1. On October 30, 2000, the parties  signed a simple Credit  Agreement for up to
an  amount  of USD  35,000,000.00  (Thirty-five  million  dollars  in the  legal
currency of the United States of America). Also appearing in this agreement were
the companies  Desarrollos  Empresariales,  S.A. de C.V., and Radiodifusion Red,
S.A. de C.V., which provided guarantee for the loan based on the stocks of their
subsidiaries  which  they  own,  and which are  listed  in  Exhibit  "A" of this
instrument,  as security for  compliance  of the  obligations  undertaken by the
Borrower towards the Lender. The Credit agreement was certified by Esther Garcia
Alvarez, Notary Public, holding commission number 4 of the Federal District; for
the purposes of this amendment agreement,  it shall be identified as the "Credit
Agreement", including the amendments which have been made thereto up to the date
this document was signed.

2. On February 20, 2001, the parties signed an amendment agreement to modify the
Credit  Agreement cited in the paragraph  above, in which the Lender allowed the
Borrower  to take on  liabilities  with  third  parties  up to the amount of USD
3,500,000.00  (Three million five hundred thousand dollars in the legal currency
of the United States of America) in addition to the amount originally authorized
in the Credit Agreement.

3. On April 17, 2001 the parties  signed an  amendment  agreement  to modify the
Credit  Agreement  cited in paragraph  one here, in which it was agreed that the
interest rate applicable would be equivalent to the LIBOR rate plus 3.00 (three)
percentage  points.  In addition,  the parties agreed to reset the timetable for
the loan payments,  each payment being for the amount of USD 3,900,000.00 (Three
million nine hundred thousand dollars in the legal currency of the United States
of America) with the last of the payments to be made on October 31, 2005 for the

liabilities with third parties up to the amount of USD 2,500,000.00 (Two million
five  hundred  thousand  dollars in the legal  currency of the United  States of

5. On November  15, 2001 the  Borrower  notified  the Lender that it had begun a
corporate  restructuring  process  for the purpose of  improving  control of the

6. On December 10, 2000 the parties signed an Amendment  Agreement to the Credit

Borrower  acknowledged  the debt and  agreed to pay the Lender the amount of USD
23,300,000.00  (Twenty-three million three hundred thousand dollars in the legal
currency of the United States of America) and the parties agreed to convert 100%
of the acknowledged amount into pesos,  National Currency,  and consequently the
Borrower agreed to pay the Lender the amount of  MXP238,242,500.00  (Two hundred
thirty eight  million two hundred  forty two thousand  five hundred pesos 00/100
National Currency).

7. In the Amendment Agreement cited in the paragraph directly above, the parties
also agreed to change the payment dates,  the sums of  corresponding  repayments
and how to  determine  the  manner in which  interest  would be  applied  to the
acknowledged  Debt  Amount  converted  to  National   Currency.   The  financial
indicators were changed and a number of affirmative and negative  covenants were
added, along with justifications for early termination.  As a consequence of the
corporate restructuring process of the Borrower, Desarrollos Empresariales, S.A.
de C.V.,  and  Enlaces  Troncales,  S.A.  de C.V.  appeared  for this  Amendment
Agreement,  posting  security  for  the  Lender  based  on  the  stocks  of  its
proprietary subsidiaries.

Currency).  In  addition,  the  Borrower  and the Loan  Guarantors  ratified and
extended the Security Guarantee posted for the Lender.

9. In the Amendment Agreement described in paragraph directly above, the parties
agreed  likewise to change the payment dates,  the amounts of the  corresponding
repayments  and to  modify  some  of the  affirmative  and  negative  covenants.
Likewise,  Desarrollos Empresariales,  S.A. de C.V., and Enlaces Troncales, S.A.
de C.V.  acknowledged  the debt and  acknowledged  they were co-debtors with the
Borrower to the Lender.

10. On December 3, 2003, the parties signed an Amendment Agreement to the Credit
Agreement,  which was certified by Esther Garcia Alvarez, Notary Public, holding
commission  number 4 of the Federal  District,  by act number  44151 of the same
date. In said amendment agreement the Borrower  acknowledged the debt and agreed
to pay the Lender the amount of MXP176,  473, 33.00 (one hundred and seventy-six
million  four  hundred  seventy-three  thousand  thirty-three  pesos and  00/100
National Currency).  In addition,  the Borrower and the Loan Guarantors ratified
and  extended  the  Security  Guarantee  posted for the Lender,  and in the same
manner, the Co-Debtors ratified their obligations in favor of the Lender.

11. In the Amendment Agreement  described in the preceding,  the parties agreed,
among  other  points,   to  modify  the  payment  dates,   the  imports  of  the
corresponding  payments,  the  calculations  of interests and to modify  certain
affirmative and negative covenants.
