The aggregate principal amount of any Regulation S Global Security may from time to time be increased or decreased by adjustments made on the records of the Trustee, as provided in Section 209 hereof, which adjustments shall be conclusive as to the aggregate principal amount of any such Global Security. The Restricted Global Security and Regulation S Global Security are sometimes collectively referred to herein as the "GLOBAL SECURITIES."

(e) Series C Bonds issued pursuant to Section 208(c) in exchange for interests in a Global Security shall be issued substantially in the form of Exhibit B hereto in definitive, fully registered form without interest coupons, but shall not bear the legend for Global Securities in Section 208(b) (the "DEFINITIVE SECURITIES"). Except as provided herein, owners of beneficial interests in Global Securities shall not be entitled to physical delivery of Definitive Securities.

Section 203. Execution and Authentication. The Trustee, upon a Company Order and pursuant to the terms of the Original Indenture and this Third Supplemental Indenture, shall authenticate and deliver Series C Bonds for original issue in an initial aggregate principal amount of $100,000,000. Such Company Order shall specify the amount of the Series C Bonds to be authenticated, the date on which the original issue of Series C Bonds is to be authenticated and the aggregate principal amount of Series C Bonds outstanding on the date of authentication. All of the Series C Bonds issued under the Indenture shall be treated as a single series for all purposes under the Indenture, including, without limitation, waivers, amendments, and offers to purchase.

Section 204. Depositary for Global Securities. The Depositary for the Series C Bonds initially shall be DTC.

Section 205. Place of Payment. The Place of Payment in respect of the Series C Bonds will be at the principal office or agency of the Company in The City of New York, State of New York or at the office or agency of the Trustee in The City of New York, State of New York which, at the date hereof, is located at 101 Barclay Street, New York, New York 10286.

Section 206. Legends.

(a) All Series C Bonds issued pursuant to this Third Supplemental Indenture shall be "RESTRICTED SECURITIES" and shall bear a legend to the following effect (the "RESTRICTED LEGEND") except as permitted by the following paragraph (b) or (c), as appropriate:

"THIS SECURITY (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND THIS SECURITY MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. EACH PURCHASER OF THIS SECURITY IS HEREBY NOTIFIED THAT THE SELLER OF THIS SECURITY MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF
SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER.

THE HOLDER OF THIS SECURITY AGREES FOR THE BENEFIT OF THE COMPANY THAT (A) THIS SECURITY MAY BE OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (I) IN THE UNITED STATES TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (II) OUTSIDE THE UNITED STATES IN

AN OFFSHORE TRANSACTION IN ACCORDANCE WITH RULE 904 UNDER THE SECURITIES ACT,
(III) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER (IF AVAILABLE), (IV) IN ACCORDANCE WITH ANOTHER EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT (BASED UPON AN OPINION OF COUNSEL ACCEPTABLE TO THE COMPANY IF THE COMPANY SO REQUESTS) OR
(V) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, IN EACH OF CASES (I) THROUGH (V) IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES, AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER OF THIS SECURITY FROM IT OF THE RESALE RESTRICTIONS REFERRED TO IN (A) ABOVE."

Each Restricted Definitive Security shall bear the following legend on the face thereof:

"IN CONNECTION WITH ANY TRANSFER, THE HOLDER WILL DELIVER TO THE REGISTRAR AND TRANSFER AGENT SUCH CERTIFICATES AND OTHER INFORMATION AS SUCH TRANSFER AGENT MAY REASONABLY REQUIRE TO CONFIRM THAT THE TRANSFER COMPLIES WITH THE FOREGOING RESTRICTIONS."

Each Temporary Regulation S Global Security shall bear the following legend on the face thereof:

