(a) Except as provided in subsections (c) and (g) of this Section 2.05, the registered holder of all of the Series 2048 Bonds shall be The Depository Trust Company (“DTC”) and such Series 2048 Bonds shall be registered in the name of Cede & Co., as nominee for DTC. Payment of principal of, premium, if any, and interest on any Series 2048 Bonds registered in the name of Cede & Co. shall be made by transfer of New York Federal or equivalent immediately available funds with respect to the Series 2048 Bonds to the account of

Cede & Co. on each such payment date for the Series 2048 Bonds at the address indicated for Cede & Co. in the Bond Register kept by the Trustee.

(b) The Series 2048 Bonds shall be initially issued in the form of one or more separate single authenticated fully registered certificates in the aggregate principal amount of the Series 2048 Bonds. Upon initial issuance, the ownership of such Series 2048 Bonds shall be registered in the Bond Register kept by the Trustee in the name of Cede & Co., as nominee of DTC. The Trustee and the Company may treat DTC (or its nominee) as the sole and exclusive registered holder of the Series 2048 Bonds registered in its name for the purposes of payment of the principal of, premium, if any, and interest on the Series 2048 Bonds and of giving any notice permitted or required to be given to registered holders under the Indenture, except as provided in Subsection 2.05(g) below; and neither the Trustee nor the Company shall be affected by any notice to the contrary. Neither the Trustee nor the Company shall have any responsibility or obligation to any of DTC’s participants (each a “Participant”), any person claiming a beneficial ownership in the Series 2048 Bonds under or through DTC or any Participant (each a “Beneficial Owner”), or any other person that is not shown on the Bond Register maintained by the Trustee as being a registered holder, with respect to (1) the accuracy of any records maintained by DTC or any Participant; (2) the payment of DTC or any Participant of any amount in respect of the principal of, premium, if any, or interest on the Series 2048 Bonds; (3) the delivery by DTC or any Participant of any notice to any Beneficial Owner which is permitted or required to be given to registered holders under the Indenture of the Series 2048 Bonds; (4) the selection of the Beneficial Owners to receive payment in the event of any partial redemption of the Series 2048 Bonds; or (5) any consent given or other action taken by DTC as bondholder. The Trustee shall pay all principal of, premium, if any, and interest on the Series 2048 Bonds registered in the name of Cede & Co. only to or “upon the order of” (as that term is used in the Uniform Commercial Code as adopted in Wisconsin and New York) DTC, and all such payments shall be valid and effective to fully satisfy and discharge the Company’s obligations with respect to the principal of, premium, if any, and interest on such Series 2048 Bonds to the extent of the sum or sums so paid. Except as otherwise provided in Subsections 2.05(c) and (g) below, no person other than DTC shall receive authenticated bond certificates evidencing the obligation of the Company to make payments of principal of, premium, if any, and interest on the Series 2048 Bonds. Upon delivery by DTC to the Trustee of written notice to the effect that DTC has determined to substitute a new nominee in place of Cede & Co., and subject to the provisions of the Indenture with respect to transfers of bonds, the word “Cede & Co.” in this Supplemental Trust Indenture shall refer to such new nominee of DTC.

(c) If the Company in its discretion determines that it is in the best interest of the Beneficial Owners that they be able to obtain bond certificates for the Series 2048 Bonds or there shall have occurred and be continuing a Completed Default with respect to the Series 2048 Bonds, the Company may notify DTC and the Trustee, whereupon DTC will notify the Participants of the availability through DTC of bond certificates. In such event, the Trustee shall issue, transfer and exchange bond certificates as requested by DTC in appropriate amounts pursuant to Article II of the Indenture and Section 2.03 of this Supplemental Trust Indenture. The Company shall pay all costs in connection with the production of bond certificates if the Company makes such a determination under this Subsection 2.05(c). DTC may determine to discontinue providing its services with respect to the Series 2048 Bonds at any time by giving written notice to the Company and the Trustee and discharging its responsibilities with respect thereto under applicable law.

Under such circumstances (if there is no successor book-entry depository), the Company and the Trustee shall be obligated (at the sole cost and expense of the Company) to deliver bond certificates as described in this Supplemental Trust Indenture. If bond certificates are issued, the provisions of the Indenture shall apply to, among other things, the transfer and exchange of such certificates and the method of payment of principal of, premium, if any, and interest on such certificates. Whenever DTC requests the Company and the Trustee to do so, the Company will direct the Trustee (at the sole cost and expense of the Company) to cooperate with DTC in taking appropriate action after reasonable notice (1) to make available one or more separate certificates evidencing the Series 2048 Bonds to any Participant or (2) to arrange for another book-entry depository to maintain custody of certificates evidencing the Series 2048 Bonds registered in the name of such depository or its nominee. Any successor book-entry depository must be a clearing agency registered with the Securities and Exchange Commission pursuant to Section 17A of the Securities Exchange Act of 1934, as amended, and must enter into an agreement with the Company and the Trustee agreeing to act as the depository and clearing agency for the Series 2048 Bonds (except as provided in Subsection 2.05(g) below). After such agreement has become effective, DTC shall present the Series 2048 Bonds for registration of transfer in accordance with Section 2.11 of the Indenture, and the Trustee shall register them in the name of the successor book-entry depository or its nominee and all references thereafter to DTC shall be to such successor book-entry depository. If a successor book-entry depository has not accepted such position before the effective date of DTC’s termination of its services, the book-entry system shall automatically terminate and may not be reinstated without the consent of all registered holders of the Series 2048 Bonds.

