The Securities Intermediary, the Issuer, the Servicer and the Secured Party agree that the Securities Intermediary shall comply with any entitlement order originated by the Secured Party without further consent of the Issuer or the Servicer. The Servicer is hereby authorized to (i) direct the withdrawal of funds from the Subject Accounts to make distributions in accordance with the Sale and Servicing Agreement and the Indenture and (ii) direct the transfer or redemption of any financial asset relating to the Subject Accounts, in each case until and unless such authorization is revoked in writing by the Secured Party.

(b) If the Secured Party notifies the Securities Intermediary that the Secured Party will exercise exclusive control over the Subject Accounts (a “notice of exclusive control”), then the Securities Intermediary shall not comply with any contrary or otherwise inconsistent instructions or other directions concerning the Subject Accounts originated by the Issuer or the Servicer unless and until such notice of exclusive control is withdrawn by the Secured Party. The Secured Party shall only give such notice of exclusive control upon the occurrence and during the continuance of an Event of Default and the acceleration of the payment of principal and interest on the Notes in accordance with the Indenture (without the related declaration of acceleration and its consequences having been rescinded or annulled), after expiration of the related period specified in Article V of the Indenture limiting actions in respect of such Event of Default.

Section 3.2. No Control by Issuer or Third Parties Concerning Subject Accounts. The Securities Intermediary shall not comply with any instructions of the Issuer or the Servicer (except to the extent permitted under Section 3.1(a)) concerning the Subject Accounts (including any order that is originated by the Issuer or the Servicer and that would require the Securities Intermediary to make a free delivery of Subject Accounts to the Issuer or any other person). Additionally, the Securities Intermediary shall not agree with any third party (other than the Secured Party) that the Securities Intermediary will comply with orders originated by such third party concerning the Subject Accounts.

Section 3.3. Perfection of Security Interests in Subject Accounts.

With respect to any proceeds of the Account Property that constitute a Deposit Account, it is intended for purposes of Article 9 of the UCC that (i) the Securities Intermediary is the bank with which the Deposit Account is maintained and the Issuer is the bank’s customer with respect to the Deposit Account, and (ii) the Issuer, the Secured Party, the Servicer and the Securities Intermediary agree that the Securities Intermediary will comply with instructions originated by the Secured Party directing disposition of funds in the Deposit Accounts without further consent of the Issuer or the Servicer.

(h) The Securities Intermediary shall not be deemed to have notice or knowledge of any Event of Default or any other default under any other Transaction Document unless an Responsible Officer of the Securities Intermediary has actual knowledge or Securities Intermediary shall have received written notice thereof. In the absence of such actual knowledge or receipt of such notice, the Securities Intermediary may conclusively assume that none of such events have occurred and the Securities Intermediary shall not have any obligation or duty to determine whether any Event of Default or any other default under any other Transaction Document has occurred or is continuing.
