WHEREAS, all acts and things necessary to make the Notes, when executed by the Company and authenticated and delivered by the Trustee or a duly authorized authenticating agent, as in this Indenture provided, the valid, binding and legal obligations of the Company, and this Indenture a valid agreement according to its terms, have been done and performed, and the execution of this Indenture and the issuance hereunder of the Notes have in all respects been duly authorized.

The parties hereto agree that in no event shall this Agreement or any other Note Document, or any provision thereof, be deemed to prohibit any issuance of Qualified Stock by the Company in exchange for outstanding Indebtedness (including Indebtedness under this Indenture and the Notes) or in a capital raising or other transaction, except to the extent such issuance, exchange or capital raising or other transaction would otherwise be expressly prohibited by this Agreement or any other Notes Document.

Notwithstanding anything to the contrary set forth in this Agreement or any other Note Document (excluding, in the case of the Braidwell Holders and the Deerfield Holders, the Exchange Agreement between the Company, Initial Braidwell Investor, and the Initial Deerfield Investor), the Company, the Trustee and the Holders hereby acknowledge and agree that, as of the Closing Date, the

20

Trustee and the Holders desire not to receive reports, notices, documentation and other information (collectively, “Information”) which the Company reasonably believes may contain material non-public information with respect to the Company or any of its Subsidiaries, and the Company shall not provide such Information to the Trustee and the Holders, in each case, for so long as the Company is subject to the reporting requirements of Section 13 or Section 15 of the Exchange Act. Notwithstanding the foregoing, any Holder may, upon written notice to the Company, change its election as to receiving material non-public information (generally or in respect of particular Information or categories thereof).

Notwithstanding the foregoing, only the provisions of Section 8(f) of the Exchange Agreement between the Company, Initial Braidwell Investor, and the Initial Deerfield Investor, rather than this Section 1.05, shall be applicable with respect to each of the Braidwell Holders and the Deerfield Holders.

Article 2

The aggregate principal amount of Notes that may be authenticated and delivered under this Indenture is limited to $232,852,195.80, 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.

(a)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. Any PIK Notes that are Physical Notes will be issued with the designation “PIK Note” on the face of such PIK Note. To the extent applicable, the Company, the Trustee and the Collateral Agent, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling.

(b)All of the Notes shall be issued initially in the form of, at the option of each Investor, (i) one or more Physical Notes, registered in such names and authorized in such denominations as an Investor shall request, duly executed by the Company and authenticated by the Trustee as hereinafter provided or (ii) subject to the Notes meeting the eligibility requirements of the Depositary one or more Notes in global form (each, a “Global Note”), which shall be assigned one or more CUSIP numbers and be deposited on behalf of such Holder with the Trustee, at its Corporate Trust Office, as custodian for the Depositary, duly executed by the Company and authenticated by the Trustee as hereinafter provided. Upon request of any Holder, subject to the Notes meeting the eligibility requirements of the Depositary, any of such Holder’s Physical Notes shall be exchanged for one or more Global Notes no later than two (2) Trading Days (or, if less, the number of days comprising the Standard Settlement Period) following the delivery by a Holder to the Company of a written request for such exchange. Upon request of any Holder, any of such Holder’s beneficial interests in the Notes represented by a Global Note shall be exchanged for one or more Physical Notes no later than two (2) Trading Days (or, if less, the number of days comprising the Standard Settlement Period) following the delivery by a Holder to the Company of a written request for such exchange. The transfer and exchange of beneficial interests in a Global Note that do not involve the issuance of a Physical Note shall be effected through the Depositary (but not the Trustee or the Custodian) in accordance with the Indenture (including the restrictions on transfer set forth herein) and the procedures for the Depositary therefor. Each Physical Note or Global Note, as applicable, shall represent such principal amount of the outstanding Notes as shall be specified therein and each shall provide that it shall represent the aggregate principal amount of the outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of the outstanding Notes represented thereby may from time to time be increased or reduced to reflect repurchases, cancellations, transfers or exchanges permitted thereby. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the amount of outstanding Notes represented thereby shall be made by the Trustee or the Custodian, at the direction of the Trustee, in such manner and upon instructions given by the Holder of such Notes in accordance with this Indenture. Payment of principal (the Optional Redemption Price, and the Make Whole Amount, in each case if applicable) of, and accrued and unpaid interest, if any, on, a Global Note shall be made to the Holder of such Notes on the date of payment, unless a record date or other means of determining Holders eligible to receive payment is provided for herein.

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

21

designated for issuance or to conform with any usage with respect thereto, or to indicate any such 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 the Authorized 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.

(c)If requested by any Investor, the Company shall execute and the Trustee shall, in accordance with this Section 2.02(c) authenticate and deliver initially one or more Physical Notes that (1) shall be registered in such names and authorized in such denominations as each Investor shall request, and (2) shall be delivered by the Trustee to each Investor or pursuant to such Investor’s instructions as specified in the applicable Company Order.

(d)If requested by any Investor, the Company shall execute and the Trustee shall, in accordance with this Section 2.02(d), authenticate and deliver one or more Global Notes that (1) shall be registered in the name of the Depositary, (2) shall be delivered by the Trustee to the Depositary or pursuant to the Depositary’s instructions, (3) shall be assigned a restricted or unrestricted CUSIP number, as applicable, and (4) shall bear a legend substantially to the following effect:

“UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION, TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (AND ANY PAYMENT HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN. THIS SECURITY IS A GLOBAL NOTE WITHIN THE MEANING OF THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITARY OR A NOMINEE THEREOF. THIS SECURITY IS EXCHANGEABLE FOR SECURITIES REGISTERED IN THE NAME OF A PERSON OTHER THAN THE DEPOSITARY OR ITS NOMINEE ONLY AS DESCRIBED IN THE INDENTURE AND UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR SECURITIES IN DEFINITIVE FORM, THIS SECURITY MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE 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 OF ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR DEPOSITARY.”

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

None of the Trustee, the Note Registrar, or the Paying Agent shall have any obligation or duty to monitor, determine or inquire as to compliance with any restrictions on the transfer of any interest in any Notes imposed under this Indenture or under Applicable Laws (including any transfers between or among Depositary participants 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.

Neither the Trustee nor any agent shall have any responsibility or liability for any actions taken or not taken by the Depositary.

(e)If the Company elects to pay PIK Interest in respect of the Notes as set forth in Section 2.03 below, either the outstanding principal amount of the Notes shall be increased to reflect such PIK Interest or additional Notes (the “PIK Notes”) reflecting such PIK Interest shall be issued under this Indenture having the same terms (except that PIK Notes shall be made in a minimum denomination of $1.00 and integral multiples of $1.00) as the Notes (in each case, a “PIK Payment”), as provided in Section 2.03(b). In the event that the Company shall determine to pay PIK Interest for any Interest Period, then the Company shall deliver a PIK Notice (as defined below) to the Trustee as required by the form of Note in Exhibit A. Any PIK Notes will be considered to be part of the same series of, and rank equally and ratably with all other, Notes issued under this Indenture. The aggregate

22

principal amount of outstanding Notes represented by a Global Note shall from time to time be increased, as applicable, to reflect PIK Interest.

(f)    The legend substantially in the following form shall also be included on any Notes issued with OID, as defined below:

THE FOLLOWING INFORMATION IS SUPPLIED SOLELY FOR U.S. FEDERAL INCOME TAX PURPOSES. THIS NOTE WAS ISSUED WITH ORIGINAL ISSUE DISCOUNT (“OID”) WITHIN THE MEANING OF SECTION 1273 OF THE INTERNAL REVENUE CODE OF 1986, AS AMENDED (THE “CODE”), AND THIS LEGEND IS REQUIRED BY SECTION 1275(c) OF THE CODE. UPON REQUEST, THE ISSUER WILL PROMPTLY MAKE AVAILABLE TO A HOLDER OF THIS NOTE INFORMATION REGARDING THE ISSUE PRICE, AMOUNT OF OID, ISSUE DATE AND YIELD TO MATURITY OF THE NOTES BY SUBMITTING A WRITTEN REQUEST FOR SUCH INFORMATION TO THE ISSUER AT NANOSTRING TECHNOLOGIES, INC. 530 FAIRVIEW AVENUE NORTH, SEATTLE, WA 98109, ATTENTION: LEGAL DEPARTMENT, OR VIA FAX AT (206) 378-6288.

Section 2.03    Date and Denomination of Notes; Payments of Interest and Defaulted Amounts.

(a)The Notes shall be issuable only in registered form without coupons and only in denominations of $1,000 principal amount and integral multiples thereof; provided that after the issuance of PIK Notes or an increase in the principal amount of a Global Note in order to evidence PIK Interest, a principal amount of $1.00 and integral multiples of $1.00 in excess thereof. Each Note shall be dated the date of its authentication. The Notes shall bear interest at a rate of 6.95% per year from and including the Closing Date, or from the most recent date to which interest has been paid or provided for to, but excluding the next scheduled Interest Payment Date, if applicable, until the Maturity Date or until the principal thereof and any unpaid and accrued interest thereon are paid or duly provided for. Interest shall be paid in cash; provided that from the Closing Date until December 15, 2024, the Company shall be permitted to elect to pay interest in kind as PIK Interest in accordance with Section 2.03(b). Accrued interest on the Notes shall be computed on the basis of a 360-day year composed of twelve 30-day months and, for partial months, on the basis of the number of days actually elapsed in a 30-day month.

(b)PIK Interest.

(i)In the absence of a Default or Event of Default, the Company may determine to pay any PIK Interest for any Interest Period on or prior to December 15, 2024 (the “PIK Election Period”); provided that the Company shall deliver a notice (a “PIK Notice”) to the Trustee and the Holders not less than five (5) Business Days prior to the Interest Payment Date of the relevant Interest Period, which notice shall state the total amount of interest to be paid on the Interest Payment Date in respect of such Interest Period and the amount of such interest to be paid as PIK Interest and the amount of such interest to be paid in cash; provided that during the PIK Election Period, so long as a Default or Event of Default has not occurred or is continuing, in the event of a PIK Notice is not delivered or not delivered in a timely manner, the Company is deemed to have elected PIK Interest and selected to pay 100% of such interest as PIK Interest. For the avoidance of doubt, all interest due and payable after December 15, 2024 or if a Default or Event of Default has occurred and is continuing shall be paid entirely in cash.

(ii)Any PIK Interest on the Notes will be payable to Holders and (x) with respect to the Notes represented by one or more Global Notes registered in the name of, or held by, the Depositary or its nominee on the relevant Regular Record Date, by increasing the principal amount of the outstanding Global Notes by an amount equal to the amount of PIK Interest for the applicable Interest Period (rounded down to the nearest whole dollar), and the Trustee will, upon receipt of an authentication order from the Company, record such increase in principal amount and (y) with respect to Notes represented by Physical Notes, by issuing PIK Notes in the form of Physical Notes in an aggregate principal amount equal to the amount of PIK Interest for the applicable Interest Period (rounded down to the nearest whole dollar), and the Trustee will, upon receipt of an authentication order and PIK Notes from the Company, authenticate and deliver such PIK Notes in certificated form for original issuance to the Holders on the relevant record date, as shown by the records of the register of Holders. In the event that the Company is entitled to and elects to pay PIK Interest constituting a portion of the interest then due and payable for any Interest Period, each Holder will be entitled to receive cash in respect of the applicable percentage of the principal amount of the Notes held by such Holder on the relevant record date and PIK Interest in respect of the remaining percentage of the principal amount of the Notes held by such Holder on the relevant record date. Following an increase in the principal amount of the outstanding Global Notes as a result of a PIK Payment, the Global Notes will bear interest on such increased principal amount from and after the date of such PIK Payment. Any PIK Notes issued in the form of Physical Notes will be distributed to Holders, will be dated as of the applicable Interest Payment Date and will bear interest from and after such date in accordance with the terms of this Indenture. All Notes issued pursuant to a PIK Payment will mature on the Maturity Date and will be governed by, and subject to the terms, provisions and conditions of, the Indenture and shall have the same rights and benefits as the other

23

Notes. Any PIK Notes issued in the form of Physical Notes will be issued with the description “PIK Note” on the face of such PIK Note.

