PART I

ITEM 1. BUSINESS

OVERVIEW

NetSpeak develops, markets, licenses and supports a suite of intelligent
software modules which provide business solutions for concurrent, real-time
interactive voice, video and data communications over packetized data networks
such as the Internet, local-area networks (LANs) and wide-area networks (WANs).
NetSpeak's products allow organizations to build new voice and video-enabled
communications networks or to add these communications capabilities to their
existing enterprise. The Company's solutions integrate a variety of features and
functions commonly found in traditional voice transmission networks into
packetized data networks. NetSpeak is focused on developing a suite of
interoperable products that provide scalability, reliability, redundancy,
systems management, remote operations, administration and maintenance features.
The Company's product lines consist of call management software, gateway systems
and software based client telephones. The primary target end-users for the
Company's products and solutions are service providers, including traditional
and next generation telecommunications carriers, business enterprises, cable
companies and original equipment manufacturers ("OEMs").

Since inception, the Company's product development efforts have focused
on integrating its technology into the product lines of its strategic partners.
During this period, the Company has established a number of strategic alliances
with leaders in the communications industry in an effort to facilitate and

3
<PAGE>

accelerate the acceptance and distribution of NetSpeak's technology and
products, by leveraging its partners' existing sales and distribution channels.
To date, the Company's most significant strategic relationships have been with
larger OEMs, like Motorola, Inc. ("Motorola").

The Company is now focusing its development and marketing efforts to
create prepackaged solutions that can be configured and combined with other
vendors' equipment to provide a variety of voice over IP solutions with minimal
customization. In contrast to integrating the Company's technology into the
product lines of OEMs, the Company believes prepackaged solutions will enable it
to expand the distribution of its products by allowing it to broaden its
indirect sales channel by making its products easier to sell. In marketing these
products, the Company intends to target value-added resellers ("VARs") and
system integrators ("SIs") that concentrate on the computer telephony and
networking industries. In connection with this effort, the Company has
substantially expanded its management team with the addition of five new
members. These individuals share extensive experience in commercializing
technology into marketable products and expanding channels of distribution and
have assumed significant roles in managing and coordinating this effort.

NetSpeak is also committed to performing substantial ongoing research and
development activities in order to develop new IP telephony applications and
extend the features and functionality of its current product line. As a result,
the Company will likely increase its investments in research and development.

INDUSTRY BACKGROUND

There are two fundamentally different switching technologies that exist
today which enable voice communications: circuit switching and packet switching.
Since the invention of the telephone, the traditional public switching telephone
network ("PSTN") has been based on circuit switching technology. To date, packet
switching technology has primarily been utilized in data networks. The
historical evolution of these switching technologies has focused on meeting and
enhancing the performance requirements of applications for which each technology
was initially intended, as a result two disparate network infrastructures have
emerged. The existence of disparate networks, as well as numerous compelling
reasons, has lead to the development of transmitting voice over IP data
networks.

In 1995, IP telephony applications were initially introduced to the
market. At that time, the market consisted of client software programs that
allowed an end user to conduct a voice call over the Internet from a
multimedia equipped PC with another end user connected to the Internet who was
deploying the same software. By the end of 1995, a number of companies,
including NetSpeak, were offering software based client IP telephones. The
concept was simple, but Internet telephones had numerous limitations, such as
poor voice quality and call participants had either to prearrange their calls or
make them when both parties happened to be connected to the Internet and logged
into a directory server.

Since 1996, IP telephony has evolved to become the focus of many
technology vendors and service providers. The capability and quality has
advanced considerably with users primarily seeking benefits to reduce the cost
of voice and fax calls through toll bypass and to enable new applications
through the combination of telephony, computer and data functions, using IP
networks as the common communications platform. Up until now, cost reduction has
been the primary driving force behind IP telephony deployments and trials. In
the service provider domain, toll bypass is accomplished by allowing the caller
to originate a call using a standard telephone on the local PSTN network to a
gateway which transfers the call to the Internet or the service provider's IP
network. The call is transmitted over the IP network to another gateway close to
the destination, where it is transferred to the local PSTN and the called
party's standard telephone. Enterprise solutions seek to save toll charges by
routing inter-office long-distance calls over a data network, such as LANs and
WANs, that already links the enterprise offices for data communications.

<PAGE>

Significant advances in both standards and technology have accompanied
this evolution. Initially, to overcome the poor quality issues, proprietary
solutions emerged as standards were still evolving. Many of the functions
previously performed in client software, like voice encoding, compression and
packetization were incorporated into IP telephony gateways, which increased
performance and voice quality. Although these advancements brought necessary
improvement in IP telephony applications, proprietary implementations hindered
adoption rates as service providers and enterprises were locked into a
particular vendor's solution. Recognition of the need for interoperability has
produced advances in the development of standards and widespread support for a
suite of protocols called ITU H.323 ("H.323") to address the signaling,
communications, network management and security aspects of IP telephony. These
open, standards-based approaches and vendor commitments to interoperability
gained strong momentum during 1998.

While toll bypass remains a significant motivation for the deployment of
IP telephony, the opportunity for this application in the PSTN domain will
likely begin to disappear over the next few years as toll prices are reduced to
compete with IP telephony prices and regulatory induced cost burdens are reduced
to reflect true economic costs. The future of IP telephony is tied to the
convergence of voice and data networking infrastructures and the ubiquity of IP
as the end-to-end communications protocol that will run on these converged
networks.

The growing maturity of data network technologies and their widespread
adoption by both enterprises and service providers has led to a correspondingly
wide recognition that today's disparate network infrastructures for voice, data
and video will be united on a common packet network infrastructure. According to
industry analysts, packet switching equipment doubles in performance
approximately every 20 months, while circuit switches take about 80 months, four
times as long, to achieve the same relative improvement. Several "next
generation" telephone companies, like Qwest Communications International, Inc.
and Level 3 Communications, Inc., are building their networks entirely on packet
infrastructures and IP networking. The cable and wireless data industries have
also decided to adopt packet and IP telephony platforms for converged voice,
data and video infrastructure and are currently developing specifications and
architectures for those platforms.

A combined voice and data infrastructure brings numerous benefits of which
the most compelling is economics. Voice communications are significantly less
expensive to transmit utilizing IP technology as compared to traditional circuit
switched networks. Additionally, incremental costs of new services and
applications are lowered because the common infrastructure is shared, network
management is simplified around a common set of tools and processes, and the use
of open standards can allow innovators to develop more enhanced applications
combining voice, data and video functionality. IP is the universal end-to-end
communications protocol that is used over the many underlying packet
technologies - from ATM in the PSTN, through frame relay in the enterprise WAN
to Ethernet on the LAN. Enhanced services and applications of IP telephony,
reflecting integration of voice and data functionality, are becoming
increasingly common. These support multimedia communications, collaboration or
commerce. One example is call-enabled web pages, which allows a visitor to a web
site to select a button on the web page which automatically establishes a call
into pre-programmed corporate locations, such as the sales department or
customer service.

The Company believes that IP telephony will ultimately gain widespread
acceptance, although several things need to occur for IP telephony to reach its
full potential. First, voice service quality needs to be equivalent or very
close to that of the PSTN. Although IP-based communications quality is enhanced
daily, a large majority of users have yet begun to recognize the advancements
being made. Second, the changes in equipment infrastructure used by major
telecommunications providers usually require a

5
<PAGE>

lengthy trial period. The Company believes that the speed at which IP telephony
is being adopted is increasing rapidly and will pick up significant momentum
through 1999.

NETSPEAK'S STRATEGY

The Company's goal is to develop and broadly distribute a suite of
interoperable call management, gateway and client software products and
solutions that provide concurrent real-time interactive voice, video and data
transmissions over IP networks. The Company seeks to seamlessly integrate
features and functions commonly found in traditional voice transmission networks
into the packetized data-networking environment. The primary target end-users
for the Company's products and solutions are service providers, including
traditional and next generation telecommunications carriers, business
enterprises, cable companies and OEMs. The Company's strategy includes the
following key elements:

TRANSITION FROM A TECHNOLOGY TO PRODUCT FOCUS

Since inception, the Company's product development efforts have focused on
integrating its technology and products into the product lines of its strategic
partners. The Company is now focusing its development activities to create
prepackaged solutions that can be configured and combined with other vendors'
equipment to provide a variety of voice over IP solutions with minimal
customization.