"EXCEPT AS SET FORTH BELOW, BENEFICIAL OWNERSHIP INTERESTS IN THIS TEMPORARY REGULATION S GLOBAL SECURITY WILL NOT BE EXCHANGEABLE FOR INTERESTS IN THE PERMANENT REGULATION S GLOBAL SECURITY OR ANY OTHER SECURITY REPRESENTING AN INTEREST IN THE SECURITIES REPRESENTED HEREBY WHICH DO NOT CONTAIN A LEGEND CONTAINING RESTRICTIONS ON TRANSFER, UNTIL THE EXPIRATION OF THE "40-DAY DISTRIBUTION COMPLIANCE PERIOD" (WITHIN THE MEANING OF RULE 903(B)(2) OF REGULATION S UNDER THE SECURITIES ACT) AND THEN ONLY UPON CERTIFICATION IN FORM REASONABLY SATISFACTORY TO THE TRUSTEE THAT SUCH BENEFICIAL INTERESTS ARE OWNED EITHER BY NON-U.S. PERSONS OR U.S. PERSONS WHO PURCHASED SUCH INTERESTS IN A TRANSACTION THAT DID NOT REQUIRE REGISTRATION UNDER THE SECURITIES ACT. DURING SUCH 40-DAY DISTRIBUTION COMPLIANCE PERIOD, BENEFICIAL OWNERSHIP IN THIS TEMPORARY REGULATION S GLOBAL SECURITY MAY ONLY BE SOLD, PLEDGED OR TRANSFERRED THROUGH EUROCLEAR S.A./N.V. OR CLEARSTREAM BANKING, SOCIETE ANONYME AND ONLY (1) TO THE COMPANY, (2) WITHIN THE UNITED STATES TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (3) OUTSIDE THE UNITED STATES IN A TRANSACTION IN ACCORDANCE WITH RULE 904 UNDER THE SECURITIES ACT OR (4) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, IN EACH OF CASES (1) THROUGH (4) IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES AND OTHER JURISDICTIONS. HOLDERS OF INTERESTS IN THIS TEMPORARY REGULATIONS S GLOBAL SECURITY WILL NOTIFY ANY PURCHASER OF THIS SECURITY OF THE RESALE RESTRICTIONS REFERRED TO ABOVE, IF THEN APPLICABLE.

BENEFICIAL INTERESTS IN THIS TEMPORARY REGULATION S GLOBAL SECURITY MAY BE EXCHANGED FOR INTERESTS IN A RESTRICTED GLOBAL SECURITY ONLY IF (1) SUCH EXCHANGE OCCURS IN CONNECTION WITH A TRANSFER OF THE SECURITIES IN COMPLIANCE WITH RULE 144A, AND (2) THE TRANSFEROR OF THE TEMPORARY REGULATION S GLOBAL SECURITY FIRST DELIVERS TO THE TRUSTEE A WRITTEN CERTIFICATE (IN THE FORM ATTACHED TO THIS CERTIFICATE) TO THE EFFECT THAT THE REGULATION S GLOBAL SECURITY IS BEING TRANSFERRED (A) TO A PERSON WHO THE TRANSFEROR REASONABLY BELIEVES TO BE A QUALIFIED INSTITUTIONAL BUYER WITHIN THE MEANING OF RULE 144A, (B) TO A PERSON WHO IS PURCHASING FOR ITS OWN ACCOUNT OR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A AND (C) IN ACCORDANCE WITH ALL APPLICABLE SECURITIES LAWS OF THE STATES OF THE UNITED STATES AND OTHER JURISDICTIONS.

BENEFICIAL INTERESTS IN A RESTRICTED GLOBAL SECURITY MAY BE TRANSFERRED TO A PERSON WHO TAKES DELIVERY IN THE FORM OF AN INTEREST IN THE REGULATION S GLOBAL SECURITY, WHETHER BEFORE OR AFTER THE EXPIRATION OF THE 40-DAY DISTRIBUTION COMPLIANCE PERIOD, ONLY IF THE TRANSFEROR FIRST DELIVERS TO THE TRUSTEE A WRITTEN CERTIFICATE (IN THE FORM ATTACHED TO THIS CERTIFICATE) TO THE EFFECT THAT IF SUCH TRANSFER IS BEING MADE IN ACCORDANCE WITH RULE 903 OR 904 OF REGULATION S OR RULE 144 (IF AVAILABLE) AND THAT, IF SUCH TRANSFER OCCURS PRIOR TO THE EXPIRATION OF THE 40-DAY DISTRIBUTION COMPLIANCE PERIOD, THE INTEREST TRANSFERRED WILL BE HELD IMMEDIATELY THEREAFTER THROUGH EUROCLEAR S.A./N.V. OR CLEARSTREAM BANKING, SOCIETE ANONYME."

(b) Upon any sale or transfer of a Restricted Security pursuant to Rule 144 under the Securities Act, the Depositary shall, subject to approval by the Company and the provisions of Section 3.05 of the Original Indenture, permit the Holder thereof to request the issuance of a Series C Bond that does not bear one or more of the legends set forth above and rescind any restrictions on the transfer of such Restricted Security, if the sale or exchange was made in reliance on Rule 144 and the Holder certifies to that effect in writing to the Depositary.

