PART I

ITEM 1. BUSINESS

OVERVIEW

General

NetSpeak develops, markets, licenses, and supports a suite of
intelligent software products and systems 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 ("LANs" and "WANs",
respectively). NetSpeak's products allow organizations to build new voice and
video-enabled communications networks, or to add these communications
capabilities to their existing network infrastructure. The Company's software
uses its patent-pending virtual circuit switching architecture and its
intelligent call routing and management software to provide gateways between
packetized data networks and traditional circuit switched voice transmission
networks to enable users to transparently communicate with each other on a
point-to-point basis. NetSpeak's technology integrates into packetized data
networks a variety of features and functions commonly found in traditional voice
transmission networks, and expands a network's functionality by offering
additional features such as concurrent voice and data transmission and video
conferencing. The Company has focused its efforts on developing its suite of
products and systems to meet the stringent requirements of telecommunications
carriers which include at a minimum scalability, reliability , interoperability
and redundancy as well as a number of other systems management, remote
operations, administration and maintenance features commonly found in carrier
grade technology.

and distributed by its strategic partners through various distribution channels.
To date, the Company has established strategic alliances with Motorola, Inc.
("Motorola"), Bay Networks, Inc. ("Bay Networks"), Siemens Telecom Networks
("Siemens"), Creative Technology Ltd. ("Creative") and several other industry
leaders.

The Company is also directly targeting common carriers and other
end-users of its products and systems. The Company's customers in this market
include MCI Communications Inc. ("MCI"), Networks Telephony Corporation ("NTC"),
a subsidiary of Infonet Services Corporation, and BellSouth Telecommunications,
Inc. ("BellSouth") among others.

The Company's strategy is to become an industry leader in providing
business solutions for concurrent real-time interactive voice, video and data
transmission over packetized data networks. The Company intends to achieve its
goal by (i) expanding and strengthening its existing and establishing new
strategic alliances to facilitate technological acceptance and enhance the
marketing and distribution of its products and systems; (ii) expanding its
internal marketing and sales efforts; and (iii) continuing research and
development to enhance existing product applications, as well as develop new
applications.

Recent Development

On March 18, 1998, NetSpeak and Motorola expanded their existing
strategic alliance to include joint development and licensing of technology as
well as a $30 million multi-year minimum purchase commitment by Motorola for
NetSpeak's products.

Under a joint development and licensing agreement pursuant to which the
parties will seek to join their technologies to enable Internet Protocol ("IP")
multimedia communications on wireless networks, NetSpeak granted Motorola an
exclusive license to develop RF (Radio Frequency) products using NetSpeak's
technology. Motorola will be able to include NetSpeak's technology in all
wireless infrastructure (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. Additionally, NetSpeak
has granted Motorola a non-exclusive license for the manufacture and sale of
NetSpeak's products.

As part of this expanded relationship, Motorola will seek to increase
its equity investment in NetSpeak by means of a cash tender offer for 3.0
million shares of NetSpeak Common Stock, representing approximately 27.7% of
NetSpeak's outstanding shares not owned by Motorola at a purchase price of
$30.00 per share. Motorola has also agreed to purchase 35,000 shares of NetSpeak
Common Stock from two officers. The offer will be made pursuant to a tender
agreement and certain other related agreements and definitive offering documents
to be filed with the Commission. The offer is conditional upon the tender of a
minimum number of shares and receipt of regulatory approvals as well as certain
other conditions to be set forth in the offering documents. Officers and
directors may participate in the offer, although the Company has not been
advised as to the number of shares that officers and directors will tender.

Assuming a fully subscribed tender, Motorola will own approximately
28.2% of NetSpeak's common stock on a fully diluted basis upon completion of the
offering. In addition, NetSpeak's Board of Directors will be increased from
seven up to ten members with Motorola acquiring up to two additional seats on
the Board of Directors (pending consummation of the offer) and certain
management shareholders have agreed to vote in favor of the elections of such
directors. Motorola has also agreed for three years, subject to certain
exceptions, not to buy or offer to buy additional NetSpeak shares or seek to
effect a change of control of NetSpeak without the consent of NetSpeak's Board
of Directors.

INDUSTRY BACKGROUND

4
<PAGE>

Two fundamentally different switching technologies exist that enable
digital communications: circuit switching and packet switching. Since the
differing performance requirements for voice transmission and data transmission
impose different design priorities, historical development of voice
communication systems such as the telephone, and its related business systems,
such as a corporate business telephone system ("PBX") and automatic call
distribution ("ACD"), has centered on circuit switching technology, while that
of data communications systems such as LANs and WANs and the Internet have
primarily relied upon packet switching technology. As a result, separate
cultures and networking fabrics have evolved for the design, development,
application, and support for real-time voice communications (circuit switched
networks) and non real-time data transmission (packetized data networks).

High quality, real-time interactive voice communications must emulate a
reasonable approximation of a face to face conversation between two
geographically separated people. To accomplish this, the modulated signal
representing the spoken words must (i) have enough information to re-create a
recognizable voice by using a fixed bandwidth, (ii) be delivered with minimum
delay by using a dedicated path in order not to impede interactive
communications, (iii) be delivered at a constant rate in order to avoid
distortion to the ear of the listener and (iv) not be subject to significant
loss of information en route. These capabilities are inherent in circuit
switched networks such as the public switching telephone network (the "PSTN")
but must be created when using packetized data networks for voice transmission.

The design of private Intranets such as LANs and WANs, and that of the
Internet generally is fundamentally different from the architecture of
conventional voice transmission networks. Each of these packetized data networks
breaks down data into a series of small, discrete packets for transmission. Each
packet of data travels independently through the network to the destination
address where application software reassembles the packets to recreate the
original data set. As currently designed, packetized data networks handle
congestion by discarding or delaying packets or by sending packets from the same
source along different pathways, which can result in packets which were sent in
sequence arriving out of order. If the transmitted data packet represents
real-time voice, the listener may perceive a gap or "choppiness" as a result of
missing, late-arriving or out-of-sequence packets.

