|    | (b)                                        |  | Designed such        internal control over financial reporting, or caused such internal        control over financial reporting to be designed under our supervision,        to provide reasonableness 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        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 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 |
