As a foreign private issuer with shares listed on the NYSE, we are subject to different corporate governance requirements than a U.S. company under the NYSE listing standards. With certain exceptions, foreign private issuers are permitted to follow home country practice standards. Pursuant to Rule 303.A11 of the NYSE listed company manual, we are required to provide a summary of the significant ways in which our corporate governance practices differ from those required for U.S. companies under the NYSE listing standards.

We are a Mexican corporation with shares, in the form of CPOs listed on the Bolsa Mexicana de Valores, or Mexican Stock Exchange. Our corporate governance practices are governed by our bylaws, the Mexican Securities Market Law, and the regulations issued by the CNBV and the Mexican Stock Exchange. Although compliance is not mandatory, we also substantially comply with the Mexican Code of Best Corporate Practices (Código de Mejores Prácticas Corporativas), which was created in January 1999 by a group of Mexican business leaders and was endorsed by the Mexican Banking and Securities Commission. See "- Bylaws" for a more detailed description of our corporate governance practices.

The table below sets forth a description of the significant differences between corporate governance practices required for U.S. companies under the NYSE listing standards and the Mexican corporate governance standards that govern our practices.

NYSE rules		Mexican rules
Listed companies must have a majority of independent directors		The Mexican Securities Market Law requires that listed companies have at least 25% of independent directors. Our stockholder's meeting is required to make a determination as to the independence of the directors. The definition of independence under the Mexican Securities Market Law differs in some aspects from the one applicable to U.S. issuers under the NYSE standard and prohibits, among other relationships, an independent director from being an employee or officer of the company or a stockholder that may have influence over our officers, relevant clients and contractors, as well as certain relationships between the independent director and family members of the independent director. In addition, our bylaws broaden the definition of independent director. Our bylaws provide for an executive committee of our board of directors. The executive committee is currently composed of six members, and there are no applicable Mexican rules that require any of the members to be independent. The executive committee may generally exercise the powers of our board of directors, subject to certain exceptions. Our Chief Executive Officer is a member of our board of directors and the executive committee.
Listed companies must have a nominating/corporate governance committee composed entirely of independent directors.		Listed companies are required to have a corporate practices committee.
Listed companies must have a compensation committee composed entirely of independent directors.		The Mexican Code of Best Corporate Practices recommends listed companies to have a compensation committee. While these rules are not legally binding, companies failing to comply with the Mexican Code of Best Business Practices' recommendation must disclose publicly why their practices differ from those recommended by the Mexican Code of Best Business Practices.
Listed companies must have an audit committee with a minimum of three members and must be independent.		The Mexican Securities Market Law requires that listed companies must have an audit committee. The Chairman and the majority of the members must be independent.
Non-management directors must meet at regularly scheduled executive sessions without management.		Our non-management directors are not required to meet at executive sessions. The Mexican Code of Best Corporate Practices does not expressly recommend executive sessions.
Listed companies must require shareholder approval for equity compensation plans, subject to limited exemptions.		Companies listed on the Mexican Stock Exchange are required to obtain shareholder approval for equity compensation plans, provided that such plans are subject to certain conditions.
Listed companies must adopt and disclose a code of business conduct and ethics for directors, officers and employees, and promptly disclose any waivers of the code for directors or executive officers.		Companies listed on the Mexican Stock Exchange are not required to adopt a code of ethics. However, we have adopted a code of ethics which is available free of charge through our offices. See - "Code of Ethics" for directions on how to obtain a copy of our code of ethics. Waivers involving any of our executive officers or directors will be made only by our Board of Directors or a designated committee of the Board.
