         THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY THE MORE DETAILED
INFORMATION AND CONSOLIDATED FINANCIAL STATEMENTS, INCLUDING THE NOTES THERETO,
APPEARING ELSEWHERE IN THIS PROSPECTUS. INVESTORS SHOULD CAREFULLY CONSIDER THE
INFORMATION SET FORTH UNDER THE HEADING "RISK FACTORS." EXCEPT AS OTHERWISE
INDICATED, ALL INFORMATION IN THIS PROSPECTUS (I) ASSUMES NO EXERCISE OF THE
OVER-ALLOTMENT OPTION; (II) ASSUMES NO EXERCISE OF THE WARRANTS TO BE ISSUED BY
THE COMPANY TO THE REPRESENTATIVE TO PURCHASE UP TO 200,000 SHARES OF COMMON

                                   THE COMPANY

         NetSpeak develops, markets, licenses, and supports a suite of
intelligent software modules 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 Company believes that its technology is strategically
positioned to capitalize on the rudimentary shift in corporate
telecommunications philosophy as businesses seek to expand the functionality of
their communication systems as well as optimize their use of packetized data
networks, thereby eventually eliminating the redundancy inherent in maintaining
a traditional voice network simultaneously with a packetized data network.
Netspeak is currently marketing a user-friendly core communications technology
which enables, in a cost-effective manner, corporations and other users to
enhance the role of their packetized data networks to support concurrent voice,
video and data transmission. NetSpeak believes that as potential users become
increasingly educated as to the benefits of integrating the two networks,
significant revenue opportunities for the Company will be generated.

         The Company's software uses its proprietary intelligent virtual circuit
switching technology to provide gateways between packetized data networks and
traditional voice transmission networks. The technology also allows users to
integrate into packetized data networks a variety of features and functions
commonly found in traditional voice transmission networks, including automatic
call distribution ("ACD"), multi-point conferencing, interactive voice response
services, messaging services, and least cost routing, as well as to expand
functionality by offering additional features such as concurrent voice and data
transmission and video conferencing. The Company's virtual circuit switching
technology provides intelligent call routing to enable users to transparently
communicate with each other on a point-to-point basis. The Company believes that
its products and systems are designed to allow customers to integrate NetSpeak's
technology into their existing network infrastructures without the need for
significant upgrading, and can ultimately provide a complete software-based
solution for the delivery of concurrent real-time interactive voice, video and
data communications over packetized data networks.

         In order to facilitate and accelerate the acceptance of NetSpeak's
technology as well as enhance the marketing and distribution of its products and
systems, the Company has established a number of strategic alliances with
various telecommunications and computer industry leaders. Under 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, as well as insights into market
trends and product development.

         In August 1996, the Company established a strategic alliance with
Motorola, Inc. ("Motorola"), pursuant to which Motorola made a minority
investment in the Company and the Company granted Motorola a right of first
negotiation on licenses of the Company's technology as it applies to the
cellular and cable communications industries. Motorola is also conducting a
number of end-user test trials of systems that combine the Company's technology,
products and systems with those of Motorola.

         Beginning in June 1996, the Company entered into a strategic alliance
with Creative Technology, Ltd. ("Creative"), a world leader in the manufacture
and distribution of audio cards and multimedia computer peripherals. Pursuant to
such alliance, Creative made a minority investment in the Company. NetSpeak
granted Creative a world-wide license to market, distribute and bundle
NetSpeak's WebPhone client (or end-user) software under the Creative brand name
in the retail distribution channel and the Company and Creative are jointly
developing various other Internet-related software applications which use both
the Company's and Creative's proprietary technologies, in such areas as radio
broadcast.

         In August 1996, the Company established a strategic alliance with the
Switching Systems Division of Rockwell International Corporation ("Rockwell"),
an industry leader in medium to high end ACD systems. As part of this alliance,
the Company's gateway products and ACD systems are being integrated into
Rockwell's ACD systems. Beginning in November 1996, the Company entered into a
strategic alliance with Infonet Services Corporation ("Infonet"), one of the
largest commercial data network carriers in the world. Pursuant to such
alliance, the Company will integrate its technology with Infonet's existing
global data network, to enhance concurrent voice and data transmission over the
network. The Company intends to seek to establish additional strategic
alliances.

         In addition to marketing its technology, products and systems with its
strategic partners, NetSpeak has begun to market its products directly to
end-users, including telephone companies, cable companies, and other common
carriers, large business enterprises, ACD manufacturers and other equipment
manufacturers ("OEMs"), governmental and educational entities, as well as to
distributors, such as systems integrators ("SIs") and value added resellers
("VARs"). To date, such marketing efforts primarily have been limited to direct
contacts with a number of these customers. In addition, NetSpeak is marketing
its WebPhone client software products over the Internet, by advertising in
computer periodicals and through distribution agreements with over 700 Internet
service providers ("ISPs") worldwide. The Company is currently developing an
in-house marketing and sales infrastructure.

(1)    NetSpeak acquired ITC by issuing 2,500,000 shares of common stock, valued
       at $500,000, in exchange for all of the outstanding shares of ITC. The
       acquisition was accounted for as a purchase, and 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. The financial information identified
       herein as for the Predecessor is for ITC for the period May 15, 1995
       (inception) to December 18, 1995, the date of its acquisition by
       NetSpeak. The financial information identified herein as for the
       Successor is for NetSpeak (including ITC on a consolidated basis from the
       date of acquisition) as of December 31, 1995 and 1996 and for the period
       from December 8, 1995 (inception) to December 31, 1995 and for the year
       ended December 31, 1996.

       explanation of the determination of the number of shares and share
       equivalents used in computing the per share amounts. Does not give effect

       Advisor's Warrants to purchase 200,000 shares of Common Stock,
       exercisable at 120% of the public offering price per share; (iii)
       outstanding warrants to purchase 660,534 shares of Common Stock
       exercisable at prices ranging from $5.05 to $5.50 per share; and (iv)
       stock options to purchase 1,710,000 shares of Common Stock granted under
       the 1995 Plan prior to February 1, 1996, which are not included because
       such options were issued prior to the 12 months immediately preceding the
       Offering and the effect on net loss per share would be anti-dilutive.

                                  RISK FACTORS

         AN INVESTMENT IN THE SHARES OF COMMON STOCK OFFERED HEREBY IS
SPECULATIVE IN NATURE AND INVOLVES A HIGH DEGREE OF RISK. IN ADDITION TO THE
OTHER INFORMATION CONTAINED IN THIS PROSPECTUS, THE FOLLOWING FACTORS SHOULD BE
CONSIDERED CAREFULLY IN EVALUATING THE COMPANY AND ITS BUSINESS BEFORE
PURCHASING THE SHARES OF COMMON STOCK OFFERED HEREBY. THIS PROSPECTUS CONTAINS,
IN ADDITION TO HISTORICAL INFORMATION, FORWARD-LOOKING STATEMENTS THAT INVOLVE
RISKS AND UNCERTAINTIES. THE COMPANY'S ACTUAL RESULTS COULD DIFFER MATERIALLY.
FACTORS THAT COULD CAUSE OR CONTRIBUTE TO SUCH DIFFERENCES INCLUDE, BUT ARE NOT
LIMITED TO, THOSE DISCUSSED BELOW AS WELL AS THOSE DISCUSSED ELSEWHERE IN THIS
PROSPECTUS.

         LIMITED OPERATING HISTORY; ACCUMULATED DEFICIT; EARLY STAGE OF
DEVELOPMENT. The Company commenced initial research and development efforts in
May 1995, released its initial products in February 1996 and has only recently
emerged from the development stage. Accordingly, 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, 1996, the Company had an accumulated deficit of
$3,508,187. The Company's prospects must be considered in light of the risks,
expenses and difficulties frequently encountered by companies in an early stage
of development, particularly companies in new and rapidly evolving industries.
To address these risks and achieve profitability and increased sales levels, the
Company must, among other things, establish and increase market acceptance of
its technology, products and systems, respond effectively to competitive
pressures, introduce on a timely basis products and systems incorporating its
technology and enhancements to its product applications and successfully market
and support its products and systems. There can be no assurance that the Company
will achieve or sustain significant sales or profitability in the future. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."

         UNCERTAINTY OF PRODUCT ACCEPTANCE IN DEVELOPING MARKETS; NEW PRODUCT
DEVELOPMENT RISKS. The markets for the Company's technology, products and
systems have only recently begun to develop and are rapidly evolving. In
addition, the Company's products and systems are new and based on emerging
technologies. As is typical in the case of new and rapidly evolving industries,
demand and market acceptance for recently introduced technology and products are
subject to a high level of uncertainty. Broad acceptance of the Company's
technology, products and systems is critical to the Company's success and
ability to generate revenues. Acceptance of the Company's technology, products
and systems will be highly dependent on the functionality and performance of the
products and systems and particularly on the success of the initial
implementation of its products and systems. There can be no assurance that the
Company will be successful in obtaining market acceptance of its technology,
products and systems. In addition, the Company's products and systems must be
adapted in certain instances to meet the specific requirements of the customer
hardware or software in which it is to be integrated. The adaptation process can
be time consuming and costly to both the Company and its customers and the
acceptance of the product or system may depend, to a substantial extent, on the
success of the adaptation.

                                       -9-


<PAGE>

         Furthermore, products and systems offered by the Company may contain
undetected errors or defects when first introduced or as new versions are
released. Introduction by the Company of products and systems with reliability,
quality or compatibility problems could result in reduced revenues,
uncollectible accounts receivable, delays in collecting accounts receivable and
additional costs. There can be no assurance that, despite testing by the Company
or by its customers, errors will not be found in the Company's products and
systems after commencement of commercial deployment, resulting in product
redevelopment costs and loss of, or delay in, market acceptance. In addition,
there can be no assurance that the Company will not experience significant
product returns in the future. Any such event could have a material adverse
effect on the Company's business, financial condition and results of operations.
See "Business-Products" and "-Research and Development."

         NEED FOR CONTINUOUS PRODUCT DEVELOPMENT; RISKS OF RAPID TECHNOLOGICAL
CHANGE. The markets for the Company's products and systems are characterized by
rapidly changing technology. The introduction of products and systems which
offer applications incorporating new technologies could render the Company's
products obsolete and unmarketable and could exert price pressures on existing
products. Further, the markets for the Company's products and systems, including
the market for voice transmission over packetized data networks, are
characterized by evolving industry standards and specifications. As new
standards or specifications are adopted, the Company may be required to devote
substantial time and expense in order to adapt its technology, products and
systems. The Company's ability to anticipate changes in technology and industry
standards and successfully develop and introduce enhanced product applications
as well as new applications, in each case in a cost effective and timely manner,
will be a critical factor in the Company's ability to grow and be competitive.
There can be no assurance that the Company will successfully develop enhanced or
new product applications, that any enhanced or new product application will
achieve market acceptance, that the Company will be able to adapt its products
or systems to comply with new standards or specifications, or that the
introduction of new products or technologies by others will not render the
Company's technology, products and systems obsolete. See "Business-Products and
Systems" and "-Research and Development."

         LIMITED MARKETING EFFORTS; RELIANCE ON STRATEGIC PARTNERS. To date, the
Company's marketing efforts primarily have been limited to establishing
strategic alliances and, to a lesser extent, commencement of in-house marketing
efforts to end-users and distributors. The Company believes that it will be
dependent in the near term upon its strategic alliances, in particular those
with Rockwell and Creative, to generate revenues from the sales of products and
systems incorporating the Company's technology or products. Creative accounted
for approximately 44% of the Company's net revenues during the year ended
December 31, 1996. There can be no assurance that Rockwell or Creative will
actively distribute the Company's technology, products and systems or that, if
they do so, that their efforts will be successful or generate significant
revenues for the Company. Although the Company is currently developing an
in-house marketing and sales infrastructure to focus on direct sales to
potential end-users and distributors, there can be no assurance that the Company
will have the necessary resources to do so, or that any such efforts undertaken
will be successful. See "Business-Strategic Alliances" and "-Marketing and
Sales."

                                      -10-


<PAGE>

         HIGHLY COMPETITIVE INDUSTRY. The Company is unaware of any other
company which competes directly with the entire spectrum of products and systems
it offers. The Company does, however, face competition for each of the
individual products and systems. The Company competes with companies such as
Vienna Systems Corporation ("Vienna Systems"), Lucent Technologies, Inc.
("Lucent") and VocalTec, Ltd. ("VocalTec") with respect to its gateway products.
Principal competitors for NetSpeak's software-based business systems include
companies such as Lucent. In the market for client software products, the
Company competes with VocalTec, Microsoft Corporation ("Microsoft") and Intel
Corporation ("Intel"), among others. The Company expects competition to persist,
intensify and increase in the future. 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. In addition, the Company competes with
manufacturers of hardware-based business systems. Certain of these competitors
may be existing or potential strategic partners. There can be no assurance that
the Company will be able to compete effectively against its competitors. See
"Business-Competition."

         DEPENDENCE ON KEY PERSONNEL. The Company's performance is substantially
dependent on the performance of its executive officers, particularly Stephen R.
Cohen, the Company's Chairman of the Board and Chief Executive Officer; Robert
Kennedy, President and Chief Operating Officer and Shane D. Mattaway, Executive
Vice President and Chief Technical Officer. Given the Company's early stage of
development, it is dependent on its ability to retain and motivate high quality
personnel, especially management and skilled development teams. The loss of the
services of any of its executive officers or other key employees could have a
material adverse effect on the Company's business, financial condition and
results of operations. The Company's future success also depends on its
continuing ability to attract and retain additional highly qualified technical
personnel. Competition for qualified personnel is intense and there can be no
assurance that the Company will be able to attract, assimilate or retain
qualified personnel in the future. The inability to attract and retain the
necessary technical and other personnel could have a material adverse effect
upon the Company's business, operating results and financial condition. See
"Business-Research and Product Development" and "-Employees" and "Management."

         UNCERTAINTY REGARDING PATENTS AND PROPRIETARY RIGHTS. The Company's
success will depend in part on its ability to obtain patent protection for its
products, preserve its trade secrets and operate without infringing upon the
proprietary rights of other parties. There can be no assurance that patent
applications to which the Company holds rights will result in the issuance of
patents, or that any issued patents will provide commercially significant
protection to the Company's technology. In addition, there can be no assurance
that others will not independently develop substantially equivalent proprietary
information not covered by patents to which the Company owns rights or obtain
access to the Company's know-how, or that others will not claim to have or will
not be issued patents which may prevent the sale of one or more of the Company's
products. In particular, Elk Industries, Inc. ("Elk Industries") has asserted in
a letter to NetSpeak just prior to the expiration of U.S. Patent No. 4,124,773
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 infringement allegations, which Elk Industries has asserted

                                      -11-


<PAGE>

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.

         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 sale and possibly alter the
design of the products. There can be no assurance that any licenses required
under any other 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.

         The software market has traditionally experienced widespread
unauthorized reproduction of products in violation of manufacturers'
intellectual property rights. Such activity is difficult to detect and legal
proceedings to enforce manufacturers' intellectual property rights are often
burdensome and involve a high degree of uncertainty and costs. The Company's
success is also dependent upon unpatented trade secrets which are difficult to
protect. 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 the Company their
ideas, developments, discoveries and inventions. There can be no assurance that
these agreements will provide adequate protection for the Company's trade
secrets, know-how, or other proprietary information in the event of any
unauthorized use or disclosures. See "Business-Patents and Proprietary Rights."

         RISKS OF INTERNET DISTRIBUTION. The Company distributes certain of its
client software products through, among other channels, the Internet.
Distributing the Company's products through the Internet makes the Company's
software products more susceptible to unauthorized copying and use than
distribution through conventional means. The Company has allowed, and currently
intends to continue to allow, potential customers to electronically download
from the Internet basic versions of its software for free to evaluate the
Company's products and subsequently order enhanced and other existing or future
products. There can be no assurance that, upon receiving orders for its enhanced
products, the Company will be able to collect payment from users that retain a
copy of the Company's enhanced and other existing or future products.

         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 and systems 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 concerning the Internet may have on its business,
financial condition or results of operations.

                                      -12-


<PAGE>

         In March 1996, the America's Carriers Telecommunication Association
(the "ACTA"), a group of telecommunications common carriers, filed a petition
(the "ACTA Petition") with the Federal Communications Commission (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. The FCC has thus far not granted relief sought under the ACTA
Petition, however, any action taken 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.
See "Business-Government Regulation."

         ABILITY TO MANAGE GROWTH. The Company has been rapidly expanding and
expects to continue to expand its management, research and development, testing,
quality control, marketing, sales and customer service and support operations,
as well as its financial and accounting controls, all of which has placed and is
expected to continue to place a significant strain on the Company. The Company
has grown from a development staff of six persons at December 31, 1995 to 56
employees at December 31, 1996. Failure to integrate new personnel on a timely
basis could have an adverse effect on the Company's operations. Furthermore, the
expenses associated with expanding the Company's management team and hiring new
employees have been and are being incurred prior to the generation of any
significant revenues. If the Company's management is unable to manage growth
effectively, the quality of the Company's products, its ability to retain key
personnel and its business, financial condition and results of operations could
be materially adversely affected.

         POTENTIAL FLUCTUATIONS IN OPERATING RESULTS. Significant annual and
quarterly fluctuations in the Company's results of operations may be caused by,
among other factors, the volume of revenues generated by the Company's strategic
partners from sales of products and systems incorporating the Company's
technology or products, the mix of distribution channels used by the Company,
the timing of new product announcements and releases by the Company and its
competitors and general economic conditions. There can be no assurance that the
level of revenues and profits, if any, achieved by the Company in any particular
fiscal period will not be significantly lower than in other, including
comparable, fiscal periods. The Company's expense levels are based, in part, on
its expectations as to future revenues. As a result, if future revenues are
below expectations, net income or loss may be disproportionately affected by a
reduction in revenues as any corresponding reduction in expenses may not be
proportionate to the reduction in revenues. As a result, the Company believes
that period-to-period comparisons of its results of operations may not
necessarily be meaningful and should not be relied upon as

                                      -13-

indications of future performance. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."

         POSSIBLE NEED FOR ADDITIONAL CAPITAL. The Company anticipates that,
based on its present plans and assumptions, the net proceeds of this Offering,
when combined with the Company's existing capital resources and anticipated cash
flow from operations, will be sufficient to enable it to maintain its current
and planned operations for a period of at least 12 months after consummation of
this Offering. 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 financings, or from strategic
alliances, may not be available when needed or may not be available on terms
acceptable to the Company, if at all. Additional financings may result in
dilution to existing shareholders. 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. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources."

         CONCENTRATION OF COMMON STOCK OWNERSHIP. Upon completion of this
Offering, the directors and executive officers of the Company and Motorola will
beneficially own approximately 46.6% and 12.0% of the Common Stock, respectively
(assuming the exercise of stock options and warrants held by such parties).
There are no agreements between management and Motorola with respect to voting
their respective shares of Common Stock. However, both management and Motorola
will have the ability to influence significantly the Company's affairs and
operations following completion of this Offering and, voting together, could
elect the Board of Directors and otherwise control the Company. See "Principal
Shareholders."

         DILUTION. Purchasers of shares of Common Stock in the Offering will
experience immediate and substantial dilution in net tangible book value per
share from the initial public offering price. Such dilution at December 31, 1996
would have been equal to $6.77 per share (or 75%) at an assumed initial public
offering price of $9.00 per share.

         LACK OF PRIOR PUBLIC MARKET AND POSSIBLE VOLATILITY OF STOCK PRICE.
Prior to this Offering, there has been no public market for the Common Stock,
and there can be no assurance that an active trading market will develop or be
sustained. The initial public offering price for the Common Stock to be sold in
this Offering will be arbitrarily determined by negotiation between the Company
and the Representative, and does not necessarily bear any relationship to the
Company's asset value, net worth or other established criteria of value, and
should not be considered indicative of the actual value of the Common Stock and
may bear no relationship to the price at which the Common Stock will trade after
completion of this Offering. The market price of the Company's Common Stock is
likely to be highly volatile and could be subject to wide fluctuations in
response to quarterly variations in operating results, losses of significant
customers, announcements of technological innovations or new products by the
Company and its competitors, changes in financial estimates by securities
analysts, or other events or factors, including the risk factors described
herein. In addition, the stock market has experienced significant price and
volume fluctuations that have particularly affected the market prices of equity
securities of many high technology companies and that often have been unrelated
to the operating

                                      -14-


<PAGE>

performance of such companies. In the past, following periods of volatility in
the market price of a company's securities, securities class action litigation
has often been instituted against such a company. Such litigation could result
in substantial costs and a diversion of management's attention and resources,
which would have a material adverse effect on the Company's business, operating
results and financial condition. See "Underwriting."

         SHARES ELIGIBLE FOR FUTURE SALE. Upon completion of this Offering, the
Company will have 9,698,532 shares of Common Stock outstanding. Of these shares,
the 2,000,000 shares of Common Stock sold in this Offering will be freely
tradeable without restriction under the Securities Act of 1933, as amended (the
"Securities Act"), except any such shares which may be acquired by an
"affiliate" of the Company. The holders of the currently outstanding 7,698,532
shares of Common Stock have agreed not to offer, sell or otherwise dispose of
such shares for nine months after the date of this Prospectus without the prior
written consent of the Representative. After this period, 5,428,000 of the
shares subject to this restriction will be eligible for sale in the public
market pursuant to Rule 144 under the Securities Act, subject to the volume
limitations and other restrictions contained in Rule 144. The remaining
2,270,532 of such shares will become eligible for sale subject to the
restrictions of Rule 144 at varying times from January 1998 to January 1999.

         As of the date of this Prospectus, options to purchase 2,246,000 shares
of common stock and warrants to purchase 660,534 shares of Common Stock are
issued and outstanding. In addition, the Company has granted to Motorola and
Creative certain demand and piggy-back registration rights under the Securities
Act with respect to the shares of Common Stock beneficially owned by them.
Future sales of the shares of Common Stock held by existing shareholders, or the
perception that such sales may occur, could have an adverse effect on the price
of the Common Stock. See "Certain Transactions" and "Shares Eligible for Future
Sale."

         ANTI-TAKEOVER PROVISIONS. The Company's Board of Directors has the
authority to issue up to 1,000,000 shares of "blank-check" preferred stock
("Preferred Stock"). Accordingly, shares of the Company's Preferred Stock may be
issued in the future without shareholder approval and upon such terms and
conditions, and having such rights, privileges and preferences as the Board of
Directors may determine. Such rights, privileges and preferences could include
preferential voting rights, dividend rights in excess of those provided to
holders of Common Stock, and conversion rights, redemption privileges or
liquidation preferences not available to holders of Common Stock. The rights of
holders of Common Stock will be subject to, and may be adversely affected by,
the rights of holders of any Preferred Stock that may be issued in the future.
Although the Company has no present intention to issue shares of Preferred
Stock, any issuance of Preferred Stock, while potentially providing desirable
flexibility in connection with possible acquisitions and other corporate
purposes, could have the effect of making it more difficult for a third party to
acquire a majority of the outstanding voting stock of the Company.

         In addition, Florida has enacted legislation that may deter or
frustrate takeovers of Florida corporations. The Florida Control Share Act
generally provides that shares acquired in a "control share acquisition" will
not possess any voting rights unless such voting rights are approved by a
majority of the corporation's disinterested shareholders. A "control share
acquisition" is an

                                      -15-


<PAGE>

acquisition, directly or indirectly, by any person of ownership of, or the power
to direct the exercise of voting power with respect to, issued and outstanding
"control shares" of a publicly held Florida corporation. "Control shares" are
shares, which, except for the Florida Control Share Act, would have voting power
that, when added to all other shares owned by a person or in respect to which
such person may exercise or direct the exercise of voting power, would entitle
such person, immediately after acquisition of such shares, directly or
indirectly, alone or as a part of a group, to exercise or direct the exercise of
voting power in the election of directors within any of the following ranges:
(a) at least 20% but less than 33-1/3% of all voting power, (b) at least 33-1/3%
but less than a majority of all voting power; or (c) a majority or more of all
voting power. The Florida Affiliated Transactions Act generally requires
supermajority approval by disinterested shareholders of certain specified
transactions between a public corporation and holders of more than 10% of the
outstanding voting shares of the corporation (or their affiliates). See
"Description of Capital Stock."

         RISKS ASSOCIATED WITH FORWARD-LOOKING STATEMENTS INCLUDED IN THIS
PROSPECTUS. This Prospectus contains certain forward-looking statements
regarding the plans and objectives of management for future operations,
including plans and objectives relating to the development of the Company's
business. The forward-looking statements included herein are based on current
expectations that involve numerous risks and uncertainties. The Company's plans
and objectives are based on a successful execution of the Company's business
strategy and assumptions that the Company will be profitable, that the market
for packetized voice transmission will not change materially or adversely, and
that there will be no unanticipated material adverse change in the Company's
operations or business. Assumptions relating to the foregoing involve judgments
with respect to, among other things, future economic, competitive and market
conditions and future business decisions, all of which are difficult or
impossible to predict accurately and many of which are beyond the control of the
Company. Although the Company believes that its assumptions underlying the
forward-looking statements are reasonable, any of the assumptions could prove
inaccurate and, therefore, there can be no assurance that the forward-looking
statements included in this Prospectus will prove to be accurate. In light of
the significant uncertainties inherent in the forward-looking statements
included herein, the inclusion of such information should not be regarded as a
representation by the Company or any other person that the objectives and plans
of the Company will be achieved.

         NO DIVIDENDS. The Company has not paid any dividends on its Common
Stock and anticipates for the foreseeable future that all earnings, if any, will
be retained for the operation and expansion of the Company's business. See
"Dividend Policy."

                                 USE OF PROCEEDS

         The net proceeds to be received by the Company from the sale of
2,000,000 shares of Common Stock offered hereby at an assumed public offering
price of $9.00 per share are estimated to be approximately $15,990,000
($18,501,000 if the Underwriters' over-allotment option is exercised in full),
after deducting the underwriting discount, the non-accountable expense allowance
and other estimated expenses of the Offering payable by the Company.

                                      -16-


<PAGE>

         The Company anticipates that approximately $5,100,000 of the net
proceeds will be used for increased marketing and sales efforts, approximately
$6,800,000 will be used for additional research and development efforts and
approximately $2,000,000 for capital expenditures. The balance of the net
proceeds will be used for working capital and other general corporate purposes.
Pending such uses, the Company intends to invest the net proceeds of this
Offering in short-term, investment-grade, interest-bearing securities.

         The Company believes that the net proceeds of this Offering, together
with its existing capital resources and anticipated cash flow from operations,
will be sufficient to enable it to maintain its current and planned operations
for a period of at least 12 months after consummation of the Offering. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."

                                 DIVIDEND POLICY

         The Company has not paid 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.

                                    DILUTION

         As of December 31, 1996, the net tangible book value of the Company was
$5,678,903 or $0.74 per share. Net tangible book value represents the amount of
total assets, less any intangible assets and total liabilities. After giving
effect to the sale of the 2,000,000 shares of Common Stock offered hereby (at an
assumed initial public offering price of $9.00 per share, and after deducting
the underwriting discount, the non-accountable expense allowance and other
estimated expenses of this Offering), the pro forma net tangible book value as
of December 31, 1996 would have been $21,668,903 or $2.23 per share. This
represents an immediate increase in net tangible book value of $1.49 per share
to existing shareholders and an immediate dilution of $6.77 per share to
investors in the Offering. The following table illustrates this per share
dilution:

Assumed initial public offering price.............................        $9.00
  Net tangible book value per share at December 31, 1996(1)....... $0.74
  Increase attributable to new investors..........................  1.49
                                                                    ----

Dilution to new investors(1)......................................        $6.77
                                                                           ====

         If the Over-Allotment Option is exercised in full, the pro forma net
tangible book value per share of Common Stock after the Offering would be $2.42,
which would result in dilution to new investors in this Offering of $6.58 per
share of Common Stock.

         The following table shows, at December 31, 1996, a comparison of the
total number of shares of Common Stock purchased from the Company, the total
consideration paid and the average price paid per share by existing shareholders
and to be paid by investors who purchase shares of Common Stock in the Offering
(at an assumed initial public offering price of $9.00 per share):

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

INTRODUCTION

         The Company was incorporated on December 8, 1995 and acquired ITC on
December 18, 1995 by issuing 2,500,000 shares of Common Stock valued at
$500,000. ITC was incorporated on May 15, 1995 and, prior to its acquisition,
ITC's activities consisted of research and development of telephony
communications software for use on the Internet and LANs and WANs. From December
8, 1995 to December 31, 1995 the Company's operating activities related
primarily to raising initial capital and continuing ITC's research and
development. The Company released its first product in February 1996 and, for
accounting purposes, emerged from the development stage during 1996. Since
inception, the Company has raised an aggregate of $8,652,090, net of offering
costs, through private offerings of its equity securities. See "Liquidity and
Capital Resources."

         The Company generates revenues from products, licenses and fees for
services provided. The Company's products are licensed primarily to telephone
companies, network service providers, corporate customers and directly to
individual client software end-users. Service revenues consist of customer
support 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,
1996, the Company had an accumulated deficit of $3,508,187. The limited
operating history of the Company makes its future results of operations
difficult to predict. In addition, 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, technical difficulties with respect to the use of products developed
by the Company and general economic conditions. See "Risk Factors."

                                      -22-

RESULTS OF OPERATIONS

         YEAR ENDED DECEMBER 31, 1996, AS COMPARED TO 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, 1996 were $867,117. The
Company had no revenues during 1995 when the Company's initial products were in
the process of development. Net revenues during 1996 were primarily generated
from license fees paid by individual client software end-users and license fees
received from Creative, a strategic partner of the Company, for providing it
with the right to distribute certain products using the Company's WebPhone
client software. Creative, the Company's largest customer, accounted for 44% of
total net revenues in the year ended December 31, 1996 and is expected to
continue to be a principal customer of the Company in the near future. See
"Business - Strategic Alliances".

         The Company's operating expenses have increased significantly since
inception. This trend reflects the costs associated with the development of the
organization's infrastructure, rapid growth and increased efforts to
commercialize the Company's systems and products. The Company believes that
continued expansion of its operations is essential to continue the enhancement
of its existing products and to facilitate the development of new technologies,
in addition to expanding sales and marketing efforts in order to gain product
acceptance in the targeted markets. As a consequence, the Company intends to
continue to increase expenditures in all operating areas.

         Cost of revenues primarily consists of direct product costs, costs of
engineering services and certain costs associated with providing customer
support. Cost of revenues were $47,129 in the year ended December 31, 1996. The
Company had no cost of revenues during 1995.

         Research and development expenses primarily consist of employee
compensation, computer hardware and software utilized in product development,
and equipment depreciation. Research and development expenses were $2,255,644
for the year ended December 31, 1996 and $203,339 during 1995. The increase in
research and development expenses was primarily due to increased costs
associated with developing, enhancing and expanding upon the Company's products
and systems and the expansion of the research development staff to 23 employees
at December 31, 1996. All research and development costs have been expensed as
incurred. Although research and development for the Company's initial products
and systems was substantially completed during 1996, the Company intends to
significantly increase research and development expenses in future periods to
perform product enhancements and new product development to establish and
maintain a competitive advantage. In connection with the acquisition of ITC,
$556,982 of purchased research and development was charged to expense. See Note
2 to the consolidated financial statements.

         Marketing and sales expenses primarily consist of employee
compensation, travel expenses, trade shows and costs of promotional materials.
Marketing and sales expenses were

                                      -23-


<PAGE>

$722,353 for the year ended December 31, 1996. The Company had no marketing and
sales expenses during 1995. Marketing and sales expenses during 1996 were the
result of the creation and expansion of the Company's marketing, sales and
customer support infrastructure, which included 23 employees at December 31,
1996 and increased expenses associated with the promotion and marketing of the
Company's products and systems. The Company intends to continue to intensify and
expand its marketing and sales effort and, as a result, intends to significantly
increase marketing and sales expenses in future periods.

         General and administrative expenses primarily consist of employee
compensation, professional services, rent and office expenses. General and
administrative expenses were $836,791 for the year ended December 31, 1996 and
$62,844 during 1995. The Company intends to increase general and administrative
expenses in future periods in order to expand the organization's infrastructure,
including the addition of finance and administrative personnel.

         Income taxes for the year ended December 31, 1996 totaled $43,000. Such
taxes were attributable to income taxes paid to the Singapore government related
to license fees received pursuant to the agreement with Creative. The Company
paid no income taxes during 1995.

         As of December 31, 1996, the Company had approximately $3,254,000 of
federal and state net operating loss carryforwards which, if not utilized, will
begin to expire in 2009. Under the Tax Reform Act of 1986, the amounts of and
the benefits from net operating loss carryforwards may be impaired in certain
circumstances. Events which may cause such 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. The effect of any limitation, if imposed, is not expected to be
material. As of December 31, 1996, the Company has provided a valuation
allowance for the full amount of the deferred tax asset resulting from the net
operating loss carryforwards due to the uncertainty as to the utilization of the
net operating loss carryforwards, primarily as a result of considering such
factors as the Company's limited operating history and the operating losses
incurred to date. See Note 7 to the consolidated financial statements.

LIQUIDITY AND CAPITAL RESOURCES

         As of December 31, 1996, the Company had $6,294,697 in cash and cash
equivalents. Since inception, the Company has financed its operations through
the sale of equity securities in private transactions as described below.

         Net cash of $1,033,643 was used in operating activities during the year
ended December 31, 1996 and was primarily attributable to research and
development and building the corporate infrastructure, partially offset by
unearned revenue of $2,242,011 resulting from fees paid in advance for licensed
goods and engineering services not yet shipped and performed, respectively. Net
cash used in investing activities during the year ended December 31, 1996 was
$1,216,834 and primarily related to purchases of computer equipment.

                                      -24-


<PAGE>

         Net cash provided by financing activities for the year ended December
31, 1996 was $8,062,090 and was attributable to private offerings of equity
securities.

         In January 1996, the Company sold 1,204,000 shares of Common Stock at
$2.50 per share in a private offering raising $2,992,028, net of offering costs.
In January 1996, the Company issued stock options under the 1995 Plan to
purchase 250,000 shares of Common Stock for $2.50 per share to a consulting
firm, which assisted the Company with its private offering.

         In June 1996, the Company issued 207,679 shares of Common Stock to
Creative at a price of $5.05 per share raising $943,698, net of offering costs.
The Company also issued Creative an eighteen-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.

         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 (the "Motorola Warrant") to Motorola raising $3,993,864,
net of offering costs. In the event the Company consummates the Offering or any
other underwritten public offering of its Common Stock at a price of at least
$7.00 per share resulting in the receipt by the Company of net proceeds of not
less than $10,000,000, the Company, at its option, upon not less than 20
business days notice given prior to the planned closing date of such public
offering, may require Motorola to exercise the Motorola Warrant, provided,
however, that within 15 business days of receipt of the Company's notice,
Motorola may elect to cancel the Motorola Warrant unexercised.

         The Company has no material commitments other than those under office
and equipment leases. The Company anticipates that, based on its present plans
and assumptions, the net proceeds of the Offering combined with the Company's
existing capital resources and anticipated cash flows from operations will be
sufficient to enable it to maintain its current and planned operations for a
period of at least 12 months after consummation of the Offering. 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. Additional financings may result in dilution to existing shareholders.
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. See "Risk Factors - Possible Need for Additional
Capital."

                                    BUSINESS

OVERVIEW

         NetSpeak develops, markets, licenses, and supports a suite of
intelligent software modules which enable real-time, concurrent interactive
voice, video and data transmission over a packetized data network such as the
Internet, LANs and WANs. The Company believes that its technology is
strategically positioned to capitalize on the rudimentary shift in corporate
telecommunications philosophy as businesses seek to expand the functionality of
their communication systems as well as optimize their use of packetized data
networks, thereby eventually eliminating the redundancy inherent in maintaining
a traditional voice network simultaneously with a packetized data network.
Netspeak is currently marketing a user-friendly core communications technology
which enables, in a cost-effective manner, corporations and other users to
enhance the role of their packetized data networks to support concurrent voice,
video and data transmission. NetSpeak believes that as potential users become
increasingly educated as to the benefits of integrating the two networks,
significant revenue opportunities for the Company will be generated.

         The Company's software uses proprietary intelligent virtual circuit
switching technology to provide gateways between packetized data networks and
traditional voice transmission networks. The technology allows users to
integrate into packetized data networks a variety of features and functions
commonly found in traditional voice transmission networks, including ACD,
multi-point conferencing, interactive voice response services, messaging
services and least cost routing, as well as to expand network functionality by
offering additional features such as concurrent voice and data transmission and
video conferencing. The Company's virtual circuit switching technology provides
intelligent call routing to enable users to transparently communicate with each
other on a point-to-point basis. The Company believes that its products and
systems are designed to allow customers to integrate NetSpeak's technology into
their existing network infrastructures without the need for significant
upgrading, and can ultimately provide a complete software-based solution for the
delivery of concurrent real-time interactive voice, video and data
communications over packetized data networks.

         In order to facilitate and accelerate the acceptance of NetSpeak's
technology as well as enhance the marketing and distribution of its products and
systems, the Company has established a number of strategic alliances with
various telecommunications and computer industry leaders. Under 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 the various
distribution channels. The Company believes that these strategic alliances also
offer access to its strategic partners' leading edge technologies, as well as
insights into market trends and product development.

         In August 1996, the Company established a strategic alliance with
Motorola pursuant to which Motorola made a minority investment in the Company
and the Company granted Motorola a right of first negotiation on licenses of the
Company's technology as it applies to the cellular and cable communications
industries. Motorola is also conducting a number of end-user test trials

                                      -26-


<PAGE>

of systems which combine the Company's technology, products and systems with
those of Motorola.

         Beginning in June 1996, the Company also entered into a strategic
alliance with Creative, a world leader in the manufacture and distribution of
audio cards and multimedia computer peripherals. Pursuant to such alliance,
Creative made a minority investment in the Company. NetSpeak granted Creative a
world-wide license to market, distribute and bundle NetSpeak's WebPhone client
(or end-user) software under the Creative brand name in the retail distribution
channel and the Company and Creative are jointly developing various other
Internet-related software applications which use the Company's and Creative's
proprietary technologies, in such areas as radio broadcast.

         In August, 1996, the Company established a strategic alliance with
Rockwell, an industry leader in medium and high-end ACD systems. As part of this
alliance, the Company's gateway products and ACD systems are being integrated
into Rockwell's ACD systems. Beginning in November 1996, the Company entered
into a strategic alliance with Infonet, one of the largest commercial data
network carriers in the world. Pursuant to such alliance, the Company will
integrate its technology with Infonet's existing global data network, in order
to enhance Infonet's packetized data network for voice transmission. The Company
intends to seek to establish additional strategic alliances.

         In addition to marketing its technology products and systems with its
strategic partners, NetSpeak has begun to market its products directly to
end-users, including telephone companies, cable companies, and other common
carriers, large business enterprises, ACD manufacturers and other OEMs,
governmental and educational entities, as well as to distributors, such as SIs
and VARs. To date, such marketing efforts have been limited to direct contacts
with a number of these customers. NetSpeak is also marketing its WebPhone client
software products over the Internet, by advertising in computer periodicals and
through distribution agreements with over 700 ISPs worldwide. The Company is
currently developing an in-house marketing and sales infrastructure.

         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) establishing 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 and
develop new applications.

INDUSTRY BACKGROUND

         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 ACD, has centered on
circuit switching

                                      -27-


<PAGE>

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.

                                      -28-


<PAGE>

         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.

         There are many applications currently utilizing traditional telephony
that could benefit from various of 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 Internet Protocol ("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 service department of a customer to be transferred from
the Internet to the customer's LAN, route the call to the next available service
agent, provide the service agent with information regarding the call and
transfer the call to the customer's PBX for answer by the service agent.
NetSpeak's technology also facilitates the concurrent transmission of voice and
data over a packetized data network. NetSpeak's core communications technology
is the platform utilized in all of NetSpeak's 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

                                      -29-


<PAGE>

                  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 support the IP
                  protocol;

         /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; and

         /bullet/ can be embedded in firmware, including portable and handheld
                  devices.

         NetSpeak is conducting ongoing research and development to further
enhance its core technology, such as developing the plug-and-play processes that
allow for the addition of new software components such as voice and video
codecs, encryption "engines", animation controllers, user interfaces and
communications protocols, and providing dynamic swapping of these components.

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 telecommunications and computer industry leaders. Pursuant to 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

                                      -30-


<PAGE>

that these strategic alliances also offer access to its partners' leading edge
technologies. To date, the Company has established strategic alliances with
Motorola, Creative, Rockwell and Infonet and intends to seek to establish
additional strategic alliances.

         EXPAND INTERNAL MARKETING AND SALES EFFORTS

         The Company has recently hired a Vice President of Marketing to develop
an infrastructure to facilitate distribution of the Company's technology,
products and services. The Company is presently developing an in-house sales
force and expanding its direct marketing and sales efforts to end-users,
including telephone companies, cable companies and other common carriers, large
business enterprises, ACD manufacturers and other OEMs, and governmental and
educational entities, as well as to SIs, VARs and other distributors.

         EDUCATE THE MARKETPLACE

         Given the historical use of different infrastructures for voice and
data transmission, NetSpeak believes that it needs to educate its potential
customer base on how its core communications 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 intends to expand 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
applications.

PRODUCTS AND SYSTEMS

         NetSpeak's products and systems consist of four principal groups:
gateway products, business systems, server software and client (or end-user)
software products. NetSpeak's products and systems combine its various
intelligent software modules to provide applications that furnish each
particular product's desired features and functions.