EXPANSION OF STRATEGIC ALLIANCES AND INDIRECT SALES CHANNELS

Since inception, the Company has established a number of strategic
alliances with leaders in the communications industry in an effort to facilitate
and accelerate the acceptance and distribution of NetSpeak's technology and
products, by leveraging its partners' existing sales and distribution channels.
To date, the Company's most significant strategic relationships have been with
larger OEMs, like Motorola. In contrast to integrating the Company's technology
into the product lines of OEMs, the Company believes that prepackaged solutions
will enable it to significantly expand the distribution of its products by
allowing it to broaden its indirect sales channels by making its products easier
to sell. In marketing these products, the Company intends to target VARs and SIs
that concentrate on the computer telephony and networking industries. NetSpeak
anticipates that it will also increase its internal sales force to concentrate
on recruiting and developing these new distribution partners. In connection with
this effort, the Company has substantially expanded its management team by the
addition of five new members. These individuals share extensive experience in
commercializing technology into marketable products and expanding channels of
distribution and have assumed significant roles in managing and coordinating
this effort. The Company believes that it will perform limited direct sales
activities and such efforts will be targeted only towards larger organizations
that prefer to work directly with its vendors.

CONTINUE RESEARCH AND DEVELOPMENT

NetSpeak is committed to performing substantial ongoing research and
development activities in order to develop new IP telephony applications and
extend the features and functionality of its current product line. As a result,
the Company will likely increase its investments in research and development.

TECHNOLOGY, SOLUTIONS AND PRODUCTS

TECHNOLOGY

NetSpeak has developed a core communications technology, which addresses
the challenges associated with real-time interactive voice transmission over
packetized data networks and integrates features commonly found in traditional
voice transmission networks into its products. The Company's

6
<PAGE>

core communications technology is the platform utilized throughout its products
and solutions. NetSpeak's technology is based on industry standards and provides
vendor interoperability, scalability, reliability, redundancy, data encryption,
network and system management, remote operation, administration and maintenance
features, among other things. The Company uses a common object-oriented code
base that enables its technology to be ported to various operating platforms.

In order to establish a competitive advantage, NetSpeak continues to
perform substantial research and development activities to enhance its core
technology, primarily through development of new IP telephony applications and
extension of the features and functionality of its current product line.

SOLUTIONS

NetSpeak's products can be configured and combined with other vendors'
equipment to provide a variety of solutions for IP telephony end-users. Some of
the most common applications that NetSpeak targets are toll-bypass, WebPhone
e-Commerce and WebPhone 2nd Line.

TOLL-BYPASS

Toll-bypass or toll reduction involves deploying IP telephony gateways at
multiple locations and linking them together through the Internet or a private
managed IP network. Users of the network access the gateways by calling them
directly from the traditional PSTN or through an IP client telephone. Calls are
then transmitted across the IP network to the destination gateway and are then
sent back to the PSTN, thereby bypassing the PSTN for the majority of the call
transmission resulting in the elimination or reduction of traditional long
distance and/or local calling charges. For corporate users with existing IP
networks connecting remote sites, gateways can be used to provide high
quality voice communications at a lower cost than traditional long distance
circuits. Additionally, NetSpeak's products support the use of toll-bypass
applications through prepaid calling card services.

WEBPHONE E-COMMERCE

WebPhone e-commerce involves embedding a link on an organization's World
Wide Web site that establishes an audio channel between a NetSpeak client IP
telephone on the user's desktop and a gateway located in the entity's call
center. This enables individuals browsing organizations' web site to quickly and
easily speak with a customer service agent over a single communication line
without disconnecting from the Internet. This application will provide a company
with the opportunity to extend its sales, support and service reach to its
customers.

WEBPHONE 2ND LINE

WebPhone 2nd Line enables individuals to make and receive telephone
calls over a single circuit while connected to the Internet. This application
offers telecommunications carriers the ability to increase call completion
rates and the associated revenue without customers having to install a second
telephone line in their home.

PRODUCTS

GENERAL

NetSpeak's product lines consist of call management software, gateway
systems and software based client telephones. The Company has focused on
developing its suite of products and solutions to

7
<PAGE>

include vendor interoperability through compliance with industry standards,
scalability, reliability, and redundancy, as well as a number of other features,
including systems management, remote operations, administration and maintenance.

CALL MANAGEMENT SOFTWARE

NetSpeak's call management software solutions provide centralized
intelligent system and network management for IP telephony networks. These
modules monitor and control the interaction between network end points, such as
gateways and client telephones, as well as the interaction between separate IP
telephony networks. Call management software provides features to IP telephony
networks similar to those commonly found in the PSTN such as priority call
routing, network management operations, user activity records, account billing
information, user authentication and verification, among others. The centerpiece
of NetSpeak's call management solution is the Connection Server, which provides
functionality similar to advanced IP telephony gatekeepers. Other critical
components of NetSpeak's call management solution are the Routing Server which
dynamically manages call routing between multiple gateways and clients, the
Event Management Server, which provides call detail records utilized for
real-time billing and monitoring system performance and the Control Center
module, which manages all of NetSpeak's call management applications. NetSpeak's
call management solutions are being adapted to H.323 standards.

GATEWAY SYSTEMS

Gateway products represent transition points between two different network
types, such as between the PSTN and IP networks. Gateways perform encoding,
compression and delivery of traditional voice transmissions to or from
packetized data networks. Enterprises using NetSpeak's gateway products can
deploy real-time packet-based voice communications over existing data networks.

The NetSpeak Gateway Exchange is an H.323 compliant voice over IP Gateway
server. This product is an integrated gateway system, where the Company combines
third-party computer hardware and software components with its internally
developed gateway software to form a "turn-key" system. The NetSpeak Gateway
Exchange is PC-based and offers up to 96 ports in a single chassis with digital
T1, E1 and standard analog PSTN network interfaces. The gateway supports E&M,
MFCR2, ISDN (Euro and National) and Feature Group D PSTN signaling protocols.
The data network interface is 10-BaseT. The NetSpeak Gateway Exchange also
incorporates such features as programmable call flow scripting, silence
suppression, low latency, network-based load partitioning, alarms and real-time
operational measurements, among others. The Company's gateway software operates
on Natural Microsystems' Fusion platform and Microsoft's Windows NT operating
system.

CLIENT SOFTWARE

NetSpeak's WebPhone is a fully functional client or end-user PC software
based IP telephone. WebPhone provides users with the ability to engage in
real-time voice, video and data communications over the Internet and other IP
based networks. WebPhone is H.323 compliant and offers many features commonly
found in tradition telephones such as full-duplex voice communications,
integrated voice mail and caller identification information, among others. The
WebPhone product line includes NetSpeak's Standard and Mini WebPhones. The
standard edition WebPhone is a component of NetSpeak's toll bypass and WebPhone
2nd line solutions and is also used directly by end-users to communicate over
the Internet. The Mini WebPhone, which is smaller in size and can be quickly
downloaded and configured, is a key component of NetSpeak's WebPhone e-commerce
solution.

STRATEGIC ALLIANCES

MOTOROLA

In August 1996, the Company established a strategic alliance with
Motorola, as part of which Motorola made a minority investment in the Company.
In March 1998, NetSpeak and Motorola expanded their existing strategic alliance
and entered into a joint development and technology license agreement in which
NetSpeak granted Motorola an exclusive license to develop RF (Radio Frequency)
products using the Company's technology. Under the agreement, the companies seek
to join their technologies to enable IP multimedia communications on wireless
networks. As such, Motorola is entitled to include NetSpeak's technology in its
wireless infrastructure products (such as cellular phones, pagers, satellite
phones, and two-way radios) to support real-time multimedia communications (e.g.
voice, fax, audio, video, data) over a variety of wireless networks. To date,
Motorola has not embedded the Company's technology into its products. Under the
Agreement, the Company received a $30 million multi-year minimum purchase
commitment from Motorola. As of December 31, 1998, $27.5 million remained under
the commitment, which is subject to certain conditions. The acceptance of a
specific technology platform being developed by NetSpeak (the "Platform") was
defined in the contract as the trigger for the minimum purchase commitment.
Subsequently, a decision was made to terminate any further development efforts
for the Platform in favor of aggressively pursuing the development of our new
software call processing technology. NetSpeak and Motorola are in discussions
regarding replacing the acceptance of the Platform with another triggering
event. Although the Company believes that it will be successful in negotiating a
new trigger for the minimum commitment, there can be no assurances that NetSpeak
will be successful in this effort and as a result there exists some uncertainty
as to the receipt, amount and timing of the remaining minimum commitment from
Motorola.

