Section 2.01.      Designation and Amount. The Notes shall be designated as the “4.25%/5.25% Exchangeable Senior Notes due 2022.” The aggregate Initial Principal Amount of Notes that may be authenticated and delivered under this Indenture is initially limited to $36,242,500, subject to ‎ Section 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 in Exhibit 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 Issuer, the Guarantors 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 or endorsements as any Officer executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of 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 Initial Principal Amount of the outstanding Notes as shall be specified therein and shall provide that it shall represent the aggregate Initial Principal Amount of outstanding Notes from time to time endorsed thereon and that the aggregate Initial Principal Amount of outstanding Notes represented thereby may from time to time be increased or reduced to reflect repurchases, cancellations, conversions, transfers, exchanges or issuances of additional Notes pursuant to ‎Section

2.10 (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 aggregate Initial Principal 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 written instructions given by the Holder of such Notes in accordance with this Indenture. Payment of principal (including the Fundamental Change Repurchase Price and Redemption Price, if applicable) of, and accrued interest that has not been paid or capitalized 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; Payments of Principal, Interest and Defaulted Amounts.

(a)             The Notes shall be issuable in registered form without coupons in minimum denominations of $1,000 Initial Principal Amount and integral multiples of $1.00 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. Accrued interest on the Notes, including any Additional Interest, shall be computed on the basis of a 360-day year composed of twelve 30-day months or, in the case of a partial month, the number of days elapsed over a 30-day month. The Issuer shall 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.

(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 Regular Record Date with respect to any Interest Payment Date shall be entitled to receive the interest payable in cash on such Interest Payment Date. The Capitalized Principal Amount of any Note (x) in the case of any Physical Note, shall be payable at the office or agency of the Issuer maintained by the Issuer for such purposes in the continental United States of America, which shall initially be the Corporate Trust Office 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. The Issuer through the Paying Agent, shall pay cash interest (i) on any Physical Notes (A) to Holders holding Physical Notes having an aggregate Initial Principal Amount of $5,000,000 or less, by check mailed to the Holders of these Notes at their address as it appears in the Note Register and (B) to Holders holding Physical Notes having an aggregate Initial Principal Amount of more than $5,000,000, either by check mailed to each such Holder or, upon application by such a Holder to the Note Registrar not later than the relevant Regular Record Date, by wire transfer in immediately available funds to that Holder’s account within the United States, which application shall remain in effect until the Holder notifies, in writing, the Note Registrar to the contrary or (ii) on any Global Note by wire transfer of immediately available funds to the account of the Depositary or its nominee.

(c)             Any Defaulted Amounts shall forthwith cease to be payable to the Holder on the relevant payment date but shall accrue interest per annum at the rate borne by the Notes, subject to the enforceability thereof under applicable law, from, and including,

such relevant payment date, and such Defaulted Amounts together with such interest thereon shall be paid by the Issuer, at its election in each case, as provided in clause (i) or (ii) below:

(i)                 The Issuer 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 Issuer shall notify the Trustee in writing of the amount of the Defaulted Amounts proposed to be paid on each Note, the date of the proposed payment and the special record date, and the Issuer shall deposit with the Trustee an amount of money equal to the aggregate amount to be paid in respect of such Defaulted Amounts 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. The Issuer shall fix a special record date for the payment of such Defaulted Amounts which shall be not more than 15 calendar days and not less than 10 calendar days prior to the date of the proposed payment. The Issuer shall send notice of the proposed payment of such Defaulted Amounts and the special record date therefor to each Holder not less than 10 calendar days prior to such special record date. The Trustee shall send such notice at the request of the Issuer contained in an Officers’ Certificate; provided the Issuer shall provide the Trustee with the form of such notice at least five Business Days prior (or such shorter period as the Trustee may agree) to the date such notice is to be provided. 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.

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

(iii)             The Trustee shall not at any time be under any duty or responsibility to any Holder to determine the Defaulted Amounts, or with respect to the nature, extent, or calculation of the amount of the Defaulted Amounts owed, or with respect to the method employed in such calculation of the Defaulted Amounts.

(d)               The Notes shall mature on July 15, 2022, unless earlier exchanged or redeemed in accordance with the provisions hereof. On the Maturity Date, each Holder shall be entitled to receive the Capitalized Principal Amount of its Notes as of the Maturity Date, including any accrued interest that has not been paid or capitalized to, but

excluding, the Maturity Date. With respect to Global Notes, principal and interest shall be paid to the Depositary in immediately available funds. With respect to Physical Notes, principal and interest shall be payable at the Issuer’ office or agency in the United States, which initially will be the Corporate Trust Office.

(e)                The Issuer may, at its option, elect to pay interest on the Notes on any Interest Payment Date (i) by paying an amount in cash on such Interest Payment Date equal to the interest accrued from, and including, the immediately preceding Interest Payment Date (or if there is no immediately preceding Interest Payment Date, from, and including, the Issue Date) on the Capitalized Principal Amount as of the immediately preceding Interest Payment Date (or if there is no immediately preceding Interest Payment Date, interest on the Initial Principal Amount), calculated at the rate of 4.25% per annum (plus Additional Interest, if any) (the “ All Cash Method ”) or (ii) by paying an amount in cash on such Interest Payment Date equal to the interest accrued from, and including, the immediately preceding Interest Payment Date (or if there is no immediately preceding Interest Payment Date, from, and including, the Issue Date) on the Capitalized Principal Amount as of the immediately preceding Interest Payment Date (or if there is no immediately preceding Interest Payment Date, interest on the Initial Principal Amount), calculated at the rate of 3.00% per annum and increasing the Capitalized Principal Amount of the Notes by the Capitalization Amount for such Interest Payment Date (the “ Cash/Capitalization Method ”); provided, that , on any Interest Payment Date on which the Issuer pays interest using the Cash/Capitalization Method, the Capitalized Principal Amount shall be rounded up to the nearest $1.00. The Issuer shall elect the method of paying interest on an Interest Payment Date by delivering a notice to the Trustee and the Holders prior to the Regular Record Date immediately preceding such Interest Payment Date identifying the method selected, the amount of cash interest to be paid and the Capitalization Amount and new Capitalized Principal Amount. In the absence of such an election with respect to an Interest Payment Date, the Issuer shall be deemed to have elected the All Cash Method. Notwithstanding any other provision of this Indenture, the Issuer shall be deemed to have elected the All Cash Method with respect to interest payable on the Maturity Date, Repayment Triggering Event Redemption Date, or on any Redemption Date.

Section 2.04.      Execution, Authentication and Delivery of Notes. The Notes shall be signed in the name and on behalf of the Issuer by the manual or facsimile signature of any Officer.

The Trustee shall authenticate (i) Initial Notes for original issue on the Issue Date in an aggregate Initial Principal Amount of $36,242,500 and (ii) subject to compliance with the provisions of this Indenture, one or more series of Notes (“ Additional Notes ”), for original issue after the Issue Date (such Notes to be substantially in the form of Exhibit A) in an unlimited aggregate principal amount, in each case upon written order of the Issuer which shall certify that such issuance is in compliance with the conditions precedent of this Indenture, together with an enforceability opinion that contains customary exceptions. In addition, each such order shall specify the amount of Notes to be authenticated, the date on which the Notes are to be authenticated, whether the securities are to be Initial Notes or Additional Notes and the aggregate Initial Principal Amount of Notes outstanding on the date of authentication, and shall further specify the amount of such Notes to be issued as Global Notes. Such Notes shall initially be in the

form of one or more Global Notes, which (i) shall represent, and shall be denominated in an amount equal to the aggregate Initial Principal Amount of, the Notes to be issued, (ii) shall be registered in the name of the Depositary or its nominee and (iii) shall be delivered by the Trustee to the Depositary or held by the Trustee pursuant to the Depositary’s instruction. All Notes issued under this Indenture shall vote and consent together on all matters as one class and no series of Notes shall have the right to vote or consent as a separate class on any matter.

Only such Notes as shall bear thereon a certificate of authentication substantially in the form set forth on the Form of Note attached as Exhibit A hereto, executed manually by an authorized signatory of the Trustee (or an authenticating agent appointed by the Trustee as provided by ‎Section 17.10), 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 Issuer shall be conclusive evidence that the Note so authenticated has been duly authenticated and delivered hereunder and that the Holder is entitled to the benefits of this Indenture.

In case any Officer of the Issuer who shall have signed any of the Notes shall cease to be such Officer before the Notes so signed shall have been authenticated and delivered by the Trustee, or disposed of by the Issuer, such Notes nevertheless may be authenticated and delivered or disposed of as though the person who signed such Notes had not ceased to be such Officer of the Issuer; and any Note may be signed on behalf of the Issuer by such persons as, at the actual date of the execution of such Note, shall be the Officers of the Issuer, 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 Issuer 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 Issuer designated pursuant to ‎ Section 4.02, the “ Note Register ”) in which, subject to such reasonable regulations as it may prescribe, the Issuer shall provide for the registration of Notes and of transfers of Notes. 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 Issuer may appoint one or more co-Note Registrars in accordance with ‎ Section 4.02.

Upon surrender for registration of transfer of any Note to the Note Registrar or any co-Note Registrar, and satisfaction of the requirements for such transfer set forth in this ‎Section 2.05, the Issuer shall execute, and the Trustee, upon receipt of any items required to be delivered hereunder, 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 Initial 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 Initial Principal Amount, upon surrender of the Notes to be exchanged at

any such office or agency maintained by the Issuer pursuant to ‎Section 4.02. Whenever any Notes are so surrendered for exchange, the Issuer shall execute, and the Trustee shall authenticate and deliver, the Notes 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 or repurchase shall (if so required by the Issuer, the Trustee, the Note Registrar or any co-Note Registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Issuer and the Trustee and duly executed, by the Holder thereof or its attorney-in-fact duly authorized in writing.

No service charge shall be imposed on the Holder by the Issuer, the Trustee, the Note Registrar, any co-Note Registrar or the Paying Agent for any exchange or registration of transfer of Notes, but the Issuer 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 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 Issuer, the Trustee, the Note Registrar or any co-Note Registrar shall be required to exchange or register a transfer of (i) any Notes surrendered for exchange or, if a portion of any Note is surrendered for exchange, such portion thereof surrendered for exchange or (ii) any Notes, or a portion of any Note, surrendered for repurchase (and not withdrawn) in accordance with ‎Article 15.

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

(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 of ‎ Section 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. Each Global Note shall bear the legend required on a Global Note set forth in Exhibit A hereto. The transfer and exchange of beneficial interests in a Global Note that does not involve the issuance of a Physical Note shall be effected through the Depositary in accordance with this Indenture (including the restrictions on transfer set forth herein) and the procedures of the Depositary therefor.

(c)               Every Note that bears or is required under this ‎ Section 2.05(c) to bear the legend set forth in this ‎ Section 2.05(c) (together with any Common Stock issued upon exchange of the Notes that is required to bear the legend set forth in ‎ Section 2.05(d), collectively, the “ Restricted Securities ”) shall be subject to the restrictions on transfer set forth in this ‎ Section 2.05(c) (including those contained in the legend set forth below), unless such restrictions on transfer shall be eliminated or otherwise waived by written consent of the Issuer, 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 this ‎ Section 2.05(c) and Section ‎ 2.05(d), the term “ transfer ” encompasses any sale, pledge, transfer or other disposition whatsoever of any Restricted Security.

(i)                 Until 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 other 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 exchange thereof, which shall bear the legend set forth in ‎ Section 2.05(d), if applicable) shall bear a legend in substantially the following form (unless such Notes have been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and 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 Issuer in writing, with notice thereof to the Trustee) (such legend, the “ Restricted Notes Legend ”):

THE SALE OF THIS NOTE HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “ SECURITIES ACT ”), AND, ACCORDINGLY, PRIOR TO THE RESALE RESTRICTION TERMINATION DATE (AS DEFINED BELOW), THIS NOTE AND ANY SHARES OF COMMON STOCK ISSUABLE UPON exchange OF THIS NOTE MAY NOT BE OFFERED, RESOLD OR OTHERWISE TRANSFERRED, EXCEPT:

(A)             TO PERNIX IRELAND PAIN LIMITED (THE “ ISSUER ”) OR ANY PARENT OR SUBSIDIARY THEREOF;

(B)              PURSUANT TO, AND IN ACCORDANCE WITH, A REGISTRATION STATEMENT THAT IS EFFECTIVE UNDER THE SECURITIES ACT AT THE TIME OF SUCH TRANSFER;

(C)              TO A PERSON THAT YOU REASONABLY BELIEVE TO BE A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT OR TO A PERSON THAT YOU REASONABLY BELIEVE TO BE AN INSTITUTIONAL ACCREDITED INVESTOR AS DEFINED IN RULE 501(A)(1), (2), (3) OR (7) OF REGULATION D UNDER THE SECURITIES ACT; OR

(D)             UNDER ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT (INCLUDING, IF AVAILABLE, THE EXEMPTION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT).

THE “ RESALE RESTRICTION TERMINATION DATE ” MEANS 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 PERMITTED BY RULE 144 OR ANY SUCCESSOR PROVISION THERETO; AND (2) SUCH OTHER DATE AS MAY BE REQUIRED BY APPLICABLE LAW.

WITH RESPECT TO ANY TRANSFER PURSUANT TO THE FOREGOING CLAUSE ‎(D), PRIOR TO THE RESALE RESTRICTION TERMINATION DATE, THE ISSUER AND THE TRUSTEE RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS THEY MAY REASONABLY REQUIRE AND MAY RELY UPON TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

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.

