ARTICLE 2

ISSUE, DESCRIPTION, EXECUTION, REGISTRATION AND EXCHANGE OF NOTES

Section 2.01 Designation and Amount. The Notes shall be designated as the “6.00% Convertible Senior Secured Notes due 2024.” The aggregate principal amount of Notes that may be authenticated and delivered under this Indenture is initially limited to $207,001,000 (the “Initial Issuance Amount”), subject toSection 2.10 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 2.02 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 inExhibit A, the terms and provisions of which shall constitute, and are hereby expressly incorporated in and made a part of this Indenture. To the extent applicable, the Company and the Trustee, by their execution and delivery of this 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 this 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 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 (other than legends restricting transfer) or endorsements as the Officer executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of this Indenture, or as may be required 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 or designated for issuance, or to conform to usage or to indicate any special limitations or restrictions to which any particular Notes are subject.

Each Global Note shall represent such principal amount of the outstanding Notes as shall be specified therein and shall provide that it shall represent the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be increased or reduced to reflect Optional Mandatory Conversions, repurchases, cancellations, conversions, transfers, exchanges or issuances of additional Notes (to the extent such issuances are fungible with the Notes represented by such Global Note for U.S. federal income tax and securities law purposes) permitted hereby. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the amount of outstanding Notes represented thereby shall be made by the Trustee or the Custodian, at the direction of the Trustee, in such manner and upon instructions given by the Holder of such Notes in accordance with this Indenture. Payment of principal (including the Fundamental Change Repurchase Price, if applicable) of, and any accrued and unpaid interest on, a Global Note shall be made to the Holder of such Note on the date of payment, unless a record date or other means of determining Holders eligible to receive payment is provided for herein.

Section 2.03 Date and Denomination of Notes; Interest and Defaulted Amounts. (a) The Notes shall be issuable in registered form without coupons in minimum denominations of $1,000 principal amount and integral multiples of $1,000 in excess thereof. Each Note shall be dated the date of its authentication and shall bear interest from the date specified on the face of such Note. Interest on the Notes shall be computed on the basis of a360-day year composed of twelve30-day months and, for partial months, on the basis of the number of days actually elapsed in a30-day month.

(b) The Person in whose name any Note (or its Predecessor Note) is registered on the Note Register at the close of business on any Interest Record Date with respect to any Interest Payment Date shall be entitled to receive any interest payable on such Interest Payment Date. The principal amount of any Note (x) in the case of any Physical Note, shall be payable to the Holder of those Notes by wire transfer of immediately available funds to that Holder’s account within the United States and (y) in the case of any Global Note, shall be payable by wire transfer of immediately available funds to the account of the Depositary or its nominee in accordance with the Applicable Procedures of the Depositary.

(c) The Company may elect to pay interest on the Notes in cash or, if the Equity Payment Conditions (other than clause (iii) of the definition thereof) are met, in cash or in shares of Common Stock. The Paying Agent will pay principal of, and cash interest on, Global Notes in immediately available funds to the registered holder of such Global Note, initially The Depository Trust Company or its nominee, as the case may be, on each Interest Payment Date, Fundamental Change Repurchase Date or other payment date, as the case may be. The value of a share of Common Stock issued to pay any interest on Physical Notes and Global Notes, if the Company elects to make payment of such interest in shares of Common Stock, will be equal to 95% of the simple average of the Daily VWAP for the 10 Trading Days ending on, and including, the Trading Day immediately preceding the relevant Interest Payment Date (the “Averaging Period”) as set forth in an Officers’ Certificate and delivered to the Trustee and Paying Agent. The Company may only elect to make payment of interest in Common Stock if such Common Stock is not subject to restrictions on transfer under the Securities Act by Persons other than Affiliates of the Company, whether based on an effective registration statement covering such shares or on an applicable exemption from such registration requirement for resale thereof.

(d) The Company shall notify the Holders, the Trustee and the Transfer Agent in writing of whether it will make such interest payment in cash or in shares of Common Stock at least two Trading Days before the start of the applicable Averaging Period. If the Company notifies Holders that it will make an interest payment in shares of Common Stock, and all or a portion of such payment would cause such Holder to exceed its Beneficial Ownership Limitation, such Holder shall notify the Company via email at at least two Trading Days prior to the relevant Interest Payment Date, which notice shall specify the number of shares of Common stock such Holder may receive without exceeding the Beneficial Ownership Limitation with respect to such Holder. If the Company chooses to make such payment in shares of Common Stock, on the applicable Interest Payment Date, the Company shall either (x) if the Transfer Agent is participating in The Depository Trust Company’s Fast Automated Securities Transfer Program, credit the number of shares of Common Stock payable as an interest payment to such Holder’s or its designee’s balance account with the Depositary through its Deposit/Withdrawal at Custodian system, or (y) if the Transfer Agent is not participating in The Depository Trust Company’s Fast Automated Securities Transfer Program, issue and dispatch by overnight courier to each Holder, a certificate, or a statement evidencing the issuance of Common Stock in book-entry format, registered in the Company’s share register in the name of such Holder or its designee for the number of shares of Common Stock to which such Holder is entitled in connection with such payment. The Company shall pay any cash interest (i) on any Physical Notes to the Holder of those Notes by wire transfer of immediately available funds to that Holder’s account within the United States or (ii) on any Global Note by wire transfer of immediately available funds to the account of the Depositary or its nominee. If, after providing notice that it will pay an interest

payment in shares of Common Stock, the Company becomes unable to deliver such shares of Common Stock on the relevant Interest Payment Date, the Company shall pay such interest payment in cash.

(e) 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 then-applicable interest 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 any 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 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 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 days and not less than 10 days prior to the date of the proposed payment, and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Company shall promptly notify the Trustee and the Holders of such special record date of the proposed payment of such Defaulted Amounts and the special record date therefor to be delivered to each Holder not less than 10 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 thisSection 2.03(e).

(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.

Section 2.04 Execution, Authentication and Delivery of Notes. The Notes shall be signed in the name and on behalf of the Company by the manual or facsimile signature of one or more of its Officers.

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Notes executed by the Company to the Trustee for authentication, together

with a Company Order for the authentication and delivery of such Notes and an Officers’ Certificate and an Opinion of Counsel, and the Trustee in accordance with such Company Order shall authenticate and deliver such Notes, without any further action by the Company hereunder.

Only such Notes as shall bear thereon a certificate of authentication substantially in the form set forth on the Form of Note attached asExhibit A hereto, executed manually by an authorized officer of the Trustee (or an authenticating agent appointed by the Trustee as provided bySection 18.10), shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. Such certificate by the Trustee (or such an authenticating agent) upon any Note executed by the 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 this Indenture.

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

Section 2.05 Exchange and Registration of Transfer of Notes; Restrictions on Transfer; Depositary. (a) The Company shall cause to be kept at the Corporate Trust Office a register (the register maintained in such office or in any other office or agency of the Company designated pursuant toSection 4.02, the “Note Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Notes and of transfers of Notes. Such register shall be in written form or in any form capable of being converted into written form within a reasonable period of time. The Trustee is hereby initially appointed the “Note Registrar” for the purpose of registering Notes and transfers of Notes as herein provided. The Company may appoint one or moreco-Note Registrars in accordance withSection 4.02.

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

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

All Notes presented or surrendered for registration of transfer or for exchange, repurchase or conversion shall (if so required by the Company, the Trustee, the Note Registrar or anyco-Note

Registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in form reasonably satisfactory to the Company and duly executed, by the Holder thereof or itsattorney-in-fact duly authorized in writing.

No service charge shall be imposed to a Holder by the Company, the Trustee, the Note Registrar, anyco-Note Registrar or the Paying Agent for any exchange or registration of transfer of Notes, but the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax required in connection therewith as a result of the name of the Holder of the new Notes issued upon such exchange or registration of transfer being different from the name of the Holder of the old Notes surrendered for exchange or registration of transfer.

None of the Company, the Trustee, the Note Registrar or anyco-Note Registrar shall be required to exchange or register a transfer of (i) any Notes surrendered for conversion or, if a portion of any Note is surrendered for conversion, such portion thereof surrendered for conversion, (ii) any Notes, or a portion of any Note, surrendered for repurchase (and not withdrawn) in accordance withArticle 15 or (iii) any Notes selected for Optional Mandatory Conversion in accordance withArticle 16, except the unredeemed portion of any Note being redeemed in part.

All Notes issued upon any registration of transfer or exchange of Notes in accordance with this Indenture shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this 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 fourth paragraph from the end ofSection 2.05(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. 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 this Indenture (including the restrictions on transfer set forth herein) and the Applicable Procedures of the Depositary.

(c) Every Note that bears or is required under thisSection 2.05(c) to bear the legend set forth in thisSection 2.05(c) (together with any Common Stock issued upon conversion of the Notes that is required to bear the legend set forth inSection 2.05(d), collectively, the “Restricted Securities”) shall be subject to the restrictions on transfer set forth in thisSection 2.05(c) (including the legend set forth below), unless such restrictions on transfer shall be eliminated or otherwise waived by written consent of the Company, and the Holder of each such Restricted Security, by such Holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. As used in thisSection 2.05(c) andSection 2.05(d), the term “transfer” encompasses any sale, pledge, transfer or other disposition whatsoever of any Restricted Security.

Until the date (the “Resale Restriction Termination Date”) that is the later of (1) the date that is one year after the last date of original issuance of the Notes, or such shorter period of time as permitted by Rule 144 or any successor provision thereto, and (2) such later date, if any, as may be required by applicable law, any certificate evidencing such Note (and all securities issued in exchange therefor or substitution thereof, other than Common Stock, if any, issued upon

conversion thereof, which shall bear the legend set forth inSection 2.05(d), if applicable) shall bear a legend in substantially the following form (unless such Notes have been sold pursuant to an effective registration statement under the Securities Act that continues to be effective at the time of such transfer, or sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, or unless otherwise agreed by the Company in writing, with notice thereof to the Trustee):

THIS SECURITY AND THE COMMON STOCK, IF ANY, ISSUABLE UPON CONVERSION OF THIS SECURITY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER:

(1) REPRESENTS THAT IT AND ANY ACCOUNT FOR WHICH IT IS ACTING IS A “QUALIFIED INSTITUTIONAL BUYER” (WITHIN THE MEANING OF RULE 144A UNDER THE SECURITIES ACT) AND THAT IT EXERCISES SOLE INVESTMENT DISCRETION WITH RESPECT TO EACH SUCH ACCOUNT, AND

(2) AGREES FOR THE BENEFIT OF ACORDA THERAPEUTICS, INC. (THE “COMPANY”) THAT IT WILL NOT OFFER, SELL, PLEDGE OR OTHERWISE TRANSFER THIS SECURITY OR ANY BENEFICIAL INTEREST HEREIN PRIOR TO THE DATE THAT IS THE LATER OF (X) ONE YEAR AFTER THE LAST ORIGINAL ISSUE DATE HEREOF OR SUCH SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER THE SECURITIES ACT OR ANY SUCCESSOR PROVISION THERETO AND (Y) SUCH LATER DATE, IF ANY, AS MAY BE REQUIRED BY APPLICABLE LAW, EXCEPT:

(A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, OR

(B) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT, OR

(D) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

PRIOR TO THE REGISTRATION OF ANY TRANSFER IN ACCORDANCE WITH CLAUSE (2)(D) ABOVE, THE COMPANY AND THE TRUSTEE RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO DETERMINE THAT THE PROPOSED TRANSFER IS BEING MADE IN COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

No transfer of any Note prior to the Resale Restriction Termination Date will be registered by the Note Registrar unless the applicable box on the Form of Assignment and Transfer has been checked.

Any Note (or security issued in exchange or substitution therefor) (i) as to which such restrictions on transfer shall have expired in accordance with their terms, (ii) that has been transferred pursuant to a registration statement that has become effective or been declared effective under the Securities Act and that continues to be effective at the time of such transfer or (iii) that has been sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, may, upon surrender of such Note for exchange to the Note Registrar in accordance with the provisions of thisSection 2.05, be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which shall not bear the restrictive legend required by thisSection 2.05(c) and shall not be assigned a restricted CUSIP number. The Company shall instruct the Custodian in writing to so surrender any Global Note as to which any of the conditions set forth in clause (i) through (iii) of the immediately preceding sentence have been satisfied, and, upon such instruction, the Custodian shall so surrender such Global Note for exchange; and any new Global Note so exchanged therefor shall not bear the restrictive legend specified in thisSection 2.05(c) and shall not be assigned a restricted CUSIP number. The Company shall promptly notify the Trustee upon the occurrence of the Resale Restriction Termination Date and promptly after a registration statement, if any, with respect to the Notes or any Common Stock issued upon conversion of the Notes has been declared effective under the Securities Act.

Notwithstanding any other provisions of this Indenture (other than the provisions set forth in thisSection 2.05(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.

The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints The Depository Trust Company to act as Depositary with respect to each Global Note. 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.

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 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 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 issued as a Physical Note, the Company shall execute, and the Trustee, upon receipt of an Officers’ Certificate 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 thisSection 2.05(c) shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, 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.

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.

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

None of the Note Registrar, the Trustee or the Conversion Agent shall have any obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among the Depositary participants, members or beneficial owners in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof. None of the Trustee, the Conversion Agent or any of their agents shall have any responsibility for any actions taken or not taken by the Depositary.

