| 4.     |   | I am responsible  for reviewing the activities performed by the servicer under the pooling and  servicing, or similar, agreement and based upon my knowledge and the annual  compliance review required under that agreement, and except as disclosed in  the reports, the servicer has fulfilled its obligations under that agreement;  and                                                                                                    |
|   |   |                                                                                                                                                                                                                                                                                                                                                                                                                                            |
| 5.     |   | The reports  disclose all significant deficiencies relating to the servicer’s compliance  with the minimum servicing standards based upon the report provided by an  independent public accountant, after conducting a review in compliance with  the Uniform Single Attestation Program for Mortgage Bankers or similar  procedure, as set forth in the pooling and servicing, or similar, agreement,  that is included in these reports. |
