                     the Investment Company Act of 1940) for the registrant and
                     have:

                  a) designed such disclosure controls and procedures 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 as of a date within 90 days prior
                     to the filing date of this report (the "Evaluation Date");

                  5. The registrant's other certifying officers and I have
                     disclosed, based on our most recent evaluation, to the
                     registrant's auditors and the audit committee of the
                     registrant's board of directors (or persons performing the
                     equivalent functions):

                                       21



                  a) all significant deficiencies in the design or operation of
                     internal controls which could adversely affect the
                     registrant's ability to record, process, summarize, and
                     report financial data and have identified for the
                     registrant's auditors any material weaknesses in internal
                     controls; and

                  b) any fraud, whether or not material, that involves
                     management or other employees who have a significant role
                     in the registrant's internal controls; and

                  6. The registrant's other certifying officers and I have
                     indicated in this 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 our most recent evaluation,
                     including any corrective actions with regard to significant
                     deficiencies and material weaknesses.
