ITEM 1. BUSINESS

      We are engaged in the design and development of products and services in
the fields of electronic commerce, Internet access and advanced telephony
applications. All of our design and development activities are conducted within
the State of Israel.

      Our activities are currently centered in two distinct areas: (i) the
completion of the design and development of a unique technology that facilitates
the provision of rapid power line telecommunication services to ordinary
business and personal consumers and (ii) the establishment, initially in Israel,
of a nationwide screen phone network that is designed to enable e-commerce and
Internet browsing for consumers who do not have access to, or are unable or
unwilling to use, personal computers.

      Since our founding in June 1996, we have been engaged primarily in the
design and development of smart card based technologies and products. Owing to a
fundamental reassessment of general market developments in the field of smart
card based technologies, we elected to leverage our experience and expertise
acquired in the area of smart card based technologies to the design, development
and commercialization of our proprietary technologies in the field of
power-line- telecommunications (PLT) and screen phones. We have ceased all
research and design efforts in the smart card area.

      We have recently established a wholly-owned subsidiary, PLT Solutions,
Inc. to promote a unique technology designed to facilitate the use of existing
electricity power lines and grids in the United States and Japan for Internet,
telephone and data transfer to ordinary business and personal users. Existing
electrical power grids are not currently in use for high speed data transmission
due to certain power utility infrastructure limitations. We have designed and
developed proprietary technology that overcome these infrastructure limitations.
We believe that our technology will be especially attractive to Internet
providers/integrators (AOL, Cisco, IBM etc.).

      We also have a 40% interest in a newly established Israeli company,
Kliks.com Ltd., which is engaged in designing and attempting to establish a
nationwide Screen Phone network in Israel. The network will enable Internet
access for a wide segment of the population which is less familiar with the use
of personal computers (PC's), or belongs to the large segment of populace which
does not have a PC. Our Vice-President, Mr. Bernie Wolff, holds the remaining
60% interest in Kliks.

      A discussion of each of power line transmission, the screen-phone network
follows:

                       ELECTRICAL POWER-LINE TRANSMISSION

General Background Relating To Internet Access

      Worldwide Internet communications can be divided into the "backbone"
network and the "access" network. The backbone network is carried over optical
fibers between cities and continents, and we believe, provides essentially
unlimited capacity for sending relatively large amounts of data over long
distances. However, the optical fiber technology used for the backbone network
is too expensive to extend to each

<PAGE>

individual user. Accordingly, distributing the data from the backbone network to
homes and business is done via an "access" network, also referred to as the
"last mile" network.

     To date, traditional Access networks have included modems connected to
conventional telephone lines, higher speed digital subscriber telephone lines
(ADSL), cable TV with data modems in set-top boxes and, more recently, wireless
networks. However, we believe that the traditional access methods have certain
drawbacks. The ADSL method typically requires high implementation costs. Cable
TV modems are characterized by loss of rapidity of service when the number of
subscribers reaches a critical mass and wireless networks are unreliable, as is
generally the case in the use of cell phones.

     One of the more rapid and affordable methods of access utilizes
conventional electrical power grids, also known as power-line communication, to
transmit data to individual users. The use of electrical power grids as an
access method is, in our view, an especially attractive proposition given the
widespread infrastructure "wiring" already in place. The same electrical wiring
that carries electrical power to individual homes and business can also transmit
high speed data. However, there are certain infra-structural limitations that
have, until recently, effectively precluded the use of conventional electrical
power grids as an affordable access method.

     Electrical power is generated at a power station and furnished to an urban
or rural substation which services a neighborhood, typically extending over
several square miles. The electrical power generated at the power station is
sent over relatively high voltage lines and needs to be reduced to a lower
voltage for further distribution within the neighborhood. At the neighborhood
substation level, a "stepdown transformer" reduces the high voltage electrical
power generated to "medium" voltage for further distribution within the
neighborhood. The medium voltage needs to be further reduced to familiar 120
volts by "distribution transformers" located near the neighborhood homes and
businesses.

     However, the distribution transformers were designed for 60 Hz power, and
completely fail to transmit the high frequency, data-carrying signals arriving
over the grid from the substation. Therefore, to ensure that data can get from
the neighborhood lines to the 120 volt outlets, a "bypass coupler" is needed as
a bridge around the distribution transformer. These couplers need to be
physically (and therefore electrically) connected directly to the high voltage
lines. To achieve the electrical connection the coupler needs to withstand high
voltage, and is therefore very expensive to manufacture.

      Our proprietary technology enables coupling the data to and from the
neighborhood distribution lines without the need to establish an electrical
connection. Our propietary coupler, a prototype of which is ready for
feasibility demonstation, either uses the existing insulation of underground
cables or is easily insulated to slip around overhead medium voltage
distribution wires. Accordingly, the manufacturing costs are significantly
reduced in comparison to the conventional bypass coupler.

Advantages of Utilizing Existing Power lines for High Speed Data Transmission

      The use of electricity power lines to connect homes and businesses to the
Internet, for telephony or for any other form of data transmission provides both
consumers and suppliers with a range of compelling economic and practical
benefits.

      The advantages in employing power line communication include:

   o Coverage - the power grid is the most extensive "wire" network in the
   world. More individuals and businesses have access to the electrical grid
   than any other "wire" network, including telephone lines. The low voltage
   wiring extends to every room in the business and home, and obviates expensive
   and disruptive wiring.

   o Modernity - the electric grid in most areas of the world is more modern and
   better maintained than any other wired communication network.

   o Simplicity - power line communications are not burdened by telephony's
   conventional technologies, including outdated routers, bridges, gateways,
   legacy switches and software, which slow down traditional communications.

      Fueled by recognition of the overwhelming financial and practical
benefits, interest in high speed power-line telecommunication has expanded.
Technical conferences on the subject are frequent, and attended by power
companies, as well those from other relevant fields including telecommunications
and networking companies such as 3COM, Nortel, Cisco, Cinergy and others. PLT
chips and modems for in-house networking are maturing, and a large number of
companies are vying for this market. Network speeds of data transmission are
rapidly increasing. To realize maximum benefit from the in-home network, users
are looking to connect it to a high speed Internet feed. So an initial group of
users who already use PLT and trust the technology is emerging, with a built-in
demand for access connectivity to the Internet backbone.

      Europe's 230 volt line voltage allows a large number of customers to be
fed by each distribution transformer. Most of the trials of neighborhood PLT
have taken place in Europe, but have usually limited themselves to sending data
over the 230 volt feed lines, and have not attempted to establish
substation-to-home neighborhood Access networks.

Comparison of Power-Line Communication with other High Speed Access Solutions

   o Digital Subscriber Line (DSL) - subscribers need to be within approximately
   5.5 km of the telephone company's central office. It is a point-to-point
   connection, so the one time installation cost to the end user is high. Users
   report that installation times are long, and availability is sparse. Phone
   companies need to invest considerably to beef up their networks, which were
   never designed for high speed data and very long session times.

      In contrast, our networks can be deployed in entire neighborhoods in a
   matter of days, and their direct connection to the backbone means no
   bottlenecks or heavy investments. Also, telephone outlets typically exist in
   only one to three locations within a premise, while power outlets are already
   installed in every room.

<PAGE>

   o T1 Trunks - T1 (1.544 Mbps) is a digital telephony trunk, typically used by
   phone companies to provide telephone service to large organizations. It
   provides high speed in both directions, the equivalent of 24 telephone
   conversations. But, its $250 monthly tariff prices it out of the market for
   most home and small business users.

   Satellite - Some satellites serve as data relay stations, and some of these
   are connected to the Internet backbone to provide high speed data to users.
   The user needs to buy, mount and aim a fairly large dish, he needs a
   microwave transmitter/receiver, and a special modem. Since the ground-based
   antennae cannot beam a strong signal back to the satellite, only low speeds
   of 56 kilobits per second can be sent from the user to the Web, the same data
   speed as is available over dialup modems.

   o Cable Modems - TV cable networks have been designed and constructed as
   one-way feed systems, providing a large number of channels to a large user
   base. Subscribers to cable companies share their cable lines with other
   subscribers, sometimes a very large number of them, so even the high promised
   data speeds (up to 36Mbps) may not guarantee good service during peak usage.
   Sending data back from the user to the network is problematic over cable TV
   lines, due to the accumulation of noise generated by the television sets and
   other devices, from all of the connected customers, reaching the TV cable.
   Cable companies must invest substantially in upgrading their equipment to be
   able to send data upstream, and in laying cables outside of urban areas. Data
   service is available to only a small percentage of Internet users.

      In contrast, PLT exploits the natural segmentation of the neighborhood
   power grid, to keep the number of users sharing the data stream within
   reasonable limits. Typically, only 50 - 200 premises share a common phase
   line in the US, and the number of users demanding simultaneous downloads of
   large files is likely to be very small. PLT Solutions expects the typical
   user to enjoy data rates from 1 - 10 megabits per second, usually enough to
   pass the maximum data rate available from the Web site being accessed, for
   the foreseeable future.

      In addition, cable TV outlets typically exist in only one or two locations
   within a premise, while power outlets are already installed in every room.
   This saves expensive and disruptive rewiring, when data users include PCs,
   Internet telephones, and eventually many intelligent appliances.

   o Wireless Local Loop - Similar to cellular telephone network deployment,
   microwave relay stations may be deployed in neighborhoods to provide last
   mile Access for Internet data to homes and businesses. The same problems of
   communications reliability that beset cellular telephones are likely to
   affect wireless local loop systems. These include need for near line of sight
   between hub and user, multiple reflections of signals in dense residential
   areas, the blocking effects of the metal building materials, and seasonal
   variation of foliage and effects of precipitation on radio transmission
   quality.

<PAGE>

      Another inherent limitation is the frequency bandwidth available in the
   shared domain of radio frequencies, and the difficulty of providing
   significant future upgrades in data speeds without regulatory permission and
   massive retrofitting of equipment.

Our Solution

      PLT Solutions proposes utilization of conventional electrical power lines
as its access channel. The data path is as follows: (i) high speed data arrives
over the optical fiber backbone cable, routed to the neighborhood utility
substation, (ii) the specific data intended for the subscribers of a particular
neighborhood is selected from the general data stream by a standard network
device called a router, (iii) the digital data is turned into a high frequency
signal using a modem, and (iv) the high frequency, data-carrying signal is
carried onto the neighborhood power distribution line using our proprietary
coupler.

      At each distribution transformer, serving typically two to six premises,
the data is received, as follows: (i) the high frequency, data-carrying signal
is coupled from the neighborhood power distribution line onto the customers' 120
volt feed lines using our proprietary coupler, (ii) the high frequency signal is
converted back to data using a modem, and (iii) the PC or other user device
listens to the neighborhood data, and accepts that data which is addressed to
itself.

      The process of sending data from the user device to its destination uses
the above pathway in the reverse direction.

Integrating Our Coupler into a Complete Access Network

      In order to provide a comprehensive power line access solution to the end
user, our coupler is required to be integrated with the following technologies:

o     a spread spectrum modem
o     a media access control processor
o     a network control system
o     user interface devices

      The spread spectrum modem is the device which turns the digital data into
a high frequency signal, and its spread spectrum character both minimizes radio
interference and provides tolerance for the noise interference to be found on
power lines. The media access control processor is the "traffic cop" which
coordinates packaging of data into "packets," and who sends listens. The network
control system provides overall control of traffic. And the user interface
devices translate the high frequency signals coming over the power line into
useable data for their computers and other devices.

<PAGE>

      In order to provide a comprehensive solution in an expeditious manner, we
need to coordinate our efforts with companies experienced in the modem and
networking fields. We are currently examining options respecting alliances with
such companies. We cannot provide any assurance that we will be successful in
concluding such alliances.

      Our solution seeks to provide an initial system data rate of 10 megabits
per second, and we believe that this can be upgraded to several times this
speed, with future developments in hardware and software. For example, current
modems use relatively simple "modulation" techniques that turn data bits into
high frequency energy. Future modems are expected to use more sophisticated
modulation techniques which allow the same frequency band to carry at least
three times more data.

Our Coupler Product

      We believe that we have completed the design and development of a unique
coupling method with very low projected manufacturing costs and that does not
materially impact on power grid reliability. Our prototype product has passed
high voltage testing at a lab in the US and has been field tested for
communications between two transformers at a power company site.

     Our coupler features:

o    Low cost (25% cost of an existing solution)

o    Capacity for very high data rates, exceeding 10 megabits per second, which
     is 200 times faster than dialup modems can provide.

o    Installation without interruption of service to customers

o    No material impact on reliability of electrical grid

o    Works even during power outage

o    Installation without exposure to high voltages

o    Virtually unlimited life of service

     We are currently in the process of arranging for the pilot testing of our
proposed product with potential commercial partners. Further productization
steps will include Standards testing and certification, mechanical package
design and tooling for mass production.

     To provide a end to end data distribution network, we need to collaborate
with a modem and media access control processor chip manufacturer, and a data
network equipment manufacturer.

<PAGE>

      It will be necessary for us to obtain the cooperation of a utility company
in order to progress with full pilot testing and commercialization.

Production & Supplies

      Our proprietary couplers utilize special magnetic materials and high
voltage weatherproof plastics, as well as standard components that are
obtainable from local sources. We have identified potential suppliers who can
supply the special magnetic materials and high voltage weatherproof plastics. We
have held meetings with these suppliers, and initial estimates have been made
for one time tooling costs. We do not regard any one supplier as essential to
our operations since equivalent replacements for the components are either
available from one or more sources at competitive prices. We believe that
approximate cost to the Company of the components for the couplers should not
exceed $20 per unit. The Company currently does not have a written contract with
any supplier for any of the components.

      Subject to successful completion of pilot testing, we intend to initially
assemble the couplers at our facilities. We anticipate that we will need to
retain appropriate professionals to assemble and test the couplers. We estimate
that with 5 assemblers and 3 testers we can fill orders of up to eight thousand
units per month. As quantities grow, offshore assembly facilities may be
selected, to increase production capabilities and reduce cost.

      We anticipate that all of future suppliers and the assemblers will be
certified to recognized international quality assurance standards.

Competition

      The Internet Access market is highly competitive. We face competition from
many Internet access and service providers with significantly greater financial
resources, well-established brand names and large, existing customer bases.
Moreover, we expect the level of competition to intensify in the future. We
expect significant competition from:

      I.    (ISPs) Internet Service Providers

      ISPs provide Internet access to residential and business customers. These
companies provide Internet access over existing networks. They have nationwide
marketing presences and strategic or commercial alliances with telecom carriers.
Significant ISPs include Concentric Network Corporation, Mindspring Enterprises,
Inc., PSINet Inc. and Verio, Inc. Incumbent Local Exchange Carriers, ILECs, such
as SBC Communications, Inc.,GTE Corp., Ameritech Corp. and US WEST, Inc.

      II.   Wireless and Satellite Service Providers.

      We also face competition from other fixed-wireless services, such as
Teligent, Inc., NEXTLINK Communications, Inc. Winstar Communications, Inc. AT&T
has also announced plans to expand its fixed-wireless network to compete for
voice and high-speed data customers in businesses and residences. We also may
face competition from satellite-based systems. Motorola Satellite Systems, Inc.,
Hughes Communications, Inc. (a subsidiary of General Motors Corporation),
Teledesic LLC and others have filed applications with the FCC for global
satellite networks that can be used to provide ubiquitous two-way broadband
voice and data services to fixed locations. Many of these competitors are
offering, or may soon offer, technologies and services that will directly
compete with some or all of our service offerings.

      III.  Other Telephony Services

      We also face intense competition from other providers of telephony
transmission services. Many of the existing providers of telephony services,
such as regional Bell operating companies and other local exchange carriers,
have significantly greater financial and other resources than us and better
established brand awareness in their service areas.

      IV.   Subscription Television Competition Hardwire Cable.

      Our principal subscription television competitors are traditional hardwire
cable operators such as AT&T Broadband & Internet Services (formerly
TeleCommunications, Inc.), and Time Warner Entertainment. Hardwire cable
companies generally are well established and known to our potential customers
and have significantly greater financial and other resources than we have. In
addition, these competitors are also bundling additional services with their
cable TV services, such as high-speed Internet access, to enhance their
products. Direct Broadcast

<PAGE>

Satellite ("DBS"). DBS service is available from DirecTV,Inc., which is a
subsidiary of the Hughes Electronic unit of General Motors Corporation and
Echostar Communications Corporation. We compete with many retail distributors of
DirecTV and other DBS service.

                                 SCREEN PHONES

      Through Kliks.com Ltd., an Israeli company, we intend to serve as the
vehicle in Israel to offer the screen phone as an effective tool for offering a
full range of Internet and e-commerce services to the business (B-to-B) and
public consumers. Kliks has developed a concept that offers all the elements
essential for capitalizing on current consumer interest in the Internet and e-
commerce, while overcoming most of the shortcomings of a PC-based market
approach by the on-line services industry.

      The means to deliver services to the end-user will be through
screen-enhanced telephones phones supporting enhanced telephony services that
are now commercially available. The screen phones are Internet enabled with an
integrated alphanumeric keyboard, and a reader capable of handling smart cards
for electronic payments. The model relies on using Internet enhanced screen
phones instead of the personal computer (PC) as the conduit for electronic
commerce.

      Kliks is proposing a staged approach for this opportunity by which
consumers will initially be offered standard applications (e-mail, advanced
telephony, and Internet browsing/access) through the screen phone with the
opportunity at a second stage to expand the services to include a full suite of
e-commerce activities. The user being able to order consumer items/services at
home via the screen phone in the comfort of the home creates a very attractive
and friendly environment for enhancing e-commerce activities.

      Kliks success will be dependant on its ability to obtain the exclusive
distribution rights in Israel for a screen phone. Kliks is currently negotiating
such rights for a screen phone which it believes to be a superior product. In
addition, Kliks will need to enter into strategic relationships with
well-established providers, such as the national telecommunication carrier
(Bezeq), and a platform operator, who together will launch a portfolio of screen
telephony and electronic services to both business and the consumer.

Customer Profile

      The screen phone which Kliks intends to offer in the Israeli market, is a
conventional telephone. For the implementation plan, the screen phone deployment
will start in upscale communities with a high percentage of families with
children, business seniors and professional people. Once the business is
established, deployment can proceed to the wider community, with a goal of
achieving high penetration in the minimum period of time.

      In addition to revenues from home-based services, we believe that Kliks
will be

<PAGE>

able to generate revenues from large organizations whose business depends on
establishing and maintaining long-term account relationships with customers.
This will include banks and other financial service companies, telephone and
utility companies, consumer orientated services (supermarkets, travel agencies,
etc.) and leisure organizations (cable, pay per view, lottery etc.). Within a
community, sponsors will use this channel to deliver local content services,
thereby developing sustainable long-term relationships. Community services
organizations (schools, local authorities, libraries etc.) will have a direct
electronic link into the homes in their community, in order to promote local
services. This will be achieved through conventional e-mail messaging through
the server.

Competition

      Kliks will face competition primarily from two different avenues.

      Alternative Screen phones - there are other Internet Screen phones
available on the market, but so far none are being marketed in Israel. Kliks
believes that the screen phone for which it is currently negotiating the
exclusive Israeli distributions rights is a superior product in the market and
that it will provide a high entry barrier for potential competitors.

      Other Communication Media - there are several media which do, or are
expected, to provide services which overlap with the Kliks portal:

      ISPs (Internet Service Providers) - offer online portals. However, the
screen phone is well positioned against the PC, since it is a more user-friendly
device, always switched on and is more cost-effective. Moreover the US and UK
experience has shown widespread acceptance of screen phones in communities with
higher than average PC penetration.

      Web TV is expected to enter the market with similar services using the TV
as interface. The TV is currently seen primarily as an entertainment device,
while the screen phone will be easier and quicker to access.

      Cellular - operators in Israel are establishing portals that will enable
their subscribers to access the web and information services. Wireless Access
Protocol (WAP) services are under development which will be delivered to mobile
phones. Although these services will also be suited to screen phones, they are
primarily for

<PAGE>

mobile use. They do not, in our view, represent a threat to the screen phone in
the home due to differences in communication costs and size of the screen among
other factors.

      Online Banking Services - Existing commerce systems (telephone/home
banking services) are being offered by financial institutions. Most Israeli
banks offer this service to their customers, and the current number of
subscribers per bank is approaching 150,000. Apart from cash withdrawals and
cash deposits, all teller services can be activated. Similar services exist for
commercial banking, with additional services in wholesale banking such as L/C,
Foreign Exchange, etc. Citigroup has announced that within the next few months,
it will enter the local market, and concentrate on offering electronic banking
services to high net-worth customers.

ordinary and routine claims incidental to our business. We cannot estimate with
certainty its ultimate legal and financial liability with respect to such
pending litigation matters. However, the Company believes, based on its
examination of such matters, that the Company's ultimate liability will not have
a material adverse effect on its financial position, results of operations or
cash flows.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

      We held our Annual Meeting of Shareholders on December 29, 1999 and the
shareholders voted as to the following: (a) election of Michael Braunold and
Aryeh Weinberg as directors to serve for a term of one (i) year or until their
respective successors are elected and (b) the approval of Brightman Almagor &
Co. (a member of Deloitte Touche Tohmatsu), as independent public accountants of
the Company for the year ending December 31, 1999. All of these matters were
approved.

Voting Results were as follows:

                   FOR            AGAINST           ABSTAIN
1.   Directors     1,691,152      20,500            0

2.   Auditors      1,689,152      22,500            0

      As of April 10, 2000, there were approximately 68 holders of record of our
Common Stock. We believe that there are a significant number of shares of our
common stock held either in nominee name or street name brokerage accounts and
consequently, we are unable to determine the number of beneficial owners of our
common stock.