         GATEWAY PRODUCTS

         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

                                      -31-


<PAGE>

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.

         WebPhone Gateway eXchange ("WGX") is NetSpeak's initial gateway
product. NetSpeak has developed two versions of the WGX, which differ primarily
in the types of interfaces they provide to the PSTN, the manner in which voice
compression is performed, and the maximum number of simultaneously supported
connection ports. The initial version of the WGX, the WGX-M, is PC-based,
provides standard analog interfaces to the PSTN network and is offered in sizes
up to 16 voice channels (ports). A second version, the WGX-MD, is PC-based,
provides digital T1 interface to the PSTN network, and is offered in sizes up to
24 ports. NetSpeak is also developing the WGX-L series. This series is based on
a NetSpeak proprietary hardware design which will provide digital T1 interfaces
to the voice network and will be offered in sizes up to 96 ports. The WGX-L
series will be designed to meet stringent central office requirements for
telephone company networks and offer a number of other systems management and
remote operations, administration and maintenance features.

         BUSINESS SYSTEMS

         NetSpeak's business systems consist of two product subgroups: call
center systems and PBX systems.

         CALL CENTER SYSTEMS. 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. In NetSpeak's call center systems, agents answer calls by
using NetSpeak's Agent WebPhone client software products that are running in
their individual PCs. Call center systems are high-visibility, traffic intensive
application environments, and therefore are usually much higher in cost than
simple business telephone systems. NetSpeak's call center systems can be
integrated with existing ACDs to provide voice transmission over a customer's
existing packetized data network without the need for significant upgrading of
the network infrastructure and ultimately can provide a customer with a
software-based solution to its call center requirements.

         NetSpeak's call center systems consist of:

         The WebPhone Automatic Call Distributor - Internet Attachment is the
basic component of this system and allows a user to integrate Internet-based
telephony with its existing circuit switched ACD. This system enables a call
center agent to know to which incoming-line on the existing ACD a specific
Internet voice call has been directed and forwards certain information to the
next available agent. With this information, the agent can use the NetSpeak's
WebPhone client software product running in its local PC to retrieve additional
information about the

                                      -32-


<PAGE>

incoming caller. This capability provides more information about the caller than
existing circuit switched ACDs.

         The WebPhone Virtual ACD 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 is a tool for facilitating the development
of the next generation of call centers. It integrates the capabilities of the
WebPhone Virtual-ACD 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 as packetized voice,
whether originated over the Internet, the user's Intranet or the PSTN, and all
caller information is presented to the agent in a uniform format.

         In addition, the Company is developing the WebPhone ACD-CTx. This
system will offer customized computer telephony interfaces between NetSpeak's
WGX and the customer's existing circuit switched ACD. ACDs, including most
telephone company Centrex-based ACD service offerings, require a specialized CTx
interface to integrate a NetSpeak system. The WebPhone ACD-CTx will preserve the
existing integral skills-based routing and other ACD vendor-specific value-added
functions, while integrating IP-delivered calls with regular PSTN calls.

         PBX SYSTEMS. PBX Systems are the basic business telephone systems which
service multiple users in an organization where employees need to communicate
with each other, as well as with persons outside the organization. NetSpeak's
PBX systems provide existing circuit switch PBX systems the ability to
communicate with NetSpeak WebPhone client software anywhere on a packetized data
network by bringing voice traffic from the PSTN into a NetSpeak PBX-based
system, and carrying all voice, video and data communication to every user in a
common packetized digital format.

         NetSpeak's PBX systems currently consist of:

         The WebPhone Virtual PBX allows a business to construct an in-house
voice network which delivers packetized voice to every PC. All calls between
users are carried over the packetized data network and there is no need to
install and maintain separate voice network wiring or separate databases of
information relative to individual users and their locations.

         The WebPhone Enterprise PBX combines the WebPhone Virtual PBX and WGX
to create an integrated system that allows voice traffic coming from the PSTN,
as well as voice traffic coming from packetized data networks, to be integrated
and delivered over the customer's existing network infrastructure to individual
end-users logged on to NetSpeak's WebPhone client software products.

                                      -33-

         SERVER SOFTWARE

         All key NetSpeak software (i) controls the connection process between
users, (ii) manages network operations, (iii) coordinates billing, (iv) provides
value-added features and functions to the users and (v) is designed to run on
PCs or larger workstation-type systems utilizing the Microsoft Windows NT
operating system. Since many networks need high levels of reliability, such as
common carrier networks, NetSpeak has incorporated certain contingency features
into its software such as enabling its server software to permit multiple copies
to run concurrently on the same network.

         NetSpeak's various software modules can be combined to construct
various types of voice transmission networks. These software modules include the
Global Information Server, which is responsible for finding the destination
party and coordinating the connection between users; the Control Center module,
which is the management control software for all of NetSpeak's products; the
DataBase Services module, which acts as an "event management utility" for
distributing activity messages relating to billing and other operations events;
and the ACD Server module, which is the key to NetSpeak's call center systems. A
variety of other support modules are under development, including the Credit
Processing Server, that is used for real-time collection and customer account
management and an Interactive Voice Response Server module which will guide a
caller through a series of information steps.

         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, winner of PC Magazines'
Editor's Choice (October 8, 1996) award, is the basis of all other NetSpeak
client software products including the Business WebPhone and the Agent WebPhone,
which are key components of NetSpeak's PBX and call center systems. NetSpeak's
other client software products include the Mini-WebPhone, a minimum-function
telephone which can be quickly downloaded by the end-users of a NetSpeak ACD
system and the Virtual WebPhone, which is integrated into the NetSpeak WGX and
is responsible for maintaining the connection with other WebPhones. In order to
maximize the amount of caller information provided to agents, the Company is
developing additional agent software which is designed to be used in conjunction
with NetSpeak's call center systems.

STRATEGIC ALLIANCES

         In order to facilitate and accelerate the acceptance of NetSpeak
technology as well as enhance the marketing and distribution of its products and
systems, the Company has established a number of strategic alliances with
various telecommunications and computer industry leaders. Under 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 the various
distribution channels currently utilized by such partners. The Company believes
that these strategic alliances also offer access to its partners' leading edge
technologies, as well as insights into market trends and product

                                      -34-


<PAGE>

development. The Company intends to seek additional strategic alliances.
Companies with which NetSpeak is currently participating in a strategic alliance
include:

         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 and cable communications industries. A designee of Motorola serves
on the Company's Board of Directors. See "Management-Directors and Executive
Officers" and "Certain Transactions".

         Motorola has become a customer of the Company and is conducting a
number of end-user test trials of systems that combine the Company's technology,
products and systems with those of Motorola.

         CREATIVE

         Beginning in June 1996, the Company entered into a strategic alliance
with Creative, producer of the Sound Blaster family of products and one of the
world's leaders in the manufacture and distribution of audio cards and
multimedia computer peripherals. Pursuant to the agreements between NetSpeak and
Creative, Creative made a minority investment in the Company and the Company
granted Creative a worldwide 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. The Company received
a fixed license fee upon execution of the agreement and will receive a fixed
royalty for each copy of the full version Internet telephone software products
sold at retail by Creative. NetSpeak and Creative subsequently expanded their
relationship to include a license granted on a royalty-free basis by Creative to
NetSpeak for Creative's video codec technology for a period to be coterminous
with the WebPhone technology license which was granted to Creative by the
Company. NetSpeak and Creative are also jointly developing other
Internet-related applications which use both the Company's and Creative's
proprietary technology in such areas as radio broadcast.

         ROCKWELL

         In August 1996, the Company established a strategic alliance with
Rockwell, an industry leader in medium to high end ACD systems. As part of this
alliance, the Company's gateway products and ACD systems are being integrated
into Rockwell ACD systems. The integration of NetSpeak's technology into
Rockwell ACD systems will enable call center agents to receive real-time voice
and data information transmitted from customers' voice-enabled web pages.
NetSpeak and Rockwell are cooperating on the marketing of these systems and both
companies have agreed to explore the joint development of a software solution
for the low-end ACD market.

                                      -35-


<PAGE>

         INFONET

         Beginning in November 1996, the Company entered into a strategic
alliance with Infonet, one of the largest commercial data network carriers in
the world. Pursuant to such alliance, the Company will integrate its technology
with Infonet's existing global data network to enhance concurrent voice and data
transmission over the network. In addition, Infonet has and is expected to
continue to purchase the Company's products in connection with the ongoing
operation of its voice enabled data network.

MARKETING AND SALES

         The principal target market for NetSpeak's products and systems
encompasses a wide variety of end-users, such as telephone companies, cable
companies and other common carriers, large business entities, ACD manufacturers
and other OEMS, and governmental and educational entities, as well as SIs, VARs
and other distributors.

         In addition to marketing its products and systems with its strategic
partners, NetSpeak has begun to market its products directly to end-users and
distributors. To date, such marketing efforts primarily have been limited to
direct contacts with a number of these customers. NetSpeak is also marketing its
WebPhone client software products over the Internet, by advertising in computer
periodicals, and through distribution agreements with over 700 ISPs worldwide.

         The Company has recently hired a Vice President of Marketing to develop
an infrastructure to facilitate distribution of the Company's technology,
products and production systems. NetSpeak is developing an in-house sales force
in order to focus its sales efforts on direct sales to end-users and
distributors. NetSpeak intends to divide its in-house sales force into groups,
each of which will focus on one or more categories of potential customers. In
addition to direct contact with potential customers, in-house marketing and
sales efforts will include direct mail, advertising, and other marketing
campaigns and attendance at industry trade shows, which in addition to
generating sales, are intended to educate potential customers as to the
features, functionality, cost effectiveness and other benefits of NetSpeak's
technology, products and systems. In addition, the Company's site on the World
Wide Web will permit prospective customers to obtain information about its
products and services, download software for evaluation and order certain
products. The Company intends to continue to intensify and expand its marketing
and sales efforts and, as a result, intends to significantly increase marketing
and sales expenses in future periods.

CUSTOMER SERVICE AND SUPPORT

         NetSpeak is committed to maintaining customer satisfaction and loyalty.
As of December 31, 1996, NetSpeak employed 18 technical representatives to
support and service its customer base. The Company intends to hire additional
technical customer representatives to support the expected increase in its
installed base for its business products, such as gateway products and

                                      -36-


<PAGE>

business systems. The Company also provides back-up support with respect to
NetSpeak technology, products and systems marketed by its strategic partners.

         The Company maintains a technical support hotline to answer customer
inquiries and provides an on-line database of technical product information. The
Company's support staff also responds to e-mail inquiries and monitors several
e-mail mailing lists. Customer support specialists diagnose and solve technical
problems related not only to the Company's products and systems but also to
other hardware and software with which the Company's products and systems may be
integrated. The Company tracks all support requests, through a series of
customer databases, including current status reports and historical customer
interaction logs. The Company uses customer feedback as a source of ideas for
product application improvements and enhancements.

         The Company intends to provide maintenance for all of its business
systems through a program of periodic technical upgrades. The price of a
NetSpeak business system includes 90 days of maintenance service. For a fee, the
Company will provide extended maintenance services to its business systems
customers and to certain volume purchasers of its client software products.

RESEARCH AND DEVELOPMENT

         The market for the Company's products is characterized by rapidly
changing technology, evolving industry standards, and frequent new product
introductions. Management believes that the Company's future success depends in
large part upon its ability to continue to enhance the functionality and uses of
its core technology. The Company believes that it can further improve its
technology which will allow it to enhance its existing products applications as
well as develop new applications.

         The Company intends to be involved in the review and establishment of
industry standards by actively participating in standard setting bodies such as
MIT's ITC (Internet Telephony Interoperability Consortium) consortium, VoIP
(Voice on IP) Forum, IMTC (Interoperable Multimedia Teleconference) and VON
(Voice on the Net) Coalition.

         The Company currently conducts the majority of its product development
efforts in-house. The Company also employs independent contractors, to a limited
degree, to assist with certain product development and testing activities and
intends to work with its strategic partners with a view to enhancing its
products. The Company has aggressively expanded its Research and Development
group from six software engineers as of December 31, 1995 to 23 software
engineers and support staff as of December 31, 1996. In 1996 and 1995 the
Company's research and development expenditures were approximately $2.3 million
and $200,000 respectively. All of the Company's research and development costs
have been expensed as incurred, including purchased research and development of
$566,982 in connection with the acquisition of ITC. 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.

                                      -37-


<PAGE>

COMPETITION

         The Company is unaware of any other company which competes directly
with the entire spectrum of products and systems it offers. The Company does,
however, face competition for each of its individual products and systems. The
Company competes with companies such as Vienna Systems, Lucent and VocalTec with
respect to its gateway products. Principal competitors for NetSpeak's
software-based business systems include companies such as Lucent. In the market
for client software products, the Company competes with VocalTec, Microsoft and
Intel, among others.

         The Company believes that the principal competitive factors affecting
its potential success include development; time-to-market; product features,
such as flexibility, scalability, interoperability, functionality and ease of
use; as well as product/vendor reputation, quality, performance, price, customer
service and support, and the overall effectiveness of its sales and marketing
efforts.

         The Company may also face further competition in all market segments
from companies in the telecommunications and computer industries which decide to
develop and market competitive technology, products or 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. In addition, the
Company competes with manufacturers of hardware-based business systems. 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

                                      -38-


<PAGE>

to grant the relief sough 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 nine U.S. utility patent
applications, seven U.S. provisional patent applications and one Patent
Cooperation Treaty patent application relating to various aspects of its
technology. 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. The Company sought advice of counsel relating to the 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.

         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 an agreement with one customer requiring the
Company to place its source code in escrow. This agreement provides that the
customer 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.

                                      -39-

         EMPLOYEES

         As of December 31, 1996, the Company employed 56 persons, including 41
in engineering and support and 15 in sales, marketing and administration. 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.

         FACILITIES

         The Company occupies approximately 10,000 square feet of space in Boca

Robert Kennedy, the Company's President and Chief Operating Officer, Shane D.
Mattaway, the Company's Executive Vice President and Chief Technical Officer,
John W. Staten, the Company's Chief Financial Officer and Harvey Kaufman, the
Company's Executive Vice President and Secretary. The employment agreements have
"rolling" two year terms, so that at all times the remaining term of the
agreement is two years. The employment agreements provide for annual salaries
initially set at $175,000, $150,000, $125,000, $90,000 and $75,000 for Messrs.

                                      -44-


<PAGE>

         Each employment agreement provides that the executive officer who is a
party thereto (the "Executive Officer") will continue to receive his salary for
a period of two years after termination of employment, if his employment is
terminated by the Company for any reason other than death, disability or Cause
(as defined in the employment agreement), or for a period of 12 months after
termination of the agreement as a result of the Executive Officer's disability,
and the Executive Officer's estate will receive a lump sum payment equal to one
year's salary plus a pro rata portion of any bonus to which the Executive
Officer is entitled upon termination of the employment agreement by reason of
the Executive Officer's death. Each employment agreement also prohibits the
Executive Officer from directly or indirectly competing with the Company for one
year after termination for any reason except a termination without Cause. If a
Change of Control (as defined in the employment agreement) occurs, the
employment agreement provides for the continued employment of the Executive
Officer for a period of two years following the Change of Control. In addition,
following the Change of Control, if the Executive Officer's employment is
terminated by the Company other than for Cause or by reason of the Executive
Officer's death or disability, or by the Executive Officer for certain specified
reasons (such as a reduction of compensation or a diminution of duties), the
Executive Officer will receive a lump sum cash payment equal to 200% of the cash
compensation received by the Executive Officer during the 12 calendar months
prior to such termination.

         The Company is also party to a two year employment agreement with
Steven F. Mills expiring in October 1998. The term of Mr. Mills' employment
agreement will automatically be extended for successive one-year terms unless
the Company or Mr. Mills gives written notice of its or his, respectively,
intent not to extend such agreement to the other party at least 60 days prior to
the then scheduled expiration date. Mr. Mills' annual salary is initially set at
$120,000. Mr. Mills employment agreement contains confidentiality and
non-competition provisions.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

         The Company does not have a compensation committee and all decisions
regarding executive compensation have been made by the Board of Directors as a
whole. See "Certain Transactions" with respect to the payment of legal fees to a
law firm of which A. Jeffry Robinson is a partner.

1995 STOCK OPTION PLAN

         Under the 1995 Plan, as amended, an aggregate of 2,700,000 shares of
Common Stock are reserved for issuance upon exercise of options ("1995 Plan
Options"). 1995 Plan Options

                                      -46-


<PAGE>

are designed to serve as incentives for retaining qualified and competent
directors, employees, consultants and independent contractors of the Company.

         The Company's Board of Directors, or a committee thereof, administers
and interprets the 1995 Plan and is authorized to grant 1995 Plan Options
thereunder to all eligible employees of the Company, including directors and
executive officers (whether or not employees) of the Company, as well as
consultants and independent contractors hired by the Company. The 1995 Plan
provides for the granting of both "incentive stock options" (as defined in
Section 422 of the Internal Revenue Code of 1986, as amended) and nonstatutory
stock options. Incentive stock options may only be granted, however, to
employees. 1995 Plan Options can be granted on such terms and at such prices as
determined by the Board, or a committee thereof, except that the per share
exercise price of incentive 1995 Plan Options will not be less than the fair
market value of the Common Stock on the date of grant and, in the case of an
incentive 1995 Plan Option granted to a 10% shareholder, the per share exercise
price will not be less than 110% of such fair market value as defined in the
1995 Plan.

         In accordance with the Internal Revenue Service Code, options granted
under the 1995 Plan that would otherwise qualify as incentive stock options will
not be treated as incentive stock options to the extent that the aggregate fair
market value of the shares covered by the incentive stock options which are
exercisable for the first time by any individual during any calendar year
exceeds $100,000.

         1995 Plan Options will be exercisable after the period or periods
specified in the option agreement, provided, however, that incentive 1995 Plan
Options vest in three annual installments commencing one year from the date of
grant. 1995 Plan Options granted are not exercisable after the expiration of ten
years from the date of grant and are not transferable other than by will or by
the laws of descent and distribution. Adjustments in the number of shares
subject to 1995 Plan Options can be made by the Board of Directors or the
appropriate committee in the event of a stock dividend or recapitalization
resulting in a stock split-up, combination or exchange of shares. Under the 1995
Plan, options may become immediately exercisable in the event of a change in
control or approval by stockholders of the Company of a merger, reorganization,
liquidation, dissolution or disposition of all or substantially all of the
assets of the Company. The 1995 Plan also authorizes the Company to make loans
to optionees to enable them to exercise their options.

         Non-statutory options to purchase an aggregate of 53,000 shares of
Common Stock previously granted under the 1995 Plan to various employees have
been exercised. As of the date of this Prospectus, the Company has 1995 Plan
Options outstanding to purchase an aggregate of 2,246,000 shares of Common Stock
at exercise prices ranging from $1.00 to $7.00. Of such options, 886,000 are
incentive stock options and 1,360,000 are non-statutory stock options.

         In December 1995, the Company acquired all of the issued and
outstanding capital stock of ITC by merger of ITC with a wholly-owned subsidiary
of the Company. As consideration for such, the Company issued an aggregate of
2,500,000 shares of Common Stock to the shareholders of ITC in exchange for all
of their ITC shares, including 1,000,000 shares to an affiliate of L. Richard
Mattaway and 850,000 shares to Shane D. Mattaway.

         In connection with the establishment of a strategic alliance, in August

additional 452,855 shares of Common Stock at a price of $5.50 per share for a
six year period expiring in August 2002 for an aggregate of $4,234,191. In the
event the Company consummates the Offering or any other underwritten public
offering of its Common Stock at a price of at least $7.00 per share resulting in
the receipt by the Company of net proceeds of not less than $10,000,000, the
Company, at its option, upon not less than 20 business days' notice given prior
to the planned closing date of such public offering, may require Motorola to
exercise the Motorola warrant, provided, however, that within 15 business days
of receipt of the Company's notice, Motorola may elect to cancel the Motorola
Warrant unexercised. In addition, Motorola was granted the right to designate
one member of the Company's Board of Directors so long as Motorola and its
affiliates beneficially own 5% or more of the Company's outstanding Common
Stock.

         A. Jeffry Robinson is a partner of the Miami, Florida law firm of Broad

affiliates take place on an arms-length basis and require the approval of a
majority of the independent directors of the Company.

                          DESCRIPTION OF CAPITAL STOCK

         The authorized capital stock of the Company consists of (i) 25,000,000
shares of Common Stock, par value $.01 per share, 9,698,532 shares of which will
be outstanding upon consummation of this Offering and (ii) 1,000,000 shares of
Preferred Stock, par value $.001 per share (the "Preferred Stock"), none of
which will be outstanding upon consummation of this Offering. As of the date of
this Prospectus, there were 100 holders of record of the Common Stock.

COMMON STOCK

         Subject to the rights of the holders of any Preferred Stock that may be
outstanding, each holder of Common Stock on the applicable record date is
entitled to receive such dividends as may be declared by the Board of Directors
out of funds legally available therefor, and, in the event of liquidation, to
share pro rata in any distribution of the Company's assets after payment or
providing for the payment of liabilities and the liquidation preference of any
outstanding Preferred Stock. Each holder of Common Stock is entitled to one vote
for each share held of record on the applicable record date on all matters
presented to a vote of shareholders, including the election of directors.
Holders of Common Stock have no cumulative voting rights or preemptive rights to
purchase or subscribe for any stock or other securities, and there are no
conversion rights or redemption or sinking fund provisions with respect to such
stock. All outstanding shares of Common Stock are, and the shares of Common
Stock issuable upon exercise of the Investor Warrants, the Agent's Option and
the Agent's Warrants will be, when issued, fully paid and nonassessable.

                                      -50-


<PAGE>

PREFERRED STOCK

         The Company's Board of Directors has the authority to issue 1,000,000
shares of Preferred Stock in one or more series and to fix, by resolution,
conditional, full, limited or no voting powers, and such designations,
preferences and relative, participating, optional or other special rights, if
any, and the qualifications, limitations or restrictions thereof, if any,
including the number of shares in such series (which the Board may increase or
decrease as permitted by Florida law), liquidation preferences, dividend rates,
conversion or exchange rights, redemption provisions of the shares constituting
any series and such other special rights and protective provisions with respect
to any class or series as the Board may deem advisable without any further vote
or action by the shareholders. Any shares of Preferred Stock so issued would
have priority over the Common Stock with respect to dividend or liquidation
rights or both and could have voting and other rights of shareholders. The
Company has no present plans to issue shares of Preferred Stock.

CERTAIN FLORIDA LEGISLATION

         Florida has enacted legislation that may deter or frustrate takeovers
of Florida corporations. The Florida Control Share Act generally provides that
shares acquired in a "control share acquisition" will not possess any voting
rights unless such voting rights are approved by a majority of the corporation's
disinterested shareholders. A "control share acquisition" is an acquisition,
directly or indirectly, by any person of ownership of, or the power to direct
the exercise of voting power with respect to, issued and outstanding "control
shares" of a publicly held Florida corporation. "Control shares" are shares,
which, except for the Florida Control Share Act, would have voting power that,
when added to all other shares owned by a person or in respect to which such
person may exercise or direct the exercise of voting power, would entitle such
person, immediately after acquisition of such shares, directly or indirectly,
alone or as a part of a group, to exercise or direct the exercise of voting
power in the election of directors within any of the following ranges: (i) at
least 20% but less than 33-1/3% of all voting power; (ii) at least 33-1/3% but
less than a majority of all voting power; or (iii) a majority or more of all
voting power. The Florida Affiliated Transactions Act generally requires
supermajority approval by disinterested shareholders of certain specified
transactions between a public corporation and holders of more than 10% of the
outstanding voting shares of the corporation (or their affiliates). Florida law
and the Company's Articles and Bylaws also authorize the Company to indemnify
the Company's directors, officers, employees and agents. In addition, the
Company's Articles and Florida law presently limit the personal liability of
corporate directors for monetary damages, except where the directors (i) breach
their fiduciary duties, and (ii) such breach constitutes or includes certain
violations of criminal law, a transaction from which the directors derived an
improper personal benefit, certain unlawful distributions or certain other
reckless, wanton or willful acts or misconduct.

TRANSFER AGENT

         The transfer agent for the Common Stock is American Stock Transfer &
Trust Company, New York, New York.

                         SHARES ELIGIBLE FOR FUTURE SALE

         Upon completion of this Offering, the Company will have 9,698,532
shares of Common Stock outstanding. Of these shares, the 2,000,000 shares of
Common Stock sold in this offering will be freely tradeable without restriction
under the Securities Act, except for any such shares which may be acquired by an
"affiliate" of the Company as that term is defined in Rule 144 under the
Securities Act (an "Affiliate"), which shares generally may be sold publicly
without registration under the Securities Act only in compliance with Rule 144.

         In general, under Rule 144 as currently in effect, if a period of at
least two years has elapsed since the later of the date the "restricted shares"
(as that phrase is defined in Rule 144) were acquired from the Company and the
date they were acquired from an Affiliate, then the holder of such restricted
shares (including an Affiliate) is entitled to sell a number of shares within
any three-month period that does not exceed the greater of 1% of the then
outstanding shares of the Common Stock or the average weekly reported volume of
trading of the Common Stock on the ________________________ during the four
calendar weeks preceding such sale. The holder may only sell such shares through
unsolicited brokers' transactions or directly to market makers. Sales under Rule
144 are also subject to certain requirements pertaining to the manner of such
sales, notices of such sales and the availability of current public information
concerning the Company. Affiliates may sell shares not constituting restricted
shares in accordance with the foregoing volume limitations and other
requirements but without regard to the two-year holding period.

         Under Rule 144(k), if a period of at least three years has elapsed
between the later of the date restricted shares were acquired from the Company
and the date they were acquired from an Affiliate, as applicable, a holder of
such restricted shares who is not an Affiliate at the time of the sale and has
not been an Affiliate for at least three months prior to the sale would be
entitled to sell the shares immediately without regard to the volume limitations
and other conditions described above. The Securities and Exchange Commission
(the "Commission") has proposed reducing the holding periods under Rule 144 and
Rule 144(k) to one year and two years, respectively. There can be no assurance
as to when, if ever, such proposal will be adopted by the Commission.

         The Company's executive officers and directors, and certain
shareholders who collectively own an aggregate of 7,698,532 shares of Common
Stock have agreed that they will not directly or indirectly, sell, offer,
contract to sell, make a short sale, pledge or otherwise dispose of any shares
of Common Stock (or any securities convertible into or exchangeable or
exercisable for any other rights to purchase or acquire Common Stock other than
shares of Common Stock issuable upon exercise of outstanding options) owned by
them, for a period of nine months after the date of this Prospectus, without the
prior written consent of Josephthal.

         After the nine month period, 5,428,000 of the shares subject to the
sale restriction will be eligible for sale in the public market pursuant to Rule
144 under the Securities Act, subject to the volume limitations and other
restrictions contained in Rule 144. The remaining 2,270,532

                                      -52-


<PAGE>

of such shares will become eligible for sale subject to the restrictions of Rule
144 at varying times from January 1998 to January 1999.

         The Company has granted to Motorola and Creative certain demand and
piggy-back registration rights under the Securities Act, with respect to the
shares of Common Stock beneficially owned by them.

         Prior to this Offering, there has been no market for the Common Stock
of the Company. The Company can make no predictions as to the effect, if any,
that sales of shares of Common Stock or the availability of shares of Common
Stock for sale will have on the market price prevailing from time to time.
Nevertheless, sales of significant amounts of shares of Common Stock in the
public market, or the perception that such sales may occur, could adversely
affect prevailing market prices.

                                  UNDERWRITING

         The Underwriters named below, (the"Underwriters"), for whom Josephthal
Lyon & Ross Incorporated is acting as the Representative, have severally agreed,
subject to the terms and conditions of the Underwriting Agreement
(the"Underwriting Agreement"), to purchase from the Company, and the Company has
agreed to sell to the Underwriters on a firm commitment basis, the respective
number of shares of Common Stock set forth below opposite their names:

                                                              =========

         The Underwriters are committed to purchase all the shares of Common
Stock offered hereby, if any of such shares are purchased. The Underwriting
Agreement provides that the obligations of the several Underwriters are subject
to the conditions precedent specified therein.

         The Company has been advised by the Representative that the
Underwriters initially propose to offer the Common Stock to the public at the
initial public offering price set forth on the cover page of this Prospectus and
to certain dealers at such price less concessions of not in excess of $______
per share of Common Stock. Such dealers may re-allow a concession not in excess
of $______ per share of Common Stock to other dealers. After the commencement of
the Offering, the public offering price, concession and reallowance may be
changed.

         The Representative has advised the Company that they do not anticipate
sales to discretionary accounts by the Underwriters to exceed five percent of
the securities offered by the Company hereby.

         The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act. The Company has
also agreed to pay the Representative an expense allowance on a non-accountable
basis equal to one and one-half percent of the gross proceeds of this Offering,
of which $35,000 has been paid to date.

         The Underwriters have been granted an option by the Company,
exercisable within 30 days of the date of this Prospectus, to purchase up to an
additional 300,000 shares of Common Stock at the initial public offering price
per share of Common Stock offered hereby, less underwriting discounts and the
non-accountable expense allowance. Such option may be exercised solely for the
purpose of covering over-allotments, if any, incurred in the sale of the shares
offered hereby. To the extent such option is exercised, in whole or in part,
each

                                      -54-


<PAGE>

Underwriter will have a firm commitment, subject to certain conditions, to
purchase the number of the additional shares of Common Stock proportionate to
its initial commitment.

         Holders of 7,698,532 shares of the Company's Common Stock, including
each officer, director and principal stockholder of the Company, have executed
agreements pursuant to which they have agreed not to sell or otherwise dispose
of their shares for a period of nine months from the date of this Prospectus
without the prior written consent of Josephthal. An appropriate legend shall be
marked on the face of the certificates representing all of such securities.

         Prior to the Offering, Josephthal was retained to provide financial
advisory services to the Company, such as the development of its business plan
to be used in anticipation of an offering of securities. In consideration for
such services, the Company has agreed to sell to Josephthal, for nominal
consideration, the Advisor's Warrants to purchase from the Company 200,000
shares of Common Stock. The Advisor's Warrants are initially exercisable at a
price per share equal to 120% of the initial public offering price for a period
of four years commencing one year after the date of this Prospectus and are
restricted from sale, transfer, assignment or hypothecation for a period of
twelve months from the date hereof, except to officers of Josephthal. The
Advisor's Warrants also provide for adjustment in the number of shares of Common
Stock issuable upon the exercise thereof as a result of certain subdivisions and
combinations of the Common Stock. The Advisor's Warrants grant to the holders
thereof certain rights of registration for the securities issuable upon exercise
of the Advisor's Warrants.

         Prior to this Offering, there has been no public market for the Common
Stock. Consequently, the initial public offering for the Common Stock has been
determined by negotiations between the Company and the Representative and is
not necessarily related to the Company's asset value, net worth or other
established criteria of value. The factors considered in such negotiations, in
addition to prevailing market conditions, included the history of and prospects
for the industry in which the Company competes, an assessment of the Company's
management, the prospects of the Company, its capital structure and certain
other factors as were deemed relevant.

         The foregoing is a summary of the principal terms of the agreements
described above and does not purport to be complete. Reference is made to a copy
of each such agreement which are filed as exhibits to the Registration
Statement. See "Additional Information."

                                  LEGAL MATTERS

         The validity of the shares of Common Stock offered hereby will be
passed upon for the Company by Broad and Cassel, a partnership including
professional associations, Miami, Florida. A. Jeffry Robinson, a partner of
Broad and Cassel is a director of the Company and owns 100,000 shares of Common
Stock and options to purchase 75,000 shares of Common Stock. Orrick, Herrington
& Sutcliffe LLP, New York, New York, has acted as counsel to the Underwriters in
connection with this Offering.

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, 1995 and 1996, 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
year ended December 31, 1996. 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, 1995
and 1996, 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 year ended December 31, 1996 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 and its subsidiary (the
      "Company") develops, markets, licenses, and supports a suite of
      intelligent software modules, 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. In addition, the Company's
      products and systems are new and 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, 1996, the Company had an accumulated deficit of
      $3,508,187. 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 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.

      The Company 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 NetSpeak Corporation, including ITC on a
      consolidated basis from the date of its acquisition, as of December 31,
      1995 and 1996 and for the period from December 8, 1995 (inception) to
      December 31, 1995 and for the year ended December 31, 1996. See Note 2.

      CONSOLIDATION - The consolidated financial statements include the accounts
      of the Company 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

                                     F-7
<PAGE>

      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.

      NET LOSS PER SHARE - Net loss per share was calculated by dividing net
      loss by the weighted average number of common shares outstanding during
      1996 adjusted for the effect of common stock equivalents, consisting of
      stock options and warrants, using the treasury stock method with an
      estimated initial public offering price of $9.00 per share. Pursuant to
      the requirements of the Securities and Exchange Commission, common stock
      issued by the Company during the twelve months immediately preceding the
      planned initial public offering, plus the number of common equivalent
      shares pursuant to the grant of common stock options or warrants during
      the same period, have been included in the calculation of the shares used
      in computing net loss per share as if they were outstanding for all of
      1996. The Company issued 1,710,000 stock options prior to February 1,
      1996, which were not included in weighted average shares outstanding
      because such options were issued prior to the twelve months immediately
      preceding the proposed offering and the effect on net loss per share would
      be anti-dilutive.

      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. Statement of Financial Accounting
      Standard ("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.

      CASH AND CASH EQUIVALENTS - Cash and cash equivalents include cash and
      short-term investments purchased with a maturity of three months or less.

                                    F-8
<PAGE>

      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.

      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
      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, 1995 and 1996 in the carrying value and
      fair value.

      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.


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 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:


          Equipment acquired                                      $    24,527
          Purchased research and development                          556,982
          Accounts payable assumed                                    (43,927)
          Acquisition costs, including cash overdraft assumed         (37,582)
                                                                  -----------
          Common stock issued                                     $   500,000
                                                                  ===========


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 $128,200.
                                     F-9

<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 shares of common
      stock for $2.50 per share in a private placement raising $2,992,028, 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, $271,339, was recorded as a cost of the
      offering. The option is exercisable through 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 $943,698, net of offering costs. The Company also
      issued Creative an eighteen-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. The Company will record as
      an expense the fair value, $66,217, of the warrant if the product
      distribution requirement becomes likely to be met. At December 31, 1996 no
      amounts have been recorded. The Company derived 44% of its revenues for
      the year ended December 31, 1996 and at December 31, 1996, had $300,000 in
      accounts receivable from Creative.

      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 $3,993,864, net of offering costs. In the event the Company
      consummates an underwritten public offering of its common stock at a price
      of at least $7.00 per share resulting in the receipt by the Company of net
      proceeds of not less than $10,000,000, the Company, at its option, upon
      not less than 20 business days notice given prior to the planned closing
      date of such public offering, may require Motorola to exercise the
      warrant, provided, however, that within 15 business days of receipt of the
      Company's notice, Motorola may elect to cancel the warrant unexercised.

      Employees exercised stock options to purchase 53,000 shares of common
      stock for $132,500 during the year ended 1996.

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

      Shareholders owning 5,100,000 shares of the Company's common stock have
      entered into a Shareholders Agreement which, among other matters, provides
      for restrictions on the sale or transfer of shares by such shareholders
      and specifies procedures for the election of directors. The Shareholders
      Agreement terminates upon the consummation of an initial public offering
      by the Company.

5.    STOCK  BASED COMPENSATION

      The Company may grant stock options under the 1995 Stock Option Plan (the
      "Plan) to key employees, consultants, officers and directors for up to 2.7
      million shares of common stock. Under the Plan, 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 3 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, 1995 and 1996, and
      changes during the periods ended on those dates is presented below:

</TABLE>

      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 ,on a
      pro forma basis, for 1995 and 1996 would have been $292,183 or $0.04 per
      share and $3,122,726 or $0.38 per share, respectively.

      The fair value of each employee stock option grant has been estimated on
      the date of grant using the Black-Scholes option pricing model with the
      following assumptions: dividend yield 0%, expected volatility 0%,
      risk-free interest rates ranging between 5.39% and 6.77%, and an expected
      life of 5 years.

6.    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, 1996 are as follows:


            Year ending December 31,
            ------------------------
                      1997                $   138,025
                      1998                    142,086
                      1999                    137,734
                      2000                      5,713
                                          -----------
                                          $   423,558
                                          ===========


      Rent expense for the periods ended December 31, 1995 and 1996 was $1,000
      and $67,000, 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. No matching
      contributions were made during the year ended December 31, 1996. The
      Company pays the administrative costs of the plan.

      The Company has entered into employment agreements with six officers with
      initial salaries aggregating $735,000 annually. The terms of these
      agreements are for two years.

                                     F-12
<PAGE>

      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 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.

      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.

      7. INCOME TAXES

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

                                                 December 31,
                                                    1996
                                                 -----------
      Current - Foreign                          $   225,000
      Deferred - Foreign                            (182,000)
                                                 -----------
                                                 $    43,000
                                                 ===========


      Income taxes for the year ended December 31, 1996 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, 1995 and
      1996, the Company had deferred tax assets as follows:

                                    F-13
<PAGE>
<TABLE>
<CAPTION>
                                                  December 31,      December 31,
                                                     1995              1996

     Deferred tax assets:

      Unearned revenue - foreign                 $       --         $    182,000
      Net operating loss carryforwards                110,000          1,291,000
      Valuation allowance                            (110,000)        (1,291,000)
                                                 ------------       ------------
           Net deferred tax asset                $       --         $    182,000
                                                 ============       ============
</TABLE>

      The valuation allowance 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, the Company had approximately $ 3,254,000 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, 1996, the effect of such
      limitations, if imposed, is not expected to be material.

ITEM 15.          RECENT SALE OF UNREGISTERED SECURITIES.

                  The following sets forth the Registrant's sale of its
securities within the last three years, which securities were not registered
under the Securities Act:

                  1. Upon incorporation of the Company in December 1995, the
Company sold an aggregate of 2,950,000 shares of Common Stock to various
executive officers, directors and advisors for an aggregate of $590,000,
including 1,750,000 shares to Stephen R. Cohen, 500,000 shares to Robert
Kennedy, 250,000 shares to Harvey Kaufman, and 100,000 shares to each of L.
Richard Mattaway and A. Jeffry Robinson.

                  2. In December 1995, upon the acquisition by the Company of
all of issued and outstanding capital stock of Internet Telephone Company
("ITC") by merger of ITC with a wholly-owned subsidiary of the Company, in
connection therewith, the Company issued an aggregate of 2,500,000 shares of
Common Stock to the shareholders of ITC in exchange for their ITC shares,
including 1,000,000 shares to an affiliate of L. Richard Mattaway and 850,000
shares to Shane D. Mattaway.

                  3. From January to February 1996, the Company sold an
aggregate of 1,204,000 shares of Common Stock at a price of $2.50 per share to
53 persons in a private offering for an aggregate of $3,010,000. No commissions
were paid in connection with such private offering. In January 1996, the Company
issued stock options under the 1995 Plan to purchase 250,000 shares of Common
Stock for $2.50 per share to a consulting firm, which assisted the Company with
its private offering.

                  4. From January to April, 1996, the Company issued an
aggregate of 53,000 shares of Common Stock to six employees pursuant to the
exercise of stock options.

                  5. In January, 1996, the Company issued an aggregate of 14,000
shares of Common Stock to an investment banking firm which assisted the Company
in establishing certain of its strategic alliances.

                  6. In June 1996, the Company sold 207,679 shares of Common
Stock to Creative Technology, Ltd. ("Creative") for an aggregate of $1,048,779.
The Company also issued to Creative a 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.

                  7. In August 1996, the Company sold 769,853 shares of Common
Stock 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 (the "Motorola Warrant") to Motorola, Inc. ("Motorola") for an aggregate of
$4,234,191. In the event the Company consummates an underwritten public offering
of its Common Stock at a price of at least $7.00 per share resulting in the
receipt by the Company of net proceeds of not less than $10,000,000, the
Company, at


<PAGE>

its option, upon not less than 20 business days' notice given prior to the
planned closing date of such public offering, may require Motorola to exercise
the Motorola Warrant, provided, however, that within 15 business days of receipt
of the Company's notice, Motorola may elect to cancel the Motorola Warrant
unexercised.

                  The above securities were all issued without registration
under the Securities Act by reason of the exemption from registration afforded
by the provisions of Section 4(2) thereof, as transactions by an issuer not
involving a public offering, each recipient of securities having delivered
appropriate investment representations to Registrant with respect thereto and
having consented to the imposition of restrictive legends upon the certificates
evidencing such securities.

ITEM 17.          UNDERTAKINGS.

                  The Registrant hereby undertakes:

                  (1) To file, during any period in which it offers or sells
securities, a post-effective amendment to this Registration Statement to:

                            (i) Include any prospectus required by Section
                  10(a)(3) of the Securities Act;

                           (ii) Reflect in the prospectus any facts or events
                  which, individually or together, represent a fundamental
                  change in the information in the Registration Statement.
                  Notwithstanding the foregoing, any increase or decrease in
                  volume of securities offered (if the total dollar value of
                  securities offered would not exceed that which was registered)
                  and any deviation from the low or high end of the estimated
                  maximum offering range may be reflected in the form of
                  prospectus filed

<PAGE>

                  with the Commission pursuant to Rule 42(b) if, in the
                  aggregate, the changes in volumes and price represent no more
                  than a 20% change in the maximum aggregate offering price set
                  forth in the "Calculation of Registration Fee" table in the
                  effective registration statement; and

                          (iii) Include any additional or changed material
                  information on the plan of distribution.

