtual
Limited U.K.

               Section 4.2.  Authority.
Debtor has full power, authority and legal right to execute and deliver, and to
perform and observe the provisions of this Agreement and the Related Documents.
Debtor's execution, delivery and performance of this Agreement and the Related
Documents have been duly authorized by all necessary corporate action. When duly
executed and delivered by Debtor, this Agreement and the Related Documents will
be legal, valid, and binding obligations of Debtor enforceable in accordance
with their respective terms, except as enforceability may be limited by the
United States Bankruptcy Code, or other statutes affecting creditor's rights
generally or by general principles of equity.

               Section 4.3.  Compliance.
Debtor is not in material violation of, or in default under (i) any provision of
its certificate of incorporation, articles of incorporation, or bylaws, or (ii)
any material contract, instrument, indenture, judgment, order, writ or decree to
which it or any of its Subsidiaries is a party or by which it or any of them is
bound, or, to the best of its knowledge, of any provision of any federal or
state statute, rule or regulation applicable to the Debtor or any of its
Subsidiaries. 


- --------------------------------------------------------------------------------
                      Loan and Security Agreement, Page 6 
<PAGE>   7


The execution, delivery, and performance of this Agreement and the Related
Documents will not, with or without the passage of time and giving of notice,
result in any such material violation, conflict or default, or an event that
results in the creation of any material Lien, charge or encumbrance upon any
assets of the Debtor or any of its Subsidiaries or the suspension, revocation,
impairment or forfeiture of any material permit, license, authorization, or
approval applicable to the Debtor or any of its Subsidiaries which is reasonably
likely to have a MAE.

               Section 4.4.  Financial Statements.
The audited financial statements for Debtor for the nine months ending 9/30/97
and the unaudited financial statement for Debtor that Debtor for the period
ending 1/31/98 supplied to Secured fairly present Debtor's financial condition
as of the date of the statements. Such financial statements have been prepared
in accordance with GAAP, subject, in the case of unaudited financials, to
year-end audit adjustments and footnotes.

               Section 4.5.  Material Adverse Events.
Since the most recent financial statements provided to Secured Party by Debtor

tax returns which are required to be filed by it. Each of Debtor and any of its
Subsidiaries has paid all taxes which have or may have become due pursuant to
said returns or otherwise or pursuant to an assessment received by Debtor,
except such taxes, if any, as are being contested in good faith and as to which
reserves have been created on the books of Debtor in accordance with GAAP. The
charges, accruals, and reserves in respect of income taxes on the books of
Debtor are adequate. Debtor knows of no proposed tax assessment against it or
any of its Subsidiaries and no extension of time for the assessment of federal,
state, or local taxes of Debtor or any of its Subsidiaries is in effect or has
been requested, except as disclosed in the financial statements furnished to

               Section 4.7. Patents and Trademarks
To the best of its knowledge, Debtor has sufficient title and ownership of all
patents, copyrights, trade secrets, information, proprietary rights and
processes necessary for its business as now conducted without any conflict with
or infringement of the rights of others, except that no representations are made
with respect to noninfringement of patents not issued as of the date hereof or
to any exclusive rights to trade secrets or know-how of the Debtor. Except as
disclosed in the Audited Financial Statements (as defined in Section 6.1) for
Debtor supplied to Secured Party, other than such matters as have been settled,
the Debtor has not received any communications alleging that the Debtor has
violated or, by conducting its business as proposed, would violate any of the
patents, trademarks, service marks, tradenames, copyrights or trade secrets or
other proprietary rights of any other Person or entity, other than such
communication that would not result in a MAE.

               Section 4.8. Priority Interest in Collateral.
Debtor is the legal and beneficial owner of the Collateral free and clear of any
Lien, except for Permitted Liens. This Agreement together with the filing of
financing statements creates a valid perfected, security interest in the
Collateral subject only to Permitted Liens to the extent that a security
interest can be perfected by the filing of Uniform Commercial Code financing
statements.
               Section 4.9.  Location of Collateral.
All of the Collateral of Debtor is located at the Debtor's Locations, except
moveable Collateral that is in transit in the ordinary course of business.

