                               PROSPECTUS SUMMARY

      This summary highlights certain information contained elsewhere in this
prospectus. You should read the entire prospectus carefully, especially the
risks of investing in our common stock discussed under "Risk Factors." Except as
otherwise noted, the information in this prospectus does not give effect to the
conversion of outstanding convertible securities or to the exercise of
outstanding options and warrants. Unless otherwise noted, references in this
prospectus to "TTR," "we," "our" and "us" refer to TTR Technologies, Inc., a
Delaware corporation, and our wholly owned subsidiary, TTR Technologies, Ltd.,
an Israeli company.

      We design and develop anti-piracy software technologies that provide copy
protection for electronic content distributed on optical media and over the
Internet. Our proprietary anti-piracy technology, MusicGuard(TM), is a unique
hardware-based technology designed to prevent the unauthorized copying of audio
content distributed on CDs. Our copy protection technologies are designed to be
transparent to the legitimate end-user.

      As of November 24, 1999, we entered into an agreement with Macrovision
Corporation to jointly design and develop and market a copy protection product
designed to thwart the illegal copying of audio content on CDs, DVDs and other
optical media. The new product will be based primarily upon our MusicGuard
technology as well as related Macrovision technology and will be jointly owned
by us and Macrovision. We expect that the immediate application of the
technology we are developing with Macrovision will be of interest for the music
distribution business and recording studios whose products are customarily
distributed on CDs. We granted to Macrovision an exclusive world-wide royalty
bearing license to design, develop and market the copy protection technology
which we are jointly developing.

      Our immediate goal is to establish the proposed audio content protection
technology which we and Macrovision are developing as the leading product in the
target market of audio content copy protection for the high-volume recording
industry. Additionally, we are actively developing other technologies and
looking to acquire technologies which are synergistic with our current business
and will enable us to leverage our knowledge base and skill.

      We were organized in July 1994. We have an Israeli subsidiary, organized
in December 1994, through which we conduct research and development. Our
principal executive offices are located at 2 HaNager Street, Kfar Saba, Israel,
telephone 011-972-9-766-2393. We also have a mailing address at 67 Wall Street,
Suite 2411, New York, New York 10005 and can be reached by telephone in New York
at 212-323-8284. Our Web site is www.ttrtech.com. Information contained on our
Web site is not, and should not be deemed to be, a part of this prospectus.

                                  RISK FACTORS

      This offering involves a high degree of risk. You should be able to bear a
complete loss of your investment. You should carefully consider the risks
described below and the other information in this prospectus before deciding to
invest in shares of our common stock. If any of the following risks actually
occur, our business, financial condition and results of operations would likely
suffer. In such case, the market price of our common stock could decline, and
you may lose all or a part of the money you pay to buy our common stock.

      Our relationship with Macrovision is very important to us, since it will
be the exclusive licensee of our anti-piracy products and it is responsible for
marketing them.

      As of November 24, 1999, we entered into a ten year agreement with
Macrovision to jointly develop a commercially viable anti-piracy protection
technology and product for audio content distribution on optical media. We
granted to Macrovision exclusive worldwide royalty bearing rights to our
proprietary anti-piracy technology, MusicGuard, which serves as the primary
basis for the proposed audio content protection technology. Under the terms of
our agreement, Macrovision is responsible for promoting and marketing the
proposed music protection technology or product. Macrovision has the discretion
to determine the staffing and resources it allocates to commercialize the
technology consistent with Macrovision's good faith determination as to the
technology's commercial potential. We also granted to Macrovision exclusive
rights to our proprietary CD software anti-piracy protection technology,
DiscGuard, which is the only commercially available product we currently have.
Only a limited portion of the license for DiscGuard is royalty bearing and
Macrovision is not required to pay any minimum royalties in order to retain its
exclusivity. We


                                       2
<PAGE>

expect that sales through Macrovision will account for most of our revenues for
at least the next two years. We believe that the rapid penetration of the
proposed music protection technologies in the recording industry in the United
States and Europe to be crucial to our success. If we are unable to effectively
manage and maintain our relationship with Macrovision or for any reason
Macrovision cannot successfully market MusicGuard, our business will be
materially adversely affected. In addition, our condition could be adversely
affected by changes in the financial condition of Macrovision or by any other
changes to Macrovision's business.

      We do not currently have any commercially viable products or technologies
and we cannot assure you that we will develop any.

      MusicGuard, our proprietary anti-piracy protection technology for audio
content distributed on CDs, is not currently commercially viable but will serve
as the primary basis for the proposed music protection technology that we and
Macrovision are jointly designing and developing. Under the terms of our
agreement with Macrovision, we will work jointly with Macrovision to complete a
product suitable for commercial launch. We estimate that this project will take
nine months, six months until the commercial launch and three months following
the commercial launch. We have also given to Macrovision an exclusive worldwide
partially royalty bearing license to DiscGuard, which we launched commercially
in February, 1998. We expect that Macrovision will use components of DiscGuard
to support its CD-ROM product, SafeDisc(TM). Although we are working to develop
technologies with applications in other areas, these technologies are at an
early stage. Currently, we have no other commercially viable product or
technology.

      Even if we develop other commercially viable technologies, the right of
first refusal we have granted to Macrovision with respect to certain products
may impair our ability to exploit them.

      Under the terms of our agreement with Macrovision, we have granted to
Macrovision first refusal rights until December 31, 2009 with respect to any
music protection technology we develop which is not included in the license to
Macrovision and any Internet digital rights management technologies we develop
which are applicable to music, music video, video, software or data publishing
products or markets. These rights include rights of ownership if we decide to
sell the technology or worldwide exclusive marketing or distribution rights if
we decide to license the technology. Our obligation is to negotiate a sale or
license to Macrovision in good faith should we receive a bona fide offer from a
third party to purchase or license the technology and should Macrovision notify
us of its interest in acquiring the technology. As is ordinarily the case where
a right of first refusal is granted, the existence of this right may impair our
ability to fully exploit the commercial potential inherent in other technology
we may develop which is subject to this right by creating the possibility that
an interested third party may abstain from making an offer for our technology
due to a possible concern on the part of such third party that its offer will be
utilized by us solely for negotiating an offer from Macrovision on more
favorable terms.

      We have lost money in every quarter and year, and we expect these losses
to continue in the foreseeable future.

      Since we began our operations in 1994, we have lost money in every quarter
and year. As of December 31, 1999, we had an accumulated deficit of
approximately $24.8 million. If our revenue does not increase and we cannot
adjust our level of spending adequately, we may not generate sufficient revenue
to become profitable. Even if we do become profitable, we may not be able to


                                       3
<PAGE>

sustain or increase profitability on a quarterly or annual basis in the future.
Our ability to generate revenue depends primarily upon our ability to jointly
develop with Macrovision the audio content copy protection technology to the
point it becomes commercially viable and Macrovision's success in promoting and
marketing the technology.

      We have only been in business for a short period of time, so your basis
for evaluating us is limited.

      We are a development stage company with a limited history of operations.
Prior to the commencement of our joint efforts with Macrovision to develop a
commercially viable audio content protection product and before our software
product, DiscGuard, first became commercially available in February 1998, we
were engaged primarily in research and development. As a result, there is a
limited history of operations for evaluating our business. You must consider the
risks and difficulties frequently encountered by early stage companies in new
and rapidly evolving markets, including the audio content copy protection and
anti-piracy market. Some of these risks and uncertainties relate to our ability
to:

o     complete, together with Macrovision, the design and development of audio
      content protection technology of a commercially viable product or
      technology;

o     stay ahead of the efforts of hackers and counterfeiters to circumvent our
      copy protection technologies;

o     respond effectively to actions taken by our competitors;

o     build our organizational and technical infrastructures to manage our
      growth effectively;

o     design, develop and implement effective products for existing clients and
      new clients;

o     extend MusicGuard protection to DVDs; and

o     attract, retain and motivate qualified personnel.

      If we are unsuccessful in addressing these risks and uncertainties, our
business, financial condition and results of operations will be materially and
adversely affected.

      The market for audio content copy protection technology is unproven.

      The market for copy protection technology for audio content distribution
on CDs, especially in the consumer multi-media market, is unproven. For us to be
successful in entering this market, recording studios and artists must accept
copy protection generally and also adopt the solution that we are developing
with Macovision. There can be no assurance that copy protection of multi-media
audio content distributed on CDs will be widely commercially accepted. For
example, consumers may react negatively to the introduction of copy protected
CDs if they are prevented from copying the content of their favorite audio
content. Moreover, copy protection may not be effective or compatible with all
hardware platforms or configurations or may prove to be easily circumvented.
Further, the technology we are developing with Macrovision may not achieve or
sustain market acceptance under emerging industry standards. If the market for
copy protection of audio content distributed on CDs fails to develop or develops
more slowly than expected, or if MusicGuard does


                                       4
<PAGE>

not achieve or sustain market acceptance, our business, financial condition and
results of operations would be materially adversely affected.

      You should not rely on our quarterly operating results as an indication of
how we will do in the future.

      Our quarterly operating results may vary significantly in the foreseeable
future due to a number of factors that could affect our revenue, expenses or
prospects during any particular quarter. These factors include:

o     the success of Macrovision in promoting and marketing any music protection
      technology developed through our joint efforts.

o     the demand for audio content anti-piracy protection in general and for CDs
      in particular, and, potentially, for DVDs;

o     the degree of acceptance of our copy protection technologies by recording
      studios and artists;

o     changes in our operating expenses;

o     changes in fees paid for copy protection of audio content distributed on
      CDs resulting from competition or other factors;

o     economic conditions specific to the recording industry;

o     anticipated seasonality of revenues relating to sales of music CDs to
      consumers in our target market.

      In any given quarter, we may expend substantial funds and management
resources and yet not obtain adequate revenue, and we may not be able to adjust
spending in a timely manner to compensate for any unexpected shortfall in our
revenue. Any significant shortfall could have an immediate material and adverse
effect on our business, financial condition and results of operations.

      Due to all of the foregoing factors, and the other risks discussed in this
section, you should not rely on quarter-to-quarter comparisons of our results of
operations as an indication of future performance. It is possible that in some
future periods our operating results will be below the expectations of public
market analysts and investors. In this event, the price of our common stock
would likely fall.

      For at least the next two years, we expect to derive most of our net
revenues and operating income from royalties collected from Macrovision in
respect of sales of copy protection technology or products. We cannot assure you
that we will receive any revenues from these royalties or if revenues are
received, that they will grow significantly or at all. Any growth in revenues
from these fees will depend on the use of our copy protection technology by a
larger number of recording studios and artists. In order to increase our market
penetration, we must persuade recording studios and artists that the cost of
licensing our technology is outweighed by the increase in revenues from
additional sales of the copy protected material that the recording studios and
artists would achieve as a result of using copy protection.


                                       5
<PAGE>

      There are many competitors in the copy protection industry and we may not
be able to compete effectively against them.

      There is currently no commercially available technology which prevents the
faithful copying of compact discs. There can be no assurance that companies with
substantially greater financial, technological, marketing, personnel and
research development resources than ours will not develop and begin marketing a
similar technology. While no technology is currently available, the Secure
Digital Music Initiative is a forum of companies who have agreed to develop a
standard for copy protection of digital music. The standard developed and being
improved upon by the Initiative will apply to next generation portable playback
devices. There can be no assurance that if and when the standard is implemented,
the MusicGuard technology will be able to effectively compete against copy
protection technologies based on the Initiative's standard.

Third parties may be able to circumvent our anti-piracy technology.

      We must continually enhance and upgrade audio content protection
technology to stay ahead of the efforts of counterfeiters and hackers to
circumvent our technologies, even in the face of the new United States Digital
Millennium Copyright Act. The Act outlaws copy protection circumvention devices
and technologies beginning in May 2000 and currently provides for both criminal
and civil penalties for companies or individuals who import, produce or
distribute devices designed to circumvent copy protection devices and
technologies. It is conceivable that counterfeiters and hackers could develop a
way to circumvent our copy protection techniques, which may result in a
potentially substantial decrease in the demand for our products. Additionally,
music rights owners could choose not to use our anti-piracy technology if they
believe that our technology will be unable to deter counterfeiters or if they
believe it interferes with legitimate consumer use of the original copyrighted
product. In this regard, the copy protection technologies are intended to
prevent both consumer copying and professional remastering and replication. Any
reduction in demand for our products could have a material adverse effect on our
business, financial condition and results of operations.

We are vulnerable to technological obsolescence.

      The proposed audio protection technology is based upon a single set of
core technologies. The market for this technology and products is characterized
by rapid change, often resulting in product obsolescence or short product life
cycles. Although we are not aware of any developments in the audio content
protection industry which would render our planned products less competitive or
obsolete, there can be no assurance that future technological changes or the
development of new or competitive products by others will not do so.

      We have very few employees and are particularly dependent on our Chief
Technology Officer.

      We have a small number of employees. Although we believe we maintain a
core group sufficient for us to effectively conduct our operations, the loss of
certain of our key personnel could, to varying degrees, have an adverse effect
on our operations and product development. The loss of Dr. Baruch Sollish, our
Chief Technology Officer, would have a material adverse affect. We have not
obtained "key-man" life insurance on the life of Dr. Sollish. Our key employees
and corporate officers all reside in Israel.


                                       6

      We are subject to risks associated with international operations.

      We conduct business from our facilities in Israel and the United States,
and through our exclusive licensee, Macrovision. Our international operations
and activities subject us to a number of risks, including the risk of political
and economic instability, difficulty in managing foreign operations, potentially
adverse taxes, higher expenses and difficulty in collection of accounts
receivable. In addition, although we receive most of our revenue in U.S.
dollars, a substantial portion of our payroll and other expenses are paid in the
currency of Israel, where most of our employees reside and our research and
development operations are located. Because our financial results are reported
in U.S. dollars, they are affected by changes in the value of the various
foreign currencies that we use to make payments in relation to the U.S. dollar.
We do not currently cover known or anticipated operating exposures through
foreign currency exchange option or forward contracts.

      We are subject to risks associated with operations in Israel.

      Our Israeli subsidiary maintains offices and research and development
facilities in Israel and is directly affected by prevailing economic, military
and political conditions that affect Israel.

      We need to establish and maintain licensing relationships with companies
in related fields.

      Our success in developing and commercializing other technologies will
depend in part upon our ability to establish and maintain licensing
relationships with companies in related business fields, including international
distributors. We believe that these relationships can allow us greater access to
manufacturing, sales and distribution resources. However, the amount and timing
of resources to be devoted to these activities by these other companies may not
be within our control. We may not be able to maintain relationships or enter
into beneficial relationships in the future. Other parties may not perform their
obligations as expected. Our reliance on others for the development,
manufacturing and distribution of our technologies and products may result in
unforeseen problems. There can be no assurance that our licensees will not
develop or pursue alternative technologies either on their own or in
collaboration with others, including our competitors, as a means of developing
or marketing products targeted by the collaborative programs and by our
products.

Our efforts to protect our intellectual property rights may not be adequate.

      Our success depends on our proprietary technologies. We rely on a
combination of patent, trademark, copyright and trade secret laws, nondisclosure
and other contractual provisions, and technical measures to protect our
intellectual property rights. Our patents, trademarks or copyrights may be
challenged and invalidated or circumvented. Any patents that issue from our
pending or future patent applications or the claims in pending patent
applications may not be of sufficient scope or strength or be issued in all
countries where our products can be sold or our technologies can be licensed to
provide meaningful protection or any commercial advantage to us. Others may
develop technologies that are similar or superior to our technologies, duplicate
our technologies or design around our patents. Effective intellectual property
protection may be unavailable or limited in certain foreign countries. Despite
efforts to protect our proprietary rights, unauthorized parties may attempt to
copy or otherwise use aspects of processes and devices that we regard as
proprietary. Policing unauthorized use of our proprietary information is
difficult, and there can be no assurance that the steps we have taken will
prevent misappropriation of our technologies. In the event that our intellectual
property protection is insufficient to protect our intellectual property rights,
we could


                                       7
<PAGE>

face increased competition in the market for our products and technologies,
which could have a material adverse effect on our business, financial condition
and results of operations.

      Litigation may be necessary in the future to enforce any patents that may
issue and other intellectual property rights, to protect our trade secrets or to
determine the validity and scope of the proprietary rights of others. There can
be no assurance that any litigation of these types will be successful.
Litigation could result in substantial costs, including indemnification of
customers, and diversion of resources and could have a material adverse effect
on our business, financial condition and results of operations, whether or not
this litigation is determined adversely to us. In the event of an adverse ruling
in any litigation, we might be required to pay substantial damages, discontinue
the use and sale of infringing products, expend significant resources to develop
non-infringing technology or obtain licenses to infringed technology. Our
failure to develop or license a substitute technology could have a material
adverse effect on our business, financial condition and results of operations.

      The rights of first refusal we have granted to Macrovision relating to the
sale of our equity securities may impair our ability to obtain other financing.

      In the January 12, 2000 stock purchase agreement under which we sold to
Macrovision $4 million of our common stock, we granted to Macrovision rights of
first refusal to purchase equity securities (including securities convertible or
exchangeable into common stock) we propose to sell to third parties if the
amount of the securities to be sold would constitute a majority of our
outstanding common stock. Subject to some exceptions, we further granted to
Macrovision a right to purchase its pro rata share (based on Macrovision's then
current ownership of common stock) of any equity securities we offer in private
transactions above a certain amount. The existence of these rights may impair
our ability to obtain equity financing from third parties on terms satisfactory
to us or at all because investors may be reluctant to devote the time and
expense necessary to negotiate the terms of a transaction which we may not be
able to consummate with them if Macrovision elects to exercise its rights.
However, Macrovision waived its right of first refusal with respect to our
private placement in February 2000 of 1,800,000 shares of Common Stock and
900,000 Class A Warrants for an aggregate purchase price of $10 million.

We face Year 2000 risks.

      Many currently installed computer systems and software products are unable
to distinguish between twentieth century dates and twenty-first century dates
because such systems may have been developed using two digits rather than four
to determine the applicable year. This could result in system failures or
miscalculations causing disruptions of operations, including, among other
things, a temporary inability to process transactions, send invoices or engage
in similar normal business activities. As a result, many companies' software and
computer systems may need to be upgraded or replaced to comply with such "Year
2000" requirements. Some of these concerns have continued to persist after
January 1, 2000. Our business depends on the operation of numerous systems that
could potentially be affected by Year 2000 related problems. Those systems
include hardware and software systems used internally by us in the management of
our business; hardware and software products developed by us; the internal
systems of our customers and suppliers; and non-information technology systems
and services used by us in the management of our business, such as telephone
systems and building systems. Success of our Year 2000 readiness efforts may
depend on the success of our customers in dealing with their Year 2000 issues.
Although we believe that our Year 2000 readiness efforts are designed to
appropriately identify and address those Year 2000 issues that


                                       8
<PAGE>

are within our control, there can be no assurance that our efforts will be fully
effective or that the Year 2000 issues will not have a material adverse effect
on our business, financial condition or results of operations. We do not
presently have a contingency plan for handling Year 2000 issues that are not
detected and corrected prior to their occurrence. Any failure by us to address
any unforeseen Year 2000 issue could adversely affect our business, financial
condition and results of operations.