(iii)If the Company pays a portion of the interest on the Notes in cash and a portion as PIK Interest, such cash and PIK Interest shall be paid to Holders pro rata in accordance with their respective principal amounts of their Notes.

(iv)Notwithstanding anything to the contrary, the payment of accrued interest in connection with any repayment, redemption, repurchase, discharge or defeasance of the Notes as described Articles 15 or Article 16 of this Indenture or otherwise, or during the existence of a Default or Event of Default or an exercise of enforcement rights and remedies, shall be made solely in cash.

(c)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 on such Interest Payment Date. In the case of Physical Notes, payments in respect of principal and interest shall be made in U.S. dollars (i) to any Holder holding such Notes at the office or agency maintained by the Company for such purposes, which shall initially be the Corporate Trust Office or, at the Company’s option, by check mailed to the Holder’s address as it appears in the Note Register or (ii) upon any application to the Paying Agent not later than the relevant Regular Record Date by a Holder of more than $1,000,000 in principal amount of Notes, by wire transfer in immediately available funds to that Holder’s account within the United States, which application shall remain in effect until such Holder notifies, in writing, the Paying Agent to the contrary. Payments in respect of the principal and interest, if any, on any Global Note shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. Notwithstanding anything to the contrary herein, the Company may pay interest at its option to any Holder by wire transfer of immediately available funds to that Holder’s account, as specified by such Holder, within the United States of America.

(d)Any Defaulted Amounts shall accrue interest per annum at the rate borne by the Notes plus four percent (4%), subject to the enforceability thereof under Applicable Law, from, and including, such relevant payment date, and such Defaulted Amounts together with such interest thereon shall be paid by the Company, at its election in each case, as provided in clause (i) or (ii) of Section 2.03(d) below:

(i)The Company may elect to make payment of any Defaulted Amounts to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on a special record date for the payment of such Defaulted Amounts, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of the Defaulted Amounts proposed to be paid on each Note and the date of the proposed payment (which shall be not less than 25 days after the receipt by the Trustee of such notice, unless the Trustee shall consent to an earlier date), and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount to be paid in respect of such Defaulted Amounts or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Amounts as in this clause provided. Thereupon the Company shall fix a special record date for the payment of such Defaulted Amounts which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment, and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Company shall promptly notify the Trustee of such special record date and the Trustee, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Amounts and the special record date therefor to be delivered to each Holder at its address as it appears in the Note Register, or by electronic means to the Depositary in the case of Global Notes, not less than 10 days prior to such special record date. Notice of the proposed payment of such Defaulted Amounts and the special record date therefor having been so delivered, such Defaulted Amounts shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on such special record date and shall no longer be payable pursuant to the following clause (ii) of this Section 2.03(d).

(ii)The Company may make payment of any Defaulted Amounts in any other lawful manner not inconsistent with the requirements of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, and upon such notice as may be required by such exchange or automated quotation system, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee (acting at the direction of the Administrative Determination Holder(s), prior to the Braidwell Disposition Date, the Braidwell Holders, and prior to the Deerfield Disposition Date, the Deerfield Holders).

24

(e)    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 Defaulted Amounts owed, or with respect to the method employed in such calculation of the Defaulted Amounts.

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

Subject to Section 2.01, at any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Notes executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Notes, and the Trustee in accordance with such Company Order shall authenticate and deliver such Notes as provided in this Indenture, without any further action by the Company hereunder; provided that the Trustee shall be entitled to receive an Officer’s Certificate and an Opinion of Counsel with respect to such issuance, authentication and delivery of such Notes.

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 the Trustee (or an authenticating agent appointed by the Trustee as provided by Section 19.09), shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. Such certificate by the Trustee (or such an authenticating agent) upon any Note executed by the Company shall be conclusive evidence that the Note so authenticated has been duly authenticated and delivered hereunder and that the Holder is entitled to the benefits of this Indenture.

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

Section 2.05    Exchange and Registration of Transfer of Notes; Restrictions on Transfer; Depositary.

(a)The Company shall cause to be kept at the Corporate Trust Office a register (the register maintained in such office or in any other office or agency of the Company designated pursuant to Section 4.02, the “Note Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Notes and of transfers of Notes. Such register be in written form or in any form capable of being converted into written form within a reasonable period of time. The Trustee is hereby initially appointed the “Note Registrar” for the purpose of registering Notes and transfers of Notes as herein provided. The Company may appoint one or 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 Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denominations and of a like aggregate principal amount and bearing such restrictive legends as may be required by this Indenture.

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

All Notes presented or surrendered for registration of transfer or for exchange or repurchase shall (if so required by the Company, 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 Company and duly executed, by the Holder thereof or its attorney-in-fact duly authorized in writing.

No service charge shall be imposed by the Company, the Trustee, the Note Registrar, any co-Note Registrar or the Paying Agent for any exchange or registration of transfer of Notes, but the Company, the Trustee, the Note Registrar, any co-Note Registrar or the Paying Agent 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

25

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 Company, the Trustee, the Note Registrar or any co-Note Registrar shall be required to exchange or register a transfer of any Notes, or a portion of any Note, surrendered for Optional Redemption in accordance with Article 16.

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

(b)[Reserved].

Section 2.06    Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become mutilated or be destroyed, lost or stolen, upon request and satisfaction of the conditions of the immediately succeeding sentence, the Company shall execute, and upon its receipt of a Company 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, at the expense of the Holder of such Note. In every case the applicant for a substituted Note shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such indemnity as may be required by them to save each of them harmless from any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof. The Trustee or such authenticating agent may authenticate any such substituted Note and deliver the same upon the receipt of such indemnity as the Trustee, the Company and, if applicable, such authenticating agent may require. No service charge shall be imposed by the Company, the Trustee, the Note Registrar, any co-Note Registrar or the Paying Agent upon the issuance of any substitute Note, but the Company, the Trustee, the Note Registrar, any co-Note Registrar or the Paying Agent 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 shall become mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the payment of the same (without surrender thereof except in the case of a mutilated Note), if the applicant for such payment shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, evidence satisfactory to the Company, the Trustee and, if applicable, or any Paying 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 Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set forth in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement, payment, 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, or repurchase of negotiable instruments or other securities without their surrender.

Section 2.07    Temporary Notes. Pending the preparation of Physical Notes, the Company may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon receipt of a Company 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 Company. Every such temporary Note shall be executed by the Company and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Physical Notes. Without unreasonable delay, the Company shall execute and deliver to the Trustee or such authenticating agent Physical Notes (other than any Global Note) and thereupon any or all temporary Notes (other than any Global Note) may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 4.02 and the Trustee or such authenticating agent shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of Physical Notes. Such exchange shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be

26

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, Etc. The Company, Note Registrar, and Paying Agent shall cause all Notes surrendered to them by Holders for the purpose of payment, Change of Control Repayment, Optional Redemption, registration of transfer or exchange to be surrendered to the Trustee. All Notes so delivered to the Trustee for cancellation shall be canceled promptly by it and such Notes may not be reissued or resold. No Notes shall be authenticated in exchange for canceled Notes 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 disposition, shall deliver a certificate of such disposition to the Company, at the Company’s written request in a Company Order.

Section 2.09    CUSIP Numbers. The Company in issuing the Notes may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in all notices issued to Holders as a convenience to such Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or on such notice and that reliance may be placed only on the other identification numbers printed on the Notes. The Company shall promptly notify the Trustee in writing of any change in the “CUSIP” numbers.

Section 2.10    Additional Transfer and Exchange Requirements.

(a)Notwithstanding any other provisions of this Indenture, 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.

(b)The provisions of subsections (i), (ii), (iii) and (iv) below shall apply only to Global Notes:

(i)The Depositary shall be a clearing agency registered under the Exchange Act. The Company has initially appointed DTC to act as Depositary with respect to any Global Note. Initially, any Global Note shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as Custodian for Cede & Co. If (A) the Depositary notifies the Company at any time that the Depositary is unwilling or unable to continue as depositary for the Global Notes and a successor depositary is not appointed within 90 days, (B) the Depositary ceases to be registered as a clearing agency under the Exchange Act and a successor depositary is not appointed within 90 days, (C) an Event of Default with respect to the Notes has occurred and is continuing and a beneficial owner of any Note requests that its beneficial interest therein be issued as a Physical Note, or (D) a beneficial owner of a Note requests its beneficial interest to be issued as a Physical Note, the Company shall execute, and the Trustee, upon receipt of an Officer’s Certificate and a Company Order for the authentication and delivery of Notes, shall authenticate and deliver (x) in the case of clauses (C) and (D), a Physical Note to such beneficial owner in a principal amount equal to the principal amount of such Note corresponding to such beneficial owner’s beneficial interest and (y) in the case of clause (A) or (B), Physical Notes to each beneficial owner of the related Global Notes (or a portion thereof) in an aggregate principal amount equal to the aggregate principal amount of such Global Notes in exchange for such Global Notes. If all of the beneficial interests are so exchanged, such Global Note will be surrendered to the Trustee and the Trustee will cause such Global Note to be canceled in accordance with the applicable procedures of the Depositary.

(ii)Physical Notes issued in exchange for all or a part of the Global Note pursuant to Section 2.05(b) shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, or, in the case of clauses (C) and (D) of Section 2.10(b)(i) above, the relevant beneficial owner, shall instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such Physical Notes to the Persons in whose names such Physical Notes are so registered.

(iii)At such time as all interests in a Global Note have been canceled, repurchased or transferred, such Global Note shall be, upon receipt thereof, canceled by the Trustee in accordance with standing procedures and existing instructions between the Depositary and the Custodian. At any time prior to such cancellation, if any interest in a Global Note is exchanged for Physical Notes, 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 principal amount of such Global Note shall, in accordance with the standing procedures and instructions existing between the Depositary and the Custodian, be appropriately

27

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.

(iv)Members of, or participants in, the Depositary shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Depositary, or the Trustee as its Custodian, or under a Global Note, and the Depositary (or its nominee) may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of a Global Note for all purposes whatsoever, except as otherwise stated herein. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any of their respective agents from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its participants, the operation of customary practices governing the exercise of the rights of a Holder of any Note.

