ISSUE, DESCRIPTION, EXECUTION, REGISTRATION AND EXCHANGE OF NOTES

Section 2.01. Scope of Supplemental Indenture. This Supplemental Indenture amends and supplements the provisions of the Base Indenture, to which provisions reference is hereby made. The changes, modifications and supplements to the Base Indenture effected by this Supplemental Indenture shall be applicable only with respect to, and shall only govern the terms of, the Notes, which may be issued from time to time in accordance herewith, and shall not apply to any other Securities that may be issued under the Base Indenture unless a supplemental indenture with respect to such other Securities specifically incorporates such changes, modifications and supplements. For all purposes under the Base Indenture, the Notes shall constitute a single series of Securities, and with regard to any matter requiring the consent under the Base Indenture of Securityholders of multiple series of Securities voting together as a single class, the consent of Holders of the Notes voting as a separate class shall also be required and the same threshold shall apply. The provisions of this Supplemental Indenture shall supersede, with respect to the Notes, any conflicting provisions in the Base Indenture.

Section 2.02. Designation and Amount. The Notes are hereby created and authorized as a single series of Securities under the Base Indenture. The Notes shall be designated as the “5.75% Convertible Senior Notes due 2021.” The aggregate principal amount of Notes that may be authenticated and delivered under the Indenture is initially limited to $50,000,000 (as increased by an amount equal to the aggregate principal amount of any additional Notes purchased by the Underwriters pursuant to the exercise of their over-allotment option as set forth in the Underwriting Agreement), subject to Section 2.09 and except for Notes authenticated and delivered upon registration or transfer of, or in exchange for, or in lieu of other Notes to the extent expressly permitted hereunder.

Section 2.03. Form of Notes. The Notes and the Trustee’s certificate of authentication to be borne by such Notes shall be substantially in the respective forms set forth in Exhibit A, the terms and provisions of which shall constitute, and are hereby expressly incorporated in and made a part of the Indenture. To the extent applicable, the Company and the Trustee, by their execution and delivery of the Indenture, expressly agree to such terms and provisions and to be bound thereby.

Any Global Note may be endorsed with or have incorporated in the text thereof such legends or recitals or changes not inconsistent with the provisions of the Indenture as may be required by the Custodian or the Depositary, or as may be required to comply with any applicable law or any regulation thereunder or with the rules and regulations of any securities exchange or automated quotation system upon which the Notes may be listed, quoted or traded or designated for issuance or to conform with any usage with respect thereto, or to indicate any special limitations or restrictions to which any particular Notes are subject.

Any of the Notes may have such letters, numbers or other marks of identification and such notations, legends or endorsements as any Officer executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of the Indenture, or as may be required to comply with any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any securities exchange or automated quotation system on which the Notes may be listed, quoted or designated for issuance, or to conform to usage or to indicate any special limitations or restrictions to which any particular Notes are subject.

(c) Any Defaulted Amounts shall forthwith cease to be payable to the Holder on the relevant payment date but shall accrue interest per annum at the rate borne by the Notes, subject to the enforceability thereof under applicable law, from, and including, such relevant payment date, and such Defaulted Amounts together with such interest thereon shall be paid by the Company, at its election in each case, as provided in clause (i) or (ii) below:

(i) The Company may elect to make payment of any Defaulted Amounts 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 Amounts, which shall be fixed in the following manner. The Company shall notify the Trustee in writing in an Officer’s Certificate of the amount of the Defaulted Amounts proposed to be paid on each Note and the date of the proposed payment (which shall be not less than 25 calendar days after the receipt by the Trustee of such notice, unless the Trustee shall consent to an earlier date), and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount to be paid in respect of such Defaulted Amounts 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 Amounts as in this clause provided. Thereupon the Company shall fix a special record date for the payment of such Defaulted Amounts which shall be not more than 15 calendar days and not less than 10 calendar days prior to the date of the proposed payment, and not less than 10 calendar days after the receipt by the Trustee of the notice of the proposed payment. The Company shall promptly notify the Trustee in writing of such special record date and in such notice, instruct the Trustee, in the name and at the expense of the Company, to deliver notice of the proposed payment of such Defaulted Amounts and the special record date therefor to each Holder electronically (in the case of Global Notes) or mailed, first class postage prepaid at such Holder’s address as it appears in the Security Register (in the case of Notes that are not Global Notes), not less than 10 calendar days prior to such special record date. Notice of the proposed payment of such Defaulted Amounts and the special record date therefor having been so delivered, such Defaulted Amounts shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on such special record date and shall no longer be payable pursuant to the following clause (ii) of this Section 2.04(c).

(ii) The Company may make payment of any Defaulted Amounts 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.

Such certificate by the Trustee (or such an Authenticating Agent) upon any Note executed by the Company shall be conclusive evidence that the Note so authenticated has been duly authenticated and delivered hereunder and that the Holder is entitled to the benefits of the Indenture.

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

(a) Notwithstanding anything in the Base Indenture to the contrary, none of the Company, the Trustee, the Security Registrar or any co-Security 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 or (ii) any Notes, or a portion of any Note, surrendered for repurchase (and not withdrawn) in accordance with Article 15.

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

(b) So long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law, subject to the second paragraph from the end of Section 2.06(c) all Notes shall be represented by one or more Notes in global form (each, a “Global Note”) registered in the name of the Depositary or the nominee of the Depositary. Each Global Note shall bear the legend required on a Global Note set forth in Exhibit A hereto. The transfer and exchange of beneficial interests in a Global Note that does not involve the issuance of a Physical Note shall be effected through the Depositary (but not the Trustee or the Custodian) in accordance with the Indenture (including the restrictions on transfer set forth herein) and the procedures of the Depositary therefor.

(c) As used in this Section 2.06(c), the term “transfer” encompasses any sale, pledge, transfer or other disposition whatsoever of any Restricted Security. Notwithstanding any other provisions of the Indenture (other than the provisions set forth in this Section 2.06(c)), a Global

Note may not be transferred as a whole or in part except (i) by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary and (ii) for exchange of a Global Note or a portion thereof for one or more Physical Notes in accordance with the second immediately succeeding paragraph.

Initially, each Global Note shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for Cede & Co.

At such time as all interests in a Global Note have been converted, canceled, repurchased, redeemed or transferred, such Global Note shall be, upon receipt thereof, canceled by the Trustee in accordance with standing procedures and existing instructions between the Depositary and the Custodian. At any time prior to such cancellation, if any interest in a Global Note is exchanged for Physical Notes, converted, canceled, repurchased, redeemed or transferred to a transferee who receives Physical Notes therefor or any Physical 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 Trustee, to reflect such reduction or increase.

None of the Company, the Trustee or any agent of the Company or the Trustee shall have any responsibility or liability for any aspect of the records relating to or payments made by the Depositary on account of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

If (i) the Depositary notifies the Company at any time that the Depositary is unwilling or unable to continue as depositary for the Global Notes and a successor depositary is not appointed within 90 calendar days, (ii) the Depositary ceases to be registered as a clearing agency under the Exchange Act and a successor depositary is not appointed within 90 calendar days or (iii) an Event of Default with respect to the Notes has occurred and is continuing and a beneficial owner of any Note requests that its beneficial interest therein be exchanged for a Physical Note, the Company shall execute, and the Trustee, upon receipt of an Officer’s Certificate, an Opinion of Counsel and a Company Order for the authentication and delivery of Notes, shall authenticate and deliver (x) in the case of clause (iii), a Physical Note to such beneficial owner in a principal amount equal to the principal amount of such Note corresponding to such beneficial owner’s beneficial interest and (y) in the case of clause (i) or (ii), Physical Notes to each beneficial owner of the related Global Notes (or a portion thereof) in an aggregate principal amount equal to the aggregate principal amount of such Global Notes in exchange for such Global Notes, and upon delivery of the Global Notes to the Trustee such Global Notes shall be canceled.

Physical Notes issued in exchange for all or a part of the Global Note pursuant to this Section 2.06(d) 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, or, in the case of clause (iii) of the immediately preceding paragraph, the relevant beneficial owner, shall instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such Physical Notes to the Persons in whose names such Physical Notes are so registered.

(e) Any Note or Common Stock issued upon the conversion or exchange of a Note that is repurchased or owned by any Affiliate of the Company (or any Person who was an Affiliate of the Company at any time during the three months preceding) may not be resold by such Affiliate (or such Person, as the case may be) unless registered under the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities Act in a transaction that results in such Note or Common Stock, as the case may be, no longer being a “restricted security” (as defined under Rule 144 under the Securities Act). The Company shall cause any Note that is repurchased (other than notes repurchased pursuant to cash-settled swaps or other derivatives) or owned by it to be surrendered to the Trustee for cancellation in accordance with Section 2.07.

Section 2.07. Cancellation of Notes Paid, Converted, Etc. The Company shall cause all Notes surrendered for the purpose of payment, repurchase (including as described in Section 2.09, but excluding Notes repurchased pursuant to cash-settled swaps or other derivatives), redemption, registration of transfer or exchange or conversion, if surrendered to any Person other than the Trustee (including any of the Company’s agents, Subsidiaries or Affiliates), to be surrendered to the Trustee for cancellation pursuant to Section 2.08 of the Base Indenture. All Notes delivered to the Trustee shall be canceled promptly by it in accordance with its customary procedures, and, except for Notes surrendered for registration of transfer or exchange, no Notes shall be authenticated in exchange thereof except as expressly permitted by any of the provisions of the Indenture. The Trustee shall dispose of canceled Notes in accordance with its customary procedures. After such cancellation and at the Company’s written request in a Company Order, shall deliver a certificate of such cancellation to the Company.

Section 2.08. CUSIP Numbers. The Company in issuing the Notes may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in all notices issued to Holders as a convenience to such Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or on such notice and that reliance may be placed only on the other identification numbers printed on the Notes. The effectiveness of any such notice shall not be affected by any defect in, or omission of, such “CUSIP” numbers. The Company shall promptly notify the Trustee in writing of any change in the “CUSIP” numbers.

