To Whom It May Concern:
We hereby inform you of the following relevant fact, pursuant to Article 9 and second paragraph of Article 10 of Law No 18.045 in the Norma de Carácter General No. 30 and Circular No. 1375, both of this Superintendence.
LAN Airlines S.A. (“LAN”) has decided to implement a change in its American Depositary Receipt (“ADR”) program by modifying the number of shares of LAN represented by each American Depositary Share (“ADS”). Currently, each ADS represents five shares of LAN. By virtue of the proposed change, each ADS would represent one share of LAN.
For this purpose, LAN has communicated its instructions to The Bank of New York, in its capacity as depositary under the ADR program. According to the timetable prepared by such bank, and notwithstanding any special circumstances that may require the modification of the timetable, the proposed change would be effective on August 16, 2007.
With no further matters, yours sincerely,
Alejandro de la Fuente G.
Chief Financial Officer
