In case any Officer of the General Partner who shall have signed any of the Notes shall cease to be such Officer of the General Partner before the Notes so signed shall have been authenticated and delivered by the Trustee, or disposed of by the Issuer, such Notes nevertheless may be authenticated and delivered or disposed of as though the person who signed such Notes had not ceased to be such Officer of the General Partner, and any Note may be signed on behalf of the Issuer by such persons as, at the actual date of the execution of such Note, shall be the proper Officers of the General Partner, although at the date of the execution of this Supplemental Indenture any such person was not such an Officer of the General Partner.

Section 2.05. Note Registrar and Paying Agent.

The Issuer will maintain an office or agency where Notes may be presented for registration of transfer or for exchange (“Note Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”). The Note Registrar will keep a register of the Notes and of their transfer and exchange (the “Note Register”). The Issuer may appoint one or more co-registrars and one or more additional paying agents. The term “Note Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Issuer may change any Paying Agent or Note Registrar without notice to any Holder. The Issuer will notify the Trustee in writing of the name and address of any Agent not a party to this Supplemental Indenture. If the Issuer fails to appoint or maintain another entity as Note Registrar or Paying Agent, the Trustee shall act as such. The Issuer or any of its Subsidiaries may act as Paying Agent or Note Registrar.

The Issuer initially appoints the DTC to act as Depositary with respect to the Global Notes.

The Issuer initially appoints the Trustee to act as the Note Registrar and Paying Agent and to act as Custodian with respect to the Global Notes.

The Issuer will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium or interest on the Notes, and will notify the Trustee of any default by the Issuer in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Issuer at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Issuer or its Subsidiary) will have no further liability for the money. If the Issuer or a Subsidiary of the Issuer acts as Paying Agent, it will segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Issuer, the Trustee will serve as Paying Agent for the Notes.

Section 2.06. Exchange and Registration of Transfer of Notes; Restrictions on Transfer.

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

(1) the Issuer delivers to the Trustee notice from the Depositary that it is unwilling or unable to continue to act as Depositary or that it has ceased to be a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Issuer within 120 days after the date of such notice from the Depositary;

(2) the Issuer 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; or

(3) upon request from the Depositary if there has occurred and is continuing a Default or Event of Default with respect to the Notes.

13

Upon the occurrence of either of the preceding events in (1) or (2) above, Definitive Notes shall be issued in such names as the Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.07 and 2.08 hereof. Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06 or Sections 2.07 or 2.08 hereof, 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 2.06(a), however, beneficial interests in a Global Note may be transferred and exchanged as provided in Sections 2.06(b) or (f) hereof.

(b) 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 Depositary, in accordance with the provisions of this Supplemental Indenture and the Applicable Procedures. Transfers of beneficial interests in the Global Notes will require compliance with either subparagraph (1) or (2) below, as applicable, as well as one or more of the other following subparagraphs, as applicable:

(1) 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 Note Registrar to effect the transfers described in this Section 2.06(b)(1).

(2) All Other Transfers and Exchanges of Beneficial Interests in Global Notes. In connection with all transfers and exchanges of beneficial interests that are not subject to Section 2.06(b)(1) above, the transferor of such beneficial interest must deliver to the Note Registrar either:

(A) both:

(i) a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary 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

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

(B) both:

(i) a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to cause to be issued a Definitive Note in an amount equal to the beneficial interest to be transferred or exchanged; and

(c) Transfer or Exchange of Beneficial Interests 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 2.06(b)(2) hereof, the Trustee will cause the aggregate principal amount of the applicable Global Note to be reduced accordingly pursuant to Section 2.06(g) hereof, and the Issuer 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 2.06(c) 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 Note Registrar from or through the Depositary and the Participant or Indirect Participant. The Trustee will deliver such Definitive Notes to the Persons in whose names such Notes are so registered.

(d) Transfer and Exchange of Definitive Notes for Beneficial Interests. 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 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.