Section 2.09. Additional Notes; Repurchases. The Company may, without the consent of the Holders and notwithstanding Section 2.02, reopen the Indenture and issue additional Notes under the Indenture with the same terms as the Notes initially issued hereunder (except for any differences in issue date, issue price and interest accrued, if any) in an unlimited aggregate principal amount; provided that if any such additional Notes are not fungible with the Notes initially issued hereunder for U.S. federal income tax and securities law purposes, such

additional Notes shall have a separate CUSIP number. Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order, an Officer’s Certificate and an Opinion of Counsel, such Officer’s Certificate and Opinion of Counsel to cover such matters, in addition to those required by Section 13.07 of the Base Indenture, as the Trustee shall reasonably request. In addition, the Company may, to the extent permitted by law, and directly or indirectly (regardless of whether such Notes are surrendered to the Company), repurchase Notes in the open market or otherwise, whether by the Company or its Subsidiaries or through a private or public tender or exchange offer or through counterparties to private agreements, including by cash-settled swaps or other derivatives, in each case without prior notice to the Holders. The Company shall cause any Notes so repurchased (other than Notes repurchased pursuant to cash-settled swaps or other derivatives) to be surrendered to the Trustee for cancellation in accordance with Section 2.07, and such Notes shall no longer be considered Outstanding hereunder upon their repurchase.

ARTICLE 4

PARTICULAR COVENANTS OF THE COMPANY

Section 4.01. Payment of Principal and Interest. This Section 4.01 shall supersede Section 4.01 of the Base Indenture and all references in the Base Indenture to Section 4.01 thereof shall be deemed, for the purposes of the Notes, to be references to this Section 4.01. The Company covenants and agrees that it will pay or cause to be paid the principal (including the Redemption Price or the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, each of the Notes at the places, at the respective times and in the manner provided herein and in the Notes.

Section 4.02. Maintenance of Office or Agency. The Company will maintain in the continental United States of America an office or agency where the Notes may be surrendered for registration of transfer or exchange or for presentation for payment or repurchase (the “Paying Agent”) or for conversion (the “Conversion Agent”). The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such offices or agencies. If at any time the Company shall fail to maintain any required office or agency with respect to the presentment or surrender of the Notes or shall fail to furnish the Trustee with the address thereof, such presentations and surrenders may be made or served at the Corporate Trust Office or another office or agency of the Trustee as designated by the Trustee.

The Company may also from time to time designate as co-Security Registrars one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the continental United States of America for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. The terms “Paying Agent” and “Conversion Agent” include any such additional or other offices or agencies, as applicable.

The Company hereby initially designates the Trustee as the Paying Agent, Security Registrar, Custodian and Conversion Agent and the Corporate Trust Office as the office or agency in the continental United States of America where Notes may be surrendered for registration of transfer or exchange or for presentation for payment or repurchase or for conversion.

Section 4.03. Provisions as to Paying Agent. (a) Section 4.03(a)(3) of the Base Indenture is hereby amended with respect to the Notes by replacing Section 4.03(a)(3) in its entirety with the following: “that at any time during the continuance of an Event of Default, upon request of the Trustee, it will forthwith pay to the Trustee all sums so held in trust; and”.

Notwithstanding anything in the Base Indenture to the contrary, the Company shall, on or before each due date of the principal (including the Redemption Price or the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, the Notes, deposit with the Paying Agent a sum sufficient to pay such principal (including the Redemption Price or the Fundamental Change Repurchase Price, if applicable) or accrued and unpaid interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee in writing of any failure to take such action; provided that if such deposit is made on the due date, such deposit must be received by the Paying Agent by 11:00 a.m., New York City time, on such date.

(a) Notwithstanding anything in the Base Indenture to the contrary, if the Company shall act as its own Paying Agent, it will, on or before each due date of the principal (including the Redemption Price or the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, the Notes, set aside, segregate and hold in trust for the benefit of the Holders of the Notes a sum sufficient to pay such principal (including the Redemption Price or the Fundamental Change Repurchase Price, if applicable) and accrued and unpaid interest so becoming due and will promptly notify the Trustee in writing of any failure to take such action and of any failure by the Company to make any payment of the principal (including the Redemption Price or the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, the Notes when the same shall become due and payable.

(b) Anything in this Section 4.03 or the Base Indenture to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a satisfaction and discharge of the Indenture, or for any other reason, pay, cause to be paid or deliver to the Trustee all sums or amounts held in trust by the Company or any Paying Agent hereunder as required by this Section 4.03, such sums or amounts to be held by the Trustee upon the trusts herein contained and upon such payment or delivery by the Company or any Paying Agent to the Trustee, the Company or such Paying Agent shall be released from all further liability but only with respect to such sums or amounts.

(c) Notwithstanding anything in the Base Indenture to the contrary, any money and shares of Common Stock deposited with the Trustee, the Conversion Agent or any Paying Agent, or then held by the Company, in trust for the payment of the principal (including the Redemption Price or the Fundamental Change Repurchase Price, if applicable) of, accrued and unpaid interest on and the consideration due upon conversion of any Note and remaining unclaimed for two years after such principal (including the Redemption Price or the Fundamental Change Repurchase Price, if applicable), interest or consideration due upon conversion has become due and payable shall be paid to the Company on request of the Company contained in an Officer’s Certificate, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee, the Conversion Agent or such Paying Agent with respect to such trust money and shares of Common Stock, and all liability of the Company as trustee thereof, shall thereupon cease.

Section 4.04. Existence. Subject to Article 11, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence.

Section 4.05. Annual Reports. (a) The Company shall file with the Trustee, within 15 days after the same are required to be delivered or filed with the Commission (giving effect to any grace period provided by Rule 12b-25 under the Exchange Act or any successor rule under the Exchange Act), copies of any documents or reports that the Company is required to deliver or file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act (excluding, for the avoidance of doubt, any information, documents or reports, or portions thereof, that are subject to confidential treatment, and any correspondence with the Commission). Any such document or report that the Company files with the Commission via the Commission’s EDGAR system (or any successor thereto) shall be deemed to be filed with the Trustee for purposes of this Section 4.05(a) at the time such documents are filed via the EDGAR system (or any successor thereto); provided, however, that the Trustee shall have no obligation whatsoever to determine whether or not such information, documents or reports have been filed to the EDGAR system (or any successor thereto). Section 5.03(a) of the Base Indenture shall, with respect to the Notes, be superseded in its entirety by this Section 4.05(a), and any reference in the Base Indenture to such Section 5.03(a) shall, with respect to the Notes, be deemed to refer instead to this Section 4.05(a).

(b) Delivery of the information, documents and reports described in subsection (a) above to the Trustee is for informational purposes only, and the Trustee’s receipt of the foregoing shall not constitute constructive notice of any information contained therein, or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to conclusively rely on an Officer’s Certificate). The Trustee shall not be obligated to monitor or confirm, on a continuing basis or otherwise, the Company’s or any other Person’s compliance with this Section 4.05 or with respect to any reports or other documents filed under the Indenture. Section 5.03(b) of the Base Indenture shall, with respect to the Notes, be superseded in its entirety by this Section 4.05(b), and any reference in the Base Indenture to such Section 5.03(b) shall, with respect to the Notes, be deemed to refer instead to this Section 4.05(b).

Section 4.06. Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law that would prohibit or forgive the Company from paying all or any portion of the principal of or interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or that may affect the covenants or the performance of the Indenture; and the Company (to the extent it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

Section 4.07. Compliance Certificate; Statements as to Defaults. The Company shall deliver to the Trustee within 120 calendar days after the end of each fiscal year of the Company (beginning with the fiscal year ending on December 31, 2016) an Officer’s Certificate indicating whether the signer thereof knows of any Default that occurred during the previous year and specifying the nature thereof.

In addition, the Company shall deliver to the Trustee, as soon as possible, and in any event within 30 calendar days after the occurrence of any Event of Default or Default, an Officer’s Certificate setting forth the details of such Event of Default or Default, its status and the action that the Company is taking or proposing to take in respect thereof.

Section 13.12 of the Base Indenture shall, with respect to the Notes, be superseded in its entirety by this Section 4.07, and any reference in the Base Indenture to such Section 13.12 shall, with respect to the Notes, be deemed to refer instead to this Section 4.07.

Section 4.08. Further Instruments and Acts. Upon request of 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 the Indenture.

Section 4.09. Limitation on Incurrence of Additional Indebtedness. For so long as any Notes are Outstanding, the Company will not, nor will it permit any of its Subsidiaries to, directly or indirectly, incur any Indebtedness other than Permitted Debt.

The accrual of interest, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of preferred stock as Indebtedness due to a change in accounting principles, and the payment of dividends on Redeemable Equity in the form of additional shares of the same class of Redeemable Equity will not be deemed to be an incurrence of Indebtedness for purposes of this Section 4.09. For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S. dollar equivalent principal amount of Indebtedness denominated in a foreign currency shall be utilized, calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred (or, in the case of revolving indebtedness, on the date such Indebtedness was first committed); provided, that if any such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. Notwithstanding any other provision of this covenant, the maximum amount of Indebtedness that the Company or any of its Subsidiaries may incur pursuant to this Section 4.09 shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values.

Section 4.10. Effectiveness of Covenants. Following the occurrence of a Fundamental Change described in clause (a) or (b) of the definition thereof or at such time as less than 25% of the initial aggregate principal amount of the Notes (including Notes, if any, issued pursuant to the exercise of the Underwriters’ option to purchase additional Notes granted under the Underwriting Agreement) remain Outstanding, the covenants set forth in Section 4.09, shall cease to apply to the Company and its Subsidiaries.