Future sales of our common stock by our holders of outstanding stock, options
and warrants could have an adverse effect on the market price of our common
stock.

      We anticipate that some or all of the selling stockholders may from time
to time sell all or part of the shares offered hereby. In addition, there are
currently outstanding options or warrants to purchase 3,682,412 shares of our
common stock (comprised of 1,166,400 options granted under our 1996 Stock Option
Plan, 2,421,012 options and warrants held by selling stockholders with exercise
prices ranging from $1.50 to $8.84 per share and 95,000 options and warrants not
held by selling stockholders) and warrants to purchase an additional 495,000
shares of our common stock which are issuable upon exercise of certain
outstanding warrants with an exercise price of $21.22 per share. The market
price of our common stock could decline as a result of sales by our existing
stockholders of a large number of shares of common stock in the market after
this offering, or the perception that these sales may occur. These sales also
might make it more difficult for us to sell equity securities in the future at a
time and at a price that we deem appropriate.

Our stock price is volatile and could continue to be volatile.

      Investment interest in our common stock may not lead to the development of
an active or liquid trading market. The market price of our common stock has
fluctuated in the past and is likely to continue to be volatile and subject to
wide fluctuations. In addition, the stock market has experienced extreme price
and volume fluctuations. The stock prices and trading volumes for many "high
tech" companies fluctuate widely for reasons that may be unrelated to their
business or results of operations. The market price of our common stock may
decline below the offering price. General economic, market and political
conditions could also materially and adversely affect the market price of our
common stock and investors may be unable to resell their shares of common stock
at or above the offering price.

It may be difficult for a third party to acquire us.

      Provisions of Delaware law could make it more difficult for a third party
to acquire us, even if it would be beneficial to our stockholders.

Penny Stock Regulation may be applicable to investment in our shares.

      Broker-dealer practices in connection with transactions in "penny stocks"
are regulated by certain penny stock rules adopted by the Securities and
Exchange Commission. Penny stocks generally are equity securities with a price
of less than $5.00 (other than securities registered on certain national
securities exchanges or quoted on the Nasdaq system, provided that current
prices and volume information with respect to transactions in such securities
are provided by the exchange or system). The penny stock rules require a
broker-dealer, prior to a transaction in a penny stock not otherwise exempt from
the rules, to deliver a standardized risk disclosure document that provides
information about penny stocks and the risks in the penny stock market. The
broker-dealer also must


                                       9
<PAGE>

provide the customer with current bid and offer quotations for the penny stock,
the compensation of the broker-dealer and its salesperson in the transaction,
and monthly account statements showing the market value of each penny stock held
in the customer's account. In addition, the penny stock rules generally require
that prior to a transaction in a penny stock the broker-dealer make a special
written determination that the penny stock is a suitable investment for the
purchaser and receive the purchaser's written agreement to the transaction.
These disclosure requirements may have the effect of reducing the level of
trading activity in the secondary market for a stock that becomes subject to the
penny stock rules.

                 DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS

      This prospectus includes "Forward-Looking Statements" within the meaning
of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the
Securities Exchange Act of 1934, as amended. All statements other than
statements of historical facts included in this prospectus, including statements
regarding our future financial position, business strategy, budgets, project
costs and plans and objectives of management for future operations, are
Forward-Looking Statements. In addition, Forward-Looking Statements generally
can be identified by the use of forward-looking terminology such as "may,"
"will," "except," "should," "intend," "estimate," "anticipate," "believe," or
"continue" or their negatives or variations of these terms or similar
terminology. Although we believe that the expectations reflected in such
Forward-Looking Statements are reasonable, we can give no assurance that such
expectations will prove to have been correct. Important factors (or Cautionary
Statements) that could cause actual results to differ materially from our
expectations are disclosed under "Risk Factors" and elsewhere in this
prospectus. All subsequent written and oral Forward-Looking Statements
attributable to us, or to persons acting on our behalf, are expressly qualified
in their entirety by the Cautionary Statements.

                                 DIVIDEND POLICY

      We have never paid a cash dividend on our common stock. Payment of
dividends is at the discretion of the board of directors. The board of directors
plans to retain earnings, if any, for operations and does not intend to pay
dividends in the foreseeable future.

                                 USE OF PROCEEDS

      We will not receive any proceeds from the sale of common stock by the
selling stockholders. We may receive up to $11,557,865 in proceeds from the
exercise by certain of the selling stockholders of warrants to purchase up to an
aggregate of 2,421,012 shares of our common stock and an additional $10,503,900
upon exercise of 495,000 warrants issuable upon exercise of certain outstanding
warrants. The warrants have exercise prices ranging from $1.50 to $21.22 per
share and are exercisable until various dates through February 28, 2005 (and
with respect to the warrants issuable upon exercise of certain outstanding
warrants, three years after the issuance date). The resale of the common stock
underlying these warrants has been registered in the registration statement of
which this prospectus is a part.

                           PRICE RANGE OF COMMON STOCK

      Our common stock is traded on the OTC Electronic Bulletin Board of the
National Association of Securities Dealers, Inc., under the symbol "TTRE".
Although trading in our common stock has occurred on a relatively consistent
basis, the volume of shares traded has been sporadic.


                                       10

There can be no assurance that an established trading market will develop, that
the current market will be maintained or that a liquid market for our common
stock will be available in the future. Investors should not rely on historical
stock price performance as an indication of future price performance.

      The following table summarizes the high and low bid prices of TTR's common
stock as reported on the OTC Electronic Bulletin Board for the periods
indicated. The closing price of our common stock on March 10, 2000 was $8.6875
per share.

      The foregoing represent inter-dealer prices, without retail mark-up,
mark-down or commission, and may not necessarily represent actual transactions.

      As of March 9, 2000 there were approximately 173 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.


                      SELECTED CONSOLIDATED FINANCIAL DATA

            The following table sets forth our consolidated financial data for

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

      The following discussion should be read in conjunction with our
consolidated financial statements and the notes thereto included elsewhere in
this prospectus.

General

      We design and develop anti-piracy software technologies that provide copy
protection for electronic content distributed on optical media and over the
Internet. Our proprietary anti-piracy technology, MusicGuard, is a unique
hardware-based technology designed to prevent the unauthorized copying of audio
content distributed on CDs.

      As of November 24, 1999, we entered into an agreement with Macrovision
Corporation to jointly design and develop and market a copy protection product
designed to thwart the illegal copying of audio content on CDs, DVDs and other
optical media. Optical media store data which may be retrieved by utilizing a
laser and include compact discs which are commonly referred to as CDs and
digital versatile discs which are commonly referred to as DVDs. The new product
will be based primarily upon our MusicGuard technology, as well as related
Macrovision technology, and will be jointly owned by us and Macrovision. We
expect that the immediate application of the technology we are developing with
Macrovision will be of interest for the music distribution business and
recording studios whose products are customarily distributed on CDs. We granted
to Macrovision an exclusive world-wide royalty bearing license to design,
develop and market the copy protection technology which we are jointly
developing. The license to Macrovision relates to all technologies and products
designed to prevent the illicit duplication of audio programs (including the
audio portion of music videos, movies and other video or audio content)
distributed on optical media (not limited to CDs and DVDs) and technologies for
Internet digital rights management for audio applications. The proposed copy
protection technology we are developing with Macrovision will be transparent to
the legitimate end-user.

      Our immediate goal is to establish the proposed audio content protection
technology which we and Macrovision are developing as the leading product in the
target market of audio content copy protection for the high-volume recording
industry. Additionally, we are actively developing other technologies and
looking to acquire technologies which are synergistic with our current business
and will enable us to leverage our knowledge base and skill.

      We have not had any significant revenues to date. As of December 31, 1999,
we had an accumulated deficit of approximately $24.8 million. Our expenses have
related primarily to expenses related to and expenditures on research and
development, marketing, recruiting and retention of personnel, costs of raising
capital and operating expenses.

Revenue Sources

      We expect, for the near-term, that our primary source of revenue will be
royalties under our license agreements with Macrovision. We are currently
seeking to develop or


                                       12
<PAGE>

acquire other technologies that will provide other sources of revenue. However,
there can be no assurance that we will develop or acquire other technologies or
if we do, that such technologies will generate any revenue or profits.

Stock Based Compensation

      Compensation expense arising from stock grants, and options and warrants
issued at exercise prices below the quoted market price as of the date of grant
is recognized over the period that services are rendered. As more fully
described below in "Results of Operations," we have recorded expense in
connection with stock based compensation during 1997, 1998 and 1999.

Results of Operations

Year Ended December 31, 1999 Compared to Year December 31, 1998.

      Revenues for the year ended December 31, 1999 and 1998 were $68,803 and
$54,922, respectively and were derived from licensing fees of our DiscGuard
product.

      Research and development costs for the year ended December 31, 1999 were
$345,989 as compared to $1,017,073 for 1998. These decreases are attributable
primarily to reduced staffing effected in the latter part of 1998.

      Sales and marketing expenses for the year ended December 31, 1999 were
$815,586 as compared to $1,155,998 for 1998. This decrease was primarily due to
reduced staffing in 1999.

      General and administrative expenses for the year ended December 31, 1999
were $630,090 as compared to $1,663,912 for 1998. This decrease was primarily
due to reduced staffing in 1999.

      Stock-based compensation for the year ended December 31, 1999 was
$6,152,587 as compared to $1,341,889 for 1998. Due to the shortage of available
funds in 1999, we compensated employees and other consultants by issuing common
stock, warrants and options.

      Amortization of deferred financing costs for the year ended December 31,
1999 period was $4,180,540 as compared to $72,288 for the same period in 1998.
As a result of the issuance of 1.3 million warrants in connection with the sale
of our 10% Convertible Debentures, we recognized significant non-cash financing
costs. Using the Black-Scholes model for estimating the fair value of the
warrants, we recorded $3,845,400 as deferred financing costs and charged the
entire balance to operations when the debentures were converted.

      Interest expense for the year ended December 31, 1999 increased to
$1,019,937 as compared to $410,715 during 1998. Included in interest expense is
non-cash amortization of note discount in the amount of $272,009 and $214,454
for the years ended December 31, 1999 and 1998, respectively. Note discounts
were imputed to reflect the equity component of the related financings. Also
included in interest expense for 1999 was


                                       13
<PAGE>

$572,505, which represents the value of the beneficial conversion feature
relating to the conversion of outstanding debt into shares of our Common Stock.

      We reported a net loss for the year ended December 31, 1999 of $13,072,237
or $(2.07) per share on a basis and diluted basis, as compared to a net loss of
$5,578,540 or $(1.54) per share for the year ended December 31, 1998.

Year Ended December 31, 1998 Compared to Year December 31, 1997.

      We reported revenues for the first time in 1998, totaling $54,922. All of
the revenues were derived from license fees received from licensees of
DiscGuard.

      Research and development costs for the year ended December 31, 1998 were
$1,017,073 as compared to $957,232 for 1997. Research and development costs in
1998 were expended in developing improved versions of DiscGuard following its
commercial introduction in February 1998.

      Sales and marketing expenses for the year ended December 31, 1998 were
$1,155,998 as compared to $914,060 for 1997. This increase reflects our
intensified marketing activities when DiscGuard became commercially available in
the first quarter of 1998.

      General and administrative expenses for the year ended December 31, 1998
were $1,663,912 as compared to $604,151 for 1997. The increase in general and
administrative spending was primarily due to increased staffing, public
relations and professional fees relating to a proposed secondary public offering
of common stock in July 1998.

      Stock-based compensation for the year ended December 31, 1998 was
$1,341,889 and $1,309,192 for 1997.

      Interest expense for the year ended December 31, 1998 increased to
$410,715 as compared to $113,445 during 1997 due to the increase in debt
financing activity in the year. Included in interest expense is non-cash
amortization of note discount in the amount of $272,009 for the year ended
December 31, 1998. Note discounts were imputed to reflect the equity component
of the related financings.

      Interest income was $3,413 for the year ended December 31, 1998 as
compared to $42,069 for 1997. The decrease was a result of higher average cash
holdings during 1997.

      We reported a net loss for the year ended December 31, 1998 of $5,578,540,
or $(1.54) per share on a basic and diluted basis, as compared to a net loss of
$4,119,612, or $(1.35) per share for the year ended December 31, 1997.

Liquidity and Capital Resources

      At December 31, 1999, we had cash of approximately $210,000, representing
an increase of approximately $135,000 over December 31, 1998. In February 2000,
we completed a private placement of 1,800,000 shares of our common stock and
900,000 Class A Warrants for an aggregate purchase price of $10,000,000. The
Class A Warrants are exercisable for a period of five years at an exercise price
of $8.84 per share and upon exercise, we will issue Class B Warrants for an
additional


                                       14
<PAGE>

495,000 shares. The Class B Warrants are exercisable for a period of three years
from the date of issuance at an exercise price of $21.22. Under certain
circumstances the Class A and Class B Warrants may be redeemed.

      In November 1999, we signed an agreement with Macrovision Corporation
("Macrovision") to jointly develop and market music copy protection technology
for optical based media. In connection with the agreement, We granted to
Macrovision an exclusive world-wide, royalty-bearing license to use our
proprietary technology through December 31, 2009. We will be entitled to a 30%
royalty which may be adjusted to twenty five 25%, under certain conditions. Also
under certain conditions, the exclusive license may revert to a non-exclusive
license as of the second anniversary of the commercial launch of the product
that we are jointly developing. If certain conditions relating to the timing of
such commercial launch transpire, We will be entitled to minimum annual
guaranteed royalty advances, commencing on the first anniversary of the
Commercial Launch and continuing through the ninth year, aggregating $25
million.

      Also under the Agreement, in January 1999, Macrovision made a $4 million
equity investment in the Company for an 11.4% interest and received an exclusive
license to our proprietary DiscGuard(TM) technology.

      In the fourth quarter of 1999, we significantly reduced our accrued
interest and long-term debt through a series of conversions to Common Stock. We
also realized proceeds of approximately $1.4 from the exercise of outstanding
warrants and options.

                                    BUSINESS

Introduction

      We design and develop anti-piracy technologies that provide copy
protection for electronic content distributed on optical media and over the
Internet. Optical media store data which may be retrieved by utilizing a laser
and include compact discs which are commonly referred to as CDs and digital
versatile discs which are commonly referred to as DVDs. Our technologies utilize
both encryption and non-standard codewords on the optical media. As a result of
our research and development efforts we believe we have become the technological
leader in optical media authentication and verification. Our proprietary
anti-piracy technology, MusicGuard(TM), is a unique hardware-based technology
designed to prevent the unauthorized copying of audio content distributed on
CDs. MusicGuard leverages know-how we gained during the development of our
DiscGuard(TM) software protection product. Our copy protection technologies are
designed to be transparent to the legitimate end-user. Copy protected CDs are
compatible with and are designed to play on currently existing compact disc
players.

      As of November 24, 1999, we entered into an agreement with Macrovision
Corporation to jointly design and develop and market a copy protection product
designed to thwart the illegal copying of audio content on CDs, DVDs and other
optical media. The new product will be based primarily upon our MusicGuard
technology as well as related Macrovision technology. We granted to Macrovision
an exclusive world-wide royalty bearing license to market the copy protection
technology which we are jointly developing. The license to Macrovision relates
to all technologies and products designed to prevent the illicit duplication of
audio programs (including the audio portion of music videos, movies and other
video or audio content) distributed on optical media (not limited to CDs and
DVDs) and technologies for Internet digital rights management for audio


                                       15

applications.

      We are entitled to thirty percent (30%) of the net revenues collected by
Macrovision or its affiliates from any products or components incorporating the
proposed music protection technology. Under certain conditions, our share of the
net revenues may be readjusted to twenty-five percent (25%) of net revenues. We
agreed to reimburse Macrovision for up to $1 million of its costs incurred in
the twelve months ending December 31, 2000 in co-developing and commercially
launching MusicGuard.

      As part of the agreement, we granted to Macrovision an exclusive
world-wide license to modify and market DiscGuard, our software anti-piracy
product. Part of the DiscGuard technology license is royalty free. The
encryption portion is royalty bearing. Macrovision has its own proprietary
software anti-piracy product known as Safe Disc. For five years we are entitled
to 5% of Macrovision's net revenues, if any, collected by Macrovision from the
licensing of Safe Disc to customers located in the Peoples Republic of China.
Other than for these revenues we do not anticipate that we will receive any
significant revenues as a result of our license of DiscGuard to Macrovision.

      Macrovision develops and markets content copy protection and rights
management technologies and products to prevent the illicit duplication,
reception or use of video and audio programs and computer software. Macrovision
provides its products and services primarily to the consumer multimedia and
business software publishers, home video, pay-per-view, cable, satellite and
video security markets. Macrovision has its headquarters in Sunnyvale,
California with subsidiaries in London and Tokyo.

      Our immediate goal is to establish the proposed audio content copy
protection technology which we and Macrovision are developing as the leading
product in the target market of audio content copy protection for the
high-volume recording industry. Additionally, we are actively developing other
technologies and looking to acquire technologies which are synergistic with our
current business and will enable us to leverage our knowledge base and skill.

Industry Background

      Losses related to the unauthorized reproduction and use of music CDs
present a continuing concern for the recording industry as well as performing
artists. According to the Recording Industry Association of America, a national
trade organization, the recording industry loses about $5 billion annually to
global piracy of recorded music. Losses of up to $1 million a day have been
estimated in the U.S. alone. Two recent developments have exacerbated the
problem of piracy, causing it to become one the highest priorities of the
industry.

      First, the cost of producing good quality copies of CDs has been
drastically reduced. Until recently, to produce good quality CDs required a
significant investment. Recent developments in consumer electronics technology
have enabled consumers to purchase, for as little as $180, a CD burner
(recorder) from a local retail outlet. CD burners now often are bundled with new
computers. Blank recordable discs are widely available for less than $1. With
this technology, even the casual user can easily copy unprotected CDs.

      Second, it is now possible to easily download pirated music via the
Internet because of the acceptance and widespread use of MP3 compression
technology. This technology has made the


                                       16
<PAGE>

Internet a feasible vehicle for the electronic transmission of music. Today
there are thousands of websites offering music in MP3 format. Most of the music
being downloaded is pirated; i.e., no royalties are being paid to the artists or
to the record companies which produced this music. This form of piracy is
rapidly growing.

      Attempts by third parties to circumvent copy protection technologies have
been and are expected to be a persistent problem, even in the face of the United
States Digital Millennium Copyright Act, which was signed in October 1998. The
Act outlaws copy protection circumvention devices and technologies beginning in
May 2000 and provides for both criminal and civil penalties for companies or
individuals who import, produce or distribute devices designed to circumvent
copy protection devices and technologies.

