THE SECURITIES

Section 2.1 Initial Security Form and Dating

The Securities and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A to this Indenture which is hereby incorporated in, and expressly made a part of, this Indenture. The Series A Securities shall be issued in registered, global form to holders of Predecessor Securities that qualify as QIBs and exchange such Predecessor Securities for Series A Securities in compliance with the applicable Depository procedures. If a holder of Predecessor Securities does not qualify as a QIB or comply with such Depository procedures when exchanging such Predecessor Securities for Series A Securities, the Series A Securities issued to such holder shall be in the form of a Definitive Security. The Securities may have notations, legends or endorsements required by law, stock exchange rule, agreements to which the Company is subject, if any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Company). Each Security shall be dated the date of its authentication. Additional provisions that relate to the Securities are set forth in the Appendix attached hereto (the “Appendix”) which is hereby incorporated in, and expressly made part of, this Indenture. The terms of the Securities set forth in the Appendix and Exhibit A are part of the terms of this Indenture.

Section 2.2 Execution and Authentication

Two Officers shall sign the Securities for the Company by manual or facsimile signature.

If an Officer whose signature is on a Security no longer holds that office at the time the Trustee authenticates the Security, the Security shall be valid nevertheless.

A Security shall not be valid until an authorized signatory of the Trustee manually signs the certificate of authentication on the Security. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture.

On the Issue Date, the Trustee shall authenticate and deliver the Series A Securities and, at any time and from time to time thereafter, the Trustee shall authenticate and deliver Securities for original issue in an aggregate principal amount specified in such order, in each case upon a written order of the Company signed by at least one Officer. Such order shall specify the amount of the Securities to be authenticated and the date on which the original issue of Securities is to be authenticated.

The Trustee may appoint an authenticating agent reasonably acceptable to the Company to authenticate the Securities. Unless limited by the terms of such appointment, an authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as any Registrar, Paying Agent or agent for service of notices and demands.

9

Section 2.3 Definitive Custodian, Registrar and Paying Agent

The Company may maintain an office or agency where Definitive Securities may be held on behalf of the Securityholders (the “Definitive Custodian”), and shall maintain an office or agency where Securities may be presented for registration of transfer or for exchange (the “Registrar”) and an office or agency where Securities may be presented for payment (the “Paying Agent”). The Registrar shall keep a register of the Securities and of their transfer and exchange. The Company may have one or more co-registrars and one or more additional paying agents. The term “Paying Agent” includes any additional paying agent.

The Company shall enter into an appropriate agency agreement with any Definitive Custodian, Registrar, Paying Agent or co-registrar not a party to this Indenture, which shall incorporate the terms of the Trust Indenture Act. The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of the name and address of any such agent. If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.7. The Company may act as Definitive Custodian, Paying Agent, Registrar, co-registrar or transfer agent.

The Company initially appoints the Trustee as Registrar and Paying Agent in connection with the Securities. The Company initially will act as Definitive Custodian in connection with any Definitive Securities issued unless a Securityholder declines such services or elects at any time to request that such Holder’s Definitive Securities be delivered to such Holder. The Company may terminate its services as Definitive Custodian with respect to any or all Securityholders at any time, with or without cause, and will return such Holder’s Securities to the Holder promptly following such termination.

Section 2.4 Paying Agent To Hold Money in Trust

Prior to each due date of the principal and interest on any Security, the Company shall deposit with the Paying Agent a sum sufficient to pay such principal and interest when so becoming due. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Securityholders or the Trustee all money held by the Paying Agent for the payment of principal of or interest on the Securities and shall notify the Trustee of any default by the Company in making any such payment. If the Company or a Subsidiary acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon complying with this Section, the Paying Agent shall have no further liability for the money delivered to the Trustee.

Section 2.5 Securityholder Lists

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Securityholders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee, in writing at least five Business Days before each Interest Payment Date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Securityholders.

10

Section 2.6 Transfer and Exchange

The Securities shall be issued in (a) registered, global form for Holders of such Securities who comply with the applicable Depository procedures for obtaining an interest in a registered, global form Security and (b) definitive form for all other Holders, and in each case such Securities shall be transferable only upon the surrender of a Security for registration of transfer. When a Security is presented to the Registrar or a co-registrar with a request to register a transfer, the Registrar shall register the transfer as requested if the requirements of this Indenture (including Section 2.3 of the Appendix) are met. When Securities are presented to the Registrar or a co-registrar with a request to exchange them for (x) an equal principal amount of Securities of other denominations or (y) an equal principal amount of Global Securities, if such Securities presented were Definitive Securities, the Registrar shall make the exchange as requested if the same requirements are met.

Section 2.7 Replacement Securities

If a mutilated Security is surrendered to the Registrar or if the Holder of a Security claims that the Security has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Security. If required by the Trustee or the Company, such Holder shall furnish an indemnity bond sufficient in the judgment of the Company and the Trustee to protect the Company, the Trustee, the Paying Agent, the Registrar and any co-registrar from any loss which any of them may suffer if a Security is replaced. The Company and the Trustee may charge the Holder for their expenses in replacing a Security.

Every replacement Security is an additional obligation of the Company.

Section 2.8 Outstanding Securities

Securities outstanding at any time are all Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section as not outstanding. A Security does not cease to be outstanding because the Company or an affiliate of the Company holds the Security, but, in certain circumstances, Section 10.6 provides that certain Securities shall be disregarded.

If a Security is replaced pursuant to Section 2.7, it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Security is held by a protected purchaser (as defined in Section 8-303 of the Uniform Commercial Code).

If the Paying Agent (other than the Company) holds on a redemption date or maturity date money sufficient to pay all principal and interest payable on that date with respect to the Securities (or portions thereof) to be redeemed or maturing, or on a Conversion Date a combination of Common Shares and money sufficient to satisfy all conversion obligations pursuant to Article V hereof on such Conversion Date with respect to the Securities (or portions thereof) to be converted, as the case may be, then on and after that date such Securities (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

11

Section 2.9 Temporary Securities

Until definitive Securities are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Securities and deliver them in exchange for temporary Securities.

