155,856,000 Shares represents 27.8% of the total outstanding Issuer Equity Shares, based on a total
of 561,000,000 Issuer Equity Shares outstanding as of December&nbsp;31, 2010, as reported in the
Issuer&#146;s Form 20-F for the fiscal year ended December&nbsp;31, 2010. The bylaws of the Issuer provide
that no holder of Shares may hold in excess of 10.0% of the total outstanding Issuer Equity Shares,
or exercise voting rights with respect to such excess Shares. As a result of such provision, Grupo
M&#233;xico may be required to dispose in the open market of 99,756,000 of its Shares in order to reduce
its beneficial ownership of Issuer Equity Shares

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">to 10.0% of the outstanding Issuer Equity Shares, and it does not have the ability to exercise
voting rights with respect to such number of Shares. As previously reported, representatives of the
Issuer asked Grupo M&#233;xico and ITM to dispose of Shares in order to reduce Grupo M&#233;xico&#146;s beneficial
ownership of Issuer Equity Shares to 10.0% of the total outstanding Issuer Equity Shares. Grupo
M&#233;xico and ITM have filed a claim with the relevant Court in Mexico seeking, among other things,
that the Court determine that such provisions of the Issuer&#146;s bylaws are invalid under applicable
Mexican law. As previously reported, Grupo M&#233;xico has announced that its Board of Directors
approved the acquisition (directly or indirectly) of more than 30.0% and up to 100.0% of the Issuer
Equity Shares currently outstanding, excluding treasury shares. In connection with any such
transaction, Grupo M&#233;xico will be required to launch a mandatory public tender offer, or OPA, for
100% of the Issuer Equity Shares currently outstanding, in accordance with Mexican securities laws
and any other applicable laws. As previously reported, the Reporting Persons had applied for
Mexican National Banking and Securities Commission (<I>Comisi&#243;n Nacional Bancaria y de Valores</I>)
(&#147;CNBV&#148;) authorization of an OPA. The Issuer and related parties have filed certain claims in
Mexico and obtained a suspension of the issuance of such authorization by the CNBV, pending final
decision on the merits of the claims. The Reporting Persons intend to appeal the decision ordering
the suspension of the authorization by the CNBV.