(ii)               Notwithstanding clause ‎ (i) above, each Affiliate Note shall bear a legend in substantially the following form, unless: (A) such Note has been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer, (B) such Note has been sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act or (C) as is otherwise agreed by the Issuer, with notice thereof to the Trustee:

THE SALE OF THIS NOTE HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “ SECURITIES ACT ”), AND THIS NOTE AND ANY SHARES OF COMMON STOCK ISSUABLE UPON exchange OF THIS NOTE, MAY NOT BE OFFERED, RESOLD OR OTHERWISE TRANSFERRED, EXCEPT:

(A)             TO PERNIX IRELAND PAIN LIMITED (THE “ ISSUER ”) OR ANY PARENT OR SUBSIDIARY THEREOF;

(B)              PURSUANT TO, AND IN ACCORDANCE WITH, A REGISTRATION STATEMENT THAT IS EFFECTIVE UNDER THE SECURITIES ACT AT THE TIME OF SUCH TRANSFER; OR

(C)              SUCH TRANSFERS ALLOWED UNDER THE SECURITIES ACT TO SUCH TRANSFEREES THAT AGREE IN WRITING TO THE TRANSFER RESTRICTIONS SET FORTH HEREIN.

WITH RESPECT TO ANY TRANSFER PURSUANT TO THE FOREGOING CLAUSE ‎(C), THE ISSUER AND THE TRUSTEE RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS THEY MAY REASONABLY REQUIRE AND MAY RELY UPON TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

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, and in accordance with, 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 this ‎Section 2.05, be exchanged for a new Note or Notes, of like tenor and aggregate Initial Principal Amount, which shall not bear the restrictive legend required by this ‎Section 2.05(c) and shall not be assigned a restricted CUSIP number, unless such Note is acquired by an Affiliate of the Issuer. The Issuer shall be entitled to 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 this ‎Section 2.05(c) and shall not be assigned a restricted CUSIP number. The Issuer 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 exchange of the Notes has been declared effective under the Securities Act. The Issuer shall complete any exchange process for the removal of a restrictive legend required by this ‎Section 2.05(c) in accordance with the applicable procedures of the Depositary.

Notwithstanding any other provisions of this Indenture (other than the provisions set forth in this ‎Section 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 Issuer 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. The Trustee shall have no liability or responsibility for the action or inaction of the Depositary or any other clearing agency.

If (i) the Depositary notifies the Issuer at any time that the Depositary is unwilling or unable to continue as depositary for the Global Notes and a successor depositary is not appointed within 90 calendar days, (ii) the Depositary ceases to be registered as a clearing agency under the Exchange Act and a successor depositary is not appointed within 90 calendar days or (iii) an Event of Default with respect to the Notes has occurred and is continuing and a beneficial owner of any Note requests that its beneficial interest therein be exchanged for a Physical Note, the Issuer shall execute, and the Trustee, upon receipt of an Officers’ Certificate, an Opinion of Counsel and an Issuer 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 an Initial Principal Amount equal to the Initial 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 Initial Principal Amount equal to the aggregate Initial Principal Amount of such Global Notes in exchange for such Global Notes, and upon delivery of the Global Notes to the Trustee such Global Notes shall be canceled.

Physical Notes issued in exchange for all or a part of the Global Note pursuant to this ‎Section 2.05(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, shall instruct the Trustee in writing. 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 exchanged, canceled, repurchased or transferred, such Global Note shall be, upon receipt thereof and upon receipt of an Issuer Order directing the Trustee to cancel the Global Notes, 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, exchanged, canceled, repurchased 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 Initial Principal Amount of such Global Note shall, in accordance with the standing procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced or increased, as the case may be, and an endorsement shall be made on such Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction or increase.

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

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

owners of interests 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.

The Holder of an Affiliate Note may exchange such Note for a beneficial interest in another Global Note or transfer such Affiliate Note to a Person who takes delivery thereof in the form of a beneficial interest in another Global Note only if the transfer is completed in accordance with the applicable procedures of the Depositary and the Trustee receives: (A) a certificate from such Holder, certifying as follows (in each case, which certificate shall be approved by the Issuer): (1) in the case of a proposed exchange, such Holder (x) is not an Affiliate of the Issuer and has not been an Affiliate of the Issuer during the three immediately preceding months, and (y) one year has elapsed since the date the Affiliate Notes were acquired from the Issuer or from an Affiliate of the Issuer, or (2) in the case of a proposed transfer, such representations as are necessary to establish that such Holder’s proposed transfer of the Affiliate Note satisfies all applicable requirements set forth in Rule 144 under the Securities Act or that such Holder’s proposed transfer of Affiliate Notes was effected pursuant to an effective registration statement covering the resale of such Affiliate Note, (B) if the Issuer or the Trustee so requests, an Opinion of Counsel in form and substance reasonably satisfactory to the Issuer and the Trustee to the effect that such proposed exchange or transfer is in compliance with the safe harbor contained in Rule 144 under the Securities Act and that the restrictions on transfer contained on such Affiliate Note are no longer required in order to maintain compliance with such safe harbor or that such transfer was effected pursuant to an effective registration statement covering the sale of such Affiliate Note, and (C) written instructions directing the Trustee to make, or to direct the Note Registrar to make, an adjustment to its books and records with respect to such Global Note to reflect an increase in the aggregate Initial Principal Amount of the Notes represented by the Global Note, such instructions to contain information regarding the Depositary account to be credited with such increase. Upon such transfer, then the Trustee shall cancel the Affiliate Note in accordance with ‎Section 2.08 of this Indenture, and cause, or direct the Note Registrar to cause, in accordance with the standing instructions and procedures existing between the Depositary and the Note Registrar, the aggregate Initial Principal Amount of the Affiliate Note to be exchanged, and shall credit or cause to be credited to the account of the Person specified in such instructions a beneficial interest in the applicable Global Note equal to the Initial Principal Amount of the Affiliate Note so cancelled.

(d)                Legends on the Common Stock:

(i)                 Until the Resale Restriction Termination Date, any stock certificate representing Common Stock issued upon exchange of a Note shall bear a legend in substantially the following form (unless such Common Stock has been transferred pursuant to, and in accordance with, 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 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 exchange of a Note that has transferred pursuant to, and in accordance with, 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 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 Issuer with written notice thereof to the Trustee and any transfer agent for the Common Stock) (such legend, the “ Restricted Stock Legend ”):

THE SALE OF THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “ SECURITIES ACT ”), AND ACCORDINGLY, PRIOR TO THE RESALE RESTRICTION TERMINATION DATE (AS DEFINED BELOW), THIS SECURITY MAY NOT BE OFFERED, RESOLD, OR OTHERWISE TRANSFERRED, EXCEPT:

(D)             UNDER ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT (INCLUDING, IF AVAILABLE, THE EXEMPTION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT).

THE “ RESALE RESTRICTION TERMINATION DATE ” MEANS THE LATER OF: (1) THE DATE THAT IS ONE YEAR AFTER THE LAST DATE OF ORIGINAL ISSUANCE OF THE ISSUER’S 4.25%/5.25% EXCHANGEABLE SENIOR Notes due 2022 OR SUCH SHORTER PERIOD OF TIME PERMITTED BY RULE 144 OR ANY SUCCESSOR PROVISION THERETO; AND (2) SUCH OTHER DATE AS MAY BE REQUIRED BY APPLICABLE LAW.

WITH RESPECT TO ANY TRANSFER PURSUANT TO THE FOREGOING CLAUSE ‎(D), PRIOR TO THE RESALE RESTRICTION TERMINATION DATE, THE ISSUER AND THE ISSUER’S TRANSFER AGENT RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS THEY MAY REASONABLY REQUIRE AND MAY

RELY UPON TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

THE SALE OF THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “ SECURITIES ACT ”), AND ACCORDINGLY THIS SECURITY MAY NOT BE OFFERED, RESOLD OR OTHERWISE TRANSFERRED, EXCEPT:

(A)             TO PERNIX IRELAND PAIN LIMITED (THE “ ISSUER ”) OR ANY PARENT OR SUBSIDIARY THEREOF,

(B)              PURSUANT TO, AND IN ACCORDANCE WITH, A REGISTRATION STATEMENT THAT IS EFFECTIVE UNDER THE SECURITIES ACT AT THE TIME OF SUCH TRANSFER OR

(C)              SUCH TRANSFERS ALLOWED UNDER THE SECURITIES ACT TO SUCH TRANSFEREES THAT AGREE IN WRITING TO THE TRANSFER RESTRICTIONS SET FORTH HEREIN.

WITH RESPECT TO ANY TRANSFER PURSUANT TO THE FOREGOING CLAUSE ‎(C), PRIOR TO THE RESALE RESTRICTION TERMINATION DATE, THE Issuer AND THE Issuer ’S TRANSFER AGENT RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS THEY MAY REASONABLY REQUIRE AND MAY RELY UPON TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

(iii)             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, and in accordance with, 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 the certificates representing such shares of Common Stock for exchange in accordance with the procedures of the transfer agent for the Common Stock, be exchanged for a new certificate or certificates for a like aggregate number of shares of Common Stock, which shall not bear the restrictive legend required by this ‎ Section 2.05(d), unless such shares are held by an Affiliate of the Issuer.

(e)                Any Note or Common Stock issued upon the exchange of a Note that is repurchased or owned by any Affiliate of the Issuer (or any Person who was an Affiliate of the Issuer at any time during the three months preceding) may not be resold by such Affiliate (or such Person, as the case may be) unless registered under the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities Act in a transaction that results in such Note or Common Stock, as the case may be, no longer being a “restricted security” (as defined under Rule 144). The Issuer shall cause any Note that is repurchased or owned by it to be surrendered to the Trustee for cancellation in accordance with ‎ Section 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 Issuer in its discretion may execute, and upon receipt of an Issuer Order 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 Issuer, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless 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 Issuer, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

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 Issuer and, if applicable, such authenticating agent may require. No service charge shall be imposed on the Holder by the Issuer, the Trustee, the Note Registrar, any co-Note Registrar or the Paying Agent upon the issuance of any substitute Note, but the Issuer 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 exchanged in accordance with ‎Article 14 shall become mutilated or be destroyed, lost or stolen, the Issuer may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the payment of or exchange or authorize the exchange 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 exchange shall furnish to the Issuer, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, evidence satisfactory to the Issuer, the Trustee and, if applicable, any Paying Agent or Exchange Agent evidence of their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

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

Section 2.07.      Temporary Notes. Pending the preparation of Physical Notes, the Issuer may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon receipt of an Issuer Order, 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 Issuer. Every such temporary Note shall be executed by the Issuer and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Physical Notes. Without unreasonable delay, the Issuer 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 Issuer pursuant to ‎ Section 4.02 and the Trustee or such authenticating agent shall, upon receipt of an Issuer Order, authenticate and deliver in exchange for such temporary Notes an equal aggregate Initial Principal Amount of Physical Notes. Such exchange shall be made by the Issuer at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Physical Notes authenticated and delivered hereunder.

Section 2.08.      Cancellation of Notes Paid, Exchanged, Etc. The Issuer shall cause all Notes surrendered for the purpose of payment, repurchase, registration of transfer or exchange, if surrendered to any Person other than the Trustee (including any of the Issuer’s agents, Subsidiaries or Affiliates), to be surrendered to the Trustee for cancellation. All Notes delivered to the Trustee shall be canceled promptly by it in

accordance with its customary procedures, and, except for Notes surrendered for registration of transfer or exchange, no Notes shall be authenticated in exchange thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of canceled Notes in accordance with its customary procedures and, after such cancellation, shall deliver a certificate of such cancellation to the Issuer, at the Issuer’s written request in an Issuer Order.

Section 2.09.      CUSIP Numbers. The Issuer in issuing the Notes may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in 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 Issuer shall promptly notify the Trustee in writing of any change in the “CUSIP” numbers.

Section 2.10.      Additional Notes; Repurchases. The Issuer may, with the consent of the Initial Holders (or, if the Initial Holders are no longer Holders pursuant to this Indenture, the Required Holders), issue Additional Notes hereunder with the same terms as the Notes initially issued hereunder (except for any differences in issue date, issue price and interest accrued, if any) in an unlimited amount; provided, that if any such additional Notes are not fungible with the Notes initially issued hereunder for U.S. federal income tax and securities law purposes, such additional Notes shall have a separate CUSIP number. Prior to the issuance of any such additional Notes, the Issuer shall deliver to the Trustee an Issuer Order, an Officers’ Certificate and an Opinion of Counsel, such Officers’ Certificate and Opinion of Counsel to cover, in addition to those required by ‎ Section 17.05, that the additional Notes have been duly authorized by the Issuer and are enforceable against the Issuer in accordance with their terms, subject to customary exceptions, including for bankruptcy, insolvency, fraudulent transfer, reorganization, examinership, moratorium and other similar laws of general application affecting the rights and remedies of creditors and to general principles of equity (including, without limitation, concepts of materiality, reasonableness, good faith, fair dealing and unconscionability), regardless of whether considered in a proceeding in equity or law, and such other items as the Trustee may reasonably request. In addition, the Issuer may, to the extent permitted by law, and directly or indirectly (regardless of whether such Notes are surrendered to the Issuer), repurchase Notes in the open market or otherwise, whether by Holdings 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 Issuer shall cause any Notes so repurchased (other than Notes repurchased pursuant to cash-settled swaps or other derivatives) to be surrendered to the Trustee for cancellation in accordance with ‎ Section 2.08, and such Notes shall no longer be considered outstanding hereunder upon their repurchase. The Initial Notes issued on the Issue Date and any Additional Notes will be treated as a single class for all purposes under this Indenture.