               Section 4.10.  Hazardous Substances.
None of Debtor's properties or assets has ever been used by Debtor or, to the
best of Debtor's knowledge, by previous owners or operators in the disposal of,
or to produce, store, handle, treat, release, or transport, any hazardous waste
or hazardous substance other than in 


- --------------------------------------------------------------------------------
                      Loan and Security Agreement, Page 7 
<PAGE>   8

accordance with applicable law; to the best knowledge of Debtor none of Debtor's
properties or assets has ever been designated or identified in any manner
pursuant to any environmental protection statute as a hazardous waste or
hazardous substance disposal site, or a candidate for closure pursuant to any
environmental protection statute; no Lien arising under any environmental
protection statute has attached to any revenues or to any real or personal
property owned by Debtor; and Debtor has not received a summons, citation,
notice, or directive from the Environmental Protection Agency or any other
federal or state governmental agency concerning any action or omission by Debtor
resulting in the releasing, or otherwise disposing of hazardous waste or
hazardous substances into the environment.

               Section 4.11. Litigation; Compliance with Laws and Agreements.
There are no actions or proceedings pending, or to the knowledge of Debtor
threatened, against or affecting Debtor which, if adversely determined, could
have a MAE. Debtor is not in default with respect to any writ, the breach of
which may have an MAE.

               Section 4.12.  Full Disclosure.
No representation, warranty or other statement made by Debtor in any certificate
or written statement furnished to Secured Party contains any untrue statement of
a material fact or omits to state a material fact necessary in order to make the
statements contained in such certificates or statements not misleading in the
context made.

               Section 4.13.  Survival of Representation and Warranties.
Debtor understands and agrees that Secured Party is relying upon the above
representations and warranties in extending Loan advances to Debtor and each of
the above representations and warranties be true and correct as of the date of
each such extension, except as disclosed in writing to Secured Party from time
to time, provided however that if any exceptions have been disclosed to Secured
Party, Secured Party shall have no obligation to extend Loan advances to Debtor.

portion of the assets or business of Debtor.

               Section 6.5   Maintenance of Existence.

                              Landlord Waivers

perfect Secured Party's security interest in any Collateral located outside the
U.S., or perfect the registration of Intellectual Property outside of the U.S..
Debtor shall at all times defend Secured Party and the Collateral against all
claims of others, subject to Permitted Liens. Debtor is not and will not become
a lessee under any real property lease pursuant to which the lessor or any other
person may obtain any rights in any of the Collateral, other than Tenant
Improvements, and no such lease now prohibits, restrains, impairs or will
prohibit, restrain or impair Debtor's right to remove any Collateral, other than
Tenant Improvements, from the leased premises. Whenever any Collateral is
located upon premises in which any third party has an interest (whether as
owner, mortgagee, beneficiary under a deed of trust, lien or otherwise), Debtor
shall, if requested by Secured Party, use its best efforts to cause such third
party to execute and deliver to Secured Party, in form acceptable to Secured
Party, such waivers, consents, agreements and subordination's as Secured Party
shall specify. Debtor will keep in full force and effect, and will comply with
all the terms of, any lease of real property where any of the collateral now or
in the future may be located.

        SECTION 7.  NEGATIVE COVENANTS.
Debtor covenants and agrees that, without the prior written consent of Secured
Party, which may be withheld in Secured Party's sole discretion, so long as any
credit hereunder shall be available and until payment in full of the outstanding
Loan Obligations or for so long as Secured Party may have any commitment to make
any Loans, Secured Party will not do any of the following:

               Section 7.1   Indebtedness.
Create, incur, assume or be or remain liable with respect to any Indebtedness,
or permit any Subsidiary so to do, other than Permitted Indebtedness.

               Section 7.2   Liens.
Create, incur, assume or suffer to exist any Lien with respect to any of its
property, or assign or otherwise convey any right to receive income, including
the sale of any accounts, or permit any of its Subsidiaries so to do, except for
Permitted Liens.

               Section 7.3   Mergers or Acquisitions
Merge or consolidate with or into any other business organization, or acquire,
or permit any of its Subsidiaries to acquire, all or substantially all of the
capital stock or property of another Person; provided that this Section 7.3
shall not apply to (i) transactions among Debtor and its Subsidiaries in which
the Debtor is the surviving entity, (ii) mergers and acquisitions entered into
for the purpose of changing the Debtor's or any Subsidiary's jurisdiction of
incorporation and (iii) acquisitions, the purchase price for which consists
solely of capital stock or the cash portion of the purchase price for which does
not exceed Five Million dollars ($5,000,000), other than the purchase of stock
in a Subsidiary, but Debtor shall give Secured Party at least 20 days advance
written notice of any transaction in clause (i), (ii), or (iii) above and shall
execute and deliver all such documents and instruments and take all such actions
as are necessary to continue in effect Secured Party's first-priority, perfected