(d) Until the Resale Restriction Termination Date, any stock certificate or book-entry representing Common Stock issued upon conversion of a Note shall bear (in the case of a stock certificate) or have associated with it (in the case of a book-entry) a legend in substantially the following form (unless such Common Stock has been transferred pursuant to an effective registration statement under the Securities Act and that continues to be effective at the time of such transfer, or transferred pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, or such Common Stock has been issued upon conversion of a Note that has transferred pursuant to an effective registration statement under the Securities Act that continues to be effective at the time of such transfer, or pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, or unless otherwise agreed by the Company with written notice thereof to the Trustee and any Transfer Agent for the Common Stock):

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER:

(1)

REPRESENTS THAT IT AND ANY ACCOUNT FOR WHICH IT IS ACTING IS A “QUALIFIED INSTITUTIONAL BUYER” (WITHIN THE MEANING OF RULE 144A UNDER THE SECURITIES ACT) AND THAT IT EXERCISES SOLE INVESTMENT DISCRETION WITH RESPECT TO EACH SUCH ACCOUNT, AND

(2)

AGREES FOR THE BENEFIT OF ACORDA THERAPEUTICS, INC. (THE “COMPANY”) THAT IT WILL NOT OFFER, SELL, PLEDGE OR OTHERWISE TRANSFER THIS SECURITY OR ANY BENEFICIAL INTEREST HEREIN PRIOR TO THE DATE THAT IS THE LATER OF (X) ONE YEAR AFTER THE LAST ORIGINAL ISSUE DATE OF THE SERIES OF NOTES UPON THE CONVERSION OF WHICH THIS SECURITY WAS ISSUED OR SUCH SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER THE SECURITIES ACT OR ANY SUCCESSOR PROVISION THERETO AND (Y) SUCH LATER DATE, IF ANY, AS MAY BE REQUIRED BY APPLICABLE LAW, EXCEPT:

(A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, OR

(B) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT, OR

(D) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

PRIOR TO THE REGISTRATION OF ANY TRANSFER IN ACCORDANCE WITH CLAUSE (2)(D) ABOVE, THE COMPANY AND THE TRANSFER AGENT FOR THE COMPANY’S COMMON STOCK RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO DETERMINE THAT THE PROPOSED TRANSFER IS BEING MADE IN COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

Any such Common Stock (i) as to which such restrictions on transfer shall have expired in accordance with their terms, (ii) that has been transferred pursuant to an effective registration statement under the Securities Act that continues to be effective at the time of such transfer or (iii) that has been sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, may, upon surrender of the certificates representing such shares of Common Stock for exchange in accordance with the procedures of the Transfer Agent for the Common Stock, or upon request for any shares of Common Stock represented by a book entry, be exchanged for a new certificate or certificates or updated book entry or entries, as applicable, for a like aggregate number of shares of Common Stock, which shall not bear the restrictive legend required by thisSection 2.05(d).

(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 immediately 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). The Company shall cause any Note that is repurchased or owned by it to be surrendered to the Trustee for cancellation in accordance withSection 2.08.

Section 2.06 Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become mutilated or be destroyed, lost or stolen, the Company shall issue and the Trustee or an authenticating agent appointed by the Trustee shall authenticate and deliver, a new Note, bearing a registration number not contemporaneously outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note shall furnish to the Company, to the Trustee and, if

applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless from any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

The Trustee or such authenticating agent may authenticate any such substituted Note and deliver the same upon the receipt of such security or indemnity as the Trustee, the Company and, if applicable, such authenticating agent may reasonably require. No service charge shall be imposed by the Company, the Trustee, the Note Registrar, anyco-Note Registrar or the Paying Agent upon the issuance of any substitute Note, but the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax required in connection therewith as a result of the name of the Holder of the new substitute Note being different from the name of the Holder of the old Note that became mutilated or was destroyed, lost or stolen. In case any Note that has matured or is about to mature or has been surrendered for required repurchase or is about to be converted in accordance withArticle 14 shall become mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, evidence satisfactory to the Company, the Trustee and, if applicable, any Paying Agent or Conversion Agent of the destruction, loss or theft of such Note and of the ownership thereof.

Every substitute Note issued pursuant to the provisions of thisSection 2.06 by virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set forth in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement, payment, Optional Mandatory Conversion, conversion or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement, payment, Optional Mandatory Conversion, conversion or repurchase of negotiable instruments or other securities without their surrender.

Section 2.07 Temporary Notes. Pending the preparation of Physical Notes, the Company may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon written request of the Company, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any authorized denomination, and substantially in the form of the Physical Notes but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be executed by the Company and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Physical

Notes. Without unreasonable delay, the Company shall execute and deliver to the Trustee or such authenticating agent Physical Notes (other than any Global Note) and thereupon any or all temporary Notes (other than any Global Note) may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant toSection 4.02 and the Trustee or such authenticating agent shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of Physical Notes. Such exchange shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Physical Notes authenticated and delivered hereunder.

Section 2.08 Cancellation of Notes Paid, Converted, Etc. The Company shall cause all Notes surrendered for the purpose of payment, repurchase, Optional Mandatory Conversion, 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 delivered to the Trustee for cancellation. All Notes delivered to the Trustee shall be canceled promptly by the Trustee. Except for any Notes surrendered for registration of transfer or exchange, or as otherwise expressly permitted by any of the provisions of this Indenture, no Notes shall be authenticated in exchange for any Notes canceled as provided herein. The Trustee shall dispose of canceled Notes in accordance with its customary procedures and shall deliver a certificate of such cancellation to the Company, at the Company’s written request in a Company Order.

Section 2.09 CUSIP and ISIN Numbers. The Company in issuing the Notes may use “CUSIP” numbers and ISIN 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 Company shall promptly notify the Trustee in writing of any change in the “CUSIP” or ISIN numbers.

Section 2.10 Additional Notes; Repurchases. The Company may, without the consent of the Holders and notwithstandingSection 2.01, reopen this Indenture and issue additional Notes hereunder with the same terms as the Notes initially issued hereunder (other than differences in the issue date, the issue price and any interest accrued prior to the issue date of such additional Notes) up to an aggregate principal amount of $210,000,000 for all then-outstanding Notes issued under this Indenture;provided that if any such additional Notes are not fungible with the Notes previously issued hereunder for U.S. federal income tax 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 Officers’ Certificate and an Opinion of Counsel, such Officers’ Certificate and Opinion of Counsel to cover such matters, in addition to those required bySection 18.05, 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. 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 withSection 2.08 and such Notes shall no longer be considered outstanding under this Indenture upon their repurchase.

ARTICLE 3

In the event Covenant Defeasance occurs, certain events (not including those events described inSection 6.01(a),(b),(c),(d),(e),(i), and(j)) will no longer constitute an Event of Default with respect to the Notes.

(vi) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent with respect to such Covenant Defeasance have been complied with.

Section 3.03 Repayment to Company. Any money deposited with the Trustee or any Paying Agent and shares of Common Stock deposited with the Transfer Agent, or then held by the Company, in trust for the payment of the principal (including 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 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 Officers’ 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, such Paying Agent or the Transfer Agent with respect to such trust money and shares of Common Stock, and all liability of the Company as trustee thereof, shall thereupon cease;provided,however, that the Trustee, such Paying Agent or the Transfer Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in The Borough of Manhattan, The City of New York, notice that such money and shares of Common Stock remain unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money and shares of Common Stock then remaining will be repaid or delivered to the Company.

Section 4.06 Rule 144A Information Requirement and Annual Reports. (a) At any time the Company is not subject to Section 13 or 15(d) of the Exchange Act, the Company shall, so long as any of the Notes or any shares of Common Stock issuable upon conversion thereof shall, at such time, constitute “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, promptly provide to the Trustee and, upon written request, any Holder, beneficial owner or prospective purchaser of such Notes or any shares of Common Stock issuable upon conversion of such Notes, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the resale of such Notes or shares of Common Stock pursuant to Rule 144A. The Company shall take such further action as any Holder or beneficial owner of such Notes or such Common Stock may reasonably request to the extent from time to time required to enable such Holder or beneficial owner to sell such Notes or shares of Common Stock in accordance with Rule 144A, as such rule may be amended from time to time.

(b) The Company shall deliver to the Trustee, within 15 days after the same are required to be filed with the Commission, copies of any documents or reports that the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act (giving effect to any grace period provided by Rule12b-25 under the Exchange Act). Any such document or report that the Company files with the Commission via the Commission’s EDGAR system shall be deemed to be delivered with the Trustee for purposes of thisSection 4.06(b) at the time such documents are filed via the EDGAR system; provided that the Trustee has no duty to determine whether any such filings have been made.

(c) The Trustee shall have no duty to review or analyze any report furnished or made available to it. Delivery of the reports and documents described inSection 4.06(b) to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive or actual notice or knowledge 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 Officers’ Certificate).

(d) If, at any time during thesix-month period beginning on, and including, the date that is six months after the last date of original issuance of the Notes, the Company fails to timely file any document or report that it is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act, as applicable (after giving effect to all applicable grace periods thereunder and other than Current Reports on Form8-K), or the Notes are not otherwise freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates or Holders that were the Company’s Affiliates at any time during the three months immediately preceding (as a result of restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes), the Company shall pay Additional Interest on the Notes. Such Additional Interest shall accrue on the Notes at the rate of 0.50% per annum of the principal amount of the Notes outstanding for each day during such period for which the Company’s failure to file has occurred and is continuing or the Notes are not otherwise freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates (or Holders that were the Company’s Affiliates at any time during the three months immediately preceding) without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes. As used in thisSection 4.06(d), documents or reports that the Company is required to “file” with the Commission pursuant to Section 13 or 15(d) of the Exchange Act does not include documents or reports that the Company furnishes to the Commission pursuant to Section 13 or 15(d) of the Exchange Act.

For the avoidance of doubt, Notes represented by a restricted CUSIP in the Depositary’s systems are not freely tradeable.

(f) Interest will be payable in arrears on each Interest Payment Date following accrual as set forth inSection 2.03.

(g) The Additional Interest that is payable in accordance withSection 4.06(d) orSection 4.06(e) shall, subject to the immediately succeeding sentence, be in addition to, and not in lieu of, any Additional Interest that may be payable as a result of the Company’s election pursuant toSection 6.03. In no event shall Additional Interest accrue under the terms of this Indenture at a rate in excess of 0.50% per annum pursuant to this Indenture, regardless of the number of events or circumstances giving rise to the requirement to pay such Additional Interest.

(h) If Additional Interest is payable by the Company pursuant toSection 4.06(d) orSection 4.06(e), the Company shall deliver to the Trustee an Officers’ Certificate to that effect stating (i) the amount of such Additional Interest that is payable and (ii) the date on which such Additional Interest is payable. Unless and until a Responsible Officer of the Trustee receives at the Corporate Trust Office such a certificate, the Trustee may assume without inquiry that no such Additional Interest is payable.

(c) For purposes of determining compliance with thisSection 4.09, in the event that an item of proposed Indebtedness or Disqualified Stock meets the criteria of more than one of the categories of Permitted Debt described inSection 4.09(b) above, or is entitled to be incurred pursuant toSection 4.09(a), the Company will be permitted to classify all or a portion of such item of Indebtedness or Disqualified Stock on the date of its incurrence, or later reclassify all or a portion of such item of Indebtedness or Disqualified Stock (based on circumstances existing on the date of such reclassification), in any manner that complies with this covenant. The accrual of interest, the accrual of dividends, the accretion or amortization of original issue discount, the amortization of debt discount, the payment of interest on any Indebtedness in the form of additional Indebtedness, the payment of interest in the form of additional shares of preferred Capital Stock or Disqualified Stock, the reclassification of Preferred Stock as Indebtedness due to a change in accounting principles, and the payment of dividends on Disqualified Stock in the form of additional shares of the same class of Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock for purposes of this covenant,provided, in each such case, that the amount of any such accrual, accretion or payment is included in fixed charges of the Company as accrued.

(d) The amount of any Indebtedness outstanding as of any date will be:

(i) the accreted value of the Indebtedness, in the case of any Indebtedness issued with original issue discount;

(ii) the aggregate principal amount outstanding, in the case of Indebtedness issued with interest payable in kinds;

(iii) the principal amount of the Indebtedness, in the case of any other Indebtedness; and

(iv) in respect of Indebtedness of another Person secured by a Lien on the assets of the specified Person, the lesser of: (x) the Fair Market Value of such assets at the date of determination; and (y) the amount of the Indebtedness of the other Person.

(e) 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 calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness;provided that if 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 Permitted Refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. Notwithstanding any other provision of thisSection 4.09, the maximum amount of Indebtedness that the Company may incur pursuant to thisSection 4.09 shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies. The principal amount of any Indebtedness incurred to refinance other Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such Permitted Refinancing Indebtedness is denominated that is in effect on the date of such refinancing.

(f) Notwithstanding anything to the contrary set forth herein, the Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, incur (as defined herein) any Indebtedness (including Acquired Debt), that is secured on a pari passu basis with the Note Obligations or higher in priority in right of payment to the Note Obligations, other than Indebtedness permitted pursuant toSection 4.09(b)(iv) (subject to clause limitations set forth in clause (h) of the definition of Permitted Liens).

Section 4.10 Limitations on Liens.

(a) The Company will not, and will not permit any of its Restricted Subsidiaries and Restricted Joint Ventures, in each case, to, directly or indirectly, create, incur or assume any Lien of any kind (other than Permitted Liens) on any asset now owned or hereafter acquired by the Company or such Restricted Subsidiary. For purposes of determining compliance with thisSection 4.10, (i) in the case of Liens that constitute Permitted Liens securing Subordinated Indebtedness, the Notes and any applicable Guarantee are secured by a Lien on such property or

assets of the Company or such Restricted Subsidiary and the proceeds thereof that is senior in priority to such Liens; and (ii) in all other cases that constitute Permitted Liens, the Notes and the applicable Guarantee are equally and ratably secured with or prior to such Obligation with a Lien on the same assets of the Company or such Restricted Subsidiary, as the case may be.

(b) [intentionally omitted].

(c) The Company will not, and will not permit any of its Restricted Subsidiaries to, create, incur or assume or otherwise cause or suffer to exist or become effective any Lien of any kind upon any of their property or assets, now owned or hereafter acquired which Lien secures Indebtedness and is secured on a pari passu basis with the Note Obligations or higher in priority to the Liens securing the Notes other than Liens permitted pursuant to clause (h) of the definition of Permitted Liens.

Section 4.11 Limitations on Asset Sales.

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale, unless (i) the Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the Fair Market Value (measured as of the date of the definitive agreement with respect to such Asset Sale) of the assets, property or Capital Stock issued or sold or otherwise disposed of; (ii) no Default or Event of Default shall have occurred and be continuing at the time of the consummation of such Asset Sale or would be caused thereby and (iii) at least 75% of the consideration received from such Asset Sale (other than in connection with Investments in Joint Ventures by Company or its Subsidiaries) is, or will be when paid (in the case of milestones, royalties and other deferred payment obligations), in the form of cash or cash equivalents;provided that for purposes of this clause (iii), any DesignatedNon-Cash Consideration received by the Company or such Restricted Subsidiary in respect of such Asset Sale having an aggregate Fair Market Value, taken together with all other DesignatedNon-Cash Consideration received pursuant to this clause (iii), not in excess of 25% of the consideration received from such Asset Sale at the time of the receipt of such DesignatedNon-Cash Consideration, with the Fair Market Value of each item of DesignatedNon-Cash Consideration being measured at the time received and without giving effect to subsequent changes in value, shall be deemed to be cash.