(v)None of the Company, the Trustee or any agent of the Company or the Trustee shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any records relating to such beneficial ownership interests. None of the Company, the Trustee or any agent of the Company or the Trustee shall have any responsibility or obligation to any beneficial owner of an interest in the Global Notes, an agent member of, or a participant in, the Depositary or other person with respect to the accuracy of the records of the Depositary or its nominees or of any participant or member thereof, with respect to any ownership interest in the Global Notes or with respect to the delivery to any participant, agent member, beneficial owner or other Person (other than the Depositary) of any notice or the payment of any amount or delivery of any Notes (or other Note or property) under or with respect to such Notes. The rights of beneficial owners in any Global Notes shall be exercised only through the Depositary, subject to its applicable rules and procedures. The Trustee and each agent may rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its agent members, participants and any beneficial owners.

Section 2.11    Treatment of the Notes. The Company agrees, unless otherwise required by a change in Applicable Laws or as required by a determination (as defined in Code Section 1313(a) or any similar provision of state or local or non-U.S. law), (i) to treat the Notes as indebtedness for applicable income tax purposes and (ii) not to file any tax return, report or declaration inconsistent with the foregoing.

Section 2.12    Make Whole Amounts.

(a)If any Note is prepaid, repaid, redeemed or paid at any time prior to the Maturity Date, including, in connection with (i) an Optional Redemption, (ii) an acceleration of the Notes following the occurrence of an Event of Default pursuant to Section 6.02 or (iii) a Change of Control, then in addition to the principal amount of the Notes and other Obligations, the Company shall contemporaneously pay in cash (A) any accrued and unpaid interest owed on such principal and (B) the Make Whole Amount, in each case, applicable to the principal amount of the Notes so prepaid, repaid, redeemed, paid or otherwise reduced.

(b)The Make Whole Amount shall automatically be due and payable at any time any of the Notes subject to such amounts become due and payable prior to the applicable Maturity Date of the applicable Notes in accordance with the terms hereof as though such Indebtedness was voluntarily prepaid on the date such Notes become due and payable and shall constitute part of the Obligations, whether due to acceleration pursuant to the terms of this Agreement, by operation of law or otherwise (including, without limitation, on account of any bankruptcy filing), in view of the impracticability and extreme difficulty of ascertaining the actual amount of damages to the Holders or profits lost by the Holders as a result of such acceleration, and by mutual agreement of the parties as to a reasonable estimation and calculation of the lost profits or damages of the Holders as a result thereof. Any Make Whole Amount payable pursuant to this Agreement shall be presumed to be the liquidated damages sustained by each Holder as the result of the early termination, acceleration or prepayment and each Note Party agrees that such Make Whole Amount is reasonable under the circumstances currently existing. The Make Whole Amount shall also be payable in the event the Obligations (and/or this Agreement) are satisfied or released by foreclosure (whether by power of judicial proceeding), deed in lieu of foreclosure or by any other means or the Obligations are reinstated pursuant to Section 1124 of the Bankruptcy Code. If the Make Whole Amount becomes due and payable pursuant to this Agreement, such Make Whole Amount shall be deemed to be principal of the applicable Notes and Obligations under this Agreement and interest shall accrue on the full principal amount of such Notes (including the Make Whole Amount) from and after the applicable triggering event. In the event the Make Whole Amount is determined not to be due and payable by order of any court of competent jurisdiction, including, without limitation, by operation of the Bankruptcy Code, despite such a triggering event having occurred, such Make Whole Amount shall nonetheless constitute Obligations under this Agreement for all purposes hereunder. EACH NOTE PARTY HEREBY WAIVES THE PROVISIONS OF ANY PRESENT OR FUTURE STATUTE OR LAW THAT PROHIBITS OR MAY PROHIBIT THE COLLECTION OF THE MAKE WHOLE AMOUNT AND ANY DEFENSE TO PAYMENT, WHETHER SUCH DEFENSE MAY BE BASED IN PUBLIC POLICY OR

28

AMBIGUITY. The Note Parties, the Trustee, the Collateral Agent and the Holders acknowledge and agree that any Make Whole Amount due and payable in accordance with this Agreement shall not constitute unmatured interest, whether under Section 5.02(b)(3) of the Bankruptcy Code or otherwise. Each Note Party further acknowledges and agrees, and waives any argument to the contrary, that payment of such amount does not constitute a penalty or an otherwise unenforceable or invalid obligation. Each Note Party expressly agrees that (i) the Make Whole Amount is reasonable and is the product of an arm’s-length transaction between sophisticated business people, ably represented by counsel, (ii) the Make Whole Amount shall be payable notwithstanding the then prevailing market rates at the time payment is made, (iii) there has been a course of conduct between the Holders and the Note Parties giving specific consideration in this transaction for such agreement to pay the Make Whole Amount, (iv) the Note Parties shall be estopped hereafter from claiming differently than as agreed to in this Section 2.12, (v) the agreement of the Note Parties to pay the Make Whole Amount is a material inducement to the Holders to hold the Notes, and (vi) the Make Whole Amount represents a good faith, reasonable estimate and calculation of the lost profits, losses or other damages of the Holders and that it would be impractical and extremely difficult to ascertain the actual amount of damages to the Holders or profits lost by the Holders as a result of such event. The Make Whole Amount shall be paid by the Company to each of the Holders based on the respective principal amount of such Holder’s Notes prepaid, repaid, redeemed, accelerated, paid or otherwise reduced on the date of such prepayment, repayment, redemption, payment, acceleration or other reduction.

Article 3
SATISFACTION AND DISCHARGE

Section 3.01    Satisfaction and Discharge. This Indenture, the Notes and the other Notes Documents (other than the Exchange Agreement, which will remain in full force and effect following any repayment in full of the Obligations and any termination of this Indenture) shall cease to be of further effect when (a) all Obligations have been paid in full and all Notes theretofore authenticated and delivered (other than Notes which have been destroyed, lost or stolen and which have been replaced, or paid as provided in Section 2.06) have been delivered to the Trustee for cancellation; or (b) the Company has irrevocably deposited with the Trustee to be delivered to Holders or delivered to Holders, as applicable, after all outstanding Notes have become due and payable, whether on the Maturity Date or an Optional Redemption Date, cash sufficient to pay all of the outstanding Notes (other than Notes which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 2.06), as the case may be, and pay in full all other Obligations and at the expense of the Company, the Company shall deliver to, the Trustee and the Collateral Agent, an Officer’s 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 Company to the Trustee under Section 7.06 shall survive. If the Trustee is unable to apply any cash in accordance with this Section 3.01 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s and any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to this Section 3.01; provided that if the Company has made any payment of principal of, premium, if any, or interest on, any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the cash and/or shares of Common Stock held by the Trustee or delivered to the Holders (it being understood that the Trustee shall have no obligation to hold shares of Common Stock).

Article 4
PARTICULAR COVENANTS OF THE COMPANY

Section 4.01    Payment of Principal and Interest. The Company covenants and agrees that it will cause to be paid the principal (including the Optional Redemption Price and, without duplication, the Make Whole Amount, in each case if applicable) of, and accrued and unpaid interest on each of the Notes at the places, at the respective times and in the manner provided herein and in the Notes.

Section 4.02    Maintenance of Office or Agency. The Company will maintain in the contiguous United States, an office or agency where the Notes may be surrendered for registration of transfer or exchange or presented for payment or repurchase (“Paying Agent”) and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company will give prompt written notice to the Trustee and the Paying Agent (if other than the Trustee) of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office or the office or agency of the Trustee in the contiguous United States.

The Company may also from time to time designate as co-Note Registrars one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes, may from time to time rescind such

29

designations and may approve any change in the office through which any Note Registrar, or Paying Agent acts; provided that no such designation, rescission or approval shall in any manner relieve the Company of its obligation to maintain an office or agency in the contiguous United States for such purposes. The Company will give prompt written notice to the Trustee of any such designation, rescission or approval and of any change in the location of any such other office or agency. The term “Paying Agent” includes any such additional or other offices or agencies, as applicable.

The Company hereby initially designates the Trustee as the Paying Agent, Note Registrar and Custodian and the Corporate Trust Office as the office or agency in the contiguous United States where Notes may be surrendered for registration of transfer or exchange or for presentation for payment or repurchase and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served; provided that the Corporate Trust Office shall not be a place of legal process on the Company.

Section 4.03    Appointments to Fill Vacancies in Trustee’s Office. The Company, whenever necessary to avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section 7.09, a Trustee, so that there shall at all times be a Trustee hereunder.

Section 4.04    Provisions as to Paying Agent.

(a)If the Company shall appoint a Paying Agent other than the Trustee, the Company will cause such Paying Agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 4.04:

(i)that it will hold all sums held by it as such agent for the payment of the principal (including the Optional Redemption Price, and the Make Whole Amount, in each case if applicable) of, and accrued and unpaid interest on, the Notes in trust for the benefit of the Holders of the Notes;

(ii)that it will give the Trustee prompt written notice of any failure by the Company to make any payment of the principal (including the Optional Redemption Price, and the Make Whole Amount, in each case if applicable) of, and accrued and unpaid interest on, the Notes when the same shall be due and payable; and

(iii)that at any time during the continuance of an Event of Default, upon request of the Trustee, it will forthwith pay to the Trustee all sums so held in trust.

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

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

(c)Anything in this Section 4.04 to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture in accordance with Article 3, or for any other reason, pay, cause to be paid or deliver to the Trustee all sums or amounts held in trust by the Company or any Paying Agent (if the Company is not then acting as the Paying Agent) hereunder as required by this Section 4.04, such sums or amounts to be held by the Trustee upon the trusts herein contained and upon such payment or delivery by the Company or any Paying Agent to the Trustee, the Company or such Paying Agent shall be released from all further liability but only with respect to such sums or amounts. Upon the occurrence of any event specified in Section 6.01(f), the Trustee shall automatically become the Paying Agent.

(d)Subject to the requirements of any applicable abandoned property laws, any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the

30

principal (including the Optional Redemption Price, and the Make Whole Amount, in each case if applicable) of, accrued and unpaid interest on, and the cash due upon repayment of any Note and remaining unclaimed for two years (or as of any common law escheatment date) after such principal (including the Optional Redemption Price, and the Make Whole Amount, in each case if applicable), interest, if any, or cash shall be paid to the Company on request of the Company contained in an Officer’s Certificate, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent (if the Company is not then acting as the Paying Agent) with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease.

Section 4.05    Preservation of Existence, Etc. Each Note Party shall preserve and maintain in full force and effect (a) its organizational existence and good standing (to the extent such concept is applicable) under the Applicable Laws of its jurisdiction of incorporation, organization or formation, as applicable, and (b) all qualifications to do business in each other jurisdiction not covered by clause (a) above in which the failure to be so qualified would reasonably be expected, individually or in the aggregate, to have a Material Adverse Effect; provided that the foregoing shall not prohibit any transaction not otherwise prohibited under the other sections of this Article 4.

Section 4.06    Compliance with Laws. Except in each case as would not reasonably be expected, individually or in the aggregate, to have a Material Adverse Effect, the Note Parties shall, and shall cause their Subsidiaries to comply with all Applicable Laws.

Section 4.07    Authorizations. The Note Parties shall, and shall cause their Subsidiaries to, obtain, make and keep in full force and effect all Authorizations required to conduct their businesses, except where the failure to make and keep Authorizations in full force and effect would not reasonably be expected, individually or in the aggregate, to have a Material Adverse Effect.

