Notwithstanding the foregoing, the Company, without notice to or the consent of the Holders of the Notes, by Board Resolutions or indentures supplemental to the Base Indenture from time to time may increase the principal amount of the Notes by issuing Additional Notes in the future on the same terms and conditions as the Initial Notes except for any difference in the issue price and interest accrued prior to the issue date of the Additional Notes, and with the same CUSIP number as the Initial Notes so long as such Additional Notes are fungible for U.S. income tax purposes with the Initial Notes (as determined by the Company). Except as provided in this Section 3.4, any such Board Resolutions or indentures supplemental to the Base Indenture and Sections 2.1 and 3.1 of the Base Indenture, the Company shall not execute and the Trustee shall not authenticate or deliver Notes in excess of the Initial Original Principal Amount.

Interest will be computed on the basis of a 360-day year composed of twelve 30-day months.

If any Interest Payment Date, Maturity Date or Redemption Date falls on a day that is not a Business Day, the required payment shall be made on the next Business Day as if it were made on the date such payment was due and no interest shall accrue on the amount so payable for the period from and after such Interest Payment Date, Maturity Date or Redemption Date, as the case may be.

The Notes will mature on April 15, 2049 (the “Maturity Date”).

Section 3.6. Method of Payment.

Interest shall be payable at the office of the Company maintained by the Company for such purposes, which shall initially be an office or agency of the Trustee. The Company shall pay interest (i) on any Notes in certificated form by check mailed to the address of the person entitled thereto as it appears in the register; provided, however, that a Holder of any Notes in certificated form in the aggregate principal amount of more than $2.0 million may specify by written notice to the Company that it pay interest by wire transfer of immediately available funds to the account specified by the Holder in such notice, or (ii) on any Global Note by wire transfer of immediately available funds to the account of the Depository or its nominee. Any interest on any Note which is payable, but is not punctually paid or duly provided for, on any April 15 or October 15 (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder registered as such on the relevant Record Date, and such Defaulted Interest shall be paid by the Company, at its election in each case, as provided in clause (a) or (b) below:

(a) The Company may elect to make payment of any Defaulted Interest to the persons in whose names the Notes are registered at 5:00 p.m., New York City time, on a special record date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Note and the date of the proposed payment (which shall be not less than twenty-five (25) calendar days after the receipt by the Trustee of such notice), and at the same time the Company shall deposit with the Trustee an amount of monies equal to the aggregate amount to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such monies when deposited to be held in trust for the benefit of the persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Company shall fix a special record date for the payment of such Defaulted Interest which shall be not more than fifteen (15) calendar days and not less than ten (10) calendar days prior to the date of the proposed payment, and not less than ten (10) calendar days after the receipt by the Trustee of the notice of the proposed payment. The Company shall promptly notify the Trustee of such special record date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the special record date therefor to be delivered to each Holder at its address as it appears in the register, not less than ten (10) calendar days prior to such special record date. Notice of the proposed payment of such Defaulted Interest and the special record date therefor having been so mailed, such Defaulted Interest shall be paid to the persons in whose names the Notes are registered at 5:00 p.m., New York City time, on such special record date and shall no longer be payable pursuant to the following clause (b) of this Section 3.6.

(b) The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, and upon such notice as may be required by such exchange or automated quotation system, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

Section 3.11. Registered Securities; Global Form. The Notes will be issued in the form of one or more fully-registered Global Notes in book-entry form, which will be deposited with, or on behalf of, the Depository. The Notes shall not be issuable in Definitive Notes except as provided in Section 3.12 of this Sixth Supplemental Indenture. The Notes and the Trustee’s certificate of authentication shall be substantially in the form attached as Exhibit A hereto. The Company shall execute each Global Note and each Definitive Note, if any. The Trustee shall, in accordance with Section 3.3 of the Base Indenture, authenticate and hold each Global Note as custodian for the Depository, and authenticate each Definitive Note, if any. Each Global Note will represent such of the outstanding Notes as will be specified therein and each shall provide that it represents the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby will be made by the Trustee or a custodian at the direction of the Trustee. The terms and provisions contained in the form of Note attached as Exhibit A hereto shall constitute, and are hereby expressly made, a part of the Indenture and, to the extent applicable, the Company and the Trustee, by their execution and delivery of this Sixth Supplemental Indenture, expressly agree to such terms and provisions and to be bound thereby.

Section 3.12. Transfer and Exchange.

(a) Transfer and Exchange of Global Notes. A Global Note may not be transferred except as a whole by the Depository to a nominee of the Depository, by a nominee of the Depository to the Depository or to another nominee of the Depository, or by the Depository or any such nominee to a successor Depository or a nominee of such successor Depository. All Global Notes will be exchanged by the Company for Definitive Notes if:

(i) the Company delivers to the Trustee notice from the Depository that it is unwilling or unable to continue to act as Depository or that it is no longer a clearing agency registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and, in either case, a successor Depository is not appointed by the Company within ninety (90) days after the date of such notice from the Depository; or

(ii) the Company in its sole discretion determines that the Global Notes (in whole but not in part) should be exchanged for Definitive Notes and delivers a written notice to such effect to the Trustee.

