ULC receives a refund (or such refund is applied to reduce other taxes payable by Sheppard Canada Holding N.S. ULC) of the Canadian VAT from the Canada Revenue Agency (or other applicable taxing authorities) or, to the extent that the Canadian VAT paid by Sheppard Canada Holding N.S. ULC to Aon Hewitt Inc. reduces the net tax remittable for Canadian VAT purposes by Sheppard Canada Holding N.S. ULC for its applicable Canadian VAT reporting period that includes the Closing Date, within 7 business days after the filing due date of Sheppard Canada Holding N.S. ULC’s Canadian VAT Tax Return in which it claims a credit for such Canadian VAT. Seller Parent and Buyer agree that they will cause Aon Hewitt Inc. and Sheppard Canada Holding N.S.
