* Pursuant to the concurrent cash tender offers in Mexico (the “Mexican Offer”) and the United States (the “U.S. Offer” and, together with the Mexican Offer, the “Tender Offers”) to acquire all of the issued and outstanding (i) Series B shares (the “Series B Shares”) of Banco Santander México, S.A., Institución de Banca Múltiple, Grupo Financiero Santander México (“Santander Mexico”) and (ii) American Depositary Shares (each of which represents five Series B Shares) of Santander Mexico (the “ADSs”), in each case other than any Series B Shares or ADSs owned, directly or indirectly, by Banco Santander, S.A. (“Banco Santander”), Banco Santander acquired a total of 244,306,313 Series B Shares, including Series B Shares represented by ADSs. Following the expiration of the Tender Offers, Santander Mexico has fewer than 300 record holders. Pursuant to Mexican law, Banco Santander and Santander Mexico will incorporate a repurchase trust (fideicomiso) (a “Repurchase Trust”) on the date of the deregistration of the Series B Shares with the Mexican National Securities Registry of the Comisión Nacional Bancaria y de Valores. Holders of Series B Shares that remain outstanding following completion of the Tender Offers will have the right, but not the obligation, to sell their Series B Shares to the Repurchase Trust at any time during a period of six (6) months from the date the Repurchase Trust is incorporated for the same cash consideration that they would have received during the Mexican Offer in respect of their Series B Shares (the “Statutory Sell-out”). The Statutory Sell-out will be treated as a six-month subsequent offering period to the U.S. Offer. Under Mexican law and regulations, the Statutory Sell-out will not be treated as a tender offer in Mexico or a subsequent offering period of the Mexican Offer. The number of record holders is expected to decrease as a result of sales of Series B Shares to the Repurchase Trust.

Pursuant to the requirements of the Securities Exchange Act of 1934, Banco Santander México, S.A., Institución De Banca Múltiple, Grupo Financiero Santander México has caused this certification/notice to be signed on its behalf by the undersigned duly authorized person.