(e) Transfer and Exchange of Definitive Notes for Definitive Notes. A Holder of Definitive Notes may transfer such Notes to a Person who takes delivery thereof in the form of a Definitive Note. Prior to such registration of transfer or exchange, the requesting Holder must present or surrender to the Note Registrar the Definitive Notes duly endorsed or accompanied by a written instruction of transfer in form satisfactory to the Note Registrar duly executed by such Holder or by its attorney, duly authorized in writing.

OR SUCH OTHER NAME AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO.

(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 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 2.09 hereof. 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 Depositary 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 Depositary at the direction of the Trustee to reflect such increase.

(h) General Provisions Relating to Transfers and Exchanges.

(1) To permit registrations of transfers and exchanges, the Issuer will execute and the Trustee will authenticate Global Notes and Definitive Notes upon receipt of an Authentication Order in accordance with Section 2.04 hereof or at the Note Registrar’s request.

16

(3) The Note 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.

(4) 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 Issuer, evidencing the same debt, and entitled to the same benefits under this Supplemental Indenture, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange.

(5) Neither the Note Registrar nor the Issuer will be required:

(A) to issue, register the transfer of or to exchange any Note during a period beginning at the opening of business fifteen (15) days before the mailing of a notice of redemption of the Notes selected for redemption and ending at the close of business on the day of such mailing; or

All notices and communications to be given to the Noteholders and all payments to be made to Noteholders under the Notes shall be given or made only to or upon the order of the registered Noteholders (which shall be the Depositary or its nominee in the case of a Global Note). The rights of beneficial owners in any Global Note shall be exercised only through the Depositary subject to the customary procedures of the Depositary. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its Participants.

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

Section 2.07. Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become mutilated or be destroyed, lost or stolen, the Issuer in its discretion may execute, and upon its written request the Trustee or an authenticating agent appointed by the Trustee shall authenticate and make available for delivery, a new Note, bearing a number not contemporaneously outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case, the applicant for a substituted Note shall furnish to the Issuer, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Issuer, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

Following receipt by the Trustee or such authenticating agent, as the case may be, of satisfactory security or indemnity and evidence, as described in the preceding paragraph, the Trustee or such authenticating agent may authenticate any such substituted Note and make available for delivery such Note. Upon the issuance of any substituted Note, the Issuer may require the payment by the Holder of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in relation thereto and any other expenses connected therewith. In case any Note which has matured or is about to mature or has been called for redemption, as the case may be, shall become mutilated or be destroyed, lost or stolen, the Issuer may, instead of issuing a substitute Note, pay or authorize the payment of, as the case may be, if the applicant for such payment shall furnish to the Issuer, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or in connection with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Issuer, the Trustee and, if applicable, any Paying Agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

18

Every substitute Note issued pursuant to the provisions of this Section 2.07 by virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Issuer, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set forth in) this Supplemental Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement or payment or exchange or redemption of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment or redemption of negotiable instruments or other securities without their surrender.

Section 2.08. Temporary Notes. Pending the preparation of Notes in certificated form, the Issuer may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon the written request of the Issuer, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any authorized denomination, and substantially in the form of the Notes in certificated form, but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Issuer. Every such temporary Note shall be executed by the Issuer and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Notes in certificated form. Without unreasonable delay, the Issuer will execute and deliver to the Trustee or such authenticating agent Notes in certificated form and thereupon any or all temporary Notes may be surrendered in exchange therefor, at each office or agency maintained by the Issuer pursuant to Section 4.02 hereof and the Trustee or such authenticating agent shall authenticate and make available for delivery in exchange for such temporary Notes an equal aggregate principal amount of Notes in certificated form. Such exchange shall be made by the Issuer at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Supplemental Indenture as Notes in certificated form authenticated and delivered hereunder.

Section 2.09. Cancellation of Notes. All Notes surrendered for the purpose of payment, redemption or registration of transfer shall, if surrendered to the Issuer or any Paying Agent, which shall initially be the Trustee, or any Note Registrar, be surrendered to the Trustee and promptly canceled by it or, if surrendered to the Trustee, shall be promptly canceled by it and no Notes shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Supplemental Indenture. The Trustee shall dispose of such canceled Notes in accordance with its customary procedures, with copies of such cancelled Notes and related documentation provided to the Issuer. If the Issuer shall acquire any of the Notes, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Notes unless and until the same are delivered to the Trustee for cancellation.