      We have not declared or paid dividends on the Common Stock since our
formation, and we does not anticipate paying dividends in the foreseeable
future. Declaration or payment of dividends, if any, in the future, will be at
the discretion of the Board of Directors and will depend on our then current
financial condition, results of operations, capital requirements and other
factors deemed relevant by the Board of Directors.

ITEM 6. PLAN OF OPERATIONS

      The following discussion and expositions should be read in conjunction
with the Financial Statements and related Notes contained elsewhere in this Form
10-KSB.

      We are engaged in the design and development of products and services in
the fields of electronic commerce, Internet access and advanced telephony
applications. All of our design and development activities are conducted within
the State of Israel.

      Our activities are currently centered in two distinct areas: (i) the
completion of the design and development of a unique technology designed to
facilitate the provision of rapid power line telecommunication services to
ordinary business and personal consumers and (ii) the establishment, initially
in Israel, of a nationwide screen phone network that is designed to enable
e-commerce and Internet browsing for consumers who do not have access to, or are
unable or unwilling to use, personal computers.

      Since our founding in June 1996, we have been engaged primarily in the
design and development of smart card based technologies and products. Owing to a
fundamental reassessment of general market developments in the field of smart
card based technologies, we elected to leverage our experience and expertise
acquired in the area of smart card based technologies to the design, development
and commercialization of our proprietary technologies in the field of
power-line- telecommunications (PLT) and screen phones. We have effectively
ceased all research and design efforts in the smart card area.

<PAGE>

      We have recently established a wholly-owned subsidiary, PLT Solutions,
Inc. to promote a unique technology designed to facilitate the use of existing
electricity power lines and grids in the United States and Japan for Internet,
telephone and data transfer to ordinary business and personal users. Existing
electrical power grids are not currently in use for high speed data transmission
due to certain power utility infrastructure limitations. We have designed and
developed proprietary technology that overcome these infrastructure limitations.
We believe that our technology will be especially attractive to Internet
providers/integrators (AOL, Cisco, IBM etc.).

      We also have a 40% interest in a newly established Israeli company,
Kliks.com Ltd. ("Kliks"), which is engaged in designing and attempting to
establish a nationwide Screen Phone network in Israel. The remaining 60%
interest in Kliks is held by our Vice-President, Mr. Bernie Wolff. The network
will enable Internet access for a wide segment of the population which is less
familiar with the use of personal computers (PC's), or belongs to the large
segment of populace which does not have a PC.We are engaged in the design and
development of products and services in the fields of electronic commerce,
internet and telephony activities. All of our design and development activities
are conducted within the State of Israel.

      As a development stage company, We have a limited operating history upon
which an evaluation of our prospects can be made. Our prospects must therefore
be evaluated in light of the problems, expenses, delays and complications
associated with a new business.

      To date, we have incurred net losses aggregating $6,078,528, reflecting
principally research and development expenses and general and administrative
expenses. We expect to incur significant up-front expenditures in connection
with the new focus of our operations, and operating losses are expected to
continue for the foreseeable future. There can be no assurance that we can be
operated profitably in the future. Our continuation as a going-concern is
dependent upon, among other things, our ability to obtain additional financing
when and as needed, and to generate sufficient cash flow to meet its obligations
on a timely basis. We may also explore other business options including
strategic joint ventures and business combinations, including investments in
other companies, or mergers.

      As of December 31, 1999, we have expended $1,721,837 on our research and
development activities (including $558,195 received from the Office of Chief
Scientist of the Israeli Ministry of Industry and Trade).

      In February 2000, we issued $1,000,000 of our 10% Convertible Debentures
to private investors. The Debentures were issued pursuant to the terms of an
agreement which further provides that, subject to certain conditions, the
investors will purchase an additional $1,000,000 of Debentures no later than
five days after the effective date of a registration statement covering the
Common Stock into which the Debentures may be converted. In January 2000, the
investors pre-funded $250,000 of this obligation. The Debentures mature on
February 28, 2002. The Debentures are convertible into shares of the Company's
Common Stock at a conversion rate $0.40 per share, subject to adjustment under
certain conditions.

<PAGE>

      In connection with the issuance of the 10% Convertible Debentures, we
issued to Debenture holders warrants to purchase, in the aggregate, 625,000 of
our Common Shares at an exercise price per share of $1. The warrants expire in
April 2003.

      In connection with the sale of our Debentures, we issued to an independent
consultant warrants, exercisable through February 2002, to purchase up to 1.3
million shares of our common stock, at an exercise price per share of $1.00. As
a result of the issuance of these warrants, we recognized a significant non-cash
financing costs, and recorded approximately $2.4 million as deferred financing
costs and charged the entire balance to operations.

      In February 2000 we converted outstanding debts of approximately $700,000
in principal and accrued interest into common stock of the Company.

      We anticipate that cash on hand, as well as the $1.0 million (before
deducting approximately $137,500 in fees and commissions) due to be invested
upon purchase of the additional Convertible Debentures, will allow us to
maintain operations through December 31, 2000. Thereafter, we will need
additional financing to maintain operations. We are currently reviewing possible
private sales of equity or debt with equity features. We have no commitments for
any such financing and there can be no assurance that we will obtain additional
capital when needed or that any such additional capital will not have a dilutive
effect on current stockholders.

      1998 Stock Incentive Option Plan. The Company's current policy is that all
full time key employees be considered annually for the possible grant of stock
options, depending upon employee performance. The criteria for the awards are
experience, uniqueness of contribution and level of performance shown during the
year. Stock options are intended to improve loyalty to the company and help make
each employee aware of the importance of our business success.

      The Company has adopted the 1998 Incentive and Non-Qualified Stock Option
Plan (the "1998 Option Plan"). The 1998 Option Plan provides for the grant to
qualified employees (including officers and directors) of options to purchase
shares of common stock.

<PAGE>

      The 1998 Option Plan is administered by the Board of Directors. The Board
has discretion to select the optionee and to establish the terms and conditions
of each option, subject to the provisions of the 1998 Option Plan. Options
granted under the 1998 Option Plan may be non-qualified stock options or
Incentive Stock Options (an option which qualifies under Section 422 of the
Internal Revenue Code) but in any case the exercise price of options granted may
not be less than 100% of the fair market value of the common stock as of the
date of grant (110% of the fair market value if the grant is an Incentive Stock
Option to an employee who owns more than 10% of the outstanding common stock),
unless the Board decides otherwise. Options may not be exercised more than 10
years after the grant (five years if the grant is an Incentive Stock Option to
any employee who owns more than 10% of the outstanding common stock). The Board
may, in its discretion (i) accelerate the date or dates on which all or any
particular option or options granted under the 1998 Stock Plan may be exercised,
or (ii) extend the dates during which all, or any particular, option or options
granted under the 1998 Stock Plan may be exercised, provided, that no such
extension will be permitted if it would cause the 1998 Option Plan to fail to
comply with Section 422 of the Code or with Rule 16b-3 of the Securities and
Exchange Act of 1934, as amended. Except as otherwise determined by the Board at
the date of the grant of the option, and subject to the provisions of the 1998
Option Plan, an optionee may exercise an option at any time within one year (or
within such lesser period as may be specified in the applicable option
agreement) following termination of the optionee's employment or other
relationship with the Company if such termination was due to the death or
Disability (as defined) of the optionee but in no event later than the
expiration date of the Option. Except as otherwise determined by the Board at
the date of the grant of an Option, if the termination of the optionee's
employment or other relationship is for any other reason the Option will expire
immediately upon such termination. Options granted under the 1998 Option Plan
are not transferable and may be exercised only by the respective grantees during
their lifetimes or by their heirs, executors or administrators in the event of
death. Under the 1998 Option Plan, shares subject to canceled or terminated
options are reserved for subsequently granted options. The number of options
outstanding and the exercise price thereof are subject to adjustment in the case
of certain transactions such as mergers, recapitalizations, stock splits or
stock dividends.

      As of March 30, 2000, 230,000 options to purchase shares of common stock
were outstanding under the 1998 Option Plan.

                          INDEPENDENT AUDITORS' REPORT

To the Shareholders of
Ambient Corporation

We have audited the accompanying consolidated balance sheets of Ambient
Corporation (a development stage company) and subsidiary (collectively, "the
Company") as of December 31, 1999 and 1998, and the related consolidated
statements of operations, changes in shareholders' deficiency and cash flows for
the years then ended. 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 auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of Ambient
Corporation and subsidiary as of December 31, 1999 and 1998, and the results of
their operations, changes in shareholders' deficiency and cash flows for the
years then ended in conformity with accounting principles generally accepted in
the United States.

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 1 to the
consolidated financial statements, the Company incurred a net loss in 1999 of
approximately $1.1 million (and approximately $6.1 million since inception) and
anticipates that it will continue to incur losses for some time. In addition,
the Company had a working capital deficit of approximately $0.7 million and a
shareholders' deficiency of approximately $1million as of December 31, 1999.
Although the Company raised net proceeds of approximately $3.4 million from an
initial public offering in February 1998, it has substantially utilized all of
such proceeds, primarily for product development. The Company's continued
existence as going concern is dependent on obtaining additional financing for
product development and commercialization. After the balance sheet date, the
Company raised debt financing, through convertible debenture in the amount of $1
million. The Company continues to seek out other potential sources of equity
capital, but there can be no assurance that it will be able to do so in the
foreseeable future. These matters raise substantial doubt about the Company's
ability to continue as a going concern. Management plans in regard to these
matters are also described in Note 1. The financial statements do not include
any adjustments that might result from the outcome of this uncertainty.

                          (A Development Stage Company)
                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
                                (in U.S. dollars)

NOTE 1 - DESCRIPTION OF BUSINESS AND GENERAL

      A.    Description of business

            Ambient Corporation ("Ambient"), a development stage company, was
            founded in June 1996 to design and develop advanced smart card
            interface technology. A smart card is a credit card-sized plastic
            card equipped with an integrated circuit that can store and transfer
            information in electronic form.

            In August 1996, Ambient purchased substantially all of the assets
            and assumed substantially all of the liabilities of Gen
            Technologies, Inc., a smart card research and development company,
            at their approximate book value, including the capital stock of its
            subsidiary, Gen Tec Ltd. (which subsequently changed its name to
            Ambient Ltd.). The results of operations of Gen Technologies, Inc.
            prior to the acquisition were not material. Ambient and its
            subsidiary are collectively referred to herein as "the Company."

            The Company has recently commenced the design and development of
            products and services in the field of electronics commerce, internet
            and telephony activities.

            The Company's activities are currently centered in two distinct
            areas; the completion of the design and development of a unique
            technology designed to facilitate the provision of rapid power line
            telecommunication (PLT) services to ordinary business and personal
            consumers and the establishment, initially in Israel, of nationwide
            screen phone network that design to enable internet access for
            consumers who do not have access to, or unable, or unwilling to use,
            personal computers.

            The Company has not generated any revenues since inception.

      B.    Going concern assumption

            The Company incurred a net loss in 1999 of approximately $1.1million
            (and approximately $6.1 million since inception) and anticipates
            that it will continue to incur losses for some time. In addition,
            the Company had a working capital deficit of approximately
            $0.7million and a shareholders' deficiency of approximately
            $1.1million as of December 31, 1999. Although the Company raised net
            proceeds of approximately $3.4 million from an initial public
            offering in February 1998, it has substantially utilized all of such
            proceeds, primarily for product development. The Company's continued
            existence is dependent on obtaining additional financing for product
            development and commercialization.

            In February 2000, the Company issued $1,000,000, 10% convertible
            debentures to private investors. The debentures mature on February
            28, 2002 (see Note 15).

            Management's plans to continue operations in the normal course of
            business include the following: (i) continuing to seek out potential
            sources of equity capital; (ii) seeking out strategic partnerships;
            (iii) negotiating with a number of companies to install pilot
            projects; and (iv) diversification through establishment of new
            subsidiaries in the fields of internet technology and
            communications. In management's estimation, the above measures, if
            substantially realized, should enable the Company to continue
            operating through at least December 31, 2000, although there can be
            no assurance of this.

                          (A Development Stage Company)
                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
                                (in U.S. dollars)

NOTE 1 - DESCRIPTION OF BUSINESS AND GENERAL (cont.)

      B.    Going concern assumption (cont.)

            In order to reduce its fixed costs until the above measures are
            partially or fully realized, during 1999, the Company terminated the
            employment of most of its employees. The Company has also undertaken
            other cost-cutting measures, such as reducing its lease space. In
            addition, due to the Company's adverse liquidity position, the
            Company did not pay salaries and salaries related amount to its
            remaining employees and to related institutions for several months.

            The above matters raise substantial doubt about the Company's
            ability to continue as a going concern. The financial statements do
            not include any adjustments that might be necessary should the
            Company be unable to continue as a going concern.

      C.    Use of estimates in preparation of financial statements

            The preparation of financial statements in conformity with generally
            accepted accounting principles requires management to make estimates
            and assumptions that affect the reported amounts of assets and
            liabilities and disclosure of contingent assets and liabilities as
            of the date of the financial statements, and the reported amounts of
            revenues and expenses during the reporting periods. Actual results
            could differ from those estimates.

      D.    Nature of industry

            The industries in which Company conducts business is characterized
            by rapid changes. Internet and internet related products quickly
            become out of date because of technological and other advances.
            Accordingly, the industry is typified by the constant need to
            develop and introduce new and enhanced products, which may result in
            substantial costs without any guarantee that such new products or
            enhancements will produce significant revenues.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      The consolidated financial statements have been prepared in conformity
      with accounting principles generally accepted in the United States. The
      significant accounting policies followed in the preparation of the
      financial statements, on a basis consistent with prior years, are as
      follows:

      A.    Cash and cash equivalents

            Cash and cash equivalents consist of cash and demand deposits in
            banks and other financial institutions, and other short-term, highly
            liquid investments (primarily interest-bearing time deposits) with
            maturity dates not exceeding three months from the date of deposit.

      B.    Functional currency and foreign currency translation

            The currency of the primary economic environment in which the
            operations of the Company are conducted is the U.S. dollar
            ("dollar"). Therefore, the Company uses the dollar as its functional
            and reporting currency. Certain of the dollar amounts in the
            financial statements may represent the dollar equivalent of other
            currencies, and may not necessarily be exchangeable for dollars.

                          (A Development Stage Company)
                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
                                (in U.S. dollars)

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (cont.)

            Transactions and balances denominated in dollars are presented at
            their dollar amounts. Non-dollar transactions and balances are
            remeasured into dollars in accordance with the principles set forth
            in Statement No. 52, "Foreign Currency Translation," of the
            Financial Accounting Standards Board of the United States ("FASB").
            Transaction gains and losses are reflected in net financing
            expenses.

      C.    Consolidation

            The consolidated financial statements include those of Ambient and
            its 95%-owned subsidiary. Material intercompany transactions and
            balances have been eliminated in consolidation. The Company has
            recorded 100% of the subsidiary's losses since acquisition and,
            accordingly, no minority interest has been recorded in the financial
            statements.

      D.    Property and equipment

            Property and equipment are presented at cost, less accumulated
            depreciation. Depreciation is calculated based on the straight-line
            method over the estimated useful lives of the assets, as follows:

                                                                    Years
                                                                    -----
            Computers                                             4 (primarily)
            Motor vehicles                                        7
            Machinery and equipment                               7
            Furniture and office equipment                       14 (primarily)

            Management reviews property and equipment and other long-lived
            assets on a periodic basis to determine whether events or changes in
            circumstances indicate that the carrying amount of such assets may
            not be recoverable.

      E.    Research and development

            Research and development costs, net of participation by the
            Government of Israel through the Ministry of Industry and Trade's
            Office of the Chief Scientist ( "Office of the Chief Scientist"),
            are charged to operations as incurred.

      F.    Stock-based compensation

            The Company accounts for employee stock-based compensation in
            accordance with Accounting Principles Board Opinion No. 25,
            "Accounting for Stock Issued to Employees." Pursuant to this
            accounting standard, the Company records compensation for stock and
            stock options granted to employees at the date of grant based on the
            difference, if any, between the cost to the employee of the stock or
            options (including exercise price) and the market value of the
            Company's stock at that date. Deferred compensation is amortized to
            compensation expense over the vesting period of the stock or
            options. Grants to non-employees are accounted for at fair value as
            of the date of grant in accordance with Statement No. 123,
            "Accounting for Stock-Based Compensation," ("SFAS 123") of the FASB.
            The pro forma effects of the application of SFAS 123 with respect to
            grants to employees are presented in Note 16.

                          (A Development Stage Company)
                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
                                (in U.S. dollars)

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (cont.)

      G.    Loss per share

            Loss per share is presented in accordance with Statement No. 128
            ("SFAS 128") of the FASB, "Earnings per Share." Pursuant to this
            standard, basic earnings (loss) per share exclude the dilutive
            effects of convertible securities and are computed by dividing
            income (loss) available to common shareholders by the
            weighted-average number of common shares outstanding for the period.
            Diluted earnings (loss) per share reflect the potential dilutive
            effect of all convertible securities and are presented in the
            financial statements with the same prominence as basic earnings per
            share. Diluted loss per share information has not been separately
            presented herein since the Company has recorded a net loss for all
            years presented and, accordingly, the effect of potentially dilutive
            securities is antidilutive. Retroactive recognition has been given
            in the calculation of basic loss per share to shares issued for
            nominal consideration prior to the Company's initial public
            offering.

      H.    Fair value of financial instruments

            The Company's financial instruments are principally non-derivative
            assets and non-derivative liabilities, such as cash and cash
            equivalents, deposits in banks, receivables, loan receivable,
            short-term and long-term credit, accounts payable and other current
            liabilities. Because of the nature of these financial instruments,
            fair value generally equals or approximates the amounts presented in
            these financial statements.

NOTE 3 - RESTRICTED CASH

            In connection with a line of credit and short-term loan from a bank
            (see Note 6), the Company is required to maintain a compensating
            balance which is restricted for a period of up to one year. The
            restricted balance amounted to $ 84,820 as of December 31, 1999
            (December 31, 1998 - $131,259).

NOTE 4 - LONG TERM INVESTMENT

            On May 20, 1998, a letter of intent was signed between the Company
            and Ordacard Hi-Tech Industries (1995) Ltd. ("Ordacard"), an Israeli
            manufacturer of plastic ID and bank cards, relating to a proposed
            merger with Ordacard, which was to be consummated by December 31,
            1998.

            Pursuant to the letter of intent, the Company was to provide
            $1,000,000 of loans to Ordacard - $350,000 upon execution of the
            letter of intent and $650,000 by July 1, 1998. The loans were to be
            evidenced by two convertible promissory notes, secured by Ordacard's
            assets and subordinated to Ordacard's secured bank loans in
            existence as of the date of payment. The notes were to bear interest
            at an annual rate of 6%. In addition, the Company was to carry out a
            private or public offering of equity securities with minimum net
            proceeds (after commissions and expenses) of $7.5 million by
            December 31, 1998. Since the merger and the equity financing were
            not consummated by December 31, 1998, the Company had the option to
            demand full payment of the aggregate outstanding principal and
            accrued interest on the notes through the date of payment, or
            convert, at its sole option, the aggregate outstanding principal and
            interest into 50,000 shares of Ordacard.

NOTE 4 - LONG TERM INVESTMENT (cont.)

            The Company provided the $350,000 loan upon execution of the letter
            of intent and provided additional cash advances during the third
            quarter of 1998 in the total amount of $485,000, such that the
            amounts provided to Ordacard by the Company aggregated $835,000.
            During 1999 the Company has elected to convert the loan into 36,490
            shares of Ordacard common stock, and has written down the investment
            to its estimated fair value of $170,000 (1998, Loan Term Receivable
            - $350,000).

                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
                                (in U.S. dollars)

NOTE 7 - NOTES PAYABLE

            In June 1998, the Company conducted a private placement of units.
            Each unit consisted of: (i) a promissory note in the principal
            amount of $50,000 and (ii) warrants to purchase 10,000 shares of the
            Company's common stock. The Company sold 12 units in the private
            placement for aggregate consideration of $600,000. The aggregate
            fair value of the consideration allocated to the warrants was
            $21,600, which was credited to additional paid-in capital.

            The notes bear interest at an annual rate of 10% and are repayable
            at the earlier of: (i) 12 months from the date of issuance or (ii)
            consummation by the Company of any public or private equity or debt
            financing in excess of $1,500,000 (as well as certain other
            conditions).

            The purchase price for each share pursuant to the warrants is equal
            to the lower of: (i) $8.00 and (ii) the offering price of the
            Company's common stock in a subsequent public offering with
            aggregate proceeds to the Company of at least $1,500,000. The
            warrants are exercisable for a period of four years from the date of
            issuance.

            In February 2000 the Company entered into an agreement to convert
            these notes to equity. Principal and interest of approximately
            $700,000 were converted into 3,490,000 shares of the Company's
            common stock.

NOTE 9 - LIABILITY FOR SEVERANCE PAY

            Israeli law and labor agreements determine the obligations of the
            Company to make severance payments to dismissed employees and to
            employees leaving employment under certain other circumstances. The
            obligation for severance pay benefits, as determined by Israeli Law,
            is based upon length of service and the employee's most recent
            salary. This obligation is partially funded by the purchase from
            outside insurance companies of managers' insurance policies, which
            are controlled by the insurance companies and are not under the
            control and management of the Company.