                  (2) For determining liability under the Securities Act, treat
each post-effective amendment as a new registration statement of the securities
offered, and the offering of the securities at that time to be the initial bona
fide offering.

                  (3) To file a post-effective amendment to remove from
registration any of the securities that remain unsold at the end of the
offering.

                  (4) To provide to the Underwriters at the closing specified in
the underwriting agreement certificates in such denominations and registered in
such names as required by the underwriter to permit prompt delivery to each
purchaser.

                  (5) Insofar as indemnification for liabilities arising under
the Securities Act may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that, in the opinion of the Securities and
Exchange Commission, such indemnification is against public policy as expressed
in the Securities Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense or any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

                  (6) For purposes of determining any liability under the
Securities Act, the information omitted from the form of prospectus filed as
part of this registration statement in reliance upon Rule 430A and contained in
a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4)
or 497(h) under the Securities Act shall be deemed to be part of this
registration statement as of the time it was declared effective.

                  (7) For the purpose of determining any liability under the
Securities Act, each post-effective amendment that contains a form of prospectus
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

                  Upon your request, as provided in SECTION 2(b) of this
Agreement, the Company shall also sell to the Underwriters, acting severally and
not jointly, up to an additional 300,000 shares of Common Stock for the purpose
of covering over-allotments, if any (the "Option Shares"). The Firm Shares and
the Option Shares are sometimes hereinafter referred to as the "Shares." The
Company also proposes to issue and sell to Josephthal warrants (the "Advisor's
Warrants") pursuant to the Advisor's Warrant Agreement (the "Advisor's Warrant
Agreement") for the purchase of an additional 200,000 shares of Common Stock.
The shares of Common Stock issuable upon exercise of the Advisor's Warrants are

Advisor's Shares (collectively, hereinafter referred to as the "Securities") are
more fully described in the Registration Statement and the Prospectus referred
to below.

                  1. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company
represents and warrants to, and agrees with, each of the Underwriters as of the
date hereof, and as of the Closing Date (hereinafter defined) and the Option
Closing Date (hereinafter defined), if any, as follows:

                  (a) The Company has prepared and filed with the Securities and
Exchange Commission (the "Commission") a registration statement, and an
amendment or amendments thereto, on Form S-1 (No. 333-______), including any
related preliminary prospectus ("Preliminary Prospectus"), for the registration
of the Firm Shares and the Option Shares under the Securities Act of 1933, as
amended (the "Act"), which registration statement and amendment or amendments
have been prepared by the Company in conformity with the requirements of the
Act, and the rules and regulations (the "Regulations") of the Commission under
the Act. The Company will promptly file a further amendment to said registration
statement in the form heretofore delivered to the Underwriters, and will not
file any other amendment thereto to which the Underwriters shall have objected
in writing after having been furnished with a copy thereof. Except as the
context may otherwise require, such registration statement, as amended, on file
with the Commission at the time the registration statement becomes effective
(including the prospectus, financial statements, schedules, exhibits and all
other documents filed as a part thereof or incorporated therein (including, but
not limited to those documents or information incorporated by reference therein)
and all information deemed to be a part thereof as of such time pursuant to
paragraph (b) of Rule 430(A) of the Regulations)), is hereinafter called the
"Registration Statement", and the form of prospectus in the form first filed
with the Commission pursuant to Rule 424(b) of the Regulations, is hereinafter
called the "Prospectus." For purposes hereof, "Rules and Regulations" mean the
rules and regulations adopted by the Commission under either the Act or the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), as applicable.

                  (b) Neither the Commission nor any state regulatory authority
has issued any order preventing or suspending the use of any Preliminary
Prospectus, the Registration Statement or the Prospectus or any part of any
thereof and no proceedings for a stop order suspending the effectiveness of the
Registration Statement or any of the Company's securities have been instituted
or are pending or to the Company's knowledge, threatened. Each of the
Preliminary Prospectus, Registration Statement and Prospectus at the time of
filing thereof conformed with the requirements of the Act and the Rules and
Regulations, and none of the Preliminary Prospectus, Registration Statement or
Prospectus at the time of filing thereof contained an untrue statement of a
material fact or omitted to state a material fact required to be stated therein
and necessary to make the statements therein, in light of the circumstances
under which they were made, not misleading, PROVIDED, HOWEVER, that this
representation and warranty does not apply to statements made or statements
omitted in reliance upon and in conformity with written information furnished to
the Company with respect to the Underwriters by or on behalf of the Underwriters
expressly for use in such Preliminary Prospectus, Registration Statement or
Prospectus.

<PAGE>



                  (c) When the Registration Statement becomes effective and at
all times subsequent thereto up to the Closing Date and each Option Closing
Date, if any, and during such longer period as the Prospectus may be required to
be delivered in connection with sales by the Underwriters or a dealer, the
Registration Statement and the Prospectus will contain all statements which are
required to be stated therein in accordance with the Act and the Rules and
Regulations, and will conform to the requirements of the Act and the Rules and
Regulations; neither the Registration Statement nor the Prospectus, nor any
amendment or supplement thereto, will contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, PROVIDED, HOWEVER, that this
representation and warranty does not apply to statements made or statements
omitted in reliance upon and in conformity with information furnished to the
Company in writing by or on behalf of any Underwriter expressly for use in the
Preliminary Prospectus, Registration Statement or Prospectus or any amendment
thereof or supplement thereto.

                  (d) The Company has been duly organized and is validly
existing as a corporation in good standing under the laws of the state of its
incorporation. The Company does not own an interest in any corporation,
partnership, trust, joint venture or other business entity. The Company is duly
qualified and licensed and in good standing as a foreign corporation in each
jurisdiction in which its ownership or leasing of any properties or the
character of its operations requires such qualification or licensing. The
Company has all requisite corporate power and authority, and the Company has
obtained any and all necessary authorizations, approvals, orders, licenses,
certificates, franchises and permits of and from all governmental or regulatory
officials and bodies (including, without limitation, those having jurisdiction
over environmental or similar matters), to own or lease its properties and
conduct its business as described in the Prospectus; the Company is and has been
doing business in compliance with all such authorizations, approvals, orders,
licenses, certificates, franchises and permits and all federal, state and local
laws, rules and regulations; and the Company has not received any notice of
proceedings relating to the revocation or modification of any such
authorization, approval, order, license, certificate, franchise, or permit
which, singly or in the aggregate, if the subject of an unfavorable decision,
ruling or finding, would materially and adversely affect the condition,
financial or otherwise, or the earnings, position, prospects, value, operation,
properties, business or results of operations of the Company. The disclosures in
the Registration Statement concerning the effects of federal, state and local
laws, rules and regulations on the Company's business as currently conducted and
as contemplated are correct in all material respects and do not omit to state a
material fact necessary to make the statements contained therein not misleading
in light of the circumstances in which they were made.

                  (e) The Company has a duly authorized, issued and outstanding
capitalization as set forth in the Prospectus, under "Capitalization" and
"Description of Capital Stock" and will have the adjusted capitalization set
forth therein on the Closing Date and the Option Closing Date, if any, based
upon the assumptions set forth therein, and the Company is not a party to or
bound by any instrument, agreement or other arrangement providing for it to
issue any capital stock, rights, warrants, options or other securities, except
for this Agreement, the Advisor's Warrant Agreement and as described in the
Prospectus. The Securities and all other securities issued or issuable by the
Company conform or, when issued and paid for, will

                                      -3-
<PAGE>

conform, in all respects to all statements with respect thereto contained in the
Registration Statement and the Prospectus. All issued and outstanding securities
of the Company have been duly authorized and validly issued and are fully paid
and non-assessable and the holders thereof have no rights of rescission with
respect thereto, and are not subject to personal liability by reason of being
such holders; and none of such securities were issued in violation of the
preemptive rights of any holders of any security of the Company or similar
contractual rights granted by the Company. The Securities are not and will not
be subject to any preemptive or other similar rights of any stockholder, have
been duly authorized and, when issued, paid for and delivered in accordance with
the terms hereof, will be validly issued, fully paid and non-assessable and will
conform to the description thereof contained in the Prospectus; the holders
thereof will not be subject to any liability solely by reason of being such
holders; all corporate action required to be taken for the authorization, issue
and sale of the Securities has been duly and validly taken; and the certificates
representing the Securities will be in due and proper form. Upon the issuance
and delivery pursuant to the terms hereof of the Securities to be sold by the
Company hereunder, the Underwriters or the Representatives, as the case may be,
will acquire good and marketable title to such Securities free and clear of any
lien, charge, claim, encumbrance, pledge, security interest, defect or other
restriction or equity of any kind whatsoever.

                  (f) The financial statements, including the related notes and
schedules thereto, included in the Registration Statement, each Preliminary
Prospectus and the Prospectus fairly present the financial position, income,
changes in cash flow, changes in stockholders' equity, and the results of
operations of the Company at the respective dates and for the respective periods
to which they apply and the pro forma financial information included in the
Registration Statement and Prospectus presents fairly, on a basis consistent
with that of the audited financial statements included therein, what the
Company's pro forma capitalization would have been for the respective periods
and as of the respective dates to which they apply after giving effect to the
adjustments described therein. Such financial statements have been prepared in
conformity with generally accepted accounting principles and the Rules and
Regulations, consistently applied throughout the periods involved. There has
been no adverse change or development involving a material prospective change in
the condition, financial or otherwise, or in the earnings, position, prospects,
value, operation, properties, business, or results of operations of the Company
whether or not arising in the ordinary course of business, since the date of the
financial statements included in the Registration Statement and the Prospectus,
and the outstanding debt, the property, both tangible and intangible, and the
business of the Company conform in all material respects to the descriptions
thereof contained in the Registration Statement and the Prospectus. Financial
information set forth in the Prospectus under the headings "Summary Consolidated
Financial Data," "Selected Consolidated Financial Data," "Capitalization," and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," fairly present, on the basis stated in the Prospectus, the
information set forth therein, have been derived from or compiled on a basis
consistent with that of the audited financial statements included in the
Prospectus.

                  (g) The Company (i) has paid all federal, state, local, and
foreign taxes for which it is liable and for which payment is due, including,
but not limited to, withholding taxes and amounts payable under Chapters 21
through 24 of the Internal Revenue Code of 1986

                                      -4-
<PAGE>

(the "Code"), and has furnished all information returns it is required to
furnish pursuant to the Code, (ii) has established adequate reserves for such
taxes which are not due and payable, and (iii) does not have any tax deficiency
or claims outstanding, proposed or assessed against it.

                  (h) No transfer tax, stamp duty or other similar tax is
payable by or on behalf of the Underwriters in connection with (i) the issuance
by the Company of the Securities, (ii) the purchase by the Underwriters of the
Securities to be sold by the Company hereunder and the purchase by Josephthal of
the Advisor's Warrants from the Company, (iii) the consummation by the Company
of any of its obligations under this Agreement or the Advisor's Warrant
Agreement, or (iv) resales of the Shares in connection with the distribution
contemplated hereby.

                  (i) The Company maintains insurance policies, including, but
not limited to, general liability, product liability and property insurance,
which insures the Company and its employees, against such losses and risks
generally insured against by comparable businesses. The Company (A) has not
failed to give notice or present any insurance claim with respect to any matter,
including but not limited to the Company's business, property or employees,
under the insurance policy or surety bond in a due and timely manner, (B) does
not have any disputes or claims against any underwriter of such insurance
policies or surety bonds or has not failed to pay any premiums due and payable
thereunder, or (C) has not failed to comply with all conditions contained in
such insurance policies and surety bonds. There are no facts or circumstances
under any such insurance policy or surety bond which would relieve any insurer
of its obligation to satisfy in full any valid claim of the Company.

                  (j) There is no action, suit, proceeding, inquiry,
arbitration, investigation, litigation or governmental proceeding (including,
without limitation, those having jurisdiction over environmental or similar
matters), domestic or foreign, pending or threatened against (or circumstances
that may give rise to the same), or involving the properties or business of, the
Company which (i) questions the validity of the capital stock of the Company,
this Agreement or the Advisor's Warrant Agreement or of any action taken or to
be taken by the Company pursuant to or in connection with this Agreement or the
Advisor's Warrant Agreement, (ii) is required to be disclosed in the
Registration Statement which is not so disclosed (and such proceedings as are
summarized in the Registration Statement are accurately summarized in all
material respects), or (iii) might materially and adversely affect the
condition, financial or otherwise, or the earnings, position, prospects,
stockholders' equity, value, operation, properties, business or results of
operations of the Company.

                  (k) The Company has full legal right, corporate power and
authority to authorize, issue, deliver and sell the Securities, enter into this
Agreement and the Advisor's Warrant Agreement and to consummate the transactions
provided for in such agreements; and this Agreement and the Advisor's Warrant
Agreement have each been duly and properly authorized, executed and delivered by
the Company. Each of this Agreement and the Advisor's Warrant Agreement
constitutes a legal, valid and binding agreement of the Company enforceable
against the Company in accordance with its terms, except (i) as such
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium, fraudulent conveyance or similar laws affecting
creditors' rights generally, (ii) as enforceability of any indemnification or
contribution provisions may be limited under applicable laws or the public
policies underlying

                                      -5-
<PAGE>

such laws and (iii) that the remedies of specific performance and injunctive and
other forms of equitable relief may be subject to equitable defenses and to the
discretion of the court before which any proceedings may be brought. None of the
Company's issue and sale of the Securities, execution or delivery of this
Agreement or the Advisor's Warrant Agreement, its performance hereunder and
thereunder, its consummation of the transactions contemplated herein and
therein, or the conduct of its business as described in the Registration
Statement, the Prospectus, and any amendments or supplements thereto, conflicts
with or will conflict with or results or will result in any breach or violation
of any of the terms or provisions of, or constitutes or will constitute a
default under, or result in the creation or imposition of any lien, charge,
claim, encumbrance, pledge, security interest, defect or other restriction or
equity of any kind whatsoever upon, any property or assets (tangible or
intangible) of the Company pursuant to the terms of, (i) the certificate of
incorporation or by-laws of the Company, (ii) any license, contract, indenture,
mortgage, deed of trust, voting trust agreement, stockholders agreement, note,
loan or credit agreement or any other agreement or instrument to which the
Company is a party or by which it is or may be bound or to which any of its
properties or assets (tangible or intangible) is or may be subject, or any
indebtedness, or (iii) any statute, judgment, decree, order, rule or regulation
applicable to the Company of any arbitrator, court, regulatory body or
administrative agency or other governmental agency or body (including, without
limitation, those having jurisdiction over environmental or similar matters),
domestic or foreign, having jurisdiction over the Company or any of its
activities or properties.

                  (l) Except as described in the Prospectus, no consent,
approval, authorization or order of, and no filing with, any court, regulatory
body, government agency or other body, domestic or foreign, is required for the
issuance of the Shares pursuant to the Prospectus and the Registration
Statement, the issuance of the Advisor's Warrants, the performance of this
Agreement and the Advisor's Warrant Agreement and the transactions contemplated
hereby and thereby, including without limitation, any waiver of any preemptive,
first refusal or other rights that any entity or person may have for the issue
and/or sale of any of the Shares or the Advisor's Warrants, except such as have
been or may be obtained under the Act or may be required under state securities
or Blue Sky laws in connection with the Underwriters' purchase and distribution
of the Shares, and the Advisor's Warrants to be sold by the Company hereunder
and under the Advisor's Warrant Agreement.

                  (m) All executed agreements, contracts or other documents or
copies of executed agreements, contracts or other documents filed as exhibits to
the Registration Statement to which the Company is a party or by which it may be
bound or to which any of its assets, properties or business may be subject have
been duly and validly authorized, executed and delivered by the Company, and
constitute the legal, valid and binding agreements of the Company, enforceable
against the Company, in accordance with their respective terms. The descriptions
in the Registration Statement of agreements, contracts and other documents are
accurate in all material respects and fairly present the information required to
be shown with respect thereto on Form S-1, and there are no contracts or other
documents which are required by the Act to be described in the Registration
Statement or filed as exhibits to the Registration Statement which are not
described or filed as required, and the exhibits which have been filed are in
all material respects complete and correct copies of the documents of which they
purport to be copies.

                                      -6-
<PAGE>

                  (n) Subsequent to the respective dates as of which information
is set forth in the Registration Statement and Prospectus, and except as may
otherwise be indicated or contemplated herein or therein, the Company has not
(i) issued any securities or incurred any liability or obligation, direct or
contingent, for borrowed money, (ii) entered into any transaction other than in
the ordinary course of business, or (iii) declared or paid any dividend or made
any other distribution on or in respect of its capital stock of any class, and
there has not been any change in the capital stock, or any material change in
the debt (long or short term) or liabilities or material adverse change in or
affecting the general affairs, management, financial operations, stockholders'
equity or results of operations of the Company.

                  (o) No default exists in the due performance and observance of
any term, covenant or condition of any license, contract, indenture, mortgage,
installment sale agreement, lease, deed of trust, voting trust agreement,
stockholders agreement, partnership agreement, note, loan or credit agreement,
purchase order, or any other agreement or instrument evidencing an obligation
for borrowed money, or any other material agreement or instrument to which the
Company is a party or by which the Company may be bound or to which the property
or assets (tangible or intangible) of the Company is subject or affected.

                  (p) The Company has generally enjoyed a satisfactory
employer-employee relationship with its employees and is in compliance with all
federal, state, local, and foreign laws and regulations respecting employment
and employment practices, terms and conditions of employment and wages and
hours. There are no pending investigations involving the Company by the U.S.
Department of Labor, or any other governmental agency responsible for the
enforcement of such federal, state, local, or foreign laws and regulations.
There is no unfair labor practice charge or complaint against the Company
pending before the National Labor Relations Board or any strike, picketing,
boycott, dispute, slowdown or stoppage pending or threatened against or
involving the Company or any predecessor entity, and none has ever occurred. No
representation question exists respecting the employees of the Company, and no
collective bargaining agreement or modification thereof is currently being
negotiated by the Company. No grievance or arbitration proceeding is pending
under any expired or existing collective bargaining agreements of the Company.
No labor dispute with the employees of the Company exists, or, is imminent.

                  (q) Except as described in the Prospectus, the Company does
not maintain, sponsor or contribute to any program or arrangement that is an
"employee pension benefit plan," an "employee welfare benefit plan," or a
"multiemployer plan" as such terms are defined in SECTIONS 3(2), 3(1) and 3(37),
respectively, of the Employee Retirement Income Security Act of 1974, as amended
("ERISA") ("ERISA Plans"). The Company does not maintain or contribute, now or
at any time previously, to a defined benefit plan, as defined in SECTION 3(35)
of ERISA. No ERISA Plan (or any trust created thereunder) has engaged in a
"prohibited transaction" within the meaning of SECTION 406 of ERISA or SECTION
4975 of the Code, which could subject the Company to any tax penalty on
prohibited transactions and which has not adequately been corrected. Each ERISA
Plan is in compliance with all reporting, disclosure and other requirements of
the Code and ERISA as they relate to any such ERISA Plan. Determination letters
have been received from the Internal Revenue Service with respect to each ERISA
Plan which is intended to comply with Code SECTION 401(a), stating that such
ERISA

                                      -7-
<PAGE>

Plan and the attendant trust are qualified thereunder. The Company has never 
completely or partially withdrawn from a "multiemployer plan."

                  (r) Neither the Company nor any of its employees, directors,
stockholders, partners, or affiliates (within the meaning of the Rules and
Regulations) of any of the foregoing has taken or will take, directly or
indirectly, any action designed to or which has constituted or which might be
expected to cause or result in, under the Exchange Act, or otherwise,
stabilization or manipulation of the price of any security of the Company to
facilitate the sale or resale of the Securities or otherwise.

                  (s) Except as otherwise disclosed in the Prospectus, none of
the patents, patent applications, trademarks, service marks, service names,
trade names and copyrights, and none of the licenses and rights to the foregoing
presently owned or held by the Company are in dispute or are in any conflict
with the right of any other person or entity. The Company (i) owns or has the
right to use, free and clear of all liens, charges, claims, encumbrances,
pledges, security interests, defects or other restrictions or equities of any
kind whatsoever, all patents, patent applications, trademarks, service marks,
service names, trade names and copyrights, technology and licenses and rights
with respect to the foregoing, used in the conduct of its business as now
conducted or proposed to be conducted without infringing upon or otherwise
acting adversely to the right or claimed right of any person, corporation or
other entity under or with respect to any of the foregoing and (ii) is not
obligated or under any liability whatsoever to make any payment by way of
royalties, fees or otherwise to any owner or licensee of, or other claimant to,
any patent, patent application, trademark, service mark, service name, trade
name, copyright, know-how, technology or other intangible asset, with respect to
the use thereof or in connection with the conduct of its business or otherwise.

                  (t) There is no action, suit, proceeding, inquiry,
arbitration, investigation, litigation or governmental or other proceeding,
domestic or foreign, pending or threatened (or circumstances that may give rise
to the same) against the Company which challenges the exclusive rights of the
Company with respect to any trademarks, trade names, service marks, service
names, copyrights, patents, patent applications or licenses or rights to the
foregoing used in the conduct of its business, or which challenge the right of
the Company to use any technology presently used or contemplated to be used in
the conduct of its business.

                  (u) The Company owns and has the unrestricted right to use all
trade secrets, know-how (including all other unpatented and/or unpatentable
proprietary or confidential information, systems or procedures), inventions,
technology, designs, processes, works of authorship, computer programs and
technical data and information (collectively herein "intellectual property")
that are material to the development, manufacture, operation and sale of all
products and services sold or proposed to be sold by the Company, free and clear
of and without violating any right, lien, or claim of others, including without
limitation, former employers of its employees; provided, however, that the
possibility exists that other persons or entities, completely independently of
the Company, or its employees or agents, could have developed trade secrets or
items of technical information similar or identical to those of the Company. The
Company is not aware of any such development of similar or identical trade
secrets or technical information by others.

                                      -8-

                  (v) The Company has good and marketable title to, or valid and
enforceable leasehold estates in, all items of real and personal property stated
in the Prospectus, to be owned or leased by it free and clear of all liens,
charges, claims, encumbrances, pledges, security interests, defects, or other
restrictions or equities of any kind whatsoever, other than those referred to in
the Prospectus, taxes, lessor's interests and liens for taxes not yet due and
payable.

                  (w) Deloitte & Touche LLP ("Deloitte") whose report is filed
with the Commission as a part of the Registration Statement, are independent
certified public accountants as required by the Act and the Rules and
Regulations.

                  (x) The Company has caused to be duly executed legally binding
and enforceable agreements pursuant to which the holders of the Common Stock and
holders of securities exchangeable or exercisable for or convertible into
__________ shares of Common Stock agreed not to, directly or indirectly, offer
to sell, sell, grant any option for the sale of, assign, transfer, pledge,
hypothecate, distribute or otherwise encumber or dispose of any shares of Common
Stock or securities convertible into, exercisable or exchangeable for or
evidencing any right to purchase or subscribe for any shares of Common Stock
(either pursuant to Rule 144 of the Rules and Regulations or otherwise) or
dispose of any beneficial interest therein for a period of not less than nine
(9) months following the effective date of the Registration Statement without
the prior written consent of Josephthal. During the nine (9) month period
commencing on the effective date of the Registration Statement, the Company
shall not, without the prior written consent of the Representative, sell,
contract or offer to sell, issue, transfer, assign, pledge, distribute, or
otherwise dispose of, directly or indirectly, any shares of Common Stock or any
options, rights or warrants with respect to any shares of Common Stock, except
up to 2,700,000 shares of Common Stock reserved for grants of options under the
Company's stock option plan as described in the Prospectus. The Company will
cause the Transfer Agent, as defined below, to mark an appropriate legend on the
face of stock certificates representing all of such securities and to place
"stop transfer" orders on the Company's stock ledgers.

                  (y) Except as described in the Prospectus under
"Underwriting," there are no claims, payments, issuances, arrangements or
understandings, whether oral or written, for services in the nature of a
finder's or origination fee with respect to the sale of the Securities hereunder
or any other arrangements, agreements, understandings, payments or issuance with
respect to the Company or any of its officers, directors, stockholders,
partners, employees or affiliates that may affect the Underwriters'
compensation, as determined by the National Association of Securities Dealers,
Inc. ("NASD").

                  (z) The Common Stock has been approved for quotation on the
Nasdaq National Market ("Nasdaq") [or admitted to trading on the American Stock
Exchange].

                  (aa) Neither the Company nor any of its officers, employees,
agents, or any other person acting on behalf of the Company, has, directly or
indirectly, given or agreed to give any money, gift or similar benefit (other
than legal price concessions to customers in the ordinary course of business) to
any customer, supplier, employee or agent of a customer or supplier, or official
or employee of any governmental agency (domestic or foreign) or

                                      -9-

instrumentality of any government (domestic or foreign) or any political party
or candidate for office (domestic or foreign) or other person who was, is, or
may be in a position to help or hinder the business of the Company (or assist
the Company in connection with any actual or proposed transaction) which (a)
might subject the Company, or any other such person to any damage or penalty in
any civil, criminal or governmental litigation or proceeding (domestic or
foreign), (b) if not given in the past, might have had a materially adverse
effect on the assets, business or operations of the Company, or (c) if not
continued in the future, might adversely affect the assets, business, operations
or prospects of the Company. The Company's internal accounting controls are
sufficient to cause the Company to comply with the Foreign Corrupt Practices Act
of 1977, as amended.

                  (bb) Except as set forth in the Prospectus, no officer,
director or stockholder of the Company, or any "affiliate" or "associate" (as
these terms are defined in Rule 405 promulgated under the Rules and Regulations)
of any of the foregoing persons or entities has or has had, either directly or
indirectly, (i) an interest in any person or entity which (A) furnishes or sells
services or products which are furnished or sold or are proposed to be furnished
or sold by the Company, or (B) purchases from or sells or furnishes to the
Company any goods or services, or (ii) a beneficial interest in any contract or
agreement to which the Company is a party or by which it may be bound or
affected. Except as set forth in the Prospectus under "Certain Transactions,"
there are no existing agreements, arrangements, understandings or transactions,
or proposed agreements, arrangements, understandings or transactions, between or
among the Company and any officer, director, or Principal Shareholder (as such

                  2. PURCHASE, SALE AND DELIVERY OF THE SECURITIES AND ADVISOR'S
WARRANTS.

                  (a) On the basis of the representations, warranties, covenants
and agreements herein contained, but subject to the terms and conditions herein
set forth, the Company agrees to sell to each Underwriter, and each Underwriter,
severally and not jointly, agrees to purchase from the Company at a price of
$______ per share of Common Stock, that number of Firm Shares set forth in
Schedule A opposite the name of such Underwriter, plus any additional number of
Firm Shares which such Underwriter may become obligated to purchase pursuant to
the provisions of SECTION 11 hereof.

                  (b) In addition, on the basis of the representations,
warranties, covenants and agreements herein contained, but subject to the terms
and conditions herein set forth, the Company hereby grants an option to the
Underwriters, severally and not jointly, to purchase all or any part of the
Option Shares. The option granted hereby will expire 30 days after (i) the date
the Registration Statement becomes effective, if the Company has elected not to
rely on Rule 430A under the Rules and Regulations, or (ii) the date of this
Agreement if the Company has elected to rely upon Rule 430A under the Rules and
Regulations, and may be exercised in whole or in part from time to time only for
the purpose of covering over-allotments which may be made in connection with the
offering and distribution of the Firm Shares upon notice by the Representative
to the Company setting forth the number of Option Shares as to which the several
Underwriters are then exercising the option and the time and date of payment and
delivery for any such Option Shares. Any such time and date of delivery (an
"Option Closing Date") shall be determined by the Representative, but shall not
be later than seven full business days after the exercise of said option, nor in
any event prior to the Closing Date, as hereinafter defined, unless otherwise
agreed upon by the Representative and the Company. Nothing herein contained
shall obligate the Underwriters to make any over-allotments. No Option Shares
shall be delivered unless the Firm Shares shall be simultaneously delivered or
shall theretofore have been delivered as herein provided.

                  (c) Payment of the purchase price for, and delivery of
certificates for, the Firm Shares shall be made at the offices of Josephthal
Lyon & Ross Incorporated at 200 Park Avenue, 24th Floor, New York, New York
10166, or at such other place as shall be agreed upon by the Representative and
the Company. Such delivery and payment shall be made at 10:00 a.m. (New York
City time) on _______________, 1997 or at such other time and date as shall be
agreed upon by the Representative and the Company, but not less than three (3)
nor more than seven (7) full business days after the effective date of the
Registration Statement (such time and date of payment and delivery being herein
called "Closing Date"). In addition, in the event that any or all of the Option
Shares are purchased by the Underwriters, payment of the purchase price for, and
delivery of certificates for, such Option Shares shall be made at the

                                      -11-
<PAGE>


above mentioned office of the Representative or at such other place as shall be
agreed upon by the Representative and the Company on each Option Closing Date
as specified in the notice from the Representative to the Company. Delivery of
the certificates for the Firm Shares and the Option Shares, if any, shall be
made to the Underwriters against payment by the Underwriters, severally and not
jointly, of the purchase price for the Firm Shares and the Option Shares, if
any, to the order of the Company for the Firm Shares and the Option Shares, if
any, by New York Clearing House funds. In the event such option is exercised,
each of the Underwriters, acting severally and not jointly, shall purchase that
proportion of the total number of Option Shares then being purchased which the
number of Firm Shares set forth in Schedule A hereto opposite the name of such
Underwriter bears to the total number of Firm Shares, subject in each case to
such adjustments as the Representative in its discretion shall make to
eliminate any sales or purchases of fractional shares. Certificates for the Firm
Shares and the Option Shares, if any, shall be in definitive, fully registered
form, shall bear no restrictive legends and shall be in such denominations and
registered in such names as the Underwriters may request in writing at least two
(2) business days prior to the Closing Date or the relevant Option Closing Date,
as the case may be. The certificates for the Firm Shares and the Option Shares,
if any, shall be made available to the Representative at such office or such
other place as the Representative may designate for inspection, checking and
packaging no later than 9:30 a.m. on the last business day prior to Closing Date
or the relevant Option Closing Date, as the case may be.

                  (d) On the Closing Date, the Company shall issue and sell to
Josephthal, Advisor's Warrants at a purchase price of $.0001 per warrant, which
warrants shall entitle the holders thereof to purchase an aggregate of 200,000
shares of Common Stock. The Advisor's Warrants shall be exercisable for a period
of four years commencing one year from the effective date of the Registration
Statement at a price equaling one hundred twenty percent (120%) of the initial
public offering price of the shares of Common Stock. The Advisor's Warrant
Agreement and form of Warrant Certificate shall be substantially in the form
filed as Exhibit 4.2 to the Registration Statement. Payment for the Advisor's
Warrants shall be made on the Closing Date.

                  3. PUBLIC OFFERING OF THE SHARES. As soon after the
Registration Statement becomes effective as the Representative deems advisable,
the Underwriters shall make a public offering of the Shares (other than to
residents of or in any jurisdiction in which qualification of the Shares is
required and has not become effective) at the price and upon the other terms set
forth in the Prospectus. The Representative may from time to time increase or
decrease the public offering price after distribution of the Shares has been
completed to such extent as the Representative, in its discretion deems
advisable. The Underwriters may enter into one of more agreements as the
Underwriters, in each of their sole discretion, deem advisable with one or more
broker-dealers who shall act as dealers in connection with such public offering.

                  4.       COVENANTS AND AGREEMENTS OF THE COMPANY.

                  (a) The Company covenants and agrees with each of the
Underwriters as follows:

                                    i) The Company shall use its best efforts to
                  cause the Registration Statement and any amendments thereto to
                  become effective as promptly as practicable and will not at
                  any time, whether before or after the effective date of the
                  Registration Statement, file any amendment to the Registration
                  Statement or supplement to the Prospectus or file any document
                  under the Act or Exchange Act before termination of the
                  offering of the Shares by the Underwriters of which the
                  Representative shall not previously have been advised and
                  furnished with a copy, or to which the Representative shall
                  have objected or which is not in compliance with the Act, the
                  Exchange Act or the Rules and Regulations.

                                    ii) As soon as the Company is advised or
                  obtains knowledge thereof, the Company will advise the
                  Representative and confirm the notice in writing, (i) when
                  the Registration Statement, as amended, becomes effective, if
                  the provisions of Rule 430A promulgated under the Act will be
                  relied upon, when the Prospectus has been filed in accordance
                  with said Rule 430A and when any post-effective amendment to
                  the Registration Statement becomes effective, (ii) of the
                  issuance by the Commission of any stop order or of the
                  initiation, or the threatening, of any proceeding, suspending
                  the effectiveness of the Registration Statement or any order
                  preventing or suspending the use of the Preliminary Prospectus
                  or the Prospectus, or any amendment or supplement thereto, or
                  the institution of proceedings for that purpose, (iii) of the
                  issuance by the Commission or by any state securities
                  commission of any proceedings for the suspension of the
                  qualification of any of the Securities for offering or sale in
                  any jurisdiction or of the initiation, or the threatening, of
                  any proceeding for that purpose, (iv) of the receipt of any
                  comments from the Commission; and (v) of any request by the
                  Commission for any amendment to the Registration Statement or
                  any amendment or supplement to the Prospectus or for
                  additional information. If the Commission or any state
                  securities commission authority shall enter a stop order or
                  suspend such qualification at any time, the Company will make
                  every effort to obtain promptly the lifting of such order.

                                    iii) The Company shall file the Prospectus
                  (in form and substance satisfactory to the Representative) or
                  transmit the Prospectus by a means reasonably calculated to
                  result in filing with the Commission pursuant to Rule
                  424(b)(1) (or, if applicable and if consented to by the
                  Representative, pursuant to Rule 424(b)(4)) not later than
                  the Commission's close of business on the earlier of (i) the
                  second business day following the execution and delivery of
                  this Agreement and (ii) the fifteenth business day after the
                  effective date of the Registration Statement.

                                    iv) The Company will give the
                  Representative notice of its intention to file or prepare any
                  amendment to the Registration Statement (including any
                  post-effective amendment) or any amendment or supplement to
                  the Prospectus (including any revised prospectus which the
                  Company proposes for use by the Underwriters in connection
                  with the offering of the Securities which differs from the
                  corresponding prospectus on file at the Commission at the time
                  the Registration Statement becomes effective, whether or not
                  such revised prospectus is required to be filed pursuant to
                  Rule 424(b) of the Rules and Regulations), and will furnish
                  the Representative with copies of any such amendment or
                  supplement a reasonable amount of time prior to such proposed
                  filing or use, as the case may be, and will not file any such
                  prospectus to which the Representative or Orrick, Herrington
                  & Sutcliffe LLP ("Underwriters' Counsel"), shall object.

                                    v) The Company shall endeavor in good faith,
                  in cooperation with the Representative, at or prior to the
                  time the Registration Statement becomes effective, to qualify
                  the Securities for offering and sale under the securities laws
                  of such jurisdictions as the Representative may designate to
                  permit the continuance of sales and dealings therein for as
                  long as may be necessary to complete the distribution, and
                  shall make such applications, file such documents and furnish
                  such information as may be required for such purpose;
                  PROVIDED, HOWEVER, the Company shall not be required to
                  qualify as a foreign corporation or file a general or limited
                  consent to service of process in any such jurisdiction. In
                  each jurisdiction where such qualification shall be effected,
                  the Company will, unless the Representative agrees that such
                  action is not at the time necessary or advisable, use all
                  reasonable efforts to file and make such statements or reports
                  at such times as are or may reasonably be required by the laws
                  of such jurisdiction to continue such qualification.

                                    vi) During the time when a prospectus is
                  required to be delivered under the Act, the Company shall use
                  all reasonable efforts to comply with all requirements imposed
                  upon it by the Act and the Exchange Act, as now and hereafter
                  amended and by the Rules and Regulations, as from time to time
                  in force, so far as necessary to permit the continuance of
                  sales of or dealings in the Securities in accordance with the
                  provisions hereof and the Prospectus, or any amendments or
                  supplements thereto. If at any time when a prospectus relating
                  to the Securities is required to be delivered under the Act,
                  any event shall have occurred as a result of which, in the
                  opinion of counsel for the Company or Underwriters' Counsel,
                  the Prospectus, as then amended or supplemented, includes an
                  untrue statement of a material fact or omits to state any
                  material fact required to be stated therein or necessary to
                  make the statements therein, in the light of the circumstances
                  under which they were made, not misleading, or if it is
                  necessary at any time to amend the Prospectus to comply with
                  the Act, the Company will notify the Representative promptly
                  and prepare and file with the Commission an appropriate
                  amendment or supplement in accordance with SECTION 10 of the
                  Act, each such amendment or supplement to be satisfactory to

                                      -14-
<PAGE>

                  Underwriters' Counsel, and the Company will furnish to the
                  Underwriters copies of such amendment or supplement as soon as
                  available and in such quantities as the Underwriters may
                  request.

                                    vii) As soon as practicable, but in any
                  event not later than 45 days after the end of the 12-month
                  period beginning on the day after the end of the fiscal
                  quarter of the Company during which the effective date of the
                  Registration Statement occurs (90 days in the event that the
                  end of such fiscal quarter is the end of the Company's fiscal
                  year), the Company shall make generally available to its
                  security holders, in the manner specified in Rule 158(b) of
                  the Rules and Regulations, and to the Representative, an
                  earnings statement which will be in the detail required by,
                  and will otherwise comply with, the provisions of SECTION
                  11(a) of the Act and Rule 158(a) of the Rules and Regulations,
                  which statement need not be audited unless required by the
                  Act, covering a period of at least 12 consecutive months after
                  the effective date of the Registration Statement.

                                    viii) During a period of seven years after
                  the date hereof, the Company will furnish to its stockholders
                  annual reports (including financial statements audited by
                  independent public accountants) and will deliver to the
                  Representative:

                                            (a) concurrently with furnishing
                           such quarterly reports to its stockholders,
                           statements of income of the Company for each quarter
                           in the form furnished to the Company's stockholders
                           and certified by the Company's principal financial or
                           accounting officer;

                                            (b) concurrently with furnishing
                           such annual reports to its stockholders, a balance
                           sheet of the Company as at the end of the preceding
                           fiscal year, together with statements of operations,
                           stockholders' equity, and cash flows of the Company
                           for such fiscal year, accompanied by a copy of the
                           report thereon of independent certified public

                                            (c)      as soon as they are 
                           available, copies of all reports (financial or 
                           other) mailed to stockholders;

                                            (d)      as soon as they are 
                           available, copies of all reports and financial 
                           statements furnished to or filed with the 
                           Commission, the NASD or any securities exchange;

                                            (e) every press release and every

                                            (f)      any additional information
                           of a public nature concerning the Company (and any 
                           future subsidiary) or its businesses which the 
                           Representative may request.

                                    During such five (5)-year period, if the
                  Company has an active subsidiary, the foregoing financial
                  statements will be on a consolidated basis to the extent that
                  the accounts of the Company and its subsidiary are
                  consolidated, and will be accompanied by similar financial
                  statements for any significant subsidiary which is not so

                  Agent and, if necessary under the jurisdiction of
                  incorporation of the Company, a Registrar (which may be the
                  same entity as the Transfer Agent) for its Common Stock.

                                    x) The Company will furnish to the
                  Representative or on the Representative's order, without

statement of fact which, in the Representative's opinion, is material, or omits
to state a fact which, in the Representative's opinion, is material and is

misleading, or that the Prospectus, or any supplement thereto, contains an
untrue statement of fact which, in the Representative's opinion, is material, or
omits to state a fact which, in the Representative's opinion, is material and is
required to be stated therein or is necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading.

                  (c) On or prior to the Closing Date, the Representative shall
have received from Underwriters' Counsel, such opinion or opinions with respect
to the organization of the Company, the validity of the Securities, the
Advisor's Warrants, the Registration Statement, the Prospectus and other related
matters as the Representative requests and Underwriters' Counsel shall have

such matters.