As the work environment increasingly demands faster access to greater
volumes of information from multiple sources, the individual capabilities of
separate circuit switched and packetized data networks are being seriously
challenged. The response from circuit switch manufacturers has been the
development of new switching system architectures that make it easier for
separate, application-specific software to control the circuit switching
function, and to seek to maintain the market value of circuit switched systems
by increasingly using voice applications processes to offer additional services
such as voice mail, interactive voice response and ACD. The intensity of
technical activity involved in further integrating the interaction of specific
application processes and information delivery systems has given computer
telephony integration the status of a technology in its own right.

A growing number of businesses and other organizations have recognized
the Internet as a network which enables an enhanced form of public
communication. In order to create conditions amenable to satisfactory commerce
and business communications on the Internet, the same kinds of services offered
in communicating with customers via traditional voice transmission networks such
as the PSTN must be available when communicating with customers via the
Internet.

The Internet represents primarily an access to potential markets that
cannot be efficiently exploited if a separate, parallel infrastructure is
required for its service. Its evolution, however, has supported the development
of technologies such as those of NetSpeak that have made feasible the
integration of the two different architectures of circuit switched and
packetized data networks in such a way that communications between the two are
meaningful, and such that each can selectively take advantage of the special
capabilities of the other.

5
<PAGE>

There are many applications currently utilizing traditional telephony
that could benefit from the capabilities available from data communications
networks such as contemporaneous transmission of data and voice over a single
system. The general difficulty in adapting some of these capabilities to the
circuit switching environment lies in the limited expertise of those in the
traditional telephony environment in developing and applying the desired
adaptations on the one hand, and the limited systems and application expertise
necessary for those in the packetized data network environment to recognize the
problems, understand the opportunities, or design appropriate solutions on the
other.

The introduction and rapid development of IP technology revolutionized
the deployment and use of data communications networks such as the Internet.
Even though this technology is in its infancy, it is already creating a growing
demand for the integration of features and functions available in traditional
voice communications networks into the packetized data network environment.

NETSPEAK'S CORE COMMUNICATIONS TECHNOLOGY

NetSpeak has developed a core communications technology which addresses
the challenges associated with real-time interactive voice transmission over
packetized data networks. NetSpeak's technology surmounts the difficulties
inherent in real-time interactive voice transmissions in the packetized data
network environment and permits the integration into this environment of
features commonly found in traditional voice transmission networks, as well as
enabling the concurrent voice, video and data transmission over packetized data
networks, thereby expanding the functionality of packetized data networks. For
example, NetSpeak's core communications technology will permit a call placed
over the Internet to the technical support department of a customer to be
transferred from the Internet to the customer's LAN, route the call to the next
available service agent, and provide the service agent with information
regarding the call. NetSpeak's core communications technology is the platform
utilized in all of its products and systems. Among other features and functions,
NetSpeak's core communications technology:

/bullet/ permits encrypted, two-way voice transmission. NetSpeak's software
manages different types of information streams, using different
priorities, to optimize use of available bandwidth capacity, while
providing the most sensitive applications such as voice transmission
with first priority to that capacity, thereby minimizing the choppiness
typically associated with voice transmission over packetized data
networks. Encryption allows for secure communications even over
packetized data networks, such as the Internet;

/bullet/ allows users to connect to other users in a point-to-point fashion,
rather than through an intermediate routing mechanism. NetSpeak's
intelligent virtual switching technology implements a patent-pending
technique for address resolution which translates circuit switching
addresses to IP network addresses, thereby eliminating the need to know
an end-user's packetized network address;

/bullet/ provides dynamic and fixed IP address mixing which can create networks
that carry traffic from both fixed-address networks such as a LAN and
dynamically-assigned address networks such as the Internet to form a
seamless communications network (a "network of networks")
infrastructure. This infrastructure can operate over any physical
network that supports IP;

/bullet/ uses a common object-oriented code base that allows the technology to
be integrated into other NetSpeak and third party products;

/bullet/ operates on multiple operating systems and can be ported to various
operating platforms.

NetSpeak is conducting ongoing research and development to further
enhance its core technology, by continuing to develop additional applications
and features and functionality in its products.

NETSPEAK'S STRATEGY

The Company's goal is to use its core communications technology to
become an industry leader in providing business solutions for concurrent
real-time interactive voice transmission over packetized data networks while
seemlessly integrating the features and functions of existing voice transmission
networks into the packetized data networking environment. The Company's strategy
includes the following key elements:

ESTABLISH STRATEGIC ALLIANCES TO FACILITATE TECHNOLOGICAL ACCEPTANCE

In order to facilitate and accelerate the acceptance of NetSpeak's
technology, as well as enhance marketing and distribution of its products
and systems, the Company has established a number of strategic alliances
with various leaders in the telecommunications and networking industries.
The Company intends to leverage its partners' extensive existing sales and
distribution channels to accomplish this objective. Pursuant to certain of
these agreements, either the Company's technology is integrated into
products which are marketed by its strategic partners or the Company' s
products and systems are marketed and distributed by its strategic partners
through various distribution channels. The Company believes that these
strategic alliances also offer access to its partners' leading edge
technologies. To date, the Company has established strategic alliances with
Motorola, Bay Networks, Siemens, Creative and several other industry
leaders. The Company intends to expand and strengthen existing and
establish additional strategic alliances.

EXPAND INTERNAL MARKETING AND SALES EFFORTS

The Company is developing an infrastructure to facilitate distribution
of the Company's technology, products and services. The Company is
presently building an in-house sales force and expanding its direct
marketing and sales efforts to service providers, including
telecommunications and other common carriers, large business enterprises,
governmental and educational entities, as well as original equipment
manufacturers ("OEMs"), systems integrators ("SIs") and value-added
resellers ("VARs").

