The transfer and exchange of beneficial interests in a Global Note that does not involve the issuance of a Note in certificated form, shall be effected through the Depositary (but not the Trustee or the Custodian) in accordance with this Indenture (including the restrictions on transfer set forth herein) and the procedures of the Depositary therefor.

Any Defaulted Interest shall forthwith cease to be payable to the Noteholder on the relevant Interest Record Date by virtue of its having been such Noteholder, and such Defaulted Interest shall be paid by the Company, at its election in each case, as provided in clause (1) or (2) below:

(1) The Company 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 the close of business on a special record date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Note and the date of the proposed payment (which shall be not less than twenty-five 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 Company 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 Company shall fix a special record date for the payment of such Defaulted Interest which shall be not more than fifteen days and not less than ten days prior to the date of the proposed payment, and not less than ten days after the receipt by the Trustee of the notice of the proposed payment. The Company shall promptly notify the Trustee of such special record date and the Trustee, in the name and at the expense of the

Company, shall cause notice of the proposed payment of such Defaulted Interest and the special record date therefor to be mailed, first-class mail, postage prepaid, to each holder at its address as it appears in the Note Register, not less than ten days prior to such special record date.

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

Section 2.04 Payments of Additional Interest. Whenever in this Indenture there is mentioned, in any context, the payment of interest on, or in respect of, any Note, such mention shall be deemed to include mention of the payment of “Additional Interest” as provided for in this Indenture to the extent that, in such context, Additional Interest is, was or would be payable in respect thereof pursuant to the provisions of this Indenture or express mention of the payment of Additional Interest (if applicable) in any provisions hereof shall not be construed as excluding Additional Interest, as the case may be, in those provisions hereof where such express mention is not made.

At such time as all interests in a Global Note have been converted, canceled, redeemed, repurchased or transferred, such Global Note shall be, upon receipt thereof, 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 exchanged for Notes in certificated form, converted, canceled, redeemed, repurchased or transferred to a transferee who receives Notes in certificated form therefor or any definitive Note is exchanged or transferred for part of such Global Note, 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 or increased, as the case may be, and an endorsement shall be made on such Global Note, by the Trustee or the Custodian, at the direction of the Company, to reflect such reduction or increase.

Notes in certificated form issued in exchange for all or a part of the Global Note pursuant to this Section 2.06(c) shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee.

Every substitute Note issued pursuant to the provisions of this Section 2.07 by virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, 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 conversion 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 conversion of negotiable instruments or other securities without their surrender.

Every such temporary Note shall be executed by the Company 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 Company will execute and deliver to the Trustee or such authenticating agent Notes in certificated form (other than any Global Note) and thereupon any or all temporary Notes (other than any Global Note) may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 5.02 and the Trustee or such authenticating agent shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of Notes in certificated form. Such exchange shall be made by the Company 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.

REDEMPTION

Section 3.01 Company’s Right to Redeem; Notices to Trustee. Prior to July 1, 2013, the Notes shall not be redeemable at the Company’s option. On or after July 1, 2013, the Company, at its option, may redeem the Notes for cash at any time, or from time to time, in whole or in part, at a redemption price (the “Redemption Price”) equal to 100% of the principal amount of the Notes redeemed, plus any accrued and unpaid interest, and accrued and unpaid Additional Interest, if any, on the Notes redeemed up to, but not including, the Redemption Date; provided, however, that, in no event shall a Redemption Date be a Legal Holiday; provided, further, that, if the Redemption Date is on a date that is after an Interest Record Date and on or prior to the corresponding Interest Payment Date, the Redemption Price shall be 100% of the principal amount of the Notes redeemed but shall not include accrued and unpaid interest and accrued and unpaid Additional Interest, if any. Instead, the Company shall pay such interest and Additional Interest, if any, on the Interest Payment Date to the holder of record on the corresponding Interest Record Date. If the Company elects to redeem Notes pursuant to this Section 3.01, it shall notify the Trustee in writing of such election together with the Redemption Date, the Conversion Rate, the principal amount of Notes to be redeemed and the Redemption Price. Notwithstanding the foregoing, no Notes may be redeemed by the Company if the principal amount of the Notes has been accelerated and such acceleration has not been rescinded on or prior to the Redemption Date (except in the case of an acceleration resulting from a default by the Company in the payment of the Redemption Price with respect to such Notes).

The Company shall give the notice to the Trustee provided for in this Section 3.01 by a Company Order, at least 45 days but not more than 60 days before the Redemption Date (unless a shorter notice shall be satisfactory to the Trustee).

Section 3.02 Selection of Notes to Be Redeemed. If less than all of the Notes are to be redeemed, unless the procedures of the Depositary provide otherwise, the Trustee shall select the Notes to be redeemed by lot, on a pro rata basis or by another method the Trustee considers fair and appropriate (so long as such method is not prohibited by the rules of any stock exchange or quotation association on which the Notes are then traded or quoted).

Notes and portions of Notes that the Trustee selects shall be in principal amounts of $1,000 or an integral multiple of $1,000. Provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. The Trustee shall notify the Company promptly (but in any case within 7 days of the Company Order referred to in Section 3.01) of the Notes or portions of the Notes selected to be redeemed and, in the case of any Notes selected for partial redemption, the method it has chosen for the selection of the Note.

Section 3.03 Notice of Redemption. At least 30 days but not more than 60 days before a Redemption Date, the Company shall provide a notice of redemption by electronic transmission or first-class mail, postage prepaid, to each holder of Notes to be redeemed. Simultaneously with the providing of such notice, the Company shall also publish a notice containing the information set forth in the notice of redemption in a newspaper of general circulation in The City of New York or publish such information on the Company’s website or through such other public medium as the company may use at that time.

The notice shall identify the Notes to be redeemed and shall state (along with any other information the Company wishes to include):

(i) the Redemption Date;

(ii) the Redemption Price;

(iii) the Conversion Rate and the Conversion Price;

(iv) the name and address of the Paying Agent and Conversion Agent;

(v) that Notes may be converted at any time before the close of business on the Business Day prior to the Redemption Date;

(vi) that Notes called for redemption and not converted shall be redeemed on the Redemption Date;

(vii) that holders who want to convert their Notes must satisfy the requirements set forth in the Notes;

(viii) that Notes called for redemption must be surrendered to the Paying Agent (by effecting book-entry transfer of the Notes or delivering Notes in certificated form, together with necessary endorsements, as the case may be) to collect the Redemption Price;

(ix) if fewer than all of the outstanding Notes are to be redeemed, the certificate numbers, if any, and principal amounts of the particular Notes to be redeemed;

(x) that, unless the Company defaults in making payment of such Redemption Price, interest and Additional Interest, if any, on the Notes or portions of Notes called for redemption shall cease to accrue from and after the Redemption Date; and

(xi) the CUSIP, “ISIN” or other similar number(s), as the case may be, of the Notes being redeemed.

At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at the Company’s expense, provided that, the Company makes such request at least seven Business Days (or such shorter period as may be satisfactory to the Trustee) prior to the date by which such notice of redemption must be given to holders in accordance with this Section 3.03.

Section 3.04 Effect of Notice of Redemption. Once notice of redemption is given, Notes called for redemption become due and payable on the Redemption Date and at the Redemption Price stated in the notice except for Notes that are converted in accordance with the terms of this Indenture. Upon surrender to the Paying Agent, such Notes shall be paid at the Redemption Price stated in the notice and from and after the Redemption Date (unless the Company shall default in the payment of the Redemption Price) such Notes shall cease to bear interest and Additional Interest, if any, and the rights of the holders therein shall terminate (other than the right to receive the Redemption Price).

If any Note shall not be fully and duly paid in accordance herewith upon redemption, the principal of, and accrued and unpaid interest and accrued and unpaid Additional Interest, if any, on such Note shall, until paid, bear Interest at the rate borne by such Note on the principal amount of such Note, and such Note shall continue to be convertible pursuant to Article 14.

Section 3.05 Deposit of Redemption Price. Prior to 10:00 a.m. (New York City time), on the Redemption Date, the Company shall deposit with the Paying Agent (or if the Company is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the Redemption Price of all Notes to be redeemed on that date other than Notes or portions of Notes called for redemption which on or prior thereto have been delivered by the Company to the Trustee for cancellation or have been converted. The Paying Agent shall as promptly as practicable return to the Company any money not required for that purpose because of conversion of Notes pursuant to Article 14. If such money is then held by the Company in trust and is not required for such purpose it shall be discharged from such trust.

Section 3.06 Notes Redeemed in Part. Upon surrender of a Note that is redeemed in part, the Company shall execute and the Trustee shall, without charge, authenticate and deliver to the holder a new Note in an authorized denomination equal in principal amount to the unredeemed portion of the Note surrendered.

Unless and until a Responsible Officer of the Trustee receives at the Corporate Trust Office such a certificate, the Trustee may assume without inquiry that no such Additional Interest is payable. If the Company has paid Additional Interest directly to the Persons entitled to them, the Company shall deliver to the Trustee an Officers’ Certificate setting forth the particulars of such payment.

Section 5.10 Additional Interest Payable Upon Failure to Report or Delegend.

The Additional Interest payable pursuant to this Section 5.10(a) shall be payable on the Interest Payment Date following the late filing (after giving effect to the aggregate cure period described in the immediately preceding sentence).

(b) Unless:

(i) the legend on the Notes and any Common Shares issued upon conversion of the Notes required by Section 2.06(c) and Section 2.06(f) has been removed, and

(ii) the Notes and such Common Shares are freely tradable pursuant to Rule 144 under the Securities Act without volume restrictions by holders other than Affiliates of the Company,

then, as of the 365th day after the last date of original issuance of the Notes, the Company shall pay Additional Interest on the Notes at an annual rate equal to 0.25% of the aggregate principal amount of the Notes.

When such registration default ceases to continue (or both conditions described in (i) and (ii) of this Section 5.10(b) have been satisfied), accrued and unpaid Additional Interest through the date of cessation (or satisfaction) shall be paid in cash on the subsequent Interest Payment Date to the record holder and Additional Interest shall cease to accrue on the date of cessation (or satisfaction). In no event shall Additional Interest accrue at an annual rate in excess of 0.50%, in the aggregate, pursuant to this Section 5.10 and Section 7.01. In the event that the Company becomes obligated to pay additional interest under this Section 5.10(a) or (b), such interest shall be the sole remedy of holders and no Event of Default shall result (other than from any failure to pay such interest when due and payable).

During the period of one year after the last original issuance date of the Notes, the Company shall not, and shall not permit any of its controlled “affiliates” (as defined under Rule 144 under the Securities Act or any successor provision thereto) to, resell any Notes which constitute “restricted securities” under Rule 144 that have been reacquired by any of them.

Section 5.12 Further Instruments and Acts. From time to time whenever reasonably requested by the Trustee, the Company will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture.

Section 5.13 Special Veto Rights. Without the prior written consent of the holders of two-thirds in aggregate principal amount of the outstanding Notes, the Company shall be prohibited from (i) issuing new Common Shares to any “person” or “group” within the meaning of Section 13(d) of the Exchange Act that has become, or as a result of such issuance would become, the direct or indirect ultimate “beneficial owner”, as defined in Rule 13d-3 of the Exchange Act, of the Common Shares representing more than 50% of the voting power of the Common Shares or (ii) repurchasing any of the Company’s outstanding Common Shares at a time when a “person” or “group” (as defined above) has become the direct or indirect ultimate “beneficial owner” (as defined above) of more than 50% of the voting power of the Common Shares, in each case (i) and (ii) until the earlier of such time when (x) such person or group ceases to beneficially own 50% of the voting power of the Common Shares or (y) a Make-Whole Fundamental Change has occurred. Notwithstanding the foregoing, the prior written consent of the holders of two-thirds in aggregate principal amount of the outstanding Notes shall be required only to the extent the Current Market Price of the Common Shares over the 10 consecutive Trading Days preceding the date of such issuance or repurchase such acquisition date does not exceed $150.00 (subject to adjustment in the same manner as the Share Price, as provided in Section 14.03(a)(iii)).