            Expenses relating to severance pay benefits were $22,560 and $23,564
            in 1999 and 1998, respectively.

NOTE 10 - CONTINGENT LIABILITIES AND COMMITMENTS

      A.    In connection with its research and development, the Company
            received participation payments from the Office of the Chief
            Scientist of $231,767, $230,452 and $95,976 for the years 1999, 1998
            and 1996, respectively. In return for such participation, the
            Company is committed to pay royalties at a rate of 3%-5% of sales of
            the product, up to 100% of the amount of grants received (1998 -
            $220,364 included in receivables and prepaid expenses).

      B.    The Company is committed to pay royalties to a shareholder of its
            subsidiary, in connection with technology transferred by him to the
            Company, at rates of between 15% and 20% of the net proceeds from
            all sales, less the cost of components, as defined in an agreement
            with the shareholder.

      C.    The Company is obligated to pay to an affiliated company up to
            $1,000,000 to meet its financing needs (see Note 15).

      D.    The Company's Israeli subsidiary is party to various litigation
            matters, in most cases involving ordinary and routine claims
            incidental to our business. We cannot estimate with certainty its
            ultimate legal and financial liability with respect to such pending
            litigation matters. However, the Company believes, based on its
            examination of such matters, that the Company's ultimate liability
            will not have a material adverse effect on its financial position,
            results of operations or cash flows.

            as the Company's Chief Financial Officer for a one year term which
            is automatically renewable from year to year unless either party

            one year, following the termination of his employment.

      B.    The Company acquired a 40% interest in a newly established Israeli
            company, Kliks.com Ltd. ("Kliks"), which is engaged in designing and
            establishing a nationwide Screen Phone network in Israel. The
            network will enable Internet access for a wide spread of the
            population who are less familiar with the use of personal computers
            (PC's).
            Top management has been recruited.
            The Company shall be entitled, but not obligated, to purchase up to
            10% of Kliks' share capital upon the payment of $250,000 to Kliks.
            The Company shall pay (by way of equity investment) to Kliks up to
            $1,000,000 to meet the financing needs of Kliks. The Company shall
            not be issued any additional shares or securities of any kind for
            such payments.
            From the period January 2000 to April 2000, the Company paid
            $150,000 as part of this commitment.

      C.    In February 2000, the Company issued $1,000,000, 10% convertible
            debentures to private investors. The debentures were issued pursuant
            to the terms of an agreement which further provides that, subject to
            certain conditions, the investors will purchase an additional
            $1,000,000 of debentures no later than five days after the effective
            date of a registration statement covering the common stock into
            which the debentures may be converted. In January 2000, the
            investors pre-funded $250,000 of this obligation. The debentures
            mature on February 28, 2002.
            The debentures are convertible into shares of the Company's common
            stock at a conversion rate $0.40 per share.

            In connection with the issuance of the 10% convertible debentures,
            the Company issued to debenture holders warrants to purchase, in the
            aggregate, 625,000 of the Company's common shares at an exercise
            price per share of $1. The warrants expire in April 2003. In
            connection with the sale of the convertible debentures the company
            also issued to a consultant warrants to purchase 1.3 million shares
            of common stock. The warrants are exercisable at a price of $1 per
            share and expire in February 2002. The related deferred compensation
            costs of $2.4 million will be amortized over the life of the
            convertible debentures.

      D.    In February 2000 the Company entered into an agreement with a
            certain lender to convert a loan to equity. Principle and interest
            of approximately $700,000 were converted into 3,490,000 shares of
            the Company's common stock.

      E.    The Company entered into various marketing and financial consulting
            agreements in February and March 2000. Under these agreements the
            Company will issue 2,691,000 shares of common stock and pay $8,000
            per month as compensation. The agreements terminate on or before
            March 2001.

            The related compensation costs of $11 million will be allocated to
            the statement of operations in parallel to attainment of the
            service.

      2.1 All meetings of the stockholders for the election of directors shall
be held at the principal office of the corporation, or at such other place
either within or without the State of Delaware as shall be designated from time
to time by the Board and stated in the notice of the meeting. Meetings of
stockholders for any other purpose may be held at such time and place, within or
without the State of Delaware, as shall be stated in the notice of the meeting
or in a duly executed waiver of notice thereof.

      2.2 Annual Meeting. Annual meetings of stockholders shall be held at such
other date and time as shall be designated from time to time by the Board and
stated in the notice of the meeting, at which they shall elect by a Board, and
transact such other business as may properly be brought before the meetings.

      2.3 Special Meetings. Special meetings of the stockholders may be called
for any purpose or purposes, unless otherwise prescribed by statute or by the
Certificate of Incorporation, at the request of the Board, the Chairman of the
Board, the Chief Executive Officer or the stockholders owning a majority in
amount of the entire capital stock of the corporation issued and outstanding and
entitled to vote. Such request shall state the purpose or purposes of the
meeting.

      2.4 Notice of Meetings. Written notice of stockholders' meetings, stating
the place, date and time of the meeting and the purpose or purposes for which
the meeting is called, shall be given to each stockholder entitled to vote at
such meeting on not less than ten (10) nor more than sixty (60) days prior to
the meeting.

      When a meeting is adjourned to another place, date or time, written notice
need not be furnished of the adjourned meeting if the place, date and time
thereof are announced at the meeting at which the adjournment is taken,
provided, however, that if the date of any adjourned meeting is more than thirty
(30) days after the date for which the meeting was
<PAGE>
                                       2


originally noticed, or if a new record date is fixed for the adjourned meeting,
written notice of the place, date and time of the adjourned meeting shall be
furnished in conformity herewith. At any adjourned meeting, any business may be
transacted which might have been transacted at the original meeting.

      2.5 Business Matter of a Special Meeting. Business transacted at a special
meeting of stockholders shall be limited to the purposes stated in the notice.

      2.6 List of Stockholders. The officer who has charge of the stock ledger
of the corporation shall prepare and make, at least ten days before every
meeting of stockholders, a complete list of the stockholders entitled to vote at
the meeting, arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder.
Such list shall be open to the examination of any stockholder, for any purpose
germane to the meeting, during ordinary business hours, for a period of at least
ten days prior to the meeting, either at a place within the city where the
meeting is to be held, which place, if other than the place of the meeting,
shall be specified in the notice of the meeting. The list shall also be produced
and kept at the time and place of the meeting during the whole time thereof, and
may be inspected by any stockholder who is present.

      2.7 Organization and Conduct of Business. The Chairman of the Board, or in
his or her absence, the Chief Executive Officer of the corporation or, in their
absence, such person as the Board may have designated or, in the absence of such
person, such person as may be chosen by the holders of a majority of the shares
entitled to vote who are present, in person or by proxy, shall call to order any
meeting of the stockholders and act as Chairman of the meeting. In the absence
of the Secretary of the corporation, the Secretary of the meeting shall be such
person as the Chairman appoints.

      The chairman of any meeting of the stockholders shall determine the order
of the business and the procedure at the meeting, including such regulation of
the manner of voting and the conduct of the discussion as seems to him or her in
order.

      2.8 Quorum and Adjournments. Except where otherwise provided by law or by
the Certificate of Incorporation or these By-Laws, the holders of a majority of
the stock issued and outstanding and entitled to vote thereto, present in person
or represented by proxy, shall constitute a quorum at all meetings of the
stockholders. The stockholders present at a duly called or held meeting at which
a quorum is present may continue to do business until adjournment,
notwithstanding the withdrawal of enough stockholders to have less than a quorum
if any action taken (other than adjournment) is approved by at least a majority
of the shares required to constitute a quorum. At such adjourned meeting at
which a quorum shall be present or represented, any business may be transacted
which might have been transacted at the meeting as originally notified. If,
however, such quorum shall not be present or represented at any meeting of the
stockholders, the stockholders entitled to vote thereat, present in person or
represented by proxy, shall have power to adjourn the meeting from time to time,
without notice other than announcement at the meeting, until a quorum shall be
present or represented.

      2.9 Voting Rights. Unless otherwise provided in the Certificate of
Incorporation, each stockholder shall at every meeting of the stockholders be
entitled to one vote in person or by proxy for each share of the capital stock
having voting power held by such stockholder.

the holders of a majority of the stock having voting power present in person or
represented by

<PAGE>
                                       3


proxy shall decide any question brought before such meeting, unless the question
is one upon which by express provision of the statutes or the Certificate of
Incorporation or these By-Laws, a different vote is required in which case such
express provision shall govern and control the decision of such question.

      2.11 Record Date for Stockholder Notice and Meeting. For purposes of
determining the stockholders entitled to notice of any meeting or to vote, or
entitled to receive payment of any divided or other distribution, or entitled to
exercise any right in respect of any change, conversion or exchange of stock for
the purpose of any other lawful action, the Board may fix, in advance, a record
date, which shall not be more than sixty (60) nor less than ten (10) days before
any other action.

      If the Board does not fix a record date, the record date of determining
stockholders entitled to notice of or to vote at a meeting of stockholders shall
be at the close of business on the business day next preceding the day on which
notice is given or, if notice is waived, at the close of the business on the
business day next preceding the day on which the meeting is held.

      2.12 Proxies. Every person entitled to vote for directors or any other
matter shall have the right to do so either in person or by one or more agents
authorized by written proxy signed by the person and filed with the Secretary of
the corporation. A proxy shall be deemed signed if the stockholder's name is
placed on the proxy (whether by manual signature, typewriting, telecopier
transmission or otherwise) by the stockholder or the stockholder's
attorney-in-fact. A validly executed proxy which does not state that it is
irrevocable shall continue in full force and effect unless (i) revoked by the
person executing it before the vote pursuant to that proxy, by a writing
delivered to the corporation stating that such proxy is revoked or by a
subsequent proxy executed by, or attendance at the meeting and voting in person
by, the person executing the proxy; or (ii) written notice of the death or
incapacity of the maker of the proxy is received by the corporation before the
vote pursuant to that proxy is counted; provided, however, that no proxy shall
be valid after the expiration of eleven months from the date of the proxy,
unless otherwise provided in the proxy.

      2.13 Action Without a Meeting by Written Consent. All actions required to
be taken at any annual or special meeting of stockholders of the corporation, or
any action which may be taken at any annual or special meeting of such
stockholders, may be taken without a meeting, without prior notice and without a
vote, if consent or consents 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 that action
at a meeting at which all shares entitled to vote thereon were present and voted
and shall be delivered to the corporation by delivery to its registered office,
its principal place of business, or an officer of the corporation having custody
of the book in which proceedings of meetings of stockholders are recorded.

provided in the Certificate of Incorporation. The stockholders may elect a
director or directors at any time to fill a vacancy not filled by the Directors.
If the Board accepts the resignation of a director tendered to take effect at a
future time, the Board shall have the power to elect a successor to take office

<PAGE>
                                       3


      (a) A Shareholder desirous of transferring to others the shares held by
him, in whole or in part (hereinafter the "transferor") shall be obligated to
offer them first to the other Shareholders of the company, by giving notice in
writing to the Shareholders (hereinafter the "sale notice").

      (b) In the sale notice the transferor shall mention the number of shares
he wishes to transfer (hereinafter the "offered shares"), the price forming the
consideration for the offered shares, the name of the offeror (if known at such
time) and the other conditions of the sale.

      (c) The sale notice shall be irrevocable.

      (d) Each one of the shareholders may inform the transferor in writing
within 10 days from the day of receipt of the sale notice as to his desire to
buy the offered shares,, in the price and payment conditions as provided for in
the sale notice (hereinafter the "purchase notice"). A shareholder who has
submitted a purchase notice shall be referred to hereinafter as "buyer".

      (e) Each shareholder shall also have the right of over-allotment such that
if any other shareholder fails to exercise its right to purchase its
proportionate share of such offered shares, each other shareholder may purchase,
on a pro-rata basis, the portion(s) allocable to the non-purchasing
shareholder(s). In the event that any shareholder shall have failed to exercise
its right thereunder by the expiration of the time specified, then, on the
expiration of such time, the transferor shall give each shareholder who has
submitted a purchase notice ("participating buyer") a written notice stating the
amount of shares with respect to which no purchase notice was submitted. Each
participating buyer shall have three (3) days from the date of delivery of such
notice to exercise its right of over-allotment. The process described herein
shall be repeated until (i) purchase notices equal to the abatable amount are
made by participating buyers or (ii) no participating buyer timely exercises its
right of over-allotment.

      (f) If there have been received purchase notices for a total number of
shares equal to the number of offered shares, in that case every buyer shall buy
the number of shares as mentioned in the purchase notice he has submitted.

      (g) If by the end of the time referred to in sub-Section (d) and (e) above
no purchase notices have been received by the transferor or purchase notices for
a total number of shares less than the number of offered shares the transferor
may, within 60 days from expiration of the time for submission of purchase
notices, sell all the offered shares, at a price not less than the price
mentioned in the sale notice and upon all other conditions not less favorable to
the transferor than those provided for in the sale notice. If the transferor
shall not transfer the offered shares as aforesaid, within the aforesaid 60
days, he shall be obligated, before selling the offered shares to another, to
offer them again to the other shareholders in the company in accordance with the
aforesaid procedure, and such procedure shall apply to any further offer.

      (h) If purchase notices shall have been received for a total number of
shares greater than the number of offered shares, the buyers may acquire shares
in a manner proportionate to the share capital of the company held by them at
that time. However, no buyer shall be required to buy a greater number of shares
than the number provided for in the purchase notice submitted by him.

(h), the transferor shall send within 3 days after the last date for submission

                 10% CONVERTIBLE DEBENTURE DUE FEBRUARY 28, 2002

      THIS DEBENTURE is one of a duly authorized issue of up to $2,000,000 in
Debentures of AMBIENT CORPORATION, a corporation organized and existing under
the laws of the State of Delaware (the "Company") designated as its 10%

may have a different maturity date, but which otherwise have substantially
similar terms.

      FOR VALUE RECEIVED, the Company promises to pay to ____________________,
the registered holder hereof (the "Holder"), the principal sum of
_________________________ Dollars (US $__________) on February 28, 2002 (the
"Maturity Date") and to pay interest on the principal sum outstanding from time
to time in arrears (i) prior to the Maturity Date, quarterly, on the last day of
March, June, September and December of each year, (ii) upon conversion as

      This Debenture is subject to the following additional provisions:

      1. The Debentures are issuable in denominations of Twenty-five Thousand
Dollars (US$25,000) and integral multiples thereof. The Debentures are

authorized denominations, as requested by the Holder surrendering the same. No
service charge will be made for such registration or transfer or exchange.

      2. The Company shall be entitled to withhold from all payments of
principal of, and interest on, this Debenture any amounts required to be

                                       1
<PAGE>

such other name does not and will not cause a violation of the Act or any
applicable state or foreign securities laws. Prior to due presentment for
transfer of this Debenture, the Company and any agent of the Company may treat
the person in whose name this Debenture is duly registered on the Company's
Debenture Register as the owner hereof for the purpose of receiving payment as
herein provided and for all other purposes, whether or not this Debenture be
overdue, and neither the Company nor any such agent shall be affected by notice
to the contrary.

      4. A. The Holder of this Debenture is entitled, at its option, subject to
the following provisions of this Section 4, to convert all or a portion of this
Debenture into shares of Common Stock of the Company, $.001 par value per share
("Common Stock") of the Company at any time until the Maturity Date (except as
contemplated by Section 5 hereof), at a conversion price for each share of
Common Stock equal to Forty Cents ($0.40) (the "Conversion Rate"; which amount
is subject to adjustment as hereinafter provided); provided that the principal
amount being converted is the lower of (x) at least Twenty-five Thousand Dollars
[US $25,000] (unless if at the time of such election to convert the aggregate
principal amount of all Debentures registered to the Holder is less than
Twenty-five Thousand Dollars [US $25,000], then the whole amount thereof) or (y)
the maximum amount which the Holder can then convert pursuant to the terms of
Section 4(D) hereof.

            B. Conversion shall be effectuated by surrendering the Debentures to
be converted to the Company or to the Company's transfer agent, North American
Transfer Company, accompanied by or preceded by facsimile or other delivery to
the Company of the form of conversion notice attached hereto as Exhibit A,
executed by the Holder of the Debenture evidencing such Holder's intention to
convert this Debenture or a specified portion hereof, and accompanied, if
required by the Company, by proper assignment hereof in blank. Subject to the
provisions of Section 4(D) hereof, interest accrued or accruing from the date of
issuance to the date of conversion shall, at the option of the Company, be paid
in cash or Common Stock upon conversion at the Conversion Rate applicable to
such conversion. No fractional shares of Common Stock or scrip representing
fractions of shares will be issued on conversion, but the number of shares
issuable shall be rounded to the nearest whole share. The date on which notice
of conversion is given (the "Conversion Date") shall be deemed to be the date on
which the Holder faxes or otherwise delivers the conversion notice ("Notice of
Conversion"), substantially in the form annexed hereto as Exhibit A, duly
executed, to the Company, provided that the Holder shall deliver to the
Company's transfer agent or the Company the original Debentures being converted
within five (5) business days thereafter (and if not so delivered with such
time, the Conversion Date shall be the date on which


                                       2
<PAGE>

the later of the Notice of Conversion and the original Debentures being
converted is received by the Company). Facsimile delivery of the Notice of
Conversion shall be accepted by the Company at facsimile number (0119722)
648-2997; ATTN: Aryeh Weinberg. Certificates representing Common Stock upon
conversion will be delivered within three (3) business days if the address for
delivery is in the United States (and within eight (8) business days if the
address for delivery is outside the United States) from the date later of the
Notice of Conversion is delivered to the Company as contemplated in the first
sentence of this paragraph C or the original Debenture is delivered to the
Company's transfer agent or to the Company.

            C. Anything herein to the contrary notwithstanding, in the event the
Company breaches the provisions of Section 4(g) of the Securities Purchase
Agreement, the Conversion Rate shall be amended to be equal to (i) 90% of (ii)
the Conversion Rate determined in accordance with the other provisions of this
Debenture without regard to this Section 4(C), and the Holder may require the
Company to immediately redeem the outstanding portion of this Debenture in
accordance with clause (y) of Section 6 hereof.

            D. Notwithstanding any other provision hereof, of the Warrants or of
any of the other Transaction Agreements (as those terms are defined in the
Securities Purchase Agreement), in no event (except (i) with respect to an
automatic conversion, if any, of a Debenture as provided in the Debentures or a
conversion pursuant to a Redemption Notice Conversion [as defined below], (ii)
as specifically provided in this Debenture as an exception to this provision, or
(iii) while there is outstanding a tender offer for any or all of the shares of
the Company's Common Stock) shall the Holder be entitled to convert any
Debenture, or shall the Company have the obligation to convert all or any
portion of this Debenture (and the Company shall not have the right to pay
interest on this Debenture), to the extent that, after such conversion, the sum
of (1) the number of shares of Common Stock beneficially owned by the Holder and
its affiliates (other than shares of Common Stock which may be deemed
beneficially owned through the ownership of the unconverted portion of the
Debentures or unexercised portion of the Warrants), and (2) the number of shares
of Common Stock issuable upon the conversion of the Debentures with respect to
which the determination of this proviso is being made, would result in
beneficial ownership by the Holder and its affiliates of more than 9.99% of the
outstanding shares of Common Stock (after taking into account the shares to be
issued to the Holder upon such conversion). For purposes of the proviso to the
immediately preceding sentence, beneficial ownership shall be determined in
accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended
(the "1934 Act"), except as otherwise provided in clause (1) of such sentence.
The Holder, by its acceptance of this Debenture, further agrees that if the
Holder transfers or assigns any of the Debentures to a party who or which would
not be considered such an affiliate, such assignment shall be made subject to
the transferee's or assignee's specific agreement to be bound by the provisions
of this Section 4(D) as if such transferee or assignee were the original Holder
hereof.

      5. A. (i) Notwithstanding any other provision hereof to the contrary, at
any time prior to the Conversion Date, the Company shall have the right to
redeem all or any portion of the then outstanding principal amount of the
Debentures then held by the Holder in cash for an amount (the


                                       3
<PAGE>

"Redemption Amount") equal to the sum of (a) such outstanding principal of the
Debentures plus all accrued but unpaid interest thereon through the date the
Redemption Amount is paid to the Holder (the "Redemption Payment Date"), plus
(b) the Redemption Premium (as defined below).

            (ii) The "Redemption Premium" shall be an amount equal to the
excess, if any, of (a) an amount equal to (I) the number of shares of Common
Stock into which the Holder could have converted the Debentures being redeemed
had the Holder effected such conversion on the Redemption Payment Date,
multiplied by (II) the closing transaction sale price of the Common Stock on the
trading day immediately preceding the Redemption Payment, over (b) the principal
of the Debentures so redeemed.

            (iii) The Company shall give at least ten (10) business days'
written notice of such redemption to the Holder (the "Notice of Redemption").
The date so specified in such Notice of Redemption shall be the Redemption
Payment Date. Anything in the preceding provisions of this Section 5 to the
contrary notwithstanding, the Redemption Amount shall, unless otherwise agreed
to in writing by the Holder after receiving the Notice of Redemption, be paid to
the Holder in good funds at least five (5) but not more than ten (10) business
days from the date of the Notice of Redemption, except that, with respect to any
Debentures for which a Notice of Redemption is given, the Holder shall have the
right, exercisable by giving a Notice of Conversion is submitted to the Company
within five (5) business days of the Holder's receipt of the Company's Notice of
Redemption, to convert any or all of the Debentures sought to be redeemed (a
"Redemption Notice Conversion") and the Redemption Notice Conversion shall take
precedence over the redemption contemplated by the Notice of Redemption. Such
Debentures shall be converted in accordance with the terms hereof. Furthermore,
in the event such Redemption Amount is not timely made, any rights of the
Company to redeem outstanding Debentures shall terminate, and the Notice of
Redemption shall be null and void. Any redemption contemplated by this Debenture
shall be made only in cash by the payment of immediately available good funds to
the Holder.