In conjunction with the agreement, on April 22, 1998 Motorola consummated
a tender offer, acquiring 2,686,470 shares of NetSpeak's Common Stock at $30.00
per share. Upon the consummation of the tender offer, Motorola purchased an
additional 35,000 shares of common stock from two officers at the tender offer
price. As of December 31, 1998, Motorola owned 30.9% of the Company's total
outstanding common stock. Three designees of Motorola serve on the Company's
Board of Directors.

OTHER ALLIANCES

In January 1998, the Company entered into a joint development and stock
purchase agreement with Bay Networks, Inc. ("Bay Networks"). In connection with
the agreements (a) the Company issued approximately 1.3 million shares of
NetSpeak's Common Stock to Bay Networks for $36.8 million, net of offering costs
and (b) Bay Networks and NetSpeak agreed to jointly develop and market IP
telephony products. Subsequent to the consummation of such agreement, Bay
Networks was acquired by Northern Telecom Limited ("Nortel") and, as a result of
the change in ownership, all joint development projects between the companies
were suspended. Nortel has advised the Company that it will pursue its own IP
telephony strategy, which at this time does not include NetSpeak's technology.

In 1997, the Company established a strategic partnership with Siemens
Telecom Networks ("Siemens"). In connection with the related OEM agreement,
Siemens incorporates a portion of NetSpeak's source code on its gateway platform
and markets certain of the Company's products. The Company's exclusivity with
Siemens expired in December 1998, however Siemens continues to market the
Company's products.

In connection with the development of its technology, the Company has also
established strategic relationships with Creative Technology Ltd. ("Creative")
and MCI Worldcom. As NetSpeak is transitioning its focus to prepackaged
solutions, the Company is uncertain as to the future opportunities with these
companies at this time.

SALES AND MARKETING

The primary target end-users for the Company's products and solutions are
service providers, including traditional and next generation telecommunications
carriers, business enterprises, cable companies and OEMs. The Company's primary
focus is to offer its products and solutions to the market through indirect
sales channels, such as VARs, SIs and OEMs. The Company also markets its
WebPhone client software products to consumers over the Internet and through
distribution agreements with over 1,000 ISPs worldwide. The Company believes
that it will perform limited direct sales activities and such efforts will be
targeted only towards larger organizations that prefer to work directly with its
vendors.

Since inception, the Company's sales and marketing efforts have focused on
establishing and building strategic relationships with leaders in the
communications industry in an effort to enhance the distribution of the
Company's products by leveraging its partners' existing sales channels. To date,
the Company has obtained larger OEMs as its strategic partners. The Company is
now focusing its marketing efforts to create prepackaged solutions that can be
configured and combined with other vendors' equipment to provide a variety of
voice over IP solutions. In contrast to integrating the Company's technology
into the product lines of OEMs, prepackaged solutions will enable the Company to
expand the distribution of its products by allowing it to broaden its indirect
sales channel making its products easier to sell. In marketing these products,
the Company will target VARs and SIs that focus on the computer telephony and
networking industries. NetSpeak anticipates that it will also increase its
internal sales force to concentrate its efforts on recruiting new partners,
educating partners on the Company's products and assisting partners in customer
presentations. The Company will also seek to establish marketing and support
programs to assist channel partners' efforts in the sale of its products. In
connection with this effort, the Company has substantially expanded its
management team by the addition of five new members. These individuals share
extensive experience in commercializing technology into marketable products and
expanding channels of distribution and have assumed significant roles in
managing and coordinating this effort.

The Company's external marketing activities consist of attending industry
trade shows, advertising, and other marketing campaigns which are primarily
intended to educate potential customers as to the features, functionality, cost
effectiveness and other benefits of NetSpeak's products and solutions. In
addition, the Company's web site at http://www.netspeak.com (which is not deemed
to be part of this Report) permits prospective customers to obtain information
about its products and solutions, download software for evaluation and order
certain products. The Company intends to continue to intensify and expand its
sales and marketing efforts and, as a result, anticipates that sales and
marketing expenses will increase in future periods.

CUSTOMER SERVICE AND SUPPORT

NetSpeak is committed to maintaining customer satisfaction and loyalty.
The Company provides technical support services to its direct customers, VARs,
SIs and strategic partners. The Company maintains a technical support hotline in
which the Company's customer support specialists diagnose and resolve technical
problems related to the Company's products as well as other hardware and
software in which the Company's products may interact. The Company also
maintains an on-line database of technical problems and the related solutions on
its web site at http://www.netspeak.com. Customer support activities are tracked
through customer databases. The Company uses customer feedback as a source of
ideas for product improvements and enhancements.

Additionally, the Company provides maintenance for its products through
periodic technical upgrades. The Company's products include 90 days of
maintenance and support service. The Company

10
<PAGE>

provides various levels of maintenance and support services to its customers for
a fee.

RESEARCH AND DEVELOPMENT

The IP telephony industry is characterized by rapidly changing technology,
evolving industry standards and frequent new product introductions. The Company
is involved in the review and establishment of industry standards by actively
participating in standard setting bodies. Management believes that the Company's
future success is highly dependent upon its ability to quickly adapt to changes
in the marketplace and to continue enhancing the functionality of its products.

The Company currently conducts the majority of its product development
efforts in-house. On occasion, the Company employs independent contractors and
its strategic partners to assist with product development and testing
activities. The Company has aggressively expanded its research and development
group from six software engineers as of December 31, 1995 to 63 software
engineers and support staff as of December 31, 1998. Research and development
expenses were approximately $9.6 million for the year ended December 31, 1998
and approximately $5.5 million and $2.3 million in 1997 and 1996, respectively.
All of the Company's research and development costs have been expensed as
incurred. The Company anticipates that research and development expenses will
increase in future periods to perform new product development and products
enhancements in an effort to establish a competitive advantage.

COMPETITION

The IP telephony industry is in the early stages of development and is
rapidly changing as voice and data networks are beginning to converge.
Competition for gateways, call management applications and client software is
becoming intensely competitive. Currently, the Company faces competition from
different companies across each of its product lines. NetSpeak competes with
companies such as Ascend Communications, Inc., Bellcore, Cisco Systems, Inc.,
Clarent Corporation, Lucent Technologies, Inc., Nortel, VocalTec Communications
Ltd. and 3Com Corporation. The Company anticipates that competition will
continue to escalate in all market segments as companies in the
telecommunications and computer industries will introduce competitive products
into the market. Although the Company faces increased competition in the market,
these companies may represent existing and potential future customers and
strategic partners to NetSpeak.

Many of the Company's current and potential future competitors are more
established industry participants, which posses longer operating histories,
greater name recognition, larger customer bases, longstanding customer
relationships, and significantly greater financial, technical and marketing
resources than the Company. Such companies have certain inherent cost and
competitive advantages over NetSpeak. The Company believes that the principal
competitive factors affecting its potential success include the Company's
ability to adapt to changing market conditions, new product development,
time-to-market, quality, performance, product features such as flexibility,
scalability, interoperability, functionality and ease of use, price, customer
service and support, reputation and the overall effectiveness of its sales and
marketing activities.

GOVERNMENT REGULATION

At present, there are few laws or regulations that specifically address
access to or commerce on the Internet. The increasing popularity and use of the
Internet, however, enhances the risk that the governments of the United States
and other countries in which the Company sells or expects to sell its products
will seek to regulate computer telephony and the Internet with respect to, among
other things, user privacy, pricing, and the characteristics and quality of
products and services. The Company is unable

11
<PAGE>

to predict the impact, if any, that future legislation, legal decisions or
regulations may have on its business, financial condition or results of
operations.

In March 1996, the ACTA, a group of telecommunications common carriers,
filed the ACTA Petition with the FCC arguing that providers (such as the
Company) of computer software products that enable voice transmission over the
Internet (Internet "telephone" services) are operating as common carriers
without complying with various regulatory requirements and without paying
certain charges required by law. The ACTA Petition argues that the FCC has the
authority to regulate both the Internet and the providers of Internet
"telephone" services and requests that the FCC declare its authority over
interstate and international telecommunications services using the Internet,
initiate rule-making proceedings to consider rules governing the use of the
Internet for the provision of telecommunications services, and order providers
of Internet "telephone" software to immediately cease the sale of such software.
Any action by the FCC to grant the relief sought by ACTA or otherwise to
regulate use of the Internet as a medium of communication, including any action
to permit local exchange carriers to impose additional charges for connections
used for Internet access, could have a material adverse effect on the Company's
business, financial condition and results of operations.