(b) Within 12 months after the receipt of any Net Proceeds by the Company or any Restricted Subsidiary from an Asset Sale, the Company (or the applicable Restricted Subsidiary, as the case may be) may apply such Net Proceeds:

(i) [intentionally omitted];

(ii) to fund commitments to research, development or manufacture the Company’s or a Restricted Subsidiaries’, or their respective collaboration or licensing partners’, products or other potential product candidates as may be required under the terms of a license agreement,co-development agreement or Joint Venture;

(iii) to make Capital Expenditures for the benefit of the business of the Company or any Restricted Subsidiary taken as a whole;

(iv) to purchase, redeem, or otherwise acquire any Notes or 2021 Convertible Notes; or

(v) to acquire other assets that are not classified as current assets under GAAP and that are used or useful in the business of the Company or any Restricted Subsidiary;provided that such assets shall become Collateral pursuant the terms of the Note Security Documents within 30 days (or such longer period as the Collateral Agent may agree in its sole discretion) from the acquisition thereof.

Notwithstanding the foregoing, the Net Proceeds of any Asset Sale by the Company or any Guarantor may be used to make Capital Expenditures or purchase assets for the benefit of a Restricted Subsidiary that is not a Guarantor in satisfaction of the foregoing clause (v) only if the Investment of such Net Proceeds by the Company or such Guarantor in such Restricted Subsidiary would be a Permitted Investment. Pending the final application of any Net Proceeds, the Company (or the applicable Restricted Subsidiary) may temporarily reduce revolving credit borrowings or otherwise invest the Net Proceeds in any manner that is permitted under this Indenture.

(c) Any Net Proceeds from Asset Sales received by the Company or any Restricted Subsidiary in the form of cash that are not applied or invested within 12 months as provided inSection 4.11(b) will constitute “Excess Proceeds.” At any time when the aggregate amount of Excess Proceeds not applied or reinvested in accordance withSection 4.11(b) exceeds $10,000,000 (the amount of Excess Proceeds above $10,000,000, the “Subject Excess Proceeds”), within five days thereafter, the Company will make an offer (each, an “Asset Sale Offer”) to all Holders of Notes, to purchase, prepay or redeem the maximum principal amount of Notes after deducting from such Excess Proceeds all accrued and unpaid interest on the Notes and the amount of all fees and expenses, including premiums, incurred in connection with such purchase, prepayment or redemption (the “Offer Amount”). The offer price in any Asset Sale Offer will be equal to 100% of the aggregate principal amount purchased, prepaid or redeemed, plus accrued and unpaid interest on such principal amount to the date of purchase, subject to the rights of Holders of Notes on the relevant Interest Record Date as and to the extent provided inSection 15.02 hereof, and will be payable in cash. If any Subject Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes tendered in or required to be prepaid or redeemed in connection with such Asset Sale Offer exceeds the Offer Amount, the Company will select the Notes to be purchased, prepaid or redeemed on a pro rata basis (subject to adjustment to maintain the authorized minimum denomination of the Notes), based on the amounts tendered or required to be prepaid or redeemed. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

(d) The Company will comply with the requirements of Rule14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions ofSection 15.02 hereof or thisSection 4.11, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations underSection 15.02 hereof or thisSection 4.11 by virtue of such compliance.

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction or series of transactions, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of the Company (each, an “Affiliate Transaction”) involving aggregate payments or consideration in excess of $1,000,000, unless:

(i) the Affiliate Transaction is on terms that are not materially less favorable to the Company or the relevant Restricted Subsidiary, taken as a whole, than those that would have been obtained in a comparable arms-length transaction by the Company or such Restricted Subsidiary with a Person that is not an Affiliate of the Company or any of its Restricted Subsidiaries; and

(ii) the Company delivers to the Trustee, with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate payments or consideration in excess of $5,000,000, a resolution of the Board of Directors accompanied by an Officers’ Certificate certifying that such Affiliate Transaction complies with thisSection 4.12 and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors.

(ii) transactions between or among the Company and/or its Restricted Subsidiaries;

(iii) transactions with a Person (other than an Unrestricted Subsidiary of the Company) that is an Affiliate of the Company solely because the Company owns, directly or through a Restricted Subsidiary, Capital Stock in, or controls, such Person (and no other Affiliate of the Company owns any interest in such Person except through the Company);

(iv) payment of reasonable fees and reimbursement of expenses of directors, officer and employees of the Company or any of its Restricted Subsidiaries;

(v) any transaction in which the only consideration paid by the Company or any Restricted Subsidiary consists of Capital Stock (other than Disqualified Stock) of the Company or any contribution of capital to the Company;

Section 6.02 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 inSection 6.01(i) orSection 6.01(j) with respect to the Company or any of its Significant Subsidiaries), unless the principal of all of the Notes shall have already become due and payable, either the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding determined in accordance withSection 8.04, by notice in writing to the Company (and to the Trustee if given by Holders), may declare 100% of the principal of, and any accrued and unpaid interest on, all the Notes to be due and payable immediately, and upon any such declaration the same shall become and shall automatically be immediately due and payable, anything contained in this Indenture or in the Notes to the contrary notwithstanding. If an Event of Default specified inSection 6.01(i) orSection 6.01(j)with respect to the Company or any of its Significant Subsidiaries occurs and is continuing, 100% of the principal of, and accrued and unpaid interest, if any, on, all Notes shall become and shall automatically be immediately due and payable.

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, and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay installments of any accrued and unpaid interest upon all Notes and the principal of any and all Notes that shall have become due otherwise than by acceleration (with interest on overdue installments of any accrued and unpaid interest to the extent that payment of such interest is enforceable under applicable law, and on such principal, in each case, at the then-applicable interest rate borne by the Notes at such time) and amounts due to the Trustee pursuant toSection 7.06, and if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) any and all existing Events of Default under this Indenture, other than the nonpayment of the principal of and accrued and unpaid interest, if any, on Notes that shall have become due solely by such acceleration, shall have been cured or waived pursuant toSection 6.09, 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 this Indenture; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon. Notwithstanding anything 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 Fundamental Change Repurchase Price, if applicable) of, or any accrued and unpaid interest 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 6.03 Additional Interest. Notwithstanding anything in this 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 inSection 4.06(b) shall for the first 360 days 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 0.25% per annum of the principal amount of the Notes outstanding for each day during the first 180 days during which such Event of Default is continuing and 0.50% per annum of the principal amount of the Notes outstanding

from the 181st day to, and including, the 360th day during which such Event of Default is continuing. Additional Interest payable pursuant to thisSection 6.03 shall be in addition to, not in lieu of, any Additional Interest payable pursuant toSection 4.06(d) orSection 4.06(e), subject to the second immediately succeeding paragraph. If the Company so elects, such Additional Interest shall be payable as set forth inSection 2.03. On the 361st day after such Event of Default (if the Event of Default relating to the Company’s failure to comply with its obligations underSection 4.06(b) is not cured or waived prior to such 361st day), the Notes shall be immediately subject to acceleration as provided inSection 6.02. 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 inSection 4.06(b). In the event the Company does not elect to pay Additional Interest following an Event of Default in accordance with thisSection 6.03 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 inSection 6.02. No Additional Interest shall accrue pursuant to thisSection 6.03, and no right to declare the principal or other amounts due and payable in respect of the Notes shall exist, commencing on the date that the Event of Default has been cured; provided that such Event of Default is cured during such 360 day period.

In order to elect to pay Additional Interest as the sole remedy during the first 360 days after the occurrence of any Event of Default described in the immediately preceding paragraph, the Company must notify in writing all Holders of the Notes, the Trustee and the Paying Agent (if other than the Trustee) of such election on or before the close of business on the date on which such Event of Default first occurs. Upon the failure to timely give such notice, the Notes shall be immediately subject to acceleration as provided inSection 6.02.

In no event shall Additional Interest accrue under the terms of this Indenture at a rate per year in excess of 0.50%, regardless of the number of events or circumstances giving rise to the requirement to pay such Additional Interest.

Section 6.04 Payments of Notes on Default; Suit Therefor. If an Event of Default described inSection 6.01(a) orSection 6.01(b) shall have occurred and be continuing, the Company shall, upon demand of the Trustee, 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 at the then-applicable interest rate borne by the Notes, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee and Collateral Agent underSection 7.06. If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon the Notes, wherever situated.

In the event there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor on the Notes under Title 11 of the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the

Company or such other obligor, the property of the Company or such other obligor, or in the event of any other judicial proceedings relative to the Company or such other obligor upon the Notes, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of thisSection 6.04, 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 and Collateral Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, the Collateral Agent, each of their 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 and Collateral Agent underSection 7.06; 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 and Collateral Agent any amount due to them for reasonable compensation, expenses, advances and disbursements, including agents and counsel fees, and including any other amounts due to the Trustee and Collateral Agent underSection 7.06, incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, advances and disbursements out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and other property that the Holders of the Notes may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise.

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any 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 this Indenture, or under any of the Notes, may be enforced by the Trustee without the possession of any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, the Collateral Agent, their agents and counsel, be for the ratable benefit of the Holders of the Notes.

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

In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned because of any waiver pursuant toSection 6.09 or any rescission and annulment pursuant toSection 6.02 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 6.05 Application of Monies Collected by Trustee. Any monies or property collected by the Trustee pursuant to thisArticle 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 or property, 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 to the Trustee and Collateral Agent underSection 7.06;

Second, in case the principal of the outstanding Notes shall not have become due and be unpaid, to the payment of any 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 any interest is payable on such Notes and has been collected by the Trustee) upon such overdue payments at the rate of interest then payable on such Note, if any, 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 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, payable upon such overdue amounts at the rate of interest then payable on such Notes, if any, 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 Fundamental Change Repurchase Price and any cash due upon conversion) and any interest without preference or priority of principal over such interest, or of any 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 Fundamental Change Repurchase Price and any cash due upon conversion) and any accrued and unpaid interest; and

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

Section 6.06 Proceedings by Holders. Except to enforce the right to receive payment of principal (including the Fundamental Change Repurchase Price, if applicable) or any interest when due, or the right to receive payment or delivery of the consideration due upon conversion, no Holder of any Note shall have any right by virtue of or by availing of any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other similar official, or for any other remedy hereunder, unless:

(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, and if requested, provided to the Trustee such security or indemnity reasonably satisfactory to it against any loss, liability or expense to be incurred therein or thereby;

(d) the Trustee for 60 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 such60-day period pursuant toSection 6.09, 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 this Indenture to affect, disturb or prejudice the rights of any other Holder, or to obtain or seek to obtain priority over or preference to any other such 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 enforce any right under this 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 thisSection 6.06, 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 this Indenture and any provision of any Note, each Holder shall have the right to receive payment or delivery, as the case may be, of (x) the principal (including 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 this Indenture, or to institute suit for the enforcement of any such payment or delivery, as the case may be, which right shall not be impaired or affected without the consent of such Holder.

Section 6.07 Proceedings by Trustee. In case of an Event of Default, the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law.

Section 6.08 Remedies Cumulative and Continuing. Except as provided in the last paragraph ofSection 2.06, all powers and remedies given by thisArticle 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 this Indenture, and no delay or omission of the Trustee or of any Holder of any of the Notes to exercise any right or power accruing upon any Default or Event of Default shall impair any such right or power, or shall be construed to be a waiver of any such Default or Event of Default or any acquiescence therein; and, subject to the provisions ofSection 6.06, every power and remedy given by thisArticle 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 6.09 Direction of Proceedings and Waiver of Defaults by Majority of Holders. The Holders of a majority of the aggregate principal amount of the Notes at the time outstanding determined in accordance withSection 8.04 shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to the Notes;provided,however, that (a) such direction shall not be in conflict with any rule of law or with this Indenture, and (b) the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may refuse to follow any direction that it determines is unduly prejudicial to the rights of any other Holder (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such direction is unduly prejudicial to any Holder) or that would involve the Trustee in personal liability. The Holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance withSection 8.04 may on behalf of the Holders of all of the Notes waive any past Default or Event of Default hereunder and its consequences except (i) a default in the payment of accrued and unpaid interest, if any, on, or the principal (including the Fundamental Change Repurchase Price, if applicable) of, the Notes when due that has not been cured pursuant to the provisions ofSection 6.01, (ii) a failure by the Company to pay or deliver, as the case may be, the consideration due upon conversion of the Notes or (iii) a default in respect of a covenant or provision hereof which underArticle 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 thisSection 6.09, said Default or Event of Default shall for all purposes of the Notes and this Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

Section 6.10 Notice of Defaults. The Trustee shall, within 90 days after the occurrence and continuance of a Default of which a Responsible Officer has received written notice, deliver to all Holders notice of all Defaults known to a Responsible Officer, unless such Defaults shall have been cured or waived before the giving of such notice;provided that, except in the case of a Default in the payment of the principal of (including 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 protected in withholding such notice if and so long as a committee of Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interests of the Holders.

Section 6.11 Undertaking to Pay Costs. All parties to this Indenture agree, and each Holder of any Note by its acceptance thereof shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant;provided that the provisions of thisSection 6.11 (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 withSection 8.04, 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 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 ofArticle 14.

Section 7.08 Eligibility of Trustee. There shall at all times be a Trustee hereunder which shall be a Person that is eligible pursuant to the Trust Indenture Act (as if the Trust Indenture Act were applicable hereto) to act as such and has a combined capital and surplus of at least $50,000,000. If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of any supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. The Company may not, nor may any Person directly or indirectly controlling, controlled by, or under common control with the Company, serve as Trustee.

(d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of thisSection 7.09 shall become effective upon acceptance of appointment by the successor trustee as provided inSection 7.10.

Section 7.10 Acceptance by Successor Trustee. Any successor trustee appointed as provided inSection 7.09 shall execute, acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as Trustee herein; but, nevertheless, on the written request of the Company or of the successor trustee, the trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions ofSection 7.06, execute and deliver an instrument transferring to such successor trustee all the rights and powers of the trustee so ceasing to act. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a senior claim to which the Notes are hereby made subordinate on all money or property held or collected by such trustee as such, except for funds held in trust for the benefit of Holders of particular Notes, to secure any amounts then due it pursuant to the provisions ofSection 7.06.

