                               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.

      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
the five years ended December 31, 1999. The selected consolidated financial data
for the years ended December 31, 1997, 1998 and 1999 are derived from our
consolidated financial statements for such years, which have been audited by
Brightman Almagor & Co., a member of Deloitte Touch Tohmatsu, independent
auditors. The selected consolidated financial data for the years ended December
31, 1995 and 1996 are derived from our consolidated financial statements for
such period and years, which have been audited by Schneider Ehrlich & Associates
LLP (formerly known as Schneider Ehrlich & Wengrover LLP), independent auditors.
The consolidated financial data set forth below should be read in conjunction

                     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
<PAGE>

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
<PAGE>

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
<PAGE>

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

      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


                                       29

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

      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

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,

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

*     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.

                            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

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
member of Deloitte Touche Tohmatsu, also states that substantial doubt exists
regarding our ability to continue as a going concern.

                         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.

      (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.

            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.

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.
      123. Had compensation cost for all of the Company's stock-based
      compensation grants been determined in a manner consistent with the fair
      value approach described in SFAS No. 123, the Company's net loss and net
      loss per share as reported would have been increased to the pro forma

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.

      exhibit.

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.

pursuant to the terms of this Subsection 1.1, to receive Shares equal to the
value of this Warrant (taking into account only that portion of this Warrant
that is then exercisable) by surrender of this Warrant at the principal office
of the Company together with notice of such election in which event the Company
shall issue to the Holder a number of Shares using the following formula:

                                  X = Y(A-B)
                                      ------
                                        A

where X = The number of Shares to be issued to the Holder.

      Y = The number of Shares purchasable under this Warrant (at the date of
such calculation).

      A = The fair market value of one Share (at the date of such calculation).

      B = The Per Share Warrant Purchase Price.

2. Representations and Warranties

      The Holder (i) represents, warrants, covenants and agrees that the Warrant
and the underlying Warrant Shares are being acquired by the Holder for the
Holder's own account, for investment purposes only, and not with a view to or
for the sale in connection with any distribution thereof or with any present
intention of selling or distributing all or any part of the Warrant or the


                                        2
<PAGE>

Warrant Shares; (ii) understands (x) that if it should thereafter decide to
dispose of such Warrant or Warrant Shares (which it does not contemplate at such
time) it may do so only in compliance with the Securities Act, (y) this Warrant
and the Warrant Shares are not registered under the Securities Act; and (iii)
acknowledges that, as of the date hereof, it has been given a full opportunity
to ask questions of and to receive answers from the Company concerning this
Warrant and the Warrant Shares and the business of the Company and to obtain
such information as it desired in order to evaluate the acquisition of this
Warrant and the Warrant Shares, and all questions have been answered to its full
satisfaction.

3. Reservation of Shares

      The Company covenants that at all times during the Warrant Period it shall
have authorized and in reserve, and will keep available solely for issuance or
delivery upon exercise of the Warrant, the Warrant Shares and other securities
and properties as from time to time shall be receivable upon the exercise of
this Warrant, free and clear of preemptive rights and restrictions on sale or
transfer except as otherwise set forth herein or in the By-Laws.

4. Registration Rights

      The Holder acknowledges that there exists an effective Company
registration statement filed under the Securities Act on or about October 4,
1999 [Registration No. 333-85085] (the "Filed Registration Statement"), which
Filed Registration Statement inludes certain securities (other than the Warrant
Shares) held by the Holder. The Holder further acknowledges that the Filed
Registration Statement was filed pursuant to the terms of a Registration Rights
Agreement, dated as May 13, 1999, between the Company and the Initial Investors
named therein (the "Initial Investors"). The Company will explore the option of
amending the Filed Registration Statement to include the Warrant Shares, subject
to the Holder executing a lock-up agreement in substantailly the same form as
previously signed by Biscount.

      In the event that the Company does not for whatever reason amend the Filed
Registation Statement to include the Warrant Shares, then if the Company shall
file a registration statement for any shares of its Common Stock, it shall
include in the registration statement relating thereto the Warrant Shares,
except that where such registration statement was filed on behalf of a
shareholder or a rights holder, such inclusion shall be with the consent of such
shareholder or rightsholder. In the event that such registration offering
involves an underwriting, the rights of the Holder to have the Warrant Shares
included in such registration statement shall be conditional upon the
underwriter's determination as to the marketing factors requiring limitation of
such right, and the underwriter may preclude any or all securities of the Holder
which could have otherwise been included in such offering.

5. Adjustment

<PAGE>

      5.1 In case prior to the expiration of this Warrant by exercise or by its
terms the Company shall issue any shares of its Common Stock as a stock dividend
or subdivide the number of outstanding shares of Common Stock into a greater
number of shares by a stock split or a similar transaction, then, in either of
such cases, the Exercise Price per share of the Warrant Shares purchasable
pursuant to this Warrant in effect at the time of such action shall be
proportionately reduced and the number of Warrant Shares purchasable at that
time shall be proportionately increased; and, conversely, in the event the
Company shall contract the number of outstanding shares of Common Stock by
combining such shares into a smaller number of shares by a reverse split or
similar transaction, then, in such case, the Exercise Price per share of the
Warrant Shares purchasable pursuant to this Warrant shall be proportionately
increased and the number of Warrant Shares purchaseable at that time shall be
propotionately reduced. Any dividend paid or distributed upon the Common Stock
in stock of any other class of securities convertible into shares of Common
Stock shall be treated as a dividend paid in Common Stock to the extent that
shares of Common Stock are issuable upon conversion thereof.

      5.2 In case of any consolidation or merger of the Company with or into
another corporation (other than a merger or consolidation in which the Company
is the surviving or the continuing corporation) or in the case of any sale or
conveyance to another corporation or other entity of the property, assets or
business of the Company as an entirety or substantially as an entirety, in any
such case, the Company or such successor or purchasing corporation or entity, as
the case may be, shall (i) execute with the Holder an agreement that the Holder
shall have the right thereafter to receive upon the exercise of the Warrant the
kind and amount of shares and/or other securities or other property which he
would have owned or have been entitled to receive after the happening of such
consolidation, merger, sale or conveyance had the Warrant been exercised
immediately prior to such action, (ii) make effective provision in its
certificate of its incorporation or otherwise, if necessary, in order to effect
such agreement, and (iii) set aside or reserve for the benefit of the Holder,
the stock, securities, property and cash to which the Holder would be entitled
to upon exercise of this Warrant.

      5.3 In case of any reclassification or change of the Warrant Shares
issuable upon exercise of this Warrant (other than a change in par value or from
no par value to a specific par value, or as a result of a subdivision or
combination, including any change in the shares into two or more classes or
series of shares), or in the case of any consolidation or merger of another
corporation into the Company in which the Company is the continuing corporation
and in which there is a reclassification or change (including a change in the
right to receive cash or other property) of the Shares (other than a change in
the par value, or from no par value to a specific par value or, as a result of a
subdivision or combination, including any change in the shares into two or more
classes or series of shares), Holder shall have the right thereafter to receive
upon exercise of this Warrant solely the kind and amount of shares of stock and
other securities, property, cash or combination thereof receivable upon such
reclassification, change, consolidation or merger by a holder of the number of
Shares for which this Warrant might have been exercised immediately prior to
such reclassification, change, consolidation or merger.

successive reclassifications and changes of Shares and to successive
consolidations, sales, leases or conveyances.

6. Limited Transfer

      (a) This Warrant may not be sold, transferred, assigned or hypothecated by
the Holder except in a transation exempt from registration under the Securities
Act and any applicable state securities laws, and is so transferable only on the
books of the Company which the Company shall cause to be maintained for such
purpose. The Company may treat the registered holder of record as the Holder for
all purposes. The Company may require the Holder to provide the Company with an
opinion of counsel in substance reasonably satisfactory to it or to its counsel
as to such exemption. The Company shall permit any holder of a Warrant or his
duly authorized attorney, upon written request during ordinary business hours,
to inspect and copy or make extracts from its books showing the registered
holders of Warrants.

      (b) In no event shall the Company be obligated to effect any transfer of
Warrants or Warrant Shares unless a registration statement is in effect with
respect thereto under applicable state and Federal securities laws or unless the
Company has received an opinion in substance reasonably satisfactory to it from
counsel that such registration is not required. Unless registered, the Warrant
Shares issued upon exercise of the Warrants shall be subject to a stop transfer
order and the certificate or certificates evidencing such Warrant Shares shall
bear the following legend:

"THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED, PURSUANT TO A REGISTRATION STATEMENT.
ACCORDINGLY, SUCH SHARES MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO A
REGISTRATION STATEMENT UNDER SUCH ACT, OR AN EXEMPTION FROM REGISTRATION UNDER
SUCH ACT."

Upon receipt of evidence satisfactory to the Company of the loss, theft,
destruction or mutilation of this Warrant, and of indemnity reasonably
satisfactory to the Company, if lost, stolen or destroyed, and upon surrender

            date of such exercise multiplied by the number of shares of Warrant
            Stock with respect to which this Warrant is then being exercised,
            payable at the Holder's election in cash by certified or official

            and delivered to the Holder hereof within a reasonable time, not
            exceeding five Trading Days after such exercise, and the Holder
            hereof shall be deemed for all purposes to be the Holder of the

            representing the number of shares of Warrant Stock, if any, with
            respect to which this Warrant shall not then have been exercised

            or partial payment of the Warrant Price as hereinabove provided)
            shall also be issued to the Holder hereof at the Issuer's expense
            within such time.

      (d)   Transferability of Warrant. Subject to the provisions of subsection
            (e) of this Section 2, this Warrant may be transferred by the Holder

            attorney, upon surrender of this Warrant at the principal office of
            the Issuer, properly endorsed (by the Holder executing an assignment
            in the form attached hereto) and upon payment of any necessary
            transfer tax or other governmental charge imposed upon such
            transfer. This Warrant is exchangeable at the principal office of
            the Issuer for Warrants for the purchase of the same aggregate
            number of shares of Warrant Stock, each new Warrant to represent the
            right to purchase such number of shares of Warrant Stock as the
            Holder hereof shall designate at the time of such exchange. All
            Warrants issued on transfers or exchanges shall be dated the
            Original Issue Date and shall be identical with this Warrant except
            as to the number of shares of Warrant Stock issuable pursuant
            hereto.

      (e)   Compliance with Securities Laws.

            (i) The Holder of this Warrant, by acceptance hereof, acknowledges

hereof are being acquired solely for the Holder's own account and not as a
nominee for any other party, and for investment, and that the Holder will not
offer, sell, transfer or otherwise dispose of this Warrant or any shares of
Warrant Stock to be issued upon exercise hereof except pursuant to an effective
registration statement, or an exemption from registration, under the Securities
Act and any applicable state securities laws.

            (ii) Except as provided in paragraph (iii) below, this Warrant and
all certificates representing shares of Warrant Stock issued upon exercise
hereof shall be stamped or imprinted with a legend in substantially the
following form:

            THIS WARRANT AND THE SHARES OF COMMON STOCK ISSUABLE UPON EXERCISE
HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED
(THE "SECURITIES ACT"), OR ANY STATE SECURITIES LAWS AND MAY NOT BE SOLD,
TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER THE SECURITIES ACT
AND UNDER APPLICABLE STATE SECURITIES LAWS OR TTR TECHNOLOGIES, INC. SHALL HAVE
RECEIVED AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE ISSUER THAT


                                       2
<PAGE>

REGISTRATION OF SUCH SECURITIES UNDER THE SECURITIES ACT AND UNDER THE
PROVISIONS OF APPLICABLE STATE SECURITIES LAWS IS NOT REQUIRED.

            (iii) The restrictions imposed by this subsection (e) upon the
transfer of this Warrant and the shares of Warrant Stock to be purchased upon
exercise hereof shall terminate (A) when such securities shall have been
effectively registered under the Securities Act, (B) upon the Issuer's receipt
of an opinion of counsel, in form and substance reasonably satisfactory to the
Issuer, addressed to the Issuer to the effect that such restrictions are no
longer required to ensure compliance with the Securities Act or (C) upon the
Issuer's receipt of other evidence reasonably satisfactory to the Issuer that
such registration is not required. Whenever such restrictions shall cease and
terminate as to any such securities, the Holder thereof shall be entitled to
receive from the Issuer (or its transfer agent and registrar), without expense
(other than applicable transfer taxes, if any), new Warrants (or, in the case of
shares of Warrant Stock, new stock certificates) of like tenor not bearing the
applicable legends required by paragraph (ii) above relating to the Securities
Act and state securities laws.

      3. Stock Fully Paid: Reservation and Listing of Shares: Covenants.

      (a) Stock Fully Paid. The Issuer represents, warrants, covenants and
agrees that all shares of Warrant Stock which may be issued upon the exercise of
this Warrant or otherwise hereunder will, upon issuance, be duly authorized,
validly issued, fully paid and non-assessable and free from all taxes, liens and
charges created by or through Issuer. The Issuer further covenants and agrees
that during the period within which this Warrant may be exercised, the Issuer
will at all times have authorized and reserved for the purpose of the issue upon
exercise of this Warrant a number of shares of Common Stock equal to at least
100% of the aggregate number of shares of Warrant Stock issuable upon the
exercise of the Warrant.

      (b) Reservation. If any shares of Common Stock required to be reserved for
issuance upon exercise of this Warrant or as otherwise provided hereunder
require registration or qualification with any governmental authority under any
federal or state law before such shares may be so issued, the Issuer will in
good faith use its best efforts as expeditiously as possible at its expense to
cause such shares to be duly registered or qualified. If the Issuer shall list
any shares of Common Stock on any securities exchange or market it will, at its
expense, list thereon, maintain and increase when necessary such listing, of,
all shares of Warrant Stock from time to time issued upon exercise of this
Warrant or as otherwise provided hereunder, and, to the extent permissible under
the applicable securities exchange rules, all unissued shares of Warrant Stock
which are at any time issuable hereunder, so long as any shares of Common Stock
shall be so listed. The Issuer will also so list on each securities exchange or
market, and will maintain such listing of, any other securities which the Holder
of this Warrant shall be entitled to receive upon the exercise of this Warrant
if at the time any securities of the same class shall be listed on such
securities exchange or market by the Issuer.