ARTICLE 6

DEFAULTS AND REMEDIES

Section 6.01. Applicability of Article 6 of the Base Indenture. Article 6 of the Base Indenture shall not apply to the Notes. Instead, the provisions set forth in this Article 6 shall, with respect to the Notes, supersede in its entirety Article 6 of the Base Indenture, and all references in the Base Indenture to Article 6 thereof and the provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to this Article 6 and the applicable provisions set forth in this Article 6, respectively. Without limiting the forgoing, all references in Section 7.06 of the Base Indenture to Section 6.01(a)(4) or (5) of the Base Indenture shall, with respect to the Notes, be deemed to be references to Section 6.02(i) or Section 6.02(j) hereof, respectively.

stated maturity or (ii) constituting a failure to pay the principal or interest of any such debt when due and payable (after the expiration of all applicable grace periods) at its stated maturity, upon required repurchase, upon declaration of acceleration or otherwise, and such acceleration shall not have been rescinded or annulled or such failure to pay shall not have been cured, as the case may be, within 30 days after written notice to the Company by the Trustee or to the Company and the Trustee by Holders of at least 25% in aggregate principal amount of the Notes then Outstanding determined in accordance with Section 8.04 of the Base Indenture has been received;

(h) a final judgment or judgments for the payment of $7,500,000 (or the foreign currency equivalent thereof) or more (excluding any amounts covered by insurance) in the aggregate rendered against the Company and/or any Significant Subsidiary of the Company, which judgment is not discharged or stayed within 60 days after (i) the date on which the right to appeal thereof has expired if no such appeal has commenced, or (ii) the date on which all rights to appeal have been extinguished;

(i) the Company or any Significant Subsidiary shall commence a voluntary case or other proceeding seeking liquidation, reorganization or other relief with respect to the Company or any such Significant Subsidiary or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company or any such Significant Subsidiary or any substantial part of its property, or shall consent to any such relief or to the appointment of or taking possession by any such official in an involuntary case or other proceeding commenced against it, or shall make a general assignment for the benefit of creditors, or shall fail generally to pay its debts as they become due; or

(j) an involuntary case or other proceeding shall be commenced against the Company or any Significant Subsidiary seeking liquidation, reorganization or other relief with respect to the Company or such Significant Subsidiary or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company or such Significant Subsidiary or any substantial part of its property, and such involuntary case or other proceeding shall remain undismissed and unstayed for a period of 60 consecutive calendar days.

Section 6.03. Acceleration; Rescission and Annulment. If 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 an Event of Default specified in Section 6.02(i) or Section 6.02(j) with respect to the Company), unless the principal of all of the Notes shall have already become due and payable, either the Trustee, by notice in writing to the Company, or the Holders of at least 25% in aggregate principal amount of the Notes then Outstanding determined in accordance with Section 8.04 of the Base Indenture, by notice in writing to the Company and to the Trustee, may, and the Trustee at the written direction of such Holders shall, declare 100% of the principal amount of, and accrued and unpaid interest on, all the Notes then Outstanding to be due and payable immediately, and upon any such declaration the same shall become and shall automatically be immediately due and payable,

anything contained in the Indenture or in the Notes to the contrary notwithstanding. If an Event of Default specified in Section 6.02(i) or Section 6.02(j) with respect to the Company occurs and is continuing, 100% of the principal amount of, and accrued and unpaid interest, if any, on, all Notes then Outstanding shall automatically become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder of Notes.

The immediately preceding paragraph, 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 (or have become immediately 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, if (1) the Company shall have paid or deposited with the Trustee a sum sufficient to pay all matured installments of accrued and unpaid interest upon the Notes and the principal of any and all Notes that shall have become due otherwise than by acceleration (with interest on such principal and, to the extent that such payment is enforceable under applicable law, on overdue installments of accrued and unpaid interest, at the rate borne by the Notes at such time to the date of such payment or deposit) and amounts due to the Trustee pursuant to Section 7.06 of the Base Indenture, (2) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (3) any and all existing Events of Default under the Indenture, other than the nonpayment of the principal of and accrued and unpaid interest, if any, on Notes that shall not have become due by their terms, shall have been remedied or waived pursuant to Section 6.10, then and in every such case (except as provided in the immediately succeeding sentence) 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 and rescind and annul such declaration and its consequences and such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of the 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 to the contrary herein, no such waiver or rescission and annulment shall extend to or shall affect any Default or Event of Default resulting from (i) the nonpayment of the principal (including the Redemption Price or the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest, if any, on, any Notes, (ii) a failure to repurchase any Notes when required or (iii) a failure to pay or deliver, as the case may be, the consideration due upon conversion of the Notes.

Section 6.04. Additional Interest. Notwithstanding anything in the Indenture or in the Notes to the contrary, to the extent the Company elects, the sole remedy for an Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.05(a) and for any failure to comply with the requirements of Section 314(a)(1) of the Trust Indenture Act, shall (i) for the first 90 calendar days after the occurrence of such an Event of Default (beginning on, and including, the date on which such an Event of Default first occurs), consist exclusively of the right to receive Additional Interest on the Notes at a rate equal to 0.25% per annum of the principal amount of the Notes Outstanding for each day during such 90- calendar day period on which such an Event of Default is continuing and (ii) for the period from, and including, the 91st calendar day after the occurrence of such an Event of Default to, and including, the 180th calendar day after the occurrence of such an Event of Default, consist exclusively of the right to receive Additional Interest on the Notes at a rate equal to 0.50% per

annum of the principal amount of Notes Outstanding for each day during such additional 90- calendar day period on which such an Event of Default is continuing. In no event shall Additional Interest described in this paragraph accrue at a rate in excess of 0.50% per annum, regardless of the number of events or circumstances giving rise to the requirement to pay such Additional Interest. If the Company so elects, such Additional Interest shall be payable in the same manner and on the same dates as the stated interest payable on the Notes. On the 181st calendar day after such Event of Default (if the Event of Default relating to the Company’s failure to file is not cured or waived prior to such 181st calendar day), the Notes shall be immediately subject to acceleration as provided in Section 6.03. The provisions of this paragraph will not affect the rights of Holders of Notes in the event of the occurrence of any Event of Default other than the Company’s failure to comply with its obligations as set forth in Section 4.05(a) or the failure to comply with the requirements of Section 314(a)(1) of the Trust Indenture Act. In the event the Company does not elect to pay Additional Interest following an Event of Default in accordance with this Section 6.04 or the Company elected to make such payment but does not pay the Additional Interest when due, the Notes shall be immediately subject to acceleration as provided in Section 6.03.

In order to elect to pay Additional Interest as the sole remedy during the first 180 calendar days after the occurrence of any Event of Default described in the immediately preceding paragraph, the Company must notify all Holders of the Notes, the Trustee and the Paying Agent (if other than the Trustee) in an Officer’s Certificate of such election prior to the beginning of such 180-calendar day period. Upon the failure to timely give such notice or pay Additional Interest, the Notes shall be immediately subject to acceleration as provided in Section 6.03.

The Trustee shall not at any time be under any duty or responsibility to any Holder of Notes to determine the Additional Interest, or with respect to the nature, extent, or calculation of the amount of Additional Interest owed, or with respect to the method employed in such calculation of the Additional Interest.

Section 6.05. Payments of Notes on Default; Suit Therefor. If an Event of Default described in clause (a) or (b) of Section 6.02 shall have occurred, the Company shall, upon demand of the Trustee or the requisite Holders as set forth in Section 6.03, pay to the Trustee, for the benefit of the Holders of the Notes, the whole amount then due and payable on the Notes for principal and interest, if any, with interest on any overdue principal and 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 7.06 of the Base Indenture. 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 6.05, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal and accrued and unpaid interest, 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, and disbursements of the Trustee, its agents and counsel) and of the Holders 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 to the Trustee under Section 7.06 of the Base Indenture; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Holders 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 Holders, to pay to the Trustee any amount due it for reasonable compensation, expenses, and disbursements, including agents and counsel fees, and including any other amounts due to the Trustee under Section 7.06 of the Base Indenture, incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, 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 Holder any plan of reorganization, arrangement, adjustment or composition affecting such Holder or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

All rights of action and of asserting claims under the 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, and disbursements 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 the 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.

In case the Trustee shall have proceeded to enforce any right under the Indenture and such proceedings shall have been discontinued or abandoned because of any waiver pursuant to Section 6.10 or any rescission and annulment pursuant to Section 6.03 or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the Holders 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 Holders and the Trustee shall continue as though no such proceeding had been instituted.

Section 6.06. Application of Monies Collected by Trustee. Any monies collected by the Trustee pursuant to this Article 6 with respect to the Notes shall be applied in the following order, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the several Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid:

First, to the payment of all amounts due the Trustee and its agents under the Base Indenture;

Second, in case the principal of the Outstanding Notes shall not have become due and be unpaid, to the payment of interest on, and any cash due upon conversion of, the Notes in default in the order of the date due of the payments of such interest and cash due upon conversion, as the case may be, with interest (to the extent that such interest has been collected by the Trustee) upon such overdue payments 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, if applicable, the payment of the Redemption Price or the Fundamental Change Repurchase Price and any cash due upon conversion) then owing and unpaid upon the Notes for principal and interest, if any, with interest on the overdue principal 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 (including, if applicable, the Redemption Price or the Fundamental Change Repurchase Price and any cash due upon conversion) and interest without preference or priority of principal over interest, or of interest over principal or of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate of such principal (including, if applicable, the Redemption Price or the Fundamental Change Repurchase Price and any cash due upon conversion) and accrued and unpaid interest; and

Section 6.07. Proceedings by Holders. Except to enforce the right to receive payment of principal (including, if applicable, the Redemption Price or the Fundamental Change Repurchase Price) or interest when due, or the right to receive payment or delivery of the consideration due upon conversion, no Holder shall have any right by virtue of or by availing of any provision of the Indenture or a Note to institute any suit, action or proceeding, judicial or otherwise, in equity or at law upon or under or with respect to the Indenture or a Note, or for the appointment of a receiver, trustee, liquidator, custodian or other similar official, or for any other remedy hereunder, unless:

(a) such Holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as herein provided;

(b) Holders of at least 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;

(c) such Holders shall have offered to the Trustee such security or indemnity satisfactory to it against all losses, liability and expenses to be incurred therein or thereby;

(d) the Trustee for 60 calendar days after its receipt of such notice, request and offer of such security or indemnity, shall have neglected or refused to institute any such action, suit or proceeding; and

(e) 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 of the aggregate principal amount of the Notes then Outstanding within such 60-calendar day period pursuant to Section 6.10,

it being understood and intended, and being expressly covenanted by the taker and Holder of every Note with every other taker and Holder and the Trustee that no one or more Holders shall have any right in any manner whatever by virtue of or by availing of any provision of the Indenture to affect, disturb or prejudice the rights of any other Holder (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 Holders), or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under the Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders (except as otherwise provided herein). For the protection and enforcement of this Section 6.07, each and every Holder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

Notwithstanding any other provision of the Indenture and any provision of any Note, the right of any Holder to receive payment or delivery, as the case may be, of (x) the principal (including the Redemption Price or the Fundamental Change Repurchase Price, if applicable) of, (y) accrued and unpaid interest, if any, on, and (z) the consideration due upon conversion of, such Note, on or after the respective due dates expressed or provided for in such Note or in the Indenture, or to bring suit for the enforcement of any such payment or delivery, as the case may be, on or after such respective dates against the Company shall not be impaired or affected without the consent of such Holder.

