Report of Independent Registered Public Accounting Firm
 
 The Board of Directors and Stockholders:
 Farmacias Ahumada S.A.:
  
 We have audited the accompanying consolidated balance sheet of Farmacias Ahumada S.A. and subsidiaries as of December 31, 2010 and the related consolidated statements of income, changes in stockholders’ equity and cash flows for the period from October 3, 2010 (the date of disposal) to December 31, 2010. These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audit.
  We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States).Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.
  The management of Farmacias Ahumada, S.A. decided to omit the 2009 comparative financial statement and their related notes as required by Mexican Financial Reporting Standards.
  In our opinion, except for the omission of the comparative financial information as discussed in the preceding paragraph, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Farmacias Ahumada S.A. and subsidiaries as of December 31, 2010, and the results of their operations and their cash flows for the period from October 3, 2010 (the date of disposal) to December 31, 2010, in conformity with Mexican Financial Reporting Standards.
  Mexican Financial Reporting Standards vary in certain significant respects from U.S. generally accepted accounting principles. The management of Farmacias Ahumada, S.A. decided to omit information relating to the nature and effect of such differences in these consolidated financial statements.
