(PCA);
(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 PCA as of, and for, the periods presented in this report;
(4) PCAs other certifying officer 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 PCA 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
PCA, 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 PCAs disclosure controls and procedures and presented in
this report our conclusions about the effectiveness of the disclosure controls and procedures, as

that occurred during PCAs most recent fiscal quarter (PCAs fourth fiscal quarter in the case of
an annual report) that has materially affected, or is reasonably likely to materially affect,
PCAs internal control over financial reporting; and
(5) PCAs other certifying officer and I have disclosed, based on our most recent evaluation
of internal control over financial reporting, to PCAs auditors and the Audit Committee of PCAs
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 PCAs
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 PCAs internal control over financial reporting.
