SECOND AMENDMENT
TO THE
SECOND AMENDED AND RESTATED
LIMITED LIABILITY COMPANY AGREEMENT
OF
KAR Holdings II, LLC

This Second Amendment to the Second Amended and Restated Limited Liability Company Agreement of KAR Holdings II, LLC (this “Amendment”), effective as of December 15, 2009, amends the Second Amended and Restated Limited Liability Company Agreement of KAR Holdings II, LLC, dated April 20, 2007, as amended by the First Amendment thereto, dated December 10, 2009 (as the same may be amended from time to time, the “Agreement”). Capitalized terms used but not otherwise defined herein shall have the meanings given such terms in the Agreement.

WHEREAS, the undersigned, constituting all of the Investor Members of the Company, desire to amend the Agreement to make certain modifications to the treatment of the Class B Common Units.

NOW THEREFORE, in accordance with Section 14.10 of the Agreement and for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, and intending to be legally bound, the undersigned, constituting all of the Investor Members, hereby agree as follows:

1. Amendment.

(a) Section 9.1(d) of the Agreement is hereby amended and restated to read in its entirety as follows:

“(d) Notwithstanding anything to the contrary contained in this Agreement, if on any IAAI Dilution Calculation Date, there exists any IAAI Rollover Dilution Amounts, then with respect to the cash distribution under Section 9.1(b) that occurs on the date immediately following such IAAI Dilution Calculation Date (x) the aggregate amount of cash distributions to holders of Class A Common Units shall be deemed to be increased by the amount of the IAAI Rollover Dilution Amount on such date and (y) the aggregate amount actually distributed to Axle LLC in respect of its Class B Common Units will be reduced (each reduction, an “IAAI Dilution Reduction”) by the IAAI Rollover Dilution Amount on such date. The IAAI Rollover Dilution Amount shall be reduced dollar-for-dollar for any IAAI Dilution Reductions until the IAAI Rollover Dilution Amount is reduced to zero; provided, however, in the event that, on any IAAI Dilution Calculation Date, any Excess Tax Benefit exists, then no adjustment to such distribution shall be made under clause (x) and (y) above and the amount of the Excess Tax Benefit shall reduce, on a dollar-for-dollar basis, the IAAI Rollover Dilution Amount calculated on the next IAAI Dilution Calculation Date; it being understood that the amount of the Excess Tax Benefit shall be reduced, on a dollar-for-dollar basis, as the IAAI Rollover Dilution

Amount is reduced through the application of this sentence and no IAAI Rollover Dilution Amount shall exist if and to the extent the amount of the Excess Tax Benefit is greater than zero. Exhibit B hereto contains illustrative examples, with different assumptions as described therein, of the intended mechanics for how the IAAI Dilution Reduction (and related definitions) are intended to occur (the “IAAI Dilution Illustrative Example”). Notwithstanding anything to the contrary contained herein, the Members acknowledge and agree that any inconsistencies between the provisions of this Agreement and the IAAI Dilution Illustrative Example shall be resolved in favor of the IAAI Dilution Illustrative Example.

(b) Section 15.1 of the Agreement is hereby amended to include the following defined terms, in the appropriate alphabetical order:

“Adjusted Fully Diluted KAR Shares” means, as of any IAAI Dilution Calculation Date, a number of shares of Common Stock of KAR Auction Services equal to the total number of shares of Common Stock of KAR Auction Services issued and outstanding immediately prior to such IAAI Dilution Calculation Date plus the number of shares of Common Stock of KAR Auction Services equal to the Assumed IAAI Option Exercised Shares as of such IAAI Dilution Calculation Date.