                  (d) At Closing Date, the Underwriters shall have received the
favorable opinion of Broad and Cassel, counsel to the Company, dated the Closing
Date, addressed to the Underwriters and in form and substance satisfactory to
Underwriters' Counsel, to the effect that:

                           i) the Company (A) has been duly organized and is
                  validly existing as a corporation in good standing under the
                  laws of its jurisdiction, (B) is duly qualified and licensed
                  and in good standing as a foreign corporation in each
                  jurisdiction in which its ownership or leasing of any
                  properties or the character of its operations requires such
                  qualification or licensing, and (C) has all requisite

                                      -20-
<PAGE>

                  corporate power and authority; and the Company has obtained
                  any and all necessary authorizations, approvals, orders,
                  licenses, certificates, franchises and permits of and from all
                  governmental or regulatory officials and bodies (including,
                  without limitation, those having jurisdiction over
                  environmental or similar matters), to own or lease its
                  properties and conduct its business as described in the
                  Prospectus; the Company is and has been doing business in
                  material compliance with all such authorizations, approvals,
                  orders, licenses, certificates, franchises and permits and all
                  federal, state and local laws, rules and regulations; the
                  Company has not received any notice of proceedings relating to
                  the revocation or modification of any such authorization,
                  approval, order, license, certificate, franchise, or permit
                  which, singly or in the aggregate, if the subject of an
                  unfavorable decision, ruling or finding, would materially
                  adversely affect the business, operations, condition,
                  financial or otherwise, or the earnings, business affairs,
                  position, prospects, value, operation, properties, business or
                  results of operations of the Company. The disclosures in the
                  Registration Statement concerning the effects of federal,
                  state and local laws, rules and regulations on the Company's
                  business as currently conducted and as contemplated are
                  correct in all material respects and do not omit to state a
                  fact necessary to make the statements contained therein not
                  misleading in light of the circumstances in which they were
                  made;

                           ii) to the best of such counsel's knowledge, the
                  Company does not own an interest in any other corporation,
                  partnership, joint venture, trust or other business entity;

                           iii) the Company has a duly authorized, issued and
                  outstanding capitalization as set forth in the Prospectus, and
                  any amendment or supplement thereto, under "Capitalization"
                  and "Description of Capital Stock," and is not a party to or
                  bound by any instrument, agreement or other arrangement
                  providing for it to issue any capital stock, rights, warrants,
                  options or other securities, except for this Agreement, the
                  Advisor's Warrant Agreement and as described in the
                  Prospectus. The Securities, and all other securities issued or
                  issuable by the Company conform in all material respects to
                  all statements with respect thereto contained in the
                  Registration Statement and the Prospectus. All issued and
                  outstanding securities of the Company have been duly
                  authorized and validly issued and are fully paid and
                  non-assessable; the holders thereof have no rights of
                  rescission with respect thereto, and are not subject to
                  personal liability by reason of being such holders; and none
                  of such securities were issued in violation of the preemptive
                  rights of any holders of any security of the Company. The
                  Shares, the Advisor's Warrants and the Advisor's Shares to be
                  sold by the Company hereunder and under the Advisor's Warrant
                  Agreement are not and will not be subject to any preemptive or
                  other similar rights of any stockholder, have been duly
                  authorized and, when issued, paid for and delivered in
                  accordance with the terms hereof, will be validly issued,
                  fully paid and non-assessable and conform to the description
                  thereof contained in the Prospectus; the holders thereof will
                  not be subject to any liability solely as such holders; all

although such counsel is not passing upon and does not assume any responsibility
for the accuracy, completeness or fairness of the statements contained in the
Preliminary Prospectus, the Registration Statement and Prospectus, on the basis
of the foregoing, no facts have come to the attention of such counsel which lead
them to believe that either the Registration Statement or any amendment thereto,
at the time such Registration Statement or amendment became effective or the
Preliminary Prospectus or Prospectus or amendment or supplement thereto as of
the date of such opinion contained any untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary to
make the statements therein not misleading (it being understood that such
counsel need express no opinion with respect to the financial statements and
schedules and other financial and statistical data included in the Preliminary
Prospectus, the Registration Statement or Prospectus).

qualified by, or that it is otherwise subject to, any treatise, written policy
or other document relating to legal opinions, including, without limitation, the
Legal Opinion Accord of the ABA Section of Business Law (1991), or any
comparable State bar accord.

                  In rendering such opinion, such counsel may rely (A) as to
matters involving the application of laws other than the laws of the United
States and jurisdictions in which they are admitted, to the extent such counsel
deems proper and to the extent specified in such opinion, if at all, upon an
opinion or opinions (in form and substance satisfactory to Underwriters'
Counsel) of other counsel acceptable to Underwriters' Counsel, familiar with the
applicable laws; (B) as to matters of fact, to the extent they deem proper, on
certificates and written statements of responsible officers of the Company, and
certificates or other written statements of officers of departments of various
jurisdictions having custody of documents respecting the corporate existence or
good standing of the Company, provided that copies of any such statements or
certificates shall be delivered to Underwriters' Counsel if requested. The
opinion of such counsel for the Company shall state that the opinion of any such
other counsel is in form satisfactory to such counsel and that the
Representative and they are justified in relying thereon. Such opinion shall
also state that Underwriters' Counsel is entitled to rely thereon.

                  (e) At each Option Closing Date, if any, the Underwriters
shall have received the favorable opinion of Broad and Cassel, counsel to the
Company, dated the Option Closing Date, addressed to the Underwriters and in
form and substance satisfactory to Underwriters' Counsel confirming as of the
Option Closing Date the statements made by Broad and Cassel in its opinion
delivered on the Closing Date.

                  (f) On or prior to each of the Closing Date and the Option
Closing Date, if any, Underwriters' Counsel shall have been furnished such
documents, certificates and opinions as they may reasonably require for the
purpose of enabling them to review or pass upon the matters referred to in
subsection (c) of this SECTION 6, or in order to evidence the accuracy,
completeness or satisfaction of any of the representations, warranties or
conditions of the Company, or herein contained.

otherwise, prospects, stockholders' equity or the business activities of the
Company, whether or not in the ordinary course of business, from the latest

by the principal executive officer and by the chief financial or chief
accounting officer of the Company, dated the Closing Date or Option Closing

examined the Registration Statement, the Prospectus and this Agreement, and
that:

                           i) The representations and warranties of the Company
                  in this Agreement are true and correct as if made on and as of

                  covenants and satisfied all conditions contained in this
                  Agreement on its part to be performed or satisfied at or prior
                  to such Closing Date or Option Closing Date, as the case may
                  be;

                           ii) No stop order suspending the effectiveness of the
                  Registration Statement or any part thereof has been issued,
                  and no proceedings for that purpose have been instituted or

                  or necessary to make the statements therein not misleading and

                  circumstances under which they were made, not misleading; and

                           iv) Subsequent to the respective dates as of which

                  to same) against the Company, or any affiliated party of any
                  of the foregoing which is required to be set forth in an
                  amended or supplemented Prospectus which has not been set
                  forth; and (h) there has occurred no event required to be set
                  forth in an amended or supplemented Prospectus which has not

changes or decreases, if any, referred to in clause (iii) below) in all respects
to the Underwriters and Underwriters' Counsel, from Deloitte:

                           i) confirming that they are independent public
                  accountants with respect to the Company within the meaning of
                  the Act and the applicable Rules and Regulations;

                           ii) stating that it is their opinion that the
                  financial statements and supporting schedules of the Company
                  included in the Registration Statement comply as to form in
                  all material respects with the applicable accounting

                                      -28-
<PAGE>


                  requirements of the Act and the Rules and Regulations
                  thereunder and that the Representative may rely upon the
                  opinion of Deloitte with respect to such financial statements
                  and supporting schedules included in the Registration
                  Statement;

                           iii) stating that, on the basis of a limited review
                  which included a reading of the latest available unaudited
                  interim financial statements of the Company, a reading of the
                  latest available minutes of the stockholders and board of
                  directors and the various committees of the board of directors
                  of the Company, consultations with officers and other
                  employees of the Company responsible for financial and
                  accounting matters and other specified procedures and
                  inquiries, nothing has come to their attention which would
                  lead them to believe that (A) the unaudited financial
                  statements and supporting schedules of the Company included in
                  the Registration Statement do not comply as to form in all
                  material respects with the applicable accounting requirements
                  of the Act and the Rules and Regulations or are not fairly
                  presented in conformity with generally accepted accounting
                  principles applied on a basis substantially consistent with
                  that of the audited financial statements of the Company
                  included in the Registration Statement, or (B) at a specified
                  date not more than five (5) days prior to the effective date
                  of the Registration Statement, there has been any change in
                  the capital stock of the Company, any change in the long-term
                  debt of the Company, or any decrease in the stockholders'
                  equity of the Company or any decrease in the net current
                  assets or net assets of the Company as compared with amounts
                  shown in the December 31, 1996 balance sheet included in the
                  Registration Statement, other than as set forth in or
                  contemplated by the Registration Statement, or, if there was
                  any change or decrease, setting forth the amount of such
                  change or decrease, and (C) during the period from December
                  31, 1996 to a specified date not more than five (5) days prior
                  to the effective date of the Registration Statement, there was
                  any decrease in net revenues or net earnings of the Company or
                  increase in net earnings per common share of the Company, in
                  each case as compared with the corresponding period beginning
                  December 31, 1995 other than as set forth in or contemplated
                  by the Registration Statement, or, if there was any such
                  decrease, setting forth the amount of such decrease;

                           iv) setting forth, at a date not later than five (5)
                  days prior to the date of the Registration Statement, the
                  amount of liabilities of the Company (including a break-down
                  of commercial paper and notes payable to the banks);

                           v) stating that they have compared specific dollar
                  amounts, numbers of shares, percentages of revenues and
                  earnings, statements and other financial information
                  pertaining to the Company set forth in the Prospectus in each
                  case to the extent that such amounts, numbers, percentages,
                  statements and information may be derived from the general
                  accounting records, including work sheets, of the Company and
                  excluding any questions requiring an interpretation by legal
                  counsel, with the results obtained from the application of
                  specified readings, inquiries and other appropriate procedures
                  (which procedures do not constitute an

                                      -29-
<PAGE>


                  examination in accordance with generally accepted auditing 
                  standards) set forth in the letter and found them to be in 
                  agreement; and

                           vi) statements as to such other matters incident to
                  the transaction contemplated hereby as the Representative may

                  (n) No order suspending the sale of the Securities in any

                  7.       INDEMNIFICATION.

                  (a) The Company agrees to indemnify and hold harmless each of
the Underwriters (for purposes of this SECTION 7 "Underwriter" shall include the
officers, directors, partners, employees, agents and counsel of the Underwriter,
including specifically each person who may be substituted for an Underwriter as
provided in SECTION 11 hereof), and each person, if any, who controls the
Underwriter ("controlling person") within the meaning of Section 15 of the Act
or Section 20(a) of the Exchange Act, from and against any and all losses,
claims, damages, expenses or liabilities, joint or several (and actions,
proceedings, investigations, inquiries, and suits in respect thereof),
whatsoever (including but not limited to any and all costs and expenses
whatsoever reasonably incurred in investigating, preparing or defending against
such action, proceeding, investigation, inquiry or suit, commenced or
threatened, or any claim whatsoever), as such are incurred, to which the
Underwriter or such controlling person may become subject under the Act, the
Exchange Act or any other statute or at common law or otherwise or under the
laws of foreign countries, arising out of or based upon (A) any untrue statement
or alleged untrue statement of a material fact contained (i) in any Preliminary
Prospectus, the Registration Statement or the Prospectus (as from time to time
amended and supplemented); (ii) in any post-effective amendment or amendments or
any new registration statement and prospectus in which is included securities of
the Company issued or issuable upon exercise of the Securities; or (iii) in any
application or other document or written communication (in this SECTION 7
collectively called "application") executed by the Company or based upon written
information furnished by the Company filed, delivered or used in any
jurisdiction in order to qualify the Securities under the securities laws
thereof or filed with the Commission, any state securities commission or agency,
Nasdaq or any other securities exchange, (B) the omission or alleged omission
therefrom of a material fact required to be stated therein or necessary to make
the statements therein not misleading (in the case of the Prospectus, in the
light of the circumstances under which they were made), or (C) any breach of any


                                      -31-
<PAGE>

representation, warranty, covenant or agreement of the Company contained herein
or in any certificate by or on behalf of the Company or any of its officers
delivered pursuant hereto unless, in the case of clause (A) or (B) above, such
statement or omission was made in reliance upon and in conformity with written
information furnished to the Company with respect to any Underwriter by or on
behalf of such Underwriter expressly for use in any Preliminary Prospectus, the
Registration Statement or any Prospectus, or any amendment thereof or supplement
thereto, or in any application, as the case may be.

                  The indemnity agreement in this subsection (a) shall be in
addition to any liability which the Company may have at common law or otherwise.

                  (b) Each of the Underwriters agrees severally, but not
jointly, to indemnify and hold harmless the Company, each of its directors, each
of its officers who has signed the Registration Statement, and each other
person, if any, who controls the Company within the meaning of the Act, to the
same extent as the foregoing indemnity from the Company to the Underwriters but
only with respect to statements or omissions, if any, made in any Preliminary
Prospectus, the Registration Statement or Prospectus or any amendment thereof or
supplement thereto or in any application made in reliance upon, and in strict
conformity with, written information furnished to the Company with respect to
any Underwriter by such Underwriter expressly for use in such Preliminary
Prospectus, the Registration Statement or Prospectus or any amendment thereof or
supplement thereto or in any such application, provided that such written
information or omissions only pertain to disclosures in the Preliminary
Prospectus, the Registration Statement or Prospectus directly relating to the
transactions effected by the Underwriters in connection with this Offering. The
Company acknowledges that the statements with respect to the public offering of
the Securities set forth under the heading "Underwriting" and the stabilization
legend in the Prospectus have been furnished by the Underwriters expressly for
use therein and constitute the only information furnished in writing by or on
behalf of the Underwriters for inclusion in the Prospectus.

                  The indemnity agreement in this subsection (b) shall be in
addition to any liability which the Underwriters may have at common law or
otherwise.

                  (c) Promptly after receipt by an indemnified party under this
SECTION 7 of notice of the commencement of any action, suit or proceeding, such
indemnified party shall, if a claim in respect thereof is to be made against one
or more indemnifying parties under this SECTION 7, notify each party against
whom indemnification is to be sought in writing of the commencement thereof (but
the failure so to notify an indemnifying party shall not relieve it from any
liability which it may have under this SECTION 7 except to the extent that it
has been prejudiced in any material respect by such failure or from any
liability which it may have otherwise). In case any such action, investigation,
inquiry, suit or proceeding is brought against any indemnified party, and it
notifies an indemnifying party or parties of the commencement thereof, the
indemnifying party or parties will be entitled to participate therein, and to
the extent it may elect by written notice delivered to the indemnified party
promptly after receiving the aforesaid notice from such indemnified party, to
assume the defense thereof with counsel reasonably satisfactory to such
indemnified party. Notwithstanding the foregoing, the indemnified party or
parties shall have the right to employ its or their own counsel in any such

                                      -32-
<PAGE>


case but the fees and expenses of such counsel shall be at the expense of such
indemnified party or parties unless (i) the employment of such counsel shall
have been authorized in writing by the indemnifying parties in connection with
the defense of such action at the expense of the indemnifying party, (ii) the
indemnifying parties shall not have employed counsel reasonably satisfactory to
such indemnified party to have charge of the defense of such action within a
reasonable time after notice of commencement of the action, or (iii) such
indemnified party or parties shall have reasonably concluded that there may be
defenses available to it or them which are different from or additional to those
available to one or all of the indemnifying parties (in which case the
indemnifying parties shall not have the right to direct the defense of such
action, investigation, inquiry, suit or proceeding on behalf of the indemnified
party or parties), in any of which events such fees and expenses of one
additional counsel shall be borne by the indemnifying parties. In no event shall
the indemnifying parties be liable for fees and expenses of more than one
counsel (in addition to any local counsel) separate from their own counsel for
all indemnified parties in connection with any one action, investigation,
inquiry, suit or proceeding or separate but similar or related actions,
investigations, inquiries, suits or proceedings in the same jurisdiction arising
out of the same general allegations or circumstances. Anything in this SECTION 7
to the contrary notwithstanding, an indemnifying party shall not be liable for
any settlement of any claim or action effected without its written consent;
PROVIDED, HOWEVER, that such consent was not unreasonably withheld. An
indemnifying party will not, without the prior written consent of the
indemnified parties, settle compromise or consent to the entry of any judgment
with respect to any pending or threatened claim, action, investigation, inquiry,
suit or proceeding in respect of which indemnification or contribution may be
sought hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action), unless such settlement, compromise or consent
(i) includes an unconditional release of each indemnified party form all
liability arising out of such claim, action, suit or proceeding and (ii) does
not include a statement as to or an admission of fault, culpability or a failure
to act by or on behalf of any indemnified party.

                  (d) In order to provide for just and equitable contribution in
any case in which (i) an indemnified party makes claim for indemnification
pursuant to this SECTION 7, but it is judicially determined (by the entry of a
final judgment or decree by a court of competent jurisdiction and the expiration
of time to appeal or the denial of the last right of appeal) that such
indemnification may not be enforced in such case notwithstanding the fact that
the express provisions of this SECTION 7 provide for indemnification in such
case, or (ii) contribution under the Act may be required on the part of any
indemnified party, then each indemnifying party shall contribute to the amount
paid as a result of such losses, claims, damages, expenses or liabilities (or
actions, investigations, inquiries, suits or proceedings in respect thereof) (A)
in such proportion as is appropriate to reflect the relative benefits received
by each of the contributing parties, on the one hand, and the party to be
indemnified on the other hand, from the offering of the Securities or (B) if the
allocation provided by clause (A) above is not permitted by applicable law, in
such proportion as is appropriate to reflect not only the relative benefits
referred to in clause (i) above but also the relative fault of each of the
contributing parties, on the one hand, and the party to be indemnified on the
other hand in connection with the statements or omissions that resulted in such
losses, claims, damages, expenses or liabilities, as well as any other relevant
equitable considerations. In any case where the Company is the contributing
party and the Underwriters are the indemnified party, the relative benefits
received

                                      -33-
<PAGE>


by the Company, on the one hand, and the Underwriters, on the other, shall be
deemed to be in the same proportion as the total net proceeds from the offering
of the Securities (before deducting expenses) bear to the total underwriting
discounts received by the Underwriters hereunder, in each case as set forth in
the table on the Cover Page of the Prospectus. Relative fault shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company, or by the
Underwriters, and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such untrue statement or omission. The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages, expenses or liabilities (or actions, investigations, inquiries,
suits or proceedings in respect thereof) referred to above in this subdivision
(d) shall be deemed to include any legal or other expenses reasonably incurred
by such indemnified party in connection with investigating or defending any such
action, claim, investigation, inquiry, suit or proceeding. Notwithstanding the
provisions of this subdivision (d) the Underwriters shall not be required to
contribute any amount in excess of the underwriting discount applicable to the
Securities purchased by the Underwriters hereunder. No person guilty of
fraudulent misrepresentation (within the meaning of SECTION 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. For purposes of this SECTION 7, each person, if
any, who controls the Company within the meaning of the Act, each officer of the
Company who has signed the Registration Statement, and each director of the
Company shall have the same rights to contribution as the Company, subject in
each case to this subparagraph (d). Any party entitled to contribution will,
promptly after receipt of notice of commencement of any action, suit, inquiry,
investigation or proceeding against such party in respect to which a claim for
contribution may be made against another party or parties under this
subparagraph (d), notify such party or parties from whom contribution may be
sought, but the omission so to notify such party or parties shall not relieve
the party or parties from whom contribution may be sought from any obligation it
or they may have hereunder or otherwise than under this subparagraph (d), or to
the extent that such party or parties were not adversely affected by such
omission. The contribution agreement set forth above shall be in addition to any
liabilities which any indemnifying party may have at common law or otherwise.

                  8. REPRESENTATIONS AND AGREEMENTS TO SURVIVE DELIVERY. All
representations, warranties and agreements contained in this Agreement or
contained in certificates of officers of the Company submitted pursuant hereto,
shall be deemed to be representations, warranties and agreements at the Closing
Date and the Option Closing Date, as the case may be, and such representations,
warranties and agreements of the Company and the indemnity agreements contained
in SECTION 7 hereof, shall remain operative and in full force and effect
regardless of any investigation made by or on behalf of any Underwriter, the
Company, any controlling person of any Underwriter, the Company, and shall
survive termination of this Agreement or the issuance, sale and delivery of the
Securities to the Underwriters and the Representative, as the case may be.

                  9.       EFFECTIVE DATE.

                  (a) This Agreement shall become effective at 10:00 a.m., New
York City time, on the next full business day following the date hereof, or at
such earlier time after the

                                      -34-
<PAGE>


Registration Statement becomes effective as the Representative, in their
discretion, shall release the Securities for sale to the public; PROVIDED,
HOWEVER, that the provisions of SECTIONS 5, 7 and 10 of this Agreement shall at
all times be effective. For purposes of this SECTION 9, the Shares to be
purchased hereunder shall be deemed to have been so released upon the earlier of
dispatch by the Representatives of telegrams to securities dealers releasing
such shares for offering or the release by the Representative for publication
of the first newspaper advertisement which is subsequently published relating to
the Shares.

                  10.      TERMINATION.

                  (a) Subject to subsection (b) of this SECTION 10, the
Representative shall have the right to terminate this Agreement, after the date
hereof, (i) if any domestic or international event or act or occurrence has
materially disrupted, or in the Representative's opinion will in the immediate
future materially adversely disrupt the financial markets; or (ii) any material
adverse change in the financial markets shall have occurred; or (iii) if trading
generally shall have been suspended or materially limited on or by, as the case
may be, any of the New York Stock Exchange, the American Stock Exchange, the
National Association of Securities Dealers, Inc., the Boston Stock Exchange, the
Commission or any other government authority having jurisdiction; or (iv) if
trading of any of the securities of the Company shall have been suspended, or
any of the securities of the Company shall have been delisted, on any exchange
or in any over-the-counter market; or (v) if the United States shall have become
involved in a war or major hostilities, or if there shall have been an
escalation in an existing war or major hostilities or a national emergency shall
have been declared in the United States; or (vi) if a banking moratorium has
been declared by a state or federal authority; or (vii) if a moratorium in
foreign exchange trading has been declared; or (viii) if the Company shall have
sustained a loss material or substantial to the Company by fire, flood,
accident, hurricane, earthquake, theft, sabotage or other calamity or malicious
act which, whether or not such loss shall have been insured, will, in the
Representative's opinion, make it inadvisable to proceed with the delivery of
the Securities; or (viii) if there shall have occurred any outbreak or
escalation of hostilities or any calamity or crisis or there shall have been
such a material adverse change in the conditions or prospects of the Company, or
such material adverse change in the general market, political or economic
conditions, in the United States or elsewhere as in the Representative's
judgment would make it inadvisable to proceed with the offering, sale and/or
delivery of the Securities or (ix) if Stephen R. Cohen, Robert Kennedy and Shane
D. Mattaway shall no longer serve the Company in their present capacity.

                  (b) If this Agreement is terminated by the Representative in
accordance with the provisions of SECTION 10(a) the Company shall promptly
reimburse and indemnify the Representative for all of its actual out-of-pocket
expenses, including the fees and disbursements of counsel for the Underwriters
(less amounts previously paid pursuant to SECTION 5(c) above). Notwithstanding
any contrary provision contained in this Agreement, if this Agreement shall not
be carried out within the time specified herein, or any extension thereof
granted to the Representative, by reason of any failure on the part of the
Company to perform any undertaking or satisfy any condition of this Agreement by
it to be performed or satisfied (including, without limitation, pursuant to
SECTION 6 or SECTION 12) then, the Company shall promptly reimburse and
indemnify the Representative for all of its actual out-of-pocket

                                      -35-
<PAGE>

expenses, including the fees and disbursements of counsel for the Underwriters
(less amounts previously paid pursuant to SECTION 5(c) above). In addition, the
Company shall remain liable for all Blue Sky counsel fees and expenses and
filing fees. Notwithstanding any contrary provision contained in this Agreement,
any election hereunder or any termination of this Agreement (including, without
limitation, pursuant to SECTIONS 6, 10, 11 and 12 hereof), and whether or not
this Agreement is otherwise carried out, the provisions of SECTION 5 and SECTION
7 shall not be in any way affected by such election or termination or failure to
carry out the terms of this Agreement or any part hereof.

                  11. SUBSTITUTION OF THE UNDERWRITERS. If one or more of the
Underwriters shall fail (otherwise than for a reason sufficient to justify the
termination of this Agreement under the provisions of SECTION 6, SECTION 10 or
SECTION 12 hereof) to purchase the Securities which it or they are obligated to
purchase on such date under this Agreement (the "Defaulted Securities"), the
Representative shall have the right, within 24 hours thereafter, to make
arrangement for one or more of the non-defaulting Underwriters, or any other
underwriters, to purchase all, but not less than all, of the Defaulted
Securities in such amounts as may be agreed upon and upon the terms herein set
forth; if, however, the Representative shall not have completed such
arrangements within such 24-hour period, then:

                           (a) if the number of Defaulted Securities does not
                  exceed 10% of the total number of Firm Shares to be purchased
                  on such date, the non-defaulting Underwriters shall be
                  obligated to purchase the full amount thereof in the
                  proportions that their respective underwriting obligations
                  hereunder bear to the underwriting obligations of all
                  non-defaulting Underwriters, or

                           (b) if the number of Defaulted Securities exceeds 10%
                  of the total number of Firm Shares, this Agreement shall
                  terminate without liability on the part of any non-defaulting
                  Underwriters.

                  No action taken pursuant to this SECTION shall relieve any
defaulting Underwriter from liability in respect of any default by such
Underwriter under this Agreement.

                  In the event of any such default which does not result in a
termination of this Agreement, the Representative shall have the right to
postpone the Closing Date for a period not exceeding seven days in order to
effect any required changes in the Registration Statement or Prospectus or in
any other documents or arrangements.

                  12. DEFAULT BY THE COMPANY. If the Company shall fail at the
Closing Date or at any Option Closing Date, as applicable, to sell and deliver
the number of Shares which it is obligated to sell hereunder on such date, then
this Agreement shall terminate (or, if such default shall occur with respect to
any Option Shares to be purchased on an Option Closing Date, the Underwriters
may at the Representative's option, by notice from the Representative to the
Company, terminate the Underwriters' obligation to purchase Option Shares from
the Company on such date) without any liability on the part of any
non-defaulting party other than pursuant to SECTION 5, SECTION 7 and SECTION 10
hereof. No action taken pursuant to this SECTION shall relieve the Company from
liability, if any, in respect of such default.

                  Re: Public Offering of NetSpeak Corporation

Gentlemen:

We have acted as special counsel to NETSPEAK CORPORATION, a Florida corporation

certain Underwriting Agreement by and between Josephthal, Lyon & Ross
Incorporated ("Josephthal"), as representative of the several underwriters named
in Schedule A thereto, and the Company, dated _______________, 1997 (the
"Underwriting Agreement"). This opinion is provided to you pursuant to Section

                  permitting the Company's actual use of, the material licensed
                  or otherwise distributed by the Company and listed on Schedule
                  D annexed hereto and hereby incorporated by reference herein

                  (vi) an intellectual property litigation search with respect

                  marks, copyrights, service and trade names, intellectual
                  property licenses and other rights, and

<PAGE>



                  (b) the intellectual property general intangibles licensed to
                  the Company, including, without limitation, the patents,
                  patent applications, inventions, know how, trademarks, service
                  marks, copyrights, service and trade names and other
                  intellectual property rights licensed to the Company pursuant
                  to the Licenses (listed on Schedule C),

                  said search certified to us as complete and accurate by
                  ________________ and current through ________________________,
                  1996 (no earlier than 5 days prior to the date of the Closing)
                  and said jurisdictions being the only jurisdictions in which
                  filing of UCC financing statements or other documents may be
                  filed to effectively evidence a security or other interest in
                  said general intangibles; and

                  (viii) any and all records, documents, instruments and
                  agreements in our possession or under our control relating to
                  the Company.

                  We have also examined such corporate records, documents,
                  instruments and agreements, and inquired into such other
                  matters, as we have deemed necessary or appropriate as a basis
                  for the opinions set forth herein. Whenever our opinion herein
                  is qualified by the phrase "to the best of our knowledge" or
                  "to the best of our knowledge, after due inquiry," such
                  language means that, based upon (i) our inquiries of officers
                  of the Company, (ii) our review of the Documents, and (iii)
                  our review of such other corporate records, documents,
                  instruments and agreements described in the first sentence of
                  this paragraph, we believe that such opinions are factually
                  correct.

To the best of our knowledge, as to all matters of fact represented to you by
the Company, we advise you that nothing has come to our attention that would
cause us to believe that such facts are incorrect, incomplete or misleading or
that reliance thereon is not warranted under the circumstances. We call to your
attention that our opinion is limited to such facts as they exist on the date
hereof and do not take into account any change of circumstances, fact or law
subsequent thereto.

Based upon and subject to the foregoing, we are of the opinion that:

1. To the best of our knowledge, after due inquiry, except as described in the
Registration Statement, the Company owns or has the right to use, free and clear
of all liens, encumbrances, pledges, security interests, defects or other
restrictions or equities of any kind whatsoever,

<PAGE>




                  (i) all patents and patent applications (including, without
                  limitation, the Patents),

                  (ii) all trademarks and service marks (including, without
                  limitation, the Trademarks),

                  (iii) all copyrights (including, without limitation, the
                  Copyrighted Material),

                  (iv) all service and trade names,

                  (v) all intellectual property licenses (including, without
                  limitation, the Licenses), and

                  (vi) all technology used in, contemplated to be used in or 
required for, the conduct of the Company's business.

2. To the best of our knowledge, after due inquiry, the Company possesses all
material intellectual property licenses or rights used in, or required for, the
conduct of its business (including, the Licenses and without limitation, any
such licenses or rights described in the Registration Statement as being owned,
possessed or licensed by the Company, as the case may be), such licenses and
rights are in full force and effect, and the Company's products, methods and
services do not infringe any unlicensed intellectual property of any third
parties.

3. To the best of our knowledge, after due inquiry, there is no claim or action,
pending, threatened or potential, which affects or could affect the rights of
the Company with respect to any trademarks, service marks, copyrights, service
names, trade names, patents, patent applications or licenses used in, or
required for, the conduct of the Company's business and all trademarks, service
marks, copyrights, trade names, and patents owned or licensed to the Company are
valid.

4. To the best of our knowledge, after due inquiry, there is no intellectual
property based claim or action, pending, threatened or potential, which affects
or could affect the rights of the Company with respect to any products,
services, processes or licenses, including, without limitation, the Licenses
used in the conduct of the Company's business.

5. To the best of our knowledge, after due inquiry, except as described in the
Registration Statement, the Company is not under any obligation to pay royalties
or fees to any third party with respect to any material, technology or
intellectual properties developed, employed, licensed or used by the Company.

<PAGE>


6. To the best of our knowledge, after due inquiry, the statements in the
Registration Statement under the headings, "Risk Factors - Patents, Trademarks
and Proprietary Information" and "Business - Patents, Trademarks and Proprietary
Information", are accurate in all material respects, fairly represent the
information disclosed therein and do not omit to state any fact necessary to
make the statements made therein complete and accurate.

7. To the best of our knowledge, after due inquiry, the statements in the
Registration Statement and the Prospectus do not contain any untrue statement of
a material fact with respect to the intellectual property position of the
Company, or omit to state any material fact relating to the intellectual
property position of the Company which is required to be stated in the
Registration Statement and the Prospectus or is necessary to make the statements
therein not misleading.

We call your attention to the fact that the members of this firm are licensed to
practice law in the State of ______________ and before the United States Patent
and Trademark Office as Registered Patent Attorneys. Accordingly, we express no
opinion with respect to the laws, rules and regulations of any jurisdictions
other than the State of ___________ and the United States of America.

The opinions expressed herein are for the sole benefit of, and may be relied
upon only by, the several Underwriters named in Schedule A to the Underwriting
Agreement and Orrick, Herrington & Sutcliffe.

                                                  Very truly yours,
   
                                                                 EXHIBIT 3.1

waiver thereof in writing signed by the person or persons entitled to such
notice, whether signed before, during or after the time of the meeting stated
therein, and delivered to the Corporation for inclusion in the minutes or filing
with the corporate records, shall be equivalent to the giving of such notice.
Neither the business to be transacted at, nor the purpose of, any regular or
special meeting of the shareholders need be specified in any written waiver of
notice. Attendance of a person at a meeting shall constitute a waiver of (a)
lack of or defective notice of such meeting, unless the person objects at the
beginning to the holding of the meeting or the transacting of any business at
the meeting, or (b) lack of defective notice of a particular matter at a meeting
that is not within the purpose or purposes described in the meeting notice,
unless the person objects to considering such matter when it is presented.

         Section 6.  BUSINESS OF SPECIAL MEETING.  Business transacted at any 
special meeting shall be confined to the purposes stated in the notice thereof.

         Section 7. QUORUM. Shares entitled to vote as a separate voting group
may take action on a matter at a meeting only if a quorum of these shares exists
with respect to that matter. Except as otherwise provided in the Articles of
Incorporation or by law, a majority of the shares entitled to vote on the matter
by each voting group, represented in person or by proxy, shall constitute a
quorum at any meeting of shareholders, but in no event shall a quorum consist of
less than one-third (1/3) of the shares of each voting group entitled to vote.
If less than a majority of outstanding shares entitled to vote are represented
at a meeting, a majority of the shares so represented may adjourn the meeting
from time to time without further notice. After a quorum has been established at
any shareholders' meeting, the subsequent withdrawal of shareholders, so as to
reduce the number of shares entitled to vote at the meeting below the number
required for a quorum, shall not affect the validity of any action taken at the
meeting or any adjournment thereof. Once a share is represented for any purpose
at a meeting, it is


                                       -2-


<PAGE>

deemed present for quorum purposes for the remainder of the meeting and for any
adjournment of that meeting unless a new record date is or must be set for that
adjourned meeting.

         Section 8. VOTING PER SHARE. Except as otherwise provided in the
Articles of Incorporation or by law, each shareholder is entitled to one (1)
vote for each outstanding share held by him on each matter voted at a
shareholders' meeting.

         Section 9. VOTING OF SHARES. A shareholder may vote at any meeting of
shareholders of the Corporation, either in person or by proxy. Shares standing
in the name of another corporation, domestic or foreign, may be voted by the
officer, agent or proxy designated by the bylaws of such corporate shareholder
or, in the absence of any applicable bylaw, by such person or persons as the
board of directors of the corporate shareholder may designate. In the absence of
any such designation, or, in case of conflicting designation by the corporate
shareholder, the chairman of the board, the president, any vice president, the
secretary and the treasurer of the corporate shareholder, in that order, shall
be presumed to be fully authorized to vote such shares. Shares held by an
administrator, executor, guardian, personal representative, or conservator may
be voted by him, either in person or by proxy, without a transfer of such shares
into his name. Shares standing in the name of a trustee may be voted by him,
either in person or by proxy, but no trustee shall be entitled to vote shares
held by him without a transfer of such shares into his name or the name of his
nominee. Shares held by or under the control of a receiver, a trustee in
bankruptcy proceedings, or an assignee for the benefit of creditors may be voted
by such person without the transfer thereof into his name. If shares stand of
record in the names of two or more persons, whether fiduciaries, members of a
partnership, joint tenants, tenants in common, tenants by the entirety or
otherwise, or if two or more persons have the same fiduciary relationship
respecting the same shares, unless the Secretary of the Corporation is given
notice to the contrary and is furnished with a copy of the instrument or order
appointing them or creating the relationship wherein it is so provided, then
acts with respect to voting shall have the following effect: (a) if only one
votes, in person or by proxy, his act binds all; (b) if more than one vote, in
person or by proxy, the act of the majority so voting binds all; (c) if more
than one vote, in person or by proxy, but the vote is evenly split on any
particular matter, each faction is entitled to vote the share or shares in
question proportionally; or (d) if the instrument or order so filed shows that
any such tenancy is held in unequal interest, a majority or a vote evenly split
for purposes hereof shall be a majority or a vote evenly split in interest. The
principles of this paragraph shall apply, insofar as possible, to execution of
proxies, waivers, consents, or objections and for the purpose of ascertaining
the presence of a quorum.

         Section 10. PROXIES. Any shareholder of the Corporation, other person
entitled to vote on behalf of a shareholder pursuant to law, or attorney-in-fact
for such persons may vote the shareholders shares in person or by proxy. Any
shareholder of the Corporation may appoint a proxy to vote or otherwise act for
him by signing an appointment form, either personally or by his
attorney-in-fact. An executed telegram or cablegram appearing to have been
transmitted by such person, or a photographic, photostatic, or equivalent
reproduction of an appointment form, shall be deemed a sufficient appointment
form. An appointment of a proxy is effective when received by the Secretary of
the Corporation or such other officer or agent which is authorized


                                       -3-


<PAGE>

to tabulate votes, and shall be valid for up to 11 months, unless a longer
period is expressly provided in the appointment form. The death or incapacity of
the shareholder appointing a proxy does not affect the right of the Corporation
to accept the proxy's authority unless notice of the death or incapacity is
received by the secretary or other officer or agent authorized to tabulate votes
before the proxy exercises his authority under the appointment. An appointment
of a proxy is revocable by the shareholder unless the appointment is coupled
with an interest.

         Section 11. SHAREHOLDER LIST. After fixing a record date for a meeting
of shareholders, the Corporation shall prepare an alphabetical list of the names
of all its shareholders who are entitled to notice of the meeting, arranged by
voting group with the address of, and the number and class and series, if any,
of shares held by each. The shareholders' list must be available for inspection
by any shareholder for a period of ten (10) days prior to the meeting or such
shorter time as exists between the record date and the meeting and continuing
through the meeting at the Corporation's principal office, at a place identified
in the meeting notice in the city where the meeting will be held, or at the
office of the Corporation's transfer agent or registrar. Any shareholder of the
Corporation or his agent or attorney is entitled on written demand to inspect
the shareholders' list (subject to the requirements of law), during regular
business hours and at his expense, during the period it is available for
inspection. The Corporation shall make the shareholders' list available at the
meeting of shareholders, and any shareholder or his agent or attorney is
entitled to inspect the list at any time during the meeting or any adjournment

         Section 12. ACTION WITHOUT MEETING. Any action required by law to be
taken at a meeting of shareholders, or any action that may be taken at a meeting
of shareholders, may be taken without a meeting or notice if a consent in
writing, setting forth the action so taken, shall be signed by the holders of
outstanding stock having not less than the minimum number of votes that would be
necessary to authorize or take such action at a meeting at which all shares
entitled to vote thereon were present and voted with respect to the subject
matter thereof, and such consent shall have the same force and effect as a vote
of shareholders taken at such a meeting.

         Section 13. FIXING RECORD DATE. For the purpose of determining
shareholders entitled to notice of or to vote at any meeting of shareholders or
any adjournment thereof or entitled to receive payment of any dividend, or in
order to make a determination of shareholders for any other proper purposes, the
Board of Directors may fix in advance a date as the record date for any such
determination of shareholders, such date in any case to be not more than sixty
(60) days, and, in case of a meeting of shareholders, not less than ten (10)
days, prior to the date on which the particular action requiring such
determination of shareholders is to be taken. If no record date is fixed for the
determination of shareholders entitled to notice of or to vote at a meeting of
shareholders, or shareholders entitled to receive payment of a dividend, the
date on which the notice of the meeting is mailed or the date on which the
resolutions of the Board of Directors declaring such dividend is adopted, as the
case may be, shall be the record date for such determination of shareholders.
When a determination of shareholders entitled to vote at any meeting of
shareholders has been made as provided in this Section 13, such determination


                                       -4-


<PAGE>

shall apply to any adjournment thereof, except where the Board of Directors
fixes a new record date for the adjourned meeting or as required by law.

         Section 14. INSPECTORS AND JUDGES. The Board of Directors in advance of
any meeting may, but need not, appoint one or more inspectors of election or
judges of the vote, as the case may be, to act at the meeting or any
adjournment(s) thereof. If any inspector or inspectors, or judge or judges, are
not appointed, the person presiding at the meeting may, but need not, appoint
one or more inspectors or judges. In case any person who may be appointed as an
inspector or judge fails to appear or act, the vacancy may be filled by the
Board of Directors in advance of the meeting, or at the meeting by the person
presiding thereat. The inspectors or judges, if any, shall determine the number
of shares of stock outstanding and the voting power of each, the shares of stock
represented at the meeting, the existence of a quorum, the validity and effect
of proxies, and shall receive votes, ballots and consents, hear and determine
all challenges and questions arising in connection with the right to vote, count
and tabulate votes, ballots and consents, determine the result, and do such acts
as are proper to conduct the election or vote with fairness to all shareholders.
On request of the person presiding at the meeting, the inspector or inspectors
or judge or judges, if any, shall make a report in writing of any challenge,
question or matter determined by him or them, and execute a certificate of any
fact found by him or them.

         Section 15. VOTING FOR DIRECTORS. Unless otherwise provided in the
Articles of Incorporation, directors shall be elected by a plurality of the
votes cast by the shares entitled to vote in the election at a meeting at which
a quorum is present.

                                  ARTICLE THREE

                                    DIRECTORS

         Section 1. NUMBER, ELECTION AND TERM. The number of directors of the
Corporation shall be fixed from time to time, within the limits specified by the
Articles of Incorporation, by resolution of the Board of Directors; provided,
however, no director's term shall be shortened by reason of a resolution
reducing the number of directors. The directors shall be elected at the annual
meeting of the shareholders, except as provided in Section 2 of this Article,
and each director elected shall hold office for the term for which he is elected
and until his successor is elected and qualified or until his earlier
resignation, removal from office or death. Directors must be natural persons who
are 18 years of age or older but need not be residents of the State of Florida,
shareholders of the Corporation or citizens of the United States. Any director
may be removed at any time, with or without cause, at a special meeting of the
shareholders called for that purpose.

         Section 2.  VACANCIES.  A director may resign at any time by giving 
written notice to the Corporation, the Board of Directors or the Chairman of the
Board.  Such resignation shall take effect when the notice is delivered unless 
the notice specifies a later effective date, in which


                                       -5-


<PAGE>

event the Board of Directors may fin the pending vacancy before the effective
date if they provide that the successor does not take office until the effective
date. Any vacancy occurring in the Board of Directors and any directorship to be
filled by reason of an increase in the size of the Board of Directors shall be
filled by the affirmative vote of a majority of the current directors though
less than a quorum of the Board of Directors, or may be filled by an election at
an annual or special meeting of the shareholders called for that purpose, unless
otherwise provided by law. A director elected to fill a vacancy shall be elected
for the unexpired term of his predecessor in office, or until the next election
of one or more directors by shareholders if the vacancy is caused by an increase
in the number of directors.