Upon the occurrence of either of the preceding events in (i) or (ii) above, Definitive Notes shall be issued in such names as the Depository shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 3.4 and 3.6 of the Base Indenture. Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 3.12 or Sections 3.4 and 3.6 of the Base Indenture, shall be authenticated and delivered in the form of, and shall be, a Global Note. A Global Note may not be exchanged for another Note other than as provided in this Section 3.12(a), however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 3.12(c) or (d) hereof.

(b) Legend. Any Global Note issued under this Sixth Supplemental Indenture shall bear a legend in substantially the following form:

“THIS GLOBAL NOTE IS HELD BY THE DEPOSITORY (AS DEFINED IN THE BASE INDENTURE GOVERNING THIS NOTE) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (I) THE TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO SECTION 3.12 OF THE SIXTH SUPPLEMENTAL INDENTURE, (II) THIS GLOBAL NOTE MAY BE EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 3.12 OF THE SIXTH SUPPLEMENTAL INDENTURE, (III) THIS GLOBAL NOTE MAY BE DELIVERED TO THE TRUSTEE FOR CANCELLATION PURSUANT TO SECTION 3.9 OF THE BASE INDENTURE AND (IV) THIS GLOBAL NOTE MAY BE TRANSFERRED TO A SUCCESSOR DEPOSITORY WITH THE PRIOR WRITTEN CONSENT OF THE COMPANY.

UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR NOTES IN DEFINITIVE FORM, THIS NOTE MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITORY TO A NOMINEE OF THE DEPOSITORY OR BY A NOMINEE OF THE DEPOSITORY TO THE DEPOSITORY OR ANOTHER NOMINEE OF THE DEPOSITORY OR BY THE DEPOSITORY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITORY OR A NOMINEE OF SUCH SUCCESSOR DEPOSITORY. UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (55 WATER STREET, NEW YORK, NEW YORK) (“DTC”) 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 SUCH OTHER NAME AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR SUCH OTHER ENTITY AS MAY BE

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.”

(c) Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in the Global Notes will be effected through the Depository, in accordance with the provisions of the Indenture and the Applicable Procedures. Transfers of beneficial interests in the Global Notes will require compliance with either subparagraph (i) or (ii) below, as applicable:

(i) Transfer of Beneficial Interests in the Same Global Note. Beneficial interests in any Global Note may be transferred to persons who take delivery thereof in the form of a beneficial interest in a Global Note. No written orders or instructions shall be required to be delivered to the Security Registrar to effect the transfers described in this Section 3.12(c)(i).

(ii) All Other Transfers of Beneficial Interests in Global Notes. In connection with all transfers of beneficial interests that are not subject to Section 3.12(c)(i) above, the transferor of such beneficial interest must deliver to the Security Registrar both:

(A) a written order from a Participant or an Indirect Participant given to the Depository in accordance with the Applicable Procedures directing the Depository to credit or cause to be credited a beneficial interest in another Global Note in an amount equal to the beneficial interest to be transferred or exchanged; and

(B) instructions given in accordance with the Applicable Procedures containing information regarding the Participant account to be credited with such increase.

Upon satisfaction of all of the requirements for transfer or exchange of beneficial interests in Global Notes contained in the Indenture and the Notes or otherwise applicable under the Securities Act, the Trustee shall adjust the principal amount of the relevant Global Note(s) pursuant to Section 3.12(g) hereof.

(d) Transfer and Exchange of Beneficial Interests in Global Notes for Definitive Notes. If any holder of a beneficial interest in a Global Note proposes to exchange such beneficial interest for a Definitive Note or to transfer such beneficial interest to a person who takes delivery thereof in the form of a Definitive Note, then, upon satisfaction of the conditions set forth in Section 3.12(c)(ii) hereof and receipt of a Company Order, the Trustee will cause the aggregate principal amount of the applicable Global Note to be reduced accordingly pursuant to Section 3.12(g) hereof, and the Company will execute and the Trustee will authenticate and deliver to the person designated in the instructions a Definitive Note in the appropriate principal amount. Any Definitive Note issued in exchange for a beneficial interest pursuant to this Section 3.12(d) will be registered in such name or names and in such authorized denomination or denominations as the holder of such beneficial interest requests through

instructions to the Security Registrar from or through the Depository and the Participant or Indirect Participant. The Trustee will deliver such Definitive Notes to the persons in whose names such Notes are so registered.

