4. The Trust'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 Trust and have:

5. The Trust's other certifying officer(s) and I have disclosed, based on
our most recent evaluation of internal control over financial reporting, to the
Trust's auditors and the audit committee of the Trust'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 Trust's ability to record, process,
summarize and report financial information; and
