In connection with such exchange, the Escrow Issuer shall deliver to the Trustee an Officer’s Certificate and instruction to decrease the principal amount of, and cancel, the Regulation S Temporary Global Note and increase the principal amount of the Regulation S Permanent Global Note in a like amount and the Trustee shall take such actions without receipt of an Opinion of Counsel.