(e) Transfer and Exchange of Definitive Notes for Beneficial Interests in Global Notes. A Holder of a Definitive Note may exchange such Note for a beneficial interest in a Global Note or transfer such Definitive Notes to a person who takes delivery thereof in the form of a beneficial interest in a Global Note at any time. Upon receipt of a written request for such an exchange or transfer, the Trustee will cancel the applicable Definitive Note and increase or cause to be increased the aggregate principal amount of one of the Global Notes.

If any such exchange or transfer from a Definitive Note to a beneficial interest is effected pursuant to the previous paragraph at a time when a Global Note has not yet been issued, the Company will issue and, upon receipt of a Company Order in accordance with Section 3.12 hereof, the Trustee will authenticate one or more Global Notes in an aggregate principal amount equal to the principal amount of Definitive Notes so transferred.

(f) Transfer and Exchange of Definitive Notes for Definitive Notes. Upon request by a Holder of Definitive Notes and such Holder’s compliance with the provisions of this Section 3.12(f), the Security Registrar will register the transfer or exchange of Definitive Notes. Prior to such registration of transfer or exchange, the requesting Holder will present or surrender to the Security Registrar the Definitive Notes duly endorsed or accompanied by a written instruction of transfer in form satisfactory to the Security Registrar duly executed by such Holder or by his attorney, duly authorized in writing. A Holder of Definitive Notes may transfer such Notes to a person who takes delivery thereof in the form of a Definitive Note. Upon receipt of a written request to register such a transfer, the Security Registrar shall register the Definitive Notes pursuant to the instructions from the Holder thereof.

(g) Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note will be returned to or retained and canceled by the Trustee in accordance with Section 3.9 of the Base Indenture. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note will be reduced accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depository at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note will be increased accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depository at the direction of the Trustee to reflect such increase.

Section 3.13. General Provisions Relating to Transfers and Exchanges.

(a) To permit registrations of transfers and exchanges, the Company will execute and the Trustee will authenticate Global Notes and Definitive Notes upon receipt of a Company Order in accordance with Section 3.12 hereof.

(b) No service charge will be made to a Holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 3.4 and 9.6 of the Base Indenture).

(c) The Security Registrar will not be required to register the transfer of or exchange of any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part.

(d) All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes will be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under the Indenture, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange.

(e) Neither the Security Registrar nor the Company will be required:

(i) to issue or register the transfer or exchange of any Note during a period beginning at the opening of business fifteen (15) days before any selection of Notes for redemption under Article IV hereof and ending at the close of business on the earliest date on which the relevant notice of redemption is deemed to have been given to all Holders of Notes to be so redeemed; or

(ii) to register the transfer of or to exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part; or

(g) The Trustee will authenticate Global Notes and Definitive Notes in accordance with the provisions of Section 3.3 of the Base Indenture.

ARTICLE IV

REDEMPTION

The provisions of Article XI of the Base Indenture, as amended by the provisions of this Sixth Supplemental Indenture, shall apply to the Notes.

Section 4.1. Optional Redemption.

(a) At any time before October 15, 2048, the Company shall have the right to redeem the Notes at its option and in its sole discretion, in whole or from time to time in part. The redemption price (“Redemption Price”) shall be equal to the sum of (1) the principal amount of the Notes being redeemed, (2) accrued and unpaid interest thereon to, but excluding, the Redemption Date, and (3) the Make-Whole Amount, if any (subject to the right of holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date). Notwithstanding the foregoing, the Redemption Price for any redemption of the Notes on or after October 15, 2048 shall be equal to the sum of (1) the principal amount of the Notes being redeemed and (2) accrued and unpaid interest thereon to, but excluding, the Redemption Date.

(b) The Company shall not redeem the Notes pursuant to Section 4.1(a) hereof on any date if the principal amount of the Notes has been accelerated, and such an acceleration has not been rescinded or cured on or prior to such date (except in the case of an acceleration resulting from a default by the Company in the payment of the Redemption Price with respect to the Notes to be redeemed).

Section 4.2. Notice of Optional Redemption; Selection of Notes. In case the Company shall desire to exercise the right to redeem all or, as the case may be, any part of the Notes pursuant to Section 4.1 hereof, it shall fix a date for redemption and it or, at its written request received by the Trustee not fewer than five (5) Business Days prior (or such shorter period of time as may be acceptable to the Trustee) to the date the notice of redemption is to be delivered, the Trustee in the name of and at the expense of the Company, shall deliver or cause to be delivered a notice of such redemption not fewer than thirty (30) calendar days nor more than sixty (60) calendar days prior to the Redemption Date to each Holder of Notes so to be redeemed in whole or in part at its last address as the same appears on the register; provided that if the Company makes such request of the Trustee, it shall, together with such request, also give written notice of the Redemption Date to the Trustee; provided further that the text of the notice shall be prepared by the Company. The notice, if delivered in the manner herein provided, shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. In any case, failure to give such notice or any defect in the notice to the Holder of any Note designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Note. Any such notice of redemption may, in the Company’s sole discretion, be conditioned on the occurrence of one or more events, facts and circumstances.