            B. Any Debentures not previously converted as of the Maturity Date,
shall be deemed to be automatically converted, without further action of any
kind by the Company or any of its agents, employees or representatives, as of
the Maturity Date at the Conversion Rate applicable on the Maturity Date
("Mandatory Conversion").

      6. The Holder recognizes that the Company may be limited in the number of
shares of Common Stock it may issue by (i) reason of its authorized shares, or
(ii) the applicable rules and regulations of the principal securities market on
which the Common Stock is listed or traded (collectively, the"Cap Regulations").
Without limiting the other provisions hereof, (i) the Company will take all
steps reasonably necessary to be in a position to issue shares of Common Stock
on conversion of the Debentures without violating the Cap Regulations and (ii)
if, despite taking such steps, the Company still can not issue such shares of
Common Stock without violating the Cap Regulations, the Holder of this Debenture
(to the extent the same can not be converted in compliance with the Cap
Regulations (an "Unconverted Debenture"), shall have the option, exercisable in
the Holder's sole and absolute discretion, to elect any one of the following
remedies:


                                       4
<PAGE>

            (x) if permitted by the Cap Regulations, require the Company to
      issue shares of Common Stock in accordance with such Holder's Notice of
      Conversion relating to the Unconverted Debenture at a conversion purchase
      price equal to the average of the closing price per share of Common Stock
      for any five (5) consecutive trading days (subject to the equitable
      adjustments for certain events occurring during such period as provided in
      this Debenture) during the sixty (60) trading days immediately preceding
      the date of the Notice of Conversion; or

            (y) require the Company to redeem each Unconverted Debenture for an
      amount (the "Cap Redemption Amount"), payable in cash, equal to:

                         V                      x           M
                  -----------------
                        CP

      where:

            "V" means the outstanding principal plus accrued interest through
      the Cap Redemption Date (as defined below) of an Unconverted Debenture;

            "CP" means the Conversion Rate in effect on the date of redemption
      (the "Cap Redemption Date") specified in the notice from the Holder
      electing this remedy; and

            "M" means the highest closing price during the period beginning on
      the Cap Redemption Date and ending on the date of payment of the Cap
      Redemption Amount.

The holder of an Unconverted Debenture may elect one of the above remedies with
respect to a portion of such Unconverted Debenture and the other remedy with
respect to other portions of the Unconverted Debenture.

      7. Subject to the terms of the Securities Purchase Agreement, dated
February17, 2000 (the "Securities Purchase Agreement"), between the Company and
the Holder (or the Holder's predecessor in interest), no provision of this
Debenture shall alter or impair the obligation of the Company, which is absolute
and unconditional, to pay the principal of, and interest on, this Debenture at
the time, place, and rate, and in the coin or currency, herein prescribed. This
Debenture and all other Debentures now or hereafter issued of similar terms are
direct obligations of the Company.

      8. No recourse shall be had for the payment of the principal of, or the
interest on, this Debenture, or for any claim based hereon, or otherwise in
respect hereof, against any incorporator, shareholder, officer or director, as
such, past, present or future, of the Company or any successor


                                       5
<PAGE>

corporation, whether by virtue of any constitution, statute or rule of law, or
by the enforcement of any assessment or penalty or otherwise, all such liability
being, by the acceptance hereof and as part of the consideration for the issue
hereof, expressly waived and released.

      9. If the Company merges or consolidates with another corporation or sells
or transfers all or substantially all of its assets to another person and the
holders of the Common Stock are entitled to receive stock, securities or
property in respect of or in exchange for Common Stock, then as a condition of
such merger, consolidation, sale or transfer, the Company and any such
successor, purchaser or transferee agree that the Debenture may thereafter be
converted on the terms and subject to the conditions set forth above into the
kind and amount of stock, securities or property receivable upon such merger,
consolidation, sale or transfer by a holder of the number of shares of Common
Stock into which this Debenture might have been converted immediately before
such merger, consolidation, sale or transfer, subject to adjustments which shall
be as nearly equivalent as may be practicable. In the event of any proposed
merger, consolidation or sale or transfer of all or substantially all of the
assets of the Company (a "Sale"), the Holder hereof shall have the right to
convert this Debenture by delivering a Notice of Conversion to the Company
within fifteen (15) days of receipt of notice of such Sale from the Company. In
the event the Holder hereof shall elect not to convert, the Company may (but
shall not be required to) prepay all outstanding principal and accrued interest
on this Debenture by paying the Redemption Amount contemplated by Section 5(A)
hereof, less all amounts required by law to be deducted, upon which tender of
payment following such notice, the right of conversion shall terminate.

      10. If, for any reason, prior to the Conversion Date or the Redemption
Payment Date, the Company spins off or otherwise divests itself of a part of its
business or operations or disposes all or of a part of its assets in a
transaction (the "Spin Off") in which the Company does not receive compensation
(other than nominal non-material compensation) for such business, operations or
assets, but causes securities of another entity (the "Spin Off Securities") to
be issued to security holders of the Company, then the Company shall cause (i)
to be reserved Spin Off Securities equal to the number thereof which would have
been issued to the Holder had all of the Holder's Debentures outstanding on the
record date (the "Record Date") for determining the amount and number of Spin
Off Securities to be issued to security holders of the Company (the "Outstanding
Debentures") been converted as of the close of business on the trading day
immediately before the Record Date (the "Reserved Spin Off Shares"), and (ii) to
be issued to the Holder on the conversion of all or any of the Outstanding
Debentures, such amount of the Reserved Spin Off Shares equal to (x) the
Reserved Spin Off Shares multiplied by (y) a fraction, of which (I) the
numerator is the principal amount of the Outstanding Debentures then being
converted, and (II) the denominator is the principal amount of the Outstanding
Debentures.

      11. If, at any time while any portion of this Debenture remains
outstanding, the Company effectuates a stock split or reverse stock split of its
Common Stock or issues a dividend on its Common Stock consisting of shares of
Common Stock, the Conversion Rate shall be equitably adjusted to reflect such
action. By way of illustration, and not in limitation, of the foregoing (i) if
the Company effectuates a 2:1 split of its Common Stock, thereafter, with
respect to any conversion


                                       6
<PAGE>

for which the Company issues the shares after the record date of such split, the
Conversion Rate shall be deemed to be one-half of what it had been calculated to
be immediately prior to such split; (ii) if the Company effectuates a 1:10
reverse split of its Common Stock, thereafter, with respect to any conversion
for which the Company issues the shares after the record date of such reverse
split, the Conversion Rate shall be deemed to be ten times what it had been
calculated to be immediately prior to such split; and (iii) if the Company
declares a stock dividend of one share of Common Stock for every 10 shares
outstanding, thereafter, with respect to any conversion for which the Company
issues the shares after the record date of such dividend, the Conversion Rate
shall be deemed to be the amount of such Conversion Rate calculated immediately
prior to such record date multiplied by a fraction, of which the numerator is
the number of shares (10) for which a dividend share will be issued and the
denominator is such number of shares plus the dividend share(s) issuable or
issued thereon (11).

      12. All payments contemplated hereby to be made "in cash" shall be made in
immediately available good funds in such coin or currency of the United States
of America as at the time of payment is legal tender for payment of public and
private debts. All payments of cash and each delivery of shares of Common Stock
issuable to the Holder as contemplated hereby shall be made to the Holder at the
address last appearing on the Debenture Register of the Company as designated in
writing by the Holder from time to time; except that the Holder can designate,
by notice to the Company, a different delivery address for any one or more
specific payments or deliveries.

      13. The Holder of the Debenture, by acceptance hereof, agrees that this
Debenture is being acquired for investment and that such Holder will not offer,
sell or otherwise dispose of this Debenture or the Shares of Common Stock
issuable upon conversion thereof except under circumstances which will not
result in a violation of the Act or any applicable state Blue Sky or foreign
laws or similar laws relating to the sale of securities.

      14. This Debenture shall be governed by and construed in accordance with
the laws of the State of Delaware. Each of the parties consents to the
jurisdiction of the federal courts whose districts encompass any part of the
City of Wilmington or the state courts of the State of Delaware sitting in the
City of Wilmington in connection with any dispute arising under this Agreement
and hereby waives, to the maximum extent permitted by law, any objection,
including any objection based on forum non coveniens, to the bringing of any
such proceeding in such jurisdictions. To the extent determined by such court,
the Company shall reimburse the Holder for any reasonable legal fees and
disbursements incurred by the Holder in enforcement of or protection of any of
its rights under any of this Debenture.

      15. The following shall constitute an "Event of Default":

            a.    The Company shall default in the payment of principal or
                  interest on this Debenture and same shall continue for a
                  period of five (5) days; or


                                       7
<PAGE>

            b.    Any of the representations or warranties made by the Company
                  herein, in the Securities Purchase Agreement, the Registration
                  Rights Agreement or in any certificate or financial or other
                  written statements heretofore or hereafter furnished by the
                  Company in connection with the execution and delivery of this
                  Debenture or the Securities Purchase Agreement shall be false
                  or misleading in any material respect at the time made; or

            c.    The Company fails to issue shares of Common Stock to the
                  Holder or to cause its Transfer Agent to issue shares of
                  Common Stock upon exercise by the Holder of the conversion
                  rights of the Holder in accordance with the terms of this
                  Debenture, fails to transfer or to cause its Transfer Agent to
                  transfer any certificate for shares of Common Stock issued to
                  the Holder upon conversion of this Debenture and when required

                  by this Debenture, the Agreement or the Registration Rights

                  such failure shall continue uncured for a period of thirty
                  (30) days after written notice from the Holder of such
                  failure; or

            g.    A trustee, liquidator or receiver shall be appointed for the
                  Company or for a substantial part of its property or business
                  without its consent and shall not be discharged within sixty

            h.    Any governmental agency or any court of competent jurisdiction
                  at the instance of any governmental agency shall assume

            j.    Bankruptcy, reorganization, insolvency or liquidation
                  proceedings or other proceedings for relief under any
                  bankruptcy law or any law for the relief of debtors shall be
                  instituted by or against the Company and, if instituted
                  against the Company, shall not be dismissed within sixty (60)
                  days after such institution or the Company shall by any action
                  or answer approve of, consent to, or acquiesce in any such
                  proceedings or admit the material allegations of, or default
                  in answering a petition filed in any such proceeding; or

            k.    The Company shall have its Common Stock suspended or delisted
                  from an exchange or over-the-counter market from trading for
                  in excess of twenty (20) trading days.

Then, or at any time thereafter, and in each and every such case, unless such
Event of Default shall have been waived in writing by the Holder (which waiver
shall not be deemed to be a waiver of any subsequent default) at the option of
the Holder and in the Holder's sole discretion, the Holder may consider this
Debenture immediately due and payable, without presentment, demand, protest or
notice of any kinds, all of which are hereby expressly waived, anything herein
or in any note or other instruments contained to the contrary notwithstanding,
and the Holder may immediately enforce any and all of the Holder's rights and
remedies provided herein or any other rights or remedies afforded by law.

      16. Nothing contained in this Debenture shall be construed as conferring
upon the Holder the right to vote or to receive dividends or to consent or
receive notice as a shareholder in respect of any meeting of shareholders or any
rights whatsoever as a shareholder of the Company, unless and to the extent
converted in accordance with the terms hereof.

      17. In the event for any reason, any payment by or act of the Company or
the Holder shall result in payment of interest which would exceed the limit
authorized by or be in violation of the law of the jurisdiction applicable to
this Debenture, the ipso facto the obligation of the Company to pay interest or
perform such act or requirement shall be reduced to the limit authorized under
such law, so that in no event shall the Company be obligated to pay any such
interest, perform any such act or be bound by any requirement which would result
in the payment of interest in excess of the limit so authorized. In the event
any payment by or act of the Company shall result in the extraction of a rate of
interest in excess of a sum which is lawfully collectible as interest, then such
amount (to the extent of such excess not returned to the Company) shall, without
further agreement or notice between or by the Company or the Holder, be deemed
applied to the payment of principal, if any, hereunder immediately upon receipt
of such excess funds by the Holder, with the same force and effect as though the
Company had specifically designated such sums to be so applied to principal and
the Holder had agreed to accept such sums as an interest-free prepayment of this
Debenture. If any part of such excess remains after the principal has been paid
in full, whether by the provisions of the preceding sentences of this Section 17
or otherwise, such excess shall be deemed to be an interest-free loan from the
Company to the Holder, which loan shall be payable immediately upon demand by
the Company. The provisions of this Section 17 shall control every other
provision of this Debenture.

      IN WITNESS WHEREOF, the Company has caused this instrument to be duly
executed by an officer thereunto duly authorized.

                                  EXHIBIT 4.2.2

THESE SECURITIES AND THE SECURITIES ISSUABLE UPON THEIR EXERCISE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933 AND MAY NOT BE TRANSFERRED UNLESS
COVERED BY AN EFFECTIVE REGISTRATION STATEMENT UNDER SAID ACT, A TRANSFER
MEETING THE REQUIREMENTS OF RULE 144 OF THE SECURITIES AND EXCHANGE COMMISSION,
OR AN OPINION OF COUNSEL SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY SUCH
TRANSFER IS EXEMPT FROM SUCH REGISTRATION.

                               AMBIENT CORPORATION

                          COMMON STOCK PURCHASE WARRANT

            1. Issuance; Certain Definitions. In consideration of good and
valuable consideration, the receipt of which is hereby acknowledged by AMBIENT
CORPORATION, a Delaware corporation (the "Company"), ____________ or registered
assigns (the "Holder") is hereby granted the right to purchase at any time until
5:00 P.M., New York City time, on February 28, 2003 (the "Expiration Date"),
_______________ (_________) fully paid and nonassessable shares of the Company's
Common Stock, par value $.001 per share (the "Common Stock") at an initial
exercise price per share (the "Exercise Price") of $1.00 per share, subject to
further adjustment as set forth herein. This Warrant is being issued pursuant to
the terms of that certain Securities Purchase Agreement, dated as of February
17, 2000 (the "Securities Purchase Agreement"), to which the Company and Holder
(or Holder's predecessor in interest) are parties.

            2. Exercise of Warrants.

                  2.1 General. This Warrant is exercisable in whole or in part
at any time and from time to time at the Exercise Price per share of Common
Stock payable hereunder, payable in cash or by certified or official bank check,
by means of tendering this Warrant Certificate to the Company. Upon surrender of
this Warrant Certificate with the annexed Notice of Exercise Form duly executed
(which Notice of Exercise Form may be submitted either by delivery to the
Company or by facsimile transmission as provided in Section 8 hereof), together
with payment of the Exercise Price for the shares of Common Stock purchased, the
Holder shall be entitled to receive a certificate or certificates for the shares
of Common Stock so purchased. Anything herein to the contrary notwithstanding,
the provisions of Section 2 of the Joint Escrow Instructions (as defined in the
Securities Purchase Agreement) shall apply to the exercise of this Warrant.

                  2.2 Limitation on Exercise. Notwithstanding the provisions of
this Warrant, the Securities Purchase Agreement or of the other Transaction
Agreements (as defined in the Securities Purchase Agreement), in no event
(except (i) with respect to an automatic conversion, if any, of a Debenture as
provided in the Debentures or a conversion pursuant to a Redemption Notice
Conversion [as defined in the Debentures], (ii) as specifically provided in this
Warrant as an exception to this provision, or (iii) while there is outstanding a
tender offer for any or all of the shares of the Company's Common Stock) shall
the Holder be entitled to exercise this Warrant, or

<PAGE>

shall the Company have the obligation to issue shares upon such exercise of all
or any portion of this Warrant, to the extent that, after such exercise the sum
of (1) the number of shares of Common Stock beneficially owned by the Holder and
its affiliates (other than shares of Common Stock which may be deemed
beneficially owned through the ownership of the unconverted portion of the
Debentures or unexercised portion of the Warrants), and (2) the number of shares
of Common Stock issuable upon the exercise of the Warrants with respect to which
the determination of this proviso is being made, would result in beneficial
ownership by the Holder and its affiliates of more than 9.99% of the outstanding
shares of Common Stock (after taking into account the shares to be issued to the
Holder upon such exercise). For purposes of the proviso to the immediately
preceding sentence, beneficial ownership shall be determined in accordance with
Section 13(d) of the Securities Exchange Act of 1934, as amended (the "1934
Act"), except as otherwise provided in clause (1) of such sentence. The Holder,
by its acceptance of this Warrant, further agrees that if the Holder transfers
or assigns any of the Warrants to a party who or which would not be considered
such an affiliate, such assignment shall be made subject to the transferee's or
assignee's specific agreement to be bound by the provisions of this Section 2.2
as if such transferee or assignee were the original Holder hereof.

            3. Reservation of Shares. The Company hereby agrees that at all
times during the term of this Warrant there shall be reserved for issuance upon
exercise of this Warrant such number of shares of its Common Stock as shall be
required for issuance upon exercise of this Warrant (the "Warrant Shares").

            4. Mutilation or Loss of Warrant. Upon receipt by the Company of
evidence satisfactory to it of the loss, theft, destruction or mutilation of
this Warrant, and (in the case of loss, theft or destruction) receipt of
reasonably satisfactory indemnification, and (in the case of mutilation) upon
surrender and cancellation of this Warrant, the Company will execute and deliver
a new Warrant of like tenor and date and any such lost, stolen, destroyed or
mutilated Warrant shall thereupon become void.

            5. Rights of the Holder. The Holder shall not, by virtue hereof, be
entitled to any rights of a stockholder in the Company, either at law or equity,
and the rights of the Holder are limited to those expressed in this Warrant and
are not enforceable against the Company except to the extent set forth herein.

            6. Protection Against Dilution.

                  6.1 Adjustment Mechanism. If an adjustment of the Exercise
Price is required pursuant to this Section 6, the Holder shall be entitled to
purchase such number of additional shares of Common Stock as will cause (i) the
total number of shares of Common Stock Holder is entitled to purchase pursuant
to this Warrant, multiplied by (ii) the adjusted purchase price per share, to
equal (iii) the dollar amount of the total number of shares of Common Stock
Holder is entitled to purchase before adjustment multiplied by the total
purchase price before adjustment.


                                       2
<PAGE>

                  6.2 Capital Adjustments. In case of any stock split or reverse
stock split, stock dividend, reclassification of the Common Stock,
recapitalization, merger or consolidation, or like capital adjustment affecting
the Common Stock of the Company, the provisions of this Section 6 shall be
applied as if such capital adjustment event had occurred immediately prior to
the date of this Warrant and the original purchase price had been fairly
allocated to the stock resulting from such capital adjustment; and in other
respects the provisions of this Section shall be applied in a fair, equitable
and reasonable manner so as to give effect, as nearly as may be, to the purposes
hereof. A rights offering to stockholders shall be deemed a stock dividend to
the extent of the bargain purchase element of the rights.

                  6.3 Adjustment for Spin Off. If, for any reason, prior to the
exercise of this Warrant in full, the Company spins off or otherwise divests
itself of a part of its business or operations or disposes all or of a part of
its assets in a transaction (the "Spin Off") in which the Company does not
receive compensation (other than nominal non-material compensation) for such
business, operations or assets, but causes securities of another entity (the
"Spin Off Securities") to be issued to security holders of the Company, then the
Company shall cause (a) to be reserved Spin Off Securities equal to the number
thereof which would have been issued to the Holder had all of the Holder's
unexercised Warrants outstanding on the record date (the "Record Date") for
determining the amount and number of Spin Off Securities to be issued to
security holders of the Company (the "Outstanding Warrants") been exercised as
of the close of business on the trading day immediately before the Record Date
(the "Reserved Spin Off Shares"), and (b) to be issued to the Holder on the
exercise of all or any of the Outstanding Warrants, such amount of the Reserved
Spin Off Shares equal to (i) the Reserved Spin Off Shares multiplied by (ii) a
fraction, of which (x) the numerator is the amount of the Outstanding Warrants
then being exercised, and (y) the denominator is the amount of the Outstanding
Warrants.

            7. Transfer to Comply with the Securities Act; Registration Rights.

                  7.1 Transfer. This Warrant has not been registered under the
Securities Act of 1933, as amended, (the "Act") and has been issued to the
Holder for investment and not with a view to the distribution of either the
Warrant or the Warrant Shares. Neither this Warrant nor any of the Warrant
Shares or any other security issued or issuable upon exercise of this Warrant
may be sold, transferred, pledged or hypothecated in the absence of an effective
registration statement under the Act relating to such security or an opinion of
counsel satisfactory to the Company that registration is not required under the
Act. Each certificate for the Warrant, the Warrant Shares and any other security
issued or issuable upon exercise of this Warrant shall contain a legend on the
face thereof, in form and substance satisfactory to counsel for the Company,
setting forth the restrictions on transfer contained in this Section.

                  7.2 Registration Rights. (a) Reference is made to the
Registration Rights Agreement (as that term is defined in the Securities
Purchase Agreement). The Company's


                                       3
<PAGE>

obligations under the Registration Rights Agreement and the other terms and
conditions thereof with respect to the Warrant Shares, including, but not
necessarily limited to, the Company's commitment to file a registration
statement including the Warrant Shares, to have the registration of the Warrant
Shares completed and effective, and to maintain such registration, are
incorporated herein by reference.