Section 2.10 Cancellation

The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel and destroy (subject to the record retention requirements of the Exchange Act) all Securities surrendered for registration of transfer, exchange, payment or cancellation and deliver a certificate of such destruction to the Company unless the Company directs the Trustee to deliver canceled Securities to the Company. The Company may not issue new Securities to replace Securities it has redeemed, converted, paid or delivered to the Trustee for cancellation.

Section 2.11 Defaulted Interest

If the Company defaults in a payment of interest on the Securities, the Company shall pay defaulted interest (plus interest on such defaulted interest to the extent lawful) in any lawful manner. The Company may pay the defaulted interest to the Persons who are Securityholders on a subsequent special record date. The Company shall fix or cause to be fixed any such special record date and payment date; provided that no such special record date shall be less than 10 days prior to the related payment date for such defaulted interest. The Company shall promptly notify the Trustee of any such special record date. At least 15 days before any such special record date, the Company shall mail or cause to be mailed, first-class postage prepaid, or otherwise deliver in accordance with the applicable procedures of the Depository, to each Securityholder, with a copy to the Trustee, a notice at its address as it appears in the Registrar’s books that states the special record date, the related payment date and the amount of such interest to be paid.

Section 2.12 CUSIP Numbers, ISINs, etc.

The Company in issuing the Securities may use “CUSIP” numbers, ISINs and “Common Code” numbers (in each case if then generally in use) and, if so, the Trustee shall use “CUSIP” numbers, ISINs and “Common Code” numbers in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company shall advise the Trustee in writing of any change in any “CUSIP” numbers, ISINs or “Common Code” numbers applicable to the Securities.

12

Section 2.13 Issuable in Series

The aggregate principal amount of Securities that may be authenticated and delivered under this Indenture is unlimited.

The Securities may be issued in one or more series (each Security issued after the Issue Date, an “Additional Security”). Any series of Additional Securities shall be established pursuant to a Board Resolution and a supplemental indenture to this Indenture. All series of Securities shall be substantially identical except for (i) the title of the Securities of the series (which shall distinguish the Securities of the series from Securities of any other series), (ii) the date of original issuance of the Securities, (iii) the Conversion Price of the Securities, and (iv) such other terms as may be specified in the supplemental indenture relating to the creation of such series (which terms shall not be inconsistent with the provisions of this Indenture, except as permitted by Article IX). Additional Securities shall have the same redemption provisions, interest rate and maturity date as the Series A Securities. Additional Securities may be issued with accrued interest. All Securities issued under this Indenture shall vote as a single class with respect to all directions, waivers and consents under this Indenture and the Securities, including for purposes of Sections 6.2, 6.4, 6.5, 6.6 and 9.2.

All Securities of any one series shall be substantially identical except as to denomination. All Securities of any one series need not be issued at the same time and after issuance of Securities of such series, such series may be reopened for issuances of additional Securities of that series.

Upon surrender to the Paying Agent, such Securities shall be paid at the redemption price stated in the notice, plus accrued interest to the redemption date (subject to the right of Holders of record on the relevant Regular Record Date to receive interest due on the related Interest Payment Date), and such Securities shall be canceled by the Trustee.

No failure of the Company to give the foregoing notices and no defect therein shall limit the repurchase rights of the Holders or affect the validity of the proceedings for the repurchase of the Securities pursuant to this Section 4.3.

(c) Repurchases of Securities under this Section 4.3 shall be made, at the option of the Holders thereof, upon:

To the extent that the provisions of any securities laws or regulations conflict with provisions of this Section, the Company shall comply with the applicable securities laws and regulations and shall be deemed not to have breached its obligations under this Section by virtue of its compliance with such securities laws or regulations.

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

Sale 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.

No failure of the Company to give the foregoing notices and no defect therein shall limit the repurchase rights of the Holders or affect the validity of the proceedings for the repurchase of the Securities pursuant to this Section 4.5.

(b) The price (per $1,000 principal amount of Securities) that the Company shall be required to pay shall be equal to the price which the Company would be required to pay in an optional redemption on the Asset Sale Purchase Date under paragraph 5 of the Securities, plus accrued and unpaid interest to, but excluding, the Asset Sale Purchase Date. If an Asset Sale Purchase Date occurs prior to July 1, 2015, the Company shall be required to pay a price equal to the price that the Company would be required to pay upon an optional redemption on July 1, 2015, plus accrued and unpaid interest to, but excluding, the Asset Sale Purchase Date.

ARTICLE V

CONVERSION

Section 5.1 Right of Conversion

Each Securityholder shall have the right, at any time after July 1, 2015 and from time to time, at such Securityholder’s option, to convert, pursuant to and subject to the terms and provisions of the Securities and this Article V, any or all of the outstanding principal of such Securityholder’s Securities into fully paid and nonassessable Common Shares at the Conversion Price (such Common Shares, the “Conversion Shares”). Prior to or contemporaneously with the conversion of any of the principal of the Securities, all accrued but unpaid interest on the principal amount being converted must be paid in cash. The Securities may not be converted into Conversion Shares on the Maturity Date or the date fixed for any redemption pursuant to Article III of this Indenture and paragraph 5 of the Securities.

Section 5.2 Mechanics of Exercise

(a) Before any Securityholder shall be entitled to convert a Security as set forth above, such Securityholder shall (i) in the case of a Global Security, comply with the applicable procedures of the Depository in effect at that time, including the delivery of any applicable instruction form for conversion pursuant to the Depository’s conversion program and (ii) in the case of a Definitive Security (1) complete, manually sign and deliver an irrevocable notice to the Trustee as set forth in the Form of Notice of Conversion attached to the Form of Security (or a facsimile thereof) (a “Notice of Conversion”) at the corporate trust office of the Trustee and state in writing therein the principal amount of Securities to be converted and the name or names (with addresses) in which such Securityholder

22

wishes the certificate or certificates for any Conversion Shares to be delivered, (2) surrender such Securities, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the corporate trust office of the Trustee and (3) if required, furnish appropriate endorsements and transfer documents.