Each such notice of redemption shall specify: (i) the aggregate principal amount of Notes to be redeemed, (ii) the CUSIP number or numbers, if any, of the Notes being redeemed, (iii) the Redemption Date (which shall be a Business Day), (iv) the Redemption Price at which Notes are to be redeemed, (v) the place or places of payment and that payment will be made upon presentation and surrender of such Notes and (vi) that interest accrued and unpaid to, but excluding, the Redemption Date will be paid as specified in said notice, and that, unless the Company defaults in the payment of the Redemption Price, on and after said date interest thereon or on the portion thereof to be redeemed will cease to accrue. If fewer than all the Notes are to be redeemed, the notice of redemption shall identify the Notes to be redeemed (including CUSIP numbers, if any). In case any Note is to be redeemed in part only, the notice of redemption shall state the portion of the principal amount thereof to be redeemed and shall state that, on and after the Redemption Date, upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion thereof will be issued.

Whenever any Notes are to be redeemed, the Company will give the Trustee written notice of the Redemption Date as to the aggregate principal amount of Notes to be redeemed not fewer than thirty (30) calendar days prior to the Redemption Date.

On or prior to the Redemption Date specified in the notice of redemption given as provided in this Section 4.2, the Company will deposit with the Paying Agent an amount of monies in immediately available funds sufficient to redeem on the Redemption Date all the Notes (or portions thereof) so called for redemption at the appropriate Redemption Price; provided that if such payment is made on the Redemption Date, it must be received by the Paying Agent, by 11:00 a.m., New York City time, on such date.

If less than all of the outstanding Notes are to be redeemed, the Trustee shall select the Notes or portions thereof of the Global Note or the Notes in certificated form to be redeemed (in principal amounts of $2,000 and integral multiples of $1,000 in excess thereof), on a pro rata basis or such other method the Trustee deems fair and appropriate or is required by the Depository. The Notes (or portions thereof) so selected for redemption shall be deemed duly selected for redemption for all purposes hereof.

Section 4.3. Payment of Notes Called for Redemption by the Company. If notice of redemption has been given as provided in Section 4.2 hereof, the Notes or portion of Notes with respect to which such notice has been given shall become due and payable on the Redemption Date and at the place or places stated in such notice at the Redemption Price, and unless the Company shall default in the payment of such Notes at the Redemption Price, so long as the Paying Agent holds funds sufficient to pay the Redemption Price of the Notes to be redeemed on the Redemption Date, then (a) such Notes will cease to be outstanding on and after the Redemption Date, (b) interest on the Notes or portion of Notes so called for redemption shall cease to accrue on and after the Redemption Date, (c) on and after the Redemption Date (unless the Company shall default in the payment of the Redemption Price), such Notes will cease to be entitled to any benefit or security under this Indenture, and (d) the Holders of the Notes shall have no right in respect of such Notes except the right to receive the Redemption Price thereof. On presentation and surrender of such Notes at a place of payment in said notice specified, the said Notes or the specified portions thereof shall be paid and redeemed by the Company at the Redemption Price.

Upon presentation of any Note redeemed in part only, the Company shall execute and the Trustee shall authenticate and make available for delivery to the Holder thereof, at the expense of the Company, a new Note or Notes, of authorized denominations, in principal amount equal to the unredeemed portion of the Notes so presented.

ARTICLE V

GUARANTEE

This Article V shall replace Article XIV of the Base Indenture with respect to the Notes only.

Section 5.1. Guarantee. By its execution hereof, the Guarantor acknowledges and agrees that the Notes shall be entitled to the benefits of a Guarantee. Accordingly, subject to the provisions of this Article V, the Guarantor hereby unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee or its successor or assign, and to the Trustee and its successors and assigns that: (i) the principal of (including the Redemption Price upon redemption pursuant to Article IV hereof), premium, if any, and interest, if any, on the Notes shall be duly and punctually paid in full when due, whether at the Maturity Date, upon acceleration, upon redemption or otherwise, and interest on overdue principal, premium, if any, and (to the extent permitted by law) interest on any interest, if any, on the Notes and all other obligations of the Company to the Holders or the Trustee hereunder or under the Notes (including fees, expenses or other) shall be promptly paid in full or performed, all in accordance with the terms hereof; and (ii) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, the same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at the Maturity Date, by acceleration, call for redemption or otherwise, subject, however, in the case of clauses (i) and (ii) above, to the limitations set forth in this Article V (collectively, the “Guarantee Obligations”).

