|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

               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;

               over financial reporting that occurred during the registrants most recent
               fiscal quarter (the registrants fourth fiscal quarter in the case of an
               annual report) that has materially affected, or is reasonably likely to
               materially affect, the registrants internal control over financial
               reporting; and
|-- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|5. |  | The registrants other certifying officer(s) 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 the 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.
