ARTICLE 2

Issue, Description, Execution, Registration and Exchange of Notes

     Section 2.01. Designation Amount and Issue of Notes. The Notes shall be designated as the “4.00% Convertible Senior Notes due 2035.” Upon the execution of this Indenture, and from time to time thereafter, Notes may be executed by the Issuer and delivered to the Trustee for authentication, and the Trustee shall thereupon authenticate and deliver Notes upon a written order of the Issuer, such order signed by two Officers, without any further action by the Issuer hereunder.

     The aggregate principal amount of Notes which may be authenticated and delivered under this Indenture is initially limited to $200,000,000 (or $250,000,000 if the Initial Purchaser’s option set forth in the Purchase Agreement is exercised in full). The Issuer may, without the consent of the holders of Notes, issue additional Notes (the “Additional Notes”) from time to time in the future with the same terms and the same CUSIP number as the Notes originally issued under this Indenture (the “Initial Notes”) in an unlimited principal amount, provided that such Additional Notes must be part of the same issue as 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 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 that action as a single class.

     Section 2.02. Form of Notes. The Notes and the Trustee’s certificate of authentication to be borne by such Notes shall be substantially in the form set forth in Exhibit A hereto. 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 this Indenture and, to the extent applicable, the Issuer and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby.

     Any of the Notes may have such letters, numbers or other marks of identification and such notations, legends, endorsements or changes as the officers executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of this Indenture, or as may be required by the Custodian, the Depositary or by the National Association of Securities Dealers, Inc. in order for the Notes to be tradable on The PORTAL Market or as may be required for the Notes to be tradable on any other market developed for trading of securities pursuant to Rule 144A or as may be required to comply with any applicable law or with any rule or regulation made pursuant thereto or with any rule or regulation of any securities exchange or automated quotation system on which the Notes may be listed, or to conform to usage, or to indicate any special limitations or restrictions to which any particular Notes are subject.

     So long as the Notes are eligible for book-entry settlement with the Depositary, or unless otherwise required by law, or otherwise contemplated by Section 2.05(b), all of the Notes will be represented by one or more Notes in global form registered in the name of the Depositary or the nominee of the Depositary (a “Global Note”). The transfer and exchange of beneficial interests in any such Global Note shall be effected through the Depositary in accordance with this Indenture and the applicable procedures of the Depositary. Except as provided in Section

2.05(b), beneficial owners of a Global Note shall not be entitled to have certificates registered in their names, will not receive or be entitled to receive physical delivery of certificates in definitive form and will not be considered holders of such Global Note.

     Any Global Note shall represent such of the outstanding Notes as shall be specified therein and shall provide that it shall represent the aggregate amount of outstanding Notes from time to time endorsed thereon and that the aggregate amount of outstanding Notes represented thereby may from time to time be increased or reduced to reflect redemptions, repurchases, conversions, exchanges or transfers permitted hereby. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the amount of outstanding Notes represented thereby shall be made by the Trustee or the Custodian, at the direction of the Trustee, in such manner and upon instructions given by the holder of such Notes in accordance with this Indenture. Payment of principal of, and interest on, any Global Note shall be made to the holder of such Note.

     Section 2.03. Date and Denomination of Notes; Payments of Interest. The Notes shall be issuable in registered form without coupons in denominations of $1,000 principal amount and integral multiples thereof. Each Note shall be dated the date of its authentication and shall bear interest from the date specified on the face of the form of Note attached as Exhibit A hereto. Interest on the Notes shall be computed on the basis of a 360-day year comprised of twelve 30-day months.

     The Person in whose name any Note (or its Predecessor Note) is registered on the Note Register at 5:00 p.m., New York City time, on any Record Date with respect to any Interest Payment Date shall be entitled to receive the interest payable on such Interest Payment Date; provided that interest payable on the Maturity Date shall be payable to the Person to whom principal is payable; and provided, further that if an Interest Payment Date falls on or prior to a Redemption Date, a Fundamental Change Repurchase Date or a Repurchase Date, as the case may be, the semi-annual payment of interest becoming due on such Interest Payment Date shall be payable to the holder of such Note registered as such on the related Record Date. Interest shall be payable at the office of the Issuer maintained by the Issuer for such purposes in the Borough of Manhattan, The City of New York, which shall initially be an office or agency of the Trustee. The Issuer 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 Note Register; provided, however, that a holder of any Notes in certificated form in the aggregate principal amount of more than $5.0 million may specify by written notice to the Issuer that it pay interest by wire transfer of immediately available funds to the account specified by the Noteholder in such notice, or (ii) on any Global Note by wire transfer of immediately available funds to the account of the Depositary or its nominee. If a payment date is not a Business Day, payment shall be made on the next succeeding Business Day, and no additional interest shall accrue thereon. The term “Record Date” with respect to any Interest Payment Date shall mean the June 1 or the December 1 next preceding the applicable Interest Payment Date.

     Any interest on any Note which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Noteholder registered as such on the relevant Record Date, and such Defaulted

Interest shall be paid by the Issuer, at its election in each case, as provided in clause (1) or (2) below:

     (1) The Issuer may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes (or their respective Predecessor 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 Issuer 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, unless the Trustee shall consent to an earlier date), and at the same time the Issuer shall deposit with the Trustee an amount of money 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 money 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 Trustee 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 (unless, the Trustee shall consent to an earlier date). The Trustee shall promptly notify the Issuer of such special record date and, in the name and at the expense of the Issuer, shall cause notice of the proposed payment of such Defaulted Interest and the special record date therefor to be mailed, first-class postage prepaid, to each holder at its address as it appears in the Note Register, not less than ten (10) calendar days prior to such special record date (unless, the Trustee shall consent to an earlier 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 (or their respective Predecessor 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 (2) of this Section 2.03.

     (2) The Issuer 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 Issuer to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

     Section 2.04. Execution of Notes. The Notes shall be signed in the name and on behalf of the Issuer by the manual or facsimile signature of an Officer. Only such Notes as shall bear thereon a certificate of authentication substantially in the form set forth on the form of Note attached as Exhibit A hereto, manually executed by the Trustee (or an authenticating agent appointed by the Trustee as provided by Section 15.11), shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. Such certificate by the Trustee (or such an authenticating agent) upon any Note executed by the Issuer shall be conclusive evidence that the Note so authenticated has been duly authenticated and delivered hereunder and that the holder is entitled to the benefits of this Indenture.

     In case any Officer who shall have signed any of the Notes shall cease to be such Officer 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, 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, although at the date of the execution of this Indenture any such person was not such an Officer.

     Section 2.05. Exchange and Registration of Transfer of Notes; Restrictions on Transfer. (a) The Issuer shall cause to be kept at the Corporate Trust Office a register (the register maintained in such office and in any other office or agency of the Issuer designated pursuant to Section 4 being herein sometimes collectively referred to as the “Note Register”) in which, subject to such reasonable regulations as it may prescribe, the Issuer shall provide for the registration of Notes and of transfers of Notes. The Note Register shall be in written form or in any form capable of being exchanged into written form within a reasonably prompt period of time. The Trustee is hereby appointed “Note Registrar” for the purpose of registering Notes and transfers of Notes as herein provided. The Issuer may appoint one or more co-registrars in accordance with Section 4.02.

     Upon surrender for registration of transfer of any Note to the Note Registrar or any co-registrar, and satisfaction of the requirements for such transfer set forth in this Section 2.05, the Issuer shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denominations and of a like aggregate principal amount and bearing such restrictive legends as may be required by this Indenture.

     Notes may be exchanged for other Notes of any authorized denominations and of a like aggregate principal amount, upon surrender of the Notes to be exchanged at any such office or agency maintained by the Issuer pursuant to Section 4.02. Whenever any Notes are so surrendered for exchange, the Issuer shall execute, and the Trustee shall authenticate and deliver, the Notes which the Noteholder making the exchange is entitled to receive bearing registration numbers not contemporaneously outstanding.

     All Notes issued upon any registration of transfer or exchange of Notes shall be the valid obligations of the Issuer, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Notes surrendered upon such registration of transfer or exchange.

     All Notes presented or surrendered for registration of transfer or exchange, repurchase or conversion shall (if so required by the Issuer or the Note Registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Issuer, and the Notes shall be duly executed by the Noteholder thereof or its attorney duly authorized in writing.

     No service charge shall be made to any holder for any registration of transfer or exchange of Notes, but the Issuer may require payment by the holder of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes.

     In connection with the redemption of the Notes in part, neither the Issuer nor the Trustee nor any Note Registrar shall be required to issue or register the transfer or exchange of (a) any Notes for a period of fifteen (15) calendar days next preceding any selection of Notes to be redeemed 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 (b) any Notes or portions thereof called for redemption pursuant to Section 3.02, except the unredeemed portion of any Note redeemed in part.

     (b) The following provisions shall apply only to Global Notes:

     (i) Each Global Note authenticated under this Indenture shall be registered in the name of the Depositary or a nominee thereof and delivered to such Depositary or a nominee thereof or Custodian therefor, and each such Global Note shall constitute a single Note for all purposes of this Indenture.

     (ii) Notwithstanding any other provision in this Indenture, no Global Note may be exchanged in whole or in part for Notes registered, and no transfer of a Global Note in whole or in part may be registered, in the name of any Person other than the Depositary or a nominee thereof unless (1) the Depositary (x) has notified the Issuer that it is unwilling or unable to continue as Depositary for such Global Note or (y) has ceased to be a clearing agency registered under the Exchange Act, and a successor depositary has not been appointed by the Issuer within ninety (90) calendar days, (2) an Event of Default has occurred and is continuing or (3) the Issuer, in its sole discretion, notifies the Trustee in writing that it no longer wishes to have all the Notes represented by Global Notes. Any Global Note exchanged pursuant to clause (1) or (2) above shall be so exchanged in whole and not in part and any Global Note exchanged pursuant to clause (3) above may be exchanged in whole or from time to time in part as directed by the Issuer. Any Note issued in exchange for a Global Note or any portion thereof shall be a Global Note; provided that any such Note so issued that is registered in the name of a Person other than the Depositary or a nominee thereof shall not be a Global Note.

     (iii) Notes issued in exchange for a Global Note or any portion thereof pursuant to clause (ii) above shall be issued in definitive, fully registered form, without interest coupons, shall have an aggregate principal amount equal to that of such Global Note or portion thereof to be so exchanged, shall be registered in such names and be in such authorized denominations as the Depositary shall designate and shall bear any legends required hereunder. Any Global Note to be exchanged in whole shall be surrendered by the Depositary to the Trustee, as Note Registrar. With regard to any Global Note to be exchanged in part, either such Global Note shall be so surrendered for exchange or, if the Trustee is acting as Custodian for the Depositary or its nominee with respect to such Global Note, the principal amount thereof shall be reduced, by an amount equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and make available for delivery the Note issuable on such exchange to or upon the written order of the Depositary or an authorized representative thereof.

     (iv) In the event of the occurrence of any of the events specified in clause (ii) above, the Issuer will promptly make available to the Trustee a reasonable supply of certificated Notes in definitive, fully registered form, without interest coupons.

     (v) Neither any members of, or participants in, the Depositary (“Agent Members”) nor any other Persons on whose behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Note registered in the name of the Depositary or any nominee thereof, and the Depositary or such nominee, as the case may be, may be treated by the Issuer, the Trustee and any agent of the Issuer or the Trustee as the absolute owner and holder of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Issuer, the Trustee or any agent of the Issuer or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or such nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any other Person on whose behalf an Agent Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a holder of any Note.

     (vi) At such time as all interests in a Global Note have been redeemed, repurchased, converted or exchanged for Notes in certificated form, such Global Note shall, upon receipt thereof, be canceled by the Trustee in accordance with standing procedures and instructions existing between the Depositary and the Custodian. At any time prior to such cancellation, if any interest in a Global Note is redeemed, repurchased, converted or exchanged for Notes in certificated form, the principal amount of such Global Note shall, in accordance with the standing procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced, and an endorsement shall be made on such Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction.

     (c) Every Note (and all securities issued in exchange therefor or in substitution thereof) that bears or is required under this Section 2.05(c) to bear the legend set forth in this Section 2.05(c) (together with any Common Stock issued upon conversion of the Notes, collectively, the “Restricted Securities”) shall be subject to the restrictions on transfer set forth in this Section 2.05(c) (including those set forth in the legend below) unless such restrictions on transfer shall be waived by written consent of the Issuer, and the holder of each such Restricted Security, by such Noteholder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. As used in this Section 2.05(c), the term “transfer” means any sale, pledge, loan, transfer or other disposition whatsoever of any Restricted Security or any interest therein.

     Until the expiration of the holding period applicable to sales of Restricted Securities under Rule 144(k) under the Securities Act (or any successor provision), any certificate evidencing a Restricted Security shall bear a legend in substantially the following form, unless such Restricted Security has been sold pursuant to a registration statement that has been declared effective under the Securities Act (and which continues to be effective at the time of such transfer) or sold pursuant to Rule 144 under the Securities Act or any similar provision then in force, or unless otherwise agreed by the Issuer in writing, with written notice thereof to the Trustee:

THE SECURITY EVIDENCED BY THIS CERTIFICATE HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS, AND MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST THEREIN, THE HOLDER:

     (1) REPRESENTS THAT IT IS A “QUALIFIED INSTITUTIONAL BUYER” AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT AND IS PURCHASING IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT;

     (2) AGREES THAT IT WILL NOT WITHIN TWO YEARS AFTER THE ORIGINAL ISSUANCE OF THIS SECURITY RESELL OR OTHERWISE TRANSFER THE SECURITY EVIDENCED HEREBY OR ANY COMMON STOCK ISSUABLE UPON CONVERSION OF SUCH SECURITY EXCEPT (A) TO THE ISSUER OR ANY SUBSIDIARY THEREOF, (B) FOR AS LONG AS THIS SECURITY IS ELIGIBLE FOR RESALE UNDER RULE 144A UNDER THE SECURITIES ACT, TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A THEREUNDER, (C) PURSUANT TO ANY OTHER AVAILABLE EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT, INCLUDING THE EXEMPTION PROVIDED BY RULE 144 THEREUNDER (IF AVAILABLE), OR (D) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT AND WHICH CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH TRANSFER; AND

     (3) AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THE SECURITY EVIDENCED HEREBY IS TRANSFERRED (OTHER THAN A TRANSFER PURSUANT TO CLAUSE 2(D) ABOVE) A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.

