ESSENTIAL FACT

SUPERMERCADOS UNIMARC S.A.

Inscription Registers of Values number 447

According to article ninth and ten of the Law 18.045 and General Regulation number 30 issued by the Chilean Securities and Insurance Superintendency, I hereby communicate a relevant information on the Company:

Dated May 14, 2007, Supermercados Unimarc S.A. has been notified of the ruling made by the Chilean Supreme Court in the case filed as "State Street Bank and Trust Company against Inversiones Errazuriz and others", File number 2349-2005, by means of which, this Court grants the exequatur claimed by such Bank, in respect to the sentence dictated on December 4, 2001 and amended on May 7, 2002 by the South District Court of the United States, against Inversiones Errazuriz S.A. and Supermercados Unimarc S.A. as only part of some related companies, for the amount of US$ 136.436.875 (one hundred thirty six million, four hundred and thirty six thousand and eight hundred and seventy five dollars of the United States), plus the interest charges established in such sentence. In conformity with the ruling made by the Supreme Court of the Republic, the discussions about the merits and grounds of such fulfillment, shall be resolved by the Chilean courts.

It is the opinion of our lawyers that this ruling sets aside the demurrer for a three year prescription claimed by the defendant, which will be filed in the event the fulfillment of such ruling is enforced, leaving also pending to resolve the discussion about the validity of jurisdiction clauses, the prescription and extinction of the debts, and their novation, matters which are being discussed before the 27 Civil Court of Santiago.

If the defendants' arguments are rejected by the Chilean courts, Unimarc may be liable for the full amount due pursuant to the judgment, including applicable interest.