      (c) Covenants. The Issuer shall not by any action including, without
limitation, amending the Certificate of Incorporation or the by-laws of the
Issuer, or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other action, avoid or
seek to avoid the observance or performance of any of the terms of this Warrant,
but will at all times in good faith assist in the carrying out of all such terms
and in the taking of all such actions as may be necessary or appropriate to
protect the rights of the Holder hereof against dilution (to the extent
specifically provided herein) or impairment. Without limiting the generality of
the foregoing, the Issuer will (i) not permit the par value, if any, of its
Common Stock to exceed the then effective Warrant Price, (ii) not amend or
modify any provision of the Certificate of Incorporation or by-laws of the
Issuer in any manner that would adversely affect in any way the powers,
preferences or relative participating, optional or other special rights of the
Common Stock or which would adversely affect the rights of the Holder of this
Warrant, (iii) take all such action as may be reasonably necessary in order that
the Issuer


                                       3
<PAGE>

may validly and legally issue fully paid and nonassessable shares of Common
Stock, free and clear of any liens, claims, encumbrances and restrictions (other
than as provided herein) upon the exercise of this Warrant, and (iv) use its
best efforts to obtain all such authorizations, exemptions or consents from any
public regulatory body having jurisdiction thereof as may be reasonably
necessary to enable the Issuer to perform its obligations under this Warrant.

      (d) Loss, Theft, Destruction of Warrants. Upon receipt of evidence
satisfactory to the Issuer of the ownership of and the loss, theft, destruction
or mutilation of any Warrant and, in the case of any such loss, theft or
destruction, upon receipt of indemnity or security satisfactory to the Issuer
or, in the case of any such mutilation, upon surrender and cancellation of such
Warrant, the Issuer will make and deliver, in lieu of such lost, stolen,
destroyed or mutilated Warrant, a new Warrant of like tenor and representing the
right to purchase the same number of shares of Common Stock.

      4. Registration Rights Under The Securities Act


            The Holder shall have the registration rights granted to the Holder
in the Registration Rights Agreement of even date hereof between the Holder and
the Company.

      5. Adjustment of Warrant Price and Warrant Share Number. The number and
kind of Securities purchasable upon the exercise of this Warrant and the Warrant
Price shall be subject to adjustment from time to time upon the happening of
certain events as follows:

      (a)   Recapitalization, Reorganization, Reclassification, Consolidation,
            Merger or Sale.

            (i) In case the Issuer after the Original Issue Date shall do any of
      the following (each, a "Triggering Event"): (a) consolidate with or merge
      into any other Person and the Issuer shall not be the continuing or
      surviving corporation of such consolidation or merger; provided, however,
      that a merger for the sole purpose of effecting a change in domicile of
      the Issuer from one state to another shall not be deemed a Triggering
      Event, or (b) permit any other Person to consolidate with or merge into
      the Issuer and the Issuer shall be the continuing or surviving Person but,
      in connection with such consolidation or merger, any Capital Stock of the
      Issuer shall be changed into or exchanged for Securities of any other
      Person or cash or any other property, or (c) transfer all or substantially
      all of its properties or assets to any other Person, or (d) effect a
      capital reorganization or reclassification of its Capital Stock, then, and
      in the case of each such Triggering Event, proper provision shall be made
      so that, upon the basis and the terms and in the manner provided in this
      Warrant, the Holder of this Warrant shall be entitled upon the exercise
      hereof at any time after the consummation of such Triggering Event, to the
      extent this Warrant is not exercised prior to such Triggering Event, or is
      redeemed in connection with such Triggering Event, to receive at the
      Warrant Price in effect at the time immediately prior to the consummation
      of such Triggering Event in lieu of the Common Stock issuable upon such
      exercise of this Warrant prior to such Triggering Event, the Securities,
      cash and property to which the Holder would have been entitled upon the
      consummation of such Triggering Event if the Holder had exercised the
      rights represented by this Warrant immediately prior thereto, subject to
      adjustments and increases (subsequent to such corporate action) as nearly
      equivalent as possible to the adjustments provided for in Section 4 hereof

      (b) Subdivision or Combination of Shares. If the Issuer, at any time while
this Warrant is outstanding, shall subdivide or combine any shares of Common
Stock, (i) in case of subdivision of shares, the Warrant Price shall be
proportionately reduced (as at the effective date of such subdivision or, if the
Issuer shall take a record of holders of its Common Stock for the purpose of so
subdividing, as at the applicable record date, whichever is earlier) to reflect
the


                                       4
<PAGE>

increase in the total number of shares of Common Stock outstanding as a result
of such subdivision, or (ii) in the case of a combination of shares, the Warrant
Price shall be proportionately increased (as at the effective date of such
combination or, if the Issuer shall take a record of holders of its Common Stock
for the purpose of so combining, as at the applicable record date, whichever is
earlier) to reflect the reduction in the total number of shares of Common Stock
outstanding as a result of such combination.

      (c) Issuance of Additional Shares of Common Stock. If at any time the
Company shall issue any Additional Shares of Common Stock at a price per share
which is lower than $5.56, then the number of shares of Common Stock to be
received by the holder of this Warrant upon the exercise hereof shall be
adjusted to that number determined by multiplying [(a) the number of shares of
Common Stock purchasable hereunder immediately prior thereto by (b) a fraction
(i) the numerator of which shall be the sum of (A) the number of shares of
Common Stock Deemed Outstanding immediately prior to the issuance of such shares
of Common Stock plus (B) the number of shares of Common Stock issued in the
subject transaction and (ii) the denominator of which shall be an amount equal
to the sum of (x) the number of shares of Common Stock Deemed Outstanding
immediately prior to the issuance of such shares of Common Stock plus (y) the
quotient of (1) the Offering Price multiplied by the number of shares of Common
Stock so issued by the Company, divided by (2) $5.56. The foregoing provisions
shall not apply to Additional Shares (A) if price per share (or in the case of
an option or warrant, the exercise price thereof) is not less than $5.00 and the
gross proceeds received or receivable by the Company as consideration for the
issue of such Additional Shares, 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 Additional Shares, equals or
exceeds $1,500,000 (B) (ii) any capital stock or other securities offered or
issued in connection with any acquisition of another corporation or entity by
the Company by merger or purchase of all, or substantially all, of the assets of
such corporation or entity, share exchange, reorganization or the like (C) any
capital stock or other securities issued in connection with any stock split,
stock dividend, recapitalization or the like by the Company.;

      (d) Certain Dividends and Distributions. If the Issuer, at any time while
this Warrant is outstanding, shall:

            (i) Common Stock Dividends. Pay a dividend in, or make any other
      distribution to its stockholders (without consideration therefor) of,
      shares of Common Stock, the Warrant Price shall be adjusted, as at the
      date the Issuer shall take a record of the holders the Issuer's Capital
      Stock for the purpose of receiving such dividend or other distribution (or
      if no such record is taken, as at the date of such payment or other
      distribution), to that price determined by multiplying the Warrant Price
      in effect immediately prior to such record date (or if no such record is
      taken, then immediately prior to such payment or other distribution), by a
      fraction (1) the numerator of which shall be the total number of shares of
      Common Stock outstanding immediately prior to such dividend or
      distribution, and (2) the denominator of which shall be the total number
      of shares of Common Stock outstanding immediately after such dividend or
      distribution (plus in the event that the Issuer paid cash for fractional
      shares, the number of additional shares which would have been outstanding
      had the Issuer issued fractional shares in connection with said
      dividends); or

            (ii) Other Dividends. Pay a dividend on, or make any distribution of
      its assets upon or with respect to (including, but not limited to, a
      distribution of its property as a dividend in liquidation or partial
      liquidation or by way of return of capital), the Common Stock (other than
      as described in clause (i) of this subsection (c)), or in the event that
      the Issuer shall offer options or rights to subscribe for shares of Common
      Stock, or issue any Common Stock Equivalents, to all of its holders of
      Common Stock, then on the record date for such payment, distribution or
      offer or, in the absence of a record date, on the date of such

                                       5
<PAGE>

      payment, distribution or offer, the Holder shall receive what the Holder
      would have received had it exercised this Warrant in full immediately
      prior to the record date of such payment, distribution or offer or, in the
      absence of a record date, immediately prior to the date of such payment,
      distribution or offer.

      (e) Other Provisions Applicable to Adjustments Under this Section 5. The
following provisions shall be applicable to the making of adjustments in the
Warrant Price hereinbefore provided in Section 4. The number of shares of Common
Stock at any time outstanding shall (A) not include any shares thereof then
directly or indirectly owned or held by or for the account of the Issuer or any
of its Subsidiaries, and (B) be deemed to include all shares of Common Stock
then issuable upon conversion, exercise or exchange of any then outstanding
Common Stock Equivalents or any other evidences of indebtedness, shares of
Capital Stock (including, without limitation, the Preferred Stock) or other
Securities which are or may be at any time convertible into or exchangeable for
shares of Common Stock or Other Common Stock.

      (f) Other Action Affecting Common Stock. In case after the Original Issue
Date the Issuer shall take any action affecting its Common Stock, other than an
action described in any of the foregoing subsections (a) through (d) of this
Section 5, inclusive, then the Warrant Price shall be adjusted in such manner
and at such time as the Board may in good faith determine to be equitable in the
circumstances.

      (g) Adjustment of Warrant Share Number. Upon each adjustment in the
Warrant Price pursuant to the provisions (b) and (c)(i) of this Section 5, the
Warrant Share Number shall be adjusted, to the nearest one hundredth of a whole
share, to the product obtained by multiplying the Warrant Share Number
immediately prior to such adjustment in the Warrant Price by a fraction, the
numerator of which shall be the Warrant Price immediately before giving effect
to such adjustment and the denominator of which shall be the Warrant Price
immediately after giving effect to such adjustment. If the Issuer shall be in
default under any provision contained in Section 3 of this Warrant so that
shares issued at the Warrant Price adjusted in accordance with this Section 4
would not be validly issued, the adjustment of the Warrant Share Number provided
for in the foregoing sentence shall nonetheless be made and the Holder of this
Warrant shall be entitled to purchase such greater number of shares at the
lowest price at which such shares may then be validly issued under applicable
law. Such exercise shall not constitute a waiver of any claim arising against
the Issuer by reason of its default under Section 3 of this Warrant.

      (h) Form of Warrant after Adjustments. The form of this Warrant need not
be changed because of any adjustments in the Warrant Price or the number and
kind of Securities purchasable upon the exercise of this Warrant.

      (i) Continuation of Terms. Upon any reorganization, consolidation, merger
or transfer (and any dissolution following any transfer) referred to in this
section 5, this Warrant shall continue in full force and effect and the terms
hereof shall be applicable to the shares of stock and other securities and
property receivable on the exercise of this Warrant after the consummation of
such reorganization, consolidation, or merger or the effective date of
dissolution following any such transfer, as the case may be, and shall be
binding upon the issuer of any such stock or other securities, including, in the
case of any such transfer, the person acquiring all or substantially all of the
properties or assets of the Company, whether or not such person shall have
expressly assumed the terms of this Warrant.

      6. Notice of Adjustments. Whenever the Warrant Price or Warrant Share
Number shall be adjusted pursuant to Section 5 hereof (for purposes of this
Section 6, each an "adjustment"), the Issuer shall cause its Chief Financial
Officer to prepare and execute a


                                       6
<PAGE>

certificate setting forth, in reasonable detail, the event requiring the
adjustment, the amount of the adjustment, the method by which such adjustment
was calculated (including a description of the basis on which the Board made any
determination hereunder), and the Warrant Price and Warrant Share Number after
giving effect to such adjustment, and shall cause copies of such certificate to
be delivered to the Holder of this Warrant promptly after each adjustment. Any
dispute between the Issuer and the Holder of this Warrant with respect to the
matters set forth in such certificate may at the option of the Holder of this
Warrant be submitted to one of the national accounting firms currently known as
the "big five" mutually agreed upon by the Issuer and the Holder or, in the
event the Issuer and the Holder are unable to agree, a "big five" national
accounting firm (other than the Issuer's independent auditors) selected by the
Issuer's independent auditors. The firm selected in the manner as provided in
the preceding sentence shall be instructed to deliver a written opinion as to
such matters to the Issuer and the Holder within thirty days after submission to
it of such dispute. Such opinion shall be final and binding on the parties
hereto. The fees and expenses of such accounting firm shall be paid by the
Issuer.

      7. Fractional Shares. No fractional shares of Warrant Stock will be issued
in connection with and exercise hereof, but in lieu of such fractional shares,
the Issuer shall make a cash payment therefor equal in amount to the product of
the applicable fraction multiplied by the Per Share Market Value then in effect.

      8. Redemption of Warrants. The Company may redeem the Class A Warrants for
$.10 per warrant 6 months following issuance if the underlying common stock is
registered and the Company's common shares have traded at or above 200% of the
warrant exercise price (the "trigger price") for a period of twenty consecutive
trading days.

      9. Issuance of Class B Warrants. Upon exercise of the Class A Warrants,
the investors will be issued Class B warrants for such number of shares as shall
equal one half the number of shares for which this Class A warrants is exercised
with a term of 36 months and an exercise price of 120% of the Class A Warrant
trigger price. The Class B warrants may be redeemed by the Company if the

provision hereof is found to be unenforceable, then such provision shall be
deemed modified to the extent necessary to make it enforceable by such court or
agency. If any such provision is not enforceable as set forth in the preceding
sentence, the unenforceability of such provision shall not affect the other
provisions of this Warrant, but this Warrant shall be construed as if such

                                          Stock of TTR Technologies, Inc.

