3. The Issuer shall maintain in the Borough of Manhattan, The City of New York, an established place of business or agency where Securities may be surrendered for registration of transfer or exchange. The Issuer has initially appointed the Fiscal Agent acting through its corporate trust office in Chicago, and at its agent’s office in the Borough of Manhattan, The City of New York, as its agent for such purpose and the Issuer has agreed to cause to be kept at such offices a register in which, subject to such reasonable regulations as it may prescribe, the Issuer will provide for the registration of Securities and of transfers of Securities. The Issuer reserves the right to vary or terminate the appointment of the Fiscal Agent as security registrar or of any Transfer Agent or to appoint additional or other registrars or Transfer Agents or to approve any change in the office through which any security registrar or any Transfer Agent acts, provided that there will at all times be a security registrar or agent thereof in the Borough of Manhattan, The City of New York. Registered holders of the Securities will receive notice of any such change.

The transfer of a Security is registrable on the aforementioned register upon surrender of such Security at the corporate trust office of the Fiscal Agent or the office of the agent of the Fiscal Agent or any Transfer Agent duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Issuer and the Fiscal Agent duly executed by, the registered holder thereof or such holder’s attorney duly authorized in writing.

At the option of the registered holder upon request confirmed in writing, Securities may be exchanged for Securities of any authorized denominations and of a like tenor, form and aggregate principal amount upon surrender of the Securities to be exchanged at the office of any Transfer Agent or at the corporate trust office of the Fiscal Agent or agent thereof. Whenever any Securities are so surrendered for exchange, the Issuer shall execute, and the Fiscal Agent shall authenticate and deliver, the Securities which the registered holder making the exchange is entitled to receive. Any registration of transfer or exchange will be effected upon the Transfer Agent or the Fiscal Agent, as the case may be, being satisfied with the documents of title and identity of the person making the request and subject to such reasonable regulations as the Issuer may from time to time agree with the Transfer Agent and the Fiscal Agent.

All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Issuer evidencing the same debt, and entitled to the same benefits, as the Securities surrendered upon such registration of transfer or exchange. No service charge shall be made for any registration of transfer or exchange, but the Issuer may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this Security for registration of transfer, the Issuer, the Fiscal Agent and any agent of the Issuer or the Fiscal Agent may treat the person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Issuer, the Fiscal Agent nor any such agent shall be affected by notice to the contrary.

The Fiscal Agent shall apply the amounts so paid to it to the payment of such interest and principal in accordance with the terms of the Securities. Any monies paid by the Issuer to the Fiscal Agent for the payment of the principal of, premium, if any, or interest on any Securities and remaining unclaimed at the end of two years after such principal, premium, if any, or interest shall have become due and payable (whether at maturity or otherwise) shall then be repaid to the Issuer upon its written request, and



US-DOCS\108220951.14	A-9

upon such repayment all liability of the Fiscal Agent with respect thereto shall cease, without, however, limiting in any way any obligation the Issuer may have to pay the principal of, premium, if any, and interest on this Security as the same shall become due.

(b) In any case where the due date for the payment of the principal of, premium, if any, or interest on any Security shall be at any place of payment on a day on which banking institutions are authorized or obligated by law to close, then payment of principal, premium, if any, or interest need not be made on such date at such place but may be made on the next succeeding day at such place which is not a day on which banking institutions are authorized or obligated by law to close, with the same force and effect as if made on the date for such payment, and no interest shall accrue for the period after such date.

5. The Securities are subject to redemption upon not less than 30 or more than 60 days’ notice to the registered holders of such Securities, at any time, as a whole or in part, at the election of the Issuer, at a redemption price equal to the greater of: (i) 100% of the Principal Amount of the Securities being redeemed or (ii) the sum of the present values of the remaining scheduled payments of principal of and interest on the Securities being redeemed discounted to the redemption date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at a discount rate equal to the Treasury Yield plus 25 basis points, plus, for (i) or (ii) above, whichever is applicable, accrued interest on the Securities to the Redemption Date.

The Securities are also subject to redemption upon not less than 30 or more than 60 days’ notice to the registered holders of such Securities, at any time on or after July 15, 2048 (which is the date that is six months prior to the maturity date of the Securities), as a whole or in part, at the election of the Issuer, at a redemption price equal to 100% of the Principal Amount of the Securities being redeemed, plus accrued and unpaid interest on the Securities to the Redemption Date.

If fewer than all the Securities are to be redeemed, selection of Securities for redemption will be made (i) in the case of Securities held in definitive form, such selection will be by lot, and (ii) in the case of Securities in Global form, such selection by the U.S. Depository in accordance with its applicable procedures.

Unless the Issuer defaults in payment of the redemption price, from and after the Redemption Date, the Securities or portions thereof called for redemption will cease to bear interest, and the holders thereof will have no right in respect of such Securities except the right to receive the redemption price thereof.

[If this Security is a Global Security, insert—In the event of redemption of this Security in part only, the Fiscal Agent will reduce the Principal Amount hereof by endorsement on Schedule A hereto such that the Principal Amount shown on Schedule A after such endorsement will reflect only the unredeemed portion hereof.]