Section 6.08. 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 the 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 the Indenture or in aid of the exercise of any power granted in the Indenture, or to enforce any other legal or equitable right vested in the Trustee by the Indenture or by law.

Section 6.09. Remedies Cumulative and Continuing. Except as provided in the last paragraph of Section 2.07 of the Base Indenture, all powers and remedies given by this Article 6 to the Trustee or to the Holders 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 the 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 Event of Default or any acquiescence therein; and, subject to the provisions of Section 6.07, every power and remedy given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Holders.

Section 6.10. Direction of Proceedings and Waiver of Defaults by Majority of Holders. Subject to the Trustee’s right to request security or indemnity from the relevant Holders as described herein, the Holders of at least a majority of the aggregate principal amount of the Notes at the time Outstanding determined in accordance with Section 8.04 of the Base Indenture 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 the Notes; provided, however, that (a) such direction shall not be in conflict with any rule of law or with the 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, subject to the Trustee’s duties under the Trust Indenture Act, 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 at least a majority in aggregate principal amount of the Notes at the time Outstanding determined in accordance with Section 8.04 of the Base Indenture may on behalf of the Holders of all of the Notes waive (with written notice to the Trustee) any past Default or Event of Default hereunder and its consequences except (i) a default in the payment of accrued and unpaid interest, if any, on, or the principal (including any Redemption Price or the Fundamental Change Repurchase Price) of, the Notes when due that has not been cured pursuant to the provisions of Section 6.02, (ii) a failure by the Company to pay or deliver, as the case may be, the consideration due upon conversion of the Notes, (iii) a failure by the Company to repurchase any Notes when required under the Indenture or (iv) a default in respect of a covenant or provision hereof which under Article 10 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 6.10, said Default or Event of Default shall for all purposes of the Notes and the Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

Section 6.11. Notice of Defaults. Trustee shall, within 90 calendar days after the occurrence and continuance of a Default of which a Responsible Officer has actual knowledge, deliver to all Holders notice of all Defaults actually known to a Responsible Officer electronically (in the case of Global Notes) or in the manner and to the extent provided in Section 313(c) of the Trust Indenture Act (in the case of Notes that are not Global Notes), unless such Defaults shall have been cured or waived before the giving of such notice; provided that, except in the case of a Default in the payment of the principal of (including the Redemption Price or the Fundamental Change Repurchase Price, if applicable), or accrued and unpaid interest on, any of the Notes or a Default in the payment or delivery of the consideration due upon conversion, the Trustee shall be fully protected in withholding such notice if and so long as the Trustee in good faith determines that the withholding of such notice is in the interests of the Holders. This Section 6.11 shall supersede Section 7.14 of the Base Indenture, and any reference in the Base Indenture to such Section 7.14 thereof shall be deemed to refer instead to this Section 6.11. The proviso set forth in Section 315(b) of the Trust Indenture Act shall not apply with respect to the Notes.

Section 6.12. Undertaking to Pay Costs. All parties to the 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 the Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section 6.12 (to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Notes at the time Outstanding determined in accordance with Section 8.04 of the Base Indenture, or to any suit instituted by any Holder for the enforcement of the payment of the principal of or accrued and unpaid interest, if any, on any Note (including, but not limited to, the Redemption Price or the Fundamental Change Repurchase Price, if applicable) 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, or receive the consideration due upon conversion, in accordance with the provisions of Article 14.

Upon the written request of the Company, the Trustee is hereby authorized to join with the Company in the execution of any such supplemental indenture, to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to, but may in its discretion, enter into any supplemental indenture that affects the Trustee’s own rights, duties or immunities under the Indenture or otherwise.

The consent of Holders is not necessary under this Section 10.03 to approve the particular form of any proposed supplemental indenture. It shall be sufficient if such Holders approve the substance thereof.

Section 10.04. Effect of Supplemental Indentures. Upon the execution of any supplemental indenture pursuant to the provisions of this Article 10, the Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitation of rights, obligations, duties and immunities under the Indenture of the Trustee, the Company and the Holders shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of the Indenture for any and all purposes.

Section 10.05. Notation on Notes. Notes authenticated and delivered after the execution of any supplemental indenture pursuant to the provisions of this Article 10 may, at the Company’s expense, bear a notation as to any matter provided for in such supplemental indenture.

(a) Subject to this Section 14.02, Section 14.01(b), Section 14.03, Section 14.04 and Section 14.08(a), upon conversion of any Note, the Company shall deliver to the converting Holder, in respect of each $1,000 principal amount of Notes being converted a number of shares of Common Stock equal to the Conversion Rate (as adjusted for any Additional Shares as a result of a Voluntary Conversion Increase, if any), together with a cash payment, if applicable, in lieu of delivering any fractional share of Common Stock in accordance with subsection (j) of this Section 14.02, on the third Business Day immediately following the relevant Conversion Date. A Holder may convert fewer than all of such Holder’s Notes so long as the Notes converted are a multiple of $1,000 principal amount.

(b) Subject to Section 14.02(e), before any Holder of a Note shall be entitled to convert a Note as set forth above, such Holder shall provide an irrevocable notice (a “Notice of Conversion”) by (i) in the case of a Global Note, complying with the procedures of the Depositary in effect at that time and, if required, (1) paying funds equal to the interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 14.02(h) and (2) paying all transfer and similar taxes as set forth in Section 14.02(d) and Section 14.02(e) and (ii) in the case of a Physical Note (1) completing, manually signing and delivering the irrevocable written notice to the Conversion Agent as set forth in the Form of Notice of Conversion (or a facsimile thereof) at the office of the Conversion Agent and stating 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 shares of Common Stock to be delivered upon settlement of the Conversion Obligation to be registered, (2) surrendering 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, furnishing appropriate endorsements and transfer documents, (4) if required, paying funds equal to the interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 14.02(h) and (5) paying all transfer and similar taxes as set forth in Section

14.02(d) and Section 14.02(e). The Trustee (and if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this Article 14 on the Conversion Date for 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 Fundamental Change Repurchase Notice to the Company in respect of such Notes and has not validly withdrawn such Fundamental Change Repurchase Notice in accordance with Section 15.03.

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 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 subsection (b) above. The Company shall issue or cause to be issued, and deliver to the Conversion Agent or to such Holder, or such Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the full number of shares of Common Stock to which such Holder shall be entitled in satisfaction of the Company’s Conversion Obligation.

(d) In case any Physical 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 a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note, without payment of any service charge by the converting Holder but, if required by the Company, the Trustee or the Security Registrar, with payment of a sum sufficient to cover any documentary, stamp or similar issue or transfer tax or similar governmental charge required by law or that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such conversion being different from the name of the Holder of the old Notes surrendered for such conversion.

(e) If a Holder submits a Note for conversion, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue of any shares of Common Stock upon conversion, unless the tax is due because the Holder requests any such shares to be issued in a name other than the Holder’s name, in which case the Holder must pay that tax. The Conversion Agent may refuse to deliver the certificates representing the shares of Common Stock being issued in a name other than the Holder’s name until the Trustee receives a sum sufficient to pay any tax that is due by such Holder in accordance with the immediately preceding sentence.

(f) Except as provided in Section 14.05, no adjustment shall be made for dividends on any shares of Common Stock issued upon the conversion of any Note as provided in this Article 14.

(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 Holder shall not receive any separate cash payment for accrued and unpaid interest, if any, except as set forth below. The Company’s settlement of the full Conversion Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid interest, if any, to, but excluding, the relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but excluding, the relevant Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Notwithstanding the foregoing, if Notes are converted after the close of business on a Regular Record Date, Holders of such Notes as of the close of business on such Regular Record Date will receive the full amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. However, Notes surrendered for conversion during the period beginning after the close of business on any Regular Record Date and ending at the open of business on the immediately following Interest Payment Date must be accompanied by funds equal to the amount of interest payable on the Notes so converted; provided that no such payment shall be required (1) for Notes surrendered for conversion after the close of business on the Regular Record Date immediately preceding the Maturity Date; (2) if the Company has specified a Redemption Date that is after a Regular Record Date and on or prior to the second Business Day immediately following the corresponding Interest Payment Date; (3) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the second Business Day immediately following the corresponding Interest Payment Date; or (4) to the extent of any Defaulted Amounts, if any Defaulted Amounts exists at the time of conversion with respect to such Note. Therefore, for the avoidance of doubt, all Holders of record at the close of business on the Regular Record Date immediately preceding the Maturity Date, any Redemption Date described in clause (2) of the immediately preceding sentence and any Fundamental Change Repurchase Date described in clause (3) of the immediately preceding sentence shall receive the full interest payment due on the Maturity Date or other applicable Interest Payment Date regardless of whether their Notes have been converted following such Regular Record Date.

(i) The Person in whose name the shares of Common Stock shall be issuable upon conversion shall be treated as a stockholder of record as of the close of business on the relevant Conversion Date. Upon a conversion of Notes, such Person shall no longer be a Holder of such Notes surrendered for conversion.

(j) The Company shall not issue any fractional share of Common Stock upon conversion of the Notes and shall instead pay cash in lieu of delivering any fractional share of Common Stock issuable upon conversion based on the Last Reported Sale Price of the Common Stock on the relevant Conversion Date.

Section 14.03. Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental Changes. (a) If a Make-Whole Fundamental Change occurs or becomes effective prior to the Maturity Date and a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change, the Company shall, under the circumstances described below, increase the Conversion Rate for the Notes so surrendered for conversion by a number of Additional Shares, as described in Section 14.04. A conversion of Notes shall be deemed for these purposes to be “in connection with” such Make-Whole Fundamental Change if the relevant Notice of Conversion is received by the Conversion Agent

from, and including, the Effective Date of the Make-Whole Fundamental Change up to, and including, the Business Day immediately prior to the related Fundamental Change Repurchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for the proviso in clause (b) of the definition thereof, the 35th Trading Day immediately following the Effective Date of the Make-Whole Fundamental Change) (such period, the “Make-Whole Fundamental Change Period”).