      Since prior laws to combat music piracy have not served as an effective
deterrent and the effect of the new legislation cannot yet be ascertained,
recording studios and artists are seeking more effective methods to prevent the
replication of unauthorized copies of their proprietary products. To combat
music piracy, leaders of the music recording industry have cooperated with
leaders of more than 120 companies and organizations representing a broad
spectrum of information technology and consumer electronics businesses, Internet
service providers and security technology companies to form the Secure Digital
Music Initiative. The Initiative is a forum for these industries to develop the
voluntary, open framework for playing, storing and distributing digital music
necessary to enable a new market to emerge. The Initiative has already produced
a standard, or specification, for portable devices. The longer-term effort is
focused upon completion of an overall architecture for delivery of digital music
in all forms which system will include anti-piracy protection.

      The standard developed by the Initiative is intended to be applied to the
next generation of portable playback devices. It will not prevent currently
existing playback devices from playing pirated music. Since these devices will
likely be in use for quite some time we believe that there will be a need for
copy protection on the products played on the devices. To our knowledge there
are no commercially available technologies or products providing copy protection
for audio content distributed on CDs.

Our Solution

      We believe that the audio content copy protection which we and Macrovision
are jointly developing will offer recording studios and artists the most
effective solution to protect works distributed on CDs, while offering
convenience and cost effectiveness to the music rights owner and end-user. We
believe that the proposed technology embodies unique know-how designed to
prevent the unauthorized copying of CDs. The proposed music protection
technology will be based primarily on our proprietary technology, MusicGuard, as
well as related Macrovision technologies.

      Most music is currently offered for sale on a CD. To our knowledge, there
is no existing commercially available technology except MusicGuard, which
protects content on the original CD. Software-based technologies available today
claim to protect music during electronic transmission, but we believe that these
technologies are easily overcome. For example, according to an article appearing
in the August 18, 1999 edition of "Wired News", one month after Microsoft
released its software-based protection technology, Windows Media Audio, a
program was available on the Internet that removed the copying protection
afforded by the software. MusicGuard protection is embedded on the CD itself and
is introduced as part of the production process. The production process includes
the creation of a glass master from which metal molds, or stampers, used to mass


                                       17
<PAGE>

produce, or replicate, CDs are made.

      During the glass mastering process, a specially modified CD-encoder
introduces selective alternative alterations to the data placed on the glass
master. These alterations do not affect the audio quality of the original CDs in
any manner. CDs that will be protected by music copy protection technology we
are developing with Macrovision will be designed to play normally in the
currently existing CD and DVD players around the world. Music quality will not
be degraded as compared to the original. The technology will be designed so that
when one tries to make a copy of a protected CD with any of the many CD-to-CD
copying programs or "track rippers", the copy will be unusable. Either the
copying process itself will abort or the quality of the unauthorized copy will
be unacceptably inferior to the original music. Similarly, attempts to produce
MP3 files from a protected CD will either fail or result in inferior and
unusable audio. We will design the technology so that it will be easy to apply
and use. Record companies or recording studios need only inform an authorized
glass mastering facility that it wishes to protect against copying with the
technology. We don't envision any special preparation or changes that will be
needed to be made to the data which the recording mastering studio supplies to
the glass mastering facility. The technology will leverage existing encoder
technology used in our DiscGuard(TM) software protection product. Glass
mastering facilities worldwide will be able to simply, cheaply and immediately
upgrade their existing encoders to enable the use of the copy protection
technology. Since the protection will be applied only during the glass mastering
process, once a glass master and stampers have been produced, protected discs
can be mass-produced by any replicator. We are working together with Macrovision
and the encoder manufacturers to develop the most efficient and effective
manufacturing solution.

Mastering Equipment Manufacturers

      In order to produce protected CDs, modifications to the encoder portion of
the laser optics system in CD mastering equipment are required. Under our
contract with Macrovision, Macrovision is responsible for coordinating with the
companies which produce and sell these encoders. We believe that three
companies, Doug Carson & Associates, Media Morphics and Eclipse, effectively
control the market for encoders. We will work with Macrovision and these encoder
producers to develop the necessary modifications to produce protected CDs.

      We envision that Macrovision will authorize licensed CD replicators to
replicate protected CDs. Macrovision has licensing arrangements in place with
more than 75 replication facilities worldwide including the largest
multinational replicators such as, Sonopress, MPO, Americ Disc, Nimbus, Cinram,
and JVC. Therefore, we believe that Macrovision is in a good position to
leverage its current business relationships to the benefit of the audio content
copy protection technology we will develop with Macrovision.

Marketing and Sales

      Under our agreement with Macrovision, Macrovision will be responsible, at
its expense, for the marketing of the proposed audio content copy protection
technology and will determine the staffing and other resources to be allocated
to the commercialization of the technology consistent with Macrovision's good
faith determination of its commercial potential.

      Macrovision markets its products, including video cassettes, digital PPV
and DVD copy protection and video scrambling technologies, through a combination
of direct sales and licensing


                                       18
<PAGE>

as well as through independent distributors. Macrovision has a network of
authorized duplication, authoring and replication facilities throughout the
world.

      We are entitled to thirty percent (30%) of the net revenues received by
Macrovision from customers, distributors, OEM partners or other sublicensees of
the jointly developed technology. Under certain conditions, our share of net
revenues may be adjusted to twenty-five percent (25%) of the net revenues. Under
certain circumstances, the exclusive license relating to MusicGuard and the
jointly developed technology which we granted to Macrovision reverts to a
non-exclusive license as of the second anniversary of the commercial launch.
Under our agreement with Macrovision, commercial launch is deemed to occur when
a certain pre-designated number of protected music CDs are manufactured, with a
certain specified number being manufactured by at least one of certain
designated major commercial music labels. If certain conditions relating to the
timing of the commercial launch transpire, we will be entitled to minimum annual
guaranteed royalty advances, recoupable against royalties actually earned by us,
commencing on the first anniversary of the commercial launch and continuing
through the term of the development agreement which ends on December 31, 2009.

      Macrovision markets its video and consumer protection technologies
internationally from its Sunnyvale, California headquarters and through its
subsidiaries in Japan and the United Kingdom. It supplements its direct sales
efforts with a variety of marketing initiatives, including trade show
participation, trade advertisements, industry education and news letters.
Macrovision provides technical support to its licensed duplicators, including
hardware installation assistance and quality control. As of December 1, 1999,
Macrovision employed 33 sales and marketing personnel and 38 additional
employees who assisted in customer support and operations.

      We have only a limited internal sales and marketing capability. To
maintain our focus on product development and to avoid the expense of
establishing our own global sales and marketing staff, we do not anticipate
expanding our marketing capability until we are in a position to commercialize
products other than MusicGuard.

Research And Development

      We intend to maintain our position as the technological leader in
anti-piracy products by leveraging our existing knowledge base and skillset and
exploiting to the fullest our existing technologies. We are interested in
acquiring or establishing business arrangements with other parties which have
promising technologies that offer synergy to our technological and commercial
expertise. We are particularly focusing upon companies in Israel due to their
geographic proximity and because Israel has a large pool of startup companies
with raw technologies from which to choose.

      The software and entertainment industries in general are characterized by
rapid product changes resulting from new technological developments, performance
improvements and lower production costs. Our research and development activities
have focused on developing products responsive to perceived immediate market
demands. We believe that our future growth in anti-piracy products will depend
in large part on our ability to develop and apply our proprietary technology and
know-how. We believe that the key to ensuring that the audio content copy
protection technology we are developing with Macrovision becomes the industry
standard for CD copy protection lies in our and Macrovision's ability to
continually enhance and upgrade our unique anti-piracy technologies.


                                       19

New Products and Technologies

      We intend to extend our range of activities in two specific directions:

      o     Exploiting existing technologies and expertise - the development and
            commercialization of products which are similar to and share common
            distribution channels with MusicGuard.

      o     Other technologies - the result of cooperation with outside parties,
            including applications which offer synergy with MusicGuard.

We have developed other technologies with applications in the following areas:

      o     DiscAudit - a system for identifying genuine disc replicas. During
            the mastering process, a special non-reproducible authenticating
            mark is embedded outside the data portion of the disc. The
            authenticating mark is not present in unauthorized replicas. By
            means of a laptop with CD or DVD drive and software supplied by us,
            law enforcement authorities, including customs inspectors, can
            quickly determine the authenticity of a disc. DiscAudit is
            applicable to CD and DVD, including both software and audio discs.
            The product has been tested with fully satisfactory results. Unlike
            the following three technologies, this technology is not subject to
            the right of first refusal we have granted to Macrovision to acquire
            rights in the technology if we decide to license or sell our rights
            in it.

      o     Encryption Engine - a strong encryption engine for a variety of
            applications including electronic software distribution, secure
            electronic music distribution, dedicated music and video playback
            devices and dedicated games machines. We can supply the encryption
            technology and software library for the content to be protected.

      o     Smart Card Application Binding - Our DiscGuard technology "binds" a
            protected application to a signature on an authentic optical disc so
            that the protected application runs correctly only in the presence
            of the disc. In many applications, it would be desirable to run the
            protected application on any PC. This can be accomplished by
            transferring binding information to the user's smart card. Use of
            smart cards is expected to grow substantially. Reading devices are
            inexpensive and readers are included in Microsoft's PC hardware
            specifications. The binding could be by direct download via the
            Internet. For example, an end user can download a demo version of
            sample music. If he chooses, he can unlock the application by an
            on-line registration process that transmits the unlock key directly
            to the end users's smart card. As a result, the end user has
            complete mobility - he can run the application from any Internet
            connected PC, while the music publisher has no concerns about
            unauthorized replication.

      o     Dedicated Playback Devices with Smart Card - GSM (Global System for
            Mobile Communications) modules throughout the world work with small
            smart card modules containing the user's authorization and personal
            preferences. We intend to extend this concept to a wide range of
            consumer devices, including computers, video and audio playback
            devices and game stations. In all cases, protected content such as
            software, video, audio or games, must be bound to the user's smart
            card before it can be played correctly. The binding can be achieved
            by leveraging our existing encryption and binding


                                       20
<PAGE>

            mechanisms.

      Under our agreement with Macrovision, we granted to Macrovision an
exclusive right of first refusal through December 31, 2009, to any music copy
protection technology that we develop which is not included in the license to
Macrovision, and any Internet digital rights management technologies developed
by us which are applicable to music, music video, video, software or data
publishing products or markets. We are required to notify Macrovision of the
details of any bona- fide third party offers to purchase or license such
technologies. If Macrovision notifies us of its interest in such purchase or
license within 10 business days of Macrovision's receipt of our notification, we
are required to negotiate in good faith with them such purchase or license. The
encryption engine, smart card application binding and the GSM systems are
subject to Macrovision's first refusal rights.

      A major part of future business strategy will be the identification and
setting up of cooperation arrangements with the developers of technologies,
including those that share our anti- piracy theme.

      We are already active in the process of screening potential partners. The
model will be to invest in such companies and to allow them to benefit from our
strengths - technical knowledge (especially in optical media), professional
management, market awareness and established relationship with Macrovision and
other marketing partners. We believe that we can identify several early stage
technology companies and can provide the added value necessary to achieve
success and cut time to market.

      In connection with the design and development of DiscGuard, our
proprietary software anti- piracy product, our Israeli subsidiary has received a
grant of $210,000 from the Chief Scientist of the State of Israel. We are
required to pay royalties to the Chief Scientist on proceeds from the sale of
products derived from the research and development funded by the grant at the
rate of 3% of the sales revenue for the first three years of such sales, 4% for
the following three years, and 5% thereafter, up to a maximum of 100% of the
grant. For example, royalties will be payable to the Chief Scientist based on
royalties we receive from Macrovision relating to DiscGuard. We do not believe
that any royalties are payable to the Chief Scientist in respect of the proposed
audio content protection technology. Our obligation to pay royalties to the
Chief Scientist is limited to the amount of the grant received and is linked to
the exchange rate of the dollar and the New Israeli Shekel. The Chief Scientist
places certain restrictions on companies that receive funding relating to the
transfer of know-how. We believe that these restrictions and obligations will
not have a material adverse effect on our operations since we do not presently
anticipate transferring ownership of the technology developed by us to third
parties. The restrictions do not apply to the exports from Israel of products
developed with such technologies.

      From the date of inception through December 31, 1999, we have expended
approximately $3 million on research and development activities, including
approximately $2.6 million through the year ended December 31, 1998, and
approximately $.4 million for the year ended Dectember 31, 1999. We expect to
maintain our research and development expense at approximately the current level
for the foreseeable future.

      We are a member of the Software and Information Industry Association and
of the Israeli Export Institute.

Competition

      We are not aware of the existence of any commercially available
anti-piracy technologies in the area of copy protection for electronic content
distributed on optical media. There can be no assurance that other companies
will not enter the market in the future, particularly if the audio content
protection technology we are developing with Macrovision is successfully
commercialized. There can be no assurance that we will be able to continue
developing products with innovative features and functions, or that development
by others of similar or more effective products will not render our products or
technologies noncompetitive or obsolete.

Proprietary Rights

      We currently rely on a combination of trade secret, copyright and
trademark law, as well as non-disclosure agreements and invention-assignment
agreements, to protect the technologies used in our products and other
proprietary information. We have filed patent applications in the United States
and Israel and under the Patent Cooperation Treaty with respect to the
technology underlying DiscGuard and in Israel for MusicGuard. We have also
applied for a United States trademark registration of MusicGuard. There can be
no assurance that any patent or trademark will be issued or that our proprietary
technology will remain a secret or that others will not develop similar
technology and use such technology to compete with us.

      We believe that our software and audio content protection products and
technologies are proprietary and are protected by copyright law, non-disclosure
and secrecy agreements. We also rely on proprietary know-how and employ various
methods, such as proper labeling of confidential documents and non-disclosure
agreements, to protect our processes, concepts, ideas and documents associated
with proprietary products. However, such methods may not afford complete
protection and there can be no assurance that others will not independently
develop such processes, concepts, ideas and documentation.

      Our policy is to require our employees, consultants, and other advisors to
execute confidentiality agreements upon the commencement of employment,
consulting or advisory relationships with us. These agreements generally provide
that all confidential information developed or made known to the individual by
us during the course of the individual's relationship with us is to be kept
confidential and not to be disclosed to third parties except in specific
circumstances. In the case of employees and consultants, the agreements provide
that all inventions conceived by the individual in the course of their
employment or consulting relationship with us shall be our exclusive property.
There can be no assurance, however, that these agreements will provide
meaningful protection or adequate remedies for our trade secrets in the event of
unauthorized use or disclosure of such information.

Employees

      We have 5 full-time employees, all of whom work in Israel. None of our
employees is covered by a collective bargaining agreement or is represented by a
labor union. We have not experienced any organized work stoppages and consider
our relations with our employees to be good.

      Our future performance depends highly upon the continued service of
members of our senior management and of Dr. Baruch Sollish, our
Vice-President-Research and Development, in particular.


                                       22

We believe that our future success will also depend upon our continuing ability
to identify, attract, train and retain other highly skilled managerial,
technical, sales and marketing personnel. Hiring for such personnel is
competitive, and there can be no assurance that we will be able to retain our
key employees or attract, assimilate or retain the qualified personnel necessary
for the development of its business.

Properties

      We lease a 2400 square foot facility used in our research and development
and administrative activities in Kfar Saba, Israel. The lease provides for a
monthly rent of approximately $2292 and an expiration date of May 31, 2000
subject to one optional annual renewal through May 2001. We have improved this
facility to meet the requirements of our research and development activities. We
believe that this facility is sufficient to meet our current and anticipated
future requirements. We believe that we will be able either to renew our present
lease or obtain suitable replacement facilities. In the opinion of management,
our leased facility is adequately covered by insurance.

                              CONDITIONS IN ISRAEL

      The following information discusses certain conditions in Israel that
could affect our Israeli subsidiary, TTR Technologies, Ltd. All figures and
percentages are approximate. A portion of the information with respect to Israel
presented hereunder has been taken from Annual Reports of the Bank of Israel and
publications of the Israeli Central Bureau of Statistics.

Political Conditions

      Since the establishment of the State of Israel in 1948, a number of armed
conflicts have taken place between Israel and its Arab neighbors and a state of
hostility, varying from time to time in intensity and degree, has led to
security and economic problems for Israel. However, a peace agreement between
Israel and Egypt was signed in 1979, a peace agreement between Israel and Jordan
was signed in 1994 and, since 1993, several agreements between Israel and the
Palestine Liberation Organization --Palestinian Authority representatives have
been signed. In addition, Israel and several other Arab states have announced
their intention to establish trade and other relations and are discussing
certain projects. As of the date of this prospectus, although Israel and Syria
have resumed negotiations, Israel has not entered into any peace agreement with
Syria or Lebanon. Recently there has been stagnation in the peace process in the
Middle East. There can be no assurance as to whether or how the "peace process"
will develop or what effect it may have upon us. Beginning in 1948, nearly all
Arab countries formally adhered to a boycott of Israel and Israeli companies
and, since the early 1950's of non-Israeli companies doing business in Israel or
with such companies. Despite measures to counteract the boycott, including
anti-boycott legislation in the United States, the boycott has had an
indeterminate negative effect upon trade with and foreign investment in Israel.
We do not believe that the boycott has had a material adverse effect on us, but
there can be no assurance that restrictive laws, policies or practices directed
toward Israel or Israeli businesses will not have an adverse impact on the
operation or expansion of our business.

      Generally, all male adult citizens and permanent residents of Israel under
the age of 54 are, unless exempt, obligated to perform certain military duty
annually. Additionally, all such residents are subject to being called to active
duty at any time under emergency circumstances. Some of the employees of our
Israeli subsidiary currently are obligated to perform annual reserve duty. While


                                       23
<PAGE>

our Israeli subsidiary has operated effectively under these and similar
requirements in the past, no assessment can be made of the full impact of such
requirements on us in the future, particularly if emergency circumstances occur.

Economic Conditions

      Israel's economy has been subject to numerous destabilizing factors,
including a period of rampant inflation in the early to mid-1980s, low foreign
exchange reserves, fluctuations in world commodity prices, military conflicts,
security incidents and for at least the five years preceding 1997, expansion.
The Israeli government has, for these and other reasons, intervened in the
economy by utilizing, among other means, fiscal and monetary policies, import
duties, foreign currency restrictions and control of wages, prices and exchange
rates. The Israeli government periodically changes its policies in all these
areas.

      The economic recession which began in 1997 continued during 1998, with a
further decline in the rate of GDP growth and an increase in unemployment,
despite a significant decrease in the balance of payments deficit and in the
growth rate of the public sector deficit. These developments reflect the
continued slow growth of domestic demand, the global economic slowdown,
instability in international financial markets and continued tight fiscal and
monetary policies aimed at maintaining economic stability and achieving budget
deficit and inflation targets determined by the government. Other factors
contributing to the continued economic slowdown were security and political
uncertainty, and changes in the labor market, such as increases in the minimum
wage and public sector employment.

      Despite improvements during 1998, Israel maintains a significant balance
of payments deficit, primarily as a result of its defense burden, the absorption
of immigrants, especially from the former Soviet Union, the provision of a
minimum standard of living for lower income segments of the community and the
maintenance of a minimum level of net foreign reserves. In order to finance this
deficit, Israel must sustain an adequate inflow of capital from abroad. The
major sources of the country's capital imports include U.S. military and
economic aid, personal remittances from abroad, sales of Israeli government
bonds (primarily in the United States) and loans from foreign governments,
international institutions and the private sector.