               Section 9.6  Secured Party's Duties.

interest in the Collateral and shall not impose any duty upon Secured Party to

This Agreement shall bind and inure to the benefit of the respective successors
and permitted assigns of each of the parties; provided, however, that neither
this Agreement nor any rights hereunder may be assigned by Debtor without

or more purchasers, or potential purchasers, any information or knowledge
Secured Party may have about Debtor or about any other matter relating to the
Loan, and Debtor hereby waives any rights to privacy it may have with respect to
such matters; provided such purchasers agree to the confidentiality provisions

interest, as well as all notices of any repurchase or such participation
interest in the Loans. Debtor further waives all rights of offset or
counterclaim that it may have now or later against Secured Party or against any
purchaser of a participation interest and unconditionally agrees that either
Secured Party or such purchaser may enforce Debtor's obligation under the Loan
irrespective of the failure or insolvency of any holder of any interest in the

enforce its interest irrespective of any personal claims or defenses that Debtor
may have against Secured Party. Any costs associated with the attempt to arrange
any such participation interest will be borne by Secured Party.

               Section 10.6  Indemnification.

participant, and such designees or asserted against Secured Party, any
participant, and such designees, directly or indirectly, in connection with the
existence of or the exercise of any of the rights of Secured Party under this
Security Agreement or any of the of the Related Documents except to the extent
the same arises by reason of the gross negligence or willful misconduct of the
Person seeking indemnification.

change its address for notices under this Agreement by giving formal written
notice to the other parties, specifying that the purpose of the notice is to
change the party's address. To the extent permitted by applicable law, if there
is more than one Debtor, notice to any Debtor will constitute notice to all
Debtors. For notice purposes, Debtor agrees to keep Secured Party informed at
all times of Debtor's current address(es).

               Section 10.8.  Severability.
If a court of competent jurisdiction finds any provision of this Agreement to be
invalid or unenforceable as to any person or circumstances, such finding shall
not render that provision invalid or unenforceable as to any other persons or
circumstances. If feasible, any such offending provision shall be deemed to be

Secured Party shall not be deemed to have waived any rights under this
Agreement, unless such waiver is given in writing and signed by Secured Party.
No delay or omission on the part of Secured Party in exercising any right shall
operate as a waiver of such right or any other right. A waiver by Secured Party
of a provision of this Agreement shall not prejudice or constitute a waiver of
Secured Party's right otherwise to demand strict compliance with that provision
or any other provision of this Agreement. No prior waiver by Secured Party, nor
any course of dealing between Secured Party and Debtor, shall constitute a
waiver of any of Secured Party's rights or of any obligations of Debtor as to
any future transactions. Whenever the consent of Secured Party is required under
this Agreement, the granting of such consent by Secured Party in any instance
shall not constitute continuing consent in subsequent instances where such
consent is required and in all cases such consent may be granted or withheld in
the sole discretion of Secured Party.

               Section 10.10.  Confidentiality.
In handling any confidential information Secured Party shall exercise the same
degree of care that it exercises with respect to its own proprietary information
of the same types to maintain the confidentiality of any non-public information
thereby received or received pursuant to or in connection with this Agreement
except that disclosure of such information may be made (i) to the Subsidiaries

the Loans, provided that they have entered into a comparable confidentiality
agreement in favor of Debtor and have delivered a copy to Debtor, (iii) as

order and (iv) as may be required in connection with the examination, audit or
similar investigation of Secured Party. Confidential information hereunder shall

knowledge or possession of Secured Party when disclosed to Secured Party, or
becomes part of the public domain after disclosure to Secured Party through no
fault of Secured Party; or (b) is disclosed to Secured Party by any third party,
provided Secured Party does not have actual knowledge that such third party is
prohibited from disclosing such information.

               Section 10.11.  Counterparts.
This Agreement may be executed in any number of counterparts, each of which when
so executed and delivered shall be deemed an original, but all such counterparts
together shall constitute but one and the same instrument.

