 a)
    
    Designed such disclosure controls and procedures, or
caused such disclosure controls and procedures to be

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 annual report is being prepared;b)
    
    Designed such internal control over financial reporting,

generally accepted accounting principles;c)

disclosure controls and procedures and presented in this

andd)
    
    Disclosed in this report any change in the registrants

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 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; andb)
    
    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.