This provision, however, is subject to the conditions that if, at any time after the principal of 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, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay installments of accrued and unpaid interest and accrued and unpaid Additional Interest, if any, upon all Notes and the principal of and premium, if any, on any and all Notes that shall have become due otherwise than by acceleration (with interest on overdue installments of accrued and unpaid interest and accrued and unpaid Additional Interest, if any, (to the extent that payment of such interest is enforceable under applicable law) and on such principal and premium, if any, at the rate borne by the Notes at such time) and amounts due to the Trustee pursuant to Section 8.06, and if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) any and all Events of Defaults under this Indenture, other than the nonpayment of principal of and premium, if any, and accrued and unpaid interest and accrued and unpaid Additional Interest, if any, on Notes that shall have become due solely by such acceleration, shall have been cured or waived pursuant to Section 7.07, then and in every such case the holders of a majority in aggregate principal amount of the Notes then outstanding, by written notice to the Company and to the Trustee, may waive all Defaults or Events of Default with respect to the Notes (other than a Default or an Event of Default resulting from a failure to redeem any Notes on any Redemption Date, a failure to repurchase any Notes when required upon a Repurchase Date or a Fundamental Change Repurchase Date or a failure to deliver, upon conversion, cash, Common Shares or a combination of cash and Common Shares, as applicable, due upon conversion) and rescind and annul such

declaration and its consequences (other than a declaration or consequences, as the case may be, resulting from a failure to redeem any Notes on any Redemption Date, a failure to repurchase any Notes when required upon a Repurchase Date or a Fundamental Change Repurchase Date or a failure to deliver, upon conversion, cash, Common Shares or a combination of cash and Common Shares, as applicable, due upon conversion) and such Default (other than a Default resulting from a failure to redeem any Notes on any Redemption Date, a failure to repurchase any Notes when required upon a Repurchase Date or a Fundamental Change Repurchase Date or a failure to deliver, upon conversion, cash, Common Shares or a combination of cash and Common Shares, as applicable, due upon conversion) shall cease to exist, and any Event of Default arising therefrom (other than a Default resulting from a failure to redeem any Notes on any Redemption Date, a failure to repurchase any Notes when required upon a Repurchase Date or a Fundamental Change Repurchase Date or a failure to deliver, upon conversion, cash, Common Shares or a combination of cash and Common Shares, as applicable, due upon conversion) shall be deemed to have been cured for every purpose of this Indenture; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon.

Notwithstanding anything in this Indenture or in the Notes to the contrary, for the first year immediately following any violation of any obligations the Company may be deemed to have pursuant to (1) Section 314(a)(1) of the Trust Indenture Act, or (2) Section 5.06(b), and during the continuation of such violation, the sole remedy for any such violation shall be the accrual of additional interest on the Notes at a rate per year equal to 0.25% of the outstanding principal amount of the Notes (“Supplementary Interest”), payable semi-annually at the same time and in the same manner as regular interest on the Notes pursuant to Section 2.03 and Section 5.01. In no event shall Supplementary Interest accrue at a rate per year in excess of 0.25%, regardless of the number of events or circumstances giving rise to the requirement to pay Supplementary Interest. In addition to the accrual of Supplementary Interest, on and after (but not before) the 365th day following, any violation of any obligations the Company may be deemed to have pursuant to (1) Section 314(a)(1) of the Trust Indenture Act or (2) Section 5.06(b), and during the continuation of such violation, either the Trustee or the Noteholders of not less than 25% in aggregate principal amount of the Notes then outstanding may declare the principal amount of the Notes and any accrued and unpaid interest, including any Additional Interest, through the date of such declaration, to be immediately due and payable. With regard to any violation of the kind specified in this paragraph, no Supplementary Interest shall accrue, and no right to declare the principal or other amounts to be due and payable in respect of the Notes shall exist, after such violation has been cured. Whenever in this Indenture there is mentioned, in any context, the payment of interest on, or in respect of, any Note, such mention shall be deemed to include mention of the payment of “Supplementary Interest” provided for in this paragraph to the extent that, in such context, Supplementary Interest is, was or would be payable in respect thereof pursuant to the provisions of this paragraph, and express mention of the payment of Supplementary Interest (if applicable) in any provisions hereof shall not be construed as excluding Supplementary Interest in those provisions hereof where such express mention is not made.

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 Company, the Noteholders, and the Trustee shall, subject to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Noteholders, and the Trustee shall continue as though no such proceeding had been instituted.

Section 7.02 Payments of Notes on Default; Suit Therefor. If an Event of Default described in clause (a) or (b) of Section 7.01 shall have occurred, the Company shall, upon demand of the Trustee, pay to it, for the benefit of the holders of the Notes, the whole amount then due and payable on the Notes for principal, premium, if any, and interest and Additional Interest, if any, with interest on any overdue principal, premium, if any, interest and Additional Interest, if any, at the rate borne by the Notes at such time, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee under Section 8.06. If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon the Notes, wherever situated.

In the event there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor on the Notes under title 11 of the United States Code, 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 Company or such other obligor, the property of the Company or such other obligor, or in the event of any other judicial proceedings relative to the Company or such other obligor upon the Notes, or to the creditors or property of the Company 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 7.02, 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 of and premium, if any (including the Redemption Price, the Repurchase Price or the Fundamental Change Repurchase Price), and accrued and unpaid interest and accrued and unpaid Additional Interest, if any, in respect of the Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents and to take such other actions as it may deem necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Noteholders allowed in such judicial proceedings relative to the Company 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 8.06; 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, as administrative expenses, 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 agents and counsel fees, and including any other amounts due to the Trustee under Section 8.06 hereof, 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 that 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.

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Noteholder any plan of reorganization, arrangement, adjustment or composition affecting the Noteholder or the rights of any Noteholder thereof, or to authorize the Trustee to vote in respect of the claim of any Noteholder in any such proceeding.

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 7.03 Application of Monies Collected by Trustee. Any monies collected by the Trustee pursuant to this Article 7 with respect to the Notes shall be applied in the order following, 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 8.06;

Second, in case the principal of the outstanding Notes shall not have become due and be unpaid, to the payment of interest on the Notes and Additional Interest, if any, in default in the order of the date due of the installments of such interest, with interest (to the extent that such interest has been collected by the Trustee) upon the overdue installments of interest at the rate borne by the Notes at such time, 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 including the payment of the Redemption Price, the Repurchase Price or the Fundamental Change Repurchase Price and the cash component of the Conversion Obligation, if any, then owing and unpaid upon the Notes for principal and premium, if any, and interest, including Additional Interest, if any, with interest on the overdue principal and premium, if any, and (to the extent that such interest has been collected by the Trustee) upon overdue installments of interest at the rate borne by the Notes at such time, 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 premium, if any, and interest without preference or priority of principal and premium, if any, over interest, or of interest over principal and premium, if any, 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 premium, if any, and accrued and unpaid interest; and

Fourth, to the payment of the remainder, if any, to the Company.

Section 7.04 Proceedings by Noteholders. No holder of any Note shall have any right by virtue of or by availing of 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, unless such holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as hereinbefore provided, and unless also the holders of not less than 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 security or indemnity reasonably satisfactory to it against any loss, liability or expense to be incurred therein or thereby, and the Trustee for sixty 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 no direction that, in the opinion of the Trustee, is inconsistent with such written request shall have been given to the Trustee by the holders of a majority in principal amount of the Notes outstanding within such sixty-day period pursuant to Section 7.07; 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 Noteholders shall have any right in any manner whatever by virtue of or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any other Noteholder (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Noteholders), 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 Noteholders (except as otherwise provided herein). For the protection and enforcement of this Section 7.04, 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 Noteholder to receive payment of the principal of and premium, if any (including the Redemption Price upon redemption pursuant to Article 3, the Repurchase Price upon repurchase pursuant to Section 15.01 and the Fundamental Change Repurchase Price upon repurchase pursuant to Section 15.04), and accrued and unpaid interest and accrued and unpaid Additional Interest, if any, on such Note, on or after the respective due dates expressed or provided for in such Note or in this Indenture, or to institute suit for the enforcement of any such payment on or after such respective dates against the Company shall not be impaired or affected without the consent of such Noteholder.

Anything 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 7.05 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 7.06 Remedies Cumulative and Continuing. Except as provided in the last paragraph of Section 2.07, all powers and remedies given by this Article 7 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 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 7.04, every power and remedy given by this Article 7 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 7.07 Direction of Proceedings and Waiver of Defaults by Majority of Noteholders. The holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 9.04 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 with respect to Notes; provided, however, that (a) such direction shall not be in conflict with any rule of law or with this Indenture, and (b) the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may refuse to follow any direction that it determines is unduly prejudicial to the rights of any other holder or that would involve the Trustee in personal liability. The holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 9.04 (including, without limitation, by consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes) 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 premium (including any Redemption Price, any Repurchase Price or any Fundamental Change Repurchase Price), if any, accrued and unpaid interest or accrued and unpaid Additional Interest, if any, on, or the principal of, the Notes when due that has not been cured pursuant to the provisions of Section 7.01, (ii) a failure by the Company to deliver cash, Common Shares or a combination of cash and Common Shares, as applicable, upon conversion of the Notes or (iii) a default in respect of a covenant or provision hereof which under Article 11 cannot be modified or amended without the consent of each holder of an outstanding Note affected. Upon any such waiver the Company, 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 7.07, 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 7.08 Notice of Defaults. The Trustee shall, within ninety days after the occurrence and continuance of a Default of which a Responsible Officer has actual knowledge, 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; and provided that, except in the case of a Default in the payment of the principal of, or premium, if any, accrued and unpaid interest or accrued and unpaid Additional Interest, if any, on any of the Notes, including without limiting the generality of the foregoing any Default in the payment of any Redemption Price, any Repurchase Price or any Fundamental Change Repurchase Price, then in any such event the Trustee shall be protected in withholding such notice if and so long as a committee of Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interests of the Noteholders.

Section 7.09 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 7.09 (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 10% in principal amount of the Notes at the time outstanding determined in accordance with Section 9.04, or to any suit instituted by any Noteholder for the enforcement of the payment of the principal of or premium, if any, accrued and unpaid interest or accrued and unpaid Additional Interest, if any, on any Note (including, but not limited to, the Redemption Price, the Repurchase Price and the Fundamental Change Repurchase Price with respect to the Notes being redeemed or repurchased, as applicable, as provided in this Indenture) on or after the due date expressed or provided for in such Note or to any suit for the enforcement of the right to convert any Note in accordance with the provisions of Article 14.

ARTICLE 8

CONCERNING THE TRUSTEE

Section 8.01 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 that 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 such person’s own affairs; provided that, if an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any of the holders unless such holders have offered to the Trustee indemnity or security satisfactory to it against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction.

No provision of this Indenture shall be construed to relieve the Trustee from liability for its own grossly negligent action, its own grossly 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 that may have occurred:

(i) the duties and obligations of the Trustee shall be determined solely by the express provisions of this Indenture and, after it has been qualified thereunder, 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 that 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 (but need not confirm or investigate the accuracy of any mathematical calculations or other facts stated therein);

(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 it shall be proved that the Trustee was grossly 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 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 9.04 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 8.01;

(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 Company or any Paying Agent or any records maintained by any co-registrar 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 such Responsible Officer of the Trustee had actual knowledge of such event;

(g) in the absence of specific written investment direction from the Company, all cash received by the Trustee shall be placed in a non-interest bearing trust account, and in no event shall the Trustee be liable for the selection of investments or for investment losses, fees, taxes or other charges incurred thereon or for losses incurred as a result of the liquidation of any such investment prior to its maturity date or the failure of the party directing such investments prior to its maturity date or the failure of the party directing such investment to provide timely written investment direction, and the Trustee shall have no obligation to invest or reinvest any amounts held hereunder in the absence of such written investment direction from the Company; and

(h) in the event that the Trustee is also acting as Custodian, Note Registrar, Paying Agent, Conversion Agent or transfer agent hereunder, the rights and protections afforded to the Trustee pursuant to this Article 8 shall also be afforded to such Custodian, Note Registrar, Paying Agent, Conversion Agent or transfer agent.

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.

Section 8.02 Reliance on Documents, Opinions, Etc. Except as otherwise provided in Section 8.01:

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

(d) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the Noteholders pursuant to the provisions of this Indenture, unless such Noteholders shall have offered to the Trustee security or indemnity satisfactory to it against the costs, expenses and liabilities that may be incurred therein or thereby;

(e) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney at the expense of the Company and shall incur no liability of any kind by reason of such inquiry or investigation;

(f) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents, custodians, nominees or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent, custodian, nominee or attorney appointed by it with due care hereunder;

(g) the permissive rights of the Trustee enumerated herein shall not be construed as duties; and

(h) the Trustee may request that the Company deliver a certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture.