IN CONNECTION WITH ANY TRANSFER OF THE SECURITY EVIDENCED HEREBY WITHIN TWO YEARS AFTER THE ORIGINAL ISSUANCE OF SUCH SECURITY (OTHER THAN A TRANSFER PURSUANT TO CLAUSE 2(D) ABOVE), THE HOLDER MUST CHECK THE APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF RELATING TO THE MANNER OF SUCH TRANSFER AND SUBMIT THIS CERTIFICATE TO THE TRUSTEE (OR ANY SUCCESSOR TRUSTEE, AS APPLICABLE). IF THE PROPOSED TRANSFER IS PURSUANT TO CLAUSE 2(C) ABOVE, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO THE TRUSTEE (OR ANY SUCCESSOR TRUSTEE, AS APPLICABLE), SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS THE ISSUER OR THE TRUSTEE MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. THIS LEGEND WILL BE REMOVED UPON THE EARLIER OF THE TRANSFER OF THE SECURITY EVIDENCED HEREBY PURSUANT TO CLAUSE 2(D) ABOVE OR THE EXPIRATION OF TWO YEARS FROM THE ORIGINAL ISSUANCE OF THE SECURITY EVIDENCED HEREBY.

     Any Notes that are Restricted Securities and as to which such restrictions on transfer shall have expired in accordance with their terms or as to conditions for removal of the foregoing legend set forth therein have been satisfied may, upon surrender of such Note for exchange to the Note Registrar in accordance with the provisions of this Section 2.05, be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which shall not bear the restrictive legend required by this Section 2.05(c). If such Restricted Security surrendered for exchange is represented by a Global Note bearing the legend set forth in this Section 2.05(c), the principal amount of the legended Global Note shall be reduced by the appropriate principal amount and the principal amount of a Global Note without the legend set forth in this Section 2.05(c) shall be increased by an equal principal amount. If a Global Note without the legend set forth in this Section 2.05(c) is not then outstanding, the Issuer shall execute and the Trustee shall authenticate and deliver an unlegended Global Note to the Depositary.

     In the event Rule 144(k) under the Securities Act (or any successor provision) is amended to shorten the two-year period under Rule 144(k), then, the references in the restrictive legends set forth above to “TWO YEARS,” and in the corresponding transfer restrictions described above, and in the Notes and the shares of Common Stock will be deemed to refer to such shorter period, from and after receipt by the Trustee of an Officers’ Certificate and an Opinion of Counsel to that effect. As soon as reasonably practicable after the Issuer knows of the effectiveness of any such amendment to shorten the two-year period under Rule 144(k), unless such changes would otherwise be prohibited by, or would cause a violation of, the federal securities laws applicable at the time, the Issuer will provide to the Trustee an Officers’ Certificate and an Opinion of Counsel as to the effectiveness of such amendment and the effectiveness of such change to the restrictive legends and transfer restrictions.

     (d) The Issuer or any of its affiliates may, to the extent permitted by applicable law, at any time purchase Notes in the open market, by tender at any price or by private agreement. Any Note purchased by the Issuer or any of its affiliates shall be surrendered to the Trustee for cancellation. Any Notes surrendered for cancellation may not be reissued or resold and shall be canceled promptly.

     (e) The Trustee shall have no responsibility or obligation to any Agent Members or any other Person with respect to the accuracy of the books or records, or the acts or omissions, of the Depositary or its nominee or of any participant or member thereof, with respect to any ownership interest in the Notes or with respect to the delivery to any Agent Member or other Person (other than the Depositary) of any notice (including any notice of redemption) or the payment of any amount, under or with respect to such Notes. 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 Depository. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its Agent Members.

     The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or

among Agent Members in any Global Indenture) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

     Section 2.06. 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 or has been properly tendered for repurchase on a Repurchase Date or a Fundamental Change Repurchase Date (and not withdrawn), as the case may be, or is to be converted pursuant to this Indenture, shall become mutilated or be destroyed, lost or stolen, the Issuer may, instead of issuing a substitute Note, pay or authorize the payment of or authorize the conversion of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion 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 or Conversion Agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

     Every substitute Note issued pursuant to the provisions of this Section 2.06 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 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 or repurchase 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 exchange or redemption or repurchase of negotiable instruments or other securities without their surrender.

     Section 2.07. 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 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 Indenture as Notes in certificated form authenticated and delivered hereunder.

     Section 2.08. Cancellation of Notes. All Notes surrendered for the purpose of payment, redemption, repurchase, conversion, exchange or registration of transfer shall, if surrendered to the Issuer or any paying agent to whom Notes may be presented for payment (the “Paying Agent”) or Conversion 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 Indenture. The Trustee shall dispose of such canceled Notes in accordance with its customary procedures. If the Issuer shall acquire any of the Notes, such acquisition shall not operate as a redemption, repurchase or satisfaction of the indebtedness represented by such Notes unless and until the same are delivered to the Trustee for cancellation.

     Section 2.09. 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.

ARTICLE 3
Redemption and Repurchase of Notes

     Section 3.01. Optional Redemption of Notes. The Issuer shall not have the right to redeem any Notes prior to January 15, 2011, except to preserve its status as a real estate

investment trust. If the Issuer determines it is necessary to redeem the Notes in order to preserve its status as a real estate investment trust, the Issuer may, upon the notice set forth in Section 3.02, redeem the Notes for cash, in whole or in part, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed plus unpaid interest, if any, accrued thereon to, but excluding, the Redemption Date; provided that, in connection with any such redemption, the Issuer shall provide the Trustee with an Officers’ Certificate evidencing that the Board of Directors has, in good faith, made the determination that it is necessary to redeem the Notes in order to preserve the Issuer’s status as a real estate investment trust.

     The Issuer shall have the right to redeem the Notes for cash, in whole or in part at any time or from time to time, on or after January 15, 2011 upon the notice set forth in Section 3.02, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed plus unpaid interest, if any, accrued thereon to, but excluding, the Redemption Date.

     In connection with any redemption in accordance with the provisions of this Section 3.01, if an Interest Payment Date falls on or prior to the Redemption Date, then the interest payable on such Interest Payment Date shall be paid to the holders of record of the Notes on the applicable Record Date instead of the holders surrendering the Notes for redemption.

     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, 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, the Trustee in the name of and at the expense of the Issuer, shall mail or cause to be mailed 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 Note Register; provided that if the Issuer makes such request of the Trustee, the text of the notice shall be prepared by the Issuer. Such mailing shall be by first class mail. 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. Concurrently with the mailing of any such notice of redemption, the Issuer shall issue a press release announcing such redemption, the form and content of which press release shall be determined by the Issuer in its sole discretion. The failure to issue any such press release or any defect therein shall not affect the validity of the redemption notice or any of the proceedings for the redemption of any Note called for redemption.

     Each such notice of redemption shall specify: (i) the aggregate principal amount of Notes to be redeemed, (ii) the CUSIP number or numbers of the Notes being redeemed, (iii) the date fixed for redemption (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, (iv) that interest accrued and unpaid to, but excluding, the date fixed for redemption 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, (vii) that the holder has a right to convert the Notes called for redemption, (viii) the Conversion Rate on the

date of such notice and (ix) the time and date on which the right to convert such Notes or portions thereof pursuant to this Indenture will expire. 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 shall 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 thirty (30) calendar days (or such shorter period of time as may be acceptable to the Trustee) prior to the Redemption Date.

     On or prior to the Redemption Date specified in the notice of redemption given as provided in this Section 3.02, the Issuer shall 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) an amount of money in immediately available funds sufficient to redeem on the Redemption Date all the Notes (or portions thereof) so called for redemption (other than those theretofore surrendered for exchange) at the appropriate redemption price, together with accrued interest to, but excluding, the Redemption Date; 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 and accrued interest to, but excluding, the Redemption Date. If any Note called for redemption is converted pursuant hereto prior to such Redemption Date, any money deposited with the Paying Agent or so segregated and held in trust for the redemption of such Note shall be paid to the Issuer or, if then held by the Issuer, shall be discharged from such trust.

     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 $1,000 or multiples thereof) by lot, on a pro rata basis or by another method the Trustee deems fair and appropriate. If any Note selected for redemption in part is submitted for conversion in part after such selection, the portion of such Note submitted for conversion shall be deemed (so far as may be possible) to be the portion to be selected for redemption. The Notes (or portions thereof) so selected for redemption shall be deemed duly selected for redemption for all purposes hereof, notwithstanding that any such Note is submitted for conversion in part before the mailing of the notice of redemption.

     Upon any redemption of less than all of the outstanding Notes, the Issuer and the Trustee may (but need not), solely for purposes of determining the pro rata allocation among such Notes that are outstanding at the time of redemption, treat as outstanding any Notes surrendered for conversion during the period in which Notes are selected for redemption.

     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, the Notes or portion of Notes with respect to which such notice has been given shall, unless converted pursuant to the terms hereof, become due and payable on the date fixed for redemption at the place or places stated in such

notice at the redemption price, plus interest accrued to, but excluding, the Redemption Date, and unless the Issuer shall default in the payment of the amounts owing on the Notes upon such redemption, interest on the Notes or portion of Notes so called for redemption shall cease to accrue on and after such date and, except as provided in Section 7.05 and Section 11.02, the Notes shall cease to be entitled to any benefit or security under this Indenture, and the holders thereof shall have no right in respect of such Notes except the right to receive the redemption price thereof plus accrued and unpaid interest to, but excluding, the Redemption Date. 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.

     Notes and portions of Notes that are to be redeemed pursuant to this Article 3 shall be convertible by the Holder thereof until 5:00 p.m., New York City time, on the second Business Day immediately preceding the Redemption Date, unless the Issuer shall fail to pay the redemption price.

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

     Section 3.05. Repurchase at Option of Holders Upon a Fundamental Change.

     (a) If there shall occur a Fundamental Change at any time prior to the Maturity Date, then each Noteholder shall have the right to require the Issuer to repurchase its Notes for cash, in whole or in part (in principal amounts of $1,000 and integral multiples thereof), on a date (the “Fundamental Change Repurchase Date”) specified by the Issuer (which date shall be not more than thirty (30) Business Days after the Issuer Repurchase Notice Date related to such Fundamental Change) at a repurchase price equal to 100% of the principal amount of the Notes being repurchased, plus accrued and unpaid interest to, but excluding, the Fundamental Change Repurchase Date; provided that if an Interest Payment Date falls on or prior to the Fundamental Change Repurchase Date, then, with respect to any Note in respect of which the holder thereof shall have submitted a Repurchase Notice, the interest payable on such Interest Payment Date shall be paid to the holder of record of such Note on the applicable Record Date instead of the holder surrendering such Note for repurchase on such Fundamental Change Repurchase Date.

     (b) Within 10 days after the occurrence of a Fundamental Change, the Issuer shall mail or cause to be mailed to all holders of record on the date of the Fundamental Change (and to beneficial owners as required by applicable law) an Issuer Repurchase Notice as set forth in Section 3.07 with respect to such Fundamental Change. The Issuer shall also deliver a copy of the Issuer Repurchase Notice to the Trustee and the Paying Agent at such time as it is mailed to Noteholders. In addition to the mailing of such Issuer Repurchase Notice, the Issuer shall disseminate a press release through Dow Jones & Company, Inc., Bloomberg Business News or a substantially similar news organization announcing the occurrence of such Fundamental Change and publish such information in a newspaper of general circulation in The City of New

York or on the Issuer’s web site, or through such other public medium as the Issuer shall deem appropriate at such time. The failure to issue any such press release or any defect therein shall not affect the validity of the Issuer Repurchase Notice or any proceedings for the repurchase of any Note which any Noteholder may elect to have the Issuer redeem as provided in this Section 3.05.

     No failure of the Issuer to give the foregoing notices and no defect therein shall limit the Noteholders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section 3.05.

     (c) In order to exercise its repurchase right, the holder must deliver to the Paying Agent, prior to the close of business on the Fundamental Change Repurchase Date, a written notice of repurchase (the “Repurchase Notice”). Such Repurchase Notice shall state: (A) the certificate number (if the Note is in certificated form) of the Note which the holder will deliver to be repurchased, (B) the portion of the principal amount of the Note which the holder will deliver to be repurchased, in multiples of $1,000, provided that the remaining principal amount of Notes is in an authorized denomination and (C) that such Note shall be repurchased pursuant to the terms and conditions specified in the Note and in this Indenture. Any Repurchase Notice provided in respect of a beneficial interest in a Global Note shall be required to comply with the applicable procedures of the Depositary.

     (d) The Issuer, if so requested, shall repurchase from the holder thereof, pursuant to this Section 3.05, a portion of a Note, if the principal amount of such portion is $1,000 or a whole multiple of $1,000. Provisions of this Indenture that apply to the repurchase of all of a Note also apply to the repurchase of such portion of such Note.

     (e) Notwithstanding the foregoing, no Notes may be repurchased by the Issuer pursuant to this Section 3.05 if there has occurred and is continuing an Event of Default with respect to the Notes (other than a default in the payment of the repurchase price for the Notes to be repurchased).

     (f) The Paying Agent shall promptly notify the Issuer of the receipt by it of any Repurchase Notice or written notice of withdrawal thereof. All questions as to the validity, eligibility (including time of receipt) and acceptance of any Note for repurchase shall be determined by the Issuer, whose determination shall be final and binding absent manifest error.

     (g) Payment of the repurchase price for a Note for which a Repurchase Notice has been delivered and not withdrawn is conditioned upon book-entry transfer or delivery of the Notes, together with necessary endorsements, to the Paying Agent. Such repurchase price shall be paid to such holder, subject to receipt of funds and/or Notes by the Paying Agent, within two (2) Business Days following the later of (x) the Fundamental Change Repurchase Date with respect to such Note (provided the holder has satisfied the conditions in this Section 3.05) and (y) the time of book-entry transfer or delivery of such Note or beneficial interest therein to the Paying Agent by the holder thereof.

     Section 3.06. Repurchase of Notes at the Option of Holders.

     (b) On or before the twentieth (20th) Business Day immediately preceding each Repurchase Date, the Issuer shall mail or cause to be mailed to all holders of record on such date (and to beneficial owners as required by applicable law) an Issuer Repurchase Notice as set forth in Section 3.07. The Issuer shall also deliver a copy of the Issuer Repurchase Notice to the Trustee and the Paying Agent at such time as it is mailed to Noteholders.