      FOR VALUE RECEIVED, TTR TECHNOLOGIES INC., a Delaware company (the
"Company"), hereby grants to MANTLE INTERNATIONAL INVESTMENT LTD. (the
"Holder"), the right to purchase, subject to the terms and conditions hereof,
200,000 fully paid and non-assessable shares of Common Stock of the Company, par
value $0.001, (the "Shares"). The purchase price for each Share purchased

Hereinafter, (i) such Shares, together with any other equity security which may
be issued by the Company in substitution therefor, are referred to as the
"Shares"; (ii) the shares purchasable hereunder are referred to as the "Warrant
Shares"; (iii) and the price payable hereunder for each of the Warrant Shares,
as adjusted in the manner set froth hereinafter, is referred to as the "Per
Share Warrant Price"; and (iv) this warrant and all warrants hereafter issued in

1.1 This Warrant may be exercised in whole or in part at any time commencing
9:00 a.m., New York City time, on the date set forth above through January 31,
2001 (the "Warrant Period") by the surrender of this Warrant (with a duly
executed exercise form in the form attached at the end hereof as Exhibit A) at

of the Investment. As used herein, the term "Investment" shall mean the closing
of a private investment in the Company with gross proceeds equal to or exceeding
$7,500,000.

a certificate or certificates for the number of Warrant Shares being purchased,
and such certificate or

<PAGE>

certificates shall be deemed to have been issued and any person so designated to
be named therein shall be deemed to have become a holder of the such Shares as
of the close of business on the date of the surrender of the Warrant and payment
of the Per Share Warrant Price. If this warrant should be exercised in part
only, the Company shall, upon surrender of the Warrant for cancellation, execute
and deliver a new Warrant evidencing the rights of the Holder hereof to purchase
the balance of the Shares purchasable hereunder.

1.3 Any stamp tax attributable to the issuance of the Shares shall be borne
solely by Holder.

2. Representations and Warranties

2.1 The Holder (i) represents, warrants, covenants and agrees that the Warrant
and the underlying Warrant Shares are being acquired by the Holder for the
Holder's own account, for investment purposes only, and not with a view to or
for sale in connection with any distribution thereof or with any present
intention of selling or distributing all or any part of the Warrant or the
underlying Warrant Shares thereof; (ii) understands (x) that if it should
thereafter decide to dispose of such Warrant or Warrant Shares (which it does
not contemplate at such time) it may do so only in compliance with the
Securities Act, (y) this Warrant and the Warrant Shares are not registered under
the Securities Act nor does the Company have any obligation to register this
Warrant and the Warrant Shares (except as provided in paragraph 3 below) and (z)
that it is unlikely that Rule 144 adopted by the Securities and Exchange
Commission will be applicable to permit sales of this Warrant and the Warrant
Shares in reliance thereon; and (iii) acknowledges that, as of the date hereof,
it has been given a full opportunity to ask questions of and to receive answers
from the Company concerning this Warrant and the Warrant Shares and the business
of the Company and to obtain such information as it desired in order to evaluate
the acquisition of this Warrant and the Warrant Shares, and all questions have
been answered to its full satisfaction.

3. Reservation of Shares.

The Company has reserved, and shall at all times so long as any Warrant remains
outstanding, keep reserved, out of its authorized and unissued capital stock,
such number of shares of Common Stock, par value $0.001, as shall be subject to
purchase under the Warrant.

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

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

<PAGE>

6. Stock Dividends, Reclassifications, Reorganization, Anti-Dilution Provisions,
Etc.

6.1 In case prior to the expiration of this Warrant by exercise or by its terms
the Company shall issue any shares of its Common Stock as a stock dividend or
subdivide the number of outstanding shares of Common Stock into a greater number
of shares, then, in either of such cases, the Exercise Price per share of the
Warrant Shares purchasable pursuant to this Warrant in effect at the time of
such action shall be proportionately reduced and the number of Warrant Shares
purchasable at that time shall be proportionately increased; and, conversely, in
the event the Company shall contract the number of outstanding shares of Common
Stock by combining such shares into a smaller number of shares, then, in such
case, the Exercise Price per share of the Warrant Shares purchasable pursuant to
this Warrant shall be proportionately decreased. Any dividend paid or
distributed upon the Common Stock in stock of any other class of securities
convertible into shares of Common Stock shall be treated as a dividend paid in
Common Stock to the extent that shares of Common Stock are issuable upon
conversion thereof.

6.2 In case of any consolidation or merger of the Company with or into another
corporation (other than a merger or consolidation in which the Company is the
surviving or the continuing corporation) or in the case of any sale or
conveyance to another corporation or other entity of the property, assets or
business of the Company as an entirety or substantially as an entirety, in any
such case, the Company or such successor or purchasing corporation or entity, as
the case may be, shall (i) execute with the Holder an agreement that the Holder
shall have the right thereafter to receive upon the exercise of the Warrant the
kind and amount of shares and/or other securities or other property which he
would have owned or have been entitled to receive after the happening of such
consolidation, merger, sale or conveyance had the Warrant been exercised
immediately prior to such action, (ii) make effective provision in its
certificate of its incorporation or otherwise, if necessary, in order to effect
such agreement, and (iii) set aside or reserve for the benefit of the Holder,
the stock, securities, property and cash to which the Holder would be entitled
to upon exercise of this Warrant.

6.3 In case of any reclassification or change of the Warrant Shares issuable
upon exercise of this Warrant (other than a change in par value or from no par
value to a specific par value, or as a result of a subdivision or combination,
including any change in the shares into two or more classes or series of
shares), or in the case of any consolidation or merger of another corporation
into the Company in which the Company is the continuing corporation and in which
there is a reclassification or change (including a change in the right to
receive cash or other property) of the Shares (other than a change in the par
value, or from no par value to a specific par value or, as a result of a
subdivision or combination, including any change in the shares into two or more
classes or series of shares), Holder shall have the right thereafter to receive
upon exercise of this Warrant solely the kind and amount of shares of stock and
other securities, property, cash or combination thereof receivable upon such
reclassification, change, consolidation or merger by a holder of the number of
Shares for which this Warrant might have been exercised immediately prior to
such reclassification, change, consolidation or merger.

<PAGE>

6.4 Upon the occurrence of each event requiring an adjustment of the Exercise
Price and the number of Warrant Shares purchasable at such adjusted Exercise
Price by reason of such event in accordance with the provision of this Section
6, the Company shall compute the adjusted Exercise Price and the adjusted number
of Warrant Shares purchasable at such adjusted Exercise Price by reason of such
event in accordance with the provisions of this Section 6 and shall prepare a
certificate setting forth such adjusted Exercise Price and the adjusted number
of Warrant Shares and showing in reasonable detail the facts upon which such
determination is made. The Company shall mail to the holder of this Warrant a
copy of such Certificate, and thereafter said certificate shall be conclusive
and shall be binding upon such holder unless contested by such holder in a
written notice furnished to the Company within 15 days of the receipt thereof
setting forth in reasonable detail the basis of such contention.

6.5 In case:

(a) the Company shall take a record of the holders of its Common Stock for the
purpose of entitling them to receive a dividend or any other distribution in
respect of the Common Stock (including cash), pursuant to without limitation,
any spin-off, split-off or distribution of the Company's assets; or

(b) the Company shall take a record of the holders of its Common Stock for the
purpose of entitling them to subscribe for or purchase any shares of stock of
any class or to receive any other rights; or

(c) of any classification, reclassification or other reorganization of the
capital stock of the Company, consolidation or merger of the Company with or
into another corporation, or conveyance of all or substantially all of the
assets of the Company; or

(d) of the voluntary or involuntary dissolution, liquidation or winding up of
the Company;

then, and in any such case, the Company shall mail to the Holder, at least
twenty (20) days prior thereto, a notice stating the date or expected date on
which a record is to be taken for the purpose of such dividend or distribution
of rights, or the date on which such classification, reclassification,
reorganization, consolidation, merger, conveyance, dissolution, liquidation, or
winding up is to take place, as the case may be. Such notice shall also specify
the date or expected date, if any is to be fixed, as of which holders of Common
Stock of record shall be entitled to participate in said dividend on
distribution of rights, or shall be entitled to exchange their shares of Common
stock for securities or other property deliverable upon such classification,
reclassification, reorganization, consolidation, merger, conveyance,
dissolution, liquidation, or winding up, as the case may be. The failure to give
such notice shall not affect the validity of any such proceeding or transaction
and shall not affect the right of the holder of this Warrant to participate in
said dividend, distribution of rights, or any such exchange and acquire the kind
and amount of cash, securities or other property as the Holder would have been
entitled to acquire if it was the record holder of the Warrant Shares which
could be obtained upon the exercise of the Warrants immediately before such
proceeding or transaction; provided that the Holder

<PAGE>

exercises the Warrants within 30 days after discovery that such action or
proceeding has taken place.

6.6 In case the Company at any time while this Warrant shall remain unexpired
and unexercised, shall dissolve, liquidate, or wind up its affairs, the holder
of this Warrant may thereafter receive upon exercise hereof in lieu of each
share of Common Stock of the Company which it would have been entitled to
receive, the same kind and amount of any securities or assets as may be
issuable, distributable or payable upon any such dissolution, liquidation or
winding up with respect to each share of Common Stock of the Company.

7. Limited Transfer

7.1 The Company may treat the registered holder of record as the holder for all
purposes.

7.2 In no event shall the Company be obligated to effect any transfer of
Warrants or Warrant Shares unless a registration statement is in effect with
respect thereto under applicable state and Federal securities laws or unless the
Company shall have received an opinion in substance reasonably satisfactory to
it from counsel that such registration is not required. Unless registered, the
Warrant Shares issued upon exercise of the Warrant shall be subject to a stop
transfer order and the certificate or certificates evidencing such Warrant

      FOR VALUE RECEIVED, subject to the provisions hereinafter set forth, the
undersigned, TTR Technologies, Inc., a Delaware corporation (together with its
successors and assigns, the "Issuer"), hereby certifies that _________________
or its registered permitted assigns is entitled to subscribe for and purchase,
during the period specified in this Warrant, up to _________ shares (subject to
adjustment as hereinafter provided) of the duly authorized, validly issued,
fully paid and non-assessable Common Stock of the Issuer, at an exercise price
per share of Five dollars and fifty six cents ($5.56) and up to _____ Class A
Agent Warrants to purchase Common Stock at ($8.84) per share at an exercise
price of ($.01) per Warrant, subject, however, to the provisions and upon the
terms and conditions hereinafter set forth. Capitalized terms used in this
Warrant and not otherwise defined herein shall have the respective meanings
specified in Section 8 hereof.

      1. Term. The right to subscribe for and purchase shares of Warrant Stock
represented hereby shall commence on the date of issuance of this Warrant and
shall expire at  5:00 p.m., New York Time, on March 1, 2005 (the "Initial
Term"), provided, that, if at the date of the expiration of the Initial Term,
(A) the Warrant Stock shall not be listed on the OTC Bulletin Board, the Nasdaq
SmallCap Market, the Nasdaq National Market, The New York Stock Exchange, Inc.
or The American Stock Exchange, Inc. or (B) the Issuer shall not have sufficient
shares of Warrant Stock issuable upon a full exercise of this Warrant, then the
Initial Term shall be extended until the first such date on which none of the
foregoing events shall exist (the Initial Term, as such may be extended, being
hereinafter called the "Term").

      2. Method of Exercise Payment: Issuance of New Warrant: Transfer and
Exchange.

      (a) Time of Exercise. The purchase rights represented by this Warrant may
be exercised in whole or in part at any time and from time to time during the
Term.

      Method of Exercise. (i) The Holder hereof may exercise this Warrant, in
whole or in part, by the surrender of this Warrant (with the exercise form
attached hereto duly executed) at the


                                       1
<PAGE>

principal office of the Issuer, and by the payment to the Issuer of an amount of
consideration therefor equal to the Warrant Price in effect on the date of such
exercise multiplied by the number of shares of Warrant Stock with respect to
which this Warrant is then being exercised, payable at the Holder's election in
cash by certified or official bank check or wire transfer, (ii) at any time on
or after the Original Issue Date by surrender to the Issuer for cancellation of
a portion of this Warrant representing that number of unissued shares of Warrant
Stock which is equal to the quotient obtained by dividing (A) the product
obtained by multiplying the Warrant Price by the number of shares of Warrant
Stock being purchased upon such exercise by (B) the difference obtained by
subtracting the Warrant Price from the Per Share Market Value as of the date of
such exercise ("Cashless Exercise by surrender of Warrant) or (iii) by a
combination of the foregoing methods of payment selected by the Holder of this
Warrant. In any case where the consideration payable upon such exercise is being
paid in whole or in part pursuant to the provisions of clause (ii) of this
subsection (b), such exercise shall be accompanied by written notice from the
Holder of this Warrant specifying the manner of payment thereof and containing a
calculation showing the number of shares of Warrant Stock with respect to which
rights are being surrendered thereunder and the net number of shares to be
issued after giving effect to such surrender. For purposes of the cashless
exercise provision, per share market value shall be calculated either (i) on the
date the Warrant exercise is delivered to the Company ("Notice Date") or (ii) as
the average closing Market Price for each of the five trading days preceding the
Notice Date, whichever of (i) or (ii) is greater. Notwithstanding anything in
this Warrant to the contrary, any remaining unexercised portion of this Warrant
shall be deemed to have been exercised immediately prior to the Expiration Date,
pursuant to a cashless exercise and the Company shall issue that number of
shares of common stock as provided for based on the method described under the
Cashless Exercise provision above.

      (b) Issuance of Stock Certificates. In the event of any exercise of the
rights represented by this Warrant in accordance with and subject to the terms
and conditions hereof, (i) certificates for the shares of Warrant Stock so
purchased shall be dated the date of such exercise and delivered to the Holder
hereof within a reasonable time, not exceeding three Trading Days after such
exercise, and the Holder hereof shall be deemed for all purposes to be the
Holder of the shares of Warrant Stock so purchased as of the date of such
exercise, and (ii) unless this Warrant has expired, a new Warrant representing
the number of shares of Warrant Stock, if any, with respect to which this
Warrant shall not then have been exercised (less any amount thereof which shall
have been canceled in payment or partial payment of the Warrant Price as
hereinabove provided) shall also be issued to the Holder hereof at the Issuer's
expense within such time.

      (c) Transferability of Warrant. Subject to the provisions of subsection
(e) of this Section 2, this Warrant may be transferred by the Holder without the
consent of the Issuer. If transferred pursuant to this paragraph, and subject to
the provisions of subsection (e) of this Section 2, this Warrant may be
transferred on the books of the Issuer by the Holder hereof in person or by duly
authorized attorney, upon surrender of this Warrant at the principal office of
the Issuer, properly endorsed (by the Holder executing an assignment in the form
attached hereto) and upon payment of any necessary transfer tax or other
governmental charge imposed upon such transfer. This Warrant is exchangeable at
the principal office of the Issuer for Warrants for the purchase of the same
aggregate number of shares of Warrant Stock, each new Warrant to represent the
right to purchase such number of shares of Warrant Stock as the Holder hereof
shall designate at the time of such exchange. All Warrants issued on transfers
or exchanges shall be dated the Original Issue Date and shall be identical with
this Warrant except as to the number of shares of Warrant Stock issuable
pursuant hereto.

