For the avoidance of doubt, each outstanding Transaction is a continuing transaction and has not been, and shall not be, considered terminated in any respect. From and after the date hereof, (a) UBS 1285 shall be a party to the Repurchase Agreement and Pricing Letter and shall have the rights and obligations of Assignor as Buyer thereunder and shall be bound by the provisions thereof and (b) Assignor shall relinquish its rights and be released from its obligations under the Repurchase Agreement and Pricing Letter and all future and outstanding Transactions thereunder except for those Obligations of Seller to Assignor (including, without limitation, any indemnification obligations) that survive which shall continue for the benefit of the Assignor.
