              CORP.;

2.            Based on my knowledge, this report does not contain any untrue
              statement of a material fact or omit to state a material fact
              necessary to make the statements made, in light of the
              circumstances under which such statements were made, not
              misleading with respect to the period covered by this report;

3.            Based on my knowledge, the financial statements, and other
              financial information included in this report, fairly present in
              all material respects the financial condition, results of

              periods presented in this report;

4.            The registrant's other certifying officer(s) and I are responsible
              for establishing and maintaining disclosure controls and
              procedures (as defined in Exchange Act Rules 13a-15(e) and
              15d-15(e)) for the registrant 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 registrant, 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) evaluated the effectiveness of the registrant's disclosure
                 controls and procedures and presented in this report our
                 conclusions about the effectiveness of the disclosure controls
                 and procedures, as of the end of the period covered by this

              c) disclosed in this report any change in the registrant's
                 internal control over financial reporting that occurred during
                 the registrant's most recent fiscal quarter that has materially
                 affected, or is reasonably likely to materially affect, the
                 registrant's internal control over financial reporting; and

     5.       The registrant's other certifying officer and I have disclosed,
              based on our most recent evaluation of internal control over
              financial reporting, to the registrant's auditors and the audit
              committee of the registrant's board of directors:

              a) all significant deficiencies and material weaknesses in the
                 design or operation of internal control over financial
                 reporting which are reasonably likely to adversely affect the
                 registrant'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 registrant's
                 internal control over financial reporting.