In no event shall the Trustee be liable for any consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action other than any such loss or damage caused by the Trustee’s willful misconduct or gross negligence. The Trustee shall not be charged with knowledge of any Default or Event of Default with respect to the Notes, unless either (1) a Responsible Officer shall have actual knowledge of such Default or Event of Default or (2) written notice of such Default or Event of Default shall have been given to the Trustee by the Company or by any holder of the Notes.

Section 8.03 No Responsibility for Recitals, Etc. The recitals contained herein and in the Notes (except in the Trustee’s certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Notes. The Trustee shall not be accountable for the use or application by the Company of any Notes or the proceeds of any Notes authenticated and delivered by the Trustee in conformity with the provisions of this Indenture.

Section 8.04 Trustee, Paying Agents, Conversion Agents or Registrar May Own Notes. The Trustee, any Paying Agent, any Conversion 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 the Trustee, Paying Agent, Conversion Agent or Note Registrar.

Section 8.05 Monies to Be Held in Trust. 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. Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as may be agreed in writing from time to time by the Company and the Trustee.

Section 8.06 Compensation and Expenses of Trustee. The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, such compensation as shall be agreed in writing 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 in writing between the Trustee and the Company, and the Company 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 in any capacity thereunder (including the reasonable compensation and the expenses and disbursements of its agents and counsel and of all Persons not regularly in its employ) except any such expense, disbursement or advance as shall have been caused by its gross negligence, willful misconduct or bad faith. The

Company also covenants to indemnify the Trustee in any capacity under this Indenture and any other document or transaction entered into in connection herewith and its agents and any authenticating agent for, and to hold them harmless against, any loss, claim, damage, liability or expense incurred without gross negligence, willful misconduct or bad faith on the part of the Trustee, its officers, directors, agents or employees, or such agent 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 costs and expenses of defending themselves against any claim of liability in the premises. The obligations of the Company under this Section 8.06 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall be secured by a senior claim to which the Notes are hereby made subordinate on all money or property held or collected by the Trustee, except, subject to the effect of Section 7.03, funds held in trust herewith for the benefit of the holders of particular Notes. The Trustee’s right to receive payment of any amounts due under this Section 8.06 shall not be subordinate to any other liability or indebtedness of the Company (even though the Notes may be so subordinated). The obligation of the Company under this Section 8.06 shall survive the satisfaction and discharge of this Indenture and the earlier resignation or removal or the Trustee. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The indemnification provided in this Section 8.06 shall extend to the officers, directors, agents and employees of the Trustee.

Without prejudice to any other rights available to the Trustee under applicable law, when the Trustee and its agents and any authenticating agent incur expenses or render services after an Event of Default specified in Section 7.01(h) or Section 7.01(i) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any bankruptcy, insolvency or similar laws.

Section 8.07 Officers’ Certificate as Evidence. Except as otherwise provided in Section 8.01, 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, willful misconduct, recklessness and bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an Officers’ Certificate delivered to the Trustee, and such Officers’ Certificate, in the absence of gross negligence, willful misconduct, recklessness and bad faith on the part of the Trustee, shall be full warrant to the Trustee for any action taken or omitted by it under the provisions of this Indenture upon the faith thereof.

Section 8.08 Conflicting Interests of Trustee. After qualification of this Indenture under the Trust Indenture Act, if the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either (a) eliminate such interest within ninety days, (b) apply to the Commission for permission to continue as Trustee or (c) resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture.

Section 8.09 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 $50,000,000. 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 8.09, 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 8.09, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.

Section 8.10 Resignation or Removal of Trustee.

(a) The Trustee may at any time resign by giving written notice of such resignation to the Company and by mailing notice thereof to the Noteholders at their addresses as they shall appear on the Note Register. Upon receiving such notice of resignation, the Company 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 within sixty days after the mailing of such notice of resignation to the

Noteholders, the resigning Trustee may, at the expense of the Company, upon ten Business Days’ notice to the Company and the Noteholders, petition any court of competent jurisdiction for the appointment of a successor trustee, or any Noteholder who has been a bona fide holder of a Note or Notes for at least six months may, subject to the provisions of Section 7.09, on behalf of himself and all others similarly situated, petition any such court 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 8.08 within a reasonable time after written request therefor by the Company 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 8.09 and shall fail to resign after written request therefor by the Company 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 Company may by a Board Resolution 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 7.09, any Noteholder who has been a bona fide holder of a Note or Notes for at least six months may, on behalf of himself 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) The holders of a majority in aggregate principal amount of the Notes at the time outstanding, as determined in accordance with Section 9.04, may at any time remove the Trustee and nominate a successor trustee that shall be deemed appointed as successor trustee unless within ten days after notice to the Company of such nomination the Company objects thereto, in which case the Trustee so removed or any Noteholder, upon the terms and conditions and otherwise as in Section 8.10(a) provided, may, at the expense of the Company, petition any court of competent jurisdiction for an appointment of a successor trustee.

(d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section 8.10 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 8.11.

Section 8.11 Acceptance by Successor Trustee. Any successor trustee appointed as provided in Section 8.10 shall execute, acknowledge and deliver to the Company 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 Company or of the successor trustee, the trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of Section 8.06, 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 Company 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 senior claim to which the Notes are hereby made subordinate on all money or property 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 8.06.

No successor trustee shall accept appointment as provided in this Section 8.11 unless at the time of such acceptance such successor trustee shall be qualified under the provisions of Section 8.08 and be eligible under the provisions of Section 8.09.

Upon acceptance of appointment by a successor trustee as provided in this Section 8.11, each of the Company and the successor trustee, at the written direction and at the expense of the Company shall mail or cause to be mailed notice of the succession of such trustee hereunder to the Noteholders at their addresses as they shall appear on the Note Register. If the Company fails to mail such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Company.

Section 8.12 Succession by Merger, Etc. Any corporation or other entity into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation or other entity resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation or other entity succeeding to all or substantially all of the corporate trust business of the Trustee (including the administration of 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 or other entity succeeding to all or substantially all of the corporate trust business of the Trustee such corporation or other entity shall be qualified under the provisions of Section 8.08 and eligible under the provisions of Section 8.09.

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 an authenticating agent appointed by such successor trustee may authenticate such Notes either in the name of any predecessor trustee hereunder or in the name of the successor trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall have; provided, however, that the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Notes in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation.

Section 8.13 Limitation on Rights of Trustee as Creditor. If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Notes), after qualification under the Trust Indenture Act, the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of the claims against the Company (or any such other obligor).

Section 8.14 Trustee’s Application for Instructions from the Company. Any application by the Trustee for written instructions from the Company (other than with regard to any action proposed to be taken or omitted to be taken by the Trustee that affects the rights of the holders of the Notes under this Indenture) may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than three Business Days after the date any officer that the Company has indicated to the Trustee should receive such application actually receives such application, unless any such officer shall have consented in writing to any earlier date), unless, prior to taking any such action (or the effective date in the case of any omission), the Trustee shall have received written instructions in accordance with this Indenture in response to such application specifying the action to be taken or omitted.

CONCERNING THE NOTEHOLDERS

Section 9.01 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 Noteholders voting in favor thereof at any meeting of Noteholders duly called and held in accordance with the provisions of Article 10, or (c) by a combination of such instrument or instruments and any such record of such a meeting of Noteholders. Whenever the Company or the Trustee solicits the taking of any action by the holders of the Notes, the Company or the Trustee may fix, but shall not be required to, in advance of such solicitation, a date as the record date for determining Noteholders entitled to take such action. The record date if one is selected shall be not more than fifteen days prior to the date of commencement of solicitation of such action.

Section 9.02 Proof of Execution by Noteholders. Subject to the provisions of Section 8.01, Section 8.02 and Section 10.05, 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.

Section 9.03 Who Are Deemed Absolute Owners. The Company, the Trustee, any authenticating agent, any Paying Agent, any Conversion Agent and any Note Registrar may deem the Person in whose name a 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 Company or any Note Registrar) for the purpose of receiving payment of or on account of the principal of, premium (including the payment of the Redemption Price, the Repurchase Price and the Fundamental Change Repurchase Price), if any, and (subject to Section 2.03) accrued and unpaid interest and accrued and unpaid Additional Interest, if any, on such Note, for conversion of such Note and for all other purposes; and neither the Company 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. Notwithstanding anything to the contrary in this Indenture or the Notes following an Event of Default, any holder of a beneficial interest in a Global Note may directly enforce against the Company, without the consent, solicitation, proxy, authorization or any other action of the Depositary or any other Person, such holder’s right to exchange such beneficial interest for a Note in certificated form in accordance with the provisions of this Indenture.

Section 9.04 Company-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 that are owned by the Company or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company 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 that a Responsible Officer actually knows are so owned shall be so disregarded. Notes so owned that have been pledged in good faith may be regarded as outstanding for the purposes of this Section 9.04 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to so act with respect to such Notes and that the pledgee is not the Company or a Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company. 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. The Company shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above

described Persons; and, subject to Section 8.01, 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 9.05 Revocation of Consents; Future Holders Bound. At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 9.01, 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 that 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 9.02, 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 or upon registration of transfer thereof, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor or upon registration of transfer thereof.

(b) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing under this Indenture.

Upon any such amalgamation, consolidation, merger, conveyance, transfer or lease the Successor Company (if not the Company) shall succeed to, and may exercise every right and power of, the Company under this Indenture.

For purposes of this Section 12.01, the conveyance, transfer or lease of the properties and assets of one or more Subsidiaries of the Company substantially as an entirety to another Person, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute the properties and assets of the Company substantially as an entirety on a consolidated basis, shall be deemed to be the transfer of the properties and assets of the Company substantially as an entirety to another Person.

Section 12.02 Successor Corporation to Be Substituted. In case of any such amalgamation, consolidation, merger, conveyance, transfer or lease and upon the assumption by the Successor Company, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal of and premium (including any Redemption Price, Repurchase Price or Fundamental Change Repurchase Price), if any, accrued and unpaid interest and accrued and unpaid Additional Interest, if any, on all of the Notes, the due and punctual delivery or payment, as the case may be, of any consideration due upon conversion of the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Company under this Indenture, such Successor Company shall succeed to and be substituted for, and may exercise every right and power of, the Company under this Indenture, with the same effect as if it had been named herein as the party of the first part. Such Successor Company thereupon may cause to be signed, and may issue either in its own name or in the name of the Company any or all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such Successor Company instead of the Company 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 Company to the Trustee for authentication, and any Notes that such Successor Company 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

amalgamation, consolidation, merger, conveyance or transfer (but not in the case of a lease), the Person named as the “Company” in the first paragraph of this Indenture or any successor that shall thereafter have become such in the manner prescribed in this Article 12 may be dissolved, wound up and liquidated at any time thereafter and, except in the case of a lease, such Person shall be released from its liabilities as obligor and maker of the Notes and from its obligations under this Indenture.

In case of any such amalgamation, consolidation, merger, conveyance, transfer or lease, 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 12.03 Opinion of Counsel to Be Given to Trustee. No amalgamation, merger, consolidation, conveyance, transfer or lease shall be effective unless the Trustee shall receive an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any such amalgamation, consolidation, merger, conveyance, transfer or lease and any such assumption and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, complies with the provisions of this Article 12.

ARTICLE 14

CONVERSION OF NOTES

Section 14.01 Conversion Privilege.

A Noteholder shall have the right, at such holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral multiple thereof) of such Note at any time beginning on the date hereof and ending prior to the close of business on the Business Day immediately preceding the Maturity Date, in each case, at an initial conversion rate (the “Conversion Rate”) of 95.6938 Common Shares (subject to adjustment as provided in Section 14.04 of this Indenture) per $1,000 principal amount of Notes (subject to the settlement provisions of Section 14.02, the “Conversion Obligation”).

Section 14.02 Conversion Procedure.

(a) Subject to this Section 14.02, upon any conversion of any Note, the Company shall deliver to converting Noteholders, in respect of each $1,000 principal amount of Notes being converted, solely cash, solely Common Shares or a combination of cash and Common Shares (the “Settlement Amount”), at its sole election, as set forth in this Section 14.02.

(i) All conversions after December 15, 2037 will be settled using the same Settlement Method.

(ii) Prior to December 15, 2037, the Company will elect (or be deemed to have elected) the same Settlement Method for all conversions occurring on any given Conversion Date. Except for any conversions that occur on or after December 15, 2037, the Company need not elect the same Settlement Method with respect to conversions that occur on different Trading Days.