(b) Following surrender for conversion, the converted Securities shall be cancelled and, if appropriate, a new Security reflecting the amount of the unconverted principal shall be issued to such Securityholder.

(c) The Trustee shall notify the Company of any conversion pursuant to this Article V promptly following the Conversion Date of such conversion.

(d) No Securityholder may surrender Securities for conversion if such Securityholder has also delivered a Fundamental Change Purchase Notice to the Company in respect of such Securities and not validly withdrawn such Fundamental Change Purchase Notice in accordance with Section 4.3(e).

(e) If more than one Security shall be surrendered for conversion at one time by the same Securityholder, the amount of Conversion Shares with respect to such Securities shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof to the extent permitted thereby) so surrendered.

(f) Upon the conversion of an interest in a Global Security, the Trustee shall cause such Global Security (or related book entries) to be adjusted to reflect the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversion of Securities effected through any agent other than the Trustee.

Section 5.3 Issuance of Shares; Time of Conversion

A Security shall be deemed to have been converted immediately prior to the close of business on the date (the “Conversion Date”) that the Securityholder has complied with the requirements set forth in Section 5.2(a) above.

As promptly as practicable after the Conversion Date, the Company shall deliver or cause to be delivered to such Securityholder a certificate for the Conversion Shares issuable in connection with such conversion. To the extent permitted by law, the rights of such Securityholder shall, to the extent of principal converted, cease with respect to such principal as of the Conversion Date, and the Person entitled to receive the Conversion Share certificate deliverable upon such conversion shall be treated for all purposes as having become the record holder of such Conversion Shares at such time.

23

Section 5.4 Adjustment of Conversion Price

The Conversion Price, and consequently the number of Conversion Shares into which the Securities are convertible, shall be subject to adjustment as follows:

(a) If at any time the Company shall:

(i) take a record of the holders of its Common Shares for the purpose of entitling them to receive a dividend payable in, or other distribution of, Common Shares;

(ii) subdivide its outstanding Common Shares into a larger number of Common Shares; or

(iii) combine its outstanding Common Shares into a smaller number of Common Shares;

then in each such case the Conversion Price in effect immediately prior thereto shall be adjusted so that the Securityholders of the Securities upon conversion shall be entitled to receive the number of Common Shares that the Securityholders would have owned or have been entitled to receive after the happening of any of the events described above had the Securities been converted immediately prior to the happening of such event.

If the Company shall take a record of the holders of its Common Shares for the purpose of entitling them to receive a dividend or distribution and shall, thereafter and before the distribution to shareholders thereof, legally abandon its plan to pay or deliver such dividend or distribution, then thereafter no adjustment shall be required by reason of the taking of such record and any such adjustment previously made in respect thereof shall be rescinded and annulled.

(b) In case the Company shall reorganize its capital, reclassify its capital stock, consolidate or merge with and into another corporation (where the Company is not the surviving corporation or where there is a change in or distribution with respect to the Common Shares of the Company), or sell, transfer or otherwise dispose of all or substantially all its property, assets or business to another corporation and, pursuant to the terms of such reorganization, reclassification, merger, consolidation or disposition of assets, shares of common stock of the successor or acquiring corporation, or any cash, shares of stock or other securities or property of any nature whatsoever (including warrants or other subscription or purchase rights) in addition to or in lieu of common stock of the successor or acquiring corporation (“Other Property”), are to be received by or distributed to the holders of Common Shares of the Company, then the Company shall, as a condition precedent to such transaction, cause effective provisions to be made so that the Securityholders shall have the right thereafter to receive, upon conversion of the Securities, solely the number of shares of common stock of the successor or acquiring corporation or of the Company, if it is the surviving corporation, and Other Property receivable upon or as a result of such reorganization, reclassification, merger, consolidation or disposition of assets, by a holder of the number of Common Shares for which the Securities would have been convertible immediately prior to such event. In case of any such reorganization, reclassification, merger, consolidation or disposition of assets, such provisions shall include the express assumption by the successor or acquiring corporation (if

24

other than the Company) of the due and punctual observance and performance of each and every covenant and condition of this Indenture and the Securities to be performed and observed by the Company and all the obligations and liabilities hereunder and thereunder, subject to such modifications as may be deemed appropriate (as determined by Board Resolution of the Company) in order to provide for adjustments of Common Shares for which the Securities are convertible which shall be as nearly equivalent as practicable to the adjustments provided for in this Article V. For purposes of this Section, “common stock of the successor or acquiring corporation” shall include stock of such corporation of any class which is not preferred as to dividends or assets over any other class of stock of such corporation and which is not subject to redemption and shall also include any evidences of indebtedness, shares of stock or other securities which are convertible into or exchangeable for any such stock, either immediately or upon the arrival of a specified date or the happening of a specified event and any warrants or other rights to subscribe for or purchase any such stock. The foregoing provisions of this Section shall similarly apply to successive reorganizations, reclassifications, mergers, consolidations or dispositions of assets.

Section 5.5 No Fractional Shares

Instead of any fractional Conversion Share that would otherwise be issuable upon conversion of any Securities, the Company may pay a cash adjustment in respect of such fraction in an amount equal to the same fraction of the Conversion Price.