     (d) The Issuer, if so requested, shall repurchase from the holder thereof, pursuant to this Section 3.06, a portion of a Note, if the principal amount of such portion is $1,000 or a whole multiple of $1,000. Provisions of this Indenture that apply to the repurchase of all of a Note also apply to the repurchase of such portion of such Note.

     (e) Notwithstanding the foregoing, no Notes may be repurchased by the Issuer pursuant to this Section 3.06 if there has occurred and is continuing an Event of Default with

     (10) state that, unless the Issuer defaults in making payment of the repurchase price, interest on Notes in respect of which a Repurchase Notice shall have been submitted and not withdrawn will cease to accrue on and after the Fundamental Change Repurchase Date or the Repurchase Date, as the case may be; and

Such will be the case whether or not book-entry transfer of the Note to the Paying Agent is made or whether or not Notes in certificated form, together with necessary endorsements, are delivered to the Paying Agent.

     (c) Anything in this Section 4.04 to the contrary notwithstanding, the Issuer may, at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other reason, pay or cause to be paid to the Trustee all sums held in trust by the Issuer or any Paying Agent hereunder as required by this Section 4.04, such sums to be held by the Trustee upon the trusts herein contained and upon such payment by the Issuer or any Paying Agent to the Trustee, the Issuer or such Paying Agent shall be released from all further liability with respect to such sums.

     (d) Anything in this Section 4.04 to the contrary notwithstanding, the agreement to hold sums in trust as provided in this Section 4.04 is subject to Section 11.02 and Section 11.03.

     Section 4.05. Existence. Subject to Article 10, the Issuer will do or cause to be done all things necessary to preserve and keep in full force and effect its existence and rights (charter and statutory); provided that the Issuer shall not be required to preserve any such right if the Issuer shall determine that the preservation thereof is no longer desirable in the conduct of its business and that the loss thereof is not disadvantageous in any material respect to the Noteholders.

Securities Act upon the request of any holder or beneficial holder of the Notes or such shares of Common Stock, all to the extent required to enable such holder or beneficial holder to sell its Notes or shares of Common Stock without registration under the Securities Act within the limitation of the exemption provided by Rule 144A.

     Section 4.08. Stay, Extension and Usury Laws. 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 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 4.09. Compliance Certificate. The Issuer shall deliver to the Trustee, within one hundred twenty (120) calendar days after the end of each fiscal year of the Issuer, a certificate signed by any of the principal executive officer, principal financial officer or principal accounting officer of the Issuer, stating whether or not to the knowledge of the signer thereof the Issuer is in default in the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and, if the Issuer shall be in default, specifying all such defaults and the nature and the status thereof of which the signer may have knowledge.

     The Issuer will deliver to the Trustee, promptly upon becoming aware of (i) any default in the performance or observance of any covenant, agreement or condition contained in this 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.

     Any notice required to be given under this Section 4.09 shall be delivered to a Responsible Officer of the Trustee at its Corporate Trust Office.

     Section 4.10. Additional Interest Notice. In the event that the Issuer is required to pay Additional Interest to holders of Notes pursuant to the Registration Rights Agreement, the Issuer will provide written notice (“Additional Interest Notice”) to the Trustee of its obligation to pay Additional Interest no later than fifteen (15) calendar days prior to the proposed payment date for Additional Interest, and the Additional Interest Notice shall set forth the amount of Additional Interest to be paid by the Issuer on such payment date. The Trustee shall not at any time be under any duty or responsibility to any holder of Notes to determine the Additional Interest, or with respect to the nature, extent or calculation of the amount of Additional Interest when made, or with respect to the method employed in such calculation of the Additional Interest.

ARTICLE 5

     Section 5.02. Preservation and Disclosure of Lists.

     (a) The Trustee shall preserve, in as current a form as is reasonably practicable, all information as to the names and addresses of the holders of Notes contained in the most recent list furnished to it as provided in Section 5.01 or maintained by the Trustee in its capacity as Note Registrar or co-registrar in respect of the Notes, if so acting. The Trustee may destroy any list furnished to it as provided in Section 5.01 upon receipt of a new list so furnished.

     (b) The rights of Noteholders to communicate with other holders of Notes with respect to their rights under this Indenture or under the Notes, and the corresponding rights and duties of the Trustee, shall be as provided by the Trust Indenture Act.

     (c) Every Noteholder agrees with the Issuer and the Trustee that neither the Issuer nor the Trustee nor any agent of either of them shall be held accountable by reason of any disclosure of information as to names and addresses of holders of Notes made pursuant to the Trust Indenture Act.

     Section 5.03. Reports by Trustee. (a) Within sixty (60) calendar days after May 15 of each year commencing with the year 2006, the Trustee shall transmit to holders of Notes such reports dated as of May 15 of the year in which such reports are made concerning the Trustee and its actions under this Indenture as may be required pursuant to Section 313(a) of the Trust Indenture Act at the times and in the manner provided pursuant thereto.

The Issuer will promptly notify the Trustee in writing if the Notes are listed on any stock exchange or automated quotation system or delisted therefrom.

     Section 5.04. Reports by Issuer. Whether or not the Issuer is subject to Section 13 or 15(d) of the Exchange Act and for so long as any Notes are outstanding, within the time periods

Delivery of such reports, information 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 Issuer’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on an Officers’ Certificate).

ARTICLE 6

     (h) the Issuer or any Significant Subsidiary of the Issuer pursuant to or under or within meaning of any Bankruptcy Law:

     (i) commences a voluntary case or proceeding seeking liquidation, reorganization or other relief with respect to it or its debts or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of it or any substantial part of its property; or

     (iii) orders the liquidation of the Issuer or any Significant Subsidiary of the Issuer;

and, in each case in this clause (j), the order or decree remains unstayed and in effect for sixty (60) calendar days.

     If an Event of Default (other than an Event of Default specified in Section 6.01(h), 6.01(i) and 6.01(j)) with respect to the Issuer) shall occur and be continuing, unless the principal of all of the Notes shall have already become due and payable, either the Trustee or the holders of at least twenty-five percent (25%) in aggregate principal amount of the Notes then outstanding, by notice in writing to the Issuer (and to the Trustee if given by Noteholders), may declare the principal of, and interest (including Additional Interest, if any) accrued and unpaid on, all the Notes to be immediately due and payable, and upon any such declaration the same shall be immediately due and payable.

     If an Event of Default specified in Section 6.01(h), 6.01(i) or 6.01(j) occurs with respect to the Issuer, the principal of, and interest (including Additional Interest, if any) accrued and unpaid on, all the Notes shall be immediately and automatically due and payable without necessity of further action.

     If, at any time after the principal of and interest on the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter provided, holders of a majority in aggregate principal amount of the Notes then outstanding on behalf of the holders of all of the Notes then outstanding, by written notice to the Issuer and to the Trustee, may waive all defaults or Events of Default and rescind and annul such declaration and its consequences subject to Section 6.07 if: (a) such rescission would not conflict with any judgment or decree of a court of competent jurisdiction; (b) interest on overdue installments of interest (including Additional Interest) (to the extent that payment of such interest is lawful) and on overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid; (c) the Issuer has paid the Trustee its reasonable compensation and reimbursed the Trustee for its expenses, disbursements and advances pursuant to Section 7.06; and (d) all Events of Default, other than the nonpayment of the principal amount and any accrued and unpaid interest that has become due solely because of such acceleration, have been cured or waived. 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. The Issuer shall notify in writing a Responsible Officer of the Trustee, promptly upon becoming aware thereof, of any Event of Default, as provided in Section 4.09.

     In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned because of such waiver or rescission and annulment or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Issuer, the holders of Notes, and the Trustee shall be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Issuer, the holders of Notes, and the Trustee shall continue as though no such proceeding had been taken.

     Section 6.02. Payments of Notes on Default; Suit Therefor. The Issuer covenants that in the case of an Event of Default pursuant to Section 6.01(a) or 6.01(b), upon demand of the Trustee, the Issuer will pay to the Trustee, for the benefit of the holders of the Notes, (i) the whole amount that then shall be due and payable on all such Notes for principal or interest, as the case may be, with interest upon the overdue principal and premium, if any, and (to the extent that payment of such interest is enforceable under applicable law) upon the overdue installments of accrued and unpaid interest at the rate borne by the Notes, plus 1%, from the required payment

date and, (ii) in addition thereto, any amounts due the Trustee under Section 7.06. Until such demand by the Trustee, the Issuer may pay the principal of and interest on the Notes to the registered holders, whether or not the Notes are overdue.

     In case the Issuer shall fail forthwith to pay such amounts upon such demand, the Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered to institute any actions or proceedings at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceeding to judgment or final decree, and may enforce any such judgment or final decree against the Issuer or any other obligor on the Notes and collect in the manner provided by law out of the property of the Issuer or any other obligor on the Notes wherever situated the monies adjudged or decreed to be payable.

     In case there shall be pending proceedings for the bankruptcy or for the reorganization of the Issuer or any other obligor on the Notes under any Bankruptcy Law, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the Issuer or such other obligor, the property of the Issuer or such other obligor, or in the case of any other judicial proceedings relative to the Issuer or such other obligor upon the Notes, or to the creditors or property of the Issuer or such other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 6.02, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal and accrued and unpaid interest in respect of the Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and of the Noteholders allowed in such judicial proceedings relative to the Issuer or any other obligor on the Notes, its or their creditors, or its or their property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due the Trustee under Section 7.06, and to take any other action with respect to such claims, including participating as a member of any official committee of creditors, as it reasonably deems necessary or advisable, unless prohibited by law or applicable regulations, and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Noteholders to make such payments to the Trustee, and, in the event that the Trustee shall consent to the making of such payments directly to the Noteholders, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including counsel fees and expenses incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, advances and disbursements out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and other property which the holders of the Notes may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise.

     All rights of action and of asserting claims under this Indenture, or under any of the Notes, may be enforced by the Trustee without the possession of any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or

proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the holders of the Notes.

     In any proceedings brought by the Trustee (and in any proceedings involving the interpretation of any provision of this Indenture to which the Trustee shall be a party), the Trustee shall be held to represent all the holders of the Notes, and it shall not be necessary to make any holders of the Notes parties to any such proceedings.

     Section 6.03. Application of Monies Collected by Trustee. Any monies collected by the Trustee pursuant to this Article 6, shall be applied, in the following order, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the several Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid:

     FIRST: To the payment of all amounts due the Trustee under Section 7.06;

     SECOND: In case the principal of the outstanding Notes shall not have become due and be unpaid, to the payment of accrued and unpaid interest, if any, on the Notes in default in the order of the maturity of the installments of such interest, with interest (to the extent that such interest has been collected by the Trustee) as provided in Section 6.02 upon the overdue installments of interest at the annual rate borne by the Notes plus 1%, such payments to be made ratably to the Persons entitled thereto;

     THIRD: In case the principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment of the whole amount then owing and unpaid upon the Notes for principal and interest, with interest on the overdue principal and (to the extent that such interest has been collected by the Trustee) upon overdue installments of accrued and unpaid interest, as provided in Section 6.02, and in case such monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Notes, then to the payment of such principal and interest without preference or priority of principal over interest, or of interest over principal, or of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate of such principal and accrued and unpaid interest; and

     FOURTH: To the payment of the remainder, if any, to the Issuer or any other Person lawfully entitled thereto.

     Section 6.04. Proceedings by Noteholder. No holder of any Note shall have any right by virtue of or by reference to any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other similar official, or for any other remedy hereunder, except in the case of a default in the payment of principal of, or interest on, the Notes, unless (a) such holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as hereinbefore provided, (b) the holders of at least twenty-five percent (25%) in aggregate principal amount of the Notes then outstanding

shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and shall have offered to the Trustee such reasonable security or indemnity as it may require against the costs, liabilities or expenses to be incurred therein or thereby, (c) the Trustee for sixty (60) calendar days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute any such action, suit or proceeding and (d) no direction inconsistent with such written request shall have been given to the Trustee pursuant to Section 6.07; it being understood and intended, and being expressly covenanted by the taker and holder of every Note with every other taker and holder and the Trustee, that no one or more holders of Notes shall have any right in any manner whatever by virtue of or by reference to any provision of this Indenture to affect, disturb or prejudice the rights of any other holder of Notes, or to obtain or seek to obtain priority over or preference to any other such holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all holders of Notes (except as otherwise provided herein). For the protection and enforcement of this Section 6.04, each and every Noteholder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

     Notwithstanding any other provision of this Indenture and any provision of any Note, the right of any holder of any Note to receive payment of the principal of (including the redemption price or repurchase price upon redemption or repurchase pursuant to Article 3) and accrued interest on such Note, on or after the respective due dates expressed in such Note or in the event of redemption or repurchase, or to institute suit for the enforcement of any such payment on or after such respective dates against the Issuer shall not be impaired or affected without the consent of such holder.

     Anything contained in this Indenture or the Notes to the contrary notwithstanding, the holder of any Note, without the consent of either the Trustee or the holder of any other Note, in its own behalf and for its own benefit, may enforce, and may institute and maintain any proceeding suitable to enforce, its rights of conversion as provided herein.

     Section 6.05. Proceedings by Trustee. In case of an Event of Default, the Trustee may, in its discretion, proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law.

     Section 6.06. Remedies Cumulative and Continuing. All powers and remedies given by this Article 6 to the Trustee or to the Noteholders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the holders of the Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of any holder of any of the Notes to exercise any right or power accruing upon any default or Event of Default occurring and continuing as aforesaid shall impair any such right or power, or shall be construed to be a waiver of any such default or any acquiescence therein, and, subject to the provisions of Section 6.04, every power and remedy given by this Article 6 or by law to the Trustee or to the Noteholders

may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Noteholders.

     Section 6.07. Direction of Proceedings and Waiver of Defaults by Majority of Noteholders. 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 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 Noteholder to the detriment of other Noteholders and (d) the Trustee may decline to take any action that would involve the Trustee in personal liability.