      (d) Compliance with Securities Laws.

            (i) The Holder of this Warrant, by acceptance hereof, acknowledges
that this Warrant and the shares of Warrant Stock to be issued upon exercise
hereof are being acquired


                                       2
<PAGE>

solely for the Holder's own account and not as a nominee for any other party,
and for investment, and that the Holder will not offer, sell, transfer or
otherwise dispose of this Warrant or any shares of Warrant Stock to be issued
upon exercise hereof except pursuant to an effective registration statement, or
an exemption from registration, under the Securities Act and any applicable
state securities laws.

            (ii) Except as provided in paragraph (iii) below, this Warrant and
all certificates representing shares of Warrant Stock issued upon exercise
hereof shall be stamped or imprinted with a legend in substantially the
following form:

            THIS WARRANT AND THE SHARES OF COMMON STOCK ISSUABLE UPON EXERCISE
HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED
(THE "SECURITIES ACT"), OR ANY STATE SECURITIES LAWS AND MAY NOT BE SOLD,
TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER THE SECURITIES ACT
AND UNDER APPLICABLE STATE SECURITIES LAWS OR TTR TECHNOLOGIES, INC. SHALL HAVE
RECEIVED AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE ISSUER THAT
REGISTRATION OF SUCH SECURITIES UNDER THE SECURITIES ACT AND UNDER THE
PROVISIONS OF APPLICABLE STATE SECURITIES LAWS IS NOT REQUIRED.

            (iii) The restrictions imposed by this subsection (e) upon the
transfer of this Warrant and the shares of Warrant Stock to be purchased upon
exercise hereof shall terminate (A) when such securities shall have been
effectively registered under the Securities Act, (B) upon the Issuer's receipt
of an opinion of counsel, in form and substance reasonably satisfactory to the
Issuer, addressed to the Issuer to the effect that such restrictions are no
longer required to ensure compliance with the Securities Act or (C) upon the
Issuer's receipt of other evidence reasonably satisfactory to the Issuer that
such registration is not required. Whenever such restrictions shall cease and
terminate as to any such securities, the Holder thereof shall be entitled to
receive from the Issuer (or its transfer agent and registrar), without expense
(other than applicable transfer taxes, if any), new Warrants (or, in the case of
shares of Warrant Stock, new stock certificates) of like tenor not bearing the
applicable legends required by paragraph (ii) above relating to the Securities
Act and state securities laws.

      3. Stock Fully Paid: Reservation and Listing of Shares: Covenants.

      (a) Stock Fully Paid. The Issuer represents, warrants, covenants and
agrees that all shares of Warrant Stock which may be issued upon the exercise of
this Warrant or otherwise hereunder will, upon issuance, be duly authorized,
validly issued, fully paid and non-assessable and free from all taxes, liens and
charges created by or through Issuer. The Issuer further covenants and agrees
that during the period within which this Warrant may be exercised, the Issuer
will at all times have authorized and reserved for the purpose of the issue upon
exercise of this Warrant a number of shares of Common Stock equal to at least
100% of the aggregate number of shares of Warrant Stock issuable upon the
exercise of the Warrant.

      (b) Reservation. If any shares of Common Stock required to be reserved for
issuance upon exercise of this Warrant or as otherwise provided hereunder
require registration or qualification with any governmental authority under any
federal or state law before such shares may be so issued, the Issuer will in
good faith use its best efforts as expeditiously as possible at its expense to
cause such shares to be duly registered or qualified. If the Issuer shall list
any shares of Common Stock on any securities exchange or market it will, at its
expense, list thereon, maintain and increase when necessary such listing, of,
all shares of Warrant Stock from time to time issued upon exercise of this
Warrant or as otherwise provided hereunder, and, to the extent permissible under
the applicable securities exchange rules, all unissued shares of Warrant Stock
which are at any time issuable hereunder, so long as any shares of Common Stock
shall be so listed. The Issuer will also so list on each securities exchange or
market, and will maintain such


                                       3
<PAGE>

listing of, any other securities which the Holder of this Warrant shall be
entitled to receive upon the exercise of this Warrant if at the time any
securities of the same class shall be listed on such securities exchange or
market by the Issuer.

      (c) Covenants. The Issuer shall not by any action including, without
limitation, amending the Certificate of Incorporation or the by-laws of the
Issuer, or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other action, avoid or
seek to avoid the observance or performance of any of the terms of this Warrant,
but will at all times in good faith assist in the carrying out of all such terms
and in the taking of all such actions as may be necessary or appropriate to
protect the rights of the Holder hereof against dilution (to the extent
specifically provided herein) or impairment. Without limiting the generality of
the foregoing, the Issuer will (i) not permit the par value, if any, of its
Common Stock to exceed the then effective Warrant Price, (ii) not amend or
modify any provision of the Certificate of Incorporation or by-laws of the
Issuer in any manner that would adversely affect in any way the powers,
preferences or relative participating, optional or other special rights of the
Common Stock or which would adversely affect the rights of the Holder of this
Warrant, (iii) take all such action as may be reasonably necessary in order that
the Issuer may validly and legally issue fully paid and nonassessable shares of
Common Stock, free and clear of any liens, claims, encumbrances and restrictions
(other than as provided herein) upon the exercise of this Warrant, and (iv) use
its best efforts to obtain all such authorizations, exemptions or consents from
any public regulatory body having jurisdiction thereof as may be reasonably
necessary to enable the Issuer to perform its obligations under this Warrant.

      (d) Loss, Theft, Destruction of Warrants. Upon receipt of evidence
satisfactory to the Issuer of the ownership of and the loss, theft, destruction
or mutilation of any Warrant and, in the case of any such loss, theft or
destruction, upon receipt of indemnity or security satisfactory to the Issuer
or, in the case of any such mutilation, upon surrender and cancellation of such
Warrant, the Issuer will make and deliver, in lieu of such lost, stolen,
destroyed or mutilated Warrant, a new Warrant of like tenor and representing the
right to purchase the same number of shares of Common Stock.

      4. Registration Rights Under The Securities Act

            The Company is currently preparing a registration statement under
      the Securities Act of 1933, as amended, covering the resale of by certain
      shareholders of shares of Common Stock of the Company, which registration
      statement the Company intends to shortly file (the "Registration
      Statement"). The Warrant Shares shall be included in such registration
      statement. In the event that the Registration Statement shall not be
      effective, then upon the request of the Holder, the Company shall file a
      registration statement respecting the resale of the Warrant Shares.

      5. Adjustment of Warrant Price and Warrant Share Number. The number and
kind of Securities purchasable upon the exercise of this Warrant and the Warrant
Price shall be subject to adjustment from time to time upon the happening of
certain events as follows:

      (a) Recapitalization, Reorganization, Reclassification, Consolidation,
Merger or Sale.

                  (i) In case the Issuer after the Original Issue Date shall do
      any of the following (each, a "Triggering Event"): (a) consolidate with or
      merge into any other Person and the Issuer shall not be the continuing or
      surviving corporation of such consolidation or merger; provided, however,
      that a merger for the sole purpose of effecting a change in domicile of
      the Issuer from one state to another shall not be deemed a Triggering
      Event, or (b) permit any other Person to consolidate with or merge into
      the Issuer and the Issuer shall be the continuing or surviving Person but,
      in connection with such consolidation or merger, any Capital Stock of the
      Issuer shall be changed into or exchanged for Securities of any other


                                       4
<PAGE>

      Person or cash or any other property, or (c) transfer all or substantially
      all of its properties or assets to any other Person, or (d) effect a
      capital reorganization or reclassification of its Capital Stock, then, and
      in the case of each such Triggering Event, proper provision shall be made
      so that, upon the basis and the terms and in the manner provided in this
      Warrant, the Holder of this Warrant shall be entitled upon the exercise
      hereof at any time after the consummation of such Triggering Event, to the
      extent this Warrant is not exercised prior to such Triggering Event, or is
      redeemed in connection with such Triggering Event, to receive at the
      Warrant Price in effect at the time immediately prior to the consummation
      of such Triggering Event in lieu of the Common Stock issuable upon such
      exercise of this Warrant prior to such Triggering Event, the Securities,
      cash and property to which the Holder would have been entitled upon the
      consummation of such Triggering Event if the Holder had exercised the
      rights represented by this Warrant immediately prior thereto, subject to
      adjustments and increases (subsequent to such corporate action) as nearly
      equivalent as possible to the adjustments provided for in Section 4 hereof

      (b) Subdivision or Combination of Shares. If the Issuer, at any time while
this Warrant is outstanding, shall subdivide or combine any shares of Common
Stock, (i) in case of subdivision of shares, the Warrant Price shall be
proportionately reduced (as at the effective date of such subdivision or, if the
Issuer shall take a record of holders of its Common Stock for the purpose of so
subdividing, as at the applicable record date, whichever is earlier) to reflect
the increase in the total number of shares of Common Stock outstanding as a
result of such subdivision, or (ii) in the case of a combination of shares, the
Warrant Price shall be proportionately increased (as at the effective date of
such combination or, if the Issuer shall take a record of holders of its Common
Stock for the purpose of so combining, as at the applicable record date,
whichever is earlier) to reflect the reduction in the total number of shares of
Common Stock outstanding as a result of such combination.

      (c) Issuance of Additional Shares of Common Stock. If at any time the
Company shall issue any Additional Shares of Common Stock at a price per share
which is lower than $5.56, then the number of shares of Common Stock to be
received by the holder of this Warrant upon the exercise hereof shall be
adjusted to that number determined by multiplying [(a) the number of shares of
Common Stock purchasable hereunder immediately prior thereto by (b) a fraction
(i) the numerator of which shall be the sum of (A) the number of shares of
Common Stock Deemed Outstanding immediately prior to the issuance of such shares
of Common Stock plus (B) the number of shares of Common Stock issued in the
subject transaction and (ii) the denominator of which shall be an amount equal
to the sum of (x) the number of shares of Common Stock Deemed Outstanding
immediately prior to the issuance of such shares of Common Stock plus (y) the
quotient of (1) the Offering Price multiplied by the number of shares of Common
Stock so issued by the Company, divided by (2) $5.56. The foregoing provisions
shall not apply to Additional Shares (A) if price per share (or in the case of
an option or warrant, the exercise price thereof) is not less than $5.00 and the
gross proceeds received or receivable by the Company as consideration for the
issue of such Additional Shares, 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 Additional Shares, equals or
exceeds $1,500,000 (B) (ii) any capital stock or other securities offered or
issued in connection with any acquisition of another corporation or entity by
the Company by merger or purchase of all, or substantially all, of the assets of
such corporation or entity, share exchange, reorganization or the like (C) any
capital stock or other securities issued in connection with any stock split,
stock dividend, recapitalization or the like by the Company.

      (d) Certain Dividends and Distributions. If the Issuer, at any time while
this Warrant is outstanding, shall:


                                       5
<PAGE>

            (i) Common Stock Dividends. Pay a dividend in, or make any other
      distribution to its stockholders (without consideration therefor) of,
      shares of Common Stock, the Warrant Price shall be adjusted, as at the
      date the Issuer shall take a record of the holders the Issuer's Capital
      Stock for the purpose of receiving such dividend or other distribution (or
      if no such record is taken, as at the date of such payment or other
      distribution), to that price determined by multiplying the Warrant Price
      in effect immediately prior to such record date (or if no such record is
      taken, then immediately prior to such payment or other distribution), by a
      fraction (1) the numerator of which shall be the total number of shares of
      Common Stock outstanding immediately prior to such dividend or
      distribution, and (2) the denominator of which shall be the total number
      of shares of Common Stock outstanding immediately after such dividend or
      distribution (plus in the event that the Issuer paid cash for fractional
      shares, the number of additional shares which would have been outstanding
      had the Issuer issued fractional shares in connection with said
      dividends); or

            (ii) Other Dividends. Pay a dividend on, or make any distribution of
      its assets upon or with respect to (including, but not limited to, a
      distribution of its property as a dividend in liquidation or partial
      liquidation or by way of return of capital), the Common Stock (other than
      as described in clause (i) of this subsection (c)), or in the event that
      the Issuer shall offer options or rights to subscribe for shares of Common
      Stock, or issue any Common Stock Equivalents, to all of its holders of
      Common Stock, then on the record date for such payment, distribution or
      offer or, in the absence of a record date, on the date of such payment,
      distribution or offer, the Holder shall receive what the Holder would have
      received had it exercised this Warrant in full immediately prior to the
      record date of such payment, distribution or offer or, in the absence of a
      record date, immediately prior to the date of such payment, distribution
      or offer.

      (e) Other Provisions Applicable to Adjustments Under this Section 5. The
following provisions shall be applicable to the making of adjustments in the
Warrant Price hereinbefore provided in Section 4. The number of shares of Common
Stock at any time outstanding shall (A) not include any shares thereof then
directly or indirectly owned or held by or for the account of the Issuer or any
of its Subsidiaries, and (B) be deemed to include all shares of Common Stock
then issuable upon conversion, exercise or exchange of any then outstanding
Common Stock Equivalents or any other evidences of indebtedness, shares of
Capital Stock (including, without limitation, the Preferred Stock) or other
Securities which are or may be at any time convertible into or exchangeable for
shares of Common Stock or Other Common Stock.

      (f) Other Action Affecting Common Stock. In case after the Original Issue
Date the Issuer shall take any action affecting its Common Stock, other than an
action described in any of the foregoing subsections (a) through (d) of this
Section 5, then the Warrant Price shall be adjusted in such manner and at such
time as the Board may in good faith determine to be equitable in the
circumstances.

      (g) Adjustment of Warrant Share Number. Upon each adjustment in the
Warrant Price pursuant to the provisions (b) and (c)(i) of this Section 5, the
Warrant Share Number shall be adjusted, to the nearest one hundredth of a whole
share, to the product obtained by multiplying the Warrant Share Number
immediately prior to such adjustment in the Warrant Price by a fraction, the
numerator of which shall be the Warrant Price immediately before giving effect
to such adjustment and the denominator of which shall be the Warrant Price
immediately after giving effect to such adjustment. If the Issuer shall be in
default under any provision contained in Section 3 of this Warrant so that
shares issued at the Warrant Price adjusted in accordance with this Section 4
would not be validly issued, the adjustment of the Warrant Share Number provided
for in the foregoing sentence shall nonetheless be made and the Holder of this
Warrant shall be entitled to purchase such greater number of shares at the
lowest price at which


                                       6
<PAGE>

such shares may then be validly issued under applicable law. Such exercise shall
not constitute a waiver of any claim arising against the Issuer by reason of its
default under Section 3 of this Warrant.