(c) Upon a sale or transfer after the expiration of the Distribution Compliance Period of any Series C Bonds acquired pursuant to Regulation S, all requirements that such Series C Bonds bear the Restricted Legend shall cease to apply (but requirements requiring such Series C Bonds to be in global form and bear the global legend in Section 208 shall continue to apply).

Section 207. Restrictions on Transfer and Exchange of Series C Bonds. All Series C Bonds issued upon any registration of transfer or exchange of Series C Bonds shall be valid obligations of the Company, evidencing the same interest therein, and entitled to the same benefits under the Original Indenture and this Third Supplemental Indenture, as the Series C Bonds surrendered upon such registration of transfer or exchange.

A Holder may transfer a Series C Bond, or request that a Series C Bond be exchanged for Series C Bonds in authorized denominations and in an aggregate principal amount equal to the principal amount of such Series C Bond surrendered for exchange of other authorized denominations, by surrender of such Series C Bonds to the Trustee with the form of transfer notice thereon duly completed and executed, and otherwise complying with the terms of the Original Indenture and this Third Supplemental Indenture, including providing evidence of compliance with any restrictions on transfer, in form satisfactory to the Company, the Trustee and the Security Registrar. No such transfer shall be effected until, and such transferee shall succeed to the rights of a Holder only upon, final acceptance and registration of the transfer by the Security Registrar in the Security Register. Prior to the registration of any transfer of a Series C Bond by a Holder as provided herein, the Company, the Security Registrar, the Paying Agent and the Trustee shall deem and treat the person in whose name the Series C Bond is registered on the Security Register as the absolute owner and holder thereof for the purpose of receiving payment of all amounts payable with respect to such Series C Bond and for all other purposes, and none of the Company, the Security Registrar, the Paying Agent or the Trustee shall be affected by any notice to the contrary. Furthermore, the Depositary shall, by acceptance of a Global Security, agree that transfers of beneficial interests in such Global Security may be effected only through a book-entry system maintained by the Depositary (or its agent) and that ownership of a beneficial interest in the Global Security shall be required to be reflected in a book-entry. When Series C Bonds are presented to the Security Registrar with a request to register the transfer thereof or to exchange them for other authorized denominations of a Series C Bond in a principal amount equal to the aggregate principal amount of Series C Bonds surrendered for exchange, the Security Registrar shall register the transfer or make the exchange as requested if its requirements for such transactions are met.

To permit registrations of transfers and exchanges in accordance with the terms, conditions and restrictions hereof, the Company shall execute, and the Trustee shall authenticate, Series C Bonds at the Security Registrar's request. No service charge shall be made to a Holder for any registration of transfer or exchange of Series C Bonds, but the Company may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer or exchange of Series C Bonds. All Series C Bonds surrendered for registration of transfer or exchange shall be cancelled by the Trustee in accordance with its then customary procedures.

Section 208. Book-Entry Provisions for Restricted Global Securities and Regulation S Global Securities.

(a) Members of, or participants in, DTC ("AGENT MEMBERS") shall have no rights under the Original Indenture, this Third Supplemental Indenture and the Series C Bonds with respect to any Global Security held on their behalf by DTC, or The Bank of New York Trust Company, N.A., as its custodian, and DTC may be treated by the Company, the Trustee and any agent of the Trustee as the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Trustee from giving effect to any written certification, proxy or other authorization furnished by DTC or shall impair, as between DTC and its Agent Members, the operation of customary practices governing the exercise of the rights of a holder of any Global Security. Upon the issuance of any Global Security, the Security Registrar or its duly appointed agent shall record DTC as the registered holder of such Global Security.

Transfers of any Global Security shall be limited to transfers of such Restricted Global Security or Regulation S Global Security in whole, but not in part, to the Depositary. Each Global Security shall bear the following legend:

"UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY OR SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (AND ANY PAYMENT HEREON MADE TO CEDE & CO.), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN. TRANSFERS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS IN WHOLE BUT NOT IN PART, TO NOMINEES OF THE DEPOSITORY TRUST COMPANY OR TO A SUCCESSOR THEREOF OR SUCH SUCCESSOR'S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE RESTRICTIONS SET FORTH IN THE INDENTURE REFERRED TO ON THE REVERSE HEREOF."