                  (b) In addition to the registration rights referred to in the
preceding provisions of Section 7.2(a), effective after the expiration of the
effectiveness of the Registration Statement as contemplated by the Registration
Rights Agreement, the Holder shall have demand piggy-back registration rights
with respect to the Warrant Shares then held by the Holder or then subject to
issuance upon exercise of this Warrant (collectively, the "Remaining Warrant
Shares"), subject to the conditions set forth below. If, at any time after the
Registration Statement has ceased to be effective, the Company participates
(whether voluntarily or by reason of an obligation to a third party) in the
registration of any shares of the Company's stock, the Company shall give
written notice thereof to the Holder and the Holder shall have the right,
exercisable within ten (10) business days after receipt of such notice, to
demand inclusion of all or a portion of the Holder's Remaining Warrant Shares in
such registration statement. If the Holder exercises such election, the
Remaining Warrant Shares so designated shall be included in the registration
statement at no cost or expense to the Holder (other than any costs or
commissions which would be borne by the Holder under the terms of the
Registration Rights Agreement). The Holder's rights under this Section 7.2 are
subject to the following conditions:

      (x) under no circumstances will the Aggregate Remaining Warrant Shares (as
      defined below) included in such registration statement exceed twenty
      percent (20%) of the all the shares (including the Aggregate Remaining
      Warrant Shares) included in such registration statement; and

      (y) if there is a managing underwriter of the offering of shares referred
      to in the registration statement and such managing underwriter advises the
      Company in writing that the number of shares proposed to be included in
      the offering will have an adverse effect on its ability to successfully
      conclude the offering and, as a result, the number of shares to be
      included in the offering is to be reduced, the number of Remaining Warrant
      Shares of the Holder which were to be included in the registration (before
      such reduction) will be reduced pro rata with the number of shares
      included for all other parties whose shares are being registered.

The term "Aggregate Remaining Warrant Shares" means the aggregate of all
Remaining Warrant Shares of the Holder and of the holders of all other Warrants
originally issued pursuant to and as contemplated by the Securities Purchase
Agreement, to the extent such Remaining Warrant Shares are to be included in a
registration statement pursuant to this Section 7.2(b).

                                  EXHIBIT 4.2.3

THESE SECURITIES AND THE SECURITIES ISSUABLE UPON THEIR EXERCISE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933 AND MAY NOT BE TRANSFERRED UNLESS
COVERED BY AN EFFECTIVE REGISTRATION STATEMENT UNDER SAID ACT, A TRANSFER
MEETING THE REQUIREMENTS OF RULE 144 OF THE SECURITIES AND EXCHANGE COMMISSION,
OR AN OPINION OF COUNSEL SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY SUCH
TRANSFER IS EXEMPT FROM SUCH REGISTRATION.

                               AMBIENT CORPORATION

                          COMMON STOCK PURCHASE WARRANT

            1. Issuance; Certain Definitions. In consideration of good and
valuable consideration, the receipt of which is hereby acknowledged by AMBIENT
CORPORATION, a Delaware corporation (the "Company"), ENGLEWOOD HOLDING, INC or
registered assigns (the "Holder") is hereby granted the right to purchase at any
time until 5:00 P.M., New York City time, on February 28, 2002 (the "Expiration
Date"), One Million Three Hundred Thousand (1,300,000) fully paid and
nonassessable shares of the Company's Common Stock, par value $.001 per share
(the "Common Stock") at an initial exercise price per share (the "Exercise
Price") of One Dollar ($1.00), subject to further adjustment as set forth
herein.

            2. Exercise of Warrants.

                  2.1 General. This Warrant is exercisable in whole or in part
at any time and from time to time at the Exercise Price per share of Common
Stock payable hereunder, payable in cash or by certified or official bank check,
by means of tendering this Warrant Certificate to the Company. Upon surrender of
this Warrant Certificate with the annexed Notice of Exercise Form duly executed
(which Notice of Exercise Form may be submitted either by delivery to the
Company or by facsimile transmission as provided in Section 8 hereof), together
with payment of the Exercise Price for the shares of Common Stock purchased, the
Holder shall be entitled to receive a certificate or certificates for the shares
of Common Stock so purchased.

                  2.2 Limitation on Exercise. Notwithstanding the provisions of
this Warrant, in no event (except while there is outstanding a tender offer for
any or all of the shares of the Company's Common Stock) shall the Holder be
entitled to exercise this Warrant, or shall the Company have the obligation, to
issue shares upon such exercise of all or any portion of this Warrant, to the
extent that, after such exercise, the sum of (1) the number of shares of Common
Stock beneficially owned by the Holder and its affiliates (other than shares of
Common Stock which may be deemed beneficially owned through the ownership of the
unexercised portion of the Warrants), and (2) the number of shares of Common
Stock issuable upon the exercise of the Warrants with respect to which the
determination of this proviso is being made, would result in beneficial
ownership by the Holder and its affiliates of more than 4.99% of the outstanding
shares

<PAGE>

of Common Stock (after taking into account the shares to be issued to the Holder
upon such exercise). For purposes of the proviso to the immediately preceding
sentence, beneficial ownership shall be determined in accordance with Section
13(d) of the Securities Exchange Act of 1934, as amended (the "1934 Act"),
except as otherwise provided in clause (1) of such sentence. The Holder, by its
acceptance of this Warrant, further agrees that if the Holder transfers or
assigns any of the Warrants to a party who or which would not be considered such
an affiliate, such assignment shall be made subject to the transferee's or
assignee's specific agreement to be bound by the provisions of this Section 2.2
as if such transferee or assignee were the original Holder hereof.

            3. Reservation of Shares. The Company hereby agrees that at all
times during the term of this Warrant there shall be reserved for issuance upon
exercise of this Warrant such number of shares of its Common Stock as shall be
required for issuance upon exercise of this Warrant (the "Warrant Shares").

            4. Mutilation or Loss of Warrant. Upon receipt by the Company of
evidence satisfactory to it of the loss, theft, destruction or mutilation of
this Warrant, and (in the case of loss, theft or destruction) receipt of
reasonably satisfactory indemnification, and (in the case of mutilation) upon
surrender and cancellation of this Warrant, the Company will execute and deliver
a new Warrant of like tenor and date and any such lost, stolen, destroyed or
mutilated Warrant shall thereupon become void.

            5. Rights of the Holder. The Holder shall not, by virtue hereof, be
entitled to any rights of a stockholder in the Company, either at law or equity,
and the rights of the Holder are limited to those expressed in this Warrant and
are not enforceable against the Company except to the extent set forth herein.

            6. Protection Against Dilution.

                  6.1 Adjustment Mechanism. If an adjustment of the Exercise
Price is required pursuant to this Section 6, the Holder shall be entitled to
purchase such number of additional shares of Common Stock as will cause (i) the
total number of shares of Common Stock Holder is entitled to purchase pursuant
to this Warrant, multiplied by (ii) the adjusted purchase price per share, to
equal (iii) the dollar amount of the total number of shares of Common Stock
Holder is entitled to purchase before adjustment multiplied by the total
purchase price before adjustment.

                  6.2 Capital Adjustments. In case of any stock split or reverse
stock split, stock dividend, reclassification of the Common Stock,
recapitalization, merger or consolidation, or like capital adjustment affecting
the Common Stock of the Company, the provisions of this Section 6 shall be
applied as if such capital adjustment event had occurred immediately prior to
the date of this Warrant and the original purchase price had been fairly
allocated to the stock resulting from such capital adjustment; and in other
respects the provisions of this Section shall be applied in a fair, equitable
and reasonable manner so as to give effect, as nearly as may be, to the purposes
hereof.


                                       2
<PAGE>

A rights offering to stockholders shall be deemed a stock dividend to the extent
of the bargain purchase element of the rights.

                  6.3 Adjustment for Spin Off. If, for any reason, prior to the
exercise of this Warrant in full, the Company spins off or otherwise divests
itself of a part of its business or operations or disposes all or of a part of
its assets in a transaction (the "Spin Off") in which the Company does not
receive compensation (other than nominal non-material compensation) for such
business, operations or assets, but causes securities of another entity (the
"Spin Off Securities") to be issued to security holders of the Company, then the
Company shall cause (a) to be reserved Spin Off Securities equal to the number
thereof which would have been issued to the Holder had all of the Holder's
unexercised Warrants outstanding on the record date (the "Record Date") for
determining the amount and number of Spin Off Securities to be issued to
security holders of the Company (the "Outstanding Warrants") been exercised as
of the close of business on the trading day immediately before the Record Date
(the "Reserved Spin Off Shares"), and (b) to be issued to the Holder on the
exercise of all or any of the Outstanding Warrants, such amount of the Reserved
Spin Off Shares equal to (i) the Reserved Spin Off Shares multiplied by (ii) a
fraction, of which (x) the numerator is the amount of the Outstanding Warrants
then being exercised, and (y) the denominator is the amount of the Outstanding
Warrants.

            7. Transfer to Comply with the Securities Act; Registration Rights.

                  7.1 Transfer. This Warrant has not been registered under the
Securities Act of 1933, as amended, (the "Act") and has been issued to the
Holder for investment and not with a view to the distribution of either the
Warrant or the Warrant Shares. Neither this Warrant nor any of the Warrant
Shares or any other security issued or issuable upon exercise of this Warrant
may be sold, transferred, pledged or hypothecated in the absence of an effective
registration statement under the Act relating to such security or an opinion of
counsel satisfactory to the Company that registration is not required under the
Act. Each certificate for the Warrant, the Warrant Shares and any other security
issued or issuable upon exercise of this Warrant shall contain a legend on the
face thereof, in form and substance satisfactory to counsel for the Company,
setting forth the restrictions on transfer contained in this Section.

                  7.2 Registration Rights. (a) The Company hereby grants to the
Holder piggyback registration rights with respect to the Warrant Shares. In the
event the Company is filing a Registration Statement for itself or on behalf of
any of its shareholders, the Company shall notify the Holder in writing
reasonably in advance of such filing (but at least five business days) and give
the Holder the opportunity to include all or any party of the Warrant Shares
(whether or not previously issued, to the extent permissible under the Act or
any regulation promulgated thereunder. Upon the Holder's notification that the
Holder desires to have all or any portion of the Warrant Shares included in such
registration, the Company shall, at no cost or expense to the Holder, include or
cause to be included in such registration statement the Warrant Shares so
identified by the Holder. The Company's obligations under the foregoing
provisions of this Section 7.2 will be satisfied by


                                       3
<PAGE>

the inclusion of the Warrant Shares in the Registration Statement contemplated
by that certain Registration Rights Agreement, dated as of February 17, 2000
(the "Registration Rights Agreement"), to which the Company and certain
purchasers of the Company's 10% Convertible Debentures are parties, provided
such Registration Statement is declared effective and remains effective for the
term contemplated in the Registration Rights Agreement.

                  (b) In addition to the registration rights referred to in the
preceding provisions of Section 7.2(a), effective after the expiration of the
effectiveness of the Registration Statement as contemplated by the Registration
Rights Agreement, the Holder shall have demand piggy-back registration rights
with respect to the Warrant Shares then held by the Holder or then subject to
issuance upon exercise of this Warrant (collectively, the "Remaining Warrant
Shares"), subject to the conditions set forth below. If, at any time after the
Registration Statement has ceased to be effective, the Company participates
(whether voluntarily or by reason of an obligation to a third party) in the
registration of any shares of the Company's stock, the Company shall give
written notice thereof to the Holder and the Holder shall have the right,
exercisable within ten (10) business days after receipt of such notice, to
demand inclusion of all or a portion of the Holder's Remaining Warrant Shares in
such registration statement. If the Holder exercises such election, the
Remaining Warrant Shares so designated shall be included in the registration
statement at no cost or expense to the Holder (other than any costs or
commissions which would be borne by the Holder under the terms of the
Registration Rights Agreement). The Holder's rights under this Section 7.2(b)
are subject to the following conditions:

      (x) under no circumstances will the Aggregate Remaining Warrant Shares (as
      defined below) included in such registration statement exceed twenty
      percent (20%) of the all the shares (including the Aggregate Remaining
      Warrant Shares) included in such registration statement; and

      (y) if there is a managing underwriter of the offering of shares referred
      to in the registration statement and such managing underwriter advises the
      Company in writing that the number of shares proposed to be included in
      the offering will have an adverse effect on its ability to successfully
      conclude the offering and, as a result, the number of shares to be
      included in the offering is to be reduced, the number of Remaining Warrant
      Shares of the Holder which were to be included in the registration (before
      such reduction) will be reduced pro rata with the number of shares
      included for all other parties whose shares are being registered.

The term "Aggregate Remaining Warrant Shares" means the aggregate of all
Remaining Warrant Shares of the Holder and of the holders of all other Warrants
originally issued pursuant to and as contemplated by the Securities Purchase
Agreement, to the extent such Remaining Warrant Shares are to be included in a
registration statement pursuant to this Section 7.2(b).

            8. Notices. Any notice or other communication required or permitted
hereunder shall be in writing and shall be delivered personally, telegraphed,

offer them first to

<PAGE>
                                       7


the other Shareholders of the company, by giving notice in writing to the
Shareholders (hereinafter the "sale notice").

      (b) In the sale notice the transferor shall mention the number of shares

if any other shareholder fails to exercise its right to purchase its
proportionate share of such offered shares, each other shareholder may purchase,
on a pro-rata basis, the portion(s) allocable to the non-purchasing
shareholder(s). In the event that any shareholder shall have failed to exercise
its right thereunder by the expiration of the time specified, then, on the

made by participating buyers or (ii) no participating buyer timely exercises its
right of over-allotment.

      (f) If there have been received purchase notices for a total number of
shares equal to the number of offered shares, in that case every buyer shall buy
the number of shares as mentioned in the purchase notice he has submitted.

      (g) If by the end of the time referred to in sub-Section (d) and (e) above
no purchase notices have been received by the transferor or purchase notices for
a total number of shares less than the number of offered shares the transferor
may, within 60 days from expiration of the time for submission of purchase
notices, sell all the offered shares, at a price not less than the price
mentioned in the sale notice and upon all other conditions not less favorable to
the transferor than those provided for in the sale notice. If the transferor
shall not transfer the offered shares as aforesaid, within the aforesaid 60
days, he shall be obligated, before selling the offered shares to another, to
offer them again to the other shareholders in the company in accordance with the
aforesaid procedure, and such procedure shall apply to any further offer.

      (h) If purchase notices shall have been received for a total number of
shares greater than the number of offered shares, the buyers may acquire shares
in a manner proportionate to the share capital of the company held by them at
that time. However, no buyer shall be required to buy a greater number of shares
than the number provided for in the purchase notice submitted by him.

relying upon the truth and accuracy of, and the Buyer's compliance with, the
representations, warranties, agreements, acknowledgments and understandings of
the Buyer set forth herein in order to determine the availability of such
exemptions and the eligibility of the Buyer to acquire the Debentures.

            e. The Buyer and its advisors, if any, have been furnished with all
materials relating to the business, finances and operations of the Company and
materials relating to the offer and sale of the Debentures and the offer of the

the Common Stock.

            3. COMPANY REPRESENTATIONS, ETC. The Company represents and warrants
to the Buyer as of the date hereof and as of each Closing Date that, except as
otherwise provided in the relevant Section or paragraph reference in Annex V
hereto (corresponding to the Section or paragraph references below):

            a. Concerning the Debentures and the Shares. There are no preemptive
rights of any stockholder of the Company, as such, to acquire the Debentures,
the Warrants or the Shares. No party has a currently exercisable right of first
refusal which would be applicable to any or all of the transactions contemplated
by the Transaction Agreements.

            b. Reporting Company Status. The Company is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware and has the requisite corporate power to own its properties and to
carry on its business as now being conducted. The Company is duly qualified as a
foreign corporation to do business and is in good standing in each jurisdiction
where the nature of the business conducted or property owned by it makes such
qualification necessary, other than those jurisdictions in which the failure to
so qualify would not have a material adverse effect on the business, operations
or financial condition or results of operation of the Company and its
subsidiaries taken as a whole.. The Company has registered its Common Stock
pursuant to Section 12 of the 1934 Act, and the


                                       5
<PAGE>

Common Stock is listed and traded on The NASDAQ/Bulletin Board Market. The
Company has received no notice, either oral or written, with respect to the
continued eligibility of the Common Stock for such listing, and the Company has
maintained all requirements for the continuation of such listing.

            c. Authorized Shares. The authorized capital stock of the Company
consists of (i) 20,000,000 shares of Common Stock, $.001 par value per share, of
which approximately 8,326,611 shares had been issued as of the date hereof and
(ii) 5,000,000 shares of Preferred Stock, par value $.001 per share, none of
which have been issued as of the date hereof. All issued and outstanding shares
of Common Stock have been duly authorized and validly issued and are fully paid
and nonassessable. The Company has sufficient authorized and unissued shares of
Common Stock as may be necessary to effect the issuance of the Shares. The
Shares have been duly authorized and, when issued upon conversion of, or as
interest on, the Debentures or upon exercise of the Warrants, each in accordance
with its respective terms, will be duly and validly issued, fully paid and
non-assessable and will not subject the holder thereof to personal liability by
reason of being such holder.

            d. Securities Purchase Agreement; Registration Rights Agreement and
Stock. This Agreement and the Registration Rights Agreement, the form of which
is attached hereto as Annex IV (the "Registration Rights Agreement"), and the
transactions contemplated thereby, have been duly and validly authorized by the
Company, this Agreement has been duly executed and delivered by the Company and
this Agreement is, and the Debentures, the Warrants and the Registration Rights
Agreement, when executed and delivered by the Company, will be, valid and
binding agreements of the Company enforceable in accordance with their
respective terms, subject as to enforceability to general principles of equity
and to bankruptcy, insolvency, moratorium, and other similar laws affecting the
enforcement of creditors' rights generally.

            e. Non-contravention. The execution and delivery of this Agreement
and the Registration Rights Agreement by the Company, the issuance of the
Securities, and the consummation by the Company of the other transactions
contemplated by this Agreement, the Registration Rights Agreement, and the
Debentures do not and will not conflict with or result in a breach by the
Company of any of the terms or provisions of, or constitute a default under (i)
the articles of incorporation or by-laws of the Company, each as currently in
effect, (ii) any indenture, mortgage, deed of trust, or other material agreement
or instrument to which the Company is a party or by which it or any of its
properties or assets are bound, including any listing agreement for the Common
Stock except as herein set forth, (iii) to its knowledge, any existing
applicable law, rule, or regulation or any applicable decree, judgment, or order
of any court, United States federal or state regulatory body, administrative
agency, or other governmental body having jurisdiction over the Company or any
of its properties or assets, or (iv) the Company's listing agreement for its
Common Stock, except such conflict, breach or default which would not have a
material adverse effect on the business, operations or financial condition or
results of operations of the Company and its subsidiaries, taken as a whole, or
on the transactions contemplated herein.


