CERTIFICATION
I, Catherine A. Lesjak, certify that:

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 officer(s) 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 Rules 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

the registrant’ s most recent fiscal quarter (the registrant’ s fourth fiscal quarter in the case of an 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 officer(s) 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 (or
persons performing the equivalent functions):
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.