Section 4.08    Maintenance of Property. In each case except as otherwise permitted by this Indenture, each Note Party shall maintain, and shall cause each of its Subsidiaries to maintain, and preserve all its assets and property that are material to its businesses in good working order and condition, ordinary wear and tear and casualty and condemnation excepted and shall make all necessary repairs thereto and renewals and replacements thereof in the ordinary course of business, except where the failure to do so would not reasonably be expected, individually or in the aggregate, to have a Material Adverse Effect.

Section 4.09    Insurance. Except when the failure to do so has not resulted in, and is not reasonably expected, individually or in the aggregate, to result in, a Material Adverse Effect, the Note Parties shall, and shall cause each of their Subsidiaries to, maintain with financially sound and reputable insurance companies insurance with respect to their assets, properties and businesses, against such hazards and liabilities, of such types and in such amounts, as is customarily maintained by companies in the same or similar businesses similarly situated (in the good faith judgment of the management of the Company). Each such policy of insurance shall, within forty-five (45) days of the Closing Date (or such later date as may be agreed to by the Administrative Determination Holder(s), prior to the Braidwell Disposition Date, the Braidwell Holders, and prior to the Deerfield Disposition Date, the Deerfield Holders) (a) in the case of each liability policy, name the Collateral Agent (on behalf, and for the benefit, of, the Secured Parties) as an additional insured thereunder as its interests may appear and (b) in the case of each casualty insurance policy contain a lender’s loss payable clause or endorsement that names the Collateral Agent (on behalf, and for the benefit, of the Secured Parties), as the lender’s loss payee thereunder and, to the extent available, provide that the insurer will give at least thirty (30) days’ prior written notice to the Collateral Agent of any modification or cancellation of such policy (or ten (10) days’ prior written notice in the case of the failure to pay any premiums thereunder).

Section 4.10    Payment of Taxes. Each Note Party shall, and shall cause each of its Subsidiaries to, pay all material Taxes imposed upon it or any of its properties or assets or in respect of any of its income, businesses or franchises before any penalty accrues thereon, and all other material claims (including claims for labor, services, materials and supplies) for sums that have become due and payable prior to the time when any penalty or fine shall be incurred with respect thereto; provided, that no such Tax or claim need be paid if it is being contested in good faith by appropriate Proceedings promptly instituted and diligently conducted, so long as adequate reserves or other appropriate provision, if any, as shall be required in conformity with GAAP shall have been made therefor.

Section 4.11    SEC Documents; Financial Statements; Rule 144A Information. The Company shall comply in all material respects with its filing requirements under Section 13 or 15(d) of the Exchange Act, as applicable and shall, within five (5) Business Days after the filing with the Commission of each quarterly report on Form 10-Q and annual report on Form 10-K, deliver to the Trustee, with a copy to the Braidwell Holders (for so long as such Braidwell Holders are included in the Required Holders) and the Deerfield Holders (for so long as such

31

Deerfield Holders are including in the Required Holders), a Compliance Certificate; provided that any material (and otherwise nonpublic) information to be contained in such Compliance Certificate shall be included in such quarterly or annual report. Commencing with the Company’s annual report on Form 10-K for the year ended December 31, 2023, in each quarterly report on Form 10-Q and annual report on Form 10-K filed by the Company, the Company shall report its Liquidity as of the last day of the last fiscal quarter or year covered by such report. Without limiting the foregoing, from the Closing Date until the first date on which no Notes remain outstanding (the “Reporting Period”), the Company shall timely file (after giving effect to any extensions pursuant to Rule 12b-25 under the Exchange Act) all SEC Documents required to be filed with the Commission pursuant to the Exchange Act, and the Company shall not terminate the registration of the Common Stock under the Exchange Act or otherwise terminate its status as an issuer required to file reports under the Exchange Act, even if the securities laws would otherwise permit any such termination. None of such SEC Documents, when filed or furnished, shall contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. All financial statements including in any such SEC Documents shall fairly present the consolidated financial position of the Company and its Subsidiaries as of the dates thereof and the consolidated results of their operations and cash flows for the periods presented and shall have been prepared on a going concern basis in accordance with GAAP, consistently applied (subject, in the case of unaudited quarterly financial statements, to normal year-end adjustments that are not material individually or in the aggregate and lack of footnote disclosures). Any audit or report of the Company’s independent certified public accountants on any financial statements included in any such SEC Document shall (i) contain an unqualified opinion (subject to the exception set forth below in clause (ii) of this sentence), stating that such consolidated financial statements present fairly in all material respects the consolidated financial position and results of operations and cash flows of the Company and its Subsidiaries as of the dates thereof and for the periods presented and have been prepared in conformity with GAAP applied on a basis consistent with prior years, and (ii) at any time after December 31, 2024, not include any explanatory paragraph expressing substantial doubt as to going concern status (other than solely with respect to the Maturity Date), and no financial statements included in any SEC Documents shall include any statement in the footnotes thereto that indicates that there is substantial doubt about the Company’s ability to continue as a going concern (or any statement to similar effect). Not later than the earlier of (x) the Company’s filing of any annual report on Form 10-K for any fiscal year and (y) the due date therefor (without giving effect to any extensions pursuant to Rule 12b-25 under the Exchange Act), the Company shall publicly issue an earnings release reporting the Company’s operating results, including Revenue, for the fourth quarter of such fiscal year. All financial information including in any such earnings release shall fairly present the consolidated financial position of the Company and its Subsidiaries as of the dates thereof and the consolidated results of their operations and cash flows for the periods presented and shall have been prepared on a going concern basis in accordance with GAAP, consistently applied. Within forty-five (45) days after the end of each fiscal year of the Company, the Note Parties and their Subsidiaries shall deliver to the Trustee, with a copy to the Braidwell Investors (for so long as the Braidwell Investors are included in the Required Holders) and the Deerfield Holders (for so long as such Deerfield Holders are including in the Required Holders), an updated Perfection Certificate. All calculations in any Compliance Certificate will be made in accordance with GAAP, if applicable, and the applicable terms and provisions of this Indenture and the other Notes Documents. Upon the reasonable request of any Secured Party, the Note Parties and their Subsidiaries shall promptly deliver to such Secured Party such additional business, financial, corporate affairs, perfection certificates (including Perfection Certificates), items or documents related to creation, perfection, protection, maintenance, enforcement or priority of the Collateral Agent’s Liens in the Collateral as any Secured Party may from time to time reasonably request.

(a)If at any time the Company is not subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the Company shall, so long as any of the Notes shall, at such time, constitute “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, furnish to Holders, beneficial owners and prospective purchasers of such Notes, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the resale of such Notes pursuant to Rule 144A.

(b)Delivery of the reports and information described in subsection (a) above to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute actual or constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to conclusively rely on an Officer’s Certificate).

Section 4.12    Cash Management Systems. Each Note Party shall enter into, and cause each depository, securities intermediary or commodities intermediary to enter into, Control Agreements with respect to each deposit, securities, commodity or similar account maintained by such Person (other than Excluded Accounts) (such deposit, securities, commodity or similar accounts, “Controlled Accounts”) as of and after the Closing Date; provided, however, that, the Note Parties shall have until the date that is sixty (60) days following the Closing Date, the closing date of any Permitted Acquisition or the opening of any new account, as applicable (or, in each case, such later date as may be agreed to by the Administrative Determination Holder(s), prior to the Braidwell Disposition

32

Date, the Braidwell Holders, and prior to the Deerfield Disposition Date, the Deerfield Holders) to comply with the provisions of this Section 4.12 with regard to such accounts (other than Excluded Accounts) of the Note Parties.

Section 4.13    Further Assurances. Promptly upon the reasonable request of the Required Holders, the Collateral Agent or the Trustee, the Note Parties shall (and, subject to the limitations set forth herein and in the other Notes Documents, shall cause each of their Subsidiaries (other than Excluded Subsidiaries) to) take such additional actions and execute such instruments, documents, certificates and financing and continuation statements as the Administrative Determination Holder(s), prior to the Braidwell Disposition Date, the Braidwell Holders, or prior to the Deerfield Disposition Date, the Deerfield Holders may reasonably require from time to time in order to effectuate the purposes and objectives of this Agreement and the applicable Security Documents, in each case subject to the limitations set forth herein and in the other Notes Documents.

(a)Without limiting the generality of the foregoing, the Note Parties shall cause each of their Subsidiaries (other than Excluded Subsidiaries) as of the date hereof, or within thirty (30) days (or such later date as agreed by the Administrative Determination Holder(s), prior to the Braidwell Disposition Date, the Braidwell Holders, and prior to the Deerfield Disposition Date, the Deerfield Holders in their reasonable discretion) after the date of the formation (including pursuant to a Division/Series Transaction), acquisition thereof or becoming a Subsidiary that is not an Excluded Subsidiary, to guaranty the Notes and to cause each such Subsidiary to grant to the Collateral Agent, for the benefit of the Secured Parties, a security interest in, subject to the limitations set forth herein and in the Notes Documents, all of such Subsidiary’s assets and property to secure such guaranty and to take such other actions reasonably requested by the Administrative Determination Holder(s), prior to the Braidwell Disposition Date, the Braidwell Holders, or prior to the Deerfield Disposition Date, the Deerfield Holders or the Trustee or Collateral Agent with respect to making any such Subsidiary a Note Party under the Notes Documents, and, with respect to any Subsidiary (other than an Excluded Subsidiary) formed, acquired or no longer being an Excluded Subsidiary after the Closing Date, within thirty (30) days (or such later date as agreed by the Administrative Determination Holder(s), prior to the Braidwell Disposition Date, the Braidwell Holders, and prior to the Deerfield Disposition Date, the Deerfield Holders in their reasonable discretion) after the date of the formation (including pursuant to a Division/Series Transaction), acquisition thereof or no longer being an Excluded Subsidiary, cause such Subsidiary to enter into a supplemental indenture in the form of Exhibit B and otherwise in accordance with Article 10. Furthermore, the Company shall notify Collateral Agent in writing (i) within thirty (30) days (or such later date as agreed by the Administrative Determination Holder(s), prior to the Braidwell Disposition Date, the Braidwell Holders, and prior to the Deerfield Disposition Date, the Deerfield Holders in their reasonable discretion) after the date of the formation (including pursuant to a Division/Series Transaction) or acquisition of any Subsidiary or becoming a Subsidiary that is not an Excluded Subsidiary or (ii) when required under the Security Agreement, of the issuance by or to any Note Party (other than by the Company) of any Stock. Each Note Party shall pledge, and shall cause each of its Subsidiaries (other than any Excluded Subsidiary) to pledge, in each instance, to the Collateral Agent, for the benefit of the Secured Parties, to secure the Obligations, any Stock (other than Excluded Assets) acquired by such Note Party promptly after (and in any event within thirty (30) days (or such later date as may be agreed to by the Administrative Determination Holder(s), prior to the Braidwell Disposition Date, the Braidwell Holders, and prior to the Deerfield Disposition Date, the Deerfield Holders in its reasonable discretion) after) of the date of formation or acquisition or becoming a Subsidiary that is no longer an Excluded Subsidiary with respect to such newly formed or acquired Subsidiary or a Subsidiary that is not an Excluded Subsidiary of (A) formation (including pursuant to a Division/Series Transaction), acquisition of such Subsidiary or becoming a Subsidiary that is not an Excluded Subsidiary or (B) the issuance of such Stock. The Note Parties shall deliver, or cause to be delivered, promptly after (and in any event within thirty (30) days (or such later date as may be agreed to by the Administrative Determination Holder(s), prior to the Braidwell Disposition Date, the Braidwell Holders, and prior to the Deerfield Disposition Date, the Deerfield Holders in their reasonable discretion) after) such date, with respect to such newly formed or acquired Subsidiary (that is not an Excluded Subsidiary), to the Collateral Agent (i) appropriate resolutions, secretary certificates, certified Organizational Documents, (ii) if requested by any Holder, legal opinions relating to the matters described in this Section 4.13 (which opinions shall be in form and substance reasonably acceptable to the Administrative Determination Holder(s) and, to the extent applicable, substantially similar to the opinions delivered on the Closing Date), (iii) joinder agreements with respect to the Security Agreement and, as reasonably requested by Collateral Agent at the direction of the Administrative Determination Holder(s), prior to the Braidwell Disposition Date, the Braidwell Holders, or prior to the Deerfield Disposition Date, the Deerfield Holders, all other Collateral Documents and other documents reasonably requested to establish the Lien of the Collateral Agent in all Collateral of such Subsidiary, and (iv) Uniform Commercial Code financing statements, documents and original collateral (including pledged Stock, other securities and instruments) and such other documents and agreements as may be reasonably required by the Collateral Agent or any Holder, all as necessary or desirable to establish and maintain a valid, perfected Lien in all Collateral in which such Subsidiary has an interest consistent with the terms of the Notes Documents, in each instance with respect to (1) each Note Party or Subsidiary formed (including pursuant to a Division/Series Transaction) or acquired or becoming a Subsidiary that is not an Excluded Subsidiary and (2) each Note Party or Person (other than a Note Party) whose Stock (other than Excluded Assets) is being pledged, in each case of clauses (1) and (2), after the Closing Date. In connection with each pledge of Stock, on or prior to the date of any such pledge of Stock, the Note Parties shall deliver, or cause to

