Inc.
|
|
2.
|
Based on my
knowledge, this quarterly 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

|
|
3.
|
Based on my

4.
|
The
registrant's other certifying officer and I are responsible for
establishing and maintaining disclosure controls and procedures (as

control over financial reporting (as defined in Exchange Act Rules
13a-15(f) and 15d-15(f)) 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 is made known to us by others
within the registrant, particularly during the period in which this report
is being prepared;
|
|
b.
|
Designed such
internal control over financial reporting, or caused such internal control
over financial reporting to be designed under our supervision to provide
reasonable assurance regarding the reliability of financial reporting and
the preparation of financial statements for external purposes in
accordance with generally accepted accounting
principles;
|
|
c.
|
Evaluated the
effectiveness of the registrant's disclosure controls and procedures and
presented in this report our conclusions about the effectiveness of the

this report based on such evaluation;
and
|
|
d.
|
Disclosed in
this report any change in the registrant’s internal control over financial

affect, the registrant’s internal control over financial
reporting;
|
|
5.
|
The
registrant's other certifying officer 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 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.
