thereof from MP3.com to Buyer, MP3.com shall be entitled to draw-down against
the letter of credit described in SECTION 2.6 in an amount equal to such
scheduled payment.

               2.6 LATE PAYMENTS; TAXES. Any late payments under this Agreement
will be assessed a service fee of one and one-half percent (1.5%) per month, to
the extent allowed by law. All fees owed by Buyer to MP3.com are exclusive of,

upon either Party in connection with this Agreement, except for taxes based on

delivered to MP3.com an irrevocable letter of credit (the "LETTER OF CREDIT") in
the face amount of one hundred and five million US dollars ($105,000,000) naming