19

Section 2.10. CUSIP Numbers. The Issuer in issuing the Notes may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Noteholders; provided, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Issuer will promptly notify the Trustee of any change in the “CUSIP” numbers.

Section 2.11. Issuance of Additional Notes. The Issuer will be entitled, upon delivery of an Officers’ Certificate, Opinion of Counsel and Authentication Order, subject to its compliance with Section 4.09 hereof, to issue Additional Notes under the Indenture that will have identical terms to and the same CUSIP number as any of the Initial Notes issued on the date of this Supplemental Indenture other than with respect to the date of issuance, issue price and interest accrued prior to the issue date of the Additional Notes; provided, that such Additional Notes must be part of the same issue as and fungible with the Initial Notes for United States federal income tax purposes. The Initial Notes and any such Additional Notes will constitute a single series of debt securities, and in circumstances in which this Supplemental Indenture provides for the Holders of Notes to vote or take any action, the Holders of Initial Notes and the Holders of any such Additional Notes will vote or take the action as a single class.

With respect to any Additional Notes, the Issuer will set forth in a resolution of its Board of Directors and an Officers’ Certificate, a copy of each of which will be delivered to the Trustee, the following information:

(1) the aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to this Supplemental Indenture; and

(2) the issue price, the issue date and the CUSIP number of such Additional Notes.

ARTICLE 3

REDEMPTION OF NOTES

Section 3.01. Optional Redemption of Notes.

(a) The Issuer shall have the right to redeem the Notes at its option and in its sole discretion at any time or from time to time prior to the Maturity Date, in whole or in part. Prior to the Par Call Date, the redemption price (“Redemption Price”) will equal the greater of (i) 100% of the principal amount of the Notes to be redeemed or (ii) as determined by the Quotation Agent, 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) that would be due if the Notes matured on the Par Call 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 25 basis points, plus, in each case, accrued and unpaid interest thereon to the Redemption Date; provided, however, that if the Redemption Date falls after a Record Date and on or prior to the corresponding interest payment date, the Issuer will pay the full amount of accrued and unpaid interest, if any, on such interest payment date to

20

the Holder of record at the close of business on the corresponding Record Date (instead of the Holder surrendering its Notes for redemption). If the Notes are redeemed on or after the Par Call Date, the Redemption Price will be equal to 100% of the principal amount of the Notes being redeemed plus unpaid interest, if any, accrued thereon to, but excluding, the Redemption Date.

(b) The Issuer shall not redeem the Notes pursuant to Section 3.01(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 Issuer in the payment of the Redemption Price with respect to the Notes to be redeemed).

Section 3.02. Notice of Optional Redemption; Selection of Notes. In case the Issuer shall desire to exercise the right to redeem all or, as the case may be, any part of the Notes pursuant to Section 3.01 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 mailed (or sent by electronic transmission), the Trustee in the name of and at the expense of the Issuer, shall mail (or send by electronic transmission) or cause to be mailed (or sent by electronic transmission) a notice of such redemption not fewer than fifteen (15) 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 Note Register; provided, that if the Issuer 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 Issuer. Such mailing shall be by first class mail (unless sent by electronic transmission). The notice, if mailed 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 by mail 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.

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 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 Issuer will give the Trustee written notice of the Redemption Date, together with an Officers’ Certificate as to the aggregate principal amount of Notes to be redeemed not fewer than fifteen (15) calendar days (or such shorter period of time as may be acceptable to the Trustee) prior to the Redemption Date.

21

On or prior to the Redemption Date specified in the notice of redemption given as provided in this Section 3.02, the Issuer will deposit with the Paying Agent (or, if the Issuer is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 4.04 hereof) 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. The Issuer shall be entitled to retain any interest, yield or gain on amounts deposited with the Paying Agent pursuant to this Section 3.02 in excess of amounts required hereunder to pay the Redemption Price.