Notwithstanding anything to the contrary contained in this Indenture or in any of the other Notes Documents, the amount immediately due and payable with respect to the principal of the Notes following an Event of Default shall be equal to the amount of such principal plus any interest, fees, costs, expenses and other Obligations owing or due by any Note Party), without presentment, demand, protest or other notice of any kind, all of which are hereby expressly waived by each Note Party.

The immediately preceding paragraph, however, is subject to the conditions that if, at any time after the principal of the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay installments of accrued and unpaid interest, if any, upon all Notes and the principal of any and all Notes that shall have become due otherwise than by acceleration (with interest on overdue installments of accrued and unpaid interest to the extent that payment of such interest is enforceable under Applicable Law, and on such principal at the rate borne by the Notes plus four percent at such time) and amounts due to the Trustee pursuant to Section 7.06, and if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) any and all existing Events of Default under this Indenture, other than the nonpayment of the principal of and accrued and unpaid interest, if any, on Notes that shall have become due solely by such acceleration, shall have been cured or waived pursuant to Section 6.08, then and in every such case (except as provided in the immediately succeeding sentence) the Administrative Determination Holder(s), prior to the Braidwell Disposition Date, the Braidwell Holders, and prior to the Deerfield Disposition Date, the Deerfield Holders, by written notice to the Company and to the Trustee, may waive all Defaults or Events of Default with respect to the Notes and rescind and annul such declaration and its consequences and such Event of 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 of, or accrued and unpaid interest, if any, on, any Notes, (ii) a failure to repurchase any Notes when required, or (iii) a Default or Event of Default in respect of a covenant or provision hereof which under Article 10 may not be modified or amended without the consent of each Holder of an outstanding Note affected.

Notwithstanding anything to the contrary in this Section 6.02, neither the Trustee nor any Holder of the Notes (including any Braidwell Holders or Deerfield Holders) shall have the right to declare any portion of the principal of, or any accrued and unpaid interest, or the Make Whole Amount on any Notes (including PIK Notes) immediately due and payable pursuant to this Section 6.02 upon the occurrence of an Event of Default specified in Section 6.01(h) that occurs during Forbearance Period until after such Forbearance Period.

In the event the Company enters into an agreement in respect of any transaction that will (or is reasonably likely to) result in a Change of Control, the Company shall, within one Business Day thereof, make a public announcement of the terms and conditions thereof.

Section 6.03    Payments of Notes on Default; Suit Therefor. If an Event of Default described in clause (a) of Section 6.01 shall have occurred and is continuing, the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of the Notes, the whole amount then due and payable on the Notes for principal and interest, if any, with interest on any overdue principal and interest, if any, at the rate borne by the Notes plus four percent at such time, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee under Section 7.06. If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, or the Collateral Agent may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon the Notes, wherever situated.

In the event there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor on the Notes under Title 11 of the Bankruptcy Code, or any other Applicable Law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the Company or such other obligor, the property of the Company or such other obligor, or in the event of any other judicial proceedings relative to the Company or such other obligor upon the Notes, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 6.03, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal and accrued and unpaid interest, if any, in respect of the Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents and to take such other actions as it may deem necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceedings relative to the Company or any other obligor on the Notes, its or their creditors, or its or their property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due to the Trustee under Section 7.06; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Holders to make such payments to the Trustee, as administrative expenses, and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including agents and counsel fees, and including any other amounts due to the Trustee under Section 7.06, incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, advances and disbursements out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and other property that the Holders of the Notes may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise.

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

All rights of action and of asserting claims under this Indenture, or under any of the Notes, may be enforced by the Trustee without the possession of any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee and the Collateral Agent, their agents and counsel, be for the ratable benefit of the Holders of the Notes.

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

In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned because of any waiver pursuant to Section 6.08 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 Company, the Guarantors, the Holders and the Trustee shall, subject to any determination in

49

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

Section 6.04    Application of Monies Collected by Trustee. Any monies or property 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 or property, upon presentation of the several Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid:

First, to the payment of all amounts due the Trustee, Paying Agent, Registrar, and Custodian under this Indenture and to the Collateral Agent for amounts due to it under this Indenture and the other Notes Documents;

Second, in case the principal of the outstanding Notes shall not have become due and be unpaid, to the payment of interest on the Notes in default in the order of the date due of the payments of such interest, if any, 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, plus four percent, 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 then owing and unpaid upon the Notes for principal and interest, if any, and, to the extent that such interest has been collected by the Trustee, upon overdue installments of interest at the rate borne by the Notes at such time plus four percent, and in case such monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Notes, then to the payment of such principal and interest, if any, 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 and accrued and unpaid interest, if any; and

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

Section 6.5    Proceedings by Holders. Except to enforce the right to receive payment of principal or interest when due, no Holder of any Note shall have any right by virtue of or by availing of any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other similar official, or for any other remedy hereunder, unless, such Holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as herein provided;

(a)Holders of at least 25% in aggregate principal amount of the Notes then outstanding, or, prior to the Braidwell Disposition Date, the Braidwell Holders, or, prior to the Deerfield Disposition Date, the Deerfield Holders, shall have made written request upon the Trustee to institute such action, suit or proceeding shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and such Holders shall have offered to the Trustee such indemnity or security reasonably satisfactory to it against any loss, liability or expense to be incurred therein or thereby; and

(b)the Trustee shall have failed to institute such proceeding within 60 days after such notice, request and offer and shall not have received from the Required Holders a direction inconsistent with such request within 60 days after such notice, request and offer, 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). For the protection and enforcement of this Section 6.05, 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 of and (y) accrued and unpaid interest, if any, on or after the respective due dates expressed or provided for in such Note or in this Indenture, or to institute suit for the enforcement of any such payment or delivery, as the case may be, on or after such respective dates against the Company shall not be impaired or affected without the consent of such Holder. The Trustee does not have an affirmative duty to ascertain whether or not a Holder’s actions or forbearances are unduly prejudicial to any other Holder.

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

Section 6.07    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 provided in law or equity, 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 6.05, 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 6.08    Direction of Proceedings and Waiver of Defaults by the Required Holders. The Required Holders 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, (b) the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction and (c) the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any of the Holders unless such Holders have offered (and if requested, provided) to the Trustee indemnity or security satisfactory to it against any loss, liability or expense that might be incurred by it in compliance with such request or direction. The Trustee may refuse to follow any direction that it determines is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal liability. The Required Holders may on behalf of the Holders of all of the Notes waive any past Default or Event of Default hereunder and its consequences except (1) a default in the payment of accrued and unpaid interest, if any, on, or the principal of, the Notes when due that has not been cured pursuant to the provisions of Section 6.01, (2) [reserved] or (3) a default in respect of a covenant or provision hereof which under Article 10 cannot be modified or amended without the consent of each Holder of an outstanding Note affected. Upon any such waiver the Company, the Trustee and the Holders of the Notes shall be restored to their former positions and rights hereunder; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as permitted by this Section 6.08, 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 6.09    Notice of Defaults.

Section 6.10    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 6.10 (to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Notes at the time outstanding, determined in accordance with Section 8.04, or to any suit instituted by any Holder for the enforcement of the payment of the principal of or accrued and unpaid interest, if any, on any Note on or after the due date expressed or provided for in such Note.

Section 6.11    Injunction; Damages. In the event that the Company attempts to consummate a transaction constituting a Change of Control without delivering or causing to be delivered in cash 100% of the principal amount of the Notes, plus the Make Whole Amount, plus accrued and unpaid interest, if any, and any amounts then due and payable prior to or concurrently with consummation of such transaction, each Holder shall

51

Article 7
CONCERNING THE TRUSTEE AND COLLATERAL AGENT

Section 7.01    Duties and Responsibilities of Trustee. The Trustee, prior to the occurrence of an Event of Default and after the curing or waiver of all Events of Default that may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In the event an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers conferred on it by this Indenture solely at the discretion of the Administrative Determination Holder(s), prior to the Braidwell Disposition Date, the Braidwell Holders, and prior to the Deerfield Disposition Date, the Deerfield Holders (who shall be presumed to act for the Required Holders unless and until the Trustee receives written notice from the Required Holders that they object to an action proposed to be taken by the Administrative Determination Holder(s), prior to the Braidwell Disposition Date, the Braidwell Holders, and prior to the Deerfield Disposition Date, the Deerfield Holders ) or the Required Holders; provided that if an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any of the Holders unless such Holders have offered (and, if requested, provided) to the Trustee indemnity or security satisfactory to it against any loss, liability or expense that might be incurred by it in compliance with such request or direction.