     The holders of 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 hereunder and its consequences except (i) a default in the payment of the principal of, or interest (including Additional Interest, if any) on, the Notes, (ii) a failure by the Issuer to convert any Notes as required by this Indenture, (iii) a default in the payment of the redemption price on the Redemption Date pursuant to Article 3, (iv) a default in the payment of the repurchase price on the Fundamental Change Repurchase Date or the Repurchase Date pursuant to Article 3 or (v) a default in respect of a covenant or provisions hereof which under Article 9 cannot be modified or amended without the consent of the holders of all Notes then outstanding or each Note affected thereby.

     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 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.

     Section 6.08. Notice of Defaults. The Trustee shall, within ninety (90) calendar days after a Responsible Officer of the Trustee has knowledge of the occurrence of a default, mail to all Noteholders, as the names and addresses of such holders appear upon the Note Register, notice of all defaults known to a Responsible Officer, unless such defaults shall have been cured or waived before the giving of such notice; provided that except in the case of default in the payment of the principal of, or interest (including Additional Interest, if any) on, any of the Notes, the Trustee shall be protected in withholding such notice if and so long as a trust committee of directors and/or Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interest of the Noteholders.

     Section 6.09. Undertaking to Pay Costs. All parties to this Indenture agree, and each holder of any Note by its acceptance thereof shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the

filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section 6.09 (to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to any suit instituted by any Noteholder, or group of Noteholders, holding in the aggregate more than ten percent in principal amount of the Notes at the time outstanding determined in accordance with Section 8.04, or to any suit instituted by any Noteholder for the enforcement of the payment of the principal of, or interest on, any Note on or after the due date expressed in such Note or to any suit for the enforcement of the right to convert any Note in accordance with the provisions of Article 13.

ARTICLE 7
The Trustee

     Section 7.01. Duties and Responsibilities of Trustee. The Trustee, prior to the occurrence of an Event of Default and after the curing or waiver of all Events of Default which may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In case an Event of Default has occurred (which has not been cured or waived), the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of its own affairs.

     No provision of this 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 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 Indenture and no implied covenants or obligations shall be read into this Indenture and the Trust Indenture Act against the Trustee; and

     (ii) in the absence of bad faith and willful misconduct on the part of the Trustee, the Trustee may conclusively rely as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but, in the case of any such certificates or opinions which by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture;

     (b) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer or Officers of the Trustee, unless the Trustee was negligent in ascertaining the pertinent facts;

     (c) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the written direction of the holders of not less than a majority in principal amount of the Notes at the time outstanding determined as provided in Section 8.04 relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture;

     (d) whether or not therein provided, every provision of this Indenture relating to the conduct or affecting the liability of, or affording protection to, the Trustee shall be subject to the provisions of this Section;

     (e) the Trustee shall not be liable in respect of any payment (as to the correctness of amount, entitlement to receive or any other matters relating to payment) or notice effected by the Issuer or any Paying Agent (other than the Trustee) or any records maintained by any co-registrar (other than the Trustee) with respect to the Notes;

     (f) if any party fails to deliver a notice relating to an event the fact of which, pursuant to this 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.

     None of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers, if there is reasonable ground for believing that the repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

     Section 7.02. Reliance on Documents, Opinions, etc. Except as otherwise provided in Section 7.01:

     (a) the Trustee may conclusively rely and shall be protected in acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, debenture, note, coupon or other paper or document (whether in its original or facsimile form) believed by it in good faith to be genuine and to have been signed or presented by the proper party or parties;

     Section 7.04. Trustee, Paying Agents, Conversion Agents, Bid Solicitation Agent or Note Registrar May Own Notes. The Trustee, any Paying Agent, the Conversion Agent, the Bid Solicitation Agent, or Note Registrar, in its individual or any other capacity, may become the owner or pledgee of Notes with the same rights it would have if it were not Trustee, Paying Agent, Conversion Agent, Bid Solicitation Agent or Note Registrar.

     Section 7.05. Monies to be Held in Trust. Subject to the provisions of Section 11.02, all monies received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received.

     Section 7.06. Compensation and Expenses of Trustee. The Issuer covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, such compensation for all services rendered by it hereunder in any capacity (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) as mutually agreed to from time to time in writing between the Issuer and the Trustee, and the Issuer will pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances reasonably incurred or made by the Trustee in accordance with any of the provisions of this Indenture (including the reasonable compensation and the reasonable expenses and disbursements of its counsel and of all Persons not regularly in its employ) except any such expense, disbursement or advance as may arise from its negligence, willful misconduct, recklessness or bad faith. The Issuer also covenants to indemnify the Trustee and any predecessor Trustee (or any officer, director or employee of the Trustee), in any capacity under this Indenture and any authenticating agent for, and to hold them harmless against, any and all loss, liability, damage, claim or reasonable expense including taxes (other than taxes based on the income of the Trustee) incurred without negligence, willful misconduct, recklessness or bad faith on the part of the Trustee or such officers, directors, employees or authenticating agent, as the case may be, and arising out of or in connection with the acceptance or administration of this trust or in any other capacity hereunder, including the reasonable costs and expenses of defending themselves against any claim (whether asserted by the Issuer, any holder or any other Person) of liability in the premises. 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.

     When the Trustee and its agents and any authenticating agent incur expenses or render services after an Event of Default specified in Section 6.01(h), 6.01(i) or 6.01(j) with respect to the Issuer occurs, the expenses and the compensation for the services are intended to constitute reasonable expenses of administration under any bankruptcy, insolvency or similar laws.

     Section 7.07. Officers’ Certificate as Evidence. Except as otherwise provided in Section 7.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or omitting any

action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of gross negligence, bad faith, recklessness or willful misconduct on the part of the Trustee, be deemed to be conclusively proved and established by an Officers’ Certificate delivered to the Trustee.

     Section 7.08. Conflicting Interests of Trustee. If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture.

     Section 7.09. Eligibility of Trustee. There shall at all times be a Trustee hereunder which shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has a combined capital and surplus of at least $50.0 million (or if such Person is a member of a bank holding company system, its bank holding company shall have a combined capital and surplus of at least $50.0 million). If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of any supervising or examining authority, then for the purposes of this Section the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 7.09, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.

Section 7.10. Resignation or Removal of Trustee.

     (a) Subject to Section 7.10(c), the Trustee may at any time resign by giving written notice of such resignation to the Issuer and to the holders of Notes. Upon receiving such notice of resignation, the Issuer shall promptly appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have accepted appointment sixty (60) calendar days after the mailing of such notice of resignation to the Noteholders, the resigning Trustee may, upon ten Business Days’ notice to the Issuer and the Noteholders, petition, at the expense of the Issuer, any court of competent jurisdiction for the appointment of a successor 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:

     (i) the Trustee shall fail to comply with Section 7.08 after written request therefor by the Issuer or by any Noteholder who has been a bona fide holder of a Note or Notes for at least six months; or

     (ii) the Trustee shall cease to be eligible in accordance with the provisions of Section 7.09 and shall fail to resign after written request therefor by the Issuer or by any such Noteholder; or

     (iii) the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or

any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation;

then, in any such case, the Issuer may remove the Trustee and appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of Section 6.09, any Noteholder who has been a bona fide holder of a Note or Notes for at least six months may, on behalf of itself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee.

     (c) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section 7.10 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 7.11.

     (d) Notwithstanding the replacement of the Trustee pursuant to this Section, the Issuer’s obligations under Section 7.06 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 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, 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.

     No successor trustee shall accept appointment as provided in this Section 7.11 unless, at the time of such acceptance, such successor trustee shall be qualified under the provisions of Section 7.08 and be eligible under the provisions of Section 7.09.

     Upon acceptance of appointment by a successor trustee as provided in this Section 7.11, the Issuer (or the former trustee, at the written direction of the Issuer) shall mail or cause to be mailed notice of the succession of such trustee hereunder to the holders of Notes at their addresses as they shall appear on the Note Register. If the Issuer fails to mail such notice within ten (10) calendar days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Issuer.

     Section 7.12. Succession by Merger. Any corporation into which the Trustee may be merged or exchanged or with which it may be consolidated, or any corporation resulting from any merger, exchange or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee (including any trust created by this Indenture), shall be the successor to the Trustee hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that in the case of any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, such corporation shall be qualified under the provisions of Section 7.08 and eligible under the provisions of Section 7.09.

     In case at the time such successor to the Trustee shall succeed to the trusts created by this 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 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).

ARTICLE 8
The Noteholders

     Section 8.01. Action by Noteholders. Whenever in this 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 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, 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, any Conversion 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, and interest on, such Note, for conversion of such Note and for all other purposes; and neither the Issuer nor the Trustee nor any Paying Agent nor any Conversion Agent nor any Note Registrar shall be affected by any notice to the contrary. All such payments so made to any holder for the time being, or upon its order, shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for monies payable upon any such Note.

     Section 8.04. Issuer-Owned Notes Disregarded. In determining whether the holders of the requisite aggregate principal amount of Notes have concurred in any direction, consent, waiver or other action under this Indenture, Notes which are owned by the Issuer or any other obligor on the Notes or any Affiliate of the Issuer or any other obligor on the Notes shall be disregarded and deemed not to be outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, consent, waiver or other action, only Notes which a Responsible Officer knows are so owned shall be so disregarded. 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, 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.

     Section 8.05. Revocation of Consents; Future Holders Bound. At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 8.01, of the taking of any action by the holders of the percentage in aggregate principal amount of the Notes specified in this Indenture in connection with such action, any holder of a Note which is shown by the evidence to be included in the Notes the holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided in Section 8.02, revoke such action so far as concerns such Note. 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.

ARTICLE 9

     (i) to add or modify any provision with respect to matters or questions arising under this Indenture which the Issuer and the Trustee may deem necessary or desirable and which will not adversely affect the interests of the holders of the Notes in any material respect; or

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 this Indenture or otherwise.

     Any supplemental indenture authorized by the provisions of this Section 9.01 may be executed by the Issuer and the Trustee without the consent of the holders of any of the Notes at the time outstanding, notwithstanding any of the provisions of Section 9.02.

     Section 9.02. Supplemental Indenture With Consent of Noteholders.

     Upon the written request of the Issuer, accompanied by a copy of the resolutions of the Board of Directors certified by the Issuer’s Secretary or Assistant Secretary authorizing the execution of any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent of Noteholders as aforesaid, the Trustee shall join with the Issuer in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture.

     It shall not be necessary for the consent of the Noteholders under this Section 9.02 to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such consent shall approve the substance thereof.

     Section 9.03. Effect of Supplemental Indenture. Any supplemental indenture executed pursuant to the provisions of this Article 9 shall comply with the Trust Indenture Act, as then in effect, provided that this Section 9.03 shall not require such supplemental indenture or the Trustee to be qualified under the Trust Indenture Act prior to the time, if ever, such qualification is in fact required under the terms of the Trust Indenture Act or the Indenture has been qualified under the Trust Indenture Act, nor shall it constitute any admission or acknowledgment by any party to such supplemental indenture that any such qualification is required prior to the time, if ever, such qualification is in fact required under the terms of the Trust Indenture Act or the Indenture has been qualified under the Trust Indenture Act. Upon the execution of any supplemental indenture pursuant to the provisions of this Article 9, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitation of rights, obligations, duties and immunities under this Indenture of the Trustee, the Issuer and the holders of Notes shall thereafter be determined, exercised and enforced hereunder, subject in all respects to such modifications and amendments and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes.

     Section 10.02. Issuer Successor to be Substituted.

Such successor Person thereupon may cause to be signed, and may issue either in its own name or in the name of the Issuer any or all of the Notes, issuable hereunder that theretofore shall not have been signed by the Issuer and delivered to the Trustee; and, upon the order of such successor Person instead of the Issuer and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Notes that previously shall have been signed and delivered by the officers of the Issuer to the Trustee for authentication, and any Notes that such successor Person thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under this Indenture as the Notes theretofore or thereafter issued in accordance with the terms of this

Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of any such consolidation, merger, sale, conveyance, transfer or lease, upon compliance with this Article 10 the Person named as the “Issuer” in the first paragraph of this Indenture or any successor that shall thereafter have become such in the manner prescribed in this Article 10 may be dissolved, wound up and liquidated at any time thereafter and such Person shall be discharged from its liabilities as obligor and maker of the Notes and from its obligations under this Indenture and under the Registration Rights Agreement.

     In case of any such consolidation, sale, lease, conveyance or merger, such changes in phraseology and form (but not in substance) may be made in the Notes thereafter to be issued as may be appropriate.

     Section 11.01. Discharge of Indenture. This Indenture shall cease to be of further effect (except as to any surviving rights of conversion, registration of transfer or exchange of Notes herein expressly provided for and except as further provided below), and the Trustee, on demand of and at the expense of the Issuer, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when (a) either: (1) all Notes theretofore authenticated and delivered (other than (i) Notes which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 11.04 and (ii) Notes for whose payment money has theretofore been deposited in trust and thereafter repaid to the Issuer as provided in Section 11.04) have been delivered to the Trustee for cancellation; or (2) all such Notes not theretofore delivered to the Trustee for cancellation have become due and payable, whether upon the Maturity Date, a Redemption Date, a Repurchase Date or a Fundamental Change Repurchase Date or otherwise, or have all been converted in accordance with the provisions of Article 13 hereof, and the Issuer has irrevocably deposited or caused to be irrevocably deposited with the Trustee a Paying Agent or the Conversion Agent (other than the Issuer or any of its Affiliates), as applicable, as trust funds in trust cash and, if applicable, shares of Common Stock in an amount sufficient to pay and discharge the entire indebtedness on such Notes not theretofore delivered to the Trustee for cancellation, for principal and interest to the date of such deposit (in the case of Notes which have become due and payable) or for amounts owing upon conversion; provided, however, that there shall not exist, on the date of such deposit, a default or Event of Default; provided, further, that such deposit shall not result in a breach or violation of, or constitute a default under, this Indenture or any other agreement or instrument to which the Issuer is a party or to which the Issuer is bound; (b) the Issuer has paid or caused to be paid all other sums payable hereunder by the Issuer; and (c) the Issuer has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with.

     Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Issuer to the Trustee under Section 7.06 shall survive and, if money shall have been deposited with the Trustee pursuant to subclause (2) of clause (a) of this Section, the provisions of Sections 2.05, 2.06, 2.07, 3.05, 3.06, 5.01, Article 13 and this Article 11, shall survive until the Notes have been paid in full.