EDUCATE THE MARKETPLACE

Given the historical use of different infrastructures for voice and
data transmission, NetSpeak believes that it needs to continue the
education process to our potential customer base on how our IP telephony
technology can facilitate the consolidation of these infrastructures by
integrating capabilities and features commonly found in traditional voice
transmission networks into the packetized data network environment. The
Company is expanding the number of marketing programs it conducts in this
regard, including advertising in trade journals and similar media,
attendance at industry trade shows and direct mail campaigns. In addition,
the Company has been and continues to be involved in industry wide standard
setting bodies, such as the Massachusetts Institute of Technology's ("MIT")
ITC (Internet Telephony Interoperability Consortium) consortium, VoIP
(Voice on IP) forum, IMTC (Interoperable Multimedia Teleconference), and
VON (Voice on the Net) Coalition.

CONTINUE RESEARCH AND DEVELOPMENT

The Company intends to extend the functionality and uses of its core
communications technology by continuing to invest in research and
development. The Company believes that it can further improve its
technology which will allow it to enhance its existing product applications
as well as develop new

<PAGE>

applications.

PRODUCTS AND SYSTEMS

NetSpeak's products and systems consist of four principal groups:
gateway systems, IP telephony server products, call-center systems and client
software. The Company has focused on developing its suite of products and
systems to meet the stringent requirements of telecommunications carriers which
include scalability, reliability, interoperability and redundancy as well as a
number of other systems management, remote operations, administration and
maintenance features. NetSpeak's products and systems combine its various
intelligent software modules to provide applications that furnish each
particular product's desired features and functions. The Company's initial
product offering was its WebPhone client software, released in February 1996.
Throughout most of 1997, the Company's carrier-grade gateway systems and IP
telephony server products were in a limited release to certain strategic
partners and key customers and were made commercially available in the fourth
quarter of 1997. The Company anticipates commercial release of its initial call
center products in the second quarter of 1998.

GATEWAY SYSTEMS

Gateway products are designed as transition points between two
different network types, such as between the PSTN and the Internet. Gateway
products convert regular voice transmission to or from the compressed data
packets that travel over packetized data networks. Gateway products can be
used to bring packetized voice transmission into existing voice
transmission networks such as a PBX or translate voice from the voice
transmission network to a user's Intranet.

NetSpeak's WebPhone Gateway eXchange ("WGX") is PC-based and offers up
to 96 and 120 ports in a single chassis with digital T1 and E1,
respectively, and standard analog PSTN network interfaces. NetSpeak is also
developing a gateway product line based on the Company's proprietary
hardware design which is targeted at the specific requirements of
telecommunications carriers. This product line will offer increased port
densities as well as optimize the efficiency at which the gateway
functions.

IP TELEPHONY SERVER PRODUCTS

NetSpeak IP telephony server software provides intelligent system and
network management functions for IP telephony networks. These modules
perform complex call routing by controlling the connection process between
users, manage network operations, coordinate detailed user activity and
account billing, and provide other value-added features and functions to
users.

NetSpeak's software modules can be combined to construct various types
of voice transmission networks. These software modules include the Gateway
Routing Server which dynamically manages call routing between multiple
gateways deployed on a network; the Subscriber Account Manager, maintains
customer account records including prepaid account balances; the Event
Management Server, provides system operations management and enables
real-time billing; the Credit Processing Server, provides real-time
collection and customer account management for credit card transactions;
the Connection and Information Services Servers, which are responsible for
finding the destination party and coordinating the connection between
users; the ACD Server module, which is the key to NetSpeak's call center
systems (described below); and the Control Center module, which is the
management control software for all of NetSpeak's products. A variety of
other support modules which will offer further valued-added features and
functions are under development.

CALL CENTER SYSTEMS

8
<PAGE>

Call center systems are generally used by customer service departments
within corporations for a wide variety of communications functions, such as
sales, service and technical support between such companies and their
customers. Call center systems route calls to individual customer service
agents based on factors such as agent skills or agent call volume, and
provide the agents with information about incoming calls in order to
facilitate customer interaction.

The Company's ITEL Call Center allows a customer to construct a call
center entirely in a packetized data network environment utilizing only a
PC as the call center agent's user interface. The system allows for
transmission of voice and video based calls.

The WebPhone Enterprise ACD integrates the capabilities of the ITEL
Call Center with the power of WGX for translating calls from the PSTN and
converting them to packetized voice for distribution to an agent's PC. As a
result, all caller traffic arrives at the agent's desktop in a uniform
format, whether originated over the Internet, the user's Intranet or the
PSTN.

CLIENT SOFTWARE PRODUCTS

NetSpeak's client or end-user software products include the standard
NetSpeak WebPhone, NetSpeak's Internet telephone software product, which
was the first NetSpeak client product on the market. WebPhone is the basis
of the NetSpeak client software products including the Agent and Mini
WebPhones, which are key components of NetSpeak's call center systems.

STRATEGIC ALLIANCES

In order to facilitate and accelerate the acceptance of NetSpeak's
technology, as well as enhance marketing and distribution of its products and
systems, the Company has established a number of strategic alliances with
leaders in various segments of the telecommunications and networking industries.
The Company intends to leverage its partners' extensive existing sales and
distribution channels to accomplish this objective. Pursuant to certain of these
agreements, either the Company's technology is integrated into products which
are marketed by its strategic partners or the Company' s products and systems
are marketed and distributed by its strategic partners through various
distribution channels. The Company believes that these strategic alliances also
offer access to its partners' leading edge technologies. To date, the Company
has established strategic alliances with Motorola, Bay Networks, Siemens,
Creative and several other industry leaders. The Company intends to expand and
strengthen its existing and establish additional strategic alliances.