No provision of this Indenture shall be construed to relieve the Trustee from liability for its own grossly negligent action, its own grossly negligent failure to act or its own willful misconduct, except that:

(a)prior to the occurrence of an Event of Default and after the curing or waiving of all Events of Default that may have occurred:

(i)the duties and obligations of the Trustee shall be determined solely by the express provisions of this Indenture, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(ii)in the absence of willful misconduct or gross negligence on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but, in the case of any such certificates or opinions that by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of any mathematical calculations or other facts stated therein);

(b)the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer or officers of the Trustee, unless it shall be proved that the Trustee was grossly negligent in ascertaining the pertinent facts;

(c)the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Required Holders relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture;

(d)whether or not therein provided, every provision of this Indenture relating to the conduct or affecting the liability of, or affording protection to, the Trustee shall be subject to the provisions of this Section;

(e)the Trustee shall not be liable in respect of any payment (as to the correctness of amount, entitlement to receive or any other matters relating to payment) or notice effected by the Company or any Paying Agent or any records maintained by any co-Note Registrar with respect to the Notes;

(f)if any party fails to deliver a notice relating to an event the fact of which, pursuant to this Indenture, requires notice to be sent to the Trustee, the Trustee may conclusively rely on its failure to receive such notice as reason to act as if no such event occurred, unless a Responsible Officer of the Trustee has received written notice of such event;

52

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

(h)in the event that the Trustee is also acting as Collateral Agent, Custodian, Note Registrar, Paying Agent or transfer agent hereunder, the rights, protections, immunities and indemnities afforded to the Trustee pursuant to this Indenture shall also be afforded to the Trustee in its capacity as Collateral Agent, Custodian, Note Registrar, Paying Agent or transfer agent; and

(i)under no circumstances shall the Trustee be liable in its individual capacity for the obligations evidenced by the Notes.

None of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers.

By acceptance of Notes, each Holder and beneficial owner agrees to provide such evidence of holdings, including, without limitation, through the procedures of the Depositary, as may be requested by the Trustee or Collateral Agent.  In determining whether Required Holders or Administrative Determination Holder(s), prior to the Braidwell Disposition Date, the Braidwell Holders, and prior to the Deerfield Disposition Date, the Deerfield Holders have consented, waived, agreed, determined, extended, participated in a direction or instruction or otherwise taken any action or made any determination under this Indenture or the other Note Documents, each of the Trustee and Collateral Agent shall be entitled to conclusively rely on such evidence and documentation as each of the Trustee and Collateral Agent shall determine, in its sole and absolute discretion, is necessary, including, without limitation, Officer’s Certificates, and neither the Trustee nor the Collateral Agent shall have any liability to any Person, including the Company, any Guarantor, any Holder or beneficial owner of the Notes for any action in reliance thereon, or any delay in acting pending receipt thereof.  The provisions of this clause (i) are for the sole benefit of the Trustee and the Collateral Agent and shall not impose a duty or obligation on either the Trustee or Collateral Agent to require any particular evidence or grant any Person, including the Company, any Guarantor, any Holder or beneficial owner of Notes, any right or remedy.

Each of the Trustee and the Note Collateral Agent shall be entitled to treat, conclusively, the Administrative Determination Holder(s), prior to the Braidwell Disposition Date, the Braidwell Holders, and prior to the Deerfield Disposition Date, the Deerfield Holders as holding or beneficially owning the principal amount of Notes set forth in the definition of “Required Holders” unless and until the Trustee and Collateral Agent have received written notice from either the Company or all Administrative Determination Holder(s), prior to the Braidwell Disposition Date, the Braidwell Holders, and/or prior to the Deerfield Disposition Date, the Deerfield Holders that they no longer satisfy such holding threshold.  Neither the Trustee nor the Collateral Agent (nor any of its agents) shall have any liability to the Company, any Guarantor, any Holder or beneficial owner of Notes or any other Person for acting in such reliance.

Section 7.02    Trustee Rights; Reliance on Documents, Opinions, Etc. Subject to Section 7.01:

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

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

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

(g)the Trustee shall be under no obligation to exercise any of the rights or powers vested by this Indenture at the request or demand of any of the Holders pursuant to this Indenture unless such Holders shall have offered to the Trustee security or indemnity satisfactory to the Trustee against the costs, expenses (including reasonable and documented attorneys’ fees and expenses) and liabilities which might be incurred by it in compliance with such request or demand;

(h)the Trustee may request that the Company deliver a certificate setting forth the names of individuals and/or titles of Authorized Officers authorized at such time to take specified actions by the Company pursuant to this Indenture, which certificate may be signed by any Person authorized to sign an Officer’s Certificate, including any Person specified as so authorized in any such certificate previously delivered and not superseded;

The Trustee shall not be charged with knowledge of any Default or Event of Default with respect to the Notes, unless written notice of such Default or Event of Default shall have been given to a Responsible Officer of the Trustee by the Company or by any Holder of the Notes.

Section 7.03    No Responsibility for Recitals, Etc. The recitals contained herein and in the Notes (except in the Trustee’s certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the same.

Section 7.04    Trustee, Paying Agents, or Note Registrar May Own Notes. The Trustee, any Paying Agent (other than the Company, if the Company is then acting as Paying Agent), or Note Registrar, in its individual or any other capacity, may become the owner or pledgee of Notes with the same rights it would have if it were not the Trustee, Paying Agent, or Note Registrar.

Section 7.05    Monies to Be Held in Trust. All monies received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received. Money held by the Trustee in trust hereunder need not be segregated from other funds or property except to the extent required by law or the Collateral Documents. The Trustee shall be under no liability for interest on any money received by it hereunder except as may be agreed from time to time by the Company and the Trustee.

Section 7.06    Compensation and Expenses of Trustee. The Company covenants and agrees to pay to the Trustee, in any capacity under this Indenture, from time to time, and the Trustee shall receive, such 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

54

Trustee and the Company, and the Company will pay or reimburse the Trustee upon its request for all reasonable and documented, out-of-pocket expenses, disbursements and advances reasonably incurred or made by the Trustee in accordance with any of the provisions of this Indenture in any capacity thereunder (including the reasonable and documented compensation and the expenses and disbursements of its agents and counsel and of all Persons not regularly in its employ), except any such expense, disbursement or advance as shall have been caused by its gross negligence or willful misconduct, as determined by a final, nonappealable order of a court of competent jurisdiction. The Company also covenants to indemnify the Trustee in any capacity under this Indenture and any other document or transaction entered into in connection herewith and its officers, directors, employees and agents and any authenticating agent for, and to hold them harmless against, any loss, claim (whether asserted by the Company, a Holder or any other Person), damage, liability or expense incurred without gross negligence or willful misconduct on the part of the Trustee, its officers, directors, agents or employees, or such agent or authenticating agent, as the case may be, determined by a final, nonappealable order of a court of competent jurisdiction, and arising out of or in connection with the acceptance or administration of this Indenture, the exercise of its rights hereunder or in any other capacity hereunder, including the costs and expenses of defending themselves against any claim of liability in the premises. The obligations of the Company under this Section 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 6.04, funds held in trust herewith for the benefit of the Holders of particular Notes. The Trustee’s right to receive payment of any amounts due under this Section 7.06 shall not be subordinate to any other liability or indebtedness of the Company. The obligation of the Company under this Section 7.06 shall survive the satisfaction and discharge of this Indenture and the earlier resignation or removal or the Trustee. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The indemnification provided in this Section 7.06 shall extend to the officers, directors, agents and employees of the Trustee.

Article 8CONCERNING THE HOLDERS

Section 8.01    Action by Holders. Whenever in this Indenture it is provided that the Holders of a specified percentage of the aggregate principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action, the Holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Holders in person or by agent or proxy appointed in writing, or (b) by the record of the Holders voting in favor thereof at any meeting of Holders duly called and held in accordance with the provisions of Article 9, or (c) by a combination of such instrument or instruments and any such record of such a meeting of Holders. Whenever the Company or the Trustee solicits the taking of any action by the Holders of the Notes, the Company or the Trustee may, but shall not be required to, fix in advance of such solicitation, a date as the record date for determining Holders entitled to take such action. The record date if one is selected shall be not more than 15 days prior to the date of commencement of solicitation of such action.

Section 8.02    Proof of Execution by Holders. Subject to the provisions of Section 7.01, Section 7.02 and Section 9.05, proof of the execution of any instrument by a Holder or its agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The holding of Notes shall be proved by the Note Register or by a certificate of the Note Registrar. The record of any Holders’ meeting shall be proved in the manner provided in Section 9.06.

Section 8.03    Who Are Deemed Absolute Owners. The Company, the Trustee, any authenticating agent, any Paying Agent, and any Note Registrar shall deem the Person in whose name a Note shall be registered upon the Note Register to be, and shall treat it as, the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation of ownership or other writing thereon made by any Person other than the Company or any Note Registrar) for the purpose of receiving payment of or on account of the principal of and (subject to Section 2.03) accrued and unpaid interest, if any, on such Note; and neither the Company nor the Trustee nor any Paying Agent nor any Note Registrar shall be affected by any notice to the contrary. The sole registered

58

holder of a Global Note shall be the Depositary or its nominee. All such payments or deliveries so made to any Holder for the time being, or upon its order, shall be valid. Notwithstanding anything to the contrary in this Indenture or the Notes, following an Event of Default any holder of a beneficial interest in a Global Note may directly enforce against the Company, without the consent, solicitation, proxy, authorization or any other action of the Depositary or any other Person, such holder’s right to exchange such beneficial interest for a Physical Note in certificated form in accordance with the provisions of this Indenture.

Section 8.04    Company-Owned Notes Disregarded. In determining whether the Holders of the requisite aggregate principal amount of Notes have concurred in any direction, consent, waiver or other action under this Indenture, Notes that are owned by the Company, by any Subsidiary thereof shall be disregarded and deemed not to be outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, consent, waiver or other action only Notes that a Responsible Officer has received written notice that such Notes are so owned shall be so disregarded. For the avoidance of doubt, Notes held or beneficially owned by Braidwell Holders or Deerfield Holders shall not be disregarded for any purposes pursuant to this Section 8.04 or any other matter. Notes so owned that have been pledged in good faith may be regarded as outstanding for the purposes of this Section 8.04 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to so act with respect to such Notes and that the pledgee is not the Company, a Subsidiary thereof. In the case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an Officer’s Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described Persons; and, subject to Section 7.01, the Trustee shall be entitled to accept such Officer’s Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such determination.

Section 8.05    Revocation of Consents; Future Holders Bound. At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 8.01, of the taking of any action by the Holders of the percentage of the aggregate principal amount of the Notes specified in this Indenture in connection with such action, any Holder of a Note that is shown by the evidence to be included in the Notes the Holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided in Section 8.02, revoke such action so far as concerns such Note. Except as aforesaid, any such action taken by the Holder of any Note shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Note and of any Notes issued in exchange or substitution therefor or upon registration of transfer thereof, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor or upon registration of transfer thereof.

After any such supplemental indenture or any amendment or other supplement to the Notes Documents becomes effective, the Company shall give to the Holders a notice (with a copy to the Trustee) briefly describing such supplemental indenture or any amendment or other supplement to the Notes Documents. However, the failure to give such notice to all the Holders, or any defect in the notice, will not impair or affect the validity of the supplemental indenture.

Section 10.05    Evidence of Compliance of Supplemental Indenture to Be Furnished Trustee and Collateral Agent. In addition to the documents required by Section 19.05, the Trustee and the Collateral Agent shall receive an Officer’s Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture executed pursuant hereto complies with the requirements of this Article 10 and is permitted or authorized by this Indenture.