DEBTOR AND SECURED PARTY EACH HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY

                           Security Agreement, Page 2
<PAGE>   3

right, title, claim or interest (by way of Lien or otherwise) in, against or to
the Collateral other than Permitted Liens; (b) Secured Party has or, in the case
of after-acquired Collateral, will have, a perfected first-priority security
interest in the Collateral subject to Permitted Liens; and (c) Debtor does not

applications in, the Patent and Trademark Office, the Copyright Office or any
similar offices or agencies in any other country or any political subdivision

               4. Covenants Relating to Collateral. Debtor hereby agrees (a) to
perform all commercially reasonable acts that may be necessary to maintain,
preserve, protect and perfect the Collateral, the Lien granted to Secured Party
therein and the first priority of such Lien, subject to Permitted Liens,
provided, however, that Debtor not be required to perfect Secured Party's
security interest in any Collateral located outside the U.S., or perfect the
registration of Intellectual Property outside of the U.S.(b) to appear in and
defend any action or proceeding which may affect its title to or Secured Party's

request from time to time; (d) on a continuing basis, but not more frequently
than once per calendar quarter to make, execute and acknowledge and deliver
appropriate filings with the Patent and Trademark Office and the Copyright
Office, including one or more Powers of Attorney substantially in the form of

unless an Event of Default has occurred and is continuing.

               5. Notice of Patent, Trademark or Copyrights. Debtor will
promptly notify Secured Party upon (a) the filing by Debtor of an application
for the registration of any Patent, Trademark or Copyright with the United
States Patent and Trademark Office or the United States Copyright Office or any
similar office or agency or any political subdivision thereof, or (b) the
acquisition by Debtor of any Patent, Trademark or Copyright that is filed with

subdivision thereof.

               6. Successors and Assigns. This Security Agreement shall bind and
inure to the benefit of the respective successors and permitted assigns of each
of the parties; provided, however, that neither this Agreement nor any rights
hereunder may be assigned by Debtor without Secured Party's prior written
consent, which consent may be granted or withheld in Secured Party's sole
discretion. Secured Party shall have the right at any time with the consent of
Debtor, not to be unreasonably withheld to sell, transfer, or negotiate all or
any part of, or any interest in the Loan Obligations, this Agreement or any of
the Related Agreements, and upon any such sale, transfer or negotiation, the
assignee thereof shall be entitled to all of the right title and interest of the
Secured Party so transferred.

               7. Severability. If a court of competent jurisdiction finds any
provision of this Security Agreement to be invalid or unenforceable as to any
person or circumstances, such finding shall not render that provision invalid or
unenforceable as to any other persons or circumstances. If feasible, any such
offending provision shall be deemed to be modified to be within the limits of
enforceability or validity; however, if the offending provision cannot be so
modified, it shall be stricken and all other provisions of this Security
Agreement in all other respects shall remain valid and enforceable.

               8. Waiver. Secured Party shall not be deemed to have waived any
rights under this Security Agreement, unless such waiver is given in writing and
signed by Secured Party. No delay or omission on the part of Secured Party in
exercising any right shall operate as a waiver of such right or any other right.
A waiver by Secured Party of a provision of this Agreement shall not prejudice
or 


- --------------------------------------------------------------------------------
                           Security Agreement, Page 3
<PAGE>   4


constitute a waiver of Secured Party's right otherwise to demand strict
compliance with that provision or any other provision of this Security
Agreement. No prior waiver by Secured Party, nor any course of dealing between
Secured Party and Debtor, shall constitute a waiver of any of Secured Party's
rights or of any obligations of Debtor as to any future transactions. Whenever
the consent of Secured Party is required under this Security Agreement, the
granting of such consent by Secured Party in any instance shall not constitute
continuing consent in subsequent instances where such consent is required and in
all cases such consent may be granted or withheld in the sole discretion of
Secured Party.

               9. Counterparts. This Security Agreement may be executed in any
number of counterparts, each of which when so executed and delivered shall be
deemed an original, but all such counterparts together shall constitute but one
and the same instrument.

                     COMMON STOCK WARRANT PURCHASE AGREEMENT


        THIS COMMON STOCK WARRANT PURCHASE AGREEMENT (the "Agreement") is made
and entered into as of the 12th day of March, 1998 by and among FIRST VIRTUAL
CORPORATION, a Delaware Company (the "Company") and Hambrecht & Quist Guaranty
Finance, LLC., a California limited liability company ("H&QGF"). H&QGF shall be
referred to herein as the "Investor." As used in this Agreement, the term
"Shares" shall mean the shares of Common Stock issuable upon exercise of the
Warrant, as defined in Section 1.1 below, or upon exercise of the right to
convert the Warrant, as provided under Section 7 of the Warrant (the "Conversion
Right").

        The parties hereto agree as follows:

        Article 1.  Sale and Purchase of Warrant; Closing.

