hold harmless the Remainco Indemnitees from and against any and all Indemnifiable Losses of the Remainco Indemnitees to the extent relating to WM Mexico Business, the Mexico Transferred Assets and the WM Mexico Assumed Liabilities incurred by any Remainco Indemnitees from and following Closing, excluding (x) the Regulatory Expenses and (y) any Indemnifiable Losses to the extent resulting from or arising out of any material and intentional breach of Remainco’s obligations under the Repurchase Agreement and (2) from and after the Repurchase Transactions Closing, the Parties shall treat the WM Mexico Business, the Mexico Transferred Assets and the Mexico Assumed Liabilities as if they were Transferred to or Assumed by Spinco or members of the Spinco Group, as the case may be, as of the Spinco Distribution Date and prior to the Spinco Distribution.”