(b) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change, the Company shall deliver shares of the Common Stock, including the Additional Shares, in accordance with Section 14.02; provided, however, that if, at the effective time of a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Reference Property following such Make-Whole Fundamental Change is composed entirely of cash, for any conversion of Notes following the Effective Date of the Make-Whole Fundamental Change, the Conversion Obligation shall be calculated based solely on the Stock Price for the transaction and shall be deemed to be an amount of cash per $1,000 principal amount of converted Notes equal to the Conversion Rate (including any adjustment for Additional Shares), multiplied by such Stock Price. The Company shall notify the Trustee, the Conversion Agent (if other than the Trustee) and Holders of Notes in writing of the Effective Date of any Make-Whole Fundamental Change no later than five Business Days after such Effective Date.

(c) The number of Additional Shares, if any, by which the Conversion Rate shall be increased shall be determined by reference to the table in Section 14.04(c), based on the Effective Date of the Make-Whole Fundamental Change and the Stock Price.

Section 14.04. Additional Shares Make-Whole Table. (a) The number of Additional Shares, if any, by which the Conversion Rate shall be increased pursuant to a Voluntary Conversion Increase or for a conversion in connection with a Make-Whole Fundamental Change shall be determined by reference to the table below.

(b) The Stock Prices set forth in the column headings of the table below shall be adjusted as of any date on which the Conversion Rate of the Notes is otherwise adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The amounts by which the Conversion Rate shall be increased as set forth in the table below shall be adjusted in the same manner and at the same time as the Conversion Rate as set forth in Section 14.05.

(c) The following table sets forth the amounts, if any, by which the Conversion Rate shall be increased per $1,000 principal amount of Notes pursuant to this Section 14.04 for each Stock Price and Effective Date set forth below:


	Stock Price
Effective Date	$6.68		$7.00		$8.50		$10.00		$12.50		$15.00		$20.00		$25.00		$30.00		$35.00		$40.00
August 5, 2016		24.9500		23.2329		17.2200		13.3210		9.2184		6.6727		3.7210		2.1060		1.1297		0.5080		0.1223
August 1, 2017		24.9500		22.4857		16.2376		12.3470		8.4128		6.0520		3.3720		1.9156		1.0317		0.4669		0.1153
August 1, 2018		24.9500		21.5900		14.8812		10.9660		7.2648		5.1727		2.8835		1.6516		0.8967		0.4086		0.1018
August 1, 2019		24.9500		20.5043		12.8988		8.9140		5.5928		3.9193		2.2005		1.2828		0.7080		0.3260		0.0813
August 1, 2020		24.9500		19.0714		9.5988		5.6290		3.1584		2.1893		1.2695		0.7668		0.4397		0.2149		0.0628
August 1, 2021		24.9500		18.1071		0.0000		0.0000		0.0000		0.0000		0.0000		0.0000		0.0000		0.0000		0.0000

The exact Stock Prices and Effective Dates may not be set forth in the table above, in which case:

(i) if the Stock Price is between two Stock Prices in the table above or the Effective Date is between two Effective Dates in the table, the amount by which the Conversion Rate will be increased shall be determined by a straight-line interpolation between the amount of Conversion Rate increase set forth for the higher and lower Stock Prices and the earlier and later Effective Dates based on a 365-day year;

(ii) if the Stock Price is greater than $40.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant to subsection (b) above), the Conversion Rate shall not be increased; and

(iii) if the Stock Price is less than $6.68 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant to subsection (b) above), the Conversion Rate for a conversion of Notes in connection with a Make-Whole Fundamental Change shall not be increased but will be increased by 24.9500 (subject to adjustment in the same manner and at the same time as the Conversion Rate as set forth in Section 14.05) with respect to a Voluntary Conversion Increase.

Notwithstanding the foregoing, in no event shall the Conversion Rate per $1,000 principal amount of Notes exceed 149.7005 shares of Common Stock, subject to adjustment in the same manner as the Conversion Rate pursuant to Section 14.05. For the avoidance of doubt, (i) with respect to a conversion in connection with a Make-Whole Fundamental Change, if a Holder converts any or all of its Notes prior to an Effective Date, then, whether or not the Make-Whole Fundamental Change occurs, such Holder will not be entitled to an increased Conversion Rate for such converted Notes in connection with such transaction unless otherwise provided as a result of a Voluntary Conversion Increase; and (ii) under no circumstances shall a Holder receive an increase in the Conversion Rate for both a Voluntary Conversion Increase and a conversion in connection with a Make-Whole Fundamental Change.

(d) Nothing in this Section 14.04 shall prevent an adjustment to the Conversion Rate pursuant to Section 14.05 in respect of a Make-Whole Fundamental Change or a Voluntary Conversion Increase.

Section 14.05. Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company if any of the following events occurs, except that the Company shall not make any adjustments to the Conversion Rate if Holders of the Notes

participate (other than in the case of (x) a share split or share combination or (y) a tender or exchange offer, in each case, that would result in an adjustment to the Conversion Rate pursuant to Section 14.05(a) or Section 14.05(e) below), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Notes, in any of the transactions described in this Section 14.05, without having to convert their Notes, as if they held a number of shares of Common Stock equal to the Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder.

(a) If the Company exclusively issues shares of Common Stock as a dividend or distribution on shares of the Common Stock, or if the Company effects a share split or share combination, the Conversion Rate shall be adjusted based on the following formula:

where,


CR₀	=	the Conversion Rate in effect immediately prior to the close of business on the Record Date of such dividend or distribution, or immediately prior to the open of business on the Effective Date of such share split or share combination, as applicable;

CR'	=	the Conversion Rate in effect immediately after the close of business on such Record Date or immediately after the open of business on such Effective Date, as applicable;

OS₀	=	the number of shares of Common Stock outstanding immediately prior to the close of business on such Record Date or immediately prior to the open of business on such Effective Date, as applicable; and

OS'	=	the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination.

Any adjustment made under this Section 14.05(a) shall become effective immediately after the close of business on the Record Date for such dividend or distribution, or immediately after the open of business on the Effective Date for such share split or share combination, as applicable. If any dividend or distribution of the type described in this Section 14.05(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(b) If the Company issues to all or substantially all holders of the Common Stock any rights, options or warrants entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of the Common Stock at a price per share that is less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, the Conversion Rate shall be increased based on the following formula:

where,


CR₀	=	the Conversion Rate in effect immediately prior to the close of business on the Record Date for such issuance;

CR'	=	the Conversion Rate in effect immediately after the close of business on such Record Date;

OS₀	=	the number of shares of Common Stock outstanding immediately prior to the close of business on such Record Date;

X	=	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and

Y	=	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants, divided by the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the issuance of such rights, options or warrants.

Any increase made under this Section 14.05(b) shall be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the close of business on the Record Date for such issuance. To the extent that such rights, options or warrants are not exercised prior to their expiration or shares of the Common Stock are not delivered after the expiration of such rights, options or warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so issued or if no such right, option or warrant is exercised prior to its expiration, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such Record Date for such issuance had not occurred.

For purposes of this Section 14.05(b), in determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of the Common Stock at a price per share that is less than such average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement for such issuance, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors.

(c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of the Company or rights, options or warrants to acquire shares of its Capital Stock or other securities, to all or substantially all holders of the Common Stock, excluding (i) dividends, distributions or issuances as to which an adjustment was effected pursuant to Section 14.05(a) or Section 14.05(b), (ii) dividends or distributions paid exclusively in cash as to which an adjustment was effected pursuant to Section 14.05(d), (iii) any dividends or distributions of Reference Property in exchange for the Common Stock in connection with any Specified Corporate Event pursuant to Section 14.08 and (iv) Spin-Offs as to which the provisions set forth below in this Section 14.05(c) shall apply (any of such shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire shares of Capital Stock or other securities, the “Distributed Property”), then the Conversion Rate shall be increased based on the following formula:

where,


CR₀	=	the Conversion Rate in effect immediately prior to the close of business on the Record Date for such distribution;

CR'	=	the Conversion Rate in effect immediately after the close of business on such Record Date;

SP₀	=	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and

FMV	=	the fair market value (as determined by the Board of Directors) of the Distributed Property with respect to each outstanding share of the Common Stock on the Record Date for such distribution.

Any increase made under the portion of this Section 14.05(c) above shall become effective immediately after the close of business on the Record Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such distribution had not been declared.

Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP₀” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common Stock receive the Distributed Property, the amount and kind of Distributed Property such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Record Date for the distribution.

If the Board of Directors determines the “FMV” (as defined above) of any distribution for purposes of this Section 14.05(c) by reference to the actual or when-issued trading market for any securities, it shall in doing so consider the prices in such market over the same period used in computing the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution.

With respect to an adjustment pursuant to this Section 14.05(c) where there has been a payment of a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company, that are, or, when issued, will be, listed or admitted for trading on a U.S. national securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula:

where,



CR₀	=	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such Spin-Off;

CR'	=	the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such Spin-Off;

FMV₀	=	the average of the Last Reported Sale Prices of the shares of Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common Stock (determined by reference to the definition of Last Reported Sale Price as set forth in Section 1.01 as if references therein to Common Stock were to such Capital Stock or similar equity interest) over the first 10 consecutive Trading Day period after, and including, the Ex-Dividend Date of the Spin-Off (the “Valuation Period”); and

MP₀	=	the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period.

The increase to the Conversion Rate under the preceding paragraph shall be determined on the last Trading Day of the Valuation Period, but shall be given effect at the open of business on the Ex-Dividend Date for such Spin-Off. Notwithstanding the foregoing, in respect of any conversion of Notes during the Valuation Period, references in the portion of this Section 14.05(c) related to Spin-Offs with respect to 10 consecutive Trading Days shall be deemed to be replaced with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date of such Spin-Off to, but excluding, the Conversion Date in determining the Conversion Rate. If such Spin-Off does not occur, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such distribution had not been declared, effective as of the date on which the Board of Directors determines not to consummate such Spin-Off.

