> 
1. I have reviewed this annual report      on Form 20-F of Vitro, S.A.B. de C.V.;

2. Based on my knowledge, this report      does not contain any untrue statement of a material fact or omit to state      a material fact necessary to make the statements made, in light of the circumstances      under which such statements were made, not misleading with respect to the      period covered by this report;

3. Based on my knowledge, the financial      statements, and other financial information included in this report, fairly      present in all material respects the financial condition, results of operations      and cash flows of the registrant as of, and for, the periods presented in      this report;

4. The registrant's other certifying      officers and I are responsible for establishing and maintaining disclosure      controls and procedures (as defined in Exchange Act Rules 13a-15(e) and      15d-15(e)) and internal control over financial reporting (as defined in      Exchange Act Rule 13a-15(f) and 15d-15(f))for the registrant and have:

(a) designed such disclosure controls        and procedures, or caused such disclosure controls and procedures to be        designed under our supervision, to ensure that material information relating        to the registrant, including its consolidated subsidiaries, is made known        to us by others within those entities, particularly during the period        in which this report is being prepared;

(b) designed such internal control over        financial reporting, or caused such internal control over financial reporting        to be designed under our supervision, to provide reasonable assurance        regarding the reliability of financial reporting and the preparation of        financial statements for external purposes in accordance with generally        accepted accounting principles; 

(c) evaluated the effectiveness of the        registrant's disclosure controls and procedures and presented in this        report our conclusions about the effectiveness of the disclosure controls        and procedures, as of the end of the period covered by this report based        on such evaluation; and

(d) disclosed in this report any change        in the registrant's internal control over financial reporting that occurred        during the period covered by the annual report that has materially affected,        or is reasonably likely to materially affect, the registrant's internal        control over financial reporting; and

5. The registrant's other certifying      officers and I have disclosed, based on our most recent evaluation of internal      control over financial reporting, to the registrant's auditors and the audit      committee of the registrant's board of directors:

(a) all significant deficiencies and        material weaknesses in the design or operation of internal control over        financial reporting which are reasonably likely to adversely affect the        registrant's ability to record, process, summarize and report financial        information; and 

(b) any fraud, whether or not material,        that involves management or other employees who have a significant role        in the registrant's internal control over financial reporting.