Assistance From The United States

      The State of Israel receives significant amounts of economic and military
assistance from the United States, averaging approximately $3 billion annually
over the last several years. In addition, in 1992, the United States approved
the issuance of up to $10 billion in loan guarantees during United States fiscal
years 1993-1998 to help Israel absorb a large influx of new immigrants,
primarily from the republics of the former Soviet Union. Under the loan
guarantee program, Israel may issue up to $2 billion in principal amount of
guaranteed loans each year, subject to reduction in certain circumstances. There
is no assurance that foreign aid from the United States will continue at or near
amounts received in the past. If the grants for economic and military assistance
or the United States loan guarantees are eliminated or reduced significantly,
the Israeli economy could suffer material adverse consequences.

Trade Agreements


                                       24
<PAGE>

      Israel is a member of the United Nations, the International Monetary Fund,
the International Bank for Reconstruction and Development and the International
Finance Corporation. Israel is also a signatory to the General Agreement on
Tariffs and Trade, which provides for reciprocal lowering of trade barriers
among its members. In addition, Israel has been granted preferences under the
Generalized System of Preferences from the United States, Australia, Canada and
Japan. These preferences allow Israel to export the products covered by such
programs either duty-free or at reduced tariffs.

      Israel and the European Union concluded a Free Trade Agreement in July,
1975 which confers certain advantages with respect to Israeli exports to most
European countries and obligates Israel to lower its tariffs with respect to
imports from these countries over a number of years.

      In 1985, Israel and the United States entered into an agreement to
establish a Free Trade Area, under which most products received immediate
duty-free status, and by 1995 all other tariffs and certain non-tariff barriers
on most trade between the two countries were ultimately eliminated.

      On January 1, 1993, an agreement between Israel and EFTA, which at present
includes Norway, Switzerland, Iceland and Liechtenstein, established a
free-trade zone between Israel and the EFTA nations.

      In recent years, Israel has established commercial and trade relations
with a number of other nations, including Russia, China and nations in Eastern
Europe, with which Israel had not previously had such relations.

Employees

      Our Israel subsidiary is subject to various Israeli labor laws and
collective bargaining agreements between Histadrut and the federation of
industrial employers. Such laws and agreements cover a wide range of areas,
including hiring practices, wages, promotions, employment conditions (such as
working hours, overtime payment, vacations, sick leave and severance pay),
benefits programs (such as pension plans and education funds) and special
issues, such as equal pay for equal work, equal opportunity in employment and
employment of women. The collective bargaining agreements also cover the
relations between management and the employees' representatives, including
Histadrut's involvement in certain aspects of hiring and dismissing employees
and procedures for settling labor disputes. Our Israel subsidiary continues to
operate under the terms of Israel's national collective bargaining agreement,
portions of which expired in 1994. Israeli employers and employees are required
to pay predetermined sums to the National Insurance Institute, an organization
similar to the United States Social Security Administration. These contributions
entitle the employees to receive a range of medical services and other benefits.
Certain employees of our Israel subsidiary are covered by individual employment
agreements.

Stock Option Plans

      1996 Stock Option Plan. Our 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.


                                       28
<PAGE>

      We have adopted our 1996 Incentive and Non-Qualified Stock Option Plan.
The 1996 Option Plan provides for the grant to qualified employees (including
officers and directors) of options to purchase shares of our common stock. A
total of 1,500,000 shares of our common stock have been reserved for issuance
upon exercise of stock options granted under the 1996 Option Plan.

      The 1996 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 1996 Option Plan. Options
granted under the 1996 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 incentive stock
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). 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 1996 Option Plan may be exercised, or (ii) extend the
dates during which all, or any particular, option or options granted under the
1996 Option Plan may be exercised, provided, that no such extension will be
permitted if it would cause the 1996 Option Plan to fail to comply with Section
422 of the Code or with Rule 16b-3 of the Securities 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 1996 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 us 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 1996
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 1996 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 January 31, 2000, options to purchase 1,166,400 shares of our common
stock were outstanding under the 1996 Option Plan.

      Non-Executive Directors Stock Option Plan. We adopted our 1998
Non-Executive Director Stock Option Plan in July 1998 to provide an incentive
for attracting and retaining on our board the service of qualified individuals
who are not otherwise employed by us or any subsidiary.

      The Directors Plan is administered by the Board of Directors. We have
reserved 25,000 shares of our common stock under the Directors Plan for issuance
upon the exercise of stock options. Options are exercisable upon the date of
grant and expire five years from the date of grant. Upon termination of a
person's services as a director, the options expire within two months of such
termination. The exercise price of the option will be the fair market value of
our common stock on the date of the grant of the option. The number of options
and prices at which they are exercisable are subject to adjustment in the case
of certain transactions such as mergers, recapitalizations, stock splits or
stock dividends. No options may be granted under the Directors Plan after July
2008. As

of March 1, 2000, no options were outstanding under the Directors Plan.

Employment Agreements

      Our Israeli subsidiary signed an employment agreement in August 1994 with
Marc Tokayer, pursuant to which Mr. Tokayer is employed as its General Manager
for a term which is automatically renewable from year to year unless either
party gives notice of termination at least 90 days prior to the current
expiration date. Mr. Tokayer currently receives an annual salary of $120,000,
subject to increase and the grant of a performance bonus in the Board's
discretion. If Mr. Tokayer is terminated other than for engaging in willful
misconduct or acts of bad faith or conviction of a felony, he will be entitled
to continue to receive his salary and benefits for an additional 12 months,
subject to certain limitations.

      We signed an employment agreement with Emanuel Kronitz as of June 1, 1999,
pursuant to which Mr. Kronitz is employed as our Chief Operating Officer. The
agreement is for a term of one year and is automatically renewable for
additional one year terms, unless terminated by either party upon 90 days prior
notice. Mr. Kronitz is paid a monthly salary of $5,000 plus benefits.

      Our Israeli subsidiary entered into an employment agreement with Dr.
Baruch Sollish in December 1994 which was amended in July 1998. Pursuant to the
agreement Dr. Sollish is employed as Director of Product Research and
Development of our Israeli subsidiary. The agreement is renewable for terms of
three years, subject to termination by either party on not less than 60 days
notice prior to the end of any term. The current term expires on December 1,
2001. Dr. Sollish currently receives an annual base salary of $120,000 subject
to increase and the grant of a performance bonus in the board's discretion.

      Each of the executives with an agreement has agreed to certain customary
confidentiality and non-compete provisions that prohibit him from competing with
us for one year, or soliciting our employees for one year, following the
termination of his employment.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS


      As of November 24, 1999, we entered into an agreement with Macrovision
Corporation to jointly design and develop and market a copy protection product
designed to thwart the illegal copying of audio content on CDs, DVDs and other
optical media. The new product will be based primarily upon our MusicGuard
technology as well as related Macrovision technology. We granted to Macrovision
an exclusive world-wide royalty bearing license to market the copy protection
technology which we are jointly developing. The license to Macrovision relates
to all technologies and products designed to prevent the illicit duplication of
audio programs (including the audio portion of music videos, movies and other
video or audio content) distributed on optical media (not limited to CDs and
DVDs) and technologies for Internet digital rights management for audio
applications.

      We are entitled to thirty percent (30%) of the net revenues collected by
Macrovision or its affiliates from any products or components incorporating the
proposed music protection technology. Under certain conditions, our share of the
net revenues may be readjusted to twenty- five percent (25%) of net revenues. We
agreed to reimburse Macrovision for up to $1 million of its costs incurred in
the twelve months ending December 31, 2000 in co-developing and commercially
launching MusicGuard.

      As part of the agreement, we granted to Macrovision an exclusive
world-wide license to modify and market DiscGuard, our software anti-piracy
product. Part of the DiscGuard technology license is royalty free. The
encryption portion is royalty bearing. Macrovision has its own proprietary
software anti-piracy product known as Safe Disc. For five years we are entitled
to 5% of Macrovision's net revenues, if any, collected by Macrovision from the
licensing of Safe Disc to customers located in the Peoples Republic of China.
Other than for these revenues we do not anticipate that we will receive any
significant revenues as a result of our license of DiscGuard to Macrovision.

      Under the terms of the agreement, we also granted to Macrovision first
refusal rights until December 31, 2009 with respect to any music protection
technology we develop which is not included in the license to Macrovision and
any Internet digital rights management technologies we develop which are
applicable to music, music video, video, software or data publishing products or
markets. These rights include rights of ownership if we decide to sell the
technology or worldwide exclusive marketing or distribution rights if we decide
to license the technology. Our obligation is to negotiate a sale or license to
Macrovision in good faith should we receive a bona fide offer from a third party
to purchase or license the technology and should Macrovision notify us of its
interest in acquiring the technology.

      On January 12, 2000 pursuant to stock purchase agreement we sold to
Macrovision $4 million of our common stock, and granted to Macrovision rights of
first refusal to purchase equity securities (including securities convertible or
exchangeable into common stock) we propose to sell to third parties if the
amount of the securities to be sold would constitute a majority of our
outstanding common stock. Subject to some exceptions, we further granted to
Macrovision a right to purchase its pro rata share (based on Macrovision's then
current ownership of common stock) of any equity securities we offer in private
transactions above a certain amount. Macrovision waived its right of first
refusal with respect to our private placement in February 2000 of 1,800,000
shares of Common Stock and 900,000 Class A Warrants for an aggregate purchase
price of $10 million.


      In January 2000, we issued to Mr. Tokayer, options under the 1996 Stock
Option Plan to purchase 347,000 shares of our common stock at an exercise price
per share of $4.00, of which options to purchase 173,000 shares were vested upon
issuance and options to purchase 174,000 shares will vest over 12 months.

      In February 1999, we issued to Dr. Sollish options to purchase 50,000
shares of our common stock. All of the options vested at the time they were
issued. In November 1999, we issued to Dr. Sollish options to purchase 80,000
shares of our common stock under the 1996 Stock Option Plan, with 20,000 of
these options being vested upon issuance with an exercise price of $.01 per
share and 60,000 of these options vesting over a 3 year period with an exercise
price per share of $2.56. In January 2000, we issued to Dr. Sollish additional
options to purchase 70,000 shares of our common stock under our 1996 Stock
Option Plan, of which 30,000 options were fully vested upon grant at an exercise
price of $4 per share, 20,000 options were fully vested upon grant at an
exercise price of $.01 per share and the remaining 20,000 options with an
exercise price of $.01 per share will vest upon the commercial launch of the
audio content protection product being jointly developed by us and Macrovision.

      In June 1999, we granted options to purchase 235,000 shares of our common
stock under the 1996 Stock Option Plan to Emanuel Kronitz, our Chief Operating
Officer, which options were to vest, subject to Mr. Kronitz's continued
employment with us, in 36 equal monthly installments and have an exercise price
of $.01 per share. On January 12, 2000, at the direction of the board, the
options were amended to provide that 150,000 of Mr. Kronitz's options became
vested and the balance of 85,000 options will vest in one lump sum on November
12, 2000. In November, 1999, we issued to Mr. Kronitz fully vested options to
purchase an additional 69,500 under the 1996 Stock Option Plan at an exercise
price of $.01 per share.

      Marc D. Tokayer, Chairman of the Board, The Tokayer Family Trust, Baruch
Sollish, director, and four other stockholders with an aggregate of 1,137,430
shares of our common stock, entered into a voting arrangement dated August 10,
1996, whereby they agreed to vote their respective shares to elect directors and
in support of positions favored by a majority of the shares held among them.
This arrangement was terminated in July 1999.

      In November 1999, we issued to Gershon Tokayer, our sales manager and the
brother of Marc D. Tokayer, the Chairman of the Board, options to purchase
249,500 shares of our common stock under the 1996 Stock Option Plan, of which
options to purchase 209,500 shares were immediately vested upon issuance at an
exercise price of $.01 per share and 40,000 options were to vest over a 3 year
period at an exercise price of $2.56 per share.

*     Indicates less than 1%.

(1) Beneficial ownership is determined in accordance with the rules of the SEC
and generally includes voting or investment power with respect to securities. In
accordance with SEC rules, shares which may be acquired upon exercise of stock
options which are currently exercisable or which become exercisable within 60
days after the date of the information in the table are deemed to be
beneficially owned by the optionee. Except as indicated by footnote, and subject
to community property laws where applicable, to our knowledge, the persons or
entities named in the table above are believed to have sole voting and
investment power with respect to all shares of common stock shown as
beneficially owned by them.

(2) For purposes of calculating the percentage of outstanding shares held by
each person named below, any shares which such person has the right to acquire
within 60 days after the date of the information in the table are deemed to be
outstanding, but not for the purpose of calculating the percentage ownership of
any other person.

(3) Assumes the sale of all of the shares offered hereby.

(4) Includes 503,202 shares issuable upon exercise of warrants. As required by
SEC rules, the number of shares shown as beneficially owned includes shares
which could be purchased within 60 days after the date of this prospectus.
However, the terms of the warrants held by this selling stockholder specify that
the stockholder can not exercise its warrants to the extent that such exercise
would result in the selling stockholder and its affiliates beneficially owning
more than 4.99% of our then outstanding common stock. Thus, although some of the
shares listed in the table might not be subject to purchase by the selling
stockholder during that 60 day period, they are nevertheless included in this
table. The actual number of shares of common stock issuable upon the exercise of
the warrants is subject to adjustment and could be materially less or more than
the number estimated in the table. This variation is due to factors that cannot
be predicated by us at this time. The most significant of these factors is the
future market price of our common stock.

Kfar Saba, Israel.

                            DESCRIPTION OF SECURITIES

Common Stock

      We are authorized to issue 25,000,000 shares of common stock, $.001 par
value per share, of which 15,967,890 shares were outstanding and held of record
as of March 8, 2000 by approximately 173 stockholders of record. A significant
portion or our common stock is held in either nominee name or street name
brokerage accounts. Holders of shares of common stock are entitled to one vote
for each share held of record on all matters to be voted on by stockholders.
There are no preemptive, subscription, conversion or redemption rights
pertaining to the shares of common stock. Holders of shares of common stock are
entitled to receive dividends when, as and if declared by the Board of Directors
from funds legally available therefor and to share ratably in our assets
available upon liquidation, dissolution or winding up. The holders of shares of
common stock do not have cumulative voting rights for the election of directors
and, accordingly, the holders of more than 50% of the shares of common stock are
able to elect all directors.


                                       35
<PAGE>

Preferred Stock

      We are authorized to issue 5,000,000 shares of preferred stock, $.001 par
value per share, of which no shares are issued and outstanding. The shares of
preferred stock may be issued from time to time in one or more series, in any
manner permitted by law, as determined from time to time by the Board of
Directors, and stated in the resolution or resolutions providing for the
issuance of such shares adopted by the Board of Directors pursuant to authority
vested in it. Without limiting the generality of the foregoing, shares in such
series shall have voting powers, full or limited, or no voting powers, and shall
have such designations, preferences and relative, participating, optional, or
other special rights, and qualifications, limitations, or restrictions thereof,
permitted by law, as shall be stated in the resolution or resolutions providing
for the issuance of such shares adopted by the Board of Directors. The number of
shares of any such series so set forth in the resolution or resolutions may be
increased (but not above the total number of authorized shares of preferred
stock) or decreased (but not below the number of shares thereof then
outstanding) by further resolution or resolutions adopted by the Board of
Directors.

Effect of Delaware Anti-takeover Statute

      We are subject to Section 203 of the Delaware General Corporation Law (the
anti-takeover law), which regulates corporate acquisitions. The anti-takeover
law prevents certain Delaware corporations from engaging under certain
circumstances in a "business combination" with any "interested stockholder" for
three years following the date that such stockholder became an interested
stockholder. For purposes of the anti- takeover law, a "business combination"
includes, among other things, a merger or consolidation involving us and the
interested shareholder and the sale of more than 10% of our assets. In general,
the anti-takeover law defines an "interested stockholder" as any entity or
person beneficially owning 15% or more our outstanding voting stock and any
entity or person affiliated with or controlling or controlled by such entity or
person. A Delaware corporation may "opt out" of the anti-takeover law with an
express provision in its original certificate of incorporation or an express
provision in its certificate of incorporation or bylaws resulting from
amendments approved by the holders of at least a majority of our outstanding
voting shares. We have not "opted out" of the provisions of the anti-takeover
law.

Anti-takeover Effects of By-laws

      Under Delaware law, all stockholder actions must be effected at a duly
called annual or special meeting or by written consent. Our by-laws provide
that, except as otherwise required by law, special meetings of the stockholders
can only be called by the president, the Board of Directors, the Chairman of the
Board, the President or the holders of a majority of all shares entitled to vote
at the meeting.

Transfer Agent

      North America Transfer Co., 147 W. Merrick Road, Freeport, New York, is
the transfer agent for our common stock.

Certain Limited Liability and Indemnification Provisions

      Pursuant to our Certificate of Incorporation and By-laws, as amended, our
officers and directors shall be indemnified by us to the fullest extent allowed
under Delaware law for claims brought against them in their capacities as
officers and directors. Indemnification is not allowed if the officer or
director does not act in good faith and in a manner reasonably believed to be in
our best interests, or if the officer or director had no reasonable cause to
believe his conduct was lawful. Accordingly, indemnification may occur for
liabilities arising under the Securities Act. Insofar as indemnification for
liabilities arising under the Securities Act may be permitted for our directors,
officers and controlling persons pursuant to the foregoing provisions or
otherwise, we have been advised that in the opinion of the SEC, such


                                       36
<PAGE>

indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable.

                              PLAN OF DISTRIBUTION

      As used in this prospectus, stockholders selling our shares pursuant to
this prospectus includes donees and pledgees selling shares received after the
date of this prospectus from a selling stockholder named in this prospectus.
Upon our being notified by a selling stockholder that a donee or pledgee intends
to sell more than 500 shares, a supplement to this prospectus will be filed.

      We have agreed to bear all costs, expenses and fees of registration of the
shares of common stock offered by the selling stockholders for resale other than
the legal fees and expenses of counsel or other advisors to the selling
stockholders. Any brokerage commissions, discounts, concessions or other fees,
if any, payable to broker-dealers in connection with any sale of the shares of
common stock will be borne by the selling stockholders selling those shares or
by the purchasers of such shares.

      Sales of shares may be effected by selling stockholders from time to time
in one or more types of transactions, including block transactions,
over-the-counter markets, negotiated transactions, put or call options on the
shares and short sales of shares. Shares may be sold at market prices prevailing
at the time of sale or at negotiated prices. The stockholders selling shares
pursuant to this prospectus may effect such transactions by selling shares
directly to purchasers or to or through broker-dealers as principals or agents
or to broker-dealers who may purchase shares of common stock as principals and
thereafter sell the shares from time to time in any one or more of such
transactions. In effecting sales, broker-dealers engaged by a selling
stockholder may arrange for other broker-dealers to participate. Such
brokers-dealers may receive compensation in the form of discounts, concessions
or commissions from the selling stockholders and/or the purchasers of the shares
for whom such broker-dealers may act as agents or to whom they may sell as
principals, or both (which compensation, as a particular broker-dealer, might be
in excess of customary commissions). The selling stockholders have advised us
that they have not entered into any agreements, understandings or arrangements
with any underwriters or broker-dealers regarding the sale of their shares, nor
is there an underwriter or coordinating broker acting in connection with the
proposed sale of shares by the selling stockholders.