For purposes of this Section 14.05(c) (and subject in all respect to Section 14.12), rights, options or warrants distributed by the Company to all holders of the Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares of the Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of the Common Stock, shall be deemed not to have been distributed for purposes of this Section 14.05(c) (and no adjustment to the Conversion Rate under this Section 14.05(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 14.05(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of the Indenture, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date or Record Date, as applicable, with respect to new rights, options or warrants with such rights (in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the immediately preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 14.05(c) was made, (1) in the case of any such rights, options or warrants that shall all have been redeemed or purchased without exercise by any holders thereof, upon such final redemption or purchase (x) the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Conversion Rate shall then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by a holder or holders of Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights, options or warrants that shall have expired or been terminated (or deemed to have expired or been terminated pursuant to the immediately preceding sentence) without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights, options and warrants had not been issued (to the extent any adjustment to the Conversion Rate was made in connection with such issuance).

For purposes of Section 14.05(a), Section 14.05(b) and this Section 14.05(c), if any dividend or distribution to which this Section 14.05(c) is applicable also includes one or both of:

(A) a dividend or distribution of shares of Common Stock to which Section 14.05(a) is applicable (the “Clause A Distribution”); or

(B) a dividend or distribution of rights, options or warrants to which Section 14.05(b) is applicable (the “Clause B Distribution”),

then, in either case, (1) such dividend or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 14.05(c) is applicable (the “Clause C Distribution”) and any Conversion Rate adjustment required by this Section 14.05(c) with respect to such Clause C Distribution shall then be made, and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Conversion Rate adjustment required by Section 14.05(a) and Section 14.05(b) with respect thereto shall then be made, except that, if determined by the Company (I) the “Record Date” of the Clause A Distribution and the Clause B Distribution shall be deemed to be the Record Date of the Clause C Distribution and (II) any shares of Common Stock included in the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to the close of business on such Record Date or immediately prior to the open of business on such Effective Date, as applicable” within the meaning of Section 14.05(a) or “outstanding immediately prior to the close of business on such Record Date” within the meaning of Section 14.05(b).

(d) If the Company makes any cash dividend or distribution to all or substantially all holders of the Common Stock, the Conversion Rate shall be adjusted based on the following formula:

where,


CR₀	=	the Conversion Rate in effect immediately prior to the close of business on the Record Date for such dividend or distribution;

CR'	=	the Conversion Rate in effect immediately after the close of business on the Record Date for such dividend or distribution;

SP₀	=	the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and

C	=	the amount in cash per share the Company distributes to all or substantially all holders of the Common Stock.

Any increase pursuant to this Section 14.05(d) shall become effective immediately after the close of business on the Record Date for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors determines not to make or pay such dividend or distribution, to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP₀” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms as holders of shares of the Common Stock, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate on the Record Date for such cash dividend or distribution.

(e) If the Company or any of its Subsidiaries make a payment in respect of a tender or exchange offer for the Common Stock, other than an odd lot tender offer, to the extent that the cash and value of any other consideration included in the payment per share of the Common Stock exceeds the Last Reported Sale Price of the Common Stock 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 Conversion Rate shall be increased based on the following formula:

where,


CR₀	=	the Conversion Rate in effect immediately prior to the open of business on the Trading Day next succeeding the date such tender or exchange offer expires;

CR'	=	the Conversion Rate in effect immediately after the open of business on the Trading Day next succeeding the date such tender or exchange offer expires;

AC	=	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares of Common Stock purchased in such tender or exchange offer;

OS₀	=	the number of shares of Common Stock outstanding immediately prior to the time such tender or exchange offer expires (prior to giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer);

OS'	=	the number of shares of Common Stock outstanding immediately after the time such tender or exchange offer expires (after giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer); and

SP'	=	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or exchange offer expires.

The increase to the Conversion Rate under this Section 14.05(e) shall be determined at the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires, but shall be given effect at the open of business on the Trading Day next succeeding the date such tender or exchange offer expires. Notwithstanding the foregoing, in respect of any conversion of Notes within the 10 Trading Days immediately following, and including, the Trading Day next succeeding the expiration date of any tender or exchange offer, references in this Section 14.05(e) with respect to 10 consecutive Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the date that such tender or exchange offer expires and the Conversion Date in determining the Conversion Rate.

If the Company or one of its Subsidiaries is obligated to purchase shares of the Common Stock pursuant to any such tender or exchange offer described in this Section 14.05(e) but is permanently prevented by applicable law from effecting all or any such purchase or all or any portion of such purchases are rescinded, the applicable Conversion Rate shall be readjusted to be the Conversion Rate that would then be in effect if such tender or exchange offer had not been made or had been made only in respect of the purchases that have been effected.

(f) Notwithstanding this Section 14.05 or any other provision of the Indenture or the Notes, if a Conversion Rate adjustment becomes effective as described in clauses (a), (b), (c), (d) and (e) of this Section 14.05, and a Holder that has converted its Notes on or after the relevant Ex-Dividend Date and on or prior to the related Record Date would be treated as the record holder of the shares of Common Stock as of the related Conversion Date as described under Section 14.02(i) based on an adjusted Conversion Rate for such Ex-Dividend Date, then, notwithstanding the Conversion Rate adjustment provisions in this Section 14.05, the Conversion Rate adjustment relating to such Ex-Dividend Date shall not be made for such converting Holder. Instead, such Holder shall be treated as if such Holder were the record owner of the shares of Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment.

(g) Except as stated herein, the Company shall not adjust the Conversion Rate for the issuance of shares of the Common Stock or any securities convertible into or exchangeable for shares of the Common Stock or the right to purchase shares of the Common Stock or such convertible or exchangeable securities.

(h) In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this Section 14.05, and to the extent permitted by applicable law and subject to the applicable rules of any exchange on which any of the Company’s securities are then listed, the Company from time to time may increase the Conversion Rate by any amount for a period of at least 20 Business Days if the Board of Directors determines that such increase would be in the Company’s best interest. In addition, to the extent permitted by applicable law and subject to the applicable rules of any exchange on which any of the Company’s securities are then listed, the Company may (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock in connection with a dividend or distribution of shares of Common Stock (or rights to acquire shares of Common Stock) or similar event. Whenever the Conversion Rate is increased pursuant to either of the preceding two sentences, the Company shall mail to the Holder of each Note at its last address appearing on the Security Register a notice of the increase at least 15 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.

(i) Notwithstanding anything to the contrary in this Article 14, the Conversion Rate shall not be adjusted:

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

(ii) upon the issuance of any shares of Common Stock or options or rights to purchase 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 shares of the Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in clause (ii) of this subsection;

(iv) upon the repurchase of any shares of the Common Stock pursuant to an open-market share repurchase program or other buy-back transaction that is not a tender offer or exchange offer of the kind described in Section 14.05(e);

(v) solely for a change in the par value (or lack of par value) of the Common Stock; or

(vi) for accrued and unpaid interest, if any.

(j) 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 (1/10,000th) of a share. The Company shall not adjust the Conversion Rate pursuant to clauses (a) through (e) of this Section 14.05 unless the adjustment would result in a change of at least 1% in the then effective Conversion Rate. However, the Company shall carry forward any adjustment to the Conversion Rate that the Company would otherwise have to make and take that adjustment into account in any subsequent adjustment. Notwithstanding the foregoing, all such carried-forward adjustments shall be made (i) in connection with any subsequent adjustment to the Conversion Rate of at least 1% and (ii) on the Conversion Date for any Notes.

(k) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee (and the Conversion Agent if not the Trustee) an Officer’s 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 Officer’s 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 Officer’s 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 deliver such notice of such adjustment of the Conversion Rate to each Holder at its last address appearing on the Security Register of this Supplemental Indenture, within 20 calendar days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

(l) For purposes of this Section 14.05, the number of shares of Common Stock at any time outstanding shall not include shares of Common Stock held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include shares of Common Stock issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock.

(m) If the application of Conversion Rate adjustments pursuant to clauses (a), (b), (c), (d) and (e) of this Section 14.05 would result in a decrease in the Conversion Rate, no adjustment to the Conversion Rate will be made (other than as a result of a reverse share split or share combination or the reversal of an increase to the Conversion Rate where the relevant event did not occur, as specified in this Supplemental Indenture).

(n) The Trustee and any Conversion Agent shall not at any time be under any duty or responsibility to any Holder to determine whether any facts exist which may require any adjustment of the Conversion Rate, or with respect to the nature or extent of any such adjustment when made, or with respect to the method employed, in this Supplemental Indenture or in any supplemental indenture provided to be employed, in making the same, or whether a supplemental indenture need be entered into. Neither the Trustee nor any Conversion Agent shall be accountable with respect to the validity or value (or the kind or amount) of any Common Stock which may at any time be delivered upon the conversion of any Notes; and it or they do not make any representation with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to deliver any shares of Common Stock and cash payment in lieu of a fractional share upon the surrender of any Note for the purpose of conversion; and the Trustee and any Conversion Agent shall not be responsible for any failure of the Company to comply with any of the Company’s covenants related to such conversion.

Section 14.06. Adjustments of Prices. Whenever any provision of the Indenture requires the Company to calculate the Last Reported Sale Prices and, if applicable, the period for determining the Stock Price for purposes of a Make-Whole Fundamental Change, the Board of Directors shall make appropriate adjustments (to the extent that no corresponding adjustment is otherwise made pursuant to clauses (a), (b), (c), (d) and (e) of Section 14.05) to each to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Effective Date, Ex-Dividend Date, expiration date or Record Date, as the case may be, of the event occurs, at any time during the period when the Last Reported Sale Prices or Stock Prices are to be calculated.

Section 14.07. 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 shares of Common Stock to provide for conversion of the Notes from time to time as such Notes are presented for conversion (assuming that at the time of computation of such number of shares, all such Notes would be converted by a single Holder).

Section 14.08. Effect of Recapitalizations, Reclassifications and Changes of the Common Stock.

(a) In the case of:

(i) any recapitalization, reclassification or change of the Common Stock (other than changes resulting from a subdivision or combination),

(ii) any consolidation, merger or combination involving the Company,

(iii) any sale, lease or other transfer to a third party of the consolidated assets of the Company and the Company’s Subsidiaries substantially as an entirety or

(iv) any statutory share exchange,

in each case, as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination thereof) (any such event, a “Specified Corporate Event”), then the Company or the successor or acquiring corporation, as the case may be, shall execute with the Trustee a supplemental indenture permitted under Section 10.02(l) providing that, at and after the effective time of such Specified Corporate Event, the right to convert each $1,000 principal amount of Notes shall be changed into a right to convert such principal amount of Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such Specified Corporate Event would have owned or been entitled to receive (the “Reference Property,” with each “unit of Reference Property” meaning the kind and amount of Reference Property that a holder of one share of Common Stock is entitled to receive) upon the occurrence of such Specified Corporate Event and the Company or the successor or acquiring corporation, as the case may be, shall execute with the Trustee a supplemental indenture providing for such change in the right to convert each $1,000 principal amount of Notes.