Article 3
Satisfaction and Discharge

Section 3.01.      Satisfaction and Discharge. This Indenture and the Notes shall upon request of the Issuer contained in an Officers’ Certificate cease to be of further effect, and the Trustee, at the expense of the Issuer, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture and the Notes, and each Guarantor’s obligations under its Note Guarantee, will terminate if when (a) (i) all outstanding Notes theretofore authenticated and delivered (other than (x) Notes which have been destroyed, lost or stolen and which have been replaced, paid or exchanged as provided in ‎ Section 2.06 and (y) Notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Issuer and thereafter repaid to the Issuer or discharged from such trust, as provided in ‎ Section 4.04(d)) have been delivered to the Trustee for cancellation; or (ii) the Issuer and/or Holdings (as applicable) have deposited with the Trustee or delivered to Holders, as applicable, after the Notes have become due and payable, whether on the Maturity Date, any redemption date, any Fundamental Change Repurchase Date, upon exchange or otherwise, cash or, solely to satisfy the Exchange Obligation, cash and/or shares of Common Stock sufficient to pay all of the outstanding Notes or satisfy all outstanding exchanges, as the case may be, and pay all other sums due and payable under this Indenture by the Issuer (for the avoidance of doubt, Holdings will deliver any shares of Common Stock to be paid with respect to satisfying outstanding exchanges directly to the holders); and (b) the Issuer has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Issuer to the Trustee under ‎ Section 7.06 shall survive.

The Issuer will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. The terms “ Paying Agent ” and “ Exchange Agent ” include any such additional or other offices or agencies, as applicable.

(a) If, at any time, Holdings is not subject to Section 13 or 15(d) of the Exchange Act, the Issuer shall (with the cooperation of Holdings, where required), so long as any of the Notes or any shares of Common Stock issuable upon exchange thereof shall, at such time, constitute “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, upon the written request of any Holder, beneficial owner or prospective purchaser of Notes or any shares of Common Stock issuable upon the exchange of the Notes, promptly furnish such Holder, beneficial owner or prospective purchaser the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the resale of the Notes or such shares of Common Stock pursuant to Rule 144A, as such rule may be amended from time to time. The Issuer shall (and with the

cooperation of Holdings, where required) take such further action as any Holder or beneficial owner of the Notes or any shares of Common Stock issuable upon exchange of the Notes may reasonably request to the extent from time to time required to enable such Holder or beneficial owner to sell the Notes or any shares of Common Stock issuable upon exchange of the Notes in accordance with Rule 144A, as such rule may be amended from time to time.

(b)                Whether or not subject to Section 13 or 15(d) of the Exchange Act and for so long as any Notes are outstanding, Holdings shall file with the Trustee within 15 calendar days after the same are, or would be, required to be filed with the Commission (giving effect to any grace period provided by Rule 12b-25 under the Exchange Act or any successor rule under the Exchange Act), copies of all the quarterly and annual reports and the information, documents and other reports, if any, that Holdings is required, or would be required if Holdings were required to file such reports, information or documents, to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act (excluding, for the avoidance of doubt, any documents or reports (or portions thereof) that are subject to confidential treatment and any correspondence with the Commission). Any such report, information or document that Holdings files with the Commission via the Commission’s EDGAR system (or any successor thereto) shall be deemed to be delivered and filed with the Trustee for purposes of this ‎ Section 4.06(b) at the time such documents are filed via the EDGAR system (or any successor thereto); provided , however , that the Trustee shall have no obligation whatsoever to determine whether or not such information, documents or reports have been filed pursuant to EDGAR (or its successor).

(c)               Delivery of reports, information and documents to the Trustee under this Indenture is for informational purposes only and the information and the Trustee’s receipt of the foregoing shall not constitute constructive notice of any information contained therein, or determinable from information contained therein including the Issuer’s compliance with any of its covenants thereunder (as to which the Trustee is entitled to rely exclusively on an Officers’ Certificate).

(d)                If, at any time during the six-month period beginning on, and including, the date that is six months after the last date of original issuance of the Notes (such date, the “ Original Issuance Date ”), the Issuer 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 reports on Form 8-K), or the Notes are not otherwise freely tradable by Holders other than the Issuer’s Affiliates or Holders that were the Issuer’s Affiliates at any time during the three months preceding (as a result of restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes), the Issuer shall pay Additional Interest on the Notes. In such circumstances, for the first 90 days, Additional Interest shall accrue on the Notes at the rate of 0.25% per annum of the principal amount and for the remaining period at a rate of 0.50% per annum of the principal amount of the Notes outstanding for each day during such period for which the Issuer’s failure to file has occurred and is continuing, or the Notes are not otherwise freely tradable by Holders other than the Issuer’s Affiliates or Holders that have been the Issuer’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); provided, that such Additional Interest shall cease to accrue on the one year anniversary of the Original Issuance Date. As used in this Section 4.06(d), documents or reports that the Issuer is required to “file” with the Commission pursuant to Section 13 or 15(d) of the Exchange Act do not include documents or reports that the Issuer furnishes to the Commission pursuant to Section 13 or 15(d) of the Exchange Act.

(e)               With respect to Notes other than Affiliate Notes, if, and for so long as, the restrictive legend on the Notes specified in Section 2.05(c) has not been removed, the Notes are assigned a restricted CUSIP number or the Notes are not otherwise freely tradable by Holders other than the Issuer’s Affiliates and Holders that were the Issuer’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 of the 365th calendar day after the Original Issuance Date (in each case other than with respect to Affiliate Notes), the Issuer shall pay Additional Interest on the Notes (other than Affiliate Notes) at a rate equal to 0.50% per annum of the principal amount of Notes (other than Affiliate Notes) outstanding until the restrictive legend on the Notes (other than Affiliate Notes) has been removed in accordance with Section 2.05(c), the Notes (other than Affiliate Notes) are assigned an unrestricted CUSIP number and the Notes are freely tradable by Holders other than the Issuer’s Affiliates and Holders that were the Issuer’s Affiliates at any time during the three months preceding. Notwithstanding the foregoing, if the Issuer has complied with all applicable requirements of the Depositary (including all applicable notice requirements) to effect the removal of the restrictive legend on the Notes (other than Affiliate Notes) on or prior to the 365th day after the Original Issuance Date, any Additional Interest that the Issuer would otherwise be required to pay pursuant to this clause (e) for failure to remove the restrictive legend on the Notes will not accrue until the 375th day after the Original Issuance Date.

Section 4.07.      Stay, Extension and Usury Laws. The Issuer and each of the Guarantors covenants (to the extent that they may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law that would prohibit or forgive the Issuer from paying all or any portion of the principal (including the Fundamental Change Repurchase Price and Redemption Price, if applicable) of or interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or that may affect the covenants or the performance of this Indenture; and the Issuer and each of the Guarantors (to the extent they may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

Section 4.08.      Compliance Certificate; Statements as to Defaults. (a) The Issuer shall deliver to the Trustee within 120 calendar days after the end of each fiscal year of the Issuer (beginning with the fiscal year ending on December 31, 2017) an Officers’ Certificate stating whether the signer thereof knows of any failure by the Issuer or any

Guarantor to comply with all conditions and covenants then required to be performed under this Indenture and, if so, specifying each such failure and the nature thereof, its status and what actions the Issuer is taking or proposing to take with respect thereto.

(b)                In addition, the Issuer shall deliver to the Trustee, as soon as possible, and in any event within 10 calendar days after the occurrence of any Default or Event of Default, an Officers’ Certificate describing, in reasonable detail, such Default or Event of Default, its status and the action that the Issuer is taking or proposing to take in respect thereof. The Issuer shall also deliver to the Trustee and the Holders, promptly, such additional information regarding the business or financial affairs of the Issuer or any of its Subsidiaries, or compliance with the terms of this Indenture, as the Trustee or any Holder may from time to time reasonably request during the existence of any Default or Event of Default subject to any such requesting Holder entering into a confidentiality agreement reasonably requested by the Issuer or Holdings.

Section 4.09.      Further Instruments and Acts. Upon request of the Trustee, each Credit Party will, and will cause each of their respective Subsidiaries to, execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to fully consummate all of the transactions contemplated hereby and carry out more effectively the purposes of this Indenture.

Section 4.10.      Additional Amounts . (a) All payments and deliveries made by, or on behalf of, the Issuer under or with respect to the Notes, including, but not limited to, payments of principal (including the Fundamental Change Repurchase Price and Redemption Price, if applicable), payments of interest and deliveries of Common Stock or other Reference Property and/or payments of cash, in each case, upon exchange, shall be made without withholding or deduction for, or on account of, any present or future taxes, duties, assessments or governmental charges of whatever nature (“ Taxes ”) imposed or levied by a taxing authority within any jurisdiction in which Holdings or Issuer is, for tax purposes, organized or resident or doing business or through which payment is made or deemed made (or any political subdivision or taxing authority thereof or therein) (each, as applicable, a “ Relevant Taxing Jurisdiction ”), unless such withholding or deduction is required by law or by the official interpretation or administration thereof. In the event that any such withholding or deduction is so required, Issuer shall pay such additional amounts (the “ Additional Amounts ”) as may be necessary to ensure that the net amount received by the beneficial owner after such withholding or deduction (and after deducting or withholding any Taxes on the Additional Amounts) shall equal the amounts that would have been received by such beneficial owner had no such withholding or deduction been required; provided, that no Additional Amounts shall be payable:

(i)                 for or on account of:

(A)             any Tax that would not have been imposed but for:

otherwise than by acceleration (with interest on such principal and, to the extent that such payment is enforceable under applicable law, on overdue installments of accrued interest not paid or capitalized, at the rate borne by the Notes at such time to the date of such payment or deposit) and amounts due to the Trustee pursuant to ‎Section 7.06, (2) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (3) any and all existing Events of Default under this Indenture, other than the nonpayment of the principal of, and premium, if any, and any interest that has not been paid or capitalized, on Notes that shall not have become due by their terms, shall have been remedied or waived pursuant to ‎Section 6.09, then and in every such case (except as provided in the immediately succeeding sentence) the Holders of a majority in aggregate Initial Principal Amount of the Notes then outstanding, by written notice to the Issuer 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 and Redemption Price, if applicable) of, or any interest that has not been paid or capitalized, on, any Notes, (ii) a failure to repurchase any Notes when required under this Indenture, or (iii) a failure to pay or deliver, as the case may be, the consideration due upon exchange of the Notes.

Without limiting the generality of the foregoing, it is understood and agreed that if the Notes are accelerated in respect of any Event of Default (including, but not limited to, upon the occurrence of a bankruptcy or insolvency event (including the acceleration of claims by operation of law)), the Make-Whole Premium will be due and payable and shall constitute part of the obligations, in view of the impracticability and extreme difficulty of ascertaining actual damages and by mutual agreement of the parties as to a reasonable calculation of each Holder’s lost profits as a result thereof. Any premium payable above shall be presumed to be the liquidated damages sustained by each Holder as the result of the acceleration of the maturity of the Notes and the Issuer agrees that it is reasonable under the circumstances currently existing. The premium shall also be payable in cash in the event the Notes (and/or this Indenture) are satisfied or released by foreclosure (whether by power of judicial proceeding), deed in lieu of foreclosure or by any other means. THE COMPANY EXPRESSLY WAIVES (TO THE FULLEST EXTENT IT MAY LAWFULLY DO SO) THE PROVISIONS OF ANY PRESENT OR FUTURE STATUTE OR LAW THAT PROHIBITS OR MAY PROHIBIT THE COLLECTION OF THE FOREGOING PREMIUM IN CONNECTION WITH ANY SUCH ACCELERATION. The Issuer expressly agrees (to the fullest extent it may lawfully do so) that: (A) the premium is reasonable and is the product of an arm’s length transaction between sophisticated business people, ably represented by counsel; (B) the premium shall be payable notwithstanding the then prevailing market rates at the time payment is made; (C) there has been a course of conduct between holders and the Issuer giving specific consideration in this transaction for such agreement to pay the premium; and (D) the Issuer shall be estopped hereafter from claiming differently than as agreed to

in this paragraph. The Issuer expressly acknowledges that its agreement to pay the premium to Holders as herein described is a material inducement to holders to purchase the Notes.

Section 6.03.      Additional Interest . Notwithstanding anything in this Indenture or in the Notes to the contrary, to the extent that the Issuer elects, the sole remedy for an Event of Default relating to the Issuer’s failure to comply with its obligations as set forth in ‎ Section 4.06(b) shall (i) for the first 180 calendar 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 Capitalized Principal Amount of the Notes outstanding for each day during such 180-calendar day period on which such an Event of Default is continuing and (ii) for the period from, and including, the 181st calendar day after the occurrence of such an Event of Default to, and including, the 270th calendar day after the occurrence of such an Event of Default, consist exclusively of the right to receive Additional Interest on the Notes at a rate equal to 0.50% per annum of the Capitalized Principal Amount of Notes outstanding for each day during such additional 90-calendar day period on which such an Event of Default is continuing (in each case, together with any RRA Additional Interest, the “ Additional Interest ”). Such Additional Interest shall be payable in the same manner and on the same dates as the stated interest payable on the Notes. On the 271st calendar day after such Event of Default (if the Event of Default relating to the Issuer’s failure to comply with its obligations as set forth in ‎ Section 4.06(b) is not cured or waived prior to such 271st calendar day), the Notes shall be immediately subject to acceleration as provided in ‎ Section 6.02. The provisions of this ‎ Section 6.03 will not affect the rights of Holders of Notes in the event of the occurrence of any other Event of Default. In the event the Issuer does not elect to pay Additional Interest following an Event of Default in accordance with this ‎ Section 6.03 or the Issuer elected to make such payment but does not pay or capitalize the Additional Interest when due, the Notes shall be immediately subject to acceleration as provided in ‎ Section 6.02.

