internal
control
over
financial

The registrant’s
other certifying
officer
and I

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
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.