If the Specified Corporate Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of shareholder election), then (i) the Reference Property into which the Notes will be convertible shall be deemed to be (x) the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election or (y) if no holders of Common Stock affirmatively make such an election, the types and amounts of consideration actually received by the holders of Common Stock, and (ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common Stock. If the holders of the Common Stock receive only cash in such Specified Corporate Event, then for all conversions for which the relevant Conversion Date occurs after the effective date of such Specified Corporate Event (A) the consideration due upon conversion of each $1,000 principal amount of Notes shall be solely cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased by any Additional Shares pursuant to Sections 14.01(b), 14.03 and 14.04), multiplied by the price paid per share of Common Stock in such Specified Corporate Event and (B) the Company shall satisfy the Conversion Obligation by paying such cash amount to converting Holders on the third Business Day immediately following the relevant Conversion Date. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) in writing of such weighted average as soon as practicable after such determination is made.

Such supplemental indenture described in the second immediately preceding paragraph shall provide for (x) anti-dilution adjustments that shall be as nearly equivalent as practicable to the adjustments provided for in this Article 14, with respect to any Reference Property consisting of shares of Common Equity, and (y) with respect to any other Reference Property (other than cash), such adjustments (if any) that the Board of Directors determines in good faith are appropriate. If, in the case of any Specified Corporate Event, the Reference Property includes shares of stock, securities or other property or assets of a Person other than the Company or the successor or purchasing corporation, as the case may be, in such Specified Corporate Event, such other Person will also execute such supplemental indenture, and such supplemental indenture will contain such additional provisions to protect the interests of the Holders, including the right of holders to require the Company to purchase their Notes upon a Fundamental Change as set forth in Article 15, as the Board of Directors reasonably consider necessary by reason of the foregoing. If the notes become convertible into Reference Property, the Company shall notify in writing the Holders, the Trustee and the Conversion Agent (if other than the Trustee).

(b) When the Company executes a supplemental indenture pursuant to subsection (a) of this Section 14.08, the Company shall promptly file with the Trustee an Officer’s Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or property or asset that will comprise a unit of Reference Property after any such Specified Corporate 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 Holders. The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder, at its address appearing on the Security Register provided for in the Indenture, within 20 calendar days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

(c) The Company shall not become a party to any Specified Corporate Event unless its terms are consistent with this Section 14.08. None of the foregoing provisions shall affect the right of a holder of Notes to convert its Notes into shares of Common Stock, all as set forth in Section 14.01 and Section 14.02, prior to the effective date of such Specified Corporate Event.

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

Section 14.09. Certain Covenants. (a) The Company covenants that all shares of Common Stock issued upon conversion of Notes will be fully paid and non-assessable by the Company and free from all taxes, liens, charges and preemptive rights with respect to the issue thereof.

(b) The Company covenants that, if any shares of Common Stock 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 before such shares of Common Stock 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.

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

Section 14.10. Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any Holder 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 shares of Common Stock, 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 shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article. Neither the Trustee nor any other Conversion Agent shall have any duty or responsibility whatsoever to determine whether the Company has a Conversion Obligation or compliance with the conversion procedures, or to make or confirm any calculations with respect to the settlement provisions of Sections 14.02 through 14.08. 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 14.08 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Notes after any event referred to in such Section 14.08 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.02 of the Base Indenture, may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officer’s Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. Neither the Trustee nor the Conversion Agent shall be responsible for determining whether any event contemplated by this Article 14 has occurred that makes the Notes eligible for conversion or no longer eligible therefor until the Company has delivered to the Trustee and the Conversion Agent the notices referred to in this Article 14 with respect to the commencement or termination of such conversion rights, on which notices the Trustee and the Conversion Agent may conclusively rely, and the Company agrees to deliver such notices to the Trustee and the Conversion Agent immediately after the occurrence of any such event or at such other times as shall be provided for in this Article 14. The rights, benefits and privileges of the Trustee set forth in the Base Indenture shall be applicable to the Conversion Agent, and the provisions set forth in Section 7.01 of the Base Indenture relating to the Trustee shall apply to the Conversion Agent.

Section 14.11. Notice to Holders Prior to Certain Actions. In case of any:

(a) action by the Company that would require an adjustment in the Conversion Rate pursuant to Section 14.05 or Section 14.12;

(b) Specified Corporate Event; or

then, in each case (unless notice of such event is otherwise required pursuant to another provision of the Indenture) and to the extent applicable, the Company shall cause to be filed with the Trustee and the Conversion Agent (if other than the Trustee) and to be sent to each Holder at its address appearing on the Security Register, a notice stating the date on which a record is to be taken for the purpose of such action by the Company or, if a record is not to be taken, the date as of which the holders of Common Stock of record are to be determined for the purposes of such action by the Company no later than the earlier of the date notice of such date is required to be provided under Rule 10b-17 of the Exchange Act or applicable rules of the Relevant Stock Exchange and such date is publicly announced by the Company. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such action by the Company, Specified Corporate Event, dissolution, liquidation or winding-up.

Section 14.12. Shareholder Rights Plans. If the Company has a shareholder rights plan in effect upon conversion of the Notes, each share of Common Stock, if any, issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such conversion shall bear such legends, if any, in each case as may be provided by the terms of any such shareholder rights plan, as the same may be amended from time to time. However, if, prior to any conversion of Notes, the rights have separated from the shares of Common Stock in accordance with the provisions of the applicable shareholder rights plan, the Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all or substantially all holders of the Common Stock Distributed Property as provided in Section 14.05(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. Intentionally Omitted.

Section 15.02. Repurchase at Option of Holders Upon a Fundamental Change. (a) If a Fundamental Change occurs or becomes effective at any time prior to the Maturity Date, each Holder 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 equal to $1,000 or an integral multiple of $1,000, on the date (the “Fundamental Change Repurchase Date”), subject to postponement to comply with any applicable law, specified by the Company that is not less than 20 calendar days or more than 35 Business Days following the date of the Fundamental Change Company Notice at a repurchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”), unless the Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to the Interest Payment Date to which such Regular Record Date relates, in which case the Company shall instead pay the full amount of

accrued and unpaid interest to Holders of record as of such Regular Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of Notes to be repurchased pursuant to this Article 15.

(b) Repurchases of Notes under this Section 15.02 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 in Attachment 2 to the Form of Note attached hereto as Exhibit A, if the Notes are Physical Notes, or in compliance with the Depositary’s procedures for surrendering interests in Global Notes, if the Notes are Global Notes, in each case prior to the close of business on the second Business Day immediately preceding the Fundamental Change Repurchase Date; and

(ii) delivery of the Notes, if the Notes are Physical Notes, to the Paying Agent at any time after delivery of the Fundamental Change Repurchase Notice (together with all necessary endorsements for transfer) at the Corporate Trust Office of the Paying Agent, or book-entry transfer of the Notes, if the Notes are Global Notes, in compliance with the procedures of the Depositary, in each case such delivery being a condition to receipt by the Holder of the Fundamental Change Repurchase Price therefor.

The Fundamental Change Repurchase Notice in respect of any Notes to be repurchased shall state:

(i) in the case of Physical Notes, the certificate numbers of the Notes to be delivered for repurchase, which portion must be $1,000 or an integral multiple thereof;

(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 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 Global Notes, the Fundamental Change Repurchase Notice must comply with appropriate Depositary procedures.

Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change Repurchase Notice contemplated by this Section 15.02 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 second 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 15.03.

The Paying Agent (if other than the Company) shall promptly notify the Company and the Trustee (if other than the Paying Agent) of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal thereof.

(c) On or before the 20th calendar day after the occurrence of the effective date of a Fundamental Change, the Company shall provide to all Holders of Notes and the Trustee and the Paying Agent (in the case of a Paying Agent other than the Trustee) a written notice (the “Fundamental Change Company Notice”) of the occurrence of the Fundamental Change and of the repurchase right at the option of the Holders arising as a result thereof. In the case of Physical Notes, such notice shall be by first class mail or, in the case of Global Notes, such notice shall be delivered in accordance with the applicable procedures of the Depositary. Each Fundamental Change Company Notice shall specify:

(i) the events causing the Fundamental Change;

(ii) the effective date of the Fundamental Change;

(iii) the last date on which a Holder may exercise the repurchase right pursuant to this Article 15;

(iv) the Fundamental Change Repurchase Price;

(v) the Fundamental Change Repurchase Date;

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

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

(viii) that the Notes with respect to which a Fundamental Change Repurchase Notice has been delivered by a Holder may be converted only if the Holder withdraws the Fundamental Change Repurchase Notice in accordance with the terms of the Indenture; and

(ix) 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 Holders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section 15.02.

At the Company’s written request, the Trustee shall give such notice in the Company’s name and at the Company’s expense; provided, however, that, in all cases, the text of such Fundamental Change Company Notice shall be prepared by the Company.

(d) Notwithstanding the foregoing, no Notes may be repurchased by the Company on any date 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 such 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). The Paying

Agent will promptly return to the respective Holders thereof any Physical Notes held by it during the acceleration of the Notes (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), or any instructions for book-entry transfer of the Notes in compliance with the procedures of the Depositary shall be deemed to have been cancelled, and, upon such return or cancellation, as the case may be, the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn.

(e) Notwithstanding the foregoing, the Company shall not be required to purchase, or to make an offer to purchase, any Notes upon a Fundamental Change if a third party makes such an offer in the same manner, at the same time and otherwise in compliance with the requirements for an offer made by the Company as set forth in this Article 15 and such third party purchases all Notes properly surrendered and not validly withdrawn under its offer in the same manner, at the same time and otherwise in compliance with the requirements for an offer made by the Company as set forth in this Article 15.

(f) To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Article 15, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under such provisions of this Article 15 by virtue of such conflict; provided that the Company shall have complied with Section 15.05.

