(a)         Designed
such disclosure controls and procedures, or caused such disclosure controls and

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;

summarize and report financial information; and

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.