     Section 11.02. Deposited Monies to be Held in Trust by Trustee. Subject to Section 11.04, all monies deposited with the Trustee pursuant to Section 7.05, shall be held in trust for the sole benefit of the Noteholders, and such monies shall be applied by the Trustee to the payment, either directly or through any Paying Agent (including the Issuer if acting as its own Paying Agent), to the holders of the particular Notes for the payment or redemption of which such monies have been deposited with the Trustee, of all sums due and to become due thereon for principal, premium, if any, and interest. All moneys deposited with the Trustee pursuant to Section 7.05 (and held by it or any Paying Agent) for the payment of Notes subsequently converted shall be returned to the Issuer upon request. The Trustee is not responsible to anyone for interest on any deposited funds except as agreed in writing.

     Section 11.03. Paying Agent to Repay Monies Held. Subject to the provisions of Section 11.04, the Trustee or a Paying Agent shall hold in trust, for the benefit of the Noteholders, all money deposited with it pursuant to Section 11.01 and shall apply the deposited money in accordance with this Indenture and the Notes to the payment of the principal of and interest on the Notes.

     Section 11.04. Return of Unclaimed Monies. The Trustee and each Paying Agent shall pay to the Issuer upon request any money held by them for the payment of principal or interest that remains unclaimed for two years after a right to such money has matured; provided, however, that the Trustee or such Paying Agent, before being required to make any such payment, may, at the expense of the Issuer, either publish in a newspaper of general circulation in The City of New York, or cause to be mailed to each Holder entitled to such money, notice that such money remains unclaimed and that after a date specified therein, which shall be at least thirty (30) calendar days from the date of such mailing or publication, any unclaimed balance of such money then remaining will be repaid to the Issuer. After payment to the Issuer, Holders entitled to money must look to the Issuer for payment as general creditors unless an applicable abandoned property law designates another person, and the Trustee and each Paying Agent shall be relieved of all liability with respect to such money.

     Section 11.05. Reinstatement. If the Trustee or the Paying Agent is unable to apply any money in accordance with Section 11.02 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Issuer’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01 until such time as the Trustee or the Paying Agent is permitted to apply all such money in accordance with Section 11.02; provided that if the Issuer makes any payment of principal of or premium, if any, or interest on any Note following the reinstatement of its obligations, the Issuer shall 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.

ARTICLE 12
Immunity of Incorporators, Stockholders, Officers and Directors

     Section 12.01. Indenture and Notes Solely Corporate Obligations. No recourse for the payment of the principal of, or interest on, any Note, or for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement of the Issuer in this Indenture or in any supplemental indenture or in any Note, or because of the

creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, partner, member, manager, employee, agent, officer, director or subsidiary, as such, past, present or future, of the Issuer or any of the Issuer’s Subsidiaries or of any successor thereto, either directly or through the Issuer or any of the Issuer’s Subsidiaries or any successor thereto, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly understood that all such liability is hereby expressly waived and released as a condition of, and as a consideration for, the execution of this Indenture and the issue of the Notes.

ARTICLE 13
Conversion of Notes

     Section 13.01. Right to Convert.

     (a) Subject to the restrictions on ownership of shares of Common Stock as set forth in Section 13.15 and upon compliance with the provisions of this Indenture, the holder of any Notes may convert its Notes, or any portion thereof which is a multiple of $1,000, into cash or, as provided herein, cash and Common Stock, with an aggregate value equal to the Conversion Value, by surrender of such Notes so to be converted in whole or in part, together with any required funds, under the circumstances and in the manner described in this Article 13. Holders may surrender any Notes for conversion not previously redeemed or repurchased (1) prior to the close of business on the second Business Day immediately preceding the Maturity Date at any time on or after December 15, 2030 and (2) prior to December 15, 2030, only upon occurrence of one of the events set forth in clauses (i) through (v) below.

     (i) Conversion Upon Satisfaction of Market Price Condition. A holder may surrender any of its Notes for conversion during any calendar quarter beginning after March 31, 2006 if the Closing Sale Price of the Common Stock for at least twenty (20) Trading Days (whether or not consecutive) in the period of thirty (30) consecutive Trading Days ending on the last Trading Day of the preceding calendar quarter is more than 130% of the Conversion Price per share of Common Stock in effect on the applicable Trading Day. The Board of Directors will make appropriate adjustments, in its good faith determination, to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the ex-dividend date of the event occurs, during that thirty (30) consecutive Trading Day period.

     The Conversion Agent shall, on behalf of the Issuer, determine on a daily basis during the time period specified in this Section 13.01(a)(i) whether the Notes shall be convertible as a result of the occurrence of an event specified in this clause (i) and, if the Notes shall be so convertible, the Conversion Agent shall promptly deliver to the Issuer and the Trustee (if the Trustee is not the Conversion Agent) written notice thereof.

     (ii) Conversion Upon Satisfaction of Trading Price Condition. A holder may surrender any of its Notes for conversion during the five (5) consecutive Trading Day period following any twenty (20) consecutive Trading Day period (the “measurement period”) in which the Trading Price per $1,000 principal amount of Notes (as determined

following a reasonable request by a holder of the Notes) on each Trading Day of such measurement period was less than 95% of the product of the Closing Sale Price of the Common Stock multiplied by the Conversion Rate in effect on the applicable Trading Day.

     ”Trading Price” means, with respect to a Note on any date of determination, the average of the secondary market bid quotations per $1,000 principal amount of Notes obtained by the Bid Solicitation Agent for $5.0 million principal amount of Notes at approximately 3:30 p.m., New York City time, on such determination date from two independent nationally recognized securities dealers selected by the Issuer, which may include the Initial Purchasers; provided that if at least two such bids cannot reasonably be obtained by the Bid Solicitation Agent, but one such bid can reasonably be obtained by the Bid Solicitation Agent, then one bid shall be used; provided, further, that if the Bid Solicitation Agent cannot reasonably obtain at least one bid for $5.0 million principal amount of Notes from a nationally recognized securities dealer or, in the reasonable judgment of the Issuer, the bid quotations are not indicative of the secondary market value of the Notes, then the Trading Price per $1,000 principal amount of Notes will be deemed to be less than 95% of the product of the Closing Sale Price and the Conversion Rate on such determination date.

     The Bid Solicitation Agent shall have no obligation to determine the Trading Price of the Notes unless the Issuer shall have requested such determination, and the Issuer shall have no obligation to make such request unless a holder provides the Issuer with reasonable evidence that the Trading Price per $1,000 principal amount of Notes would be less than 95% of the product of the Closing Sale Price and the applicable Conversion Rate, whereupon the Issuer shall instruct the Bid Solicitation Agent to determine the Trading Price of the Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price is greater than or equal to 95% of the product of the Closing Sale Price and the applicable Conversion Rate.

     (iii) Conversion Upon Notice of Redemption. A holder may surrender for conversion any of the Notes called for redemption at any time prior to 5:00 p.m., New York City time, on the second Trading Day immediately preceding the Redemption Date. The right to convert Notes pursuant to this clause (iii) shall expire after 5:00 p.m., New York City time, on the second Trading Day immediately preceding the Redemption Date unless the Issuer defaults in making the payment due upon redemption.

     (iv) Conversion Upon Specified Corporate Transactions. If the Issuer elects to: (1) distribute to all holders of Common Stock rights entitling them to purchase, for a period expiring within sixty (60) calendar days after the date fixed for determination of stockholders entitled to receive such rights, shares of Common Stock at less than the Closing Sale Price per share of Common Stock on the Trading Day immediately preceding the declaration date of such distribution; or (2) distribute to all holders of Common Stock assets, debt securities or rights to purchase securities of the Issuer, which distribution has a per share value exceeding 10% of the Closing Sale Price per share of Common Stock on the Trading Day immediately preceding the declaration date of such distribution, the Issuer must notify holders of Notes at least twenty (20) calendar days

prior to the ex-dividend date for such distribution. Following the issuance of such notice, holders may surrender their Notes for conversion at any time until the earlier of the close of business on the Business Day prior to the ex-dividend date and an announcement by the Issuer that such distribution will not take place; provided, however, that a holder may not convert its Notes pursuant to this Section 13.01(a)(iv) if such holder may participate, on an as-converted basis (assuming for this purpose that the Notes were convertible solely into Common Stock at the applicable Conversion Rate), in the distribution without any conversion of Notes. The “ex-dividend date” means, with respect to any distribution on shares of Common Stock, the first date upon which a sale of shares of Common Stock does not automatically transfer the right to receive the relevant distribution from the seller of shares of Common Stock.

     In addition, if the Issuer is a party to a consolidation, merger, binding share exchange or sale or conveyance of all or substantially all of its properties and assets, in each case pursuant to which all of the shares of Common Stock would be exchanged for cash, securities and/or other property that does not also constitute a Fundamental Change, a holder may surrender its Notes for conversion at any time from and including the date that is fifteen (15) Business Days prior to the anticipated effective time of the transaction up to and including five (5) Business Days after the actual date of such transaction. In such case, then, at the effective time of the transaction, the right to convert a Note into cash and, if applicable, shares of Common Stock will be changed in the manner provided in Section 13.06. The Issuer shall notify holders of Notes as promptly as practicable following the date such transaction is publicly announced (but in no event less than fifteen (15) Business Days prior to the effective time of such transaction).

     (v) Conversion Upon a Fundamental Change. If a Fundamental Change occurs, a holder of Notes may convert its Notes at any time beginning fifteen (15) Business Days prior to the date announced by the Issuer as the anticipated Effective Date of the Fundamental Change up to and including the fifth Business Day following the Effective Date of the Fundamental Change. The Issuer shall notify holders of the Notes of the anticipated Effective Date of the Fundamental Change as promptly as practicable following the date on which it publicly announces a Fundamental Change (but in no event less than twenty (20) Business Days prior to the anticipated Effective Date of the Fundamental Change).

     (b) Whenever the Notes shall become convertible pursuant to this Section 13.01, the Issuer or, at the Issuer’s request, the Trustee in the name and at the expense of the Issuer, shall notify the holders of the event triggering such convertibility in the manner provided in Section 15.03, and the Issuer shall also publicly announce such information and publish it on its web site. Any notice so given shall be conclusively presumed to have been duly given, whether or not the holder receives such notice.

     (c) A Note in respect of which a holder has delivered a Repurchase Notice exercising such holder’s right to require the Issuer to repurchase such Note pursuant to Section 3.05 or 3.06 may be converted only if such Repurchase Notice is withdrawn in accordance with Section 3.07 prior to the close of business on the Repurchase Date or the Fundamental Change Repurchase Date, as applicable.

     (d) A holder of Notes is not entitled to any rights of a holder of Common Stock until such holder has converted its Notes and received upon conversion thereof shares of Common Stock. The person in whose name any certificate or certificates for shares of Common Stock shall be issuable upon such conversion, if any, shall become on the date any such certificate or certificates are delivered to such holder in accordance with the provisions of this Article 13, the holder of record of the shares represented thereby.

     Section 13.02. Exercise of Conversion Right; No Adjustment for Interest or Dividends. In order to exercise the conversion right with respect to any Note in certificated form, the Issuer must receive at the office or agency of the Issuer maintained for that purpose in The City of New York or, at the option of such holder, the Corporate Trust Office, such Note with the original or facsimile of the form entitled “Conversion Notice” on the reverse thereof, duly completed and manually signed, together with such Notes duly endorsed for transfer, accompanied by the funds, if any, required by this Section 13.02. Such notice shall also state the name or names (with address or addresses) in which the certificate or certificates for shares of Common Stock, if any, which shall be issuable on such conversion shall be issued (if other than in the name of the holder tendering such Note for conversion), and shall be accompanied by transfer or similar taxes, if required pursuant to Section 13.07.

     In order to exercise the conversion right with respect to any interest in a Global Note, the beneficial holder must complete, or cause to be completed, the appropriate instruction form for conversion pursuant to the Depositary’s book-entry conversion program; deliver, or cause to be delivered, by book-entry delivery such interest in such Global Note; furnish appropriate endorsements and transfer documents if required by the Issuer or the Trustee or the Conversion Agent; and pay the funds, if any, required by this Section 13.02 and any transfer taxes if required pursuant to Section 13.07.

     Each conversion shall be deemed to have been effected as to any such Note (or portion thereof) on the date on which the requirements set forth above in this Section 13.02 have been satisfied as to such Note (or portion thereof) (the “Conversion Date”).

     Except as set forth in the next succeeding paragraph, upon conversion of a Note, a holder shall not be entitled to receive any cash payment in respect of interest, and the Issuer shall not be required to adjust the Conversion Rate to account for any accrued and unpaid interest (including Additional Interest, if any). The delivery by the Issuer to the holder of cash and Common Stock, if any, upon conversion shall be deemed to satisfy the Issuer’s obligation with respect to Notes tendered for conversion. Accordingly, upon conversion of Notes, any accrued but unpaid interest shall be deemed to be paid in full, rather than cancelled, extinguished or forfeited.

     Holders of Notes at the close of business on a Record Date for an interest payment shall receive payment of the interest payable on the corresponding Interest Payment Date notwithstanding the conversion of such Notes at any time after the close of business on the applicable Record Date and prior to the corresponding Interest Payment Date. Accordingly, any Note or portion thereof surrendered for conversion after the close of business on the Record Date for any Interest Payment Date and prior to the corresponding Interest Payment Date shall be accompanied by payment, in immediately available funds or other funds acceptable to the Issuer, of an amount equal to the interest otherwise payable on such Interest Payment Date on the

principal amount being converted; provided that no such payment need be made (1) if a holder converts its Notes in connection with a redemption and the Issuer has specified a Redemption Date that is after a Record Date and on or prior to the corresponding Interest Payment Date, (2) if a holder converts its Notes in connection with a Fundamental Change and the Issuer has specified a Fundamental Change Repurchase Date that is after a Record Date and on or prior to the corresponding Interest Payment Date or (3) to the extent of any overdue interest and Additional Interest, if any overdue interest and Additional Interest, as applicable, exists at the time of conversion with respect to such Notes. Except as otherwise provided above in this Article 13, no payment or other adjustment shall be made for interest accrued on any Note converted or for dividends on any shares issued upon the conversion of such Note as provided in this Article 13.