                                       6
<PAGE>

            f. Approvals. No authorization, approval or consent of any court,
governmental body, regulatory agency, self-regulatory organization, or stock
exchange or market or the stockholders of the Company is required to be obtained
by the Company for the issuance and sale of the Securities to the Buyer as
contemplated by this Agreement, except such authorizations, approvals and
consents that have been obtained.

            g. SEC Filings. None of the Company's SEC Documents contained, at
the time they were filed, any untrue statement of a material fact or omitted to
state any material fact required to be stated therein or necessary to make the
statements made therein in light of the circumstances under which they were
made, not misleading. The Company has since January 1, 1999 timely filed all
requisite forms, reports and exhibits thereto with the SEC.

            h. Absence of Certain Changes. Since December 31, 1998, there has
been no material adverse change and no material adverse development in the
business, properties, operations, financial condition, or results of operations
of the Company, except as disclosed in the Company's SEC Documents. Since
December 31, 1998, except as provided in the Company's SEC Documents, the
Company has not (i) incurred or become subject to any material liabilities
(absolute or contingent) except liabilities incurred in the ordinary course of

any substantial losses or waived any rights of material value, whether or not in

existing business; (vi) made any changes in employee compensation, except in the
ordinary course of business consistent with past practices; or (vii) experienced
any material problems with labor or management in connection with the terms and
conditions of their employment.

            i. Full Disclosure. There is no fact known to the Company (other
than general economic conditions known to the public generally or as disclosed
in the Company's SEC Documents) that has not been disclosed in writing to the
Buyer that (i) would reasonably be expected to have a material adverse effect on
the business, operations or financial condition of the Company or results of
operations of the Company and its subsidiaries, taken as a whole , (ii) would
reasonably be expected to materially and adversely affect the ability of the
Company to perform its obligations pursuant to this Agreement or any of the
agreements contemplated hereby (collectively, including this Agreement, the
"Transaction Agreements"), or (iii) would reasonably be expected to materially
and adversely affect the value of the rights granted to the Buyer in the
Transaction Agreements.

            j. Absence of Litigation. Except as set forth in the Company's SEC
Documents, there is no action, suit, proceeding, inquiry or investigation before
or by any court,


                                       7
<PAGE>

public board or body pending or, to the knowledge of the Company, threatened
against or affecting the Company, wherein an unfavorable decision, ruling or
finding would have a material adverse effect on the properties, business,
operations or financial condition, or results of operation of the Company and
its subsidiaries taken as a whole or the transactions contemplated by any of the
Transaction Agreements or which would adversely affect the validity or
enforceability of, or the authority or ability of the Company to perform its
obligations under, any of the Transaction Agreements.

            k. Absence of Events of Default. Except as set forth in Section 3(e)
hereof, no Event of Default (or its equivalent term), as defined in the
respective agreement to which the Company is a party, and no event which, with
the giving of notice or the passage of time or both, would become an Event of
Default (or its equivalent term) (as so defined in such agreement), has occurred
and is continuing, which would have a material adverse effect on the business,
operations or the financial condition or results of operations of the Company
and its subsidiaries, taken as a whole.

            l. Prior Issues. During the twelve (12) months preceding the date
hereof, the Company has not issued any convertible securities. The presently
outstanding unconverted principal amount of each such issuance as at February ,
2000 are set forth in Annex V.

            m. No Undisclosed Liabilities or Events. The Company has no
liabilities or obligations other than those disclosed in the Company's SEC
Documents or those incurred in the ordinary course of the Company's business
since December 31, 1998, and which individually or in the aggregate, do not or
would not have a material adverse effect on the properties, business,
operations, financial condition or results of operations of the Company and its
subsidiaries, taken as a whole. No event or circumstances has occurred or exists
with respect to the Company or its properties, business, operations, financial
condition, or results of operations, which, under applicable law, rule or
regulation, requires public disclosure or announcement prior to the date hereof
by the Company but which has not been so publicly announced or disclosed. There
are no proposals currently under consideration or currently anticipated to be
under consideration by the Board of Directors or the executive officers of the
Company which proposal would (x) change the certificate of incorporation or
other charter document or by-laws of the Company, each as currently in effect,
with or without shareholder approval, which change would reduce or otherwise
adversely affect the rights and powers of the shareholders of the Common Stock
or (y) materially or substantially change the business, assets or capital of the
Company, including its interests in subsidiaries.

            n. No Default. The Company is not in default in the performance or
observance of any material obligation, agreement, covenant or condition
contained in any material indenture, mortgage, deed of trust or other material
instrument or agreement to which it is a party or by which it or its property is
bound.

            o. No Integrated Offering. Neither the Company nor any of its
affiliates nor any person acting on its or their behalf has, directly or
indirectly, at any time since December


                                       8
<PAGE>

1, 1998, made any offer or sales of any security or solicited any offers to buy
any security under circumstances that would eliminate the availability of the
exemption from registration under Rule 506 of Regulation D in connection with
the offer and sale of the Securities as contemplated hereby.

            p. Dilution. The number of Shares issuable upon conversion of the
Debentures and the exercise of the Warrants may increase substantially in
certain circumstances, including, but not necessarily limited to, the
circumstance wherein the trading price of the Common Stock declines prior to the
conversion of the Debentures. The Company's executive officers and directors
have studied and fully understand the nature of the Securities being sold hereby
and recognize that they have a potential dilutive effect. The board of directors
of the Company has concluded, in its good faith business judgment, that such
issuance is in the best interests of the Company. The Company specifically
acknowledges that its obligation to issue the Shares upon conversion of the
Debentures and upon exercise of the Warrants is binding upon the Company and
enforceable regardless of the dilution such issuance may have on the ownership
interests of other shareholders of the Company.

            r. Brokers, Finders. Except for payment of fees to Burstein &
Lindsay Securities Corp. (the "Placement Agent"), payment of which is the sole
responsibility of the Company, the Company has taken no action which would give
rise to any claim by any person for brokerage commission, finder's fees or
similar payments by Buyer relating to this Agreement or the transactions
contemplated hereby. Buyer shall have no obligation with respect to such fees or
with respect to any claims made by or on behalf of other Persons for fees of a
type contemplated in this Section 3(r) that may be due in connection with the
transactions contemplated hereby. The Company shall indemnify and hold harmless
each of Buyer, its employees, officers, directors, agents, and partners, and
their respective affiliates, from and against all claims, losses, damages, costs
(including the costs of preparation and attorney's fees) and expenses suffered
in respect of any such claimed or existing fees, as and when incurred.

            4. CERTAIN COVENANTS AND ACKNOWLEDGMENTS.

            a. Transfer Restrictions. The Buyer acknowledges that (1) the
Debentures have not been and are not being registered under the provisions of
the 1933 Act and, except as provided in the Registration Rights Agreement, the
Shares have not been and are not being registered under the 1933 Act, and may
not be transferred unless (A) subsequently registered thereunder or (B) the
Buyer shall have delivered to the Company an opinion of counsel, reasonably
satisfactory in form, scope and substance to the Company, to the effect that the
Securities to be sold or transferred may be sold or transferred pursuant to an
exemption from such registration; (2) any sale of the Securities made in
reliance on Rule 144 promulgated under the 1933 Act may be made only in
accordance with the terms of said Rule and further, if said Rule is not
applicable, any resale of such Securities under circumstances in which the
seller, or the person through whom the sale is made, may be deemed to be an
underwriter, as that term is used in the 1933 Act, may require compliance with
some other exemption under the 1933 Act or the rules and regulations of the SEC
thereunder; and (3) neither the Company nor any other


                                       9
<PAGE>

person is under any obligation to register the Securities (other than pursuant
to the Registration Rights Agreement) under the 1933 Act or to comply with the
terms and conditions of any exemption thereunder.

            b. Restrictive Legend. The Buyer acknowledges and agrees that the
Debentures and the Warrants, and, until such time as the Common Stock has been
registered under the 1933 Act as contemplated by the Registration Rights
Agreement and sold in accordance with an effective Registration Statement,
certificates and other instruments representing any of the Securities shall bear
a restrictive legend in substantially the following form (and a stop-transfer
order may be placed against transfer of any such Securities):

            THESE SECURITIES (THE "SECURITIES") HAVE NOT BEEN REGISTERED UNDER
            THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR
            THE SECURITIES LAWS OF ANY STATE AND MAY NOT BE SOLD OR OFFERED FOR
            SALE IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE
            SECURITIES OR AN OPINION OF COUNSEL OR OTHER EVIDENCE ACCEPTABLE TO
            THE CORPORATION THAT SUCH REGISTRATION IS NOT REQUIRED.

            c. Registration Rights Agreement. The parties hereto agree to enter
into the Registration Rights Agreement on or before the Closing Date.

            d. Filings. The Company undertakes and agrees to make all necessary
filings in connection with the sale of the Securities to the Buyer under any
United States laws and regulations applicable to the Company, or by any domestic
securities exchange or trading market, and to provide a copy thereof to the
Buyer promptly after such filing.

            e. Reporting Status. So long as the Buyer beneficially owns any of
the Securities, the Company shall file all reports required to be filed with the
SEC pursuant to Section 13 or 15(d) of the 1934 Act, and the Company shall not
terminate its status as an issuer required to file reports under the 1934 Act
even if the 1934 Act or the rules and regulations thereunder would permit such
termination. The Company will take all reasonable action under its control to
obtain and to continue the listing and trading of its Common Stock (including,
without limitation, all Registrable Securities) on The NASDAQ/Bulletin Board
Market and will comply in all material respects with the Company's reporting,
filing and other obligations under the by-laws or rules of the National
Association of Securities Dealers, Inc. ("NASD") or The NASDAQ/Bulletin Board
Market.

            f. Use of Proceeds. The Company will use the proceeds from the sale
of the Debentures (excluding amounts paid by the Company for legal fees,
finder's fees and escrow fees in connection with the sale of the Debentures) for
internal working capital purposes, and, unless specifically consented to in
advance in each instance by the Buyer, the Company shall not, directly or
indirectly, use such proceeds for any loan to or investment in any other


                                       10
<PAGE>

corporation, partnership enterprise or other person or for the repayment of any
outstanding loan by the Company to any other party.

            g. Certain Agreements. (i) Except to the extent specifically
provided below, but in each such event subject to compliance with all of the
other provisions of this Agreement, the Company covenants and agrees that it
will not, without the prior written consent of the Buyer, enter into any
subsequent or further offer or sale of Common Stock or securities convertible
into Common Stock (collectively, "New Common Stock") with any third party
pursuant to a transaction which in any manner permits the sale of the New Common
Stock on any date which is earlier than one hundred eighty (180) days after the
Effective Date.

            (ii) The provisions of subparagraph (g)(i) will not apply to (x) the
issuance of securities (other than for cash) in connection with an acquisition,
merger, consolidation, or a sale or disposition of assets, or (y) the exchange
of the capital stock for assets, stock or other joint venture interests;
provided, however, that any action contemplated under this subparagraph (g)(ii)
is subject to the condition that registration rights, if any, in connection with
such action shall not require the filing of a Registration Statement in respect
of such stock prior to one hundred eighty (180) days after the Effective Date.

            (iii) The provisions of subparagraph (g)(i) will also not apply to
(x) the issuance of securities to a Strategic Partner (except that the
provisions of subparagraph g(iv) shall apply with respect to the issuance of
such securities to the Strategic Partner) and (y) the issuance of securities to
employees of the Company under the Company's ESOP in existence on the date
hereof.

            (iv) Within ten (10) business days after the Initial Closing Date,
the Company shall obtain the agreement (each, a "Principal's Agreement") of each
of its Principals (as defined below) that, without the prior written consent of
the Buyer in each instance, such Principal will not sell or otherwise transfer
or offer to sell or otherwise transfer (except in a private transaction in which
the transferee agrees in writing for the benefit of Buyer and enforceable by
Buyer, a copy of which written agreement is provided to Buyer, to be bound by
the provisions of the Principal's Agreement as if such transferee were a
Principal) any shares of Common Stock directly or indirectly held by such
Principal prior to one hundred eighty (180) days after the Effective Date. Each
such Principal's Agreement shall (w) specify that it is entered into as an
inducement to the Buyer's execution, delivery and performance of this Agreement,
(x) name the Buyer as a third party beneficiary thereof, (y) acknowledge that
the Company's transfer agent will be provided with instructions that transfers
by a Principal require the consent of the Company and the Buyer, and (z)
contemplate that, in addition to any other damages or remedies that may be
appropriate, the Principal's Agreement shall be enforceable by injunction sought
by the Company and the Buyer or any one or more of them. A "Principal" is a
person who meets any one or more of the following criteria: (A) a person who is
a director or principal officer of the Company (each, a "Company Principal") and
who, directly or indirectly, holds any shares of Common Stock of the Company;
(B) a spouse of a Company Principal (a "Principal's Spouse") who, directly or
indirectly, holds any shares of Common Stock of the Company, (C) a parent,


                                       11
<PAGE>

sibling or child of a Company Principal who resides in the household of a
Company Principal or of a Principal's Spouse (each, a "Principal's Relative")
and who, directly or indirectly, holds any shares of Common Stock, (D) any other
person or entity, including, without limitation, for profit or non-profit
corporations, partnerships and trusts, whose voting rights regarding Common
Stock of the Company is subject to the direction, control or other influence of
any Company Principal, Principal's Spouse, or Principal's Relative, or (E) a
Strategic Partner and any person or entity controlled by or in control of such
Strategic Partner. If the Company enters into an agreement with a Strategic
Partner after the date hereof, the Company shall obtain the Principal's
Agreement from the parties contemplated by clause (E) of the immediately
preceding sentence simultaneously with the closing of such agreement. Anything
in the preceding provisions of this subparagraph (iv) to the contrary
notwithstanding, Buyer agrees that each of Aryeh Weinberg and Michael Braunold
may exclude 25,000 shares of the Company's Common Stock currently held by him
from his Principal's Agreement.

            (v) In the event the Company breaches the provisions of this Section
4(g), the Conversion Rate (as defined in the Debentures) shall be amended to be
equal to (x) 90% of (y) the amount determined in accordance with the provisions
of the Debenture without regard to this provision, and the Purchaser may require
the Company to immediately redeem all outstanding Debentures in accordance with
Section 4(j)(y) hereof.

            h. Available Shares. The Company shall have at all times authorized
and reserved for issuance, free from preemptive rights, shares of Common Stock
sufficient to yield two hundred percent (200%) of the number of shares of Common
Stock issuable (i) at conversion as may be required to satisfy the conversion
rights of the Buyer pursuant to the terms and conditions of the Debentures and
(ii) upon exercise as may be required to satisfy the exercise rights of the
Buyer pursuant to the terms and conditions of the Warrants.

            i. Warrants. The Company agrees to issue to the Buyer on each
Closing Date transferable, divisible warrants (the "Warrants") for the purchase
of six thousand two hundred fifty (6,250) shares of Common Stock for ten
thousand dollars ($10,000) of Purchase Price for the Debentures issued on that
date. The Warrants attributable to each such conversion shall bear an exercise
price One Dollar ($1.00) per share (subject to adjustment as provided in the
Warrant). The Warrants will expire on the last day of the calendar month in
which the third anniversary of the relevant Closing Date occurs. The Warrants
shall be in the form annexed hereto as Annex VI, together with (x) registration
rights as provided in the Registration Rights Agreement and (y) piggy-back
registration rights after the effectiveness of the Registration Statement
expires, as contemplated by the Registration Rights Agreement.

            j. Limitation on Issuance of Shares. The Company may be limited in
the number of shares of Common Stock it may issue by virtue of (i) the number of
authorized shares or (ii) the applicable rules and regulations of the principal
securities market on which the Common Stock is listed or traded, including, but
not necessarily limited to, NASDAQ Rule 4310(c)(25)(H)(i)(d)(2) (collectively,
the "Cap Regulations"). Without limiting the other provisions thereof, the
Debentures shall provide that (i) the Company will take all steps


                                       12
<PAGE>

reasonably necessary to be in a position to issue shares of Common Stock on
conversion of the Debentures without violating the Cap Regulations and (ii) if,
despite taking such steps, the Company still can not issue such shares of Common
Stock without violating the Cap Regulations, the holder of a Debenture which can
not be converted as result of the Cap Regulations (each such Debenture, an
"Unconverted Debenture") shall have the option, exercisable in such holder's
sole and absolute discretion, to elect either of the following remedies:

            (x) if permitted by the Cap Regulations, require the Company to
      issue shares of Common Stock in accordance with such holder's notice of
      conversion at a conversion purchase price equal to the average of the
      closing price per share of Common Stock for any five (5) consecutive
      trading days (subject to certain equitable adjustments for certain events
      occurring during such period) during the sixty (60) trading days
      immediately preceding the date of notice of conversion; or

            (y) require the Company to redeem each Unconverted Debenture for an
      amount (the "Redemption Amount"), payable in cash, equal to:

                          V                      x           M
                  -----------------
                         CP

      where:

            "V" means the principal of an Unconverted Debenture plus any accrued
      but unpaid interest thereon;

            "CP" means the conversion price in effect on the date of redemption
      (the "Redemption Date") specified in the notice from the holder of the
      Unconverted Debentures electing this remedy; and

            "M" means the highest closing price per share of the Common Stock
      during the period beginning on the Redemption Date and ending on the date
      of payment of the Redemption Amount.

A holder of an Unconverted Debenture may elect one of the above remedies with
respect to a portion of such Unconverted Debenture and the other remedy with
respect to other portions of the Unconverted Debenture. The Debentures shall
contain provisions substantially consistent with the above terms, with such
additional provisions as may be consented to by the Buyer. The provisions of
this paragraph are not intended to limit the scope of the provisions otherwise
included in the Debentures.

            k. Hedging Transactions. (i) The Company understands that the Buyer
may be a so-called "hedge" fund, and the Company hereby expressly agrees that,
except as provided in subparagraph (ii) of this paragraph (k), the Buyer shall
not in any way be prohibited

<PAGE>

or restricted from any purchases or sales of any securities or other instruments
of, or related to, the Company or any of its securities, including, but not
necessarily limited to, puts, calls, futures contracts, short sales and hedging
and arbitrage transactions. The Buyer acknowledges that such purchases, sales
and other transactions may be subject to various federal and state securities
laws and agrees to comply with all such applicable securities laws.

            (ii) The Buyer agrees that, prior to the Effective Date, the Buyer
will not engage in any puts, calls, futures contracts, short sales and hedging
and arbitrage transactions with respect to the Common Stock.

            l. Right of First Refusal. (i) The Company covenants and agrees that
if during the period from the date hereof through and including the date which
is two hundred seventy (270) days after the Effective Date, the Company offers
to enter into any transaction other than with a Strategic Partner (a "New
Transaction") for the sale of New Common Stock, the Company shall notify the
Buyer in writing of all of the terms of such offer (a "New Transaction Offer").
The Buyer shall have the right (the "Right of First Refusal"), exercisable by
written notice given to the Company by the close of business on the fifth
business day after the Buyer's receipt of the New Transaction Offer (the "Right
of First Refusal Expiration Date"), to participate in all or any part of the New
Transaction Offer on the terms so specified.

            (ii) If, and only if, the Buyer does not exercise the Right of First
Refusal in full, the Company may consummate the remaining portion of the New
Transaction with any New Investor on the terms specified in the New Transaction
Offer within thirty (30) days of the Right of First Refusal Expiration Date.

            (iii) If the terms of the New Transaction to be consummated with
such other party differ from the terms specified in the New Transaction Offer so
that the terms are more beneficial in any respect to the New Investor, the
Company shall give the Buyer a New Transaction Offer relating to the terms of
the New Transaction, as so changed, and the Buyer's Right of First Refusal and
the preceding terms of this paragraph (l) shall apply with respect to such
changed terms.

            (iv) If there is more than one Buyer signatory to this Agreement,
the preceding provisions of this paragraph (l) shall apply pro rata among them
(based on their relative Buyer's Allocable Shares), except that, to the extent
any such Buyer does not exercise its Right of First Refusal in full (a
"Declining Buyer"), the remaining Buyer or Buyers who or which have exercised
their own Right of First Refusal in full, shall have the right (pro rata among
them based on their relative Buyer's Allocable Shares, if more than one) to
exercise all or a portion of such Declining Buyer's unexercised Right of
Refusal. Nothing in this paragraph (l) shall be deemed to permit a transaction
not otherwise permitted by subparagraph (g)(i), as modified by the provisions of
subparagraph (g)(ii).

            (v) In the event the New Transaction is consummated with such other
third party at any time prior to the expiration of ninety (90) days after the

for (x) either a sale price equal to or computed based on, or a determination of
a conversion price based on, a lower percentage of the then current market price
(howsoever defined or computed) than provided in the Debentures for determining,
the Conversion Rate (howsoever defined or computed) and/or (y) the issuance of
warrants at an exercise price lower than that provided in the Warrants, the
terms of any unissued or unconverted Debentures or any unissued or unexercised
Warrants shall be modified to reduce the relevant Conversion Rate or Warrant

consummated.

            m. Certain Transfers Require Consent of Company. Anything in the
other provisions of this Agreement or any of the other Transaction Agreements to
the contrary notwithstanding, in no event shall any one or more of the Buyers
individually or collectively transfer any of the Debentures, Shares, Warrants or
Warrant Shares to any party except (i) in an ordinary bona fide arm's-length
over-the-counter or other established market transaction, (ii) provided the
transferee in such transaction agrees in writing in favor of the Company and
enforceable by the Company, a copy of which writing shall be provided to the
Company, to be bound by the provisions of this paragraph, to a relative or
affiliate of the Buyer or (iii) with the prior written consent of the Company,
which consent the Company agrees not to unreasonably withhold or delay. The
provisions of this paragraph shall not be read in any way to limit any other
rights the Buyer may have under the Transaction Agreements , including but not
limited to the right to convert the Debentures as contemplated therein and in
this Agreement.

            5. TRANSFER AGENT INSTRUCTIONS.

            a. Promptly following the delivery by the Buyer of the Purchase
Price for the Initial Debentures in accordance with Section 1(c) hereof, the
Company will irrevocably instruct its transfer agent to issue Common Stock from
time to time upon conversion of the Debentures in such amounts as specified from
time to time by the Company to the transfer agent, bearing the restrictive
legend specified in Section 4(b) of this Agreement prior to registration of the
Shares under the 1933 Act, registered in the name of the Buyer or its nominee
and in such denominations to be specified by the Buyer in connection with each
conversion of the Debentures. The Company warrants that no instruction
inconsistent with the instructions referred to in this Section 5 and the stop
transfer instructions to give effect to Section 4(a) hereof prior to
registration and sale of the Shares under the 1933 Act will be given by the
Company to the transfer agent with respect to the Shares and that the Shares
shall otherwise be freely transferable on the books and records of the Company
as and to the extent provided in this Agreement, the Registration Rights
Agreement, and applicable law. Nothing in this Section shall affect in any way
the Buyer's obligations and agreement to comply with all applicable securities
laws upon resale of the Securities. If the Buyer provides the Company with an
opinion of counsel reasonably satisfactory to the Company that registration of a
resale by the Buyer of any of the Securities in accordance with clause (1)(B) of
Section 4(a) of this Agreement is not required under the 1933 Act, the Company
shall (except as provided in clause (2) of Section 4(a) of this Agreement)
permit the transfer of the Securities and, in the case of the Converted Shares
or the Warrant Shares, as the case may be, promptly instruct the Company's
transfer agent to issue one or more certificates for Common Stock without legend
in such name and in such

<PAGE>

denominations as specified by the Buyer.

            b. (i) The Company will permit the Buyer to exercise its right to
convert the Debentures by telecopying or delivering an executed and completed
Notice of Conversion to the Company and delivering, within five (5) business
days thereafter, the original Debentures being converted to the Company by
express courier, with a copy to the transfer agent.

               (ii) The term "Conversion Date" means, with respect to any
conversion elected by the holder of the Debentures, the date specified in the
Notice of Conversion, provided the copy of the Notice of Conversion is
telecopied to or otherwise delivered to the Company in accordance with the
provisions hereof so that it is received by the Company on or before such
specified date.