(iii) If, in respect of any Conversion Date (or the period beginning on, but excluding, December 15, 2037 and ending on, and including, the Business Day immediately preceding the Maturity Date, as the case may be), the Company elects to deliver a notice (the “Settlement Notice”) of the relevant Settlement Method in respect of such Conversion Date (or such period, as the case may be), the Company, through the Trustee, shall deliver such Settlement Notice to converting Noteholders no later than the second Trading Day immediately following the relevant Conversion Date. Such Settlement Notice shall specify whether the Company shall satisfy its Conversion Obligation by (A) delivering solely Common Shares, (B) paying solely cash or (C) paying and delivering, as the case may be, a combination of cash and Common Shares. In the case of an election to pay and deliver, as the case may be, a combination of cash and Common Shares, the relevant Settlement Notice shall indicate the Specified Dollar Amount. If the Company does not deliver a Settlement Notice, the Company shall be deemed to have elected to deliver a combination of cash and Common Shares in respect of its Conversion Obligation, and the Specified Dollar Amount shall be deemed to be equal to $1,000. If the Company delivers a Settlement Notice electing to pay and deliver, as the case may be, a combination of cash and Common Shares in respect of its Conversion Obligation but does not indicate a Specified Dollar Amount in such Settlement Notice, the Specified Dollar Amount shall be deemed to be equal to $1,000.

(iv) Notwithstanding any other provision described in this Indenture, in the event the Company settles any conversion or any other payment (such as in connection with a Make-Whole Fundamental Change or similar transaction) in Common Shares, but the Company determines, in its judgment, that the Company may not do so with respect to a particular holder or holders due to the rules of the New York Stock Exchange, the Company may instead make all or any part of such settlement to such holder or holders in the form of cash, even though the Company may make such settlement to other holders in Common Shares or a combination of cash and Common Shares that differs from the settlement to such particular holder or holders.

(v) The Settlement Amount in respect of any conversion of Notes shall be computed as follows:

(1) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by delivering solely Common Shares, the Company shall deliver to the converting Noteholder a number of Common Shares equal to (1) the aggregate principal amount of Notes to be converted, divided by $1,000, multiplied by (2) the then-applicable Conversion Rate;

(2) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by paying solely cash, the Company shall pay to the converting Noteholder cash in an amount per $1,000 principal amount of Notes being converted equal to the sum of the Daily Conversion Values for each of the sixty consecutive Trading Days during the related Cash Settlement Averaging Period; and

(3) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by paying and delivering, as the case may be, a combination of cash and Common Shares, if any, the Company shall pay and deliver, as the case may be, in respect of each $1,000 principal amount of Notes being converted, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the sixty consecutive Trading Days during the related Cash Settlement Averaging Period.

(vi) The Company shall also deliver to each converting Noteholder cash in lieu of fractional Common Shares as set forth pursuant to clause (j) below.

(vii) The Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable) shall be determined by the Company promptly following the last day of the Cash Settlement Averaging Period. Promptly after such determination of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash deliverable in lieu of fractional shares (if any), the Company shall notify the Trustee and the Conversion Agent of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash deliverable in lieu of fractional Common Shares. The Trustee and the Conversion Agents shall have no responsibility for any such determination.

(b) Before any holder of a Note shall be entitled to convert the same as set forth above, such holder shall (i) in the case of a Global Note, comply with the procedures of the Depositary in effect at that time and, if required, pay funds equal to interest payable on the next Interest Payment Date to which such holder is not entitled as set forth in Section 14.02(h) and, if required, all transfer or similar taxes, if any, and (ii) in the case of a Note issued in certificated form, (1) complete and manually sign and deliver an irrevocable notice to the Conversion Agent in the form on the reverse of such certificated Note (or a facsimile thereof) (Annex A hereto) (a “Notice of Conversion”) at the office of the Conversion Agent and shall state in writing therein the principal amount of Notes to be converted and the name or names (with addresses) in which such holder wishes the certificate or certificates for any Common Shares, if any, to be delivered upon settlement of the Conversion Obligation to be registered, (2) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the Conversion Agent, (3) if required, pay funds equal to interest payable on the next Interest Payment Date to which such holder is not entitled as set forth in Section 14.02(h), (4) if required, furnish appropriate endorsements and transfer documents, and (5) if required, pay all transfer or similar taxes, if any as set forth in Section 14.02(e). The Trustee (and if different, the relevant Conversion Agent) shall notify the Company of any conversion pursuant to this Article 14 on the date of such conversion. No Notice of Conversion with respect to any Notes may be surrendered by a holder thereof if such holder has also delivered a Repurchase Notice to the Company in respect of such Notes and not validly withdrawn such Repurchase Notice in accordance with Section 15.02 or if such holder has also delivered a Fundamental Change Repurchase Notice to the Company in respect of such Notes and not validly withdrawn such Fundamental Change Repurchase Notice in accordance with Section 15.05.

If more than one Note shall be surrendered for conversion at one time by the same holder, the Conversion Obligation with respect to such Notes, if any, that shall be payable upon conversion shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted thereby) so surrendered.

(c) A Note shall be deemed to have been converted immediately prior to the close of business on the date (the “Conversion Date”) that the holder has complied with the requirements set forth in clause (b). The Company shall pay and deliver, as the case may be, the cash and/or Common Shares due in respect of it Conversion Obligation on the third Trading Day immediately following the relevant Conversion Date, if the Company elects to satisfy the related Conversion Obligation solely in Common Shares, or by the third Trading Day immediately following the last Trading Day of the Cash Settlement Averaging Period, in the case of any other Settlement Method. If any Common Shares are due to converting Noteholders, the Company shall issue or cause to be issued, and deliver to the Conversion Agent or to such Noteholder, or such Noteholder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the number of full Common Shares to which such Noteholder shall be entitled in satisfaction of such Conversion Obligation.

(d) In case any Note shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the holder of the Note so surrendered, without charge to such holder, a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note.

(e) If a holder submits a Note for conversion, the Company shall pay all stamp and other duties, if any, that may be imposed by the United States or any political subdivision thereof or taxing authority thereof or therein with respect to the issuance of Common Shares, if any, upon the conversion. However, the holder

shall pay any such tax that is due because the holder requests any Common Shares to be issued in a name other than the holder’s name or the tax is imposed by any taxing authority outside the United States. The Conversion Agent may refuse to deliver the certificates representing the Common Shares being issued in a name other than the holder’s name until the Trustee receives a sum sufficient to pay any tax that will be due because the shares are to be issued in a name other than the holder’s name. Nothing herein shall preclude any tax withholding required by law or regulations.

(f) Except as provided in Section 14.04, no adjustment shall be made for dividends on any shares issued upon the conversion of any Note as provided in this Article.

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

(h) Upon conversion, a Noteholder shall not receive any separate cash payment for accrued and unpaid interest and Additional Interest, if any, except as set forth below. The Company’s settlement of the Conversion Obligations as described above shall be deemed to satisfy its obligation to pay the principal amount of the Note and accrued and unpaid interest and Additional Interest, if any, to, but not including, the Conversion Date. As a result, accrued and unpaid interest and Additional Interest, if any, to, but not including, the Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Notwithstanding the preceding sentence, if Notes are converted after the close of business on an Interest Record Date, but prior to the opening of business on the corresponding Interest Payment Date, holders of such Notes as of the close of business on the Interest Record Date will receive the interest and Additional Interest, if any, payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period from the close of business on any Interest Record Date to the opening of business on the corresponding Interest Payment Date must be accompanied by payment of an amount equal to the interest and Additional Interest, if any, payable on the Notes so converted; provided, however, that no such payment shall be required (1) if the Company has called the Notes for redemption, (2) if the Company has specified a Fundamental Change Repurchase Date that is after an Interest Record Date but on or prior to the corresponding Interest Payment Date, (3) to the extent of any Defaulted Interest, if any, existing at the time of conversion with respect to such Note or (4) if the Notes are surrendered for conversion after the close of business on the Interest Record Date immediately preceding the Maturity Date. Except as described above, no payment or adjustment will be made for accrued and unpaid interest and Additional Interest, if any, on converted Notes.

(i) The Person in whose name the certificate for any Common Shares delivered upon conversion is registered shall be treated as a stockholder of record as of the close of business on the relevant Conversion Date (if the Company elects to satisfy the related Conversion Obligation solely in Common Shares) or the last Trading Day of the related Cash Settlement Averaging Period (in the case of any other Settlement Method), as the case may be; provided, however, if such Conversion Date or such last Trading Day of the Cash Settlement Averaging Period occurs on any date when the stock transfer books of the Company shall be closed, such occurrence shall not be effective to constitute the Person or Persons entitled to receive any such Common Shares due upon conversion as the record holder or holders of such Common Shares on such date, but such occurrence shall be effective to constitute the Person or Persons entitled to receive such Common Shares as the record holder or holders thereof for all purposes at the close of business on the next succeeding day on which such stock transfer books are open. Upon conversion of Notes, such Person shall no longer be a Noteholder.

(j) For each Note surrendered for conversion, if the Company has elected to deliver a combination of cash and Common Shares in respect of its Conversion Obligation, the number of full shares that shall be issued upon conversion thereof shall be computed on the basis of the aggregate Daily Settlement Amounts for the applicable Cash Settlement Averaging Period and any fractional shares remaining after such computation shall be paid in cash. 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 issued upon conversion thereof shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof) so surrendered. The Company shall not issue fractional

Common Shares upon conversion of Notes. Instead, the Company shall pay cash in lieu of fractional shares based on the VWAP on the relevant Conversion Date (if the Company elects to satisfy its Conversion Obligation solely in Common Shares) or based on the VWAP on the last Trading Day of the relevant Cash Settlement Averaging Period (in the case of any other Settlement Method).

Section 14.03 Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental Changes.

(a) Notwithstanding anything herein to the contrary, if the Effective Date of a Make-Whole Fundamental Change occurs on or prior to July 1, 2013, the Conversion Rate applicable to each Note that is surrendered for conversion, in accordance with this Article 14, at any time from, and including, the effective date of such Make-Whole Fundamental Change until, and including, the close of business on the Business Day immediately prior to the related Fundamental Change Repurchase Date (or if the Make-Whole Fundamental Change is not also a Fundamental Change, the Last Make-Whole Date) corresponding to such Make-Whole Fundamental Change shall be increased to an amount equal to the Conversion Rate that would, but for this Section 14.03, otherwise apply to such Note pursuant to this Article 14, plus an amount equal to the Make-Whole Conversion Rate Adjustment.

As used herein, “Make-Whole Conversion Rate Adjustment” shall mean, with respect to a Make-Whole Fundamental Change, the amount set forth in the following table that corresponds to the date such Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”) and the Share Price for such Make-Whole Fundamental Change, all as determined by the Company:

provided, however, that:

(i) if the actual Share Price of such Make-Whole Fundamental Change is between two Share Prices listed in the table above under the column titled “Common Share Price,” or if the actual Effective Date of such Make-Whole Fundamental Change is between two Effective Dates listed in the table above in the row immediately below the title “Effective Date,” then the Make-Whole Conversion Rate Adjustment for such Make-Whole Fundamental Change shall be determined by the Company by a straight-line interpolation between the Make-Whole Conversion Rate Adjustment set forth for such higher and lower Share Prices, or for such earlier and later Effective Dates based on a 365-day year, as applicable;

(ii) if the actual Share Price of such Make-Whole Fundamental Change is greater than $150.00 per share (subject to adjustment in the same manner as the Share Price as provided in clause (iii) below), or if the actual Share Price of such Make-Whole Fundamental Change is less than $7.53 per share (subject to adjustment in the same manner as the Share Price as provided in clause (iii) below), then the Make-Whole Conversion Rate Adjustment shall be equal to zero and this Section 14.03 shall not require the Company to increase the Conversion Rate with respect to such Make-Whole Fundamental Change;

(iii) if an event occurs that requires, pursuant to this Article 14 (other than solely pursuant to this Section 14.03), an adjustment to the Conversion Rate, then, on the date and at the time such adjustment is so required to be made, each price set forth in the table above under the column titled “Common Share Price” shall be deemed to be adjusted so that such Share Price, at and after such time, shall be equal to the product of (1) such Share Price as in effect immediately before such adjustment to such Share Price and (2) a fraction whose numerator is the Conversion Rate in effect immediately before such adjustment to the Conversion Rate and whose denominator is the Conversion Rate to be in effect, in accordance with this Article 14, immediately after such adjustment to the Conversion Rate;

(iv) each Make-Whole Conversion Rate Adjustment set forth in the table above shall be adjusted in the same manner in which, and for the same events for which, the Conversion Rate is to be adjusted pursuant to Section 14.04; and

(v) in no event will the total number of Common Shares issuable upon conversion of the Notes exceed 132.8021 per $1,000 principal amount of Notes, subject to adjustment in the same manner as the Conversion Rate pursuant to Section 14.04.