The following highlights companies with which NetSpeak is currently
participating in strategic relationships:

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 connection with the investment by Motorola, the Company granted
to Motorola a right of first negotiation on licenses of NetSpeak's
technology as it applies to the cellular, cable and wireless communications
industries. A designee of Motorola serves on the Company's Board of
Directors. In March 1998, the Company and Motorola agreed to significantly
expand their strategic relationship as described in "Overview - Recent
Development" above.

BAY NETWORKS

<PAGE>

In January 1998, the Company established a strategic relationship with
Bay Networks. Under the agreements entered into with Bay Networks, NetSpeak
will integrate its technology into certain of Bay Networks' router and
remote access products, and the companies will jointly develop products
employing NetSpeak's technology. Bay Networks will also resell NetSpeak's
gateway and IP telephony server products. In connection with this
agreement, the Company issued approximately 1.3 million shares of common
stock to Bay Networks for $36.8 million, net of offering costs.
Additionally, the Company has agreed not to enter into any new agreements
with certain of Bay Networks' competitors to resell NetSpeak's products for
a period of one year and not to provide its source code to such competitors
for a period of three years.

SIEMENS

In June 1997, the Company established a strategic partnership with
Siemens. In November 1997, the Company expanded its agreement with Siemens
and, as a result, Siemens will market NetSpeak's carrier-grade gateway
products and IP telephony server products and include NetSpeak's technology
and applications on the Siemens gateway platform.

CREATIVE

In June 1996, the Company entered into a strategic alliance with
Creative. Pursuant to the agreements, Creative made a minority investment
in the Company and the Company granted Creative a worldwide exclusive
license to market, distribute and bundle an Internet telephone based on the
Company's WebPhone client software product under the Creative brand name in
the retail distribution channel until August 2000. NetSpeak and Creative
are also jointly developing other multimedia Internet-related applications
which use both companies proprietary technology. In conjunction with this
development, the Company has licensed its technology to Creative through
December 2006. Creative has a right to market any jointly developed
applications exclusively for up to seven months.

OTHER ALLIANCES

The Company has also entered into strategic relationships with a
number of other companies such as Telstra R&D Management Pty, Ltd , a
subsidiary of Telstra Corporation Ltd., the Australia telephone company, to
jointly develop and market a gateway utilizing SS7 signaling and NetSpeak's
IP telephony technology. The Company has OEM and distribution agreements
with ACT Networks, Inc., Fujitsu Business Communications Systems and the
Switching Systems Division of Rockwell International Corporation in which
the Company is integrating its software into the companies' proprietary

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, 1997. Research and development expenses were approximately $5.5
million for the year ended December 31, 1997 and approximately $2.3

11
<PAGE>

million and $203,000 in 1996 and 1995, respectively. All of the Company's
research and development costs have been expensed as incurred, including
purchased research and development of $557,000 in connection with the
acquisition of Internet Telephone Company. The Company intends to significantly
increase research and development expenses in future periods to perform product
enhancements and new product development in order to seek to establish and
maintain a competitive advantage.

COMPETITION

The Company anticipates that competition in the IP telephony software
market, which includes gateways, IP telephony network management systems and
applications will increase and become intensely competitive in the future.
Currently, the Company faces competition from different companies across each of
its product lines. The Company competes with companies such as Lucent
Technologies, Inc., VocalTec Communications Ltd., Vienna Systems Corporation,
Clarent Corporation and Inter-tel, Incorporated. The Company anticipates it will
also face further competition in all market segments from companies in the
telecommunications and computer industries which decide to market competitive
products or systems. Although the Company faces increased competition from this
segment, these companies represent existing and potential future customers and
strategic partners. In addition, the Company also competes with manufacturers of
hardware-based business systems.

Many of the Company's current and potential competitors have longer
operating histories, greater name recognition, larger customer bases and
significantly greater financial, technical and marketing resources than the
Company. The Company believes that the principal competitive factors affecting
its potential success include development, time-to-market, quality, performance,
product features; such as flexibility, scalability, interoperability,
functionality and ease of use; price, customer service and support,
product/vendor reputation and the overall effectiveness of its sales and
marketing efforts. Certain of these competitors may be existing or potential
strategic partners.

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, enhance 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 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
technology and products. The Company has filed 19 U.S. utility patent
applications and one Patent Cooperation Treaty patent application relating to
various aspects of the Company's software, its virtual circuit switching
architecture, and techniques for resolving dynamically assigned Internet
Protocol addresses. 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.

Elk Industries has asserted, in a letter to NetSpeak, just prior to the
November 1996 expiration of U.S. Patent No. 4,128,773, owned by Elk Industries,
that the Company's WebPhone client software product infringed the now expired
patent. Given the initial distribution of the Company's WebPhone client software
prior to expiration of the asserted patent, the Company believes any potential
liability related to the allegation will not have a material effect on the
Company's financial position or results of operations. In May 1997, the Company
received a letter from e-Net, Inc. ("e-Net"), alleging that the Company's
WebPhone product infringes U.S. Patent No. 5,526,353 owned by e-Net. Although
there can be no assurance of the outcome of this uncertainty, following an
analysis of the subject patent and the WebPhone product, management believes the
allegations are without merit and that any potential liability related to
e-Net's allegations will not have a material effect on the Company's financial
position or results of operations.

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 which 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, 1998, the Company employed 109 persons, 63 in
research and development, 30 in sales and marketing and 16 in administration and
finance. The Company anticipates increasing its staff significantly 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.

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. The Company believes that its future success depends
in part on its continued ability to hire, assimilate and retain qualified
personnel.