      The selling stockholders and any broker-dealers that act in connection
with the sale of shares might be deemed to be "underwriters" within the meaning
of Section 2(11) of the Securities Act. We have agreed to indemnify those
selling stockholders who were issued common stock upon conversion of 10%
Convertible Debentures due April 30, 2001 against certain liabilities, including
liabilities arising under the Securities Act. The selling stockholders may agree
to indemnify any agent, dealer or broker-dealer that participates in
transactions involving sales of the shares against certain liabilities,
including liabilities arising under the Securities Act.

      Because selling stockholders may be deemed to be "underwriters" within the
meaning of Section 2(11) of the Securities Act, the selling stockholders will be
subject to the prospectus delivery requirements of the Securities Act. We have
informed the selling stockholders that the anti-manipulative provisions of
Regulation M promulgated under the Exchange Act may apply to their sales in the
market.

      Selling stockholders also may resell all or a portion of the shares under
this prospectus in open market transactions in reliance upon Rule 144 under the
Securities Act, provided they meet the criteria and conform to the requirements
of that rule.

      Upon our being notified by a selling stockholder that any material
arrangement has been entered


                                       37
<PAGE>

into with a broker-dealer for the sale of shares through a block trade, special
offering, exchange distribution or secondary distribution or a purchase by a
broker or dealer, a supplement to this prospectus will be filed, if required,
pursuant to Rule 424(b) under the Act, disclosing:

      o     The name of each such selling stockholder and of the participating
            broker-dealer(s);

      o     The number of securities involved;

      o     The price at which such securities were sold;

      o     The commissions paid or discounts or concessions allowed to such
            broker-dealer(s), where applicable;

      o     That such broker-dealer(s) did not conduct any investigation to
            verify the information set out or incorporated by reference in this
            prospectus; and

      o     Other facts material to the transaction.

      We have agreed to indemnify certain selling stockholders or their
transferees or assignees against certain liabilities, including liabilities
under the Securities Act of 1933, or to contribute to payments to which such
selling stockholders or their respective pledgees, donees, transferees or other
successors in interest may be required to make in respect thereof.

      Certain of our stockholders holding a total of approximately 991,800
shares have agreed not to sell more than 25% of the shares offered by such
selling stockholder under this prospectus in any 30 day period. Each of such
other selling stockholders who holds warrants has also agreed not to sell any of
the common stock underlying such warrants for 30 days after the effective date
of this prospectus. Each of our directors and principal officers has undertaken
that, without the prior consent of these stockholders, he will not sell or
otherwise transfer or offer to sell or otherwise transfer (except in a private
transaction in which the transferee agrees to be bound by such restriction) any
shares of common stock directly or indirectly held by him prior to April 6,
2000.

      All of the purchasers of an aggregate of 1,800,000 shares of our Common
Stock and 900,000 Class A Warrants sold in a private placement closed on
February 25, 2000 have agreed not to sell such shares or shares of Common Stock
issuable upon exercise of such warrants until after May 25, 2000.

                                  LEGAL MATTERS

      The legality of the securities offered by this prospectus will be passed
upon for us by Wolf, Block, Schorr and Solis-Cohen LLP, New York, New York.

                                     EXPERTS

      The consolidated financial statements of TTR Technologies, Inc. for the
three years ended December 31, 1999, included in this prospectus, have been
included in reliance upon the report of Brightman Almagor & Co., a member of
Deloitte Touche Tohmatsu, independent certified public accountants, given upon
the authority of said firm as experts in accounting and auditing.


                                       38

Auditor Change

      On June 30, 1998, we appointed Brightman Almagor & Co. to re-issue a
report on our consolidated financial statements for the year ended December 31,
1997. On July 3, 1998, Schneider Ehrlich & Wengrover LLP (or SE&W) resigned as
our independent auditors by mutual agreement. The decision to change accountants
was approved by the Board of Directors.

      During the fiscal years ended December 31, 1997 and 1996 and the period
between January 1, 1998, up to and including the day of its resignation, there
were no disagreements between us and SE&W on any matter of accounting principles
or practices, financial statement disclosure or auditing scope or procedures
which if not resolved to SE&W's satisfaction would have caused them to make
reference in connection with their opinion to the subject matter of the
disagreement. SE&W's report on our financial statements for such fiscal years
indicated that substantial doubt exists regarding our ability to continue as a
going concern.

      The audit of Brightman Almagor & Co., a member of Deloitte Touche
Tohmatsu, as our independent accountants did not result in any changes to such
financial statements, and the related audit report of Brightman Almagor & Co., a

                         REPORT OF INDEPENDENT AUDITORS

To the Board of Directors and
Shareholders of TTR Technologies, Inc.

We have audited the accompanying consolidated balance sheets of TTR
Technologies, Inc. (formerly, TTR Inc.) ("the Company") (a development-stage
company) as of December 31, 1998 and 1999, and the related consolidated
statements of operations, comprehensive loss, stockholders' deficit and cash
flows for the three years ended December 31, 1999. These consolidated financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing standards
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 the Company's 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 aforementioned consolidated financial statements present
fairly, in all material respects, the consolidated financial position of the
Company as of December 31, 1998 and 1999, and the consolidated results of
operations, and its cash flows for the three years ended December 31, 1999, in
conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 - DESCRIPTION OF BUSINESS

      TTR Inc. (the "Company") was incorporated on July 14, 1994 under the laws
      of the State of Delaware. In December 1998 the Company amended its
      certificate of incorporation to change its name to TTR Technologies, Inc.

      TTR Technologies Ltd., ("TTR Ltd.") was formed under the laws of the State
      of Israel on December 5, 1994 as a wholly owned research and development
      subsidiary of the Company.

      The Company is engaged in the design, development and commercialization of
      proprietary software security products.

      The Company is considered to be in the development stage and has earned
      limited revenues to date. Business activities to date have focused on
      product and marketing research, product development, and raising capital.


NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      Principles of Consolidation

      The consolidated financial statements include the accounts of the Company
      and its wholly owned subsidiary, TTR Ltd. All significant intercompany
      accounts and transactions have been eliminated in consolidation. Certain
      consolidated amounts have been reclassified for consistent presentation.

      Use of Estimates

      Management uses estimates and assumptions in preparing these financial
      statements in accordance with generally accepted accounting principles.
      Those estimates and assumptions affect the reported amounts of assets and
      liabilities, the disclosure of contingent assets and liabilities and the
      reported revenues and expenses. Actual results could vary from the
      estimates that were used.

      Cash Equivalents

      Cash equivalents consist of short-term, highly liquid debt investments
      that are readily convertible into cash with original maturities when
      purchased of three months or less.

      Fair Value of Financial Instruments

      Substantially all of the Company's financial instruments, consisting
      primarily of cash equivalents, current receivables, accounts payable and
      accrued expenses, are carried at, or approximate, fair value because of
      their short-term nature or because they carry market rates of interest.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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

      Revenue Recognition

      In October 1997, the American Institute of Certified Public Accountants
      issued Statement of Position (SOP) 97-2, "Software Revenue Recognition".
      SOP 97-2 provides guidance in recognizing revenue on software transactions
      and is required for transactions entered into after December 15, 1997.
      Subsequently, in March 1998 and December 1998, the AICPA issued SOP 98-4
      and SOP 98-9, respectively, which defer until the Company's fiscal year
      beginning January 1, 2000, the application of several paragraphs and
      examples in SOP 97-2. Management does not believe that the adoption of the
      remaining portions of SOP 97-2, which were deferred by SOP 98-4 and SOP
      98-9, will have a material impact on the Company's financial statements.

      Revenues are generated from licensing software and are recognized upon
      delivery to the customer, provided no significant obligations of the
      Company remain and collection for the resulting receivable is probable.

      Stock Based Compensation

      The Company accounts for stock based compensation under the provisions of
      Statement of Financial Accounting Standards No. 123, "Accounting for
      Stock-Based Compensation" (SFAS 123). As permitted by SFAS 123, the
      Company has elected to continue to follow Accounting Principles Board
      Opinion No. 25, "Accounting for Stock Issued to Employees" (APB 25) and
      related interpretations in accounting for stock based compensation to
      employees. Accordingly, compensation cost for stock options granted to
      employees is measured as the excess, if any, of the quoted market price of
      the Company's Common Stock at the measurement date (generally, the date of
      grant) over the amount an employee must pay to acquire the stock. This
      amount is recognized over the vesting periods of the related grants.

      Stock options granted to non-employees are valued using a Black-Scholes
      option pricing model with appropriate assumptions for risk free investment
      rates, expected lives, dividend yields and volatility factors. The value
      of options granted to non-employees is charged to appropriate asset or
      expense accounts when the options are granted.

      Foreign Currency Translations

      The financial statements of TTR Ltd. have been translated into U.S.
      dollars in accordance with Statement No. 52 of the Financial Accounting
      Standards Board (FASB). Assets and liabilities have been translated at
      year-end (period-end) exchange rates and statements of operations have
      been translated at average rates prevailing during the year. The
      translation adjustments have been recorded as a separate component of
      stockholders' deficit (cumulative translation adjustment).

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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

      Net Loss Per Share

      The Company has adopted the provisions of Statement of Financial
      Accounting Standards No.128 (SFAS 128) "Earnings per Share". SFAS 128
      requires dual presentation of basic and diluted earnings per share (EPS)
      for complex capital structures on the face of the Statements of
      Operations. Basic EPS is computed by dividing net income (loss) by the
      weighted-average number of common shares outstanding for the period.
      Diluted EPS reflects the potential dilution from the exercise or
      conversion of other securities into common stock. None of the stock
      options and warrants issued have been included in the net loss per share
      computation for the period, because their inclusion would be
      anti-dilutive.

      Depreciation and Amortization

      Equipment, vehicles and leasehold improvements are stated at cost.
      Equipment and vehicles are depreciated over the estimated useful lives of
      the related assets, which range from three to fourteen years. Leasehold
      improvements are amortized over the related lease term. Depreciation is
      computed on the straight-line method.

      Research and Development Costs

      Research and development expenditures are charged to operations as
      incurred. Software development costs are required to be capitalized when a
      product's technological feasibility has been established by completion of
      a working model of the product and ending when a product is available for
      general release to customers. To date, completion of a working model of
      the Company's products and general release have substantially coincided.
      As a result, the Company has not capitalized any software development
      costs since such costs have not been significant.

      Income Taxes

      The Company uses the liability method to determine its income tax expense
      as required under the Statement of Financial Accounting Standards No. 109,
      (SFAS 109). SFAS 109 requires the establishment of a deferred tax asset or
      liability for the recognition of future deductible or taxable amounts and
      operating loss carryforwards. Deferred tax expense or benefit is
      recognized as a result of the changes in the assets and liabilities during
      the year. Valuation allowances are established when necessary, to reduce
      deferred tax assets, if it is more likely than not that all or a portion
      of it will not be realized.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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

      Long-Lived Assets

      In accordance with SFAS No. 121, "Accounting for the Impairment of
      Long-Lived Assets and for Long-Lived Assets to be Disposed of", the
      Company records impairment losses on long-lived assets used in operations
      when events and circumstances indicate that the assets might be impaired
      and the undiscounted cash flows estimated to be generated by those assets
      are less than the carrying amounts of those assets.

      Comprehensive Income (Loss)

      In January 1998, the Company adopted SFAS 130, "Reporting Comprehensive
      Income," which establishes standards for reporting the components of
      comprehensive income. The foreign currency translation adjustment is the
      Company's only component of comprehensive income.

      Recently Issued Accounting Pronouncements

      In June 1998, the Financial Accounting Standards Board issued SFAS No.
      133, "Accounting for Derivative Instruments and Hedging Activities," which
      establishes accounting and reporting standards for all derivative
      instruments. SFAS No. 133 is effective for fiscal years beginning after
      June 15, 1999. The Company believes that the adoption of SFAS No. 133 on
      January 1, 2000 will not have a significant effect on its financial
      statements.

NOTE 3 - PROPERTY AND EQUIPMENT

      Property and equipment consist of the following:

      (a)   In June 1999, the Company received notice from a shareholder,
            threatening to commence litigation, alleging that the Company failed
            to register its stock. The shareholder was seeking the return of its
            investment in the amount of $ 400,000 plus interest to date. In
            November 1999 the Company settled the matter, and agreed to pay a
            total of $ 200,000 over specified periods, and to issue a total of

NOTE 5 - ACCRUED SEVERANCE PAY

      Under Israeli law, TTR Ltd. is required to make severance payments to
      dismissed employees (including officers) and to employees leaving
      employment under certain other circumstances. This liability is calculated
      based on the years of employment for each employee, in accordance with the
      "severance pay laws." The Company's liabilities for required severance
      payments are covered by funding into severance pay funds and the purchase
      of insurance policies.

            connection with the loan, the company also sold to the investor
            111,111 shares of Common Stock at par. For financial reporting
            purposes, the Company recorded a note discount totaling $ 87,500, to
            reflect the value of the stock. The discount was amortized on a
            straight-line basis over the term of the note.

      (a)   The loan is denominated in New Israeli Shekels (NIS), bears interest
            at the Israeli prime rate (at December 31, 1999 - 12.2%) plus 3% per
            annum, and are secured by substantially all the assets of TTR Ltd..
            Principal payments are due in various installments through 2001.

      (b)   From April through August 1998, the Company realized gross proceeds
            of $ 1,462,500 from a private offering of 29.25 Units, each Unit
            consisting of a $ 50,000 10% Promissory Note and Warrants to
            purchase 11,500 shares of Common Stock. The exercise price of the
            warrant is $ 1.50 per share. For financial reporting purposes, the
            Company recorded a discount of $ 357,450, to reflect the value of
            the Warrants. The discount was being amortized on a straight-line
            basis over the terms of the respective notes. The notes and accrued
            interest were due at the earlier of one year or 30 days following
            any public or private equity or debt financing exceeding $
            1,000,000.

            In December 1999, the Company offered any remaining note holders an
            option to convert their outstanding principal and accrued interest
            to shares of common stock. The conversion rate was based on 85% of
            the average closing bid price of the common shares for the 30
            trading days preceding the date of conversion. In accordance with
            applicable accounting rules, the Company recorded a charge to
            interest expense in the amount of $ 572,505 to reflect this
            beneficial conversion feature. A total of $ 1,329,202 of note
            principal and accrued interest was converted to common stock.

      Long-Term Debt (contd.)

      (c)   In December 1998, the Company realized gross proceeds of $ 150,000
            from a private offering of 5 Units, each Unit consisting of a $
            30,000 8% Promissory Note, 9,000 shares of Common Stock and Warrants
            to purchase an additional 3,000 shares. For financial reporting
            purposes, the Company recorded a note discount of $ 41,513, to
            reflect the value of the Stock and Warrants. The discount was being
            amortized on a straight-line basis over the term of the notes. In
            November 1999, the entire principal balance plus accrued interest on
            these notes was repaid.

      The aggregate maturities of long-term debt for the next two years ending
      December 31, are as follows: 2000 - $ 7,764; and 2001 - $ 8,219.

      10% Convertible Debentures

      In May 1999 the Company agreed to issue $ 2,000,000 of its 10% Convertible
      Debentures to private investors. The Debentures were convertible into
      shares of the Company's Common Stock at the rate of $ 0.77 per share based
      on the closing trading prices of the Common Stock during certain specified
      periods. In addition, upon conversion, warrants were issued to purchase
      additional shares of Common Stock equal to one-half of the shares of
      Common Stock issued. The warrants were exercisable at a price per share
      equal to 120% of the conversion rate and expire in April 2002.

      In October and November 1999, the investors converted all of the
      outstanding debentures and were issued 2,681,934 shares of common stock
      and 1,340,967 warrants exercisable at $ 0.92 per share. In November 1999,
      the investors exercised of all the outstanding conversion warrants.

      In connection with the sale of Debentures, the Company also issued
      warrants to purchase up to 1.3 million shares of Common Stock to an
      independent consultant. These warrants expire in April 2002 and are
      exercisable at a nominal price per share. Using the Black-Scholes model
      for estimating the fair value of the warrants, the Company recorded $
      3,845,400 as deferred financing costs. This amount was charged to
      operations in the period the debentures were converted.

NOTE 7 - INCOME TAXES

      At December 31, 1999, the Company had available $ 6,475,000 of net
      operating loss carryforwards for U.S. federal income tax purposes which
      expire in the years 2014 through 2019, and $ 6,822,000 of foreign net
      operating loss carryforwards with no expiration date. Due to the
      uncertainty of their realization, no income tax benefit has been recorded
      by the Company for these net operating loss carryforwards as valuation
      allowances have been established for any such benefits. The use of the
      U.S. federal net operating loss carryforwards is subject to limitations
      under section 382 of the Internal Revenue code pertaining to changes in
      stock ownership.

      Significant components of the Company's deferred tax assets for U.S.
      federal and Israel income taxes are as follows:

NOTE 8 - STOCKHOLDERS' EQUITY

      Stock Options

      1996 Incentive and Non-Qualified Stock Option Plan

      In July 1996, the Board of Directors adopted the Company's Incentive and
      Non-qualified Stock Option Plan (the " Plan") and has reserved up to
      450,000 shares of Common Stock for issuance thereunder. In December 1999,
      the Plan was amended to increase the total number of shares available for
      grant to 1,500,000. The Plan provides for the granting of options to
      officers, directors, employees and advisors of the Company. The exercise
      of incentive stock options ("ISOs") issued to employees who are less than
      10% stockholders shall not be less than the fair market value of the
      underlying shares on the date of grant or not less than 100% of the fair
      market value of the shares in the case of an employee who is a 10%
      stockholder. The exercise price of restricted stock options shall not be
      less than the par value of the shares to which the option relates. Options
      are not exercisable for a period of one year from the date of grant.
      Thereafter, options may be exercised as determined by the Board of
      Directors, with maximum terms of ten and five years, respectively, for
      ISOs issued to employees who are less than 10% stockholders and employees
      who are 10% stockholders. The Plan will terminate in 2006.

      Stock Options (contd.)

      1996 Incentive and Non-Qualified Stock Option Plan (contd.)

      In 1997, the Company granted 60,000 options with an exercise price below
      the fair value of the underlying common stock. The issuance of the options
      resulted in a charge to deferred compensation in the amount of $ 300,000
      which was being amortized over the vesting period. In 1999, the Company
      granted 534,000 $ 0.01 options under the Plan, which were immediately
      exercisable to employees. The issuance of the options resulted in a charge
      to stock based compensation in the amount of $ 1,502,610. Included in this
      amount, were 209,500 options granted to an employee who is also the
      brother of the Company's president and chief executive officer.