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 Depositary. The Notes (or portions thereof) so selected for redemption shall be deemed duly selected for redemption for all purposes hereof.

Section 3.03. Payment of Notes Called for Redemption by the Issuer. If notice of redemption has been given as provided in Section 3.02 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 Issuer shall default in the payment of such Notes at the Redemption Price, so long as 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) after 5:00 p.m., New York City time, on the second Business Day immediately preceding the Redemption Date (unless the Issuer shall default in the payment of the Redemption Price) and, except as provided in Sections 7.05 and 11.02 hereof, such Notes will cease to be entitled to any benefit or security under this Supplemental 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 Issuer at the Redemption Price, together with interest accrued thereon to, but excluding, the Redemption Date.

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

Section 3.04. Sinking Fund. There shall be no sinking fund provided for the Notes.

As of the date of this Supplemental 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 Issuer. The Issuer 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 Issuer 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, however, that the Corporate Trust Office of the Trustee shall not be an office or agency of the Issuer for the purpose of effective service of legal process on the Issuer.

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

So long as the Trustee is the Note Registrar, the Trustee agrees to mail (or send by electronic transmission), or cause to be mailed, the notices set forth in Section 7.10 and the third paragraph of Section 7.11 hereof. If co-registrars have been appointed in accordance with this Section 4.02, the Trustee shall mail such notices only to the Issuer and the Holders of Notes it can identify from its records.

Section 4.06. Reports.

(a) Whether or not required by the rules and regulations of the Commission, so long as any Notes are outstanding, the Issuer will furnish to the Trustee:

in each case within fifteen (15) days after the Issuer files such reports with the Commission or would be required to file such reports with the Commission pursuant to the applicable rules and regulations of the Commission, whichever is earlier. Reports, information and documents filed with the Commission via the Commission’s Electronic Data Gathering, Analysis and Retrieval system (“EDGAR”) will be deemed to be delivered to the Trustee as of the time of such filing via EDGAR for purposes of this covenant; provided, however, that the Trustee shall have no obligation whatsoever to determine whether or not such information, documents or reports have been filed via EDGAR.

All such reports will be prepared in all material respects in accordance with all of the rules and regulations applicable to such reports. Each annual report on Form 10-K will include a report on the Issuer’s consolidated financial statements by its independent registered public accounting firm, unless otherwise permitted by the Commission.

25

If the Issuer is no longer subject to the periodic reporting requirements of the Exchange Act for any reason, the Issuer will nevertheless continue filing the reports specified in clauses (1) and (2) above with the Commission within the time periods specified above unless the Commission will not accept such a filing. The Issuer will not take any action for the purpose of causing the Commission not to accept any such filings. If, notwithstanding the foregoing, the Commission will not accept the Issuer’s filings for any reason, the Issuer will make the reports referred to in clauses (1) and (2) above available on its website within fifteen (15) days after the Issuer would be required to file such reports with the Commission. Notwithstanding the foregoing, if permitted by the Commission, the Issuer’s obligations to file reports under this Section 4.06(a) may be satisfied by the filing of the reports described in clauses (1) and (2) above by the Guarantor.

(b) For so long as any Notes remain outstanding, if at any time it is not required to file with the Commission the reports required by paragraphs (a) of this Section 4.06, the Issuer will furnish to the Holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

The Issuer covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law which would prohibit or forgive the Issuer from paying all or any portion of the principal, premium, if any, or interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Supplemental Indenture and the Issuer (to the extent it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

Section 4.08. Compliance Certificate. Within one hundred twenty (120) calendar days after the end of each fiscal year of the Issuer, the Issuer and the Guarantor shall deliver to the Trustee a certificate signed by any of the principal executive officer, principal financial officer or principal accounting officer of the Issuer and the Guarantor, as the case may be, stating whether or not the signer has knowledge of any Default under this Supplemental Indenture, and, if so, specifying each Default and the nature and the status thereof.

