|-- | --------------------------------------------------------------------------------------------------------------------

|2. | Based
on my knowledge, this report does not contain any untrue statement of a
          material fact or omit to state a material fact necessary to make the statements

          for, the periods presented in this report;
|-- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|4. | The
registrants other certifying officers and I are responsible for
          establishing and maintaining disclosure controls and procedures (as defined in

          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,
including its consolidated                     subsidiaries, is made known to us by
others within those entities, 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;

Evaluated
the effectiveness of the registrants disclosure controls and
                    procedures and presented in this report our conclusions about the
effectiveness                     of the disclosure controls and procedures, as of the
end of the period covered                     by this report based on such evaluation;
and
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (d)
Disclosed
in this report any change in the registrants internal control
                    over financial reporting that occurred during the period covered by
the report                     that has materially affected, or is reasonably likely to
materially affect, the                     Companys internal control over financial
reporting.
| | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|5. | The
registrants other certifying officers 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 function):
|-- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (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