Section 5.6 Notice of Adjustments

Whenever the Conversion Price shall be adjusted pursuant to Section 5.4, the Company shall forthwith prepare a certificate to be executed by the chief financial officer of the Company setting forth, in reasonable detail, the event requiring the adjustment and the method by which such adjustment was calculated (including a description of the basis on which the Board of Directors determined the fair value of any Other Property referred to in Section 5.4(b)), specifying the Conversion Price and (if applicable) describing the number and kind of any other shares of stock or Other Property into which the Securities may be converted, and any change in the purchase price or prices thereof, after giving effect to such adjustment or change. The Company shall promptly cause a signed copy of such certificate to be delivered to the Trustee in accordance with Section 10.2. The Company shall keep at its chief executive office copies of all such certificates and cause the same to be available for inspection at said office during normal business hours by any Securityholders or any prospective purchaser of the Securities designated by the Securityholder.

Section 5.7 No Shareholder Rights

Prior to the issuance of Conversion Shares, the Securityholders shall not be entitled to any rights of a shareholder with respect to the Common Shares, including the right to vote such Common Shares, receive dividends or other distributions thereon, exercise preemptive rights or be notified of shareholder meetings, and the Securityholders shall not be entitled to any notice or other communication concerning the business or affairs of the Company except as contractually agreed to by the Company.

25

Section 5.8 Shares to be Reserved

The Company covenants that it will at all times reserve and keep available out of its authorized but unissued Common Shares, free from preemptive rights, solely for the purpose of issue upon conversion of the Securities as herein provided, such number of Common Shares as shall then be issuable upon the conversion of all principal of the Securities. The Company covenants that all Conversion Shares which shall be so issuable shall, when issued, be duly and validly issued and fully paid and nonassessable.

Section 5.9 No Registration of Shares

The Conversion Shares have not been registered with the SEC or any other governmental authority. The Company shall cause any Conversion Shares to bear a restrictive legend describing limitations of the transferability of such Conversion Shares until such time as the restrictive legend may be removed.

Section 5.10 Taxes and Charges

The issuance of certificates for Conversion Shares upon the conversion of any Securities shall be made without charge to the converting Securityholder or for any tax in respect of the issuance of such certificates or the securities represented thereby, and such certificates shall be issued in the name of, or in such names as may be directed by, such Securityholder; provided, however, that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of any such certificate in a name other than that of the converting Securityholder, and the Company shall not be required to issue or deliver such certificates unless or until the Person or Persons requesting the issuance thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid.

Section 5.11 Responsibility of Trustee

The Trustee and any other conversion agent shall not at any time be under any duty or responsibility to any Securityholders to determine the Conversion Price or whether any facts exist that may require any adjustment (including any decrease) of the Conversion Price, 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 Security; 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 Security for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article V. Without limiting the generality of the foregoing, neither the Trustee nor any other

26

conversion agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 5.4 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Securityholders upon the conversion of their Securities after any event referred to in such Section or to any adjustment to be made with respect thereto, but may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers’ Certificate and Opinion of Counsel (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto.

ARTICLE VI

DEFAULTS AND REMEDIES

Section 6.1 Events of Default

An “Event of Default” occurs if:

(a) the Company defaults in the payment of principal of or interest on any Security when the same becomes due and payable (including any failure to repurchase Securities pursuant to Section 4.3 or 4.5 at the time required thereunder) and such default continues for 15 days;

(b) the Company fails to observe or perform any other covenant or agreement contained in this Indenture and such default continues for 30 days after the Company has received written notice thereof;

(c) the Company fails to make any payment of principal of or interest on any indebtedness for money borrowed when due after giving effect to any applicable grace periods (whether due by acceleration or otherwise) and the aggregate amount of all such past-due indebtedness (including indebtedness accelerated pursuant to the terms thereof) shall be equal to or greater than $10.0 million; or

(d) the Company (i) commences a voluntary case concerning itself under any Bankruptcy Law now or hereafter in effect, or any successor thereof; (ii) is the object of an involuntary case under any Bankruptcy Law; or (iii) commences any Distribution Event or is the object of an involuntary Distribution Event.

A Default under subsection (b) shall not constitute an Event of Default until the Trustee or the holders of 25% in principal amount of the outstanding Securities notify the Company of the Default and the Company does not cure such Default within the time specified after receipt of such notice. Such notice must specify the Default, demand that it be remedied, and state that such notice is a “Notice of Default.”

Section 6.2 Acceleration

(a) If an Event of Default specified in Sections 6.1(a), 6.1(b), or 6.1(c) shall occur and be continuing, the Trustee by notice to the Company, or the Holders of at least 25% in principal amount of the outstanding Securities by notice to the Company and the Trustee, may declare the principal of and accrued but unpaid interest on all the Securities to be due and payable. Upon such a declaration, such principal and interest shall be due and payable immediately.

27

(b) If an Event of Default specified in Section 6.1(d) shall occur and be continuing, the principal of and interest on all the Securities shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Securityholders.

(c) The Holders of a majority in principal amount of the Securities by notice to the Trustee may rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of principal or interest that has become due solely because of acceleration. No such rescission shall affect any subsequent Default or impair any right consequent thereto.

(d) In the event of a declaration of acceleration of the Securities solely because an Event of Default described in Section 6.1(c) has occurred and is continuing, the declaration of acceleration of the Securities shall be automatically rescinded and annulled if the payment default triggering such Event of Default pursuant to Section 6.1(c) shall be remedied or cured by the Company or waived by the holders of the relevant indebtedness within 20 Business Days after the declaration of acceleration with respect thereto and if the rescission and annulment of the acceleration of the Securities would not conflict with any judgment or decree of a court of competent jurisdiction obtained by the Trustee for the payment of amounts due on the Securities.

Section 6.3 Other Remedies

(a) If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture.

(b) The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Securityholder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative.

Section 6.4 Waiver of Past Defaults

The Holders of a majority in principal amount of the Securities by notice to the Trustee may waive an existing Default and its consequences except:

(a) a Default in the payment of the principal of or interest on a Security;

28

(b) a Default arising from the failure to redeem or purchase any Security when required pursuant to this Indenture; or

(c) a Default in respect of a provision that under Section 9.2 cannot be amended without the consent of each Securityholder affected.

When a Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or impair any consequent right.