     In case any Note of a denomination greater than $1,000 shall be surrendered for partial conversion, and subject to Section 2.04, the Issuer shall execute and the Trustee shall authenticate and deliver to the holder of the Note so surrendered, without charge to the holder, a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note.

     Upon the conversion of an interest in a Global Note, the Trustee (or other Conversion Agent appointed by the Issuer), or the Custodian at the direction of the Trustee (or other Conversion Agent appointed by the Issuer), shall make a notation on such Global Note as to the reduction in the principal amount represented thereby. The Issuer shall notify the Trustee in writing of any conversion of Notes effected through any Conversion Agent other than the Trustee.

     Section 13.03. Cash Payments in Lieu of Fractional Shares. No fractional shares of Common Stock or scrip certificates representing fractional shares shall be issued upon conversion of Notes. If more than one Note shall be surrendered for conversion at one time by the same holder, the number of full shares that shall be issuable upon conversion shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted hereby) so surrendered. If any fractional share of stock would be issuable upon the conversion of any Note or Notes, the Issuer shall make an adjustment and payment therefor in cash to the holder of Notes at a price equal to the Twenty Day Weighted Average Price applicable to such conversion.

     Section 13.04. Conversion Rate. The Conversion Rate for the Notes is 35.2988 shares of Common Stock per each $1,000 principal amount of the Notes (herein called the “Conversion Rate”), subject to adjustment as provided in Sections 13.05 and 13.13.

     Section 13.05. Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Issuer as follows:

     (a) In case the Issuer shall hereafter pay a dividend or make a distribution to all or substantially all holders of the outstanding Common Stock in shares of Common Stock, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect at the opening of business on the date following the

date fixed for the determination of stockholders entitled to receive such dividend or other distribution by a fraction,

     (i) the numerator of which shall be the sum of the number of shares of Common Stock outstanding at the close of business on the date fixed for the determination of stockholders entitled to receive such dividend or other distribution plus the total number of shares of Common Stock constituting such dividend or other distribution; and

     (ii) the denominator of which shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination,

such increase to become effective immediately after the opening of business on the day following the date fixed for such determination. For the purpose of this paragraph (a), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Issuer. The Issuer will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Issuer. If any dividend or distribution of the type described in this Section 13.05(a) is declared but not so paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

     (b) In case outstanding shares of Common Stock shall be subdivided or split into a greater number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately increased, and conversely, in case outstanding shares of Common Stock shall be combined into a smaller number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately reduced, such increase or reduction, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective.

     (c) In case the Issuer shall issue rights or warrants to all or substantially all holders of its outstanding shares of Common Stock entitling them (for a period expiring within sixty (60) calendar days after the date fixed for determination of stockholders entitled to receive such rights or warrants) to subscribe for or purchase shares of Common Stock or securities convertible into or exchangeable or exercisable for Common Stock at a price per share (or having an exercise, conversion or exchange price) less than the Closing Sale Price of the Common Stock on the Business Day immediately preceding the date of announcement of such issuance of such rights or warrants, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the date fixed for determination of stockholders entitled to receive such rights or warrants by a fraction,

     (i) the numerator of which shall be the number of shares of Common Stock outstanding on the date fixed for determination of stockholders entitled to receive such rights or warrants plus the total number of additional shares of Common Stock offered (or underlying such convertible, exchangeable or exercisable securities offered) for subscription or purchase, and

     (ii) the denominator of which shall be the sum of the number of shares of Common Stock outstanding at the close of business on the date fixed for determination of stockholders entitled to receive such rights or warrants plus the number of shares of Common Stock (or convertible, exchangeable or exercisable securities) that the aggregate offering price of the total number of shares (or convertible, exchangeable or exercisable securities) so offered for subscription or purchase (or the aggregate conversion, exchange or exercise price) would purchase at the Current Market Price on such date.

     Such adjustment shall be successively made whenever any such rights or warrants are issued, and shall become effective immediately after the opening of business on the day following the date fixed for determination of stockholders entitled to receive such rights or warrants. To the extent that shares of Common Stock are not delivered after the expiration of such rights or warrants, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights or warrants are not so issued, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such date fixed for the determination of stockholders entitled to receive such rights or warrants had not been fixed. In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such Current Market Price, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Issuer for such rights or warrants and any amount payable on exercise or exchange thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors.

     (d) In case the Issuer shall, by dividend or otherwise, distribute to all or substantially all holders of Common Stock shares of any class of capital stock of the Issuer or evidences of its indebtedness or assets (including securities, but excluding (i) any dividends, distributions, rights, warrants, options, other securities or convertible securities referred to in Sections 13.01(a) or 13.05(c), (ii) any dividends and distributions in connection with a reclassification, change, consolidation, merger, binding share exchange, sale, transfer, lease, conveyance or other disposition to which Section 13.06 applies or (iii) dividends or distributions paid exclusively in cash) (any of the foregoing hereinafter in this Section 13.05(d) called the “Securities”), then, in each such case, the Conversion Rate shall be increased so that the same shall be equal to the rate determined by multiplying the Conversion Rate in effect on the record date with respect to such distribution by a fraction,

     (i) the numerator of which shall be the Current Market Price on such record date; and

     (ii) the denominator of which shall be the Current Market Price on such record date less the Fair Market Value (as determined by the Board of Directors, whose determination shall be conclusive, and described in a resolution of the Board of Directors) on the record date of the portion of the Securities so distributed applicable to one share of Common Stock,

such adjustment to become effective immediately prior to the opening of business on the day following such record date; provided that if the then Fair Market Value (as so determined) of the portion of the Securities so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price on the record date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Noteholder shall have the right to receive upon conversion the amount of Securities such holder would have received had such Noteholder held a number of Shares of Common Stock equal to Conversion Rate in effect on the record date. If such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. If the Board of Directors determines the Fair Market Value of any distribution for purposes of this Section 13.05(d) by reference to the actual or when issued trading market for any securities, it must in doing so consider the prices in such market over the same period used in computing the Current Market Price on the applicable record date.

     If the dividend or distribution requiring an adjustment pursuant to this Section 13.05(d) consists of capital stock of any class or series, or similar equity interests, of a Subsidiary or other business unit of the Issuer, for purposes of making such adjustment, (i) the Current Market Price shall be based on the average of the Closing Sale Prices of such securities for the ten Trading Days commencing on and including the fifth Trading Day after the date on which “ex-dividend trading” commences for such distribution on The New York Stock Exchange or such other national or regional exchange or market on which such securities are then listed or quoted, and (ii) the Fair Market Value of such securities shall be determined as provided herein, measured for the same period.

     Rights or warrants distributed by the Issuer to all or substantially all holders of Common Stock entitling the holders thereof to subscribe for or purchase shares of the Issuer’s capital stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 13.05 (and no adjustment to the Conversion Rate under this Section 13.05 will be required) until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 13.05(d). If any such right or warrant, including any such existing rights or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and record date with respect to new rights or warrants with such rights (and a termination or expiration of the existing rights or warrants without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 13.05 was made, (1) in the case of any such rights or warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Rate shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash

distribution, equal to the per share redemption or repurchase price received by a holder or holders of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights and warrants had not been issued.

     No adjustment of the Conversion Rate shall be made pursuant to this Section 13.05(d) in respect of rights or warrants distributed or deemed distributed on any Trigger Event to the extent that such rights or warrants are actually distributed, or reserved by the Issuer for distribution to holders of Notes (in an amount per Note equal to the number of such rights or warrants that shall have been distributed in respect of a number of shares of Common Stock equal to the Conversion Rate in effect at the times of such Trigger Event) upon conversion by such holders of Notes in accordance with this Article 13.

     For purposes of this Section 13.05(d) and Section 13.05(a) and (c), any dividend or distribution to which this Section 13.05(d) is applicable that also includes shares of Common Stock, or rights or warrants to subscribe for or purchase shares of Common Stock (to which the provisions of Section 13.05(a) or 13.05(c) or both would apply), shall be deemed instead to be (1) a dividend or distribution of the Securities other than such shares of Common Stock or rights or warrants (and any Conversion Rate adjustment required by this Section 13.05(d) with respect to such dividend or distribution shall then be made) immediately followed by (2) a dividend or distribution of such shares of Common Stock or such rights or warrants (and any further Conversion Rate adjustment required by Sections 13.05(a) and 13.05(c) with respect to such dividend or distribution shall then be made), except (A) the record date of such dividend or distribution shall be substituted as “the date fixed for the determination of stockholders entitled to receive such dividend or other distribution”, “the date fixed for the determination of stockholders entitled to receive such rights or warrants” and “the date fixed for such determination” within the meaning of Section 13.05(a) and 13.05(c), respectively, and (B) any shares of Common Stock included in such dividend or distribution shall not be deemed “outstanding at the close of business on the date fixed for such determination” within the meaning of Section 13.05(a).

     (e) In case the Issuer shall, by dividend or otherwise, distribute to all or substantially all holders of its Common Stock cash (excluding (x) any dividend or distribution in connection with the liquidation, dissolution or winding up of the Issuer, whether voluntary or involuntary, (y) any cash dividend distributed on the Common Stock to the extent the aggregate of all cash dividends per share of Common Stock in any Fiscal Quarter does not exceed $0.30 (the “dividend threshold amount”) and (z) any dividend or distribution in connection with a reclassification, change, consolidation, merger, binding share exchange, sale, transfer, lease, conveyance or other disposition to which Section 13.06 applies), then, in such case, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect on the applicable record date by a fraction,

     (i) the numerator of which shall be the Current Market Price on such record date minus the dividend threshold amount; and

     (ii) the denominator of which shall be the Current Market Price on such record date minus the full amount of cash distributed in the applicable Fiscal Quarter in respect of one share of Common Stock,

such adjustment to be effective immediately prior to the opening of business on the day following the record date. If such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

     The “dividend threshold amount” shall be subject to adjustment as of any date on which the Conversion Rate of the Notes is adjusted pursuant to this Section 13.05 (other than on account of any adjustment to the Conversion Rate as a result of the provisions set forth in this Section 13.05(e)). The dividend threshold amount, as adjusted, will equal the dividend threshold amount immediately prior to such adjustment, multiplied by a fraction, (i) the numerator of which is the Conversion Rate immediately prior to the adjustment giving rise to the dividend threshold amount adjustment and (ii) the denominator of which is the Conversion Rate as so adjusted.

     (f) In case a tender or exchange offer made by the Issuer or any Subsidiary of the Issuer for all or any portion of the Common Stock shall expire and such tender or exchange offer (as amended upon the expiration thereof) shall require the payment to stockholders of consideration per share of Common Stock having a fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a resolution of the Board of Directors) that as of the last time (the “Expiration Time”) tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended) exceeds the Current Market Price (which, for purposes of this Section 13.05(f), shall mean the average of the Closing Sale Prices of the Common Stock for the ten consecutive Trading Days ending on the Trading Day immediately prior to the Expiration Time), the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the Expiration Time by a fraction,

     (i) the numerator of which shall be the sum of (x) the fair market value (determined as aforesaid) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of all shares validly tendered or exchanged and not withdrawn as of the Expiration Time (the shares deemed so accepted up to any such maximum, being referred to as the “Purchased Shares”) and (y) the product of the number of shares of Common Stock outstanding (less any Purchased Shares) at the Expiration Time and the Current Market Price immediately prior to the Expiration Time, and

     (ii) the denominator of which shall be the number of shares of Common Stock outstanding (including any tendered or exchanged shares) at the Expiration Time multiplied by the Current Market Price immediately prior to the Expiration Time,

such adjustment to become effective immediately prior to the opening of business on the day following the Expiration Time. If the Issuer is obligated to purchase shares pursuant to any such tender or exchange offer, but the Issuer is permanently prevented by applicable law from

effecting any such purchases or all such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such tender or exchange offer had not been made.

     (g) For purposes of this Section 13.05, the following terms shall have the meaning indicated:

     (i) “Current Market Price” shall mean the average of the daily Closing Sale Prices per share of Common Stock over the ten consecutive Trading Days ending on the earlier of such date of determination and the day before the “ex” date with respect to the issuance, distribution, subdivision or combination requiring such computation. For purpose of this paragraph, the term “ex” date, (1) when used with respect to any issuance or distribution, means the first date on which the Common Stock trades, regular way, on the relevant exchange or in the relevant market from which the Closing Sale Price was obtained without the right to receive such issuance or distribution, and (2) when used with respect to any subdivision or combination of shares of Common Stock, means the first date on which the Common Stock trades, regular way, on such exchange or in such market after the time at which such subdivision or combination becomes effective.

     If another issuance, distribution, subdivision or combination to which Section 13.05 applies occurs during the period applicable for calculating “Current Market Price” pursuant to the definition in the preceding paragraph, “Current Market Price” shall be calculated for such period in a manner determined by the Board of Directors to reflect the impact of such issuance, distribution, subdivision or combination on the Closing Sale Price of the Common Stock during such period.

     (ii) “Fair Market Value” shall mean the amount which a willing buyer would pay a willing seller in an arm’s-length transaction.

     (iii) “record date” shall mean, with respect to any dividend, distribution or other transaction or event in which the holders of Common Stock have the right to receive any cash, securities or other property or in which the Common Stock (or other applicable security) is exchanged for or exchanged into any combination of cash, securities or other property, the date fixed for determination of stockholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise).

     (h) [Intentionally omitted]

     (i) The Issuer may make such increases in the Conversion Rate, in addition to those required by Section 13.05(a) through (f) as the Board of Directors considers to be advisable to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for income tax purposes.

     To the extent permitted by applicable law, the Issuer from time to time may increase the Conversion Rate by any amount for any period of time if the increase is irrevocable during the period and the Board of Directors shall have made a determination that such increase would be in

the best interests of the Issuer, which determination shall be conclusive. Whenever the Conversion Rate is increased pursuant to the preceding sentence, the Issuer shall mail to holders of record of the Notes at least fifteen (15) calendar days prior to the date increased Conversion Rate takes effect, a notice of the increase, and such notice shall state the increased Conversion Rate and the period during which it will be in effect.

     (j) No adjustment in the Conversion Rate will be made: (a) upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on securities of the Issuer and the investment of additional optional amounts in shares of Common Stock under any plan; (b) upon the issuance of any shares of Common Stock or options or rights to purchase such shares pursuant to any present or future employee, director, or consultant benefit plan or program of the Issuer; (c) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security outstanding as of the date hereof; (d) for a change in the par value or a change to no par value of the Common Stock; or (e) for accrued and unpaid interest (including Additional Interest, if any).

