            1.1 Sale and Issuance of Common Stock. Subject to the terms and
conditions of this Agreement, the Investor agrees to purchase at the Closing and
the Company agrees to sell and issue to the Investor at the Closing, one
million, eight hundred eighty thousand, nine hundred thirty-seven shares
(1,880,937) of the Company's Common Stock $0.001 par value (the "Shares"). The
purchase price for the Shares (subject to adjustment as provided in section 4.8
hereof) shall be Two Dollars and Thirteen Cents ($2.1266) per Share, or an

Price"), which purchase price assumes that such Shares will be registered under

number of shares of Common Stock outstanding immediately prior to the Closing,
on a fully diluted basis, into $31 million. The number of Shares of Common Stock
to be issued to Investor shall be determined by dividing the per share Purchase
Price, determined in the preceding sentence, into the aggregate $4 million
Purchase Price.

place at the offices of Manatt, Phelps & Phillips LLP, 3030 Hansen Way, Suite

satisfied (the "Closing"). At the Closing, the Company shall deliver to the
Investor a certificate representing the Shares against receipt by the Company
from the Investor of a wire transfer in the amount of the Purchase Price.

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

limited resale of securities purchased in a private placement subject to the

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.

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

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

                                       13

            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

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.

Effective Date, to the Company's existing or future directors, employees or

outstanding shares of common stock post-Closing (on a fully-diluted basis) by
the Company; (iv) any capital stock or other securities (or related options or
warrants) offered or issued to directors, officers or employees of, or

Common Stock of the Company held by the Investor on the day immediately
preceding the date of the notice described in subsection (c) below to the total

Right, shall mean all New Securities which the Company intends to offer for sale

                  (iii) If at any time from the Closing through December 31,

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
purchase its Pro Rata Share, the Company shall thereafter be free to offer, sell
and issue the New Securities, including any such Pro Rata Share not purchased by
the Investor, to any third party so long as such sale is at a price and is upon
general terms no more favorable than described in the Company's notice.

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

            4.7 Board Observer. The Company hereby covenants and agrees with
Investor that, as long as the Alliance Agreement (defined below) remains in
effect, the Investor shall have the right to designate a person (an "Observer")
to be present at all meetings of the Board of Directors of the Company and all
committees thereof. The Company will give such Observer reasonable prior notice
(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
Shares (the "Registration Statement") and shall use its best efforts to cause
such registration statement to be declared effective within 90 days following
the Closing. The Company further covenants and agrees to maintain the
Registration Statement Effective for one year following the effective date of
the Registration Statement, provided, that, notwithstanding the foregoing, if at
any time or from time to time after the date of effectiveness of the
Registration Statement, the Company notifies the Investors in writing of the
existence of a Potential Material Event, the Investors shall not offer or sell
any Shares, or engage in any other transaction involving or relating to the
Shares, from the time of the giving of notice with respect to a Potential
Material Event until such Investor receives written notice from the Company that
such Potential Material Event either has been disclosed to the public or no
longer constitutes a Potential Material Event; provided, however, that the
Company may not so suspend such right to the


                                       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
have been declared effective, such number of shares of Common Stock as shall be
equal to one and one quarter percent (1 1/4%) of the number of Shares issued

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.

Gentlemen:

      As General Counsel of TTR Technologies, Inc., a Delaware corporation (the

Section 5.6 of the Agreement. Capitalized terms used herein are as defined in
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
appropriate for the purpose of this opinion.

amended, modified or terminated since the date they were submitted to me by
written or oral agreement of the parties thereto, by the conduct of the parties
thereto or otherwise; facsimile signatures have the same legal effect as

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

      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
will conform, with all notice requirements in statutes, law rules, regulations

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

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

      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
