ARTICLE III

RIGHTS OF THE SECURED PARTY

Section 3.1 Control of Accounts by Secured Party.

(a) Subject to Section 3.1(b), the Intermediary shall comply with any entitlement order originated by the Secured Party, the Servicer or the Transferor. The Intermediary, the Transferor and the Secured Party agree that the Intermediary shall comply with any entitlement order originated by the Secured Party without further consent of the Transferor or the Servicer. The Servicer is hereby authorized to (i) direct the withdrawal of funds from the Accounts to make distributions in accordance with the PSA and any amendment or supplement thereof, and (ii) direct the transfer or redemption of any financial asset relating to the Accounts, in each case until and unless such authorization is revoked in writing by the Secured Party. The Transferor is hereby authorized to update Schedule 1 (with written notice to each of the parties hereto) in order to add additional accounts as such accounts are created and opened pursuant to the PSA.

(b) If the Secured Party notifies the Intermediary that the Secured Party will exercise exclusive control over the Accounts (a “notice of exclusive control”), then the Intermediary shall not comply with any contrary or otherwise inconsistent instructions or other directions concerning the Accounts originated by the Transferor or the Servicer unless and until such notice of exclusive control is withdrawn by the Secured Party.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 Amortization Event and the acceleration of the payment of principal and interest on the Certificates in accordance with the PSA and any amendment or supplement thereof (without the related declaration of acceleration and its consequences having been rescinded or annulled), after expiration of the related period specified in the PSA and any amendment or supplement thereof limiting actions in respect of such Amortization Event.

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

Section 3.3 Perfection of Security Interests in Accounts. It is intended that the first priority security interest of the Secured Party in the Accounts be perfected by control of the Accounts under Sections 8-106(d)(2), 9-106(a) and 9-314(a) of the UCC. In addition, it is intended for purposes of Articles 8 and 9 of the UCC that (i) the Transferor be deemed to be the related “entitlement holder”, (ii) the Intermediary be deemed to be the related “securities intermediary”, (iii) all such property held by the Intermediary in the Accounts and all rights of the Transferor against the Intermediary arising out of such property, including any free credit balances, be deemed to be “financial assets”, and (iv) the Secured Party be deemed to have “control” of such Accounts under Section 8-106(d)(2) of the UCC with respect to the first priority security interest therein granted to the Secured Party pursuant to the PSA. 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 Intermediary is the bank with which the deposit account is maintained and the Transferor is the bank’s customer with respect to the deposit account, and (ii) the Transferor, the Secured Party, the Servicer and the Intermediary agree that the Intermediary will comply with instructions originated by the Secured Party directing disposition of funds in the deposit accounts without further consent of the Transferor or the Servicer.

Section 3.4 Notices of Adverse Claims.

party hereto under this Agreement, the Certificates or the PSA (other than the Transferor) shall be extinguished and shall not thereafter be reinstated. No recourse shall be had against any principal, director, officer, employee, beneficiary, shareholder, partner, member, trustee, agent or affiliate of the Transferor or any person owning, directly or indirectly, any legal or beneficial interest in the Transferor, or any successors or assigns of any of the foregoing (the “Exculpated Parties”) for the payment of any amounts payable hereunder or thereunder.

Section 5.14 Limitations on Liability of Intermediary.

(a) This Agreement shall not subject the Intermediary to any duty, obligation or liability except as is expressly set forth herein.

(b) The Intermediary shall be protected in acting or refraining from acting upon any written notice, certificate, instruction, request or other paper or document, as to the due execution thereof and the validity and effectiveness of the provisions thereof and as to the truth of any information therein contained, which the Intermediary in good faith believes to be genuine.

(c) The Intermediary may consult with and obtain advice from counsel, accountants or other experts of its own choice in the event of any dispute or question as to the construction of any provision hereof or otherwise in connection with its duties hereunder, and any action taken or omitted by the Intermediary in reasonable reliance upon such advice shall be full justification and protection to it. The Intermediary shall not be liable for any error of judgment or for any act done or step taken or omitted except in the case of its willful misconduct, bad faith or negligence.

(g) The Intermediary may rely upon the contents of any notice, consent, instruction or other communication or document from the Master Trust Trustee, for the benefit of the Secured Parties, the Transferor or the Servicer that the Intermediary believes in good faith to be genuine and from the proper Person, without any further duty of inquiry or independent investigation on its part.

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

(i) No provision of this Agreement or any Transaction Document shall be construed to require the Intermediary to perform, supervise, monitor or accept any responsibility for the performance of, the obligations of the Transferor or the Servicer hereunder or under any other Transaction Document or any Person other than itself under any Transaction Document.

(j) The Intermediary shall not be liable for any delays in performance for causes beyond its reasonable control, including acts of declared or undeclared war (including acts of terrorism), public disorder, rebellion, sabotage, fire, flood, epidemic, pandemic, landslide, lightning, fire, hurricane, earthquake, flood, strike, restriction by civil or military authority in their sovereign or contractual capacities, transportation failure, loss or malfunctions of communications or computer (software and hardware) services, power line or other utility failures or interruptions, or inability to obtain labor.