Subject to the provisions of this Article V, the Guarantor hereby agrees that its Guarantee hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any thereof, the entry of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of the Guarantor. The Guarantor hereby waives and relinquishes: (a) any right to require the Trustee, the Holders or the Company (each, a “Benefited Party”) to proceed against the Company or any other person or to proceed against or exhaust any security held by a Benefited Party at any time or to pursue any other remedy in any secured party’s power before proceeding against the Guarantor; (b) any defense that may arise by reason of the incapacity, lack of authority, death or disability of any other person or persons or the failure of a Benefited Party to file or enforce a claim against the estate (in administration, bankruptcy or any other proceeding) of any other person or persons; (c) demand, protest and notice of any kind (except as expressly required by the Indenture), including but not limited to notice of the existence, creation or incurring of any new or additional indebtedness or obligation or of any action or non-action on the part of the Guarantor, any Benefited Party, any creditor of the Guarantor or the Company or on the part of any other person whomsoever in

connection with any obligations the performance of which are hereby guaranteed; (d) any defense based upon an election of remedies by a Benefited Party, including but not limited to an election to proceed against the Guarantor for reimbursement; (e) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal; (f) any defense arising because of a Benefited Party’s election, in any proceeding instituted under the Bankruptcy Law, of the application of Section 1111(b)(2) of the Bankruptcy Law; and (g) any defense based on any borrowing or grant of a security interest under Section 364 of the Bankruptcy Law. The Guarantor hereby covenants that, except as otherwise provided therein, the Guarantee shall not be discharged except by payment in full of all Guarantee Obligations, including, but not limited to, the principal, premium, if any, and interest on the Notes and all other costs provided for under the Indenture.

If any Holder or the Trustee is required by any court or otherwise to return to either the Company or the Guarantor, or any trustee or similar official acting in relation to either the Company or the Guarantor, any amount paid by the Company or the Guarantor to the Trustee or such Holder, the Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. The Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any Guarantee Obligations hereby until payment in full of all such obligations guaranteed hereby. The Guarantor agrees that, as between it, on the one hand, and the Holders of Notes and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article V of the Base Indenture for the purposes hereof, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guarantee Obligations, and (y) in the event of any acceleration of such obligations as provided in Article V of the Base Indenture, such Guarantee Obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantor for the purpose of the Guarantee.

Section 5.2. Execution and Delivery of Guarantee.

(a) To evidence the Guarantee set forth in Section 5.1 hereof, the Guarantor agrees that a Notation of Guarantee substantially in the form included in Exhibit B hereto shall be endorsed on each Note authenticated and delivered by the Trustee and that this Sixth Supplemental Indenture shall be executed on behalf of the Guarantor by an Officer of the sole general partner of the Guarantor.

(b) The Guarantor agrees that the Guarantee set forth in this Article V shall remain in full force and effect and apply to all the Notes notwithstanding any failure to endorse on each Note a notation of the Guarantee.

(c) If an Officer whose facsimile signature is on a Note or a notation of Guarantee no longer holds that office at the time the Trustee authenticates the Note on which the Guarantee is endorsed, the Guarantee shall be valid nevertheless.

(d) The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Guarantee set forth in this Sixth Supplemental Indenture on behalf of the Guarantor.

Section 5.3. Limitation of Guarantor’s Liability; Certain Bankruptcy Events.

(a) The Guarantor, and by its acceptance hereof each Holder, hereby confirms that it is the intention of all such parties that the Guarantee Obligations of the Guarantor pursuant to its Guarantee not constitute a fraudulent transfer or conveyance for purposes of any Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law. To effectuate the foregoing intention, the Holders and the Guarantor hereby irrevocably agree that the Guarantee Obligations of the Guarantor under this Article V shall be limited to the maximum amount as shall, after giving effect to all other contingent and fixed liabilities of the Guarantor, result in the Guarantee Obligations of the Guarantor under the Guarantee not constituting a fraudulent transfer or conveyance.

(b) The Guarantor hereby covenants and agrees, to the fullest extent that it may do so under applicable law, that in the event of the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Company, the Guarantor shall not file (or join in any filing of), or otherwise seek to participate in the filing of, any motion or request seeking to stay or to prohibit (even temporarily) execution on the Guarantee and hereby waives and agrees not to take the benefit of any such stay of execution, whether under Section 362 or 105 of the Bankruptcy Law or otherwise.

Section 5.4. Application of Certain Terms and Provisions to the Guarantor.

(a) For purposes of any provision of the Indenture which provides for the delivery by the Guarantor of an Officers’ Certificate and/or an Opinion of Counsel, the definitions of such terms in Section 2.1 hereof shall apply to the Guarantor as if references therein to the Company or the Guarantor, as applicable, were references to the Guarantor; provided that, in the case of any Officers’ Certificate delivered by the Guarantor, the definition of the term “Officer” shall be deemed to include the general partner of the Guarantor.

