such disclosure controls and procedures, or caused                   such disclosure
controls and procedures to be designed under                   our supervision, to ensure

consolidated subsidiaries, is                   made known to us by others within those

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;

| | --- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (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 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.
| | --- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

5. The registrants other certifying
officer 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

control over financial reporting.