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 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 $1,587,000 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

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

INTRODUCTION

The Company released its first product in February 1996 and, for
accounting purposes, emerged from the development stage during 1996. The Company
generates revenues from the sale of products, licenses and fees for services.
The Company's products are licensed primarily to service providers, including
telecommunications carriers, cable companies and other common carriers, business
enterprises, OEMs, SIs, VARs and directly to individual client software
end-users. Service revenues consist of customer support, maintenance and
engineering fees.

Product and license revenues are generally recognized upon shipment,
provided that there are no significant post-delivery obligations and that
payment is due within one year. If customer acceptance is required, revenues are
recognized upon customer acceptance. Customer support revenues are recognized
over the term of the support period, which is typically one year. Engineering
fees are recognized upon customer acceptance or over the period in which
services are provided if customer acceptance is not required. All research and
development costs to date have been expensed as incurred.

The Company has only a limited operating history upon which an
evaluation of the Company and its prospects can be based. As of December 31,
1997, the Company had an accumulated net loss of $8.6 million. The limited
operating history of the Company makes its future results of operations
difficult to predict. The Company's operating results may fluctuate
significantly in the future as a result of a variety of factors such as the
introduction of new products or services by the Company or its competitors, 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 timing in the deployment of the Company's products by customers,
technical difficulties with respect to product development or the use of
products developed by the Company and general economic conditions.

RESULTS OF OPERATIONS

YEAR ENDED DECEMBER 31, 1997 AS COMPARED TO THE YEAR ENDED DECEMBER 31,
1996 AND THE PERIOD FROM DECEMBER 8, 1995 (INCEPTION) TO DECEMBER 31, 1995
COMBINED WITH THE PREDECESSOR FOR THE PERIOD FROM MAY 15, 1995 (PREDECESSOR'S
INCEPTION) TO DECEMBER 18, 1995. UNLESS OTHERWISE INDICATED THE DISCUSSION OF
THE COMBINED AMOUNTS IS REFERRED TO AS "1995" HEREIN.

Net revenues for the year ended December 31, 1997 were $5.4 million as
compared to $867,000 for the year ended December 31, 1996. The Company had no
revenues during 1995.

During 1997, the Company's sales mix shifted towards the sale of
gateway systems and IP telephony server products, representing 46% of net
revenues during 1997 as compared to 6% during 1996. Net revenues generated from
gateway systems and server software included the sale of the Company's software
based products as well as the sale of fully integrated "turn-key" systems, where
the Company integrates third party computer hardware and software components
with its gateway and server software. The increase in gateway system and server
software revenues is due to the commercial deployment and trial evaluations of
the Company's products and systems by service providers, including telephone
companies, cable companies and other common carriers and equipment suppliers.

Net revenues from client software represented 35% and 72% of net
revenues for the years ended December 31, 1997 and 1996, respectively. Net
revenues generated from client software were primarily due to a product license
and distribution agreement with Creative. Creative represented the Company's
largest

18
<PAGE>

customer during 1997 and 1996, accounting for 47% and 76% of net revenues,
respectively. The Company expects that revenues generated from Creative, as well
as client software, will decrease significantly in future periods. The Company
anticipates that its sales mix will shift predominately towards the sale of
gateway systems, IP telephony server products and call center systems, including
turn-key systems, in future periods.

Cost of revenues for the year ended December 31, 1997 was $931,000, or
17% of net revenues, as compared to $47,000, or 5% of net revenues, for the year
ended December 31, 1996. The increase in cost of revenues was primarily due to a
shift in the Company's sales mix towards the sale of fully integrated "turn-key"
gateway systems. The Company began selling fully integrated systems in the
fourth quarter of 1997 as a short-term means of expediting the distribution of
its technology, and anticipates that sales of fully integrated systems will
increase as a percentage of net revenues, to represent a significant portion of
the Company's sales mix in the near term and, as a result, cost of revenues will
also increase as a percentage of net revenues. However, the Company believes
that cost of revenues will decrease as a percentage of net revenues in the
longer term as the Company expects that system integration will be performed by
its partners and, as a result, the Company anticipates its sales mix will
primarily consist of software based solutions in the long term. Additionally,
should the Company elect to manufacture and sell certain specialized computer
hardware components that it is currently designing, cost of revenues would
increase as a percentage of net revenues. The Company had no cost of revenues
during 1995.

Research and development expenses for the year ended December 31, 1997
were $5.5 million as compared to $2.3 million for the year ended December 31,
1996. Research and development expenses during 1995 were $203,000. The increases
in research and development expenses were primarily the result of the expansion
of the Company's research and development staff. As a result, the Company
experienced an increase in costs related to compensation expense, as well as
computer hardware and software utilized in product development and greater
equipment depreciation expense. The Company also developed and introduced a new
line of gateway products on a new hardware platform during 1997 and, as a
result, incurred additional costs to facilitate the development and testing of
these products. All research and development costs have been expensed as
incurred. The Company intends to significantly increase research and development
expenses in future periods to perform product enhancements and new product
development to maintain a competitive advantage. In connection with the
acquisition of Internet Telephone Company, $557,000 of purchased research and
development was charged to expense in 1995. See Note 2 to the consolidated
financial statements.

Sales and marketing expenses for the year ended December 31, 1997 were
$2.9 million as compared to $722,000 for the year ended December 31, 1996. The
increase in sales and marketing expenses was primarily due to the expansion of
the Company's sales and marketing staff. During 1997, the Company opened two
branch sales offices and increased its promotional activities, primarily through
generating a greater presence at industry trade shows and conferences. The
Company intends to continue to intensify and expand its sales and marketing
efforts and, as a result, expects sales and marketing expenses to significantly
increase in future periods. The Company had no sales and marketing expenses
during 1995.

