procedures (as defined in Exchange Act Rules 13a-14 and 15d-14)) and internal
controls over financial reporting (as defined in Exchange Act Rules 13a-15(f)

information relating to the small business issuer, including its consolidated
subsidiaries, is made known to me by others within those entities, particularly
during the period in which this report is being prepared;

internal controls over financial reporting to be designed under my supervision,

controls and procedures and presented in this annual report my 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

control over financial reporting that occurred during the small business

likely to affect, the small business issuer's internal control over financial
reporting;

 5. I have disclosed, based on my most recent evaluation of internal control
over financial reporting, to the small business issuer's auditors and the audit
committee of small business issuer's board of directors (or persons performing
the equivalent functions):


a. all significant deficiencies and material weaknesses in the design or
operation of internal controls which are reasonably likely to adversely affect
the small business issuer'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 small business issuer's internal
control over financial reporting.