      (h) Form of Warrant after Adjustments. The form of this Warrant need not
be changed because of any adjustments in the Warrant Price or the number and
kind of Securities purchasable upon the exercise of this Warrant.

      (i) Continuation of Terms. Upon any reorganization, consolidation, merger
or transfer (and any dissolution following any transfer) referred to in this
section 5, this Warrant shall continue in full force and effect and the terms
hereof shall be applicable to the shares of stock and other securities and
property receivable on the exercise of this Warrant after the consummation of
such reorganization, consolidation, or merger or the effective date of
dissolution following any such transfer, as the case may be, and shall be
binding upon the issuer of any such stock or other securities, including, in the
case of any such transfer, the person acquiring all or substantially all of the
properties or assets of the Company, whether or not such person shall have
expressly assumed the terms of this Warrant.

      6. Notice of Adjustments. Whenever the Warrant Price or Warrant Share
Number shall be adjusted pursuant to Section 5 hereof (for purposes of this
Section 6, each an "adjustment"), the Issuer shall cause its Chief Financial
Officer to prepare and execute a certificate setting forth, in reasonable
detail, the event requiring the adjustment, the amount of the adjustment, the
method by which such adjustment was calculated (including a description of the
basis on which the Board made any determination hereunder), and the Warrant
Price and Warrant Share Number after giving effect to such adjustment, and shall
cause copies of such certificate to be delivered to the Holder of this Warrant
promptly after each adjustment. Any dispute between the Issuer and the Holder of
this Warrant with respect to the matters set forth in such certificate may at

Kfar Saba, Israel

      Re: Registration Statement on Form S-1

Gentlemen:

      As counsel to TTR Technologies, Inc. (the "Company"), we have assisted in
the preparation of a Registration Statement on Form S-1 (together with all
exhibits thereto and documents incorporated by reference therein, the
"Registration Statement") in the form proposed to be filed with the Securities
and Exchange Commission (the "Commission"). The Registration Statement relates
to the sale from time to time, pursuant to Rule 415 of the General Rules and
Regulations promulgated under the Securities Act of 1933, as amended (the
"Securities Act"), of up to 10,423,504 shares of Common Stock, par value $.001
per share ("Common Shares"), of the Company.

      This opinion is being delivered in accordance with the requirements of
Item 601(b)(5) of Regulation S-K promulgated under the Securities Act.

      In connection with the opinions expressed herein, we have examined the
originals or copies, certified or otherwise identified to our satisfaction, of
such records, instruments, documents and matters of law as we have deemed
necessary or appropriate for the purpose of rendering this opinion.

      In our examination, we have assumed without independent verification (i)
the legal capacity of all natural persons, (ii) the genuineness of all
signatures, (iii) the authenticity of all documents submitted to us as
originals, (iv) the conformity to original documents of all documents submitted
to us as certified, conformed or photostatic copies and the authenticity of the
originals of such documents, and (v) the power and authority of all persons
other than the Company signing such documents to execute, deliver and perform
such documents, and the valid authorization, execution and delivery of such
documents by such other persons. As to any facts material to the opinions
expressed herein which were not independently established or verified, we have
relied upon oral or written statements and representations of officers or other
representatives of the Company.

      Sales of an aggregate of 3,881,299 Common Shares covered by the
Registration Statement were covered in the Company's Registration Statement on
Form SB-2 (Registration No. 333-85085)(the "October 1999 Registration
Statement"). Pursuant to Rule 429 of the General Rules and Regulations
promulgated under the Securities Act, the Registration Statement constitutes
Post-Effective Amendment No. 1 to the October 1999 Registration Statement. An
opinion regarding such Common Shares was filed as an exhibit to the October 1999
Registration Statement. No opinion regarding such Common Shares is given herein.

      The remaining 6,587,206 Common Shares covered in the Registration
Statement (the "Remaining Common Shares") consist of:

      (a)   an aggregate of 4,722,206 currently outstanding Common Shares held
            by certain selling stockholders, and

      (b)   an aggregate of 1,865,000 Common Shares issuable upon exercise of
            warrants to purchase such Common Shares held by certain selling
            stockholders.

      We also have assumed that (i) the Registration Statement, and any
amendments thereto (including post-effective amendments), including the form of
prospectus included therein (as supplemented, the "Prospectus"), will have
become effective under the Securities Act, and the Remaining Common Shares will
be issued and sold in compliance with applicable federal and state securities
laws and solely in the manner stated in the Registration Statement and the
Prospectus.

      We are admitted to practice in the State of New York and we do not express
any opinion as to the laws of any other jurisdiction other than the federal laws
of the United States of America and the General Corporation Law of the State of
Delaware to the extent necessary to render this opinion. The Remaining Common
Shares may be issued and sold from time to time on a delayed or continuous
basis, and this opinion is limited to the laws, including applicable rules and
regulations, in effect on the date hereof, and to the facts in existence on the
date hereof. We assume no obligation to update such opinion.

      Based upon and subject to the foregoing, and our examination of law and
such other matters as we have deemed relevant under the circumstances, it is our
opinion that the Remaining Common Shares, when duly issued and sold in the
manner and for the consideration contemplated by the Registration Statement and
the Prospectus, will be legally issued, fully paid and non-assessable.

      We hereby consent to the reference to our firm in the Registration
Statement under the Prospectus caption "Legal Matters" and to the filing of this
opinion with the Commission as an

<PAGE>

exhibit to the Registration Statement. In giving this consent, we do not hereby
admit that we come within the category of persons whose consent is required
under Section 7 of the Securities Act or the rules or regulations of the
Commission.

                                     Very truly yours,

                                       5
<PAGE>

      1.1 This Warrant may be exercised in whole at any time commencing 9:00
      a.m., New York City time, on any business day on or after the issuance
      thereof and continuing up to the third anniversary thereof (the "Warrant
      Period"), by the surrender of this Warrant (with a duly executed exercise
      form in the form attached at the end hereof as Exhibit A) at the principal
      office of the Company, together with the proper payment of the Per Share
      Warrant Price times the number of Warrant Shares.

      1.2 Upon such surrender of this Warrant, the Company will: a) issue a
certificate or certificates in the name of Holder for the Warrant Shares to
which the Holder shall be entitled and (b) deliver the other securities and
properties receivable upon the exercise of this Warrant, pursuant to the
provisions of this Warrant.

      1.3 Any stamp tax attributable to the issuance of the Shares shall be
      borne solely by Holder.

      1.4 Unless there is an effective registration statement under the
      Securities Act of 1933, as amended, (the "Securities Act") covering the
      resale of the Warrant Shares, at the option of the Holder, in lieu of
      exercising this Warrant in the manner provided in Subsection 1.1 above,
      the Holder may elect, pursuant to the terms of this Subsection 1.1, to
      receive Shares equal to the value of this Warrant (taking into account
      only that portion of this Warrant that is then exercisable) by surrender
      of this Warrant at the principal office of the Company together with
      notice of such election in which event the Company shall issue to the
      Holder a number of Shares using the following formula:

                                  X = Y(A-B)
                                      ------
                                         A

where X = The number of Shares to be issued to the Holder.

      Y = The number of Shares purchasable under this Warrant (at the date of
such calculation).

      A = The fair market value of one Share (at the date of such calculation).

      B = The Per Share Warrant Purchase Price.

2. Representations and Warranties

      The Holder (i) represents, warrants, covenants and agrees that the Warrant
      and the underlying Warrant Shares are being acquired by the Holder for the
      Holder's own account, for investment purposes only, and not with a view to
      or for the sale in connection with any distribution thereof or with any
      present intention of selling or distributing all or any part of the
      Warrant or the Warrant Shares; (ii) understands (x) that


                                       6
<PAGE>

      if it should thereafter decide to dispose of such Warrant or Warrant
      Shares (which it does not contemplate at such time) it may do so only in
      compliance with the Securities Act, (y) this Warrant and the Warrant
      Shares are not registered under the Securities Act; and (iii) acknowledges
      that, as of the date hereof, it has been given a full opportunity to ask
      questions of and to receive answers from the Company concerning this
      Warrant and the Warrant Shares and the business of the Company and to
      obtain such information as it desired in order to evaluate the acquisition
      of this Warrant and the Warrant Shares, and all questions have been
      answered to its full satisfaction.

3. Reservation of Shares

      The Company covenants that at all times during the Warrant Period it shall
      have authorized and in reserve, and will keep available solely for
      issuance or delivery upon exercise of the Warrant, the Warrant Shares and
      other securities and properties as from time to time shall be receivable
      upon the exercise of this Warrant, free and clear of preemptive rights and
      restrictions on sale or transfer except as otherwise set forth herein or
      in the By-Laws.

4. Registration Rights

      The Holder acknowledges that there exists an effective Company
      registration statement filed under the Securities Act on or about October
      4, 1999 [Registration No. 333-85085] (the "Filed Registration Statement"),
      which Filed Registration Statement inludes certain securities (other than
      the Warrant Shares) held by the Holder. The Holder further acknowledges
      that the Filed Registration Statement was filed pursuant to the terms of a
      Registration Rights Agreement, dated as May 13, 1999, between the Company
      and the Initial Investors named therein (the "Initial Investors"). The
      Company will explore the option of amending the Filed Registration
      Statement to include the Warrant Shares, subject to the Holder executing a
      lock-up agreement in substantailly the same form as previously signed by
      Biscount.

      In the event that the Company does not for whatever reason amend the Filed
      Registation Statement to include the Warrant Shares, then if the Company
      shall file a registration statement for any shares of its Common Stock, it
      shall include in the registration statement relating thereto the Warrant
      Shares, except that where such registration statement was filed on behalf
      of a shareholder or a rights holder, such inclusion shall be with the
      consent of such shareholder or rightsholder. In the event that such
      registration offering involves an underwriting, the rights of the Holder
      to have the Warrant Shares included in such registration statement shall
      be conditional upon the underwriter's determination as to the marketing
      factors requiring limitation of such right, and the underwriter may
      preclude any or all securities of the Holder which could have otherwise
      been included in such offering.


                                       7
<PAGE>

5. Adjustment

      5.1 In case prior to the expiration of this Warrant by exercise or by its
      terms the Company shall issue any shares of its Common Stock as a stock
      dividend or subdivide the number of outstanding shares of Common Stock
      into a greater number of shares by a stock split or a similar transaction,
      then, in either of such cases, the Exercise Price per share of the Warrant
      Shares purchasable pursuant to this Warrant in effect at the time of such
      action shall be proportionately reduced and the number of Warrant Shares
      purchasable at that time shall be proportionately increased; and,
      conversely, in the event the Company shall contract the number of
      outstanding shares of Common Stock by combining such shares into a smaller
      number of shares by a reverse split or similar transaction, then, in such
      case, the Exercise Price per share of the Warrant Shares purchasable
      pursuant to this Warrant shall be proportionately increased and the number
      of Warrant Shares purchaseable at that time shall be propotionately
      reduced. Any dividend paid or distributed upon the Common Stock in stock
      of any other class of securities convertible into shares of Common Stock
      shall be treated as a dividend paid in Common Stock to the extent that
      shares of Common Stock are issuable upon conversion thereof.

      5.2 In case of any consolidation or merger of the Company with or into
      another corporation (other than a merger or consolidation in which the
      Company is the surviving or the continuing corporation) or in the case of
      any sale or conveyance to another corporation or other entity of the
      property, assets or business of the Company as an entirety or
      substantially as an entirety, in any such case, the Company or such
      successor or purchasing corporation or entity, as the case may be, shall
      (i) execute with the Holder an agreement that the Holder shall have the
      right thereafter to receive upon the exercise of the Warrant the kind and
      amount of shares and/or other securities or other property which he would
      have owned or have been entitled to receive after the happening of such
      consolidation, merger, sale or conveyance had the Warrant been exercised
      immediately prior to such action, (ii) make effective provision in its
      certificate of its incorporation or otherwise, if necessary, in order to
      effect such agreement, and (iii) set aside or reserve for the benefit of
      the Holder, the stock, securities, property and cash to which the Holder
      would be entitled to upon exercise of this Warrant.

      5.3 In case of any reclassification or change of the Warrant Shares
      issuable upon exercise of this Warrant (other than a change in par value
      or from no par value to a specific par value, or as a result of a
      subdivision or combination, including any change in the shares into two or
      more classes or series of shares), or in the case of any consolidation or
      merger of another corporation into the Company in which the Company is the
      continuing corporation and in which there is a reclassification or change
      (including a change in the right to receive cash or other property) of the
      Shares (other than a change in the par value, or from no par


                                       8
<PAGE>

      value to a specific par value or, as a result of a subdivision or
      combination, including any change in the shares into two or more classes
      or series of shares), Holder shall have the right thereafter to receive
      upon exercise of this Warrant solely the kind and amount of shares of
      stock and other securities, property, cash or combination thereof
      receivable upon such reclassification, change, consolidation or merger by
      a holder of the number of Shares for which this Warrant might have been
      exercised immediately prior to such reclassification, change,
      consolidation or merger.

      5.4 The above provisions of this paragraph 5 shall similarly apply to
      successive reclassifications and changes of Shares and to successive
      consolidations, sales, leases or conveyances.

6. Limited Transfer

      (a) This Warrant may not be sold, transferred, assigned or hypothecated by
the Holder except in a transation exempt from registration under the Securities
Act and any applicable state securities laws, and is so transferable only on the
books of the Company which the Company shall cause to be maintained for such
purpose. The Company may treat the registered holder of record as the Holder for
all purposes. The Company may require the Holder to provide the Company with an

as to such exemption. The Company shall permit any holder of a Warrant or his
duly authorized attorney, upon written request during ordinary business hours,

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.

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

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

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.

      3. REPRESENTATIONS AND WARRANTIES OF THE INVESTOR.

      The Investor hereby represents and warrants that:


                                       11
<PAGE>

            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
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


                                       12
<PAGE>

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

conduct its business in the ordinary course and consistent in all material
respects with past practice, except as may be required or contemplated in this

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

the transactions contemplated hereby.