No successor trustee shall accept appointment as provided in thisSection 7.10 unless at the time of such acceptance such successor trustee shall be eligible under the provisions ofSection 7.08.

Upon acceptance of appointment by a successor trustee as provided in thisSection 7.10, each of the Company and the successor trustee, at the written direction and at the expense of the Company shall deliver or cause to be delivered notice of the succession of such trustee hereunder to the Holders.

In case at the time such successor to the Trustee shall succeed to the trusts created by this Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by such predecessor trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or an

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

Section 7.12 Trustee’s Application for Instructions from the Company. Any application by the Trustee for written instructions from the Company (other than with regard to any action proposed to be taken or omitted to be taken by the Trustee that affects the rights of the Holders of the Notes under this Indenture) may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective.

Whenever the Company or the Trustee solicits the taking of any action by the Holders of the Notes, the Company or the Trustee may, but shall not be required to, fix in advance of such solicitation, a date as the record date for determining Holders entitled to take such action. The record date if one is selected shall be not more than 15 days prior to the date of commencement of solicitation of such action.

Section 8.02 Proof of Execution by Holders. Subject to the provisions ofSection 7.01,Section 7.02 andSection 9.05, proof of the execution of any instrument by a Holder or its agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be reasonably satisfactory to the Trustee.

In the case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described Persons; and, subject toSection 7.01, the Trustee shall be entitled to accept such Officers’ Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such determination.

At any time prior to (but not after) the evidencing to the Trustee, as provided inSection 8.01, of the taking of any action by the Holders of the percentage of the aggregate principal amount of the Notes specified in this Indenture in connection with such action, any Holder of a Note that is shown by the evidence to be included in the Notes the Holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided inSection 8.02, revoke such action so far as concerns such Note. Except as aforesaid, any such action taken by the Holder of any Note shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Note and of any Notes issued in exchange or substitution

After any such supplemental indenture becomes effective, the Company shall deliver to the Holders a notice briefly describing such supplemental indenture. However, the failure to give such notice to all the Holders, or any defect in the notice, will not impair or affect the validity of the supplemental indenture.

CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE

Section 11.01 Company May Consolidate, Etc. on Certain Terms. Subject to the provisions ofSection 11.02, the Company shall not consolidate with, merge with or into, or sell, convey, transfer or lease all or substantially all of its properties and assets to another Person, unless:

(a) the resulting, surviving or transferee Person (the “Successor Company”), if not the Company, shall be a corporation organized and existing under the laws of the United States of America, any state thereof or the District of Columbia, and the Successor Company (if not the Company) shall expressly assume, by supplemental indenture all of the obligations of the Company under the Notes, this Indenture and the other Transaction Documents; and

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

For purposes of thisSection 11.01, the sale, conveyance, transfer or lease of all or substantially all of the properties and assets of one or more Subsidiaries of the Company to another Person, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the properties and assets of the Company on a consolidated basis, shall be deemed to be the sale, conveyance, transfer or lease of all or substantially all of the properties and assets of the Company to another Person.

Section 11.02 Successor Corporation to Be Substituted. In case of any such consolidation, merger, sale, conveyance, transfer or lease and upon the assumption by the Successor Company, by supplemental indenture and supplements or amendments to the other Transaction Documents, executed and delivered to the Trustee and Collateral Agent satisfactory in form to the Trustee, of the due and punctual payment of the principal of and any accrued and unpaid interest on all of the Notes, the due and punctual delivery or payment, as the case may be, of any consideration due upon conversion of the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Company, such Successor Company (if not the Company) shall succeed to and, except in the case of a lease of all or substantially all of the Company’s properties and assets, shall be substituted for the Company, with the same effect as if it had been named herein as the party of the first part. Such Successor Company thereupon may cause to be signed, and may issue either in its own name or in the name of the Company any or all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such Successor Company instead of the Company and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Notes that previously shall have been signed and delivered by the Officers of the Company to the Trustee for authentication, and any Notes that such Successor Company thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under this Indenture as the Notes theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of any such consolidation, merger, sale, conveyance or transfer (but not in the case of a lease), upon compliance with thisArticle 11 the Person named as the “Company” in the first paragraph of this Indenture (or any successor that shall thereafter have become such in the manner prescribed in thisArticle 11) may be dissolved, wound up and liquidated at any time thereafter and, except in the case of a lease, such Person shall be released from its liabilities as obligor and maker of the Notes and from its obligations under this Indenture and the Notes.

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

Section 11.03 Opinion of Counsel to Be Given to Trustee. No such consolidation, merger, sale, conveyance, transfer or lease shall be effective unless the Trustee and Collateral Agent shall have received an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale, conveyance, transfer or lease and any such assumption and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, complies with the provisions of thisArticle 11.

ARTICLE 12

IMMUNITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS AND DIRECTORS

Section 12.01 Indenture and Notes Solely Corporate Obligations. No recourse for the payment of the principal of or any accrued and unpaid interest on any Note, nor for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement of the Company in this Indenture or in any supplemental indenture or in any Note, nor because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, employee, agent, Officer or director or Subsidiary, as such, past, present or future, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly understood that all such liability is hereby expressly waived and released as a condition of, and as a consideration for, the execution of this Indenture and the issue of the Notes.

ARTICLE 13

GUARANTEES

Section 13.01 Guarantees. (a) Subject to thisArticle 13, each of the Guarantors hereby, as a primary obligor and not merely as surety, jointly and severally, unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee, the Collateral Agent and their successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Company hereunder or thereunder, that:

(i) the principal of, premium, if any, and interest on, the Notes and such other Note Obligations will be promptly paid in full in cash when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Company to the Holders, the Trustee or the Collateral Agent hereunder or thereunder will be promptly paid in full in cash or performed, all in accordance with the terms hereof and thereof, and

(ii) in case of any extension of time of payment or renewal of any Notes or any of such other obligations (including Note Obligations), that same will be promptly paid in full in cash when due or performed in accordance with the terms of the extension or renewal, whether at maturity, by acceleration or otherwise.

Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

(b) The Guarantors hereby agree that their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any amendment, waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company or any other Guarantor, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. Each Guarantor hereby unconditionally and irrevocably waives and agrees not to assert any claim, defense, setoff or counterclaim based on diligence, promptness, presentment, requirements for any demand or notice hereunder including any of the following: (i) any demand for payment or performance and protest and notice of protest; (ii) any notice of acceptance; (iii) any presentment, demand, protest or further notice or other requirements of any kind with respect to any Note Obligation (including any accrued but unpaid interest thereon) becoming immediately due and payable; and (iv) any other notice in respect of any Note Obligation or any part thereof, and any defense arising by reason of any disability or other defense of the Company or any Guarantor. Each Guarantor further unconditionally and irrevocably agrees not to (x) enforce or otherwise exercise any right of subrogation or any right of reimbursement or contribution or similar right against the Company or any Guarantor by reason of any Transaction Document or any payment made thereunder or (y) assert any claim, defense, setoff or counterclaim it may have against the Company or any other Guarantor or set off any of its obligations to the Company or any other Guarantor against obligations of such Guarantor to the Company or such other Guarantor. No obligation of any Guarantor hereunder shall be discharged other than by complete performance. Each Guarantor further waives any right such Guarantor may have under any applicable requirement of law to require the Trustee, the Collateral Agent or any Holder to seek recourse first against the Company or any other Person, or to realize upon any Collateral for any of the Note Obligations, as a condition precedent to enforcing such Guarantor’s liability and obligations under thisArticle 13.

(c) If any Holder, the Trustee or the Collateral Agent is required by any court or otherwise to return any amount paid by the Company or any Guarantor to the Trustee, the Collateral Agent or such Holder, this Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect.

(d) Each Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full in cash of all obligations (including the Note Obligations) guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders, the Trustee and the Collateral Agent, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided inSection 6.02 for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided inArticle 6, such obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Guarantee.

(e) Without limiting the joint and several obligation of the Guarantors to the Trustee, Collateral Agent and Holders, all Guarantors desire to allocate among themselves (collectively, the “Contributing Guarantors”), in a fair and equitable manner, their obligations arising under this Indenture. Accordingly, in the event any payment or distribution is made on any date by a Guarantor (a “Funding Guarantor”) under its Guarantee of the Notes such that its Aggregate Payments exceed its Fair Share as of such date, such Funding Guarantor shall be entitled to a contribution from each of the other Contributing Guarantors in an amount sufficient to cause each Contributing Guarantor’s Aggregate Payments to equal its Fair Share as of such date. “Fair Share” means, with respect to a Contributing Guarantor as of any date of determination, an amount equal to (a) the ratio of (i) the Fair Share Contribution Amount with respect to such Contributing Guarantor, to (ii) the aggregate of the Fair Share Contribution Amounts with respect to all Contributing Guarantors, multiplied by (b) the aggregate amount paid or distributed on or before such date by all Funding Guarantors under its guarantee of the Notes in respect of the obligations guaranteed. “Fair Share Contribution Amount” means, with respect to a Contributing Guarantor as of any date of determination, the maximum aggregate amount of the obligations of such Contributing Guarantor under its guarantee of the Notes that would not render its obligations hereunder or thereunder subject to avoidance as a fraudulent transfer or conveyance under Section 548 of the Bankruptcy Law or any comparable applicable provisions of state law,provided that solely for purposes of calculating the Fair Share Contribution Amount with respect to any Contributing Guarantor for purposes of thisSection 13.01, any assets or liabilities of such Contributing Guarantor arising by virtue of any rights to subrogation, reimbursement or indemnification or any rights to or obligations of contribution hereunder shall not be considered as assets or liabilities of such Contributing Guarantor. “Aggregate Payments” means, with respect to a Contributing Guarantor as of any date of determination, an amount equal to (1) the aggregate amount of all payments and distributions made on or before such date by such Contributing Guarantor in respect of its guarantee of the Notes (including in respect of thisSection 13.01), minus (2) the aggregate amount of all payments received on or before such date by such Contributing Guarantor from the other Contributing Guarantors as contributions under thisSection 13.01. The amounts payable as contributions hereunder shall be determined as of the date on which the related payment or distribution is made by the applicable Funding Guarantor. Each Guarantor is a third party beneficiary to the contribution agreement set forth in thisSection 13.01. Notwithstanding anything to the contrary, the Guarantors shall not have the right to seek contribution from the Company and anynon-paying Guarantor until payment in full in cash of all Note Obligations.

Section 13.02 Limitation onGuarantorLiability. Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of applicable Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Guarantee. To effectuate the foregoing intention, the Trustee, the Collateral Agent, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to the maximum amount that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under thisArticle 13, result in the obligations of such Guarantor under its Guarantee not constituting a fraudulent transfer or conveyance. Each

Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that its Guarantee, and the waivers set forth herein, are knowingly made in contemplation of such benefits.

Section 13.03 Execution and Delivery of Guarantee and Supplemental Indenture. To evidence a Guarantee set forth in Section 13.01, this Indenture will be executed on behalf of each Guarantor by one of its Officers or authorized representatives and, with respect to any Guarantors providing a Guarantee after the date hereof, a Supplemental Indenture substantially in the form attached asExhibit B will be executed on behalf of such Guarantor by one of its Officers.

Each Guarantor hereby agrees that its Guarantee set forth inSection 13.01 will remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Guarantee.

If an Officer whose signature is on this Indenture or on the Guarantee no longer holds that office at the time the Trustee authenticates the Note on which a Guarantee is endorsed, the Guarantee will be valid nevertheless.

The delivery of any Note by the Trustee, after the authentication thereof hereunder, will be deemed to constitute due delivery of the Guarantee set forth in this Indenture on behalf of the Guarantors.

Section 13.04 Guarantors May Consolidate, etc., on Certain Terms.Except as otherwise provided inSection 13.05, a Guarantor may not, directly or indirectly, (1) consolidate with or merge with or into, or (2) sell, convey, transfer or lease all or substantially all of its properties and assets to (whether or not such Guarantor is the surviving Person), any other Person, other than the Company or another Guarantor, unless:

(a) immediately after giving effect to that transaction, no Default or Event of Default has occurred and is continuing or would be caused thereby; and

(b) either:

(i) the Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such consolidation or merger (if other than the Company or another Guarantor) is an entity organized under the laws of the United States and otherwise reasonably acceptable to the Trustee and expressly assumes, by executing and delivering a supplemental indenture to the Trustee and the Collateral Agent that is satisfactory in form to the Trustee in accordance withArticle 10 hereof and any other agreements reasonably satisfactory to the Trustee and the Collateral Agent, all of the obligations of that Guarantor under its Guarantee, this Indenture and all appropriate Note Security Documents; or

(ii) such transaction is permitted bySection 4.08 andSection 4.11.

In case of any such consolidation, merger, sale, conveyance, transfer or lease and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Guarantee of such Guarantor and the due

and punctual performance of all of the covenants and conditions of this Indenture to be performed by such Guarantor, such successor Person will succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor Person thereupon may cause to be signed any or all of the Guarantees to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee;provided, however, that the Guarantee of such successor Person will remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Guarantee. All the Guarantees so issued will in all respects have the same legal rank and benefit under this Indenture as the Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Guarantees had been issued at the date of the execution.

Except as set forth inArticle 4, and notwithstandingSection 13.04(a),Section 13.04(b)(i) andSection 13.04(b)(ii) above, nothing contained in this Indenture or in any of the Notes will prevent any consolidation, amalgamation or merger of a Guarantor with or into the Company or another Guarantor, or will prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Company or another Guarantor.

Section 13.05 Releases. The Guarantee of any Guarantor, and the Collateral Agent’s Lien on the Collateral of such Guarantor, will be automatically released:

(a) in connection with any sale or other disposition of all of the Capital Stock or all or substantially all of the assets of a Guarantor (including by way of merger or consolidation) to such Person that is not the Company or a Guarantor if the sale or other Disposition does not violateSection 4.11 and the other provisions of this Indenture;

(b) upon the liquidation or dissolution of such Guarantor following the transfer of all of its assets to the Company or another Guarantor as permitted hereunder.