(b) Upon any demand, request or application by the Guarantor to the Trustee to take any action under the Indenture, the Guarantor shall furnish to the Trustee such certificates and opinions as are required in Section 1.2 of the Base Indenture, as if all references therein to the Company were references to the Guarantor.

ARTICLE VI

ADDITIONAL COVENANTS

The following additional covenants shall apply with respect to the Notes so long as any of the Notes remain outstanding.

Section 6.1. Maintenance of Office or Agency. The Company will maintain an office or agency in the United States where the Notes may be surrendered for registration of transfer or exchange or for presentation for payment or redemption and where notices and demands to or upon the Company in respect of the Notes and the Indenture may be served. As of the date of the Indenture, such office shall be the Corporate Trust Office and, at any other time, at such other

address as the Trustee may designate from time to time by notice to the Company. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency not designated or appointed by the Trustee. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office; provided that the Corporate Trust Office shall not be an office for service of legal process on the Company or any Guarantor.

The Company may also from time to time designate co-registrars and one or more offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

The Company hereby initially designates the Trustee as Paying Agent and Security Registrar and the Corporate Trust Office shall be considered as one such office or agency of the Company for each of the aforesaid purposes.

Section 6.2. Appointments to Fill Vacancies in Trustee’s Office. The Company, whenever necessary to avoid or fill a vacancy in the office of Trustee, will appoint, upon the terms and conditions and otherwise as provided in Section 6.11 of the Base Indenture, a Trustee, so that there shall at all times be a Trustee hereunder.

Section 6.3. Limitations on Incurrence of Debt.

(a) The Company will not, and will not permit any of its Subsidiaries to, incur any Debt, other than Intercompany Debt and guarantees of Debt incurred by the Company or its Subsidiaries in compliance with this Indenture, if, immediately after giving effect to the incurrence of such Debt and the application of the proceeds thereof, the aggregate principal amount of all of the Company’s and its Subsidiaries’ outstanding Debt on a consolidated basis determined in accordance with GAAP is greater than 60% of the sum of (without duplication) (1) Total Assets as of the end of the calendar quarter covered in the Company’s Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as the case may be, most recently filed with the Commission (or, if such filing is not permitted under the Exchange Act, with the Trustee) prior to the incurrence of such additional Debt and (2) the purchase price of any real estate assets or mortgages receivable acquired, and the amount of any securities offering proceeds received (to the extent such proceeds were not used to acquire real estate assets or mortgages receivable or used to reduce Debt), by the Company or any of its Subsidiaries since the end of such calendar quarter, including those proceeds obtained in connection with the incurrence of such additional Debt.

(b) The Company will not, and will not permit any of its Subsidiaries to, incur any Debt, other than Intercompany Debt and guarantees of Debt incurred by the Company or its Subsidiaries in compliance with this Indenture, secured by any mortgage, lien, charge, pledge, encumbrance or security interest of any kind upon any of the Company’s or any of its Subsidiaries’ property if, immediately after giving effect to the incurrence of such Debt and the application of the proceeds thereof, the aggregate principal amount of all of the Company’s and

its Subsidiaries’ outstanding Debt on a consolidated basis which is secured by any mortgage, lien, charge, pledge, encumbrance or security interest on the Company’s or its Subsidiaries’ property is greater than 40% of the sum of (without duplication) (1) Total Assets as of the end of the calendar quarter covered in the Company’s Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as the case may be, most recently filed with the Commission (or, if such filing is not permitted under the Exchange Act, with the Trustee) prior to the incurrence of such additional Debt and (2) the purchase price of any real estate assets or mortgages receivable acquired, and the amount of any securities offering proceeds received (to the extent such proceeds were not used to acquire real estate assets or mortgages receivable or used to reduce Debt), by the Company or any of its Subsidiaries since the end of such calendar quarter, including those proceeds obtained in connection with the incurrence of such additional Debt; provided that for purposes of this limitation, the amount of obligations under capital leases shown as a liability on the Company’s consolidated balance sheet shall be deducted from Debt and from Total Assets.