         Section 3. POWERS. Except as provided in the Articles of Incorporation
and by law, all corporate powers shall be exercised by or under the authority
of, and the business and affairs of the Corporation shall be managed under the
direction of, its Board of Directors.

         Section 4.  PLACE OF MEETINGS.  Meetings of the Board of Directors, 
regular or special, may be held either within or without the State of Florida.

         Section 5. ANNUAL MEETING. The first meeting of each newly elected
Board of Directors shall be held, without call or notice, immediately following
each annual meeting of shareholders.

         Section 6. REGULAR MEETINGS. Regular meetings of the Board of Directors
may also be held without notice at such time and at such place as shall from
time to time be determined by the Board of Directors.

         Section 7. SPECIAL MEETINGS AND NOTICE. Special meetings of the Board
of Directors may be called by the Chairman of the Board or by the President and
shall be called by the Secretary on the written request of any two directors.
Written notice of special meetings of the Board of Directors shall be given to
each director at least forty-eight (48) hours before the meeting. Except as
required by statute, neither the business to be transacted at, nor the purpose
of, any regular or special meeting of the Board of Directors need be specified
in the notice or waiver of notice of such meeting. Notices to directors shall be
in writing and delivered personally or mailed to the directors at their
addresses appearing on the books of the Corporation. Notice by mail shall be
deemed to be given at the time when the same shall be received. Notice to
directors may also be given by telegram, teletype or other form of electronic
communication. Notice of a meeting of the Board of Directors need not be given
to any director who signs a written waiver of notice before, during or after the
meeting. Attendance of a director at a meeting shall constitute a waiver of
notice of such meeting and a waiver of any and all objections to the place of
the meeting, the time of the meeting and the manner in which it has been called
or convened, except when a director states, at the beginning of the meeting or
promptly upon arrival at the meeting, any objection to the transaction of
business because the meeting is not lawfully called or convened.

         Section 8.  QUORUM; REQUIRED VOTE; PRESUMPTION OF ASSENT.  A majority 
of the number of directors fixed by, or in the manner provided in, these bylaws 
shall constitute a quorum for


                                       -6-


<PAGE>

the transaction of business; provided, however, that whenever, for any reason, a
vacancy occurs in the Board of Directors, a quorum shall consist of a majority
of the remaining directors until the vacancy has been filled. The act of a
majority of the directors present at a meeting at which a quorum is present when
the vote is taken shall be the act of the Board of Directors. A director of the
Corporation who is present at a meeting of the Board of Directors or a committee
of the Board of Directors when corporate action is taken shall be presumed to
have assented to the action taken, unless he objects at the beginning of the
meeting, or promptly upon his arrival, to holding the meeting or transacting
specific business at the meeting, or he votes against or abstains from the
action taken.

         Section 9. ACTION WITHOUT MEETING. Any action required or permitted to
be taken at a meeting of the Board of Directors or a committee thereof may be
taken without a meeting if a consent in writing, setting forth the action taken,
is signed by all of the members of the Board of Directors or the committee, as
the case may be, and such consent shall have the same force and effect as a
unanimous vote at a meeting. Action taken under this section is effective when
the last director signs the consent, unless the consent specifies a different
effective date. A consent signed under this Section 9 shall have the effect of a
meeting vote and may be described as such in any document.

         Section 10. CONFERENCE TELEPHONE OR SIMILAR COMMUNICATIONS EQUIPMENT
MEETINGS. Members of the Board of Directors may participate in a meeting of the
Board by means of conference telephone or similar communications equipment by
means of which all persons participating in the meeting can hear each other at
the same time. Participation in such a meeting shall constitute presence in
person at the meeting, except where a person participates in the meeting for the
express purpose of objecting to the transaction of any business on the ground
the meeting is not lawfully called or convened.

         Section 11. COMMITTEES. The Board of Directors, by resolution adopted
by a majority of the full Board of Directors, may designate from among its
members an executive committee and one or more other committees, each of which,
to the extent provided in such resolution, shall have and may exercise all of
the authority of the Board of Directors in the business and affairs of the
Corporation except where the action of the full Board of Directors is required
by statute. Each committee must have two or more members who serve at the
pleasure of the Board of Directors. The Board of Directors, by resolution
adopted in accordance with this Article Three, may designate one or more
directors as alternate members of any committee, who may act in the place and
stead of any absent member or members at any meeting of such committee.
Vacancies in the membership of a committee shall be filled by the Board of
Directors at a regular or special meeting of the Board of Directors. The
executive committee shall keep regular minutes of its proceedings and report the
same to the Board of Directors when required. The designation of any such
committee and the delegation thereto of authority shall not operate to relieve
the Board of Directors, or any member thereof, of any responsibility imposed
upon it or him by law.


                                       -7-


<PAGE>

         Section 12. COMPENSATION OF DIRECTORS. The directors may be paid their
expenses, if any, of attendance at each meeting of the Board of Directors and
may be paid a fixed sum for attendance at each meeting of the Board of Directors
or a stated salary as director. No such payment shall preclude any director from
serving the Corporation in any other capacity and receiving compensation
therefor. Members of special or standing committees may be allowed like
compensation for attending committee meetings.

                                  ARTICLE FOUR

                                    OFFICERS

         Section 1. POSITIONS. The officers of the Corporation shall consist of
a President, Chief Executive Officer, one or more Vice Presidents, a Secretary

         Section 2. ELECTION OF SPECIFIED OFFICERS BY BOARD. The Board of
Directors at its first meeting after each annual meeting of shareholders shall
elect a President, one or more Vice Presidents, a Secretary and a Treasurer.

         Section 3. ELECTION OR APPOINTMENT OF OTHER OFFICERS. Such other
officers and assistant officers and agents as may be deemed necessary may be
elected or appointed by the Board of Directors, or, unless otherwise specified
herein, appointed by the President of the Corporation. The Board of Directors
shall be advised of appointments by the President at or before the next
scheduled Board of Directors meeting.

         Section 4. SALARIES. The salaries of all officers of the Corporation to
be elected by the Board of Directors pursuant to Article Four, Section 2 hereof
shall be fixed from time to time by the Board of Directors or pursuant to its
discretion. The salaries of all other elected or appointed officers of the
Corporation shall be fixed from time to time by the President of the Corporation
or pursuant to his direction.

         Section 5. TERM; RESIGNATION. The officers of the Corporation shall
hold office until their successors are chosen and qualified. Any officer or
agent elected or appointed by the Board of Directors or the President of the
Corporation may be removed, with or without cause, by the Board of Directors.
Any officers or agents appointed by the President of the Corporation pursuant to
Section 3 of this Article Four may also be removed from such officer positions
by the President, with or without cause. Any vacancy occurring in any office of
the Corporation by death, resignation, removal or otherwise shall be filled by
the Board of Directors, or, in the case of an officer appointed by the President
of the Corporation, by the President or the Board of Directors. Any officer of
the Corporation may resign from his respective office or position by delivering
notice to the Corporation. Such resignation is effective when delivered unless
the notice specifies a later effective date. If a resignation is made effective
at a later date and the


                                       -8-


<PAGE>

Corporation accepts the future effective date, the Board of Directors may fill
the pending vacancy before the effective date if the Board provides that the
successor does not take office until the effective date.

         Section 6. CHAIRMAN OF THE BOARD. The Board of Directors may, in its
discretion, choose a chairman of the board who shall preside at meetings of the
shareholders and of the directors and shall be an ex officio member of all
standing committees. The Chairman of the Board shall be the Chief Executive
Officer of the Corporation and shall have such other powers and shall perform
such other duties as shall be designated by the Board of Directors. The Chairman
of the Board shall be a member of the Board of Directors but no other officers
of the Corporation need be a director. The Chairman of the Board shall serve
until his successor is chosen and qualified, but he may be removed at any time
by the affirmative vote of a majority of the Board of Directors.

         Section 7. PRESIDENT. The President shall be the Chief Operating
Officer of the Corporation, shall have general and active management of the
business of the Corporation and shall see that all orders and resolutions of the
Board of Directors are carried into effect. In the absence of the Chairman of
the Board or in the event the Board of Directors shall not have designated a
chairman of the board, the President shall preside at meetings of the
shareholders and the Board of Directors.

         Section 8. VICE PRESIDENTS. The Vice Presidents in the order of their
seniority, unless otherwise determined by the Board of Directors, shall in the
absence or disability of the President, perform the duties and exercise the
powers of the President. They shall perform such other duties and have such
other powers as the Board of Directors shall prescribe or as the President may
from time to time delegate.

         Section 9. SECRETARY. The Secretary shall attend all meetings of the
Board of Directors and all meetings of the shareholders and record all the
proceedings of the meetings of the shareholders and of the Board of Directors in
a book to be kept for that purpose and shall perform like duties for the
standing committees when required. He shall give, or cause to be given, notice
of all meetings of the shareholders and special meetings of the Board of
Directors, and shall perform such other duties as may be prescribed by the Board
of Directors or President, under whose supervision he shall be. He shall keep in
safe custody the seal of the Corporation and, when authorized by the Board of
Directors, affix the same to any instrument requiring it.

         Section 10. TREASURER. The Treasurer shall have the custody of
corporate funds and securities and shall keep full and accurate accounts of
receipts and disbursements in books belonging to the Corporation and shall
deposit all moneys and other valuable effects in the name and to the credit of
the Corporation in such depositories as may be designated by the Board of
Directors. He shall disburse the funds of the Corporation as may be ordered by
the Board of Directors, taking proper vouchers for such disbursements, and shall
render to the President and the Board of Directors at its regular meetings or
when the Board of Directors so requires an account of all his transactions as
treasurer and of the financial condition of the Corporation


                                       -9-


<PAGE>



unless otherwise specified by the Board of Directors, the Treasurer shall be the
Corporation's Chief Financial Officer.

         Section 11. OTHER OFFICERS, EMPLOYEES AND AGENTS. Each and every other
officer, employee and agent of the Corporation shall possess, and may exercise,

time be assigned to him by the Board of Directors, the officer so appointing him
and such officer or officers who may from time to time be designated by the

                                  ARTICLE FIVE

                             CERTIFICATES FOR SHARES

         Section 1. ISSUE OF CERTIFICATES. The Corporation shall deliver
certificates representing all shares to which shareholders are entitled; and
such certificates shall be signed by the Chairman of the Board, President or a
Vice President, and by the Secretary or an Assistant Secretary of the
Corporation, and may be sealed with the seal of the Corporation or a facsimile
thereof.

         Section 2. LEGENDS FOR PREFERENCES AND RESTRICTIONS ON TRANSFER. The
designations, relative rights, preferences and limitations applicable to each
class of shares and the variations in rights, preferences and limitations
determined for each series within a class (and the authority of the Board of
Directors to determine variations for future series) shall be summarized on the
front or back of each certificate. Alternatively, each certificate may state
conspicuously on its front or back that the Corporation will furnish the
shareholder a full statement of this information on request and without charge.
Every certificate representing shares that are restricted as to the sale,
disposition, or transfer of such shares shall also indicate that such shares are
restricted as to transfer and there shall be set forth or fairly summarized upon
the certificate, or the certificate shall indicate that the Corporation will
furnish to any shareholder upon request and without charge, a full statement of
such restrictions. If the Corporation issues any shares that are not registered
under the Securities Act of 1933, as amended, and registered or qualified under
the applicable state securities laws, the transfer of any such shares shall be
restricted substantially in accordance with the following legend:

                  THESE SHARES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
         OF 1933 OR UNDER ANY APPLICABLE STATE LAW. THEY MAY NOT BE OFFERED FOR
         SALE, SOLD, TRANSFERRED OR PLEDGED WITHOUT (1) REGISTRATION UNDER THE
         SECURITIES ACT OF 1933 AND ANY APPLICABLE STATE LAW OR (2) AT HOLDER'S
         EXPENSE, AN OPINION (SATISFACTORY TO THE CORPORATION) OF COUNSEL
         (SATISFACTORY TO THE CORPORATION) THAT REGISTRATION IS NOT REQUIRED.

<PAGE>

         Section 3. FACSIMILE SIGNATURES. The signatures of the Chairman of the
Board, the President or a Vice President and the Secretary or Assistant
Secretary upon a certificate may be facsimiles, if the certificate is manually
signed by a transfer agent, or registered by a registrar, other than the
Corporation itself or an employee of the Corporation. In case any officer who
has signed or whose facsimile signature has been placed upon such certificate
shall have ceased to be such officer before such certificate is issued, it may
be issued by the Corporation with the same effect as if he were such officer at
the date of the issuance.

         Section 4. LOST CERTIFICATES. The Board of Directors may direct a new
certificate or certificates to be issued in place of any certificate or
certificates theretofore issued by the Corporation alleged to have been lost or
destroyed, upon the making of an affidavit of that fact by the person claiming
the certificate of stock to be lost or destroyed. When authorizing such issue of
a new certificate or certificates, the Board of Directors may, in its discretion
and as a condition precedent to the issuance thereof require the owner of such
lost or destroyed certificate or certificates, or his legal representative, to
advertise the same in such manner as it shall require and/or to give the
Corporation a bond in such sum as it may direct as indemnity against any claim
that may be made against the Corporation with respect to the certificate alleged
to have been lost or destroyed.

         Section 5. TRANSFER OF SHARES. Upon surrender to the Corporation or the
transfer agent of the Corporation of a certificate for shares duly endorsed or
accompanied by proper evidence of succession, assignment or authority to
transfer, it shall be the duty of the Corporation to issue a new certificate to
the person entitled thereto, cancel the old certificate and record the
transaction upon its books.

         Section 6. REGISTERED SHAREHOLDERS. The Corporation shall be entitled
to recognize the exclusive rights of a person registered on its books as the
owner of shares to receive dividends, and to vote as such owner, and shall not
be bound to recognize any equitable or other claim to or interest in such share
or shares on the part of any other person, whether or not it shall have express
or other notice thereof except as otherwise provided by the laws of the State of
Florida.

         Section 7. REDEMPTION OF CONTROL SHARES. As provided by the Florida
Business Corporation Act, if a person acquiring control shares of the
Corporation does not file an acquiring person statement with the Corporation,
the Corporation may redeem the control shares at fair market value at any time
during the 60-day period after the last acquisition of such control shares. If a
person acquiring control shares of the Corporation files an acquiring person
statement with the Corporation, the control shares may be redeemed by the
Corporation only ff such shares are not accorded full voting rights by the
shareholders as provided by law.

                                   ARTICLE SIX

                               GENERAL PROVISIONS

                        DATED AS OF ______________, 1997


<PAGE>




                  ADVISOR'S WARRANT AGREEMENT dated as of ______________, 1997
between NETSPEAK CORPORATION, a Florida corporation (the "Company"), and
JOSEPHTHAL LYON & ROSS INCORPORATED (hereinafter referred to variously as the
"Holder", "Josephthal" or the "Representative").

                              W I T N E S S E T H:

                  WHEREAS, the Company proposes to issue to Josephthal or its
designees warrants ("Warrants") to purchase up to an aggregate 200,000 shares of
common stock of the Company ("Common Stock"); and

                  WHEREAS, Josephthal has agreed pursuant to the underwriting
agreement (the "Underwriting Agreement") dated as of the date hereof among
Josephthal, [Co-Manager] ("[Co-Manager]", collectively with Josephthal, the
"Representatives") as the Representatives of the Several Underwriters named in
Schedule A thereto, and the Company to act as a Representative in connection
with the Company's proposed public offering of up to 2,000,000 shares of Common
Stock at a public offering price of $____ per share of Common Stock (the "Public
Offering"); and

                  WHEREAS, the Warrants to be issued pursuant to this Agreement
will be issued on the Closing Date (as such term is defined in the Underwriting
Agreement) by the Company to Josephthal in consideration for, and as part of
Josephthal's compensation in connection with, Josephthal providing the Company
with financial advisory services;

<PAGE>



                  NOW, THEREFORE, in consideration of the premises, the payment
by Josephthal to the Company of an aggregate of twenty dollars ($20.00), the
agreements herein set forth and other good and valuable consideration, hereby
acknowledged, the parties hereto agree as follows:

                  1. GRANT. Josephthal is hereby granted the right to purchase,
at any time from ___________, 1998 [one year from the effective date of the
registration statement], until 5:30 P.M., New York time, on ______________, 2002
[five years from the effective date of the registration statement], up to an
aggregate of 200,000 shares of Common Stock (the "Shares") at an initial
exercise price (subject to adjustment as provided in SECTION 8 hereof) of $____
per share [120% of the initial public offering price per share] of Common Stock
subject to the terms and conditions of this Agreement. Except as set forth
herein, the Shares issuable upon exercise of the Warrants are in all respects
identical to the shares of Common Stock being purchased by the Underwriters for
resale to the public pursuant to the terms and provisions of the Underwriting
Agreement.

                  2. WARRANT CERTIFICATES. The warrant certificates (the
"Warrant Certificates") delivered and to be delivered pursuant to this Agreement
shall be in the form set forth in Exhibit A, attached hereto and made a part
hereof, with such appropriate insertions, omissions, substitutions, and other
variations as required or permitted by this Agreement.

                  3.       EXERCISE OF WARRANT.

                  /section/ 3.1 METHOD OF EXERCISE. The Warrants initially are
exercisable at an aggregate initial exercise price (subject to adjustment as
provided in Section 8 hereof) per share of Common Stock set forth in SECTION 6
hereof payable by certified or official bank check in New York Clearing House
funds, subject to adjustment as provided in SECTION 8 hereof. Upon surrender of
a Warrant Certificate with the annexed Form of Election to Purchase duly
executed,

                                       2
<PAGE>

together with payment of the Exercise Price (as hereinafter defined) for the
shares of Common Stock purchased at the Company's principal offices in Boca
Raton, Florida (presently located at 902 Clint Moore Road, Suite 104, Boca
Raton, Florida 33487) the registered holder of a Warrant Certificate ("Holder"
or "Holder") shall be entitled to receive a certificate or certificates for the
shares of Common Stock so purchased. The purchase rights represented by each
Warrant Certificate are exercisable at the option of the Holder thereof, in
whole or in part (but not as to fractional shares of the Common Stock underlying
the Warrants). Warrants may be exercised to purchase all or part of the shares
of Common Stock represented thereby. In the case of the purchase of less than
all the shares of Common Stock purchasable under any Warrant Certificate, the
Company shall cancel said Warrant Certificate upon the surrender thereof and
shall execute and deliver a new Warrant Certificate of like tenor for the
balance of the shares of Common Stock purchasable thereunder.

                  ss.3.2 EXERCISE BY SURRENDER OF WARRANT. In addition to the
method of payment set forth in SECTION 3.1 and in lieu of any cash payment
required thereunder, the Holder(s) of the Warrants shall have the right at any
time and from time to time to exercise the Warrants in full or in part by
surrendering the Warrant Certificate in the manner specified in SECTION 3.1 in
exchange for the number of Shares equal to the product of (x) the number of
Shares as to which the Warrants are being exercised multiplied by (y) a
fraction, the numerator of which is the Market Price (as defined in SECTION 3.3
below) of the Shares less the Exercise Price and the denominator of which is
such Market Price. Solely for the purposes of this paragraph, Market Price shall
be calculated either (i) on the date which the form of election attached hereto
is deemed to have been sent to the Company pursuant to SECTION 13 hereof
("Notice Date") or (ii)


                                       3
<PAGE>

as the average of the Market Prices for each of the five trading days preceding
the Notice Date, whichever of (i) or (ii) is greater.

                  /section/ 3.3 DEFINITION OF MARKET PRICE. As used herein, the
phrase "Market Price" at any date shall be deemed to be the last reported sale
price, or, in case no such reported sale takes place on such day, the average of
the last reported sale prices for the last three (3) trading days, in either
case as officially reported by the principal securities exchange on which the
Common Stock is listed or admitted to trading or by the Nasdaq National Market
("NNM"), or, if the Common Stock is not listed or admitted to trading on any
national securities exchanged or quoted by NNM, the average closing bid price as
furnished by the NASD through NNM or similar organization if NNM is no longer
reporting such information, or if the Common Stock is not quoted on NNM, as
determined in good faith by resolution of the Board of Directors of the Company,
based on the best information available to it. 

                  4. ISSUANCE OF CERTIFICATES. Upon the exercise of the
Warrants, the issuance of certificates for shares of Common Stock and/or other
securities, properties or rights underlying such Warrants, shall be made
forthwith (and in any event within five (5) business days thereafter) without
charge to the Holder thereof including, without limitation, any tax which may be
payable in respect of the issuance thereof, and such certificates shall (subject
to the provisions of SECTIONS 5 and 7 hereof) be issued in the name of, or in
such names as may be directed by, the Holder thereof; provided, however, that
the Company shall not be required to pay any tax which may be payable in respect
of any transfer involved in the issuance and delivery of any such certificates
in a name other than that of the Holder, and the Company shall not be required
to issue or deliver such certificates unless or until the person or persons

                                       4
<PAGE>

requesting the issuance thereof shall have paid to the Company the amount of
such tax or shall have established to the satisfaction of the Company that such
tax has been paid.

                  The Warrant Certificates and the certificates representing the
Shares underlying the Warrants (and/or other securities, property or rights
issuable upon the exercise of the Warrants) shall be executed on behalf of the
Company by the manual or facsimile signature of the then Chairman or Vice
Chairman of the Board of Directors or President or Vice President of the
Company. Warrant Certificates shall be dated the date of execution by the
Company upon initial issuance, division, exchange, substitution or transfer.

                  5. RESTRICTION ON TRANSFER OF WARRANTS. The Holder of a
Warrant Certificate, by its acceptance thereof, covenants and agrees that the
Warrants are being acquired as an investment and not with a view to the
distribution thereof; that the Warrants may not be sold, transferred, assigned,
hypothecated or otherwise disposed of, in whole or in part, for a period of one
(1) year from the date hereof, except to officers of Josephthal.

                  6.       EXERCISE PRICE.

                  /section/ 6.1 INITIAL AND ADJUSTED EXERCISE PRICE. Except as
otherwise provided in SECTION 8 hereof, the initial exercise price of each
Warrant shall be $____ per share [120% of the initial public offering price per
share] of Common Stock. The adjusted exercise price shall be the price which
shall result from time to time from any and all adjustments of the initial
exercise price in accordance with the provisions of SECTION 8 hereof.

                  /section/ 6.2 EXERCISE PRICE. The term "Exercise Price" herein
shall mean the initial exercise price or the adjusted exercise price, depending
upon the context.

                  7.       REGISTRATION RIGHTS.

                  /section/ 7.1 REGISTRATION UNDER THE SECURITIES ACT OF 1933.
The Warrants, the Shares, and any of the other securities issuable upon exercise
of the Warrants have been registered under the Securities Act of 1933, as
amended (the "Act"), pursuant to the Company's Registration Statement on Form
S-1 (Registration No. 333-_____) (the "Registration Statement"). All of the
representations and warranties of the Company contained in the Underwriting
Agreement relating to the Registration Statement, the Preliminary Prospectus and
Prospectus (as such terms are defined in the Underwriting Agreement) and made as
of the dates provided therein, are hereby incorporated by reference. The Company
agrees and covenants promptly to file post-effective amendments to such
Registration Statement as may be necessary in order to maintain its
effectiveness and otherwise to take such action as may be necessary to maintain
the effectiveness of the Registration Statement as long as any Warrants are
outstanding. In the event that, for any reason, whatsoever, the Company shall
fail to maintain the effectiveness of the Registration Statement, upon exercise,
in part or in whole, of the Warrants, certificates representing the Shares
underlying the Warrants, and any of the other securities issuable upon exercise
of the Warrants (collectively, the "Warrant Securities") shall bear the
following legend:

                  The securities represented by this certificate have not been
                  registered under the Securities Act of 1933, as amended
                  ("Act"), and may not be offered or sold except pursuant to (i)
                  an effective registration statement under the Act, (ii) to the
                  extent applicable, Rule 144 under the Act (or any similar rule
                  under such Act relating to the disposition of securities), or
                  (iii) an opinion of counsel, if such opinion shall be
                  reasonably satisfactory to counsel to the issuer, that an
                  exemption from registration under such Act is available.

                  /section/ 7.2 PIGGYBACK REGISTRATION. If, at any time
commencing after the date hereof and expiring seven (7) years from the date
hereof, the Company proposes to register any of

                                       6
<PAGE>

its securities under the Act (other than in connection with a merger or pursuant
to Form S-8) it will give written notice by registered mail, at least thirty
(30) days prior to the filing of each such registration statement, to Josephthal
and to all other Holder(s) of the Warrants and/or the Warrant Securities of its
intention to do so. If Josephthal or other Holder(s) of the Warrants and/or
Warrant Securities notify the Company within twenty (20) business days after
receipt of any such notice of its or their desire to include any such securities
in such proposed registration statement, the Company shall afford Josephthal and
such Holder(s) of the Warrants and/or Warrant Securities the opportunity to have
any such Warrant Securities registered under such registration statement
(sometimes referred to herein as the "Piggyback Registration").

                  Notwithstanding the provisions of this SECTION 7.2, the
Company shall have the right at any time after it shall have given written
notice pursuant to this SECTION 7.2 (irrespective of whether a written request
for inclusion of any such securities shall have been made) to elect not to file
any such proposed registration statement, or to withdraw the same after the
filing but prior to the effective date thereof.

                  /section/ 7.3     DEMAND REGISTRATION.

                  (a) At any time commencing one year after the date hereof and
expiring five (5) years from the date hereof, the Holder of the Warrants and/or
Warrant Securities representing a "Majority" (as hereinafter defined) of such
securities (assuming the exercise of all of the Warrants) shall have the right
(which right is in addition to the registration rights under SECTION 7.2
hereof), exercisable by written notice to the Company, to have the Company
prepare and file with the Securities and Exchange Commission (the "Commission"),
on one occasion, a registration statement and such other documents, including a
prospectus, as may

                                       7
<PAGE>

be necessary in the opinion of both counsel for the Company and counsel for
Josephthal and Holder, in order to comply with the provisions of the Act, so as
to permit a public offering and sale of their respective Warrant Securities for
nine (9) consecutive months by such Holder and any other Holder of the Warrants
and/or Warrant Securities who notify the Company within ten (10) days after
receiving notice from the Company of such request.

                  (b) The Company covenants and agrees to give written notice of
any registration request under this SECTION 7.3 by any Holder or Holder(s) to
all other registered Holder(s) of the Warrants and the Warrant Securities within
ten (10) days from the date of the receipt of any such registration request.

                  (c) In addition to the registration rights under SECTION 7.2
and subsection (a) of this SECTION 7.3, at any time commencing after the date
hereof and expiring five (5) years thereafter, any Holder of Warrants and/or
Warrant Securities shall have the right, exercisable by written request to the
Company, to have the Company prepare and file, on one occasion, with the
Commission a registration statement so as to permit a public offering and sale
for nine (9) consecutive months by any such Holder of its Warrant Securities,
provided, however, that the provisions of SECTION 7.4(b) hereof shall not apply
to any such registration request and registration and all costs incident thereto
shall be at the expense of the Holder or Holders making such request.

                  (d) Notwithstanding anything to the contrary contained herein,
the Company shall have the option to repurchase any and all Warrant Securities
at the Market Price per share of Common Stock on the date of the notice sent
pursuant to SECTION 7.3(a) less the Exercise Price of such Warrant. Such
repurchase shall be in immediately available funds and shall close

                                       8
<PAGE>

within two (2) days after the later of (i) the expiration of the period
specified in SECTION 7.4(a) or (ii) the delivery of the written notice of
election specified in this SECTION 7.3(d).

                  /section/ 7.4 COVENANTS OF THE COMPANY WITH RESPECT TO
REGISTRATION. In connection with any registration under SECTION 7.2 or 7.3
hereof, the Company covenants and agrees as follows:

                  (a) The Company shall use its best efforts to file a
registration statement within forty-five (45) days of receipt of any demand
therefor, shall use its best efforts to have any registration statements
declared effective at the earliest possible time, and shall furnish each Holder
desiring to sell Warrant Securities such number of prospectuses as shall
reasonably be requested.

                  (b) The Company shall pay all costs (excluding fees and
expenses of Holder(s)' counsel and any underwriting or selling commissions),
fees and expenses in connection with all registration statements filed pursuant
to SECTIONS 7.2 and 7.3(a) hereof including, without limitation, the Company's
legal and accounting fees, printing expenses, blue sky fees and expenses. The
Holder(s) will pay all costs, fees and expenses in connection with any
registration statement filed pursuant to SECTION 7.3(c). If the Company shall
fail to comply with the provisions of SECTION 7.4(a), the Company shall, in
addition to any other equitable or other relief available to the Holder(s), be
liable for any or all incidental or special damages sustained by the Holder(s)
requesting registration of their Warrant Securities.

                  (c) The Company will take all necessary action which may be
required in qualifying or registering the Warrant Securities included in a
registration statement for offering and sale under the securities or blue sky
laws of such states as reasonably are requested by the Holder(s), provided that
the Company shall not be obligated to execute or file any general

                                       9
<PAGE>



consent to service of process or to qualify as a foreign corporation to do
business under the laws of any such jurisdiction.

                  (d) The Company shall indemnify the Holder(s) of the Warrant
Securities to be sold pursuant to any registration statement and each person, if
any, who controls such Holder within the meaning of SECTION 15 of the Act or
SECTION 20(a) of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), against all loss, claim, damage, expense or liability (including all
expenses reasonably incurred in investigating, preparing or defending against
any claim whatsoever) to which any of them may become subject under the Act, the
Exchange Act or otherwise, arising from such registration statement but only to
the same extent and with the same effect as the provisions pursuant to which the
Company has agreed to indemnify each of the Underwriters contained in SECTION 7
of the Underwriting Agreement.

                  (e) The Holder(s) of the Warrant Securities to be sold
pursuant to a registration statement, and their successors and assigns, shall
severally, and not jointly, indemnify the Company, its officers and directors
and each person, if any, who controls the Company within the meaning of SECTION
15 of the Act or SECTION 20(a) of the Exchange Act, against all loss, claim,
damage or expense or liability (including all expenses reasonably incurred in
investigating, preparing or defending against any claim whatsoever) to which
they may become subject under the Act, the Exchange Act or otherwise, arising
from information furnished by or on behalf of such Holder, or their successors
or assigns, for specific inclusion in such registration statement to the same
extent and with the same effect as the provisions contained in SECTION 7 of the
Underwriting Agreement pursuant to which the Underwriters have agreed to
indemnify the Company.

                                       10
<PAGE>

                  (f) Nothing contained in this Agreement shall be construed as
requiring the Holder(s) to exercise their Warrants prior to the initial filing
of any registration statement or the effectiveness thereof.

                  (g) The Company shall not permit the inclusion of any
securities other than the Warrant Securities to be included in any registration
statement filed pursuant to SECTION 7.3 hereof, or permit any other registration
statement to be or remain effective during the effectiveness of a registration
statement filed pursuant to SECTION 7.3 hereof, without the prior written
consent of the Holder(s) of the Warrants and Warrant Securities representing a
Majority of such securities.

                  (h) The Company shall furnish to each Holder participating in
the offering and to each underwriter, if any, a signed counterpart, addressed to
such Holder or underwriter, of (i) an opinion of counsel to the Company, dated
the effective date of such registration statement (and, if such registration
includes an underwritten public offering, an opinion dated the date of the
closing under the underwriting agreement), and (ii) a "cold comfort" letter
dated the effective date of such registration statement (and, if such
registration includes an underwritten public offering, a letter dated the date
of the closing under the underwriting agreement) signed by the independent
public accountants who have issued a report on the Company's financial
statements included in such registration statement, in each case covering
substantially the same matters with respect to such registration statement (and
the prospectus included therein) and, in the case of such accountants' letter,
with respect to events subsequent to the date of such financial statements, as
are customarily covered in opinions of issuer's counsel and in accountants'
letters delivered to underwriters in underwritten public offerings of
securities.

                                       11
<PAGE>

                  (i) The Company shall as soon as practicable after the
effective date of the registration statement, and in any event within 15 months
thereafter, make "generally available to its security holders" (within the
meaning of Rule 158 under the Act) an earnings statement (which need not be
audited) complying with SECTION 11(a) of the Act and covering a period of at
least 12 consecutive months beginning after the effective date of the
registration statement.

                  (j) The Company shall deliver promptly to each Holder
participating in the offering requesting the correspondence and memoranda
described below and to the managing underwriters, copies of all correspondence
between the Commission and the Company, its counsel or auditors and all
memoranda relating to discussions with the Commission or its staff with respect
to the registration statement and permit each Holder and underwriters to do such
investigation, upon reasonable advance notice, with respect to information
contained in or omitted from the registration statement as it deems reasonably
necessary to comply with applicable securities laws or rules of the National
Association of Securities Dealers, Inc. ("NASD"). Such investigation shall
include access to books, records and properties and opportunities to discuss the
business of the Company with its officers and independent auditors, all to such
reasonable extent and at such reasonable times and as often as any such Holder
or underwriter shall reasonably request.

                  (k) The Company shall enter into an underwriting agreement
with the managing underwriters selected for such underwriting by Holder(s)
holding a Majority of the Warrant Securities requested to be included in such
underwriting, which may be Josephthal. Such agreement shall be satisfactory in
form and substance to the Company, each Holder and such managing underwriters,
and shall contain such representations, warranties and covenants by the Company
and such other terms as are customarily contained in agreements of that type

                                       12
<PAGE>

used by the managing underwriter. The Holder(s) shall be parties to any
underwriting agreement relating to an underwritten sale of their Warrant
Securities and may, at their option, require that any or all the
representations, warranties and covenants of the Company to or for the benefit
of such underwriters shall also be made to and for the benefit of such
Holder(s). Such Holder(s) shall not be required to make any representations or
warranties to or agreements with the Company or the underwriters except as they
may relate to such Holder(s) and their intended methods of distribution.

                  (l) In addition to the Warrant Securities, upon the written
request therefor by any Holder(s), the Company shall include in the registration
statement any other securities of the Company held by such Holder(s) as of the
date of filing of such registration statement, including without limitation
restricted shares of Common Stock, options, warrants or any other securities
convertible into shares of Common Stock.

                  (m) For purposes of this Agreement, the term "Majority" in
reference to the Holder(s) of Warrants or Warrant Securities, shall mean in
excess of fifty percent (50%) of the then outstanding Warrants or Warrant
Securities that (i) are not held by the Company, an affiliate, officer,
creditor, employee or agent thereof or any of their respective affiliates,
members of their family, persons acting as nominees or in conjunction therewith
and (ii) have not been resold to the public pursuant to a registration statement
filed with the Commission under the Act.

                  8.    ADJUSTMENTS TO EXERCISE PRICE AND NUMBER OF SECURITIES.

                  /section/ 8.1 SUBDIVISION AND COMBINATION. In case the Company
shall at any time subdivide or combine the outstanding shares of Common Stock,
the Exercise Price shall

                                       13
<PAGE>


forthwith be proportionately decreased in the case of subdivision or increased
in the case of combination.

                  /section/ 8.2 STOCK DIVIDENDS AND DISTRIBUTIONS. In case the
Company shall pay a dividend in, or make a distribution of, shares of Common
Stock or of the Company's capital stock convertible into Common Stock, the
Exercise Price shall forthwith be proportionately decreased. An adjustment made
pursuant to this SECTION 8.2 shall be made as of the record date for the subject
stock dividend or distribution.

                  /section/ 8.3 ADJUSTMENT IN NUMBER OF SECURITIES. Upon each
adjustment of the Exercise Price pursuant to the provisions of this SECTION 8,
the number of Warrant Securities issuable upon the exercise at the adjusted
exercise price of each Warrant shall be adjusted to the nearest whole number by
multiplying a number equal to the Exercise Price in effect immediately prior to
such adjustment by the number of Warrant Securities issuable upon exercise of
the Warrants immediately prior to such adjustment and dividing the product so
obtained by the adjusted Exercise Price.

                  /section/ 8.4 DEFINITION OF COMMON STOCK. For the purpose of
this Agreement, the term "Common Stock" shall mean (i) the class of stock
designated as Common Stock in the Articles of Incorporation of the Company as
may be amended as of the date hereof, or (ii) any other class of stock resulting
from successive changes or reclassifications of such Common Stock consisting
solely of changes in par value, or from par value to no par value, or from no
par value to par value.

                  /section/ 8.5 MERGER OR CONSOLIDATION. In case of any
consolidation of the Company with, or merger of the Company with, or merger of
the Company into, another corporation (other than a consolidation or merger
which does not result in any reclassification or change

                                       14
<PAGE>

of the outstanding Common Stock), the corporation formed by such consolidation
or merger shall execute and deliver to the Holder a supplemental warrant
agreement providing that the holder of each Warrant then outstanding or to be
outstanding shall have the right thereafter (until the expiration of such
Warrant) to receive, upon exercise of such warrant, the kind and amount of
shares of stock and other securities and property receivable upon such
consolidation or merger, by a holder of the number of shares of Common Stock of
the Company for which such warrant might have been exercised immediately prior
to such consolidation, merger, sale or transfer. Such supplemental warrant
agreement shall provide for adjustments which shall be identical to the
adjustments provided in SECTION 8. The above provision of this subsection shall
similarly apply to successive consolidations or mergers.

                  /section/ 8.6 NO ADJUSTMENT OF EXERCISE PRICE IN CERTAIN
CASES. No adjustment of the Exercise Price shall be made:

                           (a) Upon the issuance or sale of the Warrants or the
                  shares of Common Stock issuable upon the exercise of the
                  Warrants;

                           (b) If the amount of said adjustment shall be less
                  than two cents (2(cent)) per Warrant Security, provided,
                  however, that in such case any adjustment that would otherwise
                  be required then to be made shall be carried forward and shall
                  be made at the time of and together with the next subsequent
                  adjustment which, together with any adjustment so carried
                  forward, shall amount to at least two cents (2(cent)) per
                  Warrant Security.

                  9. EXCHANGE AND REPLACEMENT OF WARRANT CERTIFICATES. Each
Warrant Certificate is exchangeable without expense, upon the surrender thereof
by the registered Holder at the principal executive office of the Company, for a
new Warrant Certificate of like

                                       15
<PAGE>


tenor and date representing in the aggregate the right to purchase the same
number of Warrant Securities in such denominations as shall be designated by the
Holder thereof at the time of such surrender.

                  Upon receipt by the Company of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of any Warrant
Certificate, and, in case of loss, theft or destruction, of indemnity or
security reasonably satisfactory to it, and reimbursement to the Company of all
reasonable expenses incidental thereto, and upon surrender and cancellation of
the Warrants, if mutilated, the Company will make and deliver a new Warrant
Certificate of like tenor, in lieu thereof.

                  10. ELIMINATION OF FRACTIONAL INTERESTS. The Company shall not
be required to issue certificates representing fractions of shares of Common
Stock upon the exercise of the Warrants, nor shall it be required to issue scrip
or pay cash in lieu of fractional interests, it being the intent of the parties
that all fractional interests shall be eliminated by rounding any fraction up to
the nearest whole number of shares of Common Stock or other securities,
properties or rights.

                  11. RESERVATION AND LISTING OF SECURITIES. The Company shall
at all times reserve and keep available out of its authorized shares of Common
Stock, solely for the purpose of issuance upon the exercise of the Warrants,
such number of shares of Common Stock or other securities, properties or rights
as shall be issuable upon the exercise thereof. The Company covenants and agrees
that, upon exercise of the Warrants and payment of the Exercise Price therefor,
all shares of Common Stock and other securities issuable upon such exercise
shall be duly and validly issued, fully paid, non-assessable and not subject to
the preemptive rights of any stockholder. As long as the Warrants shall be
outstanding, the

                                       16
<PAGE>

Company shall use its best efforts to cause all shares of Common Stock issuable
upon the exercise of the Warrants to be listed (subject to official notice of
issuance) on all securities exchanges on which the Common Stock issued to the
public in connection herewith may then be listed and/or quoted.

                  12. NOTICES TO WARRANT HOLDER. Nothing contained in this
Agreement shall be construed as conferring upon the Holder the right to vote or
to consent or to receive notice as a stockholder in respect of any meetings of
stockholders for the election of directors or any other matter, or as having any
rights whatsoever as a stockholder of the Company. If, however, at any time
prior to the expiration of the Warrants and their exercise, any of the following
events shall occur: 

                           (a) the Company shall take a record of the holders of
                  its shares of Common Stock for the purpose of entitling them
                  to receive a dividend or distribution payable otherwise than
                  in cash, or a cash dividend or distribution payable otherwise
                  than out of current or retained earnings, as indicated by the
                  accounting treatment of such dividend or distribution on the
                  books of the Company; or

                           (b) the Company shall offer to all the holders of its
                  Common Stock any additional shares of capital stock of the
                  Company or securities convertible into or exchangeable for
                  shares of capital stock of the Company, or any option, right
                  or warrant to subscribe therefor; or

                           (c) a dissolution, liquidation or winding up of the
                  Company (other than in connection with a consolidation or
                  merger) or a sale of all or

                                       17
<PAGE>

                  substantially all of its property, assets and business as an 
                  entirety shall be proposed;

then, in any one or more of said events, the Company shall give written notice
of such event at least fifteen (15) days prior to the date fixed as a record
date or the date of closing the transfer books for the determination of the
stockholders entitled to such dividend, distribution, convertible or
exchangeable securities or subscription rights, or entitled to vote on such
proposed dissolution, liquidation, winding up or sale. Such notice shall specify
such record date or the date of closing the transfer books, as the case may be.
Failure to give such notice or any defect therein shall not affect the validity
of any action taken in connection with the declaration or payment of any such
dividend, or the issuance of any convertible or exchangeable securities, or
subscription rights, options or warrants, or any proposed dissolution,
liquidation, winding up or sale.