If the Guarantee of any Guarantor or all or substantially all of the assets of a Guarantor or the Capital Stock of any Guarantor are sold or disposed of in the manner described in clauses (a) or (b) above, and such Guarantor (or as the context may require, Collateral) is released, the Company shall deliver to the Trustee and Collateral Agent an Officers’ Certificate stating and certifying the identity of the released Guarantor (any/or the applicable Collateral), the basis for release in reasonable detail and that such release complies with this Indenture. Upon delivery by the Company to the Trustee and Collateral Agent of an Officers’ Certificate and an Opinion of Counsel to the effect that the conditions of any of clauses (a) or (b) of thisSection 13.05 have been met with respect to a Guarantor (or such Collateral) in accordance with the provisions of this Indenture, the Trustee and Collateral Agent, as applicable, will execute any documents reasonably requested that are necessary or advisable in order to evidence the release of such Guarantor from its obligations under its Guarantee and/or the applicable Note Security Documents. Any Guarantor not released from its obligations under its Guarantee as provided in thisSection 13.05 will remain liable for the full amount of principal of and interest and premium, if any, on the Notes and for the other obligations (including the Note Obligations) of any Guarantor under this Indenture as provided in thisArticle 13 notwithstanding the release of any other Guarantor.

Section 13.06 Reliance. Each Guarantor hereby assumes responsibility for keeping itself informed of the financial condition of the Company, each other Guarantor and any other guarantor,

maker or endorser of any Note Obligation or any part thereof, and of all other circumstances bearing upon the risk of nonpayment of any Note Obligation or any part thereof that diligent inquiry would reveal, and each Guarantor hereby agrees that the Trustee, the Collateral Agent and each Holder shall not have any duty to advise any Guarantor of information known to it regarding such condition or any such circumstances. In the event any of the Trustee, the Collateral Agent or any Holder, in its sole discretion, undertakes at any time or from time to time to provide any such information to any Guarantor, then the Trustee, Collateral Agent or such Holder shall be under no obligation to (a) undertake any investigation not a part of its regular business routine, (b) disclose any information that such Person, pursuant to accepted or reasonable commercial finance or banking practices, wishes to maintain confidential or (c) make any future disclosures of such information or any other information to any Guarantor.

(iii) If, in respect of any Conversion Date (or one of the periods described in the third immediately succeeding set of parentheses, as the case may be), the Company elects to deliver a notice (the “Settlement Notice”) of the relevant Settlement Method in respect of such Conversion Date (or such period, as the case may be), the Company shall deliver such Settlement Notice in writing to the Trustee, the Conversion Agent (if other than the Trustee) and converting Holders no later than the close of business on the Trading Day immediately following the relevant Conversion Date (or, in the case of any conversions for which the relevant Conversion Date occurs (x) after the date of issuance of a Mandatory Conversion Notice with respect to the Notes and prior to the related Mandatory Conversion Date in such Mandatory Conversion Notice or (y) on or after September 1, 2024, no later than September 1, 2024). Such Settlement Notice shall specify the relevant Settlement Method and in the case of an election of Combination Settlement, the relevant Settlement Notice shall indicate the Specified Dollar Amount per $1,000 principal amount of Notes. If the Company timely delivers a Settlement Notice electing Combination Settlement in respect of its Conversion Obligation but does not indicate a Specified Dollar Amount per $1,000 principal amount of Notes in such Settlement Notice, the Specified Dollar Amount per $1,000 principal amount of Notes shall be deemed to be $1,000. If the Company does not elect a Settlement Method prior to the deadline set forth in the third immediately preceding sentence, the Company shall no longer have the right to elect Cash Settlement or Combination Settlement and the Company shall be deemed to have elected Physical Settlement in respect of its Conversion Obligation.

(iv) The cash, shares of Common Stock or combination of cash and shares of Common Stock in respect of any conversion of Notes (the “Settlement Amount”) shall be computed as follows:

(A) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Physical Settlement, 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 in effect on the Conversion Date;

(B) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Cash Settlement, the Company shall pay to the converting Holder in respect of each $1,000 principal amount of Notes being converted cash in an amount equal to the sum of the Daily Conversion Values for each of the 40 consecutive Trading Days during the related Observation Period; and

(C) if the Company elects (or is deemed to have elected) to satisfy its Conversion Obligation in respect of such conversion by Combination Settlement, the Company shall pay or deliver, as the case may be, in respect of each $1,000 principal amount of Notes being converted, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 40 consecutive Trading Days during the related Observation Period.

(v) The Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable) shall be determined by the Company promptly following the last day

of the Observation Period. Promptly after such determination of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of delivering any fractional share of Common Stock, the Company shall notify the Trustee and the Conversion Agent (if other than the Trustee) of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of delivering fractional shares of Common Stock. The Trustee and the Conversion Agent (if other than the Trustee) shall have no responsibility for any such determination.

(b) Subject toSection 14.02(e), before any Holder of a Note shall be entitled to convert a Note as set forth above, such Holder shall (i) in the case of a Global Note, comply with the Applicable Procedures of the Depositary in effect at that time and, if required, pay funds equal to any interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth inSection 14.02(h) and (ii) in the case of a Physical Note (1) complete, manually sign and deliver an irrevocable notice to the Conversion Agent as set forth in the Form of Notice of Conversion (or a facsimile thereof) (a “Notice of Conversion”) at the office of the Conversion Agent and state in writing therein the principal amount of Notes to be converted and the name or names (with addresses) in which such Holder wishes the certificate or certificates for any shares of Common Stock to be delivered upon settlement of the Conversion Obligation to be registered, (2) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the Conversion Agent, (3) if required, furnish appropriate endorsements and transfer documents and (4) if required, pay funds equal to any interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth inSection 14.02(h). The Trustee (or if different, the Conversion Agent) shall notify the Company of any conversion pursuant to thisArticle 14 on the Conversion Date for such conversion. No Notice of Conversion with respect to any Notes may be delivered 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 withSection 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 inSection 14.02(b). Except as set forth inSection 14.03(b) andSection 14.07(a), the Company shall pay or deliver, as the case may be, the consideration due in respect of the Conversion Obligation (including the Interest Make-Whole Payment) on the second Business Day immediately following the relevant Conversion Date, if the Company elects Physical Settlement, or on the second Business Day immediately following the last Trading Day of the Observation Period, in the case of any other Settlement Method. If any shares of Common Stock are due to a converting Holder, the Company shall issue or cause to be issued, and deliver (if applicable) to the Conversion Agent or to such Holder, or such Holder’s nominee or nominees, the full number of shares of Common Stock to which such Holder shall be entitled, in book-entry format through the Depositary (if such facilities are then available), in satisfaction of the Company’s Conversion Obligation.

100

(d) In case any Note shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Note so surrendered 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 or Trustee, 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 such shares to be issued in a name other than the Holder’s name, in which case the Holder shall 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 inSection 14.04, no adjustment shall be made for dividends on any shares of Common Stock issued upon the conversion of any Note as provided in thisArticle 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) Subject toSection 14.02(i) and except as set forth below, upon any conversion, a Holder shall not receive any separate cash payment for accrued and unpaid interest, if any. Subject toSection 14.02(i) and 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 not including, the relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but not including, the relevant Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon a conversion of Notes into a combination of cash and shares of Common Stock, accrued and unpaid interest will be deemed to be paid first out of the cash paid upon such conversion. Notwithstanding the foregoing, if Notes are converted after the close of business on an Interest Record Date, Holders of such Notes as of the close of business on such Interest Record Date shall receive the full amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period from the close of business on any Interest Record Date to the 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 conversions following the Interest Record Date immediately preceding the Maturity Date; (2) if the Company has specified a Mandatory

101

Conversion Date or Fundamental Change Repurchase Date that is after an Interest Record Date and on or prior to the Business Day immediately following the date on which the corresponding interest payment is made; (3) to the extent of any Defaulted Amounts, if any Defaulted Amounts exists at the time of conversion with respect to such Note; or (4) for any conversion of Notes as to which an Interest Make-Whole Payment is payable (or Section 14.02(i) is otherwise applicable). Therefore, for the avoidance of doubt, all Holders of record on the Interest Record Date immediately preceding the Maturity Date shall receive the full interest payment due on the Maturity Date regardless of whether their Notes have been converted following such Interest Record Date.

(i) Upon any conversion, other than a conversion in connection with a Make-Whole Fundamental Change, the Company will, in addition to the other consideration payable or deliverable in connection with such conversion, make an interest make-whole payment to the converting Holder equal to the sum of the remaining scheduled payments of interest that would have been made on the Notes to be converted had such Notes remained outstanding from the Conversion Date through June 1, 2023 (the “Interest Make-Whole Payment”); provided that if the applicable Conversion Date occurs after the close of business on an Interest Record Date but prior to the open of business on the Interest Payment Date corresponding to such Interest Record Date, the Company shall not pay accrued interest to any converting Holder and will instead pay the full amount of the relevant interest payment on such Interest Payment Date to the Holder of record on such Interest Record Date. In such case, the Interest Make-Whole Payment to such converting Holder will equal all remaining interest payments, starting with the next Interest Payment Date for which interest has not been provided for until June 1, 2023. The Company may pay the Interest Make-Whole Payment in cash or, if the Authorized Share Conversion Cap and the Beneficial Ownership Limitations would not limit such payment, by delivery of shares of Common Stock, with the value of each share of Common Stock so delivered equal to 95% of the simple average of the Daily VWAP for the 10 Trading Days ending on, and including, the Trading Day immediately preceding the Conversion Date. The Company shall notify the converting Holder of the Company’s election to pay any part of the Interest Make-Whole Payment in shares of Common Stock no later than the close of business on the Trading Day immediately following the relevant Conversion Date.

(j) 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 (if the Company elects to satisfy the related Conversion Obligation by Physical Settlement) or the last Trading Day of the relevant Observation Period (if the Company elects to satisfy the related Conversion Obligation by Combination Settlement), as the case may be. Upon a conversion of Notes, such Person shall no longer be a Holder of such Notes surrendered for conversion.

(k) The Company shall not issue any fractional share of Common Stock upon conversion of the Notes (including any shares of Common Stock to be issued in connection with an Interest Make-Whole Payment) and shall instead pay cash in lieu of delivering any fractional share of Common Stock issuable upon conversion based on the Daily VWAP for the relevant Conversion Date (in the case of Physical Settlement) or based on the Daily VWAP for the last Trading Day of the relevant Observation Period (in the case of Combination Settlement). For each Note surrendered for conversion, if the Company has elected (or is deemed to have elected)

102

Combination Settlement, the full number of shares that shall be issued upon conversion thereof shall be computed on the basis of the aggregate Daily Settlement Amounts for the relevant Observation Period and any fractional shares remaining after such computation shall be paid in cash.

Section 14.03 Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental Changes. (a) If the Effective Date of a Make-Whole Fundamental Change occurs 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 of Common Stock (the “Additional Shares”), as described below. 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 theproviso in clause (b) of the definition thereof, the 25th Trading Day immediately following the Effective Date of such 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 pursuant toSection 14.03(a), the Company shall satisfy the related Conversion Obligation based on the Conversion Rate as increased to reflect the Additional Shares pursuant to the table below by, at the Company’s option, Physical Settlement, Cash Settlement or Combination Settlement in accordance withSection 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 such 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. In such event, the Conversion Obligation shall be paid to Holders in cash on the second Business Day following the Conversion Date. The Company shall notify the Holders of Notes (which notification may be made through the Depositary), the Trustee and the Conversion Agent (if other than the Trustee) of the Effective Date of any Make-Whole Fundamental Change and issue a press release announcing such Effective Date 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 below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”) and the price paid (or deemed to be paid) per share of the Common Stock in the Make-Whole Fundamental Change (the “Stock Price”). If the holders of the Common Stock receive in exchange for their Common Stock only cash in a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock over the 10 Trading Day period ending on, and including, the Trading Day immediately

103

preceding the Effective Date of the Make-Whole Fundamental Change. The Board of Directors shall make appropriate adjustments to the Stock Price, in its good faith determination, to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where theEx-Dividend Date, Effective Date (as such term is used inSection 14.04) or expiration date of the event occurs during such 10 consecutive Trading Day period.

(d) 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 number of Additional Shares 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 inSection 14.04.

(e) The following table sets forth the number of Additional Shares of Common Stock by which the Conversion Rate shall be increased per $1,000 principal amount of Notes pursuant to thisSection 14.03 for each Stock Price and Effective Date set forth below:

(f) The exact Stock Price and Effective Date 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 number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Prices and the earlier and later Effective Dates, as applicable, based on a365-day year;

(ii) if the Stock Price is greater than $35.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant toSection 14.03(d)), no Additional Shares shall be added to the Conversion Rate; and

(iii) if the Stock Price is less than $1.78 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant toSection 14.03(d)), no Additional Shares shall be added to the Conversion Rate.

104

Notwithstanding the foregoing, in no event shall the Conversion Rate per $1,000 principal amount of Notes exceed 561.7977 shares of Common Stock, subject to adjustment in the same manner as the Conversion Rate pursuant toSection 14.04.

(g) Nothing in thisSection 14.03 shall prevent an adjustment to the Conversion Rate pursuant toSection 14.04 in respect of a Make-Whole Fundamental Change.

Section 14.04 Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time 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), 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 thisSection 14.04, 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:


CR’ = CR₀	×	OS’
CR’ = CR₀	×	OS₀



where,

CR₀	=	the Conversion Rate in effect immediately prior to the open of business on theEx-Dividend Date for 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 open of business on suchEx-Dividend Date or Effective Date;

OS₀	=	the number of shares of Common Stock outstanding immediately prior to the open of business on suchEx-Dividend Date or Effective Date (before giving effect to any such dividend, distribution, split or combination); 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 thisSection 14.04(a) shall become effective immediately after the open of business on theEx-Dividend 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 thisSection 14.04(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.

105

(b) If the Company issues to all or substantially all holders of the Common Stock any rights, options or warrants (other than pursuant to a stockholder rights plan) entitling them, for a period of not more than 60 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 over 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:


CR’ = CR₀	×	OS₀ + X
CR’ = CR₀	×	OS₀ + Y



where,

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

CR’	=	the Conversion Rate in effect immediately after the open of business on suchEx-Dividend Date;

OS₀	=	the number of shares of Common Stock outstanding immediately prior to the open of business on suchEx-Dividend 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 thisSection 14.04(b) shall be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the open of business on theEx-Dividend Date for such issuance. To the extent that 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, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if suchEx-Dividend Date for such issuance had not occurred.