(b) As soon as practicable after the Company determines the anticipated Effective Date of any proposed Make-Whole Fundamental Change, the Company shall mail to each Noteholder, the Trustee and the Conversion Agent written notice of, and shall issue a press release indicating, and publicly announce, through a public medium that is customary for such announcements, and publish on the Company’s website, the anticipated effective date of such proposed Make-Whole Fundamental Change and such notice must occur, to the extent practicable, at least twenty Business Days prior to such anticipated Effective Date. Each such press release notice, announcement and publication shall also state that in connection with such Make-Whole Fundamental Change, the Company shall increase, in accordance herewith, the Conversion Rate applicable to Notes entitled as provided herein to such increase (along with a description of how such increase shall be calculated and the time periods during which Notes must be surrendered in order to be entitled to such increase as specified below). No later than the actual Effective Date of each Make-Whole Fundamental Change, the Company shall mail to each Noteholder, the Trustee and the Conversion Agent written notice of, and shall issue a press release indicating, and publicly announce, through a public medium that is customary for such announcements, and publish on the Company’s website, such Effective Date and the amount by which the Conversion Rate has been so increased and the last day on which the Notes must be effectively converted in order for holders to receive the Make-Whole Conversion Rate Adjustment upon conversion. Such last day shall be, in the case of a Make-Whole Fundamental Change that is also a Fundamental Change, the corresponding Fundamental Change Repurchase Date and, in the case of a Make-Whole Fundamental Change that is not also a Fundamental Change, a day (the “Last Make-Whole Date”) that is at least 30 days after the effective date of such Make-Whole Fundamental Change and is specified by the Company in the notice announcing such effective date.

(c) If a “person” or “group” within the meaning of Section 13(d) of the Exchange Act, files a Schedule TO or any schedule, form or report under the Exchange Act disclosing that such person or group has become the direct or indirect ultimate “beneficial owner”, as defined in Rule 13d-3 under the Exchange Act, of Common Shares representing more than 50% of the voting power of the Company’s Common Shares and a Make-Whole Fundamental Change does not occur, then, until such time as a Make-Whole Fundamental Change occurs, or until such person or group ceases to beneficially own, directly or indirectly, more than 50% of the voting power of the Company’s Common shares, the Company shall be required to increase the annual interest rate on the Notes by 1.0%. Notwithstanding the foregoing, the interest rate shall increase only to the extent the Current Market Price of

the Company’s Common Shares over the ten consecutive Trading Days preceding such filing does not exceed $150.00 (subject to adjustment in the same manner as the Share Price as provided in Section 14.03(a)(iii)). The Company shall notify the holders of such filing and the new annual interest rate as soon as practicable after such filing has occurred.

Nothing in this Section 14.03 shall prevent an adjustment to the Conversion Rate pursuant to Section 14.04 in respect of a Make-Whole Fundamental Change.

Section 14.04 Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time, without duplication, by the Company as follows:

(a) If the Company issues Common Shares as a dividend, bonus shares or distribution to all holders of the outstanding Common Shares on Common Shares, or if the Company effects a subdivision or combination of Common Shares, the Conversion Rate will be adjusted based on the following formula:

CR¹ = CR₀ x (OS¹ ÷ OS₀)


where

CR₀	=	the Conversion Rate in effect at the close of business on the Record Date;

CR¹	=	the Conversion Rate in effect immediately after the Record Date;

OS₀	=	the number of Common Shares issued and outstanding at the close of business on the Record Date prior to giving effect to such event; and

OS¹	=	the number of Common Shares that would be issued and outstanding immediately after, and solely as a result of, such event.

(b) In case the Company shall issue to all holders of Common Shares of rights or warrants (including convertible securities) entitling them for a period expiring 60 calendar days or less from the date of issuance of such rights or warrants to purchase Common Shares at an exercise price per share less than (or having a conversion price per share less than) the Current Market Price of the Common Shares as of the Record Date, the Conversion Rate will be adjusted based on the following formula

CR¹ = CR₀ x [(OS₀ + X) ÷ (OS₀ + Y)]


where

CR₀	=	the Conversion Rate in effect at the close of business on the Record Date;

CR¹	=	the Conversion Rate in effect immediately after the Record Date;

OS₀	=	the number of Common Shares issued and outstanding at the close of business on the Record Date;

X	=	the total number of Common Shares issuable pursuant to such rights or warrants (or upon conversion of such securities); and

Y	=	the aggregate price payable to exercise such rights or warrants (or the conversion price for such securities paid upon conversion) divided by the average of the VWAP of the Common Shares over each of the ten consecutive Trading Days prior to the business day immediately preceding the announcement of the issuance of such rights.

However, the Conversion Rate shall be readjusted to the extent that any such rights or warrants are not exercised prior to their expiration; provided that such readjustment shall not have any effect on Notes that had been converted prior to such readjustment or on the Common Shares issued pursuant thereto, and such readjustment shall apply only to such Notes that remain outstanding at the time of such readjustment.

(c) In case the Company shall make a dividend or other distribution to all holders of Common Shares of the Company’s Share Capital (other than Common Shares), rights or warrants (including convertible securities) to acquire the Company’s Share Capital, evidences of indebtedness of the Company or assets of the Company (excluding any dividend, distribution or issuance covered by Section 14.04(a) or (b) or Section 14.04(d) or (e)) (any of such Share Capital, indebtedness, or other asset, then, in each such case the Conversion Rate shall be adjusted based on the following formula:

CR¹ = CR₀ x [SP₀ ÷ (SP₀ - FMV)]


where

CR₀	=	the Conversion Rate in effect at the close of business on the Record Date;

CR¹	=	the Conversion Rate in effect immediately after the Record Date;

SP₀	=	the Current Market Price of the Common Shares as of the Record Date; and

FMV	=	the fair market value (as determined by the Board of Directors) on the Record Date of the Share Capital, rights or warrants, evidences of indebtedness or assets so distributed, expressed as an amount per Common Share.

However, if the transaction that gives rise to an adjustment pursuant to this Section 14.04(c) is one pursuant to which the payment of a dividend, bonus shares or other distribution on Common Shares consists of Share Capital of, or similar equity interests in, a subsidiary or other business unit of the Company (a “Spin-Off”), or consists of any other securities, that are, or, when issued, will be, traded on a securities exchange or quoted on a quotations facility in the U.S. or elsewhere, then the Conversion Rate will instead be adjusted based on the following formula:

CR¹ = CR₀ x [(FMV₀ + MP₀) ÷ MP₀]


where

CR₀	=	the Conversion Rate in effect at the close of business on the Record Date;

CR¹	=	the Conversion Rate in effect immediately after the Record Date;

FMV₀	=	the average of the VWAP of the Share Capital or similar equity interests distributed to holders of Common Shares applicable to one of the Company’s Common Shares over each of the ten consecutive Trading Days commencing on and including the third Trading Day after the date on which “ex-distribution trading” commences for such Share Capital or similar equity interest on the principal exchange or other market on which they are then listed or quoted; and

MP₀	=	the average of the VWAP of the Common Shares over each of the ten consecutive Trading Days commencing on and including the third Trading Day after the date on which “ex-distribution trading” commences for such dividend or distribution on the principal exchange or other market on which the Common Shares are then listed or quoted.

(d) If the Company makes a distribution consisting exclusively of cash to all holders of Common Shares, excluding (i) any cash that is distributed as part of a distribution referred to in Section 14.04(c) and (ii) any consideration payable in connection with a tender or exchange offer made by the Company or any of its subsidiaries referred to in Section 14.04(e), the Conversion Rate shall be adjusted based on the following formula:

CR¹ = CR₀ x [SP₀ ÷ (SP₀ – C)]


where

CR₀	=	the Conversion Rate in effect at the close of business on the Record Date;

CR¹	=	the Conversion Rate in effect immediately after the Record Date;

SP₀	=	the Current Market Price of the Common Shares as of the Record Date; and

C	=	the amount in cash per share the Company distributes to holders of its Common Shares, excluding any cash described in clauses (i) and (ii) of Section 14.04(d).

(e) If the Company or one or more of its Subsidiaries makes purchases of Common Shares pursuant to a tender offer or exchange offer by the Company or one or more of its Subsidiaries for Common Shares to the extent (as determined by the Board of Directors) that the cash and value of any other consideration included in the payment per Common Share validly tendered or exchanged exceeds the VWAP per Common Share on the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer (the “Expiration Date”), the Conversion Rate shall be increased based on the following formula:

CR¹ = CR₀ x [(FMV + (SP¹ x OS¹)) ÷ (SP¹ x OS₀)]


where

CR₀	=	the Conversion Rate in effect at the close of business on the Expiration Date;

CR¹	=	the Conversion Rate in effect immediately after the Expiration Date;

FMV	=	the fair market value (as determined by the Board of Directors), on the Expiration Date, of the aggregate value of all cash and any other consideration paid or payable for Common Shares validly tendered or exchanged and not withdrawn as of the Expiration Date (the “Purchased Shares”);

OS¹	=	the number of Common Shares issued and outstanding as of the last time tenders or exchanges may be made pursuant to such tender or exchange offer (the “Expiration Time”) less any purchased shares;

OS₀	=	the number of Common Shares issued and outstanding at the Expiration Time, including any Purchased Shares; and

SP¹	=	the average of the VWAP of the Common Shares over each of the ten consecutive Trading Days commencing with the Trading Day immediately after the Expiration Date.

(f) The term “Record Date” means, for the purpose of Section 14.04, with respect to any dividend, bonus shares, distribution or other transaction or event in which the holders of Common Shares have the right to receive any cash, securities or other property or in which Common Shares (or other applicable security) are exchanged for or converted into any combination of cash, securities or other property, the date fixed for determination of holders of Common Shares entitled to receive such cash, securities or other property (whether such date is fixed by our board of directors or by statute, contract or otherwise).

(g) Except as stated herein, the Company shall not adjust the Conversion Rate for the issuance of shares of its Common Shares or any securities convertible into or exchangeable for shares of its Common Shares or the right to purchase shares of its Common Shares or such convertible or exchangeable securities. In no event shall the Company adjust the Conversion Rate to the extent that the adjustment would reduce the Conversion Price below the par value per Common Share.

(h) Notwithstanding this Section 14.04 or any other provision of this Indenture or the Notes, if any Conversion Rate adjustment becomes effective, or any Ex-Dividend Date for any issuance, dividend or distribution (relating to a required Conversion Rate adjustment) occurs, during the period beginning on, and including, the open of business on a Conversion Date and ending on, and including, (x) the close of business on the third Trading Day immediately following the relevant Conversion Date (if the Company elects to satisfy the related Conversion Obligation solely in Common Shares) or (y) the close of business on the last Trading Day of a related Cash Settlement Averaging Period (in the case of any other Settlement Method), the Board of Directors shall make adjustments to the Conversion Rate and the amount of cash or number of Common Shares issuable upon conversion of the Notes, as the case may be, as is be necessary or appropriate to effect the intent of this Section 14.04 and the other provisions of Article 14 and to avoid unjust or inequitable results, as determined in good faith by the Board of Directors. Any adjustment made pursuant to this Section 14.04(h) shall apply in lieu of the adjustment or other term that would otherwise be applicable.

(i) In addition to those required by clauses (a), (b), (c), (d) and (e) of this Section 14.04, and to the extent permitted by applicable law and subject to the applicable rules of the New York Stock Exchange, the Company from time to time may increase the Conversion Rate by any amount for a period of at least twenty Business Days if the Board of Directors determines that such increase would be in the Company’s best interest. In addition, the Company may also (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to holders of Common Shares or rights to purchase Common Shares in connection with any dividend or distribution of shares (or rights to acquire shares) or similar event. Whenever the Conversion Rate is increased pursuant to the preceding sentence, the Company shall mail to the holder of each Note at its last address appearing on the Note Register provided for in Section 2.06 a notice of the increase at least fifteen days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect.

