ESSENTIAL FACT

Supermercados Unimarc S.A.

Pursuant to article 9 and to the second paragraph of article 10, of law number 18,045; and pursuant to General Regulation number 30, herein I inform you, certain essential fact.

On August 4^th, 2005, it was held the Board of Director's meeting of the Company, Supermercados Unimarc S.A. At such meeting, the Board of Director acknowledged that the Company has been notified, together with other related corporations, of an exequatur requested before the Supreme Court of Chile. The exequatur is being requested by the State Street Bank and Trust Company. Regarding the above mentioned, the company has decided to answer the request of exequatur, pleading such request be rejected, as per the arguments and reasons therein explained.

The Exequatur request does not comply with any of the requisites by Chilean Legislation in order to be recognized as such. Furthermore, the judicial decision's content is against Chilean Public Order and National Jurisdiction, besides there was not a due process, among other allegations. For the reason stated, the judicial decision lacks legal validity.

HECHO ESENCIAL

SUPERMERCADOS UNIMARC S.A.

De conformidad al articulo 9 e inciso segundo del articulo 10 de la Ley 18,045, y de conformidad a lo senalado en la N.C.G. numero 30, informo cierto hecho que reviste el caracter de esencial o relevante para la sociedad.

Que habiendose reunido, con fecha 4 de Agosto de 2005, el Directorio de Supermercados Unimarc S.A., tomo conocimiento de haber sido notificado de la solicitud de exequatur promovida ante la Excma. Corte Suprema, por el banco extranjero, State Street Bank and Trust Company; y ha decidido evacuar el traslado conferido. En aquel se solicita al Maximo Tribunal que la peticion sea rechazada en todas sus partes, por los argumentos contenidos en la presentacion correspondiente.

En la especie, el exequatur no cumple con ninguno de los requisitos exigidos por las disposiciones legales para ser reconocido en Chile, siendo contrario a las leyes de la Republica. Ademas, viola el orden publico y contradice la jurisdiccion nacional, al haber carecido la causa de todos los requisitos de un debido proceso, ello, entre muchas otras razones de hecho y de derecho que le restan toda validez legal.
