Incorporated and Goldman, Sachs & Co. (the "Representatives"). An additional 2,362,500 shares may be sold by the Company in connection with the over-allotment option, as contemplated by the Company's Registration Statements on Form F-1 (Nos.333-129967 and 333- ), filed with the SEC on November 28, 2005 and December 14, 2005 (as amended, the "Registration Statement.")

We have examined originals or copies, certified or otherwise identified to our satisfaction, of the Registration Statement, the Prospectus, the Articles of Incorporation, the power of attorney and other such documents, corporate records and other instruments as we have deemed necessary or advisable for the purpose of rendering this opinion. We have assumed the genuineness of all signatures and the authenticity of all documents submitted to us as originals and the conformity to original documents of all documents submitted to us as copies or facsimiles.

Based upon the foregoing, we are of the opinion that the Company's Class A shares are duly and validly authorized, legally issued, fully paid and non-assessable. We are qualified to practice law in the Republic of Panama and accordingly, express no legal opinion herein based upon any other laws other than the laws of Panama. We hereby consent to the filing of this opinion as Exhibit 5.1 to the Registration Statement and to the reference to us under the captions "Validity of Securities" and "Enforcement of Civil Liabilities" in the Prospectus constituting a part of the Registration Statement. Yours Very Truly, GALINDO, ARIAS & LOPEZ Ramon Ricardo Arias