                                       13
<PAGE>

            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

            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, 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.

                  (i) The Company hereby grants to the Investor the preemptive

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


                                       15
<PAGE>

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 such New Securities
for the price and upon the general terms 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

and issue the New Securities, including any such Pro Rata Share not purchased by
the Investor, to any third 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

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

(it being agreed that the same prior notice given to the Board of Directors
shall be deemed reasonable prior notice) in any manner permitted in the
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 meeting or, if a meeting is held by telephone conference,
to participate therein for the purpose of listening thereto.

            4.8 Registration of Shares. The Company covenants and agrees that it
shall promptly after the Closing prepare and file, at its cost and expense, a
registration statement on Form S-1 (or such other appropriate form) covering the

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

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


                                       16
<PAGE>

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

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.

the Agreement unless otherwise specifically provided herein.

      In rendering the opinions set forth below I have examined such documents
and have reviewed such questions of law as I have considered necessary or

matters dated prior to or on the date hereof upon which I have relied are and
remain accurate, adequate and complete on and as of the date hereof; and each
natural person signing a document is a competent adult person of sound mind not
operating under any legal disability, duress or fraud.

      2. The Agreement accurately reflects all of the terms, provisions and
conditions of the transactions contemplated thereby and the intent of the

conduct among the parties thereto which would modify the terms of the Agreement
or the respective rights or obligation of the parties thereunder.


                                       28
<PAGE>

      3. All of the factual representations made by Company and the Investor in
the Agreement are true and correct. As to questions of fact material to this
opinion, we have relied upon and assumed the accuracy of, without any
independent investigation on our part, certain representations made by the
Company and such other facts as are actually known to us.

      4. The Agreement will be enforced and performed in good faith and in a
commercially reasonable manner.

      5. The conduct of all parties to the Agreement conforms, and in the future

Investor and Investor has the power and authority (corporate or otherwise) to
execute and deliver the Agreement.

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

      1. The Company is a corporation duly incorporated, validly existing and in
good standing under the laws of the State of Delaware, with the corporate power
to own its properties and conduct its business as now conducted. The Company has
the corporate power to execute, deliver and perform the Agreement, including
without limitation, the issuance and sale of the Shares. The Agreement has been
duly authorized by all requisite corporate action, executed and delivered by the
Company. The Agreement constitutes a valid and binding agreement of the Company

Bankruptcy Code and comparable provisions of state law; and (b) the effect of
general principles of equity, including, without limitation, concepts of
materiality, reasonableness, good faith and fair dealing, the possible
unavailability of specific performance or injunctive relief, regardless of
whether considered in a proceeding in equity or at law, and the exercise of
judicial discretion in appropriate cases.

      2. The Shares, when issued in compliance with the provisions of the
Agreement, will be duly authorized and validly issued and fully paid and

<PAGE>

      4. The execution, delivery and performance of the Agreement and the
issuance and sale of the Shares in accordance with the Agreement will not
violate or conflict with, or result in a breach of or default under, the
Certificate of Incorporation, as amended or By-laws, as amended of the Company.

      5. To our knowledge there is no action, suit, proceeding or investigation
pending against the Company before any court or governmental agency (I) that
questions the validity of the Agreement or the right of the Company to enter
into the Agreement or (ii) that, if determined adversely, would be likely to
result in a Material Adverse Effect on the financial condition or business of
the Company.

            This opinion is limited to the general corporate laws of the State
of Delaware (excluding municipal, county and local ordinances and regulations)
without reference to conflict of law principles, and the federal laws of the
United States of America, and to present judicial interpretations thereof, and
to facts as they presently exist, and we express no opinion with respect to any
other law or the law of any other jurisdiction. In rendering this opinion, we
have no obligation to revise or supplement it should the current laws of the
State of Delaware, or the federal laws of the United States of America be
changed by legislative action, judicial decision or otherwise.

no understanding, expressed or implied, of a commitment on HCW's part to
underwrite, purchase or place the Securities.

      It is understood that HCW is being engaged solely to provide the services
described in this Agreement to the Company and that HCW is not acting as an
agent or fiduciary of, and shall have no duties or liabilities to, the equity
holders of the Company or any third party in connection with its engagement.

      During the Authorization Period, TTR shall not, and shall not permit its
affiliates or its or their officers, directors, employees or representatives to,
directly or indirectly, (i) offer any Securities for sale to, or solicit any
offer to purchase any Securities from, or otherwise contact, discuss or
negotiate with respect to any offer or sale of any Securities with, any person,
(ii) authorize anyone other than HCW to act on behalf of the Company to place
any Securities or (iii) have any discussions or negotiations with
<PAGE>

any person other than HCW with respect to engaging such person as a finder,
broker, dealer, agent or financial advisor in connection with any sale of
Securities. TTR shall, and shall cause its affiliates and its and their
officers, directors, employees and representatives to, promptly refer to HCW all
offers, inquiries and proposals relating to any Securities received at any time
during the Authorization Period.

      2. Authorization Period. HCW's engagement shall become effective on the
date hereof and, unless extended in writing by TTR and HCW, shall expire on the
earlier of (i) the final closing date of the Private Placement or (ii) 120 days
from the data hereof, (in either case, the "Termination Date"). The period from
the date hereof through the Termination Date is called the "Authorization
Period."

      3. Offering Documents. TTR, with the assistance of HCW, shall prepare a
Confidential Offering Memorandum, and such amendments or supplements thereto as
HCW may reasonably deem to be necessary, to effectuate sales of Securities. The
Confidential Offering Memorandum, and any such amendments or supplements, are
collectively called the "Offering Materials." TTR authorizes HCW to transmit the
Offering Materials to potential purchasers of Securities, and shall furnish to
HCW copies of the Offering Materials in such quantities as HCW may from time to
time reasonably request. TTR shall prepare forms of necessary and appropriate
purchase, subscription and other agreements and documents, containing terms and
conditions customary for private placements, to be entered into by the Company
and purchasers of Securities (collectively called "definitive documents"), which
forms shall be provided to prospective purchasers only upon the review and
approval of both the Company and HCW.

      4. Compensation. TTR shall pay HCW the compensation set forth below:

            a. Fees. TTR shall pay HCW a retainer fee of $25,000 and 10,000
shares of TTR restricted common stock (valued at $5 per share for purpose of
this agreement), which is payable promptly upon execution of this Agreement, and
a placement fee equal to 5.0% of the Aggregate Consideration (as defined below)
received or receivable directly or indirectly by the Company in connection with
the Private Placement, which is payable in cash on the closing date on which
such Aggregate Consideration is paid or becomes payable. The retainer fee shall
be credited against the placement fee.

            "Aggregate Consideration" shall include the total value of
Securities sold, including all amounts paid in escrow or payable in the future
(in each case, whether or not subject to any contingency in connection
therewith) and all amounts paid or payable upon exercise, conversion or exchange
of Securities.

            If Aggregate Consideration is paid in whole or in part in the form
of securities or other noncash consideration, such consideration shall be valued
at the fair market value thereof on the day prior to the relevant closing date;
provided, however, that to the extent that such consideration consists of
securities with an existing public trading market, such consideration shall be
valued at the average of the last sales price for such securities on the five
trading days prior to the relevant closing date.

            b. Warrants. On each closing date on which Aggregate Consideration
is paid or becomes payable, TTR shall or shall cause the issuer of Securities
(if other than TTR) to issue to HCW
<PAGE>

or its assigns warrants (the "Warrants") to purchase 10% of the amount of
Securities issued to purchasers, or, upon mutual agreement of HCW and TTR, the
equity equivalent thereof. The exercise price of the Warrants shall equal the
average price (to any purchaser) at which any common equity of the Company is or
may be sold in the Private Placement or upon the conversion, exercise or
exchange of Securities. The Warrants shall be exercisable immediately after the
date of issuance and shall expire five years after the date of issuance, unless
otherwise extended by the Company. The Warrants shall include customary
anti-dilution protection, including protection against issuances of securities
at prices (or with exercise prices, in the case of warrants, options or rights)
below the lower of the exercise price of the Warrants or the then fair market
value of the underlying common equity, a cashless exercise provision and provide
for automatic exercise upon expiration. At the request of the Company, assuming
there is an effective registration statement for the common shares underlying
the warrants, HCW or its assigns will execute the warrants for cash The Warrants
shall also include one demand registration right exercisable following the first
anniversary of the closing subject to a 60 day notice requirement, and unlimited
piggyback registration rights, in each case customary in transactions of this
type. The Warrants shall be transferable within HCW at HCW's discretion.

            c. Tail Period. TTR shall and shall cause its affiliates to, pay to
HCW all compensation described in this Section 4 with respect to all Securities
sold to a purchaser or purchasers at any time prior to the expiration of one
year after the Termination Date (the "Tail Period") if (i) such purchaser or
purchasers were identified to the Company by HCW during the Authorization
Period, (ii) HCW advised the Company with respect to such purchaser or
purchasers during the Authorization Period or (iii) the Company or HCW had
discussions with such purchaser or purchasers during the Authorization Period.

            d. Other Terms. If the Company fails through no fault of the Company
to complete a sale of Securities to one or more purchasers whose offer or offers
in respect thereof the Company shall have accepted, TTR(i) shall hold HCW
harmless against any loss, liability, expense, claim or damage arising from such
failure and (ii) shall pay to HCW all compensation to which HCW would be
entitled hereunder in connection therewith if such sale had been consummated.

            HCW shall be entitled to its full compensation under this Section 4
regardless of the structure of the Private Placement or sale of Securities.
Accordingly, Section 4 shall apply to any sale of debt or equity securities by,
or any other investment in, any affiliate of TTR and regardless of the terms and
conditions thereof. Likewise, for purposes of this Agreement, the word
"affiliate", when used with respect to TTR or the Company, shall include
subsidiaries, parents, stockholders and sister companies, the word "purchaser"
shall include investors, partners, co-venturers and members. Additionally, any
parties introduced to the Company during the Tail Period, by a party contacted
by HCW during the Authorization period will be deemed to have been contacted
during the Authoriztion period. If such structure does not consist solely of a
sale of common stock of TTR, appropriate adjustments shall be made to the terms
and conditions of the Warrants so that HCW receives the full benefit intended to
be afforded by Section 4(b).

      5. Expenses. Regardless of whether the Private Placement or sale of
Securities is consummated, TTR will pay or cause to be paid the Company's
expenses in connection herewith and
<PAGE>

therewith, including: (i) the fees and disbursements of the Company's counsel,
accountants and other representatives and advisers; (ii) the expenses in
connection with the preparation, printing and distribution of the Offering
Materials, definitive agreements and other documents in connection herewith and
therewith; (iii) the expenses in connection with the qualification of Securities
for offering and sale under Blue Sky Laws, including filing fees and fees and
disbursements of counsel for HCW in connection with reviewing applicable Blue
Sky Laws and preparing filings thereunder not to exceed $20,000; (iv) the costs
of preparing certificates representing Securities; (v) the charges of any escrow
agent, transfer agent or registrar; and (vi) all other costs and expenses
incident to the performance of the Company's obligations hereunder and under
definitive agreements (including, without limitation, any taxes payable in
connection with the issuance, sale and delivery of the Securities).

      6. Reimbursements. Regardless of whether the Private Placement or sale of
Securities is consummated, the Company shall reimburse HCW, upon request made
from time to time, for all of its reasonable out-of-pocket expenses, not to
exceed $10,000, without the written consent of TTR, incurred in connection with
its engagement and the expenses of any travel that may be necessary.

      7. Escrow Account. All proceeds from sales of Securities shall be
deposited in a non-interest bearing escrow account pending the sale of $2
million minimum of Securities. Upon the sale of such minimum amount, there shall
be a first closing of the Private Placement (the "First Closing"). From the date
of the First Closing, all proceeds from further sales of Securities will
continue to be deposited in the escrow account and there shall be a subsequent
closing on the earlier of the sale of the maximum amount of Securities
(cumulative with the amount of Securities sold through the First Closing) or the
Termination Date. HCW will appoint a bank chartered in the State of New York as
the escrow agent. Such appointment will be subject to approval by TTR, which
approval shall not be unreasonably withheld. All fees and expense reimbursements
due to HCW shall be paid out of the proceeds held in the escrow account at each
such closing. The escrow agreement with such bank shall contain provisions
giving effect to this Section 7.

