                  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
         Company, 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. Designed such internal control over financial reporting, or
         caused such internal control over financial reporting to be designed
         under our supervision, to provide reasonable assurance regarding the
         reliability of financial reporting and the preparation of financial
         statements for external purposes in accordance with generally accepted
         accounting principles;

                  c. Evaluated the effectiveness of the company'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 report based on such evaluations;
         and

                  d. Disclosed in this report any change in the company's
         internal control over financial reporting that occurred during the

         reasonably likely to materially affect, the company's internal control
         over financial reporting.

         5. The company's other certifying officer(s) and I have disclosed,
based on our most recent evaluation of internal controls over financial
reporting, to the company's auditors and the audit committee of company's Board
of Directors (or persons performing the equivalent function):

                  a. 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 company'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
         company's internal controls over financial reporting.
