and have:

     a) Designed such disclosure controls and procedures, or caused such
     disclosure controls and procedures to be designed under our supervision, to

     within those entities, particularly during the period in which this report
     is being prepared;

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