     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 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

     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)) 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) Evaluated the effectiveness of the registrant's disclosure controls and
procedures and presented in this annual 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

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.