               (iii) The Company will transmit the certificates representing the
Converted Shares issuable upon conversion of any Debentures (together, unless
otherwise instructed by the Buyer, with Debentures not being so converted) to
the Buyer at the address specified in the Notice of Conversion (which may be the
Buyer's address for notices as contemplated by Section 11 hereof or a different
address) via recognized express or overnight courier, by electronic transfer or
otherwise, within three (3) business days if the address for delivery is in the
United States and within eight (8) business days if the address for delivery is
outside the United States (such third business day or eighth business day, as
the case may be, the "Delivery Date") after (A) the business day on which the
Company has received both of the Notice of Conversion (by facsimile or other
delivery) and the original Debentures being converted (and if the same are not
delivered to the Company on the same date, the date of delivery of the second of
such items) or (B) the date an interest payment on the Debenture, which the
Company has elected to pay by the issuance of Common Stock, as contemplated by
the Debentures, was due.

            c. The Company understands that a delay in the issuance of the
Shares of Common Stock beyond the Delivery Date could result in economic loss to
the Buyer. As compensation to the Buyer for such loss, the Company agrees to pay
late payments to the Buyer for late issuance of Shares upon Conversion in
accordance with the following schedule (where "No. Business Days Late" is
defined as the number of business days beyond two (2) business days from the
Delivery Date):

                                              Late Payment For Each $10,000
                                              of Debenture Principal or Interest
                  No. Business Days Late      Amount Being Converted
                  --------------------------------------------------------------
                        1                             $100
                        2                             $200
                        3                             $300
                        4                             $400
                        5                             $500

<PAGE>

                        6                             $600
                        7                             $700
                        8                             $800
                        9                             $900
                        10                            $1,000
                        >10                           $1,000 +$200 for each
                                                      Business Day Late beyond
                                                      10 days

The Company shall pay any payments incurred under this Section in immediately
available funds upon demand. Nothing herein shall limit the Buyer's right to
pursue actual damages for the Company's failure to issue and deliver the Common
Stock to the Buyer. Furthermore, in addition to any other remedies which may be
available to the Buyer, in the event that the Company fails for any reason to
effect delivery of such shares of Common Stock within two (2) business days
after the Delivery Date, the Buyer will be entitled to revoke the relevant
Notice of Conversion by delivering a notice to such effect to the Company
whereupon the Company and the Buyer shall each be restored to their respective
positions immediately prior to delivery of such Notice of Conversion.

            d. If, by the relevant Delivery Date, the Company fails for any
reason to deliver the Shares to be issued upon conversion of a Debenture and
after such Delivery Date, the holder of the Debentures being converted (a
"Converting Holder") purchases, in an arm's-length open market transaction or
otherwise, shares of Common Stock (the "Covering Shares") in order to make
delivery in satisfaction of a sale of Common Stock by the Converting Holder (the
"Sold Shares"), which delivery such Converting Holder anticipated to make using
the Shares to be issued upon such conversion (a "Buy-In"), the Company shall pay
to the Converting Holder, in addition to all other amounts contemplated in other
provisions of the Transaction Agreements, and not in lieu thereof, the Buy-In
Adjustment Amount (as defined below). The "Buy-In Adjustment Amount" is the
amount equal to the excess, if any, of (x) the Converting Holder's total
purchase price (including brokerage commissions, if any) for the Covering Shares
over (y) the net proceeds (after brokerage commissions, if any) received by the
Converting Holder from the sale of the Sold Shares. The Company shall pay the
Buy-In Adjustment Amount to the Company in immediately available funds
immediately upon demand by the Converting Holder. By way of illustration and not
in limitation of the foregoing, if the Converting Holder purchases shares of
Common Stock having a total purchase price (including brokerage commissions) of
$11,000 to cover a Buy-In with respect to shares of Common Stock it sold for net
proceeds of $10,000, the Buy-In Adjustment Amount which Company will be required
to pay to the Converting Holder will be $1,000.

            e. In lieu of delivering physical certificates representing the
Common Stock issuable upon conversion, provided the Company's transfer agent is
participating in the Depository Trust Company ("DTC") Fast Automated Securities
Transfer program, upon request of the Buyer and its compliance with the
provisions contained in this paragraph, so long as the certificates therefor do
not bear a legend and the Buyer thereof is not obligated to return such

<PAGE>

certificate for the placement of a legend thereon, the Company shall use its
best efforts to cause its transfer agent to electronically transmit the Common
Stock issuable upon conversion to the Buyer by crediting the account of Buyer's
Prime Broker with DTC through its Deposit Withdrawal Agent Commission system.

            f. The Company will authorize its transfer agent to give information
relating to the Company directly to the Buyer or the Buyer's representatives
designated by the Buyer in writing to the Company upon the request of the Buyer
or any such representative. The Company will provide the Buyer with a copy of
the authorization so given to the transfer agent.

            6. CLOSING DATES.

            a. The Initial Closing Date shall occur on the date which is the
first NYSE trading day after each of the conditions contemplated by Sections 7

the SEC (on the SEC's EDGAR system) in which the Company specifies as the
Additional Closing Date a business day which is at least forty-five (45) days

specifies the the number of business days after the actual Effective Date, which
number shall be at least two (2) and not more than five (5), on which the
Additional Closing Date is to occur. If an Effectiveness Closing Date Notice is

fax transmission or hand delivery and (y) by telephone communication of the
actual Effective Date declared by the SEC no later than noon on the business day
after such Effective Date.

               (iv) The term "Effectiveness Request" means the Company's written
request to the SEC that the SEC declare the Registration Statement effective on

the Effectiveness Request shall be given only after the SEC has advised the
Company informally, in writing or otherwise that it will respond favorably to
such request.

               (v) The closing for the Additional Debentures shall be conducted
upon the same terms and conditions as those applicable to the Initial
Debentures.

               (vi) The Buyer agrees that, anything in Section 10 hereof to the

shall be deemed properly given to the Buyer if such notice is given in the
manner contemplated by this Section 6(b) to Advisor Associates, Inc., 1575 45th
Street, Brooklyn, NY 11219, Attn: Nourit Bassiri, telephone no. (718) 972-6400,

to others and to release the other Escrow Property on the relevant Closing Date
upon satisfaction of the conditions set forth in Sections 7 and 8 hereof and as

                          REGISTRATION RIGHTS AGREEMENT

            THIS REGISTRATION RIGHTS AGREEMENT, dated as of February 17, 2000
(this "Agreement"), is made by and between AMBIENT CORPORATION, a Delaware
corporation, with headquarters located at 270 Madison Avenue, New York, NY 10016
(the "Company"), and each entity named on a signature page hereto (each, an
"Initial Investor") (each agreement with an Initial Investor being deemed a
separate and independent agreement between the Company and such Initial
Investor, except that each Initial Investor acknowledges and consents to the
rights granted to each other Initial Investor under such agreement).

                              W I T N E S S E T H:

            WHEREAS, upon the terms and subject to the conditions of the
Securities Purchase Agreement, dated as of February 15, 2000, between the
Initial Investor and the Company (the "Securities Purchase Agreement"; terms not
otherwise defined herein shall have the meanings ascribed to them in the
Securities Purchase Agreement), the Company has agreed to issue and sell to the
Initial Investor one or more 10% Convertible Debentures of the Company, in an
aggregate principal amount not exceeding $2,000,000 (the "Debentures"); and

            WHEREAS,  the  Company  has  agreed to issue the  Warrants  to the
Initial Investor in connection with the issuance of the Debentures; and

            WHEREAS, the Debentures are convertible into shares of Common Stock
(the "Conversion Shares"; which term, for purposes of this Agreement, shall
include shares of Common Stock of the Company issuable in lieu of accrued
interest on conversion as contemplated by the Debentures) upon the terms and
subject to the conditions contained in the Debentures and the Warrants may be
exercised for the purchase of shares of Common Stock (the "Warrant Shares") upon
the terms and conditions of the Warrants; and

            WHEREAS, to induce the Initial Investor to execute and deliver the
Securities Purchase Agreement, the Company has agreed to provide certain
registration rights under the Securities Act of 1933, as amended, and the rules
and regulations thereunder, or any similar successor statute (collectively, the
"Securities Act"), with respect to the Conversion Shares and the Warrant Shares;

            NOW, THEREFORE, in consideration of the premises and the mutual
covenants contained herein and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the Company and the
Initial Investor hereby agree as follows:

1.                Definitions.      As used in this  Agreement,  the following
terms shall have the following meanings:

Registrable Securities.
4.
5. (b) "Potential Material Event" means any of the following: (i) the possession
by the Company of material information not ripe for disclosure in a registration
statement, which shall be evidenced by determinations in good faith by the Board
of Directors of the Company that disclosure of such information in the
registration statement would be detrimental to the business and affairs of the
Company; or (ii) any material engagement or activity by the Company which would,
in the good faith determination of the Board of Directors of the Company, be
adversely affected by disclosure in a registration statement at such time, which
determination shall be accompanied by a good faith determination by the Board of
Directors of the Company that the registration statement would be materially
misleading absent the inclusion of such information.
6.
7. (c) "Register," "Registered," and "Registration" refer to a registration
effected by preparing and filing a Registration Statement or Statements in
compliance with the Securities Act and pursuant to Rule 415 under the Securities
Act or any successor rule providing for offering securities on a continuous
basis ("Rule 415"), and the declaration or ordering of effectiveness of such
Registration Statement by the United States Securities and Exchange Commission
(the "SEC").
8.
9. (d) "Registrable Securities" means the Conversion Shares and the Warrant
Shares.
10.
11. (e) "Registration Statement" means a registration statement of the Company

16.
(One) Mandatory Registration.
(Two)
(Three) (i) The Company shall prepare and file with the SEC, as soon as possible
after the Initial Closing Date but no later than a date (the "Required Filing
Date") which is forty-five (45) days after the Initial Closing Date, either a
Registration Statement on Form SB-2 or an amendment to an existing Registration
Statement, in either event registering for resale by the Investor a sufficient
number of shares of Common Stock for the Initial Investors to sell the
Registrable Securities (or such lesser number as may be required by the SEC, but
in no event less than two hundred percent (200%) of the aggregate number of
shares (A) into which the Initial Debentures and the Additional Debentures and
all interest thereon through their respective


                                       2
<PAGE>

Maturity Dates would be convertible at the time of filing of such Registration
Statement (assuming for such purposes that the Additional Debentures had been
issued at such date and that all Debentures had been eligible to be converted,
and had been converted, into Conversion Shares in accordance with their terms,
whether or not such issuance, accrual of interest, eligibility or conversion had
in fact occurred as of such date) and (B) which would be issued upon exercise of
all of the Warrants at the time of filing of the Registration Statement
(assuming for such purposes that the Warrants issued in connection with the
purchase and sale of all Debentures had been issued and that all Warrants had
been eligible to be exercised for the maximum number of shares contemplated
thereby and had been exercised in accordance with their terms, whether or not
such issuance, eligibility or exercise had in fact occurred as of such date).
The Registration Statement (W) shall include only the Registrable Securities and
the shares specifically listed on Exhibit 1 annexed hereto; and (X) shall also
state that, in accordance with Rule 416 and 457 under the Securities Act, it
also covers such indeterminate number of additional shares of Common Stock as
may become issuable upon conversion of the Debentures and the exercise of the
Warrants to prevent dilution resulting from stock splits, or stock dividends.
The Company will use its reasonable best efforts to cause such Registration
Statement to be declared effective on a date (the "Initial Required Effective
Date") which no later than is the earlier of (Y) five (5) days after notice by
the SEC that it may be declared effective or (Z) ninety (90) days after the
Initial Closing Date.
(Four)
(Five) (ii) If at any time (an "Increased Registered Shares Date"), the number
of shares of Common Stock represented by the Registrable Shares, issued or to be
issued as contemplated by the Transaction Agreements, exceeds the aggregate
number of shares of Common Stock then registered, the Company shall, within ten
(10) business days after receipt of a written notice from any Investor, either
(X) amend the Registration Statement filed by the Company pursuant to the
preceding provisions of this Section 2, if such Registration Statement has not
been declared effective by the SEC at that time, to register two hundred percent
(200%) of such Registrable Shares, computed as contemplated by the immediately
preceding subparagraph (i), or (Y) if such Registration Statement has been
declared effective by the SEC at that time, file with the SEC an additional
Registration Statement on Form SB-2 or other appropriate registration statement
form (an "Additional Registration Statement") to register two hundred percent
(200%) of the shares of Common Stock represented by the Registrable Shares,
computed as contemplated by the immediately preceding subparagraph (i), that
exceed the aggregate number of shares of Common Stock already registered. The
Company will use its reasonable best efforts to cause such Registration
Statement to be declared effective on a date (each, an "Increased Required
Effective Date") which is no later than (Q) with respect to a Registration
Statement under clause (X) of this subparagraph (ii), the Initial Required
Effective Date and (R) with respect to an Additional Registration Statement, the
earlier of (I) five (5) days after notice by the SEC that it may be declared
effective or (II) thirty (30) days after the Increased Registered Shares Date.
(Six)
(Seven) (iii) Except with respect to the party identified as the "Consultant" on
Exhibit 1 annexed hereto, it shall be a condition to the inclusion in the
Registration Statement of the shares specifically listed on Exhibit 1 annexed
hereto that the holder of such shares (each


                                       3
<PAGE>

such holder, an "Included Holder") agree in writing (an "Included Holder's
Agreement"), which writing shall be in favor of Buyer and enforceable against
such holder by Buyer (a copy of which Included Holder's Agreement shall be
provided to Buyer no later than the date the Registration Statement is first
filed with the SEC), that such Included Holder and any of such Included Holder's
transferees other than a Permitted Transferee (as defined below) (x) will not
sell or otherwise transfer, individually or on a combined basis, any shares
until thirty (30) days after the Effective Date, but thereafter may sell or
otherwise transfer an aggregate of the lesser of the number of shares specified
for such Included Holder on Exhibit 1 or 20,000 shares, and (y) after the
thirtieth day after the Effective Date, will not sell or otherwise transfer,
individually or on a combined basis, more than twenty percent (20%) of such
Included Holder's shares, if any, in excess of 20,000 shares listed in the
Registration Statement for such Included Holder (or transferee), during any
consecutive thirty (30) day period (the shares permitted to be transferred in
each such period are referred to as "Permitted Shares"). In addition to, and not
in lieu of the foregoing provisions of this subparagraph (iii), the Included
Holder's Agreement of any Included Holder who, as of the date of this Agreement,
holds a warrant to purchase Common Stock of the Company shall also provide that
such Included Holder agrees not to sell or otherwise transfer any of such
Included Holder's shares issued on exercise of such warrants prior to the date
which is thirty (30) days after the Effective Date, and that any sales and
transfers made thereafter will be made in compliance with the other terms and
conditions set forth in the Included Holder's Agreement. A "Permitted
Transferee" is a party acquiring all or a portion of the Permitted Shares in a
transaction made pursuant to the prospectus included in the Registration
Statement. The Buyer may require the Company to institute reasonable procedures
(such as, but not necessarily limited to, the establishment of an escrow
arrangement for the shares of each Included Holder) to assure compliance with
this provision.
(Eight)
(Nine) Payments by the Company.
(Ten)
(Eleven) (i) If the Registration Statement covering the Registrable Securities
is not filed in proper form with the SEC by the Required Filing Date, the
Company will make payment to the Initial Investor in such amounts and at such
times as shall be determined pursuant to this Section 2(b).
(Twelve)
(Thirteen) (ii) If the Registration Statement covering the Registrable
Securities is not effective by the relevant Required Effective Date or if the
Investor is restricted from making sales of Registrable Securities covered by a
previously effective Registration Statement at any time (the date such
restriction commences, a "Restricted Sale Date") after the Effective Date other
than during a Permitted Suspension Period (as defined below), then the Company
will make payments to the Initial Investor in such amounts and at such times as
shall be determined pursuant to this Section 2(b).
(Fourteen)
(Fifteen) (iii) The amount (the "Periodic Amount") to be paid by the Company to
the Initial Investor shall be determined as of each Computation Date (as defined
below) and such amount shall be equal to the Periodic Amount Percentage (as
defined below) of the Purchase Price for all Debentures for the period from the
date following the relevant


                                       4
<PAGE>

Required Filing Date, Required Effective Date or Restricted Sale Date, as the
case may be, to the first relevant Computation Date, and thereafter to each
subsequent Computation Date. The "Periodic Amount Percentage" means (A) two
percent (2%) of the Purchase Price for all the Debentures for the period from
the date following the relevant Required Filing Date, Required Effective Date or
Restricted Sale Date, as the case may be, to the first relevant Computation
Date, and (B) three percent (3%) of the Purchase Price of all Debentures to each
Computation Date thereafter. Anything in the preceding provisions of this
paragraph (iii) to the contrary notwithstanding, after the Effective Date the
Purchase Price shall be deemed to refer to the sum of (X) the principal amount
of all Debentures not yet converted and (Y) the Held Shares Value (as defined
below). The "Held Shares Value" means, for shares acquired by the Investor upon
a conversion within the thirty (30) days preceding the Restricted Sale Date, but
not yet sold by the Investor, the principal amount of the Debentures converted
into such Conversion Shares; provided, however, that if the Investor effected
more than one conversion during such thirty (30) day period and sold less than
all of such shares, the sold shares shall be deemed to be derived first from the
conversions in the sequence of such conversions (that is, for example, until the
number of shares from the first of such conversions have been sold, all shares
shall be deemed to be from the first conversion; thereafter, from the second
conversion until all such shares are sold). By way of illustration and not in
limitation of the foregoing, if the Registration Statement is timely filed but
is not declared effective until one hundred sixty-five (165) days after the
Initial Closing Date, the Periodic Amount will aggregate eight percent (8%) of
the Purchase Price of the Debentures (2% for days 91-120, plus 3% for days
121-150, plus 3% for days 151-165).
(Sixteen)
(Seventeen) (iv) Each Periodic Amount will be payable by the Company in cash or
other immediately available funds to the Investor monthly, without requiring
demand therefor by the Investor.
(Eighteen)
(Nineteen) (v) The parties acknowledge that the damages which may be incurred by
the Investor if the Registration Statement is not filed by the Required Filing
Date or if the Registration Statement has not been declared effective by a
Required Effective Date, including if the right to sell Registrable Securities
under a previously effective Registration Statement is suspended, may be
difficult to ascertain. The parties agree that the Periodic Amounts represent a
reasonable estimate on the part of the parties, as of the date of this
Agreement, of the amount of such damages.
(Twenty)
(Twenty-one) (vi) Notwithstanding the foregoing, the amounts payable by the
Company pursuant to this provision shall not be payable to the extent any delay
in the effectiveness of the Registration Statement occurs because of an act of,
or a failure to act or to act timely by the Initial Investor or its counsel, or
in the event all of the Registrable Securities may be sold pursuant to Rule 144
or another available exemption under the Act.
(Twenty-two)
(Twenty-three) (vii) "Computation Date" means (A) the date which is the earlier
of (1) thirty (30) days after the Required Filing Date, any relevant Required
Effective Date or a Restricted Sale Date, as the case may be, or (2) the date
after the Required Filing Date, such Required Effective Date or Restricted Sale
Date on which the Registration Statement is


                                       5
<PAGE>

filed (with respect to payments due as contemplated by Section 2(b)(i) hereof)
or is declared effective or has its restrictions removed (with respect to
payments due as contemplated by Section 2(b)(ii) hereof), as the case may be,
and (B) each date which is the earlier of (1) thirty (30) days after the
previous Computation Date or (2) the date after the previous Computation Date on
which the Registration Statement is filed (with respect to payments due as
contemplated by Section 2(b)(i) hereof) or is declared effective or has its
restrictions removed (with respect to payments due as contemplated by Section
2(b)(ii) hereof), as the case may be.
(Twenty-four)
(Twenty-five) (viii) Anything in the preceding provisions of this Section 2(b)
to the contrary notwithstanding, if, but only if, the Registration Statement is
declared effective within one hundred twenty (120) days following the Initial
Closing Date, the provisions of Section 2(b)(ii) shall not apply to the fact
that the Registration Statement was initially declared effective after the
Initial Required Effective Date, and the Company will not have any obligation to
pay any Periodic Amount to the Initial Investor with respect thereto; provided,
however, that the provisions of Section.2(b)(ii) shall continue to apply to all
other events described therein.
(Twenty-six)
17. Obligations of the Company. In connection with the registration of the
Registrable Securities, the Company shall do each of the following.
18.
(One) Prepare promptly, and file with the SEC by the Required Filing Date a
Registration Statement with respect to not less than the number of Registrable
Securities provided in Section 2(a) above, and thereafter use its reasonable
best efforts to cause such Registration Statement relating to Registrable
Securities to become effective by the Required Effective Date and keep the
Registration Statement effective at all times during the period (the
"Registration Period") continuing until the earliest of (i) the date that is two
(2) years after the last day of the calendar month following the month in which
the Effective Date occurs, (ii) the date when the Investors may sell all
Registrable Securities under Rule 144 or (iii) the date the Investors no longer
own any of the Registrable Securities, which Registration Statement (including
any amendments or supplements thereto and prospectuses contained therein) shall
not contain any untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances in which they were made, not misleading;
(Two)
(Three) (b) Prepare and file with the SEC such amendments (including
post-effective amendments) and supplements to the Registration Statement and the
prospectus used in connection with the Registration Statement as may be
necessary to keep the Registration Statement effective at all times during the
Registration Period, and, during the Registration Period, comply with the
provisions of the Securities Act with respect to the disposition of all
Registrable Securities of the Company covered by the Registration Statement
until such time as all of such Registrable Securities have been disposed of in
accordance with the intended methods of disposition by the seller or sellers
thereof as set forth in the Registration Statement;
(Four)


