I express no opinion with respect to the transactions referred to herein or in the Registration Statement other than as expressly set forth herein, nor do I express any opinion herein concerning any law other than the tax laws of the Republic of Chile in force and as interpreted at the date of this opinion. I have not, for purposes of this opinion, made any investigation of the laws, rules or regulations of any other jurisdiction.

I hereby consent to the filing with the U.S. Securities and Exchange Commission of this opinion as an exhibit to the Registration Statement, and to the references made to me under the captions “Material Chilean Tax Consequences” and “Legal Matters” in the Registration Statement. In giving such consent, I do not thereby admit that I am an expert with respect to any part of the Registration Statement, including this exhibit, within the meaning of the term “expert” as used in the Securities Act of 1933, as amended.
