Each party repeats to the other party the representations and warranties set forth in the Master Confirmation and in the Agreement (as defined in the Master Confirmation) (as if the Amendment and Restatement Date, the Second Amendment and Restatement Date and the Third Amendment and Restatement Date were the Trade Date, the date the parties entered into a Transaction and the date of the Master Confirmation).