General and administrative expenses for the year ended December 31,
1997 were $1.6 million as compared to $837,000 for the year ended December 31,
1996. General and administrative expenses during 1995 were $63,000. The increase
in general and administrative expenses was due to the addition of personnel and
greater operating expenses as a result of the expansion of the Company's
corporate infrastructure. The Company expects general and administrative
expenses to increase in future periods as it continues to expand its corporate
infrastructure.

19
<PAGE>

Interest and other income for the years ended December 31, 1997 and
1996 was $753,000 and $172,000, respectively. The increase in interest income is
the result of interest earned on excess funds attributable to the net proceeds
from the IPO. The Company had no interest income during 1995.

Income taxes for the years ended December 31, 1997 and 1996 were
$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. The Company paid no income taxes during 1995.

LIQUIDITY AND CAPITAL RESOURCES

The Company currently does not have any available lines of credit. The
Company has financed its operations through sales of equity securities. Prior to
completion of the IPO in June 1997, the Company raised approximately $8.7
million, net of offering costs, from private sales of securities in a private
placement and to Motorola and Creative, two strategic partners. As of December
31, 1997, the Company had $4.7 million in cash and cash equivalents and $14.3
million in short-term investments. In January 1998, the Company sold 1,334,171
shares of Common Stock for $36.8 million, net of offering costs, in a private
transaction to Bay Networks, another strategic partner.

Net cash used in operating activities during the years ended December
31, 1997 and 1996 was $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 and sales and marketing efforts.

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, 1997 was $20.4 million. On June 3, 1997, the Company closed on the IPO of
its Common Stock. The Company offered and sold 2,400,000 shares of Common Stock
at an initial public offering price of $8.75 per share, raising proceeds, net of
offering costs, of approximately $17.9 million. Upon consummation of the IPO,
Motorola, Inc., a strategic partner of and investor in the Company, exercised a
previously granted warrant to purchase 452,855 shares of Common Stock for $2.5
million or $5.50 per share.

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 leases. The Company expects to significantly increase its capital
expenditures in future periods as a result of its anticipated growth, primarily
through the purchase of computer-related equipment for use in research and
development activities. The Company anticipates that, based on its present plans
and assumptions, the current cash balances will be sufficient to enable it to
maintain its current and planned operations for a period of at least the next 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 needed 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

In October 1997, the American Institute of Certified Public Accountants
("AICPA") issued statement of position ("SOP") 97-2, "Software Revenue
Recognition," which supersedes SOP 91-1. SOP 97-2 provides guidance as to when
revenue should be recognized and in what amounts for licensing, selling, leasing
or otherwise marketing computer software. SOP 97-2 is effective for transactions
entered into for annual periods beginning after December 15, 1997. The Company
will adopt SOP 97-2 in 1998 and is in the process of evaluating the impact, if
any, on the Company.

YEAR 2000 MATTERS

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
two separate areas, through the internal computer applications on which it
relies as well as the software which it develops and sells. NetSpeak is in
process of reviewing all significant third party applications which it utilizes
and obtaining documentation from the manufacturers which certify Year 2000
compliance. The Company also is in process of examining the architecture of its
products, as well as documentation on the third party components which are
integrated into the Company's software products, and believes that its products
are Year 2000 compliant. The Company is also developing a test plan, for both
internal applications and software which the Company develops, to validate the
results of its initial review. Should the Company find any items which are not
Year 2000 compliant in the course of its testing, the Company will take the
necessary actions to correct the matter. The Company expects that its testing
procedures and any required Year 2000 compliance activities will be completed by
December 31, 1998. The Company does not anticipate that Year 2000 compliance
activities will have a material effect on the Company's business, financial
position or results of operations. However, there can be no assurance that the
Company's systems and products are Year 2000 compliant until the successful
completion of its testing procedures. Additionally, there can be no assurance
that the systems of other companies on which the Company relies will be Year
2000 compliant which could result in a material adverse effect on the Company.

FORWARD LOOKING STATEMENTS

Except for the historical information contained herein, this "Item 7.

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, 1996 and
1997, and the related consolidated statements of operations, shareholders'
equity and cash flows of Internet Telephone Company (the "Predecessor") for the
period from May 15, 1995 (date of inception) to December 18, 1995, and of the
Company for the period December 8, 1995 (date of inception) to December 31, 1995
and for the years ended December 31, 1996 and 1997. 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, 1996 and 1997, and the results of operations and cash flows of the
Predecessor for the period from May 15, 1995 (date of inception) to December 18,
1995, and of the Company for the period December 8, 1995 (date of inception) to
December 31, 1995 and the years ended December 31, 1996 and 1997 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 (collectively, the "Company") develops, markets, licenses, and
supports a suite of intelligent software products and systems, 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 ("LANs" and "WANs", respectively).

The markets for the Company's products and systems have only recently
begun to develop and are rapidly evolving. Additionally, the Company's products
and systems are based on emerging technologies. As is typical in the case of new
and rapidly evolving industries, demand and market acceptance for recently
introduced technology products 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. The Company's prospects must be considered in light of
the risks, expenses and difficulties frequently encountered by companies in the
early stage of development, particularly companies in new and rapidly evolving
markets. As of December 31, 1997, the Company had an accumulated deficit of $8.6
million. Additionally, the Company's operating results 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 the volume of revenues
generated to the Company's strategic partners from sales of products and systems
incorporating the Company's technology or products, the emergence of new
competitors in the marketplace, the mix of distribution channels used by the
Company, the timing of new product announcements and release by the Company and
its competitors, and general economic conditions. However, the Company believes
that adequate capital resources are available to fund the Company's operations
for a period of at least twelve months.

NetSpeak was incorporated on December 8, 1995 under the name "Comnet
Corporation" and assumed its present name on December 18, 1995. For accounting
purposes, the Company emerged from the development stage during 1996.

