Additional Termination Events: The following Additional Termination Events will apply to UBS AG: 1. Ratings Event. If a Ratings Event (as defined below) has occurred and UBS AG has not complied with the requirements set forth in the succeeding paragraph within the 30 day time period specified therein, then an Additional Termination Event shall have occurred with respect to UBS AG and UBS AG shall be the sole Affected Party with respect to such an Additional Termination Event.

("Moody's) within thirty (30) days of such Ratings Event and subject to written confirmation from Fitch and Moody's that delivery of such collateral in the context of such downgrade will not result in a withdrawal, qualification or downgrade of the then current ratings assigned to the Certificates. For the avoidance of doubt, a downgrade of the rating on Wells Fargo Mortgage Backed Securities 2006-6 Trust, Mortgage Pass-Through Certificates, Series 2006-6, Class I-A-22 (the "Certificates") could occur in the event that UBS AG does not post sufficient collateral.

Swap Disclosure Event. If upon the occurrence of a Swap Disclosure Event (as defined in paragraph (xxiii) above), UBS AG has not, within 5 business days after such Swap Disclosure Event complied with any of the provisions set forth in paragraph (xxiii) above, then an Additional Termination Event shall have occurred with respect to UBS AG with UBS AG as the sole Affected Party with respect to such Additional Termination Event. Transfer, Amendment and Assignment: No transfer, amendment, waiver, supplement, assignment or other modification of this Transaction (other than the pledge of this Transaction to the Master Servicer pursuant to the Pooling and Servicing Agreement) shall be permitted by either party unless Moody's and Fitch have been provided notice of the same and confirm in writing (including by facsimile transmission) that they will not downgrade, qualify, withdraw or otherwise modify its then-current rating of the Certificates; provided however that except with respect to a transfer at the direction of UBS, nothing in this provision shall impose any obligation on UBS to give notice to any rating agency.

"Permitted Security Interest" means the collateral assignment by the Counterparty of the Cap Collateral to the Master Servicer pursuant to the Pooling and Servicing Agreement, and the granting to the Master Servicer of a security interest in the Cap Collateral pursuant to the Pooling and Servicing Agreement.