Beneficial interests in the Restricted Global Security and any Regulation S Global Security may be transferred in accordance with the rules and procedures of DTC and the provisions of Section 209.

(c) Beneficial interests in a Restricted Global Security or a Regulation S Global Security shall be delivered to all beneficial owners thereof in the form of Rule 144A Definitive Securities ("RULE 144A DEFINITIVE SECURITIES") or Regulation S Definitive Securities ("REGULATION S DEFINITIVE SECURITIES"), as the case may be, if (i) DTC notifies the Trustee that it is unwilling or unable to continue as Depositary for such Restricted Global Security or Regulation S Global Security, as the case may be, and a successor depositary is not appointed by the Trustee within 90 days of such notice, and (ii) after the occurrence and during the continuance of an Event of Default, owners of beneficial interests in a Global Security with a principal amount aggregating not less than a majority of the outstanding principal amount of the Global Security advise the Trustee, the Company and DTC through Agent Members in writing that the continuation of a book-entry system through DTC or its successor is no longer in their best interests.

(d) Any beneficial interest in one of the Global Securities that is transferred to a Person who takes delivery in the form of an interest in another Global Security will, upon such transfer, cease to be an interest in such Global Security and become an interest in the other Global Security and, accordingly, will thereafter be subject to all transfer restrictions, if any, and other procedures applicable to beneficial interests in such other Global Security for as long as it remains such an interest.

(e) In connection with the transfer of an entire Restricted Global Security or an entire Regulation S Global Security to the beneficial owners thereof pursuant to paragraph (c) of this Section 208, such Restricted Global Security or Regulation S Global Security, as the case may be, shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall authenticate, to each beneficial owner

identified by DTC in exchange for its beneficial interest in such Restricted Global Security or Regulation S Global Security, as the case may be, an equal aggregate principal amount of Rule 144A Definitive Securities or Regulation S Definitive Securities, as the case may be, of authorized denominations. None of the Company, the Security Registrar, the Paying Agent or the Trustee shall be liable for any delay in delivery of such instructions and may conclusively rely on, and shall be protected in relying on, such registration instructions. Upon the issuance of Rule 144A Definitive Securities or Regulation S Definitive Securities, as the case may be, the Company and the Trustee shall recognize the Person in whose name the Rule 144A Definitive Securities or Regulation S Definitive Securities, as the case may be, are registered in the Security Register as Holders hereunder.

(f) Any Rule 144A Definitive Securities or Regulation S Definitive Securities, as the case may be, delivered in exchange for an interest in the Restricted Global Security pursuant to paragraph (c) of this Section 208 shall, except as otherwise provided by paragraph (d) of Section 209, bear the Restricted Legend.

(g) Prior to the expiration of the Distribution Compliance Period, any Regulation S Definitive Security delivered in exchange for an interest in a Regulation S Global Security pursuant to paragraph (c) of this Section 208 shall bear the Restricted Legend.

(h) The registered holder of any Restricted Global Security or Regulation S Global Security may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under the Original Indenture or this Third Supplemental Indenture or the Series C Bonds.

(i) Neither the Company nor the Trustee shall be liable if the Trustee or the Company is unable to locate a qualified successor clearing agency.

Section 209. Special Transfer Provisions. The following provisions shall also apply to the Series C Bonds:

(a) Transfers to QIBs. The following provisions shall apply with respect to the registration of any proposed transfer of a Series C Bond required to bear the Restricted Legend to a QIB (excluding Non-U.S. Persons):

(i) The Security Registrar shall register the transfer if such transfer is being made by a proposed transferor who has checked the box provided for on the form of Series C Bond stating, or has otherwise advised the Company, the Trustee and the Security Registrar in writing, that the sale has been made in compliance with the provisions of Rule 144A to a transferee who has signed the certification provided for on the form of Series C Bond stating, or has otherwise advised the Company, the Trustee and the Security Registrar in writing, that it is purchasing the Series C Bond for its own account or an account with respect to which it exercises sole investment discretion and that it, or the Person on whose behalf it is acting with respect to any such account, is a QIB within the meaning of Rule 144A, and is aware that the sale to it is being made in reliance on Rule 144A and acknowledges that it has received such information regarding the Company as it has requested pursuant to Rule 144A or has determined not to request such information and that it is aware that the transferor is relying upon its foregoing representations in order to claim the exemption from registration provided by Rule 144A.