Effective December 18, 1995, NetSpeak acquired the Internet Telephone
Company ("ITC"). ITC was incorporated for the purpose of developing telephony
communication software for use on the Internet and LANs and WANs. The
accompanying financial statements identified as for the Predecessor are for ITC
for the period from May 15, 1995 (inception) to the date of acquisition. The
accompanying financial statements identified as for the Successor are for the
Company, including ITC on a consolidated basis, as of December 31, 1996 and 1997
and for the period from December 8, 1995 (inception) to December 31, 1995 and
for the years ended December 31, 1996 and 1997. See Note 2.

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

ACCOUNTING 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.

28
<PAGE>

NET LOSS PER SHARE - The Company adopted Statement of Financial
Accounting Standards ("SFAS") No. 128 in the fourth quarter of 1997. SFAS No.
128 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. Pursuant to the requirements of Staff Accounting Bulletin ("SAB")
No. 98 of the Securities and Exchange Commission, issued in February 1998,
common equivalent shares which have an anti-dilutive effect on net loss per
share are no longer included in computing net loss per share for the period that
includes the initial public offering. All prior-period loss per share data has
been restated in accordance with SFAS No. 128 and SAB No. 98.

REVENUE RECOGNITION - The Company generates revenues from products,
licenses and fees for services. License revenue includes a combination of fees
for initial and annual license fees. Service revenues are derived from fees for
customer maintenance and support and engineering.

Product and license revenues are generally recognized upon product
shipment or delivery of permanent authorization codes. License fees which cover
a specified time period are amortized ratably over the term of the license
agreement.

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, except when customer acceptance is required, then
revenues are recognized when customer acceptance has been received.

Costs related to insignificant obligations, primarily telephone
support, are accrued upon product shipment.

Advance payments of products, licenses and services are reported as
unearned revenue until all conditions for revenue recognition are met.

RESEARCH AND DEVELOPMENT - Research and development expenditures are
charged to operations as incurred. SFAS No. 86, "Accounting for the Costs of
Computer Software to be Sold, Leased or Otherwise Marketed," requires
capitalization of certain software development costs once technological
feasibility has been established.

Based on the Company's product development process, technological
feasibility is established upon completion of a working model. Costs incurred by
the Company between 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.

FINANCIAL INSTRUMENTS - Cash and cash equivalents include cash and
short-term investments purchased with a maturity of three months or less.
Short-term investments generally mature between three months and two years from
the purchase date. All short-term investments are classified as available for
sale and are recorded at fair value. Unrealized gains and losses are to be
reported in shareholders equity. There were no significant differences between
cost and fair value for all classifications of short-term investments, nor were
there significant unrealized holding gains.

FAIR VALUE OF FINANCIAL INSTRUMENTS - SFAS No. 107, "Disclosure about
Fair Value of Financial Instruments," require 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

29
<PAGE>

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. There were no significant differences as of
December 31, 1996 and 1997 in the carrying value and fair value.

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 3 to 5 years.

INCOME TAXES - Income taxes are provided based on the treatment
prescribed by SFAS No. 109, "Accounting for Income Taxes". SFAS No. 109 requires
accounting for income taxes based on the 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.

RECENT ACCOUNTING PRONOUNCEMENT - In October 1997, the American
Institute of Certified Public Accountants ("AICPA") issued statement of position
("SOP") 97-2, "Software Revenue Recognition," which supersedes SOP 91-1. SOP
97-2 provides guidance as to when revenue should be recognized and in what
amounts for licensing, selling, leasing or otherwise marketing computer
software. SOP 97-2 is effective for transactions entered into for annual periods
beginning after December 15, 1997. The Company will adopt SOP 97-2 in 1998 and
is in the process of evaluating the impact, if any, on the Company.

2. ACQUISITION OF ITC

Effective December 18, 1995, the Company acquired ITC by issuing
2,500,000 shares of the Company's common stock, valued at $500,000, in exchange
for all of the outstanding shares of ITC. The acquisition was accounted for as a
purchase. The purchase price was allocated to the assets acquired, including
purchased research and development in process, and liabilities assumed based
upon their fair value on the date of acquisition. ITC's only activities from
inception to the date of acquisition consisted of research and development of
telephony communication software, and as such operating activities did not
commence. As of the date of the acquisition, technological feasibility of the
telephony communication software in process of development had not been
established and there was no alternative use; accordingly, the portion of the
purchase price allocated to purchased research and development was immediately
expensed in accordance with general accepted accounting principles. Pro forma
information for 1995 giving effect to the acquisition is not presented because
such information would not be significantly different from that in the
historical statements of operations. The following summarizes the acquisition
(in thousands):

Equipment acquired.................................... $ 25

3. SHAREHOLDERS' EQUITY.................................

The initial capitalization of the Company consisted of the issuance of
2,500,000 shares of common stock for $500,000.

ITC's capitalization since inception consisted of the issuance of 1,000
shares of common stock for $1,000 cash and additional capital contributions of
$128,000.

30
<PAGE>

During the period from December 8, 1995 to December 14, 1995, the
Company issued 450,000 shares of common stock for $90,000.

In the first quarter of 1996 the Company sold 1,204,000 million 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 for $2.50 per share to a consulting firm, which
assisted the Company with its private placement. The fair value of this option,
$271,000, was recorded as a cost of the offering. The option expires in January
2003.

In June 1996, the Company issued 207,679 shares of common stock to
Creative Technology Ltd. ("Creative") at a price of $5.05 per share raising an
aggregate of $944,000, net of offering costs. The Company also issued Creative a
21 month warrant to purchase up to an additional 207,679 shares of common stock
at a price of $5.05 per share, which warrant is only exercisable if Creative
distributes, during a specified period, a predetermined quantity of the
Company's Internet telephone client software product licensed to Creative.
During 1997, the Company determined that the product distribution requirements
were likely to be met and recorded as an expense the fair value, $66,000, of the
warrant. The Company derived 44% and 47% of its net revenues from Creative for
the years ended December 31, 1996 and 1997, respectively.