(j) The applicable Conversion Rate will not be adjusted:

(i) upon the issuance of any Common Shares pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of the Common Shares under any plan;

(ii) upon the issuance of any Common Shares or options or rights to purchase or acquire those shares pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by the Company or any of the Company’s Subsidiaries;

(iii) upon the issuance of any Common Shares pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in clause (ii) of this subsection and outstanding as of the date the Notes were first issued;

(iv) for a change in the par value of the Common Shares;

(v) for accrued and unpaid interest, including Additional Interest, if any; or

(vi) for any transactions described in this Section 14.04 if Noteholders participate (as a result of holding the Notes, and at the same time as holders of Common Shares participate) in such transactions as if such Noteholders held a number of Common Shares equal to the Conversion Rate at the time such adjustment would be required, multiplied by the principal amount (expressed in thousands) of Notes held by such Noteholder, without having to convert their Notes.

(k) No adjustment in the Conversion Rate shall be required unless such adjustment would require an increase or decrease of at least one percent; provided, however, that any such minor adjustments that are not required to be made will be carried forward and taken into account in any subsequent adjustment, and provided further that any such adjustment of less than one percent that has not been made shall be made upon (x) the date of a Make-Whole Fundamental Change and (y) any Conversion Date. All calculations and other determinations under this Article 14 shall be made by the Company and shall be made to the nearest one-ten thousandth (1/10,000) of a share.

(l) Whenever the Conversion Rate is adjusted as herein provided, the Company 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 without inquiry that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company 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 2.06 of this Indenture, within ten days of the effective date of such adjustment. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

(m) For purposes of this Section 14.04, the number of Common Shares at any time outstanding shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of Common Shares. The Company will not pay any dividend or make any distribution on Common Shares held in the treasury of the Company.

Section 14.05 Shares to Be Fully Paid. The Company shall provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient Common Shares to provide for conversion of the Notes from time to time as such Notes are presented for conversion.

Section 14.06 Effect of Reclassification, Consolidation, Merger or Sale. Upon the occurrence of (i) any reclassification or change of the outstanding Common Shares (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 split, subdivision or combination covered by Section 14.04(a)), (ii) any consolidation, merger, amalgamation, scheme of arrangement or combination involving the Company, or (iii) any sale or conveyance of all or substantially all of the property and assets of the Company to any other Person, in each case as a result of which holders of Common Shares shall be entitled to receive cash, securities or other property or assets with respect to or in exchange for such Common Shares (any such event a “Merger Event”), then:

(a) the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture if such supplemental indenture is then required to so comply) permitted under Section 11.01(f) providing for the conversion and settlement of the Notes as set forth in this Indenture. Such supplemental indenture shall provide for adjustments that shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article 14. If, in the case of any Merger Event, the Reference Property includes shares of stock or other securities and assets of a corporation other than the successor or purchasing corporation, as the case may be, in such reclassification, change, consolidation, merger, amalgamation, scheme of arrangement, combination, sale or conveyance, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the holders of the Notes as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including to the extent required by the Board of Directors and practicable the provisions providing for the repurchase rights set forth in Article 15 herein.

In the event the Company shall execute a supplemental indenture pursuant to this Section 14.06, the Company shall promptly file with the Trustee an Officers’ Certificate briefly stating the reasons therefore, the kind or amount of cash, securities or property or asset that will comprise the Reference Property after any such

Merger Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly mail notice thereof to all Noteholders. The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Noteholder, at its address appearing on the Note Register provided for in this Indenture, within twenty days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

(b) Notwithstanding the provisions of Section 14.02(a), and subject to the provisions of Section 14.01 and Section 14.03, at and after the effective time of such Merger Event, (i) the right to convert each $1,000 principal amount of Notes into cash, Common Shares or a combination of cash and Common Shares at the Company’s election as set forth in Section 14.02 will be changed to a right to convert such Note into cash, the kind and amount of shares of stock, securities or other property or assets (including cash or any combination thereof) that a holder of a number of Common Shares equal to the Conversion Rate immediately prior to such transaction would have owned or been entitled to receive (the “Reference Property”) or a combination of cash and Reference Property at the Company’s election and (ii) the related Conversion Obligation shall be settled as set forth under clause (c) below. The Company shall not become a party to any Merger Event unless its terms are consistent with this Section 14.06. None of the foregoing provisions shall affect the right of a holder of Notes to convert its Notes into cash, Common Shares or a combination of cash and Common Shares, as applicable, as set forth in Section 14.01 and Section 14.02 prior to the effective date of such Merger Event.

(c) With respect to each $1,000 principal amount of Notes surrendered for conversion after the effective date of any such Merger Event, the Company’s Conversion Obligation shall be settled in cash or units of Reference Property, at the Company’s election, in accordance with Section 14.02(a) as follows:

(i) (A) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by delivering solely Reference Property, the Company shall deliver to the converting Noteholder a number of units of Reference Property (each such unit comprised of the kind and amount of shares of stock, securities or other property or assets (including cash or any combination thereof) that a holder of one share of Common Shares immediately prior to such Merger Event would have owned or been entitled to receive based on the Weighted Average Consideration) equal to (1) the aggregate principal amount of Notes to be converted, divided by $1,000, multiplied by (2) the then-applicable Conversion Rate; (B) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by paying solely cash, the Company shall pay to the converting Noteholder cash in an amount per $1,000 principal amount of Notes being converted equal to the sum of the Daily Conversion Values for each of the sixty consecutive Trading Days during the related Cash Settlement Averaging Period, such Daily Conversion Values determined as if the reference to “the VWAP of the Common Shares” in the definition thereof were instead a reference to “the VWAP of a unit of Reference Property comprised of the kind and amount of shares of stock, securities or other property or assets (including cash or any combination thereof) that a holder of one share of Common Shares immediately prior to such Merger Event would have owned or been entitled to receive based on the Weighted Average Consideration”; and (C) if the Company elects to satisfy its Conversion Obligation by paying or delivering, as the case may be, of a combination of cash and Reference Property, the Company shall pay and deliver, as the case may be, in respect of each $1,000 principal amount of Notes being converted, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the sixty consecutive Trading Days during the Cash Settlement Averaging Period for such Note, such Daily Settlement Values determined as if the reference to “the VWAP of the Common Shares” in the definition of Daily Conversion Value and Daily Share Amount were instead a reference to “the VWAP of a unit of Reference Property comprised of the kind and amount of shares of stock, securities or other property or assets (including cash or any combination thereof) that a holder of one share of Common Shares immediately prior to such Merger Event would have owned or been entitled to receive based on the Weighted Average Consideration.”

(ii) The Company will deliver the cash in lieu of fractional units of Reference Property as set forth pursuant to Section 14.02(j) (provided that the amount of such cash shall be determined as if references in such Section to “the VWAP” were instead a reference to “the VWAP of a unit of Reference Property composed of the kind and amount of shares of stock, securities or other property

or assets (including cash or any combination thereof) that a holder of one share of Common Shares immediately prior to such Merger Event would have owned or been entitled to receive based on the Weighted Average Consideration”).

(iii) The Daily Settlement Amounts (if applicable) and Daily Conversion Values (if applicable) shall be determined by the Company promptly following the last day of the Cash Settlement Averaging Period.

(iv) For purposes of this Section 14.06, the “Weighted Average Consideration” shall mean the weighted average of the types and amounts of consideration received by the holders of the Common Shares entitled to receive cash, securities or other property or assets with respect to or in exchange for such Common Shares in any Merger Event who affirmatively make such an election.

(v) The Company shall notify the holders of the Weighted Average Consideration as soon as practicable after the Weighted Average Consideration is determined.

(d) The above provisions of this Section shall similarly apply to successive Merger Events.

Section 14.07 Certain Covenants.

(a) The Company shall provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient Common Shares for the conversion of Notes from time to time as such Notes are presented for conversion.

(b) The Company covenants that all Common Shares issued upon conversion of Notes will be fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof.

(c) The Company covenants that, if any Common Shares to be provided for the purpose of conversion of Notes hereunder require registration with or approval of any governmental authority under any federal or state law (including but not limited to, the shareholder approval rules of The New York Stock Exchange) before such shares may be validly issued upon conversion, the Company will, to the extent then permitted by the rules and interpretations of the Commission, secure such registration or approval, as the case may be.

(d) 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 Common Shares issuable upon conversion of the Notes, the Company shall take all corporate action which may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue Common Shares at such adjusted Conversion Rate.

(e) The Company further covenants that if at any time the Common Shares shall be listed on any national securities exchange or automated quotation system the Company will list and keep listed, so long as the Common Shares shall be so listed on such exchange or automated quotation system, any Common Shares issuable upon conversion of the Notes.

Section 14.08 Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any Noteholder to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) 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 Common Shares, or of any securities, property or cash that 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 Company

to issue, transfer or deliver any Common Shares 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 Company contained in this Article. 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 14.06 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Noteholders upon the conversion of their Notes after any event referred to in such Section 14.06 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 8.01, may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto.

Section 14.09 Notice to Holders Prior to Certain Actions. In case:

(a) the Company shall declare a dividend (or any other distribution) on its Common Shares that would require an adjustment in the Conversion Rate pursuant to Section 14.04; or

(b) the Company shall authorize the granting to all of the holders of its Common Shares of rights, options or warrants to subscribe for or purchase any share of any class or any other rights, options or warrants; or

(c) of any reclassification of the Common Shares of the Company (other than a subdivision or combination of its outstanding Common Shares, 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 or merger to which the Company is a party and for which approval of any stockholders of the Company is required, or of the sale or transfer of all or substantially all of the assets of the Company; or

(d) of the voluntary or involuntary dissolution, liquidation or winding-up of the Company; the Company shall cause to be filed with the Trustee and to be mailed to each Noteholder at its address appearing on the Note Register, provided for in Section 2.06 of this Indenture, as promptly as possible but in any event at least twenty days prior to the applicable date hereinafter specified, a notice stating (i) the date on which a record is to be taken for the purpose of such dividend, distribution or rights, options or warrants, or, if a record is not to be taken, the date as of which the holders of Common Shares of record to be entitled to such dividend, distribution or rights are to be determined, or (ii) 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 Shares of record shall be entitled to exchange their Common Shares 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 14.10 Stockholder Rights Plans. To the extent that the Company has a stockholder rights plan or other “poison pill” in effect upon conversion of the Notes, each share of Common Shares, if any, issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Shares issued upon such conversion shall bear such legends, if any, in each case as may be provided by the terms of any such stockholder rights plan or poison pill, as the same may be amended from time to time. If prior to the time of conversion, however, the rights have separated from the Common Shares 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 Shares, if any, issuable upon conversion of the Notes, the Conversion Rate will be adjusted at the time of separation as if the Company has distributed to all holders of Common Shares, Share Capital of the Company, rights or warrants to acquire Share Capital of the Company, evidences of indebtedness or other of its assets or property as provided in Section 14.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights.

ARTICLE 15

REPURCHASE OF NOTES AT OPTION OF HOLDERS

Section 15.01 Repurchase of Notes by the Company at Option of the Holder.

