(“FAREISI”) or an affiliate thereof (the “Acquiror”) and (ii) amendment and restatement of certain agreements relating to FARES.

NON-BINDING PROVISIONS

The following numbered paragraphs of this letter agreement (collectively, the “Non-Binding Provisions”) reflect our current mutual understanding of the matters described herein, but each party acknowledges that the Non-Binding Provisions are not intended to create or constitute any legally binding obligation between Experian and First American, and neither First American nor Experian shall have any liability to the other with respect to the Non-Binding Provisions until fully-integrated amended and restated definitive agreements and other related documents (collectively, the “Definitive Agreements”) are prepared, authorized, executed and delivered by and between the relevant parties. If the Definitive Agreements are not prepared, authorized, executed and delivered for any reason, neither First American nor Experian shall have any liability to the other based upon, arising from or relating to the Non-Binding Provisions. Each party acknowledges that it will not take action or refrain from taking action in reliance on any of the Non-Binding Provisions or the negotiation thereof, and that any such reliance would be at its own risk. No subsequent oral agreement or consent of the parties (including partial performance) related to the Non-Binding Provisions shall be deemed to impose any such obligation or liability.

1. Data Trace/Data Tree Transaction. The Data Tree and Data Trace businesses will be distributed by FARES to FAREISI, will be purchased by the Acquiror or will otherwise be transferred to the Acquiror upon the occurrence of the closing under the Definitive Agreements. For its indirect interest in the Data Tree and Data Trace businesses Experian will receive at the time of the transfer of such businesses an amount in cash equal to $48,010,000.