The Issuer will deliver to the Trustee, within thirty (30) calendar days of becoming aware of (i) any default in the performance or observance of any covenant, agreement or condition contained in this Supplemental Indenture, or (ii) any Event of Default, an Officers’ Certificate specifying with particularity such Default or Event of Default and further stating what action the Issuer has taken, is taking or proposes to take with respect thereto.

The Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee; provided, that (a) such direction shall not be in conflict with any rule of law or with this Supplemental Indenture, (b) the Trustee may take any other action which is not inconsistent with such direction, (c) the Trustee may decline to take any action that would benefit some Noteholders to the detriment of other Noteholders or otherwise be unduly prejudicial to the Noteholders not joining therein and (d) the Trustee may decline to take any action that would involve the Trustee in personal liability. Prior to taking any such action hereunder, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action.

Upon any such waiver, the Issuer, the Trustee and the Holders of the Notes shall be restored to their former positions and rights hereunder; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as permitted by this Section 6.07, said Default or Event of Default shall for all purposes of the Notes and this Supplemental Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

No provision of this Supplemental Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that:

(a) prior to the occurrence of an Event of Default and after the curing or waiving of all Events of Default which may have occurred:

(i) the duties and obligations of the Trustee shall be determined solely by the express provisions of this Supplemental Indenture and the Trust Indenture Act, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Supplemental Indenture and no implied covenants or obligations shall be read into this Supplemental Indenture and the Trust Indenture Act against the Trustee; and

(f) if any party fails to deliver a notice relating to an event the fact of which, pursuant to this Supplemental Indenture, requires notice to be sent to the Trustee, the Trustee may conclusively rely on its failure to receive such notice as reason to act as if no such event occurred unless a Responsible Officer of the Trustee has actual knowledge thereof or unless the Trustee has otherwise received written notice thereof; and

(g) the Trustee shall not be deemed to have knowledge of any Event of Default hereunder unless a Responsible Officer of the Trustee has actual knowledge thereof or unless the Trustee shall have been notified in writing of such Event of Default by the Issuer or a Holder of Notes.

The obligations of the Issuer under this Section 7.06 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for reasonable expenses, disbursements and advances shall be secured by a lien prior to that of the Notes upon all property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the Holders of particular Notes.

Section 7.09. Eligibility of Trustee.

Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee.

(b) In case at any time any of the following shall occur:

(d) Notwithstanding the replacement of the Trustee pursuant to this Section 7.10, the Issuer’s obligations under Section 7.06 hereof shall continue for the benefit of the retiring Trustee.

Section 7.11. Acceptance by Successor Trustee. Any successor trustee appointed as provided in Section 7.10 hereof shall execute, acknowledge and deliver to the Issuer and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as trustee herein; but, nevertheless, on the written request of the Issuer or of the successor trustee, the trustee ceasing to act shall, upon payment of any amount then due it pursuant to the provisions of Section 7.06 hereof, execute and deliver an instrument transferring to such successor trustee all the rights and powers of the trustee so ceasing to act. Upon request of any such successor trustee, the Issuer shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a lien upon all property and funds held or collected by such trustee as such, except for funds held in trust for the benefit of Holders of particular Notes, to secure any amounts then due it pursuant to the provisions of Section 7.06 hereof.

In case at the time such successor to the Trustee shall succeed to the trusts created by this Supplemental Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by such predecessor trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or any authenticating agent appointed by such successor trustee may authenticate such Notes in the name of the successor trustee; and in all such cases such certificates shall have the full force that is provided in the Notes or in this Supplemental Indenture; provided, that the right to adopt the certificate of authentication of any predecessor Trustee or authenticate Notes in the name of any predecessor Trustee shall apply only to its successor or successors by merger, exchange or consolidation.

Section 7.13. Preferential Collection of Claims. If and when the Trustee shall be or become a creditor of the Issuer (or any other obligor upon the Notes), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of the claims against the Issuer (or any such other obligor).

