    The small business issuers other certifying officer(s) and I are responsible for

Exchange Act Rules 13a-15(f) and 15d-15(f)) for the small business issuer and have:
 a.
    
    Designed such disclosure controls and procedures, or caused such disclosure
controls and procedures to be designed under our supervision, to ensure that material
information relating to the small business issuer, including its consolidated
subsidiaries, is made known to us by others within those entities, particularly during
the period in which this report is being prepared;
 b.

accounting principals;
 c.

    Disclosed in this report any change in the small business issuers internal control
over financial reporting that occurred during the small business issuers most recent

annual report) that has materially affected, or is reasonably likely to materially
affect, the small business issuers internal control over financial reporting; and
 5.
    
    The small business issuers other certifying officer(s) and I have disclosed, based on our
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 persons performing the equivalent functions):

    All significant deficiencies and material weaknesses in the design or operation of
internal controls over financial reporting 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 controls over financial
reporting.