In addition to the foregoing, without the written consent of the Required Holders, the Company will not, and will not permit any of its Subsidiaries to, directly or indirectly, (i) exchange Common Stock or other securities of the Company or any other Person for any of the Obligations (or any portion thereof) or any other right or obligation hereunder or under the Notes or (ii) pay or cause to be paid, or otherwise give value or any consideration or cause to give value or any consideration to or for the benefit of any Holder (whether in cash, securities or any other assets), and no Holder shall accept any such securities, payment, value or other consideration, as consideration for, or otherwise as an inducement to engage in or accept, any exchange, purchase, payment, prepayment, redemption, repayment or other surrender of the Obligations (or any portion thereof), in each case, unless such securities, payment, giving of value or other consideration is offered to be provided to all Holders on a pro rata basis on the same terms, in the same manner and in the same time frame .

Section 16.02    Redemption Date; Notice of Optional Redemption. The Optional Redemption Date for any Optional Redemption will be a Business Day of the Company’s choosing that is no less than ten (10) calendar days after the date of the Optional Redemption Notice. To call any Notes for Optional Redemption, the Company shall give a notice of redemption (an “Optional Redemption Notice”) in accordance with Section 19.03 to the Trustee, the Paying Agent and each Holder of Notes.

The Optional Redemption Notice shall specify the Notes to be redeemed and shall state:

Notwithstanding the foregoing or anything else to the contrary contained herein, unless waived by the Administrative Determination Holder(s) prior to the Braidwell Disposition Date, the Braidwell Holders, and prior to the Deerfield Disposition Date, the Deerfield Holders, the Company may not deliver an Optional Redemption Notice unless (i) the Optional Redemption applies to all of the Notes on a pro rata basis (based on the principal amounts thereof) and (ii) the principal amount of the Notes being redeemed pursuant to such Optional Redemption Notice is not less than the lesser of $10,000,000 and the aggregate principal amount of all Notes then outstanding.

Section 16.04    Deposit of Redemption Price. Prior to 10:00 a.m. (New York City time) on the Optional Redemption Date in connection with an Optional Redemption, the Company shall deposit with the Paying Agent (or if the Company or a Subsidiary or an Affiliate of either of them is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the Optional Redemption Price of all Notes to be redeemed (together with accrued and unpaid interest and any other amounts payable thereon under this Indenture and the Notes, including the Make Whole Amount) on that date other than Notes or portions of Notes called for redemption which on or prior thereto have been delivered by the Company to the Trustee for cancellation. If such money is then held by the Company in trust and is not required for such purpose it shall be discharged from such trust.

64

If the Paying Agent holds money sufficient to pay the Optional Redemption Price, accrued and unpaid interest thereon and the Make Whole Amount with respect to any Notes for which an Optional Redemption Notice has been given, then, immediately on and after the Optional Redemption Date, interest on such Notes shall cease to accrue, whether or not the Notes are delivered to the Paying Agent, and all other rights of the Holders of such Notes shall terminate, other than the right to receive the Optional Redemption Price, accrued and unpaid interest thereon and the Make Whole Amount in respect of such Note, together with all Warrants issuable in respect of such Note.

Section 17.02    Collateral Agent.

(a)The Collateral Agent agrees that it will hold the security interests in the Collateral created under the Collateral Documents to which it is a party as contemplated by this Indenture, and any and all proceeds thereof, for the benefit of, the Secured Parties, without limiting the Collateral Agent’s rights, including under this Section 17.02, to act in preservation of the security interest in the Collateral. The Collateral Agent is authorized and empowered to appoint one or more co-collateral agents as it deems necessary or appropriate; provided, however, that no collateral agent hereunder shall be personally liable by reason of any act or omission of any other collateral agent hereunder.

(b)Neither the Trustee nor the Collateral Agent nor any of their respective officers, directors, employees, attorneys or agents will be responsible or liable for the existence, genuineness, value or protection of any Collateral, for the legality, enforceability, effectiveness, or sufficiency of the Collateral Documents, for the creation, perfection, priority, sufficiency or protection of any Lien, including not being responsible for payment of any Taxes, charges or assessments upon the Collateral or otherwise as to the maintenance of the Collateral, or for any defect or deficiency as to any such matters, or for any failure to demand, collect, foreclose or realize upon or otherwise enforce any of the Liens or Collateral Documents or any delay in doing so. Neither the Trustee nor the Collateral Agent nor any of their respective officers, directors, employees, attorneys or agents will be responsible or liable for making any filings or recordings to perfect or maintain the perfection of the Collateral Agent’s Lien in the Collateral, including the filing of any UCC financing statements, continuation statements, Mortgages or any filings with respect to the U.S. Patent and Trademark Office or U.S. Copyright Office.

(c)The Collateral Agent shall not have any duties or obligations except those expressly set forth in the Note Documents to which it is a party, and its duties hereunder shall be administrative in nature. Without limiting the generality of the foregoing, (1) the Collateral Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default or Event of Default has occurred and is continuing and, without limiting the generality of the foregoing, the use of the term “agent” herein and in the other Note Documents with reference to the Collateral Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any Applicable Law and instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties, (2) the Collateral Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers that are expressly contemplated by the Note Documents that, subject to the terms hereof, the Collateral Agent is required to exercise as directed in writing by the Administrative Determination Holder(s), prior to the Braidwell Disposition Date, the Braidwell Holders, and prior to the Deerfield Disposition Date, the Deerfield Holders (or such number or percentage of the Holders as shall be necessary, or as the Collateral Agent shall believe in good faith to be necessary, under the circumstances as provided in the Note Documents); provided that the Collateral Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Collateral Agent to liability or that is contrary to any Note Document or Applicable Laws, and (3) except as expressly set forth in the Note Documents to which it is a party, the Collateral Agent shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to any Note Party or any of its Affiliates that is communicated to or obtained by the Person serving as Collateral Agent or any of its Affiliates in any capacity. The Collateral Agent shall not be liable for any action taken or not

65

taken by it with the consent or at the request of the Administrative Determination Holder(s), prior to the Braidwell Disposition Date, the Braidwell Holders, and prior to the Deerfield Disposition Date, the Deerfield Holders (or such other number or percentage of the Holders as shall be necessary, or as the Collateral Agent shall believe in good faith shall be necessary, under the circumstances as provided in the Note Documents) or in the absence of its own gross negligence or willful misconduct as determined by the final and non-appealable judgment of a court of competent jurisdiction, in connection with its duties expressly set forth herein. The Collateral Agent shall be deemed not to have knowledge of any Default or Event of Default unless and until written notice thereof (stating that it is a “notice of default” and describing such Default or Event of Default) is given to a Responsible Officer of the Collateral Agent by the Company or any Holder. The Collateral Agent will be subject to such directions as may be given to it by the Trustee, or the Administrative Determination Holder(s), and prior to the Braidwell Disposition Date, the Braidwell Holders, and prior to the Deerfield Disposition Date, the Deerfield Holders, as applicable, from time to time (as required or permitted by this Indenture). The Collateral Agent will be subject to such directions as may be given to it by the Trustee or the Administrative Determination Holder(s), and prior to the Braidwell Disposition Date, the Braidwell Holders, and prior to the Deerfield Disposition Date, the Deerfield Holders, as applicable, from time to time (as required or permitted by this Indenture). Except as directed by the Administrative Determination Holder(s), prior to the Braidwell Disposition Date, the Braidwell Holders, and prior to the Deerfield Disposition Date, the Deerfield Holders, as applicable, as required or permitted by this Indenture and any other representatives, and only if indemnified to its satisfaction, the Collateral Agent will not be obligated:

(i)to act upon directions purported to be delivered to it by any Person;

(ii)to foreclose upon or otherwise enforce any Lien created under the Collateral Documents; or

(iii)except as expressly provided in Section 17.03, to take any other action whatsoever with regard to any or all of the Liens, Collateral Documents or Collateral.

(d)The Collateral Agent will be accountable only for amounts that it actually receives as a result of the enforcement of the Liens or Collateral Documents.

(e)In acting as Collateral Agent hereunder and under the Collateral Documents, the Collateral Agent shall be entitled to conclusively rely upon and enforce each and all of the rights, privileges, immunities, indemnities and benefits of the Trustee under Article 7; provided that any references in such Article 7 to “Trustee” shall be references to “Collateral Agent” and any references to “negligence” shall be references to “gross negligence”.

(f)The Collateral Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person (whether or not such Person in fact meets the requirements set forth in the Note Documents for being the signatory, sender or authenticator thereof). The Collateral Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person (whether or not such Person in fact meets the requirements set forth in the Note Documents for being the maker thereof), and may act upon any such statement prior to receipt of written confirmation thereof and shall not incur any liability for relying thereon. The Collateral Agent may consult with legal counsel, independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

(vii)to release or subordinate any Lien on any property granted to or held by the Collateral Agent under any Collateral Document to the holder of any Lien on such property that is permitted pursuant to Section 4.27(k);

Neither the Trustee nor the Collateral Agent shall be liable for any such release undertaken in reliance upon any such Officer’s Certificate, and notwithstanding any term hereof or in any other Notes Document to the contrary, the Trustee and the Collateral Agent shall not be under any obligation to release any such Lien and security interest, or execute and deliver or authorize the filing of any such instrument of release, satisfaction, discharge or termination, unless and until it receives such Officer’s Certificate.

(c)At any time when an Event of Default has occurred and is continuing and the maturity of the Notes has been accelerated (whether by declaration or otherwise) and the Trustee has delivered notice of acceleration to the Collateral Agent, no release of the Liens on the Collateral pursuant to the provisions of this Indenture or the Collateral Documents shall be effective as against the Holders.

67

legislative or other governmental enactment, rule or order that may be unconstitutional or otherwise invalid if the enforcement of, or compliance with, such enactment, rule or order would impair the Liens created under the Collateral Documents or be prejudicial to the interests of the Holders of the Notes).

Section 17.05     Authorization of Action to be Taken.

(a)Each Holder of Notes consents and agrees to the terms of each Collateral Document, as originally in effect and as amended, restated, amended and restated, supplemented or otherwise modified or replaced from time to time in accordance with its terms or the terms of this Indenture, authorizes and directs the Trustee and the Collateral Agent to enter into the Collateral Documents to which it is a party, authorizes and empowers the Trustee and the Collateral Agent to bind the Holders of Notes as set forth in the Collateral Documents to which it is party and to perform its obligations and exercise its rights and powers thereunder. Any request, demand, authorization, direction, notice, consent, waiver, approval, exercise of judgment or discretion, designation or other action provided or permitted by this Indenture to be given, taken or exercised by the Collateral Agent, shall be given, taken or exercised by the Collateral Agent at the direction of the Trustee who shall seek directions from the Administrative Determination Holder(s), prior to the Braidwell Disposition Date, the Braidwell Holders, and prior to the Deerfield Disposition Date, the Deerfield Holders unless such action is otherwise permitted pursuant to this Indenture or the other Note Documents (including, upon reliance of an Officer’s Certificate and/or Opinion of Counsel). Any notice, agreement, certificate or other document delivered to the Collateral Agent by the Company, any Guarantor or any other Person in connection with any of the Notes Documents, shall promptly be delivered by the Collateral Agent to the Trustee, which shall promptly deliver such notice, agreement, certificate or other document to the Holders of the Notes.

