Automotive Finance Canada Inc. (“AFCI”), a subsidiary of KAR Auction Services, Inc. (the “Company”), and the Company have entered into an Amended and Restated Receivables Purchase Agreement (as amended, the “Receivables Purchase Agreement”), dated as of May 24, 2011, with BNY Trust Company of Canada, in its capacity as trustee of Precision Trust, a Canadian multi-seller conduit administered by BMO Nesbitt Burns Inc. (the “Trust”). Pursuant to the Receivables Purchase Agreement, AFCI sells undivided interests in certain eligible Canadian dollar denominated finance receivables to the Trust on a revolving basis.

The finance receivables sold and a cash reserve of 1 or 3 percent of the finance receivables sold serve as security for the obligations to the Trust. The amount of the cash reserve depends on circumstances which are set forth in the Receivables Purchase Agreement. After the occurrence of a termination event, as defined in the Receivables Purchase Agreement, the Trust has discretion to liquidate the receivables under the transaction documents as its primary remedy. Termination events include, among other things, breaches of representations and warranties; failures to perform covenants and other obligations as seller or servicer; violations of financial covenants related to AFCI, its direct parent, Automotive Finance Corporation (“AFC”), or the Company (including, among others, limits on the amount of debt AFCI can incur, minimum levels of tangible net worth of AFCI and AFC, and certain financial covenants contained in the Company’s senior secured credit agreement); defaults in payment of other indebtedness of the Company, AFC or AFCI; violation of certain covenants related to the performance of the receivables portfolio; the occurrence of a material adverse change in the collectability of the receivables or the business, operations, property or financial condition of AFCI; certain changes in control of AFCI or AFC; and certain bankruptcy events with respect to AFCI.

The following provides a brief description of the amendments effected by the Receivables Purchase Agreement that are material to the Company. Certain of the provisions described below are subject to an order from the Securities and Exchange Commission granting confidential treatment to certain of the information included in the Receivables Purchase Agreement.

BMO Nesbitt Burns Inc. or certain of its affiliates (“BMO”):

BMO received or will receive customary fees and expenses for its services in the various capacities described above.