THE NOTEHOLDERS

Section 8.01. Action by Noteholders. Whenever in this Supplemental Indenture it is provided that the Holders of a specified percentage in aggregate principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action, the Holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Noteholders in person or by agent or proxy appointed in writing, or (b) by the record of the Holders of Notes voting in favor thereof at any meeting of Noteholders, or (c) by a combination of such instrument or instruments and any such record of such a meeting of Noteholders. Whenever the Issuer or the

43

Trustee solicits the taking of any action by the Holders of the Notes, the Issuer or the Trustee may fix in advance of such solicitation a date as the Record Date for determining Holders entitled to take such action. The Record Date, if any, shall be not more than fifteen (15) calendar days prior to the date of commencement of solicitation of such action.

Section 8.02. Proof of Execution by Noteholders. Subject to the provisions of Sections 7.01 and 7.02 hereof, proof of the execution of any instrument by a Noteholder or its agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The holding of Notes shall be proved by the registry of such Notes or by a certificate of the Note Registrar.

Section 8.03. Absolute Owners. The Issuer, the Trustee, any Paying Agent and any Note Registrar may deem the Person in whose name such Note shall be registered upon the Note Register to be, and may treat it as, the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation of ownership or other writing thereon made by any Person other than the Issuer or any Note Registrar) for the purpose of receiving payment of or on account of the principal of (including the Redemption Price upon redemption pursuant to Article 3 hereof), premium, if any, and interest on such Note and for all other purposes; and neither the Issuer nor the Trustee nor any Paying Agent nor any Note Registrar shall be affected by any notice to the contrary.

Notes so owned which have been pledged in good faith may be regarded as outstanding for the purposes of this Section 8.04 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to vote such Notes and that the pledgee is not the Issuer, any other obligor on the Notes or any Affiliate of the Issuer or any such other obligor. In the case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request of the Trustee, the Issuer shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Notes, if any, known by the Issuer to be owned or held by or for the account of any of the above described Persons, and, subject to Section 7.01 hereof, the Trustee shall be entitled to accept such Officers’ Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such determination.

Except as aforesaid, any such action taken by the Holder of any Note shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Note and of any Notes issued in exchange or substitution therefor, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor.

Nothing contained in this Supplemental Indenture or in the Notes shall prevent any consolidation or merger of the Guarantor with or into any other Person or Persons (whether or not affiliated with the Guarantor), or successive consolidations or mergers in which either the Guarantor will be the continuing entity or the Guarantor or its successor or successors shall be a party or parties, or shall prevent any sale, conveyance, transfer or lease of all or substantially all of the property of the Guarantor, to any other Person (whether or not affiliated with the Guarantor); provided, however, that the following conditions are met:

ARTICLE 12

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 12.01. Option to Effect Legal Defeasance or Covenant Defeasance. The Issuer may, at its option and at any time, elect to have either Section 12.02 or 12.03 hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 12.

Section 12.02. Legal Defeasance and Discharge. Upon the Issuer’s exercise under Section 12.01 hereof of the option applicable to this Section 12.02, the Issuer and the Guarantor will, subject to the satisfaction of the conditions set forth in Section 12.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes and Guarantee on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Issuer and the Guarantor will be deemed to have paid and discharged the entire Debt represented by the outstanding Notes and Guarantee, which will thereafter be deemed to be “outstanding” only for the purposes of Section 12.05 hereof and the other sections of this Supplemental Indenture referred to in clauses (a) and (b) below, and to have satisfied all their other obligations under such Notes, the Guarantee and this Supplemental Indenture (and the Trustee, on demand of and at the expense of the Issuer, shall execute proper instruments acknowledging the same), except for the following provisions which will survive until otherwise terminated or discharged hereunder:

(a) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, or interest or premium on, such Notes when such payments are due from the trust referred to in Section 12.04 hereof;

(b) the Issuer’s obligations with respect to such Notes under Article 2 and Section 4.02 hereof;

49

Section 12.03. Covenant Defeasance.

