2. Based
on my knowledge, this annual report does not contain any untrue statement of a
material fact or omit to state a material fact necessary to make the statements

included in this annual report, fairly present in all material respects the
financial condition, results of operations and cash flows of the registrant as

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 controls 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 annual 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;

evaluated the effectiveness of the registrant’s disclosure controls and

Disclosed in this annual report any change in the registrant’s internal control
over financial reporting that occurred during 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 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 (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.
