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

| | (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 quarterly report is being prepared;

               over financial reporting that occurred during the registrants most recent
               fiscal quarter that has materially affected, or is reasonably likely to
               materially affect, the registrants internal control over financial
               reporting; and ;

          directors (or persons performing the equivalent functions):
|-- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (a) | all significant deficiencies 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
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

               financial reporting.