               1.1 Sale and Purchase of Warrant. The Company agrees to sell to
the Investor and the Investor agrees to purchase from the Company for a purchase
price of $1,250.00, a warrant in the form attached hereto as Exhibit A to
purchase 125,000 shares of the Company's Common Stock (the "Common Stock") at an
initial per share exercise price of $8.00 at any time on or before March 1,
2003. The warrant to be issued to H&QGF hereunder shall be referred to herein as
the "Warrant".

               1.2 Closing. The issuance of the Warrant shall take place on the
even date hereof, or on such other date as the parties shall mutually agree (the
"Closing"). At the Closing, the Company shall cause to be delivered to the
Investor the Warrant issued in the name of such Investor and Investor shall pay
the Company $1,250.00.

        Article 2. Representations and Warranties of the Company. The Company
hereby agrees and represents and warrants to the Investor as follows:

               2.1 Corporate Status. The Company is a corporation duly
organized, validly existing, and in good standing under the laws of the State of
Delaware and has all requisite legal and corporate power and authority to own,
lease and operate its properties and assets and to carry on its business as now
conducted and as proposed to be conducted.

               2.2 Capitalization. Immediately prior to the Closing, the
authorized and outstanding capitalization of the Company will consist of that
which is described on Schedule 1. Except as provided in Schedule 1, there are no
outstanding rights, options, warrants or agreements for the purchase or
acquisition from the Company of any shares of its capital stock. The Company is
not a party or subject to any agreement, and, to the best of its knowledge,
there is no agreement or understanding between any other persons, which relates
to the voting or giving of written consents with respect to any security or by a
director of the Company.

               2.3 Authorization. All corporate action on the part of the
Company, its officers, directors and shareholders necessary for the
authorization, execution, delivery and performance of this Agreement and the
consummation of the transactions contemplated hereby or thereby, including the
authorization, issuance and delivery of the Warrant, the reservation of the
Shares issuable upon the exercise thereof, and the grant of registration rights
to the Investor, has been taken or will be taken prior to Closing. The person
signing this Agreement has full power and authority to enter into this Agreement
on behalf of the Company. When executed and delivered, this Agreement will
constitute a valid and binding obligation of the Company except as
enforceability may be limited by the general laws of general application
relating to bankruptcy, insolvency and the





                                     Page 1

relief of debtors and the rules of law or principles at equity governing
specific performance, injunctive relief and other equitable remedies.

               2.4 Corporate Power. The Company has all requisite legal and
corporate power and authority to enter into this Agreement and all requisite
legal and corporate power and authority to issue and deliver the Warrant and the
Shares and to carry out and perform its obligations under the terms and
conditions of this Agreement.

               2.5 Validity of Warrant. The Warrant to be issued and delivered
pursuant to this Agreement shall constitute valid and binding obligations of the
Company. The Shares have been duly and validly reserved, and when issued in
accordance with the Warrant shall be duly authorized, validly issued, fully paid
and free of any liens or encumbrances except for restrictions on transfer
provided for under applicable federal and state securities laws. During the
period within which the purchase rights represented by the Warrant may be
exercised, the Company shall at all times have authorized, and reserved for
issuance upon exercise of the Warrant or upon exercise of the Conversion Right,
a sufficient number of shares of Common Stock to provide for the issuance of the
Shares. The issuance of such Common Stock is not and will not be subject to any
preemptive rights or rights of first refusal except such as have been
effectively waived.

               2.6 Compliance with Other Instruments. The Company is not in
violation of, conflict with or default under (i) any provision of its amended
and restated certificate of incorporation or bylaws, or (ii) any contract,
instrument, judgment, order, writ or decree to which it or any of its
subsidiaries is a party or by which it or any of them is bound, or, to the best
of its knowledge, of any provision of any federal or state statute, rule or
regulation applicable to the Company or any of its subsidiaries except as would
not have a material adverse effect on the assets, condition, affairs or
prospects of the Company and its subsidiaries taken as a whole, financial or
otherwise (a "MAE"). The Execution, delivery and performance of this Agreement,
and the consummation of the transactions contemplated hereby and thereby,
including the authorization, issuance and delivery of the Warrant, the
reservation of the Shares issuable upon exercise thereof and the grant of
registration rights to the Investor, will not, with or without the passage of
time and giving of notice, result in any such violation, conflict or default, or
an event that results in the creation of any material lien, charge or
encumbrance upon any assets of the Company or any of its subsidiaries or the
suspension, revocation, impairment or forfeiture of any material permit,
license, authorization, or approval applicable to the Company or any of its
subsidiaries which is reasonably likely to have a MAE.

