of its affiliates, directors, officers, shareholders, agents or employees will be liable to the Servicer, the Issuer or any other Person, except by reason of acts or omissions by the Collateral Administrator constituting bad faith, willful misfeasance, gross negligence or reckless disregard of the Collateral Administrator’s duties hereunder. The Collateral Administrator shall in no event have any liability for the actions or omissions of the Issuer, the Servicer or any other Person, and shall have no liability for any inaccuracy or error in any duty performed or information or report provided by it that results from or is caused by inaccurate, untimely or incomplete information or data received by it from the Issuer, the Servicer or another Person (other than the Trustee, if the same entity shall be serving as Trustee and Collateral Administrator hereunder) except to the extent that such inaccuracies or errors are caused by the Collateral Administrator’s own bad faith, willful misfeasance, gross negligence or reckless disregard of its duties hereunder.

The Collateral Administrator shall not be liable for any action taken by it in good faith and reasonably believed by it to be within the discretion or powers conferred upon it, or taken by it pursuant to any direction or instruction by which it is governed hereunder, or omitted to be taken by it by reason of the lack of direction or instruction required hereby for such action. The Collateral Administrator shall not be bound to make any investigation into the facts or matters stated in any certificate, report or other document; provided, however, that, if the form thereof is prescribed by this Agreement, the Collateral Administrator shall examine the same to determine whether it conforms on its face to the requirements hereof.

Nothing herein shall impose or imply any duty or obligation on the part of the Collateral Administrator to verify, investigate or audit any such information or data (except to the extent

5

any such information provided is patently incorrect or inconsistent with any proximally received information or instruction, in which case the Collateral Administrator shall investigate any such information), or to determine or monitor on an independent basis whether any issuer of or Obligor under the Collateral is in default or in compliance with the underlying documents governing or securing such securities, from time to time, the role of the Collateral Administrator hereunder being solely to perform certain mathematical computations and data comparisons as provided herein.

(e)Without limiting the generality of any terms of this Section 4, the Collateral Administrator shall have no liability for any failure, inability or unwillingness on the part of the Servicer or Issuer (or Trustee, if not the same Person as the Collateral Administrator) to provide accurate and complete information on a timely basis to the Collateral Administrator, or otherwise on the part of any such party to comply with the terms of this Agreement, the Indenture, or the Sale and Servicing Agreement, and shall have no liability for any inaccuracy or error in the performance or observance on the Collateral Administrator’s part of any of its duties hereunder that is caused by or results from any such inaccurate, incomplete or untimely information received by it, or other failure on the part of any such other party to comply with the terms hereof.

Nothing herein shall obligate the Collateral Administrator to determine independently the characteristics of any Collateral, including whether any item of Collateral is a Margin Stock, a Current Pay Loan, a Charged-Off Loan, a Delinquent Loan, a Permitted PIK Loan, or a Credit Impaired Loan, it being understood that any such determination shall be based