(c) The Company will not, and will not permit any of its Subsidiaries to, incur any Debt, other than Intercompany Debt and guarantees of Debt by the Company or its Subsidiaries in compliance with this Indenture, if the ratio of Consolidated EBITDA to Interest Expense for the four consecutive fiscal quarters most recently ended prior to the date on which such additional Debt is to be incurred shall have been less than 1.5 to 1.0, on an unaudited pro forma basis after giving effect to the incurrence of such additional Debt and to the application of the proceeds therefrom, and calculated on the assumption that: (1) such Debt and any other Debt incurred by the Company and its Subsidiaries since the first day of such four-quarter period and the application of the proceeds therefrom, including to refinance other Debt, had occurred at the beginning of such period (except that, in making such computation, the amount of Debt under any revolving credit facility shall be computed based on the average daily balance of such Debt during such period); (2) the repayment or retirement of any other Debt by the Company and its Subsidiaries since the first day of such four-quarter period had been repaid or retired at the beginning of such period (except that, in making such computation, the amount of Debt under any revolving credit facility shall be computed based upon the average daily balance of such Debt during such period); (3) in the case of Acquired Debt or Debt incurred in connection with any acquisition since the first day of such four-quarter period, the related acquisition had occurred as of the first day of such period, with the appropriate adjustments with respect to such acquisition being included in such unaudited pro forma calculation; and (4) in the case of any acquisition or disposition by the Company or its Subsidiaries of any asset or group of assets or other placement of any assets in service or removal of any assets from service by the Company or any of its Subsidiaries since the first day of such four-quarter period, whether by merger, stock purchase or sale, or asset purchase or sale, such acquisition, disposition, placement in service or removal from service, or any related repayment of Debt had occurred as of the first day of such period, with the appropriate adjustments with respect to such acquisition, disposition, placement in service or removal from service, being included in such unaudited pro forma calculation and determined reasonably and in good faith by the Company. If the Debt giving rise to the need to make the foregoing calculation or any other Debt incurred after the first day of the relevant four-quarter period bears interest at a floating rate then, for purposes of calculating the Interest Expense, the interest rate on such Debt shall be computed on a pro forma basis as if the average interest rate which would have been in effect during the entire such four-quarter period had been the applicable rate for the entire such period.

(d) The Company, together with its Subsidiaries, will at all times maintain an Unencumbered Total Asset Value in an amount not less than 150% of the aggregate outstanding principal amount of all the Company’s and its Subsidiaries’ unsecured Debt, taken as a whole.

(e) The Company will, and will cause each of its Subsidiaries to, maintain insurance with financially sound and reputable insurance companies against such risks and in such amounts as is customarily maintained by persons engaged in similar businesses or as may be required by applicable law.

Section 6.4. Provision of Financial Reporting Information. For so long as the Notes are outstanding, if at any time the Company is not subject to the periodic reporting requirements of the Exchange Act for any reason, the Company shall, at its option, (i) post on a publicly available website, (ii) post on IntraLinks or any comparable password protected online data system requiring user identification and a confidentiality acknowledgement (any such data system, a “Confidential Datasite”), or (iii) deliver to the Trustee and the Holders of the Notes, in each case within 15 days of the filing date that would be applicable to a non-accelerated filer at that time pursuant to applicable SEC rules and regulations, the quarterly and audited annual financial statements and accompanying “Management’s Discussion and Analysis of Financial Condition and Results of Operations” that would have been required to be contained in annual reports on Form 10-K and quarterly reports on Form 10-Q, respectively, had the Company been subject to such Exchange Act reporting requirements. The Trustee shall have no obligation to determine whether or not such reports, information, statements or documents have been filed, posted or delivered. Delivery of such reports, information, statements and documents to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants under the Indenture. If the Company elects to furnish such reports via a Confidential Datasite, access to the Confidential Datasite will be provided upon request to the Holders and the beneficial owners of and bona fide potential investors in the Notes.

Section 7.2. Acceleration of Maturity; Rescission and Annulment. If an Event of Default with respect to the Notes at the time outstanding occurs and is continuing (other than an Event of Default referred to in Section 7.1 (f), (g) or (h) hereof), then in every such case the Trustee or the Holders of not less than 25% in principal amount of the outstanding Notes may, by a notice in writing to the Company (and to the Trustee if given by the Holders), declare to be due and payable immediately the principal of, and accrued and unpaid interest, if any, on all of the Notes, and upon any such declaration such principal amount (or specified amount) and accrued and unpaid interest, if any, shall become immediately due and payable. If an Event of Default specified in Section 7.1 (f), (g) or (h) hereof shall occur, the principal amount (or specified amount) of and accrued and unpaid interest, if any, on all outstanding Notes will automatically become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder of outstanding Notes.

At any time after a declaration of acceleration with respect to Notes has been made, but before a judgment or decree for payment of the money due has been obtained by the Trustee, the Holders of a majority in principal amount of the outstanding Notes, by written notice to the Company and the Trustee, may rescind and annul such declaration and the acceleration if all Events of Default, other than the non-payment of accelerated principal and interest, if any, with respect to the Notes, have been cured or waived as provided in Section 5.13 of the Base Indenture. No such rescission and annulment shall extend to or shall affect any subsequent default or Event of Default, or shall impair any right consequent thereon.