                  13.      NOTICES.

                  All notices, requests, consents and other communications
hereunder shall be in writing and shall be deemed to have been duly made and
sent when delivered, or mailed by registered or certified mail, return receipt
requested:

                           (a) If to a registered Holder of the Warrants, to the
                  address of such Holder as shown on the books of the Company;
                  or

                           (b) If to the Company, to the address set forth in
                  SECTION 3 hereof or to such other address as the Company may
                  designate by notice to the Holder.

                  14. SUPPLEMENTS AND AMENDMENTS. The Company and Josephthal may

holder of Warrant Certificates (other than Josephthal) in order to cure any
ambiguity, to correct or

supplement any provision contained herein which may be defective or inconsistent
with any provisions herein, or to make any other provisions in regard to matters
or questions arising hereunder which the Company and Josephthal may deem

adversely affect the interests of the Holder(s) of Warrant Certificates.

                  15. SUCCESSORS. All the covenants and provisions of this

indemnification provisions of SECTION 7 shall survive such termination until the
close of business on ______________, 2010.

                  17. GOVERNING LAW; SUBMISSION TO JURISDICTION. This Agreement
and each Warrant Certificate issued hereunder shall be deemed to be a contract
made under the laws of the State of New York and for all purposes shall be
construed in accordance with the laws of said State without giving effect to the
rules of said State governing the conflicts of laws.

                  The Company, Josephthal and the Holder hereby agree that any
action, proceeding or claim against it arising out of, or relating in any way
to, this Agreement shall be brought and enforced in the courts of the State of
New York or of the United States of America for the Southern District of New
York, and irrevocably submits to such jurisdiction, which jurisdiction shall be
exclusive. The Company, Josephthal and the Holder hereby irrevocably waive any
objection to such exclusive jurisdiction or inconvenient forum. Any such process
or summons to be served upon any of the Company, Josephthal and the Holder(s)
(at the option of the party bringing such action, proceeding or claim) may be
served by

                                       19

herein) contains the entire understanding between the parties hereto with
respect to the subject matter hereof and may not be modified or amended except
by a writing duly signed by the party against whom enforcement of the
modification or amendment is sought.

                  19. SEVERABILITY. If any provision of this Agreement shall be
held to be invalid or unenforceable, such invalidity or unenforceability shall
not affect any other provision of this Agreement.

                  20. CAPTIONS. The caption headings of the Sections of this

                               WARRANT CERTIFICATE

                  This Warrant Certificate certifies that _____________________,
or registered assigns, is the registered holder of _________________ Warrants to
purchase initially, at any time from ___________, 1997 [one year from the

____________, 2002 [five years from the effective date of the Registration
Statement] ("Expiration Date"), up to __________ fully-paid and non-assessable

as a "Security" and collectively as the "Securities") at the initial exercise
price, subject to adjustment in certain events (the "Exercise Price"), of $____
per share [120% of the initial public offering price per share] of Common Stock
upon surrender of this Warrant Certificate and payment of the Exercise Price at
an office or agency of the Company, but subject to the conditions set forth
herein and in the warrant agreement dated as of ______________, 1997 between the
Company, and JOSEPHTHAL LYON & ROSS INCORPORATED (the "Warrant Agreement").
Payment of the Exercise Price shall be made by certified or official bank check
in New York Clearing House funds payable to the order of the Company.


                                      A-1

                No Warrant may be exercised after 5:30 p.m., New York time, on
the Expiration Date, at which time all Warrants evidenced hereby, unless
exercised prior thereto, hereby shall thereafter be void.

                The Warrants evidenced by this Warrant Certificate are part of a
duly authorized issue of Warrants issued pursuant to the Warrant Agreement,
which Warrant Agreement is hereby incorporated by reference in and made a part
of this instrument and is hereby referred to for a description of the rights,
limitation of rights, obligations, duties and immunities thereunder of the
Company and the holder(s) (the words "holder" or "holder(s)" meaning the
registered holder or registered holder(s)) of the Warrants.

                The Warrant Agreement provides that upon the occurrence of
certain events the Exercise Price and the type and/or number of the Company's
securities issuable thereupon may, subject to certain conditions, be adjusted.
In such event, the Company will, at the request of the holder, issue a new
Warrant Certificate evidencing the adjustment in the Exercise Price and the
number and/or type of securities issuable upon the exercise of the Warrants;
provided, however, that the failure of the Company to issue such new Warrant
Certificates shall not in any way change, alter, or otherwise impair, the rights
of the holder as set forth in the Warrant Agreement.

                Upon due presentment for registration of transfer of this
Warrant Certificate at an office or agency of the Company, a new Warrant
Certificate or Warrant Certificates of like tenor and evidencing in the
aggregate a like number of Warrants shall be issued to the transferee(s) in
exchange for this Warrant Certificate, subject to the limitations provided
herein and in the Warrant Agreement, without any charge except for any tax or
other governmental charge imposed in connection with such transfer.

                Upon the exercise of less than all of the Warrants evidenced by
this Certificate, the Company shall forthwith issue to the holder hereof a new
Warrant Certificate representing such number of unexercised Warrants.

                The Company may deem and treat the registered holder(s) hereof
as the absolute owner(s) of this Warrant Certificate (notwithstanding any
notation of ownership or other writing hereon made by anyone), for the purpose
of any exercise hereof, and of any distribution to the holder(s) hereof, and for
all other purposes, and the Company shall not be affected by any notice to the
contrary.

                All terms used in this Warrant Certificate which are defined in
the Warrant Agreement shall have the meanings assigned to them in the Warrant
Agreement.

                                  (AS AMENDED)

         1. PURPOSE. The purpose of this Plan is to advance the interests of
NETSPEAK CORPORATION, a Florida corporation (the "Company"), by providing an
additional incentive to attract, retain and motivate highly qualified and
competent persons who are key to the Company, including key employees,
consultants, Officers and Directors, and upon whose efforts and judgment the
success of the Company and its Subsidiaries is largely dependent, by authorizing
the grant of options to purchase Common Stock of the Company to persons who are
eligible to participate hereunder, thereby encouraging stock ownership in the

corporations in such chain.

         3. SHARES AND OPTIONS. Subject to adjustment in accordance with Section
10 hereof, the Company may grant to Optionees from time to time Options to
purchase an aggregate of up to Two Million Seven Hundred Thousand (2,700,000)
Shares from Shares held in the Company's treasury or from authorized and
unissued Shares. If any Option granted under this Plan shall terminate, expire,
or be canceled, forfeited or surrendered as to any Shares, the Shares relating
to such lapsed Option shall be available for issuance pursuant to new Options
subsequently granted under this Plan. Upon the grant of any Option hereunder,
the authorized and unissued Shares to which such Option relates shall be
reserved for issuance to permit exercise under this Plan. Subject to the
provisions of Section 14 hereof, an Option granted hereunder shall be either an
Incentive Stock Option or a Non-Statutory Stock Option as determined by the
Committee at the time of grant of such Option and shall clearly state whether it
is an Incentive Stock Option or Non-Statutory Stock Option. All Incentive Stock
Options shall be granted within 10 years from the effective date of this Plan.

         4. LIMITATIONS. Options otherwise qualifying as Incentive Stock Options
hereunder will not be treated as Incentive Stock Options to the extent that the
aggregate Fair Market Value (determined at the time the Option is granted) of
the Shares, with respect to which Options meeting the requirements of Code
Section 422(b) are exercisable for the first time by any individual during any
calendar year (under all stock option or similar plans of the Company and any
Subsidiary), exceeds $100,000.

         5.       CONDITIONS FOR GRANT OF OPTIONS.

                  (a) Each Option shall be evidenced by an option agreement that
may contain any term deemed necessary or desirable by the Committee, provided
such terms are not inconsistent with this Plan or any applicable law. Optionees
shall be those persons selected by the Committee from the class of all regular
Employees of the Company or its Subsidiaries, including Employee Directors and
Officers who are regular or former regular employees of the Company, as well as
consultants to the Company. Any person who files with the Committee,


                                        4


<PAGE>

in a form satisfactory to the Committee, a written waiver of eligibility to
receive any Option under this Plan shall not be eligible to receive any Option
under this Plan for the duration of such waiver.

                  (b) In granting Options, the Committee shall take into
consideration the contribution the person has made, or is expected to make, to
the success of the Company or its Subsidiaries and such other factors as the
Committee shall determine. The Committee shall also have the authority to
consult with and receive recommendations from Officers and other personnel of
the Company and its Subsidiaries with regard to these matters. The Committee may
from time to time in granting Options under this Plan prescribe such terms and
conditions concerning such Options as it deems appropriate, including, without
limitation, (i) the exercise price or prices of the Option or any installments
thereof, (ii) prescribing the date or dates on which the Option becomes and/or
remains exercisable, (iii) providing that the Option vests or becomes
exercisable in installments over a period of time, and/or upon the attainment of
certain stated standards, specifications or goals, (iv) relating an Option to
the continued employment of the Optionee for a specified period of time, or (v)
conditions or termination events with respect to the exercisability of any
Option, provided that such terms and conditions are not more favorable to an
Optionee than those expressly permitted herein; PROVIDED, HOWEVER, all Incentive
Stock Options shall vest and become exercisable in three equal installments over
a three year period following the date of grant, one-third one year from the
date of grant, an additional one-third (or two-thirds cumulatively) two years
from the date of grant and 100% after three years from the date of grant.

                  (c) The Options granted to employees under this Plan shall be
in addition to regular salaries, pension, life insurance or other benefits
related to their employment with the Company or its Subsidiaries. Neither this
Plan nor any Option granted under this Plan shall confer upon any person any
right to employment or continuance of employment (or related salary and
benefits) by the Company or its Subsidiaries.

         6. EXERCISE PRICE. The exercise price per Share of any Option shall be
any price determined by the Committee but shall not be less than the par value
per Share; PROVIDED, HOWEVER, that in no event shall the exercise price per
Share of any Incentive Stock Option be less than the Fair Market Value of the
Shares underlying such Option on the date such Option is granted. Re-granted
Options, or Options which are canceled and then re-granted covering such
canceled Options, will, for purposes of this Section 6, be deemed to have been
granted on the date of the re-granting.

         7. EXERCISE OF OPTIONS.

                  (a) An Option shall be deemed exercised when (i) the Company
has received written notice of such exercise in accordance with the terms of the
Option, (ii) full payment of the aggregate option price of the Shares as to
which the Option is exercised has been made, (iii) the Optionee has agreed to be
bound by the terms, provisions and conditions of any applicable shareholders'
agreement, and (iv) arrangements that are satisfactory to the Committee in its
sole discretion have been made for the Optionee's payment to the Company of the
amount

                                        5


<PAGE>

that is necessary for the Company or the Subsidiary employing the Optionee to
withhold in accordance with applicable Federal or state tax withholding
requirements. Unless further limited by the Committee in any Option, the
exercise price of any Shares purchased pursuant to the exercise of such Option
shall be paid in cash, by certified or official bank check, by money order, with
Shares or by a combination of the above; PROVIDED, HOWEVER, that the Committee
in its sole discretion may accept a personal check in full or partial payment of
any Shares. If the exercise price is paid in whole or in part with Shares, the
value of the Shares surrendered shall be their Fair Market Value on the date the
Option is exercised. The Company in its sole discretion may, on an individual
basis or pursuant to a general program established by the Committee in
connection with this Plan, lend money to an Optionee to exercise all or a
portion of the Option granted hereunder. If the exercise price is paid in whole
or part with the Optionee's promissory note, such note shall (i) provide for
full recourse to the maker, (ii) be collateralized by the pledge of the Shares
that the Optionee purchases upon exercise of such Option, (iii) bear interest at
a rate no less than the rate of interest payable by the Company to its principal
lender, and (iv) contain such other terms as the Committee in its sole
discretion shall require. No Optionee shall be deemed to be a holder of any
shares subject to an Option unless and until a stock certificate or certificates
for such shares are issued to the person(s) under the terms of this Plan. No
adjustments shall be made for dividends (ordinary or extraordinary, whether in
cash, securities or property) or distributions or other rights for which the
record date is prior to the date such stock certificate is issued, except as
expressly provided in Section 10 hereof

                  (b) No Optionee shall be deemed to be a holder of any Shares
subject to an Option unless and until a stock certificate or certificates for
such Shares are issued to such person(s) under the terms of this Plan. No
adjustment shall be made for dividends (ordinary or extraordinary, whether in
cash, securities or other property) or distributions or other rights for which
the record date is prior to the date such stock certificate is issued, except as
expressly provided in Section 10 hereof

         8. EXERCISABILITY OF OPTIONS. Any Option shall become exercisable in
such amounts, at such intervals, upon such events or occurrences and upon such
other terms and conditions as shall be provided in an individual Option
agreement evidencing such Option, except as otherwise provided in Section 5(b)
or this Section 8.

                  (a) The expiration date(s) of an Option shall be determined by
the Committee at the time of grant, but in no event shall an Option be
exercisable after the expiration of 10 years from the date of grant of the
Option.

                  (b) Unless otherwise expressly provided in any Option as
approved by the Committee, notwithstanding the exercise schedule set forth in
any Option, each outstanding Option, may, in the sole discretion of the
Committee, become fully exercisable upon the date of the occurrence of any
Change of Control, but, unless otherwise expressly provided in any Option, no
earlier than six months after the date of grant, and if and only if Optionee is
in the employ of the Company on such date.


                                        6


<PAGE>

                  (c) The Committee may in its sole discretion accelerate the
date on which any Option may be exercised and may accelerate the vesting of any
Shares subject to any Option or previously acquired by the exercise of any
Option.

         9. TERMINATION OF OPTION PERIOD.

                  (a) Unless otherwise expressly provided in any Option, the
unexercised portion of any Option shall automatically and without notice
immediately terminate and become forfeited, null and void at the time of the
earliest to occur of the following:

                             (i)   three months after the date on which the 
Optionee's employment is terminated for any reason other than by reason of (A) 
Cause, (B) the termination of the Optionee's employment with the Company by 
such Optionee following less than ninety (90) days' prior written notice to the 
Company of such termination (an "Improper Termination"), (C) a mental or 
physical disability as determined by a medical doctor satisfactory to the 
Committee, or (D) death;

                            (ii)   immediately upon (A) the termination by the 
Company of the Optionee's employment for Cause, or (B) an Improper Termination;

                           (iii)   one year after the date on which the 
Optionee's employment is terminated by reason of a mental or physical disability
(within the meaning of Code Section 22(e)) as determined by a medical doctor 
satisfactory to the Committee; or

                            (iv)   the later of (A) twelve months after the 
date of termination of the Optionee's employment by reason of death of the 
employee, or (B) three months after the date on which the Optionee shall die if 
such death shall occur during the one year period specified in Subsection 
9(a)(iii) hereof

                  (b) The Committee in its sole discretion may by giving written
notice ("cancellation notice") cancel, effective upon the date of the
consummation of any corporate transaction described in Subsection 10(d) hereof,
any Option that remains unexercised on such date. Such cancellation notice shall
be given a reasonable period of time prior to the proposed date of such
cancellation and may be given either before or after approval of such corporate
transaction.

                  (c) Upon Optionee's termination of employment as described in
this Section 9, or otherwise, any Option (or portion thereof) not previously
vested or not yet exercisable pursuant to Section 8 of this Plan or the vesting
schedule set forth in such Option shall be immediately canceled.

         10. ADJUSTMENT OF SHARES.

                  (a) If at any time while this Plan is in effect or unexercised
Options are outstanding, there shall be any increase or decrease in the number
of issued and outstanding


                                        7


<PAGE>

Shares through the declaration of a stock dividend or through any
recapitalization resulting in a stock split, combination or exchange of Shares
(other than any such exchange or issuance of Shares through which Shares are
issued to effect an acquisition of another business or entity or the Company's
purchase of Shares to exercise a "call" purchase option), then and in such
event:

                             (i)   appropriate adjustment shall be made in the 
maximum number of Shares available for grant under this Plan, so that the same 
percentage of the Company's issued and outstanding Shares shall continue to be 
subject to being so optioned; and

                            (ii)   appropriate adjustment shall be made in the 
number of Shares and the exercise price per Share thereof then subject to any 
outstanding Option, so that the same percentage of the Company's issued and 
outstanding Shares shall remain subject to purchase at the same aggregate 
exercise price.

                           (iii)   Such adjustments shall be made by the 
Committee, whose determination in that respect shall be final, binding and 
conclusive.

                  (b) Subject to the specific terms of any Option, the Committee
may change the terms of Options outstanding under this Plan, with respect to the
option price or the number of Shares subject to the Options, or both, when, in
the Committee's sole discretion, such adjustments become appropriate by reason
of a corporate transaction described in Subsection 10(d) hereof, or otherwise.

                  (c) Except as otherwise expressly provided herein, the
issuance by the Company of shares of its capital stock of any class, or
securities convertible into or exchangeable for shares of its capital stock of
any class, either in connection with a direct or underwritten sale or upon the
exercise of rights or warrants to subscribe therefor or purchase such Shares, or
upon conversion of shares of obligations of the Company convertible into such
shares or other securities, shall not affect, and no adjustment by reason
thereof shall be made with respect to the number of or exercise price of Shares
then subject to outstanding Options granted under this Plan.

                  (d) Without limiting the generality of the foregoing, the
existence of outstanding Options granted under this Plan shall not affect in any
manner the right or power of the Company to make, authorize or consummate (i)
any or all adjustments, reclassifications, recapitalizations, reorganizations or
other changes in the Company's capital structure or its business; (ii) any
merger or consolidation of the Company or to which the Company is a party; (iii)
any issuance by the Company of debt securities, or preferred or preference stock
that would rank senior to or above the Shares subject to outstanding Options;
(iv) any purchase or issuance by the Company of Shares or other classes of
common stock or common equity securities; (v) the dissolution or liquidation of
the Company; (vi) any sale, transfer, encumbrance, pledge or assignment of all
or any part of the assets or business of the Company; or (vii) any other
corporate act or proceeding, whether of a similar character or otherwise.


                                        8


<PAGE>

                  (e) The Optionee shall receive written notice within a
reasonable time prior to the consummation of such action advising the Optionee
of any of the foregoing. The Committee may, in the exercise of its sole
discretion, in such instances declare that any Option shall terminate as of a
date fixed by the Board and give each Optionee the right to exercise his or her
Option.

         11. TRANSFERABILITY OF OPTIONS. No Option granted hereunder shall be
sold, pledged, assigned, hypothecated, disposed or otherwise transferred by the
Optionee other than by will or the laws of descent and distribution, and no
Option shall be exercisable during the Optionee's lifetime by any person other
than the Optionee.

         12. ISSUANCE OF SHARES. As a condition of any sale or issuance of
Shares upon exercise of any Option, the Committee may require such agreements or
undertakings, if any, as the Committee may deem necessary or advisable to assure
compliance with any such law or regulation including, but not limited to, the
following:

                             (i)   a representation and warranty by the Optionee
to the Company, at the time any Option is exercised, that he is acquiring the 
Shares to be issued to him for investment and not with a view to, or for sale in
connection with, the distribution of any such Shares; and

                            (ii)   (A)      an agreement and undertaking to 
comply with all of the terms, restrictions and provisions set forth in any then 
applicable shareholders' agreement relating to the Shares, including, without 
limitation, any restrictions on transferability, any rights of first refusal 
and any option of the Company to "call" or purchase such Shares under then 
applicable agreements, and

                                   (B)      any restrictive legend or legends,
to be embossed or imprinted on Share certificates, that are, in the discretion 
of the Committee, necessary or appropriate to comply with the provisions of any 
securities law or other restriction applicable to the issuance of the Shares.

         13. ADMINISTRATION OF THIS PLAN.

                  (a) This Plan shall be administered by the Committee, which
shall consist of not less than two Directors. The Committee shall have all of
the powers of the Board with respect to this Plan. Any member of the Committee
may be removed at any time, with or without cause, by resolution of the Board
and any vacancy occurring in the membership of the Committee may be filled by

determine the Optionees to whom, and time or times at which, Options shall be
granted, (iv) determine the number of Shares to be represented by each Option,

                                        9


<PAGE>

need not be identical) and, with the consent of the holder thereof, modify or
amend each Option, (vi) defer (with the consent of the Optionee) or accelerate
the exercise date of any Option, and (vii) make all other determinations deemed
necessary or advisable for the administration of this Plan, including repricing,
canceling and regranting Options.

                  (c) The Committee, from time to time, may adopt rules and
regulations for carrying out the purposes of this Plan. The Committee's
determinations and its interpretation and construction of any provision of this
Plan shall be final, conclusive and binding upon all Optionees and any holders
of any Options granted under this Plan.

                  (d) Any and all decisions or determinations of the Committee
shall be made either (i) by a majority vote of the members of the Committee at a
meeting of the Committee or (ii) without a meeting by the unanimous written
approval of the members of the Committee.

                  (e) No Member of the Committee, or any Officer or Director of
the Company or its Subsidiaries, shall be personally liable for any act or
omission made in good faith in connection with this Plan.

         14. INCENTIVE OPTIONS FOR 10% SHAREHOLDERS. Notwithstanding any other
provisions of this Plan to the contrary, an Incentive Stock Option shall not be
granted to any person owning directly or indirectly (through attribution under
Section 424(d) of the Code) at the date of grant, stock possessing more than 10%
of the total combined voting power of all classes of stock of the Company (or of
its Subsidiary) at the date of grant unless the exercise price of such Option is
at least 110% of the Fair Market Value of the Shares subject to such Option on

                              NETSPEAK CORPORATION

                            INDEMNIFICATION AGREEMENT

         THIS INDEMNIFICATION AGREEMENT, dated as of _____ __, 199_, by and
between NetSpeak Corporation, a corporation organized under the laws of the
State of Florida (the "Corporation"), with its principal office located at 902
Clint Moore Road, Suite 104, Boca Raton, Florida 33487, and _____, an individual
with an address at___________________________ (the "Indemnitee").

                              W I T N E S S E T H:

         WHEREAS, the substantial increase in corporate litigation subjects
directors and officers of corporations and others to expensive litigation risks
at the same time that the availability of competent and qualified directors,
officers, employees, consultants, advisers and agents has been greatly reduced,
and the coverage offered by directors' and officers' liability insurance has
been severely limited;

         WHEREAS, Indemnitee does not regard the protection available under the
Corporation's Articles of Incorporation, By-laws and insurance as adequate in
the present circumstances, and may not be willing to serve as a director to the
Corporation without adequate protection, and the Corporation desires Indemnitee
to serve in such capacity;

         WHEREAS, as a condition to the Indemnitee's agreement to continue to
serve as a director of the Corporation, the Indemnitee requires that he be
indemnified from liability to the fullest extent permitted by law; and

         WHEREAS, the Corporation is willing to indemnify the Indemnitee to the
fullest extent permitted by law in order to retain the services of the
Indemnitee.

         NOW, THEREFORE, for and in consideration of the mutual promises and
covenants contained herein, the Corporation and the Indemnitee agree as follows:

         SECTION 1.  MANDATORY INDEMNIFICATION IN PROCEEDINGS OTHER
THAN THOSE BY OR IN THE RIGHT OF THE CORPORATION.  Subject to Section 5
hereof, the Corporation shall indemnify and hold harmless the Indemnitee from
and against any and all claims, damages, expenses (including attorneys' fees),
judgments, penalties, fines (including excise taxes assessed with respect to an
employee benefit plan), settlements, and all other liabilities incurred or paid
by him in connection with the investigation, defense, prosecution, settlement or
appeal of any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative (other than an action
by or in the right of the Corporation) and to which the Indemnitee was or is a
party or is threatened to be made a party by reason of the fact that the
Indemnitee is or was an officer, director,


                                       -1-


<PAGE>

shareholder, employee, consultant adviser or agent of the Corporation, or is or
was serving at the request of the Corporation as an officer, director, partner,
trustee, employee, adviser or agent of another corporation, partnership, joint
venture, trust, employee benefit plan or other enterprise, or by reason of
anything done or not done by the Indemnitee in any such capacity or capacities,
provided that the Indemnitee acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the Corporation, and,
with respect to any criminal action or proceeding, had no reasonable cause to
believe his conduct was unlawful.

         SECTION 2. MANDATORY INDEMNIFICATION IN PROCEEDINGS BY OR IN THE RIGHT
OF THE CORPORATION. Subject to Section 5 hereof the Corporation shall indemnify
and hold harmless the Indemnitee from and against any and all expenses
(including attorneys' fees) and amounts actually and reasonably incurred or paid
by him in connection with the investigation, defense, prosecution, settlement or
appeal of any threatened, pending or completed action, suit or proceeding by or
in the right of the Corporation to procure a judgment in its favor, whether
civil, criminal, administrative or investigative, and to which the Indemnitee
was or is a party or is threatened to be made a party by reason of the fact that
the Indemnitee is or was an officer, director, shareholder, employee,
consultant, adviser or agent of the Corporation, or is or was serving at the
request of the Corporation as an officer, director, partner, trustee, employee,
adviser or agent of another corporation, partnership, joint venture, trust,
employee benefit plan or other enterprise, or by reason of anything done or not
done by the Indemnitee in any such capacity or capacities, provided that (i) the
Indemnitee acted in good faith and in a manner he reasonably believed to be in
or not opposed to the best interests of the Corporation and (ii) no
indemnification shall be made under this Section 2 in respect of any claim,
issue or matter as to which the Indemnitee shall have been adjudged to be liable
to the Corporation for misconduct in the performance of his duty to the
Corporation unless, and only to the extent that, the court in which such
proceeding was brought (or any other court of competent jurisdiction) shall
determine upon application that, despite the adjudication of liability but in
view of all the circumstances of the case, the Indemnitee is fairly and
reasonably entitled to indemnity for such expenses which such court shall deem
proper.

         SECTION 3. MANDATORY INDEMNIFICATION AGAINST EXPENSES INCURRED WHILE
TESTIFYING. Subject to Section 5 hereof, the Corporation shall indemnify the
Indemnitee against expenses (including attorney's fees) incurred or paid by the
Indemnitee as a result of providing testimony in any proceeding, whether civil,
criminal, administrative or investigative (including but not limited to any
action or suit by or in the right of the Corporation to procure judgment in its
favor), by reason of the fact that the Indemnitee is or was an officer,
director, shareholder, employee, consultant, adviser or agent of the
Corporation, or is or was serving at the request of the Corporation as an
officer, director, partner, trustee, employee, adviser or agent of another
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise.

         SECTION 4.  REIMBURSEMENT OF EXPENSES FOLLOWING ADJUDICATION
OF NEGLIGENCE.  The Corporation shall reimburse the Indemnitee for any expenses
(including attorney's fees) and amounts actually and reasonably incurred or paid
by him in


                                       -2-


<PAGE>

connection with the investigation, defense, settlement or appeal of any action
or suit described in Section 2 hereof that results in an adjudication that the
Indemnitee was liable for negligence, gross negligence or recklessness (but not
willful misconduct) in the performance of his duty to the Corporation; provided,
however, that the Indemnitee acted in good faith and in a manner he believed to
be in the best interests of the Corporation.

         SECTION 5. AUTHORIZATION OF INDEMNIFICATION. Any indemnification under
Sections 1, 2 and 3 hereof (unless ordered by a court) and any reimbursement
made under Section 4 hereof shall be made by the Corporation only as authorized
in the specific case upon a determination (the "Determination") that
indemnification or reimbursement of the Indemnitee is proper in the
circumstances because the Indemnitee has met the applicable requirements set
forth in Section 1, 2, 3 and 4 hereof, as the case may be. Subject to Sections
6.6, 6.7 and 9 of this Agreement, the Determination shall be made in the
following order of preference:

                           (1)      first, by the Corporation's Board of 
Directors (the "Board") by majority vote or consent of a quorum consisting of 
directors ("Disinterested Directors") who are not, at the time of the 
Determination, named parties to such action, suit or proceeding; or

                           (2)      next, if such a quorum of Disinterested 
Directors cannot be obtained, by majority vote or consent of a committee duly 
designated by the Board (in which designation all directors, whether or not 
Disinterested Directors, may participate) consisting solely of two or more 
Disinterested Directors; or

                           (3)      next, if such a committee cannot be 
designated, by any independent legal counsel (who may be any outside counsel 
regularly employed by the Corporation) in a written opinion; or

                           (4)      next, if such legal counsel determination 
cannot be obtained, by vote or consent of the holders of a majority of the 
Corporation's common stock.

         5.1 NO PRESUMPTIONS. The termination of any action, suit or proceeding
by judgment, order, settlement, conviction, or upon a plea of NOLO CONTENDERE or
its equivalent, shall not, of itself, create a presumption that the Indemnitee
did not act in good faith and in a manner that he reasonably believed to be in
or not opposed to the best interests of the Corporation, and with respect to any
criminal action or proceeding, had reasonable cause to believe that his conduct
was unlawful.

         5.2 BENEFIT PLAN CONDUCT. The Indemnitee's conduct with respect to an
employee benefit plan for a purpose he reasonably believed to be in the
interests of the participants in and beneficiaries of the plan shall be deemed
to be conduct that the Indemnitee reasonably believed to be not opposed to the
best interests of the Corporation.

         5.3 RELIANCE AS SAFE HARBOR.  For purposes of any Determination 
hereunder, the Indemnitee shall be deemed to have acted in good faith and in a 
manner he reasonably believed


                                       -3-


<PAGE>

to be in or not opposed to the best interests of the Corporation, or, with
respect to any criminal action or proceeding, to have had no reasonable cause to
believe his conduct was unlawful, if his action is based on (i) the records or
books of account of the Corporation or another enterprise, including financial
statements, (ii) information supplied to him by the officers of the Corporation
or another enterprise in the course of their duties, (iii) the advice of legal
counsel for the Corporation or another enterprise, or (iv) information or
records given or reports made to the Corporation or another enterprise by an
independent certified public accountant or by an appraiser or other expert
selected with reasonable care by the Corporation or another enterprise. The term
"another enterprise" as used in this Section 5.3 shall mean any other
corporation or any partnership, joint venture, trust, employee benefit plan or
other enterprise of which the Indemnitee is or was serving at the request of the
Corporation as an officer, director, partner, trustee, employee, adviser or
agent. The provisions of this Section 5.3 shall not be deemed to be exclusive or
to limit in any way the other circumstances in which the Indemnitee may be
deemed to have met the applicable standard of conduct set forth in Sections 1, 2
or 4 hereof, as the case may be.

         5.4 SUCCESS ON MERITS OR OTHERWISE. Notwithstanding any other provision
of this Agreement, to the extent that the Indemnitee has been successful on the
merits or otherwise in defense of any action, suit or proceeding described in
Section 1 or 2 hereof, or in defense of any claim, issue or matter therein, he
shall be indemnified against expenses (including attorneys' fees) actually and
reasonably incurred by him in connection with the investigation, defense,
settlement or appeal thereof. For purposes of this Section 5.4, the term
"successful on the merits or otherwise" shall include, but not be limited to,
(i) any termination, withdrawal, or dismissal (with or without prejudice) of any
claim, action, suit or proceeding against the Indemnitee without any express
finding of liability or guilt against him, and (ii) the expiration of 120 days
after the making of any claim or threat of an action, suit or proceeding without
the institution of the same and without any promise or payment made to induce a
settlement.

         5.5 PARTIAL INDEMNIFICATION OR REIMBURSEMENT. If the Indemnitee is
entitled under any provision of this Agreement to indemnification and/or
reimbursement by the Corporation for some or a portion of the claims, damages,
expenses (including attorneys' fees), judgments, penalties, fines or amounts
paid in settlement by the Indemnitee in connection with the investigation of,
defense of, settlement of, appeal of or testimony provided with respect to any
action specified in Section 1, 2, or 3 hereof, but not, however, for the total
amount thereof, the Corporation shall nevertheless indemnify and/or reimburse
the Indemnitee for the portion thereof to which the Indemnitee is entitled. The
party or parties making the Determination shall determine the portion (if less
than all) of such claims, damages, expenses (including attorneys' fees),
judgments, penalties, fines or amounts paid in settlement for which the
Indemnitee is entitled to indemnification and/or reimbursement under this
Agreement.


                                      -4-


<PAGE>

         SECTION 6.  PROCEDURES FOR DETERMINATION OF WHETHER STANDARDS
HAVE BEEN SATISFIED.

         6.1 COSTS. All costs of making the Determination required by Section 6
hereof shall be borne solely by the Corporation, including, but not limited to,
the costs of legal counsel, proxy solicitations and judicial determinations. The
Corporation shall also be solely responsible for paying (i) all reasonable
expenses incurred by the Indemnitee to enforce this Agreement, including, but
not limited to, the costs incurred by the Indemnitee to obtain court-ordered
indemnification pursuant to Section 9 hereof regardless of the outcome of any
such application or proceeding, and (ii) all costs of defending any suits or
proceedings challenging payments to the Indemnitee under this Agreement.

         6.2 TIMING OF THE DETERMINATION.  The Corporation shall use its 
best efforts to make the Determination contemplated by Section 5 hereof 
promptly.  In addition, the Corporation agrees:

                  (a) if the Determination is to be made by the Board or a
committee thereof, such Determination shall be made not later than 15 days after
a written request for a Determination (a "Request") is delivered to the
Corporation by the Indemnitee;

                  (b) if the Determination is to be made by independent legal
counsel, such Determination shall be made not later than 30 days after a Request
is delivered to the Corporation by the Indemnitee; and

                  (c) if the Determination is to be made by the shareholders of
the Corporation, such Determination shall be made not later than 90 days after a
Request is delivered to the Corporation by the Indemnitee.

The failure to make a Determination within the above-specified time period shall
constitute a Determination approving full indemnification or reimbursement of
the Indemnitee. Notwithstanding anything herein to the contrary, a Determination
may be made in advance of (i) the Indemnitee's payment (or incurring) of
expenses with respect to which indemnification or reimbursement is sought,
and/or (ii) final disposition of the action, suit or proceeding with respect to
which indemnification or reimbursement is sought.

         6.3 REASONABLENESS OF EXPENSES. The evaluation and finding as to the
reasonableness of expenses incurred by the Indemnitee for purposes of this
Agreement shall be made (in the following order of preference) within 15 days of
the Indemnitee's delivery to the Corporation of a Request that includes a
reasonable accounting of expenses incurred:

                  (a) first, by the Board by a majority vote of a quorum 
consisting of Disinterested Directors; or


                                       -5-


<PAGE>

                  (b) next, if a quorum cannot be obtained under subdivision
(a), by majority vote or consent of a committee duly designated by the Board (in
which designation all directors, whether or not Disinterested Directors, may
participate), consisting solely of two or more Disinterested Directors; or

                  (c) next, if a finding cannot be obtained under either
subdivision (a) or (b), by vote or consent of the holders of a majority of the
Corporation's Common Stock that are represented in person or by proxy at a
meeting called for such purpose.

All expenses shall be considered reasonable for purposes of this Agreement if
the finding contemplated by this Section 6.3 is not made within the prescribed
time. The finding required by this Section 6.3 may be made in advance of the
payment (or incurring) of the expenses for which indemnification or
reimbursement is sought.

         6.4 PAYMENT OF INDEMNIFIED AMOUNT. Immediately following a
Determination that the Indemnitee has met the applicable requirements set forth
in Section 1, 2, 3 or 4 hereof, as the case may be, and the finding of
reasonableness of expenses contemplated by Section 6.3 hereof, or the passage of
time prescribed for making such determination(s), the Corporation shall pay to
the Indemnitee in cash the amount to which the Indemnitee is entitled to be
indemnified and/or reimbursed, as the case may be, without further authorization
or action by the Board; provided, however, that the expenses for which
indemnification or reimbursement is sought have actually been incurred by the
Indemnitee.

         6.5 SHAREHOLDER VOTE ON DETERMINATION. Notwithstanding the provisions
of the Florida statutes, if the Indemnitee is a shareholder of the Corporation,
the Indemnitee and any other shareholder who is a party to the proceeding for
which indemnification or reimbursement is sought shall be entitled to vote on
any Determination to be made by the Corporation's shareholders, including a
Determination made pursuant to Section 6.3 hereof. In addition, in connection
with each meeting at which a shareholder Determination will be made, the
Corporation shall solicit proxies that expressly include a proposal to indemnify
or reimburse the Indemnitee. The Corporation proxy statement relating to the
proposal to indemnify or reimburse the Indemnitee shall not include a
recommendation against indemnification or reimbursement.

         6.6 SELECTION OF INDEPENDENT LEGAL COUNSEL. If the Determination
required under Section 5 is to be made by independent legal counsel, such
counsel shall be selected by the Indemnitee with the approval of the Board,
which approval shall not be unreasonably withheld. The fees and expenses
incurred by counsel in making any Determination (including Determinations
pursuant to Section 6.8 hereof) shall be borne solely by the Corporation
regardless of the results of any Determination and, if requested by counsel, the
Corporation shall give such counsel an appropriate written agreement with
respect to the payment of their fees and expenses and such other matters as may
be reasonably requested by counsel.

         6.7 RIGHT OF INDEMNITEE TO APPEAL AN ADVERSE DETERMINATION BY BOARD. If
a Determination is made by the Board or a committee thereof that the Indemnitee
did not meet the


                                       -6-


<PAGE>

requirements set forth in Section 1, 2, 3 or 4 hereof upon the written request
of the Indemnitee and the Indemnitee's delivery of $500 to the Corporation, the
Corporation shall cause a new Determination to be made by the Corporation's
shareholders at the next regular or special meeting of shareholders. Subject to
Section 9 hereof, such Determination by the Corporation's shareholders shall be
binding and conclusive for all purposes of this Agreement.

         6.8 RIGHT OF INDEMNITEE TO SELECT FORUM FOR DETERMINATION. If, at any
time subsequent to the date of this Agreement, "Continuing Directors" do not
constitute a majority of the members of the Board, or there is otherwise a
change in control of the Corporation (as contemplated by Item 403(c) of
Regulation S-K), then upon the request of the Indemnitee, the Corporation shall
cause the Determination required by Section 5 hereof to be made by independent
legal counsel selected by the Indemnitee and approved by the Board (which
approval shall not be unreasonably withheld), which counsel shall be deemed to
satisfy the requirements of clause (3) of Section 5 hereof. If none of the legal
counsel selected by the Indemnitee are willing and/or able to make the
Determination, then the Corporation shall cause the Determination to be made by
a majority vote or consent of a Board committee consisting solely of Continuing
Directors. For purposes of this Agreement, a "Continuing Director" means either
a member of the Board at the date of this Agreement or a person nominated to
serve as a member of the Board by a majority of the then Continuing Directors.

         6.9 ACCESS BY INDEMNITEE TO DETERMINATION. The Corporation shall afford
to the Indemnitee and his representatives ample opportunity to present evidence
of the facts upon which the Indemnitee relies for indemnification or
reimbursement, together with other information relating to any requested
Determination. The Corporation shall also afford the Indemnitee the reasonable
opportunity to include such evidence and information in any Corporation proxy
statement relating to a shareholder Determination.

         6.10 JUDICIAL DETERMINATIONS IN DERIVATIVE SUITS. In each action or
suit described in Section 2 hereof, the Corporation shall cause its counsel to
use its best efforts to obtain from the Court in which such action or suit was
brought (i) an express adjudication whether the Indemnitee is liable for
negligence or misconduct in the performance of his duty to the Corporation, and,
if the Indemnitee is so liable, (ii) a determination whether and to what extent,
despite the adjudication of liability but in view of all the circumstances of
the case (including this Agreement), the Indemnitee is fairly and reasonably
entitled to indemnification.

         SECTION 7. SCOPE OF INDEMNITY. The actions, suits and proceedings
described in Sections 1 and 2 hereof shall include, for purposes of this
Agreement, any actions that involve, directly or indirectly, activities of the
Indemnitee both in his capacities as a Corporation director, officer, adviser or
agent and actions taken in another capacity while serving as director, officer,
adviser or agent, including, but not limited to, actions or proceedings
involving (i) compensation paid to the Indemnitee by the Corporation, (ii)
activities by the Indemnitee on behalf of the Corporation, including actions in
which the Indemnitee is plaintiff, (iii) actions alleging a misappropriation of
a 'corporate opportunity," (iv) responses to a takeover attempt or threatened
takeover attempt of the Corporation, (v) transactions by the Indemnitee in


                                       -7-


<PAGE>

Corporation securities, and (vi) the Indemnitee's preparation for and appearance
(or potential appearance) as a witness in any proceeding relating, directly or
indirectly, to the Corporation. In addition, the Corporation agrees that, for
purposes of this Agreement, all services performed by the Indemnitee on behalf
of, in connection with or related to any subsidiary of the Corporation, any
employee benefit plan established for the benefit of employees of the
Corporation or any subsidiary, any corporation or partnership or other entity in
which the Corporation or any subsidiary has a 5% ownership interest, or any
other affiliate shall be deemed to be at the request of the Corporation.

         SECTION 8.  ADVANCE FOR EXPENSES.