In order to elect to pay Additional Interest as the sole remedy during the first 270 calendar days after the occurrence of any Event of Default relating to the Issuer’s failure to comply with its obligations as set forth in ‎Section 4.06(b) described in the immediately preceding paragraph, the Issuer must notify all Holders of the Notes, the Trustee and the Paying Agent (if other than the Trustee) in writing of such election prior to the beginning of such 270-calendar day period. Upon the failure to timely give such notice, the Notes shall be immediately subject to acceleration as provided in ‎Section 6.02. Neither the Trustee nor the Paying Agent shall at any time be under any duty or responsibility to any Holder to determine the Additional Interest, or with respect to the nature, extent, or calculation of the amount of Additional Interest owed, or with respect to the method employed in such calculation of the Additional Interest.

In no event shall Additional Interest payable in the event the Issuer elects to pay Additional Interest in respect of an Event of Default relating to Holdings’ failure to comply with its obligations under ‎Section 4.06(b) as set forth in this ‎Section 6.03, accrue at a rate in excess of 0.50% per annum, regardless of the number of events or circumstances giving rise to the requirement to pay such Additional Interest.

Section 6.04.      Payments of Notes on Default; Suit Therefor. If an Event of Default described in clause ‎ (a) or ‎ (b) of ‎ Section 6.01 shall have occurred, the Issuer 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, if any, at the rate borne by the Notes at such time, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee hereunder. If the Issuer 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 Issuer 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 Issuer 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 Issuer 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, examiner, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the Issuer or such other obligor, the property of the Issuer or such other obligor, or in the event of any other judicial proceedings relative to the Issuer or such other obligor upon the Notes, or to the creditors or property of the Issuer or such other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this ‎Section 6.04, 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 any interest that has not been paid or capitalized, in respect of the Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents and to take such other actions as it may deem necessary or advisable in order to have the claims of the Trustee (including any claim for the compensation, reasonable expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceedings relative to the Issuer or any other obligor on the Notes, its or their creditors, or its or their property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due to the Trustee hereunder; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, examiner, custodian or similar official is hereby authorized by each of the Holders to make such payments to the Trustee, as administrative expenses, and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for compensation, reasonable expenses, advances and disbursements, including agents and counsel fees, and including any other amounts due to the Trustee hereunder, incurred by it up to the date of such distribution. To the extent that such payment of compensation, reasonable 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, its agents and counsel, be for the ratable benefit of the Holders of the Notes.

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

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 to ‎Section 6.09 or any rescission and annulment pursuant to ‎Section 6.02 or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Issuer, 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 Issuer, 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 collected by the Trustee pursuant to this ‎ Article 6 with respect to the Notes shall be applied in the following order, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the several Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid:

First , to the payment of all amounts due the Trustee (in any capacity) and its agents hereunder;

Second , in case the principal of the outstanding Notes shall not have become due and be unpaid, to the payment of interest on, and any cash due upon exchange of, the Notes in default in the order of the date due of the payments of such interest and cash due upon exchange, as the case may be, with interest (to the extent that such interest has been collected by the Trustee) upon such overdue payments at the rate borne by the Notes at such time, such payments to be made ratably to the Persons entitled thereto;

Third , in case the principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment of the whole amount (including, if applicable, the payment of the Fundamental Change Repurchase Price, the Redemption Price and any cash due upon exchange) then owing and unpaid upon the Notes for principal and interest, if any, with interest on the overdue principal and, to the extent that such interest has been collected by the Trustee, upon overdue installments of interest at the rate borne by the Notes at such time, and in case such monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Notes, then to the payment of such principal (including, if applicable, the Fundamental Change Repurchase Price, the Redemption Price and the cash due upon exchange) and interest without preference or priority of principal over interest, or of interest over principal or of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate of such principal (including, if applicable, the Fundamental Change Repurchase Price, the Redemption Price and any cash due upon exchange) and accrued interest not paid or capitalized; and

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

Section 6.06.      Proceedings by Holders. Except to enforce the right to receive payment of principal (including, if applicable, the Fundamental Change Repurchase Price and Redemption Price) or interest when due, or the right to receive payment or delivery of the consideration due upon exchange, no Holder 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 Initial Principal Amount of the Notes then outstanding shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder;

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

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

(e)                no direction that is inconsistent with such written request shall have been given to the Trustee by the Holders of a majority of the aggregate Initial Principal Amount of the Notes then outstanding within such 60-calendar day period pursuant to ‎ Section 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, 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); 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. For the protection and enforcement of this ‎Section 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, the right of any Holder to receive payment or delivery, as the case may be, of (x) the principal (including the Fundamental Change Repurchase Price and Redemption Price, if applicable) of, (y) any interest that has not been paid or capitalized, on, and (z) the consideration due upon exchange of, such Note, on or after the respective due dates expressed or provided for in such Note or in this Indenture, or to bring suit for the enforcement of any such payment or delivery, as the case may be, on or after such respective dates against the Issuer 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 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 of ‎ Section 2.06, all powers and remedies given by this ‎ Article 6 to the Trustee or to the Holders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the Holders of the Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in 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 of ‎ Section 6.06, every power and remedy given by this ‎ Article 6 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Holders.

Section 6.09.      Direction of Proceedings and Waiver of Defaults by Majority of Holders. Subject to the Trustee’s right to request indemnity or security satisfactory to it

from the relevant Holders as described herein, the Holders of a majority of the aggregate Initial Principal Amount of the Notes at the time outstanding determined in accordance with ‎ Section 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 or that would involve the Trustee in personal liability.

Whenever any Default or Event of Default hereunder shall have been waived as permitted by this ‎ Section 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 10 calendar days after it receives notice of the occurrence and continuance of a Default of which a Responsible Officer has actual knowledge, 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 and Redemption Price, if applicable), or accrued interest that has not been paid or capitalized on, any of the Notes or a Default in the payment or delivery of the consideration due upon exchange, the Trustee shall be protected in withholding such notice if and so long as the Trustee in good faith determines that the withholding of such notice is in the interests of the Holders.

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 this ‎ Section 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 Initial Principal Amount of the Notes at the time outstanding determined in accordance with ‎ Section 8.04, or to any suit instituted by any Holder for the enforcement of the payment of the principal of or any interest that has not been paid or capitalized, on any Note (including, but not limited to, the Fundamental Change Repurchase Price and Redemption 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 exchange any Note, or receive the consideration due upon exchange, in accordance with the provisions of ‎ Article 14.

Section 6.12.      Cause Irrelevant. Each of the events enumerated in Section 6.01 hereof will constitute an Event of Default whatever the cause and regardless of whether voluntary or involuntary or 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.

The Trustee shall be under no liability for interest on any money received by it hereunder except as may be agreed in writing from time to time by the Issuer and the Trustee.

Section 7.06.      Compensation and Expenses of Trustee. The Issuer covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, compensation for all services rendered by it hereunder in any capacity (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) as mutually agreed to in writing between the Trustee and the Issuer, and the Issuer will pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any of the provisions of this Indenture in any capacity thereunder (including the reasonable compensation and the expenses and disbursements of its agents and counsel (including fees and expenses of counsel in connection with enforcement of its rights to indemnity hereunder) and of all Persons not regularly in its employ) except any such expense, disbursement or advance as shall have been caused by its gross negligence, willful misconduct or bad faith. The Issuer also covenants to indemnify the Trustee (or any predecessor Trustee) in any capacity under this Indenture and any other document or transaction entered into in connection herewith and its agents and any authenticating agent for, and to hold them harmless against, any loss, claim, damage, liability fee or expense (including attorney’s fees and court costs), including taxes (other than taxes based upon, measured by or determined by the income of the Trustee) incurred without gross negligence, willful misconduct or bad faith on the part of the Trustee, its officers, directors, agents or employees, or such agent or authenticating agent, as the case may be, and arising out of or in connection with the acceptance or administration of this Indenture or in any other capacity hereunder, including the costs and expenses of defending

themselves against any claim or liability (whether asserted by the Issuer, or any Holder or any other Person). The obligations of the Issuer under this ‎ Section 7.06 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall be secured by a senior lien to which the Notes are hereby made subordinate on all money or property held or collected by the Trustee, except, subject to the effect of ‎ Section 6.05, funds held in trust herewith for the benefit of the Holders of particular Notes, and, for the avoidance of doubt, such lien shall not be extended in any manner that would conflict with the Issuer’s obligations to its other creditors. The Trustee’s right to receive payment of any amounts due under this ‎ Section 7.06 shall not be subordinate to any other liability or indebtedness of the Issuer. The obligation of the Issuer under this ‎ Section 7.06 shall survive the satisfaction and discharge of this Indenture and the earlier resignation or removal or the Trustee. The Issuer need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The indemnification provided in this ‎ Section 7.06 shall extend to the officers, directors, agents and employees of the Trustee.

Without prejudice to any other rights available to the Trustee under applicable law, when the Trustee and its agents and any authenticating agent incur expenses or render services after an Event of Default specified in ‎Section 6.01(i) or Section 6.01(j) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any bankruptcy, insolvency or similar laws.

Section 7.07.      Officers’ Certificate as Evidence. Whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or omitting any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of gross negligence, willful misconduct or bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an Officers’ Certificate delivered to the Trustee, and such Officers’ Certificate, in the absence of gross negligence or willful misconduct on the part of the Trustee, shall be full warrant to the Trustee for any action taken or omitted by it under the provisions of this Indenture upon the faith thereof.

Section 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. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.

Section 7.09.      Resignation or Removal of Trustee. (a) The Trustee may at any time resign by giving written notice of such resignation to the Issuer and by delivering notice thereof to the Holders. The Required Holders may remove the Trustee by so

notifying the Trustee and may appoint a successor Trustee. Upon receiving such notice of resignation, the Required Holders shall promptly appoint a successor trustee. If no successor trustee shall have been so appointed and have accepted appointment within 60 calendar days after the delivery of such notice of resignation to the Holders, the resigning Trustee may, at the Issuer’s expense, petition any court of competent jurisdiction for the appointment of a successor trustee Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee.

(b)                In case at any time any of the following shall occur:

(i)                 the Trustee shall fail to be eligible in accordance with the provisions of ‎ Section 7.08 and shall fail to resign after written request therefor by the Issuer or by any such Holder after such failure, or

(ii)               the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation,

such common stock or other equity will be of an entity that is a corporation for United States federal income tax purposes, and (B) expressly assumes by supplemental indenture all of Holdings’ obligations under this Indenture and the Parent Guarantee (including, for the avoidance of doubt, the obligation to pay Additional Amounts) and (y) the board of directors of Holdings and the board of directors of the surviving Person each determine that there is no reasonable concern that, as a result of such consolidation, merger, combination, sale, lease or other transfer or disposition, the surviving Person will not be able to satisfy its obligations to its creditors; and

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

(iii)              For purposes of this Section 11.01, any sale, lease or other transfer or disposition of the assets of one or more Subsidiaries of Holdings (other than the Issuer) to another Person that would, if such assets were held directly by Holdings instead of such Subsidiaries, have constituted the sale, lease or other transfer or disposition of all or substantially all of the consolidated assets of Holdings and its Subsidiaries, taken as a whole, shall be deemed to be the sale, lease or other transfer or disposition of the assets of all or substantially all of the consolidated assets of Holdings and its Subsidiaries, taken as a whole, to another Person.

(b)                Upon any such consolidation, merger, combination, sale, lease or other transfer or disposition and upon the assumption by the Successor Company, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal of and accrued interest that has not been paid or capitalized on, all of the Notes (including, for the avoidance of doubt, any Additional Amounts), the due and punctual delivery and/or payment, as the case may be, of any consideration due upon exchange of the Notes (including, for the avoidance of doubt, any Additional Amounts) and the due and punctual performance of all of the covenants and conditions of this Indenture and the Parent Guarantee to be performed by Holdings, such Successor Company (if not Holdings) shall succeed to, and may exercise every right and power of and be substituted for Holdings with the same effect as if it had been named herein as the party of the first part, and Holdings shall be discharged from its obligations under the this Indenture and the Parent Guarantee, as applicable, except in the case of a lease. In the event of any such consolidation, merger, sale, transfer or disposition (but not in the case of a lease), upon compliance with this Article 11, the Person named as the “Parent Guarantor” in the first paragraph of this Indenture shall be released from its respective liabilities as guarantor and from its obligations under this Indenture and the Parent Guarantee.

Article 12

upon any obligation, covenant or agreement of the Issuer in this Indenture or in any supplemental indenture or in any Note or any Guarantee, 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 Issuer or of any successor corporation, either directly or through the Issuer 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 and the Guarantees.