        Article 3. Representations and Warranties of the Investor. The Investor
represents and warrants to the Company that:

               3.1 Authorization. The person signing this Agreement has full
power and authority to enter into this Agreement on behalf of the Investor. When
executed and delivered, this Agreement will constitute the Investor's valid and
legally binding obligation.

               3.2  Investment Representations.

               (a) The Investor understands that the Warrant and the Shares have
        not been registered under the Securities Act of 1933, as amended (the

        contained in the Act based in part upon the representations of the
        Investor contained herein and that the Company's reliance on such
        exemption as predicated on the representations set forth in this Section
        3.2.

<PAGE>   3

               (b) The Investor is acquiring the Warrant and the Shares for
        investment purposes only, solely for its own account and not as a

        distribution thereof.

               (c) The Investor is a sophisticated investor experienced in
        venture capital investing and able to fend for itself. The Investor is
        able to bear the economic risk of the purchase of the Warrant and the
        Shares, including a complete loss of the Investor's investment. The
        Investor has been afforded an opportunity to ask such questions of the
        Company's officers, employees, agents, accountants and representatives
        concerning the Company's business, operations, financial condition,
        assets, liabilities and other relevant matters as it has deemed
        necessary or desirable.

               (d) Investor understands that if the Company does not register
        the Shares with the Securities and Exchange Commission pursuant to
        Section 12 of the 1933 Act, or file reports pursuant to Section 15(d) of
        the Securities Exchange Act of 1934 ( the "1934 Act"), or if a
        registration statement covering the securities under the 1933 Act is not
        in effect when it desires to sell (i) the rights to purchase Common
        Stock pursuant to the Warrant, or (ii) the Common Stock issuable upon
        exercise of the right to purchase, it may be required to hold such
        securities for an indefinite period. Investor also understands that any
        sale of the rights of the Investor to purchase Common Stock which might
        be made by it in reliance upon Rule 144 under the 1933 Act may be made
        only in accordance with the terms and conditions of that Rule.

               (e) Investor is an "accredited investor" within the meaning of
        Rule 501 of Regulation D under the Act, as presently in effect.

               (f) Investor is a resident of the State of California.

warranties of the Company contained in Article 2 hereof shall be true and

               4.3 Opinion of Counsel. There shall have been delivered to the
Investor an opinion of the Company's counsel dated as of the date of the Closing
in substantially the form attached hereto as Exhibit B.

               4.4 Delivery of Warrant. There shall have been delivered to the
Investor the Warrant.

               4.5 Governmental Consents. All permits, consents, approvals,
orders and authorizations, if any, which the Company is required to obtain from,
and all registrations, qualifications, designations, declarations and filings
which the Company is required to make with, any federal or state governmental
authority of the United States in connection with the execution, delivery or
performance of this Agreement, the consummation of the transactions contemplated
hereby or the issuance and delivery of the Warrant to the Investor pursuant to
this Agreement, except post-sale filings which may be required under the Blue

such laws), shall have been duly obtained or made and shall be effective on and

Agreement, the Company will obtain the requisite consent of stockholders of the
Company to amend the Amended and Restated Investors' Rights Agreement between
the Company and the investors named therein, dated as of August 29, 1996 (the

Rights Agreement and to include the Shares as Registrable Securities as defined

performance of this Agreement, the consummation of the transactions contemplated
hereby or the issuance and delivery of the Warrant to the Investor pursuant to
this Agreement, except post-sale filings which may be required under the Blue
Sky laws of any applicable states (which the Company hereby agrees to make in
accordance with such laws), shall have been duly obtained or made and shall be
effective on and as of the Closing.

        Article 6. Financial Statements. So long as the Investor continues to

year, a consolidated balance sheet of the Company as of the end close of the
fiscal year, and a consolidated statement of cash flows for such fiscal year,

this Warrant may be repurchased by the Company (the "Repurchase Right") at any
time after December 31, 1998 and before January 15, 1999, if less than
$5,000,000 of principal is outstanding on one or more days beginning on the date
of the Loan Agreement and until December 31, 1998, as further described herein.

               (a) The number of shares subject to the Repurchase Right (the

To the extent that the Repurchase Right is not exercised by the Company on or
prior to January 15, 1999, then the Repurchase Right shall be deemed
automatically exercised pursuant to this Section 2 immediately prior to the
expiration of the Repurchase Right. To the extent that the Repurchase Right is
exercised in accordance with this Section 2, the Company will pay Holder a fee
of one cent ($0.01) for each Repurchaseable Share repurchased and issue a
replacement Warrant to the Holder for the remaining number of Shares subject to