Section 15.03. Withdrawal of Fundamental Change Repurchase Notice. A Fundamental Change Repurchase Notice may be withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the Corporate Trust Office of the Paying Agent, the Trustee and the Conversion Agent (if other than the Trustee) in accordance with this Section 15.03 at any time prior to the close of business on the second Business Day immediately preceding the Fundamental Change Repurchase Date, specifying:

(i) the principal amount of the Notes with respect to which such notice of withdrawal is being submitted,

(ii) if Physical Notes have been issued, the certificate number of the Note in respect of 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 Global Notes, the notice must comply with appropriate procedures of the Depositary.

Section 15.04. 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 4.03 of the Base Indenture) on or prior to 11:00 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 close of business on the second Business Day immediately preceding the Fundamental Change Repurchase Date) will be made on the later of (i) the Fundamental Change Repurchase Date (provided the Holder has satisfied the conditions in Section 15.02) 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 15.02 by mailing checks for the amount payable to the Holders of such Notes entitled thereto as they shall appear in the Security 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.

(b) If by 11:00 a.m. New York City time, on the Fundamental Change Repurchase Date, the Trustee (or other Paying Agent appointed by the Company, or if the Company is acting as its own Paying Agent, sets aside, segregates and holds in trust as provided in Section 4.03) holds money sufficient to make payment on all the Notes or portions thereof that are to be repurchased on such Fundamental Change Repurchase Date, then, with respect to the Notes that have been properly surrendered for repurchase and have not been validly withdrawn, (i) such Notes will cease to be Outstanding, (ii) interest will cease to accrue on such 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) and (iii) all other rights of the Holders of such Notes will terminate (other than the right to receive the Fundamental Change Repurchase Price and, if the Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to the related Interest Payment Date, the right of the Holder of record on such Regular Record Date to receive the related interest payment).

(c) Upon surrender of a Note that is to be repurchased in part pursuant to Section 15.02, 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 15.05. Covenant to Comply with Applicable Laws Upon Repurchase of Notes. In connection with any repurchase offer, the Company will, if required:

(a) comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act;

(b) file a Schedule TO or any other required schedule under the Exchange Act; and

(c) otherwise comply with all federal and state securities laws in connection with any offer by the Company to repurchase the Notes;

in each case, so as to permit the rights and obligations under this Article 15 to be exercised in the time and in the manner specified in this Article 15.

ARTICLE 16

OPTIONAL REDEMPTION

Section 16.01. Applicability of Article 3 of the Base Indenture. Article 3 of the Base Indenture shall not apply to the Notes. Instead the provisions set forth in this Article 16 shall, with respect to the Notes, supersede in its entirety Article 3 of the Base Indenture, and all references in the Base Indenture to Article 3 thereof and the provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to this Article 16 or the applicable provisions set forth in this Article 16, respectively.

Section 16.02. Optional Redemption. No sinking fund is provided for the Notes. The Company may redeem (an “Optional Redemption”) for cash all or any portion of the Notes, at the Redemption Price, if the Last Reported Sale Price of the Common Stock is equal to or greater than 200% of the Conversion Price then in effect for at least 20 Trading Days (whether or not consecutive) during any 30 consecutive Trading Day period (including the last Trading Day of such period) ending within the five Trading Days immediately preceding the date on which the Company provides the Redemption Notice in accordance with Section 16.03.

Section 16.03. Notice of Optional Redemption; Selection of Notes. (a) In case the Company exercises its Optional Redemption right to redeem all or, as the case may be, any portion of the Notes pursuant to Section 16.02, it shall fix a date for redemption (each, a “Redemption Date”) and it shall deliver a notice of such Optional Redemption (a “Redemption Notice”) not less than 30 calendar days nor more than 60 calendar days prior to the Redemption Date to the Trustee, the Conversion Agent (if other than the Trustee), the Paying Agent (if other than the Trustee) and each Holder of Notes. The Redemption Date must be a Business Day.

(b) The Redemption Notice, if given in the manner herein provided, shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. In any case, failure to give such Redemption Notice or any defect in the Redemption Notice to the Holder of any Note designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Note.

(i) the Redemption Date;

(ii) the Redemption Price;

(iii) that on the Redemption Date, the Redemption Price will become due and payable upon each Note to be redeemed, and that interest thereon, if any, shall cease to accrue on and after the Redemption Date;

(iv) the place or places where such Notes are to be surrendered for payment of the Redemption Price;

(v) that Holders may surrender their Notes for conversion at any time prior to the close of business on the Business Day immediately preceding the Redemption Date;

(vi) the Conversion Rate;

(vii) the CUSIP, ISIN or other similar numbers, if any, assigned to such Notes; and

(viii) in case any Note is to be redeemed in part only, the portion of the principal amount thereof to be redeemed and on and after the Redemption Date, upon surrender of such Note, a new Note in principal amount equal to the unredeemed portion thereof shall be issued.

A Redemption Notice shall be irrevocable.

At the Company’s request, the Trustee shall give the notice of redemption in the name of and at the Company’s expense; provided, however, that the Company has delivered to the Trustee, at least five Business Days prior to the date that the Company requests such notice of redemption to be delivered to the Holders (unless a shorter notice period shall be agreed to by the Trustee), an Officer’s Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph.

(d) If fewer than all of the Outstanding Notes are to be redeemed, the Notes to be redeemed shall be selected: (i) if the Notes are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange on which the Notes are listed; (ii) if the Notes are not so listed but are represented by a Global Note, then by lot or otherwise in accordance with the Depositary’s applicable procedures; or (iii) if the Notes are not so listed and are not represented by a Global Note, then (in principal amounts of $1,000 or multiples thereof) on a pro rata basis, by lot or by such other method as the Trustee in its sole discretion shall deem fair and appropriate (it being understood that as long as Notes are held by DTC, notice will be given by the rules of the Depositary). If any Note selected for partial redemption is submitted for conversion in part after such selection, the portion of the Note submitted for conversion shall be deemed (so far as may be possible) to be the portion selected for redemption.

(e) In the event of any redemption in part, neither the Company nor the Security Register shall be required to register the transfer of or exchange any Note so selected for redemption, in whole or in part, except the unredeemed portion of any Note being redeemed in part.

Section 16.04. Payment of Notes Called for Redemption. (a) If any Redemption Notice has been given in respect of the Notes in accordance with Section 16.03, the Notes shall become due and payable on the Redemption Date at the place or places stated in the Redemption Notice and at the applicable Redemption Price. On presentation and surrender of the Notes at the place or places stated in the Redemption Notice, the Notes shall be paid and redeemed by the Company at the applicable Redemption Price.

(b) Prior to 11:00 a.m. New York City time on the Redemption Date, the Company shall deposit with the Paying Agent or, if the Company or a Subsidiary of the Company is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 4.03(b) of the Base

Indenture an amount of cash (in immediately available funds if deposited on the Redemption Date), sufficient to pay the Redemption Price of all of the Notes to be redeemed on such Redemption Date. Subject to receipt of funds by the Paying Agent, payment for the Notes to be redeemed shall be made on the Redemption Date for such Notes. The Paying Agent shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Redemption Price.

Section 16.05. Restrictions on Redemption. The Company may not redeem any Notes on any date if the principal amount of the Notes has been accelerated in accordance with the terms of the Indenture, 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).

[FORM OF REVERSE OF NOTE]

Inotek Pharmaceuticals Corporation

5.75% Convertible Senior Note due 2021

This Note is one of a duly authorized issue of Notes of the Company, designated as its 5.75% Convertible Senior Notes due 2021 (the “Notes”), limited to the aggregate principal amount of $50,000,000 (as increased by an amount equal to the aggregate principal amount of any additional Notes purchased by the Underwriters pursuant to the exercise of their over-allotment option as set forth in the Underwriting Agreement) all issued or to be issued under and pursuant to an Indenture dated as of August 5, 2016 (the “Base Indenture”), as amended and supplemented by the First Supplemental Indenture dated as of August 5, 2016 (herein called the “Supplemental Indenture”; the Base Indenture, as amended and supplemented by the Supplemental Indenture, and as it may be further amended or supplemented from time to time, the “Indenture”), between the Company and Wilmington Trust, National Association, a national banking association, as trustee (the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Notes. Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture. Capitalized terms used in this Note and not defined in this Note shall have the respective meanings set forth in the Indenture.

In case certain Events of Default shall have occurred and be continuing, the principal of, and interest on, all Notes may be declared, by either the Trustee or Holders of at least 25% in aggregate principal amount of Notes then Outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions and certain exceptions set forth in the Indenture.

Subject to the terms and conditions of the Indenture, the Company will make all payments and deliveries in respect of the Redemption Price on the Redemption Date, the Fundamental Change Repurchase Price on the Fundamental Change Repurchase Date and the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders a Note to a Paying Agent to collect such payments in respect of the Note. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts.

The Indenture contains provisions permitting the Company and the Trustee in certain circumstances, without the consent of the Holders of the Notes, and in certain other circumstances, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time Outstanding, evidenced as in the Indenture provided, to execute supplemental indentures modifying the terms of the Indenture and the Notes as described therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority in aggregate principal amount of the Notes at the time Outstanding may on behalf of the Holders of all of the Notes waive any past Default or Event of Default under the Indenture and its consequences.

A-5

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or deliver, as the case may be, the principal (including the Redemption Price or the Fundamental Change Repurchase Price, if applicable) of, accrued and unpaid interest on, and the consideration due upon conversion of, this Note at the place, at the respective times, at the rate and in the lawful money or shares of Common Stock, as the case may be, herein prescribed.

The Notes are issuable in registered form without coupons in denominations of $1,000 principal amount and integral multiples thereof. At the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, Notes may be exchanged for a like aggregate principal amount of Notes of other authorized denominations, without payment of any service charge but, if required by the Company or Trustee, with payment of a sum sufficient to cover any transfer or similar tax that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such exchange of Notes being different from the name of the Holder of the old Notes surrendered for such exchange.

The Notes shall be redeemable at the Company’s option in accordance with the terms and subject to the conditions specified in the Indenture.

Upon the occurrence of a Fundamental Change prior to the Maturity Date, the Holder has 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 (in principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change Repurchase Date at a price equal to the Fundamental Change Repurchase Price.

Subject to the provisions of the Indenture, the Holder hereof has the right, at its option, prior to the close of business on the second Business Day immediately preceding the Maturity Date, to convert any Notes or portion thereof that is $1,000 or an integral multiple thereof, into shares of Common Stock at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture.
