[Issue description (“The Securities”)]

Ladies and Gentlemen:

     This letter sets forth our understanding with respect to certain matters relating to the Securities. Agent shall act as trustee, paying agent, fiscal agent, or other such agent of Issuer with respect to the Securities. The Securities have been issued pursuant to a trust indenture, trust agreement, pooling and servicing agreement or other such document authorizing the issuance of the Securities dated November 3, 2004 (the “Document”). [“Underwriter/ Placement Agent”]**

is distributing the Securities through The Depository Trust Company (“DTC”).

               To induce DTC to accept the Securities as eligible for deposit at DTC, and to act in accordance with its Rules with respect to the Securities, Issuer and Agent make the following representations to DTC:

               1. Prior to closing on the Securities on November 3, 2004 there shall be deposited with DTC one or more Security certificates registered in the name of DTC’s nominee, Cede & Co., for each stated maturity of the Securities in the face amounts set forth on Schedule A hereto, the total of which represents 100% of the principal amount of such Securities. If however, the aggregate principal amount of any maturity exceeds $500 million, one certificate shall be issued with respect to each $500 million of principal amount and an additional certificate shall be issued with respect to any remaining principal amount. Each Security certificate shall bear the following legend:

     Unless this certificate is presented by an authorized representative of The Depository Trust Company, a New York corporation (“DTC”), to Issuer or its agent for registration of transfer, exchange, or payment, and any certificate issued is registered in the name of Cede & Co. or in such other name as is requested by an authorized representative of DTC (and any payment is made to Cede & Co. or to such other entity as is requested by an authorized representative of DTC), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the registered owner hereof, Cede & Co., has an interest herein.

Issuer represents:

               The Security certificate(s) shall remain in Agent’s custody as a “Balance Certificate” subject to the provisions of the Balance Certificate Agreement between Agent and DTC currently in effect.

               On each day on which Agent is open for business and on which it receives an instruction originated by a DTC participant (“Participant”) through DTC’s Deposit/Withdrawal at Custodian (“DWAC”) system to increase the Participant’s account by a specified number of Securities (a “Deposit Instruction”), Agent shall, no later than 6:30 p.m. (Eastern Time) that day, either approve or cancel the Deposit Instruction through the DWAC system.

               On each day on which Agent is open for business and on which it receives an instruction originated by Participant through the DWAC system to decrease the Participant’s account by a specified number of Securities (a “Withdrawal Instruction”), Agent shall, no later than 6:30 pm. (Eastern Time) that day, either approve or cancel the Withdrawal Instruction through the DWAC system.

2

               Agent agrees that its approval of a Deposit or Withdrawal Instruction shall be deemed to be the receipt by DTC of a new reissued or reregistered certificated Security on registration of transfer to the name of Cede & Co. for the quantity of Securities evidenced by the Balance Certificate after the Deposit or Withdrawal Instruction is effected.

               2. Issuer: (a) understands that DTC has no Obligation to, and will not, communicate to its Participants or to any person having an interest in the Securities any information contained in the Security certificate(s); and (b) acknowledges that neither DTC’s Participants nor any person having an interest in the Securities shall be deemed to have notice of the provisions of the Security certificates by virtue of submission of such certificate(s) to DTC.

               3. In the event of any solicitation of consents from or voting by holders of the Securities, Issuer or Agent shall establish a record date for such purposes (with no provision for revocation of consents or votes by subsequent holders) and shall send notice of such record date to DTC no fewer than 15 calendar days in advance of such record date.