         8.1 MANDATORY ADVANCE. Expenses (including attorneys' fees) incurred by
the Indemnitee in investigating, defending, settling or appealing any action,
suit or proceeding described in Section 1 or 2 hereof shall be paid by the
Corporation in advance of the final disposition of such action, suit or
proceeding. The Corporation shall promptly pay the amount of such expenses to
the Indemnitee, but in no event later than 10 days following the Indemnitee's
delivery to the Corporation of a written request for an advance pursuant to this
Section 8, together with a reasonable accounting of such expenses.

         8.2 UNDERTAKING TO REPAY. The Indemnitee hereby undertakes and agrees
to repay to the Corporation any advances made pursuant to this Section 8 if and
to the extent that it shall ultimately be found that the Indemnitee is not
entitled to be indemnified by the Corporation for such amounts.

         8.3 MISCELLANEOUS. The Corporation shall make the advances contemplated
by this Section 8 regardless of the Indemnitee's financial ability to make
repayment, and regardless whether indemnification of the Indemnitee by the
Corporation will ultimately be required. Any advances and undertakings to repay
pursuant to this Section 8 shall be unsecured and interest-free.

         SECTION 9.  COURT-ORDERED INDEMNIFICATION.

         9.1 Regardless whether the Indemnitee has met the requirements set
forth in Sections 1, 2, 3 or 4 hereof, as the case may be, and notwithstanding
the presence or absence of any Determination whether such standards have been
satisfied, the Indemnitee may apply for indemnification (and/or reimbursement
pursuant to Section 4 or 13 hereto to the court conducting any proceeding to
which the Indemnitee is a party or to any other court of competent jurisdiction.
On receipt of an application, the court, after giving any notice the court
considers necessary, may order indemnification (and/or reimbursement) if it
determines the Indemnitee is fairly and reasonably entitled to indemnification
(and/or reimbursement) in view of all the relevant circumstances (including this
Agreement).

         9.2 The right to indemnification and advances as provided by this 
Agreement shall be enforceable by Indemnitee in an action in any court of 
competent jurisdiction.  In such an


                                       -8-


<PAGE>

action, the burden of proving that indemnification is not required hereunder
shall be on the Corporation. Neither the failure of the Corporation (including
its Board and independent legal counsel) to have made a Determination prior to
the commencement of such an action that indemnification is proper in the
circumstances because Indemnitee has met the applicable standard of conduct, nor
an actual Determination by the Corporation (including its Board and independent
legal counsel) that Indemnitee has not met such applicable standard of conduct,
shall be a defense to such an action or create a presumption that Indemnitee has
not met the applicable standard of conduct. Indemnitee's expenses reasonably
incurred in connection with establishing his right to indemnification, in whole
or in part, in connection with any proceeding shall also be indemnified by the
Corporation.

         SECTION 10. NONDISCLOSURE OF PAYMENTS. Except as expressly required by
Federal securities laws, neither party shall disclose any payments under this
Agreement unless prior approval of the other party is obtained. Any payments to
the Indemnitee that must be disclosed shall, unless otherwise required by law,
be described only in Corporation proxy or information statements relating to
special and/or annual meetings of the Corporation's shareholders, and the
Corporation shall afford the Indemnitee the reasonable opportunity to review all
such disclosures and, if requested, to explain in such statement any mitigating
circumstances regarding the events reported.

         SECTION 11. COVENANT NOT TO SUE, LIMITATION OF ACTIONS AND RELEASE OF
CLAIMS. No legal action shall be brought and no cause of action shall be
asserted by or on behalf of the Corporation (or any of its subsidiaries) against
the Indemnitee, his spouse, heirs, executors, personal representatives or
administrators after the expiration of 2 years from the date the Indemnitee
ceases (for any reason) to serve as either an officer, director, adviser or
agent of the Corporation, and any claim or cause of action of the Corporation
(or any of its subsidiaries) shall be extinguished and deemed released unless
asserted by filing of a legal action within such 2-year period.

         SECTION 12. INDEMNIFICATION OF INDEMNITEE'S ESTATE. Notwithstanding any
other provision of this Agreement, if the Indemnitee is deceased, and
indemnification of the Indemnitee would be permitted and/or required under this
Agreement, the Corporation shall indemnify and hold harmless the Indemnitee's
estate, spouse, heirs, administrators, personal representatives and executors
(collectively the "Indemnitee's Estate") against, and the Corporation shall
assume, any and all claims, damages, expenses (including attorneys' fees),
penalties, judgments, fines and amounts paid in settlement actually incurred by
the Indemnitee or the Indemnitee's Estate in connection with the investigation,

                               EMPLOYMENT AGREEMENT

THIS EMPLOYMENT AGREEMENT ("Agreement") is made and entered into as of this 1st

                  Executive Officer of the Company.

         2.       The Executive possesses intimate knowledge of the business and
                  affairs of the Company, its policies, methods and personnel.

         3.       The Board of Directors (the "Board") of the Company recognizes
                  that the Executive's contribution, as Chairman of the Board
                  and Chief Executive Officer of the Company, to the growth and
                  success of the Company has been and will be substantial and
                  desires to assure the Company of the Executive's present and
                  continued employment in an executive capacity and to
                  compensate him therefore.

         4.       The Board has determined that this Agreement will reinforce 
                  and encourage the Executive's continued attention and
                  dedication to the Company.

         5.       The Executive is willing to make his services available to the
                  Company on the terms and conditions hereinafter set forth.

                           between the Executive and the Company.

         4.       TERMINATION.

                  4.1      TERMINATION FOR CAUSE. Notwithstanding anything
                           contained in this Agreement to the contrary, this
                           Agreement may be terminated by the Company for Cause.
                           As used in the Agreement, "Cause" shall only mean (i)
                           subject to the following sentences, any action or
                           omission of the Executive which constitutes a willful
                           and material breach of this Agreement which is not
                           cured or as to which diligent attempts to cure have
                           not commenced within 30 business days after receipt
                           by Executive of notice of same, (ii) fraud,
                           embezzlement or misappropriation as against the
                           Company, or (iii) the conviction (from which no
                           appeal can be taken) of Executive for any criminal
                           act which is a felony. Upon any determination by the
                           Company's Board of Directors that Cause exists under
                           clause (i) of the preceding sentence, the Company
                           shall cause a special meeting of the Board to be
                           called and held at a time mutually convenient to the
                           Board and the Executive, but in no event later than
                           10 business days after Executive's receipt of the
                           notice contemplated by clause (i). Executive shall
                           have the right to appear before such special meeting
                           of the Board with legal counsel of his choosing to
                           refute any determination of Cause specified in such
                           notice, and termination of Executive's employment by
                           reason of such Cause specified in such notice, and
                           any termination of Executive's employment by reason
                           of such Cause determination shall not be effective
                           until Executive is afforded such opportunity to
                           appear. Any termination for Cause pursuant to clause
                           (ii) or (iii) of this Paragraph 4.1 shall be made in
                           writing to Executive, which notice shall set forth in
                           detail all acts or omissions upon which the Company
                           is relying for such termination. Upon any termination
                           pursuant to this Paragraph 4.1, the Company shall pay
                           to the Executive any unpaid Base Salary accrued
                           through the effective date of termination specified
                           in such notice. In addition, the Company shall pay
                           any benefits, if any, owed to Executive under any
                           plan provided for Executive under Paragraph 3 hereof
                           in accordance with the terms of such plan as in
                           effect on the date of termination of employment under
                           this paragraph 4.1. Except as provided above, the
                           Company shall have no further liability hereunder
                           (other than for reimbursement for reasonable business
                           expenses incurred prior to the date of termination,
                           subject, however, to the provisions of Paragraph 3.1
                           hereof).

                  4.2      DISABILITY. Notwithstanding anything to the contrary
                           contained in this Agreement if, during the Term
                           hereof the Executive suffers a disability (as defined
                           below) the Company shall, subject to the provisions
                           of Paragraph 4.3 hereof continue to pay Executive the
                           compensation provided in Paragraphs 2.1

                           provided, however, that, in the event Executive is
                           disabled for a period of more than 180 days in any 12
                           month period (The "Disability Period"), the Company
                           may, at its election, by a vote of 75% of the members
                           of the Boards of Directors within 90 days from the
                           end of the Disability Period, terminate this
                           Agreement. In the event of such termination, (a)
                           payment of the Executive's Base Salary at the rate
                           prevailing on the date of termination of the
                           Executive and fringe benefits (to the extent
                           permissible by applicable law) shall be continued for
                           a period of 12 months after such termination and (b)
                           Executive shall receive a bonus, equal to the amount
                           of bonus paid to the Executive during the 12 months
                           preceding the date of termination of the Executive.
                           As used in this Agreement, the term "disability"
                           shall mean the complete inability of Executive to
                           perform his duties under this Agreement as determined
                           by an independent physician selected with the
                           approval of the Company and the Executive. Except as
                           provided above, the Company shall have no further
                           liability hereunder (other than for reimbursement for
                           reasonable business expenses incurred prior to the
                           date of termination subject, however, to the
                           provisions of Paragraph 3.1 hereof).

                  4.3      DEATH. In the event of the death of Executive during
                           the Term of this Agreement, the Company shall pay to
                           Executive's legal representative, any unpaid Base
                           Salary accrued through the date of his death plus a
                           bonus in an amount equal to the amount of bonus paid
                           in the 12 months preceding the date of death of the
                           Executive. Except as provided above, the Company
                           shall have no further liability hereunder (other than
                           for reimbursement for reasonable business expenses
                           incurred prior to the date of the Executive's death,
                           subject, however to the provisions of Paragraph 3.1
                           hereof).

         5.       MITIGATION.  In no event shall the Executive be obligated to 
                  seek other employment or take any other action by way of
                  mitigation of the amounts payable to the Executive under any
                  of the provisions of this Agreement.

         6.       CHANGE IN CONTROL.

                  (a)      For the purposes of this Agreement, a "Change of
                           Control" shall be deemed to have taken place if : (i)
                           any person, including a "group" as defined in Section
                           13(d)(3) of the Securities Exchange Act of 1934, as
                           amended, becomes the owner or beneficial owner of
                           Company securities, after the date of this Agreement,
                           having 20% or more of the combined voting power of
                           the then outstanding securities of the Company that
                           may be cast for the election of directors of the
                           Company (other than as a result of an issuance of
                           securities initiated by the Company, or open market
                           purchases approved by the Board, as long as the
                           majority of the Board approving the purchases is the
                           majority at the time the purchases are made), or (ii)
                           the persons who were directors of the Company before
                           such transactions shall cease to constitute a
                           majority of the Board of the Company, or any
                           successor to the Company, as the direct or indirect
                           result of or in connection with, any cash tender or
                           exchange offer, merger or other business combination,
                           sale of assets or contested election, or any

                           combination of the foregoing transaction. For Change
                           of Control purposes, if the company is a private
                           entity, then the trigger on change of control would
                           be the ownership, beneficially or otherwise, of 50%
                           of the voting securities.

                  (b)      The Company and Executive hereby agree that, if 
                           Executive is affiliated with the Company on the date
                           on which a Change of control occurs, (the "Change of
                           Control Date"), the Company (or, if Executive is
                           affiliated with a subsidiary, the subsidiary) will
                           continue to retain Executive and Executive will
                           remain affiliated with the Company (or subsidiary)
                           for the period commencing on the Change of Control
                           Date and ending on the second anniversary of such
                           date, to exercise such authority and perform such
                           executive duties as are commensurate with the
                           authority being exercised and duties being performed
                           by the Executive immediately prior to the Change of
                           Control Date. If after the Change of Control
                           Executive is requested, and, in his sole and absolute
                           discretion, consents to change his principal business
                           location, the Company will reimburse the Executive
                           for his reasonable relocation expenses, including,
                           without limitation, moving expenses, temporary living
                           and travel expenses for a reasonable time while
                           arranging to move his residence to the changed
                           location, closing costs, if any, associated with the
                           sale of his existing residence and the purchase of a
                           replacement residence at the changed location, plus
                           an additional amount representing a gross-up of any
                           state or federal taxes payable by Executive as a
                           result of any such reimbursement. If the Executive
                           shall not consent to change his business location,
                           the Executive may continue to provide the services
                           required of him hereunder from his then residence
                           and/or business address, and the Company shall
                           continue to maintain an office for Executive at that
                           location commensurate with the Company's office prior
                           to the Change of Control Date.

                  (c)      During the remaining term hereof after the Change of
                           Control Date, the Company (or subsidiary) will (i)
                           continue to pay Executive a salary at not less than
                           the level applicable to Executive on the Change of
                           Control Date, (ii) pay Executive bonuses in amounts
                           not less in amount than those paid during the twelve
                           month period preceding the Change of Control Date,
                           and (iii) continue employee benefit programs as to
                           Executive at levels in effect on the Change of
                           Control Date (but subject to such reductions as may
                           be required to maintain such plans in compliance with
                           applicable federal law regulating employee benefit
                           programs).

                  (d)      If during the remaining term hereof after the Change
                           of Control Date (i) Executive's employment is
                           terminated by the Company (or subsidiary), or (ii)
                           there shall have occurred a material reduction in
                           Executive's compensation or employment related
                           benefits, or a material change in Executive's status,
                           working conditions, management responsibilities or
                           titles, and Executive voluntarily terminates his
                           relationship with the Company within 60 days of any
                           such occurrence, or the last in a series of
                           occurrences, then Executive shall be entitled to
                           receive, subject to the provisions of subparagraphs
                           (e) and (f) below, a lump sum payment equal to 200%
                           of Executive's "base period income" as determined
                           under (e) below. Such amount will be paid to
                           Executive within 15 business days

                           Company.

                  (e)      The Executive's "base period income" shall be his
                           base salary and annual incentive bonuses paid or
                           payable to him during or with respect to the twelve

                           affiliation. If Executive has not been affiliated for
                           twelve months at the time of his termination of
                           affiliation, his "base period income" shall be his
                           annualized base salary at the rate then in effect and
                           any annual incentive bonus paid to Executive prior to
                           the date of his termination of affiliation or payable
                           to Executive with respect to his period of

                  (f)      In the event of a proposed Change in Control, the
                           Company will allow Executive to participate in all
                           meetings and negotiations related thereto.

                  affiliates, associates, partners or agents, either directly or
                  indirectly, and that such right to injunction shall be

                               EMPLOYMENT AGREEMENT

THIS EMPLOYMENT AGREEMENT ("Agreement") is made and entered into as of this 1st

                                    RECITALS

         1.       The Executive is currently the President and Chief Operating
                  Officer of the Company.

         2.       The Executive possesses intimate knowledge of the business and
                  affairs of the Company, its policies, methods and personnel.

         3.       The Board of Directors (the "Board") of the Company recognizes
                  that the Executive's contribution, as President and Chief
                  Operating Officer of the Company, to the growth and success of
                  the Company has been and will be substantial and desires to
                  assure the Company of the Executive's present and continued
                  employment in an executive capacity and to compensate him
                  therefore.

         4.       The Board has determined that this Agreement will reinforce
                  and encourage the Executive's continued attention and
                  dedication to the Company.

         5.       The Executive is willing to make his services available to the
                  Company on the terms and conditions hereinafter set forth.

                           between the Executive and the Company.

         4.       TERMINATION.

                  4.1      TERMINATION FOR CAUSE. Notwithstanding anything
                           contained in this Agreement to the contrary, this
                           Agreement may be terminated by the Company for Cause.
                           As used in the Agreement, "Cause" shall only mean (i)
                           subject to the following sentences, any action or
                           omission of the Executive which constitutes a willful
                           and material breach of this Agreement which is not
                           cured or as to which diligent attempts to cure have
                           not commenced within 30 business days after receipt
                           by Executive of notice of same, (ii) fraud,
                           embezzlement or misappropriation as against the
                           Company, or (iii) the conviction (from which no
                           appeal can be taken) of Executive for any criminal
                           act which is a felony. Upon any determination by the
                           Company's Board of Directors that Cause exists under
                           clause (i) of the preceding sentence, the Company
                           shall cause a special meeting of the Board to be
                           called and held at a time mutually convenient to the
                           Board and the Executive, but in no event later than
                           10 business days after Executive's receipt of the
                           notice contemplated by clause (i). Executive shall
                           have the right to appear before such special meeting
                           of the Board with legal counsel of his choosing to
                           refute any determination of Cause specified in such
                           notice, and termination of Executive's employment by
                           reason of such Cause specified in such notice, and
                           any termination of Executive's employment by reason
                           of such Cause determination shall not be effective
                           until Executive is afforded such opportunity to
                           appear. Any termination for Cause pursuant to clause
                           (ii) or (iii) of this Paragraph 4.1 shall be made in
                           writing to Executive, which notice shall set forth in
                           detail all acts or omissions upon which the Company
                           is relying for such termination. Upon any termination
                           pursuant to this Paragraph 4.1, the Company shall pay
                           to the Executive any unpaid Base Salary accrued
                           through the effective date of termination specified
                           in such notice. In addition, the Company shall pay
                           any benefits, if any, owed to Executive under any
                           plan provided for Executive under Paragraph 3 hereof
                           in accordance with the terms of such plan as in
                           effect on the date of termination of employment under
                           this paragraph 4.1. Except as provided above, the
                           Company shall have no further liability hereunder
                           (other than for reimbursement for reasonable business
                           expenses incurred prior to the date of termination,
                           subject, however, to the provisions of Paragraph 3.1
                           hereof).

                  4.2      DISABILITY. Notwithstanding anything to the contrary
                           contained in this Agreement if, during the Term
                           hereof the Executive suffers a disability (as defined
                           below) the Company shall, subject to the provisions
                           of Paragraph 4.3 hereof continue to pay Executive the
                           compensation provided in Paragraphs 2.1 and 2.2
                           hereof during the period of his disability, provided,
                           however, that, in the event Executive is disabled for
                           a period of more than 180 days in any 12 month period
                           (The "Disability Period"), the Company may, at its
                           election, by a vote of 75% of the members of the

                           such termination and (b) Executive shall receive a
                           bonus, equal to the amount of bonus paid to the
                           Executive during the 12 months preceding the date of
                           termination of the Executive. As used in this
                           Agreement, the term "disability" shall mean the
                           complete inability of Executive to perform his duties
                           under this Agreement as determined by an independent
                           physician selected with the approval of the Company
                           and the Executive. Except as provided above, the
                           Company shall have no further liability hereunder
                           (other than for reimbursement for reasonable business
                           expenses incurred prior to the date of termination
                           subject, however, to the provisions of Paragraph 3.1
                           hereof).

                  4.3      DEATH. In the event of the death of Executive during
                           the Term of this Agreement, the Company shall pay to
                           Executive's legal representative, any unpaid Base
                           Salary accrued through the date of his death plus a
                           bonus in an amount equal to the amount of bonus paid
                           in the 12 months preceding the date of death of the
                           Executive. Except as provided above, the Company
                           shall have no further liability hereunder (other than
                           for reimbursement for reasonable business expenses
                           incurred prior to the date of the Executive's death,
                           subject, however to the provisions of Paragraph 3.1
                           hereof).

         5.       MITIGATION.  In no event shall the Executive be obligated to 
                  seek other employment or take any other action by way of
                  mitigation of the amounts payable to the Executive under any
                  of the provisions of this Agreement.

         6.       CHANGE IN CONTROL.

                  (a)      For the purposes of this Agreement, a "Change of
                           Control" shall be deemed to have taken place if : (i)
                           any person, including a "group" as defined in Section
                           13(d)(3) of the Securities Exchange Act of 1934, as
                           amended, becomes the owner or beneficial owner of
                           Company securities, after the date of this Agreement,
                           having 20% or more of the combined voting power of
                           the then outstanding securities of the Company that
                           may be cast for the election of directors of the
                           Company (other than as a result of an issuance of
                           securities initiated by the Company, or open market
                           purchases approved by the Board, as long as the
                           majority of the Board approving the purchases is the
                           majority at the time the purchases are made), or (ii)
                           the persons who were directors of the Company before
                           such transactions shall cease to constitute a
                           majority of the Board of the Company, or any
                           successor to the Company, as the direct or indirect
                           result of or in connection with, any cash tender or
                           exchange offer, merger or other business combination,
                           sale of assets or contested election, or any
                           combination of the foregoing transaction. For Change
                           of Control purposes, if the company is a private
                           entity, then the trigger on change of control would
                           be the ownership, beneficially or otherwise, of 50%
                           of the voting securities.

                  (b)      The Company and Executive hereby agree that, if
                           Executive is affiliated with the Company on the date
                           on which a Change of control occurs, (the "Change of
                           Control Date"), the Company (or, if Executive is
                           affiliated with a subsidiary, the subsidiary) will
                           continue to retain Executive and Executive will
                           remain affiliated

                           with the Company (or subsidiary) for the period
                           commencing on the Change of Control Date and ending
                           on the second anniversary of such date, to exercise
                           such authority and perform such executive duties as
                           are commensurate with the authority being exercised
                           and duties being performed by the Executive
                           immediately prior to the Change of Control Date. If
                           after the Change of Control Executive is requested,
                           and, in his sole and absolute discretion, consents to
                           change his principal business location, the Company
                           will reimburse the Executive for his reasonable
                           relocation expenses, including, without limitation,
                           moving expenses, temporary living and travel expenses
                           for a reasonable time while arranging to move his
                           residence to the changed location, closing costs, if
                           any, associated with the sale of his existing
                           residence and the purchase of a replacement residence
                           at the changed location, plus an additional amount
                           representing a gross-up of any state or federal taxes
                           payable by Executive as a result of any such
                           reimbursement. If the Executive shall not consent to
                           change his business location, the Executive may
                           continue to provide the services required of him
                           hereunder from his then residence and/or business
                           address, and the Company shall continue to maintain
                           an office for Executive at that location commensurate
                           with the Company's office prior to the Change of
                           Control Date.

                  (c)      During the remaining term hereof after the Change of
                           Control Date, the Company (or subsidiary) will (i)
                           continue to pay Executive a salary at not less than
                           the level applicable to Executive on the Change of
                           Control Date, (ii) pay Executive bonuses in amounts
                           not less in amount than those paid during the twelve
                           month period preceding the Change of Control Date,
                           and (iii) continue employee benefit programs as to
                           Executive at levels in effect on the Change of
                           Control Date (but subject to such reductions as may
                           be required to maintain such plans in compliance with
                           applicable federal law regulating employee benefit
                           programs).

                  (d)      If during the remaining term hereof after the Change
                           of Control Date (i) Executive's employment is
                           terminated by the Company (or subsidiary), or (ii)
                           there shall have occurred a material reduction in
                           Executive's compensation or employment related
                           benefits, or a material change in Executive's status,
                           working conditions, management responsibilities or
                           titles, and Executive voluntarily terminates his
                           relationship with the Company within 60 days of any
                           such occurrence, or the last in a series of
                           occurrences, then Executive shall be entitled to
                           receive, subject to the provisions of subparagraphs
                           (e) and (f) below, a lump sum payment equal to 200%
                           of Executive's "base period income" as determined
                           under (e) below. Such amount will be paid to
                           Executive within 15 business days after his
                           termination of affiliation with the Company.

                  (e)      The Executive's "base period income" shall be his
                           base salary and annual incentive bonuses paid or
                           payable to him during or with respect to the twelve
                           month period preceding the date of his termination of
                           affiliation. If Executive has not been affiliated for
                           twelve months at the time of his termination of
                           affiliation, his "base period income" shall be his
                           annualized base salary at the rate then in effect and
                           any annual incentive bonus paid to Executive prior to
                           the

                           Executive with respect to his period of affiliation.

                  (f)      In the event of a proposed Change in Control, the
                           Company will allow Executive to participate in all
                           meetings and negotiations related thereto.

                  Paragraph 7 of this Agreement by the Executive or any of his
                  affiliates, associates, partners or agents, either directly or
                  indirectly, and that such right to injunction shall be
                  cumulative and in addition to whatever other remedies the
                  Company may possess.

         9.       CONSOLIDATION, MERGER OR SALE OF ASSETS. Nothing in this

                  of its assets to, another corporation which assumes this
                  Agreement, and all obligations of the Company hereunder, in
                  writing. Upon such consolidation, merger, or transfer of
                  assets and assumption, the term "the Company" as used herein,

                  success of the Company has been and will be substantial and
                  desires to assure the Company of the Executive's present and

         4.       TERMINATION.

                  4.1      TERMINATION FOR CAUSE. Notwithstanding anything
                           contained in this Agreement to the contrary, this

                           As used in the Agreement, "Cause" shall only mean (i)
                           subject to the following sentences, any action or
                           omission of the Executive which constitutes a willful
                           and material breach of this Agreement which is not
                           cured or as to which diligent attempts to cure have
                           not commenced within 30 business days after receipt
                           by Executive of notice of same, (ii) fraud,
                           embezzlement or misappropriation as against the
                           Company, or (iii) the conviction (from which no
                           appeal can be taken) of Executive for any criminal
                           act which is a felony. Upon any determination by the
                           Company's Board of Directors that Cause exists under
                           clause (i) of the preceding sentence, the Company
                           shall cause a special meeting of the Board to be
                           called and held at a time mutually convenient to the
                           Board and the Executive, but in no event later than
                           10 business days after Executive's receipt of the
                           notice contemplated by clause (i). Executive shall
                           have the right to appear before such special meeting
                           of the Board with legal counsel of his choosing to
                           refute any determination of Cause specified in such
                           notice, and termination of Executive's employment by
                           reason of such Cause specified in such notice, and
                           any termination of Executive's employment by reason
                           of such Cause determination shall not be effective
                           until Executive is afforded such opportunity to
                           appear. Any termination for Cause pursuant to clause
                           (ii) or (iii) of this Paragraph 4.1 shall be made in
                           writing to Executive, which notice shall set forth in
                           detail all acts or omissions upon which the Company
                           is relying for such termination. Upon any termination
                           pursuant to this Paragraph 4.1, the Company shall pay
                           to the Executive any unpaid Base Salary accrued
                           through the effective date of termination specified
                           in such notice. In addition, the Company shall pay
                           any benefits, if any, owed to Executive under any
                           plan provided for Executive under Paragraph 3 hereof
                           in accordance with the terms of such plan as in
                           effect on the date of termination of employment under
                           this paragraph 4.1. Except as provided above, the
                           Company shall have no further liability hereunder
                           (other than for reimbursement for reasonable business
                           expenses incurred prior to the date of termination,
                           subject, however, to the provisions of Paragraph 3.1
                           hereof).

                  4.2      DISABILITY. Notwithstanding anything to the contrary
                           contained in this Agreement if, during the Term
                           hereof the Executive suffers a disability (as defined
                           below) the Company shall, subject to the provisions
                           of Paragraph 4.3 hereof continue to pay Executive the
                           compensation provided in Paragraphs 2.1 and 2.2
                           hereof during the period of his disability, provided,
                           however, that, in the event Executive is disabled for
                           a period of more than 180 days in any 12 month period
                           (The "Disability Period"), the Company may, at its
                           election, by a vote of 75% of the members of the
                           Boards of Directors within 90 days from the end of
                           the Disability Period, terminate this Agreement. In
                           the event of such termination, (a) payment of the
                           Executive's Base Salary at the rate prevailing on the
                           date of termination of the Executive and fringe
                           benefits (to the extent permissible by applicable
                           law) shall be continued for a period of 12 months
                           after

                           such termination and (b) Executive shall receive a
                           bonus, equal to the amount of bonus paid to the
                           Executive during the 12 months preceding the date of
                           termination of the Executive. As used in this
                           Agreement, the term "disability" shall mean the
                           complete inability of Executive to perform his duties
                           under this Agreement as determined by an independent
                           physician selected with the approval of the Company
                           and the Executive. Except as provided above, the
                           Company shall have no further liability hereunder
                           (other than for reimbursement for reasonable business
                           expenses incurred prior to the date of termination
                           subject, however, to the provisions of Paragraph 3.1
                           hereof).

                  4.3      DEATH. In the event of the death of Executive during
                           the Term of this Agreement, the Company shall pay to
                           Executive's legal representative, any unpaid Base
                           Salary accrued through the date of his death plus a
                           bonus in an amount equal to the amount of bonus paid
                           in the 12 months preceding the date of death of the
                           Executive. Except as provided above, the Company
                           shall have no further liability hereunder (other than
                           for reimbursement for reasonable business expenses
                           incurred prior to the date of the Executive's death,
                           subject, however to the provisions of Paragraph 3.1
                           hereof).

         5.       MITIGATION.  In no event shall the Executive be obligated to 
                  seek other employment or take any other action by way of
                  mitigation of the amounts payable to the Executive under any
                  of the provisions of this Agreement.

         6.       CHANGE IN CONTROL.

                  (a)      For the purposes of this Agreement, a "Change of
                           Control" shall be deemed to have taken place if : (i)
                           any person, including a "group" as defined in Section
                           13(d)(3) of the Securities Exchange Act of 1934, as
                           amended, becomes the owner or beneficial owner of
                           Company securities, after the date of this Agreement,
                           having 20% or more of the combined voting power of
                           the then outstanding securities of the Company that
                           may be cast for the election of directors of the
                           Company (other than as a result of an issuance of
                           securities initiated by the Company, or open market
                           purchases approved by the Board, as long as the
                           majority of the Board approving the purchases is the
                           majority at the time the purchases are made), or (ii)
                           the persons who were directors of the Company before
                           such transactions shall cease to constitute a
                           majority of the Board of the Company, or any
                           successor to the Company, as the direct or indirect
                           result of or in connection with, any cash tender or
                           exchange offer, merger or other business combination,
                           sale of assets or contested election, or any
                           combination of the foregoing transaction. For Change
                           of Control purposes, if the company is a private
                           entity, then the trigger on change of control would
                           be the ownership, beneficially or otherwise, of 50%
                           of the voting securities.

                  (b)      The Company and Executive hereby agree that, if
                           Executive is affiliated with the Company on the date
                           on which a Change of control occurs, (the "Change of
                           Control Date"), the Company (or, if Executive is
                           affiliated with a subsidiary, the subsidiary) will
                           continue to retain Executive and Executive will
                           remain affiliated

                           with the Company (or subsidiary) for the period
                           commencing on the Change of Control Date and ending
                           on the second anniversary of such date, to exercise
                           such authority and perform such executive duties as
                           are commensurate with the authority being exercised
                           and duties being performed by the Executive
                           immediately prior to the Change of Control Date. If
                           after the Change of Control Executive is requested,
                           and, in his sole and absolute discretion, consents to
                           change his principal business location, the Company
                           will reimburse the Executive for his reasonable
                           relocation expenses, including, without limitation,
                           moving expenses, temporary living and travel expenses
                           for a reasonable time while arranging to move his
                           residence to the changed location, closing costs, if
                           any, associated with the sale of his existing
                           residence and the purchase of a replacement residence
                           at the changed location, plus an additional amount
                           representing a gross-up of any state or federal taxes
                           payable by Executive as a result of any such
                           reimbursement. If the Executive shall not consent to
                           change his business location, the Executive may
                           continue to provide the services required of him
                           hereunder from his then residence and/or business
                           address, and the Company shall continue to maintain
                           an office for Executive at that location commensurate
                           with the Company's office prior to the Change of
                           Control Date.

                  (c)      During the remaining term hereof after the Change of
                           Control Date, the Company (or subsidiary) will (i)
                           continue to pay Executive a salary at not less than
                           the level applicable to Executive on the Change of
                           Control Date, (ii) pay Executive bonuses in amounts
                           not less in amount than those paid during the twelve
                           month period preceding the Change of Control Date,
                           and (iii) continue employee benefit programs as to
                           Executive at levels in effect on the Change of
                           Control Date (but subject to such reductions as may
                           be required to maintain such plans in compliance with
                           applicable federal law regulating employee benefit
                           programs).

                  (d)      If during the remaining term hereof after the Change
                           of Control Date (i) Executive's employment is
                           terminated by the Company (or subsidiary), or (ii)
                           there shall have occurred a material reduction in
                           Executive's compensation or employment related
                           benefits, or a material change in Executive's status,
                           working conditions, management responsibilities or
                           titles, and Executive voluntarily terminates his
                           relationship with the Company within 60 days of any
                           such occurrence, or the last in a series of
                           occurrences, then Executive shall be entitled to
                           receive, subject to the provisions of subparagraphs
                           (e) and (f) below, a lump sum payment equal to 200%
                           of Executive's "base period income" as determined
                           under (e) below. Such amount will be paid to
                           Executive within 15 business days after his
                           termination of affiliation with the Company.

                  (e)      The Executive's "base period income" shall be his
                           base salary and annual incentive bonuses paid or
                           payable to him during or with respect to the twelve
                           month period preceding the date of his termination of
                           affiliation. If Executive has not been affiliated for
                           twelve months at the time of his termination of
                           affiliation, his "base period income" shall be his
                           annualized base salary at the rate then in effect and
                           any annual incentive bonus paid to Executive prior to
                           the

                           Executive with respect to his period of affiliation.

                  (f)      In the event of a proposed Change in Control, the
                           Company will allow Executive to participate in all
                           meetings and negotiations related thereto.

                  affiliates, associates, partners or agents, either directly or
                  indirectly, and that such right to injunction shall be
                  cumulative and in addition to whatever other remedies the
                  Company may possess.

                  of Paragraph 6 hereof.

                           Company, or (iii) the conviction (from which no
                           appeal can be taken) of Executive for any criminal
                           act which is a felony. Upon any determination by the
                           Company's Board of Directors that Cause exists under
                           clause (i) of the preceding sentence, the Company
                           shall cause a special meeting of the Board to be
                           called and held at a time mutually convenient to the
                           Board and the Executive, but in no event later than
                           10 business days after Executive's receipt of the
                           notice contemplated by clause (i). Executive shall
                           have the right to appear before such special meeting
                           of the Board with legal counsel of his choosing to
                           refute any determination of Cause specified in such
                           notice, and termination of Executive's employment by
                           reason of such Cause specified in such notice, and
                           any termination of Executive's employment by reason
                           of such Cause determination shall not be effective
                           until Executive is afforded such opportunity to
                           appear. Any termination for Cause pursuant to clause
                           (ii) or (iii) of this Paragraph 4.1 shall be made in
                           writing to Executive, which notice shall set forth in
                           detail all acts or omissions upon which the Company
                           is relying for such termination. Upon any termination
                           pursuant to this Paragraph 4.1, the Company shall pay
                           to the Executive any unpaid Base Salary accrued
                           through the effective date of termination specified
                           in such notice. In addition, the Company shall pay
                           any

                           benefits, if any, owed to Executive under any plan
                           provided for Executive under Paragraph 3 hereof in
                           accordance with the terms of such plan as in effect
                           on the date of termination of employment under this
                           paragraph 4.1. Except as provided above, the Company
                           shall have no further liability hereunder (other than
                           for reimbursement for reasonable business expenses
                           incurred prior to the date of termination, subject,
                           however, to the provisions of Paragraph 3.1 hereof).

                  4.2      DISABILITY. Notwithstanding anything to the contrary
                           contained in this Agreement if, during the Term
                           hereof the Executive suffers a disability (as defined
                           below) the Company shall, subject to the provisions
                           of Paragraph 4.3 hereof continue to pay Executive the
                           compensation provided in Paragraphs 2.1 and 2.2
                           hereof during the period of his disability, provided,
                           however, that, in the event Executive is disabled for
                           a period of more than 180 days in any 12 month period
                           (The "Disability Period"), the Company may, at its
                           election, by a vote of 75% of the members of the
                           Boards of Directors within 90 days from the end of
                           the Disability Period, terminate this Agreement. In
                           the event of such termination, (a) payment of the
                           Executive's Base Salary at the rate prevailing on the
                           date of termination of the Executive and fringe
                           benefits (to the extent permissible by applicable
                           law) shall be continued for a period of 12 months
                           after such termination and (b) Executive shall
                           receive a bonus, equal to the amount of bonus paid to
                           the Executive during the 12 months preceding the date
                           of termination of the Executive. As used in this
                           Agreement, the term "disability" shall mean the
                           complete inability of Executive to perform his duties
                           under this Agreement as determined by an independent
                           physician selected with the approval of the Company
                           and the Executive. Except as provided above, the
                           Company shall have no further liability hereunder
                           (other than for reimbursement for reasonable business
                           expenses incurred prior to the date of termination
                           subject, however, to the provisions of Paragraph 3.1
                           hereof).

                  4.3      DEATH. In the event of the death of Executive during
                           the Term of this Agreement, the Company shall pay to
                           Executive's legal representative, any unpaid Base
                           Salary accrued through the date of his death plus a
                           bonus in an amount equal to the amount of bonus paid
                           in the 12 months preceding the date of death of the
                           Executive. Except as provided above, the Company
                           shall have no further liability hereunder (other than
                           for reimbursement for reasonable business expenses
                           incurred prior to the date of the Executive's death,
                           subject, however to the provisions of Paragraph 3.1
                           hereof).

         5.       MITIGATION.  In no event shall the Executive be obligated to
                  seek other employment or take any other action by way of
                  mitigation of the amounts payable to the Executive under
                  any of the provisions of this Agreement.

         6.       CHANGE IN CONTROL.

                  (a)      For the purposes of this Agreement, a "Change of 
                           Control" shall be deemed to have taken place if : (i)
                           any person, including a "group" as defined in Section
                           13(d)(3) of the Securities Exchange Act of 1934, as
                           amended, becomes the

                           owner or beneficial owner of Company securities,
                           after the date of this Agreement, having 20% or more
                           of the combined voting power of the then outstanding
                           securities of the Company that may be cast for the
                           election of directors of the Company (other than as a
                           result of an issuance of securities initiated by the
                           Company, or open market purchases approved by the
                           Board, as long as the majority of the Board approving
                           the purchases is the majority at the time the
                           purchases are made), or (ii) the persons who were
                           directors of the Company before such transactions
                           shall cease to constitute a majority of the Board of
                           the Company, or any successor to the Company, as the
                           direct or indirect result of or in connection with,
                           any cash tender or exchange offer, merger or other
                           business combination, sale of assets or contested
                           election, or any combination of the foregoing
                           transaction. For Change of Control purposes, if the
                           company is a private entity, then the trigger on
                           change of control would be the ownership,
                           beneficially or otherwise, of 50% of the voting
                           securities.

                  (b)      The Company and Executive hereby agree that, if 
                           Executive is affiliated with the Company on the date
                           on which a Change of control occurs, (the "Change of
                           Control Date"), the Company (or, if Executive is
                           affiliated with a subsidiary, the subsidiary) will
                           continue to retain Executive and Executive will
                           remain affiliated with the Company (or subsidiary)
                           for the period commencing on the Change of Control
                           Date and ending on the second anniversary of such
                           date, to exercise such authority and perform such
                           executive duties as are commensurate with the
                           authority being exercised and duties being performed
                           by the Executive immediately prior to the Change of
                           Control Date. If after the Change of Control
                           Executive is requested, and, in his sole and absolute
                           discretion, consents to change his principal business
                           location, the Company will reimburse the Executive
                           for his reasonable relocation expenses, including,
                           without limitation, moving expenses, temporary living
                           and travel expenses for a reasonable time while
                           arranging to move his residence to the changed
                           location, closing costs, if any, associated with the
                           sale of his existing residence and the purchase of a
                           replacement residence at the changed location, plus
                           an additional amount representing a gross-up of any
                           state or federal taxes payable by Executive as a
                           result of any such reimbursement. If the Executive
                           shall not consent to change his business location,
                           the Executive may continue to provide the services
                           required of him hereunder from his then residence
                           and/or business address, and the Company shall
                           continue to maintain an office for Executive at that
                           location commensurate with the Company's office prior
                           to the Change of Control Date.

                  (c)      During the remaining term hereof after the Change of
                           Control Date, the Company (or subsidiary) will (i)
                           continue to pay Executive a salary at not less than
                           the level applicable to Executive on the Change of
                           Control Date, (ii) pay Executive bonuses in amounts
                           not less in amount than those paid during the twelve
                           month period preceding the Change of Control Date,
                           and (iii) continue employee benefit programs as to
                           Executive at levels in effect on the Change of
                           Control Date (but subject to such reductions as may
                           be required to maintain such plans in compliance with
                           applicable federal law regulating employee benefit
                           programs).

                  (d)      If during the remaining term hereof after the Change 
                           of Control Date (i) Executive's employment is
                           terminated by the Company (or subsidiary), or (ii)
                           there shall have occurred a material reduction in
                           Executive's compensation or employment related
                           benefits, or a material change in Executive's status,
                           working conditions, management responsibilities or
                           titles, and Executive voluntarily terminates his
                           relationship with the Company within 60 days of any
                           such occurrence, or the last in a series of
                           occurrences, then Executive shall be entitled to
                           receive, subject to the provisions of subparagraphs
                           (e) and (f) below, a lump sum payment equal to 200%
                           of Executive's "base period income" as determined
                           under (e) below and all Options granted to the
                           Executive pursuant to the Plan not fully vested shall
                           immediately vest upon such termination. Such amount
                           will be paid to Executive within 15 business days
                           after his termination of affiliation with the
                           Company.

                  (e)      The Executive's "base period income" shall be his
                           base salary and annual incentive bonuses paid or
                           payable to him during or with respect to the twelve
                           month period preceding the date of his termination of
                           affiliation. If Executive has not been affiliated for
                           twelve months at the time of his termination of
                           affiliation, his "base period income" shall be his
                           annualized base salary at the rate then in effect and
                           any annual incentive bonus paid to Executive prior to
                           the date of his termination of affiliation or payable
                           to Executive with respect to his period of
                           affiliation.

                  (f)      In the event of a proposed Change in Control, the
                           Company will allow Executive to participate in all
                           meetings and negotiations related thereto.