Article 13
The Guarantees

Section 13.01.   The Guarantees. Subject to the provisions of this ‎ Article 13, each Guarantor hereby irrevocably and unconditionally guarantees, jointly and severally, on an unsecured basis, the full and punctual payment (whether at the Maturity Date, upon redemption, purchase pursuant to an Provisional Redemption or acceleration, or otherwise) of the principal of, premium, if any, and interest on, and all other amounts payable under, each Note, and the full and punctual payment of all other amounts payable by the Issuer under this Indenture. Upon failure by the Issuer to pay punctually any such amount, each Guarantor shall forthwith on demand pay the amount not so paid at the place and in the manner specified in this Indenture. Each guarantee shall be a guarantee of payment and not of collection.

Section 13.02.   Guarantee Unconditional. The obligations of each Guarantor hereunder are unconditional and absolute and, without limiting the generality of the foregoing, will not be released, discharged or otherwise affected by

(1)        any extension, renewal, settlement, compromise, waiver or release in respect of any obligation of the Issuer under this Indenture or any Note, by operation of law or otherwise;

(2)        any modification or amendment of or supplement to this Indenture or any Note;

(3)        any change in the corporate existence, structure or ownership of the Issuer, or any insolvency, bankruptcy, examinership, reorganization or other similar proceeding affecting the Issuer or its assets or any resulting release or discharge of any obligation of the Issuer contained in this Indenture or any Note;

(4)        the existence of any claim, set-off or other rights which the Guarantor may have at any time against the Issuer, the Trustee or any other Person, whether in connection with this Indenture or any unrelated transactions, provided, that nothing herein prevents the assertion of any such claim by separate suit or compulsory counterclaim;

(5)        any invalidity or unenforceability relating to or against the Issuer for any reason of this Indenture or any Note, or any provision of applicable law or regulation purporting to prohibit the payment by the Issuer of the principal of or interest on any Note or any other amount payable by the Issuer under this Indenture; or

(6)        any other act or omission to act or delay of any kind by the Issuer, the Trustee or any other Person or any other circumstance whatsoever which might, but for the provisions of this paragraph, constitute a legal or equitable discharge of or defense to such Guarantor’s obligations hereunder.

Section 13.03.   Discharge; Reinstatement. Each Guarantor’s obligations hereunder will remain in full force and effect until the principal of, premium, if any, and interest on the Notes and all other amounts payable by the Issuer under this Indenture have been paid in full. If at any time any payment of the principal of, premium, if any, or interest on any Note or any other amount payable by the Issuer under this Indenture is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy or reorganization of the Issuer or otherwise, each Guarantor’s obligations hereunder with respect to such payment will be reinstated as though such payment had been due but not made at such time.

Section 13.04.   Waiver by the Guarantors. Each Guarantor irrevocably waives acceptance hereof, presentment, demand, protest and any notice not provided for herein, as well as any requirement that at any time any action be taken by any Person against the Issuer or any other Person.

Section 13.05.   Subrogation and Contribution. Upon making any payment with respect to any obligation of the Issuer under this Article, the Guarantor (other than Holdings or Pernix Therapeutics, LLC) making such payment will be subrogated to the rights of the payee against the Issuer with respect to such obligation, provided, that the Guarantor (other than Holdings or Pernix Therapeutics, LLC) may not enforce either any right of subrogation, or any right to receive payment in the nature of contribution, or otherwise, from any other Guarantor (other than Holdings or Pernix Therapeutics, LLC), with respect to such payment so long as any amount payable by the Issuer hereunder or under the Notes remains unpaid.

Section 13.06.   Stay of Acceleration. If acceleration of the time for payment of any amount payable by the Issuer under this Indenture or the Notes is stayed upon the insolvency, bankruptcy, examinership or reorganization of the Issuer, all such amounts otherwise subject to acceleration under the terms of this Indenture are nonetheless payable by the Guarantors hereunder forthwith on demand by the Trustee or the Holders.

Section 13.07.   Limitation on Amount of Guarantee. (a) Notwithstanding anything to the contrary in this Article, each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Note Guarantee of such Guarantor not constitute a fraudulent conveyance under applicable fraudulent conveyance provisions of the Bankruptcy Code or any comparable provision of state law.

To effectuate that intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of each Guarantor under its Note Guarantee are limited to the maximum amount that would not render the Guarantor’s obligations subject to avoidance under applicable fraudulent conveyance provisions of the Bankruptcy Code or any comparable provision of state law.

(b)                In respect of a Guarantor which is a company incorporated under the laws of the Republic of Ireland, the obligations of any such Guarantor under the Note Guarantee are limited to the maximum amount which would not render such Guarantor’s obligations the provision of unlawful financial assistance within the meaning of section 82 of the Companies Act 2014 of Ireland.

Section 13.08.   Execution and Delivery of Guarantee. The execution by each Guarantor of this Indenture (or a supplemental indenture in the form of Exhibit B) evidences the Note Guarantee of such Guarantor, whether or not the person signing as an officer of the Guarantor still holds that office at the time of authentication of any Note. The delivery of any Note by the Trustee after authentication constitutes due delivery of the Note Guarantee set forth in this Indenture on behalf of each Guarantor.

Section 13.09.   Release of Guarantees. So long as no Default or Event of Default has occurred and is continuing or would result therefrom, the Note Guarantee of a Subsidiary Guarantor will be released (upon the execution by the Trustee of the documents described in the succeeding paragraph) upon:

(1)        a sale or other disposition of the Subsidiary Guarantor or the sale or disposition of all or substantially all the assets of the Subsidiary Guarantor (in each case other than to Holdings, any Subsidiary of Holdings or any of their respective Affiliates) that complies with Sections 4.05 and 4.16 and is otherwise permitted by this Indenture; and

(2)        defeasance or discharge of the Notes, as provided in “Satisfaction and Discharge.”

The Issuer shall deliver to the Trustee of an Officers’ Certificate and an Opinion of Counsel that all conditions precedent to the release of the Note Guarantee have been complied with and that the release of the Note Guarantee is permitted by this Indenture, whereupon the Trustee will execute any documents reasonably required (and prepared by and at the expense of the Issuer) in order to evidence the release of the Subsidiary Guarantor from its obligations under its Note Guarantee.

Article 14
Exchange of Notes

Section 14.01.   Exchange Privilege. (a) Subject to and upon compliance with the provisions of this ‎ Article 14, each Holder of a Note shall have the right, at such Holder’s option, to exchange all or any portion of such Note at any time prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date,

in each case, at an initial exchange price of $5.50 per share of Common Stock (subject to adjustment as provided in this ‎ Article 14, the “ Exchange Price ”) (subject to, and in accordance with, the settlement provisions of ‎ Section 14.02, the “ Exchange Obligation ”). The Exchange Price on any Exchange Date will not be increased in connection with any increase in the Capitalized Principal Amount.

(b)                If the Issuer provides a Redemption Notice pursuant to Section 16.02 in respect of a Provisional Redemption, Holders may exchange all or any portion of their Notes at any time prior to the close of business on the second Scheduled Trading Day preceding the Redemption Date (a “ Redemption Exchange Period ”). After that time, a Holder’s right to exchange its Notes called for redemption will expire unless the Issuer defaults in the payment of the Redemption Price, in which case a Holder may exchange its Notes called for redemption until the Redemption Price is paid or duly provided for.

(c)                 If a Holder exchanges all or any portion of its Notes in connection with a Provisional Redemption, the Exchange Price shall be decreased pursuant to Section 14.03.

Section 14.02.   Exchange Procedure; Settlement Upon Exchange . (a) Subject to this ‎ Section 14.02, ‎ Section 14.03(b) and ‎ Section 14.07(a), upon exchange of any Note, the Issuer shall pay to the exchanging Holder, in respect of each $1,000 Initial Principal Amount of Notes being exchanged, cash (“ Cash Settlement ”), shares of Common Stock, together with cash, if applicable, in lieu of delivering any fractional share of Common Stock in accordance with subsection ‎ (j) of this ‎ Section 14.02 shall be delivered to the exchanging Holder (“ Physical Settlement ”) or a combination of cash and shares of Common Stock shall be delivered to the exchanging Holder, together with cash to be paid by the Issuer, if applicable, in lieu of delivering any fractional share of Common Stock in accordance with subsection ‎ (j) of this ‎ Section 14.02 (“ Combination Settlement ”), at the Issuer’s election, as set forth in this ‎ Section 14.02. Any Settlement Notice containing the Issuer's election shall include an acknowledgment by Holdings that Holdings has directed the Issuer to make such election .

(i)                  All exchanges for which the relevant Exchange Date occurs during the period from, and including, the 25th Scheduled Trading Day immediately preceding the Maturity Date to, and including, the second Scheduled Trading Day immediately preceding the Maturity Date shall be settled using the same Settlement Method and all exchanges for which the relevant Exchange Date occurs during a Redemption Exchange Period shall be settled using (A) Combination Settlement (if there is an effective registration statement under the Securities Act relating to the offer and sale of the shares of Common Stock to be delivered upon such exchange and Holdings reasonably expects such registration statement to remain effective for the next 30 Scheduled Trading Days following the date such shares of Common Stock would be delivered to the Holder) or (B) Cash Settlement (if there is no effective registration statement under the Securities Act relating to the offer and sale of the shares of Common Stock to be delivered upon an exchange or Holdings does not reasonably expect to maintain the effectiveness of a registration statement under the Securities Act for the next 30

Scheduled Trading Days following the date such shares of Common Stock would be delivered by Holdings to the Holders).

(ii)                Except for any exchanges described in ‎ Section 14.02(a)(i), the same Settlement Method shall apply for all exchanges with the same Exchange Date, but there is no obligation to use the same Settlement Method with respect to exchanges with different Exchange Dates.

(iii)              If, in respect of any Exchange Date (or the period from, and including, the 25th Scheduled Trading Day immediately preceding the Maturity Date to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date), the Issuer (acting on the direction of Holdings) elects to deliver a notice (the “ Settlement Notice ”) of the relevant Settlement Method in respect of such Exchange Date (or such period, as the case may be), the Issuer shall notify the Trustee and the Exchange Agent (if other than the Trustee) in writing and shall cause such Settlement Notice to be delivered to exchanging Holders no later than the close of business on the second Trading Day immediately following the relevant Exchange Date (or, in the case of any exchanges occurring during the period from, and including, the 25th Scheduled Trading Day immediately preceding the Maturity Date to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date), no later than the close of business on the 25th Scheduled Trading Day immediately preceding the Maturity Date, in the related Redemption Notice. If the Issuer (acting on the direction of Holdings) does not elect a Settlement Method prior to the deadline set forth in the immediately preceding sentence, the Issuer shall no longer have the right to elect Cash Settlement or Physical Settlement and the Issuer shall be deemed to have elected Combination Settlement in respect of its Exchange Obligation, and the Specified Dollar Amount per $1,000 Initial Principal Amount of Notes shall be equal to $1,000. 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 Initial Principal Amount of Notes. If the Issuer delivers a Settlement Notice electing (or is deemed to have elected) Combination Settlement in respect of its Exchange Obligation but does not indicate a Specified Dollar Amount per $1,000 Initial Principal Amount of Notes in such Settlement Notice, the Specified Dollar Amount per $1,000 Initial Principal Amount of Notes shall be deemed to be $1,000. The Issuer (acting on the direction of Holdings) may at any time prior to the 25th Scheduled Trading Day immediately preceding the Maturity Date irrevocably elect to settle all exchanges through Combination Settlement with a Specified Dollar Amount that Holdings elects.

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

(A)              if the Issuer (acting on the direction of Holdings) elects to satisfy its Exchange Obligation in respect of such exchange by Physical Settlement, Holdings shall deliver to the exchanging Holder in respect of each $1,000 Initial Principal Amount of Notes being exchanged a number of shares of Common Stock equal to the applicable Exchange Amount in effect on the Exchange Date plus cash in lieu of delivering any fractional share;

(B)               if the Issuer (acting on the direction of Holdings) elects to satisfy the Exchange Obligation in respect of such exchange by Cash Settlement, the Issuer shall pay to the exchanging Holder in respect of each $1,000 Initial Principal Amount of Notes being exchanged cash in an amount equal to the sum of the applicable Daily Exchange Values for each of the 20 consecutive Trading Days during the related Observation Period; and

(C)               if the Issuer elects (acting on the direction of Holdings, or is deemed to have elected) to satisfy its Exchange Obligation in respect of such exchange by Combination Settlement, the Issuer shall pay or Holdings shall deliver, as the case may be, in respect of each $1,000 Initial Principal Amount of Notes being exchanged, a Settlement Amount equal to the sum of the applicable Daily Settlement Amounts for each of the 20 consecutive Trading Days during the relevant Observation Period.

(v)                The Daily Settlement Amounts (if applicable) and the Daily Exchange Values (if applicable) shall be determined by the Issuer promptly following the last day of the Observation Period. Promptly after such determination of the Daily Settlement Amounts or the Daily Exchange Values, as the case may be, and the amount of cash payable in lieu of delivering any fractional share of Common Stock, the Issuer shall notify the Trustee and the Exchange Agent (if other than the Trustee) in writing of the Daily Settlement Amounts or the Daily Exchange 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 Exchange Agent (if other than the Trustee) shall have no responsibility for any such determination.

(vi)              For the avoidance of doubt, in connection with any Physical Settlement or Combination Settlement, the obligations of Holdings under this Indenture is, inter alia, to issue such shares of Common Stock as required hereunder and nothing in this Indenture shall require the Issuer to acquire, hold or subscribe for Common Stock in Holdings and the Issuer shall have no obligation to deliver Common Stock.