In August 1996, the Company issued 769,853 shares of common stock at a
price of $5.50 per share and a warrant to purchase up to an additional 452,855
shares of common stock at a price of $5.50 per share for a six year period
expiring in August 2002 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 offering costs, of $17,943,000. Upon consummation of the offering,
Motorola, Inc., exercised the previously granted warrant to purchase 452,855
shares of Common Stock for $2,491,000.

In January 1998, the Company entered into a joint development and
equity 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.

The Company has authorized 1,000,000 shares of preferred stock, $.01
par value. No shares of preferred stock have been issued.

The Company applies Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees", and related interpretations
in measuring stock based compensation, including options. Accordingly, no
compensation expense has been recognized for options granted under the
Plan. Had compensation expense been determined based upon the fair value
at the grant date for awards under the Plan consistent with SFAS No. 123,
"Accounting for Stock-Based Compensation," the Company's net loss and net
loss per share, on a pro forma basis, would have been:

Proforma net loss................. $ (642) $ (3,123) $ (5,599)
Proforma net loss per share....... $ (0.15) $ (0.44) $ (0.60)
</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 and 1997 was $0.83 and $4.69, respectively. Employee stock
options granted in 1995 had no fair value. The following assumptions were
used in calculating the fair values: dividend yield 0%, expected
volatility 60%, risk-free interest rates ranging between 5.39% and 6.77%,
and an expected life of 5 years. An expected volatility of 0% was used
prior to the Company's IPO.

7. COMMITMENTS AND CONTINGENCIES

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, 1997 are as follows (in
thousands):

YEAR ENDING DECEMBER 31,

1998.............. $ 282
1999.............. 289
2000 ............. 162
2001.............. 7
---------------
$ 740
===============

Rent expense for the periods ended December 31, 1995, 1996 and 1997
was $1,000, $67,000 and $168,000, 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 and
1997 were $0 and $19,000, respectively. The administrative costs of the
plan are paid by the Company.

The Company has entered into employment agreements with six officers
with salaries aggregating $1,140,000 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.

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.

Elk Industries has asserted, in a letter to the Company, just prior
to the November 1996 expiration of U.S. Patent No. 4,128,773, owned by Elk
Industries, that the Company's WebPhone client software product infringed
the now expired patent. The Company sought advice of counsel relating to
the

34
<PAGE>

infringement allegations, which Elk Industries has asserted against other
software concerns, and believes, based upon an opinion of counsel, the Company's
WebPhone client software product does not infringe the asserted patent.
Accordingly, the Company believes that this matter will not have a material
effect on its financial position and results of operations.

In May 1997, the Company received a letter from e-Net, Inc. ("e-Net")
alleging that the Company's WebPhone product infringes U.S. Patent No.
5,526,353 owned by e-Net. Although, there can be no assurance of the
outcome of this uncertainty, following an analysis of the subject patent
and the WebPhone product, management believes the allegations are without
merit and that any potential liability related to e-Net's allegations will
not have a material effect on the Company's financial position and 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, enhance 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 to predict the impact, if any, that future legislation, legal
decisions or regulations may have on its business, financial condition or
results of operations.

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 two separate areas, through the internal
computer applications on which it relies as well as the software which it
develops and sells. NetSpeak is in process of reviewing all significant
third party applications which it utilizes and obtaining documentation from
the manufacturers which certify Year 2000 compliance. The Company also is
in process of examining the architecture of its products, as well as
documentation on the third party components which are integrated into the
Company's software products, and believes that its products are Year 2000
compliant. The Company is also developing a test plan, for both internal
applications and software which the Company develops, to validate the
results of its initial review. Should the Company find any items which are
not Year 2000 compliant in the course of its testing, the Company will
take the necessary actions to correct the matter. The Company expects that
its testing procedures and any required Year 2000 compliance activities
will be completed by December 31, 1998. The Company does not anticipate
that Year 2000 compliance activities will have a material effect on the
Company's business, financial position or results of operations. However,
there can be no assurance that the Company's systems and products are Year
2000 compliant until the successful completion of its testing procedures.
Additionally, there can be no assurance that the systems of other
companies on which the Company relies will be Year 2000 compliant which
could result in a material adverse effect on the Company. (unaudited)

8. INCOME TAXES

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

35
<PAGE>
DECEMBER 31,
-----------------------
1996 1997
-------- ---------
(in thousands)
Current - Foreign............ $ 225 $ 60
Deferred - Foreign........... (182) 149
-------- ---------
$ 43 209
======== =========

Income taxes for the year ended December 31, 1996 and 1997 were
attributable to income taxes paid to the Singapore government related to
license fees received pursuant to an agreement with Creative. The Company
did not pay income taxes during 1995.

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, 1996 and 1997, the Company had deferred tax assets as follows:

DECEMBER 31,
---------------------------
1996 1997
----------- ------------
(in thousands)
Deferred tax assets:

Unearned revenue - foreign................ $ 182 $ 33
Net operating loss carryforwards.......... 1,291 3,097
Valuation allowance....................... (1,291) (3,097)
----------- ------------
Net deferred tax asset................ $ 182 $ 33
=========== ============

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, 1996 and 1997, the Company had approximately
$3,254,000 and $7,829,000, respectively, of federal and state net
operating loss carryforwards 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 year period. As
of December 31, 1997, 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% as follows:

36
<PAGE>

DECEMBER 31,
------------------------
1996 1997
--------- --------
Statutory rate applied to...............
earnings before income taxes.......... 34.0% 34.0%

Foreign taxes........................... (1.5) (4.3)
Valuation allowance..................... (37.6) (37.6)