      A total of 24,000 stock options granted to non-employees in 1997 resulted
      in a charge to deferred compensation of $ 53,032, which is being amortized
      over the four-year vesting period.

      Non-Executive Directors Stock Option Plan

      In July 1998, the Board of Directors adopted the Non-Executive Directors
      Stock Option Plan ("the Directors' Plan") and has reserved up to 25,000
      shares of common stock for issuance thereunder. The plan provides for the
      grant of options to directors who are not otherwise employed by the
      Company. Options are exercisable upon the date of grant and expire five
      years from the date of the grant. Upon the termination of director, the
      options expire within two months of such termination. The exercise price
      of the option will be the fair market value of the share on the date of
      the grant of the option. The Plan will terminate in 2008. As of December
      31, 1999, no options had been granted under the Directors' Plan.

      Other Option Grants

      In 1997, the Company issued options to purchase 217,473 shares to the
      Chief executive Officer of TTR Ltd. The options have an exercise price of
      $ 0.01 per share and vest over a four- year period. The issuance of the
      options resulted in a charge to deferred compensation expense of $
      1,522,300 which was being amortized over the vesting period. In November
      1998 the officer resigned and a settlement agreement was executed.
      Pursuant to the agreement, 48,328 options were cancelled and the remaining
      169,145 become exercisable at various dates in 1999.

      In 1999, the Company issued non-plan options to purchase 196,000 shares to
      various employees . The options have an exercise price of $ 0.01 per share
      and vested immediately. The issuance of these options resulted in a charge
      to stock based compensation in the amount of $ 163,660.

      The Company has adopted the pro forma disclosure provisions of SFAS No.

      months from the date of issuance at an exercise price per share of $21.22.
      The Class B Warrants may be redeemed by the Company if the underlying

Item 14. Indemnification of Directors and Officers.

      Section 145 of the General Corporation Law of the State of Delaware (the
"Delaware Corporation Law") empowers a Delaware corporation to indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of the corporation) by reason of the fact that he is or was a director,
officer, employee or agent of the corporation, or is or was serving at the
request of the corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation, and with respect to any criminal action or proceeding had no
reasonable cause to believe his conduct was unlawful. The termination of any
action, suit or proceeding by judgment, order, settlement, conviction, or upon
plea of nolo contendere or its equivalent, does not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had
reasonable cause to believe that his conduct was lawful.

      In the case of an action by or in the right of the corporation, Section
145 empowers a corporation to indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or complete action in
any of the capacities set forth above against expenses (including attorneys'
fees) actually and reasonably incurred by him in connection with the defense or
settlement of such action or suit if he acted in good faith and in a manner he
reasonably believed to be in and not opposed to the best interests of the
corporation, except that indemnification is not permitted in respect of any
claim, issue or matter as to which such person is adjudged to be liable to the
corporation unless and only to the extent that the Court of Chancery or the
court in which such action or suit was brought determines upon application that,
despite the adjudication of liability, but in view of all of the circumstances
of the case, such person is fairly and reasonably entitled to indemnity for such
expenses which the Court of Chancery or such court deems proper. Section 145
further provides: that a Delaware corporation is required to indemnify a
director, officer, employee or agent against expenses (including attorneys'
fees) actually and reasonably incurred by him in connection with any action,
suit or proceeding or in defense of any claim,


                                      II-1
<PAGE>

issue or matter therein as to which such person has been successful on the
merits or otherwise; that indemnification provided for by Section 145 not be
deemed exclusive of any other rights to which the indemnified party may be
entitled; that indemnification provided for by Section 145 shall, unless
otherwise provided when authorized or ratified, continue as to a person who has
ceased to be a director, officer, employee or agent and shall inure to the
benefit of such person's heirs, executors and administrators; and empowers the
corporation to purchase and maintain insurance on behalf of a director or
officer against any such liability asserted against him in any such capacity or
arising out of his status as such whether or not the corporation would have the
power to indemnify him against liability under Section 145. A Delaware
corporation may provide indemnification only as authorized in the specific case
upon a determination that indemnification of the director, officer, employee or
agent is proper in the circumstances because he has met the applicable standard
of conduct. Such determination is to be made (i) by a majority vote of the
directors who are not parties to such action, suit or proceeding, even through
less than a quorum or (ii) if there are no such directors, or if such directors
so direct, by independent legal counsel in a written opinion or (iii) by the
stockholders.

      Section 6 of the Certificate of Incorporation of TTR Technologies, Inc.
("TTR") provides that:

            "To the fullest extent that the General Corporation Law of the State
            of Delaware, as the same exists or may hereafter be amended, permits
            elimination or limitation of the liability of directors, a director
            of the corporation shall not be personally liable to the corporation
            or any of its shareholders for any breach of duty in his capacity as
            a director. Any repeal or modification of the foregoing sentence by
            the shareholders of the corporation shall not adversely affect any
            right or protection of a director of the corporation existing at the
            time of such repeal or modification."

      Section 102(b)(7) of the Delaware Corporation Law provides that the
Certificate of Incorporation of a Delaware corporation may contain a provision
eliminating the personal liability of a director to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
provided that such provision shall not eliminate or limit the liability of a
director for (i) any breach of the director's duty of loyalty to the corporation
or its stockholders, (ii) acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) the payment of
unlawful dividends or the making of unlawful stock purchases or redemptions or
(iv) any transaction from which the director derived a personal benefit.

      Section 7 of the Certificate of Incorporation of TTR contains the
following provisions with respect to the elimination or limitation of liability
of our directors:

            "The directors and officers of the corporation shall be entitled to
            such rights of indemnification and advancement of expenses,
            including attorneys' fees, in the defense of any action or
            threatened action in which a director or officer is or may be a
            party as the Board of Directors may by resolution prescribe."

      Our By-Laws provide that we will indemnify our directors, executive
officers, other officers, employees and agents to the fullest extent permitted
by law.

      Item 17. Undertakings.

      The undersigned registrant hereby undertakes:

      (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:

            (i) To include any prospectus required by Section 10(a)(3) of the
      Securities Act of 1933;

            (ii) To reflect in the prospectus any facts or events arising after
      the effective date of the registration statement (or the most recent
      post-effective amendment thereof) which, individually or in the aggregate,
      represent a fundamental change in the information set forth in the
      registration statement. Notwithstanding the foregoing, any increase or
      decrease in volume of securities offered (if the total dollar value of
      securities offered would not exceed that which was registered) and any
      deviation from the low or high end of the estimated maximum offering range
      may be reflected in the form of prospectus filed with the Commission
      pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
      price represent no more than 20 percent change in the maximum aggregate
      offering price set forth in the "Calculation of Registration Fee" table in
      the effective registration statement.

            (iii) To include any material with respect to the plan of
      distribution not previously disclosed in the registration statement or any
      material change to such information in the registration statement;

      (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

      (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

      Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provision described under Item 14 or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. If a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the


                                     II-11
<PAGE>

opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

      the contrary contained in the foregoing, neither TTR nor Macrovision shall
      use or otherwise exploit the Joint Technology except as expressly provided
      hereunder. Except as set forth explicitly herein (including without
      limitation Section 5.1 and 5.2 hereof), neither Party will be entitled to

<PAGE>

      compensation with respect to any sale, distribution, license or other
      exploitation by the other Party of the Joint Technology. Notwithstanding
      the foregoing, during the term of this Agreement, TTR will not transfer,
      license, distribute or disclose to any third party the Joint Technology in
      the Field of Use, in whole or in part, or any products incorporating such
      Joint Technology, in any manner. TTR and Macrovision shall each retain the
      right to use or otherwise exploit the Joint Technology outside of the
      Field of Use, however, TTR's right to use or otherwise exploit the Joint
      Technology outside the Field of Use shall be subject to the terms of this
      Agreement (including without limitation Section 4.5).

      3.4 Patent Rights. Macrovision and TTR will file and prosecute, and shall

      States of America, Canada, Mexico, United Kingdom, France, Benelux,
      Scandinavia, Germany, Spain, Italy, Korea and Japan, Australia, Argentina,
      and Brazil any patents on the Macrovision Technology or the TTR
      Technology, respectively, which the Parties agree, are commercially
      important to protecting the intellectual property rights of the Music
      Protection Technology. Except as prohibited by law, the Parties shall
      jointly file, with respect to Joint Technology, such patent and copyright
      applications and amendments thereof as the Parties agree are useful to
      protect their joint interests in the Music Protection Technology, and
      shall thereafter use commercially reasonable and diligent efforts to
      prosecute and maintain in force such applications and any resultant
      patents and copyrights. The costs and expenses (including attorneys' fees)
      incurred in the filing, prosecution and maintenance of such patents and
      copyrights shall be shared equally by the Parties. Macrovision will
      undertake the administrative efforts required to give effect to this
      Section. As an additional right, either Party, at its own expense, may
      file patent and copyright applications covering the Music Protection
      Technology in those countries where the Parties do not mutually agree to
      file such applications. All patent and copyright applications for Joint
      Technology developed under this Agreement shall be filed in the name of
      both Parties.

4.    License Grants

      exclusive, non-transferable, royalty-free, worldwide license to use, copy,
      modify, improve and create derivative works based on the Macrovision
      Technology solely for the purposes of performing its obligations in
      connection with the development of the Music Protection Technology. The
      license granted under this Section shall not be construed so as to grant
      TTR any commercial rights to the Macrovision Technology other than as
      expressly set out in this Agreement.

      4.2 TTR Technology. Subject to the terms and conditions set forth herein,
      TTR hereby grants to Macrovision an exclusive, royalty bearing, worldwide
      license, within the Field of Use (a) to use, copy, modify and improve the
      Joint Technology and the TTR Technology and create derivative works based
      thereon solely in connection with the development of the Music Protection
      Technology, and (b) to make, have made, sublicense and distribute the TTR
      Technology and any derivative works thereof embodied in the Music
      Protection Technology. No right is being granted to sublicense or
      distribute the TTR Technology (or components thereof) as stand-alone
      products outside the Field of Use, except as otherwise expressly provided
      in Section 4.4 of this Agreement. The Parties acknowledge that a copy of
      the TTR Technology, as set out in Exhibit C hereof, has been delivered to
      Macrovision. TTR will apprise Macrovision of any material improvements or
      developments relating to the Music Protection Technology of which TTR
      becomes aware within thirty (30) days of such improvement or development.
      TTR will not deliver to Macrovision without Macrovision's prior written
      consent any technology pertaining to MusicGuard which requires the payment
      of royalties to a third party; alternatively, if TTR does deliver to
      Macrovision any such royalty-bearing technology, payment of such royalties
      will be the responsibility of TTR. Further, TTR will not deliver to
      Macrovision without Macrovision's prior written consent any technology
      pertaining to DiscGuard which requires the payment of royalties to a third
      party. The Parties expressly acknowledge that DiscGuard includes a
      component known as Gearworks which is licensed by a third party.

      4.3 Trademark Licenses. TTR hereby grants Macrovision the exclusive right
      to use the TTR trademark "MUSIC GUARD" ("TTR Mark") in marketing and
      distributing the Music Protection Technology. Macrovision shall have the
      the right, in its sole discretion, to market the Music Protection
      Technology or the CD Technology (as defined in Section 4.4) under its
      trade names and trademarks or under the TTR Mark.

      4.4 TTR's Other Technology. Effective upon the Investment Date, TTR grants
      Macrovision an exclusive, worldwide license (with the right to sublicense)
      to (a) use, copy, modify, and create derivative works based on TTR's
      CD-ROM software copy protection technology as further described in Exhibit
      F ("CD Technology"), including but not limited to its CD and DVD
      signatures, encoder modules and other technology; (b) incorporate the CD
      Technology (or components thereof) into or bundle the CD Technology with
      Macrovision products; and (c) market, sublicense and distribute the CD
      Technology alone or with or incorporated in Macrovision bundled products.
      TTR shall, within 20 business days following the Investment Date, deliver
      to Macrovision all materials, notes, plans, diagrams, schematics, source
      code, object code and technical specifications related to the CD
      Technology, including but not limited to the


                                       6
<PAGE>

      digital signature portions thereof. The license granted in this Section
      shall be royalty-free with respect to the CD and DVD signature portions of
      the CD Technology and shall be royalty bearing with respect to all other
      portions of the CD Technology, such royalty to be negotiated separately
      between the Parties. Except for the licenses named in the marketing
      agreements listed in Exhibit G, TTR shall, within seven (7) business days
      of the closing of the Investment Date, notify all existing CD Technology
      customers and prospective customers that, after sixty (60) days of such
      notice, TTR will no longer license or support the CD Technology, and that
      TTR encourages such customers to license Macrovision's Safe Disc
      Technology (defined in Section 5.3) from Macrovision. TTR further agrees
      to work cooperatively with Macrovision to encourage Sonopress and Nimbus
      to cease offering or marketing the CD Technology within such sixty day
      period and in any event agrees to remit to Macrovision 100% of any
      revenues related to the CD Technology which TTR receives from Sonopress or
      Nimbus subsequent to the Investment Date.

      4.5 Other TTR Technologies. TTR grants to Macrovision an exclusive right
      of first refusal, during the term of this Agreement, with respect to the
      acquisition of all rights in or worldwide exclusive marketing and
      distribution rights to: (i) the Music Protection Technology outside of the
      Field of Use and/or (ii) any future packaged media copy protection or
      internet digital rights management technologies developed by TTR which are
      applicable to music, music video, video, software or data publishing
      products or markets. In addition, TTR shall notify Macrovision of any
      bona-fide third party offers to purchase or license any such technology,
      including the terms of such offer. If Macrovision notifies TTR of its
      interest in such purchase or license under the terms of such offer within
      ten (10) United States business days of Macrovision's receipt of such
      notification, the Parties will negotiate in good faith a definitive
      agreement for the purchase or license.

5.    Royalties

      5.1   Amounts.

            (a) Royalty Rate. Except as provided below in this Section 5,
            Macrovision or its Affiliates agree to pay to TTR thirty percent
            (30%) of the Net Revenues received by Macrovision or its Affiliates
            from licenses of the Music Protection Technology as a stand alone
            product to customers, distributors, OEM partners or other third
            parties.

            (b) Delayed Commercial Launch. In the event that the Commercial
            Launch (as defined below) has not been achieved on or before
            September 30, 2000, then, beginning October 1, 2000 and for the
            remaining term of


                                       7
<PAGE>

            this Agreement, the royalty rate percentage payable by Macrovision
            to TTR as described above shall be reduced to twenty five percent
            (25%) of Net Revenues. "Commercial Launch" shall mean the date by
            which the first of the following two events have occurred: (i) three
            of the five major music labels (Warner, Sony, BMG, EMI, Universal,
            or any of their majority owned subsidiaries) have each manufactured
            at least five million (5,000,000) music CDs which have been copy
            protected using the Music Protection Technology, or (ii) one of the
            five major music labels (Warner, Sony, BMG, EMI, Universal, or any
            of their majority owned subsidiaries) has manufactured at least five
            million (5,000,000) music CDs which have been copy protected using
            the Music Protection Technology and an aggregate total of twenty
            five million (25,000,000) (including such 5,000,000) such
            copy-protected music CDs (including such copy-protected music CDs
            manufactured by such major music label) have been manufactured.

            (c) Bundling. If Macrovision licenses the Music Protection
            Technology as a portion of another product or service it offers to
            its customers, distributors, OEM partners, or sublicensees, TTR will
            negotiate with Macrovision in good faith the allocation of revenue
            to the Music Protection Technology. Macrovision agrees that it shall
            not license the Music Protection Technology as a portion of another
            product or service until the allocation of revenue to the Music
            Protection Technology has been mutually agreed by Macrovision and
            TTR.
            (d) Payment Terms. Macrovision agrees to pay to TTR the royalties
            described in Section 5.1 on the last day of each calendar month
            during the term of this Agreement with respect to cash receipts
            actually received in the immediately preceding month. Each
            remittance to TTR hereunder shall be accompanied by a written
            report, signed by an authorized officer of Macrovision, setting
            forth in reasonable detail the basis for the determination of such
            royalty then due to TTR, including the amount of gross revenues
            received by Macrovision in respect of such preceding month.

      5.2   Minimum Royalty

            (a) Generally. In order to maintain exclusivity with respect to the
            rights granted to Macrovision by TTR hereunder, Macrovision shall
            pay to TTR, beginning twelve months following the Commercial Launch,
            a series of minimum annual guaranteed royalty advances (each a
            "Guaranteed Royalty"), recoupable dollar-for-dollar against
            royalties actually earned by TTR as its share of Net Revenues
            generated from the Music Protection Technology subsequent to


                                       8

            the payment by Macrovision of each Guaranteed Royalty during the

<PAGE>

The first such Guaranteed Royalty payment in the amount of US$1,000,000 as
provided above shall not be reduced by royalties paid pursuant to Section 5.1
hereunder during the first twelve months following Commercial Launch. Subsequent
Guaranteed Royalty payments shall not be reduced by royalties paid prior to the
payment of each such Guaranteed Royalty payment.

Notwithstanding the above, all Guaranteed Royalty payments shall be fully
creditable against all royalties payable by Macrovision to TTR as described in
Section 5.1 hereof during the term of this Agreement, which are incurred
subsequent to the payment of each such Guaranteed Royalty payment.

Except in the event of an early termination of this Agreement as described in
Section 8.2 or 8.3 hereof, all Guaranteed Royalty payments which have not
otherwise been paid to TTR as of December 31, 2009 shall be paid to TTR by
Macrovision on or before December 31, 2009.

In the event of an early termination of this Agreement as described in Section
8.2 or 8.3 hereof, all Guaranteed Royalty payments which are due but unpaid as
of the date of such early termination shall be payable by Macrovision to TTR and
all previously paid Guaranteed Royalty payments shall vest entirely in TTR.

            (b) Waived Minimum Royalty. Notwithstanding the above, if the
            Commercial Launch is achieved prior to April 30, 2000, or if the
            Commercial Launch is not achieved by September 30, 2000, then all
            Guaranteed Royalty payments described in Section 5.2(a) shall be
            waived. In the event that the Guaranteed Royalty described in
            Section 5.2(a) is waived as described in this Section and
            Macrovision shall not have paid to TTR a minimum of US$2 Million in
            aggregate royalties as provided in Section 5.1 by the second
            anniversary of the Commercial Launch, then, at Macrovision's option:
            (i) Macrovision may pay TTR any shortfall in the minimum royalty set
            forth in this paragraph within thirty days, or (ii)] Macrovision's
            exclusive license hereunder shall revert to nonexclusive status.

      5.3 Royalties for SafeDisc Technology. Macrovision shall pay to TTR, for
      the five year period beginning January 1, 2000, and ending December 31,
      2004, a royalty equal to five percent (5%) of the SafeDisc Net Revenues
      Macrovision receives from licenses of the SafeDisc technology described in
      Exhibit E ("Safe Disc Technology") to customers, distributors, or other
      third parties located in the People's Republic of China ("PRC"). The
      rights of Intercontinental Communications Center 31, Bei San Huan Zhong
      Lu, Beijing P.R.C. 100088 (aka "CICC") shall be honored by Macrovision
      through October 15, 2001, or, if earlier, the end of the term of such
      license. Notwithstanding the above, TTR and


                                       10
<PAGE>

      Macrovision will work cooperatively to transition CICC to a SafeDisc
      license as soon as possible. For purposes of this Section "SafeDisc Net
      Revenues" shall mean the gross revenues received by or on behalf of
      Macrovision or any of its Affiliates from customers, distributors, OEM
      partners or other sublicensees utilizing the SafeDisc Technology in the
      PRC, reduced by discounts, returns and rebates but not by cost of goods
      sold.