     (k) No adjustment in the Conversion Rate shall be required unless such adjustment would require an increase or decrease of at least one percent (1%) in such rate; provided that any adjustments that by reason of this Section 13.05(k) are not required to be made shall be carried forward and the Issuer shall make such carry forward adjustments, regardless of whether the aggregate adjustment is less than 1%, upon redemption, upon a Fundamental Change or at maturity, as applicable. All calculations under this Article 13 shall be made by the Issuer and shall be made to the nearest cent or to the nearest one-thousandth (1/1,000) of a share, as the case may be. Except as otherwise provided in this Indenture, no adjustment need be made for any issuance of Common Stock or convertible or exchangeable securities or rights to purchase Common Stock or convertible or exchangeable securities. Interest will not accrue on any cash into which the Notes are convertible.

     (l) Whenever the Conversion Rate is adjusted as herein provided, the Issuer shall promptly file with the Trustee and any Conversion Agent other than the Trustee an Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Issuer shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective and shall mail such notice of such adjustment of the Conversion Rate to the holder of each Note at its last address appearing on the Note Register provided for in Section 2.05 of this Indenture, within twenty (20) calendar days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

     (m) [Intentionally Omitted]

     (n) For purposes of this Section 13.05, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Issuer but shall include

shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Issuer will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Issuer.

     (o) If, in connection with any adjustment to the Conversion Rate as set forth in this Section 13.05, a Holder shall be deemed for U.S. federal tax purposes to have received a distribution or an additional interest payment, the Issuer may set off any withholding tax it is required to collect with respect to any such deemed distribution or payment against cash payments of interest in accordance with Section 2.03 or from cash and shares of Common Stock, if any, otherwise deliverable to a Holder upon a conversion of Notes in accordance with the provisions of Section 13.12 hereof or a redemption or repurchase of a Note in accordance with the provisions of Section 3.01, 3.05 or 3.06 hereof.

     (p) No adjustment to the Conversion Rate shall be made pursuant to this Section 13.05 if the holders of the Notes may participate, on an as converted basis (assuming for this purpose that the Notes were convertible solely into Common Stock at the applicable Conversion Rate), in the transaction that would otherwise give rise to adjustment pursuant to this Section 13.05.

     Section 13.06. Change in Conversion Right Upon Certain Reclassifications, Business Combinations and Asset Sales.

     (a) If any of the following shall occur (including as a result of a Fundamental Change), namely: (i) any reclassification or change of outstanding shares of Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination); (ii) any consolidation, merger or binding share exchange to which the Issuer is a party other than a merger in which the Issuer is the resulting or surviving corporation and which does not result in any reclassification of, or change (other than a change in name, or par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination) in, outstanding shares of Common Stock; or (iii) any sale, transfer, lease, conveyance or other disposition of all or substantially all of the properties and assets of the Issuer, in each case, pursuant to which holders of Common Stock would be entitled to receive stock, other securities, other property, assets or cash in exchange for their Common Stock, then the Issuer, or such successor or purchasing corporation, as the case may be, shall, as a condition precedent to such reclassification, change, consolidation, merger, binding share exchange, sale, transfer, lease, conveyance or other disposition, execute and deliver to the Trustee a supplemental indenture providing that the holder of each Note then outstanding shall have the right to convert such Note by reference to the kind and amount of cash, securities or other property that a holder of the number of shares of Common Stock equal to the Conversion Rate of such Note immediately prior to such transaction would have owned or been entitled to receive (the “Reference Property”). Such supplemental indenture shall (a) provide for adjustments of the Conversion Rate which shall be as nearly equivalent as may be practicable to the adjustments of the Conversion Rate provided for in this Article 13, including, without limitation, the provisions of Sections 13.12 and 13.13, (b) provide that from and after the effective time of such transaction, a Noteholder will be entitled thereafter to convert its Notes into cash (up to the aggregate principal amount thereof) and Reference Property (or cash in lieu thereof) based on the Twenty Day Weighted Average Price of the

Reference Property and the applicable Conversion Rate as set forth in Section 13.12 and set forth such other appropriate modifications to the means of determining the Conversion Value and settlement provisions specified in this Article 13 so as to be nearly equivalent to such provisions applicable on the date hereof with respect to the Common Stock as may be practicable and (c) specify the Conversion Rate immediately after such transaction. Notwithstanding the foregoing, a distribution by the Issuer to all or substantially all holders of Common Stock for which an adjustment to the Conversion Rate or provision for conversion of the Notes may be made pursuant to Section 13.05 shall not be deemed to be a sale or conveyance of all or substantially all of the properties and assets of the Issuer for purposes of this Section 13.06.

     (b) In the event the Issuer shall execute a supplemental indenture pursuant to this Section 13.06, the Issuer shall promptly file with the Trustee an Opinion of Counsel stating that such supplemental indenture is authorized or permitted by this Indenture and an Officers’ Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or other property receivable by holders of the Notes upon the conversion of their Notes after any such reclassification, change, consolidation, merger, binding share exchange, sale, transfer, lease or conveyance, any adjustment to be made with respect thereto and that all conditions precedent have been complied with.

     (c) In the event holders of shares of Common Stock have the opportunity to elect the form of consideration to be received in such reclassification, change, consolidation, merger, binding share exchange, sale, transfer, lease, conveyance or other disposition, the Issuer shall make adequate provision whereby the holders of the Notes shall have a reasonable opportunity to determine the form of consideration into which the Notes shall be convertible from and after the effective date of such transaction, in each case, for purposes of all outstanding Notes, treated as a single class.

     (d) If this Section 13.06 applies to any event or occurrence, Section 13.05 shall not apply. The provisions of this Section 13.06 shall similarly apply to successive reclassifications, changes, consolidations, mergers, sales, transfers, leases, conveyances or other dispositions.

     Section 13.07. Taxes on Shares Issued. The issue of stock certificates, if any, on conversion of Notes shall be made without charge to the converting Noteholder for any documentary, stamp or similar issue or transfer tax in respect of the issue thereof. The Issuer shall not, however, be required to pay any such tax which may be payable in respect of any transfer involved in the issue and delivery of stock in any name other than that of the holder of any Note converted, and the Issuer shall not be required to issue or deliver any such stock certificate unless and until the Person or Persons requesting the issue thereof shall have paid to the Issuer the amount of such tax or shall have established to the satisfaction of the Issuer that such tax has been paid.

     Section 13.08. Reservation of Shares, Shares to be Fully Paid; Compliance with Governmental Requirements. The Issuer shall provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for the conversion of the Notes as required by this Indenture from time to time as such Notes are presented for conversion.

     Before taking any action which would cause an adjustment increasing the Conversion Rate to an amount that would cause the Conversion Price to be reduced below the then par value, if any, of the shares of Common Stock issuable, if any, upon conversion of the Notes, the Issuer will take all corporate action which may, in the opinion of its counsel, be necessary in order that the Issuer may validly and legally issue shares of such Common Stock at such adjusted Conversion Rate.

     The Issuer covenants that all shares of Common Stock, if any, which may be issued upon conversion of Notes will upon issue be fully paid and non-assessable and free from all taxes, liens and charges with respect to the issue thereof.

     Section 13.09. Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any holder of Notes to determine the Conversion Rate or whether any facts exist which may require any adjustment of the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any capital stock, other securities or other assets or property, which may at any time be issued or delivered upon the conversion of any Note; and the Trustee and any other Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Issuer to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Issuer contained in this Article 13. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 13.06 relating either to the kind or amount of shares of capital stock or other securities or other assets or property (including cash) receivable by Noteholders upon the conversion of their Notes after any event referred to in such Section 13.06 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.01, may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers’ Certificate (which the Issuer shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. The Trustee shall not at any time be under any duty or responsibility to any holder of Notes to determine the accuracy of the method employed in calculating the Trading Price or whether any facts exist which may require any adjustment of the Trading Price.

     Section 13.10. Notice to Holders Prior to Certain Actions. In case:

     (a) the Issuer shall declare a dividend (or any other distribution) on its Common Stock that would require an adjustment in the Conversion Rate pursuant to Section 13.05; or

     (b) the Issuer shall authorize the granting to the holders of all or substantially all of its Common Stock of rights or warrants to subscribe for or purchase any share of any class or any other rights or warrants; or

     (c) of any reclassification or reorganization of the Common Stock (other than a subdivision or combination of its outstanding Common Stock, or a change in par value, or from par value to no par value, or from no par value to par value), or of any consolidation, combination, merger or share exchange to which the Issuer is a party and for which approval of any stockholders of the Issuer is required, or of the sale or transfer of all or substantially all of the assets of the Issuer; or

     (d) of the voluntary or involuntary dissolution, liquidation or winding up of the Issuer;

the Issuer shall cause to be filed with the Trustee and to be mailed to each holder of Notes at its address appearing on the Note Register provided for in Section 2.05 of this Indenture, as promptly as possible but in any event at least ten (10) calendar days prior to the applicable date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution or rights or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution or rights are to be determined, or (y) the date on which such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such dividend, distribution, reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up.

     Section 13.11. Stockholder Rights Plans. If the rights provided for in the Issuer’s Rights Agreement dated as of September 14, 1999 or in any future rights plan adopted by the Issuer have separated from the shares of Common Stock in accordance with the provisions of the applicable stockholder rights agreement so that the holders of the Notes would not be entitled to receive any rights in respect of Common Stock issuable upon conversion of the Notes, if any, the Conversion Rate will be adjusted as provided in Section 13.05(d). To the extent that the rights under any such rights plan shall not have separated from the Common Stock, holders who convert Notes shall be entitled to receive (to the extent that Common Stock shall be issued upon such conversion) the rights under any such rights plan.

     Section 13.12. Settlement Upon Conversion.

     (a) Upon the tender of Notes for conversion by the holder thereof in accordance with the provisions of this Indenture, the Issuer shall satisfy its obligation upon conversion (the “Conversion Obligation”) by payment and delivery of cash and, if applicable as provided herein, shares of Common Stock, the aggregate value of which (the “Conversion Value”), for each $1,000 aggregate principal amount of Notes so converted, shall be equal to the product of:

     (i) the Conversion Rate in effect on the Conversion Date; and

     (ii) the average of the daily Volume Weighted Average Prices of the Common Stock for each of the twenty (20) consecutive Trading Days (appropriately adjusted to

take into account the occurrence during such period of stock splits and similar events) beginning on the second Trading Day immediately following the day the Notes are tendered for conversion (the “Twenty Day Weighted Average Price”). The “Volume Weighted Average Price” per share of the Common Stock on any Trading Day will be the volume weighted average price on the New York Stock Exchange or, if the Common Stock is not listed on the New York Stock Exchange, on the principal U.S. national or regional securities exchange, the Nasdaq National Market or over-the-counter market on which the Common Stock is then listed or traded, from 9:30 a.m. to 4:00 p.m. (New York City time) on such Trading Day as displayed by Bloomberg (or if such volume weighted average price is not available, the market value of one share on such Trading Day as the Board of Directors determine in good faith using a volume weighted averaging method).

     (b) The Issuer shall deliver the Conversion Value of the Notes surrendered for conversion to converting holders as follows:

     (i) an amount in cash (the “Principal Return”) equal to the lesser of (A) the aggregate Conversion Value of the Notes to be converted and (B) the aggregate principal amount of the Notes to be converted;

     (ii) if the aggregate Conversion Value of the Notes to be converted is greater than the Principal Return, an amount in cash (the “Net Cash Amount”) or, at the election of the Issuer, an amount in whole shares of Common Stock (the “Net Shares Amount”), determined pursuant to Section 13.12(c), or a combination thereof equal to such aggregate Conversion Value less the Principal Return (the “Net Amount”); and

     (iii) an amount in cash in lieu of any fractional shares of Common Stock.

     (c) The Net Cash Amount to be paid shall equal that portion of the Net Amount to be paid in cash. The Net Shares Amount to be paid will be determined by dividing that portion of the Net Amount to be delivered in shares of Common Stock by the Twenty Day Weighted Average Price. The cash payment for fractional shares shall, in accordance with the provisions of Section 13.03, be based on the Twenty Day Weighted Average Price.

     (d) The Conversion Value, Principal Return, Net Amount, Net Cash Amount and Net Shares Amount shall be determined by the Issuer at the end of the twenty (20) consecutive Trading Day period beginning on the second Trading Day immediately following the day the Notes are tendered for conversion (the “Averaging Period”). Prior to the close of business on the Trading Day next following the day on which Notes are tendered for conversion, the Issuer shall notify holders of such Notes of the Issuer’s election to pay cash for all or a portion of the Net Amount and, if applicable, the percentage of the Net Amount that the Issuer shall pay in cash and the percentage of the Net Amount that the Issuer shall pay in shares of Common Stock.

     (e) Payment of the cash and Net Amount, if any, in satisfaction of the Conversion Obligation shall be made by the Issuer as promptly as practicable following the last Trading Day of the Averaging Period, but in no event later than three Business Days thereafter by paying in cash the Principal Return, the Net Cash Amount and any cash in lieu of fractional shares to the holder of a Note surrendered for conversion, or such holder’s nominee or nominees, and issue, or

cause to be issued, and deliver to the Conversion Agent or to such holder, or such holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the number of full shares of Common Stock equal to the Net Shares Amount, if any, to which such holder shall be entitled as part of such Conversion Obligation.

     Section 13.13. Conversion Rate Adjustment After Certain Fundamental Changes.

     (a) Subject to the provisions hereof, if a Noteholder elects to convert its Notes pursuant to Section 13.01(a)(v) following the occurrence of a transaction described in clause (1) or (2) of the definition of Fundamental Change that occurs prior to January 15, 2011, the Issuer shall increase the applicable Conversion Rate for the Notes so surrendered for conversion by the number of additional shares of Common Stock (the “Additional Shares”) specified below. A conversion of Notes will be deemed for these purposes to be “in connection with” such a Fundamental Change, subject to Section 13.14, if the Conversion Notice is received by the Conversion Agent from and including the date that is fifteen (15) Business Days prior to the anticipated Effective Date of the Fundamental Change until and including the fifth Business Day following the Effective Date. The Issuer shall notify holders of the Notes at least twenty (20) Business Days prior to the anticipated Effective Date of the Fundamental Change transaction of such anticipated Effective Date and whether the Issuer elects, if such transaction is also a Public Acquirer Change of Control, to modify the Conversion Obligation in the manner set forth in Section 13.14 in lieu of increasing the Conversion Rate.