         7.       RESTRICTIVE COVENANT

                  7.1      NON-COMPETITION. During the Term and for a period of
                           two (2) years following the termination (other than

                           Executive's employment by the Company, Executive
                           shall not, directly or indirectly engage in or have
                           any interest in, directly or indirectly, any sole
                           proprietorship, partnership, corporation, business or
                           any other person or entity (whether as an employee,
                           officer, director, partner, agent, security holder,
                           creditor, consultant, or otherwise) that, directly or
                           indirectly, engages primarily in the development,
                           manufacturing, distribution or supply of products and
                           services competitive with the Company's and/or any
                           subsidiary's products and services in any and all
                           states in which the Company and/or any subsidiary

                           otherwise coming into the Executive's possession,

                  amount of which may be virtually impossible to ascertain. As a
                  result, the Executive recognizes and hereby acknowledges that
                  the Company shall be entitled to an injunction from any court

                  affiliates, associates, partners or agents, either directly or
                  indirectly, and that such right to injunction shall be
                  cumulative and in addition to whatever other remedies the
                  Company may possess.

         9.       CONSOLIDATION, MERGER OR SALE OF ASSETS.  Nothing in this
                  Agreement shall preclude the Company from consolidating or

                           between the Executive and the Company.

                  3.5      AUTOMOBILE ALLOWANCE. Throughout the Term of this
                           Agreement, the Company will pay Executive an
                           automobile allowance in the amount of $600.00 per
                           month. Such automobile allowance shall be for no more

         4.       TERMINATION.

                  4.1      TERMINATION FOR CAUSE. Notwithstanding anything
                           contained in this Agreement to the contrary, this
                           Agreement may be terminated by the Company for Cause.
                           As used in the Agreement, "Cause" shall only mean (i)
                           subject to the following sentences, any action or
                           omission of the Executive which constitutes a willful
                           and material breach of this Agreement which is not
                           cured or as to which diligent attempts to cure have
                           not commenced within 30 business days after receipt
                           by Executive of notice of same, (ii) fraud,
                           embezzlement or misappropriation as against the
                           Company, or (iii) the conviction (from which no
                           appeal can be taken) of Executive for any criminal
                           act which is a felony. Upon any determination by the
                           Company's Board of Directors that Cause exists under
                           clause (i) of the preceding sentence, the Company
                           shall cause a special meeting of the Board to be
                           called and held at a time mutually convenient to the
                           Board and the Executive, but in no event later than
                           10 business days after Executive's receipt of the
                           notice contemplated by clause (i). Executive shall
                           have the right to appear before such special meeting
                           of the Board with legal counsel of his choosing to
                           refute any determination of Cause specified in such
                           notice, and termination of Executive's employment by
                           reason of such Cause specified in such notice, and
                           any termination of Executive's employment by reason
                           of such Cause determination shall not be effective
                           until Executive is afforded such opportunity to
                           appear. Any termination for Cause pursuant to clause
                           (ii) or (iii) of this Paragraph 4.1 shall be made in
                           writing to Executive, which notice shall set forth in
                           detail all acts or omissions upon which the Company
                           is relying for such termination. Upon any termination
                           pursuant to this Paragraph 4.1, the Company shall pay
                           to the Executive any unpaid Base Salary accrued
                           through the effective date of termination specified
                           in such notice. In addition, the Company shall pay
                           any benefits, if any, owed to Executive under any
                           plan provided for Executive under Paragraph 3 hereof
                           in accordance with the terms of such plan as in
                           effect on the date of termination of employment under
                           this paragraph 4.1. Except as provided above, the
                           Company shall have no further liability hereunder
                           (other than for reimbursement for reasonable business
                           expenses incurred prior to the date of termination,
                           subject, however, to the provisions of Paragraph 3.1
                           hereof).

                  4.2      DISABILITY. Notwithstanding anything to the contrary
                           contained in this Agreement if, during the Term
                           hereof the Executive suffers a disability (as defined
                           below) the Company shall, subject to the provisions
                           of Paragraph 4.3

                           hereof continue to pay Executive the compensation
                           provided in Paragraphs 2.1 and 2.2 hereof during the
                           period of his disability, provided, however, that, in
                           the event Executive is disabled for a period of more
                           than 180 days in any 12 month period (The "Disability
                           Period"), the Company may, at its election, by a vote
                           of 75% of the members of the Boards of Directors
                           within 90 days from the end of the Disability Period,
                           terminate this Agreement. In the event of such
                           termination, (a) payment of the Executive's Base
                           Salary at the rate prevailing on the date of
                           termination of the Executive and fringe benefits (to
                           the extent permissible by applicable law) shall be
                           continued for a period of 12 months after such
                           termination and (b) Executive shall receive a bonus,
                           equal to the amount of bonus paid to the Executive
                           during the 12 months preceding the date of
                           termination of the Executive. As used in this
                           Agreement, the term "disability" shall mean the
                           complete inability of Executive to perform his duties
                           under this Agreement as determined by an independent
                           physician selected with the approval of the Company
                           and the Executive. Except as provided above, the
                           Company shall have no further liability hereunder
                           (other than for reimbursement for reasonable business
                           expenses incurred prior to the date of termination
                           subject, however, to the provisions of Paragraph 3.1
                           hereof).

                  4.3      DEATH. In the event of the death of Executive during
                           the Term of this Agreement, the Company shall pay to
                           Executive's legal representative, any unpaid Base
                           Salary accrued through the date of his death plus a
                           bonus in an amount equal to the amount of bonus paid
                           in the 12 months preceding the date of death of the
                           Executive. Except as provided above, the Company
                           shall have no further liability hereunder (other than
                           for reimbursement for reasonable business expenses
                           incurred prior to the date of the Executive's death,
                           subject, however to the provisions of Paragraph 3.1
                           hereof).

         5.       MITIGATION.  In no event shall the Executive be obligated to 
                  seek other employment or take any other action by way of
                  mitigation of the amounts payable to the Executive under
                  any of the provisions of this Agreement.

         6.       CHANGE IN CONTROL.

                  (a)      For the purposes of this Agreement, a "Change of 
                           Control" shall be deemed to have taken place if : (i)
                           any person, including a "group" as defined in Section
                           13(d)(3) of the Securities Exchange Act of 1934, as
                           amended, becomes the owner or beneficial owner of
                           Company securities, after the date of this Agreement,
                           having 20% or more of the combined voting power of
                           the then outstanding securities of the Company that
                           may be cast for the election of directors of the
                           Company (other than as a result of an issuance of
                           securities initiated by the Company, or open market
                           purchases approved by the Board, as long as the
                           majority of the Board approving the purchases is the
                           majority at the time the purchases are made), or (ii)
                           the persons who were directors of the Company before
                           such transactions shall cease to constitute a
                           majority of the Board of the Company, or any
                           successor to the Company, as the direct or indirect
                           result of or in connection with, any cash tender or
                           exchange offer,

                           merger or other business combination, sale of assets
                           or contested election, or any combination of the
                           foregoing transaction. For Change of Control
                           purposes, if the company is a private entity, then
                           the trigger on change of control would be the
                           ownership, beneficially or otherwise, of 50% of the
                           voting securities.

                  (b)      The Company and Executive hereby agree that, if
                           Executive is affiliated with the Company on the date
                           on which a Change of control occurs, (the "Change of
                           Control Date"), the Company (or, if Executive is
                           affiliated with a subsidiary, the subsidiary) will
                           continue to retain Executive and Executive will
                           remain affiliated with the Company (or subsidiary)
                           for the period commencing on the Change of Control
                           Date and ending on the second anniversary of such
                           date, to exercise such authority and perform such
                           executive duties as are commensurate with the
                           authority being exercised and duties being performed
                           by the Executive immediately prior to the Change of
                           Control Date. If after the Change of Control
                           Executive is requested, and, in his sole and absolute
                           discretion, consents to change his principal business
                           location, the Company will reimburse the Executive
                           for his reasonable relocation expenses, including,
                           without limitation, moving expenses, temporary living
                           and travel expenses for a reasonable time while
                           arranging to move his residence to the changed
                           location, closing costs, if any, associated with the
                           sale of his existing residence and the purchase of a
                           replacement residence at the changed location, plus
                           an additional amount representing a gross-up of any
                           state or federal taxes payable by Executive as a
                           result of any such reimbursement. If the Executive
                           shall not consent to change his business location,
                           the Executive may continue to provide the services
                           required of him hereunder from his then residence
                           and/or business address, and the Company shall
                           continue to maintain an office for Executive at that
                           location commensurate with the Company's office prior
                           to the Change of Control Date.

                  (c)      During the remaining term hereof after the Change of
                           Control Date, the Company (or subsidiary) will (i)
                           continue to pay Executive a salary at not less than
                           the level applicable to Executive on the Change of
                           Control Date, (ii) pay Executive bonuses in amounts
                           not less in amount than those paid during the twelve
                           month period preceding the Change of Control Date,
                           and (iii) continue employee benefit programs as to
                           Executive at levels in effect on the Change of
                           Control Date (but subject to such reductions as may
                           be required to maintain such plans in compliance with
                           applicable federal law regulating employee benefit
                           programs).

                  (d)      If during the remaining term hereof after the Change
                           of Control Date (i) Executive's employment is
                           terminated by the Company (or subsidiary), or (ii)
                           there shall have occurred a material reduction in
                           Executive's compensation or employment related
                           benefits, or a material change in Executive's status,
                           working conditions, management responsibilities or
                           titles, and Executive voluntarily terminates his
                           relationship with the Company within 60 days of any
                           such occurrence, or the last in a series of
                           occurrences, then Executive shall be entitled to
                           receive, subject to the provisions of subparagraphs
                           (e) and (f) below, a lump sum payment equal to 200%
                           of Executive's "base period income" as determined

                                       -5-

                           under (e) below. Such amount will be paid to
                           Executive within 15 business days after his
                           termination of affiliation with the Company.

                  (e)      The Executive's "base period income" shall be his
                           base salary and annual incentive bonuses paid or
                           payable to him during or with respect to the twelve
                           month period preceding the date of his termination of
                           affiliation. If Executive has not been affiliated for
                           twelve months at the time of his termination of
                           affiliation, his "base period income" shall be his
                           annualized base salary at the rate then in effect and
                           any annual incentive bonus paid to Executive prior to
                           the date of his termination of affiliation or payable
                           to Executive with respect to his period of
                           affiliation.

                  (f)      In the event of a proposed Change in Control, the
                           Company will allow Executive to participate in all

                  covenants contained in Paragraph 7 of this Agreement will

                  amount of which may be virtually impossible to ascertain. As a
                  result, the Executive recognizes and hereby acknowledges that
                  the Company shall be entitled to an injunction from any court
                  of competent jurisdiction enjoining and restraining any

                  affiliates, associates, partners or agents, either directly or
                  indirectly, and that such right to injunction shall be

                  Company may possess.

         9.       CONSOLIDATION, MERGER OR SALE OF ASSETS. Nothing in this

                  of its assets to, another corporation which assumes this
                  Agreement, and all obligations of the Company hereunder, in
                  writing. Upon such consolidation, merger, or transfer of
                  assets and assumption, the term "the Company" as used herein,
                  shall mean such other corporation and this Agreement shall
                  continue in full force and effect, subject to the provisions
                  of Paragraph 6 hereof.

         10.      BINDING EFFECT.  Except as herein otherwise provided, this
                  Agreement shall inure to the benefit of and shall be binding
                  upon the parties hereto, their personal representatives,

                           other than for Cause pursuant to Section 4.1, the
                           Company shall pay to the Executive upon such
                           termination an amount equal to (i) any unpaid Salary

                           incurred prior to the date of termination, subject,
                           however to the provisions of Section 3.1).

                           Notwithstanding anything contained in this Agreement
                           or the Plan to contrary, in the event of a

              parties hereto that a breach by the Executive of any of the

              Executive recognizes and hereby acknowledges that the Company
              shall be entitled to an injunction from any court of competent
              jurisdiction enjoining and restraining any violation of any or all

              assets to, another corporation which assumes this Agreement, and
              all obligations of the Company hereunder, in writing. Upon such
              consolidation, merger or transfer of assets and assumption, the
              term "the Company" as used herein, shall mean such other
              corporation and this Agreement shall continue in full force and

              judgement upon the award rendered by the Arbitrators may be
              entered in any Court having jurisdiction thereof. Venue of the
              arbitration shall be in Palm Beach County, Florida. Any
              controversy or claim shall be submitted to three arbitrators
              selected from the panels of the Arbitrators of the American
              Arbitrators Association. The arbitrators, in addition to any award
              made, shall have the discretion to award the prevailing party the
              costs of the proceedings, together with reasonable attorney's
              fees, provided that absent such award, each party shall bear the
              costs of its own counsel and presentation of evidence, and each
              party shall share equally the cost of such arbitration proceeding.
              Any award made hereunder may be docketed in a court of competent
              jurisdiction in Palm Beach County, Florida, and all parties hereby
              consent to the personal jurisdiction of such court for purposes of
              the enforcement of the arbitration award.

         11.  BINDING EFFECT. This Agreement shall be for the benefit of and
              binding upon the parties hereto and their perspective heirs,
              personal representatives, legal representatives, successors and,
              where applicable, assigns. The Executive may not assign his rights

              phrases, sentences, clauses or sections contained in this
              Agreement shall not affect the enforceability conditionally on
              their being valid in law, and, in the event that any one or more
              of the words, phrases, sentences, clauses, or sections contained
              in this Agreement shall be declared invalid, this Agreement shall

                    ("LANDLORD") AND NETSPEAK CORPORATION, A

    January 15, 1997. The Lease Term shall expire 36 months later, provided
    however, in the event that the Rent Commencement Date is a date other than

    Rent for the original space in Suites 104/106 shall remain the same as in
    the original Lease expect that it shall continue to escalate on the
    anniversary date of the original Lease as called for in Section 3.02 of the

                   FIRST AMENDMENT TO LEASE AGREEMENT BETWEEN
               REGENT HOLDING CORPORATION, A FLORIDA CORPORATION,
                    ("LANDLORD") AND NETSPEAK CORPORATION, A
                         FLORIDA CORPORATION, ("TENANT")
                             FOR PREMISES LOCATED AT

         902 CLINT MOORE ROAD, SUITES 104/106, BOCA RATON, FLORIDA 33487

                                   (CONTINUED)

6.  CAP ON CONTROLLABLE OPERATING COSTS: Notwithstanding anything to the
    contrary contained in the Lease, Landlord agrees to cap the increase in the
    "Controllable" components of Tenant's Proportionate Share of Operating Costs
    for the original Premises and the Expansion Premises during the Lease. Said
    increases will be limited to not more than seven (7%) percent per year
    during the specified Lease Term, on a cumulative basis from the "Base Year".
    For purposes of this paragraph, the Base Year shall be the budget year
    1996/1997. The following expense categories shall be defined as
    "non-controllable" and shall not be subject to any type of cap: trash
    removal, insurance, utilities, and taxes.

7.  SECURITY DEPOSIT: Tenant shall deposit with Landlord upon execution of
    this Lease Amendment, Thirty-Eight Thousand Nine Hundred Ninety-Eight and
    44/100 Dollars ($38,998.44) of additional security deposit (the "Additional
    Security Deposit"). Landlord will invest the Additional Security Deposit in
    a certificate of deposit or other low risk similar investment vehicle and
    the interest will accrue to the Tenant, to be paid to Tenant at the end of
    the Lease. Provided that Tenant does not default on any of the terms of the
    Lease during the Lease Term, Tenant will receive back one-third of the
    Additional Security Deposit at the end of the first lease year, and an
    additional third of the Additional Security Deposit at the end of the second
    lease year, with the final one-third of the Additional Security Deposit to
    be held through the end of the Lease by Landlord.

8.  ACCEPTANCE OF PREMISES: Tenant acknowledges that it has inspected the
    Expansion Premises, knows the condition thereof, and accepts such Expansion
    Premises, and specifically the buildings and improvements comprising the
    same, in their present condition, as suitable for the purposes for which the
    Expansion Premises are leased. Taking of possession by Tenant shall be
    deemed conclusively to establish that said buildings and other improvements
    are in good and satisfactory condition as of when possession was taken.
    Tenant further acknowledges that no representations as to the repair of the
    Expansion Premises, nor promises to alter, remodel or improve the Expansion
    Premises have been made by Landlord. Landlord makes no representations about
    the condition of the Building and/or the Expansion Premises. Landlord is not
    liable for any defects to the Building and/or the Expansion Premises,
    whether such defects are patent or latent, and makes no warranties as to the
    condition of the Expansion Premises. Notwithstanding anything else mentioned
    in this lease, if this lease is executed before the Expansion Premises
    become vacant or otherwise available and ready for occupancy, or if any
    present tenant or occupant of the Expansion Premises holds over, or fails to
    vacate the Expansion Premises when estimated by Landlord, and Landlord
    cannot, using good faith efforts, acquire possession of the Expansion
    Premises prior to the date above recited as the Commencement Date of this
    lease, Landlord shall not be deemed to be in default hereunder, nor in any
    way liable to Tenant because of such failure, and Tenant agrees to accept
    possession of the Expansion Premises at such time as Landlord is able to
    tender the same, which date shall thenceforth be deemed the "Commencement
    Date"; and the term of this lease shall automatically be extended so as to
    include the full number of months herein before provided for, except that if
    the commencement date is other than the first day of calendar month, such
    term shall also be extended for the remainder of the calendar month in which
    possession is tendered. Landlord hereby waives payment of rent covering any
    period prior to such tendering of possession. After the Commencement Date,
    Tenant shall, upon

truck loading areas specifically marked in red on said Exhibit B for the
exclusive use of Tenant. The Premises and the building within which the Premises
are located (the "Building") are part of a larger development (the
"Development") commonly known as CONGRESS CORPORATE PLAZA

      2.01 TERM OF LEASE. The term of this lease shall commence on the "Rent
Commencement Date", as hereinafter defined, and ending 36 months thereafter,
provided however, that in the event the rent commencement date is a date other
than the first day of a calendar month, said term shall extend for said number
of months in addition to the remainder of the calendar month following the rent
commencement date.

      2.02 RENT COMMENCEMENT DATE. The "Rent Commencement Date" shall be,
January 1, 1996 or date the Landlord delivers Premises to Tenant, which is late.
In the event this lease pertains to a building or building interior finish to be
constructed, the "Rent Commencement Date" shall be the date upon which the
buildings and other improvements erected and to be erected upon the premises
shall have been substantially completed in accordance with the plans and
specifications described on Exhibit "C" attached hereto and incorporated herein
by reference, provided however, that if Landlord shall be delayed in such
substantial completion as a result of: (i) Tenant's failure to agree to plans,
specifications, and cost estimates, within a reasonable period of time: (ii)
Tenant's request for materials, finishes or installations other than Landlord's
standard; (iii) Tenant's changes in plans: the commencement date and the payment
of rent hereunder shall be accelerated by the number of days of such delay, and
provided further that if Landlord cannot substantially complete the premises as
a result of any events (i) through (iii) above, Landlord may as its election
complete so much of Landlord's work as may be practical under the circumstances
and by written notice to Tenant, establish the commencement date as the date of
such partial completion, subject to any applicable accelerations due to delays
resulting from events (i) through (iii) above. Taking possession by Tenant shall
be deemed conclusively to establish that said buildings and other improvements
have been completed in accordance with the plans and specifications and that the
premises are in good and satisfactory condition, as of when possession was so
taken. Tenant acknowledges that no representations as to the repair of the
premises have been made by Landlord, unless such are expressly set forth in the
lease. After such "Rent Commencement Date" Tenant shall, upon demand, execute
and deliver to Landlord a letter of acceptance of delivery of the premises. In
the event of any dispute as to substantial completion of work performed, execute

      3.01 BASE RENT Tenant agrees to pay to Landlord rent for the premises, in
advance, without demand, deduction or set off, for the entire term hereof at the
rate of two thousand nine hundred eighty four and 00/100 ---- Dollars

the date hereof and a like monthly installment shall be due and payable on or
before the first day of each calendar month succeeding the rent commencement
date, except that the rental payment for any fractional calendar month at the
commencement of the lease period shall be prorated. The rental payment is
subject to adjustment as provided below.

      3.02 RENT ESCALATION The base rent shall be subject to adjustment on the
first day of January of each year of the Lease term (such date being hereafter
referred to as the "rent adjustment date") in the following manner: (a) Landlord
and Tenant agree that on and as of the adjustment date each year during the term
of this lease, Landlord may increase the base rental for the premises then due
under the lease to an amount equal to the product of the current annual rental,
including any prior adjustments, multiplied by a fraction the numerator being
the Consumer Price Index published for the October immediately preceeding the
rent adjustment date, and the denominator being the Consumer Price Index for the
October twelve (12) months prior to the rent adjustment date. For the first rent
adjustment date occuring during the term of this lease, any increase in annual
rental effective through this paragraph shall be reduced by the percentage of
the calendar year (the calendar year being the period from January 1st through
December 31) preceding the rent adjustment date that the Tenant was not in
possession of the premises (b) "Consumer Price Index" shall be the Consumer
Price Index for all Urban Consumer - U.S. City Average for all items ( 1982-84=

Labor Statistics is changed so that it affects the calculations achieved
hereunder, the Consumer Price Index shall be converted in accordance with a
conversion factor published by the United States Department of Labor, Bureau of
Labor Statistics. If the Consumer Price Index is discontinued or revised during
the term of the Lease, such other government index or computation with which it
is replaced shall be used in order to obtain substantially the same result as
would have been obtained if the Consumer Price Index had not been discontinued
or revised. Notwithstanding anything contained in this paragraph, the additional
rent payable by Tenant in any year pursuant to this paragraph shall in no event
be less than that paid in the prior year.

hereof the sum of eight thousand four hundred fifty three and 22/100-----------
- ------------------------------- Dollars ($8,453.22), which sum shall be held by
Landlord, without obligation for interest, as security for the full, timely and
faithful performance of Tenant's covenants and obligations under this Lease, it
being expressly agreed that such deposit is not an advance rental deposit or a
measure of Landlord's damages. Upon the occurrence of any event of default by
Tenant, Landlord may, from

time to time, without prejudice to any other remedy, use such funds to the
extent necessary to make good any arrears of rent or other payments due Landlord
hereunder, and any other damage, injury, expense or liability caused by Tenant's
default; and Tenant shall pay to Landlord on demand the amount so applied in
order to restore the security deposit to its original amount. Although the
security deposit shall be deemed the property of Landlord, any remaining balance

this Lease when Landlord shall have determined that all Tenant's obligations
under this Lease have been fulfilled.

      5.01 PERMITTED USE. The Premises shall be continously used for the sole
purpose of general business offices and/or for receiving, storing, shipping and

place in the premises including the truck apron and parking areas. Tenant shall
not permit any objectionable or unpleasant odors, smoke, dust, gas, noise or
vibrations to emanate from the Premises, nor take any other action which would
constitute a nuisance or would disturb or endanger any other tenants of
Development or unreasonably interfere with such tenants' use of their respective
premises or permit any use which would adversely affect the reputation of the
Development. Tenant shall not receive, store or otherwise handle any product,
material or merchandise which is explosive, highly flammable or constitutes a
hazardous substance or waste. Tenant shall not permit the Premises to be used
for any purpose (including, without limitation, the storage of merchandise) in

to the improper storage, handling, transportation or disposal of explosive,
highly flammable or hazardous materials or resulting from any other improper
use. Tenant shall comply with all governmental laws, ordinances and regulations
applicable to the Premises, and shall promptly comply with all governmental
orders and directives for the connection, prevention and abatement of any

ordinances and regulations, the Premises must be altered to accommodate lawfully
the use and occupancy thereof, such alterations shall be made only with the
consent of Landlord, but the entire cost thereof shall be borne by Tenant;
provided that the necessity of Landlord's consent shall in no way create any
liability against Landlord for failure of Tenant to comply with such laws,
ordinances and regulations. Tenant shall take whatever other actions are
necessary so that the Premises and Tenant's use thereof complies with the Fire
Prevention Code of the National Fire Protection Association and any other fire
prevention laws, ordinances, rules or regulations applicable to the Premises.

rent and on other charges payable hereunder shall be paid by Tenant to Landlord
with the payment of Tenant's rental payments and other charges payable 
hereunder.

      7.01 DEFINITION OF OPERATING COSTS. The term "Operating Costs shall mean
all costs and expenses paid or incurred by Landlord or on Landlord's behalf in
connection with the ownership, management, repair, replacement, remodeling,
maintenance and operation of the Development (including, without limitation, all
assessed real property taxes, assessments (whether general or special) and
governmental charges of any kind and nature whatsoever including assessments due
to deed restrictions and/or owner's associations, which accrue against the
building and/or development of which the premises are a part, the costs of
maintaining and repairing parking lots, parking structures, easements, and
landscaping, property management fees, utility costs to the extent not
separately metered, insurance premiums, depreciation of the costs of replacement
(as defined below) of the building and improvements in the Development but not
including any structural repairs or replacements which are normally
chargeable to capital accounts under sound accounting principles, and the
Building's share of costs of the Development). The term "operating costs" does
not include; (i) costs of alterations of tenants' premises; (ii) costs of curing
construction defects; (iii) interest and principal payments on mortgages, and
other debt cost; (iv) real estate brokers, leasing commissions or compensation;
(v) any cost or expenditure for which Landlord is reimbursed, whether by
insurance proceeds or otherwise; (vi) cost of any service furnished to any other
occupant of the Building which Landlord does not provide to tenant hereunder.
Structural repairs and replacements are repairs and replacements to the
foundations, load-bearing walls, columns and joists and replacement of roofing
and roof deck. Notwithstanding anything contained herein to the contrary,
depreciation of any capital improvements which are intended to reduce Operating
Costs, or are required under any governmental laws, regulations or ordinances
which were not applicable to the Building or the Development at the time it was
constructed, or are recommended by the N.F.P.A. Life Safety Code, shall be
included in Operating Costs. The useful life of any such improvement as well as
all non-structural replacements shall be reasonably determined by Landlord. In
addition, interest on the undepreciated cost of any such improvement or
non-structural replacement (at the prevailing construction loan rate available
to Landlord on the date the cost of such improvement was incurred) shall also be
included in Operating Costs. If Landlord selects the accrual method of
accounting rather than the cash accounting method for Operating Costs purposes,
Operating Costs shall be deemed to have been paid when such expenses have
accrued. Landlord shall have the right at any time and from time to time to
elect, which election shall be subject to revocation, to exclude that portion of
Operating Costs attributable to any separately assessed part of the Development
and any separate building within the Development. During any period that
Operating Costs attributable to any separately assessed part of the Development
and/or separate building are so excluded from Operating Costs, then for the
purposes of calculating Tenant's proportionate share of Operating Costs as
provided in Section 7.02, the denominator shall not include the rentable area of
such separately assessed part of the Development and/or such separate building.
Landlord may, in a reasonable manner, allocable insurance premiums for so-called
"blanket" insurance policies which insure other properties as well as the
Development and said allocated amount shall be deemed to be an Operating Cost.

      If at any time during the term of this lease, the present method of
taxation shall be changed so that in lieu of the whole or any part of any taxes,
assessments or governmental charges levied, assessed or imposed on real estate
and the improvements thereon, there shall be levied, assessed or imposed on
Landlord a capital levy or other tax directly on the rents received therefrom
and/or a franchise tax, assessment, levy or charge measured by or based, in
whole or in part, upon such rents for the present or any future building or
buildings on the premises, then all such taxes, assessments, levies or charges,
or the part thereof so measured or based, shall be deemed to be included within
the term "taxes" for the purposes hereof.

      7.02 TENANT'S PROPORTIONATE SHARE OF OPERATING COST. Tenant shall pay to
Landlord, as additional rent, its proportionate share of operating costs
calculated on the basis of the ratio set forth in Section 8.01. Any payments
with respect to any partial calendar year in which the Term commences or ends
shall be prorated. Tenant agrees to pay $1,003.37 per month as an escrow amount
for operating costs as defined in Article 7.01. Landlord may, at any time,
deliver to Tenant its estimate (or revised estimate) of such additional amounts
payable under this Section for each calendar year. On or before the first day of
the next month and on or before first day of each month thereafter, Tenant shall
pay to Landlord as additional rent such amount as Landlord reasonably determines
to be necessary to bring and keep Tenant current. As soon as practicable after
the close of each calendar

 Landlord:__________ Tenant: __________

year, Landlord shall deliver to Tenant a statement showing the total amount
payable by Tenant under this Article. If such statement shows an amount due from
Tenant that is less than the estimated payments previously paid by Tenant, it
shall be accompanied by a refund of the excess to Tenant or at Landlord's option
the excess shall be credited against the next monthly installment of rent. If
such statement shows an amount due from Tenant that is more than the estimated
payments paid by Tenant, Tenant shall pay the deficiency to Landlord, as
additional rent. In the event an amount is due and is not paid within thirty
(30) days after the date of Landlord's statement to tenant, the unpaid amount
shall bear interest at the rate of eighteen (18%) percent per annum from the
date of such statement until payment by tenant. Landlord and Tenant acknowledge
that certain of the costs of management, operation and maintenance, of the
Development are allocated among all of the buildings in the Development using
methods of allocation that are considered reasonable and appropriate under the
circumstances. Tenant hereby consents to such allocations provided that the
determination of such costs and the allocation of all or part thereof to
Operating Costs hereunder shall be in accordance with generally accepted
accounting principles applied on a consistent basis. Tenant or its'
representatives shall have the right after seven (7) days prior written notice
to Landlord to examine Landlord's books and records of Operating Costs during
normal business hours within twenty (20) days following the furnishing of the
statement to Tenant. Unless Tenant takes written exception to any item within
thirty (30) days following the furnishing of the statement to Tenant (which item
shall be paid in any event), such statement shall be considered as final and
accepted by Tenant. The taking of exception to any item shall not excuse Tenant
from the obligation to make timely payment based upon the statement as delivered
by Landlord.

      6.01 TENANT'S PROPORTIONATE SHARE. (a) Tenant's "proportionate share" as
used in this Lease with respect to the Building shall mean a fraction the
numerator of which shall be the rentable area contained in the Premises and the
denominator of which shall be the rentable area contained in the Building, as
determined by Landlord. Tenant's "proportionate share" as used in this Lease
with respect to costs relating to more than the Building, shall mean a fraction
the numerator of which shall be the rentable area contained in the Premises and
the denominator of which shall be the rentable area of all buildings, as
determined by Landlord, within the Development. Notwithstanding anything
contained in the Lease to the contrary, Landlord shall have the right, from time
to time, to add to or exclude from the Development real property and any
buildings constructed thereon. In the event Landlord elects to add to or exclude
from the Development, Landlord shall notify Tenant in writing of any such
addition or exclusion which notice shall describe the property added or
excluded.

customers, or any other person entering upon the Development as a result of
Tenant's business activities or caused by Tenant's default hereunder.

(b) Tenant at its own cost and expense, enter into a regularly scheduled
preventive maintenance/service contract with a maintenance contractor

corporate resolution, proof of due authorization by partners, or other
appropriate documentation evidencing the due authorization of such party to
enter into this Lease. Nothing herein contained shall give any other tenant in
the Development or the Building any enforceable rights either against Landlord
or Tenant as a result of the covenants and obligations of either party set forth
herein. If there is more than one Tenant, the obligations of Tenant shall be
joint and several. Any indemnification of, insurance of, or option granted to
Landlord shall also include or be exercisable by Landlord's agents and
employees.

      (c) The captions inserted in this Lease are for convenience only and in no
way define, limit or otherwise describe the scope or intent of this Lease, or
any provision hereof, or in any way affect the interpretation of this Lease.

      (d) In no event shall Landlord's liability for any breach of this Lease
exceed the amount of rental then remaining unpaid for the then current Term
(exclusive of any renewal periods which have not then actually commenced). This
provision is not intended to be a measure or agreed amount of Landlord's
liability with respect to any particular breach and shall not be utilized by any
court or otherwise for the purpose of determining any liability of Landlord
hereunder, except only as a maximum amount not to be exceeded in any event. In
addition, it is expressly understood and agreed that nothing in this Lease shall
be construed as creating any liability against Landlord, or its successors and
assigns, personally, and in particular without limiting the generality of the
foregoing, there shall be no personal liability to pay any indebtedness accruing
hereunder or to perform any covenant, either express or implied, herein
contained, and that all personal liability of Landlord, or its successors and
assigns, of every sort, if any, is hereby expressly waived by Tenant, and that
so far as Landlord, or its successors and assigns is concerned Tenant shall look
solely to the Building for the payment thereof.

      (e) Except as set forth in Section 8.01 above, this Lease may not be
altered, changed or amended except by an instrument in writing signed by both
parties hereto.

      (f) All obligations of Tenant not fully performed as of the expiration or
earlier termination of the term of this Lease shall survive the expiration or
earlier termination of the Term, including without limitation, all payment
obligations with respect to Operating Costs and all obligations concerning the
condition of the Premises. Upon the expiration or earlier termination of the
Term, and prior to Tenant vacating the Premises, Landlord and Tenant shall
jointly inspect the Premises and Tenant shall pay to Landlord any amount
estimated by Landlord as necessary to put the Premises, including without
limitation heating and air conditioning systems and equipment therein, in good
condition and repair. Any work required to be done by Tenant prior to its
vacation of the Premises which has not been completed upon such vacation, shall
be completed by Landlord and billed to Tenant at cost plus fifteen percent.
Tenant shall also, prior to vacating the Premises, pay to Landlord the amount,
as estimated by Landlord, of Tenant's obligation hereunder for Operating Costs.
All such amounts shall be used and held by Landlord for payment of such

obligations of Tenant hereunder, with Tenant being liable for any additional
costs therefor upon demand by Landlord, or with any excess to be returned to
Tenant after all such obligations have been determined and satisfied, as the
case may be. Any security deposit held by Landlord shall be audited against the
amount payable by Tenant under this Section.

     (g) If any clause, provision or portion of this Lease or the application
thereof to any person or circumstance shall be invalid or unenforceable under
applicable law, such event shall not affect, impair or render invalid or
unenforceable the remainder of this Lease nor any other clause, phrase,
provision or portion hereof, nor shall if affect the application of any clause,
phrase, provision or portion hereof to other persons or circumstances, and it is
also the intention of the parties to this Lease that in lieu of each such
clause, phrase, provision or portion of this Lease that is invalid or
unenforceable, there be added as a part of this Lease a clause, phrase,
provision or portion as similar in terms to such invalid or unenforceable
clause, phrase, provision or ponion as may be possible and be valid and
enforceable.

     (h) Submission of this Lease shall not be deemed to be a reservation of the
Premises. Landlord shall not be bound hereby until its delivery to Tenant of an
executed copy hereof signed by Landlord, already having been signed by Tenant,
and until such delivery Landlord reserves the right to exhibit and lease the
Premises to other prospective tenants. Notwithstanding anything contained herein
to the contrary Landlord may withhold delivery of possession of the Premises
from Tenant until such time as Tenant has paid to Landlord the security deposit
required hereunder and the first month's rent as required hereunder, and any
other sums required hereunder.

     (i) Tenant shall at any time and from time to time within ten (10) days
after written request from Landlord, execute and deliver to Landlord an estoppel
certificate, in form reasonable satisfactory to Landlord.

     (j) Whenever a time period is prescribed for action to be taken by
Landlord, Landlord shall not be liable or responsible for, and there shall be
excluded from the computations for any such time period, any delays due to
causes beyond the control of Landlord.

     (k) Radon is a naturally occurring radioactive gas that, when it has
accumulated in a building in sufficient quantities, may present health risks to
persons who are exposed to it over a time. Levels of radon that exceed federal
and state guidelines have been found in buildings in Florida.  Additional
information regarding radon and radon testing may be obtained from your county
public health unit. The above statement is incorporated in the lease as a
requirement in order to comply with Florida Statute 404,056(8).

                     NETSPEAK CORP., A FLORIDA CORPORATION.
                       ("TENANT") FOR PREMISES LOCATED AT

         902 CLINT MOORE ROAD, SUITES 1O4/106, BOCA RATON, FLORIDA 33487



29.01    AMERICANS WITH DISABILITIES ACT: Tenant, at Tenant's sole expense,
         shall comply with all laws, rules, orders, ordinances, directions,
         regulations and requirements of federal, state, county and municipal
         authorities as applicable now in force or which may hereafter be in
         force, which shall impose any duty upon the Landlord or Tenant with
         respect to the use, occupation or alteration of the premises.

30.01    ACCEPTANCE OF PREMISES: Tenant acknowledges that it has inspected the
         Premises, knows the condition thereof, and accepts such Premises, and
         specifically the buildings and improvements comprising the same, in
         their present condition, as suitable for the purposes for which the
         Premises are leased. Taking of possession by Tenant shall be deemed
         conclusively to establish that said buildings and other improvements
         are in good and satisfactory condition as of when possession was taken.
         Tenant further acknowledges that no representations as to the repair of
         the Premises, nor promises to alter, remodel or improve the Premises
         have been made by Landlord, unless such are expressly set forth in this
         lease. If this lease is executed before the Premises become vacant or
         otherwise available and ready for occupancy, or if any present tenant
         or occupant of the Premises holds over, and Landlord cannot, using good
         faith efforts, acquire possession of the Premises prior to the date
         above recited as the commencement date of this lease, Landlord shall
         not be deemed to be in default hereunder, nor in any way liable to
         Tenant because of such failure, and Tenant agrees to accept possession
         of the Premises at such time as Landlord is able to tender the same,
         which date shall thenceforth be deemed the "commencement date"; and the
         term of this lease shall automatically be extended so as to include the
         full number of months hereinbefore provided for, except that if the
         commencement date is other than the first day of calendar month, such
         term shall also be extended for the remainder of the calendar month in
         which possession is tendered. Landlord hereby waives payment of rent
         covering any period prior to such tendering of possession. After the
         commencement date, Tenant shall, upon demand, execute and deliver to
         Landlord a letter of acceptance of delivery of the Premises.

31.01    ENVIRONMENTAL MATTERS: Tenant hereby agrees to conform and comply with
         all provisions of Exhibit E, known herein as Environmental Matters.

              RIDER TO THE LEASE AGREEMENT BETWEEN REGENT HOLDING
              CORPORATION, A FLORIDA CORPORATION, ("LANDLORD") AND
                     NETSPEAK CORP., A FLORIDA CORPORATION.
                       ("TENANT") FOR PREMISES LOCATED AT

         902 CLINT MOORE ROAD, SUITES 104/106, BOCA RATON, FLORIDA 33487

                                   (CONTINUED)

32.01    LANDLORD'S LIEN PROTECTION: Neither Tenant nor anyone claiming by,
         through or under Tenant, including, without limitation, contractors,
         subcontractors, material men, mechanics and laborers, shall have any
         right to file or place mechanic's, material men's or other liens of any
         kind whatsoever upon the demised premises or upon the tract of land
         described on Exhibit A, or any portion thereof; on the contrary, any
         such liens are specifically prohibited and shall be null and void and
         of no further force or effect.

         Tenant has no power to subject Landlord's interest in the demised
         premises to any claim or lien of any kind or character and any persons
         dealing with Tenant must look solely to the credit of the Tenant for
         payment.

33.01    INSURANCE REQUIREMENT: Certified copies of insurance policies, as
         described in paragraph 16.01, together with receipt evidencing payment
         of premiums therefore, shall be delivered to Landlord prior to Tenant
         taking possession of the Premises. Tenant's failure to provide proof of
         insurance shall not delay the Rent Commencement date as defined in
         paragraph 2.02 above. In the event Landlord notifies Tenant in writing
         that the Premises are ready for occupancy, but Tenant has not furnished
         Landlord with proof of insurance, all rent and other charges due under
         the lease shall begin to accrue as if Tenant had taken possession of
         the Premises as of the date of Landlord's notice.

34.01    ASSIGNING, MORTGAGE & SUBLETTING: Any transfer, sale, pledge, or other
         disposition, in any single transaction or cumulatively during the term
         of the Lease or any renewal or extension thereof, of a legal or an
         equitable interest in as much as fifty percent (50%) of the shares or
         assets of Tenant shall be deemed an assignment of the Lease, and
         prohibited without the express written consent of Landlord, as provided
         in paragraph 14.01 of the Lease.

35.01    RIGHT OF FIRST REFUSAL: If Landlord receives an offer (an "Outside
         Offer") from a prospective tenant to lease space contiguous to the
         Premises which Landlord desires to accept, Tenant shall have the right
         of first refusal, subordinate to any preexisting rights or options to
         renew, to lease such space from the Landlord upon the identical terms
         and provisions contained in the Outside Offer. Tenant shall have seven
         (7) calendar days from receipt of notification by Landlord of the
         Outside Offer to elect to exercise this right of first refusal by
         providing written notification of such election to the Landlord and
         entering into a legally binding agreement. In the event the Tenant
         fails to timely exercise this right of first refusal, then the Landlord
         shall be free to consummate the lease transaction specified in the
         Outside Offer with the prospective tenant which has submitted the
         Outside Offer or with any other prospective tenant. Tenant's right of
         first refusal shall terminate upon Tenant electing not to exercise its
         right, and thereafter Landlord may lease the space without first
         offering it to Tenant.

36.01    LETTER OF CREDIT: In addition to the Security Deposit paid by Tenant
         under the Lease (Paragraph 4.01), Tenant agrees to supply Landlord with
         an irrevocable Letter of Credit in the amount of $16,906.45 and drawn
         on a Florida Bank, said Bank to be reasonably approved in advance by
         Landlord. The Letter of Credit shall be in full force and effect
         throughout thc Lease Term.
