	 Corporation;

     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

	 respects the financial condition, results of operations and cash

     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

	    of the disclosure controls and procedures, as of the end
	    of the period covered by this report based on such
	    evaluation; and

	    (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 (the
	    registrant's fourth fiscal quarter in the case of an
	    annual report) 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(s) 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 (or persons
	 performing the equivalent functions):

	    (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.