(ii) Upon receipt by the Security Registrar of the documents required by clause (i) above and instructions given in accordance with DTC's and the Security Registrar's procedures therefor, the Security Registrar shall reflect on its books and records the date of such transfer and an increase in the principal amount of a Restricted Global Security in an amount equal to the principal amount of the interests in such Regulation S Global Security being transferred, and the Trustee shall decrease the amount of such Regulation S Global Security so transferred.

(b) Transfers of Interests in the Temporary Regulation S Global Security, the Permanent Regulation S Global Security or the Regulation S Definitive Securities.

(i) After the expiration of the Distribution Compliance Period, the Security Registrar shall register any transfer of interests in any Regulation S Global Security or Regulation S Definitive Security without requiring any additional certification.

(ii) Until the expiration of the Distribution Compliance Period, interests in the Temporary Regulation S Global Security may only be sold, pledged or transferred through Euroclear S.A./N.V. ("EUROCLEAR") or Clearstream Banking, Societe Anonyme ("CLEARSTREAM") (as indirect participants in the Depositary) or Agent Members acting for and on behalf of Euroclear and Clearstream only (x) for interests in a Permanent Regulation S Global Security and then only upon certification in form reasonably satisfactory to the Trustee that interests in such Temporary Regulation S Global Security are owned by either Non-U.S. Persons or U.S. Persons who purchased such interests in a transaction that did not require registration under the Securities Act or (y) for interests in the Restricted Global Security if the transferor first delivers to the Trustee a written transfer notice to the effect that the Series C Bonds are being transferred to a person (A) who the transferor reasonably believes to be a QIB; (B) purchasing for its own account or the account of a QIB in a transaction meeting the requirements of Rule 144A; and (C) in accordance with all applicable securities laws of the states of the United States and other jurisdictions.

(c) Transfers to Non-U.S. Persons at Any Time. The following provisions shall apply with respect to any registration of any transfer of a Series C Bond to a Non-U.S. Person:

(i) Prior to the expiration of the Distribution Compliance Period, the Security Registrar shall register any proposed transfer of a Series C Bond to a Non-U.S. Person upon receipt of a certificate substantially in the form set forth as Exhibit C hereto from the proposed transferor.

(ii) After the expiration of the Distribution Compliance Period, the Security Registrar shall register any proposed transfer to any Non-U.S. Person upon receipt of a certificate substantially in the form of Exhibit C from the proposed transferor. The Security Registrar shall promptly send a copy of such certificate to the Company.

(iii) Upon receipt by the Security Registrar of (x) the documents, if any, required by clause (ii) and (y) instructions in accordance with DTC's and the Security Registrar's procedures, the Security Registrar shall reflect on its books and records the date of such transfer and a decrease in the principal amount of such Restricted Global Security in an amount equal to the principal amount of the beneficial interest in such Restricted Global Security to be transferred, and, upon receipt by the Security Registrar of instructions given in accordance with DTC's and the Security Registrar's procedures, the Security Registrar shall reflect on its books and records the date and an increase in the principal amount of the Regulation S Global Security in an amount equal to the principal amount of the Restricted Global Security to be transferred, and the Trustee shall decrease the amount of such Restricted Global Security.

(d) Restricted Legend. Upon the transfer, exchange or replacement of Series C Bonds not bearing the Restricted Legend, the Security Registrar shall deliver Series C Bonds that do not bear the Restricted Legend. Upon the transfer, exchange or replacement of Series C Bonds bearing the Restricted Legend, the Security Registrar shall deliver only Series C Bonds that bear the Restricted Legend unless there is delivered to the Security Registrar an opinion of counsel to the effect that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act.

(e) General. By acceptance of any Series C Bond bearing the Restricted Legend, each Holder of such Series C Bond acknowledges the restrictions on transfer of such Series C Bond set forth in such Restricted Legend and otherwise in this Third Supplemental Indenture and agrees that it will transfer such Series C Bond only as provided in such Restricted Legend and otherwise in this Third Supplemental Indenture. In connection with any transfer of Series C Bonds, each Holder agrees by its acceptance of the Series C Bonds to furnish the Security Registrar or the Trustee such certifications, legal opinions or other information as either of them may reasonably require to confirm that such transfer is being made pursuant to an exemption from, or a transaction not subject to, the registration requirements of the Securities Act and in accordance with the terms and provisions of this Article Two; provided that the Security Registrar shall not be required to determine the sufficiency of any such certifications, legal opinions or other information.

