     of the Borrower in favor of the Lender. The loan agreement was ratified
     before Licenciada Maria Esther Garcia Alvarez, Notary Public number 4 in
     the Distrito Federal.

     For the purposes of this agreement, the loan agreement referred to in this
     agreement, as well as its modifying agreements referred to in the following

     thousand Dollars, legal currency of the United States of America), in
     addition to the amount originally authorized in the Loan Agreement.

3.   On April 17, 2001, the parties signed an agreement letter in order to
     modify the Loan Agreement, where they agreed that the applicable interest
     rate would be equivalent to the LIBOR Rate plus 3.00 (three) percentage
     points. In the same document, the parties agreed to the rescheduling of the
     credit payments, each one for an amount of U.S.$3,900,000.00 (Tthree