For purposes of thisSection 14.04(b), in determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of the Common Stock at less than such 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 for such issuance, and in determining the aggregate offering price of such shares of

106

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 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 toSection 14.04(a) orSection 14.04(b) (or will be so effected in accordance with the second sentence ofSection 14.04(j)), Article 1 except as set forth inSection 14.13, rights issued under a stockholder rights plan, (ii) dividends or distributions paid exclusively in cash as to which the provisions set forth inSection 14.04(d) shall apply, and (iii) Spin-Offs as to which the provisions set forth below in thisSection 14.04(c) shall apply, (any of such shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire Capital Stock or other securities, the “Distributed Property”), then the Conversion Rate shall be increased based on the following formula:


CR’ = CR₀	×	SP₀
CR’ = CR₀	×	SP₀ – FMV



where,

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

CR’	=	the Conversion Rate in effect immediately after the open of business on suchEx-Dividend 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 theEx-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 theEx-Dividend Date for such distribution.

Any increase made under the portion of thisSection 14.04(c) above shall become effective immediately after the open of business on theEx-Dividend 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 theEx-Dividend Date for the distribution. If the Board of Directors determines the “FMV” (as defined above) of any distribution for purposes of thisSection 14.04(c)

107

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 theEx-Dividend Date for such distribution.

With respect to an adjustment pursuant to thisSection 14.04(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:


CR’ = CR₀	×	FMV₀ + MP₀
CR’ = CR₀	×	MP₀



where,

CR₀	=	the Conversion Rate in effect immediately prior to the end of the Valuation Period;

CR’	=	the Conversion Rate in effect immediately after the end of the Valuation Period;

FMV₀	=	the average of the Last Reported Sale Prices of the 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 inSection 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, theEx-Dividend Date of theSpin-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 occur at the close of business on the last Trading Day of the Valuation Period;provided that (x) in respect of any conversion of Notes for which Physical Settlement is applicable, if the relevant Conversion Date occurs during the Valuation Period, references to “10” in the preceding paragraph shall be deemed to be replaced with such lesser number of Trading Days as have elapsed from, and including, theEx-Dividend Date of suchSpin-Off to, and including, the Conversion Date in determining the Conversion Rate and (y) in respect of any conversion of Notes for which Cash Settlement or Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation Period for such conversion and within the Valuation Period, references to “10” in the preceding paragraph shall be deemed to be replaced with such lesser number of Trading Days as have elapsed from, and including, theEx-Dividend Date of suchSpin-Off to, and including, such Trading Day in determining the Conversion Rate as of such Trading Day. If any dividend or distribution that constitutes aSpin-Off is declared but not paid or made, the Conversion Rate shall be immediately decreased, effective as of the date the Board of Directors determines not to pay or make such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared or announced.

108

For purposes of thisSection 14.04(c) (and subject in all respect toSection 14.13), 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 thisSection 14.04(c) (and no adjustment to the Conversion Rate under thisSection 14.04(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 thisSection 14.04(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this 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 andEx-Dividend Date 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 thisSection 14.04(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 Optional Mandatory Conversion 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 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 Optional Mandatory Conversion or purchase and (2) in the case of such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights, options and warrants had not been issued.

For purposes ofSection 14.04(a),Section 14.04(b) and thisSection 14.04(c), if any dividend or distribution to which thisSection 14.04(c) is applicable also includes one or both of:

(A) a dividend or distribution of shares of Common Stock to whichSection 14.04(a) is applicable (the “Clause A Distribution”); or

(B) a dividend or distribution of rights, options or warrants to whichSection 14.04(b) is applicable (the “Clause B Distribution”),

109

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 thisSection 14.04(c) is applicable (the “Clause C Distribution”) and any Conversion Rate adjustment required by thisSection 14.04(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 bySection 14.04(a) andSection 14.04(b) with respect thereto shall then be made, except that, if determined by the Company (I) the“Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution shall be deemed to be theEx-Dividend 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 open of business on suchEx-Dividend Date or Effective Date” within the meaning ofSection 14.04(a) or “outstanding immediately prior to the open of business on suchEx-Dividend Date” within the meaning ofSection 14.04(b).

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


CR’ = CR₀	×	SP₀
CR’ = CR₀	×	SP₀ – C



where,

CR₀	=	the Conversion Rate in effect immediately prior to the open of business on theEx-Dividend Date for such dividend or distribution;

CR’	=	the Conversion Rate in effect immediately after the open of business on theEx-Dividend Date for such dividend or distribution;

SP₀	=	the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding theEx-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 thisSection 14.04(d) shall become effective immediately after the open of business on theEx-Dividend 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 theEx-Dividend Date for such cash dividend or distribution.

110

(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 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 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:


CR’ = CR₀	×	AC + (SP’×OS’)
CR’ = CR₀	×	OS₀ × SP’


where,

CR₀	=	the Conversion Rate in effect immediately prior to 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;

CR’	=	the Conversion Rate in effect immediately after 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;

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 date 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 date 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 thisSection 14.04(e) shall occur 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;provided that (x) in respect of any conversion of Notes for which Physical Settlement is applicable, if the relevant Conversion Date occurs during the 10 Trading Days immediately following, and including, the Trading Day next succeeding the expiration date of any tender or exchange offer, references to “10” or “10th” in the preceding paragraph shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the date that such tender or

111

exchange offer expires to, and including, the Conversion Date in determining the Conversion Rate and (y) in respect of any conversion of Notes for which Cash Settlement or Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation Period for such conversion and within the 10 Trading Days immediately following, and including, the Trading Day next succeeding the expiration date of any tender or exchange offer, references to “10” or “10th” in the preceding paragraph shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the expiration date of such tender or exchange offer to, and including, such Trading Day in determining the Conversion Rate as of such Trading Day. If the Company is obligated to purchase shares of Common Stock pursuant to any such tender or exchange offer described inSection 14.04(e) but is permanently prevented by applicable law from effecting any such purchase or all such purchases are rescinded, the applicable Conversion Rate will 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 made.

(f) Notwithstanding thisSection 14.04 or any other provision of this Indenture or the Notes, if a Conversion Rate adjustment becomes effective on anyEx-Dividend Date, and a Holder that has converted its Notes on or after suchEx-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 underSection 14.02(j) based on an adjusted Conversion Rate for suchEx-Dividend Date, then, notwithstanding the Conversion Rate adjustment provisions in thisSection 14.04, the Conversion Rate adjustment relating to suchEx-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 thisSection 14.04, 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 deliver to the Holder of each Note 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.

112

(i) Notwithstanding anything to the contrary in thisArticle 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 and outstanding as of the date the Notes were first issued;

(iv) upon the repurchase of any of the Common Stock pursuant to an open market share purchase program or otherbuy-back transaction, including structured or derivative transactions such as accelerated share repurchase transactions or similar forward repurchase transactions, or otherbuy-back transaction, that is not a tender offer or exchange offer of the kind described inSection 14.04(e);

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

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

(j) All calculations and other determinations under thisArticle 14 shall be made by the Company and shall be made to the nearestone-ten thousandth (1/10,000th) of a share. If an adjustment to the Conversion Rate otherwise required pursuant toSection 14.04(a) through(e) would result in a change of less than one percent to the Conversion Rate, then, notwithstanding the foregoing, the Company may, at its election, defer and carry forward such adjustment, except that all such deferred adjustments must be given effect immediately upon the earliest to occur of the following: (i) when all such deferred adjustments would result in an aggregate change of at least 1% to the Conversion Rate; (ii) on the Conversion Date for any Notes (in the case of Physical Settlement); (iii) on each Trading Day of any Observation Period related to any conversion of Notes (in the case of Cash Settlement or Combination Settlement); (iv) on the effective date of any Fundamental Change and/or Make-Whole Fundamental Change; (v) the date, if any, on which the Company provides a Mandatory Conversion Notice; and (vi) any Mandatory Conversion Date, in each case, unless the adjustment has already been made.

(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 Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such

113

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. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

(l) For purposes of thisSection 14.04, 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.

Section 14.05 Adjustments of Prices.Whenever any provision of this Indenture requires the Company to calculate the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts over a span of multiple days (including, without limitation, an Observation Period and the period for determining the Stock Price for purposes of a Make-Whole Fundamental Change), the Board of Directors shall make appropriate adjustments 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 theEx-Dividend Date, Effective Date or expiration date, as the case may be, of the event occurs, at any time during the period when the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts are to be calculated.

Section 14.06 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 delivery of the maximum number of Additional Shares pursuant toSection 14.03 and that at the time of computation of such number of shares, all such Notes would be converted by a single Holder and that Physical Settlement were applicable).

Section 14.07 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 “Merger Event”), then, at and after the effective time of such Merger Event, the right to convert each $1,000 principal amount of Notes shall be changed into a right to convert

114

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 Merger 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 such Merger Event and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture permitted underSection 10.01(g) providing for such change in the right to convert each $1,000 principal amount of Notes;provided,however, that at and after the effective time of the Merger Event (A) the Company shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon conversion of Notes in accordance withSection 14.02 and (B) (I) any amount payable in cash upon conversion of the Notes in accordance withSection 14.02 shall continue to be payable in cash, (II) any shares of Common Stock that the Company would have been required to deliver upon conversion of the Notes in accordance withSection 14.02 shall instead be deliverable in the amount and type of Reference Property that a holder of that number of shares of Common Stock would have received in such Merger Event and (III) the Daily VWAP shall be calculated based on the value of a unit of Reference Property.

If the Merger 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 stockholder election), then (i) the Reference Property into which the Notes will be convertible shall be deemed to be the weighted average of 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 Merger Event, then for all conversions for which the relevant Conversion Date occurs after the effective date of such Merger 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 toSection 14.03),multiplied by the price paid per share of Common Stock in such Merger Event and (B) the Company shall satisfy the Conversion Obligation by paying cash to converting Holders on the second Business Day immediately following the relevant Conversion Date. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average as soon as practicable after such determination is made.

The supplemental indenture described in the second immediately preceding paragraph shall provide for anti-dilution and other adjustments that shall be as nearly equivalent as is possible to the adjustments provided for in thisArticle 14. If, in the case of any Merger Event, the Reference Property includes shares of stock, securities or other property or assets (including cash or any combination thereof) of a Person other than the successor or purchasing corporation, as the case may be, in such Merger Event, then such supplemental indenture shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including the provisions providing for the purchase rights set forth inArticle 15.

115

(b) When the Company executes a supplemental indenture pursuant toSection 14.07(a), the Company shall promptly file with the Trustee an Officers’ 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 Merger Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly deliver notice thereof to all Holders. The Company shall cause notice of the execution of such supplemental indenture to be delivered to each Holder within 20 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 Merger Event unless its terms are consistent with thisSection 14.07. None of the foregoing provisions shall affect the right of a holder of Notes to convert its Notes into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, as set forth inSection 14.01 andSection 14.02 prior to the effective date of such Merger Event.

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

Section 14.08 Certain Covenants.(a) The Company covenants that all shares of Common Stock issued upon conversion of Notes will be fully paid andnon-assessable by the Company and free from all taxes, liens and charges 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 use reasonable best efforts to 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 14.09 Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any Holder 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

116

surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant toSection 14.07 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 suchSection 14.07 or to any adjustment to be made with respect thereto, but, subject to the provisions ofSection 7.01, may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. None of the Trustee, the Conversion Agent or any of their agents shall be responsible for monitoring or determining whether any Beneficial Ownership Limitations, Authorized Share Conversion Cap or Equity Payment Conditions have been met or determining whether the Authorized Share Amendment Date has occurred and shall be entitled to rely conclusively on written notice provided by the Company as to such matters and any other matters with respect to the Common Stock.

Section 14.10 Beneficial Ownership Limitations.(a) Notwithstanding anything to the contrary in this Indenture, no Holder will be entitled to receive shares of Common Stock upon conversion of Notes (including pursuant to any Optional Mandatory Conversion pursuant toSection 16.01) and no conversion of Notes shall take place to the extent (but only to the extent) that such receipt (or conversion) would cause such Holder and its Affiliates to beneficially own shares in excess of the Beneficial Ownership Limitations. For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by the Holder and its Affiliates shall include the number of shares of Common Stock issuable upon conversion of any Notes with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which are issuable upon (i) conversion of the remaining, unconverted principal amount of Notes beneficially owned by the Holder and its Affiliates and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company subject to a limitation on conversion or exercise analogous to the limitation contained herein (including, without limitation, any other Notes) beneficially owned by the Holder and its Affiliates. Except as set forth in the preceding sentence, for purposes of this provision, beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. Any purported delivery of shares of Common Stock upon conversion of the Notes shall be void and have no effect to the extent (but only to the extent) that such delivery would result in the converting Holder violating the Beneficial Ownership Limitations. Solely for the purpose of thisSection 14.10, in the case of Global Notes, “Holder” shall mean a person that holds a beneficial interest in the Notes and not the Depository Trust Company or its nominee.

(b) To the extent that the limitation contained in this provision applies, the determination of whether any Notes are convertible (in relation to other securities beneficially owned by the Holder) and of which principal amount of such Notes are convertible shall be in the sole discretion of the Holder, and the submission of a Notice of Conversion shall be deemed to be the Holder’s determination of whether any Notes may be converted (in relation to other securities beneficially owned by the Holder) and which principal amount such Notes are convertible, in each case subject to the Beneficial Ownership Limitations. To ensure compliance with this restriction,

117

the Holder shall be deemed to represent to the Company each time it delivers a Notice of Conversion that such Notice of Conversion has not violated the restrictions set forth in thisSection 14.10 and the Company shall have no obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder.

(c) For purposes of thisSection 14.10, in determining the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding shares of Common Stock as stated in the most recent of the following: (i) the Company’s most recent periodic or annual report filed with the Commission, as the case may be, (ii) a more recent public announcement by the Company, or (iii) a more recent written notice by the Company or the Company’s transfer agent to such Holder setting forth the number of shares of Common Stock outstanding. Upon the written or oral request of a Holder, the Company shall within two Trading Days confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including the Notes, by the Holder since the date as of which such number of outstanding shares of Common Stock was reported.