      8. Representations, Warranties and Covenants of TTR. TTR represents and
warrants to, and covenants with, HCW as follows:

            a. During the Authorization Period, TTR shall not, and shall not
permit its affiliates to, use, disseminate, publish, distribute or refer to any
materials in connection with any offering of Securities, including any Offering
Materials, without HCW's prior consent, except for internal use among the
Company's personnel and representatives.

            b. Neither the Company nor any person acting on its behalf has
taken, and TTR shall not and shall not permit its affiliates to take, directly
or indirectly, any action so as to cause any of the transactions contemplated by
this Agreement to fail to be entitled to exemption from registration or
qualification under all applicable securities laws or which constitutes general
advertising or general solicitation (as those terms are used in Regulation D
under the Securities Act) with respect to the Securities.

            c. TTR shall, and shall cause its affiliates to, from time to time,
take such action as HCW may reasonably request to qualify Securities for
offering and sale as a private placement under the
<PAGE>

securities laws of such states or other jurisdictions as HCW may reasonably
request and to comply with such laws so as to permit such offers and sales.

            d. TTR shall, and shall cause its affiliates to, make available to
HCW, or have professionally prepared at the Company's expense, all financial
statements, projections, appraisals, surveys and other information which in
HCW's reasonable judgment shall be necessary or appropriate for the proper
marketing of Securities. TTR shall, and shall cause its affiliates to, upon
reasonable request, cause the Company's directors, officers, personnel, counsel,
accountants and other representatives to meet with HCW or its representatives to
discuss all information relevant for disclosure in any Offering Materials and to
cooperate in any reasonable investigation requested by HCW or its
representatives (including the production of information at the Company's
offices or copies of such information at the offices of HCW and its counsel) for
the purpose of confirming the accuracy and completeness of statements contained
in the Offering Materials.

            e. The Offering Materials as of the date thereof and as of the
closing date of each sale of Securities will be complete and correct in all
material respects and will not contain any untrue statement of a material fact
or omit to state a material fact required to be stated therein or necessary to
make the statements contained therein, in light of the circumstances under which
they were made, not misleading. TTR shall advise HCW immediately of the
occurrence of any event or circumstance which results in the Offering Materials
containing an untrue statement of a material fact or omitting to state a
material fact required to be stated therein or necessary to make the statements
contained therein, in light of the circumstances under which they were made, not
misleading, and shall furnish to HCW copies of amended or supplemented Offering
Materials that correct such statement or omission in such quantities as HCW may
from time to time reasonably request. All financial or other projections
included in the Offering Materials will be prepared in good faith on the basis
of reasonable assumptions. TTR acknowledges that HCW (i) will be using and
relying primarily on the information in the Offering Materials and information
available from generally recognized public sources in performing the services
contemplated hereunder without having independently verified the same, (ii) does
not assume responsibility for the accuracy or completeness of such information
or of the Offering Materials and (iii) will not make any appraisal of any assets
of the Company.

obligations hereunder, and all consents, authorizations, approvals and orders
required in connection with the execution, delivery and performance hereof have
been obtained. This Agreement is a valid and binding obligation of the Company,
enforceable in accordance with its terms, except to the extent that the
enforceability may be limited by bankruptcy, insolvency, reorganization,
moratorium or similar laws affecting creditors generally and general principles
of equity. The execution, delivery and performance of this Agreement will not
conflict with, result in a breach of any of the terms or provisions of or
constitute a violation or a default under any material agreement or instrument
to which the Company is a party or by which the Company is bound.

            g. TTR shall take and shall cause its affiliates to take such
actions as may be required to cause compliance with Section 8(h) and 11. HCW
acknowledges that TTR may cause its affiliates to perform any of its obligations
hereunder; provided, however, that TTR's intention to do so
<PAGE>

(or any action by TTR or HCW in respect thereof) shall not relieve TTR from its
obligation to perform such obligations when due.

            h. TTR shall cause counsel to the Company to deliver, at each
closing of the Private Placement, an opinion, addressed to HCW and to
purchasers, covering such matters as are typically covered in opinions delivered
in connection with private placements (including, an opinion to the effect that
the Private Placement is exempt from registration under the Securities Act), in
form and substance reasonably acceptable to HCW and its counsel. TTR shall also
cause to be furnished to HCW, at each closing of the Private Placement, (i)
copies of all other legal opinions, "comfort" letters, certificates, agreements
and other documents furnished to purchasers on such closing date and (ii) copies
of all filings made by the Company with the Securities and Exchange Commission

                             SUBSCRIPTION AGREEMENT

February 18, 2000

TTR Technologies, Inc.                    TTR Technologies, Ltd.
67 Wall St., Suite 2411                   2 Hanagar Street
New York, NY  10023                       Kfar Sava
                                          44425, Israel
Ladies and Gentlemen:

1)    The undersigned hereby tenders this subscription and applies for the
      purchase of the number of shares of Common Stock of the Company (the
      "Shares") set forth on the signature page of this agreement, at a purchase
      price of $5.56 per Share. For every 180,000 shares of the Common Stock
      (the "Common Stock"), investors shall receive 90,000 Class A Warrants (the
      "Warrants") to purchase 90,000 Shares of Common Stock at an exercise price
      of $7.50 per share. The minimum purchase is 180,000 shares ($1,000,000),
      provided, however, that less amount may be purchased in the discretion of
      the Company. Together with this Subscription Agreement, the undersigned is
      delivering to the Company, a check payable to "U.S. TRUST COMPANY OF NEW
      YORK, AS ESCROW AGENT FOR TTR TECHNOLOGIES, INC." in the full amount of
      the purchase price for the Shares which the undersigned is subscribing for
      pursuant hereto or funds by wire transfer as instructed by the Company.

      The Shares and Warrants to be purchased by the undersigned are part of a
      private placement of securities (the "Private Placement") of up to
      1,800,000 Shares and 900,000 Warrants. The Common Stock will be offered by
      the Company on a "best efforts all or none" basis as to the Minimum
      Offering of $7,000,000 and thereafter on a "best efforts" basis up to the
      Maximum Offering of $10,000,000. There is a minimum number of 1,260,000
      Shares that must be sold in order for the Private Placement to become
      effective. If all the Shares are sold, the Company will receive an
      aggregate of ten million ($10,000,000) less the expenses of the Private
      Placement, which management estimates will be approximately six hundred
      thousand ($600,000).

2)    Representations and Warranties. In order to induce the Company to accept
      this subscription, the undersigned hereby represents and warrants to, and
      covenants with, the Company as follows:

      (a)   The undersigned has received and reviewed the Offering Materials,
            and except for the Offering Materials, the undersigned has not
            relied upon any other materials or literature relating to the offer
            and sale of the Shares;

      (b)   The undersigned has had a reasonable opportunity to ask questions of
            and receive answers from the Company concerning the Company and the
            offering, and all such questions, if any, have been answered to the
            full satisfaction of the undersigned;

<PAGE>

      (c)   The undersigned has such knowledge and expertise in financial and
            business matters that the undersigned is capable of evaluating the
            merits and risks involved in an investment in the Shares

      (d)   The information provided by the investor in this Subscription
            Agreement being delivered by the undersigned to the Company herewith
            is true, complete and correct in all material respects, and the
            undersigned understands that the Company has determined that the
            exemption from the registration provisions of the Securities Act of
            1933, as amended (the "Act"), which is based upon non-public
            offerings is applicable to the offer and sale of the Shares, based,
            in part, upon the representations, warranties and agreements made by
            the undersigned herein ;

      (e)   Except as set forth in the Offering Materials, no representations or
            warranties have been made to the undersigned by the Company or by
            any agent, employee, or affiliate of the Company, and in entering
            into this transaction the undersigned is not relying upon any
            information, other than that contained in the Offering Materials and
            the results of independent investigation by the undersigned;

      (f)   The undersigned understands that: (A) the Shares have not been
            registered under the Act or the securities laws of any state, and
            are being offered by the Company based upon an exemption from such
            registration requirements for non-public offerings pursuant to
            Regulation D under the Act; (B) the Shares are and will be
            "restricted securities", as said term is defined in Rule 144 of the
            Rules and Regulations promulgated under the Act; (C) the Shares may
            not be sold or otherwise transferred unless they have been first
            registered under the Act and all applicable state securities laws,
            or unless exemptions from such registration provisions are available
            with respect to said resale or transfer; (D) other than as set forth
            in the Offering Materials, the Company is under no obligation to
            register the Shares under the Act or any state securities laws, or
            to take any action to make any exemption from any such registration
            provisions available; (E) the certificates for the Shares will bear
            a legend to the effect that the transfer of the securities
            represented thereby is subject to the provisions hereof; and (F)
            stop transfer instructions will be placed with the Company's
            transfer agent, if any, for the Shares.

      (g)   The undersigned is acquiring the Shares solely for the account of
            the undersigned, for investment purposes only, and not with a view
            towards their resale or distribution;

      (h)   The undersigned will not sell or otherwise transfer any of the
            Shares unless and until: (A) said Shares, shall have first been
            registered under the Act and all applicable state securities laws;
            or (B) the undersigned shall have first delivered to the Company a
            written opinion of counsel (which counsel and opinion (in form and
            substance) shall be reasonably satisfactory to the Company), to the
            effect that the proposed sale or transfer is exempt from the
            registration provisions of the Act and all applicable state
            securities laws;

      (i)   The undersigned has full power and authority to execute and deliver
            this Subscription Agreement and to perform its obligations
            hereunder, and this Subscription Agreement is a legally binding
            obligation of the undersigned in accordance with its terms;

            be purchased by anyone who cannot afford the loss of his entire
            investment;

                                  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 solely
      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
      solely responsible for promoting and marketing the proposed music
      protection technology or product. Macrovision has the sole 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. Macrovision also has sole
      discretion to determine the naming, branding and pricing for the
      technology. 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 expect that sales through Macrovision will
      account for all 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.


                                        3

      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. 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 other
      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 may need additional financing to continue operating after June, 2001.

      Giving effect to the sale in October 1999 of an additional $500,000 of our
      10% Convertible Debentures; the subsequent conversion into common stock of
      all of the outstanding Debentures and accrued interest; the exercise in
      November 1999 of investors warrants which yielded to us net proceeds of
      approximately $1.325 million; the conversion of approximately $1.32
      million of long-term debt and accrued interest into common stock; and the
      purchase by Macrovision in January 2000 of 1,880,937 shares of our common
      stock for a purchase price of $4 million, we had working capital of
      approximately $4.18 million as of September 30, 1999 on a pro forma basis.
      We are contractually obligated to reimburse Macrovision up to $1 million
      during the year 2000 for their expenses related to the development and
      marketing of the new audio content copy protection technology. In
      addition, we have current payables of approximately $800,000. Based upon
      our current and anticipated rate of expenditures, we believe that unless
      we receive revenues from our licenses to Macrovision, as soon as July 2001
      we may require additional financing or funding by strategic partners in
      order to continue to operate at projected levels. We have no


                                        4
<PAGE>

      commitments for any such financing and there can be no assurance that we
      will obtain additional capital when needed.

      We do not anticipate receiving any funding from commercial lenders. There
      can be no assurance that any additional financing can be obtained on
      favorable terms, if at all. Any additional equity financing may result in
      dilution to our stockholders.

      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.

      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 September 30, 1999, we had an accumulated deficit of
      approximately $15.5 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 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.

      "Going concern" statement in auditor's report may make it difficult to
      raise new capital.

      We have not had any significant revenues to date. As of September 30,
      1999, we had an accumulated deficit of approximately $15.5 million from
      July 14, 1994 (date of inception). The report of the independent auditors
      on our financial statements for the year ended December 31, 1998 includes
      an explanatory paragraph relating to the uncertainty of our ability to
      continue as a going concern, which may make it more difficult for us to
      raise additional capital.

      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


                                        5
<PAGE>

      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 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.


                                        6
<PAGE>

      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 all 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.

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


                                        7
<PAGE>

      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.

      We are subject to risks associated with international operations.


                                        8

      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


                                        9
<PAGE>

      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 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.

      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 3,754,710 shares
      of our common stock (including 1,166,400 options granted under our 1996
      Stock Option Plan, 2,443,310 options and warrants held by selling
      stockholders (of which 2 million warrants have a nominal exercise price
      and the remainder have exercise prices ranging from $1.50 to $7.80 per
      share) and 145,000 options and warrants not held by selling stockholders).
      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 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.

      investment in the Shares results in a total loss. Shares will be sold only
      to prospective investors which are "accredited investors" under Regulation
      D promulgated under the Securities Act. "Accredited Investors" are those
      investors which make certain written representations that evidence the
      investor comes within one of the following categories:

(Initial the appropriate category)

3(a)(5)(A) of the Securities Act, whether acting in its individual or fiduciary
capacity; any broker or dealer registered pursuant to Section 15 of the

SUBSCRIPTION AGREEMENT supplement

                             SUBSCRIPTION AGREEMENT

Section 1, paragraph 1 should read as follows:

1)    The undersigned hereby tenders this subscription and applies for the
      purchase of the number of shares of Common Stock of the Company (the
      "Shares") set forth on the signature page of this agreement, at a purchase
      price of $5.56 per Share. For every 180,000 shares of the Common Stock
      (the "Common Stock"), investors shall receive 90,000 Class A Warrants (the
      "Warrants") to purchase 90,000 Shares of Common Stock with a term of 60
      months at an exercise price equal to the higher of 135% of the purchase
      price of the common shares ($7.50) or 5% above the average closing price
      for the twenty trading days prior to closing, subject to a maximum
      exercise price of $9.00 per share. The Company may redeem the Class A
      Warrants for $.10 per warrant 6 months following issuance if the
      underlying common stock is registered and the Company's common shares have
      traded at or above 200% of the exercise price (the "trigger price") for a
      period of twenty consecutive trading days. Upon exercise of the Class A
      Warrants, the investors will be issued 450,000 Class B warrants with a
      term of 36 months and an exercise price of 120% of the Class A Warrant
      trigger price. The Class B warrants may be redeemed by the Company if the
      underlying common stock is registered and the common shares have traded at
      $26 or above for a period of twenty consecutive trading days.

                                                                   Exhibit 10.48

                          REGISTRATION RIGHTS AGREEMENT

      THIS REGISTRATION RIGHTS AGREEMENT (the "Agreement") is made by and among
TTR Technologies, Inc. (the "Company"), and the investors listed on Schedule I
hereto (collectively, the "Investors" and each an "Investor"), each of whom has
executed a signature page hereto.

                                    RECITALS

I.    The Investors desire to purchase from the Company and the Company desires
      to issue and sell to the Investors Shares of its Common Stock of the
      Company (the "Common Stock"), upon the terms set forth in the Company's
      Subscription Agreement dated February 18, 2000 (the "Agreement").

II.   To induce Investors to purchase Shares, the Company is willing under
      certain circumstances to register under the Securities Act of 1933, as
      amended, and the rules and regulations thereunder (collectively, the
      "Securities Act"), Common Stock underlying the Common Stock to be
      purchased by the Investors.

      NOW THEREFORE, intending to be legally bound, the parties hereto agree as
follows:

1. Required Registrations.

      i)    The Company will include the Registrable Securities in a
            registration statement (the "Automatic Registration Statement")
            which the Company will prepare and file within 45 days after the
            closing of this private placement with the SEC under the Securities
            Act of 1933 and use its best efforts to have declared effective by
            the SEC within 60 days following the closing of this private
            placement so as to permit the public trading of the Registrable
            Securities no later than 90 days following the closing of this
            private placement.

      ii)   If the Company fails to have the registration statement which is
            ultimately used to register the Registrable Securities, declared
            effective by the SEC within 90 days following the Closing Date,
            then, the Company shall continue to use its best efforts to cause
            the SEC to promptly declare the effectiveness of, the Automatic
            Registration Statement so as to permit the public trading of the
            Registrable Securities pursuant thereto.

      iii)  Once the Automatic Registration Statement is declared effective by
            the SEC, the Company will maintain the effectiveness of the
            Automatic Registration Statement until at least the earlier date to
            occur (the "Release Date") of (i) the date that all of the
            Registrable Securities have been sold pursuant to the Automatic
            Registration Statement and (ii) the date that the holders of the
            Registrable Securities receive an opinion of counsel to the Company
            that they may sell their Registrable Securities (without limitation
            or restriction as to quantity or timing and without registration
            under the Act) pursuant to Rule 144(k) of the Act or otherwise. If
            the Company fails to keep the Automatic Registration Statement
            continuously effective

<PAGE>

            during such period, then the Company shall, promptly upon the
            request of the Investors holding at least 50% of the unsold
            Registrable Securities included therein, use its best efforts to
            update the Automatic Registration Statement or file a new
            registration statement covering the unsold Registrable Securities,
            subject to the terms and provisions hereof.

      iv)   The Registration Expenses shall be paid by the Company with respect
            to all registrations effected pursuant to this Section.

