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

quarterly  report  whether or not there  were  significant  changes in  internal
controls or in other factors that could  significantly  affect internal controls
subsequent to the date of my most recent  evaluation,  including any  corrective
actions with regard to significant deficiencies and material weaknesses.