PATENTS AND PROPRIETARY RIGHTS

The Company generally relies upon patent, copyright, trademark and trade
secret laws to protect and maintain its proprietary rights for its products and
technology. The Company has filed 19 U.S. utility patent applications and seven
foreign patent applications relating to various aspects of the Company's
products. Several additional patent applications are currently being prepared.
The Company expects to routinely file patent applications, as deemed appropriate
to protect its technology and products.

Generally, litigation, which could be costly and time consuming, may be
necessary to determine the scope and validity of others' proprietary rights, or
to enforce any patents issued to the Company, in either case, in judicial or
administrative proceedings. An adverse outcome could subject the Company to
significant liabilities to third-parties, require the Company to obtain licenses
from third-parties, or require the Company to cease product sales and possibly
alter the design of the products. There can be no assurance that any licenses
required under any third-party patents or proprietary rights would be made
available on acceptable terms, if at all. In addition, the laws of certain
countries may not protect the Company's intellectual property.

To help protect its rights, the Company currently requires employees,
consultants and strategic partners to enter into confidentiality agreements that
prohibit disclosure of the Company's proprietary information. The Company also
currently requires employees and consultants to assign to it their ideas,
developments, discoveries and inventions. NetSpeak has entered into agreements
with customers that require the Company to place its source code in escrow.
These agreements provide that customers will have a limited, non-exclusive right
to use such code in the event that there is a bankruptcy proceeding by or
against the Company, if the Company ceases to do business or if the Company
fails to meet its support obligations. The Company may enter into similar
agreements in the future which may increase the likelihood of misappropriation
by third parties.

EMPLOYEES

As of February 28, 1999, the Company employed 124 persons, 63 in research
and development, 44 in sales, marketing and support and 17 in administration and
finance. The Company anticipates increasing its staff in future periods. None of
the Company's employees are subject to collective bargaining agreements. The
Company considers its relations with its employees to be satisfactory.

12
<PAGE>

Competition for technical personnel in the Company's industry is intense.
The Company believes that it has been successful in recruiting qualified
employees, but there is no assurance that it will continue to be as successful
in the future. There are a relatively small number of individuals who possess
the specialized technical skills that the Company requires, in close proximity
to the Company's current research and development facilities. The Company
believes that its future success depends in part on its continued ability to
hire, assimilate and retain qualified personnel.

ITEM 2. PROPERTIES

The Company occupies approximately 25,000 square feet of space in Boca
Raton, Florida, which it leases at a combined annual rental of $346,000. The
leases for the Company's facilities expire February 2001. The Company believes
that its existing facilities are adequate for its needs through the end of 1999.
Should the Company require additional space at that time or prior thereto, it
believes that such space can be secured on commercially reasonable terms and
without undue operational disruption.

ITEM 3. LEGAL PROCEEDINGS

The Company may, from time to time, be involved in certain legal actions
arising in the ordinary course of business. In the opinion of management, the
outcome of such actions known to date will not have a material adverse effect on
the Company's financial position or results of operations.

During 1998, certain shareholder litigation was filed against the Company
and its senior officers and directors in the Circuit Court of the Fifteenth
Judicial Circuit of Florida, in and for Palm Beach County. The purported class
action alleges that the Company made false and misleading statements to
shareholders in connection with Motorola's partial tender offer and that certain
of the Company's senior officers and directors improperly tendered their shares.
To date, the Company has filed a Motion to Dismiss, which has not yet been
scheduled for hearing. No discovery has taken place, nor is any anticipated
prior to the disposition of the Motion to Dismiss. The Company believes that
these complaints are without merit and intends to contest the actions
vigorously. Although the outcome of these actions cannot presently be
determined, an adverse resolution of these matters could have a material adverse
effect on the Company's financial position and results of operations.

believes, in excess of 2,500 beneficial holders of the Company's Common Stock.

The Company has never declared or paid any cash dividends on its Common
Stock and does not intend to pay dividends for the foreseeable future. The
Company intends to retain earnings, if any, to finance the development and
expansion of its business. Payment of dividends in the future will depend upon,
among other things, the Company's ability to generate earnings, need for capital
and overall financial condition.

(d) Use of IPO Proceeds

On May 29, 1997, the U.S. Securities and Exchange Commission declared
effective the Company's

15
<PAGE>

Registration Statement of Form S-1 (SEC File Number 333-22123). The offering of
the securities (the "IPO") registered pursuant to the Registration Statement
also commenced on May 29, 1997. The IPO terminated after the sale of 2,400,000
shares of the Company's Common Stock for $8.75 per share. The managing
underwriters for the public offering of the Company's Common Stock were
Josephthal, Lyon & Ross Incorporated and Cruttenden Roth, Inc.

The Company incurred expenses of approximately $1.6 million in connection
with the IPO. These expenses represented direct payments to others and not
direct or indirect payments to directors or officers of the Company or to
persons owning more than 10% of any class of securities of the Company. Net
proceeds from the IPO were approximately $17.9 million, all of which has been
used by the Company. Approximately $4.1 million was used for the purchase of
equipment, approximately $4.0 million to increase the Company's research and
development and sales, marketing and administrative staff, and the remainder was
used for working capital. None of the payments from the use of proceeds were
made to officers, directors or persons owning more than 10% of any class of
securities of the Company.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

INTRODUCTION

The Company generates revenues from product licenses and fees for
services. The principal end-users for the Company's products and solutions are
service providers, including traditional and next generation telecommunications
carriers, cable companies, business enterprises, OEMs and client software
end-users. Product license revenues are generally recognized upon product
shipment, over the license term or upon delivery of permanent authorization
codes provided that no significant post-delivery obligations and payment is due
within one year. Service revenues include fees for customer maintenance and
support and engineering. Service revenues for customer maintenance and support
are recognized ratably over the term of the maintenance period, which is
typically twelve months. Service revenues for engineering services are generally
recognized when the services are performed. If customer acceptance is a
condition, product license and service revenues are recognized upon such
acceptance. Advance payments of product licenses and services are reported as
unearned revenue until all conditions for revenue recognition are met. All
research and development costs to date have been expensed as incurred.

RESULTS OF OPERATIONS

YEARS ENDED DECEMBER 31, 1998, 1997 AND 1996

Net revenues were $7.7 million, $5.4 million and $867,000 for the years
ended December 31, 1998, 1997 and 1996, respectively.

Sales of gateway systems represented 41%, 35% and 3% of net revenues for
the years ended December 1998, 1997 and 1996, respectively. Gateway sales
primarily consist of the sale of fully integrated "turn-key" systems, where the
Company integrates its gateway software with third-party computer hardware and
software components. Sales of IP telephony call management software accounted
for 44%, 11% and 3% of net revenues for the years ended December 31, 1998, 1997
and 1996, respectively. The increase in net revenues for the year ended December
31, 1998 was primarily due to greater sales of the Company's call management
software to its strategic partners, as a result of the commencement of product
distribution by such partners, and expanded end-user deployments. This shift
occurred as the Company's partners began selling its call management products
for use with their gateways. For direct end-user sales, the Company typically
sells its call management software along with its integrated gateway systems as
part of the customer solution. The majority of the Company's sales were

18
<PAGE>

domestic, although the Company's strategic partners distribute its products
internationally.

Net revenues from client software represented 4%, 35% and 72% of net
revenues for the years ended December 31, 1998, 1997 and 1996, respectively.
Client software revenues for 1998 were related to consumer sales of the
Company's WebPhone client software. Client software revenues for 1997 and 1996
were also related to consumer sales of the Company's WebPhone client software
and a product license and distribution agreement with Creative Technology Ltd.
The Company anticipates that net revenues generated from consumer client
software products will remain relatively consistent with the current year, as
the Company's sales and marketing activities are concentrated on its call
management and gateway products.

In September 1998, the Company shipped $2.3 million in software products,
primarily consisting of call management software to Motorola. The Company
deferred recognition of the related revenue as a result of certain exchange
provisions associated with the order. The exchange provisions entitle Motorola
to upgrade and/or exchange the software included in the order for other NetSpeak
products for a period of 18 months. In December 1998, the Company recognized
$988,000 of this deferred revenue as the exchange provisions were terminated for
this portion of the order. The Company expects to recognize the remaining
revenue on this order when no further significant post-delivery obligations
exist, although not later than 18 months from the date of shipment at which time
the exchange provisions expire. The exchange provisions are not applicable to
Motorola's remaining $27.5 million multi-year purchase commitment for NetSpeak's
products; however, certain other conditions remain applicable.