(d) The “General Beneficial Ownership Limitation” shall be 9.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon conversion of any Notes held by the Holder. The Holder, upon not less than 61 days’ prior written notice to the Company, may elect a beneficial ownership limit as to such Holder (but not as to any other Holder) (such limit, a “Holder Beneficial Ownership Limitation” and together with the General Beneficial Ownership Limitation, the “Beneficial Ownership Limitations”) that is less than or equal to the General Beneficial Ownership Limitation then applicable to the Holders. Any Holder Beneficial Ownership Limitation will be effective as of (i) the issue date for the Notes, for any notice delivered prior to the issuance of such Notes, and (ii) the 61st day after such notice is delivered to the Company in all other cases.

(e) Any Notes surrendered for conversion (including pursuant to any Optional Mandatory Conversion pursuant toSection 16.01) for which shares of Common Stock are not delivered due to the Beneficial Ownership Limitations shall not be extinguished and, such Holder may either:

(i) request return of the Notes surrendered by such Holder for Conversion, after which the Company shall deliver such Notes to such Holder within two trading days after receipt of such request; or

(ii) certify to the Company that the person (or persons) receiving shares of Common Stock upon conversion is not, and would not, as a result of such conversion, become the beneficial owner of shares of Common Stock outstanding at such time in excess of the applicable Beneficial Ownership Limitations, after which the Company shall deliver any such shares of Common Stock withheld on account of such applicable Beneficial Ownership Limitations by the later of (x) the date such shares were otherwise due to such person (or persons) and (y) two Trading Days after receipt of such certification;provided,

118

however, until such time as the affected Holder gives such notice, no person shall be deemed to be the stockholder of record with respect to the shares of Common Stock otherwise deliverable upon conversion in excess of any applicable Beneficial Ownership Limitations. Upon delivery of such notice, the provisions underSection 14.02 shall apply to the shares of Common Stock to be delivered pursuant to such notice.

Section 14.11 Authorized Share Conversion Cap. (a) Notwithstanding anything to the contrary in this Indenture, prior to the Authorized Share Amendment Date, the number of shares of Common Stock deliverable upon conversion of all Notes in the aggregate and satisfaction of the Interest Make-Whole Payments and any interest payments hereunder will be subject to, and shall not exceed, the Authorized Share Conversion Cap.

(b) Prior to the earliest of (i) July 31, 2020, (ii) the Authorized Share Amendment Date and (iii) the commencement of any bankruptcy, insolvency, reorganization or similar proceeding with respect to the Company (such earliest date, the “Full Conversion Date”):

(i) if the Company receives a Notice of Conversion from more than one Holder of Notes for the same Conversion Date and, due to the Authorized Share Conversion Cap or for any other reason, the Company can convert some, but not all, of such Notes submitted for conversion (including the related Interest Make-Whole Payment, if any) on such date into Common Stock, then the Company shall convert from each Holder of Notes electing to have Notes converted on such Conversion Date a pro rata amount of such Holder’s portion of its Notes submitted for conversion based on the principal amount of Notes submitted for conversion on such date by such Holder relative to the aggregate principal amount of all Notes submitted for conversion on such Conversion Date;

(ii) the Company shall be entitled to settle conversions of Notes using Physical Settlement and the Interest Make-Whole Payment in shares of Common Stock up to the Authorized Share Conversion Cap and shall not be required to pay any cash in respect of the shares of Common Stock not delivered; and

(iii) any Notes surrendered for conversion for which any shares of Common Stock are not required to be delivered pursuant to thisSection 14.11 (whether such shares would have been required to be delivered to settle conversions of Notes using Physical Settlement or to settle the Interest Make-Whole Payment in shares of Common Stock) shall not be converted or extinguished and shall instead be returned to the Holders and shall remain outstanding.

(c) If, on or following the Full Conversion Date, the Company receives a Notice of Conversion from one or more Holders of Notes for the same Conversion Date and, due to the Authorized Share Conversion Cap or any other reason, the Company can convert some, but not all, of such Notes submitted for conversion (including the related Interest Make-Whole Payment, if any) into Common Stock, then:

(i) the Company shall be required to settle such conversions using either Cash Settlement or Combination Settlement, at the Company’s election;

119

(ii) if the Company elects Combination Settlement or elects to settle the Interest Make-Whole Payment in shares of Common Stock then the amount of shares of Common Stock to be given to each Holder upon settlement of such conversion (including with respect to shares delivered in satisfaction of the Interest Make-Whole Payment) shall be allocated by the Company on a pro rata basis among Holders surrendering their Notes for conversion on such Conversion Date based on the principal amount of Notes submitted for conversion on such date by such Holder relative to the aggregate principal amount of all Notes submitted for conversion on such Conversion Date; and

(iii) the Company shall be required to pay cash for any portion of the Conversion Obligation payable with regard to Notes surrendered for conversion (including any applicable Interest Make-Whole Payment) and for which shares of Common Stock are unable to be delivered due to the Authorized Share Conversion Cap or any other reason with any such cash payment to be equal to (A) with respect to shares of Common Stock that would have been required to be delivered in connection with an Interest Make-Whole Payment, the excess of the amount of the Interest Make-Whole Payment over the product of (x) the number of shares of Common Stock delivered in connection with such Interest Make-Whole Payment, and (y) 95% of the simple average of the Daily VWAP for the 10 Trading Days ending on and including the Trading Day immediately preceding the applicable Conversion Date, and (B) with respect to shares of Common Stock that would have been required to be delivered other than in connection with an Interest Make-Whole Payment, with respect to each Trading Day during the Observation Period in respect of which shares of Common Stock are not delivered, the number of shares of Common Stock not so delivered in respect of such Trading Day multiplied by the Daily VWAP for such Trading Day.

(d) Prior to the Authorized Share Amendment Date, whenever the Authorized Share Conversion Cap is adjusted as herein provided, the Company shall promptly file with the Trustee and the Conversion Agent an Officers’ Certificate setting forth the Authorized Share Conversion Cap after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until an authorized officer of the Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Authorized Share Conversion Cap and may assume without inquiry that the last Authorized Share Conversion Cap of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Authorized Share Conversion Cap setting forth the adjusted Authorized Share Conversion Cap and the date on which each adjustment becomes effective and shall send such notice of such adjustment of the Authorized Share Conversion Cap to each Holder with a copy to the Trustee and Conversion Agent. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

Section 14.12 Notice to Holders Prior to Certain Actions. In case of any:

(a) action by the Company or one of its Subsidiaries that would require an adjustment in the Conversion Rate pursuant toSection 14.04 orSection 14.13;

(b) Merger Event; or

120

then, in each case (unless notice of such event is otherwise required pursuant to another provision of this Indenture), the Company shall cause to be filed with the Trustee and the Conversion Agent (if other than the Trustee) and to be delivered to each Holder, as promptly as possible but in any event at least 20 days prior to the applicable date hereinafter specified, a notice stating (i) the date on which a record is to be taken for the purpose of such action by the Company or one of its Subsidiaries 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 or one of its Subsidiaries, or (ii) the date on which such Merger Event, dissolution, liquidation orwinding-up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such Merger Event, dissolution, liquidation orwinding-up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such action by the Company or one of its Subsidiaries, Merger Event, dissolution, liquidation orwinding-up.

Section 14.13 Stockholder Rights Plans. If the Company has a stockholder 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 stockholder 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 stockholder 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 inSection 14.04(c), subject to readjustment in the event of the expiration, termination or Optional Mandatory Conversion of such rights.

Section 14.14 Exchange in Lieu of Conversion.

(a) When a Holder surrenders its Notes for conversion, the Company may, at its election (an “Exchange Election”), direct the Conversion Agent to surrender, on or prior to the second Trading Day immediately following the Conversion Date, such Notes to one or more financial institutions designated by the Company for exchange in lieu of conversion. In order to accept any Notes surrendered for conversion, the designated financial institution(s) must agree to timely pay or deliver, as the case may be, in exchange for such Notes, cash, shares of Common Stock or a combination of cash and shares of Common Stock, at the Company’s election, that would otherwise be due upon conversion as described inSection 14.02 (the “Conversion Consideration”). If the Company makes an Exchange Election, the Company shall, by the close of business on the Trading Day following the relevant Conversion Date, notify in writing the Trustee, the Conversion Agent (if other than the Trustee) and the Holder surrendering its Notes for conversion that the Company has made the Exchange Election, and the Company shall notify the designated financial institution(s) of the relevant deadline for delivery of the consideration due upon conversion and the type of Conversion Consideration to be paid and/or delivered, as the case may be.

121

(b) Any Notes exchanged by the designated financial institution(s) shall remain outstanding, subject to the Applicable Procedures of the Depositary. If the financial institution(s) agree(s) to accept any Notes for exchange but does not timely pay and/or deliver, as the case may be, the related Conversion Consideration, or if such designated financial institution does not accept the Notes for exchange, the Company shall pay and/or deliver, as the case may be, the relevant Conversion Consideration as, and at the time, required pursuant to this Indenture as if the Company had not made the Exchange Election.

(c) The Company’s designation of any financial institution(s) to which the Notes may be submitted for exchange does not require such financial institution(s) to accept any Notes.

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 at any time, 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”) specified by the Company that is not less than 20 calendar days or more than 35 calendar days following the date of the Fundamental Change Company Notice at a repurchase price equal to 100% of the principal amount thereof,plus any 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 an Interest Record Date but on or prior to the Interest Payment Date to which such Interest Record Date relates, in which case the Company shall instead pay the full amount of any accrued and unpaid interest to Holders of record as of such Interest Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of Notes to be repurchased pursuant to thisArticle 15.

(b) Repurchases of Notes under thisSection 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 asExhibit 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, on or before the close of business on the 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 Applicable Procedures of the Depositary, in each case, such delivery being a condition to receipt by the Holder of the Fundamental Change Repurchase Price therefor.

122

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

(iii) in the case of Physical Notes, the certificate numbers of the Notes to be delivered for repurchase;

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

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

provided,however, that if the Notes are Global Notes, the Fundamental Change Repurchase Notice must comply with the Applicable Procedures of the Depositary.

Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change Repurchase Notice contemplated by thisSection 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 Business Day immediately preceding the Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance withSection 15.03.

The Paying Agent (if other than the Company) shall promptly notify the Company 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 notice (the “Fundamental Change Company Notice”) of the occurrence of the effective date of the Fundamental Change and of the repurchase right at the option of the Holders arising as a result thereof. 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:

(ii) the date of the Fundamental Change;

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

(iv) the Fundamental Change Repurchase Price;

123

(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 this 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 thisSection 15.02.

At the Company’s request made at least five Business Days prior to the date on which notice is to be sent (or such shorter period as the Trustee may agree), 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.

Simultaneously with providing such notice, the Company shall publish a notice containing the information set forth in the Fundamental Change Company Notice in a newspaper of general circulation in The City of New York or publish such information on the Company’s website or through such other public medium as the Company may use at such time.

(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 Applicable 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 anything to the contrary in thisArticle 15, the Company shall not be required to repurchase or make an offer to repurchase the 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 Indenture, 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 Indenture.

(f) To the extent that, as a result of a change in law occurring after the first date on which the Notes are issued, the provisions of any applicable securities laws or regulations conflict

124

with the provisions of this Indenture relating to the Company’s obligations to purchase the Notes upon a Fundamental Change, 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 Indenture by virtue of such conflict.

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 in accordance with thisSection 15.03 at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date, specifying:

(c) 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 Applicable 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 inSection 4.04) on or prior to 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date an amount of money, in immediately available funds, 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 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 inSection 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 bySection 15.02 by mailing checks for the amount payable to the Holders of such Notes entitled thereto as they shall appear in the Note Register;provided,however, that payments to the Depositary shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. The Trustee shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Fundamental Change Repurchase Price.

(b) If by 11:00 a.m. New York City time, on the Fundamental Change Repurchase Date, the Paying Agent 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

125

withdrawn, (i) such Notes will cease to be outstanding, (ii) interest, if and to the extent any interest is accruing or payable on such date, 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 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 applicable, accrued and unpaid interest).

(c) Upon surrender of a Note that is to be repurchased in part pursuant toSection 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 Rule13e-4, Rule14e-1 and any other tender offer rules under the Exchange Act that may then be applicable;

(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 thisArticle 15 to be exercised in the time and in the manner specified in thisArticle 15.

ARTICLE 16

OPTIONAL MANDATORY CONVERSION

Section 16.01 Optional Mandatory Conversion. The Company may elect at its option to cause all or a portion subject to the Applicable Procedures of the Notes to be mandatorily converted (an “Optional Mandatory Conversion”) at any time following the Issue Date and prior to the close of business on the Business Day immediately preceding the Maturity Date if (i) the Last Reported Sale Price of the Common Stock has been at least 130% 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 on, and including, the Trading Day immediately preceding the date on which the Company provides the Mandatory Conversion Notice in accordance withSection 16.02 (any such period, a “Mandatory Conversion Trigger Period”), (ii) the Equity Payment Conditions (other than clause (iii) of the definition thereof) have been met, (iii) the shares of Common Stock issuable upon any conversion of the Notes would, at the time of such Mandatory Conversion Notice, be unrestricted shares that are freely tradable by Holders other than the Company’s Affiliates (or Holders that were not the Company’s Affiliates at any time during the three immediately preceding months) pursuant to an exemption under Rule 144, or pursuant to an effective registration statement that has been declared effective under the Securities Act, (iv) the Common Stock is listed on The New York Stock Exchange, The Nasdaq Global Market or The Nasdaq Global Select Market (or any of their respective successors) (each, an “Eligible Market”) and has not been suspended from trading on the applicable Eligible Market (other than suspensions of not more than two Trading Days and occurring before the applicable date of determination due to business announcements by the Company), (v) the delisting or

126

suspension of the Common Stock is not pending and has not been threatened in writing by the applicable Eligible Market, and the Company is not then in violation of the then effective minimum listing maintenance requirements of such Eligible Market, (vi) all shares of Common Stock issuable upon Optional Mandatory Conversion may be issued in full without violating the listing rules of the Eligible Market on which the Common Stock is then listed or trading, and (vii) the Company has not defaulted on its obligation to convert any Note before the date the Company sends the Mandatory Conversion Notice, and no Event of Default has occurred and is continuing.

