and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for
the issuer and have:

a)  Designed such disclosure controls and procedures, or caused such
disclosure controls and procedures to be designed under my supervision, to
ensure that material 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;

issuers internal control over financial reporting; and

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 the small business issuer's board of directors (or

operation of internal control over financial reporting which are reasonably





likely to adversely affect the small business issuers ability to record,
process, summarize and report financial information;  and

employees who have a significant role in the small business issuer's internal
control over financial reporting.