(b)                Subject to ‎ Section 14.02(e), before any Holder of a Note shall be entitled to exchange a Note as set forth above, such Holder shall (i) in the case of a Global Note, comply with the procedures of the Depositary in effect at that time (allowing for sufficient time to comply) and, if required, (1) pay funds to the Exchange Agent equal to

interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in ‎ Section 14.02(h) and (2) pay all transfer and similar taxes as set forth in ‎ Section 14.02(d) and ‎ Section 14.02(e); and (ii) in the case of a Physical Note (1) complete, manually sign and deliver an irrevocable notice to the Exchange Agent as set forth in the Form of Notice of Exchange (or a facsimile thereof) (a “ Notice of Exchange ”) at the office of the Exchange Agent and state in writing therein the principal amount of Notes to be exchanged 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 Exchange Obligation to be registered, (2) surrender such Notes, duly endorsed to the Issuer or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the Exchange Agent, (3) if required, furnish appropriate endorsements and transfer documents, (4) if required, pay all transfer and similar taxes as set forth in ‎ Section 14.02(d) and ‎ Section 14.02(e) and (5) if required, pay funds to the Exchange Agent equal to the interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in ‎ Section 14.02(h). The Exchange Agent shall notify the Issuer of any exchange pursuant to this ‎ Article 14 on the Exchange Date for such exchange. No Notice of Exchange with respect to any Notes may be surrendered by a Holder thereof if such Holder has also delivered a Fundamental Change Repurchase Notice to the Issuer in respect of such Notes and has not validly withdrawn such Fundamental Change Repurchase Notice in accordance with ‎ Section 15.03.

If more than one Note shall be surrendered for exchange at one time by the same Holder, the Exchange Obligation with respect to such Notes shall be computed on the basis of the aggregate Initial 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 exchanged immediately prior to the close of business on the date (the “ Exchange Date ”) that the Holder has complied with the requirements set forth in subsection (b) above. Except as set forth in ‎ Section 14.03(b) and ‎ Section 14.07(a), the Issuer shall pay or Holdings shall deliver, as the case may be, the consideration due in respect of the Exchange Obligation on the third Business Day immediately following the relevant Exchange Date, if the Issuer (acting on the direction of Holdings) elects to satisfy the Exchange Obligation by Physical Settlement, or on the third 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 exchanging Holders, Holdings shall issue or cause to be issued, and deliver to such Holder, or such Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the full number of shares of Common Stock to which such Holder shall be entitled in satisfaction of the Exchange Obligation.

(d)                In case any Physical Note shall be surrendered for partial exchange, the Issuer shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Physical Note so surrendered a new Physical Note or Physical Notes in authorized denominations in an aggregate Initial Principal Amount equal to the unexchanged portion of the surrendered Physical Note, without payment of any service charge by the exchanging Holder but, if required by the Issuer 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 Physical Notes issued upon such exchange being different from the name of the Holder of the old Physical Notes surrendered for such exchange.

(e)                 If a Holder submits a Note for exchange, Holdings shall pay any documentary, stamp or similar issue or transfer tax due on the issue of any shares of Common Stock upon exchange, unless the tax is due because the Holder requests any such shares to be issued in a name other than the Holder’s name, in which case the Holder must pay that tax. The Issuer 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 Issuer receives a sum sufficient to pay any tax that is due by such Holder in accordance with the immediately preceding sentence.

(f)                 Except as provided in ‎ Section 14.04, no adjustment shall be made for dividends on any shares of Common Stock issued upon the exchange of any Note as provided in this ‎ Article 14.

(g)                Upon the exchange 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 Initial Principal Amount represented thereby. The Issuer shall notify the Trustee in writing of any exchange of Notes effected through any Exchange Agent other than the Trustee.

(h)                Upon exchange, a Holder shall not receive any separate cash payment for any interest that has not been paid or capitalized, except as set forth below. The settlement of the full Exchange Obligation shall be deemed to satisfy in full its obligation to pay the Capitalized Principal Amount of the Note and any accrued interest that has not been paid or capitalized to, but excluding, the relevant Exchange Date. As a result, any accrued interest that has not been paid or capitalized to, but excluding, the relevant Exchange Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon an exchange of Notes into a combination of cash and shares of Common Stock, any accrued interest that has not been paid or capitalized will be deemed to be paid first out of the cash paid upon such exchange. Notwithstanding the foregoing, if Notes are exchanged after the close of business on a Regular Record Date, Holders of such Notes as of the close of business on such Regular Record Date will receive the full amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the exchange. Notes surrendered for exchange during the period beginning after the close of business on any Regular Record Date and ending at the open of business on the immediately following Interest Payment Date must be accompanied by funds equal to the amount of interest payable on the Notes so exchanged assuming such interest will be paid by the All Cash Method (and the Issuer shall be deemed to have elected the All Cash Method with respect to the payment of such interest); provided that no such payment shall be required (1) for Notes surrendered for exchange after the close of business on the Regular Record Date immediately preceding the Maturity Date; (2) if the Issuer has specified a Redemption Date that is after a Regular Record Date and on or

prior to the second Scheduled Trading Day immediately following the date on which the corresponding interest payment is made; (3) if the Issuer has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the second Scheduled Trading Day immediately following the corresponding Interest Payment Date; or (4) to the extent of any Defaulted Amounts, if any Defaulted Amounts exists at the time of exchange with respect to such Note. Therefore, for the avoidance of doubt, all Holders of record on the Regular Record Date immediately preceding the Maturity Date, any Redemption Date described in clause (2) and any Fundamental Change Repurchase Date described in clause (3) of the immediately preceding sentence shall receive the full interest payment due on the Maturity Date or other applicable Interest Payment Date regardless of whether their Notes have been exchanged or repurchased, as applicable, following such Regular Record Date.

(i)                  The Person in whose name the shares of Common Stock shall be issuable upon exchange shall be treated as a stockholder of record as of the close of business on the relevant Exchange Date (if the Issuer elects (acting on the direction of Holdings), or Holdings is required, to satisfy the related Exchange Obligation by Physical Settlement) or the last Trading Day of the relevant Observation Period (if the Issuer and Holdings satisfy the related Exchange Obligation by Combination Settlement), as the case may be. Upon an exchange of Notes, such Person shall no longer be a Holder of such Notes surrendered for exchange.

(j)                  Holdings shall not issue any fractional share of Common Stock upon exchange of the Notes and the Issuer shall instead pay cash in lieu of delivering any fractional share of Common Stock issuable upon exchange based on the Daily VWAP on the relevant Exchange Date (in the case of Physical Settlement) or based on the Daily VWAP on the last Trading Day of the relevant Observation Period (in the case of Combination Settlement). For each Note surrendered for exchange, if the Issuer has elected Combination Settlement (acting on the direction of Holdings), the full number of shares that shall be issued upon exchange 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.   Adjustment to Exchange Price upon Exchange upon a Make-Whole Fundamental Change or a Provisional Redemption. (a) If, (i) prior to the Maturity Date, a Make-Whole Fundamental Change occurs or (ii) the Issuer calls the Notes for Provisional Redemption pursuant to ‎ Section 16.01, and a Holder elects to exchange its Notes in connection with such Make-Whole Fundamental Change or Provisional Redemption, the Issuer shall, under the circumstances described below, decrease the Exchange Price for the Notes so surrendered for exchange, as described below. An exchange of Notes shall be deemed for these purposes to be “in connection with” (x) such Make-Whole Fundamental Change if the relevant Notice of Exchange for such Notes is received by the Exchange Agent from, and including, the Effective Date up to, and including, the second Business Day immediately prior to the related Fundamental Change Repurchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for the proviso in clause (b) of the definition thereof, the 35th Trading Day immediately following the Effective Date) or (y) such Provisional

Redemption if the relevant Notice of Exchange for such Notes is received by the Exchange Agent during the relevant Redemption Exchange Period.

(b)                Upon surrender of Notes for exchange in connection with a Make-Whole Fundamental Change or a Provisional Redemption, the Issuer (together with Holdings in respect of a Physical Settlement or Combination Settlement) at its option shall satisfy the related Exchange Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with ‎ Section 14.02; provided , however , that if, at the effective time of a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Reference Property following such Make-Whole Fundamental Change is composed entirely of cash, for any exchange of Notes following the Effective Date, the Exchange 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 Initial Principal Amount of exchanged Notes equal to the product of the Stock Price times the quotient of the Capitalized Principal Amount in respect of such $1,000 Initial Principal Amount divided by the Exchange Price (including any adjustment as described in this ‎ Section 14.03). In such event, the Exchange Obligation shall be determined and paid to Holders in cash on the third Business Day following the Exchange Date. The Issuer shall notify the Holders and the Trustee in writing of any Effective Date no later than five Business Days after such Effective Date.

(c)                 The amount, if any, by which the Exchange Price shall be decreased 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 ”) or the Redemption Notice Date, as applicable, and the price paid (or deemed to be paid) per share of the Common Stock in the Make-Whole Fundamental Change or the stock price with respect to the Redemption Date (as determined below), as applicable (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. In the case of any other Make-Whole Fundamental Change, the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock over the five Trading Day period ending on, and including, the Trading Day immediately preceding the Effective Date. The Stock Price in connection with a Provisional Redemption shall be the average of the Last Reported Sale Prices of the Common Stock over the five Trading Day period ending on, and including, the Trading Day immediately preceding the Redemption Notice Date. In the event that an exchange in connection with a Provisional Redemption would also be deemed to be in connection with a Make-Whole Fundamental Change, a Holder of the Notes to be exchanged shall be entitled to a single decrease to the Exchange Price with respect to the first to occur of the applicable Redemption Notice Date or the Effective Date of the applicable Make-Whole Fundamental Change, and the later event will be deemed not to have occurred for purposes of this ‎ Section 14.03. The Board of Directors and board of directors of Holdings shall make appropriate adjustments to the Stock Price, in their good faith determination, to account for any adjustment to the Exchange Price that becomes effective, or any event requiring an adjustment to the Exchange Price where the Ex-Dividend Date, Effective Date or expiration date of the event occurs during such five 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 Exchange Price 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 denominator of which is the Exchange Price immediately prior to such adjustment giving rise to the Stock Price adjustment and the numerator is the Exchange Price as so adjusted. The amount by which the Exchange Price will be decreased as set forth in the table below shall be adjusted in the same manner and at the same time as the Exchange Price as set forth in ‎ Section 14.04.

(e)                 The following table sets forth the amount, if any, by which the Exchange Price will be decreased pursuant to this ‎ Section 14.03 for each Stock Price and Effective Date or Redemption Notice Date, as applicable, set forth below:

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

(i)                  if the Stock Price is between two Stock Prices in the table above or the Effective Date or Redemption Notice Date is between two dates in the table, the amount by which the Exchange Price shall be decreased shall be determined by a straight-line interpolation between the amount of the Exchange Price decrease set forth for the higher and lower Stock Prices and the earlier and later dates based on a 365-calendar day year;

(ii)                if the Stock Price is greater than $20.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant to subsection ‎ (d) above), the Exchange Price shall not be decreased; and

(iii)              if the Stock Price is less than $4.49 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant to subsection ‎ (d) above), the Exchange Price shall not be decreased.

Notwithstanding the foregoing, in no event shall the Exchange Price be decreased below $4.49, subject to adjustment in the same manner as the Exchange Price pursuant to ‎ Section 14.04.

(f)                 Nothing in this ‎ Section 14.03 shall prevent an adjustment to the Exchange Price pursuant to ‎ Section 14.04 in respect of a Make-Whole Fundamental Change or during a Redemption Exchange Period.

Section 14.04.   Adjustment of Exchange Price. The Exchange Price shall be adjusted from time to time by the Issuer if any of the following events occurs, except that the Issuer shall not make any adjustments to the Exchange Price if Holders of the Notes participate (other than in the case of (x) a share split or share combination or (y) a tender or exchange offer, in each case, that would result in an adjustment to the Exchange Price pursuant to ‎ Section 14.04(a) or ‎ Section 14.04(e) below), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Notes, in any of the transactions described in this ‎ Section 14.04, without having to exchange their Notes, as if they held a number of shares of Common Stock in respect of each $1,000 Initial Principal Amount of Notes held by such Holder equal to the Exchange Amount.

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

where,

EP ₀ =      the Exchange Price in effect immediately prior to the open of business on the Ex-Dividend Date of such dividend or distribution, or immediately prior to the open of business on the Effective Date of such share split or share combination, as applicable;

EP ₁ =      the Exchange Price in effect immediately after the open of business on such Ex-Dividend Date or Effective Date;

OS ₀ =     the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date or Effective Date; and

OS ₁ =     the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination.

Any adjustment made under this ‎ Section 14.04(a) shall become effective immediately after the open of business on the Ex-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 this ‎ Section 14.04(a) is declared but not so paid or made, the Exchange Price shall be immediately readjusted, effective as of the date the board of directors of Holdings determines not to pay such dividend or distribution, to the Exchange Price that would then be in effect if such dividend or distribution had not been declared.