(a) On July 1, 2013, July 1, 2018, July 1 2023, July 1, 2028 and July 1, 2033 (each, a “Repurchase Date”), each holder shall have the option to require the Company to repurchase Notes for which that holder has properly delivered and not withdrawn a written Repurchase Notice (as described below) at a repurchase price in cash equal to 100% of the principal amount of those Notes, plus accrued and unpaid interest and accrued and unpaid Additional Interest, if any, on those Notes, to, but not including, such Repurchase Date (the “Repurchase Price”); provided that, if a Repurchase Date is on a date that is after an Interest Record Date and on or prior to the corresponding Interest Payment Date, the Repurchase Price shall be 100% of the principal amount of the Notes repurchased but shall not include accrued and unpaid interest and Additional Interest, if any. Instead, the Company shall pay such accrued and unpaid interest and Additional Interest, if any, on the Interest Payment Date, to the holder of Record on the corresponding Interest Record Date. At least twenty Business Days prior to any Repurchase Date, the Company shall mail a notice (the “Repurchase Company Notice”) by electronic transmission or first-class mail, postage prepaid, to the Trustee, the Paying Agent and the Conversion Agent and to each holder (and to beneficial owners if required by applicable law). Simultaneously with the providing of such notice, the Company shall also publish a notice containing the information set forth in the Repurchase Company Notice in a newspaper of general circulation in The City of New York or publish such information on the Company’s website or through such other public medium as the Company may use at that time. The Repurchase Company Notice shall include a form of Repurchase Notice to be completed by a holder and shall state:

(i) the Repurchase Price;

(ii) the Repurchase Date;

(iii) the name and address of the Paying Agent and the Conversion Agent, if applicable;

(iv) briefly, the conversion rights, if any, that exist at the date of the Repurchase Company Notice or as a result of the Repurchase Company Notice with respect to the Notes;

(v) if applicable, the applicable Conversion Rate, any adjustments to the applicable Conversion Rate;

(vi) if applicable, that the Notes with respect to which a Repurchase Notice has been delivered by a holder may be converted only if the holder withdraws the Repurchase Notice in accordance with the terms of the Indenture;

(vii) that the holder must exercise the repurchase right on or prior to the close of business on the Business Day immediately preceding the Repurchase Date (the “Repurchase Expiration Time”);

(viii) that the Repurchase Price for any Note as to which a Repurchase Notice has been given and not withdrawn shall be paid promptly following the later of the Business Day immediately following the Repurchase Date and the time of surrender of such Note as described in clause (xi) below;

(ix) the procedures the holder must follow to exercise its right to require the Company to repurchase such holder’s Notes under this Section 15.01 and a brief description of that right;

(x) the procedures for withdrawing a Repurchase Notice;

(xi) that Notes must be surrendered to the Paying Agent (by effecting book-entry transfer of the Notes or delivering Notes in certificated form, together with necessary endorsements, as the case may be) to collect payment;

(xii) that, unless the Company defaults in making payment on Notes for which a Repurchase Notice has been submitted, interest or Additional Interest, if any, on such Notes shall cease to accrue from and after the Repurchase Date; and

(xiii) the CUSIP, “ISIN” or other similar number(s), as the case may be, of the Notes.

At the Company’s request, the Trustee shall give such Repurchase Company Notice to each holder in the Company’s name and at the Company’s expense; provided, however, that, in all cases, the text of such Repurchase Company Notice shall be prepared by the Company.

(b) A holder may exercise its rights specified in Section 15.01(a) upon delivery to the Paying Agent of a duly completed notice of repurchase (a “Repurchase Notice”) in the form set forth on the reverse of the Notes as Annex B during the period beginning at any time from the opening of business on the date that is 20 Business Days prior to a Repurchase Date until the Repurchase Expiration Time, stating:

(i) if Notes in certificated form have been issued, the certificate number(s) of the Notes which the holder shall deliver to be repurchased or, if Notes in certificated form have not been issued for such Note, the Repurchase Notice shall comply with the appropriate Depositary procedures for book-entry transfer;

(ii) the portion of the principal amount of Notes to be repurchased, which must be $1,000 or an integral multiple thereof; and

(iii) that Notes are to be repurchased by the Company pursuant to the applicable provision of the Notes and the Indenture.

The delivery of such Note (together with all necessary endorsements) to the Paying Agent at any time after delivery of the Repurchase Notice at the offices of the Paying Agent shall be a condition to receipt by the holder of the Repurchase Price therefor; provided, however, that such Repurchase Price shall be so paid pursuant to this Section 15.01 only if the Note (together with all necessary endorsements) so delivered to the Paying Agent shall conform in all respects to the description thereof in the related Repurchase Notice.

The Company shall repurchase from the holder thereof, pursuant to this Section 15.01, a portion of a Note, if the principal amount of such portion is $1,000 or an integral 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.

Any repurchase by the Company contemplated pursuant to the provisions of this Section 15.01 shall be consummated by the delivery of the consideration to be received by the holder promptly following the later of the Business Day immediately following a Repurchase Date and the time of delivery of the Note (together with all necessary endorsements or notifications of book-entry transfer).

Notwithstanding anything herein to the contrary, any holder delivering to the Paying Agent the Repurchase Notice contemplated by this Section 15.01 shall have the right to withdraw such Repurchase Notice by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 15.02 below at any time prior to the Repurchase Expiration Time.

The Paying Agent shall promptly notify the Company of the receipt by it of any Repurchase Notice or written notice of withdrawal thereof.

(c) Notwithstanding the foregoing, no Notes may be repurchased by the Company at the option of the holders on a Repurchase Date if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to such Repurchase Date (except in the case of an acceleration resulting form a default by the Company in the payment of the Repurchase Price with respect to such Notes).

(d) In connection with any repurchase, the Company shall:

(i) comply with the provisions of Rule 13e-4, Rule 14e-1 and other tender offer rules under the Exchange Act, if required under the Exchange Act,

(ii) file a Schedule TO or any successor or similar schedule, if required under the Exchange Act, and

(iii) otherwise comply with all applicable federal and state securities laws in connection with any offer by the Company to purchase the Notes.

Section 15.02 Withdrawal of Repurchase Notice. A Repurchase Notice may be withdrawn by means of a written notice of withdrawal delivered to the Corporate Trust Office of the Paying Agent in accordance with this Section 15.02 at any time prior to the close of business on the Business Day immediately preceding a Repurchase Date, specifying:

(i) the certificate number, if any, of the Note in respect of which such notice of withdrawal is being submitted, or the appropriate Depositary information if the Note in respect of which such notice of withdrawal is being submitted is represented by a Global Note,

(ii) the principal amount of the Note with respect to which such notice of withdrawal is being submitted, and

(iii) the principal amount, if any, of such Note that remains subject to the original Repurchase Notice, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000;

provided, however, that if the Notes are not in certificated form, the notice must comply with appropriate procedures of the Depositary.

Section 15.03 Deposit of Repurchase Price.

(a) The Company will deposit with the Trustee (or other Paying Agent appointed by the Company, or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 5.04) on or prior to 10:00 a.m., New York City time, on the applicable Repurchase Date an amount of money sufficient to repurchase all of the Notes to be repurchased at the appropriate Repurchase Price. Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company), payment for Notes surrendered for repurchase (and not withdrawn prior to the Repurchase Expiration Time) will be made promptly following the later of (i) such Repurchase Date with respect to such Note (provided the holder has satisfied the conditions in Section 15.01) and (ii) the time of book-entry transfer or the delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the holder thereof in the manner required by Section 15.01 by mailing checks for the amount payable to the holders of such Notes entitled thereto as they shall appear in the Note Register, provided, however, that payments to the Depositary shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. The Trustee shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Repurchase Price.

(b) If by 10:00 a.m., New York City time, on the applicable Repurchase Date, the Trustee (or other Paying Agent appointed by the Company) holds money sufficient to make payment on all the Notes or portions thereof that are to be repurchased pursuant to Section 15.01, then (i) such Notes will cease to be outstanding, (ii) interest, including Additional Interest, if any, will cease to accrue on such Notes, and (iii) all other rights of the

holders of such Notes will terminate (other than the right to receive the Repurchase Price, and previously accrued but unpaid interest, including Additional Interest, if any, upon delivery of the Notes), whether or not book-entry transfer of the Notes has been made or the Notes have been delivered to the Trustee or Paying Agent.

(c) Upon surrender of a Note that is to be repurchased in part pursuant to Section 15.01, the Company shall execute and the Trustee shall authenticate and deliver to the holder a new Note in an authorized denomination equal in principal amount to the unrepurchased portion of the Note surrendered.

Section 15.04 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, at such holder’s option, to require the Company to repurchase for cash all of such holder’s Notes, or any portion thereof that is an integral multiple of $1,000 principal amount, on the date (the “Fundamental Change Repurchase Date”) specified by the Company that is not less than twenty Business Days and not more than forty-five Business Days after the date of the Fundamental Change Company Notice (as defined below) at a repurchase price equal to 100% of the principal amount thereof, together with accrued and unpaid interest, including accrued and unpaid Additional Interest, if any, thereon to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”), unless the Fundamental Change Repurchase Date is after an Interest Record Date and on or prior to the related Interest Payment Date, in which case interest accrued to the Interest Payment Date will be paid to holders of the Notes as of such Interest Record Date and the Fundamental Change Repurchase Price payable to the holder surrendering the Note for repurchase pursuant to this Section 15.04 shall be equal to 100% of the principal amount of the Notes subject to repurchase. Repurchases of Notes under this Section 15.04 shall be made, at the option of the holder thereof, upon:

(i) delivery to the Paying Agent by a holder of a duly completed notice (the “Fundamental Change Repurchase Notice”) in the form set forth on the reverse of the Note as Annex C thereto on or prior to the Business Day immediately preceding the Fundamental Change Repurchase Date; and

(ii) delivery or book-entry transfer of the Notes to the Paying Agent at any time after delivery of the Fundamental Change Repurchase Notice (together with all necessary endorsements) at the Corporate Trust Office of the Paying Agent in The Borough of Manhattan, such delivery being a condition to receipt by the holder of the Fundamental Change Repurchase Price therefor; provided that, such Fundamental Change Repurchase Price shall be so paid pursuant to this Section 15.04 only if the Note so delivered to the Paying Agent shall conform in all respects to the description thereof in the related Fundamental Change Repurchase Notice.

The Fundamental Change Repurchase Notice shall state:

(1) if certificated, the certificate numbers of Notes to be delivered for repurchase or the appropriate Depository information if the Note in respect of which such notice is being submitted is represented by a Global Note;

(2) the portion of the principal amount of Notes to be repurchased, which must be $1,000 or an integral multiple thereof; and

(3) that the Notes are to be repurchased by the Company pursuant to the applicable provisions of the Notes and the Indenture;

provided, however, that if the Notes are not in certificated form, the Fundamental Change Repurchase Notice must comply with appropriate Depositary procedures.

Any repurchase by the Company contemplated pursuant to the provisions of this Section 15.04 shall be consummated by the payment of the Fundamental Change Repurchase Price promptly following the later of the Fundamental Change Repurchase Date and the time of the book-entry transfer or delivery of the Note as described in Section 15.06(a).

Notwithstanding anything herein to the contrary, any holder delivering to the Paying Agent the Fundamental Change Repurchase Notice contemplated by this Section 15.04 shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 15.05 below.

The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal thereof.

(b) On or before the twentieth day after the occurrence of the effective date of a Fundamental Change, the Company shall send or caused to be sent by electronic transmission or by first-class mail, postage prepaid, to all holders of record of the Notes (and to beneficial owners if required by applicable law) a notice (the “Fundamental Change Company Notice”) of the occurrence of the effective date of the Fundamental Change and of the repurchase right at the option of the holders arising as a result thereof. The Company shall also deliver a copy of the Fundamental Change Company Notice to the Trustee, the Paying Agent and the Conversion Agent within five Business Days after the effective date of the Fundamental Change. Simultaneously with the providing of such notice, the Company shall also publish a notice containing the information set forth in the Fundamental Change Company Notice in a newspaper of general circulation in The City of New York or publish such information on the Company’s website or through such other public medium as the Company may use at that time. Each Fundamental Change Company Notice shall specify:

(xi) the procedures that holders must follow to require the Company to repurchase their Notes.

No failure of the Company 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 15.04.

(c) Notwithstanding the foregoing, no Notes may be repurchased by the Company at the option of the holders upon a Fundamental Change if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to the Fundamental Change Repurchase Date (except in the case of an acceleration resulting from a default by the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes).

(ii) the principal amount of the Note with respect to which such notice of withdrawal is being submitted, and

(iii) the principal amount, if any, of such Note that remains subject to the original Fundamental Change Repurchase Notice, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000;

provided, however, that if the Notes are not in certificated form, the notice must comply with appropriate procedures of the Depositary.

Section 15.06 Deposit of Fundamental Change Repurchase Price.

(a) The Company will deposit with the Trustee (or other Paying Agent appointed by the Company, or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 5.04) on or prior to 10:00 a.m., New York City time, on the Fundamental Change Repurchase Date an amount of money sufficient to repurchase all of the Notes to be repurchased at the appropriate Fundamental Change Repurchase Price. Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company), payment for Notes surrendered for repurchase (and not withdrawn prior to the Fundamental Change Expiration Time) will be made promptly following the later of (i) the Fundamental Change Repurchase Date with respect to such Note (provided the holder has satisfied the conditions in Section 15.04) and (ii) the time of book-entry transfer or the delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the holder thereof in the manner required by Section 15.04 by mailing checks for the amount payable to the holders of

such Notes entitled thereto as they shall appear in the Note Register, provided, however, that payments to the Depositary shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. The Trustee shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Fundamental Change Repurchase Price.

(c) Upon surrender of a Note that is to be repurchased in part pursuant to 15.04, the Company shall execute and the Trustee shall authenticate and deliver to the holder a new Note in an authorized denomination equal in principal amount to the unrepurchased portion of the Note surrendered.

