                 New York corporation ("DTC"), to the Company or its agent for
                 registration of transfer, exchange or payment, and any

                 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 holder hereof, Cede & Co., has an

         Securities] in definitive certificated form, the Global Security

         (collectively, the "Depository"), as the sole and exclusive owner of
         the [Senior Debt Securities] registered in its name for the purposes
         of payment of the principal of or interest on the [Senior Debt
         Securities], giving any notice permitted or required to be given to
         holders of the [Senior Debt Securities] under the Indenture or this
         Series _____ Supplement, registering the transfer of the [Senior Debt
         Securities], obtaining any consent or other action to be taken by
         holders of the [Senior Debt Securities] and for all other purposes
         whatsoever, and neither the Trustee nor the Company shall be affected
         by any notice to the contrary.  Neither the Company nor the Trustee
         shall have any responsibility or obligation to any Participant, any

         the accuracy of any records maintained by the Depository or any
         Participant; (ii) the payment by the Depository to any Participant of
         any amount in respect of the

         principal of or interest on the [Senior Debt Securities]; or (iii) the
         payment by any Participant to any owner of a beneficial ownership
         interest in the [Senior Debt Securities] in respect of the principal
         of or interest on the [Senior Debt Securities].  The Trustee shall pay
         all principal of and interest on the [Senior Debt Securities] only to
         or upon the order of the registered holder or holders of the [Senior
         Debt Securities], as shown in the Senior Debt Security Register, and
         all such payments shall be valid and effective to fully satisfy and
         discharge the Company's obligations with respect to the principal of
         and interest on the [Senior Debt Securities] to the extent of the sum
         or sums so paid.  No person other than a holder of the [Senior Debt
         Securities], as shown in the Senior Debt Security Register, shall
         receive an authenticated [Senior Debt Security] evidencing the
         obligation of the Company to make payment of the principal of and
         interest on the [Senior Debt Securities] pursuant to the Indenture and
         this Series ____ Supplement.  Upon delivery by DTC to the Trustee of
         written notice to the effect that DTC has determined to substitute a
         new nominee for Cede & Co., and subject to the provisions of the
         Indenture and this Series _____ Supplement, the word "Cede & Co.", as
         used in this Series _____ Supplement, shall refer to each new nominee
         of DTC.

                 (d)      In the event that after the occurrence of an Event of
         Default that has not been cured or waived, holders of a majority in
         aggregate principal amount of the beneficial interests in the [Senior
         Debt Securities], as reflected in the books and records of the
         Depository, notify the Trustee, through the Depository or any
         Participant, that the continuation of the Book-Entry System is no
         longer in the best interests of such holders of beneficial interests
         in the [Senior Debt Securities], then the Trustee shall notify the
         Depository and the Company, and the Depository will notify the
         Participants of the availability through the Depository of definitive
         certificated [Senior Debt Securities].  In such event, the Company
         shall execute, and the Trustee, upon receipt of a written order of the
         Company, signed by its President or a Vice President and by its

         writing by the Depository in the aggregate principal amount of the
         Global Security and in exchange for such Global Security.

                 (e)      If at any time the Depository notifies the Company
         that it is unwilling or unable to continue as Depository for the
         [Senior Debt Securities] or if at any time the Depository shall no
         longer be registered as a clearing agency in good standing under the
         Securities Exchange Act of 1934, as

   7
         amended, or other applicable statute or regulation, the Company shall
         appoint a successor Depository with respect to the [Senior Debt
         Securities].  If a successor Depository for the [Senior Debt
         Securities] is not appointed by the Company within 90 days after the
         Company receives such notice or becomes aware of such condition, the
         Company will execute, and the Trustee, upon receipt of an Issuer Order
         for the authentication and delivery of definitive certificated [Senior
         Debt Securities], will authenticate and deliver [Senior Debt
         Securities] in definitive certificated form, in any authorized
         denominations, all pursuant to the provisions of the Indenture, to the
         person or persons specified to the Trustee in writing by the
         Depository in the aggregate principal amount of the Global Security
         and in exchange for such Global Security.

                 (f)      The Company may at any time and in its sole
         discretion determine that the [Senior Debt Securities] shall no longer
         be represented by a Global Security.  In such event the Company will
         execute, and the Trustee, upon receipt of an Issuer Order for the
         authentication and delivery of definitive certificated [Senior Debt
         Securities], will authenticate and deliver [Senior Debt Securities] in
         definitive certificated form, in any authorized denominations, all
         pursuant to the provisions of the Indenture, to the person or persons
         specified to the Trustee in writing by the Depository in the aggregate
         principal amount of the Global Security and in exchange for such
         Global Security.

                 (g)      Upon the exchange of a Global Security for [Senior
         Debt Securities] in definitive certificated form, in authorized
         denominations, such Global Security shall be cancelled by the Trustee.

                 (h)      Whenever the Depository requests the Company and the
         Trustee to do so, the Trustee and the Company will cooperate with the
         Depository in taking appropriate action after reasonable notice to (i)