Section 16.02 Notice of Optional Mandatory Conversion; Selection of Notes. (a) In case the Company exercises its Optional Mandatory Conversion right to convert all or, as the case may be, any part of the Notes pursuant toSection 16.01, it shall fix a date for Optional Mandatory Conversion (each, a “Mandatory Conversion Date”) and it or, at its written request received by the Trustee not less than 45 Scheduled Trading Days prior to the Mandatory Conversion Date (or such shorter period of time as may be acceptable to the Trustee), the Trustee, in the name of and at the expense of the Company, shall deliver or cause to be delivered a notice of such Optional Mandatory Conversion (a “Mandatory Conversion Notice”) not less than 30 nor more than 45 Scheduled Trading Days prior to the Mandatory Conversion Date to the Conversion Agent (if other than the Trustee) and each Holder of Notes so to be converted as a whole or in part;provided,however, that, if the Company shall give such notice, it shall also give written notice of the Mandatory Conversion Date to the Trustee and the Conversion Agent. The Mandatory Conversion Date must be a Business Day.

If any of the conditions inSection 16.01 cease to be satisfied at any time after the Company sends a Mandatory Conversion Notice, the Company will promptly (and no later than the scheduled Mandatory Conversion Date) notify the Holders and the Trustee (and the Paying Agent, if not also the Trustee) of the same, specifying that the Optional Mandatory Conversion ceases to apply. Except as set forth in the preceding sentence, the Company’s issuance of a Mandatory Conversion Notice will be irrevocable. For the avoidance of doubt, the Company shall have no right to convert a Holder’s Notes in connection with an Optional Mandatory Conversion if such conversion would result in such Holder exceeding the Beneficial Ownership Limitations.

(b) The Mandatory Conversion Notice, if delivered 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 Mandatory Conversion Notice by mail or any defect in the Mandatory Conversion Notice to the Holder of any Note designated for Optional Mandatory Conversion as a whole or in part shall not affect the validity of the proceedings for the Optional Mandatory Conversion of any other Note.

(i) the Mandatory Conversion Date;

(ii) the aggregate principal amount of Notes to be mandatorily converted;

(iii) the Settlement Method;

(iv) the Conversion Rate and Conversion Price then in effect;

127

(v) that on and after the Mandatory Conversion Date interest on the Notes to be converted will cease to accrue;

(vi) the procedures a converting Holder must follow to convert its Notes and the Settlement Method and Specified Dollar Amount, if applicable;

(vii) the name and address of each Paying Agent and Conversion Agent and the place or places where such Notes are to be surrendered for conversion;

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

(ix) in case any Note is to be converted in part only, the portion of the principal amount thereof to be converted and on and after the Mandatory Conversion Date, upon surrender of such Note, a new Note in principal amount equal to the unconverted portion thereof shall be issued.

(d) If any Optional Mandatory Conversion involves fewer than all of the then outstanding Notes, the Company shall select the Notes to be mandatorily converted (such that the principal amount of a Holder’s Note not to be converted equals $1,000 or an integral multiple of $1,000 in excess thereof) as follows: (1) in the case of Global Notes, in accordance with Applicable Procedures; and (2) in the case of Definitive Notes, pro rata, by lot or by such other method as the Trustee shall deem fair and appropriate. To the extent any Note or portion thereof selected for Optional Mandatory Conversion is thereafter submitted for voluntary conversion pursuant toSection 14.01, the portion of such Note submitted for voluntary conversion shall be deemed (so far as may be possible) to be from the portion selected for the Optional Mandatory Conversion (with any remaining portion being voluntarily converted pursuant toSection 14.01 hereof). Notwithstanding the foregoing, to the extent that, prior to a Mandatory Conversion Date, the Holder has the right to deliver a Fundamental Change Repurchase Notice and, prior to the close of business on the third Business Day immediately preceding the Mandatory Conversion Date, the Holder validly delivers a Fundamental Change Repurchase Notice in respect of any of its Notes, any such Notes subject to such Fundamental Change Repurchase Notice shall not be subject to Optional Mandatory Conversion pursuant to such Mandatory Conversion Notice, regardless of whether such Notes have been previously selected by the Trustee for Optional Mandatory Conversion. In such event, the Trustee shall be entitled to select replacement Notes to be mandatorily converted in accordance with the same procedures set forth above.

Section 16.03 Optional Mandatory Conversion Procedures. (a) Each Holder of a Note, by such Holder’s acceptance thereof, agrees to take or cause to be taken the following actions prior to the Mandatory Conversion Date in respect of its Notes subject to an Optional Mandatory Conversion: (i) if a Definitive Note, surrender the mandatorily converted Note to the Conversion Agent (or in respect of a Global Note, take any actions required for the surrender of a beneficial interest in such Note pursuant to the Applicable Procedures), (ii) furnish such endorsements and transfer documents reasonably required by the Registrar, the Conversion Agent or the Applicable Procedures, (iii) pay any transfer or other tax, if required, (iv) if the Note is a Global Note, complete and deliver to the Depositary any required instructions pursuant to the Applicable Procedures and (v) such other actions necessary to effectuate the Optional Mandatory Conversion as may be

128

reasonably requested by the Company. In the event that a Holder does not take any of the actions set forth in the immediately preceding sentence prior to the Mandatory Conversion Date, each Holder of a Note, by such Holder’s acceptance thereof, authorizes and directs the Company to take any action on such Holder’s behalf to effectuate the Optional Mandatory Conversion and appoints the Company such Holder’sattorney-in-fact for any and all such purposes.

(b) With respect to any Notes subject to Optional Mandatory Conversion on the Mandatory Conversion Date, the Company will deliver to the Holders of such Notes the applicable Conversion Consideration in accordance withSection 14.02 andSection 14.11, as applied mutatis mutandis to such Optional Mandatory Conversion.

(c) Upon the Mandatory Conversion Date, unless the Company defaults or otherwise fails in delivering or paying the amounts due pursuant to such Optional Mandatory Conversion, interest on the Notes or portion of Notes so called for the Optional Mandatory Conversion shall cease to accrue and the Holders thereof shall have no right in respect of such Notes except the right to receive the shares of Common Stock and cash, if any, to which they are entitled pursuant to thisSection 16.03. Upon a conversion pursuant to thisSection 16.03, the Person in whose name such shares of Common Stock will be registered will become the Holder of record of such shares of Common Stock at the close of business on the Mandatory Conversion Date for such Note.

(d) For so long as the conversion of any Notes that would have been subject to Optional Mandatory Conversion but for the limitations set forth inSection 14.10 are unable to be so converted, the Company shall be entitled, by delivery of an updated Mandatory Conversion Notice (prepared and calculated as of such date) within five Business Days after receipt of a Beneficial Ownership Certificate from the applicable Holder, to cause all or a portion of such Notes (to the extent still held by such Holder or its Affiliates) to be converted pursuant to thisSection 16.03; provided that the requirement the Last Reported Sale Price of Common Stock during a Mandatory Conversion Trigger Period equals or exceeds the 130%, shall be disregarded.

(e) To the extent that a Holder’s conversion of Notes pursuant to an Optional Mandatory Conversion was limited by the Beneficial Ownership Limitations continues to hold Notes thereafter, such Holder shall, within three Business Days following the end of each fiscal quarter, commencing with the fiscal quarter in which an Optional Mandatory Conversion of Notes held by such Holder was first limited by the Beneficial Ownership Limitations, certify in writing to the Company its beneficial ownership of shares of Common Stock (the “Beneficial Ownership Certificate”). The provisions of this paragraph will not affect the rights of any Holder of Notes who fails to deliver a Beneficial Ownership Certificate as required pursuant to thisSection 16.03(e).

(f) If any of the provisions of thisSection 16.03 are inconsistent with applicable law or, in the case of Global Notes, the Applicable Procedures, at the time of such Optional Mandatory Conversion, such applicable law and Applicable Procedures shall govern.

ARTICLE 17

COLLATERAL

Section 17.01 Note Security Documents. (a) Subject toSection 7.01, none of the Collateral Agent or the Trustee nor any of their respective officers, directors, employees, attorneys or agents makes any representations as to and shall not be responsible or liable for the existence, genuineness, value, protection or condition of any of the Collateral or as to the security afforded or intended to be afforded thereby, hereby or by any of the Note Security Documents, or for the legality, sufficiency, effectiveness, validity, perfection, priority or enforceability of the Liens or any other security interests in any of the Collateral created or intended to be created by any of the Note Security Documents, whether impaired by operation of law or by reason of any action or omission to act on its part hereunder, for the validity or sufficiency of any of the Note Security Documents or any agreement or assignment contained in any thereof, for the validity of the title of the Company to the Collateral, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral or any defect or deficiency as to any such matters.

(b) If the Company or any Guarantor acquires any assets or property that are required to become Collateral pursuant to this Indenture or the Note Security Documents or any Subsidiary is required to become a Guarantor pursuant toSection 4.13, the Company or such Guarantor shall promptly (and in any event within 45 days after such acquisition or requirement to become a Guarantor commences) execute a joinder to the Security Agreement and take all steps necessary to validly perfect such Lien (to the extent required by the Note Security Documents), and the Trustee and the Collateral Agent, as applicable, are authorized and directed to execute any documentation consistent therewith.

(c) The Company and each Guarantor shall execute such further documents, financing statements, agreements and instruments, and take all commercially reasonable further actions (including the filing and recording of financing statements or amendments or continuation statements in respect thereof), that may be required under any applicable law, to ensure that the Liens of the Note Security Documents on the Collateral remain perfected (to the extent required by the Note Security Documents) with the priority required by the Note Security Documents, all at the expense of the Company and Guarantors and provide to the Collateral Agent and the Trustee, from time to time upon reasonable request, evidence reasonably satisfactory to the Collateral Agent and the Trustee as to the perfection and priority of the Liens created or intended to be created by the Note Security Documents. It being understood and agreed that the Company and Guarantors shall not be required to provide, and the Collateral Agent shall not request, any additional Liens in respect of any Excluded Property (as defined in the Security Agreement).

130

(b) Except as required or permitted by the Note Security Documents, the Holders, by accepting a Note, acknowledge that the Collateral Agent will not be obligated:

(i) to act upon directions purported to be delivered to it by any Person, except in accordance with the Note Security Documents;

(ii) to foreclose upon or otherwise enforce any Lien granted pursuant to the Note Security Documents; or

(iii) to take any other action whatsoever with regard to any or all of the Note Security Documents (including any Lien granted thereunder) or Collateral.

(c) The Collateral Agent will act pursuant to the instructions of the Holders and the Trustee with respect to the Collateral. For the avoidance of doubt, the Collateral Agent will have no discretion under this Indenture or the Note Security Documents and will not be required to make or give any determination, consent, approval, request or direction without the written direction of the Holders of a majority in aggregate principal amount of the then outstanding Notes or the Trustee, as applicable. After the occurrence of an Event of Default, the Trustee may (but will not be obligated to) direct the Collateral Agent in connection with any action required or permitted by this Indenture.

(d) None of the Collateral Agent or any of its Affiliates will be liable for any action taken or omitted to be taken by any of them under or in connection with this Indenture or the transactions contemplated hereby (except for its own gross negligence or willful misconduct as determined by a final order of a court of competent jurisdiction).

(e) Other than in connection with a release of Collateral permitted underSection 17.04 or as may be required bySection 9.02, in each case that the Collateral Agent may or is required hereunder to take any action (an “Action”), including without limitation to make any determination, to give consents, to exercise rights, powers or remedies, to release or sell Collateral or otherwise to act hereunder, the Collateral Agent may seek direction from the Holders of a majority in aggregate principal amount of the then outstanding Notes.

[FORM OF REVERSE OF NOTE]

ACORDA THERAPEUTICS, INC.

6.00% Convertible Senior Secured Note due 2024

This Note is one of a duly authorized issue of Notes of the Company, designated as its 6.00% Convertible Senior Secured Notes due 2024 (the “Notes”), limited to the aggregate principal amount of $210,000,000 all issued or to be issued under and pursuant to an Indenture dated as of December 23, 2019 (the “Indenture”), between the Company and WILMINGTON TRUST, NATIONAL ASSOCIATION, as trustee (in such capacity, the “Trustee”) and as collateral agent (in such capacity, the “Collateral Agent”), 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 Collateral Agent, 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.

To guarantee the due and punctual payment of the principal and interest (including post-filing or post-petition interest) on the Notes and all other amounts payable by the Company under the Indenture, the Notes and the other Transaction Documents when and as the same shall be due and payable, whether at maturity, by acceleration or otherwise, according to the terms of the Notes and the Indenture, the Guarantors will unconditionally guarantee (and future guarantors, jointly and severally with the Guarantors, will fully and unconditionally Guarantee) such obligations on a senior secured basis pursuant to the terms of the Indenture.

The Notes and the Guarantor’s Guarantees of the Notes will be secured by the Collateral on the terms and subject to the conditions set forth in the Indenture and the Note Security Documents. The Collateral Agent will hold the Collateral for the benefit of the Holders pursuant to the Note Security Documents. Each Holder, by accepting this Note, consents and agrees to the terms of the Note Security Documents (including the provisions providing for the foreclosure and release of Collateral), as the same may be in effect or may be amended from time to time in accordance with their terms and the Indenture and authorizes and directs the Collateral Agent to enter into the Note Security Documents and to perform its obligations and exercise its rights thereunder in accordance therewith.

In case certain Events of Default shall have occurred and be continuing, the principal of, and any 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 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.

A-5

The Indenture contains provisions permitting the Company, the Trustee and the Collateral Agent, 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 or supplements and amendments modifying the terms of the Indenture, the Notes and the other Transaction Documents 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.

Each Holder shall have the right to receive payment or delivery, as the case may be, of (x) the principal (including the Fundamental Change Repurchase Price, if applicable) of, (y) accrued and unpaid interest, if any, on, and (z) 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 minimum denominations of $1,000 principal amount and integral multiples of $1,000 in excess 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 not be redeemable at the Company’s option and no sinking fund is provided for the Notes. The Company will have the right to cause the automatic conversion of all Notes then outstanding in the manner, and subject to the terms, set forth inArticle 16 of the Indenture.

Upon the occurrence of a Fundamental Change, 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, during certain periods and upon the occurrence of certain conditions specified in the Indenture, prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, to convert any Notes or portion thereof that is $1,000 or an integral multiple thereof, into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture.
