                                   WITNESSETH:

      WHEREAS, CDbeat and Cadnetics entered into that certain Letter of Intent
dated January 13, 1999 (the "Letter");

      WHEREAS, pursuant to the Letter, Cadnetics performed certain work for

      WHEREAS, CDbeat is attempting to close a business combination with
Cakewalk LLC, which closing (the "Closing") is scheduled for November 12, 1999;

      WHEREAS, for purposes of the Closing, CDbeat requires that it and
Cadnetics complete certain mutual obligations under the Letter.

      NOW, THEREFORE, in consideration of the premises and for other good and
valuable consideration, the receipt and sufficiency of which is acknowledged,
the parties hereto hereby agree as follows.

      1.    Cadnetics represents and warrants that, prior to payment in full
            under the Letter, it owns full right, title and interest in and to
            the CDbeat application, which has been generally described in the
            Letter as an interactive web enabled audio-CD music player (the
            "Application").

      2.    Cadnetics represents and warrants that it has never transferred or
            licensed any right, title or interest in and to the Application to
            any other party.

      3.    Subject to paragraph 6 hereof, Cadnetics hereby transfers to CDbeat,
            and warrants good title to, the Application and all Intellectual
            Property rights, including copyrights and all inventions, whether
            patentable in the United States or elsewhere, conceived during the
            Work and related to the Application.

      4.    Cadnetics shall immediately provide CDbeat with an assignment of the
            Intellectual Property rights in and to the Application, together
            with a confidentiality agreement, executed by each of the employees
            and contractors listed on Schedule A attached hereto. A form of
            Assignment of Rights and Confidentiality Agreement is attached as
            Schedule B hereto (the "Assignment"). Cadnetics represents and
            warrants to CDbeat that the

            persons listed on Schedule A constitute all of the employees and
            contractors who participated in the Work or were involved in the
            Application.

      5.    Upon Closing, and upon receipt by CDbeat of an Assignment from each
            of the individuals set forth in Schedule A hereto, CDbeat shall pay
            Cadnetics US$48,243.36 in full and complete satisfaction of all
            financial obligations under the Letter, including paragraph 7.4
            thereof, otherwise this Agreement is null and void.

      6.    Upon payment of the amount set forth in paragraph 5 hereof, CDbeat
            shall be deemed to have acquired full right, title and interest in
            and to the Application as well as the source code to the
            Application, and Cadnetics acknowledges and confirms that CDbeat
            shall own all proprietary interest in and to the Application and the
            source code.

      7.    Cadnetics confirms and acknowledges that CDbeat shall be entitled to
            use all rights in respect of all ideas incorporated for the specific
            development of the Application that are not generally known by
            skilled programmers.

      8.    Cadnetics agrees to keep confidential all knowledge of the CDbeat
            project, development and software, including the Application.

      9.    Cadnetics agrees that it will not, directly or indirectly, in
            violation of the confidentiality and other protective provisions of
            the Letter and this Agreement, work for, create or be involved with
            any other application involving the interactive web enabled audio CD
            music player. Notwithstanding anything contained herein to the
            contrary, the foregoing shall not, however, prevent Cadnetics from
            working for clients, or for their own account, on projects using all
            rights to all ideas incorporated in the Application for development
            of other applications, from using architecture similar to the
            Application, or from working on applications that have similar uses
            as the Application, provided that they do not violate the above.

      10.   Subject to the terms of paragraph 9 hereof CDbeat acknowledges that
            Cadnetics is an independent software developer and that it shall not
            impose any restrictions on Cadnetics in respect of the development
            of applications.

      11.   In the event that CDbeat shall desire to assign the rights under the
            Letter to any third party, the provisions of paragraph 13.5 thereof
            shall be applicable but Cadnetic's consent shall not be unreasonably
            withheld.

      12.   This Agreement shall supercede and replace the Letter in the event
            of any duplication, overlap or conflict between the two documents.

and have executed the same as of the date and year first set forth above.