(b)                If Holdings issues to all or substantially all holders of Common Stock any rights, options or warrants entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of Common Stock at a price per share that is less than the average of the Last Reported Sale

Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, the Exchange Price shall be decreased based on the following formula:

where,

EP ₀ =      the Exchange Price in effect immediately prior to the open of business on the Ex-Dividend Date for such issuance;

EP ₁ =      the Exchange Price in effect immediately after the open of business on such Ex-Dividend Date;

OS ₀ =     the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-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 decrease made under this ‎ Section 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 the Ex-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 Exchange Price shall be increased to the Exchange Price that would then be in effect had the decrease 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 Exchange Price shall be increased to the Exchange Price that would then be in effect if such Ex-Dividend Date for such issuance had not occurred.

For purposes of this ‎ Section 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 a price per share that is less than such average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by Holdings 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 of Holdings.

(c)                 If Holdings distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of Holdings or rights, options or warrants to acquire shares of its Capital Stock or other securities, to all or substantially all holders of the Common Stock, excluding (i) dividends, distributions or issuances as to which an adjustment was effected pursuant to ‎ Section 14.04(a) or ‎ Section 14.04(b), (ii) dividends or distributions paid exclusively in cash as to which an adjustment was effected pursuant to ‎ Section 14.04(d), (iii) any dividends or distributions of Reference Property in exchange for Common Stock in connection with any transaction described in ‎ Section 14.07, (iv) except as otherwise provided in ‎ Section 14.11, rights issued pursuant to a shareholder rights plan adopted by Holdings and (v) Spin-Offs as to which the provisions set forth below in this ‎ Section 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 shares of Capital Stock or other securities, the “ Distributed Property ”), then the Exchange Price shall be decreased based on the following formula:

where,

EP ₀ =    the Exchange Price in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;

EP ₁ =    the Exchange Price in effect immediately after the open of business on such Ex-Dividend Date;

SP ₀ =    the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and

FMV =   the fair market value (as determined by the board of directors of Holdings) of the Distributed Property with respect to each outstanding share of Common Stock on the Ex-Dividend Date for such distribution.

Any decrease made under the portion of this ‎ Section 14.04(c) above shall become effective immediately after the open of business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Exchange Price shall be increased to be the Exchange Price 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 “SP ₀ ” (as defined above), in lieu of the foregoing decrease, each Holder of a Note shall receive, in respect of each $1,000 Initial 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 Exchange Amount in effect on the Record Date for the distribution. If the board of directors of Holdings determines the “FMV” (as defined above) of any distribution for purposes of

this ‎ Section 14.04(c) by reference to the actual or when-issued trading market for any securities, it shall in doing so consider the prices in such market over the same period used in computing the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution.

With respect to an adjustment pursuant to this ‎ Section 14.04(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 Holdings, that are, or, when issued, will be, listed or admitted for trading on a U.S. national securities exchange (a “ Spin-Off ”), the Exchange Price shall be decreased based on the following formula:

where,

EP ₀ =     the Exchange Price in effect immediately prior to the open of business on the Ex-Dividend Date for such Spin-Off;

EP ₁ =     the Exchange Price in effect immediately after the open of business on the Ex-Dividend Date for such Spin-Off;

FMV ₀ = the average of the Last Reported Sale Prices of the shares of Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of Common Stock (determined by reference to the definition of Last Reported Sale Price as set forth in ‎ Section 1.01 as if references therein to Common Stock were to such Capital Stock or similar equity interest) over the first 10 consecutive Trading Day period after, and including, the Ex-Dividend Date of the Spin-Off (the “ Valuation Period ”); and

MP ₀ =    the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period.

The decrease to the Exchange Price under the preceding paragraph shall be determined on the last Trading Day of the Valuation Period, but shall be given effect at the open of business on the Ex-Dividend Date for such Spin-Off. Notwithstanding the foregoing, in respect of any exchange of Notes during the Valuation Period, references in the portion of this ‎ Section 14.04(c) related to Spin-Offs with respect to 10 consecutive Trading Days shall be deemed to be replaced with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date of such Spin-Off to, but excluding, the Exchange Date in determining the Exchange Price. If the Ex-Dividend Date for the Spin-Off is less than 10 Trading Days prior to, and including, the end of the Observation Period in respect of any exchange of Notes, references in the preceding paragraph to 10 consecutive Trading Days will be deemed to be replaced, solely in respect of that exchange of Notes, with such lesser number of Trading Days as have

elapsed from, and including, the Ex-Dividend Date for the Spin-Off to, and including, the last Trading Day of such Observation Period. If such Spin-Off does not occur, the Exchange Price shall be increased to be the Exchange Price that would then be in effect if such distribution had not been declared, effective as of the date on which the board of directors of Holdings determines not to consummate such Spin-Off.

For purposes of this ‎ Section 14.04(c) (and subject in all respect to ‎ Section 14.11), rights, options or warrants distributed by Holdings to all holders of the Common Stock entitling them to subscribe for or purchase shares of Holdings’ 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 (“ Triggering Event ”): (i) are deemed to be transferred with such shares of the Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of the Common Stock, shall be deemed not to have been distributed for purposes of this ‎ Section 14.04(c) (and no adjustment to the Exchange Price under this ‎ Section 14.04(c) will be required) until the occurrence of the earliest Triggering Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Exchange Price shall be made under this ‎ Section 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 and Ex-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 Triggering 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 Exchange Price under this ‎ Section 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 redemption or purchase (x) the Exchange Price shall be readjusted as if such rights, options or warrants had not been issued and (y) the Exchange Price shall then again be readjusted to give effect to such distribution, deemed distribution or Triggering Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by a holder or holders of Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights, options or warrants that shall have expired or been terminated (or deemed to have expired or been terminated pursuant to the immediately preceding sentence) without exercise by any holders thereof, the Exchange Price shall be readjusted as if such rights, options and warrants had not been issued (to the extent any adjustment to the Exchange Price was made in connection with such issuance).

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

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

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

then, in either case, (1) such dividend or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this ‎ Section 14.04(c) is applicable (the “ Clause C Distribution ”) and any Exchange Price adjustment required by this ‎ Section 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 Exchange Price adjustment required by ‎ Section 14.04(a) and ‎ Section 14.04(b) with respect thereto shall then be made, except that, if determined by the Issuer (I) the “Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution shall be deemed to be the Ex-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 such Ex-Dividend Date or Effective Date” within the meaning of ‎ Section 14.04(a) or “outstanding immediately prior to the open of business on such Ex-Dividend Date” within the meaning of ‎ Section 14.04(b).

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

where,

EP ₀ =   the Exchange Price in effect immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution;

EP ₁ =   the Exchange Price in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution;

SP ₀ =  the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and

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

Any decrease made under this ‎ Section 14.04(d) shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution. If such dividend or distribution is not so paid, the Exchange Price shall be increased, effective as of the date the board of directors of Holdings determines not to make or pay such dividend or distribution, to be the Exchange Price 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 “SP ₀ ” (as defined above), in lieu of the foregoing decrease, each Holder of a Note shall receive, for each $1,000 Initial 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 Exchange Amount on the Ex-Dividend Date for such cash dividend or distribution.

(e)                 If Holdings or any of its Subsidiaries makes 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 Common Stock exceeds the Last Reported Sale Price of the Common Stock on the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer, the Exchange Price shall be decreased based on the following formula:

where,

EP ₀ =     the Exchange Price in effect immediately prior to the open of business on the Trading Day next succeeding the date such tender or exchange offer expires;

EP ₁ =     the Exchange Price in effect immediately after the open of business on the Trading Day next succeeding the date such tender or exchange offer expires;

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

OS ₀ =   the number of shares of Common Stock outstanding immediately prior to the open of business on the date such tender or exchange offer expires (prior to giving effect to the purchase or exchange of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer);

OS ₁ =    the number of shares of Common Stock outstanding immediately after the open of business on the date such tender or exchange offer expires (after giving effect to the purchase or exchange of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer); and

SP ₁ =     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 decrease to the Exchange Price under this ‎ Section 14.04(e) shall be determined at the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires, but shall be given effect at the open of business on the Trading Day next succeeding the date such tender or exchange offer expires. Notwithstanding the foregoing, in respect of any exchange of Notes within the 10 Trading Days immediately following, and including, the Trading Day next succeeding the expiration date of any tender or exchange offer, references in this ‎ Section 14.04(e) with respect to 10 consecutive Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the expiration date of such tender or exchange offer and the Exchange Date in determining the Exchange Price. In addition, if the Trading Day next succeeding the expiration date for such tender or exchange offer is less than 10 Trading Days prior to, and including, the end of the Observation Period (if applicable) in respect of any exchange of Notes, references in the preceding paragraph to 10 consecutive Trading Days shall be deemed to be replaced, solely in respect of that exchange of Notes, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the expiration date for such tender or exchange offer to, and including, the last Trading Day of such Observation Period. For the avoidance of doubt, no adjustment pursuant to this ‎ Section 14.04(e) shall be made if such adjustment would result in an increase in the Exchange Price.

If Holdings is obligated to purchase shares of the Common Stock pursuant to any such tender or exchange offer described in this ‎ Section 14.04(e) but is permanently prevented by applicable law from effecting any such purchase or all such purchases are rescinded, the applicable Exchange Price shall be readjusted to be the Exchange Price that would then be in effect if such tender or exchange offer had not been made or had been made only in respect of the purchases that have been effected.

(f)                 Notwithstanding this ‎ Section 14.04 or any other provision of this Indenture or the Notes, if an Exchange Price adjustment becomes effective on any Ex-Dividend Date, and a Holder that has exchanged its Notes on or after such Ex-Dividend Date and on or prior to the related Record Date would be treated as the record holder of the shares of Common Stock as of the related Exchange Date as described under ‎ Section 14.02(i) based on an adjusted Exchange Price for such Ex-Dividend Date, then, notwithstanding the Exchange Price adjustment provisions in this ‎ Section 14.04, the Exchange Price adjustment relating to such Ex-Dividend Date shall not be made for such exchanging 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 Issuer shall not adjust the Exchange Price for the issuance of shares of the Common Stock or any securities convertible into or

exchangeable for shares of the Common Stock or the right to purchase shares of the Common Stock or such convertible or exchangeable securities.

(h)                In addition to those adjustments required by clauses ‎ (a), ‎ (b), ‎ (c), ‎ (d) and ‎ (e) of this ‎ Section 14.04, and to the extent permitted by applicable law and subject to the applicable listing standards of The NASDAQ Global Market (or of any other exchange on which any of Holdings’ securities are then listed), the Issuer from time to time may decrease the Exchange Price by any amount for a period of at least 20 Business Days if the Board of Directors and the board of directors of Holdings determines that such decrease would be in Holdings’ and the Issuer’s best interest. In addition, to the extent permitted by applicable law and subject to the applicable listing standards of The NASDAQ Global Market (or of any other exchange on which any of Holdings’ securities are then listed), the Issuer may (but is not required to) decrease the Exchange Price to avoid or diminish any income tax to holders of Common Stock or rights to purchase shares of 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 Exchange Price is decreased pursuant to either of the preceding two sentences, the Issuer shall deliver to the Holder of each Note a notice of the decrease at least 15 calendar days prior to the date the decreased Exchange Price takes effect, and such notice shall state the decreased Exchange Price and the period during which it will be in effect.

(i)                  Notwithstanding anything to the contrary in this ‎ Article 14, the Exchange Price 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 Holdings’ 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 Holdings or any of Holdings’ Subsidiaries;

(iii)              except as set forth in ‎ Section 14.04(b) or ‎ Section 14.04(c), upon the issuance of any shares of the Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in clause ‎ (ii) of this subsection;

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

(v)                upon the repurchase of any shares of the Common Stock pursuant to an open-market share repurchase program or other buy-back transaction that is not a tender offer or exchange offer of the kind described in ‎ Section 14.04(e); or

(vi)              for any interest that has not been paid or capitalized.

(j)                  All calculations and other determinations under this ‎ Article 14 shall be made by the Issuer and shall be made to the nearest cent.

(k)                Whenever the Exchange Price is adjusted as herein provided, the Issuer shall promptly file with the Trustee (and the Exchange Agent if not the Trustee) an Officers’ Certificate setting forth the Exchange Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee (and the Exchange Agent if not the Trustee) shall have received such Officers’ Certificate, the Trustee (and the Exchange Agent if not the Trustee) shall not be deemed to have knowledge of any adjustment of the Exchange Price and may assume without inquiry that the last Exchange Price of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Issuer shall prepare a notice of such adjustment of the Exchange Price setting forth the adjusted Exchange Price and the date on which each adjustment becomes effective and shall deliver such notice of such adjustment of the Exchange Price to each Holder. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

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

(m)              If, in the case of any exchange of a Note to which Combination Settlement applies, on any Trading Day during the Observation Period for such Note, shares of Common Stock are deliverable as part of the Daily Settlement Amount for such Trading Day, and

(i)                  the Ex-Dividend Date for any issuance, dividend or distribution, the Effective Date for any share split or combination or the expiration date for any tender offer or exchange offer by Holdings (or, in the case of a tender offer or exchange offer, by one of Holdings’ Subsidiaries) that, in each case, would require an adjustment to the Exchange Price under clauses (a) through (e) of this Section 14.04 occurs prior to the Issuer’s delivery of such shares of Common Stock to the exchanging Holder;

(ii)                the applicable Exchange Price for such Trading Day will not reflect such adjustment; and

(iii)              the shares of Common Stock that Holdings will deliver to the exchanging Holder with respect to such Trading Day are not entitled to participate in the relevant event (because the exchanging Holder is not treated as the holder of such shares of Common Stock on the related Ex-Dividend Date, Effective Date, expiration date or otherwise),

then the Issuer shall adjust the number of shares that Holdings delivers to such Holder as part of the Daily Settlement Amount for such Trading Day in a manner that the Board of Directors and the board of directors of Holdings determine appropriately reflects the relevant issuance, dividend, distribution, transaction or event.