2.    Restrictions on Transfer. Notwithstanding the registration of any
      Registrable Securities, each Investor shall not sell or offer to sell any
      Registrable Securities until after the automatic registration has been
      declared effective.

3.    Registration Procedures. In connection with any registration of
      Registrable Securities, the Company shall:

      i)    prepare and file with the Securities and Exchange Commission a
            registration statement on the appropriate form under the Securities
            Act, which form shall be available for the sale of such Registrable
            Securities in accordance with the intended method or methods of
            distribution thereof, and use its commercially reasonable efforts to
            cause such registration statement to become effective (provided that
            before filing a registration statement or prospectus or any
            amendments or supplements thereto, the Company shall furnish to the
            counsel selected by the holders of a majority of the Registrable
            Securities covered by such registration statement copies of all such
            documents proposed to be filed, which documents shall be subject to
            the review and comment of such counsel);

      ii)   notify each holder of Registrable Securities of the effectiveness of
            the registration statement filed hereunder and prepare and file with
            the Securities and Exchange Commission such amendments,
            post-effective amendments and supplements to such registration
            statement and the prospectus used in connection therewith as may be
            necessary or appropriate to keep such registration statement
            effective for the period required for sale of the Registrable
            Securities and cause such prospectus as so supplemented to be filed
            as required under the Securities Act, and comply with the provisions
            of the Securities Act with respect to the disposition of all
            securities covered by such registration statement during such period
            in accordance with the intended methods of disposition by the
            sellers thereof set forth in such registration statement or
            supplement to the prospectus;

      iii)  furnish to each seller of Registrable Securities such number of
            copies of such registration statement, each amendment and supplement
            thereto, the prospectus included in such registration statement
            (including each preliminary prospectus) and such other documents as
            such seller may reasonably request in order to facilitate the
            disposition of the Registrable Securities owned by such seller;

      iv)   use its best efforts to register or qualify such Registrable
            Securities under such other securities or blue sky laws of such
            jurisdictions where such registration or qualification is required
            as any seller reasonably requests and do any and all other' acts and
            things which may be reasonably necessary or advisable to enable such
            seller to consummate the disposition in such jurisdictions of the
            Registrable


                                       2
<PAGE>

            Securities owned by such seller (provided that the Company shall not
            be required to (i) qualify generally to do business in any
            jurisdiction where it would not otherwise be required to qualify but
            for this subparagraph (ii) subject itself to taxation in any such
            jurisdiction or (iii) consent to general service of process in any
            such jurisdiction);

      v)    notify each seller of such Registrable Securities, at any time when
            a prospectus relating thereto is required to be delivered under the
            Securities Act, upon discovery that, or upon the happening of any
            event as a result of which the prospectus included in such
            registration statement as then in effect, contains an untrue
            statement of a material fact or omits any fact necessary to make the
            statements therein not misleading in the light of the circumstances
            under which they were made, and, at the request of any such seller,
            the Company shall prepare a supplement or amendment to such
            prospectus so that, thereafter delivered to the purchasers of such
            Registrable Securities, such prospectus shall not contain an untrue
            statement of a material fact required to be stated therein or omit
            to state any fact necessary to make the statements therein not
            misleading;

      vi)   cause all such Registrable Securities to be listed on each
            securities exchange on which similar securities issued by the
            Company are then listed or traded, and, if not so listed or traded,
            to be listed on the NASD automated quotation system and, if listed
            on the NASD automated quotation system, use commercially reasonable

6.    Indemnification and Contribution

      i)    The Company agrees to indemnify each holder of Registrable
            Securities which is included in a registration statement pursuant to
            Section 1 herein, its officers and directors and each Person who
            controls such holder (within the meaning of the Securities Act)
            against all losses, claims, damages, liabilities and expenses caused
            by any untrue or alleged untrue statement of material fact contained
            in any registration statement, prospectus or preliminary prospectus
            or any amendment thereof or supplement thereto or any omission or
            alleged omission of a material fact required to be stated therein or
            necessary to make the statements therein not misleading, except
            insofar as the same are caused by or contained in any information
            furnished in writing to the Company by such holder expressly for use
            therein or by such holder's failure to deliver a copy of the
            registration statement or prospectus or any amendments or
            supplements thereto after the Company has furnished such holder with
            a sufficient number of copies of the same. In connection with an
            underwritten offering, the Company shall indemnify such
            underwriters, their officers and directors and each Person who
            controls such underwriters (within the meaning of the Securities
            Act) to the same extent as provided above with respect to the
            indemnification of the holders of Registrable Securities.

      ii)   In connection with any registration statement in which a holder of
            Registrable Securities is participating, each such holder shall
            furnish to the Company in writing such information and affidavits as
            the Company and any underwriter reasonably requests for use in
            connection with any such registration statement or prospectus and
            shall indemnify the Company, its directors and officers and each
            Person who controls the Company (within the meaning of the
            Securities Act) against any losses, claims, damages, liabilities and
            expenses resulting from any untrue or alleged untrue statement of
            material fact contained in the registration statement, prospectus or
            preliminary prospectus or any amendment thereof or supplement
            thereto or any omission or alleged omission of a material fact
            required to be stated therein or necessary to make the statements
            therein not misleading, but only to the extent that such untrue
            statement or omission is contained in any information or affidavit
            so furnished in writing by such holder.

      iii)  Any Person entitled to indemnification hereunder shall (i) give
            prompt written notice to the indemnifying party of any claim with
            respect to which it seeks indemnification (provided that the failure
            to give prompt notice shall not impair any Person's right to
            indemnification hereunder to the extent such failure has not
            materially prejudiced the indemnifying party) and (ii) unless in
            such indemnified party's reasonable judgment a conflict of interest
            between such indemnified and indemnifying parties may exist with
            respect to such claim, permit such indemnifying party to assume the
            defense of such claim with counsel reasonably satisfactory to the
            indemnified party. If such defense is assumed, the indemnifying
            party shall not be subject to any liability for any settlement made
            by the indemnified party without its consent (but such consent shall
            not be unreasonably withheld). An indemnifying party who is not
            entitled to, or elects not to, assume the defense of a claim shall
            not be obligated to pay the fees and expenses of more than one
            counsel for all parties indemnified by such indemnifying party with
            respect to such claim, unless in the reasonable judgment of any
            indemnified party


                                       5
<PAGE>

            a conflict of interest may exist between such indemnified party and
            any other of such indemnified parties with respect to such claim.

      iv)   If the indemnification provided for in this Section 5 is unavailable
            to an indemnified party under paragraphs (a) or (b) hereof in
            respect to any losses, claims, damages, liabilities or expenses
            referred to therein, then an indemnifying party, in lieu of
            indemnifying such indemnified party, shall contribute to the amount
            paid or payable by such indemnified party as a result of such
            losses, claims, damages, liabilities or expenses in such proportion
            as is appropriate to reflect the relative fault of the Company and
            the holder of Registrable Securities in connection with the
            statements or omissions that resulted in such losses, claim,
            damages, liabilities or expenses. The relative fault of the Company
            and the holder of Registrable Securities in connection with the
            statements that resulted in such losses, claims, liabilities or
            expenses shall be determined by reference to, among other things,
            whether the untrue or alleged untrue statement of material facts or
            the omission or alleged omission to state a material fact relates to
            information supplied by the Company or the holder of the Registrable
            Securities and the parties relative intent, knowledge, access to
            information and opportunity to correct such statement or omission.

      v)    Notwithstanding any other provision of this Section, the liability
            of any holder of Registrable Securities for indemnification or
            contribution under this Section shall be individual to each holder
            and shall not exceed an amount equal to the number of shares sold by
            such holder of Registrable Securities multiplied by the net amount
            per share which he receives in such underwritten offering.

      vi)   The indemnification and contribution provided for under this
            Agreement shall remain in full force and effect regardless of any
            investigation made by or on behalf of the indemnified party or any
            officer, director or controlling Person of such indemnified party
            and shall survive the transfer of securities.

2. Representations and Warranties

2.1 The Holder (i) represents, warrants, covenants and agrees that the Warrant
and the underlying Warrant Shares are being acquired by the Holder for the
Holder's own account, for investment purposes only, and not with a view to or
for sale in connection with any distribution thereof or with any present
intention of selling or distributing all or any part of the Warrant or the
underlying Warrant Shares thereof; (ii) understands (x) that if it should

6. Stock Dividends, Reclassifications, Reorganization, Anti-Dilution Provisions,
Etc.

6.1 In case prior to the expiration of this Warrant by exercise or by its terms
the Company shall issue any shares of its Common Stock as a stock dividend or
subdivide the number of outstanding shares of Common Stock into a greater number
of shares, then, in either of such cases, the Exercise Price per share of the
Warrant Shares purchasable pursuant to this Warrant in effect at the time of
such action shall be proportionately reduced and the number of Warrant Shares
purchasable at that time shall be proportionately increased; and, conversely, in
the event the Company shall contract the number of outstanding shares of Common
Stock by combining such shares into a smaller number of shares, then, in such
case, the Exercise Price per share of the Warrant Shares purchasable pursuant to
this Warrant shall be proportionately decreased. Any dividend paid or
distributed upon the Common Stock in stock of any other class of securities
convertible into shares of Common Stock shall be treated as a dividend paid in
Common Stock to the extent that shares of Common Stock are issuable upon
conversion thereof.

6.2 In case of any consolidation or merger of the Company with or into another
corporation (other than a merger or consolidation in which the Company is the
surviving or the continuing corporation) or in the case of any sale or
conveyance to another corporation or other entity of the property, assets or
business of the Company as an entirety or substantially as an entirety, in any
such case, the Company or such successor or purchasing corporation or entity, as
the case may be, shall (i) execute with the Holder an agreement that the Holder
shall have the right thereafter to receive upon the exercise of the Warrant the
kind and amount of shares and/or other securities or other property which he
would have owned or have been entitled to receive after the happening of such
consolidation, merger, sale or conveyance had the Warrant been exercised
immediately prior to such action, (ii) make effective provision in its
certificate of its incorporation or otherwise, if necessary, in order to effect
such agreement, and (iii) set aside or reserve for the benefit of the Holder,
the stock, securities, property and cash to which the Holder would be entitled
to upon exercise of this Warrant.

6.3 In case of any reclassification or change of the Warrant Shares issuable
upon exercise of this Warrant (other than a change in par value or from no par
value to a specific par value, or as a result of a subdivision or combination,
including any change in the shares into two or more classes or series of
shares), or in the case of any consolidation or merger of another corporation
into the Company in which the Company is the continuing corporation and in which
there is a reclassification or change (including a change in the right to
receive cash or other property) of the

<PAGE>

Shares (other than a change in the par value, or from no par value to a specific
par value or, as a result of a subdivision or combination, including any change
in the shares into two or more classes or series of shares), Holder shall have
the right thereafter to receive upon exercise of this Warrant solely the kind
and amount of shares of stock and other securities, property, cash or
combination thereof receivable upon such reclassification, change, consolidation
or merger by a holder of the number of Shares for which this Warrant might have
been exercised immediately prior to such reclassification, change, consolidation
or merger.

6.4 Upon the occurrence of each event requiring an adjustment of the Exercise
Price and the number of Warrant Shares purchasable at such adjusted Exercise
Price by reason of such event in accordance with the provision of this Section
6, the Company shall compute the adjusted Exercise Price and the adjusted number
of Warrant Shares purchasable at such adjusted Exercise Price by reason of such
event in accordance with the provisions of this Section 6 and shall prepare a
certificate setting forth such adjusted Exercise Price and the adjusted number
of Warrant Shares and showing in reasonable detail the facts upon which such
determination is made. The Company shall mail to the holder of this Warrant a
copy of such Certificate, and thereafter said certificate shall be conclusive
and shall be binding upon such holder unless contested by such holder in a
written notice furnished to the Company within 15 days of the receipt thereof
setting forth in reasonable detail the basis of such contention.

6.5 In case:

(a) the Company shall take a record of the holders of its Common Stock for the
purpose of entitling them to receive a dividend or any other distribution in
respect of the Common Stock (including cash), pursuant to without limitation,
any spin-off, split-off or distribution of the Company's assets; or

(b) the Company shall take a record of the holders of its Common Stock for the
purpose of entitling them to subscribe for or purchase any shares of stock of
any class or to receive any other rights; or

(c) of any classification, reclassification or other reorganization of the
capital stock of the Company, consolidation or merger of the Company with or
into another corporation, or conveyance of all or substantially all of the
assets of the Company; or

(d) of the voluntary or involuntary dissolution, liquidation or winding up of
the Company;

then, and in any such case, the Company shall mail to the Holder, at least
twenty (20) days prior thereto, a notice stating the date or expected date on
which a record is to be taken for the purpose of such dividend or distribution
of rights, or the date on which such classification, reclassification,
reorganization, consolidation, merger, conveyance, dissolution, liquidation, or
winding up is to take place, as the case may be. Such notice shall also specify
the date or expected date, if any is to be fixed, as of which holders of Common
Stock of record shall be entitled to participate in said dividend on
distribution of rights, or shall be entitled to exchange their shares of Common
stock for securities or other property deliverable upon such classification,

<PAGE>

reclassification, reorganization, consolidation, merger, conveyance,
dissolution, liquidation, or winding up, as the case may be. The failure to give
such notice shall not affect the validity of any such proceeding or transaction
and shall not affect the right of the holder of this Warrant to participate in
said dividend, distribution of rights, or any such exchange and acquire the kind
and amount of cash, securities or other property as the Holder would have been
entitled to acquire if it was the record holder of the Warrant Shares which
could be obtained upon the exercise of the Warrants immediately before such