All Indebtedness for money borrowed or incurred by other persons which is directly guaranteed as to payment of principal by any corporation shall for all purposes of the Securities be deemed to be Indebtedness of such corporation, but no other contingent obligation of such corporation in respect of Indebtedness incurred by other persons shall for any purpose be deemed Indebtedness of such corporation.

US-DOCS\108220951.14	A-17

(ii) immediately after giving effect to such transaction and treating any indebtedness which becomes an obligation of the Issuer or any Subsidiary of it as a result of such transaction as having been incurred by the Issuer or any such Subsidiary at the time of such transaction, no event of default (as set forth in Paragraph 7), and no event which, with notice or lapse of time or both, would become such an event of default, shall have happened and be continuing;

(iii) if, as a result of any such consolidation or merger or such conveyance, transfer or lease, properties or assets of the Issuer or any Subsidiary of it would become subject to a mortgage, pledge, lien, security interest or other encumbrance which would not be permitted by Paragraph 8 hereof, the Issuer, or the Successor Person, as the case may be, shall take such steps as shall be necessary effectively to secure the Securities equally and ratably with (or prior to) all Indebtedness secured by such mortgage, pledge, lien, security interest or other encumbrance; and

(iv) the Issuer has delivered to the Fiscal Agent an Officers’ Certificate and a written opinion or opinions of counsel satisfactory to the Fiscal Agent (who may be counsel to the Issuer), stating that such consolidation, merger, conveyance, transfer or lease and such amendment to the Fiscal Agency Agreement comply with this Paragraph 9 and that all conditions precedent herein provided for relating to such transaction have been complied with.

(b) Upon any such consolidation or merger, or any conveyance, transfer or lease of the properties and assets of the Issuer substantially as an entirety in accordance with Paragraph 9(a), the Successor Person shall succeed to, and be substituted for, and may exercise every right and power of, the Issuer under the Fiscal Agency Agreement and the Securities with the same effect as if the Successor Person had been named as the Issuer in the Fiscal Agency Agreement and the Securities, and thereafter the Issuer, except in the case of a lease of its properties and assets, shall be released from its liability as obligor on any of the Securities and under the Fiscal Agency Agreement.

9. Section 8 of the Fiscal Agency Agreement, which requires the Issuer to provide registered holders of Securities or, in the case of clauses (a) and (b) thereof, designated prospective purchasers of Securities with certain information and an Officers’ Certificate, is hereby incorporated mutatis mutandis by reference herein.

10. Until the date that is one year from the last date of issuance of any Securities issued pursuant to the Fiscal Agency Agreement, the Issuer will not, and will not permit any of its “affiliates” (as defined under Rule 144 under the Act or any successor provision thereto) to, resell any Securities which constitute “restricted securities” under Rule 144 that have been reacquired by any of them.

11. If any mutilated Security is surrendered to the Fiscal Agent, the Issuer shall execute, and the Fiscal Agent shall authenticate and deliver in exchange therefor, a new Security of like tenor and principal amount, bearing a number not contemporaneously outstanding.



US-DOCS\108220951.14	A-18

If there be delivered to the Issuer and the Fiscal Agent (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of each of them harmless, then, in the absence of notice to the Issuer or the Fiscal Agent that such Security has been acquired by a bona fide purchaser, the Issuer shall execute, and upon its written request the Fiscal Agent shall authenticate and deliver in lieu of any such destroyed, lost or stolen Security a new Security of like tenor and principal amount and bearing a number not contemporaneously outstanding.

Upon the issuance of any new Security under this Paragraph 12, the Issuer may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and the expenses of the Fiscal Agent) connected therewith.

Every new Security issued pursuant to this Paragraph 12 in lieu of any destroyed, lost or stolen Security, shall constitute an original additional contractual obligation of the Issuer, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone.

Any new Security delivered pursuant to this Paragraph 12 shall be so dated that neither gain nor loss in interest shall result from such exchange.

The provisions of this Paragraph 12 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

12. Section 12 of the Fiscal Agency Agreement, which Section is hereby incorporated mutatis mutandis by reference herein, provides that, with certain exceptions as therein provided and by written consent of a majority in the principal amount of all Outstanding Securities, the Issuer and the Fiscal Agent may modify, amend or supplement the Fiscal Agency Agreement or the terms of the Securities or may give consents or waivers or take other actions with respect thereto. Any such modification, amendment, supplement, consent, waiver or other action shall be conclusive and binding on the holder of this Security and on all future holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange heretofore or in lieu hereof, whether or not notation thereof is made upon this Security.

13. No reference herein to the Fiscal Agency Agreement and no provision of this Security or of the Fiscal Agency Agreement shall alter or impair the obligation of the Issuer, which



US-DOCS\108220951.14	A-19

is absolute and unconditional, to pay the principal of and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

14. This Security is subject to the provisions of Section 15 of the Fiscal Agency Agreement (which are incorporated mutatis mutandis by reference herein) which provide for the defeasance at any time of (i) the entire indebtedness of this Security or (ii) certain covenants and events of default, in each case upon compliance with certain conditions set forth therein.

6. We are acquiring the Bonds purchased by us for our own account or for one or more accounts (each of which is an institutional “accredited investor”) as to each of which we exercise sole investment discretion.

You and the Company are entitled to rely upon this letter and are irrevocably authorized to produce this letter or a copy hereof to any interested party in any administrative or legal proceedings or official inquiry with respect to the matters covered hereby.
