A certified copy of a by-law or of a resolution of the appropriate governing body of the Issuing Entity (or, as appropriate, a trustee on behalf of the Issuing Entity) may be received and accepted by the Custodian as conclusive evidence of the authority of any such officer to act and may be considered as in full force and effect until receipt of written notice to the contrary. Such instructions may be general or specific in terms.

6. Indemnification by the Custodian. The Custodian agrees to indemnify the Depositor, the Issuing Entity and each trustee for any and all liabilities, obligations, losses, damage, payments, costs or expenses of any kind whatsoever that may be imposed on, incurred or asserted against the Depositor, the Issuing Entity or any such trustee as the result of any act or omission in any way relating to the maintenance and custody by the Custodian of the Receivable Files described herein; provided, however, that the Custodian shall not be liable to the Depositor, the Issuing Entity or any such trustee, respectively, for any portion of any such amount resulting from the willful misfeasance, bad faith or negligence of the Depositor, the Issuing Entity or any such trustee, respectively.

7. Advice of Counsel. The Custodian, the Depositor and, upon execution of the Basic Documents, the Issuing Entity further agree that the Custodian shall be entitled to rely and act upon advice of counsel with respect to its performance hereunder and shall be without liability for any action reasonably taken pursuant to such advice, provided that such action is not in violation of applicable federal or state law.