Since its inception, the Company has generated a significant percentage of
its revenues through several of its strategic partners and, as a result, is
highly dependent upon the sales and marketing activities of these partners for
its products. During 1998, four partners accounted for 70% of the Company's net
revenues. During 1998, the Company's most active strategic relationships were
with larger OEMs, like Motorola and Siemens. In an effort to broaden the
distribution of its products and reduce its dependency on a limited number of
large customers, the Company is developing a comprehensive indirect sales
channel, targeting VARs and SIs that concentrate on the computer telephony and
networking industries. As a result of this focus, the Company is in the process
of further refining its products to develop prepackaged solutions that meet
end-users' requirements with minimal customization efforts. In past years, the
Company's development efforts were primarily concentrated on providing its
technology to OEM customers for incorporation into their products, which is
different then the Company's current objectives of developing prepackaged
solutions for end-users.

Although the Company is working to increase the distribution of its
products and diversify its customer base, the Company anticipates that its
revenue stream for at least the first half of 1999 will be heavily dependent
upon key strategic partners. Although Motorola has begun the distribution
process for NetSpeak's products, the Company is uncertain as to the timing of
purchases under the Motorola purchase commitment and receipt of future revenues
from Motorola. During 1998, Siemens was the Company's largest customer, and
while Siemens continues to market the Company's products at the current time,
the Company's exclusivity with Siemens expired in December 1998 and the ultimate
revenues in which Siemens will contribute going forward are also uncertain. In
the event that the Company experiences a significant reduction in revenues from
such partners in the first half of 1999, the Company anticipates that its net
revenues will substantially decrease from the second half of 1998.

During 1998, as part of the Company's efforts to broaden the product
distribution and diversify its customer base, the Company began selling products
to smaller, less established enterprises. These less established customers have
not demonstrated the historical operating results nor do they possess the
financial resources as many of the Company's strategic partners and,
accordingly, the Company's credit risk exposure has increased.

19
<PAGE>

Cost of revenues for the years ended December 31, 1998, 1997 and 1996 were
$1.5 million, or 19% of net revenues, $931,000, or 17% of net revenues, and
$47,000, or 5% of net revenues, respectively. The increases in cost of revenues
were primarily due to a shift in the Company's sales mix towards fully
integrated "turn-key" gateway systems, which include third party hardware and
software components that possess greater costs than the Company's internally
developed software based products. The Company currently intends to continue
marketing integrated gateway systems, however, the market for such products is
highly competitive and the ultimate success of the Company's turn-key gateway
products is unknown at this time. As a result, the sales mix between integrated
systems and software based products is variable from period to period and cost
of revenues may fluctuate significantly as a percent of net revenues in future
periods.

Research and development expenses for the years ended December 31, 1998,
1997 and 1996 were $9.6 million, $5.5 million and $2.3 million, respectively.
The increases in research and development expenses were primarily due to the
expansion of the Company's research and development staff, resulting in greater
personnel costs and equipment depreciation. Also, during 1997, the Company
incurred additional development costs associated with the introduction of a
gateway product utilizing a new hardware platform. All research and development
costs have been expensed as incurred. The Company expects to increase research
and development expenses in future periods in order to perform new product
development and enhancements.

Sales and marketing expenses for the years ended December 31, 1998, 1997
and 1996 were $7.7 million, $2.9 million and $722,000, respectively. The
increases in sales and marketing expenses were primarily due to the expansion of
the Company's sales and marketing staff, resulting in greater personnel costs.
Additionally, during 1998, the Company increased its direct selling expenses in
order to enhance the distribution of its products. The Company also established
an allowance for uncollectible customer accounts as a result of the significant
increase in trade credit sales from 1997, as well as the change in the Company's
customer base as discussed above. Sales and marketing expenses are anticipated
to increase in future periods as the Company seeks to expand its marketing
activities and broaden its sales distribution channels.

General and administrative expenses for the years ended December 31, 1998,
1997 and 1996 were $3.1 million, $1.6 million and $837,000, respectively. The
increases in general and administrative expenses were due to the expansion of
the Company's corporate infrastructure primarily through the addition of
personnel and greater operating expenses. During 1998, the Company also
experienced increased professional service fees, primarily associated with
shareholder and other litigation. General and administrative expenses will
likely increase in future periods upon further expansion of the Company's
infrastructure.

Interest and other income for the years ended December 31, 1998, 1997 and
1996 was $2.5 million, $753,000 and $172,0000, respectively. The increases in
interest income were due to interest earned on net proceeds from the
consummation of a private investment by Bay Networks, in February 1998 as
described below, and the IPO in May 1997.

In connection with the expansion of its strategic partnership with
Motorola in March 1998, the Company entered into a joint development and
technology license agreement with Motorola which includes a $30.0 million
multi-year minimum purchase commitment for the Company's products, subject to
certain conditions. In conjunction with the agreement, Motorola announced a cash
tender offer for 3.0 million shares of the Company's Common Stock at a price of
$30.00 per share. On April 22, 1998, Motorola consummated its tender offer,
acquiring 2,686,470 shares of the Company's Common Stock. Upon the consummation
of the tender offer, Motorola purchased an additional 35,000 shares from two

20
<PAGE>

officers at the tender offer price. The Company incurred $383,000 in other
charges as a result of the cash tender offer by Motorola. Such expenses were
primarily the result of professional fees incurred in connection with the tender
offer.

Income taxes for the years ended December 31, 1998, 1997 and 1996 were
$35,000, $209,000, and $43,000, respectively. Such taxes were the result of
income taxes paid to the Singapore government related to license fees received
pursuant to agreements with Creative.

LIQUIDITY AND CAPITAL RESOURCES

Since its inception, the Company has financed its operations through sales
of equity securities. The Company has raised $65.1 million, net of offering
costs, including $47.2 million in sales of private securities and $17.9 million
in the IPO. As of December 31, 1998, the Company had $44.9 million in cash, cash
equivalents and short-term investments. The Company currently does not have any
available lines of credit.

Net cash used in operating activities during the years ended December 31,
1998, 1997 and 1996 was $9.8 million, $5.9 million and $1.0 million,
respectively. Net cash used in operating activities primarily related to the
Company's continued expansion of its research and development activities, sales
and marketing efforts and the corporate infrastructure.

Net cash provided by investing activities during the year ended December
31, 1998 was $632,000. Net cash provided by investing activities reflected $3.6
million in net sales of short-term investments, which was reinvested in cash
equivalents. This amount was offset by $3.0 million in capital expenditures,
primarily related to purchases of computer and test equipment due to increases
in personnel and the expansion of the Company's system test facilities. Net cash
used in investing activities during the years ended December 31, 1997 and 1996
was $16.1 million and $1.2 million, respectively. For the year ended December
31, 1997 net cash used in investing activities reflects $14.3 million in net
purchases of short-term investments and $1.7 million primarily related to
purchases of computer equipment. Net cash used in investing activities during
1996 primarily related to purchases of equipment.

Net cash provided by financing activities for the year ended December 31,
1998 was $38.6 million. In February 1998, the Company issued 1.3 million shares
of common stock to Bay Networks for $36.8 million, net of offering costs. The
Company also received $1.8 million from exercises of stock options and the
issuance of common stock under its employee stock purchase plan for 681,774 and
6,578 shares of common stock, respectively. Net cash provided by financing
activities for the year ended December 31, 1997 was $20.4 million. On June 3,
1997, the Company closed on the IPO of its Common Stock in which it sold 2.4
million shares of common stock at an initial public offering price of $8.75 per
share, raising net proceeds of approximately $17.9 million. Upon consummation of
the IPO, Motorola exercised a previously granted warrant to purchase 452,855
shares of common stock for $2.5 million. Net cash provided by financing
activities for the year ended December 31, 1996 was $8.1 million and was
primarily attributable to private offerings of equity securities.

The Company has no material commitments other than those under office and
equipment operating leases. As a result of the Company's continued research and
development and sales and marketing efforts, capital expenditures may increase
in future periods primarily through the purchase of computer-related equipment.
The Company anticipates that, based on its present plans and assumptions, the
current cash balances will be sufficient to enable it to sustain its current and
planned operations for a period of at least 12 months. If the Company's
estimates or assumptions prove to be incorrect, the Company may require
additional capital. Additional funding, whether obtained through public or
private debt or equity financing, or from strategic alliances, may not be
available when needed or may not be available on terms

acceptable to the Company. Failure to secure additional financing, if and when
needed, may have a material adverse effect on the Company's business, financial
condition and results of operations.