Upon the Issuer’s exercise under Section 12.01 hereof of the option applicable to this Section 12.03, the Issuer and the Guarantor will, subject to the satisfaction of the conditions set forth in Section 12.04 hereof, be released from each of their obligations under the covenants contained in Sections 4.09, 4.10 and 4.11 hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 12.04 hereof are satisfied (hereinafter, “Covenant Defeasance”), and the Notes will thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but will continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Guarantee, the Issuer and the Guarantor may omit to comply with and will have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply will not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Supplemental Indenture and such Notes and Guarantee will be unaffected thereby. In addition, upon the Issuer’s exercise under Section 12.01 hereof of the option applicable to this Section 12.03, subject to the satisfaction of the conditions set forth in Section 12.04 hereof, Sections 6.01(c) and 6.01(d) hereof will not constitute Events of Default.

(a) the Issuer must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm, or firm of independent public accountants, to pay the principal of, premium and interest on, the outstanding Notes on the stated date for payment thereof or on the applicable Redemption Date, as the case may be, and the Issuer must specify whether the Notes are being defeased to such stated date for payment or to a particular Redemption Date;

(b) in the case of an election under Section 12.02 hereof, the Issuer must deliver to the Trustee an Opinion of Counsel confirming that:

in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

50

(c) in the case of an election under Section 12.03 hereof, the Issuer must deliver to the Trustee an Opinion of Counsel confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(d) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit (and any similar concurrent deposit relating to other indebtedness being defeased, discharged or replaced), and the granting of liens to secure such borrowings);

(e) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Supplemental Indenture and the agreements governing any other indebtedness being defeased, discharged or replaced) to which the Issuer or the Guarantor is a party or by which the Issuer or the Guarantor is bound;

(f) the Issuer must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the Issuer with the intent of preferring the Holders of Notes over the other creditors of the Issuer with the intent of defeating, hindering, delaying or defrauding any creditors of the Issuer or others; and

(g) the Issuer must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

Section 12.05. Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions.

Subject to Section 12.06 hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 12.05, the “Trustee”) pursuant to Section 12.04 hereof in respect of the outstanding Notes will be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Supplemental Indenture, to the payment, either directly or through any Paying Agent (including the Issuer acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium and interest, but such money need not be segregated from other funds except to the extent required by law.

The Issuer will pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 12.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

Notwithstanding anything in this Article 12 to the contrary, the Trustee will deliver or pay to the Issuer from time to time upon the request of the Issuer any money or non-callable Government Securities held by it as provided in Section 12.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 12.04(a) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 12.06. Repayment to Issuer.

Any money deposited with the Trustee or any Paying Agent, or then held by the Issuer, in trust for the payment of the principal of, premium or interest on, any Note and remaining unclaimed for two years after such principal, premium or interest has become due and payable shall be paid to the Issuer on its request or (if then held by the Issuer) will be discharged from such trust; and the Holder of such Note will thereafter be permitted to look only to the Issuer for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuer as trustee thereof, will thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Issuer cause to be published once, in the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which will not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Issuer.

Section 12.07. Reinstatement.

If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable Government Securities in accordance with Section 12.02 or 12.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Issuer’s and the Guarantor’s obligations under this Supplemental Indenture and the Notes and the Guarantee will be revived and reinstated as though no deposit had occurred pursuant to Section 12.02 or 12.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 12.02 or 12.03 hereof, as the case may be; provided, however, that, if the Issuer makes any payment of principal of, premium or interest on, any Note following the reinstatement of its obligations, the Issuer will be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

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 the principal, premium, if any, and interest on the Notes and all other costs provided for under this Supplemental Indenture or as provided in Article 7 hereof.

If any Holder or the Trustee is required by any court or otherwise to return to either the Issuer or the Guarantor, or any trustee or similar official acting in relation to either the Issuer or the Guarantor, any amount paid by the Issuer 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

56

of Notes and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof 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 6 hereof, 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 15.02. Execution and Delivery of Guarantee. To evidence the Guarantee set forth in Section 15.01 hereof, the Guarantor agrees that a notation of the 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 Supplemental Indenture shall be executed on behalf of the Guarantor by an Officer of the Guarantor.

The Guarantor agrees that the Guarantee set forth in this Article 15 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.

If an officer whose 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.

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

Section 15.03. 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 15 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 Issuer, 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.
