have reviewed this quarterly report on Form 10-QSB;

2.   Based
on my knowledge, this quarterly 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 quarterly report;

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)

| | (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 quarterly report is being prepared;
| | --- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (b) |  | evaluated
the effectiveness of the registrants disclosure controls and
                    procedures and presented in this 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

| | (c) |  | 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 registration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 registrants board of directors (or persons performing the
equivalent function):

| | (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.