RECENT ACCOUNTING PRONOUNCEMENT

Statement of Financial Account Standards ("SFAS") No. 131, "Disclosure
about Segments of an Enterprise and Related Information" became effective
January 1, 1998. This Statement supercedes SFAS No. 14 "Financial Reporting for
Segments of a Business Enterprise" and amends SFAS No. 94, "Consolidation of all
Majority-Owned Subsidiaries." This Statement requires annual financial
statements and interim reports to disclose information about products and
services, geographic areas and major customers based upon the management
approach. This approach requires disclosing financial and descriptive
information about an enterprise's reportable segments based on information
management utilizes for making business decisions and assessing performance. At
the present time, management does not segregate business activities in order to
access performance or make decisions about resources to allocate. As such, no
supplemental disclosures are provided.

In December 1998, Statement of Position ("SOP") 98-9, "Modification of SOP
97-2, Software Revenue Recognition, With Respect to Certain Transactions" was
issued. SOP 98-9 amends SOP 97-2, to require recognition of revenue using the
residual method when certain factors of multiple-element transactions exist. SOP
98-9 also amends SOP 98-4 to extend the deferral of the application of certain
passages of SOP 97-2 which limit what is considered vendor-specific objective
evidence necessary to recognize revenue for software licenses in
multiple-element arrangements when undelivered elements exist through fiscal
years beginning on or before March 15, 1999. The Company will adopt SOP 98-9 for
the fiscal year beginning January 1, 2000 and does not believe that the adoption
will have a material impact on the financial position or results of operations
of the Company.

YEAR 2000

The Year 2000 issue is the result of computer programs being written using
two digits rather than four to define the applicable year, consequently, in the
year 2000 such systems may be unable to accurately process certain date-based
information. The Company can potentially be affected by this issue in several
areas including computer systems and software which are utilized in the
Company's infrastructure, the products which the Company develops and sells and
the impact of the Year 2000 issue on the Company's significant vendors,
strategic business partners and customers.

The Company's Year 2000 compliance activities include the identification
and evaluation of both information technology ("IT") and non-IT systems that are
critical to the Company's operations, including systems of its significant
vendors, strategic business partners and customers. Additionally, the Company
will also evaluate the Year 2000 compliance of all of the products that the
Company sells, which include internally developed software and third party
computer related components. Evaluation procedures for the Company's critical IT
and non-IT systems and products for sale consist of performing Year 2000 test
simulations and obtaining Year 2000 compliance documentation for external
products and components, as applicable. In order to evaluate Year 2000
compliance for the Company's significant vendors, strategic business partners
and customers, the Company obtains published Year 2000 compliance documentation
from such entities.

22
<PAGE>

instances of non-compliance. To date, the Company has reviewed many of its third
party hardware and software applications utilized in its infrastructure and have
obtained documentation from the manufacturers certifying Year 2000 compliance.

The Company completed a substantial portion of its testing procedures and
required Year 2000 compliance activities on or prior to December 31, 1998. In
the course of its completed evaluations and testing, the Company did not
encounter any items that were not Year 2000 compliant. However, the Company is
still in the process of completing its remaining testing procedures and
compliance activities, as well as obtaining certification from certain
significant vendors and strategic partners. Should the Company encounter any
items that are not Year 2000 compliant in the course of its remaining evaluation
and testing procedures, the Company will take necessary actions to correct the
matter. To date, costs incurred in evaluating the Company's Year 2000 compliance
activities and corrective actions, where and if required, have not been
material. The Company does not believe that future costs required to complete
its Year 2000 activities will have a material effect on the Company's business,
financial position or results of operations

The Company generates a significant portion of its revenue from several of
its strategic partners and, as a result, revenues could be materially impacted
if the Year 2000 issue adversely affects the operations of these partners. Based
upon the examination of available information, the Company does not believe that
the Year 2000 issue will have a material adverse effect on the operations of its
significant strategic partners and customers.

Notwithstanding the foregoing, there can be no assurance that the Year
2000 compliance activities performed by the Company will adequately identify and
test all of the Company's products and critical internal and external systems to
ensure Year 2000 compliance. Moreover, there can be no assurance that the
systems of the Company's significant vendors, strategic business partners and
customers will be Year 2000 compliant which could result in a material adverse
effect on the Company. As such, the Company is in the process of developing a
comprehensive contingency plan to address situations that may result if the
Company is unable to achieve Year 2000 readiness of its critical systems.

INDEPENDENT AUDITORS' REPORT

To the Board of Directors of NetSpeak Corporation:

We have audited the accompanying consolidated balance sheets of
NetSpeak Corporation and subsidiary (the "Company") as of December 31, 1997 and
1998, and the related consolidated statements of operations, shareholders'
equity and cash flows for each of the three years in the period ended December
31, 1998. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

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

In our opinion, such consolidated financial statements present fairly,
in all material respects, the financial position of the Company as of December
31, 1997 and 1998, and the results of its operations and its cash flows for each
of the three years in the period ended December 31, 1998 in conformity with
generally accepted accounting principles.

NETSPEAK CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION AND OPERATIONS - NetSpeak Corporation ("NetSpeak") and its
subsidiary, Internet Telephone Company ("ITC"), (collectively, the "Company")
develops, markets, licenses, and supports a suite of intelligent software
products and solutions, which enable real-time, concurrent interactive voice,
video and data transmission over packetized data networks, such as the Internet
and local-area and wide-area networks.

The market for the Company's products and solutions is in the early stages
of development and is characterized by rapid technological change, evolving
industry standards, changes in end-user requirements, intense competition by
more established industry participants and frequent new product introductions
and enhancements. As is typical in the case of new and rapidly emerging
technologies, demand and market acceptance are subject to a high level of
uncertainty. Broad acceptance of the Company's products by customers and end-
users is critical to the Company's success and ability to generate revenues. The
Company has a limited operating history upon which an evaluation of the Company
and its prospects can be based. As of December 31, 1998, the Company had an
accumulated deficit of $20.7 million. Due to the Company's limited operating
history and the lack of maturity in the industry, the Company's operating
results are difficult to predict and may fluctuate significantly in the future
as a result of a variety of factors, many of which are outside the Company's
control. These factors include, but are not limited to, the Company's limited
operating history, the Company's ability to develop a recurring revenue stream,
the volume of revenues generated from the Company's strategic partners from
sales of products incorporating the Company's technology, the Company's ability
to attract new partners and develop additional distribution channels for its
products and technology, the effectiveness of the Company's sales and marketing
activities, the need for ongoing product development in an environment of rapid
technological change, the Company's ability to transition from a technology
oriented to a product based company, the acceptance of the Company's products in
the marketplace, the timing and scope of deployments of the Company's products
by customers, technical difficulties with respect to the Company's products or
products in development, the emergence of new competitors in the marketplace,
the timing of new product announcements and releases by the Company and its
competitors, the effect of the Year 2000 issue on customers' purchasing cycles,
the amount and timing of capital expenditures and other costs relating to the
expansion of the Company's operations, the budgeting cycles of potential
customers, the uncertainty of the Internet and Internet Protocol ("IP") based
networks as a medium for real-time voice and video communications, the
uncertainty of future governmental regulation, the Company's ability to manage
growth, obtain patent protection, obtain additional funds and general economic
conditions. The Company believes that it has adequate capital resources to
sustain its operations for a period of at least twelve months.

CONSOLIDATION - The consolidated financial statements include the accounts
of NetSpeak and its wholly-owned subsidiary, ITC. Intercompany transactions and
balances have been eliminated in consolidation.

FINANCIAL INSTRUMENTS - The Company considers all highly liquid
interest-earning investments with contractual maturities of three months or less
to be cash equivalents. Short-term investments generally mature between three
months and three years from the date of purchase. The Company follows the
provisions of Statement of Financial Accounting Standards ("SFAS") No. 115,
"Accounting for Certain Investments in Debt and Equity Securities". Short-term
investments are classified as available-for-sale and are recorded at fair value.
Unrealized gains and losses are reported as a

30
<PAGE>

separate component of shareholder's equity. The Company minimizes its credit
risk associated with cash equivalents and short-term investments by using high
quality credit instruments.

FAIR VALUE OF FINANCIAL INSTRUMENTS - SFAS No. 107, "Disclosure about Fair
Value of Financial Instruments," requires disclosure of the fair value of
financial instruments, both assets and liabilities, recognized and not
recognized in the Consolidated Balance Sheets of the Company, for which it is
practicable to estimate fair value. The estimated fair values of financial
instruments, which are presented herein have been determined by the Company
using available market information. As of December 31, 1997 and 1998, there were
no significant differences between cost and fair value of short-term
investments.

INVENTORIES - Inventories are stated at the lower of cost, determined
utilizing the first-in, first-out method, or market. Inventories consist
primarily of hardware components used in the assembly of integrated systems.