Section 14.05.   Adjustments of Prices. Whenever any provision of this Indenture requires the Issuer to calculate the Last Reported Sale Prices, the Daily VWAPs, the Daily Exchange Values or the Daily Settlement Amounts over a span of multiple days (including an Observation Period and, if applicable, the period for determining the Stock Price for purposes of a Make-Whole Fundamental Change), the Board of Directors shall make appropriate adjustments (to the extent no corresponding adjustment is otherwise made pursuant to ‎ Section 14.04) to each to account for any adjustment to the Exchange Price that becomes effective, or any event requiring an adjustment to the Exchange Price where the Ex-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 Exchange Values or the Daily Settlement Amounts are to be calculated.

Section 14.06.   Shares to Be Reserved. Holdings 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 exchange of the Notes from time to time as such Notes are presented for exchange (assuming that at the time of computation of such number of shares, all such Notes would be exchanged by a single Holder and that Physical Settlement were applicable). Neither Holdings nor the Issuer shall take any action that would require an adjustment to the Exchange Price pursuant to Section 14.04 such that the maximum number of shares of Common Stock issuable upon the exchange of all of the Outstanding Notes (taking into account Section 14.03) would exceed the number of then-authorized but unissued shares of Common Stock (or shares of Common Stock held in treasury) not reserved for other purposes.

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 Holdings;

(iii)              any sale, lease or other transfer to a third party of the consolidated assets of Holdings and its 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) (each, a “ Specified Corporate Event ”), then the Issuer and Holdings or the Issuer and the Successor Company, as the case may be, shall execute with the Trustee a supplemental indenture permitted under Section 10.01 (l) providing

that, at and after the effective time of such Specified Corporate Event, the right to exchange each $1,000 Initial Principal Amount of Notes shall be changed into a right to exchange 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 Exchange Amount immediately prior to such Specified Corporate Event would have owned or been entitled to receive (the “ Reference Property ,” with each “ unit of Reference Property ” meaning the kind and amount of Reference Property that a holder of one share of Common Stock is entitled to receive) upon the occurrence of such Specified Corporate Event; provided , however , that at and after the effective time of the Specified Corporate Event, (A) then the Issuer (acting on the direction of Holdings) or the Successor Company, as the case may be, shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon exchange of Notes in accordance with ‎ Section 14.02 and (B) (x) any amount payable in cash upon exchange of the Notes in accordance with ‎ Section 14.02 shall continue to be payable in cash, (y) any shares of Common Stock that Holdings would have been required to deliver upon exchange of the Notes in accordance with ‎ Section 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 Specified Corporate Event and (z) the Daily VWAP shall be calculated based on the value of a unit of Reference Property.

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

Such supplemental indenture described in the second immediately preceding paragraph shall provide for (x) anti-dilution adjustments that shall be as nearly equivalent as practicable to the adjustments provided for in this ‎ Article 14, with respect to any

Reference Property consisting of shares of Common Equity, and (y) with respect to any other Reference Property, such adjustments (if any) that the Board of Directors and the board of directors of Holdings determine in good faith are appropriate. If, in the case of any Specified Corporate Event, the Reference Property includes shares of stock, securities or other property or assets (other than cash and/or cash equivalents) of a Person other than the Issuer or the Successor Company, as the case may be, in such Specified Corporate 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 and the board of directors of Holdings shall reasonably consider necessary by reason of the foregoing, including the provisions providing for the repurchase rights set forth in ‎ Article 15.

(b)                When the Issuer executes a supplemental indenture pursuant to subsection ‎ (a) of this ‎ Section 14.07, the Issuer 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 Specified Corporate 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 Issuer shall cause notice of the execution of such supplemental indenture to be delivered to each Holder within 20 calendar days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

(c)                 Neither the Issuer nor Holdings shall become a party to any Specified Corporate Event unless its terms are consistent with this ‎ Section 14.07. None of the foregoing provisions shall affect the right of a Holder to exchange its Notes into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, all as set forth in ‎ Section 14.01 and ‎ Section 14.02, prior to the effective date of such Specified Corporate Event.

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

Section 14.08.   Certain Covenants. (a) Each of the Issuer and Holdings covenants that all shares of Common Stock issued upon exchange of Notes will be fully paid and non-assessable by Holdings and free from all taxes, liens and charges with respect to the issue thereof.

(b)                Each of the Issuer and Holdings covenants that, if any shares of Common Stock to be provided for the purpose of exchange 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 exchange, Holdings 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)                 Each of the Issuer and Holdings further covenant that if at any time the Common Stock shall be listed on any national securities exchange or automated quotation

system Holdings will list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated quotation system, any Common Stock issuable upon exchange of the Notes.

Section 14.09.   Responsibility of Trustee. The Trustee and any other Exchange Agent shall not at any time be under any duty or responsibility to any Holder to determine the Exchange Price (or any adjustment thereto) or whether any facts exist that may require any adjustment of the Exchange Price, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Exchange 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 exchange of any Note; and the Trustee and any other Exchange Agent make no representations with respect thereto. Neither the Trustee nor any Exchange Agent shall be responsible for any failure of the Issuer and Holdings to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Note for the purpose of exchange or to comply with any of the duties, responsibilities or covenants of the Issuer and Holdings contained herein. Without limiting the generality of the foregoing, neither the Trustee nor any Exchange Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to ‎ Section 14.07 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Holders upon the exchange of their Notes after any event referred to in such ‎ Section 14.07 or to any adjustment to be made with respect thereto, but, subject to the provisions of ‎ Section 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 Issuer shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. Neither the Trustee nor the Exchange Agent shall be responsible for determining whether any event contemplated by Section 14.01(b) has occurred that makes the Notes eligible for exchange or no longer eligible therefor until the Issuer has delivered to the Trustee and the Exchange Agent the notices referred to in Section 14.01(b) with respect to the commencement or termination of such exchange rights, on which notices the Trustee and the Exchange Agent may conclusively rely, and the Issuer agrees to deliver such notices to the Trustee and the Exchange Agent immediately after the occurrence of any such event or at such other times as shall be provided for in Section 14.01(b).

Section 14.10.   Notice to Holders Prior to Certain Actions . In case of any:

(a)                 action by Holdings or one of its Subsidiaries that would require an adjustment in the Exchange Price pursuant to ‎ Section 14.04 or ‎ Section 14.11;

(b)                Specified Corporate Event; or

(c)                 voluntary or involuntary dissolution, liquidation or winding-up of Holdings;

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

Section 14.11.   Shareholder Rights Plans. If Holdings has a shareholder rights plan in effect upon exchange of the Notes, each share of Common Stock, if any, issued upon such exchange shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such exchange shall bear such legends, if any, in each case as may be provided by the terms of any such shareholder rights plan, as the same may be amended from time to time. However, if, prior to any exchange of Notes, the rights have separated from the shares of Common Stock in accordance with the provisions of the applicable shareholder rights plan, the Exchange Price shall be adjusted at the time of separation as if Holdings distributed to all or substantially all holders of the Common Stock Distributed Property as provided in ‎ Section 14.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights.

Section 14.12.   Exchange to Financial Institutions Designated by the Issuer . Notwithstanding anything herein to the contrary, when a Holder surrenders Notes for exchange, the Issuer or Holdings (as applicable) may, at its election (an “ Exchange Election ”), direct the Exchange Agent to surrender, on or prior to the second Trading Day following the Exchange Date, such Notes to a financial institution designated by Holdings for exchange by such financial institution in lieu of exchange by the Issuer or Holdings (as applicable). In order to accept any Notes surrendered for exchange, the designated financial institution must agree to timely deliver, in exchange for such Notes, the cash, shares of Common Stock or combination thereof due upon exchange at the time and in the manner provided in this ‎ Article 14. If the Issuer or Holdings (as applicable) makes an Exchange Election, the Issuer shall, by the close of business on the second Trading Day following the relevant Exchange Date, notify the Holder surrendering its Notes for exchange that the Issuer or Holdings (as applicable) has made the Exchange Election and the Issuer or Holdings (as applicable) shall notify the designated financial institution of the Settlement Method the Issuer or Holdings (as applicable) has elected with respect to such exchange and the relevant deadline for payment and/or delivery of the cash, shares of Common Stock, cash or a combination thereof due upon exchange.

Any Notes exchanged by the designated financial institution shall remain Outstanding. If the designated financial institution agrees to accept any Notes for

exchange but does not timely pay and/or deliver the required cash, shares of Common Stock or a combination thereof due upon exchange, or if such designated financial institution does not accept the Notes for exchange, the Issuer or Holdings (as applicable) shall pay and/or deliver the required cash, shares of Common Stock or a combination thereof due upon exchange to the exchanging Holder at the time and in the manner provided in this ‎ Article 14 as if the Issuer or Holdings (as applicable) had not made an Exchange Election.

The designation of a financial institution to which Notes may be submitted for exchange does not require the financial institution to accept any Notes (unless the financial institution has separately made an agreement with the Issuer and/or Holdings (as applicable)). The Issuer and/or Holdings (as applicable) may, but is not obligated to, enter into a separate agreement with any designated financial institution that would compensate it for any such transactions.

Section 14.13.   Certain Limitations on Settlement. For so long as the Common Stock is registered under the Exchange Act, a beneficial owner of the Notes shall not be entitled to receive shares of Common Stock upon exchange of any Notes during any period of time in which the aggregate number of shares of Common Stock that may be acquired by such beneficial owner upon exchange of the Notes shall, when added to the aggregate number of shares of Common Stock deemed beneficially owned, directly or indirectly, by such beneficial owner and each person subject to aggregation of Common Stock ownership with such beneficial owner under Section 13 or Section 16 of the Exchange Act and the rules and regulations promulgated thereunder at such time, including without limitation each “group” of which such beneficial owner is a member (an “ Aggregated Person ”), as determined pursuant to the rules and regulations promulgated under Section 13(d) of the Exchange Act, exceed 9.99% (the “ Restricted Ownership Percentage ”) of the total issued and outstanding shares of Common Stock (the “ Section 16 Exchange Blocker ”).

Notwithstanding the foregoing, Holdings shall issue shares of Common Stock upon exchange of such beneficial owner’s Notes up to (but not exceeding) the number of shares of Common Stock that would cause such beneficial owner’s beneficial ownership of Common Stock (together with that of any Aggregated Person) to equal the Restricted Ownership Percentage; provided, that each beneficial owner shall have the right at any time and from time to time to reduce the Restricted Ownership Percentage applicable to such beneficial owner immediately upon prior written notice to Holdings ( provided, that, for the avoidance of doubt, in such event, such beneficial owner may sell shares of Common Stock or Notes to reduce the aggregate number of shares of Common Stock deemed beneficially owned by such beneficial owner (together with any Aggregated Person) to a level below the reduced Restricted Ownership Percentage, in which case the Notes will be exchangeable by such beneficial owner up to (but will not exceed) the reduced Restricted Ownership Percentage) or increase the Restricted Ownership Percentage applicable to such beneficial owner (together with any Aggregated Person) upon 65 days’ prior written notice to Holdings (but in no case can the Restricted Ownership Percentage be increased above 9.99%).

Under no circumstances shall the Trustee or the Exchange Agent have any obligation to identify any beneficial owner of the Notes, or otherwise make any determination, monitor or otherwise take any action with respect to the restrictions set forth in this Section 14.13.

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 Notice shall specify:

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 Issuer to repurchase their Notes.

No failure of the Issuer to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Notes pursuant to this ‎ Section 15.02.

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

(d)                Notwithstanding the foregoing, no Notes may be repurchased by the Issuer 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 Issuer 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 Issuer in the payment of the Fundamental Change Repurchase Price with respect to such Notes), or any instructions for book-entry transfer of the Notes in compliance with the procedures of the Depositary shall be deemed to have been cancelled, and, upon such return or cancellation, as the case may be, the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn.

If the Trustee selects a portion of a Holder’s Notes for partial redemption and such Holder exchanges a portion of such Notes, the exchanged portion will be deemed to be from the portion selected for redemption. In the event of any redemption in part, the Issuer shall not be required to register the transfer of or exchange any Note so selected for redemption, in whole or in part, except the unredeemed portion of any such Note being redeemed in part.

No Notes may be redeemed if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to the redemption date (except in the case of an acceleration resulting from a default by the Issuer in the payment of the Redemption Price with respect to such Notes).

If the Trustee selects a portion of a Holder’s Notes for partial redemption and such Holder exchanges a portion of such Notes, the exchanged portion will be deemed to be from the portion selected for redemption. In the event of any redemption in part, the Issuer shall not be required to register the transfer of or exchange any Note so selected for redemption, in whole or in part, except the unredeemed portion of any such Note being redeemed in part.

(d) If the Issuer provides a Redemption Repayment Notice pursuant to this Section 16.03, Holders may exchange all or any portion of their Notes at any time prior to the close of business on the second Scheduled Trading Day preceding the Repayment Triggering Event Redemption Date. After that time, a Holder’s right to exchange its Notes called for redemption pursuant to this Section 16.03 will expire unless the Issuer defaults in the payment of the consideration due under this Section 16.03, in which case a Holder may exchange its Notes called for redemption pursuant to this Section 16.03 until such consideration is paid or duly provided for.