Until such time as no Series C Bonds remain Outstanding, the Security Registrar shall retain copies of all letters, notices and other written communications received pursuant to Section 208 or this Section 209. The Trustee, if not the Security Registrar at such time, shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable written notice to the Security Registrar.

The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Third Supplemental Indenture or under applicable law with respect to any transfer of any interest in any Series C Bonds (including any transfers between or among Agent Members or beneficial owners of interests in any Global Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when required by the terms of, this Third Supplemental Indenture, and to examine the same to determine substantial compliance as to form with the requirements hereof.

In the event that any Global Security or any portion thereof is exchanged for Definitive Securities, such other Definitive Securities may be exchanged (by transfer or otherwise) for Definitive Securities or for beneficial interests in a Global Security (if any is then outstanding) only in accordance with procedures substantially consistent with this Article Two (including any certification requirements) and applicable procedures adopted by the Company and the Trustee.

Until definitive Series C Bonds are ready for delivery, the Company may use temporary Series C Bonds. Temporary Series C Bonds shall be substantially in the form of definitive Series C Bonds but may have variations that the Company considers appropriate for temporary Series C Bonds. Without unreasonable delay, the Company shall deliver definitive Series C Bonds in exchange for temporary Series C Bonds.

The Company may issue some or all of the Securities in temporary or permanent global form. The Company may issue a Global Security only to the Depositary. The Depositary may transfer a Global Security only to its nominee or to a successor Depositary. A Global Security shall represent the amount of Series C Bonds specified in the Global Security. A Global Security may have variations that the Depositary requires or that the Company considers appropriate for such a security.

Beneficial owners of part or all of a Global Security are subject to the rules of the Depository as in effect from time to time.

The Company, the Trustee and their agents shall not be responsible for any acts or omissions of a Depositary, for any Depositary records of beneficial ownership interests or for any transactions between or among the Depositary, Agent Members and beneficial owners.

The Company at any time may deliver Series C Bonds to the Trustee for cancellation. The Paying Agent, if not the Trustee, shall forward to the Trustee any Series C Bonds surrendered to them for payment or conversion. The Trustee shall cancel all Series C Bonds surrendered for registration of transfer, exchange, payment or cancellation and shall dispose of cancelled Series C Bonds according to its then customary practices. The Company may not issue new Series C Bonds to replace Series C Bonds that it has paid or which have been delivered to the Trustee for cancellation.

ARTICLE THREE

REDEMPTION

The Series C Bonds may be redeemed, in accordance with the procedures set forth in the Original Indenture, on not less than 30 nor more than 60 days' notice prior to the Redemption Date to the Holders, given as provided in the Original Indenture, as a whole or in part, at any time at the option of the Company, at a Redemption Price equal to the greater of (i) 100% of the principal amount of the Series C Bonds being redeemed and (ii) as determined by an Independent Investment Banker, the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such payments of interest accrued as of the Redemption Date) discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus, in each case, accrued and unpaid interest thereon to, but excluding, the Redemption Date; provided, however, that installments of interest on the Series C Bonds that are due and payable on an interest payment date falling on or prior to the relevant Redemption Date will be payable to the Holders of such Series C Bonds registered as such at the close of business on the relevant record date according to the terms and provisions of the Original Indenture.

In the event of a partial redemption of the Series C Bonds, the Company will issue new Series C Bonds for the unredeemed portion in the name of each Holder of the partially redeemed Series C Bonds.

If less than all of the Series C Bonds are to be redeemed, the Series C Bonds will be redeemed by lot, pro rata by the Trustee or by such method of selection as the Trustee shall deem fair and appropriate and which may, in any case, provide for the selection for redemption of Series C Bonds and portions of Series C Bonds in amounts of $1,000 or any integral multiples of $1,000 in excess thereof.

Unless the Company defaults in payment of the Redemption Price, the portion of Series C Bonds called for redemption will no longer accrue interest on and after the Redemption Date.

ARTICLE FOUR

MAINTENANCE AND RENEWAL

(a) The Company covenants and agrees that, so long as any of the Series C Bonds are Outstanding, the Company will expend during each calendar year, and certify to the Trustee in an Officer's Certificate, an amount not less than 2.00% of the average amount of depreciable property of the Company at the beginning and at the end of such calendar year for one or more of the following purposes:

(i) capital expenditures for the maintenance and repair of the utility properties of the Company subject to the Lien of the Original Indenture;

(ii) the construction or acquisition of Property Additions on which the Original Indenture is a first Lien, subject only to Permitted Liens and Prepaid Liens; or

(iii) the retirement, through purchase, payment or redemption, of Securities issued under and secured by the Indenture (including any future supplemental indenture pursuant to the Original Indenture).