PROPERTY AND EQUIPMENT - Property and equipment is recorded at cost.
Depreciation is provided on the straight-line basis over the estimated useful
lives of the assets. Estimated useful lives range from three to five years.
Routine repairs and maintenance are expensed as incurred.

REVENUE RECOGNITION - The Company generates revenues from product licenses
and fees for services. Product license revenues are generally recognized upon
product shipment, over the license term or upon delivery of permanent
authorization codes, provided that no significant post-delivery obligations
exist and payment is due within one year. Service revenues include fees for
customer maintenance and support and engineering. Service revenues for customer
maintenance and support are recognized ratably over the term of the maintenance
period, which is typically twelve months. Costs related to customer support are
included as a component of sales and marketing. Service revenues for engineering
services are generally recognized when the services are performed. Product
license and service revenues are recognized upon customer acceptance, if
required. Advance payments of product licenses and services are reported as
unearned revenue until all conditions for revenue recognition are met.

In fiscal year 1998, the Company adopted the American Institute of
Certified Public Accountants' Statement of Position ("SOP") 97-2, "Software
Revenue Recognition" and SOP 98-4, "Deferral of the Effective Date of a
Provision of SOP 97-2, Software Revenue Recognition". The adoption did not have
a significant impact on the accompanying consolidated financial statements.

In December 1998, SOP 98-9, "Modification of SOP 97-2, Software Revenue
Recognition, With Respect to Certain Transactions" was issued. SOP 98-9 amends
SOP 97-2 to require recognition of revenue using the residual method when
certain factors of multiple-element transactions exist. SOP 98-9 also
amends SOP 98-4 to extend the deferral of the application of certain passages of
SOP 97-2 which limit what is considered vendor-specific objective evidence
necessary to recognize revenue for software licenses in multiple-element
arrangements when undelivered elements exist through fiscal years beginning on
or before March 15, 1999. The Company will adopt SOP 98-9 for the fiscal year
beginning January 1, 2000. The Company does not believe that the adoption will
have a material impact on its financial position or results of operations.

RESEARCH AND DEVELOPMENT COSTS - Research and development expenditures are
charged to operations as incurred. SFAS No. 86, "Accounting for Costs of
Computer Software to be Sold, Leased or Otherwise Marketed", requires research
and development costs to be capitalized upon the establishment of technological
feasibility. Based on the Company's product development process, technological
feasibility is established upon completion of a working model. Costs incurred
between

31
<PAGE>

completion of the working model and the point at which the product is ready for
general release have been insignificant. All research and development costs have
been expensed as incurred.

ACCOUNTING FOR STOCK BASED COMPENSATION - The Company accounts for its
stock-based compensation in accordance with the provisions of Accounting
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees", and
related interpretations (collectively, "APB 25"). The Company has adopted the
disclosure provisions of SFAS No. 123, "Accounting for Stock-Based Compensation"
which establishes financial accounting and reporting standards for stock-based
employee compensation plans.

INCOME TAXES - Income taxes are provided for based on the treatment
prescribed by SFAS No. 109, "Accounting for Income Taxes". SFAS No. 109 requires
accounting for income taxes based on the asset and liability method and,
accordingly, deferred income taxes are provided to reflect temporary differences
between financial and tax reporting bases of assets and liabilities and net
operating loss carryforwards.

NET LOSS PER SHARE - The Company computes net loss per share under SFAS
No. 128, "Earnings Per Share", which requires a dual presentation of basic and
diluted earnings per share on the face of the income statement. Basic earnings
per share excludes dilution and is computed by dividing income or loss
attributable to common shareholders by the weighted-average number of common
shares outstanding for the period. Diluted earnings per share reflects the
potential dilution that could occur if securities or other contracts to issue
common stock were converted into common stock, but such securities or contracts
are excluded if their effects would be anti-dilutive. The Company excluded stock
options and warrants to purchase 2,935,000 and 3,284,000 common shares from the
weighted-average shares outstanding calculation for the years ended December 31,
1997 and 1998, as their effect was anti-dilutive.

COMPREHENSIVE INCOME - Other comprehensive income refers to revenues,
expenses, gains and losses that under generally accepted accounting principles
are included in comprehensive income but are excluded from net income as these
amounts are recorded directly as an adjustment to shareholders' equity. The
Company's other comprehensive income is comprised of unrealized gains on
investments. The tax benefit or expense, as well as any reclassifications
related to components of other comprehensive income were not significant.

RISKS AND UNCERTANTIES - The Company's operating results and financial
condition have varied and may in the future vary significantly depending on a
number of factors. The following factors may have a material adverse effect upon
the Company's business, financial condition and results of operations.

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.

RELIANCE UPON STRATEGIC RELATIONSHIPS - Since its inception, the Company
has generated a significant percentage of its revenues through several of its
strategic partners and, as a result, is highly dependent upon the sales and
marketing activities of these partners for its products.

TECHNOLOGICAL ADVANCEMENTS AND COMPETITION - The market for the Company's
products is in the early stages of development and is characterized by rapid
technological change, evolving industry standards, changes in end-user
requirements, intense competition by more established industry

32
<PAGE>

participants and frequent new product introductions and enhancements. As a
result, the timing of demand and market acceptance of the Company's products and
technologies is subject to a high degree of uncertainty, causing further
uncertainty regarding the Company's ability to obtain a consistent revenue
stream in the future.

RECENT ACCOUNTING PRONOUNCEMENT - SFAS No. 131, "Disclosure about Segments
of an Enterprise and Related Information" became effective January 1, 1998. This
Statement supercedes SFAS No. 14 "Financial Reporting for Segments of a Business
Enterprise" and amends SFAS No. 94, "Consolidation of all Majority-Owned
Subsidiaries." This Statement requires annual financial statements and interim
reports to disclose information about products and services, geographic areas
and major customers based upon the management approach. The management approach
requires disclosing financial and descriptive information about an enterprise's
reportable segments based on reporting information the way management organizes
the segments for making business decisions and assessing performance. At the
present time, management does not segregate business activities in order to
access performance or make decisions about resources to allocate. As such, no
supplemental disclosures are provided.

RECLASSIFICATIONS - Certain reclassifications to the prior years'
Consolidated Financial Statements have been made to conform to the current year
presentation.

In the first quarter of 1996, the Company sold 1,204,000 shares of common
stock for $2.50 per share in a private placement raising $2,992,000, net of
offering costs. In January 1996, the Company issued an option to purchase
250,000 shares of common stock, which expires in January 2003, for $2.50 per
share to a consulting firm that assisted the Company with its private placement.
The fair value of this option, $271,000, was recorded as a cost of the offering.

In June 1996, the Company issued 207,679 shares of common stock to
Creative Technology Ltd. ("Creative") raising an aggregate of $944,000, net of
offering costs. The Company also issued Creative a 21 month warrant to purchase

share. In 1998, Creative exercised the warrant upon meeting certain
predetermined product distribution requirements.

In August 1996, the Company issued 769,853 shares of common stock and a 72
month warrant to purchase up to an additional 452,855 shares of common stock at
a price of $5.50 per share to Motorola, Inc. ("Motorola") raising $3,994,000,
net of offering costs.

On June 3, 1997, the Company closed on the initial public offering of its
Common Stock. The Company offered and sold 2,400,000 shares of the common stock
at an initial public offering price of $8.75 per share, raising proceeds, net of

agreement with Bay Networks, Inc. In conjunction with the agreement, on February
3, 1998, the Company issued 1,334,171 shares of common stock to Bay Networks,
Inc., raising $36,753,000, net of offering costs.

On June 18, 1998, the Company's shareholders approved an increase in
authorized common stock from 25,000,000 shares, $0.01 par value per share, to
75,000,000 shares, $0.01 par value per share.

During 1998, the Company received $1.8 million from the exercise of
681,000 stock options, of which 532,000 were exercised by employees and 149,000
by non-employees.

34
<PAGE>

The Company has authorized 1,000,000 shares of preferred stock, $0.01 par
value. No shares of preferred stock have been issued.

5. STOCK BASED COMPENSATION AND EMPLOYEE STOCK PURCHASE PLAN

STOCK OPTION PLAN - The Company's 1995 Stock Option Plan (the "Plan") was
amended on June 18, 1998 to increase the number of shares reserved for issuance
thereunder from an aggregate of 2,700,000 shares to an aggregate of 5,500,000
shares. Under the Plan, the Company may grant stock options to key employees,
consultants, officers and directors. The exercise price of each option must not
be less than the fair market value of the Company's stock on the date of grant
and an option's maximum term is 10 years. Incentive stock options vest equally
over three years beginning on the first anniversary date of the grant, while
non-statutory options vest over various periods.

