clarifications.

1.- Motormexa S.A. de C.V. and its shareholders paid all of their debts
to the creditor banks on December 16, 2002, before a Notary Public and the
representatives of the financial institutions.

Million Dollars), simulation of legal actions and simulation of evidence,
false declaration before authorities, procedural fraud and attempted fraud.

3.- The experts appointed by the Mexico City District Attorney's Office
("Procuraduria General de Justicia del Distrito Federal") issued a report on
March 2, 2007, whereby they determined in an unequivocal manner, that the
signatures in the documents allegedly executed by Motormexa, and its
shareholders are forged and cannot be attributed to the people in question.

4.- Based on a detailed series of conclusions derived from the District
Attorney preliminary investigation number FPC-74-T2-692-06-10, Attorney at
law Blanca Rosa Ham Garcia, District Attorney Agent #74 of Mexico City,
Federal District, determined in her conclusions to exercise criminal legal
action against Mr. Rufino Vigil Gonzalez, as defendant and probable

entity, and its owners; requesting Judge #32 in criminal matters of Mexico
City, Federal District, Attorney at law Jesus Ubando Lopez, to issue the
corresponding arrest warrant.
