(c) Information to Be Provided by the Trustee. The Trustee shall (i) on or before the final Business Day of each month, provide to the Seller, in writing, such information regarding the Trustee as is requested for the purpose of compliance with Item 1117 of Regulation AB, and (ii) as promptly as practicable following notice to or discovery by the Trustee of any changes to such information, provide to the Seller, in writing, such updated information.
