         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, changes in net

         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)  Omitted.]

         evaluation; and

d)       disclosed in this report any change in the registrant's internal
         control over financial reporting that occurred during the registrant's
         most recent fiscal half-year (the registrant's second fiscal half-year
         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 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
         controls over financial reporting.
