    (b)  Licensee shall render to Licensor true and detailed accounting
         statements, in electronic or digital format, of all royalties payable
         hereunder no less often than fifteen (15) days following its receipt of
         the monthly payment from Approved Sublicensees, but in no event shall
         such payments be made later than thirty (30) days after the end of each
         calendar month. The statements shall report all royalty bearing
         transactions on a Recording-by-Recording basis, including but not
         limited to reporting on each Recording by title, performing artist,
         total revenue received from Subscibers, the number of subscriptions of
         such Recording, the amount of tax to be withheld and the resultant
         Royalty payable hereunder. Each accounting statement shall be
         accompanied by payment to Licensor of all royalties due.

    (c)  All payments to Licensor shall be computed in Reminbi and remitted to
         Licensor in United States dollars to an account in Hong Kong designated
         by Licensor. Each conversion from another currency for the purpose of
         computing such payments shall be calculated at the rate of exchange in
         effect on the date the statement concerned is rendered.

    (d)  Licensee shall maintain accurate and complete records and accounting
         books with regard to the licensing and exploitation of the Recordings,

         particular statement only once. Upon no less than thirty (30) days'
         notice, Licensor may conduct such audit during Licensee's normal
         business hours at the place where Licensee keeps such records and books

         expense, except that if any audit reveals an error resulting in
         underpayment to Licensor of five (5%) percent or more of the total
         amount accounted to Licensor during the accounting periods audited,
         Licensee shall pay to Licensor all reasonable audit costs, including
         travel, hotel and per diems, together with the underpayment. Any
         royalties owed and unpaid to Licensor shall accumulate interest at one

Attn: Mr. Raymond Yang. CEO

Dear Sirs,

RING BACK TONE LICENSE AGREEMENT DATED AS OF 6TH MAY, 2003

We refer to the ring back tone license agreement dated as of 6th May, 2003
between ourselves as licensor and yourselves as licensee, as it may be amended
in writing from time to time (the "License Agreement"). Terms defined in the
License Agreement shall have the same meaning when used herein.

We are writing to confirm that we agree to renew the Term of the Agreement for 6
months (ie., until 11th May, 2004, hereafter the "Renewed Term"), subject to the
following conditions:

1.       You will pay us quarterly advances (each an "Advance") effective from
         1st January, 2004. The amount of each Advance shall be equal to the
         Royalty payable by you to us in the preceding calendar quarter and the
         Advance shall be paid when you account Royalty to us for March, June,
         September or December (as the case may be) pursuant to clause 3 of the
         License Agreement and the first Advance shall be due in January 2004.
         Each Advance paid is not refundable, but is recoupable from all the
         Royalty payable by you to us under clause 3 of the License Agreement
         during the relevant calendar quarter. For instance, when you account
         Royalty to us for December 2003 in January 2004 pursuant to clause 3 of
         the License Agreement, you have to pay us at the same time an Advance
         equal to all the Royalty paid or payable by you to us for the period
         from 1st October to 31st December, 2003 and that such Advance is only
         recoupable from the Royalty payable by you to us during the period 1st
         January to 31st March, 2004. The

                                       17
<PAGE>

         amount of Advance will be pro-rated for the remainder of the Term which
         is shorter than a calendar quarter.

2.       We have the right to terminate the exclusivity of this Agreement by
         giving you 7 days of prior written notice if the ring back tone service
         is also available directly through any content providers (rather than
         through mobile operators atone).

3.       The automatic renewal option provided for under the heading "Term" in
         schedule A of the License Agreement is not applicable in the Renewed
         Term.

4.       You will continue to comply with your obligations under the License
         Agreement and that you will also procure the Sub-licensees to comply
         with the terms of the License Agreement to the extent that such terms
         are applicable to them during the Renewed Term.

Save as amended hereunder, the License Agreement shall remain in full force and
effect. Please confirm your agreement to the above by signing and returning the
duplicate copy of this letter to us.

Yours faithfully,
For and on behalf of
Sony Music (Asia) Inc.
