Incorporated;

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

     financial reporting; and

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 (or persons performing the equivalent functions):

          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 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
     controls over financial reporting.
