GRUPO TMM, S.A. ANNOUNCES EXTENSION OF EXCHANGE OFFERS
AND CONSENT SOLICITATIONS FOR ITS 9 1/2 % SENIOR NOTES DUE 2003
AND 10 1/4 % SENIOR NOTES DUE 2006

Mexico City, May 13, 2003 - Grupo TMM, S.A. (NYSE: TMM and BMV: TMM A) ("Grupo TMM" or the "Company"), announced today that it has extended the expiration date of its previously announced exchange offers and consent solicitations for all of its outstanding 9 1/2 percent Senior Notes due 2003 ("2003 notes") and its 10 1/4 percent Senior Notes due 2006 ("2006 notes") until midnight, New York City time, on May 13, 2003. As of midnight, New York City time, on May 12, 2003, approximately 48.01 percent of the outstanding 2003 notes, or $84,918,000 principal amount, had been tendered and not withdrawn, and 84.59 percent of the outstanding 2006 notes, or $169,191,000 principal amount, representing a majority of the 2006 notes, had been tendered and not withdrawn.

As previously disclosed, the Company's 2003 notes mature on May 15, 2003. The Company does not have sufficient liquidity to pay the 2003 notes at maturity. The Company's ability to pay any untendered 2003 notes that remain outstanding at the completion of the exchange offers will depend on a number of factors, including the amount of 2003 notes that remain outstanding and the ability of the Company to extend or renew its receivables securitization facility or obtain additional funds. It is unlikely that the Company will have sufficient funds to pay the remaining untendered 2003 notes at maturity if only the minimum level of tenders is received.

Citigroup Global Markets Inc. is acting as the dealer manager for the exchange offers and consent solicitations.