Section 6.5 Control by Majority

The Holders of a majority in principal amount of the Securities may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or, subject to Section 7.1, that the Trustee determines is unduly prejudicial to the rights of other Securityholders or may involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any action under this Indenture, the Trustee shall be entitled to indemnification or security satisfactory to it against any losses, liability and expenses in taking such action.

Section 6.6 Limitation on Suits

Except to enforce the right to receive payment of principal, premium (if any) or interest when due, no Securityholder may pursue any remedy with respect to this Indenture or the Securities unless:

(a) such Holder has previously given the Trustee notice that an Event of Default is continuing;

(b) Holders of at least 25% in principal amount of the outstanding Securities have requested the Trustee to pursue the remedy;

(c) such Holders have offered the Trustee reasonable security or indemnity against any loss, liability or expense;

(d) the Trustee has not complied with such request within 60 days after the receipt thereof and the offer of security or indemnity; and

(e) Holders of a majority in principal amount of the outstanding Securities have not given the Trustee a direction inconsistent with such request within such 60-day period.

Section 6.7 Rights of Holders to Receive Payment

Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of and interest on the Securities held by such Holder, on or after the respective due dates expressed in the Securities, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

29

Section 6.8 Collection Suit by Trustee

If an Event of Default specified in Section 6.1(a) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount then due and owing (together with interest on any unpaid interest to the extent lawful) and the amounts provided for in Section 7.7.

Section 6.9 Trustee May File Proofs of Claim

The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and the Securityholders allowed in any judicial proceedings relative to the Company, its creditors or its property and to collect, receive and distribute any money or other property payable or deliverable on any such claims, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.7. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.10 Priorities

If the Trustee collects any money or property pursuant to this Article VI, it shall pay out the money or property in the following order:

FIRST: to the Trustee for amounts due under Section 7.7;

SECOND: to Securityholders for amounts due and unpaid on the Securities for principal and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal and interest, respectively; and

THIRD: to the Company.

The Trustee may fix a record date and payment date for any payment to Securityholders pursuant to this Section.

Section 6.11 Undertaking for Costs

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, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and

30

expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.7 or a suit by Holders of more than 10% in aggregate principal amount of the outstanding Securities.

ARTICLE VII

TRUSTEE

Section 7.1 Duties of Trustee

(a) If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise as a prudent Person would exercise or use under the circumstances in the conduct of such Person’s own affairs.

(g) The Trustee shall have no duty to inquire as to the performance of the Company’s covenants in Article IV. In addition, the Trustee shall not be deemed to have knowledge of any Default or Event of Default except: (i) any Event of Default occurring pursuant to Section 6.1(a); or (ii) any Default or Event of Default of which a Responsible Officer shall have received written notification and such notification references the Securities and this Indenture.

32

(i) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other person employed by it to act hereunder.

Section 7.3 Individual Rights of Trustee

The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or its affiliates with the same rights it would have if it were not Trustee. Any Paying Agent, Registrar, co-registrar or co-paying agent may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11.

33

Section 7.4 Trustee’s Disclaimer

The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Securities, it shall not be accountable for the Company’s use of the proceeds from the Securities, and it shall not be responsible for any statement of the Company in this Indenture or in any document issued in connection with the sale of the Securities or in the Securities other than the Trustee’s certificate of authentication.

Section 7.5 Notice of Defaults

If a Default occurs, is continuing and is known to the Trustee, the Trustee shall send to each Securityholder notice of the Default within 90 days after it becomes known to it. Except in the case of a Default in the payment of principal of or interest on any Security (including payments pursuant to the mandatory purchase provisions of such Security), the Trustee may withhold the notice if and so long as a committee of its Trust Officers in good faith determines that withholding the notice is not opposed to the interests of the Securityholders.

Section 7.6 Reports by Trustee to Holders

As promptly as practicable after each May 15 beginning with the May 15 following the date of this Indenture, and in any event prior to July 15 in each year, the Trustee shall mail to each Securityholder a brief report dated as of May 15 that complies with Trust Indenture Act § 313(a). The Trustee also shall comply with Trust Indenture Act § 313(b).

A copy of each report at the time of its mailing to Securityholders shall be filed with the SEC and each stock exchange (if any) on which the Securities are listed. The Company agrees to notify promptly the Trustee whenever the Securities become listed on any stock exchange and of any delisting thereof.

Section 7.7 Compensation and Indemnity

The Company shall pay to the Trustee from time to time such compensation for its services as the parties shall agree in writing from time to time. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall promptly reimburse the Trustee upon request for all reasonable out-of-pocket disbursements, advances and expenses incurred or made by it, including costs of collection, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts.

The Company shall indemnify the Trustee and its officers, directors, employees, agents and attorneys against any and all loss, liability or expense (including attorneys’ fees and expenses) incurred by it in connection with the administration of this trust and the performance of its duties hereunder. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee may have separate counsel and the Company shall pay the fees and expenses of such counsel. The Company need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee’s own willful misconduct, negligence or bad faith.

34

To secure the Company’s payment obligations in this Section, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee other than money or property held in trust to pay principal of and interest on particular Securities.

The Company’s payment obligations pursuant to this Section shall survive the satisfaction and discharge of this Indenture. When the Trustee incurs expenses or renders services after the occurrence of a Default specified in Section 6.1(d) with respect to the Company, the expenses and the compensation for such services are intended to constitute expenses of administration under the Bankruptcy Law.

Section 7.8 Replacement of Trustee

(a) The Trustee may resign at any time by so notifying the Company. The Holders of a majority in principal amount of the outstanding Securities may remove the Trustee by so notifying the Trustee and may appoint a successor Trustee.

(ii) the Trustee is adjudged bankrupt or insolvent;

(iii) a receiver or other public officer takes charge of the Trustee or its property; or

(iv) the Trustee otherwise becomes incapable of acting.

(c) If the Trustee resigns, is removed by the Company or by the Holders of a majority in principal amount of the Securities and such Holders do not reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Company shall promptly appoint a successor Trustee.