                                       6
<PAGE>

(Five) (c) The Company shall permit a single firm of counsel designated by the
Initial Investors to review the Registration Statement and all amendments and
supplements thereto a reasonable period of time (but not less than three (3)
business days) prior to their filing with the SEC, and not file any document in
a form to which such counsel reasonably objects.
(Six)
(Seven) (d) Notify each Investor, such Investor's legal counsel identified to
the Company (which, until further notice, shall be deemed to be Krieger &
Prager, ATTN: Samuel Krieger, Esq.; each, an "Investor's Counsel"), and any
managing underwriters immediately (and, in the case of (i)(A) below, not less
than five (5) days prior to such filing) and (if requested by any such Person)
confirm such notice in writing no later than one (1) business day following the
day (i)(A) when a Prospectus or any Prospectus supplement or post-effective
amendment to the Registration Statement is proposed to be filed; (B) whenever
the SEC notifies the Company whether there will be a "review" of such
Registration Statement; (C) whenever the Company receives (or a representative
of the Company receives on its behalf) any oral or written comments from the SEC
in respect of a Registration Statement (copies or, in the case of oral comments,
summaries of such comments shall be promptly furnished by the Company to the
Investors); and (D) with respect to the Registration Statement or any
post-effective amendment, when the same has become effective; (ii) of any
request by the SEC or any other Federal or state governmental authority for
amendments or supplements to the Registration Statement or Prospectus or for
additional information; (iii) of the issuance by the SEC of any stop order
suspending the effectiveness of the Registration Statement covering any or all
of the Registrable Securities or the initiation of any Proceedings for that
purpose; (iv) if at any time any of the representations or warranties of the
Company contained in any agreement (including any underwriting agreement)
contemplated hereby ceases to be true and correct in all material respects; (v)
of the receipt by the Company of any notification with respect to the suspension
of the qualification or exemption from qualification of any of the Registrable
Securities for sale in any jurisdiction, or the initiation or threatening of any
Proceeding for such purpose; and (vi) of the occurrence of any event that to the
best knowledge of the Company makes any statement made in the Registration
Statement or Prospectus or any document incorporated or deemed to be
incorporated therein by reference untrue in any material respect or that
requires any revisions to the Registration Statement, Prospectus or other
documents so that, in the case of the Registration Statement or the Prospectus,
as the case may be, it will not 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. In addition, the Company shall furnish the Investors with
copies of all intended written responses to the comments contemplated in clause
(C) of this Section 3(d) not later than one (1) business day in advance of the
filing of such responses with the SEC so that the Investors shall have the
opportunity to comment thereon.
(Eight)
(Nine) (e) Furnish to each Investor and such Investor's Counsel (i) promptly
after the same is prepared and publicly distributed, filed with the SEC, or
received by the Company, one (1) copy of the Registration Statement, each
preliminary prospectus and prospectus, and each amendment or supplement thereto,
and (ii) such number of copies of a prospectus, and all amendments and
supplements thereto and such other documents, as such Investor


                                       7
<PAGE>
may reasonably request in order to facilitate the disposition of the Registrable
Securities owned by such Investor;
(Ten)
(Eleven) (f) As promptly as practicable after becoming aware thereof, notify
each Investor of the happening of any event of which the Company has knowledge,
as a result of which the prospectus included in the Registration Statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a 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, and use its best efforts promptly to prepare a supplement or
amendment to the Registration Statement or other appropriate filing with the SEC
to correct such untrue statement or omission, and deliver a number of copies of
such supplement or amendment to each Investor as such Investor may reasonably
request;
(Twelve)
(Thirteen) (g) As promptly as practicable after becoming aware thereof, notify
each Investor who holds Registrable Securities being sold (or, in the event of
an underwritten offering, the managing underwriters) of the issuance by the SEC
of a Notice of Effectiveness or any notice of effectiveness or any stop order or
other suspension of the effectiveness of the Registration Statement at the
earliest possible time;
(Fourteen)
(Fifteen) (h) Notwithstanding the foregoing, if at any time or from time to time
after the date of effectiveness of the Registration Statement, the Company
notifies the Investors in writing of the existence of a Potential Material
Event, the Investors shall not offer or sell any Registrable Securities, or
engage in any other transaction involving or relating to the Registrable
Securities, from the time of the giving of notice with respect to a Potential
Material Event until such Investor receives written notice from the Company that
such Potential Material Event either has been disclosed to the public or no
longer constitutes a Potential Material Event; provided, however, that the
Company may not so suspend the right to such holders of Registrable Securities
during the periods the Registration Statement is required to be in effect other
than during a Permitted Suspension Period. The term "Permitted Suspension
Period" means one or more suspension periods during any consecutive 12-month
period which suspension periods, in the aggregate, do not exceed fifty (50)
days, provided, however, that no one such suspension period shall either (i) be
for more than twenty (20) days or (ii) begin less than ten (10) business days
after the last day of the preceding suspension (whether or not such last day was
during or after a Permitted Suspension Period).
(Sixteen)
(Seventeen) (i) Use its reasonable efforts to secure and maintain the
designation of all the Registrable Securities covered by the Registration
Statement on the "OTC Bulletin Board Market" of the National Association of
Securities Dealers Automated Quotations System ("NASDAQ") within the meaning of
Rule 11Aa2-1 of the SEC under the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), and the quotation of the Registrable Securities on The
NASDAQ Bulletin Board Market; and, without limiting the generality of the
foregoing, to arrange for at least two market makers to register with the
National Association of Securities Dealers, Inc. ("NASD") as such with respect
to such Registrable Securities;
(Eighteen)


                                       8
<PAGE>

(Nineteen) (j) Provide a transfer agent and registrar, which may be a single
entity, for the Registrable Securities not later than the effective date of the
Registration Statement;
(Twenty)
(Twenty-one) (k) Cooperate with the Investors to facilitate the timely
preparation and delivery of certificates for the Registrable Securities to be
offered pursuant to the Registration Statement and enable such certificates for
the Registrable Securities to be in such denominations or amounts as the case
may be, as the Investors may reasonably request, and, within three (3) business
days after a Registration Statement which includes Registrable Securities is
ordered effective by the SEC, the Company shall deliver, and shall cause legal
counsel selected by the Company to deliver, to the transfer agent for the
Registrable Securities (with copies to the Investors whose Registrable
Securities are included in such Registration Statement) an appropriate
instruction and opinion of such counsel; and
(Twenty-two)
(Twenty-three) (l) Take all other reasonable actions necessary to expedite and
facilitate disposition by the Investor of the Registrable Securities pursuant to
the Registration Statement.
(Twenty-four)
19. Obligations of the Investors. In connection with the registration of the
Registrable Securities, the Investors shall have the following obligations:
20.
(One) It shall be a condition precedent to the obligations of the Company to
complete the registration pursuant to this Agreement with respect to the
Registrable Securities of a particular Investor that such Investor shall furnish
to the Company such information regarding itself, the Registrable Securities
held by it, and the intended method of disposition of the Registrable Securities
held by it, as shall be reasonably required to effect the registration of such
Registrable Securities and shall execute such documents in connection with such
registration as the Company may reasonably request. At least ten (10) days prior
to the first anticipated filing date of the Registration Statement, the Company
shall notify each Investor of the information the Company requires from each
such Investor (the "Requested Information") if such Investor elects to have any
of such Investor's Registrable Securities included in the Registration
Statement. If at least two (2) business days prior to the filing date the
Company has not received the Requested Information from an Investor (a
"Non-Responsive Investor"), then the Company may file the Registration Statement
without including Registrable Securities of such Non-Responsive Investor;
(Two)
(Three) Each Investor, by such Investor's acceptance of the Registrable
Securities, agrees to cooperate with the Company as reasonably requested by the
Company in connection with the preparation and filing of the Registration
Statement hereunder, unless such Investor has notified the Company in writing of
such Investor's election to exclude all of such Investor's Registrable
Securities from the Registration Statement; and
(Four)
(Five) Each Investor agrees that, upon receipt of any notice from the Company of
the happening of any event of the kind described in Section 3(e) or 3(f), above,
such Investor will

                                       9
<PAGE>

immediately discontinue disposition of Registrable Securities pursuant to the
Registration Statement covering such Registrable Securities until such
Investor's receipt of the copies of the supplemented or amended prospectus
contemplated by Section 3(e) or 3(f) and, if so directed by the Company, such
Investor shall deliver to the Company (at the expense of the Company) or destroy
(and deliver to the Company a certificate of destruction) all copies in such
Investor's possession, of the prospectus covering such Registrable Securities
current at the time of receipt of such notice. (Six)
21. Expenses of Registration. (a) All reasonable expenses (other than
underwriting discounts and commissions of the Investor) incurred in connection
with registrations, filings or qualifications pursuant to Section 3, but
including, without limitation, all registration, listing, and qualifications
fees, printers and accounting fees, the fees and disbursements of counsel for
the Company and a fee for a single counsel for the Investors not exceeding, in
the aggregate for all Investors, $3,500, shall be borne by the Company.
22.
23. (b) Except as and to the extent specifically set forth in Exhibit 1 attached
hereto, neither the Company nor any of its subsidiaries has, as of the date
hereof, nor shall the Company nor any of its subsidiaries, on or after the date
of this Agreement, enter into any agreement with respect to its securities that
is inconsistent with the rights granted to the Investors in this Agreement or
otherwise conflicts with the provisions hereof. Except as and to the extent
specifically set forth in Exhibit 1 attached hereto, neither the Company nor any
of its subsidiaries has previously entered into any agreement granting any
registration rights with respect to any of its securities to any Person. Without
limiting the generality of the foregoing, without the written consent of the
Investors holding a majority of the Registrable Securities, the Company shall
not grant to any person the right to request the Company to register any
securities of the Company under the Securities Act unless the rights so granted
are subject in all respects to the prior rights in full of the Investors set
forth herein, and are not otherwise in conflict or inconsistent with the
provisions of this Agreement and the other Transaction Agreements.
24.
25. Indemnification. In the event any Registrable Securities are included in a
Registration Statement under this Agreement:
26.
(One) To the extent permitted by law, the Company will indemnify and hold
harmless each Investor who holds such Registrable Securities, the directors, if
any, of such Investor, the officers, if any, of such Investor, each person, if
any, who controls any Investor within the meaning of the Securities Act or the
Exchange Act (each, an "Indemnified Person" or "Indemnified Party"), against any
losses, claims, damages, liabilities or expenses (joint or several) incurred
(collectively, "Claims") to which any of them may become subject under the
Securities Act, the Exchange Act or otherwise, insofar as such Claims (or
actions or proceedings, whether commenced or threatened, in respect thereof)
arise out of or are based upon any of the following statements, omissions or
violations in the Registration Statement, or any post-effective amendment
thereof, or any prospectus included therein: (i) any untrue statement or alleged
untrue statement of a material fact contained in the Registration Statement or
any post-effective amendment thereof or the omission or alleged omission to
state therein a material fact required to

                                       10
<PAGE>

be stated therein or necessary to make the statements therein not misleading,
(ii) any untrue statement or alleged untrue statement of a material fact
contained in the final prospectus (as amended or supplemented, if the Company
files any amendment thereof or supplement thereto with the SEC) or the omission
or alleged omission to state therein any material fact necessary to make the
statements made therein, in light of the circumstances under which the
statements therein were made, not misleading or (iii) any violation or alleged
violation by the Company of the Securities Act, the Exchange Act, any state
securities law or any rule or regulation under the Securities Act, the Exchange
Act or any state securities law (the matters in the foregoing clauses (i)
through (iii) being, collectively, "Violations"). Subject to clause (b) of this
Section 6, the Company shall reimburse the Investors, promptly as such expenses
are incurred and are due and payable, for any legal fees or other reasonable
expenses incurred by them in connection with investigating or defending any such
Claim. Notwithstanding anything to the contrary contained herein, the
indemnification agreement contained in this Section 6(a) shall not (I) apply to
a Claim arising out of or based upon a Violation which occurs in reliance upon
and in conformity with information furnished in writing to the Company by or on
behalf of any Indemnified Person expressly for use in connection with the
preparation of the Registration Statement or any such amendment thereof or
supplement thereto, if such prospectus was timely made available by the Company
pursuant to Section 3(c) hereof; (II) be available to the extent such Claim is
based on a failure of the Investor to deliver or cause to be delivered the
prospectus made available by the Company; or (III) apply to amounts paid in
settlement of any Claim if such settlement is effected without the prior written
consent of the Company, which consent shall not be unreasonably withheld. Each
Investor will indemnify the Company and its officers, directors and agents
(each, an "Indemnified Person" or "Indemnified Party") against any claims
arising out of or based upon a Violation which occurs in reliance upon and in
conformity with information furnished in writing to the Company, by or on behalf
of such Investor, expressly for use in connection with the preparation of the
Registration Statement, subject to such limitations and conditions as are
applicable to the Indemnification provided by the Company to this Section 6.
Such indemnity shall remain in full force and effect regardless of any
investigation made by or on behalf of the Indemnified Person and shall survive
the transfer of the Registrable Securities by the Investors pursuant to Section
9.
(Two)
(Three) Promptly after receipt by an Indemnified Person or Indemnified Party
under this Section 6 of notice of the commencement of any action (including any
governmental action), such Indemnified Person or Indemnified Party shall, if a
Claim in respect thereof is to be made against any indemnifying party under this
Section 6, deliver to the indemnifying party a written notice of the
commencement thereof and the indemnifying party shall have the right to
participate in, and, to the extent the indemnifying party so desires, jointly
with any other indemnifying party similarly noticed, to assume control of the
defense thereof with counsel mutually satisfactory to the indemnifying party and
the Indemnified Person or the Indemnified Party, as the case may be. In case any
such action is brought against any Indemnified Person or Indemnified Party, and
it notifies the indemnifying party of the commencement thereof, the indemnifying
party will be entitled to participate in, and, to the extent that it may wish,
jointly with any other indemnifying party similarly notified, assume the defense
thereof, subject to the provisions herein stated and after notice from the
indemnifying party to such Indemnified Person


                                       11
<PAGE>

or Indemnified Party of its election so to assume the defense thereof, the
indemnifying party will not be liable to such Indemnified Person or Indemnified
Party under this Section 6 for any legal or other reasonable out-of-pocket
expenses subsequently incurred by such Indemnified Person or Indemnified Party
in connection with the defense thereof other than reasonable costs of
investigation, unless the indemnifying party shall not pursue the action of its
final conclusion. The Indemnified Person or Indemnified Party shall have the
right to employ separate counsel in any such action and to participate in the
defense thereof, but the fees and reasonable out-of-pocket expenses of such
counsel shall not be at the expense of the indemnifying party if the
indemnifying party has assumed the defense of the action with counsel reasonably
satisfactory to the Indemnified Person or Indemnified Party. The failure to
deliver written notice to the indemnifying party within a reasonable time of the
commencement of any such action shall not relieve such indemnifying party of any
liability to the Indemnified Person or Indemnified Party under this Section 6,
except to the extent that the indemnifying party is prejudiced in its ability to
defend such action. The indemnification required by this Section 6 shall be made
by periodic payments of the amount thereof during the course of the
investigation or defense, as such expense, loss, damage or liability is incurred
and is due and payable.
(Four)
27. Contribution. To the extent any indemnification by an indemnifying party is
prohibited or limited by law, the indemnifying party agrees to make the maximum
contribution with respect to any amounts for which it would otherwise be liable
under Section 6 to the fullest extent permitted by law; provided, however, that
(a) no contribution shall be made under circumstances where the maker would not
have been liable for indemnification under the fault standards set forth in
Section 6; (b) no seller of Registrable Securities guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any seller of Registrable Securities who
was not guilty of such fraudulent misrepresentation; and (c) contribution by any
seller of Registrable Securities shall be limited in amount to the net amount of
proceeds received by such seller from the sale of such Registrable Securities.
28.
29. Reports under Exchange Act. With a view to making available to the Investors
the benefits of Rule 144 promulgated under the Securities Act or any other
similar rule or regulation of the SEC that may at any time permit the Investors
to sell securities of the Company to the public without registration ("Rule
144"), the Company agrees to:
30.
(One) make and keep public information available, as those terms are understood
and defined in Rule 144;
(Two)
(Three) file with the SEC in a timely manner all reports and other documents
required of the Company under the Securities Act and the Exchange Act; and
(Four)
(Five) furnish to each Investor so long as such Investor owns Registrable
Securities, promptly upon request, (i) a written statement by the Company that
it has complied with the reporting requirements of Rule 144, the Securities Act
and the Exchange Act, (ii) a copy of the

                                       12
<PAGE>

most recent annual or quarterly report of the Company and such other reports and
documents so filed by the Company and (iii) such other information as may be
reasonably requested to permit the Investors to sell such securities pursuant to
Rule 144 without registration.
(Six)
31. Assignment of the Registration Rights. The rights to have the Company
register Registrable Securities pursuant to this Agreement shall be
automatically assigned by the Investors to any transferee of the Registrable
Securities (or all or any portion of any unconverted Debenture or unexercised
Warrant) only if: (a) the Investor agrees in writing with the transferee or
assignee to assign such rights, and a copy of such agreement is furnished to the
Company within a reasonable time after such assignment, (b) the Company is,
within a reasonable time after such transfer or assignment, furnished with
written notice of (i) the name and address of such transferee or assignee and
(ii) the securities with respect to which such registration rights are being
transferred or assigned, (c) immediately following such transfer or assignment
the further disposition of such securities by the transferee or assignee is
restricted under the Securities Act and applicable state securities laws, and
(d) at or before the time the Company received the written notice contemplated
by clause (b) of this sentence the transferee or assignee agrees in writing with
the Company to be bound by all of the provisions contained herein. In the event
of any delay in filing or effectiveness of the Registration Statement as a
result of such assignment, the Company shall not be liable for any damages
arising from such delay, or the payments set forth in Section 2(c) hereof
arising from such delay. 32.
33. Amendment of Registration Rights. Any provision of this Agreement may be
amended and the observance thereof may be waived (either generally or in a
particular instance and either retroactively or prospectively), only with the
written consent of the Company and Investors who hold an sixty-seven (67%)
percent interest of the Registrable Securities. Any amendment or waiver effected
in accordance with this Section 10 shall be binding upon each Investor and the
Company.
34.
35. 11. Miscellaneous.
36.
37. (a) A person or entity is deemed to be a holder of Registrable Securities
whenever such person or entity owns of record such Registrable Securities. If
the Company receives conflicting instructions, notices or elections from two or
more persons or entities with respect to the same Registrable Securities, the
Company shall act upon the basis of instructions, notice or election received
from the registered owner of such Registrable Securities.
38.
39. (b) Notices required or permitted to be given hereunder shall be given in
the manner contemplated by the Agreement, (i) if to the Company or to the
Initial Investor, to their respective address contemplated by the Agreement, and
(iii) if to any other Investor, at such address as such Investor shall have
provided in writing to the Company, or at such other address as each such party
furnishes by notice given in accordance with this Section 11(b).
40.


                                       13
<PAGE>

41. (c) Failure of any party to exercise any right or remedy under this
Agreement or otherwise, or delay by a party in exercising such right or remedy,
shall not operate as a waiver thereof.
42.
43. (d) This Agreement shall be governed by and interpreted in accordance with
the laws of the State of Delaware for contracts to be wholly performed in such
state and without giving effect to the principles thereof regarding the conflict
of laws. Each of the parties consents to the jurisdiction of the federal courts
whose districts encompass any part of the City of Wilmington or the state courts
of the State of Delaware sitting in the City of Wilmington in connection with
any dispute arising under this Agreement and hereby waives, to the maximum
extent permitted by law, any objection, including any objection based on forum
non coveniens, to the bringing of any such proceeding in such jurisdictions. To
the extent determined by such court, the Company shall reimburse the Buyer for
any reasonable legal fees and disbursements incurred by the Buyer in enforcement
of or protection of any of its rights under this Agreement.
44.
45. (e) If any provision of this Agreement shall be invalid or unenforceable in
any jurisdiction, such invalidity or unenforceability shall not affect the
validity or enforceability of the remainder of this Agreement or the validity or
enforceability of this Agreement in any other jurisdiction.
46.
47. (f) Subject to the requirements of Section 9 hereof, this Agreement shall
inure to the benefit of and be binding upon the successors and assigns of each
of the parties hereto.
48.
49. (g) All pronouns and any variations thereof refer to the masculine, feminine
or neuter, singular or plural, as the context may require.
50.
51. (h) The headings in this Agreement are for convenience of reference only and
shall not limit or otherwise affect the meaning thereof.
52.
53. (i) This Agreement may be executed in one or more counterparts, each of
which shall be deemed an original but all of which shall constitute one and the
same agreement. This Agreement, once executed by a party, may be delivered to
the other party hereto by telephone line facsimile transmission of a copy of
this Agreement bearing the signature of the party so delivering this Agreement.
54.
55. (j) The Company acknowledges that any failure by the Company to perform its
obligations under Section 3(a) hereof, or any delay in such performance could
result in loss to the Investors, and the Company agrees that, in addition to any
other liability the Company may have by reason of such failure or delay, the
Company shall be liable for all direct damages caused by any such failure or
delay, unless the same is the result of force majeure. Neither party shall be
liable for consequential damages.
56.