      Macrovision will pay to TTR the royalties described in this Section 5.3 on
      the last day of each calendar month during the term of this Agreement with
      respect to cash receipts actually received in the immediately preceding
      month. Each remittance to TTR hereunder shall be accompanied by a written
      report, signed by an authorized officer of Macrovision, setting forth in
      reasonable detail the basis for the determination of such royalty then due
      to TTR, including the amount of gross revenues received by Macrovision in
      respect of such immediate preceding month and reflecting a schedule of the
      customers and amounts from whom such gross revenues were collected.

      5.4 Reports. Macrovision agrees to provide reports to TTR on a quarterly
      basis (for quarters ending March 31, June 30, September 30, and December
      31 each year during the term of this Agreement), setting forth the total
      number of music CDs then manufactured to which Macrovision is aware that
      the Music Protection Technology has been applied, each such report shall
      be delivered to TTR within 45 days following the end of each such quarter
      after the Commercial Launch has occurred.

      5.5 Audit. Each of TTR and Macrovision will have the right, no more than
      once yearly, during the term of this Agreement and for one (1) year
      thereafter to have an independent "Big 5" certified public accounting firm
      (i.e., Deloitte and Touche, Arthur Andersen, Price Waterhouse Coopers,
      KPMG Peat Marwick, or Ernst & Young) review or audit the other Party's
      relevant records for the purpose of certifying compliance with this
      Agreement. All audits will be at the auditing Party's expense and
      conducted during regular business hours, and begun upon at least one (1)
      month's prior written notice. If any audit reveals a net underpayment of
      more than one percent (1%), the audited Party shall immediately pay such
      underpayment; if any audit reveals a net underpayment of more than five
      percent (5%), the audited Party shall pay the costs of the audit and
      auditing Party may conduct a follow up audit at any time upon thirty (30)
      days prior written notice, not more often than quarterly, and the audited
      Party shall pay interest on such underpayment at the prime rate then most
      recently published by the largest bank in New York (in terms of Assets)
      plus one (1) point. Finally, if three (3) audits in any three (3) year
      period reveal that an audited Party under reported, for whatever reason,
      payments by more than fifteen percent (15%), the auditing Party may


                                       11
<PAGE>

      terminate this Agreement upon ninety (90) days prior written notice to the
      audited Party.

the Music Protection Technology consistent with Macrovision's good faith
determination of the commercial potential of the Music Protection Technology.
Macrovision shall, in its sole discretion, determine the naming, branding, and

the mention of TTR described in subsection (i) and (ii) of this Section 6.1.

      6.2 Cooperative Marketing and Development Payments. Subject to the terms
of this Agreement, TTR recognizes the unique one-time costs which will be
incurred by Macrovision to co-develop and launch the Music Protection Technology
into the commercial market and agrees to reimburse Macrovision for its staffing
and other costs related to development and testing, product management, sales,
product naming/branding, marketing, and promotional expenses incurred by
Macrovision with respect to the Music Protection Technology during the twelve

      13.2 Arbitration. Any dispute, controversy or claim arising out of or
      relating to the validity, construction, enforceability or performance of
      this Agreement, including disputes relating to alleged breach or to
      termination of this Agreement, shall be settled by final, binding
      arbitration in the manner described in this Section. The arbitration shall
      be conducted pursuant to the Commercial Arbitration Rules of the American
      Arbitration Association then in effect ("Rules"). Notwithstanding the
      Rules, the following provisions shall apply to the arbitration hereunder:

            (a) Arbitrators. The arbitration shall be conducted in San
            Francisco, California by a panel of three (3) arbitrators (the
            "Panel"). Each Party shall have the right to appoint one (1) member
            of the Panel, with the third member to be mutually agreed by the
            Parties and, failing such agreement by the Parties, by the two (2)
            Panel members appointed by the Parties or appointed in accordance
            with the Rules. The arbitrators shall be persons in the industry
            with experience in the matters in dispute.

            (b) Proceedings. The Panel shall, in rendering its decision, apply
            the law of the State of California, without regard to its conflict
            of laws provisions, except that the interpretation of and
            enforcement of this Section shall be governed by the U.S. Federal
            Arbitration Act. The fees of the Panel shall be paid by the losing
            Party, which Party shall be designated by the Panel. If the Panel is
            unable to designate a losing Party, it shall so state and the fees
            shall be shared equally between the Parties.

            (c) Injunctive Relief. Each Party agrees that any violation or
            threat of violation by it or its employees of its obligations under
            this Agreement


                                       16
<PAGE>

            will result in irreparable harm to the other for which damages would
            not be an adequate remedy and, therefore, in addition to its rights
            and remedies otherwise available at law, including without
            limitation the recovery of damages for breach of such sections of
            this Agreement, the injured Party will be entitled to seek immediate
            equitable relief, including both interim and permanent injunctions,
            without the necessity of posting a bond or any other undertaking,
            and to such other and further equitable relief as the court may deem
            proper under the circumstances.

      13.3 Assignment. TTR shall not assign its rights or delegate its
      obligations hereunder without the express written consent of Macrovision ,
      which consent shall not be unreasonably withheld. Any assignment or
      delegation by TTR in violation of this Section will be void. Subject to
      the foregoing, this Agreement will benefit and bind the successors and
      permitted assigns of the Parties. Notwithstanding the foregoing, (i)
      either of Macrovision or TTR may assign this Agreement without the other's
      consent if such assignment arises out of a corporate reorganization, or
      merger, acquisition of sale in which all or substantially all of
      Macrovision's or TTR's stock or assets, as the case may be, are
      transferred to the assignee, and (ii) Macrovision may assign this
      Agreement without TTR's consent to any third party of Macrovision's
      choosing so long as Macrovision can demonstrate to TTR using commercially
      reasonable criteria that the assignee is at least as capable financially
      and operationally of fulfilling Macrovision's obligations hereunder..

      13.4 Compliance with Laws. The Parties shall comply with all laws and
      regulations applicable to its activities under this Agreement in all
      material respects. Without limiting the foregoing, the Parties shall: (i)
      comply with all United States Department of Commerce and other United
      States export controls with respect to the subject matter hereof; and (ii)
      not produce or distribute any software, products, or technical data in any
      country where such production or distribution would be unlawful.

      13.5 Entire Agreement. This Agreement, together with the Stock Purchase
      Agreement of even date herewith, including all exhibits hereto,
      constitutes the entire agreement between the Parties with respect to the
      subject matter hereof, and supersedes and replaces all prior or
      contemporaneous communications, negotiations, and agreements, written or
      oral (including the Letter Agreement)], regarding such subject matter.

THIS STOCK PURCHASE AGREEMENT, effective as of January 10, 2000, is by and
between TTR TECHNOLOGIES, INC., a Delaware corporation (the "Company"), and
MACROVISION CORPORATION, a Delaware corporation (the "Investor").

      THE PARTIES HEREBY AGREE AS FOLLOWS:

      1.    PURCHASE AND SALE OF STOCK

            1.1 Sale and Issuance of Common Stock. Subject to the terms and
            conditions of this Agreement, the Investor agrees to purchase at the
            Closing and the Company agrees to sell and issue to the Investor at
            the Closing, one million, eight hundred eighty thousand, nine
            hundred thirty- seven shares (1,880,937) of the Company's Common
            Stock $0.001 par value (the "Shares"). The purchase price for the
            Shares (subject to adjustment as provided in section 4.8 hereof)
            shall be Two Dollars and Thirteen Cents ($2.1266) per Share, or an
            aggregate purchase price of Four Million Dollars ($4,000,000) (the
            "Purchase Price"), which purchase price assumes that such Shares
            will be registered under the Securities Act within 90 days of the
            Closing and will be freely tradable as of that time by Investor,
            without regard to exemptions under the Securities Act. The per share
            Purchase Price of each Share shall be determined by dividing the
            number of shares of Common Stock outstanding immediately prior to
            the Closing, on a fully diluted basis, into $31 million. The number
            of Shares of Common Stock to be issued to Investor shall be
            determined by dividing the per share Purchase Price, determined in
            the preceding sentence, into the aggregate $4 million Purchase
            Price.

            1.2 Closing. The purchase and sale of the Common Stock shall take
            place at the offices of Manatt, Phelps & Phillips LLP, 3030 Hansen
            Way, Suite 100, Palo Alto, California (or such other location as the
            Investor may designate and the Company consents thereto), at 10:00
            A.M. on January 12, 2000, or such other time and date as the
            Investor determines that all of the conditions to the obligation of
            Investor, set forth in Section 5 hereof, have been or will be
            satisfied (the "Closing"). At the Closing, the Company shall deliver
            to the Investor a certificate representing the Shares against
            receipt by the Company from the Investor of a wire transfer in the
            amount of the Purchase Price.

      forth on a Schedule of Exceptions attached as Schedule A hereto (the
      "Schedule of Exceptions"), specifically identifying the relevant
      subparagraph hereof, which exceptions shall be deemed to be a part of the

                  of any shares of its capital stock or any future issuance of
                  securities by the Company.

                  (iv) Voting Agreements. Except as set forth in this Agreement,
                  the Company has no agreement, obligation or commitment with
                  respect to the election of any individual or individuals to
                  the Board, and to the best of the Company's knowledge, there

            with all applicable laws, rules, regulations, judgments, decrees and
            governmental orders, except for such non-compliance that would not

            condition, operations, prospects or business of the Company. The
            Company has received no notice of any violation of such laws, rules,
            regulations, judgments, decrees or orders which has not been
            remedied prior to the date hereof or which would have a Material
            Adverse Effect on the Company. The execution, delivery and
            performance of the Agreement and the consummation of the
            transactions contemplated thereby will not result in any such
            violation or default, or be in conflict with or constitute, with or
            without the passage of time or the giving of notice or both, either
            a default under the Company's Certificate of Incorporation or
            Bylaws, both as currently in effect, or an event which results in
            the creation of any material lien, charge or encumbrance upon


                                       3
<PAGE>

            the capital stock or any asset of the Company, or a default under
            any Material Agreement or contract by the Company, or a violation of
            any laws, rules, regulations, judgments, decrees or orders. All
            material licenses, permits, approvals, registrations,
            qualifications, certificates and other authorizations necessary for
            the conduct of the Company's business as presently conducted (the
            "Licenses") have been duly obtained and are in full force and
            effect, and there are no proceedings pending or threatened which may
            result in the revocation, cancellation, suspension or any material
            adverse modification of any of such Licenses, except for Licenses
            that, individually or in the aggregate, the Company need not hold or
            possess in order to avoid a Material Adverse Effect on the Company's
            assets, properties, financial condition, operating results or
            business. The Company believes it can obtain, without undue burden
            or expense, any similar authority for the conduct of its business in
            the future as presently conducted and proposed to be conducted.

            2.7 Compliance with Other Instruments, None Burdensome, Etc. The
            execution, delivery and performance of and compliance with this
            Agreement and the issuance and sale of the Shares will not result in
            nor constitute any breach, default or violation of (i) any
            agreement, contract, lease, license, instrument or commitment (oral
            or written) to which the Company is a party or is bound and which
            involves payment by the Company or any of its subsidiaries in excess
            of $250,000 or which is otherwise material to the business,
            properties, financial condition or results of operation of the
            Company or its subsidiaries (a "Material Agreement") or (ii) any
            law, rule, regulation, statute or order applicable to the Company,
            any of its subsidiaries or their respective properties, nor result
            in the creation of any mortgage, pledge, lien, encumbrance or charge
            upon any of the properties or assets of the Company or its
            subsidiaries.

            2.8 Government Consent, Etc. No consent, approval, order or
            authorization of, or designation, registration, declaration or
            filing with, any federal, state, local or provincial or other
            governmental authority on the part of the Company is required in
            connection with the valid execution and delivery of this Agreement
            or the consummation of the transactions contemplated herein,
            including the offer, sale or issuance of the Shares to the Investor.

            2.9 Offering. In reliance on the representations and warranties of
            Investor in Section 3, hereof, the offer, sale and issuance of the
            Shares will not, to the best knowledge of the Company, result in a
            violation of the requirements of Section 5 of the Securities Act or
            the qualification or registration requirements of the California or
            other applicable blue sky laws or foreign laws as such laws exist on
            the date hereof. 2.10 Litigation. There is no action, suit,
            proceeding or investigation pending or currently threatened against
            the Company which questions the


                                       4
<PAGE>

            validity of this Agreement or the consummation of the transactions
            contemplated hereby or which might result, either individually or in
            the aggregate, in any Material Adverse Effects on the assets,
            financial condition, operations or business of the Company,
            financially or otherwise, or any change in the current equity
            ownership of the Company. The Company is not a party or subject to
            the provisions of any order, writ, injunction, judgment or decree of
            any court or government agency or instrumentality. There is no
            action, suit, proceeding or investigation by the Company currently
            pending or which the Company currently intends to initiate.

                  or guarantee credit) to any of them.

                  (ii) To the best of the Company's knowledge, no employee or
                  officer has any direct or indirect ownership interest in any
                  firm or corporation with which the Company is affiliated or
                  with which the Company has a business relationship, or any
                  firm or corporation that competes with the Company, except
                  that employees or officers of the Company and members of their
                  immediate families may own stock in publicly traded companies
                  that may compete with the Company. Prior to the Closing, no
                  officer, director or major


                                       5
<PAGE>

                  shareholder or member of the immediate family of any officer,

                  indirect financial interest in any material contract with the
                  Company.

            2.13 Environmental and Safety Laws. To the best of its knowledge,
            the Company is not in violation of any applicable statute, law, or
            regulation relating to the environment or occupational health and
            safety, and to the best of its knowledge, no material expenditures
            are or will be required to comply with any such existing statute,
            law, or regulation.

            2.14 Status of Proprietary Assets.

                  (i) Ownership. The Company owns, is licensed to use or
                  otherwise has the right to use all patents, trademarks,
                  service marks, trade names, copyrights and trade secrets that
                  are material or necessary for the operation of its business as
                  now conducted (the "Proprietary Assets"). The Company has not
                  received within the past 36 months preceding the date first
                  set out above any communications alleging that the Company has
                  violated or, by conducting its business, would violate any of
                  the patents, trademarks, service marks, trade names,
                  copyrights, trade secrets or other proprietary rights or
                  processes of any other person or entity. The Company has not
                  granted any license or option or entered into any agreement of
                  any kind with respect to the use of the Proprietary Assets
                  owned by it, other than licenses to and sales of its products
                  and services made in the ordinary course of its business.

                  (ii) Licenses; Other Agreements. The Company is not bound by
                  or a party to any option, license or agreement with respect to
                  any technology owned by any third party other than shrink-wrap
                  licenses entered into in the ordinary course of business
                  except as set forth on the Schedule of Exceptions. The Company
                  is not obligated to pay any royalties or other payments to
                  another person or entity with respect to the marketing, sale,
                  distribution, manufacture, license or use of any Proprietary
                  Asset or any other property or rights, except as set forth in
                  the Schedule of Exceptions.

                  (iii) No Breach by Employees. To the best of the Company's
                  knowledge, no employee of the Company is subject to any
                  judgment, decree or order of any court or administrative
                  agency, or any other restriction that would materially
                  interfere with the use of his or her best efforts to carry out
                  his or her duties for the Company or that would conflict with
                  the Company's business as currently conducted. The Company has
                  received no written notice from any former employer that any
                  employee of the Company has


                                       6
<PAGE>

                  prior obligations to a former employer that would interfere or
                  conflict with such employee's ability to perform his or her
                  intended services for the Company. To the best of the
                  Company's knowledge and belief, no employee or advisor of the
                  Company is or is now expected to be in violation of any term
                  of any employment contract, patent disclosure agreement,
                  proprietary information and inventions agreement or any other
                  contract or agreement or any restrictive covenant or any other
                  common law obligation to a former employer relating to the
                  right of any such employee to be employed by the Company
                  because of the nature of the business conducted by the Company
                  or to the use of trade secrets or proprietary information of
                  others, and the employment of the Company's employees does not
                  subject the Company to any liability, except where such
                  liability would not have a material adverse effect. There is
                  neither pending nor, to the Company's knowledge and belief,
                  threatened any actions, suits, proceedings or claims, or to
                  its knowledge any basis therefor or threat thereof with
                  respect to any contract, agreement, covenant or obligation
                  referred to in the preceding sentence.

                  (iv) No Infringement. Within the 36 months preceding the date
                  first set out above, no claims with respect to the Proprietary
                  Assets have been communicated to the Company: (A) to the
                  effect that the manufacture, sale, license or use of any
                  Proprietary Asset as now used or offered or proposed for use
                  or sale by the Company infringes any copyright, patent, trade
                  secret or other intellectual property right of a third party,
                  or (B) challenging the ownership or validity of any of the
                  Company's rights to or interest in such Proprietary Assets.
                  The Company has received no notice to the effect that any
                  patents or registered trademarks, service marks or registered
                  copyright, held by the Company are invalid or not subsisting
                  except for failures to be valid and subsisting that would not
                  reasonably be expected to have, individually or in the
                  aggregate, a Material Adverse Effect on the Company. To the
                  best of the Company's knowledge, there has been no material
                  unauthorized use, infringement or misappropriation of any of
                  the Proprietary Assets by any third party, including any
                  employee or former employee of the Company.

            2.15 Material Agreements. The Company has not breached in any
            material respect any term or condition of (A) any Material Agreement
            or (B) any other agreement, contract, lease, license, instrument or
            commitment (oral or written) that, individually or in the aggregate,
            would have a Material Adverse Effect on the properties, financial
            condition, operating results, prospects or business of the Company.
            The Company is


                                       7
<PAGE>

            not a party to any agreement that restricts in any material respect
            its ability to market, sell or license any of its products or
            services (whether by territorial restriction or otherwise).

            2.16 Disclosure. The Company has fully provided the Investor with
            all information which the Investor has requested for deciding
            whether to purchase the Shares and the Company is not aware of any
            material information which it has not provided to the Investor and
            which the Company believes is reasonably necessary to enable the
            Investor to decide whether to enter into the transaction
            contemplated by this Agreement. Neither this Agreement nor any other
            certificate made or delivered in connection with this Agreement and
            the transactions contemplated hereby contains any untrue statement
            of a material fact or omits to state a material fact necessary not
            to make the statements herein or therein misleading. 2.17
            Registration Rights. The Company has not granted or agreed to grant
            to any person or entity any rights (including piggyback registration
            rights) to have any securities of the Company registered with the US
            Securities and Exchange Commission ("SEC") or any other governmental
            authority.