(d) A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall send a notice of its succession to Securityholders. Upon payment of all sums owing to it hereunder, the retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.7.

(e) If a successor Xxxxxxx does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee or the Holders of 10% in principal amount of the outstanding Securities may petition any court of competent jurisdiction for the appointment of a successor Trustee.

35

(f) If the Trustee fails to comply with Section 7.10, any Securityholder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

(g) Notwithstanding the replacement of the Trustee pursuant to this Section, the Company’s obligations under Section 7.7 shall continue for the benefit of the retiring Trustee.

Section 7.9 Successor Trustee by Xxxxxx

(a) If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee.

(b) In case at the time such successor or successors by merger, conversion or consolidation to the Trustee shall succeed to the trusts created by this Indenture any of the Securities shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee, and deliver such Securities so authenticated; and in case at that time any of the Securities shall not have been authenticated, any successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Securities or in this Indenture provided that the certificate of the Trustee shall have.

Section 7.10 Eligibility; Disqualification

The Trustee shall at all times satisfy the requirements of Trust Indenture Act § 310(a). The Trustee shall have a combined capital and surplus of at least $50.0 million as set forth in its most recent published annual report of condition. The Trustee shall comply with Trust Indenture Act § 310(b); provided, however, that there shall be excluded from the operation of Trust Indenture Act § 310(b)(1) any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Company are outstanding if the requirements for such exclusion set forth in Trust Indenture Act § 310(b)(1) are met. To the extent permitted by the Trust Indenture Act, the Trustee shall not be deemed to have a conflicting interest by virtue of being a trustee under this Indenture with respect to Securities of more than one series.

Section 7.11 Preferential Collection of Claims Against Company

Upon and so long as the Indenture is qualified under the Trust Indenture Act, the Trustee will be subject to Trust Indenture Act § 311(a), excluding any creditor relationship listed in Trust Indenture Act § 311(b). A Trustee who has resigned or been removed shall be subject to Trust Indenture Act § 311(a) to the extent indicated.

Section 8.1 Discharge of Liability on Securities; Defeasance

(a) When (i) the Company delivers to the Trustee all outstanding Securities (other than Securities replaced pursuant to Section 2.7) for cancellation or (ii) all outstanding Securities have become due and payable, whether at maturity, on a redemption date as a result of the sending of a notice of redemption pursuant to Article III hereof, or on a repurchase date pursuant to Section 4.3 or 4.5, or upon conversion of all Securities pursuant to Article V hereof, and, in the case of clause (ii), the Company irrevocably deposits with the Trustee funds sufficient to pay at maturity or upon redemption or repurchase all outstanding Securities, or, in order to satisfy the Company’s conversion obligations pursuant to Article V hereof, a combination of funds and Common Shares sufficient to pay all outstanding Securities and satisfy all outstanding conversion obligations pursuant to Article V hereof, including, in each case, interest thereon to maturity, such redemption date, repurchase date or such Conversion Date (other than Securities replaced pursuant to Section 2.7), and if in any case the Company pays all other sums payable hereunder by the Company, then this Indenture shall, subject to Section 8.1(c), be satisfied and discharged and shall cease to be of further effect.

(b) Subject to Sections 2.3, 2.6, 2.7, 8.1(c) and 8.2, the Company at any time may terminate (1) all its obligations under the Securities and this Indenture (“legal defeasance option”) or (2) its obligations under Sections 4.2, 4.3, 4.4, 4.5, 4.6, 4.7 and 4.8 and the operation of Sections Section 6.1(b), 6.1(c) and 6.1(d) (“covenant defeasance option”). The Company may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option.

If the Company exercises its legal defeasance option, payment of the Securities may not be accelerated because of an Event of Default with respect thereto. If the Company exercises its covenant defeasance option, payment of the Securities may not be accelerated because of an Event of Default specified in Sections 6.1(b), 6.1(c) and 6.1(d).

Upon satisfaction of the conditions set forth herein and upon request of the Company, the Trustee shall acknowledge in writing the discharge of those obligations that the Company terminates.

(c) Notwithstanding clauses (a) and (b) above, the Company’s obligations in Sections 2.3, 2.4, 2.5, 2.6, 2.7, 7.7 and 7.8 and in this Article VIII shall survive until the Securities have been paid in full. Thereafter, the Company’s obligations in Sections 7.7, 8.4 and 8.5 shall survive.

37

Section 8.2 Conditions to Defeasance

The Company may exercise its legal defeasance option or its covenant defeasance option only if:

(b) the Company delivers to the Trustee a certificate from a nationally recognized firm of independent accountants expressing their opinion that the payments of principal and interest when due and without reinvestment on the deposited U.S. Government Obligations plus any deposited money without investment will provide cash at such times and in such amounts as will be sufficient to pay principal and interest when due on all the Securities to maturity, redemption or conversion, as the case may be;

(c) 91 days pass after the deposit is made and during the 91-day period no Default specified in Section 6.1(d) occurs which is continuing at the end of the period;

Except as specified in Section 2.1 of the Indenture: Initial Securities initially sold pursuant to Rule 144A under the Securities Act (“Rule 144A”) shall be issued initially in the form of one or more permanent global Securities for each series in definitive, fully registered form (collectively, the “Rule 144A Global Security”); Initial Securities initially sold pursuant to Regulation S shall be issued initially in the form of one or more temporary global securities for each series in fully registered form (collectively, the “Temporary Regulation S Global Security”); and Initial Securities initially sold to IAIs that are not QIBs shall be issued, to the extent permissible under the applicable procedures of the Depository, initially in the form of one or more permanent global Securities in definitive, fully registered form (collectively, the “IAI Global Security”), in each case without interest coupons and with the global securities legend and the applicable restricted securities legend set forth in Exhibit A to the Indenture, which shall be deposited on behalf of the purchasers of the Initial Securities represented thereby with the Securities Custodian and registered in the name of the Depository or a nominee of the Depository, duly executed by the Company and authenticated by the Trustee as provided in this Indenture. During the Distribution Compliance Period, beneficial interests in the Temporary Regulation S Global Securities may be held only through the Euroclear System (“Euroclear”) and Clearstream Banking, S.A. (“Clearstream”) (as indirect participants in DTC), unless transferred to a person that takes delivery through a Rule 144A Global Security or IAI Global Security in accordance with the certification requirements described below. Within a reasonable time period after the expiration of the Distribution Compliance Period, the Temporary Regulation S Global