A summary of the status of the Plan as of December 31, 1996, 1997 and
1998, and changes during the periods ended on those dates is presented below:

</TABLE>

The fair value of each employee stock option grant has been estimated on
the date of grant using the Black-Scholes option pricing model. The weighted
average fair value of employee stock options granted in 1996, 1997 and 1998 was
$0.83, $4.69 and $6.91, respectively. The following assumptions were used:

DECEMBER 31,

1996 1997 1998
-------------- -------------- --------------
Expected life 5 years 5 years 5 years
Interest rate 5.39% - 6.77 % 6.00% 6.00%
Volatility 0.10% 60% 56%
Dividends None None None

STOCK PURCHASE PLAN - The NetSpeak Employee Stock Purchase Plan ("ESPP")
was adopted by the Board of Directors and approved by the Company's shareholders
on June 18, 1998. The ESPP provides for the issuance of a maximum of 400,000
shares of Common Stock to all eligible employees of the Company. To participate
in the ESPP, an employee must authorize the Company to deduct an amount not more
than 15% of a participant's compensation from his or her pay during six-month
periods (each a "Purchase Period"). The exercise price for the Purchase Period
is 85% of the lesser of the market price of the Common Stock on the first or
last business day of the Purchase Period. The Company issued 6,578 shares, at
$5.58 per share, in 1998 under the ESPP.

STOCK COMPENSATION PLANS - As of December 31, 1998, the Company has two
stock-based compensation plans, which are described above. The Company applies
APB 25 in accounting for its plans. Accordingly, no compensation expense has
been recognized for options granted under the Plan or for the ESPP. Had
compensation expense been determined based upon the fair value at the grant
dates for the awards under those plans consistent with the methods prescribed by
SFAS No. 123, the Company's net loss and net loss per share, on a pro forma
basis, would have been:

6. COMMITMENTS

The Company leases its office facility and certain equipment under
operating leases with remaining lease terms in excess of one year. Future
minimum lease payments as of December 31, 1998 are as follows (in thousands):

YEAR ENDING DECEMBER 31,

======

Rent expense for the periods ended December 31, 1996, 1997 and 1998 was
approximately $67,000, $168,000 and $346,000, respectively.

In September 1996, the Company established a 401(k) deferred compensation
plan for all employees meeting certain service requirements. The Company matches
employee contributions to the plan at its discretion. The Company's
contributions during the years ended December 31, 1996, 1997 and 1998 were $0,
$19,000 and $37,500, respectively. The administrative costs of the plan are paid
by the Company.

The Company has entered into employment agreements with five officers with
base salaries aggregating $985,000 annually. The terms of these agreements are
for two years, with renewal provisions.

The Company has entered into Indemnification Agreements with each of the
existing directors and officers, which provides for the maximum indemnification
permitted by law.

7. CONTINGENCIES

LITIGATION - The Company may, from time to time, be involved in certain
legal actions arising in the ordinary course of business. In the opinion of
management, the outcome of such actions known to date will not have a material
adverse effect on the Company's financial position or results of operations.

At present, there are few laws or regulations that specifically address
access to or commerce on the Internet. The increasing popularity and use of the
Internet, however, enhances the risk that the governments of the United States
and other countries in which the Company sells or expects to sell its products
will seek to regulate computer telephony and the Internet with respect to, among
other things, user privacy, pricing and the characteristics and quality of
products and services. The Company is unable

37
<PAGE>

to predict the impact, if any, that future legislation, legal decisions or
regulations may have on its business, financial condition or results of
operations.

YEAR 2000 (unaudited) - The Year 2000 issue is the result of computer
programs being written using two digits rather than four to define the
applicable year, consequently, in the year 2000 such systems may be unable to
accurately process certain date-based information. The Company can potentially
be affected by this issue in several areas including computer systems and
software which are utilized in the Company's infrastructure, the products which
the Company develops and sells and the impact of the Year 2000 issue on the
Company's significant vendors, strategic business partners and customers.

The Company has examined the architecture of its products, as well as
relevant documentation related to third party components that are integrated
into these products. Based upon these examinations, the Company's products
appear to be Year 2000 compliant. In order to validate these preliminary
findings, to date the Company has completed test procedures on certain of its
internally developed products, as well as the associated third party components.
The results of these tests do not indicate any instances of non-compliance. To
date, the Company has reviewed many of its third party hardware and software
applications utilized in its infrastructure and have obtained documentation from
the manufacturers certifying Year 2000 compliance.

38
<PAGE>

the systems of the Company's significant vendors, strategic business partners
and customers will be Year 2000 compliant which could result in a material
adverse effect on the Company. As such, the Company is in the process of
developing a comprehensive contingency plan to address situations that may
result if the Company is unable to achieve Year 2000 readiness of its critical
systems.

8. INCOME TAXES

The Company's provision for income taxes consists of the following:

DECEMBER 31,
1996 1997 1998
------ ------ ------
(in thousands)
Current - Foreign $ 225 $ 60 $ 16
Deferred - Foreign (182) 149 19
----- ----- -----
$ 43 $ 209 $ 35
===== ===== =====

Income taxes were attributable to income taxes paid to the Singapore
government related to license fees received pursuant to an agreement with
Creative.

Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and their income tax bases. As of December 31, 1997 and 1998, the
Company had deferred tax assets as follows:

DECEMBER 31,
-----------------------
1997 1998
-------- --------
(in thousands)
Deferred tax assets:
Unearned revenue - foreign ..... $ 33 $ 14
Fixed assets ................... (126) 483
Other .......................... 140 527
Net operating loss carryforwards 3,083 9,406
Valuation allowance ............ (3,097) (10,416)
-------- --------
Net deferred tax asset .... $ 33 $ 14
======== ========

The valuation allowance has been established to reduce the deferred tax
asset to an amount that is more likely than not to be realized, and is based on
the uncertainty as to the utilization of the net operating loss carryforwards
due to the Company's short operating history and losses to date.

As of December 31, 1998, the Company had approximately $24,400,000 and
$20,200,000 of federal and state net operating loss carryforwards, respectively,
available to offset future taxable income; such carryforwards begin to expire in
2009. Under the Tax Reform Act of 1986, the amounts of and benefits from net
operating losses carried forward may be impaired or limited in certain
circumstances. Events which may cause limitations in the amount of net operating
losses that the Company may utilize in any one year include, but are not limited
to, a cumulative ownership change of more than 50% over a three

39
<PAGE>

year period. As of December 31, 1998, the effect of such limitations, is not
expected to be material.

The Company's income tax provisions differed from the statutory federal
rate of 34.0% as follows:

DECEMBER 31,
--------------------------------
1996 1997 1998
-------- -------- --------
Statutory rate applied to
earnings before income taxes ... 34.0 % 34.0 % 34.0 %
State rate net of federal benefit 3.6 3.6 3.6
Foreign taxes ..................... (1.5) (4.3) (0.3)
Valuation allowance ............... (37.6) (37.6) (37.6)
------- ------- -------
Income tax provision .............. (1.5)% (4.3)% (0.3)%
======= ======= =======

9. RELATED PARTY TRANSACTIONS

On April 22, 1998, Motorola consummated a cash tender offer, acquiring
2,686,470 shares of the Company's Common Stock. The Company incurred $383,000 in
other charges as a result of the cash tender offer. Upon consummation of the
tender offer, Motorola purchased an additional 35,000 shares of common stock
from two officers at the tender offer price. As of December 31, 1998, Motorola
owned 30.9% of the total outstanding common shares of the Company.

During 1998, Motorola accounted for 17% of net revenues. In addition,
Creative, a 1.4% shareholder, accounted for 44%, 47% and 8% of net revenues for
the years ended December 31, 1996, 1997 and 1998, respectively.

The Company has advanced an aggregate $500,000 to an officer of the
Company, which is evidenced by interest-bearing promissory notes. The Company
will forgive one third of the principal amount of the loan, and accrued interest
thereon, on the first, second and third anniversary of the related promissory
notes, provided that the officer continues to be employed by the Company on such
dates. In the event that the officer leaves the Company or is terminated with
cause, any unforgiven principal amount of the loan, together with accrued
interest thereon, will be payable in full. The Company is providing for a
reserve on this loan through a monthly pro-rata charge to compensation expense.

10. CONCENTRATION RISK

In addition to Motorola and Creative, the Company had net revenues
attributable to individual customers in excess of 10% of total net revenues as
follows:
