	    statement of a material fact or omit to state a material fact

	    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 operations
	    and cash flows of the registrant as of, and for, the 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

	       (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

	    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

	       financial information; and

	       (b)  Any fraud, whether or not material, that involves