(b) The term "amount of depreciable property" shall mean as of any date the amount of Property Additions included at such date on the books of the Company which is depreciable, as determined in accordance with generally accepted accounting principles in the United States. The average of the amount of depreciable property shall mean the arithmetical average of the amount of depreciable property at the beginning, and the amount thereof at the end, of such calendar year. Partial years shall be prorated.

If, in any calendar year, the required expenditures for the foregoing purposes are not made, the Company shall deposit with the Trustee on or before the first day of February next succeeding the close of such calendar year a sum in cash to the extent of any deficiency, after deducting (subject to the terms of the Indenture) any eligible credit for unused excess expenditures previously made for such purposes. Such cash may be applied to the redemption at the applicable Redemption Price, or to the repurchase, of Securities, or may be withdrawn to the extent of 100% of Property Additions.

(c) Excess expenditures in any calendar year may be used to comply with the requirements of any subsequent year or years and Property Additions may be certified to comply with the provisions of clause (b) above; provided, that Property Additions so used, and Securities retired through expenditures so used, cannot be used for other purposes under this Third Supplemental Indenture; provided, further that, (i) no Retired Securities or expenditures for Funded Property which shall have been made the basis for authentication of Securities or the release of Mortgaged Property or the withdrawal of deposited cash or Securities or any other amounts under any other provision of the Indenture, or which shall have been made out of any insurance moneys or moneys received from the condemnation, sale or other disposition of any of the Company's property subject to the Lien of the Indenture, or which shall have previously been used or applied or certified to the Trustee to comply with this Article Four or any other provision of the Indenture and (ii) no retirement of Securities which shall have been made with moneys applied to such purpose pursuant to any provision of this Article Four or of Section 4.04 or 8.06 of the Original Indenture, shall be certified or used or applied for the purpose of complying with this Article or

withdrawing any moneys paid to the Trustee pursuant to this Article Four. This Article Four shall not require the annual retirement by the Company of any specific amount of Outstanding Securities.

(d) So long as any of the Series C Bonds are Outstanding, on or before the first day of February of each year beginning February 1, 2007, the Company shall deliver to the Trustee an Officer's Certificate showing in reasonable detail:
(1) the Company's expenditures pursuant to each of subclauses (a)(i), (a)(ii) and (a)(iii) above, or otherwise deposited with the Trustee pursuant to this Article Four; (2) any eligible credit for excess expenditures from prior periods and the extent to which the Company elects to have such excess applied to the period next preceding delivery of such Officer's Certificate; and (3) the amount of cash the Company is depositing with the Trustee concurrently with the delivery of such Officer's Certificate to comply with the requirements of this Article Four. Such Officer's Certificate shall also state that it complies with the requirements of this Article Four.

(e) At the option of the Company, any moneys paid to and held by the Trustee under the provisions of subclause (b) of this Section shall, upon the written request of the Company pursuant to an Officer's Certificate, (1) be applied by the Trustee to the purchase in the open market of Securities of any series, at not exceeding the then applicable Redemption Price, if any, at which Securities of said series may then be redeemed or (2) be paid to or upon the order of the Company to the extent of (i) the principal amount of Securities of said series purchased or paid by the Company and delivered to the Trustee, cancelled or for cancellation and (ii) the accrued interest and the premium, if any, theretofore paid to the Trustee, as hereinabove provided, on such principal amount of Securities. The Company hereby covenants and agrees that it will pay to the Trustee from time to time in cash such additional sums, if any, as shall be paid or required to be paid by the Trustee as or for accrued interest and premium, if any, in respect of any Securities purchased or redeemed pursuant to the provisions of this Section.

(f) Any and all Securities, the retirement (through payment or purchase) of which shall be certified to the Trustee in compliance with the provisions of this Article Four, shall be delivered to the Trustee at or before the time the same shall be so certified and shall thereupon be cancelled and destroyed by the Trustee, unless theretofore cancelled and destroyed. All other Securities received by the Trustee pursuant to any provision of this Article Four shall thereupon be cancelled and destroyed by the Trustee.

ARTICLE FIVE

REPORTS

In addition to the reports the Company must provide pursuant to the Original Indenture, the Company hereby covenants and agrees that:
