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;





3.

4.     I am responsible for establishing and maintaining disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the small business issuer and have:

b)     designed such internal control over financial reporting, or caused such internal control over financial reporting to be designed under my 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;

affected, or is reasonably likely to materially affect, the small business issuer’s internal control over the financial report; and





5.     I have disclosed, based on my most recent evaluation of internal control over financial reporting, to the registrant’s auditors and the board of directors:





a)     all significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting that 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.