3

Securities will be exchanged for one or more permanent securities in registered, global form without interest coupons (collectively, the “Permanent Regulation S Global Security” and, together with the Regulation S Temporary Global Security, the “Regulation S Global Security”). Except as set forth in this Section 2.1(a), beneficial interests in the Global Security (as defined below) may not be exchanged for beneficial interests in the other Global Security at any time.

Prior to the expiration of the Distribution Compliance Period, beneficial interests in Regulation S Global Securities may be exchanged for interests in Rule 144A Global Securities if (1) such exchange occurs in connection with a transfer of Securities in compliance with Rule 144A and (2) the transferor of the beneficial interest in the Regulation S Global Security, first delivers to the Trustee a written certificate (substantially in the form of Exhibit 1) to the effect that the beneficial interest in the Regulation S Global Security, is being transferred to a Person (a) who the transferor reasonably believes to be a QIB, (b) purchasing for its own account or the account of a QIB in a transaction meeting the requirements of Rule 144A, and (c) in accordance with all applicable securities laws of the States of the United States and other jurisdictions.

Beneficial interests in Rule 144A Global Securities may be exchanged for an interest in IAI Global Securities if (1) such exchange occurs in connection with a transfer of the securities in compliance with an exemption under the Securities Act and (2) the transferor of the Rule 144A Global Security first delivers to the Trustee a written certificate (substantially in the form of Exhibit 1) to the effect that the beneficial interest in the Rule 144A Global Security is being transferred (a) to an “accredited investor” within the meaning of 501(a)(1),(2),(3) and (7) under the Securities Act that is an institutional accredited investor acquiring the securities for its own account or for the account of such an institutional accredited investor, for investment purposes and not with a view to or for offer or sale in connection with any distribution in violation of the Securities Act and (b) in accordance with all applicable securities laws of the States of the United States and other jurisdictions.

Beneficial interests in a Rule 144A Global Security or an IAI Global Security may be transferred to a Person who takes delivery in the form of an interest in a Regulation S Global Security, whether before or after the expiration of the Distribution Compliance Period, only if the transferor first delivers to the Trustee a written certificate (substantially in the form of Exhibit 1) to the effect that such transfer is being made in accordance with Regulation S or Rule 144 (if available) and that, if such transfer occurs prior to the expiration of the Distribution Compliance Period, the interest transferred will be held immediately thereafter through Euroclear or Clearstream.

The Rule 144A Global Security, the IAI Global Security, the Temporary Regulation S Global Security and the Permanent Regulation S Global Security are Global Securities.

7

(ii) written instructions directing the Trustee to make, or to direct the Securities Custodian to make, an adjustment on its books and records with respect to such Rule 144A Global Security (in the case of a transfer pursuant to clause (b)(i)(A)), IAI Global Security (in the case of a transfer pursuant to clause (b)(i)(B)) or Permanent Regulation S Global Security (in the case of a transfer pursuant to clause (b)(i)(C)) to reflect an increase in the aggregate principal amount of the Securities represented by the Rule 144A Global Security, IAI Global Security or Permanent Regulation S Global Security, as applicable, such instructions to contain information regarding the Depository account to be credited with such increase,

(ii) If the proposed transfer is a transfer of a beneficial interest in one Global Security to a beneficial interest in another Global Security, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the Global Security to which such interest is being transferred in an amount equal to the principal amount of the interest to be so transferred, and the Registrar shall reflect on its books and records the date and a corresponding decrease in the principal amount of the Global Security from which such interest is being transferred.

(iii) Notwithstanding any other provisions of this Appendix (other than the provisions set forth in Section 2.4), a Global Security may not be transferred as a whole except by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any such nominee to a successor Depository or a nominee of such successor Depository.

(iv) In the event that a Global Security is exchanged for Definitive Securities pursuant to Section 2.4 of this Appendix, prior to the consummation of a Registered Exchange Offer or the effectiveness of a Shelf Registration Statement with respect to such Securities, such Securities may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of this Section 2.3 (including the certification requirements set forth on the reverse of the Initial Securities intended to ensure that such transfers comply with Rule 144A, Regulation S or another applicable exemption under the Securities Act, as the case may be) and such other procedures as may from time to time be adopted by the Company.

THIS SECURITY (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND THIS SECURITY MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM.

THE HOLDER OF THIS SECURITY AGREES FOR THE BENEFIT OF THE COMPANY THAT (A) THIS SECURITY MAY BE OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (I) IN THE UNITED STATES TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (II) TO AN INSTITUTIONAL “ACCREDITED INVESTOR” (AS DEFINED IN RULE 501(A)(1),(2),(3) OR (7) UNDER THE SECURITIES ACT OF 1933), (III) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN ACCORDANCE WITH REGULATION S UNDER THE SECURITIES ACT, (IV) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER (IF AVAILABLE) OR (V) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, IN EACH OF CASES (I) THROUGH (V) IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES, AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER OF THIS SECURITY FROM IT OF THE RESALE RESTRICTIONS REFERRED TO IN (A) ABOVE.