     (b) The number of Additional Shares will be determined by reference to the table in Section 13.13(e) and is based on the date on which the Fundamental Change becomes effective (the “Effective Date”) and the price paid per share of the Common Stock in the Fundamental Change transaction (the “Stock Price”). If holders of the Common Stock receive only cash in the Fundamental Change transaction, the Stock Price shall equal the cash amount paid per share of Common Stock in such transaction. In all other cases, the Stock Price shall equal the average of the Closing Sale Prices of the Common Stock over the ten consecutive Trading Days up to but excluding the Effective Date.

     (c) The Stock Prices set forth in the first column of the table set forth in Section 13.13(e) shall be adjusted as of any date on which the Conversion Rate of the Notes is adjusted pursuant to Section 13.05. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, (i) the numerator of which shall be the Conversion Rate immediately prior to the adjustment giving rise to the Stock Price adjustment and (ii) the denominator of which shall be the Conversion Rate as so adjusted.

     (d) The number of Additional Shares shall be adjusted in the same manner and for the same events as the Conversion Rate is adjusted pursuant to Section 13.05.

     (e) The following table sets forth the Stock Price and number of Additional Shares issuable per $1,000 principal amount of Notes:

		Effective Date
						January 15,				January 15,				January 15,				January 15,				January 15,
Stock Price		December 19, 2005				2007				2008				2009				2010				2011
$23.51			6.4917				6.6037				6.6780				6.7505				6.8068				7.2363
$24.00			5.8891				5.9743				6.0385				6.0721				6.0827				6.3679

$27.50			2.6275				2.6347				2.5987				2.5024				2.2930				1.0648
$30.00			1.2145				1.2037				1.1529				1.0469				0.8423				0.0000
$32.50			0.3652				0.3634				0.3225				0.2477				0.1171				0.0000
$35.00			0.1600				0.1500				0.1000				0.0700				0.0300				0.0000
$37.50			0.0800				0.0800				0.0500				0.0200				0.0000				0.0000
$40.00			0.0300				0.0200				0.0100				0.0000				0.0000				0.0000

     (f) If the exact Stock Price and Effective Date are not set forth on the table above, then:

     (i) If the Stock Price is between two Stock Price amounts in the table or the Effective Date is between two Effective Dates in the table, the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Price amounts and the two dates, as applicable, based on a 365-day year.

     (ii) If the Stock Price is in excess of $40.00 per share, subject to adjustment, the Issuer shall not increase the Conversion Rate by any Additional Shares.

     (iii) If the Stock Price is less than $23.51 per share, subject to adjustment, the Issuer shall not increase the Conversion Rate by any Additional Shares.

     Section 13.14. Conversion Right After Public Acquirer Change of Control.

     (a) Notwithstanding the foregoing, if a transaction described in clause (1) or (2) of the definition of Fundamental Change occurs prior to January 15, 2011, in lieu of adjusting the Conversion Rate as set forth in Section 13.13, the Issuer shall be permitted, in the case of a Public Acquirer Change of Control, at any time prior to the twentieth Business Day immediately preceding the proposed Effective Date of the Public Acquirer Change of Control, irrevocably elect to change the Conversion Obligation with respect to the Notes into an obligation to deliver, upon conversion of the Notes, cash and shares of Public Acquirer Common Stock, if any, equal to the Conversion Value in the same manner as the Issuer would otherwise be required to satisfy the Conversion Obligation pursuant to Section 13.12 in respect of the shares of Common Stock. If the Issuer makes such an election, the Conversion Rate applicable to any Notes converted after

such election shall be a number of shares of Public Acquirer Common Stock equal to the Conversion Rate in effect immediately before the Effective Date of the Public Acquirer Change of Control multiplied by a fraction:

     (i) the numerator of which will be (1) in the case of a share exchange, consolidation, merger, or binding share exchange pursuant to which the Common Stock is converted into cash, securities, or other property, the value of all cash, securities, and other property (as determined by the Board of Directors) paid or payable per share of Common Stock or (2) in the case of any other Public Acquirer Change of Control, the average of the Closing Sale Prices of the Common Stock for the five consecutive Trading Days prior to but excluding the Effective Date of such Public Acquirer Change of Control; and

     (ii) the denominator of which shall be the average of the Closing Sale Prices of the Public Acquirer Common Stock for the five consecutive Trading Days prior to but excluding the Effective Date of such Public Acquirer Change of Control.

     (b) If the Issuer elects to adjust the Conversion Rate and Conversion Obligation in connection with a Public Acquirer Change of Control pursuant to Section 13.14(a), the Issuer shall be required to send holders of Notes written notice not later than twenty (20) Business Days prior to but excluding the expected Effective Date of the Public Acquirer Change of Control. If the Issuer makes such an election, holders who tender their Notes for conversion shall not have the right to any increase in the Conversion Rate pursuant to Section 13.13.

     Section 13.15. Ownership Limit; Withholding Tax.

     (a) Notwithstanding any other provision of the Notes, no holder of Notes shall be entitled to receive shares of Common Stock upon a conversion of Notes to the extent that receipt of such shares would cause such holder (together with such holder’s Affiliates) to exceed the ownership limit contained in the Charter of the Issuer. In such case, the Issuer shall satisfy its obligation in respect of the Net Amount owing upon conversion solely in cash such that such holder shall be entitled to receive solely cash in respect of to the Conversion Value owing upon conversion of such holder’s Notes.

     (b) At the Maturity Date or upon earlier redemption or repurchase of the Notes or otherwise, and as otherwise required by law, the Issuer may deduct and withhold from the amount of consideration otherwise deliverable to the Holder the amount required to be deducted and withheld under applicable law.

     Section 13.16. Calculation In Respect of Notes. Except as otherwise specifically stated herein or in the Notes, all calculations to be made in respect of the Notes shall be the obligation of the Issuer. All calculations made by the Issuer or its agent as contemplated pursuant to the terms hereof and of the Notes shall be made in good faith and be final and binding on the Notes and the holders of the Notes absent manifest error. The Issuer shall provide a schedule of calculations to the Trustee, and the Trustee shall be entitled to rely upon the accuracy of the calculations by the Issuer without independent verification. The Trustee shall forward calculations made by the Issuer to any Holder of Notes upon request.

FORM OF REVERSE OF NOTE

UNITED DOMINION REALTY TRUST, INC.
4.00% CONVERTIBLE SENIOR NOTES DUE 2035

     This note is one of a duly authorized issue of notes of the Issuer, designated as its “4.00% Convertible Senior Notes due 2035” (herein called the “Notes”), issued under and pursuant to an Indenture, dated as of December 19, 2005 (herein called the “Indenture”), between the Issuer and SunTrust Bank, as trustee (herein called the “Trustee”), to which Indenture and all 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 Issuer 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.

     The Issuer shall not have the right to redeem the Notes prior to January 15, 2011, except to preserve its status as a real estate investment trust. If the Issuer determines it is necessary to redeem the Notes in order to preserve its status as a real estate investment trust, the Issuer may redeem the Notes for cash, in whole or in part, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed plus unpaid interest, if any, accrued thereon to, but excluding, the Redemption Date. At any time on or after January 15, 2011, the Notes may be redeemed at the option of the Issuer, in whole or in part, in cash at a redemption price equal to 100% of the principal amount of Notes to be redeemed plus accrued and unpaid interest accrued thereon to, but excluding, the Redemption Date. If an Interest Payment Date falls on or prior to the Redemption Date, then the interest payable on such Interest Payment Date shall be paid to the holders of record of the Notes on the applicable Record Date instead of the holders surrendering the Notes for redemption.

     Subject to the terms and conditions set forth in the Indenture, following the occurrence of Fundamental Change at any time prior to the Maturity Date, the Notes shall be subject to repurchase by the Issuer, at the option of the holder, on the Fundamental Change Repurchase Date, at a repurchase price equal to 100% of the principal amount of the Notes to be repurchased together with accrued and unpaid interest accrued thereon to, but excluding, the Fundamental Change Repurchase Date; provided that if an Interest Payment Date falls on or prior to the Fundamental Change Repurchase Date, then, with respect to any Note in respect of which the holder thereof shall have submitted a Repurchase Notice, the interest payable on such Interest Payment Date shall be paid to the holder of record of such Note on the applicable Record Date instead of the holder surrendering such Note for repurchase. To exercise such right, the holder shall be required to satisfy the conditions to such repurchase set forth in the Indenture and to deliver to the Paying Agent the Repurchase Notice set forth on the reverse hereof prior to the close of business on the Fundamental Change Repurchase Date.

     Subject to the terms and conditions of the Indenture, each holder shall have the right, at such holder’s option, to require the Issuer to repurchase all or any portion of the Notes held by such holder, on January 15, 2011, December 15, 2015, December 15, 2020, December 15, 2025 and December 15, 2030, at a repurchase price equal to 100% of the principal amount of the Notes to be repurchased together with any accrued and unpaid interest accrued thereon to, but excluding, the Repurchase Date; provided that if an Interest Payment Date falls on or prior to a

Repurchase Date, then, with respect to any Note in respect of which the holder thereof shall have submitted a Repurchase Notice, the interest payable on such Interest Payment Date shall be paid to the holder of record of such Note on the applicable Record Date instead of the holder surrendering such Note for repurchase. To exercise such right, the holder shall be required to satisfy the conditions to such repurchase set forth in the Indenture and deliver to the Paying Agent the Repurchase Notice set forth on the reverse hereof, at any time from the opening of business on the date that is twenty (20) Business Days prior to the applicable Repurchase Date until the close of business on the applicable Repurchase Date.

     The Issuer may not repurchase any Notes if there has occurred and is continuing an Event of Default with respect to the Notes (other than a default in the payment of the repurchase price for such Notes).

     Holders have the right to withdraw any Repurchase Notice by delivering to the Paying Agent a written notice of withdrawal at any time prior to the close of business on a Repurchase Date, all as provided in the Indenture.

     Subject to and in compliance with the provisions of the Indenture, holders of Notes shall have the right to convert each $1,000 principal amount of Notes at the applicable Conversion Rate into cash and, if applicable, shares of Common Stock, with an aggregate value equal to the Conversion Value as provided in the Indenture, upon surrender of the Note to be converted with the form entitled “Conversion Notice” on the reverse hereof duly completed and manually signed, to the Issuer at the office or agency of the Issuer maintained for that purpose in The City of New York in accordance with the terms of the Indenture, together with any funds required pursuant to the terms of the Indenture. The Conversion Rate shall initially be 35.2988 shares of Common Stock per $1,000 principal amount of Notes, subject to adjustment in the manner set forth in the Indenture.

     Notes surrendered for conversion at any time after the close of business on any applicable Record Date for the payment of interest and prior to the corresponding Interest Payment Date must be accompanied by payment, in immediately available funds or other funds acceptable to the Issuer, of an amount equal to the interest otherwise payable on such Interest Payment Date on the principal amount being converted; provided that no such payment shall be required (1) if the Issuer has specified a Redemption Date that is after a Record Date and on or prior to the corresponding Interest Payment Date, (2) if the Issuer has specified a Fundamental Change Repurchase Date that is after a Record Date and on or prior to the corresponding Interest Payment Date or (3) to the extent of any overdue interest (including Additional Interest), if any exists at the time of conversion with respect to this Note.

     In the event the holder surrenders this Note for conversion in connection with a Fundamental Change occurring prior to January 15, 2011, the Issuer shall increase the applicable Conversion Rate in accordance with the provisions of Section 13.13 of the Indenture unless the Issuer shall have made a Public Acquiror Change of Control election in accordance with the provisions of Section 13.14 of the Indenture.

     In the event that shares of Common Stock are issued upon conversion of Notes, no fractional shares shall be issued upon such conversion, but an adjustment and payment in cash

will be made, as provided in the Indenture, in respect of any fraction of a share which would otherwise be issuable upon such conversion.

     A Note in respect of which a holder has submitted a Repurchase Notice may be converted only if such holder validly withdraws such Repurchase Notice in accordance with the terms of the Indenture.

     If an Event of Default (other than an Event of Default specified in Section 6.01(h), 6.01(i) and 6.01(j)) with respect to the Issuer) shall occur and be continuing, the principal of, and accrued and unpaid interest on, the Notes may be declared to be due and payable in the manner specified in the Indenture. If an Event of Default specified in Section 6.01(h), 6.01(i) or 6.01(j) of the Indenture shall occur with respect to the Issuer, the principal of, and interest accrued and unpaid on, the Notes shall be immediately and automatically due and payable without necessity of further action. 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. Upon any such waiver, said default shall for all purposes of this Note and the 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 impair any right consequent thereon.

     The Indenture contains provisions permitting the Issuer 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 to modify provisions of the Indenture, subject to exceptions permitting the modification of the Indenture without the consent of any holder of Notes or requiring the consent of each holder of a Note affected by such modification all as set forth in Article 9 of the Indenture.

     The Notes are issuable in fully registered form, without coupons, in denominations of $1,000 principal amount and any multiple of $1,000. At the office or agency of the Issuer referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, without payment of any service charge but with payment of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in connection with any registration or exchange of Notes, Notes may be exchanged for a like aggregate principal amount of Notes of any other authorized denominations. Upon surrender for registration of transfer of any Note to the Note Registrar or any co-registrar, and satisfaction of the requirements for such transfer set forth in the Indenture, the Issuer shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denominations and of a like aggregate principal amount and bearing such restrictive legends as may be required by the Indenture. No service charge shall be made to any holder for any registration of transfer or exchange of Notes, but the Issuer may require payment by the holder of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes.

     The Issuer, the Trustee, any Paying Agent, any Conversion Agent and any Note Registrar may deem the Person in whose name this Note shall be registered upon the Note Register to be, and may treat it as, the absolute owner of this Note (whether or not this 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, and interest on this Note, for conversion of this Note and for all other purposes; and neither the Issuer or the Trustee nor any Paying Agent, Conversion Agent or any Note Registrar shall be affected by any notice to the contrary. All such payments so made to any holder for the time being, or upon its order, shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for monies payable upon any this Note.