(c)Subject to the provisions of Section 7.01 and Section 7.02 and the terms and conditions set forth in any Pari Passu Intercreditor Agreement, the Trustee shall, upon the direction of the Administrative Determination Holder(s), prior to the Braidwell Disposition Date, the Braidwell Holders, and prior to the Deerfield Disposition Date, the Deerfield Holders, during the continuance of an Event of Default, on behalf of the Holders, direct the Collateral Agent to take all actions it deems necessary or appropriate in order to:

(i)foreclose upon or otherwise enforce any or all of the Liens created under the Collateral Documents;

(ii)enforce any of the terms of the Collateral Documents to which the Collateral Agent or Trustee is a party; or

(iii)collect and receive payment of any and all Obligations to the extent then due and payable.

Section 17.06     Powers Exercisable by Receiver or Trustee. In case the Collateral shall be in the possession of a receiver or trustee, lawfully appointed, the powers conferred in this Article 17 upon the Company or a Guarantor with respect to the release, sale or other disposition of such property may be exercised by such receiver or trustee, and an instrument signed by such receiver or trustee shall be deemed the equivalent of any similar instrument of the Company or a Guarantor or of any Responsible Officer or Responsible Officers thereof required by the provisions of this Article 17; and if the Trustee shall be in the possession of the Collateral under any provision of this Indenture, then such powers may be exercised by the Trustee.

Section 17.07     Release Upon Termination of the Company’s Obligations. In the event that the payment in full in cash of the principal of, together with any premium and accrued and unpaid interest on, the Notes and all other Obligations under this Indenture and the other Notes Documents that are due and payable at or prior to the time such principal, together with any premiums and accrued and unpaid and interest, shall have occurred, the Trustee shall deliver to the Company and the Collateral Agent a notice stating that the Trustee, on behalf of the Holders, disclaims and gives up any and all rights it has in or to the Collateral, and any rights it has under the Collateral Documents, and upon receipt by the Collateral Agent of such notice, the Collateral Agent shall be deemed not to hold a Lien in the Collateral on behalf of the Trustee and shall do or cause to be done (at the expense of the Company) all acts reasonably requested by the Company to release and discharge such Lien as soon as is reasonably practicable.

Article 18
GUARANTEE

Section 18.01     Guarantee. Subject to the provisions of this Article 18, each Guarantor hereby fully, unconditionally and irrevocably guarantees, as primary obligor and not merely as surety, jointly and severally with each other Guarantor, to each Holder of the Notes, the Trustee and the Collateral Agent the full and punctual payment when due, whether at maturity, by acceleration, by redemption or otherwise, of the principal of, premium, if any, and interest on the Notes, fees, expenses, indemnities and all other Obligations and liabilities of the Company under this Indenture (including interest accruing after the filing of any petition or application in bankruptcy, or the commencement of any insolvency, reorganization or like proceeding, relating to the Company or any Guarantor whether or not a claim for post-filing or post-petition interest is allowed in such proceeding and the obligations under Section 7.06) (all the foregoing being hereinafter collectively called the “Guaranteed Obligations”). Each Guarantor agrees that the Guaranteed Obligations will rank equally in right of payment with other Indebtedness of such Guarantor, except to the extent such other Indebtedness is subordinate to the Guaranteed Obligations, in which case the obligations of the Guarantors under the Note Guarantees will rank senior in right of payment to such other Indebtedness.

To evidence its Note Guarantee set forth in this Section 18.01, each Guarantor hereby agrees that this Indenture shall be executed on behalf of such Guarantor by an Authorized Officer of such Guarantor.

Each Guarantor hereby agrees that its Note Guarantee set forth in this Section 18.01 shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Note Guarantee on the Notes.

If an Authorized Officer whose signature is on this Indenture no longer holds that office at the time the Trustee authenticates the Note, the Note Guarantee shall be valid nevertheless.

Each Guarantor further agrees (to the extent permitted by law) that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from it, and that it will remain bound under this Article 18 notwithstanding any extension or renewal of any Guaranteed Obligation.

Each Guarantor waives presentation to, demand of payment from and protest to the Company of any of the Guaranteed Obligations and also waives notice of protest for nonpayment. Each Guarantor waives notice of any Default or Event of Default under the Notes or the Guaranteed Obligations.

Each Guarantor further agrees that its Note Guarantee herein constitutes a guarantee of payment when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Holder to any security held for payment of the Guaranteed Obligations.

Except as set forth in Section 18.02, the obligations of each Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason (other than payment of the Guaranteed Obligations in full), including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the Guaranteed Obligations of each Guarantor herein shall not be discharged or impaired or otherwise affected by (a) the failure of the Trustee or any Holder to assert any claim or demand or to enforce any right or remedy against the Company or any other Person under this Indenture, the Notes or any other agreement or otherwise; (b) any extension or renewal of any thereof; (c) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Notes or any other agreement; (d) the release of any security held by the Collateral Agent or any Holder for the Guaranteed Obligations; (e) the failure of the Trustee, the Collateral Agent or any Holder to exercise any right or remedy against any other Guarantor; (f) any change in the ownership of the Company; (g) any default, failure or delay, willful or otherwise, in the performance of the Guaranteed Obligations; or (h) any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of any Guarantor or would otherwise operate as a discharge of such Guarantor as a matter of law or equity.

Each Guarantor agrees that its Note Guarantee herein shall remain in full force and effect until payment in full of all the Guaranteed Obligations or such Guarantor is released from its Note Guarantee in compliance with Section 18.02 or Section 3.01. Each Guarantor further agrees that its Note Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of, premium, if any, or interest on any of the Guaranteed Obligations is rescinded or must otherwise be restored by any Holder upon the bankruptcy, insolvency or reorganization of the Company or otherwise.

69

In furtherance of the foregoing and not in limitation of any other right which any Holder has at law or in equity against any Guarantor by virtue hereof, upon the failure of the Company to pay any of the Guaranteed Obligations when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, each Guarantor hereby promises to and will, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders or the Trustee on behalf of the Holders an amount equal to the sum of (i) the unpaid amount of such Guaranteed Obligations then due and owing and (ii) accrued and unpaid interest on such Guaranteed Obligations then due and owing (but only to the extent not prohibited by law) (including interest accruing after the filing of any petition or application in bankruptcy or the commencement of any insolvency, reorganization or like proceeding relating to the Company or any Guarantor whether or not a claim for post filing or post-petition interest is allowed in such proceeding).

Each Guarantor further agrees that, as between such Guarantor, on the one hand, and the Holders, on the other hand, (x) the maturity of the Guaranteed Obligations guaranteed hereby may be accelerated as provided in this Indenture for the purposes of its Note Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations guaranteed hereby and (y) in the event of any such declaration of acceleration of such Guaranteed Obligations, such Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantor for the purposes of this Note Guarantee.

Each Guarantor also agrees to pay any and all fees, costs and expenses (including reasonable out-of-pocket attorneys’ fees and expenses) incurred by the Collateral Agent, Trustee or the Holders in enforcing any rights under this Section 18.01.

Each Guarantor assumes all responsibility for being and keeping itself informed of the Company’s and each other Guarantor’s financial condition and assets, and of all other circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations and the nature, scope and extent of the risks that such Guarantor assumes and incurs hereunder, and agrees that none of the Secured Parties will have any duty to advise such Guarantor of information known to it or any of them regarding such circumstances or risks.

Section 18.02     Limitation on Liability; Termination, Release and Discharge.

(a)Any term or provision of this Indenture to the contrary notwithstanding, the obligations of each Guarantor hereunder will be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Note Guarantee or pursuant to its contribution obligations under this Indenture, not render the obligations of such Guarantor under its Note Guarantee subject to avoidance under Applicable Laws as a fraudulent conveyance, fraudulent transfer or unjust preference, including under federal, foreign, or state law, or otherwise void or voidable under any similar laws affecting the rights of creditors generally.

(b)Any Note Guarantee of a Guarantor shall be automatically (and without any further action on the part of the Company or any Secured Party) be released and discharged and such Guarantor and its obligations under this Indenture and the other Notes Documents shall be automatically released and discharged:

(i)upon a sale, exchange, transfer or other disposition (including by way of consolidation, merger or amalgamation) of all of the Stock of such Guarantor to a Person other than to the Company or another Note Party and as otherwise permitted by this Indenture, including compliance with Section 4.25;

(ii)if after the date of this Indenture, any Guarantor is or becomes an Excluded Subsidiary in a transaction permitted under this Indenture and for a bona fide business purpose and not for the sole purpose of being released from its obligations as a Guarantor;

(iii)upon satisfaction and discharge of the Notes, as provided in Section 3.01;

(c)With respect to any release of any Note Guarantee, upon receipt of an Officer’s Certificate and an Opinion of Counsel each stating that all conditions precedent under this Indenture and the other Notes Documents, as applicable, to such release have been met and the Trustee or the Collateral Agent is authorized or permitted to execute and deliver the documents requested by the Company in connection with such release, and any instruments of termination, satisfaction, discharge or release prepared by the Company, the Trustee and the Collateral Agent shall execute, deliver or acknowledge (at the Company’s expense) such instruments or releases to evidence the release and discharge of any Note Guarantee or Guarantor permitted to be released pursuant to this Indenture. Neither the Trustee nor the Collateral Agent shall be liable for any such release undertaken in reliance upon any such Officer’s Certificate or Opinion of Counsel, and notwithstanding any term hereof or in any other Notes Document to the contrary, the Trustee and the Collateral Agent shall not be under any obligation to execute and deliver any such instrument of release, satisfaction, discharge or termination, unless and until it receives such Officer’s Certificate and Opinion of Counsel.

The provisions of this Section 18.03 shall in no respect limit the obligations and liabilities of each Guarantor to the Trustee, the Collateral Agent and the Holders and each Guarantor shall remain liable to the Trustee, the Collateral Agent and the Holders for the full amount guaranteed by such Guarantor hereunder.

Section 18.04     No Subrogation. Notwithstanding any payment or payments made by each Guarantor hereunder, no Guarantor shall be entitled to be subrogated to any of the rights of the Trustee, the Collateral Agent or any Holder against the Company or any other Guarantor or any collateral security or guarantee or right of offset held by the Trustee, the Collateral Agent or any Holder for the payment of the Guaranteed Obligations, nor shall any Guarantor seek or be entitled to seek any contribution or reimbursement from the Company or any other Guarantor in respect of payments made by such Guarantor hereunder, until all amounts owing to the Trustee, the Collateral Agent and the Holders by the Company on account of the Guaranteed Obligations are paid in full. If any amount shall be paid to any Guarantor on account of such subrogation rights at any time when all of the Guaranteed Obligations shall not have been paid in full, such amount shall be held by such Guarantor in trust for the Trustee, the Collateral Agent and the Holders, segregated from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to the Trustee in the exact form received by such Guarantor (duly indorsed by such Guarantor to the Trustee, if required), to be applied against the Guaranteed Obligations.

Section 18.05    Subordination. Notwithstanding any provision of this Indenture to the contrary, all rights of the Guarantors under Section 18.04, and all other rights of indemnity, contribution or subrogation under Applicable Laws or otherwise, shall be fully subordinated to the payment in full in cash of the Obligations. No failure on the part of the Company or any Guarantor to make the payments required by Section 18.04 (or any other payments required under Applicable Laws or otherwise) shall in any respect limit the obligations and liabilities of any Guarantor with respect to its obligations hereunder, and each Guarantor shall remain liable for the full amount of the obligations of such Guarantor hereunder.