Each Definitive Security shall also bear the following additional legend:

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

(ii) Upon any sale or transfer of a Transfer Restricted Security (including any Transfer Restricted Security represented by a Global Security) pursuant to Rule 144 under the Securities Act, the Registrar shall permit the transferee thereof to exchange such Transfer Restricted Security for a certificated Security that does not bear the legend set forth above and rescind any restriction on the transfer of such Transfer Restricted Security, if the transferor thereof certifies in writing to the Registrar that such sale or transfer was made in reliance on Rule 144 (such certification to be in the form set forth on the reverse of the Security).

(iii) After a transfer of any Initial Securities or Exchange Securities pursuant to and during the period of the effectiveness of a Shelf Registration Statement with respect to such Initial Securities or Exchange Securities, as the case may be, all requirements pertaining to legends (other than the Global Securities Legend, if applicable) on such Initial Security or such Exchange Security will cease to apply, the requirements requiring any such Initial Security or such Exchange Security issued to certain Holders be issued in global form will cease to apply, and a certificated Initial Security or Exchange Security or an Initial Security or Exchange Security in global form, in each case without restrictive transfer legends, will be available to the transferee of the Holder of such Initial Securities or Exchange Securities upon exchange of such transferring Holder’s certificated Initial Security or Exchange Security or directions to transfer such Holder’s interest in the Global Security, as applicable.

11

(iv) Upon the consummation of a Registered Exchange Offer with respect to the Initial Securities, all requirements pertaining to such Initial Securities that Initial Securities issued to certain Holders be issued in global form will still apply with respect to Holders of such Initial Securities that do not exchange their Initial Securities, and Exchange Securities in certificated or global form, in each case without the restricted securities legend set forth in Exhibit A to the Indenture will be available to Holders that exchange such Initial Securities in such Registered Exchange Offer.

(f) Cancellation or Adjustment of Global Security At such time as all beneficial interests in a Global Security have either been exchanged for Definitive Securities, redeemed, purchased, converted or canceled, such Global Security shall be returned to the Depository for cancellation or retained and canceled by the Trustee. At any time prior to such cancellation, if any beneficial interest in a Global Security is exchanged for certificated Securities, redeemed, purchased, converted or canceled, the principal amount of Securities represented by such Global Security shall be reduced and an adjustment shall be made on the books and records of the Trustee (if it is then the Securities Custodian for such Global Security) with respect to such Global Security, by the Trustee or the Securities Custodian, to reflect such reduction.

(g) No Obligation of the Trustee

(i) The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Security, a member of, or a participant in the Depository or other Person with respect to the accuracy of the records of the Depository or its nominee or of any participant or member thereof, with respect to any ownership interest in the Securities or with respect to the delivery to any participant, member, beneficial owner or other Person (other than the Depository) of any notice (including any notice of redemption) or the payment of any amount, under or with respect to such Securities. All notices and communications to be given to the Holders and all payments to be made to Holders under the Securities shall be given or made only to or upon the order of the registered Holders (which shall be the Depository or its nominee in the case of a Global Security). The rights of beneficial owners in any Global Security shall be exercised only through the Depository subject to the applicable rules and procedures of the Depository. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depository with respect to its members, participants and any beneficial owners.

12

(ii) Neither the Trustee nor the Registrar shall have any obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among Depository participants, members or beneficial owners in any Global Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

2.4 Definitive Securities

(c) Subject to the provisions of Section 2.1(b) hereof, the registered Holder of a Global Security shall be entitled to grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the applicable Securities.

13

(d) In the event of the occurrence of one of the events specified in Section 2.4(a) hereof, the Company shall promptly make available to the Trustee a reasonable supply of Definitive Securities in definitive, fully registered form without interest coupons. In the event that such Definitive Securities are not issued, the Company expressly acknowledges, with respect to the right of any Holder to pursue a remedy pursuant to Section 6.6 of this Indenture, the right of any beneficial owner of Securities to pursue such remedy with respect to the portion of the Global Security that represents such beneficial owner’s Securities as if such Definitive Securities had been issued.

13.0% Convertible Note Due 2017

1 Interest

TransAtlantic Petroleum Ltd., a Bermuda exempted company with limited liability (such company, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises to pay interest on the unpaid principal amount of this Security at the lesser of the rate per annum shown above and the maximum nonusurious interest rate permitted under applicable law. The Company will pay interest semiannually on January 1 and July 1 of each year, commencing July 1, 2015. Interest on the Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid on this Security, from the date of issuance of this Security. Interest will be computed on the basis of a 360-day year of twelve 30-day months. The Company agrees to pay interest in respect of overdue principal, and overdue interest, at a rate per annum equal to the lesser of 15.0% per annum and the maximum nonusurious interest rate permitted under applicable law.

2 Method of Payment

The Company will pay interest on the Securities (except defaulted interest) to the Persons who are registered holders of Securities at the close of business on the Regular Record Date next preceding the Interest Payment Date even if Securities are canceled after the Regular Record Date and on or before the Interest Payment Date. Holders must surrender Securities to a Paying Agent to collect principal payments. The Company will pay principal and interest in money of the United States dollars. Payments in respect of the Securities represented by a Global Security (including principal, premium and interest) will be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company. The Company will make all payments in respect of a certificated Security (including principal, premium and interest) by mailing a check to the registered address of each Holder thereof; provided, however, that payments on a certificated Security will be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

3 Paying Agent and Registrar

Initially, U.S. Bank National Association, a national banking association (the “Trustee”), will act as Paying Agent and Registrar. The Company may appoint and change any Paying Agent, Registrar or co-registrar without notice. The Company may act as Paying Agent, Registrar or co-registrar.

4 Indenture

The Company issued the Securities under an Indenture dated as of February 20, 2015, as such may be amended or supplemented from time to time (the “Indenture”), between the Company and the Trustee. The terms of the Securities include those stated in the Indenture and

7

those made part of the Indenture by reference to the Trust Indenture Act. Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all such terms, and Securityholders are referred to the Indenture and the Trust Indenture Act for a statement of those terms.

The Securities are general unsecured obligations of the Company. The Company shall be entitled to issue Additional Securities pursuant to Section 2.13 of the Indenture.