ADDITIONAL AMOUNTS

Section 16.01 Additional Amounts.

With respect to any payments made by the Company, all such payments under, or with respect to, the Notes will be made free and clear of, and without withholding or deduction for or on account of, any present or future tax, duty, levy, impost, assessment or other governmental charge, including penalties, interest and other liabilities related thereto (“Taxes”), imposed or levied by or on behalf of Bermuda or any other jurisdiction in which the Company is engaged in business, resident for tax purposes or generally subject to tax on a net income basis or through which any such payment is made or any political subdivision or taxing authority of or in any of the foregoing (“Taxing Jurisdiction”), unless we are required to withhold or deduct taxes by law or by the official interpretation or administration thereof.

If the Company is so required to withhold or deduct any amount for, or on account of, such taxes from any payment made under or with respect to the Notes, the Company will pay such additional amounts (“Additional Amounts”), as may be necessary so that the net amount received by each holder and beneficial owner of the Notes (including Additional Amounts) after such withholding or deduction will not be less than the amount such holder or beneficial owner would have received if such Taxes had not been required to be withheld or deducted; provided, however, that Additional Amounts will not be payable with respect to a payment made to a holder or beneficial owner of a Note:

(i) to the extent that such Taxes would not have been so imposed but for the existence of any present or former connection between such holder or beneficial owner (or between a fiduciary, settlor, beneficiary, member or shareholder of, or possessor of a power over, such holder or beneficial owner, if such holder or beneficial owner is an estate, trust, partnership or corporation) and the relevant Taxing Jurisdiction (other than the mere receipt of such payment, acquisition, ownership or disposition (including conversion) of such Note, or enforcement of, or exercise of rights under, such Note or this Indenture);

(ii) except as otherwise provided in this Indenture, with respect to any estate, inheritance, gift, sales, excise, transfer or personal property taxes or other similar taxes imposed with respect to such Note;

(iii) to the extent that such Taxes would not have been so imposed if the holder or beneficial owner of the Note had made a declaration of non-residence or any other claim or filing for exemption to which it is entitled if (x) the making of such declaration or other claim or filing for exemption is required by the applicable law of the relevant taxing jurisdiction as a precondition to exemption from, or reduction in, such Taxes and (y) at least 60 days prior to the first payment date with respect to which such declaration of non-residence or other claim or filing for exemption is required under the applicable law of the relevant taxing jurisdiction, the relevant holder at that time has been notified in writing by us that a declaration of non-residence or other claim or filing for exemption is required to be made);

(iv) to the extent that such Taxes would not have been so imposed if the Note had been presented for payment (where presentation is required) within 30 days after the date on which such payment or such Note became due and payable or the date on which payment thereof is duly provided for, whichever is later (except to the extent that the holder would have been entitled to Additional Amounts had the note been presented on the last day of such 30-day period); or

(v) any combination of items (i) through (iv) above.

The Company shall also make any applicable withholding or deduction and remit the full amount deducted or withheld to the relevant Taxing Jurisdiction in accordance with applicable law. The Company shall furnish to the Trustee, within 30 days after the date the payment of any Taxes deducted or withheld is due pursuant to applicable law, certified copies of tax receipts evidencing payment of such Taxes or, if such tax receipts are not reasonably available to the Company, such other documentation reasonably acceptable to the Trustee evidencing such payment by the Company. Copies of such receipts or other documentation shall be made available to the holders upon request.

The Company shall pay any present or future stamp, issue, registration, documentation, court, excise or property taxes or other similar taxes, charges and levies (including interest, penalties and Additional Amounts with respect thereto) imposed by any Taxing Jurisdiction in respect of or in connection with the execution, issue, delivery, redemption, retirement, enforcement or registration of the Notes, this Indenture or any other document or instrument in relation thereto and the Company shall agree to indemnify the holders and beneficial owners of the Notes for any taxes paid by such holders or beneficial owners.

The foregoing provisions shall survive any termination or discharge of this Indenture and the obligations under the Notes.

Whenever either in this Indenture there is mentioned, in any context, payment of principal (and premium, if any), redemption price, interest or any other amount payable under or with respect to any Note, such mention shall be deemed to include mention of the payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable by us in respect thereof.

The Company also will pay Additional Interest as provided for, and under the circumstances specified in, Section 5.10 and Section 7.01 of the Indenture.

2. Maturity. The Notes will mature on June 20, 2038.

Payment of the principal of and premium (including the Redemption Price, the Repurchase Price and the Fundamental Change Repurchase Price), if any, and accrued and unpaid interest and Additional Interest, if any, on this Note shall be made in such lawful money of the United States of America as at the time of payment shall be legal tender for the payment of public and private debts. Subject to the terms and conditions of the Indenture, payment in respect of the Redemption Price, the Repurchase Price, the Fundamental Change Repurchase Price and the principal amount on the Maturity Date, as the case may be, will be made to the holder who surrenders a Note to a Paying Agent to collect such payments in respect of the Note. If a payment date falls on a date that is not a Business Day, payment shall be postponed until the next succeeding Business Day, and no interest or other amount shall be paid as a result of any such postponement.

4. Paying Agent, Registrar, Conversion Agent. Initially, Deutsche Bank Trust Company Americas (the “Trustee”) will act as Paying Agent, Note Registrar and Conversion Agent. The Company may change any Paying Agent, Note Registrar or Conversion Agent without notice to the holders.

5. Indenture. The Company issued the Notes under an Indenture dated as of June 25, 2008 (the “Indenture”) between the Company and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code §§ 77aaa-77bbbb) (the “Trust Indenture Act”) as amended and in effect from time to time. The Notes are subject to all such terms, and holders are referred to the Indenture and the TIA for a statement of such terms. In the case of any conflict between the provisions of this Note and the Indenture, the provisions of the Indenture shall control. The Notes are general unsecured senior obligations of the Company limited to $150,000,000 aggregate principal amount ($210,000,000 if the Initial Purchasers have elected to exercise their option in full as set forth in the Purchase Agreement), except as otherwise provided in the Indenture (except for Notes issued in substitution for destroyed, mutilated, lost or stolen Notes).

Instead, the Company shall pay such interest and Additional Interest, if any, on the Interest Payment Date to the holder of record on the corresponding Interest Record Date. Notwithstanding the foregoing, no Notes may be redeemed by the Company if the principal amount of the Notes has been accelerated and such acceleration has not been rescinded on or prior to the Redemption Date (except in the case of an acceleration resulting from a default by the Company in the payment of the Redemption Price with respect to such Notes).

Subject to the terms and conditions of the Indenture, if there shall occur a Fundamental Change at any time prior to the Maturity Date, then each Noteholder shall have the right, at such holder’s option, to require the Company to repurchase for cash all of such holder’s Notes, or any portion thereof that is an integral multiple of $1,000 principal amount, on the date (the “Fundamental Change Repurchase Date”) specified by the Company that is not less than twenty Business Days and not more than forty-five Business Days after the date of the Fundamental Change Company Notice at a repurchase price equal to 100% of the principal amount thereof, together with accrued and unpaid interest, including accrued and unpaid Additional Interest, if any, thereon to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”), unless the Fundamental Change Repurchase Date is after an Interest Record Date and on or prior to the related Interest Payment Date, in which case interest accrued to the Interest Payment Date will be paid to holders of the Notes as of such Interest Record Date and the Fundamental Change Repurchase Price payable to the holder surrendering the Note for repurchase pursuant to this paragraph 9 shall be equal to 100% the principal amount of the Notes subject to repurchase.

10. Conversion. Subject to the provisions of the Indenture, the holder hereof has the right, at its option, at any time beginning on the date of the Indenture and ending prior to the close of business on the Business Day immediately preceding the Maturity Date, to convert any Notes or portion thereof that is $1,000 or an integral multiple thereof at the applicable Conversion Rate specified in the Indenture. Upon conversion of a Note, the Company will satisfy its conversion obligation by paying or delivering, as the case may be, cash, Common Shares or a combination of cash and Common Shares, in accordance with the terms of the Indenture.

The initial Conversion Rate is 95.6938 Common Shares per $1,000 principal amount of Notes (which results in an effective initial Conversion Price of approximately $10.45 per share) subject to adjustment in the event of certain circumstances as specified in the Indenture, including upon the occurrence of a Make-Whole Fundamental Change. The Company will deliver cash in lieu of any fractional share.

A Note in respect of which a holder had delivered a Fundamental Change Purchase Notice or a Repurchase Notice exercising the option of such holder to require the Company to purchase such Note may be converted only if the Fundamental Change Purchase Notice or Repurchase Notice, as the case may be, is withdrawn in accordance with the terms of the Indenture.

11. Denominations, Transfer, Exchange. The Notes are in registered form, without coupons, in denominations of $1,000 principal amount and integral multiples of $1,000 principal amount.

All Notes presented or surrendered for registration of transfer or for exchange, redemption, repurchase or conversion shall (if so required by the Company, the Trustee, the Note Registrar or any co-registrar) be duly endorsed or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company and duly executed, by the Noteholder thereof or its attorney-in-fact duly authorized in writing. No service charge shall be made for any such registration of transfer or

A-5

exchange, but the Company and the Trustee may require payment of a sum sufficient to cover any tax or similar governmental charge that may be imposed in connection with certain transfers or exchanges. None of the Company, the Trustee, the Note Registrar or any co-registrar shall be required to exchange or register a transfer of (i) any Notes surrendered for conversion or, if a portion of any Note is surrendered for conversion, such portion thereof surrendered for conversion, (ii) any Note selected for redemption or, if a portion of any Note is selected for redemption, such portion thereof selected for redemption or (ii) any Notes, or a portion of any Note, surrendered for repurchase (and not withdrawn) in accordance with Article 15 of the Indenture.

12. Persons Deemed Owners. The registered holder of a Note may be treated as the owner of such Note for all purposes.

14. Amendments, Supplements and Waivers. Subject to certain exceptions, the Indenture or the Notes may be amended or supplemented with the consent of the holders of at least a majority in aggregate principal amount of the outstanding Notes, and certain existing Defaults or Events of Default may be waived with the consent of the holders of a majority in aggregate principal amount of the Notes then outstanding. In accordance with the terms of the Indenture, the Company, with the consent of the Trustee, may amend or supplement this Indenture or the Notes without notice to or the consent of any Noteholder, including, but not limited to, to cure any ambiguity, defect, omission or inconsistency in the Indenture or conform the terms of the Indenture to the description thereof in the Offering Memorandum and to make any other change that does not materially and adversely affect the rights of any holder.

15. Defaults and Remedies. In case one or more Events of Default shall have occurred and be continuing (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body), then, and in each and every such case (other than as a result of certain events of bankruptcy, insolvency or reorganization specified in the Indenture), unless the principal of all of the Notes shall have already become due and payable, either the Trustee or the holders of at least 25% in aggregate principal amount of the Notes then outstanding may declare 100% of the principal of and premium, if any, and accrued and unpaid interest and accrued and unpaid Additional Interest, if any, on all the Notes to be due and payable immediately, and upon any such declaration the same shall become and shall automatically be immediately due and payable, all as and to the extent, and subject to the exceptions, provided in the Indenture. If an Event of Default as a result of certain events of bankruptcy, insolvency or reorganization specified in the Indenture occurs and is continuing, the principal of all the Notes and accrued and unpaid interest and accrued and unpaid Additional Interest, if any, shall be immediately due and payable without any declaration or other act on the part of the Trustee or any holder, all as and to the extent provided in the Indenture.

Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The holders of a majority in aggregate principal amount of the Notes then outstanding may 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 it. However, the Trustee may refuse to follow any direction that conflicts with any rule of law or the Indenture, is unduly prejudicial to the rights of other holders or would involve the Trustee in personal liability and the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. The Trustee may withhold notice of any continuing default (except a default in payment of any amounts due with respect to any Note), if it in good faith determines that, withholding the notice is in the best interests of holders. The Company must deliver to the Trustee an annual compliance certificate.

16. No Recourse Against Others. No past, present or future director, officer, employee or shareholder, as such, of the Company shall have any liability for any obligations of the Company under the Notes or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each holder, by accepting a Note, waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Notes.

17. Authentication. This Note shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent in accordance with the Indenture.

18. Governing Law. THE INTERNAL LAWS OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS NOTE, INCLUDING WITHOUT LIMITATION, SECTIONS 5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW AND NEW YORK CIVIL PRACTICE LAWS AND RULES 327(B).