(d) Notwithstanding any other provision of this Supplemental Trust Indenture to the contrary, so long as any Series 2048 Bonds are registered in the name of Cede & Co., as nominee of DTC, all payments with respect to the principal of, premium, if any, and interest on such Series 2048 Bonds and all notices with respect to such Series 2048 Bonds shall be made and given, respectively, to DTC as provided in the blanket representation letter among DTC, the Company and the Trustee. The Trustee is hereby authorized and directed to comply with all terms of the representation letter.

(e) In connection with any notice or other communication to be provided pursuant to the Indenture for the Series 2048 Bonds by the Company or the Trustee with respect to any consent or other action to be taken by the registered holders of the Series 2048 Bonds, the Company or the Trustee, as the case may be, shall seek to establish a record date to the extent permitted by the Indenture for such consent or other action and give DTC notice of such record date not less than fifteen (15) calendar days in advance of such record date to the extent possible. Such notice to DTC shall be given only when DTC is the sole registered holder.

(f) NEITHER THE COMPANY NOR THE TRUSTEE WILL HAVE ANY RESPONSIBILITY OR OBLIGATIONS TO THE PARTICIPANTS OR THE BENEFICIAL OWNERS WITH RESPECT TO (1) THE ACCURACY OF ANY RECORDS MAINTAINED BY DTC OR ANY PARTICIPANT; (2) THE PAYMENT BY DTC OR ANY PARTICIPANT OF ANY AMOUNT DUE TO ANY BENEFICIAL OWNER IN RESPECT OF THE PRINCIPAL OF, PREMIUM, IF ANY, OR INTEREST ON THE SERIES 2048 BONDS; (3) THE DELIVERY BY DTC OR ANY PARTICIPANT OF ANY NOTICE TO ANY BENEFICIAL OWNER WHICH IS REQUIRED OR PERMITTED UNDER THE TERMS OF THE

INDENTURE TO BE GIVEN TO REGISTERED HOLDERS; (4) THE SELECTION OF THE BENEFICIAL OWNERS TO RECEIVE PAYMENT IN THE EVENT OF ANY PARTIAL REDEMPTION OF THE SERIES 2048 BONDS; OR (5) ANY CONSENT GIVEN OR OTHER ACTION TAKEN BY DTC AS A REGISTERED HOLDER.

SO LONG AS CEDE & CO. IS THE REGISTERED HOLDER OF THE SERIES 2048 BONDS AS NOMINEE OF DTC, REFERENCES HEREIN TO REGISTERED HOLDERS OF THE SERIES 2048 BONDS SHALL MEAN CEDE & CO. AND SHALL NOT MEAN THE BENEFICIAL OWNERS OF THE SERIES 2048 BONDS NOR THE PARTICIPANTS.

(g) The Company, in its sole discretion, may terminate the services of DTC with respect to the Series 2048 Bonds if the Company determines that: (i) DTC (x) is unable to discharge its responsibilities with respect to the Series 2048 Bonds or (y) at any time ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended; or (ii) there shall have occurred and be continuing a Completed Default with respect to the Series 2048 Bonds. The Company, in its sole discretion, may terminate the services of DTC with respect to the Series 2048 Bonds if the Company determines that a continuation of the requirement that all of the outstanding Series 2048 Bonds be registered with the registration books kept by the Trustee in the name of Cede & Co., as nominee of DTC, is not in the best interest of the Beneficial Owners of the Series 2048 Bonds. After such event and if no substitute book-entry depository is appointed by the Company, bond certificates will be delivered as described in the Indenture.

(h) Upon the termination of the services of DTC with respect to the Series 2048 Bonds pursuant to subsections (c) or (g) of this Section 2.05 after which no substitute book-entry depository is appointed, the Series 2048 Bonds shall be registered in whatever name or names registered holders transferring or exchanging the Series 2048 Bonds shall designate in accordance with the provisions of the Indenture.

(c) Any authenticating agent at any time may resign by giving written notice of resignation to the Trustee and to the Company. The Trustee may at any time, and upon written request of the Company to the Trustee shall, terminate the agency of any authenticating agent by giving written notice of termination to such authenticating agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time any authenticating agent shall cease to be eligible in accordance with the provisions of this Section 3.02, the Trustee, unless otherwise requested in writing by the Company, promptly shall appoint a successor authenticating agent, which shall be acceptable to the Company. Any successor authenticating agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers, duties and responsibilities of its predecessor hereunder, with like effect as if originally named. No successor authenticating agent shall be appointed unless eligible under the provisions of this Section 3.02.