Section 7.3. Limitation on Suits. No Holder of the Notes shall have any right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee, or for any remedy under the Indenture, unless:

(a) such Holder has previously given to the Trustee written notice of a continuing Event of Default with respect to the Notes;

(b) the Holders of at least 25% in principal amount of the outstanding Notes shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder,

(c) such Holder or Holders have offered to the Trustee indemnity reasonably satisfactory to it against the costs, expenses and liabilities to be incurred in compliance with such request;

(d) the Trustee for sixty (60) days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and

(e) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of at least 25% in principal amount of the outstanding Notes.

Section 7.4. Notice of Defaults. If an Event of Default occurs and is continuing with respect to the Notes and if it is actually known to a Responsible Officer of the Trustee, the Trustee will send to Holders of Notes a notice of the Default or Event of Default within 90 days after it occurs, unless such default shall have been cured or waived. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, or interest on the Notes, the Trustee may withhold the notice if and so long as a Responsible Officer determines that withholding the notice is in the interests of the Holders of the Notes.

ARTICLE VIII

AMENDMENTS AND WAIVERS

Section 8.1 hereof shall replace Section 9.1 of the Base Indenture with respect to the Notes only.

Section 8.1. Without Consent of Holders. The Company, when authorized by the resolutions of the Board of Directors, the Guarantor and the Trustee may, from time to time, and at any time enter into an indenture or indentures supplemental without the consent of the Holders of the Notes hereto for one or more of the following purposes:

Upon the written request of the Company, accompanied by a copy of the resolutions of each of the Board of Directors of the Company and the Board of Directors of the sole general partner of the Guarantor authorizing the execution of any supplemental indenture and the delivery of the documents required by Section 9.3 of the Base Indenture, the Trustee is hereby authorized to join with the Company and the Guarantor in the execution of any such supplemental indenture, to make any further appropriate agreements and stipulations that may be therein contained and to accept the conveyance, transfer and assignment of any property thereunder, but the Trustee shall not be obligated to, but may in its discretion, enter into any supplemental indenture that affects the Trustee’s own rights, duties or immunities under the Indenture or otherwise.

(b) The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the Company or by Holders as provided in Section 9.2(b) hereof, in which case the Company, the Guarantor or the Holders calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting shall be elected by vote of the persons entitled to vote a majority in principal amount of the outstanding Notes of such series represented at the meeting.

(c) At any meeting, each Holder or proxy shall be entitled to one (1) vote for each $1,000 principal amount of Notes held or represented by him; provided, however, that no vote shall be cast or counted at any meeting in respect of any Note challenged as not outstanding and ruled by the chairman of the meeting to be not outstanding. The chairman of the meeting shall have no right to vote, except as a Holder or proxy.

(d) Any meeting of Holders duly called pursuant to Section 9.2 hereof at which a quorum is present may be adjourned from time to time by persons entitled to vote a majority in principal amount of the outstanding Notes represented at the meeting; and the meeting may be held as so adjourned without further notice.

This Note is one of a duly authorized issue of Securities of the Company, designated as its 4.850% Senior Notes due 2049 (herein called the “Notes”), issued under and pursuant to an Indenture dated as of March 3, 2017 (herein called the “Base Indenture”), among the Company, the Guarantor and Branch Banking and Trust Company, as trustee (herein called the “Trustee”), as supplemented by the Supplemental Indenture No. 6, dated as of March 21, 2019 (herein called the “Sixth Supplemental Indenture,” and, together with the Base Indenture, the “Indenture”), to which Indenture and any indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company, the Guarantor and the Holders of the Notes. Capitalized terms used but not otherwise defined in this Note shall have the respective meanings ascribed thereto in the Indenture. In the event of any conflict between the terms of this Note and the terms of the Indenture, the terms of the Indenture control.

If an Event of Default (other than an Event of Default specified in Sections 7.1(f), 7.1(g) and 7.1(h) of the Sixth Supplemental Indenture) occurs and is continuing, the principal of, premium, if any, and accrued and unpaid interest on all Notes may be declared to be due and payable by either the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding, and, upon said declaration the same shall be immediately due and payable. If an Event of Default specified in Sections 7.1(f), 7.1(g) and 7.1(h) of the Sixth Supplemental Indenture occurs, the principal of and premium, if any, and interest accrued and unpaid on all the Notes shall be immediately and automatically due and payable without necessity of further action.

The Indenture contains provisions permitting the Company and the Trustee, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding, to execute supplemental indentures adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or modifying in any manner the rights of the Holders of the Notes, subject to exceptions set forth in Section 9.2 of the Base Indenture. Subject to the provisions of the Indenture, the Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding may, on behalf of the Holders of all of the Notes, waive any past Default or Event of Default, subject to exceptions set forth in the Indenture.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall impair, as among the Company and the Holder of the Notes, the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium, if any, on and interest on this Note at the place, at the respective times, at the rate and in the coin or currency prescribed herein and in the Indenture.

Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months.