            2.18 Tax Status. The Company has made or filed all federal, state
            and foreign income and all other tax returns, reports and
            declarations required by any jurisdiction to which it is subject and
            has paid all taxes and other governmental assessments and charges
            that are shown to be due on such returns, reports and declarations
            or otherwise due, except those being contested in good faith, and
            has set aside on its books provisions reasonably adequate for the
            payment of all taxes for periods subsequent to the periods to which
            such returns, reports or declarations apply. To the knowledge of the
            Company, there are no unpaid taxes in any material amount claimed to
            be due by the taxing authority of any jurisdiction, and the officers
            of the Company know of no basis for any such claim. The Company has
            not executed a waiver with respect to the statute of limitations
            relating to the assessment or collection of any foreign, federal,
            state or local tax. None of the Company's tax returns is presently
            being audited by any taxing authority.

            2.19  Employees.

                  (i) Employee Benefit Plans. The Company does not have any
                  Employee Benefit Plan as defined in the Employee Retirement
                  Income Security Act of 1974.

                  (ii) Labor Agreements and Actions. The Company is not bound by
                  or subject to (and none of its assets or properties is bound
                  by or subject to) any written or oral, express or implied,
                  contract, commitment or arrangement with any labor union, and
                  no labor union has requested or to the knowledge of the
                  Company, has sought to represent any of the employees,
                  representatives or agents


                                       8
<PAGE>

                  of the Company. There is no strike or other labor dispute
                  involving the Company pending, or to the knowledge of the
                  Company threatened, which could have a Material Adverse Effect
                  on the assets, properties, financial condition, operation or
                  business of the Company, nor is the Company aware of any labor
                  organization activity involving its employees. The employment
                  of each officer and employee of the Company is terminable at
                  the will of the Company upon the giving of notice and the
                  payment of specified amounts. Company has complied in all
                  material respects with all applicable state and federal equal
                  employment opportunity laws and with other laws related to
                  employment.

                  (iii) Confidential Information and Invention Assignment
                  Agreements. Each management and technology employee,
                  consultant and officer of the Company has executed an
                  agreement with the Company regarding confidentiality and
                  proprietary information. The Company is not aware that any of
                  its employees or consultants is in violation thereof, and the
                  Company will use its best efforts to prevent any such
                  violation.

            2.20 Insurance. The Company maintains and keeps in force with good
            and responsible insurance companies fire, public liability, property
            damage and other insurance, of the kinds and in amounts as are usual
            and customary in the type of business conducted by the Company.

            2.21 Title to Property and Assets. The Company owns and has valid
            title to its property and assets free and clear of all mortgages,
            liens, loans and encumbrances, except such encumbrances and liens
            which arise in the ordinary course of business and do not materially
            impair the Company's ownership or use of such property or assets or
            which would not, in the aggregate, have a Material Adverse Effect.
            With respect to the property and assets it leases, the Company is in
            compliance with such leases and, to the best of its knowledge, holds
            a valid leasehold interest free of any liens, claims or
            encumbrances. The Company does not own any real property.

            2.22 Financial Statements. The Company shall deliver to Investor, on
            or before January 10, 2000, the Company's annual financial
            statements (balance sheet and statement of earnings, statement of
            shareholders' equity and statement of cash flows) dated as of
            December 31, 1998 and interim financial statements for the eleven
            months of operations ended November 30, 1999 (the "Financial
            Statements"), in each case, such Financial Statements shall be
            prepared in accordance with United States generally accepted
            accounting principles ("GAAP"), shall include all footnotes in
            accordance with GAAP, and shall be audited by the Israeli office or
            affiliate of a "Big 5" public accounting firm (i.e., Deloitte and
            Touche, KPMG Peat Marwick, Price Waterhouse Coopers, Arthur Anderson

            the dates, and for the periods, indicated therein, subject to normal
            year-end adjustments. The Financial Statements described in
            subsection 2.21 hereof and the audited balance sheet as of November
            30, 1999, as adjusted by the auditor's subsequent event disclosure
            footnote, shall not show liabilities due within 18 months from the
            date thereof in an amount in excess of One Million Dollars
            ($1,000,000) over the amount of cash and cash equivalents shown on
            such balance sheet.

            2.23 Except as set forth in the Financial Statements, the Company
            has no liabilities, contingent or otherwise, other than (i)
            liabilities incurred in the ordinary course of business and (ii)
            obligations under contracts and commitments incurred in the ordinary
            course of business and not required under GAAP to be reflected in
            the Financial Statements, which, in both cases, individually or in
            the aggregate, are not material to the financial condition or
            operating results of the Company.

            2.24 SEC Documents, Financial Statements. Since November 30, 1999,
            the Company has timely filed all reports, schedules, forms,

            SEC pursuant to the reporting requirements of the Exchange Act (all
            of the foregoing filed prior to the date hereof and all exhibits
            included therein and financial statements and schedules thereto and
            documents (other than exhibits) incorporated by reference therein,
            being hereinafter referred to herein as the "SEC Documents"). The
            Company has delivered to the Investor, or the Investor has had
            access to, true and complete copies of the SEC Documents, except for
            such exhibits and incorporated documents. As of their respective
            dates, the SEC Documents complied in all material respects with the
            requirements of the Exchange Act or the Securities Act, as the case
            may be, and the rules and regulations of the SEC promulgated
            thereunder applicable to the SEC Documents, and none of the SEC
            Documents, at the time they were filed with the SEC, contained any
            untrue statement of a material fact or omitted to state a material
            fact required to be stated therein or necessary in order to make the
            statements therein, in light of the circumstances under which they
            were made, not misleading. As of their respective dates, the
            consolidated financial statements of the Company included in the SEC
            Documents complied as to form in all material respects with
            applicable accounting requirements and the published rules and
            regulations of the SEC with respect thereto. Except as disclosed in
            the SEC Documents, since November 30, 1999, there has been no
            material adverse change in the assets, liabilities, business,
            properties, operations, financial condition, or operations of the
            Company on a consolidated basis.

            2.25 No Integrated Offering. Neither the Company, nor any of its
            affiliates, nor any person acting on its or their behalf, has

<PAGE>

            indirectly made any offers or sales in any security or solicited any
            offers to buy any security under circumstances that would require
            registration under the Securities Act of the issuance of the Shares
            to the Investor. The issuance of the Shares to the Investor will not
            be integrated with any other issuance of the Company's securities
            (past, current or future) for purposes of the Securities Act.

            2.26 Year 2000. The mission critical computer software operated by
            the Company and each of its subsidiaries is currently capable of

            falling on or after January 1, 2000 in substantially the same manner
            and with the same functionality as such mission critical software
            records, stores, processes and processes and presents such calendar
            dates falling on or before December 31, 1999. The costs of the
            adaptations referred to in this clause will not have a Material
            Adverse Effect.

      3.    REPRESENTATIONS AND WARRANTIES OF THE INVESTOR.

      The Investor hereby represents and warrants that:

            3.1 Authorization. The Investor has full power and authority to
            enter into this Agreement. This Agreement constitutes a valid and
            binding obligation of the Investor enforceable against the Investor
            in accordance with its terms, except (i) as limited by applicable
            bankruptcy, insolvency, reorganization, moratorium, and other laws
            of general application affecting enforcement of creditors' rights
            generally and (ii) as limited by laws relating to the availability
            of specific performance, injunctive relief, or other equitable
            remedies.

            3.2 Purchase Entirely for Own Account. The Investor is acquiring the
            Shares for investment for its own account, not as a nominee or
            agent, and not with a view to, or for the resale or distribution of
            any part thereof. The Investor has no present intention of selling,
            granting any participation in, or otherwise distributing the same.
            The Investor further represents that it does not have any contract,
            undertaking, agreement or arrangement with any person to sell,
            transfer or grant participations to such person or to any third
            person, with respect to any of the Shares. 3.3 Disclosure of
            Information. The Investor has received all of the information which
            it considers necessary or appropriate for deciding whether to
            purchase the Shares. The Investor further represents that it has had
            an opportunity to ask questions and receive answers from the Company
            regarding the terms and conditions of the offering of the Shares.
            The foregoing, however, does not limit or modify the representations
            and warranties of the Company in Section 2 of this Agreement or the
            right of the Investor to rely thereon.

            3.4 Investment Experience. The Investor (i) fully understands that
            an investment in the Company is highly speculative and that it may
            lose its


                                       11
<PAGE>

            entire investment in the Shares purchased from the Company; (ii) is
            experienced in evaluating and investing in development stage
            companies such as the Company, (iii) is capable of evaluating the
            merits and risks of its investment in the Shares; (iv) is able to
            bear the economic risk of a loss of the entire amount of its
            investment in the Shares; and (v) is prepared to hold the Shares for
            an indefinite period of time. 3.5 Accredited Investor. The Investor
            is an "accredited investor" within the meaning of Securities and
            Exchange Commission Rule 501 of Regulation D, as presently in
            effect.

            3.6 Restricted Securities. The Investor acknowledges that, because
            the Shares have not been registered under the Securities Act, the
            Shares must be held indefinitely unless subsequently registered
            under the Securities Act or an exemption from such registration is
            available. The Investor is aware of the provisions of Rule 144
            promulgated under the Securities Act which permits limited resale of
            securities purchased in a private placement subject to the
            satisfaction of certain conditions.. 3.7 Legends. The Investor
            understands that until (a) the Shares may be sold by the Investor
            under Rule 144(k) or (b) such time as the resale of the Shares have
            been registered under the Securities Act as contemplated in Section
            4.8 hereof, the certificates representing the Shares will bear a
            restrictive legend in substantially the following form (and a
            stop-transfer order may be placed against transfer of the
            certificates for such Shares):

            THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
            REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR THE
            SECURITIES LAWS OF ANY STATE OF THE UNITED STATES. THE SECURITIES
            MAY NOT BE SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN
            EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER APPLICABLE
            SECURITIES LAWS, OR UNLESS OFFERED, SOLD OR TRANSFERRED PURSUANT TO
            AN AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENT OF THOSE
            LAWS.

      The legend set forth above will be removed and the Company will issue a
      certificate without the legend to the holder of any certificate upon which
      it is stamped, upon registration of the Shares, in accordance with the
      terms of Section 4.8 hereof.

      4.    COVENANTS AND AGREEMENTS

            4.1 Ordinary Course of Business and Notice of Adverse Changes. From
            and after the date of this Agreement through the Closing, the
            Company shall conduct its business in the ordinary course and
            consistent


                                       12
<PAGE>

            in all material respects with past practice, except as may be
            required or contemplated in this Agreement. The Company shall advise
            the Investor promptly of any Material Adverse Effect, any breach of
            the Company's representations or warranties, or any breach of a
            covenant contained herein of which the Company has knowledge.

            4.2 Access to Properties and Records. The Company shall afford to
            the Investor and its respective accountants, counsel and
            representatives, reasonable access upon notice to the Company and
            upon agreed upon times during normal business hours throughout the
            period prior to the Closing to all of the Company's properties,
            books, contracts, commitments and written records and shall make
            reasonably available its respective officers and employees to answer
            fully and promptly questions put to them (so long as such questions
            are not outside of the scope or purpose of this Section; provided
            that such access shall not unreasonably interfere with the normal
            business operations of the Company). Any such investigations shall
            be specifically related to this Agreement and to the transactions
            contemplated hereby.

            4.3 Exclusive Negotiations. Except in the furtherance of the
            transactions contemplated herein, prior to the Closing, the Company
            shall not directly, and shall use its reasonable best efforts to
            cause its respective directors, officers, employees, representatives
            or agents (including, without limitation, any investment banker,
            attorney or accountant retained by it or any of its affiliates) not
            to, directly or indirectly, initiate, solicit or encourage any
            inquiries or the making or implementation of any proposal or offer,
            with respect to any merger, acquisition, consolidation, share
            exchange, business combination or other transaction involving, or
            which would result in the acquisition of a majority of the
            outstanding equity securities or substantially all of the assets of
            the Company (any such proposal or offer being hereinafter referred
            to as an "Acquisition Proposal"), or engage in any negotiations
            concerning, or provide any confidential information or data to, any
            person or entity relating to an Acquisition Proposal, or otherwise
            facilitate any effort or attempt to make or implement an Acquisition
            Proposal. The Company shall immediately cease and cause to be
            terminated any existing activities or negotiations with any parties
            conducted heretofore with respect to any Acquisition Proposal, and
            it shall take the necessary steps to inform any such parties of the
            obligations undertaken in this Section. The Company shall notify the
            Buyer immediately if any such inquiries or proposals are received
            by, any such information is requested from, or any such negotiations
            are sought to be initiated or continued with, the Company.

            4.4 Right of First Refusal. If, during the period from the Closing
            through December 31, 2009 (and so long as the Alliance Agreement is
            in effect), the Company (or any subsidiary or affiliate) proposes
            either to sell,


                                       13
<PAGE>

            transfer or assign, directly or indirectly, securities in the
            Company or any subsidiary or affiliate thereof equal to, or
            convertible into, a majority of the outstanding Common Stock of the
            Company (a "Substantial Equity Interest"), the Investor shall have a
            first right of refusal to purchase such Substantial Equity Interest
            proposed to be sold, transferred or assigned, for a price equivalent
            to the bona fide sale or transfer price offered for such Substantial
            Equity Interest and otherwise in accordance with the terms and
            conditions of such offer. The right of first refusal granted to the
            Investor is intended to apply to any sale, transfer or assignment,
            directly or indirectly, to any nominee or straw-men, corporation or
            other entity, including the sale of stock or an interest in a
            partnership, limited-liability corporation, trust or other entity
            which holds substantially all of the assets of the Company or any of
            its subsidiaries or affiliates, if the intent of any such sale,
            transfer or assignment to such person or entity is to avoid the
            Investor's right of first refusal contained in this Section. 4.5
            Preemptive Right of Investor.

                  (i) The Company hereby grants to the Investor the preemptive
                  right to purchase its Pro Rata Share (defined below) of any
                  New Securities (defined below) that the Company intends to
                  offer for sale and issuance at the time and on the terms set
                  forth herein (the "Preemptive Right").

                        as "Options"), and those securities that are convertible
                        into or exchangeable for any such Common Stock
                        (collectively referred to as "Convertible Securities"),
                        if the gross proceeds received or receivable by the
                        Company as consideration for the issue of such Common
                        Stocks, Options or Convertible Securities, plus the
                        minimum aggregate amount of additional consideration (as
                        set forth in the instruments relating thereto, without
                        regard to any provision contained therein designated to
                        protect against dilution) payable to the Company upon
                        the exercise of such Options or the conversion or
                        exchange of such Convertible Securities, equals or
                        exceeds One Million Five Hundred Thousand Dollars

                        consultants not in excess of 1,350,000 shares,
                        representing approximately eight point two percent
                        (8.2%) of the Company's 16,458,114 aggregate issued and
                        outstanding shares of common stock post- Closing (on a
                        fully-diluted basis) by the Company; (iv) any capital
                        stock or other securities (or related options or
                        warrants) offered or issued to directors, officers or
                        employees of, or consultants to, the Company pursuant to
                        an agreement or an option or purchase plan program, or
                        any other stock incentive plan or program approved by
                        the Board of Directors of the Company; or (v) any
                        capital stock or other securities issued in connection

                        or the like by the Company.

                        (2) "Ownership Ratio" shall mean the ratio of shares of
                        Common Stock of the Company held by the Investor on the
                        day immediately preceding the date of the notice
                        described in subsection (c) below to the total number of
                        shares of Common Stock of the Company then outstanding.

                        (3) "Pro Rata Share" for purposes of the Preemptive
                        Right, shall mean all New Securities which the Company
                        intends to offer for sale multiplied by the Investor's
                        Ownership Ratio.

                  (iii) If at any time from the Closing through December 31,
                  2009, the Company plans or otherwise intends to undertake an
                  issuance of New Securities, the Company shall, so long as the
                  Alliance Agreement is in effect, give the Investor written
                  notice describing the type of New Securities, the price, and
                  the general terms upon which the Company plans or otherwise
                  intends to issue the same. The Investor shall have fifteen
                  (15) days from the date of delivery of any such notice to
                  agree to purchase all or a portion of its Pro Rata Share of

                  specified in the notice by giving written notice to the
                  Company at or before the end of such fifteen (15) days. If the
                  Investor either fails to so notify the Company or indicates
                  that it will not purchase its Pro Rata Share, the Company
                  shall thereafter be free to offer, sell and issue the New
                  Securities, including any such Pro Rata Share not purchased by
                  the Investor, to any third


                                       15

                  party so long as such sale is at a price and is upon general
                  terms no more favorable than described in the Company's
                  notice.

            4.6 Certain Employment Matters. Effective as of the date of the
            Closing, there are no employment agreements to which the Company is
            a party other than those set out in the tabled attached as Schedule
            4.6 hereto.

            4.7 Board Observer. The Company hereby covenants and agrees with
            Investor that, as long as the Alliance Agreement (defined below)
            remains in effect, the Investor shall have the right to designate a

            that the same prior notice given to the Board of Directors shall be

            Company's By-laws for notices to directors of the time and place of
            any proposed meeting of the Board of Directors, such notice in all
            cases to include true and complete copies of all documents furnished
            to any director in connection with such meeting. Such Observer will
            be entitled to be present in person as an observer at any such

            appropriate form) covering the Shares (the "Registration Statement")
            and shall use its best efforts to cause such registration statement
            to be declared effective within 90 days following the Closing. The
            Company further covenants and agrees to maintain the Registration
            Statement Effective for one year following the effective date of the
            Registration Statement, provided, that, 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 Shares, or engage
            in any other transaction involving or relating to the Shares, 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 such right to
            the Investor during the period the Registration Statement is
            required to be in effect for more than 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. As used herein,
            "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. In the event that the
            Registration Statement is not declared effective within 90 days
            following Closing, then the Company shall issue to the Investor, in
            respect of each full calendar week (beginning on Monday) following
            such 90th day and continuing until such time as the Registration
            Statement shall have been declared effective, such number of shares
            of Common Stock as shall be equal to one and one quarter percent (1
            1/4%) of the number of Shares issued hereunder (the "Additional
            Shares"), provided, that, notwithstanding anything to the contrary
            contained in the foregoing, the Company shall have no obligation to
            issue any Additional Shares in excess of such number of Additional
            Shares as shall be equal to, in the aggregate, 10% of the number of
            Shares issued hereunder. Reporting Status; Eligibility to Use Form
            S-1. The Company's Common Stock is registered under Section 12 of
            the Exchange Act. The Company will file with the SEC a Current
            Report on Form 8-K disclosing this Agreement and the transactions
            contemplated hereby within 10 business days after the Closing.
            Throughout the one year registration period (referred to in Section
            4.8 hereof), the Company shall to file all reports, schedules,
            forms, statements and other documents required to be filed by it
            timely with the SEC under the reporting requirements of the Exchange
            Act, and the Company will not terminate its status as an issuer
            required to file reports under the Exchange Act even if the Exchange
            Act or the rules and regulations thereunder would permit such
            termination. The Company currently meets, and will take all
            reasonably necessary action to continue to meet, the "registrant
            eligibility" requirements set forth in the general instructions to
